Most kids with peanut allergies do not outgrow them. But, with a little help, some might be able to better tolerate accidental exposures.

In January, the Food and Drug Administration approved Palforzia, a new drug designed to help kids who are allergic to peanuts react better, if they are accidentally exposed.

"Because there is no cure, allergic individuals must strictly avoid exposure to prevent severe and potentially life-threatening reactions," Dr. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research said at the time in a news release. "When used in conjunction with peanut avoidance, Palforzia provides an FDA-approved treatment option to help reduce the risk of these allergic reactions."

Palforzia is not designed to be administered during an allergic reaction, instead it works as an allergy exposure therapy: children ages 4 through 17 receive daily doses of peanut powder under clinical supervision, and slowly up-dose it over time.

In clinical trials, the strategy worked well, but not perfectly. When peanut-allergic kids were fed 600 milligrams of peanut protein, 67.2% of Palforzia recipients who'd been using the medication for six months tolerated it, while only 4% of the control group did.

First gene therapy to receivefull EU marketing authorization for eligible MLD patients

One-time treatment with Libmeldy has been shown to preserve motor and cognitive function

Achievement shared with research alliance partners Fondazione Telethon and Ospedale San Raffaele

BOSTON and LONDON and MILAN, Italy, Dec. 21, 2020 (GLOBE NEWSWIRE) -- Orchard Therapeutics (Nasdaq: ORTX), a global gene therapy leader, and its research alliance partners Fondazione Telethon and Ospedale San Raffaele, today announced that the European Commission (EC) granted full (standard) market authorization for Libmeldy (autologous CD34+ cells encoding the ARSA gene), a lentiviral vector-based gene therapy approved for the treatment of metachromatic leukodystrophy (MLD), characterized by biallelic mutations in theARSAgene leading to a reduction of the ARSA enzymatic activity in children with i) late infantile or early juvenile forms, without clinical manifestations of the disease, or ii) the early juvenile form, with early clinical manifestations of the disease, who still have the ability to walk independently and before the onset of cognitive decline. Libmeldy is the first therapy approved for eligible patients with early-onset MLD.

MLD is a very rare, fatal genetic disorder caused by mutations in the ARSA gene which lead to neurological damage and developmental regression. In its most severe and common forms, young children rapidly lose the ability to walk, talk and interact with the world around them, and most pass away before adolescence. Libmeldy is designed as a one-time therapy that aims to correct the underlying genetic cause of MLD, offering eligible young patients the potential for long-term positive effects on cognitive development and maintenance of motor function at ages at which untreated patients show severe motor and cognitive impairments.

Todays EC approval of Libmeldy opens up tremendous new possibilities for eligible MLD children faced with this devastating disease where previously no approved treatment options existed, said Bobby Gaspar, M.D., Ph.D., chief executive officer of Orchard. Libmeldy is Orchards first product approval as a company, and I am extremely proud of the entire team who helped achieve this milestone. We are grateful for and humbled by the opportunity to bring this remarkable innovation to young eligible patients in the EU.

With Libmeldy, a patients own hematopoietic stem cells (HSCs) are selected, and functional copies of the ARSA gene are inserted into the genome of the HSCs using a self-inactivating (SIN) lentiviral vector before these genetically modified cells are infused back into the patient. The ability of the gene-corrected HSCs to migrate across the blood-brain barrier into the brain, engraft, and express the functional enzyme has the potential to persistently correct the underlying disease with a single treatment.

The EC approval of Libmeldy comes more than a decade after the first patient was treated in clinical trials performed at our Institute, and ushers in a remarkable and long-awaited shift in the treatment landscape for eligible MLD patients, said Luigi Naldini, M.D, Ph.D., director of the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy. Our team at SR-Tiget has been instrumental in advancing the discovery and early-stage research of this potentially transformative therapy to clinical trials in support of its registration through more than 15 years of studies supported by Fondazione Telethon and Ospedale San Raffaele, and we are extremely proud of this achievement and what it means for patients and the field of HSC gene therapy.

MLD is a heart-breaking disease that causes immeasurable suffering and robs children of the chance of life, said Georgina Morton, chairperson of ArchAngel MLD Trust. As a community, we have been desperate for a treatment for young MLD patients, and we are incredibly excited to now have such a ground-breaking option approved in the EU.

The marketing authorization for Libmeldy is valid in all 27 member states of the EU as well as the UK, Iceland, Liechtenstein and Norway. Orchard is currently undertaking EU launch preparations related to commercial drug manufacturing, treatment site qualification and market access.

Data Supporting the Clinical and Safety Profile of Libmeldy

The marketing authorization for Libmeldy is supported by clinical studies in both pre- and early- symptomatic, early-onset MLD patients performed at the SR-Tiget. Early-onset MLD encompasses the disease variants often referred to as late infantile (LI) and early juvenile (EJ). Clinical efficacy was based on the integrated data analysis from 29 patients with early-onset MLD who were treated with Libmeldy prepared as a fresh (non-cryopreserved) formulation. Results of this analysis indicate that a single-dose intravenous administration of Libmeldy is effective in modifying the disease course of early-onset MLD in most patients.

Clinical safety was evaluated in 35 patients with MLD (the 29 patients from the integrated efficacy analysis as well as six additional patients treated with the cryopreserved formulation of Libmeldy). Safety data indicate that Libmeldy was generally well-tolerated. The most common adverse reaction attributed to treatment with Libmeldy was the occurrence of anti-ARSA antibodies (AAA) reported in five out of 35 patients. Antibody titers in all five patients were generally low and no negative effects were observed in post-treatment ARSA activity in the peripheral blood or bone marrow cellular subpopulations, nor in the ARSA activity within the cerebrospinal fluid. In addition to the risks associated with the gene therapy, treatment with Libmeldy is preceded by other medical interventions, namely bone marrow harvest or peripheral blood mobilization and apheresis, followed by myeloablative conditioning, which carry their own risks. During the clinical studies, the safety profiles of these interventions were consistent with their known safety and tolerability.

About MLD and Libmeldy

MLD is a rare and life-threatening inherited disease of the bodys metabolic system occurring in approximately one in every 100,000 live births. MLD is caused by a mutation in the arylsulfatase-A (ARSA) gene that results in the accumulation of sulfatides in the brain and other areas of the body, including the liver, gallbladder, kidneys, and/or spleen. Over time, the nervous system is damaged, leading to neurological problems such as motor, behavioral and cognitive regression, severe spasticity and seizures. Patients with MLD gradually lose the ability to move, talk, swallow, eat and see. In its late infantile form, mortality at five years from onset is estimated at 50% and 44% at 10 years for juvenile patients.1

Libmeldy (autologous CD34+ cell enriched population that contains hematopoietic stem and progenitor cells (HSPC) transduced ex vivo using a lentiviral vector encoding the human arylsulfatase-A (ARSA) gene), also known as OTL-200, is approved in the European Union for the treatment of MLD in eligible early-onset patients. In the U.S., OTL-200 is an investigational therapy which has not been approved by the U.S. Food and Drug Administration (FDA) for any use. Libmeldy was acquired from GSK in April 2018 and originated from a pioneering collaboration between GSK and the Hospital San Raffaele and Fondazione Telethon, acting through their joint San Raffaele-Telethon Institute for Gene Therapy in Milan, initiated in 2010.

Following the harassment of Christian Cooper in Central Park in May 2020, Black birders created #BlackBirdersWeek to celebrate Black nature enthusiasts and highlight their belonging in outdoor spaces. Since then, dozens of campaigns have emerged to amplify and appreciate Black academics, scientists, and naturalists.

Next up is #BlackInMarineScienceWeek, running from November 29th to December 5th.Led by founder Dr. Tiara Moore and organizers Amani Webber-Schultz, Dr. Camille Gaynus, Carlee Jackson, Al Troutman, Jasmin Graham, Jeanette Davis, Kris Howard, Leslie Townsell, Kaylee Arnold, and Jaida Elcock, this week represents an opportunity for community building and improved representation.

There are few Black folks in ecology and even fewer in marine ecology, says Arnold, a science communicator and disease ecologist. The network that Ive gained through organizing this week is phenomenal. Meeting other Black marine scientists and showing that to the world, especially young Black folks, is a way to say we exist, were here. We have a full day dedicated to young kids, which is unique and exciting.

The organizers hope that the week will help normalize Black folks doing marine research, inspire younger generations, and remind everyone to check their preconceived notions.

"When I say I study sharks people seem concerned about my swimming or my hair, [and] sometimes respond with 'Oh, thats super interesting'... I dont know if that's because it's unusual for people to study sharks or because Im Black and I study sharks, recalls Elcock, an elasmobranch movement ecologist, science communicator, and co-founder of Minorities in Shark Science. Science is for everybody. People say there isn't diversity because [Black] people arent interested... thats clearly not true theres a whole week dedicated [to it]."

Discussion this week will address the fact that exclusion, not lack of interest, led to todays lack of representation. Centuries of segregation and underinvestment in Black neighborhood pools led to, and are perpetuated by, these incorrect and harmful ideas.

My grandparents and my mom said there were just no pools for her to go to... I had a very different experience. Despite people trying to push us out of the water and science, we persevered, and now we get to break down those stereotypes, notes Arnold.

Black in Marine Science Week is here to do just that, showcasing organizers and participants from every imaginable marine science niche, all shaping how society views the oceans and its inhabitants.

There's more Black folks than even we know and are showcasing. I hope that if the media picks up on the number of us as well, and has better representation. Seminar series are extremely white, and now you have a resource of people you can invite instead, emphasizes Arnold, pointing to the necessity of non-Black marine scientists to step up and ensure representation continues beyond this joyous and educational week.

At 14.6% CAGR, Cell Banking Outsourcing Market 2020 Industry Analysis of Current Trends and Opportun - PharmiWeb.com

Skin Stem Cells Comments Off on At 14.6% CAGR, Cell Banking Outsourcing Market 2020 Industry Analysis of Current Trends and Opportun – PharmiWeb.com | December 21st, 2020

Launched in 2013, cruelty-free skincare brand Drunk Elephant has captured the attention of beauty experts, brands, and a strong customer following.

The company, founded by former stay-at-home mom Tiffany Masterson, is one of the fastest-growing skin care brands in the industry. According to Fashionista, this is largely thanks to its philosophy. Masterson is a believer in clean beauty, an ethos thats reflected in Drunk Elephants product line-up. Speaking to how the company came to be, Masterson said, I came up with these criteria: It has to be nontoxic or low-hazard and it has to be bioavailable, meaning able to get into your skin.

As such, all Drunk Elephant products are formulated without what Masterson deemed the Suspicious Six, ingredients that she believed her company could do without: essential oils, silicones, sodium lauryl sulfate aka SLS, drying alcohols, silicones, chemical screens, and fragrances and dyes. When it comes to ingredients, Drunk Elephant goes by the philosophy of If theres any DOUBT, its OUT.

I determined that the six ingredients I wanted to avoid, which I realized were largely there [in competitors products] for marketing, Masterson explained. Silicones make a product feel better; dyes make a product look better; essential oils and fragrance make a product smell better; SLS is a cleansing agent that penetrates your skin and irritates and strips it.

She wanted her brand to be as clean and non-irritating as possible. She even helped formulate the products herself: We went through, ingredient by ingredient, and we swapped out a couple that canceled each other out or that did the same thing, but the resulting ingredient decks were very similar to the ones I first wrote down for every product.

For Masterson, it was a perfect storm of her desire to make a clean beauty brand and evolving consumer shopping habits. Consumer mistrust in companies is on the rise, but for good reason. Last July, Johnson & Johnson was told to pay $4.7 billion to families who claimed that using its talcum powder products caused their ovarian cancer.

While natural and clean beauty are on the rise, Vox points out that the terms are not regulated by the FDA nor the Federal Trade Commission. This means that any company can use the terms for their products and define it as they wish. Clean beauty is still finding favor with consumers its a trend thats been highlighted by Whole Foods Market. People are also becoming concerned over animal ingredients in skincare and makeup, which has helped lead to the rise of vegan beauty, according to The New York Times.

But Drunk Elephants ingredients list shows that Masterson takes her all-natural ethos seriously. In addition to being clean, all products are made in the US.

The company has also resonated with customers Masterson hasnt done any traditional marketing or influencer partnerships. But, she was able to build her brand to the point where she landed in Sephora the TLC Sukari Babyfacial was actually one of the stores top-selling products of 2017.

The Definitive Guide to All Things Vegan By Drunk Elephant - LIVEKINDLY

Skin Stem Cells Comments Off on The Definitive Guide to All Things Vegan By Drunk Elephant – LIVEKINDLY | December 21st, 2020

Autologous bone marrow mononuclear cell (BMMNC) transplantation has been widely studied in recent years. The fresh cell cocktail in BMMNCs, without going through the in vitro culture process, helps to establish a stable microenvironment for osteogenesis, and each cell type may play a unique role in bone regeneration. Our study compared the efficacy of concentrated fresh BMMNCs and cultured bone marrow-derived mesenchymal stem cells (BMSCs) in Beagle dogs for the first time. Fifteen-millimeter segmental bone defects were created in the animals tibia bones. In BMMNCs group, the defects were repaired with concentrated fresh BMMNCs combined with -TCP (n = 5); in cultured BMSC group, with in vitro cultured and osteo-induced BMSCs combined with -TCP (n = 5); in scaffold-only group, with a -TCP graft alone (n = 5); and in blank group, nothing was grafted (n = 3). The healing process was monitored by X-rays and single photon emission computed tomography. The animals were sacrificed 12months after surgery and their tibias were harvested and analyzed by microcomputed tomography and hard tissue histology. Moreover, the microstructure, chemical components, and microbiomechanical properties of the regenerated bone tissue were explored by multiphoton microscopy, Raman spectroscopy and nanoindentation. The results showed that BMMNCs group promoted much more bone regeneration than cultured BMSC group. The grafts in BMMNCs group were better mineralized, and they had collagen arrangement and microbiomechanical properties similar to the contralateral native tibia bone. These results indicate that concentrated fresh bone marrow mononuclear cells may be superior to in vitro expanded stem cells in segmental bone defect repair. 2020 The Authors.

One of the astonishing aspects of the human response to the COVID-19 pandemic has been how quickly scientists pivoted to studying every facet of the virus in order to mitigate the loss of life and plan for a return to normalcy. At the same time, a lot of non-coronavirus research ground to a near halt.

With research labs and offices shuttered for all but essential workers, many scientists were stuck at home, their fieldwork and meetings canceled and planned experiments kicked down the road as they struggled to figure out how to keep their research programs going. Many took the opportunity to catch up on writing grants and papers; some in between caring for kids came up with strategic workarounds to keep the scientific juices flowing.

To gauge how researchers in different fields are managing,Knowable Magazine spoke with an array of scientists and technical staff among them a specialist keeping alive genetically important strains of fruit flies, the maintenance chief of an astronomical observatory working to keep telescopes safe and on standby during the lockdown, and a paediatrician struggling to manage clinical trials for a rare genetic disease. Here are a few slices of scientific life during the pandemic.

Agnieszka Czechowicz, Stanford University School of Medicine

Czechowicz is a paediatrician in Stanfords division of stem cell transplantation and regenerative medicine, where she manages a research group that develops new therapies and conducts clinical trials on rare genetic diseases.

Agnieszka Czechowiczs father suffers from severe Parkinsons disease. The coronavirus pandemic forced him to remain indoors and away from people, robbing him of the physical conditioning and social interactions he needs to cope with his disease. A recent fall left him in the hospital, bringing the additional worry that he might contract COVID-19 there and isolating him further.

For Czechowicz, his situation brought into sharp relief the challenges the coronavirus has forced upon those carrying out clinical trials, including those she is running, which involve patients traveling to hospitals around the country. Would I have him travel to any clinical site right now for a new Parkinsons treatment? she says. Absolutely not.

The pandemic forced Czechowicz to halt clinical trials she oversees for a rare genetic disease of children called Fanconi anAemia, a condition that impairs the bodys ability to repair damaged DNA and often leads to bone marrow failure and cancer. The treatment Czechowicz and colleagues are testing involves extracting blood-forming stem cells from the patients bone marrow, inserting a healthy copy of a missing or malfunctioning gene and then reinfusing those cells back into the patient.

Every aspect of what I do is massively impacted by the pandemic, Czechowicz says. One of her early-stage clinical trials involves testing the safety of the therapy. But during the initial shutdown which started in mid-March and lasted for two months her patients could not readily travel to Stanford for the necessary follow-up visits, and remote monitoring was difficult.

Theres special blood testing and bone marrow testing that we need to do. In particular, its critical to get the samples to make sure the patients, for example, arent developing leukAemia, she says. Theres no way to know that without really checking the bone marrow. She had to clear large hurdles to get her patients evaluated.

Another early-stage trial, designed to determine the effectiveness of the therapy, also had to stop enrolling new patients. Because speed is important when it comes to treating Fanconi anaemia the children are likely losing stem cells all the time any delay in treatment can be a source of great anxiety for their parents. Czechowicz had to explain to them why the trials were temporarily halted. It was really challenging to have these discussions with the families, she says.

With the easing of travel and workplace restrictions, the families began traveling to Stanford in June but with infections back on the rise, many families are becoming hesitant again, says Czechowicz. Fortunately, her trials are small, so she can guide each family through the process of safely resuming the trials and continuing with follow-up. Her own team also has to follow strict safety protocols. For example, even though her lab has 10 members, only two can be in the lab at any one time, and only one parent is allowed into the clinic with the child.

Not all clinical trials can pay such close attention to individual patients. Large trials with hundreds of patients can involve multiple sites and require much more monitoring, so resuming those remains difficult. Also, restrictions on working full bore are slowing the pipeline for new therapies. The impact of that, were not going to see for many years to come, Czechowicz says.

Abolhassan Jawahery, University of Maryland, College Park

Jawahery is a particle physicist and a member of LHCb, one of the main experiments at the Large Hadron Collider (LHC) at CERN, the particle physics laboratory near Geneva.

In December 2018, well before the coronavirus pandemic began, the LHC shut down for upgrades. Housed in a 27-kilometre-long tunnel about 100 meters underground, the LHC accelerates two beams of protons, one clockwise and one counterclockwise, and makes them collide head-on at four locations. There, four gigantic subterranean detectors ATLAS, CMS, LHCb and ALICE sift through the debris of particles created by the collisions, looking for evidence of new physics. (For example, ATLAS and CMS found the Higgs boson, the fundamental particle of the Higgs field, which gives all elementary particles their mass.)

For its next set of experiments, which aim to probe the properties of subatomic particles with greater precision, the LHC needed to increase the intensity of its proton beams. Consequently, the four detectors needed to be upgraded too, to handle the resultant higher temperatures and increased radiation at the sites of the particle collisions. The work was on track for a restart around May 2021 until the pandemic swept all the scientists careful plans away.

The LHC and its four detectors are each run by a separate collaboration. CERN, which manages the LHC, is hopeful it can restart the collider by February 2022. They think that they can get the accelerator going if there are no more major catastrophic events, says physicist Abolhassan Jawahery. But the impact on the four detectors is less clear.

For the LHCb upgrade, Jawaherys team at the University of Maryland had been working on building about 4,000 extremely sensitive electronic circuit boards. These boards have to be burned in before they can be sent to CERN. We put them in an oven, literally cooking the boards and then running extensive tests in order to get them ready so that we can put them in the accelerator and run them for 10 to 20 years, says Jawahery. And none of that could be done during the pandemic shutdown.

The team resumed its work in June, but with restrictions put in place by the state of Maryland. Jawahery runs two labs, and for months was allowed only two people at a time in one lab and three in the other, making progress extremely slow. Still, his team is fortunate that it does not depend on supplies from countries hit hard by the coronavirus. Other labs werent so lucky. Scientists in Milan, for example, built some electronics and detector components for the LHCb, and a lab at Syracuse University in New York built sensors that relied on shipments from Milan. When Milan was completely closed down at the height of the pandemic, Syracuse, too, stopped working on Milan-dependent components.

For Jawahery the lockdown had a silver lining. The LHCs most recent run had produced about 25 gigabytes of data per second but his team had found little time to analyse any of it before the pandemic. We were complaining that we were spending all our time building the new instrument and the data keeps on coming, he says. When he and his team were locked out of their labs, they turned to their data backlog. We could do actual physics, he says. We are already getting ready to publish some papers.

Gordon Gray, Princeton University

Gray is a professionalDrosophila specialist in the department of molecular biology.

Gordon Gray has been called the chef de cuisine of Princetons fly kitchen, where he has been feeding flies for 46 years. He concocts meals for millions of fruit flies, at least 150 litres each week. When the pandemic hit in March and universities around the world shut down, Princeton deemed Grays work an essential service: The Drosophilafruit flies could not be allowed to die off.

Princetons flies include mutant and transgenic strains everything from ones that allow researchers to study the genes that influence normal development of a fly embryos organs, to those that have cancer-causing mutations. If the flies starved, researchers would need months or years to recreate these strains, says Princeton molecular biologist Elizabeth Gavis. And often, as techniques in molecular biology improve, the biologists reexamine flies they had studied earlier to get a more fine-grained understanding, making it worthwhile to preserve the strains.

Normally, if a lab had to shut down, researchers would send their flies to stock centres, such as one at Bowling Green State University in Ohio, that preserve the flies as part of their genetic library. But the stock centres couldnt handle Princetons flies, so Gray found himself on his own. Its basically catch as catch can with regards to the various labs here, just to keep things operational, he says.

For months, university pandemic restrictions have allowed only one person to be in Grays kitchen at a time. This has caused problems. Before the pandemic began, Gray, who is in his late 60s, had started training someone as a backup. But because of the one-person restriction, Gray and his trainee havent been able to work together. Gray envisions doing so soon, while wearing masks, keeping nearly 12 feet apart and communicating using hand signals.

To whip up a batch of fly food, or media, Gray uses a 50-litre steel cauldron, to which is attached a mixer that looks like an outboard motor. Gray fills the cauldron with water and adds agar, sugars, yeasts, salts and cornmeal, then brings it to a boil, all the while stirring watchfully. You dont want it to boil over, because when it does you wind up with a gigantic pancake on the floor, which you have to scoop up immediately because it gels, he says. Once the suspension cools to the right temperature, Gray adds an acid to inhibit mould, then dispenses precise amounts of the media into bottles and vials.

Even before the pandemic, Grays kitchen was isolated, to keep errant fruit flies from contaminating the pristine media. But at least he could work regular hours, because he knew the rhythms of the 10 or so fly labs he cooked for. That has changed. Labs, restricted to two occupants at a time, are now working seven days a week on rotating shifts. Gray comes in to work at all hours, because he cannot predict when each batch of fly food will run out and hell need to cook more.

He tries to work mostly at night to avoid coming into contact with others. But he still worries for his health, given his asthma and age-related risk. The relentless pandemic is taking a toll. Its exhausting, he says. It doesnt help not knowing when we will return to a sense of normalcy.

Celeste Kidd, University of California, Berkeley

Kidd is a child developmental psychologist who uses behavioural tests and computational methods to understand how children acquire knowledge.

When UC Berkeley locked down in March, Celeste Kidd found herself closeted at home, dealing simultaneously with virtual meetings and her three-year-old son. During the early days of the pandemic, Kidd kept a supply of treats handy, and when her toddler came up to her during a meeting shed sneak him some under the desk. But she hadnt accounted for how long the pandemic would last. It turns out thats not a good strategy, long term, she says. I was very literally rewarding him for bad behaviour.

Kidds son soon learned that acting up during her meetings meant more candy. I knew that would happen. I did it anyway because I didnt have the bandwidth to come up with a better solution, she says. But Kidd knew from her own research that children are also extremely flexible and can unlearn behaviours. Eventually, she had a chat with her son. First, she admitted to him that she had made a mistake by giving him candy when he disrupted her meetings, and that was bad of her. Then she brought in new rules: no candy for misbehaving and misbehaviour could even mean no treats for the rest of day. We had some meltdown moments, says Kidd. But he gets it now and he doesnt do those things.

Her son may be the only child Kidd gets to interact with during the pandemic. Thats a huge loss for her research, because the bulk of her work focuses on young children. In normal times, families would bring their children to her lab, where her research team would track their gaze as they watched videos. In one study, for example, infants about seven to nine months old would look away (demonstrating lack of interest) when the events in the video were either too complex or too simple, suggesting that infants use their cognitive resources for stimuli that have just the right amount of information.

Such work, of course, requires the presence of parent, child and researchers, all in the same room. None of that is going to happen anytime soon, she says. Those families are not going to feel comfortable coming in for a while.

Kidd is also concerned about the impact of the pandemic on younger scientists. One of her undergraduate students had spent six months working on a study aimed at exploring the complexity of kids play patterns using physical objects and their relation to working memory and other cognitive resources. The university had approved the protocol, but shelter-in-place orders went into effect the week the first child was to come for the experiment. I feel so bad for her as a young scientist, to have done all this hard work and then right when you get to the fun part, which is collecting the data and finding out if her ideas have lasting merit, she doesnt get to do that part, Kidd says.

The situation might be even worse for grad students and postdocs. All of them are experiencing a big blow to morale in general, because there is so much uncertainty about what the future holds, she says. University budget cuts mean fewer slots for graduate students and fewer jobs for postdocs. Its very hard to stay motivated and get things done when youre not sure if there will be a payoff in the future, says Kidd. Thats literally a study that we ran in the lab so were all acutely aware of it.

Maxime Boccas, ESO Paranal Observatory

Boccas is the head of maintenance, support and engineering at the European Southern Observatorys Paranal Observatory in Chile.

When the massive domes of the Very Large Telescope, a constellation of four 8-meter-class telescopes atop Mount Paranal in Chiles Atacama Desert, open to the night sky each evening and the telescopes get ready for observations, its like a dragon waking up.

When the pandemic hit in March, the dragon on Mount Paranal closed its eyes to the cosmos and slept the first shutdown in its 20-year history, which included a major earthquake in 2010 that paralyzed much of the rest of Chile. For those who had to leave Paranal, it was like being sent away from home. We spend 40% of our life here, says Maxime Boccas, who oversaw the process of ensuring an orderly shutdown of the sites scientific and technical facilities. We work and sleep here, and we stay here eight days in a row. Some of Boccass colleagues have been doing that for 20 to 25 years. Leaving Paranal was like leaving their second home. That was a weird feeling.

The skeleton staff just 20 of the normal 150 or so people remained on site kept the observatory safe, ensuring that essential systems continued working: computers that astronomers were accessing remotely, the fire detection system and the earthquake protection system essential for protecting the 8-meter-wide primary mirrors from Chiles frequent quakes. The mirrors will likely never be made again, says Boccas. All the factories that cast and polished them are dismantled. If we lost a mirror, it would take between 5 and 10 years to build up the factory again and fabricate it. So each mirror has an airbag a tube that inflates around it when the system detects tremors and other protections.

During the shutdown, astronomers kept their fingers crossed. They were anxious that no big thing, like a supernova in our galaxy, would explode, Boccas says. The heavens have been quiet, but the six-month shutdown harmed research that involves continuously monitoring the same patch of the sky for transient phenomena such as gamma ray bursts. It creates a hole in their science program, says Boccas.

The observatory began a slow return to normalcy on September 9. Boccas is overseeing the reawakening of each telescope, one at a time. The staff still less than full strength is now working in shifts that have doubled from 8 to 15 days to limit the amount of travel to and from the site. The four large telescopes are now up and running again, and Boccas hopes they will be back to working together as one by the end of January.

Boccas, his crew and a few lucky astronomers are glad to be back at Paranal. It really feels like a family and I think everyone has noticed that, he says. Even in the kitchen, they have to cook for 30 people instead of 150, so the quality of the food is different, its slightly better.

But even as people return to the observatory, Boccas worries about long-term effects of the shutdown. Given the reduced staff, he has had to cut down on the frequency of preventive maintenance tasks, such as changing belts and lubricating motors, potentially shortening the lifetime of some components. We will not know until six months, a year or three years from now, he says.

How Researchers Are Making Do in the Time of COVID-19 - The Wire Science

Bone Marrow Stem Cells Comments Off on How Researchers Are Making Do in the Time of COVID-19 – The Wire Science | December 21st, 2020

Problems soon after transplant

Many of the problems that can happen shortly after the transplant come from having the bone marrow wiped out by medicines or radiation just before the transplant. Others may be side effects of the conditioning treatments themselves.

Your transplant team can help you cope with side effects. Some can be prevented, and most can be treated to help you feel better.This is not a complete list and you should tell your doctor or transplant team about any problems you have or changes you notice. Some of these problems can be life-threatening, so its important to be able to reach your doctor or transplant team at night, on weekends, and during holidays. Ask for their after hours contact numbers to makesure you will be able to do this.

Mucositis (inflammation or sores in the mouth) is a short-term side effect that can happen with chemo and radiation. It usually gets better within a few weeks after treatment, but it can make it very painful to eat and drink.

Good nutrition is important for people with cancer. If mouth pain or sores make it hard to eat or swallow, your transplant team can help you develop a plan to manage your symptoms.

Because chemotherapy drugs can cause severe nausea and vomiting, doctors often give anti-nausea medicines at the same time as chemo to try to prevent it. As much as possible, the goal is to prevent nausea and vomiting, because its easier to prevent it than it is to stop it once it starts. Preventive treatment should start before chemo is given and should continue for as long as the chemo is likely to cause vomiting, which can be up to 7 to 10 days after the last dose.

No one drug can prevent or control chemo-related nausea and vomiting 100% of the time. In many cases, two or more medicines are used. Youll need to tell your transplant team how well the medicines are controlling your nausea and vomiting. If they arent working, they will need to be changed.

For at least the first 6 weeks after transplant, until the new stem cells start making white blood cells (engraftment), you can easily get serious infections. Bacterial infections are most common during this time, but viral infections that were controlled by your immune system can become active again. Fungal infections can also be an issue. And even infections that cause only mild symptoms in people with normal immune systems can be quite dangerous for you. This is because right after the transplant you don't have many white blood cells that are working well, and they are the primary immune cells that fight off infections.

You may be given antibiotics to try to prevent infections until your blood counts reach a certain level. For instance, pneumocystis pneumonia (often called PCP) is a common infection thats easy to catch. Even though the germ doesnt harm people with normal immune systems, for others it can cause fever, cough, and serious breathing problems. Antibiotics are often used to keep transplant patients from getting this.

Your doctor may check you before the transplant for signs of certain infections that may become active after transplant, and give you special medicines to keep those germs under control. For example, the virus called CMV (cytomegalovirus) is a common infection that many adults have or had in the past. Adults with healthy immune systems may not have any symptoms because their immune system can keep the virus under control. But, CMV can be a cause of serious pneumonia in people who have had transplants, because the transplant lowers the amount of white blood cells they have. Pneumonia from CMVmainly happens to people who were already infected with CMV, or whose donor had the virus. If neither you nor your donor had CMV, the transplant team might follow special precautions to prevent this infection while you are in the hospital.

After engraftment, the risk of infection is lower, but it still can happen. It can take 6 months to a year after transplant for the immune system to work as well as it should. It can take even longer for patients with graft-versus-host disease (GVHD, see below). It's important to talk to your cancer care team about your risk for infection during this time.

Because of the increased risk, you will be watched closely for signs of infection, such as fever, cough, shortness of breath, or diarrhea. Your doctor may check your blood often, and extra precautions will be needed to keep you from being exposed to germs. While in the hospital, everyone who enters your room must wash their hands well. They may also wear gowns, shoe coverings, gloves, and masks.

Since flowers and plants can carry bacteria and fungi, theyre not allowed in your room. For the same reason, you may be told not to eat certain fresh fruits and vegetables. All your food must be well cooked and handled very carefully by you and family members. You might need to avoid certain foods for a while.

You may also be told to avoid contact with soil, feces (stool, both human and animal), aquariums, reptiles, and exotic pets. Your team may tell you to avoid being near disturbed soil, bird droppings, or mold. You will need to wash your hands after touching pets. Your family may need to move the cats litter box away from places you eat or spend your time. Also, you should not clean pet cages or litter boxes during this time. Instead, give this task to a family member or friend.

Your transplant team will tell you and your family in detail about the precautions you need to follow. There are many viruses, bacteria, and fungi that can cause infection after your transplant. You may be at risk for some more than others.

Despite all these precautions, patients often develop fevers, one of the first signs of infection. In fact, sometimes fever is the only sign of infection, so it's very important to contact your cancer care team if you have one or if you have any other signs of infection. You'll probably be asked to take your temperature by mouth every day or twice a day for a while. And your cancer care team will let you know when you should call in your temperature to them. If you get a fever, tests will be done to look for possible causes of the infection (chest x-rays, urine tests, and blood cultures) and antibiotics will be started.

After transplant, youre at risk for bleeding because the conditioning treatment destroys your bodys ability to make platelets. Platelets are the blood cells that help blood to clot. While you wait for your transplanted stem cells to start working, your transplant team may have you follow special precautions to avoid injury and bleeding.

Platelet counts are low for at least several weeks after transplant. In the meantime, you might notice easy bruising and bleeding, such as nosebleeds and bleeding gums. If your platelet count drops below a certain level, a platelet transfusion may be needed. Youll need to follow precautions until your platelet counts stay at safe levels.

It also takes time for your bone marrow to start making red blood cells, and you might need red blood cell transfusions from time to time as you recover.

For more information on the transfusion process, see Blood Transfusion and Donation.

Pneumonitis is a type of inflammation (swelling) in lung tissue thats most common in the first 100 days after transplant. But some lung problems can happen much later even 2 or more years after transplant.

Pneumonia caused by infection happens more often, but pneumonitis may be caused by radiation, graft-versus-host disease, or chemo rather than germs. Its caused by damage to the areas between the cells of the lungs (called interstitial spaces).

Pneumonitis can be severe, especially if total body irradiation was given with chemo as part of the pre-transplant (conditioning) treatment. Chest x-rays will be taken in the hospital to watch for pneumonitis as well as pneumonia. Some doctors will do breathing tests every few months if you have graft-versus-host disease (see next section).

You should report any shortness of breath or changes in your breathing to your doctor or transplant team right away. There are many other types of lung and breathing problems that also need to be handled quickly.

Graft-versus-host disease (GVHD) can happen in allogeneic transplants when the immune cells from the donor see your body as foreign. (Remember: The recipients immune system has mostly been destroyed by conditioning treatment and cannot fight back, so the new stem cells make up most of the immune system after transplant.) The donor immune cells may attack certain organs, most often the skin, gastrointestinal (GI) tract, and liver. This can change the way the organs work and increase the chances of infection.

GVHD reactions are very common and can range from barely noticeable to life-threatening. Doctors think of GVHD as acute or chronic. Acute GVHD starts soon after transplant and lasts a short time. Chronic GVHD starts later and lasts a long time. A person could have one, both, or neither type of GVHD.

Acute GVHD can happen 10 to 90 days after a transplant, though the average time is around 25 days.

About one-third to one-half of allogeneic transplant recipients will develop acute GVHD. Its less common in younger patients and in those with closer HLA matches between donor and the patient.

The first signs are usually a rash, burning, and redness of the skin on the palms and soles. This can spread over the entire body. Other symptoms can include:

Doctors try to prevent acute GVHD by giving drugs that suppress the immune system, such as steroids (glucocorticoids), methotrexate, cyclosporine, tacrolimus, or certain monoclonal antibodies. These drugs are given before acute GVHD starts and can help prevent serious GVHD. Still, mild GVHD will almost always happen in allogeneic transplant patients. Other drugs are being tested in different combinations for GVHD prevention.

The risk of acute GVHD can also be lowered by removing immune cells called T-cells from the donor stem cells before the transplant. But this can also increase the risk of viral infection, leukemia relapse, and graft failure (which is discussed later). Researchers are looking at new ways to remove only certain cells, called alloactivated T-cells, from donor grafts. This would reduce the severity of GVHD and still let the donor T-cells destroy any cancer cells left.

If acute GVHD does occur, it is most often mild, mainly affecting the skin. But sometimes it can be more serious, or even life-threatening.

Mild cases can often be treated with a steroid drug applied to the skin (topically) as an ointment, cream, or lotion, or with other skin treatments. More serious cases of GVHD might need to be treated with a steroid drug taken as a pill or injected into a vein. If steroids arent effective, other drugs that affect the immune system can be used.

Chronic GVHD

Chronic GVHD can start anywhere from about 90 to 600 days after the stem cell transplant. A rash on the palms of the hands or the soles of the feet is often the earliest sign. The rash can spread and is usually itchy and dry. In severe cases, the skin may blister and peel, like a bad sunburn. A fever may also develop. Other symptoms of chronic GVHD can include:

Chronic GVHD is treated with medicines that suppress the immune system, much like those used for acute GVHD. These drugs can increase your risk of infection for as long as you are treated for GVHD. Most patients with chronic GVHD can stop the immunosuppressive drugs after their symptoms improve.

Hepatic veno-occlusive disease (VOD) is a serious problem in which tiny veins and other blood vessels inside the liver become blocked. Its not common, and it only happens in people with allogeneic transplants, and mainly in those who got the drugs busulfan or melphalan as part of conditioning, or treatment that was given before the transplant.

VOD usually happens within about 3 weeks after transplant. Its more common in older people who had liver problems before the transplant, and in those with acute GVHD. It starts with yellowing skin and eyes, dark urine, tenderness below the right ribs (this is where the liver is), and quick weight gain (mostly from fluid that bloats the belly). It is life-threatening, so early diagnosis of VOD is very important. Researchers continue to find ways to try to measure a person's chances of getting VOD so that treatment can start as soon as possible.

Grafts fail when the body does not accept the new stem cells (the graft). The stem cells that were given do not go into the bone marrow and multiply like they should. Graft failure is more common when the patient and donor are not well matched and when patients get stem cells that have had the T-cells removed. It can also happen in patients who get a low number of stem cells, such as a single umbilical cord unit. Still, its not very common.

Graft failure can lead to serious bleeding and/or infection. Graft failure is suspected in patients whose counts do not start going up within 3 to 4 weeks of a bone marrow or peripheral blood transplant, or within 7 weeks of a cord blood transplant.

Although it can be very upsetting to have this happen, these people can get treated with a second dose of stem cells, if they are available. Grafts rarely fail, but if they do it can result in death.

The type of problems that can happen after a transplant depend on many factors, such as the type of transplant done, the pre-transplant chemo or radiation treatment used, the patients overall health, the patients age when the transplant was done, the length and degree of immune system suppression, and whether chronic graft-versus-host-disease (GVHD) is present and how bad it is. The problems can be caused by the conditioning treatment (the pre-transplant chemotherapy and radiation therapy), especially total body irradiation, or by other drugs used during transplant (such as the drugs that may be needed to suppress the immune system after transplant). Possible long-term risks of transplant include:

The medicines used in transplants can harm the bodys organs, such as the heart, lungs, kidneys, liver, bones/joints, and nervous system. You may need careful follow-up with close monitoring and treatment of the long-term organ problems that the transplant can cause. Some of these, like infertility, should be discussed before the transplant, so you can prepare for them.

Its important to find and quickly treat any long-term problems. Tell your doctor right away if you notice any changes or problems. Physical exams by your doctor, blood work, imaging tests, lung/breathing studies, and other tests will help look for and keep tabs on organ problems.

As transplant methods have improved, more people are living longer and doctors are learning more about the long-term results of stem cell transplant. Researchers continue to look for better ways to care for these survivors to give them the best possible quality of life.

The goal of a stem cell transplant in cancer is to prolong life and, in many cases, even cure the cancer. But in some cases, the cancer comes back (sometimes called relapse or recurrence depending on when it might occur after a transplant). Relapse or recurrence can happen a few months to a few years after transplant. It happens much more rarely 5 or more years after transplant.

If cancer comes back, treatment options are often quite limited. A lot depends on your overall health at that point, and whether the type of cancer you have responds well to drug treatment. Treatment for those who are otherwise healthy and strong may include chemotherapy or targeted therapy. Some patients who have had allogeneic transplants may be helped by getting white blood cells from the same donor (this is called donor lymphocyte infusion) to boost the graft-versus-cancer effect. Sometimes a second transplant is possible. But most of these treatments pose serious risks even to healthier patients, so those who are frail, older, or have chronic health problems are often unable to have them.

Other options may include palliative (comfort) care, or a clinical trial of an investigational treatment. Its important to know what the expected outcome of any further treatment might be, so talk with your doctor about the purpose of the treatment. Be sure you understand the benefits and risks before you decide.

Along with the possibility of the original cancer coming back (relapse) after it was treated with a stem cell transplant, there is also a chance of having a second cancer after transplant. Studies have shown that people who have had allogeneic transplants have a higher risk of second cancer than people who got a different type of stem cell transplant.

A cancer called post-transplant lymphoproliferative disease (PTLD), if it occurs, usually develops within the first year after the transplant. Other conditions and cancers that can happen are solid tumor cancers in different organs, leukemia, and myelodysplastic syndromes. These other conditions, if they occur, tend to develop a few years or longer after the transplant.

Risk factors for developing a second cancer are being studied and may include:

Successfully treating a first cancer gives a second cancer time (and the chance) to develop. No matter what type of cancer is treated, and even without the high doses used for transplant, treatments like radiation and chemo can lead to a second cancer in the future.

Post-transplant lymphoproliferative disorder (PTLD) is an out-of-control growth of lymph cells, actually a type of lymphoma, that can develop after an allogeneic stem cell transplant. Its linked to T-cells (a type of white blood cell that is part of the immune system) and the presence of Epstein-Barr virus (EBV). T-cells normally help rid the body of cells that contain viruses. When the T-cells arent working well, EBV-infected B-lymphocytes (a type of white blood cell) can grow and multiply. Most people are infected with EBV at some time during their lives, but the infection is controlled by a healthy immune system. The pre-transplant treatment given weakens the immune system, allowing the EBV infection to get out of control, which can lead to a PTLD.

Still, PTLD after allogeneic stem cell transplant is fairly rare. It most often develops within 1 to 6 months after allogeneic stem cell transplant, when the immune system is still very weak.

PTLD is life-threatening. It may show up as lymph node swelling, fever, and chills. Theres no one standard treatment, but its often treated by cutting back on immunosuppressant drugs to let the patients immune system fight back. Other treatments include white blood cell (lymphocyte) transfusions to boost the immune response, using drugs like rituximab to kill the B cells, and giving anti-viral drugs to treat the EBV.

Even though PTLD doesnt often happen after transplant, its more likely to occur with less well-matched donors and when strong suppression of the immune system is needed. Studies are being done to identify risk factors for PTLD and look for ways to prevent it in transplant patients who are at risk.

Most people who have stem cell transplants become infertile (unable to have children). This is not caused by the cells that are transplanted, but rather by the high doses of chemo and/or radiation therapy used. These treatments affect both normal and abnormal cells, and often damage reproductive organs.

If having children is important to you, or if you think it might be important in the future, talk to your doctor about ways to protect your fertility before treatment. Your doctor may be able to tell you if a particular treatment will be likely to cause infertility.

After chemo or radiation, some women may find their menstrual periods become irregular or stop completely. This doesnt always mean they cannot get pregnant, so birth control should be used before and after a transplant. The drugs used in transplants can harm a growing fetus.

The drugs used during transplant can also damage sperm, so men should use birth control to avoid starting a pregnancy during and for some time after the transplant process. Transplants may cause temporary or permanent infertility for men as well. Fertility returns in some men, but the timing is unpredictable. Men might consider storing their sperm before having a transplant.

Stem Cell or Bone Marrow Transplant Side Effects

Bone Marrow Stem Cells Comments Off on Stem Cell or Bone Marrow Transplant Side Effects | December 19th, 2020

18 months into the first serious clinical trials of CRISPR gene therapy for sickle cell disease and beta-thalassemiaand all patients are free from symptoms and have not needed blood transfusions.

Sickle cell disease (SCD) can cause a variety of health problems including episodes of severe pain, called vaso-occlusive crises, as well as organ damage and strokes.

Patients with transfusion-dependent thalassemia (TDT) are dependent on blood transfusions from early childhood.

The only available cure for both diseases is a bone marrow transplant from a closely related donor, an option that is not available for the vast majority of patients because of difficulty locating matched donors, the cost, and the risk of complications.

In the studies, the researchers goal is to functionally cure the blood disorders using CRISPR/Cas9 gene-editing by increasing the production of fetal hemoglobin, which produces normal, healthy red blood cells as opposed to the misshapen cells produced by faulty hemoglobin in the bodies of individuals with the disorders.

The clinical trials involve collecting stem cells from the patients. Researchers edit the stem cells using CRISPR-Cas9 and infuse the gene-modified cells into the patients. Patients remain in the hospital for approximately one month following the infusion.

Prior to receiving their modified cells, the seven patients with beta thalassemia required blood transfusions approximately every three to four weeks and the three patients with SCD suffered episodes of severe pain roughly every other month.

All the individuals with beta thalassemia have been transfusion independent since receiving the treatment, a period ranging between two and 18 months.

Similarly, none of the individuals with SCD have experienced vaso-occlusive crises since CTX001 infusion. All patients showed a substantial and sustained increase in the production of fetal hemoglobin.

15 months on, and the first patient to receive the treatment for SCD, Victoria Gray, has even been on a plane for the first time.

Before receiving CRISPR gene therapy, Gray worried that the altitude change would cause an excruciating pain attack while flying. Now she no longer worries about such things.

She told NPR of her trip to Washington, D.C: It was one of those things I was waiting to get a chance to do It was exciting. I had a window. And I got to look out the window and see the clouds and everything.

This December, theNew England Journal of Medicinepublishedthe first peer-reviewed research paperfrom the studyit focuses on Gray and the first TDT patient who was treated with an infusion of billions of edited cells into their body.

There is a great need to find new therapies for beta thalassemia and sickle cell disease, saidHaydar Frangoul, MD,Medical Director of Pediatric Hematology and Oncology at Sarah Cannon Research Institute, HCA Healthcares TriStar Centennial Medical Center. What we have been able to do through this study is a tremendous achievement. By gene editing the patients own stem cells we may have the potential to make this therapy an option for many patients facing these blood diseases.

Because of the precise way CRISPR-Cas9 gene editing works, Dr. Frangoul suggested the technique could potentially cure or ameliorate a variety of diseases that have genetic origins.

As GNN has reported, researchers are already using CRISPR to try and treat cancer, Parkinsons, heart disease, and HIV, as well.

Dr. Faye Yin

Dr. Faye Yin

Melanoma is a serious and life-threatening form of cancer that begins in the skin but can spread rapidly if not treated early. We sat down with board-certified oncologist Dr. Faye Yin, an oncologist at Jersey City Medical Center, to learn more about this disease, its causes and risk factors, and why its important to protect yourself from excessive sun exposure even during the cold winter months.

What are the main risk factors for developing melanoma?

Ultraviolet, or UV, light exposure is the major risk factor. Melanoma is associated with both UVB rays, which are present in sunlight, and UVA rays, which are generated by tanning beds. Other risk factors include the presence of moles on the skin. Most are benign, but those with excessive moles should consult a dermatologist, especially if they observe any changes. Often, a mole will be removed as a precautionary measure. Age is also a risk factor; the older the person, the higher the risk. People with fair skin, freckles, and lighter hair are also more susceptible, which is why melanoma is more common in white and light-skinned people. Other risk factors include family history and the presence of a weakened immune system. Those with xeroderma pigmentosum, or XP, a rare genetic disorder, are particularly at risk because the condition affects the ability of skin cells to repair themselves after UV light exposure.

What should people do if they have any of these risk factors?

As with most risk factors impacting health, there are things you can change, and things you cannot. You cant change your skin color or family history, and you cant avoid getting older. But you can limit your exposure to UV rays. A popular catchphrase that I tell my patients, which has been promoted by the American Cancer Society, is Slip, Slop, Slap, and Wrap. Slip on a shirt, slop on some sunscreen, slap on a hat, and wrap on some sunglasses. I also recommend that people avoid using tanning beds and sun lamps. Teaching children about sun safety is especially important, because they tend to spend more time outdoors and can burn more easily. It is also important for people with risk factors to pay closer attention to their skin. Keep an eye out for abnormal moles or other skin features that appear to be unusual or changing over time, and consult a dermatologist if necessary.

Can sunlight still be dangerous during winter?

Yes whether youre skiing or just going for a walk, it is great to enjoy the sun and being outdoors in the winter, but its just as important to protect yourself from excess sun exposure in winter as it is in summer. Harmful ultraviolet rays are present year-round. They can even filter through dark cloud coverage to reach your skin, increasing your risk of melanoma. Some people may experience a bad sunburn on a winter vacation, especially if they ski in high altitudes, because UV rays are usually more intense in higher regions with a thinner atmosphere. When youre outside, any uncovered areas of your body are exposed to UV rays. So, its important to wear sunscreen even in the winter months.

Is smoking a risk factor for developing melanoma, and if so, is it mostly if youre currently smoking (for instance, what if you smoked for years and stopped?)

As an oncologist, every day I tell my patients: dont smoke! Smoking is a contributing factor for many cancers, and I believe that it also affects overall skin health; I can often look at someones skin and tell whether they smoke. That having been said, we dont have evidence that smoking directly contributes to melanoma. But I always encourage patients not to smoke to stay healthy and minimize their cancer risk.

Why does having a weakened immune system count as a risk factor for melanoma?

Having a weakened immune system increases the risk of melanoma and other cancers. I have worked with many patients whose immune systems have been compromised, either by illness or in some cases due to medical treatment for other conditions. For example, immunosuppressive drugs are used after stem cell and organ transplants, to prevent the body from rejecting the transplant. Certain diseases also compromise the immune system, such as HIV. A weakened immune system increases cancer risk for two reasons. First, because the body has less ability to detect and destroy cancer cells. And secondly, because the body is more susceptible to infections that may lead to cancer.

Is gender a risk factor? If so, do we know why?

In the United States, men typically have a higher rate of melanoma than women, though this varies by age. Before age 50, the risk is higher for women, and after age 50, the risk is higher in men. We believe that this discrepancy relates to the fact that men are likely to spend more time in the sun over the course of their lifetimes. I also think that women are more likely to wear sunscreen than men, so this may play a role. In addition, men tend to have thicker skin with less fat beneath it and more collagen, and some research shows that this can make the skin more susceptible to sunlight damage. Also, some studies have shown that estrogen, which is more prevalent in women, can increase resistance to melanoma.

Are older people at higher risk for melanoma?

The risk of melanoma increases as you age. The average age for a melanoma diagnosis is age 65. But melanoma is not uncommon even among those younger than age 30. In fact, it is one of the most common cancers in young adults, especially young women. Melanoma is also more common in younger people whose families have a history of melanoma.

How does having a family history of having melanoma impact someone?

Family history is definitely a melanoma risk factor; the risk is higher among those who have one or more first-degree relatives who have had melanoma. About 10 percent of people diagnosed with melanoma have a family history. Families tend to have shared lifestyle habits, such as more frequent sun exposure, and in addition they typically have similar skin types and share certain genetic characteristics. You cant change your skin color or your genes, but you can change some factors. If you know that you are higher risk, and have a family history, pay close attention to your skin. Avoid excessive sunlight and tanning beds, and consult a dermatologist if you have concerns.

Why is UV light exposure a risk factor?

Numerous studies have shown that sun and UV light exposure is a major melanoma risk factor, especially for children and teens. Research shows that early sun exposure can damage the DNA in skin cells. Melanocytes are the cells that produce melanin, which gives skin its pigmentation, and damaging these cells can start the path to melanoma. Melanoma commonly occurs on the thighs of women, and on the trunks of men, as well as on arms and faces, which are the areas that most often receive chronic sun exposure in young people. In addition to limiting UV light exposure, people should also examine their own skin at least monthly, especially if there are high risk factors. If you see something unusual, such as a large mole or a spot youre not sure about, I will often encourage patients to take a photograph of it. You might not notice small changes over time because you get accustomed to them. But if you take a picture of a spot on your skin and compare it a month or a few months later, and you see a change, you should see a dermatologist.

Most treatment for heart failure can only slow it down or ease your symptoms. Soon, it may be possible to fix what causes it. Doctors are testing whether stem cells can repair or replace damaged heart cells.

Stem cells can grow into many different kinds of cells. You have them in organs and tissues all over your body. They divide to replace worn-out or damaged cells, and to become new stem cells.

In the lab, scientists have turned stem cells into ones that make up blood vessel walls and linings, and into actual beating heart cells. Now theyre trying to translate that into a treatment.

Scientists have zeroed in on a few specific kinds of cells that may be helpful:

Bone marrow mononuclear cells: A mixture of cells that comes from your own bone marrow.

Cardiac-derived stem cells: Ones found in heart tissue.

Mesenchymal stromal cells: They're usually taken from bone marrow, fat, or umbilical cord blood.

Proangiogenic progenitor cells: These are in blood and bone marrow.

It's not approved to treat heart failure, yet. You can get it through a clinical trial. Thats when the research moves from the lab to the hospital to see if a treatment is safe and if it works.

If you want to try stem cell therapy, ask your doctors if there are studies that may be a good fit for you. The National Library of Medicine has a website that helps you search for all kinds of clinical trials.

Not all experimental treatments are part of a clinical trial, so make sure you understand what youre signing up for. If its a legitimate study, you shouldnt have to pay for treatment or follow-ups.

Most people testing stem cell therapy for heart failure get one treatment. Then theyre checked every few months for a year or more.

Not everyone in a trial actually gets stem cells. Researchers need to compare the results of the new treatment against what happens with a group of people who dont get it.

Doctors are testing several different methods of giving people stem cells:

Intramyocardial injection: Cells go right into the heart muscle, usually during another procedure like open-heart surgery, bypass surgery, or implanting a pacemaker.

Intracoronary infusion: A catheter puts cells into your coronary artery. It goes into a large blood vessel in your groin and threaded through your heart.

Intravenously: Cells go right into the bloodstream through a needle placed in a vein.

With any of these methods, most stem cells leave the body quickly. Researchers are looking for better ways to make them stick. One possibility is growing them into a patch that goes directly to the damaged part of the heart.

Theres no way to fix heart damage that leads to heart failure. Stem cell therapy could change that. Still, its too early to call any treatment a success. The studies done so far have been too small. They've also used very different methods.

But it does look like stem cells could help repair heart tissue. In most studies, people who got them were less likely to die or go to the hospital during the study. Their hearts worked better and their quality of life was better than for people who didnt get them.

It isnt clear how stem cells help. Doctors hope clinical trials and research will help them discover that. They're also hoping to answer many other questions, including:

If you are interested in joining a trial, talk to your doctor.

Stem Cell Therapy for Heart Failure Treatment

Cardiac Stem Cells Comments Off on Stem Cell Therapy for Heart Failure Treatment | December 17th, 2020

TAMPA, Fla. While health officials and lawmakers continue trying to steer young people away from vaping, the wide variety of enticing flavors added to these products make that a tough task. Although most of the worry over vaping comes from the risk of addiction, lung damage, and threat of switching to conventional cigarettes, a new study finds the flavoring chemicals these products use may be just as harmful as anything else. Researchers from the University of South Florida Health say vaporized flavoring molecules are toxic to the heart and damage the organs ability to beat correctly.

While other studies find that vaping is generally less harmful than smoking traditional tobacco products, the nicotine and other chemicals in e-cigarettes still damages the heart and lungs. Until now however, researchers say the impact of flavoring additives inhaled into the bloodstream remained unclear.

The flavored electronic nicotine delivery systems widely popular among teens and young adults are not harm-free, says principal investigator Dr. Sami Noujaim in a university release. Altogether, our findings in the cells and mice indicate that vaping does interfere with the normal functioning of the heart and can potentially lead to cardiac rhythm disturbances.

Dr. Noujaims study is one of the first to investigate the cardiotoxic effects of flavoring chemicals added to the e-liquids in electronic nicotine delivery systems (ENDS). ENDS include a variety of different vaping products like vape pens, mods, and pods.

Researchers define vaping as inhaling aerosols (tiny droplets) which e-cigarettes create by heating liquid nicotine and solvents like propylene glycol and vegetable glycerin. A vaping devices battery-powered heater converts this liquid into a smoke-like mix, or vapor.

The study tested how three popular e-liquid flavors fruit, cinnamon, and vanilla custard affect cardiac muscle cells (HL-1) of mice. After being exposed to e-vapor in a lab dish, the results reveal all three flavors are toxic to HL-1 cells.

The USF team also examined what happens to cardiac cells grown from human stem cells that are exposed to three types of e-vapors. The first substance containing only solvents interfered with the cells electrical activity and beating rate. The second substance, containing both nicotine and solvents, proved to be even more toxic to the heart cells.

The third substance however, containing nicotine, solvents, and vanilla custard flavoring, caused the most damage to the heart and its ability to spontaneously beat correctly. Researchers also determined that vanilla custard flavoring is the most toxic of the varieties tested.

This experiment told us that the flavoring chemicals added to vaping devices can increase harm beyond what the nicotine alone can do, Dr. Noujaim says.

The study also tested flavored vapings impact on live mice. Researchers implanted each subject with a tiny electrocardiogram device before exposing them to 60 puffs of vanilla-flavored e-vapor five days a week for 10 weeks.

Study authors looked at how this exposure impacted heart rate variability (HRV), which is the change in time intervals between successive heartbeats. The results show that HRV decreased in vaping mice compared to those only exposed to puffs of clean air.

The USF team finds vaping interferes with normal HRV by disrupting the autonomic nervous system and its control over heart rate. Mice exposed to flavored vaping are also more prone to a dangerous heart rhythm problem called ventricular tachycardia.

Researchers say they still have to confirm these results in humans. Dr. Noujaim urges policymakers to continue looking at the growing evidence that vaping is not a particularly safer alternative to smoking.

Our research matters because regulation of the vaping industry is a work in progress, Dr. Noujaim explains. The FDA needs input from the scientific community about all the possible risks of vaping in order to effectively regulate electronic nicotine delivery systems and protect the publics health. At USF Health, in particular, we will continue to examine how vaping may adversely affect cardiac health.

The study appears in the American Journal of Physiology- Heart and Circulatory Physiology.

Stem cell transplants from bone marrow or blood offer lifesaving treatment. They are also taxing physically and emotionally.

Its important to know:

What are stem cells?

Blood cells are short-lived and must be replaced. Blood-forming stem cells (hematopoietic cells)divide and multiply. Some mature into one of three blood cell types:

Stem cells are found in bone marrow, in the bloodstream and in umbilical cord blood. In the bloodstream, they are called peripheral blood stem cells (PBSCs). Stem cells from any of these sources can be used in transplants.

What are stem cell transplants?

With a stem cell transplant, a doctor gives you healthy replacementcells that help you fight infection and disease. Doctors most often use stem cell transplants to treat blood disorders and blood cancers that:

A transplant is like a blood transfusion. There are three types:

How stem cell transplants work

Youundergo a process called conditioning. Chemotherapy, radiation therapy or both are used todestroycancer cells and healthy cells that could keep your body from accepting transplanted cells.

New cells are added toyour bloodstream with an IV. The cellscollect in your bone marrow, where they produce new blood cells. Because conditioning leaves your immune system weak, you will need two to three weeks of monitoring.

Who gets a transplant?

At the OHSU Knight Cancer Institute, we consider every person with blood cancer for a stem cell transplant. It might be right for you if your cancer didnt respond to other treatment or if your cancer came back after treatment.

Our providers meet at weekly gatherings called tumor boards to develop the best treatment options for each patient.

Our team considers factors such as your:

Youll want to consider:

What disorders do transplants treat?

Bone marrow/stem cell transplants may be an option to treat:

Leukemias:

Lymphomas:

Other blood cancers and blood disorders:

Other conditions:

Types of stem cell transplants

There are two main types of transplants, each with risks and benefits. OHSU is the only place in Oregon that offers allogeneic transplants.

Autologous transplant

What is it?This type uses your own stem cells. This eliminates the risk of your body rejecting donor cells or of donor cells attacking your body. A relapse may be more likely, though, because you wont have healthy donated cells to attack any diseased cells that remain after conditioning.

How it works:Your care team collects bone marrow using a hollow needle or draws blood and uses a machine to separate out stem cells. The stem cells are frozen. After the conditioning process, the cells are transplanted using anIV drip.

Allogeneic transplant

What is it? We use cells from a donor. Sometimes your own cells are too diseased to collect and reuse. Donor cells are more aggressive in killing any diseased cells left after conditioning. The risk is that they may aggressively target your healthy cells as well, a complication called graft-versus-host disease.

How it works: After the conditioning process, we transplant healthy donor cells using anIV drip. The donor cells help your body rebuild your immune system. A donor can be a relative or someone else whose marrow matches yours.

Allogeneic transplants include:

Bone marrow donors

OHSU has participated in Be The Match: The National Marrow Donor Program since 1996. This program helps people find a lifesaving marrow or PBSC donor. Donors must meet medical guidelinesand should expect to spend 20 to 30 hours in treatment over four to six weeks.

Testing:To find the closest match, doctors will test your blood and a potential donors blood to find their human leukocyte antigen (HLA) type.

HLA markers:Everyone inherits a set of HLA markers from their parents. These markers, contained in almost all of your cells, tell your body which cells belong to you. The more matching markers you and a donor have, the better your chances of a successful transplant. OHSU has success with haploidentical transplants, however, in which as few as half the markers match.

Transplant risks

As with any procedure, transplants involve risks. Your care team will discuss these with you in detail.

Infection: Chemotherapy and radiation therapy weaken your immune system. You are at high risk of infection for up to six weeks until your new cells make healthy blood cells. Your care team will keep you in a safe environment with protection against airborne germs. You will receive safety instructions for going home.

Low platelets:Your platelets will be low for three or more weeks. We will take great care to help you avoid injury or bleeding. Some patients may need a blood transfusion to replace platelets.

Pain:Mouth or throat pain is a common side effect of chemotherapy and radiation therapy. It may cause difficulty eating or swallowing for a few weeks.

Graft failure: Transplant (graft) failure occurs when the body rejects the donor cells. This is rare with stem cell transplants but more common when HLA types are poorly matched.

Graft-versus-host disease:This happens when transplanted cells from the donor attack the recipients tissue and organs. This common complication can range from mild to life-threatening.

Organ damage:Chemotherapy and radiation can leave lasting damage. Well monitor you closely for signs of any problem.

Infertility:The chemotherapy and radiation therapy used before transplants typically result in infertility. OHSU fertility expertscan offer options to preserve your ability to have children before treatment begins.

Physical and emotional effects

Transplants are difficult. They require weeks in or near the hospital, away from work and regular activities. Our cancer social workerscan provide support to you and your family before, during and after treatment:

Physio Logic Brings Cutting-edge Regenerative Treatments for Sport Injuries and Arthritis to New York City - PRNewswire

Bone Marrow Stem Cells Comments Off on Physio Logic Brings Cutting-edge Regenerative Treatments for Sport Injuries and Arthritis to New York City – PRNewswire | December 17th, 2020

PHILADELPHIA, Dec. 17, 2020 /PRNewswire/ --Immunotherapies, such as checkpoint inhibitor drugs, have made worlds of difference for the treatment of cancer. Most clinicians and scientists understand these drugs act on what's known as the adaptive immune system, the T cells and B cells that respond to specific threats to the body.

New research from a team co-led by Penn Dental Medicine's George Hajishengallis suggests that the innate immune system, which responds more generally to bodily invaders, may be an important yet overlooked component of immunotherapy's success.

Their work, published in the journal Cell, found that "training" the innate immune system with -glucan, a compound derived from fungus, inspired the production of innate immune cells, specifically neutrophils, that were programmed to prevent or attack tumors in an animal model.

"The focus in immunotherapy is placed on adaptive immunity, like checkpoint inhibitors inhibit the interaction between cancer cells and T cells," says Hajishengallis. "The innate immune cells, or myeloid cells, have not been considered so important. Yet our work suggests the myeloid cells can play a critical role in regulating tumor behavior."

The current study builds on earlier work by Hajishengallis and a multi-institutional team of collaborators, which showed that trained immunity, elicited through exposure to the fungus-derived compound -glucan, could improve immune recovery after chemotherapy in a mouse model.

In that previous study, the researchers also showed that the "memory" of the innate immune system was held within the bone marrow, in hematopoietic stem cells that serve as precursors of myeloid cells, such as neutrophils, monocytes, and macrophages.

The team next wanted to get at the details of the mechanism by which this memory was encoded. "The fact that -glucan helps you fight tumors doesn't necessarily mean it was through trained immunity," says Hajishengallis.

To confirm that link, the researchers isolated neutrophils from mice that had received the innate immune training via exposure to -glucan and transferred them, along with cells that grow into melanoma tumors, to mice that had not received -glucan. Tumor growth was significantly dampened in animals that received cells from mice that had been trained.

-glucan is already in clinical trials for cancer immunotherapy, but the researchers say this finding suggests a novel mechanism of action with new treatment approaches.

"This is a breakthrough concept that can be therapeutically exploited for cancer immunotherapy in humans," Hajishengallis says, "specifically by transferring neutrophils from -glucan-trained donors to cancer patients who would be recipients."

The stock price of Creative Medical Technology Holdings Inc (OTCMKTS: CELZ) a company that engages in stem cell research and developing applications to treat male sexual dysfunction and related issues increased by 80.77% yesterday as it went from $0.0026 to $0.0047 per share. One of the biggest triggers for the stock price increase is an announcement about the company announcing the successful application of ImmCelz immunotherapy for treatment of stroke.

In an animal model of ischemia stroke, the middle cerebral artery ligation model, administration of ImmCelz resulted in 34% reduction in infarct volume, whereas control bone marrow mesenchymal stem cells reduced infarct volume by 21%. And there were improvements in functional recovery were observed using the Rotarod test.

At 28 days after induction of stroke the animals receiving ImmCelz had superior running time (92% of non-stroke controls) compared to animals that received bone marrow mesenchymal stem cells (73% of non-stroke control). And animals that received saline had a running time that was 50% of non-stroke controls.

KEY QUOTES:

The regenerative potential of immune cells that have been programmed by stem cells is a fascinating and novel area of research. Conceptual advantages of using reprogrammed T cells include higher migratory ability due to smaller size, as well as ability to replicate and potentially formregenerative memory cells.

Dr.Amit Patel, coinventor of ImmCelz

This data, which is covered by our previous filed patents, such as no. 15/987739,Generation of autologous immune modulatory cells for treatment of neurological conditions, demonstrate that immune modulation via this stem cell based method may be a novel and superior way of addressing the$30 billion dollarmarket for stroke therapeutics. The fact that this technology, which has priority back to 2017, is demonstrating such stunning results, motivates us to consider filing an Investigational New Drug Application for use in stroke.

Dr.Thomas Ichim, coinventor of the patent and Chief Scientific Officer of Creative Medical Technology

While stroke historically has been a major area of unmet medical need, the rise in stroke cases , as well as the fact that younger people are increasingly falling victim to stroke, strongly motivates us to accelerate our developmental programs and to continue to explore participation of Big Pharma in this space. We are eager to replicate the existing experiments start compiling the dossier needed to take ImmCelz into humans using the Investigational New Drug Application (IND) route through the FDA.

Today, we take an in-depth look at an intriguing development concern with one product approved and on the market and more importantly a more lucrative candidate that appears on its way to approval in Europe. A full analysis on this Busted IPO follows in the paragraphs below.

Orchard Therapeutics (ORTX) is a London, United Kingdom-based biopharmaceutical company that IPO'd in 2018. The company is focused on developing gene therapies for rare conditions. In 2018, Orchard acquired GSK's rare disease gene therapy portfolio, which originated from a collaboration between GSK and the San Raffaele Telethon Institute for Gene Therapy. The company's unique approach involves inserting a working copy of the missing or malfunctioning gene into a patient's own blood stem cells. This approach circumvents the need for a bone marrow transplant since it leverages blood stem cells intrinsic capacity to self-renew in a patient's bone marrow and produce new blood cells of all types. The company's overarching goal is to permanently correct genetic disorders via a single treatment.

The company does have one approved product called Strimvelis, which is indicated for patients with severe combined immunodeficiency due to adenosine deaminase deficiency for whom no suitable human leukocyte antigen matched related stem cell donor is available; however, the drug has only been approved by the EMA and not the FDA. The company's pipeline is candidate rich, spanning a variety of indications that are compartmentalized into three categories: neurometabolic/neurodegenerative disorders, immunological disorders, and blood disorders. The company has a couple of late-stage candidates. Orchard Therapeutics has a market capitalization of roughly $450 million and trades for approximately $4.50 a share.

Pipeline

OTL-200

OTL-200 is an ex vivo autologous gene therapy in development to treat metachromatic leukodystrophy. The drug uses a modified virus to insert an operational copy of the ARSA gene into a patient's cells. OTL-200 has received rare pediatric disease designation from the FDA. MLD is a rare and deadly inherited disease. The disease is characterized by the accumulation of fats called sulfatides, which causes a breakdown in the protective fatty layer surrounding nerves in the central and peripheral nerve systems. It is estimated that 1 in 40,000 to 1 in 160,000 people have the disease worldwide. OTL-200 was developed in partnership with the San Raffaele Telethon Institute for Gene Therapy.

Source: Company Presentation

On October 16th, the company announced that it received a positive CHMP opinion for the drug, which recommended full marketing authorization for the treatment of early-onset metachromatic leukodystrophy patients in the European Union. The positive opinion will now be reviewed by the European Commission. A final decision is expected by the end of 2020. If approved, the company would be targeting a launch in the first half of 2021.

Furthermore, the company is pursuing a regenerative medicine advanced therapy designation, and it filed an investigational new drug application or IND in the U.S., which was accepted by the FDA on November 19th. Orchard has also applied for Regenerative Medicine Advanced Therapy designation for OTL-200 to help facilitate additional dialogue with the FDA

In addition, within the neurometabolic/neurodegenerative disorders category, it was announced in September that the European Medicines Agency has granted Priority Medicines designation to OTL-203 for the treatment of mucopolysaccharidosis type I. This comes not long after 203 received Orphan Drug designation in the U.S.

Source: Company Presentation

OTL-103

OTL-103 is an ex vivo autologous gene therapy in development to treat Wiskott-Aldrich syndrome. The drug uses a modified virus to insert a working copy of the WAS gene into a patient's cells. WAS is a rare, X-linked, recessive, inherited immune disorder, which is characterized by reoccurring severe infections, autoimmunity, eczema and severe bleeding episodes. The company has received Rare Pediatric Disease designation and Regenerative Medicine Advanced Therapy designation from the FDA. OTL-103 is being developed in partnership with the San Raffaele Telethon Institute for Gene Therapy.

Looking ahead, the company is preparing to file a BLA in the U.S. and an MAA in the EU for OTL-103 in WAS in 2021.

As of September 30th, 2020, Orchard Therapeutics had cash and cash equivalents of $41.1 million compared to $19 million on December 31st, 2019. Research and development expenses for the third quarter were $14.6 million compared to $28.4 million in Q3 of 2019. Selling, general and administrative expenses were $12.9 million in the quarter compared to $14.2 million in the same quarter of 2019. The company did $1.9 million in product revenue for the quarter compared to $1.9 million in Q3 of 2019. Overall, the company reported a net loss of $20.2 million compared to a net loss of $36.7 million in Q3 of 2019. Management stated in the latest quarterly update that it expects its current financial position to cover its anticipated operating and capital expenditure requirements into 2022.

The company is sparsely covered in the United States despite a healthy market cap as our most names in this space domiciled overseas. The most recent recommendation comes from Oppenheimer on September 14th. The firm lowered its price target from $26 a share to $16 a share, but it maintained its overweight rating. The analyst stated that the updated price target reflects a more subdued opinion on the pace of pipeline development for MPS-1 and MPS-IIIA. It reiterated this rating on November 19th.

Both Barclays ($13 price target, down from $15 previously) and Goldman Sachs ($9 price target, down from $13) reiterated Buy ratings on ORTX albeit revising the price targets lower. Finally, on May 22nd, JPMorgan lowered its price target from $26 a share to $17 a share and maintained its overweight rating. The analyst's note did seem upbeat despite the lowered price target in that the analyst thinks that the company's pipeline possesses "broad potential".

Two things prevent Orchard from being considered for a large holding. First, the company looks like it will have to raise additional capital in the very near future. I think the company will raise capital immediately after the next positive news event. Second, overseas biotech concerns don't ever seem to get the attention from analysts or valuation from investors that companies domiciled in the States do. That said, the company has multiple shots on goal and definable potential catalysts on the near-term potential. Add in the possible wildcard of being a potential buyout target at some point, and ORTX would seem worthy of a small "watch item" stake at this time.
