Pittsburgh researcher says potential vaccines are being undermined by misinformation – wausaupilotandreview.com

By Oliver Morrison | Public Source Media

The state of COVID-19 vaccine research is currently in a Catch-22 dilemma, according to Dr. William Klimstra, an associate professor in the Immunology Department at the University of Pittsburgh, who is currently working on a potential vaccine.

The dilemma is this: The reason the development of a vaccine takes so long is that scientists have to be careful the vaccine does no harm in animals first and then in humans, before it even begins to test whether its effective. But at the same time, many Americans are not convinced that a vaccine would be safe and have said they wouldnt take it even if it was developed.

Were in an environment right now where longstanding accepted truths are being challenged through social media, Klimstra said. Its very difficult to fight that kind of stuff.

Experts Urge Caution in Interpreting COVID-19 Antibody Tests – Technology Networks

As stay-at-home orders are lifted around the country and public life begins to return, health experts continue to emphasize the importance of testing for COVID-19 to prevent a second and potentially worse wave of infections.

There are two kinds of COVID-19 tests, and both are critical to controlling this pandemic. Molecular diagnostic tests, first developed in January, detect parts of the COVID-19-causing virus on swabs from peoples noses or throats. Such tests can identify people with active infections, even when they have no symptoms. With widespread and rapid diagnostic testing, people with the virus can be identified quickly and isolated, and anyone who came into contact with them quarantined and tested. Such surveillance and isolation measures can prevent a few cases from mushrooming into an outbreak.

Antibody, or serology, tests became available in April. They are performed on a blood sample and detect antibodies produced by the body in response to the virus. A positive test indicates that a person was infected at some time in the past. In a paper published recently in the journal Clinical Chemistry, Neil Anderson, MD, an assistant professor of pathology and immunology at Washington University School of Medicine in St. Louis and the assistant medical director of the Clinical Microbiology Laboratory at Barnes-Jewish Hospital, and Christopher Farnsworth, PhD, an instructor of pathology and immunology at the School of Medicine, emphasized the importance of ensuring that antibody tests are used appropriately. Here, they discuss further how such tests should and should not be used.

Why are antibody tests for COVID-19 important?

Farnsworth: Antibody testing is really helpful in monitoring how widely a virus has spread within a community. Such testing could help determine how many people have recovered from the virus, even if they never had symptoms. For many viruses, once about 70% of the population is immune either because they have had a natural infection or, better yet, received a vaccination infected people are less likely to encounter a susceptible person and give them the virus, so transmission goes down and the epidemic ends. Thats called herd immunity. Now, estimates suggest about 1% to 2% of people in the U.S. have been infected with the virus that causes COVID-19, so we are nowhere close to achieving herd immunity.

If my antibody test is positive, does that mean Ive had COVID-19 and wont get it again?

Anderson: A positive test just means your body has produced antibodies in response to a past infection; it doesnt tell us whether those antibodies will protect you from getting re-infected. The only way wed know for sure is if we followed patients who are antibody-positive for months or years to see whether they get re-infected. Those studies are underway by scientists at other institutions, but there is no answer yet.

Can antibody tests decide who can safely go back to work?

Farnsworth: Many people are anxious to get people back to work, but antibody tests may give some people a false sense of security. The problem is that even a highly accurate antibody test like the one we use in our laboratory has false positives and false negatives. When the true rate of infection in a community is very low, you will have more false positives than true positives, no matter how good the test is. In Missouri, we think that fewer than 1% of the population has been infected. In our research, we estimated that if we screened asymptomatic individuals, only one out of seven positive antibody tests in Missouri would be true positives, even with a highly accurate test. So, the other six people may think theyre protected and let their guard down, and then they could get infected and spread the disease. Widespread antibody testing could do more harm than good if people do not understand the limitations of such testing.

How should antibody tests be used?

Anderson: There have not been formal guidelines at the national or local levels regarding how exactly these tests should be used. And, in the absence of such guidelines, many people are anxious to get antibody testing. The way I look at such tests is that theyre a tool. People develop antibodies a week to two weeks into an infection, so antibody tests can support diagnostic tests in identifying current infections. They also can be used for screening or public health surveillance. But, for all these purposes, antibody tests should not be the sole source of information for decision-making. As we learn more about the tests and what theyre capable of, I think well be able to make some evidence-based guidelines to indicate who should be tested and what we should do with the results.

Observations on Safety Procedures to Combat Covid-19 by Former CEO of British Society for Immunology – Euro Weekly News

The following was posted as a comment by Dr Marcus Stephan who now lives on the Costa del Sol but was considered interesting and important enough to publish on this website.

NO-ONE can possibly disagree with the fact that Spain has suffered very badly as a result of Covid-19.

The lockdown measures have been, using any measure, largely successful and the government should be commended as should the vast majority of the population for adhering to the rules.

However, as a former CEO of the British Society for Immunology, I am increasingly becoming frustrated by the over importance being given to what we refer to as fomite transmission. This virus spreads in droplet form from one person to another, there is no doubt about that and so keeping your distance is not only a good idea but the science tells us to do this.

Fomite transmission is what happens when an infected person coughs or sneezes on their hands and they then touch a surface. You then come along and touch the contaminated surface and manage to pick up enough viable virus and then you rub that into your eyes, mouth, or nose. If you do that well enough you may become infected.

There are a lot of ifs to consider, but yes, it is just possible. However, bear all this in mind, first of course viruses are not living things, just tiny specks of stuff and they dont remain viable outside their preferred host for very long.

So, to put it delicately a droplet of human nasal fluid containing virus particles that lands on a hard surface needs to get picked up by you fairly quickly if it is going to do its business and make you sick.

If the droplet dries out, Im afraid the virus particles have had it, likewise if the droplet gets exposed to sunlight, heat, or any well-known cleaning fluid same thing goes. So, you have to be fairly quick off the mark to scrape the virus particles up and make sure they get into you if you want to stand any chance of getting sick.

Im not making light of the fact that if you are in a particular category and you do pick up this virus the consequences can be severe, but I also think it is important we alter our behaviour based on the science.

All this talk of disinfecting sunbeds and disposable menus in restaurants is too much icing on the cake in my view, not just that but for some people this is increasing their anxiety about going out and that can lead to all sorts of other undesirable complications.

If you add a dose of common sense and good manners to the science, we have a near perfect solution until a vaccine arrives. By far and away the most important thing any of us can do is to wash our hands before we fiddle with our faces and that is extremely difficult to do, but if we can do it so much the better.

So even if you did manage to get someone elses infected secretions all over your hand so long as you dont touch your face until you have washed your hands all is OK. The virus doesnt get absorbed through your skin by the way.

The wearing of masks is something you wont get scientists or medics necessarily in agreement when it comes to using them in general. Lets be 100 per cent clear, they do not protect you in any way shape or form of breathing in someone elses sneeze or cough, you need a very special mask for that and these are not generally available.

As a means of cutting down what you might spread if you are infected, so long as you keep it on, they are probably a good idea. Going for a walk in the fresh air or sitting on one of our lovely beaches presents no risk.

The risk only really becomes a reality if you are in a closed in space and you have someone coughing or sneezing all over the place and the air starts to fill with microscopic droplets that dont get blown away and diluted.

Its rather what happened sadly on the cruise ships where people were confined to cabins and the efficient air conditioning system managed to pipe contaminated air from cabin to cabin.

So back to contaminated surfaces, there is a lot of scientific data that shows you need to literally pick up lots, possibly millions, of virus particles for the hand to nose route to be effective, but we believe you need far less if you manage to breath in a someones sneeze and that gets directly to your lungs.

So there really is no need to be over concerned about touching a supermarket trolley and why your payment card might require a touch pad to be sanitised Im afraid I cannot explain except to say that this is an example of science taking a back seat and paranoia muscling in.

One thing Spain hasnt ruled against, and I certainly would, is to stop anyone smoking in public, because you see this virus attacks the respiratory system and exhaled smoke will contain virus particles so if you can smell someone elses smoke then you might be breathing in virus.

The rules being put in place on our beaches for example have very good intentions, but they are a mess. Not only are they a mess but they will add further damage to our much-needed tourism economy, lets not forget that the vast majority of coastal towns in Spain depend on tourism.

Show me a peer-reviewed scientific article that indicates the use of a Lilo in the water presents a real risk of infection. If fomite transmission was a good as we are being led to believe then all the filthy coins and bank notes we pass around between us would be infecting us like wildfire.

Use a tissue when you sneeze and then throw it away, wash your hands before you touch your face. If you think you are infected then do the decent thing and stay at home alone. But dont be afraid to go out and enjoy this lovely part of Spain, all of us just need to take sensible personal responsibility.

Additionally, new insights about the daily burden of living with peanut allergy will be presented to highlight the need for an approved treatment for peanut allergy. To that end, we take great pride in our leadership and dedication to improving the lives of those affected by peanut allergy.

The following abstracts will be available , for on-demand viewing on the EAACI scientific programme website starting at 9:00am CEST / 3:00am EDT on Saturday, June 6, 2020

PALFORZIA Clinical Trial Data

Peanut Allergy Data

Additional Data Involving PALFORZIA

PALFORZIA (previously known as AR101) is an oral immunotherapy indicated for the mitigation of allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanut. PALFORZIA is approved for use in the United States in patients with a confirmed diagnosis of peanut allergy. In Europe, Aimmune has a marketing authorization application for AR101 (PALFORZIA) under review with the European Medicines Agency (EMA).

INDICATION

PALFORZIA is an oral immunotherapy indicated for the mitigation of allergic reactions, including anaphylaxis, that may occur with accidental exposure to peanut. PALFORZIA is approved for use in patients with a confirmed diagnosis of peanut allergy. Initial Dose Escalation may be administered to patients aged 4 through 17 years. Up-Dosing and Maintenance may be continued in patients 4 years of age and older.

PALFORZIA is to be used in conjunction with a peanut-avoidant diet.

Limitations of Use: Not indicated for the emergency treatment of allergic reactions, including anaphylaxis.

IMPORTANT SAFETY INFORMATION

Boxed WARNING:

PALFORZIA can cause anaphylaxis, which may be life threatening and can occur at any time during PALFORZIA therapy.

Prescribe injectable epinephrine, instruct and train patients on its appropriate use, and instruct patients to seek immediate medical care upon its use.

Do not administer PALFORZIA to patients with uncontrolled asthma.

Dose modifications may be necessary following an anaphylactic reaction.

Observe patients during and after administration of the Initial Dose Escalation and the first dose of each Up-Dosing level, for at least 60 minutes.

PALFORZIA is available only through a restricted program called the PALFORZIA REMS.

CONTRAINDICATIONS

PALFORZIA is contraindicated in patients with uncontrolled asthma, or with a history of eosinophilic esophagitis and other eosinophilic gastrointestinal disease

WARNINGS AND PRECAUTIONS

Anaphylaxis

PALFORZIA can cause anaphylaxis, which may be life threatening. PALFORZIA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the PALFORZIA REMS because of the risk of anaphylaxis. Only prescribers, healthcare settings, pharmacies, and patients certified and enrolled in the REMS Program can prescribe, receive, dispense or administer PALFORZIA.

Anaphylaxis has been reported during all phases of PALFORZIA dosing, including Maintenance and in subjects who have undergone recommended Up-Dosing and dose modification procedures.

Do not initiate PALFORZIA treatment in a patient who has had severe or life-threatening anaphylaxis within the previous 60 days. PALFORZIA may not be suitable for patients with certain medical conditions that may reduce the ability to survive anaphylaxis, including but not limited to markedly compromised lung function, severe mast cell disorder, or cardiovascular disease. In addition, PALFORZIA may not be suitable for patients taking medications that can inhibit or potentiate the effects of epinephrine.

All Initial Dose Escalation doses and the first dose of each Up-Dosing level must be administered in a certified health care setting.

Patients may be more likely to experience allergic reactions following PALFORZIA administration in the presence of cofactors such as exercise, hot water exposure, intercurrent illness (e.g., viral infection), or fasting. Other potential cofactors may include menstruation, sleep deprivation, nonsteroidal anti-inflammatory drug use, or uncontrolled asthma. Patients should be proactively counseled about the potential for the increased risk of anaphylaxis in the presence of these cofactors. If possible, adjust the time of dosing to avoid these cofactors. If it is not possible to avoid these cofactors, consider withholding PALFORZIA temporarily.

Asthma

Uncontrolled asthma is a risk factor for a serious outcome, including death, in anaphylaxis. Ensure patients with asthma have their asthma under control prior to initiation of PALFORZIA.

PALFORZIA should be temporarily withheld if the patient is experiencing an acute asthma exacerbation. Following resolution of the exacerbation, resumption of PALFORZIA should be undertaken cautiously. Re-evaluate patients who have recurrent asthma exacerbations and consider discontinuation of PALFORZIA.

Eosinophilic Gastrointestinal Disease

Discontinue PALFORZIA and consider a diagnosis of eosinophilic esophagitis in patients who experience severe or persistent gastrointestinal symptoms, including dysphagia, vomiting, nausea, gastroesophageal reflux, chest pain, or abdominal pain.

Gastrointestinal Adverse Reactions

Gastrointestinal adverse reactions were commonly reported in PALFORZIA-treated subjects, and dose modification should be considered for patients who report these reactions. For severe or persistent gastrointestinal symptoms consider a diagnosis of eosinophilic esophagitis.

ADVERSE REACTIONS

The most common adverse events reported in subjects treated with PALFORZIA (incidence 5% and 5% than placebo) are abdominal pain, vomiting, nausea, oral pruritus, oral paresthesia, throat irritation, cough, rhinorrhea, sneezing, throat tightness, wheezing, dyspnea, pruritus, urticaria, anaphylactic reaction, and ear pruritus.

Lilly starts COVID-19 antibody trial, expanding on earlier efforts – BioWorld Online

Eli Lilly and Co. said June 1 the first patients have been dosed in a phase I test of LY-CoV555, a potential antibody treatment for COVID-19, with results expected by June 30. Should it prove safe, the candidate could quickly move into a phase II trial to assess its efficacy, Ajay Nirula, vice president of immunology at Lilly, told BioWorld. The news follows Lilly's May 4 announcement of efforts to co-develop antibodies for the prevention and treatment of the infection with Shanghai Junshi Biosciences Ltd. and testing of its already-marketed small-molecule JAK inhibitor, Olumiant (baricitinib), as part of the NIH-led adaptive COVID-19 treatment trial.

The new candidate, a neutralizing IgG1 monoclonal antibody directed against the spike protein of SARS-CoV-2, is the first to emerge from Lilly's collaboration with Abcellera Biologics Inc., a deal that itself was just signed in early March. Under the terms of the agreement, Abcellera and Lilly committed to equally share initial development costs toward a product, after which Lilly will be responsible for all further development, manufacturing and distribution work and costs.

Lilly's work joins significant efforts underway at Regeneron Pharmaceuticals Inc., Roche Holding AG, Vir Biotechnology Inc., Celltrion Inc. and academic institutions such as the University of Toronto, all of which are pursuing the development of antibody therapeutics for the virus. Though the Regeneron and Roche programs have already entered the clinic, clinical testing of LY-CoV555 appears to be the first clinical effort to evaluate an antibody specifically designed to block SARS-CoV-2's attachment and entry into human cells.

The candidate was generated in just three months after Abcellera and the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases identified it from a blood sample taken from one of the first U.S. patients who recovered from COVID-19.

Vancouver, British Columbia-based Abcellera's high-throughput microfluidics platform, adapted through the Defense Advanced Research Projects Agency's Pandemic Prevention Program for rapid response to pandemics, employs machine vision and artificial intelligence to identify immune cells and the exact sequences of antibodies they create. In this case, Lilly analyzed antibodies from the recovered patient, characterizing close to 500 of them to understand which ones were most potent at blocking SARS-CoV-2. In vitro and other testing helped narrow the scope even further before the company moved to generate a version of the most promising one for testing in the new phase I study.

The placebo-controlled trial, called J2W-MC-PYAA, is likely to enroll about 30 hospitalized COVID-19 patients. The key goals are to understand the safety and tolerability of the antibody, the pharmacokinetics that can guide dosing. But investigators, who started dosing patients Friday at the NYU Grossman School of Medicine and Cedars-Sinai in Los Angeles, will also help Lilly look at exploratory efficacy endpoints, such as measures of patient viral loads.

While Lilly is initially focused on testing LY-CoV555 in hospitalized patients, "ultimately, we want to branch out the program into different patient populations," Nirula said. The team is also interested in moving into other trials where they would study patients before they're hospitalized to see if administration of a therapeutic antibody earlier in the course of the disease could prevent progression to hospitalization or even play a prophylactic role. Such studies could be underway "in the relatively near future," he said.

Further potential studies could explore whether an antibody might be effective in combination with other medicines, such as Gilead Sciences Inc.'s remdesivir.

Later this month, Lilly's team will review the results of the phase I study of LY-CoV555 before potentially starting broader efficacy trials. But, in an illustration of the substantial urgency Lilly and other drugmakers see in the market, the Indianapolis company is also starting large-scale manufacturing of the potential therapy, it said.

"If LY-CoV555 becomes part of the near-term solution for COVID-19, we want to be ready to deliver it to patients as quickly as possible, with the goal of having several hundred thousand doses available by the end of the year," said Daniel Skovronsky, Lilly's chief scientific officer and president of Lilly Research Laboratories.

Meanwhile, together with Junshi Biosciences, Lilly is expected to file an IND and initiate clinical trials in the U.S. and China in the second quarter. That program, recently documented in an article in Nature, is also employing antibodies isolated from a recovered COVID-19 patient.

Lilly shares (NYSE:LLY) moved little on June 1, losing 50 cents to close at $152.45.

Coronavirus weekly: recovery efforts happening in fits and starts – The Conversation UK

The world is moving slowly and carefully to reopen businesses, get people back to work and jump-start moribund economies amid the COVID-19 pandemic.

Some initial attempts have been characterized by stops and starts as new clusters of the disease emerge. In Toronto, Canada, young people recently gathered en masse in a city park, fuelling outrage and sparking fears of more sudden and unexpected spikes in COVID-19 cases.

In this weeks roundup of coronavirus stories from scholars across the globe, we explore how our post-pandemic lives will be different, the latest medical developments and how to keep spirits up as lockdowns endure.

This is our weekly roundup of expert info about the coronavirus.The Conversation, a not-for-profit group, works with a wide range of academics across its global network. Together we produce evidence-based analysis and insights. The articles are free to read there is no paywall and to republish. Keep up to date with the latest research by reading our free newsletter.

As businesses reopen and employees begin to return to work, nothing is truly going back to normal. In fact, the post-pandemic world will require a vastly new normal until theres a COVID-19 vaccine. And that means rethinking and reimagining how weve always done things.

Getting out and about. Were all experiencing a bit of cabin fever, and some people are having trouble respecting social distancing rules when they are venturing out into the world. William Petri, a professor of medicine at the University of Virginia who specializes in immunology, outlines the seven factors hell assess to determine when its safe enough to spend time away from home. He writes: I am going to wear a mask to help prevent my giving the infection to others, avoid touching surfaces such as handrails, try not to touch my eyes or nose or mouth with my hands and wash my hands frequently.

Public transit. Hopping on a bus or subway during rush hour to get to work is a longtime urban ritual. But COVID-19 has likely changed how we do it so were no longer squeezed in like sardines. But Hussein Dia of Australias Swinburne University of Technology says that public transit is here to stay; not everyone can walk or ride bikes to their destination, and so public transit will remain at the heart of urban mobility. Dia advocates rethinking public transit design to enable physical distancing, even though it reduces capacity.

Air travel. The same goes for air travel, write Kacey Ernst and Paloma Beamer, epidemiologist and exposure scientist, respectively. They have some tips for air travel and masks are, once again, a central recommendation, along with hand sanitizer.

Doing business differently. For businesses opening their doors to customers once again, its a brave new world one that will require them to take into account the fears and anxieties their employees and customers are feeling right now. According to M. Tina Dacin and Laura Reese, organizational behaviour experts at Queens University in Canada, businesses will have to win the hearts and minds of their customers and employees like never before.

African trade. African countries may benefit from this new normal. Faizel Ismail, director of the Nelson Mandela School of Public Governance at the University of Cape Town, writes that pandemic could be an opportunity to advance free trade via the African Continental Free Trade Area in a more developmental, inclusive and mutually beneficial way for African countries.

Tourism. Could a four-day work week help the struggling tourism industry post-pandemic? Jarrod Haar of Auckland University of Technology makes the case after New Zealand Prime Minister Jacinda Ardern floated the idea of shortening the traditional work week following COVID-19. Healthier, happier and more productive workers helping other businesses stay viable? That sounds like a win-win for all, he writes.

What about the animals? Kendra Coulter, an animal ethics expert at Canadas Brock University, makes a passionate case to promote the well-being of animals post-pandemic, arguing that COVID-19 has illuminated how terribly we treat them. She points to a coronavirus outbreak among low-income workers at a Canadian meat-packing plant, writing that contemporary slaughterhouses have proven to be dangerous for workers in addition to being fatal horror shows for animals.

And speaking of animals, llamas yes, llamas are among the bright spots in efforts to find a cure for COVID-19.

Whats the latest with tests? Shayan Sharif and Byram W. Bridle of the University of Guelph in Canada, meanwhile, explain the pitfalls and promises when it comes to antibody tests. According to the immunology experts: Can we conceivably use antibody testing as a measure of immunity? The answer is maybe!

A US state is getting it right. Since South Carolinas first COVID-19 case surfaced, trained case investigators have traced the contacts of every person who tested positive. Jenny Meredith, a pathology professor at the University of South Carolina School of Medicine, outlines what else the state got right, noting that contact tracing is critical to reopening the economy without triggering a spike in coronavirus cases and overwhelming health-care systems.

Were all fed up, anxious and occasionally depressed by the COVID-19 shutdowns as we take tentative, cautious steps towards the new normal. Thankfully our global network has offered up some advice on how to tackle the impact on our mental health and well-being.

Therapy. Nicholas Joyce, a psychologist at the University of South Florida, points out that online therapy is having its moment in the sun and helping those struggling with mental health issues during the pandemic. He argues that COVID-19 has made clear that telehealth is the way of the future.

Robust mental health. Simon Rosenbaum and Jill Newby of Australias UNSW outline the characteristics of strong mental health, and offer up some tips to keep the COVID-19 blues at bay.

Social enterprise. Anyone whos ever been lucky enough to spend time in the Canadian province of Newfoundland and Labrador knows the place itself can serve as a balm to frayed nerves. Natalie Slawinski of Memorial University and Wendy K. Smith of the University of Delaware explain how a social enterprise saved the remote fishing outpost of Fogo Island following the collapse of the cod industry and they can help local communities around the world recover from the COVID-19 pandemic.

"Psoriatic arthritis is a complex heterogeneous disease with manifestations across multiple domains, including joints and skin, causing daily pain, fatigue and stiffness," said Michael Severino, M.D., vice chairman and president, AbbVie. "We look forward to working with regulatory authorities and hope to bring RINVOQ to people living with this debilitating disease as quickly as possible."

The applications are supported by data from two Phase 3 studies across a broad range of more than 2,000 patients with active psoriatic arthritis.1,2 In both studies, RINVOQ met the primary endpoint of ACR20 response at week 12 versus placebo.1,2 RINVOQ 15 mg also achieved non-inferiority versus adalimumab in terms of ACR20 response at week 12.1 Patients receiving RINVOQ also experienced greater improvements in physical function (HAQ-DI) and skin symptoms (PASI 75), and a greater proportion achieved minimal disease activity.*,1,2 Overall, the safety profile of RINVOQ in psoriatic arthritis was consistent with previously reported results across the Phase 3 rheumatoid arthritis clinical trial program, with no new significant safety risks detected.1-3

*Physical function was measured by the Health Assessment Questionnaire Disability Index (HAQ-DI). Skin symptoms were measured by a 75 percent improvement in the Psoriasis Area Severity Index (PASI 75). Minimal disease activity is defined as the fulfillment of five of seven outcome measures: Tender joint count 1; swollen joint count 1; PASI 1 or body surface area-psoriasis 3 percent; Patient's Assessment of Pain Numerical Rating Scale (NRS) 1.5; Patient Global Assessment-Disease Activity NRS 2.0; HAQ-DI score 0.5; and Leeds Enthesitis Index 1.

About RINVOQ (upadacitinib)

Discovered and developed by AbbVie scientists, RINVOQ is a selective and reversible JAK inhibitor that is being studied in several immune-mediated inflammatory diseases.1,2,4-10 In August 2019, RINVOQ received U.S. FDA approval for adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to methotrexate. In December 2019, RINVOQ was approved by the European Commission for the treatment of adult patients with moderate to severe active rheumatoid arthritis who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs. The approved dose for RINVOQ in rheumatoid arthritis is 15 mg. Phase 3 trials of RINVOQ in psoriatic arthritis, rheumatoid arthritis, axial spondyloarthritis, Crohn's disease, atopic dermatitis, ulcerative colitis and giant cell arteritis are ongoing.1,2,4-10 Use of RINVOQ in psoriatic arthritis is not approved and its safety and efficacy have not been established by regulatory authorities.

A new Benchmark in shrimp production – The Fish Site

As Benchmarks shrimp facility in Florida begins to gear up towards commercial production, Oscar Hennig, operations director of Benchmark Genetics shrimp-breeding programme who has been in the shrimp sector for nearly 30 years explains to The Fish Site what he hopes to achieve.

Benchmark Genetics

Ive been involved in the sector since 1991, starting off on farms in Australia. After finishing my masters in aquaculture in Florianpolis [in southern Brazil] I received a scholarship from the government of Japan for a two-year research project with shrimp immunology at the Shimonoseki National Fisheries University. From there I returned to Brazil for two years running a diagnostics lab for shrimp at the LABOMAR research institute. In the meantime, to make ends meet, I leased a growout farm. P. vannamei [whiteleg shrimp] farming was just starting in north-east Brazil and there was the need for expertise to help the transition from P. subtilis [southern brown shrimp].

At the end of 1999 I moved permanently to Hawaii, to manage a satellite facility of the Oceanic Institute, in Kona. I have been in Kona ever since, working as breeding-programme manager for different companies, with P. monodon [giant tiger prawn], P. stylirostris [blue shrimp] and mainly P. vannamei.

At the end of 2016 I was hired as a director for Benchmark Genetics, after Benchmark had bought CENIACUA, a P. vannamei breeding programme in Colombia. My role has been to bring this to the international arena.

Oscar Hennig

I was impressed by the CENIACUA facility, and the crew running it, in Cartagena we had as much space as we wanted and as many people as we needed, as the jobs were in the local community.

However, Cartagena doesnt have great logistics and we realised that we need a base in the US to improve our ability to export our stocks.

[The Central Florida town of] Fellsmere was suitable for a number of reasons, not least for being close to three international airports. It is also 30km from the coast, which helps with our biosecurity and also to protect us from the hurricanes that can devastate the Florida coast.

Back in 2017, when we selected the site, my only concern was that we were sourcing water from a well this can impact the fertilisation ratio but weve managed to produce steady numbers of nauplii.

Benchmark Genetics

The water comes from 750m deep, and the well brings a sterile (zero dissolved oxygen), ~32 ppt saline water that is second to none. Due to the inland location, discharging water is a challenge, so all our systems work on recirculation or on biofloc.

All activities are conducted indoors from maturation, to algae, to grow-out, to packing so the biosecurity is excellent.

Im proud of how its turned out and Im really happy with the team weve created. There are currently 15 people involved and theres plenty of space to expand. At the moment were operating at about one fifth of our capacity, as were conducting presale trials, in order to fine tune the lines of shrimp that are needed in our main markets China, Vietnam, Indonesia and Thailand and these are now being tested in a commercial environment.

Most shrimp producers only offer one product but there are so many production systems used by the global shrimp industry and we saw that one size does not fit all. As a result, we decided to cater for a range of options and have launched three lines commercially.

The first, which weve been developing since 2008, is resistant to whitespot, EMS and other diseases. Called BMK Protect this is mainly for customers in northern China, and other areas facing disease challenges. It shows its true potential in harsh/disease conditions.

The second line was bred specifically to improve performance in sites with low salinity: shrimp farming is becoming increasingly popular in water thats less than 5 ppt. It now accounts for roughly 60 percent of Indian shrimp production, 50 percent in China, 15 percent in Vietnam and 15 to 20 percent in Thailand.

The third line, called BMK Yield, balances growth rates with survival to ensure steady production. It produces a consistent yield and a high rate of survival, making it ideal for farms that are working with processing plants, as it allows the farmer to provide a steady supply of raw material.

Benchmark Genetics

At this moment we are using some of that capacity to produce PLs for farmers, in the US and abroad. The PPL will go to our partners multiplication centres worldwide. China has been the main market during this presale year, and BMK Protect has been the number one line. The other two are doing well in the presale, but their evaluation still ongoing.

Breeding without ablation is not a big deal for us; it takes more planning and a few adjustments but nothing major. It is not done at the commercial hatcheries [as opposed to broodstock production facilities] due to a ~30 percent reduction in nauplii production. This reduction off nauplii output is mainly due to the lower frequency of female spawning, not due to lower levels of nauplii per spawn.

We believe that PL produced by non-ablated females are stronger. We ran some trials to support this belief and found that the eggs were bigger in non-ablated females, which makes sense as they have more time to go through the maturation process. We have other trials in mind that we will pursue once we get back to a normal routine.

Consolidation of the industry at different levels and partnership with local companies. I see the industry moving in two extreme directions: high-density, enclosed, biosecure farming systems and extensive open ponds, with not much left in the middle.

There was a small decline in sales during February and it has been hard to get cargo space and to predict when flights would go logistics have been crazy and transport prices also increased. However, I am optimistic that, once Covid-19 is a thing of the past, people will be wanting to celebrate life and demand for shrimp will increase beyond levels prior to this pandemic. As a result, our plan to expand is still in place.

Board elects two members, honors three life trustees – University of Rochester

May 26, 2020

At a virtual May meeting, the University of Rochester Board of Trustees elected two new board members and recognized three individuals who become life trustees.

I am thrilled to welcome Betsy Ward and Martin Sanders to the board, said Board Chair Rich Handler 83. Its during an unprecedented time in the Universitys history that they are joining us, and their expertise and commitment to the University are needed now more than ever. I also want to express my gratitude to our new life trustees for their distinguished service over many years. We look forward to their continued engagement with the University.

University President Sarah Mangelsdorf said, I wish to welcome our newly elected members to the board and thank them in advance for their commitment. Im also very grateful to our newest life trustees, all of whom have made invaluable contributions to the University and provided wise counsel and support to me in my first year as president.

With current circumstances resulting from the COVID-19 pandemic, both new and life trustees will be recognized in person at a later date.

Martin Sanders is cofounder and CEO of Io Therapeutics, Inc., a privately held company based in Santa Ana, California, that develops treatments for Parkinsons disease, Alzheimers disease, multiple sclerosis, and various cancers. He is also the executive chairman of the companys board of directors.

Sanders, a medical doctor, has had a long career in clinical medicine, basic laboratory research in immunology, drug discovery research, pharmaceutical product development, patient care, venture capital investment, and serial company formation in the life sciences. He holds many patents, including one that was granted in March 2020 for treating nervous system disorders. Dedicated to bringing new treatments to people suffering from Parkinsons disease, cancer, migraines, and blindness, he has served as an advisor to more than 50 biopharmaceutical companies in the areas of preclinical and clinical product development since 1992.

Sanders is a passionate supporter of the arts and believes that art and music play a role in good health. In 2018, he and his wife, Corazon, established the Martin E. and Corazon D. Sanders Professorship in Voice at the Eastman School of Music in appreciation of their daughter, Lauras, voice teacher. Laura earned her bachelors degree in 2016 and a masters degree in 2018 in voice and opera from Eastman. Through the Sanderss generosity, Eastman celebrated the first installation of a performance faculty member into an endowed position. In addition, Martin Sanders is a member of the Eastman School of Music National Council and the University of Rochester Volunteer Task Force.

He received his medical degree from the University of Chicago; served as an intern and resident in internal medicine at Washington University Medical Center in St. Louis; and completed three postdoctoral fellowships in allergy/clinical immunology at the National Institute of Allergy and Infectious Diseases, in rheumatology at Johns Hopkins Medical School, and in cancer immunology at the immunology branch of the National Cancer Institute. He is board certified in internal medicine and in subspecialties allergy/clinical immunology and rheumatology.

Elizabeth (Betsy) Ward 86 is the chief financial officer at MassMutual, leading the finance department at the nearly 170-year-old life insurance company into a new era, with a focus on connecting finance to broader strategic planning. Before becoming CFO in 2016, she held several prominent positions at the Springfield, Massachusettsbased company, including chief enterprise risk officer and managing director at a couple of their subsidiary asset management firms.

Ward serves on the US Department of the Treasurys Federal Advisory Committee on Insurance and has been a member of the American Academy of Actuaries and the Fellow Society of Actuaries since the early 1990s. She has been a key contributor to global risk management through her work leading various industry groups. She has also served on federal committees on supervisory requirements and research, focusing on the effective groupwide supervision of insurance groups and seeking to narrow the gaps among global regulatory regimes.

Ward earned a bachelors degree in economics and Spanish from the University, while also studying flute through lessons at the Eastman School of Music. Music continues to play an important role in her life. She serves on the board of directors of the Community Music School of Springfield and continues to perform on flute in local classical ensembles, and as an alto singer with chamber choirs and chorales in Connecticut and Massachusetts.

In November 2019, Ward was the keynote speaker at the Universitys Simon Womens Conference. In 2012, she was named by Diversity Journal as a Woman Worth Watching in Financial Services, and in 2014, she was cited by Insurance Risk magazine as CRO of the Year.

At the May meeting, the board approved the transition of three individuals to life trustee status. Together the individuals have provided years of distinguished service to the board and their philanthropy has supported the creation of new facilities, scholarships, professorships, and other initiatives throughout the University.

Kathleen Murray 77 has been a board member since 2010, serving at different times on the Academic Affairs, Audit and Risk Assessment, Executive, Facilities, Human Resources, and Nominations and Board Practices committees. In her role as trustee, she has lent her business expertise to assist leadership in complex strategic, financial, and managerial issues, as well as supported key University goals through service on the Diversity Advisory Council, the NY Metro Women Steering Committee (for which she is chair emeritus), River Campus Libraries National Council, and Meliora Campaign Cabinet Chair.

In Arts, Sciences & Engineering, she established the Kathleen McMorran Murray 74 Endowed Scholarship Fund and Rochester Annual Fund. She has also exemplified generosity to other units of the University, particularly to the College Annual Fund, Diversity Program Fund, and the River Campus Libraries Annual Fund.

Francis Price 74, 75S (MBA) has provided business, financial and strategic advice to the University since he joined the Board in 1995. He has served on the Academic Affairs, Executive, Executive Alternate, Financial Planning (now Strategic and Financial Planning), Health Affairs, Nominations and Board Practices, and Student Affairs (now Student Life) committees during his tenure.

Price has additionally served on the Memorial Art Gallery Board of Managers, Diversity Initiative Campaign Committee; Hajim School of Engineering Visiting Committee; Los Angeles Regional Cabinet; and the Multicultural Alumni Advisory Council Executive Committee. In 2016, he volunteered his time to serve as the inaugural chair of the Public Safety Review Board.

He has generously supported the David T. Kearns Center, African-American Institute Gift Account, and the College Annual Fund.

E. Philip Saunders has provided distinguished service to the University as a member of the Board of Trustees since 2015. He has encouraged valuable discussions and principled engagement in a wide range of issues affecting the University. He has served with distinction on the Health Boards Affairs Committee, and served as Rochester Philanthropy Council chair; Medical Center Campaign Cabinet cochair; Medical Center Meliora Campaign vice-chair; and George Eastman Circle Rochester Leadership Council chair.

Saunders has provided extraordinary philanthropic support to the University. In 2011, he contributed $10 million to the University of Rochester Medical Center to support neuromuscular disease and translational research. The Saunders Research Building, home to the Clinical and Translational Science Institute, clinical research programs, and academic departments, was named in his honor. His gift also supports the Saunders Family Distinguished Professorship in Neuromuscular Research and the E. Philip and Carole Saunders Professorship in Neuromuscular Research. He served as a cochair of the Medical Centers campaign in support of The Meliora Challenge and honorary chair of the George Eastman Circle Rochester Leadership Council. He greatly influenced and encouraged philanthropy with the creation of the highly successful George Eastman Circle Plus One outreach concept, inspiring other units of the University to adopt the concept to increase engagement.
