The National Institutes of Health has awarded the University of Georgia a contract to establish the Center for Influenza Disease and Emergence Research (CIDER). The contract will provide $1 million in first-year funding and is expected to be supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH, for seven years and up to approximately $92 million. Scientists in the multi-institutional center will work to increase understanding of influenza virus emergence and infection in humans and animals while also making preparations to combat future outbreaks or pandemics.

The contract is the university’s second major NIH award for influenza research in less than two years. These two awards represent a potential NIH investment of more than $220 million in UGA’s flu research, which unites scientists from a wide range of disciplines across the university.

“As the COVID-19 pandemic has demonstrated, an effective response to a fast-spreading infectious disease requires coordinated effort among multiple disciplines,” said UGA President Jere W. Morehead. “This latest award demonstrates the NIH’s continuing confidence in the research expertise and capacity of the University of Georgia’s top scientists.”

In addition to faculty from multiple units across UGA, CIDER will include external partners such as Boston Children’s Hospital, St. Jude Children’s Hospital, the University of Rochester and the University of Melbourne. It will be directed by S. Mark Tompkins, professor of infectious diseases in UGA’s College of Veterinary Medicine, and its deputy director will be Pejman Rohani, Regents’ Professor and UGA Athletic Association Professor in Ecology and Infectious Diseases in the Odum School of Ecology and College of Veterinary Medicine.

CIDER becomes part of a national network of Centers of Excellence in Influenza Research and Response established by the National Institute of Allergy and Infectious Diseases.

The dynamics of flu

Influenza viruses are categorized by four major types: A, B, C and D. Historically, most flu research has focused on flu A because its subtypes–such as H1N1 and H3N2–have caused most seasonal influenza disease and have been responsible for pandemic outbreaks in the past. Further, because flu A infects species other than humans, including birds and pigs, there is the ever-present danger of the spillover of a novel virus to humans.

In addition to flu A, research in CIDER will study flu B, which is almost exclusively found in humans. While flu B has not caused a pandemic to date, its lineages circulate seasonally just like flu A and regularly cause local epidemics, burdening public health. (Flu C and D essentially are found only in other species.)

“Influenza B is a significant human pathogen that competes every year with flu A, but surprisingly we know relatively little about it compared to flu A,” Tompkins said. “Through CIDER’s basic research, we want to better understand the transmission of these viruses, the resulting disease severity, and the host response to infection and disease. This work will enable development of better vaccines and better understanding for public health responses–particularly for flu but potentially for other pathogens.”

CIDER’s collaborative structure, involving national and international partners, will enable it to conduct not only basic research but also clinical work with both adults and children, including longitudinal studies of vaccine response among high-risk populations and those hospitalized with severe disease.

“The establishment of the Center for Influenza Disease and Emergence Research will bring leading researchers from a range of fields at the University of Georgia and other institutions together to address the urgent challenge that influenza poses to global health,” said S. Jack Hu, UGA’s senior vice president for academic affairs and provost.

A major thrust will be studying the evolution of flu virus as it replicates and moves among hosts. One interesting fact about flu B, Rohani said, is that its two major lineages appear to be evolving in different directions: one toward greater transmissibility among different hosts and the other toward a greater ability to infect the same host more than once. These two paths constitute different “life history strategies,” he said.

“That’s a fascinating and exciting evolutionary question,” Rohani said. “Why would one turn right, so to speak, and one turn left when they get to this fork in the road? Or, indeed, why is there a fork in the road? One of the long-standing puzzles in the biology of infectious disease is understanding the evolutionary strategies of different viruses.”

Building on interdisciplinary strength

The contract is UGA’s second major NIH award for flu research in less than two years. In September 2019, UGA received a contract worth up to $130 million to establish one of several Collaborative Influenza Vaccine Innovation Centers across the country working to develop a “universal” flu vaccine that would be effective against any strain of the influenza virus that can infect humans.

One of the many reasons UGA was selected to create CIDER so quickly on the heels of the 2019 CIVIC award is the collection of strengths the university brings to the challenge of flu and other infectious diseases. Tompkins and many of his fellow UGA virologists and immunologists are in the College of Veterinary Medicine, which is an asset in studying zoonotic diseases that spread between animals and humans.

The College of Veterinary Medicine researchers are complemented by computational biologists and bioinformaticists like Rohani, by epidemiologists in the College of Public Health, and by public health communication experts in the Grady College of Journalism and Mass Communication, in addition to scientists in other related fields around the university.

UGA is also home to a state-of-the-art biocontainment facility necessary to study live virus and the Complex Carbohydrate Research Center, a world leader in studying the complex sugars used by many viruses–including both flu and SARS-CoV-2–to bind to their hosts.

“We have a lot of different pieces that can create these synergies to make us a national leader in this area,” Tompkins said. “Building this capacity is not something that happens overnight–this has been an area of focus at different levels over many years.”

This wide-ranging expertise will better enable UGA to provide training opportunities for the next generation of scientists, another facet of CIDER’s activities. CIDER will award pilot grants to junior faculty to develop research projects around flu and stage regular workshops that pull together multiple specialties and demonstrate firsthand the value of interdisciplinary collaboration.

“CIDER is yet another positive reflection of the deliberate, strategic investments UGA has made in interdisciplinary infectious disease research over the past two decades,” said David Lee, vice president for research. “Thanks to these investments, UGA is now in a position to lead a team of outstanding institutions to mitigate the impacts of this ongoing public health challenge.”

Spread & Containment

TJ Maxx and Marshalls follow Costco and Target on upcoming closures

Many of these stores have information customers need to know.

Published

on

U.S. consumers have come to increasingly rely on the near ubiquity of convenience stores and big-box retailers. 

Many of us depend on these stores being open practically all day, every day, even during some of the biggest holidays. After all, Black Friday beckons retail stores to open just hours after a Thanksgiving Day dinner in hopes of attracting huge crowds of shoppers in search of early holiday sales. 

Related: Walmart announces more store closures for 2024

And it's largely true that before the covid pandemic most of our favorite stores were open all the time. Practically nothing — from inclement weather to bad news to holidays — could shut down a major operation like Walmart  (WMT)  or Target  (TGT)

Then the pandemic hit, and it turned everything we thought we knew about retail operations upside down. 

Everything from grocery stores to shopping malls shut down in an effort to contain potential spread. And when they finally reopened to the public, different stores took different precautionary measures. Some monitored how many shoppers were inside at once, while others implemented foot-traffic rules dictating where one could enter and exit an aisle. And almost every one of them mandated wearing masks at one point or another. 

Though these safety measures seem like a distant memory, one relic from the early 2020s remains firmly a part of our new American retail life.

Store closures announced for spring 2024

Many retailers have learned to adapt after a volatile start to this third decade, and in many ways this requires serving customers better and treating employees better to retain a workforce. 

In some cases, the changes also reflect a change in shopping behavior, as more customers order online and leave more breathing room for brick-and-mortar operations. This also means more time for employees. 

Thanks to this, big retailers have recently changed how they operate, especially during holiday hours, with Walmart recently saying it would close during Thanksgiving to give employees more time to spend with loved ones.

"I am delighted to share that once again, we'll be closing our doors for Thanksgiving this year," Walmart U.S. CEO John Furner told associates in a video posted to Twitter in November. "Thanksgiving is such a special day during a very busy season. We want you to spend that day at home with family and loved ones." 

Other retailers have now followed suit, with Costco  (COST) , Aldi, and Target all saying they would close their doors for 24 hours on Easter Sunday, March 31. 

Now, the stores that operate under TJX Cos.  (TJX)  will also shut down during the holiday, including HomeGoods, TJ Maxx and Marshalls

Though it closed on Thanksgiving, Walmart says it will remain open for shoppers on Easter. 

Here's a list of stores that are closing for Easter 2024: 

  • Target
  • Costco
  • Aldi
  • TJ Maxx
  • Marshalls
  • HomeGoods
  • Publix
  • Macy's
  • Best Buy
  • Apple
  • ACE Hardware

Others are expected to remain open, including:

  • Walmart
  • Ikea
  • Petco
  • Home Depot

Most of the stores closing on Sunday will reopen for regular business hours on Monday.

Gates-backed PhIII study tuberculosis vaccine study gets underway

Published

A large study of an experimental vaccine for the world’s biggest infectious disease has finally kicked off in South Africa.

The Bill & Melinda Gates Medical Research Institute (MRI) will test a tuberculosis vaccine’s ability to prevent latent infections from causing potentially deadly lung disease. Last summer the nonprofit said it would foot $400 million of the estimated $550 million cost of running the 20,000-person Phase III trial.

It’s a pivotal moment for a vaccine whose origins date back 25 years when scientists identified two proteins that triggered strong immunity to the bacterium that causes tuberculosis. A fusion of those proteins, paired with the tree bark-derived adjuvant that helps power GSK’s shingles shot, comprise the so-called M72 vaccine.

Thomas Scriba

After decades of failures in the field, the vaccine impressed scientists in 2018 when GSK found that it was 54% efficacious at preventing lung disease in a 3,600-person Phase IIb study.

But the Big Pharma decided that a full-blown trial was too expensive to conduct on its own. Gates MRI stepped in to license the vaccine in early 2020, right before the Covid pandemic shifted global vaccine priorities towards the coronavirus, further stalling the tuberculosis shot.

“There’s been frustration that it’s taken so long to get this trial up and running,” Thomas Scriba, deputy director of immunology for the South African Tuberculosis Vaccine Initiative, told Endpoints News last summer.

At last, the vaccine is getting a chance to prove itself in a bigger study. If successful, it could lead to the first new shot for tuberculosis in over a century.

Emilio Emini, CEO of the Gates MRI, told Endpoints that the initial results may come in roughly four to six years. “Hopefully this will galvanize a refocus on TB,” he said. “It’s been ignored for many, many years. We can’t ignore it anymore.”

A substantial impact

Even though an existing vaccine helps protect babies and children against severe tuberculosis, the bacterium responsible for the disease still causes roughly 10 million new cases and 500,000 deaths each year.

Emilio Emini

By vaccinating adolescents and adults who test positive for infections but don’t have symptoms of lung disease, the Gates MRI hopes the shot will help prevent mild infections from becoming severe ones, curtail transmission of the bug, which is predominantly driven by people with lung disease, and reduce deaths.

“The impact would be substantial,” Emini said. But he cautioned that the biology behind mild and severe diseases is still mysterious. “The reality is that no one really knows what keeps it under control.”

The study, which will take place at 60 sites across seven countries, will include some people who are not infected with tuberculosis to ensure that the vaccine is safe in that broader population.

“Having to pre-test everybody is not going to make the vaccine easy to deliver,” Emini said. If the vaccine is ultimately approved, it will likely be used in targeted communities with high tuberculosis, rather than across a whole country, he added. “In practice, you would immunize everybody in those populations.”

Emini described the Gates MRI’s rights to the vaccine as “close to a worldwide license.” GSK retained rights to commercialize the vaccine in certain countries but declined to specify which ones.

A spokesperson for GSK said that the company “has around 30 assets under development specifically for global health … none of which are expected to generate significant return on investment.”

“It is not sustainable or practical in the longer term for GSK to deliver all of these alone. So we continue to work on M72, but in partnership with others,” the spokesperson added.

If the shot works, Emini said that the Gates MRI will sublicense it to a manufacturer that will be responsible for making and marketing the vaccine. The details are still being worked out, he noted.

COVID-19 illness may include symptoms such as a sore throat, fever, cough and fatigue. In January, the United States Centers for Disease Control and Prevention (CDC) issued its most recent guidelines for the use of over the counter (OTC) drugs for COVID-19. Specifically, its guidelines state that most people with COVID-19 have mild illness and can recover at home while treating symptoms with OTC medicines such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil).

COVID-19 illness may include symptoms such as a sore throat, fever, cough and fatigue. In January, the United States Centers for Disease Control and Prevention (CDC) issued its most recent guidelines for the use of over the counter (OTC) drugs for COVID-19. Specifically, its guidelines state that most people with COVID-19 have mild illness and can recover at home while treating symptoms with OTC medicines such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil). 

Researchers from Florida Atlantic University’s Schmidt College of Medicine and academic colleagues say it’s more complicated. They suggest that selecting an OTC medication to alleviate mild symptoms of COVID-19 should be based on the entire benefit-to-risk profile of the patient. Moreover, they say clinical decisions should be made by the health care provider for each of his or her patients.

In a review, published in The American Journal of Medicine, researchers take a closer look at both the potential benefits and risks of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs) – such as ibuprofen, as well as aspirin for the selection of OTC drugs to treat mild symptoms of COVID-19.

Traditional nonspecific NSAIDs such as the shorter acting ibuprofen and longer acting naproxen have been used to treat COVID-19. These widely used OTC drugs reversibly and non-specifically inhibit both cyclooxygenase enzyme isoforms. This results in systematic reduction in the synthesis of prostaglandins resulting in anti-inflammatory and fever-reducing effects. The researchers caution, however, that both ibuprofen and naproxen have similar but greater side effect profiles than aspirin, such as gastroenteritis and peptic ulcers.

Acetaminophen is one of the most frequently used OTC drugs in the U.S. and worldwide as a treatment for fever, allergic symptoms, headaches, myalgia, symptoms of the common cold, and most recently COVID-19. Acetaminophen was originally marketed as an alternative to aspirin for treatment of mild to moderate pain based on reduced mucosal gastrointestinal side effects. The authors caution that even at daily doses of 4,000 milligrams per day, generally accepted as safe for adults, acetaminophen can be toxic to the liver and may result in the onset of acute liver failure. In the U.S., acetaminophen is the leading reason for calls to Poison Control Centers with more than 100,000 cases per year. These circumstances account for more than 2,600 hospitalizations and 450 deaths in the U.S. due to acute liver failure. 

Aspirin, or acetylsalicylic acid, inhibits the production of prostaglandins, which are responsible for mediating pain, inflammation and fever. The authors say that the beneficial effects of aspirin include anti-platelet, analgesic, antipyretic or anti-fever and anti-inflammatory properties. Aspirin is rapidly absorbed when taken orally and has a half-life of around four hours, after which it is mostly metabolized by the kidneys.

The researchers note that the anti-inflammatory benefits of aspirin should provide symptomatic relief of fever and body aches in COVID-19. They underscore, however, that health providers should view these in the context of the increased risks of bleeding, principally gastrointestinal. Further, COVID-19 itself may already predispose individuals to bleeding as well as to clotting abnormalities.

“We believe that health care providers should make individual clinical judgments for each of his or her patients in the selection of OTC drugs to treat symptoms of COVID-19. This judgement should be based on the entire benefit to risk profile of the patient,” said Charles H. Hennekens, M.D., Dr.PH, senior author, first Sir Richard Doll Professor and senior academic advisor in FAU’s Schmidt College of Medicine. “It is our belief that the individual health care provider knows far more about each of his or her patients than anyone, including expert members of guideline committees.”

The authors conclude that when the totality of evidence is complete, health care providers can make the most rational individual clinical judgements for their patients and policymakers for the health of the general public.

The authors believe that, at present, the totality of evidence is incomplete and requires reliable evidence from large- scale randomized trials designed a priori to do so, which is necessary to develop rational guidelines. They also believe that any guidelines should provide only guidance to health care providers. Currently, these considerations pose new clinical challenges for health care providers in prescribing OTC drugs to treat COVID-19. 

“The astute and judicious individual clinical decision making of health care providers for each individual patient based on all these considerations has the potential to do far more good than harm. Finally, guidelines should provide guidance to individual health care providers,” said Hennekens.

Study co-authors are Gage Collamore, a second-year medical student; Mark J. DiCorcia, Ph.D., an associate professor and associate dean for educational affairs and admissions; Yash Nagpal, a second-year medical student; and Larry Fiedler, M.D., a board certified gastroenterologist and an affiliate associate professor, all within FAU’s Schmidt College of Medicine; Michael A. Garone, M.D., a board-certified gastroenterologist and clinical assistant professor at George Washington University Hospital; and David L. DeMets, Ph.D., emeritus Halperin Professor and founding chair of biostatistics and informatics; and Dennis G. Maki, M.D., the Ovid O. Meyer Professor of Medicine; both at the University of Wisconsin School of Medicine and Public Health.

Hennekens and Maki served for two years as lieutenant commanders in the U.S. Public Health Service as epidemic intelligence service (EIS) officers with the CDC. They served under Alexander D. Langmuir, M.D., who created the EIS and directed the epidemiology program at the CDC, as well as Donald A. Henderson, M.D., chief of the Virus Disease Surveillance Program at the CDC. Langmuir and Henderson made significant contributions to the eradication of polio and smallpox using widespread vaccinations and public health strategies of proven benefit and had extraordinary collaborations with local, state, federal and international health authorities.
