AIMBE Fellows' Efforts to Combat COVID-19 Outbreak
AIMBE Fellows and the medical and biological engineering community have been deeply involved in responding to the COVID-19 pandemic, and we are honored to share and recognize their efforts.

Decreasing the Time from Antibody Idea to IND Approval

Ram Sasisekharan | Via Genetic Engineering & Biotechnology News | May 26, 2020

In 2015, Ram Sasisekharan, PhD, the Alfred H. Caspary professor of biological engineering and health sciences & technology at MIT, founded Tychan. The company concentrates on one key goal: decreasing the time from antibody idea to investigational new drug (IND) approval. Now, the company claims it can cut the average time in half and more.

“With traditional technology, it usually takes about 18 months to get an antibody into human trials, from discovery to development,” Sasisekharan said. “For the Zika and Yellow Fever viruses, we developed new antibodies that went into human trials in less than nine months.” This new speed arises from a combination of informatics and bioprocessing… Continue reading.

Prophylactic Drug Delivery System for COVID-19

Heather Sheardown | Via McMaster University | May 22, 2020

The Heather Sheardown lab (McMaster University, Canada) is home to an interdisciplinary team of scientists and trainees with expertise in ophthalmology, polymer and biomaterial engineering, chemistry, pharmaceutical formulation and drug delivery, animal/ex-vivo/in-vitro models of disease and drug delivery, early stage material design and synthesis, and synthetic method scalability optimization.

As the availability of a SARS-CoV-2 vaccine is still far off, there is an immediate global need for prophylactic prevention strategies, particularly for vulnerable populations including seniors and frontline workers. The Sheardown lab has developed a mucoadhesive polymeric micelle that allows for the encapsulation of a range of therapeutics, providing local, controlled delivery to mucosal surfaces. This technology overcomes traditional solubility concerns, allowing formulations at higher drug concentrations. Its mucosal binding significantly reduces dosing frequency, increases local bioavailability and improves clinical efficacy. Developed and validated for safety and efficacy in the eye, this system is now being repurposed for the mucosa of the respiratory tract, formulated as a nasal spray or inhaled aerosol, incorporating two treatments that are currently under study internationally: hydroxychloroquine (HCQ) and remdisivir… Continue reading.

Go behind the virus on its entry way with targeted pharmacological therapy: the inhalation route of anti SARS-Cov2 active substances.

Ruggero Bettini | Via AIMBE Public Documents | May 21, 2020

BACKGROUND

SARS-Cov2 is the last appeared coronavirus that developed a pandemic infection with huge number of fatal cases. No vaccines are yet available that protect from this infection. However, a number of therapeutic tactics against COVID-19 have been empirically started.

According to Mehra et al., 2020, in COVID-19 illness, a structured approach to clinical is imperative (1). Such approach distinguish the phase in which the viral pathogenicity is dominant, from the phase where the host inflammatory response overtakes the pathology. Therefore, after five months of epidemy, 3-stage’s progression of illness, corresponding to increasing severity with distinct clinical signs, therapy responses and clinical outcomes, has been assessed. These stages constitute the reference for investigation and proposition of effective targeted therapies (1).

Stage I is the phase where the early infection causes to most people mild or asymptomatic disease. Treatment at this level with drug having antiviral activity could prevent the progression to severe disease. Stage II (moderate) corresponds to the pulmonary involvement without (IIa) and with (IIb) hypoxia. In this stage the pulmonary disease is established with viral lung multiplication and localized inflammation. The patients develop a viral pneumonia, with cough, fever and possibly hypoxia. Now, not only antiviral drugs are required but, in particular, the inflammation has to be considered and treated. Stage III is the phase in which an extra-pulmonary systemic hyperinflammation syndrome manifests. Likely, a minority of Covid-19 patients transit to this stage where the therapy is essentially against the so called “inflammation storm… Continue reading.

UC Davis Engineering Projects Fight COVID-19

Cristina Davis | Via UC Davis | May 20, 2020

SARS-COV-2, also known as COVID-19, uses its spike proteins to bind with cells. Using antibodies or an enzyme like ACE2-FC to bind with the spike proteins is key to preventing further infection. Graphic courtesy of Roland Faller.

With new seed grants from the UC Davis Office of Research’s COVID-19 Research Accelerator Funding Track (CRAFT), three teams of UC Davis engineers are applying their expertise toward the pandemic response to help people become safer, healthier and better-tested.

Mechanical and aerospace engineering (MAE) professor and chair Cristina Davis and chemical engineering (CHE) faculty Priya Shah, Karen McDonald and Roland Faller received $25,000 project awards for research that rapidly generates new insights about COVID-19, while biological and agricultural engineering (BAE) professor Gang Sun received a $5,000 small award to apply current research to the pandemic response. These proposals were chosen out from more than 100 applications and were awarded with the expectation that these projects will lead to larger collaborations.

Using Breath to Predict COVID-19 Cases

MAE professor Cristina Davis and her team are using portable devices that capture people’s breath to look for chemical and biological markers, known as biomarkers, to identify and predict the severity of COVID-19 infections.

Davis’ lab produces portable chemical sensing devices that record chemicals from the air or a person’s breath using mass spectroscopy. As part of an ongoing project with professor Nick Kenyon and associate professor Michael Schivo at the UC Davis Medical Center, the team had been conducting a clinical study with these devices to try to find early, asymptomatic biomarkers for the flu. When the pandemic began, the shift to COVID-19 was an obvious one… Continue reading.

Researchers Receives NIH Funds for Adjuvant Research to Boost Coronavirus Vaccines

Krishnendu Roy | Via Georgia Tech | May 20, 2020

Researchers have received funding from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, to screen and evaluate certain molecules known as adjuvants that may improve the ability of coronavirus vaccines to stimulate the immune system and generate appropriate responses necessary to protect the general population against the virus.

“The adjuvants that we are studying, known as pathogen-associated molecular patterns (PAMPs), are molecules often found in viruses and bacteria, and can efficiently stimulate our immune system,” explained Krishnendu Roy, a professor and Robert A. Milton Chair in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. “Most viruses have several of these molecules in them, and we are trying to mimic that multi-adjuvant structure… Continue reading.

Johns Hopkins researchers to use machine learning to predict heart damage in COVID-19 victims

Natalia Trayanova | Via Johns Hopkins University | May 18, 2020

Johns Hopkins researchers recently received a $195,000 Rapid Response Research grant from the National Science Foundation to, using machine learning, identify which COVID-19 patients are at risk of adverse cardiac events such as heart failure, sustained abnormal heartbeats, heart attacks, cardiogenic shock and death.

Increasing evidence of COVID-19’s negative impacts on the cardiovascular system highlights a great need for identifying COVID-19 patients at risk for heart problems, the researchers say. However, no such predictive capabilities currently exist.

“This project will provide clinicians with early warning signs and ensure that resources are allocated to patients with the greatest need,” says Natalia Trayanova, the Murray B. Sachs Professor in the Department of Biomedical Engineering at The Johns Hopkins University Schools of Engineering and Medicine and the project’s principal investigator… Continue reading.

Carlsbad biotech to test drug that targets gut in COVID-19 patients

Geert Schmid-Schönbein | Via San Diego Union Tribune | May 15, 2020

Leading Biosciences hopes that its drug will keep digestive enzymes from spilling into the bloodstream and triggering the airway inflammation seen in COVID-19

COVID-19’s worst symptoms are felt in the lungs — where the airways of some patients fill with dead cells and fluid, triggering a deadly spiral of inflammation. A local biotech company thinks it can treat these symptoms by targeting a completely different part of the body: your gut.

Leading Biosciences received permission from the Food and Drug Administration on Friday to test whether its drug, designed to shore up the intestine’s natural barrier, helps severe COVID-19 patients breathe on their own and recover sooner.

It’s an unorthodox-sounding approach, but it’s based on the idea that many diseases — including COVID-19 — are connected to what happens in the gut… Continue reading.

Northeastern Professor Partners With Audax Medical Inc., to Combat Covid-19

Tom Webster | Via Northeastern University | May 12, 2020

The Problem At Hand

The COVID-19 pandemic has changed many aspects of daily modern life; employees work from home, students attend class online, and individuals have been encouraged to stay inside, only leaving isolation for the essentials. The response has provided a mild reprieve from the rapid spread of the virus, though it is a temporary solution to a problem without a clear end in sight. Companies, universities and research labs involved in the health sciences across the world have shifted their focuses to combating COVID-19 and viral outbreaks to provide a better, more permanent solution for overcoming pandemic.

Recently, alongside Stanford University, Harvard University, and the Massachusetts Institute for Technology, the Center for Research Innovation at Northeastern University announced their support of the COVID-19 Technology Access Framework, which is a set of licensing principles that aims to make technologies that could aid research in preventing, diagnosing and treating COVID-19 more available. We took a moment to talk to Thomas Webster, a faculty researcher at Northeastern, about his work on one of these technologies.

The Inventor

Webster is a Professor at the College of Engineering at Northeastern University and heads a research lab responsible for researching and developing advanced nano-molecular technology that he calls the “Nano-Medicine Lab.” Earlier this month, Audax Medical, Inc., a Massachusetts-based company dedicated to developing medical innovations, licensed a technology developed in Webster’s lab that utilizes a nano-molecular approach to viral therapy… Continue reading.

Alternative to the Handshake Developed by UConn Doctors

Cato Laurencin | Via UConn Today | May 12, 2020

Did you know a single handshake can transfer 124 million bacteria?

That’s why in the midst of the global COVID-19 pandemic in the journal Science’s Editor’s Blog entitled “The end of the handshake?,” UConn Health doctors are recommending a new alternative to the handshake to reduce human contact, protect public health, and diminish the spread of the coronavirus.

With hand-to-hand contact now strongly discouraged, and even the popular elbow bump now considered a breeding ground for germs due to the common practice of sneezing and coughing into the elbow region, Dr. Cato T. Laurencin and Dr. Aneesah McClinton of UConn Health’s Connecticut Convergence Institute for Translation in Regenerative Engineering have created “The Laurencin-McClinton Greeting” (LMG) to meet the evolving COVID-19 culture needs… Continue reading.

Coventor-A COVID-19 Ventilation System

Arthur Erdman | Via Earl E. Bakken MDC | May 12, 2020

In response to COVID-19, the Earl E. Bakken Medical Devices Center has built a homemade ventilator. This device represents a rapidly scalable opportunity for healthcare providers to provide life sustaining mechanical ventilation to patients for whom no other option currently exists. The mechanical ventilator is simple to use for ICU-trained medical providers, it is compact (the size of a cereal box) and relatively inexpensive to manufacture and distribute. This device does not require a pressurized oxygen or air supply unlike commercially available mechanical ventilators.

In collaboration between the University of Minnesota, local industry leaders, and individual donors, we are able to acquire the necessary components for prototypes required to test and prove the concept. The team is hoping to ramp up and provide enough ventilators to help alleviate the stress on the healthcare system in the wake of COVID-19. All ventilators will currently ship from Minneapolis, Minnesota.

Your gift will benefit the Earl E. Bakken Medical Devices Center educational, research, and outreach programs, with the main priority right now being the COVID-19 ventilator project.

COVID-19 Puts Spotlight on Artificial Intelligence

Russ Altman | Via Genetic Engineering & Biotechnology News | May 11, 2020

As the COVID-19 pandemic continues to infect people across the world, a technological application already familiar to many in the biotech field is lending a key supporting role in the fight to treat and stop it: artificial intelligence (AI).

AI is currently being used by many companies to identify and screen existing drugs that could be repurposed to treat COVID-19, aid clinical trials, sift through trial data, and scour through patient electronic medical records (EMRs). The power of AI in COVID-19 is that it is being used to generate actionable information—some of which would be impossible without AI—much more quickly than before.

A simple definition of AI is the ability of a computer to rapidly think and learn. AI utilizes machine learning to analyze large amounts of data. It can also model predictions, screen virtually and develop insights that can be used to advance R&D and make patient medical assessments… Continue reading.

manufactured with six hours of skilled labor for less than $1,000 per unit
(Photo by UNC-Chapel Hill)

Biomedical engineering student Kathlyne Bautista always knew that her coursework and training would set her on a path to make a life-changing difference for people. But before the coronavirus pandemic, she didn’t realize just how soon that opportunity would arrive.

Bautista is part of the Carolina Respiratory Emergency – Ventilator (CaRE-Vent) team led by Dr. Yueh Lee, MD, an associate professor at the University of North Carolina at Chapel Hill. His research team is sprinting to design and prototype an open-source ventilator in a matter of weeks that has the potential to help fill a critical equipment gap caused by a projected spike in COVID-19 patients. The group is designing the ventilator so that it could be manufactured quickly and inexpensively – at less than $1,000 and with only six hours of skilled labor per unit.

And even in the best-case scenario – where the COVID-19 curve flattens to the point that the device is never needed for patients – the team’s efforts are advancing knowledge in the biomedical design community about the best way to create emergency ventilators in the future… Continue reading.

Carnegie Mellon, Pitt Researchers Launch Ventilator Project

Keith Cook | Via Carnegie Mellon University | May 6, 2020

Low-cost device could address current and future shortages

Researchers at Carnegie Mellon University and the University of Pittsburgh School of Medicine are developing a new, low-cost ventilator they say will address the ventilator shortage, both now and in the future, that has been made evident by the COVID-19 pandemic.

Dubbed Roboventilator, the device will employ CMU-developed robotic technologies and advanced sensors, filling the gap between the expensive sophisticated mechanical ventilators used in intensive care units and the current low-cost alternatives with limited capabilities being approved emergently by the Food and Drug Administration.

“We’ve already developed robotic and sensor technology that can detect force even as it drives an air pump,” said Howie Choset, professor of robotics at CMU. “When that is paired with air-management controls developed by Keith Cook, a CMU professor of biomedical engineering, we believe we can build a closed-loop system that can provide customized and appropriate ventilation to people with respiratory failure from COVID-19… Continue reading.

Researchers to develop AI to help diagnose, understand COVID-19 in lung images

Maryellen Giger | Via University of Chicago | May 6, 2020

UChicago, Argonne study hopes to learn to identify cases and guide treatment

As physicians and researchers grapple with a rapidly-spreading, deadly and novel disease, they need all the help they can get. Many centers are exploring whether artificial intelligence can help fight COVID-19, extracting knowledge from complex and rapidly growing data on how to best diagnose and treat patients.

One University of Chicago and Argonne National Laboratory collaboration believes that AI can be a helpful clinical partner for a particularly important kind of medical data: images. Because severe cases of COVID-19 most often present as a respiratory illness, triggering severe pneumonia in patients, chest X-rays and thoracic CT scans are a potential exam. With a grant from the new c3.ai Digital Transformation Institute, computer-aided diagnosis expert Maryellen Giger will lead an effort to develop new AI tools that use these medical images to diagnose, monitor and help plan treatment for COVID-19 patients… Continue reading.

The Covid Recovery Comes Down to Engineering

Guru Madhavan | Via Wall Street Journal | May 5, 2020

Don’t believe it? Look at the logistics required for the broadband everyone teleworking enjoys.

Reopening the country in the midst of a pandemic is akin to charging an enemy position at the top of a hill. Recovery and rebuilding will test us at every step with the risk of losing hard-won ground. But an old military insight can provide us with surer footing: amateurs talk tactics, professionals discuss logistics. Epidemiology established the right methods for fighting individual battles with Covid-19, from hand-washing to social distancing, but now it’s time to talk recovery logistics.

Much of the conversation will come back to engineering, which historically has advanced public health far more than medical care has. Sanitation, water supply, electrification, refrigeration,
highways, transportation safety, body scanning and mass production are a few examples. It’s easy to overlook how these technologies improve health outcomes, so consider one that’s an obvious part of many Americans’ lives today: the bandwidth necessary for telework… Continue reading.

NLM Highlights Essential Role of Clinical Databases in Pandemic

Patricia Brennan | Via GovernmentCIO Media | May 4, 2020

The National Library of Medicine is embarking on an extensive modernization effort of the world’s largest public clinical trial registry and results database, ClinicalTrials.gov, with the COVID-19 response underpinning the importance of the multi-year project.

“This effort to improve the user experience and update the technology platform is critically important for so many things that we do at NIH, our partnerships across the government and our commitment to the American public — the taxpayers and the research participants,” Kelly Wolinetz, associate director for the agency’s Office of Science Policy and NIH’s acting chief of staff, said in a virtual public meeting Thursday.

Additionally, although the novel coronavirus was discovered relatively recently — with the first full sequence of the virus published in NLM’s GenBank in mid-January — there are over 900 clinical trial studies for COVID-19 listed on the website, NLM Director Patricia Brennan noted.

“During this crisis, many libraries have closed and over the last five years many hospital libraries have restricted their services, so never before has the NLM been this important… Continue reading.

Protecting the Heart from COVID-19

Todd McDevitt | Via Gladstone Institutes | May 1, 2020

It’s well-known that COVID-19 affects the respiratory system, infecting healthy lung cells with the COVID-19 virus, but if it spreads to the heart it could become a much more deadly disease. A recent study found that in more than 10 percent of COVID-19 cases where heart damage occurred, there was no history of cardiovascular disease. Furthermore, a blood marker for heart damage (troponin) was the single best predictor of death, suggesting that heart damage is a key factor in mortality. Now the virus has been found in heart tissue, and the virus can infect human heart cells in a dish, stopping them from beating. Investigating the link between COVID-19 and damage to the heart is vital to preventing cardiovascular effects in future patients and perhaps finding a treatment for COVID-19 induced heart failure.

Senior Investigators Bruce Conklin, MD, and Todd McDevitt, PhD, are investigating how COVID-19 might damage the heart by asking two questions: How susceptible are the cells in the heart to infection by the virus, and what pharmaceuticals could be used to lessen damage to the heart or prevent the virus from infecting heart cells altogether… Continue reading.

OHIO researchers win grant to study treatment for possible fatal complications of COVID-19

Doug Goetz | Via Ohio University | April 30, 2020

Faculty researchers from Ohio University’s Heritage College of Osteopathic Medicine and Russ College of Engineering and Technology have received a $100,000 grant to investigate possible treatments for mitigating the severity of COVID-19.

Kelly McCall, Ph.D., and Douglas Goetz, Ph.D., will measure how effective a number of different chemical compounds are at preventing “cytokine storms,” a sometimes-fatal complication that can stem from COVID-19 infections.

The body responds to the presence of a pathogen by releasing a swarm of immune system proteins called cytokines to help fight off the virus or bacterium. If too many cytokines are released, a cytokine storm develops which can severely damage organs. This reaction is believed to be responsible for some of the deaths from COVID-19… Continue reading.

UC Davis Engineers, Clinician Develop Low-Cost, Portable Ventilator

Tingrui Pan | Via UC Davis | April 29, 2020

Engineers at the University of California, Davis, are working with clinicians to create a simple, inexpensive ventilator. They have developed a prototype and plan to make plans freely available online. Versions could be in clinical use in about six months. “This is a critical device to have. It provides the vital functions of a ventilator while being completely portable,” said Andrew Li, assistant professor in the Department of Surgery at UC Davis Health. The device, named “AmbuBox,” is based on the ambu-bag, a handheld ventilation device. Squeezing the bag by hand pushes air into a patient’s lungs.

There is a gap between the handheld ambu-bag and expensive ventilators used in intensive care units, said Tingrui Pan, professor of biomedical engineering at UC Davis. One attempt to fill this gap is MIT’s E-VENT project, but this device involves a number of mechanical moving parts… Continue reading.

Giving Distressed Lungs a Safer Fighting Chance

William Federspiel | Via Global Health News wire | April 28, 2020

A device designed at the University of Pittsburgh could help improve outcomes as a treatment for COVID-19 when used in conjunction with non-invasive or mechanical ventilation, and it recently received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration. Health records from a New York study showed that close to 90 percent of patients who were placed on mechanical ventilation did not survive. Some intensive care units are now considering mechanical ventilation as a last resort because of the complications and side effects associated with the process, and researchers believe this device could help.

The Hemolung Respiratory Assist System is a minimally invasive device that does the work of the lungs by removing carbon dioxide directly from the blood, much as a dialysis machine does the work of the kidneys. The device was developed by William Federspiel, PhD, professor of bioengineering at Pitt’s Swanson School of Engineering, and the Pittsburgh-based lung-assist device company ALung Technologies, co-founded by Federspiel… Continue reading.

Portable Microfluidic Platform Developed for Detecting Coronavirus Using Smartphone

Brian Cunningham | Via Genetic Engineering & Biotechnology News | April 24, 2020

Researchers headed by a team at the University of Illinois, Urbana-Champaign, have developed what they claim is an inexpensive, sensitive smartphone-based device that can detect viral and bacterial pathogens in about 30 minutes, and could be adapted to test for SARS-CoV-2. The platform comprises a cartridge-housed microfluidic chip that carries out isothermal amplification of viral nucleic acids from nasal swab samples, which are then detected using the smartphone camera. The investigators report on their use of the system to detect equine viruses as a non-biohazard surrogate for SARS-CoV-2, but say that when adapted to test for coronavirus, the smartphone accessory, costing about $50, could be used to reduce the pressure on testing laboratories during pandemics such as COVID-19.

“This test can be performed rapidly on passengers before getting on a flight, on people going to a theme park, or before events like a conference or concert,” said University of Illinois, Urbana-Champaign electrical and computer engineering professor Brian Cunningham, PhD, who, together with bioengineering professor Rashid Bashir, PhD, led the development of the device. “Cloud computing via a smartphone application could allow a negative test result to be registered with event organizers or as part of a boarding pass for a flight. Or, a person in quarantine could give themselves daily tests, register the results with a doctor, and then know when it’s safe to come out and rejoin society… Continue reading.

By simplifying testing, the researchers could put diagnostics into the hands of people everywhere — without the need for expensive laboratories or expertise. This could provide the large-scale testing required for ending stay-at-home orders, reopening the economy or preparing for a predicted virus resurgence in the fall… Continue reading.

4 Ways Engineers Aim to Save Lives During COVID-19

Mehmet Toner | Via Futurity | April 20, 2020

Researchers are pivoting their work to tackle the many engineering problems associated with the global coronavirus pandemic.

2. A NEW, FASTER COVID-19 TEST

Researchers are working to develop a rapid and reliable test for the SARS-CoV-2 virus.

The currently available tests look for the presence of SARS-CoV-2’s viral RNA, a unique and identifying genetic code. Building on previous research, the new test is fundamentally different: it detects and counts individual SARS-CoV-2 viruses by capturing them with antibodies.

The primary benefit of this approach is that its testing mechanism doesn’t require extensive sample preparation.

It also reduces the chance of false negative results. Viruses can mutate, but the currently available tests rely on knowing specific genetic sequences of the virus to detect it. So, if the coronavirus mutates within one of those sequences, a current test could report a false negative — which happened during the 2014 Ebola outbreak, making it difficult to accurately diagnose who was sick and contain the outbreak.

The new test uses a different set of supplies than the existing test, leaving it less prone to supply chain shortages than the current method, says Selim Ünlü, a professor of electrical, computer, materials science, and biomedical engineering, who is teaming up with John Connor, associate professor of microbiology at the School of Medicine, from the National Emerging Infectious Diseases Laboratories, and Mehmet Toner of Massachusetts General Hospital to develop the test… Read the full article.

BU Engineers Are Taking on the Coronavirus Pandemic

Joyce Wong | Via Boston University | April 17, 2020

Across Boston University’s School of Engineering, researchers are pivoting their work to tackle the many engineering problems associated with the global coronavirus pandemic.

“I’m glad I’m an engineer right now,” says Joyce Wong, professor of biomedical and materials science engineering. “There are so many problems that need to be solved in this crisis and I can actually use my expertise to help.”

Wong, like many other engineers and researchers, is diving in to do what she can to mitigate the COVID-19 pandemic. These efforts are in addition to the first wave of help, across BU’s Charles River and Medical Campuses, that gathered personal protective equipment (PPE) from labs—shuttered by Governor Charlie Baker’s stay-at-home advisory—to donate to healthcare workers in Massachusetts. Here are four ways that BU engineers are using technology to tackle the coronavirus pandemic:

1. New medical equipment

Wong started working on two projects after talking to her cousin, Steven Horng, an emergency medicine physician at Beth Israel Deaconess Medical Center (BIDMC).

“I started hearing about the PPE shortages from Steven, and then he started to tell me about more of the challenges healthcare workers are facing,” she says. “We’re getting close to the predicted peak of cases in Massachusetts, so I want to help out any way I can… Continue reading.

BU Engineers Are Taking on the Coronavirus Pandemic

Catherine Klapperich | Via Boston University | April 17, 2020

Across Boston University’s School of Engineering, researchers are pivoting their work to tackle the many engineering problems associated with the global coronavirus pandemic.

3. Speeding up test validation

Catherine Klapperich, director of the BU Precision Diagnostics Center and a professor of biomedical and materials science engineering, is spearheading a team to validate new types of SARS-CoV-2 tests. To contain the current COVID-19 pandemic, and prevent future relapses, an extreme ramp up of testing is needed across the United States. But there are currently roadblocks and shortages of supplies barring that from being possible. To increase testing capabilities, new tests, like Ünlü’s, must be evaluated and validated through FDA regulatory procedures. Those validations take time—so, Klapperich’s team is trying to speed up that process.

The Precision Diagnostics Center is taking on the task of preclinical lab validation of newly developed COVID-19 tests. First up, they’re working with one developed by Michael Springer’s systems biology group at Harvard Medical School… Continue reading.

2. A novel (and more rapid) COVID-19 test

Selim Ünlü, BU professor of electrical, computer, materials science and biomedical engineering, is teaming up with longtime collaborator John Connor, BU School of Medicine associate professor of microbiology, from the National Emerging Infectious Diseases Laboratories. Together with Mehmet Toner of Massachusetts General Hospital, the trio is working to develop a rapid and reliable test for the SARS-CoV-2 virus.

The currently available tests look for the presence of SARS-CoV-2’s viral RNA, a unique and identifying genetic code. Building on his previous research, Ünlü’s test is fundamentally different: it detects and counts individual SARS-CoV-2 viruses by capturing them with antibodies… Continue reading.

3D printed swabs developed at UofL to help fill gap in COVID-19 test kits

George Pantalos | Via University of Louisville | April 16, 2020

Innovation at the University of Louisville involving multiple departments at the university has led to a promising solution for the shortage of swabs in COVID-19 test kits. In response to a request from the Commonwealth of Kentucky, UofL’s Additive Manufacturing Institute of Science & Technology (AMIST), along with faculty and students in the Schools of Dentistry, Engineering and Medicine have created a 3D printed swab made of a pliable resin material.

“This effort adds to the list of our response during the pandemic, including 3D printed face shields, respirators and ventilators being manufactured through the expertise of our institute. We hope our work will provide the necessary tools for Kentucky, as well as our local health care facilities,” said Ed Tackett, director of workforce development at AMIST, which is part of the J.B.

PPE Patent Pending: Next Generation Custom-fitting Masks

Cato Laurencin | Via UConn Today | April 16, 2020

UConn is developing the latest innovative approach to tackling the personal protective equipment (PPE) shortage that has developed in the wake of the coronavirus pandemic, and it has already been used to protect front-line providers at UConn Health.

The Connecticut Convergence Institute for Translation in Regenerative Engineering has developed a method to fabricate custom-fit mask frames and exoskeletons to give conventional masks the optimal protective qualities of N95 respirators.

“We use a combination of facial recognition software and 3D printing to create the exact dimensions and make the perfect size,” says Dr. Cato T. Laurencin, the institute’s CEO. “It’s very difficult to make one-size fits all, and one size shouldn’t fit all… Continue reading.

Vapor H2O2 sterilization as a decontamination method for the reuse of N95 respirators in the COVID-19 emergency

Ebru Oral | Via MedRxIV | April 16, 2020

Abstract

There are a variety of methods routinely used in the sterilization of medical devices using hydrogen peroxide (H2O2) including vaporization, plasma generation and ionization. Many of these systems are used for sterilization and are validated for bioburden reduction using bacterial spores. Here, we explored the benefits of using vaporized H2O2 (VHP) treatment of N95 respirators for emergency decontamination and reuse to alleviate PPE shortages for healthcare workers in the COVID-19 emergency. The factors that are considered for the effective reuse of these respirators are the fit, the filter efficiency and the decontamination/disinfection level for SARS-CoV-2, which is the causative virus for COVID-19 and other organisms of concern in the hospital environment such as methicillin-resistant Staphylococcus aureus or Clostridium difficile. WE showed that the method did not affect fit or filter efficiency at least for one cycle and resulted in a >6 log reduction in bacterial spores and >3.8 log reduction in the infectious SARS-CoV2 load on N95 respirators… Read the full paper.

Chafing Against Regulation, Silicon Valley Pivots to Pandemic

Michael Jewett | Via Wired | April 15, 2020

Early in the evening on March 19, the prominent Silicon Valley investor and serial entrepreneur Balaji Srinivasan kicked off a tweet storm with a techno-libertarian call to arms:

“To all biotech & tech people: The Manhattan Project for the virus is going to end up being the Palo Alto Project. It’s on us. The state doesn’t have tech talent anymore. Can’t fix that overnight. But we can get them to legalize biomedical innovation with expanded right-to-try.”

Srinivasan did not respond to WIRED’S request for comment, but a subsequent tweet clarified that he was using the term Palo Alto Project to encapsulate the world of venture-backed “tech/biotech” companies that he envisions mobilizing to solve the mysteries of Covid-19 with the same awesome resolve with which J. Robert Oppenheimer and company cracked the atom… Continue reading.

Peptide Therapies Could Disable Coronavirus’ Spike Proteins

Sam Stupp | Via Northwestern University | April 13, 2020

Nanostructures could safely deliver a notoriously fragile drug to virus

Researchers are developing new peptide-based therapeutics for targeting and disabling the coronavirus’ so-called “spike proteins.”

Spike proteins — the crown of bulbous projections that give the coronavirus its signature halo effect — attach to and infect healthy cells, causing COVID-19. Led by Northwestern University and Massachusetts Institute of Technology (MIT), the research team is engineering a new nanostructured therapy that could potentially disable the virus and prevent its infection of human cells.

The idea is based on a recent discovery from the laboratory of Bradley L. Pentelute, an associate professor of chemistry at MIT. Pentelute’s team discovered a peptide molecule that specifically and strongly binds to the coronavirus’ spike protein… Continue reading.

Researcher unraveling SARS-CoV-2 spike protein through music

Markus Buehler | Via Phys.org | April 10, 2020

The proteins that make up all living things are alive with music. Just ask Markus Buehler: The musician and MIT professor develops artificial intelligence models to design new proteins, sometimes by translating them into sound. His goal is to create new biological materials for sustainable, non-toxic applications. In a project with the MIT-IBM Watson AI Lab, Buehler is searching for a protein to extend the shelf-life of perishable food. In a new study in Extreme Mechanics Letters, he and his colleagues offer a promising candidate: a silk protein made by honeybees for use in hive building.

In another recent study, in APL Bioengineering, he went a step further and used AI discover an entirely new protein. As both studies went to print, the Covid-19 outbreak was surging in the United States, and Buehler turned his attention to the spike protein of SARS-CoV-2, the appendage that makes the novel coronavirus so contagious. He and his colleagues are trying to unpack its vibrational properties through molecular-based sound spectra, which could hold one key to stopping the virus. Buehler recently sat down to discuss the art and science of his work… Continue reading.

UConn Researchers Find Blacks Are Disproportionately Impacted By COVID-19

Cato Laurencin | Via CT News Junkie | April 8, 2020

The team led by Dr. Cato T. Laurencin, former dean of the UConn School of Medicine, analyzed and reviewed the Department of Public Health’s data on COVID-19 outcomes and found that Blacks have a higher rate of infection and death in comparison to the percentage of the population they represent in the state.

However, the information collected on race and ethnicity is incomplete.

“The scarcity of this information generates a more substantial concern in which insufficiently identifying the affected may ultimately result in historically marginalized groups shouldering the greatest burden of disease and disproportionately bearing the social impact,” Laurencin and his team wrote in their paper… Continue reading.

Vitamin D3 may reduce severity of COVID-19 respiratory viral infection

Raphael Lee | Via BMJ Publishing Group | April 8, 2020

It is well established that the ubiquitously expressed master immune response transcription factor NF-κB is centrally involved in the pathogenesis of respiratory viral infections. [1] Indeed, COVID-19 is known to activate the NF-κB pathway that results in the upregulation of many inflammatory gene promoters. [2] It is postulated that this results from multiple catalytic interactions that occurs between the viral nucelocapsid proteins and NF-κB mediated immunomodulation. [3,4,5] This signaling dynamic is similar to the manner in which other highly fatal coronaviruses, such as MERS and SARS-COV, are known to take control of the NF-κB pathway. [6-8] The activation of the NF-kB pathway leads to the release of inflammatory mediators often linked to the systemic inflammatory response syndrome. [8]

Vitamin D3 (VD3) also is a regulator of NF-kB mediated cellular responses, It is known to inhibit the production of the proinflammatory cytokines TNFα, interleukins, and other key activators of the cellular immune defense. [9,10] VD3 promotes phenotypic shifting of lymphocytes towards an anti-inflammatory subsets. [11] Furthermore, data from clinical studies indicate that VD3 deficiency is clinically associated with increased susceptibility to respiratory viral infections and increased severity once infected. [12] In the case of respiratory syncytial virus, vitamin D3 increases synthesis of the NF-κB inhibitor, IκBα, resulting in decreased expression of pro-inflammatory genes… Continue reading.

Racial Profiling Is a Public Health and Health Disparities Issue

Cato Laurencin | Via Springer Link | April 6, 2020

Racial profiling is a public health and health disparities issue through its disparate and adverse health impact on those targeted by this practice, as well as members of their communities. We discuss six ways police profiling and racial discrimination adversely impact Black American health. We identify four direct and two indirect ways. Four direct ways are (1) violent confrontation with police that causes injury or death; (2) police language that escalates a confrontation through micro-aggressions or macro-aggressions; (3) sub-lethal confrontations with police; (4) adverse health consequences of perceived or vicarious threat, i.e., the mere belief in potential harm by police injures health. There are two indirect ways: (5) through knowledge of or personal relationship with someone who directly experienced racial profiling; (6) through public events without a personal knowledge of the unarmed person threatened or killed by police as a result of racial profiling, but where such events cause both individuals and the community at large to perceive a threat. We support recognition of racial profiling as a public health and health disparities issue. We recommend support for community programs that address the clinical health effects of racial profiling. We also recommend widespread engagement of trauma-informed policing (TIP) that acknowledges the clinical effects of racial profiling… Continue reading.

Cell-free Biotechnology Could Help Accelerate COVID-19 Therapeutics

Michael Jewett | Via Northwestern University | April 2, 2020

When it comes to fighting a fast-spreading pandemic, speed is critical.

Researchers at Northwestern Engineering and Cornell University have developed a new platform that could produce new therapies more than 10 times faster than current methods. The secret behind the platform’s unmatched speed is an unlikely tool: bacteria.

After taking the molecular machinery out of bacteria, the researchers then use that machinery to make a product, such as therapeutics, in a safe, inexpensive, and rapid manner. The idea is akin to opening the hood of a car and removing the engine, which allows researchers to use the engine for different purposes, free from the constraints of the car… Continue reading.

Robots to the Rescue: How They Can Help During Coronavirus (and Future Pandemics)

Guang-Zhong Yang | Via Singularity Hub | April 1, 2020

As the coronavirus pandemic forces people to keep their distance, could this be robots‘ time to shine? A group of scientists think so, and they’re calling for robots to do the “dull, dirty, and dangerous jobs” of infectious disease management.

Social distancing has emerged as one of the most effective strategies for slowing the spread of COVID-19, but it’s also bringing many jobs to a standstill and severely restricting our daily lives. And unfortunately, the one group that can’t rely on its protective benefits are the medical and emergency services workers we’re relying on to save us.

Robots could be a solution, according to the editorial board of Science Robotics, by helping replace humans in a host of critical tasks, from disinfecting hospitals to collecting patient samples and automating lab tests… Continue reading.

MIT initiates mass manufacture of disposable face shields for Covid-19 response

Elazer Edelman | Via MIT | April 1, 2020

The shortage of personal protective equipment (PPE) available to health care professionals has become increasingly problematic as Covid-19 cases continue to surge. The sheer volume of PPE needed to keep doctors, nurses, and their patients safe in this crisis is daunting — for example, tens of millions of disposable face shields will be needed nationwide each month. This week, a team from MIT launched mass manufacturing of a new technique to meet the high demand for disposable face shields.

The single piece face shield design will be made using a process known as die cutting. Machines will cut the design from thousands of flat sheets per hour. Once boxes of these flat sheets arrive at hospitals, health care professionals can quickly fold them into three-dimensional face shields before adjusting for their faces… Continue reading.

Coronavirus Testing Shouldn’t Be This Complicated

Catherine Klapperich | Via The Verge | March 30, 2020

Engineers have the technology to make it better

The US reported its first confirmed case of COVID-19 on January 21st. Eight weeks later, there still aren’t enough tests for the virus available for everyone who needs them. “It is a failing,” said Anthony Fauci, director of the National Institutes of Allergy and Infectious Diseases, at a House briefing last week. “The system is not really geared to what we need right now.”

People who are sick or have been in contact with sick people are struggling to get tested. Until last week, the number of tests that could be run per day in the United States was limited to around 7,000. Labs are struggling to get the supplies they need to meet the demand.

“If the health system is working well, those tests should be good and help us manage this epidemic,” says Catherine Klapperich, director of the Laboratory for Diagnostics and Global Healthcare Technologies at Boston University. “It’s frustrating that the testing we thought we could rely on didn’t roll out the way we expected it to… Continue reading.

Futuristic Technology Prints 1,000 Face Shield Components Per Day

Chad Mirkin | Via Northwestern University | March 30, 2020

Researchers hope to make a dent in hospitals’ need with a single 3D printer

Northwestern University researchers have demonstrated the ability to generate 1,000 components for face shields per day — with a single 3D printer.

A critical piece of personal protective equipment (PPE), face shields protect health care workers from the novel coronavirus (COVID-19) as they treat patients.

When Northwestern researchers Chad A. Mirkin and David Walker heard about the PPE shortage in hospitals, their team sprang into action. In October, Mirkin and his research group, in a breakthrough article in the journal Science, unveiled a new 3D printing technique called “high-area rapid printing” (HARP), a 13-feet-tall printer with a 2.5 square-foot print bed that can print about half a yard in an hour — a record throughput for the 3D printing field… Continue reading.
