Previously Healthy Young Adults with ‘Long COVID’ Show Vascular Dysfunction in Limbs, but Not Brain

A first-of-its-kind study of young adults with positive COVID-19 tests from more than 4 weeks ago found that those who were still symptomatic (i.e., long-haulers) had impaired blood vessel function in their limbs, but not brains. Asymptotic participants had blood vessel function similar to controls.

Study: No Serious COVID-19 Vaccine Side Effects in Breastfeeding Moms, Infants

Researchers found that breastfeeding mothers who received either the Pfizer-BioNTech or Moderna vaccination reported the same local or systemic symptoms as what has been previously reported in non-breastfeeding women, with no serious side effects in the breastfed infants.

Second Breath: Region’s First Double Lung Transplant for COVID-19 Patient

After more than 50 days on advanced life support, a multi-disciplinary team at UC San Diego Health helps a patient who contracted COVID-19 become a candidate for a successful double lung transplant. The transplant surgery was the first in the region performed on a COVID-19 patient.

In transplant recipients, COVID-19 vaccines reduce infection and mortality risks

Vaccination against SARS-CoV-2 substantially lowers the risks of “breakthrough” infections and death due to COVID-19 in adult organ transplant recipients, according to a pair of research letters in Transplantation, the official Journal of The Transplantation Society and the International Liver Transplantation Society. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Study shows neutralizing antibodies to SARS-CoV-2 remain relatively high for up to 13 months following infection

  New York, NY – Researchers from the Icahn School of Medicine at Mount Sinai have found that most COVID-19 patients have persistent antibodies to the SARS-CoV-2 virus at levels that are correlated with neutralization of the virus more than…

Antibodies to SARS-CoV-2 Remain Stable, or Even Increase, Seven Months After Infection

The levels of IgG antibodies against SARS-CoV-2 Spike protein remain stable, or even increase, seven months after infection, according to a follow-up study in a cohort of healthcare workers coordinated by the Barcelona Institute for Global Health (ISGlobal), an institution supported by “la Caixa” Foundation, in collaboration with the Hospital Clinic of Barcelona.

UAH’s Baudry Lab part of half-million-dollar efforts to target COVID with drug therapies

Two different strategies to discover and perfect pharmaceuticals active against the COVID-19 virus have attracted a half million dollars in research funding to support five institutions, including the Baudry Lab at The University of Alabama in Huntsville (UAH).

利用人工智能筛选3000万种针对SARS-CoV-2的候选药物

妙佑医疗国际(Mayo Clinic)的研究人员和合作者利用计算机模拟和人工智能(AI)来筛选3000万种候选药物,这些药物有可能阻断导致COVID-19的SARS-CoV-2病毒。在一篇发表在《Biomolecules》上的论文中,研究人员阐述了他们如何加速药物发现,从而为开展进一步的研究确定最有希望的目标。他们的最终目的是寻找治疗COVID-19的新方法。

What if We Could Give Viruses a One-Two Punch?

Researchers at Stanford and Berkeley Lab’s Molecular Foundry have developed virus-killing molecules called peptoids. The technology could make possible an emerging category of antiviral drugs that could treat everything from herpes and COVID-19 to the common cold.

Scientists repurpose cancer and seizure medications to aid in the fight against COVID-19

Two teams of researchers using the Advanced Photon Source identified existing drugs — one used to treat cancer, the other an anti-seizure medication — that may work as treatments for COVID-19.

Imaging Test May Predict Patients Most at Risk of Some Heart Complications from COVID-19

Researchers at Johns Hopkins Medicine have shown that a type of echocardiogram, a common test to evaluate whether a person’s heart is pumping properly, may be useful in predicting which patients with COVID-19 are most at risk of developing atrial fibrillation — an irregular heartbeat that can increase a person’s risk for heart failure and stroke, among other heart issues. The new findings, published online May 30 in the Journal of the American Society of Echocardiography, also suggest that patients with COVID-19 who go on to develop atrial fibrillation more commonly have elevated levels of heart-related proteins called troponin and NT-proBNP in blood test samples.

Cutting out the proteins that give SARS-CoV-2 its power

Researchers at Texas Biomedical Research Institute (Texas Biomed) have narrowed down the proteins enabling SARS-CoV-2 to cause disease. Using advanced genetic engineering techniques developed at Texas Biomed, they systematically deleted the genetic code for five of the virus’s accessory proteins, one at a time, to see how each one affected the virus’s ability to spread and cause illness. The research was published online this month in the Journal of Virology.

UC San Diego Health Adopts SMART Health Card for Digital Vaccine Records

UC San Diego Health is now offering a verifiable digital vaccine record to its patients who have or will receive a COVID-19 vaccine. These secure online records, otherwise known as a SMART health card, can be accessed directly from the MyUCSDChart patient portal.

Study confirms the low likelihood that SARS-CoV-2 on hospital surfaces is infectious

A new study confirms the low likelihood that coronavirus contamination on hospital surfaces is infectious. The study is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs.

Virus that causes COVID-19 can find alternate route to infect cells

The virus that causes COVID-19 normally gets inside cells by attaching to a protein called ACE2. Researchers at Washington University School of Medicine in St. Louis have found that a single mutation confers the ability to enter cells through another route, which may threaten the effectiveness of COVID-19 vaccines and therapeutics designed to block the standard route of entry.

SARS-CoV-2 Worldwide Replication Drives Rapid Rise and Selection of Mutations

The number of COVID-19 variants is growing rapidly, so much that the scale and scope of mutation may pose a threat to the continuing successful use of the current vaccines and therapies. The findings, by an international team that includes University of California researchers, are being published in the June edition of the peer-reviewed journal EMBO Molecular Medicine. The pace of variation of the SARS-CoV-2 virus strains makes plain the threat that rapidly evolving new strains might give rise to escape variants, capable of limiting the efficacy of vaccines, therapies, and diagnostic tests.

Rapid exclusion of COVID-19 infection using AI, EKG technology

Artificial intelligence (AI) may offer a way to accurately determine that a person is not infected with COVID-19. An international retrospective study finds that infection with SARS-CoV-2, the virus that causes COVID-19, creates subtle electrical changes in the heart. An AI-enhanced EKG can detect these changes and potentially be used as a rapid, reliable COVID-19 screening test to rule out COVID-19 infection.

For Transplant Recipients, Third Time May Be the Charm for Better COVID Vaccine Protection

In a study published today in the Annals of Internal Medicine, Johns Hopkins Medicine researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 — the virus that causes COVID 19 — more than the standard two-dose regimen for people who have received solid organ transplants.

AI Predicts How Patients with Viral Infections, Including COVID-19, Will Fare

UC San Diego School of Medicine researchers discovered gene expression patterns associated with pandemic viral infections, providing a map to help define patients’ immune responses, measure disease severity, predict outcomes and test therapies — for current and future pandemics.

Will COVID-19 Eventually Become Just a Seasonal Nuisance?

Within the next decade, the novel coronavirus responsible for COVID-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles. That possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body’s immunity changes over time. Scientists at the University of Utah carried out the research, now published in the journal Viruses.

Organ Transplant Recipients Remain Vulnerable to Covid-19 Even After Second Vaccine Dose

In a study published today in the Journal of the American Medical Association (JAMA), Johns Hopkins Medicine researchers show that although two doses of a vaccine against SARS-CoV-2 — the virus that causes COVID 19 — confers some protection for people who have received solid organ transplants, it’s still not enough to enable them to dispense with masks, physical distancing and other safety measures.
