Omicron: Number of vaccine breakthroughs in cancer patients on the rise, study finds
For cancer patients, COVID-19 poses a particular risk due to their often compromised immune systems. Now, a study shows that, due to Omicron, there is an increasing number of breakthrough infections in people with cancer, especially while they are un.....»»
New approach for delivery of anti-HIV antibody therapy shows promise in phase I clinical trial
A small phase I clinical trial has tested an anti-HIV strategy involving an adeno-associated viral vector-based gene delivery system that instructs cells to pump out antibodies that block HIV. In the trial of eight adults with HIV, the treatment was.....»»
Key to success of drug-resistant bacteria
Researchers have uncovered how Gram-negative bacteria -- which cause a variety of drug-resistant infections -- build their protective outer layer, which could lead to more effective treatments......»»
From computer to benchtop: Researchers find clues to new mechanisms for coronaviruses infections
A group of bat viruses related to SARS-CoV-2 can also infect human cells but uses a different and unknown entryway. While researchers are still honing in on how these viruses infect cells, the findings could help in the development of new vaccines th.....»»
Heart issues after COVID-19 uncommon in children and young adults, more research needed
The new scientific statement details what has been learned about how to treat, manage and even likely prevent cardiovascular complications from the SARS-CoV-2 virus in children and young adults, and calls for more research, including studies followin.....»»
SARS-CoV-2: Neutralization of BA.1 and BA.2 by therapeutic monoclonal antibodies
Scientists studied the sensitivity of Omicron BA.1 and BA.2 to nine monoclonal antibodies, some of which are used in pre-exposure prophylaxis in immunocompromised individuals. The scientists showed a loss of neutralizing activity against BA.1 and BA......»»
COVID-19 vaccine protects patients with inflammatory bowel disease from SARS-CoV-2
COVID-19 vaccines taken by people with inflammatory bowel disease (IBD), which affects millions worldwide, safely and effectively protects them from the SARS-Cov-2 virus, a study finds......»»
Heart inflammation rare among people hospitalized with COVID-19, study finds
A new study found that 54 out of nearly 57,000 adults (a rate of 2.4 of every 1,000) hospitalized due to COVID-19 infection developed acute myocarditis, an inflammation of the heart muscle often caused by viral infections. The study data was from the.....»»
From rare soil microbe, a new antibiotic candidate
Demand for new kinds of antibiotics is surging, as drug-resistant and emerging infections are becoming an increasingly serious global health threat. Researchers are racing to reexamine certain microbes that serve as one of our most successful sources.....»»
Why the WHO Took Two Years To Say COVID is Airborne
Early in the pandemic, the World Health Organization stated that SARS-CoV-2 was not transmitted through the air. That mistake and the prolonged process of correcting it sowed confusion and raises questions about what will happen in the next pandemic......»»
Scientific consortium provides real-time risk assessment of SARS-CoV-2 variants on immune protection
A new program has been set up to provide a real-time risk assessment of variants of SARS-CoV-2, the virus that causes COVID-19. The program assesses how the variants might affect transmission, virulence, and resistance to both disease-induced (conval.....»»
Easier, faster assay enables many more laboratories to identify COVID-19 variants
Using a commercially available test and simplified process, any laboratory that can run a real-time PCR assay can detect known SARS-CoV-2 variants in patient samples, researchers report......»»
NIH experts discuss controlling COVID-19 in commentary on herd immunity
Achieving classical herd immunity against SARS-CoV-2, the virus that causes COVID-19, may not be attainable, according to a new perspective article. However, widespread use of currently available public health interventions to prevent and control COV.....»»
German and Austrian deer thus far spared SARS-CoV-2 infections, unlike in North America
In North America, SARS-CoV-2 has spread from humans to white-tailed deer. The deer are now considered SARS-CoV-2 reservoirs and may even spill virus back to humans. Scientists have now shown that in Germany and Austria this has not happened as all de.....»»
Study shows COVID-19"s lingering impacts on the brain
Researchers have shown in detail how COVID-19 affects the central nervous system, according to a new study. The findings are the first comprehensive assessment of neuropathology associated with SARS-CoV-2 infection in a nonhuman primate model......»»
Are COVID-19-linked arrhythmias caused by viral damage to the heart"s pacemaker cells?
The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart's rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study. The findings offer a possible explanation for the heart ar.....»»
Pandemic"s urgency drove new collaborative approaches worldwide
In a new paper, nearly 130 authors from institutions around the world describe their groundbreaking collaborative work, 'Defining the risk of SARS-CoV-2 variants on immune protection.'.....»»
Aggressive warming during surgery does not reduce major complications
Patients kept at a body temperature of 37 C during major surgery had no fewer cardiac complications than patients kept at 35.5 C, according to new data. There were also no differences in the number of infections or required blood transfusions in pati.....»»
NIH begins trial of COVID boosters to fight future variants
The complex trial will test six booster regimens to broaden protection. Enlarge / A vial of the current Moderna COVID-19 vaccine. (credit: Getty | Ivan Romano) Mild or not, more SARS-CoV-2 variants are inevitable. To avoid any.....»»
How does an intestinal microbe become a pathogen?
The bacterium Escherichia coli is found in the human intestine, and elsewhere. There it is harmless, but in certain conditions it can become a pathogen. It can cause bladder infections or even sepsis. A team of researchers led by RESIST professor Mar.....»»
