COVID-19 public health interventions reduced other respiratory infections

Wearing masks and quarantining while sick has helped mitigate the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). An indirect benefit of these efforts appears to be a decrease in flu cases and other respiratory infections. New research led by Lisa G. Winston of the University of California, San Francisco, confirmed COVID-19 public health interventions helped decrease the number of airborne viruses.

Around half of U.S. parents unwilling to vaccinate their children against COVID-19

A national online survey in March 2021 found only 49.4% of parents living in the United States were planning to vaccinate their child. A parents’ vaccination status and level of vaccine hesitancy were associated with adolescent vaccinations against COVID-19.

Moderna's COVID-19 vaccine elicits six-month antibody responses to variants

Researchers in the United States have demonstrated the long-term durability of the antibody responses elicited by Moderna’s mRNA-1273 vaccine against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Researchers investigate immune molecule that helps protect transplanted kidneys

Looking to improve organ transplant success, researchers are working to learn more about how an immune molecule, which also protects a fetus, helps protect some transplanted kidneys, and to develop a synthetic version of that molecule that could help more patients.

Study: No major difference in mortality between patients treated with drug-coated and non-drug-coated devices

Peripheral artery disease (PAD), or blockages in the arteries outside of the heart, affects more than 200 million people worldwide and 12.5 million people in the United States. Patients with this circulatory disorder may develop severe leg pain or unhealing wounds that require a minimally invasive revascularization procedure to open the blood vessels to improve blood flow.

New method can predict suicide risk

A team of Welsh academics has developed a new method of supporting health professionals to make clinical decisions about people who may be at risk of taking their own lives.

Type of heart failure may influence which approach is optimal for patients with AFib

Among patients with both heart failure and atrial fibrillation (AFib), treatment strategies focused on controlling the heart rhythm (using catheter ablation) and those focused on controlling the heart rate (using drugs and/or a pacemaker) showed no significant differences in terms of death from any cause or progression of heart failure.

Study shows how biases could be perpetuated by AI devices

Clinicians and surgeons are increasingly using medical devices based on artificial intelligence. These AI devices, which rely on data-driven algorithms to inform health care decisions, presently aid in diagnosing cancers, heart conditions and diseases of the eye, with many more applications on the way.

A promising drug delivery system for therapeutics that shut down harmful genes

Viruses attack the body by sending their genetic code -- DNA and RNA -- into cells and multiplying. A promising class of therapeutics that uses synthetic nucleic acids to target and shut down specific, harmful genes and prevent viruses from spreading is gaining steam.

Stabilizing mutations in SARS-CoV-2 immunogens improve vaccine design

Researchers in the United States have developed stabilized immunogens presenting the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may improve the scalability of RBD-based coronavirus vaccines.

Moderate therapeutic hypothermia does not improve neurological outcomes after cardiac arrest

In patients receiving therapeutic hypothermia after suffering out-of-hospital cardiac arrest, those who were cooled below 31 degrees Celsius (about 88 degrees Fahrenheit) for 24 hours showed no difference in terms of death or poor neurological outcomes at six months compared with patients receiving guideline-recommended cooling of 34 C (about 93 F).

Stair-climbing routines provide cardiovascular and muscular benefits to heart patients

A team of McMaster University researchers who studied heart patients found that stair-climbing routines, whether vigorous or moderate, provide significant cardiovascular and muscular benefits.

Sperm deliver signals to female reproductive tissues to increase the chances of conception

Sperm are generally viewed as having just one action in reproduction - to fertilize the female's egg - but studies at the University of Adelaide are overturning that view.

Sotagliflozin reduces adverse cardiovascular events across patients with diabetes, heart failure

Patients with both diabetes and heart failure who were treated with sotagliflozin, a novel investigational drug for diabetes, for a median of nine to 16 months experienced reductions of 22% to 43% in the risk of death or worsening heart failure compared with similar patients who were treated with a placebo

Dendritic cells can take a shortcut to reach the lymph nodes more quickly

In its response to pathogens and vaccines, our immune system relies on dendritic cells. These white blood cells patrol the body's tissues, collect components of pathogens and vaccines and transport them via lymphatic vessels to the nearest lymph node.

Abnormal blood levels of proteins linked to dementia, Alzheimer's disease

The development of dementia, often from Alzheimer's disease, late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health

Pirfenidone significantly reduces a marker of heart muscle scarring

Patients with heart failure with preserved ejection fraction who took the antifibrotic drug pirfenidone saw a significant reduction in a marker of heart muscle scarring compared with patients who received a placebo, based on findings from an early-phase trial presented at the American College of Cardiology's 70th Annual Scientific Session.

Omecamtiv mecarbil significantly reduces hospitalizations among patients with severe heart failure

The experimental heart failure drug omecamtiv mecarbil reduced heart failure hospitalizations by a greater margin among patients with more severely reduced ejection fraction, a measure indicating severe impairment in the heart's pumping ability, compared with those who had moderately reduced ejection fraction, according to research presented at the American College of Cardiology's 70th Annual Scientific Session.
