The COVID-19 pandemic, which claimed more than 336,000 lives in the United States in 2020, has significantly affected life expectancy, USC and Princeton researchers have found.

The researchers project that, due to the pandemic deaths last year, life expectancy at birth for Americans will shorten by 1.13 years to 77.48 years, according to their study published Thursday in the Proceedings of the National Academy of Sciences.

By feeding arctic ground squirrels special diets, researchers have found that omega-3 fatty acids, common in flax seed and fish oil, help keep the animals warmer in deep hibernation.

DURHAM, N.H.-- Waldenström macroglobulinemia (WM), a rare form of lymphoma, does not have any known cure and only one FDA-approved treatment making it challenging to treat patients. Researchers at the University of New Hampshire took the novel approach of targeting specific cell proteins that control DNA information using inhibitors, or drugs, that were effective in reducing the growth of the cancer cells and when combined with a third drug were even more successful in killing the WM cancer cells which could lead to more treatment options.

A clinical trial involving COVID-19 patients hospitalized at UT Health San Antonio and University Health, among roughly 100 sites globally, found that a combination of the drugs baricitinib and remdesivir reduced time to recovery, according to results published Dec. 11 in the New England Journal of Medicine. Six researchers from UT Health San Antonio and University Health are coauthors of the publication because of the San Antonio site's sizable patient enrollment in the trial.

Diabetes is characterized by elevated levels of sugar or glucose (hyperglycemia) in the blood. This occurs due to the lack of the hormone insulin in type 1 diabetes, and to reduced insulin levels in combination with insulin resistance in type 2 diabetes. A recent review of data supports stricter control of hemoglobin A1C levels (HbA1C) among pediatric patients with T1D. This review was led by Dr. Maria J. Redondo, pediatric endocrinologist at Texas Children's Hospital and professor at Baylor College of Medicine, in collaboration with Dr.

Researchers have developed a DNA test to quickly identify secondary infections in COVID-19 patients, who have double the risk of developing pneumonia while on ventilation than non-COVID-19 patients.

For patients with the most severe forms of COVID-19, mechanical ventilation is often the only way to keep them alive, as doctors use anti-inflammatory therapies to treat their inflamed lungs. However, these patients are susceptible to further infections from bacteria and fungi that they may acquire while in hospital - so called 'ventilator-associated pneumonia'.

DALLAS, Jan. 14, 2021 -- The longer the time between when heart attack symptoms start and a patient has an artery-clearing percutaneous coronary intervention (PCI), the more damage to the heart muscle, according to new research published today in Circulation: Cardiovascular Interventions, an American Heart Association journal.

DALLAS, Jan. 14, 2021 -- Adults who smoke or who are genetically predisposed to smoking behaviors are more likely to experience a serious type of stroke called subarachnoid hemorrhage (SAH), according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association. The results of this study provide important evidence that there is a causal link between smoking and the risk of SAH.

MEDFORD/SOMERVILLE (January 14, 2021) - A team of researchers led by engineers at Tufts University's School of Engineering and Stanford University's Program on Water, Health and Development have developed a novel and inexpensive chlorine dispensing device that can improve the safety of drinking water in regions of the world that lack financial resources and adequate infrastructure. With no moving parts, no need for electricity, and little need for maintenance, the device releases measured quantities of chlorine into the water just before it exits the tap.

Women who are young, "conventionally attractive" and appear and act feminine are more likely to be believed when making accusations of sexual harassment, a new University of Washington-led study finds.

That leaves women who don't fit the prototype potentially facing greater hurdles when trying to convince a workplace or court that they have been harassed.

In experiments in mouse tissues and human cells, Johns Hopkins Medicine researchers say they have found that removing a membrane that lines the back of the eye may improve the success rate for regrowing nerve cells damaged by blinding diseases. The findings are specifically aimed at discovering new ways to reverse vision loss caused by glaucoma and other diseases that affect the optic nerve, the information highway from the eye to the brain.

Patients with type 2 diabetes who follow a strict low carbohydrate diet for six months may experience greater rates of remission compared with other recommended diets without adverse effects, suggests a study published by The BMJ today.

The researchers acknowledge that most benefits diminished at 12 months, but say doctors might consider short term strict low carbohydrate diets for managing type 2 diabetes, while actively monitoring and adjusting diabetes medication as needed.

Non-invasive imaging technique called 31-phosphorus magnetic resonance spectroscopy used to measure mitochondrial function in patients with motor neuron disease (MND)

Evidence shows that mitochondria - often referred to as the cell's battery - are impaired in MND

This technique could be used to measure the effectiveness of future treatments for MND

Researchers from the Sheffield Institute for Translational Neuroscience (SITraN) have used a new imaging technique to measure the function of mitochondria in patients with motor neuron disease (MND).

A new paper in Q Open finds that the availability of fast food restaurants on the route between children's houses and their schools does not affect children's weight.

Reducing the rate of childhood obesity is a top public health priority in the United States where obesity rates are 18.4% for those ages 6-11 and 20.6% for those ages 12-19. Childhood obesity is a documented risk-factor for negative physical and mental health outcomes. Obese children are also more likely to become obese adults and suffer associated health problems.

While there is an abundant amount of research about traumatic brain injuries in athletes and those serving in the military, the same data is scarce when it comes to concussions and head and neck injuries sustained due to intimate partner violence.
