A buildup of coronavirus in the lungs is likely behind the steep mortality rates seen in the pandemic, a new study finds. The results contrast with previous suspicions that simultaneous infections, such as bacterial pneumonia or overreaction of the body’s immune defense system, played major roles in heightened risk of death, the investigators say. Led

A nationwide US study has shown that the rate of opioid-related cardiac arrests has steeply risen and is now on par with the rate of cardiac arrest from other causes. The research is presented at ESC Congress 2021. Opioid use disorder, which includes dependence and addiction, affects more than two million people in the US,

Miami-Dade County Public Schools superintendent Alberto Carvalho oversees the fourth-largest school district in the U.S., and last week, in response to DeSantis' threats regarding paychecks, he told CBS Miami, "At no point shall I allow my decision to be influenced by a threat to my paycheck, a small price to pay considering the gravity of this

In some children with acute myeloid leukemia, cancer cells have as many DNA changes as healthy blood stem cells. Researchers were surprised to find these children have a poorer chance of survival compared with children whose leukemia has an above-average number of DNA changes. Their new study offers insight into how this form of blood

A KAIST immunology research team found that a specific subtype of macrophages that originated from blood monocytes plays a key role in the hyper-inflammatory response in SARS-CoV-2 infected lungs, by performing single-cell RNA sequencing of bronchoalveolar lavage fluid cells. This study provides new insights for understanding dynamic changes in immune responses to COVID-19. In the

Alzheimer’s disease (AD), the most common type of dementia, causes the death of neurons and leads to shrinking of the brain. Patients with AD will eventually experience gradual deterioration in memory, thinking, behavior and the ability to perform everyday activities. Yet, scientists do not fully understand what causes this disease. A recent study conducted by

People over the age of 60 living in the UK and the US who had more virtual contact during the pandemic actually experienced a greater increase in loneliness, new research finds. The study showed a notable increase in loneliness in the US and a decline in general mental well-being in the UK following the outbreak

(HealthDay)—Primary care physicians have been the largest provider of vaccinations for older individuals, according to a study published online in the July 1 issue of the Annals of Family Medicine. Elizabeth Wilkinson, from the Robert Graham Center for Policy Studies in Family Medicine and Primary Care in Washington, D.C., and colleagues used 2017 Medicare Part

A US federal judge on Monday upheld a university’s decision to require its students and employees to get vaccinated against COVID-19, the first ruling on an increasingly divisive issue ahead of the new school year. The decision by Judge Damon Leichty of the South Bend court, around 75 miles (120 kilometers) east of Chicago, can

Most countries have not introduced nationwide prostate-cancer screening, as current methods result in overdiagnoses and excessive and unnecessary biopsies. A new study by researchers at Karolinska Institutet in Sweden, which is published in the New England Journal of Medicine, indicates that screening by magnetic resonance imaging (MRI) and targeted biopsies could potentially cut overdiagnoses by

People who get type 2 diabetes need to gain control of their blood-sugar levels—fast. The years immediately after diagnosis are strikingly critical in terms of their future risk for heart attacks and death. This is shown by a joint study from the Universities of Gothenburg and Oxford. In a collaboration between the University of Gothenburg

In a new report now published on Scientific Reports, Irini Gerges and a team of scientists in Italy and the U.S. studied the importance of biomechanical and biochemical cues to create culture conditions suited for three-dimensional (3D) regenerative microenvironments and soft tissue formation. The team observed changes in adipogenesis relative to the 3D mechanical properties

The Delta variant of coronavirus is driving the pandemic forward in Africa at record speeds, the World Health Organization (WHO) warned on Thursday. Infection numbers have increased in Africa for six weeks running, rising by a quarter week-on-week to almost 202,000 in the week that ended Sunday, it said. The continent’s weekly record currently stands

Residents of Perth in Australia’s west woke to a four-day snap lockdown Tuesday, making it the country’s third major city under stay-at-home orders as the contagious Delta variant spreads. Just three positive cases have been diagnosed in Perth since the outbreak was detected but local health officials have long taken a highly cautious approach to

A team of scientists from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has now discovered that the odorant receptor OR5K1 is specialized to recognize pyrazines in both humans and domesticated animals. These are volatile substances that contribute to the typical odor of many vegetables or are formed when food

The World Health Organization voiced alarm Friday at surging COVID-19 cases across Africa, with the spread of new more contagious variants even as vaccination rates remain dangerously low. “It’s a trajectory that is very, very concerning,” WHO’s emergencies chief Michael Ryan told reporters from the organisation’s headquarters in Geneva. According to WHO data, the number

If you have watched TV since the 1990s, the sitcom theme song, “I’ll Be There for You,” has likely been stuck in your head at one point or another. New research from UC Davis suggests these experiences are more than a passing nuisance—they play an important role in helping memories form, not only for the

It had been a long four years since that July night when Marianne Sarcich first felt the lump in her right breast as she toweled off from a shower. Breast cancer. The cancer was caught early enough that it had not spread to other parts of her body, but doctors said she would need a

The new moon may come once a month, but it is a very important time for those who follow astrology closely. The new moon is said to be the perfect time of the month to set new intentions and goals for yourself and invite any positive changes you would like to see happen in your

In an analysis of patients on hemodialysis in New York City, there were substantial racial/ethnic disparities in COVID-19 rates that were not explained by neighborhood social vulnerability. The findings appear in an upcoming issue of JASN. The COVID-19 pandemic has disproportionately affected socially disadvantaged groups, including Black and Hispanic individuals, those with limited English proficiency,
