Vaccinate big cats? New report shows SARS-CoV-2 Delta variant infecting endangered lions

There is evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infecting animals such as ferrets, fruit bats, and cats. New research led by Vijendra Pal Singh from the ICAR-National Institute of High Security Animal Disease in India suggests it might be time to vaccinate the big cats as well. Their report details SARS-CoV-2 infection in nine Asiatic lions caused by the SARS-CoV-2 Delta variant (B.1.617.2).

SARS-CoV-2 Lambda variant spreading rapidly in South America, report reveals

A new research paper by researchers in Peru describes a new variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) known as the Lambda variant (C.37). The Lambda variant was first reported in Lima, Peru, in December 2020, and from April 2021, nearly all the coronavirus infections in the country are caused by it.

Interleukin-6 antagonists benefit hospitalized patients with COVID-19

Findings from a study published today [6 July] in the Journal of the American Medical Association (JAMA) have prompted new World Health Organization (WHO) recommendations to use interleukin-6 antagonists in patients with severe or critical COVID-19 along with corticosteroids.

Study reveals the brain activity that underlies superagers' superior memory

As we age, our brains typically undergo a slow process of atrophy, causing less robust communication between various brain regions, which leads to declining memory and other cognitive functions. But a rare group of older individuals called "superagers" have been shown to learn and recall novel information as well as a 25-year-old.

Doctors advise against off-label use of new Alzheimer's medicine for cerebral amyloid angiopathy

A novel therapy recently approved by the U.S. Food and Drug Administration for patients with Alzheimer's disease amid considerable controversy should not be prescribed by physicians off-label for cerebral amyloid angiopathy (CAA), a similar cerebrovascular condition, according to Steven Greenberg, MD, PhD, director of the Hemorrhagic Stroke Research Program at Massachusetts General Hospital (MGH) and president of the International Cerebral Amyloid Angiopathy Association (ICAAA).

Study shows antibody titers after natural SARS-CoV-2 infection last longer than previously thought

A recent study by researchers from the United Kingdom (UK) revealed that antibody levels associated with protection against reinfection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are likely to last from 1.5 to 2 years on average and that the protection from severe infection may be present for several years.

COVID-19 vaccination may be stemming evolution of “fitter” SARS-CoV-2 variants

Researchers in the United States and India have presented the first known evidence that the rollout of coronavirus disease 2019 (COVID-19) vaccination is restricting the evolutionary and immune escape pathways accessible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Moderna’s COVID-19 vaccine elicits durable T cell memory and antibody responses

Researchers in the United States have shown that Moderna’s mRNA-1273 coronavirus disease 2019 (COVID-19) vaccine induces durable antibody and T cell responses to the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are comparable to those seen in cases of COVID-19 caused by natural SARS-CoV-2 infection.

New discovery provides clues to elucidate the pathogenesis of muscle diseases

A research collaboration based in Kumamoto University, Japan has discovered that muscles and the resident stem cells (satellite cells) responsible for muscle regeneration retain memory of their location in the body.

Long-term exposure to air pollutants increases the risk of dysmenorrhea in women

Dysmenorrhea, that is, frequent severe and painful cramps during menstruation from abnormal contractions of the uterus, is the most common of all gynecological disorders. It affects between 16-91% of girls and women of reproductive age, of whom 2%-29% have symptoms severe enough to restrict their daily activity.

Study quantifies the impact of loneliness in old age on life and health expectancy

In 1966, The Beatles cemented the plight of lonely older people in the popular imagination with the iconic 'Eleanor Rigby', a song that turned pop music on its head when it stayed at number one on the British charts for four weeks.

Study: TBI doesn't necessarily lead to an increased risk of marital instability

Traumatic brain injury (TBI) has a major impact on the lives of affected patients and families. But it doesn't necessarily lead to an increased risk of marital instability, as two-thirds of patients with TBI are still married to the same partner 10 years after their injury, reports a study in the July/August issue of the Journal of Head Trauma Rehabilitation.
