News at a glance: A win for obesity drugs, a new infectious disease institute head, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

COVID-19 and brain aging: what are the implications of immunosenescence?
Curr Aging Sci. 2022 Dec 28. doi: 10.2174/1874609816666221228103320. Online ahead of print.ABSTRACTThe human lifespan is increasing, and mankind is aging. It is estimated that, until the year 2050, this population worldwide will reach 22% of the total world population. Along with aging, the human immunologic system changes, a process called immunosenescence or even inflammaging. The aging immune system increases mortality and morbidity in the elderly mainly because it loses its capacity to react against internal and external aggressions. There is a decrease in B and T lymphocytes and CD4+ lymphocytes lose the CD28 protein ...

Evaluating feasibility, value and characteristics of an intergenerational friendly telephone visit program during the Covid-19 pandemic
Social isolation and loneliness are increasingly recognized as serious health risks for older Americans (1). Social isolation and loneliness are related forms of social disconnection that are associated with the incidence and worsening of anxiety and depressive disorders, coronary artery disease and stroke, dementia, and premature death (2-6). Thus, social distancing policies and isolation during the Covid-19 pandemic have uniquely impacted older adults.

Neurological Complications and Consequences of the Novel Coronavirus COVID-19 Infection in Elderly and Senile Patients (Literature Review)
AbstractBased on available publications, the article systematizes information about some forms of lesions of the central nervous system (CNS), their pathogenesis and clinical manifestations in the case of COVID-19. The risk factors, mechanisms of development, diagnostic approach, and the age characteristics of patients with neurological complications of COVID-19 are discussed. The specific mechanisms of the neuroinvasiveness and neurovirulence of the SARS-CoV-2 virus, regardless of the age of patients and the presence of risk factors, lead to systemic damage to the endothelium of small-caliber vessels, generalized thrombov...

Association of Delirium Incidence with Visitation Restrictions due to COVID-19 Pandemic in Patients with Acute Cerebrovascular Disease in a Stroke-Unit Setting: A Retrospective Cohort Study
Conclusion: Pandemic-associated visitation restrictions and specifically absolute visitation restrictions are associated with a higher incidence of delirium among stroke-unit patients with acute cerebrovascular disease. Benefit and harm of visitation restrictions should be carefully weighed and adjustments considered for patients otherwise at increased risk for delirium.Gerontology
