☆ What is a typical degree of cognitive ability for a person in their 80s?

How we change as we ageA decline in cognitive abilities is a normal part of healthy aging, said Dr. Emily Rogalski, Rosalind Franklin Professor of Neurology at the University of Chicago. A diagnosis of mild cognitive impairment is made clinically when cognitive difficulties become frequent and fall outside what is considered normal aging. “There’s not a whole lot of good evidence that there’s anything special about age 80 that leads to a drop-off” in cognitive abilities, Mather said. And they use cognitive tests, such as the Mini Mental Status Exam (MMSE) or Montreal Cognitive Assessment (MOCA), to assess performance in different cognitive areas. Although population-level data associates aging with cognitive decline, the actual manifestation of aging is very diverse on an individual level, Rogalski said.

☆ PrEPVacc: HIV vaccine trial that could be ‘the last roll of the dice’ this decade is underway

CNN —A novel trial that has been described as “the last roll of the dice” for a generation of HIV vaccines has entered its latter stages. Nearly 40 years since HIV was identified as the cause of AIDS, and 36 years since the first HIV vaccine trial, the medical community still does not have a working vaccine. But that is not necessarily why they were chosen to participate, said Eugene Ruzagira, PrEPVacc trial director. Evaluating the combination of a trial HIV vaccine and PrEP is a first, say organizers. “I did my very first HIV vaccine trial in 1991,” recalled Weber.

☆ Rosalind Franklin’s Role in DNA Discovery, Once Ignored, Is Told Anew in Song
▼ + stars: | 2023-05-29 | by ( Lauren Rosenfield | ) www.nytimes.com time to read: +1 min

During the summer of 2020, the composer and lyricist Madeline Myers spent hours at the piano in her Manhattan apartment as she struggled to write three songs for her new musical, “Double Helix,” about the British chemist Rosalind Franklin. The challenge wasn’t strictly about marrying words to a score, but conveying the science of a crucial moment in the discovery of DNA’s structure — and making the songs entertaining. Franklin’s experiments, in which she successfully used X-ray crystallography to create images of DNA, became the basis for James Watson and Francis Crick’s groundbreaking 1953 discovery of the double helix structure. The breakthrough underpins our modern understanding of genetics and biology, but for years Franklin received none of the credit. (She died of cancer in 1958 at the age of 37; her male colleagues were later awarded the Nobel Prize.)

☆ Opinion | Rosalind Franklin and Unsung Women in Science
▼ + stars: | 2023-05-09 | by ( ) www.nytimes.com time to read: +1 min

To the Editor:Re “Essay Extends Debate Over DNA Discovery” (Science Times, May 2):Determining the role that Rosalind Franklin played in the discovery of the structure of DNA remains a contentious issue. Lamentably, Dr. Franklin is often one of the few female scientists people can name as one who deserved more credit than she received during her lifetime. There are hundreds — if not thousands — of such unsung women throughout history. This has become increasingly evident to us as we work our way through our ever-increasing database of 250 deceased women of science. It might be true that today’s women are less likely to be shortchanged when it comes to receiving credit — and for that we are grateful.

☆ Steroid use for knee osteoarthritis may make it worse, studies say
▼ + stars: | 2022-11-29 | by ( Madeline Holcombe | ) edition.cnn.com time to read: +3 min

CNN —A common treatment for some arthritis pain might actually be making the condition worse, according to two new studies. Some of those patients didn’t receive any treatment and others got corticosteroid or hyaluronic acid injections, according to the studies. The takeaway from the studies is that corticosteroids should be administered with caution for osteoarthritis pain. “Perhaps hyaluronic acid injections need to be studied for pain management more thoroughly,” he said. And some people may not see significant benefit from either steroid or hyaluronic acid injections, Kim added.

☆ OMS: Vaccinarea, „depășită de variante”; Delta este prezentă acum în cel puțin 98 de țări
▼ + stars: | 2021-07-05 | by ( ) www.jurnal.md time to read: +3 min

Directorul general al OMS, spune că distribuirea vaccinurilor către țările sărace a fost „doar o scurgere, care este depășită de variante”, după ce datele arată că varianta Delta este prezentă acum în cel puțin 98 de țări. Avertismentul său vine după ce Dame Sarah Gilbert, profesorul de la Oxford care a condus echipa din spatele vaccinului Oxford/AstraZeneca, a cerut prudență cu privire la propunerile de vaccinare a copiilor din Marea Britanie. „Varianta Delta este periculoasă și continuă să evolueze, ceea ce necesită o evaluare constantă și o ajustare atentă a răspunsului la sănătatea publică”, a spus Ghebreyesus. „Delta a fost detectată în cel puțin 98 de țări și se răspândește rapid în țările cu acoperire de vaccinare scăzută și ridicată”. Acest punct a fost susținut de profesorul James Naismith, directorul Institutului Rosalind Franklin, Oxford.
