Socioeconomic status transition throughout life and risk of dementia

JAMA Network Open

2024-05-21
(Press-News.org) About The Study: This cohort study of Japanese older adults identified that upward and downward socioeconomic status transitions were associated with risk of dementia and the length of dementia-free periods over the lifespan. The results may be useful to understand the association between social mobility and healthy longevity.

Climbing the social ladder slows dementia, Japanese study reveals

Climbing the social ladder slows dementia, Japanese study reveals
2024-05-21
Osaka, Japan – Upward social mobility may ward off dementia, according to a new study. Dementia, a collective term for conditions marked by memory loss and diminished cognitive functioning, strains healthcare systems and devastates quality of life for patients and their families. Research thus far has found correlations between socioeconomic status (SES) – Parent’s asset, education level, income, and work status – and susceptibility to dementia, and SES changes throughout a person’s life, known as social mobility, seem to influence this risk; however, scientific ...

Researchers discover hidden step in dinosaur feather evolution

Researchers discover hidden step in dinosaur feather evolution
2024-05-21
Scientists discover ‘zoned development’ in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers New dinosaur skin fossil found to be composed of silica – the same as glass Discovery sheds light on evolution from scales to feathers Palaeontologists at University College Cork (UCC) in Ireland have discovered that some feathered dinosaurs had scaly skin like reptiles today, thus shedding new light on the evolutionary transition from scales to feathers. The researchers studied a new specimen of the feathered dinosaur Psittacosaurus from the early Cretaceous ...

Studies reveal cell-by-cell changes caused when pig hearts and kidneys are transplanted into humans

2024-05-21
Surgical teams at NYU Langone Health performed the world’s first genetically modified pig kidney transplants into a human body in September and November 2021, and then transplanted two pig hearts in the summer of 2022. These procedures were done in patients declared dead based on neurologic criteria (decedents) and maintained on ventilators with the consent of their families. Demonstrating the field’s progress, NYU Langone in April 2024 transplanted a pig kidney into a living patient. Now two new analyses, one published online on May 17 in Nature Medicine and the other May ...

SRI earns FDA Orphan Drug Designation for pancreatic cancer

2024-05-21
SRI’s Targeted Antigen Loaded Liposomes (TALL) — a treatment that expands the benefits of immunotherapy such as check-point inhibitors — has been granted Orphan Drug Designation (ODD) for pancreatic ductal adenocarcinoma (PDAC) by the U.S. Federal Drug Administration (FDA). As a result, SRI’s future strategic partners can gain tax credits for qualified clinical trials and potentially receive market exclusivity for a period of seven years after the drug’s approval, among other benefits. “FDA's orphan drug designation brings worthy attention to the demonstrated impact of SRI's TALL biotherapeutic for pancreatic cancer,” said Kathlynn Brown, ...

A new gene-editing system tackles complex diseases

A new gene-editing system tackles complex diseases
2024-05-21
The human genome consists of around 3 billion base pairs and humans are all 99.6% identical in their genetic makeup. That small 0.4% accounts for any difference between one person and another. Specific combinations of mutations in those base pairs hold important clues about the causes of complex health issues, including heart disease and neurodegenerative diseases like schizophrenia. Current methods to model or correct mutations in live cells are inefficient, especially when multiplexing — installing multiple point mutations simultaneously across the genome. Researchers from the University of California San Diego ...

Tracking down toxic metals from tobacco smoke

Tracking down toxic metals from tobacco smoke
2024-05-21
Cigarette smoke has been studied for years, revealing a multitude of contaminants, including toxic metals. But exactly which of those metals can be traced to secondhand or thirdhand smoke? Solving this problem has been a challenge for the research community because many of the metals found in tobacco smoke could also come from industrial or naturally occurring pollutants contaminating indoor and outdoor air. Now, a recent study by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has identified 28 trace metals in tobacco smoke. The findings reported in the journal ...

Clarifying the cellular mechanisms underlying periodontitis with an improved animal model

Clarifying the cellular mechanisms underlying periodontitis with an improved animal model
2024-05-21
TMDU researchers have developed a technique that allows a detailed analysis of periodontitis development over time Tokyo, Japan – Periodontal disease, represented by periodontitis, is the leading cause of tooth loss and affects close to one in five adults worldwide. In most cases, this condition occurs as a result of an inflammatory response to bacterial infection of the tissue around teeth. As the condition worsens, the gums begin to pull away, exposing teeth roots and bone. Notably, the incidence of periodontitis becomes more prevalent with age and with populations worldwide living ...

Age, race impact AI performance on digital mammograms

Age, race impact AI performance on digital mammograms
2024-05-21
OAK BROOK, Ill. – In a study of nearly 5,000 screening mammograms interpreted by an FDA-approved AI algorithm, patient characteristics such as race and age influenced false positive results. The study’s results were published today in Radiology, a journal of the Radiological Society of North America (RSNA). “AI has become a resource for radiologists to improve their efficiency and accuracy in reading screening mammograms while mitigating reader burnout,” said Derek L. Nguyen, M.D., assistant professor at Duke University in Durham, North Carolina. ...

Hope for a cure for visceral leishmaniasis, an often fatal infectious disease

Hope for a cure for visceral leishmaniasis, an often fatal infectious disease
2024-05-21
Hope for a cure for visceral leishmaniasis, an often fatal infectious disease     A discovery by Simona Stäger’s team could help come up with a treatment to the most serious form of leishmaniasis.   Leishmaniasis is a tropical disease affecting a growing number of people worldwide. Each year, between 700,000 and 1 million new cases are reported. Caused by a protozoan parasite of the genus Leishmania, which is transmitted to humans by the simple bite of a sand fly, leishmaniasis comprises three clinical forms, of which the visceral ...
