Lifestyle enrichment in later life and its association with dementia risk

JAMA Network Open

2023-07-14

(Press-News.org) About The Study: In this study of 10,000 older individuals in Australia, more frequent participation in adult literacy activities (taking education classes, using a computer, and writing letters or journals) and in active mental activities (playing games, cards, or chess and doing crosswords or puzzles) was associated with reduced dementia risk over 10 years. However, social outings and interactions were not associated with dementia risk.

Authors: Joanne Ryan, Ph.D., of Monash University in Melbourne, Australia, is the corresponding author.

NIH spent $8.1B for phased clinical trials of drugs approved 2010-19, ~10% of reported industry spending

2023-07-14

BENTLEY UNIVERSITY The U.S. National Institutes of Health (NIH) contributed $8.1 billion in project funding for phased clinical trials involving drugs approved by the FDA from 2010-2019, according to a new study from Bentley University’s Center for Integration of Science and Industry. The study, published in JAMA Health Forum, shows that NIH funding for clinical trials represents <3.5% of total NIH spending for basic or applied research related to these products and was significantly less than reported industry spending on clinical development. ...

Coordination could spare billions in grid upgrade costs and accelerate electrification

2023-07-14

The electric grids of the future will need to handle much bigger loads due to electrification of transportation and other sectors. This could mean expensive infrastructure upgrades to ensure their reliable operation, but a new study from Stanford University says most of those upgrades may be unnecessary. Better grid reliability could be achieved instead by installing software in homes and businesses that coordinates various consumer demands and resources. Such coordination not only improves reliability of the electric grid, but also ...

Conditional cash transfer programs have prevented 739,919 child deaths in Latin America

2023-07-14

Over the past two decades, conditional cash transfer programmes have led to a 24% reduction in child mortality in Brazil, Mexico and Ecuador, equivalent to more than 700,000 child deaths averted, according to an impact evaluation study led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by “la Caixa” Foundation. The results, published in JAMA Network Open, also show that expanding these programmes could save more than 150,ooo lives by mitigating the effects of the ...

Neighborhood racial segregation linked to shorter life spans by four years

2023-07-14

New nationwide study is first to examine implications of racial segregation on life expectancy by neighborhood Findings quantify how neighborhood segregation contributes to racial inequities in life expectancy Black residents living in heavily segregated areas experienced higher rates of poverty and unemployment and less education CHICAGO --- Black residents living in highly segregated neighborhoods have significantly shortened life expectancies, reports a new Northwestern Medicine study. Compared to residents living in less segregated predominantly ...

Fintetuning for antibodies

2023-07-14

Antibodies are crucial, not only for treating tumors and infections. Sometimes, however, the immune reaction they trigger can be too strong and end up causing more damage, for example in the case of people infected with Covid-19. Problems such as these can often be avoided by finetuning antibodies, as Prof. Dr. Falk Nimmerjahn from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and two of his colleagues in the Netherlands and in the UK have now reported in the journal Nature Immunology. In his laboratories, the FAU researcher is carrying out research into immunoglobulin ...

Single-end hybrid Rayleigh Brillouin and Raman distributed fibre-optic sensing system

2023-07-14

The real-time monitoring of facilities, particularly large facilities (such as rail transit systems, large bridges, and buildings), can provide information regarding their surrounding environment and allow their health conditions to be assessed, which is essential for establishing the current concept of smart cities based on the Internet of Things. As a precise real-time monitoring technique, distributed fiber-optic sensing (DFOS) systems, which require long-distance simultaneous measurements along a sensing fiber, are in high demand for various industrial applications. However, ...

Why trees outcompete shrubs to shift upward?

2023-07-14

The findings from this study, led by Professor Eryuan Liang (Institute of Tibetan Plateau Research, Chinese Academy of Sciences), were published as a research article in the journal National Science Review. The study also involved researchers from, CREAF, CSIC, Global Ecology Unit CREAF-CSIC-UAB, Instituto Pirenaico de Ecología (IPE-CSIC), Spain and Université du Québec à Chicoutimi, Canada. Climatic warming is altering the structure and function of alpine ecosystems, including shifts of vegetation boundaries. The upward shift of alpine treelines, the uppermost limit of tree growth forming the boundary between montane forest and alpine communities, ...

New fossil flying reptile ‘Elvis’ takes flight

2023-07-14

A new 145-million-year-old pterosaur (extinct flying reptiles that lived alongside the dinosaurs) was named today by a team of British, American and German researchers. The animal was nicknamed ‘Elvis’ when the fossil was first unearthed in Bavaria, Germany because of the giant pompadour-like bony crest on its skull. Now the animal has been given a formal scientific name of Petrodactyle wellnhoferi. The name translates as ‘Wellnhofer’s stone-finger’ honouring legendary German palaeontologist ...

m6A mRNA modification potentiates Th17 functions to inflame autoimmunity

2023-07-14

N6-methyladenosine (m6A) is the most extensive studied RNA modification across various species, and the important effect of m6A modification in immune system has been revealed in distinct contexts, including mRNA metabolism, cell differentiation, proliferation and response to stimulation. Previous studies from Hua-Bing Li group demonstrated that m6A methyltransferase METTL3 control T cells homeostasis and sustain the suppressive function of regulatory T cells (Tregs). However, the role of m6A methyltransferase in other subtype of T cells remains unknown. T helper cells 17 ...

Exercise during dialysis has positive health impact

2023-07-14

Patients who engage in light exercise while undergoing dialysis are physically fitter and are admitted to hospital less frequently than those who do not. These are the findings of a large-scale study conducted by a consortium led by the Technical University of Munich (TUM). The researchers believe that exercise programs should be offered to dialysis patients as standard. Around 558,000 people in the United States have such severely impaired kidney function that they require dialysis several times per week. In Germany, about 80,000 people regularly undergo ...
