Accelerometer-derived ‘weekend warrior’ physical activity and incident cardiovascular disease

JAMA

2023-07-18

(Press-News.org) About The Study: In an analysis of 89,000 individuals providing a week of accelerometer-based physical activity data, a weekend warrior pattern of physical activity (i.e., most moderate to vigorous physical activity achieved over 1-2 days) was associated with similarly lower risks of incident atrial fibrillation, heart attack, heart failure, and stroke compared with more evenly distributed physical activity.

Authors: Patrick T. Ellinor, M.D., Ph.D., of Massachusetts General Hospital in Boston, is the corresponding author.

Sleep architecture, obstructive sleep apnea, and cognitive function in adults

2023-07-18

About The Study: This study found that better sleep consolidation and the absence of obstructive sleep apnea were associated with better global cognition over five years of follow-up. These findings suggest that the role of interventions to improve sleep for maintaining cognitive function requires investigation. Authors: Matthew P. Pase, Ph.D., of Monash University in Melbourne, Australia, is the corresponding author. To access the embargoed study: Visit our For The Media website at ...

Prenatal health care outcomes before, during pandemic

2023-07-18

About The Study: The findings of this study of 151,000 pregnant individuals suggest that a multimodal prenatal health care model combining in-office and telemedicine visits performed adequately compared with in-office only prenatal health care, supporting its continued use after the pandemic.

USPSTF recommendation statement on screening for lipid disorders in children and adolescents

2023-07-18

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger. Familial hypercholesterolemia and multifactorial dyslipidemia are two conditions that cause abnormally high lipid levels in children, which can lead to premature cardiovascular events (e.g., heart attack and stroke) and death in adulthood. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this recommendation statement is consistent with its 2016 recommendation.

Mass General researchers find “weekend warrior” physical activity provides similar heart-related benefits as more regular exercise

2023-07-18

BOSTON – People who find it difficult to find time to exercise during a busy work week may concentrate their moderate-to-vigorous physical activity to one to two days of the week or weekend. In a recent analysis published in JAMA that was conducted by investigators at Massachusetts General Hospital (MGH), this “weekend warrior” pattern was associated with similarly lower risks of heart disease and stroke compared with more evenly distributed exercise. Guidelines recommend at least 150 minutes of moderate-to-vigorous physical activity per week for overall health, but it’s unclear if concentrated ...

First BepiColombo flyby of Mercury finds electron rain triggers X-ray auroras

2023-07-18

BepiColombo, the joint European Space Agency (ESA) and Japanese Aerospace Exploration Agency (JAXA) mission, has revealed how electrons raining down onto the surface of Mercury can trigger high-energy auroras. The mission, which has been enroute to the Solar System’s innermost planet since 2018, successfully carried out its first Mercury flyby on 1 October 2021. An international team of researchers analysed data from three of BepiColombo’s instruments during the encounter. The outcomes of this study have been published today in the scientific ...

PCORI approves $208 million for research on heart disease, chronic disease, palliative care and a range of conditions impacting people of all ages

2023-07-18

July 18, 2023 WASHINGTON, DC – The Patient-Centered Outcomes Research Institute (PCORI) today announced funding awards totaling $208 million to support 17 new comparative clinical effectiveness research (CER) studies, including four trials of particularly large scale and scope tackling complex questions. All the approved studies aim to fill evidence gaps and enhance health care decision making with a focus on a variety of high-burden concerns. In addition, PCORI awarded $2 million for a project intended to accelerate the adoption of strategies ...

Scientists unravel evolutionary history of the Arctic flora

2023-07-18

A team led by Prof. WANG Wei from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has unraveled the evolutionary history of the Arctic flora. The study was published in Nature Communications. The Arctic tundra, to the north of the natural tree line, is a relatively young and new type of biome and is particularly sensitive to the effects of global warming. The composition, density, and distribution of Arctic vegetation have been changing as a result of climate warming. Therefore, there is an urgent need to better understand how the Arctic flora has been shaped over time. In this study, the researchers selected 32 angiosperm clades comprising ...

Aggregation-induced catalysis: Asymmetric catalysis with chiral aggregates

2023-07-18

Asymmetric synthesis and catalysis have been actively pursued in chemical and materials sciences. Increasing numbers of drugs and pesticides contain chiral structural units in their structures since drug actions require conformational matching to increase their potency and selectivity toward receptors and other active targets inside and on the surfaces of cells. Structural design of pharmaceuticals plays key role in reducing or avoiding severe side effects during their action processes. In the meanwhile, more advanced materials, ...

New research addresses mental health crisis in the construction industry

2023-07-18

New research is tackling the mental health crisis in the construction industry – highlighting the benefits of an on-site Health Hub on worker wellbeing. The construction industry has the highest number of deaths by suicide compared to other employment sectors, accounting for 20% of all suicides by occupation between 2011-2019 (ONS). Now, in a joint collaboration between the University of Warwick and National Grid, researchers are attempting to address this problem. A Health Hub was set up on a construction site in Sellindge, Kent which employees could use during their long working days. The Health Hub, a pilot for future projects which could be implemented ...

Study highlights urgent need to protect world’s forests from non-native pests in the face of climate change
