Assessment of hospital-onset SARS-CoV-2 infection rates and testing practices

JAMA Network Open

2023-08-28

(Press-News.org) About The Study: In this study of hospitals reporting SARS-CoV-2 infections, there was an increase of hospital-onset SARS-CoV-2 infections when community-onset infections were higher, indicating a need for ongoing and enhanced surveillance and prevention efforts to reduce in-hospital transmission of SARS-CoV-2 infections, particularly when community-incidence of SARS-CoV-2 infections is high.

Trends in suicide rates among post-9/11 veterans with and without traumatic brain injury

2023-08-28

About The Study: In a large cohort of U.S. military veterans serving after 9/11, suicide rates increased more than 10-fold from 2006-2020, a significantly greater rate of change than in the U.S. adult population. Over the 15-year period, veterans with traumatic brain injury (TBI) had suicide rates 56% higher than veterans without TBI and three times higher than the U.S. adult population. Authors: Jeffrey T. Howard, Ph.D., of the University of Texas at San Antonio, is the corresponding author.

Estimated lifetime gained with cancer screening tests

2023-08-28

About The Study: The findings of this systematic review and meta-analysis of 18 long-term randomized clinical trials involving 2.1 million individuals suggest that current evidence does not substantiate the claim that common cancer screening tests save lives by extending lifetime, except possibly for colorectal cancer screening with sigmoidoscopy. Authors: Michael Bretthauer, M.D., Ph.D., of the University of Oslo in Oslo, Norway, is the corresponding author.

Neuropathologic and clinical findings in young contact sport athletes exposed to repetitive head impacts

2023-08-28

About The Study: This case series found that young brain donors exposed to repetitive head impacts were highly symptomatic regardless of chronic traumatic encephalopathy (CTE) status, and the causes of symptoms in this sample are likely multifactorial. Future studies that include young brain donors unexposed to repetitive head impacts are needed to clarify the association among exposure, white matter and microvascular pathologic findings, CTE, and clinical symptoms. Authors: Ann C. McKee, M.D., of the U.S. Department of Veteran Affairs in Boston, is the corresponding author. To access the embargoed study: Visit our For The Media website ...

Due to sea-ice retreat, zooplankton could remain in the deep longer

2023-08-28

Due to intensifying sea-ice melting in the Arctic, sunlight is now penetrating deeper and deeper into the ocean. Since marine zooplankton respond to the available light, this is also changing their behaviour – especially how the tiny organisms rise and fall within the water column. As an international team of researchers led by the Alfred Wegener Institute has now shown, in the future this could lead to more frequent food shortages for the zooplankton, and to negative effects for larger species including seals and whales. The study ...

Hypoxia and panvascular diseases: exploring the role of hypoxia-inducible factors in vascular smooth muscle cells under panvascular pathologies

2023-08-28

This study is led by Prof. Junbo Ge (Department of Cardiology, Zhongshan Hospital, Fudan University, Shanghai Institute of Cardiovascular Diseases), Prof. Hua Li (Department of Cardiology, Zhongshan Hospital, Fudan University, Shanghai Institute of Cardiovascular Diseases), and Prof. Hao Lu (Department of Cardiology, Zhongshan Hospital, Fudan University, Shanghai Institute of Cardiovascular Diseases). As an emerging concept, panvascular diseases encompass a group of cardiovascular disorders characterized mainly by atherosclerosis, involving crucial organs such as the ...

Spintronics: X-ray microscopy unravels the nature of domain walls

2023-08-28

Magnetic skyrmions are tiny vortices-like of magnetic spin textures that - in principle - can be used for spintronic devices, for example very fast and energy-efficient data storage devices. But at the moment it is still difficult to control and manipulate skyrmions at room temperature. A new study at BESSY II analyses the formation of skyrmions in ferrimagnetic thin films of dysprosium and cobalt in real time and with high spatial resolution. This is an important step towards characterising suitable materials with skyrmions more precisely in the future. Isolated magnetic skyrmions are topologically protected spin textures that are in the focus of research ...

World first drug to target form of previously untreatable life-threatening ‘bad cholesterol’

2023-08-28

A new drug offers a breakthrough world first treatment for Lipoprotein(a), a largely genetic form of cholesterol that increases the risk of heart attack and stroke, announced today by study lead Professor Stephen Nicholls, Director of the Monash University’s Victorian Heart Institute and Victorian Heart Hospital. High levels of Lipoprotein(a), known as Lp(a) or spoken as ‘LP little a’, impact one in five people globally with no approved treatment currently on the market. The trial demonstrated the success of Muvalaplin - the first oral drug ever ...

An all-in-one surface design of copper nanowire assemblies to achieve ~100% defrosting efficiency

2023-08-28

Scientists at Dalian University of Technology propose a design of copper nanowire assemblies that can sufficiently enhance the de-icing and defrosting efficiency without conventional energy input. Specifically, the defrosting efficacy approaches 100%, a record-high value compared to reported studies. The research, published in International Journal of Extreme Manufacturing, shows a simple electrochemical method for fabricating nanowire assemblies with controlled pattern, hierarchy, and size. This enables the simultaneous presentation of photothermal, thermal conductive, and superhydrophobic ...

Social justice for traditional knowledge holders will help conserve Europe’s nature

2023-08-28

It is well known that biodiversity of cultural landscapes is threatened by land abandonment and agricultural intensification. Traditional, low chemical and machinery input management systems have long been acknowledged for their diverse benefits to maintain and enhance biodiversity, however, the recognition of traditional knowledge, on which these traditional management practices are based, started only relatively recently. The recognition of traditional knowledge holders themselves is an even more recent phenomenon. A recently published paper aims to ...

Trial re-evaluates routine defibrillator implantation after myocardial infarction

2023-08-28

Amsterdam, Netherlands – 26 Aug 2023: Is the routine implantation of an implantable cardioverter defibrillator (ICD) in myocardial infarction survivors with heart failure still an adequate therapy for prevention of sudden cardiac death? The PROFID EHRA trial is set to answer this question in a large, multicentre, EU-funded study set to enrol the first patient this summer. The consortium of partners and colleagues involved in the trial, including the European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC), will meet during ESC Congress 2023 to discuss the start of the study. Myocardial ...
