Genetic predisposition to excess body weight and survival in women diagnosed with breast cancer

JAMA Network Open

2026-01-13

(Press-News.org) About The Study: In this cohort of nonmetastatic breast cancer survivors, women who were genetically predisposed to having a higher body mass index were at increased risk of all-cause mortality. Targeted lifestyle recommendations to mitigate their genetic predisposition should be considered to lower this risk.

New mechanism links Epstein-Barr virus to MS

2026-01-13

The immune system’s reaction to the common Epstein-Barr virus can ultimately damage the brain and contribute to multiple sclerosis (MS). This is shown by new research from Karolinska Institutet, published in Cell. The study provides new insight into the long-suspected link between Epstein-Barr virus (EBV) and MS. Multiple sclerosis is a chronic inflammatory disease in which the immune system attacks the central nervous system and causes nerve damage. It has long been known that everyone who develops MS has had an infection with the Epstein-Barr virus (EBV) – a common virus that often infects young people, sometimes causing glandular fever but ...

Genetic risk factor and viral infection jointly contribute to MS

2026-01-13

One of the leading triggers for multiple sclerosis (MS) is an infection with the Epstein-Barr virus. However, certain gene variants also play an important role. Researchers at the University of Zurich have now shown that it is the molecular interaction between environmental and genetic risk factors that ultimately triggers the disease. Recent findings suggest that the Epstein-Barr virus (EBV) is involved in both causing multiple sclerosis (MS) and shaping its progression. Everyone who has MS has previously ...

When a virus releases the immune brake: New evidence on the onset of multiple sclerosis

2026-01-13

Autoimmune diseases such as multiple sclerosis arise when the immune system turns against the body itself. Yet for most of them, it remains unclear why this process begins. Researchers have now identified how the Epstein-Barr virus can, under specific conditions, initiate early multiple sclerosis-like damage in the brain. This offers a new perspective on how rare immune events may shape disease risk. There is mounting evidence that the Epstein-Barr virus may play a part in causing autoimmune diseases like multiple sclerosis. But one puzzle remains: almost everyone gets this virus early in life, yet only ...

Wyss Institute-led collaboration awarded by ARPA-H PRINT program to engineer off-the-shelf, universal, transplant-ready graft for liver failure

2026-01-13

(BOSTON) — The majority of human illnesses is caused by damage of a single organ like the liver whose failure accounts for 2M deaths worldwide every year. Orthotopic transplants are the only curative therapy available, but the severe shortage of donor organs, which are reserved for the most severe cases, leaves millions of patients without an accessible solution. The liver is the central hub in our body for filtering blood, metabolizing nutrients and toxins, producing essential proteins and bile, storing vitamins and glucose, and a multitude of other processes. Accordingly, an excessive loss of liver function through various diseases poses ...

Research on the behavioral mechanisms of rural distributed photovoltaic development: A view of prosumer perspective

2026-01-13

As global energy transitions accelerate, distributed PV systems have become a cornerstone of rural energy transformation in China, shifting rural households from passive energy consumers to active prosumers. However, low household electricity demand, limited grid capacity, and complex stakeholder interactions hinder widespread adoption. To address these challenges, researchers Wenbing Zhou and Songlin Tang from the School of Economics at Shandong Technology and Business University developed a multi-agent dynamic game model. The model incorporates four core stakeholders: village organizations, PV enterprises, grid companies, and rural households, analyzing their ...

More surgical patients are on opioid use disorder medications — hospitals must modernize pain care

2026-01-13

More Surgical Patients Are on Opioid Use Disorder Medications — Hospitals Must Modernize Pain Care CHICAGO – As more Americans receive treatment for opioid use disorder, that progress is increasingly showing up in the operating room, creating an urgent need to modernize how pain is managed during and after major surgery, according to a study in the February 2026 issue of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA). The study documents a steady rise in surgical patients using medications for opioid use disorder (MOUD), highlighting a gap between current surgical pain practices and the needs of today’s patients. "From ...

New study reveals strategic logic behind global patent litigation venue selection

2026-01-13

A new study published in the Strategic Management Journal sheds light on how multinational firms make strategic decisions about where to pursue patent litigation in an increasingly interconnected and politically complex global environment. Rather than treating patent disputes as isolated, country-by-country legal actions, the research shows that firms approach litigation as part of a coordinated global strategy. Drawing on patent litigation data from leading technology firms across 50 countries over ...

An abnormally slow heart rate is associated with xylazine-fentanyl overdose; primarily seen in northeastern United States

2026-01-13

Researchers have identified bradycardia—an abnormally low heart rate–as a symptom of xylazine-opioid overdose. This breakthrough finding from the Icahn School of Medicine at Mount Sinai may help emergency medicine physicians detect whether patients have been exposed to xylazine, a drug that is increasingly found as an additive to the illicit fentanyl supply, particularly in the Northeast. Accurate detection of xylazine overdose could help physicians take the correct steps to save lives ...

The path to solar weather forecasts

2026-01-13

At times the sun ejects energetic material into space which can have consequences for space-based and even ground-based electronic technology. Researchers aim to understand this phenomenon and find ways to forecast it, including how ejected material evolves as it travels through the solar system. For the first time, researchers, including those from the University of Tokyo, made high-quality measurements of an evolving cloud of solar ejecta by using multiple space-based instruments which were not designed to do so, and observed the way the ...

Inflammation and mitochondrial dysfunction in cirrhotic cardiomyopathy: therapeutic implications

2026-01-13

Background and Aims Cirrhotic cardiomyopathy (CCM) is a significant complication of cirrhosis, but its progression and underlying mechanisms remain incompletely understood. This study aimed to investigate dynamic changes in cardiac function, pathology, inflammation, and mitochondrial damage in a mouse model of CCM, and to compare echocardiographic characteristics in patients with cirrhosis. Methods Bile duct ligation was performed in male C57BL/6J mice to induce cirrhosis. Longitudinal analyses were conducted over eight weeks. Cardiac function was assessed using serum biomarkers, echocardiography, and electrocardiography. Pathology was examined with hematoxylin and eosin, ...
