Widening gender gap in life expectancy in the US

JAMA Internal Medicine

2023-11-13

(Press-News.org) About The Study: This analysis finds that COVID-19 and the drug overdose epidemic were major contributors to the widening gender gap in life expectancy (nearly six years) between women and men in recent years. Men experienced higher COVID-19 death rates for likely multifactorial reasons, including higher burden of comorbidities and differences in health behaviors and socioeconomic factors, such as labor force participation, incarceration, and homelessness. Differentially worsening mortality from diabetes, heart disease, homicide, and suicide suggest that chronic metabolic disease and mental illness may also contribute.

Shift from smoking cigarettes to vaping nicotine in young adults

2023-11-13

About The Study: The data from this nationally representative survey study reveal a shift in tobacco use among young adults (ages 18-24), showing historically low cigarette use, which has positive public health significance. However, e-cigarette use is higher (14.5%) than reported previously, coinciding with the introduction of salt-based devices in 2015 to 2018. Over half of established vaping young adults never regularly smoked. Research suggests that exclusive e-cigarette users are unlikely to ...

Trends in prevalence of breastfeeding initiation and duration among US children

2023-11-13

About The Study: The findings of this study indicate an increase in the prevalence of breastfeeding initiation and breastfeeding duration at 12 months from 1999 to 2018 in the U.S. Temporal changes of breastfeeding duration at 12 months were more prevalent among male infants, older mothers, Mexican American and multiracial participants, and households with higher income. Authors: Yongjun Zhang, Ph.D., M.D., of the Shanghai Jiao Tong University School of Medicine in Shanghai, is the corresponding author. To access ...

Study finds melatonin use soaring among youth

2023-11-13

Nearly one in five school-aged children and preteens now take melatonin for sleep, and some parents routinely give the hormone to preschoolers, according to new research from the University of Colorado Boulder published Nov. 13 in JAMA Pediatrics. This concerns the authors, who note that safety and efficacy data surrounding the products are slim, such dietary supplements lack full regulation by the Food and Drug Administration. “We hope this paper raises awareness for parents and clinicians, and sounds the alarm for the scientific community,” said lead author Lauren Hartstein, PhD, a postdoctoral fellow ...

How good can overpower evil in the genetic determination of Alzheimer’s disease

2023-11-13

San Francisco—November 13, 2023—Researchers at Gladstone Institutes have discovered that a rare genetic variant known as the “Christchurch mutation” can block detrimental effects of apolipoprotein E4, the best-established risk factor for the most common form of Alzheimer’s disease. The apolipoprotein E (APOE) gene has long been known to affect the risk of Alzheimer’s disease through its three main variants: E2 (low risk), E3 (intermediate risk), and E4 (high risk). More recently, a ...

Recreation of ancient seawater reveals which nutrients shaped the evolution of early life

2023-11-13

Scientists know very little about conditions in the ocean when life first evolved, but new research published in Nature Geoscience has revealed how geological processes controlled which nutrients were available to fuel their development. All life uses nutrients such as zinc and copper to form proteins. The oldest lifeforms evolved in the Archean Eon, three and a half billion years before the dinosaurs first appeared. These microbes showed a preference for metals such as molybdenum and manganese compared to their more recent counterparts. This ...

Cycle of fasting and feeding is crucial for healthy ageing

2023-11-13

Fasting interventions, which involve alternating periods of fasting and refeeding, are generally thought to improve health. But these interventions don’t work as well in old animals. The question is: Why? By studying the short-lived killifish, researchers at the Max Planck Institute for Biology of Ageing in Cologne have shown that older fish deviate from a youthful fasting and refeeding cycle, and instead enter a state of perpetual fasting, even when ingesting food. However, the benefits of refeeding after fasting in old killifish can be restored by genetically activating a specific subunit of AMP kinase, an important sensor ...

How climate change could be affecting your brain

2023-11-13

A new element of the catastrophic impacts of climate change is emerging – how global warming is impacting the human brain. In a paper published today in Nature Climate Change, an international team of academics explore the ways in which research has shown that a changing environment affects how our brains work, and how climate change could impact our brain function in the future. The paper is led by the University of Vienna with input from the universities of Geneva, New York, Chicago, Washington, Stanford, Exeter in the UK and the Max Plank Institute in Berlin. It also explores the role that neuroscientists can play in further understanding and addressing ...

Reducing systolic blood pressure to less than 120 mm Hg reduced cardiovascular event risk

2023-11-13

Research Highlights: In a 3-year trial, intensive treatment with antihypertensive medication to reduce systolic blood pressure, the top number, to less than 120 mm Hg reduced cardiovascular disease events among people at high-risk for cardiovascular disease by 12% compared to standard treatment with a target of less than 140 mm Hg. The effects were consistent regardless of participants’ diabetes status (Type 1, Type 2 or none) or history of stroke. Embargoed until 8 a.m. ET, Monday, Nov. 13, 2023 PHILADELPHIA, ...

Ovarian cancer: Artificial intelligence predicts therapy responses

2023-11-13

A model based on artificial intelligence is able to predict the therapy outcome (measured by volumetric reduction of tumor lesions) in 80% of ovarian cancer patients. The AI-based model has an accuracy of 80%, significantly better than current clinical methods. The tool, named IRON (Integrated Radiogenomics for Ovarian Neoadjuvant therapy), analyzes various patient clinical features, from circulating tumor DNA in the blood (liquid biopsy) to general characteristics (age, health status, etc.), tumor markers, and disease images obtained through CT scans. ...

American Heart Association honors Gladstone President Deepak Srivastava with Distinguished Scientist Award
