Potassium supplementation and prevention of atrial fibrillation after cardiac surgery

JAMA

2024-08-31

(Press-News.org) About The Study: For atrial fibrillation after cardiac surgery prophylaxis, supplementation only when serum potassium concentration fell below 3.6 mEq/L was noninferior to the current widespread practice of supplementing potassium to maintain a serum potassium concentration greater than or equal to 4.5 mEq/L. The lower threshold of supplementation was not associated with any increase in dysrhythmias or adverse clinical outcomes.

Low-dose triple-pill vs standard-care protocols for hypertension treatment in Nigeria

2024-08-31

About The Study: Among Black African adults with uncontrolled hypertension, a low-dose triple-pill protocol achieved better blood pressure lowering and control with good tolerability compared with the standard-care protocol.

Single blood test predicts 30-year cardiovascular disease risks for women

2024-08-31

Research supported by the National Institutes of Health has found that measuring two types of fat in the bloodstream along with C-reactive protein (CRP), a marker of inflammation, can predict a woman’s risk for cardiovascular disease decades later. These findings, presented as late-breaking research at the European Society of Cardiology Congress 2024, were published in the New England Journal of Medicine. “We can’t treat what we don’t measure, and we hope these findings move the field closer to identifying even earlier ways to detect and prevent heart disease,” ...

Blood test of three factors predicts 30-year risk of heart attack, stroke and cardiovascular death in American women

2024-08-31

KEY TAKEAWAYS Brigham researchers assessed data from more than 27,000 participants in the Women’s Health Study who were followed for 30 years. An initial, one-time measure of three biological markers—hsCRP, LDL-cholesterol and lipoprotein(a)—in their blood predicted their risk of major cardiovascular events over the following decades. The findings support universal screening for inflammation and lipoprotein(a) in addition to cholesterol, as well as earlier, aggressive use of targeted interventions, particularly among women for whom cardiovascular disease remains ...

Digital consultations improve the rate at which patients receive optimal medication

2024-08-31

Patients with heart failure, a condition affecting more than 60 million worldwide, are four times more likely to receive the optimal combination of medications after 12 weeks of digital consultations. Researchers from five Dutch hospitals, coordinated by Amsterdam UMC, found that the use of digital consults improved care while maintaining patient satisfaction. These results are published today in Nature Medicine and simultaneously presented at the annual conference of the European Society of Cardiology. "During the COVID-pandemic almost all of our patients were suddenly digital consult patients and, to be honest, this worked well but there were also ...

Exclusive chemical recycling of PET from cloth waste and plastic waste mixtures

2024-08-31

Tokyo, Japan – A research team led by Professor Kotohiro Nomura from Tokyo Metropolitan University has developed a method for the depolymerization of PET (polyethylene terephthalate) using alcohols and an inexpensive, readily available iron trichloride catalyst. This method can be applied to the selective chemical recycling of both textile and plastic waste mixtures. Plastic waste is a significant environmental issue that requires urgent attention. However, the rate of plastic reuse (material recycling) remains low, particularly in the case of chemical recycling into raw materials, a process known as chemical recycling. Polyesters, which ...

New species of Antarctic dragonfish highlights its threatened ecosystem

2024-08-30

A new species of Antarctic dragonfish, Akarotaxis gouldae or Banded Dragonfish, has been discovered in waters off the western Antarctic Peninsula by researchers at William & Mary’s Virginia Institute of Marine Science (VIMS). The species, named in honor of the recently decommissioned Antarctic research and supply vessel (ARSV) Laurence M. Gould and its crew, exemplifies both the unknown biodiversity and fragile state of the Antarctic ecosystem. Described in the journal Zootaxa, Akarotaxis gouldae was initially identified through genetic analysis. Larval specimens collected off the coast of Antarctica while trawling for zooplankton ...

COVID-19 vaccination mandates boosted uptake among health care workers

2024-08-30

At the peak of the COVID-19 pandemic in 2021, governments and health care centers across the country faced a difficult but important question: Should health care workers be required to obtain the COVID-19 vaccine? It was an economic quandary as much as an ethical one. Vaccine mandates could cause reductions in staff, either from workers missing time due to recovery from the vaccine or from opting to seek employment elsewhere. Additionally, health care workers are highly educated on the value of vaccines and had seen ...

New UMass study identifies factors that predict physical activity for nursing students

2024-08-30

AMHERST, Mass. -- New research from the Mechanical and Industrial Engineering Department at the University of Massachusetts Amherst, in collaboration with the Elaine Marieb Center for Nursing and Engineering Innovation, is helping to identify barriers to physical activity in nurses. Published in PLOS ONE, the study reports that the key factors influencing exercise include intrinsic motivation, certain types of social support, certain demographic identifiers and the use of health-tracking technology. Nursing is a notoriously exhausting career, marked by irregular and long shifts and high physical demands. At the same time, prior studies show that about half ...

Auburn University secures two NSF grants to transform physics education

2024-08-30

Auburn University’s Department of Physics has been awarded two significant National Science Foundation (NSF) grants, marking a major step toward transforming physics education across all levels—from introductory courses to graduate studies. The grants, led by Assistant Professor Eric Burkholder, a specialist in Physics Education Research, aim to close the gap between traditional physics instruction and the complex problem-solving skills needed for real-world scientific challenges. The cornerstone of these projects is the recognition that traditional methods of teaching physics—while ...

How hope beats mindfulness when times are tough

2024-08-30

A recent study finds that hope appears to be more beneficial than mindfulness at helping people manage stress and stay professionally engaged during periods of prolonged stress at work. The study underscores the importance of looking ahead, rather than living “in the moment,” during hard times. Mindfulness refers to the ability of an individual to focus attention on the present, in a way that is open, curious and not judgmental. Essentially, the ability to be fully in the moment. “There’s a lot of discussion ...
