The 33 million people with atrial fibrillation worldwide not only suffer from bothersome symptoms, but also face a fivefold increased risk of stroke and a twofold increased risk of death. Research teams led by Mayo Clinic published three connected studies on Friday, March 15, clarifying the benefits of catheter ablation versus rate- or rhythm-control medications to treat atrial fibrillation.

Atrial fibrillation is a common arrhythmia that affects an estimated 30 million people worldwide. New research shows that catheter ablation, a common cardiovascular procedure, appears no more effective than drug therapy to prevent strokes, deaths and other complications in patients with atrial fibrillation. But patients who receive catheter ablation experience much greater symptom relief and long-term improvements in quality of life.

Less than 10 percent of the treatment recommendations US doctors rely on to manage care for heart patients are based on evidence gained from multiple large, randomized clinical trials -- the gold standard for obtaining scientific data.

In a survey of Catholic hospitals throughout the country, researchers at the University of Colorado Anschutz Medical Campus found many did not advertise their religious affiliation and the majority did not explain how that affiliation results in health care restrictions.

Eggs are a source of dietary cholesterol. This observational study pooled data from six study groups for more than 29,000 people to determine the associations of consuming dietary cholesterol or eating eggs with risk of cardiovascular disease (CVD) and death.

Some patients seek care at Catholic hospitals but others may not because aspects of reproductive and end-of-life care can be limited by ethical and religious directives for Catholic hospitals based on the church's moral teachings. This research letter analyzed the websites of 646 hospitals listed in the Catholic Health Care Directory to see whether the hospitals described their religious identity and associated health care practices.

Light physical activity such as gardening, strolling through a park, and folding clothes might be enough to significantly lower the risk of cardiovascular disease among women 63 and older, a new study has found. This kind of activity, researchers said, appears to reduce the risk of cardiovascular disease events such as stroke or heart failure by up to 22 percent, and the risk of heart attack or coronary death, by as much as 42 percent.

Catheter ablation, a common cardiovascular procedure, appears no more effective than drug therapies in preventing strokes, deaths, and other complications in patients with atrial fibrillation. However, patients who get the procedure experience much greater symptom relief and long-term improvements in the quality of life, including fewer recurrences of the condition and fewer hospitalizations, than those who get only drugs.

A new system for synthesizing quantum dots across the entire spectrum of visible light drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control.

An international team of researchers presents a comprehensive and renewed focus on the common, yet poorly understood condition of bacterial vaginosis (BV) and how the microbial make-up of the vagina can affect a woman's risk of acquiring HIV and AIDS.

Dysregulation of the signaling pathway known as the beta-catenin-dependent Wnt can also cause embryo malformation and contribute for the development of breast and cervical cancer.

After the war is over, veterans face a new threat. They are more likely to have heart disease at a younger age than nonveterans, and this could herald a new health crisis on the horizon.

Pennsylvania Auditor General Eugene DePasquale kicked off his first of three public hearings on climate change at Penn State on Thursday, March 14, 2019. His office is compiling a special report to mitigate the effects of climate change in Pa. … Click to Continue »

(Kazan Federal University) The subject of the prize, spectral noise logging, is a popular topic of research for many petroleum engineering centers. In particular, Russia has several of those.

(European Society for Blood and Marrow Transplantation) This Patient, Family and Donor Day session will include clinical experts on a range of post-transplant issues. The patient advocates session will include international speakers focusing on issues relevant to organizations who advocate on behalf of transplant patients.

(Siberian Federal University) A group of researchers is in the process of developing a highly sensitive biosensor designed to detect toxic substances using bioluminescent inhibitory analysis as well as to monitor a biomarker for indicating stress and cancer, namely heat shock proteins 90 (Hsp90).

(Cirad) Senegal and Ethiopia are implementing an ambitious project aimed at increasing the presence of micronutrients in basic foodstuffs, through the use of agro-ecological practices in the field. The idea is to thereby contribute to addressing problems of malnutrition that affect mothers and their children. This experiment, coordinated by CIRAD, will be conducted until 2021 and could eventually benefit other countries in the Sahel.

Many countries today face the difficulties of teaching kids of religious and ethnic minorities. Schools are especially important in general adaptation processes.

The new study found that 40% of large-scale randomised controlled trials (RCTs) in the UK and the US failed to produce any evidence as to whether an educational intervention helped to boost academic attainment or not.

Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy.

An international study co-led by researchers from the Spanish National Research Council (CSIC) at the Institute of Evolutionary Biology (IBE) and Harvard University (USA) has developed a genetic map of the Iberian Peninsula covering the last 8,000 years.

Researchers from the University of Copenhagen have discovered autoreactive cells in persons suffering from narcolepsy. This is a new, important proof that the sleep disorder is an autoimmune disease. This knowledge may lead to better treatment of the chronic condition, the researchers behind the new discovery believe.

Scientists at the Max Planck Institute for Chemical Ecology have discovered that repellent odors suppress the perception of pleasant smells. This happens because certain brain structures that respond to attractive odors are inhibited by a repellent one. These processes in the brain are also reflected in the behavior of the flies. This helps them to avoid spoiled or infected food sources, which would have fatal consequences for the flies and their offspring.
