High cardiorespiratory fitness is associated with better cognitive performance and lower risk of dementia long term, including in people with a genetic predisposition to dementia, show the findings of a study published online in the British Journal of Sports Medicine.   Cardiorespiratory fitness (CRF) is the capacity of the circulatory and respiratory systems to supply oxygen to muscles and declines increasingly with age as skeletal muscle is lost. CRF declines by around  3% to 6% per decade when people are in their 20s and 30s, but this accelerates to more than 20% per decade by the time people reach their 70s. Low CRF is a strong predictor of cardiovascular ...

The number and type of microbes present in the saliva of pregnant women differ according to whether they are experiencing life stress and symptoms of anxiety, depression and post-traumatic stress disorder (PTSD), finds a study published in the open access journal BMJ Mental Health. Although several studies have shown links between the diversity of microbes in the gastrointestinal tract and stress, anxiety and depression in pregnant women and new mothers, no previous study has looked at the association between the type and number of microorganisms in the mouth and throat—oral microbiome—and ...

PHOENIX, November 19, 2024 — The American Heart Association and the Arizona Cardinals gathered representatives from 12 local schools for cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) training on Nov. 18 at Pima Elementary School in Scottsdale. According to American Heart Association data, Nearly 9 out of 10 people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of the time. CPR, especially if performed immediately, can double or triple a person’s chance of survival. “Early ...

As rates of obesity, as defined by body mass index (BMI), continue to climb in the United States, so have efforts to lose weight, including a new era of weight-loss drugs. Yet a new systematic review and meta-analysis published today in the British Journal of Sports Medicine found that cardiorespiratory fitness was a stronger predictor of both cardiovascular disease and all-cause mortality than BMI. The researchers found that fit individuals across all BMI categories had statistically similar risks of death from all causes or cardiovascular disease. By contrast, unfit individuals ...

  LA JOLLA, CA—In most people, the lung-infecting pathogens known as respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) trigger mild cold-like symptoms. But in infants and seniors, these viruses can cause severe pneumonia and even death. Vaccines against both viruses, however, have been difficult to design. Now, Scripps Research scientists have analyzed the structure and stability of a critical RSV and hMPV protein to better design vaccines that target it. Their research, ...
