At a glance: People who suffer heart attacks and cardiac arrests in the vicinity of major marathons are more likely to die within a month. The bleaker survival odds are linked to delays in transportation to nearby hospitals. The delays are believed to stem from widespread road closures within the radius of the race. The study findings underscore the need for citywide strategies that ensure rapid transport for medical emergencies in the vicinity of major public events.
Wellness coaching, administered in advance, could reduce a surgical patient’s average hospital stay two days, from seven down to five, when compared to a control group.
Exercise enthusiasts often wonder whether it’s better to eat or fast before a workout. A new study is the first of its kind to show the effects of eating versus fasting on gene expression in adipose (fat) tissue in response to exercise. This difference highlights the different roles fat plays in powering and responding to exercise.
A new study suggests it’s the amount of regular exercise people get, not the amount of body fat they have, that may predict just how well they recover from a stroke. The study is published in the April 5, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology.
People with hypertriglyceridemia often are told to change their diet and lose weight. But a high-fat diet isn’t necessarily the cause for everyone with the condition. UCLA researchers have discovered a subset of people with hypertriglyceridemia whose bodies produce autoantibodies — immune-response molecules that attack their own proteins — causing high levels of triglycerides in the blood.
As little as 10 minutes a day of high-intensity physical activity could help some children reduce their risk of developing heart problems and metabolic diseases such as diabetes, according to an international study led by a researcher at Wake Forest Baptist Medical Center.

From the Broad Street Run here in Philadelphia to the Cherry Blossom 10-mile run in Washington, DC, and others across the country and overseas, running season is just around the corner! And for many people, from avid runners to weekend warriors, that means it’s almost time to lace up your shoes and dust off those training plans. But, recent news stories about runners suffering sudden cardiac arrest (SCA) and other heart-related complications mid-race might leave some wondering if there may actually be a risk to running.
While boxes of decadent chocolates treats, celebratory champagne and romantic high-calorie dinners may dance in your mind as a way to celebrate Valentine’s Day, your heart may be pining for something else. With Valentine's Day just around the corner, it is a great time to look at the state of your heart. “Despite recent progress, cardiovascular disease remains the leading cause of death for both men and women in the United States," said Dr. Sheila Sahni, interventional cardiology fellow at the David Geffen School of Medicine at UCLA and UCLA Barbra Streisand Women’s Heart Health Program. “Making heart healthy lifestyle choices and taking control of your cardiovascular risk factors can help prevent or slow the progression of heart disease.” Every day decisions are important to cardiovascular health, she adds, and Valentine’s Day is a good time to give yourself the gift of lifestyle changes that will benefit you through the year. Check out these tips.
There are no more excuses for being out of shape. Researchers at McMaster University have found that short, intense bursts of stair climbing, which can be done virtually anywhere, have major benefits for heart health. The findings negate the two most common excuses of couch potatoes: no time and no access to the gym.

In two recent peer-reviewed papers published by Nutrients and Growth Hormone and IGF-1 Research, Skidmore College exercise scientist Paul Arciero and colleagues report proven benefits of consuming moderate amounts of protein regularly throughout the day (protein-pacing) combined with a multi-dimensional exercise regimen that includes resistance exercise, interval sprint exercise, stretching and endurance exercise.
Running is one of the most popular forms of fitness. Despite numerous health advantages, running injuries are common with incidence rates ranging from 19.4 to 79.3 percent. Foot strike patterns have been a topic of debate with regards to injury risk in runners. Foot strike patterns are typically separated into three categories: rearfoot strike, where the runner’s heel hits the ground first; midfoot strike, where the runner’s foot lands flat; and forefoot strike, where the runner’s ball of the foot lands on the ground first.
Runners who encounter visual and auditory distractions may be more likely to sustain leg injuries, according to research presented this week at the Association of Academic Physiatrists Annual Meeting in Las Vegas.
Quadricep strength and speed of force production (SFP) both affect physical functioning in people with, or at risk for, knee osteoarthritis, according to research presented this week at the Association of Academic Physiatrists Annual Meeting in Las Vegas.
Frequent soccer ball heading is a common and under recognized cause of concussion symptoms, according to a study of amateur players led by Albert Einstein College of Medicine researchers. The findings run counter to earlier soccer studies suggesting concussion injuries mainly result from inadvertent head impacts, such as collisions with other players or a goalpost. The study was published online today in Neurology®, the medical journal of the American Academy of Neurology.
