High Heart Rate At Rest Signals Higher Risk Of Death Even In Fit Healthy People
Date: Apr-16-2013A high heart rate (pulse) at rest is linked to a higher risk of death even in physically fit, healthy people, suggests research published online in the journal Heart. A resting heart rate - the number of heart beats per minute - is determined by an individual's level of physical fitness, circulating hormones, and the autonomic nervous system. A rate at rest of between 60 and 100 beats per minute is considered normal...
Men With Enlarged Prostate Get Symptom Relief From Minimally-Invasive Shrinking Treatment
Date: Apr-16-2013Enlarged prostate, or benign prostatic hyperplasia (BPH), affects most men after middle age, causing frequent nighttime trips to the bathroom and health problems. Now early findings from a small US study presented at a conference this week suggests a minimally-invasive treatment called prostatic artery embolization (PAE), which shrinks the prostate back to its more youthful size by reducing blood flow to it, may provide significant relief from symptoms and help men avoid surgery...
Revealing The Secrets Of Bacterial Slime
Date: Apr-16-2013Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics. When under threat, some bacteria can shield themselves in a slimy protective layer, known as a biofilm. It is made up of communities of bacteria held together to protect themselves from attack. Biofilms cause dental plaque and sinusitis; in healthcare, biofilms can lead to life threatening and difficult to treat infections, particularly on medical implants such as catheters, heart valves, artificial hips and even breast implants...
In Patients Needing Gastric Tubes, Additional Imaging Gives Better View And Reduces Complications
Date: Apr-16-2013Additional fluoroscopic and CT views can substantially reduce complications that occur during percutaneous radiologic gastrostomy, a procedure used for patients who require a gastric tube for nutritional support. "In a study of 146 patients, we saw a major complications rate of 5.9%," said Dr. Erich Lang, of SUNY Downstate Medical Center, in Brooklyn, NY and lead author of the study. Major complications included organ injury with hemorrhage and colonic perforation, he said. Minor complications, such as tube leakage or dislodgement, occurred in 17.6% of patients, he said...
Patient Outcomes Significantly Improved By L-Carnitine Following Heart Attack
Date: Apr-16-2013L-carnitine significantly improves cardiac health in patients after a heart attack, say a multicenter team of investigators in a study published in Mayo Clinic Proceedings. Their findings, based on analysis of key controlled trials, associate L-carnitine with significant reduction in death from all causes and a highly significant reduction in ventricular arrhythmias and anginal attacks following a heart attack, compared with placebo or control. Heart disease is the leading cause of death in the United States...
New Research Highlights Opportunities For Smoking Intervention Programs
Date: Apr-16-2013The company you keep in junior high school may have more influence on your smoking behavior than your high school friends, according to newly published research from the University of Southern California (USC). The study, which appears in the Journal of Adolescent Health, identifies how friends' and parental influence on cigarette smoking changes from junior high to high school...
"Complexity By Subtraction" A Possible Alternative Explanation For Life's Complexity
Date: Apr-16-2013Evolution skeptics argue that some biological structures, like the brain or the eye, are simply too complex for natural selection to explain. Biologists have proposed various ways that so-called 'irreducibly complex' structures could emerge incrementally over time, bit by bit. But a new study proposes an alternative route. Instead of starting from simpler precursors and becoming more intricate, say authors Dan McShea and Wim Hordijk, some structures could have evolved from complex beginnings that gradually grew simpler - an idea they dub "complexity by subtraction...
Researchers Discover Clues To Heart Disease In Unexpected Places
Date: Apr-16-2013A major factor in the advance of heart disease is the death of heart tissue, a process that a team of scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine think could be prevented with new medicines. Now, the researchers are one step closer to achieving that goal, thanks to their discovery of a key molecule in an unexpected place in heart cells - mitochondria, tiny energy factories that house the controls capable of setting off cells' self-destruct sequence...
Sleep Apnea Severity Is Higher In African American Men, Particularly In Certain Age Ranges
Date: Apr-16-2013A new study suggests that obstructive sleep apnea severity is higher in African-American men in certain age ranges, even after controlling for body mass index (BMI)...
Decoding The Secrets Of The Gut
Date: Apr-16-2013A new technique based on atomic force microscopy was developed at the Institute of Food Research to help 'read' information encoded in the gut lining. The lining of our gut is an important barrier between the outside world and our bodies. Laid out, the gut lining would cover the area of a football pitch. It must let nutrients from our foods through, but prevent invasion by disease-causing bacteria, at the same time hosting the trillions of beneficial bacteria needed for proper digestion and immune function...
