Hyperglycemia could cause Type 2 diabetes in acutely ill patients, study finds
NEW YORK Heightened blood sugar during critical illnesses could be a sign of risk for Type 2 diabetes, according to a recent study by researchers in Croatia.
The study, conducted by researchers at University Hospital Centre Rebro and published in the journal Critical Care, followed 591 patients for five years after their discharge, dividing them into a group of 398 who had normal blood sugar levels during their hospital stays, and a group of 193 who developed hyperglycemia during their stays. Of the patients with normal blood sugar, 14 developed Type 2 diabetes, while among those who had hyperglycemia, 33 developed the disease.
“Despite the fact that endocrine and metabolic changes probably occur in all acutely ill patients, evident hyperglycemia is not always present,” lead researcher Ivan Gornik said. “We hypothesized that hospital-acquired hyperglycemia can therefore reveal a patient’s predisposition to impaired glucose control, which could in [the] future lead to diabetes.”
Study unveils prevalence of condom use among Americans
BLOOMINGTON, Ind. Condom use is higher among black and Hispanic Americans than among white Americans and those from other racial groups, according to findings from the largest nationally representative study of sexual and sexual health behaviors ever fielded, conducted by Indiana University sexual health researchers and published last week in a special issue of the Journal of Sexual Medicine.
The study helped both the public and professionals to understand how condom use patterns vary across these different stages in people’s relationships and across ages, noted Debby Herbenick, associate director of the Center for Sexual Health Promotion, which conducted the study. "Findings show that condoms are used twice as often with casual sexual partners as with relationship partners, a trend that is consistent for both men and women across age groups that span 50 years."
One new feature to the study was the inclusion of teens — the study found that many teenagers actually practice abstinence. "Many surveys of adolescent sexual behavior create an impression that adolescents are becoming sexually active at younger ages, and that most teens are sexually active," noted Dennis Fortenberry, professor of pediatrics in the IU School of Medicine, who led the adolescent aspects of the study. "[But] many contemporary adolescents are being responsible by abstaining or by using condoms when having sex."
Another key finding highlighted in the collection of papers addressed intimacy health among older Americans, finding that many older adults continue to have active sex lives; however, adults older than 40 years have the lowest rates of condom use.
New PowerBar High Intensity rolls into retail
FLORHAM PARK, N.J. Nestle Performance Nutrition on Tuesday announced its entry into the sport dietary supplement category with the launch of a line of dietary supplements under the brand PowerBar Elite Series High Intensity. Formulated with sustained-release beta alanine for endurance, the line will carry the NSF Certified for Sport certification for sports nutrition products.
"With studies published in the last couple of years, the amino acid beta alanine appears to be joining a small list of nutritional ingredients with good scientific support for helping athletes perform at their best," stated Eric Zaltas, business development director for Nestle Performance Nutrition. "Providing the sustained-release form of beta alanine and gaining NSF certification were important considerations for us as we move into the sports dietary supplement category."
Studies suggest beta alanine supplementation can enhance performance in efforts lasting between one minute and 10 minutes, such as cycling over the top of a hill, high-intensity interval training or in sports events falling within this range.
Each PowerBar High Intensity two-tablet serving provides 1.6 g of beta alanine. For optimum results, athletes should take two tablets twice daily for the first four weeks and two tablets once per day thereafter. With this regimen, athletes typically see results in four to eight weeks.
The supplement started shipping in September through sports specialty retailers and PowerBar.com for a suggested retail price of $39.99 per 56-serving bottle.
