This is a pragmatic, non-randomized controlled trial. Seventy general practitioners (GPs) were selected to provide either ...

Pressure-redistribution surfaces are generally recommended to prevent pressure ulcers (PUs) in high-risk patients, but their use in surgery-related PU prevention remains controversial. A meta-analysis was conducted to assess the relative preventive impact of pressure-redistribution surfaces versus standard hospital mattresses (usually a hospital-issue, foam-based mattress) on the incidence of surgery-related PUs. ...

The efficacy of pressure-heat treatment was evaluated for the inactivation of Bacillus cereus spores in cooked rice. The spores of B. cereus ATCC 9818 were inoculated (1.1 × 10(8) CFU/g) in a parboiled rice product (pH 6.0, water activity of 0.95) and inactivated to an undetectable level (<10 CFU/g) by ...

Correlation between systolic (SBP) and diastolic (DBP) blood pressure (BP) level and target organ damage, cardiovascular disease (CVD) risk, and long-term prognosis is much greater for ambulatory BP monitoring (ABPM) than daytime office measurements. The 2013 ABPM guidelines specified herein are based on ABPM patient outcomes studies and constitute a ...

OBJECTIVES:: Production of nitric oxide by the vascular endothelium is crucial for the maintenance of vascular tone, an important determinant of blood pressure. L-Arginine and its homolog L-homoarginine are competitive substrates of nitric oxide synthase (NOS), whereas asymmetric dimethylarginine (ADMA) is a NOS inhibitor. We evaluated the relationships between physiological ...
