BACKGROUND: Reduced muscular strength is associated with an increased risk of all-cause, cardiovascular and non-cardiovascular mortality, heart attack and stroke. At older ages, reduced strength is associated with impaired mobility, risk of falls, and disability. Various criteria are used to determine reduced strength. DATA AND METHODS: Data on grip strength among 3,181 respondents aged 60 to 79 from the 2007 to 2013 Canadian Health Measures Survey were used to calculate the prevalence of reduced strength based on sex-specific percentile and t-score cut-points and cut-points of the Foundation for the National Institutes of Health...

Objective: Neurofibromatosis type 1 (NF1) causes neural and cutaneous disorders and reduced exercise capacity. Exercise/heat exposure increasing internal temperature must be compensated by eccrine sweat function and warmed skin vasodilation. We suspected NF1 could adversely affect eccrine sweat function and/or vascular thermoregulatory responses (VTR). Methods: The eccrine sweat function and VTR of 25 NF1 volunteers (14 males, 11 females; 16-57 years old) were compared with 23 non-NF1 controls matched by sex, age, height and weight (CG)...

Poor perinatal growth in humans results in asymmetrical grey matter loss in fetuses and infants and increased functional and behavioural asymmetry, but specific contributions of pre- and postnatal growth are unclear. We therefore compared strength and direction of lateralization in obstacle avoidance and maze exit preference tasks in offspring of placentally restricted (PR: 10M, 13F) and control (CON: 23M, 17F) sheep pregnancies at 18 and 40 weeks of age, and examined gross brain structure of the prefrontal cortex at 52 weeks of age (PR: 14M, 18F; CON: 23M, 25F)...

Background and purpose - In a previous registry report, short-term implant survival of hip resurfacing arthroplasty (HRA) in Finland was found to be comparable to that of total hip arthroplasty (THA). Since then, it has become evident that adverse reactions to metal debris (ARMDs) may also be associated with HRA, not only with large-diameter head metal-on-metal THA. The aim of the study was to assess medium- to long-term survivorship of HRA based on the Finnish Arthroplasty Register (FAR). Patients and methods - 5,068 HRAs performed during the period 2001-2013 in Finland were included...

Measurement of serum testosterone (T) levels is recommended in the evaluation of osteoporosis in older men and estradiol (E2) and sex hormone binding globulin (SHBG) levels are associated with the rate of bone loss and fractures, but the clinical utility of sex steroid and SHBG measurements for the evaluation of osteoporosis in men has not been examined. To evaluate whether measurements of T, E2 and/or SHBG are useful for the prediction of fracture risk or the rate of bone loss in older men, we analyzed longitudinal data from 5487 community-based men participating in the MrOS Study in the US, Sweden and Hong Kong...

MicroRNAs (miRNAs) in urine are examined as potential biomarkers. We examined the urine samples from 70 individuals (45 males, 25 females, mean age 65 years, range 20-84 years). Of the urine donors, 15 were healthy volunteers, 5 were patients with non-cancer diseases, 50 were patients with different stages of bladder cancer. To examine the spectrum of miRNAs in the cell-free fraction of urine, TaqMan Human miRNA Array Card A v.2.1 was used. A set of 30 miRNAs were found that are constantly present in urine supernatants independently of sex, age and health status of the subjects...
