[Q]: Microvascular alterations contribute to the development of stroke and vascular dementia. The goal of this study was to evaluate age and hypertension related changes of the basal lamina in cerebral microvessels of individuals, who died from non-cerebral causes.', 'We examined 27 human brains: 11 young and 16 old patients. Old patients were divided into two subgroups, those with hypertension (n = 8) and those without hypertension (n = 8). Basal lamina changes of the cerebral microvessels were determined in the putamen using antibodies against collagen type IV and by quantitative analysis of vessel number, total stained area of collagen, thickness of the vessel wall and lumen, and relative staining intensity using immunofluorescence. The total number of collagen positive vessels per microscopic field was reduced in old compared to young subjects (12.0+/-0.6 vs. 15.1+/-1.2, p = 0.02). The relative collagen content per vessel (1.01+/-0.06 vs. 0.76+/-0.05, p = 0.01) and the relative collagen intensity (233.1+/-4.5 vs. 167.8+/-10.6, p < 0.0001) shown by immunofluorescence were higher in the older compared to the younger patients with a consecutive reduction of the lumen / wall ratio (1.29+/-0.05 vs. 3.29+/-0.15, p < 0.0001). No differences were observed for these parameters between old hypertensive and non-hypertensive patients.

[Q]: The effect of alcohol consumption on the liver is controversial. Recent reports have suggested that moderate alcohol consumption decreases the prevalence of elevated alanine aminotransferase levels. The role of alcohol consumption in the development of fatty liver (FL), however, has not been studied definitively. The aim of this study was to examine the association between alcohol consumption and FL in a large Japanese population.', 'A total of 7,431 asymptomatic male subjects who underwent a complete medical survey in our institute between May 2007 and July 2008 were recruited. Cases positive for hepatitis B or C viruses, potential hepatotoxic drug intake, or under treatment for metabolic disorders were excluded. FL was defined by ultrasonography. Visceral and subcutaneous adipose tissues (VAT and SAT) were measured by computed tomography. Independent and significant predictors associated with FL were determined by multiple logistic regression analysis.', 'Of the initial study candidates, 130 (1.7%) were positive for hepatitis B and 66 (0.8%) were positive for hepatitis C. On the basis of the inclusion and exclusion criteria, 5,599 men (50.9+/-8.1 years) were studied cross-sectionally. Light (40-140 g/week) and moderate (140-280 g/week) alcohol consumption significantly and independently reduced the likelihood of FL (odds ratio=0.824 and 0.754, 95% confidence interval=0.683-0.994 and 0.612-0.928, P=0.044 and 0.008, respectively) by multivariate analysis after adjusting for potential confounding variables. VAT, SAT, low-density lipoprotein, triglycerides, and fasting blood glucose were significant predictors of the increased prevalence of FL, whereas age was a predictor of the decreased prevalence of FL.

[Q]: This study aimed at (1) comparing the prevalence of generalized hypermobility in patients with chronic fatigue syndrome (CFS) and healthy volunteers, (2) examining the clinical importance of generalized hypermobility in patients with CFS, and (3) examining whether knee proprioception is associated with hypermobility in patients with CFS.', 'Sixty-eight patients with CFS filled out two self-reported measures (for the assessment of symptom severity and disability), were questioned about muscle and joint pain, and were screened for generalized hypermobility. Afterward, the patients performed a knee repositioning test (assessment of knee proprioception), and it was examined whether or not they fulfilled the criteria for benign joint hypermobility syndrome (BJHS). Sixty-nine age- and sex-matched healthy volunteers were screened for generalized joint hypermobility and performed the same knee repositioning test.', 'Compared with the healthy volunteers (4.3%, 3/68), significantly more patients with CFS (20.6%, 14/69) fulfilled the criteria for generalized joint hypermobility (Fisher exact test, P < .004). No associations were found between generalized joint hypermobility and the self-reported measures (including pain severity) or knee proprioception (Spearman correlation analysis). Knee proprioception was similar in both groups (Mann-Whitney U = 1961, z = -1.745, P = .81). Forty patients with CFS (58.8%) fulfilled the criteria for BJHS.
