[EX 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.

[EX Q]: We designed and tested an innovative transitional care program, involving cardiac surgery nurse practitioners, to improve care continuity after patient discharge home from coronary artery bypass graft (CABG) operations and decrease the composite end point of 30-day readmission and death.', 'A total of 401 consecutive CABG patients were eligible between May 1, 2010, and August 31, 2011, for analysis. Patient data were entered prospectively into The Society of Thoracic Surgeons database and the New York State Cardiac Surgery Reporting System and retrospectively analyzed with Institutional Review Board approval. The "Follow Your Heart" program enrolled 169 patients, and 232 controls received usual care. Univariate and multivariate analyses were used to identify readmission predictors, and propensity score matching was performed with 13 covariates.', 'Binary logistic regression analysis identified "Follow Your Heart" as the only independently significant variable in preventing the composite outcome (p=0.015). Odds ratios for readmission were 3.11 for dialysis patients, 2.17 for Medicaid recipients, 1.87 for women, 1.86 for non-Caucasians, 1.78 for chronic obstructive pulmonary disease, 1.26 for diabetes, and 1.09 for congestive heart failure. Propensity score matching yielded matches for 156 intervention patients (92%). The intervention showed a significantly lower 30-day readmission/death rate of 3.85% (6 of 156) compared with 11.54% (18 of 156) for the usual care matched group (p=0.023).

[EX Q]: Although N-terminal pro-B-type natriuretic peptide (NT-proBNP) has a strong relationship with incident cardiovascular disease (CVD), few studies have examined whether NT-proBNP adds to risk prediction algorithms, particularly in women.', 'This study sought to evaluate the relationship between NT-proBNP and incident CVD in women.', "Using a prospective case-cohort within the WHI (Women's Health Initiative) observational study, we selected 1,821 incident cases of CVD (746 myocardial infarctions, 754 ischemic strokes, 160 hemorrhagic strokes, and 161 other cardiovascular [CV] deaths) and a randomly selected reference cohort of 1,992 women without CVD at baseline.", 'Median levels of NT-proBNP were higher at study entry among incident cases (120.3 ng/l [interquartile range (IQR): 68.1 to 219.5 ng/l]) than among control subjects (100.4 ng/l [IQR: 59.7 to 172.6 ng/l]; p\xa0< 0.0001). Women in the highest quartile of NT-proBNP (≥140.8 ng/l) were at 53% increased risk of CVD versus those in the lowest quartile after adjusting for traditional risk factors (1.53 [95% confidence interval (CI): 1.21 to 1.94]; p for trend\xa0<0.0001). Similar associations were observed after adjustment for Reynolds Risk Score covariables (1.53 [95% CI: 1.20 to 1.95]; p for trend\xa0<0.0001); the association remained in separate analyses of CV death (2.66 [95% CI: 1.48 to 4.81]; p for trend\xa0<0.0001), myocardial infarction (1.39\xa0[95% CI: 1.02 to 1.88]; p for trend\xa0= 0.008), and stroke (1.60 [95% CI: 1.22 to 2.11]; p for trend\xa0<0.0001). When added to traditional risk covariables, NT-proBNP improved the c-statistic (0.765 to 0.774; p\xa0= 0.0003), categorical net reclassification (0.08; p\xa0< 0.0001), and integrated discrimination (0.0105; p\xa0<\xa00.0001). Similar results were observed when NT-proBNP was added to the Reynolds Risk Score.
