Two new 2H-pyranones (1 and 2), two new isocoumarins (4 and 5), and two known compounds (3 and 6) were obtained from solid cultures of the endophytic fungus Pestalotiopsis microspora SC3082. Their structures and revision of the absolute stereochemistry of 6 were established by spectroscopic analyses and computational calculations. Compounds 2, 4 and 6 displayed moderate antifungal activities against Candida albicans ATCC 10321 with MIC values of 25.0, 25.0, and 12.5 μg/mL, respectively.Several trials have been completed in patients with heart failure (HF) treated with uric acid (UA)-lowering agents with inconsistent results. We aimed to investigate whether lowering UA would have an effect on mortality and cardiovascular (CV) events in patients with HF in a systematic review and meta-analysis. The primary outcome measures were all-cause mortality, CV mortality, CV events, and CV hospitalization in patients with HF. We included 11 studies in our final analysis. Overall, allopurinol treatment was associated with a significant increase in the risk for all-cause mortality (hazard ratio [HR] 1.24, 95% confidence interval [CI] 1.04-1.49, P = .02). The trial heterogeneity is high (heterogeneity χ2 = 37.3, I2 = 73%, P less then .001). With regard to CV mortality, allopurinol treatment was associated with a 42% increased risk of CV mortality (HR 1.42, 95% CI 1.11-1.81, P = .005). There was a trend toward increased CV hospitalization in the same group (HR 1.21, 95% CI 0.95-1.53, P = .12). read more Uric acid-lowering treatments increase all-cause and CV mortality but did not increase CV hospitalization significantly in this study.Objective To develop and evaluate the validity of a self-report measure of sleep practices for youth 8-17 years.Methods Following recommended guidelines for the development of patient reported outcomes (PROs), sleep practice concepts were identified through expert (n = 8) and child (n = 28) concept elicitation interviews and a systematic literature review. Items were developed based on these concepts and tested in cognitive interviews with children (n = 32). Psychometric analyses were applied to item response data collected from a diverse sample of youth 8-17 years (n = 307). Construct validity was evaluated through tests of associations between sleep practices and sleep disturbance and sleep-related impairment. Finally, clinical validity of the tool was assessed by comparing scores of youth with and without a parent-identified sleep problem.Results The final Pediatric Sleep Practices Questionnaire (PSPQ) included 15 items that were used to identify 5 sleep practices sleep timing, sleep routines and consistency, technology use before bedtime, sleep environment, and the need for parental presence to fall asleep. A confirmatory factor analysis supported the hypothesized structure (all factor loadings ≥ 0.72) and PSPQ indices were significantly associated with self-reported sleep disturbances and sleep-related impairment. Finally, children with parent-reported sleep problems had shorter sleep opportunity, later bedtimes, greater need for parental presence, poorer bedtime routines, and more technology use than children without parent-reported sleep problems.Conclusions The PSPQ was developed using best-practice PRO development methodology. The PSPQ can be used in clinical settings and for research assessment to capture modifiable sleep practices that may promote or interfere with healthy sleep.The Hispanic population has one of the highest levels of untreated oral disease of any linguistic or ethnic population in the United States. Research examining the factors leading to such outcomes is limited. Since health literacy has been identified as a mediator of health disparities, it is important to identify the most appropriate tool to assess it. The Knowledge Related to Oral Health Literacy model for Spanish speakers (KROHL-S) is an inclusive framework to evaluate oral health knowledge and other modifiable factors at the individual level among the Hispanic population as related to oral health literacy. KROHL-S intends to provide concrete, practical information to help customize interpersonal interactions and educational experiences to individuals' needs and capabilities. The questionnaire that will allow the creation of the KROHL-S scale consists of orally administered open-ended questions to measure knowledge that is condition specific (caries, periodontal disease, oral cancer, tooth loss, and malocclusion) and domain that is knowledge specific (identification of condition, causes, prevention, treatment, general knowledge). Implementation of the KROHL-S framework will provide in depth information that could be shared among health care providers and the creation of patient-centred initiatives.Background Catheter ablation for ventricular tachycardia (VT) reduces the recurrence of VT in patients with implanted cardioverter-defibrillators (ICDs). The appropriate timing of VT ablation and its effects on mortality and heart failure progression remain a matter of debate. In patients with life-threatening arrhythmias necessitating ICD implantation, we compared outcomes of preventive VT ablation (undertaken before ICD implantation in order to prevent ICD shocks for VT) and deferred ablation after three ICD shocks for VT. Methods The Preventive Ablation of Ventricular Tachycardia in Patients with Myocardial Infarction (BERLIN VT) study was a prospective, open, parallel, randomized trial performed at 26 centers. Patients with stable ischemic cardiomyopathy, a left ventricular ejection fraction between 30% and 50%, and documented VT were randomly assigned 11 to a preventive or deferred ablation strategy. The primary outcome was a composite of all-cause death and unplanned hospitalization for either symptomatricular tachyarrhythmia (39.7% vs. 48.2%; P=0.050) and appropriate ICD therapy (34.2% vs. 47.0%; P=0.030) were numerically reduced in the preventive ablation group. Conclusions Preventive VT ablation before ICD implantation did not reduce mortality or hospitalization for arrhythmia or worsening heart failure during 1 year of follow-up when compared to the deferred ablation strategy.
