Larvicidal effect of Azadirachta indica on mosquitoes has been studied in the present work. The water extracts of air dried leaves and fresh leaves separately have been used for the study. Different concentrations were made of all these extracts and twenty second instar larvae of Culex pipiens fatigans were placed in each concentration separately. Control was set up for each experiment. Mortali...

BACKGROUND Clinical studies demonstrate that up to 40% of patients do not respond to cardiac resynchronization therapy (CRT), thus, appropriate patient selection is critical to the success of CRT in heart failure. OBJECTIVE Evaluation of mortality predictors and response to CRT in the Brazilian scenario. METHODS Retrospective cohort study including patients submitted to CRT in a tertiary ho...

In the present study, we proposed a modification in one of the most frequently applied effect-size procedures in single-case data analysis: the percentage of nonoverlapping data. In contrast with other techniques, the calculus and interpretation of this procedure are straightforward and can be easily complemented by visual inspection of the graphed data. Although the percentage of nonoverlappin...

Scotland, which has one of the highest death rates in the world from coronary heart disease, also has considerable regional variation in mortality from this cause. The relation between standardised mortality ratios for coronary deaths (1979-83) for 56 local government districts and a range of socioeconomic factors from the 1981 Census as well as climatic factors and water hardness were investig...

OBJECTIVE We assessed the relationship of mortality with glycated hemoglobin (HbA1c) variability and with absolute change in HbA1c. DESIGN A population-based prospective observational study with a median follow-up time of 6 years. METHODS Based on a validated algorithm, 11 205 Danish individuals with type 2 diabetes during 2001-2006 were identified from public data files, with at least thre...

We previously found no significant differences in mortality between men who underwent surgery for localized prostate cancer and those who were treated with observation only. Uncertainty persists regarding nonfatal health outcomes and long-term mortality. From November 1994 through January 2002, we randomly assigned 731 men with localized prostate cancer to radical prostatectomy or observation. ...

BACKGROUND Although essential to guide control measures, published estimates of influenza-related seasonal mortality for low- and middle-income countries are few. We aimed to compare influenza-related mortality among individuals aged ≥65 years in South Africa and the United States. METHODS We estimated influenza-related excess mortality due to all causes, pneumonia and influenza, and other in...
