In Brazil, Aedes aegypti resistance to temephos, used since 1967, was detected in several municipalities in 2000. Organophosphates were substituted by pyrethroids against adults and, in some localities, by Bti against larvae. However, high temephos resistance ratios were still detected between 2001 and 2004. Field-simulated assays confirmed a low temephos residual effect. Acethylcholinesterase and Mixed Function Oxidase profiles were not altered. In contrast, higher Esterase activity, studied with three substrates, was found in all examined populations collected in 2001. From 2001 to 2004, a slight reduction in alpha-Esterase (EST) and beta-EST activity together with a gradual increase of p-nitrophenyl acetate (PNPA)-EST was noted. Gluthathione-S-transferase alteration was encountered only in the northeast region in 2001, spreading the entire country thereafter. In general, except for alpha-EST and beta-EST, only one enzyme class was altered in each mosquito specimen. Data are discussed in the context of historic application of insecticides in Brazil.

Erectile Dysfunction (ED) is the leading cause of sexual dysfunction affecting hundreds of millions of men worldwide, and has been described as an important public health problem. The association of five novel anthropometrics related to obesity, lipids and glucose with ED remains unclear. To investigate the association of lipid accumulation products index (LAP), triglyceride glucose index (TyG), waist triglyceride index (WTI), weight-adjusted-waist index (WWI) and a body shape index (ABSI) with ED.

Background: Increasing evidence suggests that a diet rich in antioxidants may prevent erectile dysfunction (ED), but the impact of comprehensive dietary antioxidants on ED has been little studied.
Aim: To investigate the association between the composite dietary antioxidant index (CDAI) and ED risk in adult men.
Methods: The study performed a cross-sectional analysis using data from the 2001-2004 National Health and Nutrition Examination Survey to investigate the association between the composite dietary antioxidant index (CDAI) and ED.

Importance: Heterogeneity in development of estrogen receptor (ER)-specific first primary breast cancer exists due to deleterious germline variants in moderate- to high-penetrance breast cancer susceptibility genes, but it is unknown if these associations occur in ER-specific CBC.
Objective: To determine the association of deleterious germline variants in breast cancer susceptibility genes with ER-specific CBC development and whether ER status of the first primary breast cancer modifies these associations.
Design, Setting, And Participants: This case-control study included CBC cases and matched unilateral breast cancer controls from The Women's Environment, Cancer, and Radiation Epidemiology (WECARE) Study, a population-based case-control study.
Have People Treated With Antihypertensives Been Diagnosed With Hypertension? A Cross-Sectional Study in Stockholm, Sweden.

Purpose: Studies on antihypertensive treatment are important, as hypertension remains the major risk factor for cardiovascular morbidity and premature death. However, antihypertensive medicines are also used for other conditions, and the use of these medicines as a proxy for a diagnosis of hypertension might lead to misclassification in pharmacoepidemiological studies. This study aimed to investigate to what extent people dispensed antihypertensive medicines have been diagnosed with hypertension.
