Cardiovascular risk among health professionals working in pre-hospital care services

The objective of this study was to assess the cardiovascular risk factors among health professionals, particularly hypertension, and stratify them according to the Framingham Risk Score (FRS). The participants were 154 professionals working in pre-hospital care in Sao Paulo, Brazil, and on the Br-116 highway. Values were considered significant for p<0.05. The prevalence of hypertension was 33%, 20.1% were smokers, 47% consumed alcoholic beverages, 64% were sedentary, 66% were obese/overweight and 70% had an altered abdominal circumference. In terms of laboratory values: glucose >= 110mg/dL11%, total cholesterol >= 200mg/dL-36%, LDL-c >= 130mg/dL-33%, HDL-c<60mg/dL89%, triglycerides >= 150mg/dL-30% and C reactive protein >= 0.5mg/dL-16%. The FRS was average in 10.3% and high in 1.3%. In logistic regression analysis, it was verified that hypertension was associated with: HDL-c (odds ratio: 0.257,) and FRS (odds ratio: 23.159). There was strong correlation between hypertension and FRS. Data are noteworthy, as this is a relatively young sample of health professionals.

Toxicity of synthetic and natural compounds on Tetranychus urticae and the predator Phytoseiulus macropilis

The objective of this work was to evaluate the toxicity of synthetic and natural compounds on Tetranychus urticae and the predator Phytoseiulus macropilis. Mortality and growth rates of T. urticae and its predator were evaluated after applications of: abamectin, clofentezine, fenpropathrin, fenpyroximate, propargite, sulfur and spiromesifen, at their recommended concentrations; neem oils (Natuneem and Sempre Verde Killer Neem at 1%); and aqueous extracts at 10% of Dieffenbachia brasiliensis, Annona squamosa, Ruta graveolens, Agave angustifolia, Melia azedarach, Sonchus oleraceus, Mentha spicata x M. suaveolens, Allium cepa, Laurus nobilis, and Eucalyptus saligna. The acute toxicity and the influence of the compounds on the instantaneous growth rate of the mites were carried out in laboratory. Extracts of A. cepa, A. angustifolia, neem oil-based products, spiromesifen, propargite, fenpyroximate, abamectin and fenpropathrin caused mortality higher than 83% on T. urticae. Extract of A. angustifolia, Natuneem and clofentezine did not cause significant mortality rates on P. macropilis. Agave angustifolia and Natuneem did not affect significantly the growth rate of this predator. Propargite, fenpyroximate, abamectin, fenpropathrin, spiromesifen and extract of L. nobilis severely affected P. macropilis population.
