Comparative Analysis of Artery Anatomy Evaluated by Postmortem Tomography, CT Angiography, and Postmortem and Predeath CT Scans.

Background: To date, no study has been performed analyzing changes in the vascular system comparing paired examinations of patients alive and after death with the use of cardiopulmonary bypass and computed tomography (CT) angiography.

Materials And Methods: The aim of this study was to analyze in a large series (38 patients) the aorta and its branches by CT (without contrast) and CT angiography of patients still alive and after death comparing their diameters and length variations.

Results: The variation between in vivo tomography and virtopsy methods was greater in the evaluation of distances between vascular segments than in the diameters; less than 30% of the distances evaluated in the entire study had acceptable variation between methods, regardless of the use of contrast scans.

Accumulation of different shapes of microplastics initiates intestinal injury and gut microbiota dysbiosis in the gut of zebrafish.

Different shapes of microplastics are widely detected in the environment and organisms and most of them remain in the gut. However, the influences of shapes on the bioaccumulation and toxicity of microplastics in the gut are largely unknown. Three shapes (bead, fragment, and fiber) of microplastics of comparable size in one dimension were prepared to exposure to zebrafish.

Epidemiologic analysis of prevalence of the hyperhidrosis.

Background: The present paper aims to study the prevalence of the various manifestations of hyperhidrosis in patients who sought treatment in a specialized ambulatory in the state of São Paulo.

Objectives: Opposite to previous studies, this paper studies the different combinations of sweating sites, not being restricted to the main complaint site of the patients, but taking into consideration secondary complaints patients may present.

Methods: This was a retrospective approach of a database containing more than 1200 patients in which were mapped: combination of sweating sites, age of onset, age spectrum, mean age, body mass index and gender of patients.
