SURGICAL SITE INFECTION IN RESECTIONS OF DIGESTIVE SYSTEM TUMOURS.

Postoperative infectious complications are extremely important to surgeons and the entire medical care team. Among these complications, surgical site infection (SSI) appears to be one of the earliest and most prevalent events and is considered an inherent complication of surgical procedures. In oncological patients submitted to resections of digestive system tumors, there is a confluence of several risk factors for SSI, making it necessary to establish measures to maximize the control of this condition to provide a better prognosis for these patients.

Determination of ethylene-bis-dithiocarbamates and their degradation product ethylenethiourea in dry herbs by UHPLC-MS/MS.

Dithiocarbamates are a class of fungicides widely used in many countries. In this study, methods for determining the ethylene-bis-dithiocarbamate (EBDC) subclass, and their degradation product ethylenethiourea (ETU) were validated by UHPLC-MS/MS in different types of dry herbs, which can be used as food and/or medicinal purposes. Mancozeb was used in the validation of the EBDC method, where it was initially complexed with EDTA, derivatized, extracted with dimethyl sulfate in acetonitrile, magnesium sulfate (MgSO), and sodium chloride (NaCl), and then purified using primary secondary amine (PSA).

Target analysis of psychoactive drugs in oral fluid by QuEChERS extraction and LC-MS/MS.

This study aimed to validate a modified QuEChERS method, followed by liquid chromatography-tandem mass spectrometry, for the determination of 51 psychoactive substances and screening of 22 ones in oral fluid from electronic dance music party (EDM) attendees. Unstimulated oral fluid was collected in a polypropylene tube and stored in a glass vial at -20 ºC. The sample was extracted with acetonitrile:water and MgSO/NaOAc, followed by cleanup with primary secondary amine and MgSO.

Consumers' Trust in Different Sources of Information Related to Food Hazards and Their Judgment of Government Performance-A Cross-Sectional Study in Brazil.

Trust in institutions is fundamental for the stability and proper functioning of democracies, particularly in matters of high public sensitivity, such as food safety. This study aimed to assess trust levels in different sources of information and respondents' evaluation of the performance of government agencies responsible for controlling food-related hazards. Individuals interviewed in three environments (hospitals/clinics, supermarkets, universities, = 1000) answered a face-to-face questionnaire in the Federal District of Brazil, and another population (health surveillance employees at the municipal, state and federal levels; = 1017) answered the questionnaire online.
