Introduction: Burnout syndrome is a phenomenon characterized by chronic emotional exhaustion that can lead to physical, psychological, and social consequences. Because they need to support themselves financially, university professors have accepted increasingly longer working hours and accumulated duties, resulting in greater exposure to factors that may induce the onset of mental disorders such as burnout syndrome., Objectives: This cross-sectional epidemiological study aimed to determine the prevalence of burnout syndrome and predisposing factors in university professors working in Salvador, Brazil., Methods: The sample consisted of 210 participants. The Maslach Burnout Inventory adapted for teachers, the gold standard for detecting burnout syndrome, and a sociodemographic questionnaire were administered to identify variables that may influence the development of burnout. Then, the data were compiled in Excel and analyzed with the aid of GraphPad Prism., Results: The prevalence of burnout was 41% (n = 86). A stratified data analysis showed that being under 40 years of age, being single, being childless, teaching natural sciences, and working at several institutions are risk factors for developing burnout syndrome., Conclusions: The prevalence of burnout syndrome in university professors was 41%. Professors who were young, single, childless, taught natural sciences, and worked at more than one institution were found to be more likely to develop burnout syndrome., Competing Interests: Conflicts of interest: None

The increasing use of pharmaceutical products also increases their release in aquatic environment. These contaminants are considered emerging pollutants, and induce adverse ecological and human health effects. The antidiabetic metformin is one example that has been detected in the aquatic environment at unusual concentrations. This fact indicates that conventional wastewater treatment is inefficient on eliminating this compound. Here we show that metformin can be effectively removed from water by photocatalysis. We found the optimised conditions for pH and concentration of catalyst on the photocatalytic process. TiO 2 and TiO 2 -ZrO 2 were successful in oxidising metformin under UV radiation following a pseudo-first order kinetics. Intermediates of metformin photodegradation appeared after photocatalytic treatment. Toxicity analysis showed that the degradation products are non-toxic to Lactuca sativa seeds., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.
