Avaliação da contaminação de jalecos de graduandos e profissionais da saúde na Universidade Federal de Uberlândia
Resumo:
- INTRODUCTION: The lab coats are one of the first contamination sites in terms of clothing in the health area that come into contact with the patients' skin, liquids and secretions. In this way they easily carry pathogenic microorganisms from place to place. The present study aimed to assess the contamination of Staphylococcus spp. and to identify the main Gram negative bacilli in lab coats by health professionals and university students. 2. MATERIAL AND METHODS: 148 samples were obtained, which were subjected to Gram stain, catalase test, coagulase, biochemical tests and glucose oxidation and fermentation tests. 3. RESULTS AND DISCUSSION: In total 48 lab coats were contaminated by Gram negative bacilli, 73 by Staphylococcus spp. and 35 by S. aureus. In addition, it was possible to identify the genera Klebsiella, Shigella, Pseudomonas, Enterobacter and Serratia. 4. FINAL REMARKS: Bacteria of great clinical importance were found, leading to the conclusion that lab coats for both professionals and undergraduates are an important source of pathogen transmission and their use should be restricted to the service areas and laboratory environments.

Resumo:
INTRODUCTION: Melatonin, recognized for its influence on sleep regulation, is attracting increasing interest due to its antioxidant properties. Although still under study, it is suggested that this substance may play a beneficial role in preventing hearing loss. REVIEW: A search was carried out in the BIREME, PUBMED AND SCIELO databases by combining the terms: melatonin, hearing, tinnitus, presbycusis, ototoxicity, and their respective terms in English. DISCUSSION: From searches in the databases, 272 articles were retrieved, from which 17 articles that addressed the proposed topic were selected using the exclusion criteria. FINAL REMARKS: It was verified through this review that melatonin can help prevent hearing loss caused by oxidative stress, due to its ability to eliminate free radicals generated in the cochlea.
Keywords: Hearing, Oxidative Stress, Melatonin, Ototoxicity, Hearing Loss, Sensorineural, Tinnitus.
