OCCUPATIONAL EXPOSURES TO BODY FLUIDS AND BEHAVIORS REGARDING THEIR PREVENTION AND POST-EXPOSURE AMONG MEDICAL AND NURSING STUDENTS AT A BRAZILIAN PUBLIC UNIVERSITY

A cross-sectional study was conducted to assess the frequencies and characteristics of occupational exposures among medical and nursing students at a Brazilian public university, in addition to their prevention and post-exposure behavior. During the second semester of 2010, a self-administered semi-structured questionnaire was completed by 253/320 (79.1%) medical students of the clinical course and 149/200 (74.5%) nursing students who were already performing practical activities. Among medical students, 53 (20.9%) suffered 73 injuries, which mainly occurred while performing extra-curricular activities (32.9%), with cutting and piercing objects (56.2%), in the emergency room (39.7%), and as a result of lack of technical preparation or distraction (54.8%). Among nursing students, 27 (18.1%) suffered 37 injuries, which mainly occurred with hollow needles (67.6%) in the operating room or wards (72.2%), and as a result of lack of technical preparation or distraction (62.1%). Among medical and nursing students, respectively, 96.4% and 48% were dissatisfied with the instructions on previously received exposure prevention; 48% and 18% did not always use personal protective equipment; 67.6% and 16.8% recapped used needles; 49.3% and 35.1% did not bother to find out the source patient's serological results post-exposure; and 1.4% and 18.9% officially reported injuries. In conclusion, this study found high frequencies of exposures among the assessed students, inadequate practices in prevention and post-exposure, and, consequently, the need for training in “standard precautions” to prevent such exposures.Estudo transversal foi realizado para verificar, entre estudantes de medicina e de enfermagem de universidade pública brasileira, as frequências e características de exposições ocupacionais e seus comportamentos na prevenção e pós-exposição. Durante o segundo semestre de 2010, questionário autoaplicável e semiestruturado foi completado por 253/320 (79,1%) estudantes de medicina do curso clínico e por 149/200 (74,5%) estudantes de enfermagem que já exerciam atividades práticas. Entre os estudantes de medicina, 53 (20,9%) sofreram 73 acidentes, que ocorreram principalmente em atividades extracurriculares (32,9%), com objetos pérfuro-cortantes (56,2%), na sala de emergência (39,7%) e em decorrência de despreparo técnico ou distração (54,8%). Entre os alunos de enfermagem, 27 (18,1%) sofreram 37 acidentes, que ocorreram principalmente com agulhas ocas (67,6%), no centro cirúrgico ou enfermarias (72,2%) e em decorrência de despreparo técnico ou distração (62,1%). Entre os alunos de medicina e de enfermagem, respectivamente, 96,4% e 48% estavam insatisfeitos com orientações previamente recebidas de prevenção de acidentes, 48% e 18% nem sempre utilizam equipamento de proteção individual, 67,6% e 16,8% reencapam agulhas usadas, 49,3% e 35,1% não se preocuparam em conhecer os exames sorológicos do paciente-fonte pós-exposição e 1,4% e 18,9% relataram o acidente oficialmente. Em conclusão, neste estudo verificaram-se altas frequências de exposições entre os estudantes avaliados, práticas inadequadas na prevenção e pós-exposição e, consequentemente, a necessidade de treinamento nas “precauções padrão” para prevenção de tais exposições

Frequência de exposições ocupacionais, fatores de risco associados e comportamentos inadequados pós-exposições entre estudantes de medicina e de enfermagem de uma universidade pública brasileira

Introduction: Medical and nursing students are at risk of acquiring infections through occupational accidents due to inexperience and lack of skill in procedures with patients. Objective: To determine the frequency of occupational exposures, risk factors and inadequate post-exposure behaviors among these students in a public university of Southeastern Brazil. Methods: This cross-sectional study was performed in the end of the second semester of 2010. To collect demographic data and the frequency of possible occupational accidents and its characteristics, an anonymous, self-administered and semi-structured questionnaire was distributed to all medical students who were in the clinical course, and for all nursing students who had practical activities at a university hospital. This research project was approved by the Research Ethics Committee of the Universidade Federal de Uberlândia. Results: The questionnaire was completed by 253/320 (79.1%) medical students and 149/200 (74.5%) nursing students. Among medical students, 53 (20.9%) had suffered 73 accidents, which occurred mainly in extracurricular activities (33%); with cutting or piercing objects (56.2%); in the emergency room (39.7%); as a result of lack of technical preparation or distraction (54.8%). Among nursing students, 27 (18.1%) suffered 37 injuries, which mainly occurred with hollow needles (67.6%), in the operating room or wards (72.2%), as a result of lack of technical preparation or distraction (62.1%). Among medical and nursing students, respectively, 96.4% and 48% were dissatisfied with the instruction on exposure prevention previously; 48% and 18% did not always use personal protective equipment; 67.6% and 16.8% recapped used needles; 83.8% and 85.2% had no knowledge about the behaviors that should be performed after such exposures; 97.2% and 85.9% were unaware about the behaviors that must be taken in case of contact with body fluids of patients with HIV, HBV and HCV; and 1.4% and 18.9% officially reported injuries. Conclusions: We observed high frequency of occupational exposures among medical and nursing students, low level of knowledge about prevention and post-accidents procedures, and the need for structured training for "standard precautions" to prevent occupational exposures.Mestre em Ciências da SaúdeIntrodução: Estudantes de medicina e de enfermagem estão em risco de adquirir infecções por acidentes ocupacionais devido à inexperiência e a falta de habilidade em procedimentos com pacientes. Objetivo: Verificar as frequências de exposições ocupacionais, fatores de risco associados e de comportamentos inadequados pós-exposições entre esses estudantes de uma universidade pública da região sudeste do Brasil. Métodos: Este estudo transversal foi realizado no final do segundo semestre de 2010. Para coleta de dados sociodemográficos e das frequências de possíveis acidentes ocupacionais e de suas características, um questionário anônimo, autoaplicável e semiestruturado foi distribuído para todos os estudantes de medicina que estavam no curso clínico e para todos os estudantes de enfermagem que já tinham atividades práticas no hospital. O projeto desta pesquisa foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Uberlândia. Resultados: O questionário foi respondido por 253/320 (79,1%) estudantes de medicina e por 149/200 (74,5%) estudantes de enfermagem. Entre os estudantes de medicina, 53 (20,9%) haviam sofrido 73 acidentes, que ocorreram principalmente em atividades extracurriculares (33%), com objetos perfurocortantes (56,2%), na sala de emergência (39,7%) em decorrência de despreparo técnico ou distração (54,8%). Entre os alunos de enfermagem, 27 (18,1%) tinham sofrido 37 acidentes, que ocorreram principalmente com agulhas ocas (67,6%), no centro cirúrgico ou enfermarias (72,2%) e em decorrência de despreparo técnico ou distração (62,1%). Entre os alunos de medicina e de enfermagem, respectivamente, 96,4% e 48% estavam insatisfeitos com as orientações prévias de prevenção de acidentes, 48% e 18% nem sempre utilizavam equipamentos de proteção individual, 67,6% e 16,8% reencapavam agulhas usadas, 83,8% e 85,2% não tinham conhecimento sobre as condutas que devem ser adotadas após tais exposições, 97,2% e 85,9% desconheciam as condutas que devem ser adotadas em caso de contato com fluídos corporais de pacientes portadores de VIH, VHB e VHC e 1,4% e 18,9% relataram o acidente oficialmente. Conclusões: Nós observamos altas frequências de acidentes ocupacionais entre os estudantes de medicina e de enfermagem, baixo nível de conhecimento na prevenção e nas condutas pós-acidente e a necessidade de treinamento estruturado nas precauções padrão para prevenção de exposições ocupacionais

Sensitivity of South American tropical forests to an extreme climate anomaly

NERC Knowledge Exchange Fellowship (NE/V018760/1) to E.N.H.C.The tropical forest carbon sink is known to be drought sensitive, but it is unclear which forests are the most vulnerable to extreme events.

Sensitivity of South American tropical forests to an extreme climate anomaly

Abstract: The tropical forest carbon sink is known to be drought sensitive, but it is unclear which forests are the most vulnerable to extreme events. Forests with hotter and drier baseline conditions may be protected by prior adaptation, or more vulnerable because they operate closer to physiological limits. Here we report that forests in drier South American climates experienced the greatest impacts of the 2015–2016 El Niño, indicating greater vulnerability to extreme temperatures and drought. The long-term, ground-measured tree-by-tree responses of 123 forest plots across tropical South America show that the biomass carbon sink ceased during the event with carbon balance becoming indistinguishable from zero (−0.02 ± 0.37 Mg C ha−1 per year). However, intact tropical South American forests overall were no more sensitive to the extreme 2015–2016 El Niño than to previous less intense events, remaining a key defence against climate change as long as they are protected
