RESUMO

Introdução: Os acidentes ocupacionais com material biológico representam um problema de saúde pública. A exposição ocupacional dos profissionais da saúde configura-se como um risco de transmissão de diversos patógenos. Na literatura, há carência de estudos que analisem o perfil dos acidentes com material biológico nos médicos da atenção primária. Objetivo: Buscou-se compreender o perfil epidemiológico dos acidentes com material biológico em médicos da atenção primária em Minas Gerais. Métodos: Estudo epidemiológico descritivo com análise do perfil dos acidentes com material biológico em médicos da atenção primária em Minas Gerais, utilizando dados secundários. Resultados: No período analisado, foram registrados 111 acidentes com material biológico, dos quais 54% ocorreram somente em 2020 e 2021. A maioria dos casos deu-se em mulheres (59%), e os tipos mais frequentes de exposição foram mucosa (38%) e percutânea (33%). Dos médicos, 23% não possuíam esquema vacinal contra a hepatite B completo. Em média, em 36% dos acidentes os testes sorológicos foram negativos e em 61% não foram realizados ou o campo foi ignorado/deixado em branco. Em apenas 7,2% dos casos a quimioprofilaxia foi indicada, mas ressaltam-se os registros ignorados ou em branco. Mais da metade dos acidentados não emitiu a Comunicação de Acidente de Trabalho (CAT). Conclusões: Os acidentes com material biológico predominam em médicas e nas formas de exposição mucosa e percutânea. Investimentos em medidas de biossegurança e educação permanente são necessários para prevenir casos e estimular sua notificação.

Introduction: Occupational accidents with biological material represent a public health problem. The occupational exposure of health professionals represents a risk of transmission of various pathogens. In the literature, there is a lack of studies that analyze the profile of accidents with biological material among primary health care physicians. Objective: We aimed to understand the epidemiological profile of accidents involving biological material among primary health care physicians in Minas Gerais, Brazil. Methods: Descriptive epidemiological study that analyzed the profile of accidents with biological material among primary health care doctors in Minas Gerais, using secondary data. Results: In the period analyzed, 111 accidents with biological material were recorded, of which 54% occurred only in 2020 and 2021. Most cases occurred in women (59%) and the most frequent types of exposure were mucosal (38%) and percutaneous (33%). About a quarter (23%) of physicians did not have a complete immunization record for hepatitis B. On average, in 36% of accidents serological tests were negative and in 61% they were not performed or the field was ignored/left blank. In only 7.2% of cases, chemoprophylaxis was indicated, but ignored or blank records stood out. More than half of the victims did not fill out a work accident report. Conclusions: Accidents with biological material predominate in female doctors and in forms of mucosal and percutaneous exposure. Investments in biosafety measures and permanent education are necessary to prevent cases and encourage their notification.

El objetivo del presente estudio fue explorar la prevalencia de estos tipos de acoso en residentes de cirugía colombianos. Métodos. Estudio nacional, de corte transversal, realizado en los veinte programas de residencia del país en septiembre de 2023. Los residentes autoevaluaron su exposición a ambas formas de acoso mediante cuestionarios validados. Se realizaron comparaciones entre víctimas y no víctimas de acoso, en función de las características demográficas de la población. Se evaluó la frecuencia de conductas de acoso laboral cometidas por diferentes perpetradores. Resultados. Se incluyeron 238 residentes (64,7 % del total de la población). Las tasas de acoso laboral y sexual fueron de 35,3 % y 18,1 %, respectivamente. Ambos tipos de acoso fueron significativamente mayores en los programas ubicados en el centro del país. El acoso sexual fue significativamente mayor entre las mujeres. Los profesores de cirugía y los residentes de niveles superiores fueron los principales perpetradores de conductas de acoso laboral. Conclusiones. El acoso laboral y sexual es altamente prevalente en la formación de los cirujanos colombianos. Estos hallazgos deben alertar a profesores, médicos residentes y otros grupos de interés, para fomentar ambientes y cultura educativa saludables, que permitan disminuir la prevalencia de estos comportamientos.

Introduction. Workplace and sexual harassment are latent problems during surgical training, which have negative repercussions at the individual, organizational and health system levels. The objective of the present study was to explore the prevalence of these types of harassment in all Colombian surgical residents. Methods. National cross-sectional study conducted in twenty residency programs in September 2023. Residents self-assessed their exposure to both forms of harassment using validated questionnaires. Comparisons were made between victims and non-victims of bullying, based on the demographic characteristics of the population. The frequency of workplace harassment behaviors committed by different perpetrators was evaluated. Results. A total of 238 residents were included (64.7% of population). Rates of workplace and sexual harassment were 35.3% and 18.1%, respectively. Both types of harassment were significantly higher in programs located in the central region of the country. Sexual harassment was significantly higher among women. Surgery professors and senior residents were the main perpetrators of workplace bullying behaviors. Conclusions. Workplace and sexual harassment is highly prevalent during surgical training of Colombian surgeons. These findings should alert professors, residents, and other interest groups to promote healthy educational environments and culture, which will reduce the prevalence of these behaviors.

RESUMO

Abstract In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD's etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety.

Resumo Nas últimas décadas, uma epidemia de doença renal crônica (DRC) tem sido associada a fatores ambientais e ocupacionais (estresse térmico decorrente de cargas de trabalho elevadas em altas temperaturas e exposição a produtos químicos, como agrotóxicos e metais), denominada DRC de origem não tradicional (DRCnt). Esta revisão descritiva tem como objetivo apresentar evidências recentes sobre estresse térmico, agrotóxicos e metais como possíveis causas de DRCnt e fornecer uma visão geral das estratégias brasileiras de regulamentação, fiscalização e vigilância sanitária relacionadas. Os trabalhadores brasileiros são comumente expostos a condições extremas de calor e outros fatores de risco de DRCnt, incluindo o aumento da exposição a agrotóxicos e metais. Além disso, há uma falta de regulamentação e fiscalização, políticas públicas e estratégias adequadas para proteger a saúde renal dos trabalhadores em relação aos principais fatores de risco. É provável que a DRCnt seja uma causa significativa de DRC no Brasil, uma vez que a etiologia da doença é desconhecida em muitos pacientes e diversas condições para seu desenvolvimento estão presentes no país. Estudos epidemiológicos devem ser realizados para explorar associações causais e estimar o impacto do calor, dos agrotóxicos e dos metais na DRCnt no Brasil. Além disso, as políticas públicas devem priorizar a redução da exposição dos trabalhadores e a promoção de sua saúde e segurança.

RESUMO

Brazil is one of the world's largest consumers of pesticides. This intense use impacts the environment and exposes a wide range of individuals to pesticides, including rural workers who are occupationally exposed and rural residents who are environmentally exposed. We aimed to evaluate the effects of occupational exposure to pesticides on the health of rural workers and rural residents. We conducted an epidemiological study with 104 farmers and 23 rural residents of Casimiro de Abreu (Rio de Janeiro, Brazil). A comparison group (urban residents) comprised 103 residents of the urban area of the same city. We determined the activity of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) using a modified version of Ellman's method to evaluate exposure. In addition, we performed genotoxic and mutagenic analyses with the comet assay and the cytokinesis-block micronucleus (CBMN) assay. There was a reduction in cholinesterase activity, mainly BChE, in rural workers and rural residents compared with urban residents (p = 0.002). There was an increase in genotoxic effects in rural workers compared with urban residents (comet assay, p < 0.001; CBMN assay, p < 0.001). In addition, there was a greater chance of genotoxic changes in rural workers exposed to pesticides based on the comet assay (odds ratio [OR] 7.6, 95 % confidence interval [CI] 6.6-15.9) and the CBMN assay (OR 22.7, 95 % CI 10.3-49.9). We found that individuals occupationally exposed to pesticides are more likely to have genotoxic effects. These findings are useful for the development of programs to monitor populations exposed to genotoxic substances and allow the development of strategies for the prevention, control, and surveillance of effects that result from occupational and environmental exposures to pesticides.

RESUMO

INTRODUCTION: Veterinary oncology is constituted mainly by human-use drugs with hazardous agents. Occupational risks are present in all stages of handling. Many studies highlighted that veterinarians and pharmacists staff present a lack of knowledge and insufficient structure for promoting safety practices. This study investigated the professional profile and structure of veterinary antineoplastic chemotherapy in Brazilian services. METHODS: A nationwide survey was carried out through digital platforms by a self-applicable from 2020 to 2021. The characteristics of the structure, facilities, professional profiles, practices related to antineoplastic chemotherapy services, and inspections provided by regulatory companies were investigated. Frequency and ranges were used to examine and describe data. RESULTS: This study analyzed 108 respondents from all Brazilian regions where 36 participants worked in veterinary oncology. Dogs and cats comprised more than 90% of animals assisted. Vincristine, doxorubicin, carboplatin, vinblastine, and cyclophosphamide were the most commonly used drugs. Considering pharmacists-led (n = 4) vs veterinarians-led (n = 18) services, structure with safety for handling hazardous drugs (4 vs 9), correct PPE usage (3 vs 0), and occurrence of occupational accident (0 vs 5) were registered. Almost 60% were dissatisfied with the structure and the managerial unwillingness to promote facility improvements. The majority of participants reported an absence of service inspection. CONCLUSION: The results demonstrated worrying concerning the inadequacy of the physical structure of the facilities, human resources, and handling hazardous drugs increased occupational health risk. The lack of competent authority standards and supervision corroborates practices that expose professionals, the population, and the environment to hazardous agents.

RESUMO

BACKGROUND: Feedback is an essential tool for learning and improving performance in any sphere of education, including training of resident physicians. The learner's perception of the feedback they receive is extremely relevant to their learning progress, which must aim at providing qualified care for patients. Studies pertinent to the matter differ substantially with respect to methodology, population, context, and objective, which makes it even more difficult to achieve a clear understanding of the topic. A scoping review on this theme will unequivocally enhance and organize what is already known. OBJECTIVE: The aim of this study is to identify and map out data from studies that report surgical residents' perception of the feedback received during their education. METHODS: The review will consider studies on the feedback perception of resident physicians of any surgical specialty and age group, attending any year of residency, regardless of the type of feedback given and the way the perceptions were measured. Primary studies published in English, Spanish, and Portuguese since 2017 will be considered. The search will be carried out in 6 databases and reference lists will also be searched for additional studies. Duplicates will be removed, and 2 independent reviewers will screen the selected studies' titles, abstracts, and full texts. Data extraction will be performed through a tool developed by the researchers. Descriptive statistics and qualitative analysis (content analysis) will be used to analyze the data. A summary of the results will be presented in the form of diagrams, narratives, and tables. RESULTS: The findings of this scoping review were submitted to an indexed journal in July 2024, currently awaiting reviewer approval. The search was executed on March 15, 2024, and resulted in 588 articles. After the exclusion of the duplicate articles and those that did not meet the eligibility criteria as well as the inclusion of articles through a manual search, 13 articles were included in the review. CONCLUSIONS: Conducting a scoping review is the best way to map what is known about a subject. By focusing on the feedback perception more than the feedback itself, the results of this study will surely contribute to gaining a deeper understanding of how to proceed to enhance internal feedback and surgical residents' learning progress.

RESUMO

Introdução: a relação entre voz e trabalho é objeto de estudo constante. Ainda não há investigação sobre a relação de monotonia e autonomia com queixas vocais. Objetivo: investigar a relação entre a monotonia e a autonomia no ambiente de trabalho com o surgimento de queixas vocais entre professores. Método: estudo exploratório, qualitativo e descritivo, realizado a partir de grupo focal considerando o ineditismo da temática do estudo. Dez professores triados em estudo anterior com suspeita de distúrbio de voz pelo Índice de Triagem de Distúrbio de Voz, que indicaram percepção de monotonia e falta de autonomia no ambiente de trabalho por meio do instrumento Condições de Produção Vocal de Professores foram convidados a participar. Sete professores aceitaram e foram conduzidos dois grupos focais. Perguntas disparadoras sobre monotonia e autonomia no ambiente de trabalho foram feitas. Após análise de conteúdo, foram criadas quatro categorias principais e subcategorias de análise. Resultados: os participantes debateram questões relacionadas à quebra de expectativas sobre o trabalho, frustrações, rotina e desafios diários. Considerações sobre a voz estavam relacionadas ao uso repetitivo e por longos períodos e ambiente com acústica desfavorável. Queixas como rouquidão e baixa projeção vocal foram citadas. Conclusão: monotonia no ambiente de trabalho foi percebida como algo repetitivo e as relações com o surgimento de queixas vocais podem estar relacionadas a situações de uso da voz de forma intensa e constante. A falta de autonomia parece ocasionar a monotonia e, consequentemente, desmotivação, frustração com a carreira e adoecimento, dentre eles, o distúrbio de voz. (AU)

Introduction: the relationship between voice and work is the subject of constant study. There is still no investigation into the relationship between monotony and autonomy and vocal complaints. Objective:to investigate the relationship between monotony and autonomy in the workplace with the emergence of vocal complaints among teachers. Method: exploratory, qualitative and descriptive study, carried out through a focus group considering the novelty of the study theme. Ten teachers screened in a previous study with suspected voice disorders using the Voice Disorder Screening Index, who indicated a perception of monotony and lack of autonomy in the work environment using the Teacher Vocal Production Conditions instrument were invited to participate. Seven teachers accepted and two focus groups were conducted. Triggering questions about monotony and autonomy in the workplace were asked. After content analysis, four main categories and subcategories of analysis were created. Results: participants discussed issues related to broken expectations about work, frustrations, routine and daily challenges. Considerations about the voice were related to repetitive use for long periods and an environment with unfavorable acoustics. Complaints such as hoarseness and low vocal projection were cited. Conclusion: monotony in the work environment was perceived as something repetitive and the relationship with the emergence of vocal complaints may be related to situations of intense and constant use of the voice. The lack of autonomy seems to cause monotony and, consequently, demotivation, frustration with one's career and illness, including voice disorders. (AU)

RESUMO

BACKGROUND: Occupational hand and wrist injuries (OHWIs) account for 25% of work-related accidents in low- and middle-income countries. In Colombia, more than 500000 occupational accidents occurred in 2021, and although the rate declined to less than 5% in 2020 and 2021, at least one in four accidents involved a hand or wrist injury. AIM: To describe the OHWIs in workers seen at the emergency room at a second-level hospital in Colombia. METHODS: An observational study was performed using data from workers who experienced OHWIs and attended a second-level hospital, between June, 2020 and May, 2021. The overall frequency of OHWIs, as well as their distribution by sociodemographic, clinical, and occupational variables, are described. Furthermore, association patterns between sex, anatomical area (fingers, hand, wrist), and type of job were analyzed by correspondence analysis (CA). RESULTS: There were 2.101 workers treated for occupational accidents, 423 (20.3%) were cases of OHWIs, which mainly affected men (93.9%) with a median age of 31 years and who worked mainly in mining (75.9%). OHWIs were more common in the right upper extremity (55.3%) and comprised different types of injuries, such as contusion (42.1%), laceration (27.9%), fracture (18.7%), and crush injury (15.6%). They primarily affected the phalanges (95.2%), especially those of the first finger (25.7%). The CAs showed associations between the injured anatomical area and the worker's job that differed in men and women (explained variance > 90%). CONCLUSION: One out of five workers who suffered occupational accidents in Cundinamarca, Columbia had an OHWI, affecting mainly males employed in mining. This occupational profile is likely to lead to prolonged rehabilitation, and permanent functional limitations. Our results might be useful for adjusting preventive measures in cluster risk groups.

RESUMO

The objectives of this study were to assess the adequacy of physical parameters/factors (temperature, relative humidity, noise, and illuminance levels) of the work environment in PHC facilities, to evaluate the association between the adequacy of these measured physical parameters and the physical characteristics of the PHC facilities and their surroundings and to assess the association between health professionals' perceptions about exposure to physical risks in the PHC work environment and the adequacy of physical parameters measured in the same facilities. The study monitored 23 PHC facilities in southern Brazil and interviewed 210 health professionals. Data analysis involved Pearson's chi-square, Fisher's exact test, Spearman's correlation, and multivariate linear regression analysis was used to control for confounding factors. The significance level was set at 5% (p ≤ 0.05). The combination of temperature and relative humidity presented thermal comfort levels outside the adopted criteria for adequacy in consultation (outdoor relative humidity, p = 0.013) and procedure rooms (front door open, p = 0.034). Inadequate sound comfort (noise) levels in the morning shift were found in the vaccination (front door open, p = 0.021) and consultation rooms (movement of people, p = 0.016). In PHC facilities where reception rooms had insufficient lighting, internal curtains were opened less frequently (p = 0.047). The analysis of health professionals' perceptions of physical factors demonstrated that physicians more frequently perceive the physical risk of temperature and humidity (p = 0.044). The higher the number of nurses (p = 0.004) and oral health technicians in the PHC facilities (p = 0.031), the greater the general percentage of adequacy of monitored physical parameters. It was also confirmed that the higher the perception of moderate or severe physical risk among health professionals, the lower the general percentage of the adequacy of the physical parameters of the work environment of the PHC facilities evaluated (rs = -0.450, p = 0.031). This study's evidence contributes to a better understanding of physical conditions and future occupational interventions to ensure the comfort, safety, and well-being of PHC workers.

RESUMO

This study was carried out in the district of Taquaral de Minas, in the municipality of Itinga, located in Jequitinhonha Valley, state of Minas Gerais, which is considered one of the largest yolk-producing regions in Brazil. Miners in gem extraction areas are prone to severe oxidative damage due to their increased exposure to toxic metals, as well as chemical, physical, and biological agents, resulting in diseases such as silicosis. Thus, this work aimed to evaluate occupational exposure in prospectors through biomonitoring techniques using a variety of biomarkers for oxidative stress, genotoxicity, and mutagenicity. Twenty-two miners and seventeen workers who were not occupationally exposed were recruited, totaling thirty-nine participants. The study was approved by the Research Ethics Committee of the Federal University of the Jequitinhonha and Mucuri Valleys. In this study, the levels of total peroxides, catalase activity, and microelements in plasma were evaluated. Additionally, environmental analysis was carried out through the Ames and Allium cepa tests. The results of the lipoperoxidation assessment were significant, with increased frequencies in exposed individuals compared to controls (p < 0.05), as determined by the Mann-Whitney test. Micronutrients in the blood showed lower concentrations in the group exposed to Fe and Se than in individuals not exposed to these elements. The results of the Ames test and Allium cepa test were statistically significant compared to the controls (p < 0.05), as determined by the Mann-Whitney test for genotoxicity and cytotoxicity. Thus, the results of the present study indicate possible environmental contamination and a potential risk to the health of miners, which suggests that further studies are important in the region.

RESUMO

Occupational exposure to toxic elements can adversely affect health. The current study evaluated blood concentrations of potentially toxic elements (PTE) including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, and Zn in formal and informal workers. Additionally, the study investigated the associations between blood PTE concentrations and reported health outcomes in the study population. The exposed group included women engaged in informal jewelry welding within their homes in Limeira, São Paulo state, Brazil (n = 36) and men who worked at a steel company in Volta Redonda, Rio de Janeiro state, Brazil (n = 22). The control group comprised residents of the same neighborhoods as the workers but without occupational exposure to chemicals (n = 28 in Limeira; n = 27 in Volta Redonda). Triple Quadrupole Inductively Coupled Plasma Mass Spectrometry (TQ ICP-MS) was used to determine PTE concentrations in blood samples. Glycemia, insulin, and lipid profile tests were performed. All participants completed questionnaires on household risk and reported morbidity. The blood concentrations of Cd, As, and Pb, as well as glycemia, were higher in informal workers than in control subjects. No significant differences were observed between formal workers and control subjects. A robust Poisson regression model, adjusted for variables suggested by a Directed Acyclic Graph, disclosed associations of blood lead and arsenic concentrations with the prevalence of neurological manifestations in Limeira. Blood lead levels > 2.6 µg dL-1 were associated with 2.3 times the prevalence of self-reported neurological manifestations (95 % CI: 1.17-4.58; p = 0.02) than lower blood lead concentrations. Furthermore, a positive association between blood cadmium concentrations and glycemia was observed. Informal occupational exposure to these elements may indicate an increased risk of developing diseases. Monitoring exposure and implementing interventions to reduce PTE exposure in the work environment represent significant steps toward prevention.

RESUMO

OBJECTIVE: The aim of this study was to analyse the attributable risk of mortality and DALYs (Disability Adjusted Life Years) due to occupational carcinogens for lung cancer between 1990 and 2019 in Brazil and federation units, as well as its relationship with the Socio-demographic Index (SDI). STUDY DESIGN: Epidemiological study. METHODS: This is an epidemiological study that used GBD 2019 (Global Burden of Disease Study) estimates of lung cancer mortality rates and DALYs attributable to occupational carcinogens. The relationship between these rates and SDI was assessed using panel data analysis. RESULTS: In Brazil, occupational exposure to asbestos, silica and diesel vapours accounted for more than 85.00% of lung cancer deaths and DALYs attributable to occupational carcinogens in both sexes between 1990 and 2019. An increase in both rates was observed in women for almost all the occupational carcinogens assessed, especially in the North and Northeast regions of the country, with diesel vapours standing out the most. CONCLUSIONS: The present study highlighted the urge to characterise exposure to occupational risks for lung cancer, especially for the female population in the North and Northeast regions of Brazil.

RESUMO

The ability of organophosphate pesticides to disturb immune function has been demonstrated by in vivo and in vitro studies, but evidence of such effects on humans remains scarce. To assess the association between organophosphate pesticides exposure and cytokine levels in Mexican flower workers, a cross-sectional study was carried out. A questionnaire was provided to 121 male flower workers, and urine and blood samples were collected. Using gas chromatography, urinary concentrations of dialkylphosphate metabolites were determined. The serum cytokine levels, IL-4, IL-5, IL-6, IL-8, and IL-10, were measured using multiplex analysis, and levels of INF-γ and TNF-α by ELISA. We found that a higher dialkylphosphate concentration decreased the pro-inflammatory cytokines INF-γ (ß = -0.63; 95 % CI: -1.22, -0.05), TNF-α (ß= -1.18; 95 % CI: -2.38, 0.02), and IL-6 (ß= -0.59; 95 % CI: -1.29, 0.12), and increased IL-10 (ß=0.56; 95 % CI: 0.02, 1.09), the main anti-inflammatory cytokine, suggesting an imbalance of the immune response in flower workers.

RESUMO

This document presents the ergonomic assessments carried out by Spanish surgeons on the materials used within an operating room. With the objective of disseminating and raising awareness of the importance of ergonomics, this working group has compiled information from a previously conducted survey on musculoskeletal disorders associated with surgical work from the year 2022, obtaining feedback from 131 surgeons from 17 distinct specialties. A noteworthy 80.2 % of surveyed surgeons reported having experienced forced postures during surgery, and 96.9 % believe that their physical discomfort is a result of the posture adopted during operations. Such postures can result in the development of pathologies and may have a direct impact on work performance and even in extreme cases, it can lead to sick leave or early retirement. By providing their insights on electronic devices, surgical furniture, and instrumentation, surgeons can help identify areas for improvement in the practice of their profession.

RESUMO

BACKGROUND: Intensive care physiotherapists are exposed to situations that may cause physical and mental overload, which can lead to the onset of work-related musculoskeletal complaints. OBJECTIVE: The objective was to analyze these complaints and to identify activities causing greater overload, factors associated with complaints, and management and prevention strategies. METHODS: Cross-sectional study. Data were collected from 125 physiotherapists in the Intensive Care units (ICU) of a tertiary hospital. The questionnaire used was formulated from questionnaires validated in the literature such as Nordic Questionnaire and Bork Questionnaire. Chi-square test was performed to compare the groups with and without complaints. Logistic regression was used to assess the association effects of the variables on the presence of complaints. RESULTS: Of those interviewed, 76% had a work-related complaint in the last year, with the "lower back" being the most affected region. Eighty percent had complaints for more than one site. "Transfer" was considered the activity causing the greatest overload. Female sex (p = 0.023), lack of physical activity (p = 0.028), inadequate ventilation (p = 0.001) and inadequate furniture (p = 0.006) showed a statistically significant association effect with the presence of complaints. Inadequate ventilation (p = 0.003) and female sex (p = 0.004) influenced the number of affected areas. Physical activity was considered the main strategy for prevention. CONCLUSION: Musculoskeletal complaints accounted for a high percentage of the analyzed sample, mainly in the lower back. The extent of complaints suggests that strategies should be developed and changes in work dynamics should be carried out.

RESUMO

INTRODUCTION: Combat readiness assessments through simulated tasks (STs) have been developed for the Brazilian Air Force (BAF) to establish physical employment standards. Previous research has established BAF critical combat tasks with STs developed based on the physical demands of these tasks. Before implementing these STs, the standards required of BAF personnel must be established. The aim of this study was to determine the cut-off scores for five previously established STs. METHODS: Eighty-eight cadets attended three different testing batteries in order to complete the five STs, being: Battery 1 (foot march), Battery 2 (plane crash on water and water survival skills) and Battery 3 (plane crash on land, obstacle course) with their times recorded. Cut-off scores were set at the 85th percentile of the data distribution with these values and then analysed by four subject matter experts (SMEs) using subjective criteria through criterion analysis. RESULTS: All 88 cadets were submitted to the five assessments. After analysing the performance results on the STs, the SMEs discussed and agreed on the following cut-off scores: obstacle course (3:21 min:s), foot march (31:00 min:s), plane crash on land (1:25 min:s), plane crash on water (1:12 min:s) and water survival skills (4:03 min:s). CONCLUSION: The outcomes of this research allow for the five STs to be implemented in BAF cadets and qualified BAF personnel with the established cut-off scores used to monitor the operational capability of these personnel (be it for cadet training outcomes or unit preparedness assessments) and to guide conditioning practices if personnel are below standards.

RESUMO

Background: This study aimed to analyze the trend of occupational noise-induced hearing loss (ONIHL) in Brazilian workers at a metallurgical plant with a hearing conservation program (HCP), which has been addressed in a previous study. Methods: All 152 workers in this time series (20032018) participated in the HCP and used personal protective equipment. All annual audiometry records in the company's software were collected from the electronic database. The trend of ONIHL was analyzed with the joinpoint regression model. The hearing thresholds of ONIHL cases at the end of the series were compared with those found in a national reference study. Results: The binaural mean hearing thresholds at 3, 4, and 6 kHz at the end of the series were higher for ages ≥50 years, exposures ≥85 dB (A), time since admission >20 years, and maintenance workers. Significance was found only in the group divided by age. There was an increasing time trend of ONIHL, though with a low percentage variation for the period (AAPC = 3.5%; p = 0.01). Hearing thresholds in this study differed from the reference one. Conclusion: Despite the unmet expectation of a stationary trend in the study period, the time pace of ONIHL evolution did not follow what was expected for a population exposed to noise. These findings signal to the scientific community and public authorities that good ONIHL control is possible when HCP is well implemented.
