Ecological association between socioeconomic, occupational and sanitation factors and the occurrence of scorpionism in Brazil, 2007-2019 / Associação ecológica entre fatores socioeconômicos, ocupacionais e de saneamento e a ocorrência de escorpionismo no Brasil, 2007-2019

Objective: To analyze the ecological association between socioeconomic, occupational, and sanitation characteristics and scorpionism in Brazil. Methods: Ecological study with data on scorpion accidents reported in the Notifiable Diseases Information System (2007-2019). Negative binomial regression was used to estimate ratios of incidence rates (RTI) and confidence intervals (95%CI). Results: In the period, 1,079,333 scorpion accidents occurred, with accumulated incidence 41.5/100,000 in habitants. In the adjusted analysis, there was an association with the municipal percentage of: women (IRR=1.65 ­ 95%CI 1.18;2.30) and men (IRR=0.90 ­ 95%CI 0.88;0.91) in civil construction, women (IRR=1.21 ­ 95%CI 1.18;1.25) and men(IRR=0.73 ­ 95%CI 0.69;0.77) in domestic service, women (IRR=1.03 ­ 95%CI 1.02;1.04) and men (IRR=0.93 ­ 95%CI 0.92;0.93) in agriculture, households with garbage collection (IRR=0.99 ­ 95%CI 0.98;0.99) and garbage in surroundings(IRR=1.02 ­ 95%CI 1.01;1.02), expectation of years of study (IRR=0.88 ­ 95%CI 0.83;0.92), and unemployment rate (IRR=1.07 ­ 95%CI 1.05;1.09). Conclusion: Scorpionism was associated with precarious infrastructure/sanitation, job offer, education and female occupation.

Objetivo: Analisar associação ecológica entre características socioeconômicas, ocupacionais e de infraestrutura/saneamento com escorpionismo no Brasil. Métodos: Estudo ecológico, com dados dos acidentes escorpiônicos notificados no Sistema deInformação de Agravos de Notificação (2007-2019). Empregou-se regressão binomial negativa para estimar razões de taxas de incidência (RTI) e intervalos de confiança(IC95%). Resultados: No período, ocorreram 1.079.333 acidentes, com incidênciaacumulada de 41,5/100 mil habitantes. Na análise ajustada, houve associação com percentual municipal de mulheres (RTI=1,65 ­ IC95% 1,18;2,30) e homens (RTI=0,90 ­IC95% 0,88;0,91) na construção civil, mulheres (RTI=1,21 ­ IC95% 1,18;1,25) e homens(RTI=0,73 ­ IC95% 0,69;0,77) no serviço doméstico, mulheres (RTI=1,03 ­ IC95% 1,02;1,04) e homens (RTI=0,93 ­ IC95% 0,92;0,93) na agropecuária, domicílios com lixo coletado (RTI=0,99 ­ IC95% 0,98;0,99) e lixo no entorno (RTI=1,02 ­ IC95% 1,01;1,02),2 expectativa de anos de estudo (RTI=0,88 ­ IC95% 0,83;0,92) e taxa de desocupação (RTI=1,07 ­ IC95% 1,05;1,09). Conclusão: O escorpionismo associou-se a precária infraestrutura/saneamento, oferta de emprego, educação e ocupação feminina.

Common Mental Disorders among Occupational Groups: Contributions of the Latent Class Model.

Background. The Self-Reporting Questionnaire (SRQ-20) is widely used for evaluating common mental disorders. However, few studies have evaluated the SRQ-20 measurements performance in occupational groups. This study aimed to describe manifestation patterns of common mental disorders symptoms among workers populations, by using latent class analysis. Methods. Data derived from 9,959 Brazilian workers, obtained from four cross-sectional studies that used similar methodology, among groups of informal workers, teachers, healthcare workers, and urban workers. Common mental disorders were measured by using SRQ-20. Latent class analysis was performed on each database separately. Results. Three classes of symptoms were confirmed in the occupational categories investigated. In all studies, class I met better criteria for suspicion of common mental disorders. Class II discriminated workers with intermediate probability of answers to the items belonging to anxiety, sadness, and energy decrease that configure common mental disorders. Class III was composed of subgroups of workers with low probability to respond positively to questions for screening common mental disorders. Conclusions. Three patterns of symptoms of common mental disorders were identified in the occupational groups investigated, ranging from distinctive features to low probabilities of occurrence. The SRQ-20 measurements showed stability in capturing nonpsychotic symptoms.

Clinical diagnosis versus autopsy

Records from 910 autopsies performed at a university hospital in Salvador, Bahia, Brazil, were examined in order to assess the accuracy of clinical diagnoses of the patients' underlying causes of death. This study found inaccurate clinical diagnoses in 31 per cent of the cases. The overall rate of diagnostic error appeared to remain fairly stable from 1970 to 1982 being highest for older patients. Thirthy-six percent of the 263 cancer deaths were incorrectly diagnosed, and a number of pathologies considered relatively easy to diagnose were not always correctly identified. Quite aside from their direct medical implications, diagnostic errors of the magnitude observed in this and other studies seriosly jeopardize the quality of vital statistics and such statistics' usefulness for improving public health
