ABSTRACT
ABSTRACT Background: The number of tuberculosis (TB) cases in prisons is higher than that in the general population and has been reported as the most common cause of death in prisons. This study evaluated the delay in the diagnosis and treatment of TB in Brazilian prisons. Methods: A retrospective cohort study was conducted between 2007 and 2015 using data from the five largest male prisons in Mato Grosso do Sul, Brazil. TB case data was collected from the National Database of Notifiable Diseases (SINAN), GAL-LACEN, and prison medical records. The following variables were recorded: prison, year of diagnosis, age, race, education, HIV status, smoking status, comorbidities, number of symptoms, percentage of cures, delay in diagnosis, patient delay, provider delay, laboratory delay, and delay in treatment. Descriptive statistics were used for the variables of interest. Results: A total of 362 pulmonary TB cases were identified. The average time between the first symptom and reporting of data was 94 days. The mean time between symptom onset and laboratory diagnosis was 91 days. The average time from symptom onset to first consultation was 80 days. The time between diagnosis and treatment initiation was 5 days. Conclusions: Delays were significant between reporting of the first symptoms and diagnosis and significantly smaller from the time between notification and start of treatment. Control strategies should be implemented to diagnose cases through active screening, to avoid delays in diagnosis and treatment, and to reduce TB transmission.
ABSTRACT
ABSTRACT Background: Tuberculosis is a worldwide public health problem and is more prevalent in specific populations, such as prisoners. The aim of this study was to analyze the epidemiological and operational indicators of tuberculosis in prisoners in a southern region of Brazil. Methods: This was a descriptive, observational study, utilizing secondary data from the Notifiable Diseases Information System on tuberculosis cases diagnosed in prisoners in the state of Rio Grande do Sul, southern Brazil, from 2014 to 2018. Prisoner data used to calculate incidence were extracted from reports by the National Penitentiary Department. Results: From 2014 to 2018, 3,557 tuberculosis cases were reported in Rio Grande do Sul prisoners. The incidence rate of tuberculosis in prisoners was 1,235/100,000 individuals in 2014 and 1,430/100,000 individuals in 2018. The proportion of new TB cases tested for HIV was high, 83.4% in this period; among those tested, 12.9% were HIV coinfected. The proportion of new cases of pulmonary tuberculosis confirmed by laboratory criteria was 52.6% in this period. In total, 18.4% of new pulmonary tuberculosis cases were initiated on directly observed treatment in this period, and 36.4% of contacts of new cases of pulmonary tuberculosis with laboratory confirmation were examined. Among retreatment pulmonary tuberculosis cases, 82.4% were laboratory-confirmed. Conclusions: Tuberculosis incidence is increasing on a per-capita and absolute basis in Rio Grande do Sul. Laboratory confirmation, HIV testing, directly observed treatment, and contact investigation rates were all low, indicating the need to improve medical and public health measures for tuberculosis control in prisons.
ABSTRACT
ABSTRACT OBJECTIVE To estimate age and sex-specific suicide rates, compare suicide rates between indigenous communities, and quantify the frequency of intrafamilial suicide clustering. METHODS We performed a retrospective cohort study involving 14,666 indigenous individuals in reservations in Dourados, state of Mato Grosso do Sul, Brazil, from 2003 through 2013 using national and local census. RESULTS The overall suicide rate was 73.4 per 100,000 person-years. Adolescent males aged 15-19 and girls aged 10-14 had the highest rates for each sex at 289.3 (95%CI 187.5-391.2) and 85.3 (95%CI 34.9-135.7), respectively. Comparing the largest reservations, Bororo had a higher suicide rate than Jaguapiru (RR = 4.83, 95%CI 2.85-8.16) and had significantly lower socioeconomic indicators including income and access to electricity. Nine of 19 suicides among children under 15 occurred in household clusters. Compared with adult suicides, a greater proportion of child (OR = 5.12, 95%CI 1.89-13.86, p = 0.001) and adolescent (OR = 3.48, 95%CI 1.29-9.44, p = 0.017) suicides occurred within household clusters. CONCLUSIONS High rates of suicide occur among children and adolescents in these indigenous reservations, particularly in poor communities. Nearly half of child suicides occur within household clusters. These findings underscore the need for broad public health interventions and focused mental health interventions in households following a suicide.

INTRODUÇÃO: Estudos anteriores relataram maior prevalência de Tuberculose e HIV entre os prisioneiros do que na população geral no Brasil, mas existem dados limitados disponíveis para facilitar o desenvolvimento de intervenções efetivas neste cenário de alta transmissão. O objetivo deste estudo foi avaliar a prevalência e os fatores de risco associados à Tuberculose e ao HIV. METODOLOGIA: Realizado questionário para a amostra de detentos de 12 prisões em Mato Grosso do Sul (Brasil), prova tuberculínica, coletado sangue para teste de HIVe duas amostras de escarro para baciloscopia e cultura de participantes que relataram tosse de qualquer duração, de Janeiro a Dezembro de2013. RESUILTADOS: Foram recrutados 3.380 detentos, dos quais 2.861(84,6%) eram homens de 8 prisões e 519 (15,4%) eram mulheres de4 prisões. Entre os 1.020 (30%) indivíduos que relataram tosse, 691(68%) coletaram escarro e foram identificados 31 casos de tuberculose ativa, com uma prevalência de 917 por 100.000 detentos. A prevalência de tuberculose latente foi de 22,5% e 11,7% para homens e mulheres,respectivamente. Dos participantes, 55 (1,63%) são soropositivos: 45(1,58%) homens e 10 mulheres (1,93%). CONCLUSÕES: Observou-se que a prevalência de tuberculose ativa e HIV são mais elevadas entre detentos do que na população geral, o que indica um alto risco de infecção e transmissão dentro dessas configurações. Para melhorar o controle da tuberculose nas prisões é necessária a detecção de casos de TB ativa em presídios através da triagem frequente e detecção de casos passiva e ativa.
BACKGROUND: Prior studies have reported higher Tuberculosis and HIVprevalence among prisoners than the general population in Brazil, yet there are limited data available to facilitate the development of effectiveinterventions in this high-transmission setting. The aim of this study wasto evaluate the prevalence and risk factors associated with TB and HIV. METHODS: We administered a questionnaire and tuberculin skin test (TST)to a population-based sample of inmates from 12 prisons in Mato Grasso do Sul (Brazil) and collected sera for HIV testing and two sputum samplesfor smear microscopy and culture from participants reporting a cough ofany duration, from January to December 2013. RESULTS: We recruited 3,380inmates, of which 2,861 (84.6%) were males from 8 prisons, and 519(15.4%) were females from 4 prisons. Among the 1,020 (30%) subjectswho reported a cough, we obtained sputum from 691 (68%) and identified31 cases of active TB for a prevalence of 917 per 100,000 prisoners. The prevalences of LTBI were 22.5% and 11.7% for male and female prisoners, respectively. Of these participants, 55 (1.63%) tested HIV-positive: 45(1.58%) men and 10 women (1.93%). It is observed that the prevalence ofTB and HIV are higher in prisons than in urban populations, indicating ahigh risk of infection and transmission within these settings. CONCLUSIONS: It is observed that the prevalence of Tuberculose and HIV are higher inprisons than in urban populations, indicating a high risk of infection andtransmission within these settings. For enhancing TB control in prisons is necessary case detection for active TB in prison facilities through frequent screening and passive and active case-finding of inmates.
