Background: Among chronic condition problems, tuberculosis still represents a serious public health problem globally., Objective: To investigate latent tuberculosis infection in patients with Crohn's disease. Retrospective, descriptive cross-sectional study of quantitative analysis., Methods: The research was conducted on diagnosed cases of Crohn's disease at the University Hospital located in a city in Northeastern Brazil. All cases of patients with Crohn's disease undergoing isoniazid or rifampicin therapy for latent tuberculosis (LTBI) were included in the study. The data obtained were subsequently subjected to statistical analysis using the Statistical Package for the Social Sciences (SPSS) program., Results: We analyzed 235 medical records, and it was observed that 56% were male, with a mean age of 42.7. Among these, 54% declared themselves as brown, 31% had completed high school, and 47% were residents of the city of Teresina. Regarding the clinical and epidemiological characteristics of the studied patients classified as having ILTB, 34% of the medical records were diagnosed by tuberculin test, 48.51% were investigated by x-ray examination, and the recent location affected the colon with 27%., Conclusion: Overall, the health profile of the participants in this study aligns with findings previously established in the literature, particularly studies conducted in other Brazilian states, as well as in other developing countries.

Objective: To analyze HIV prevalence and associated factors in inmates in a prison in a state in the Northeast region of Brazil., Method: Epidemiological, cross-sectional study carried out with prisoners. Interviews were conducted using a form and a rapid test for the diagnosis. Bivariate and multivariate hypothesis testing, with a simple logistic ratio (unadjusted odds ratio) and multiple ratio (adjusted odds ratio) were applied. Significance level was set at p≤0.05., Results: A total of 2,131 inmates participated in the study. The HIV prevalence was 1.0%. Seropositive individuals were mostly Afro-American; their marital status was predominantly single/separated/widower. The mean age was of 31.3 years, and the mean educational level was 6.29 years. There was a link between the HIV virus and the variables: selection of partners based on physical attributes and vaginal sexual intercourse., Conclusion: Tackling the HIV infection represents a major challenge for prison and sanitary authorities, considering that the issues related to the HIV context inside and outside the prison environment are interconnected and, therefore, demands coordinated action.
