Objective: To evaluate the evolution of tuberculosis-related mortality, as well as gender-related and age-related tendencies, in the city of Fortaleza, Brazil. Methods: A descriptive study, based on secondary data, was conducted. All deaths from tuberculosis occurring among residents of Fortaleza in the 1980-2001 period and reported to the Ministry of Health via the Mortality Database were included. The evolution of tuberculosis-related mortality was compared with that of overall mortality and with that of mortality from all infectious diseases. The tendencies of the coefficients of overall mortality and of tuberculosis-related mortality, adjusted and unadjusted for age and gender, were calculated for the study period. Results: The coefficients of overall mortality and of tuberculosis-related mortality presented decreasing tendencies. The coefficient of tuberculosis-related mortality presented a decreasing tendency in individuals = 19 years of age (y = -0.0906x + 2.5133), from 20 to 59 years of age (y = -0.414x + 12.29) and 60 years of age (y = -1.2494x + 40.289), as well as in males (y = -0.3175x + 10.971) and females (y = -0.1933x + 6.8051). Conclusion: Despite displaying a decreasing tendency, the coefficient of tuberculosis-related mortality remains high.

Objective: To characterize deaths from pulmonary tuberculosis, according to sociodemographic and operational variables, in the city of São Luís, Brazil, and to describe their spatial distribution. Methods: This was an exploratory ecological study based on secondary data from death certificates, obtained from the Brazilian Mortality Database, related to deaths from pulmonary tuberculosis. We included all deaths attributed to pulmonary tuberculosis that occurred in the urban area of São Luís between 2008 and 2012. We performed univariate and bivariate analyses of the sociodemographic and operational variables of the deaths investigated, as well as evaluating the spatial distribution of the events by kernel density estimation. Results: During the study period, there were 193 deaths from pulmonary tuberculosis in São Luís. The median age of the affected individuals was 52 years. Of the 193 individuals who died, 142 (73.60%) were male, 133 (68.91%) were Mulatto, 102 (53.13%) were single, and 64 (33.16%) had completed middle school. There was a significant positive association between not having received medical care prior to death and an autopsy having been performed (p = 0.001). A thematic map by density of points showed that the spatial distribution of those deaths was heterogeneous and that the density was as high as 8.12 deaths/km2. Conclusions: The sociodemographic and operational characteristics of the deaths from pulmonary tuberculosis evaluated in this study, as well as the identification of priority areas for control and surveillance of the disease, could promote public health policies aimed at reducing health inequities, allowing the optimization of resources, as well as informing decisions regarding the selection of strategies and specific interventions targeting the most vulnerable populations.

Objective: To evaluate the appropriateness of the use of auscultation terminology in Brazilian respiratory disease-related medical journals published between January of 1980 and December of 2003. Methods: A descriptive study was conducted, evaluating three medical journals: the Jornal de Pneumologia (Journal of Pulmonology), Jornal de Pediatria (Journal of Pediatrics) and Revista Brasileira de Medicina (Brazilian Journal of Medicine). Original articles and case reports about respiratory diseases were selected, and auscultation terminology was extracted from these articles. The appropriateness of terms used to describe adventitious sounds was assessed. Results: We found that the inappropriate use of terms was more frequent when intermittent sounds were described than when continuous sounds were described (87.7% versus 44.0%; p = 0.0000). No significant difference was observed between the inappropriate use of terms by pulmonologists and that observed for other specialists (56.5% versus 62.0%; p = 0.26). In addition, there were no significant differences among the various regions of the country or between the periods prior to and after the dissemination of international nomenclature. Conclusion: Inappropriate use of pulmonary auscultation terms describing adventitious sounds remains common and widespread in Brazilian medical publications.

Objective: To identify factors associated with death from TB, evaluating TB cases reported for 2001 in the city of São Paulo (specifically in the neighborhoods of Cidade Tiradentes, Guaianazes, Itaquera and São Mateus) and comparing those evolving to death with those evolving to cure. Methods: We investigated all deaths in which TB was given as the principal cause (n = 48), analyzing medical charts and conducting home visits to interview the caregiver(s). In parallel, we investigated 96 TB cases in which the patient had been discharged after a cure had been achieved. Patients with HIV were excluded from both groups. Results: There were no differences between the two groups in terms of the clinical form of tuberculosis, laboratory test confirmation of the diagnosis and type of treatment. Death from TB was found to be associated, in a statistically significant manner, with being male, being over 50 years of age, having had less than 3 years of schooling, suffering from alcoholism and being unemployed. The logistic regression showed that the variables presenting the strongest associations with death from TB were suffering from alcoholism and being over 50, whereas being a new treatment and being employed were found to be protective. The combination of suffering from alcoholism, being unemployed and being over 50 increased the chance of evolving to death by 25 times (95%CI: 6.43-97.20). Conclusion: Ongoing education of health professionals, prompt epidemiological interventions and efficient patient referral systems could improve the indices related to this disease.

Objective: To analyze the temporal trend of tuberculosis cure indicators in Brazil. Methods: An ecological time-series study using administrative data of reported cases of the disease nationwide between 2001 and 2022. We estimated cure indicators for each federative unit (FU) considering individuals with pulmonary tuberculosis, tuberculosis-HIV coinfection, and those in tuberculosis retreatment. We used regression models using joinpoint regression for trend analysis, reporting the annual percentage change and the average annual percentage change. Results: For the three groups analyzed, we observed heterogeneity in the annual percentage change in the Brazilian FUs, with a predominance of significantly decreasing trends in the cure indicator in most FUs, especially at the end of the time series. When considering national indicators, an average annual percentage change of -0.97% (95% CI: -1.23 to -0.74) was identified for the cure of people with pulmonary tuberculosis, of -1.11% (95% CI: -1.42 to -0.85) for the cure of people with tuberculosis-HIV coinfection, and of -1.44% (95% CI: -1.62 to -1.31) for the cure of people in tuberculosis retreatment. Conclusions: The decreasing trends of cure indicators in Brazil are concerning and underscore a warning to public authorities, as it points to the possible occurrence of other treatment outcomes, such as treatment discontinuity and death. This finding contradicts current public health care policies and requires urgent strategies aiming to promote follow-up of patients during tuberculosis treatment in Brazil.

Objective: To determine the prevalence of asthma among adolescents (13-14 years of age) in the city of Fortaleza, Brazil. Methods: This was a cross-sectional study involving 3,015 adolescents at public and private schools between 2006 and 2007. The participants completed the International Study of Asthma and Allergies in Childhood questionnaire. Results: The prevalences of "wheezing ever", "wheezing within the last 12 months" (active asthma) and "asthma ever" (physician-diagnosed asthma) were 44.1%, 22.6% and 11.6%, respectively. The prevalences of "wheezing ever" (p = 0.001), "1-3 wheezing attacks within the last 12 months" (p = 0.001), active asthma (p = 0.002), "sleep disturbed due to wheezing less than one night per week" (p < 0.001) and "dry cough at night" (p < 0.001) were higher among girls. Private school students presented higher prevalences of "wheezing ever", active asthma, "1-3 wheezing attacks within the last 12 months", "4-12 wheezing attacks within the last 12 months" and physician-diagnosed asthma (p < 0.001 for all), as well as of "exercise-induced wheezing" (p = 0.032). Conclusions: The prevalence of asthma and asthma-related symptoms in students aged 13-14 years in the city of Fortaleza, Brazil, was high, predominantly among girls and private school students. The difference between the prevalence of physician-diagnosed asthma and that of active asthma suggests that asthma was underdiagnosed in the population studied.

Objective: To describe the prevalences of asthma and rhinitis in adolescents (13-14 years of age) in the city of Fortaleza, Brazil, in 2010, comparing the results with those obtained in a prevalence survey conducted in 2006-2007. Methods: This was a cross-sectional study involving probabilistic samples of 3,015 and 3,020 adolescents in surveys conducted in 2006-2007 and 2010, respectively. The International Study of Asthma and Allergies in Childhood protocol was used on both occasions. Results: Comparing the two periods, there were no significant differences regarding cumulative wheezing, active asthma, four or more wheezing attacks within the last year, sleep disturbed by wheezing more than one night per week, and speech-limiting wheezing. The prevalences of exercise-induced wheezing, dry cough at night, and physician-diagnosed asthma were significantly higher in 2010 than in the 2006-2007 period (p < 0.01 for all). The prevalence of physician-diagnosed rhinitis was significantly lower in 2010 (p = 0.01), whereas there were no significant differences between the two periods regarding cumulative rhinitis, current rhinitis, and rhinoconjunctivitis. In both periods, dry cough at night, current rhinitis, and rhinoconjunctivitis were significantly more prevalent in females than in males (p < 0.01 for all). Also in both periods, active asthma, current rhinitis, and rhinoconjunctivitis were more prevalent in private school students than in public school students (p < 0.01 for all). Conclusions: Our data show that the prevalences of asthma and rhinitis symptoms remain high among 13- and 14-year-olds in Fortaleza, predominantly among females and private school students.

Objective: To evaluate deaths attributed to multiple causes in which tuberculosis was one of the causes listed. Methods: All deaths among residents of the state of Rio de Janeiro, Brazil, occurring between 1999 and 2001 and for which the death certificate mentioned tuberculosis, were investigated. The World Health Organization guidelines were used in characterizing the underlying and associated (non-underlying) causes of death. Results: In deaths from tuberculosis, conditions related to its natural history were the principal associated causes, together with alcoholism and diabetes. In approximately three-fifths of all deaths for which tuberculosis was listed as an associated cause, the underlying cause of death was acquired immunodeficiency syndrome. High proportion of ill-defined causes of death, low values found for the number of causes informed per death certificate and for TB as an associated cause point towards a certain degree of underestimation of the actual number of TB-related deaths in Rio de Janeiro State. Conclusion: The study shows that the rates of tuberculosis-related mortality in the state of Rio de Janeiro, calculated based on the number of times tuberculosis was listed as a cause of death (underlying or associated), are the highest in the country. Epidemiological studies of mortality are recommended as a means of guiding the activities of the tuberculosis control program.

The objective of this study was to determine the prevalence of HIV infection among individuals ≥ 15 years of age with a confirmed diagnosis of tuberculosis and treated at family health care clinics in the city of Fortaleza, Brazil. We evaluated a random sample of 110 patients with tuberculosis, treated at a total of 26 family health care clinics between January and May of 2009. All of the participants completed a questionnaire regarding sociodemographic and clinical data, and all underwent HIV testing. In this sample, the prevalence of tuberculosis/HIV co-infection was 3.6% (95% CI: 0.2-7.0).
