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 assess differences in the sputum microbiota of community-acquired pneumonia (CAP) patients with either COPD or asthma, specifically focusing on a patient population in Turkey.

Methods: This retrospective study included hospitalized patients > 18 years of age with a diagnosis of pneumonia between January of 2021 and January of 2023. Participants were recruited from two hospitals, and three patient groups were considered: CAP patients with asthma, CAP patients with COPD, and CAP patients without COPD or asthma.

Results: A total of 246 patients with CAP were included in the study, 184 (74.8%) and 62 (25.2%) being males and females, with a mean age of 66 ± 14 years. Among the participants, 52.9% had COPD, 14.2% had asthma, and 32.9% had CAP but no COPD or asthma. Upon analysis of sputum cultures, positive sputum culture growth was observed in 52.9% of patients. The most commonly isolated microorganisms were Pseudomonas aeruginosa (n = 40), Acinetobacter baumannii (n = 20), Klebsiella pneumoniae (n = 16), and Moraxella catarrhalis (n = 8). CAP patients with COPD were more likely to have a positive sputum culture (p = 0.038), a history of antibiotic use within the past three months (p = 0.03), utilization of long-term home oxygen therapy (p < 0.001), and use of noninvasive ventilation (p = 0.001) when compared with the other patient groups. Additionally, CAP patients with COPD had a higher CURB-65 score when compared with CAP patients with asthma (p = 0.004).

Conclusions: This study demonstrates that CAP patients with COPD tend to have more severe presentations, while CAP patients with asthma show varied microbial profiles, underscoring the need for patient-specific management strategies in CAP.

Objective: To evaluate cognitive learning, ability to perform and interpret lung ultrasound exams, and self-perception of learning among medical students after a short pedagogical intervention at a medical school in Brazil.

Methods: An experimental pilot study was conducted with medical students at different stages of their education (basic cycle, clinical cycle, and medical internship). The participants underwent a cognitive test before and after the intervention, a practical test, a test to recognize lung ultrasound pathologies, and a qualitative evaluation test at the end of the intervention. Statistical analysis was performed using a significance level of p < 0.05.

Results: A total of 42 students were included in the study, with a median age of 23 years and a predominance of males. The mean score of the pre-intervention cognitive test was 2.97 ± 0.87, and that of the post-intervention test was 6.57 ± 1.41, showing significant improvement (p < 0.001). The score of the practical test and that of the recognition of pathologies test also showed significant improvement after the intervention. There was no significant difference in execution time between the groups. Students in the clinical cycle had a better self-perception of learning.

Conclusions: Theoretical teaching and practical training of lung ultrasound in a short pedagogical intervention can improve cognitive performance, practical skills, and interpretation of the exam. The level of learning achievement was higher among more advanced students in medical education. Additionally, the students in the clinical cycle had a better perception of their learning.

Objective: To evaluate symptoms, lung function, and quality of life of a cohort of patients hospitalized for severe COVID-19 12 months after hospital admission.

Methods: This was a cross-sectional study. We included severe COVID-19 survivors hospitalized in one of three tertiary referral hospitals for COVID-19 in the city of Belo Horizonte, Brazil. Participants were submitted to lung function and six-minute walk tests and completed the EQ-5D-3L questionnaire.

Results: The whole sample comprised 189 COVID-19 survivors (mean age = 59.6 ± 13.4 years) who had been admitted to a ward only (n = 96; 50.8%) or to an ICU (n = 93; 49.2%). At 12 months of follow-up, 43% of patients presented with dyspnea, 27% of whom had a restrictive ventilatory disorder and 18% of whom presented with impaired DLCO. There were no significant differences in FVC, FEV1, and TLC between the survivors with or without dyspnea. However, those who still had dyspnea had significantly more impaired DLCO (14.9% vs. 22.4%; p < 0.020) and poorer quality of life.

Conclusions: After one year, survivors of severe COVID-19 in a middle-income country still present with high symptom burden, restrictive ventilatory changes, and loss of quality of life. Ongoing follow-up is needed to characterize long COVID-19 and identify strategies to mitigate its consequences.

Objective: To analyze the number of hospitalizations, the length of hospital stay, and mortality due to asthma, as well as the costs to the Unified Health Care System in Brazil between 2008 and 2021.

Methods: This was a cross-sectional epidemiological study using data from the Information Technology Department of the Brazilian Unified Health Care System. Proportional hospitalization and death rates were estimated per 100,000 population by age, microregion, and year.

Results: The number of hospitalizations and deaths due to asthma decreased from 2008 to 2021 (205,392 vs. 55,009 and 822 vs. 327, respectively). In addition, a between-sex difference was observed in asthma-related hospitalizations in 2008, and more men were hospitalized in 2021 (51.8%). Asthma mortality rates were similar for both sexes (50.0% each) in 2008, and a slight increase was observed in women's deaths in 2021 (52.9%). Even so, approximately one death/day and more than 55,000 hospitalizations were observed yearly, with a mean length of hospital stay of three days. Additionally, the Southeast region allocated more financial resources to asthma-related hospitalizations.

Conclusions: Our results showed that the number of deaths and hospitalizations due to asthma substantially declined during the study period.
