Temporal Pattern and Spatial Distribution of Tuberculosis Prevalence Associated with Multimorbidity in Brazil

BACKGROUND

Four main chronic conditions may be involved in the tuberculosis pathogenic process and/or clinical evolution: HIV/AIDS, diabetes mellitus, mental illness, and Chronic Obstructive Pulmonary Disease. This study aimed to determine the spatiotemporal pattern of tuberculosis (TB) associated with multimorbidity in Brazil.

METHODS

Ecological study use data from the Notifiable Diseases Information System (SINAN), collected from the electronic portal of the Department of Informatics of the SUS (DATASUS). These data included TB cases that were reported between 2007 and 2021 and were associated with two or more chronic clinical health conditions (multimorbidity).

RESULTS

A total of 7,795 cases of TB associated with multimorbidity were recorded, with an average growth trend of 4.6% per year (95% Confidence Interval (CI): 3.3-5.9; p<0.001) and higher growth in the first temporal segment (2007 to 2011) (8.9%; 95%CI: 4.2-13.9; p=0.002). The spatial analysis, after Bayesian smoothing, highlighted the main municipalities states of the study, namely: São Paulo (19.8%; n = 297), Porto Alegre (23.6%; n = 354), and Rio de Janeiro (44.8%; n = 672). The proportion of extremely poor (β=-0.002), the bolsa família program (β=0.002), the average per-person income (β=0.001), and the percentage of the population living in households with a density of more than 2 people per bedroom (β=0.001) were related to chronic health conditions.

CONCLUSIONS

These findings will stimulate public action to manage this situation. However, as this is still a recent topic in the literature, we encourage the development of studies on the synergistic characteristics of TB and other clinical conditions.

Challenges faced by health workers in the use of the directly observed treatment (DOT) for tuberculosis

Tuberculosis is a worldwide public health problem, which, even with available treatment, continues to cause deaths worldwide. One of the obstacles to control the disease is the multifactorial difficulty of patients to adhere to treatment, in addition to the difficulty of health workers in circumventing barriers to implement strategies such as the directly observed treatment (DOT). The aim of this study is to analyze the performance and challenges faced by health workers in the use of DOT in tuberculosis. This is a descriptive, quali-quantitative study using data from interviews with primary-care professionals working in nine municipalities of Parana State, Brazil. The professionals answered a questionnaire containing four closed questions about DOT and an open question related to their professional opinion about the strategy. Quantitative data were entered into a spreadsheet and statistically propagated. Qualitative data were treated from the transcription of statements, subsequently submitted to content analysis. Of the 387 professionals interviewed, at least 58.9% had some knowledge about DOT. Among the main challenges faced by the professionals are: lack of user commitment to treatment (48.3%), users' difficulty in attending the basic health clinics (BHC) (31.4%), professionals' difficulty to reach the place where patients are treated (8.8 %), insufficient staff / lack of human resources (4.1%) and use of illicit drugs by patients (3.9%). Blaming the user and the lack of resources are the main highlights, in addition to issues such as the professionals' lack of access and knowledge that are highlighted by the difficulty of patients to adhere to the treatment of tuberculosis according to the participants' statements. The issues were raised by health workers manifestations involving adherence to treatment according to the DOT in the studied health region. It is possible, in this context, to observe the need for improvement in the knowledge of professionals with regard to the DOT, the importance of their bond with patients and families and the recognition of the part of responsibility that belongs to the health team on guaranteeing treatment.

Current State of Diabetes Mellitus Prevalence, Awareness, Treatment, and Control in Latin America: Challenges and Innovative Solutions to Improve Health Outcomes Across the Continent

PURPOSE OF REVIEW

Latin America is the scenario of great inequalities where about 32 million human beings live with diabetes. Through this review, we aimed at describing the current state of the prevalence, awareness, treatment, and control of diabetes mellitus and completion of selected guidelines of care across Latin America and identify opportunities to advance research that promotes better health outcomes.

RECENT FINDINGS

The prevalence of diabetes mellitus has been consistently increasing across the region, with some variation: higher prevalence in Mexico, Haiti, and Puerto Rico and lower in Colombia, Ecuador, Dominican Republic, Peru, and Uruguay. Prevalence assessment methods vary, and potentially underestimating the real number of persons with diabetes. Diabetes unawareness varies widely, with up to 50% of persons with diabetes who do not know they may have the disease. Glycemic, blood pressure, and LDL-C control and completion of guidelines to prevent microvascular complications are not consistently assessed across studies, and the achievement of control goals is suboptimal. On the other hand, multiple interventions, point-of-care/rapid assessment tools, and alternative models of health care delivery have been proposed and tested throughout Latin America. The prevalence of diabetes mellitus continues to rise across Latin America, and the number of those with the disease may be underestimated. However, some local governments are embedding more comprehensive diabetes assessments in their local national surveys. Clinicians and public health advocates in the region have proposed and initiated various multi-level interventions to address this enormous challenge in the region.

[Factors associated with unsuccessful treatment of patients with drug-sensitive tuberculosis in Paraguay]

Objetivo.

Determinar los factores asociados con el tratamiento no exitoso en pacientes diagnosticados con tuberculosis (TB) sensible en Paraguay.

Métodos.

Estudio de cohorte retrospectivo, con datos recolectados del programa nacional entre enero de 2016 y marzo de 2017. Se definió tratamiento no exitoso como pacientes que se perdieron en el seguimiento, fracasaron en el tratamiento o fallecieron. Los factores asociados con tratamiento no exitoso se determinaron con regresión de Poisson; se estimó el riesgo relativo (RR) y el intervalo de confianza de 95% (IC95%) ajustados por región sanitaria.

Resultados.

Se estudiaron 3 034 casos: 2 189 (72,1%) tuvieron tratamiento exitoso (curados: 1 221 [40,2%], tratamiento completo: 968 [31,9%]) y 845 (27,9%) presentaron tratamiento no exitoso (fracaso: 40 [1,3%], pérdida de seguimiento: 466 [15,4%] y fallecidos: 339 [11,2%]). Los factores asociados a tratamiento no exitoso fueron hombres 1,28 (1,14- 1,42), indígenas 1,30 (1,09- 1,54), sin reporte de área de residencia 1,27 (1,02- 1,57), coinfección TB/VIH 1,97 (1,63- 2,38), adicción a drogas ilícitas 1,38 (1,16- 1,63), consumo de alcohol 1,25 (1,02- 1,52), ser previamente tratado 1,23 (1,10- 1,38) y sin datos de supervisión del tratamiento 4,92 (3,69- 6,56). Como factores protectores se consideran ser persona privada de libertad 0,65 (0,47- 0,89), así como la comorbilidad TB/diabetes 0,80 (0,67- 0,95).

Conclusión.

Paraguay presenta un alto porcentaje de tratamiento no exitoso en casi todo el país, sin alcanzar la meta propuesta por la Organización Mundial de la Salud. Los factores de riesgo asociados como infección por el virus de la inmunodeficiencia humana (VIH), consumo de drogas licitas e ilícitas y el ser indígena revela que es necesario revisar las estrategias dirigidas con abordaje interinstitucional.
