Sociodemographic factors associated with the success or failure of anti-tuberculosis treatment in the Chiapas Highlands, Mexico, 2019-2022.

Objective: To estimate the incidence rate of tuberculosis (TB) in the Highlands (Tsotsil-Tseltal) region of Chiapas and to analyze sociodemographic factors that might influence the success of anti-TB treatment from the period of January 2019 to June 2022.

Methods: Retrospective study in which the TB databases of the National Epidemiological Surveillance System (SINAVE) were analyzed. TB incidence rates were calculated based on the number of registered TB cases and estimated annual populations.

Conceptual and methodological aspects in the study of hospitalizations for ambulatory care sensitive conditions.

Hospitalization rates for Ambulatory Care Sensitive Conditions have been used to assess effectiveness of the first level of health care. From a critical analysis of related concepts, we discuss principles for selecting a list of codes and, taking the example of the Brazilian Family Health Program, propose a methodological pathway for identifying variables in order to inform statistical models of analysis. We argue that for the indicator to be comparable between regions, disease codes should be selected based on sensitivity and specificity principles, not on observed disease frequency.

Pulmonary tuberculosis infection among workers in the informal public transport sector in Lima, Peru.

Background: Because a strong association was observed between pulmonary tuberculosis (TB) and the use of public transport, increasing with duration of journey, a study was carried out to assess infection by Mycobacterium tuberculosis and working conditions among workers in this sector.

Methods: A cross-sectional study was conducted between June and September 2008. A total of 104 workers from two public transport minibus ('combi') cooperatives covering marginal areas of the Ate-Vitarte district in Lima were interviewed.

Risk of tuberculosis in public transport sector workers, Lima, Peru.

Setting: Delays from symptom onset to the diagnosis and treatment of smear-positive pulmonary tuberculosis (TB) produces possible new cases in persons in close contact with TB cases, especially in confined spaces such as overcrowded public transport, which puts other users and transport workers at risk.

Objective: To estimate TB incidence rates in patients of a health micro-network, and the percentage of transport sector workers among TB and multidrug-resistant TB (MDR-TB) patients.

Design: Crude and indirect standardised incidence rates of TB were calculated from an exhaustive analysis of all clinical histories of incident patients in a health micro-network between 1 January 2007 and 30 June 2008.
