This study evaluates the antimicrobial efficacy of chitosan nanoparticles (CNPs), varying in size, against clinical isolates of (MTB), , , , and , as well as the antimicrobial effects of aqueous extracts and lyophilized powders of (garlic) species. CNPs were synthesized through ionotropic gelation and characterized by Z potential, hydrodynamic diameter (dynamic light scattering, DLS), and SEM. Aqueous garlic extracts were prepared via decoction.

Mexican President Andrés Manuel López Obrador's historic election victory in 2018 marked a sharp break from past decades of neoliberal socioeconomic policies. López Obrador campaigned on the promise of deep reform, with health care high on his agenda. The public health care sector had been decimated by decades of budget cuts, eroding workers' morale and patients' confidence, and crippling all aspects of the system.

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.

This is the first report of the genetic diversity of the complex isolates found in a Mexican-Amerindian setting. In this study, we analyzed isolates collected from the Highlands region of Chiapas, Mexico, by using spoligotyping and whole-genome sequencing analyses. Seventy-three isolates were analyzed initially by spoligotyping; no new spoligotypes were identified.

This article analyzes the fulfillment of the four essential and interrelated elements of availability, accessibility, acceptability, and quality (AAAQ) presented in General Comment 14 of the United Nations Committee on Economic, Social and Cultural Rights. We examined the ways that AAAQ criteria are met in tuberculosis (TB) care by evaluating a sample of 33 primary health care units (PHCUs) in 10 municipalities of the Chiapas Highlands region of Mexico. We collected information about 56 people with TB who were treated in those PHCUs, the structural conditions of the health facilities, and data about all health care workers in the PHCUs (n=423).

Background: Rural communities in the Amazonian southern border of Ecuador have benefited from governmental social programmes over the past 9 years, which have addressed, among other things, diseases associated with poverty, such as soil transmitted helminth infections. The aim of this study was to explore the prevalence of geohelminth infection and several factors associated with it in these communities.

Methods: This was a cross sectional study in two indigenous communities of the Amazonian southern border of Ecuador.

Objective: To estimate rates of cases of respiratory symptomatic subjects and the incidence rate of pulmonary tuberculosis in two border areas of Ecuador, and contrast them with official figures.

Materials And Methods: Cross-sectional survey in the southeastern (SEBA), and the Andean southern Ecuadorian border areas (ASBA), which were conducted, respectively, in 1 598 and 2 419 persons aged over 15 years recruited over periods of three weeks. In identified respiratory symptomatic cases, a sputum sample was taken for smear testing.

Unlabelled: A growing body of literature analyzes farmer perceptions of pesticide risk, but much less attention has been given to differences in risk perception between farmers and technical experts. Furthermore, inconsistencies in knowledge have too easily been explained in terms of lack of knowledge rather than exploring the underlying reasons for particular forms of thinking about pesticide risks. By doing this, the division between expert and lay knowledge has been deepened rather than transcended.

Objective: To analyze the perceptions and interactions of the actors involved in anti-tuberculosis treatment, and to explore their influence in treatment defaulting in Los Altos region of Chiapas, Mexico.

Material And Methods: From November 2002 to August 2003, in-depth interviews were administered to patients with PTB, patients' family members, institutional physicians, community health coordinators, and traditional medicine practitioners.

Results: We found different perceptions about PTB between patients and their families and among health personnel, as well as communication barriers between actors.

We performed a cross-sectional, community-based survey, supplemented by interviews with community leaders in Chiapas, Mexico, to examine the prevalence and predictors of child malnutrition in regions affected by the Zapatista conflict. The prevalence rates of stunting, wasting, and underweight were 54.1%, 2.

The Zapatista armed conflict began in the state of Chiapas, Mexico, in 1994, and overlaps pre-existing local disputes about land, religion, and other issues. Related disruptions in access to and utilization of health services have been alleged to have compromised local health status, particularly in vulnerable subgroups such as indigenous women and infants. The study objective was to measure maternal and perinatal mortality ratios and utilization of pregnancy-related health services in the region affected by the Zapatista conflict, and to describe associations between these primary outcome measures, socioeconomic and demographic factors, and factors associated with inter-party and intra-community conflict.

Objective: To assess the prevalence of intestinal parasitic infections among children in highly deprived areas, and its possible association with demographic and socioeconomic indicators.

Material And Methods: From March to September 1998 in a convenience sample of 32 communities of the border region of Chiapas, Mexico, selected at random based on the level of poverty and distance from the community to the nearest health care unit (< 1 hour; 1 hour or more), one of every four households with children under 15 years of age was randomly selected to provide three stool samples from their children (n 1478). Bivariate and multivariate (generalized linear models for correlated binary data), analysis were performed.
