Group Prenatal Care in Mexico: perspectives and experiences of health personnel

OBJETIVO: Identificar barreras y facilitadores de la implementación del modelo de Atención Prenatal en Grupo en México (APG), desde la perspectiva del personal de salud. MÉTODOS: Estudio cualitativo descriptivo en cuatro clínicas de la Secretaría de Salud en dos estados de México (Morelos e Hidalgo) de junio de 2016 a agosto de 2018. Se realizaron 11 entrevistas semi-estructuradas a prestadores de servicios de salud. Se exploraron sus percepciones y experiencias durante la implementación del modelo de APG. Se identificaron barreras y facilitadores para su adopción en dos dimensiones: a) estructurales (espacio, recursos, personal de salud, volumen de pacientes, comunidad) y b) actitudinales (motivación, liderazgo, aceptabilidad, abordaje de problemas, clima y comunicación). RESULTADOS: Las barreras más relevantes reportadas en el nivel estructural fueron la disponibilidad de espacio físico en las unidades y la sobrecarga de trabajo del personal de salud. Se identificó la dificultad para adoptar una relación menos jerárquica durante la atención a las gestantes en el nivel actitudinal. El principal facilitador a nivel actitudinal fue la aceptabilidad que los prestadores tienen del modelo. Un hallazgo específico para el contexto de la implementación en México fue la resistencia al cambio en la relación médico-paciente; resulta difícil abandonar el modelo jerárquico prevaleciente y cambiar a una relación más horizontal con las gestantes. CONCLUSIONES: El análisis de la implementación del modelo de APG en México, desde la perspectiva del personal de salud, ha evidenciado barreras y facilitadores similares a las experiencias en otros contextos. Esfuerzos futuros para la adopción del modelo deberán enfocarse en la atención oportuna de las barreras identificadas, sobre todo aquellas señaladas en la dimensión actitudinal que pueden ser modificadas a través de capacitaciones continuas al personal de salud.OBJECTIVE: Identify barriers and facilitators to implementing the Group Prenatal Care model in Mexico (GPC) from the health care personnel’s perspective. METHODS: We carried out a qualitative descriptive study in four clinics of the Ministry of Health in two states of Mexico (Morelos and Hidalgo) from June 2016 to August 2018. We conducted 11 semi-structured interviews with health care service providers, and we examined their perceptions and experiences during the implementation of the GPC model. We identified the barriers and facilitators for its adoption in two dimensions: a) structural (space, resources, health personnel, patient volume, community) and b) attitudinal (motivation, leadership, acceptability, address problems, work atmosphere and communication). RESULTS: The most relevant barriers reported at the structural level were the availability of physical space in health units and the work overload of health personnel. We identified the difficulty in adopting a less hierarchical relationship during the pregnant women’s care at the attitudinal level. The main facilitator at the attitudinal level was the acceptability that providers had of the model. One specific finding for Mexico’s implementation context was the resistance to change the doctor-patient relationship; it is difficult to abandon the prevailing hierarchical model and change to a more horizontal relationship with pregnant women. CONCLUSION: Analyzing the GPC model’s implementation in Mexico, from the health care personnel’s perspective, has revealed barriers and facilitators similar to the experiences in other contexts. Future efforts to adopt the model should focus on timely attention to identified barriers, especially those identified in the attitudinal dimension that can be modified by regular health care personnel training

Comparison of total immunoglobulin A levels in different samples in Leghorn and broiler chickens

Objective: To standardize an ELISA protocol to quantify total immunoglobulin A (IgA) from different biological samples. Methods: Two independent experiments were conducted. In Experiment 1, total IgA levels were quantified from the lachrymal fluid, tracheal swab, and cloacal swab at various time points from Days 30 to 89 in white Leghorn chickens. Experiment 2 was conducted to evaluate the effect of 50 or 500 ppb of aflatoxin B1 (AFB1) on total IgA quantified in samples from the lachrymal fluid, tracheal swab, gut content and cloacal swab in broiler chickens at 21 days of age. Results: Lachrymal fluid contained the highest level of IgA; however, the sampling procedure was time consuming and stressful to the bird, and the sample volume depends largely on the size of the chicken. Cloacal swabs also contained a high concentration of IgA; this sampling procedure was faster than lachrymal fluid sampling and was not affected by the age of the bird. Tracheal sampling was more difficult than cloacal sampling; the age of the bird limited the sampling, and the IgA concentration was the lowest detected at all sampling ages. 500 ppb of AFB1 significantly reduced total IgA concentration in the gut content compared with control or 50 ppb of AFB1 treated groups. Interestingly, a significant reduction in total IgA was also observed in those chickens that received 50 ppb of AFB1 in gut rinse when compared with cloacal swabs. Conclusions: The results of this study suggest that cloacal swab is an easy and reliable way to evaluate mucosal IgA concentration in both Leghorn and broiler chickens

Active Surveillance of Antimicrobial Resistance and Carbapenemase-Encoding Genes According to Sites of Care and Age Groups in Mexico: Results from the INVIFAR Network

We analyzed the antimicrobial resistance (AMR) data of 6519 clinical isolates of Escherichia coli (n = 3985), Klebsiella pneumoniae (n = 775), Acinetobacter baumannii (n = 163), Pseudomonas aeruginosa (n = 781), Enterococcus faecium (n = 124), and Staphylococcus aureus (n = 691) from 43 centers in Mexico. AMR assays were performed using commercial microdilution systems (37/43) and the disk diffusion susceptibility method (6/43). The presence of carbapenemase-encoding genes was assessed using PCR. Data from centers regarding site of care, patient age, and clinical specimen were collected. According to the site of care, the highest AMR was observed in E. coli, K. pneumoniae, and P. aeruginosa isolates from ICU patients. In contrast, in A. baumannii, higher AMR was observed in isolates from hospitalized non-ICU patients. According to age group, the highest AMR was observed in the ≥60 years age group for E. coli, E. faecium, and S. aureus, and in the 19–59 years age group for A. baumannii and P. aeruginosa. According to clinical specimen type, a higher AMR was observed in E. coli, K. pneumoniae, and P. aeruginosa isolates from blood specimens. The most frequently detected carbapenemase-encoding gene in E. coli was blaNDM (84%)
