RESUMO

BACKGROUND: Maternal and child malnutrition represents a public health problem in Mexico Primary care (PC) is responsible for introducing women and children under five to the health system, detecting diseases on time, and providing medical services, including pharmacological treatment if necessary. Providing these services with quality is essential to improve maternal and child health. This study evaluated the quality of nutritional care during preconception, pregnancy, postpartum, infancy, and preschool age at the PC health units across six Mexican states between 2020 and 2021. METHODS: We conducted a cross-sectional study with a mixed approach in units of the Secretary of Health to assess the quality of nutritional care during preconception, pregnancy, postpartum, childhood, and preschool age. The level of quality was calculated by the percentage of compliance with 16 indicators that integrated a Quality Index of Maternal and Child Nutritional Care (ICANMI, by its Spanish acronym). Compliance by indicator, by life stage, and overall was categorized using the following cut-off points: poor quality (≤ 70%), insufficient quality (71-89%), and good quality (≥ 90%). The perceptions of the barriers and facilitators that affect maternal and child nutrition were evaluated through semi-structured interviews with health professionals (HP) and users. All qualitative instruments were developed with a gender and intercultural perspective. RESULTS: Considering the whole sample studied, maternal and child nutritional care quality during the five life stages evaluated was bad (compliance: ≤12%), reflected in the ICANMI, which had a compliance of 8.3%. Principal barriers identified to providing high-quality nutritional care were the lack of knowledge and training of health professionals, shortages of equipment, medicine, personnel, and materials, the disappearance of the social cash transfer program Prospera, the absence of local indigenous language translators to support communication between doctor and patient, and the persistence of machismo and other practices of control over women. CONCLUSIONS: These findings underscore the need for initiatives to improve the quality of nutritional care in PC facilities across Chihuahua, State of Mexico, Veracruz, Oaxaca, Chiapas, and Yucatan. It is necessary for government and health authorities, along with various stakeholders, to collaboratively devise, implement, and assess intercultural and gender-oriented policies and programs geared towards ensuring the health infrastructure and enhancing the training of health professionals to diagnose and treat the prevalence and occurrence of diverse forms of malnutrition in both maternal and child populations.

RESUMEN: ANTECEDENTES: La mala nutrición materno-infantil (MMI) representa un problema de salud pública en México. El primer nivel tiene la respondabilidad de introducir a mujeres y niños menores de 5 años al sistema de salud, detectar oportunamente las enfermedades y brindar servicios médicos incluido el farmacológico de ser necesario. Prestar estos servicios con calidad resulta elemental para mejorar la salud de la población materno-infantil. El objetivo de este estudio fue evaluar la calidad de la atención nutricional durante las etapas de preconcepción, embarazo, posparto, infancia y edad preescolar en centros de salud de seis estados de México entre 2020 y 2021. MéTODOS: Se realizó un estudio transversal con metodología mixta en 95 centros de salud la Secretaría de Salud de México para evaluar la calidad de la atención nutricional durante la preconcepción, el embarazo, el posparto, la infancia y la etapa preescolar. El nivel de calidad se calculó mediante el porcentaje de cumplimiento de 16 indicadores que a su vez integraron un Índice de Calidad de la Atención Nutricional Materno Infantil (ICANMI). El cumplimiento por indicador, etapa de vida y global fue categorizado utilizando los siguientes puntos de corte: mala calidad (≤ 70%), calidad insuficiente (71-89%) y buena calidad (≥ 90%). La percepción sobre las barreras y facilitadores que afectan la atención nutricional materno-infantil fueron identificadas a través de entrevistas semiestructuradas y grupos focales realizadas a profesionales de salud, usuarias y usuarios. Todos los instrumentos cualitativos fueron desarrollados con un enfoque de género e interculturalidad. RESULTADOS: La calidad de la atención nutricional materno infantil durante las cinco etapas de la vida evaluadas fue mala (cumplimiento: ≤12%), mientras que el ICANMI tuvo un cumplimiento de 8.3%. Las principales barreras identificadas para brindar una atención nutricional de alta calidad fueron la falta de conocimiento y capacitación de los profesionales de la salud, la escasez de equipos, medicamentos, personal y materiales, la desaparición del programa social de transferencias monetarias Prospera, la ausencia de una lengua indígena local, entre otros. Así como la persistencia de prácticas como el machismo y otras de control sobre las mujeres. CONCLUSIONES: Estos hallazgos subrayan la necesidad inmediata de implementar iniciativas que mejoren el estándar de atención nutricional en los centros de salud en Chihuahua, Estado de México, Veracruz, Oaxaca, Chiapas y Yucatán. Es necesario que el gobierno y las autoridades sanitarias, junto con diversas partes interesadas, diseñen, implementen y evalúen en colaboración políticas y programas orientados a mejorar la calidad de la atención nutricional, con perspectiva de género e interculturalidad. Este esfuerzo tiene como objetivo mitigar la prevalencia y aparición de diversas formas de desnutrición tanto en la población materna como infantil.

RESUMO

Spinal cord injury (SCI) is a condition that puts the patient's life at risk in the acute phase and, during the chronic stage, results in permanent deficits in motor, sensory and autonomic functions. Isolated therapeutic strategies have not shown an effect on this condition. Therefore, this study aimed to evaluate the effects of electroacupuncture (EA) and curcumin, alone or combined, on the oxidative balance, motor function recovery and amount of preserved tissue following a traumatic SCI. Long-Evans rats were divided into five groups: SHAM, SCI, SCI + EA, SCI + Curcumin, and SCI + EA + Curcumin. Nitric oxide was significantly decreased in the Curcumin group; the EA, Curcumin and SCI + EA + Curcumin groups had significantly decreased hydroxyl radical and lipid peroxidation levels. Motor function recovery and the amount of preserved spinal cord tissue were significantly greater in the EA, Curcumin and EA + Curcumin groups. The results show that EA and Curcumin treatment alone or in combination decreased oxidative stress, improved functional motor recovery and increased the amount of preserved spinal cord tissue following a traumatic injury.

RESUMO

OBJECTIVE: To determine, in a sheep model, the effect of a short-term progestative treatment on growth dynamics and functionality of induced corpora lutea. DESIGN: Observational, model study. SETTING: Public university. PATIENT(S): Sixty adult female sheep. INTERVENTION(S): Synchronization and induction of ovulation with progestogens and prostaglandin analogues; ovarian ultrasonography, blood sampling, and ovariectomy. MAIN OUTCOME MEASURE(S): Determination of pituitary function and morphologic characteristics, expression of luteinizing hormone (LH) receptors, and progesterone secretion of corpora lutea. RESULT(S): The use of progestative pretreatments for assisted conception affect the growth patterns, the expression of LH receptors, and the progesterone secretion of induced corpora lutea. CONCLUSION(S): The current study indicates, in a sheep model, the existence of deleterious effects from progestogens on functionality of induced corpora lutea.
