RESUMO

This article provides relevant results of a cleaner production program conducted in a company dedicated to remanufacturing air compressors in the city of Hermosillo, Sonora, Mexico. The overall study design was based on an integration of acknowledged cleaner production and pollution prevention programs. Although this kind of program also involves environmental issues, this study focused on occupational health and safety by addressing different aspects of the work environment: ergonomic, physical (noise and lighting), and chemical. Particularly, ergonomic aspects were evaluated through the Modular Arrangement of Predetermined Time Standards (MODAPTS) method. For physical aspects, noise and lighting were addressed through Standard No. NOM-011-STPS-2001 and Standard No. NOM-025-STPS-2008 respectively. In addition, chemical aspects were analyzed through material safety data sheets and different search tools. Root causes of each risk were identified, and options to prevent, eliminate, and/or reduce each risk have been provided.

RESUMO

INTRODUCTION: Acquired brain injury (ABI) during childhood typically causes behavior problems in the child and high levels of stress in the family. The aims of this study are: (1) to investigate the effectiveness and feasibility of a parenting intervention in improving behavior and self-regulation in Mexican children with ABI compared to telephone support; (2) to investigate the effectiveness and feasibility of a parenting intervention in improving parenting skills, parent self-efficacy and decreasing parental stress in parents of children with ABI compared to telephone support. Our secondary aims are (1) to explore the impact that parent characteristics have on the intervention outcomes; (2) to investigate if changes are maintained 3 months after the intervention. METHODS: The research design is a blind randomized controlled trial (RCT). Eligible participants include children with a diagnosis of ABI, between 6 and 12 years of age, and their parents. Sixty-six children and their parents will be randomly allocated to either a parenting program group or telephone support group. The parenting program involves six face-to-face weekly group sessions of 2.5 h each. Participants in the control group receive an information sheet with behavioral strategies, and six weekly phone calls, in which strategies to improve academic skills are provided. Children and their parents are evaluated by blind assessors before the intervention, immediately after the intervention and 3-months post-intervention. DISCUSSION: This study will be the first to evaluate the efficacy and feasibility of a parenting program for Mexican parents of children with ABI. TRIAL IDENTIFIER: ACTRN12617000360314.

RESUMO

OBJECTIVE: To identify the presence of environmental factors linked to the onset of allergies and asthma in the homes of children participating in an early detection program that were identified with sensitivity to common allergens in the region of Sonora, Mexico. METHODS: A walkthrough assessment was carried out in the homes of sensitized children; the research tools were the questionnaire and environmental checklist proposed by the Lowell Healthy Homes Program of the University of Massachusetts-Lowell. RESULTS: The results showed the presence of environmental allergen sources, to which most of the children in the study are sensitized, as well as the environmental conditions and habits that determine the quality of the indoor air of the households, were both related to triggering allergies and asthma in this population. A statistically significant association was found between the visual observation of dust inside homes and the sensitivity of children to dust mites. CONCLUSIONS: Dust found inside the home was the most relevant environmental factor related to positive cases of IgE in children. Early detection of allergies in children in the study and the methodology used in this investigation provided a useful framework for the design of plans and intervention alternatives in these homes to prevent the development of allergies and asthma panorama. These plans should be designed with a multidisciplinary approach to impact social, environmental and economic benefits in the family, improving the living conditions of the study population and contributing to the sustainable development goals of the United Nations for 2030.

RESUMO

Se efectuó una revisión sobre el síndrome frágil X, del cual en Cuba no existían reportes desde el punto de vista poblacional, hasta la realización del estudio psicopedagógico, social y clínico genético de las personas con retraso mental; mediante el cual pudo detectarse un total de 75 personas con defectos del gen FMR-1, que es el gen relacionado con esta enfermedad. Es un síndrome causado en la gran mayoría de los casos por la amplificación o mutación dinámica de las repeticiones del trinucleótido citosina-guanina-guanina (CGG) en la región promotora del gen FMR-1. La traducción de este gen da lugar a una proteína denominada FMRP. Se plantea que la ausencia o deficiencia de esta proteína ocasiona modificaciones de la actividad neuronal. Hoy día no hay cura para el síndrome frágil X, aunque se están desarrollando experimentos basados tanto en la terapia como la ingeniería genética, consistentes en reproducir la carencia de la proteína causante de la enfermedad. El tratamiento médico se limitará a reducir y palear todos los síntomas que pueden observarse en este síndrome. La temprana identificación del síndrome frágil X, resulta muy beneficiosa para los padres y la familia del paciente; pues reduce el impacto psicológico inicial y propicia que se apliquen programas de intervención precoz; proporcionando una mejor comprensión de la historia natural de la enfermedad y el estudio genético entre otros aspectos.
