Diseño Y Validación De Un Modelo Antropométrico Para Evaluar La Masa Grasa Corporal En Mujeres Mexicanas

Objective: Develop a multiple linear model, using the least squares method to correlate fat mass (kg), using anthropometric variables obtained from a sample of women from northwest Mexico. Materials: ISAK standardization was used in this study to collect measurements. The statistical criteria R², EER, VIF, Cp, and RMSE were used to evaluate the performance of the model. Method: Descriptive observational cross-sectional study to determine the fat mass of a sample of 95 women from the northwest of Mexico with normal weight and overweight. Results: The adjusted model (M8p) is made up of eight predictors that are statistically most representative in this study: weight, 6 skinfolds, and biliocrestal diameter. The fat mass of the sample was determined using air displacement plethysmography (reference), the mean obtained for the fat mass was 21.3 kg with a standard deviation of ±9.3, the M8p model predicts 20.9±9.9 kg which is 2% below the reference method used. The statistical criteria of the adjusted model are, R²Adj=0.92, SER= 2.9 kg, VIF 4.8, Cp= 7.8, and RMSE= 3.08 obtained with the adjustment sample (70 women), the validation sample (25 women) obtained a value RMSE of 3.15, so the model has predictive capacity. Conclusions: The developed model adequately predicts the fat mass of women with and without excess body fat mass, which makes it valid for use in similar samples, giving the health professional one more option to adequately evaluate this tissue, which will allow giving a optimal treatment on an individualized basis.Objetivo: Desarrollar un modelo lineal múltiple, usando el método de mínimos cuadrados para correlacionar la masa grasa (kg), utilizando variables antropométricas obtenidas de una muestra de mujeres del noroeste de México.

Reviving Lonidamine and 6-Diazo-5-oxo-L-norleucine to Be Used in Combination for Metabolic Cancer Therapy

Abnormal metabolism is another cancer hallmark. The two most characterized altered metabolic pathways are high rates of glycolysis and glutaminolysis, which are natural targets for cancer therapy. Currently, a number of newer compounds to block glycolysis and glutaminolysis are being developed; nevertheless, lonidamine and 6-diazo-5-oxo-L-norleucine (DON) are two old drugs well characterized as inhibitors of glycolysis and glutaminolysis, respectively, whose clinical development was abandoned years ago when the importance of cancer metabolism was not fully appreciated and clinical trial methodology was less developed. In this review, a PubMed search using the words lonidamine and 6-diazo-5-oxo-L-norleucine (DON) was undertaken to analyse existing information on the preclinical and clinical studies of these drugs for cancer treatment. Data show that they exhibit antitumor effects; besides there is also the suggestion that they are synergistic. We conclude that lonidamine and DON are safe and potentially effective drugs that need to be reevaluated in combination as metabolic therapy of cancer

CHARACTERISTICS AND SOCIO-PRODUCTIVE PROBLEMS OF WOMEN MEZCAL PRODUCERS IN OAXACA, MEXICO

Objective: To analyze the characteristics and socio-productive problems of the mezcal women of Oaxaca, Mexico. Design/methodology/approach: The information was obtained in the field through a semi-structured interview with 20 women mezcal producers. Results: The women are in mid-adulthood, have basic education, and with extensive experience in the activity. It was identified that 35% of them make decisions entirely about the business and the home. The price of mezcal (35%) and the shortage of maguey (30%) are the main problems perceived in the activity. Women face social limitations such as work overload at home, no access to productive support, and low participation in rural organizations. Limitations of the study/implications: It is convenient to carry out a greater number of studies on mezcal women in Oaxaca. Findings/conclusions: The collective work and organization can be an alternative that improves the benefits and quality of life of the families of mezcal women. There is a need to design public policies with a gender perspective and appropriate to the needs of the women who participate in the activity.Objective: To analyze the characteristics and socio-productive problems of women mezcal producers of Oaxaca, Mexico.
