Work-related accidents, musculoskeletal pain, and health-related quality of life among Pantanal farm workers in Brazil and in Mexico.

Introduction: The agricultural and livestock production of Brazil and Mexico stand out in the global scenario. In this context, this economic activity is one of the most vulnerable, presenting alarming incidence and prevalence rates of work-related accidents and diseases.

Objectives: This study characterized and compared the occurrence of occupational accidents and musculoskeletal pain, as well as the health-related quality of life of Pantanal farm workers (pantaneiros) in Brazil and their equivalents in Mexico - the ganaderos.

Lieber-DeCarli Diet Promotes Different Hepatic Histological Changes During Early and Late Pregnancy: An Example of Maternal Resilience.

Background/aim: During pregnancy, maternal liver can be affected by ethanol (ETOH) intake, whose effects depend on concentration levels ingested. This study aims to describe histological and serum marker characteristics of maternal liver during two metabolic conditions: gestation (G), and sustained ETOH intake, in early and late pregnancy.

Materials And Methods: Wistar rats were fed with Lieber-DeCarli diet during pregnancy, following an experimental protocol that allows a semi-chronic intake of ETOH (5%).

Effects of Low Protein-High Carbohydrate Diet during Early and Late Pregnancy on Respiratory Quotient and Visceral Adiposity.

Background: Low Protein-High Carbohydrate (LPHC) diet during pregnancy is considered a nutritional and health problem related to the development of maternal metabolic alterations, such as fatty liver and obesity in the perinatal and postnatal period. It is known that increase in visceral adiposity tissue (VAT) modulates maternal metabolic rate, with the respiratory quotient (RQ) being a parameter related to that variable; however, it is unknown whether LPHC intake during pregnancy affects the VAT and the RQ. In this study, we examine if consumption of LPHC during pregnancy modifies the VAT and RQ in early and late periods of pregnancy.

Changes in amino acid profiles and liver alterations in pregnant rats with a high carbohydrate/low protein diet.

Introduction And Aim: Intake of a high-carbohydrate, low-protein diet (HCD/LPD) during pregnancy promotes metabolic disturbances. It has been suggested that liver function during pregnancy contributes to the synthesis of proteins necessary for fetal development during this stage. The liver is a site of response to the synthesis of macronutrients such as proteins.

[Levels of oxidative stress in serum and dietary behavior in adults in a rural area of Jalisco, Mexico].

Introduction: The feeding behavior establishes a relation of humans with food, includes food habits that could be involved with oxidative stress.

Objective: To evaluate the relation of indicators of oxidative stress (lipid peroxides) and antioxidant (ascorbic acid, catalase, superoxide dismutase) with feeding behavior in adults of Teocuhitatlan Corona, Jalisco, Mexico.

Method: Study observational, descriptive, cross-sectional of 44 adults with 43 to 88 years, was used a instrument of feeding behavior.

CD28-, CD45RA(null/dim) and natural killer-like CD8+ T cells are increased in peripheral blood of women with low-grade cervical lesions.

Background: In response to antigen naive CD8+, T cells differentiate into effector cells, which express Natural killer (NK) receptors, lose CD28 expression, and die by apoptosis. However, in smaller quantities, the cells are retained for subsequent exposure to the same antigen. Knowledge is limited regarding whether the percentages of CD28-, Effector memory (EMRA(null/dim)), and the CD16+/CD56 + CD8+ T cells of women with low-grade cervical lesions are altered at a systemic level.

[Glucose, body mass index and pre-neoplastic lesions in the cervix].

Background: The obesity and abnormal blood glucose level has been associated with cervical cancer development; however, few studies have been performed about this relation.

Objective: Evaluate the blood glucose levels and body mass index (BMI) in women with human papilloma virus infection (HPV-I) and cervical intraepithelial neoplasia (CIN-I).

Patients And Method: Transversal study of 44 women diagnosed with HPV-I and CIN-I from September to December 2010 in Dysplasia Clinic of Regional Hospital of Guzman City, Federal entity of Jalisco, Mexico.

[Risk behavior due to alcohol consumption and quality of life in university students].

Objective: to measure the risky behavior (RB) to alcohol consumption, the quality of life (QOL) and the association between both.

Methods: a censal sample of 380 students (first year adolescents who entered a University Center in 2006) completed a self-administered on-line questionnaire based on the Spanish version of Youth Quality of Life- Research version (YQRL-R) perceptive module with four domains (general, personal, relationship, environment) and the Youth Risk Behavior Surveillance YRBS 2007 from which it took four variables related to alcohol use and in addition sociodemographic variables. Logistic Regression Multinomial models were used to assess interaction effects and predict QOL based on RB by gender, employment and socioeconomic position.
