Fluoride Concentration in Urine after Supplementation with Quelites in a Population of Adolescents.

Wild plants have detoxifying and protective properties. They reduce or neutralize the toxic effects caused by chemical agents and pollutants and have beneficial effects on the nutritional and health status. This research was conducted to complement a previous clinical intervention in which participants were exposed to high concentrations of arsenic and fluoride in drinking water to discover similarities or differences in the pattern of fluoride (F) excretion after supplementation with partial areas of purslane and quelite cenizo (SP-Q).

Sensitivity and specificity of body mass index and main risk factors for cardiovascular disease in middle-income urban participants in Guanajuato, Mexico.

Introduction: several studies have questioned body mass index (BMI) as an accurate diagnostic tool for obesity and therefore a predictor of cardiovascular risk. But BMI is widely used currently. Objective: we analyzed the sensitivity and specificity of BMI and compared cardiovascular risk factors in middle-income urban participants in Guanajuato, Mexico, at different ages.

[Food insecurity and its association with obesity and cardiometabolic risks in Mexican women].

Design: a systematic review. Data sources: MEDLINE, Embase, CINAHL Plus, Web of Science, CAB Abstracts and PAIS Index.

Repurposing Individualized Nutritional Intervention as a Therapeutic Component to Prevent the Adverse Effects of Radiotherapy in Patients With Cervical Cancer.

Worldwide, cervical cancer was the fourth leading cause of cancer death among women, while in Mexico was the second cause (5.28%). Cancer patients receiving chemotherapy and radiotherapy have a high risk of malnutrition secondary to the disease and treatment, affects the patient's overall, with adverse effects on gastrointestinal symptoms.

5'UTR methylation in different genes from workers exposed to volatile organic compounds: A new insight for considering an epigenetic mark as a functional correlate.

Unlabelled: Gene-specific methylation has been related with transcriptional/translational consequences in different cells; also, this epigenetic modification is affected by environmental exposures. In previous studies, CYP2E1 activity in toluene-exposed workers was decreased compared to controls, however, CYP2E1 promoter methylation levels did not show significant differences. Here, we compared gene-specific methylation levels at the 5'UTR region, in a subset of workers whom already participated in two former studies, compared to controls.

Cancer prevention programmes in Mexico: are we doing enough?

Cancer has increased in all the countries of the world and Mexico is no exception. The recognised risk factors for the main types of cancer are reviewed and searched through the Mexican government web pages and cancer prevention programmes to tackle the risk factors in the population. The Mexican government, a member of the World Health Organization, shows that the main approach is an early diagnosis rather than prevention, forgetting that an ounce of prevention is better than a pound of cure.

Effect of a Supplementation with Two on Urinary Excretion of Arsenic in Adolescents Exposed to Water Contaminated with the Metalloid in a Community in the State of Guanajuato, Mexico.

are Mexican wild plants, reported as excellent sources of nutritional compounds such as amino acids (serine, glycine, and cysteine), minerals (Mg, Fe, and Zn), and phytochemicals, as phenolic acids (chlorogenic acid) and flavonoids (phloridzin and naringenin); on the other hand, high biological activity has been shown in these compounds. This work aimed to evaluate the effect of a supplementation with two endemic of Mexico ( L. and L.

Association between food insecurity and perinatal risk factors with hearing problems in preterm birth.

Background: hearing disorders in the premature newborns impact on their development and language and therefore, on their quality of life. Several risk factors have been associated to these conditions, but little is known about socioeconomic, nutrition factors and food security. Objective: to analyze the association between food security and prenatal risk factors in newborns with hearing disorders.

[Threats, challenges and opportunities for paediatric environmental health in Europe, Latin America and the Caribbean].

In a world that is increasingly technological and interconnected, but also more violent, overexploited and polluted, Paediatric Environmental Health (PEH) is one of the best contributions to improve global health. Few areas of the planet have a high affinity with common values and interests, such as the European Union (EU), Latin America and the Caribbean (LAC). The investments and actions of the PEH in pre- and postnatal periods during the first two decades of life will generate countless benefits in the health and well-being during the human life span.

[Effect of a four-week vitamin and mineral supplementation on the nutritional status and urinary excretion of arsenic in adolescents].

Introduction: adequate nutrition in adolescence is important for growth and development. There are environmental factors that cannot be avoided, such as exposure to heavy metals through natural sources such as water. Arsenic is a metalloid that can cause damage to health (alterations in nutritional status, diabetes, cancer) and it has been found in concentrations higher than those allowed in drinking water.

Parameters of lung inflammation in asthmatic as compared to healthy children in a contaminated city.

Background: The impact of air pollution on the respiratory system has been estimated on the basis of respiratory symptoms and lung function. However; few studies have compared lung inflammation in healthy and asthmatics children exposed to high levels of air pollution. The aim of the study was to elucidate the modulatory effect of air pollution on Cysteinyl-leukotrienes (Cys-LTs) levels in exhaled breath condensate (EBC) among healthy and asthmatic children.

Breastfeeding and metabolic indicators in Mexican premature newborns.

Background: Morbidity and mortality rates are higher among preterm infants due to physiological immaturity and greater growth demands. Nutritional intervention contributes to proper weight gain, which translates into better growth and neurological development, and prevents the onset of metabolic complications. The effect of breastfeeding duration was studied in the analytic profile at the end of the first six months of life.

Weight gain and metabolic complications in preterm infants with nutritional support.

Objective: To analyze the weight gain and to describe the metabolic complications in preterm newborns with nutritional support (NS) and to describe nutritional practices in the first month of hospitalization for 52 preterm newborns.

Material And Methods: Descriptive and prospective study of preterm infants (30-36 gestational weeks), with birth weight > 1 kg, hospital stay > 12 days, without respiratory support or complications, conducted at a public hospital in Leon, Guanajuato, Mexico from January to November 2006. Weight, serum glucose, insulin, cholesterol, triglycerides, gamma-glutamyltransferase, creatinine, urea nitrogen, type of NS (parenteral PN, enteral EN, mixed MN), energy content, and macronutrient intake were measured weekly.

[Comparison between five growth curves used in a public hospital].

Objective: To compare five curves routinely used for growth evaluation in preterm newborns in a public hospital in Leon, Guanajuato, and to identify those with similar diagnosis according to the reference curve (Williams) in order to determine their usefulness in the clinical practice.
