Association of Methylenetetrahydrofolate Reductase () Polymorphism with Osteosarcoma in a Mexican Population.

The methylenetetrahydrofolate reductase () gene 677C➔T polymorphism is capable of altering folate metabolism and can modify certain neoplasia risk. Reports have suggested that folate can have an influence on bone development and so it is of interest to know if the 677C➔T polymorphism is associated with the malignant transformation process of this tissue. The polymorphism was determined in 55 patients with osteosarcoma and in 180 healthy individuals.

Birth weight, slowness in eating and feeding practices as independent determinants of rapid weight gain.

Aim: Our aim was to identify independent determinants of rapid weight gain in infants at 3-4, 6, and 12 months of age.

Methods: A cohort study was conducted on Mexican term infants in public and private settings between March 2021 and May 2023. Rapid weight gain was defined as a ≥0.

Anthropometric Indicators and Dietary Intake in Toddlers Aged from 12 to 24 Months Who Attended Private Clinics in the Metropolitan Area of Guadalajara.

The objective was to evaluate the anthropometric indicators and dietary intake of toddlers attending private clinics in Guadalajara. In a cross-sectional study, 101 toddlers aged 12 to 24 months were included. They were born full term, had an adequate weight for gestational age, and attended private clinics in Guadalajara.

Adiposity and feeding practices in the first two years of life among toddlers in Guadalajara, Mexico.

Background: Feeding practices in the first two years of life have a direct impact on nutritional status and adiposity. The purpose of this study was to identify the differences in feeding practices during the first two years of life by sex and type of feeding in the first semester of postnatal life and their relationships with adiposity in toddlers.

Methods: An analytical cross-sectional study that included 150 toddlers aged 12 to 24 months who were healthy, full-term, and had adequate weight for their gestational ages, was conducted at the New Civil Hospital and at a private practice in Guadalajara.

Serum 25-Hydroxyvitamin D correlates with systolic blood pressure in obese male schoolchildren.

Introduction: childhood obesity is associated with an increased risk of chronic diseases. We aimed to examine the relation between serum levels of 25-hydroxyvitamin D (25[OH]D) and blood pressure in obese schoolchildren. Material and methods: a cross-sectional study in school-age children with obesity.

Vitamin D and its correlation with blood lipids and intima-media thickness in term infants.

Background: an association between low 25(OH)D levels and blood lipids has been identified in children, adolescents, and adults but not in the early stages of life, and a relation to carotid and aortic intima-media thickness has not been well studied and is controversial. Objective: to identify whether 25(OH)D levels are correlated with blood lipids and aortic and carotid intima-media thickness in infants aged 3 to 9 months. Methods: a cross-sectional study was conducted in 109 healthy term infants between the ages of 3 and 9 months.

Full Breastfeeding Modifies Anthropometric and Body Composition Indicators in Nursing Mothers.

It has been observed that breastfeeding mobilizes the deposits of fat that accumulate during pregnancy and promotes weight loss through energy expenditure. The purpose of this study was to demonstrate that full breastfeeding (FBF) reduces anthropometric and body composition indicators in women between the 8th and the 16th week postpartum. In a nonrandom cohort study, 170 mothers at the Hospital Civil de Guadalajara, Guadalajara, México, were enrolled: FBF 74, partial breastfeeding (PBF) 57, and human milk substitutes (HMS) 39.

Vitamin D status and its relation to insulin resistance in a Mexican pediatric population.

Background Obesity in children and adolescents has increased alarmingly, placing them at a higher risk for impaired glucose tolerance and type 2 diabetes. The prevalence of vitamin D deficiency has increased as well. Vitamin D is critical for glucose homeostasis and insulin secretion.

Factors associated with the stool characteristics of children with cerebral palsy and chronic constipation.

Background: chronic constipation is a common gastrointestinal problem in children with cerebral palsy and several factors can influence the stool frequency, consistency and pH in these cases.

Aim: to identify the association of dietary factors, use of anticonvulsants and family history of constipation with the stool characteristics of children with cerebral palsy and chronic constipation.

Methods: an analytical cross-sectional study was performed of 45 children with cerebral palsy and chronic constipation that included 19 females and 26 males, aged 37 ± 13 months.

Correlation between skinfold thickness and bioelectrical impedance analysis for the evaluation of body composition in patients on dialysis.

Introduction: Patients on dialysis have important changes in body composition.

Objectives: To determine the correlation between skinfold thickness (SKF) and bioimpedance analysis (BIA) for estimating fat mass (FM) and lean body mass (LBM) in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD).

Methods: Cross-sectional study.

Effect of Calcitriol Supplementation on Blood Pressure in Older Adults.

Recent studies suggest that vitamin D plays an important role in the control of blood pressure. Unfortunately, because older adults are more likely to have low 25-hydroxyvitamin-D [25(OH)D] levels, this study investigated whether calcitriol supplementation reduces blood pressure in older adults with hypertension. The design was a double-blind placebo-controlled randomized clinical trial with 36 randomly assigned subjects (71.

Current Backpack Weight Status for Primary Schoolchildren in Colima, Mexico.

The purpose of the study was to identify the current status of backpack weight in primary schoolchildren in Colima, Mexico, in relation to gender, school grade level, and body mass index. A cross-sectional study was conducted on 240 randomly selected children from 20 primary schools. The participating children's parents signed statements of informed consent.

Higher levels of C-reactive protein associated with higher adiposity in mexican schoolchildren.

Introduction: The development of chronic-degenerative diseases secondary to obesity in early infancy has alerted health providers to the importance of identifying the risk factors for obesity and assessing preventive treatment to reduce risks. Studies performed on a pediatric population have examined the role of inflammatory biomarkers (specifically CRP and TNF-α) and adiposity with inconsistent results.

Objective: To assess the relationship between the serum levels of C-reactive protein and tumor necrosis factor-alfa with adiposity measured by bioimpedance analysis in schoolchildren.

Correlation between percentage of body fat measured by the Slaughter equation and bio impedance analysis technique in Mexican schoolchildren.

Introduction: Obesity is considered one of the most serious public health problems of the 21st century in children and adolescents. The percentile or Z-score of the body mass index is widely used in children and adolescents to define and assess overweight and obesity, but it does not determine the percentage of total body fat. Other anthropometric measurements that determine total body fat are skinfold thickness and methods of body composition assessment such as bio impedance analysis, both of which are rapid and inexpensive.

Levels of eicosapentaenoic acid in obese schoolchildren with and without insulin resistance.

Background: Obesity in children is now an increasing health risk worldwide in which the insulin-resistance can be present. Studies have linked a diet rich in n-3 fatty acids with a lower prevalence of insulin-resistance.

Objective: To compare the levels of eicosapentaenoic acid among obese children with and without insulin-resistance.
