Plasma Levels of Magnesium, Calcium, Calcium to Magnesium Ratio, and Associations with Metabolic Syndrome and Cardiometabolic Risk Factors.

Magnesium and calcium are elements that have been associated with cardiometabolic risk factors related to metabolic syndrome (MetS). However, there are gaps in the knowledge regarding the impact of the calcium to magnesium (Ca/Mg) ratio in plasma. Thus, we aim to evaluate the associations between magnesium and calcium levels in plasma, and the Ca/Mg ratio in plasma with MetS components and other cardiometabolic risk factors.

Plasma lipid metabolites as potential biomarkers for identifying individuals at risk of obesity-induced metabolic complications.

Lipidomics studies have indicated an association between obesity and lipid metabolism dysfunction. This study aimed to evaluate and compare cardiometabolic risk factors, and the lipidomic profile in adults and older people. A cross-sectional study was conducted with 72 individuals, divided into two sex and age-matched groups: obese (body mass index-BMI ≥ 30 kg/m; n = 36) and non-obese (BMI < 30 kg/m; n = 36).

Food insecurity in a Brazilian transgender sample during the COVID-19 pandemic.

Transgender people often live with social vulnerability, largely promoted by gender-based prejudice. Our aim in this article was to raise preliminary data on how the COVID-19 pandemic and perceived prejudice have contributed to the problem of food and food insecurity in the transgender communities in Brazil. We conducted a web-based cross-sectional study, in which 109 transgender people from all regions of Brazil participated.

Development and validation of predictive workable weight equations for Brazilian older adult residents in long-term care institutions.

Background: Weight measurement is important in the nutritional anthropometric monitoring of older adults. When this measurement is not possible, estimates may be used.

Aim: Developing and validating weight predictive equations for older adult residents in long-term care institutions in Brazil.

Histopathological prognosis of papillary thyroid carcinoma associated with nutritional status of vitamins A and E.

Background/objectives: Experimental and clinical studies have shown that vitamins A and E can inhibit cancer formation and progression. The unfavourable status of these vitamins can represent risk factors for the disease. This study aimed to evaluate the associations between the nutritional status of vitamins A and E (serum levels and dietary intake) and histopathological outcomes in Papillary Thyroid Carcinoma (PTC) patients.

Protocol for systematic reviews of school-based food and nutrition education intervention for adolescent health promotion: Evidence mapping and syntheses.

Background: Nutrition is an important modifiable factor in combating overweight and obesity among adolescents. School has been indicated as an effective environment for influencing eating behavior; however, recent reviews assessing school-based interventions specifically for adolescents are scarce. Therefore, we propose the present systematic review with the aim to comprehensively review the quantitative and qualitative literature on the effects of school-based food and nutrition education interventions on adolescent health promotion through healthy eating habits.

Instruments for evaluation of motivations for weight loss in individuals with overweight and obesity: A systematic review and narrative synthesis.

This systematic review aims to identify instruments used to assess motivations for weight loss in individuals with overweight and obesity from different age groups, such as children, adolescents, adults, and older adults. The virtual search was carried out using the PubMed, Scopus, LILACS, and ADOLEC databases, and by manual search. The following descriptors were used: questionnaire, scale, instrument, evaluation, motivation, motive, reason, "lose weight," "losing weight," "weight loss," and slimming.

Motivations for weight loss in adolescents with overweight and obesity: a systematic review.

Background: Adolescents with overweight and obesity report various motivations for weight loss other than the desire for better health. However, there is little evidence regarding the main motivations for weight loss in adolescents. The present systematic review aimed to identify the motivations for weight loss in adolescents with overweight and obesity.

Plasma zinc in institutionalized elderly individuals: Relation with immune and cardiometabolic biomarkers.

Changes in zinc metabolism caused by aging and the institutionalization process may contribute to zinc deficiency in elderly individuals. Hypozincemia results in changes in glycemic, lipid, and inflammatory profiles. The aim of this study was to evaluate plasma zinc concentrations and their relationships with sociodemographic, dietary, inflammatory, and cardiometabolic biomarkers in institutionalized elderly individuals.

Dietary patterns of young adolescents in urban areas of northeast Brazil.

Background: Temporal trends in dietary patterns reveal associations between food consumption and increased prevalence of non-communicable chronic disease.

Objectives: This study characterized dietary patterns in adolescents in urban area located in northeast of Brazil, relating it to the markers of a healthy diet.

Methods: A cross-sectional study used two 24-hour recalls to assess dietary intake in 430 public school students from Natal-RN, Brazil.

Prediction equations for fat and fat-free body mass in adolescents, based on body circumferences.

Background: Fat mass (FM) and fat-free body mass (FFB) are important parameters for assessing nutritional status, since they are associated with higher prevalence of excess body fat and malnutrition worldwide.

Aim: To develop prediction equations for fat and fat-free body mass in adolescents using body circumferences.

Subjects And Methods: This cross-sectional study included 218 adolescents (10-16 years) with normal weight as defined by body mass index.

Socioeconomic conditions as determining factors in the prevalence of systemic and ocular toxoplasmosis in Northeastern Brazil.

Objective: To determine the prevalence of systemic and ocular toxoplasmosis among 1024 students in the city of Natal, Northeastern Brazil, and correlate it with demographic, socioeconomic and epidemiological risk factors.

Methods: The study population was randomly selected, asked to fill out a questionnaire, provide a blood sample for IgG and IgM (MEIA) serology and a hemogram, and undergo an eye examination.

Results: The seroprevalence for IgG was 46% (95% CI = 42.
