Has the time come to replace mercury sphygmomanometers by automated devices for measuring blood pressure in children?

Blood pressure assessment in children has acquired special relevance to prevent cardiovascular di... more Blood pressure assessment in children has acquired special relevance to prevent cardiovascular diseases later in life, therefore, there is a need to implement appropriate measurement techniques and suitable and accurate support instruments. Traditionally, blood pressure has been measured with mercury sphygmomanometers using the auscultatory technique and, at present, it is even considered to be the gold standard. Nevertheless, this device has a number of measurement pitfalls that, combined with its potential ecological risk owing to accidental mercury pollution, has stimulated the development and design of automated devices, which mainly use the oscillometric method for blood pressure measurement. Automated devices are mercury free and they have abolished some measurement procedures errors, mainly those related to the observer. However, these instruments are not better than mercury sphygmomanometers when accuracy parameters regarding blood pressure measurement are taken into consideration; on the other ha...

Both health conditions have a higher prevalence among women of childbearing age. Physiopathology, overweight and obesity are characterized by a chronic oxidative stress status, which has deleterious effects on mothers and children. Hence, we determine whether the qualities of diet during pregnancy and maternal pregestational body mass index (BMI) are associated with increased oxidative stress markers in mothers and newborns. Two hundred forty-two (242) mother-newborn pairs were classified according to their pregestational BMI. Information on food intake was collected using a food frequency questionnaire in the third trimester of pregnancy. Levels of Malondialdehyde (MDA) and Nitric Oxide (NO) were measured in plasma from mothers at the end of the third trimester of pregnancy and from cord blood at birth. MDA and NO levels in mother–newborn pairs with maternal pregestational overweight ...

This is a legal instrument established by the Ministries of Public Education and Health to regulate that foods and beverages sold and consumed in school cafeterias will be healthful, in order to reduce the high rates of overweight and obesity in school-aged children. All of the chapters in the AGREEMENT have been analyzed to determine their pertinence to overcome the problem of overweight and obesity: legal aspects, physical characteristics of the cafeteria, and the committees to determine the functions of the cafeteria. Furthermore, analyses have been made of the scientific terms where the nutritional composition of the healthy products is defined. It is expected that foods and beverages sold in school cafeterias will be changed to healthful items over the next 3 years. A list of statements conside...

The aim of this study is to assess the association between the degree of insulin resistance and the different components of the metabolic syndrome among obese children and adolescents. Methods: An analytical, cross-sectional and population-based study was performed in forty-four public primary schools in Campeche City, Mexico. A total of 466 obese children and adolescents between 11-13 years of age were recruited. Fasting glucose and insulin concentrations, high density lipoprotein cholesterol, triglycerides, waist circumference, systolic and diastolic blood pressures were measured; insulin resistance and metabolic syndrome were

SIGNIFICANT INVERSE RELATIONSHIP BETWEEN ANTIBODIES AGAINST Entamoeba histolytica, Ascaris lumbricoides, Toxocara spp AND THE PRESENCE OF TYPE 1 DIABETES MELLITUS

Here we analyzed the association of the presence of parasites and antibodies to Ascaris lumbricoides, Toxocara spp and Entamoeba histolytica with HLA-DR genotypes in 26 patients with T1DM who attended to the Children’s Diabetes Clinic (CANDI) at t...

The aim of this study was to assess the association between health beliefs and glycated hemoglobin levels in Mexican patients with type 2 diabetes. Methods: An analytical cross-sectional study was conducted, and 336 patients were included. Fasting blood levels of glycated hemoglobin, glucose, cholesterol; triglycerides, high-density lipoprotein cholesterol (HDL-c), and lowdensity lipoprotein cholesterol (LDL-c) were measured. Body fat percentage, weight, height; waist circumference, and systolic and diastolic blood pressures were also obtained. A previously validated self-administered questionnaire was used to assess the health beliefs with regards to non-pharmacological treatment. Health beliefs were classified as positive, neutral, and negative. Results: The average age of patients was 54.7 ± 8.5 years, with a higher proportion of females (69%). The questionnaire had a good internal consistency with a Cronbach's alpha score of 0.83. More than 90% of patients attributed a health benefit to diet and exercise, 30 to 40% experienced barriers, and more than 80% had a perception of complications associated to uncontrolled diabetes. Patients with positive health beliefs had lower HbA1c levels (8.2 ± 1.7%) compared to those with neutral (9.0 ± 2.3%), or negative (8.8 ± 1.8%; p = 0.042). The LDL-c levels were lower (p = 0.03), and HDL-c levels were higher (0.002) in patients with positive heath beliefs. Conclusions: Positive health beliefs are associated with better metabolic control indicators in patients with type 2 diabetes.
