Association between BMI z-score and body composition indexes with blood pressure and grip strength in school-age children: a cross-sectional study.

Childhood obesity is linked to diverse health outcomes, including elevated blood pressure (EBP). Emerging evidence showed that excess fat mass (FM) may have a deleterious impact on blood pressure even in normal-weight children. The primary objective of this study was to assess the association between body weight status by BMI z-score and body composition parameters by conventional bioelectrical impedance analysis (BIA) and bioelectrical impedance vector analysis (BIVA).

Herbal Nephropathy.

An estimated one-third of adults in developed countries and more than 80% of the population in many low- and middle-income countries use herbal and traditional medicines to promote health or for the treatment of common diseases. Herbal medicines can cause kidney damage as a result of intrinsic toxicity, adulteration, contamination, replacement, misidentification, mistaken labeling, and unfavorable herb-drug interactions. The kidneys, due to their high blood flow rate, large endothelial surface area, high metabolic activity, active uptake by tubular cells, medullary interstitial concentration, and low urine pH are particularly vulnerable to development of toxic injury in the form of different syndromes like acute kidney injury, nephrolithiasis, chronic interstitial fibrosis, or uroepithelial cancer.

Effect of Oral Nutritional Supplementation With and Without Exercise on Nutritional Status and Physical Function of Adult Hemodialysis Patients: A Parallel Controlled Clinical Trial (AVANTE-HEMO Study).

Objective: Protein energy wasting affects the nutritional status (NS) and physical function (PF) of dialysis patients. Among the different anabolic strategies to improve NS and PF, oral nutritional supplementation (ONS) and resistance exercise (RE) or aerobic exercise (AE) have been shown to be effective. Nevertheless, the combination of both anabolic strategies has not been completely evaluated.

Dietary Phosphorus to Protein Ratio for the Mexican Population with Chronic Kidney Disease.

Objective: Hyperphosphatemia is a major contributor to poor outcomes among cases of chronic kidney disease. Considering that foods with high protein content are major sources of phosphorus, a more suitable dietary phosphorus measure is the phosphorus to protein ratio. However, Mexican phosphorus to protein ratio tables do not exist.

Combined assessment of nutritional status in patients with peritoneal dialysis using bioelectrical impedance vectors and malnutrition inflammation score.

Background And Objective: Protein energy wasting (PEW) is a common syndrome in patients with chronic kidney disease, related to changes in hydration status, decreased food intake and inflammation. There are several tools for the assessment and diagnosis of such alterations. Bioimpedance vector analysis (BIVA) assess the state of nutrition and hydration, but not the inflammatory component, while the malnutrition inflammation score (MIS) comprises the inflammatory and nutritional factors, but not the state of hydration.

[Renal disease].

Chronic renal failure in its various stages, requires certain nutritional restrictions associated with the accumulation of minerals and waste products that cannot be easily eliminated by the kidneys. Some of these restrictions modify the intake of proteins, sodium, and phosphorus. Milk and dairy products are sources of these nutrients.

Effect of Resistance Exercises on the Indicators of Muscle Reserves and Handgrip Strength in Adult Patients on Hemodialysis.

Objective: Although resistance exercise has been associated with improvement in the muscle reserves, muscle strength and quality of life in end-stage renal disease patients, the objective of this paper is to evaluate the effect of resistance exercise performed during hemodialysis sessions on the anthropometric indicators of muscle reserve and handgrip strength in sedentary malnourished patients with end-stage renal disease.

Methods: Patients were randomized to perform resistance exercise during hemodialysis sessions with ankle weights and resistance bands. The exercises were performed twice a week over the course of 12 weeks.

Effect of probiotics on human blood urea levels in patients with chronic renal failure.

Introduction: Patients with chronic kidney disease (CKD) show an increase in bowel aerobic bacteria that produce uremic toxins and decreased anaerobic bacteria as bifidobacteria and lactobacillus. The latter can be used as probiotics. The probiotic with greater availability in Mexico, is the lactobacillus casei shirota (LcS), currently there is no known LcS specified dose that produces a benefit to the patient with CKD.

Assessment of the reliability and consistency of the "malnutrition inflammation score" (MIS) in Mexican adults with chronic kidney disease for diagnosis of protein-energy wasting syndrome (PEW).

Background: The protein-energy wasting syndrome (PEW) is a condition of malnutrition, inflammation, anorexia and wasting of body reserves resulting from inflammatory and non-inflammatory conditions in patients with chronic kidney disease (CKD).One way of assessing PEW, extensively described in the literature, is using the Malnutrition Inflammation Score (MIS).

Objective: To assess the reliability and consistency of MIS for diagnosis of PEW in Mexican adults with CKD on hemodialysis (HD).

[Bioimpedance vector analysis for body composition in Mexican population].

Objective: To construct bivariate tolerance ellipses from impedance values normalized for height, which can be used in Mexican population for the assessment of body composition and compare them with others made in different populations.

Methods: Body composition was assessed by bioelectrical impedance analysis (BIA) in 439 subjects (204 men and 235 women), 18 to 82 years old, with a BMI between 18-31, using an impedanciometer Quadscan 4000. Resistance, reactance and phase angle were used to calculate bioelectrical impedance vectors and construct bivariate tolerance ellipses.
