Association between hypovitaminosis D and sarcopenic obesity in patients with chronic kidney disease stages 3 and 4.

The relationship between sarcopenic obesity and hypovitaminosis D in individuals with chronic kidney disease is complex and has significant impacts on muscle and bone health. An observational, cross-sectional, and analytical study was conducted to analyze possible associations between serum vitamin D levels and sarcopenic obesity in patients with chronic kidney disease stages 3 and 4 in a cohort of patients under nephrology care. The presence of sarcopenic obesity was assessed using bioimpedance criteria, and vitamin D levels were measured and recorded for each patient.

Relationship between hypovitaminosis D and sarcopenia in patients with stage 3 and 4 chronic kidney disease in Colombian patients.

Background: Sarcopenia is a condition associated with aging and multiple medical conditions such as CKD and hypovitaminosis D.

Methods: An observational cross-sectional study was carried out, based on patients registered in a database of specialized nephrology consultation in the city of Manizales, Colombia. 101 patients over 18 years of age who had stage 3 or 4 CKD were included.

Cut-off points for low skeletal muscle mass in older adults: Colombia other populations.

The European Working Group on Sarcopenia in the Elderly defined sarcopenia as a geriatric syndrome with a diagnostic criteria of low skeletal muscle mass (LMM). Various sarcopenia consensuses recommend as cut-offs for LMM, the use of below 2 SDs from the mean skeletal muscle mass index (SMI) of a young reference group. Given the contrast between reported cut-offs, the objective of this study was to establish cut-offs for LMM from older adults in Manizales and compare them with those published in the literature.

Potential Hypoglycemic and Antilipidemic Activity of Polyphenols from (Granadilla).

The consumption of fruits or by-products from plants of the Passifloraceae family has been associated with multiple health and nutritional benefits, due to their phenolic compound content. Likewise, the effects of polyphenols from (green tea) have been explored and are considered a reference for different biological actions of these bioactive substances. This study compared the hypoglycemic and antilipemic activity of polyphenol-rich extracts of Juss (passion fruit) and (green tea) given to a group of Wistar rats induced to be overweight.

Effect of 8-Week Consumption of a Dietary Pattern Based on Fruit, Avocado, Whole Grains, and Trout on Postprandial Inflammatory and Oxidative Stress Gene Expression in Obese People.

Overweight and obesity constitute a major global public health problem. Healthy dietary patterns induce changes at the molecular level. Currently, there are no studies evaluating the effect of a diet based on fruit, avocado, whole grains, and trout (FAWGT diet) on the expression of obesity-related genes.

Flavonoid/Polyphenol Ratio in and as an Indicator of Effective Antioxidant Action.

Studies on polyphenols and flavonoids in natural products reveal benefits in the prevention of multiple diseases. Proper extraction, treatment of extracts, and quantification of polyphenols and flavonoids demand attention from the scientific community in order to report more specific biological action. Total polyphenol content (TPC) and total flavonoid content (TFC) (measured at three different times) of ethanol, methanol and acetone extracts of (aguaje) and (copoazú) fresh pulp, from the Colombian Amazon region, were evaluated with the purpose of focusing in the polyphenol/flavonoid proportion and its effective antioxidant activity.

Alternative Foods in Cardio-Healthy Dietary Models That Improve Postprandial Lipemia and Insulinemia in Obese People.

Obesity is one of the major health problems worldwide. Following healthy dietary patterns can be difficult in some countries due to the lack of availability of certain foods; thus, alternative foods are needed. Our aim was to evaluate the effect of a dietary pattern consisting of fruit, avocado, whole grains, and trout (FAWGT) on postprandial insulinemia and lipemia in obese Colombian subjects.

Polyphenols from Passiflora ligularis Regulate Inflammatory Markers and Weight Gain.

Weight-related disorders affect more than half of the adult population worldwide; they are also concomitant with a state of chronic low-grade inflammation manifesting in abnormal cytokine production. The present study evaluated the effect of polyphenol and flavonoid extract from (granadilla) on low-grade inflammation and body weight in overweight Wistar rats. To induce weight-gain, rats were fed a chow diet with 30% sucrose water and supplemented with 2.

Folin-Ciocalteu Reaction Alternatives for Higher Polyphenol Quantitation in Colombian Passion Fruits.

Flavicarpa, Sims, and Juss are Colombian fruits (passion fruits) of important exportation value. They act efficiently as antioxidants, antifungal, and antimicrobial compounds due to their high polyphenol content. Polyphenols can be quantified by the Folin-Ciocalteu (F-C) reaction.

Bioelectrical impedance analysis and dual x-ray absorptiometry agreement for skeletal muscle mass index evaluation in sarcopenia diagnosis.

Background: All definitions for diagnosing sarcopenia include the estimation of muscle mass. This can be made using bioelectrical impedance analysis (BIA) or dual x-ray absorptiometry (DXA). BIA is a portable and inexpensive method suitable for clinical settings, while DXA is cumbersome, more expensive and less available.

Polyphenol Extracts from Three Colombian Passifloras (Passion Fruits) Prevent Inflammation-Induced Barrier Dysfunction of Caco-2 Cells.

Chronic intestinal inflammation is associated with pathophysiology of obesity and inflammatory bowel diseases. Gastrointestinal inflammation increases barrier dysfunction exacerbating the immune response and perpetuating chronic inflammation. Anti-inflammatory flavonoids may prevent this intestinal barrier dysfunction.

Provisional cut-off points for the diagnosis of sarcopenia in elderly people from Caldas (Colombia).

Introduction: Sarcopenia is defined as a decrease in muscle mass associated with the reduction of performance and physical function. It is an indicator of adverse outcomes in elderly people. Its diagnosis requires body composition data of healthy young population to establish reference values of low muscle mass.

Looking for optimum ECG electrodes for bioelectrical impedance analysis (BIA). The need for evaluation.

Background: The accuracy and precision of the BIA method is affected by the electrode system. Failing to adjust for differences in it may result in systematic biases of up to 5.2%.
