Body-composition analysis using bioelectrical impedance analysis is gradually becoming more widely used in clinical practice. The ratio of extracellular water (ECW) to total body water (TBW) is thought to be related to the prognosis of a variety of diseases. However, its performance in people with advanced cancer deserves further discussion. ⋯ We found that in people with cancer, an ECW/TBW ≥ 0.40 was a risk factor for malnutrition and lower health-related quality of life, and in people with advanced cancer, it was a risk factor for poor prognosis.

Fibroblast growth factor 23 (FGF23) controls the production and degradation of biologically active vitamin D, 1,25(OH)2D3, and phosphate reabsorption in the kidney as a hormone synthesized by bone cells. Additional paracrine effects in other organs exist as well. As a biomarker, the FGF23 plasma concentration increases in renal and cardiovascular diseases, and is correlated with outcome. The regulation of FGF23 is incompletely understood and dependent on several factors, including oxidative stress. L-homocysteine is an amino acid produced in methionine metabolism, and can be converted into further metabolites depending on the availability of vitamin B. Hyperhomocysteinemia is a potential cardiovascular risk factor. Our study aimed to explore whether homocysteine impacts FGF23 synthesis. ⋯ Homocysteine is a potent stimulator of FGF23 production, an effect at least in part mediated by oxidative stress. The homocysteine-dependent upregulation of FGF23 presumably contributes to its role as a cardiovascular risk factor.

Child undernutrition is a major public health problem. Globally in 2020, 149 million children <5 y of age were estimated to be stunted (too short for age), 45 million to be wasted (too thin for height), and 38.9 million were overweight. The aim of this review was to examine previous studies to determine the factors associated with malnutrition and contribute to the existing body of evidence needed for the formulation of effective interventions. ⋯ The most consistent factors associated with child malnutrition were maternal education, household income, maternal nutritional status, age of the child, availability of sanitation facility at home, size of family, birth order in the family, and child's birth weight. Breastfeeding and caring practices, cooking area and the fuel used, sex, and socioeconomic status of the children also contribute toward child malnutrition.

Probiotics and their food sources, prebiotics, are known to have qualities that help with gastrointestinal issues along with overall improvement in health and well-being. Pro- and prebiotics play a key role in neuroimmune processes. Their beneficial effects on health are linked to interactions of the gastrointestinal tract, immune system, and neurologic systems. ⋯ Nutrition has the potential to increase psychological well-being and could be used much as are psychiatric drugs. Probiotics and prebiotics have evolved as promising therapeutic techniques to treat several disease conditions associated with the gastrointestinal tract. The aim of this review was to provide useful information about the use of probiotics and prebiotics in mitigation of various diseases such as COVID-19, congenital heart disease, diarrhea, inflammatory bowel disease, hypertension, genitourinary tract infection, colon cancer, immune system defense, mineral absorption, allergic disorders, and atopic dermatitis.

Randomized Controlled Trial
Prickly pear juice consumption after fat intake affects postprandial heart rate variability but not traditional risk factors of cardiovascular disease in healthy men.
Prickly Pear (PP) fruit is proposed to have anti-atherosclerotic and anti-hyperglycemic effects. The aim of this study was to examine the effects of a single consumption of PP juice on modifiable blood and physiological markers of cardiovascular disease risk in healthy men using a postprandial hyperlipidemia model. ⋯ Consumption of PP (with high-fat muffin), did not alter traditional cardiovascular disease risk responses but rather markers of HRV, beyond an expected increase in glucose attributed to the carbohydrate content of the trials foods. Additionally, macronutrient content is important when understanding HRV responses to meals.
