Previously it was demonstrated that mineralization and alkalization properties of mineral water are important factors influencing acid-base balance and hydration in athletes. The purpose of this study was to investigate the effects of drinking different types of water on urine pH, specific urine gravity, and post-exercise lactate utilization in response to strenuous exercise. Thirty-six male soccer players were divided into three intervention groups, consuming around 4.0 l/day of different types of water for 7 days: HM (n=12; highly mineralized water), LM (n=12; low mineralized water), and CON (n=12; table water)...

OBJECTIVE: This prospective study uses calf bioimpedance spectroscopy (cBIS) to guide the attainment of dry weight (DWcBIS) in chronic hemodialysis (HD) patients. The primary aim of this study was to evaluate whether body composition is altered when fluid status is reduced to DWcBIS. METHODS: Target post-HD weight was gradually reduced from baseline (BL) until DWcBIS was achieved. DWcBIS was defined as the presence of both flattening of the curve of extracellular resistance and the attainment calf normalized resistivity in the normal range during the dialysis treatment...

OBJECTIVES: To assess and correlate changes in body composition and haemodynamic function during pregnancy. To identify different haemodynamic profiles based on the onset of hypertensive diseases such as gestational hypertension and preeclampsia. METHODS: We enrolled 265 healthy, normotensive pregnant women throughout pregnancy (from 6+0 to 36+0weeks). They were subjected to assessment of body composition and haemodynamic function using non-invasive methods. We divided our population in three groups: group A with physiological pregnancy, group B with gestational hypertension and group C with preeclamptic patients...

OBJECTIVE: Simplified methods to estimate lean body mass (LBM), an important nutritional measure representing muscle mass and somatic protein, are lacking in nondialyzed patients with chronic kidney disease (CKD). We developed and tested 2 reliable equations for estimation of LBM in daily clinical practice. DESIGN AND METHODS: The development and validation groups both included 150 nondialyzed patients with CKD Stages 3 to 5. Two equations for estimating LBM based on mid-arm muscle circumference (MAMC) or handgrip strength (HGS) were developed and validated in CKD patients with dual-energy x-ray absorptiometry as referenced gold method...

Human beings are constituted mainly of water. In particular, children's total body water might reach 75-80% of their body weight, compared to 60-70% in adults. It is therefore not surprising, that children, especially hospitalized newborns and infants, are markedly prone to water and electrolyte imbalances. Parenteral fluid therapy is a cornerstone of medical treatment and is thus of exceptional relevance in this patient population. It is crucial to appreciate the fact that intravenous fluids are drugs with very different characteristics, different indications, contraindications and relevant side effects...

This secondary data analysis addressed gaps in knowledge about effects of chronic water intake. Longitudinal data from the Adapt Study were used to describe effects of prescribing a sustained increase in water intake relative to baseline, for 4 weeks, on multiple indices of total body water (TBW) flux, regulation, distribution, and volume in five healthy, free-living, young men, with mean total water intake initially below 2 L/day. Indices were measured weekly. Within-person fixed effect models tested for significant changes in indices over time and associations between changes in indices...

The wood frog (Rana sylvatica) can endure freezing of up to 65% of total body water during winter. When frozen, wood frogs enter a dormant state characterized by a cessation of vital functions (i.e., no heartbeat, blood circulation, breathing, brain activity, or movement). Wood frogs utilize various behavioural and biochemical adaptations to survive extreme freezing and component anoxia and dehydration stresses, including a global suppression of metabolic functions and gene expression. The stress-responsive myocyte enhancer factor-2 (MEF2) transcription factor family regulates the selective expression of genes involved in glucose transport, protein quality control, and phosphagen homeostasis...

BACKGROUND: In obesity, low levels of vitamin D (VD) and vitamin B12 (VB12), may be the result of different pathophysiological mechanisms, but the possible association between them has not yet been defined. The aim of this cross-sectional analysis was to investigate the possible relationship between serum 25-hydroxyvitamin D (25(OH)D) and VB12 levels in middle aged women. METHODS: In 80 women, we indirectly evaluated body composition and body volumes [extracellular fluid volume (ECV) and total body water (TBW)] by anthropometric and bioelectrical impedance analysis...

BACKGROUND: Excessive adipocyte growth during the pubertal transition predisposes to the development and persistence of obesity in adulthood. Visceral accumulation of body fat is particularly disadvantageous when it is correlated with insulin resistance, secondary hyperinsulinaemia, dysglicaemia, and atherogenic dyslipidemia. OBJECTIVES: The aim of this study was to conduct a nutritional status assessment and body composition analysis in 13-year-old adolescents of both genders with visceral fat accumulation (WC ≥ 90th percentile) and different BMI values...

This paper describes a method to estimate interstitial fluid volume and peripheral blood volume (BVP) in hemodialysis (HD) patients using whole body (wBIS) and calf (cBIS) bioimpedance spectroscopy techniques. The aim of this study was to evaluate the usefulness of the technique. Thirty five HD patients were studied pre and post HD. Extracellular volume (ECV) and total body water (TBW) were measured using wBIS and cBIS. The calf resistances at 5 kHz (R5) and at 1000 kHz (R1000) respectively reflect ECV and TBW in the calf...

BACKGROUND: The side effects of radiotherapy (RT) and the occurrence of comorbidity often result in appetite loss in patients, which leads to serious nutritional problems, significantly affecting the patients' treatment results and disease prognosis. OBJECTIVES: We aimed to investigate changes in the body composition of patients with cancer from the time they received RT to 3 months after completion of RT. DESIGN: A total of 101 cancer patients who received RT, which included head or neck cancer, chest or breast cancer, and abdominal or pelvic cancer patients...

RATIONALE: The doubly labelled water (DLW) method is the reference method for the estimation of free-living total energy expenditure (TEE). In this method, where both (2) H and (18) O are employed, different approaches have been adopted to deal with the non-conformity observed regarding the distribution space for the labels being non-coincident with total body water. However, the method adopted can have a significant effect on the estimated TEE. METHODS: We proposed a Bayesian reasoning approach to modify an assumed prior distribution for the space ratio using experimental data to derive the TEE...

When the doubly-labeled water (DLW) method is used to measure total daily energy expenditure (TDEE), isotope measurements are typically performed using isotope ratio mass spectrometry (IRMS). New technologies, such as off-axis integrated cavity output spectroscopy (OA-ICOS) provide comparable isotopic measurements of standard waters and human urine samples, but the accuracy of carbon dioxide production (VCO2) determined with OA-ICOS has not been demonstrated. We compared simultaneous measurement of VCO2 obtained using whole-room indirect calorimetry (IC) with DLW-based measurements from IRMS and OA-ICOS...

Adequate fluid management is an important therapeutic goal of dialysis. Recently, bioelectrical impedance methods have been used to determine body fluid status, but pediatric reports are rare. To determine the accuracy of bioelectrical impedance methods in the assessment of body fluid statusof children undergoing hemodialysis (HD), 12 children on HD were studied. A multi-frequency bioimpedance analysis device (Inbody S10) and bioimpedance spectroscopy device (BCM) were used to evaluate fluid status. Fluid removal during a HD session (assessed as body-weight change, ΔBWt) was compared with the difference in total body water determined by each device (measured fluid difference, ΔMF), which showed strong correlation using either method (Pearson's coefficient, r = 0...

Cardiac rehabilitation (CR) is the standard procedure in persons after coronary artery bypass grafting (CABG). Its basic aim is to combat coronary heart disease (CHD) risk factors through physical activity and normalization of body mass. Many authors highlight the differences in response to training in CR as dependent on gender, age and occurrence of accompanying disease. The aim of this study is to assess the effectiveness of a three-week early CR in reference to changing body composition parameters in patients over 50 years of age...

Rana sylvatica, known as the wood frog, can survive extremely cold temperatures during winter by undergoing full-body freezing, where it tolerates freezing of 65-70% of its total body water. During freezing, cellular dehydration decreases damage to the cell by preventing ice crystallization. Challenged with many stresses, these animals are forced to develop physiological adaptations to osmoregulation and osmoprotection that are necessary to ensure their survival. The purpose of this study was to elucidate a potential mechanism by which the transcription factor, NFAT5, regulates the expression of three osmoregulatory proteins (aldose reductase, SMIT, and BGT-1)...

Diabetic ketoacidosis (DKA) is a critical complication of type 1 diabetes associated with water and electrolyte disorders. Here, we report a case of DKA with extreme hyperkalemia (9.0 mEq/L) in a patient with type 1 diabetes on hemodialysis. He had a left frontal cerebral infarction resulting in inability to manage his continuous subcutaneous insulin infusion pump. Electrocardiography showed typical changes of hyperkalemia, including absent P waves, prolonged QRS interval and tented T waves. There was no evidence of total body water deficit...

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is an active form of nonalcoholic fatty liver disease. Risk factors for NASH include type 2 diabetes mellitus (T2DM) and obesity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors used to treat T2DM prevent glucose reabsorption in the kidney and increase glucose urinary excretion. Dapagliflozin is a potent, selective SGLT2 inhibitor that reduces hyperglycemia in patients with T2DM and has been demonstrated to reduce some complications associated with NASH in rodent models...
