AIMS: European and American guidelines have recommended salt and fluid restriction for patients with chronic heart failure (CHF) despite scarce scientific evidence. Therefore, we investigated the effects of salt and fluid restriction in patients with CHF. METHODS AND RESULTS: Ninety-seven stable patients in NYHA class II-IV, on optimal medication, with previous signs of fluid retention, [...]
Occurrence of dynamic left ventricular outflow tract (LVOT) obstruction is not infrequent in critically ill patients, and it is associated with potential danger. Here, we report a case of transient heart failure with hemodynamic deterioration paradoxically induced by extreme dehydration. This article describes clinical features of the patient and echocardiographic findings of dynamic LVOT obstruction [...]
Water is essential for health and vital for all bodily functions. If water losses are not replaced then dehydration can occur and even mild dehydration is associated with negative effects on health including impaired cognitive function. Studies in schoolchildren have found that many are arriving at school with a hydration deficit and, once they arrive, [...]
This study compared erythrocyte changes between a group of subjects with sickle cell trait (SCT) and controls (subjects without hemoglobinopathy) during a soccer game in two conditions: with and without hydration. Erythrocyte deformability of subjects was assessed by the coefficient of erythrocyte rigidity (Tk) which was calculated before and after football match. Our results showed [...]
Background/objectives: In sedentary adults, hydration is mostly influenced by total fluid intake and not by sweat losses; moreover, low daily fluid intake is associated with adverse health outcomes. This study aimed to model the relation between total fluid intake and urinary hydration biomarkers.Subjects/methods:During 4 consecutive weekdays, 82 adults (age, 31.6±4.3 years; body mass index, 23.2±2.7 kg/m(2); [...]
Dehydration and hyperthermia reduces leg blood flow (LBF), cardiac output([Formula: see text]) and arterial pressure during whole-body exercise. It is unknown whether the reductions in blood flow are associated with dehydration-induced alterations in arterial blood oxygen content (C aO2) andO2-dependent signaling. This study investigated the impact of dehydration and concomitant alterations in C aO2 upon [...]
We assessed the urinary indexes of hydration status of Greco-Roman wrestlers in an authentic precompetition situation at the time of official weigh-in (OWI). A total of 51 of 89 wrestlers competing in the Estonian Championship in 2009 donated a urine sample. Questionnaire responses revealed that 27 wrestlers (body mass losers (BMLs)) reduced body mass before [...]

Water, an essential nutrient, is often ignored in reports of dietary surveys and nutrition. Although it is ubiquitous in foods and beverages, the attention is often focused on the minerals or calorific values of the fluids imbibed rather than the water per se. Water is often taken for granted by many in Western countries due [...]
Provision of appropriate nutrition and hydration is a hallmark of compassionate care but is often neglected in all types of healthcare.1 2 3 4 5 These problems are not new and have been reported in the medical literature for nearly four decades.6 7 The consequences are clinically and financially costly. The estimated excess UK health [...]
