BACKGROUND Non-invasive methods for detecting water-loss dehydration following acute stroke would be clinically useful. We evaluated the diagnostic accuracy of multi-frequency bioelectrical impedance analysis (MF-BIA) against reference standards serum osmolality and osmolarity. MATERIAL AND METHODS Patients admitted to an acute stroke unit were recruited. Blood samples for electrolytes and os...

Sir, The recent article by Marcos et al. raises serious concerns about the current dosing recommendations for telavancin. The retrospective nature of their study (as the authors acknowledge) prevents direct attribution of the observed acute kidney injury (AKI) events to the use of telavancin. However, their findings regarding a link between high body mass index (BMI) and AKI are not entirely un...

A multistage ultraendurance triathlon over five times the Ironman distance within five consecutive days leads in one ultraendurance triathlete to minimal changes in body mass (BM; -0.3 kg), fat mass (FM; -1.9 kg), skeletal muscle mass (SM; no change), and total body water (TBW; +1.5 l). This might be explained by the continuously slower race times throughout the race every day and the positive ...

The aim of this study was to assess the prevalence of malnutrition-inflammation complex syndrome (MICS) and determine sensitivity and specificity of MICS markers in hemodialysis (HD) patients depending on volume status. The study included 124 patients undergoing adequate HD. The patients were distributed based on IDWG (interdialytic weight gain)/DBW (dry body weight) and IDWG/ TBW (total body w...

The frontal bone window (FBW) is a promising approach in evaluating the anterior cerebral artery. The goal of the present study was to determine the rates of detection of the basal cerebral arteries by using the FBW alone and a combination of the FBW with the temporal bone window (TBW) in 163 patients. The combined application improved detection rates of A1 (58.6% versus 46.0%, P = .001) and A2...

PURPOSE OF THE RESEARCH Bioelectrical impedance is a non-invasive technique for the assessment of body composition; however, information on its accuracy in the very old (80+years) is limited. We investigated whether the association between the impedance index and total body water (TBW) was modified by hydration status as assessed by haematocrit and serum osmolarity. MATERIALS AND METHODS This...

Na(+) loading without Cl(-) fails to increase blood pressure in the DOCA model. We compared the changes in the total body (TB) effective Na(+), K(+), Cl(-), and water (TBW) content as well as in intracellular (ICV) or extracellular (ECV) volume in rats receiving DOCA-NaCl, DOCA-NaHCO(3), or DOCA-KHCO(3). We divided 42 male rats into 5 groups. Group 1 was untreated, group 2 received 1% NaCl, and...

BACKGROUND Hypervolemic hypernatremia is caused by an increase in total exchangeable Na(+) and K(+) in excess of an increment in total body H(2)O (TBW). Unlike patients with hypovolemic or euvolemic hypernatremia, treatment needs to be targeted at correcting not only the elevated plasma Na(+) concentration, but also there is an additional requirement to achieve negative H(2)O balance to correct...

Detailed understanding of a possible decoupling between climatic drivers of plant productivity and the response of ecosystems vegetation is required. We compared trends in six NDVI metrics (1982-2010) derived from the GIMMS3g dataset with modelled biomass productivity and assessed uncertainty in trend estimates. Annual total biomass weight (TBW) was calculated with the LINPAC model. Trends were...

Placental growth is a strong predictor of fetal growth, but little is known about maternal predictors of placental growth in malnourished populations. Our objective was to investigate in a prospective study the associations of maternal weight and body composition [total body water (TBW) estimated by bioelectrical impedance and fat and fat-free mass derived from upper arm fat and muscle areas (U...
