Hypernatremia is defined as plasma Na+ concentration above 145 meq/L (often due to absolute body water loss and not to total sodium excess). Nevertheless, when kidney damage is present, as occurs in renal diseases, hepatic cirrhosis and congestive heart failure, total body sodium can be increased. The present study evaluates the relationship between hypernatremia and response to anesthetic drug...

BACKGROUND An accurate assessment of the degree of dehydration in infants and children is important for proper decision-making and treatment. This emphasizes the need for laboratory tests to improve the accuracy of clinical assessment of dehydration. The aim of this study was to assess the relationship between clinical and laboratory parameters in the assessment of dehydration. METHODS We eva...

Dehydration (body water deficit) is a physiologic state that can have profound implications for human health and performance. Unfortunately, dehydration can be difficult to assess, and there is no single, universal gold standard for decisionmaking. In this article, we review the physiologic basis for understanding quantitative dehydration assessment. We highlight how phenomenologic interpretati...

Larvae of the Antarctic midge, Belgica antarctica, routinely face periods of limited water availability in their natural environments on the Antarctic Peninsula. As a result, B. antarctica is one of the most dehydration-tolerant insects studied, surviving up to 70% loss of its body water. While previous studies have characterized the physiological effects of a single bout of dehydration, in nat...

INTRODUCTION Diarrhea remains one of the most common and most deadly conditions affecting children worldwide. Accurately assessing dehydration status is critical to determining treatment course, yet no clinical diagnostic models for dehydration have been empirically derived and validated for use in resource-limited settings. METHODS In the Dehydration: Assessing Kids Accurately (DHAKA) prospe...

Pervaporation (PV) is a well-established membrane technique used in separation; especially dehydration of organic solvents. Along with other parameters such as permeate pressure and feed temperature; feed composition is an important parameter, which affects separation characteristics and membrane performance in pervaporation. In this paper, the separation characteristics of a hydrophilic polyvi...
