OBJECTIVE   To present evidence-based recommendations that promote optimized fluid-maintenance practices for physically active individuals. BACKGROUND   Both a lack of adequate fluid replacement (hypohydration) and excessive intake (hyperhydration) can compromise athletic performance and increase health risks. Athletes need access to water to prevent hypohydration during physical activity but...

in this paper, a finite element model is developed for the fully hydro-mechanical analysis of hydraulic fracturing in partially saturated porous media. the model is derived from the framework of generalized biot theory. the fracture propagation is governed by a cohesive fracture model. the flow within the fracture zone is modeled by the lubrication equation. the displacement of solid phase, and...

We apply fluid-replacement logging in arsenic-contaminated regions of Bangladesh using a low-cost, down-well fluid conductivity logging tool to detect leaks in the cased section of wells. The fluid-conductivity tool is designed for the developing world: it is lightweight and easily transportable, operable by one person, and can be built for minimal cost. The fluid-replacement test identifies le...

OBJECTIVE To present recommendations to optimize the fluid-replacement practices of athletes. BACKGROUND Dehydration can compromise athletic performance and increase the risk of exertional heat injury. Athletes do not voluntarily drink sufficient water to prevent dehydration during physical activity. Drinking behavior can be modified by education, increasing accessibility, and optimizing pala...

Often, too little consideration is given to the fluids used in all forms of continuous renal replacement therapy (CRRT). However, errors in fluid prescription, delivery, or creation can be rapidly fatal; in addition, fluid associated expenses can be the overriding cost in continuous renal replacement therapies. While a standard solution is frequently acceptable in most clinical circumstances, s...

Replacement dolomite in the Latemar carbonate buildup developed when limestone was infiltrated by reactive fluid. Minor-element, trace-element, and oxygen and carbon isotope compositions of dolomite and precursor limestone constrain the origin of the fluid and fundamental aspects of the flow. Inferred salinity (similar to seawater); temperature (45°–85°C); Sr/Sr (0.7076–0.7079); Ca/Mg (<1.4); a...

OBJECTIVES Acute kidney injury and fluid overload frequently necessitate initiation of continuous renal replacement therapy in critically ill patients admitted to the ICU. In this study, our primary objective was to determine the effect of timing of initiation of continuous renal replacement therapy on ICU mortality in children requiring renal support for management of acute kidney injury and/o...

between CVP and indexes of fluid responsiveness might be influenced by ongoing fluid losses or gains that were not necessarily easily measurable. Finally, in many clinical situations, the success or failure of fluid resuscitation measures is not determined by preset goals in terms of cardiac output or other indexes of cardiac performance but by criteria such as pressor requirements or blood lac...
