DeHydration: Assessing Kids Accurately
Severe DehydrationDiarrhea is the second leading cause of death in children worldwide, and accurately assessing dehydration status remains a crucial step in preventing morbidity and mortality from this disease. While children with severe dehydration require immediate treatment with intravenous fluids, children with mild to moderate dehydration have a significant reduction in hospital length of stay and fewer adverse events when treated with relatively inexpensive oral rehydration solution (ORS). While several clinical scales have been developed for assessing dehydration in children, these scales have never been prospectively validated in a low-income country setting, where the vast majority of diarrhea morbidity and mortality occurs in children. The investigators hypothesize that new clinical and ultrasound-based tools will improve the diagnosis of severe dehydration in children with diarrhea in low-income countries, reducing the morbidity and mortality that occurs as a result of under-diagnosis of severe dehydration as well as the adverse events and inappropriate utilization of scarce resources that occurs as a result of over-diagnosis of severe dehydration.
Biomarkers for Noninvasive Assessment of Human Hydration
DehydrationLow levels of dehydration (the loss of body water corresponding to 2% of the body weight), deteriorate physical and cognitive performance and may also be linked to a number of chronic diseases. The standard test used for the assessment of hydration status is plasma osmolality. This blood test is invasive, requires time and laboratory equipment and is not accurate for isotonic dehydration. The goal of this project is to determine whether a new molecular technology, saliva-based Stress Response Profiling (SRP) biomarkers, could be used for non-invasive diagnostics of dehydration.
The Absorption Rate of Subcutaneous Infused Fluid
Aged75 and Over4 moreThe purpose of the study is to examine the rate of absorption of subcutaneous infused fluid in older adults when acutely ill compared to when they are not acutely ill.
Continuous Enteral Rehydration by Nasogastric Tube With ORS in Children With Acute Gastroenteritis...
Acute GastroenteritisDehydrationWhen oral rehydration is impossible, enteral rehydration via the nasogastric route has been the recommended method of rehydration since 2008 by ESPGHAN ( European Society for Paediatric Gastroenterology Hepatology and Nutrition ), for children with acute gastroenteritis. However, these recommendations are rarely followed in France. These recommendations were not applied in the Children's Emergency Department of BREST University Hospital. The investigators changed the protocol and shared it with the caregivers of the emergency unit. The investigators studied the impact of this change of protocol
Effects of Amino Acid/Electrolyte-based Beverages on Hydration Status
DehydrationOlder adults typically do not drink later in the day to avoid the necessity of interrupting sleep to urinate. Sometimes they also limit ingestion of fluids to avoid the need to urinate when engaged in certain activities such as traveling or attending an event. Therefore, beverages that have greater fluid retention in the body leading to a more sustained positive hydration status could be advantageous in such situations. The composition of a beverage as well as other factors such as volume ingested and metabolism of components can affect the retention of the fluid in the body. Age may be another factor. The beverage hydration index (BHI), first described in 2016, was used to indicate the hydration response to thirteen well-known beverages in young male adults. The current study assesses the BHI of four beverages and how that response is affected by age following the standardized protocol. The four beverages have been chosen for inclusion in this study because they have been used by older adults to prevent dehydration.
Tap Water Intake and Perceptions in US Latinx Adults
DehydrationThe purpose of this exploratory cross-sectional investigation is to evaluate associations between tap water perceptions, water consumption behaviors, and hydration status in Latinx adults (18 - 65 y). The objective is to identify perceptual determinants that explain the associations between tap water avoidance and plain water intake and hydration status in Latinx adults. Aim 1: Characterize the degree to which individual- and community-level factors uniquely predict the perception that tap water is not safe in Latinx adults. Aim 2: Evaluate household income, education level, and US nativity as potential moderators of the associations between predictors and perceptions of tap water safety. Aim 3: Evaluate the influence of tap water safety perceptions on plain water intake and 24-h hydration status, after adjustment for predictors of tap water safety perceptions, in a sub-sample of Latinx adults.
Validation of a Dehydration Scoring System
DehydrationThis is a study to evaluate the validity, reliability, and clinical usefulness of a new dehydration scoring system (DSS).
LifeFlow Fluid Study- Non- Critical Pediatric Patients Having a Trans Abdominal Ultrasound
Dehydration in ChildrenDehydrationThis is an unblinded, randomized control study examining two fluid delivery modalities for non-critical female patients with a planned transabdominal pelvic ultrasound requiring intravenous fluid boluses.
The Effect of Acute Mild Dehydration on Blood Pressure Control
Mild DehydrationThe goal of this project is determine how acute mild dehydration impacts blood pressure control at rest and during static exercise. This protocol will test healthy young and older adults in a normally hydrated and dehydrated condition.
Hydration Amongst Nurses and Doctors Oncall
DehydrationThe main purpose of this study is to assess and compare the hydration status of medical and nursing staff and to investigate the relationship between the hydration status, cognitive function and serum cortisol (marker of stress). We hypothesise that a significant proportion of doctors and nurses will be dehydrated at the end of their working day. Some, as in other occupations, may be dehydrated at the start of their working day. This is likely to be associated with impairment in cognitive performance at the end of the working day compared to the beginning and expected to be more pronounced after a night shift. There may be less noticeable difference amongst nursing staff given the protected break time. Dehydration and associated impairment in cognition is of important clinical value as it can impact patient care. participants will be involved in the study for two shifts (one day and one night), aiming at 15 medical and 15 surgical nurses as well as 15 medical (total 15 day and 15 night shifts from each group) and surgical doctors (total 15 day and 15 night shifts from each group). Those that do not work both day and night shifts will participate for only one shift and a new participant will be recruited until target number of shifts is achieved.
