Filter by:This is a descriptive mixed method pilot study to determine the feasibility of a tailored nurse-delivered telephone intervention designed to impact mucositis symptom severity and prevent dehydration in lung and head/neck cancer patients undergoing chemoradiation, therefore reducing overall symptom severity and improving quality of life. Secondary purposes for this study are to investigate if the nursing intervention can decrease lung and head/neck cancer patients' unscheduled medical visits between chemoradiation treatments.
After partial nephrectomy, kidney function decreases by about 10% overall and by about 20% in the operated kidney. This is primarily due to the loss of healthy parenchymal volume during resection of the tumor. In an effort to preserve and regenerate healthy parenchyma during the procedure and ultimately renal function after partial nephrectomy, the single center double arm single-blinded randomized screening clinical trial will evaluate the ability of human amnion/chorion allograft to facilitate the recovery of renal function following robotic partial nephrectomy.
The objective of this randomized clinical study was to evaluate the use of dehydrated human amnion-chorion membrane as an exposed barrier for guided bone regeneration (GBR) after tooth extraction and to determine whether intentional exposure of this membrane to the oral environment compromises ridge dimensions and bone vitality for implant placement.
The mechanism(s) by which dehydration (both intra- and extracellular) impairs performance are still poorly described. A loss of volume results in increased occurrence of orthostatic intolerance, including dizziness, fatigue, headaches and related symptoms with upright posture. Any of these symptoms can contribute to decreased performance in maneuvers performed in the upright posture, which includes many military tasks. Thus, loss of volume challenges the cardiovascular and blood pressure responses to systemic whole body endurance exercise, while osmolality is the stimulus for intracellular dehydration that may impair local muscle force production by impairing contractile function, neural signaling, or both. In this study, we will compare how both types of dehydration affect MSNA and CAC. The results of this study will provide mechanistic insight for how dehydration (intra- or extracellular) impairs systemic whole body and local small muscle performance in vivo. This Basic Science study seeks to understand how volume and osmolality impact MSNA and CAC as a basis for improving potential countermeasures, such as a more optimally formulated rehydration beverage. Therefore, this study directly complements Task Area T10 (Hot Weather Operations and Hydration: Injury and Performance Optimization) and impacts virtually all 14 Military Operational Medicine Research Program Drivers.
Monitoring of a person's physical status is a key point for maintaining of "healthy life". Wearable devices provide a unique possibility for real-time monitoring. This study aims to estimate the accuracy of Spectrophon Dehydration Body Monitor (DBM) incorporated in smartwatch Samsung Gear S2 and sport band Samsung Gear Fit2 by comparing data obtained by DBM with the total weight lost during exertion.
The purpose of the study is to determine whether participants who are dictating their own administration of IV fluid boluses in response to thirst, receive better protection from hypovolaemia and volume overload than those who undergo routine fluid management. Thirst is prominent in critically ill patients and is related to dehydration. In a recent study of the symptoms experience in ITU patients at high risk of dying, the sensation of thirst was reported in 70.8% of assessments made and was considered to be one of the most intense stressors. Thirst and dehydration can be combated in an ITU setting by consuming oral fluids and through administration of intravenous fluids. However, in older adults, frailty and dysphagia reduces patients' capability to access fluid and results in thirst. In addition, the administration of IV fluids is determined by the attending physician and is often only re-evaluated on a daily or twice-daily basis. The Quench machine has been designed to allow the patient to have more control over their oral and IV fluid administration protocol. This may help reduce the sensation of thirst and dehydration in patients. The machinery is an automated fluid delivery system that will administer a given bolus of IV fluid in response to a trigger provided by the patient. The purpose of the current study is to examine the physiological basis for the functional benefit of this Quench system by investigating the effectiveness of the thirst response in healthy humans as a guide for administration of intravenous fluid boluses. To explore this, the investigators have designed a randomised, cross-over study. On one visit IV fluid boluses will be administered as per the participants' request in response to thirst. In the second arm of the study participants will be administered routine IV fluid maintenance as per NICE guidelines. Body mass at the end of a 4 hour fluid administration intervention will be our primary research outcome and will be compared between the two arms of the study. From this comparison the investigators hope to show that a patient would be able to accurately manage their level of hydration, both in terms of correcting dehydration and avoiding fluid overload. It is thought that avoiding states of fluid imbalance can reduce post surgical recovery times, reduce the incidence of post operative complications and avoid critical complications of fluid imbalance, such as acute kidney injury.
BACKGROUND: Prior research has shown a relationship between dehydration, falls and pulmonary aspiration among older adults in nursing and health care facilities, which contributes to its loss of independence and quality-of-life. Is believed that improving communication among health professional decreases the number of adverse events in institutionalized patients. This study will evaluate the feasibility of a set of sign displays designed to communicate fall, dehydration and pulmonary aspiration risks and will reflect on tailored interventions to manage these events in nursing homes. METHODS AND ANALYSIS: This will be a national, single-center, feasibility study. All patients, with chronic neurologic diseases selected from a nursing home, will be invited to participate. At baseline patients will undertake a screening risk assessment and it will be attributed a correspondent risk display. Study duration will be a minimum of 3 months per participant, including daily record of events and monthly interview assessments. Events data will be compared with historical data extracted retrospectively from medical and nursing charts.
The purpose of the study is assessment of volume status by bedside ultrasound in children with acute gastroenteritis
The purpose of the study is to determine serum inflammatory adhesion molecules levels in hyperemesis gravidarum
During exercise in the heat, there is a need to replenish fluids in order to avoid dehydration and decrease the risk for heat illness. What drives this urge to drink is the thirst mechanism. Following ingestion of fluids, there is an inhibition of thirst before there is a replenishing of fluids. However, there is little scientific evidence of where thirst is inhibited, if this thirst inhibition is augmented by exercise and how thirst itself influence exercise performance. Further, during rehydration studies, it is very difficult to successfully blind a subject to their drinking/hydration protocol. Previous studies that have blinded a subject to their drinking have used various methods such as intravenous fluid administration and/or nasogastric tubes. Therefore, the purpose of this research is to examine the mechanistic roles thirst inhibition plays while exercising in the heat while undergoing intravenous fluid administration. Specific attention will be directed to the cardiovascular and thermoregulatory function of the individuals. All blood, cardiovascular, thermoregulatory, and perceptual measures are shown in the diagram below.
