#1
REVIEW
Nicholas Jourjine
In animals, nervous systems regulate the ingestion of food and water in a manner that reflects internal metabolic need. While the coordination of these two ingestive behaviors is essential for homeostasis, it has been unclear how internal signals of hunger and thirst interact to effectively coordinate food and water ingestion. In the last year, work in insects and mammals has begun to elucidate some of these interactions. As reviewed here, these studies have identified novel molecular and neural mechanisms that coordinate the regulation of food and water ingestion behaviors...

Exercise-associated hyponatremia (EAH) was initially described in the 1980s in endurance athletes, and work done since then has conclusively identified that overdrinking beyond thirst and non-osmotic arginine vasopressin release are the most common etiologic factors. In recent years, EAH has been described in a broader variety of athletic events and also has been linked to the development of rhabdomyolysis. The potential role of volume and sodium depletion in a subset of athletes has also been described. This review focuses on the most recent literature in the field of EAH and summarizes key new findings in the epidemiology, pathophysiology, treatment, and prevention of this condition...

The population of elderly individuals is increasing worldwide. With aging, various hormonal and kidney changes occur, both affecting water homeostasis. Aging is a risk factor for chronic kidney disease (CKD) and many features of CKD are reproduced in the aging kidney. Dehydration and hyperosmolarity can be triggered by diminished thirst perception in this population. Elderly with dementia are especially susceptible to abnormalities of their electrolyte and body water homeostasis and should be (re-)assessed for polypharmacy...

Gitelman syndrome (GS) is the most frequently inherited renal salt-wasting tubulointerstitial disease. It follows variable but usually asymptomatic benign course. We present a rare case of GS that remained clinical enigma. A 22-year male presented with severe episodic fatigue involving all limbs associated with episodes of sinking, palpitations, salt craving, increased thirst and frequent micturition hampering his routine daily activities. Laboratory workup revealed serum potassium, 2.7 mmol/L, serum magnesium, 0...

Thousands of Eritreans flee their homes each month, embarking on dangerous journeys. With these extreme life experiences in mind, this qualitative study aimed to better understand Eritrean resettled refugees' perceptions of United States (US) preventive health care through the lens of the Life Course Theory. Through secondary thematic analysis of narrative data, two over-arching themes emerged: 1) a thirst for information, understanding and affordable health care and 2) attitudes of gratitude and hope despite lack of information and funding...

Hyponatremia is common in chronic kidney disease and in end stage kidney disease (ESKD) but hypernatremia is infrequent in ESKD. The incidence of hypernatremia is higher in ambulatory peritoneal dialysis (PD) than in hemodialysis (HD) patients. In PD patients it is often a result of excessive ultrafiltration but in HD it is often a result of dialysate composition errors. Dialysate composition errors can inadvertently cause either hyponatremia or hypernatremia. We present two cases of symptomatic hypernatremia which manifested as increased thirst, excessive weight gain and worsening hypertension in HD patients...

REVIEW
Denovan P Begg
During heat waves, significant mortality and morbidity occurs in elderly populations due to heat-stress and dehydration. The dehydration is primarily attributable to inadequate water intake caused by dysfunction of the central nervous system mechanisms controlling thirst. The phenomenon of a reduced thirst in response to dehydration in aging was first observed decades ago and has been examined extensively since. The reduced thirst and ingestive behavior have been reported consistently in response to hyperosmotic stimuli, hypovolemic stimuli and dehydration in both elderly humans and animal models of aging...

Herod the Great was appointed "king of Jews," to govern Judea, by the Roman Emperor and Senate. He lived from 73/74 BCE to 4 CE. He died with an illness and symptoms that have been the source of considerable speculation. Richard Strauss depicted Herod in his classic opera, "Salome." That opera was derived from a play of the same name by Oscar Wilde, which was based on an 1876 painting, "Salome Dancing Before Herod," by Gustave Moreau. The operatic Herod was afflicted with an illness characterized by dementia, hallucinations, paranoia, alcoholism (from drinking the Emperor's wine), violence, twitches, and sterility; different interpretations showed him also with falls, chills, shaking, thirst, forgetfulness, and sleepiness, for which we suggest the novel diagnosis of chronic lead intoxication (which can manifest to rheumatologists as saturnine gout)...

Objective Routine fasting (12 h) is always applied before laparoscopic cholecystectomy, but prolonged preoperative fasting causes thirst, hunger, and irritability as well as dehydration, low blood glucose, insulin resistance and other adverse reactions. We assessed the safety and efficacy of a shortened preoperative fasting period in patients undergoing laparoscopic cholecystectomy. Methods We searched PubMed, Embase and Cochrane Central Register of Controlled Trials up to 20 November 2015 and selected controlled trials with a shortened fasting time before laparoscopic cholecystectomy...

In the pivotal TEMPO 3:4 trial, the arginine vasopressin V2-receptor antagonist tolvaptan reduced the rate of kidney growth in patients with autosomal dominant polycystic kidney disease. Tolvaptan was initiated as daily morning/afternoon doses of 45/15 mg, and uptitrated weekly to 60/30 mg and 90/30 mg according to patient-reported tolerability. The current report describes 3 phase 2 trials in adult autosomal dominant polycystic kidney disease subjects that were the basis for the titrated split-dose regimen: a single ascending-dose trial (tolvaptan 15 to 120 mg; n = 11), a multiple split-dose trial (tolvaptan 15/15 mg, 30/0 mg, 30/15 mg, and 30/30 mg; n = 37), and an 8-week open-label safety and efficacy trial in 46 of the 48 subjects who participated in the prior 2 trials (tolvaptan 30/15 mg, 45/15 mg, 60/30 mg, and 90/30 mg)...

INTRODUCTION: Healthcare professionals tend to consider common non-alarming drug-related symptoms to be of little clinical relevance. However, such symptoms can have a substantial impact on the individual patient. Insight into patient-reported symptoms could aid pharmacists to identify improvements in medication treatment, for instance in the patient interview at the start of a clinical medication review (CMR). OBJECTIVE: The objectives of this study were to describe the numbers and types of patient-reported symptoms assessed during a CMR and to elucidate their potential association with the drugs in use...

BACKGROUND: This is an updated review originally published in 2004 and first updated in 2007. This version includes substantial changes to bring it in line with current methodological requirements. Methadone is a synthetic opioid that presents some challenges in dose titration and is recognised to cause potentially fatal arrhythmias in some patients. It does have a place in therapy for people who cannot tolerate other opioids but should be initiated only by experienced practitioners. This review is one of a suite of reviews on opioids for cancer pain...

REVIEW
Yong-Lim Kim, Wim Van Biesen
Volume management in peritoneal dialysis patients is of importance, as both volume overload and dehydration are associated with worse outcomes. When assessing volume status, it is important to understand that different techniques measure different fluid compartments (intracellular vs extracellular vs circulating volume) and the impact of cardiac function. Attention to salt restriction and diuretics can help to maintain euvolemia without need for hypertonic bags. Glycaemia should be monitored to avoid thirst...
