The authors present a case of a 45-year-old man who was found dead on the grounds of an abandoned military base. His body was discovered lying face down in a large pool of partially desiccated blood with signs of having been dragged. On-site examination revealed severe injuries to the face, neck and head, the result of having been attacked by a pack of dogs. A multi-disciplinary approach, inclu...
There is ample evidence that incentive-pay structures, such as tournaments, result in increased performance. Is this due to selection or increased individual effort, and is any increased individual effort caused by pecuniary incentives or merely thirst for the thrill of victory (TOV)? Prior literature has not separated the different effects. We look at performance in horse and dog racing and fi...
The purposes of this study were to characterize measures of fluid intake and perception of thirst in women over a 6-week period of exercise-heat acclimation and outdoor training and examine if this lengthy acclimation period would result in changes in fluid intake that differ from those previously reported in men utilizing a shorter acclimation protocol of 8-10 days. Voluntary water intake (11-...
Changes in osmolality or extracellular NaCl concentrations are detected by specialized neurons in the hypothalamus to increase vasopressin (VP) and stimulate thirst. Recent in vitro evidence suggests this process is mediated by an NH2-terminal variant of the transient receptor potential vanilloid type 1 (TRPV1) channel expressed by osmosensitive neurons of the lamina terminalis and vasopressine...
BACKGROUND Carbohydrate-rich liquid drinks (CRLDs) have been recommended to attenuate insulin resistance by shortening the preoperative fasting interval. The aim of our study the effect of preoperative oral administration of CRLDs on the well-being and clinical status of patients. METHODS A randomized, double blind, prospective study of patients undergoing open colorectal operations (CR) and ...
We have previously demonstrated that acute third ventricle injections of both lead and cadmium prevent the dipsogenic response elicited by dehydration or by central injections of dipsogenic agents such as angiotensin II, carbachol and isoproterenol in rats. We have also shown that the antidipsogenic action of cadmium may be due, at least in part, to activation of thirst-inhibitory central serot...
What people feel shapes their perceptions of others. In the studies reported here, we examined the assimilative influence of visceral states on social judgment. Replicating prior research, we found that participants who were outside during winter overestimated the extent to which other people were bothered by cold (Study 1), and participants who ate salty snacks without water thought other peop...
The cingulate cortex and insula are among the neural structures whose activations have been modulated in functional imaging studies examining discrete states of thirst and drinking to satiation. Building upon these findings, the present study aimed to identify neural structures that change their pattern of activation elicited by water held in the mouth in relation to the internal body state, i....
To assess the significance of stimulation studies suggesting an anteroventral third ventricle (AV3V) dipsogenic site of action for hyperosmotic and angiotensin thirst stimuli, electrolytic lesions of periventricular tissue surrounding AV3V were produced under ether anesthesia in rats preselected for responsiveness to subcutaneous angiotensin and hypertonic NaCl thirst challenges. Lesions limite...
Dehydration is one of the ten most frequent diagnoses responsible for the hospital admission of elderly in the United States. It is associated with increased mortality, morbidity and an estimated cost of 1.14 billion per year (Xiao et al., 2004; Schlanger et al., 2010; Pretorius et al., 2013; Frangeskou et al., 2015). Older individuals are predisposed to dehydration encephalopathy as a result o...
