Vesela Georgieva, Yulia Dimitrova
BACKGROUND: Due to the widespread use of bottled water, it is important from a hygienic point of view to ensure that these products have good quality and meet the requirements set out in regulations. METHODS: In the period 2000-2013, a large-scale study (2,500 samples) was carried out on the quality of Bulgarian bottled water as per the microbiological parameters laid down in the European and Bulgarian legislation. Standard microbiological methods were applied. RESULTS: There is strong evidence that the most frequently isolated contaminant in these products was Pseudomonas aeruginosa...

INTRODUCTION: Adipsic diabetes insipidus (ADI) is a very rare disorder, characterized by hypotonic polyuria due to arginine vasopressin (AVP) deficiency and failure to generate the sensation of thirst in response to hypernatraemia. As the sensation of thirst is the key homeostatic mechanism that prevents hypernatraemic dehydration in patients with untreated diabetes insipidus (DI), adipsia leads to failure to respond to aquaresis with appropriate fluid intake. This predisposes to the development of significant hypernatraemia, which is the typical biochemical manifestation of adipsic DI...

BACKGROUND: Smokers with mental illness and their health care providers are often concerned that smoking cessation will worsen mental health. Smokers with mental illness tend to be more nicotine dependent and experience more severe symptoms of nicotine withdrawal, some of which are difficult to distinguish from psychiatric symptoms. In addition, smoking cessation can increase the blood levels and hence side-effects of some psychotropic medications. Improved monitoring of nicotine withdrawal and medication side-effects may help distinguish temporary withdrawal symptoms from psychiatric symptoms and facilitate targeted treatment to help smokers with mental illness manage the acute phase of nicotine withdrawal...

Oligo-anuric individuals receiving hemodialysis (HD) are dependent on the dialysis machine to regulate sodium and water balance. Interest in adjusting the dialysate sodium concentration to promote tolerance of the HD procedure dates back to the early years of dialysis therapy. Evolution of dialysis equipment technologies and clinical characteristics of the dialysis population have prompted clinicians to increase the dialysate sodium concentration over time. Higher dialysate sodium concentrations generally promote hemodynamic stabilization and reduce intradialytic symptoms but often do so at the expense of stimulating thirst and promoting volume expansion...

This study examined the physiological effects of crushed ice ingestion prior to steady state exercise in the heat. Ten healthy males with age (23±3 y), height (176.9±8.7 cm), body-mass (73.5±8.0 kg), V̇O2peak (48.5±3.6 mL·kg·min(-1)) participated in the study. Participants completed 60 min of cycling at 55% of their V̇O2peak preceded by 30 min of pre-cooling whereby 7 g·kg(-1) of thermoneutral water (CON) or crushed ice (ICE) was ingested. The reduction in Tc at the conclusion of pre-cooling was greater in ICE (-0...

Central diabetes insipidus (CDI), characterized by polyuria and polydipsia, is caused by deficiency of arginine vasopressin (AVP), an antidiuretic hormone which acts on V2 receptors in kidney to promote reabsorption of free water. CDI is classified into three subtypes; idiopathic, secondary and familial. A previous study suggests that infundibulo-neurohypophysitis might be an underlying cause of idiopathic CDI. Among secondary CDI, the tumors in the central nervous system such as craniopharyngioma and germ cell tumors are the most frequent causes...

Our bodies are mostly water, and this water is constantly being lost through evaporative and other means. Thus the evolution of robust mechanisms for finding and consuming water has been critical for the survival of most animals. In this Primer, we discuss how the brain monitors the water content of the body and then transforms that physical information into the motivation to drink.

Body fluid conditions are continuously monitored in the brain to regulate thirst and salt-appetite sensations. Angiotensin II drives both thirst and salt appetite; however, the neural mechanisms underlying selective water- and/or salt-intake behaviors remain unknown. Using optogenetics, we show that thirst and salt appetite are driven by distinct groups of angiotensin II receptor type 1a-positive excitatory neurons in the subfornical organ. Neurons projecting to the organum vasculosum lamina terminalis control water intake, while those projecting to the ventral part of the bed nucleus of the stria terminalis control salt intake...

The Flammer syndrome (FS) describes the phenotype of people with a predisposition for an altered reaction of the blood vessels to stimuli like coldness, emotional stress or high altitude. Frequent symptoms are: cold hands and/or feet, low blood pressure, prolonged sleep onset time, reduced feeling of thirst, increased sensitivity to odour, pain, vibration and certain drugs. SF subjects are often ambitious and successful but also perfectionistic and sometimes brooding. Frequent signs are: altered gene expression, prolonged blood flow cessation in nailfold capillaroscopy after cold provocation, reduced autoregulation of ocular blood flow, and reduced vasodilation after stimulation with flickering light...

We explored children's and adults' ability to disengage from current physiological states when forecasting future desires. In Study 1, 8- to 13-year-olds and adults (N = 104) ate pretzels (to induce thirst) and then predicted and explained what they would want tomorrow, pretzels or water. Demonstrating life-span continuity, approximately 70% of participants, regardless of age, chose water and referenced current thirst as their rationale. Individual differences in working memory and undergraduate grade point average were positively related to performance on the pretzel task...

Adipsic diabetes insipidus (ADI) is an extremely rare complication following microsurgical clipping of anterior communicating artery aneurysm (ACoA) and left middle cerebral artery (MCA) aneurysm. It poses a significant challenge to manage due to an absent thirst response and the co-existence of cognitive impairment in our patient. Recovery from adipsic DI has hitherto been reported only once. A 52-year-old man with previous history of clipping of left posterior communicating artery aneurysm 20 years prior underwent microsurgical clipping of ACoA and left MCA aneurysms without any intraoperative complications...

AIM: Loop diuretics and spironolactone are used in patients with hepatic edema, but they are sometimes associated with insufficient responses as well as adverse events. Tolvaptan, a vasopressin type 2 receptor antagonist, was approved for hepatic edema in 2013. A large scale post-marketing surveillance study has been performed to evaluate the effectiveness and safety of tolvaptan in real-world clinical settings. METHODS: Hepatic cirrhosis with insufficient response to conventional diuretics was enrolled...

BACKGROUND: Understanding the patient perspective on healthcare is central to the evaluation of quality. This study measured selected patient-reported outcomes after anaesthesia in order to identify targets for research and quality improvement. METHODS: This cross-sectional observational study in UK National Health Service hospitals, recruited adults undergoing non-obstetric surgery requiring anaesthesia care over a 48 h period. Within 24 h of surgery, patients completed the Bauer questionnaire (measuring postoperative discomfort and satisfaction with anaesthesia care), and a modified Brice questionnaire to elicit symptoms suggestive of accidental awareness during general anaesthesia (AAGA)...

We propose that decisions related to resource management (e.g., intertemporal choice between a smaller-and-sooner reward and a larger-and-later reward) are sensitive to and regulated by fluctuating blood glucose levels. Circulating glucose affects intertemporal choice by means of signaling body energy condition instead of serving as a replenishing resource for effortful cognitive processing. We intend to dissociate calorie-supplying functions from glucose-unique anticipatory effects on behavioral resource management, measured by delay discounting in making intertemporal choices...

ETHNOPHARMACOLOGICAL RELEVANCE: Mesembrine alkaloids are considered to be the primary active constituents of the South African medicinal plant Sceletium tortuosum (L.) N.E.Br. (Aizoaceae), and it is used as the dried or fermented aerial material from the plant, which is known as kanna (aka, channa, kougoed). Traditional regional use ranged from relieving thirst, mild analgesia, and alteration of mood. Current interest has focused primarily on the antidepressant action of preparations based on the plant and commercialization is expanding the recognition and availability of these preparations...

BACKGROUND: The contemporary rise in the number of elective procedures performed in same-day surgery (SDS) requires that health care professionals increase their knowledge of patient satisfaction and recovery, including patient-assessed quality of life. This study investigates the quality of recovery (QoR) of anesthetized SDS patients. METHODS: Data from SDS patients were collected from hospital records at T1 (the morning before operation), T2 (day 1 postsurgery), and T3 (day 4 postsurgery)...

Sodium-depleted animals develop an appetite for aversive concentrations of sodium. Here we show that chemogenetic activation of aldosterone-sensitive neurons that express 11β-hydroxysteroid dehydrogenase type 2 (HSD2) in the nucleus of the solitary tract is sufficient to drive consumption of sodium-containing solutions in mice, independently of thirst or hunger. These HSD2-positive neurons are necessary for full expression of sodium appetite and have distinct downstream targets that are activated during sodium depletion...
