REVIEW
Fintan Hughes, Monty Mythen, Hugh Montgomery
Background: Dehydration is highly prevalent and is associated with adverse cardiovascular and renal events. Clinical assessment of dehydration lacks sensitivity. Perhaps a patient's thirst can provide an accurate guide to fluid therapy. This systematic review examines the sensitivity of thirst in responding to changes in plasma osmolality in participants of any age with no condition directly effecting their sense of thirst. Methods: Medline and EMBASE were searched up to June 2017...

Thirst aroused in the forebrain by angiotensin II (AngII) or buccal drying motivates terrestrial vertebrates to search for water, whereas aquatic fish can drink surrounding water only by reflex swallowing generated in the hindbrain. Indeed, AngII induces drinking through the hindbrain even after removal of the whole forebrain in aquatic fish. Here we show that AngII induces thirst also in the amphibious mudskipper goby without direct action on the forebrain, but through buccal drying. Intracerebroventricular injection of AngII motivated mudskippers to move into water and drink as with tetrapods...

Nocardiosis is a rare infectious disease entity that mostly affects the lungs, brain, or skin of immunocompromised individuals. Recent reports of pulmonary nocardiosis (PN) in patients with chronic obstructive pulmonary disease (COPD) as the only risk factor suggest a possible association between nocardiosis and COPD. Herein, we present a case of ventilator-dependent PN in a patient with a moderate degree of COPD. A high level of suspicion for PN should be maintained when encountered with COPD patients complaining of symptoms of pneumonia and excessive thirst...

In humans, activity in the anterior midcingulate cortex (aMCC) is associated with both subjective thirst and swallowing. This region is therefore likely to play a prominent role in the regulation of drinking in response to dehydration. Using functional MRI, we investigated this possibility during a period of "drinking behavior" represented by a conjunction of preswallow and swallowing events. These events were examined in the context of a thirsty condition and an "oversated" condition, the latter induced by compliant ingestion of excess fluid...

BACKGROUND: Intravenous (IV) fluid therapy should be individualized according to each patient's weight, disease, and comorbidities, as well as the type and duration of the operative procedure. Laparoscopic cholecystectomy represents one of the most common, short-duration operations; thus, the aim of this study was to assess the necessity of postoperative administration of IV fluids. METHOD: A randomized clinical trial with patients undergoing elective laparoscopic cholecystectomy was performed...

Berries contain bioactive compounds that may affect children's cognitive function positively, while hunger and thirst during lessons before lunch affect academic performance negatively. This pilot study addresses methodological challenges in studying if a berry smoothie, offered to schoolchildren as a mid-morning beverage, affects academic performance. The objective was to investigate if a cross-over design can be used to study these effects in a school setting. Therefore, in order to investigate assay sensitivity, 236 Swedish children aged 10-12 years were administered either a berry smoothie (active) or a fruit-based control beverage after their mid-morning break...

Meriones shawi (M. shawi) is a particular semi-desert rodent known by its resistance to long periods of thirst. The aim of the present investigation is to clarify the underlying mechanisms allowing M. shawi to resist to hard conditions of dehydration. For this reason we used two different approaches: i) a morphometric study, which consists in measuring the effect of dehydration on body and kidneys weights as well as the report kidney weight/body weight, ii) By immunohistochemistry, we proceed to study the effect of dehydration on the immunoreactivity of central vasopressin (AVP) and the kidney aquaporin-2 (AQP-2) which is a channel protein that allows water to permeate across cell membranes...

Background: Primary care clinicians will see a higher incidence of type 2 diabetes in adult patients, and the diagnosis and management of an initial presentation of type 1 diabetes can pose challenges to clinicians who see it less frequently. Symptoms of hyperglycemia and risk of ketoacidosis may be missed. Further, endocrine autoimmune disease can run together in patients and families. Case presentation: A 49-year-old Caucasian female with history of pituitary adenoma and Graves' disease with history of thyroid ablation presented in the outpatient setting due to hand tingling of her right middle finger that was worse in the mornings and improved throughout the day...

Flammer syndrome (FS) is a term to blanket a cluster of vascular and nonvascular signs and symptoms linked to primary vascular dysregulation (PVD), increased sensitivity to various stimuli (stress, drugs, etc.) and altered sense regulation such as pain, smell and thirst perception. On one hand, disruption of blood barrier and homeostasis of the body are the main targets of vascular irregularity. Inflammation and immune disorders including autoimmunity are considered as a consequence of the abnormal vascular regulation processes...

A 59-year-old man had been admitted to another hospital because of diplopia and thirst at the beginning of March and was diagnosed with diabetic ketoacidosis. He was referred to our hospital because he had limb weakness, dysarthria, and bilateral sensory impairment of the upper limbs, which worsened rapidly from the middle of March, although plasma glucose had been well controlled after the initiation of insulin therapy in the previous hospital. Contrast spinal MRI in our hospital revealed hyperintense lesions at the level of C4 to C5 and T10...

Most investigators use a single treatment such as water deprivation or dietary sodium deficiency to evaluate thirst or sodium appetite, which underlie behavioral responses to body fluid challenges. The goal of the present experiments was to assess the effects of combined treatments in driving behaviors. Therefore, we evaluated the effect of combined overnight water deprivation and dietary sodium deficiency on water intake and salt intake by adult male rats in 2-bottle (0.5M NaCl and water) tests. Overnight water deprivation alone increased water intake, and 10days of dietary sodium deficiency increased 0...

Older adults' definitions of digital technology, and experiences of digital inclusion sessions, were examined using qualitative approaches. Seventeen older adults (aged between 54 and 85 years) participated in two focus groups that each lasted approximately 90 min to explore how older adults understood technology within their lived experience. Interpretative phenomenological analysis yielded two main themes: thirst for knowledge and a wish list for digital technology sessions. A separate content analysis was performed to identify what technology older adults identified as digital technology...
