BACKGROUND: Iodine is essential for thyroid hormone synthesis, and iodine deficiency may result in thyroid disorders including goiter and hypothyroidism. Patients on long-term enteral nutrition (EN) or parenteral nutrition (PN) may be at risk for micronutrient deficiencies. The recommended daily allowance for iodine intake is 150 μg for nonpregnant adults. However, there is no current consensus among scientific societies regarding the quantity of iodine to be added in adult EN and PN formulations...

PURPOSE OF REVIEW: To evaluate the existing evidence on the passive leg raising (PLR) test for fluid responsiveness prediction. RECENT FINDINGS: It has been well established that either insufficient or excessive fluid administration derives in worse outcomes in critically ill patients, highlighting that a more accurate assessment of fluid management is required. Accordingly, several cardiovascular indices have been tested to improve our ability to predict patients' response to fluid loading at the bedside, the so-called functional hemodynamic monitoring...

People living in tropical climates spend much of their time in confined air-conditioned spaces, performing normal daily activities. This study investigated the effect of distilled water (W) or isotonic beverage (IB) on the hydration status in subjects living under these conditions. In a randomized crossover design, forty-nine healthy male subjects either consumed beverage or IB over a period of 8 h (8 h) in a controlled air-conditioned environment. Blood, urine, and saliva samples were collected at baseline and after 8 h...

REVIEW
Dana C Miskulin, Daniel E Weiner
Despite having thousands of blood pressure (BP) readings on individual dialysis patients over the course of a year, our knowledge about the optimal assessment of BP, the mechanisms underlying hypertension and its management remain incomplete. Observational studies reveal that BP is lower at home than when measured in the dialysis unit. However, we do not know if using home vs. in-center measurements to guide treatment decisions improves BP control and/or clinical outcomes. Moreover, a recent US study suggests that typical hemodialysis patients are unlikely to adhere to home monitoring over the long term...

The aim of this study was to estimate uric acid renal stone prevalence rates of adults in different countries of the world. PubMed was searched for papers dealing with "urinary calculi and prevalence or composition" for the period from January 1996 to June 2016. Alternative searches were made to collect further information on specific topics. The prevalence rate of uric acid stones was computed by the general renal stone prevalence rate and the frequency of uric acid stones in each country. After the initial search, 2180 papers were extracted...

Swallowing dysfunction is related to long-term weight loss and reduced body mass index in patients with head and neck cancer. We describe a 76-y-old woman who had severe sarcopenic dysphagia and atrophy of the reconstructed tongue for 17 mo after subtotal glossectomy due to tongue cancer and lost 14 kg during that period. Upon admission, the patient received diagnoses of malnutrition in the context of social or environmental circumstances with insufficient energy intake, loss of muscle mass, localized fluid accumulation, weight loss, and sarcopenia due to reduced skeletal muscle mass (skeletal muscle index <3...

Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, (123)I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging...

Julie B Lindower
Fetal water balance is dependent prenatally on the placental transfer of water from maternal to fetal circulation. Adequate amniotic fluid volume is one indicator of stable fetal status and development. Excessive or less than expected amniotic fluid volume may be a precursor to postnatal morbidity and mortality. Postnatal transition is marked by predictable changes in body water including contraction of extracellular volume and insensible fluid loss, primarily across the skin barrier. The degree to which these occur is determined by gestational and postnatal age...

BACKGROUND: In Western Australia (WA), most stable patients undergoing haemodialysis receive treatment in a satellite setting where no doctors are on-site during treatment hours, so nurses must make critical decisions about fluid removal. Some patients regularly experience adverse events during dialysis (intradialytic), often due to excessive ultrafiltration goals, with intradialytic hypotension being particularly challenging. Ultrasound of the inferior vena cava has been previously demonstrated being a rapid and non-invasive method for volume assessment on haemodialysis patients, thus could hold valuable information for the treating nurse...

The CK/PCr-system, with creatine (Cr) as an energy precursor, plays a crucial role in cellular physiology. In the kidney, as in other organs and cells with high and fluctuating energy requirements, energy-charged phospho-creatine (PCr) acts as an immediate high-energy source and energy buffer, and as an intracellular energy transport vehicle. A maximally filled total Cr (Cr plus PCr) pool is a prerequisite for optimal functioning of the body and its organs, and health. Skeletal- and cardiac muscles of dialysis patients with chronic kidney disease (CKD) are depleted of Cr in parallel with the duration of dialysis...

There is a growing interest in the effects of plasma sodium levels on postoperative outcomes. A trend of using balanced crystalloid solutions is based on the extensive data on chloride and the strong ion difference-related acidosis. However, effects of sodium are often overlooked in this context. The aim of the study was to establish the effects of the routine use of Lactated Ringer’s Solution (RL) on postoperative changes in sodium concentrations and whether these changes result in metabolic acidosis. We performed database analysis of 358 consecutive elective on-pump cardiac surgery cases in a tertiary referral university hospital...

Data collected in vivo is essential for advising decisions on drug screening and development and basic research, and animal models are used extensively for acquiring experimental measurements. Traditionally, collection of specimens has been invasive, stressful to animal subjects, labor intensive, time-consuming and costly, and required many animals when using small models with low fluid volumes, such as rats or mice. Utilizing automated microsampling (AMS) alone or in an integrative pharmacology approach to evaluate multiple physiological, pharmacokinetic, and pharmacodynamic endpoints simultaneously in the same animal accomplishes multiple experimental goals...

Volume overload is a hidden, pervasive complication in dialysis patients with dyspnea and pulmonary edema being its main clinical manifestations. Measuring lung water has clinical potential because it allows timely treatment of lung congestion at a preclinical stage. Chest ultrasound (US) is a novel, well-validated technique that allows reliable estimates of lung water in clinical practice. The application of this technique in dialysis patients has shown that an unsuspectedly high proportion of these patients have moderate to severe lung congestion which is usually asymptomatic...

KEY POINTS: The ductal system of the pancreas secretes large volumes of alkaline fluid containing HCO3(-) concentrations as high as 140 mm during hormonal stimulation. A computational model has been constructed to explore the underlying ion transport mechanisms. Parameters were estimated by fitting the model to experimental data from guinea-pig pancreatic ducts. The model was readily able to secrete 140 mm HCO3(-) . Its capacity to do so was not dependent upon special properties of the cystic fibrosis transmembrane conductance regulator (CFTR) anion channels and solute carrier family 26 member A6 (SLC26A6) anion exchangers...

BACKGROUND: Continuous intradialytic calf bioimpedance spectroscopy (cBIS) allows assessment of changes in calf extracellular fluid volume (ECV) to determine dry weight (DW) in hemodialysis patients. During dialysis, calf ECV decreases until excessive ECV has been removed and normalized resistivity ρN,5 rises to values comparable to those of a normal population (cBIS-DW). It is not clear whether chronic kidney disease (CKD) itself influences ρN,5 and whether normal values depend on race and ethnicity...

The main objective of fluid therapy is to increase cardiac output (CO). Large, rapidly administered volumes of fluids are the cornerstone of treating patients in shock to restore circulating volume and improve tissue perfusion. However, determining exactly how much fluid a given patient requires can be challenging. If enough fluid is not given, poor tissue perfusion can lead to ischemia, anaerobic metabolism, and ultimately cell and patient death. Conversely, increased morbidity and mortality associated with excessive intravenous fluid administration has been reported in the human literature in a wide variety of conditions...
