OBJECTIVE: The prognosis from acute ischemic stroke (AIS) is worsened by poststroke medical complications. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS are not known. METHODS: We queried the Nationwide Inpatient Sample (2002-2011) to identify all patients with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariable analysis was utilized to identify risk factors for GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes...

BACKGROUND: It is not known whether older patients with acute heart failure (HF) receiving tolvaptan have decreased mortality rates and a better long-term prognosis than patients who receive furosemide. We conducted a systematic review of randomized controlled trials (RCTs) to address this issue. METHODS: The Medline, Embase, and Cochrane Library databases were searched for English-language RCTs published before September 2016 comparing tolvaptan with furosemide treatment in older patients (>65 years old) after acute HF...

Hyponatremia is the most common electrolyte disorder among hospitalized patients and it is sometimes considered as a poor outcome predictor. Its correction is thus indicated, even in asymptomatic patients. The conventional treatment is represented by fluid restriction in presence of euvolemia or hypervolemia; whereas loop diuretics are used in some hypervolemic conditions (cardiac heart failure, liver cirrhosis and nephrotic syndrome) and intravenous isotonic or hypertonic solution are administered in hypovolemic conditions...

Metal oxides are commonly used as electrolytes for redox-based resistive switching memories. In most cases non-noble metals are directly deposited as ohmic electrodes. We demonstrate, that irrespective on bulk thermodynamics predictions, intermediate oxide film of few nm thickness is always formed at the metal/insulator interface and this layer significantly contributes to reliable switching characteristics. We have tested metal electrodes and metal oxides mostly used for memristive devices i.e. (Ta, Hf and Ti) and (Ta2O5, HfO2 and SiO2)...

OBJECTIVE: Visceral artery aneurysms (VAAs) are rare but often repaired because of dire consequences of rupture. This is a population-based evaluation of chronologic trends in management, risk factors, and outcomes of endovascular and open therapy. METHODS: The 2003 to 2013 Agency for Healthcare Research and Quality (AHRQ) National Inpatient Sample (NIS) database was reviewed. Cases with primary diagnosis of VAA and undergoing endovascular or open repair were identified...

Electrolyte and acid-base disturbances are frequent in patients with end-stage liver disease; the underlying physiopathological mechanisms are often complex and represent a diagnostic and therapeutic challenge to the physician. Usually, these disorders do not develop in compensated cirrhotic patients, but with the onset of the classic complications of cirrhosis such as ascites, renal failure, spontaneous bacterial peritonitis and variceal bleeding, multiple electrolyte, and acid-base disturbances emerge. Hyponatremia parallels ascites formation and is a well-known trigger of hepatic encephalopathy; its management in this particular population poses a risky challenge due to the high susceptibility of cirrhotic patients to osmotic demyelination...

Central pontine myelinolysis (CPM) is a demyelinating disorder of central nervous system which involves central portion of the pons and sometimes extrapontine areas also. It is commonly reported in settings of hyponatraemia or its rapid correction, but in the last few years it has also been reported in patients with diabetes in the absence of electrolyte disturbances or correction of serum osmolality. Here we report a case of a 20-year-old female patient, with a known history of type 1 diabetes mellitus, who presented with acute onset spastic quadriparesis with dysarthria and mild ataxia which evolved over 2 weeks...

Layered lithium transition metal oxides (LTMO) are promising candidate cathode materials for next-generation high-energy density lithium ion battery. The challenge for using this category of cathode is the capacity and voltage fading, which is believed to be associated with the layered structure disordering, a process that is initiated from the surface or solid-electrolyte interface and facilitated by transition metal (TM) reduction and oxygen vacancy formation. However, the atomic level dynamic mechanism of such a layered structure disordering is still not fully clear...

BACKGROUND: Primary hyperparathyroidism (PHPT) is a frequently encountered endocrine disorder due to benign neoplastic lesions or gland hyperplasia. It is often discovered incidentally when routine lab work reveals hypercalcemia. METHODS: This case presents a 55-year-old male with a neck mass and electrolyte irregularities consistent with PHPT. However, his laboratory values suddenly normalized prior to surgery. RESULTS: Post-operative pathologic analysis of the specimen demonstrated massive infarction of the affected gland, and explained the spontaneous resolution of the patient's electrolyte derangements...

Mild encephalitis with reversible lesion in the splenium is a clinicoradiological syndrome characterized by a variegated symptomatology with a solitary mass in the central portion of the splenium of the corpus callosum. Complete spontaneous resolution is the hallmark of this syndrome, though its pathogenesis is still unknown. We describe the clinical picture of a 51-year-old woman who developed a partial sensitive seizure, with MRI evidence of a lesion localized in the posterior portion of the corpus callosum...

We report a 16-year-old girl who was diagnosed with acute leukaemia and a marked leucocytosis >200 × 10(9)/L. She presented with marked hypophosphatemia, hypokalemia, acute renal failure and acute respiratory failure. These electrolytes disturbances may indicate rapid tumour genesis. These ominous findings required urgent treatment to halt the crises of rapid leukemic cell proliferation. CONCLUSION: Mark hypophosphatemia and hypokalemia may be presenting electrolyte abnormalities in a patient with acute leukaemia, and these may be indicators of aggressive tumour genesis...

Aldosterone regulates electrolyte and fluid homeostasis through binding to the mineralocorticoid receptors (MRs). Previous work provides evidence for a role of aldosterone in alcohol use disorders (AUDs). We tested the hypothesis that high functional activity of the mineralocorticoid endocrine pathway contributes to vulnerability for AUDs. In Study 1, we investigated the relationship between plasma aldosterone levels, ethanol self-administration and the expression of CYP11B2 and MR (NR3C2) genes in the prefrontal cortex area (PFC) and central nucleus of the amygdala (CeA) in monkeys...

Understanding the short-range molecular motions of organic ionic plastic crystals is critical for the application of these materials as solid-state electrolytes in electrochemical devices such as lithium batteries. However, the theory of short-range-motions was originally developed for simple molecular plastic crystals and does not take account of strong interionic interactions that are present in organic ionic plastic crystals. Here we report a fundamental investigation of the dynamic behavior of an archetypal example triethyl(methyl)phosphonium bis(fluorosulfonyl)amide ([P1222][FSI]) through calorimetry, impedance spectroscopy, synchrotron X-ray diffraction, and solid-state NMR and Raman spectroscopies...

AIMS: Hyponatraemia is an electrolyte disorder that occurs in advanced congestive heart failure (HF) and worsens prognosis. We explored the usefulness of tolvaptan, which has shown promising results in the treatment of this condition. METHODS AND RESULTS: This study is based on a retrospective national registry (2011-15) of patients hospitalized with refractory HF and hyponatraemia who agreed to receive tolvaptan when standard treatment was ineffective. The benefit of tolvaptan was analysed according to the following criteria: normalization ([Na(+)] ≥ 135 mmol/L) or increased sodium levels [Na(+)] ≥ 4 mEq/L on completion of treatment, and increase in urine output by 300 or 500 mL at 48 h...

We introduce a skin-friendly electronic system that enables human-computer interaction (HCI) for swallowing training in dysphagia rehabilitation. For an ergonomic HCI, we utilize a soft, highly compliant ("skin-like") electrode, which addresses critical issues of an existing rigid and planar electrode combined with a problematic conductive electrolyte and adhesive pad. The skin-like electrode offers a highly conformal, user-comfortable interaction with the skin for long-term wearable, high-fidelity recording of swallowing electromyograms on the chin...

The Malpighian tubules of insects are structurally simple but functionally important organs, and their integrity is important for the normal excretory process. They are functional analogs of human kidneys which are important physiological organs as they maintain water and electrolyte balance in the blood and simultaneously help the body to get rid of waste and toxic products after various metabolic activities. In addition, it receives early indications of insults to the body such as immune challenge and other toxic components and is essential for sustaining life...
