pump furosemide

BACKGROUND: Furosemide is an off-label drug, frequently used as a diuretic in neonates with oliguria and/or edema. Its clearance in preterm neonates is lower than in term neonates or children. We aimed, herein, to clarify furosemide clearance (CL) in very preterm (VP) neonates (<28 weeks' gestation) within the first 2 weeks of life and identify the factors predictive of the pharmacokinetics (PK) parameters, such as CL. METHODS: Furosemide was administered at 0...

Treatment with neurotrophins prevents degeneration of spiral ganglion cells (SGCs) after severe hair cell loss. In a previous study we demonstrated a long-lasting effect with brain-derived neurotrophic factor (BDNF) after cessation of treatment. In that study the survival of the SGC cell bodies was examined. Here we address the question whether their peripheral processes and central processes (axons) were protected by this treatment as well in the cochleas of the aforementioned study. Guinea pigs were deafened by co-administration of kanamycin and furosemide...

Similar to other organs, renal lymphatics remove excess fluid, solutes, and macromolecules from the renal interstitium. Given the kidney's unique role in maintaining body fluid homeostasis, renal lymphatics may be critical in this process. However, little is known regarding the pathways involved in renal lymphatic vessel function, and there are no studies on the effects of drugs targeting impaired interstitial clearance, such as diuretics. Using pressure myography, we showed that renal lymphatic collecting vessels are sensitive to changes in transmural pressure and have an optimal range of effective pumping...

Primary amoebic encephalitis (PAM) is a lethal disease caused by the opportunistic pathogen, Naegleria fowleri. This amoebic species is able to live freely in warm aquatic habitats and to infect children and young adults when they perform risk activities in these water bodies such as swimming or splashing. Besides the need to increase awareness of PAM which will allow an early diagnosis, the development of fully effective therapeutic agents is needed. Current treatment options are amphotericin B and miltefosine which are not fully effective and also present toxicity issues...

Besides the respiratory system, severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection was shown to affect other essential organs such as the kidneys. Early kidney involvement during the course of infection was associated with worse outcomes, which could be attributed to the direct SARS-CoV-2 infection of kidney cells. In this study, the effect of commonly used medications on the expression of SARS-CoV-2 receptor, angiotensin-converting enzyme (ACE)2, and TMPRSS2 protein in kidney tissues was evaluated...

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) may be used to treat peritoneal based malignancies, such as epithelial ovarian cancer (EOC). Despite results of clinical trials supporting an increasing indication for HIPEC in EOC, concerns have existed regarding morbidity and challenges with initiating HIPEC at an institutional level. The objective of this review is to describe evidence-based recommendations to guide implementation of a HIPEC program, following our experience at a high-volume tertiary care center...

In recent years, home medical care has been strongly promoted. As a consequence, the conditions managed in home medical care have become increasingly diverse. Heart failure is one of the most common disorders after malignant diseases. Patients with chronic heart failure (CHF) are often forced into hospitalization because of the inability to control symptoms with oral medications, even though they hope to stay at home. Recently, we have experienced a case where the patient required continuous administration of dobutamine at home...

BACKGROUND: Hypokalemia is a well-described electrolyte disturbance in patients on peritoneal dialysis (PD). Hyperkalemia, however, is still overlooked, although it also represents a risk factor for mortality. Angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers (ACE/ARB), diuretics, and proton pump inhibitor (PPI) can interfere with potassium levels in these patients. METHODS: This is a retrospective study that evaluated monthly serum potassium in a 5-year period...

The aim of the present study was to elucidate trends in managing acute heart failure (AHF) patients who require intensive care over a 19-year period. We evaluated a total of 1,475 AHF patients, comparing patient backgrounds, in-hospital management, and prognosis according to the year of admission (2000s group, n = 608 and 2010s group, n = 867). A multivariate logistic regression analysis revealed that age (≥75 years; odds ratio [OR] 1.334, 95% confidence interval [CI] 1.048 to 1.700), systolic blood pressure (<100 mm Hg; OR 1...

BACKGROUND: Clinical guidance is needed to initiate, continue, and discontinue drug treatments near the end of life. AIM: To identify drugs and drug classes most often adequate, questionable, or inadequate for older people at the end of life. DESIGN: Delphi consensus survey. SETTING/PARTICIPANTS: Forty European experts in geriatrics, clinical pharmacology, and palliative medicine from 10 different countries. Panelists were asked to characterize drug classes as "often adequate," "questionable," or "often inadequate" for use in older adults aged 75 years or older with an estimated life expectancy of ≤ 3 months...

A 43-year-old man was referred to our hospital in June 2014 because of severe heart failure. He was diagnosed with familial dilated cardiomyopathy and was administered oral tolvaptan and amiodarone for atrial and ventricular tachycardia. Since up-titration of carvedilol had failed and he was dependent on dobutamine, a left ventricular assist device (LVAD) was implanted. Tolvaptan and furosemide were both discontinued after LVAD implantation and he was discharged from the hospital. Thirteen months later, he was hospitalized for lethargy and hyponatremia of 108 mEq/L, with an antidiuretic hormone level of 2...

OBJECTIVES: As proof of concept, this prospective, observational study assessed the feasibility and early clinical outcomes of performing on-pump cardiac surgery with the RenalGuard system. BACKGROUND: Acute kidney injury (AKI) is reported in up to 30% of patients undergoing cardiac surgery and is a recognised independent predictor of both morbidity and mortality. Forced diuresis with the RenalGuard system reduces the incidence of AKI during percutaneous coronary intervention procedures but its use in cardiac surgery has not been explored...

BACKGROUND AND OBJECTIVES: Several drugs used in CKD can prolong electrocardiographic conduction. We examined the use of electrocardiogram QT-prolonging medications in predialysis CKD and their association with QT duration. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In total, 3252 Chronic Renal Insufficiency Cohort participants with at least one study electrocardiogram between 2003 and 2011 were included. QT-prolonging medications used in 100 or more visits ( n =16,451 visits) along with diuretics and proton pump inhibitors, given their potential for electrolyte disturbances, were examined for QT interval prolongation...

The activation of renin-angiotensin-aldosterone-vasopressin system is a key factor in the formation of ascites due to splanchnic vasodilation in cirrhosis. In theory, aldosterone antagonists, contraction of blood vessels, vasopressin V2 receptor, and angiotensin receptor antagonists are important targets for the prevention and treatment of cirrhotic ascites. The 15%-20% of patients with cirrhotic ascites that show no response to at least one week's treatment with potent diuretics (spironolactone 160 mg/d combined with furosemide 80 mg/d) are considered to have refractory ascites...

INTRODUCTION: Acute renal dysfunction is a common complication of cardiac surgery. Furosemide is used in prevention, or treatment, of acute renal dysfunction. This study was conducted to evaluate the protective effects of intra- and early postoperative furosemide infusion on preventing acute renal dysfunction in elective adult cardiac surgery. METHODS: Eighty-one patients, candidates of elective cardiac surgery, were enrolled in this study in either the furosemide (n=41) or placebo (n=40) group...

Inorganic phosphate (Pi) is an essential nutrient for all organisms because it is required for a variety of biochemical processes, such as signal transduction and the synthesis of phosphate-containing biomolecules. Assays of (32)Pi uptake performed in the absence or in the presence of Na(+) indicated the existence of a Na(+)-dependent and a Na(+)-independent Pi transporter in Phytomonas serpens. Phylogenetic analysis of two hypothetical protein sequences of Phytomonas (EM1) showed similarities to the high-affinity Pi transporters of Saccharomyces cerevisiae: Pho84, a Na(+)-independent Pi transporter, and Pho89, a Na(+)-dependent Pi transporter...

BACKGROUND: Elevated intracranial pressure is one of the most common problems in patients with diverse intracranial disorders, leading to increased morbidity and mortality. Effective management for increased intracranial pressure is based mainly on surgical and medical techniques with hyperosmolar therapy as one of the core medical treatments. The study aimed to explore the effects of continuous micro-pump infusions of 3% hypertonic saline combined with furosemide on intracranial pressure control...

Patients with advanced cirrhosis have abnormal sodium homoeostasis. The study was undertaken to quantify the sodium transport across the plasma membrane of red blood cells (RBC) in patients with cirrhosis. RBC efflux and influx of sodium were studied in vitro with tracer (22) Na(+) according to linear kinetics in 24 patients with cirrhosis and 14 healthy controls. The sodium efflux was modified by ouabain (O), furosemide (F) and a combination of O and F (O + F). RBC sodium was significantly decreased (4·6 versus control 6·3 mmol l(-1) , P<0·001) and directly related to serum sodium (r = 0·57, P<0·05)...

A 35-year-old Japanese woman was admitted with coma following flu-like symptoms. She was diagnosed with diabetic ketoacidosis and fulminant type 1 diabetes (FT1D) and received intravenous infusion of insulin and saline. The next day, the ketoacidosis disappeared, and she recovered consciousness. However, extensive ST-segment elevations in the electrocardiogram appeared with a positive troponin test, and the patient developed pulmonary edema on day 3. An echocardiogram showed globally reduced wall motion of the left ventricle and mild pericardial effusion...

We expanded a mathematical model of transepithelial transport along the rat nephron to include the transport of Ca(2+) and probe the impact of calcium-sensing mechanisms on Ca(2+) reabsorption. The model nephron extends from the medullary thick ascending limb (mTAL) to the inner medullary collecting duct (IMCD). Our model reproduces several experimental findings, such as measurements of luminal Ca(2+) concentrations in cortical tubules, and the effects of furosemide or deletion of the transient receptor potential channel vanilloid subtype 5 (TRPV5) on urinary Ca(2+) excretion...
