Sacubitril/valsartan (LCZ696) is indicated for the treatment of heart failure with reduced ejection fraction. Absorption of sacubitril/valsartan and conversion of sacubitril (prodrug) to sacubitrilat (neprilysin inhibitor) was rapid with maximum plasma concentrations of sacubitril, sacubitrilat, and valsartan (angiotensin receptor blocker) reaching within 0.5, 1.5-2.0, and 2.0-3.0 h, respectively. With a twofold increase in dose, an increase in the area under the plasma concentration-time curve was proportional for sacubitril, ~1...

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...

BACKGROUND: This was a retrospective study to determine whether lack of furosemide responsiveness (LFR) predicts acute kidney injury (AKI) after cardiopulmonary bypass surgery in infants. METHODS: Infants (less than 1 year of age) undergoing cardiopulmonary bypass surgery, receiving routine postoperative furosemide (0.8 to 1.2 mg/kg per dose between 8 and 24 hours after surgery) were included. Urine output was measured 2 and 6 hours after furosemide dose. Lack of furosemide responsiveness was defined a priori as urine output less than 1 mL · kg(-1) · h(-1) after furosemide...

RATIONALE AND OBJECTIVES: Quantitative measurement of renal perfusion in murine models provides important information on the organ physiology and disease states. The 1-T desktop magnetic resonance imaging has a small footprint and a self-contained fringe field. This resultant flexibility in siting makes the system ideal for preclinical imaging research. Our objective was to evaluate the capability of the 1-T desktop magnetic resonance imaging to measure mouse renal perfusion without the administration of exogenous contrast agents...

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...

CASE SERIES SUMMARY: Two cats were evaluated for progressive exercise intolerance, dyspnea and unilateral infiltrate of the left lung. Computed tomography angiography (CTA) revealed absence of the right pulmonary artery in both cats with systemic arterial collateral vessels perfusing the right segmental pulmonary arteries. In one case, the collateral vessels arose from the esophageal artery, while in the other case they derived off the right costocervical trunk. One cat was diagnosed with pulmonary hypertension and was euthanized owing to progressive respiratory distress despite medical management with sildenafil, pimobendan, clopidogrel and furosemide...

OBJECTIVE: Heart failure is a major cause of disease burden in sub-Saharan Africa (SSA). There is an urgent need for better strategies for heart failure management in this region. However, there is little information on the capacity to diagnose and treat heart failure in SSA. We aim to provide a better understanding of the capacity to diagnose and treat heart failure in Kenya and Uganda to inform policy planning and interventions. METHODS: We analysed data from a nationally representative survey of health facilities in Kenya and Uganda (197 health facilities in Uganda and 143 in Kenya)...

Uropathogenic Escherichia coli often produce the virulence factor α-hemolysin (HlyA), and the more severe the infection, the likelier it is to isolate HlyA-producing E. coli from patients. HlyA forms pores upon receptor-independent insertion of the toxin into biological membranes and it has been substantiated that HlyA-induced hemolysis is amplified by toxin-induced ATP release and activation of P2X receptors. Thus, hemolysis inflicted by HlyA is a protracted process involving signal transduction. It consists of early, marked cell shrinkage followed by swelling and eventually lysis...

The aim of this study was to formulate and evaluate chitosan (CS)/alginate (ALG) nanoparticles (NPs) loaded with furosemide (FSM) in an attempt to enhance its release, permeability and bioavailability. Non-everted gut sac method was used to evaluate the ex vivo permeation of FSM from its suspension and the selected CS/ALG NPs formulation. The pharmacokinetic parameters of FSM subsequent to oral administration of the selected formulation were assessed in rats. In vivo subacute toxicity study of the prepared blank and FSM loaded formulations was evaluated in rats...

BACKGROUND: We hypothesize that autoantibodies are induced after the blood-brain barrier is damaged by stroke and the risk of bullous pemphigoid (BP) is increased after stroke. We assess the risk of BP after first-ever stroke in a nationwide population-based cohort of first-ever stroke patients. METHODS: We extracted data from the Longitudinal Health Insurance Database 2005 and identified patients with first-ever stroke as well as control patients matched for age, gender, and year of enrollment...

OBJECTIVE/BACKGROUND: Hepatic veno-occlusive disease (VOD) is well recognized potentially serious regimen-related toxicity seen after stem cell transplantation. Severe VOD is associated with poor long-term outcomes with very high mortality. Besides supportive care, only defibrotide has been found to be effective in the management of VOD. The recommended dose of defibrotide is 25mg/kg/d but there has been no classical dose finding study done for this drug. A higher dose of defibrotide is associated with increased risk of bleeding and this drug is prohibitively expensive...

The importance of multidrug resistance-associated protein 4 (Mrp4/Abcc4) in limiting the penetration of Mrp4 substrate compounds into the central nervous system across the blood-brain barrier (BBB) was investigated using Mrp4(-/-) mice. Significant ATP-dependent uptake by MRP4 was observed for ochratoxin A, pitavastatin, raltitrexed (Km 43.7 μM), pravastatin, cGMP, 2,4-dichlorophenoxyacetate, and urate. The defect in the Mrp4 gene did not affect the brain-to-plasma ratio (Kp,brain) of quinidine and dantrolene...

AIM: This review assessed the evidence on risk factors for the occurrence of adverse health outcomes after discharge (i.e. unplanned readmission or adverse drug event after discharge) that are potentially modifiable by clinical pharmacist interventions. The findings were compared with patient characteristics reported in guidelines that supposedly indicate a high risk of drug-related problems. METHODS: First, guidelines and risk assessment tools were searched for patient characteristics indicating a high risk of drug-related problems...

AIMS: The main terminology used to describe heart failure (HF) is based on measurement of the left ventricular ejection fraction (LVEF). LVEF in the range of 40-49% was recently defined as HF with mid-range EF (HFmrEF) by the 2016 European Society of Cardiology guidelines. The purpose of our study was to assess the clinical profile and prognosis of patients with HF according to this new classification. METHODS AND RESULTS: A total of 482 patients referred for HF were retrospectively included over a period of 1 year...

We aimed to (1) investigate the relation between diuretic response (DR) with or without systemic congestion and prognosis and (2) explore the potential predictors of poor DR for risk stratification in patients with acute decompensated heart failure (ADHF). We enrolled 186 consecutive patients hospitalized for ADHF. The DR was defined as (body weight at discharge - body weight at admission)/40 mg furosemide or equivalent loop diuretic dose. Systemic congestion on admission was simply evaluated by the presence of leg edema or jugular venous distention...

OBJECTIVES: Hip arthroscopy utilization has significantly increased in recent years. While it is a relatively safe procedure, it is not without risk. Life-threatening complications, albeit rare, can potentially occur and must be appropriately recognized and treated. We describe 2 cases in which patients' undergoing hip arthroscopy developed pulmonary edema and their respective courses of treatment. METHODS: Both patients were being treated for symptomatic femoroacetabular impingement (FAI), with labral tears, requiring operative management after a failed trial of conservative management...

Muscle wasting or sarcopenia contributes to morbidity and mortality in patients with cancer, renal failure, or heart failure, and in elderly individuals. Na(+)-K(+)-2Cl(-) cotransporter 1 (NKCC1) is highly expressed in mammalian skeletal muscle, where it contributes to the generation of membrane ion currents and potential. However, the physiologic function of NKCC1 in myogenesis is unclear. We investigated this issue using the NKCC1 inhibitors bumetanide and furosemide, which are commonly used loop diuretics...
