BACKGROUND: Acute kidney injury (AKI) is a common and severe complication of cardiac surgery. There is no effective prevention or treatment. Sildenafil citrate (Revatio®, Pfizer Inc), a phosphodiesterase type 5 inhibitor, prevents post cardiac surgery AKI in pre-clinical studies, however its use is contraindicated in patients with symptomatic cardiovascular disease. METHODS: To assess the safety and pharmacokinetics of intravenous sildenafil in cardiac surgery patients we conducted an open label, dose escalation study with 6 patients per dose level...

Anemia is an independent risk factor for adverse patient outcomes. There are no guidelines for management of anemia in patients withcongestive heart failure (CHF), despite itshigh incidence. Four objectives were defined by the International Anemia Management and Clinical Outcomes Expert Panel (AMCO), a multinational group of interdisciplinary experts identified by the Society for the Advancement of Blood Management (SABM) to: determine the prevalence of anemia in outpatients; to determine the prevalence of hospital-acquired anemia; to assess the impact of anemia management on clinical outcomes such as quality of life and functional status; and to provide recommendations for primary care physicians and specialists for the diagnosis, evaluation, and management of anemia in patients with CHF...

In contrast to hepatocyte growth factor (HGF), the therapeutic potential and pathophysiologic roles of heparin-binding epidermal growth factor-like growth factor (HB-EGF) in liver diseases remain relatively unknown. To address the lack of effective pharmacologic treatments for cholestatic liver injuries, as well as to clarify the biologic features of these growth factors, we explored the effects of HB-EGF and HGF in mice with cholestatic liver injury induced by bile duct ligation (BDL). The mice were assessed 3, 5 and/or 14 days after BDL (acute, subacute and/or chronic phases, respectively) and intravenous injection of adenoviral vector expressing LacZ (control), HB-EGF, HGF, or HB-EGF and HGF...

BACKGROUND: Fat embolism (FE) and the consequent fat embolism syndrome (FES) occurring after trauma or surgery can lead to serious pulmonary injury, including ARDS and death. Current treatment of FES is limited to supportive therapy. We have shown in a rat model that the renin angiotensin system (RAS) plays a significant role in the pathophysiology of FE since drugs interfering with the RAS, captopril and losartan, reduce the histopathologic pulmonary damage. The purpose of the current study was to determine if inhibition of renin by aliskiren, an FDA-approved drug for treating hypertension, would produce effective protection in the same model...

INTRODUCTION: Prehospital, small-volume resuscitation of combat casualties with a synthetic colloid [6% hydroxyethyl starch (HES) 670/0.75] has been recommended when blood or blood components are unavailable. We studied hemostatic effects of a newer synthetic colloid (6% HES 130/0.4,) compared to either a natural colloid (albumin) or to crystalloids in an uncontrolled hemorrhage model. METHODS: Spontaneously breathing NZW rabbits (3.4±0.1 kg) were anesthetized, instrumented and subjected to a splenic injury with uncontrolled bleeding...

BACKGROUND: Few pharmacokinetic (PK) and pharmacodynamic (PD) data exist for COX-2 selective inhibitors in children. We wished to characterize the PKPD of parecoxib and its active metabolite, valdecoxib, in this population. METHODS: Children (n = 59) were randomized to parecoxib 0.25 mg·kg(-1) , 1 mg·kg(-1) , and 2 mg·kg(-1) during tonsillectomy ± adenoidectomy. Samples (4-6 per child) were obtained from indwelling cannula over 6 h. A second group of inpatient children (n = 15) given 1 mg·kg(-1) contributed PK data from 6 to 24 h...

BACKGROUND: Mortality following surgical repair of congenital diaphragmatic hernia (CDH) remains high. The volume and type of perioperative intravenous fluid administered, baro-trauma, oxygen toxicity, and the duration of anesthesia are thought to affect outcome in surgical populations. AIMS: The aim of this retrospective observational study was to determine whether the perioperative volume or type of fluids and/or the duration of anesthesia were associated with postoperative mortality and if mortality was predicted by the oxygenation index (OI) prior to or following CDH surgical repair...

BACKGROUND: Dexmedetomidine is a selective alpha-2 adrenergic agonist with sedative, analgesic, and anxiolytic properties. Dexmedetomidine has not been approved for use in pediatrics. Dexmedetomidine has been reported to depress sinus node and atrioventricular nodal function in pediatric patients; it has been suggested that the use of dexmedetomidine may not be desirable during electrophysiological studies. AIM: We hypothesize that the use of dexmedetomidine does not inhibit the induction of supraventricular tachyarrhythmias (SVT) during electrophysiological studies and does not inhibit the ablation of such arrhythmias...

Sinusoidal obstruction syndrome (SOS) is a severe complication of hematopoietic stem cell transplantation (HSCT) that can be fatal, often attributed to the conditioning regimen prior to HSCT. We evaluated the association of SOS risk with gene variants in cystathionase (CTH), an enzyme involved in glutathione synthesis, in 76 children receiving intravenous busulfan (Bu) before HSCT. Our results indicated an association with CTHc.1364 G>T (ORTT=10.6, 95% confidence interval (CI)=2.16, 51.54) and SOS risk, which was sex dependent (female patients, ORTT=21...
