Furosemide for patent ductus arteriosus during cyclooxygenase inhibitor therapy: A systematic review.

Background: Although furosemide is used during cyclooxygenase (COX) inhibitor therapy for patent ductus arteriosus (PDA), there are concerns regarding increased ductal closure failure and acute renal failure (ARF). This systematic review explores the effects of furosemide during COX inhibitor therapy.

Methods: We searched MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi databases for randomized clinical trials that assessed furosemide during COX inhibitor therapy for PDA in preterm infants.

Safety and efficacy of satralizumab monotherapy in neuromyelitis optica spectrum disorder: a randomised, double-blind, multicentre, placebo-controlled phase 3 trial.

Background: Satralizumab, a humanised monoclonal antibody targeting the interleukin-6 receptor, reduced the risk of relapse in patients with neuromyelitis optica spectrum disorder (NMOSD) when added to immunosuppressant therapy. This study assessed the safety and efficacy of satralizumab monotherapy in patients with the disorder.

Methods: In this phase 3, double-blind, placebo-controlled, parallel-group trial, we enrolled adults aged 18-74 years with aquaporin-4 antibody seropositive or seronegative NMOSD at 44 investigational sites in 13 countries.

Therapeutic Drug Monitoring Simulator for Antibiotic Dosage for Methicillin-Resistant Staphylococcus aureus Sepsis in a Patient with Primary Immunodeficiency on Peritoneal Dialysis.

Bacterial infections often cause fatal systemic infections in patients with primary immunodeficiency. To prevent unfortunate results, the selection, dose, and dosage of antibiotics are extremely important. Here, we report a case of Wiskott-Aldrich syndrome in a patient undergoing peritoneal dialysis because of chronic renal failure in whom methicillin-resistant Staphylococcus aureus sepsis developed.

Trisomy 13 and massive fetomaternal hemorrhage.

This is the first case report of trisomy 13 complicated by massive fetomaternal hemorrhage (FMH). A pale male infant weighing 2,950 g was delivered with low Apgar scores by emergency cesarean section due to non-reassuring fetal status. The umbilical arterial pH and hemoglobin level were 6.

Intestinal P-glycoprotein expression is multimodally regulated by intestinal ischemia-reperfusion.

Purpose: Reactive oxygen species (ROS) have multiple physiological effects that are amount-dependent. ROS are one of the causes of intestinal ischemia-reperfusion (I/R) injury. In this study, we investigated whether the amount of ROS and the degree of intestinal I/R injury affect the expression level of P-glycoprotein (P-gp).

Bifid scrotum and anocutaneous fistula associated with a perineal lipomatous tumor complicated by temporary bilateral cryptorchidism in utero mimicking ambiguous genitalia: 2-D/3-D fetal ultrasonography.

Ambiguous genitalia (AG) is a morphological diagnosis defined as genitalia not typical of a male or female. Findings mimicking AG, such as penoscrotal anomalies, anorectal malformations, and perineal lipomatous tumors, may prevent accurate identification of the fetal sex. We report a case of bifid scrotum and anocutaneous fistula associated with a perineal lipomatous tumor complicated by temporary bilateral cryptorchidism in utero, which were findings mimicking AG.

Effect of oxidative stress on expression and function of human and rat organic anion transporting polypeptides in the liver.

Reactive oxygen species (ROS) have physiological function and involve alteration of physical state. However, it is not clear effect of oxidative stress on pharmacokinetics. Organic anion transporting polypeptides (human: OATPs, rodent: Oatps) are important for uptake of endogenous and exogenous compounds into hepatocytes.

Intestinal ischemia-reperfusion suppresses biliary excretion of hepatic organic anion transporting polypeptides substrate.

Purpose: Intestinal ischemia-reperfusion (I/R) causes gut dysfunction and promotes multi-organ failure. The liver and kidney can be affected by multi-organ failure after intestinal I/R. Organic anion transporting polypeptides (OATPs) and organic anion transporters (OATs) are recognized in a broad spectrum from endogenous compounds to xenobiotics, including clinically important drugs.

The decrease in farnesoid X receptor, pregnane X receptor and constitutive androstane receptor in the liver after intestinal ischemia-reperfusion.

Purpose: Intestinal ischemia-reperfusion (I/R) damages remote organs, including the liver, and promotes multi-organ failure (MOF). However, the molecular mechanisms underlying acute liver injury after intestinal I/R have not been completely elucidated. Farnesoid X receptor (FXR), pregnane X receptor (PXR) and constitutive androstane receptor (CAR) regulate metabolizing enzymes and transporters, and coordinately prevent hepatotoxicity reflecting an inability of appropriate excretion of endogenous toxic compounds.

Intestinal ischemia-reperfusion increases efflux for uric acid via paracellular route in the intestine, but decreases that via transcellular route mediated by BCRP.

Purpose: Uric acid is thought to be one of the most important antioxidants in human biological fluids. Intestinal ischemia-reperfusion (I/R) is an important factor associated with high rates of morbidity and mortality. Reactive oxygen species (ROS) are responsible for intestinal I/R injury.
