Background: In the fifth National Wilms Tumor Study, patients received vincristine and dactinomycin (VA) without radiation for stage I focal anaplastic Wilms tumor (FAWT) and VA plus doxorubicin (DD4A) and radiation for stage II-IV FAWT. Four-year event-free survival (EFS) and overall survival (OS) for stage I FAWT were 67.5% and 88.

Apnea After 2-Month Vaccinations in Hospitalized Preterm Infants: A Randomized Clinical Trial.

Importance: Preterm infants are recommended to receive most vaccinations at the same postnatal age as term infants. Studies have inconsistently observed an increased risk for postvaccination apnea in preterm infants.

Objective: To compare the proportions of hospitalized preterm infants with apnea and other adverse events in the 48 hours after 2-month vaccinations vs after no vaccinations.

Imaging Findings and Management Strategies for Liver Masses in Children with Predisposition Disorders: A Review by the Pediatric LI-RADS Group.

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.

Resolution of chyluria due to congenital malformation with a minimally invasive procedure.

Milky white urine is most commonly due to chyluria secondary to filariasis, though other causes of milky white urine and other etiologies of chyluria must be considered. Evaluation of a 3-year-old girl with milky white urine demonstrated chyluria, but testing for filariasis was negative despite a history of travel to an endemic region. Magnetic resonance lymphangiography demonstrated a congenital lymphatic malformation, which was repaired following this minimally invasive imaging technique.

Differential Effects of Four Canonical Notch-Activating Ligands on c-Kit+ Cardiac Progenitor Cells.

Notch signaling, an important signaling pathway in cardiac development, has been shown to mediate the reparative functions of c-kit+ progenitor cells (CPCs). However, it is unclear how each of the four canonical Notch-activating ligands affects intracellular processes in c-kit+ cells when used as an external stimulus. Neonatal c-kit+ CPCs were stimulated using four different chimeric Notch-activating ligands tethered to Dynabeads, and the resulting changes were assessed using TaqMan gene expression arrays, with subsequent analysis by principal component analysis (PCA).

Effects of hyperglycemia on airway epithelial barrier function in WT and CF 16HBE cells.

Cystic fibrosis related diabetes (CFRD), the main co-morbidity in cystic fibrosis (CF), is associated with higher rates of lung function decline. We hypothesize that airway epithelial barrier function is impaired in CF and is further exacerbated under hyperglycemia, worsening pulmonary outcomes. Using 16HBE cells, we studied the effects of hyperglycemia in airway epithelial barrier function.

Incidence of bacterial blood stream infections in patients with acute GVHD.

Bacterial bloodstream infections (BSI) can be a substantial contributor to complications of GVHD treatment. The aim of this study was to determine the risk for BSI from neutrophil engraftment through day 100 post transplant in patients with acute GVHD (AGVHD) based on organ involvement and severity. Patients (n = 4064) who underwent an allogeneic hematopoietic stem cell transplant (HCT) reported to the CIBMTR registry were analyzed.

Real-world effectiveness of eptacog beta in patients with haemophilia and inhibitors: A multi-institutional case series.

Introduction: The management of bleeding events (BEs) in haemophilia A (HA) and B (HB) patients with inhibitors necessitates the use of bypassing agents. The recombinant factor VIIa bypassing agent eptacog beta has demonstrated efficacy at treating BEs and managing perioperative bleeding in adults in phase three clinical studies.

Aim: To provide real-world descriptions of eptacog beta use for BE treatment in patients on emicizumab or eptacog beta prophylaxis.

Comparative clinical efficacy and safety of biosimilar ABP 959 and eculizumab reference product in patients with paroxysmal nocturnal hemoglobinuria.

ABP 959 is a biosimilar to the eculizumab reference product (RP), which is approved for the treatment of patients with paroxysmal nocturnal hemoglobinuria (PNH). This multicenter, randomized, double-blind, active-controlled, two-period crossover study randomized eculizumab RP-treated patients with PNH to one of two treatment sequences (ABP 959/eculizumab RP or eculizumab RP/ABP 959) to evaluate the clinical similarity of ABP 959 when compared with eculizumab RP. This study evaluated the efficacy of ABP 959 when compared with eculizumab RP based on control of intravascular hemolysis as measured by lactate dehydrogenase (LDH) and by the time-adjusted area under the effect curve of LDH.
