Transplant-associated thrombotic microangiopathy (TA-TMA) is a severe complication following hematopoietic stem cell transplantation (HSCT). No approved treatments are currently available. This study presents real-world data obtained with narsoplimab, a human immunoglobulin G4 monoclonal antibody that inhibits MASP-2, the effector enzyme of the lectin pathway of the complement system.

Recognized for its speed and selectivity, HPLC enables direct analysis of intracerebral microdialysis samples without complex derivatization. Various chromatographic methods, including reverse phase (RP), are explored for neurotransmitters (NTs) and metabolites separation.

Clinical use of genomic profiling provides an opportunity to identify targetable alterations to inform therapy.
Experimental Design: We describe a cohort of 14 pediatric patients with relapsed or refractory T-ALL enrolled on the Leukemia Precision-based Therapy (LEAP) Consortium trial (NCT02670525) and a patient with T-LBL, discovering alterations in platelet-derived growth factor receptor-α (PDGFRA) in 3 of these patients.
Several lattice models display a condensation transition in real space when the density of a suitable order parameter exceeds a critical value. We consider one of such models with two conservation laws, in a onedimensional open setup where the system is attached to two external reservoirs. Both reservoirs impose subcritical boundary conditions at the chain ends.

Currently, different ASP products are available in the market, including both native and pegylated drugs. Several biogeneric Escherichia coli ASP (GEN-ASP) products have been developed in response to shortages and expensiveness of the native E.

The frequency, predictors, and prognostic impact of OA in the context of recent ALL protocols are not well characterized.
Procedure: Single-center retrospective analysis of the medical records of 224 patients with ALL enrolled on Dana-Farber Cancer Institute (DFCI) ALL Consortium Protocol 05-001.
Adolescent and young adult patients with acute lymphoblastic leukemia (ALL) have superior outcomes when treated on pediatric regimens. Pediatric ALL regimens rely heavily on corticosteroids and asparaginase and are known to increase the risk of osteonecrosis (ON) and fractures in children, particularly adolescents. Orthopedic toxicity among young adults treated on pediatric-inspired regimens is not well described.

We numerically study the dependence of the participation ratio Y_{2}=〈ε_{i}^{2}〉/(Nh^{2}) on the size N of the system and on the control parameter δ=(h-h_{c}), for various models: (i) a model with two conservation laws, derived from the discrete nonlinear Schrödinger equation; (ii) the continuous version of the zero-range process class, for different forms of the function f(ε) defining the factorized steady state. Our results show that various localization scenarios may appear for finite N and close to the transition point.

We report the feasibility of rapid identification of targetable mutations in 153 pediatric patients with relapsed/refractory or high-risk leukemias enrolled on a prospective clinical trial conducted by the LEAP Consortium. Eighteen percent of patients had a high confidence Tier 1 or 2 recommendation.

Although the relationship of action potential (AP) firing and metabolism is firmly established, there is no single method to differentiate interneurons in situ based on their firing properties. In this study, we explore a novel strategy to easily identify the metabolically active FS cells among different classes of interneurons.

Although the pathomechanisms of this disease remain unclear, oxidative stress induced by NMDA receptor (NMDAR) hypofunction and decreased glutathione (GSH) synthesizing capacity have been shown to lead to PV-loss and aberrant oscillatory activity. However, the individual contributions of NMDAR-inhibition and GSH-depletion to the developmental alterations observed in schizophrenia are largely unknown.

Materials And Methods: A never-smoker female with primary EGFR/KRAS/ALK-negative squamous cell carcinoma of the lung and their normal sibswere subjected to a novel integrative "omic" approach using a pedigree-based model for discovering genetic factors leading to cancer in the absence of well-known environmental trigger.
Congenital defects of the sternum are rare and due to a failure of midline development and fusion of the sternal bones. Surgical correction of a sternal cleft should be preferred during infancy for functional reasons. Chest wall reconstruction represented a complex problem in the last decades.

In these disorders, the clinical presentation includes jaundice, pale stools, dark urine and hepatomegaly. Splenomegaly is not an early feature since it is due to portal hypertension, a later event.

Regarding eNO and eCO levels in LTX patients affected by bronchiolitis obliterans syndrome (BOS), published data are discordant.
Objectives: We aim to evaluate eNO at multiple flows, alveolar concentration of nitric oxide (CalvNO), maximum conducting airway wall flux (J'awNO) and eCO levels in LTX patients to assess the potential role of these parameters in BOS evaluation.
Background: Many reports emphasize the role of sub-lobar resections in the treatment of small peripheral lung cancer. The aim of this study was to investigate a range of prognostic factors, including the extension of resection, which may affect the prognosis in a homogeneous group of patients.
Methods: We retrospectively reviewed the clinical records of 279 patients affected by N0 small peripheral adenocarcinoma (ADK) <3 cm that underwent surgery between 2000 and 2010.
Introduction: Atypical teratoid/rhabdoid tumor (AT/RT) of the central nervous system is a highly aggressive neoplasm which prevalently affects children and is characterized by a severe prognosis.
Case Presentation: The authors describe an extremely rare case of a primary spinal AT/RT that occurred in a young girl. The patient underwent a wide surgical resection of a lumbar mass, followed by aggressive chemotherapy, myeloablative treatment, and local radiotherapy.
The aim of this study was to assess long-term pulmonary and diaphragmatic function in two cohorts of patients: the first one affected by diaphragmatic palsy (DP) who underwent plication reinforced by rib-fixed mesh and the second one affected by chronic diaphragmatic hernia (TDH) who underwent surgical reduction and direct suture. From 1996 to 2011, 10 patients with unilateral DP and 6 patients with TDH underwent elective surgery. Preoperative and long-term (12 months) follow-up assessments were completed in all patients, including pulmonary function tests (PFTs) with diffusion of the lung for carbon monoxide (DLCO), measure of maximum inspiratory pressure (MIP) assessed both in standing and in supine positions, blood gas analysis, chest computed tomographic (CT) scan, and dyspnea score.
