BACKGROUND: While survey data are available for national estimates of fire events and firefighter fatalities, data on firefighter injury at the national and local levels remain incomplete and unreliable. Data linkage provides a vehicle to maximise case detection and deepen injury description for the US fire service. METHODS: By linking departmental Human Resources records, despatch data, workers' compensation and first reports of injury, researchers were able to describe reported non-fatal injuries to 3063 uniformed members of the Philadelphia Fire Department (PFD), for the period of 2005 through 2013...

Tyrosine kinase inhibitors (TKI) are the mainstay treatment of BCR-ABL1-positive leukemia and virtually all patients with chronic myeloid leukemia in chronic phase (CP CML) respond to TKI therapy. However, there is limited information on the cellular mechanisms of response and particularly on the effect of cell differentiation state to TKI sensitivity in vivo and ex vivo/in vitro. We used multiple, independent high-throughput drug sensitivity and resistance testing platforms that collectively evaluated 295 oncology compounds to characterize ex vivo drug response profiles of primary cells freshly collected from newly-diagnosed patients with BCR-ABL1-positive leukemia (n = 40) and healthy controls (n = 12)...

PURPOSE: Ponatinib is a novel tyrosine kinase inhibitor (TKI) specifically designed to inhibit native and mutated BCR-ABL. In the United States, ponatinib has received accelerated approval for adults with T315I-positive chronic myeloid leukemia (CML) or T315I (gatekeeper mutation)-positive, Philadelphia chromosome-positive, acute lymphoblastic leukemia (Ph + ALL), and patients with CML or Ph + ALL for whom no other TKI therapy is indicated. The objective of this phase 1, mass balance study was to evaluate the absorption, metabolism, and excretion of [(14)C]ponatinib in healthy subjects...

Bispecific T Cell Engagers (BiTE®) antibody constructs enable a polyclonal T cell response to cell-surface tumor-associated antigens, bypassing the narrow specificities of T cell receptors and the need for antigen presentation through the Major Histocompatibility Complex pathways. Blinatumomab, a CD19xCD3 BiTE® antibody construct, received accelerated approval for the treatment of relapsed/refractory Philadelphia chromosome negative acute lymphoblastic leukemia. Herein we review the pharmacology, safety, and efficacy observed in studies of blinatumomab and other BiTE® antibody constructs...

INTRODUCTION: Despite evidence that regular physical activity confers health benefits, physical activity rates among older adults remain low. Both personal and social goals may enhance older adults' motivation to become active. This study tested the effects of financial incentives, donations to charity, and the combined effects of both interventions on older adults' uptake and retention of increased levels of walking. STUDY DESIGN: RCT comparing three interventions to control...

In this issue of the American Journal of Hematology, Weinberg et al.(1) discuss how multiple diagnostic techniques should be integrated in the diagnosis of acute myeloid leukemia (AML) and the risk stratification of patients.Ever since the discovery of Philadelphia chromosome more than 50 years ago(2) , conventional cytogenetic assays, including karyotype and fluorescent in situ hybridization (FISH), have played a critical role in classification, diagnosis and management of AML and other myeloid neoplasms. Most, if not all, of the recurrent chromosomal rearrangements commonly seen in AML are now well-described and the genes involved in these rearrangements have been identified...

Unlike chronic myeloid leukemia, patients with acute lymphoblastic leukemia (ALL) with Philadelphia chromosome (Ph+) do not respond well to Imatinib or tyrosine kinase inhibitors (TKI). In addition, TKI might induce resistant mutations in kinase domain (KD) of ABL in patients with relapsed diseases. Of the histone deacetylase (HDAC) inhibitors, suberoylanilide hydroxamic acid (SAHA) has shown to induce potent cytotoxicity on acute myeloid leukemia cell lines but Givinostat effect on acute lymphoblastic leukemia (ALL) has not been reported...

PURPOSE: Proton dose distribution is sensitive to tumor regression and tissue and normal anatomy changes. Replanning is sometimes necessary during treatment to ensure continue tumor coverage or avoid overtreatment of organs at risk (OARs). We investigated action thresholds for replanning and identified both dosimetric and non-dosimetric metrics that would predict a need for replan. METHODS: All consecutive lung cancer patients (n = 188) who received definitive proton radiotherapy and had more than two evaluation CT scans at the Roberts Proton Therapy Center (Philadelphia, USA) from 2011 to 2015 were included in this study...

INTRODUCTION: The Philadelphia chromosome (Ph) is the most common cytogenetic abnormality associated with adult acute lymphoblastic leukemia (ALL) occurring in 20% to 40% of patients. It is also detected in 2% to 5% of children with ALL. Historically, patients with Ph-positive ALL carried a dismal prognosis, with poor response to most chemotherapy combinations, short remission durations, and long-term disease-free survival rates of 10% to 20%. The advent of tyrosine kinase inhibitors (TKIs) has revolutionized therapy of Ph-positive ALL...

BACKGROUND: Hypoplastic right heart syndrome (HRHS) is a rare congenital defect characterized by underdevelopment of the right heart structures commonly accompanied by an atrial septal defect. Familial HRHS reports suggest genetic factor involvement. We examined the role of copy number variants (CNVs) in HRHS. METHODS: We genotyped 32 HRHS cases identified from all New York State live births (1998-2005) using Illumina HumanOmni2.5 microarrays. CNVs were called with PennCNV and prioritized if they were ≥20 Kb, contained ≥10 SNPs and had minimal overlap with CNVs from in-house controls, the Database of Genomic Variants, HapMap3, and Childrens Hospital of Philadelphia database...

In patients with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) treated with chemotherapy plus a tyrosine kinase inhibitor (TKI), the prognostic impact of additional chromosomal abnormalities (ACAs) is not well-established. We evaluated the prognostic impact of individual ACAs in 152 patients with Ph+ ALL receiving first-line intensive chemotherapy plus either imatinib (n=36), dasatinib (n=74) or ponatinib (n=42). ACAs were identified in 118 patients (78%). Compared to outcomes of patients without ACAs, ACAs were not associated with differences in either relapse-free survival (RFS; P=0...
