Survival outcomes of patients with diffuse large B-cell lymphoma undergoing autologous stem cell transplantation in Germany: real-world evidence from an administrative database between 2010 and 2019.

Background: Limited real-world evidence is available for patients with diffuse large B-cell lymphoma (DLBCL) who received an autologous stem cell transplantation (ASCT) in Germany.

Objectives: This study aims to describe the real-world survival outcomes of patients with DLBCL who received ASCT in Germany after diagnosis.

Design: This study is a retrospective database analysis covering the period between 2010 and 2019.

Unveiling the untreated: development of a database algorithm to identify potential Fabry disease patients in Germany.

Background: Fabry disease (FD), an X-linked lysosomal storage disorder, is caused by mutations in the gene encoding α-galactosidase A, resulting in lysosomal accumulation of globotriaosylceramide and other glycosphingolipids. Early detection of FD is challenging, accounting for delayed diagnosis and treatment initiation. This study aimed to develop an algorithm using a logistic regression model to facilitate early identification of patients based on ICD-10-GM coding using a German Sickness Fund Database.

Healthcare Resource Utilization and Associated Costs of German Patients with Diffuse Large B-Cell Lymphoma: A Retrospective Health Claims Data Analysis.

Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkin's lymphoma with increasing prevalence. Although the disease burden associated with DLBCL is high, only limited data on healthcare resource utilization (HCRU) and associated costs of German patients with DLBCL is available.

Methods: Using a large claims database of the German statutory health insurance with 6.

Spectral recording of gene expression history by fluorescent timer protein.

Monitoring spatio-temporal patterns of gene expression by fluorescent proteins requires longitudinal observation, which is often difficult to implement. Here, we fuse a fluorescent timer (FT) protein with an immediate early gene (IEG) promoter to track live gene expression in single cells. This results in a stimulus- and time-dependent spectral shift from blue to red for subsequent monitoring with fluorescence activated cell sorting (FACS) and live cell imaging.

Correlation of Cytomegalovirus (CMV) Disease Severity and Mortality With CMV Viral Burden in CMV-Seropositive Donor and CMV-Seronegative Solid Organ Transplant Recipients.

Background: The rate of cytomegalovirus (CMV) viral load increase and peak viral loads are associated with CMV disease in kidney and liver transplant recipients, but relationships to disease severity or mortality have not been shown.

Methods: Using stored serial serum specimens from renal (n = 59) and liver (n = 35) transplant recipients (D+R-; CMV-seropositive donors, CMV-seronegative recipients) from 2 prospective, randomized, controlled, interventional prophylaxis trials of CMV immune globulin (CMVIG), CMV viral load was measured using the COBAS quantitative polymerase chain reaction assay and the World Health Organization CMV standard. Patients with severe CMV-associated disease were classified according to trial definitions.

Central amygdala circuit dynamics underlying the benzodiazepine anxiolytic effect.

Benzodiazepines (BZDs) have been a standard treatment for anxiety disorders for decades, but the neuronal circuit interactions mediating their anxiolytic effect remain largely unknown. Here, we find that systemic BZDs modulate central amygdala (CEA) microcircuit activity to gate amygdala output. Combining connectome data with immediate early gene (IEG) activation maps, we identified the CEA as a primary site for diazepam (DZP) anxiolytic action.

Molecular role of the PAX5-ETV6 oncoprotein in promoting B-cell acute lymphoblastic leukemia.

PAX5 is a tumor suppressor in B-ALL, while the role of PAX5 fusion proteins in B-ALL development is largely unknown. Here, we studied the function of PAX5-ETV6 and PAX5-FOXP1 in mice expressing these proteins from the locus. Both proteins arrested B-lymphopoiesis at the pro-B to pre-B-cell transition and, contrary to their proposed dominant-negative role, did not interfere with the expression of most regulated Pax5 target genes.

Acute infections, cost and time to reporting of HIV test results in three U.S. State Public Health Laboratories.

Objective: In three U.S. State Public Health Laboratories (PHLs) using a fourth-generation immunoassay (IA), an HIV-1/HIV-2 differentiation antibody IA and a nucleic acid test (NAT), we characterized the yield and time to reporting of acute infections, and cost per positive specimen.

Mutations in the murine homologue of TUBB5 cause microcephaly by perturbing cell cycle progression and inducing p53-associated apoptosis.

Microtubules play a crucial role in the generation, migration and differentiation of nascent neurons in the developing vertebrate brain. Mutations in the constituents of microtubules, the tubulins, are known to cause an array of neurological disorders, including lissencephaly, polymicrogyria and microcephaly. In this study we explore the genetic and cellular mechanisms that cause TUBB5-associated microcephaly by exploiting two new mouse models: a conditional E401K knock-in, and a conditional knockout animal.

Acute Infections, Cost per Infection and Turnaround Time in Three United States Hospital Laboratories Using Fourth-Generation Antigen-Antibody Human Immunodeficiency Virus Immunoassays.

Background.  To improve clinical and public health outcomes through early human immunodeficiency virus (HIV) detection, fourth-generation antigen/antibody immunoassay (4IA) and supplemental testing results must be returned rapidly. Methods.

Nucleic acid testing by public health referral laboratories for public health laboratories using the U.S. HIV diagnostic testing algorithm.

Background: Many public health laboratories adopting the U.S. HIV laboratory testing algorithm do not have a nucleic acid test (NAT), which is needed when the third- or fourth-generation HIV screening immunoassay is reactive and the antibody-based supplemental test is non-reactive or indeterminate.

Stage-specific control of early B cell development by the transcription factor Ikaros.

The transcription factor Ikaros is an essential regulator of lymphopoiesis. Here we studied its B cell-specific function by conditional inactivation of the gene encoding Ikaros (Ikzf1) in pro-B cells. B cell development was arrested at an aberrant 'pro-B cell' stage characterized by increased cell adhesion and loss of signaling via the pre-B cell signaling complex (pre-BCR).

4th generation HIV screening in Massachusetts: a partnership between laboratory and program.

Background: The Massachusetts Department of Public Health's (MDPH) Office of HIV/AIDS (OHA) and Hinton State Laboratory Institute (HSLI) have offered HIV screening since 1985. Point-of-care screening and serum collection for laboratory-based testing is conducted at clinic and non-clinic-based sites across Massachusetts as part of an integrated communicable disease screening intervention.

Objectives And Project Design: MDPH aimed to transition to a 4th generation HIV screening-based algorithm for testing all serum specimens collected at OHA-funded programs and submitted to the HSLI to detect acute HIV infections, detect and differentiate HIV-1 and HIV-2 infections, eliminate indeterminate results, reduce cost and turnaround time, and link newly diagnosed HIV+ individuals to care.

Essential role of EBF1 in the generation and function of distinct mature B cell types.

The transcription factor EBF1 is essential for lineage specification in early B cell development. In this study, we demonstrate by conditional mutagenesis that EBF1 is required for B cell commitment, pro-B cell development, and subsequent transition to the pre-B cell stage. Later in B cell development, EBF1 was essential for the generation and maintenance of several mature B cell types.

Signs Observed Among Animal Species Infected with Raccoon Rabies Variant Virus, Massachusetts, USA, 1992-2010.

We analyzed signs occurring among domestic and wild terrestrial animal species infected with raccoon rabies variant virus (RRV) in Massachusetts, 1992-2010. The clinical sign of aggression was significantly associated with rabid stray cats (odds ratio, OR = 2.3) and RRV affected major wild terrestrial animal species individually, which included raccoons (OR = 2.

Increased serum iron levels and infectious complications after liver transplantation.

Background: Elevated serum iron levels have been associated with infectious outcomes in various patient populations but, to our knowledge, have never been studied after liver transplantation.

Methods: The relationship between serum iron levels and infectious outcomes after liver transplantation was evaluated in a nested case-control study using prospectively collected data and serum samples. Unadjusted and adjusted hazard ratios were calculated for each iron marker predictor variable (iron level, unsaturated iron-binding capacity, total iron-binding capacity, transferrin saturation, and ferritin level) and time to development of each of 6 outcomes (cytomegalovirus [CMV] disease, invasive fungal infection, bacteremia, invasive fungal infection or bacteremia, any infection, and 1-year mortality rate).

Animal rabies in Massachusetts, 1985-2006.

In this study, we review annual rabies data from Massachusetts from 1985 to 2006, spanning the introduction of raccoon strain rabies in 1992. Of 52,034 animals tested, 9.7% (5,049/52,034) were rabid, representing 26 of over 67 species submitted.

Human eastern equine encephalitis in Massachusetts: predictive indicators from mosquitoes collected at 10 long-term trap sites, 1979-2004.

Human eastern equine encephalitis (EEE) is a life-threatening mosquito-borne disease. To determine whether mosquito abundance and EEE virus infection rates are associated with human EEE disease, we evaluated retrospectively a total of 592,637 mosquitoes and onset dates for 20 confirmed human cases over 26 years in Massachusetts. Annual Culiseta melanura populations at 10 defined sites decreased over the study period (P = 0.

Implementing a routine, voluntary HIV testing program in a Massachusetts county prison.

Although U.S. prison inmates have higher rates of HIV infection than the general population, most inmates are not routinely tested for HIV infection at prison entry.

Hypogammaglobulinemia in liver transplant recipients: incidence, timing, risk factors, and outcomes.

Background: Recent studies suggest a substantial incidence of posttransplant hypogammaglobulinemia and an association with infection.

Methods: We conducted a retrospective analysis of immunoglobulin (Ig) G levels from blood prospectively collected during a randomized double-blind placebo-controlled trial of cytomegalovirus (CMV) immune globulin that included 146 patients who underwent liver transplantation between December 1987 and June 1990. Serum samples collected at baseline and approximately weeks 4, 8, 12, 16, 24, and 32 posttransplant were analyzed.

Drug-selected resistance mutations and non-B subtypes in antiretroviral-naive adults with established human immunodeficiency virus infection.

The prevalence of human immunodeficiency virus (HIV) type 1 antiretroviral resistance is expected to be higher in recently infected antiretroviral-naive individuals than in those who have been infected longer. Antiretroviral-naive HIV-1-infected adults who presented to an outpatient clinic in an urban hospital in Boston for initial evaluation in 1999 were screened for drug-selected resistance mutations and phylogenetic subtype. Drug-selected mutations were identified in 16 (18%) of 88 subjects.

Histopathologically proven poliomyelitis with quadriplegia and loss of brainstem function due to West Nile virus infection.

Recent electrophysiological and histopathological reports point to motor neurons in the anterior horn of the spinal cord and the brainstem as targets of severe West Nile virus (WNV) infection. We report histopathological confirmation of this poliomyelitis-like syndrome in a patient with WNV infection in Massachusetts.
