    The demanding attention of tuberculosis in allogeneic hematopoietic stem cell transplantation recipients: High incidence compared with general population

    No full text
    The risk of developing tuberculosis (TB) in allogeneic hematopoietic stem cell transplantation (HSCT) recipients is expected to be relatively high in an intermediate TB burden country. This single-center retrospective study was conducted to investigate risk factors and the incidence of TB after allogeneic HSCT.From January 2004 to March 2011, 845 adult patients were enrolled. Starting April 2009, patients were given isoniazid (INH) prophylaxis based on interferon-γ release assay results. The incidence of TB was analyzed before and after April 2009, and compared it with that of the general population in Korea. = 0.548). Among 21 TB patients, one patient had INH prophylaxis.Allogeneic HSCT recipients especially those who suffer from extensive chronic GVHD are at a high risk of developing TB. INH prophylaxis did not statistically change the incidence of TB, however, further well-designed prospective studies are needed

    Correlated 5-Hydroxymethylcytosine (5hmC) and Gene Expression Profiles Underpin Gene and Organ-Specific Epigenetic Regulation in Adult Mouse Brain and Liver

    No full text
    DNA methylation is an epigenetic mechanism essential for gene regulation and vital for mammalian development. 5-hydroxymethylcytosine (5hmC) is the first oxidative product of the TET-mediated 5-methylcytosine (5mC) demethylation pathway. Aside from being a key intermediate in cytosine demethylation, 5hmC may have potential regulatory functions with emerging importance in mammalian biology.Here, we investigate the global 5hmC enrichment in five brain structures, including cerebellum, cerebral cortex, hippocampus, hypothalamus and thalamus, as well as liver tissues from female and male adult mice by using chemical capture-based technique coupled with next-generation sequencing. At the same time, we carried out total RNA sequencing (RNA-seq) to analyze the transcriptomes of brain regions and liver tissues.) gene located on the X chromosome is the only gene to show sex-specific 5hmC enrichment.This is the first report of the whole-genome 5hmC methylome of five major brain structures and liver tissues in mice of both sexes. This study offers a comprehensive resource for future work of mammalian cytosine methylation dynamics. Our findings offer additional evidence that suggests 5hmC is an active epigenetic mark stably maintained after the global reprogramming event during early embryonic development

    HIV drug therapy duration; a Swedish real world nationwide cohort study on InfCareHIV 2009-2014

    No full text
    As HIV infection needs a lifelong treatment, studying drug therapy duration and factors influencing treatment durability is crucial. The Swedish database InfCareHIV includes high quality data from more than 99% of all patients diagnosed with HIV infection in Sweden and provides a unique opportunity to examine outcomes in a nationwide real world cohort. agent (all antiretrovirals that are not N[t]RTIs) 2009–2014 with more than 100 observations in treatment-naive or treatment-experienced patients were included. Dolutegravir was excluded due to short follow up period. Multivariate Cox proportional hazards models were used to estimate hazard ratios for treatment discontinuation. agent chosen also certain baseline characteristics of patients were independently associated with differences in treatment duration. In naive patients, presence of an AIDS-defining diagnosis and the use of other backbone than TDF/FTC or ABC/3TC increased the risk for early treatment discontinuation. In treatment-experienced patients, detectable plasma viral load at the time of switch or being highly treatment experienced increased the risk for early treatment discontinuation. agent has a strong impact and significant differences between different drugs on treatment duration exist
