    Common genetic variants contribute to the observed variation in breast cancer risk for BRCA2 mutation carriers; those known to date have all been found through population-based genome-wide association studies (GWAS). To comprehensively identify breast cancer risk modifying loci for BRCA2 mutation carriers, we conducted a deep replication of an ongoing GWAS discovery study. Using the ranked P-values of the breast cancer associations with the imputed genotype of 1.4 M SNPs, 19,029 SNPs were selected and designed for inclusion on a custom Illumina array that included a total of 211,155 SNPs as part of a multi-consortial project. DNA samples from 3,881 breast cancer affected and 4,330 unaffected BRCA2 mutation carriers from 47 studies belonging to the Consortium of Investigators of Modifiers of BRCA1/2 were genotyped and available for analysis. We replicated previously reported breast cancer susceptibility alleles in these BRCA2 mutation carriers and for several regions (including FGFR2, MAP3K1, CDKN2A/B, and PTHLH) identified SNPs that have stronger evidence of association than those previously published. We also identified a novel susceptibility allele at 6p24 that was inversely associated with risk in BRCA2 mutation carriers (rs9348512; per allele HR = 0.85, 95% CI 0.80-0.90, P = 3.9×10−8). This SNP was not associated with breast cancer risk either in the general population or in BRCA1 mutation carriers. The locus lies within a region containing TFAP2A, which encodes a transcriptional activation protein that interacts with several tumor suppressor genes. This report identifies the first breast cancer risk locus specific to a BRCA2 mutation background. This comprehensive update of novel and previously reported breast cancer susceptibility loci contributes to the establishment of a panel of SNPs that modify breast cancer risk in BRCA2 mutation carriers. This panel may have clinical utility for women with BRCA2 mutations weighing options for medical prevention of breast cancer

    OBJECTIVES: To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic germline mutation in the BRCA1 or BRCA2 genes. PARTICPANTS AND METHODS: Men enrolled in the IMPACT study were invited to complete a questionnaire at collaborating sites prior to each annual screening visit. The questionnaire included sociodemographic characteristics and the following measures: the Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), 36-item short-form health survey (SF-36), Memorial Anxiety Scale for Prostate Cancer, Cancer Worry Scale-Revised, risk perception and knowledge. The results of the baseline questionnaire are presented. RESULTS: A total of 432 men completed questionnaires: 98 and 160 had mutations in BRCA1 and BRCA2 genes, respectively, and 174 were controls (familial mutation negative). Participants' perception of PCa risk was influenced by genetic status. Knowledge levels were high and unrelated to genetic status. Mean scores for the HADS and SF-36 were within reported general population norms and mean IES scores were within normal range. IES mean intrusion and avoidance scores were significantly higher in BRCA1/BRCA2 carriers than in controls and were higher in men with increased PCa risk perception. At the multivariate level, risk perception contributed more significantly to variance in IES scores than genetic status. CONCLUSION: This is the first study to report the psychosocial profile of men with BRCA1/BRCA2 mutations undergoing PCa screening. No clinically concerning levels of general or cancer-specific distress or poor quality of life were detected in the cohort as a whole. A small subset of participants reported higher levels of distress, suggesting the need for healthcare professionals offering PCa screening to identify these risk factors and offer additional information and support to men seeking PCa screening

    Abstract.-Present study was conducted to investigate the prevalence of hepatitis B and C viruses (HBV, HCV) among the general population of a village population in the Azad Jammu and Kashmir area in Pakistan. Randomly selected male and female individuals of 5 to 70 years of age were screened for anti-body test for HCV and HBV. The samples found positive for virus related antigen and antibody were further investigated for the presence of viral RNA and DNA in the plasma using polymerase chain reaction (PCR). HCV positive samples were further analyzed for the genotypes. Total 520 individuals (250 males and 270 females) from general population who willingly participated in the screening process were included in the study. Prevalence and the type of virus, the age, sex, history of exposure and the previous surgical of the participants was also investigated. 7.5% of participants were found positive against HCV antibody and only 0.96% were positive for HBV surface antigen. Among the individuals positive for HCV-PCR, the genotype 3a was the most prevalent, whereas genotypes 2a, 1b, 3b and an unidentified strain were also found. It is concluded that PCR based analysis along with concomitant HBsAg and anti-HCV testing permits diagnosis HBV and HCV infections

    Henkilöstön vaihtuvuus ja siihen liittyvÀt tekijÀt telemarkkinointialalla : case: Gainer Oy

    TĂ€mĂ€ opinnĂ€ytetyö toteutettiin toimeksiantosopimuksena Gainer Oy:lle, joka on toiminut telemarkkinoinnin alalla jo vuodesta 1984. OpinnĂ€ytetyön tutkimusstrategiaksi valittiin case study eli tapaustutkimus. KĂ€ytimme tutkimusmenetelmĂ€nĂ€ kvalitatiivista eli laadullista tutkimusta. Tavoitteenamme oli tutkia ja selvittÀÀ henkilöstön vaihtuvuutta ja siihen liittyviĂ€ tekijöitĂ€ alalla, jossa henkilöstön vaihtuvuus koetaan ongelmaksi. Teoriaosuudessa kĂ€sittelemme teoreettisen viitekehyksen liittyen työnantajan keinoihin vaikuttaa työntekijĂ€n sitouttamiseen. TĂ€mĂ€ on jaettu kahteen osa-alueeseen, jotka ovat rekrytointi sekĂ€ työhyvinvointi ja osaamisen kehittĂ€minen. EmpiirisessĂ€ osiossa pÀÀdyimme kĂ€yttĂ€mÀÀn puolistrukturoitua teemahaastattelua, joka toteutettiin suurimmaksi osaksi puhelimitse sekĂ€ muutama haastattelu tehtiin kasvotusten. Teemahaastattelu valikoitui parhaimmaksi menetelmĂ€ksi johtuen aiheen moniulotteisuudesta. Avoimella haastattelulla emme olisi vĂ€lttĂ€mĂ€ttĂ€ saaneet merkittĂ€vÀÀ tietoa samassa mittakaavassa kuin puolistrukturoidulla mallilla. OpinnĂ€ytetyön tuloksena pÀÀdyimme esittĂ€mÀÀn toimeksiantajalle muutamia kehitysehdotuksia. Haastatteluista johdetuilla pÀÀtelmillĂ€ saatettaisiin parantaa rekrytoinnin onnistumista, joka osaltaan parantaa kannattavuutta niin tuloksellisesti, kuin henkilöstön resurssejakin sÀÀstĂ€en. Kehitysehdotuksia muodostui myös muihin osa-alueisiin liittyen. NĂ€illĂ€ on myös vaikutusta henkilöstön yleiseen työhyvinvointiin ja työssĂ€ jaksamiseen.This thesis was carried out as a commission agreement for Gainer Oy, which has operated in the field of telemarketing since 1984. Our study was carried out as a case study using qualitative approach as our research method. Our objective was to study personnel turnover and matters relating to it in a field where personnel turnover is seen as a problem. In the theoretical section of the study we deal with the theoretical frame of reference related to the employer's means to influence employee engagement. This is divided into two sections that are recruiting, and occupational health and development of skills. In the empirical part of our study, we ended up using half-structured theme interviews, which were mainly carried out by telephone. A few interviews were carried out face-to-face. Theme interview was selected to be the best method because of the multidimensionality of the subject. By using open interviews, we would not necessarily have received as much significant information as by using the half-structured model. As a result of our study, we presented a few development proposals for our client/commissioner. The conclusions drawn from the interviews may lead to more successful recruiting, which in turn improves viability both in terms of productivity and by saving the resources of the personnel. There were also other development proposals concerning other areas. The results of the study may also help to improve the general well-being at work and coping with one’s workload
