RESUMO

BACKGROUND: No information is available on the attitudes of General Practitioners (GPs) and Breast Surgeons (BSs) to their delivery of genetic, environmental and lifestyle risk factor information about breast cancer. The aim of this study was to describe the Breast Cancer Risk Communication Behaviours (RCBs) reported by GPs and BSs in four European countries and to determine the relationships between their RCBs and their socio-occupational characteristics. METHODS: Self-administered questionnaires assessing breast cancer risk communication behaviours using vignettes were mailed to a sample of Breast Surgeons (BS) and General Practitioners (GP) working in France, Germany, the Netherlands, and the UK (N = 7292). Their responses to questions about the risk factors were first ordered and compared by specialty and country after making multivariate adjustments. Rather than defining a standard Risk Presentation Format (RPF) a priori, the various RPFs used by the respondents were analyzed using cluster analysis. RESULTS: Family history and hormonal replacement therapy were the risk factors most frequently mentioned by the 2094 respondents included in this study. Lifestyle BC risk factors such as obesity and alcohol were rarely/occasionally mentioned, but this point differed (p < 0.001) depending on the country and the specialty of the providers involved. Five distinct RPF profiles including the numerical/verbal presentation of absolute/relative risks were identified. The most frequently encountered RPF (34.2%) was characterized by the fact that it included no negative framing of the risks, i.e., the probability of not developing cancer was not mentioned. Age, specialty and country of practice were all found to be significant determinants of the RPF clusters. CONCLUSIONS: The increasing trend for GPs and BSs to discuss lifestyle risk factors with their patients suggests that this may be a relevant means of improving breast cancer prevention. Physicians' risk communication skills should be improved during their initial and vocational training.

RESUMO

Marfan syndrome (MFS) is caused by mutations in the fibrillin-1 (FBN1) gene, and mutations in FBN1 are known to be responsible for over 90% of all MFS cases. Locus heterogeneity has also been reported and confirmed, with mutations in the receptor genes TGFBR1 and TGFBR2 identified in association with MFS-related phenotypes. It is now known that dysregulation of TGF-ß signaling is involved in MFS pathogenesis. To test the hypothesis that dysregulation of TGFBR3-associated TGF-ß signaling is implicated in MFS or related phenotype pathogenesis, we selected a cohort of 49 patients, fulfilling or nearly fulfilling the diagnostic criteria for MFS. The patients were known not to carry a mutation in the FBN1 gene (including three 5' upstream alternatively spliced exons), the TGFBR1 and TGFBR2 genes. Mutation screening for the TGFBR3 gene in these patients and in controls led to the identification of a total of ten exonic (one novel), four intronic (one novel) and one 3'UTR variant in the TGFBR3 gene. Our data suggest that variations in TGFBR3 gene appear not to be associated with MFS or related phenotype.

RESUMO

Werner syndrome (WS) is an autosomal recessive segmental progeroid syndrome caused by null mutations at the WRN locus, which codes for a member of the RecQ family of DNA helicases. Since 1988, the International Registry of Werner syndrome had enrolled 130 molecularly confirmed WS cases from among 110 worldwide pedigrees. We now report 18 new mutations, including two genomic rearrangements, a deep intronic mutation resulting in a novel exon, a splice consensus mutation leading to utilization of the nearby splice site, and two rare missense mutations. We also review evidence for founder mutations among various ethnic/geographic groups. Founder WRN mutations had been previously reported in Japan and Northern Sardinia. Our Registry now suggests characteristic mutations originated in Morocco, Turkey, The Netherlands and elsewhere.

RESUMO

Age-related macular degeneration (AMD) is a clinically heterogeneous disease and constitutes the major cause of visual impairment in the elderly population worldwide. Rhesus macaques also possess a macula and, like humans, develop drusen-associated, age-related macular pathologies. Susceptibility to AMD in humans and drusen formation in rhesus macaques both have been shown to be associated with variation in the HTRA1 and ARMS2 genes. To corroborate these results we genotyped a cohort of 116 rhesus macaques with and without macular drusen. Like in humans, markers in the two genes showed a significant association with drusen formation at the genotype level. Joint haplotype analysis revealed, however, that the disease association observed in rhesus macaques was entirely attributable to a promoter polymorphism (-558G>T) of the HTRA1 gene.

RESUMO

Fibrillin-1 is a multifunctional extracellular protein encoded by the FBN1 gene. FBN1 is 237 kb in size and is located on chromosome 15q21. FBN1 mutations are known to cause Marfan syndrome and other fibrillinopathies. FBN1 is composed of 65 exons and 3 additional alternatively spliced exons at the 5' end. The absence of the peptide sequence from the extreme N-terminus of the fibrillin-1 protein and the presence of in-frame and alternatively spliced exons at the 5' end of the FBN1 gene create some ambiguity about the translation start site and indicate a functional role of these alternatively spliced exons. We demonstrate here the conservation of 5'-upstream region of the FBN1 gene among humans and non-human primates.

RESUMO

PURPOSE: To assess how general practitioners (GPs) from European countries prioritized their genetic educational needs according to their geographic, sociodemographic, and educational characteristics. METHODS: Cross-sectional survey, random and total samples of GPs in five European countries (France, Germany, the Netherlands, Sweden, and United Kingdom), mailed questionnaires; OUTCOME: Genetic Educational Priority Scale (30 items; six subscores). RESULTS: A total 1168 GPs answered. Priorities differed (P < 0.001) but were consistently ranked across the countries. Previous education had a marginal effect on priorities. Women gave higher priorities than men to Genetics of Common Disorders (adjusted odds ratio [OR adj], 2.5; 95% confidence interval [CI], 1.6-3.8), Psychosocial and Counseling Issues (OR adj, 1.6; 95% CI, 1.1-2.5), and Ethical, Legal, and Public Health Issues (OR adj, 1.3; 95% CI, 1.1-1.8), but lower than men to Techniques and Innovation in Genetics (OR adj, 0.7; 95% CI, 0.5-0.9). Older physicians gave higher priorities to Basic Genetics and Congenital Malformations (OR adj, 1.5; 95% CI, 1.1-1.9), and to Techniques and Innovation in Genetics (OR adj: 1.3; 95% CI, 1.0-1.7), compared with their younger colleagues. CONCLUSIONS: Expressed genetic educational needs vary according to the countries and sociodemographics. In accordance, training could be more focused on genetics of common disorders and on how to approach genetic risk in clinical practice rather than on ethics, new technologies, or basic concepts.

RESUMO

OBJECTIVE: To develop a generic scale for assessing attitudes towards genetic testing and to psychometrically assess these attitudes in the context of BRCA1/2 among a sample of French general practitioners, breast specialists and gyneco-obstetricians. STUDY DESIGN AND SETTING: Nested within the questionnaire developed for the European InCRisC (International Cancer Risk Communication Study) project were 14 items assessing expected benefits (8 items) and drawbacks (6 items) of the process of breast/ovarian genetic cancer testing (BRCA1/2). Another item assessed agreement with the statement that, overall, the expected health benefits of BRCA1/2 testing exceeded its drawbacks, thereby justifying its prescription. The questionnaire was mailed to a sample of 1,852 French doctors. Of these, 182 breast specialists, 275 general practitioners and 294 gyneco-obstetricians completed and returned the questionnaire to the research team. Principal Component Analysis, Cronbach's α coefficient, and Pearson's correlation coefficients were used in the statistical analyses of collected data. RESULTS: Three dimensions emerged from the respondents' responses, and were classified under the headings: "Anxiety, Conflict and Discrimination", "Risk Information", and "Prevention and Surveillance". Cronbach's α coefficient for the 3 dimensions was 0.79, 0.76 and 0.62, respectively, and each dimension exhibited strong correlation with the overall indicator of agreement (criterion validity). CONCLUSIONS: The validation process of the 15 items regarding BRCA1/2 testing revealed satisfactory psychometric properties for the creation of a new scale entitled the Attitudes Towards Genetic Testing for BRCA1/2 (ATGT-BRCA1/2) Scale. Further testing is required to confirm the validity of this tool which could be used generically in other genetic contexts.

RESUMO

Allogeneic stem cell transplantation (allo-HSCT) is one of the curative treatments for hematologic malignancies, but is hampered by severe complications, such as acute or chronic graft-versus-host-disease (aGvHD; cGvHD) and infections. CD34-selection of stem cells reduces the risk of aGvHD, but also leads to increased infectious complications and relapse. Thus, we studied the safety, efficacy, and feasibility of transfer of gene modified donor T-cells shortly after allo-HSCT in two clinical trials between 2002 and 2007 and here we compare the results to unmodified donor leukocyte infusion (DLI). The aim of these trials was to provide patients with the protection of T-cells after T-cell-depleted allo-HSCT in the matched or mismatched donor setting with an option to delete transduced T-cells, if severe aGvHD occurred within the trial period. Donor-T-cells were transduced with the replication-deficient retrovirus SFCMM-3, expressing HSV-TK and the truncated ΔLNGFR for selection of transduced cells. Transduced cells were transfused either after day +60 (matched donors) or on day +42 (haploidentical donors). Nine patients were included in the first trial (MHH; 2002 until 2007), two were included in TK007 (2005-2009) and six serves as a control group for outcome after haploidentical transplantation without HSV-TK-transduced DLI. Three patients developed acute GvHD, two had grade I of the skin, one had aGvHD on day +131 (post-HSCT; +89 post-HSV-TK DLI) grade II, which was successfully controlled by ganciclovir (GCV). Donor chimerism was stabilized after transfusion of the transduced cells in all patients treated. Functionality of HSV-TK gene expressing T-cells was shown by loss of bcr-able gene expression as well as by control of cytomegalovirus-reactivation. To date, six patients have relapsed and died, two after a second hematopoietic stem cell transplantation without T-cell depletion or administration of unmodified T-cells. Eleven patients (seven post-HSV-TK DLI) are alive and well to date.

RESUMO

In Germany, many highly specialized facilities for the diagnosis and treatment of rare diseases exist. However it is quite difficult for patients to find the required specialists because of the fact that information on the internet is scattered and of variable quality. The German Federal Ministry of Health initiated several activities to address this issue. This paper describes the project se-atlas which aims at presenting the medical care options for people with rare diseases on an interactive map and in a list format. Potential users of this resource will be patients and their relatives, doctors, non-medical personnel and the general public. Most information derived from the data sets is already listed in ORPHANET. The project's primary goals are to steadily increase the data set and to ensure its quality. This paper presents the goals and measures taken in this project. It gives an overview of the challenges implementing such a new service and the visions behind.

RESUMO

Seven patients with acute myeloid leukemia (AML) and two patients with chronic myelogenous leukemia (CML) were transplanted from HLA-identical sibling donors with CD34(+) cell-enriched stem cells (HSCTs) without further immunosuppression. The myeloablative standard transplantation protocol was adapted to include transfusion of gene-modified donor T cells after HSCT. Donor T cells were transduced with the replication-deficient retrovirus SFCMM-3, which expresses herpes simplex thymidine kinase (HSV-Tk) and a truncated version of low-affinity nerve growth factor receptor (ΔLNGFR) for selection and characterization of transduced cells. Transduced T cells were detectable in all patients during follow-up for up to 5 years after transfusion. Proteomic screening for development of acute graft-versus-host disease (aGvHD) was applied to five of the seven patients with AML. No positivity for the aGvHD grade II-specific proteomic pattern was observed. Only one patient developed aGvHD grade I. To date, three of the patients with AML relapsed; one responded to three escalating transfusions of lymphocytes from the original donor and is in complete remission. Two were retransplanted with non-T cell-depleted peripheral blood stem cells from their original donors and died after retransplantation of septic complications or relapse, respectively. In one patient with CML, loss of bcr-abl gene expression was observed after an expansion of transduced cells. Seven of nine patients are alive and in complete remission.

RESUMO

It is increasingly recognised that genetics will have to be integrated into all parts of primary health care. Previous research has demonstrated that involvement and confidence in genetics varies amongst primary care providers. We aimed to analyse perceptions of primary care providers regarding responsibility for genetic tasks and factors affecting those perceptions. Postal questionnaire including a hypothetical case management scenario of a cardiac condition with a genetic component was sent to random samples of medically qualified general practitioners in France, Germany, Netherlands, Sweden and UK (n = 1,168). Logistic regression analysis of factors affecting primary care practitioners' willingness to carry out genetic tasks themselves was conducted; 61% would take a family history themselves but only 38% would explain an inheritance pattern and 16% would order a genetic test. In multivariate analysis, only the country of practice was consistently predictive of willingness to carry out genetic tasks, although male gender predicted willingness to carry out the majority of tasks studied. The stage of career at which education in genetics had been provided was not predictive of willingness to carry out any of the tasks analysed. Country of practice is significantly predictive of attitudes towards genetics in primary care practice and therefore genetic education structure and content in Europe will need to be significantly tailored towards country-specific approaches.

RESUMO

OBJECTIVE: to investigate whether practising midwives are adequately prepared to integrate genetic information into their practice. DESIGN: a cross-sectional, postal, structured questionnaire survey was sent to practising midwives. SETTING: practising midwives from the Netherlands (NL), Sweden (SE) and the United Kingdom (UK). PARTICIPANTS: 1021 replies were received, achieving a response rate of 62%. FINDINGS: 79% (799/1015) of midwives reported attending courses with some 'genetic content' during their initial training. Sixty-eight per cent (533/784) judged this to have been useful for clinical practice. Variation was seen between countries in the amount of genetic content in post-registration training (SE 87%, NL 44%, UK 17%) and most was considered useful. Questions assessing clinical activity identified a current need for genetic knowledge. Midwives described low levels of self-reported confidence both in overtly genetic procedures and in everyday tasks that were underpinned by genetic knowledge. For eight of the 12 procedures, fewer than 20% of midwives considered themselves to be confident. Differences were apparent between countries. Midwives identified psychosocial, screening and risk assessment aspects of genetic education as being important to them, rather than technical aspects or genetic science. CONCLUSIONS: given the low reported confidence with genetic issues in clinical practice, it is essential that this is addressed in terms of the amount, content and targeting of genetic education. This is especially important to ensure the success of national antenatal and baby screening programmes. The results of this study suggest that midwives would welcome further training in genetics, addressing genetic topics most relevant to their clinical practice.
