      Mollenhauer, B; Zerr, I; Ruge, D; Krause, Gerard; Mehnert, W H; Kretzschmar, H A; Poser, S; Helmholtz Centre for infection research, Inhoffenstr. 7, D-38124 Braunschweig, Germany. (2002-02-15)
      Analogous to prospective studies in other countries, prevalance and symptoms of sporadic Creutzfeldt-Jakob disease (CJD) were recorded in order to assess irregularities in the incidence of the disease in Germany since the onset of bovine spongioform encephalopathy (BSE).
    • Evaluation of a questionnaire to assess selected infectious diseases and their risk factors : findings of a multicenter study.

      The risk to die from an infectious disease in Germany has been continuously decreasing over the last century. Since infections are, however, not only causes of death but risk factors for diseases like cardiovascular diseases, it is essential to monitor and analyze their prevalence and frequency, especially in consideration of the increased life expectancy. To gain more knowledge about infectious diseases as risk factors and their implications on the condition and change of the immune status, the German National Cohort (GNC), a population-based prospective cohort study, will recruit 200,000 subjects between 2014 and 2017. In Pretest 1, a feasibility study for the GNC, we evaluated a self-administered and self-report questionnaire on infectious diseases and on the use of health care facilities (hereinafter called "ID Screen") for feasibility and validity.
    • The German National Cohort: aims, study design and organization.

      The German National Cohort (GNC) is a joint interdisciplinary endeavour of scientists from the Helmholtz and the Leibniz Association, universities, and other research institutes. Its aim is to investigate the causes for the development of major chronic diseases, i.e. cardiovascular diseases, cancer, diabetes, neurodegenerative/-psychiatric diseases, musculoskeletal diseases, respiratory and infectious diseases, and their pre-clinical stages or functional health impairments. Across Germany, a random sample of the general population will be drawn by 18 regional study centres, including a total of 100,000 women and 100,000 men aged 20-69 years. The baseline assessments include an extensive interview and self-completion questionnaires, a wide range of medical examinations and the collection of various biomaterials. In a random subgroup of 20 % of the participants (n = 40,000) an intensified examination ("Level 2") programme will be performed. In addition, in five of the 18 study centres a total of 30,000 study participants will take part in a magnetic resonance imaging examination programme, and all of these participants will also be offered the intensified Level 2 examinations. After 4-5 years, all participants will be invited for a re-assessment. Information about chronic disease endpoints will be collected through a combination of active follow-up (including questionnaires every 2-3 years) and record linkages. The GNC is planned for an overall duration of 25-30 years. It will provide a major, central resource for population-based epidemiology in Germany, and will help to identify new and tailored strategies for early detection, prediction, and primary prevention of major diseases.
    • High level of gastrointestinal nosocomial infections in the german surveillance system, 2002-2008.

      Spackova, Michaela; Altmann, Doris; Eckmanns, Tim; Koch, Judith; Krause, Gerard; Helmholtz Centre for infection research, Inhoffenstr. 7, D-38124 Braunschweig, Germany. (2010-12)
      Surveillance of nosocomial infections (NIs) is well established in many countries but often does not include gastrointestinal infections. We sought to determine the proportion of NIs among all hospitalized cases for the 4 most prevalent types of gastrointestinal infections in Germany.
    • ["I cannot kiss my wife"- An Analysis of Daily Experiences of MRSA-carriers].

      Raupach-Rosin, H; Klett-Tammen, C J; Schmalz, O; Karch, A; Castell, S; Mikolajczyk, Rafael T; Helmholtz-Zentrum für Infektionsforschung GmbH, Inhoffenstr. 7, 38124 Braunschweig, Germany. (2016-12)
      Objectives: There are no data available on the quality of care after discharge from hospital and only limited data are available on the psychosocial effects of being an MRSA carrier within the German health system.Methods:Patients who tested positive for MRSA in the previous year were invited to take part in focus groups.Results:2 focus groups with a total of 9 MRSA-carriers were conducted. The level of knowledge about MRSA differed between participants. In some cases, lack of information led to uncertainty and inappropriate measures to counteract MRSA. Some participants restricted their social contacts, especially to children, in order to prevent transmission. Patients experienced stigmatization in the health care system more often in inpatient care than in the outpatient sector. Only in a few cases both eradication therapy and swabs for control purposes were carried out.Conclusions:Information about the appropriate treatment and management of MRSA should be made available to patients more easily; in particular, patients need to be informed that MRSA is no threat to healthy individuals. Despite the desire of MRSA-carriers to become MRSA negative, treatment and control of MRSA seem to have low priority in the ambulant health care sector in Germany.
    • Serial home-based self-collection of anterior nasal swabs to detect Staphylococcus aureus carriage in a randomized population-based study in Germany.

      Akmatov, Manas K; Mehraj, Jaishri; Gatzemeier, Anja; Strömpl, Julia; Witte, Wolfgang; Krause, Gerard; Pessler, Frank; Helmholtz Centre for infection research, Inhoffenstr. 7, D-38124 Braunschweig, Germany. (2014-08)
      Participant-collected serial nasal swabs would be a cost-efficient feature of prospective population-based microbiological studies. We examined the feasibility of serial anterior nasal self-swabbing for Staphylococcus aureus detection in a prospective population-based study in Braunschweig, Germany, and assessed the impact of three interventions on participation and compliance.
