Abstract
Prospective surveillance of Creutzfeldt–Jakob disease (CJD) was initiated in Denmark in 1997, following the observation of variant CJD in the United Kingdom. Demographic, clinical and diagnostic information was collected for each patient with clinical suspicion of CJD. Here we describe the methods for surveillance and the observed outcomes between 1 January 1997 and 31 December 2008. A total of 83 patients were classified as sporadic CJD, 47 were definite diagnoses, 34 probable and two possible. This resulted in a mean incidence of 1.26 patients with probable and definite sporadic CJD per million inhabitants. Two sporadic CJD patients were found to have a genetic variant of unknown significance: Thr201Ser and Glu200Asp. One patient was diagnosed with Gerstmann-Sträussler-Scheinker syndrome. No patients were classified as having variant, iatrogenic or familial CJD. The Danish surveillance system, like those in other countries, has a multidisciplinary approach, which is labour-intensive and time-consuming but ensures the most complete set of information possible. With this approach we think that patients with variant CJD would have been detected had they occurred in Denmark. Certain aspects of CJD surveillance need further discussion at European level and beyond, in order to find a balance between efficiency of the systems and accuracy of surveillance data.

Abstract
The nature and time evolution of the primary excitations in the pristine conjugated polymer, PCDTBT, are investigated by femtosecond-resolved fluorescence up-conversion spectroscopy. The extensive study includes data from PCDTBT thin film and from PCDTBT in chlorobenzene solution, compares the fluorescence dynamics for several excitation and emission wavelengths, and is complemented by polarization-sensitive measurements. The results are consistent with the photogeneration of mobile electrons and holes by interband π-π* transitions, which then self-localize within about 100 fs and evolve to a bound singlet exciton state in less than 1 ps. The excitons subsequently undergo successive migrations to lower energy localized states, which exist as a result of disorder. In parallel, there is also slow conformational relaxation of the polymer backbone. While the initial self-localization occurs faster than the time resolution of our experiment, the exciton formation, exciton migration, and conformational changes lead to a progressive relaxation of the inhomogeneously broadened emission spectrum with time constants ranging from about 500 fs to tens of picoseconds. The time scales found here for the relaxation processes in pristine PCDTBT are compared to the time scale (<0.2 ps) previously reported for photoinduced charge transfer in phase-separated PCDTBT:fullerene blends (Phys. Rev. B 2010, 81, 125210). We point out that exciton formation and migration in PCDTBT occur at times much longer than the ultrafast photoinduced electron transfer time in PCDTBT:fullerene blends. This disparity in time scales is not consistent with the commonly proposed idea that photoinduced charge separation occurs after diffusion of the polymer exciton to a fullerene interface. We therefore discuss alternative mechanisms that are consistent with ultrafast charge separation before localization of the primary excitation to form a bound exciton.

Abstract
Denmark is currently experiencing an outbreak of syphilis that began in 2003 and has continued in 2004. Data from the national surveillance system show that most cases are in men who have sex with men (MSM), and that a large proportion of these patients are also HIV positive. The proportion of known HIV positive cases in MSM notified with syphilis during the outbreak has, however, not been significantly different from previous years. The majority of cases were reported from Copenhagen municipality, and 70% of the cases were acquired domestically. The outbreak does not seem to be affecting the age group under 20 years. We speculate that most of the MSM found with both syphilis and HIV were already HIV positive when they acquired syphilis infection.

Abstract
Background The prone sleeping position for sleeping has been identified as the principal risk factor for sudden infant death syndrome (SIDS).ObjectiveThe aim of this study was to determine the prevalence of different sleeping positions and other risk factors for SIDS and to identify the advice given to parents in several maternity units in Latin America and the Caribbean through a specially-designed questionnaire.MethodsDescriptive cross-sectional study based in hospitals. All the countries in Latin America and the Caribbean were contacted through the Pan American Health Organization and responses were obtained from 16 countries.ResultsTwo hundred thirteen hospitals answered the survey. The preferred sleeping position for healthy infants was prone in 8.5 % of the hospitals, side in 48.8 %, and supine in 25.2 %. In 17.5 % of the hospitals no position was preferred or the answers were inconsistent.Concerning the recommendations given to parents on the best position for their infants at home, 25.7 % recommended the supine position, 7.6 % the prone position, 59.0 % the side position while 7.6 % made no recommendations.ConclusionsThe results of this study show that in the hospitals surveyed there is a policy of not placing healthy neonates in the prone position. However, the most frequent position was the side, which is not advisable as it increases the risk of SIDS. To reduce in the incidence of SIDS, campaigns to increase the use of the supine position should be carried out in hospitals and among the general public.

Abstract
BACKGROUND The incidence of self-poisoning is on the increase. Most patients who self-poison are dealt with initially in the general hospital. Therefore, the type and quality of care self-poisoning patients receive will depend, in part, on how they are viewed by nursing staff within the general hospital setting. A knowledge and understanding of the attitudes held by nurses towards self-poisoning patients is therefore important to those involved in the planning and delivery of care towards this client group. Previous studies have examined health care professionals' attitudes towards people who self-poison. Usually, however, these have not focused specifically on nurses' attitudes, and they have ignored the relationship between the attitudes expressed by staff and their intentions to engage in subsequent caring behaviour of one sort or another. It is hence unclear how the findings of such studies are relevant or applicable to nursing policy and practice. AIMS The present study aims to address these limitations using a methodology informed by the theory of reasoned action. The study aims to separate out the distinctive roles played by nurses' own attitudes, and the social pressures represented by other people's attitudes, in determining the types of caring behaviour in which nurses intend to engage when dealing with self-poisoning patients. DESIGN/METHODS The study adopts a questionnaire-based approach incorporating two specially designed vignettes. RESULTS The results show that nurses' own attitudes, and what they believe about the attitudes of others, predict their behavioural intentions towards self-poisoning patients. The study also shows that nurses with a more positive orientation towards self-poisoning patients differ in behavioural and normative beliefs from nurses who have a less positive orientation. CONCLUSIONS The implications for future attempts to explore the relationship between nurses' attitudes and subsequent caring behaviour are considered, along with implications for nursing policy and practice.
