Abstract: BACKGROUND: Nowadays there is a debate about the indication of the oral whole-cell/recombinant B-subunit cholera vaccine (WC/rBS) in traveller's diarrhoea. However, a cost-benefit analysis based on real data has not been published. METHODS: A cost-effectiveness and cost-benefit study of the oral cholera vaccine (WC/rBS), Dukoral for the prevention of traveller's diarrhoea (TD) was performed in subjects travelling to cholera risk areas. The effectiveness of WC/rBS vaccine in the prevention of TD was analyzed in 362 travellers attending two International Vaccination Centres in Spain between May and September 2005. RESULTS: The overall vaccine efficacy against TD was 42,6%. Direct healthcare-related costs as well as indirect costs (lost vacation days) subsequent to the disease were considered. Preventive vaccination against TD resulted in a mean saving of 79.26 euro per traveller. CONCLUSION: According to the cost-benefit analysis performed, the recommendation for WC/rBS vaccination in subjects travelling to zones at risk of TD is beneficial for the traveller, regardless of trip duration and visited continent.
Abstract: Spain is frequently the entrance country into the European Union for undocumented immigrants, especially those from the Magreb (Northern Africa). Forensic age estimates for these persons are difficult because systematic studies of dental maturity are lacking. Three different populations were analyzed to determine the pattern of development of third molars as a tool for age estimation in people of different ethnic and geographic origin. Orthopantomograms from two different populations of Spanish origin (Galicia in northwestern continental Spain, and Ceuta, a Spanish province in Northern Africa) were compared to radiographs of molars from a Magrebian population (Northern Africa) resident in Ceuta. Orthopantomograms were obtained from a private dental clinic (n=344) in Galicia and from the Public Oral Health Services (n=228) in Ceuta. We looked for differences in third molar mineralization (determined with the Demirjian scale) that might serve as age indicators (older versus younger than 18 years). Differences in maturation patterns were found between sexes and populations of origin. Mineralization of tooth 38 was more advanced in males than females among subjects 18 years of age and older in all three populations. Moreover, mineralization of tooth 38 in subjects aged 18 years and older was significantly slower in the Spanish-Galicia population than in the Magrebian-Ceuta population. We found no significant differences between Magrebian and Spanish individuals from Ceuta. We conclude that differences in tooth 38 mineralization may be related more with socio-geographical than ethnic origin (ancestry), and thus constitute evidence of the relevance of socio-geographic rather than genetic factors in third molar development. We used ROC analysis to determine the accuracy of the examiner's ability to correctly estimate age as younger or older than 18 years. The results suggest that Demirjian stage for tooth 38 can be considered a good indicator of age in all three populations.
Abstract: Information and Communication Technologies (ICTs) are revolutionizing how healthcare systems deliver top-quality care to citizens. In this way, Open Source Software (OSS) has demonstrated to be an important strategy to spread ICTs use. Several human and technological barriers in adopting OSS for healthcare have been identified. Human barriers include user acceptance, limited support, technical skillfulness, awareness, resistance to change, etc., while Technological barriers embrace need for open standards, heterogeneous OSS developed without normalization and metrics, lack of initiatives to evaluate existing health OSS and need for quality control and functional validation. The goals of PESCA project are to create a platform of interoperable modules to evaluate, classify and validate good practices in health OSS. Furthermore, a normalization platform will provide interoperable solutions in the fields of healthcare services, health surveillance, health literature, and health education, knowledge and research. Within the platform, the first goal to achieve is the setup of the collaborative work infrastructure. The platform is being organized as a Social Network which works to evaluate five scopes of every existing open source tools for eHealth: Open Source Software, Quality, Pedagogical, Security and privacy and Internationalization/I18N. In the meantime, the knowledge collected from the networking will configure a Good Practice Repository on eHealth promoting the effective use of ICT on behalf of the citizen's health.
Abstract: OBJECTIVE: To investigate the effectiveness of an oral cholera vaccine (Dukoral((R))) in preventing travellers' diarrhoea. MATERIAL AND METHODS: A retrospective study was conducted among travellers who had attended the International Vaccination Centre in Malaga, Spain, before starting their journey. A telephone interview was undertaken from November 2005 to January 2006 after the travellers had returned from their trip. The relationship between vaccination with Dukoral((R)) and travellers' diarrhoea was analysed by means of a logistic regression model, adjusting for possible confounding variables (traveller's age, duration of trip and region visited). RESULTS: The overall incidence of diarrhoea in vaccinated travellers was 23% compared with 40% in non-vaccinated travellers (historical control group) (p=0.004). Short episodes of diarrhoea were reported in significantly more travellers of the vaccinated group than of the non-vaccinated group (average duration of diarrhoea 2.21 days versus 3.97 days, p=0.005). The incidence of diarrhoea was significantly lower among vaccinated than non-vaccinated travellers who went to Africa for less than 3 weeks (16% versus 48%, p=0.002) or India and South East Asia (19% versus 50%, p =0.052) for more than 3 weeks. No adverse events were reported in the group of vaccinated travellers. DISCUSSION: Vaccination reduced the risk of travellers' diarrhoea by 43%; possibly due to the protective effect of the oral vaccine Dukoral((R)) against travellers' diarrhoea caused by enterotoxigenic Escherichia coli (ETEC) or cholera. The efficacy of vaccination increased after adjusting for confounding factors, being modified by traveller age (under 30 years, or 45 years and older the protective effect of the vaccine is 4.8 greater, 95% confidence interval (CI): 2.1-10.7). The number needed to treat to prevent one traveller from suffering from one or more episodes of travellers' diarrhoea was 5.8.
