A Bayesian Discrepancy Test (BDT) is proposed to evaluate the distance of a given hypothesis with respect to the available information (prior law and data). The proposed measure of evidence has properties of consistency and invariance. After having presented the similarities and differences between the BDT and other Bayesian tests, we proceed with the analysis of some multiparametric case studies, showing the properties of the BDT. Among them conceptual and interpretative simplicity, possibility of dealing with complex case studies.
The use of testing procedures for comparing two coefficients of variation (CVs) of independent populations is not extensively explored in the Bayesian context. We propose to address this issue through a test based on a measure of evidence, the Bayesian Discrepancy Measure, recently introduced in the literature. Computing the Bayesian Discrepancy Measure is straightforward when the CVs depend on a single parameter of the distribution. In contrast, it becomes more difficult when this simplification does not occur since more parameters are involved, requiring often the use of MCMC methods. We derive the Bayesian Discrepancy Measure and the related test by considering a variety of distribution assumptions with multiparametric CVs and apply them to real datasets. As far as we know, some of the examined problems have not yet been covered in the literature.
Lymphedema of lower limbs represents an important health problem, characterized by the necessity to identify new methods of treatment. The aim of this study was to evaluate the efficacy of the treatment with Lymphatic Kinesiology Taping (LKT) or Intermittent Pneumatic Compression therapy (IPC) on a homogeneous group of 40 women affected by primary lymphedema within stage 2 of lower limbs, comparing the two methods. Patients were equally and randomly divided into a group A subjected to application of LKT and group B subjected to IPC. All patients were evaluated through electric bioimpedentiometry (analysis of Total Body Water and Extracellular Water) and circumferential measurement of lower limbs through a measurement tape, both before and after the protocol (T0 and T1). Both treatment groups highlighted an improvement of the lymphedema, with a marked reduction of volume of lower limbs and a better hydric balance of the body. LKT and IPC can be considered as viable options for the treatment of primary lymphedema within stage 2 of lower limbs.
Background Launched in 2018, ’sanitary service’ aims at training all future health professionals in prevention issues, through elaborating concrete projects designed for population identified as priority. It responds to the first axe of the National Health Strategy, which is to develop a prevention and health promotion policy. In our region, about 430 actions have been implemented by 2200 students, in interdisciplinary teams. Objectives From this context occurred a reflection on how a documentary product can be used as a bridge between various health disciplines and a path to health promotion. A triple goal is pursued: provide pedagogic support, share a common view and langage, help with taking action. Results 6 theme-based document files were created. They were conceived as a collection, with a running gag in titles, colourful covers and numerous illustrations. As for promotion and dissemination, they appeared on our website, on social networks, but also (Back to the Future?) printed as proper books and sent to our partners. Our team also got involved in methodological assistance, at university and in our resource centre. Thanks to its formal innovation and its multidisciplinary audience, this production built a collective culture of health promotion. Overpassing sanitary service, it is now used by other professionals for different purposes, including project managers during training sessions. Conclusions This action faced the recurring challenge of assessing a support function such as ours, but performed in becoming a showcase to promote our structure. Information accessibility could be improved by better internet referencing, its attraction by infographics, its efficiency by evaluation. But above all, live interaction appears to be the key in a knowledge transfer strategy. Key messages Sanitary service is an opportunity to picture a common view on health promotion. As documentalists, let’s build bridges to knowledge by turning into super mediators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
