Breakthrough technologies which now enable the sequencing of individual genomes will irreversibly modify the way diseases are diagnosed, predicted, prevented and treated. For these technologies to reach their full potential requires, upstream, access to high-quality biomedical data and samples from large number of properly informed and consenting individuals and, downstream, the possibility to transform the emerging knowledge into a clinical utility. The Lausanne Institutional Biobank was designed as an integrated, highly versatile infrastructure to harness the power of these emerging technologies and catalyse the discovery and development of innovative therapeutics and biomarkers, and advance the field of personalised medicine. Described here are its rationale, design and governance, as well as parallel initiatives which have been launched locally to address the societal, ethical and technological issues associated with this new bio-resource. Since January 2013, inpatients admitted at Lausanne CHUV University Hospital have been systematically invited to provide a general consent for the use of their biomedical data and samples for research, to complete a standardised questionnaire, to donate a 10-ml sample of blood for future DNA extraction and to be re-contacted for future clinical trials. Over the first 18 months of operation, 14,459 patients were contacted, and 11,051 accepted to participate in the study. This initial 18-month experience illustrates that a systematic hospital-based biobank is feasible; it shows a strong engagement in research from the patient population in this University Hospital setting, and the need for a broad, integrated approach for the future of medicine to reach its full potential.

BACKGROUND/RATIONALE: Patient safety is a major concern in healthcare systems worldwide. Although most safety research has been conducted in the inpatient setting, evidence indicates that medical errors and adverse events are a threat to patients in the primary care setting as well. Since information about the frequency and outcomes of safety incidents in primary care is required, the goals of this study are to describe the type, frequency, seasonal and regional distribution of medication incidents in primary care in Switzerland and to elucidate possible risk factors for medication incidents. Label="METHODS AND ANALYSIS" ="METHODS"/> <AbstractText STUDY DESIGN AND SETTING: We will conduct a prospective surveillance study to identify cases of medication incidents among primary care patients in Switzerland over the course of the year 2015. PARTICIPANTS: Patients undergoing drug treatment by 167 general practitioners or paediatricians reporting to the Swiss Federal Sentinel Reporting System. INCLUSION CRITERIA: Any erroneous event, as defined by the physician, related to the medication process and interfering with normal treatment course. EXCLUSION CRITERIA: Lack of treatment effect, adverse drug reactions or drug-drug or drug-disease interactions without detectable treatment error. PRIMARY OUTCOME: Medication incidents. RISK FACTORS: Age, gender, polymedication, morbidity, care dependency, hospitalisation. STATISTICAL ANALYSIS: Descriptive statistics to assess type, frequency, seasonal and regional distribution of medication incidents and logistic regression to assess their association with potential risk factors. Estimated sample size: 500 medication incidents. LIMITATIONS: We will take into account under-reporting and selective reporting among others as potential sources of bias or imprecision when interpreting the results. ETHICS AND DISSEMINATION: No formal request was necessary because of fully anonymised data. The results will be published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT0229537.

Many people regard the concept of hypothesis testing as fundamental to inferential statistics. Various schools of thought, in particular frequentist and Bayesian, have promoted radically different solutions for taking a decision about the plausibility of competing hypotheses. Comprehensive philosophical comparisons about their advantages and drawbacks are widely available and continue to span over large debates in the literature. More recently, controversial discussion was initiated by an editorial decision of a scientific journal [1] to refuse any paper submitted for publication containing null hypothesis testing procedures. Since the large majority of papers published in forensic journals propose the evaluation of statistical evidence based on the so called p-values, it is of interest to expose the discussion of this journal's decision within the forensic science community. This paper aims to provide forensic science researchers with a primer on the main concepts and their implications for making informed methodological choices.

The evaluation of forensic evidence can occur at any level within the hierarchy of propositions depending on the question being asked and the amount and type of information that is taken into account within the evaluation. Commonly DNA evidence is reported given propositions that deal with the sub-source level in the hierarchy, which deals only with the possibility that a nominated individual is a source of DNA in a trace (or contributor to the DNA in the case of a mixed DNA trace). We explore the use of information obtained from examinations, presumptive and discriminating tests for body fluids, DNA concentrations and some case circumstances within a Bayesian network in order to provide assistance to the Courts that have to consider propositions at source level. We use a scenario in which the presence of blood is of interest as an exemplar and consider how DNA profiling results and the potential for laboratory error can be taken into account. We finish with examples of how the results of these reports could be presented in court using either numerical values or verbal descriptions of the results.

Une préoccupation essentielle traverse cette thèse: l'indifférence systémique de la Loi internationale sur la propriété intellectuelle a l'égard des savoirs traditionnels autochtones. De manière générale, un écart semble d'ailleurs croissant entre l'importance des accords internationaux sur les questions d'intérêt commercial et ceux de nature sociale. Les savoirs traditionnels autochtones sur les plantes médicinales sont particulièrement désavantagés dans ce système dichotomique puisqu'ils sont non seulement à l'origine d'énormes profits commerciaux mais se trouvent aussi au cÅur de multiples croyances propres à ces sociétés. L'Accord sur les aspects des droits de propriété intellectuelle qui touchent au commerce (ADPIC) de l'Organisation mondiale du commerce (OMC) a cristallisé le souci de la législation internationale à l'égard d'une protection efficace des intérêts commerciaux. Deux années auparavant, la Convention sur la diversité biologique (CDB) était signée, traduisant une préoccupation à l'égard du développement durable, et elle devenait le premier accord international à tenir compte des savoirs traditionnels autochtones. On considère souvent que ces deux accords permettent l'équilibre du développement commercial et durable, requis par l'économie internationale. Après plus ample examen, on a plutôt l'impression que l'idée d'une CDB défendant, avec succès et efficacité, la nécessité du développement durable et des savoirs traditionnels autochtones contre les pressions opposées de l'ADPIC et de l'OMC est, au mieux, simpliste. La thèse explore également la fonction de la Loi sur les brevets dans la création dâindustries, notamment pharmaceutique, et la manière dont ces industries influencent la législation nationale et en particulier internationale. De même, elle traite du rôle que jouent les brevets dans l'affaiblissement et la dépossession des peuples autochtones dotés de savoirs traditionnels sur les plantes médicinales, conduisant à une situation ou ces savoirs sont marginalisés ainsi que leurs détenteurs. La thèse aborde les failles institutionnelles du système juridique international qui permet une telle situation et indique l'urgente nécessité d'examiner attentivement les inégalités économiques et sociales au Nord comme au Sud, et non seulement entre eux. Finalement, la thèse suggère que la législation internationale gagnerait à s'inspirer des diverses traditions juridiques présentes à travers le monde et, dans ce cas particulier, peut être les détenteurs des connaissances traditionnelles concernant les plantes médicinales seront mieux servi par le droit des obligations.

Le mal de ventre chez les enfants est un lieu de métissage et de créolisation traversé par des dimensions sociales et culturelles. Il est construit collectivement au sein des familles nucléaires avec leurs parcours migratoires et leurs souffrances. Par le biais dâentretiens menés auprès de familles haïtiennes vivant à Montréal, nous documentons les trajectoires de ces douleurs, dans lesquelles les perceptions, les explications et les moyens mis en Åuvre pour les soulager interagissent dâune manière dynamique. En général, les enfants perçoivent leurs maux de ventre comme une expérience insaisissable, diffuse et ayant un impact sur leur vie sociale, tout en étant tolérés par les enfants et par les mères. Ces familles nâont pas reçu de diagnostic médical et elles attribuent à ces maux des explications provisoires en constante recomposition. En général, elles ont recours à différentes méthodes de prise en charge des maux de ventre. Lâespace familial, les activités réalisées au sein des églises et la médecine officielle sont des espaces thérapeutiques privilégiés.
