Clinically relevant quality measures for risk factor control in primary care: a retrospective cohort study.

BACKGROUND: Assessment of the proportion of patients with well controlled cardiovascular risk factors underestimates the proportion of patients receiving high quality of care. Evaluating whether physicians respond appropriately to poor risk factor control gives a different picture of quality of care. We assessed physician response to control cardiovascular risk factors, as well as markers of potential overtreatment in Switzerland, a country with universal healthcare coverage but without systematic quality monitoring, annual report cards on quality of care or financial incentives to improve quality. METHODS: We performed a retrospective cohort study of 1002 randomly selected patients aged 50-80 years from four university primary care settings in Switzerland. For hypertension, dyslipidemia and diabetes mellitus, we first measured proportions in control, then assessed therapy modifications among those in poor control. "Appropriate clinical action" was defined as a therapy modification or return to control without therapy modification within 12 months among patients with baseline poor control. Potential overtreatment of these conditions was defined as intensive treatment among low-risk patients with optimal target values. RESULTS: 20% of patients with hypertension, 41% with dyslipidemia and 36% with diabetes mellitus were in control at baseline. When appropriate clinical action in response to poor control was integrated into measuring quality of care, 52 to 55% had appropriate quality of care. Over 12 months, therapy of 61% of patients with baseline poor control was modified for hypertension, 33% for dyslipidemia, and 85% for diabetes mellitus. Increases in number of drug classes (28-51%) and in drug doses (10-61%) were the most common therapy modifications. Patients with target organ damage and higher baseline values were more likely to have appropriate clinical action. We found low rates of potential overtreatment with 2% for hypertension, 3% for diabetes mellitus and 3-6% for dyslipidemia. CONCLUSIONS: In primary care, evaluating whether physicians respond appropriately to poor risk factor control, in addition to assessing proportions in control, provide a broader view of the quality of care than relying solely on measures of proportions in control. Such measures could be more clinically relevant and acceptable to physicians than simply reporting levels of control.

Violence in primary care: prevalence and follow-up of victims.

BACKGROUND: Primary care physicians underestimate the prevalence of domestic violence and community violence. Victims are therefore at risk of further episodes of violence, with psychological and physical consequences. We used an interview to assess the prevalence of domestic and community violence among Swiss natives and foreigners. In a follow-up study, we evaluated the consequences of the interview for the positive patients. METHODS: We evaluated the prevalence of violence by use of a questionnaire in an interview, in an academic general internal medicine clinic in Switzerland. In a follow-up, we evaluated the consequences of the interview for positive patients. The participants were 38 residents and 446 consecutive patients. Questionnaires were presented in the principal language spoken by our patients. They addressed sociodemographics, present and past violence, the security or lack of security felt by victims of violence, and the patients' own violence. Between 3 and 6 months after the first interview, we did a follow-up of all patients who had reported domestic violence in the last year. RESULTS: Of the 366 patients included in the study, 36 (9.8%) reported being victims of physical violence during the last year (physicians identified only 4 patients out of the 36), and 34/366 (9.3%) reported being victims of psychological violence. Domestic violence was responsible for 67.3% of the cases, and community violence for 21.8%. In 10.9% of the cases, both forms of violence were found. Of 29 patients who reported being victims of domestic violence, 22 were found in the follow-up. The frequency of violence had diminished (4/22) or the violence had ceased (17/22). CONCLUSION: The prevalence of violence is high; domestic violence is more frequent than community violence. There was no statistically significant difference between the Swiss and foreign patients' responses related to the rates of violence. Patients in a currently violent relationship stated that participating in the study helped them and that the violence decreased or ceased a few months later.

Neurobiology of addiction: the role of transcription factors CREB and C/EBP as well as that of their coactivators

Résumé Le présent travail de thèse a fait face au défi de lier les changements transcriptionnels dans les neurones du système nerveux central au développement de l'addiction aux drogues. I1 est connu que l'apprentissage induit des modifications au niveau de la structure du cerveau, principalement en changeant la manière dont les neurones sont interconnectés par des synapses. De plus en plus d'évidences soutiennent un scénario selon lequel l'activité neuronale déclenche des cascades de signalisation intracellulaire qui ciblent des facteurs de transcription. Ces derniers peuvent activer la transcription de gènes spécifiques qui codent pour des protéines nécessaires au renforcement des synapses mémorisant ainsi la nouvelle information. Puisque l'addiction peut être considérée comme une forme aberrante d'apprentissage, et que les modifications synaptiques sont connues pour être impliquées dans le processus d'addiction, nous essayons de décrire des mécanismes transcriptionels étant à la base des changements synaptiques induits par les drogues. Comme modèle nous utilisons des cultures primaires des neurones de striatum, d'hippocampe et de cortex de souris ainsi que des tranches de cerveau de rat. Une des caractéristiques communes de quasiment toutes les substances addictives est de pouvoir activer le système mésolimbique dopaminergique provoquant la libération de dopamine sur les neurones du striatum (du noyau accumbens). Dans ce travail de thèse nous démontrons que dans des cultures du striatum, la dopamine induit le facteur de transcription C/EBPβ qui, à son tour, provoque l'expression du gène codant pour la substance P. Ce mécanisme pourrait potentiellement contribuer à la tolérance envers les drogues puisqu'il fait partie d'une rétroaction (feed-back) sur les cellules produisant la dopamine. Etant donné que ces résultats montrent l'importance de C/EBPβ dans la psychopathologie de l'addiction, nous avons également décidé d'étudier les mécanismes fondamentaux de l'activation de la transcription par C/EBPβ. Nos expériences démontrent que trois isoformes activatrices de la famille C/EBP recrutent le coactivateur CBP et provoquent en même temps sa phosphorylation. Enfin, nous montrons que les coactivateurs nommés TORC, nouvellement découverts et clonés, sont capables de détecter la coïncidence d'un signal cAMP et d'une entrée de calcium dans des neurones. Par conséquent les TORCs pourraient contribuer à détecter la coïncidence d'un signal glutamate et d'un signal dopamine dans les neurones de striatum, ce qui pourrait être important pour associer les effets hédonistes de la drogue à l'information contextuelle (par exemple à l'environnement où la drogue a été consommée). Nous sommes les premiers à observer que les TORCs sont nécessaires pour la potentiation à long terme dans l'hippocampe. Summary The present thesis work faced the challenge to link the development of drug addiction to transcriptional changes in the neurons of the central nervous system. Experience and learning are known to induce structural modifications in the brain, and these changes are thought to occur mainly in the way neurons are interconnected by synapses. More and more evidences point to a scenario in which neuronal activity would activate signalization cascades that impinge on transcription factors, which, in turn, would activate genes necessary for the reinforcement of synapses coding for new informations. Given that drug addiction can be considered as an aberrant form of learning and is thought to involve synaptic modifications, we try to elucidate some of the transcriptional mechanisms that could underlie drug-induced synaptic changes. As a model system, we use primary cultures of striatal, cortical and hippocampal neurons dissected from mouse embryos as well as brain slices from rats. One of the common features of virtually all drugs of abuse is to activate the mesocorticolimbic dopaminergic system that results in the release of dopamine onto the neurons of the striatum (nucleus accumbens). In this thesis work we show that in striatal cultures, dopamine induces the transcription factor C/EBPβ that in turn drives the expression of the gene coding for substance P. This mechanism is likely to be important for the drug-induced tolerance in the brain since it might be a part of a feedback acting on dopaminergic neurons. Given the suspected importance of C/EBPβ in drug addiction, we also try to elucidate some aspects of the basic mechanisms by which the C/EBP family activates transcription. We show that three activating members of the C/EBP family recruit the coactivator CBP and trigger its phosphorylation. Finally, we demonstrate that the newly discovered and cloned transcriptional coactivators, named TORCs (transducers of regulated CREB activity) are able to detect the coincidence of a calcium and a cAMP signal in the central nervous system. This way, TORCs could contribute to the detection of a coincidence between a glutamate and a dopamine signal in striatal neurons - a process that is suggested to be important for an association between the rewarding effect of a drug and contextual information (such as the environment where the drug had been taken). We demonstrate that TORCs are required for hippocampal LTP.

Ischemic heart disease and primary care: identifying gender-related differences. An observational study

Background: Gender-related differences are seen in multiple aspects of both health and illness. Ischemic heart disease (IHD) is a pathology in which diagnostic, treatment and prognostic differences are seen between sexes, especially in the acute phase and in the hospital setting. The objective of the present study is to analyze whether there are differences between men and women when examining associated cardiovascular risk factors and secondary pharmacological prevention in the primary care setting. Methods: Retrospective descriptive observational study from January to December of 2006, including 1907 patients diagnosed with ischemic heart disease in the city of Lleida, Spain. The clinical data were obtained from computerized medical records and pharmaceutical records of medications dispensed in pharmacies with official prescriptions. Data was analyzed using bivariate descriptive statistical analysis as well as logistic regression. Results: There were no gender-related differences in screening percentages for arterial hypertension, diabetes, obesity, dyslipemia, and smoking. A greater percentage of women were hypertensive, obese and diabetic compared to men. However, men showed a tendency to achieve control targets more easily than women, with no statistically significant differences. In both sexes cardiovascular risk factors control was inadequate, between 10 and 50%. For secondary pharmaceutical prevention, the percentages of prescriptions were greater in men for anticoagulants, beta-blockers, lipid-lowering agents and angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, with age group variations up to 10%. When adjusting by age and specific diagnoses, differences were maintained for anticoagulants and lipid-lowering agents. Conclusion: Screening of cardiovascular risk factors was similar in men and women with IHD. Although a greater percentage of women were hypertensive, diabetic or obese, their management of risk factors tended to be worse than men. Overall, a poor control of cardiovascular risk factors was noted. Taken as a whole, more men were prescribed secondary prevention drugs, with differences varying by age group and IHD diagnosis.

Can smartphones and tablets improve the management of childhood illness in Tanzania? A qualitative study from a primary health care worker's perspective.

BACKGROUND: The impact of the Integrated Management of Childhood Illness (IMCI) strategy has been less than anticipated because of poor uptake. Electronic algorithms have the potential to improve quality of health care in children. However, feasibility studies about the use of electronic protocols on mobile devices over time are limited. This study investigated constraining as well as facilitating factors that influence the uptake of a new electronic Algorithm for Management of Childhood Illness (ALMANACH) among primary health workers in Dar es Salaam, Tanzania. METHODS: A qualitative approach was applied using in-depth interviews and focus group discussions with altogether 40 primary health care workers from 6 public primary health facilities in the three municipalities of Dar es Salaam, Tanzania. Health worker's perceptions related to factors facilitating or constraining the uptake of the electronic ALMANACH were identified. RESULTS: In general, the ALMANACH was assessed positively. The majority of the respondents felt comfortable to use the devices and stated that patient's trust was not affected. Most health workers said that the ALMANACH simplified their work, reduced antibiotic prescription and gave correct classification and treatment for common causes of childhood illnesses. Few HWs reported technical challenges using the devices and complained about having had difficulties in typing. Majority of the respondents stated that the devices increased the consultation duration compared to routine practice. In addition, health system barriers such as lack of staff, lack of medicine and lack of financial motivation were identified as key reasons for the low uptake of the devices. CONCLUSIONS: The ALMANACH built on electronic devices was perceived to be a powerful and useful tool. However, health system challenges influenced the uptake of the devices in the selected health facilities.

Cognitive Predictors and Risk Factors of PTSD Following Stillbirth: A Short-Term Longitudinal Study.

This short-term longitudinal study investigated cognitive predictors and risk factors of posttraumatic stress disorder (PTSD) in mothers following stillbirth. After a stillbirth at ≥ 24 weeks gestational age, 65 women completed structured clinical interviews and questionnaires assessing PTSD symptoms, cognitive predictors (appraisals, dysfunctional strategies), and risk factors (perceived social support, trauma history, obstetric history) at 3 and 6 months. PTSD symptoms decreased between 3 and 6 months (Cohen's d ranged .34-.52). Regression analyses also revealed a specific positive relationship between Rumination and concurrent frequency of PTSD symptoms (β = .45). Negative Self-View and Negative World-View related positively and Self-Blame related negatively to concurrent number of PTSD symptoms (β = .48, .44, -.45, respectively). Suppression and Distraction predicted a decrease and Numbing predicted an increase in time-lagged number of PTSD symptoms (β = -.33, -.28, .30, respectively). Risk factors for PTSD symptoms were younger age (β = -.25), lower income (β = -.29), fewer previous pregnancies (β = -.31), and poorer perceived social support (β = -.26). Interventions addressing negative appraisals, dysfunctional strategies, and social support are recommended for mothers with PTSD following stillbirth. Knowledge of cognitive predictors and risk factors of PTSD may inform the development of a screening instrument.

Medication incidents in primary care medicine: protocol of a study by the Swiss Federal Sentinel Reporting System.

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.

Factors associated with durable response to infliximab in Crohn's disease 5 years and beyond : a multicenter international cohort

BACKGROUND: Infliximab (IFX) has been used for over a decade worldwide. Less is known about the natural history of IFX use beyond a few years and which patients are more likely to sustain benefits. METHODS: Patients with Crohn's disease (CD) exposed to IFX from Massachusetts General Hospital, Boston, Saint-Antoine Hospital, Paris, and the Swiss IBD Cohort Study were identified through retrospective and prospective data collection, complemented by chart abstraction of electronic medical records. We compared long-term users of IFX (>5 yr of treatment, long-term users of infliximab [LTUI]), with non-LTUI patients to identify prognostic factors. RESULTS: We pooled data on 1014 patients with CD from 3 different databases, of whom 250 were defined as LTUI. The comparison group comprised 290 patients with CD who discontinued IFX: 48 primary nonresponses, 95 loss of responses, and 147 adverse events. Factors associated with LTUI were colonic involvements and an earlier age at the start of IFX. The prevalence of active smokers and obese patients differed markedly, but inversely, between American and European centers but did not impact outcome. The discontinuation rate was stable around 3% to 6%, each year from years 3 to 10. CONCLUSIONS: Young age at start of IFX and colonic CD are factors associated with a beneficial long-term use of IFX. After 5 years of IFX, there is still a 3% to 5% discontinuation rate annually. Several factors associated with a good initial response such as nonsmoker and shorter disease duration at IFX initiation do not seem associated with a longer term response.

Identification of potential HIV restriction factors by combining evolutionary genomic signatures with functional analyses.

BACKGROUND: Known antiretroviral restriction factors are encoded by genes that are under positive selection pressure, induced during HIV-1 infection, up-regulated by interferons, and/or interact with viral proteins. To identify potential novel restriction factors, we performed genome-wide scans for human genes sharing molecular and evolutionary signatures of known restriction factors and tested the anti-HIV-1 activity of the most promising candidates. RESULTS: Our analyses identified 30 human genes that share characteristics of known restriction factors. Functional analyses of 27 of these candidates showed that over-expression of a strikingly high proportion of them significantly inhibited HIV-1 without causing cytotoxic effects. Five factors (APOL1, APOL6, CD164, TNFRSF10A, TNFRSF10D) suppressed infectious HIV-1 production in transfected 293T cells by >90% and six additional candidates (FCGR3A, CD3E, OAS1, GBP5, SPN, IFI16) achieved this when the virus was lacking intact accessory vpr, vpu and nef genes. Unexpectedly, over-expression of two factors (IL1A, SP110) significantly increased infectious HIV-1 production. Mechanistic studies suggest that the newly identified potential restriction factors act at different steps of the viral replication cycle, including proviral transcription and production of viral proteins. Finally, we confirmed that mRNA expression of most of these candidate restriction factors in primary CD4+ T cells is significantly increased by type I interferons. CONCLUSIONS: A limited number of human genes share multiple characteristics of genes encoding for known restriction factors. Most of them display anti-retroviral activity in transient transfection assays and are expressed in primary CD4+ T cells.

Identification of novel HIV restriction factors

To efficiently replicate within mammalian cells, viruses have to manoeuvre through complex host mechanisms, hijacking a network of host proteins to achieve successful propagation. To prevent this invasion, cells have evolved over time to efficiently block the incursing pathogen by direct or indirect targeting. Human immunodeficiency virus (HIV) is a retrovirus of major global public health issue. In the last decade, extensive focus on innate immune proteins has been given, and particularly restriction factors, proteins inhibiting HIV replication by affecting various stages of the viral cycle. Because of the importance of developing new HIV therapies that are associated with reduced side effects and resistances, there is an urge to understand the antiviral response against HIV. Using common features of known restriction factors as a signature to identify new anti-HIV factors, candidates were identified. Particularly multiple members of the apolipoproteins L (APOL) family were found. Cotransfection experiments confirmed very potent inhibitory effects on HIV-1 expression. Further characterization of APOL6, the best candidate, was carried out. APOL6 was not able to inhibit HIV specifically but rather inhibited any gene-encoded DNA that was cotransfected and therefore APOL6 does not classify as a bona fide restriction factor. In addition, we were able to map the activity of APOL6 to the MAD domain and mainly to residue 174. We also found that other members of the family identified in the screen, APOL1 and 3, could have similar mechanism of action as APOL6. Finally, although the complete mechanism of action of APOL6 has yet to be elucidated, it might be blocked during transfections, potentially improving transfection of primary cells. -- Pour se répliquer efficacement dans les cellules de mammifères, les virus doivent manoeuvrer à travers des mécanismes cellulaires complexes et détourner un réseau de protéines de l'hôte. Pour empêcher cette invasion, les gènes de l'hôte ont évolué dans le temps pour cibler efficacement, directement ou indirectement, l'agent pathogène. Le virus de l'immunodéficience humaine (VIH) est un rétrovirus de problème majeur de santé publique mondiale, mais le faible risque de transmission du virus pourrait être expliqué par la présence d'un système antiviral de l'hôte qui, en cas d'échec, conduit à une infection productive. Durant la dernière décennie, il y a eu un intérêt spécial porté sur les protéines immunitaires innées appelé facteurs de restriction présentant des effets inhibiteurs puissants sur la réplication du VIH en affectant différentes étapes du cycle viral. En raison de l'importance de la recherche de nouvelles thérapies anti-VIH associées à des effets secondaires et des résistances réduites comparé aux traitements actuels, il existe un besoin de comprendre la réponse antivirale innée contre le VIH. Basé sur des caractéristiques communes des facteurs de restriction connus, nous avons proposé d'identifier de nouveaux facteurs anti-VIH. Nous avons trouvé une famille de protéines, les apolipoprotéines L (APOL) montrant les effets inhibiteurs très puissants contre l'expression du VIH-1 dans des expériences de co-transfection. Nous avons décidé d'approfondir le rôle de ces protéines dans l'immunité innée et de se concentrer sur le meilleur candidat APOL6. Nous avons en outre établi qu'APOL6 n'a pas d'activité anti-virale spécifique et donc pas classé comme un facteur de bonne foi de restriction. Par ailleurs, APOL6 est capable d'inhiber fortement l'expression de tout Plasmide cotransfecté. En outre, nous avons été en mesure de cartographier l'activité d'APOL6 au domaine MAD et principalement au résidu 174. Nous avons également constaté que d'autres membres de la famille identifiés dans l'étude, APOL1 et 3, pourraient avoir le même mécanisme d'action qu'APOL6. Enfin, bien que le mécanisme d'action complet d'APOL6 reste à être élucidé, il pourrait être d'une importance biotechnologique car il pourrait potentiellement faciliter la transfection de cellules primaires après l'inhibition d'APOL6.

Importància dels factors de risc del TDH en l'adquisició de la lecto-escriptura

A l’actualitat, molts infants distrets i moguts són etiquetats de TDAH. Aquest trastorn és objecte d’estudi en els últims anys dins l’educació, sobretot en els cicles d’educació infantil i primària. És un fet que preocupa a molts professionals, ja que desenvolupa unes mancances i necessitats educatives especials, que afecten al rendiment acadèmic del nen/a. El propòsit d’aquesta recerca és analitzar la correlació entre els factors de risc de TDAH i les dificultats lingüístiques, concretament amb els problemes de la consciència fonològica. Per observar aquesta qüestió s’ha partit d’una mostra de vint-i-quatre alumnes de segon cicle d’Educació Infantil i se’ls ha passat dos tests; un per avaluar els factors de risc de TDAH i l’altre per valorar el nivell de consciència fonològica. I amb els resultats obtinguts, s’ha dissenyat una intervenció que atent a la diversitat i intenta millorar aquestes dificultats lingüístiques que presenten els infants.

Responding to Young People's Health Risks in Primary Care: A Cluster Randomised Trial of Training Clinicians in Screening and Motivational Interviewing.

OBJECTIVE: To evaluate the effectiveness of a complex intervention implementing best practice guidelines recommending clinicians screen and counsel young people across multiple psychosocial risk factors, on clinicians' detection of health risks and patients' risk taking behaviour, compared to a didactic seminar on young people's health. DESIGN: Pragmatic cluster randomised trial where volunteer general practices were stratified by postcode advantage or disadvantage score and billing type (private, free national health, community health centre), then randomised into either intervention or comparison arms using a computer generated random sequence. Three months post-intervention, patients were recruited from all practices post-consultation for a Computer Assisted Telephone Interview and followed up three and 12 months later. Researchers recruiting, consenting and interviewing patients and patients themselves were masked to allocation status; clinicians were not. SETTING: General practices in metropolitan and rural Victoria, Australia. PARTICIPANTS: General practices with at least one interested clinician (general practitioner or nurse) and their 14-24 year old patients. INTERVENTION: This complex intervention was designed using evidence based practice in learning and change in clinician behaviour and general practice systems, and included best practice approaches to motivating change in adolescent risk taking behaviours. The intervention involved training clinicians (nine hours) in health risk screening, use of a screening tool and motivational interviewing; training all practice staff (receptionists and clinicians) in engaging youth; provision of feedback to clinicians of patients' risk data; and two practice visits to support new screening and referral resources. Comparison clinicians received one didactic educational seminar (three hours) on engaging youth and health risk screening. OUTCOME MEASURES: Primary outcomes were patient report of (1) clinician detection of at least one of six health risk behaviours (tobacco, alcohol and illicit drug use, risks for sexually transmitted infection, STI, unplanned pregnancy, and road risks); and (2) change in one or more of the six health risk behaviours, at three months or at 12 months. Secondary outcomes were likelihood of future visits, trust in the clinician after exit interview, clinician detection of emotional distress and fear and abuse in relationships, and emotional distress at three and 12 months. Patient acceptability of the screening tool was also described for the intervention arm. Analyses were adjusted for practice location and billing type, patients' sex, age, and recruitment method, and past health risks, where appropriate. An intention to treat analysis approach was used, which included multilevel multiple imputation for missing outcome data. RESULTS: 42 practices were randomly allocated to intervention or comparison arms. Two intervention practices withdrew post allocation, prior to training, leaving 19 intervention (53 clinicians, 377 patients) and 21 comparison (79 clinicians, 524 patients) practices. 69% of patients in both intervention (260) and comparison (360) arms completed the 12 month follow-up. Intervention clinicians discussed more health risks per patient (59.7%) than comparison clinicians (52.7%) and thus were more likely to detect a higher proportion of young people with at least one of the six health risk behaviours (38.4% vs 26.7%, risk difference [RD] 11.6%, Confidence Interval [CI] 2.93% to 20.3%; adjusted odds ratio [OR] 1.7, CI 1.1 to 2.5). Patients reported less illicit drug use (RD -6.0, CI -11 to -1.2; OR 0·52, CI 0·28 to 0·96), and less risk for STI (RD -5.4, CI -11 to 0.2; OR 0·66, CI 0·46 to 0·96) at three months in the intervention relative to the comparison arm, and for unplanned pregnancy at 12 months (RD -4.4; CI -8.7 to -0.1; OR 0·40, CI 0·20 to 0·80). No differences were detected between arms on other health risks. There were no differences on secondary outcomes, apart from a greater detection of abuse (OR 13.8, CI 1.71 to 111). There were no reports of harmful events and intervention arm youth had high acceptance of the screening tool. CONCLUSIONS: A complex intervention, compared to a simple educational seminar for practices, improved detection of health risk behaviours in young people. Impact on health outcomes was inconclusive. Technology enabling more efficient, systematic health-risk screening may allow providers to target counselling toward higher risk individuals. Further trials require more power to confirm health benefits. TRIAL REGISTRATION: ISRCTN.com ISRCTN16059206.

Multimorbidity in primary care : protocol of a national cross-sectional study in Switzerland.

INTRODUCTION: With the ageing of the population and the general improvement of care, an increasing number of people are living with multiple chronic health conditions or 'multimorbidity'. Multimorbidity often implies multiple medical treatments. As a consequence, the risk of adverse events and the time spent by patients for their treatments increase exponentially. In many cases, treatment guidelines traditionally defined for single conditions are not easily applicable. Primary care for individuals with multimorbidity requires complex patient-centred care and good communication between the patient and the general practitioner (GP). This often includes prioritising among the different chronic conditions. METHODS AND ANALYSIS: The main objectives of this study are to describe the burden related to multimorbidity (disease-related burden and burden of treatment) in primary care and to identify the factors influencing it. Other objectives include evaluating patients' perception of treatment burden and quality of life, assessing factors influencing that perception, and investigating prioritisation in the management of multimorbidity from the perspectives of GPs and patients. For this cross-sectional study, patient enrolment will take place in GP's private practices across Switzerland. A convenient sample of 100 GPs will participate; overall, 1000 patients with at least three chronic health conditions will be enrolled. Data will be collected as paper-based questionnaires for GPs and delayed telephone interview questionnaires for patients. GPs will provide demographic and practice-related data. In addition, each GP will complete a paper-based questionnaire for each patient that they enrol. Each patient will complete a telephone interview questionnaire. ETHICS AND DISSEMINATION: This study has been approved by the research ethics committee of Canton Vaud, Switzerland (Protocol 315/14). The results of the study will be reported in international peer-reviewed journals.

Prise en charge de la candidose oesophagienne en médecine de premier recours [Management of the esophageal candidiasis by the primary care physician].

La candidose oesophagienne est l'une des infections opportunistes les plus fréquentes chez les patients infectés par le VIH. Ce diagnostic se rencontre également chez des patients sans immunodéficience manifeste. Certains facteurs de risque sont également associés à cette pathologie, tels que les traitements corticoïdes systémiques et inhalés ou les traitements par inhibiteurs de la pompe à protons et les antihistaminiques H2. En l'absence de facteur de risque identifié, un déficit immunitaire primaire devrait être recherché. La prévention de la candidose oesophagienne est basée en premier lieu sur l'identification des facteurs de risque, ainsi qu'un meilleur contrôle de ceux-ci. Cet article présente en détail la physio-pathologie, la clinique et la prise en charge par le médecin de premier recours de la candidose oesophagienne. Nous aborderons également les moyens de prévention de la candidose oesophagienne quand il y a lieu. Esophageal candidiasis is one of the most common opportunistic infections in patients infected by human immunodeficiency virus (HIV). This pathology is also found in patients without overt immunodeficiency. Other risk factors are known to be associated with this disease like inhaled or systemic corticosteroid treatment or proton-pump inhibitors and H2 receptor antagonists. In the absence of identified risk factors, a primary immune deficiency should be sought. Prevention of esophageal candidiasis is based primarily on the identification of risk factors, and a better control of them. This article presents a review of the physiopathology, clinical presentation and management of esophageal candidiasis by primary care physicians. We will also discuss ways of preventing esophageal candidiasis when necessary.

Statines en prévention primaire: comment décider avec le patient [Statins in primary prevention: how to share the decision?].

Long-term treatment of hypercholesterolemia with statins diminishes the risk of cardiovascular events. Statins are recommended in secondary prevention of cardiovascular disease. In the absence of preexisting cardiovascular disease, the decision to start a statin or not is most often made by the general practitioner and his patient. An interactive decision aid, developed by the Mayo Clinic, has just been translated in French and adapted to the Swiss epidemiology of cardiovascular risk factors, with the aim of promoting shared decision-making. This paper reviews the conditions and potential benefits of shared decision-making about statin therapy in primary prevention.
