Pulmonary hypertension associated to sarcoidosis in Switzerland

Introduction: L'hypertension pulmonaire est une complication rare de la sarcoïdose. Elle se rencontre surtout lors d'atteinte pulmonaire associée, particulièrement lorsque celle-ci est avancée. Objectif: Étudier l'épidémiologie et l'évolution clinique des patients souffrant d'hypertension pulmonaire et de sarcoïdose (SAPH) en Suisse. Méthode: Le registre suisse de l'hypertension pulmonaire a été analysé rétrospectivement pour identifier les cas SAPH de 2000 à 2011. Les paramètres cliniques, tels que le sexe, l'âge, le stade radiographique pulmonaire et l'hémodynamique sont étudiés lors de l'inscription des patients dans le registre. La classe fonctionnelle NYHA, la capacité à l'exercice (TM6M), les traitements introduits (oxygénothérapie, traitements spécifiques pour la sarcoïdose et traitements spécifiques pour l'hypertension pulmonaire), la survie et le nombre de transplantations pulmonaires effectués sont étudiés lors du suivi. Résultats: Parmi plus de 977 patients inscrits, 22 répondent aux critères d'inclusion pour la SAPH. La majorité de patients est de sexe féminin et l'âge moyen est de 59,5 +/-29,7. Le stade pulmonaire le plus souvent rencontré est de degré 4. La mPAP au diagnostic est de 44 ± 12.6 mmHg et la saturation veineuse d'oxygène est de 60%. La plupart des patients présentent une classe NYHA de 3 et le TM6M est de 368.6 ± 124.2 m à l'inclusion dans le registre. La durée moyenne du suivi des patients dans le registre est de 19.4 mois (0-57). La médiane est de 14 mois. La classe fonctionnelle NYHA et les moyennes des mètres parcourus ne montrent pas de changements significatifs lors du suivi. Au début de l'étude, comme à la fin, moins de la moitié des patients sont sous oxygénothérapie ; le traitement le plus utilisé pour l'hypertension pulmonaire est la classe des antagonistes de l'endothéline et pour la sarcoïdose les corticostéroïdes. La survie à un an est de 65 % et de 55 % à 3 ans. Pendant la période d'observation 5 patients nécessitent une transplantation pulmonaire, dont 2 sont décédés. La démarche médicamenteuse varie au cours du temps : la tendance récente est de donner plus de médicaments pour l'hypertension pulmonaire et la sarcoïdose et de favoriser les associations. Conclusion: La SAPH est une maladie rare ou tout au moins rarement diagnostiquée avec un sombre pronostic. Le degré d'hypertension est de modéré à sévère avec une limitation à l'effort importante. En cas de symptômes suggestifs chez un patient souffrant de sarcoïdose, un dépistage échocardiographique systématique devrait être proposé.

Obesity markers and estimated 10 year fatal cardiovascular risk in Switzerland

Objective: To assess the effectiveness of obesity markers to detect high (>5%) 10- year risk of fatal cardiovascular disease (CVD) as estimated using the SCORE function. Methods: Cross-sectional study including 3,047 women and 2,689 men aged 35-75 years (CoLaus study). Body fat percentage was assessed by tetrapolar bioimpedance. CVD risk was assessed using the SCORE risk function and gender and age-specific cut points for body fat were derived. The diagnostic accuracy of each obesity marker was evaluated through receiver operating characteristics (ROC) analysis. Results: Body fat presented a higher correlation with 10-year CVD risk than waist/hip ratio (WHR), waist or BMI: in men, r=0.31, 0.22, 0.19 and 0.12 and for body fat, WHR, waist and BMI, respectively; the corresponding values in women were 0.18, 0.15, 0.11 and 0.05, respectively (all p<0.05). In both genders, body fat showed the highest area under the ROC curve (AUC): in men, the AUC (and 95% confidence interval) were 76.0 (73.8 - 78.2), 67.3 (64.6 - 69.9), 65.8 (63.1 - 68.5) and 60.6 (57.9 - 63.5) for body fat, WHR, waist and BMI, respectively. In women, the corresponding values were 72.3 (69.2 - 75.3), 66.6 (63.1 - 70.2), 64.1 (60.6 - 67.6) and 58.8 (55.2 - 62.4). The use of body fat percentage criterion enabled to capture three times more subjects with high CVD risk than BMI criterion, and almost twice as much as WHR criterion.. Conclusions: Obesity defined by body fat percentage is more accurate to detect high 10-year risk of fatal CVD than obesity markers based on WHR, waist or BMI.

High prevalence of anorectal chlamydial infection in HIV-infected men who have sex with men in Switzerland.

Human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) were enrolled in an anorectal Chlamydia trachomatis screening study. Anorectal Chlamydia DNA was detected in 16 (10.9%) of 147 men, mainly among asymptomatic patients and patients having >20 sexual partners. These results support routine anorectal Chlamydia screening in HIV-infected MSM who report unprotected anal intercourse.

The Fairness of Media Coverage in Question: An Analysis of Referendum Campaigns on Welfare State Issues in Switzerland

The mass media are assigned an important role in political campaigns on popular votes. This article asks how the press communicates political issues to citizens during referendum campaigns, and whether some minimal criteria for successful public deliberation are met. The press coverage of all 24 ballot votes on welfare state issues from 1995 to 2004 in Switzerland is examined, distinguishing seven criteria to judge how news coverage compares to idealized notions of the media's role in the democratic process: coverage intensity, time for public deliberation, balance in media coverage, source independence and inclusiveness, substantive coverage, and spatial homogeneity. The results of our quantitative analysis suggest that the press does fulfil these normative requirements to a reasonable extent and that fears about biased or deceitful media treatment of ballot issues are not well-founded. However, some potential for optimizing the coverage of referendum campaigns by the Swiss press does exist

High prevalence of forgoing healthcare for economic reasons in Switzerland: a population-based study in a region with universal health insurance coverage.

OBJECTIVE: To investigate the determinants and the 4-year evolution of the forgoing of healthcare for economic reasons in Switzerland. METHOD: Population-based survey (2007-2010) of a representative sample aged 35-74years in the Canton of Geneva, Switzerland. Healthcare forgone, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods. RESULTS: A total of 2601 subjects were included in the analyses. Of the subjects, 13.8% (358/2601) reported having forgone healthcare for economic reasons, with the percentage varying from 3.7% in the group with a monthly income ≥13,000CHF (1CHF≈1$) to 30.9% in the group with a monthly income <3000CHF. In subjects with a monthly income <3000CHF, the percentage who had forgone healthcare increased from 22.5% in 2007/8 to 34.7% in 2010 (P trend=0.2). Forgoing healthcare for economic reasons was associated with lower income, female gender, smoking status, lower job position, having dependent children, being divorced and single, paying a higher deductible, and receiving a premium subsidy. CONCLUSION: In a Swiss region with universal health insurance coverage, the reported prevalence of forgoing healthcare for economic reasons was high and greatly dependent on socioeconomic factors. Our data suggested an increasing trend among participants with the lowest income.

Insurance coverage of pediatric burns: Switzerland versus USA.

Burn care and research have significantly improved over the past years. However, insurance coverage of such treatments does not reflect the improvements in this multi-disciplinary field. Government insurance policies in first world countries renown for burn care treatment, such as Switzerland and the United States, have not adapted to the complexity and longitudinal nature of burn care. Using case studies from both countries, we have analyzed both the institutional and policy approach to pediatric burn treatment coverage. Subsequently, by presenting the Shriners burn care model, we offer a policy recommendation to both the Swiss and the American governments to better their present legislation and infrastructure on pediatric burn coverage.

Seroepidemiology of herpes simplex virus type 1 and 2 in pregnant women in Switzerland: an obstetric clinic based study.

OBJECTIVE: To assess the seroprevalence of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) IgG antibodies and the seroincidence of HSV-1 and HSV-2 infections in pregnant women attending the maternity clinic of the University Hospital Lausanne. STUDY DESIGN: Blood samples from 1030 women were taken at the usual pregnancy visit in the first trimester to assess the prevalence rate of IgG antibodies against HSV-1 and HSV-2 using a type-specific assay. A second blood sample was taken 6-8 weeks postpartum from returning women who were seronegative for HSV-2 or HSV-1 to assess the incidence of seroconversion (primary infection). RESULTS: The seroprevalence rates were 79.4% (95% CI: 76.9-81.9) for HSV-1 and 21.2% (18.7-23.7) for HSV-2 in women 14-46 years old. Type-specific serostatus patterns were as follows: 17.3% HSV-1/-2: +/+, 62.1% HSV-1/-2: +/-, 3.9% HSV-1/-2: -/+, 16.7% HSV-1/-2: -/-. Two hundred and sixty five women (59 of the 212 seronegative for HSV-1 (27.8%) and 265 of the 812 seronegative for HSV-2 (32.6%)) returned to the outpatient clinic for the post-delivery check and a second blood sample was obtained. One HSV-1 seroconversion was detected (HSV-1 seroconversion rate 2.4%/100 patient×year (95% CI: 0.06-13.4)) in a patient who had symptoms compatible with primary genital herpes. No HSV-2 seroconversion was detected (HSV-2 seroconversion rate: 0/100 patient×year (97.5% one-sided CI: 0-2)). CONCLUSION: Compared to a previous population-based study, our study results suggest a rise in the prevalence of HSV-2 among pregnant women in Switzerland. The low incidence of seroconversion detected during pregnancy is consistent with the very low reported incidence of neonatal herpes in Switzerland. CONDENSATION: This study in a public hospital in Western Switzerland suggests an increasing prevalence of HSV-2, but a low incidence of primary infections in women of childbearing age.
