- Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703 healthy controls. In these 80,094 individuals of European ancestry, we identified 48 new susceptibility variants (P < 5.0 × 10(-8)), 3 of which we found after conditioning on previously identified variants. Thus, there are now 110 established multiple sclerosis risk variants at 103 discrete loci outside of the major histocompatibility complex. With high-resolution Bayesian fine mapping, we identified five regions where one variant accounted for more than 50% of the posterior probability of association. This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals.

- Objective To explore the attitudes of obstetricians to performe a caesarean section on maternal request in the absence of medical indication. Design Cluster sampling cross-sectional survey. Setting Neonatal Intensive Care Unit (NICU) associated maternity units in eight European countries. Population Obstetricians with at least 6 months clinical experience. Methods NICU-associated maternity units were chosen by census in Luxembourg, Netherlands and Sweden and by geographically stratified random sampling in France, Germany, Italy, Spain and UK. An anonymous, self-administered questionnaire was used for data collection. Main outcome measures Obstetricians' willingness to perform a caesarean section on maternal request. Results One hundred and five units and 1530 obstetricians participated in the study (response rates of 70 and 77%,respectively). Compliance with a hypothetical woman's request for elective caesarean section simply because it was 'her choice' was lowest in Spain (15%), France (19%) and Netherlands (22%); highest in Germany (75%) and UK (79%) and intermediate in the remaining countries. Using weighted multivariate logistic regression, country of practice (P < 0.001), fear of litigation (P = 0.004) and working in a university-affiliated hospital (P = 0.001) were associated with physicians' likelihood to agree to patient's request. The subset of female doctors with children was less likely to agree (OR 0.29, 95% CI 0.20-0.42). Conclusions The differences in obstetricians' attitudes are not founded on concrete medical evidence. Cultural factors, legal liability and variables linked to the specific perinatal care organisation of the various countries play a role. Greater emphasis should be placed on understanding the motivation, values and fears underlying a woman's request for elective caesarean delivery.

- OBJECTIVE: To investigate whether women who made an early sexual debut differ from those with a later debut regarding genital signs and symptoms. METHODS: The study included women who considered themselves gynecologically healthy and who attended 17 family planning centers in 13 European countries for contraceptive advice. There were 629 women who made their sexual debut at the age of 16 years or earlier (study population) and 927 women who had their first sexual intercourse at the age of 19 years or later (comparison group). Genital symptoms and signs, contraceptive use, smoking, and genital hygiene habits and previous genital infections were recorded on a structured patient record form. Detection of Chlamydia trachomatis was made by means of a polymerase chain reaction on first-void urine. The study was made, on average, 7-10 years after the women's sexual debut. RESULTS: The mean age of first intercourse was 15.3 years for the study group versus 20.7 years for the control group (p < 0.001). The study population had significantly more symptoms, such as vaginal discharge and pruritus, and signs, such as abnormal discharge, erythema of the vaginal mucosa and lower genital tract infections, than the comparison group. Twice as many women in the study group were smokers and there was a ten-fold increase among these subjects of using low-pH solutions for genital hygiene. The prevalence of C. trachomatis infection did not differ between the two groups (p = 0.22). CONCLUSION: Age at first intercourse is not only a predictor of sexual risk behavior, but also a predictor, regarding both signs and symptoms, of future gynecological problems.
