Conflict of interest between professional medical societies and industry: a cross-sectional study of Italian medical societies' websites.

OBJECTIVE: To describe how Italian medical societies interact with pharmaceutical and medical device industries through an analysis of the information available on their websites. DESIGN: Cross sectional study. SETTING: Italy. PARTICIPANTS: 154 medical societies registered with the Italian Federation of Medical-Scientific Societies. MAIN OUTCOME MEASURES: Indicators of industry sponsorship (presence of industry sponsorship in the programme of the last medical societies' annual conference; presence of manufacturers' logos on the homepage; presence of industry sponsorship of satellite symposia during the last annual conference). RESULTS: 131 Italian medical societies were considered. Of these, 4.6% had an ethical code covering relationships with industry on their websites, while 45.6% had a statute that mentioned the issue of conflict of interest and 6.1% published the annual financial report. With regard to industry sponsorship, 64.9% received private sponsorship for their last conference, 29.0% had manufacturers' logos on their webpage, while 35.9% had industry-sponsored satellite symposia at their last conference. The presence of an ethical code on the societies' websites was associated with both an increased risk of industry sponsorship of the last conference (relative risk (RR) 1.22, 95% CIs 1.01 to 1.48 after adjustment) and of conferences and/or satellite symposia (RR 1.22, 95% CIs 1.02 to 1.48 after adjustment) but not with the presence of manufacturers' logos on the websites (RR 1.79, 95% CIs 0.66 to 4.82 after adjustment). No association was observed with the other indicators of governance and transparency. CONCLUSIONS: This survey shows that industry sponsorship of Italian medical societies' conferences is common, while the presence of a structured regulatory system is not. Disclosure of the amount of industry funding to medical societies is scarce. The level of transparency therefore needs to be improved and the whole relationship between medical societies and industry should be further disciplined in order to avoid any potential for conflict of interest.

A seasonal periodicity in relapses of multiple sclerosis? A single-center, population-based, preliminary study conducted in Bologna, Italy.

BACKGROUND: Temporal, i.e., 24-hour, weekly, and seasonal patterns in the occurrence of acute cardiovascular and cerebrovascular events are well documented; however, little is known about temporal, especially seasonal, variation in multiple sclerosis (MS) and its relapses. This study investigated, by means of a validated chronobiological method, whether severe relapses of MS, ones requiring medical specialty consultation, display seasonal differences, and whether they are linked with seasonal differences in local meteorological variables. RESULTS: We considered 96 consecutive patients with severe MS relapse (29 men, 67 women, mean age 38.5 ± 8.8 years), referred to the Multiple Sclerosis Center, Bellaria Hospital, Bologna, Italy, between January 1, 2007 and December 31, 2008. Overall, we analyzed 164 relapses (56 in men, 108 in women; 115 in patients aged < 40 years, 49 in patients ≥40 years). Relapses were more frequent in May and June (12.2% each) and the least frequent in September (3.7%). Chronobiological analysis showed a biphasic pattern (major peak in May-June, secondary peak in November-December, p = 0.030). Analysis of monthly mean meteorological data showed a significant seasonal pattern in ambient temperature (peak in July, p < 0.001), relative humidity (peak in January, p < 0.001), and wind speed (peak in June, p = 0.011). CONCLUSIONS: In this Italian setting, we found a biphasic pattern (peaks in spring and autumn) in severe MS relapses requiring medical consultation by doctors of the MS specialty center, apparently unrelated to meteorological variables. Confirmations of the findings on larger multi-center populations residing in different climatic conditions are needed to further explore the potential seasonality of MS relapses and associated environmental triggers.
