Bibliographic study showed improving methodology of meta-analyses published in leading journals 1993-2002

OBJECTIVE: To assess the methodology of meta-analyses published in leading general and specialist medical journals over a 10-year period. STUDY DESIGN AND SETTING: Volumes 1993-2002 of four general medicine journals and four specialist journals were searched by hand for meta-analyses including at least five controlled trials. Characteristics were assessed using a standardized questionnaire. RESULTS: A total of 272 meta-analyses, which included a median of 11 trials (range 5-195), were assessed. Most (81%) were published in general medicine journals. The median (range) number of databases searched increased from 1 (1-9) in 1993/1994 to 3.5 (1-21) in 2001/2002, P<0.0001. The proportion of meta-analyses including searches by hand (10% in 1993/1994, 25% in 2001/2002, P=0.005), searches of the grey literature (29%, 51%, P=0.010 by chi-square test), and of trial registers (10%, 32%, P=0.025) also increased. Assessments of the quality of trials also became more common (45%, 70%, P=0.008), including whether allocation of patients to treatment groups had been concealed (24%, 60%, P=0.001). The methodological and reporting quality was consistently higher in general medicine compared to specialist journals. CONCLUSION: Many meta-analyses published in leading journals have important methodological limitations. The situation has improved in recent years but considerable room for further improvements remains.

The extreme flood event of Lago Maggiore in September 1993

In September 1993, the Valais and Ticino regions of Switzerland were affected by extreme flooding triggered by heavy precipitation. The meteorological situation leading to this event is studied in the Twentieth Century Reanalysis (20CR) data set. A strong cut-off low development is found to be the driving synoptic-scale atmospheric circulation pattern. The agreement with previous studies highlights the applicability of 20CR for extreme event analysis.

Two Decades of Measuring Environmental Attitudes: An Analysis of the ISSP Environmental Modules 1993, 2000, and 2010

This paper analyzes the development of environmental concern by using the three waves of the environmental modules of the International Social Survey Programme (ISSP). First, we discuss the measurement of environmental concern and construct a ranking of countries according to the new 2010 ISSP results. Second, we analyze the determinants of environmental concern by employing multilevel models that take individual as well as context effects into account. Third, we explore the impact of attitudes on environmental behavior and support of environmental policies. The results show that environmental concern is closely correlated with the wealth of nations. However, environmental concern decreased in OECD as well as non-OECD nations slightly during the last two decades. The decline was lower in countries with improving economic conditions suggesting that economic growth helps to maintain higher levels of environmental concern. Furthermore, attitudes have a stronger impact on support of environmental policies as compared to everyday environmental behavior.

Congential syphilis in Harris County, Texas, 1993--1996

The specific aims of this study were to: (1) To determine the incidence of congenital syphilis (CS) for the 1993-96 birth cohorts in Houston/Harris County, based on the newly revised 1989 CS surveillance definition in Houston/Harris County, Texas; (2) To study the distribution of selected variables listed in the Centers for Disease Control and Prevention (CDC) Congenital Syphilis Case Investigation and Report Form for the reported cases of CS; (3) To ascertain the relationships of maternal demographic factors, geographic distribution, and provision and utilization of prenatal care, associated with reported congenital syphilis delivery.^ This was a descriptive study analyzing reported cases of congenital syphilis in Houston/Harris, County, TX during the years 1993-96 using the data recorded on the CDC's Congenital Syphilis Case Investigation and Report forms. The population included infants delivered during 1993-96 who were diagnosed with congenital syphilis, using the revised 1990 criteria of the CDC. This study examined the risk factors associated with the occurrence of congenital syphilis in Harris County where the prevalence of maternal syphilis infection (13.7/100,000/1995) is high.

A Census of Eddy Activities in the South China Sea During 1993-2007

Numerous mesoscale eddies occur each year in the South China Sea (SCS), but their statistical characteristics are still not well documented. A Pacific basin-wide three dimensional physical-biogeochemical model has been developed and the result in the SCS subdomain is used to quantify the eddy activities during the period of 1993-2007. The modeled results are compared with a merged and gridded satellite product of sea level anomaly by using the same eddy identification and tracking method. On average, there are about 32.9 +/- 2.4 eddies predicted by the model and 32.8 +/- 3.4 eddies observed by satellite each year, and about 52% of them are cyclonic eddies. The radius of these eddies ranges from about 46.5 to 223.5 km, with a mean value of 87.4 km. More than 70% of the eddies have a radius smaller than 100 km. The mean area covered by these eddies each year is around 160,170 km(2), equivalent to 9.8% of the SCS area with water depths greater than 1000 m. Linear relationships are found between eddy lifetime and eddy magnitude and between eddy vertical extent and eddy magnitude, showing that strong eddies usually last longer and penetrate deeper than weak ones. Interannual variations in eddy numbers and the total eddy-occupied area indicate that eddy activities in the SCS do not directly correspond to the El Nino-Southern Oscillation events. The wind stress curls are thought to be an important but not the only mechanism of eddy genesis in the SCS.

Escalating incidence of eosinophilic esophagitis in Canton of Vaud, Switzerland, 1993-2013: a population-based study.

BACKGROUND Eosinophilic esophagitis (EoE) is a chronic, inflammatory disease of the esophagus with a rapidly increasing incidence. However, population-based epidemiologic data on EoE are rare and limited to regions with less than 200 000 inhabitants. We evaluated the incidence and prevalence of EoE over time in Canton of Vaud, Switzerland. MATERIALS AND METHODS Canton of Vaud lies in the French-speaking, Western part of Switzerland. As of December 2013, it had a population of 743 317 inhabitants. We contacted all pathology institutes (n = 6) in this canton to identify patients that have been diagnosed with esophageal eosinophilia between 1993 and 2013. We then performed a chart review in all adult and pediatric gastroenterology practices to identify patients with EoE. RESULTS Of 263 patients with esophageal eosinophilia, a total of 179 fulfilled the diagnostic criteria for EoE. Median diagnostic delay was 4 (IQR 1-9) years. No patient was diagnosed with EoE prior to 2003. Incidence of EoE increased from 0.16/100 000 inhabitants in 2004 to 6.3/100 000 inhabitants in 2013 (P < 0.001). The cumulative EoE prevalence in 2013 was 24.1/100 000. The incidence in males was 2.8 times higher (95% CI 2.01-3.88, P < 0.001) when compared to that in females. The annual EoE incidence was 10.6 times higher (95%-CI 7.61-14.87, P < 0.001) in the period from 2010 to 2013 when compared to that in the period from 1993 to 2009. CONCLUSIONS The incidence and cumulative prevalence of EoE in Canton of Vaud, Switzerland, has rapidly increased in the past 10 years.
