Observational studies suggest a longer duration of breastfeeding to be associated dose dependently with a decrease in risk of overweight in later life. The authors performed a comprehensive meta-analysis of the existing studies on duration of breastfeeding and risk of overweight. Studies were included that reported the odds ratio and 95% confidence interval(More)
Frühere Studien bei Patienten mit akutem Myokardinfarkt zeigten eine höhere Krankenhaussterblichkeit von Frauen, speziell jüngeren Frauen, im Vergleich zu Männern. Da die Behandlung des akuten Myokardinfarktes sich schnell entwickelt und nachdem geschlechtsspezifische Aspekte in den letzten Jahren detailliert diskutiert wurden, war es unser Ziel die(More)
OBJECTIVE To develop a universal guideline allowing the comparison of interventions like oral contraceptives and hormone replacement therapy with an impact on menstrual bleeding pattern. METHODS Literature analysis and cluster analysis of 4612 bleeding diaries. RESULTS We summarized key definitions needed for the evaluation of menstrual bleeding(More)
BACKGROUND Women with acute myocardial infarction (AMI) exhibit greater hospital mortality than do men. In general, diabetes mellitus is one of the major factors influencing the outcome of patients with AMI. The aim of this study was to analyze the interaction between diabetes and gender, specifically with regard to the higher hospital mortality of female(More)
OBJECTIVE In health promotion studies, young age, male gender, low education, and substance use have been found to be relevant predictors of loss to follow-up. The purpose of this study was to assess factors of loss to follow-up after screening and tailored brief advice for alcohol problems in an emergency department setting. METHOD A randomized(More)
A modeling approach termed 'nicotine bridging' is presented to estimate exposure to mainstream smoke constituents. The method is based on: (1) determination of harmful and potentially harmful constituents (HPHC) and in vitro toxicity parameter-to-nicotine regressions obtained using multiple machine-smoking protocols, (2) nicotine uptake distributions(More)
BACKGROUND The aim of this paper is to empirically identify a treatment-independent statistical method to describe clinically relevant bleeding patterns by using bleeding diaries of clinical studies on various sex hormone containing drugs. METHODS We used the four cluster analysis methods single, average and complete linkage as well as the method of Ward(More)
In 3 controlled multi-center studies, 372 patients suffering from dermatomycoses were treated with isoconazole as cream, solution, and spray either once or twice daily. Neither with regard to the duration of healing nor the healing rates were observed statistically significant differences between the two modes of treatment. As to the forms of preparation,(More)
National surveys as well as European comparative studies suggest that differences in treatment of patients with ST-elevation myocardial infarction (STEMI) exist. The extent to which these variations influence the outcome of hospital care delivered to STE-MI patients in everyday routine is mostly unknown. In this study data representative of hospital care(More)
