First-trimester serum markers in 110 in-vitro fertilization (IVF) and 331 intracytoplasmatic sperm injection (ICSI) pregnancies were compared with 1431 pregnancies with spontaneous conception. Alterations of serum markers were evaluated with respect to small-for-gestational-age (SGA) growth and number of embryos transferred. For pregnancy-associated plasma(More)
This paper introduces a set of design principles that aim to make processor architectures amenable to static timing analysis. Based on these principles, we give a design of a hard real-time processor with predictable timing, which is simultaneously capable of reaching respectable performance levels. The design principles we identify are recoverability from(More)
OBJECTIVES To assess the spectrum of anomalies associated with fetal heart block and to identify possible prognostic markers. METHODS Retrospective review of all cases of second- or third-degree heart block identified in two tertiary referral centers in Germany (Bonn and Lübeck) and one in the USA (Baltimore). RESULTS Sixty fetuses with heart block were(More)
OBJECTIVE To determine prenatal ultrasonographic features and management of fetuses with body stalk syndrome in singleton and multiple gestations. METHODS In a retrospective chart analysis we reviewed all cases with body stalk anomaly diagnosed in our prenatal unit between 1994 and 2001. During this time period we adopted a uniform approach to the(More)
Hard real-time systems must obey strict timing constraints. Therefore, one needs to derive guarantees on the worst-case execution times of a system’s tasks. In this context, predictable behavior of system components is crucial for the derivation of tight and thus useful bounds. This paper presents results about the predictability of common cache replacement(More)
OBJECTIVE To identify specific estimates and predictors of neonatal morbidity and mortality in early onset fetal growth restriction due to placental dysfunction. METHODS Prospective multicenter study of prenatally diagnosed growth-restricted liveborn neonates of less than 33 weeks of gestational age. Relationships between perinatal variables (arterial and(More)
OBJECTIVE This study describes the frequency, pregnancy complications and outcomes of non-trichorionic triplet pregnancies. DESIGN A retrospective observational study. SETTING Two tertiary level referral centres of Obstetrics and Prenatal Medicine, Germany. POPULATION All women booked to receive targeted ultrasound screening between January 1998 and(More)
OBJECTIVE To describe the spectrum of prenatally diagnosed fetal tumors, and the course and fetal outcome in affected pregnancies. METHODS This was a retrospective study in two German tertiary referral centers of 84 fetuses with tumors diagnosed in the prenatal period. The tumors were classified according to their location and histology. RESULTS The(More)
OBJECTIVE To assess the impact of isolated lesions of the fetal right heart on ductus venosus (DV) blood flow profiles. METHODS Retrospective evaluation of DV blood flow profiles in 83 fetuses with isolated right-sided cardiac lesions. Cases were divided into two groups. Group A had right-sided cardiac lesions associated with a large ventricular septal(More)
Adhesions are believed to be one of the principal causes of chronic pelvic pain. Although there may be some discrepancy between the degree of adhesions and the severity of the symptoms, surgical adhesiolysis is still considered to be useful for the relief of pain. A total of 187 patients who underwent laparoscopic adhesiolysis at the Medical University of(More)
