Effect of endometriosis activity on pregnancy outcome in patients with repeated implantation failure
Background: Recurrent pregnancy loss (RPL), defined as 3 or more consecutive pregnancy failures, is a common and distressing disorder. Chromosome instability in the conceptus is the most common cause whereas uterine factors are invariably invoked to explain nonchromosomal miscarriages. These uterine factors are, however, poorly defined. Materials amd Methods: Laboratory-based analysis of endome...
This study investigates procedures for controlling the familywise error rate (FWR) when testing hypotheses about multiple, correlated outcome variables in repeated measures (RM) designs. A content analysis of RM research articles published in 4 psychology journals revealed that 3 quarters of studies tested hypotheses about 2 or more outcome variables. Several procedures originally proposed for ...
BACKGROUND The technical aspects of ductal stenting have been reported, but little is known of the fate of the duct after stent implantation. METHODS AND RESULTS Nineteen patients underwent stent implantation to maintain ductal patency. Eight had hypoplastic left heart (HLH) syndrome, 10 had pulmonary atresia, and 1 had tricuspid atresia. Median survival with HLH was 57 (12 to 907) days. Sten...
The evolution of regular chorionic gonadotropin (CG) and hyperglycosylated CG are linked with the evolution of hemochorial placentation in primates. Recent research with humans shows that regular CG promotes spiral artery angiogenesis and hyperglycosylated CG controls invasion by implanting trophoblast cells. It is inferred that the evolution of regular CG and hyperglycosylated CG in early simi...
Aim. The aim of the study was to evaluate long-term results implantation domestic endocardial leads (EL) with active fixation ELBI 233C-53 and 233C-58, implanted in atrial ventricular positions, respectively. Methods. A total 165 patients were included retrospective, single-center study. 239 EL from 2016 2018 (55 184 233C-58). median age 78 years (43 92 years). 846 programming protocols analyze...
In the past 20 years a variety of electronic markets have been set-up for the allocation of capacities in road transportation. Although, inefficiencies and cost pressures are high, the electronic markets have not succeeded so far. In this paper we will give an overview of the so-called electronic transportation exchanges and analyze the factors that were involved in the repeated failures. By us...
BACKGROUND The clinical characteristics and prognosis of elderly patients with Brugada syndrome (BrS) are largely unknown. The purpose of this study was to evaluate the risks and benefits of implantable cardioverter defibrillator (ICD) in elderly patients with BrS based on a long follow-up. METHODS AND RESULTS A total of 120 BrS patients with ICD (90 for aborted sudden cardiac arrest or synco...
