Long-term monitoring of central haemodynamics with implanted monitoring systems might be valuable in managing heart failure patients. Such systems offer an opportunity for repeated 'semi-invasive' cardiac output determinations according to the Fick principle. Five patients, four with chronic heart failure and one with chronic pulmonary disease, underwent supine exercise testing during cardiac c...

Recurrent implantation failure (RIF) is recognized when transferred embryos fail to implant following repeated in vitro fertilization (IVF) cycles [1]. RIF is commonly defined as the failure of implantation after three or more consecutive IVF attempts, with which 1-2 high-grade embryos were transferred in each cycle [2]. Cytotrophoblast invasion to the proper depth of the uterus secures proper ...

STUDY QUESTION What is the prevalence of chronic endometritis (CE) in women with repeated unexplained implantation failure (RIF) at IVF, and how does antibiotic treatment affect the reproductive outcome? SUMMARY ANSWER Chronic endometritis, associated with infection with common bacteria or mycoplasma, is common in women complaining of RIF and antibiotic treatment significantly improves the re...

Background: Implantation of vascular access devices is of great importance in critically ill patients or those vulnerable to clinical worsening. The aim of this study was to identify the complications of implantation of vascular access leading to complaints from patients, in the forensic medicine commissions of Tehran. Methods: The present descriptive-cross sectional study was performed on all...

BACKGROUND Animal models and experimental studies suggest a role for paracrine prolactin (PRL) signalling in decidualization and embryo implantation. We investigated the expression of endometrial prolactin (e-PRL) and prolactin receptor (PRL-R) in the endometrium of women affected by unexplained infertility (UI) and repeated miscarriages (RM). METHODS Patients (n = 24) were divided into three...

An intravenous injection of 2-fluoro-oestradiol simultaneously with an implantation-inducing dose of oestradiol reduced the number of implantation sites in delayed implanting hypophysectomized rats maintained with progesterone. Administration of 2-fluoro-oestradiol 1 h before or after oestradiol had no effect. Furthermore, injection of as much as 500 ng 2-fluoro-oestradiol 48 h before administr...

BACKGROUND Although embryo implantation is a prerequisite for human reproduction, it remains a poorly understood process. The molecular mechanisms regulating endometrial receptivity and/or embryo implantation are still largely unclear. METHODS Pubmed and Medline literature databases were searched for articles in English published up to December 2013 with relevant keywords including 'endometri...
