Autologous endometrial cell co-culture improves human embryo development to high-quality blastocysts: a randomized controlled trial.

Research Question: Does autologous endometrial cell co-culture (AECC) improve the number of good-quality blastocysts obtained by IVF/intracytoplasmic sperm injection (ICSI), compared with conventional embryo culture medium in a broad group of patients referred to assisted reproductive technology (ART)?

Design: This interventional, randomized, double-blind study took place at Clinique Ovo from March 2013 to October 2015 and included 207 healthy patients undergoing an IVF or ICSI protocol, of which 71 were excluded before randomization. On the previous cycle, all participants underwent an endometrial biopsy at D5 to D7 post-ovulation, following which the endometrial cells were prepared for AECC.

Results: The data demonstrated that AECC significantly increased the incidence of good-quality blastocysts compared with culture in conventional media (42.

Neuroinflammation in acute liver failure: mechanisms and novel therapeutic targets.

It is increasingly evident that neuroinflammatory mechanisms are implicated in the pathogenesis of the central nervous system (CNS) complications (intracranial hypertension, brain herniation) of acute liver failure (ALF). Neuroinflammation in ALF is characterized by microglial activation and arterio-venous difference studies as well as studies of gene expression confirm local brain production and release of proinflammatory cytokines including TNF-α and the interleukins IL-1β and IL-6. Although the precise nature of the glial cell responsible for brain cytokine synthesis is not yet established, evidence to date supports a role for both astrocytes and microglia.

Successful pregnancy in an ovarian agenesis patient after modified natural cycle IVF oocyte donation.

The recovery of a mature oocyte from a modified natural cycle followed by in-vitro fertilization (nIVF) is an attractive alternative to conventional IVF, involving ovarian stimulation, in the treatment of female infertility. Ovarian agenesis is a rare disorder resulting in primary amenorrhoea and infertility in affected females. A couple sought help for infertility due to ovarian agenesis of the female partner and decided to pursue treatment utilizing oocyte donation.

eNOS gene deletion restores blood-brain barrier integrity and attenuates neurodegeneration in the thiamine-deficient mouse brain.

Wernicke's encephalopathy is a cerebral disorder caused by thiamine (vitamin B(1)) deficiency (TD). Neuropathologic consequences of TD include region-selective neuronal cell loss and blood-brain barrier (BBB) breakdown. Early increased expression of the endothelial isoform of nitric oxide synthase (eNOS) occurs selectively in vulnerable brain regions in TD.

Thiamine deficiency-related brain dysfunction in chronic liver failure.

End-stage chronic liver failure results in thiamine deficiency caused principally by depletion of liver thiamine stores. Chronic liver failure also leads to increased brain ammonia concentrations. Both ammonia and thiamine deficiency result in decreased activity of alpha-ketoglutarate dehydrogenase, a rate-limiting tricarboxylic acid cycle enzyme.

Vasa praevia after IVF: should there be guidelines? Report of two cases and literature review.

The paper gives an illustration and reminder of the risk of problems with placentation resulting from IVF and embryo transfer. Reported here is one neonatal death related to vasa praevia when the condition was not diagnosed antenatally and a neonatal survival when vasa praevia was detected antenatally. A search of the English literature was performed using PubMed for 'vasa praevia and in vitro fertilization'.

Ongoing pregnancy after ICSI of frozen-thawed PESA-retrieved spermatozoa and IVF in a controlled natural cycle.

The recovery of a mature oocyte from a natural cycle followed by IVF (nIVF) is an attractive alternative to conventional IVF, involving ovarian stimulation, in the treatment of female infertility. Similarly, surgical recovery of spermatozoa from the epididymis by percutaneous sperm aspiration (PESA) has simplified the treatment of men with obstructive azoospermia. A couple sought treatment for diminished ovarian reserve and male factor infertility using IVF.
