Chromosomal aberrations in pregnancy and fetal loss: Insight on the effect of consanguinity, review of 1625 cases

This study is a review of 1625 product of abortion and fetal tissue using Array comparative genomic hybridization in combination with QF ‐PCR. This is the second largest study with the main difference 35 percent of couples are related. We found a statistically significant difference between copy number variations and aneuploidies found in related versus unrelated couples. AbstractBackgroundPregnancy loss affects 10% –15% of pregnancies and is caused by several factors, maternal and fetal. Most common cause is chromosomal aneuploidy and has traditionally been detected by karyotyping product of conception and/or fetal tissue. In recent years, array comparative genomic hybridization (a‐CGH) has been used becau se of its higher detection and lower failure rates.MethodsDNA was extracted from 1625 products of abortion or fetal tissue. In 1,104 cases both quantitative fluorescent ‐polymerase chain reaction (QF‐PCR) and a‐CGH, and in 521 cases only a‐CGH, was performed.ResultsThe detection rate using QF ‐PCR and a‐CGH is 20% compared to 12.7%, overall, and 15.7%, excluding failed samples, by karyotypes in our center. QF‐PCR and a‐CGH failed in 1.9% of cases, while the failure rate for karyotypes was 20.1%. The difference of detection and failure rates is significant (p‐value

Plasma or serum kisspeptin is mainly derived from the placenta during pregnancy and plasma kisspeptin levels significantly increase across pregnancy. Plasma kisspeptin levels could be used as a potential biomarker for the detection of miscarriage, pre-eclampsia, gestational trophoblastic neoplasia (GTN), and fetal development. Kissp...

Evidence published in the Cochrane Library provides strong evidence thatfinancial incentives helped people to stop smoking and stay stopped long term.The team investigated whether rewards such as cash payments, vouchers, or the return of money deposited by those taking part, worked. The review summarizes the results from 33 randomised controlled trials involving more than 21,600 people from eight countries. They included ten trials that focused on pregnant smokers who were rewarded with vouchers for quitting and staying smoke free.The review was led by University of East Anglia (UK) and involved researchers from the Univer...

Authors: Tan H, Hu S, Qiongyu , Chen Y, Jin L, Wu C Abstract The fertility success rates of clinical and laboratory-assisted reproductive techniques (ART) remain low, despite major advances. The aim of this study was to conduct a systematic literature review and assess whether the intrauterine administration of human chorionic gonadotropin (hCG) before embryo transfer (ET) improved the clinical outcomes of sub-fertile women undergoing assisted reproduction. The electronic databases PUBMED, EMBASE and Web of Science were systematically searched for randomized controlled trials (RCTs) published from inception to June...
