Background: A role for resistin in the pathogenesis of polycystic ovarian syndrome (PCOS) and related features were described for various ethnicities. As its expression is partly inherited, a role for RETN polymorphisms in regulating resistin levels and PCOS risk was shown, but with varied results.
Aim: To investigate the association of rs34124816 (-537A>C), rs1862513 (-420C>G), rs3219175 (-358G>A), rs3745367 (+299G>A), rs3745369 (+1263G>C), and rs1423096 (+4965C>T) RETN SNPs with PCOS.
We explored the relation between FTO single gene variants (rs1861868, rs9939973, rs1421085, rs1121980, rs17817449, rs8050136, rs9939609, rs9930506, and rs8044769) and polycystic ovary syndrome (PCOS), in particular, according to the obesity status. This retrospective population-based case-control study involved women with PCOS (583) and 713 eumenorrheic control women; genotyping was done by real-time PCR. Significantly higher minor allele frequency (MAF) of rs9939973, rs17817449, rs9939609, and rs9930506 and lower MAF of rs1121980 were seen in PCOS cases.

It is considered a grave pregnancy complication as it is associated with massive maternal hemorrhage. The condition is associated with previous cesarean delivery, multiple gestations, and increased maternal age.

Design: Study subjects comprised 583 women with PCOS and 713 age-matched controls. Genotyping of rs182052, rs822393, rs822396, rs7649121, rs3774271, rs266729, rs3774261 and rs6773957 ADIPOQ polymorphisms was done by real-time polymerase chain reaction (PCR).
Results: Of the 16 ADIPOQ variants, the minor allele frequencies of rs182052, rs822393, rs822396, rs7649121, rs3774261 and rs6773957 were significantly different between PCOS cases and controls.
Preeclampsia (PE) is a multi-system disorder that is specific to human pregnancy. Inadequate oxygenation of uterus and placenta is considered as one of the leading causes for the disease. MicroRNA-210(miR-210) is one of the prime molecules that has emerged in response to hypoxia.

Currently, RPL lacks an effective therapy and a reliable diagnostic and prognostic biomarker. Circulating microRNAs were recently described as potential biomarkers of pregnancy-associated complications.
View Article and Find Full Text PDFPreeclampsia (PE) is a pregnancy syndrome characterized by hypertension and proteinuria, and a leading cause of maternal and fetal morbidity and mortality, with poorly defined pathophysiological mechanisms remain. Circulating microRNAs (miRNAs) are small, noncoding RNA molecules, which negatively regulate gene expression, and considered as promising biomarkers for PE. The objective of the study was to evaluate circulating miRNA signatures in women with PE compared to healthy women, and in women sub-grouped per PE severity.

Methods: Case-control study involving 122 Bahraini Arab women with PCOS and 89 ethnically-matched control women. PCOS was evaluated according to 2003 Rotterdam criteria.
Background: Decreased sex hormone-binding globulin (SHBG) levels were associated with polycystic ovary syndrome (PCOS). SHBG polymorphisms associated with reduced SHBG production were tested for their association with PCOS, but with inconclusive results. We tested whether altered SHBG levels and SHBG variants were associated with PCOS.

Insofar as transcription factor 7-like 2 (TCF7L2) is consistently replicated T2DM susceptibility locus, this study evaluates whether common TCF7L2 variants are associated with PCOS and related metabolic features.
Methods: The association between TCF7L2 rs4506565, rs7903146, rs12243326, and rs12255372 SNPs and PCOS was tested in 242 women with PCOS and in 236 control women.
Objectives: To estimate the prevalence of venous thromboembolism (VTE) risk factors in pregnancy and the proportion of pregnancies at risk of VTE that received the recommended prophylaxis according to the American College of Chest Physicians (ACCP) 2012 published guidelines in antenatal clinics in the Arabian Gulf.
Methods: The evaluation of venous thromboembolism (EVE)-Risk project was a non-interventional, cross-sectional, multi-centre, multi-national study of all eligible pregnant women (≥17 years) screened during antenatal clinics from 7 centres in the Arabian Gulf countries (United Arab Emirates, Kuwait, Bahrain, Qatar and Oman). Pregnant women were recruited during a 3-month period between September and December 2012.
The aim of this study is to investigate the association of recurrent pregnancy loss (RPL) with altered C-reactive protein (CRP) serum levels, and genetic variation in CRP gene. This was a retrospective case-control study, involving 275 women with three or more consecutive pregnancy losses, and 290 age-matched control women, who were recruited from outpatient obstetrics/gynecology clinics. CRP serum levels (hs-CRP) were determined by latex-enhanced nephelometry, and CRP genotyping was done by allelic discrimination.

We investigated the association of genetic variants in FSHR and LHCGR with PCOS in Bahraini Arab women.
Methods: A retrospective case-control study, involving 203 women with PCOS, and 211 age- and ethnically-matched control women.
Study Question: Is recurrent spontaneous miscarriage (RSM) associated with changes in vascular endothelial growth factor (VEGF) serum levels, and with polymorphisms in the VEGFA gene?
Summary Answer: Reduced serum VEGF levels, and VEGFA -460T/C (rs833061), 398G/A (rs833068), -583T/C (rs3025020) variants, were associated with RSM.
What Is Known Already: Reduced expression of VEGF has been linked with spontaneous miscarriage, likely due to defective fetal and placental angiogenesis. Since VEGF production is in part inherited, VEGFA polymorphisms associated with altered VEGF secretion have been investigated for their association with RSM, often with variable conclusions.
Ovarian hyperstimulation syndrome (OHSS), ruptured ovarian cysts and bilateral ectopic pregnancies are all well-recognized entities occurring in association with infertility treatment. We are reporting a case of severe OHSS which was complicated initially by ruptured ovarian cysts and later by bilateral ectopic pregnancy. Diagnosis of tubal pregnancy was obscured by stimulated ovaries, which prevented accurate ultrasound definition.
