A randomized controlled trial of vaginal progesterone for luteal phase support in modified natural cycle - frozen embryo transfer.

Objective: Our aim was to study whether luteal phase support (LPS) increases the live-birth rate (LBR) in women undergoing modified natural cycle (mNC) frozen-thawed embryo transfer (FET).

Methods: In a randomized controlled trial, conducted at a university-affiliated tertiary medical center, a total of 59 patients aged 18-45 years, underwent mNC-FET. FET was performed in mNC following ovulation triggering by hCG.

Risk of Mesh Erosion after Pelvic Organ Prolapse Repair with or without Concomitant Vaginal Hysterectomy.

Background: Hysterectomy is common in the management of symptomatic uterine prolapse. Vaginal wall repair is often necessary, for which vaginal mesh remains a popular option.

Objectives: To evaluate the risk of mesh erosion following mesh-augmented vaginal prolapse repair, with or without concomitant vaginal hysterectomy.

Screening for blood born viruses in assisted reproduction: is annual testing necessary?

Purpose: Screening for blood born viruses is routinely performed before fertility treatment in assisted reproduction technology (ART) clinics worldwide. It involves testing for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), among others. Identifying patients with positive viral screening allows to refer them and their partners for appropriate counseling and treatment.

Villitis of unknown etiology - prevalence and clinical associations.

Objectives: We aimed to determine the association of villitis of unknown etiology (VUE) in complicated and uncomplicated pregnancies.

Methods: Placentas from term pregnancies (≥37 weeks) were sent to histopathology evaluation. Maternal and labor characteristics and pathological reports were compared between placentas with VUE (VUE group) and without VUE (controls).

The placental component in early-onset and late-onset preeclampsia in relation to fetal growth restriction.

Objective: To identify pathological placental differences between early-onset and late-onset preeclampsia, in relation to fetal growth restriction (FGR).

Methods: Placentas from patients with preeclampsia were analyzed for lesions of maternal vascular supply consistent with maternal underperfusion and lesions of fetal vascular supply consistent with fetal thrombo-occlusive disease. Findings were compared between patients who gave birth before 34 weeks (early-onset preeclampsia) and after 34 weeks (late-onset preeclampsia).
