Psychometric properties of the Greek versions of the Pandemic-Related Pregnancy Stress Scale and the Pandemic-Related Postpartum Stress Scale and associated risk factors during the second year of the COVID-19 pandemic.

Background: The COVID-19 pandemic has affected perinatal mental health. Reliable tools are needed to assess perinatal stress during pandemic situations.

Aims: To assess the psychometric properties of the Greek versions of the Pandemic-Related Pregnancy Stress Scale (PREPS) and the Pandemic-Related Postpartum Stress Scale (PREPS-PP) and to explore the associations between women's characteristics and perinatal stress during the second pandemic wave.

Obstetric outcomes after treatment of periodontal disease during pregnancy: systematic review and meta-analysis.

Objective: To examine whether treatment of periodontal disease with scaling and root planing during pregnancy is associated with a reduction in the preterm birth rate.

Design: Systematic review and meta-analysis of randomised controlled trials.

Data Sources: Cochrane Central Trials Registry, ISI Web of Science, Medline, and reference lists of relevant studies to July 2010; hand searches in key journals.

Vaginal progesterone gel for luteal phase support in IVF/ICSI cycles: a meta-analysis.

Objective: To investigate whether vaginal progesterone gel may result in similar or higher pregnancy rates compared with all other vaginal progesterone forms when used for luteal-phase support.

Design: Meta-analysis of randomized controlled trials using odds ratios (OR) and 95% confidence intervals (CI).

Patient(s): Infertile women undergoing IVF or ICSI.

Aromatase inhibitors for female infertility: a systematic review of the literature.

Ovulation induction remains a milestone in the treatment of women with anovulatory infertility. Clomiphene citrate (CC) is considered the first line treatment for induction of ovulation in women with polycystic ovary syndrome (PCOS), while it may be used for ovulation induction in unexplained infertility. Aromatase inhibitors (AI) have been introduced as a new treatment option that could challenge CC for ovulation induction.
