Perinatal outcome of pregnancies caused by assisted reproduction technique (ART) is substantially worse when compared with pregnancies following natural conception. We investigated the possible risks of non-IVF ART on perinatal health. We conducted a retrospective cohort study with two exposure groups: a study group of pregnancies after controlled ovarian stimulation (COS), with or without arti...

We have observed that the elevated plasma adenosine levels are associated with hyperuricemia in nonpreeclamptic twin pregnancies. In animal models, extracellular adenosine is taken up by cells to form adenine nucleotides or is degraded to other purine metabolites such as hypoxanthine, which is further metabolized to xanthine and uric acid. In this study, we measured plasma hypoxanthine levels t...

BACKGROUND Prenatal screening and diagnosis of chromosomal abnormalities especially Down's syndrome in IVF pregnancies are complicated by higher maternal age, a high multiple pregnancy rate, a high risk of a vanishing twin and an increased risk of chromosomal abnormalities, particularly in pregnancies after ICSI. The aim of the present systematic review was to evaluate the findings of first tri...

Objective: To present the reference range of fetal thymus gland according to gestational age groups. Methods: In this prospective study, size was assessed in singleton, uncomplicated pregnancies between 19 and 38 weeks gestation our outpatient clinic 2019 2020. Based on their monthly pregnancy follow-ups, measurement divided into 5 groups (Group 1: 19–22 weeks, Group 2: 23–26 3: 27–30 4: 31–34 ...

INTRODUCTION Chorangiomas (CAs) are the most common non-trophoblastic tumor-like-lesions of the placenta. Although the clinical significance of small CAs is unknown, the large lesions are often associated with maternal and fetal complications. The aim of our study was to assess the maternal clinical characteristics and neonatal outcome in singleton and multiple pregnancies with placental CA. ...

BACKGROUND Information about the recurrence of spontaneous preterm birth in subsequent twin/singleton pregnancies is scattered. OBJECTIVES To quantify the risk of recurrence of spontaneous preterm birth in different subtypes of subsequent pregnancies. SEARCH STRATEGY An electronic literature search in OVID MEDLINE and EMBASE, complemented by PubMed, to find recent studies. SELECTION CRITE...

INTRODUCTION Triplet and higher-order multiple pregnancies are well known to be associated with increased adverse outcomes. This study reviewed the perinatal outcomes in women with a triplet pregnancy who underwent fetal reduction versus expectant management at a university hospital in Hong Kong. METHODS This was a retrospective review of triplet pregnancies at Prince of Wales Hospital in Hon...
