Aims: The purpose of this study was to investigate correlations between first trimester placental volume (PV) and blood flow indexes (FIs), bilateral uterine artery pulsatility indexes, notching, and biochemical parameters: pregnancy-associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotropin (f-β-hCG), and insulin-like growth factor-1 (IGF-1) to predict the high-risk pregnancies in the first trimester.
Methods: We prospectively examined 310 patients at 11-14 weeks of pregnancy using transabdominal 3D gray scale and power Doppler ultrasound for assessing PV, vascularization index, FI, and vascularization FI (VFI). The acquired volumes were analyzed using VOCAL™ imaging software. The results were correlated with biochemical parameters.
Results: We found significant correlations between PV and biochemical parameters, and between placental blood flow studies and other parameters. Finally, PV/crown-rump length so called the placental quotient is also related to both PAPP-A and VFI.
Conclusions: Placental volumetry, uterine artery Doppler studies, blood flow calculations and biochemical parameters, such as f-β-hCG, PAPP-A, and IGF-1 could be important in the early and rapid diagnosis of high-risk pregnancies. Thus, they may be useful in first trimester prediction of fetal growth restriction presenting with alterations in PV and vascularity.

Background: Senility influences fertility in women and companion animals, especially horses.
Aim: This study aimed to investigate the effect of aging in horses on the daily changes in the dominant follicle (DF) dynamics and hemodynamics, antimüllerian hormone (AMH), enzymes, antioxidants, and ovarian hormones during the estrous cycle.
Methods: Ovaries of old mares ( = 5, age >20 years) and young native mares ( = 6, age <10 years) were scanned during 6 different estrous cycles from March 2022 to August 2023 with Doppler ultrasound.

Objective: To comparatively evaluate the effectiveness of uterine artery embolization (UAE), focused ultrasound (HIFU), radiofrequency ablation (RFT), and laparoscopic/laparotomic surgery in the conservative treatment of uterine fibroids DATA SOURCES: The research was performed via electronic databases PubMed, EMBASE, and Cochrane Library, using the PRISMA standards.
Methods Of Study Selection: The network included 10 randomized trials between 2000 and 2024 and 1002 randomized subjects.
Tabulation: The Network meta-analysis (NMA) was carried out with subroutine netmeta on R.

Antiphospholipid syndrome (APS) is associated with recurrent pregnancy morbidity, yet the underlying mechanisms remain elusive. We performed multifaceted characterization of the biological and transcriptomic signatures of mouse placenta and uterine natural killer (uNK) cells in APS. Histological analysis of APS placentas unveiled placental abnormalities, including disturbed angiogenesis, occasional necrotic areas, fibrin deposition, and nucleated red blood cell enrichment.

Introduction: The persistent sciatic artery (PSA) is a rare congenital vascular anomaly that arises when the embryonic axial artery fails to regress, potentially leading to serious complications such as limb ischemia.
Case Presentation: We report the case of a 47-year-old woman with a history of essential hypertension and recent hormonal treatment for uterine fibroids. She developed acute limb ischemia due to bilateral PSA thrombosis, which was confirmed through comprehensive imaging.

Objective: Polycystic ovary syndrome (PCOS) is an important factor contributing to infertility in reproductive-aged women. Hyperandrogenism (HA) plays an important role in the pathogenesis of PCOS. This study was conducted to explore the follicular development and endometrial receptivity of different androgen phenotypes in reproductive-aged patients with PCOS.
