Proposal for Diagnostic Criteria of Y-Shaped Dysmorphic Uterus Based on 3-Dimensional Transvaginal Ultrasound Measurements.

STUDY OBJECTIVE: To define objective and readily applied diagnostic criteria for Y-shaped uteri using 3-dimensional transvaginal ultrasound (3D-TVUS) volume recordings. DESIGN: A retrospective case-control diagnostic measurements study. SETTING: A tertiary university hospital's reproductive health and research center. PATIENTS: Two hundred thirteen patients who presented with infertility between January 2020 and December 2022. INTERVENTIONS: Two blinded physicians re-evaluated the 3D-TVUS images of all patients for the presence of a uterine abnormality. The images of patients with a Y-shaped uterus were re-evaluated, and descriptive measurements were done. MEASUREMENTS AND MAIN RESULTS: The most common uterine abnormality in this cohort was the Y-shaped uterus with a prevalence of 12.2%, followed by the arcuate, T-shaped, and septate uteri, respectively. Reviewers identified 26 and 28 Y-shaped uteri, respectively, and came to a consensus on 25 images. Diagnostic criteria for the Y-shaped uterus based on 3D-TVUS findings have been specified as: lateral indentation depths between 4 and 7 mm, fundal indentation depth between 5 and 9 mm, lateral indentation angles between 121° and 149°, fundal indentation angle between 121° and 145°, and Y-angles 25° to 46°. CONCLUSION: Some subtypes of dysmorphic uteri, such as the Y-shaped uterus, whose clinical significance is unknown and may be variants of the normal, may actually be more common than thought. Determining objective diagnostic criteria with 3D-TVUS will allow standard research on these anomalies and their clinical significance.

Effect of Antenatal Magnesium Sulfate Exposure on Patent Ductus Arteriosus in Premature Infants.

OBJECTIVE: Magnesium sulfate (MgSO4) provides effective fetal neuroprotection. However, there is conflicting evidence regarding the association between antenatal MgSO4 exposure and patent ductus arteriosus (PDA). Thus, herein, we aimed to evaluate the association between antenatal MgSO4 exposure and PDA. STUDY DESIGN: Preterm infants born between 240/7 and 316/7 weeks of gestation were included in this retrospective study. Infants who died within the first 72 hours of life and those with significant congenital anomalies were excluded from the study. Echocardiographic and clinical assessment parameters were used to define PDA and hemodynamically significant PDA (hsPDA). Treatments were planned according to the standard protocols of the unit. The following data were collected from hospital medical records: perinatal characteristics, neonatal outcomes, detailed PDA follow-up findings, and maternal characteristics including MgSO4 exposure and doses. RESULTS: Of the 300 included infants, 98 (32.6%) were exposed to antenatal MgSO4. hsPDA rates were similar in the infants exposed and not exposed to antenatal MgSO4, when adjusted for antenatal steroid administration, gestational age, and birth weight (OR: 1.6, 95% CI: 0.849-3.118, p = 0.146). The rates of PDA ligation and open PDA at discharge were similar between the groups. A cumulative MgSO4 dose of >20 g was associated with an increased risk of hsPDA (crude OR: 2.476, 95% CI: 0.893-6.864, p = 0.076; adjusted OR: 3.829, 95% CI: 1.068-13.728, p = 0.039). However, the cumulative dose had no effect on the rates of PDA ligation or open PDA at discharge. Rates of prematurity-related morbidities and mortality were similar between the groups. CONCLUSION: Although antenatal MgSO4 exposure may increase the incidence of hsPDA, it may not affect the rates of PDA ligation or open PDA at discharge. Further studies are required to better evaluate the dose-dependent outcomes and identify the MgSO4 dose that not only provides neuroprotection but also has the lowest risk of adverse effects. KEY POINTS: · Antenatal exposure of MgSO4 may cause PDA.. · Antenatal MgSO4 exposure may not increase the rates of PDA ligation or open PDA at discharge.. · Further studies are required to better evaluate the dose-dependent outcomes and optimal MgSO4 dose..

Recurrence of Uterine Fibroids After Conservative Surgery or Radiological Procedures: a Narrative Review.

The present narrative review aims to discuss the available data on the incidence and the risk factors of uterine fibroids (UFs) recurrence after different types of conservative surgical or radiologic procedures in women wishing to preserve their uterus. UFs are the most common benign tumors in women all over the world. Clinical presentation, including abnormal uterine bleeding (AUB), pelvic pain, bulky symptoms, and infertility affect patients' quality of life, and a large variety of conservative treatments are available especially for those with desire of pregnancy. Fertility sparing surgery, by either laparoscopy, hysteroscopy or laparotomy, or radiological interventions (uterine artery embolization, high-intensity focused ultrasound or magnetic resonance-guided focused ultrasound), are the most common therapeutic approaches. However, the genetic or acquired predisposition to UFs remain despite the treatments, and the recurrences are frequently described in a large percentage of patients. The most relevant risk factors for recurrence of UFs are young age at the first surgery, incomplete fibroid resection, the presence of multiple lesions, an enlarged uterus, and the coexistence with other pelvic diseases. The discussion on the possible medical strategy to reduce the recurrence is an open field of clinical investigation, in particular by using hormonal drugs.

Random start ovarian stimulation before gonadotoxic therapies in women with cancer: a systematic review and meta-analysis.

The aim of this systematic review and meta-analysis was to quantify the effect of random start ovarian stimulation (RSOS) compared with conventional start ovarian stimulation (CSOS) in cancer patients before gonadotoxic treatment. The final analytical cohort encompassed 688 RSOS and 1076 CSOS cycles of cancer patients before gonadotoxic treatment. Eleven studies were identified by database searches of MEDLINE, Cochrane Library and cited references. The primary outcomes of interest were the number of oocytes and mature oocytes collected, the number of embryos cryopreserved and the metaphase II (MII)-antral follicle count (AFC) ratio. The studies were rated from medium to high quality (from 6 to 9) according to the Newcastle-Ottawa Quality Assessment Scale. The two protocols resulted in similar numbers of oocytes collected, MII oocytes, embryos available for cryopreservation and comparable MII-AFC and fertilization rates. The duration of ovarian stimulation was longer (standardized mean difference [SMD] 0.35, 95% CI 0.09 to 0.61; P = 0.009) and gonadotrophin consumption was higher (SMD 0.23, 95% CI 0.06 to 0.40; P = 0.009) in RSOS compared with CSOS. This systematic review and meta-analysis show that the duration of stimulation is longer, and the total gonadotrophin consumption is higher in cancer patients undergoing RSOS compared with those undergoing CSOS, with no significant effect on mature oocyte yield.

Investigation of the risk factors associated with osteoporosis in postmenopausal women

Objective: Osteoporosis is a substantial global public health issue. The objective of this study was to evaluate the risk variables associated with osteoporosis among patients seeking care at an outpatient menopausal clinic in a tertiary university hospital. Material and Methods: In this retrospective, cross-sectional study postmenopausal women who attended the outpatient menopause clinic of Baskent University Hospital between June 01, 2014, and August 31, 2015, were enrolled. Patients' datasheets were reviewed and data including age, body mass index, parity, duration and age of menopause, history of smoking and oral contraceptive pills (OCPs) use, natural or surgical menopause, and calcium-containing food consumption were collected through a standardized questionnaire. Bone mineral density (BMD) was measured at the femur neck and lumbar spine by dual energy X-ray absorptiometry. Results: A total of 1,148 women with a mean age of 53.5±6.7 years, mean duration of menopause 7.1±6.2 years and mean age of menopause 46.3±5.1 years were identified. Of these, 235 (20.5%) were diagnosed as having osteoporosis. The average femur and lumbar T-values showed a decrease in normal weight patients compared to overweight, obese, and morbidly obese patients (F=22,337, p<0.001 and F=50,195, p<0.001, respectively). The mean femur T-values were higher in participants who used OCPs, regularly consumed a calcium-rich diet, and performed regular physical activity (p<0.05, p<0.01 and p<0.05). Positive correlations were noted between giving birth and femur T-values (r=0.065, p=0.027), between natural menopause and lumbar T-values (r=0.060, p=0.043), and between consuming a calcium-rich diet and femur T-values (r=0.087, p=0.003 and r=0.064, p=0.031, respectively). Conclusion: Using OCPs, lifelong physical activity, and a healthy diet rich in calcium are important factors for the prevention of low lumbar spine and femoral BMD and by implication, osteoporosis.

A promising treatment for spontaneous ovarian hyperstimulation syndrome due to familial partial lipodystrophy: GnRH analogs combined with cyst aspiration.

PURPOSE: To present a patient with familial partial lipodystrophy (FPLD) and polycystic ovary syndrome (PCOS) who was admitted with spontaneous ovarian hyperstimulation syndrome (OHSS)-like extremely enlarged ovaries, which was successfully treated using gonadotropin-releasing hormone analogs and abdominal cyst aspiration in combination. METHOD: This is a descriptive case report of a single patient with FPLD and PCOS. RESULTS: Clinical improvement was achieved 6 months after therapy besides progressive reduction in total testosterone and DHEAS. Furthermore, there was a significant improvement in hyperinsulinemia and hypertriglyceridemia. Additionally, reduction in the size of ovarian cysts, reduction in the size and number of localizations of acanthosis nigricans, reduction in scores of mFGS, and weight loss were also observed. CONCLUSION: Although there are few reports in the literature describing the association between PCOS with FPLD, management of this novel spontaneous OHSS-like condition has not yet been clearly defined. In the case of extremely enlarged multicystic ovaries and severe hyperandrogenemia, GnRH analogs may be considered to prevent ovarian enlargement and reduce hyperandrogenemia, especially when other treatment options are inappropriate.

Presence of Endometrioma Does Not Impair Embryo Quality and Assisted Reproductive Technology (ART) Cycle Outcome in Diminished Ovarian Reserve (DOR) Patients.

This study aims to assess the impact of endometrioma on embryo quality and cycle outcome in patients who undergo assisted reproductive technology (ART) treatment due to diminished ovarian reserve (DOR). Retrospective case-control study was conducted in women ≤ 40 years of age who underwent ART treatment caused by DOR, defined according to POSEIDON criteria, at a university-based infertility clinic between January 2015 and December 2020. Three groups of patients were selected: group A included patients with an idiopathic DOR, group B included patients with endometrioma(s) who underwent ovarian cystectomy, and group C included patients with endometrioma(s) without surgical treatment. A total of 351 women with DOR were included in the final analysis. Demographic characteristics, including age and AMH, were similar between the groups. Significant differences were observed among groups on mean number of MII oocytes retrieved (1.88 ± 1.59 vs. 2.84 ± 2.89 vs. 2.78 ± 2.41, respectively; p < 0.001) and mean number of embryos (1.04 ± 1.18 vs. 1.87 ± 2.01 vs. 1.66 ± 1.81, respectively; p < 0.001). However, the mean number of top-quality embryos, cycle cancellation, and live birth rates were similar between the groups. Clinical pregnancy (35 (26.5%) vs. 8 (18.2%) vs. 18 (42.9%), respectively; p = 0.038) and miscarriage rates (12 (9.1%) vs. 0 vs. 8 (19.0%), respectively; p = 0.009) were higher in endometrioma group without surgery. Women with DOR appear to have similar ART cycle outcomes regardless of the etiology, in terms of live birth rates. Infertility of endometrioma patients might be related to altered endometrium rather than to decreased oocyte quality. Cystectomy for endometrioma before IVF did not seem to affect the LBR.

Long-term outcomes of fetal posterior fossa abnormalities diagnosed with fetal magnetic resonance imaging

Objective: The diagnosis of posterior fossa abnormalities (PFA) in the intrauterine period and association with pregnancy outcomes are still controversial. PFA is generally referred to maternal-fetal medicine specialists. The primary purpose of PFA diagnosis is to screen for other accompanying abnormalities, provide prognostic information to families, and discuss the termination option. Material and Methods: This retrospective study was conducted in patients diagnosed with PFA between January 2013 and September 2020 in a tertiary perinatology clinic. All patients underwent routine second-trimester ultrasound screening and definitive diagnosis was made by fetal magnetic resonance imaging (MRI) in the presence of a suspected anomaly. Results: There were 164 fetal MRIs for fetal abnormalities during the study period and 22 (13.4%) were diagnosed with a PFA on fetal MRI. Indications for fetal MRI included four (18%) with Mega Cisterna Magna, two (9.1%) with rhomboencephalosynapsis, and thirteen (59.1%) with Vermian Hypoplasia-Dandy-Walker variant. Two patients, with neural tube defects and lumbosacral neural-tube defect are still alive. However, iniencephaly was detected in last patient who died in the postnatal period. Conclusion: Diagnosis of PFA abnormalities is complex, and the prognosis in PFA is often unclear. The prognosis is not affected by maternal and fetal factors and allows the recognition of additional accompanying abnormalities. Fetal MRI is an imaging method that can provide retrospective examination and research, especially in pregnancies with poor prognoses.

Impact of an estrogen replacement regimen on live birth rate in frozen-thawed good-quality embryo transfer.

OBJECTIVE: To assess the impact of an estrogen replacement regimen on frozen embryo transfer (FET) cycle outcome. METHODS: In the present retrospective cohort study, data of infertile women undergoing FET with good-quality embryos were reviewed. The first group received 2 mg of estradiol hemihydrate (EH) once daily for 6 to 7 days, then twice daily for 4 to 5 days, and then three times a day until embryo transfer. The second group received EH twice daily for 7 to 8 days, then three times a day. The third group received EH three times a day constantly. The main outcome measure was live birth rate. RESULTS: In total, 394 FET cycles were included. The fixed 6-mg group required the highest estradiol hemihydrate dose. The duration of estrogen treatment was significantly longer in the first group. Maximal endometrial thickness was highest in the second group (10.2 ± 1.3 mm vs. 9.6 ± 1.4 mm vs. 8.6 ± 0.9 mm, respectively; P < 0.001). The clinical pregnancy rates in the groups were 41.1%, 55.2%, and 42.2%, respectively (P = 0.035). Live birth rates were 40.8%, 50.9%, and 48.1%, respectively (P = 0.320). CONCLUSION: In FET cycles with hormone replacement therapy, a step-up 4-mg regimen provides thicker endometrium with optimal-dose estrogen in an adequate time frame. The tendency for increased clinical pregnancy and live birth rates is remarkable.
