RESUMEN
Importance: Placenta accreta spectrum (PAS) represents a range of disorders characterized by abnormal placental invasion and is associated with severe maternal morbidity and mortality. Objective: The aim of this study was to review and compare the most recently published major guidelines on the diagnosis and management of this potentially life-threatening obstetric complication. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, the International Society for Abnormally Invasive Placenta, the Royal College of Obstetricians and Gynecologists, the International Federation of Gynecology and Obstetrics, and the Society of Obstetricians and Gynecologists of Canada on PAS disorders was carried out. Results: There is a consensus among the reviewed guidelines regarding the definition and the diagnosis of PAS using specific sonographic signs. In addition, they all agree that the use of magnetic resonance imaging should be limited to the evaluation of the extension to pelvic organs in case of placenta percreta. Moreover, American College of Obstetricians and Gynecologists, Royal College of Obstetricians and Gynecologists, International Federation of Gynecology and Obstetrics, and the Society of Obstetricians and Gynecologists of Canada agree that screening for PAS disorders should be based on clinical risk factors along with sonographic findings. Regarding management, they all highlight the importance of a multidisciplinary team approach and recommend delivery by elective cesarean section at a tertiary center with experienced staff and appropriate resources. Routine preoperative ureteric stenting and occlusion of pelvic arteries are universally not recommended. Moreover, hysterectomy following the delivery of the fetus, expectant management with placenta left in situ, and conservative management in case of focal disease and desired fertility are all considered as acceptable treatment options. The reviewed guidelines also suggest some measures for intraoperative and postoperative hemorrhage control and recommend prophylactic administration of antibiotics. Methotrexate after expectant management is unanimously discouraged. On the other hand, there is no common pathway with regard to the optimal timing of delivery, the recommended mode of anesthesia, the preferred skin incision, and the effectiveness of the delayed hysterectomy approach. Conclusions: PAS disorders are mainly iatrogenic conditions with a constantly rising incidence and potentially devastating consequences for both the mother and the neonate. Thus, the development of uniform international practice protocols for effective screening, diagnosis, and management seems of paramount importance and will hopefully drive favorable pregnancy outcomes.

Background and Objectives: Neonates born from thawed embryo transfers tend to have a significantly higher birthweight compared to those from fresh embryo transfers. The aim of this study was to compare the crown-rump length (CRL) between thawed and fresh embryos to investigate the potential causes of different growth patterns between them. Materials and Methods: This was a retrospective study (July 2010-December 2023) conducted at the Third Department of Obstetrics and Gynecology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Greece. In total, 3082 assisted reproductive technology (ART) pregnancies (4044 embryos) underwent a routine scan at 11+0-13+6 gestational weeks and were included in the study. Maternal age, the type of embryo transfer (thawed vs. fresh, donor vs. their own oocytes), CRL, twin and singleton gestations were analyzed. Results: The mean maternal age in thawed was significantly higher than in fresh embryos (39.8 vs. 35.8 years, p-value < 0.001). The mean CRL z-score was significantly higher in thawed compared to fresh embryo transfers (0.309 vs. 0.199, p-value < 0.001). A subgroup analysis on singleton gestations showed that the mean CRL z-score was higher in thawed blastocysts compared to fresh (0.327 vs. 0.215, p-value < 0.001). Accordingly, an analysis on twins revealed that the mean CRL z-score was higher in thawed blastocysts (0.285 vs. 0.184, p-value: 0.015) and in oocytes' recipients compared to own oocytes' cases (0.431 vs. 0.191, p-value: 0.002). Conclusions: The difference in CRL measurements between thawed and fresh embryos may be a first indication of the subsequent difference in sonographically estimated fetal weight and birthweight. This finding highlights the need for additional research into the underlying causes, including maternal factors and the culture media used.
RESUMEN
Importance: Antenatal care plays a crucial role in safely monitoring and ensuring the well-being of both the mother and the fetus during pregnancy, ultimately leading to the best possible perinatal outcomes. Objective: The aim of this study was to review and compare the most recently published guidelines on antenatal care. Evidence Acquisition: A descriptive review of guidelines from the National Institute for Health and Care Excellence, the Public Health Agency of Canada, the World Health Organization, and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists regarding antenatal care was conducted. Results: There is a consensus among the reviewed guidelines regarding the necessary appointments during the antenatal period, the proper timing for induction of labor, the number and frequency of laboratory examinations for the assessment of mother's well-being, and management strategies for common physiological problems during pregnancy, such as nausea and vomiting, heartburn, pelvic pain, leg cramps, and symptomatic vaginal discharge. In addition, special consideration should be given for mental health issues and timely referral to a specialist, reassurance of complete maternal vaccination, counseling for safe use of medical agents, and advice for cessation of substance, alcohol, and tobacco use during pregnancy. Controversy surrounds clinical evaluation during the antenatal period, particularly when it comes to the routine use of an oral glucose tolerance test and symphysis-fundal height measurement for assessing fetal growth, whereas routine cardiotocography and fetal movement counting are suggested practices only by Royal Australian and New Zealand College of Obstetricians and Gynaecologists. Of note, recommendations on nutritional interventions and supplementation are offered only by Public Health Agency of Canada and World Health Organization, with some minor discrepancies in the optimal dosage. Conclusions: Antenatal care remains a critical factor in achieving positive outcomes, but there are variations depending on the socioeconomic status of each country. Therefore, the establishment of consistent international protocols for optimal antenatal care is of utmost importance. This can help provide safe guidance for healthcare providers and, consequently, improve both maternal and fetal outcomes.

Importance: Macrosomia represents the most significant risk factor of shoulder dystocia (SD), which is a severe and emergent complication of vaginal delivery. They are both associated with adverse pregnancy outcomes. Objective: The aim of this study was to review and compare the most recently published influential guidelines on the diagnosis and management of fetal macrosomia and SD. Evidence Acquisition: A comparative review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Royal College of Obstetricians and Gynaecologists, the National Institute for Health and Care Excellence, the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG), and the Department for Health and Wellbeing of the Government of South Australia on macrosomia and SD was conducted. Results: The ACOG and RANZCOG agree that macrosomia should be defined as birthweight above 4000-4500 g regardless of the gestational age, whereas the National Institute for Health and Care Excellence defines macrosomia as an estimated fetal weight above the 95th percentile. According to ACOG and RANZCOG, ultrasound scans and clinical estimates can be used to rule out fetal macrosomia, although lacking accuracy. Routine induction of labor before 39 weeks of gestation with the sole indication of suspected fetal macrosomia is unanimously not recommended, but an individualized counseling should be provided. Exercise, appropriate diet, and prepregnancy bariatric surgery are mentioned as preventive measures. There is also consensus among the reviewed guidelines regarding the definition and the diagnosis of SD, with the "turtle sign" being the most common sign for its recognition as well as the poor predictability of the reported risk factors. Moreover, there is an overall agreement on the algorithm of SD management with McRoberts technique suggested as first-line maneuver. In addition, appropriate staff training, thorough documentation, and time keeping are crucial aspects of SD management according to all medical societies. Elective delivery for the prevention of SD is discouraged by all the reviewed guidelines. Conclusions: Macrosomia is associated not only with SD but also with maternal and neonatal complications. Similarly, SD can lead to permanent neurologic sequalae, as well as perinatal death if managed in a suboptimal way. Therefore, it is crucial to develop consistent international practice protocols for their prompt diagnosis and effective management in order to safely guide clinical practice and improve pregnancy outcomes.

Importance: Postnatal care refers to the ongoing health care provision of both the mother and her offspring and contributes to the timely identification and effective management of complications in the postpartum period, to secure maternal and infant short- and long-term well-being. Objective: The aim of this study was to review and compare the most recently published influential guidelines on postnatal care practices. Evidence Acquisition: A comparative review of guidelines from the American College of Obstetricians and Gynecologists, the World Health Organization, the National Institute for Health and Care Excellence, and the Public Health Agency of Canada regarding postnatal care was conducted. Results: There is a consensus among the reviewed guidelines regarding the importance of health care provision in the postpartum period, including home visits and midwifery services, the use of telemedicine for the facilitation of communication with the patient, and the appropriate preparation for discharge, as well as the discharge criteria. All medical societies also agree on the clinical aspects that should be evaluated at each postnatal visit, although discrepancies exist with regard to the contact schedule. In addition, there is consistency regarding the management of postpartum infections, perineal pain, fecal and urinary incontinence, and physical activity guidance. Mental health issues should be addressed at each postnatal visit, according to all guidelines, but there is disagreement regarding routine screening for depression. As for the optimal interpregnancy interval, the American College of Obstetricians and Gynecologists recommends avoiding pregnancy for at least 6 months postpartum, whereas the National Institute for Health and Care Excellence recommends a 12-month interval. There is no common pathway regarding the recommended contraceptive methods, the nutrition guidance, and the postpartum management of pregnancy complications. Of note, the World Health Organization alone provides recommendations concerning the prevention of specific infections during the postnatal period. Conclusions: Postnatal care remains a relatively underserved aspect of maternity care, although the puerperium is a critical period for the establishment of motherhood and the transition to primary care. Thus, the development of consistent international protocols for the optimal care and support of women during the postnatal period seems of insurmountable importance to safely guide clinical practice and subsequently reduce maternal and neonatal morbidity.

BACKGROUND AND OBJECTIVES: Accurate diagnosis of labor progress is crucial for making well-informed decisions regarding timely and appropriate interventions to optimize outcomes for both the mother and the fetus. The aim of this study was to assess the progress of the second stage of labor using intrapartum ultrasound. MATERIAL AND METHODS: This was a prospective study (December 2022-December 2023) conducted at the Third Department of Obstetrics and Gynecology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Greece. Maternal-fetal and labor characteristics were recorded, and two ultrasound parameters were measured: the angle of progression (AoP) and the head-perineum distance (HPD). The correlation between the two ultrasonographic values and the maternal-fetal characteristics was investigated. Multinomial regression analysis was also conducted to investigate any potential predictors of the mode of delivery. RESULTS: A total of 82 women at the second stage of labor were clinically and sonographically assessed. The mean duration of the second stage of labor differed between vaginal and cesarean deliveries (65.3 vs. 160 min; p-value < 0.001) and between cesarean and operative vaginal deliveries (160 vs. 88.6 min; p-value = 0.015). The occiput anterior position was associated with an increased likelihood of vaginal delivery (OR: 24.167; 95% CI: 3.8-152.5; p-value < 0.001). No significant differences were identified in the AoP among the three different modes of delivery (vaginal: 145.7° vs. operative vaginal: 139.9° vs. cesarean: 132.1°; p-value = 0.289). The mean HPD differed significantly between vaginal and cesarean deliveries (28.6 vs. 41.4 mm; p-value < 0.001) and between cesarean and operative vaginal deliveries (41.4 vs. 26.9 mm; p-value = 0.002); it was correlated significantly with maternal BMI (r = 0.268; p-value = 0.024) and the duration of the second stage of labor (r = 0.256; p-value = 0.031). Low parity (OR: 12.024; 95% CI: 6.320-22.876; p-value < 0.001) and high HPD (OR: 1.23; 95% CI: 1.05-1.43; p-value = 0.007) were found to be significant predictors of cesarean delivery. CONCLUSIONS: The use of intrapartum ultrasound as an adjunctive technique to the standard clinical evaluation may enhance the diagnostic approach to an abnormal labor progress and predict the need for operative vaginal or cesarean delivery.
RESUMEN
Importance: Several medications have been used to achieve medical abortion in the first trimester of pregnancy. The most commonly used is the combination of mifepristone and misoprostol; however, different doses and routes of administration have been proposed. Objective: The aim of this study was to summarize published data on the effectiveness, adverse effects, and acceptability of the various combinations of mifepristone and misoprostol in medical abortion protocols in the first trimester of pregnancy. Evidence Acquisition: This was a comprehensive review, synthesizing the findings of the literature on the current use of mifepristone and misoprostol for first-trimester abortion. Results: The combination of mifepristone and misoprostol seems to be more effective than misoprostol alone. Regarding the dosages and routes, mifepristone is administered orally, and the optimal dose is 200 mg. The route of administration of misoprostol varies; the sublingual and buccal routes are more effective; however, the vaginal route (800 µg) is associated with fewer adverse effects. Finally, the acceptability rates did not differ significantly. Conclusions: Different schemes for first-trimester medical abortion have been described so far. Future research needs to focus on identifying the method that offers the best trade-off between efficacy and safety in first-trimester medical abortion.

Importance: Fetal growth restriction (FGR) is a common pregnancy complication and a significant contributor of fetal and neonatal morbidity and mortality, mainly due to the lack of effective screening, prevention, and management policies. Objective: The aim of this study was to review and compare the most recently published influential guidelines on the management of pregnancies complicated by FGR. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Society for Maternal-Fetal Medicine, the International Federation of Gynecology and Obstetrics, the International Society of Ultrasound in Obstetrics and Gynecology, the Royal College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada (SOGC), the Perinatal Society of Australia and New Zealand, the Royal College of Physicians of Ireland, the French College of Gynecologists and Obstetricians (FCGO), and the German Society of Gynecology and Obstetrics on FGR was carried out. Results: Several discrepancies were identified regarding the definition of FGR and small-for-gestational-age fetuses, the diagnostic criteria, and the need of testing for congenital infections. On the contrary, there is an overall agreement among the reviewed guidelines regarding the importance of early universal risk stratification for FGR to accordingly modify the surveillance protocols. Low-risk pregnancies should unanimously be evaluated by serial symphysis fundal height measurement, whereas the high-risk ones warrant increased sonographic surveillance. Following FGR diagnosis, all medical societies agree that umbilical artery Doppler assessment is required to further guide management, whereas amniotic fluid volume evaluation is also recommended by the ACOG, the SOGC, the Perinatal Society of Australia and New Zealand, the FCGO, and the German Society of Gynecology and Obstetrics. In case of early, severe FGR or FGR accompanied by structural abnormalities, the ACOG, the Society for Maternal-Fetal Medicine, the International Federation of Gynecology and Obstetrics, the Royal College of Obstetricians and Gynecologists, the SOGC, and the FCGO support the performance of prenatal diagnostic testing. Consistent protocols also exist on the optimal timing and mode of delivery, the importance of continuous fetal heart rate monitoring during labor, and the need for histopathological examination of the placenta after delivery. On the other hand, guidelines concerning the frequency of fetal growth and Doppler velocimetry evaluation lack uniformity, although most of the reviewed medical societies recommend an average interval of 2 weeks, reduced to weekly or less when umbilical artery abnormalities are detected. Moreover, there is a discrepancy on the appropriate timing for corticosteroids and magnesium sulfate administration, as well as the administration of aspirin as a preventive measure. Cessation of smoking, alcohol consumption, and illicit drug use are proposed as preventive measures to reduce the incidence of FGR. Conclusions: Fetal growth restriction is a clinical entity associated with numerous adverse antenatal and postnatal events, but currently, it has no definitive cure apart from delivery. Thus, the development of uniform international protocols for the early recognition, the adequate surveillance, and the optimal management of growth-restricted fetuses seem of paramount importance to safely guide clinical practice, thereby improving perinatal outcomes of such pregnancies.

Importance: Group B Streptococcus (GBS) colonization during pregnancy is associated with significant neonatal morbidity and mortality and represents a major public health concern, often associated with poor screening and management. Objective: The aim of this study was to review and compare the most recently published influential guidelines on the screening and management of this clinical entity during antenatal and intrapartum periods. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists, the Royal College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, and the Society of Obstetricians and Gynecologists of Canada on the prevention of early-onset neonatal group B streptococcal disease was carried out. Results: There is a consensus among the reviewed guidelines regarding the optimal screening specimen type, indications for intrapartum antibiotic administration such as bacteriuria during pregnancy, clinical signs of chorioamnionitis or maternal pyrexia, and history of GBS-related neonatal disease. There is also agreement on several conditions where no intervention is recommended, that is, antepartum treatment of GBS and GBS-positive women with planned cesarean delivery and intact membranes. Controversy exists regarding the optimal screening time, with the Royal College of Obstetricians and Gynecologists stating against routine screening and on management strategies related to preterm labor and preterm prelabor rupture of membranes. Conclusions: The development of consistent international practice protocols for the timely screening of GBS and effective management of this clinical entity both during pregnancy and the intrapartum period seems of paramount importance to safely guide clinical practice and subsequently improve neonatal outcomes.

Importance: Osteoporosis causes increased morbidity and mortality, and thus poses a significant economic burden to the health systems worldwide. Objective: The aim of this study was to review and compare the most recently published major guidelines on diagnosis and management of this common medical entity. Evidence Acquisition: A thorough comparative review of the most influential guidelines from the RACGP (Royal Australian College of General Practitioners), the ESCEO-IOF (European Society for Clinical and Economic Aspects of Osteoporosis-International Osteoporosis Foundation), the NOGG (National Osteoporosis Guideline Group), the NAMS (North American Menopause Society), the ES (Endocrine Society), and the ACOG (American College of Obstetricians and Gynecologists) was conducted. Results: The reviewed guidelines generally agree on the definition, the criteria, and investigations used to diagnose osteoporosis. They also concur regarding the risk factors for osteoporosis and the suggested lifestyle modifications (calcium and vitamin D intake, normal body weight, reduction of alcohol consumption, and smoking cessation). However, there is lack of consensus on indications for fracture risk assessment in the general population and the exact indications for bone mineral density assessment. Referral to a bone specialist is reserved for complex cases of osteoporosis (NOGG, NAMS, and ACOG) or in case of inadequate access to care (RACGP). The use of hip protectors to reduce the risk of fractures is supported by RACGP, NOGG, and NAMS, solely for high-risk elderly patients in residential care settings. All guidelines reviewed recognize the efficacy of the pharmacologic agents (ie, bisphosphonates, denosumab, hormone therapy, and parathyroid hormone analogs). Nonetheless, recommendations regarding monitoring of pharmacotherapy differ, primarily in the case of bisphosphonates. The proposed intervals of repeat bone mineral density testing after initiation of drug therapy are set at 2 years (RACGP), 1-3 years (NAMS, ES, and ACOG), or 3-5 years (ESCEO-IOF and NOGG). All guidelines agree upon the restricted use of bone turnover markers only in bone specialist centers for treatment monitoring purposes. Finally, the definition of treatment failure varies among the reviewed guidelines. Conclusions: Osteoporosis is a distressing condition for women, mainly those of postmenopausal age. Thus, it seems of paramount importance to develop consistent international practice protocols for more cost-effective diagnostic and management techniques, in order to improve women's quality of life.

Importance: Cervical cerclage (CC) represents one of the few effective measures currently available for the prevention of preterm delivery caused by cervical insufficiency, thus contributing in the reduction of neonatal morbidity and mortality rates. Objective: The aim of this study was to review and compare the most recently published major guidelines on the indications, contraindications, techniques, and timing of placing and removal of CC. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Royal College of Obstetricians and Gynaecologists (RCOG), the Society of Obstetricians and Gynaecologists of Canada (SOGC), and the International Federation of Gynecology and Obstetrics (FIGO) on CC was carried out. Results: There is a consensus among the reviewed guidelines regarding the recommended techniques, the indications for rescue CC, the contraindications, as well as the optimal timing of CC placement and removal. All medical societies also agree that ultrasound-indicated CC is justified in women with history of prior spontaneous PTD or mid-trimester miscarriage and a short cervical length detected on ultrasound. In addition, after CC, serial sonographic measurement of the cervical length, bed rest, and routine use of antibiotics, tocolysis, and progesterone are unanimously discouraged. In case of established preterm labor, CC should be removed, according to ACOG, RCOG, and SOGC. Furthermore, RCOG and SOGC agree on the prerequisites that should be met before attempting CC. These 2 guidelines along with FIGO recommend history-indicated CC for women with 3 or more previous preterm deliveries and/or second trimester pregnancy miscarriages, whereas the ACOG suggests the use of CC in singleton pregnancies with 1 or more previous second trimester miscarriages related to painless cervical dilation or prior CC due to painless cervical dilation in the second trimester. The role of amniocentesis in ruling out intra-amniotic infection before rescue CC remains a matter of debate. Conclusions: Cervical cerclage is an obstetric intervention used to prevent miscarriage and preterm delivery in women considered as high-risk for these common pregnancy complications. The development of universal international practice protocols for the placement of CC seems of paramount importance and will hopefully improve the outcomes of such pregnancies.

Objective: Endometrial scratching (ES) during hysteroscopy before embryotransfer (ET) remains doubtable on whether it benefits the reproductive outcomes. The optimal technique is not clear and repeated implantation failure as a challenging field in in vitro fertilization (IVF) seems to be the springboard for clinicians to test its effectiveness. Methods: Medline, PMC, ScienceDirect, Scopus, CENTRAL, Google Scholar were searched from their inception up to April 2023 for studies to evaluate the effectiveness of adding endometrial scratching during hysteroscopy before ET. Results: The initial search yielded 959 references, while 12 eligible studies were included in the analyses, involving 2,213 patients. We found that hysteroscopy and concurrent ES before ET resulted in a statistically significant improvement in clinical pregnancy rate (CPR) [RR = 1.50, (95% CI 1.30-1.74), p < 0.0001] and live birth rate (LBR) [RR = 1.67, (95% CI 1.30-2.15), p < 0.0001] with no statistically significant difference on miscarriage rate [RR = 0.80 (95% CI 0.52-1.22), p = 0.30]. Conclusion: Our meta-analysis suggests that hysteroscopy with concurrent ES may be offered in IVF before ET as a potentially improving manipulation. Future randomized trials comparing different patient groups would also provide more precise data on that issue, to clarify specific criteria in the selection of patients. Systematic Review Registration: PROSPERO (CRD42023414117).

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare but serious condition. The first-line antenatal management of FNAIT consists of weekly IVIG with or without corticosteroids, ideally starting before 16 weeks of gestation.
RESUMEN
OBJECTIVES: To investigate the incidence and risk factors of bilobate placenta, as well as to assess its impact on preeclampsia (PE), preterm delivery (PTD) and small-for-gestational age (SGA) neonates. METHODS: A prospective study of singleton pregnancies, undergoing routine anomaly scan at 20+0-23+6 gestational weeks, was conducted, between 2018 and 2022. The impact of prenatally diagnosed bilobate placenta on PE, PTD and SGA was assessed. Multivariate logistic regression models were employed to assess the independent association between bilobate placenta and the main pregnancy outcomes, using specific confounders. Additionally, a risk factor analysis was performed. RESULTS: The study population included 6,454 pregnancies; the incidence of prenatally diagnosed bilobate placenta was 2.0â¯% (n=129). Bilobate placenta was associated with PE (aOR: 1.721; 95â¯% CI: 1.014-2.922), while no statistically significant association was found between this anatomical variation and SGA (aOR: 1.059; 95â¯% CI: 0.665-1.686) or PTD (aOR: 1.317; 95â¯% CI: 0.773-2.246). Furthermore, pregnancies with prenatally diagnosed bilobate placenta had an increased prevalence of abnormal cord insertion (marginal or velamentous) (9.8 vs. 27.1â¯%; p<0.001) and increased mean UtA PI z-score (0.03 vs. 0.23; p=0.039). Conception via ART (aOR: 3.669; 95â¯% CI: 2.248-5.989), previous history of 1st trimester miscarriage (aOR: 1.814; 95â¯% CI: 1.218-2.700) and advancing maternal age (aOR: 1.069; 95â¯% CI: 1.031-1.110) were identified as major risk factors for bilobate placenta. CONCLUSIONS: Bilobate placenta, excluding cases of co-existing vasa previa, is associated with higher incidence of PE, increased mean UtA PI z-score and higher probability of abnormal cord insertion, but not with increased risk for SGA or PTD. It is more common in pregnancies following ART and in women with a previous 1st trimester miscarriage.

Twin gestations are associated with an increased risk of intrahepatic cholestasis in pregnancy (ICP), probably attributed to the elevated pregnancy hormones. We report a case of a dichorionic diamniotic twin pregnancy, at the third trimester, complicated with ICP and severe, selective fetal growth restriction (sFGR). A 32-year-old primiparous woman with a dichorionic, diamniotic twin gestation conceived via in vitro fertilization (IVF) presented with pruritus at the maternity care unit at 26+4 weeks of pregnancy. Following a detailed assessment, she was diagnosed with severe sFGR and ICP. During her hospitalization, selective feticide of the FGR fetus was decided and a remarkable improvement in the symptoms and the laboratory findings of ICP was noticed. The incidence of ICP is reported to be higher in twin pregnancies, especially those conceived via IVF, compared with singletons. The optimal timing of delivery and management of twin pregnancies complicated with ICP remain unclear. In our case, selective reduction of the FGR fetus led to the resolution of ICP.
RESUMEN
Hypoglycemia represents one of the most frequent metabolic disturbances of the neonate, associated with increased morbidity and mortality, especially if left untreated or diagnosed after the establishment of brain damage. The aim of this study was to review and compare the recommendations from the most recently published influential guidelines on the diagnosis, screening, prevention and management of this common neonatal complication. Therefore, a descriptive review of the guidelines from the American Academy of Pediatrics (AAP), the British Association of Perinatal Medicine (BAPM), the European Foundation for the Care of the Newborn Infants (EFCNI), the Queensland Clinical Guidelines-Australia (AUS), the Canadian Pediatric Society (CPS) and the Pediatric Endocrine Society (PES) on neonatal hypoglycemia was carried out. There is a consensus among the reviewed guidelines on the risk factors, the clinical signs and symptoms of NH, and the main preventive strategies. Additionally, the importance of early recognition of at-risk infants, timely identification of NH and prompt initiation of treatment in optimizing the outcomes of hypoglycemic neonates are universally highlighted. All medical societies, except PES, recommend screening for NH in asymptomatic high-risk and symptomatic newborn infants, but they do not provide consistent screening approaches. Moreover, the reviewed guidelines point out that the diagnosis of NH should be confirmed by laboratory methods of BGL measurement, although treatment should not be delayed until the results become available. The definition of NH lacks uniformity and it is generally agreed that a single BG value cannot accurately define this clinical entity. Therefore, all medical societies support the use of operational thresholds for the management of NH, although discrepancies exist regarding the recommended cut-off values, the optimal treatment and surveillance strategies of both symptomatic and asymptomatic hypoglycemic neonates as well as the treatment targets. Over the past several decades, ΝH has remained an issue of keen debate as it is a preventable cause of brain injury and neurodevelopmental impairment; however, there is no clear definition or consistent treatment policies. Thus, the establishment of specific diagnostic criteria and uniform protocols for the management of this common biochemical disorder is of paramount importance as it will hopefully allow for the early identification of infants at risk, the establishment of efficient preventive measures, the optimal treatment in the first hours of a neonate's life and, subsequently, the improvement of neonatal outcomes.
RESUMEN
OBJECTIVE: Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV), namely granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis and microscopic polyangiitis constitute a group of rare systemic vasculitides, affecting small vessels. Genders are equally affected, with symptoms most commonly presenting during and/or after the fifth decade of life, but AAV may also present in younger individuals. As advanced maternal age is becoming common and safe over the last decades, it is now more feasible for middle-aged women suffering from AAV to get pregnant. Although adverse pregnancy outcomes have been thoroughly investigated in other systemic diseases, the exact prevalence of pregnancy complications and unfavorable outcomes in pregnant women with AAV has not been systematically evaluated. METHODS: We researched PubMed, Scopus, Cochrane Library and Cinahl databases until September, 2022. Three blinded investigators extracted data and assessed the risk of bias. A random effects model was used for the analysis. The outcomes studied were pre-term delivery, intrauterine growth restriction (IUGR) neonates and disease flare. RESULTS: We included six studies with 92 pregnancies in patients with AAV. The prevalence of pre-term delivery, IUGR neonates and disease flare were 18% (CI: 0.10-0.30, P=non-significant), 20% (CI: 0.11-0.33, P=non-significant) and 28% (CI: 0.09-0.59, P<0.01), respectively. CONCLUSION: The analysis demonstrated higher occurrence of adverse outcomes in pregnant women suffering from AAV accompanied by an increased risk of disease flare during pregnancy. These findings underline the importance of preconception counseling and the necessity of close monitoring in these patients similarly to other systemic inflammatory diseases.

Gynecological and general surgical conditions requiring surgical management during pregnancy constitute a medical challenge, which often entails the collaboration of numerous medical specialties. In recent years, laparoscopy in pregnancy has been accepted as a safe alternative to open surgery. This has led gynecological societies to conduct studies and issue guidelines related to laparoscopy in pregnancy, with a view to assisting and guiding clinicians and surgeons. The aim of this study was to review and compare the recommendations from various published national guidelines on laparoscopy in pregnant women. To that end, a descriptive review of guidelines from the British Society for Gynaecological Endoscopy (BSGE), the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), the Society of Obstetricians and Gynaecologists of Canada (SOCG), and the Collège National des Gynécologues et Obstétriciens Français (CNGOF) was conducted. Regarding diagnosis, the SAGES and SOCG societies recommend ultrasound as the preferred and safe imaging technique during pregnancy. In terms of the optimal timing for laparoscopic intervention, BSGE and SAGES do not restrict the laparoscopic approach based on safety, depending on the gestation week, whereas SOCG and CNGOF propose early second trimester and first and second quarter of pregnancy respectively. There is an overall consensus regarding patient positioning, initial port placement, insufflation pressure during the operation, venous thromboembolic (VTE) prophylaxis, fetal heart monitoring, and tocolysis among the reviewed guidelines. Moreover, only the BSGE mentions the need for corticosteroids, magnesium sulfate, and anti-D prophylactic administration.
RESUMEN
BACKGROUND/AIM: COVID-19 has dramatically impacted non-pandemic-related care, including preventive medicine. Our objective was to quantify the alterations in the volume of screening tests for breast and cervical cancer during the COVID-19 era compared to pre-pandemic levels. Secondarily, we discussed the causes responsible for this change, presented suggestions for screening optimization and conducted a targeted search of the relevant literature for worsening of future mortality due to screening setback. MATERIALS AND METHODS: We systematically searched Pubmed, Google Scholar and Epistemonikos for articles in English or Greek, published from March 11th, 2020, until September 14th, 2022, that illustrated quantitative variations of mammograms or Pap/HPV tests. Preprint articles, editorials and speeches were excluded. Quality of included studies was assessed via the JBI critical appraisal checklist for studies reporting prevalence data. The evidence was narratively synthesized. RESULTS: A total of 56 articles were included, being either observational studies or reports from cancer registries. Large reductions were universally identified, peaked during the first wave but partially persisted after easing of the restrictions. CONCLUSION: Our systematic review provides an updated record of the variations in screening volume and approaches screening neglect from a multidimensional perspective answering why it happened and how we could achieve recovery. A strong awareness campaign is proposed, in conjunction with triaging citizens more likely to benefit from screening. Cervical self-sampling is emphasized in the literature. Various studies displayed a potential increase in cancer mortality in the future based on predictive statistical models.

Objectives: To assess the incidence of prenatally diagnosed isolated single umbilical artery (iSUA) and its impact on major pregnancy outcomes, as well as to investigate potential risk factors. Materials and methods: A prospective study of singleton pregnancies, undergoing routine anomaly scans at 20+0-24+0 weeks of gestation, was carried out from 2018 to 2022. The effect of sonographically detected iSUA on small-for-gestational-age neonates (SGA) and preterm delivery (PTD) was evaluated using parameterized Student's t-test, nonparametric Mann-Whitney U test and the chi-square test. Multivariable logistic regression models were implemented to assess the independent association between iSUA and the main outcomes, as well as with potential risk factors, while adjusting for specific confounders. Results: The study population included 6528 singleton pregnancies and the incidence of prenatally diagnosed iSUA was 1.3%. Prenatally diagnosed iSUA had a statistically significant association with both SGA neonates (aOR: 1.909; 95% CI: 1.152-3.163) and PTD (aOR: 1.903; 95% CI: 1.035-3.498), while no association was identified between this sonographic finding and preeclampsia. With regard to risk factors, conception via assisted reproductive technology (ART) was associated with increased risk of iSUA (aOR: 2.234; 95% CI: 1.104-4.523), while no other independent predictor for the development of this anatomical variation was identified. Conclusions: Prenatally diagnosed iSUA seems to be associated with a higher incidence of SGA and PTD and is more common in pregnancies following ART, which constitutes a novel finding.
