RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: In order to help make the dream of parenthood come true for oocyte acceptors, it is essential that the procedure is not dangerous or unpleasant for oocyte donors. The aim of this study was to identify differences in safety, efficacy and patient acceptability between a traditional stimulation antagonist protocol with recombinant-FSH (rFSH) with hCG-triggering, compared with an innovative antagonist protocol with corifollitropin alfa (Elonva®) plus GnRH agonist triggering in oocyte donors. METHODS: A prospective longitudinal study was conducted at an in vitro fertilization center in Greece. The same eighty donors underwent two consecutive antagonist stimulation schemes. Primary outcomes were patient satisfaction (scored by a questionnaire) and delivery rate per donor. Secondary outcomes were mean number of cumulus-oocyte-complexes, metaphase II (MII) oocytes and ovarian hyperstimulation syndrome (OHSS) rate. RESULTS: Donors reported better adherence and less discomfort with the corifollitropin alpha + GnRH agonist-triggering protocol (p<0.001). No significant differences were identified in the clinical pregnancy rate per donor (p=0.13), the delivery rates, the number of oocytes (p=0.35), the number of MII oocytes (p=0.50) and the number of transferred embryos, between the two protocols. However, the luteal phase duration was significantly shorter (p<0.001) in the corifollitropin alpha + GnRH agonist-triggering protocol. Moreover, three cases of moderate OHSS (3.75%) were identified after hCG triggering, whereas no case of OHSS occurred after GnRH agonist ovulation induction (p=0.25). CONCLUSION: The use of corifollitropin alpha combined with a GnRH agonist for triggering is a safe, effective and acceptable protocol for oocyte donors.

RESUMO

Laparoscopic cholecystectomy is associated with attenuated acute-phase response and hypercoagulable state compared with the open procedure. Single-incision laparoscopic cholecystectomy is a new technique aiming to minimize the invasiveness of the procedure. By comparing the degree of coagulation and fibrinolysis activation after conventional multiport (CLC) and single-incision (SILC) laparoscopic cholecystectomy, we aimed to determine whether the reduced incision size induces a lower thrombophilic tendency. Thirty-two adult patients with noncomplicated symptomatic cholelithiasis were nonrandomly assigned to CLC or SILC. Prothrombin fragment 1 + 2 (F1 + 2), thrombin-antithrombin complexes (TAT), D-dimers, fibrinogen, and von Willebrand factor levels were measured at baseline, at 1st, and 24th hour, postoperatively. Twenty-six patients were finally included in the study. Fifteen patients underwent CLC (male/female: 5/10) and 11 underwent SILC (male/female: 1/10). There were no perioperative complications. An almost similar postoperative pattern and degree of activation of coagulation and fibrinolysis pathways was noted in both groups. No statistically significant differences were found between SILC and CLC for F1 + 2, TAT, D-dimers, fibrinogen, and von Willebrand factor levels, duration of surgery, length of hospital stay, and postoperative morbidity. A similar pattern and extent of coagulation and fibrinolysis activation is present in SILC and CLC, and therefore there is no difference in tendency for thrombosis. Thromboembolic prophylaxis should be considered in SILC as recommended for CLC, pharmacologic or mechanical, considering the hemorrhagic risk and the presence of additional thromboembolism risk factors. SILC appears to be a safe, feasible technique that can be recommended for its potential advantages in cosmesis and reduced incisional pain.
