Comparison of Postoperative outcomes Among Patients Treated by Male Versus Female Surgeons: A Systematic Review and Meta-analysis.

OBJECTIVE: To compare clinical outcomes of patients treated by female surgeons versus those treated by male surgeons. SUMMARY BACKGROUND DATA: It remains unclear as to whether surgical performance and outcomes differ between female and male surgeons. METHODS: We conducted a meta-analysis to compare patients' clinical outcomes-including patients' postoperative mortality, readmission, and complication rates-between female versus male surgeons. MEDLINE, Embase, CENTRAL, ICTRP, and ClinicalTrials.gov were searched from inception to September 8, 2022. The update search was conducted on July 19, 2023. We used random-effects models to synthesize data and GRADE to evaluate the certainty. RESULTS: A total of 15 retrospective cohort studies provided data on 5,448,121 participants. We found that patients treated by female surgeons experienced a lower post-operative mortality compared with patients treated by male surgeons (8 studies; adjusted odds ratio [aOR], 0.93; 95%CI, 0.88 - 0.97; I2=27%; moderate certainty of the evidence). We found a similar pattern for both elective and non-elective (emergent or urgent) surgeries, although the difference was larger for elective surgeries (test for subgroup difference P=0.003). We found no evidence that female and male surgeons differed for patient readmission (3 studies; aOR, 1.20; 95%CI, 0.83 - 1.74; I2=92%; very low certainty of the evidence) or complication rates (8 studies; aOR, 0.94; 95%CI, 0.88 - 1.01: I2=38%; very low certainty of the evidence). CONCLUSIONS: This systematic review and meta-analysis suggests that patients treated by female surgeons have a lower mortality compared with those treated by male surgeons.

Efficacy and safety of follitropin delta versus follitropin alpha/beta in infertility treatment: A systematic review and meta-analysis.

Background: Follitropin δ may be an alternative to conventional follitropin α/ß for controlled ovarian stimulation (COS) within assisted reproductive treatment (ART), but its efficacy and safety remain unknown. We performed a random-effects meta-analysis to compare the efficacy and safety of follitropin δ and follitropin α/ß. Methods: We searched randomized controlled trials comparing follitropin δ and follitropin α/ß using MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, and WHO-ITCRP on December 14, 2022. The primary outcomes were the live birth rate and the incidence of moderate or severe ovarian hyperstimulation syndrome (OHSS). The certainty of the evidence was assessed using the grading of recommendations assessment, development, and evaluation approach. The protocol was registered on the Open Science Framework. Results: Three studies involving 2682 participants were included in our meta-analysis. The results indicated that follitropin δ may result in little to no difference in live birth rates (risk ratio [RR], 1.12; 95% confidence interval [CI], 0.91-1.38; low certainty) and the incidence of moderate or severe OHSS (RR, 0.78; 95% CI, 0.48-1.26; low certainty) compared with follitropin α/ß. Conclusion: Follitropin δ may result in little to no difference in COS compared with follitropin α/ß, especially in terms of live births and safety.

Poor Prognosis in Low-Grade Endometrial Stromal Sarcoma With Cyclin-Dependent Kinase Inhibitor 2A Homozygous Deletion: A Case Study.

Low-grade endometrial stromal sarcoma (LGESS) typically has a favorable prognosis. Hormone therapy is considered the first choice of treatment for recurrent LGESS. In this report, we describe a case of recurrent LGESS where hormone therapy was ineffective, chemotherapy showed a partial response (PR), and pazopanib resulted in stable disease (SD). A 50-year-old patient with LGESS underwent a simple total hysterectomy and bilateral adnexectomy (pT1aN0M0, stage IA). Five years later, pelvic tumors and ascites were observed. Exploratory laparoscopy revealed bloody ascites, an 8 cm pelvic tumor, and extensive peritoneal dissemination. Nuclear atypia of the tumor cells was mild, pleomorphism and mitotic figures could not be confirmed, and necrosis was not observed. Immunostaining was positive for CD10 and estrogen receptor, negative for the BCL6 corepressor (BCOR), and showed a low Ki-67 index. Fluorescence in situ hybridization (FISH) examination of the tissue showed rearrangement of the JAZF zinc finger 1 (JAZF1) gene. Multigene panel testing revealed a homozygous deletion of cyclin-dependent kinase inhibitor 2A (CDKN2A). Accordingly, the patient was diagnosed with recurrent LGESS and was treated with an aromatase inhibitor, followed by medroxyprogesterone acetate; both were ineffective. The patient had a PR to chemotherapy (doxorubicin/ifosfamide) and SD to pazopanib. The patient died 1.5 years after recurrence. In conclusion, we present a case of LGESS with a poor prognosis where hormone therapy was ineffective, and chemotherapy and pazopanib were both partially effective. The poor prognosis may have been associated with the CDKN2A homozygous deletion.

Association between earthquakes and perinatal outcomes: A systematic review and meta-analysis.

BACKGROUND: Evidence for the association between earthquakes and adverse perinatal outcomes is limited. OBJECTIVES: To evaluate the association between earthquakes and perinatal outcomes including preterm birth and low birth weight. SEARCH STRATEGY: We searched studies using MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, World Health Organization International Clinical Trials Platform Search Portal, and ClinicalTrials.gov on February 9, 2023. SELECTION CRITERIA: We included before-and-after studies that evaluated the associations between earthquakes and perinatal outcomes in women living in affected areas. DATA COLLECTION AND ANALYSIS: Two independent reviewers extracted data. We calculated the pooled odds ratio (OR) with the random-effects model. We analyzed outcomes in subgroups of Asians and others. We evaluated the certainty of evidence with the Grading of Recommendations Assessment, Development and Evaluation system. MAIN RESULTS: We included 2 607 405 women in 13 studies. Earthquakes may not increase preterm birth (nine studies, 1 761 760 participants: OR 1.10, 95% confidence interval [CI] 0.98-1.24, low certainty of evidence) or low birth weight (seven studies, 1 753 891 participants: OR 1.10, 95% CI 0.94-1.28, low certainty of evidence). Subgroup analyses showed that earthquakes may be associated with an increase of preterm birth among populations in Asia (OR 1.44, 95% CI 1.07-1.95), but this was not evident in others (OR 0.93, 95% CI 0.83-1.05). CONCLUSIONS: Perinatal outcomes might not change after earthquakes. Further research on the association between earthquakes and perinatal outcomes, combined with an assessment of the characteristics of the region, is needed.

Efficacy and Safety of the Surgery-First Approach Compared to the Chemotherapy-First Approach for Treating Low-Risk Gestational Trophoblastic Neoplasia: A Systematic Review and Meta-Analysis.

For gestational trophoblastic neoplasia (GTN) affecting women of reproductive age, the chemotherapy-first approach is often preferred over the surgery-first approach. Low-risk GTN is treated with a chemotherapy-first approach, but the number of courses required can affect fertility. A surgery-first approach may decrease the number of chemotherapy courses, but its efficacy and safety compared to a chemotherapy-first approach are unclear. Thus, we investigated the efficacy and safety of the surgery-first approach compared to the chemotherapy-first approach in treating low-risk GTN. We searched the MEDLINE, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform databases for relevant articles in July 2023. A systematic review and meta-analysis of outcome measures were conducted using a random-effects model. The primary outcomes were remission, the mean number of chemotherapy courses required to cure, and adverse events. The certainty of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. This study protocol was registered in the Open Science Framework (https://osf.io/kysvn/). Studies for low-risk GTN included a qualitative synthesis (with 2,192 participants and ten studies, eight of which were about second uterine curettage and two about hysterectomy) and a meta-analysis (with 138 participants and two randomized controlled trials (RCTs) that compared first-line treatments of second uterine curettage and chemotherapy). Second uterine curettage may result in little to no difference in remission (risk ratio: 1.00, 95% confidence interval: 0.96-1.05; low certainty) and a slight reduction in adverse events (risk ratio: 0.87, 95% confidence interval: 0.47-1.60; low certainty). The evidence is very uncertain on the mean number of chemotherapy courses (mean difference: 2.84 lower, 95% confidence interval: 7.31 lower to 1.63 higher; very low certainty). Based on clinical outcomes, second uterine curettage can be comparable to the chemotherapy-first approach as a first-line treatment option for low-risk GTN; however, the overall certainty of the evidence was low or very low.

App-based interventions for the prevention of postpartum depression: a systematic review and meta-analysis.

BACKGROUND: This study explored whether psychosocial intervention applications (apps) are effective in preventing postpartum depression. METHODS: We conducted an initial article search on 26 March 2020, and the updated search on 17 March 2023 on the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, Scopus, PsycINFO, CINAHL, and ProQuest Dissertations & Theses A&I. Furthermore, we searched the International Clinical Trials Platform Search Portal (ICTRP), and Clinical Trials. RESULTS: We identified 2515 references, and sixteen studies were ultimately included in this review. We conducted a meta-analysis of two studies on the onset of postpartum depression. There were no significant differences between the intervention and control groups (RR 0.80; 95% CI 0.62 to 1.04; P = 0.570). We performed a meta-analysis of the Edinburgh Postnatal Depression Scale (EPDS). The intervention group had significantly lower EPDS scores than the control group (mean difference -0.96; 95% CI -1.44 to -0.48; P < 0.001, I2 = 82%, Chi2 = 62.75, P < 0.001; high heterogeneity). CONCLUSION: This study presents the results of current RCTs on interventions with apps, including an app with an automated psychosocial component for preventing postpartum depression that has been conducted. These apps improved the EPDS score; furthermore, they may prevent postpartum depression.

Efficacy of intravenous dexamethasone on postoperative pain after caesarean delivery under spinal anaesthesia with an intrathecal long-acting opioid: a systematic review and meta-analysis.

PURPOSE: Intravenous dexamethasone is recommended in elective caesarean delivery to decrease postoperative pain. However, the efficacy of spinal anaesthesia with an intrathecal long-acting opioid such as morphine or diamorphine for caesarean delivery has not been systematically investigated. METHODS: We searched all randomized controlled trials (RCTs) of pregnant women undergoing caesarean delivery under spinal anaesthesia with an intrathecal morphine or diamorphine via MEDLINE, CENTRAL, EMBASE, ICTRP, and ClinicalTrials.gov on May 18, 2022. Primary outcomes were time to first rescue analgesia, consumption of oral morphine equivalents, and incidence of drug-related adverse reactions. We evaluated the risk of bias for each outcome using the Risk of Bias 2. We conducted a meta-analysis using a random effects model. We evaluated the certainty of evidence with the GRADE approach. RESULTS: Five RCTs (455 patients) were included. The results of intravenous dexamethasone were as follows: time to first rescue analgesia (mean difference [MD] 0.99 h, 95% confidence interval [CI] - 0.86 to 2.84; very low certainty) and consumption of oral morphine equivalents (MD - 6.55 mg, 95% CI - 17.13 to 4.02; moderate certainty). No incidence of drug-related adverse reactions was reported (very low certainty). CONCLUSION: The evidence was very uncertain about the efficacy of intravenous dexamethasone on time to first rescue analgesia and the incidence of drug-related adverse reactions. Intravenous dexamethasone probably reduces the consumption of oral morphine equivalents. Anaesthesiologists might want to consider intravenous dexamethasone for postoperative pain after caesarean delivery under spinal anaesthesia with an intrathecal long-acting opioid.

Association between placental location and neonatal outcomes in manual fundal pressure-assisted vaginal deliveries: A retrospective single-center study in Japan.

AIM: Manual fundal pressure (MFP) is still used to assist vaginal deliveries during the second stage of labor in predominantly lower-middle income countries; however, there is insufficient evidence on the risk factors in MFP-assisted vaginal deliveries for adverse neonatal outcomes. The aim of the present study was to investigate the association between placental location and neonatal outcomes in MFP-assisted vaginal deliveries. METHODS: The present study was a single-center retrospective cohort study in patients with all MFP-assisted vaginal singleton deliveries from January 2016 to December 2020. Placental location was divided into two categories: posterior-lateral and anterior-fundal. The primary outcome was a neonatal adverse composite including umbilical artery blood pH <7.2, Apgar score <7 at 5 min, neonatal intensive care unit admission and neonatal resuscitation. We used multivariable logistic regression models to investigate the association between placental location and neonatal outcomes. RESULTS: We extracted 522 MFP-assisted deliveries among 5053 vaginal deliveries. The proportion of posterior-lateral and anterior-fundal placentation was 239 (45.8%) and 283 (54.2%), respectively. The crude prevalence of neonatal composite outcome in the anterior-fundal group was significantly higher than that in the posterior-lateral group (39.6% vs. 28.9%; p = 0.013). Multivariable logistic regression analysis found that the prevalence of neonatal adverse outcome in the anterior-fundal group was significantly higher compared with the posterior-lateral group (adjusted odds ratio, 1.52; 95% confidence interval, 1.04-2.23). CONCLUSION: Anterior-fundal placentation was significantly associated with an increased risk of neonatal adverse outcomes compared to posterior-lateral placentation in MFP-assisted vaginal deliveries.

Resuscitative endovascular balloon occlusion of the aorta for life-threatening postpartum hemorrhage: A nationwide observational study in Japan.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is used for postpartum hemorrhage (PPH), which is one of the leading causes of maternal mortality worldwide; however, its utility in the obstetrics setting remains unclear. Thus, this study aimed to describe the characteristics, demographics, and mortality of patients with PPH who underwent REBOA. METHODS: We used the Japanese Diagnosis Procedure Combination inpatient database to identify patients with PPH who underwent REBOA from April 2012 to March 2020. We examined the patients' characteristics, interventions administered, and in-hospital mortality. RESULTS: We identified 143 patients with PPH who underwent REBOA. The most common cause of PPH was atonic postpartum hemorrhage (52.4%), followed by disseminated intravascular coagulation (29.4%) and amniotic fluid embolism documented (11.2%). Among patients who delivered at hospitals in which REBOA was performed (n = 55), 38.2% of patients experienced preterm births, and 70.9% delivered via cesarean delivery. The proportion of patients who underwent transcatheter arterial embolization and hysterectomy was 53.8% and 16.1%, respectively. In-hospital mortality was 7.0%. CONCLUSION: The results of the present study could be helpful in clinical decision making and providing patients and families with additional treatment options for PPH. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Clinical characteristics of a novel "Type 3" vasa previa: case series at a single center.

OBJECTIVE: Vasa previa is a condition in which fetal blood vessels are located on fetal membranes within 2 cm of the internal cervical os. Vasa previa has been classified into two types: Type 1, in which vessels connect a velamentous umbilical cord to the placenta, and Type 2, in which vessels connect the lobes of a bilobed placenta or the placenta to a succenturiate lobe. However, there are also atypical cases that cannot be classified into these two types. These cases are manifested by a center or marginal cord insertion with a normal shaped placenta, and fetal vessels were also located on membranes around the internal cervical os. These cases were recently proposed as Type 3 vasa previa. The present study investigated the incidence of Type 3 vasa previa and elucidated differences in clinical and ultrasonographical characteristics between traditional types and Type 3. METHODS: This was a single-center observational study using a cohort of all vasa previa cases between January 2010 and April 2020. RESULTS: Among 8,723 deliveries, there were 14 cases (0.16%) of vasa previa, all of which were diagnosed prenatally by US, not after vaginal delivery or CS. There were 9 (64%), 0, and 5 (36%) cases of Types 1, 2, and 3, respectively. All 5 Type 3 cases had only one fetal aberrant vessel of vasa previa, while 6 out of 9 Type 1 cases (67%) had two or more aberrant vessels. Seven Type 1 cases (78%) possessed two or more known risk factors, such as velamentous cord insertion, whereas all Type 3 cases only had one. Difficulties were associated with diagnosing two out of the 14 cases of vasa previa using routine transvaginal ultrasonography (TVUS). In these cases, the aberrant fetal vessel of vasa previa was only one vein with a thin wall that was not clearly visualized by gray-scale TVUS as well as slow flow that was easily misread by color-Doppler. These cases were ultimately diagnosed as vasa previa based on non-pulsatile flow detected by color and pulsed Doppler. CONCLUSIONS: The present results suggest that Type 3 may account for a large proportion of vasa previa cases. Most Type 3 cases may present with only one fetal aberrant vessel of vasa previa and fewer risk factors, suggesting that the diagnosis of vasa previa may be more challenging in Type 3 cases than in the other types. Vasa previa with a venous vasa previa needs to be considered because of the difficulties associated with an antenatal diagnosis due to unclear imaging of the vasculature or the lack of specific color Doppler flow patterns. Pulsed Doppler imaging may be helpful for the diagnosis of these cases.

Uterine torsion with scoliosis.

Clinicians should consider uterine torsion as a differential diagnosis for acute abdominal pain in women with scoliosis. Scoliosis may have led to an abnormal pelvic structure, making it easier for pelvic organs to twist.

Pyosalpinx due to Cronobacter sakazakii in an elderly woman.

BACKGROUND: Cronobacter sakazakii (C. sakazakii) is a bacterium known to cause severe neonatal infections in premature infants with the consumption of contaminated powdered milk formula. Adult infections are rare, and there have been no reports of pyosalpinx due to C. sakazakii to date. CASE PRESENTATION: We report a case of left pyosalpinx due to C. sakazakii in a sexually inactive postmenopausal woman. A 70-year-old woman presented to our hospital with left lower abdominal pain and fever. Abdominal computed tomography disclosed a cystic mass continuous with the left edge of the uterus. Urgent laparotomy revealed a ruptured left pyosalpinx with pus-like content. Left salpingo-oophorectomy, resection of the right tube, and washing of the abdominal cavity with saline were performed. Pathological examination of the left adnexa showed tubal tissue with acute inflammation and inflammatory exudate, which were compatible with pyosalpinx, and pus culture yielded C. sakazakii. CONCLUSIONS: This is the first case report of pyosalpinx due to C. sakazakii. Cronobacter sakazakii infections in adult women might occur in the elderly, whose immunity has weakened. Further accumulation of cases of C. sakazakii infection is needed to clarify the etiology and behavior of C. sakazakii in adults.

Association between the number of pulls and adverse neonatal/maternal outcomes in vacuum-assisted delivery.

OBJECTIVES: To determine the association between the number of pulls during vacuum-assisted deliver and neonatal and maternal complications. METHODS: This was a single-center observational study using a cohort of pregnancies who underwent vacuum-assisted delivery from 2013 to 2020. We excluded pregnancies transitioning to cesarean section after a failed attempt at vacuum-assisted delivery. The number of pulls to deliver the neonate was categorized into 1, 2, 3, and ≥4 pulls. We used logistic regression models to investigate the association between the number of pulls and neonatal intensive care unit (NICU) admission and maternal composite outcome (severe perineal laceration, cervical laceration, transfusion, and postpartum hemorrhage ≥500 mL). RESULTS: We extracted 480 vacuum-assisted deliveries among 7,321 vaginal deliveries. The proportion of pregnancies receiving 1, 2, 3, or ≥4 pulls were 51.9, 28.3, 10.8, and 9.0%, respectively. The crude prevalence of NICU admission with 1, 2, 3, and ≥4 pulls were 10.8, 16.2, 15.4, and 27.9%, respectively. The prevalence of NICU admission, amount of postpartum hemorrhage, and postpartum hemorrhage ≥500 mL were significantly different between the four groups. Multivariable logistic regression analysis found the prevalence of NICU admission in the ≥4 pulls group was significantly higher compared with the 1 pull group (adjusted odds ratio, 3.3; 95% confidence interval, 1.4-7.8). In contrast, maternal complications were not significantly associated with the number of pulls. CONCLUSIONS: Vacuum-assisted delivery with four or more pulls was significantly associated with an increased risk of NICU admission. However, the number of pulls was not associated with maternal complications.
