RESUMEN
BACKGROUND: Gynecological cancer is one of the highest risk factors for cancer-associated thrombosis (CAT). Although low-molecular-weight heparin (LMWH) is recommended as an anticoagulant for treating CAT, recent studies have shown that direct oral anticoagulants (DOACs) are an acceptable alternative. Patients with cancer require a series of chemotherapies concomitantly with DOAC administration; however, the extent to which these drugs influence DOAC blood concentrations is unknown. In this study, we measured the plasma concentration of edoxaban during chemotherapy for gynecological cancers to determine its safety. METHODS: Patients histologically diagnosed with ovarian or uterine corpus cancer and CAT were recruited after primary surgery and before the initiation of postoperative adjuvant chemotherapy, including paclitaxel. Patients were administered edoxaban (30 or 60 mg) orally for CAT. The plasma concentrations of edoxaban and active factor Xa were determined and their percentage change before and after chemotherapy was calculated. Additionally, blood coagulation tests were analyzed. RESULTS: Sixteen patients with gynecological cancer (12 with ovarian cancer and 4 with uterine corpus cancer) were enrolled. Among these, 15 samples were collected one day after chemotherapy initiation. During chemotherapy, the trough concentration of edoxaban changed from 17.6 ± 10.6 to 20.0 ± 15.6 ng/ml, and the mean percentage change in edoxaban concentration was 14.5%. Therefore, the trough concentrations of edoxaban, which represent excretion capacity, were not significantly increased by chemotherapy with paclitaxel. The area under the plasma edoxaban concentration-time curve and the active factor Xa concentration were also unaffected. CONCLUSION: Patients with CAT and ovarian or uterine corpus cancer administered edoxaban orally showed no significant increase in the trough concentration of edoxaban while undergoing chemotherapy. This suggests the safety of edoxaban use during the treatment of gynecological cancers. TRIAL REGISTRATION: EGCAT study; Japan Registry of Clinical Trials, jRCTs051190024.
RESUMEN
BACKGROUND: This study assesses the feasibility of minimally invasive surgery (MIS) for well-selected epithelial ovarian cancer (EOC) patients. METHODS: We performed a review of data prospectively collected from a single center from 2017 to 2022. Only patients with histologically confirmed EOC, with a tumor diameter of less than 10 cm, were eligible. We also performed a meta-analysis of similar studies comparing the outcomes of laparoscopy and laparotomy. We used MINORS (Methodological Index for Non-Randomized Studies) to assess the risk of bias and calculated the odds ratio or mean difference. RESULTS: Eighteen patients were included; 13 in re-staging group, four in PDS group, and one in IDS group. All achieved complete cytoreduction. One case was converted to laparotomy. The median number of removed pelvic lymph nodes was 25 (range 16-34), and 32 (range 19-44) for para-aortic nodes. There were two (15.4%) intraoperative urinary tract injuries. The median follow-up was 35 months (range 1-53). Recurrence was observed in one case (7.7%). Thirteen articles for early-stage ovarian cancer were included in our meta-analysis. Analysis of the pooled results found that MIS had a higher frequency of spillage (OR, 2.15; 95% CI 1.27-3.64). No differences were observed in recurrence, complications, or up-staging. CONCLUSIONS: Our experience supports the possibility of conducting MIS for EOC in well-selected patients. Except for spillage, our meta-analysis findings are consistent with previous reports, the majority of which were also retrospective. Ultimately, randomized clinical trials will be needed to authenticate the safety.

BACKGROUND: Preoperative anemia affects perioperative outcomes and often causes fatigue and psychological disorders. Therefore, anemia should be treated before a patient undergoes surgery. Ninjin'yoeito (NYT), a Japanese Kampo medicine composed of ginseng and Japanese angelica root with the other 10 herbs, is administered for anemia, fatigue and anxiety; however, there are a few reports that have prospectively examined the effects of NYT before surgery for gynecological diseases. Hence, we tended to investigate its efficacy and safety. METHODS: In this open-label randomized trial, women with gynecological diseases accompanied by preoperative anemia (defined as < 11.0 g/dL Hemoglobin [Hb]) were randomly assigned (1:1) into the iron supplementation and NYT groups. Patients of the iron supplementation group and the NYT group received 100 mg/day iron supplementation with and without NYT (7.5 g/day) for at least 10 days before surgery. The primary endpoint was improvement in Hb levels before and after treatment, and Cancer Fatigue Scale (CFS) and Visual Analogue Scale for Anxiety (VAS-A) scores between groups. Statistical analyses were performed with Wilcoxon signed rank test, Wilcoxon rank sum test, and Fisher's exact test as appropriate. RESULTS: Forty patients were enrolled of whom 30 patients were finally analyzed after allocating 15 to each group. There was no difference in the characteristics between both groups. Hb significantly increased in both groups (iron supplementation group, 9.9 ± 0.8 g/dL vs. 11.9 ± 1.6 g/dL; NYT group, 9.8 ± 1.0 g/dL vs. 12.0 ± 1.0 g/dL); the difference in the elevations in Hb between both groups was statistically insignificant (P = 0.72). Contrarily, CFS (17.9 ± 10.2 vs. 8.1 ± 5.2) and VAS-A (56 mm (50-70) vs. 23 mm (6-48)) scores were significantly decreased only in the NYT group and these changes were greater in the NYT group (∆CFS, P = 0.015; ∆VAS-A, P = 0.014). Liver dysfunction occurred in one patient of the NYT group. CONCLUSIONS: For treating preoperative anemia in women with gynecological conditions, NYT administration along with iron supplementation safely and efficiently improved the preoperative fatigue and anxiety in addition to the recovery from anemia.

PURPOSE: The goal of this study was to evaluate, using definitive diagnostic criteria, the incidence of lymphocyst formation following pelvic lymphadenectomy for gynecological cancer, and to compare rates between the approaches of laparoscopy and laparotomy. METHODS: We retrospectively reviewed the medical records of all patients who underwent pelvic lymphadenectomy for cervical or endometrial cancer between March of 2010 and March of 2016. We defined a lymphocyst as a circumscribed collection of fluid within the pelvic cavity, with a diameter of 2 cm or more, as diagnosed with ultrasound or computed tomography. RESULTS: During the six-year observational period, a pelvic lymphadenectomy was conducted in 196 women with clinical stage I uterine cancer; 90 cases underwent laparoscopy, 106 underwent laparotomy. The minimally invasive laparoscopic group had a lower estimated blood loss (p < 0.01), shorter hospital stay (p < 0.01). Lymphocysts were observed in 14.4% (13/90) of the laparoscopy cases, and in 15.1% (16/106) of the laparotomy cases which means no significant difference of lymphocyst (p = 1.00). The median size of symptomatic lymphocyst was significantly larger in laparotomy group than in laparoscopy group (4.8 cm v.s. 2.8 cm, median) (p = 0.04). Symptomatic lymphocysts were more common in laparotomy [7/90 (7.8%) vs 14/106 (13.2%) (p = 0.253)]. CONCLUSIONS: In a retrospective analysis with a strict diagnostic criteria, we could find no statistical difference in lymphocyst occurrence between laparoscopy and laparotomy. The median size of the lymphocyst was bigger and lymphocyst was likely to be symptomatic in the laparotomy group.

BACKGROUND: In recent years, feelings of isolation among mothers caring for small children has become a significant social issue in Japan. The purpose of this study is to develop a message to alleviate their loneliness, to evaluate the impact of social networking sites (SNS) for delivering such messages, and to propose means of more effective information transmission to promote health for mothers raising small children. METHODS: Our study was conducted in two stages, first an interview and then a cross-sectional study of the mothers involving a questionnaire survey. The interview was targeted two public-health nurses caring for mothers. Based on these interviews, we developed six messages intended to alleviate the mothers' sense of loneliness, which were vetted by seven mothers. The second stage was to conduct a questionnaire survey of mothers both before and after our selected message as advertisement on Instagram and analyzed the effect. The surveys were collected during routine child health check-ups in the City of Takatsuki, Japan. RESULTS: From the six draft messages created based on interviews with public health nurses, we selected the message that most relieves the feeling of loneliness of the mothers who are raising small children. The survey questionnaire was taken by 494 mothers prior to our posting of Instagram advertisements (ads), and afterwards by 419 mothers. The percentage of mothers feeling loneliness tended to decrease after reading the messages (before ads.:8.1%, after ads.:5.8%). 8.6% of the mothers (36/419) remembered seeing the Instagram ads. Mothers with financial anxiety were significantly more likely to have remembered seeing the Instagram ads (p < 0.01). CONCLUSIONS: Our results indicate that usefulness of SNS messaging for mothers raising small children may reduce their feeling of loneliness. Among the SNS, disseminating child-rearing information on Instagram may be more effective for people with financial instability.

Purpose: To assess the clinical efficacy of personalized embryo transfer (pET) guided by a new endometrial receptivity test, ERPeakSM, in patients with recurrent implantation failure (RIF). Methods: Recurrent implantation failure patients of all ages at two private Japanese clinics from April 2019 to June 2020 were retrospectively analyzed. The intervention group (n = 244) received pET in accordance with endometrial receptivity testing results and was compared to control group (n = 306) receiving standardized timing, non-personalized embryo transfer (npET). In propensity score matching analysis, the clinical pregnancy rate (CPR) and live birth rate (LBR) were compared between groups, and a subanalysis of advanced maternal age (AMA) (≥38 years old) versus non-AMA (<38 years old) patients was also conducted. Results: The CPR and LBR of the pET group were significantly higher than those of the npET group (37.7% vs. 20.0%, adjusted OR: 2.64; 95%CI, 1.70-4.11, p < 0.001 and 29.9% vs. 9.7%, adjusted OR: 4.13; 95%CI, 2.40-7.13, p < 0.001, respectively). Furthermore, in the subanalyses, the CPR and LBR of the pET group were significantly higher than those of the npET group in both the AMA non-AMA patients. Conclusions: The new ERPeakSM endometrial receptivity test is a useful alternative diagnostic tool for poor-prognosis patients, regardless of age.
RESUMEN
AIM: A feeling of isolation childcare mothers' face is a serious social problem in Japan because the relationships with mothers and local communities have grown sparser. The purpose of this study was to clarify the feelings of isolation of mothers during childcare and the factors related to it. METHODS: We conducted a questionnaire survey in Yao City, Osaka. We mailed out a questionnaire survey of 1293 mothers with infants who had either a 4-month or 42-month routine health checkup during the period from September to December of 2018. RESULTS: There was no association between "feeling lonely while raising my child" and the absence of "people who helped raise my children." On the other hand, it was found that the mothers' inner feelings, such as "I wasn't satisfied with my childcare environment" (OR: 2.55, 95% CI: 1.32-4.91, p = 0.0052) or "I lacked confidence in my own childcare abilities" (OR: 6.21, 95% CI: 4.31-8.95, p < 0.0001), were associated with their sense of loneliness. CONCLUSIONS: Mothers' "sense of loneliness" was shown to be best correlated with their dissatisfaction with the environment of their childcare and with their lack of confidence in raising their own children.

BACKGROUND: A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes. METHODS: This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed. RESULTS: The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04). CONCLUSIONS: PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Background and Objectives: Since spontaneous uterine rupture in the mid-trimester is rare, maternal and fetal outcomes in subsequent pregnancies remain unclear. Therefore, this study aimed to examine the maternal and fetal outcomes of subsequent pregnancies after prior mid-trimester uterine rupture. Materials and Methods: A systematic review using PubMed, the Cochrane Central Register of Controlled Trials, and Scopus until 30 September 2021, was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The studies that clarified the maternal and fetal outcomes after prior mid-trimester uterine rupture and our case (n = 1) were included in the analysis. Results: Among the eligible cases, there were five women with eight subsequent pregnancies after prior mid-trimester uterine rupture. The timing of prior mid-trimester uterine rupture ranged from 15 to 26 weeks of gestation. The gestational age at delivery in subsequent pregnancies was 23-38 gestational weeks. Among the included cases (n = 8), those involving prior mid-trimester uterine rupture appeared to be associated with an increased prevalence of placenta accreta spectrum (PAS) (n = 3, 37.5%) compared with those involving term uterine rupture published in the literature; moreover, one case exhibited recurrent uterine rupture at 23 weeks of gestation (12.5%). No maternal deaths have been reported in subsequent pregnancies following prior mid-trimester uterine rupture. Fetal outcomes were feasible, except for one pregnancy with recurrent mid-trimester uterine rupture at 23 weeks of gestation, whose fetus was alive complicated by cerebral palsy. Conclusions: Our findings suggest that clinicians should be aware of the possibility of PAS and possible uterine rupture in pregnancies after prior mid-trimester uterine rupture. Further case studies are warranted to assess maternal and fetal outcomes in pregnancies following prior mid-trimester prior uterine rupture.

BACKGROUND: HPV vaccines are well known to prevent several devastating HPV-associated cancers-when administered before sexual activity begins. We have previously found that mothers in Japan play an important role in a young girl's vaccination decision-making, and that educational intervention with the mothers positively changed their attitude towards the HPV vaccine. The role of fathers is still unclear. We report here similar effects can be achieved by an educational intervention with the fathers. METHOD: We conducted an online survey of 1648 Japanese fathers as having 13-18 year-old daughters. In this group, 1450 fathers had HPV-unvaccinated daughters. Roughly half, 721, were supplied an educational sheet concerning cervical cancer, which included information regarding the safety and efficacy of the HPV vaccine, the other 729 did not receive the sheet. Afterwards, a self-administered questionnaire obtained information from both groups of fathers. We evaluated their attitudes and intentions to inoculate their daughters and willingness to be associated with the vaccination decision-making process. RESULTS: Paternal education with an information sheet was associated with an increased odds ratio for changing the father's attitude in a positive direction, but it was not associated with improving the father's intention to their have their daughters inoculated, nor the father's willingness to be associated with the decision-making process. CONCLUSION: While educational intervention can promote a father's positive attitude towards HPV vaccination, it is ineffective at promoting a positive intention to follow through to inoculate their daughters or improving their willingness to assist in the decision-making process.

AIM: Epithelial ovarian cancer (EOC) can be a devastating diagnosis in women of reproductive age who desire future fertility. However, in early-stage disease, fertility-sparing surgery (FSS) can be considered in appropriately selected patients. METHODS: This is a narrative descriptive review of the recent literature on FSS for EOC from oncologic, reproductive and endocrinologic perspectives. RESULTS: The recurrence rate following FSS performed for stage I EOC in published retrospective studies collectively is 13% but ranges from 5 to 29%, while mortality ranges from 0 to 18%. Five-year disease-free survival following FSS is over 90% but decreases with higher stage and grade. Recurrences following FSS are more likely to be localized with a more favorable prognosis compared to recurrences following radical surgery. Adjuvant chemotherapy is recommended in women with high-risk disease, and strategies to minimize gonadotoxicity during chemotherapy such as gonadotropin-releasing hormone (GnRH) agonists may be considered. Oocyte, embryo and/or ovarian cryopreservation can also be offered to patients desiring future biologic children. Reproductive outcomes following FSS, including pregnancy and miscarriage rates, resemble those of the general population, with a chance of successful pregnancy of nearly 80%. CONCLUSION: In retrospective data, FSS appears to be oncologically safe in stage IA and IC grade 1-2 non-clear cell EOC. In patients with grade 3 tumors or clear cell histology, treatment can be individualized, weighing a slightly higher risk of recurrence with fertility goals. A multidisciplinary approach with oncology and reproductive endocrinology may be of utility to help these patients achieve their fertility goals.

BACKGROUND: Historically, the Cox proportional hazard regression model has been the mainstay for survival analyses in oncologic research. The Cox proportional hazard regression model generally is used based on an assumption of linear association. However, it is likely that, in reality, there are many clinicopathologic features that exhibit a nonlinear association in biomedicine. OBJECTIVE: The purpose of this study was to compare the deep-learning neural network model and the Cox proportional hazard regression model in the prediction of survival in women with cervical cancer. STUDY DESIGN: This was a retrospective pilot study of consecutive cases of newly diagnosed stage I-IV cervical cancer from 2000-2014. A total of 40 features that included patient demographics, vital signs, laboratory test results, tumor characteristics, and treatment types were assessed for analysis and grouped into 3 feature sets. The deep-learning neural network model was compared with the Cox proportional hazard regression model and 3 other survival analysis models for progression-free survival and overall survival. Mean absolute error and concordance index were used to assess the performance of these 5 models. RESULTS: There were 768 women included in the analysis. The median age was 49 years, and the majority were Hispanic (71.7%). The majority of tumors were squamous (75.3%) and stage I (48.7%). The median follow-up time was 40.2 months; there were 241 events for recurrence and progression and 170 deaths during the follow-up period. The deep-learning model showed promising results in the prediction of progression-free survival when compared with the Cox proportional hazard regression model (mean absolute error, 29.3 vs 316.2). The deep-learning model also outperformed all the other models, including the Cox proportional hazard regression model, for overall survival (mean absolute error, Cox proportional hazard regression vs deep-learning, 43.6 vs 30.7). The performance of the deep-learning model further improved when more features were included (concordance index for progression-free survival: 0.695 for 20 features, 0.787 for 36 features, and 0.795 for 40 features). There were 10 features for progression-free survival and 3 features for overall survival that demonstrated significance only in the deep-learning model, but not in the Cox proportional hazard regression model. There were no features for progression-free survival and 3 features for overall survival that demonstrated significance only in the Cox proportional hazard regression model, but not in the deep-learning model. CONCLUSION: Our study suggests that the deep-learning neural network model may be a useful analytic tool for survival prediction in women with cervical cancer because it exhibited superior performance compared with the Cox proportional hazard regression model. This novel analytic approach may provide clinicians with meaningful survival information that potentially could be integrated into treatment decision-making and planning. Further validation studies are necessary to support this pilot study.

BACKGROUND: Endometrial carcinoma (EC) is rarely diagnosed during pregnancy. Therefore, the histopathological findings, clinical course, and gross appearance of the resected uterus during pregnancy are not well known. We present a case of EC diagnosed during pregnancy. In addition, we reviewed the literature dating from January 1995 to March 2019 for cases of EC diagnosed during pregnancy and within 15 months after pregnancy, and we discussed this topic to improve the understanding of this rare condition. CASE PRESENTATION: A 35-year-old woman underwent an urgent cesarean delivery in gestational week 35 due to antepartum bleeding caused by placenta previa. Hysterectomy was performed with the diagnosis of placenta accreta spectrum (PAS). Remarkably, the postoperative gross and histopathological examinations revealed an endometrioid adenocarcinoma (grade 1). The histopathological findings revealed a pattern similar to that of EC not related with pregnancy. Immunohistochemistry revealed an overexpression of the estrogen and progesterone receptors; however, the p53 expression was negative. We performed laparoscopic bilateral salpingo-oophorectomy and pelvic lymphadenectomy 102 days after the cesarean hysterectomy, and confirmed surgical stage IA without metastases. Our patient has had no recurrence in 4 years after the cesarean delivery. An electronic search of the literature revealed 25 cases of EC (including our case) diagnosed during or after pregnancy. Sixteen of the 25 patients were diagnosed after abortions in the first trimester, 9 were diagnosed within 14 months of childbirth, and our case was the first with diagnosis from a surgical specimen of peripartum hysterectomy due to the PAS. In 23 of the 25 cases endometrioid adenocarcinoma grade 1 to 2 was found, and it seemed to have a good prognosis. CONCLUSION: The present findings suggest that careful examination of a resected uterus is essential, even when surgery is performed for an obstetric indication. Our case is an extremely rare case of EC during pregnancy; the histopathological pattern was similar to that of typical EC, and no recurrence was noted. The high levels of estrogen and progesterone during pregnancy did not seem to promote tumor progression in our case.

AIM: In this study, we aimed to investigate whether there was a significant prognostic difference between single and multiple cervical dilations when inducing second-trimester abortion. METHODS: We conducted a retrospective review of 238 pregnant women who underwent termination of pregnancy at 12-21 weeks of gestation at Osaka University Hospital in Osaka, Japan, between January 2010 and May 2018. Termination of pregnancy was performed by vaginal administration of 1 mg gemeprost every 3 h for up to five doses per day after uterine cervical dilation using lamicel. RESULTS: The women were categorized into two groups: 191 women had a delivery time of <24 h, whereas 47 had delivery times >24 h. Contrasting the groups, there were significant differences with regard to numbers of primiparas (88 [46.1%] and 32 [68.1%], respectively) and lamicel exchanges ± SD (1.9 ± 0.67 for <24 h and 2.4 ± 0.87 for >24 h, respectively). Additionally, we compared the prognosis of primiparas that received just a single lamicel with that of primiparas that had ≥2 exchanged, but no significant differences were noted in the number of patients with a delivery time of >24 h and the number of used gemeprost. CONCLUSION: Primipara is a risk factor for delayed delivery time of induced abortion. However, increasing the number of exchanged lamicel did not significantly reduce the delivery time; therefore, it should be performed as minimally as possible.

BACKGROUND: We developed a dedicated blunt straight needle with No. 2 polydioxanone sutures (2-Monodiox®) for uterine compression sutures (UCSs) and aimed to assess the outcomes and complication rates of UCSs for postpartum hemorrhage by comparing with commercially available needle and suture types. METHODS: A retrospective analysis was performed between January 2010 and February 2018. During the study period, two types of commercially available sutures and 2-Monodiox® were used. PubMed, MEDLINE, and Scopus databases were searched for English articles published between January 1997 and May 2017 using search terms related to the suture and needle types for UCSs to discuss the dedicated needles and sutures for UCS. RESULTS: The analysis included 47 cases of UCSs for the uterine body with three suture types (No. 0 polydioxanone, 7 cases; No. 1 poliglecaprone 25, 21 cases; and No. 2 polydioxanone, 19 cases). B-Lynch suture using No. 0 sutures was associated with a significantly lower uterine preservation rate than those with Nos. 1 and 2 sutures (42.9% vs. 95.2 and 89.5%, respectively; p < 0.01). A modified Hayman suture technique was performed using 2-Monodiox® sutures, which achieved a similar uterine preservation rate compared with B-Lynch suture using No. 1 poliglecaprone 25 sutures. No patients developed severe complications. The literature review showed that no dedicated sutures have developed for UCSs. Three dedicated needles for UCSs have been developed, and 2-Monodiox® is the first dedicated blunt straight needle for UCSs. CONCLUSION: Our data showed that No. 0 sutures should not be used for B-Lynch suture. The uterine preservation rate is similar for 2-Monodiox® with modified Hayman suture and No. 1 poliglecaprone 25 sutures with B-Lynch suture, without the occurrence of severe complications.

BACKGROUND: This study aimed to identify and review associations between the types of sutures used for uterine compression suture (UCS) and its outcomes in postpartum hemorrhage. METHODS: An electronic search using PubMed and Scopus databases was performed. We included the English articles reported from January 1, 1997, to May 31, 2017, using search words or terms regarding the types of suture and needle used for UCSs. We only included studies describing the sutures in the systematic review. RESULTS: We found 196 studies and included 76 (38.8%) in our analysis. We collected data on maternal outcomes for 924 patients and categorized them. Of the 76 studies, suture sizes 0, 1, and 2 were used in 6, 44, and 32 articles, respectively (some studies used multiple sutures). Of the 45 studies mentioning the needles, curved and straight needles were used in 35 and 10, respectively. The results of our review revealed that about 80% of previous articles used Catgut and Polyglactin 910 sutures. Because no studies that compared the efficacy of different size of sutures were identified, we investigated the differences using the cases reported in previous studies mentioned above. In the first analysis, we compared the uterine preservation rate between size 1 and size 2 sutures. We found no significant difference in uterine preservation rate (92.8%: size 1 vs. 94.2%: size 2, p > 0.05) but found significant difference in transfusion rate (62.4% vs. 79.1%, p < 0.01). With the hypothesis that non-transfusion cases were less severe, we excluded these cases from second analysis. Although our second analysis of only Catgut or Polyglactin showed strong selection bias, we observed that uterine preservation rate was significantly higher in cases with size 2 suture than in those with size 1 suture (86.9% vs. 93.5%, p = 0.033). CONCLUSIONS: Our systematic review showed that approximately 80% of cases were treated by Catgut and Polyglactin 910. Due to the heterogeneity of cases included in this review, it is difficult to estimate which suture is better for UCSs. More robust studies are necessary to enable the identification of the superior suture for performing UCSs.

The role of acetylsalicylic acid (aspirin) as a chemo-preventive and adjuvant therapeutic agent for cancers is generating attention. Mounting evidence indicates that aspirin reduces the incidence and mortality of certain obesity-related cancers, particularly colorectal cancer. In endometrial cancer, previous studies examining the effect of aspirin remain inconsistent as to the reduction in the risk of endometrial cancer. While some evidence indicates protective effects in obese women, other studies have showed a potential deleterious effect of these medications on endometrial cancer outcomes. However, exposure measurement across studies has been inconsistent in recording dose, duration, and frequency of use; thus making comparisons difficult. In this article, we review the evidence for the association between endometrial cancer and obesity, the pharmacological differences between regular- and low-dose aspirin, as well as the potential anti-tumor mechanism of aspirin, supporting a possible therapeutic effect on endometrial cancer. A proposed mechanism behind decreased cancer mortality in endometrial cancer may be a result of inhibition of metastasis via platelet inactivation and possible prostaglandin E2 suppression by aspirin. Additionally, aspirin use in particular may have a secondary benefit for obesity-related comorbidities including cardiovascular disease in women with endometrial cancer. Although aspirin-related bleeding needs to be considered as a possible adverse effect, the benefits of aspirin therapy may exceed the potential risk in women with endometrial cancer. The current evidence reviewed herein has resulted in conflicting findings regarding the potential effect on endometrial cancer outcomes, thus indicating that future studies in this area are needed to resolve the effects of aspirin on endometrial cancer survival, particularly to identify specific populations that might benefit from aspirin use.

Staphylococcus aureus as a pathogen in human gestational membranes, a rather rare phenomenon, has recently been the focus of several researches. S. aureus forms biofilms on these membranes and potentially causes chorioamnionitis in pregnant women. We report a case of persistent methicillin-resistant S. aureus (MRSA) bacteremia owing to placental infection, causing chorioamnionitis and preterm birth. A 29-year-old Japanese woman at the 27th gestational week was diagnosed with acute promyelocytic leukemia and underwent all-trans retinoic acid therapy. Soon after hospitalization, the patient presented with persistent MRSA bacteremia of unknown origin. Despite various antimicrobial therapies, she experienced 12 MRSA bacteremia episodes over 6 weeks. However, after child birth, MRSA bacteremia disappeared without any complications. A pathologic examination of her placenta revealed placenta abscess, resulting in a diagnosis of MRSA-associated chorioamnionitis. Molecular analysis proved that a single MRSA strain (SCCmec Type IVa), which tested negative for Panton-Valentine leukocidin and toxic shock syndrome toxin-1, caused the obstinate infection. We should be aware that persistent MRSA bacteremia in pregnant women can originate from placental abscess.

AIM: Previous studies have shown adverse obstetric outcomes of the laparoscopic resection of a rudimentary horn. Our study aimed to investigate the obstetric outcome in our institution and to review previous studies. METHODS: Using a retrospective analysis, data were reviewed from singleton pregnancies with maternal uterine anomalies at a medical center in Osaka, Japan, between January 2011 and March 2016. The uterine anomaly cases were divided into a 'postlaparoscopic resection of the rudimentary horn' group (study group) and an 'other uterine anomalies' (bicornuate uterus, uterine didelphys and unicornuate uterus) group (control group). Primary outcomes of interest were differences in obstetric outcomes, such as spontaneous preterm birth rate, small for gestational age (SGA) infant rate and hypertensive disorders of pregnancy (HDP) rate between the study and the control group, and the secondary outcome of interest was mode of delivery in the study group. RESULTS: Data from 40 deliveries were included in the study (7 deliveries: study group, 33 deliveries: control group). No significant difference was observed between the two groups in terms of either mean gestational weeks at delivery (36.4 weeks vs 37.1 weeks; P = .38), cesarean delivery rate (57.1% vs 57.5%; P = 1.0), SGA infant rate (<10th percentile) (0% vs 24.2%; P = .31) and HDP rate (0.0% vs 3.0%; P = 1.0). Three of seven cases with postlaparoscopic resection of the rudimentary horn were able to deliver vaginally without complications. CONCLUSION: Our study shows that the obstetric outcome observed in the study group was similar to that observed in the control group.

OBJECTIVE: To examine characteristics and survival outcomes of women with apparent early-stage endometrial cancer who had a supracervical hysterectomy. METHODS: The Surveillance, Epidemiology, and End Results Program was used to identify women with presumed stage I endometrial cancer who underwent supracervical hysterectomy between 1983 and 2012. Propensity score matching was performed to adjust background difference between supracervical hysterectomy (n=1,339) and total hysterectomy (n=110,523) cases. Endometrial cancer-specific survival (CSS) was examined by multivariable analysis expressed with adjusted-hazard ratio [HR] and 95% confidence interval [CI]. RESULTS: Supracervical hysterectomy was independently associated with younger age, low-grade disease, and small tumor size on multivariable analysis (all, P<0.001). After propensity score matching, supracervical hysterectomy remained an independent prognostic factor for decreased CSS compared to total hysterectomy (10-year rates, 91.0% versus 94.9%, adjusted-HR 1.72, 95%CI 1.20-2.47, P=0.003). Among women who received postoperative radiotherapy, 10-year CSS rates were similar between supracervical and total hysterectomy cases (84.7% versus 80.3%, P=0.40). Contrary, in the absence of postoperative radiotherapy, women undergoing supracervical hysterectomy had a significantly lower 10-year CSS rate compared to those undergoing total hysterectomy (92.1% versus 97.2%, P<0.001). Moreover, with lack of lymphadenectomy, supracervical hysterectomy was associated with decreased CSS compared to those who had total hysterectomy (91.6% versus 94.3%, P=0.018) but had similar CSS rates with lymphadenectomy (92.7% versus 91.8%, P=0.91). CONCLUSION: Although rarely performed, supracervical hysterectomy is associated with decreased survival outcome among women with apparent stage I endometrial cancer supporting the importance of avoiding this procedure in women with or at risk of endometrial cancer.
