Practical diagnosis and treatment of premenstrual syndrome and premenstrual dysphoric disorder by psychiatrists and obstetricians/gynecologists in Japan. PCN REPORTS : PSYCHIATRY AND CLINICAL NEUROSCIENCES 2024; 3:e234. [PMID: 39149567 PMCID: PMC11325828 DOI: 10.1002/pcn5.234] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 06/30/2024] [Accepted: 07/28/2024] [Indexed: 08/17/2024]
Abstract
Aim To investigate and compare the diagnoses and treatment of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) from the perspectives of psychiatrists and obstetricians/gynecologists (OB/GYNs) in Japan. Methods Between December 2021 and February 2022, a web-based survey was conducted among the members of the Japanese Association of Neuro-Psychiatric Clinics. Data from 262 psychiatrists who responded to the aforementioned survey were compared with data from 409 OB/GYNs from a survey conducted in 2021 among members of the Japanese Society of Obstetrics and Gynecology. Results Overall, 79.8% of psychiatrists and 97.3% of OB/GYNs were involved in practicing PMS/PMDD diagnosis and treatment. Most psychiatrists believed that PMS should be treated by OB/GYNs (74.4%) and PMDD by psychiatrists (75.6%). Only vague medical interviews were conducted by 86.6% of psychiatrists, and only 9.7% maintained a two-cycle symptom diary. Psychiatrists mostly prescribed selective serotonin/serotonin and noradrenaline reuptake inhibitor (SSRI/SNRI) continuous dosing (91.1%), followed by Kampo medicines, especially Kamishoyosan (73.3%); only 2.8% chose oral contraceptive pills, unlike OB/GYNs, while SSRI continuous (32.8%) and luteal phase dosing (20.6%) and Kampo medicine (42.1%) were the most common first-line treatments. Lifestyle guidance was prescribed by 63.6% of psychiatrists, followed by cognitive behavioral therapy (13.8%) and the symptom diary observation method (11.1%), which were similar to OB/GYNs' choices. Conclusions Many Japanese psychiatrists and OB/GYNs do not base PMS/PMDD diagnoses on prospective monitoring methods using specific diagnostic criteria and therefore do not provide evidence-based treatment. Moreover, a tendency of being biased toward treatments in which the department specialized was observed.

Abstract
PURPOSE To evaluate differences in maternal characteristics and obstetric and offspring childhood outcomes between births at and after 37 weeks of gestation (referred to as term and post-term births) according to the use of tocolytic treatment. METHODS Data for 63,409 women with singleton births at and after 37 weeks of gestation were analyzed using data from the Japan Environment and Children's Study (JECS). We compared maternal characteristics, obstetric outcomes, and offspring childhood outcomes between term and post-term births exposed and not exposed to tocolytic treatment. Additionally, multivariable logistic regression models were used to calculate adjusted odds ratios for offspring childhood outcomes with significant between-group differences in the univariable analysis, with term and post-term births without tocolytic agents as the reference group. RESULTS We observed differences in maternal characteristics and obstetric outcomes between term and post-term births exposed and not exposed to tocolytic treatment. The incidence of offspring childhood developmental disorders showed no significant between-group differences. However, participants exposed to tocolytic agents had higher incidence of offspring childhood allergic disorders. The adjusted odds ratio for any of the offspring childhood allergic disorders in term and post-term births with tocolytic agents was 1.08 (95% confidence interval, 1.03-1.13). CONCLUSION This study found no significant difference in the incidence of offspring developmental disorders between term and post-term births exposed and not exposed to tocolytic treatment. However, tocolytic treatment was associated with differences in maternal characteristics and obstetric outcomes, along with a marginal increase in the incidence of childhood allergic disorders in offspring.

Abstract
OBJECTIVE This study aimed to evaluate the timing of elective cesarean sections at 37 to 41 weeks from a tertiary hospital in Japan. The primary outcome was the rate of adverse neonatal outcomes, especially focusing on neonates delivered at 38 weeks of gestation. STUDY DESIGN The study population was drawn from singleton pregnancies delivered following planned cesarean birth at the Fukuda Hospital from 2012 to 2019. Information on deliveries was obtained from the hospital database, which contains clinical, administrative, laboratory, and operating room databases. RESULTS After excluding women with chronic conditions, maternal complications, indications for multiple births, or a neonate with an anomaly, 2,208 neonates remained in the analysis. Among adverse neonatal outcomes, the rate was significantly higher in neonates delivered at 37 weeks of gestation (unadjusted odds ratio [OR] = 13.22 [95% confidence interval [CI]: 6.28, 27.86], p < 0.001) or 38 weeks of gestation (unadjusted OR = 1.82 [95% CI: 1.04, 3.19], p = 0.036) compared with neonates delivered at 39 to 41 weeks. The adjusted risk of any adverse outcome was significantly higher at 380-1/7 weeks (adjusted OR = 2.40 [95% CI: 1.35, 4.30], p = 0.003) and 382-3/7 weeks (adjusted OR = 1.89 [95% CI: 1.04, 3.44], p = 0.038) compared with neonates delivered at 39 to 41 weeks, respectively. CONCLUSION Our findings suggest that elective cesarean sections might be best scheduled at 39 weeks or later. When considering a cesarean at 38 weeks, it appears that 384/7 weeks of gestation or later could be a preferable timing in the context of reducing neonatal risks. However, as the composite outcome includes mostly minor conditions, the clinical significance of this finding needs to be carefully interpreted. KEY POINTS · Timing of elective cesarean sections from 37 to 41 weeks was evaluated in a Japanese tertiary hospital.. · Neonates delivered at 37 and 38 weeks had higher adverse outcome rates compared with 39 to 41 weeks.. · Scheduling elective cesarean sections at least 384/7 weeks or later may reduce neonatal risk..

Abstract
OBJECTIVES To investigate the association between adenomyosis and placenta accreta spectrum (PAS) and to evaluate the effect of assisted reproductive technology (ART) in mediating this association. METHODS We retrieved data for singleton women from the Japanese nationwide perinatal registry between 2013 and 2019, excluding women with a history of adenomyomectomy. To investigate the association between adenomyosis and PAS among women, we used a multivariable logistic regression model with multiple imputation for missing data. We evaluated mediation effect of ART including in vitro fertilization and intracytoplasmic sperm injection on the association between adenomyosis and PAS using causal mediation analysis based on the counterfactual approach. RESULTS Of 1 500 173 pregnant women, 1539 (0.10%) had adenomyosis. The number receiving ART was 489/1539 (31.8%) and 117 482/1 498 634 (7.8%) in women with and without adenomyosis, respectively. The proportion of women who developed PAS was 21/1539 (1.4%) in women with adenomyosis and 7530/1 498 634 (0.5%) in women without adenomyosis. Adenomyosis was significantly associated with PAS (odds ratio [OR] 1.95; 95% confidence interval [CI] 1.26-3.00; P = 0.002). Mediation analysis showed that OR of the total effect of adenomyosis on PAS was 1.98 (95% CI 1.13-3.04), OR of natural indirect effect (effect explained by ART) was 1.15 (95% CI 1.01-1.41), and OR of natural direct effect (effect unexplained by ART) was 1.72 (95% CI 0.86-2.82). The proportion mediated (natural indirect effect/total effect) was 26.5%. Adenomyosis was also significantly associated with PAS without previa (OR 1.96; 95% CI 1.23-3.13, P = 0.005). CONCLUSION Adenomyosis was significantly associated with PAS. ART mediated 26.5% of the association between adenomyosis and PAS.

Abstract
Premenstrual symptoms are characterized by unpleasant psychophysical symptoms that appear during the luteal phase before menstruation and interfere with a woman's quality of life. Premenstrual syndrome (PMS) is a pathological condition with premenstrual symptoms, of which premenstrual dysphoric disorder (PMDD) is a particularly severe psychological symptom. This study aimed to examine the gender differences in the diagnosis and treatment of PMS and PMDD among obstetricians and gynecologists (OB/GYNs) in Japan. Data were obtained from the survey conducted by the Japanese Society of Obstetrics and Gynecology. We used data from 1,257 of the 1,265 OB/GYNs who are engaged in PMS/PMDD practice and reported their gender. Multivariate regression analysis adjusted for propensity scores was performed. Female OB/GYNs were more frequently engaged in treating patients with PMS/PMDD than males [odds ratio (OR) 1.74; 95% confidence interval (CI) 1.36-2.21]. With regard to the diagnostic methods, more female OB/GYNs selected the two-cycle symptom diary than males (OR 2.88; 95% CI 1.80-4.60). Regarding treatment, fewer female OB/GYNs selected selective serotonin reuptake inhibitors as their first-line drug (OR 0.39; 95% CI 0.17-0.89). Gender differences were found in the selection of PMS/PMDD diagnosis and treatment methods among Japanese OB/GYNs.

Abstract
Objective To develop an evidence-based guideline for the diagnosis and treatment of antipsychotic-induced hyperprolactinemia by adapting existing high-quality clinical guidelines with a view to improve the clinical symptoms and long-term quality of life of patients by providing appropriate management. Methods This guideline was developed according to the ADAPTE methodology. The adaptation process included determining key health questions, systematically searching and screening guidelines, evaluating the quality and contents of these guidelines, deriving recommendations for key questions, and performing a peer review. The selection criteria for the guideline search were (1) evidence-based guidelines, (2) published within the last 5 years, and (3) written in English or Korean. Results After evaluating the quality and content, we finally selected three guidelines for adaptation. The final output of the development process was 25 recommendations for 10 key questions. We adopted the Agency for Health Research Quality methodology and presented the level of evidence from levels I to IV. In addition, we defined the recommendation grades from grade A (strongly recommended) to D (no recommendation) based on the level of evidence and clinical significance of the recommendation. Conclusion The development and dissemination of the adapted guideline is expected to increase the certainty of medical decision making and improve the quality of medical care. Further studies on the effectiveness and applicability of the developed guideline are necessary.

Abstract
BACKGROUND The white blood cell count is often used to assess the maternal condition after an operative vaginal delivery. However, it remains unknown whether the maternal white blood cell count on the day after delivery is associated with sequential maternal adverse outcomes, especially infectious complications. The aim of this study was to investigate the association between maternal white blood cell count on the day after operative vaginal delivery and sequential maternal adverse events. METHODS The study was a retrospective cohort study using the Medical Data Vision claims database containing administrative claims data, discharge abstracts, and laboratory values in Japan. We identified all patients who underwent operative vaginal delivery with data on maternal white blood cell count from December 2011 to November 2020. The main composite outcome was maternal adverse outcomes, comprising additional treatment for maternal injuries, postpartum intravenous antibiotic use, and intensive care unit use during hospitalization. We conducted a restricted cubic spline analysis to investigate the nonlinear association between white blood cell count and the primary outcome. RESULTS There were 485 eligible patients including 73 patients with occurrence of the primary outcome. The median (interquartile range) white blood cell count on the day after delivery in all eligible women was 15,170 (12,610-18,300)/mL. In the restricted cubic spline analysis, there was no significant association of white blood cell count with the primary outcome. CONCLUSION White blood cell count on the day after operative vaginal delivery was not significantly associated with maternal adverse outcomes during hospitalization.

Abstract
AIM To investigate the current status and problems in the diagnosis and treatment of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) from the perspective of obstetricians and gynecologists (OB/GYNs) in Japan, the Japanese Society of Obstetrics and Gynecology (JSOG) conducted a national-wide survey. METHODS An email survey was sent to all JSOG members (16 732) and a web-based survey was conducted using a Google form between September and November 2021. The current status and problems in PMS/PMDD diagnosis and treatment were surveyed in this cross-sectional study. RESULTS In total, 1312 respondents (7.8% of all JSOG members) completed the questionnaire. In terms of diagnoses and treatment, OB/GYN was preferred over psychiatrist for PMS (91.4% vs. 45%); however, no differences were noted for PMDD (76.1% vs. 73.7%). A total of 1267 (96.6%) respondents engaged in routine PMS/PMDD treatment. Regarding the general diagnosis procedure, 84.4% respondents answered "only a vague medical interview," 8.4% kept a two-cycle symptom diary, and 10.3% used a screening questionnaire. The most commonly used medication was oral contraceptive pills (OCPs) (98.1%), followed by the Kampo, traditional Japanese herbal medicines, Kamishoyosan (73.6%). Concerning first-line drugs for treatment, OCPs were the most common (76.8%), followed by Kampo medicine (19.5%); selective serotonin reuptake inhibitors (SSRIs) were less frequently used (2.6%). Regarding first-line drugs among OCPs, 65.1% respondents reported drospirenone-ethinylestradriol use. CONCLUSIONS This study indicates that only a few OB/GYNs practicing PMS/PMDD in Japan use a prospective diary, which is an essential diagnostic criterion for PMS/PMDD. Regarding treatment, SSRIs were used less frequently.

Women who test positive for the human papillomavirus (HPV) but have normal cytology constitute the predominant subgroup of patients in the screening population in the post-vaccination era. The distribution of HPV genotypes changed dramatically, which was attributable to an increase in HPV vaccination coverage. These changes have created uncertainty about how to properly manage women with normal cytology, non-HPV16/18 infections, or persistent infections. Current recommendations include retesting and continued surveillance in the absence of HPV16/18 infection. However, these are not always applicable. The ability to implement genotyping or incorporate HPV16/18 with some additional high-risk HPV (HR-HPV) types for triage and management with the aim of identifying type-specific risks in this population could be acceptable. When the next set of guidelines is updated, generating potential triage strategies for detecting high-grade cervical lesions, such as the p16/Ki67 cytology assay and other alternatives that incorporate genotyping with newer tests, should be considered. Current clinical management is shifting to risk-based strategies; however, no specific risk threshold has been established in this population. Importantly, innovative triage testing should be evaluated in combination with primary screening and management. Furthermore, there is an untapped opportunity to coordinate HPV genotyping in combination with colposcopic characteristics to modify risk in this group. Hence, providing a more personalized schedule through the efficient application of risk stratification and improving the detection of pre-cancer and cancer is an option worth exploring.

Menstrual Symptoms, Health-Related Quality of Life, and Work Productivity in Japanese Women with Dysmenorrhea Receiving Different Treatments: Prospective Observational Study. Adv Ther 2022; 39:2562-2577.

Abstract
INTRODUCTION Dysmenorrhea is a physical and mental burden for women, negatively affecting health-related quality of life (HRQL) and work productivity. However, data on HRQL and work productivity of Japanese women are scarce. METHODS In this prospective observational study, 397 Japanese women received low-dose estrogen/progestin (LEP) or non-LEP treatment (non-steroidal anti-inflammatory drugs or Chinese herbal medicines) for primary/secondary dysmenorrhea and completed survey questionnaires online regarding menstrual symptoms, HRQL, and work productivity. Regression analysis was performed to compare the groups and evaluate outcomes over time using the paired t test. Subgroup analysis was performed using stratification by patient background, and correlations between improvement in menstrual symptoms/HRQL and work productivity were investigated using Spearman's rank correlation coefficient. RESULTS Significant reductions in the modified Menstrual Distress Questionnaire (mMDQ) total score were shown in the LEP group (n = 251) (P < 0.01), but not the non-LEP group (n = 146). Significant improvements in HRQL, measured by the 36-Item Short-Form Health Survey v2.0 (SF-36v2.0), were shown in the LEP group, but not the non-LEP group. Improvements were seen in mental component summary and 7/8 domains (role physical, bodily pain, general health, role emotional, mental health, vitality, and social functioning) in the LEP group, but not the non-LEP group. There were no differences in the physical component summary and role functioning in either group. Improvements in work productivity, measured by the modified Work Productivity and Activity Impairment Questionnaire (mWPAI), were greater in the LEP group vs. non-LEP group. Regression analysis showed differences in improvements between the groups in the mMDQ total score, SF-36v2.0, and mWPAI. A correlation between mMDQ or HRQL and work productivity was seen. CONCLUSION In Japanese women, dysmenorrhea is associated with reduced HRQL and work productivity. In real-world clinical practice, improvements in physical and mental menstrual symptoms, HRQL, and work productivity were observed with LEP treatment.

Abstract
OBJECTIVE To clarify whether "low-risk total PP" patients bleed more than partial/marginal PP patients. MATERIALS AND METHODS The retrospective cohort study was performed involving patients with PP between April 2006 and December 2018. The placental position was determined by ultrasound. From medical charts, the backgrounds as well as obstetric and neonatal outcomes of PP patients were retrieved. RESULTS This study included 349 patients with PP, which was classified into three types according to the distance between the placenta and internal ostium: total (n = 174), partial (n = 52), and marginal (n = 123) PP. In total PP patients, three factors (prior CS, anterior placenta, and placental lacunae on ultrasound) significantly increased blood loss at CS, the need for hysterectomy, homologous transfusion (≥10 U), and ICU admission. No significant difference was observed in bleeding-related poor outcomes (rate of blood loss ≥2000 mL, amount of homologous transfusion, need for hysterectomy, and ICU admission) between total PP patients without all three factors: "low-risk total PP patients" and partial/marginal PP patients (19.8 vs. 17.1%; p = 0.604, 3.7 vs. 1.1%; p = 0.330, 1.2 vs. 1.1%; p = 1.000, and 1.2 vs. 1.1%; p = 1.000, respectively). CONCLUSION Prior CS, anterior placenta, and placental lacunae on ultrasound were risk factors for a bleeding-related poor outcome in total PP patients. Total PP patients without these three factors showed the same bleeding-related poor outcome as partial/marginal PP patients.

Abstract
OBJECTIVES Previous studies examining the incidence of omental metastasis in uterine serous carcinoma generally suffered from the small sample size, retrospective observational design, and single-center setting. So far, there was no systematic review and meta-analysis available on this topic, we conducted this study to quantitatively synthesize the data relating to this topic. DESIGN systematic review and meta-analysis. MATERIAL AND METHODS PubMed, Embase, and Web of Science were searched up until August 15, 2020. Two reviewers independently performed study selection, data extraction, and quality assessment. I2 was employed to assess the heterogeneity among included studies. Effect sizes along with 95% confidence intervals were calculated to analyze outcomes of interest. Funnel plots and the Egger test were used to detect the possibility of publication bias. OUTCOME MEASURES incidence of omental metastasis in uterine serous carcinoma. RESULTS A total of 16 studies involving 1012 women with uterine serous carcinoma were included in this systematic review and meta-analysis. All the included studies were at low risk of bias, and the heterogeneity among them was low. The pooled incidence of overall omental metastasis, occult omental metastasis, and gross omental metastasis in uterine serous carcinoma were 18% (95% CI, 0.15-0.20), 6% (95% CI, 0.04-0.08), and 10% (95% CI, 0.08-0.13), respectively. CONCLUSIONS Uterine serous carcinoma has a high tendency of omental metastasis. The main form of omentum involvement is gross metastasis. However, occult metastasis in the normal-looking omentum is also worthy of note.

Abstract
BACKGROUND The progression rate from CIN1 to CIN3 is 9.0% and that for invasive cancer is 1.0%. The large majority of CIN1 lesions regress spontaneously, and the treatment of CIN1 is still controversial. AIMS The aim of this study is to investigate the responsible HPV genotype in the low-grade SILs, then to predict the presence of high-grade SILs, and determine whether further treatment is needed. METHODS We use the methods of manual microdissection with FFPE tissue specimens and the E6/E7 uniplex polymerase chain reaction (PCR) to detect HPV in the lesions. RESULTS The HPV test was performed on 72 biopsy tissue specimens, and 55 (76.4%, 55/72) of them were HPV positive. Nine (16.4%, 9/55) of them escalated to CIN2 after LEEP or cervical conization, and 46 (83.6%, 46/55) were still CIN1. There were 17 (23.6%, 17/72) cases with HPV-negative results in cervical biopsy tissues. HPV test of cervical biopsy diagnosed with CIN1 has a positive predictive value of 16.4% in the presence of CIN2 or higher lesions, a negative predictive value of 94.1%, a specificity of 25.8%, and a sensitivity of 90.0%. HPV test of cervical biopsy tissues for the prediction of HPV infection in LEEP or cone surgery tissues had a positive predictive value of 80.0%, a negative predictive value of 82.3%, a specificity of 56.0%, and a sensitivity of 93.6%. CONCLUSIONS It is the first time that we have detected HPV genotype in the low-grade SILs by the methods of manual microdissection with FFPE tissue specimens and the E6/E7 uniplex PCR. Patients with cervical biopsy tissue diagnosed with CIN1 and with a negative or only low-risk HPV type result can be considered for follow-up. Conversely, in cases of cervical biopsy tissue diagnosed with CIN1 positive for high-risk HPV, surgery or a close follow-up program can be selected.

Abstract
Objectives The aims of this study were to clarify the following: (1) how often does prolonged pregnancy ≥34 weeks occur in patients with emergent cerclage without progesterone and (2) the risk factors preventing such pregnancy continuation. Materials and Methods This retrospective observational study was performed using medical records of patients for whom emergent cerclage had been performed between April 2006 and December 2018 in our institute. Results Emergent cerclage was performed in 123 patients (median age: 34, interquartile range: 31–36). Primiparous patients numbered 44 (36%). A history of spontaneous preterm birth (SPTB) was present in 30 (24%). The median presurgical cervical length (CL) was 16 (8–21) mm at surgery. Of the 123, 20 (16%) were delivered at 33 + 6 weeks or less (<34 weeks). We conducted logistic regression analysis of the risk factors of SPTBs <34 weeks after cerclage. Three risk factors were identified that increased the risk of SPTB <34 weeks: presurgical CL 0 mm (odds ratio (OR): 5.30; 95% confidence interval (CI): 1.58–17.7), a history of SPTB (OR: 4.65; 95% CI: 1.38–15.7), and the presence of sludge (OR: 4.14; 95% CI: 1.20–14.3). Conclusion Three risk factors predicted SPTB <34 weeks after emergency cerclage without progesterone administration: unmeasurable CL (CL 0 mm), a history of SPTB, and the presence of sludge on ultrasound. SPTB <34 weeks occurred after emergency cerclage in 16% of patients, being comparable with the recent data with progesterone.

Abstract
INTRODUCTION Dysmenorrhea and endometriosis are common gynecologic disorders among women of reproductive age that significantly impact health-related quality of life (HRQL) as well as productivity. Although there are treatment options listed in Japanese guidelines, a gap remains in unmet medical needs for maximizing treatment outcome. The extended regimen of ethinylestradiol and drospirenone (EE/DRSP) (taken daily for up to 120 consecutive days) has been available in Japan for treating dysmenorrhea and/or endometriosis-associated pain since 2016. Yet, the effectiveness of its usage on HRQL has not been investigated elsewhere to date. Therefore, in this study, we aim to observe changes in HRQL of Japanese women treated with an extended regimen of EE/DRSP for dysmenorrhea and/or endometriosis-associated pain. METHODS As part of a 2-year post-marketing surveillance study, women with dysmenorrhea or endometriosis-associated pelvic pain were prescribed extended EE/DRSP during routine clinical practice. Data were collected 1 month before and 3 and 6 months after initiating treatment. Primary outcomes were the Menstrual Distress Questionnaire (MDQ) (before, during, and after menstruation) in patients with dysmenorrhea, and the Endometriosis Impact Scale (EIS) and European Quality of Life 5-dimensions 5-level instrument (EQ-5D-5L) in patients with endometriosis. RESULTS The study cohort included 315 patients (mean age 28.9 years) with dysmenorrhea and 262 patients (mean age 31.3 years) with endometriosis. Mean MDQ total scores before and during menstruation decreased significantly after 6 months with extended EE/DRSP; there was no improvement in after-menstruation MDQ score. Mean EIS domain scores improved significantly by 6 months, with improvement in most EIS individual item scores. Mean EQ-5D-5L scores increased slightly during 6 months of treatment. CONCLUSIONS Extended EE/DRSP treatment improved HRQL outcomes in Japanese women with dysmenorrhea or endometriosis-associated pelvic pain.

Abstract
AIM In Japan, the criteria of the latent and active phases of the first stage of labor have not been decided. The Japan Society of Obstetrics and Gynecology (JSOG) Perinatal Committee conducted a study to construct a spontaneous labor curve in order to determine the point of onset of the active phase. METHODS The participants were women who had spontaneous deliveries at four health facilities in Japan between September 1, 2011, and September 31, 2019. Spontaneous delivery was defined as the spontaneous onset of labor at term (37 weeks, 0 days to 41 weeks, 6 days) with vaginal delivery of a mature fetus in a cephalic position without uterotonic agents or epidural analgesia. The time points for each "cm" of dilation were collected starting from the time of full dilation retrogradely. The relationship between time since labor onset and cervical dilation was expressed as a curve using a smoothing B-spline. RESULTS A total of 4215 primiparous and 5266 multiparous women were included in this study. The spontaneous labor curve showed that in both primiparous and multiparous women, labor progress was slow until 5 cm cervical dilation, accelerating between 5 and 6 cm dilation, and steadily progressed after 6 cm dilation. CONCLUSION We propose that the active phase of the first stage of labor be defined as starting at 5 cm dilation of the cervix, and that it be divided into an acceleration phase (5-6 cm dilation) and a maximal phase (>6 cm dilation).

Resuscitative efficacy of hemoglobin vesicles for severe postpartum hemorrhage in pregnant rabbits. Sci Rep 2021; 11:22367. [PMID: 34785755 PMCID: PMC8595665 DOI: 10.1038/s41598-021-01835-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Accepted: 10/27/2021] [Indexed: 11/18/2022] Open
Abstract
We aimed to investigate the resuscitative efficacy of hemoglobin vesicles (HbVs) as a red blood cell (RBC) substitute for the initial treatment of severe postpartum hemorrhage (PPH). Twenty-five pregnant rabbits underwent cesarean section; uncontrolled hemorrhage was induced by transecting the right uterine artery to establish a severe PPH model. During the first 30 min, all rabbits were administered 6% hydroxyethyl starch (HES) of an equivalent volume to the hemorrhage every 5 min. Thereafter, they received any of the following three isovolemic fluids for resuscitation every 5 min: RBCs with platelet-poor plasma (RBC/PPP) (n = 8), 6% HES (n = 7), or HbVs with 25% human serum albumin (n = 10). After surgical hemostasis at 60 min, survival was monitored until 12 h. No rabbits receiving only HES infusion survived beyond 6 h, whereas all rabbits receiving RBC/PPP transfusion survived. The rabbits receiving HbV infusion showed significantly higher mean arterial pressure and hemoglobin levels than the HES-receiving rabbits, and 8 of 10 rabbits survived for 6 h. The HbV group showed significantly higher survival than the HES group but worse survival than the RBC/PPP group. In conclusion, HbV infusion for severe PPH effectively prevents lethal hemorrhagic shock in a pregnant rabbit model.

Association between maternal ritodrine hydrochloride administration during pregnancy and childhood wheezing up to three years of age: The Japan environment and children's study. Pediatr Allergy Immunol 2021; 32:1455-1463. [PMID: 34013624 DOI: 10.1111/pai.13545] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2021] [Revised: 04/25/2021] [Accepted: 05/13/2021] [Indexed: 01/14/2023]
Abstract
BACKGROUND The effects of maternal ritodrine hydrochloride administration (MRA) during pregnancy on fetuses and offspring are not entirely clear. The present study aimed to evaluate the association between MRA and childhood wheezing using data from a nationwide Japanese birth cohort study. METHODS This study analyzed the data of the participants enrolled in the Japan Environment and Children's Study, a nationwide prospective birth cohort study, between 2011 and 2014. Data of women with singleton live births after 22 weeks of gestation were analyzed. The participants were divided according to MRA status. Considering childhood factors affecting the incidence of wheezing, including smoking environment and childhood viral infections, a logistic regression model was used to calculate odds ratios for "wheezing ever," diagnosis of asthma in the last 12 months, and "asthma ever" in women with MRA, with women who did not receive MRA as the reference. Additionally, participants were stratified by term births, and odds ratios for outcomes were calculated using a logistic regression model. RESULTS A total of 68,123 participants were analyzed. The adjusted odds ratio for wheezing was 1.17 (95% confidence interval, 1.12-1.22). The adjusted odds ratios for the other outcomes did not significantly increase after adjusting for childhood factors. The same tendency was confirmed after excluding women with preterm births. CONCLUSION MRA was associated with a slightly increased incidence of childhood wheezing up to three years, irrespective of term or preterm birth status. It is important that perinatal physicians consider the potential effects of MRA on the offspring's childhood health.

BJOG 2021; 129:805-811. [PMID: 34545675 DOI: 10.1111/1471-0528.16938] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 08/11/2021] [Accepted: 09/12/2021] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Pregnant women may develop disseminated intravascular coagulation (DIC), possibly resulting in massive maternal haemorrhage and perinatal death. The Japan guideline recommends use of antithrombin III (ATIII) for DIC in obstetrics; however, its effect remains uncertain. The present study aimed to investigate the effect of ATIII for DIC in obstetrics, using a national inpatient database in Japan. DESIGN Nationwide observational study. SETTING Japan. POPULATION We used the Diagnosis Procedure Combination inpatient database to identify patients who delivered at hospital and were diagnosed with DIC from July 2010 to March 2018. METHODS Propensity score matching analyses were performed to compare in-hospital maternal mortality and hysterectomy during hospitalisation between users and non-users of ATIII on the day of delivery. MAIN OUTCOME MEASURES In-hospital mortality, hysterectomy. RESULTS A total of 9920 patients were enrolled, including 4329 patients (44%) who used ATIII and 5511 patients (56%) who did not use ATIII. One-to-one propensity score matching created 3290 pairs. In-hospital maternal mortality did not differ significantly between the propensity-matched groups (0.3% in the ATIII group versus 0.5% in the control group; odds ratio 0.73; 95% CI 0.35-1.54). A significantly lower proportion of patients in the ATIII group, compared with those in the control group, underwent hysterectomy during hospitalisation (5.3% versus 8.7%; absolute risk difference -2.9%; 95% CI -4.2 to -1.6%). CONCLUSIONS Although the present study did not show a mortality-reducing effect of ATIII for patients with DIC in obstetrics, it may have clinical benefit in terms of reducing the number of patients undergoing hysterectomy. TWEETABLE ABSTRACT This study did not show mortality-reducing effect of antithrombin III for patients with DIC in obstetrics.

Abstract
BACKGROUND Screening-based intrapartum antibiotic prophylaxis (IAP) has reduced the prevalence of early-onset group B Streptococcus (GBS) infection in newborns. Nevertheless, early-onset disease still occurs despite IAP, and IAP is not effective in preventing late-onset disease. This study aimed to determine the prevalence and risk factors of GBS neonatal umbilical colonization managed by dry cord care in Japan. METHODS Of 735 healthy newborns in the well-baby nursery at Saitama City Hospital, 353 from whom umbilical bacterial swabs were obtained before discharge were included in the analysis. Maternal and neonatal clinical characteristics were retrospectively reviewed. RESULTS GBS was detected in 4.2% (15/353) of umbilical swabs; 13/15 (86.8%) were born to GBS-negative mothers. The median (IQR) age at umbilical swab collection was 4.0 (4.0-5.0) days. Comparison of clinical characteristics between GBS-positive and negative neonates revealed a significant difference in the proportion of vaginal deliveries (15/15 [100%] in GBS-positive neonates vs. 115/338 [34.0%] in GBS-negative neonates, p < 0.0001). Of 15 GBS-positive neonates, 10 (66.7%) were also co-colonized with other enteric bacteria such as Escherichia coli. CONCLUSION Vaginal delivery was a risk factor associated with GBS neonatal umbilical colonization in Japanese neonates. Co-colonization with multiple enteric bacterial species implicates vertical transmission of GBS from undetected carrier mothers during passage through the birth canal.

Abstract
OBJECTIVES Guidelines that include antimicrobial recommendations should explicitly consider contextual factors that influence antimicrobial resistance and their downstream effects on resistance selection. The objectives were to analyse (1) how, and to what extent, tuberculosis, gonorrhoea and respiratory tract infection guidelines are considering antimicrobial resistance; (2) are of acceptable quality and (3) if they can be easily contextualised to fit the needs of specific populations and health systems. METHODS We conducted a systematic review and searched Ovid MEDLINE and Embase from 1 January 2007 to 7 June 2019 for tuberculosis, gonorrhoea and respiratory tract infection guidelines published in English. We also searched guideline databases, key websites and reference lists. We identified guidelines and recommendations that considered contextual factors including antimicrobial resistance, values, resource use, equity, acceptability and feasibility. We assessed quality of the guidelines using the Appraisal of Guidelines for Research and Evaluation II tool focusing on the domains scope and purpose, rigour of development, and editorial independence. RESULTS We screened 10 365 records, of which 74 guidelines met inclusion criteria. Of these guidelines, 39% (n=29/74) met acceptable quality scores. Approximately two-thirds of recommendations considered antimicrobial resistance at the population and/or outcome level. Five of the 29 guidelines reported all factors required for recommendation contextualisation. Equity was the least considered across guidelines. DISCUSSION Relatively few guidelines for highly prevalent infectious diseases are considering resistance at a local level, and many do not consider contextual factors necessary for appropriate antimicrobial use. Improving the quality of guidelines targeting specific regional areas is required. PROSPERO REGISTRATION NUMBER CRD42020145235.

Abstract
INTRODUCTION In Japan, universal screening for group B streptococcal (GBS) colonization in pregnant women and intrapartum antibiotic prophylaxis (IAP) are recommended to prevent neonatal GBS infection. However, the dynamics of GBS colonization in Japanese mother/neonate pairs have not been adequately studied. METHODS A prospective cohort study was conducted from July 2018 to March 2019. Rectovaginal samples were collected from pregnant women (33-37 gestation weeks) once. In neonates, nasopharyngeal and rectal samples were collected at three time points: after birth, 1 week after birth, and 1 month after birth. All samples were analyzed for GBS using real-time PCR testing and culture methods. Capsular typing was performed for all GBS isolates and GBS-positive samples using real-time PCR testing. RESULTS The overall maternal and neonatal GBS-positivity rates were 22.7% (57/251) and 8.8% (22/251), respectively. IAP for GBS-positive mothers (96.5%) was highly administered. Eleven (19.3%) neonates born to GBS-positive mothers were GBS-positive, which was significantly higher than the 11 (5.7%) neonates born to GBS-negative mothers. The rate of GBS-positivity in neonates increased with an increased number of GBS colonies in mothers. More neonates were GBS-positive 1 month after birth than 1 week after birth, and there was a higher rate of GBS-positive rectal swabs than nasopharyngeal swabs. Capsular types of GBS that were isolated from each mother and neonate pair were the same, namely, Ib, III, V, and VI. CONCLUSIONS These findings indicate that the efficacy of IAP in preventing GBS transmission to neonates might be limited to within a few weeks after birth.

Abstract
Objectives Magnetic resonance (MR) R2 relaxometry is a safe, noninvasive diagnostic modality for the evaluation of iron levels in the contents of ovarian cysts. The study aims to investigate the sensitivity and specificity of the two methods, R2 value and iron level, in diagnosing OMA patients in the validation set. Methods A prospective cohort study was conducted from 2013 to 2019. We investigated how R2 value was affected by iron-related compounds, antioxidants and bioelements in the cysts. Results The sensitivity and specificity of CF iron-based diagnosis of OMA was 96.6% and 95.4%, respectively. The sensitivity and specificity for R2 value in diagnosing OMA were 86.2% and 70.7%, respectively. The outcomes of the two tests were highly correlated (r = 0.758; P <0.001). The R2 value was positively correlated with CF levels of iron-related compounds and antioxidants. The R2 value was affected not only by iron ions but also by calcium ions. Conclusion Preoperative MR relaxometry may provide a noninvasive alternative to CF iron test in diagnosing OMA. The presence of paramagnetic cations in the cyst may be associated with reduced specificity.

Abstract
We present herein a rare case of uterine serous carcinoma with mesonephric-like differentiation (SC-MLD) initially misdiagnosed as mesonephric-like adenocarcinoma (MLA). A 51-year-old woman underwent total hysterectomy for a uterine tumor. Histologically, the tumor exhibited various architectures, including papillary, glandular, tubular, cribriform, and cystic. On the basis of this architectural diversity accompanied by intraluminal eosinophilic secretions and intermediate-grade nuclear atypia, the initial diagnosis was MLA. However, the tumor was diffusely and strongly positive for the expression of p16 and negative for the expression of GATA-binding protein 3 (GATA3). Furthermore, we identified a pathogenic tumor protein 53 (TP53) mutation affecting an acceptor splice site in intron 9, despite a wild-type p53 immunostaining pattern. The observations of diffuse and strong p16 expression, lack of GATA3 expression, pathogenic TP53 mutation, and wild-type Kirsten rat sarcoma viral oncogene homolog indicate that this tumor was not an MLA but an SC-MLD. Both uterine SC and MLA can exhibit various histological growth patterns. Our comprehensive clinicopathological and molecular analyses can serve to improve the understanding of this rare condition and help pathologists in making an accurate diagnosis.

Abstract
BACKGROUND Recent studies have focused on the role of oxidative stress, which may be implicated in the development, progression, and pathophysiology of endometriosis. AIM OF THE STUDY The aim of this study is to investigate the redox balance of endometriosis by simultaneously measuring iron-related compounds (total iron, heme iron, free iron, oxyhemoglobin [oxyHb], methemoglobin [metHb] and 8-hydroxy-2-deoxy guanosine [8-OHdG]) and antioxidants (bilirubin, heme oxygenase-1 [HO-1] and total antioxidant capacity [TAC]). METHODS This study includes 236 histopathologically confirmed cases (178 cases of endometriosis and 58 cases of non-endometriosis). Cyst fluid samples were collected from patients admitted to the Department of Gynecology, Nara Medical University, Kashihara, Japan, for surgery. RESULTS Age at diagnosis (p <0.001), the maximum diameter of the cyst (p <0.001) and CA125 levels (p <0.001) differed significantly between the two groups. Total iron, heme iron, free iron, metHb, and oxyHb were markedly higher in endometriosis compared to non-endometriosis. Bilirubin, HO-1 and TAC were significantly higher in endometriosis patients compared with those from non-endometriosis patients. In endometriosis, total iron showed a positive correlation with HO-1 (r, 0.518, p = 0.001), but there were no antioxidants that correlated with iron in non-endometriosis. Iron and HO-1 did not correlate with age or tumor size. CONCLUSIONS HO-1 may regulate the delicate balance of iron-induced oxidative stress in endometriotic cyst fluid.

Abstract
AIM In 2010, the Japan Society of Obstetrics and Gynecology (JSOG) changed the diagnostic criteria for gestational diabetes mellitus (GDM) to follow the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria. As a result, many pregnant women with mildly impaired glucose tolerance (IGT) were newly diagnosed with GDM. This study aimed to verify the effects of interventions in pregnant women with mild IGT who were newly diagnosed with GDM based on the present JSOG criteria. METHODS We defined mild IGT as a degree of IGT that would be diagnosed as GDM according to the present but not the previous JSOG criteria. We compared pregnancy and delivery outcomes in women with mild IGT who delivered a singleton at 22 weeks of gestation or later, between 2000 and 2009 (untreated group, n = 503) versus between 2011 and 2017 (treated group, n = 781). RESULTS The incidence of GDM-related composite complications such as macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, and neonatal respiratory distress syndrome was comparable in the untreated and treated groups (10.1% vs. 11.9%, p = 0.11). The pregnancy outcomes were also comparable, except for infant birth weights, which were lower in the treated group than in the untreated group (3014 g vs. 3094 g; p = 0.02). CONCLUSIONS Pregnancy outcomes were not affected by the interventions in pregnant women with mild IGT.

Shindo R, Aoki S, Nakanishi S, Misumi T, Miyagi E. Impact of gestational diabetes mellitus diagnosed during the third trimester on pregnancy outcomes: a case-control study. BMC Pregnancy Childbirth 2021; 21:246. [PMID: 33761893 PMCID: PMC7992332 DOI: 10.1186/s12884-021-03730-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 03/17/2021] [Indexed: 12/16/2022] Open
Abstract
Background In 2010, the International Association of Diabetes and Pregnancy Study Group (IADPSG) proposed new criteria indicating that gestational diabetes mellitus (GDM) can be diagnosed if the fasting threshold of ≤92 mg/dL, 1-h threshold of ≤180 mg/dL, or 2-h threshold of ≤153 mg/dL are exceeded during the 75-g 2-h oral glucose tolerance test (OGTT) performed at 24–28 weeks of gestation. The World Health Organization (WHO) recommends using the proposed diagnostic threshold values of the IADPSG to diagnose GDM; however, it does not limit the timing of the 75-g OGTT. Since 2010 in Japan, GDM has been diagnosed using the same criteria as that proposed by the WHO. However, neither the JSOG nor the WHO has provided any evidence that it is appropriate to use a threshold beyond the range recommended by the IADPSG. Methods This was a single-centre retrospective study based on the medical records and delivery registry database of our centre. We included women who underwent a 50-g glucose challenge test (GCT) with results < 140 mg/dL at 24–28 weeks of gestation and subsequently underwent a 75-g OGTT after 29 weeks of gestation with abnormal glucose tolerance suspected based on clinical findings. The reference values for the 75-g OGTT followed the IADPSG criteria. Subjects were classified into the normal glucose tolerance (NGT) group and the GDM group. The type of delivery and neonatal outcomes of the two groups were compared. A multivariable analysis was performed to match the backgrounds of both groups. Results In total, the NGT and GDM group comprised 189 and 49 women, respectively. Emergency caesarean delivery rates were similar in the GDM and NGT groups (10.6 and 12.2%, respectively; adjusted odds ratio [OR], 1.25; 95% confidence interval [CI], 0.43–3.64; p = 0.74); however, the elective caesarean delivery rate was higher in the GDM group than in the NGT group (16.3 and 5.3%, respectively, adjusted OR, 3.60; 95% CI, 1.27–10.19; p = 0.01). No significant differences were observed in other maternal and neonatal outcomes between both groups. Conclusion Although a diagnosis of GDM during the third trimester does not improve pregnancy outcomes, it increases the elective caesarean delivery rate.

Abstract
OBJECTIVE To clarify the natural history of retained products of conception (RPOC) following abortion at less than 22 weeks of gestation, and those who show major bleeding during course observation. STUDY DESIGN We retrospectively reviewed 640 patients who had spontaneous or artificial abortion at less than 22 weeks of gestation between January 2011 and August 2019 in our institute. Of those, patients with RPOC were included. The maternal background, RPOC characteristics, and subsequent complications including additional interventions were reviewed. RESULTS Fifty-four patients with RPOC were included. The incidence of RPOC was 6.7 %. The median (interquartile range: IQR) RPOC length was 29 (20-38) mm. RPOC hypervascularity was observed in 26 (48 %) patients. The median (IQR) periods of RPOC flow disappearance and RPOC disappearance on ultrasound from abortive treatment were 50 (28-76) and 84 (50-111) days, respectively. Of the 54, 44 patients were selected for expectant management. Of the 44, 34 (77 %) patients were observed without intervention (recovery group); the other 10 (23 %) patients required additional interventions associated with subsequent bleeding (intervention group). Compared with the recovery group, heavy bleeding (> 500 mL) at abortion (6/10: 60 %) and RPOC hypervascularity (8/10: 80 %) were more frequently observed in the intervention group. CONCLUSION Expectant management was successful in almost 80 % of patients with RPOC following abortion. The additional interventions were required in patients with heavy bleeding at abortion and RPOC hypervascularity.

Abstract
INTRODUCTION Uterine serous carcinoma accounts for only about 10% of all endometrial cancers but this subtype is the most common amongst non-endometrioid endometrium cancers and contributes to more than half of recurrence and deaths attributed to endometrial cancers. A more extensive surgical staging and adjuvant therapies for uterine serous carcinoma are recommended by many guidelines. However, guidelines vary on recommendations for the methods that should be used for omentum assessment in uterine serous carcinoma and the previously reported incidence of omental metastasis in uterine serous carcinoma had a wide range because of the heterogeneity among these studies. As far as we know, there are no systematic review and meta-analysis available on this topic. The aim of our proposed study is to statistically synthesise the data examining the incidence of omental metastasis in uterine serous carcinoma. METHODS AND ANALYSIS Systematic searches of three databases (PubMed, Embase and Web of Science) will be performed using prespecified search strategies. We will include original studies that reported incidence of omental metastasis in uterine serous carcinoma and are published before 30 August 2020. Our different investigators will independently conduct the eligible study selection, assess the quality of included studies and extract the needed data. If appropriate, the relevant data will be pooled through a random-effect or fixed-effect meta-analysis based on the heterogeneity among included studies. We will evaluate the overall quality of evidence using appropriate methods. ETHICS AND DISSEMINATION This proposed study will be based on published data, and thus, there is no requirement for ethics approval. We aim to publish the results of this study in a peer-reviewed journal with good visibility for the fields of gynaecology and gynecologic oncology. PROSPERO REGISTRATION NUMBER CRD42020200891.

Abstract
In Japan, uterine cancer screening during pregnancy is subsidized by public funds. We examined the current status of the results of cervical cytology conducted during pregnancy in Japan. We requested 2,293 obstetrical facilities to provide information on cervical cytology in pregnant women who delivered between October 2018 and March 2019. A total of 1,292 obstetrical facilities responded, with valid information on a total of 238,743 women. The implementation rate of cervical cytology during pregnancy was 86.8% in Japan. The prevalence of abnormal cervical cytology during pregnancy was 3.3% in total and 4.9% using a spatula/brush with liquid-based cytology (LBC). The prevalence of positive high-risk human papillomavirus (HPV) in teenagers with atypical squamous cells of undetermined significance (ASC-US) was significantly higher than women of other ages (p < 0.01). Because HPV vaccine coverage has dropped to less than 1% in Japan, a further study with various conditions will be needed to improve the accuracy of cervical cancer screening during pregnancy.

Abstract
OBJECTIVE The aim of the study was to examine whether high-grade cervical intraepithelial neoplasia (CIN) was more closely associated with human papillomavirus (HPV) same-genotype persistence (SGTP) versus clearance of prior infection with a subsequent infection by a new genotype (genotype switch [GS]), clearance of HPV infection, or acquisition of a new HPV infection after a negative infection status, during a follow-up testing subsequent to abnormal screening results. MATERIALS AND METHODS MEDLINE, Cochrane Library, Health Technology Assessment, and clinicaltrials.gov were searched from January 2000 to July 2019 for prospective controlled trials and observational studies of women and retrospective studies using HPV assays with extended- or full-genotype reporting. The primary outcome was high-grade CIN after at least 2 rounds of testing. Overall quality of evidence for the risk estimate outcomes was assessed. Of the 830 identified abstracts, 66 full-text articles were reviewed, and 7 studies were included in the synthesis. The study protocol was registered with the PROSPERO International Prospective Register of Systematic Reviews (CRD42018091093). RESULTS Continued HPV-positive women falls in 2 equally large groups: SGTP and GS. Sensitivity, positive predictive value, and positive likelihood ratio of SGTP were significantly higher than for GS. Human papillomavirus genotypes may be ranked into 3 tiers (immediate colposcopy, follow-up testing, return to routine screening), according to associated risk of persistence for high-grade CIN and to prevailing clinical action thresholds. CONCLUSIONS There is moderately high-quality evidence to support the clinical utility of SGTP to improve risk discrimination for high-grade CIN compared with qualitative HPV testing without genotype-specific information.

Abstract
AIM To investigate the effectiveness of 10% povidone-iodine formulation as a vaginal irrigation agent in patients undergoing hysterectomy to prevent postoperative infection. METHODS The prevalence of postoperative infection in 277 and 132 patients who underwent preoperative vaginal cleaning with 500 mL of distilled water and 20 mL of 10% povidone-iodine solution, respectively, were compared in this retrospective study. RESULTS Postoperative infection was observed in 15.6% of the overall patient population. The rate of postoperative infection was significantly higher in patients treated with 10% povidone-iodine formulation than in those treated with distilled water (21.4% vs 12.8%, P = 0.040). Besides the agents of vaginal irrigation, operation time, length of hospital stay and rate of intraoperative complications affected the prevalence of postoperative infection. The multivariate analysis ranked the use of 10% povidone-iodine formulation for vaginal irrigation as the second top factor contributing to postoperative infection (relative risk: 1.9 when compared to distilled water). CONCLUSION Preoperative vaginal irrigation with 10% povidone-iodine formulation led to a significantly higher rate of postoperative infection than did preoperative vaginal irrigation with distilled water. For vaginal irrigation with povidone-iodine, different concentrations and cleaning methods should be considered in the future.

Abstract
Objective This study aimed to examine the associations of cone margin and human papillomavirus (HPV) status after conization with cytological abnormalities and disease recurrence in patients with cervical intraepithelial neoplasia grade 3 (CIN3). Methods This is a retrospective study of 366 women with CIN3 who underwent conization at Kagoshima University Hospital between 2004 and 2017. Conization was performed using an ultrasonic scalpel. The polymerase chain reaction for detecting HPV genotypes was performed using fresh cervical cell samples. We examined the associations of margin status and HPV status after conization with cytological abnormalities and recurrence. Results Among 224 women with CIN3, 193 (86.2%) underwent HPV genotype testing before conization. The HPV-positive rate was 84.9%. The most common HPV genotypes before conization were HPV 16, 31, 58, 52, 18, 35, and 33. In 191 patients, the uterus was preserved after conization. Sixteen patients had pathologically positive margins, 165 had negative margins, and 10 had unclear margins. There was no significant difference in abnormal cytology and recurrence rate after conization between the three groups. Five patients with positive margins and abnormal cytology during follow-ups were HPV16- or HPV58-positive in the preoperative HPV testing. Of the 191 women, 91 (47.6%) underwent pre- and postoperative HPV genotype testing, among whom 14 (15.4%) were HPV-positive after conization. No significant difference in abnormal cytology based on HPV status after conization was found. The recurrence rate tended to be higher in HPV-positive patients than in HPV-negative patients after conization (21.4% vs. 1.3%, p < 0.05). Three patients with HPV positivity after conization and recurrence during follow-up were HPV16- or HPV58-positive. Conclusions HPV positivity after conization for CIN3 was associated with a high recurrence rate, especially in HPV16- and HPV58-positive patients. HPV58 has not received much attention thus far, but abnormalities in cytology and recurrence may be as likely as those associated with HPV16. Thus, a careful follow-up in such patients is recommended.

Abstract
Abstract
Aim
As a result of the 2012–2013 rubella epidemics in Japan, many cases of congenital rubella syndrome have been reported. Given the frequent changes to rubella vaccination policy in Japan, we investigated antibody prevalence among pregnant women according to birth year.
Subjects and methods
Participants comprised 55,400 pregnant Japanese women for whom rubella-specific hemagglutination inhibition antibody had been measured during early pregnancy in our institute from 1987 to 2016. Birth year was considered for the 47,978 cases for which age was known.
Results
The ratio of rubella antibody-negative cases among pregnant women born after 1962 decreased significantly with mandatory vaccination. In the transition phase, during which the administration target was changed from schoolgirls to children of both sexes (born 1979–1987) as temporary vaccination, the ratio of rubella antibody-negative pregnant women started increasing in the latter period of this phase. For generations born in or after 1988, the ratio of rubella antibody-negative pregnant women clearly increased when the vaccination target changed to non-mandatory vaccination of children of both sexes.
Conclusions
Prevalence of antibody titers depends on vaccine coverage rates. Suitable information needs to be provided prior to conception to all women, their husbands, and family members.

Abstract
Endometrial cysts (ECs) are thought to be the origin of endometriosis-associated ovarian cancer (EAOC). A hypothesis that the oxidative stress of iron in cysts causes “malignant transformation of ECs” has been proposed, but this has not been verified. Several population-based studies showed that endometriosis was a risk factor but did not reflect the “malignant transformation of ECs”. A review showed that most patients were diagnosed with EAOC early in monitoring following detection of ECs, and that these cases might have been cancer from the start. Epidemiologically, EAOC was reduced by hysterectomy rather than by cystectomy of ECs. Gene mutation analyses identified oncogenic mutations in endometriosis and normal endometrium and revealed that the same mutations were present at different endometriotic lesions. It was also shown that most of the gene mutations found in endometriosis occurred in normal endometrium. Taking together, EAOC might be caused by eutopic endometrial glandular epithelial cells with oncogenic mutations that have undergone menstrual blood reflux and engrafted in the ovary, rather than by low-risk ECs acquiring oncogenic mutations and becoming malignant. This review discusses the mechanisms of EAOC development and targeted therapy based on genetic variation in EAOC with a focus on eutopic endometrium.

Abstract
INTRODUCTION Endometriosis is a common benign gynecological condition that can be associated with a slightly increased risk of developing a wide range of malignancies. CASE PRESENTATION We herein report a singular case of a 62-year-old woman with a history of pelvic endometriosis, referred to our institution for chronic pelvic pain and uterine bleeding, with clinical and radiological evidence of left ovarian mass of 18 cm in largest diameter and multiple nodular mural lesions of the uterine cavity. The patient underwent exploratory laparotomy followed by hysterectomy, bilateral salpingo-oophorectomy, and omentectomy with pelvic lymph-node sampling. The histological examination of the ovarian mass revealed a clear-cell ovarian carcinoma arising from an endometriotic cyst. The microscopic examination of the uterine cavity showed multiple conventional leiomyomas, diffuse foci of adenomyosis, and a 1.5-cm yellow nodule diagnosed as low-grade endometrial stromal sarcoma associated with glandular atypical differentiation and with extension into parametrial and omental tissues. Following the diagnosis, the patient was treated with chemotherapy, radiation therapy, and hormonal therapy and after 9 months of follow-up is alive without local recurrences and distant metastases. DISCUSSION/CONCLUSIONS To the best of our knowledge, the present case represents the first evidence of the simultaneous occurrence of clear-cell carcinoma and low-grade endometrial stromal sarcoma arising within ovarian and uterine endometriotic foci, respectively.

Human papillomavirus genotype contribution to cervical cancer and precancer: Implications for screening and vaccination in Japan. Cancer Sci 2020; 111:2546-2557. [PMID: 32372453 PMCID: PMC7385338 DOI: 10.1111/cas.14445] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 04/29/2020] [Accepted: 04/30/2020] [Indexed: 12/24/2022] Open
Abstract
To obtain baseline data for cervical cancer prevention in Japan, we analyzed human papillomavirus (HPV) data from 5045 Japanese women aged less than 40 years and diagnosed with cervical abnormalities at 21 hospitals during 2012‐2017. These included cervical intraepithelial neoplasia grade 1 (CIN1, n = 573), CIN2‐3 (n = 3219), adenocarcinoma in situ (AIS, n = 123), and invasive cervical cancer (ICC, n = 1130). The Roche Linear Array was used for HPV genotyping. The HPV type‐specific relative contributions (RCs) were estimated by adding multiple infections to single types in accordance with proportional weighting attributions. Based on the comparison of type‐specific RCs between CIN1 and CIN2‐3/AIS/ICC (CIN2+), RC ratios were calculated to estimate type‐specific risks for progression to CIN2+. Human papillomavirus DNA was detected in 85.5% of CIN1, 95.7% of CIN2‐3/AIS, and 91.2% of ICC. Multiple infections decreased with disease severity: 42.9% in CIN1, 40.4% in CIN2‐3/AIS, and 23.7% in ICC (P < .0001). The relative risk for progression to CIN2+ was highest for HPV16 (RC ratio 3.78, 95% confidence interval [CI] 3.01‐4.98), followed by HPV31 (2.51, 1.54‐5.24), HPV18 (2.43, 1.59‐4.32), HPV35 (1.56, 0.43‐8.36), HPV33 (1.01, 0.49‐3.31), HPV52 (0.99, 0.76‐1.33), and HPV58 (0.97, 0.75‐1.32). The relative risk of disease progression was 1.87 (95% CI, 1.71‐2.05) for HPV16/18/31/33/35/45/52/58, but only 0.17 (95% CI, 0.14‐0.22) for HPV39/51/56/59/66/68. Human papillomavirus 16/18/31/33/45/52/58/6/11 included in a 9‐valent vaccine contributed to 89.7% (95% CI, 88.7‐90.7) of CIN2‐3/AIS and 93.8% (95% CI, 92.4‐95.3) of ICC. In conclusion, our data support the Japanese guidelines that recommend discriminating HPV16/18/31/33/35/45/52/58 genotypes for CIN management. The 9‐valent vaccine is estimated to provide over 90% protection against ICC in young Japanese women.

Abstract
Background The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study was launched in 2013 to evaluate the complex interactions of genetic and environmental factors in multifactorial diseases. The present study describes the maternal baseline profile and perinatal data of participating mothers and infants. Methods Expectant mothers living in Miyagi Prefecture were recruited from obstetric facilities or affiliated centers between 2013 and 2017. Three sets of self-administered questionnaires were collected, and the medical records were reviewed to obtain precise information about each antenatal visit and each delivery. Biospecimens, including blood, urine, umbilical cord blood, and breast milk, were collected for the study biobank. The baseline maternal sociodemographic characteristics, results of screening tests, and obstetric outcomes were analyzed according to the maternal age group. Results A total of 23,406 pregnancies involving 23,730 fetuses resulted in 23,143 live births. Younger maternal participants had a tendency toward a higher incidence of threatened abortion and threatened premature labor, while older age groups exhibited a significantly higher rate of low lying placenta, placenta previa, gestational diabetes, and hypertensive disorders of pregnancy. Conclusions The present study clearly shows the distribution of maternal baseline characteristics and the range of perinatal outcomes according to maternal age group. This cohort study can provide strategic information for creating breakthroughs in the pathophysiology of perinatal, developmental, and noncommunicable diseases by collaborative data visiting or sharing.

Abstract
PURPOSE Analgesic medication epidemic during pregnancy is an important issue in Western countries. However, no large epidemiological study involving pregnant women with pain and their medication use has been conducted in Japan. This study examined the current situation of medication use for non-cancer pain during the perinatal period in Japan using national cohort data. METHODS We analyzed 94,649 pregnant women who completed a self-report questionnaire investigating bodily pain and an interview-based medication use survey. Medication use before and during pregnancy and new medication administration/discontinuation during pregnancy were compared between women with and without pain during pregnancy using multivariable covariance analysis. RESULTS Mild pain was reported by 50.4% of pregnant women in the first trimester (survey 1) and 61.8% in the second/third trimester (survey 2). Moderate-to-severe pain was reported by 15.4% of women in survey 1 and 22.4% in survey 2. In survey 1, 6.2% of women used prescribed analgesics and 1.6% used over-the-counter analgesics. In survey 2, prescribed and over the counter analgesics were used by 12.2% and 0.8% of women, respectively. Other pain-related medications were rarely used (< 1.0%). Pregnant women with moderate-to-severe pain showed a lower proportion of discontinuation of analgesics and a higher proportion of new administration of prescription and transdermal analgesics compared with those without pain. CONCLUSIONS Although a large proportion of pregnant women experience pain, medication use for pain during pregnancy is low in Japan compared with Western countries (50-60%). Adequate treatment or support may be necessary for pregnant women experiencing pain in Japan.

Abstract
Purpose: To evaluate the effectiveness and safety of tadalafil treatment for hypertensive disorder of pregnancy (HDP).Materials and methods: In an open-label, randomized clinical trial, singleton pregnancies with HDP between 20 and 33 weeks of gestation were randomized to take 20 mg oral tadalafil every day (tadalafil treatment group) or no drug (conventional treatment group). The primary outcome was prolongation of pregnancy from randomization to delivery. However, this article primarily focuses on the safety assessments performed in the tadalafil treatment for HDP population, because the safety of using PDE5 inhibitors as therapeutic agents for fetal growth restriction (FGR) has been a problem worldwide.Results: From October 2016 to March 2018, 28 patients were randomized to each group and two cases were excluded (tadalafil treatment group: 12 cases; conventional treatment group: 14 cases). The significant adverse events related to tadalafil did not occur in the tadalafil treatment group. Among maternal adverse events, specifically with regard to headaches, there were significant differences between the two groups (0% in tadalafil group versus 43% in conventional treatment group; p = .02). There was no difference in the prolongation period of pregnancy that served as primary outcomes in both the groups (17.5 d in tadalafil group versus 16.5 d in conventional group, p = .96). The significant adverse events occurred at the same frequency as between the conventional treatment group and the tadalafil treatment group. And, maternal headache decreased significantly in the tadalafil treatment group.Conclusions: Tadalafil treatment is safe for pregnant women with HDP. Moreover, tadalafil did not prolong the gestational period in pregnant women with HDP.

Abstract
The Japanese government began a human papillomavirus (HPV) vaccination program for girls aged 12‐16 years in 2010 but withdrew its recommendation in 2013 because of potential adverse effects, leading to drastically reduced vaccination uptake. To evaluate population‐level effects of HPV vaccination, women younger than 40 years of age newly diagnosed with cervical intraepithelial neoplasia grade 1‐3 (CIN1‐3), adenocarcinoma in situ (AIS), or invasive cervical cancer (ICC) have been registered at 21 participating institutes each year since 2012. A total of 7709 women were registered during 2012‐2017, of which 5045 were HPV genotyped. Declining trends in prevalence of vaccine types HPV16 and HPV18 during a 6‐year period were observed in CIN1 (50.0% to 0.0%, Ptrend < .0001) and CIN2‐3/AIS (83.3% to 45.0%, Ptrend = .07) only among women younger than 25 years of age. Overall, HPV vaccination reduced the proportion of HPV16/18‐attributable CIN2‐3/AIS from 47.7% to 33.0% (P = .003): from 43.5% to 12.5% as routine vaccination (P = .08) and from 47.8% to 36.7% as catch‐up vaccination (P = .04). The HPV16/18 prevalence in CIN2‐3/AIS cases was significantly reduced among female individuals who received their first vaccination at age 20 years or younger (P = .02). We could not evaluate vaccination effects on ICC owing to low incidence of ICC among women aged less than 25 years. We found HPV vaccination to be effective in protecting against HPV16/18‐positive CIN/AIS in Japan; however, our data did not support catch‐up vaccination for women older than 20 years. Older adolescents who skipped routine vaccination due to the government’s suspension of its vaccine recommendation could benefit from receiving catch‐up vaccination before age 20 years.

Abstract
BACKGROUND Redesigning electronic medical record (EMR) systems is needed to improve their usability and usefulness. Similar to other artifacts, EMR systems can evolve with time and exhibit situated roles. Situated roles refer to the ways in which a system is appropriated by its users, that is, the unintended ways the users engage with, relate to, and perceive the system in its context of use. These situated roles are usually unknown to the designers as they emerge and evolve as a response by the users to a contextual need or constraint. Understanding the system's situated roles can expose the unarticulated needs of the users and enable redesign opportunities. OBJECTIVE This study aimed to find EMR redesign opportunities by understanding the situated roles of EMR systems in prenatal care settings. METHODS We conducted a field-based observational study at a Japanese prenatal care clinic. We observed 3 obstetricians and 6 midwives providing prenatal care to 37 pregnant women. We looked at how the EMR system is used during the checkups. We analyzed the observational data following a thematic analysis approach and identified the situated roles of the EMR system. Finally, we administered a survey to 5 obstetricians and 10 midwives to validate our results and understand the attitudes of the prenatal care staff regarding the situated roles of the EMR system. RESULTS We identified 10 distinct situated roles that EMR systems play in prenatal care settings. Among them, 4 roles were regarded as favorable as most users wanted to experience them more frequently, and 4 roles were regarded as unfavorable as most users wanted to experience them less frequently; 2 ambivalent roles highlighted the providers' reluctance to document sensitive psychosocial information in the EMR and their use of the EMR system as an accomplice to pause communication during the checkups. To improve the usability and usefulness of EMR systems, designers can amplify the favorable roles and minimize the unfavorable roles. Our results also showed that obstetricians and midwives may have different experiences, wants, and priorities regarding the use of the EMR system. CONCLUSIONS Currently, EMR systems are mainly viewed as tools that support the clinical workflow. Redesigning EMR systems is needed to amplify their roles as communication support tools. Our results provided multiple EMR redesign opportunities to improve the usability and usefulness of EMR systems in prenatal care. Designers can use the results to guide their EMR redesign activities and align them with the users' wants and priorities. The biggest challenge is to redesign EMR systems in a way that amplifies their favorable roles for all the stakeholders concurrently.
