RESUMO
Retained products of conception (RPOC) is a condition in which trophoblastic tissue remains in the uterus after pregnancy, causing massive hemorrhage in some cases. Though RPOC is commonly treated by intrauterine curettage or hysteroscopic resection uterine artery embolization or hysterectomy may be performed in case of massive bleeding. We experienced two cases of RPOC after surgery for missed abortion that failed to respond to conservative treatment and required surgical treatment. They were treated by hysteroscopic resection with temporary balloon catheter occlusion of bilateral internal iliac arteries for fertility preservation. After the balloon catheters were inflated, the reduction of blood flow to RPOC was observed under transvaginal ultrasound. In both cases, good visualization was maintained throughout the surgery with minimal bleeding. They were discharged the next day and resumed menstruation 1 month after surgery. This paper demonstrates the usefulness of this procedure as a minimally invasive and fertility-preserving surgery.

Syphilis infection during pregnancy causes perinatal complications and mother-to-child transmission if untreated. A newborn was delivered by emergent cesarean section due to non-reassuring fetal status at 34 weeks of gestation. The mother tested negative for rapid plasma reagin (RPR) and Treponema pallidum hemagglutination (TPHA) in early pregnancy. The newborn had a severe inflammatory reaction, thrombocytopenia, and elevated IgM as well as disseminated intravascular coagulation and multiple organ failure. The 16S ribosomal RNA gene sequence analysis of the amniotic fluid detected Treponema pallidum. The newborn tested positive for RPR, TPHA, and IgM fluorescent treponemal antibody-absorption in the blood, and thus, congenital syphilis was diagnosed. This is the first case that 16S ribosomal RNA gene sequencing of the amniotic fluid led to an early diagnosis of congenital syphilis in a newborn. The 16S rRNA gene sequencing may be a useful method for the early detection of the primary causative microbe of congenital infection.

Purpose: It is unknown whether surgery for endometriosis or recurrence of endometriosis affects obstetric outcomes. Methods: A total of 208 pregnant women with a history of endometriosis were analyzed. Patients who had endometriomas >3 cm and no history of laparoscopic surgery for endometriosis were defined as non-surgery group (n = 60), while those who had a history of surgery for endometriosis (n = 148) were defined as surgery group. We investigated the obstetric outcomes in 208 patients according to with or without postoperative recurrence of endometriosis and the time from surgery to pregnancy. Results: Among 177 cases of on-going pregnancy, in surgery group, there were lower prevalence of placenta previa compared with non-surgery group (8.5% vs. 23.4%; p = 0.020). Subgroup analysis revealed a decreased prevalence of placenta previa in postoperative non-recurrence group (6.0%: p = 0.007) compared with non-surgery (23.4%) and postoperative recurrence group (28.6%). Placenta previa was more prevalent in the patients who got pregnant more than 2 years after surgery (20.0%) than the patients who got pregnant within 2 years (2.4%: p = 0.002). Multivariate analysis revealed that the surgery was associated with a reduction in placenta previa (OR: 0.32, 95% CI [0.11-0.90]; p = 0.032). Conclusions: Pregnancy within two years after laparoscopic surgery for endometriosis may reduce placenta previa.
RESUMO
AIM: Postlaparoscopic shoulder pain (SP), mainly caused by pneumoperitoneum with CO2 , sometimes suffers patients. This study was aimed to analyze the backgrounds of SP after gynecologic laparoscopy to clarify the risk of SP. METHODS: We analyzed answers of questionnaire about the degree of SP from 696 patients undergoing gynecologic laparoscopic surgery since 2014-2018. The questionnaire asks the degree of SP with numeric rating scale from 0 to 10, before and 3 days after operation. We defined cases in which postoperative score elevated more than three compared to preoperative score as SP(+). Analyzed backgrounds were age, parity, body mass index, operative method, operative duration and amount of hemorrhage. Statistics was performed by Fisher exact analysis as univariate analysis, and with logistic regression as multivariate analysis. All laparoscopic surgeries were performed under 10-12 mmHg in pressure of pneumoperitoneum with CO2 . RESULTS: Univariate analysis revealed categories 'less than 50 years old', and 'over 2 h' and 'over 3 h' in operative duration resulted significant high rate of SP(+). For these three factors, multivariate analysis resulted that "less than 50 years old' and 'over 3 h in operative duration' were significantly high. CONCLUSION: This study suggests that 'less than 50 years' old and 'over 3 h in operative duration' were risk factors of postlaparoscopic SP. To protect from SP after laparoscopy, some countermeasures should be necessary especially for these patients.

This systematic review aimed to investigate complications related to initial trocar insertion among 3 different laparoscopic techniques: Veress needle (VN) entry, direct trocar entry (DTE), and open entry (OE). A literature search was completed, and complications were assessed. Major vessel injury, gastrointestinal injury, and solid organ injury were defined as major complications. Minor complications were defined as subcutaneous emphysema, extraperitoneal insufflation, omental emphysema, trocar site bleeding, and trocar site infection. Arm-based network meta-analyses were performed to identify the differences in complications among the 3 techniques. Seventeen studies were included in the quantitative analysis. DTE resulted in fewer major complications when compared with VN entry although the difference was not significant (pâ¯=â¯.23) as well as significantly fewer minor complications (p < .001). There were no significant differences in minor complications when comparing OE and DTE (pâ¯=â¯.74). Fewer major complications were observed with OE compared with VN entry although the difference was not significant (pâ¯=â¯.31). There were significantly fewer minor complications for patients who underwent OE (pâ¯=â¯.01). DTE patients experienced the least number of minor complications followed by VN entry and OE. In conclusion, major complications are extremely rare, and all 3 insertion methods can be performed without mortality.

AIM: It is commonly thought that laparoscopic surgery leads to faster postoperative recovery for its low invasiveness. We evaluated postoperative quality of life (QOL) after laparoscopic myomectomy (LM) by using the Euro-QOL 5 dimension (EQ-5D) score and analyzed its relationship to surgical factors. METHODS: Between 2014 and 2016, 541 patients underwent LM at our institution. We included 86 patients in the final analysis (16% response rate) who replied to the EQ-5D questionnaire, in order to investigate postoperative QOL. We evaluated patients' EQ-5D score before the operation and on the 3rd, 7th, 14th, 21st and 28th postoperative day (POD). We investigated the degree of correlation between the EQ-5D score and four surgical characteristics (operation time, intraoperative bleeding, number of resected myomas and weight of specimen). We examined correlation between EQ-5D scores and chief complaints such as hypermenorrhea, dysmenorrhea, other pain, myoma enlargement, palpable tumor and desire for childbearing. We also examined correlation between EQ-5D scores and other factors such as patient's age, infertility, history of abdominal surgery, marriage and body mass index. RESULTS: Full recovery, defined as an EQ-5D score of 1.0, was reported 2.3% of patients by POD3, 18.6% by POD7, 58.1% by POD14, 73.3% by POD21 and 86.0% by POD28. Longer duration of operation correlated weakly with poor recovery on POD3. Intraoperative bleeding, number of resected myomas and weight of the specimen did not significantly influence EQ-5D score. There was no correlation between chief complaints or other factors mentioned above and EQ-5D score. CONCLUSIONS: More than a half of the patients undergoing LM included in our study reported full recovery of QOL after 2 weeks. The time to recover QOL was slightly influenced by the operation time. However, when LM was finished without any complications, postoperative QOL eventually seemed to improve regardless of the surgical characteristics such as operation time, intraoperative bleeding, number of resected myomas and weight of specimen.

STUDY OBJECTIVE: To evaluate a new magnetic resonance imaging (MRI) grading system for preoperative differentiation between benign and variant-type uterine leiomyomas including smooth muscle tumors of uncertain malignant potential (STUMPs). DESIGN: Retrospective analysis (Canadian Task Force classification III). SETTING: Teaching hospital (Teine Keijinkai Hospital). PATIENTS: Three-hundred thirteen patient medical records were retrospectively reviewed if treated for uterine myomas and diagnosed with variant type leiomyomas or STUMPs (n = 27) or benign, typical leiomyomas (n = 286) and treated between January 2012 and December 2014. INTERVENTION: Uterine myoma classifications using MRI findings according to a 5-grade system (grades I-V) based on 3 elements. MEASUREMENTS AND MAIN RESULTS: Uterine myoma MRI classifications were based on 3 elements: T2-weighted imaging (high or low), diffusion-weighted imaging (high or low), and apparent diffusion coefficient values (high or low; apparent diffusion coefficient < 1.5 × 10-3 mm2/sec was considered low). Grades I to II were designated as typical or benign leiomyomas, grade III as degenerated leiomyomas, and grades IV to V as variant type leiomyomas or STUMPs. Accuracy levels were 98.9%, 100%, 94.3%, 58.8%, and 41.9% for grades I through V lesions, respectively. The grades were divided into 2 groups to discriminate benign leiomyomas and STUMPs (grades I-III were considered negative and grades IV-V positive). Grades IV to V scored 85.2% for sensitivity, 91.3% for specificity, 47.9% positive predictive value, 98.5% negative predictive value, a 9.745 positive likelihood ratio, and a .162 negative likelihood ratio. CONCLUSION: This novel MRI grading system for uterine myomas may be beneficial in differentiating benign leiomyomas from STUMPs or variant type leiomyomas and could be a future effective presurgical assessment tool.

Surgical strategies for the treatment of uterine artery pseudoaneurysm (UAP) include transarterial embolization and ultrasound-guided low-dose thrombin injection. Such strategies, however, have limitations and include the risk of ischemic damage to the uterus. We report a case of UAP treated with a new hysteroscopic and laparoscopic technique. A 29-year-old G1P0 woman with spontaneous abortion was transferred to the present institution because of hemorrhagic shock. We diagnosed ruptured UAP on transvaginal ultrasound with color Doppler. Emergency laparoscopic temporary clamping of the bilateral uterine arteries was done to reduce the bleeding, and transcervical resection to stop the hemorrhaging and to collect the pseudoaneurysm tissue. After surgery, blood flow to the myometrium was monitored on ultrasound. By postoperative day 48, normal menstruation had restarted, and no intrauterine adhesions were observed. On pathology of the UAP, a dilated spiral artery without its characteristic elastic fibers was identified. This surgical approach may help preserve fertility and allow for pathological diagnosis of UAP.

The aim of this study was to evaluate whether chronic endometritis (CE) and uterine endometrium microbiota were associated with repeated implantation failures (RIFs) and recurrent pregnancy losses (RPLs). In this prospective study, uterine endometrial specimens were obtained from 24 women with RIF, 27 with RPL, and 29 fertile control women. Immunohistochemical staining of CD138 for CE and 16S ribosomal RNA (rRNA) sequencing analysis for uterine endometrium microbiota were performed simultaneously. To assess CE, Liu's method, McQueen scores and plasma cell count/10 mm2 were used. The frequency of CE (plasma cells > 5.15/10 mm2) was higher in women with RPL (29.6%) than in fertile controls (6.8%, p < 0.05). The plasma cell count/10 mm2 in women with RPL (median 1.53, range 0-252.6, p < 0.01) and women with RIF (median 0.6, range 0-6.98, p < 0.05) was higher than in fertile controls (median 0, range 0-29). The uterine endometrium microbiota in women with RPL or RIF was not significantly different from that in fertile controls. However, the relative dominance rate of Lactobacillus iners (median 4.7%, range 0-99.9 vs. median 0%, range 0-100, p < 0.001) and the positive rate of Ureaplasma species (36.3% vs. 8.6%, p < 0.05) were higher in 11 women with CE than in 69 women without CE. The results suggest that CE may be involved in the pathophysiology of RPL and RIF. Lactobacillus iners and Ureaplasma species may be associated with the etiology of CE.
RESUMO
To evaluate whether anti-ß2-Glycoprotein I/HLA-DR (anti-ß2GPI/HLA-DR) antibody is associated with pathophysiology of infertility, 224 women with infertility were enrolled from July 2020 to December 2021 in this prospective study. The serum levels of anti-ß2GPI/HLA-DR antibody (normal < 73.3 U) were determined in 224 women with infertility. Backgrounds, causes and clinical factors were compared between women with and without anti-ß2GPI/HLA-DR antibody. Forty (17.9 %) of the 224 women tested positive for anti-ß2GPI/HLA-DR antibody. The prevalence of endometriosis was higher in women with anti-ß2GPI/HLA-DR antibody than in women without the antibody (32.5 %, 13/40 vs. 17.4 %, 32/184; P = 0.048). Logistic regression analyses revealed that, among clinical factors and diseases, endometriosis was associated with anti-ß2GPI/HLA-DR antibody positivity in infertile women (adjusted-odds ratio [OR] 3.01, 95 % confidence interval [CI] 1.30-6.99; P = 0.010). Twenty-three (15.5 %) of 148 women who underwent assisted reproductive technology (ART) tested positive for anti-ß2GPI/HLA-DR antibody. The prevalence of recurrent implantation failure (RIF) defined as three or more implantation failures following in vitro fertilization and embryo transfers was higher in women with ART who tested positive for the antibody (43.5 %, 10/23) than in women with ART who tested negative (20.8 %, 26/125; P = 0.032). Logistic regression analyses revealed that RIF was associated with anti-ß2GPI/HLA-DR antibody positivity in women with ART (adjusted-OR 2.92, 95 % CI 1.05-8.11; P = 0.040). Anti-ß2GPI/HLA-DR antibody may be associated with the pathophysiology of infertility, endometriosis and RIF; and can be a potential therapeutic target in infertility.

Objectives: The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes. Materials and Methods: The retrospective cohort study included 43 pregnant cases with adenomyosis who did not undergo laparoscopic surgery before pregnancy (nonsurgery group; 26 cases) and did (surgery group; 17 cases). To evaluate the impact of surgery on perinatal outcomes, nine obstetric complications including preterm delivery, hypertensive disorder of pregnancy, placental malposition, oligohydramnios, gestational diabetes mellitus, uterine rupture, abruptio placentae, and postpartum hemorrhage were selected. One obstetric complication was counted as one point (Maximum 9 points for one person). The obstetrical morbidity was compared by adding up the number of relevant events (0-9) between the two groups. Apgar score, umbilical artery pH (UApH), neonatal intensive care unit (NICU) admission, and neonatal death were also examined. Results: The surgery group had a significantly lower prevalence of fetal growth restriction compared to the nonsurgery group (nonsurgery vs. surgery; 26.9%, 7/26 vs. 0%, 0/17: P = 0.031). No differences were found in the morbidity of the nine obstetric complications (19.2%, 45/234 vs. 13.7%, 21/153), gestational weeks (mean ± standard deviation, 37.2 ± 2.4 vs. 36.4 ± 3.2), birth weight (2573.6 ± 557.9 vs. 2555.4 ± 680.8 g), Apgar score (1, 5 min; 8.0 ± 0.7 vs. 7.7 ± 1.2, 8.9 ± 0.6 vs. 8.5 ± 1.8), UApH (7.28 ± 0.08 vs. 7.28 ± 0.06), NICU admission (26.9%, 7/26 vs. 41.2%, 7/17), and neonatal death (0%, 0%) between both groups. Conclusion: Laparoscopic adenomyomectomy may not increase obstetric complications, although attention must be paid to uterine rupture during pregnancy.
RESUMO
Objectives: Prepregnancy myomectomy is effective for the treatment of infertility or prevention of obstetric complications and is usually performed with laparoscopy. However, pregnancies following myomectomy have risks of obstetric complications, especially in cases with uterine cavity breaches, but the evidence remains unclear. We investigated how uterine cavity breach in laparoscopic myomectomy influenced the occurrence of obstetric complications. Patients and Methods: One hundred and eighty women who underwent a cesarean section from 2014 to 2020 in pregnancies following laparoscopic myomectomy were included. They were divided into two groups: 25 women in the uterine cavity breach group and 155 in the nonbreach group. Obstetric complications, including placenta accreta spectrum (PAS), uterine rupture, placental malposition, abruption placenta, preterm delivery, threatened premature labor, premature rupture of membranes, and massive intrapartum hemorrhage, were assessed. Results: Multivariate analysis revealed that the frequency of PAS in the breach group (24.0%) was statistically significantly higher than in the nonbreach group (5.2%, P < 0.05). Conclusion: This study demonstrated that women who experienced uterine cavity breach in laparoscopic myomectomy had an increased risk of PAS in subsequent pregnancies.
RESUMO
BACKGROUND: Milk-derived microRNAs (miRNAs), including hsa-miR-148a-3p (miR-148a) and hsa-miR-125b-5p (miR-125b), have been shown to be beneficial to the gastrointestinal function in infants. Here, we investigated their expression during lactation in humans and determined whether the infant formulae available in Japan contain these miRNAs. METHODS: Healthy Japanese women (n = 16) who gave birth vaginally or by cesarean section at the Teine Keijinkai Hospital between 1 September 2020, and 31 April 2021 were included in this study. Breast milk was collected by nurses on days 4 or 5 after delivery (hereinafter, transition milk) and on day 30 of postpartum (hereinafter, mature milk). The levels of miR-148a and miR-125b in breastmilk and six commercially available infant formulae were compared and evaluated using quantitative reverse transcription-polymerase chain reaction. RESULTS: In all participants, the miR-148a level in mature breastmilk was significantly lower than that in the transition milk. The changes in miR-125b expression during lactation showed similar trends to the changes in miR-148a expression. The miR-148a and miR-125b levels in all analyzed infant formulae were lower than 1/500th and 1/100th of those in mature breastmilk, respectively. CONCLUSIONS: The levels of both miR-148a and miR-125b in human breast milk decreased on day 30 postpartum compared with those in the transition milk. Additionally, the expression of these miRNAs in infant formulae available in Japan was very low. Further studies with larger populations are required to understand precisely the lactational changes in the expression of miR148a and miR-125b in breast milk.

BACKGROUND & AIMS: Milk-derived miR-148a-3p (miR-148a), which is abundant in breast milk, has been shown to be associated with the development of infants' intestines. Although it is well known that stress during lactation changes milk constituents in terms of lipid and protein, no studies have examined the influence of stress on miR-148a expression in breast milk. The objective of this study is to investigate the relationship between stress and miR-148a expression in milk, and to evaluate whether the changes in milk-derived miR-148a expression-caused by the mother's exposure to stress-influence intestinal ZO-1 expression in infants. METHODS: The participants of this study were healthy Japanese women who were nursing. Psychological stress evaluation of the subjects was conducted using a short form of the Profile of Mood State Second Edition-Adult (POMS-2). Additionally, miR-148a expressions in restraint stressed nursing mice were investigated using quantitative real-time PCR. The levels of a tight junction protein zonula occludens-1 (ZO-1) and DNA methyltransferase 1 (DNMT1), which is a direct target of miR-148a, in ileum in neonatal mice breastfed by stressed nursing mice were investigated using Western blot. Furthermore, to investigate the influence of miR-148a on ZO-1 expression within the intestine, the levels of ZO-1 and DNMT1 in human intestinal epithelial Caco-2 cells with lentivirus-mediated miR-148a overexpression were evaluated. RESULTS: A significantly negative correlation was observed between relative miR-148a expression in breast milk and the total mood disturbance T-score. Each T-score on negative mood subscales of anger-hostility, confusion-bewilderment, depression-dejection, fatigue-inertia, and tension-anxiety was significantly negatively correlated with relative miR-148a expression in breast milk: a positive mood subscale vigor-activity T-score was significantly positively correlated with relative miR-148a expression in breast milk. A positive mood friendliness T-score, estimated separately from other scores, was significantly positively correlated with relative miR-148a expression in breast milk. Additionally, the relative expression of miR-148a in the milk obtained from stressed mice was significantly lower than that of control mice. The relative level of ZO-1 in ileum of neonatal mice nursed by stressed mice was significantly lower than that of neonatal mice nursed by control mice. Additionally, the relative level of DNMT1 in ileum of neonatal mice nursed by stressed mice was significantly higher than that of neonatal mice nursed by control mice. Furthermore, the relative level of ZO-1 in miR-148a-overexpressed Caco-2 cells was significantly higher than that in control cells. The relative level of DNMT1 in miR-148a-overexpressed Caco-2 cells was significantly lower than that in control cells. CONCLUSIONS: Mothers' exposure to stress during lactation may cause miR-148a expression in breast milk. Additionally, stressed-induced suppression of miR-148a expression in breast milk may cause a decrease in intestinal ZO-1 level via the increase in DNMT1 in infants' intestines. These observations are beneficial information for breastfeeding mothers and their families and perinatal medical professionals. Our findings encourage monitoring maternal psychological stress during lactation to promote breastfeeding and adequate infant nutrition.

INTRODUCTION: We investigated whether temporary bilateral laparoscopic uterine artery clipping with hysteroscopic transcervical resection (LUA clipping-TCR) is an effective minimally invasive treatment for the management of cervical pregnancy. MATERIALS AND METHODS: This study is a retrospective clinical case series conducted at Teine Keijinkai Hospital from January 2014 to June 2019. Nine cervical pregnancies among 164 ectopic pregnancies were retrospectively examined. The intervention involved performing LUA clipping-TCR on villous tissue. Information on patient characteristics, clinical data, and surgical details was collected from medical records and surgical videos. RESULTS: The mean (range) age of the patients was 33 years (29-41 years); and mean gestational sac diameter, 12.8 mm (5-24 mm). Five patients had a history of intrauterine procedures. Three patients had a positive fetal heartbeat. The mean (range) preoperative serum hCG level (mIU/mL), surgical time (min), uterine artery blocking time (min), and amount of surgical blood loss (ml) were 14,040 (2880-41,367), 82 (62-120), 42 (21-68), and 57 (10-200), respectively. The mean decrease in serum hCG level (second postoperative day) and duration until resumption of menstruation were 79.7 % (70-86.7 %) and 46 days (35-80 days), respectively. The hospitalization period was 2-3 days, with no evidence of persistent ectopic pregnancy. Live birth was achieved in four cases. DISCUSSION: Our results confirm previous findings and provide new evidence that LUA clipping-TCR is effective for cervical pregnancy management and fertility preservation, respectively. Future large-scale prospective studies to compare different cervical pregnancy management methods are required.

INTRODUCTION: Although various perinatal complications have been reported to be increased in the pregnant patients with adenomyosis, it is not clear what type of patients with adenomyosis is more likely to cause obstetric complications. In this study, we focused on the positional relationship between the placenta and adenomyosis lesion in evaluating perinatal prognosis of pregnant patients with adenomyosis. MATERIAL AND METHODS: This retrospective cohort study was carried out between 1 January 2005 and 31 December 2019 in a single institution. Adenomyosis was diagnosed by magnetic resonance imaging (MRI) and/or transvaginal ultrasonography (TVUS). To evaluate the influence of adenomyosis on perinatal outcomes, we classified the positional relationship between the placenta and the adenomyosis lesion into two groups and examined the perinatal prognosis of the patients with adenomyosis by analyzing their clinical records. Group I (n = 9) was defined when the placenta was not overlaid on adenomyosis lesion. Group II (n = 11) was defined when a part of the placenta was overlaid on adenomyosis lesion. RESULTS: Twenty pregnant patients with adenomyosis were analyzed. There were no differences in clinical backgrounds between group I and group II. There was a significant increase in the obstetric morbidity in group II than that of Group I(group I: 6.3%, 4/63 vs group II: 18.6%, 26/77; P < 0.001). In group II, fetal growth restriction (FGR) was more frequent (0%, 0/9 vs 45.5%, 5/11; P = 0.042) and the birth weight was significantly lower than that in group I (2951.1 g ± 326.5 g vs 2318.9 ± 656.1 g; P = 0.037). There was a trend of lighter weight of the placenta in group II (550.6 ± 66.5 g vs 437.5 ± 117.8 g; P = 0.063) and the volume of bleeding during delivery was a higher trend in group II than that in group I (845.1 ± 367.1 g vs 1356 ± 604.8 g; P = 0.083). Group II was furtherly subdivided into group IIa (less than half the major axis of the placenta overlaid on adenomyosis lesion) and group IIb (more than half the major axis of placenta overlaid on adenomyosis lesion). The obstetric morbidity tended to be higher in group IIb than in group IIa (group IIa: 22.9%, 8/35 vs group IIb: 42.9%, 18/42); P = 0.09). In group IIb, the frequency of FGR was significantly higher (group IIa: 0%, 0/5 vs IIb: 83.3%, 5/6; P = 0.020) and the birth weight was significantly lower than those in group IIa (2656.8 ± 231.9 g vs 2037 ± 780.1 g; P = 0.040). All cases of FGR, hypertensive disorder of pregnancy (HDP), and oligohydramnios were observed in group IIb. CONCLUSION: Placental localization near adenomyosis may increase the risk of perinatal complications.

In endometriosis, M2 MΦs are dominant in endometriotic lesions, but the actual role of M2 MΦ is unclear. CD206 positive (+) MΦ is classified in one of M2 type MΦs and are known to produce cytokines and chemokines. In the present study, we used CD206 diphtheria toxin receptor mice, which enable to deplete CD206+ cells with diphtheria toxin (DT) in an endometriosis mouse model. The depletion of CD206+ MΦ decreased the total weight of endometriotic-like lesions significantly (p < 0.05). In the endometriotic-like lesions in the DT group, a lower proliferation of endometriotic cells and the decrease of angiogenesis were observed. In the lesions, the mRNA levels of VEGFA and TGFß1, angiogenic factors, in the DT group significantly decreased to approximately 50% and 30% of control, respectively. Immunohistochemical study revealed the expressions of VEGFA and an endothelial cell marker CD31 in lesions of the DT group, were dim compared to those in control. Also, the number of TGFß1 expressing MΦ was significantly reduced compared to control. These data suggest that CD206+ MΦ promotes the formation of endometriotic-like lesions by inducing angiogenesis around the lesions.

Objective: To determine whether an antepartum educational leaflet distributed to parents before infant delivery affected the rate of infant car-seat (ICS) use 1 month after delivery, because to the best of our knowledge, only few reports have evaluated systematic attempts to improve the rate of always ICS use by mothers driving infantsMethods: A multicenter questionnaire survey targeting pregnant Japanese women seeking antenatal care at the outpatient clinics of eight hospitals was designed. Women enrolled during the first half of the study period did not receive leaflets describing ICS safety guidelines (control group). Women enrolled during the latter half of the study period received the leaflet between gestational week 35 and 37 (intervention group). All women were requested to anonymously respond to the questionnaires within 1 month postpartum. The rates of ICS use, position, and direction after delivery were compared between both groups.Results: Of the 3534 women who responded to the questionnaire survey (response rate, 81.9%), 1772 women (50.1%) were assigned to the intervention group and 1762 (49.9%) women to the control group. The rates of ICS attachments (86.8% vs. 82.4% in the intervention and control groups, respectively, p = 0.0003), always ICS use (80.5% vs. 76.2%, respectively, p = 0.0019), ICS placement on the rear seat (78.6% vs. 74.1%, respectively, p = 0.0020), and ICS placement in a rear-facing position (62.2% vs. 56.7%, respectively, p = 0.0008) were significantly higher in the intervention group than those in the control group. The motor vehicle accident (MVA) rates within 1 month postpartum were similar between the intervention and control groups (0.51% vs. 0.57%, respectively, p = 0.8229).Conclusions: Antepartum minimal intervention via the distribution of an educational leaflet recommending ICS safety guidelines was associated with increased rates of ICS attachments, always ICS use, and ICS placement on the rear seat and in rear-facing positions; however, it did not contribute to reduced MVA rates after delivery.

BACKGROUND: Relaxin (RLX)-2, produced by the corpus luteum and placenta, is known to be potentially effective in fibrotic diseases of the heart, lungs, kidneys, and bladder; however, its effectiveness in endometriosis has not yet been investigated. In the present study, we conducted a comprehensive study on the effect of RLX-2 on endometriosis. We checked the expressions of LGR-7, a primary receptor of RLX-2, in endometriomas using immunohistochemistry. Endometriotic stromal cells (ESCs) purified from surgical specimens were used in in vitro experiments. The effects of RLX-2 on ESCs were evaluated by quantitative-PCR, ELISA, and Western blotting. Gel contraction assay was used to assess the contraction suppressive effect of RLX-2. The effect of RLX-2 was also examined in the endometriosis mouse model. LGR-7 was expressed in endometriotic lesions. In ESCs, RLX-2 increased the production of cAMP and suppressed the secretion of interleukin-8, an inflammatory cytokine, by 15% and mRNA expression of fibrosis-related molecules, plasminogen activator inhibitor-1 (PAI-1), and collagen-I by approximately 50% (p < 0.05). In the gel contraction assay, RLX-2 significantly suppressed the contraction of ESCs, which was cancelled by removing RLX-2 from the medium or by adding H89, a Protein Kinase A (PKA) inhibitor. In ESCs stimulated with RLX-2, p38 MAPK phosphorylation was significantly suppressed. In the endometriosis mouse model, administration of RLX-2 significantly decreased the area of the endometriotic-like lesion with decreasing fibrotic component compared to non-treated control (p = 0.01). RLX-2 may contribute to the control of endometriotic lesion by suppressing fibrosis, scar formation, and inflammation.
