RESUMO
Polypectomy during pregnancy is known to be a risk for spontaneous late miscarriage or preterm delivery. We managed a pregnant woman in her 30s with a large cervical polyp without polypectomy, and we administered probiotics including Clostridium butyricum and 17-alpha-hydroxyprogesterone caproate. As a result, she delivered a healthy baby at 38 weeks.

AIM: This study aimed to investigate the current status of progestogen treatment for pregnant women at a high risk for preterm birth (PTB) in childbirth healthcare facilities in Japan. METHODS: A web-based nationwide questionnaire survey regarding progestogen use for prevention of PTB was conducted among childbirth healthcare facilities from 2019 to 2021. RESULTS: Valid responses were obtained from 528 facilities (25.2% of those surveyed), including 155 tertiary perinatal facilities (making up 92.3% of all tertiary perinatal care facilities). In the survey period, progestogen treatment was implemented in 207 facilities (39.2%) for PTB prevention. Regarding types of progestogens, 17α-hydroxyprogesterone caproate was used in 170 facilities (82.1%), with a low dose (125 mg/week) administered in 62.9% of the facilities to comply with the regulations of the national health insurance system, although 250 mg/week is considered the best dose. Vaginal progesterone was used in 36 facilities (17.4%), although the cost of vaginal progesterone was not covered by health insurance. Of the facilities not administering progestogen treatment, approximately 40% expressed that vaginal progesterone would be their first choice for PTB prevention in daily practice if it would be covered by health insurance in the future. CONCLUSIONS: Due to the current regulations of the Japanese health insurance system, 17α-hydroxyprogesterone caproate, rather than vaginal progesterone, was mainly used for PTB prevention. Despite global evidence supporting vaginal progesterone as the approach with the highest efficacy, only a limited number of facilities have utilized it due to the current drug use regulations in Japan.

Autophagy is a fundamental process involved in regulating cellular homeostasis. Autophagy has been classically discovered as a cellular process that degrades cytoplasmic components non-selectively to produce energy. Over the past few decades, this process has been shown to work in energy production, as well as in the reduction of excessive proteins, damaged organelles, and membrane trafficking. It contributes to many human diseases, such as neurodegenerative diseases, carcinogenesis, diabetes mellitus, development, longevity, and reproduction. In this review, we provide important information for interpreting results related to autophagic experiments and present the role of autophagy in this field.
RESUMO
Inhibition of autophagy contributes to the pathophysiology of preeclampsia. Although chloroquine (CHQ) is an autophagy inhibitor, it can reduce the occurrence of preeclampsia in women with systemic lupus erythematosus. To clarify this important clinical question, this study aimed to address the safety of CHQ in trophoblast cells from the viewpoint of homeostasis, in which the anti-oxidative stress (OS) response and autophagy are involved. We used Western blotting to evaluate the protein levels in the trophoblast cells. The expression levels of heme oxygenase-1 (HO-1), an anti-OS enzyme, mediate resistance to OS induced by hydrogen peroxide (H2O2) in trophoblast cell lines. Among the autophagy modulators, bafilomycin A1 (BAF), an autophagy inhibitor, but not autophagy activators, suppressed HO-1 expression in BeWo cells; CHQ did not suppress HO-1 expression in BeWo cells. To clarify the role of autophagy in HO-1 induction, we observed no difference in HO-1 induction by H2O2 between autophagy-normal and autophagy-deficient cells. As for the mechanism of HO-1 induction by OS, BAF suppressed HO-1 induction by downregulating the expression of neighbor of BRCA1 gene 1 (NBR1) in the selective p62-NBR1-nuclear factor erythroid 2-related factor 2 (Nrf2) autophagy pathway. CHQ did not inhibit HO-1 expression by sustaining NBR1 expression in human villous tissues compared to BAF treatment. In conclusion, CHQ is a safer medicine than BAF for sustaining NBR1, which resist against OS in trophoblasts by connecting selective autophagy and the anti-OS response.

Fetal antigen-specific tolerance is important for maintaining allogeneic pregnancies. Maternal conventional T cells recognize fetal antigens; however, regulatory T (Treg) cells suppress immune reactions against the fetus. Fetal antigen-specific Treg cells are induced in the decidua upon contact with antigen-presenting cells and extravillous trophoblasts (EVTs). Functional alteration of cytotoxic T cells (CTLs) in the decidua also contributes to maintaining the pregnancy. Reduced, dysfunctional, and imbalanced Treg cell distribution likely contributes to the pathogenesis of pregnancy complications, such as miscarriage and preeclampsia. Recent studies have revealed differences in Treg cell characteristics during preeclampsia and miscarriage. Treg cell reduction in the decidua is likely associated with miscarriage. Insufficient expansion of fetal antigen-specific Treg cells in the decidua probably plays a role in preeclampsia pathogenesis. In addition, the balance between Treg cell-mediated tolerance and functional alteration of CTLs is important. Further investigations of functional molecules in Treg cells will contribute to the development of immunotherapy for pregnancy complications.

BACKGROUND AND AIM: Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare neoplasm, and its clinical features and management are still limited. We evaluated the clinicopathological factors, including CDX2 immunohistochemical expression, to predict survival in patients with LCNEC. PATIENTS AND METHODS: In all, 50 patients with LCNEC who underwent surgery at 4 institutes between 2001 and 2017 were included. Clinicopathological characteristics were evaluated for prognostic factors and statistically analyzed by Kaplan-Meier curve with a log-rank test or Cox regression models. We used immunohistochemical (IHC) analysis to determine the expressions of CDX2 and compared them with clinicopathological factors and survival. RESULTS: Sixteen of the 50 cases (32%) were CDX2 positive. No correlation was found between the CDX2 expression by IHC and clinicopathological factors. Multivariate analysis identified adjuvant chemotherapy (hazard ratio [HR] =2.86, 95% confidence interval [CI] = 1.04-8.16, P = .04) and vascular invasion (HR = 4.35, 95% CI = 1.21-15.63, P = .03) as being associated with a significantly worse rate of recurrence-free survival. CONCLUSION: CDX2 was expressed in 1/3 of LCNEC but not associated with prognostic factor. Adjuvant chemotherapy and vascular invasion were associated with a negative prognostic factor of LCNEC.
RESUMO
BACKGROUND: It currently remains unknown whether the resection of cervical polyps during pregnancy leads to miscarriage and/or preterm birth. This study evaluated the risk of spontaneous PTB below 34 or 37 weeks and miscarriage above 12 weeks in patients undergoing cervical polypectomy during pregnancy. METHODS: This was a retrospective monocentric cohort study of patients undergoing cervical polypectomy for clinical indication. Seventy-three pregnant women who underwent polypectomy were selected, and risk factors associated with miscarriage above 12 weeks or premature delivery below 34 or 37 weeks were investigated. A multivariable regression looking for predictors of spontaneous miscarriage > 12 weeks and PTB < 34 or 37 weeks were performed. RESULTS: Sixteen patients (21.9%, 16/73) had spontaneous delivery at < 34 weeks or miscarriage above 12 weeks. A univariate analysis showed that bleeding before polypectomy [odds ratio (OR) 7.7, 95% confidence interval (CI) 1.6-37.3, p = 0.004], polyp width ≥ 12 mm (OR 4.0, 95% CI 1.2-13.1, p = 0.005), the proportion of decidual polyps (OR 8.1, 95% CI 1.00-65.9, p = 0.024), and polypectomy at ≤10 weeks (OR 5.2, 95% CI 1.3-20.3, p = 0.01) were significantly higher in delivery at < 34 weeks than at ≥34 weeks. A logistic regression analysis identified polyp width ≥ 12 mm (OR 11.8, 95% CI 2.8-77.5, p = 0.001), genital bleeding before polypectomy (OR 6.5, 95% CI 1.2-55.7, p = 0.025), and polypectomy at ≤10 weeks (OR 5.9, 95% CI 1.2-45.0, p = 0.028) as independent risk factors for predicting delivery at < 34 weeks. Polyp width ≥ 12 mm and bleeding before polypectomy are risk factors for PTB < 37 wks. CONCLUSIONS: Our cohort of patients undergoing polypectomy in pregnancy have high risks of miscarriage or spontaneous premature delivery. It is unclear whether these risks are given by the underlying disease, by surgical treatment or both. This study establishes clinically relevant predictors of PTB are polyp size> 12 mm, bleeding and first trimester polypectomy. PTB risks should be exposed to patients and extensively discussed with balancing against the benefits of intervention in pregnancy.

OBJECTS: There is growing evidence that sphingosine 1-phosphate (S1P) is involved in inflammatory diseases. As endometriosis is known as an inflammatory disease, we investigated the role of S1P system in the development of endometriosis. METHODS: The expression of sphingosine kinase (SphK) 1 in endometriosis lesions was examined by immunohistochemistry. The cystic fluid of ovarian cysts/tumors were obtained to measure S1P concentrations. Endometriotic stromal cells (ESC) derived from endometrioma were used for in vitro experiments. RESULTS: Sphingosine kinase 1 was detected in epithelium and stromal cells of endometriotic lesions. The mean S1P concentration in the cystic fluid of endometriomas was higher than that in nonendometriomas significantly (98.2 nM vs less than 1.5 nM, P < .01). Interleukin-1ß (IL-1ß) or transforming growth factor-ß exhibited 2.7-fold and 11.5-fold increase in SphK1 messenger RNA (mRNA) expression in ESC, respectively (P < .01). Higher dose of S1P (125nM) increased the cell number of ESC by 20%, and low dose of S1P (1.25 nM and 12.5 nM) induced IL-6 mRNA production and IL-6 secretion by ESC dose-dependently. JTE013, an antagonist for S1PR2, partially suppressed IL-6 induction by S1P (P < .05). JTE013 and VPC23019, an antagonist for S1PR1 and S1PR3, suppressed the ESC proliferation induced by S1P. CONCLUSION: The present study for the first time proved that the SphK-S1P-S1PR axis play a role of accelerating inflammation and growth of endometriotic cells.

OBJECTIVES: It is very hard to estimate an abnormal or normal fetal karyotype in miscarriage before surgery. We investigated whether the abnormal fetal karyotype in early miscarriage could be estimated by comprehensive ultrasonographic findings by a multivariate analysis. METHODS: One hundred fifty-one patients with early miscarriage (<12 weeks' gestation) were selected in our hospital. The clinical characteristics were compared between pregnant women carrying a fetus with an abnormal karyotype and those with a normal one, and the size and configuration of the gestational sac, yolk sac, and embryo at diagnosis of early miscarriage were also evaluated. RESULTS: The rate of abnormal fetal karyotypes was 66.2 % (100 of 151). A maternal age older than 35 years (odds ratio, 3.2; 95% confidence interval, 1.4-7.4; P = .005), yolk sac larger than 5 mm (odds ratio, 6.2; 95% confidence interval, 2.2-22.7, P < .001), and absent embryo (odds ratio, 0.40; 95% confidence interval, 0.16-0.95; P = .038) were independent markers for predicting an abnormal fetal karyotype by multiple logistic regression analysis. CONCLUSIONS: At the point of early miscarriage diagnosis, a yolk sac larger than 5 mm suggests an abnormal fetal karyotype, whereas an absent embryo indicates a normal fetal karyotype.

Enterolithiasis is an uncommon finding of a dilated hyperechogenic bowel with multiple ball-like echogenic structures at a routine prenatal check-up using ultrasonography. We here report a case of prenatally diagnosed enterolithiasis at 18 weeks of gestation, showing multiple hyperechogenic foci rolling within the bowel fluid after peristalsis. The size of the dilated bowel gradually increased during pregnancy. Magnetic resonance image demonstrated the dilated lower bowel with blind-ending rectum. A postnatal contrast medium study with retrograde urethrography revealed a middle imperforate anus and a rectourethral fistula. A careful examination, even before 20 weeks of gestation, is extremely useful in demonstrating intraluminal coarse calcifications within an echogenic bowel.

PURPOSE: This prospective study aimed to examine postoperative dimensional changes in the buccal bone and mucosa around single-stage implants placed in the posterior region. MATERIALS AND METHODS: The dimensions of peri-implant tissue around screw-type implants placed in the posterior region were examined at surgery (baseline) and 6 months and 1 year after surgery. The lateral contour of the buccal bone and mucosa was horizontally measured at five vertical heights at 1-mm intervals (+1 to -3 mm from the implant platform) using custom-designed instruments. Bone resorption on the proximal sides was assessed on radiographs. Mucosal recession was measured on plaster casts of the dentition. RESULTS: Sixty-six implants placed in 30 patients were examined. All implants were clinically osseointegrated and stable throughout the study period. The buccal bone exhibited horizontal resorption throughout the study period, even at the most apical height measured. Assessed at each height, thicker bone (> 2 mm thick) tended to exhibit horizontal resorption during the first 6 months after surgery. However, the bone resorbed horizontally by approximately 0.4 mm during the final 6 months, irrespective of its contour. Vertical resorption of the buccal marginal bone was approximately 1 mm during the period from 6 months to 1 year. The bone-retaining group at the 1-year time point was found to have thicker bone walls at baseline compared with the bone-loss group. The thickness of the buccal mucosa showed little change. There was no obvious correlation between buccal bone resorption and mucosal recession. CONCLUSIONS: The buccal bone exhibited both horizontal and vertical resorption over the year after surgery. The initial contour of the bone was significantly associated with bone retention or loss at 1 year. However, mucosal recession was not directly affected by buccal bone resorption.

BACKGROUND: Because carcinomatous lymphangitis and carcinomatous pleuritis are the usual forms of metastasis associated with gastric cancer, resection of solitary pulmonary metastases arising from gastric cancer is rarely performed. To clarify the characteristics of pulmonary metastases from gastric cancer, we investigated patients who underwent resection of metastatic solitary lung tumors arising from gastric cancer. METHODS: Between October 2003 and October 2012, 10 patients underwent pulmonary metastasectomy for metastatic gastric cancer at our institution. We retrospectively evaluated features of the primary gastric cancer and the clinicopathological features of the pulmonary metastases in these cases. RESULTS: 70% of the patients had stage II disease. Lymphatic invasion was observed in all cases of primary gastric cancer. The method of pulmonary resection was partial resection in 5 cases, segmentectomy in 1, and lobectomy in 4. On histopathological examination, immunohistochemical staining was negative for thyroid transcription factor-1 and napsin A in all cases. Patients who underwent resection of pulmonary metastases arising from gastric cancer had a good prognosis: the 4-year survival rate was 75%. CONCLUSIONS: Carefully chosen patients have a good opportunity to obtain benefits from resection of pulmonary metastases arising from gastric cancer.

BACKGROUND: Recently, the role of the amino acid arginine in wound healing has been emphasized. We studied whether postoperative enteral arginine supplementation can contribute to the resolution of prolonged air leakage after lung resections. METHODS: 42 patients undergoing lung resection at our institutions from 2009 to 2012 were enrolled in this study. In these patients, continuous air leakage in the expiratory phase was identified on the day of surgery and on the following day. The patients were divided into 2 groups; the first group included 21 patients consuming 3 packs of an arginine supplement beverage daily postoperatively, and the second group (control) included 21 patients who did not consume any additional supplements. The durations of air leakage and chest tube drainage were compared between the two groups. RESULTS: The mean durations of air leakage and chest tube drainage were shorter in the arginine supplementation group (4.4 vs. 6.7 days, p = 0.010; 6.5 vs. 8.3 days, p = 0.042, respectively). CONCLUSION: Postoperative enteral arginine supplementation may contribute to stopping air leaks after lung surgery.

PURPOSE: There are very few reports regarding the outcome of lung cancer surgery in patients with schizophrenia, and the clinical features of such patients are still unclear. METHODS: From 2004 to 2012, 11 lung cancer patients (six male, five female; mean age, 62.7 years) with schizophrenia underwent lung resections at our institutions. All patients had been institutionalized because they were unable to live independently at home. We retrospectively evaluated their postoperative clinical outcomes and long-term results. RESULTS: Ten of the 11 patients had comorbidities, such as diabetes mellitus and chronic obstructive pulmonary disease. Preoperatively, two patients had a history of treatment for other primary cancers in other organs, and one was on hemodialysis. A lobectomy was performed in nine patients, a segmentectomy in one, and a partial resection in one. There were no hospital deaths. The postoperative morbidity included two cases of pneumonia, one of atelectasis, and one of prolonged air leakage lasting more than 7 days. Wandering was postoperatively observed in two patients; one of these fell and fractured the left femur. At the time of our investigation, two patients were deceased, and the overall 5-year survival rate was 74.1 %. CONCLUSIONS: The postoperative morbidity and long-term results of schizophrenic patients with lung cancer were acceptable. Therefore, even in patients with schizophrenia, surgical treatment for lung cancer should be recommended when deemed to be necessary.

PURPOSE: To evaluate (18)F-fluorodeoxyglucose (FDG) uptake to predict the malignant nature and analyze the correlation between FDG uptake and expression of glucose transporter 1 (Glut-1) and hexokinase II (HK-II) in thymic epithelial tumors. MATERIALS AND METHODS: Eleven patients with a thymic epithelial tumor who underwent FDG PET/CT before therapy were reviewed. The thymic tumors were classified by the WHO histological classification and Masaoka clinical staging. Comparison of maximum standardized uptake value (SUV(max)) of the lesion was made between the low-risk (Type A, AB and B1) and high-risk {Type B2, B3 and C (thymic cancer)} groups and among clinical stages. Expression of Glut-1 and HK-II was analyzed immunohistochemically. RESULTS: All 11 tumors showed FDG uptake visually. SUV(max) was significantly higher in the high-risk group (n=5, 5.24 ± 2.44) than the low-risk group (n=6, 3.05 ± 0.55) (P=0.008). Staining scores of both Glut-1 and HK-II were significantly higher in the high-risk group than in the low-risk group (Glut1: P=0.034 and HK-II: P=0.036). There were no significant differences in SUV(max) (P=0.11), Glut-1 (P=0.35) and HK-II scores (P=0.29) among clinical stages. SUV(max) was significantly correlated to each of the staining scores of Glut-1 (ρ=0.68, P=0.031) and HK-II (ρ=0.72, P=0.024). CONCLUSION: These preliminary results support the previously published view that SUV(max) may be useful to predict the malignant nature of thymic epitherial tumors and suggest that the degree of FDG uptake in the thymic epitherial tumors is closely related to the amount of Glut-1 and HK-II in the tumor.

A pregnant woman was diagnosed with acute promyelocytic leukemia at 38 weeks of gestation. Induction of labor was successful, and the patient delivered a healthy male baby. Soon after delivery, she was treated with chemotherapy using all-trans-retinoic acid (ATRA). The number of white blood cells was increased on the fifth postpartum day and retinoic acid syndrome (RAS) was considered a concern. On the sixth postpartum day, remission induction chemotherapy with idarubicin and cytosine arabinoside was started. On the seventh postpartum day, massive uterine bleeding of more than 1300 mL suddenly occurred. As administration of cytotoxic agents may induce disseminated intravascular coagulation, we should take care to avoid uterine bleeding after chemotherapy in acute promyelocytic leukemia cases treated soon after delivery.

OBJECTIVE: The purpose of this study was to determine the proportion of circulating T and natural killer (NK) cells that express intracellular vascular endothelial growth factor (VEGF) in women with preeclampsia compared to those with a normal pregnancy. STUDY DESIGN: In all, 24 preeclamptic patients and 30 healthy pregnant women were involved in this case-control study. Intracellular VEGF expression of unstimulated lymphocytes was determined with flow cytometric examination. RESULTS: In healthy pregnant women, the majority of both T and NK cells expressed VEGF in their cytoplasma (median, 79.9%; 25-75 percentile, 73.7-87.0 and median, 78.3%; 25-75 percentile, 64.1-85.3, respectively). Furthermore, CD4(+) helper and CD8(+) cytotoxic T cells showed a similar pattern of VEGF expression in normal pregnancy. However, the proportion of VEGF-expressing peripheral blood T (both helper and cytotoxic) and NK cells was markedly decreased in preeclampsia (for T cells: median, 51.6%; 25-75 percentile, 40.1-60.0; P < .001; for NK cells: median, 45.2%; 25-75 percentile, 27.4-64.0; P < .001). CONCLUSION: Our results suggest decreased production of VEGF by circulating T and NK cells in preeclampsia, which might contribute to the development of the generalized endothelial dysfunction characteristic of the maternal syndrome of the disease.

Chorioamnionitis (CAM) is a major cause of preterm delivery. Inflammatory cytokines and chemokines play important roles in the pathogenesis of preterm delivery. Interleukin (IL)-17 is a key cytokine which induces inflammation and is critical to host defense. In this study, we examined the role of IL-17 in the pathogenesis of preterm delivery. The levels of cytokines including IL-17, IL-8 and tumor necrosis factor (TNF) alpha were measured by ELISA in amniotic fluid from 154 cases of preterm labor. Flow cytometry and immunohistochemical staining were performed to determine the distribution of IL-17-producing cells. IL-8 secretion was evaluated in primary cultured human amniotic mesenchymal (HAM) cells and human amniotic epithelial (HAE) cells stimulated with IL-17, TNFalpha or IL-1beta. We also studied the signaling pathway of IL-17 and TNFalpha in HAM cells. Levels of inflammatory cytokines in amniotic fluid were higher in preterm delivery cases than in term delivery cases. Furthermore, IL-8, IL-17 and TNFalpha levels were significantly higher in the preterm cases with CAM stage II or III than those without CAM. Flow cytometry and immunohistochemical staining revealed that CD3(+)CD4(+) T cells were the main source of IL-17 in the chorioamniotic membrane. Interestingly, TNFalpha-induced IL-8 secretion was enhanced by IL-17 in a dose-dependent manner in HAM cells. The IKK inhibitor BMS-345541 and mitogen-activated protein kinase (MAPK) inhibitors p38, JNK and p42/44 (ERK1/2 pathway) reduced IL-8 secretion by IL-17-stimulated and TNFalpha-stimulated HAM cells. These results indicate that IL-17, produced by T cells, promotes inflammation at the fetomaternal interface in preterm delivery.

We experienced a very rare case of late pulmonary metastasis from ACC. The patient was a 40-year-old woman who had undergone a left adrenectomy 12 years earlier. Instead of a large metastatic lung tumor with hemothorax and the existence of metastases in other organs, combined therapy of repeated resections for metastases and adjuvant therapy allowed for almost a 36-month survival following the first recurrence and a good quality of life. In addition, a blood and pathological study revealed that the tumor in this case was an alpha-fetoprotein-producing ACC, which is, as far as we could ascertain, the first case of its kind.

BACKGROUND: Few reports have described surgery for lung cancer in patients with liver cirrhosis. The objective of this study was to clarify the efficacy of surgical treatment and evaluate its postoperative outcome. METHODS: We retrospectively reviewed the medical charts of 17 patients between 1985 and 2005 who were found to have nonsmall cell lung cancer (NSCLC) with liver cirrhosis. The grading of the severity of liver cirrhosis was made according to the Child-Pugh classification. RESULTS: Four patients were classified as Child-Pugh class A, whereas another 13 patients were classified as Child-Pugh class B. Of these 17 patients, 11 underwent lobectomies, 3 underwent pneumonectomies, and 3 underwent wedge resections. The only patient who experienced hospital death (5.9%) was a male patient with Child-Pugh class B cirrhosis. There were five respiratory-associated postoperative complications including pneumonia, bleeding from the staple line, and prolonged air leak. The morbidity rate was 29.5%. Median duration of chest tube insertion was 6.8 days, and mean volume of pleural effusion was 1,015.0 mL at 3 days total postoperatively. A total of 9 deaths occurred during follow-up (3 from cancer, 4 from hepatic failure, 1 from cardiac causes, and 1 unknown). The overall survival was 87.8%, 57.0%, and 45.6% at 1, 3, and 5 years, respectively. None of the patients experienced morbidity or mortality in Child-Pugh class A, but class B had 30.8% morbidity and 7.6% mortality. CONCLUSIONS: Surgical treatment may be an acceptable and valuable approach for NSCLC patients who also have low severity liver cirrhosis.
