National registry of thoracoamniotic shunting using a double-basket catheter: A post-marketing surveillance registry of 295 patients with fetal hydrothorax.

OBJECTIVE: We report on the 1-year outcomes of fetuses who underwent thoracoamniotic shunting (TAS) with a double-basket catheter for fetal hydrothorax (FHT) using a national post-marketing surveillance registry. METHODS: This surveillance study was conducted for cases enrolled between 2011 and 2019. Preoperative, operative, and postoperative findings and outcomes had to be reported through the national surveillance website. RESULTS: Forty-three institutes enrolled 295 patients. In 60 patients, associated abnormalities were diagnosed after birth. Among the 235 patients with isolated hydrothorax, the survival rate at 1 year of age was 70.5%. Among these patients, 89% did not require oxygen or other respiratory support. The 1-year survival rate in complicated cases was 27%. Trisomy 21 was the most common associated problem (40%). Catheter associated problems, including dislocation (25%), obstruction (24%), and preterm rupture of the membranes (6%) were observed, but there were no severe maternal complications. TAS before 29.5 weeks of gestation (odds ratio [OR] 0.16) and skin edema and ascites (OR 0.06) were risk factors for death at one year, whereas appropriate shunt location for >28 days (OR 4.2) was a protective factor. CONCLUSION: We report a favorable survival rate in fetuses with isolated FHT treated with this double-basket catheter.

Dysphagia risk evaluated by the Eating Assessment Tool-10 is associated with health-related quality of life in patients with chronic liver disease.

OBJECTIVE: This study aimed to reveal the prevalence and characteristics of individuals at risk of dysphagia in patients with chronic liver disease (CLD) and its association with health-related quality of life (HRQOL). METHODS: This cross-sectional study included 335 outpatients with CLD. Dysphagia risk, sarcopenia risk, malnutrition risk, and HRQOL were assessed using the Eating Assessment tool-10 (EAT-10), SARC-F, Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT), and Chronic Liver Disease Questionnaire (CLDQ), respectively. Dysphagia risk and low HRQOL were based on EAT-10 ≥3 and CLDQ overall score <5, respectively. Factors associated with dysphagia risk and low HRQOL were assessed using the logistic regression model. RESULTS: Dysphagia risk and lower HRQOL were observed in 10% and 31% of the patients, respectively. Patients with dysphagia risk were older, had lower liver functional reserve, were at higher risk for sarcopenia and malnutrition, and showed lower CLDQ overall score (median, 4.41 vs. 5.69; P < 0.001) than those without. After adjustment, SARC-F (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.02-1.50; P = 0.029) and RFH-NPT (OR, 1.71; 95% CI, 1.04-2.81; P = 0.034) scores were independently associated with dysphagia risk. EAT-10 (OR, 1.17; 95% CI, 1.04-1.30; P = 0.008) and SARC-F (OR, 1.37; 95% CI, 1.18-1.59; P < 0.001) scores were also independently associated with low HRQOL. CONCLUSIONS: Dysphagia risk was prevalent in approximately 10% of patients with CLD and was associated with a risk of sarcopenia and malnutrition. Furthermore, dysphagia risk was related to HRQOL in patients with CLD.

Nutritional counseling improves mortality and prevents hepatic encephalopathy in patients with alcohol-associated liver disease.

AIM: Nutritional counseling improves malnutrition, which determines the prognosis of patients with chronic liver disease. In this study, we investigated the effects of nutritional counseling on mortality and the risk of overt hepatic encephalopathy (HE) in patients with alcohol-associated liver disease. METHODS: In this retrospective cohort study, we included 211 patients with alcohol-associated liver disease who visited Gifu University Hospital between August 2008 and June 2023. Patients were classified into two groups according to the frequency of nutritional counseling by a registered dietitian. The primary outcomes were all-cause mortality and overt HE. Propensity score matching analysis was performed to adjust for potential confounders. RESULTS: Among the patients (median age 67 years; 88% men; and median Model for End-Stage Liver Disease score, 9), 86 (39%) were in the high-frequency (≥2) nutritional counseling group. The high-frequency group had a significantly higher survival rate (46% vs. 25%) and a lower incidence of overt HE (16% vs. 27%) at 5 years than the low-frequency group. Nutritional counseling was associated with a reduced risk of mortality (hazard ratio [HR] 0.48; 95% confidence interval [CI] 0.36-0.63) and overt HE (HR 0.64; 95% CI 0.42-0.99), independent of hepatocellular carcinoma and liver function reserve. After propensity score matching, nutritional counseling was still associated with a reduced risk of mortality (HR 0.34; 95% CI 0.19-0.59) and overt HE (HR 0.31; 95% CI 0.11-0.87). CONCLUSIONS: Nutritional counseling effectively improves mortality and prevents overt HE in patients with alcohol-associated liver disease, thereby proving essential for the management of these patients.

A Case of Unresectable Combined Hepatocellular-cholangiocarcinoma Treated with Combination Therapy Consisting of Durvalumab Plus Tremelimumab.

Combined hepatocellular cholangiocarcinoma is a rare and challenging primary liver malignancy that lacks any established standard treatments for unresectable cases. We herein present the first known case of a 49-year-old woman diagnosed with unresectable combined hepatocellular-cholangiocarcinoma, who underwent novel chemotherapy involving durvalumab plus tremelimumab combination therapy. The treatment was temporarily discontinued owing to immune-related adverse events, such as rash, and the patient was subsequently managed with systemic steroid therapy; however, the disease progressed after two courses of this treatment. Further studies are needed to validate the efficacy and safety of immune checkpoint inhibitors such as durvalumab and tremelimumab for the treatment of unresectable combined hepatocellular cholangiocarcinoma.

Postpartum and interpregnancy care of women with a history of hypertensive disorders of pregnancy.

Hypertensive disorders of pregnancy (HDP) are common complications associated with maternal and neonatal morbidity and mortality worldwide. Insights gained from long-term cohort studies have revealed that women with a history of HDP are predisposed to recurrent HDP in subsequent pregnancies and face heightened risks for cardiovascular and metabolic diseases later in life. Pregnancy is a unique condition that overloads maternal cardiac and metabolic functions, and is recognized as a "maternal stress test" for future cardiovascular and metabolic diseases. Pregnancy and postpartum period provide a valuable opportunity for identifying women with underlying and unrecognized cardiovascular and metabolic risk factors. Establishing an effective postpartum healthcare program for women who have experienced HDP is crucial in reducing the future risk of health complications. Postpartum care consists of supportive care for both mothers and children, including not only the assessment of physical and psychological well-being but also long-term postpartum preventive health management. Interpregnancy care is a continuum from postpartum care and includes supportive care to prepare for future pregnancies. Various initiatives across nations have been initiated to establish follow-up programs for women with a history of HDP; however, sufficient evidence of the impact of such programs is not available. Substantial challenges persist in establishing an efficient postpartum follow-up program, including educational strategies, selection of effective lifestyle interventions, and collaboration among various healthcare providers. This review outlines the postpartum and interpregnancy care of women who have experienced HDP as well as the current status and challenges of related healthcare initiatives in Japan.

Animal naming test stratifies the risk of falls and fall-related fractures in patients with cirrhosis.

This study aimed to determine the relationship between animal naming test (ANT), falls, and fall-related fractures in patients with cirrhosis. Cognitive impairment and frailty were assessed using ANT and Karnofsky performance status (KPS), respectively. Factors stratifying the risk of previous falls and fall-related fractures within 1 year were assessed using a logistic regression model. Factors affecting patient performance in ANT were evaluated using multiple regression analysis. Of the 94 patients, 19% and 5% experienced falls and fall-related fractures, respectively. The performance in ANT was worse in patients who experienced falls (11 vs. 18; p < 0.001) and fall-related fractures (8 vs. 16; p < 0.001) than in those who did not. After adjustment, females, KPS, and ANT (odds ratio [OR], 0.78; 95% confidence interval [CI], 0.65-0.93; p = 0.005) were associated with falls, while ANT was significantly associated with fall-related fractures (OR, 0.56; 95% CI 0.35-0.88; p = 0.012). Age and education affected the performance in ANT, whereas the use of Oriental zodiac did not. The ANT is useful for stratifying the risk of falls and fall-related fractures in patients with cirrhosis. The effects of age and education should be considered when applying ANT in the Japanese population.

Serum MYCN as a predictive biomarker of prognosis and therapeutic response in the prevention of hepatocellular carcinoma recurrence.

The proto-oncogene MYCN expression marked a cancer stem-like cell population in hepatocellular carcinoma (HCC) and served as a therapeutic target of acyclic retinoid (ACR), an orally administered vitamin A derivative that has demonstrated promising efficacy and safety in reducing HCC recurrence. This study investigated the role of MYCN as a predictive biomarker for therapeutic response to ACR and prognosis of HCC. MYCN gene expression in HCC was analyzed in the Cancer Genome Atlas and a Taiwanese cohort (N = 118). Serum MYCN protein levels were assessed in healthy controls (N = 15), patients with HCC (N = 116), pre- and post-surgical patients with HCC (N = 20), and a subset of patients from a phase 3 clinical trial of ACR (N = 68, NCT01640808). The results showed increased MYCN gene expression in HCC tumors, which positively correlated with HCC recurrence in non-cirrhotic or single-tumor patients. Serum MYCN protein levels were higher in patients with HCC, decreased after surgical resection of HCC, and were associated with liver functional reserve and fibrosis markers, as well as long-term HCC prognosis (>4 years). Subgroup analysis of a phase 3 clinical trial of ACR identified serum MYCN as the risk factor most strongly associated with HCC recurrence. Patients with HCC with higher serum MYCN levels after a 4-week treatment of ACR exhibited a significantly higher risk of recurrence (hazard ratio 3.27; p = .022). In conclusion, serum MYCN holds promise for biomarker-based precision medicine for the prevention of HCC, long-term prognosis of early-stage HCC, and identification of high-response subgroups for ACR-based treatment.

Predicting preterm birth within 2 weeks in asymptomatic women with a short cervix: Combined effects of cervicovaginal fluid cytokine levels and fetal fibronectin test.

AIMS: To predict preterm birth (PTB) accurately, we conducted a comprehensive cytokine assay using cervicovaginal fluid (CVF) and evaluated the additive effects of cytokine levels on the fetal fibronectin (fFN) test. METHODS: A total of 645 CVF samples were collected from 256 asymptomatic pregnant women between 24 and 35 weeks gestation, exhibiting short cervix. After selection based on specific criteria, 17 cytokines in 105 CVF samples were simultaneously measured using multiplex assay. Multivariate logistic regression analysis was performed to evaluate the association between cytokine levels and impending PTB, which is defined as PTB within 2 weeks after CVF collection. Moreover, receiver operating characteristic (ROC) analysis was performed in women with positive fFN results, which was validated using another set of 65 CVF samples. RESULTS: In positive fFN women, the CCL2 level was significantly higher in the impending PTB group than the other group (p < 0.01) and a predictor of impending PTB (adjusted odds ratio 1.020, 95% confidence interval [95% CI] 1.003-1.038, p = 0.020). The cutoff value of CCL2 was 64.8 pg/mL (are under the curve 0.726, p = 0.004, 95% CI 0.593-0.859, sensitivity 45.2%, specificity 91.7%). Additionally, the reliable classification performance of proposed ROC model could be validated. However, measuring cytokine levels could not help in predicting impending PTB in women with negative fFN or normal labor onset in healthy-term women. CONCLUSION: Comprehensive analysis of CVF cytokines revealed that the CCL2 level significantly improves the prediction of impending PTB in asymptomatic fFN-positive women with a short cervix, which may contribute to better clinical management.

Lenvatinib Exacerbates the Decrease in Skeletal Muscle Mass in Patients with Hepatocellular Carcinoma, Whereas Atezolizumab Plus Bevacizumab Does Not.

This study aimed to evaluate chronological changes in skeletal muscle index (SMI), subcutaneous and visceral adipose tissue indices (SATI and VATI), AFP, PIVKA-II, and ALBI scores during atezolizumab plus bevacizumab (AB) or lenvatinib (LEN) treatment for hepatocellular carcinoma (HCC) and the effect of these changes on survival. A total of 94 patients with HCC (37 were on AB and 57 on LEN) were enrolled. SMI, SATI, VATI, AFP, PIVKA-II, and ALBI scores were analyzed at the time of the treatment introduction (Intro), 3 months after the introduction (3M), at drug discontinuation (End), and the last observational time (Last). The differences between chronological changes were analyzed using the Wilcoxon paired test. The independent predictors for survival and the changes in SMI during AB or LEN (c-SMI%) were analyzed using the Cox proportional hazards model treating all these factors as time-varying covariates and the analysis of covariance, respectively. SMI in the AB group was maintained over time (42.9-44.0-40.6-44.2 cm2/m2), whereas that in the LEN group significantly decreased during the Intro-3M (p < 0.05) and 3M-End (p < 0.05) period (46.5-45.1-42.8-42.1 cm2/m2). SMI (p < 0.001) was an independent predictor for survival together with AFP (p = 0.004) and ALBI score (p < 0.001). Drug choice (AB or LEN; p = 0.038) and PIVKA-II (p < 0.001) were extracted as independent predictors for c-SMI%. AB treatment was significantly superior to LEN in terms of maintaining skeletal muscle, which is an independent predictor for survival.

Intrauterine exposure to chorioamnionitis and neuroanatomical alterations at term-equivalent age in preterm infants.

PURPOSE: Infants born to mothers with chorioamnionitis (CAM) are at increased risk of developing adverse neurodevelopmental disorders in later life. However, clinical magnetic resonance imaging (MRI) studies examining brain injuries and neuroanatomical alterations attributed to CAM have yielded inconsistent results. We aimed to determine whether exposure to histological CAM in utero leads to brain injuries and alterations in the neuroanatomy of preterm infants using 3.0- Tesla MRI at term-equivalent age. METHODS: A total of 58 preterm infants born before 34 weeks of gestation at Nagoya University Hospital between 2010 and 2018 were eligible for this study (CAM group, n = 21; non-CAM group, n = 37). Brain injuries and abnormalities were assessed using the Kidokoro Global Brain Abnormality Scoring system. Gray matter, white matter, and subcortical gray matter (thalamus, caudate nucleus, putamen, pallidum, hippocampus, amygdala, and nucleus accumbens) volumes were evaluated using segmentation tools (SPM12 and Infant FreeSurfer). RESULTS: The Kidokoro scores for each category and severity in the CAM group were comparable to those observed in the non-CAM group. White matter volume was significantly smaller in the CAM group after adjusting for covariates (postmenstrual age at MRI, infant sex, and gestational age) (p = 0.007), whereas gray matter volume was not significantly different. Multiple linear regression analyses revealed significantly smaller volumes in the bilateral pallidums (right, p = 0.045; left, p = 0.038) and nucleus accumbens (right, p = 0.030; left, p = 0.004) after adjusting for covariates. CONCLUSIONS: Preterm infants born to mothers with histological CAM showed smaller volumes in white matter, pallidum, and nucleus accumbens at term-equivalent age.

Interleukin-17A stimulation induces alterations in Microglial microRNA expression profiles.

BACKGROUND: Increased maternal interleukin (IL)-17A and activated microglia are pivotal factors contributing to the pathological phenotypes of maternal immune activation (MIA), developing neurodevelopmental disorders in offspring. This study aimed to determine whether IL-17A affects the microglial microRNA (miRNA) profiles. METHODS: The miRNA expression profiles of primary cultured microglia stimulated with recombinant IL-17A were examined comprehensively using miRNA sequencing and validated through qRT-PCR. The expressions of miRNAs target genes identified using bioinformatics, were investigated in microglia transfected with mimic miRNA. The target gene's expression was also examined in the fetal brains of the MIA mouse model induced by maternal lipopolysaccharide (LPS) administration. RESULTS: Primary cultured microglia expressed the IL-17A receptor and increased proinflammatory cytokines and nitric oxide synthase 2 upon treatment with IL-17A. Among the three miRNAs with |log2FC | >1, only mmu-miR-206-3p expression was significantly up-regulated by IL-17A. Transfection with the mmu-miR-206-3p mimic resulted in a significant decrease in the expression of Hdac4 and Igf1, target genes of mmu-miR-206-3p. Hdac4 expression also significantly decreased in the LPS-induced MIA model. CONCLUSIONS: IL-17A affected microglial miRNA profiles with upregulated mmu-miR-206-3p. These findings suggest that targeting the IL-17A/mmu-miR-206-3p pathway may be a new strategy for predicting MIA-related neurodevelopmental deficits and providing preventive interventions. IMPACT: Despite the growing evidence of interleukin (IL)-17A and microglia in the pathology of maternal immune activation (MIA), the downstream of IL-17A in microglia is not fully known. IL-17A altered microRNA profiles and upregulated the mmu-miR-206-3p expression in microglia. The mmu-miR-206-3p reduced autism spectrum disorder (ASD) related gene expressions, Hdac4 and Igf1. The Hdac4 expression was also reduced in the brain of MIA offspring. The hsa-miR-206 sequence is consistent with that of mmu-miR-206-3p. This study may provide clues to pathological mechanisms leading to predictions and interventions for ASD children born to mothers with IL-17A-related disorders.

A survey questionnaire evaluating physical activity patterns and determinants in patients with chronic liver disease.

BACKGROUND: Physical activity can reduce the risk of morbidity and mortality in patients with chronic liver disease (CLD), whereas physical inactivity adversely affects clinical outcomes. Since data on physical activity in CLD are scarce, we conducted a questionnaire survey to assess the physical activity patterns and determinants in patients with CLD. METHODS: We surveyed 437 patients from outpatient clinics at Gifu University Hospital about their physical activity patterns and determinants in 2022 using a validated questionnaire. The primary objective was to examine the proportion of patients who exercised and the clinical characteristics of patients who achieved high levels of physical activity. The secondary objectives were to explore the types, motivations, barriers, and preferences for physical activity. RESULTS: Among the 397 eligible patients (median age 68 years; 51% men; and median Model for End-Stage Liver Disease score 6), 55.4% reported performing physical activity less than once a week. Physical activity frequency was not associated with sex, body mass index, comorbidities, or hepatic reserve. Among the respondents, 60.4% expressed concern regarding physical strength, and 80.6% expressed concern regarding physical inactivity. The main barriers to physical activity were work, household chores, and health problems. However, many respondents expressed their willingness to increase their physical activity frequency with some promotional policies. Walking was the most common physical activity practiced in the past year and the activity most respondents wanted to try in the future. CONCLUSIONS: Patients with CLD are insufficiently active and need physical activity interventions, especially regarding walking.

A case of A20 haploinsufficiency complicated by autoimmune hepatitis.

AIM: A20 haploinsufficiency (HA20) is a recently described autoinflammatory disease that manifests symptoms similar to those of Behçet's disease. However, little is known about the involvement of the liver in HA20. Here, we report a case of HA20 complicated by autoimmune hepatitis (AIH). CASE PRESENTATION: A 33-year-old woman was previously diagnosed with HA20 and chronic thyroiditis, and was treated with prednisolone (PSL; 7.5 mg/day) and levothyroxine sodium hydrate (125 µg/day). She experienced general malaise and jaundice, and biochemical evaluation revealed elevated liver function with an aspartate aminotransferase level of 817 U/L, an alanine aminotransferase level of 833 U/L, and a total bilirubin of 8.3 mg/dL. Pathological evaluation of the liver biopsy revealed interface hepatitis and the patient was diagnosed with acute exacerbation of AIH. Upon increasing the PSL dose to 60 mg/day, the liver enzyme levels rapidly decreased. During tapering of PSL, azathioprine 50 mg/day was added, and there was no relapse of AIH with combination therapy of PSL 7 mg/day and azathioprine 50 mg/day. CONCLUSION: This is the first report of biopsy-proven AIH in an Asian patient with HA20. This case has significant implications for the pathogenesis and treatment of AIH in patients with HA20.

Sex-specific differences in head circumference of term singletons after assisted reproductive technology: a multicentre study in Japan.

RESEARCH QUESTION: Does fertility treatment, specifically assisted reproductive technology (ART), affect head circumference in term singletons? DESIGN: A total of 32,651 women who delivered at term at 12 maternity hospitals in Japan between 2010 and 2018 were included in the analysis; of these, 1941 (5.9%) and 2984 (9.1%) women conceived through ART and non-ART fertility treatments (timed intercourse, ovulation induction or artificial insemination), respectively. The study evaluated the adjusted odds ratios of head circumference ≥90th percentile stratified by infant sex and type of ART procedure after adjusting for covariates, with natural conception as the reference group. RESULTS: ART significantly increased the risk of head circumference ≥90th percentile (adjusted odds ratio 1.56 [95% confidence interval 1.25-1.96]), whereas non-ART fertility treatment did not increase the risk (1.14 [0.92-1.42]). This increased risk of head circumference ≥90th percentile was observed exclusively in male neonates (1.73 [1.33-2.26]) and not in female neonates (1.18 [0.76-1.85]) in the ART group. Frozen embryo transfer (FET), FET in a hormone replacement cycle (HRC-FET) and blastocyst-stage embryo transfer were significantly associated with head circumference ≥90th percentile (1.60 [1.26-2.02], 1.70 [1.30-2.22] and 1.72 [1.33-2.24], respectively). CONCLUSIONS: The use of ART, particularly FET, HRC-FET or blastocyst-stage embryo transfer, was linked with a heightened risk of head circumference ≥90th percentile compared with non-ART fertility treatment or natural conception. The increased risk was observed only in male neonates.

Lenvatinib or Sorafenib Treatment Causing a Decrease in Skeletal Muscle Mass, an Independent Prognostic Factor in Hepatocellular Carcinoma: A Survival Analysis Using Time-Varying Covariates.

This study aimed to assess the effects of lenvatinib (LEN) or sorafenib (SOR) treatment for hepatocellular carcinoma (HCC) on body composition and changes in body composition on survival. This study enrolled 77 HCC patients. Skeletal muscle index (SMI), subcutaneous and visceral adipose tissue indices (SATI and VATI), AFP, PIVKA-II, and ALBI scores were analyzed at the time of LEN/SOR introduction, three months after the introduction, at treatment discontinuation, and the last observational time. The differences between chronological changes in these values were analyzed using a paired t-test. The Cox proportional hazards model was used to analyze prognostic factors using time-varying covariates. The chronological changes in each factor were 45.5-43.6-40.6-39.8 (cm2/m2) for SMI, 41.7-41.6-36.3-33.7 (cm2/m2) for SATI, 41.9-41.1-37.1-34.8 (cm2/m2) for VATI, 2.379-26.42-33.61-36.32 (×103 ng/mL) for AFP, 9.404-13.39-61.34-25.70 (×103 mAU/mL) for PIVKA-II, and -2.56--2.38--1.99--1.90 for the ALBI score. The presence of pre-treatment (p = 0.042), AFP (p = 0.002), PIVKA-II (p < 0.001), ALBI score (p < 0.001), and SMI (p = 0.001) were independent prognostic factors. Skeletal muscle mass decreases significantly during LEN/SOR treatment and is an independent prognostic factor for HCC.

FIB­4 index and NAFLD fibrosis score are useful indicators for screening high­risk groups of non­viral hepatocellular carcinoma.

Non-viral hepatocellular carcinoma (HCC) tends to appear in non-cirrhotic livers, rendering it difficult to screen for a high-risk group. The present study aimed to identify the most suitable indicator for screening high-risk groups of non-viral HCC. A total of 190 patients with non-viral HCC, including 126 with non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH), were enrolled in the present study. A total of two cut-off values, for low and high levels of fibrosis, were set for each of the indicators, including the Child-Pugh score (CPS; 6 and 7), platelet counts (15.8 and 10x104/µl), albumin-bilirubin (ALBI) score (-2.60 and -2.27), fibrosis 4 index (FIB-4 index; 1.30 and 2.67) and NAFLD fibrosis score (NFS; -1.455 and 0.675). The ratio of the number of patients who fell outside the cut-off value for all patients was defined as the overlooking rate. The overlooking rates of CPS, platelet counts, ALBI score, FIB-4 index and NFS for the low fibrosis cut-off value were 41.0, 48.9, 35.8, 4.2 and 5.8%, respectively. When performing analysis limited to the NAFLD cases, those of the FIB-4 index and NFS were 4.8 and 6.3%, respectively. Those for the high fibrosis cut-off value were 79.5, 73.2, 62.6, 30.0 and 37.4%, respectively. On the whole, the present study demonstrates that the cut-off values of ≥1.30 for the FIB-4 index or ≥-1.455 for the NFS may be used to screen high-risk groups of HCC among patients with non-viral hepatitis.

Intestinal­type mucinous carcinoma of the endometrium showing a polypoidal exophytic form: A case report.

Although endometrial cancer is a common malignancy in women, rare histological subtypes can pose diagnostic challenges. Primary endometrial intestinal-type mucinous carcinoma is a newly recognized subtype of endometrial cancer that differs from Müllerian-type endometrial mucinous carcinoma. The present case report documents a rare case of intestinal-type mucinous carcinoma of the endometrium showing a polypoidal exophytic form. The patient, an 80-year-old female, was incidentally diagnosed with a uterine tumor during a follow-up for vulvar Paget's disease. Clinical and imaging examinations revealed a localized mass within the uterine cavity. Hysteroscopy and subsequent histological examination confirmed the presence of intestinal-type mucinous carcinoma of the endometrium. Microscopically, the tumor displayed adenocarcinoma containing an intestinal-type glandular epithelium with mild nuclear atypia. It stained positive for the gastrointestinal markers mucin 2 and caudal type homeobox 2, and stained negatively for estrogen receptor α. The patient underwent surgery and adjuvant chemotherapy, with no evidence of recurrence at the latest follow-up 6 months after surgery. Endometrial intestinal-type mucinous carcinoma is a rare histological subtype of endometrial cancer. Differential diagnoses include Müllerian-type endometrial mucinous carcinoma, endocervical adenocarcinoma, metastasis from gastrointestinal tract adenocarcinoma and non-neoplastic gastric/intestinal metaplasia. However, the prognosis of endometrial intestinal-type mucinous carcinoma remains unclear due to limited reported cases. Existing evidence suggests a poorer prognosis compared with classical mucinous carcinomas of the endometrium. The present case, which is characterized by a polypoidal exophytic tumor without myometrial invasion, showed a favorable outcome. Further documentation and characterization of the aforementioned rare malignancy are necessary to enhance the understanding of its clinical physiology and outcomes. The present case report highlights the diagnostic challenges associated with intestinal-type mucinous endometrial carcinoma. The inclusion of this type of malignancy in the latest World Health Organization classification emphasizes the need for further comprehensive studies and case reports to expand the current knowledge on this rare histological subtype.

CLPTM1L expression predicts recurrence of patients with intermediate­ and high­risk stage IB­IIB cervical cancer undergoing radical hysterectomy followed by TP as adjuvant chemotherapy.

According to the National Comprehensive Cancer Network clinical practice guidelines of cervical cancer, concurrent chemoradiotherapy or radiotherapy is suggested for patients who receive radical hysterectomy and have intermediate- and high-risk cervical cancer. However, adjuvant chemotherapy has been increasingly chosen given the adverse events associated with chemoradiotherapy or radiotherapy and the increase in evidence regarding the efficacy of adjuvant chemotherapy. Given that adjuvant chemotherapy is not a standard treatment at present, if recurrence after adjuvant chemotherapy could be predicted, it would assist the decision of gynecological oncologists selecting which adjuvant therapy (chemotherapy or radiation therapy) to use. Cleft lip and palate transmembrane protein 1-like protein (CLPTM1L; also known as cisplatin resistance-related protein 9) is associated with apoptotic mechanisms and is related to the proliferation of the tumor cells and resistance against chemotherapy. In the present study, the association between CLPTM1L expression and recurrence of intermediate- and high-risk stage IB-IIB cervical cancer in patients undergoing radical hysterectomy followed by treatment with cisplatin and paclitaxel (TP) as adjuvant chemotherapy was determined. Patients were divided into two groups: Recurrence group and no-recurrence group. CLPTM1L expression was examined using immunohistochemistry in paraffin-embedded sections using weighted scores. Regarding the characteristics of the patients, a histology of non-squamous cell carcinoma, lymph node metastasis and parametrium invasion were more common in the recurrence group compared with the non-recurrence group. In the recurrence group, CLPTM1L expression was significantly higher than that in the no-recurrence group. Next, patients were divided into low and high-expression groups based on the weighted score with a cut-off value of 6. In the high expression group, patients exhibited a higher rate of recurrence (37.5 vs. 5.1%) and had worse overall survival. Multivariate analysis revealed that high CLPTM1L expression was independently related to recurrence. In in vitro analysis, small interfering RNA-mediated knockdown of CLPTM1L enhanced the sensitivity of cervical cancer cells to cisplatin. In conclusion, the present study revealed that CLPTM1L expression may be a predictive biomarker of recurrence of intermediate- and high-risk stage IB-IIB cervical cancer in patients undergoing radical hysterectomy followed by TP as adjuvant chemotherapy.

Altered offspring neurodevelopment in an L-NAME-induced preeclampsia rat model.

Introduction: To investigate the mechanism underlying the increased risk of subsequent neurodevelopmental disorders in children born to mothers with preeclampsia, we evaluated the neurodevelopment of offspring of a preeclampsia rat model induced by the administration of N-nitro-L-arginine methyl ester (L-NAME) and identified unique protein signatures in the offspring cerebrospinal fluid. Methods: Pregnant rats received an intraperitoneal injection of L-NAME (250 mg/kg/day) during gestational days 15-20 to establish a preeclampsia model. Behavioral experiments (negative geotaxis, open-field, rotarod treadmill, and active avoidance tests), immunohistochemistry [anti-neuronal nuclei (NeuN) staining in the hippocampal dentate gyrus and cerebral cortex on postnatal day 70], and proteome analysis of the cerebrospinal fluid on postnatal day 5 were performed on male offspring. Results: Offspring of the preeclampsia dam exhibited increased growth restriction at birth (52.5%), but showed postnatal catch-up growth on postnatal day 14. Several behavioral abnormalities including motor development and vestibular function (negative geotaxis test: p < 0.01) in the neonatal period; motor coordination and learning skills (rotarod treadmill test: p = 0.01); and memory skills (active avoidance test: p < 0.01) in the juvenile period were observed. NeuN-positive cells in preeclampsia rats were significantly reduced in both the hippocampal dentate gyrus and cerebral cortex (p < 0.01, p < 0.01, respectively). Among the 1270 proteins in the cerebrospinal fluid identified using liquid chromatography-tandem mass spectrometry, 32 were differentially expressed. Principal component analysis showed that most cerebrospinal fluid samples achieved clear separation between preeclampsia and control rats. Pathway analysis revealed that differentially expressed proteins were associated with endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins, which are involved in various nervous system disorders including autism spectrum disorders, schizophrenia, and Alzheimer's disease. Conclusion: The offspring of the L-NAME-induced preeclampsia model rats exhibited key features of neurodevelopmental abnormalities on behavioral and pathological examinations similar to humans. We found altered cerebrospinal fluid protein profiling in this preeclampsia rat, and the unique protein signatures related to endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins may be associated with subsequent adverse neurodevelopment in the offspring.

New-onset postpartum hypertension in women without a history of hypertensive disorders of pregnancy: a multicenter study in Japan.

The aim of this study was to investigate the prevalence and risk factors of new-onset postpartum hypertension (PPHTN), defined as new-onset hypertension during the postpartum period, among women without a history of hypertension during pregnancy and labor. A multicenter retrospective study was conducted using clinical data of women who delivered at term between 2011 and 2018 at 12 maternity hospitals. A total of 18,295 normotensive women were eligible, after excluding those with hypertensive disorders of pregnancy or hypertension during labor. New-onset PPHTN was defined as multiple blood pressure readings of ≥ 140/90 mmHg between 1 d and 4 weeks postpartum among normotensive women throughout pregnancy. Multivariate regression analyses were performed to evaluate the risk factors for new-onset PPHTN. Among the 18,295 normotensive women, 227 (1.2%) presented with new-onset PPHTN. The prevalence was higher in women who delivered via cesarean section than in those who delivered vaginally (7.0% and 1.0%, respectively). The independent risk factors were maternal age ≥ 35 years (adjusted odds ratio 1.67, 95% confidence interval [1.10-2.53]), nulliparity (1.83 [1.24-2.71]), high normal blood pressure (systolic blood pressure [SBP] 120-129 and diastolic blood pressure [DBP] < 80) at the last prenatal check-up (1.96 [1.23-3.13]), elevated blood pressure (SBP 130-139 and/or DBP 80-89) (6.42 [4.15-9.95]), urinary protein 1+ (1.99 [1.27-3.11]), scheduled cesarean section (4.05 [1.69-9.69]), and emergency cesarean section (10.02 [5.10-19.70]). New-onset PPHTN was observed in 1.2% of the normotensive women, with women who delivered via cesarean section having the highest risk. Close postpartum blood pressure monitoring may be required for women with multiple risk factors to identify new-onset PPHTN in a timely manner and reduce adverse maternal consequences.
