Vertical transmission of methicillin-resistant Staphylococcus aureus at delivery and its clinical impact: An observational, prospective cohort study.

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) infection has a significant clinical impact on both pregnant women and neonates. The aim of this study was to assess accurately the vertical transmission rate of MRSA and its clinical impacts on both pregnant mothers and neonates. MATERIAL AND METHODS: We conducted a prospective observational cohort study of 898 pregnant women who were admitted to our department and 905 neonates from August 2016 to December 2017. MRSA was cultured from nasal and vaginal samples taken from the mothers at enrollment and from nasal and umbilical surface swabs taken from neonates at the time of delivery. We examined the vertical transmission rate of MRSA in mother-neonate pairs. We used multivariable logistic regression to identify risk factors for maternal MRSA colonization and maternal/neonatal adverse outcomes associated with maternal MRSA colonization. RESULTS: The prevalence of maternal MRSA colonization was 6.1% (55 of 898) at enrollment. The independent risk factors were multiparity and occupation (healthcare provider) (odds ratio [OR] 2.35, 95% confidence interval [CI] 1.25-4.42 and OR 2.58, 95% CI 1.39-4.79, respectively). The prevalence of neonatal MRSA colonization at birth was 12.7% (7 of 55 mother-neonate pairs) in the maternal MRSA-positive group, whereas it was only 0.12% (one of 843 pairs) in the maternal MRSA-negative group (OR 121, 95% CI 14.6-1000). When maternal vaginal samples were MRSA-positive, vertical transmission was observed in four of nine cases (44.4%) in this study. Skin and soft tissue infections developed more frequently in neonates in the maternal MRSA-positive group than in the MRSA-negative group (OR 7.47, 95% CI 2.50-22.3). CONCLUSIONS: The prevalence of MRSA in pregnant women was approximately 6%. Vertical transmission caused by maternal vaginal MRSA colonization was observed in four of nine cases (44.4%). Although our study includes a limited number of maternal MRSA positive cases, the vertical transmission of MRSA may occur in up to 44% of neonates of mothers with vaginal MRSA colonization. Maternal MRSA colonization may be associated with increased development of skin and soft tissue infections in neonates via vertical transmission.

A novel classification of glucose profile in pregnancy based on continuous glucose monitoring data.

AIM: To investigate the glucose profile of women with and without gestational diabetes mellitus (GDM) by simultaneously analyzing several factors of continuous glucose monitoring (CGM) data. METHODS: CGM was conducted for 2 weeks in the second trimester of pregnant women whose random blood glucose level was ≥100 mg/dl. A 75-g oral glucose tolerance test was performed around day 7, and the index of hyperglycemia, relative hypoglycemia, and indices of glucose variability were extracted from CGM data. Unsupervised hierarchical clustering was performed to categorize glucose profiles of the participants. RESULTS: CGM data were obtained from 29 women. Glucose profiles were categorized into three clusters: low glucose levels with less glucose variability group (L group, n = 7); moderate glucose levels with moderate-to-high glucose variability group (M group, n = 18); and high glucose levels with high glucose variability group (H group, n = 4). The waveforms of the glucose profiles were very different among the three groups. Women with GDM tended to be more frequent in the H group than in the M and L groups (75.0%, 16.7%, and 14.3%, respectively; p = 0.053). Maternal age was significantly higher and the proportion of multiparous women was significantly larger in the H group compared to L group (p = 0.002 and 0.015, respectively). CONCLUSIONS: A comprehensive analysis of CGM data could help us extract a subgroup of women with characteristics of GDM.

Acceptance and commitment therapy combined with vestibular rehabilitation for persistent postural-perceptual dizziness: A pilot study.

PURPOSE: This study investigated the feasibility of acceptance and commitment therapy for persistent postural-perceptual dizziness and preliminarily verified the long-term effectiveness of the therapy. MATERIALS AND METHODS: This study implemented the within-group pre-post comparison design. We enrolled 27 adult patients who met the criteria of persistent postural-perceptual dizziness. They underwent a treatment program including acceptance and commitment therapy combined with vestibular rehabilitation once a week for a total of six sessions. The primary outcome was changes in the Dizziness Handicap Inventory score 6 months posttreatment. RESULTS: All 27 patients completed the acceptance and commitment therapy + vestibular rehabilitation program, and 25 patients (92.6%) could be followed for 6 months posttreatment. For 27 participants, the scores from pretreatment to 6 months posttreatment significantly declined (P < .001), and the Dizziness Handicap Inventory effect size was 1.11 (95% confidence interval = 0.80-1.42). At 6 months posttreatment, 11 patients (40.7%) achieved remission (the score ≤ 14), 16 (59.3%) achieved treatment response (reduction in the score ≥ 18), and 20 (74.1%) achieved remission and/or treatment response. CONCLUSIONS: Acceptance and commitment therapy is feasible for persistent postural-perceptual dizziness and might have long-term effectiveness. However, a randomized controlled trial is warranted.

Two cases of Wolffian tumor with novel magnetic resonance imaging findings reflecting characteristic pathology.

A Wolffian tumor is a rare tumor arising from the remnants of the mesonephric duct. Herein, we report two cases. A 61-year-old woman presented with swollen left adnexa. On T2 weighted magnetic resonance imaging (MRI), a 4.4 cm solid pelvic mass showed slightly high signal intensity, with a low-signal-intensity rim. Microscopically, cuboidal cells with bland nuclei were arranged in a dense tubular form. A 40-year-old woman complained of lower abdominal pain. On T2 weighted MRI, a 6.0 cm solid mass with a low-signal-intensity rim was found. The pathology of the resected tumor was similar to that of case 1. Both cases were diagnosed as Wolffian tumor. The rims of the tumors in both cases were composed of eosinophilic spindle-shaped cells immunoreactive to alpha-smooth muscle actin and desmin, identical to the smooth muscle cells surrounding the mesonephric duct remnants. MRI findings reflecting smooth muscle rims might contribute to an accurate preoperative diagnosis of this rare tumor.

Randomised controlled trial of cultural-adapted and programme-adopted cognitive behavioural therapy for children and adolescents' anxiety in Japan: protocol for a Multi-, Inter-, and Cross-cultural Clinical Child Study (MIXCS).

INTRODUCTION: The primary objective of the Multi-, Inter-, and Cross-cultural Clinical Child Study (MIXCS) is to evaluate the hypothesis that the effects of cultural-adapted cognitive behavioural therapy (CA-CBT) and programme-adopted cognitive behavioural therapy (PA-CBT) for children and adolescents' anxiety are both superior to a psychological control (moral education control: MEC) for reducing child and adolescent anxiety disorders and symptoms as well as related constructs. The secondary objective is to explore commonalities and differences in therapy factors between CA-CBT and PA-CBT. METHOD AND ANALYSIS: The study has been designed as a randomised, controlled and assessor masked multicentre superiority trial with three groups: CA-CBT, PA-CBT and MEC. Primary outcome is remission of primary anxiety disorders evaluated by independent evaluators. Secondary outcomes are clinician's severity ratings, child self-reported anxiety symptoms, depressive symptoms, cognitive errors and family accommodation, as well as parent-reported anxiety symptoms, and family accommodation. Competence and adherence of treatment, therapy factors in treatment sessions are also measured based on behavioural observation. Finally, satisfaction and comprehension are collected. We aim to recruit at least 99 families for the analysis. Treatment will be delivered weekly for 10 sessions and assessment will be conducted 2 weeks before the treatment (pre), 3 months after the base date when the treatment starts (post), 6 months (six months follow-up) and 12 months (12 months follow-up) after the postassessment. ETHICS AND DISSEMINATION: The MIXCS study was approved by Doshisha University Research Ethics Review Committee, Kwansei Gakuin University Institutional Review Board for Medical and Biological Research Involving Human Subjects and Shinshu University Certified Review Board of Clinical Research. Regardless of the results, the primary outcome will be published in a journal, and if the efficacy and effectiveness of CA-CBT and/or PA-CBT are empirically supported, the authors will encourage dissemination of the programmes including the assessment system through key stakeholders in education, health, and welfare areas. TRIAL REGISTRATION NUMBER: UMIN000038128.

Clinical impact of age­specific distribution of combination patterns of cytology and high­risk HPV status on cervical intraepithelial neoplasia grade 2 or more.

To the best of our knowledge, the present study is the first to elucidate the significance of cytology and high-risk human papillomavirus (hrHPV) status in different age groups for the detection of cervical intraepithelial neoplasia (CIN)2, CIN3 and squamous cell carcinoma (SCC). There were 12 combinations based on cytology and hrHPV status [cytology: Atypical squamous cells (ASC) of undetermined significance, low-grade squamous intraepithelial lesion, ASC not excluding high-grade squamous intraepithelial lesion (HSIL) and HSIL; hrHPV status: HPV16/18-positive (16/18+), hrHPV positive for subtypes other than 16/18 (others+) and hrHPV-negative (hrHPV-)]. All patients were categorized into four groups based on age (18-29, 30-39, 40-49 and ≥50 years). For patients with CIN2, CIN3 and SCC (CIN2+) (n=107), the distribution of cytology and hrHPV was investigated in each age group. In addition, for all patients (n=446), the occurrence of CIN2+ in each of the 12 combinations was investigated in each age group. In the 18-29-year age group, the most common combination was HSIL and 16/18+, followed by HSIL and others+, which accounted for 73% of CIN2+ cases. The occurrence of HSIL and 16/18+ decreased with increasing age, and no cases occurred in the 50-year age group. In the 18-29-year age group, all patients with HSIL and 16/18+ were diagnosed with CIN2+. CIN2+ was predominantly detected in patients with HSIL in the 18-29-year age group, as well as hrHPV- and others+. This definite distinction was not observed in any other age group. For CIN2+, the distribution patterns of cytology and hrHPV status combinations varied significantly among different age groups. Accordingly, the clinical impact of the combination of cytological findings and hrHPV status can vary among age groups.

Association of Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder Traits with Depression and Empathy Among Medical Students.

PURPOSE: This study aimed to investigate the associations of the traits of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) with depression and empathy among medical students. PATIENTS AND METHODS: A cross-sectional survey was conducted with 202 fifth-year students at a Japanese medical school for 10 months during their clinical clerkship. The survey included sociodemographic questions and validated tools to measure depressive symptoms (Hospital Anxiety and Depression Scale [HADS]), medical students' empathy for patients (Jefferson Scale of Empathy-Student version [JSE]), ADHD traits (ADHD Self-Report Scale Screener [ASRS Screener]), and ASD traits (Autism-Spectrum Quotient Japanese version-21 [AQ-J-21]). RESULTS: A total of 151 students (response rate: 74.7%) participated in the survey. Of these, 41 (27.2%) reported a total score of ≥ 20 on the HADS and were categorized as depressed. Depressed students reported significantly lower and higher rates of having a part-time job and a history of enrolment in other faculties, respectively, than non-depressed students. According to the cutoff criteria of the ASRS Screener and AQ-J-21, 31 (20.5%) and 42 (27.8%) students reported ADHD and ASD traits, respectively. Multivariate regression analysis, controlling for age and sex, reported that higher age, ASRS Screener scores, and AQ-J-21 scores were significant predictors of higher HADS total scores. Additionally, higher AQ-J-21 scores significantly predicted lower JSE scores. CONCLUSION: The degree of ADHD and ASD traits was significantly associated with depression. Moreover, the degree of ASD traits was significantly associated with lower empathy for their patients. It is important to consider that about 20-30% of medical students have these neurodevelopmental traits and to develop intervention strategies for improving depression and empathy.

A Case of Recurrent Hemorrhagic Corpus Luteum with Elevated Follicle-Stimulating Hormone, Controlled by Estrogen/Gestagen Therapy.

A high secretion of follicle-stimulating hormone (FSH) in reproductive-aged women is unusual. We report a case of recurrent corpus luteum hemorrhage and subsequent ovarian torsion with markedly elevated FSH levels in a reproductive-aged woman in the absence of functional gonadotroph adenoma (FGA) or premature ovarian failure (POF). A 22-year-old nulligravid woman with a history of bilateral hemorrhagic corpus luteum and subsequent ovarian torsion presented with acute abdominal pain. An emergency salpingo-oophorectomy of the right side was performed, and the right ovarian torsion due to hemorrhagic corpus luteum was diagnosed. Laboratory tests revealed markedly elevated FSH levels (77.6 mIU/mL). FGA was suspected, but no evidence of tumor was identified. The left ovary enlarged again at one-month follow-up. Estrogen/gestagen therapy (EGT) was started, which reduced the enlarged ovary to normal size. Two years later, her pituitary hormonal status was evaluated in detail. Besides markedly elevated FSH level, slightly elevated LH (31.2 mIU/mL), normal total inhibin B (35.3 pg/ml), abnormally low anti-Müllerian hormone (AMH) (<0.03 ng/mL), and poor FSH response to gonadotropin-releasing hormone stimulation test were found. In the absence of FGA, we conclude that certain disorders of inhibitory factors for FSH function, including inhibin and AMH may exist, which could attribute to the patient's symptoms. EGT was very effective in suppressing the ovarian hyperactivity.

A randomized controlled trial of a bidirectional cultural adaptation of cognitive behavior therapy for children and adolescents with anxiety disorders.

BACKGROUND: Cognitive behavior therapy (CBT) programs with ethnic and cultural sensitivity are scarce. This study was the first randomized controlled trial of cognitive behavior therapy for children and adolescents with anxiety disorders using bidirectional cultural adaptation. METHODS: The Japanese Anxiety Children/Adolescents Cognitive Behavior Therapy program (JACA-CBT) was developed based on existing evidence-based CBT for anxious youth and optimized through feedback from clinicians in the indigenous cultural group. Fifty-one children and adolescents aged 8-15 with anxiety disorders were randomly allocated to either a cognitive behavioral treatment (CBT: 122.08 days, SD = 48.15) or a wait-list control condition (WLC: 70.00 days, SD = 11.01). Participants were assessed at pre-treatment and post-treatment as well as 3 and 6 months after completion of treatment (92.88 days, SD = 17.72 and 189.42 days, SD = 25.06) using a diagnostic interview, self-report measures of anxiety, depression, cognitive errors, and a parent-report measure of anxiety. RESULTS: A significant difference was found between the CBT and WLC at post-treatment, specifically 50% of participants in the treatment condition were free from their principal diagnoses compared to 12% in the wait-list condition, χ2 (1, N = 51) = 8.55, η2 = 0.17, p < .01. In addition, participants in the treatment condition showed significant improvement in clinical severity and child-self reported depression, F (1, 49) = 12.38, p < .001, F (1, 47.60) = 5.95, p < .05. At post-treatment, Hedge's g between the conditions was large for clinical severity, 1.00 (95% CI = 0.42-1.58), and moderate for the self-report anxiety scale, 0.43 (0.19-1.04), two depression scales, 0.39 (0.22-1.00), 0.48 (0.14-1.09), and the cognitive errors scale, 0.38 (0.24-0.99). Finally, significant improvements in diagnostic status were evident at the 3 and 6-month follow-up assessments when combining the CBT and WLC, ps < .001. CONCLUSION: The current results support the transportability of CBT and the efficacy of a bidirectional, culturally adapted cognitive behavior therapy in an underrepresented population.

A Case of Synchronous Primary Corpus and Ovarian Cancer with Pseudo-Meigs Syndrome: Utilization of a Diagnostic Laparoscopy for the Accurate Diagnosis.

We report a case of synchronous primary corpus and ovarian cancer (SPC) with massive ascites due to Pseudo-Meigs syndrome (PMS). A 48-year-old woman presented with complaints of abnormal genital bleeding and abdominal discomfort. Massive ascites and tumors in the endometrium and right ovary were detected. Although imaging tests showed no evidence of dissemination, and ascites cytology was negative, we performed a diagnostic laparoscopy to exclude the possibility of microdissemination because pathological findings of the corpus tumor were suggested to be so-called Type-2 endometrial cancer. Laparoscopy clearly confirmed no dissemination in the peritoneum. We ultimately diagnosed this patient with SPC with massive nonmalignant ascites due to PMS and performed an appropriate treatment. This report is the first case of SPC that developed PMS.

A Case of Pregnancy Complicated with ATIII Deficiency in a Patient Who Developed Severe Venous Thromboembolism in Her Fourth Pregnancy and Had a Favourable Outcome in Her Subsequent Pregnancy with Careful Management of Anticoagulation Therapy including Edoxaban.

Congenital ATIII deficiency is one of the congenital thrombophilia diseases that can cause severe venous thromboembolism (VTE) in pregnant patients. A 30-year-old female, 4 gravida and 2 para, came to the emergency department with a complaint of oedema and pain in the left lower leg at 11 weeks of gestation. An inferior vena cava thrombus and pulmonary embolism were found. Because VTE was very severe, artificial abortion was performed, and VTE disappeared rapidly. She maintained oral administration of edoxaban (NOAC) and got pregnant naturally fifty-five weeks later after the abortion. Anticoagulation therapy was changed from NOAC to ATIII formulation and unfractionated heparin at 5 weeks of gestation. The course of pregnancy was good, and a healthy female newborn of 2310 g was delivered vaginally at 37 weeks 6 days of gestation. In puerperium, anticoagulation therapy was changed to warfarin. Currently one and one-half years had passed after delivery and no major adverse events or thrombosis has occurred. This case indicates that severe VTE can develop even in multipara pregnancy and that those who take NOAC may be able to continue pregnancy when they get pregnant.

A Case of Pregnancy Complicated with Evans Syndrome with Sequential Development of Autoimmune Warm Antibody Hemolytic Anemia and Idiopathic Thrombocytopenic Purpura.

The simultaneous or sequential development of autoimmune hemolytic anemia (AIHA) and idiopathic thrombocytopenic purpura (ITP) is known as Evans syndrome. We experienced a case of Evans syndrome that developed AIHA during pregnancy and ITP long after delivery. The patient was a 35-year-old pregnant woman (gravida 2, para 1). A routine blood test at 28 weeks of gestation revealed moderate macrocytic anemia. Her haptoglobin level was markedly low, and a direct antiglobulin test (DAT) was positive. Based on these results, AIHA was considered. A healthy female newborn with bodyweight 3575 g was vaginally delivered uneventfully. After delivery, the DAT remained positive, but anemia did not develop. At 203 days after delivery, ITP was detected. Because AIHA and ITP developed sequentially, she was diagnosed with Evans syndrome. When AIHA occurs during pregnancy, long-term follow-up is needed because ITP can develop sequentially.

Gliomatosis peritonei with 18F-fluorodeoxyglucose accumulation and contrast enhancement secondary to immature teratoma: A case report.

Gliomatosis peritonei (GP) is a rare condition characterized by mature glial tissue implants widespread in the peritoneum, which is occasionally followed by treatment for immature teratoma (IM). The present study reported a case of GP with fluorodeoxyglucose (FDG) accumulation and contrast enhancement followed by treatment for IM. A 30-year-old female, 2-gravida and 0-para, underwent laparotomy with hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy followed by four cycles of chemotherapy with bleomycin, etoposide, and cisplatin for IM (Grade 2) of stage IIIC. At the 6-month follow-up, computed tomography (CT) revealed a 1-cm mass with contrast enhancement on splenic flexure. Positron-emission tomography (PET)/CT revealed intense FDG accumulation at the same site. Although α-fetoprotein, which was elevated preoperatively, remained normal, she was diagnosed with IM recurrence. The patient underwent three cycles of chemotherapy with paclitaxel, ifosfamide, and cisplatin, but the size, the degree of contrast enhancement and FDG accumulation of the mass did not change after chemotherapy. A diagnostic laparoscopy was performed. which revealed multiple small peritoneal implants, including a 1-cm mass at the splenic flexure. The 1-cm mass was dissected at the splenic flexure and some other implants. Mature well-differentiated glial tissue with non-atypia was identified in all tissue, and a diagnosis of GP was made. The patient is currently undergoing regular follow-up. Few reports are available regarding FDG-PET/CT imaging of GP. GP should be considered as the differential diagnosis of FDG-avid mass followed by IM therapy. A laparoscopic diagnosis is useful to obtain an accurate diagnosis of GP.

Occurrence of Lectin in the Silkgland of the Silkworm, Bombyx mori: (lectin/silkgland/hemolymph).

Monoclonal antibodies were prepared against the 350 kDa lectin purified from larval hemolymph of the silkworm, Bombyx mori. The antibodies inhibited the hemagglutinating activity (HA activity) and bound specifically to the hemolymph 350 kDa lectin on Western blotting analysis. Immunohistological observations revealed the occurrence of lectin in the cuticular intima of the anterior silk gland, but not the middle or posterior silk glands of fifth instar larvae of Bombyx mori. Extracts from the anterior silk glands showed HA activity and exhibited the same biochemical characteristics as those of the 350 kDa lectin in the hemolymph. These results suggested that lectin-like molecules in epithelial tissues may be important in histolysis during molting and metamorphosis.
