Influence of smoking habits on mental status in Japanese women during the first trimester of pregnancy.

Purpose: We examined the relation between smoking habits and maternal mental status such as depression and anxiety during the first trimester of pregnancy.

Material And Methods: Between July 2016 and June 2018, we examined the increased odds of depressive and anxiety symptoms in the women with smoking habits during prepregnancy with and without smoking cessation during the first trimester of pregnancy in comparison with those without smoking habits using self-administered questionnaires.

Results: The rate of depressive and anxiety symptom in the women with smoking habits during prepregnancy (46.

Current prevalence of and obstetric outcomes in underweight Japanese women.

We compared the current prevalence of and obstetric outcomes in underweight Japanese women with data from 16 years ago. We reviewed the obstetric records of singleton pregnant Japanese women who delivered at our institute at ≥ 22 weeks' gestation from 2000 through 2002 and those from 2016 through 2018. From 2000-2002 to 2016-2018, numbers of pregnant women in their twenties decreased and pregnant women in their forties increased significantly (p < 0.

The impact of rotating work schedules, chronotype, and restless legs syndrome/Willis-Ekbom disease on sleep quality among female hospital nurses and midwives: A cross-sectional survey.

Background: Decreases in subjective sleep quality are prevalent among nurses and midwives engaged in rotating shift work.

Objectives: The present study aimed to examine the relationship between differences in work schedules and subjective sleep quality among female nursing staff.

Design: A cross-sectional survey design was used for descriptive and logistic regression analyses.

Factors associated with the development of spontaneous intertwin membrane separation in dichorionic twin pregnancy.

Objective: We examined factors associated with the development of spontaneous intertwin membrane separation in dichorionic twin pregnancy.

Methods: Medical charts of 618 dichorionic twin pregnancies without the history of amniocentesis managed after 22 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2017 were reviewed.

Results: Twenty-four cases (3.

Trends in obstetric policies in cases of failed vacuum extraction in Japan.

In April 2008, the guidelines for obstetric practice in Japan have made the following recommendations: (1) do not use vacuum extraction (VE) for more than 20 min, and consider forceps delivery (FD) or an emergency cesarean section (CS) if necessary (20-minute VE trial rule), and (2) do not try VE more than five times, even if VE has been used for less than 20 min (5-time VE trial rule). The aims of the present study were to compare the obstetric policies related to failed VE before and after 2008. We reviewed the obstetric records of all cases of VE in cases of singleton pregnancy with a neonatal birth weight ≥ 2500 g beyond 37 weeks' gestation at our hospital from April 2002 to March 2014.

Cardiotocography findings of early-stage chronic fetomaternal hemorrhage after the presentation of reduced fetal movement.

In the current case of fetomaternal hemorrhage with reduced fetal movements, the findings of cardiotocography (CTG) seemed to be indicating reassuring fetal status; however, a late deceleration and sinusoidal heart rate (SHR)-like findings were observed following a weak uterine contraction. Altogether, this case indicates that the presence of reduced fetal movements may precede the appearance of SHR patterns on CTG in cases of chronic fetomaternal hemorrhage.

Excessively long umbilical cord: a preventive factor of miserable outcomes of pregnancies with true umbilical cord knots.

We examined the clinical significance of pregnancies with true umbilical cord knots related to umbilical cord length. The material reviewed consisted of the total population of Japanese women who gave birth to singleton babies at 34-41 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2017. During the study period, there were 32,315 Japanese women who gave birth to singleton babies at 34-41 weeks' gestation.

Current status of Neisseria gonorrhoeae cervicitis in pregnant women in Japan.

We evaluated the current prevalence of gonococcal cervicitis among pregnant women in institutes that either do or do not routinely screen for gonococcal infection in Japan. We requested 2,330 obstetrical facilities to provide information on Neisseria gonorrhoeae cervicitis in pregnant women. A total of 1,876 (80.

Comparison of the Edinburgh Postnatal Depression Scale and the Whooley questions in screening for postpartum depression in Japan.

We examined the clinical utility of the Whooley questions in comparison with that of the Edinburgh Postnatal Depression Scale (EPDS) in Japan. We carried out mental health screening of all postnatal mothers ( = 258) who gave birth to singleton babies at term attending our hospital using the EPDS and the Whooley questions. For the EPDS, scores were calculated, and a score of nine points or more was regarded as "positive screening" according to the results of previous observations in Japan.

Association between clinical chorioamnionitis and histological funisitis at term.

To predict the presence of histological funisitis at term, we examined the symptoms of clinical chorioamnionitis in 251 cases of maternal fever of 38 degrees or higher during labor at term. The examined symptoms in this study were clinical maternal findings (uterine fundal tenderness, maternal tachycardia, purulent or foul amniotic fluid or cervical discharge, and maternal white blood cell count) and fetal tachycardia. In these cases, microscopic histopathological analysis of the placenta was performed after delivery.

Risk factors for postpartum urinary retention after vaginal delivery at term without epidural anesthesia.

We performed a retrospective case-control study of vaginal delivery at term without epidural anesthesia to identify clinical predictions of postpartum urinary retention (PUR). We reviewed the obstetric records of all singleton vaginal deliveries at Japanese Red Cross, Katsushika Maternity Hospital form January 2016 through December 2017. There were 58 women (2.

Clinical significance of pregnancy in adolescence in Japan.

Objective: We examined the clinical characteristics and obstetric outcomes in adolescent pregnancies in Japanese women.

Methods: The present study was a retrospective investigation of all primiparous Japanese women with singleton pregnancies who gave birth at ≥22 weeks' gestation aged ≤18 years old (adolescent pregnancy, n = 325) and aged 28-30 years old (n = 2029) at Japanese Red Cross, Katsushika Maternity Hospital between 2002 and 2016.

Results: The frequencies of smoking, economic problems, an unmarried single status at delivery and the start of prenatal care in the first trimester in the adolescent pregnancy group were significantly higher than in the control group (p < .

Recent Reason for Hindering Medications for Perinatal Mental Disorders in Japan.

Background: We examined the recent reasons for hindering antipsychotic medications during pregnancy in Japan.

Methods: We retrospectively analyzed the medical charts of all women who gave birth after 22 weeks' gestation at Japanese Red Cross Katsushika Maternity Hospital from August 2016 to July 2017.

Results: Four pregnant women with mental disorders (three schizophrenia and one adjustment disorder) kept the interruption of medications under their partners' compulsion.

Obstetric Outcomes of Twin Pregnancies in Japanese Women Aged 40 and Older.

Background: The aim of this study was to compare the obstetric outcomes of twin pregnancies between Japanese women aged ≥ 40 years and their younger counterparts aged 25 - 29.

Methods: This was a retrospective study of twin pregnancies managed at Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2016. Women aged 40 and older at delivery (n = 117) were compared with women aged 25 - 29 at delivery (n = 536).
