Abstract
AbstractPersonality has been shown to predict postpartum depressive symptoms (PDS) assessed by the Edinburgh Postnatal Depression Scale (EPDS). However, existing studies have not considered the underlying symptom dimensions in the EPDS. We analyzed data from 15,012 women who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Personality was assessed in middle pregnancy using the short-form Eysenck Personality Questionnaire-Revised. PDS were defined as EPDS score ≥ 9 at 1 month after delivery. The EPDS items were further divided into three dimensions: depressed mood, anxiety, and anhedonia. Multiple analyses were conducted to examine the associations of each personality scale with PDS and three dimensions in the EPDS, adjusting for age, parity, mode of delivery, education, income, and social isolation. The prevalence of PDS assessed by the EPDS at 1 month after delivery was 13.1%. Higher neuroticism scores were associated with PDS (odds ratio [OR], 2.63; 95% confidence interval [CI], 2.48 to 2.79) and all three dimensions (all p < 0.001). Lower extraversion scores were associated with PDS (OR, 0.74; 95% CI, 0.70 to 0.78) and all three dimensions (all p < 0.001). Lower psychoticism scores were associated with PDS (OR, 0.89; 95% CI, 0.85 to 0.94) and anxiety (p < 0.001), but not with depressed mood (p = 0.20) or anhedonia (p = 0.92). In conclusion, higher neuroticism and lower extraversion were associated with PDS and the three underlying dimensions in the EPDS, while lower psychoticism was associated with anxiety, but not with depressed mood or anhedonia.

Cumulative exposure to maternal psychological distress in the prenatal and postnatal periods and atopic dermatitis in children: findings from the TMM BirThree Cohort Study. BMC Pregnancy Childbirth 2022; 22:242.

Abstract
Background Maternal mental health problems in each of the prenatal period and postnatal period have been demonstrated as possible risk factors for atopic dermatitis (AD) in children. However, the cumulative impacts of maternal psychological distress in the prenatal and postnatal periods on AD in children remain unclear. This study examined the association between cumulative exposure to maternal psychological distress in the prenatal and postnatal periods and the development of AD in children. Methods Data were derived from the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study in Japan. In total, 8377 mother-child pairs in which the child had no AD at the age of 1 year were analyzed. Maternal psychological distress in early pregnancy and 1 year after delivery was defined as a K6 score ≥ 5, and the participants were categorized into four groups: no psychological distress in both the prenatal and postnatal periods; only the prenatal period; only the postnatal period; and both periods. The development of AD was defined as the presence of AD in a 2-year-old child without AD reported at the age of 1 year using the International Study of Asthma and Allergies in Childhood questionnaire. Generalized linear model analyses were conducted to examine the association between maternal psychological distress and the development of AD in children adjusted for age at delivery, educational attainment, smoking status in pregnancy, maternal history of AD, paternal history of AD, parity, maternal body mass index, and child sex. Results Between the ages of 1 and 2 years, 14.0% of children developed AD. Maternal psychological distress in both prenatal and postnatal periods was associated with an increased risk of AD in children compared to no psychological distress in both periods (relative risk (RR), 95% confidence interval (CI): 1.34, 1.20–1.47). Maternal psychological distress in only the postnatal period was associated with an increased risk of AD in children (RR, 95% CI: 1.23, 1.07–1.39), but not in only the prenatal period (RR, 95% CI: 1.14, 0.98–1.30). Conclusions Cumulative exposure to maternal psychological distress in the prenatal and postnatal periods was associated with the development of AD in children.

Abstract
Infectious diseases, chronic diseases, and mental disorders in both adults and children are reported after disasters occur. The correlation between chronic diseases and mental disorders has also been reported. Moreover, disasters may affect perinatal outcomes. Thus, both adult and child health should be carefully monitored in disaster aftermath. A prospective cohort study of pregnant women and their families, the Tohoku Medical Megabank Project (TMM) Birth and Three-Generation Cohort Study (TMM BirThree Cohort Study), has been conducted since 2013. A total of 73,529 family members participated in the TMM BirThree Cohort Study. Among siblings, the proportion of "small for gestational age" was the same in the pre- and post-disaster periods. Among parents and grandparents who answered the baseline questionnaire, 5.6% in the inland area and 19.8% in the coastal area had their houses totally/mostly destroyed by the Great East Japan Earthquake. Although a depression trend due to house damage was not observed in mothers, the proportion of psychological distress was high according to house damage (P for trend = 0.04). Among parents, there was an increase in overweight persons (P for trend = 0.004 in mothers and < 0.0001 in fathers) and in the number of smokers based on the severity of house damage (P for trend = 0.002 in mothers and < 0.0001 in fathers), whereas no such trend was observed in grandparents. Continuous monitoring and support for those who need are essential. Moreover, utilizing existing cohort studies to investigate health status when we face a new disaster is desirable.

Abstract
No studies have examined the association of the combination of n-3 polyunsaturated fatty acids (PUFAs) and n-6 PUFAs intake with psychological distress during pregnancy. To examine these associations, we divided Japanese pregnant women into 25 groups based on combining quintiles of n-3 PUFAs intake and quintiles of n-6 PUFAs intake. We conducted multivariable logistic regression analyses to assess the risk of psychological distress during pregnancy (Kessler Psychological Distress Scale ≥ 5 or 13). Compared to the third quintile of both n-3 PUFAs and n-6 PUFAs intake, the groups with unbalanced intake, high intake of both, and low intake of both were associated with a higher risk of both Kessler Psychological Distress Scale ≥ 5 and 13 in early and mid-pregnancy. Further research is needed to identify the precise combination of n-3 PUFAs and n-6 PUFAs intake associated with the lowest psychological distress during pregnancy.

Abstract
BACKGROUND AND OBJECTIVES Although large-scale natural disasters and the resultant changes in living environments worsen dietary habits among adults immediately after the disasters, whether this association remains for a long period is unclear. This is particularly important for recent mothers because lactating women require additional nutrition for milk production. Thus, we investigated the association of living environments with dietary habits and nutritional intake of recent mothers between four and seven years after the Great East Japan Earthquake (11th March, 2011). METHODS AND STUDY DESIGN We analyzed 8,551 mothers who participated to the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Living environments were characterized into four categories: "same home before the earthquake", "rental housing", "reconstructed home", and "acquaintance's home". Dietary habits and nutritional intake were evaluated using a food frequency questionnaire answered 12 months after their deliveries (the questionnaire was answered between March 2015 and July 2018). RESULTS Multiple linear regression analyses demonstrated that mothers in 'rental housing' or 'reconstructed home' had a significantly lower intake of almost all nutrients or certain nutrients, respectively, compared with those residing in 'same home before the earthquake'. However, fewer significant differences were detected between the nutritional intake of the mothers lodging in an 'acquaintance's home' and that of those living in 'same home before the earthquake'. CONCLUSIONS Our findings indicate that living environments long-term after largescale disasters are associated with dietary habits and nutritional intake among recent mothers.

Abstract
BACKGROUND Trajectories of postpartum depressive symptoms up to 1 year after childbirth and the related risk factors remain unclear. Accordingly, this study aimed to examine the 1-year trajectories of postpartum depressive symptoms and their associated risk factors. METHODS A total of 22,493 pregnant women were recruited between July 2013 and September 2016 in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study in Japan. Among them, 11,668 women with no missing data were included in the analyses. Depressive symptoms were assessed at 1 month and 1 year postpartum using the Edinburgh Postnatal Depression Scale. Multinominal logistic regression analysis was conducted after adjusting for covariates. RESULTS The prevalence of depression was 13.9% at 1 month and 12.9% at 1 year postpartum. We identified four depression trajectories, i.e., "persistent (depressed throughout the 1 year postpartum)" (6.0%), "recovered (depressed at 1 month postpartum and recovered within a year)" (7.9%), "late-onset (became depressed after 1 month postpartum)" (6.8%), and "resilient (not depressed throughout 1 year postpartum)" (79.2%). Psychological distress during pregnancy was significantly associated with all trajectories (persistent: odds ratio [OR]=10.24, 95% confidence interval (CI)=8.40-12.48; recovered: OR=3.78, 95%CI=3.28-4.36; and late-onset: OR=3.96, 95%CI=3.40-4.62). LIMITATIONS Postpartum depression was evaluated only by a self-administered questionnaire and the dropout rate was not neglectable. CONCLUSIONS This study highlighted the high prevalence of depressive symptoms at 1 year postpartum and found that half of the depressive symptoms at 1 year were late-onset. The findings suggest the necessity of long-term follow-up (up to 1 year) for perinatal mental health.

Abstract
Background Anti-programmed cell death protein 1 (PD-1) antibody monotherapy (PD1) has led to favorable responses in advanced non-acral cutaneous melanoma among Caucasian populations; however, recent studies suggest that this therapy has limited efficacy in mucosal melanoma (MCM). Thus, advanced MCM patients are candidates for PD1 plus anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) combination therapy (PD1 + CTLA4). Data on the efficacy of immunotherapy in MCM, however, are limited. We aimed to compare the efficacies of PD1 and PD1 + CTLA4 in Japanese advanced MCM patients. Patients and methods We retrospectively assessed advanced MCM patients treated with PD1 or PD1 + CTLA4 at 24 Japanese institutions. Patient baseline characteristics, clinical responses (RECIST), progression-free survival (PFS), and overall survival (OS) were estimated using Kaplan–Meier analysis, and toxicity was assessed to estimate the efficacy and safety of PD1 and PD1 + CTLA4. Results Altogether, 329 patients with advanced MCM were included in this study. PD1 and PD1 + CTLA4 were used in 263 and 66 patients, respectively. Baseline characteristics were similar between both treatment groups, except for age (median age 71 versus 65 years; P < 0.001). No significant differences were observed between the PD1 and PD1 + CTLA4 groups with respect to objective response rate (26% versus 29%; P = 0.26) or PFS and OS (median PFS 5.9 months versus 6.8 months; P = 0.55, median OS 20.4 months versus 20.1 months; P = 0.55). Cox multivariate survival analysis revealed that PD1 + CTLA4 did not prolong PFS and OS (PFS: hazard ratio 0.83, 95% confidence interval 0.58-1.19, P = 0.30; OS: HR 0.89, 95% confidence interval 0.57-1.38, P = 0.59). The rate of ≥grade 3 immune-related adverse events was higher in the PD1 + CTLA4 group than in the PD1 group (53% versus 17%; P < 0.001). Conclusions First-line PD1 + CTLA4 demonstrated comparable clinical efficacy to PD1 in Japanese MCM patients, but with a higher rate of immune-related adverse events. Anti-PD-1 plus anti-CTLA-4 antibody therapy (PD1 + CTLA4) is an option for patients with advanced mucosal melanoma (MCM). Data on the efficacy of PD1 + CTLA4 compared with PD-1 monotherapy (PD1) for MCM, however, are limited. We retrospectively analyzed data from 329 Japanese patients with advanced MCM treated with PD1 or PD1 + CTLA4. No significant differences in objective response rate, progression-free survival, or overall survival were observed. Immune-related adverse events resulting in treatment cessation were higher in the PD1 + CTLA4 group.

Abstract
BACKGROUND Studies on associations between maternal personality and alcohol use have examined only one time point during pregnancy in Western countries. We aimed to examine the association between maternal personality and alcohol use in early and middle pregnancy in Japan. METHODS We analyzed data from 17,144 pregnant women in Japan who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. Personality was assessed using the short-form Eysenck Personality Questionnaire-Revised. Women were dichotomized as current drinkers or non-drinkers in both early and middle pregnancy. Odds ratios (ORs) and 95% confidence intervals (CIs) for alcohol use in early and middle pregnancy and continued alcohol use between early and middle pregnancy were calculated for 1 standard deviation increase in each personality scale, adjusted for age, as well as education, work status, fertility treatment, and parity. RESULTS Higher extraversion scores were associated with alcohol use in early (OR, 1.16; 95% CI, 1.12-1.20) and middle pregnancy (OR, 1.17; 95% CI, 1.10-1.25). Higher psychoticism scores were associated with continued alcohol use into middle pregnancy (OR, 1.07; 95% CI, 1.01-1.14) and alcohol use in middle pregnancy (OR, 1.07; 95% CI, 1.02-1.13). Neuroticism was not associated with alcohol use in early or middle pregnancy. Lower lie was associated with alcohol use in early (OR, 0.95; 95% CI, 0.91-0.98), but not in middle pregnancy. CONCLUSIONS Different personality scales are associated with alcohol use at different points during pregnancy.

Abstract
Background Although the postpartum period is suggested to provide an ideal opportunity for interventions to prevent hazardous drinking, evidence on the associations of education and income with hazardous drinking during this period is limited, including in Japan. Methods We analyzed data from 11,031 women who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study in Japan. Hazardous drinking was defined as ethanol intake of ≥20 g/day 1 year after delivery. We conducted multiple logistic regression analyses to examine whether educational attainment or equivalent household income was associated with hazardous drinking, adjusting for age, parity, drinking status during pregnancy, work status, postpartum depression, breastfeeding, and income/education. We also conducted stratified analyses by income and education groups. Results The prevalence of hazardous drinking 1 year after delivery was 3.6%. Lower education was associated with hazardous drinking; the odds ratio (95% confidence interval) of high school education or lower compared with university education or higher was 2.17 (1.59–2.98). Lower income was also associated with hazardous drinking, but this association disappeared after further adjustments for education; the odds ratios (95% confidence intervals) of the lowest compared with highest level of income were 1.42 (1.04–1.94) and 1.12 (0.81–1.54), respectively. A significant interaction was detected; lower education and lower income were associated with increased risks of hazardous drinking only in a lower income group and lower education group, respectively. Conclusions Postpartum women with lower education and lower income had higher risks of hazardous drinking in Japan.

Abstract
BACKGROUND Secondhand smoke (SHS) from partners is a major source of exposure for non-smoking women. However, epidemiological studies have rarely examined social factors associated with continued and indoor smoking among pregnant women's partners. METHODS We analyzed data on 6091 partners of non-smoking pregnant women in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study. Partners' age, education, income, workplace SHS exposure (almost never or sometimes, almost every day), and pregnant women's smoking history (never, quit before pregnancy awareness, quit after pregnancy awareness) were used as social factors. Multivariate logistic regression analyses were conducted to examine the associations of social factors with partners' continued smoking and indoor smoking. RESULTS Among 2432 smoking partners, 2237 continued to smoke after pregnancy awareness. Workplace SHS exposure was associated with increased risk of partners' continued smoking: the odds ratio of workplace SHS exposure almost every day compared with almost never or sometimes was 2.08 (95% confidence interval, 1.52-2.83). Women's quitting smoking after-but not before-pregnancy awareness was associated with decreased risk of partners' continued smoking: the odds ratio of women's quitting after pregnancy awareness compared with never smoking was 0.57 (95% confidence interval, 0.40-0.80). About one-third of partners who continued to smoke did so indoors. Older age, lower education, workplace SHS exposure, and women's quitting smoking after pregnancy awareness were associated with increased risk of partners' indoor smoking. CONCLUSIONS Workplace SHS exposure and pregnant women's smoking history were associated with continued smoking and indoor smoking among partners of non-smoking pregnant women.

Abstract
Background The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study was launched in 2013 to evaluate the complex interactions of genetic and environmental factors in multifactorial diseases. The present study describes the maternal baseline profile and perinatal data of participating mothers and infants. Methods Expectant mothers living in Miyagi Prefecture were recruited from obstetric facilities or affiliated centers between 2013 and 2017. Three sets of self-administered questionnaires were collected, and the medical records were reviewed to obtain precise information about each antenatal visit and each delivery. Biospecimens, including blood, urine, umbilical cord blood, and breast milk, were collected for the study biobank. The baseline maternal sociodemographic characteristics, results of screening tests, and obstetric outcomes were analyzed according to the maternal age group. Results A total of 23,406 pregnancies involving 23,730 fetuses resulted in 23,143 live births. Younger maternal participants had a tendency toward a higher incidence of threatened abortion and threatened premature labor, while older age groups exhibited a significantly higher rate of low lying placenta, placenta previa, gestational diabetes, and hypertensive disorders of pregnancy. Conclusions The present study clearly shows the distribution of maternal baseline characteristics and the range of perinatal outcomes according to maternal age group. This cohort study can provide strategic information for creating breakthroughs in the pathophysiology of perinatal, developmental, and noncommunicable diseases by collaborative data visiting or sharing.

Abstract
AIM In the present immunohistochemical study, the expression of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 in the gingival tissues of renal transplant patients treated with cyclosporin A was assessed. Gingival overgrowth (GO) frequently occurs in transplant patients receiving immunosuppressive drugs such as cyclosporine and this gingival inflammation might play an important role in the pathogenesis of drug-induced GO. METHODS Twenty-eight human gingival biopsies were taken from healthy patients with chronic periodontitis (N.=14 control group), and from renal transplant recipients treated with cyclosporin A (N.=14 test group). The retrieved specimens were immunohistochemically processed and stained for vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67. RESULTS The levels of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 were found to be significantly different among groups (P>0.001), with patients treated with cyclosporin A showing higher levels of all the analyzed markers compared to control group. CONCLUSION In summary, the data from this pilot study suggests that the investigated factors have a role in the inflammation processes associated to immunosuppressive therapy. However, further studies with a larger sample population need to be conducted for an exhaustive knowledge of the mechanisms leading to GO.

Abstract
A rear-excitation femtosecond-laser-driven photoelectron gun (PE-gun) is developed for measuring time-resolved cathodoluminescence (TRCL) spectrum of wide bandgap materials and structures such as semiconductors and phosphors. The maximum quantum efficiency of a 20-nm-thick Au photocathode excited using a frequency-tripled Al(2)O(3):Ti laser under a rear-excitation configuration is 3.6×10(-6), which is a reasonable value for a PE-gun. When the distance between the front edge of the PE-gun and the observation point is 10 mm, the narrowest electron-beam (e-beam) diameter is 19 μm, which corresponds to one tenth of the laser-beam diameter and is comparable to the initial e-beam diameter of a typical W hair-pin filament of thermionic electron-gun. From the results of TRCL measurements on the freestanding GaN grown by the ammonothermal method and a GaN homoepitaxial film grown by metalorganic vapor phase epitaxy, overall response time for the present TRCL system is estimated to be 8 ps. The value is the same as that of time-resolved photoluminescence measurement using the same excitation laser pulses, meaning that the time-resolution is simply limited by the streak-camera, not by the PE-gun performance. The result of numerical simulation on the temporal e-beam broadening caused by the space-charge-effect suggests that the present PE-gun can be used as a pulsed e-beam source for spatio-time-resolved cathodoluminescence, when equipped in a scanning electron microscope.

Abstract
We report a rare case with tetralogy of Fallot (TOF) and agenesis of the internal carotid artery (ICA) who presented serious intracerebral haematomas. In the literature, this is the first documented case having these complications simultaneously. Extreme hypoxic insults followed by recovery were detected by O2 saturation monitor before two bleeds. Chronic brain hypoxia could make the vasculature weak, which was shown in the histological examination. A 2-year-old girl was transferred to us with a general convulsion due to intracerebral haematoma. She had been showing general cyanosis from birth due to TOF. Repeated intracerebral haemorrhages ended her life. Histological study showed dilated vascular channels in the subarachnoid space and necrotizing vasculature obstructed by fibrinous thrombi adjacent to the haematoma. Fibrosis of the vessel wall with infiltration of macrophages suggested subacute or chronic lesions rather than acute necrosis due to the multiple haemorrhages. The intracerebral haematomas and agenesis of the ICA were observed as unilateral hemispheric vascular complications of TOF. Chronic brain hypoxia could play an important role in weakening the vessel wall and erythrocytosis caused obstructing thrombi. We speculate these factors generated the intracerebral haematomas.

Abstract
We report a rare case of an epithelial cyst at the right frontal convexity. A 60-year-old woman came to our hospital suffering from dysarthria and gait disturbance. Computed tomography (CT) of the brain on admission showed a round low-density area, 6 cm in diameter, at the right frontal convexity. Midline shift and displacement of the lateral ventricle are seen. There is no contrast enhancement effect. Excision of the cyst wall and fenestration into the subarachnoid space was carried out and the patient was discharged with no neurological deficits. After 5 years, regrowth of the cyst was seen. Cyst-peritoneal shunt was performed and she was discharged uneventfully. Light microscopy showed the cyst wall consisted of a monolayer of flat epithelium and loose connective tissue. An electronmicrograph of the cyst wall showed a non-ciliated epithelial layer with microvilli and basement membrane. The epithelial cells connecting with each other through desmosome have numerous endoplasmic reticulum and mitochondria. Interdigitation of the cytoplasmic membrane was not seen. The term "epithelial cyst" seems ambiguous. We discuss the pathogenesis and the nomenclature for intracranial benign cystic lesions based on the previous literature.

Abstract
Four patients presented with intracranial hemorrhage mainly consisting of acute subdural hematoma (ASDH), who had all undergone aneurysm clipping 2-20 years earlier. Whether the clips had slipped or new trauma had caused the bleeding was difficult to determine, since the initial computed tomography showed that the subarachnoid hemorrhage or the intracerebral hematoma developed near the clips. Angiography in three patients showed that the clips had not slipped off. Three of four ASDHs appeared in the same side as the craniotomy used for the previous aneurysm surgery. Anti-platelet agents and ventriculoperitoneal shunting had been previously used in two patients with no causal signs of trauma. The outcomes were poor in three patients and one patient died. Weakening of the extra- or intracranial structure after aneurysm surgery might have been involved together with the postoperative anti-platelet agent and shunt treatment in the etiology of the present ASDH.
