    Abstract Objective: We evaluated adherence to and 1-year persistence of two third-generation anti-seizure medications (ASMs), lacosamide and perampanel, in adult patients with focal epilepsy, compared with lamotrigine and levetiracetam. Methods: A cohort study was conducted using a Japanese health insurance claims database (JMDC Inc.). We identified patients with adult-onset focal epilepsy who initiated any of the four ASMs between August 31, 2016, and October 31, 2019. Patients were further classified into ASM-naïve patients initiating any of the four ASMs as first-line treatment, and ASM-experienced patients initiating any of the four ASMs as second- or later-line treatment. Outcomes included adherence (proportion of days covered [PDC], defined as the total number of days covered by ASMs divided by the total number of days in the follow-up period) and 1-year persistence for the four ASMs. Results: We identified 141 lacosamide, 75 perampanel, 80 lamotrigine, and 530 levetiracetam initiators. Among these, the proportion of ASM-naïve patients was highest in the levetiracetam group (60.8%), followed by the lamotrigine (25.0%), lacosamide (20.6%), and perampanel groups (1.3%). Mean PDC (standard deviation) was similar across the four groups, at 0.95 (0.08) for lacosamide, 0.93 (0.12) for perampanel, 0.92 (0.10) for lamotrigine and 0.94 (0.11) for levetiracetam. The proportion of patients persisting with treatment for 1 year was highest in the lacosamide group (73.0%), followed by the levetiracetam (58.3%), lamotrigine (57.5%), and perampanel groups (54.7%). In ASM-naïve patients, adherence and 1-year persistence were almost identical in the lacosamide, lamotrigine, and levetiracetam groups. Results for ASM-experienced patients did not significantly differ from those of all patients. Significance: With regard to adherence and 1-year persistence, lacosamide may be equal to or better than lamotrigine and levetiracetam, especially in patients with experienced ASM, while perampanel may be comparable to lamotrigine and ...

    Abstract ObjectivesOrofacial clefts are common birth defects with a lack of strong evidence regarding their association with maternal nutrition. We aimed to determine whether a relationship exists between maternal nutrient or multivitamin intake and orofacial clefts.DesignThis is a prospective, population-based nationwide cohort study.SettingThe study was conducted in 15 regional centres, consisting of local administrative units and study areas.ParticipantsA total of 98 787 eligible mother–child pairs of the Japan Environment and Children’s Study were included.InterventionExposures were maternal nutrition and the use of supplemental multivitamins in mothers.Primary and secondary outcome measuresOutcomes were the occurrence of any orofacial cleft at birth. Multinomial logistic regression analyses were used to evaluate the association between maternal multivitamin intake and the incidence of orofacial clefts.ResultsOf the 98 787 children, 69 (0.07%) were diagnosed with cleft lip alone, 113 (0.11%) were diagnosed with cleft lip and palate, and 52 (0.05%) were diagnosed with cleft palate within 1 month after birth. Regarding the total orofacial cleft outcome, statistically significant point estimates of relative risk ratios (RR) were determined for multivitamin intake before pregnancy (RR=1.71; 95% CI 1.06 to 2.77) and during the first trimester (RR=2.00; 95% CI 1.18 to 3.37), but the association was not significant for multivitamin intake after the first trimester (RR=1.34; 95% CI 0.59 to 3.01). Maternal micronutrient intake via food was not associated with the incidence of orofacial clefts in offspring.ConclusionsIntake of multivitamin supplements shortly before conception or during the first trimester of pregnancy was found to be associated with an increased incidence of orofacial clefts at birth. Pregnant women and those intending to become pregnant should be advised of the potential risks of multivitamin supplementation.

    Abstract Background Cleft lip and palate (cleft L/P) is one of the most common congenital anomalies and its etiology is assumed to be multifactorial. Recent epidemiological data involving a small number of participants suggested an association between perinatal exposure to heavy metals and cleft L/P in affected children. However, this association requires further investigation in a large cohort. Methods This nested case-control study used a dataset of The Japan Environment and Children's Study, which is an ongoing research project to investigate the association between environmental factors and mother-child health. Participants were enrolled between 2011 and 2014. From the records of fetuses/children, we extracted data of isolated cleft L/P cases and matched children without cleft L/P at a ratio of 1:10. The exposures of interest were in utero exposure to four metals (mercury [Hg], lead [Pb], cadmium [Cd], and manganese [Mn]), which were sampled from mothers in the second/third trimester. Conditional logistic regression was used to assess the association between heavy metal exposure and isolated cleft L/P. Three sensitivity analyses were conducted to test the robustness of the findings, including the change in case definition and statistical methods. Results Of 104,062 fetal records involving both live-birth and stillbirth, we identified 192 children with isolated cleft L/P and 1,920 matched controls. Overall, the blood metal levels were low (for example, median Pb level was 5.85, 6.22, and 5.75 μg/L in the total cohort, cases, and controls, respectively). Univariate and multivariate analyses showed that levels of none of the four heavy metals in the mother's blood during pregnancy were associated with the risk of cleft L/P in offspring; the adjusted odds ratios (per 1 μg/L increase) with 95% intervals were 0.96 (0.91-1.03), 1.01 (0.94-1.08), 1.00 (0.61-1.63) and 1.00 (0.97-1.03) for Hg, Pb, Cd and Mn, respectively. The results were consistent in all sensitivity analyses. Conclusions Exposure to these four metals during pregnancy was not associated with isolated cleft L/P at the low exposure level in our cohort.

    Abstract In this study, we assessed the factor structure and construct validity of the parent-reported Inventory of Callous-Unemotional Traits (ICU) among school-aged children and adolescents, aged 6 to 15 years, in a community setting in Japan (n = 10,936). We investigated 15 models that have been reported in previous studies and used confirmatory factor analyses to determine a model that might actually be the best-fit among these. We then examined the correlations between the score of ICU and the Strengths and Difficulties Questionnaire (SDQ) in the best fit model and the three-factor bifactor (3FBF) model with the original ICU through cross-sectional and longitudinal analysis to determine the concurrent and predictive validity of the ICU. The results showed that the best-fit model was the two-factor bifactor (2FBF) model with a revised version of the ICU with 12 items, excluding all but one item of unemotional factors. The cross-sectional and longitudinal analysis showed that higher general callous-unemotional factor scores, callousness and uncaring specific factor scores were significantly associated with a higher level of conduct problems and a lower level of prosocial behaviors in the SDQ. These tendencies were shown both in the 2FBF model with the revised version of the ICU and the 3FBF model with the original ICU. We conclude that the 2FBF model was useful for school-aged community samples, as it predicts increases in conduct problems and decreases in prosocial behavior with fewer items than the 3FBF model.

    Abstract Objective. To assess dose, characteristics, and coprescribed analgesics in patients newly prescribed pregabalin for neuropathic pain and fibromyalgia in Japan. Methods. Based on the medical and prescription information present in the Medical Data Vision database, we analyzed the initial and maximum daily doses, prescription period, coprescribed analgesics, and neuropathic pain-related disorders of patients newly prescribed pregabalin between 01 July 2010 and 31 December 2013. Results. A total of 45,331 patients (mean age 66.8 years, 48.7% men) were newly prescribed pregabalin during this period. The mean initial and maximum daily doses were 97.3 mg and 127.8 mg, respectively, and decreased yearly. The duration of the prescription period was 111.9 (mean) and 53 (median) days, and the frequently coprescribed analgesics included NSAIDs, opioids, and Neurotropin®. About one half of the patients had spinal disorders. Conclusion. In Japan during the period examined, the number of newly prescribed pregabalin users increased, but the initial and maximum daily doses decreased yearly after pregabalin went on the market. The maximum daily dose in Japan was lower than those reported in the USA and Europe. These differences might be associated with patient age and physical status and with anxiety about possible adverse events.

    Abstract Abstract Background Studies using data from Western countries have raised concerns that treating pregnant women with antidepressants may increase the risk of autism spectrum disorders (ASDs) in their offspring. However, to date, the studies are inconclusive. We therefore examined the association between antidepressant use and ASD using claims data collected in Japan. Methods This retrospective cohort study was based on claims data from mothers and their children from January 2005 to July 2014, obtained from the Japan Medical Data Center. The information from mothers and children was linked using the family identification code. Information on antidepressant prescriptions during pregnancy was extracted from the database. To collect information on ASD, children for whom data were available 24 months or more after birth were followed up from birth through July 2014 or up until their withdrawal from the database. To ensure appropriate diagnosis of ASD, mother-child pairs where the children’s data did not cover the 24 months after birth or pairs where children had a diagnosis of ASD within only 23 months after birth were excluded from the study cohort. We used logistic regression analyses to evaluate the association between antidepressant use during pregnancy and the children’s ASD diagnosis. All statistical analyses were performed using IBM SPSS (Statistical Package for the Social Sciences) Statistics ver. 21.0. Results Of the 53,864 eligible mother-child pairs, 26,925 met the study criteria. Crude analysis showed that the ASD prevalence in children was significantly higher with any antidepressant use than with non-use (odds ratio [OR], 2.32; 95% confidence interval [CI], 1.08, 4.95). However, when the analysis was adjusted for the confounding effect of maternal depression during pregnancy, statistical significance was lost (OR, 0.76; CI, 0.27, 2.18). Conclusions After adjustment for confounders, we found no significant association between antidepressant use during pregnancy and ASD in children in Japan. This result ...

    Abstract A number of preclinical and clinical studies have suggested that omega-3 fatty acids have a prophylactic effect against depression. The aim of this study was to explore the effect of eicosapentaenoic acid (EPA) on development of depression among Japanese patients with hyperlipidemia. This was a 3-year follow up study based on medical claims data obtained from Japan Medical Data Center. A total of 76,561 patients were eligible for the final analyses. The exposure group included EPA drug users categorized into 2 groups based on adherence to EPA using the Medication Possession Ratio (MPR) with a cutoff of 80%. The control group (non-EPA group) consisted of subjects taking lipid-lowering medications other than EPA. A Cox proportional hazard model was used to evaluate the association between EPA drug use and the development of depression. Over 3 year-follow up, 1319 (1.7%) patients developed depression. In the multivariate Cox proportional hazard model, no association was found between depression and EPA drug use in the MPR ≥80% group (HR:0.89, 95%CI: 0.67 to 1.20) or MPR < 80% group (HR:1.00, 95%CI: 0.73 to 1.37) compared with the non-EPA group. No convincing evidence was found to support the association between EPA and risk of depression before and after adjusting for age, gender, and comorbidity.

    Abstract The Autism Spectrum Screening Questionnaire (ASSQ) is equipped with good properties for screening the broader phenotype of autistic traits, but it is standardized for a limited age range-from 7 to 16 years. To contribute to the early detection of Autism Spectrum Disorder (ASD), particularly in high functioning children with ASD, likely to cause maladjustments during school age, the present study examined psychometric properties to apply the ASSQ to a younger age. We tested parents' ASSQ ratings for preschool children in clinical (N = 154, average age 60.77 months, range 55-72 months) and community settings (N = 1390, average age 60.53 months, range 57-68 months) in Japan. The results showed, just as in school-aged children, the ASSQ had reliability and validity as a screening instrument for preschool children in community settings. A cut-off of 7 with sensitivity of 0.93 and specificity of 0.84 is recommended for community screening. Still, based on the current study with a clinical group, an optimal cut-off score with high sensitivity and high specificity for parents' ASSQ ratings could not be established. The clinicians should be reminded that the ASSQ is a screening instrument, not a diagnosing instrument. Also, this result suggest multi-faceted evaluation is necessary in clinical settings, for example, the addition of teachers' ratings.
