Periconceptional folic acid intake and disturbing factors: A single-center study in Japan.

We investigated folic acid (FA) intake and disturbing factors in pregnant women who visited our center in 2017. Among 1531 pregnant women, 45.1% of women initiated FA supplementation before pregnancy. The risk of failure of supplementation was significantly lower among women of ≥35 (adjusted odds ratio [aOR] 0.43) and 30-34 years of age (aOR: 0.59) in comparison to women of <30 years of age, and among those conceived with timing/artificial insemination of husband (aOR 0.47) and in vitro fertilization/intracytoplasmic sperm injection (aOR 0.32) in comparison to those conceived naturally. The risk among those with 1 (aOR 1.44) or ≥2 previous deliveries (aOR 2.75) was significantly higher in comparison to nulliparous women. Young, multiparous women, and those with natural conception should be targeted to promote preconceptional FA intake.

The Japanese experience and pharmacokinetics of antenatal maternal high-dose immunoglobulin treatment as a prophylaxis for neonatal hemochromatosis in siblings.

Background: Neonatal hemochromatosis (NH) is a rare but serious disease causing fulminant hepatic failure. The recurrence rate of NH in a subsequent infant of a mother with an affected infant is 70-90%. Recently, antenatal maternal high-dose intravenous immunoglobulin (IVIG) treatment has been reported to be effective for preventing NH recurrence. However, data on the IgG concentrations during this treatment are limited.Objective: We report a Japanese experience and present a pharmacokinetic simulation model of IgG during IVIG treatment.Methods: Women with histories of pregnancy diagnosed with NH were treated with IVIG weekly from the second trimester until the end of gestation. Serum IgG levels during treatment were collected frequently and pharmacokinetics were simulated by a two-compartment model.Results: Six women were included during eight pregnancies. None experienced severe adverse events. Three out of eight infants showed temporary liver dysfunction, but none required any treatment. A simulation study showed that the estimated trough and peak levels of IgG concentrations during IVIG were 2000-3000 and 4000-5000 mg/dl, respectively.Conclusion: This treatment prevented the recurrence of NH in siblings in Japanese women. We examined the details of serum IgG concentrations and introduced a new pharmacokinetic simulation model of IgG concentrations during IVIG treatment.

Effects of group musical therapy on inpatients with chronic psychoses: a controlled study.

The objective of the present study was to examine the efficacy of group musical therapy for inpatients with DSM-IV schizophrenia or schizoaffective psychosis. Thirty-four therapy group subjects in a ward for long-stay female patients received 15 group musical therapy sessions over 4 months, while 32 waiting group subjects from another ward with the same function were to wait for the sessions until the studied course was completed. The assessment included measures of psychotic symptoms, objective quality of life and subjective musical experiences. Comparison of the groups indicated that significant advantages in the therapy group subjects were detected in some measures concerning personal relations and a subjective sense of participation in a chorus activity. However, the follow-up evaluation suggested that the improvement might not be durable. These findings suggested that the musical therapy had some, but possibly only short-lived, effects on personal relations and musical experiences of chronic psychotic patients.
