Although oxytocin may provide a novel therapeutics for the core features of autism spectrum disorder (ASD), previous results regarding the efficacy of repeated or higher dose oxytocin are controversial, and the underlying mechanisms remain unclear. The current study is aimed to clarify whether repeated oxytocin alter plasma cytokine levels in relation to clinical changes of autism social core feature. Here we analyzed cytokine concentrations using comprehensive proteomics of plasmas of 207 adult males with high-functioning ASD collected from two independent multi-center large-scale randomized controlled trials (RCTs): Testing effects of 4-week intranasal administrations of TTA-121 (A novel oxytocin spray with enhanced bioavailability: 3U, 6U, 10U, or 20U/day) and placebo in the crossover discovery RCT; 48U/day Syntocinon or placebo in the parallel-group verification RCT.

Although intranasal oxytocin is expected to be a novel therapy for the core symptoms of autism spectrum disorder, which has currently no approved medication, the efficacy of repeated administrations was inconsistent, suggesting that the optimal dose for a single administration of oxytocin is not optimal for repeated administration. The current double-blind, placebo-controlled, multicentre, crossover trial (ClinicalTrials.gov Identifier: NCT03466671) was aimed to test the effect of TTA-121, a new formulation of intranasal oxytocin spray with an enhanced bioavailability (3.

Background: In communities affected by a disaster, walking can be a feasible form of physical exercise to improve physical and mental health conditions. However, there is limited evidence to support relationships between walking habits and mental health conditions in post-disaster settings. Cross-sectional epidemiological data obtained from a questionnaire survey (conducted in October 2017) of a community affected by the 2011 Great East Japan Earthquake (GEJE) was analyzed to evaluate the relationships.

Background: Few studies exploring the actual practices implemented for long-term mental health and psychosocial support after a natural disaster have been published. This study aimed to reveal (1) the types of activities that were actually provided as mental health and psychosocial support (MHPSS) in the long-term phase after the Great East Japan Earthquake (GEJE) and (2) the problems that must be addressed to provide post-disaster MHPSS activities.

Methods: An open-ended questionnaire was sent to organizations in the Iwate, Miyagi and Fukushima prefectures that were potentially involved in providing MHPSS to communities affected by the GEJE.

Aims: Post-traumatic growth (PTG) refers to positive changes that result from coping with a major life crisis or a traumatic event. Factors influencing PTG in youth have not been well characterized but could have a great impact on overall maturation.

Methods: Fourth to ninth graders (n = 3337) attending elementary or junior high schools located in a district severely damaged by the Great East Japan Earthquake completed a questionnaire, including the revised Posttraumatic Growth Inventory for Children (PTGI-C-R) along with the Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), 31 months after the event.

The purpose of this study was to investigate factors associated with the psychological impact of the Great East Japan Earthquake on high school students 1 year and 4 months after the disaster, and clarify support needs of the students. In the outreach program for students of three high schools in coastal areas of southern Miyagi Prefecture, Japan, 1,973 students were surveyed after obtaining informed consent for participation. Questionnaires included: the Quick Inventory of Depressive Symptomatology (QIDS-J), Self-rating Anxiety Scale (SAS), Impact of Event Scale-revised (IES-R), and Connor-Davidson Resilience Scale (CD-RISC10).

Purpose: Few studies have assessed physical and psychological status in long-term survivors of childhood solid tumors in Japan. For children with such diseases diagnosed and treated in our hospital, our purpose was to clarify the physical and psychological status of long-term survivors and their parents.

Methods: Subjects were 56 patients who were diagnosed at our institution as having a childhood malignant solid tumor between 1982 and 2005 and had been alive for at least 5 years after treatment.

We report a case in which a healthy 18-year-old girl acted as a liver donor for her mother, who had a terminal hepatic illness with a one-year survival probability of 2% without liver transplantation. The daughter, who was the only relative to have a blood type compatible with her mother, offered to donate after the surgeons explained the situation. Our ethical committee required a psychiatrist to evaluate her psychiatric status and competence, and address ethical concerns.
