Mismatch negativity (MMN) is a component of auditory event-related potentials that reflects automatic change detection in the brain, showing qualities of endophenotypes in schizophrenia. MMN deficiency is one of the robust findings in patients, and it reflects both cognitive and functional decline. Catechol-o-methyltransferase (COMT) is a key enzyme involved in regulating dopamine transmission within the prefrontal cortex.

Medical students often become involved as post-disaster emergency responders despite incomplete training, and in doing so may suppress their immediate experiences as victims and survivors. This experience, however, may lead them to increase their motivation to help others. We examined how cognitive and emotional reactions to disaster correlated with posttraumatic growth (PTG) in medical students in Fukushima, Japan after the Great East Japan Earthquake of March 11, 2011.

Sinusoidal obstruction syndrome (SOS) is a lethal complication after hematopoietic stem cell transplantation (HSCT). Defibrotide (DF) is the only drug internationally recommended for SOS treatment in Western countries. Recombinant human soluble thrombomodulin (rhTM), which is promising for the treatment of patients with disseminated intravascular coagulation, is also reported to be potentially effective for SOS.

Article Synopsis
  • A study analyzed outcomes of 713 patients who developed subsequent solid cancers after hematopoietic cell transplantation (HCT), revealing they were diagnosed at a median age of 55, which is significantly younger than the general population's average age of 67 for primary cancers.
  • The survival rate three years post-diagnosis of subsequent solid cancers was 60%, with the overall risk of mortality higher among HCT patients, as these cancers accounted for 76% of deaths in the study cohort.
  • Findings highlight the necessity for earlier cancer screening in HCT patients, as they generally face worse survival outcomes compared to the general population for certain cancers, while the biological and genetic factors are still unclear.*

After the Fukushima nuclear power plant accident, numerous evacuees reported poor mental health status and high-risk perceptions of the health effects of radiation. However, the temporal associations between these variables have not yet been examined. Using data from the Fukushima Health Survey, we examined changes in risk perception of the health effects of radiation over time and assessed the effects of mental health on such changes using logistic regression analysis.

Epigenetic modification including DNA methylation may affect pathophysiology and the response to antipsychotic drugs in patients with schizophrenia. The objective of the present study was to investigate the effect of the DNA methylation of ANKK1 (ankyrin repeat and kinase domain containing 1) on the response to aripiprazole and plasma levels of monoamine metabolites in antipsychotic-free acute schizophrenia patients. The subjects were 34 Japanese patients with schizophrenia who had been treated with aripiprazole for 6 weeks.

Article Synopsis
  • AK2 is a key enzyme in mitochondria, and mutations in this enzyme lead to a severe condition called reticular dysgenesis, which affects the immune system and neutrophil development.
  • Research using stem cells from RD patients showed that hematopoietic differentiation was significantly impaired, indicating problems at the very early stages of cell development.
  • The study found that AK2 is crucial for providing energy (ATP) to the nucleus during the differentiation process, which influences the genetic activity needed for the proper development of blood stem cells.

Article Synopsis
  • The study investigated the relationship between radiation exposure, psychological trauma from the Fukushima nuclear accident, and current levels of anxiety and psychological distress among residents who did not evacuate after the disaster.
  • A survey was conducted with 1,684 residents from 49 municipalities, exploring their immediate fears post-accident, current radiation anxiety, and psychological distress levels over five years after the incident.
  • Results indicated that current environmental radiation levels were more impactful on radiation anxiety than levels immediately after the disaster, while various personal and disaster-related factors influenced this anxiety, which in turn affected overall psychological distress.

Using near-infrared spectroscopy, we examined changes in the concentration of oxygenated hemoglobin ([oxy-Hb]) in the frontal lobe during a verbal fluency task in 20 patients with schizophrenia (10 patients each receiving olanzapine [OLZ] and risperidone [RIS]) and 10 healthy controls. We found that [oxy-Hb] levels in the prefrontal region were higher in the patients receiving OLZ than in those receiving RIS. These results suggest that antipsychotic drugs have different effects on cerebral hemodynamic patterns, which may reflect frontal lobe function.
