Clinical pathology, including hematology and serum chemistry, is an important indicator ofbiological changes. Animals for inhalation studies are kept in specific chambers and requirehistorical data for accuracy. Age-related characteristics are essential for interpreting experimental results. This study aimed to provide historical clinical pathology data and analyze age-related trends in these parameters. We collected hematological and biochemical parameters from control groups of male and female F344 rats in the 4-, 13-, 26-, and 52-week repeated inhalation toxicity tests. The number of F344 rats from collected control groups were 24, 60, 50, and 25 males and 25, 60, 50, and 25 females in the 4-, 13-, 26-, and 52-week studies, respectively. Mean comparison, correlation analysis and simple linear regression analysis was conducted to reveal age-related trends. Neutrophil count, eosinophil count, neutrophil percentage, monocyte percentage, total protein, albumin, triglyceride, total cholesterol (TCHO) showed increasing trends, whereas lymphocyte count, lymphocyte percent, platelet count, alkaline phosphatase, albumin/globulin ratio, and inorganic phosphate showed decreasing trends in both the mean comparison and regression analyses. TCHO was con-sidered the most affected parameter by aging in both sexes based on statistical results. Inthis study, we presented clinicopathological data from F344 rats for inhalation toxicity studies.We confirmed aging trends in clinicopathological parameters and identified TCHO as theparameter most affected by aging in F344 rats. These results would be helpful for inhalationresearch using F344 rats.

Objective: The Children in Disaster: Evaluation and Recovery (CIDER) program in Korea was developed to treat children and adolescents exposed to trauma. This study aimed to demonstrate the effectiveness of the CIDER through a comparison with controls. Methods: A total of 85 participants consisted of the intervention group (n=41) and control group (n=44). We assessed the changes in trauma-related symptoms, depression, anxiety, and improvements in quality of life before and after the intervention. Results: In total, bullying and school violence (44.7%) were the most common trauma, followed by sexual abuse (17.6%). Acute stress disorder and post-traumatic stress disorder (PTSD) accounted for 41.2%, and attention-deficit/hyperactivity disorder (ADHD) and developmental disorder were the most common comorbidities (51.8%). The symptoms of trauma, depression, anxiety, and quality of life improved significantly in the intervention group, while the control group did not show significant changes. Conclusion Compared with the control group, the CIDER improved symptoms and quality of life in children and adolescents who had experienced trauma. The CIDER program was practical and easy to apply, even for different ages, types of traumas, and comorbidities.

Objective: We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders. Methods: A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type. The most preferred value in each category in the total population was identified, and differences in the preference ratio of each item among the disease groups were compared. Results: A total of 707 participants were surveyed. In the total population, patients reported high efficacy (44.01%±21.44%) as the main wish for medication, themselves (37.39%±22.57%) and a doctor (35.27%±22.88%) as the main decision makers, and tablet/capsule (36.16%±30.69%) as the preferred type of drug. In the depressive disorders group, the preference ratio of high efficacy was significantly lower, and the preference ratio of a small amount was significantly higher than that of the psychotic disorder and bipolar disorder groups. The preference ratio of a doctor as an important decision maker in the bipolar disorder group was higher compared to the other groups. Conclusion This study revealed the preference for medications and showed differences among patients with psychiatric disorders. Providing personalized medicine that considers a patient’s preference for the drug may contribute to the improvement of drug compliance and outcomes.
