Genotoxic and genoprotective effects of some antipsychotic drugs, methylphenidate and atomoxetine on human lymphocytes and HepG2 cells.

OBJECTIVE: Aripiprazole, risperidone, atomoxetine, and methylphenidate are drugs commonly prescribed for many psychiatric conditions and can be used alone or in combination in children and adolescents. This study aimed to investigate comparatively the possible genotoxic effects or genoprotective potentials of these drugs on human lymphocytes and HepG2 cells. MATERIALS AND METHODS: Cytotoxicity analysis was performed with the cell viability test on human lymphocytes and HepG2 cells, and half-maximal inhibitory concentration (IC50) values of the drugs were determined, and three different doses (» IC50, ½ IC50, and IC50) were applied for genetic analysis. For the determined doses, cells with and without DNA damage were examined by comet analysis. RESULTS: In lymphocytes, aripiprazole and risperidone increased DNA damage at moderate and maximum doses, whereas atomoxetine increased DNA damage only at the maximum dose. In HepG2 cells, risperidone reduced DNA damage at all doses, while atomoxetine increased DNA damage at all doses. On the other hand, in the DNA-damaged cells induced by hydrogen peroxide (H2O2), DNA damage decreased at all concentrations of all drugs in both lymphocytes and HepG2 cells. CONCLUSIONS: As a result, the genotoxicity of the drugs was found to be dose-dependent, and all drugs showed a genoprotective effect on DNA-damaged cells.

The effect of physical activity on mother-child relationship and parental attitudes: a follow-up study examining the long-term effects of COVID-19.

OBJECTIVE: This study was planned to evaluate effects of game-based physical activity model on mother-child relationship and parental attitudes during the prolonged COVID-19 pandemic period. SUBJECTS AND METHODS: This study was designed using a web-based quasi-experimental model with a pre-test/post-test evaluation, with a control group. The mothers who accepted to participate in the study and their children were divided into experimental (group I, n=28) and control groups (group II, n=31). The mothers and children in the experimental group were asked to apply web-based game-based physical activity model for 20 minutes/day for 4 weeks. The online questionnaire included socio-demographic data form, Child Parent Relationship Scale (CPRS), and Parental Attitude Scale (PAS). RESULTS: There were no significant differences between mean scores of pre-test and post-test subscales of the PAS in group I (p>0.05 for all subscales). It was found that post-test scores of democratic subscales of PAS statistically significant decreased (p=0.047) and the authoritarian attitude subscale scores significantly increased (p=0.033) in group II. The mean pre- and post-activity scores of positive/close relationship and conflictual relationship subscales of CPRS differ between groups (p<0.05 for both subscales). Pre-post test scores of group II were found to be significantly lower compared to group II. CONCLUSIONS: Our study provides a moderate improvement in parameters evaluated; however, we suggest that longer-term activities may have a more permanent and statistically significant effect.

Quality of life, emotion dysregulation, attention deficit and psychiatric comorbidity in children and adolescents with vitiligo.

BACKGROUND: Vitiligo is an acquired pigmentation disorder, which can have a negative effect on patient quality of life (QoL). AIM: To evaluate QoL and psychiatric comorbidity in paediatric patients with vitiligo. METHODS: In total, 30 patients aged 8-18 years who were diagnosed with vitiligo and 30 age- and sex-matched healthy controls (HCs) were included in the study. The Children's Depression Inventory, Screen for Child Anxiety Related Disorders, State-Trait Anxiety Inventory for Children and Child Somatization Inventory were completed for both patients and controls. The Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL) was administered to all patients by a child psychiatrist. Families were also asked to complete the Pediatric Quality of Life Inventory and Emotion Regulation Checklist for children. RESULTS: The K-SADS-PL evaluation showed that 90% of the patients in the vitiligo group had at least one psychiatric diagnosis, whereas this rate was 20% in the HCs (P < 0.001). There were statistically significant differences between vitiligo and HCs in terms of anxiety, state and trait anxiety scores (P < 0.05). Attention deficit and hyperactivity disorder (ADHD) was detected in 36.6% of the patients. CONCLUSION: The most important finding of this study is that anxiety disorders are more prominent than depression in childhood vitiligo. Another important finding of this study is that the prevalence of ADHD is significantly higher than the normal population.
