ABSTRACT

BACKGROUND: Suicide in the young population has been an urgent issue worldwide. The study aimed to assess the overall prevalence of suicide ideation and the associations between adolescent suicide and psychiatric distress/ psychiatric morbidity, as well as the myths and help-seeking behavior of adolescents with suicide ideation. METHOD: The nationwide community-based telephone interviews were conducted with adolescents aged between 15 to 19 for five consecutive years (2015-2019). The measurements included demographic variables, the five-item Brief Symptom Rating Scale (BSRS-5), and help-seeking experiences of formal medical services or psychological consultations. Stepwise multiple regression analysis was performed to examine which of the five symptoms and demographic variables had discriminative validity for suicidal ideation. RESULTS: Among 727 participants, the prevalence of lifetime and one-week suicidal ideation was 11.4% and 2.8%, respectively. Adolescents with lifetime/ one-week suicidal ideation and with psychiatric morbidity (BSRS-5≥6) sought psychiatric service more than their counterparts (p<0.001). Female, depression, hostility, and anxiety were significantly associated with suicidal ideation in adolescents. LIMITATIONS: Telephone interview and structured questionnaire. CONCLUSION: Adolescents with psychiatric morbidity who have sought help should be carefully monitored for suicidal ideation by parents, teachers, mental health workers, and psychiatric specialists altogether.

ABSTRACT

OBJECTIVES: The purpose of this study was to identify the optimal dose of osmotic release oral system methylphenidate (OROS-MPH) using a dosage forced-titration scheme to achieve symptomatic remission in children with attention- deficit/hyperactivity disorder (ADHD). We also evaluated the efficacy and safety of, and patient and parent satisfaction with, the change in therapy from immediate-release methylphenidate (IR-MPH) to OROS-MPH over 10 weeks. METHOD: We recruited 521 children and adolescents aged 6-18 years with an American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) diagnosis of ADHD, who had received IR-MPH treatments (<70 mg/day) for at least 1 month. The treatment, switched from IR-MPH to OROS-MPH according to a conversion scheme, started with a 6-week forced-titration phase of OROS-MPH to achieve symptomatic remission (defined as a score of 0 or 1 for each of the first 18 ADHD items in the Chinese version of the Swanson, Nolan, and Pelham, Version IV [SNAP-IV]), followed by a 4-week maintenance phase. The global ADHD severity and drug side effects of the participants were evaluated. Parents completed the ratings scales for the ADHD-related symptoms. Patient and parent satisfaction for the OROS-MPH treatment was also assessed. RESULTS: Among the 439 participants with ADHD who completed the trial, 290 participants (66.1%) achieved symptomatic remission. The mean dose of OROS-MPH among participants in remission was 36.7 mg (1.08 mg/kg) per day. Increased efficacy, superior satisfaction, and safety equivalent to that of IR-MPH were demonstrated in intra-individual comparisons from the baseline to the end of study. Determinants for remission included less severe ADHD symptoms (SNAP-IV score < 40), no family history of ADHD, and an appropriate dosage of medication according to the patient's weight. CONCLUSIONS: The findings suggest remission as a treatment goal for ADHD therapy by providing an optimal dosage of medication for children and adolescents with ADHD through using an effective and tolerable forced-titration scheme.

ABSTRACT

AIM: To determine the differences in the remission rate, recovery rate, functional improvement, and treatment adherence related to treatment with short-acting immediate-release methylphenidate (IR-MPH) and long-acting osmotic-release oral system-methylphenidate (OROS-MPH) in a naturalistic setting among Taiwanese children with attention-deficit-hyperactivity disorder (ADHD). METHODS: A total of 757 children with ADHD, aged 6-18 years, was evaluated using the following in order determine functional improvement and treatment adherence: the Chinese version of the Swanson, Nolan, and Pelham, version IV scale (SNAP-IV-C), Clinical Global Impression-ADHD-Severity (CGI-S) to measure remission and recovery rates, the Chinese version of the Social Adjustment Inventory for Children and Adolescents (CSAICA), and caregiver's satisfaction rate, treatment adherence, and frequency of adverse effects. RESULTS: According to the SNAP-IV-C scores, the remission rate was 30.72%, and the recovery rate was 16.38%. Compared to short-acting IR-MPH, OROS-MPH was associated with greater functional improvement and treatment adherence among children with ADHD. CONCLUSION: OROS-MPH treatment at the adequate dosage can achieve higher remission and recovery rates, produce greater functional improvement, and result in better treatment adherence than IR-MPH treatment.

ABSTRACT

Rett syndrome (RTT) is a severe X-linked postnatal neurodevelopmental disorder. The syndrome is caused primarily by mutations in the methyl CpG binding protein 2 (MeCP2) gene on Xq28. Most individuals with RTT are female, and female RTT is normally heterozygous for mutations in MeCP2. Patients with RTT display a normal period of development prior to the onset of symptoms, at which point they undergo a period of regression. Currently, no effective medication is available for this disorder, although animal studies have suggested that RTT symptoms are potentially reversible. For females with RTT, the severity of symptoms and progression of the disease varies a great deal, despite its homogenous genetic origin. These differences could be attributed to differences in the mutation points of MeCP2 and the skew caused by X-chromosome inactivation. Thus, the increased expression in the normal MeCP2 gene could decrease the severity of the disease. Based on findings from studies on animals indicating that fluoxetine (an antidepressant) and cocaine (a psychostimulant) can increase MeCP2 expression in the brain, it is suggested that early intervention with antidepressants or psychostimulants could increase the normal MeCP2 expression in females with RTT, who are normally heterozygous. This therapeutic hypothesis could be tested in an RTT animal model. Following the identification of the antidepressants or psychostimulants with the greatest influence on MeCP2 expression, a combination of early detection of the disorder with early intervention may result in improved therapeutic outcomes. Furthermore, a trial investigating the effects of antidepressants or psychostimulants on MeCP2 expression in lymphocyte culture from patients with RTT is suggested for clinical therapeutic prediction.
