Our study aimed to assess efficacy and tolerability of extended-release lithium sulfate (ERLS) in youths with BD. <b><i>Methods:</i></b> A longitudinal perspective intervention study was thus conducted on a single cohort of 36 patients with BD aged 12-17 years treated with ERLS and followed up for 1 year. ERLS was titrated up to reach optimal plasma concentrations during the 3 months before baseline visit (T0). Then, patients underwent five follow-up visits after 1, 2, 3, 5, and 11 months and were administered with a battery of self- and parent-rated questionnaires and interviews to evaluate, at each timepoint, ERLS-related side effects, manic and depressive symptoms, emotional dysregulation (ED), NSSI and suicidality, and aggressiveness. Regular clinical assessments were also conducted, as well as blood tests, urinalysis, and EKG.

This article reviews the current understanding and impact of pain in TS as well as identifies possible areas for emphasis for future research on pain in TS. <b><i>Methods:</i></b> Using a comprehensive search strategy in two relevant research databases (PubMed and Scopus), we searched for relevant peer-reviewed, primary research articles, and review articles. Search terms used were Tourette syndrome, tic disorder, pain, pain management, sensory, and sensory gating. <b><i>Results:</i></b> A total of 116 pertinent articles were identified. Pain is reported by 47%-60% of individuals with TS and may relate to different aspects of tic phenomenology or other causes. Pain is more prevalent among TS patients than in the general population and negatively impacts quality of life. To standardize future research efforts, we propose the following classification: tic-related immediate pain, tic-related delayed injury/pain, suppression-related pain, premonitory urge-related pain, and associated primary pain syndromes. Altered sensory gating and interoceptive processing abnormalities are possible mechanisms contributing to pain in TS but warrant further study. Despite pain prevalence, most TS clinical rating scales and outcome measures used in therapeutic studies do not incorporate sufficient information regarding pain.

Several disease-modifying treatments are in early trials for SCN2A-RDs, and as such, clinical outcome assessments (COAs) are necessary. The Vineland-3 introduced growth scale values (GSVs), which are useful for measuring within-person change and thus may be useful in future clinical trials. The purpose of this study was to evaluate the psychometric properties of the Vineland-3 GSVs in SCN2A-RDs in preparation for future clinical trials. <b><i>Methods:</i></b> A sample of 65 individuals with SCN2A-RDs (mean = 108, SD = 76.0 months) was recruited for a clinical trial readiness study. The Vineland-3 Comprehensive Interview was administered by trained raters at regular intervals. Multiple psychometric properties were evaluated, including floor and ceiling effects, split-half internal consistency, test-retest reliability, and inter-rater reliability (on approximately 20% of all completions). <b><i>Results:</i></b> Floor effects were relatively infrequent on the GSV metric but occurred on all subdomains using the norm-referenced v-scale metric.

Inter-rater reliability was also very strong, though it was more variable (α<sub>kripp</sub> range 0.78-1.00). <b><i>Conclusion:</i></b> The Vineland-3 holds great potential as a COA in SCN2A-RDs; it exhibited very strong psychometric properties in this sample. This is a prerequisite level of evidence needed to demonstrate that a measure is fit-for-purpose for future clinical trials. While some reliability was high, some domains (e.g., domestic) still exhibited problems related to floor effects, which may suggest that they are less relevant to this population.

New bupropion use was defined as at least 1 year without any prior bupropion dispensed prescription. Potential indications for bupropion treatment were identified from inpatient/outpatient records (ICD-10-CM diagnoses) in the 30 days prior to bupropion initiation. All analyses were stratified by age: children (6-17 years), young adults (18-29 years), and adults (30-64 years) and treatment duration up to 1 year was estimated with Kaplan-Meier estimation. <b><i>Results:</i></b> The study sample included 39,833 children, 177,710 young adults, and 548,557 adults newly initiating bupropion treatment.

Accumulating data suggest that genetic factors may contribute to clinically relevant pharmacodynamic (e.g., dopamine transporter-<i>SLC6A3</i> also commonly known as <i>DAT1</i>) or pharmacokinetic (e.g., the drug metabolizing enzyme Cytochrome P450 2D6 <i>CYP2D6</i>) effects of methylphenidate (stimulant) and atomoxetine (non-stimulant), which are commonly prescribed medications.
