Proof of Concept Study of an Oral Orthotic in Reducing Tic Severity in Tourette Syndrome.

The use of an oral orthotic, called an occlusal splint, has gained recognition for the potential to reduce the frequency of tics for individuals with Persistent Tic Disorders. The purpose of this study was to assess the feasibility of a fully blinded, randomized controlled trial (RCT) to assess the safety, tolerability and initial efficacy of the oral orthotic in youth with chronic tics. Thirteen youth were randomly assigned to wear an active or sham orthotic in a two week double-blind RCT, with a 4-6 week unblinded follow up period. A statistically significant difference was found for change in tic severity between participants wearing the active and sham orthotic. However, this difference was not replicated during the follow up period. The oral orthotic is a promising intervention for the reduction of tics in youth with Tourette's Syndrome and is worthy of continued study to establish intervention efficacy and mechanism of action.

Suicidality Among Psychiatrically Hospitalized Lesbian, Gay, Bisexual, Transgender, Queer, and/or Questioning Youth: Risk and Protective Factors.

Purpose: The study purpose was to compare suicide risk between lesbian, gay, bisexual, transgender, queer, and/or questioning (LGBTQ) and non-LGBTQ adolescents in a psychiatric hospital. Methods: Data were obtained from self-report measures completed by patients 12-17 years of age (n = 334) in a Midwestern psychiatric hospital from 2016 to 2017. Factors analyzed included sexual orientation, gender identity, suicidality, depression, nonsuicidal self-injury, abuse, substance use, bullying, perceived discrimination, and adult support. Results: Nearly one-third of patients identified as LGBTQ. A lifetime suicide attempt was reported by 69.6% of LGBTQ patients compared with 43.6% of non-LGBTQ patients. However, the prevalence of suicide attempts among LGBTQ patients with high adult support did not differ from that of non-LGBTQ patients. In the full logistic regression model adjusting for 13 factors, the adjusted odds ratio of a suicide attempt was 5.25 among transgender/questioning patients and 2.41 among nontransgender lesbian, gay, bisexual, queer, or questioning patients. All risk factors, apart from substance use, were more prevalent among LGBTQ than non-LGBTQ patients (p < 0.005). Among LGBTQ patients of color (Black/Latinx/Other), 91.3% had a lifetime suicide attempt versus 62.3% of White LGBTQ patients (p = 0.009). Conclusion: LGBTQ patients overall, and LGBTQ patients of color in particular, had higher rates of suicide attempts than non-LGBTQ patients. LGBTQ patients also had a higher prevalence of risk factors for suicide; however, the study variables did not fully explain the higher prevalence of suicide attempts. Future research should further examine possible risk factors for suicide among LGBTQ youth, such as stigma and discrimination.

Treatment of separation, generalized, and social anxiety disorders in youths.

Separation, generalized, and social anxiety disorders are common and impairing for children and adolescents. Childhood-onset anxiety disorders frequently persist into adulthood and place youths at risk for future psychiatric disorders, including mood and substance use disorders. Comorbidity is common in childhood anxiety disorders, and studies increasingly take this into account when assessing potential treatments. Existing studies support a number of pharmacological and psychotherapeutic treatments for childhood anxiety disorders. The strongest evidence supports use of selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT). Combination treatment with SSRIs and CBT has been found to be more effective than either treatment alone. Early detection and treatment of childhood anxiety disorders can prevent substantial impairment over the course of a child's development and accumulation of functional disability. Early treatment also may prevent later development of adult psychiatric illness. The authors review the treatment literature and present the case of an adolescent who is brought in for evaluation after years of untreated anxiety.

Type 1 diabetes-related autoantibodies are rare in Alaska native populations.

OBJECTIVES: When clinical data were initially gathered from the Alaskan Eskimos in the 1950's, diabetes mellitus was noted to be quite rare. The prevalence of diabetes has increased significantly since that time, with rates of 10% reported recently in some Alaska native populations. Our goal was to understand the pathogenesis of diabetes among these groups, with the hypothesis that Alaskan Eskimos were predominantly affected by type 2 diabetes, not by latent autoimmune diabetes in adults (LADA). STUDY DESIGN: Population based case control study METHODS: We tested sera from subjects in two Eskimo villages for the presence of type 1 diabetes-related autoantibodies against glutamic acid decarboxylase (GAD65Ab) and tyrosine phosphatase-like islet antigen-2 (IA-2Ab). RESULTS: Among subjects from one Inupiat village (#1) and one SiberianYup'ik village (#2), there were 21 subjects with diabetes mellitus (DM), 17 with impaired glucose tolerance (IGT), and 226 healthy controls with normal glucose tolerance (NGT). In village 1, GAD65 antibodies were not present in either diabetic subjects or those with IGT. One of the healthy controls (1%; 1/97) was positive for GAD65Ab. Similarly, no subjects from this village with DM or IGT had positive IA-2Ab titers, and one healthy control (1%; 1/97) was positive for IA-2Ab. In village 2, no DM subject was GAD65Ab positive. One (10%; 1/10) of the IGT subjects and two (1.6%;2/129) of the healthy controls were positive for GAD65Ab. In this village, two of the DM subjects (12%;2/17), one of the IGT subjects (10%; 1/10), and one of the healthy controls (0.8%;1/129) were IA-2Ab positive. No individual was positive for both GAD65Ab and IA-2Ab. CONCLUSION: Alaskan Inupiat and Siberian Yup'ik Eskimos appear to be predominantly affected by type 2 diabetes, not LADA.
