Abstract: Objectives: Policy-makers rarely consult adolescents during development of health policies. However, perspectives of adolescents on health can inform public health policies and programs. As part of the development of an Indiana state plan for adolescent health, we used qualitative methods to describe adolescents'' “emic” views of health, and discuss implications for a state health policy for youth. Patients and Methods: We conducted eight adolescent focus groups in geographically and culturally diverse regions of Indiana. Each group was audio-recorded, transcribed, and analyzed using qualitative methods. Results: Participants described health as a shared responsibility between adolescents and adults in their lives. They identified a key role for supportive adults in initiating and maintaining health behaviors. Physical, financial, and informational environments could support or hinder healthy behaviors and outcomes. Although adolescents'' descriptions of physical health and risk behaviors were similar to adult formulations, they described mental health as “stress and fatigue,” an interaction between the adolescent and their environment, rather than depression and anxiety which are considered to be individual pathologies. Respect for decision-making capacity, seeking adolescent input, and providing harm reduction messages were identified as particularly important. Conclusions: Adolescent''s perception of health can inform policies and programs, and should be sought before the development of health policies. [Copyright &y& Elsevier]

Sexual and gender minority (SGM) adverse childhood experiences (ACEs) are identity-based forms of early life adversity. Exposure to SGM ACEs is associated with increased odds of depression, anxiety, and post-traumatic stress disorder in SGM adults. The purpose of this study was to further test a revised version of the measure in a U.S. sample with more robust and clinically relevant mental health outcomes. In May and June 2022, a national sample of SGM adults (N=4,445) was recruited from a Qualtrics Panel to complete a 20-minute online survey that included questions regarding ACEs, SGM ACEs, depression, anxiety, and post-traumatic stress disorder. Exploratory factor analysis and confirmatory factor analysis were used to examine factor structure. Multivariable regression was used to assess criterion validity, and a sensitivity analysis was conducted. Data were analyzed in February 2023. Respondents indicate that vicarious trauma (81%) and school bullying (67%) were the most common experiences and that all SGM ACEs were frequently occurring before adulthood. Confirmatory factor analysis determined a 1-factor solution. Participants with more SGM adverse childhood experiences exposure had worse anxiety, depression, and post-traumatic stress disorder symptoms (β=0.16, β=0.18, β=0.26, respectively, p <0.0001) after controlling for ACEs exposure and demographic factors. A sensitivity analysis indicated that estimates were similar in terms of magnitude and direction. SGM ACEs commonly and frequently occur before adulthood and impact adult SGM mental health. Overall, the measure had good-to-excellent psychometric properties. Future research should consider integrating SGM ACEs and Minority Stress Theory. [ABSTRACT FROM AUTHOR]

Abstract: [11C]Hemicholinium-15 ([11C]HC-15) and [18F]hemicholinium-15 ([18F]HC-15) have been synthesized as new potential PET tracers for the heart high-affinity choline uptake (HACU) system. [11C]HC-15 was prepared by N-[11C]methylation of the appropriate precursor, 4-methyl-2-phenyl-morpholin-2-ol, using [11C]CH3OTf in 55–70% radiochemical yield decay corrected to end of bombardment (EOB) and 2–3Ci/μmol specific activity at end of synthesis (EOS). [18F]HC-15 was prepared by N-[18F]fluoromethylation of the precursor using [18F]FCH2OTf in 20–30% radiochemical yield decay corrected to EOB and >1.0Ci/μmol specific activity at EOS. The biodistribution of both compounds was determined in rats at 20min post-intravenous injection, and the results show the heart region uptakes 1.32±0.75%ID/g in R-ventricle for [11C]HC-15 and 1.28±0.81%ID/g in L-ventricle for [18F]HC-15, respectively. The dynamic PET imaging studies of [11C]HC-15 in rats were acquired 60min post-intravenous injection of the tracer using the IndyPET-II scanner. For the blocking experiments, the rats were intravenously pretreated with 3.0mg/kg of unlabeled HC-15 prior to [11C]HC-15 injection. [11C]HC-15 rat heart PET studies show rapid heart uptake to give clear heart images. The rat heart PET blocking studies found no significant blocking effect. The dynamic PET studies in normal and ablated dogs were performed using Siemens PET scanner with [13N]NH3, [11C]HC-15, and [18F]HC-15. PET studies in dogs of both [11C]HC-15 and [18F]HC-15 also show significant heart uptake and give images of the heart. However, there is no significant change in [11C]HC-15 L-ventricle uptake following radiofrequency ablation in the dog. These results suggest that the localization of HC-15 tracers in the heart is mediated by non-specific processes, and the visualization of HC-15 tracers on the heart is related to non-specific binding of HACU.
