Objective: To identify patterns (“classes”) of outcomes for adults with and without childhood ADHD. Method: Subjects were 232 childhood ADHD cases and 335 non-ADHD referents from a 1976 to 1982 birth cohort. We used latent class analyses to identify classes based on a broad array of adult psychosocial outcomes and determined the proportion of subjects with childhood ADHD within each class. Results: A three class solution provided optimal model fit; classes were termed “good,” “intermediate,” and “poor” functioning. Subjects with childhood ADHD comprised 62.8% of the “poor,” 53.5% of the “intermediate,” and 24.9% of the “good” functioning class. The “poor” functioning class was distinguished by increased likelihood of legal trouble and substance use disorders and included more individuals with childhood ADHD and psychiatric disorder than the “intermediate” class (45.5% vs. 30.6%). Conclusion: Children with ADHD are at risk for adverse adult outcomes in multiple domains and co-morbid childhood psychiatric disorders increase risk.

On average, there are 3–5 million severe cases of influenza virus infections globally each year. Seasonal influenza vaccines provide limited protection against divergent influenza strains. Therefore, the development of a universal influenza vaccine is a top priority for the NIH. Here, we report a comprehensive summary of all universal influenza vaccines that were tested in clinical trials during the 2010–2019 decade. Of the 1597 studies found, 69 eligible clinical trials, which investigated 27 vaccines, were included in this review. Information from each trial was compiled for vaccine target, vaccine platform, adjuvant inclusion, clinical trial phase, and results. As we look forward, there are currently three vaccines in phase III clinical trials which could provide significant improvement over seasonal influenza vaccines. This systematic review of universal influenza vaccine clinical trials during the 2010–2019 decade provides an update on the progress towards an improved influenza vaccine.

Bioactive surfaces and materials have displayed great potential in a variety of tissue engineering applications but often struggle to completely emulate complex bodily systems. The extracellular matrix (ECM) is a crucial, bioactive component in all tissues and has recently been identified as a potential solution to be utilized in combination with biomaterials. In tissue engineering, the ECM can be utilized in a variety of applications by employing the biochemical and biomechanical cues that are crucial to regenerative processes. However, viable solutions for maintaining the dimensionality, spatial orientation, and protein composition of a naturally cell-secreted ECM remain challenging in tissue engineering. Therefore, this work used soft lithography to create micropatterned polydimethylsiloxane (PDMS) substrates of a three-dimensional nature to control cell adhesion and alignment. Cells aligned on the micropatterned PDMS, secreted and assembled an ECM, and were decellularized to produce an aligned matrix biomaterial. The cells seeded onto the decellularized, patterned ECM showed a high degree of alignment and migration along the patterns compared to controls. This work begins to lay the groundwork for elucidating the immense potential of a natural, cell-secreted ECM for directing cell function and offers further guidance for the incorporation of natural, bioactive components for emerging tissue engineering technologies.

AbstractIntroductionMicrostructural alterations as assessed by diffusion tensor imaging (DTI) are key findings in both Alzheimer's disease (AD) and small vessel disease (SVD). We determined the contribution of each of these conditions to diffusion alterations.MethodsWe studied six samples (N = 365 participants) covering the spectrum of AD and SVD, including genetically defined samples. We calculated diffusion measures from DTI and free water imaging. Simple linear, multivariable random forest, and voxel‐based regressions were used to evaluate associations between AD biomarkers (amyloid beta, tau), SVD imaging markers, and diffusion measures.ResultsSVD markers were strongly associated with diffusion measures and showed a higher contribution than AD biomarkers in multivariable analysis across all memory clinic samples. Voxel‐wise analyses between tau and diffusion measures were not significant.DiscussionIn memory clinic patients, the effect of SVD on diffusion alterations largely exceeds the effect of AD, supporting the value of diffusion measures as markers of SVD.

AbstractObjectiveWhereas studies in adult epilepsy patients have shown higher rates of suicidal ideation and attempt, such studies in children are limited. Using the Rochester Epidemiology Project database, we compared the risk of self‐injurious behavior and suicidal ideation in a population‐based cohort of childhood epilepsy to controls.MethodsWe studied 339 cases with epilepsy and 678 age‐ and sex‐matched controls followed to a median age of 24.7 and 23.4 years, and identified 98 subjects with self‐injurious behavior or suicidal ideation (43 with epilepsy and 55 controls). All behaviors were categorized using the Columbia Suicide Severity Rating Scale.ResultsThose with epilepsy had a significantly higher rate of any self‐injurious behavior and suicidal ideation (hazard ratio [HR] = 1.56, 95% confidence interval [CI] = 1.04‐2.35) and tended to have an increased risk of suicidal ideation and attempt (HR = 1.48, 95% CI = 0.93‐2.37). The prevalence of preceding mood and substance abuse disorders was similarly high in both cases and controls with self‐injurious behavior or suicidal ideation; however, preceding attention‐deficit/hyperactivity disorder was more than twice as common in the epilepsy cases. Among cases with epilepsy, we did not identify any specific epilepsy‐related variable that was significantly correlated with risk of self‐injurious behavior or suicidal ideation.SignificanceChildren, teens, and young adults with a history of childhood epilepsy are at greater risk of self‐injurious behavior, highlighting the need for careful screening of mental health concerns as part of routine epilepsy care.

American Academy of Pediatrics (AAP) guidelines for children with Down syndrome (DS) include assessment for celiac disease (CD), although data to support this recommendation have been inconsistent. We determined the incidence of CD among children with DS in a population-based birth cohort of children born from 1976 to 2000 in Olmsted County, Minnesota. Individuals with karyotype-confirmed DS and CD (using diagnosis codes, positive serology, and duodenal biopsies) were identified. The incidence of CD in DS was compared with the published incidence of CD for Olmsted County residents (17.4 [95% confidence interval = 15.2-19.6] per 100 000 person-years). Among 45 individuals with DS from the birth cohort, 3 (6.7%) were identified with positive celiac serology and confirmatory biopsies at ages 9, 12, and 23 years, for an incidence of 325 per 100 000 person-years. Thus, individuals with DS have more than 18 times the incidence rate of CD compared with the general population, supporting the AAP guidelines.

INTRODUCTION: Adverse patient events inevitably occur in OB/GYN practice. Health care provider who are “second victims” experience psychological trauma and progress through defined stages of recovery as they process the event. This experience is believed to be an under-recognized, yet prevalent phenomenon. Study aims were to determine the prevalence of second victims and the risk factors for feeling like a second victim among staff caring for OB/GYN patients to guide the implementation of new resources for second victims. METHODS: We administered the validated Second Victim Experience and Support Tool (SVEST) supplemented with non-validated questions to multidisciplinary team members caring for OB/GYN patients at Mayo Clinic in Rochester, MN. Respondents to the self-administered, anonymous survey included physicians, nurse practitioners, physician assistants, certified nurse midwife, registered nurses, allied health professionals, and desk staff. RESULTS: The survey was completed by 205 staff (117 OB only, 73 GYN only, 15 both). During their career, 44.8% felt like a second victim while 18.8% had this experience in the last 12 months. Residents and fellows had the highest percentage of second victims (41.7%). Respondents who reported greater psychological distress were more likely to report that they felt like a second victim after an adverse patient safety event within the preceding 12 months (p-value<0.001). The same finding was observed for measures of physical distress. CONCLUSION: OB/GYN team members report significant differences in physiological and physical symptoms after adverse events. Understanding and screening for psychological and physical symptoms may be useful in identifying second victims and guiding support following adverse events.

9073 Background: An accumulating body of evidence suggests that the outcome of early-stage melanoma is influenced by endocrine and menopausal status. However, it remains controversial as to whether the superior female melanoma-specific survival (MSS) is restricted to early stage disease or if it also pertains to patients with metastatic melanoma (MM). Methods: We analyzed data from the 13 registries that participate in the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program. We identified all cases of primary invasive melanoma diagnosed between 1992 and 2009; none of the patients had a prior history of another cancer. MSS was compared between males and females, stratified by stage of disease. Age groups were defined as 18-45y, 46-54y, 55-64y, 65+y as a proxy of female menopausal status. Results: The study population included 87,165primary invasive melanoma cases (unstaged n=2834). MSS was significantly poorer for males compared to females for localized (n=72,456) and regional (n=8,945) disease for all age groups (Hazard ratio (HR) ranging from 1.21 to 2.09, all p<0.001). MSS was not significantly different between males and females for patients with distant disease at diagnosis (n= 2930; HR 0.99, 0.92, 1.11, 1.07 for each age group) and remained non-significant after adjusting for Breslow thickness, histologic subtype, anatomic site, and age group (adjusted HR 1.04 males vs. females; 95% CI 0.95-1.14; p=0.41). Conclusions: While our results were consistent with earlier reports that women have higher MSS rates compared to men for early (stage I-III) melanoma, the intriguing finding of this study was that the female survival advantage does not vary with age or menopausal status as compared to men, which is contrary to previously published reports. Furthermore, we found that the difference in survival was no longer significant for patients with MM, suggesting that sex may influence local and regional, but not distant cancer progression.
