    Abstract: The goal of the current study was to better understand the development of gender typicality in young adulthood by applying the dual-identity approach to gender typicality, previously developed with children, to a university sample. Participants ( n = 215, M age = 20.20 years; 62% female) were asked to rate their perceived similarity to both own- and other-gender peers. They also completed questionnaires assessing sexist attitudes, internalized sexualization (females), adherence to male-typed behaviors in the context of interpersonal relationships (males; adherence to physical toughness and restrictive emotional expressivity), gender-based relationship efficacy, friendships, self-esteem, social self-efficacy, and social anxiety. Results indicated that self-perceived gender typicality involves comparisons to both gender groups, and that meaningful typologies can be created based on similarity to own- and other-gender groups. As with children, results indicated that identifying with one’s own gender was advantageous in terms of low social anxiety and relationships with own-gender peers. For adults who identified with both own- and other-gender peers, we identified additional social benefits (i.e., efficacy and friendships with other-gender peers). Further, we identified a downside to own-gender typicality: individuals who identified only with their own gender had more sexist attitudes than those who identified with the other gender. Findings support the viability of the dual-identity approach in young adults, and have implications for researchers assessing gender typicality across development.

    Abstract: An active lifestyle with regular exercise is thought to decrease or delay the onset of Alzheimer dementia through increasing blood flow to the brain. We examined the mean flow velocity (MFV) and pulsatility index (PI) in the middle cerebral arteries of individuals randomized into 2 groups—a usual physical activity (UPA) group and an enhanced physical activity (EPA) exercise intervention group—to determine whether exercise training is related to changes in cerebral blood flow. Methods: We examined 23 participants, randomized into a UPA group (n = 12) and an EPA group (n = 11), with transcranial color-coded Doppler (TCCD) and cardiorespiratory fitness (VO 2 peak) testing at baseline and following a 26-week intervention. Transcranial color-coded Doppler was used to measure MFV and PI. Participants in the EPA group completed supervised aerobic exercise training for 26 weeks. Kendall’s tau-b correlation was used to examine relationships between variables. The Wilcoxon rank-sum tests were used to examine changes between the UPA and EPA groups. Results: There was no significant change in MFV or PI in the UPA group or the EPA group ( P values 〉 .05) between baseline and 26 weeks; the change between the UPA and EPA groups was also not significant ( P = .603). There was no evidence of an association between change in VO 2 peak and change in MFV or PI (all P values 〉 .05). Participants in the EPA group significantly increased their VO 2 peak compared with the UPA group ( P = .027). Conclusion: This study did not demonstrate evidence of a significant change in the MFV in the middle cerebral arteries or evidence of a significant change in the PI between UPA and EPA groups. Future studies should be performed in larger cohorts and should consider use of personalized exercise programs to maximize understanding of how cerebrovascular hemodynamics change in structure and function with exercise for adults at risk of Alzheimer dementia.

    Abstract: With more than 6000 attendees between in-person and virtual offerings, the American Epilepsy Society Meeting 2022 in Nashville, felt as busy as in prepandemic times. An ever-growing number of physicians, scientists, and allied health professionals gathered to learn a variety of topics about epilepsy. The program was carefully tailored to meet the needs of professionals with different interests and career stages. This article summarizes the different symposia presented at the meeting. Basic science lectures addressed the primary elements of seizure generation and pathophysiology of epilepsy in different disease states. Scientists congregated to learn about anti-seizure medications, mechanisms of action, and new tools to treat epilepsy including surgery and neurostimulation. Some symposia were also dedicated to discuss epilepsy comorbidities and practical issues regarding epilepsy care. An increasing number of patient advocates discussing their stories were intertwined within scientific activities. Many smaller group sessions targeted more specific topics to encourage member participation, including Special Interest Groups, Investigator, and Skills Workshops. Special lectures included the renown Hoyer and Lombroso, an ILAE/IBE joint session, a spotlight on the impact of Dobbs v. Jackson on reproductive health in epilepsy, and a joint session with the NAEC on coding and reimbursement policies. The hot topics symposium was focused on traumatic brain injury and post-traumatic epilepsy. A balanced collaboration with the industry allowed presentations of the latest pharmaceutical and engineering advances in satellite symposia.

    Abstract: The rate of anterior cruciate ligament reconstruction (ACLR) in pediatric/adolescent populations has increased over time. However, there is less evidence to support the relative change in concomitant meniscus procedures over time. Demographics and socioeconomic (SES) factors may be implicated in the rate and usage of meniscectomy vs. meniscal repair as treatment. Hypothesis/Purpose: The purpose of this study is to assess if the rate of concomitant meniscus procedure with ACLR is increasing and what factors may be contributing to this rise. We hypothesize that age, sex, race/ethnicity, income, or insurance type may affect the rate of concomitant meniscus procedures. Methods: The Pediatric Health Information System (PHIS) Database was queried for all patients 18 years or younger who underwent ACLR with or without concomitant meniscus procedures based on CPT code from 2015-2019. Data from 39 out of 52 centers were included based on completeness of their data. Basic demographic information including age, sex, self-identified race/ethnicity, and insurance status was collected. Urban and rural designation was identified based on rural-urban commuting area (RUCA) codes. Based on the 2015 Department Health & Human Services Federal Poverty Guidelines (FPL), patients were stratified into lower (≤199% of FPL) and higher (≥200% of FPL) income brackets. Linear regression was used to model trends and multiple logistic regression modeling was used to test for associations. Results: 14,398 patients underwent ACLR during the study period with 8,337 patients (58%) having concomitant meniscal procedures with a 1.24-fold increase over five years (Figure 1). Of the 8,337 patients with concomitant meniscus treatment, 46% had a meniscectomy and 54% had a meniscus repair. There was a 0.86-fold change in meniscectomy and a 1.70-fold increase in meniscus repair during the study period (Figure 2). Males, older patients, Black race, living in an urban area, and those with non-private insurance had increased odds of undergoing a concomitant meniscus procedure (all p 〈 0.05). Patients of Black or other race and those with non-private insurance had increased odds of having a meniscectomy vs. meniscus repair (all p≤0.01). There were no associations detected between income bracket and our outcomes. Conclusions: This study shows that in pediatric and adolescent patients undergoing ACLR, there is a rise in concomitant meniscus procedures from 2015-2019. In addition, patients of non-white race and those with non-private insurance have increased odds of undergoing meniscectomy vs. meniscus repair. This study identifies access and inequality issues in ACLR with concomitant meniscus procedures in pediatric and adolescent populations. [Figure: see text][Figure: see text]

    Abstract: Return-to-sport (RTS) following anterior cruciate ligament reconstruction (ACLR) is influenced by multiple physical and psychological variables. Psychological readiness has been associated with improved patient reported outcomes as well as RTS rates in young athletes. The COVID-19 pandemic may have altered the typical recovery process for patients undergoing ACLR. Hypothesis/Purpose: To compare 6-month postoperative levels of psychological readiness to RTS in ACLR patients before and during the pandemic. Methods: Patients were prospectively enrolled 6 months after primary ACLR at a single academic sports medicine practice, from December 2018 until May 2021. Patients were categorized into pre-COVID (enrollment prior to March 13, 2020) and COVID groups (March 13, 2020 - May 26, 2021). Demographic information, outcomes scores including the ACL-Return to Sport after Injury Scale (RSI) and PROMIS Psychological Stress Experiences (PROMIS-PSE), and physician RTS clearance were obtained and compared for both groups. Comparisons were performed utilizing Chi-square, Student’s t-tests and linear regression. A matched analysis was conducted between groups controlling for age, sex, and graft type. Results: 231 patients were included in the present study (89 males, 142 females; mean age 16.9 years), with 76% (176/231) in the pre-COVID group and 24% (55/231) in the COVID group. There were no significant differences in age and sex between the two population cohorts. There was a significant difference in time from surgery to enrollment in the COVID group compared to the pre-COVID group (7.1 vs 6.2 months, p 〈 0.001). In the matched cohort (n=126, 37/126 COVID group), the COVID group was cleared earlier by their physician to RTS compared to the pre-COVID group (6.9 months vs 8.5 months, p 〈 0.001). While there was no significant difference between groups in 6 month ACL-RSI scores (63.8 pre-COVID vs 66.6 COVID, p=0.48), both groups yielded globally low scores. There were no significant associations between matched groups in PROMIS-PSE (p=0.71), IKDC (p=0.55), Pedi-IKDC (p=0.15), and Pedi-FABS (p=0.77) scores (Table 1). Conclusion: Young athletes demonstrated similar levels of psychological readiness to RTS at 6 months following ACLR prior to and during the COVID-19 pandemic. Patient-reported outcome scores were similar in pre-COVID and COVID ACLR patients, suggesting that the pandemic may not have played a detrimental role in perceptions of recovery. Psychological readiness may not be fully optimized at 6 months post-ACLR and young athletes may benefit from additional time and training for progressive confidence, muscle strength, and performance.

    Abstract: The rate of anterior cruciate ligament (ACL) reconstruction is increasing over time in pediatric/adolescent populations, but there is less evidence to support how concomitant meniscal procedures are changing over time. There are also less data to suggest which characteristics are associated with meniscectomy versus meniscal repair treatment. Hypothesis: Age, sex, race/ethnicity, income, and insurance type may independently affect the rate of concomitant meniscal procedures and treatment modalities in pediatric patients with ACL reconstruction. Study Design: Descriptive epidemiology study. Methods: The Pediatric Health Information System database was queried for all patients aged ≤18 years who underwent ACL reconstruction with or without concomitant meniscal procedures from 2015 to 2019. Basic demographic data including age, sex, self-identified race/ethnicity, rural-urban commuting area code, predicted median income, and insurance status were collected. Linear regression was used to model trends and multiple logistic regression modeling was used to test for associations. Results: A total of 14,398 patients aged ≤18 years underwent ACL reconstruction during the study period, with 8337 patients (58%) having concomitant meniscal procedures with a 1.24-fold increase over 5 years. Of the concomitant meniscal treatment cohort, 41% had a meniscectomy and 59% had meniscal repair. There was a 0.82-fold change in meniscectomy and a 1.67-fold increase in meniscal repair during the study period. Male patients, older patients, Black race, living in an urban area, and those with nonprivate insurance had increased odds of undergoing a concomitant meniscal procedure (all P 〈 .05). Patients of non-White race and those with nonprivate insurance had increased odds of having a meniscectomy versus meniscal repair (all P 〈 .05). There were no associations detected between income bracket and the outcomes in this study. Conclusion: This study shows that in pediatric and adolescent patients undergoing ACL reconstruction, there was a rise in concomitant meniscal procedures from 2015 to 2019. In addition, patients of non-White race and those with nonprivate insurance have increased odds of undergoing meniscectomy versus meniscal repair.

    Abstract: Engineering whole organs from porcine decellularized extracellular matrix and human cells may lead to a plentiful source of implantable organs. Decontaminating the porcine decellularized extracellular matrix scaffolds is an essential step prior to introducing human cells. However, decontamination of whole porcine kidneys is a major challenge because the decontamination agent or irradiation needs to diffuse deep into the structure to eliminate all microbial contamination while minimizing damage to the structure and composition of the decellularized extracellular matrix. In this study, we compared four decontamination treatments that could be applicable to whole porcine kidneys: 70% ethanol, 0.2% peracetic acid in 1 M NaCl, 0.2% peracetic acid in 4% ethanol, and gamma (γ)-irradiation. Porcine kidneys were decellularized by perfusion of 0.5% (w/v) aqueous solution of sodium dodecyl sulfate and the four decontamination treatments were optimized using segments (n = 60) of renal tissue to ensure a consistent comparison. Although all four methods were successful in decontamination, γ-irradiation was very damaging to collagen fibers and glycosaminoglycans, leading to less proliferation of human renal cortical tubular epithelium cells within the porcine decellularized extracellular matrix. The effectiveness of the other three optimized solution treatments were then all confirmed using whole decellularized porcine kidneys (n = 3). An aqueous solution of 0.2% peracetic acid in 1 M NaCl was determined to be the best method for decontamination of porcine decellularized extracellular matrix.
