Background: Baseline concussion testing can be helpful to perform when providing concussion care for young athletes. To appropriately interpret these data, it is important to understand how certain factors may affect concussion testing. Purpose: To examine the relationship of sociodemographic and health variables with baseline concussion testing in young athletes. Study Design: Cross-sectional study; Level of evidence, 3. Methods: High school and middle school athletes competing in sports or positions at high risk for concussion (football, soccer, ice hockey, wrestling, lacrosse, and pitchers/catchers in baseball/softball) during the 2020-2021 or 2021-2022 academic years completed annual baseline concussion testing and were included in the study. Baseline data included self-reported demographic and medical information, a graded symptom checklist, the Standardized Assessment of Concussion, and the King-Devick test. A validated measure, HOUSES (HOUsing-based index of SocioEconomic Status), was used to determine participants’ socioeconomic status (SES) by linking personal address information to publicly available property data. Multivariable linear regression models were fit to analyze the relationship of concussion baseline testing to sociodemographic and health variables. Results: Among the eligible 2747 athletes (mean age, 15.4 ± 1.5 years; 73.6% male), the mean Standardized Assessment of Concussion score was 26.7 ± 2.0 and the mean best King-Devick test time was 50.3 ± 10.1 seconds. Higher baseline symptom severity scores were related to lower SES ( P = .002). A lower (ie, poorer) mean Standardized Assessment of Concussion score was significantly associated with the following in the multivariable model: male sex ( P < .001), younger age ( P < .001), Black/African American race ( P = .029), Hispanic ethnicity ( P = .016), previous diagnosis of learning disorder or attention-deficit hyperactivity disorder ( P < .001), and lower SES ( P = .003). A higher (ie, poorer) mean King-Devick test time was related to younger age, previous diagnosis of a learning disorder or attention-deficit hyperactivity disorder, and lower SES (all P < .001). Conclusion: Baseline concussion testing was found to be associated with certain sociodemographic variables and underlying health conditions in high school and middle school athletes.

Abstract Background Context Surgical decompression is the definitive treatment for managing symptomatic lumbar spinal stenosis; however, select patients are poor surgical candidates. Consequently, minimally invasive procedures have gained popularity, but there exists the potential for failure of therapy necessitating eventual surgical decompression. Purpose To evaluate the incidence and characteristics of patients who require surgical decompression following minimally invasive procedures to treat lumbar spinal stenosis. Study Design/Setting Retrospective review. Patient Sample Patients who underwent minimally invasive procedures for lumbar spinal stenosis (Percutaneous Image‐guided Lumbar Decompression [PILD] or interspinous spacer device [ISD]) and progressed to subsequent surgical decompression within 5 years. Outcome Measures The primary outcome was the rate of surgical decompression within 5 years following the minimally invasive approach. Secondary outcomes included demographic and comorbid factors associated with increased odds of requiring subsequent surgery. Methods Patient data were collected using the PearlDiver‐Mariner database. The rate of subsequent decompression was described as a percentage while univariable and multivariable regression analysis was used for the analysis of predictors. Results A total of 5278 patients were included, of which 3222 (61.04%) underwent PILD, 1959 (37.12%) underwent ISD placement, and 97 (1.84%) had claims for both procedures. Overall, the incidence of subsequent surgical decompression within 5 years was 6.56% (346 of 5278 patients). Variables associated with a significantly greater odds ratio (OR) [95% confidence interval (CI)] of requiring subsequent surgical decompression included male gender and a prior history of surgical decompression by 1.42 ([1.14, 1.77], p = 0.002) and 2.10 times ([1.39, 3.17], p < 0.001), respectively. In contrast, age 65 years and above, a diagnosis of obesity, and a Charlson Comorbidity Index score of three or greater were associated with a significantly reduced OR [95% CI] by 0.64 ([0.50, 0.81], p < 0.001), 0.62 ([0.48, 0.81], p < 0.001), and 0.71 times ([0.56, 0.91], p = 0.007), respectively. Conclusions Minimally invasive procedures may provide an additional option to treat symptomatic lumbar spinal stenosis in patients who are poor surgical candidates or who do not desire open decompression; however, there still exists a subset of patients who will require subsequent surgical decompression. Factors such as gender and prior surgical decompression increase the likelihood of subsequent surgery, while older age, obesity, and a higher Charlson Comorbidity Index score reduce it. These findings aid in selecting suitable surgical candidates for better outcomes in the elderly population with lumbar spinal stenosis.

Abstract Glioblastoma (GBM) tumors contain a subpopulation of glioma stem cells (GSC) which can escape therapeutic effects through self-renewal and invasion. Epidermal growth factor receptor (EGFR) mutations are the most common alteration in GBM. EGFRvIII (deletion of exons 2-7) is observed in GBM (20-25%) resulting in a constitutively activated EGFR receptor. In addition, extracellular domain missense point mutations, (e.g. G598V, A289V, R108K) are observed in GBM (14.4%). These missense mutations in the EGFR extracellular domain also induces a highly active receptor by enhancing ligand binding. Earlier reports have shown that these EGFR missense point mutations have exhibited therapeutic resistance; however, the molecular mechanism of these missense point mutations in GBM remains unknown. Previous studies in our lab showed that EGFRvIII promotes GSC maintenance and therapeutic resistance via oligodendrocyte transcription factor 2 (OLIG2) signaling. OLIG2 is universally expressed in glioma and essential for reprogramming GBM cells into stem-like tumor cells. Increased OLIG2 expression promotes invasion, growth, proliferation, and survival. Here we report an increase in OLIG2 protein expression in GSCs harboring EGFR-G598V or EGFR-A289V mutations, suggesting these mutations may support stemness properties in GBM tumors. GSC expressing these point mutations display increased self-renewal, growth, and survival. In addition, EGFR-G598V and EGFR-A289V trigger distinct downstream signaling pathways in GSCs to regulate OLIG2 function. Hence, we hypothesize that GBM tumors harboring EGFR missense mutations (G598V, A289V) influence stem cell properties via multiple pathways to evade therapeutic effects and inhibiting these different signaling pathways will decrease therapeutic resistance in GBM. Understanding the mechanism of these EGFR mutations may lead to improved therapeutic strategies for GBM patients.

AbstractBackgroundIt has yet to be fully elucidated how differing populations of obstetric patients adapted to the disruptions in perinatal care and postpartum support from the COVID‐19 pandemic. We surveyed an enriched sample of socioeconomically advantaged patients to understand the influence of COVID‐19 on their perinatal care experience, well‐being, and coping.MethodsWe surveyed pregnant and postpartum patients (n = 6140) at a large academic medical center in the Midwest of the United States using the Coronavirus and Perinatal Experiences instrument in Spring 2021.ResultsThe survey was sent to 6141 pregnant and postpartum patients; 1180 (17.8%) respondents completed the survey, including 256 who were pregnant and 834 postpartum. Most pregnant patients experienced no changes in their prenatal care with 16.5% indicating somewhat worsened care. In the postpartum cohort, 37.5% stated their care had somewhat worsened. In describing influences on stress and mental health, 58.1% of postpartum respondents stated it was moderately, and 17.4% significantly, worse. The pandemic had a somewhat or moderately negative influence for 72.7% of respondents, with 11.0% stating these effects were extremely negative. Both cohorts characterized a range of coping strategies, most commonly, talking with friends and family (76.3%).Conclusion(s)Even among this sample of socioeconomically advantaged patients, respondents indicated that the pandemic disrupted many facets of their medical care and daily life, especially social activities and postpartum support. Our findings suggest that counseling on coping and adaptation strategies for stressors and increased health systems support be part of perinatal care during public health emergencies for all demographic groups.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) have been associated with an increased risk of chronic hypertension for both mothers and offspring. We sought to quantify the incidence of chronic hypertension in offspring from HDP-affected pregnancies in a large, population-based cohort study. Furthermore, we evaluate the association of HDP exposure in utero and maternal chronic hypertension in offspring. METHODS: We performed a population-based cohort study of 8755 individuals born during 1976 to 1982 to 7544 women who all resided in the same community at the time of delivery. HDP were identified using a previously validated algorithm. Diagnosis of chronic hypertension in mothers and their offspring was determined using diagnostic codes. Cox proportional hazards regression was used to assess the association between HDP and chronic hypertension. RESULTS: HDP exposure (hazard ratio, 1.50 [95% CI, 1.18–1.90]) and maternal chronic hypertension (hazard ratio, 1.73 [95% CI, 1.48–2.02]) were both associated with a significant increased risk for chronic hypertension in offspring. Both risk factors remained significantly associated with increased risk of hypertension in offspring when included together in a multivariate model. Having both exposures was associated with a 2.4-fold increase in the risk of hypertension in offspring, suggesting a synergistic additive interaction. CONCLUSIONS: HDP exposure in gestation and maternal hypertension are both independently associated with an increased risk of chronic hypertension in offspring. Our results suggest that HDP exposure in utero, in addition to maternal chronic hypertension, may lead to a greater risk for the development of hypertension in offspring.

Abstract Objective To assess the relationship between ovarian hyperstimulation syndrome (OHSS) and adverse outcomes using population-based data in the United States. The hypothesis is that patients with OHSS were more likely to deliver preterm and more likely to have hypertensive disorders. Methods This retrospective cohort study identified 94 patients with OHSS and 183 matched referents in eight counties in Minnesota. Data were collected regarding pregnancy history, infertility treatment, and pregnancy outcomes. Using the Rochester Epidemiology Project, study subjects were identified from female patients, aged 18 to 49 years, who were diagnosed with infertility from January 2, 1995 to December 1, 2017, and had a pregnancy greater than 20 weeks' gestation. The primary outcome was preterm delivery or hypertensive disorder of pregnancy incidence in the OHSS group when compared with control patients. Chi-squared test, t test, and multivariate logistic models were used where appropriate. Results Patients with OHSS were more likely to deliver preterm (odds ratio, 2.14; 95% confidence interval, 1.26–3.65; P < 0.01), and their neonates were more likely to be small for gestational age (odds ratio, 4.78; 95% confidence interval, 1.61–14.19; P < 0.01). No significant differences between the groups were observed in any other outcome. Patients with OHSS are more likely to deliver preterm if they undergo fresh transfer compared with a freeze all and subsequent frozen transfer (odds ratio, 3.03, 95% confidence interval, 1.20–7.66, P = 0.02). Conclusion OHSS may lead to preterm birth and small-for-gestational-age neonates, which changes patient counseling and leads to arranging specialized obstetrical care for these patients with OHSS.

6548 Background: National organizations (ASCO, ACS, ACCR) have advocated for routine collection of sexual orientation and gender identity (SOGI) in cancer clinics to advance cancer health equity. In 2017, only 24% of NCI Community Oncology Research Program (NCORP) practices collected sexual orientation (SO) data, while 10% collected gender identity (GI) data; recent progress in collection is unknown. Methods: In 2022, NCORP practices again completed a Landscape Assessment to assess research capacity (funding support from 2UG1CA189824) and were asked whether they routinely collect SOGI data in the electronic health record (EHR). The proportions of practices reporting collection of SO and/or GI data and population level differences over time were calculated using Fisher’s exact tests. Univariate associations between SOGI data collection and site-related variables were evaluated using logistic regression; significant associations were then tested in separate multivariate logistic regression models. Results: 271 practices responded to the Landscape Assessment; 42% (114) reported that they routinely collect SO data, 58% (157) reported that they collect GI data; both were significantly higher than 2017 (p<0.001). Compared to other regions, practices in Northeastern states were significantly more likely to report collecting GI, but not SO. Practices with higher proportions of White patients were also more likely to collect GI (p < 0.001). Practices with community outreach staff were more likely to collect SO (Table 1). There were no significant differences in SOGI collection by Medicaid/Medicare patients, new cancer cases per year, or practice ownership. In both 2017 and 2022, sites in Southern states were less likely to collect GI than sites in other regions. Conclusions: Progress was made in SOGI collection between 2017 and 2022, but fewer than half of NCORP sites routinely collect SOGI data, in spite of national guidelines. Further examination of the cultural context of SOGI collection could inform efforts to improve data collection in the South and other regions. The lack of data on sexual and gender minority patients in the EHR contributes to health inequity and deficiencies in patient-centric care. [Table: see text]

Abstract: Background and Aims The BNT162b2 and mRNA-1273 COVID-19 vaccines are efficacious in patients with inflammatory bowel disease; but there is a lack of data examining if holding immunosuppressive therapy around vaccination improves immune response. We studied the effect of holding IBD medications around the time of vaccination on antibody response and breakthrough COVID-19 infection. Methods Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID is a prospective cohort of individuals with IBD receiving COVID-19 vaccination. Quantitative measurement of anti-receptor binding domain IgG antibodies to SARS-CoV-2 was performed 8 weeks after completing a vaccination series. Results A total of 1854 patients were included; 59% were on anti-tumour necrosis factor [TNF] [10% of these on combination therapy], 11% on vedolizumab, and 14% on ustekinumab; 11% of participants held therapy before or after vaccine administration for at least 2 weeks. Antibody levels were similar in participants continuing versus holding anti-TNF monotherapy before or after the second vaccine [BNT162b2: 10 μg/mL vs 8.9 μg/mL; mRNA-1273: 17.5 μg/mL vs 14.5 μg/mL]. Comparable results were seen in those on combination therapy. Antibody titres in those on ustekinumab or vedolizumab were higher compared with anti-TNF users, but there was no significant difference if the drug was held or continued [BNT162b2: 22.5 μg/mL vs 23 μg/mL; mRNA-1273: 88 μg/mL vs 51 μg/mL]. Holding therapy was not associated with decreased rate of COVID-19 infection compared with those not holding therapy [BNT162b2: 28% vs 29%; mRNA-1273: 19% vs 31%]. Conclusion We recommend continuing IBD medications while receiving mRNA COVID-19 vaccination without interruption.

Objectives:Patients with Trisomy 21 (T21) commonly have gastrointestinal symptoms and diseases that prompt evaluation with esophagogastroduodenoscopy (EGD). Our objective is to characterize duodenal histological abnormalities in these patients when undergoing EGD. A secondary aim is to explore associations of histologic findings with different therapies.Methods:Patients 30 years old or younger with T21 who underwent EGD from 2000 to 2020 at 6 hospitals were included in this retrospective cohort study. Duodenal biopsies were categorized based on reported histopathology findings as normal or abnormal. Abnormal pathology reports were reviewed and categorized into villous atrophy (VA) and duodenitis without VA. The VA group was further categorized based on the presence or absence of celiac disease (CD).Results:We identified 836 patients with T21 who underwent EGD, 419 (50.1%) of whom had duodenal histologic abnormalities. At the time of the first (index) abnormal duodenal biopsy, 290 of 419 had VA and of those, 172 of 290 met CD diagnostic criteria, while 118 of 290 did not meet CD criteria (nonspecific VA). Among the patients with an abnormal biopsy, acid suppression at the time of the index biopsy was less common in patients with VA‐CD compared to patients without VA or patients with nonspecific VA (12.2% vs 45.7% vs 44.9%).Conclusions:Half of the T21 patients in this cohort had abnormal duodenal biopsies including a subgroup with nonspecific VA. In this cohort, acid suppression use was more prevalent in patients with abnormalities other than CD.

BACKGROUND: Respiratory therapists (RTs) work alongside allied health staff, nurses, and physicians during stressful and traumatic events that can be associated with emotional and physiological implications known as second victim (SV) experiences (SVEs). This study aimed to evaluate SVEs of RTs, including both positive and negative implications. METHODS: RTs within a large academic health care organization across Minnesota, Wisconsin, Florida, and Arizona were asked to participate in an anonymous survey that included the validated Second Victim Experience and Support Tool-Revised to assess SVEs as well as desired support services. RESULTS: Of the RTs invited to participate, 30.8% (171/555) completed the survey. Of the 171 survey respondents, 91.2% (156) reported that they had been part of a stressful or traumatic work-related event as an RT, student, or department support staff member. Emotional or physiologic implications experienced by respondents as SVs included anxiety 39.1% (61/156), reliving of the event 36.5% (57/156), sleeplessness 32.1% (50/156), and guilt 28.2% (44/156). Following a stressful clinical event, 14.8% (22/149) experienced psychological distress, 14.2% (21/148) experienced physical distress, 17.7% (26/147) indicated lack of institutional support, and 15.6% (23/147) indicated turnover intentions. Enhanced resilience and growth were reported by 9.5% (14/147). Clinical and non-clinical events were reported as possible triggers for SVEs. Nearly half of respondents 49.4% (77/156) indicated feeling like an SV due to events related to COVID-19. Peer support was the highest ranked form of desired support following an SVE by 57.7% (90/156). CONCLUSIONS: RTs are involved in stressful or traumatic clinical events, resulting in psychological/physical distress and turnover intentions. The COVID-19 pandemic has had a significant impact on RTs’ SVEs, highlighting the importance of addressing the SV phenomenon among this population.
