Abstract The National Institute on Aging-funded Geroscience Education and Training Network held the “Building an Interdisciplinary Workforce in Geroscience: Aligning Perspectives and Educational Goals” preconference workshop at the 2023 Gerontological Society of America’s Annual Meeting. Parties involved in geroscience education and interested stakeholders addressed the development of didactic educational materials, training, and career development opportunities to equip learners with the skills to meet the demands of the emerging field of geroscience, from research to clinic and industry. Recent successes were presented, existing opportunities, gaps, and challenges identified and discussed, and solutions and future directions described.

Background: Cognitive change is an important factor in understanding dementia. Estimating effects of exposures on cognitive change requires choosing an analytical timescale, typically time on study or current age. There is limited consensus regarding timescale choice in epidemiologic cognitive aging research. Methods: Using a coordinated analytic approach in 10 cohorts of older adults, we evaluated whether estimated effects of two exposures on memory change differed depending on timescale (time on study or current age). We modeled effects of apolipoprotein-E (APOE) ε4 genotype (a time-invariant exposure) and diabetes (a potentially time-varying/acquired exposure evaluated at baseline) using mixed-effects models with linear and nonlinear time specifications for both timescales. Results: Among APOE ε4 carriers, model-estimated memory scores at baseline (time on study timescale) or at each cohort’s median baseline age (current age timescale) were lower, and the average rate of decline was faster than among APOE ε4 noncarriers. Model-estimated memory scores at baseline or at median baseline age were generally similar across baseline diabetes status, with variability across cohorts in the diabetes-memory change association. In some cohorts, trends in diabetes-memory change associations differed in direction across timescales. Conclusions: Timescale was largely inconsequential for estimated effects of APOE genotype, but yielded differences in estimated diabetes effects, raising questions about the appropriate scale. The current age scale may be problematic because diabetes was measured heterogeneously in age across individuals, a common issue in aging cohorts. Our work demonstrates approaches to evaluate alternative timescales, including in multicohort analyses, and highlights potential implications for estimated exposure effects on cognitive change.

Aortic stenosis is a progressive condition with substantial implications for morbidity and mortality. In recent years, attention has shifted toward risk stratification and the development of individualized management plans to optimize treatment outcomes. The management of asymptomatic patients has become a topic of significant controversy, as emerging studies challenge traditional watchful waiting guidelines and propose the potential benefits of early intervention. While early intervention may reduce overall morbidity and mortality in this patient population, the associated procedural risks remain a critical consideration. This review seeks to analyze the existing literature, offering an updated perspective on patient risk stratification and evidence evaluating both management approaches.

Background: Latinas with mammographic dense breasts are at increased risk of breast cancer. This randomized controlled trial tests the effectiveness of three breast density (BD) educational approaches on adherence to subsequent mammography screening among Latinas receiving care at a Federally Qualified Health Center (FQHC). Measure(s): Adherence was ascertained using electronic health record and survey responses. Kaplan–Meier estimates of the time to subsequent mammogram were used to obtain adherence rates at 1- and 2-years post baseline mammogram. Cox modeling assessed whether adherence differed by patient characteristics or group assignment. Results: This analysis was limited to Latinas enrolled between October 27, 2016, and December 21, 2018 ( n = 946; 66.1% <50 years of age, 53.5% with dense breasts). Adherence rates at 1 year was 24.8% increasing to 51.7% by year 2. Latinas randomized to the Promotora + brochure + letter arm (hazard ratio [HR]: 1.09 [95% confidence interval [95% CI] 0.87 to 1.36]) or brochure + letter (HR: 1.03 [95% CI 0.82 to 1.29]) arm were not more likely to be adherent to subsequent mammography compared to the letter only arm ( p = 0.76) . Adjusting for age and study group, having more prior mammograms, being “extremely likely” to get an annual mammogram, and having more confidence to get an annual mammogram at baseline were significant drivers of subsequent adherence. Conclusion: Informational interventions targeting BD education alone are unlikely to significantly improve adherence to subsequent mammography among Latinas receiving care in FQHCs.

Purpose The Sangre Por Salud (SPS) Biobank was established to facilitate biomedical research opportunities for the Latino community by creating an easily accessible prospective cohort for scientists interested in studying health conditions and health disparities in this population. Participants Individuals self-identifying as Latino, aged 18–85 years, were prospectively recruited from the primary care Internal Medicine clinic at Mountain Park Health Center in Phoenix, Arizona. After obtaining informed consent, detailed medical history questionnaires were captured, and blood samples were obtained for common laboratory tests. Participants authorised the research team to access their electronic health records for research purposes. In addition, participants had serum, plasma and DNA samples isolated and stored at the Mayo Clinic Arizona Biorepository Laboratory for long-term storage and future access. As part of the study, participants consented and agreed to be contacted for potential participation in future research studies. Findings to date 3756 participants provided informed consent, of whom 3733 completed all study questionnaires, an oral glucose tolerance test and had blood collected and stored. The SPS cohort is predominantly composed of females (72%), with a median age at time of consent of 42 years. All participants self-identified as Hispanic/Latino, 45% were married, 53% were employed for wages and 60% had less than a high school degree. Around 25% of participants met diagnostic criteria for overweight (BMI 25–29 kg/m 2 ), and 49% met for obesity (BMI≥30 kg/m 2 ). At time of recruitment, hypertension, hyperlipidaemia and depression affected 22%, 20% and 13% of the cohort, respectively. Future plans We plan to regularly update the participants’ electronic health records and self-reported health data to longitudinal research. Additionally, we plan to obtain a more comprehensive genomic analysis on the entire cohort, ensuring greater research interest and investigation into the underlying genetic factors that contribute to disease susceptibility in this cohort.

BACKGROUND: Increased specialty competitiveness, alongside the inception of virtual interviews, has increased the number of applications submitted to the Electronic Residency Application Service (ERAS) in anesthesiology. ERAS introduced signals to provide applicants with a means to demonstrate interest in a select group of residency programs. In the 2023 to 2024 application cycle, anesthesiology applicants had the opportunity to send 5 gold and 10 silver signals in a tiered system. METHODS: This multicenter, cross-sectional (exempt) research survey was created by members of the executive council of the Association of Anesthesiology Core Program Directors (AACPD) and housed and distributed through REDCap and the University of Nebraska Medical Center. Publicly available contact information of anesthesiology core program directors was obtained from the Accreditation Council for Graduate Medical Education (ACGME) website and membership roster of the AACPD. In total, 174 anesthesiology programs were identified. A survey invitation was distributed on March 12, 2024, to all programs via e-mail with reminders. The survey closed on April 30, 2024. Survey responses were collected anonymously, with instructions to provide 1 response per program. All statistical summaries and analyses were performed using SAS 9.3 (SAS Institute). RESULTS: The survey was sent to all 174 identified programs, with a response rate of 48.9%. Small programs were defined as having <44 residents, medium 44 to 62 residents, and large >62 residents. Small programs received significantly fewer applications (median 1255) than medium (1420) and large (1558) programs ( P = .0005). There was a statistically significant difference in the number of gold signals received based on program size, with large programs receiving significantly more than medium (169 vs 116, P = .0238) or small programs (168 vs 71, P < .0001). Applicants sending gold signals were more likely to receive an interview compared to those who sent silver signals (56.7% vs 31%, P ≤ .0001). Of the those interviewed, applicants who sent gold signals comprised 42% (28.7%–52.6%), whereas applicants who sent silver signals comprised 45.5% (33%–54.7%). Applicants who did not send a program signal but signaled geographically made up a smaller portion of the interview group at 3% (0%–15.4%). The percentage of matched residents sending gold signals made up 66.7% (47.1%–82.4%) of a program’s match list, whereas those sending silver signals were 25% (11.1%–33.3%) of the matched cohort. CONCLUSIONS: Anesthesiology applicants who sent program signals were selected for a large majority of available interview positions, and interviewed applicants who submitted gold and silver signals comprised the vast majority of matched resident cohorts.

AbstractAimWe investigated whether a commercial bi‐level positive airway pressure (BPAP) device, would improve peripheral oxygen saturation (SpO2) during recreational aviation up to 12,500 feet without supplemental oxygen. Ten adults with recreational flight experience (age:47 ± 14; female = 5) completed a standardized flight profile in an unpressurised aircraft, involving randomized crossover design at 8,000 feet and 12,500 feet with BPAP or control. SpO2, middle cerebral artery velocity (MCAv), heart rate (HR), respiratory rate (RR), and relative tidal volume (TV) index were measured continuously. Psychomotor vigilance test (3‐min) assessed reaction time halfway through taxi and altitude stages. Altitude significantly (p < 0.05) decreased mean SpO2, MCAv, and RR, and increased TV index and HR. There was no effect of altitude (p > 0.05) on reaction time. BPAP increased mean SpO2 at 8,000 feet [Control: 92 ± 1%; BPAP: 94 ± 2%; mean difference (MD) = 2 ± 2%; p = 0.002] and 12,500 feet [Control: 86 ± 4%; BPAP: 89 ± 4%; MD = 2 ± 3%; p = 0.013]. BPAP lowered MCAv at 8,000 feet [Control: 53 ± 10 cm/s; BPAP: 50 ± 9 cm/s; MD = ‐3 ± 2 cm/s; p = 0.001] and 12,500 feet [Control: 52 ± 10 cm/s; BPAP: 50 ± 8 cm/s; MD = ‐2 ± 3 cm/s; p = 0.041]. BPAP increased TV index at 8,000 feet (Control: 6.6 ± 1.3; BPAP:8.1 ± 1.8; MD = 1.9 ± 0.8; p < 0.001) but not 12,500 feet, without effect on RR or reaction time. This study provides preliminary results that BPAP may improve mean SpO2 for recreational aviators up to 12,500 feet without supplemental oxygen.

Background: Osteochondritis dissecans (OCD) of the knee is a focal idiopathic alteration of subchondral bone and/or its precursor with risk for instability and disruption of adjacent cartilage. Treatment options focused on preventing premature osteoarthritis vary depending on multiple patient and lesion characteristics, including lesion mobility. Purpose: To differentiate lesion mobility before arthroscopy using a multivariable model that includes patient demographic characteristics and physical examination findings. Study Design: Cohort study (Diagnosis); Level of evidence, 2. Methods: Demographic, preoperative physical examination, and radiographic data were collected from a multicenter national prospective cohort of patients with OCD of the knee. Inclusion criteria included patients <19 years of age and patients with arthroscopically confirmed mobility status based on the Research on Osteochondritis Dissecans of the Knee arthroscopy classification. Multivariable logistic regression analysis using stepwise model selection was used to determine factors associated with the likelihood of a mobile versus an immobile lesion. A 75% partition of the data was used for model training, and 25% was used as a validation cohort. Quantitative model fit statistics were computed using the holdout data, including sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC), along with the corresponding 95% CI. Results: A total of 407 patients in the prospective cohort met inclusion criteria, and 62% were male. The mean ± SD age was 13.7 ± 2.2 years, height 161.8 ± 5.3 cm, and weight 59.2 ± 42.2 kg. Arthroscopic evaluation yielded 235 immobile and 172 mobile lesions. Multivariable analysis determined that the best model to predict lesion mobility included chronologic age ≥14 years ( P < .001), effusion on physical examination ( P < .001), and any loss of range of motion on physical examination ( P = .07), while controlling for male sex ( P = .38) and weight >54.4 kg ( P = .12). In the 25% holdout validation sample (n = 102), a sensitivity of 83%, a specificity of 82%, and an AUC of 0.89 (95% CI, 0.82-0.95) were achieved with these predictive factors. Conclusion: Age, effusion, and loss of motion can predict knee OCD lesion mobility at the time of arthroscopy. Education about lesion mobility can help with surgical planning and patient and family counseling.

Background: Adolescents and young adults (AYAs) living with advanced cancer may experience a heightened risk for existential distress. Addressing AYAs’ hopes can stimulate a dialogue about their concerns, values, and goals, provide a path to holistically support their existential needs, and potentially alleviate their distress. This study aimed to evaluate hope's role in a sample of AYAs living with advanced cancer. Method: This study used a Husserlian phenomenology-informed descriptive qualitative research design to elicit AYAs’ experiences with hope while living with advanced cancer. Participants were virtually recruited from an academic medical center and an online non-profit organization. Thematic analyses were performed across the data set to identify final themes. Results: Fifteen AYAs aged 12–21 years diagnosed with advanced hematological (80%) or solid (20%) malignancies participated in this study. A main theme of Simple Supports of Hope with a subtheme of Diversion was identified. Participants described music as a form of diversion, which supported their hope. Participants found listening to music calming and comforting and helped them cope with their distress. Performing music provided a creative outlet for negative feelings associated with cancer treatment. Participants reported creating music transformed and deintensified the treatment environment and helped spread hope to healthcare staff. Discussion: AYAs may intentionally use music to improve emotional expression, empowerment, connection, and coping strategies throughout the treatment process for cancer. Additional research needs to be conducted exploring the use of music interventions such as therapeutic songwriting or compositional music therapy to assist AYAs with building coping strategies during treatment for cancer.

ImportanceThe American College of Surgeons (ACS) operative standards were established to detail critical elements of cancer surgery, reduce technical variation, and improve outcomes. Two of the 6 operative standards target adequate axillary surgery for breast cancer. The potential association of the operative standards with short-term oncologic outcomes, such as nodal yield and nodal positivity rates, is currently unknown.ObjectiveTo evaluate the potential association of the ACS operative standards with short-term oncologic outcomes in breast cancer.Design, Setting, and ParticipantsA cohort study was performed using data on 1 201 317 women 18 years or older who underwent sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) for invasive breast cancer from January 1, 2012, to December 31, 2020. Patients were identified using the National Cancer Database (NCDB), a clinical oncology database encompassing approximately 70% of new cancer diagnoses, sourced from hospital registry data from 1317 facilities. Statistical analysis was performed from October 2023 to June 2024.ExposureSentinel lymph node biopsy or ALND.Main Outcomes and MeasuresReliability-adjusted facility-level lymph node yield and nodal positivity rate for each procedure were calculated using generalized linear mixed models, Poisson regression, and logistic regression with facility-level random intercepts.ResultsThe cohort included 1 201 317 women with a median age of 62 years (IQR, 53-70 years). Facility-level nodal yield ranged from 1 to 6 for SLNB and from 6 to 22 for ALND. Median facility-level nodal yield for SLNB was 2.6 (IQR, 2.3-3.0) and the nodal positivity rate for SLNB was 12.2% (IQR, 11.0%-13.7%), with rates ranging from 6% to 21%. A weak correlation between facility-level lymph node yield and nodal positivity was observed (Spearman correlation coefficient, 0.17). Median nodal upstaging rate (≥4 positive nodes) for ALND was 30.5% (IQR, 26.5%-35.0%), with rates ranging from 11% to 54%; median nodal yield was 12.2 (IQR, 10.9-13.6). A strong correlation between nodal yield and nodal upstaging rates was observed (Spearman correlation coefficient, 0.53).Conclusions and RelevanceIn this cohort study of women undergoing axillary surgery for invasive breast cancer, facility-level variation in lymph node yield was present for both SLNB and ALND, which could potentially be improved through the ACS operative standards. However, this variation had mixed associations with nodal positivity and upstaging rates, suggesting the association of the ACS operative standards with oncologic outcomes may be mixed.
