Abstract The aging process is universal, and it is characterized by a progressive deterioration and decrease in physiological function leading to decline on the organismal level. Nevertheless, a number of genetic and nongenetic interventions have been described, which successfully extend healthspan and lifespan in different species. Furthermore, a number of clinical trials have been evaluating the feasibility of different interventions to promote human health. The goal of the annual Biological Sciences Section of the Gerontological Society of America meeting was to share current knowledge of different topics in aging research and provide a vision of the future of aging research. The meeting gathered international experts in diverse areas of aging research including basic biology, demography, and clinical and translational studies. Specific topics included metabolism, inflammaging, epigenetic clocks, frailty, senescence, neuroscience, stem cells, reproductive aging, inter-organelle crosstalk, comparative transcriptomics of longevity, circadian clock, metabolomics, and biodemography.

Background. The current model for end-stage liver disease (MELD) exception policies for portopulmonary hypertension (POPH) require serial right heart catheterizations (RHCs) every 3 mo to maintain exception points. RHC is necessary for the initial diagnosis of POPH, but the utility of serial catheterizations has not been studied. In patients with POPH MELD exceptions, we sought to compare noninvasive and invasive hemodynamics and determine the sensitivity of echocardiography for the detection of hemodynamically severe POPH that would preclude liver transplant. Methods. We performed a single-center retrospective cohort study of patients with POPH MELD exceptions who underwent liver transplant from December 2008 to January 2024. Results were validated at an external center. Echocardiograms and RHCs performed within 1 mo were compared. Pearson correlation coefficient and Bland-Altman plots assessed the association between echocardiogram and RHC variables. We examined varied echocardiographic parameters to optimize sensitivity for the detection of hemodynamically severe POPH. Results. Twenty-two individuals underwent 60 follow-up RHCs with paired echocardiograms. Right ventricular systolic pressure (RVSP) and cardiac index estimated with echocardiogram were not strongly correlated with RHC measurements at follow-up (RVSP and RHC pulmonary artery systolic pressure: R = 0.30, P = 0.02; cardiac index: R = 0.17, P = 0.21). However, echocardiograms with RVSP ≥48 mm Hg had 100% sensitivity for detecting hemodynamically severe POPH, with 100% negative predictive value. In external validation of 13 paired echocardiograms and RHCs, our algorithm had 64% specificity and 100% negative predictive value. Conclusions. Although echocardiogram and RHC hemodynamic estimates were not strongly correlated, these results could potentially negate the current requirement for repeat RHC every 3 mo to maintain POPH MELD exception.

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.

ABSTRACT Background There has been a lack of updated epidemiological data on the incidence and survival outcomes for patients with small cell lung cancer (SCLC) in the United States over the last two decades. Methods A retrospective, population‐based study was conducted utilizing the Surveillance, Epidemiology, and End Results (SEER) program to identify patients with SCLC from 2000 to 2020. Trends in cancer incidence, incidence‐based mortality rates, 1‐year relative survival rates and 1‐year observed survival were evaluated utilizing the SEER database. Results The database identified a total of 188,426 SCLC patients during the study period from 2000 through 2020. The age‐adjusted incidence rate slowly declined, on average, by 3% (95% CI: −3.2% to −2.8%) each year from 9 per 100,000 in 2000 to 4.6 per 100,000 in 2020. The decline is evident for all age groups, sexes, and races. Incidence‐based mortality also declined slowly from 6.6 in 2005 to 3.5 in 2020. However, survival outcomes, including 1‐year relative survival and 1‐year observed survivals, have not improved significantly over the last two decades. Conclusion This study found that the incidence of SCLC has decreased from 2000 to 2020, likely due to a reduction in smoking rates, underscoring the importance of smoking abstinence. An improvement in incidence‐based mortality is likely related to an enhanced medical care and a decrease in the incidence of SCLC, but the lack of improvement in survival outcomes reflects the need for more effective systemic therapy.

BACKGROUND: Ventral rectopexy has become increasingly used in the surgical management of rectal prolapse. There is a need for a contemporary evaluation of the role of the procedure and a description of its use in clinical practice. OBJECTIVE: To create an international consensus on ventral rectopexy. DESIGN: An expert panel undertook a scoping review of the literature to identify subject domains of interest. Literature reviews were completed for each domain with subsequent development of evidence-based and practice-based statements. These statements were compiled and reviewed by the group over a total of 9 meetings. Once statements were confirmed, supportive text was finalized, and an anonymous vote was completed using Research Electronic Data Capture to record consensus. SETTING: An international expert panel comprising colorectal surgeons who perform ventral rectopexy in a high-volume center. MAIN OUTCOME MEASURES: Statements and associated expert consensus. RESULTS: Eleven experts identified 10 domains for review: indications, contraindications, assessment and planning, consent, operative details, prostheses, complications, follow-up, recurrence and reoperative surgery, and specific considerations. After round table review, there were 17 resultant statements for consideration. Experts agreed unanimously with 13 of the statements and their accompanying text, with different experts disagreeing regarding the remaining 4 statements (91% consensus each). LIMITATIONS: Paucity of high-quality data. CONCLUSIONS: This international group developed 17 statements with high consensus. These statements provide an up-to-date summary of the literature, identify key areas for research development, and provide a reference point for colon and rectal surgeons who undertake ventral rectopexy as part of their practice.

Abstract Background The opioid crisis and the increasing prevalence of multi-drug resistant organism (MDRO) infections pose a threat to public health. Opioid Use Disorder (OUD) patient are prone to MDRO colonization and infections, thus potentially leading to adverse outcomes during periods of critical illness. Understanding the prevalence and predictors of MDRO infections within this vulnerable population is critical to improving patient outcomes by optimizing interventions and treatment plans. Methods We conducted a retrospective, multicenter, cohort study to evaluate the prevalence of MDRO isolation among adults with OUD admitted to an intensive care unit (ICU) with an infection across four Mayo Clinic regions. Patients were classified to the MDRO cohort if an MDRO was isolated from standard cultures or rapid diagnostic testing within 48 hours of admission. We utilized descriptive statistics, univariate and multivariate least absolute shrinkage and selection operator (LASSO) regression analysis including random effect to account for site variability, to analyze demographic data, clinical characteristics, and outcomes. Results 790 critically ill adult OUD patients with infection-related admission were included in the study cohort. The prevalence of MDRO isolation was 22.5% (n=178), with MRSA being the predominant isolated MDRO. In LASSO regression analyses, we identified homelessness (OR: 1.79, p = 0.022), no Medications for OUD (MOUD) treatment (OR: 1.56, p=0.023), and positive Hepatitis C Virus (HCV) status (OR: 2.19, p = 0.012) as significant predictors for isolation of an MDRO. Intravenous (IV) antibiotic use in the preceding 90 days was also positively associated (OR: 1.04 per 24 hours, p = 0.007), alongside mental health disorders (OR: 2.03, p &lt; 0.001) and diabetes (OR: 1.54, p = 0.023). Conclusion The high prevalence of MDRO isolation in critically ill OUD patients with infection is associated with complex social and clinical factors. Disclosures All Authors: No reported disclosures
