Abstract
A novel population of age-associated Granzyme K (GZMK)-expressing CD8 T cells was found in mice and humans. These cells enhance local tissue senescence and inflammation and are distinct from central memory and conventional Granzyme B- or Interferon γ-producing effector memory CD8 T cells. It is unknown whether these cells drive chronic disease; thus, we induced atherosclerosis in young (3-mo) and aged (18-mo) wild-type mice via the PCSK9-AAV model and used scRNAseq to demonstrate that this GZMK-CD8 T cell population homes to atherosclerotic lesions exclusively in aged mice. Neutralizing CD8 T cells demonstrates that GZMK-CD8 cells drive age-enhance atherosclerosis. Finally, we transferred GZMK-CD8 cells from different aged donors into young CD8-/- hosts and demonstrate that GZMK-CD8 cells from aged but not young donors drive atherosclerosis. In conclusion, we identified a novel role for this recently described population of aging-specific GZMK-expressing CD8+ T cells as a critical driver of chronic disease.

Abstract
Older people exhibit dysregulated innate immunity to respiratory viral infections, including influenza and SARS-CoV-2, to increase morbidity and mortality. Nanoparticles are a potential practical therapeutic that could divert exaggerated innate immune responses away from the lungs during viral infection. However, such therapeutics have not been examined for effectiveness during respiratory viral infection, particular in aged hosts. Here, we employed a highly lethal model of influenza viral infection in vulnerable aged mice to examine the ability of biodegradable, cargo-free nanoparticles, designated ONP-302, to resolve innate immune dysfunction and improve outcomes during infection. We administered ONP-302 via intravenous injection to aged mice at day 3 post-infection when the hyperinflammatory innate immune response is already established. We found that ONP-302 treatment diverted tissue-damaging inflammatory monocytes from the lungs to the spleen without impacting viral clearance or reducing chemo-attractive signals in the infected lung. Importantly, cargo-free nanoparticles reduced lung damage and histological lung inflammation and improved gas exchange and, ultimately, the clinical outcomes in influenza-infected aged mice. ONP-302 improves outcomes in influenza-infected, vulnerable, aged mice. Thus, our study provides vital fundamental information concerning a practical therapeutic which, if translated clinically, could improve disease outcomes for vulnerable older patients suffering from respiratory viral infections.

Abstract
A quantitative model of the mobility of ligand-presenting particles at the interface is pivotal to understanding important systems in biology and nanotechnology. In this work, we investigate the emerging dynamics of particles featuring ligands that selectively bind receptors decorating an interface. The formation of a ligand-receptor complex leads to a molecular bridge anchoring the particle to the surface. We consider systems with reversible bridges in which ligand-receptor pairs bind/unbind with finite reaction rates. For a given set of bridges, the particle can explore a tiny fraction of the surface as the extensivity of the bridges is finite. We show how, at timescales longer than the bridges' lifetime, the average position of the particle diffuses away from its initial value. We distill our findings into two analytic equations for the sliding diffusion constant of particles carrying mobile and fixed ligands. We quantitatively validate our theoretical predictions using reaction-diffusion simulations. We compare our findings with results from recent literature studies and discuss the molecular parameters that likely affect the particle's mobility most. Our results, along with recent literature studies, will allow inferring the microscopic parameters at play in complex biological systems from experimental trajectories.

Abstract
Purpose Obesity adversely impacts outcomes during COVID-19 but its relation to mortality in those receiving extracorporeal membrane oxygenation (ECMO) is uncertain. Methods A retrospective multicenter study was conducted. Adult patients (≥18 years old) with severe COVID-19 infection placed on ECMO between March 1, 2020 to April 30, 2021, across the United States were included. A web-based database application, REDCap, was utilized to capture clinical characteristics and outcomes. Patients were grouped into tertiles of body mass index (BMI). The primary outcome was in-hospital mortality after ECMO placement assessed by a time-to-event analysis. Results Overall 444 patients (age 49, IQR: 38-57 years, 29% female, BMI: 33, IQR: 29-39 kg/m2) from 17 centers comprised the study cohort. Patients that expired during hospitalization had a similar BMI in comparison to those that were discharged (33, IQR: 29-38 vs. 34, IQR: 30-40 kg/m2, p=0.13). BMI across groups was 27, IQR: 25-29 (lowest tertile), 33, IQR: 32-34 (middle tertile), 41, IQR: 38-45 kg/m2 (highest tertile). At 90 days, in-hospital mortality between BMI tertiles was 53%, 59%, and 53%, p=0.99 (figure). After adjustment for clinical covariates including age, sex, presence of preexisting co-morbidities, cardiopulmonary arrest prior to ECMO, serum creatinine and arterial partial pressure of oxygen (PaO2) to inspired oxygen concentration (FiO2) ratio, there was no difference in hospital mortality in the middle (aHR:1.13, CI: 0.79-1.63, p=0.5) and highest (aHR: 1.38, CI: 0.95-2.01, p=0.09) tertiles in comparison to the lowest BMI tertile. Conclusion Severity of obesity is not associated with death during hospitalization in patients placed on ECMO for COVID-19

Abstract
The HeartWare HVAD System (Medtronic) is a durable implantable left ventricular assist device that has been implanted in approximately 20,000 patients worldwide for bridge to transplant and destination therapy indications. In December 2020, Medtronic issued an Urgent Medical Device Communication informing clinicians of a critical device malfunction in which the HVAD may experience a delay or failure to restart after elective or accidental discontinuation of pump operation. Moreover, evolving retrospective comparative effectiveness studies of patients supported with the HVAD demonstrated a significantly higher risk of stroke and all-cause mortality when compared with a newer generation of a commercially available durable left ventricular assist device. Considering the totality of this new information on HVAD performance and the availability of an alternate commercially available device, Medtronic halted the sale and distribution of the HVAD System in June 2021. The decision to remove the HVAD from commercial distribution now requires the use of the HeartMate 3 left ventricular assist system (Abbott, Inc) if a patient previously implanted with an HVAD requires a pump exchange. The goal of this document is to review important differences in the design of the HVAD and HeartMate 3 that are relevant to the medical management of patients supported with these devices, and to assess the technical aspects of an HVAD-to-HeartMate 3 exchange. This document provides the best available evidence that supports best practices.

Abstract
Stochastic simulation is a key tool in population genetics, since the models involved are often analytically intractable and simulation is usually the only way of obtaining ground-truth data to evaluate inferences. Because of this, a large number of specialized simulation programs have been developed, each filling a particular niche, but with largely overlapping functionality and a substantial duplication of effort. Here, we introduce msprime version 1.0, which efficiently implements ancestry and mutation simulations based on the succinct tree sequence data structure and the tskit library. We summarize msprime’s many features, and show that its performance is excellent, often many times faster and more memory efficient than specialized alternatives. These high-performance features have been thoroughly tested and validated, and built using a collaborative, open source development model, which reduces duplication of effort and promotes software quality via community engagement.

Abstract
BACKGROUND There is little insight into which patients can be weaned off right ventricular (RV) acute mechanical circulatory support (AMCS) after left ventricular assist device (LVAD) implantation. We hypothesize that concomitant RV AMCS insertion instead of postoperative implantation will improve 1-year survival and increase the likelihood of RV AMCS weaning. METHODS A multicenter retrospective database of 826 consecutive patients who received a HeartMate II or HVAD between January 2007 and December 2016 was analyzed. We identified 91 patients who had early RV AMCS on index admission. Cox proportional-hazards model was constructed to identify predictors of 1-year mortality post-RV AMCS implantation and competing risk modeling identified RV AMCS weaning predictors. RESULTS There were 91 of 826 patients (11%) who required RV AMCS after CF-LVAD implantation with 51 (56%) receiving a concomitant RV AMCS and 40 (44%) implanted with a postoperative RV AMCS during their ICU stay; 48 (53%) patients were weaned from RV AMCS support. Concomitant RV AMCS with CF-LVAD insertion was associated with lower mortality (HR 0.45 [95% CI 0.26-0.80], p = 0.01) in multivariable model (which included age, BMI, angiotensin-converting enzyme inhibitor use, and heart transplantation as a time-varying covariate). In the multivariate competing risk analysis, a TPG < 12 (SHR 2.19 [95% CI 1.02-4.70], p = 0.04) and concomitant RV AMCS insertion (SHR 3.35 [95% CI 1.73-6.48], p < 0.001) were associated with a successful wean. CONCLUSIONS In patients with RVF after LVAD implantation, concomitant RV AMCS insertion at the time of LVAD was associated with improved 1-year survival and increased chances of RV support weaning compared to postoperative insertion.

Abstract
Background Cancer-related fatigue, mood disturbances, pain and cognitive disturbance are common after adjuvant cancer therapy, but vary considerably between individuals despite common disease features and treatment exposures. A genetic basis for this variability was explored in a prospective cohort. Methods Physical and psychological health of women were assessed prospectively following therapy for early stage breast cancer with self-report questionnaires. Participation in a genetic association sub-study was offered. Indices for the key symptom domains of fatigue, pain, depression, anxiety, and neurocognitive difficulties were empirically derived by principal components analysis from end-treatment questionnaires, and then applied longitudinally. Genetic associations were sought with functional single nucleotide polymorphisms (SNPs) in pro- and anti-inflammatory cytokine genes - tumour necrosis factor (TNF)-α (−308 GG), interferon (IFN)-ɣ (+874 TA), interleukin (IL)-10 (1082 GA and −592 CA), IL-6 (−174 GC), IL-1β (−511 GA). Results Questionnaire data was available for 210 participants, of whom 111 participated in the genetic sub-study. As expected, symptom domain scores generally improved over several months following treatment completion. Tumour and adjuvant treatment related factors were unassociated with either severity or duration of the individual symptom domains, but severity of symptoms at end-treatment was strongly associated with duration for each domain (all p < 0.05). In multivariable analyses, risk genotypes were independently associated with: fatigue with IL-6 -174 GG/GC and IL-10 -1082 GG; depression and anxiety with IL-10 -1082 AA; neurocognitive disturbance: TNF-α −308 GG; depression IL-1β (all p < 0.05). The identified SNPs also had cumulative effects in prolonging the time to recovery from the associated symptom domain. Conclusions Genetic factors contribute to the severity and duration of common symptom domains after cancer therapy. Common symptoms following breast cancer treatment can be grouped into symptom domains. Symptom domains are useful to describe patterns and trajectories of symptoms following breast cancer treatment. Cytokine gene polymorphisms are associated with the severity and duration of symptom domains following cancer treatment. The symptom severity at final treatment predicts the duration of symptoms.

Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is reported to affect up to 70 % of cancer survivors. Despite evidence that CIPN-related impairments often translate into balance and mobility deficits, the effects on stepping and quality of gait, well-documented risk factors for falls, are unclear. AIMS (i) Establish choice-stepping reaction time (CSRT) performance in survivors with CIPN compared to young and older healthy controls and people with Parkinson's disease; (ii) document walking stability; (iii) investigate relationships between stepping and gait data to objective and patient-reported outcomes. METHODS 41 cancer survivors with CIPN (mean (SD) age: 60.8 (9.7) years) who were ≥3months post chemotherapy, performed tests of simple and inhibitory CSRT. Walking stability measures were derived from 3-D accelerometry data during the 6-minute walk test. CIPN was assessed using neurological grading and patient-reported outcome measures (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire in CIPN Questionnaire scale EORTC CIPN20). RESULTS In both stepping tests, CIPN participants performed at the level of adults aged 10 years older and people with mild to moderate Parkinson's disease. Mean (SD) total stepping response times in both CSRT (1160 (190) milliseconds) and inhibitory CSRT (1191 (164) milliseconds) tests were not associated with objective neurological grading but were correlated with increased difficulty feeling the ground. Participants with lower-limb vibration sensation deficit had slower and more variable CSRT times. There were no associations between walking stability and objective measures of CIPN, and limited correlations with the EORTC-CIPN20. CONCLUSIONS Cancer survivors with CIPN showed deficits in voluntary stepping responses and seemed to compensate for their sensory and motor deficits by walking slower to maintain stability. Objective and patient-reported outcomes of CIPN were correlated with slower and more variable stepping response times. Future studies should aim to identify the causes of the apparent premature decline in cognitive-motor function and develop remediating interventions.

Abstract
AIMS In the current eighth edition head and neck TNM staging, extranodal extension (ENE) is an adverse feature in oral cavity squamous cell cancer (OSCC). The previous seventh edition N1 with ENE is now staged as N2a. Seventh edition N2+ with ENE is staged as N3b in the eighth edition. We evaluated its potential impact on patients treated with surgery and postoperative intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS OSCC patients treated with primary surgery and adjuvant (chemo)radiotherapy between January 2005 and December 2014 were reviewed. Cohorts with pathological node-negative (pN-), pathological node-positive without ENE (pN+_pENE-) and pathological node-positive with ENE (pN+_pENE+) diseases were compared for local control, regional control, distant control and overall survival. The pN+ cohorts were further stratified into seventh edition N-staging subgroups for outcomes comparison. RESULTS In total, 478 patients were evaluated: 173 pN-; 159 pN+_pENE-; 146 pN+_pENE+. Outcomes at 5 years were: local control was identical (78%) in all cohorts (P = 0.892), whereas regional control was 91%, 80% and 68%, respectively (P < 0.001). Distant control was 97%, 87%, 68% (P < 0.001) and overall survival was 75%, 53% and 39% (P < 0.001), respectively. Overall survival for N1 and N2a subgroups was not significantly different. In the seventh edition N2b subgroup of pENE- (n = 79) and pENE+ (n = 79) cohorts, overall survival was 67% and 37%, respectively. In the seventh edition N2c subgroups, overall survival for pENE- (n = 17) and pENE+ (n = 38) cohorts was 65% and 35% (P = 0.08), respectively. Overall, an additional 128 patients (42% pN+) were upstaged as N3b. CONCLUSIONS When eighth edition staging was applied, stage migration across the N2-3 categories resulted in expected larger separations of overall survival by stage. Patients treated with primary radiation without surgical staging should have outcomes carefully monitored. Strategies to predict ENE preoperatively and trials to improve the outcomes of pENE+ patients should be explored.

Abstract
e12596 Background: Triple negative breast cancers (TNBC), characterized by the lack of expression of estrogen receptors and progesterone receptors as well as human epidermal growth factor receptor 2, are associated with high distant recurrence rate and death. As a result, the majority of patients with TNBC are treated with perioperative chemotherapy with the goal of eradicating micrometastases and preventing distrant relapse. The preoperative systemic therapy offers the advantages of permitting an assessment of chemo-sensitivity, increased rates of breast conserving surgery and the ability to adapt postoperative therapies depending on the response. Recently, neoadjuvant chemotherapy has been used at an increasing frequency. The response to neoadjuvant chemotherapy, as measured by the residual cancer burden index, for example, is correlated with the long-term prognosis of TNBC and HER2 expressing breast cancers. Previous studies suggest that tumor-infiltrating lymphocytes (TILs) may correlate with pathological complete response (pCR) rates in TNBC patients treated with neoadjuvant chemotherapy. The pathologic evaluation of TILs in TNBC has been recommended by the International TILs working group since 2014. In this study we sought to analyze the association of TILs with pCR in a cohort of TNBC patients treated with neoadjuvant chemotherapy. Methods: An IRB-approved single-institution retrospective analysis was performed on 127 patients diagnosed with TNBC who received neoadjuvant anthracycline and taxane based chemotherapy at the Ohio State University Comprehensive Cancer Center between January 1st, 2012 and November 31st, 2018. We analyzed TILs as a continuous variable as a part of a secondary analysis of this data. Whole tissue sections from archived H&E stained glass slides were scanned using Philips UltraFast Scanner at ×40 magnification with a single-focus layer. TIL scoring was performed according to guideline recommendations from the International TILs Working Group (2014). Results: A total of 127 female patients with TNBC were identified. The median age at diagnosis was 52.0 years (range 32.0, 74.0) and patients were predominately white (103, 81%), post-menopausal (68, 53.5%) and presented with invasive ductal cancer (113, 89%), stage II (88, 69%), and high grade (108, 85%). Of those patients, 56 had TILs measurement available. pCR was associated with statistically higher level of TILs in core biopsies taken prior to chemotherapy had (Wilcoxon rank-sum test, p = 0.04). Conclusions: The long-term prognosis of patients with TNBC is predicted by the response to neoadjuvant chemotherapy. Consistent with other studies, our study revealed that TILs are associated with a higher probability of pCR. Our future goals are to identify which TIL subsets correlate best with pCR and to identify the mechanism for the increased chemotherapy responsiveness of lymphocyte-infiltrated tumors.
