Abstract
BACKGROUND The risk of incident dementia after surgery in older adults is unclear. The study objective was to examine the rate of incident dementia among older adults after elective surgery compared with a matched nonsurgical control group. METHODS We conducted a population-based, propensity-matched retrospective cohort study using data from linked administrative databases in Ontario, Canada. All community-dwelling individuals aged 66 years and older who underwent one of five major elective surgeries between April 1, 2007 and March 31, 2011 were included. Each surgical patient was matched 1:1 on surgical specialty of the surgeon at consultation, age, sex, fiscal year of entry, and propensity score with a patient who attended an outpatient visit with a surgeon of the same surgical specialty but did not undergo surgery. Patients were followed for up to 5 years after cohort entry for the occurrence of a new dementia diagnosis, defined from administrative data. Cause-specific hazard models were used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for the association between surgery and the hazard of incident dementia. Subgroup and sensitivity analyses were performed. RESULTS A total of 27,878 individuals (13,939 matched pairs) were included in the analysis. A total of 640 (4.6%) individuals in the surgical group and 965 (6.9%) individuals in the control group developed dementia over the 5-year follow-up period. Individuals who underwent surgery had a reduced rate of incident dementia compared with their matched nonsurgical controls (HR 0.88; 95% CI 0.80-0.97; p = 0.01). This association was persistent in most subgroups and after sensitivity analyses. CONCLUSIONS Elective surgery did not increase the rate of incident dementia when compared with matched nonsurgical controls. This could be an important consideration for patients and surgeons when elective surgery is considered.

Abstract
The sheared-flow-stabilized Z pinch concept has been studied extensively and is able to produce fusion-relevant plasma parameters along with neutron production over several microseconds. We present here elevated electron temperature results spatially and temporally coincident with the plasma neutron source. An optical Thomson scattering apparatus designed for the FuZE device measures temperatures in the range of 1-3 keV on the axis of the device, 20 cm downstream of the nose cone. The 17-fiber system measures the radial profiles of the electron temperature. Scanning the laser time with respect to the neutron pulse time over a series of discharges allows the reconstruction of the T_{e} temporal response, confirming that the electron temperature peaks simultaneously with the neutron output, as well as the pinch current and inductive voltage generated within the plasma. Comparison to spectroscopic ion temperature measurements suggests a plasma in thermal equilibrium. The elevated T_{e} confirms the presence of a plasma assembled on axis, and indicates limited radiative losses, demonstrating a basis for scaling this device toward net gain fusion conditions.

Abstract
Importance A publicly funded fertility program was introduced in Ontario, Canada, in 2015 to increase access to fertility treatment. For in vitro fertilization (IVF), the program mandated an elective single-embryo transfer (eSET) policy. However, ovulation induction and intrauterine insemination (OI/IUI)-2 other common forms of fertility treatment-were more difficult to regulate in this manner. Furthermore, prior epidemiologic studies only assessed fetuses at birth and did not account for potential fetal reductions that may have been performed earlier in pregnancy. Objective To examine the association between fertility treatment and the risk of multifetal pregnancy in a publicly funded fertility program, accounting for both fetal reductions and all live births and stillbirths. Design, Setting, and Participants This population-based, retrospective cohort study used linked administrative health databases at ICES to examine all births and fetal reductions in Ontario, Canada, from April 1, 2006, to March 31, 2021. Exposure Mode of conception: (1) unassisted conception, (2) OI/IUI, or (3) IVF. Main Outcomes and Measures The main outcome was multifetal pregnancy (ie, a twin or higher-order pregnancy). Modified Poisson regression generated adjusted relative risks (ARRs) and derived population attributable fractions (PAFs) for multifetal pregnancies attributable to fertility treatment. Absolute rate differences (ARDs) were used to compare the era before eSET was promoted (2006-2011) with the era after the introduction of the eSET mandate (2016-2021). Results Of all 1 724 899 pregnancies, 1 670 825 (96.9%) were by unassisted conception (mean [SD] maternal age, 30.6 [5.2] years), 24 395 (1.4%) by OI/IUI (mean [SD] maternal age, 33.1 [4.4] years), and 29 679 (1.7%) by IVF (mean [SD] maternal age, 35.8 [4.7] years). In contrast to unassisted conception, individuals who received OI/IUI or IVF tended to be older, reside in a high-income quintile neighborhood, or have preexisting health conditions. Multifetal pregnancy rates were 1.4% (95% CI, 1.4%-1.4%) for unassisted conception, 10.5% (95% CI, 10.2%-10.9%) after OI/IUI, and 15.5% (95% CI, 15.1%-15.9%) after IVF. Compared with unassisted conception, the ARR of any multifetal pregnancy was 7.0 (95% CI, 6.7-7.3) after OI/IUI and 9.9 (95% CI, 9.6-10.3) after IVF, with corresponding PAFs of 7.1% (95% CI, 7.1%-7.2%) and 13.4% (95% CI, 13.3%-13.4%). Between the eras of 2006 to 2011 and 2016 to 2021, multifetal pregnancy rates decreased from 12.9% to 9.1% with OI/IUI (ARD, -3.8%; 95% CI, -4.2% to -3.4%) and from 29.4% to 7.1% with IVF (ARD, -22.3%; 95% CI, -23.2% to -21.6%). Conclusions and Relevance In this cohort study of more than 1.7 million pregnancies in Ontario, Canada, a publicly funded IVF program mandating an eSET policy was associated with a reduction in multifetal pregnancy rates. Nevertheless, ongoing strategies are needed to decrease multifetal pregnancy, especially in those undergoing OI/IUI.

Abstract
Importance Patients with stage IV non-small cell lung cancer (NSCLC) experience substantial morbidity and mortality. Contact days (ie, the number of days with health care contact outside the home) measure how much of a person's life is consumed by health care, yet little is known about patterns of contact days for patients with NSCLC. Objective To describe the trajectories of contact days in patients with stage IV NSCLC and how trajectories vary by receipt of cancer-directed treatment in routine practice. Design, Setting, and Participants A retrospective, population-based decedent cohort study was conducted in Ontario, Canada. Participants included adults aged 20 years or older who were diagnosed with stage IV NSCLC (January 1, 2014, to December 31, 2017) and died (January 1, 2014, to December 31, 2019); there was a maximum 2-year follow-up. Data analysis was conducted from February 22 to August 16, 2023. Exposure Systemic cancer-directed therapy (yes or no) and type of therapy (chemotherapy vs immunotherapy vs targeted therapy). Main Outcomes and Measures Contact days (days with health care contact, outpatient or institution-based, outside the home) were identified through administrative data. The weekly percentage of contact days and fitted models with cubic splines were quantified to describe trajectories from diagnosis until death. Results A total of 5785 decedents with stage IV NSCLC were included (median age, 70 [IQR 62-77] years; 3108 [53.7%] were male, and 1985 [34.3%] received systemic therapy). The median overall survival was 108 (IQR, 49-426) days, median contact days were 36 (IQR, 21-62), and the median percentage that were contact days was 33.3%. A median of 5 (IQR, 2-10) days were spent with specialty palliative care. Patients who did not receive systemic therapy had a median overall survival of 66 (IQR, 34-130) days and median contact days of 28 (IQR, 17-44), of which a median of 5 (IQR, 2-9) days were spent with specialty palliative care. Overall and for subgroups, normalized trajectories followed a U-shaped distribution: contact days were most frequent immediately after diagnosis and before death. Patients who received targeted therapy had the lowest contact day rate during the trough (10.6%; vs immunotherapy, 15.4%; vs chemotherapy, 17.7%). Conclusions and Relevance In this cohort study, decedents with stage IV NSCLC had a median survival in the order of 3.5 months and spent 1 in every 3 days alive interacting with the health care system outside the home. These results highlight the need to better support patients and care partners, benchmark appropriateness, and improve care delivery.

Abstract
BACKGROUND We sought to describe patterns of delivery of adjuvant (aRT) and salvage RT (sRT) in patients who underwent RP after receiving neoadjuvant androgen receptor pathway inhibitor (ARPI) before radical prostatectomy (RP) for high-risk localized prostate cancer (HRLPC). METHODS Two hundred eighteen patients treated on phase 2 neoadjuvant trials between 2006 and 2018 at two academic centers were evaluated. aRT and sRT were defined as receipt of RT with a PSA of ≤0.1 or >0.1 ng/mL, respectively. Primary outcomes were biochemical recurrence (BCR), defined as time from aRT/sRT to a PSA rising to >0.1 ng/mL, and metastasis-free survival (MFS) after RT. RESULTS Twenty-three (11%) and 55 (25%) patients received aRT and sRT respectively. Median PSA at start of aRT and sRT was 0.01 and 0.16 ng/mL, and median duration from RP to RT was 5 and 14 months, respectively. All aRT patients had NCCN high-risk disease, 30% were pN1 and 43% had positive surgical margins; 52% had prostate bed RT. Fifty-one percent of sRT patients had biopsy Gleason 9-10, 29% were pT2 and 9% had positive surgical margins; 63% had RT to the prostate bed/pelvis. At a median follow-up of 5.3 and 3.0 years after aRT and sRT, 3-year freedom from BCR was 55% and 47%, and 3-year MFS was 56% and 53%, respectively. CONCLUSIONS aRT was infrequently used in patients who received neoadjuvant ARPI before RP for HRLPC. Outcomes of aRT and sRT were similar but generally poor. Studies evaluating intensified systemic therapy approaches with postoperative RT in this high-risk population are needed.

Abstract
Background To date, economic analyses of tissue-based next generation sequencing genomic profiling (NGS) for advanced solid tumors have typically required models with assumptions, with little real-world evidence on overall survival (OS), clinical trial enrollment or end-of-life quality of care. Methods Cost consequence analysis of NGS testing (555 or 161-gene panels) for advanced solid tumors through the OCTANE clinical trial (NCT02906943). This is a longitudinal, propensity score-matched retrospective cohort study in Ontario, Canada using linked administrative data. Patients enrolled in OCTANE at Princess Margaret Cancer Centre from August 2016 until March 2019 were matched with contemporary patients without large gene panel testing from across Ontario not enrolled in OCTANE. Patients were matched according to 19 patient, disease and treatment variables. Full 2-year follow-up data was available. Sensitivity analyses considered alternative matched cohorts. Main Outcomes were mean per capita costs (2019 Canadian dollars) from a public payer's perspective, OS, clinical trial enrollment and end-of-life quality metrics. Findings There were 782 OCTANE patients with 782 matched controls. Variables were balanced after matching (standardized difference <0.10). There were higher mean health-care costs with OCTANE ($79,702 vs. $59,550), mainly due to outpatient and specialist visits. Publicly funded drug costs were less with OCTANE ($20,015 vs. $24,465). OCTANE enrollment was not associated with improved OS (restricted mean survival time [standard error]: 1.50 (±0.03) vs. 1.44 (±0.03) years, log-rank p = 0.153), varying by tumor type. In five tumor types with ≥35 OCTANE patients, OS was similar in three (breast, colon, uterus, all p > 0.40), and greater in two (ovary, biliary, both p < 0.05). OCTANE was associated with greater clinical trial enrollment (25.4% vs. 9.5%, p < 0.001) and better end-of-life quality due to less death in hospital (10.2% vs. 16.4%, p = 0.003). Results were robust in sensitivity analysis. Interpretation We found an increase in healthcare costs associated with multi-gene panel testing for advanced cancer treatment. The impact on OS was not significant, but varied across tumor types. OCTANE was associated with greater trial enrollment, lower publicly funded drug costs and fewer in-hospital deaths suggesting important considerations in determining the value of NGS panel testing for advanced cancers. Funding T.P H holds a research grant provided by the Ontario Institute for Cancer Research through funding provided by the Government of Ontario (#IA-035 and P.HSR.158) and through funding of the Canadian Network for Learning Healthcare Systems and Cost-Effective 'Omics Innovation (CLEO) via Genome Canada (G05CHS).

Abstract
BACKGROUND AND AIM Cytomegalovirus (CMV) colitis is associated with negative outcomes in inflammatory bowel disease (IBD) and immunosuppressed cohorts and therefore requires timely recognition for appropriate management. We aimed to evaluate the diagnostic tools for CMV colitis and their associations with clinical outcomes. METHODS A retrospective cohort study of patients in a metropolitan health service with colonic samples analysed for CMV between 2012 and 2022, stratified into IBD and non-IBD groups, was performed. The main outcome measures were the prevalence of positive and negative results for each CMV test, as well as need for colectomy, use of antiviral and hospital length of stay. RESULTS Five hundred eighty-two biopsies from 418 patients were included; the median age was 36 years (interquartile range, 24-52 years) and 223 (53.3%) were men. Four hundred sixty-one (79.2%) biopsies were from patients with IBD and 121 (20.8%) were from those without IBD. There were similar proportions of positive CMV histology (IBD 5.9% and non-IBD 7.4%) and tissue CMV polymerase chain reaction (PCR) in the two groups (IBD 5.6% and non-IBD 5.0%), but within each group, results were discordant. Positive CMV histology was significantly associated with need for colectomy in the IBD group, while positive tissue CMV PCR was not. Positive CMV histology, and tissue and serum CMV PCR were all significantly associated with antiviral use. Positive serum CMV PCR was significantly associated with colectomy. CONCLUSIONS Histopathology remains the most predictive tool in assessing CMV colitis, while qualitative tissue CMV PCR was found to have limited utility. Quantitative serum CMV PCR may be useful but requires further evaluation.

Abstract
Stereotactic magnetic resonance (MR)-guided adaptive radiotherapy (SMART) for renal cell carcinoma may result in more precise treatment delivery through the capabilities for improved image quality, daily adaptive planning, and accounting for respiratory motion during treatment with real-time MR tracking. In this study, we aimed to characterize the safety and feasibility of SMART for localized kidney cancer. Twenty patients with localized kidney cancer (ten treated in a prospective phase 1 trial and ten in the supplemental cohort) were treated to 40 Gy in five fractions on a 0.35 T MR-guided linear accelerator with daily adaptive planning and a cine MR-guided inspiratory breath hold technique. The median follow-up time was 17 mo (interquartile range: 13-20 months). A single patient developed local failure at 30 mo. No grade ≥3 adverse events were reported. The mean decrease in estimated glomerular filtration rate was -1.8 ml/min/1.73 m2 (95% confidence interval or CI [-6.6 to 3.1 ml/min/1.73 m2]), and the mean decrease in tumor diameter was -0.20 cm (95% CI [-0.6 to 0.2 cm]) at the last follow-up. Anterior location and overlap of the 25 or 28 Gy isodose line with gastrointestinal organs at risk were predictive of the benefit from online adaptive planning. Kidney SMART is feasible and, at the early time point evaluated in this study, was well tolerated with minimal decline in renal function. More studies are warranted to further evaluate the safety and efficacy of this technique. PATIENT SUMMARY: For patients with localized renal cell carcinoma who are not surgical candidates, stereotactic magnetic resonance--guided adaptive radiotherapy is a feasible and safe noninvasive treatment option that results in minimal impact on kidney function.

Abstract
BACKGROUND Protracted times to diagnosis of cancer can lead to increased patient anxiety, and in some cases, disease progression and worse outcomes. This study assessed the time to diagnosis for melanoma, and its variability, according to patient-, disease-, and system-level factors. METHODS This is a descriptive, cross-sectional study in Ontario, Canada from 2007-2019. We used administrative health data to measure the diagnostic interval (DI)-and its two subintervals-the primary care subinterval (PCI) and specialist care subinterval (SCI). Multivariable quantile regression was used. RESULTS There were 33,371 melanoma patients. The median DI was 36 days (interquartile range [IQR]: 8-85 days), median PCI 22 days (IQR: 6-54 days), and median SCI 6 days (IQR: 1-42 days). Increasing comorbidity was associated with increasing DI. Residents in the most deprived neighbourhoods and those in rural areas experienced shorter DIs and PCIs, but no differences in SCI. There was substantial variation in the DI and SCI across health regions, but limited differences in the PCI. Finally, patients with a history of non-melanoma skin cancer, and those previously established with a dermatologist experienced significantly longer DI, PCI, and SCI. DISCUSSION This study found variability in the melanoma DI, notably by system-level factors.

Abstract
BACKGROUND Hearing loss is one of the most common sensory impairments and hearing aids are the most common unmet assistive device need among individuals with a disability. The benefits of hearing interventions are well-documented as they are known to deter the sequalae of hearing loss including social isolation, poor mental health, falls and cognitive decline. Identifying trends in hearing aid users can provide valuable information for improving access to hearing loss interventions. METHODS Data were retrieved from ICES databases that were used to generate a cohort of 372,448 individuals in Ontario, Canada, who first claimed hearing aids between April 2007 and March 2018 through the Assistive Devices Program. RESULTS The data indicated that the frequency distribution of hearing aids has steadily inclined since 2007. The mean age of hearing aid users was 70.25 ± 14.70 years and higher neighbourhood income quintile was associated with greater hearing aid use (p < 0.001). Most first claims occurred after visiting primary care physicians (70.60%) compared with otolaryngology (13.39%). An examination of clinical comorbidities revealed hypertension (63.41%), and diabetes (24.93%) to be the most common. Regression analysis demonstrated a positive associated between age and most comorbidities. Furthermore, higher neighbourhood income quintiles were associated with a reduced risk of having the examined comorbidities. CONCLUSIONS This study examines patient demographics and clinical comorbidities in a cohort of hearing aid users in Ontario. The results identify associations between demographics and comorbidities that provide information relevant for improving access to hearing interventions and clinical decision-making in primary care.Implications for RehabilitationScreening for hearing loss (using an audiogram) in elderly individuals that manage multiple comorbidities, and any patient with significant risk factors for hearing loss (e.g., noise exposure history, prior ototoxic medications, prior head injury, history of ear surgery, family history of hearing loss) will identify deficits and direct appropriate hearing interventions.Improving access to care in low-income communities should include community-based education around expectation management and communication strategies to reinforce proper use and care of hearing devices.Geographic proximity to hearing testing facilities and hearing aid dispensaries is a significant barrier to hearing rehabilitation strategies.

Abstract
INTRODUCTION The prevalence of hearing loss in Canada is high, with many patients requiring implantable hearing devices (IHDs) as treatment for their disease severity. Despite this need, many eligible patients do not pursue these interventions. The objective of this study was to examine rates of IHD based on geographic location to understand locoregional variation in access to care. STUDY DESIGN This was a retrospective population-based cohort study. SETTING All hospitals in the Canadian province of Ontario. METHODS Of all patients with IHD between April 1, 1992, and March 31, 2021, cochlear implants (CIs) (4,720) and bone-anchored hearing aids (BAHA) (1,125) cohorts were constructed. Place of residence was categorized based on Local Health Integrated Network (LHIN). Summary statistics for place of surgical institution based on LHIN at first surgery, name of institution of first surgery and "as the crow flies" distance (in km) between place of residence and surgical institution were calculated. Rate of implantations was calculated for LHIN regions based on number of surgeries per 1,000,000 persons/years. RESULTS Toronto Central, Central, Central East, and Champlain regions had >10% of patients undergoing BAHA and CI. 1,019 (90.6%) and 4,232 (89.7%) of patients receiving BAHA and CI, respectively, resided in urban/suburban regions and 94 patients (8.4%) and 436 (9.2%) resided in rural regions. The median distance between residential location and the institution was 46.4 km (interquartile range [IQR], 18.9-103.6) and 44.7 km (IQR, 15.7-96.9) for BAHA and CI, respectively. From 1992 to 2021, the number of CI and BAHA performed across Ontario increased by 17 folds and 6 folds, respectively. CONCLUSION This large comprehensive population study provides longitudinal insight into the access to care of IHD based on geographic factors. Our findings of the present population-based study indicate an overall increase in access to devices with disproportionate access to care based on geographic locations. Further work is needed to characterize barriers to IHD access to align with demands.

Abstract
Importance Melanoma treatment has evolved during the past decade with the adoption of adjuvant and palliative immunotherapy and targeted therapies, with an unclear impact on health care costs and outcomes in routine practice. Objective To examine changes in health care costs, overall survival (OS), and time toxicity associated with primary treatment of melanoma. Design, Setting, and Participants This cohort study assessed a longitudinal, propensity score (PS)-matched, retrospective cohort of residents of Ontario, Canada, aged 20 years or older with stages II to IV cutaneous melanoma identified from the Ontario Cancer Registry from January 1, 2018, to March 31, 2019. A historical comparison cohort was identified from a population-based sample of invasive melanoma cases diagnosed from the Ontario Cancer Registry from January 1, 2007, to December 31, 2012. Data analysis was performed from October 17, 2022, to March 13, 2023. Exposures Era of melanoma diagnosis (2007-2012 vs 2018-2019). Main Outcomes and Measures The primary outcomes were mean per-capita health care and systemic therapy costs (Canadian dollars) during the first year after melanoma diagnosis, time toxicity (days with physical health care contact) within 1 year of initial treatment, and OS. Standardized differences were used to compare costs and time toxicity. Kaplan-Meier methods and Cox proportional hazards regression were used to compare OS among PS-matched cohorts. Results A PS-matched cohort of 731 patients (mean [SD] age, 67.9 [14.8] years; 437 [59.8%] male) with melanoma from 2018 to 2019 and 731 patients (mean [SD] age, 67.9 [14.4] years; 440 [60.2%] male) from 2007 to 2012 were evaluated. The 2018 to 2019 patients had greater mean (SD) health care (including systemic therapy) costs compared with the 2007 to 2012 patients ($47 886 [$55 176] vs $33 347 [$31 576]), specifically for stage III ($67 108 [$57 226] vs $46 511 [$30 622]) and stage IV disease ($117 450 [$79 272] vs $47 739 [$37 652]). Mean (SD) systemic therapy costs were greater among 2018 to 2019 patients: stage II ($40 823 [$40 621] vs $10 309 [$12 176]), III ($55 699 [$41 181] vs $9764 [$12 771]), and IV disease ($79 358 [$50 442] vs $9318 [$14 986]). Overall survival was greater for the 2018 to 2019 cohort compared with the 2007 to 2012 cohort (3-year OS: 74.2% [95% CI, 70.8%-77.2%] vs 65.8% [95% CI, 62.2%-69.1%], hazard ratio, 0.72 [95% CI, 0.61-0.85]; P < .001). Time toxicity was similar between eras. Patients with stage IV disease spent more than 1 day per week (>52 days) with physical contact with the health care system by 2018 to 2019 (mean [SD], 58.7 [43.8] vs 44.2 [26.5] days; standardized difference, 0.40; P = .20). Conclusions and Relevance This cohort study found greater health care costs in the treatment of stages II to IV melanoma and substantial time toxicity for patients with stage IV disease, with improvements in OS associated with the adoption of immunotherapy and targeted therapies. These health system-wide data highlight the trade-off with adoption of new therapies, for which there is a greater economic burden to the health care system and time burden to patients but an associated improvement in survival.

Abstract
OBJECTIVE Dynamin-related protein 1 (Drp1) is the key regulator of mitochondrial fission. We and others have reported a strong correlation between enhanced Drp1 activity and impaired skeletal muscle insulin sensitivity. This study aimed to determine whether Drp1 directly regulates skeletal muscle insulin sensitivity and whole-body glucose homeostasis. METHODS We employed tamoxifen-inducible skeletal muscle-specific heterozygous Drp1 knockout mice (mDrp1+/-). Male mDrp1+/- and wildtype (WT) mice were fed with either a high-fat diet (HFD) or low-fat diet (LFD) for four weeks, followed by tamoxifen injections for five consecutive days, and remained on their respective diet for another four weeks. In addition, we used primary human skeletal muscle cells (HSkMC) from lean, insulin-sensitive, and severely obese, insulin-resistant humans and transfected the cells with either a Drp1 shRNA (shDrp1) or scramble shRNA construct. Skeletal muscle and whole-body insulin sensitivity, skeletal muscle insulin signaling, mitochondrial network morphology, respiration, and H2O2 production were measured. RESULTS Partial deletion of the Drp1 gene in skeletal muscle led to improved whole-body glucose tolerance and insulin sensitivity (P < 0.05) in diet-induced obese, insulin-resistant mice but not in lean mice. Analyses of mitochondrial structure and function revealed that the partial deletion of the Drp1 gene restored mitochondrial dynamics, improved mitochondrial morphology, and reduced mitochondrial Complex I- and II-derived H2O2 (P < 0.05) under the condition of diet-induced obesity. In addition, partial deletion of Drp1 in skeletal muscle resulted in elevated circulating FGF21 (P < 0.05) and in a trend towards increase of FGF21 expression in skeletal muscle tissue (P = 0.095). In primary myotubes derived from severely obese, insulin-resistant humans, ShRNA-induced-knockdown of Drp1 resulted in enhanced insulin signaling, insulin-stimulated glucose uptake and reduced cellular reactive oxygen species (ROS) content compared to the shScramble-treated myotubes from the same donors (P < 0.05). CONCLUSION These data demonstrate that partial loss of skeletal muscle-specific Drp1 expression is sufficient to improve whole-body glucose homeostasis and insulin sensitivity under obese, insulin-resistant conditions, which may be, at least in part, due to reduced mitochondrial H2O2 production. In addition, our findings revealed divergent effects of Drp1 on whole-body metabolism under lean healthy or obese insulin-resistant conditions in mice.

Abstract
Importance A shorter time interval to prostate-specific antigen (PSA) failure is associated with worse clinical outcomes; however, specific factors defining this state remain unknown. Objective To evaluate the factors of a short time interval to PSA failure in order to identify patients for treatment escalation randomized clinical trials. Design, Setting, and Participants This secondary analysis of a randomized clinical trial was a secondary analysis of the Dana-Farber Cancer Institute 05-043 trial and included 350 patients with nonmetastatic unfavorable risk prostate cancer (PC). Interventions Patients were randomized 1:1 to receive androgen deprivation therapy (ADT) and radiation therapy (RT) plus docetaxel vs ADT and RT. Main Outcomes and Measures Cumulative incidence rates curves of PSA failure, defined as PSA nadir plus 2 ng/mL or initiation of salvage therapies, and the Fine and Gray competing risks regression was used to assess the prognostic association between these factors and time to PSA failure. Results The study included 350 males who primarily had a good performance status (330 [94.3%] with Eastern Cooperative Oncology Group score of 0), median (range) age of 66 (43-86) years, with 167 (46.6%) having Gleason scores of 8 to 10, and 195 (55.2%) presenting with a baseline PSA of more than 10 ng/mL. After a median (IQR) follow-up of 10.2 (8.0-11.4) years, having a PSA level of 10 ng/mL to 20 ng/mL (subdistribution hazard ratio [sHR], 1.98; 95% CI, 1.28-3.07; P = .002) and a Gleason score of 8 to 10 (sHR, 2.55; 95% CI, 1.63-3.99; P < .001) were associated with a shorter time to PSA failure, and older age (sHR, 0.82; 95% CI, 0.72-0.93; P = .002) was associated with reduced risk for PSA failure after adjusting for other baseline clinical factors. The high-risk category, defined by these 3 factors, was associated with a shorter time to PSA failure (sHR, 2.69; 95% CI, 1.84-3.93; P < .001). Conclusions and Relevance In this secondary analysis of a randomized clinical trial of males with unfavorable risk PC, young age, PSA of 10 ng/mL or more, and a Gleason score of 8 to 10 estimated a shorter time to PSA failure. A subgroup of males at very high-risk for early PSA failure, as defined by our study, may benefit from treatment escalation with androgen receptor signaling inhibitors or cytotoxic chemotherapy and should be the subject of a prospective randomized clinical trial. Trial Registration NCT00116142.

Abstract
PURPOSE/OBJECTIVE(S) The SEISMIC trial aims to find the best method for mediastinal staging in patients with lung cancer receiving chemoradiotherapy. Currently, CT or PET-CT scans are standard in clinical practice, but histological evaluation of the mediastinum is performed on a case-by-case basis. The study will examine the effect of systematic histological evaluation using Endobronchial Ultrasound (EBUS) on radiotherapy target volumes. The hypothesis of this study is that differences in staging between the diagnostic PET-CT and EBUS would result in reduced tumor coverage and/or increased doses to organs at risk (OAR). MATERIALS/METHODS SEISMIC is a prospective multicenter international cohort study. Patients were enrolled from Australia, the Netherlands, USA and Canada after regional IRB approvals. Patients were treated with 4DCT simulation. Two iGTV and PTV target volumes were delineated for each patient with discordant staging according to both PET-CT and EBUS, as were OARs. Two VMAT plans were generated for each patient based on either PET-CT or EBUS target volumes using knowledge-based planning methodology. Plans aimed to achieve institutional guidelines for target coverage and OAR dose constraints, with a prescribed dose of 60 Gy in 30 fractions. Target coverage and OAR doses for the PET- and EBUS-defined volumes were compared. RESULTS In 156 patients, EBUS showed a larger extent of disease than PET in 18 (11.5%) and a smaller extent of lymph node (LN) involvement than PET in 49 (31.4%). Out of 67 patients with PET-EBUS discordant results, 25 underwent upfront radiotherapy and were included in the study. EBUS revealed PET-occult LN involvement in 11/25 patients (44%). In these patients, 10/11 patients received <95% of the prescribed dose to PET-occult LN iGTVs; the median [range] minimum dose to the EBUS iGTV was 9.2 Gy [0.1 - 57.9 Gy]. When planning based on EBUS LN involvement, all patients received ≥95% of the prescribed dose to the iGTV (the median [range] minimum dose to the EBUS iGTV was 58.9 Gy [58.1 - 60.5 Gy]). This resulted in increased median [range] doses to OARs; mean lung dose increased by 1.1 Gy [0.3 - 8.4 Gy], esophagus mean dose increased by 3.6 Gy [0.2 - 24.8 Gy], and mean heart dose increased by 0.5 Gy [-0.6 - 8.5 Gy]. CONCLUSION Systematic endoscopic evaluation of the mediastinum had a significant effect on tumor coverage in a clinically meaningful proportion of cases and consequent plan adaptation impacted on organ-at-risk (OAR) doses. Results suggest systematic mediastinal LN staging should be considered in all patients prior to curative-intent radiotherapy. CLINICAL TRIAL ID ACTRN12617000333314.

Abstract
The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in the Journal of Clinical Oncology, to patients seen in their own clinical practice.For generations, oncologists and urologists have used androgen deprivation therapy (ADT) to manage metastatic hormone-sensitive prostate cancer (mHSPC). Until recently, ADT monotherapy was standard. Within the past decade, a series of trials have clearly demonstrated improved outcomes with a more aggressive up-front approach. Doublet intensification therapy, involving either ADT plus docetaxel or ADT plus any of several second-generation oral androgen-receptor pathway inhibitors (ARPIs), provide considerable survival advantages compared with ADT alone. In 2022, two trials, PEACE-1 and ARASENS, demonstrated the potential of triplet therapy, adding an ARPI to an ADT-docetaxel doublet. In the Original Report that accompanies this article, the authors provide a post hoc analysis of ARASENS (ADT plus docetaxel, with or without darolutamide), identifying the subpopulations of patients with mHSPC who might benefit most from a triplet regimen. They segment the ARASENS cohort by disease volume and disease risk profile, finding that triplet therapy is associated with improved outcomes regardless of category (although with limited power in the low-volume cohort). Meanwhile, trials are ongoing examining the role of radiotherapy (RT) in mHSPC, a modality previously reserved for localized disease or isolated, symptomatic metastases. Here, we present a mHSPC case and discuss our approach to mHSPC considering recent studies. We recommend triplet therapy for patients who are suitable candidates for chemotherapy, especially for patients with high-volume disease. We also favor aggressive use of RT, when feasible, for patients with low-volume mHSPC.

Abstract
INTRODUCTION Hearing loss (HL) is considered a potentially modifiable risk factor for dementia. We aimed to examine the relationship between HL and incident dementia diagnosis in a province-wide population-based cohort study with matched controls. METHODS Administrative healthcare databases were linked to generate a cohort of patients who were aged ≥40 years at their first claimed hearing amplification devices (HAD) between April 2007 and March 2016 through the Assistive Devices Program (ADP) (257,285 with claims and 1,005,010 controls). The main outcome was incident dementia diagnosis, ascertained using validated algorithms. Dementia incidence was compared between cases and controls using Cox regression. Patient, disease and other risk factors were examined. RESULTS Dementia incidence rates (per 1,000 person-years) were 19.51 (95% Confidence Interval [CI] 19.26-19.77) and 14.15 (95% CI 14.04-14.26) for the ADP-claimants and matched controls, respectively. In adjusted analyses, risk of dementia was higher in ADP-claimants compared with controls (Hazard Ratio [HR] 1.10 [95% CI 1.09-1.12, p<0.001]). Subgroup analyses showed a dose-response gradient, with risk of dementia higher amongst patients with bilateral HADs (HR 1.12 [95% CI 1.10-1.14, p<0.001]), and an exposure-response gradient, with increasing risk over time from April 2007-March 2010 (HR 1.03 [95% CI 1.01-1.06, p=0.014]), April 2010-March 2013 (HR 1.12 [95% CI 1.09-1.15, p<0.001]) and April 2013-March 2016 (HR 1.19 [95% CI 1.16-1.23, p<0.001]). CONCLUSION In this population-based study, adults with HL had an increased risk of being diagnosed with dementia. Given the implications of HL on dementia risk, understanding the effect of hearing interventions merits further investigation.

Abstract
IntroductionPopulation-based datasets are often used to estimate changes in utilization or outcomes of novel therapies. Inclusion or exclusion of unstaged patients may impact on interpretation of these studies.MethodsA large population-based dataset in Ontario, Canada of non-small cell lung cancer patients was examined to evaluate the characteristics and outcomes of unstaged patients compared to staged patients. Multivariable Poisson regression was used to evaluate differences in patient-level characteristics between groups. Kaplan-Meier estimates of survival and log-rank statistics were utilized.ResultsIn our Ontario cohort of 51,152 patients with NSCLC, 11.2% (n=5,707) were unstaged, and there was evidence that stage data was not missing completely at random. Those without assigned stage were more likely than staged patients to be older (RR [95%CI]), (70-79 vs. 20-59: 1.51 [1.38-1.66]; 80+ vs. 20-59: 2.87 [2.62-3.15]), have a higher comorbidity index (Score 1-2 vs 0: 1.19 [1.12-1.27]; 3 vs. 0: 1.49 [1.38-1.60]), and have a lower socioeconomic class (4 vs. 1 (lowest): 0.91 [0.84-0.98]; 5 vs. 1 (lowest): 0.89 [0.83-0.97]). Overall survival of unstaged patients suggested a mixture of early and advanced stage, but with a large proportion that are probably stage IV patients with more rapid death than those with reported stage IV disease.ConclusionIn this case study, evaluation of stage-specific health care utilization and outcomes for staged patients with stage IV disease at the population level may have a bias as a distinct subset of stage IV patients with rapid death are likely among those without a documented stage in administrative data.

Abstract
OBJECTIVES Infection with COVID-19 presents known and unknown perioperative risks to the patient and operative staff. Pre-operative testing protocols have become widespread, yet little is known about the utility of this practice in asymptomatic patients undergoing elective surgery. We describe the impact and cost of a routine testing protocol on elective surgical procedures in a retrospective series at a single institution. METHODS Standardized pre-operative COVID-19 testing in all surgical patients was implemented in May 2020. Health system protocol required testing 3 to 5 days before all elective surgery. Data stratified by surgical specialty were collected over the initial 90-day period and disposition over a period of 6-months was assessed for all positive and indeterminate results. RESULTS Thirty-one (0.41%) positive results amongst 7579 pre-procedural tests, including 3 of 792 (0.38%) for urologic procedures, were noted in asymptomatic patients. Following a positive test, 20 procedures (62.5%) were delayed an average of 49 days, 8 were not performed and 3 proceeded without delay. All 3 urologic procedures were delayed a mean of 59 days. Institutional cost per test ranged from $34-$54. The number needed to test for one positive result was 244 with a cost of $11,573 for each positive result. CONCLUSIONS Institution of a universal pre-operative COVID-19 screening protocol for asymptomatic, unvaccinated patients undergoing elective surgery identified clinically silent infection in 0.4% of cases with a significant associated cost. Risk and symptom-based testing is likely a better strategy for triaging resources.

Abstract
Hepatoid adenocarcinoma (HAC) is a rare malignancy that may mimic hepatocellular carcinoma (HCC) given its hepatoid histologic appearance and production of alpha fetoprotein. Clinical management and prognosis of HAC varies considerably from HCC. We present two cases of metastatic HAC in a cirrhotic liver diagnosed after biopsy and histopathological evaluation. The cases underscore the importance of recognizing the limitations of diagnostic imaging and pursuing a biopsy where there is diagnostic uncertainty.

Abstract
ObjectivesMelanoma treatment has evolved over the past decade with the adoption of adjuvant and palliative immunotherapies and targeted therapies and changes in use of sentinel node biopsy. The impact on real-world healthcare costs and outcomes is uncertain. Here we examine changes in healthcare costs and survival using administrative data.
ApproachUsing data from the universal healthcare system in Ontario, Canada, we examine a propensity-matched, retrospective cohort of patients aged 20+ years with Stage I-IV invasive cutaneous melanoma from 2018-2019 compared with those from 2007-2012. The primary outcomes were public payer’s mean healthcare per-person costs, and overall survival (OS). Costs were estimated with an established case-mix and claim-based costing algorithm for Ontario, in which person-level costs are allocated for the various healthcare utilizations over time. Standardized mean differences were used to compare costs, and the log-rank test and Cox regression were used to compare survival among stage-stratified, propensity-score matched cohorts.
ResultsWe identified 1,138 patients with melanoma from 2018-2019 and 7,654 from 2007-2012. After stage stratification and propensity-matching (N=1,101 per cohort), sentinel lymph node biopsy (62.3% vs. 43.4%) and systemic therapy use (27.3% vs. 12.5%) were more frequent in 2018-2019 compared to 2007-2012. 2018-2019 patients had greater mean healthcare (including systemic therapy) costs compared to 2007-2012 with Stage II ($27,835 vs. $21,179), III ($90,508 vs. $46,242) and IV disease ($118,398 vs. $46,500). There was a seven-to-twelve-fold increase in mean systemic therapy costs for treated patients with Stage III ($68,207 vs. $9,832) and IV disease ($80,905 vs. $6,883). OS was greater in 2018-2019 versus 2007-2012 (2-year OS: 87.8% [95% Confidence Interval {CI}: 85.8-89.6%] vs. 83.7% [95% CI: 81.3-85.7%]; Hazard Ratio {HR}: 0.72 [95% CI: 0.59-0.89]; p<0.05).
ConclusionThese real-world data highlight trade-offs with adoption of new effective systemic therapies for melanoma, with a greater economic burden to the healthcare system but an associated improvement in survival. Such evolving paradigm changes may prompt dynamic evaluations of healthcare resources and policies to ensure cancer care is sustainable.

Abstract
ObjectivesThe COVID-19 pandemic has been unprecedented and led to drastic reductions in nonurgent medical visits. Deferral of these visits may have critical health impact, including delayed diagnosis for melanoma and other skin cancers. We examined the influence of the pandemic on skin biopsy rates in a large population-based cohort.
ApproachUsing the universal health care claims dataset from Ontario, Canada, we examined skin biopsies from January 6, 2020 to September 27, 2020, and compared these to the same period for 2019. Those diagnosed with anogenital cancers, younger than 20 years, residing out-of-province and with lapses in coverage were excluded. The sensitivity and specificity of claims diagnoses were evaluated with a validated algorithm that identifies keratinocyte carcinoma (KC) in Ontario, and the Ontario Cancer Registry for melanoma cancer. Factors associated with biopsy during the early pandemic were investigated with modified Poisson regression.
ResultsA precipitous drop in total skin biopsies (down to 15% of expected), biopsies for KC (18%) and melanoma (27%) was seen with the onset of COVID-19 cases (p<0.01). Claims diagnoses were of high specificity for KC (99%), and for melanoma (98%), though sensitivity was less (61% and 28%, respectively). In adjusted analysis, the elderly (80+ years), females and residents of certain regions were less likely to be biopsied during the pandemic. Subsequently, there were substantial improvements in biopsy rates over 10 weeks. However, compared to 2019, a large backlog of expected cases still remained 28 weeks after lockdown (45,710 all biopsy, 9,104 KC and 595 melanoma).
ConclusionA drastic reduction in skin biopsies is noted early in the COVID-19 pandemic; this disproportionately affected the elderly, females and certain geographic regions. Though biopsies subsequently increased, a large backlog of cases remained after almost half a year. This will have implications for downstream care of skin cancer.

Abstract
Objective Timely cancer treatment improves survival and anxiety for some sites. Patients with esophageal cancer require specific workup before treatment, which can prolong the time from diagnosis to treatment (treatment interval [TI]). The geographical variation of this interval remains uninvestigated in patients with esophageal cancer. Methods This retrospective population-level study conducted in Ontario used linked administrative health care databases. Patients treated for esophageal cancer between 2013 and 2018 were included. The TI was time from diagnosis to treatment. Patients were assigned a geographical Local Health Integration Network on the basis of postal code. Covariates included patient, disease, and diagnosing physician characteristics. Quantile regression modeled TI length at the 50th and 90th percentile and identified associated factors. Results Of 7509 patients, 78% were male and most were aged between 60 and 69 years. The 50th and 90th percentile TI was 36 (interquartile range, 22-55) and 77 days, respectively. The difference between the Local Health Integration Network with the longest and shortest TI at the 50th and 90th percentile was 18 and 25 days, respectively. Older age (P < .0001), greater comorbidity (P = .0005), greater material deprivation (P = .001), rurality (P = .03), histology (P = .02), and treatment group (P < .0001) were associated with a longer median TI. Older age (P = .03), greater comorbidity (P = .003), greater material deprivation (P = .005), rurality (P = .04), and treatment group (P < .0001) were associated with a longer 90th percentile TI. Conclusions Geographic variability of time to treatment exists across Ontario. Investigation of facility-level differences is warranted. Patient and disease factors are associated with longer wait times. These results might inform future health care policy and resource allocation.

Abstract
Patients with resectable esophageal cancer are recommended to undergo chemoradiotherapy before esophagectomy. A longer time to surgery (TTS) and/or time to consultation (TTC) may be associated with inferior cancer-related outcomes and heightened anxiety. Thoracic cancer surgery centers (TCSCs) oversee esophageal cancer management, but differences in TTC/TTS between centers have not yet been examined. This Ontario population-level study used linked administrative healthcare databases to investigate patients with esophageal cancer between 2013–2018, who underwent neoadjuvant chemoradiotherapy and then surgery. TTC and TTS were time from diagnosis to the first surgical consultation and then to surgery, respectively. Patients were assigned a TCSC based on the location of the surgery. Patient, disease, and diagnosing physician characteristics were investigated. Quantile regression was used to model TTS/TTC at the 50th and 90th percentiles and identify associated factors. The median TTS and TTC were 130 and 29 days, respectively. The adjusted differences between the TCSCs with the longest and shortest median TTS and TTC were 32 and 18 days, respectively. Increasing age was associated with a 16-day longer median TTS. Increasing material deprivation was associated with a 6-day longer median TTC. Significant geographic variability exists in TTS and TTC. Therefore, the investigation of TCSC characteristics is warranted. Shortening wait times may reduce patient anxiety and improve the control of esophageal cancer.

Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
BACKGROUND The 8th edition UICC/AJCC TNM8 (Tumour, Nodes, Metastasis) melanoma staging system introduced several modifications from the 7th edition (TNM7), resulting in changes in survival and subgroup composition. We set out to address the limited validation of TNM8 (stages I-IV) in large population-based datasets. METHODS This retrospective cohort-study included 6,414 patients from the population-based Ontario Cancer Registry diagnosed with cutaneous melanoma between January 1, 2007 and December 31, 2012. Kaplan-Meier curves estimated the melanoma-specific survival (MSS) and overall survival (OS). Cox proportional hazard models were used to estimate adjusted hazard ratios for MSS and OS across stage groups. The Schemper-Henderson measure was used to assess the variance explained in the Cox regression. RESULTS In our sample, 21.3% of patients were reclassified with TNM8 from TNM7; reclassifications in stage II were uncommon, and 44.1% of patients in stage III were reclassified to a higher subgroup. Minimal changes in MSS curves were observed between editions, but the stage IIB curve decreased and the stage IIIC curve increased. For TNM8, Stage I (n = 4,556), II (n = 1,206), III (n = 598), and IV (n = 54) had an estimated 5-year MSS of 98.4%, 82.5%, 66.4%, and 14.4%, respectively. Within stage III, IIIA 5-year MSS was 91.7% while stage IIID was 23.5%. HRs indicated that TNM8 more evenly separates subgroups once adjusted for patient- and disease-characteristics. The variance in MSS explained by TNM7 and TNM8 is 18.9% and 19.7%, respectively. CONCLUSION TNM8 performed well in our sample, with more even separation of stage subgroups and a modest improvement in predictive ability compared to TNM7.

Abstract
OBJECTIVES Congestive heart failure (CHF) is the most common cause of 30-day inpatient readmission. Studies have found that early follow-up with primary care physicians (PCP) within 7 days of discharge may improve 30-day readmission rates; however, many have used a multidisciplinary discharge coordination team, which is not a resource at all centers. Here, the authors present a resident-driven quality improvement initiative using a monthly quality and safety award to increase early PCP follow-up for veterans discharged following admissions due to a CHF exacerbation. Primary outcomes were percentage of PCP follow-up within 7 days and median time to PCP follow-up. Secondary outcomes included percentage of patients attending a PCP visit within 7 days, 30-day readmission, and 30-day mortality. METHODS This prepost quasi-experimental cohort study evaluated 3 concurrent quality improvement interventions to increase PCP follow-up after CHF exacerbation. Process maps and Ishikawa diagrams examined the discharge process. Interventions included a standardized discharge scheduling order, monthly education on the process, and monthly aggregated performance feedback for each medical resident. A patient safety and quality award was given to the team with the highest rate of PCP appointments scheduled within 7 days. Patient characteristics and outcomes were gathered for a 6-month historic period and 6-month intervention period. Test of proportions and Wilcoxon Rank-Sum test were used to compare groups. RESULTS A total of 294 patients were discharged (161 in historic group and 133 in intervention group). Appointments scheduled within 7 days of discharge increased from 43% to 79% ( P < 0.001). Median time to PCP follow-up decreased from 8 to 6 days ( P < 0.001). Patients who completed (showed up to) a PCP appointment within 7 days increased from 16% to 41% ( P < 0.001). There was no impact on 30-day readmission or mortality; however, the number of study subjects was too small to rule out an effect. CONCLUSIONS A standardized discharge scheduling order, more robust resident education, and a monthly patient safety and quality award resulted in a significant increase in the rate of primary care follow-up within 7 days of CHF exacerbation.

Abstract
10567 Background: Asian Americans are the fastest-growing immigrant group in the U.S. As the oldest immigrant group on average, they are at heightened risk for cancer and other diseases. This study explored whether the risk is mitigated by the healthy immigrant effect (HIE), an epidemiological phenomenon that has been well documented among Latino immigrants. Evidence of a healthy immigrant effect among Asians as a whole or in specific Asian subgroups is limited, and almost none focus on the elderly with a cancer diagnosis. This original research study examines the evidence for an HIE in a large ethnically diverse sample of elderly persons with a cancer diagnosis. Methods: This is a retrospective observational study utilizing data collected across 14 regions of the U.S. SEER-Medicare Health Outcomes Survey (SEER-MHOS), a linked dataset sponsored by the NCI and the Center for Medicare & Medicaid Services. Logistic regression analyses were conducted to examine HIE among Asians in the aggregate and subgroups of Asians for smoking and body mass index (BMI), using survey language and ethnic concentration as proxies for nativity. Results: Asians, in the aggregate, had comparable social backgrounds and had better health behaviors (i.e., lower smoking and BMI) than non-Hispanic Whites. When Asians were disaggregated, Hawaiians and Japanese had higher smoking and obesity rates than Chinese. A protective effect was observed among Asians in the aggregate living in an ethnic enclave with lower smoking prevalence and lower BMI. Chinese respondents opting to complete surveys in their native language or living in ethnic enclaves were less likely to be overweight, but no significant associations were found in relation to their smoking. Conclusions: Support for a healthy immigrant effect was largely consistent for Asians in the aggregate with respect to both language and ethnic concentration, but support was mixed among subgroups of Chinese patients. The presence of the HIE suggests that the health status and needs of recent Asian immigrants seeking oncologic care may be different than Asians who have been in the U.S. longer. These findings suggest a need for community-based efforts to encourage preservation of a healthier living style observed among first-generation immigrants.

Abstract
Background Naturally occurring retirement communities (NORCs), unplanned communities with a high proportion of older adult residents, offer a model to support older adults to age well in place. The aim of this paper is to provide a comprehensive description of the methods used to identify and engage NORCs appropriate for the development of supportive service programming in Canada. Methods Three steps were used to identify and select NORCs in which to develop supportive service programming including: 1) identification of potential NORCs using Canadian Census Dissemination Areas, the Ontario Marginalization Index and Google Maps, 2) engagement of property owner/manager to determine the availability of common space for communal programming and willingness of the owner to support programming and, 3) engagement of older adult residents within the NORC to co-design programming. Results Four cities in the south-east, south-central, and south-west of Ontario, Canada were identified to develop NORCs with supportive service programming. Using the methods described, six NORCs were identified, landlords and older adult residents were engaged, and programs initiated between April 2018 and March 2019. The sites included two private high-rise apartments, a city-owned low-rise subsidized apartment complex, two multi-building private high-rise complexes and a mobile home community. An average of 35 (min 20, max 78) older adult members were engaged in an average of 20.5 unique activity sessions at each site per month. On average, social (54%) and physical activities (30%) were more common than nutritional (10%) and knowledge-sharing (8%). Conclusions The increased prevalence of unplanned, geographically-bound NORCs creates an opportunity for governments, social and health service providers and policy makers to support healthy aging in their communities. Our experience with the creation of six new NORCs with supportive service programming provides a tested set of methods that can be applied in other communities.

Abstract
223 Background: The current standard of care for men with intermediate- and high-risk localized prostate cancer treated with radiotherapy (RT) is the addition of androgen deprivation therapy (ADT). Presently, there are no validated predictive biomarkers to guide ADT use or duration in such men. Herein, we train and validate the first predictive biomarker for ADT use in prostate cancer using multiple phase III NRG Oncology randomized trials. Methods: Pre-treatment biopsy slides were digitized from five phase III NRG Oncology randomized trials of men receiving RT with or without ADT. The training set to develop the artificial intelligence (AI)-derived predictive biomarker included NRG/RTOG 9202, 9413, 9910, and 0126, and was trained to predict distant metastasis (DM). A multimodal deep learning architecture was developed to learn from both clinicopathologic and digital imaging histopathology data and identify differential outcomes by treatment type. After the model was locked, an independent biostatistician performed validation on NRG/RTOG 9408, a phase III randomized trial of RT +/- 4 months of ADT. The DM rates were calculated using cumulative incidence functions in biomarker positive and negative groups, and biomarker-treatment interaction was assessed using Fine-Gray regression such that death without DM was treated as a competing event. Results: Clinical and histopathological data was available for 5,654 of 7,957 eligible patients (71.1%). The training cohort included 3,935 patients and had a median follow-up of 13.6 years (IQR [10.2, 17.7]). After the AI-derived predictive ADT classifier was trained, it was validated in NRG/RTOG 9408 (n = 1719, median follow-up 17.6 years, IQR [15.0, 19.7]). In the NRG/RTOG 9408 validation cohort that had digital histopathology data, ADT significantly improved DM (HR 0.62, 95% CI [0.44, 0.87], p = 0.006), consistent with the published trial results. The biomarker-treatment interaction was significant (p-value = 0.0021). In patients with AI-biomarker positive disease (n = 673, 39%), ADT had a greater benefit compared to RT alone (HR 0.33, 95% CI [0.19, 0.57], p < 0.001). In the biomarker negative subgroup (n = 1046, 61%), the addition of ADT did not improve outcomes over RT alone (HR 1.00, 95% CI [0.64, 1.57], p = 0.99). The 15-year DM rate difference between RT versus RT+ADT in the biomarker negative group was 0.3%, vs biomarker positive group 9.4%. Conclusions: We have successfully validated in a phase III randomized trial the first predictive biomarker of ADT benefit with RT in localized intermediate risk prostate cancer using a novel AI-derived digital pathology-based platform. This AI-derived predictive biomarker demonstrates that a majority of patients treated with RT on NRG/RTOG 9408 did not require ADT and could have avoided the associated costs and side effects of this treatment.

Abstract
Background
Continuous quality improvement is important for cancer systems. However, collecting and compiling quality indicator data can be time-consuming and resource-intensive. Here we explore the utility and feasibility of linked routinely collected health data to capture key elements of quality of care for melanoma in a single-payer, universal health care setting.
Method
This pilot study utilized a retrospective population-based cohort from a previously developed linked administrative data set, with a 65% random sample of all invasive cutaneous melanoma cases diagnosed 2007–2012 in the province of Ontario. Data from the Ontario Cancer Registry was utilized, supplemented with linked pathology report data from Cancer Care Ontario, and other linked administrative data describing health care utilization. Quality indicators identified through provincial guidelines and international consensus were evaluated for potential collection with administrative data and measured where possible.
Results
A total of 7,654 cases of melanoma were evaluated. Ten of 25 (40%) candidate quality indicators were feasible to be collected with the available administrative data. Many indicators (8/25) could not be measured due to unavailable clinical information (e.g. width of clinical margins). Insufficient pathology information (6/25) or health structure information (1/25) were less common reasons. Reporting of recommended variables in pathology reports varied from 65.2% (satellitosis) to 99.6% (body location). For stage IB-II or T1b-T4a melanoma patients where SLNB should be discussed, approximately two-thirds met with a surgeon experienced in SLNB. Of patients undergoing full lymph node dissection, 76.2% had adequate evaluation of the basin.
Conclusions
We found that use of linked administrative data sources is feasible for measurement of melanoma quality in some cases. In those cases, findings suggest opportunities for quality improvement. Consultation with surgeons offering SLNB was limited, and pathology report completeness was sub-optimal, but was prior to routine synoptic reporting. However, to measure more quality indicators, text-based data sources will require alternative approaches to manual collection such as natural language processing or standardized collection. We recommend development of robust data platforms to support continuous re-evaluation of melanoma quality indicators, with the goal of optimizing quality of care for melanoma patients on an ongoing basis.

Background/Introduction
Coronary artery calcification is frequently encountered during percutaneous coronary intervention (PCI). It can reduce PCI success and increase intra-procedural and post-procedural complications, including stent embolization, under-expansion and mal-apposition. Intravascular lithotripsy (IVL) is a new tool developed to treat calcified coronary lesions.
Purpose
Retrospective analysis of all cases of intravascular lithotripsy performed within our local health district to examine patient and procedural characteristics and clinical outcomes.
Methods
All patients undergoing PCI with intravascular lithotripsy between September 2019-August 2021 within our local health district were analysed. Patient and procedural characteristics and clinical outcomes were recorded.
Results
67 patients (50 men) were included with mean age 71.4 ± 8.7years. Risk factors prevalence included smoking (34%), hypertension (82%), dyslipidaemia (69%) and diabetes (46%). Trans-radial artery access was used in 38 patients (57%). IVL was performed most commonly in the left anterior descending artery (52%),[Figure 1]. IVL was utilised in 9 chronic total occlusions and 12 bifurcation lesions. Intracoronary (IC) imaging was performed in 59 patients (88%), intravascular ultrasound in 41(61%) and optical coherence tomography in 18 (27%). 41 (69%) patients had imaging performed pre and post IVL and post PCI. IC imaging identified 14 cases with 270º calcification arc and 45 cases with 360º arc. Nine cases (13.4%) required rotational atherectomy prior to IVL (most commonly 1.75mm burr). Mean reference vessel diameter was 3.2 ± 0.3mm. Mean lesion length was 36.3 ± 16.5mm. Mean pre-PCI stenosis was 85.5 ± 10.8%. Drug eluting stents were successfully deployed in 57 cases (85%), 10 had balloon angioplasty alone. Mean stent length was 39.2 ± 17.8mm. Mean post-PCI stenosis was 4.5 ± 13.3% (median 0%). Figure 2 shows a statistically significant increase in minimum lumen diameter and minimum lumen area post-IVL and minimal-stent-area (MSA) post-PCI. Mean stent expansion was 83%. Mean screening time 35.8 ± 17.8 minutes with mean contrast used 207.3 ± 78.7mL. No sustained arrhythmias or side-branch loss occurred. Vessel rupture was recorded in one patient necessitating urgent cardiac surgery (due to oversized balloon) and in 4 cases the IVL balloon could not cross the lesion.
Conclusion
Our experience shows that IVL is safe and effective and facilitates stent delivery and expansion. Intracoronary imaging is important to determine the need for calcium modification and evaluate its success prior to stent delivery and to confirm optimised stent expansion. Abstract Figure.

Abstract
RATIONALE, AIMS AND OBJECTIVES Physician consultations are a limited resource. Anesthesiologists provide anaesthesia during surgery and procedures, prepare patients for surgery in preoperative clinics, and provide postoperative care. This study sought to evaluate current consultation usage patterns, with an aim to determine possible opportunities for efficiency. METHOD A retrospective comprehensive population-based cohort study was performed, evaluating all hospitals in the Canadian province of Ontario from 2002 to 2018. The main outcome measures were American Society of Anesthesiologists (ASA) classification of the patients, and whether the patients underwent surgery within 3 months following the anaesthesia consultation. RESULTS A cohort of 2,023,499 patients, and a total of 2,920,100 preoperative anaesthesia consultations was obtained. The number of consults per year doubled between 2003 (112,983/year) and 2017 (246,427/year), despite a less than 40% increase in practicing Canadian Anesthesiologists over this same timeframe. Each year, an average of 19.3% of the consults (range: 17.7-20.5%) were for patients that did not progress to having surgery. Of those that did have surgery following the anaesthesia consult, 37.2% were ASA Classification I or II. The most common surgical procedures (percent of total) following anaesthesia consult were: Knee arthroplasty (9.5%), hip arthroplasty (5.8%), cataract extraction (4.1%), repair of muscle of chest/abdomen (3.3%), hysterectomy (2.8%), and cholecystectomy (2.7%). CONCLUSIONS This study reveals data on utilization and trends over time of preoperative anaesthesia consultations. Potential opportunities for optimization were found, including patients who did not proceed to surgery, and healthier patients undergoing low to moderate risk surgery.

Abstract
ABSTRACT The opioid receptors are important regulators of pain, reward, and addiction. Limited evidence suggests the mu and delta opioid receptors form a heterodimer (MDOR), which may act as a negative feedback brake on opioid-induced analgesia. However, evidence for the MDOR in vivo is indirect and limited, and there are few selective tools available. We recently published the first MDOR-selective antagonist, D24M, allowing us to test the role of the MDOR in mice. We thus cotreated CD-1 mice with D24M and opioids in tail flick, paw incision, and chemotherapy-induced peripheral neuropathy pain models. D24M treatment enhanced oxymorphone antinociception in all models by 54.7% to 628%. This enhancement could not be replicated with the mu and delta selective antagonists CTAP, naltrindole, and naloxonazine, and D24M had a mild transient effect in the rotarod test, suggesting this increase is selective to the MDOR. However, D24M had no effect on morphine or buprenorphine, suggesting that only specific opioids interact with the MDOR. To find a mechanism, we performed phosphoproteomic analysis on brainstems of mice. We found that the kinases Src and CaMKII were repressed by oxymorphone, which was restored by D24M. We were able to confirm the role of Src and CaMKII in D24M-enhanced antinociception using small molecule inhibitors (KN93 and Src-I1). Together, these results provide direct in vivo evidence that the MDOR acts as an opioid negative feedback brake, which occurs through the repression of Src and CaMKII signal transduction. These results further suggest that MDOR antagonism could be a means to improve clinical opioid therapy.

Abstract
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors that absorb the light circulating in the cavity can deform the surface thermoelastically and thus increase losses by scattering light out of the resonant mode. The point absorber effect is a limiting factor in some high-power cavity experiments, for example, the Advanced LIGO gravitational-wave detector. In this Letter, we present a general approach to the point absorber effect from first principles and simulate its contribution to the increased scattering. The achievable circulating power in current and future gravitational-wave detectors is calculated statistically given different point absorber configurations. Our formulation is further confirmed experimentally in comparison with the scattered power in the arm cavity of Advanced LIGO measured by in situ photodiodes. The understanding presented here provides an important tool in the global effort to design future gravitational-wave detectors that support high optical power and thus reduce quantum noise.

Abstract
BACKGROUND Sepsis and cancer continue to be one of the leading causes of death in the United States. Concomitantly, hospitalizations for sepsis with underlying cancer over the years have shown a decrease in mortality. However, large-scale contemporary data on mortality trends in sepsis hospitalizations with underlying malignancy are lacking. RESEARCH QUESTION Are there any identifiable trends in patients hospitalized for sepsis with underlying malignancy versus without malignancy? STUDY DESIGN AND METHODS We performed a retrospective cohort study using the National Inpatient Sample database from 2008 to 2017 to identify sepsis hospitalizations with versus without cancer. Baseline variables and mortality trends were compared between the 2 groups. RESULTS Of the 19,160,734 sepsis hospitalizations identified between 2008 and 2017, 3,913,813 (20.4%) were associated with cancer and 15,246,921 (79.6%) did not have underlying malignancy. Compared with 2008 to 2009, the multivariable-adjusted odds ratio (aOR) of death was lower in 2016 to 2017 for both cancer (aOR: 0.55, 95% confidence interval [CI]: 0.53-0.57) and noncancer-associated (aOR: 0.55, 95% CI: 0.53-0.57) sepsis hospitalizations. The nonsignificant interaction term (P=0.2239) revealed that the rate of decline in mortality did not differ between the 2 groups. Stratification of the mortality in sepsis hospitalizations by various age groups revealed that the odds of death associated with cancer were highest in the younger population (18 to 44 y) with an aOR: 3.40, 95% CI: 3.24-3.57. The aOR: showed a declining trend with increasing age until cancer-associated admissions had slightly lower odds of mortality than the noncancer group at age 85 years old and older (aOR: 0.93, 95% CI: 0.91-0.95). CONCLUSION In the 10-year study period, mortality in cancer and noncancer-associated sepsis hospitalizations has shown a declining trend. Furthermore, differences in mortality between the 2 groups decreased with increasing age.

Abstract
OBJECTIVE To examine postoperative opioid-prescribing patterns following otologic surgery. STUDY DESIGN Retrospective population-based descriptive study. SETTING All hospitals in the Canadian province of Ontario. METHODS Of all patients with advanced ear surgery between July 1, 2012, and March 31, 2019, 7 cohorts were constructed: tympanoplasty with or without ossiculoplasty (n = 7812), atticotomy/limited mastoidectomy (n = 1371), mastoidectomy (n = 3717), semicircular canal occlusion (SCO; n = 179), stapedectomy (n = 2735), bone-implanted hearing aid insertion (n = 280), and cochlear implant (n = 2169). Prescriptions filled for narcotics postoperatively were calculated per morphine milligram equivalent (MME) opioid dose. Multivariable regression was used to determine predictors of higher opioid doses. RESULTS The mean ± SD MMEs prescribed were as follows: tympanoplasty with or without ossiculoplasty, 246.77 ± 1380.78; atticotomy/limited mastoidectomy, 283.32 ± 956.10; mastoidectomy, 280.56 ± 1018.50; SCO, 328.61 ± 1090.86; stapedectomy, 164.64 ± 657.18; bone-implanted hearing aid insertion, 326.11 ± 1054.66; and cochlear implant, 200.87 ± 639.93. SCO (odds ratio [OR], 1.69 [95% CI, 1.16-2.48]) and mastoidectomy (OR, 1.50 [95% CI, 1.36-1.66]) were associated with higher opioid doses than tympanoplasty-ossiculoplasty. Asthma (OR, 1.24 [95% CI, 1.12-1.38]), chronic obstructive pulmonary disease (OR, 1.29 [95% CI, 1.12-1.47]), myocardial infarction (OR, 1.33 [95% CI, 1.05-1.68]), diabetes (OR, 1.22 [95% CI, 1.08-1.39]), and substance-related and addictive disorders (OR, 2.59 [95% CI, 1.67-4.00]) were associated with higher opioid doses prescribed. Overall MME prescribed by year demonstrates a sharp drop from 2017-2018 to 2018-2019. CONCLUSION This large comprehensive population study provides insight into the prescribing patterns following otologic surgery. The large amounts prescribed and substantial variation require further study to determine barriers that limit good opioid-prescribing stewardship in the postoperative period.

Abstract
Abstract
BACKGROUND
Malignant meningiomas comprise 2–5% of all meningiomas. The process of malignant transformation when benign meningiomas (WHO grade I-II) become malignant (WHO grade III) has not previously been investigated in sequential tumour surgeries. Upregulation of FOXM1 expression and DREAM-complex repression have shown phenotypical subgroups correlating with WHO grade and aggressiveness. We investigated the RNA expression of 30 genes central to meningioma biology and 770 genes involved in neuroinflammatory pathways in primary and secondary malignant meningioma patients who underwent one to several operations.
MATERIALS AND METHODS
We identified a cohort of consecutive malignant meningioma patients treated at Rigshospitalet, Copenhagen from 2000–2020 (n=51) and gathered their malignant tumours and previous WHO grade I/II tumours. The malignant cohort (MC) was counter matched with a benign cohort (BC) where patients had no recurrences during follow-up. RNA expression signatures from 140 samples from the MC and 51 samples from the BC were analysed with the Nanostring Neuroinflammation panel customized with 30 genes known to be relevant in meningioma phenotypes.
RESULTS
49% of MC patients had a previous grade I/II meningioma making them secondary malignant meningioma patients. Progression-free survival calculated from first malignant surgery to first recurrence or death showed no significant difference in the primary vs. secondary patients. Preliminary results of single-gene analysis of MC tumours showed FOXM1, MYBL2, TOP2A, BIRC5 expression was higher in WHO grade III samples. Gene-expression signatures in the individual patients and gene ontology enrichment analyses are in process.
CONCLUSIONS
FOXM1, MYBL2, TOP2A, BIRC5 RNA expression levels seem to rise during malignant progression across patients. Gene-expression analysis using the Nanostring technology is feasible and a potentially powerful tool to distinguish meningiomas prone to malignant transformation from truly benign meningiomas.

Abstract
INTRODUCTION Infliximab remains a mainstay for treatment of inflammatory bowel disease (IBD), but a long infusion duration and subsequent monitoring can be burdensome to patients and health care providers. We assessed the safety of accelerated infusions for standard and dose-intensified infliximab regimens, and the effect on patient satisfaction and potential cost savings. METHODS Patients with IBD on a stable maintenance dose of infliximab and in clinical remission received one or more accelerated infusions; over 30 min if receiving standard-dose (5 mg/kg), or over 60 min if receiving dose-intensified infliximab (up to 10 mg/kg). Outcomes included incidence of reactions (acute or delayed), patient satisfaction, and potential cost savings. We also explored infliximab trough levels after one and three accelerated infusions. RESULTS 52 patients who received 150 infusions were studied. Incidence of reactions to accelerated infusions was 3.3% (3 out of 89) with standard-dose and 0% (out of 61) with dose-intensified infliximab. Reactions were delayed, mild, and self-limiting. None requiring drug cessation. Patient satisfaction was improved with shortened infusion time as compared to the patients' previous experiences (p = 0.00002). Mean plasma trough level of infliximab reduced from 9.3 mg/L (± 4.9) to 7.9 mg/L (± 4.1) (p = 0.02) with accelerated infusions, but none developed anti-infliximab antibodies. Nursing cost savings were estimated as $123.52 and $247.04 per-patient per-year for standard and dose-intensified infliximab, respectively. CONCLUSION Accelerated infliximab infusions for standard and dose-intensified regimens seems to be safe and improved patient satisfaction. Potential impact on drug trough levels requires further investigations. This article is protected by copyright. All rights reserved.
