1541 Background: Frailty is common in older adults undergoing major cancer surgery. Mounting evidence indicates multimodal interventions to optimize patient functional status by addressing vulnerabilities associated with frailty before surgery result in decreased complications and enhanced functional recovery. This study tested the effectiveness of OPTI-Surg, a surgical prehabilitation toolkit for improving surgical care and outcomes in older patients undergoing major cancer surgery. Here, we report results from the planned futility interim analysis (IA). Methods: Thoracic (T), gastrointestinal (GI), and urologic (GU) oncological surgery practices affiliated with NCI’s Community Oncology Research Program were randomized 1:1:1, stratified by practice type, to usual care (control), OPTI-Surg toolkit, or OPTI-Surg with an implementation coach. The toolkit was implemented at the practice level. It consisted of the 12-item Edmonton Frail Scale and guided recommendations for interventions directed at identified vulnerabilities. Eligible patients were adults ≥70 years old undergoing curative intent surgery for lung, gastrointestinal, or urologic cancers. Primary outcome was 8-week post-operative function (weekly caloric expenditure) derived from the validated Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire. A linear mixed model was used to compare usual care to the 2 OPTI-Surg arms combined, controlling for baseline function. Results: From July 2019 to October 2021, 225 patients, 50% of the total accrual goal, were enrolled from 29 practices, triggering the IA. Study was suspended to new patient accrual March to June 2020 due to the COVID-19 pandemic. There were no differences in demographics by arm (mean age 76.2 years; 46.4% women; 79.6% white; 20.4% lung resection, 69.8% major GI surgery, 9.8% total cystectomy). Of the 225 patients, 140 (47 Usual Care, 93 OPTI-Surg) were evaluable for the IA. There was no significant difference in post-operative function between OPTI-Surg and usual care (mean decrease of 0.59 kCal/week for OPTI-Surg patients and 0.19 kCal/week for usual care patients, p = 0.762, intraclass correlation = 0.033). Based on the futility analysis, the DSMB recommended closure of recruitment on September 16, 2022. Conclusions: Implementation of the OPTI-Surg toolkit did not significantly improve functional outcomes 8 weeks after surgery for patients aged 70 and older undergoing major cancer surgery compared to usual care. Future analysis of implementation and ethnographic data may identify reasons why significant differences between the intervention and usual care arms were not observed, potentially including disruptions due to the COVID-19 pandemic.

Introduction: An 82-year-old female presented to the emergency department with presyncope and was found to be bradycardic with proptosis and ophthalmoparesis. MRI revealed an extra-axial enhancing mass compressing the medulla and bilateral enhancing retro-orbital masses. Case Description: Imaging, including nuclear medicine bone scan, PET CT, and cardiac MRI raised the suspicion for a histiocytic neoplasm. These findings, along with a fibrohistiocytic infiltrate on bone biopsy and a BRAF V600E oncogenic mutation on plasma cell-free DNA confirmed a diagnosis of Erdheim-Chester disease. Discussion: These enhancing masses invoke a broad differential, including a histiocytic or granulomatous process, fungal infection, amyloidosis, IgG4 disease, and lymphoma. Systematic laboratory, radiologic, pathology, and genetic testing yielded a diagnosis of this rare histiocytic disorder with frequent neurologic involvement.

PURPOSE Compared with people living without HIV (PWOH), people living with HIV (PWH) and cancer have traditionally been excluded from immune checkpoint inhibitor (ICI) trials. Furthermore, there is a paucity of real-world data on the use of ICIs in PWH and cancer. METHODS This retrospective study included PWH treated with anti–PD-1- or anti–PD-L1-based therapies for advanced cancers. Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Objective response rates (ORRs) were measured per RECIST 1.1 or other tumor-specific criteria, whenever feasible. Restricted mean survival time (RMST) was used to compare OS and PFS between matched PWH and PWOH with metastatic NSCLC (mNSCLC). RESULTS Among 390 PWH, median age was 58 years, 85% (n = 331) were males, 36% (n = 138) were Black; 70% (n = 274) received anti–PD-1/anti–PD-L1 monotherapy. Most common cancers were NSCLC (28%, n = 111), hepatocellular carcinoma ([HCC]; 11%, n = 44), and head and neck squamous cell carcinoma (HNSCC; 10%, n = 39). Seventy percent (152/216) had CD4+ T cell counts ≥200 cells/µL, and 94% (179/190) had HIV viral load <400 copies/mL. Twenty percent (79/390) had any grade immune-related adverse events (irAEs) and 7.7% (30/390) had grade ≥3 irAEs. ORRs were 69% (nonmelanoma skin cancer), 31% (NSCLC), 16% (HCC), and 11% (HNSCC). In the matched mNSCLC cohort (61 PWH v 110 PWOH), 20% (12/61) PWH and 22% (24/110) PWOH had irAEs. Adjusted 42-month RMST difference was –0.06 months (95% CI, –5.49 to 5.37; P = .98) for PFS and 2.23 months (95% CI, –4.02 to 8.48; P = .48) for OS. CONCLUSION Among PWH, ICIs demonstrated differential activity across cancer types with no excess toxicity. Safety and activity of ICIs were similar between matched cohorts of PWH and PWOH with mNSCLC.

Abstract Biallelic pathogenic variants in the COASY gene have been associated with two distinct disease phenotypes, that is, COASY ‐protein associated neurodegeneration (CoPAN) and pontocerebellar hypoplasia type 12 (PCH 12). We present two siblings that independently presented with significant hypotonia and respiratory insufficiency at birth. Comprehensive genetic testing revealed homozygous variants within COASY , however, the progressive clinical and neuroradiologic findings described here are unique and have not been described previously. Magnetic resonance imaging showed progressive diffuse parenchymal loss throughout the bilateral cerebral hemispheres and atrophy of the basal ganglia and brainstem. As such, this article brings forth two additional cases of COASY ‐related disorder with abnormal newborn screening acylcarnitine profiles resembling carnitine palmitoyl transferase 1a (CPT1a) deficiency in two siblings who presented at birth with contractures, marked hypotonia and absent respiratory drive.

ImportanceLate-onset meningitis (LOM) has been associated with adverse neurodevelopmental outcomes in children born extremely preterm.ObjectiveTo report the incidence of LOM during birth hospitalization and neurodevelopmental outcomes at 18 to 26 months’ corrected age.Design, Setting, and ParticipantsThis cohort study is a secondary analysis of a multicenter prospective cohort of children born at 22 to 26 weeks’ gestation between 2003 and 2017 with follow-up from 2004 to 2021. The study was conducted at 25 Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network centers.ExposuresCulture-confirmed LOM.Main Outcomes and MeasuresIncidence and microbiology of LOM (2003-2017); lumbar puncture (LP) performance in late-onset sepsis (LOS) evaluations (2011-2017); composite outcome of death or neurodevelopmental impairment (NDI; 2004-2021).ResultsAmong 13 372 infants (median [IQR] gestational age, 25.4 [24.4-26.1] weeks; 6864 [51%] boys), LOM was diagnosed in 167 (1%); LOS without LOM in 4564 (34%); and neither LOS nor LOM in 8641 (65%). The observed incidence of LOM decreased from 2% (95% CI, 1%-3%) in 2003 to 0.4% (95% CI, 0.7%-1.0%) in 2017 (P &amp;lt; .001). LP performance in LOS evaluations decreased from 36% (95% CI, 33%-40%) in 2011 to 24% (95% CI, 21%-27%) in 2017 (P &amp;lt; .001). Among infants with culture-confirmed LOS, LP performance decreased from 58% (95% CI, 51%-65%) to 45% (95% CI, 38%-51%; P = .008). LP performance varied by center among all LOS evaluations (10%-59%, P &amp;lt; .001) and among those with culture-confirmed LOS (23%-79%, P &amp;lt; .001). LOM occurred in the absence of concurrent LOS in 27 of 167 cases (16%). The most common LOM isolates were coagulase-negative Staphylococcus (98 [59%]), Candida albicans (38 [23%]), and Escherichia coli (27 [16%]). Death or NDI occurred in 22 of 46 children (48%) with LOM due to coagulase-negative Staphylococcus, 43 of 67 (64%) due to all other bacterial pathogens, and 26 of 33 (79%) due to fungal pathogens. The adjusted relative risk of death or NDI was increased among children with LOM (aOR, 1.53; 95% CI, 1.04-2.25) and among those with LOS without LOM (aOR, 1.41; 95% CI, 1.29-1.54) compared with children with neither infection.Conclusions and RelevanceIn this cohort study, LP was performed with decreasing frequency, and the observed incidence of LOM also decreased. Both LOM and LOS were associated with increased risk of death or NDI; risk varied by LOM pathogen. The full association of LOM with outcomes of children born extremely preterm may be underestimated by current diagnostic practices.

The COVID-19 pandemic has significantly impacted the production, distribution, and demand of essential laboratory supplies worldwide. In 2021, severe shortages in required laboratory supplies such as blood collection tubes, butterfly needles, and blood gas syringes became a critical issue across Canada. Many hospitals or institutions had to instruct physicians and patients to limit laboratory testing where possible and, in some cases, required emergency shipments of tubes from alternative vendors or nearby hospitals. Laboratory testing is ubiquitous in managing patients. It is used for screening, diagnosis, and monitoring purposes. With limited blood collection tubes, consideration for restricting non-urgent testing is needed to conserve supply and protect acute care departments that manage critically ill patients. In addition, laboratories across Canada have experienced significant staffing shortages, resulting in an even greater need for appropriate laboratory utilization. Consequently, the Canadian Society of Clinical Chemists (CSCC) and the Canadian Association of Medical Biochemists (CAMB) curated utilization recommendations for both hospital and primary care settings in collaboration with Choosing Wisely Canada (CWC). These recommendations were specifically selected from those previously published by Choosing Wisely Canada (CWC), with impact statements and rationales added to conserve at-risk laboratory resources. Supply chain disruptions of clinical laboratory resources are expected to continue throughout 2022, indicating that now, more than ever, a focus on appropriate laboratory utilization is essential.
