    Abstract Neutrophils constitute a considerable proportion of all leukocytes found in tumors and are essential for promoting tumor growth. In this issue, Linde et al. demonstrate that an antibody cocktail therapy consisting of tumor necrosis factor (TNF), anti-CD40 monoclonal antibody, and tumor-binding antibody can boost the anti-tumor activity of neutrophils.

    Abstract To combat racial/ethnic and socioeconomic health disparities associated with COVID-19 in our surrounding communities, the Cleveland Clinic Community Health & Partnership team developed a comprehensive program focused on connecting and communicating with local officials, faith-based organizations, and individual community members. Since March of 2020, our team has donated resources (e.g., personal protective equipment) to local organizations, referred thousands of community members to community or clinical resources, and partnered with federally-qualified health centers to support community COVID-19 testing. Future work will include the use of these networks to deploy the COVID-19 vaccine.

    Abstract Iodine is crucial for thyroid hormone synthesis and fetal neurodevelopment. Major dietary sources of iodine in the United States are dairy products and iodized salt. Potential consequences of iodine deficiency are goiter, hypothyroidism, cretinism, and impaired cognitive development. Although iodine status in the United States is considered sufficient at the population level, intake varies widely across the population, and the percentage of women of childbearing age with iodine deficiency is increasing. Physicians should be aware of the risks of iodine deficiency and the indications for iodine supplementation, especially in women who are pregnant or lactating.

    Abstract Introduction: Violet Program (ViP) was developed
    Methods and analysis: This study will be conducted in three phases: 1. development of initial program theory (IPT), 2. testing of programme theory, and 3. refinement of IPT. First, IPT will be elicited through review of programme documents, scoping review of reviews and in-depth interviews with stakeholders involved in the conceptualization of ViP. Then, a convergent mixed method study will be conducted to assess contexts (C), mechanisms (M) and outcomes (O) to test the IPT through interviews with stakeholders, surveys and analysis of program and administrative databases. Based on findings gathered and through consultation with respective stakeholders, IPT will be refined to highlight what works (outcomes), how (mechanisms) and for whom under what conditions (contexts).

    Abstract Adrenocortical insufficiency may arise through primary failure of the adrenal glands or due to lack of ACTH stimulation as a result of pituitary or hypothalamic dysfunction. Prolonged administration of exogenous steroids will suppress the hypothalamic-pituitary-adrenal axis, and hence cortisol secretion. We review briefly the causes, investigation, and treatment of adrenal insufficiency, and highlight aspects of particular relevance to patients with adrenal tumors.

    Abstract Background: Therapeutic drug monitoring of tumor necrosis factor inhibitors, such as adalimumab (ADM), is increasingly being performed for the management of autoimmune diseases. However, there can be significant variation in drug and antibody concentrations obtained by different assay methods. The aim of this study was to compare the performance of 4 enzyme-linked immunosorbent assay (ELISA) kits for measuring ADM and anti-ADM antibodies.
    Method: Dilutions of ADM or anti-ADM spiked sera were assessed for recovery rate and precision using the following 4 kits: LISA-Tracker (Theradiag, Croissy-Beaubourg, France), Promonitor (Grifols, Barcelona, Spain), Ridascreen (R-Biopharm, Darmstadt, Germany), and Shikari (Matriks Biotek, Gölbaşi/Ankara Turkey). Interference samples were also assessed.
    Results: At the therapeutic concentration, ADM detection was comparable among the 4 ELISA kits. Lisa-Tracker and Shikari kits produced low-range false positive results in normal sera. Infliximab and etanercept caused false positives in Lisa-Tracker and Shikari kits. Anti-ADM antibody ELISA kits performed differently with spiked samples because of different measuring units and ranges. Ridascreen and Shikari kits were dose responsive across the entire standard curve and correlated well with each other (r = 0.997). Cross reactivity was observed in rheumatoid factor positive sera tested on the Promonitor anti-ADM kit.
    Conclusions: All ADM kits tested were dose responsive within the therapeutic range and correlated well. The significance of observed low-range false positives and cross reactivity with infliximab in LISA-Tracker and Shikari kits is dependent on the indications received for testing in the laboratory. Anti-ADM ELISA kits produced varied results for spiked sera; however, they showed good precision. Inter-kit variability suggested that anti-ADM levels should be compared only when using the same method.

    Abstract Introduction: Identifying peripheral arterial disease (PAD) during diabetic foot screening (DFS) is crucial in reducing the risk of diabetic foot ulcerations and lower limb amputations. Screening assessments commonly used include absolute systolic toe pressure (ASTP) and toe-brachial index (TBI). There is a lack of research defining the threshold values of both assessment methods. We aimed to compare the accuracy of ASTP and TBI and establish optimal threshold values of ASTP and TBI with reference to the internationally accepted ankle-brachial pressure index (ABPI) screening test, for a multiethnic diabetic population in Singapore.
    Methods: A retrospective, observational study of DFS results from January 2017 to December 2017 was conducted. Receiver operating characteristic analysis was conducted for ASTP and TBI using the internationally accepted ABPI cut-off value of ≤0.9 to indicate PAD.
    Results: A total of 1,454 patients with mean (standard deviation) age of 63.1 (12.4) years old were included. There were 50.8% men and 49.2% women, comprising 69.7% Chinese, 13.5% Indian, 10.1% Malay and 6.7% other ethnicities. Areas under the curve for ASTP and TBI were 0.89 (95% confidence interval [Cl] 0.85-0.94) and 0.94 (95% Cl 0.90-0.98), respectively, and the difference was statistically significant (
    Conclusion: ASTP or TBI may be used to detect ABPI-determined PAD in DFS. The optimal threshold values derived from a multiethnic Asian diabetic population were <95.5mmHg for ASTP and <0.7 for TBI.

    Abstract Introduction: In the National University Cancer Institute, Singapore (NCIS), 2 pilot programs providing (i) surgical prehabilitation before cancer surgery and (ii) geriatric oncology support for older adults planned for chemotherapy and/or radiotherapy were merged to form the Geriatric Oncology Longitudinal End to eNd (GOLDEN) program in 2019 to support patients from the time of their cancer diagnosis, through their treatment process, to cancer survivorship.
    Methods and materials: Older adults aged ≥65 years were enrolled in either surgical prehabilitation, the geriatric medical oncology (GO) arm, or both. All patients undergo a geriatric assessment. We assessed if patients had a change in treatment plans based on GOLDEN recommendations, and the impact on patient related outcomes.
    Results: There were 777 patients enrolled in the GOLDEN program over 2 years; 569 (73%) were enrolled in surgical prehabilitation, 308 (40%) were enrolled in the GO arm, with 100 (12.8%) enrolled in both. 56.9% were females. Median age was 73. Lower gastrointestinal (51.2%) and hepatobiliary cancers (24.1%) were the most common cancer types. 43.4% were pre-frail and 11.7% were frail. Of the 308 patients in the GO arm, 86.0% had geriatric syndromes, while 60.7% had a change in their treatment plans based on GOLDEN recommendations. 31.5% reported an improved global health status, while 38.3% maintained their global health status. 226 (73%) responded that they had benefited from the GOLDEN.
    Conclusion: More than half of the population was either pre-frail or frail. Amongst those in the GO arm, the majority had geriatric syndromes and had a change in their treatment plans based on GOLDEN recommendations. Majority reported either improvement or maintenance in global health status, with most feeling they have benefited from the program. Further evaluation of the longitudinal geriatric hematology-oncology program for cancer-related outcomes and sustainability should be carried out.

    Abstract Background: Health-care organisations in England that are rated as inadequate for leadership and one other domain enter the Special Measures for Quality regime to receive support and oversight. A 'watch list' of challenged providers that are at risk of entering Special Measures for Quality also receive support. Knowledge is limited about whether or not the support interventions drive improvements in quality, the costs of the support interventions and whether or not the support interventions strike the right balance between support and scrutiny.
    Objective: To analyse the responses of trusts to the implementation of (1) interventions for Special Measures for Quality trusts and (2) interventions for challenged provider trusts to determine their impact on these organisations' capacity to achieve and sustain quality improvements.
    Design: This was rapid research comprising five interrelated workstreams: (1) a literature review using systematic methods; (2) an analysis of policy documents and interviews at the national level; (3) eight multisite, mixed-methods trust case studies; (4) an analysis of national performance and workforce indicators; and (5) an economic analysis.
    Results: The Special Measures for Quality/challenged provider regimes were intended to be 'support' programmes. Special Measures for Quality/challenged provider regimes had an emotional impact on staff. Perceptions of NHS Improvement interventions were mixed overall. Senior leadership teams were a key driver of change, with strong clinical input being vital. Local systems have a role in improvement. Trusts focus efforts to improve across multiple domains. Internal and external factors contribute to positive performance trajectories. Nationally, only 15.8% of Special Measures for Quality trusts exited the regime in 24 months. Entry into Special Measures for Quality/challenged provider regimes resulted in changes in quality indicators (such the number of patients waiting in emergency departments for more than 4 hours, mortality and the number of delayed transfers of care) that were more positive than national trends. The trends in staff sickness and absence improved after trusts left Special Measures for Quality/challenged provider regimes. There was some evidence that staff survey results improved. No association was found between Special Measures for Quality/challenged provider regimes and referral to treatment times or cancer treatment waiting times. NHS Improvement spending in case study trusts was mostly directed at interventions addressing 'training on cultural change' (33.6%), 'workforce quality and safety' (21.7%) and 'governance and assurance' (18.4%). The impact of Special Measures for Quality on financial stability was equivocal; most trusts exiting Special Measures for Quality experienced the same financial stability before and after exiting.
    Limitations: The rapid research design and 1-year time frame precludes longitudinal observations of trusts and local systems. The small number of indicators limited the quantitative analysis of impact. Measurement of workforce effects was limited by data availability.
    Conclusions: Empirical evidence of positive impacts of Special Measures for Quality/challenged provider regimes were identified; however, perceptions were mixed. Key lessons were that (1) time is needed to implement and embed changes; (2) ways to mitigate emotional costs and stigma are needed; (3) support strategies should be more trust specific; (4) poor organisational performance needs to be addressed within local systems; (5) senior leadership teams with stability, strong clinical input and previous Special Measures for Quality experience helped to enact change; (6) organisation-wide quality improvement strategies and capabilities are needed; (7) staff engagement and an open-listening culture promote continuous learning and a quality improvement 'mindset', which is critical for sustainable improvement; and (8) consideration of the level of sustainable funds required to improve patients' outcomes is needed.
    Future work: Future work could include evaluating recent changes to the regimes, the role of local systems and longitudinal approaches.
    Study registration: The review protocol is registered with PROSPERO (CRD42019131024).
    Funding: This project was funded by the National Institute for Health and Care Research (NIHR) Health and Social Care Delivery Research programme and will be published in full in
