Development and investigation of a non-invasive disease severity index for inflammatory bowel disease.

Introduction: The disease severity index (DSI) encapsulates the inflammatory bowel disease (IBD) burden but requires endoscopic investigations. This study developed a non-invasive DSI using faecal calprotectin (DSI-fCal) and faecal myeloperoxidase (DSI-fMPO) instead of colonoscopy.

Methods: Adults with IBD were recruited prospectively.

Editor's Choice - Reduction of Major Amputations after Surgery versus Endovascular Intervention: The BEST-CLI Randomised Trial.

Objective: BEST-CLI, an international randomised trial, compared an initial strategy of bypass surgery with endovascular treatment in chronic limb threatening ischaemia (CLTI). In this substudy, overall amputation rates and risk of major amputation as an initial or subsequent outcome were evaluated.

Methods: A total of 1 830 patients were randomised to receive surgical or endovascular treatment in two parallel cohorts: patients with adequate single segment great saphenous vein (SSGSV) (n = 1 434) were assigned to cohort 1; and patients without adequate SSGSV (n = 396) were assigned to cohort 2.

Pivoting Continuing Professional Development During the COVID-19 Pandemic: A Narrative Scoping Review of Adaptations and Innovations.

Introduction: Most formal continuing professional development (CPD) opportunities were offered in person until March 2020 when the COVID-19 pandemic disrupted traditional structures of CPD offerings. The authors explored the adaptations and innovations in CPD that were strengthened or newly created during the first 16 months of the pandemic.

Methods: The objectives of the narrative review were to answer the following questions: (1) what types of adaptations to CPD innovations are described? and (2) what may shape future innovations in CPD? The following databases were searched: Medline, Embase, CINAHL, and ERIC to identify the literature published between March 2020 to July 2021.

Conflicting European and North American Society Abdominal Aortic Aneurysm (AAA) Volume Guidelines Differentially Discriminate Peri-operative Mortality After Elective Open AAA Repair.

Objective: The European Society for Vascular Surgery (ESVS) guidelines endorse a minimum abdominal aortic aneurysm (AAA) repair volume of 20 open (OAR) and or endovascular (EVAR) AAA repair procedures per year as a proxy for high quality care. In contrast, the Society for Vascular Surgery (SVS) espouses 10 exclusively OARs per year. Given the differences in these volume standards and definitions, debate persists regarding surgeon credentialing and healthcare resource allocation.

Five Year Survival in Medicare Patients Undergoing Interventions for Peripheral Arterial Disease: a Retrospective Cohort Analysis of Linked Registry Claims Data.

Objective: To justify the up front risks of offering elective interventions for intermittent claudication (IC), patients should have reasonable life expectancy to derive durable clinical benefits. Open surgery for chronic limb threatening ischaemia (CLTI) is maximally beneficial in patients surviving ≥ 2 years. The aim was to assess long term survival after IC and CLTI interventions.

The Association Between Body Mass Index and Death Following Elective Endovascular and Open Repair of Abdominal Aortic Aneurysms in the Vascular Quality Initiative.

Objective: The effect of body mass index (BMI) on post-operative outcomes after abdominal aortic aneurysm (AAA) repair remains poorly defined. The association between BMI and death following elective endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) of AAA in a large national quality registry is investigated.

Methods: All elective AAA repairs within the Society for Vascular Surgery Vascular Quality Initiative (VQI; 2010 to September 2021) were reviewed (EVAR, n = 53 426; OAR, n = 9 479).

A Radiation Biological Analysis of the Oxygen Effect as a Possible Mechanism in FLASH.

The delivery of radiation at an ultra-high dose rate (FLASH) is an important new approach to radiotherapy (RT) that appears to be able to improve the therapeutic ratio by diminishing damage to normal tissues. While the mechanisms by which FLASH improves outcomes have not been established, a role involving molecular oxygen (O) is frequently mentioned. In order to effectively determine if the protective effect of FLASH RT occurs via a differential direct depletion of O (compared to conventional radiation), it is essential to consider the known role of O in modifying the response of cells and tissues to ionising radiation (known as 'the oxygen effect').

A Systematic Review of the Recruitment and Outcome Reporting by Sex and Race/Ethnicity in Stent Device Development Trials for Endovascular Abdominal Aortic Aneurysm Repair.

Background: Women and racial/ethnic minority groups have been shown to experience poor outcomes after endovascular aortic aneurysm repair (EVAR). One potential reason is the rare inclusion of these populations in initial phases of device development. The objective of this systematic review is to understand enrollment and outcome reporting by sex and race/ethnicity in industry-funded EVAR device development trials.

Drivers of blood use in paediatric trauma: A retrospective cohort study.

Objectives: We asked whether age or injury severity drives blood use patterns in paediatric trauma.

Background: Transfusion for paediatric trauma care is complicated by known developmental differences in coagulation and injury patterns.

Methods/materials: We linked 10 years of Trauma Registry and blood bank data, 2011-2020, for all acute trauma patients aged <18 treated at a large US Level 1 adult and paediatric trauma centre.

High-energy open-fracture model with initial experience of fluorescence-guided bone perfusion assessment.

High-energy orthopedic injuries cause severe damage to soft tissues and are prone to infection and healing complications, making them a challenge to manage. Further research is facilitated by a clinically relevant animal model with commensurate fracture severity and soft-tissue damage, allowing evaluation of novel treatment options and techniques. Here we report a reproducible, robust, and clinically relevant animal model of high-energy trauma with extensive soft-tissue damage, based on compressed air-driven membrane rupture as the blast wave source.

Review of Opioid Sparing Interventional Pain Management Options and Techniques for Radiofrequency Ablations for Sacroiliac Joint Pain.

Purpose Of Review: The goal of this clinical review was to provide an update about the existing treatment options and associated evidence for various radiofrequency ablation techniques for sacroiliac joint pain. An electronic literature search on radiofrequency for the treatment of sacroiliac joint pain was conducted using PubMed, NCBI and Google Scholar. The following search keywords were used: radiofrequency ablation (cooled, pulsed, conventional, bipolar, intra-articular), sacroiliac joint and sacroiliac pain.

Editor's Choice - Real World Study of Mortality After the Use of Paclitaxel Coated Devices in Peripheral Vascular Intervention.

Objective: This observational cohort study examined outcomes after peripheral vascular intervention (PVI) with paclitaxel coated devices (PCD) and non-PCD, and evaluated heterogeneity of treatment effect in populations of interest.

Methods: The study included patients undergoing percutaneous transluminal angioplasty and or stent placement between 1 October 2015 and 31 December 2018 in the Vascular Quality Initiative Registry linked to Medicare claims. It determined differences in patient mortality and ipsilateral major amputation after PVI with PCD and non-PCD using Kaplan-Meier analyses and Cox regressions with inverse probability weighting in three cohorts: (A) patients treated for femoropopliteal or infrapopliteal occlusive disease with or without any other concurrent treatment (n = 11 452); (B) those treated for isolated superficial femoral or popliteal artery disease (n = 5 519); and (C) patients with inclusion criteria designed to approximate RCT populations (n = 2 278).

Midterm Outcomes of Endovascular Repair of Aortic Arch Aneurysms with the Gore Thoracic Branch Endoprosthesis.

Objective: Aortic aneurysms involving aortic arch vessels are anatomically unsuitable for standard thoracic endovascular repair (TEVAR) without cervical debranching of the arch vessels. Three year outcomes of a single branched thoracic endograft following previous publication of peri-operative and one year outcomes are reported.

Methods: This was a multicentre feasibility trial of the GORE TAG Thoracic Branch Endoprosthesis (TBE), a thoracic endovascular graft incorporating a single retrograde branch for aortic arch vessel perfusion.

Clinical Radiofrequency Ablation Outcomes of Combined Sensory Nerve Branch and Dorsal Entry Root Zone Complex Lesions for Sacroiliac Joint Complex Pain.

Background: Chronic lower back pain (LBP) with or without leg pain (LP) is the most commonly reported anatomical site of pain among Canadian adults with chronic pain. A common cause for LBP and LP arises from dysfunction of the sacroiliac joint (SIJ) complex. When conventional medical management or rehabilitative efforts for SIJ-related LBP and LP fail to provide analgesia, pulsed radiofrequency (PRF) and/or radiofrequency ablation (RFA) of the dorsal entry root zone complex lesions (DREZC) and/or their more peripheral branches can also be a suitable means for treatment.

The disease severity index for inflammatory bowel disease is associated with psychological symptoms and quality of life, and predicts a more complicated disease course.

Background: The Disease Severity Index (DSI) is a novel tool to predict disease severity in inflammatory bowel disease (IBD). However, its ability to predict disease complications and the presence of psychosocial comorbidity is unclear.

Aims: To assess prospectively associations between the DSI and psychological symptoms, quality-of-life (QoL) and disease outcomes in an IBD cohort.

A Standard Set of Value-Based Patient-Centered Outcomes and Measures of Overall Health in Adults.

Background: The definition of population-specific outcomes is an essential precondition for the implementation of value-based health care. We developed a minimum standard outcome set for overall adult health (OAH) to facilitate the implementation of value-based health care in tracking, comparing, and improving overall health care outcomes of adults across multiple conditions, which would be of particular relevance for primary care and public health populations.

Methods: The International Consortium for Health Outcomes Measurement (ICHOM) convened an international panel (patients, clinicians, and topic experts).

Establishing the phenotypic spectrum of ZTTK syndrome by analysis of 52 individuals with variants in SON.

Zhu-Tokita-Takenouchi-Kim (ZTTK) syndrome, an intellectual disability syndrome first described in 2016, is caused by heterozygous loss-of-function variants in SON. Its encoded protein promotes pre-mRNA splicing of many genes essential for development. Whereas individual phenotypic traits have previously been linked to erroneous splicing of SON target genes, the phenotypic spectrum and the pathogenicity of missense variants have not been further evaluated.

The expanding capability and clinical relevance of molecular diagnostic technology to identify and evaluate EGFR mutations in advanced/metastatic NSCLC.

Epidermal growth factor receptor (EGFR) mutation testing in advanced non-small-cell lung cancer (NSCLC) has evolved rapidly over the past decade, largely triggered by the introduction of the targeted EGFR tyrosine kinase inhibitors (TKIs). Initially used to detect common EGFR mutations and determine the most appropriate first-line therapy at diagnosis, testing methodologies have expanded to test for multiple mutations at multiple time points throughout the disease course. Here we review the current mutation testing approaches, including types of biopsies, and the available assays commonly used in the clinic.

The Development and Usability of the AMPREDICT Decision Support Tool: A Mixed Methods Study.

Objective: Amputation level decision making in patients with chronic limb threatening ischaemia is challenging. Currently, evidence relies on published average population risks rather than individual patient risks. The result is significant variation in the distribution of amputation levels across health systems, geographical regions, and time.
