RESUMO
OBJECTIVE: Consensus guidelines on the optimal management of infected arterial pseudoaneurysms secondary to groin injecting drug use are lacking. This pathology is a problem in the UK and globally, yet operative management options remain contentious. This study was designed to establish consensus to promote better management of these patients, drawing on the expert experience of those in a location with a high prevalence of illicit drug use. METHODS: A three round modified Delphi was undertaken, systematically surveying consultant vascular surgeons in the UK and Ireland using an online platform. Seventy five vascular surgery units were invited to participate, with one consultant providing the unit consensus practice. Round one responses were thematically analysed to generate statements for round two. These statements were evaluated by participants using a five point Likert scale. Consensus was achieved at a threshold of 70% or more agreement or disagreement. Those statements not reaching consensus were assessed and modified for round three. The results of the Delphi process constituted the consensus statement. RESULTS: Round one received 64 (86%) responses, round two 59 (79%) responses, and round three 62 (83%) responses; 73 (97%) of 75 units contributed. Round two comprised 150 statements and round three 24 statements. Ninety one statements achieved consensus agreement and 15 consensus disagreement. The Delphi statements covered sequential management of these patients from diagnosis and imaging, antibiotics and microbiology, surgical approach, wound management, follow up, and additional considerations. Pre-operative imaging achieved consensus agreement (97%), with computerised tomography angiography being the modality of choice (97%). Ligation and debridement without arterial reconstruction was the preferred approach at initial surgical intervention (89%). Multidisciplinary management, ensuring holistic care and access to substance use services, also gained consensus agreement. CONCLUSION: This comprehensive consensus statement provides a strong insight into the standard of care for these patients.
RESUMO
BACKGROUND: The UK has one of the highest rates of recreational drug use and consequent deaths in Europe. Scotland is the "Drug deaths capital of Europe." Intravenous drug use can result in limb- and life-threatening pathology. This study aimed to characterise limb-related admissions associated with intravenous drug use, outcomes and healthcare expenditure. METHODS: Retrospective data collection between December 2011 and August 2018. Patients were identified through discharge codes. Admission details were extracted from electronic records and a database compiled. Statistical analyses were performed using Statistical Package for the Social Science, P < 0.05 denoted significance. RESULTS: There were 558 admissions for 330 patients (1-9 admissions/patient), mean age 37 years (+/-7.6 SD) and 196 (59.2%; 319 admissions, 57.2%) were male. Three hundred forty-eight (62.4%) admissions were to surgical specialties, predominantly Vascular Surgery (247). Including onward referrals, Vascular ultimately managed 54.8% of admissions. Patients presented with multiple pathologies: 249 groin abscesses; 38 other abscesses; 74 pseudoaneurysms; 102 necrotising soft tissue infections (NSTI); 85 cellulitis; 138 deep venous thrombosis (DVTs); 28 infected DVTs and 70 other diagnoses. Two hundred and seventy-seven admissions (220 patients) required operations, with 361 procedures performed (1-7 operations/admission). There were 24 major limb amputations and 74 arterial ligations. Eleven amputations were due to NSTI and 13 followed ligation (17.6% of ligations). During follow-up 50 (15.2%) patients died, of which 6 (12%) had amputations (OR 3.2, 95% CI 1.04-9.61, P = 0.043). Cumulative cost of acute care was £4,783,241. CONCLUSIONS: Limb-related sequalae of intravenous drug use represents a substantial surgical workload, especially for Vascular. These are complex, high-risk patients with poor outcomes and high healthcare costs.

BACKGROUND: Much of the emphasis for primary care management of chronic kidney disease (CKD) has focused on cardiovascular risk; however, many patients die of other causes. Aim. In order to guide future primary care management of CKD, we report the causes of death from a large U.K. CKD cohort linked to health care administrative data. DESIGN, SETTING AND METHODS: The Grampian Laboratory Outcomes Mortality and Morbidity Study (GLOMMS-1) is a community cohort of people with established CKD, identified in 2003 and followed up for 6 years. Causes of death were available from death certificates. The relative likelihood of different causes of death was compared to the general population. RESULTS: When standardized for age and sex, mortality was 4.7 (95% confidence interval 4.5-4.9) times higher in GLOMMS-1 than the general population. Non-cardiovascular diseases accounted for 1076 (50.9%) of deaths, 3.7 times more common than in the age- and sex-matched general population. For those with stages 3 and 4 CKD, without cardiovascular disease at baseline, a non-cardiovascular cause accounted for almost two-thirds of deaths. In those 75 years and older, dementia and falls were among the main non-cardiovascular causes of death. CONCLUSIONS: Mortality in those with CKD is high, with non-cardiovascular diseases accounting for more than half of all deaths. While there is evidence that intervention may benefit those at risk of cardiovascular death, most of the non-cardiovascular causes of death identified were not readily amenable to prevention. A mechanism to identify which patients may benefit from intervention to prevent cardiovascular disease or renal disease progression is needed.

INTRODUCTION: People who inject drugs are at risk of a range of injecting-related infections and injuries, which can threaten life and limb. In parallel to escalating rates of drug-related deaths seen in Scotland and the UK, there has also been an increase in hospital admissions for skin and soft tissue infections related to injecting drug use. One such injecting complication is the infected arterial pseudoaneurysm, which risks rupture and life-threatening haemorrhage. Surgical management options for the infected arterial pseudoaneurysm secondary to groin injecting drug use remain contentious, with some advocates for ligation and debridement alone, whilst others promote acute arterial reconstruction (suture or patch repair, bypass or, more recently, endovascular stent-graft placement). Rates of major lower limb amputations related to surgical management for this pathology vary in the literature. This review aims to evaluate the outcomes of arterial ligation alone compared with arterial reconstruction, including open and endovascular options, for the infected arterial pseudoaneurysm secondary to groin injecting drug use. METHODS AND ANALYSIS: The methods will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Three electronic databases will be searched and the resultant papers screened according to the study inclusion and exclusion criteria (detailed in the Population, Intervention, Comparison, Outcomes and Study design statement). Grey literature will be excluded. All papers at each stage will be screened by two independent authors, with disagreements arbitrated by a third. Papers will be subject to appropriate standardised quality assessments. PRIMARY OUTCOME: Major lower limb amputation. SECONDARY OUTCOMES: Reintervention rate, rebleeding rate, development of chronic limb-threatening ischaemia 30-day mortality and claudication. ETHICS AND DISSEMINATION: This is a systematic review based on previously conducted studies, therefore, no ethical approval is required. The results of this work will be published in a peer-reviewed journal and presented at relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42022358209.

New approaches to managing infections in cardiac and peripheral vascular surgery are required to reduce costs to patients and healthcare providers. Bacteriophage (phage) therapy is a promising antimicrobial approach that has been recommended for consideration in antibiotic refractory cases. We systematically reviewed the clinical evidence for phage therapy in vascular surgery to support the unlicensed use of phage therapy and inform future research. Three electronic databases were searched for articles that reported primary data about human phage therapy for infections in cardiac or peripheral vascular surgery. Fourteen reports were eligible for inclusion, representing 40 patients, among which an estimated 70.3% of patients (n = 26/37) achieved clinical resolution. A further 10.8% (n = 4/37) of patients showed improvement and 18.9% (n = 7/37) showed no improvement. Six of the twelve reports that commented on the safety of phage therapy did not report adverse effects. No adverse effects documented in the remaining six reports were directly linked to phages but reflected the presence of manufacturing contaminants or release of bacterial debris following bacterial lysis. The reports identified by this review suggest that appropriately purified phages represent a safe and efficacious treatment option for infections in cardiac and peripheral vascular surgery.
RESUMO
INTRODUCTION: Necrotising soft tissue infections (NSTI) can threaten life and limb. Early identification and urgent surgical debridement are key for improved outcomes. NSTI can be insidious. Scoring systems, like the Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC), exist to aid diagnosis. People who inject drugs (PWID) are high risk for NSTI. This study aimed to assess the utility of the LRINEC in PWID with lower limb infections and develop a predictive nomogram. METHODS: A retrospective database of all hospital admissions due to limb-related complications secondary to injecting drug use between December 2011 and December 2020 was compiled through discharge codes and a prospectively maintained Vascular Surgery database. All lower limb infections were extracted from this database, dichotomised by NSTI and non-NSTI with the LRINEC applied. Specialty management times were evaluated. Statistical analyses involved: chi-square; Analysis of "variance"; Kaplan-Meier, and receiver operating characteristic curves. Nomograms were developed to facilitate diagnosis and predict survival. RESULTS: There were 557 admissions for 378 patients, with 124 (22.3%; 111 patients) NSTI. Time from admission to: theatre and computed tomography imaging respectively varied significantly between specialties ( P =0.001). Surgical specialties were faster than medical ( P =0.001). Vascular surgery received the most admissions and had the quickest time to theatre. During follow-up there were 79 (20.9%) deaths: 27 (24.3%) NSTI and 52 (19.5%) non-NSTI. LRINEC ≥6 had a positive predictive value of 33.3% and sensitivity of 74% for NSTI. LRINEC <6 had a negative predictive value of 90.7% and specificity of 63.2% for non-NSTI. Area under the curve was 0.697 (95% CI: 0.615-0.778). Nomogram models found age, C-reactive protein, and non-linear albumin to be significant predictors of NSTI, with age, white cell count, sodium, creatinine, C-reactive protein, and albumin being significant in predicting survival on discharge. CONCLUSION: There was reduced performance of the LRINEC in this PWID cohort. Diagnosis may be enhanced through use of this predictive nomogram.

BACKGROUND: and study aims: The Sheffield Gastrostomy Score (SGS) was devised to stratify patients by calculating their risk of mortality at 30 days following PEG insertion. The aim was to externally validate the SGS and identify any further predictors of 30-day mortality. PATIENTS AND METHODS: Retrospective review of all PEG insertions performed over a ten year period in our centre. All patients who had a new PEG inserted were identified and the SGS calculated. Additionally, demographic, indication for PEG insertion and other blood results were recorded. Receiver operating characteristic curves were calculated and subsequent univariate and multivariate analysis was performed to identify additional risk factors for 30 day mortality. RESULTS: The PEG database comprised 1373 patients, of which 808 were suitable for analysis. For each increasing SGS gradation mortality rose, with 4% of those scoring 0 compared to 50% scoring 3. An area under the ROC curve of 0.69 (95% confidence interval 0.64-0.74) indicated good discriminative capacity. Multivariate analysis demonstrated that age ≥60 years (OR = 2.1 p = 0.016), serum albumin concentrations of 25-34 g/l (OR = 2.5 p = 0.001) or <25 g/l (OR = 6.8 p < 0.001), C-Reactive Protein ≥10 mg/l (OR = 2.7 p = 0.009) and lymphocyte count of <1.5 × 109/l (OR = 2.0 p = 0.004) increased the odds of 30-day mortality, whilst referral for PEG placement whilst an inpatient decreased the risk of death (OR = 0.53 p = 0.005). CONCLUSIONS: The SGS displayed reasonable predictive ability but the area under the curve is not high enough for routine clinical use. Modelling of further predictors from a multicentre study could provide scope for updating the SGS potentially improving patient selection.
