    Abstract In recent years, high-throughput technologies have facilitated the widespread use of metabolomics to identify biomarkers and targets for oral squamous cell carcinoma (OSCC). As a result, the primary goal of this systematic review is to identify and evaluate metabolite biomarkers and their pathways for OSCC that featured consistently across studies despite methodological variations. Six electronic databases (Medline, Cochrane, Web of Science, CINAHL, ProQuest, and Embase) were reviewed for the longitudinal studies involving OSCC patients and metabolic marker analysis (in accordance with PRISMA 2020). The studies included ranged from the inception of metabolomics in OSCC (i.e., 1 January 2007) to 30 April 2023. The included studies were then assessed for their quality using the modified version of NIH quality assessment tool and QUADOMICS. Thirteen studies were included after screening 2285 studies. The majority of the studies were from South Asian regions, and metabolites were most frequently derived from saliva. Amino acids accounted for more than quarter of the detected metabolites, with glutamate and methionine being the most prominent. The top dysregulated metabolites indicated dysregulation of six significantly enriched pathways including aminoacyl-tRNA biosynthesis, glutathione metabolism and arginine biosynthesis with the false discovery rate (FDR) <0.05. Finally, this review highlights the potential of metabolomics for early diagnosis and therapeutic targeting of OSCC. However, larger studies and standardized protocols are needed to validate these findings and make them a clinical reality.

    Abstract Background: Obesity is increasing in prevalence globally and within the cohort of vascular surgical patients, leading to poorer outcomes. There are few data on endoleak as a complication of AAA surgery in obese patients. The aim of this study was to use large scale registry data from the Global Registry for Endovascular Aortic Treatment (GREAT) to interrogate any relationship between obesity and endoleak following endovascular aneurysm repair (EVAR) using a Gore Excluder device (W. L. Gore & Associates, Newark, DE, USA), in order to guide treatment recommendations in the future.
    Methods: A retrospective review of the GREAT Registry was carried out and patients who were recorded as having a postoperative endoleak requiring intervention were included. Patient demographics including Body Mass Index (BMI), aneurysm parameters and on- or off-instructions for use (IFU) were recorded. Ruptured AAA were excluded.
    Results: Data were obtained for 3326 patients with an operation date between August 25, 2010 and September 22, 2019. Obese patients were significantly less likely to have a Type 1 endoleak (Fisher's Exact P value=0.006), and the association was maintained in a multiple logistic regression model which controlled for age, gender, neck angulation and off IFU device use (OR=0.33, P=0.01).
    Conclusions: Among AAA patients treated with a Gore Excluder device (W. L. Gore & Associates), a higher BMI category was associated with a lower risk of Type 1 endoleak requiring reintervention. Further work needs to be carried out to assess our findings in other patient cohorts.

    Abstract Monkeypox is a viral zoonotic infection which has rapidly increased in incidence and spread globally since May 2022. There have been reports of rectal complications of monkeypox but so far these are not well not understood. Here, we describe a case of rectal pain in HIV-positive man with confirmed monkeypox. MRI on day 5 of hospital admission revealed proctitis with localised perforation. The patient was treated with tecovirimat, antibiotics, analgesia and laxatives and improved without requiring surgical intervention. All patients presenting with new rectal symptoms and deemed high-risk for monkeypox should be isolated and screened for the disease, and appropriate personal protective equipment should be worn by healthcare professionals caring for them. Clinicians should have a low threshold for cross-sectional imaging in patients with confirmed or suspected monkeypox who experience persistent and severe rectal symptoms or who become systemically unwell to investigate for complications such as perforation and abscess formation. The vast majority of monkeypox cases do not require antibiotics and their use should be reserved for patients who show signs of secondary bacterial infection or sepsis.

    Abstract Background: Vascular micro-channels within chronic total occlusions (CTO) have been identified in histopathology and animal studies. They have been proposed as a potential path for achieving endovascular crossing via the lumen. There are currently no noninvasive means of imaging these structures. The aim of this study was to investigate whether contrast-enhanced ultrasound (CEUS) examination can identify micro-channels within CTO in humans.
    Methods: CTO within the femoropopliteal arteries were imaged with CEUS examination in 38 patients. Segments containing micro-channels were identified and their length measured. The proportion of occlusion length containing micro-channels was assessed for each case. Micro-channel appearances including linear or tortuous configuration, crossing of occlusion caps, and connections to vasa vasorum were recorded.
    Results: The median CTO length was 17.0 cm (interquartile range [IQR], 6.9-27.9 cm) and median age of CTO was 12 months (IQR, 6-16 months). Micro-channels were identified in 92.1% of cases (35/38). The median length within a lesion containing micro-channels was 6.4 cm (IQR, 2.4-14.3 cm) and median proportion of CTO containing micro-channels was 47.9% (IQR, 1.7%-28.5%). A linear micro-channel configuration was seen in 84.2% of cases and a tortuous configuration was seen in 57.9% of cases. Micro-channel connections through the cap were seen in 50% (19/38 cases) and connections to the vasa vasorum in 71.1% (27/38 cases). No association was found between the proportion of each lesion containing micro-channels and CTO age, lesion length or calcification severity. There were no adverse effects related to contrast use.
    Conclusions: CEUS can be used to detect micro-channels in CTO in human femoropopliteal arteries. This imaging technique is safe and minimally invasive and may represent a practical method for selection of occlusion crossing method. Further work is required to determine whether identification of micro-channels can be used to improve treatment decision-making and provide a better understanding of the natural history of femoropopliteal CTO.

    Abstract Deep venous arterialization is increasingly being considered for the management of patients with "no option chronic limb threatening ischemia" (CLTI) who would otherwise require a major limb amputation. WavelinQ (Becton Dickinson) is a new technology increasing in popularity for its role in the formation of endovascular arteriovenous fistulas but might well have applications in other areas of vascular surgery. We present a novel approach to deep venous arterialization using WavelinQ arteriovenous fistula technology for a patient with nonreconstructable chronic limb threatening ischemia experiencing both rest pain and forefoot gangrene. The patient's early tissue loss healed and he remained symptom free at 6 months after the intervention.

    Abstract Context: Atherosclerosis is a systemic pro-inflammatory and pro-oxidative disease, accounting for approximately a third of deaths globally. It has been proposed that omega-3s, through their antioxidant and anti-inflammatory properties, mitigate atherosclerotic disease progression. However, due to the systemic pro-inflammatory and pro-oxidative state of atherosclerosis, it is proposed that patients with atherosclerotic disease may have higher omega-3 requirements than the average requirement, due to increased nutrient utilization in anti-inflammatory and anti-oxidant processes.
    Objective: The aim of this review was to determine what dose and duration of omega-3 supplementation is required to reach a therapeutic blood level of omega-3s (eicosapentaenoic acid ≥150 µg/mL or omega-3 index ≥8%) in people with chronic atherosclerotic disease.
    Data sources: This systematic review comprehensively searched MEDLINE, Emcare, Scopus, and CINAHL using key search terms for atherosclerotic disease, omega-3, supplementation, and blood levels of omega-3s.
    Data extraction: Two reviewers independently screened 529 randomized controlled trials (RCTs) supplementing omega-3s in patients with chronic atherosclerotic disease.
    Data analysis: In total, 25 journal articles from 17 original RCTs were included and assessed quantitatively. Supplementation at 1.8 g to 3.4 g per day for a 3-month-6-month duration, and at 4.4 g and above for as little as 1 month-6 months were identified as the most effective dosage ranges for increasing blood levels of omega-3s to therapeutic levels in people with atherosclerotic disease.
    Conclusions: Consideration should be given to routine omega-3 supplementation and to increasing the omega-3 dietary recommendations and upper limits of daily intake to improve clinical outcomes and reduce the risk of cardiac mortality in this population.

    Abstract Purpose: To compare the clinical outcomes of common femoral artery (CFA) atherosclerotic disease treated with either surgical endarterectomy or an interwoven nitinol wire stent system.
    Materials and methods: A retrospective review was conducted of all patients with chronic, de novo atherosclerotic CFA disease treated with surgical endarterectomy (CFAE) or stent placement between July 2019 and March 2022. Outcome measures assessed up to 12 months after procedure included clinical improvement, primary restenosis, target vessel revascularization (TVR), major adverse limb events (MALEs), and all-cause mortality.
    Results: Thirty-nine stents were deployed in 33 patients, and 56 CFAEs were performed in 55 patients. No differences were noted in the rate of primary patency (95.5% vs 94.4%, P = .618), TVR (2.9% vs 1.8%, P = .777), MALE (5.1% vs 5.4%, P = .949), and all-cause mortality (14.1% vs 3.6%, P = .076) between the stent and CFAE groups up to 12 months after procedure. There was greater improvement in median clinical severity in the stent group than in the CFAE group (Rutherford score change of 3.0 vs 1.5, P = .013). The median length of stay was less for the stent group (3 vs 7 days, P = .002), and there was a lower likelihood of severe or disabling adverse events in the stent group (0 vs 9 cases, P = .010).
    Conclusions: Patients treated with an interwoven nitinol wire stent had patency rates comparable to those treated with CFAE while having a lower incidence of severe adverse events and a shorter length of hospital stay than those who underwent CFAE.

    Abstract Identifying nutritional deficits and implementing appropriate interventions in patients requiring vascular surgery is challenging due to the paucity of appropriate screening and assessment tools in this group. This retrospective study aimed to determine the validity of the Global Leadership Initiative on Malnutrition (GLIM) in identifying protein-energy malnutrition (PEM) in inpatients admitted to a vascular surgery unit, using the PG-SGA as the comparator. Diagnostic accuracy and consistency were determined between the GLIM and the Patient-Generated Subjective Global Assessment (PG-SGA) global rating. The GLIM determination was made retrospectively using the relevant parameters collected at baseline in the original study. Two hundred and twenty-four (70·1 % male) participants were included. The prevalence of PEM was 28·6 % on GLIM and 17 % via the PG-SGA. Compared with the PG-SGA, the GLIM achieved sensitivity of 73·7 % and specificity of 80·6 %; however positive predictive value was 43·7 % indicating that the GLIM over-diagnosed malnutrition compared with the PG-SGA. Kappa reached 0·427 indicating moderate diagnostic consistency. Due to the absence of an ideal instrument and the complexity of malnutrition often seen in this group which extends beyond PEM to significant micronutrient deficiencies, further work is required to determine the most appropriate instrument in this patient group, and how micronutrient status can also be included in the overall assessment given the critical role of micronutrients in this group.
