Rapid Access From Primary Care to a Multidisciplinary Clinic at Tertiary Care Improves Clinical Outcomes for Patients With Diabetic Foot Ulcers: Results From Diabetic Foot in Primary and Tertiary (DEFINITE) Care's Lower Extremity Amputation Prevention Program (LEAPP) Clinic.

Diabetic Foot in Primary and Tertiary (DEFINITE) Care is an inter-institutional, multidisciplinary team (MDT) program for patients with diabetic foot ulcers (DFU) within a healthcare cluster in Singapore. This is one of our subgroup analyses within DEFINITE Care, assessing clinical outcomes of lower extremity amputation prevention program (LEAPP), a multidisciplinary diabetic foot clinic, and non-LEAPP patients within the program. From June 2020 to June 2022, 2798 patients within the DEFINITE cohort completed a minimum of 12-month follow up.

Snuffbox distal transradial access (dTRA) for arteriovenous fistuloplasty in Singapore: Going distal is safe.

Aim: Arteriovenous fistula (AVF) dysfunction resulting from stenosis or occlusion, is a prevalent issue in end-stage renal failure patients reliant on autogenous AVFs for dialysis. Recently, a distal transradial approach (dTRA) has emerged, offering advantages such as diminished access site complications, better patient comfort and reduced risk of radial artery occlusion. Our study seeks to assess the effectiveness, outcomes and complication rates of employing dTRA for arteriovenous fistuloplasty in Singaporean patients.

Multi-disciplinary diabetic limb salvage programme in octogenarians with diabetic foot ulcers is not futile: An observational study with historical controls.

This study evaluated the effectiveness of a multi-disciplinary diabetic limb salvage programme in improving clinical outcomes and optimising healthcare utilisation in 406 patients aged ≥80 years with diabetic foot ulcers (DFUs), compared to 2392 younger patients enrolled from June 2020 to June 2021 and against 1716 historical controls using one-to-one propensity score matching. Results showed that elderly programme patients had lower odds of amputation-free survival (odds ratio: 0.64, 95% CI: 0.

Risk Prediction of Diabetic Foot Amputation Using Machine Learning and Explainable Artificial Intelligence.

Risk prediction models can identify high-risk patients who can benefit from early intervention. Machine learning (ML) methods have shown promising utility in medical applications.

Utility of BeBack crossing catheter in fistula creation during percutaneous deep vein arterialization.

For patients with "no-option" chronic limb-threatening ischemia, a final attempt can be made for limb salvage in the form of percutaneous deep vein arterialization (pDVA). In the present study, we describe five cases of pDVA using a BeBack crossing catheter (Bentley InnoMed GmbH; previously, the GoBack crossing catheter; Upstream Peripheral Technologies). From November 2021 to July 2022, five patients underwent pDVA using the BeBack crossing catheter.

Introduction: Diabetes foot disease (DFD) contributes to poor quality of life, clinical and economic burden. Multidisciplinary diabetes foot teams provide prompt access to specialist teams thereby improving limb salvage. We present a 17-year review of an inpatient multidisciplinary clinical care path (MCCP) for DFD in Singapore.

Prospective study on the clinical and economic burden of venous leg ulcers in the tropics.

Objective: Venous leg ulcers (VLUs) are both chronic and recurrent. The treatment of such ulcers often require multiple outpatient visits and dressing changes. Several reports on the costs of treating such VLUs have been reported in the west.

A prospective study on the wound healing and quality of life outcomes of patients with venous leg ulcers in Singapore-Interim analysis at 6 month follow up.

Venous leg ulceration results in significant morbidity. However, the majority of studies conducted are on Western populations. This study aims to evaluate the wound healing and quality of life for patients with venous leg ulcers (VLUs) in a Southeast Asian population.

Diabetic foot in primary and tertiary (DEFINITE) Care: A health services innovation in coordination of diabetic foot ulcer (DFU) Care within a healthcare cluster - 18-month results from an observational population health cohort study.

Diabetic Foot in Primary and Tertiary (DEFINITE) Care is an inter-institutional and multi-disciplinary team (MDT) health systems innovation programme at a healthcare cluster in Singapore. We aim to achieve coordinated MDT care across primary and tertiary care for patients with diabetic foot ulcers (DFU), within our public healthcare cluster - an integrated network of seven primary care polyclinics and two acute care tertiary hospitals (1700-bed and 800-bed) with a total catchment population of 2.2 million residents.

Intravascular ultrasound correlation of unenhanced magnetic resonance venography in the context of pelvic deep venous disease.

Objective: In the present retrospective, assessor-blinded cross-sectional study, we compared the diagnostic efficacy of the relaxation-enhanced angiography without contrast and triggering (REACT) protocol for magnetic resonance venography (MRV) and intravascular ultrasound (IVUS).

Methods: All patients without prior lower limb vascular stenting who had undergone MRV with the REACT protocol and IVUS at our institution from January 2018 to May 2020 were included. The REACT protocol for MRV comprises three main phases: the adiabatic-based T2-preparation module, the non-volume-selective short tau inversion recovery pulse sequence, and the three-dimensional, modified two-point chemical-shift water-fat separated turbo-field echo pulse sequence.

Novel home use of mechanical negative pressure wound therapy in diabetic foot ulcers.

Objective: Mechanical negative pressure wound therapy is an ultraportable, light weight and disposable single-use device that has been shown to promote wound healing. This study evaluated home use of a mechanically powered negative pressure wound therapy (NPWT) in diabetic foot wounds.

Methods: Patients underwent revascularisation and/or debridement or amputation before starting mechanical NPWT.

Clinical and economic outcomes of a multidisciplinary team approach in a lower extremity amputation prevention programme for diabetic foot ulcer care in an Asian population: A case-control study.

Present guidelines recommend a multidisciplinary team (MDT) approach to diabetic foot ulcer (DFU) care, but relevant data from Asia are lacking. We aim to evaluate the clinical and economic outcomes of an MDT approach in a lower extremity amputation prevention programme (LEAPP) for DFU care in an Asian population. We performed a case-control study of 84 patients with DFU between January 2017 and October 2017 (retrospective control) vs 117 patients with DFU between December 2017 and July 2018 (prospective LEAPP cohort).

Clinical validation of a machine-learning-based handheld 3-dimensional infrared wound imaging device in venous leg ulcers.

Clinical validation of an artificial intelligence-enabled wound imaging mobile application in diabetic foot ulcers.

There is a lifetime risk of 15% to 25% of development of diabetic foot ulcers (DFUs) in patients with diabetes mellitus. DFUs need to be followed up on and assessed for development of complications and/or resolution, which was traditionally performed using manual measurement. Our study aims to compare the intra- and inter-rater reliability of an artificial intelligence-enabled wound imaging mobile application (CARES4WOUNDS [C4W] system, Tetsuyu, Singapore) with traditional measurement.

Ilio-Femoral Deep Vein Thrombosis Secondary to May-Thurner Syndrome With Ipsilateral Lower Limb Arterio-Venous Graft In-Situ.

Ilio-femoral deep vein thrombosis (DVT) is rare in patients with lower limb arterio-venous grafts due to a state of high blood flow. May-Thurner syndrome (MTS) is an anomaly where the left common iliac vein is compressed by the right common iliac artery. We present a rare case of ilio-femoral deep vein thrombosis in a patient with May-Thurner Syndrome and an underlying arteriovenous graft in-situ who presented with acute lower limb swelling.
