• Surgical Site Infection in Major Lower Limb Amputation (SIMBA): an international multicentre audit: baseline unit survey

  Journal of Vascular Societies Great Britain and Ireland · 2025-08-18

  articleOpen access

  Introduction: Surgical site infection (SSI) is common after major lower limb amputation (MLLA) and is associated with significant morbidity and mortality. National and international guidelines and a best practice pathway aim to optimise care and prevent complications, but adherence is unknown. Methods: Surgical Site Infection in Major Lower Limb Amputation (SIMBA) is an international, prospective, collaborative audit which compared current practice against national and international recommendations and evaluated equipoise regarding best practice. Each participating centre completed a baseline unit survey containing Likert scale questions regarding local MLLA pathways. Responses were compared with the Vascular Society of Great Britain and Ireland’s best practice pathway, National Institute for Health and Care Excellence (NICE), Society of Vascular Surgery’s Practice management guide and the European Journal of Vascular Surgery’s Global Vascular Guidelines on the Management of Chronic Limb-Threatening Ischaemia guidelines. Results: Forty centres (30 UK, 7 Europe, 2 Australasia and 1 Asia) completed the survey, yielding a response rate of 87% (40/46). MLLA was performed by vascular surgeons in all centres, with additional specialities also undertaking MLLA surgery including orthopaedic (n=10), plastic (n=4) and general surgery (n=3). Induction antibiotic prophylaxis was given in 32 (82.1%) of the centres. Prophylactic postoperative antibiotics were ‘commonly’ or ‘always’ given in 24 (61.5%) of the centres, typically comprising a 5-day intravenous course. Incise drapes were infrequently used (used ‘never’ for iodophor (39.5%, n=15) and non-iodophor (44.7%, n=17) containing drapes). Routine follow-up was conducted in 27 centres (69.2%) and preoperative vascular imaging was ‘commonly’ or ‘always’ performed in 37 centres (92.5%). Preoperative assessment by physiotherapists and/or occupational therapists and diabetic specialists occurred ‘commonly’ or ‘always’ in 32 (82.1%) and 27 (71.1%) centres, respectively. Dietetic and psychological assessment only occurred ‘commonly’ or ‘always’ in 8 (21.6%) and 9 (25%) centres, respectively. Conclusions: This audit highlights the variability in practice, underscoring the need for consensus on best practice. Future studies should focus on generating high quality evidence to refine recommendations and reinforce adherence to guidelines to reduce SSI and improve outcomes after MLLA.

• Some Memories of Tinsley Oden and the Extension of the Twist-Kirchhoff Elements to the Buckling Analysis of Plates

  Computing in Science & Engineering · 2025-09-23

  article1st authorCorresponding

  The senior author begins with recollections of his long friendship and professional relationship with Tinsley Oden. Then we discuss some recent developments in the twist-Kirchhoff theory of plates. More specifically, we extend the first two members of the twist-Kirchhoff family of arbitrary quadrilateral elements to the linear buckling analysis of plates. While standard polynomial <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">C</i><sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup>-continuous approximation functions are adopted for the transverse displacements, Raviart-Thomas vector-field approximations are considered for the rotations. Continuity of the normal components of the rotation vector across mesh edges is preserved by using the Piola transformation to map the rotations from the parent domain to the physical domain. The elements possess a unique combination of efficiency and robustness in that minimal quadrature rules are sufficient to guarantee stability without rank deficiency. We numerically study the convergence and accuracy of the elements on square, circular and skew plate buckling problems.

• Phase-Field/Discontinuity Capturing operator for direct van der Waals simulation (DVS)

  ArXiv.org · 2025-10-24

  preprintOpen access

  Discontinuity capturing (DC) operators are commonly employed to numerically solve problems involving sharp gradients in the solution. Despite their success, the application of DC operators to the direct van der Waals simulation (DVS) remains challenging. The DVS framework models non-equilibrium phase transitions by admitting interfacial regions in which the derivative of pressure with respect to density is negative. In these regions, we demonstrate that classical DC operators may violate the free energy dissipation law and produce unphysical wave structures. To address this limitation, we propose the phase-field/discontinuity capturing (PF/DC) operator. Numerical results show that PF/DC yields stable and accurate solutions in both bulk fluids and interfacial regions. Finally, we apply the proposed method to simulate cavitating flow over a three-dimensional bluff body, obtaining excellent agreement with experimental data and significant improvements over results produced using classical DC operators.
