Kidney transplant recipients are at increased risk of surgical site infections (SSIs) due to procedural complexity and immunosuppression. This retrospective single-centre study examines the influence of BMI on SSI risk and identifies common pathogens. A total of 230 renal transplant patients were included in this analysis 2017 and 2019. All patients received a cephalosporin for prophylaxis, and wound swabs were taken from those who developed SSIs. SSIs occurred in 45 patients (19.6%) and were not significantly associated with age, sex or donor type. The most common organisms were coagulase-negative staphylococci (26.7%), Staphylococcus epidermidis (24.4%), Enterococcus faecalis (22.2%) and Candida albicans (22.2%). SSIs were significantly linked to surgical revision (p < 0.001) and higher BMI (p = 0.027). A BMI ≥ 28.1 was associated with threefold higher odds of SSIs (OR = 3.0; p = 0.001). Each one-unit increase in BMI was associated with a 7.2% increase in the odds of SSI occurrence (OR = 1.072; p = 0.020). Staphylococcus (p = 0.019) and Enterococcus (p = 0.048) infections were more common in patients with BMI > 28.1. Therefore, SSIs are a frequent complication posttransplant and are strongly associated with high BMI. Standard antibiotic regimens may not cover all relevant pathogens in obese patients, underscoring the need for tailored prophylactic strategies.
Keloids are chronic fibroproliferative skin disorders with high recurrence rates and limited treatment options, yet reliable diagnostic biomarkers are lacking. Current classification systems rely heavily on clinical observation, underscoring the need for objective, noninvasive tools. In this exploratory study, serum-based 1H nuclear magnetic resonance (NMR) measurement combined with short-time Fourier transform (STFT) for time-frequency analysis was performed, followed by principal component analysis (PCA), to investigate potential patient subgroups. Serum samples from 29 patients were analysed and PC1 scores suggested two potential patient subgroups. Retrospective analysis showed that these subgroups differed primarily in keloid aetiology: one group predominantly included cases arising from unclear or minimal causes (e.g., acne, folliculitis), whereas the other comprised cases following clear traumatic events (e.g., surgery). Although most clinical variables showed no significant differences, significant differences in aetiology and Japan Scar Workshop Scar Scale (JSS) scores support the biological relevance of this separation of subgroups. These findings suggest that the time-frequency features of NMR signals from serum samples capture systemic characteristics associated with keloid pathophysiology. If validated in larger cohorts, this approach may serve as a noninvasive adjunct to clinical assessment and lay the foundation for objective patient stratification and precision-guided treatment strategies.
The number of patients requiring wound care is increasing, placing a burden on healthcare institutions and clinicians. While negative pressure wound therapy (NPWT) use has become increasingly common, Middle East-specific wound care guidelines are limited. An in-person meeting was held in Dubai with 15 wound care experts to develop guidelines for NPWT and NPWT with instillation and dwell (NPWTi-d) use for the Middle East. A literature search was performed using PubMed, Science Direct and Cochrane Reviews. Prior to the meeting, panel members reviewed literature and existing guidelines on NPWT and/or NPWTi-d use. A wound management treatment algorithm was created. Patient and wound assessment at presentation and throughout the treatment plan was recommended. Primary closure was recommended for simple wounds, and NPWT use was suggested for complex wounds requiring wound bed preparation. NPWTi-d use was advised when wound cleansing is required, if the patient is unsuitable for surgical debridement, or if surgical debridement is delayed. When NPWTi-d is unavailable, panel members recommended NPWT. Panel members recommended NPWT for wound bed preparation and NPWTi-d when wound cleansing is needed. These recommendations provide general guidance for NPWT and NPWTi-d use and should be updated as more clinical evidence becomes available.
