Chronic and non-healing wounds are a global health issue with limited effective treatments. Wound care costs continue to rise, highlighting the need for new therapies. Medicinal plants, particularly African species, show promise for enhancing wound healing. This review analysed 93 studies and identified 37 relevant to wound healing, covering 39 plant species. Ten species were identified for their rich phytochemical content, specifically flavonoids, terpenoids, and alkaloids (plant-derived compounds). These compounds act synergistically, enhancing the wound healing process at each stage. Flavonoids reduce inflammation and support tissue turnover, while terpenoids enhance collagen production and wound closure. Alkaloids offer antimicrobial benefits and support wound contraction. Notable plants include Ageratum conyzoides and Aspilia africana (Asteraceae family); promoting haemostasis by lowering plasma fibrinogen and enhancing platelet-derived growth factors; Withania somnifera (Solanaceae); and Entada africana (Fabaceae), effectively regulating inflammation. In the proliferative phase, Ocimum gratissimum (Lamiaceae), Calendula officinalis (Asteraceae), and Centella asiatica (Apiaceae) although C. officinalis is native to Southern Europe, and C. asiatica an Asian-native; they are widely used in African traditional medicine and included here for their relevance in African wound healing practices; Justicia flava (Acanthaceae), Alternanthera sessilis (Amaranthaceae), and Acalypha indica (Euphorbiaceae); play key roles in enhancing collagen production, angiogenesis, and re-epithelialisation. This comprehensive analysis highlights the role of African medicinal plants in wound healing and their potential to improve wound care therapy.
This initiative utilised knowledge translation (KT) strategies, including digital storytelling (DST) as both a narrative and educational tool, to amplify voices and support trauma-informed healing for individuals living with chronic wounds. A multi-method KT approach was employed, involving: (1) patient DST; (2) a national Patient Journey conference; (3) webinars and conference sessions; (4) a social media campaign; (5) infographics and supplements and (6) an open-access digital library. Since its launch in November 2021, the initiative has garnered significant engagement. Twenty-five patients and care partners across Canada shared their wound care journeys. In June 2022, 191 patients, advocates, policymakers and healthcare providers attended the inaugural virtual Patient Journey. Additionally, 102 participants joined three Patient Journey events between June and October 2024. Patient stories received 23 012 views, and the social media campaign and infographics reached over 900 healthcare professionals, policymakers and advocates across Canada. The initiative raised awareness of the challenges faced by individuals living with wounds. Storytellers described grief, frustration and confusion, underscoring the need for person-centred wound care, timely specialised services and better healthcare navigation. Their experiences revealed care gaps, highlighting the urgent need for systemic change to promote equity and inclusivity in wound care.
Remote assessment of surgical site infection(SSI) lacks sensitivity for the diagnosis of SSI, but current evidence has not evaluated whether a combination of photographs and questionnaires improves diagnostic accuracy. This study aims to develop a remote diagnostic measure to identify SSI. A two-phase mixed methods study was conducted. In phase I, five clinicians reviewed the Bluebelle wound healing questionnaire(WHQ) on a five-point Likert scale of agreement for inclusion in a remote measure. Discussion generated a hypothesis as to which items should be included. In phase II, a cohort study, whereby clinicians evaluated patient's wound images and patients completed the WHQ, were reviewed for scale structure. Principal component analysis (PCA) with scree plot examination and maximum likelihood of estimation (MLE) for one, two and three factors were evaluated. Internal consistency was assessed with Cronbach's α. Phase I: hypothesis generation estimated a measure containing between 10 and 12 items would include all relevant items without ambiguity or redundancy. Phase II: a combined sample of 570 responses provided clinician reviewed images and patient responses. PCA suggested that a 12-item measure with a combined variance of 60.2% would have the best model fit. Cronbach's α was high at 0.841. One included item was highlighted as potentially ambiguous in phase I (wound pain), providing an additional model with this removed. MLE for one, two and three factors suggested measures with 8, 10 and 11 items, respectively. Total variances were low at 29.7%, 39.8% and 41.4% and Cronbach's α were high at 0.838, 0.827 and 0.823, respectively. Three potential models for a remote diagnostic measure were identified. Each is shorter than alternative available measures, which have not been designed for combined use, ensuring this is easy to use. Further evaluation for reliability and diagnostic accuracy is needed to validate a final measure that can be implemented in clinical practice.
This study set forth to investigate the efficacy of Quality and Quantity mononuclear cells (QQMNCs) for promoting wound healing and limb salvage in a severe ischemic wound model using diabetic mice. Female BALB/c nude mice induced with diabetes were used to create ischemic limb models in a controlled experimental design. Intramuscular injections of human QQMNCs were compared to phosphate-buffered saline (PBS) and peripheral blood mononuclear cells (PBMNCs) relative to their effects on wound healing and limb salvage. In vitro analysis demonstrated that the QQMNC group had significantly higher median percentages of CD34+ cells, CD34+CD133+ cells, CD206+ cells, and FOXP3+ cells compared to the PBMNC group (all p < 0.05), which suggests an enhanced regenerative and immunomodulatory profile. Kaplan–Meier survival analysis showed a significantly higher number of completely healed wounds in the QQMNC group than in the PBMNC group (p = 0.044). The histological evaluation showed that the QQMNC group had a significantly thinner epithelial thickness than the PBMNC (p = 0.032) and PBS groups (p = 0.002), and a significantly greater T cell density than the PBS group (p = 0.033), which suggests more efficient tissue repair. Moreover, the QQMNC group exhibited the highest percentage of minor tissue loss (57% for forefoot and toe gangrene), and the lowest incidence of severe limb loss (0% for lower leg gangrene). The findings of this study highlight the effectiveness of QQMNCs for promoting wound healing and limb salvage in diabetic ischemic animal model; however, clinical trials are needed to further assess their efficacy in this clinical context.
