Objectives The aim of this study was to retrospectively review the effectiveness of negative pressure wound therapy (NPWT) in sternal wound healing with the use of the validated Bates-Jensen Wound Assessment Tool (BWAT), and explore the role of NPWT over sternal wounds and future treatment pathways. Methods Data was gathered from patients' medical records and the institution's database clinical management system. Seventeen subjects, who had undergone cardiothoracic surgeries and subsequently consulted the wound care team in one year were reviewed. Fourteen of them were included in the analysis. Healing improvement of each sternal wound under continuous NPWT and continuous conventional dressings was studied. In total, 23 continuous NPWT and 13 conventional dressing episodes were analysed with the BWAT. Results Among conventional dressing episodes, sternal wound improvement was 2.5–3% over 10 days to 3.5 weeks, whereas 4–5% sternal healing was achieved in 5 days to 2 weeks with sternal wire presence. Better healing at 11% in 1 week by conventional dressing was attained after sternal wire removal. In NPWT episodes, 8–29%, 13–24%, and 15–46% of healing was observed in 2 weeks, 3.5 to 5 weeks and 6 to 7 weeks, respectively. Only 39% wound healing was acquired at the 13th week of NPWT in one subject. With sternal wire present, 6%–29% wound healing progress was achieved by NPWT in 1–4 weeks, and 16–23% wound improvement in 2 to 4.5 weeks by NWPT after further surgical debridement. After sternal wire removal, 6–34% sternal wound healing occurred by continuous NPWT for 1–2 weeks, and maximum healing at 46% after 2.5 weeks of NPWT were observed. Conclusions Better wound healing was achieved in the NPWT group in comparison to conventional dressings alone. However, suboptimal sternal wound healing by NPWT alone was observed. Removal of sternal wire may improve the effectiveness of NPWT. Successful tertiary closure after NPWT among subjects supports the important bridging role of NPWT in sternal wound healing. Factors causing stagnant sternal wound healing by NPWT alone are discussed.

Patients With Diabetes

Diabetic foot ulcer (DF) is a chronic complication of diabetes mellitus (DM), which impact on the morbidity, mortality and quality of patients’ lives.Of those patients with diabetes mellitus, approximately 15% to 25% developed to the foot ulcer. Beside has the infection and debridement of devitalized tissue downloading; the moisture imbalance becomes the factors of recalcitrant to healing. Moist wound healing is often contraindicated to the non-healable wounds. While wound care involves the debridement, bacterial reduction, and moisture balance in order to achieve the good granulation of the tissue development and adequate blood supply.

Purpose:To evaluate an evidence-based wound protocol for intravenous extravasation injuries in neonates.Sample:Nine newborns with intravenous extravasation injuries. Birth weight: 582–4,404 gm, gestational age: 24–40 weeks.Results:Five wounds were colonized with coagulase-negative Staphylococcus species, two with diphtheroids, three with Enterococcus. There was no evidence of wound infection or systemic infection. Rates of wound healing ranged from one to six weeks.

Mesenchymal stromal cells and the derived conditioned media represent an area of tremendous medical interest and, among other clinical applications, are currently being extensively explored for wound healing. The aim of this study was to comparatively evaluate the wound healing potential of xeno-free human umbilical cord-derived mesenchymal stromal cells (MSCs) and the conditioned media (CM) in a full-thickness excision wound model in rats. The evaluation parameters included rate of wound healing, serum cytokine analyses, collagen content, histopathology, and hyperspectral imaging as an independent qualitative and quantitative tool. Both the cell-based and cell-free approaches scored better in lower inflammation, as evidenced in lower IL-10 and stable IL-6 levels, and improved rate of wound healing (<i>p</i> &#x3c; 0.0001). More importantly, no adverse reaction or rejection was observed although human MSCs and CM were used in a xenogeneic model. The presence of hFGF, hHGF, hGCSF, hIL-1Ra, hVEGF, and hIL-6 in the secretome may elucidate the regenerative potential of the xeno-free cell-based and cell-free approaches which have translational value for advanced wound care. The results revealed the therapeutic potential of both the cell-based and cell-free approaches for wound healing.

Viable Approach

: Chronic wounds remain a significant public problem and the development of wound treatments has been a research focus for the past few decades. Despite advances in the products derived from endogenous substances involved in a wound healing process (e.g. growth factors, stem cells, and extracellular matrix), effective and safe wound therapeutics are still limited. There is an unmet need to develop new therapeutics. Various new pathways and targets have been identified and could become a molecular target in designing novel wound agents. Importantly, many existing drugs that target these newly identified pathways could be repositioned for wound therapy, which will facilitate fast translation of research findings to clinical applications. This review discusses the newly identified pathways/targets and their potential uses in the development of wound therapeutics. Some herbs and amphibian skins have been traditionally used for wound repairs and their active ingredients have been found to act in these new pathways. Hence, screening these natural products for novel wound therapeutics remains a viable approach. The outcomes of wound care using natural wound therapeutics could be improved if we can better understand their cellular and molecular mechanisms and fabricate them in appropriate formulations, such as using novel wound dressings and nano-engineered materials. Therefore, we also provide an update on the advances in the wound therapeutics from natural sources. Overall, this review offers new insights into novel wound therapeutics.

Aim: Hard-to-heal diabetic foot ulcers (DFUs) may increase the risk of amputation. This study reports the positive influence of hyperbaric oxygen therapy (HBOT) on hard-to-heal DFUs involving underlying bone. Method: A single-centre, retrospective cohort study reporting the results of HBOT and wound care on hard-to-heal University of Texas grade 3 DFUs (i.e., involving underlying bone) between 2013 and 2019. Outcome measures were primarily (near-) complete wound healing (i.e., ≥80% ulcer surface area reduction) and amputation rate (minor or major), and secondarily the number of hyperbaric sessions and improvement in quality of life (QoL) and pain score. Results: The study included 206 patients, of whom 74 (36%) achieved complete wound healing, and 75 (36%) near-complete healing. Amputations were performed in 27 patients (13%): 12 (6%) minor and 15 (7%) major. The median number of HBOT sessions was 42. Participants who achieved complete healing received a median of 43 sessions, compared with 10 for those who required major amputation. Patients with at least 30 sessions were less likely to undergo amputation (odds ratio: 0.08; 95% confidence interval (CI): 0.03–0.21). Mean QoL increased by 7.6 points (95%CI: 3.9–11.3; p<0.01) and median pain score fell from 3 to 1 (0–3) (p<0.01). Conclusions: The addition of HBOT to standard wound care may lead to a decreased amputation risk, improved wound healing and increased QoL for people with a University of Texas grade 3 DFU. An adequate number of HBOT sessions is required to achieve optimal clinical results. Objective selection criteria and shared decision-making are suggested to improve dropout rates.
