Abstract
Negative pressure injury is one of the auxiliary methods of treating diabetes foot ulcers. It has been shown to be superior to conventional techniques in randomized controlled trials (RCTs). Nevertheless, the results of observational research are still scarce. A systematic review of RCTs and observations was carried out to evaluate the effectiveness and security of negative pressure wound therapy (NPWT) treatment for diabetes foot ulcers. Three English e-databases have been found for NPWT research. The meta-analyses of the comparative studies provided point estimates of results. Intermediate results were given as median and binary values were given in the form of odds ratios (OR). Seventeen trials, 13 RCTs and four randomized, controlled trials were found in the survey. Of these, 831 were treated with NPWT, 834 were treated with standard therapy. A total of 14 studies have been conducted to investigate the influence of NPWT on the healing of diabetic foot ulcers(DFU). In the study, NPWT was shown to speed up the healing of the wound in DFU patients(OR, 2.57; 95% CI, 1.72, 3.85 p < 0.0001). A subgroup analysis showed that NPWT was associated with an acceleration of the wound healing rate in 10 RCT trials (OR, 2.48; 95% CI, 1.58, 3.89 p < 0.001). In the four nRCT trials, NPWT was also shown to speed up the healing of the wound(OR, 2.95; 95% CI, 1.03, 8.42 p = 0.04). In 11 studies, the influence of NPWT on amputations of diabetes mellitus (DM) foot ulcers was investigated. The results showed that NPWT was associated with a reduction in amputations (OR, 0.53; 95% CI, 0.37, 0.74 p = 0.0002).In a subgroup of RCT trials, nine RCT trials showed a reduction in amputations(OR, 0.61; 95% CI, 0.43, 0.87 p = 0.007). In both nRCT trials, NPWT also showed a reduction in amputations (OR, 0.03; 95% CI, 0.00, 0.24 p = 0.001). Generally speaking, NPWT can help to heal the wound and lower the risk of amputations in people with diabetes. The subgroup analysis showed similar results for the RCT and non-RCT trials. NPWT can be used to treat diabetes foot ulcers caused by diabetes.

Abstract
Nontuberculous mycobacteria (NTM) skin infections remain therapeutically challenging. Given the diversity in infections, host responses, and antimicrobials, clinical guidelines are often built on case series and observational studies. In this commentary, we respond to a paper by Stemkens et al. that introduces an emerging strategy: adjunctive negative pressure wound therapy with instillation and dwell time combined with topical antibiotics for refractory NTM skin and soft tissue infections. We delve into the primary considerations surrounding this innovative approach.

Economic model to estimate cost of negative pressure wound therapy with instillation vs control therapies for hospitalised patients in the United States, Germany, and United Kingdom. Int Wound J 2021; 19:888-894.

Abstract
An economic model was developed to estimate the cost of negative pressure wound therapy with instillation and dwelling of a topical wound solution vs control therapies. Economic model inputs were means derived from the results of a recently published systematic review and meta‐analysis of 13 comparative studies of negative pressure wound therapy with instillation. Means across studies comprising complex acute and chronic wounds for negative pressure wound therapy‐instillation vs control (negative pressure wound therapy without instillation, gauze dressings, or gentamicin polymethylmethacrylate beads) groups were 1.77 vs 2.69 operating room visits (P = .008) and 9.88 vs 21.80 therapy days (P = .02), respectively. These inputs plus hospital cost data were used to model costs for the United States, Germany, and the United Kingdom. For the United States, Germany, and United Kingdom, respectively, economic model estimates of total potential per patient savings were $33 338, €8467, and £5626 for negative pressure wound therapy‐instillation group vs control, based on assumed number of OR visits during therapy, cost of therapy system, and length of therapy. Model results showed an overall potential cost‐savings with negative pressure wound therapy‐instillation vs control, based on fewer OR visits and shorter therapy duration as reported in the published systematic review and meta‐analysis.

Abstract
BACKGROUND Large randomized controlled trials that evaluate the effects of negative-pressure wound therapy with instillation of a topical solution and dwell time (NPWTi-d) are lacking. There is a need to synthesize existing data across multiple studies to provide a more precise estimate of the clinical effects of NPWTi-d. METHODS A systematic literature review and a meta-analysis of comparative studies were performed to determine the effects of NPWTi-d versus control therapy in the adjunctive management of complex wounds. Weighted standardized mean difference or odds ratios and 95% confidence intervals were calculated to pool study and control group results in each publication for analysis. RESULTS Thirteen studies comprising 720 patients were included in the analysis. Significantly fewer surgical debridements were performed in NPWTi-d patients versus control patients (P = 0.01). Wounds in the NPWTi-d group were ready for closure faster than control wounds (P = 0.03). The odds of reducing bacterial count from baseline in the NPWTi-d group was 4.4 times greater than control group wounds (P = 0.003), and percent reduction of bacterial count in NPWTi-d wounds was evident in all studies that captured that endpoint. There was a significantly shorter length of therapy in NPWTi-d patients versus control patients (P = 0.03). Wounds in NPWTi-d group were 2.39 times more likely to close than control group wounds (P = 0.01). Length of hospital stay was not significantly reduced for NPWTi-d patients compared with that for control patients (P = 0.06). CONCLUSION Results of this meta-analysis show a positive effect with use of NPWTi-d in various wound types.

Abstract
SUMMARY Negative-pressure wound therapy with instillation and dwell (NPWTi-d) is an option for management of wounds with exposed orthopedic fixation hardware. The mechanical effect of the negative-pressure therapy works to contract the wound edges, and the instillation of solution and its subsequent removal help remove infectious material. NPWTi-d also promotes robust granulation tissue formation. In this article, we discuss the science behind NPWTi-d and its role in the treatment of wounds with indwelling orthopedic fixation hardware.

Abstract
Wound infection involving hardware can be notoriously difficult to treat, often requiring the removal of the infected implant. The goal of this study was to determine the utility of instillation negative pressure wound therapy to help eradicate infection and allow for definitive wound closure in patients without removing the infected hardware. A retrospective review was performed on the outcomes of 28 patients who presented with open wounds with exposed or infected hardware and who were treated with a combination of surgical debridement and negative pressure wound therapy with instillation (NPWTi). Eleven patients were treated for infected spinal hardware, 12 for extremity, and 5 for sternal hardware. Twenty-five of 28 (89%) patients had successful retention or replacement of hardware, with clearance of infection and healed wounds. Original hardware was maintained in 17 of 28 (61%) patients. In 11 patients, original hardware was removed, with subsequent replacement in eight of those patients after a clean wound was achieved. Average time to definitive closure was 12.6 days. Average follow-up was 135 days. This series supports NPWTi as an effective adjunct therapy to help expeditiously eradicate hardware infection, allowing for hardware retention.

Abstract
Objective: To determine the utility of instillation negative pressure wound therapy (NPWT) in achieving eradication of infection and definitive wound closure in patients with infected left ventricular assist device (LVAD). Approach: A retrospective review was performed in a series of patients with infected and exposed LVADs who were treated with instillation NPWT in conjunction with surgical debridement. Results: Three consecutive patients were included who developed periprosthetic infection subsequent to LVAD implantation. In all cases, the utilization of a vacuum-assisted closure with instillation (VACi) along with surgical debridement and IV antibiotics eradicated infection resulting in successful retention of hardware. Cases 1 and 2 received definitive wound closure within 3 and 12 days of starting treatment, respectively. Case 3 initially deferred surgery in favor of local wound care. Eventually the patient elected for surgical treatment and underwent closure 164 days after initial presentation. All three patients healed completely without residual evidence of infection. Flap reconstruction with a pedicled rectus flap was used to achieve definitive closure in all patients. One patient subsequently required pump replacement secondary to thrombosis and mechanical pump failure. Innovation: LVAD infections are met with high morbidity and mortality rates, and timely salvage is critical. In this initial series, VACi has proven a viable therapy option to help control and eradicate infection without LVAD removal. Conclusion: This series illustrates the value of newer techniques such as VACi in combination with surgical debridement and antibiotic therapy in effectively salvaging LVADs that were infected.

Abstract
Diabetic foot ulcers are one of the most common complications of diabetes with high morbidity and mortality. Negative pressure wound therapy (NPWT) is one of the treatment modalities that facilitates the wound healing process; however, its molecular mechanism remains unclear. The aim of this study was to investigate the mechanism of action of NPWT in the treatment of diabetic foot ulcers via measuring the tissue expression of genes related to the wound healing process. The study included 40 patients with diabetic foot ulceration, 20 of them received NPWT and the other 20 were a control group treated with advanced moist therapy. Granulation tissue biopsies were obtained before and 10 days after treatment in both groups and subjected to real-time polymerase chain reaction to measure the mRNA expression of TGF-β1, VEGF, TNF-α, IL-1β, MMP-1, MMP-9 and TIMP-1 which are involved in the wound healing pathway. After 10 days of treatment with NPWT, the mRNA levels of IL-1β, TNF-α, MMP-1, and MMP-9 were significantly downregulated, while the levels of VEGF, TGF-β1 and TIMP-1 were significantly increased. Our study demonstrated that NPWT promotes wound healing in diabetic foot ulcers possibly by affecting growth factors, inflammatory cytokines, and matrix metalloproteinases.

Abstract
Objectives The aim of this study was to perform an updated systematic review and meta-analysis to assess the clinical efficacy, safety, and cost-effectiveness of negative-pressure wound therapy (NPWT) in the treatment of diabetic foot ulcers (DFUs). Methods We searched the Cochrane Library, MEDLINE, EMBASE, Ovid, and Chinese Biological Medicine databases up to June 30, 2016. We also manually searched the articles from reference lists of the retrieved articles, which used the NPWT system in studies of vacuum-assisted closure therapy. Studies were identified and selected, and two independent reviewers extracted data from the studies. Results A total of eleven randomized controlled trials, which included a total of 1,044 patients, were selected from 691 identified studies. Compared with standard dressing changes, NPWT had a higher rate of complete healing of ulcers (relative risk, 1.48; 95% confidence interval [CI]: 1.24–1.76; P<0.001), shorter healing time (mean difference, −8.07; 95% CI: −13.70– −2.45; P=0.005), greater reduction in ulcer area (mean difference, 12.18; 95% CI: 8.50–15.86; P<0.00001), greater reduction in ulcer depth (mean difference, 40.82; 95% CI: 35.97–45.67; P<0.00001), fewer amputations (relative risk, 0.31; 95% CI: 0.15–0.62; P=0.001), and no effect on the incidence of treatment-related adverse effects (relative risk, 1.12; 95% CI: 0.66–1.89; P=0.68). Meanwhile, many analyses showed that the NPWT was more cost-effective than standard dressing changes. Conclusion These results indicate that NPWT is efficacious, safe, and cost-effective in treating DFUs.
