Meta-Analysis Review
Despite the fact that machine learning (ML) algorithms to construct predictive models for pressure injury development are widely reported, the performance of the model remains unknown. The goal of the review was to systematically appraise the performance of ML models in predicting pressure injury. PubMed, Embase, Cochrane Library, Web of Science, CINAHL, Grey literature and other databases were systematically searched. Original journal papers were included which met the inclusion criteria. The methodological quality was assessed independently by two reviewers using the Prediction Model Risk of Bias Assessment Tool (PROBAST). Meta-analysis was performed with Metadisc software, with the area under the receiver operating characteristic curve, sensitivity and specificity as effect measures. Chi-squared and I tests were used to assess the heterogeneity. A total of 18 studies were included for the narrative review, and 14 of them were eligible for meta-analysis. The models achieved excellent pooled AUC of 0.94, sensitivity of 0.79 (95% CI [0.78-0.80]) and specificity of 0.87 (95% CI [0.88-0.87]). Meta-regressions did not provide evidence that model performance varied by data or model types. The present findings indicate that ML models show an outstanding performance in predicting pressure injury. However, good-quality studies should be conducted to verify our results and confirm the clinical value of ML in pressure injury development.

Meta-Analysis Review
BACKGROUND
Venous leg ulcers (VLUs) are a serious manifestation of chronic venous disease affecting up to 3% of the adult population. This typically recalcitrant and recurring condition significantly impairs quality of life, and its treatment places a heavy financial burden upon healthcare systems. The longstanding mainstay treatment for VLUs is compression therapy. Surgical removal of incompetent veins reduces the risk of ulcer recurrence. However, open surgery is an unpopular option amongst people with VLU, and many people are unsuitable for it. The efficacy of the newer, minimally-invasive endovenous techniques has been established in uncomplicated superficial venous disease, and these techniques can also be used in the management of VLU. When used with compression, endovenous ablation aims to further reduce pressure in the veins of the leg, which may impact ulcer healing.
OBJECTIVES
To determine the effects of superficial endovenous ablation on the healing and recurrence of venous leg ulcers and the quality of life of people with venous ulcer disease.
SEARCH METHODS
In April 2022 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scrutinised reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions on the language of publication, but there was a restriction on publication year from 1998 to April 2022 as superficial endovenous ablation is a comparatively new technology.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing endovenous ablative techniques with compression versus compression therapy alone for the treatment of VLU were eligible for inclusion. Studies needed to have assessed at least one of the following primary review outcomes related to objective measures of ulcer healing such as: proportion of ulcers healed at a given time point; time to complete healing; change in ulcer size; proportion of ulcers recurring over a given time period or at a specific point; or ulcer-free days. Secondary outcomes of interest were patient-reported quality of life, economic data and adverse events.
DATA COLLECTION AND ANALYSIS
Two reviewers independently assessed studies for eligibility, extracted data, carried out risk of bias assessment using the Cochrane RoB 1 tool, and assessed GRADE certainty of evidence.
MAIN RESULTS
The previous version of this review found no RCTs meeting the inclusion criteria. In this update, we identified two eligible RCTs and included them in a meta-analysis. There was a total of 506 participants with an active VLU, with mean durations of 3.1 months ± 1.1 months in the EVRA trial and 60.5 months ± 96.4 months in the VUERT trial. Both trials randomised participants to endovenous treatment and compression or compression alone, however the compression alone group in the EVRA trial received deferred endovenous treatment (after ulcer healing or from six months). There is high-certainty evidence that combined endovenous ablation and compression compared with compression therapy alone, or compression with deferred endovenous treatment, improves time to complete ulcer healing (pooled hazard ratio (HR) 1.41, 95% CI 1.36 to 1.47; I = 0%; 2 studies, 466 participants). There is moderate-certainty evidence that the proportion of ulcers healed at 90 days is probably higher with combined endovenous ablation and compression compared with compression therapy alone or compression with deferred endovenous treatment (risk ratio (RR) 1.14, 95% CI 1.00 to 1.30; I = 0%; 2 studies, 466 participants). There is low-certainty evidence showing an unclear effect on ulcer recurrence at one year in people with healed ulcers with combined endovenous treatment and compression when compared with compression alone or compression with deferred endovenous treatment (RR 0.29, 95% CI 0.03 to 2.48; I = 78%; 2 studies, 460 participants). There is also low-certainty evidence that the median number of ulcer-free days at one year may not differ (306 (interquartile range (IQR) 240 to 328) days versus 278 (IQR 175 to 324) days) following combined endovenous treatment and compression when compared with compression and deferred endovenous treatment; (1 study, 450 participants). There is low-certainty evidence of an unclear effect in rates of thromboembolism between groups (RR 2.02, 95% CI 0.51 to 7.97; I = 78%, 2 studies, 506 participants). The addition of endovenous ablation to compression is probably cost-effective at one year (99% probability at GBP 20,000/QALY; 1 study; moderate-certainty evidence).
AUTHORS' CONCLUSIONS
Endovenous ablation of superficial venous incompetence in combination with compression improves leg ulcer healing when compared with compression alone. This conclusion is based on high-certainty evidence. There is moderate-certainty evidence to suggest that it is probably cost-effective at one year and low certainty evidence of unclear effects on recurrence and complications. Further research is needed to explore the additional benefit of endovenous ablation in ulcers of greater than six months duration and the optimal modality of endovenous ablation.

Meta-Analysis Review
AIM
Pressure injuries are a significant health care problem worldwide, and many factors influence their occurrence and development. The purpose of this systematic review and meta-analysis was to investigate the role of nutritional status in the development rate of pressure injuries as a potentially modifiable risk factor.
METHODS
Study designs included cohort (prospective and retrospective), case-control, and RCTs if the association between nutrition status and pressure injuries was reported. Databases searched included: PubMed, CINAHL, Embase, Scopus, Web of Science, and Cochrane Library on April 20th, 2022. The data were analyzed using OR and random effect model in Revman5.3 and STATA 15 Software. Report this systematic review and meta-analysis according to the PRISMA 2020 statement.
RESULTS
A total of 22 separate studies were retained in this systematic review. Of these, 16 articles were included in the meta-analysis. Three studies were assessed as low risk and sixteen as a moderate risk of bias. All RCTs were B quality. The odds ratio of the incidence of pressure injuries in malnourished and non-malnourished patients was 3.66(95% CI: 2.77-4.83). In the three RCTs studies(n = 870), the odds ratio of the incidence of pressure ulcers in patients with standard nutrition to those with specific nutritional interventions was 1.35(95%CI:1.02-1.78).
CONCLUSIONS
This systematic review and meta-analysis showed that nutritional status is significantly associated with pressure injuries. Malnutrition can increase the incidence of pressure injuries, and specific nutritional interventions can reduce the incidence of pressure injuries compared to standard nutrition.

Review
BACKGROUND
The high burden of pressure ulcers (PUs) in Sub-Saharan Africa (SSA), coupled with the limited resources, underscores the need for preventive and context-specific treatment strategies.
PURPOSE
Therefore, the purpose of this systematic review was to establish and elucidate PU prevention and treatment interventions tested in SSA.
METHODS
This systematic review of the literature used, PRISMA to guide the search.
FINDINGS
The review identified nine studies on PU prevention (three) and treatment (six). Low-cost interventions assembled from locally available materials and multifaceted policies significantly prevented and treated PUs. The interventions included wound dressing agents, simple negative pressure suction devices that significantly treated PUs, and water-based bed surfaces.
DISCUSSION
There were gaps in the interventions that have been proven successful in other global settings.
CONCLUSION
In SSA, there is a need for nurses to tailor, test, and disseminate findings from evidence-based projects for PU prevention that have been successful in similar settings.

Review
OBJECTIVE
to map the instruments for risk assessment of pressure ulcers in adults in critical situation in intensive care units; identify performance indicators of the instrument, and the appreciation of users regarding the instruments' use/limitations.
METHOD
a scoping review. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews in the writing of the study. We carried out the searches in the EBSCOhost search tool for 8 databases, resulting in 1846 studies, of which 22 studies compose the sample.
RESULTS
we identified two big instrument groups: generalist [Braden, Braden (ALB), Emina, Norton-MI, RAPS, and Waterlow]; and specific (CALCULATE, Cubbin & Jackson, EVARUCI, RAPS-ICU, Song & Choi, Suriaidi and Sanada, and COMHON index). Regarding the predictive value, EVARUCI and CALCULATE presented better results for performance indicators. Concerning appreciation/limitations indicated by users, we highlight the CALCULATE scale, followed by EVARUCI and RAPS-ICU, although they still need future adjustments.
CONCLUSION
the mapping of the literature showed that the evidence is sufficient to indicate one or more instruments for the risk assessment of pressure ulcers for adults in critical situation in intensive care units. (1) The risk assessment instrument must be applied to the patient's specificities. (2) The instruments are divided into two groups: generalist and specific. (3) The EVARUCI and CALCULATE instruments presented better results. (4) The EVARACI presented better results in terms of performance indicators. (5) The CALCULATE highlights itself for being recent scale, appropriate, simple, and easy to use.

Meta-Analysis
AIM
To investigate the effectiveness of different dressings on pressure injuries and screen the dressings for efficacy.
DESIGN
Systematic review and network meta-analysis.
METHODS
Articles published from several electronic databases and other resources were selected. Two reviewers independently selected studies, extracted data and assessed the quality of selected studies.
RESULTS
Twenty-five studies that contained data on moist dressings (hydrocolloidal dressing, foam dressing, silver ion dressing, biological wound dressing, hydrogel dressing, polymeric membrane dressing) and sterile gauze dressings (traditional gauze dressings) were included. All RCTs were at a medium to high risk of bias. Moist dressings were found to be more advantageous than the traditional dressings. Hydrocolloid dressings [RR = 1.38, 95% CI (1.18, 1.60)] showed a higher cure rate than sterile gauze dressing and foam dressings [RR = 1.37, 95% CI (1.16, 1.61)]. Silver ion dressings [RR = l.37, 95% CI (1.08, 1. 73)] showed a higher cure rate than sterile gauze dressings. Sterile gauze dressing dressings [RR = 0.51, 95% CI (0.44, 0.78)] showed a lower cure rate compared with polymeric membrane dressings; whereas Sterile gauze dressing dressings [RR = 0.80, 95% CI (0.47, 1.37)] had a lower cure rate compared to biological wound dressings. Foam and hydrocolloid dressings were associated with the least healing time. Few dressing changes were required for moist dressings.

Advances in Skin & Wound Care Sep 2023To review the literature about combined urologic and reconstructive management of pressure injuries (PIs) with urethral fistulas.
OBJECTIVE
To review the literature about combined urologic and reconstructive management of pressure injuries (PIs) with urethral fistulas.
DATA SOURCES
Authors searched the PubMed, MEDLINE, EMBASE, and Cochrane databases using the following keywords: "Perineum" or "Perineal" and "Pressure Ulcers" or '' Pressure Injury'' and "Urethral Fistula."
STUDY SELECTION
The search yielded a total of 95 articles. Study selection followed the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement, and the study was designed according to the PICOS (Population, Intervention, Comparison, Outcomes, Study) guidelines. Congress abstracts, letters to the editor, and editorial comments were excluded. After screening, a total of 9 studies (30 patients) were included in the review.
DATA EXTRACTION
Included patients received treatment for a perineal or ischial PI associated with a urinary fistula. The outcomes were recovery, complications, treatment failure, recurrence, and illness-related death.
DATA SYNTHESIS
Pressure injuries were mainly ischiatic (50%) and perineal (43%). Forty-six percent of patients had spinal cord injuries, and at least 40% reported voiding dysfunction. Sixteen percent had previous ischiectomy. Flaps such as posterior thigh flap, biceps femoris flap, and inferiorly based transverse rectus abdominal muscle flap had 88% to 100% success rates when used with urinary diversion techniques. Suprapubic cystostomy, the simplest method of urinary diversion, was successful in 47% of cases when performed alone and in 100% when combined with a pedicled omental flap or a transverse rectus abdominal muscle flap.
CONCLUSIONS
Prevention and wound care are essential for PI management, but when combined with a urinary fistula, surgical management is unavoidable. Urinary diversion is essential before undergoing any type of ulcer reconstruction. Urethral reconstruction showed favorable results, further strengthened when combined with a musculocutaneous flap.

Review
The aim of this review study is to investigate the nurses' knowledge and related factors towards the prevention of medical device-related pressure ulcers (MDRPUs). An extensive search was conducted in international electronic databases such as PubMed, Web of Science, and Scopus, and Persian databases, such as Iranmedex and the Scientific Information Database from December 1, 2022. During this search, keywords extracted from Medical Subject Headings, such as "Prevention knowledge," "Nurse," "Pressure ulcer," "Equipment and Supplies," and "Intensive Care Units" were used. The quality of the present studies in this review was evaluated based on the appraisal tool for cross-sectional studies (AXIS tool). A total of 1847 nurses participated in this review from five studies, and the majority of them (82.94%) were female. The mean age of the participants was 31.40 (SD = 5.97). The mean score of MDRPUs prevention knowledge in nurses based on PU2014 scale and researcher-made questionnaires were 16.50 (SD = 3.74) out of 31 and 65.49 (SD = 6.33) out of 100, respectively. The knowledge of nurses is influenced by factors such as age, sex, level of education, work experience, technical titles, type of hospital, level of hospital, and type of ward. Various factors had a significant positive relationship with nurses' MDRPUs prevention knowledge, which includes level of education, work experience, previous training on MDRPU, having a wound care certificate, an online search about MDRPU, and attitude and practise towards MDRPU prevention. At the same time, nurses' knowledge about the prevention of MDRPUs had a significant negative relationship with the time interval since last participating in MDRPU training or workshop. Overall, the level of MDRPUs prevention knowledge among nurses was insufficient to moderate. Therefore, it is suggested to provide facilities for nurses to receive the necessary training.

Review
BACKGROUND
Hyaluronic acid is synthesised in plasma membranes and can be found in extracellular tissues. It has been suggested that the application of hyaluronic acid to chronic wounds may promote healing, and the mechanism may be due to its ability to maintain a moist wound environment which helps cell migration in the wound bed.
OBJECTIVES
To evaluate the effects of hyaluronic acid (and its derivatives) on the healing of chronic wounds.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was February 2022.
SELECTION CRITERIA
We included randomised controlled trials that compared the effects of hyaluronic acid (as a dressing or topical agent) with other dressings on the healing of pressure, venous, arterial, or mixed-aetiology ulcers and foot ulcers in people with diabetes.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane. We assessed the certainty of the evidence using the GRADE approach.
MAIN RESULTS
We included 12 trials (13 articles) in a qualitative synthesis, and were able to combine data from four trials in a quantitative analysis. Overall, the included trials involved 1108 participants (mean age 69.60 years) presenting 178 pressure ulcers, 54 diabetic foot ulcers, and 896 leg ulcers. Sex was reported for 1022 participants (57.24% female). Pressure ulcers It is uncertain whether there is a difference in complete healing (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.58 to 2.35); change in ulcer size (mean difference (MD) 25.60, 95% CI 6.18 to 45.02); or adverse events (none reported) between platelet-rich growth factor (PRGF) + hyaluronic acid and PRGF because the certainty of evidence is very low (1 trial, 65 participants). It is also uncertain whether there is a difference in complete healing between lysine hyaluronate and sodium hyaluronate because the certainty of evidence is very low (RR 2.50, 95% CI 0.71 to 8.83; 1 trial, 14 ulcers from 10 participants). Foot ulcers in people with diabetes It is uncertain whether there is a difference in time to complete healing between hyaluronic acid and lyophilised collagen because the certainty of evidence is very low (MD 16.60, 95% CI 7.95 to 25.25; 1 study, 20 participants). It is uncertain whether there is a difference in complete ulcer healing (RR 2.20, 95% CI 0.97 to 4.97; 1 study, 34 participants) or change in ulcer size (MD -0.80, 95% CI -3.58 to 1.98; 1 study, 25 participants) between hyaluronic acid and conventional dressings because the certainty of evidence is very low. Leg ulcers We are uncertain whether there is a difference in complete wound healing (RR 0.98, 95% CI 0.26 to 3.76), percentage of adverse events (RR 0.79, 95% CI 0.22 to 2.80), pain (MD 2.10, 95% CI -5.81 to 10.01), or change in ulcer size (RR 2.11, 95% CI 0.92 to 4.82) between hyaluronic acid + hydrocolloid and hydrocolloid because the certainty of evidence is very low (1 study, 125 participants). It is uncertain whether there is a difference in change in ulcer size between hyaluronic acid and hydrocolloid because the certainty of evidence is very low (RR 1.02, 95% CI 0.84 to 1.25; 1 study, 143 participants). We are uncertain whether there is a difference in complete wound healing between hyaluronic acid and paraffin gauze because the certainty of evidence is very low (RR 2.00, 95% CI 0.21 to 19.23; 1 study, 24 ulcers from 17 participants). When compared with neutral vehicle, hyaluronic acid probably improves complete ulcer healing (RR 2.11, 95% CI 1.46 to 3.07; 4 studies, 526 participants; moderate-certainty evidence); may slightly increase the reduction in pain from baseline (MD -8.55, 95% CI -14.77 to -2.34; 3 studies, 337 participants); and may slightly increase change in ulcer size, measured as mean reduction from baseline to 45 days (MD 30.44%, 95% CI 15.57 to 45.31; 2 studies, 190 participants). It is uncertain if hyaluronic acid alters incidence of infection when compared with neutral vehicle (RR 0.89, 95% CI 0.53 to 1.49; 3 studies, 425 participants). We are uncertain whether there is a difference in change in ulcer size (cm) between hyaluronic acid and dextranomer because the certainty of evidence is very low (MD 5.80, 95% CI -10.0 to 21.60; 1 study, 50 participants). We downgraded the certainty of evidence due to risk of bias or imprecision, or both, for all of the above comparisons. No trial reported health-related quality of life or wound recurrence. Measurement of change in ulcer size was not homogeneous among studies, and missing data precluded further analysis for some comparisons.
AUTHORS' CONCLUSIONS
There is currently insufficient evidence to determine the effectiveness of hyaluronic acid dressings in the healing of pressure ulcers or foot ulcers in people with diabetes. We found evidence that hyaluronic acid probably improves complete ulcer healing and may slightly decrease pain and increase change in ulcer size when compared with neutral vehicle. Future research into the effects of hyaluronic acid in the healing of chronic wounds should consider higher sample size and blinding to minimise bias and improve the quality of evidence.
