BACKGROUND
It is critical that interventions used to enhance the healing of chronic foot ulcers in diabetes are backed by high-quality evidence and cost-effectiveness. In previous years, the systematic review accompanying guidelines published by the International Working Group of the Diabetic Foot performed 4-yearly updates of previous searches, including trials of prospective, cross-sectional and case-control design.
AIMS
Due to a need to re-evaluate older studies against newer standards of reporting and assessment of risk of bias, we performed a whole new search from conception, but limiting studies to randomised control trials only.
MATERIALS AND METHODS
For this systematic review, we searched PubMed, Scopus and Web of Science databases for published studies on randomised control trials of interventions to enhance healing of diabetes-related foot ulcers. We only included trials comparing interventions to standard of care. Two independent reviewers selected articles for inclusion and assessed relevant outcomes as well as methodological quality.
RESULTS
The literature search identified 22,250 articles, of which 262 were selected for full text review across 10 categories of interventions. Overall, the certainty of evidence for a majority of wound healing interventions was low or very low, with moderate evidence existing for two interventions (sucrose-octasulfate and leucocyte, platelet and fibrin patch) and low quality evidence for a further four (hyperbaric oxygen, topical oxygen, placental derived products and negative pressure wound therapy). The majority of interventions had insufficient evidence.
CONCLUSION
Overall, the evidence to support any other intervention to enhance wound healing is lacking and further high-quality randomised control trials are encouraged.

Many clinical management strategies have been proposed to deal with diabetic foot ulcers. However, the occurrence and recurrence of foot ulcers remain the major problems for diabetics. This study aims to identify, visualize, and characterize the meta-analyses on diabetic foot ulcer research. Articles published online were retrieved from the Web of Science core collection database using a search query incorporating MeSH terms and topics related to diabetic foot ulcers and meta-analysis. The publications were then analyzed for basic characteristics, including publication year, countries, topics covered, references, and keywords discussed in the articles. Data visualization was performed using CiteSpace. 334 meta-analyses and systematic reviews on diabetic foot ulcers were identified. The number of publications has experienced rapid growth in recent years (nearly 6-fold since 2016). The United States, China, Netherlands, England, and Australia had a strong collaboration in the contribution of publication. 7 primary topics were summarized from the top 100 highly cited publications: #1 Interventions (proportion: 59%), #2 Risk factors and Prevention (22%), #3 Epidemiology analysis (6%), #4 Cost-effectiveness of interventions (5%), #5 Long-term prognosis (3%), #6 Quality of life analysis (3%), and #7 Economic burden analysis (2%). Footwear and offloading interventions, multidisciplinary care, hyperbaric oxygen, platelet-rich plasma, and negative pressure wound therapies are highly regarded in terms of intervention. Diabetic foot osteomyelitis, peripheral diabetic neuropathy, chronic limb-threatening ischemia, and infections are the main comorbidities. In recent years, offloading interventions, debridement, telemedicine, long-term prognosis, and economic burden analyses have gradually received attention. Individualized treatment, multidisciplinary collaboration, quality of life considerations, and economic burden analyses are the long-term concerns.

Meta-Analysis Review
This review aims to systematically evaluate the association between hypertension and pressure ulcer (PU). PubMed, Embase, Web of Science, and Cochrane Library were searched for studies from their inception until September 12, 2023. Literature search, data extraction, and quality assessment were conducted independently by two researchers. The random-effects model was used to calculate the combined odds ratio (OR) and corresponding 95% confidence interval (CI) of hypertension in patients with PU; subgroup analyses were performed to explore the source of between-study heterogeneity; sensitivity analysis was used to test the robust of the combined result; and funnel plot and Egger's test were used to assess the publication bias. Finally, a total of 19 studies with 564 716 subjects were included; the overall pooled result showed no significant association between hypertension and risk of developing PU (OR = 1.15, 95% CI = 0.90-1.47, p = 0.27); and the sensitivity analysis and publication bias analysis showed robust of the combined result. Subgroup analysis indicated a significant association between hypertension and PU when the primary disease was COVID-19 (OR = 1.73, 95% CI = 1.35-2.22, p < 0.0001). No association between hypertension and PU was seen in subgroup analysis on the patient source and study design. In sum, there is no significantly statistical association between hypertension and the occurrence of PU in most cases, while the risk of PU significantly elevates among COVID-19 patients combined with hypertension regardless of patient source and study design.

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.

BACKGROUND
Up to 1% of adults will have a leg ulcer at some time. Most leg ulcers are venous in origin and are caused by high pressure in the veins due to blockage or damaged valves. Venous ulcer prevention and treatment typically involves the application of compression bandages/stockings to improve venous return and thus reduce pressure in the legs. Other treatment options involve removing or repairing veins. Most venous ulcers heal with compression therapy, but ulcer recurrence is common. For this reason, clinical guidelines recommend that people continue with compression treatment after their ulcer has healed. This is an update of a Cochrane review first published in 2000 and last updated in 2014.
OBJECTIVES
To assess the effects of compression (socks, stockings, tights, bandages) for preventing recurrence of venous leg ulcers.
SEARCH METHODS
In August 2023, we searched the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, Embase, three other databases, and two ongoing trials registries. We also scanned the reference lists of included studies and relevant reviews and health technology reports. There were no restrictions on language, date of publication, or study setting.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that evaluated compression bandages or hosiery for preventing the recurrence of venous ulcers.
DATA COLLECTION AND ANALYSIS
At least two review authors independently selected studies, assessed risk of bias, and extracted data. Our primary outcome was reulceration (ulcer recurrence anywhere on the treated leg). Our secondary outcomes included duration of reulceration episodes, proportion of follow-up without ulcers, ulceration on the contralateral leg, noncompliance with compression therapy, comfort, and adverse effects. We assessed the certainty of evidence using GRADE methodology.
MAIN RESULTS
We included eight studies (1995 participants), which were published between 1995 and 2019. The median study sample size was 249 participants. The studies evaluated different classes of compression (UK class 2 or 3 and European (EU) class 1, 2, or 3). Duration of follow-up ranged from six months to 10 years. We downgraded the certainty of the evidence for risk of bias (lack of blinding), imprecision, and indirectness. EU class 3 compression stockings may reduce reulceration compared with no compression over six months (risk ratio (RR) 0.46, 95% confidence interval (CI) 0.27 to 0.76; 1 study, 153 participants; low-certainty evidence). EU class 1 compression stockings compared with EU class 2 compression stockings may have little or no effect on reulceration over 12 months (RR 1.70, 95% CI 0.67 to 4.32; 1 study, 99 participants; low-certainty evidence). There may be little or no difference in rates of noncompliance over 12 months between people using EU class 1 stockings and people using EU class 2 stockings (RR 1.22, 95% CI 0.40 to 3.75; 1 study, 99 participants; low-certainty evidence). UK class 2 hosiery compared with UK class 3 hosiery may be associated with a higher risk of reulceration over 18 months to 10 years (RR 1.55, 95% CI 1.26 to 1.91; 5 studies, 1314 participants; low-certainty evidence). People who use UK class 2 hosiery may be more compliant with compression treatment than people who use UK class 3 hosiery over 18 months to 10 years (RR for noncompliance 0.69, 95% CI 0.49 to 0.99; 5 studies, 1372 participants; low-certainty evidence). There may be little or no difference between Scholl UK class 2 compression stockings and Medi UK class 2 compression stockings in terms of reulceration (RR 0.77, 95% CI 0.47 to 1.28; 1 study, 166 participants; low-certainty evidence) and noncompliance (RR 0.97, 95% CI 0.84.1 to 12; 1 study, 166 participants; low-certainty evidence) over 18 months. No studies compared different lengths of compression (e.g. below-knee versus above-knee), and no studies measured duration of reulceration episodes, ulceration on the contralateral leg, proportion of follow-up without ulcers, comfort, or adverse effects.
AUTHORS' CONCLUSIONS
Compression with EU class 3 compression stockings may reduce reulceration compared with no compression over six months. Use of EU class 1 compression stockings compared with EU class 2 compression stockings may result in little or no difference in reulceration and noncompliance over 12 months. UK class 3 compression hosiery may reduce reulceration compared with UK class 2 compression hosiery; however, higher compression may lead to lower compliance. There may be little to no difference between Scholl and Medi UK class 2 compression stockings in terms of reulceration and noncompliance. There was no information on duration of reulceration episodes, ulceration on the contralateral leg, proportion of follow-up without ulcers, comfort, or adverse effects. More research is needed to investigate acceptable modes of long-term compression therapy for people at risk of recurrent venous ulceration. Future trials should consider interventions to improve compliance with compression treatment, as higher compression may result in lower rates of reulceration.

Review
INTRODUCTION
Pressure Ulcers (PUs) are a major healthcare issue leading to prolonged hospital stays and decreased quality of life. Monitoring body position changes using sensors could reduce workload, improve turn compliance and decrease PU incidence.
METHOD
This systematic review assessed the clinical applicability of different sensor types capable of in-bed body position detection.
RESULTS
We included 39 articles. Inertial sensors were most commonly used (n = 14). This sensor type has high accuracy and is equipped with a 2-4 hour turn-interval warning system increasing turn compliance. The second-largest group were piezoresistive (pressure) sensors (n = 12), followed by load sensors (n = 4), piezoelectric sensors (n = 3), radio wave-based sensors (n = 3) and capacitive sensors (n = 3). All sensor types except inertial sensors showed a large variety in the type and number of detected body positions. However, clinically relevant position changes such as trunk rotation and head of bed elevation were not detected or tested.
CONCLUSION
Inertial sensors are the benchmark sensor type regarding accuracy and clinical applicability but these sensors have direct patient contact and (re)applying the sensors requires the effort of a nurse. Other sensor types without these disadvantages should be further investigated and developed. We propose the Pressure Ulcer Position System (PUPS) guideline to facilitate this.

Review
Venous leg ulcer (VLU) is the most severe manifestations of chronic venous disease, which has characterized by slow healing and high recurrence rates. This typically recalcitrant and recurring condition significantly impairs quality of life, prevention of VLU recurrence is essential for helping to reduce the huge burden of patients and health resources, the purpose of this scoping review is to analyse and determine the intervention measures for preventing recurrence of the current reported, to better inform healthcare professionals and patients. The PubMed, Embase, Web of Science, Cochrane Library databases, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wan Fang Data and Chongqing VIP Information (CQVIP) were accessed up to June 17, 2023. This scoping review followed the five-steps framework described by Arksey and O'Malley and the PRISMA extension was used to report the review. Eleven articles were included with a total of 1503 patients, and adopted the four effective measures: compression therapy, physical activity, health education, and self-care. To conclude, the use of high pressure compression treatment for life, supplementary exercise therapy, and strengthen health education to promote self-care are recommended strategies of VLU prevention and recurrence. In addition, the importance of multi-disciplinary teams to participate in the care of VLU in crucial.

BACKGROUND
The development of ulcers in the plantar region of the diabetic foot originates mainly from sites subjected to high pressure. The monitoring of these events using maximum allowable pressure thresholds is a fundamental procedure in the prevention of ulceration and its recurrence.
OBJECTIVE
The aim of this review was to identify data in the literature that reveal an objective threshold of plantar pressure in the diabetic foot, where pressure is classified as promoting ulceration. The aim is not to determine the best and only pressure threshold for ulceration, but rather to clarify the threshold values most used in clinical practice and research, also considering the devices used and possible applications for offloading plantar pressure.
DESIGN
A systematic review.
METHODS
The search was performed in three electronic databases, by the PRISMA methodology, for studies that used a pressure threshold to minimize the risk of ulceration in the diabetic foot. The selected studies were subjected to eligibility criteria.
RESULTS
Twenty-six studies were included in this review. Seven thresholds were identified, five of which are intended for the inside of the shoe: a threshold of average peak pressure of 200 kPa; 25 % and 40-80 % reduction from initial baseline pressure; 32-35 mm Hg for a capillary perfusion pressure; and a matrix of thresholds based on patient risk, shoe size and foot region. Two other thresholds are intended for the barefoot, 450 and 750 kPa. The threshold of 200 kPa of pressure inside the shoe is the most agreed upon among the studies. Regarding the prevention of ulceration and its recurrence, the efficacy of the proposed threshold matrix and the threshold of reducing baseline pressure by 40-80 % has not yet been evaluated, and the evidence for the remaining thresholds still needs further studies.
CONCLUSIONS
Some heterogeneity was found in the studies, especially regarding the measurement systems used, the number of regions of interest and the number of steps to be considered for the threshold. Even so, this review reveals the way forward to obtain a threshold indicative of an effective steppingstone in the prevention of diabetic foot ulcer.

Meta-Analysis Review
BACKGROUND
Pressure ulcers are localized injuries to the skin or the underlying tissue, or both, and are common in older and immobile people, people with diabetes, vascular disease, or malnutrition, as well as those who require intensive or palliative care. People with pressure ulcers often suffer from severe pain and exhibit social avoidance behaviours. The prevention and treatment of pressure ulcers involves strategies to optimize hydration, circulation, and nutrition. Adequate nutrient intake can reduce the risk factor of malnutrition and promote wound healing in existing pressure ulcers. However, it is unclear which nutrients help prevent and treat pressure ulcers. This is an update of an earlier Cochrane Review.
OBJECTIVES
To evaluate the benefits and harms of nutritional interventions (special diets, supplements) for preventing and treating pressure ulcers in people with or without existing pressure ulcers compared to standard diet or other nutritional interventions.
SEARCH METHODS
We used extensive Cochrane search methods. The latest search was in May 2022.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) in people with or without existing pressure ulcers, that compared nutritional interventions aimed at preventing or treating pressure ulcers with standard diet or other types of nutritional interventions.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcome for prevention studies was the proportion of participants who developed new (incident) pressure ulcers. For treatment studies, our primary outcomes were time to complete pressure ulcer healing, number of people with healed pressure ulcers, size and depth of pressure ulcers, and rate of pressure ulcer healing. Secondary outcomes were side effects, costs, health-related quality of life and acceptability. We used GRADE to assess certainty of evidence for each outcome.
MAIN RESULTS
We included 33 RCTs with 7920 participants. Data for meta-analysis were available from 6993 participants. Pressure ulcer prevention Eleven studies (with 12 arms) compared six types of nutritional interventions for the prevention of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may result in little to no difference in the proportion of participants developing a pressure ulcer (energy, protein and micronutrient supplements 248 per 1000, standard diet 269 per 1000; RR 0.92, 95% CI 0.71 to 1.19; 3 studies, 1634 participants; low-certainty evidence). Compared to standard diet, protein supplements may result in little to no difference in pressure ulcer incidence (protein 21 per 1000, standard diet 28 per 1000; RR 0.75, 95% CI 0.49 to 1.14; 4 studies, 4264 participants; low-certainty evidence). The evidence is very uncertain about the gastrointestinal side effects of these supplements (protein 109 per 1000, standard diet 155 per 1000; RR 0.70, 95% CI 0.06 to 7.96; 2 studies, 140 participants, very low-certainty evidence). The evidence is very uncertain about the effects of protein, arginine, zinc and antioxidants; L-carnitine, L-leucine, calcium, magnesium and vitamin D; EPA, GLA and antioxidants; disease-specific supplements on pressure ulcer incidence when compared to standard diet (1 study each; very low-certainty evidence for all comparisons). Pressure ulcer treatment Twenty-four studies (with 27 arms) compared 10 types of nutritional interventions or supplements for treatment of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may slightly increase the number of healed pressure ulcers (energy, protein and micronutrients 366 per 1000, standard diet 253 per 1000; RR 1.45, 95% CI 1.14 to 1.85; 3 studies, 577 participants, low-certainty evidence). The evidence is very uncertain about the effect of these supplements on gastrointestinal side effects. Compared to standard diet, the evidence is very uncertain about the effect of protein, arginine, zinc and antioxidant supplements on pressure ulcer healing (pressure ulcer area: mean difference (MD) 2 cm² smaller, 95% CI 4.54 smaller to 0.53 larger; 2 studies, 71 participants, very low-certainty evidence). The evidence on side effects of these supplements is very uncertain. Compared to standard diet, supplements with arginine and micronutrients may not increase the number of healed pressure ulcers, but the evidence suggests a slight reduction in pressure ulcer area (MD 15.8% lower, 95% CI 25.11 lower to 6.48 lower; 2 studies, 231 participants, low-certainty evidence). The evidence is very uncertain about changes in pressure ulcer scores, acceptability, and side effects of these supplements. Compared to placebo, collagen supplements probably improve the mean change in pressure ulcer area (MD 1.81 cm² smaller, 95% CI 3.36 smaller to 0.26 smaller; 1 study, 74 participants, moderate-certainty evidence). The evidence is very uncertain about the effect of these supplements on side effects. The evidence is very uncertain about the effects of vitamin C, different doses of arginine; EPA, GLA (special dietary fatty acids) and antioxidants; protein; a specialized amino acid mixture; ornithine alpha-ketoglutarate and zinc supplements on pressure ulcer healing (1 or 2 studies each; very low-certainty evidence).
AUTHORS' CONCLUSIONS
The benefits of nutritional interventions with various compositions for pressure ulcer prevention and treatment are uncertain. There may be little or no difference compared to standard nutrition or placebo. Nutritional supplements may not increase gastrointestinal side effects, but the evidence is very uncertain. Larger studies with similar nutrient compositions would reduce these uncertainties. No study investigated the effects of special diets (e.g. protein-enriched diet, vegetarian diet) on pressure ulcer incidence and healing.
