Continuous muscle pump activation by neuromuscular electrical stimulation of the common peroneal nerve in the treatment of patients with venous leg ulcers: A position paper.

The standard treatment for patients with confirmed Venous Leg Ulcers (VLUs) is compression therapy to improve the function of the calf muscle pump. There is a significant cohort of patients who are unable to tolerate optimal compression therapy or indeed any level of compression therapy. In addition, there is a cohort of patients who can tolerate compression whose ulcers show little or no evidence of healing. There is a need for ways to further improve calf muscle pump function and to improve venous ulcer healing in these patients. Published data were reviewed on the use of Muscle Pump Activation (MPA) using common peroneal nerve neuromuscular electrical stimulation (NMES) to improve calf muscle pump function. There is physiological evidence that MPA can improve calf muscle pump function and venous return in both control subjects and in patients with venous disease. The use of MPA has also been shown to improve venous flow volume and venous flow velocity on ultrasound scanning in patients with venous disease. MPA has been shown to improve microcirculation in the skin using Laser Doppler and laser Doppler Speckle Contrast Imaging, in both normal subjects as well as in patients with venous disease and VLU. A recent randomized controlled trial of MPA plus compression therapy compared with compression therapy alone, found significantly faster rates of healing with the use of MPA in addition to compression therapy. There are indications for the use of MPA as an adjunctive treatment to enhance calf muscle pump function in patients with VLU: who cannot tolerate compression therapy who can only tolerate suboptimal, low-level compression whose ulcer healing remains slow or stalled with optimal compression.

The muscle pump activator device: From evidence to lived experiences.

A chronic wound is one that fails to progress through a normal timely sequence of repair, or in which the repair process fails to restore anatomic and functional integrity after 3 months. The most common chronic wounds include venous, ischaemic and mixed leg ulcers, diabetic foot ulcers and pressure injuries. Chronic wounds place immense physical and psychosocial burden on patients and exact heavy costs for healthcare systems, with many patients continuing to live with chronic wounds even after all management options have been exhausted. The muscle pump activator (MPA) device can be used to bridge this therapeutic gap. By stimulating the common peroneal nerve to activate venous muscle pump of the leg and foot, the MPA device increases blood flow to the lower leg and foot to improve conditions for healing. Currently, evidence in the literature exist to show that the MPA device improves wound outcomes over standard compression therapy, decreases edema and increases wound healing rates. In this review, we also present a series of chronic wound patients treated with the MPA device in multicentre clinics to demonstrate the ability of the MPA device to improve wound outcomes, reduce pain and edema and improve patient quality of life.

Atopic Dermatitis: Clinical Aspects and Treatments.

GENERAL PURPOSE: To review issues related to atopic dermatitis, including its classification, clinical presentation, potential triggers, and treatment options. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Synthesize a differential diagnosis for atopic dermatitis (AD).2. Explain the classification of AD cases.3. Select triggers or exacerbating factors for AD.4. Explain pharmacologic and nonpharmacologic treatment options for patients with AD.

Atopic dermatitis is the most common eczematous inflammatory skin condition, presenting with lesions that typically appear as poorly demarcated erythematous and scaly papules and plaques. The lesions most commonly occur on flexural surfaces of the knees, elbows, and wrists and are associated with moderate to severe itching. This article focuses on the clinical presentation of atopic dermatitis and treatment options. Other related topics include epidemiology, pathogenesis, risk factors, triggers, and differential diagnoses.

Rosacea: Pathogenesis and Therapeutic Correlates.

Rosacea is a chronic inflammatory condition of which there is no cure. The pathogenesis of rosacea is likely multifactorial, involving genetic and environmental contributions. Current understanding suggests that pro-inflammatory pathways involving cathelicidins and inflammasome complexes are central to rosacea pathogenesis. Common rosacea triggers modulate these pathways in a complex manner, which may contribute to the varying severity and clinical presentations of rosacea. Established and emerging rosacea treatments may owe their efficacy to their ability to target different players in these pro-inflammatory pathways. Improving our molecular understanding of rosacea will guide the development of new therapies and the use of combination therapies.

Wound Bed Preparation 2024: Delphi Consensus on Foot Ulcer Management in Resource-Limited Settings.

GENERAL PURPOSE: To review a practical and scientifically sound application of the wound bed preparation model for communities without ideal resources. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Summarize issues related to wound assessment.2. Identify a class of drugs for the treatment of type II diabetes mellitus that has been shown to improve glycemia, nephroprotection, and cardiovascular outcomes.3. Synthesize strategies for wound management, including treatment in resource-limited settings.4. Specify the target time for edge advancement in chronic, healable wounds.

Chronic wound management in low-resource settings deserves special attention. Rural or underresourced settings (ie, those with limited basic needs/healthcare supplies and inconsistent availability of interprofessional team members) may not have the capacity to apply or duplicate best practices from urban or abundantly-resourced settings. The authors linked world expertise to develop a practical and scientifically sound application of the wound bed preparation model for communities without ideal resources. A group of 41 wound experts from 15 countries reached a consensus on wound bed preparation in resource-limited settings. Each statement of 10 key concepts (32 substatements) reached more than 88% consensus. The consensus statements and rationales can guide clinical practice and research for practitioners in low-resource settings. These concepts should prompt ongoing innovation to improve patient outcomes and healthcare system efficiency for all persons with foot ulcers, especially persons with diabetes.

Debridement options for the interprofessional team.

ABSTRACT: Debridement is a core component of chronic wound management. Although various debridement methods exist, each carries a unique patient risk level. This article discusses the different normal tissue components that are critical to safe debridement practice, various methods of wound debridement for nurses, and the importance of an interprofessional team and consulting a wound specialist.

COVID-19 Pivoted Virtual Skills Teaching Model: Project ECHO Ontario Skin and Wound Care Boot Camp.

OBJECTIVE: To describe a virtual, competency-based skin and wound care (SWC) skills training model. The ECHO (Extension for Community Healthcare Outcomes) Ontario SWC pivoted from an in-person boot camp to a virtual format because of the COVID-19 pandemic. METHODS: An outcome-based program evaluation was conducted. Participants first watched guided commentary and videos of experts performing in nine SWC multiskills videos, then practiced and video-recorded themselves performing those skills; these recordings were assessed by facilitators. Data were collected using pre-post surveys and rubric-based assessments. Descriptive statistics and thematic analysis were applied to data analysis. RESULTS: Fifty-five healthcare professionals participated in the virtual boot camp, measured by the submission of at least one video. A total of 216 videos were submitted and 215 assessment rubrics were completed. Twenty-nine participants completed the pre-boot camp survey (53% response rate) and 26 responded to the post-boot camp survey (47% response rate). The strengths of the boot camp included the applicability of virtual learning to clinical settings, boot camp supplies, tool kits, and teaching strategies. The analysis of survey responses indicated that average proficiency scores were greater than 80% for three videos, 50% to 70% for three of the videos, and less than 50% for three of the videos. Participants received lower scores in local wound care and hand washing points of contact. The barriers of the boot camp included technical issues, time, level of knowledge required at times, and lack of equipment and access to interprofessional teams. CONCLUSIONS: This virtual ECHO SWC model expanded access to practical skills acquisition. The professional development model presented here is generalizable to other healthcare domains.

Biomarkers in rosacea: A systematic review.

Rosacea is a chronic and psychologically ladened disease affecting 1%-3% of people worldwide. The identification and validation of biomarkers in rosacea patients has the potential to improve disease progression, support diagnosis, provide objective measures for clinical trials and aid in management. The objective of this review is to systematically identify all rosacea biomarkers, categorize them by type and identify trends to improve disease expression. Eligibility criteria for this review (PROSPERO CRD42023397510) include randomized controlled trials, case-control studies, cohort studies and other observational studies. No restrictions were placed on patient demographics (age, sex, ethnicity) or language of publication until February 2023. Quality of studies was assessed using the National Institute of Health quality assessment tool. The literature search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A total of 805 unique articles were screened based on the applied inclusion and exclusion criteria. After the articles were screened based on title/abstract and full-text, a total of 38 studies were included, reporting on a total of 119 unique biomarkers. The results of this review and current rosacea pathogenic mechanisms provide the greatest support for the innate cathelicidin and inflammasome, Th 1 and Th 17 pathways. The most commonly reported biomarkers include IL-1ß, TNF-α, IL-37, IFN-γ and MMP-9. Biomarkers identified in this study support current theories of rosacea pathogenesis and provide direction for research to further our knowledge. However, more research is needed to identify biomarkers panels that can provide diagnostic utility. This may be difficult due to the heterogeneity of the disease and potential differences between rosacea subtypes.

An 18-year-old female with a history of atopic march, hyperhidrosis, and eosinophilic esophagitis was diagnosed with erythromelalgia and gastrointestinal dysautonomia secondary to presumed autoimmune small fiber neuropathy. The patient experienced significant clinical improvements after the initiation of intravenous immunoglobulin therapy, supporting an underlying autoimmune disorder.

COVID-19 and Hospital-Acquired Pressure Injuries: A Systematic Review.

OBJECTIVE: To investigate the relationship between COVID-19-related variables and hospital-acquired pressure injury (HAPI) incidence. DATA SOURCES: The authors searched four databases: Cochrane, MEDLINE, EMBASE, and CINAHL. The literature search contained key terms such as "COVID-19," "hospital-acquired pressure injuries," "pressure ulcer," "pressure injury," "decubitus ulcer," and "hospitalization." STUDY SELECTION: The systematic search of the literature identified 489 publications that matched the inclusion criteria. Articles were included in the review if they were peer-reviewed publications that reported HAPI incidence for patients who were hospitalized and COVID-19 positive. Two reviewers performed the screen simultaneously, and 19 publications were included. DATA EXTRACTION: Two reviewers followed a standardized extraction form that included study and patient characteristics, COVID-19 status, HAPI characteristics, prone positioning, length of hospitalization, and HAPI prevention and treatment strategies. DATA SYNTHESIS: The authors carried out a narrative synthesis of the extracted data because the data obtained were too heterogeneous for meta-analysis. The primary outcome was HAPI incidence. CONCLUSIONS: This review identified that HAPI incidence was high among men who were COVID-19 positive, had longer hospital stays, experienced prone positioning, and had care teams without a skin and wound care expert. Future research should use more robust methodology and focus on quantitative modeling to iteratively improve inpatient HAPI guidelines.

Characteristics and Outcomes of Squamous Cell Carcinoma and Other Cutaneous Malignancies in Epidermolysis Bullosa: A Systematic Review.

OBJECTIVE: To identify cases and summarize outcomes of cutaneous malignancies in patients with epidermolysis bullosa (EB). DATA SOURCES: MEDLINE and EMBASE databases were searched on February 8, 2022. STUDY SELECTION: Original observational or experimental studies with cases of cutaneous malignancy in patients with inherited EB were included. DATA EXTRACTION: Data were extracted by two reviewers in duplicate. DATA SYNTHESIS: A total of 87 articles with 367 patients were included in this systematic review. Squamous cell carcinomas were the most common malignancy (94.3%) with a median survival of 60 months. The presence of metastasis was investigated at diagnosis in 77 patients; 18.8% of patients had detectable metastasis. Patients with squamous cell carcinoma with metastasis at diagnosis had significantly shorter median survival (16.8 months) than those without (72 months; P = .027). The remission rate was 47.6%. At the end of follow-up, 15.1% were alive with disease, and 41.6% were deceased. Other malignancies included malignant melanoma and basal cell carcinoma. The most common initial modes of management were excisions (71.9%) and amputations (17.6%). Other modes included chemotherapy (4.6%), radiation (3.9%), and no treatment (2.6%). The overall rate of recurrence or new lesions was 38.8%, with a median time of 16 months to recurrence or new lesions. Immediate recurrence was lowest following amputation (4.3%). There were no statistically significant differences in median survival among initial excision, amputation, and all other modes combined ( P = .30). CONCLUSIONS: Squamous cell carcinomas in patients with EB have a high likelihood of metastasis and mortality. Surgical excision is the most common intervention. There are no significant differences in survival among different initial management options. There is a need for research that documents and monitors outcomes of the treatment options.

Debridement: Technical Considerations and Treatment Options for the Interprofessional Team.

GENERAL PURPOSE: To enhance the learner's chronic wound debridement competence as an interprofessional team member. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Differentiate healable, maintenance, and nonhealable wounds to create a holistic debridement treatment plan using the Wound Bed Preparation paradigm.2. Evaluate active debridement options including the potential need for an interprofessional referral or specialized investigations.3. Assess chronic wound debridement options.4. Analyze case studies for appropriate clinical application of debridement modalities.

Debridement is a critical component in the management of both acute and chronic wounds. Six reviewed methods of debridement exist, and specific techniques are more appropriate to match patient needs with available clinical resources. Accurate differentiation between healable, maintenance, and nonhealable wounds is paramount when determining whether a wound would benefit from debridement. Clinical assessment includes review of the patient's underlying medical conditions/ previous surgeries along with the history and progression of the wound. Awareness of the physiologic wound bed preparation components that contribute to the current wound status will direct treatment of the abnormal components. Optimal wound status includes complete healing or reduced abnormal wound-related symptoms or signs. Debridement competency requires an awareness of the six types of debridement, their clinical utility, and appropriate patient selection. Providers need to assess patients' wounds, triage them, and refer them as necessary to an interprofessional setting. For stalled but healable wounds, specialized testing may be necessary when managing patients who would benefit from more invasive or advanced forms of wound care. This article informs providers on the training and experience required for specific debridement techniques depending on the wound etiology.

Results of the 2022 Wound Survey on Skin Failure/End-of-Life Terminology and Pressure Injuries.

OBJECTIVE: To summarize the major findings of a survey first conducted in 2019 and repeated in 2022 and review new concepts (angiosomes and pressure injuries) and challenges due to the COVID-19 pandemic. METHODS: This survey captures participants' ranking of agreement or disagreement with 10 statements on Kennedy terminal ulcers, Skin Changes At Life's End, Trombley-Brennan terminal tissue injuries, skin failure, and unavoidable/avoidable pressure injuries. The survey was hosted online by SurveyMonkey from February 2022 until June 2022. All interested persons were able to participate in this voluntary, anonymous survey. RESULTS: Overall, 145 respondents participated. The same nine statements achieved at least 80% agreement (somewhat agree or strongly agree) as in the previous survey. The one statement that did not reach consensus also failed to reach consensus in the 2019 survey: "The concept of skin failure does not include pressure injuries." CONCLUSIONS: It is the authors' hope that this will stimulate more research into terminology and etiology of skin changes in persons at end of life and encourage more research regarding terminology and criteria to define which skin lesions are unavoidable or avoidable.

COVID-19 and Hospital-Acquired Pressure Injuries: A Systematic Review.

OBJECTIVE: To investigate the relationship between COVID-19 related variables and hospital-acquired pressure injuries (HAPI) incidence. DATA SOURCES: The authors searched four databases: Cochrane, MEDLINE, EMBASE, and CINAHL. The literature search contained key terms such as COVID-19, hospital-acquired pressure injuries, pressure ulcer, pressure injury, decubitus ulcer, and hospitalization. STUDY SELECTION: The systematic search of the literature identified 489 publications that matched the inclusion criteria. This included peer-reviewed publications that reported HAPI incidence for patients who were hospitalized and COVID-19 positive. Two reviewers performed the screen simultaneously and 19 publications were included. DATA EXTRACTION: Two reviewers followed a standardized extraction form that included study and patient characteristics, COVID-19 status, HAPI characteristics, prone positioning, length of hospitalization, and HAPI prevention and treatment strategies. DATA SYNTHESIS: A narrative synthesis of the extracted data was carried out because the data obtained were too heterogeneous for meta-analysis. The primary outcome was HAPI incidence. CONCLUSIONS: This review identified that HAPI incidence was high among men who were COVID-19 positive, had longer hospital stays, experienced prone positioning, and had care teams without a skin and wound care expert. Future research should employ more robust methodology and focus on quantitative modeling to iteratively improve in-patient HAPI guidelines.
