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.

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.

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.

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.

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.

Early Malignant Melanoma Detection, Especially in Persons with Pigmented Skin.

GENERAL PURPOSE: To present a comprehensive gap analysis of podiatric melanoma literature. 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. Select the appropriate assessment techniques for screening patients, especially those with skin of color, for melanoma.2. Compare and contrast the various types of melanoma.3. Discuss the results of the literature review that offer insight to clinicians screening patients for melanoma.

Early detection of malignant melanoma is associated with better survival and clinical outcomes. Visual skin inspection is part of melanoma lesion assessment, but clinicians often have difficulty identifying lesions in persons with darker skin tones (eg, Fitzpatrick type 5 [brown] and type 6 [black] skin). There is also a lack of knowledge about the skin sites that are best to evaluate in persons with darkly pigmented skin (eg, the plantar surface of the feet, palms of the hand, and under the nail plate). These limitations can lead to a delay in diagnosis with potentially poor prognostic outcomes. In this article, the authors identify relevant literature to increase awareness for the presence of early signs of malignant melanoma in all skin types. Patient empowerment includes lifestyle adaptations, such as conducting regular skin and foot self-examinations to detect melanoma signs and applying sun protection on feet.

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.
