Advances in Skin & Wound Care最新文献

Background: High bacterial burden stalls wound healing and can quickly progress to infection and sepsis in complex, older-adult patients in long-term care (LTC) or skilled nursing facilities (SNFs).

Objective: To investigate the outcomes of point-of-care fluorescence (FL) imaging (MolecuLight i:X) of bacterial loads, which are frequently asymptomatic, to inform customized wound treatment plans for patients in LTC/SNFs.

Methods: In this retrospective pre/postinterventional cohort study, the authors compared the healing and infection-associated outcomes of 167 pressure injuries from 100 Medicare beneficiaries before and after implementation of FL imaging.

Results: Most patient demographics and wound characteristics did not differ significantly between the standard-of-care (SOC; n = 71 wounds) and FL (n = 96 wounds) cohorts. Significantly more wounds (+71.0%) healed by 12 weeks in the FL cohort (38.5%) versus the SoC cohort (22.5%). Wounds in the FL cohort also healed 27.7% faster (-4.8 weeks), on average, and were 1.4 times more likely to heal per Kaplan-Meier survival analysis (hazard ratio = 1.40; 95% CI, 0.90-2.12). Infection-related complications decreased by 75.3% in the FL cohort, and a significant shift from largely systemic to topical antibiotic prescribing was evidenced.

Conclusions: Fluorescence-imaging-guided management of wounds significantly improved healing and infection outcomes in highly complex and multimorbid patients in LTC/SNFs. Proactive bacterial infection management via local treatments was enabled by earlier, objective detection. These reported outcome improvements are comparable to randomized controlled trials and cohort studies from less compromised, selectively controlled outpatient populations. Fluorescence imaging supports proactive monitoring and management of planktonic and biofilm-encased bacteria, improving patient care in a complex, real-world setting.

Abstract: The human body possesses the unique ability to repair itself after injury through complex, sequential phases. Current development of advanced wound care therapies generally focuses on addressing a single aspect of this biological process that can result in delayed or ineffective wound healing. When patients present with further systemic and local confounding pathologies it can result in painful, chronic wounds that are especially challenging to treat.In this case report, the authors demonstrate how treatment with a novel multimodal wound matrix expedited healing and decreased pain in two patients who had each been unresponsive to treatment with advanced modalities for more than 7 months. The first patient had factor V Leiden and the second patient had sickle cell disease. Use of a once-weekly treatment protocol with the multimodal wound matrix, combined with sharp debridement when deemed clinically necessary, resulted in elimination of pain and expedited wound healing to closure. The wound matrix's omega fatty acid-based formulation is designed to target multiple factors common among hard-to-heal wounds that when not addressed, can adversely inhibit the wound-healing cascade.

Objective: To investigate the effects of tub bathing on the skin and bilirubin levels of newborns receiving tunnel and light-emitting diode phototherapy.

Methods: In this randomized controlled trial, hospitalized newborns diagnosed with hyperbilirubinemia treated with a tunnel or light-emitting diode device were randomly assigned to either the experimental (bath) or control (no bath) groups using a computer program. The skin integrity moisture balance of all groups was recorded using the Newborn Skin Condition Score at 6, 12, and 24 hours after phototherapy, and their total serum bilirubin measurements were evaluated.

Results: A statistically significant difference was observed in the babies' total serum bilirubin levels; this decrease was the highest in the experimental groups. Further, the skin integrity-moisture balance was higher in the experimental groups than in the control groups; it was highest in the tunnel-experimental group and lowest in the tunnel control group.

Conclusions: These results show that bathing is effective in reducing total bilirubin levels. This study adds to the evidence on skin integrity and moisture balance in newborns who were bathed during phototherapy.

Objective: To determine the prophylactic effect of hydrocolloid dressings on hypertrophic scarring in post-cesarean section wounds.

Methods: Patients who underwent cesarean section (C/S) at the authors' hospital and provided informed consent to participate were randomly assigned to the intervention and control groups. The intervention group commenced applying hydrocolloid dressings to the wound on postoperative day 7 or 8 and continued with weekly dressing changes for 6 months. The control group refrained from any dressing application but was followed up. In each group, the condition of the wound was evaluated 6 and 12 months postoperatively using the Japan Scar Workshop Scar Scale 2015, the Patient and Observer Scar Assessment Scale version 2.0, the modified Vancouver Scar Scale, and patient-reported outcomes.

Results: During this period, 135 patients underwent C/S at the authors' institution, and 47 (23 in the intervention group and 24 in the control group) were included in the analysis. In all assessment methods, the intervention group scored lower than the control group at 6 and 12 months after C/S. Twelve months after C/S, hypertrophic scarring (Japan Scar Workshop Scar Scale 2015 score of 6-15) was found in 14 of the 47 (29.8%) patients: 11 of 24 (45.8%) in the control group and 3 of 23 (13.0%) in the intervention group. The intervention's relative risk was 0.623 (95% CI, 0.417-0.930). The risk factor for hypertrophic scarring was midline vertical incision, with an odds ratio of 20.53 (95% CI, 4.18-100.92).

Conclusions: The study reveals that the application of hydrocolloid dressings to wounds reduces the risk of hypertrophic scarring after C/S.

Abstract: Intravenous plasminogen replacement therapy for patients with plasminogen deficiency type 1 (hypoplasminogenemia) was recently approved for marketing in the US. In this case report, the authors describe a 33-year-old man with hypoplasminogenemia who developed nonhealing postsurgical wounds following trauma to his right hand despite receiving standard treatment for 4 months. The patient was enrolled in a compassionate-use protocol with intravenous plasminogen replacement therapy and experienced prompt resolution of surgical wounds. He was the first human patient to receive replacement therapy with plasminogen, human-tvmh in the US and first to demonstrate cutaneous wound healing in addition to resolution of ligneous lesions attributable to plasminogen deficiency type 1.

Objective: To compare movement associated with position changes among nursing home residents who remain in lying versus upright positions for more than 2 hours and among residents living with obesity, dementia, or neither condition.

Methods: The authors conducted a descriptive exploratory study using secondary data (N = 934) from the Turn Everyone And Move for Ulcer Prevention (TEAM-UP) clinical trial to examine transient movements (<60 seconds) within prolonged periods of 2 to 5 hours without repositioning.

Results: Nursing home residents exhibit significantly more episodic transient movements when upright than lying. Residents with obesity or dementia exhibited similar frequencies of episodic transient movements compared with residents with neither obesity nor dementia. Upright or lying movements were more frequent among residents with obesity than among those with neither obesity nor dementia selectively when prolonged events ranged from 2 to 4 hours. Pairwise comparisons of movement rates among resident subgroups (living with obesity, living with dementia, or neither group) across repositioning intervals showed episodic transient movements were significantly higher across all subgroups for repositioning intervals up to 3 hours when compared with repositioning intervals of greater than 3 hours.

Conclusions: Findings challenge assumptions that nursing home residents are inactive and at risk for prolonged sitting. These preliminary findings, along with TEAM-UP findings where no pressure injuries occurred in up to 5 hours in prolonged positions, support establishing a standard 3-hour repositioning interval with use of high-density mattresses without a negative impact on pressure injury occurrence. There should be caution when considering repositioning intervals greater than 3 hours. Further research is indicated to explore protective effect of episodic transient movements of other subgroups.

Objective: To synthesize the literature on skin failure and pressure injuries among hospitalized patients with COVID-19.

Data sources: An electronic literature search using relevant keywords and controlled vocabulary was conducted in March 2023 on MEDLINE/PubMed, Embase, and CINAHL. Manual citation searches of included articles and grey literature, including the Wound, Ostomy, and Continence Nurses Society website were performed. Articles published in English between 2020 and April 2023 were considered.

Study selection: Articles were included if they reported on COVID-19 positive hospitalized adults with wounds that were not present upon admission. A total of 31 articles met these criteria.

Data extraction: Covidence was used to extract the data and was reviewed by multiple team members.

Data synthesis: Of the 31 studies, 27 reported new onset skin lesions during hospitalization. Wounds were classified as pressure injuries, skin failure, livedo racemosea and/or, retiform purpura, and associated with microvascular thrombosisthrombotic vasculopathy. Most pressure injuries were associated with prone position and affected patients often had multiple comorbidities including hypertension, diabetes mellitus, end-stage renal disease, heart disease, and COPD. Four articles highlighted an increased risk of new onset wounds, and three emphasized the importance of distinguishing deep tissue pressure injuries from ischemic-related lesions in patients with COVID-19.

Conclusions: The evidence suggests an increased risk of ischemic lesions and pressure injuries (PI) in patients with COVID-19 infection. This phenomenon may have inflated the numbers of PI during the pandemic and adversely affected nursing quality measures in acute care environments.
