Journal of Wound Care Jun 2024The relationship between the healing time of pressure ulcers (PUs) and wound cleaning frequency among older people in homecare settings was investigated.
OBJECTIVE
The relationship between the healing time of pressure ulcers (PUs) and wound cleaning frequency among older people in homecare settings was investigated.
METHOD
This single-centre, prospective cohort study was conducted from April 2018 to March 2019. Patients who used home-visit nursing services, had National Pressure Ulcer Advisory Panel classification stage 2 PUs, and had their wounds cleaned at least twice a week were enrolled in the study. Wound cleaning was performed using tap water and a weakly acidic cleanser. Participants were divided into two groups, determined by the frequency of wound cleaning (twice weekly versus ≥3 times weekly). Duration of PU healing and the increase in care insurance premiums were compared in both groups.
RESULTS
A total of 12 patients were included in the study. The mean healing period of PUs cleaned ≥3 times per week (65.3±24.8 days) was significantly shorter than that of PUs cleaned twice a week (102.6±19.2 days; p<0.05). Furthermore, the increase in care insurance premiums for PUs cleaned ≥3 times per week (¥122,497±105,660 Yen per six months) was significantly lower than that for PUs cleaned twice a week (¥238,116±60,428 per six months) (p<0.05).
CONCLUSION
Our results suggest that frequent cleaning of PUs by health professionals in homecare settings not only shorten PU healing period but also reduces care insurance premiums for PU care.

BACKGROUND
Pseudo-Kaposi sarcoma (PKS) is a rare vascular proliferative disease, caused by arteriovenous malformation (AVM) and chronic venous insufficiency. The lesions are characterized by purple or reddish-brownish papules, plaques, and nodules. Although benign, it is clinically similar to Kaposi's sarcoma (KS), a malignant disease, and must be differentiated by histopathological examination. We report a rare case of PKS with chronic limb-threatening ischemia (CLTI).
CASE PRESENTATION
An 83-year-old man with diabetes mellitus (DM) presented to a local dermatology department with a complaint of a right second toe ulcer and was, thereby, referred to our department due to arterial bleeding during skin biopsy to exclude malignant diseases. Although the pulsation of dorsalis pedis artery of the affected limb was palpable, the skin perfusion pressure was only 20 and 30 mmHg on the dorsum and planter surface, respectively, indicating severe ischemia of toe and forefoot. Ultrasonography and computed tomography revealed an AVM around the right second metatarsophalangeal joint and occlusion of the right dorsalis pedis artery in the middle, indicating CLTI in the background. Pathological findings of the skin biopsy found capillary blood vessel proliferation, hemosiderin deposition, and extravascular red blood cell leakage in the dermal layer, which could be found in KS. However, CD34 was normally stained in the vascular endothelium, and human herpesvirus-8 staining was negative, resulting in the pathological diagnosis of PKS, a proliferative vascular lesion associated with AVM. The ulcer was spontaneously epithelialized, but 2 years later the ulcer recurred and infection developed, necessitating treatment for abnormal blood flow. Transarterial embolization using N-butyl 2-cyanoacrylate for the AVM controlled abnormal perfusion once; however, the procedure exacerbated perfusion of the toe, resulting in foot ulcer progression. Forefoot amputation with surgical excision of AVM was performed, and thereby, wound healing was achieved.
CONCLUSION
This is a rare case of PKS with CLTI complicated with AVM. As there is currently no established consensus on the treatment of PKS, the approach to treatment strategy should be tailored to the specific condition of each patient.

BACKGROUND
Tracheostomy-related acquired pressure injuries (TRPIs) are one of the hospital-acquired conditions. We hypothesize that an uneven ventilator circuit load, leading to non-neutral tracheostomy tube positioning in the immediate post-tracheostomy period, leads to an increased incidence of TRPIs. Does switching the ventilator circuit load daily, in addition to standard post-tracheostomy care, lead to a decreased incidence of TRPIs?
METHODS
This is a prospective quality improvement study. Study was conducted at two academic hospital sites within tertiary care hospitals at Emory University in different ICUs. Consecutive patients undergoing bedside percutaneous tracheostomy by the interventional pulmonary service were included. The flip the ventilator circuit (FLIC) protocol was designed and implemented in selected ICUs, with other ICUs as controls.
RESULTS
Incidence of TRPI in intervention and control group were recorded at post-tracheostomy day 5. A total of 99 patients were included from October 22, 2019, to May 22, 2020. Overall, the total incidence of any TRPI was 23% at post-tracheostomy day 5. Incidence of stage I, stage II, and stages III-IV TRPIs at postoperative day 5 was 11%, 12%, and 0%, respectively. There was a decrease in the rate of skin breakdown in patients following the FLIC protocol when compared with standard of care (13% vs. 36%; p = 0.01). In a multivariable analysis, interventional group had decreased odds of developing TRPI (odds ratio, 0.32; 95% CI, 0.11-0.92; p = 0.03) after adjusting for age, albumin, body mass index, diabetes mellitus, and days in hospital before tracheostomy.
CONCLUSIONS
The incidence of TRPIs within the first week following percutaneous tracheostomy is high. Switching the side of the ventilator circuit to evenly distribute load, in addition to standard bundled tracheostomy care, may decrease the overall incidence of TRPIs.

BACKGROUND
Pressure injuries are present in all healthcare environments and not only pose a significant health risk to individuals but also impose a heavy economic burden on society and families. Nurses, as the primary caregivers responsible for the prevention and management of pressure injuries, have knowledge that directly determines the incidence of pressure injuries.
AIM
To understand the current status of nurses' knowledge of pressure injuries in Shaanxi Province and the factors influencing it.
DESIGN
A cross-sectional survey.
METHODS
In April - May 2022, 16,599 nurses from hospitals at all levels in Shaanxi Province were selected as survey subjects by convenience sampling method. They were surveyed using the general information questionnaire and the Pieper-Zulkowski pressure injury Knowledge Questionnaire through the Questionnaire Star platform.
RESULTS
16,599 nurses had a pressure injury knowledge score of (44.32±10.11). Wound description and pressure ulcer staging dimensions were less than 60% correct. Comparison of pressure injury knowledge scores of nursing staff with different genders, hospital levels, titles, education, whether they were specialized nurses in wound stoma when they last attended a lecture on pressure ulcers, when they last read literature or books on pressure ulcers, and whether they ever looked for information about pressure ulcers on the Internet showed that the differences were statistically significant ( < 0.05), which were the influencing factors of the knowledge scores of the nursing staff in Shaanxi Province.
CONCLUSION
Clinical nurses' awareness of stress-related injuries still needs to be improved, and nursing administrators can improve the quality of pressure-related injury care by increasing nursing staff's awareness through continuing education, tiered training, and other measures.

Journal of Tissue Viability Jun 2024Pressure injuries (PI) are an important quality indicator in healthcare, we aimed to evaluate the relationship between PIs and ultrasonographic muscle mass measurements.
AIM
Pressure injuries (PI) are an important quality indicator in healthcare, we aimed to evaluate the relationship between PIs and ultrasonographic muscle mass measurements.
MATERIALS AND METHODS
This study was conducted prospectively between May 2022 and August 2022. The ultrasonography method was used for muscle mass measurement. The presence of PIs was assessed according to the PI classification system of the EPUAP (European Pressure Ulcer Advisory Panel), (NPIAP) National Pressure Ulcer Advisory Panel & PPPIA (Pan Pacific Pressure Injury Alliance).The demographics, age, sex, history of previous hospitalization, the place where patients are admitted (home/other service/intensive care unit), length of hospitalization, presence of a urinary catheter, diaper usage, and presence of tracheostomy were recorded.
RESULTS
Of the included 50 patients (mean age: 77.2 ± 9.7 (48-92), female: 56%), 42% had PIs, mostly staged 2 in the sacrum. The patients with PIs had significantly more urinary catheter and diaper usage, lower albumin levels, and reduced rectus femoris muscle thickness (RF MT) and rectus femoris cross-sectional area (RF CSA) values (p = 0.014, 0.018, 0.016, 0.018, and 0.042, respectively). In multivariate logistic regression analysis, RF MT was found independently associated with the PIs (p = 0.048).
CONCLUSION
Pressure injuries are more common in patients cared for in palliative care settings than in the general population and severely affect the quality of life. We found an independent relationship between PIs and RF MT. We consider that ultrasonographic muscle mass assessment may be a useful predictor of PIs.

To explore the knowledge, attitudes and practice (KAP) status of preventing pressure injury among clinical nurses working in paediatric ICU, and to examine factors affecting nurses' KAP. A questionnaire survey was conducted among 1906 paediatric ICU nurses in 18 children's hospitals by convenience sampling method. The survey tools were self-designed general data questionnaire, KAP questionnaire for the prevention of pressure injury and the influencing factors were analysed. A total of 1906 valid questionnaires were collected. The scores of overall KPA, knowledge, attitudes, and practice were 101.24 ± 17.22, 20.62 ± 9.63, 54.93 ± 5.81and 25.67 ± 6.76, respectively. The results of multiple linear regression analysis showed that education background, professional title, age and specialist nurse were the main influencing factor of nurses' knowledge of preventing PI; education background and specialist nurse were the main influencing factors of nurses' attitudes of preventing PI; knowledge, attitudes and education background were the main influencing factors of nurses' practice of preventing PI. Paediatric ICU nurses have a positive attitude towards the prevention of PI, but their knowledge and practice need to be improved. According to different characteristics of nurses, nursing managers should carry out training on the knowledge of prevention of PI to establish a positive attitude, so as to drive the change of nursing practice and improve the nursing practice level of ICU nurses to prevent of PI.

OBJECTIVE
Diabetic foot ulcer (DFU) is a severe complication with high mortality. High plantar pressure and poor microcirculation are considered main causes of DFU. The specific aims were to provide a novel technique for real-time measurement of plantar skin blood flow (SBF) under walking-like pressure stimulus and delineate the first plantar metatarsal head dynamic microcirculation characteristics because of life-like loading conditions in healthy individuals.
METHODS
Twenty young healthy participants (14 male and 6 female) were recruited. The baseline (i.e., unloaded) SBF of soft tissue under the first metatarsal head were measured using laser Doppler flowmetry (LDF). A custom-made machine was utilized to replicate daily walking pressure exertion for 5 min. The exerted plantar force was adjusted from 10 N (127.3 kPa) to 40 N (509.3 kPa) at an increase of 5 N (63.7 kPa). Real-time SBF was acquired using the LDF. After each pressure exertion, postload SBF was measured for comparative purposes. Statistical analysis was performed using the R software.
RESULTS
All levels of immediate-load and postload SBF increased significantly compared with baseline values. As the exerted load increased, the postload and immediate-load SBF tended to increase until the exerted load reached 35 N (445.6 kPa). However, in immediate-load data, the increasing trend tended to level off as the exerted pressure increased from 15 N (191.0 kPa) to 25 N (318.3 kPa). For postload and immediate-load SBF, they both peaked at 35 N (445.6 kPa). However, when the exerted force exceeds 35 N (445.6 kPa), both the immediate-load and postload SBF values started to decrease.
CONCLUSIONS
Our study offered a novel real-time plantar soft tissue microcirculation measurement technique under dynamic conditions. For the first metatarsal head of healthy people, 20 N (254.6 kPa)-plantar pressure has a fair microcirculation stimulus compared with higher pressure. There might be a pressure threshold at 35 N (445.6 kPa) for the first metatarsal head, and soft tissue microcirculation may decrease when local pressure exceeds it.

Review
To assess all published studies which describe what happens to the delivery of pressure ulcer/injury (PI/PU) care pathways as a result of detecting raised sub-epidermal moisture (SEM) delta (∆ ≥ 0.6). We undertook a systematic review of the literature, and included original research studies using either a prospective or retrospective study design that report the impact that assessment using SEM assessments have on healthcare practitioners' delivery of PI/PU care pathways in adults at risk of developing PI/PUs. The review protocol was registered on PROSPERO (CRD42023416975). A literature search was conducted in May 2023, using PubMed, CINAHL, Scopus, Cochrane, EMBASE, Web of Science and Science Direct databases. Data were extracted using a data extraction tool including elements such as country, setting, sample size, intervention, control and quality appraisal was undertaken using the Evidence-based Librarianship. We identified nine papers published between 2017 and 2022. The majority of these studies were conducted in England (n = 6; 67%). The systematic review included studies conducted across multiple care settings including acute care, medical-surgical units, and palliative care, highlighting the importance of PI/PU prevention and management across diverse patient populations. The PI/PU care pathways implemented in the studies varied, but commonly included elements such as the application or increased use of pressure-redistributing mattresses/cushions, implementation of repositioning plans, management of incontinence and moisture, regular skin inspection, and assessment of patient mobility. Out of the nine studies identified, seven reported PI/PU incidence. A meta-analysis of seven studies (N = 18 451) demonstrated a statistically significant reduction in visual PI/PU development in favour of SEM-guided care pathways compared to usual care (the odds ratio = 0.36 [95% confidence interval: 0.24-0.53, p < 0.00001]). This systematic review provides evidence that implementing SEM assessments in patients at risk of developing PI/PUs prompts anatomy-specific clinical actions. The subsequent implementation of enhanced and targeted skin care interventions leads to consistent and sustained reductions in hospital-acquired PU incidence. The findings emphasise the importance of incorporating SEM assessments as part of comprehensive PI/PU prevention strategies in all care settings and patient populations. This systematic review is limited by the predominance of observational studies and variable study quality. Future research should focus on randomised trials in different care settings that monitor the efficacy of preventive interventions and their impact in reducing PI/PU incidence when implemented based on SEM assessments.

Review
Noninvasive ventilation interfaces are one of the main factors contributing to pressure injuries caused by medical devices. Prevention is still the best course of action when discussing noninvasive ventilation-induced pressure injuries. A systematic review was designed to summarize and analyse all published literature on strategies to prevent pressure injuries caused by masks in patients undergoing noninvasive ventilation. The protocol of the systematic review followed the PRISMA guideline. An extensive search from the beginning to May 16, 2023, using current articles in databases such as Web of Science (WOS), Scopus, PubMed, and Cochrane Library was conducted. Medical Subject Headings (MESH) were used as follows: "Pressure Injury," "Noninvasive Ventilation," "Prevention," and "Pressure Sore." Any language-published studies that met the inclusion criteria were included in this review. A risk of bias assessment was conducted using the Joanna Briggs Institute tool, including evaluation methodologies for all studies. Database searches yielded 2546 articles, which were reduced to 23 that met our criteria after reviewing full texts. A narrative synthesis was conducted. As a result, type of interface (14 studies), dressings (4 studies), adjustment of mask leakage (1 study), humidity (1 study), positioning (1 study), and design of personalized masks (2 studies) seem to be a practical approach to prevent pressure injuries caused by masks in patients undergoing noninvasive ventilation. The results of our study show the effectiveness of preventive methods in reducing the incidence of pressure injuries caused by masks. Given the significant occurrence of pressure injury related to noninvasive ventilation and the crucial role of prevention and treatment, it is imperative to conduct more rigorous studies to ascertain the efficacy of each strategy.

Molecular evidence sterile tissue damage during pathogenesis of pododermatitis aseptica hemorrhagica circumscripta is associated with disturbed epidermal-dermal homeostasis.
Podermatitis aseptica hemorrhagica circumscripta is associated with metalloproteinase 2 weakening of distal phalangeal suspensory structures and sinkage of the distal phalanx in the claw capsule. Pressure from the tuberculum flexorium on the sole epidermis and dermis produces hemorrhagic tissue injury and defective horn production appearing as yellow-red, softened claw horn in region 4 of the sole. A model of the MAPK/ERK signal cascade orchestrating epidermal-dermal homeostasis was employed to determine if sterile inflammatory responses are linked to disturbed signal transduction for epidermal homeostasis in sole epidermis and dermis. The objective was to assess shifts in target genes of inflammation, up- and downstream MAPK/ERK signal elements, and targeted genes supporting epidermal proliferation and differentiation. Sole epidermis and dermis was removed from lateral claws bearing lesions of podermatitis aseptica hemorrhagica circumscripta, medial claws from the same limb and lateral claws from completely normal limbs of multiparous, lactating Holstein cows. The abundance levels of targeted transcripts were evaluated by real-time QPCR. Lesion effects were assessed by ANOVA, and mean comparisons were performed with t-tests to assess variations between mean expression in ulcer-bearing or medial claw dermis and epidermis and completely normal lateral claw dermis and epidermis or between ulcer-bearing dermis and epidermis and medial claw dermis and epidermis. The lesions were sterile and showed losses across multiple growth factors, their receptors, several downstream AP1 transcription components, CMYC, multiple cell cycle and terminal differentiation elements conducted by MAPK/ERK signals and β 4, α 6 and collagen 17A hemidesmosome components. These losses coincided with increased cytokeratin 6, β 1 integrin, proinflammatory metalloproteinases 2 and 9, IL1B and physiologic inhibitors of IL1B, the decoy receptor and receptor antagonist. Medial claw epidermis and dermis from limbs with lateral claws bearing podermatitis aseptica hemorrhagica circumscripta showed reductions in upstream MAPK/ERK signal elements and downstream targets that paralleled those in hemorrhagic lesions. Inhibitors of IL1B increased in the absence of real increases in inflammatory targets in the medial claw dermis and epidermis. Losses across multiple signal path elements and downstream targets were associated with negative effects on targeted transcripts supporting claw horn production and wound repair across lesion-bearing lateral claws and lesion-free medial claw dermis and epidermis. It was unclear if the sterile inflammation was causative or a consequence of these perturbations.
