ABSTRACT
The development of pressure ulcers, associated with increased temperature and moisture in specific areas of the body, and the risk of microbial infections in patients lying in a static position for prolonged periods of time represents a serious issue in medicine. In order to prevent the formation of pressure ulcers, this work aims to present advanced nanostructured coatings developed by three research groups. Nanometric silver, ash and functionalized torrefied biomass were the basis for the treatment of wound dressings to improve thermal conductivity and antimicrobial properties of the conventional cotton gauzes. Each treatment was performed according to its own optimized method. The treated fabrics were characterized in terms of antimicrobial properties, heat transfer, morphology and hydrophobic behavior. The results demonstrated the effectiveness of the deposition treatments also in synergistic actions. In particular, the antibacterial efficacy was improved in all the samples by the addition of silver treatment, and the thermal conductivity was enhanced by around 58% with nanometric ashes. A further step of the study involved the designing of two multilayer systems evaluated using circuit models for determining the total thermal conductivity. In this way, both systems were designed with the aim to guarantee simultaneous efficacy: high antibacterial and hydrophilic properties at the skin level and more hydrophobic and conductive behaviors toward the external environment.
ABSTRACT
Pressure ulcers (PU) are caused by persistent long-term pressure, which compromises the integrity of the epidermis, dermis, and subcutaneous adipose tissue layer by layer, making it difficult to heal. Platelet products such as platelet lysate (PL) can promote tissue regeneration by secreting numerous growth factors based on clinical studies on skin wound healing. However, the components of PL are difficult to retain in wounds. Gelatin methacrylate (GelMA) is a photopolymerizable hydrogel that has lately emerged as a promising material for tissue engineering and regenerative medicine. The PL liquid was extracted, flow cytometrically detected for CD41a markers, and evenly dispersed in the GelMA hydrogel to produce a surplus growth factor hydrogel system (PL@GM). The microstructure of the hydrogel system was observed under a scanning electron microscope, and its sustained release efficiency and biological safety were tested in vitro. Cell viability and migration of human dermal fibroblasts, and tube formation assays of human umbilical vein endothelial cells were applied to evaluate the ability of PL to promote wound healing and regeneration in vitro. Real-time polymerase chain reaction (PCR) and western blot analyses were performed to elucidate the skin regeneration mechanism of PL. We verified PL's therapeutic effectiveness and histological analysis on the PU model. PL promoted cell viability, migration, wound healing and angiogenesis in vitro. Real-time PCR and western blot indicated PL suppressed inflammation and promoted collagen I synthesis by activating STAT3. PL@GM hydrogel system demonstrated optimal biocompatibility and favorable effects on essential cells for wound healing. PL@GM also significantly stimulated PU healing, skin regeneration, and the formation of subcutaneous collagen and blood vessels. PL@GM could accelerate PU healing by promoting fibroblasts to migrate and secrete collagen and endothelial cells to vascularize. PL@GM promises to be an effective and convenient treatment modality for PU, like chronic wound treatment.

Hospital-acquired pressure ulcers (HAPUs) are still an important worldwide issue related to the safety and quality of patient care, which are among the top five adverse events reported. Patients who develop HAPUs have longer stays in the hospital than necessary, are at a greater risk of infections, and are more likely to die. Surgical patients are prone to developing PUs because they often remain immobile for extended periods of time, and their surgical procedures may limit the flow of blood oxygen and nutrition and lead to a decrease in muscle tone. Mesenchymal stem cells (MSCs) represent an attractive stem cell source for tissue regeneration in clinical applications, which have been demonstrated to improve wound healing through re-epithelialization, increased angiogenesis, and granulation tissue formation. Here, we present the case of an emergency surgical patient who developed an ulcer on the right heel during hospitalization. The human umbilical cord Wharton's jelly-derived MSCs (WJ-MSCs) re-suspended in platelet-rich plasma (PRP) were injected into ulcer margins. Four days after the WJ-MSC application, the patient showed progressive healing of the PU. From days 4 to 33, granulation tissue formation and re-epithelialization were clearly observed. The ulcer was almost healed completely on day 47, and the pain in the patient's wound area also decreased. Thus, intradermal transplantation of WJ-MSCs and PRP was safe and effective for treatment in patients with pressure ulcers. WJ-MSCs, together with PRP, may offer a promising treatment option for wound healing.
ABSTRACT
AIM: Individuals in the community with reduced mobility are at risk of exposure to prolonged lying and sitting postures, which may cause pressure ulcers. The present study combines continuous pressure monitoring technology and intelligent algorithms to evaluate posture, mobility, and pressure profiles in a cohort of community dwelling patients, who had acquired pressure ulcers. MATERIALS AND METHODS: This study represents a secondary analysis of the data from the Quality Improvement project 'Pressure Reduction through COntinuous Monitoring In the community SEtting (PROMISE)'. 22 patients with pressure ulcers were purposely selected from 105 recruited community residents. Data were collected using a commercial continuous pressure monitoring system over a period of 1-4 days, and analysed with an intelligent algorithm using machine learning to determine posture and mobility events. Duration and magnitude of pressure signatures of each static posture and exposure thresholds were identified based on a sigmoid relationship between pressure and time. RESULTS: Patients revealed a wide range of ages (30-95 years), BMI (17.5-47 kg/m2) and a series of co-morbidities, which may have influenced the susceptibility to skin damage. Posture, mobility, and pressure data revealed a high degree of inter-subject variability. Largest duration of static postures ranged between 1.7 and 19.8 h, with 17/22 patients spending at least 60 % of their monitoring period in static postures which lasted >2 h. Data revealed that many patients spent prolonged periods with potentially harmful interface pressure conditions, including pressure gradients >60 mmHg/cm. CONCLUSION: This study combined posture, mobility, and pressure data from a commercial pressure monitoring technology through an intelligent algorithm. The community residents who had acquired a pressure ulcer at the time of monitoring exhibited trends which exposed their skin and subdermal tissues to prolonged high pressures during static postures. These indicators need further validation through prospective clinical trials.
ABSTRACT
BACKGROUND: Pressure ulcer (PU) are prevalent among critically ill trauma patients, posing substantial risks. Bundled care strategies and silver nanoparticle dressings offer potential solutions, yet their combined effectiveness and impact on patient satisfaction remain insufficiently investigated. AIM: To assess the impact of bundled care along with silver nanoparticle dressing on PUs management and family satisfaction in critically ill trauma patients. METHODS: A total of 98 critically ill trauma patients with PUs in intensive care unit (ICU) were included in this study. Patients were randomly assigned to either the control group (conventional care with silver nanoparticle dressing, n = 49) or the intervention group (bundled care with silver nanoparticle dressing, n = 49). The PU Scale for Healing (PUSH) tool was used to monitor changes in status of pressure injuries over time. Assessments were conducted at various time points: Baseline (day 0) and subsequent assessments on day 3, day 6, day 9, and day 12. Family satisfaction was assessed using the Family Satisfaction ICU 24 questionnaire. RESULTS: No significant differences in baseline characteristics were observed between the two groups. In the intervention group, there were significant reductions in total PUSH scores over the assessment period. Specifically, surface area, exudate, and tissue type parameters all showed significant improvements compared to the control group. Family satisfaction with care and decision-making was notably higher in the intervention group. Overall family satisfaction was significantly better in the intervention group. CONCLUSION: Bundled care in combination with silver nanoparticle dressings effectively alleviated PUs and enhances family satisfaction in critically ill trauma patients. This approach holds promise for improving PUs management in the ICU, benefiting both patients and their families.
ABSTRACT
Introduction Pressure ulcers, also known as bedsores, are a significant concern for bedridden individuals, presenting both physical and socioeconomic challenges. Factors such as prolonged immobility, chronic medical conditions, and poor nutrition contribute to their development. Despite extensive research in some regions, studies comparing diabetic and non-diabetic populations remain limited, particularly in low-income settings. This study aimed to investigate the risk factors and frequency of pressure ulcers among bedridden patients, addressing this gap in understanding and guiding targeted interventions. Materials and methods A cross-sectional study was conducted across four government hospitals in Peshawar, Pakistan. A total of 388 bedridden patients with pressure ulcers were included, and data were collected through a questionnaire. The questionnaire covered demographics, comorbidities, duration of bedbound status, BMI, and caregivers' awareness of pressure ulcer care. Data analysis was performed using SPSS version 22.0 (Armonk, NY: IBM Corp.), with qualitative data presented as frequencies and percentages and quantitative data as mean and standard deviation. Chi-square tests were utilized for significance, with p<0.05 considered significant. Results Of the 388 patients analyzed, 230 (59.3%) were diabetic, highlighting the prevalence of diabetes among pressure ulcer cases. The majority of diabetic patients with ulcers were over 41 years old, and 293 (75.5%) had comorbidities. Surgical intervention was the primary cause of ulcers in 213 (54.8%) cases, followed by stroke in 77 (19.8%) cases. Notably, 252 (65%) of caregivers exhibited inadequate knowledge regarding ulcer care. Stage II ulcers were prevalent in both diabetic and non-diabetic cohorts. Conclusions Pressure ulcers are poorly controlled complications observed in bedridden individuals, highlighting a critical need for comprehensive preventive measures and caregiver education to alleviate the burden of pressure ulcers, especially in diabetic patients. Factors such as prolonged immobility, surgical interventions, and insufficient caregiver knowledge contribute to the development of pressure ulcers. Understanding these complexities is essential for implementing effective care approaches and mitigating the impact of pressure ulcers.
ABSTRACT
This study aimed to determine the prevalence of adverse events in mechanically ventilated adults with COVID-19 who have undergone prone positioning. A total of 100 patients were included retrospectively; 60% were males, the mean age was 64.8 ± 9.1 years, and hospital mortality was 47%. In all, we recorded 118 removals of catheters and tubes in 66 patients; 29.6% were removals of a nasogastric tube, 18.6% of an arterial line, 14.4% of a urinary catheter, and 12.7% of a central venous catheter. Reintubation or repositioning of a tracheotomy tube was required in 19 patients (16.1%), and cardiopulmonary resuscitation in 2 patients (1.7%). We recorded a total of 184 pressure ulcers in 79 patients (on anterior face in 38.5%, anterior thorax in 23.3% and any extremity anteriorly in 15.2%). We observed that body weight (p = 0.021; ß = 0.09 (CI95: 0.01-0.17)) and the cumulative duration of prone positioning (p = 0.005; ß = 0.06 (CI95: 0.02-0.11)) were independently associated with the occurrence of any adverse event. The use of prone positioning in our setting was associated with a greater number of adverse events than previously reported. Body weight and cumulative duration of prone positioning were associated with the occurrence of adverse events; however, other factors during a COVID-19 surge, such as working conditions, staffing, and staff education, could also have contributed to a high prevalence of adverse events.
ABSTRACT
BACKGROUND: Nurses' knowledge of pressure injuries causes and risk factors helps to prevent their occurrences and protect the patient. AIM: To assess the level of knowledge of medical device-related pressure injuries and to identify risk factors that affect the knowledge. METHODS: A cross-sectional design was used in this study considering a convenience sample from critical care nurses. The nurses were invited to complete the Medical Device-Related Pressure Injuries Knowledge Questionnaire. RESULTS: About 71 nurses participated in the study. The mean score of MDRPI_KQ was 23.28 ± 4.14 out of 36. Mann-Whitney Test did not show statistically significant relationships between the MDRPI_KQ mean score and related variables (p > 0.05). The regression results indicated that the three predictors explained 46.4% of the variance (R2 = 0.215, F(3, 6.114) = 3.75, p = 0.001). It was found that the Frequency of encountering a patient with MDRPIs significantly predicted MDRPI_KQ score, job position, and assuming the care responsibility for MDRPIs in the department. CONCLUSIONS: Poor knowledge of pressure injuries can negatively affect patient care so training programs and policies should be developed based on the level of knowledge and practices of the staff to be more effective.
ABSTRACT
Pressure ulcers, or bedsores, are created by areas of the skin under prolonged pressure and can lead to skin and underlying tissue damage. The present study evaluated the effects of carboxymethyl cellulose/sodium alginate/gelatin (CMC/Alg/Gel) hydrogel containing doxycycline (DOX) on improving the healing process of pressure ulcers. The magnet was used to apply pressure on the dorsum skin rat to induce a pressure ulcer model. Then sterile gauze, CMC/Alg/Gel, and CMC/Alg/Gel/1% w/v DOX hydrogels were used to cover the wounds. Blood compatibility, weight loss, cytocompatibility, drug release rate, cell viability, wound closure, and re-epithelialization were evaluated in all animals on the 14th day after treatment. In vivo results and histopathological evaluation showed 56.66% wound closure and the highest re-epithelialization in the CMC/Alg/Gel/1% w/v DOX hydrogel group (14 days after treatment). Furthermore, real-time PCR results indicated that the hydrogel containing DOX significantly decreased the expression of the MMP family consisting of MMP2 and MMP9 mRNA and also increased the expression of vascular endothelial growth factor VEGF mRNA. This study suggested that the addition of DOX, an antibiotic and MMP inhibitor, to hydrogels may be effective in the healing process of pressure ulcers.
ABSTRACT
Background: People with spinal cord injury (SCI) are at high risk of developing pressure injuries. Reports in the SCI-community had indicated that a new class of wound treatment, MPPT (micropore-particle-technology), was effective in treating pressure injuries. The British Spinal Injuries Association therefore conducted a survey among MPPT-users to learn from their experiences. Methods: Online survey restricted to individuals with spinal cord injury. Participants were requested to identify themselves to permit validation of statement. Results: The survey had 41 respondents reporting on a total of 49 wounds of which the two main categories were wounds (n = 33), primarily pelvic pressure ulcers; and draining fistulas (n = 9) caused by osteomyelitis. All wounds reported had reached full closure. Median duration of MPPT use and time to closure were 3 and 4 weeks for acute wounds (<6 weeks old) and 8 and 10 weeks for chronic wounds, respectively. On draining fistulas, MPPT had been used to reduce wound size, remove soft tissue infection, avoid sepsis, reduce autonomic dysreflexia, improve overall health, and avoid bed rest, whilst waiting for surgery. Comments on MPPT were 84% highly positive, 11% positive, and 0% negative. No adverse events were reported. Conclusions: MPPT achieved a 100% closure rate of acute and chronic wounds, and, in draining fistulas, effectively controlled soft tissue infection resulting from osteomyelitis. MPPT does not require bed rest and is suitable for self-care and telemedicine, promoting independence and higher quality-of-life. The findings strongly agree with a recent clinical study of MPPT.
ABSTRACT
The annual cost to the NHS of managing 3.8 million patients with a wound was estimated in 2020 to be £8.3 billion, of which £5.6 billion was spent on the 30% of wounds that did not heal and £2.7 billion on the 70% of wounds that healed (Guest, 2020). One of the main symptoms associated with chronic 'hard-to-heal' wounds is the production of excess exudate (Atkin et al, 2019). This is due to a prolonged chronic inflammatory response stimulated by a physiological cause. This article describes what exudate is and its importance in the wound healing process, highlighting the consequences of too little or excessive wound exudate associated with any wound. The article goes on to describe a case series observational study involving a range of patients (n=47; 33 male/14 female), aged between 33 and 91 years (mean 67.4 years), with a variety of acute (n=11) and chronic exuding wounds (n=44). In total, 55 wounds of various aetiologies were managed with DryMax Super (a dressing whose design includes superabsorbent polymers) in order to evaluate and report on the absorption and fluid-handling properties of the product.

OBJECTIVE: To compare the transcutaneous oxygen pressure (tcpO2) measurement values and changes in compressed areas of surgical patients before and after surgery and to explore the related factors influencing the tcpO2 changes before and after surgery. METHODS: Researchers selected 100 patients who underwent elective surgery in a tertiary comprehensive hospital from November 2021 to September 2022. A self-designed general information questionnaire was used to collect patient general information and disease-related data, including gender, age, smoking and drinking history, hypertension, diabetes, local skin temperature and humidity, related biochemical indicators, and activities of daily living score. Researchers used a transcutaneous oxygen pressure meter to measure and record the tcpO2 of the compressed areas (sacrococcygeal area, scapula area, and heel area) before and after surgery. RESULTS: Among the 100 patients, 37.00 % (37/100) developed type I/II pressure ulcers after surgery, and 30 patients (81.08 %) showed regression within 2 h after surgery. There was no statistically significant difference in the preoperative tcpO2 measurement values of the scapula and heel areas between the group with and without pressure ulcers, but the preoperative tcpO2 measurement value of the sacrococcygeal area in the group without pressure ulcers was higher than that in the group with pressure ulcers (P < 0.01). The factors affecting the preoperative tcpO2 measurement value of the sacrococcygeal area were smoking and surgical type. After surgery, the tcpO2 measurement values of the three areas in the group with pressure ulcers were significantly lower than those in the group without pressure ulcers (P < 0.01). Comparing the tcpO2 values of different areas, it was found that the tcpO2 value was lowest in the sacrococcygeal area, followed by the heel area, and the tcpO2 value in the scapula area was highest both before and after surgery (P < 0.01). The main factors affecting the postoperative tcpO2 measurement value were diabetes, Glassgow score, surgical time, and intraoperative red blood cell transfusion. CONCLUSION: The measurement of tcpO2 is related to the incidence of surgically acquired pressure ulcers, and this technology may become an important tool for quantitative assessment of the risk of pressure ulcers.

BACKGROUND: Pressure ulcers pose significant challenges in terms of treatment, often exhibiting a low success rate and a propensity for recurrence. Children with neurological impairments such as myelomeningocele and those with spinal injuries are particularly vulnerable to developing pressure ulcers. Despite advancements, achieving successful reconstruction remains a formidable task. Common sites prone to pressure ulcer formation include the sacral and ischial regions, as well as areas over bony prominences. Additionally, pressure ulcers attributable to medical devices facilitating ambulation are observed. While many pressure sores resolve spontaneously, conservative management may prove ineffective for some, especially in cases of stage 3 and 4 ulcers, necessitating surgical intervention. Various surgical techniques are employed for the treatment of decubitus ulcers, yet there exists no universally accepted gold standard for their management. This paper presents our institutional experience in this domain, highlighting differences in surgical approaches, treatment outcomes, complication rates, and long-term follow-up. METHODS: This study involved a retrospective analysis of medical records from 11 children, ranging in age from 10 to 17 years, who presented with extensive pressure ulcers that were unresponsive to conservative treatment measures. Data collection spanned from February 2017 to June 2022. The pressure ulcers affected various anatomical regions, including the ischial area (5/11 patients), sacral region (3/11 patients), lower limb (1/11 patients), elbow (1/11 patients), and perineal area (1/11 patients). Surgical intervention was the chosen approach for all cases, employing techniques such as reconstructive surgery utilizing perforator, pediculated flaps, and locoregional flaps. RESULTS: Eleven patients with sore ulcers (stage 3 and 4) were treated surgically. We present our experience of using surgical methods, including pedicled anterolateral flaps, pedicled gracilis musculocutaneous flaps, propeller flaps and locoregional flaps. In some cases, surgery was performed after 60 days of hospitalization or ten years after ulcer occurrence. We reviewed the length of hospital stay, surgical management and patient satisfaction. Patients were followed up to 5 years post-surgery. All flaps survived except for one flap where partial necrosis was observed. The recurrence rate was 9.01% (1/11). One patient underwent another surgery. The general outcome was satisfactory. CONCLUSIONS: Conclusions: Our findings underscore the efficacy of flap reconstruction surgical techniques in the management of pressure ulcers among pediatric patients. Based on our experience and the outcomes observed, we advocate for considering reconstructive surgery as a viable therapeutic option early in the treatment course, particularly for stage 3 and 4 ulcers. This approach not only addresses the immediate needs of patients but also holds promise for long-term wound healing and prevention of recurrence.
ABSTRACT
AIM: The objective of the present study is twofold: to describe the prevalence and incidence of pressure ulcers (PUs) among ICU patients during the COVID-19 pandemic, and to identify the risk factors associated with the development of PUs in this cohort of ICU patients. MATERIALS AND METHODS: Retrospective cohort study of adult critical care patients admitted in two general ICUs of two different countries (Sweden and Portugal) between March 1st, 2020, and April 30th, 2021, through the analysis of the electronic health record database. The prevalence and incidence were calculated, and a multivariate logistic-regression model was used to calculate odds ratios (ORs), of possible risk factors of PU development. RESULTS: The sample consisted of 1717 patients. The overall prevalence of PU was 15.3 %, and the incidence of ICU-acquired PUs was 14.1 %. Most of the pressure ulcers documented in this study were at the anterior part of the body (45.35 %) and regarding classification, Category 2 (38.40 %) and Category 3 (22.71 %) pressure ulcers together accounted for over fifty percent of the cases recorded. In the multivariate logistic regression model for PU, age, having COVID-19 (OR = 1.58, 95 % CI: 1.20-2.09), use of mechanical ventilation (OR = 1.49, 95 % CI: 1.13 = 1.97), use of vasopressors (OR = 1.31, 95 % CI: 1.00-1.70), having a Braden risk score ≤16 at admission (OR = 1.63; 95 % CI: 1.04-2.56), and length of stay (LOS) (OR = 1.43, 95 % CI 1.03-2.00 if LOS 90-260 h, OR = 2.34, 95 % CI: 1.63-3.35 if LOS >260 h) were associated with the likelihood of developing an ICU-acquired PUs. CONCLUSION: When adjusted for covariates patients with COVID-19 had a higher risk for PU development during the ICU stay compared to patients without COVID-19. Health care personnel in ICU may consider incorporating COVID-19, age, use of mechanical ventilation, vasopressors and estimated LOS in addition to a comprehensive risk assessment including both a risk score and clinical assessment.
ABSTRACT
Pressure ulcers (PUs) represent a burden to the health economy and patients alike. Despite national and international guidelines regarding the management of risk, the incidence and prevalence across England remains high. Detecting early the risk of PUs is paramount, and requires using a valid risk assessment tool alongside clinical judgement and management of associated risk factors. There is a need to implement prevention strategies. Introducing care bundles for pressure ulcers, for example SKIN, SSKIN and most recently aSSKINg, is designed to guide clinicians and reduce variations in care. This article presents a review of the evidence on compliance with guidelines, frameworks, pathways or care bundles within primary and secondary care settings. This article focuses on the literature review that was conducted to inform a subsequent clinical audit of compliance with the aSSKINg framework in a Community NHS Foundation Trust in the South East of England.

Pressure ulcers carry a significant risk in clinical practice. This paper proposes a practical and interpretable approach to estimate the risk levels of pressure ulcers using decision tree models. In order to address the common problem of imbalanced learning in nursing classification datasets, various oversampling configurations are analyzed to improve the data quality prior to modeling. The decision trees built are based on three easily identifiable and clinically relevant pressure ulcer risk indicators: mobility, activity, and skin moisture. Additionally, this research introduces a novel tabular visualization method to enhance the usability of the decision trees in clinical practice. Thus, the primary aim of this approach is to provide nursing professionals with valuable insights for assessing the potential risk levels of pressure ulcers, which could support their decision-making and allow, for example, the application of suitable preventive measures tailored to each patient's requirements. The interpretability of the models proposed and their performance, evaluated through stratified cross-validation, make them a helpful tool for nursing care in estimating the pressure ulcer risk level.
ABSTRACT
PURPOSE: Injuries of the nasal vestibular skin caused by the rotating burr shafts can represent a tedious complication following endonasal drilling and is experienced sooner or later by every rhino-surgeon. MATERIAL AND METHODS: To protect the nasal entrance from laceration by the free rotating drill shaft we position an otology speculum in the nasal entrance. The speculum is held in place by the scrub nurse during the critical phase of bone drilling. RESULTS: Following the introduction of the ear speculum protection, we successfully treated our dacryocystostamia procedures (n = 27) and median maxillectomia procedures (n = 6) without any further soft tissue erosions. DISCUSSION: Preventive measures for injuries by endonasal drilling procedures are not reported extensively in literature. This stands in contrast to the fact that these injuries are prone to cause significant suffering as amply described in the case of nostril laceration due to nasogastric intubation or nasogastric feeding tubes. CONCLUSION: The use of a readily available, reusable ear speculum in endonasal drill application eliminated the complication of nasal entrance lacerations throughout our institution, hitherto.

Chronic wounds pose a significant threat to human health, particularly for the elderly, and require extensive healthcare resources globally. Autophagy, a key molecular player in wound healing, not only offers a defense against infections but also contributes to the deposition of the extracellular matrix during the proliferative phase. Additionally, it promotes the proliferation and differentiation of endothelial cells, fibroblasts, and keratinocytes. We have recently shown that applying magnetized saline water topically can trigger autophagy in intact skin. In this case series, we document the successful management of five non-infected, difficult-to-heal wounds in elderly patients using a topical autophagy-stimulating gel containing 95% magnetized saline water. The treated wounds included pressure ulcers, venous ulcers, and trauma-related injuries that had shown minimal or no improvement with standard wound therapies over a prolonged period. Application of the autophagy-stimulating gel promoted wound healing, as indicated by reduced fibrous and necrotic tissue, granulation tissue formation, re-epithelialization, and partial or complete wound closure. These preliminary case studies suggest that a topical gel containing magnetized saline water, which promotes autophagy, may aid healing of chronic wounds in elderly patients. Further investigation is warranted to explore the potential of this novel approach, as it may offer a valuable addition to the existing arsenal of wound care treatments for the aging population, particularly in addressing difficult-to-heal wounds.
ABSTRACT
Pressure injuries are a significant concern for patients undergoing neurosurgical procedures due to prolonged immobility and the complexity of care. This study evaluates the efficacy of standardized pressure ulcer management protocols in preventing pressure injuries and enhancing patient care in a neurosurgical context. A comprehensive retrospective analysis was conducted at a single institution from December 2020 to December 2023, comparing 50 patients who received standardized pressure ulcer management (intervention group) with 50 patients who received conventional care (control group). The study assessed the incidence of pressure ulcers, patient comfort levels using the Kolcaba Comfort Scale and sleep quality using the Richards-Campbell Sleep Questionnaire (RCSQ). Statistical analysis was performed using SPSS software, version 27.0, applying t-tests and chi-square tests as appropriate. The intervention group exhibited a significantly lower incidence of pressure ulcers at all measured time points post-surgery compared to the control group. Patient comfort levels in the intervention group were consistently higher across psychological, environmental, physiological and socio-cultural domains. Sleep quality metrics, including sleep depth, latency to sleep onset and overall sleep quality, were significantly improved in the intervention group. The implementation of standardized pressure ulcer management protocols in neurosurgical care significantly reduces the incidence of pressure injuries, enhances patient comfort and improves sleep quality. These findings highlight the importance of adopting structured care protocols to improve postoperative outcomes and patient well-being in neurosurgical settings.

Background: The clinical appearance of acral melanoma is diverse and can cause diagnostic difficulties in individual cases. Case description: We present a clinical case of an 83-year-old patient with a melanoma in the heel area that was initially interpreted as a pressure ulcer, resulting in delayed and more complicated treatment. Conclusions: Melanomas should be included in the differential diagnosis even in "typical" pressure ulcer areas. Against the background of increasingly poor healthcare in rural areas, an increase in such cases can be expected.
