Activated Charcoal-Alginate Platform for Simultaneous Local Delivery of Bioactive Agents: At the Nexus of Antimicrobial and Cytotoxic Activity of Zn2+ Ions

Antimicrobial resistance (AMR) is a global public health threat that affects cancer patients more than the general population. In this work, a composite system based on Zn-alginate hydrogel and activated charcoal (AC) particles that, upon contact with physiological fluids, simultaneously releases bioactive agents (Zn2+ and AC particles impregnated with povidone-iodine) was designed to locally address specific problems characteristic for malignant wounds (MWs). This composite was comprehensively investigated in vitro regarding its morphology (field-emission scanning electron microscopy), Zn2+ release (flame atomic absorption spectrometry), iodine adsorption and desorption from AC particles (energy dispersive X-ray analysis and UV-visible spectroscopy) as well as its antimicrobial and antitumor activity. With respect to the ongoing AMR crises, antimicrobial activity was tested against a wide range of wild multi-drug resistant bacterial and yeast strains, all isolated from patient wounds. Since Zn2+ ions proved to be selectors of resistant strains of bacteria, the synergistic activity of AC particles and adsorbed iodine was shown to be crucial for excellent antibacterial activity. On the other hand, the synergy of AC particles and Zn2+ ions showed an equally strong antifungal effect. In addition, antimicrobial concentrations of Zn2+ ions showed cytotoxic activity against two cancer cell lines derived from cancers affecting skin either as metastatic cancer (breast cancer MDA-MB-453 cell line) or primary cancer of the skin (malignant melanoma Fem-X cell line), which enables Zn2+ ions to be further investigated as potent local agents targeting malignant cells.

pH factors in chronic wound and pH-responsive polysaccharide-based hydrogel dressings

Chronic wounds present a significant healthcare challenge marked by complexities such as persistent bleeding, inhibited cell proliferation, dysregulated inflammation, vulnerability to infection, and compromised tissue remodeling. Conventional wound dressings often prove inadequate in addressing the intricate requirements of chronic wound healing, leading to slow healing and heightened susceptibility to infections in patients with prolonged medical conditions. Bacterial biofilms in chronic wounds pose an additional challenge due to drug resistance. Advanced wound dressings have emerged as promising tools in expediting the healing process. Among these, pH-responsive polysaccharide-based hydrogels exhibit immense prospect by adapting their functions to dynamic wound conditions. Despite their potential, the current literature lacks a thorough review of these wound dressings. This review bridges this gap by meticulously examining factors related to chronic wounds, current strategies for healing, and the mechanisms and potential applications of pH-responsive hydrogel wound dressings as an emerging therapeutic solution. Special focus is given to their remarkable antibacterial properties and significant self-healing abilities. It further explores the pH-monitoring functions of these dressings, elucidating the associated pH indicators. This synthesis of knowledge aims to guide future research and development in the field of pH-responsive wound dressings, providing valuable insights into their potential applications in wound care.

Quality of Life in Patients with Malignant Wounds Treated at a Wound Care Clinic

Background

Malignant wounds can present in up to 14.5% of patients with advanced cancer, significantly reducing quality of life (QoL). Management of malignant wounds is generally palliative, with the goal of improving or maintaining QoL. There is a lack of data on the impact of wound care clinics on QoL in patients with malignant wounds.

Objectives

We sought to assess the QoL in patients with malignant wounds attending a wound care clinic. We also aimed to describe the baseline QoL, trends in QoL, physical symptoms, and treatment modalities that affect QoL in patients with malignant wounds over time.

Methods

This retrospective observational study included 36 patients attending a wound care clinic at an oncologic hospital from 1/1/2016-4/1/2023. As part of the standard of care, these patients complete a Skindex-16 QoL survey at each visit. The Skindex-16 is a validated instrument to measure the effects of skin diseases on QoL. Data were extracted from the electronic medical record. Descriptive statistics, graphical methods, and random effects models for change were used to describe the patient population and the QoL measures over time.

Results

Of the 36 patients who completed at least one Skindex-16 questionnaire, 69.4% were female, and 50.0% developed malignant wounds from breast cancer, 30.5% from nonmelanoma skin cancer, and 8.3% from sarcoma. At the initial visit, 86.1% of patients had exudate associated with their malignant wound, 52.7% of patients had malodor, 63.9% had bleeding, 69.4% had pain, and 50% had pruritus. The mean baseline Skindex-16 score was 54.5, falling into the "extremely severe" category, with a mean score of 15.4, 18.8, and 20.3 for the symptoms, emotions, and functioning domains, respectively. Nineteen patients completed at least one additional Skindex-16 questionnaire at follow-up visits (visit two 52.8%, visit three 33.3%, visit four 19.4%, visit five or greater 13.9%). Compared to the mean Skindex-16 score at baseline, there was an 18.5 point improvement at visit 2 (95% CI: 3.3-33.7, p = 0.018).

Conclusion

Malignant wounds severely adversely affect patients' quality of life. However, patients experienced improved quality of life after being treated at a dedicated wound clinic.

Deodorant pad for ulcerated breast cancer: safety and efficacy

OBJECTIVES

APOLLO study, 'efficacy and safety of the deodorAnt Pad against Odour and uLceration for LOcally advanced breast cancer', aimed to assess the safety and efficacy of wearing a deodorant pad in patients with locally advanced breast cancer (LABC) with an ulceration.

METHODS

Komagome Pads were previously developed by Juntendo University and Kao Corporation. In test A, a conventional pad consisting of gauze, a commercially available diaper, pad, etc and the Komagome Pad were compared over 3 days to assess their efficacy and possible improvements for short-term use. In test B, the Komagome Pad was used continuously for 1 month to evaluate its safety during long-term use.

RESULTS

This study included 14 patients in test A and nine in test B. In odour evaluation using sensory testing in test A, nine patients reported more significant efficacy in odour suppression with the Komagome Pad. The odour intensity of the Komagome Pad was lower on the gas chromatography-mass spectrometry. The group with a high level of exudation reported significantly higher satisfaction with the Komagome Pad. In test B, no adverse events were observed.

CONCLUSIONS

A new deodorant pad for LABC demonstrated high safety and deodorant efficacy.

"Maintain Professionalism": Nurses' Experiences in Caring for Patients with Malignant Fungating Wounds in Taiwan

CONTEXT

Malignant fungating wounds (MFWs) occur among 5%-15% of patients with terminal cancers, the uncontrollable symptoms result in serious psychosocial issues, thereby reducing the quality of life. Caring for MFWs impacts caregivers, including healthcare personnel. While existing studies are patient-focused, the impact of care experiences and associated support for nurses has not been examined.

OBJECTIVES

To explore the experiences in caring for patients with MFWs among nurses in Taiwan.

METHODS

Qualitative study with a phenomenological approach by thematic analysis was conducted with semi-structured interviews. About 15 nurses who cared for patients with MFWs at local district hospitals in Southern Taiwan.

RESULTS

Four themes were identified to describe the phenomenon: (1) Fear of Unpredictability (2) Maintaining Professionalism (3) Feeling Helpless (4) Rationalizing the Negatives. The themes illustrated the distress of managing physical symptoms and highlighted how nurses strived to promote comfort for patients. Nurses felt helpless about the incurable nature of MFWs but found a way to suppress their feelings.

CONCLUSION

The findings suggested the need for addressing the emotional well-being of nurses who take care of patients with MFWs. Future studies should identify effective coping strategies for nurses' health when caring for this population.

Caring for Patients With Malignant Fungating Wounds: A Scoping Literature Review

PURPOSE

The aim of this scoping literature review was to identify current knowledge related to management of malignant fungating wounds (MFWs), gaps in this knowledge, and areas for future research.

METHODS

This was a scoping literature review.

SEARCH STRATEGY

Six electronic databases (Embase, MEDLINE, Cochrane (CENTRAL), CINAHL, Scopus, and Web of Science) were searched spanning the years 1987 and 2022. The initial electronic database search retrieved 6041 studies. The search is based on 60 articles published between 1987 and 2022, along with 14 additional studies were based on search of reference lists of key articles.

FINDINGS

Studies were divided into 2 main domains; the vast majority (65 of 72, 87.8%) focused on symptom impact, measurement, and management. The remaining articles (n = 9, 12.2%) focused on caring for patients with MFW; these studies focused on nursing care experiences and competencies, along with lay caregiver experiences. Findings indicated that instruments have been developed to evaluate symptoms of MFW but only a few have been validated. Most of the studies reviewed evaluated the influence of MFW on physical and psychosocial function. Local and systematic symptom managements such as modern dressings, wound care strategies, surgery, and radiotherapy as well as chemotherapy were found to be effective in alleviating symptoms. Findings also indicated that families and nurses encounter obstacles and burdens when caring for patients with MFW; limited studies were retrieved that investigated the competence and needs of nurses in their caring journey.

IMPLICATIONS

Future studies should focus on: (1) using better designs to evaluate and compare topical agents and dressings to control odor, (2) validating assessment tools specific to MFW, (3) qualitative studies designed to enhance understanding family and nurses' experiences, and (4) improving the nurse's ability to care for patients with MFWs and their responses to managing these challenging patients.

Impact of Co-occurring Cancer-Related and Wound-Specific Symptoms on Functional Performance Among Patients With Advanced Cancer and Malignant Fungating Wounds: An Exploratory, Observational Study

PURPOSE

The purpose of this study was to examine the impact of co-occurring symptoms in patients with advanced cancer and malignant fungating wounds (MFWs) on palliative and functional performance, and the feasibility of collecting self-reported data in this population.

DESIGN

This was an exploratory, observational study. Quantitative surveys and qualitative semistructured interviews using a phenomenological approach were employed.

SUBJECTS AND SETTING

The sample comprised 5 adults with advanced breast, oral, and ovarian cancer and MFWs. Participants were recruited from an urban outpatient cancer center, hospice, and wound center located in the Northeastern United States.

METHODS

Demographic and clinical characteristics were collected, and self-reported symptom and functional performance data measured. Descriptive statistics, T scores, confidence intervals, and standard deviation were calculated for quantitative data. One-to-one semistructured interviews were conducted by the first author to gain deeper understanding of participants' symptom experience. Qualitative data were analyzed using an iterative and inductive thematic data analysis method to identify major themes.

RESULTS

The mean cancer-related and wound-specific symptom occurrence was 17 (SD = 5.56) and 4 (SD = 1.26), respectively. Distressing, extensive co-occurring symptom burdens were experienced by all participants; they also reported poor functional performance and diminished palliative performance. Qualitative findings supported quantitative results.

CONCLUSIONS

Findings suggest that co-occurring cancer-related and wound-specific symptoms have incremental and negative impact on functional performance. The use of multiple data collection methods was feasible, including self-reported data in this advanced cancer population.

Fungating and Ulcerating Breast Cancer: Wound Closure Algorithm, Complications, and Survival Trends

Fungating breast cancer severely affects patients' daily lives, and patient management poses major oncology challenges. To present 10-year outcomes of unique tumor presentation, suggesting a focused algorithm for surgical management and providing deep analysis for factors affecting survival and surgical outcomes. Eighty-two patients with fungating breast cancer were enrolled in the period from January 2010 to February 2020 in the Mansoura University Oncology Center database. Epidemiological and pathological characteristics, risk factors, different surgical treatment techniques, and surgical and oncological outcomes were reviewed. Preoperative systemic therapy was used in 41 patients, with the majority (77.8%) showing progressive response. Mastectomy was performed in 81 (98.8%) patients, with primary wound closure in 71 (86.6%), and wide local excision in a single patient (1.2%). Different reconstructive techniques in non-primary closure operations were used. Complications were reported in 33 (40.7%) patients, of which 16 (48.5%) were of Clavien-Dindo grade II category. Loco-regional recurrence occurred in 20.7% of patients. The mortality rate during follow-up was 31.7% (n = 26). Estimated mean overall survival (with 95% CI) was 55.96 (41.98-69.9) months; estimated mean loco-regional recurrence-free survival (with 95% CI) was 38.01 (24.6-51.4) months. Surgery is a cornerstone fungating breast cancer treatment option, but at the expense of high morbidity. Sophisticated reconstructive procedures may be indicated for wound closure. A suggested algorithm based on the center's experience of wound management in difficult mastectomy cases is displayed.

Management of malignant cutaneous wounds in oncologic patients

PURPOSE

Neoplastic wounds may develop as a result of primary tumor growth in the skin, due to metastasis, or due to skin invasion by tumors emerging from deeper levels. Malignant wounds may present as a crater-like ulcer, or as raised nodules with a cauliflower-like appearance. They are associated with malodor, necrosis, pain, bleeding, and secondary infection. The aim of our study is to better characterize fungating wounds and their management.

METHODS

We retrospectively reviewed the database of the Wound Care Unit of the University of Bologna in order to identify individuals affected by neoplastic wound, between January 2019 and February 2021.

RESULTS

We identified 9 females and 2 males with a mean age of 63 years; all were referred by the Oncology Unit. Management differed depending on the characteristics of the patients and the ulcers. Complete healing of the wound, following the parallel complete remission of the lymphoproliferative neoplasia, was observed in one individual. Among the others, one died because of breast cancer, while cutaneous lesions in 2 individuals deteriorated after 1 year of follow-up. Remission/relapse of the ulcer following the treatment course administered for the lymphoma were observed in one patient.

CONCLUSIONS

Treatment of malignant fungating wounds is challenging. Considering the neoplastic nature of the wounds, complete healing or improvement cannot be expected with the application of classically prescribed dressing for wounds. A mostly palliative treatment, focusing on maintaining the patient's quality of life, is a reasonable choice.

[Guideline-based Care for patients with malignant lesions : The new S3 guideline for patients with incurable cancer]

The German Association of Palliative Care developed an evidence-based guideline about the management of malignant wounds in adult patients with incurable cancer. There is a lack of evidence-based guidelines about fungating wounds and a confusing wide range of available wound dressings. The goal of the guideline is to reduce the suffering of patients with malignant wounds and stabilize or improve their quality of life. The guideline is constructed following the German Instrument for Methodological Guideline Appraisal (DELBI): A systematic review was carried out for guidelines and reviews. A wound expert group discussed these research findings and suggested recommendations which were adapted and consented by representatives of 62 medical and health professionals associations.The guideline has 34 recommendations, thereof nine (26%) are evidence based with an evidence level from 2+ to 4 (according to SIGN). The assessment chapter comprises specific assessment tools for malignant wounds, odor and wound-related quality of life. Three recommendations address the psychosocial support of patients and their family caregivers and aim to reduce the impact of the wound on their emotional wellbeing, caregiver burden and social participation. The pain recommendations focus on a preventive atraumatic dressing change, positioning, systemic pain medication (anticipated, rescue and baseline) and local application of morphine or local anesthetics. The guideline gives recommendations on odor management (metronidazole, active coal and antiseptic dressings) and management of exudate (super absorber). The recommendations on prevention and management of bleeding (antifibrinolytica, haemostyptica) are vital for patients and caregivers. This guideline is one of the first evidence-based and consented guideline on malignant wound care and has the potential to improve the palliation of patients who suffer from there malignant wounds.

Reverse Abdominoplasty: A Novel Practical Approach Using Oncoplastic Reconstruction in Managing Major Chest Wall Defects for Patients With Loco-Regional Recurrence Following Breast Cancer Surgery

Background

Loco-regional recurrence of breast cancer in patients with large chest wall defects following mastectomy poses significant oncoplastic challenges. Reverse abdominoplasty is most commonly used to treat patients with excess upper abdominal soft tissue and laxity following massive weight loss. Widely employed as a technique for aesthetic contouring of the upper anterior trunk, as well as in augmentation mammoplasty, its use to date for reconstructive purposes is mainly limited to burns and large site surgical tumour ablation.

Method

Here we review our experience of using reverse abdominoplasty as a novel approach to filling major anterior chest wall defects in patients with cutaneous manifestations of loco-regional or distant recurrence of breast cancer.

Results

Seven patients with metastatic breast cancer underwent reverse abdominoplasty for disease recurrence following mastectomy, with good patient-reported outcomes, and minimal surgical complications. Moreover, follow-up data in the patients surveyed also showed minimal to no limitations on their activities of daily living following the procedure.

Conclusion

Here we demonstrate the successful employment of reverse abdominoplasty - a technique not usually reserved in breast oncoplastic surgery - to treat fungating breast lesions and/or other manifestations of loco-regional recurrence in metastatic breast cancer. This may herald a paradigm shift in the way surgeons approach breast cancer recurrence in patients with pre-existing major chest wall defects.

Myiasis in Neglected Cutaneous Squamous Cell Carcinoma of the Head and Neck: Review of Management and Current Protocol Recommendations

OBJECTIVE

To propose a first-aid management protocol for myiasis in neglected cutaneous squamous cell carcinoma (SCC) in the ED based on a recent literature review.

DATA SOURCES

PubMed.

STUDY SELECTION

Inclusion criteria were all series and case reports of primary/secondary cutaneous SCC with myiasis of the head and neck, including orbital SCC cases, published after 2005.

DATA EXTRACTION

A total of 14 articles including 15 patients were included.

DATA SYNTHESIS

Demographics, socioeconomic situation, site of the lesion, larvae species with bacterial suprainfection, and first-aid treatment options were discussed. Two representative cases are described.

CONCLUSIONS

Large, ulcerated, necrotic, myiasis-burdened SCC lesions in the head and neck area present a challenge for treatment, and to date, no consensus regarding first-aid management exists. The authors' proposed four-pillar first-aid management scheme may be a valid option to rapidly improve wound condition through disinfection, pain relief, and malodor and discharge eradication as a bridge to surgery.

The Microbiome, Malignant Fungating Wounds, and Palliative Care

Malignant fungating wounds present in 5–14% of advanced cancer patients in the United States and are a result of cancerous cells infiltrating and proliferating in the skin. Presentation of malignant fungating wounds often occurs in the last 6 months of life and therefore become symbols of impending death for patients and their families. Due to the incurable and severe nature of these wounds, patients require palliative care until death to minimize pain and suffering. Symptoms associated with these chronic wounds include malodor, pain, bleeding, necrosis, large amounts of exudate, increased microbial growth, and more. Limited research using culture-based techniques has been conducted on malignant fungating wounds and therefore no optimal approach to treating these wounds has been established. Despite limited data, associations between the cutaneous microbiome of these wounds and severity of symptoms have been made. The presence of at least one strain of obligate anaerobic bacteria is linked with severe odor and exudate. A concentration of over 10⁵/g bacteria is linked with increased pain and exudate. Bacterial metabolites such as DMTS and putrescine are linked with components of malignant fungating wound odor and degradation of periwound skin. The few but significant associations made between the malignant fungating wound microbiome and severity of symptoms indicate that further study on this topic using 16S rRNA gene sequencing may reveal potential therapeutic targets within the microbiome to significantly improve current methods of treatment used in the palliative care approach.

Palliative care: needs of advanced breast cancer patients

Advanced breast cancer is characterized by many physical manifestations with the potential to undermine the quality of life (most related to the cancer and some to treatments), as well as substantial impact on psychosocial well-being. Patients with advanced breast cancer and their families have complex needs that have to be addressed in order to minimize severe distress and deterioration in the quality of life of patients and their family members. This task requires the full engagement of an interdisciplinary approach to palliative care with strong emphasis on the assessment of needs and anticipated needs, patient expectations, skilled therapeutics, and commitment to continuity of care. In this review, we address four issues: 1) organizational and conceptual issues in palliative care of patients with breast cancer, 2) common physical symptoms among patients with breast cancer and their management, 3) common psychological issues among patients with breast cancer, and 4) common challenging palliative care problems in breast cancer.

Patients' perceptions and experiences of living with a surgical wound healing by secondary intention: A qualitative study

BACKGROUND

Most surgical wounds heal by primary intention, that is to say, the edges of the wound are brought together with sutures, staples, adhesive glue or clips. However, some wounds may be left open to heal (if there is a risk of infection, or if there has been significant tissue loss), and are known as 'surgical wounds healing by secondary intention'. They are estimated to comprise approximately 28% of all surgical wounds and are frequently complex to manage. However, they are under researched and little is known of their impact on patients' lives.

OBJECTIVES

To explore patients' views and experiences of living with a surgical wound healing by secondary intention.

DESIGN

A qualitative, descriptive approach.

SETTINGS

Participants were recruited from acute and community nursing services in two locations in the North of England characterised by high levels of deprivation and diverse populations.

PARTICIPANTS

Participants were aged 18 years or older and had at least one surgical wound healing by secondary intention, which was slow to heal. Purposeful sampling was used to include patients of different gender, age, wound duration and type of surgery (general, vascular and orthopaedic). Twenty people were interviewed between January and July 2012.

METHODS

Semi-structured interviews were conducted, guided by use of a topic guide developed with input from patient advisors. Data were thematically analysed using steps integral to the 'Framework' approach to analysis, including familiarisation with data; development of a coding scheme; coding, charting and cross comparison of data; interpretation of identified themes.

FINDINGS

Alarm, shock and disbelief were frequently expressed initial reactions, particularly to "unexpected" surgical wounds healing by secondary intention. Wound associated factors almost universally had a profound negative impact on daily life, physical and psychosocial functioning, and wellbeing. Feelings of frustration, powerlessness and guilt were common and debilitating. Patients' hopes for healing were often unrealistic, posing challenges for the clinicians caring for them. Participants expressed dissatisfaction with a perceived lack of continuity and consistency of care in relation to wound management.

CONCLUSIONS

Surgical wounds healing by secondary intention can have a devastating effect on patients, both physical and psychosocial. Repercussions for patients' family members can also be extremely detrimental, including financial pressures. Health care professionals involved in the care of patients with these wounds face multiple, complex challenges, compounded by the limited evidence base regarding cost-effectiveness of different treatment regimens for these types of wounds.

Topical agents and dressings for fungating wounds

BACKGROUND

Fungating wounds arise from primary, secondary or recurrent malignant disease and are associated with advanced cancer. A small proportion of patients may achieve healing following surgical excision, but treatment is usually palliative. Fungating wound management usually aims to slow disease progression and optimise quality of life by alleviating physical symptoms, such as copious exudate, malodour, pain and the risk of haemorrhage, through selection of appropriate dressings and topical agents.

OBJECTIVES

To review the evidence of the effects of dressings and topical agents on quality of life, and symptoms that impact on quality of life, in people with fungating malignant wounds.

SEARCH METHODS

For this third update we searched the Wounds Group Specialised Register in August 2013; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL.

SELECTION CRITERIA

Eligible studies comprised randomised controlled trials (RCTs) or, in their absence, controlled clinical trials (CCTs) with a concurrent control group.

DATA COLLECTION AND ANALYSIS

Data extraction and risk of bias assessment was undertaken by one review author and checked for accuracy by a second.

MAIN RESULTS

Four trials involving 164 people were included. One RCT in women with superficial breast lesions compared 6% miltefosine solution with placebo and found that miltefosine delayed tumour progression. The study reported that the time to treatment failure was significantly longer in the miltefosine group (median 56 days) than in the placebo group (median 21 days) (p value 0.007, log-rank test). A second trial compared topical metronidazole with placebo but the results up to the point of cross-over were not statistically significant. A third trial compared the effect of foam dressings containing silver to foam dressings without silver and found that more patients experienced decreased malodour in the foam with silver group than in the foam alone group (p value=0.049). The fourth trial compared the effect of manuka honey-coated dressings with nanocrystalline silver-coated dressings and found no statistically significant difference with regard to exudate, malodour and wound pain. All trials, however, had methodological limitations.

AUTHORS' CONCLUSIONS

There is weak evidence from one small trial that 6% miltefosine solution applied topically to people with superficial fungating breast lesions (smaller than 1cm) who have received either previous radiotherapy, surgery, hormonal therapy or chemotherapy for their breast cancer, may slow disease progression. There is also weak evidence to suggest that foam dressings containing silver may be effective in reducing malodour. There is insufficient evidence in this review to give a clear direction for practice with regard to improving quality of life or managing wound symptoms associated with fungating wounds. More research is needed.

Superabsorbent dressings for copiously exuding wounds

Exudate control is important in the management of both acute and chronic wounds. A new category of absorbent dressings that contain superabsorbent particles promises high absorbency. The aim of this multicentre, prospective, non-comparative observational study was to evaluate the clinical efficacy and absorbent capacity of a superabsorbent dressing. Fifteen inpatients and outpatients with highly exuding wounds were included. Most patients (n=8) (53%) had chronic wounds; 20% (n=3) had ulcerating tumours. The superabsorbent dressing was used as a primary or a secondary dressing. Assessment was on day 0 (start), day 3 and day 7 (end of study). The study looked at wound bed and periwound skin condition, exudate production, pain upon dressing removal, reason for dressing removal, and frequency of dressing changes. A clinical visual scoring tool was used, together with digital photographs, which were assessed by the same experienced clinician. All 15 patients completed the study, during which no adverse events were noted. At day 7, maceration had reduced from 46.7% (n=7) at day 0 to 6.7% (n=1). After only 3 days, dressing change frequency was reduced from once daily to twice weekly in 80% (n=12) of patients. The superabsorbent dressing seems to reduce complications associated with exudate production, stimulate wound healing and increase patient comfort; it may also save time and costs for caregivers.

Symptom burden and quality of life in patients with malignant fungating wounds

AIM

This study describes the relationship between symptoms and quality of life in patients with malignant fungating wounds.

BACKGROUND

Malignant fungating wounds are complex wounds that can bleed, become malodorous due to infection and are painful causing physical and psychological distress. However, there is a lack of literature on the impact that such wounds can have on quality of life.

METHODS

This was a descriptive, cross-sectional multi-centre study of patients with malignant fungating wounds. Participants were recruited from the palliative care, hospice, outpatient clinic and oncology units of three medical centres in Taiwan. Data were collected from February 2008 to August 2009. A structured questionnaire obtained socio-demographic information, medical details, wound assessment information and the Taiwanese version of the McGill quality of life questionnaire was administered by interview.

RESULTS

  McGill quality of life scores indicated that the participants had the lowest quality of life. The participant's age, dressing change frequency, pain, wound dressing comfort, wound symptom, bleeding and malodour had statistically significant negative correlations with quality of life. Multiple regression analysis showed that age, malodour, pain issues and psychological issues explained 87% of the total variance in quality of life.

CONCLUSION

  This study contributes to our understanding of the impact of malignant fungating wounds and how correct assessment and management is necessary to improve quality of life. Educational intervention research is needed for patients and caregivers in countries where this has not yet been performed. Further research should also identify whether nursing competence has a direct impact on quality of life.

The effect of honey-coated bandages compared with silver-coated bandages on treatment of malignant wounds-a randomized study

Malignant wounds (MWs) occur in 5-10% of all cancer patients. Malodor and exudation are the most common side effects. The aim was to determine the influence of honey-coated compared with silver-coated bandages on treatment of MWs. Patients were randomly selected to enter either group A (honey-coated bandages) or group B (silver-coated bandages). Parameters were the following: wound size, cleanliness, malodor, exudation, and wound pain. Digital photographs, visual analog scales (VAS), and wound morphology registration were used for measurement at baseline and following the 4-week intervention. Sixty-nine patients with MWs and advanced cancer, aged 47-90 (median 65.6), were included. No statistically significant difference was noted between the groups with respect to wound size, degree of cleanliness, exudation, malodor, and wound pain. There was a median decrease in wound size of 15 cm² and 8 cm² in group A and B, respectively (p = 0.63). Based on post-intervention pooled data from the groups, improvement was seen in 62% of the participants with respect to wound size and in 58% (n = 69) with respect to cleanliness. The VAS score for malodor (p = 0.007) and exudation (p < 0.0001) improved significantly post-intervention. Patients with reduced wound size had a median survival time of 387 days compared with 134 days in patients with no wound reduction (p = 0.003). The use of honey-coated and silver-coated bandages improved the outcome of MWs. No differences were found between the two regimens. Both types of bandages are recommended for use by patients with MWs containing tumor debris and necrosis.

An intense and unforgettable experience: the lived experience of malignant wounds from the perspectives of patients, caregivers and nurses

Malignant wounds occur infrequently, but are typically described as devastating and overwhelming. However, there has been little formalised research, and the vast majority of existing malignant wound literature comprises reports of health care professionals from their management of the physical symptoms. Few studies have investigated the lived experience from the perspectives of patients and nurses and none have investigated the experiences of lay caregivers caring for a patient with a malignant wound. As a result, there has been little mention in existing literature of the non physical issues associated with malignant wounds or how they might be addressed. The purpose of this study was to address this gap in knowledge by investigating the lived experience of malignant wounds from the perspectives of those living it. In-depth interviews were conducted with patients, caregivers and nurses. The data were analysed thematically within a hermeneutic phenomenological methodology to show four themes: (i) malodour; (ii) new mode of being-in-the-world; (iii) still room for hope and (iv) enduring memories. Although this study confirmed previous findings that malodour was one of the worst aspects of malignant wounds, it was significant that the other three themes occurred in the previously largely overlooked psychosocial domain.
