Wound Bed Preparation 2024: Delphi Consensus on Foot Ulcer Management in Resource-Limited Settings.

GENERAL PURPOSE: To review a practical and scientifically sound application of the wound bed preparation model for communities without ideal resources. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Summarize issues related to wound assessment.2. Identify a class of drugs for the treatment of type II diabetes mellitus that has been shown to improve glycemia, nephroprotection, and cardiovascular outcomes.3. Synthesize strategies for wound management, including treatment in resource-limited settings.4. Specify the target time for edge advancement in chronic, healable wounds.

Chronic wound management in low-resource settings deserves special attention. Rural or underresourced settings (ie, those with limited basic needs/healthcare supplies and inconsistent availability of interprofessional team members) may not have the capacity to apply or duplicate best practices from urban or abundantly-resourced settings. The authors linked world expertise to develop a practical and scientifically sound application of the wound bed preparation model for communities without ideal resources. A group of 41 wound experts from 15 countries reached a consensus on wound bed preparation in resource-limited settings. Each statement of 10 key concepts (32 substatements) reached more than 88% consensus. The consensus statements and rationales can guide clinical practice and research for practitioners in low-resource settings. These concepts should prompt ongoing innovation to improve patient outcomes and healthcare system efficiency for all persons with foot ulcers, especially persons with diabetes.

Wound Bed Preparation 2021.

GENERAL PURPOSE: To present the 2021 update of the Wound Bed Preparation paradigm. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will: 1. Apply wound assessment strategies. 2. Identify patient concerns about wound care. 3. Select management options for healable, nonhealable, and maintenance wounds.

Wound Bed Preparation is a paradigm to optimize chronic wound treatment. This holistic approach examines the treatment of the cause and patient-centered concerns to determine if a wound is healable, a maintenance wound, or nonhealable (palliative). For healable wounds (with adequate blood supply and a cause that can be corrected), moisture balance is indicated along with active debridement and control of local infection or abnormal inflammation. In maintenance and nonhealable wounds, the emphasis changes to patient comfort, relieving pain, controlling odor, preventing infection by decreasing bacteria on the wound surface, conservative debridement of slough, and moisture management including exudate control. In this fourth revision, the authors have reformulated the model into 10 statements. This article will focus on the literature in the last 5 years or new interpretations of older literature. This process is designed to facilitate knowledge translation in the clinical setting and improve patient outcomes at a lower cost to the healthcare system.

A systematic review of the validity and reliability of apathy scales in neurodegenerative conditions.

BACKGROUND: There are several scales used to detect apathy in disease populations. Since apathy is a prevalent symptom in many neurodegenerative diseases, this is an especially important context in which to identify and compare scales. AIMS: To provide an overview of apathy scales validated in generic and specific neurodegenerative disease populations, compare validation studies' methodological quality and the psychometric properties of the validated apathy scales. METHODS: A systematic review of literature was conducted of articles published between 1980 and 2013. The final articles selected for review were rated on methodological quality and the psychometric properties of the scales used were interpreted. RESULTS: Sixteen articles validating apathy scales were included in the review, five in a generic neurodegenerative sample and eleven in specific neurodegenerative samples. The methodological quality of specific studies varied from poor to excellent. The highest quality, which had psychometrically favorable scales, were the dementia apathy interview and rating (DAIR) and the apathy evaluation scale-clinical version (AES-C) in Alzheimer's disease and the Lille apathy rating scale (LARS) in Parkinson's disease. Generic neurodegenerative disease validation studies were of average methodological quality and yielded inconsistent psychometric properties. CONCLUSIONS: Several instruments can be recommended for use in some specific neurodegenerative diseases. Other instruments should either be validated or developed to assess apathy in more generic populations.

The long-term outcomes of transcoronary ablation of septal hypertrophy compared to surgical myectomy in patients with symptomatic hypertrophic obstructive cardiomyopathy.

OBJECTIVES: The aim of this study was to compare the long-term outcomes of transcoronary ablation of septal hypertrophy (TASH) with open surgical myomectomy (SM) in patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM). METHODS: We reviewed patients who underwent either procedure at our institution. The demographics, clinical outcomes, echocardiographic parameters, and complications were compared. RESULTS: Seventy patients with HOCM were treated with either TASH (n = 47, 26 male) or SM (n = 23, 10 male). Compared to those treated with SM, patients undergoing TASH were older (57+/- 14.7 years versus 47 +/- 20.6 years, P = 0.021) and more symptomatic. A higher proportion of patients had syncope as a presenting feature in the TASH group compared to the SM group (57.5% vs. 17.4%, P = 0.002) respectively. They were also more likely to be in New York Heart Association (NYHA) class III/IV compared to the patients who underwent SM (85.1% vs. 39.1%; P < 0.001). Patients were followed for a mean period of 43 months (TASH) and 46 months (SM). Repeat procedures were more common in the TASH group (17% vs. 0%, P = 0.04) but mitral valve replacement was more common in the SM group (0% vs. 8.7%, P = 0.105). Symptom improvement, the rate of complications and all cause mortality rates were similar in both groups. CONCLUSIONS: TASH compares favorably with surgical myectomy with regard to symptom resolution, rate of complications and mortality in a tertiary referral centre and should be seen as an attractive alternative to surgical myectomy in the appropriate patient population.

The relationship between preoperative frailty and outcomes following transcatheter aortic valve implantation: a systematic review and meta-analysis.

Aims: Transcatheter aortic valve implantation (TAVI) is an increasingly common intervention for patients with aortic stenosis deemed high risk for major cardiac surgery, but identifying those who will benefit can be challenging. Frailty reflects physiological reserve and may be a useful prognostic marker in this population. We performed a systematic review and meta-analysis of the association between frailty and outcomes after TAVI. Methods and Results: Five databases were searched between January 2000 and May 2015. From 2623 articles screened, 54 were assessed for eligibility. Ten cohort studies (n = 4592) met the inclusion criteria of reporting a measure of frailty with early (≤30 days) or late (>30 days) mortality and procedural complications following TAVI as defined by the Valve Academic Research Consortium (VARC). Frailty was associated with increased early mortality in four studies (n = 1900) (HR 2.35, 95% CI 1.78-3.09, P < 0.001) and increased late mortality in seven studies (n = 3159) (HR 1.63, 95% CI 1.34-1.97, P < 0.001). Objective frailty tools identified an even higher risk group for late mortality (HR 2.63, 95% CI 1.87-3.70, P < 0.001). Frail individuals undergoing TAVI have a mortality rate of 34 deaths per 100 patient years, compared with 19 deaths per 100 patient years in non-frail patients. There was limited reporting of VARC procedural outcomes in relation to frailty, preventing meta-analysis. Conclusion: Frailty assessment in an already vulnerable TAVI population identifies individuals at even greater risk of poor outcomes. Use of objective frailty tools may inform patient selection, but this requires further assessment in large prospective registries.

Atorvastatin as a stable treatment in bronchiectasis: a randomised controlled trial.

BACKGROUND: Bronchiectasis is characterised by chronic cough, sputum production, and recurrent chest infections. Pathogenesis is poorly understood, but excess neutrophilic airway inflammation is seen. Accumulating evidence suggests that statins have pleiotropic effects; therefore, these drugs could be a potential anti-inflammatory treatment for patients with bronchiectasis. We did a proof-of-concept randomised controlled trial to establish if atorvastatin could reduce cough in patients with bronchiectasis. METHODS: Patients aged 18-79 years were recruited from a secondary-care clinic in Edinburgh, UK. Participants had clinically significant bronchiectasis (ie, cough and sputum production when clinically stable) confirmed by chest CT and two or more chest infections in the preceding year. Individuals were randomly allocated to receive either high-dose atorvastatin (80 mg) or a placebo, given orally once a day for 6 months. Sequence generation was done with a block randomisation of four. Random allocation was masked to study investigators and patients. The primary endpoint was reduction in cough from baseline to 6 months, measured by the Leicester Cough Questionnaire (LCQ) score, with a lower score indicating a more severe cough (minimum clinically important difference, 1·3 units). Analysis was done by intention-to-treat. The trial is registered with ClinicalTrials.gov, number NCT01299181. FINDINGS: Between June 23, 2011, and Jan 30, 2011, 82 patients were screened for inclusion in the study and 22 were excluded before randomisation. 30 individuals were assigned atorvastatin and 30 were allocated placebo. The change from baseline to 6 months in LCQ score differed between groups, with a mean change of 1·5 units in patients allocated atorvastatin versus -0·7 units in those assigned placebo (mean difference 2·2, 95% CI 0·5-3·9; p=0·01). 12 (40%) of 30 patients in the atorvastatin group improved by 1·3 units or more on the LCQ compared with five (17%) of 30 in the placebo group (difference 23%, 95% CI 1-45; p=0·04). Ten (33%) patients assigned atorvastatin had an adverse event versus three (10%) allocated placebo (difference 23%, 95% CI 3-43; p=0·02). No serious adverse events were recorded. INTERPRETATION: 6 months of atorvastatin improved cough on a quality-of-life scale in patients with bronchiectasis. Multicentre studies are now needed to assess whether long-term statin treatment can reduce exacerbations. FUNDING: Chief Scientist's Office.
