Prevalence, exposure and the public knowledge of keloids on four continents.

INTRODUCTION: Keloid scars are associated with physical and psychological sequelae. No studies have investigated the general public's understanding of keloids. Targeted, short educational interventions in susceptible individuals may aid understanding of the condition and compliance with treatment. We aimed to identify the population with the highest prevalence and lowest knowledge. METHODS: We surveyed four countries to determine the public's understanding of keloids. A quantitative, subjective and cross-sectional street survey was designed using the knowledge, attitudes and practice model principles. The target populations were cities in Ghana, Australia, Canada and England. Surveyors used a hybrid stratified/convenience sampling method. Primary outcomes were prevalence, exposure to keloids as an entity and overall keloid knowledge score compared across demographic groups. Study data have been made fully available for reproducibility and education (https://doi.org/10.17605/OSF.IO/3KZ5E). RESULTS: There were 402 respondents, with a median age of 32 (interquartile range 25-45.25) years, of which 193 were females. The survey was carried out between June 2015 and October 2017. The prevalence of self-identified keloids was 11% in Ghana, 6% in Australia, 2% in Canada and 7% in England. Prevalence, exposure and knowledge were higher in the Ghanaian population. CONCLUSIONS: There was association between knowledge, prevalence and the exposure to keloids as an entity. Findings may suggest targeting public health campaigns towards populations where knowledge is lowest, and exposure to and prevalence of keloids are the highest.

Meta-analysis on the comparative efficacy of drains, progressive tension sutures and subscarpal fat preservation in reducing complications of abdominoplasty.

INTRODUCTION: Abdominoplasty is a popular aesthetic operation. Complication rates vary from 4-80%. To date, there is a lack of evidence for complication-reducing techniques. The aim of this meta-analysis was to summarise and quantify the effects of these techniques on complication rates and determine the safest combination. METHODS: A literature search was undertaken from MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases. Two authors assessed the abstracts and evaluated their suitability for inclusion in the review. For each complication (including overall), a random effects meta-analysis was conducted to investigate the average number of complications. The log rate and associated variance is calculated in R using the "escalc" function from the metafor R package. For the forest plots the model output is back-transformed to the original scale. RESULTS: 4295 patients were included in the meta-analysis. Overall complication rates ranged from 9.3-33.8%. Revision rates were 3-21.9%. Forest plots of data extracted from observational studies demonstrated summary measures favouring the sub-scarpal fat preservation and drains, and drains only groups for overall complications. There were no significant differences between groups for seroma, haematoma, infection/abscess, skin/fat necrosis, dehiscence, surgical revision rate and VTE rate. CONCLUSIONS: The rates of individual complications are no different with or without the use of PTS, drain or sub-Scarpal fat preservation in different combinations.

Low-Dose Insulin as an Antiscarring Therapy in Breast Surgery: A Randomized Controlled Trial.

BACKGROUND: The role of insulin in expediting wound healing is firmly established within the context of major trauma and burns; however, only limited clinical evidence exists as to its effects on scar formation. This study aims to build on previous laboratory work to examine the potential antiscarring properties of insulin in a clinical environment. METHODS: Ninety-one patients undergoing bilateral aesthetic breast operations were recruited to receive low-dose insulin and placebo injections to the medial 3 cm of their submammary incisions within the context of a randomized, intrapatient, placebo-controlled trial, and scar quality was assessed at 3-, 6-, and 12-month reviews using the Manchester Scar Scale. RESULTS: Across the cohort at 12-month review, the insulin-treated scars had lower scar scores (p = 0.055) compared with placebo. Subgroup analysis of individuals with heavier scars showed that median scar scores were significantly lower for the insulin-treated scars with regard to both scar contour (p = 0.048) and scar distortion (p = 0.045). CONCLUSIONS: Subcutaneous insulin injections reduced the appearance of scarring in this study compared with placebo. The greatest effect was seen in those participants who showed heavier scars and, as such, insulin has a role as an antiscarring therapy in individuals likely to be affected by heavier scarring. Further research is required to more precisely delineate which subjects may benefit most from this treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

The provision of emotional labour by health care assistants caring for dying cancer patients in the community: a qualitative study into the experiences of health care assistants and bereaved family carers.

BACKGROUND: While previous research has suggested that health care assistants supporting palliative care work in the community regard the provision of emotional labour as a key aspect of their role, little research has explored the experiences of family carers who are the recipients of such support. OBJECTIVE: To explore the emotional labour undertaken by health care assistants working in community palliative care from the perspectives of both health care assistants and bereaved family carers. DESIGN: We conducted a qualitative interview study in 2011-2012 with bereaved family carers of cancer patients who had received the services of health care assistants in the community, and health care assistants who provided community palliative care services. Transcripts were coded and analysed for emergent themes using a constant comparative technique. SETTINGS: Three different research sites in the United Kingdom, all providing community palliative care. PARTICIPANTS AND METHODS: Semi-structured interviews were conducted with 33 bereaved family carers and eight health care assistants. RESULTS: Health care assistants view one of their key roles as providing emotional support to patients and their family carers, and family carers recognise and value this emotional support. Emotional support by health care assistants was demonstrated in three main ways: the relationships which health care assistants developed and maintained on the professional-personal boundary; the ability of health care assistants to negotiate clinical/domestic boundaries in the home; the ways in which health care assistants and family carers worked together to enable the patient to die at home. CONCLUSION: Through their emotional labour, health care assistants perform an important role in community palliative care which is greatly valued by family carers. While recent reports have highlighted potential dangers in the ambiguity of their role, any attempts to clarify the 'boundaries' of the health care assistant role should acknowledge the advantages health care assistants can bring in bridging potential gaps between healthcare professionals and family carers.
