    Families discuss food and eating in many ways that may shape child eating habits. Researchers studying how families talk about food have examined this process during meals. Little work has examined parent-child food-related interactions outside of mealtime. We assessed family food talk at home outside of mealtime and tested whether food talk was associated with obesogenic child eating behaviors, maternal feeding practices, or child weight. Preschool and school-aged mother-child dyads (n = 61) participated in naturalistic voice recording using a LENA (Language ENvironment Analysis) recorder. A coding scheme was developed to reliably characterize different types of food talk from LENA transcripts. Mothers completed the Children's Eating Behavior Questionnaire (CEBQ) and Child Feeding Questionnaire (CFQ) to assess child eating behaviors and maternal feeding practices. Child weight and height were measured and body mass index z-score (BMIz) calculated. Bivariate associations among food talk types, as a proportion of total speech, were examined and multivariate regression models used to test associations between food talk and child eating behaviors, maternal feeding practices, and child BMIz. Proportion of child Overall Food Talk and Food Explanations were positively associated with CEBQ Food Responsiveness and Enjoyment of Food (p's < 0.05). Child food Desire/Need and child Prep/Planning talk were positively associated with CEBQ Enjoyment of Food (p < 0.05). Child Food Enjoyment talk and mother Overt Restriction talk were positively associated with CEBQ Emotional Over-Eating (p < 0.05). Mother Monitoring talk was positively associated with CFQ Restriction (p < 0.05). Mother Prep/Planning talk was negatively associated with child BMIz. Food talk outside of mealtimes related to child obesogenic eating behaviors and feeding practices in expected ways; examining food talk outside of meals is a novel way to consider feeding practices and child eating behavior

    Fat talk, negative communication about weight, is common in the media, peer groups, and families. Little is known about parental fat talk directed at oneself or others. This study examined associations between different forms of parental fat talk and child disordered eating behaviors and weight, and differences by child sex and age. Parents of preadolescents or adolescents (n = 581) reported fat talk about themselves (self-fat talk), others (obesity-fat talk), and their child (child-fat talk). 76.0% of parents reported regular self-fat talk in front of children, 51.5% reported obesity-fat talk, and 43.6% reported child-fat talk. Fat talk did not differ significantly between parents of preadolescents and adolescents but was more common with sons than daughters. Of the three forms of fat talk, only child-fat talk was associated with all child eating and weight variables (binge eating, overeating, secretive eating, and overweight/obesity); associations were strongest for adolescent girls. Child sex was associated with secretive eating and overweight/obesity. Parents reported using different forms of fat talk frequently. Parent self- and obesity-fat talk were reported more frequently, but child-fat talk was the most strongly associated with children's eating and weight. Because of associations with disordered eating behaviors, intervening to reduce fat talk might contribute to improving pediatric disordered eating and weight-related interventions. © 2018 Wiley Periodicals, Inc.

  3. Why do women engage in fat talk? Examining fat talk using Self-Determination Theory as an explanatory framework.

    This study used Self-Determination Theory to examine the motivational processes involved in individuals' engagement in fat talk and its association with unhealthy eating behaviors. Female undergraduate students (N=453) completed an online questionnaire, which assessed general and contextual motivation, importance placed on goals, fat talk, and unhealthy eating behaviors. Structural equation modeling revealed that being generally non-self-determined and placing more importance on extrinsic goals, such as thinness, was associated with fat talk. Fat talk was further associated with non-self-determined motivation for eating regulation, which in turn was associated with unhealthy eating. General self-determination and placing more importance on intrinsic goals, such as health, were not associated with fat talk, but instead, were associated with more adaptive forms of eating regulation and diet quality. Findings further current knowledge on the respective roles of motivation and goals on the engagement in fat talk, and its consequences on eating regulation and behavior.

  5. In It Together: Mother Talk of Weight Concerns Moderates Negative Outcomes of Encouragement to Lose Weight on Daughter Body Dissatisfaction and Disordered Eating

    Mothers’ influence on their daughters is important for understanding girls’ disordered eating and body dissatisfaction. Direct maternal encouragement of daughters to lose weight is linked to daughters’ development of bulimic symptoms, and additional findings indicate that daughters whose mothers merely talk about dieting and body dissatisfaction are more likely to be diagnosed with an eating disorder. The current study extends such research by examining the interactive contributions of maternal encouragement to lose weight and maternal dieting discussions to the prediction of early adolescent daughters’ body dissatisfaction and disordered eating over the middle school period. Participants were 89 adolescent girls who were in the 6th grade at Time 1. Regression analyses were conducted to examine interactive effects of mother encouragement to diet and talk of weight concerns on daughter body dissatisfaction, drive for thinness, and dieting behavior. Results suggest an interactive effect in which mothers’ dieting talk may act as a buffer against the negative effects of direct encouragement to lose weight. PMID:26551484

    In order to understand how age, culture, and problems in motor coordination impact the performance of activities of daily living, we used focus groups and in-depth interviews with Australian and Canadian parents to examine activities of daily living of younger (5-7 years of age) and older (8-9 years of age) children with and without DCD. By comparison with their typically developing age group, children with DCD had more difficulty with dressing, personal hygiene, and eating skills. Difficulties with postural control and fine-motor skills were reported to contribute to poorer performance of activities of daily living. As expected, competence in the performance of activities of daily living improved in the older children with and without DCD and there were few differences in the performance of daily living tasks between typical children in Australia and Canada. Overall, the motor difficulties of children with DCD had a significant impact on performance of a wide range of daily activities.

    Disordered eating behavior-dieting, laxative use, fasting, binge eating-is common in college-aged women (11%-20%). A documented increase in the number of young women experiencing eating psychopathology has been blamed on the rise of engagement with social media sites such as Facebook. We predicted that college-aged women's Facebook intensity (e.g., the amount of time spent on Facebook, number of Facebook friends, and integration of Facebook into daily life), online physical appearance comparison (i.e., comparing one's appearance to others' on social media), and online "fat talk" (i.e., talking negatively about one's body) would be positively associated with their disordered eating behavior. In an online survey, 128 college-aged women (81.3% Caucasian, 6.7% Asian, 9.0% African-American, and 3.0% Other) completed items, which measured their disordered eating, Facebook intensity, online physical appearance comparison, online fat talk, body mass index, depression, anxiety, perfectionism, impulsivity, and self-efficacy. In regression analyses, Facebook intensity, online physical appearance comparison, and online fat talk were significantly and uniquely associated with disordered eating and explained a large percentage of the variance in disordered eating (60%) in conjunction with covariates. However, greater Facebook intensity was associated with decreased disordered eating behavior, whereas both online physical appearance comparison and online fat talk were associated with greater disordered eating. College-aged women who endorsed greater Facebook intensity were less likely to struggle with disordered eating when online physical appearance comparison was accounted for statistically. Facebook intensity may carry both risks and benefits for disordered eating. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Though parental modeling is thought to play a critical role in promoting children's healthy eating, little research has examined maternal food intake and maternal food talk as independent predictors of children's food intake. The present study examines maternal food talk during a structured eating protocol, in which mothers and their children had the opportunity to eat a series of familiar and unfamiliar vegetables and desserts. Several aspects of maternal talk during the protocol were coded, including overall food talk, directives, pronoun use, and questions. This study analyzed the predictors of maternal food talk and whether maternal food talk and maternal food intake predicted children's food intake during the protocol. Higher maternal body mass index (BMI) predicted lower amounts of food talk, pronoun use, and questions. Higher child BMI z-scores predicted more first person pronouns and more wh-questions within maternal food talk. Mothers of older children used fewer directives, fewer second person pronouns, and fewer yes/no questions. However, maternal food talk (overall and specific types of food talk) did not predict children's food intake. Instead, the most robust predictor of children's food intake during this protocol was the amount of food that mothers ate while sitting with their children. These findings emphasize the importance of modeling healthy eating through action and have implications for designing interventions to provide parents with more effective tools to promote their children's healthy eating.

    2014-09-01

    Fat talk is a style of verbal expression among young women involving negative self-statements, complaints about physical appearance, and weight management. This research used ecological momentary assessment to examine the impact of naturalistic fat talk experiences on body dissatisfaction, body checking, negative affect, and disordered eating behaviors. We examined trait self-objectification as a moderator. Sixty-five female college students completed a baseline questionnaire and responded to questions when randomly prompted by palm pilot devices for five days. Results indicated fat talk is common and associated with greater body dissatisfaction, body checking, negative affect, and disordered eating behaviors. Fat talk participation was associated with greater body checking than overhearing fat talk. Greater trait self-objectification was associated with greater body dissatisfaction and body checking following fat talk. These results suggest that fat talk negatively impacts the cognitions, affect, and behavior of young women and has increased negative effects for women higher in self-objectification.

    Fat talk is a form of self-degrading, thin-ideal endorsing communication that occurs within female friendship groups. Previous studies have suggested negative associations with wellbeing, but have been predominantly correlational and based on self-report. This study aimed to assess the causal relationship between fat talk and the correlates of disordered eating (thin-ideal internalization, body dissatisfaction, negative affect, and dieting intentions) by experimentally manipulating fat talk in existing friendship groups and measuring naturalistic expression of fat talk and its effects. Participants were 85 women aged 17-25 who completed the experiment in friendship pairs. They were randomly assigned to a condition in which their friend expressed fat talk, positive body talk, or neutral talk. This study found evidence of a causal link between listening to friends fat talk and increased correlates of disordered eating. The negative effects of listening to fat talk were fully mediated by fat talk expression. This study also revealed a social function of fat talk, whereby participants rated their friends more positively when they were perceived to behave consistently with group norms, either pro- or anti-fat talk. Positive body talk showed none of the negative effects of fat talk, and was considered socially acceptable regardless of existing friendship group norms. These findings indicate that fat talk is a mechanism through which the thin ideal is transmitted between individuals. Interventions at the level of the friendship group to challenge norms and communication styles may break the link between societal risk factors and individual risk of eating disorders. © 2015 Wiley Periodicals, Inc.

    Three institutions enrolled 38 patients who required bilateral skin graft donor sites into a safety and efficacy study of a new synthetic donor site dressing. Bilateral donor sites were randomized to receive either a new, synthetic donor site dressing or an impregnated gauze dressing. Wounds were assessed by time to healing, pain, and patient preference. Synthetic dressing wounds were treated 7.9 days compared with 10.2 days for gauze dressing wounds (p < 0.001), and synthetic dressing wounds were more completely epithelialized. Visual analogue pain analysis revealed significantly less donor site pain with synthetic dressing (2.94) versus gauze dressing (4.64) (p < 0.001). Synthetic dressing had fewer treatment-related adverse experiences than gauze dressing (2 vs 7) and was judged by recipients to be superior to gauze dressing in comfort, pain relief, cosmetic appeal, ease of ambulation, and overall acceptance.

  16. Dressing disrupted: negotiating care through the materiality of dress in the context of dementia.

    2018-02-01

    This paper explores how the materiality of dress mediates and shapes practices of care in the context of dementia. Earlier research called for an approach to conceptualising care that recognised the role played by everyday artefacts. We extend this to a consideration of dress and dressing the body in relation to people with dementia that involves the direct manipulation of material objects, as well as the materiality of bodies. The paper draws on an ESRC funded study Dementia and Dress, which examined experiences of dress for people with dementia, families and care-workers using ethnographic and qualitative methods. Our analysis explores the process of dressing the body, the physicality of guiding and manipulating bodies into clothing, dealing with fabrics and bodies which 'act back' and are resistant to the process of dressing. We consider how the materiality of clothing can constrain or enable practices of care, exploring tensions between garments that support ease of dressing and those that sustain identity. Examining negotiations around dress also reveals tensions between competing 'logics' of care (Mol ). © 2018 The Authors.

    2003-07-01

    Painful split-skin-graft donor sites remain a common problem for patients. We undertook a prospective randomised trial to examine the comparative comfort and ease of care of two different donor-site dressings. One dressing is the alginate Kaltostat, the standard plastic-surgical dressing in the UK and abroad, and the other is the adhesive retention tape Mefix, a novel use of a readily available dressing. We randomised 50 patients requiring split-skin grafts to receive either alginate (Kaltostat) or retention (Mefix) donor-site dressings. Dressings were assessed by interview and questionnaire at 24, 72 h and 2 weeks, and by wound review at 2 weeks. Retention dressings were found to be more comfortable, required less nursing intervention and allowed patients easier mobility with a greater range of daily activities, especially washing, without compromising wound healing. We recommend adhesive retention dressings as cost-effective comfortable dressings, which readily conform to any donor site.

    The purpose of this study was to describe outcomes and resource utilization in patients treated with twice-weekly silver impregnated (SI) nanocrystalline dressings for initial non-operative management of giant omphalocele (GO). A retrospective review of patients with GO treated with SI dressings was undertaken. Clinical parameters, cost, and complications were recorded. Five patients with GO were treated with SI dressings between 2014 and 2016. Clinical characteristic (mean ± SD) included gestational age 36 ± 4 weeks, birth weight 2.6 ± 0.63 kg, GO size 10.2 ± 4.7 cm, ventilator days 7.5 ± 8.7 d, days in NICU 41 ± 20 d, days to full feeds, 30 ± 15 d, and LOS 62 ± 41 d. The average in-hospital cost of SI dressings was $110 CAD/week. This is comparable to daily silver sulfadiazine dressings ($109CAD/week) which were used historically. All patients were discharged with once- or twice-weekly dressing changes. No ruptures occurred. There was one mortality secondary to pulmonary sepsis. For initial non-operative management of GO, twice weekly SI nanocrystalline dressings is safe and effective. Use of SI dressings results in decreased handling of infants, reduced physician and nursing resource utilization, and favourable outcomes. IV (Retrospective Case Series). Copyright © 2018.

    The purpose of this study was to compare the efficacy of dressings containing octenidine vs. dressings containing silver in the wound healing in the course of a chronic venous disease. There were two groups of 40 patients who met the inclusion criteria and who did not meet the exclusion criteria. The patients were randomly assigned into the groups (envelope method). The first, "O group" was treated with octenidine-based dressings. The second, "S group" was treated with silver dressings. The study lasted for 56 days. All patients in the research were treated with medical compression stockings with cotton understockings. Microbiological eradication was observed on the 28th day of the study among 33% of patients in the treatment group vs. 6% in control group. On the 56th day of the treatment, these percentages equalled 72% and 35%. The rate of healing was faster in the 0 group than in the S group. In the wounds <10 cm(2) it was faster by 1.35 cm(2)/week and in wounds >10 cm(2) it equalled 3.44 cm(2). The reduction of pain level was 37.5% higher in the O group, in contrast with the S group. One change of a dressing in the O group led to a 0.06 cm(2) greater wound size reduction and in the case of wounds >10 cm(2) to 0.29 cm(2) reduction compared with the S group. The presented results indicate that the efficacy of dressings containing octenidine is higher compared to silver dressings. © 2015 by the Wound Healing Society.

    Although "fat talk" is associated with increased eating disorder risk, the predictors of fat talk engagement and viable alternatives to these pervasive conversations remain unclear. The current experiment examined responses to fat talk versus feminist-oriented challenging fat talk scenarios. Undergraduate women (N=283) completed baseline questionnaires assessing body dissatisfaction, fat talk engagement, and positive impression management. One week later, they were randomized to view one of the two scenarios, followed by assessment of mood, fat talk engagement, social acceptability, and social likeability. Results indicated that the challenging fat talk vignette (versus the fat talk vignette) yielded less negative affect and fat talk and was perceived as more socially attractive with a more likeable target character. Baseline body dissatisfaction, baseline fat talk tendencies, and momentary negative affect predicted post-exposure fat talk engagement. Current findings highlight possibilities for implementing feminist language and psychoeducation in fat talk prevention efforts. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Objective The prevalence of weight-related problems in adolescents is high. Parents of adolescents may wonder whether talking about eating habits and weight is useful or detrimental. This study aimed to examine the associations between parent conversations about healthful eating and weight and adolescent disordered eating behaviors. Design Cross-sectional analysis using data from two linked multi-level population-based studies. Setting Anthropometric assessments and surveys completed at school by adolescents and surveys completed at home by parents in 2009–2010. Participants Socio-economically and racially/ethnically diverse sample (81% ethnic minority; 60% low income) of adolescents from EAT (Eating and Activity in Teens) 2010 (n = 2,793, mean age=14.4) and parents from F-EAT (Families and Eating and Activity in Teens) (n = 3,709, mean age = 42.3). Main Exposure Parent conversations about healthful eating and weight/size. Outcome Measures Adolescent dieting, unhealthy weight control behaviors, and binge eating. Results Mothers and fathers who engaged in weight-related conversations had adolescents who were more likely to diet, use unhealthy weight control behaviors, and engage in binge eating. Overweight/obese adolescents whose mothers engaged in conversations that were focused only on healthful eating behaviors were less likely to diet and use unhealthy weight control behaviors. Additionally, sub-analyses with adolescents with data from two parents showed that when both parents engaged in healthful eating conversations, their overweight/obese adolescent children were less likely to diet and use unhealthy weight control behaviors. Conclusion Parent conversations focused on weight/size are associated with increased risk for adolescent disordered eating behaviors, whereas conversations focused on healthful eating are protective against disordered eating behaviors.

    In the process of chronic wound care, adhesive wound dressings may cause pain and injury in the wound environment during dressing changes. At present, no standardized test procedures are available for the investigation of adhesion of wound dressings. Therefore, our study aimed to test the adhesion of different wound dressings on steel as well as on healthy skin. Within an open, comparative study, the adhesive areas of 56 wound dressings were investigated. The adhesives were categorized into acrylate (n = 23), silicone (n = 9), hydrocolloid (n = 17) and polyurethane groups (n = 7). Using an especially modified testing machine, the adhesion of the wound dressings was measured on steel as well as on the skin of healthy study participants, in compliance with the European EN 1939:2003 standard. The energy required to remove the wound dressings from human skin, was measured in Newton (N) and the following median values were obtained: hydrocolloid (2.25 N) > acrylate (1.14 N) > polyurethane (0.9 N) > silicone (0.7 N). The subjective pain intensity during the removal of the wound dressings was recorded using the visual analogue scale (VAS) with values ranging from 0 to 10. For hydrocolloid, it was 6.8, for acrylate 4.9, for polyurethane 3.1 and for silicone 2.5 points VAS. In comparison with human skin, the adhesion of wound dressings was significantly higher on steel (P < 0.0001), but was different for the different groups of wound dressings. Moreover, there was a statistically significant correlation between the adhesion and pain intensity (correlation coefficient 0.806; P = 0.01). The knowledge about the widely differing adhesion properties of different wound dressings on the skin of patients should nowadays be considered during the individual selection of the applied products. Based on these data, different types of wound dressings could be developed, guaranteeing a good adhesion and a low traumatic risk when removed. © 2010 The Authors. Journal of the European

    To evaluate the safety, efficacy, and patient acceptance of closed dressings after full facial resurfacing with the carbon dioxide laser. Prospective cohort of men and women undergoing full facial carbon dioxide laser resurfacing. Ambulatory surgical center at a university hospital. Forty consecutive patients randomized to 1 of 4 dressing groups. All patients underwent full facial resurfacing with a carbon dioxide laser system. One of 5 closed dressings (single- or 3-layer composite foam, plastic mesh, hydrogel, or polymer film) was placed immediately after the procedure. Closed dressings were changed on postoperative day 2 and removed on postoperative day 4. Objective postoperative criteria of erythema, scarring, reepithelialization, and surface irregularities were recorded and photodocumented. Comparisons were made among the closed dressing groups as well as with a group of historical control subjects treated with open dressings. The ease of application, office time for preparation and application, and cost of the individual dressings were collected. Patient characteristics of overall acceptance, comfort, and ease of maintenance were recorded with a visual analog scale. There were no complications of scarring, surface irregularities, or contact dermatitis from the application or maintenance of the closed dressings. There were no significant differences in the number of days of postoperative erythema or in the rate of facial reepithelialization among the groups. Most patients preferred not to continue with the closed dressings past 2 days. Positive features from the use of closed dressings included reduction in crust formation, decreased pruritus, decreased erythema, and decreased postoperative pain, compared with historical controls. Negative features included time in preparation and application of the dressings. Costs ranged from $9.79 to $50 per dressing change. Closed dressings are safe and offer benefits noted during the first 4 postoperative days. Patients

    During the last 25 years, the careful examination of the eating behavior of individuals with eating disorders has provided critical insights into the nature of these disorders. Crucially, studies investigating components of different eating behaviors have documented that Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED) are characterized by objective disturbances in eating patterns that are significantly different than behaviors exhibited by individuals who do not have these eating disorders. The detailed description of the disturbances in eating behavior has helped to identify diagnostic criteria associated with each disorder, and has led to important hypotheses about the underlying pathophysiology. These advances in understanding have provided, and continue to provide, a foundation for translational research and for the development of novel treatment interventions. This review is based on a presentation given by B. Timothy Walsh, M.D. at the 40th anniversary symposium of the Columbia University Appetite talks outlining the evolution of the discovery of the characteristic eating disturbances seen with each disorder.

  11. Dress Nicer = Know More? Young Children’s Knowledge Attribution and Selective Learning Based on How Others Dress

    PubMed Central

    McDonald, Kyla P.; Ma, Lili

    2015-01-01

    This research explored whether children judge the knowledge state of others and selectively learn novel information from them based on how they dress. The results indicated that 4- and 6-year-olds identified a formally dressed individual as more knowledgeable about new things in general than a casually dressed one (Study 1). Moreover, children displayed an overall preference to seek help from a formally dressed individual rather than a casually dressed one when learning about novel objects and animals (Study 2). These findings are discussed in relation to the halo effect, and may have important implications for child educators regarding how instructor dress might influence young students’ knowledge attribution and learning preferences.

    Evidence suggests that adolescents’ experience of binge eating (BE) might differ in important ways from that of adults. Moreover, although BE appears more common in African American women than other disordered eating behaviors, little is known about the influence of cultural factors on this behavior in adolescents. The current investigation used qualitative methodology to examine the perceptions of White and African American adolescent girls and their mothers regarding experiences of binge and loss of control eating. Five focus groups were completed with 19 adolescent girls (aged 13–17, 58 % African American, 41 % White) who endorsed loss of control eating behaviors. Their mothers (N = 19) also completed separate, concurrent focus groups addressing food and eating behaviors. Responses to focus group questions were analyzed using thematic qualitative analysis. Adolescents’ awareness of their eating behaviors varied greatly. Girls reported some awareness of how emotions influence their eating behaviors, and described using food to achieve autonomy. Mothers evidenced awareness of their daughters’ problematic eating behaviors, the effects of emotions on eating for both their daughters and themselves, and sociocultural factors influencing diet. Data from these focus groups can inform the development of innovative interventions for adolescent girls engaging in loss of control eating. PMID:25400491

  13. Tiny patients, tiny dressings: a guide to the neonatal PICC dressing change.

    Sharpe, Elizabeth L

    2008-06-01

    Advances in neonatology now support the survival of the tiniest of infants. The peripherally inserted central catheter (PICC) has now become an integral part of routine practice in neonatal intensive care units around the world. Keen attention to safe maintenance of these devices is essential. A properly applied and maintained PICC dressing is the first line of defense to minimize the risk of complications such as dislodgement, migration, and infection. This article describes a neonatal PICC dressing change and discusses the frequently encountered quandaries surrounding this important procedure, including dressing materials, frequency, site preparation, barrier precautions, and other relevant concerns.

    Background Prior research has critiqued the lack of attention to the stressors associated with dementia related dressing issues, stigmatizing patient clothing, and wearable technology challenges. This paper describes the conceptual development and feasibility testing of an innovative ‘smart dresser’ context aware affective system (DRESS) to enable dressing by people with moderate memory loss through individualized audio and visual task prompting in real time. Methods Mixed method feasibility study involving qualitative focus groups with 25 Alzheimer’s family caregivers experiencing dressing difficulties to iteratively inform system design and a quantitative usability trial with 10 healthy subjects in a controlled laboratory setting to assess validity of technical operations. Results Caregivers voiced the need for tangible dressing assistance to reduce their frustration from time spent in repetitive cueing and power struggles over dressing. They contributed 6 changes that influenced the prototype development, most notably adding a dresser top iPad to mimic a familiar ‘TV screen’ for the audio and visual cueing. DRESS demonstrated promising overall functionality, however the validity of identification of dressing status ranged from 0% for the correct pants dressing to 100% for all shirts dressing scenarios. Adjustments were made to the detection components of the system raising the accuracy of detection of all acted dressing scenarios for pants from 50% to 82%. Conclusions Findings demonstrate family caregiver acceptability of the proposed system, the successful interoperability of the built system’s components, and the system’s ability to interpret correct and incorrect dressing actions in controlled laboratory simulations. Future research will advance the system to the alpha stage and subsequent testing with end users in real world settings. PMID:26321895

    It is important to reduce potential wound complications in total hip and total knee arthroplasty procedures. The purpose of this study was to compare the jubilee dressing method to a standard adhesive dressing. 124 patients (62 total hip replacements and 62 total knee replacements) were randomly selected to have either a standard adhesive dressing or jubilee method dressing. The number of dressing changes, incidence of blistering, leakage, appearance of inflammation, infection rate and the average stay in hospital was recorded for each patient. The jubilee dressing significantly reduced the rate of blistering, leakage and number of dressing changes when compare to a traditional adhesive dressing (p < 0.05). The rate of inflammation and average length of stay in hospital was not significantly different between the two groups. The authors recommend the use of this dressing for total hip and total knee arthroplasty procedures due to the associated lower complication rate. Copyright © 2012 Tissue Viability Society.

    Pressure ulcers, also known as pressure injuries and bed sores, are localised areas of injury to the skin or underlying tissues, or both. Dressings made from a variety of materials, including foam, are used to treat pressure ulcers. An evidence-based overview of dressings for pressure ulcers is needed to enable informed decision-making on dressing use. This review is part of a suite of Cochrane Reviews investigating the use of dressings in the treatment of pressure ulcers. Each review will focus on a particular dressing type. To assess the clinical and cost effectiveness of foam wound dressings for healing pressure ulcers in people with an existing pressure ulcer in any care setting. In February 2017 we searched: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase; EBSCO CINAHL Plus and the NHS Economic Evaluation Database (NHS EED). We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) and cluster-RCTs, that compared the clinical and cost effectiveness of foam wound dressings for healing pressure ulcers (Category/Stage II or above). Two review authors independently performed study selection, risk of bias and data extraction. A third reviewer resolved discrepancies between the review authors. We included nine trials with a total of 483 participants, all of whom were adults (59 years or older) with an existing pressure ulcer Category/Stage II or above. All trials had two arms, which compared foam dressings with other dressings for treating pressure ulcers.The certainty of evidence ranged from low to very low due

    Most vascular catheter-related infections (CRIs) occur extraluminally in patients in the intensive care unit (ICU). Chlorhexidine-impregnated and strongly adherent dressings may decrease catheter colonization and CRI rates. To determine if chlorhexidine-impregnated and strongly adherent dressings decrease catheter colonization and CRI rates. In a 2:1:1 assessor-masked randomized trial in patients with vascular catheters inserted for an expected duration of 48 hours or more in 12 French ICUs, we compared chlorhexidine dressings, highly adhesive dressings, and standard dressings from May 2010 to July 2011. Coprimary endpoints were major CRI with or without catheter-related bloodstream infection (CR-BSI) with chlorhexidine versus nonchlorhexidine dressings and catheter colonization rate with highly adhesive nonchlorhexidine versus standard nonchlorhexidine dressings. Catheter-colonization, CR-BSIs, and skin reactions were secondary endpoints. A total of 1,879 patients (4,163 catheters and 34,339 catheter-days) were evaluated. With chlorhexidine dressings, the major-CRI rate was 67% lower (0.7 per 1,000 vs. 2.1 per 1,000 catheter-days; hazard ratio [HR], 0.328; 95% confidence interval [CI], 0.174-0.619; P = 0.0006) and the CR-BSI rate 60% lower (0.5 per 1,000 vs. 1.3 per 1,000 catheter-days; HR, 0.402; 95% CI, 0.186-0.868; P = 0.02) than with nonchlorhexidine dressings; decreases were noted in catheter colonization and skin colonization rates at catheter removal. The contact dermatitis rate was 1.1% with and 0.29% without chlorhexidine. Highly adhesive dressings decreased the detachment rate to 64.3% versus 71.9% (P < 0.0001) and the number of dressings per catheter to two (one to four) versus three (one to five) (P < 0.0001) but increased skin colonization (P < 0.0001) and catheter colonization (HR, 1.650; 95% CI, 1.21-2.26; P = 0.0016) without influencing CRI or CR-BSI rates. A large randomized trial demonstrated that chlorhexidine-gel-impregnated dressings decreased

    2009-01-01

    This article explores the ways that participants in a Chinese cancer support group talk about food, diet, and eating. An ethnographic research design was used, including participant observation at a Chinese cancer support group over an 8-month period and key informant interviews with 7 members of the group. Food, eating, and diet were a recurrent focus of discussion at support group meetings throughout the fieldwork period. The ways in which support group participants talked about food centered on 3 distinct but interconnected themes: the prevalence of eating issues as an adverse effect of cancer and its treatment, the importance of eating ability, and questions and concerns connected with the differing and often contradictory cultural models of diet that they were exposed to. Culturally specific understandings of the relationship between food and health informed Chinese patients' experience of eating issues during cancer treatments and their ongoing concern with food and nutrition after the completion of treatment. Health professionals need to pay more attention to the meanings and attributes of food and eating beyond their physiological properties, and further research needs to be conducted with other immigrant populations with culturally distinct understandings of food.

    Our new collagen dressing has been developed recently. Three types (A, B, and C) of the dressing were prepared in this study. Each type contained bacitracin, neomycin or colistin. The antibiotic was input into: i. collagen sponge (CS)--type A, ii. layer of limited hydrophobicity (LLH)--type B, and iii. into both CS and LLH layers--type C. The final concentration of the antibiotic that resulted from the loading level was 2 mg/cm2 for the dressings of type A and B and 4 mg/cm2 for the dressing of type C. The antibiotics were then extracted from the pieces of dressings for two days through dialysis membrane. Susceptibility of 54 bacterial strains (S. aureus, P. aeruginosa, and Acinetobacter) isolated from burn wounds were tested to the three antibiotics used for preparation of the dressings. The results of the study evidenced that efficiency of released of antibiotics into the extracts depended on the kind of antibiotic and on the type of dressing. The concentration of the antibiotics proved to be much higher than MIC90 values of the bacterial isolates tested in respect to their susceptibility. The dressing containing mixture of the three antibiotics in two layers--CS and LLH is now considered as potentially effective for care of infected wounds. It may be useful for the treatment of infected wounds or for profilaxis of contaminated wounds, ensuring: i. sufficient antimicrobial activity in wound, and ii. optimal wound environment for the presence of collagenic biomaterial on the damaged tissue.

  7. Choosing a Wound Dressing Based on Common Wound Characteristics

    PubMed Central

    Dabiri, Ganary; Damstetter, Elizabeth; Phillips, Tania

    2016-01-01

    Significance: Chronic wounds are a major healthcare burden.The practitioner should have an appropriate understanding of both the etiology of the wound as well as the optimal type of dressings to use. Fundamental wound characteristics may be used to guide the practitioner's choice of dressings. The identification of optimal dressings to use for a particular wound type is an important element in facilitating wound healing. Recent Advances: Researchers have sought to design wound dressings that aim to optimize each stage in the healing process. In addition, dressings have been designed to target and kill infection-causing bacteria, with the incorporation of antimicrobial agents. Critical Issues: Chronic wounds are frequently dynamic in presentation, and the numerous wound dressings available make dressing selection challenging for the practitioner. Choosing the correct dressing decreases time to healing, provides cost-effective care, and improves patient quality of life. Future Directions: Research into the mechanisms of wound healing has enhanced our ability to heal chronic wounds at a faster rate through the use of moisture-retentive dressings. Newer dressings are incorporating the use of nanotechnology by incorporating miniature electrical sensors into the dressing. These dressings are engineered to detect changes in a wound environment and alert the patient or practitioner by altering the color of the dressing or sending a message to a smartphone. Additional investigations are underway that incorporate biologic material such as stem cells into dressings. PMID:26858913

  9. Effects of adhesive dressings on stratum corneum conductance.

    PubMed

    Cavallini, Maurizio; Gazzola, Riccardo; Vaienti, Luca

    2012-05-01

    Stratum corneum is a fundamental layer of epidermis. It acts as a barrier, with antimicrobial features, regulating skin permeability and integrity as well. Adhesive dressings and their removal could alter this layer, affecting cutaneous water balance and lipid composition of stratum corneum. These changes could be monitored by measurement of cutaneous hydration. Ninety-two patients affected by wounds dressed with adhesive tapes or plasters have been studied. Measurement of skin conductance under tape/plaster and in the surrounding healthy skin, immediately after removal of dressing has been performed. Dressing age, wound localization, and characteristics were also considered. Adhesive dressings alter significantly stratum corneum conductance. Although healthy skin hydration has significant variations throughout the body, cutaneous conductance under adhesive dressing in different areas displays no significative changes. Moreover, the increase in hydration due to adhesive tapes/plasters showed no association with wound dehiscence. Adhesive dressings cause a significative increase in stratum corneum conductance, acting as a barrier to apocrine secretions. Although different hydration levels have been observed in healthy skin throughout the body, no difference exists under adhesive dressing among different regions, suggesting no contraindications in their employment throughout the body. Increase in cutaneous hydration showed no correlations with wound dehiscence, thus confirming safety and practicality of these dressings. © 2011 John Wiley & Sons A/S.

    To evaluate and compare the costs of using a transparent polyurethane film (PF) and hydrocolloid dressing (HD) in the prevention of pressure ulcers (PUs). This descriptive, observational, longitudinal, comparative study was conducted in the intensive care units, coronary care unit and medical clinic of a charity hospital in Brazil. Data were collected during a 30-day study period, consisting of physical examination, assessment of risk factors for PU development and application of the Braden scale, which were performed at inclusion in the study and once daily during hospitalisation. Either PF or HD was applied bilaterally in the sacral and trochanteric regions for prevention of PUs in patients at a moderate to high risk of PUs according to the Braden scale, and costs of using PU preventive dressings were estimated. The mean total costs per dressing change per patient when using the HD and PF to prevent PUs were 413.60 BRL and 74.04 BRL, respectively. There were significant between-group differences in mean costs for all variables, except for saline solution and nurse-technician services. Results showed that the mean cost per dressing change per patient was lower when using the transparent PF than when using the HD.

    There is an ever increasing array of products available for wound dressings. The aim of the present study was to establish which dressings should be used as standard controls for future studies; what factors are regarded as most important in assessing a dressing; what the level of satisfaction is with the available products; what the strengths and weaknesses of the commonly used dressings are; and what dressings would be preferred if cost were no issue. A postal survey was sent to every plastic and reconstructive surgeon registered in Australasia (n = 217). A total of 53% responded. The most commonly used dressing type overall is the calcium alginates, despite the fact that they were not the highest performing dressings. This is also the most commonly used in Australia. In contrast scarlet red is still used most commonly in New Zealand. The level of satisfaction with the most commonly used dressing varied very little. The factor regarded most important was patient comfort level. A profile of the commonly used dressing was constructed. Calcium alginates and or scarlet red should be used as the control for new product comparisons. Most of the respondents were satisfied with their preferred dressing and were not interested in trying alternative dressings.

    In recent years, a number of food poisoning outbreaks due to the contamination of norovirus in ready-to-eat (RTE) foods such as salads have been reported, and this issue is regarded as a global problem. The risk of contamination of fresh vegetables with norovirus has been previously reported, but the survivability of norovirus that contaminates salads remains unknown. In addition, there have been limited reports on the control of norovirus in food products by using inactivating agents. In this study, the viability of norovirus in various types of salads and dressings was examined using murine norovirus strain 1 (MNV-1) as a surrogate for the closely related human norovirus. In addition, the inactivation of MNV-1 in salads was examined using heat-denatured lysozyme, which had been reported to inactivate norovirus. MNV-1 was inoculated in 4 types of salads (coleslaw, thousand island salad, vinaigrette salad, egg salad) and 3 types of dressings (mayonnaise, thousand island dressing, vinaigrette dressing), stored at 4°C for 5days. The results revealed that in the vinaigrette dressing, the infectivity of MNV-1 decreased by 2.6logPFU/mL in 5days, whereas in the other dressings and salads, the infectivity of MNV-1 did not show any significant decrease. Next, 1% heat-denatured lysozyme was added to the 4 types of salads, and subsequently it was found that in 2 types of salads (thousand island salad, vinaigrette salad), the infectivity of MNV-1 decreased by >4.0logPFU/g, whereas in coleslaw salad, a decrease of 3.0logPFU/g was shown. However, in egg salads, the infectivity of MNV-1 did not show such decrease. These results suggest that norovirus can survive for 5days in contaminated salads. Further, these findings also indicated that heat-denatured lysozyme had an inactivating effect on norovirus, even in salads. In the future, heat-denatured lysozyme can be used as a novel norovirus-inactivating agent, although it is essential to investigate the mechanism of inactivating

    2010-01-01

    Based on her anthropological research, Nichter (2000) concluded that it is normative for many American girls to engage in body self-disparagement in the form of "fat talk." The purpose of the present two studies was to develop a quantitative measure of fat talk. A series of 17 scenarios were created in which "Naomi" is talking with a female friend(s) and there is an expression of fat talk. College women respondents rated the frequency with which they would behave in a similar way as the women in each scenario. A nine-item one-factor scale was determined through principal components analysis and its scores yielded evidence of internal consistency reliability, test-retest reliability over a five-week time period, construct validity, discriminant validity, and incremental validity in that it predicted unique variance in body shame and eating disorder symptoms above and beyond other measures of self-objectification.

    To improve arterial catheter (AC) securement and reduce AC failure; to assess feasibility of a large randomised controlled trial. A four-arm, parallel, randomised, controlled, non-blinded pilot trial with 195 intensive care patients taking part, in a tertiary referral hospital in Brisbane, Australia from May to November 2012. Standard polyurethane (SPU) dressing (controls); bordered polyurethane (BPU) + SPU dressing; tissue adhesive (TA) + SPU dressing; and sutureless securement device (SSD) + SPU dressing (no sutures used). AC failure, ie, complete dislodgement, occlusion (monitor failure, inability to infuse or fluid leaking), pain or infection (local or blood). Median AC dwell time was 26.2 hours and was comparable between groups. AC failure occurred in 26/195 patients (13%). AC failure was significantly worse with SPU dressings (10/47 [21%]) than with BPU + SPU dressings (2/ 43 [5%]; P = 0.03), but not significantly different to TA + SPU (6/56 [11%]; P = 0.18) or SSD + SPU (8/49 [16%]; P = 0.61). The dressing applied at AC insertion lasted until AC removal in 68% of controls; 56% of BPU + SPU dressings; 73% of TA + SPU dressings; and 80% of SSD + SPU dressings (all P > 0.05). There were no infections or serious adverse events. Patient and staff satisfaction with all products was high. Median costs (labour and materials) for securement per patient were significantly higher in all groups compared with the control group (SPU, $3.48 [IQR, $3.48-$9.79]; BPU + SPU, $5.07 [IQR, $5.07-$12.99]; SSD + SPU, $10.90 [IQR, $10.90-$10.90]; TA + SPU, $17.70 [IQR, $17.70-$38.36]; all P < 0.01). AC failure occurred significantly less often with BPU + SPU dressings than with SPU dressings. TA + SPU and SSD + SPU dressings should be further investigated and compared with BPU + SPU dressings as controls. The novel approach of TA + SPU dressings appeared safe and feasible.

The cost of each intervention was based on the unit amount used in each type of dressing, and its purchase price (transparent film = R$15.80, hydrocolloid dressing = R$68.00). the mean cost/patient was R$23.17 for use of transparent film and R$190.40 for use of hydrocolloid dressing. The main reason for changing the dressing was detachment. the transparent film was the most economically advantageous alternative to prevent sacral pressure ulcers in critical care patients. However, additional studies should be carried out including assessment of the effectiveness of both dressings.

    To evaluate how pain, during and in-between dressing changes, is affected by the introduction of Mepilex Border Lite, a wound dressing manufactured by Mölnlycke Health Care using Safetac soft silicone adhesive technology, to the treatment of different types of paediatric wounds/skin injuries. Wounds/skin injuries that met the criteria for inclusion in the study were dressed with Mepilex Border Lite. Patients were followed for six weeks or until their wounds/skin injuries had healed, whichever occurred earlier. At each dressing change, pain severity before and during dressing removal was rated by the patient and the investigator on a scale from zero (no pain at all) to ten (worst pain ever). Other variables measured included: signs of trauma to wound/skin injury and surrounding skin, the proportion of viable/non-viable tissue, the quantity and appearance of exudate, odour, and clinical signs of infection. At the final dressing change, patients and investigators completed questionnaires to rate the dressing performance. Mean pain severity scores were significantly lower (p < or = 0.003) at the first dressing change than at baseline. Over 99.5 per cent of the Mepilex Border Lite dressing changes were reported to be atraumatic and more than half of the wounds healed within the study period. Conformability, ease of use, ease of removal, patient comfort, and overall experience with the dressing were rated as 'good' to 'very good' at the vast majority of final visit evaluations. This study provides further evidence of the ability of dressings with Safetac soft silicone adhesive technology to minimise trauma and pain and demonstrates the ability of Mepilex Border Lite to overcome the clinical challenges associated with the use of dressings on the wounds/skin injuries of paediatric patients.

    A fast and effective wound healing process would substantially decrease medical costs, wound care supplies, and hospitalization significantly improving the patients’ quality of life. The search for effective therapeutic approaches seems to be imperative in order to avoid the aggravation of chronic wounds. In spite of all the efforts that have been made during the recent years towards the development of artificial wound dressings, none of the currently available options combine all the requirements necessary for quick and optimal cutaneous regeneration. Therefore, technological advances in the area of temporary and permanent smart dressings for wound care are required. The development of nanoscience and nanotechnology can improve the materials and designs used in topical wound care in order to efficiently release antimicrobial, anti-inflammatory and regenerative compounds speeding up the endogenous healing process. Nanostructured dressings can overcome the limitations of the current coverings and, separately, natural origin components can also overcome the drawbacks of current antibiotics and antiseptics (mainly cytotoxicity, antibiotic resistance, and allergies). The combination of natural origin components with demonstrated antibiotic, regenerative, or anti-inflammatory properties together with nanostructured materials is a promising approach to fulfil all the requirements needed for the next generation of bioactive wound dressings. Microbially compromised wounds have been treated with different essential oils, honey, cationic peptides, aloe vera, plant extracts, and other natural origin occurring antimicrobial, anti-inflammatory, and regenerative components but the available evidence is limited and insufficient to be able to draw reliable conclusions and to extrapolate those findings to the clinical practice. The evidence and some promising preliminary results indicate that future comparative studies are justified but instead of talking about the beneficial or

    Post cardiac catheterization puncture site care is usually done with a tight pressure dressing by an elastic adhesive bandage (Tensoplast) due to the belief that it should prevent bleeding. The practice is uncomfortable to the patients. The authors compared a new way of dressing using light transparent tape (Tegaderm) to the conventional tight pressure one. 126 post coronary angiography patients were randomized to have their groins dressed either with Tensoplast or with Tegaderm. Patients ambulated 8 hours after the procedures. The groin was evaluated for pain, discomfort and bleeding complications. 49 per cent in the Tensoplast vs 26.9 per cent in the Tegaderm group experienced pain (p value of 0.01). 55.5 per cent in the Tensoplast group vs 11.1 per cent in the Tegaderm group reported discomfort. 4.7 per cent in the Tensoplast vs 1.6 per cent in the Tegaderm group developed bleeding or hematoma. Dressing of the puncture site after cardiac catheterization with Tegaderm was more comfortable than the conventional Tensoplast without any difference in bleeding complications.

    Optical illusions have broadened our understanding of the brain's role in visual perception. A modern day optical illusion emerged from a posted photo of a striped dress, which some perceived as white and gold and others as blue and black. Here we show, using functional magnetic resonance imaging (fMRI), that those who perceive The Dress as white/gold have higher activation in response to the image of The Dress in brain regions critically involved in higher cognition (frontal and parietal brain areas). These results are consistent with theories of top-down modulation and present a neural signature associated with the differences in perceiving The Dress as white/gold or blue/black. Furthermore the results support recent psychophysiological data on this phenomenon and provide a fundamental building block to study interindividual differences in visual processing.

    Coherent dressing of a quantum two-level system provides access to a new quantum system with improved properties—a different and easily tunable level splitting, faster control and longer coherence times. In our work we investigate the properties of the dressed, donor-bound electron spin in silicon, and assess its potential as a quantum bit in scalable architectures. The two dressed spin-polariton levels constitute a quantum bit that can be coherently driven with an oscillating magnetic field, an oscillating electric field, frequency modulation of the driving field or a simple detuning pulse. We measure coherence times of T* 2p = 2.4 ms andmore » T Hahn 2p = 9 ms, one order of magnitude longer than those of the undressed spin. Moreover, the use of the dressed states enables coherent coupling of the solid-state spins to electric fields and mechanical oscillations.« less

    Recently, biomimetic wound dressings were introduced as potential replacements for treating skin injuries. Although there are some clinically available skin replacements, the range of wound types and locations necessitates a broader range of options for the clinic. Natural polymeric-based dressings are of central interest in this area due to their outstanding biocompatibility, biodegradability, low toxicity, and non-allergenic nature. Among them, silk fibroin (SF) has exceptional characteristics as a wound dressing. SF-based dressings can also be used as carriers for delivering drugs, growth factors, and bioactive agents to the wound area, while providing appropriate support for complete healing. In this review, we describe recent advances in the development of SF-based wound dressings for skin regeneration. Copyright © 2018 Elsevier Ltd. All rights reserved.

    In vitro cytotoxicity studies of periodontal dressings have not generally produced a result consistent with in vivo observations. These prior in vitro studies have not used human intraoral cell lines. We tested the effects of two eugenol containing and two non-eugenol periodontal dressings on cultured human gingival fibroblasts (HGF) (ATCC No. 1292). Replicate HGF cultures grown in microtiter plates were exposed to stock, 1:4 and 1:16 dilutions of extracts made from each of the four periodontal dressings. The HGF cultures were pulse labelled with tritiated thymidine (3HTdR) after 24, 48, and 72 hours. Incorporations of the labelled thymidine were measuredmore » using liquid scintillation counting and expressed as counts per minute. The results showed that undiluted extracts from all four periodontal dressings totally inhibited 3HTdR uptake (P less than 0.05). The 1:4 dilution of eugenol dressings inhibited 3HTdR uptake significantly more than non-eugenol dressings (P less than 0.05). Interestingly, at 72 hours the 1:16 dilution of the non-eugenol dressings caused significantly increased 3HTdR uptake which was not observed with the eugenol dressings. The present results suggest that the use of a human fibroblastic cell line for testing the effects of periodontal dressings may provide information about the relative biological effects of these dressings. Using this cell line, we have found that eugenol dressings inhibit fibroblast proliferation to a greater extent than non-eugenol dressings.« less

    Background: Xeroform remains the current standard for treating superficial partial-thickness burns but can be prohibitively expensive in developing countries with prevalent burn injuries. This study (1) describes the production of an alternative low-cost dressing and (2) compares the alternative dressing and Xeroform using the metrics of cost-effectiveness, antimicrobial activity, and biocompatibility in vitro, and wound healing in vivo. Methods: To produce the alternative dressing, 3% bismuth tribromophenate powder was combined with petroleum jelly by hand and applied to Kerlix gauze. To assess cost-effectiveness, the unit costs of Xeroform and components of the alternative dressing were compared. To assess antimicrobial properties, the dressings were placed on agar plated with Escherichia coli and the Kirby-Bauer assay performed. To assess biocompatibility, the dressings were incubated with human dermal fibroblasts and cells stained with methylene blue. To assess in vivo wound healing, dressings were applied to excisional wounds on rats and the rate of re-epithelialization calculated. Results: The alternative dressing costs 34% of the least expensive brand of Xeroform. Antimicrobial assays showed that both dressings had similar bacteriostatic effects. Biocompatibility assays showed that there was no statistical difference (P < 0.05) in the cytotoxicity of Xeroform, alternative dressing, and Kerlix gauze. Finally, the in vivo healing model showed no statistical difference (P < 0.05) in mean re-epithelialization time between Xeroform (13.0 ± 1.6 days) and alternative dressing (13.5 ± 1.0 days). Conclusions: Xeroform is biocompatible, reduces infection, and enhances healing of burn wounds by preventing desiccation and mechanical trauma. Handmade petrolatum gauze may be a low-cost replacement for Xeroform. Future studies will focus on clinical trials in burn units. PMID:27482485

    Significance: Injury to the skin provides a unique challenge, as wound healing is a complex and intricate process. Acute wounds have the potential to move from the acute wound to chronic wounds, requiring the physician to have a thorough understanding of outside interventions to bring these wounds back into the healing cascade. Recent Advances: The development of new and effective interventions in wound care remains an area of intense research. Negative pressure wound therapy has undoubtedly changed wound care from this point forward and has proven beneficial for a variety of wounds. Hydroconductive dressings are another category that is emerging with studies underway. Other modalities such as hyperbaric oxygen, growth factors, biologic dressings, skin substitutes, and regenerative materials have also proven efficacious in advancing the wound-healing process through a variety of mechanisms. Critical Issues: There is an overwhelming amount of wound dressings available in the market. This implies the lack of full understanding of wound care and management. The point of using advanced dressings is to improve upon specific wound characteristics to bring it as close to “ideal” as possible. It is only after properly assessing the wound characteristics and obtaining knowledge about available products that the “ideal” dressing may be chosen. Future Directions: The future of wound healing at this point remains unknown. Few high-quality, randomized controlled trials evaluating wound dressings exist and do not clearly demonstrate superiority of many materials or categories. Comparative effectiveness research can be used as a tool to evaluate topical therapy for wound care moving into the future. Until further data emerge, education on the available products and logical clinical thought must prevail. PMID:25126472

  10. Situating wound management: technoscience, dressings and 'other' skins.

    PubMed

    Rudge, T

    1999-09-01

    This paper addresses the notion of wound care as a technology of skin and other skins imbued with the combined power of technology and science. It presents the discourses of wound care evident in the accounts of patients and nurses concerning this care, and discussions about wounds in wound care interest groups, journals, and advertising material about wound care products. The discussion focuses on wounds and wound dressings as effects immanent in the power relations of discourses of wound care. These effects colour and influence nurses' responses to wounds and wound care products. Moreover, the discourses that portray these practices are evidence of the complex articulation between technoscience and gender. Nurses and patients are fascinated by wound technoscience and lured towards it by its potential for mastery and control over wounds. Such seductions are evident in the texts of nurses, patients, and pharmaceutical advertisements for wound care products. Finally, the ways that these representations are used to talk about and market wound care products are shown as exemplifying the finer points of wound management as a nursing technoscience.

    Although new therapeutic approaches for burn treatment have made progress, there is still need for better methods to enhance wound healing and recovery especially in severely burned patients. Nanofibrillar cellulose (NFC) has gained attention due to its renewable nature, good biocompatibility and excellent physical properties that are of importance for a range of applications in pharmaceutical and biomedical fields. In the present study, we investigated the potential of a wood based NFC wound dressing in a clinical trial on burn patients. Previously, we have investigated NFC as a topical functionalized wound dressing that contributes to improve wound healing in mice. Wood based NFC wound dressing was tested in split-thickness skin graft donor site treatment for nine burn patients in clinical trials at Helsinki Burn Centre. NFC dressing was applied to split thickness skin graft donor sites. The dressing gradually dehydrated and attached to donor site during the first days. During the clinical trials, physical and mechanical properties of NFC wound dressing were optimized by changing its composition. From patient 5 forward, NFC dressing was compared to commercial lactocapromer dressing, Suprathel® (PMI Polymedics, Germany). Epithelialization of the NFC dressing-covered donor site was faster in comparison to Suprathel®. Healthy epithelialized skin was revealed under the detached NFC dressing. NFC dressing self-detached after 11-21days for patients 1-9, while Suprathel® self-detached after 16-28days for patients 5-9. In comparison studies with patients 5-9, NFC dressing self-detached on average 4days earlier compared with Suprathel®. Lower NFC content in the material was evaluated to influence the enhanced pliability of the dressing and attachment to the wound bed. No allergic reaction or inflammatory response to NFC was observed. NFC dressing did not cause more pain for patients than the traditional methods to treat the skin graft donor sites. Based on the

    We experimentally realize and theoretically analyze narrow-band biphotons generated in a hot rubidium vapor cell by four-wave-mixing processing. A dressing laser beam is used to alternate both linear and nonlinear susceptibilities of the vapor, thereby modifying the biphoton's temporal correlation function. Most notably, the correlation time is increased from 6 to 165 ns. The biphoton shape is also shown to change as a result of the coupled-states dressing. We observed Rabi oscillations and optical precursors in hot atomic vapor cells. We also theoretically simulated biphoton correlation times as influenced by dressing-laser detuning and power, the results of which are consistent with our experiments.

    Delayed wound healing due to infection is a burden on healthcare systems, and the patient and caregiver alike. An emerging factor in infection and delayed healing is the presence development of biofilm in wounds. Biofilm is communities of microorganisms, protected by an extracellular matrix of slime in the wound, which can tolerate host defences and applied antimicrobials such as antibiotics or antimicrobial dressings. A growing evidence base exists suggesting that biofilm exists in a majority of chronic wounds, and can be a precursor to infection while causing delayed healing itself. In vivo models have demonstrated that the inflammatory, granulation and epithelialization processes of normal wound healing are impaired by biofilm presence. The challenge in the development of a new antimicrobial wound dressing was to make standard antimicrobial agents more effective against biofilm, and this was answered following extensive biofilm research and testing. A combination of metal chelator, surfactant and pH control displayed highly synergistic anti-biofilm action with 1.2% ionic silver in a carboxymethylcellulose dressing. Its effectiveness was challenged and proven in complex in vitro and in vivo wound biofilm models, followed by clinical safety and performance demonstrations in a 42-patient study and 113 clinical evaluations. Post-market surveillance was conducted on the commercially available dressing, and in a 112-case evaluation, the dressing was shown to effectively manage exudate and suspected biofilm while shifting difficult-to-heal wounds onto healing trajectories, after an average of 4 weeks of new dressing use in otherwise standard wound care protocols. This was accompanied by a low frequency of dressing related adverse events. In a second evaluation, clinical signs of infection and wound dimension data, before and after the evaluations, were also available. Following an average of 5.4 weeks of dressing use, all signs of clinical infection were reduced, from

    Healthcare systems are being challenged to manage increasing numbers of nonhealing wounds. Wound dressings are one of the first lines of defense in wound management, and numerous options exist. The oxidized regenerated cellulose (ORC)/collagen dressing may offer healthcare providers a robust and cost-effective tool for use in a variety of wounds. A multidisciplinary panel meeting was convened to discuss the use of ORC/collagen dressings in wound care and provide practice recommendations. A literature search was conducted to provide a brief review of the peer-reviewed studies published between January 2000 and March 2016 to inform the meeting. A 2-day panel meeting convened in February 2017. Healthcare providers with experience using ORC/collagen dressings. This multidisciplinary panel of 15 experts in wound healing included podiatrists, wound care specialists (doctors, certified wound care nurses, and research scientists), and an orthopedist. The literature search identified 58 articles, a majority of which were low levels of evidence (69.3% were level 3 or lower). Panel members identified wound types, such as abrasions, burns, stalled wounds, diabetic foot ulcers, and pressure injuries, where ORC/collagen dressing use could be beneficial. Panel members then provided recommendations and technical pearls for the use of ORC/collagen dressings in practice. Barriers to ORC/collagen dressing use were discussed, and potential resolutions were offered. An ORC/collagen dressing can be a critical tool for clinicians to help manage a variety of wounds. Clinical and economic studies comparing standard-of-care dressings and plain collagen dressings to ORC/collagen dressings are needed.

Those who developed this dressing realised the practical difficulties during the placement and removal of traditional dressings, used in haemodialysis units. They also realised that it this was unpleasant for the patients, and there was a risk to the catheters when removing the dressings because of the use of scissors and other cutting instruments. This new dressing solves these previously mentioned problems and at the same time contributes to the comfort of the patients. The model has been registered as a standard using model, and therefore it is protected by law and its copyright (Intellectual Property).

    Transumbilical laparoscopic-assisted appendectomy (TULAA) carries a high risk for surgical site infection. We investigated the effect of a bio-occlusive umbilical vacuum dressing on wound infection rates after TULAA for patients with acute appendicitis and compared to it with a conventional 3-port appendectomy with a nonvacuum dressing. This study was a retrospective chart review of 1377 patients (2-20 years) undergoing laparoscopic appendectomy for acute appendicitis in 2 tertiary care referral centers from January 2007 through December 2012. Twenty-two different operative technique/dressing variations were documented. The 6 technique/dressing groups with >50 patients were assessed, including a total of 1283 patients. The surgical site infection rate of the 220 patients treated with TULAA and application of an umbilical vacuum dressing with dry gauze is 1.8% (95% CI, 0.0-10.3%). This compares to an infection rate of 4.1% (95% CI, 1.3-10.5%) in 97 patients with dry dressing without vacuum. In the 395 patients who received an umbilical vacuum dressing with gauze and bacitracin, the surgical site infection rate was found to be 4.3% (95% CI, 2.7-6.8%). Application of an umbilical negative-pressure dressing with dry gauze lowers the rate of umbilical site infections in patients undergoing transumbilical laparoscopic-assisted appendectomy for acute appendicitis.

    Purpose. Silver wound dressings are widely used in the treatment of burns. Dressings differ in material characteristics, various antimicrobial activities, and ease of use. The purpose of this study was to evaluate both dressing performance and amount of pain during the dressing changes of 2 silver dressings Urgotul SSD® (Laboratoires Urgo, Chenove, France), and Contreet Ag® (Coloplast, Minneapolis, MN) in children. A retrospective cohort study was performed with 2 groups of 20 burns treated with Urgotul SSD and Contreet Ag until the wounds were healed or grafted. Seventy dressing changes in the Contreet Ag group and 67 dressing changes in the Urgotul group were evaluated. Every dressing change was assessed regarding the dressing performance (exudate, adherence, bleeding, and dressing application/removal), and pain. Pain was "absent or slight" in 61 (92%) dressing changes with Urgotul SSD, and in 60 (85%) of the dressing changes with Contreet Ag. Dressing application in the Urgotul group was more often "very easy" (n = 33; 49%) or "easy" (n = 32; 48%) than in the Contreet Ag group, "very easy" (n = 25; 35%), and "easy" (n = 42; 60%). Contreet Ag had a greater ability to absorb exudate ("very good" n = 60; 85%, and "good" n = 11; 15%) than Urgotul SSD ("very good" n = 34; 51%, and "good" n = 13; 19%). Urgotul SSD and Contreet Ag are comparable regarding pain during dressing change. The dressings differ in their ability to absorb exudate and ease of application. Both dressings provided nearly painless wound management, and therefore were highly accepted by the nurses and especially the children being treated.

    We introduce a method to dispersively detect alkali-metal atoms in radio-frequency-dressed states. In particular, we use dressed detection to measure populations and population differences of atoms prepared in their clock states. Linear birefringence of the atomic medium enables atom number detection via polarization homodyning, a form of common path interferometry. In order to achieve low technical noise levels, we perform optical sideband detection after adiabatic transformation of bare states into dressed states. The balanced homodyne signal then oscillates independently of field fluctuations at twice the dressing frequency, thus allowing for robust, phase-locked detection that circumvents low-frequency noise. Using probe pulses of two optical frequencies, we can detect both clock states simultaneously and obtain population difference as well as the total atom number. The scheme also allows for difference measurements by direct subtraction of the homodyne signals at the balanced detector, which should technically enable quantum noise limited measurements with prospects for the preparation of spin squeezed states. The method extends to other Zeeman sublevels and can be employed in a range of atomic clock schemes, atom interferometers, and other experiments using dressed atoms.

    ABSTRACT OBJECTIVE: Healthcare systems are being challenged to manage increasing numbers of nonhealing wounds. Wound dressings are one of the first lines of defense in wound management, and numerous options exist. The oxidized regenerated cellulose (ORC)/collagen dressing may offer healthcare providers a robust and cost-effective tool for use in a variety of wounds. DESIGN: A multidisciplinary panel meeting was convened to discuss the use of ORC/collagen dressings in wound care and provide practice recommendations. A literature search was conducted to provide a brief review of the peer-reviewed studies published between January 2000 and March 2016 to inform the meeting. SETTING: A 2-day panel meeting convened in February 2017. PARTICIPANTS: Healthcare providers with experience using ORC/collagen dressings. This multidisciplinary panel of 15 experts in wound healing included podiatrists, wound care specialists (doctors, certified wound care nurses, and research scientists), and an orthopedist. RESULTS: The literature search identified 58 articles, a majority of which were low levels of evidence (69.3% were level 3 or lower). Panel members identified wound types, such as abrasions, burns, stalled wounds, diabetic foot ulcers, and pressure injuries, where ORC/collagen dressing use could be beneficial. Panel members then provided recommendations and technical pearls for the use of ORC/collagen dressings in practice. Barriers to ORC/collagen dressing use were discussed, and potential resolutions were offered. CONCLUSIONS: An ORC/collagen dressing can be a critical tool for clinicians to help manage a variety of wounds. Clinical and economic studies comparing standard-of-care dressings and plain collagen dressings to ORC/collagen dressings are needed. PMID:29049055

    In recent years, adhesive wound dressings have been increasingly applied postoperatively because of their ease of use as they can be kept in place without having to cut and apply surgical tapes and they can cover a wound securely. However, if a wound dressing strongly adheres to the wound, a large amount of stratum corneum is removed from the newly formed epithelium or healthy periwound skin. Various types of adhesives are used on adhesive wound dressings and the extent of skin damage depends on how much an adhesive sticks to the wound or skin surface. We quantitatively determined and compared the amount of stratum corneum removed by eight different wound dressings including polyurethane foam using acrylic adhesive, silicone-based adhesive dressing, composite hydrocolloid and self-adhesive polyurethane foam in healthy volunteers. The results showed that wound dressings with silicone adhesive and self-adhesive polyurethane foam removed less stratum corneum, whereas composite hydrocolloid and polyurethane foam using acrylic adhesive removed more stratum corneum. © 2012 The Authors.

    Studies comparing contemporary silver dressings in burns are scarce. In a prospective, randomized, controlled study, counting 50 patients/research group, we compared two frequently used silver dressings, Acticoat™ and Aquacel(®) Ag, in the management of partial thickness burns with a predicted healing time between 7 and 21 days as assessed by laser Doppler imaging between 48 and 72h after burn. Variables investigated were related to baseline research group characteristics, wound healing, bacteriology, economics, nurse, and patient experience. Both research groups were comparably composed taking into account gender, age and burn characteristics. Similar results were obtained as to healing time and bacterial control with both silver dressings. A statistically significant difference in favor of the Aquacel(®) Ag dressing was found for average ease of use (p<0.001), average ease of application (p=0.001), patient pain (p<0.001), patient comfort with the dressing (p=0.017), silver staining (p<0.001), and cost effectiveness (p<0.001). Both silver dressings resulted in comparable healing times and bacterial control but the Aquacel(®) Ag dressing significantly increased comfort for patients as well as nurses and was significantly more cost-effective than the Acticoat™ dressing for the given indication.

    Eating disorders have a high rate of onset in school-aged children. School staff are in an excellent position to spot the early warning signs and offer support during recovery. This article explores the findings from focus groups conducted with 63 members of staff from 29 UK schools with the aims of (i) understanding whether they are in a good position to support students with eating disorders and (ii) to generate recommendations regarding school staff's training needs for spotting and supporting eating disorders. Participants took part in semi-structured focus groups. These were transcribed and analysed using content analysis principles. Five key themes emerged: (i) many staff do not have a basic understanding of eating disorders, (ii) eating disorders are taboo in the staffroom, (iii) staff do not feel comfortable talking to students about eating disorders, (iv) support is needed to ensure the teacher-parent relationship is a positive one and (v) school staff would welcome practical ideas for how they can best support students during the recovery period. The findings show that school staff currently feel ill-equipped to support students with eating disorders and endorse a need for focused training for school staff to better enable them to support students with eating disorders.

    Autologous cell-spray grafting of non-cultured epidermal cells is an innovative approach for the treatment of severe second-degree burns. After treatment, wounds are covered with dressings that are widely used in wound care management; however, little is known about the effects of wound dressings on individually isolated cells. The sprayed cells have to actively attach, spread, proliferate, and migrate in the wound for successful re-epithelialization, during the healing process. It is expected that exposure to wound dressing material might interfere with cell survival, attachment, and expansion. Two experiments were performed to determine whether some dressing materials have a negative impact during the early phases of wound healing. In one experiment, freshly isolated cells were seeded and cultured for one week in combination with eight different wound dressings used during burn care. Cells, which were seeded and cultured with samples of Adaptic(®), Xeroform(®), EZ Derm(®), and Mepilex(®) did not attach, nor did they survive during the first week. Mepitel(®), N-Terface(®), Polyskin(®), and Biobrane(®) dressing samples had no negative effect on cell attachment and cell growth when compared to the controls. In a second experiment, the same dressings were exposed to pre-cultured cells in order to exclude the effects of attachment and spreading. The results confirm the above findings. This study could be of interest for establishing skin cell grafting therapies in burn medicine and also for wound care in general. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

    To investigate whether there is a difference between the efficacy of honey and sugar as wound dressings. Patients with open or infected wounds were randomised to receive either honey or sugar dressings. Bacterial colonisation, wound size, wound ASEPSIS score and pain were assessed at the start of treatment and at weekly intervals until full healing occurred. Forty patients were enrolled; 18 received sugar dressings and 22 honey dressings. In the honey group, 55% of patients had positive wound cultures at the start of treatment and 23% at one week, compared with 52% and 39% respectively in the sugar group.The median rate of healing in the first two weeks of treatment was 3.8cm2/week for the honey group and 2.2cm2/week for the sugar group. After three weeks of treatment 86% of patients treated with honey had no pain during dressing changes, compared with 72% treated with sugar. Honey appears to be more effective than sugar in reducing bacterial contamination and promoting wound healing, and slightly less painful than sugar during dressing changes and motion.

    Many new dressings have been developed since the early 1980s. Wound healing comprises cleansing, granulation/vascularization, and epithelialization phases. An optimum microenvironment and the absence of cytotoxic factors are essential for epithelialization. This study examines the effect of extracts of different wound dressings on keratinocyte survival and proliferation. Keratinocyte cultures were exposed for 40 hours to at least three extracts of each of the following wound dressings, which were tested in octuplicate: Acticoat, Aquacel-Ag, Aquacel, Algisite M, Avance, Comfeel Plus transparent, Contreet-H, Hydrasorb, and SeaSorb. Silicone extract provided the reference material. Controls were included of cells cultured in medium that had been incubated under conditions identical to those used with the extracts. Cell survival (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide reduction) and proliferation (5-bromo-2':-deoxyuridine incorporation) were measured. Extracts of silver-containing dressings (Acticoat, Aquacel-Ag, Contreet-H, and Avance) were most cytotoxic. Extracts of Hydrasorb were less cytotoxic but markedly affected keratinocyte proliferation and morphology. Extracts of alginate-containing dressings (Algisite M, SeaSorb, and Contreet-H) demonstrated high calcium concentrations, markedly reduced keratinocyte proliferation, and affected keratinocyte morphology. Extracts of Aquacel and Comfeel Plus transparent induced small but significant inhibition of keratinocyte proliferation. The principle of minimizing harm should be applied to the choice of wound dressing. Silver-based dressings are cytotoxic and should not be used in the absence of infection. Alginate dressings with high calcium content affect keratinocyte proliferation probably by triggering terminal differentiation of keratinocytes. Such dressings should be used with caution in cases in which keratinocyte proliferation is essential. All dressings should be tested in vitro before

    To develop a novel neomycin sulfate-loaded hydrogel dressing (HD), numerous neomycin sulfate-loaded HDs were prepared with various amounts of polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP) and sodium alginate (SA) using freeze-thawing technique, and their physical dressing properties, drug release, in vivo wound curing and histopathology in diabetic-induced rats were assessed. SA had a positive effect on a swelling capacity, but a negative effect on the physical dressing properties and drug release of HD. However, PVP did the opposite. In particular, the neomycin sulfate-loaded HD composed of drug, PVA, PVP and SA at the weight ratio of 1/10/0.8/0.8 had excellent swelling and bioadhesive capacity, good elasticity and fast drug release. Moreover, this HD gave more improved wound curing effect compared to the commercial product, ensured the disappearance of granulation tissue and recovered the wound tissue to normal. Therefore, this novel neomycin sulfate-loaded HD could be an effective pharmaceutical product for the treatment of wounds.

    Today there is a growing demand for safe and efficient antimicrobial dressings for infected wound treatment. The antimicrobial sorption material for VitaVallis dressings was produced by one-stage oxidation of aluminum nanopowder in water in the presence of fibrous acetylcellulose matrix. Scanning electron microscopy revealed that the material is made up of fibers of diameter 1.5–3.0 µm with adhered agglomerated alumina nanosheets. An antimicrobial study revealed a high inhibitory effect of VitaVallis against the growth of gram-negative (E.coli, P. aeruginosa) and gram-positive (S. aureus) strains. The antimicrobial activity of the dressing against microbial pathogens on the wound surface was demonstrated in inmore » vivo experiments on male rats. The dressing was also tested on volunteer patients. The testing showed reduction of the wound healing period, accelerated cleaning of the infected wound and enhanced tissue regeneration in the wound. The results demonstrate that the VitaVallis dressing can be used for the treatment of deep infected wounds.« less

    We propose and demonstrate the laser cooling and trapping of Rydberg-dressed Sr atoms. By off-resonantly coupling the excited state of a narrow (7 kHz) cooling transition to a high-lying Rydberg state, we transfer Rydberg properties such as enhanced electric polarizability to a stable magneto-optical trap operating at <1 μ K . Simulations show that it is possible to reach a regime where the long-range interaction between Rydberg-dressed atoms becomes comparable to the kinetic energy, opening a route to combining laser cooling with tunable long-range interactions.

    Background Covering insertion sites with chlorhexidine impregnated dressings has been proven to be clinically effective in reducing catheter related blood stream infections (CR-BSI). Two chlorhexidine gluconate (CHG)-impregnated dressings are commercially available, a polyurethane foam disk and a film dressing containing a chlorhexidine gluconate-impregnated gel pad. While both have demonstrated efficacy in clinical settings, the major drawback of high cost and impaired IV insertion site visibility limits their usage. A new, simple film dressing containing CHG within its adhesive layer is now available. The objective of this study was to test the in vitro antimicrobial efficacy of the new dressing in comparison to the CHG-impregnated gel dressing. Methods Quantitative aliquots of suspensions (concentration of 1.0x106 to 5.0x106 cfu/sample) of clinically relevant challenge organisms (Staphylococcus species, gram-negative bacilli, Candida albicans) were incubated in contact with the new CHG-containing film dressing, a placebo version of the same (negative control) and the commercially available CHG-impregnated gel dressing (positive control). Serial dilutions of the surviving organisms were quantified using the pour plate after 1, 3, 5, and 7 days of incubation in order to calculate an antimicrobial log10 reduction for each organism/dressing combination at each point in time. Results The new CHG-containing film dressing delivered greater than 5.0 log10 reduction throughout the 7 days on all aerobic gram-negative bacilli and Staphylococcus species tested. As of day 1 the CHG-containing film dressing provided greater than 5.0 log10 reduction on Candida albicans. There were no statistically significant differences in the log10 reduction between the two dressings tested. Conclusion The new CHG-containing film dressing was found to be as effective as the chlorhexidine gluconate-impregnated gel dressing on clinically relevant microbes. PMID:26599087

    The management of split-thickness skin graft donor sites is targeted towards promoting the healing process, reducing pain. This has been an inconclusive topic. The aim of this study was to list and to discuss the French practices in term of split-thickness skin graft (STSG) donor site dressing. Multicentric national study by questionnaire (Google Drive(®)) for the attention of the plastic and/or pediatric surgeons. The type of dressing used on skin and sclap and the rhythm of dressing changes were analyzed. The study included 26 surgical centers on 40 contacted. The alginate is mainly used (Algostéril(®)) (17/26). It is left in position until healing (13/17). Five other types of dressings have been reported: paraffin gauze (3/26), lipidocolloides (1/26), Mepitel(®) (1/26), Mepilex(®) (1/26), indifferent use of gauze or alginate dressings (4/26). Twenty-two out of 26 centers make no difference in dressing choice between skin and scalp. Medical practices did not differ between adult or pediatric departments. Cost-effectiveness has become an important issue in wound management, requiring judicious use. The lack of consensus regarding split-thickness skin graft donor site dressing and our clinical practices force us to reconsider the best therapeutic option. This study coupled with the analysis of the literature highlights the difficulties of the practitioner in choosing the best dressing. The alginate seems to get the preference of our practices by its ease of use, its absence of change (reduces pain by limiting manipulations) and its moderate cost.

    2008-01-01

    During the late-Victorian period, campaigns to "reform" middle-class women's dress were grounded in discourses on health, eugenics, declining birth rates, comfort, and aesthetics. In Britain, the United States and Germany, organized "dress reform" movements emerged in the latter half of the 19th century, while in Canada the campaign was led primarily by physicians through public health education. This article explores the discussion on women's dress in public health literature in Canadian circulation between 1860-1900 and interprets findings within a feminist poststructuralist framework that posits the understanding of women's bodies and gender regulation to be central to knowledge construction on women's dress.

  1. The design, characteristics, and application of polyurethane dressings using the electrospinning process

    NASA Astrophysics Data System (ADS)

    Kampeerapappun, Piyaporn

    In general, a dressing is used to protect and help heal wounds. There are several types of dressings on the market such as hydrocolloid, hydrogel, and medicated dressings. One technique for making a dressing is electrospinning, which is a very simple procedure used to produce fibers. Due to much smaller fiber-diameters than produced with the conventional technique, the fibers from electrospinning have unique properties: high porosity and high surface areas, which are advantageous for wound healing. In this research, the fibers were electrospun using polyurethane, TecophilicRTM or TecoflexRTM, with various additives. First, multilayer transdermal electrospun dressings, four and five-layers, were developed that allowed for the controlled release of nitric oxide (NO) from a NO2 -/ascorbic acid system encapsulated in polymer nanofibers. The amount of NO released from each wound dressing was investigated. Both the four and five-layer dressings were tested for morphology of fibers, water absorption, nitrite distribution, NO release profile after sterilization by gamma radiation, and stability. In the case of the four-layer transdermal dressing, the dressing was tested in diabetic, periodontal, and cutaneous leishmaniasis patients. Furthermore, the color change of dressing was investigated. TecophilicRTM was also spun with an antimicrobial agent, which was added to the TecophilicRTM solution to electrospin an antimicrobial dressing. The morphology of fibers was tested using an optical microscope and the water absorption, uniformity, and percent extraction of dressing were also determined. In addition, the efficiency of the antimicrobial agent in the dressing was determined according to SN 195920-1994 and ASTM 2149-01. Another NO-releasing dressing was developed employing the NO donor molecules, sodium salt of linear polyethylenimine NONOates (LPEINO-Na) and calcium salt of linear polyethylenimine NONOates (LPEINO-Ca), which were electrospun with TecophilicRTM.

  4. Tunable electromagnetically induced transparency and absorption with dressed superconducting qubits

    Ian, Hou; Liu, Yu-Xi; Nori, Franco

    2010-06-01

    Electromagnetically induced transparency and absorption (EIT and EIA) are usually demonstrated using three-level atomic systems. In contrast to the usual case, we theoretically study the EIT and EIA in an equivalent three-level system: a superconducting two-level system (qubit) dressed by a single-mode cavity field. In this equivalent system, we find that both the EIT and the EIA can be tuned by controlling the level-spacing of the superconducting qubit and hence controlling the dressed system. This tunability is due to the dressed relaxation and dephasing rates which vary parametrically with the level-spacing of the original qubit and thus affect the transition properties of the dressed qubit and the susceptibility. These dressed relaxation and dephasing rates characterize the reaction of the dressed qubit to an incident probe field. Using recent experimental data on superconducting qubits (charge, phase, and flux qubits) to demonstrate our approach, we show the possibility of experimentally realizing this proposal.

    Grounded in confirmation theory, the current research sought to explore the relationship between co-rumination of fat talk and weight control practices (i.e., binging and purging, exercising, and healthy eating behaviors), with a particular interest in whether perceptions of friends' responses during these interactions exacerbate or mitigate this relationship. Female friendship dyads completed online questionnaires at three time points across 2 weeks. Multilevel modeling analyses revealed that (a) co-rumination was positively associated with binging and purging and exercising, (b) women who perceived their friends as accepting reported less binging and purging, more exercising, and more healthy eating behaviors, (c) acceptance and challenge interacted to predict binging and purging, (d) acceptance moderated the relationships between co-rumination and binging and purging, and (e) challenge moderated the relationship between co-rumination and healthy eating behaviors.

    Purpose: Getting dressed is an activity that is of particular difficulty for many persons with dementia, given the need for hand-eye coordination, fine motor skills, and overall planning skills. Despite several studies concerning interventions to improve dressing behavior, very little is known about the dressing process as it is currently…

  8. The role of dressings in the prevention of pressure ulcers.

    Pressure ulceration is a significant global healthcare problem and represents a considerable burden on healthcare resources. Within the literature an increasing number of studies have examined the role prophylactic dressings play in redistributing pressure and helping to protect the skin from the effects of friction and shear. The use of dressings to prevent pressure ulcers may be considered a controversial issue, as previous opinion has been that dressings do not reduce the effects of pressure. This article will critically evaluate the literature to examine the role dressings play in the prevention of pressure ulceration.

  9. Plasma treatments of dressings for wound healing: a review.

    Eswaramoorthy, Nithya; McKenzie, David R

    2017-12-01

    This review covers the use of plasma technology relevant to the preparation of dressings for wound healing. The current state of knowledge of plasma treatments that have potential to provide enhanced functional surfaces for rapid and effective healing is summarized. Dressings that are specialized to the needs of individual cases of chronic wounds such as diabetic ulcers are a special focus. A summary of the biology of wound healing and a discussion of the various types of plasmas that are suitable for the customizing of wound dressings are given. Plasma treatment allows the surface energy and air permeability of the dressing to be controlled, to ensure optimum interaction with the wound. Plasmas also provide control over the surface chemistry and in cases where the plasma creates energetic ion bombardment, activation with long-lived radicals that can bind therapeutic molecules covalently to the surface of the dressing. Therapeutic innovations enabled by plasma treatment include the attachment of microRNA or antimicrobial peptides. Bioactive molecules that promote subsequent cell adhesion and proliferation can also be bound, leading to the recruitment of cells to the dressing that may be stem cells or patient-derived cells. The presence of a communicating cell population expressing factors promotes healing.

    In the present article, we propose a simple Antibiofilm Dressing's Activity Measurement (A.D.A.M.) test that allows to check in vitro a dressing's suitability against biofilm-related wound infections. To perform the test, three agar discs are covered with biofilm formed by the tested pathogen after which they are assembled one over another in the form of an agar plug and placed in the well of a 24-well plate. The top disc is covered with the analyzed dressing and the entire set is incubated for 24h. During this time, the investigated antimicrobial substance is released from the dressing and penetrates to subsequent biofilm-covered agar discs. Biofilm reduction is measured using 2,3,5-triphenyl-2H-tetrazolium chloride (TTC) spectrometric assay and the results are compared to untreated control samples (agar plug covered with biofilm and without the dressing/or with a passive dressing placed on the top disc). Furthermore, in order to standardize the differences in penetrability of the drugs released from active dressings the results can be expressed as a dimensionless value referred to as the Penetrability Index. In summary, A.D.A.M. test is simple, cheap, can be performed practically in every clinical laboratory and takes no more time than routine microbiological diagnostics. Apart from measuring the released drug's activity, the A.D.A.M. test allows to assess drug penetrability (across three agar discs), reflecting real wound conditions, where microbes are frequently hidden under the necrotic tissue or cloth. In conclusion, the A.D.A.M. test produces a high volume of data that, when analyzed, can provide a researcher with a valuable hint concerning the applicability of active dressings against specific biofilm pathogens in a particular setting.

    2015-09-01

    This article discusses the use of a foam dressing for exudate management in both chronic and acute wounds, such as surgical wounds, pressure ulcers, diabetic ulcers, trauma wounds, and leg ulcers. The primary objective of the study was to observe patients' wound progression in terms of wound size and the condition of the wound bed, when using this foam dressing as either a primary or secondary dressing. The outcome of the evaluation demonstrated that ActivHeal Foam Contact dressing effectively managed exudate. It was also observed that the dressing can assist in autolysis and support improvements in peri-wound status. Choosing an appropriate dressing to manage a wound is essential. Clinicians working in the NHS are under pressure to deliver good-quality clinical outcomes, and the ActivHeal Foam Contact dressing supports this outcome.

    There are many techniques for cosmetic surgery of the ears and also many different procedures for postoperative treatment. The postoperative dressing is described as important for a successful outcome. We present our method of postoperative dressing in the form of liquid bonding. Cyanoacrylate tissue adhesives as liquid bonding agents are used for fixation of the pinna at the mastoid area. After 10-14 days the bonding can be easily removed. No huge dressings, tapes, or plasters are necessary. The patients are satisfied with the light dressing; they do not feel ashamed to appear in public. We have found this dressing technique to be simple and economical, especially because of the use of the bonding for skin closure before. It can be used after otoplasty with an anterior or a posterior approach.

    To compare the effects of the care bundles including chlorhexidine dressing and advanced dressings on the catheter-related bloodstream infection (CRBSI) rates in pediatric hematology-oncology patients with central venous catheters (CVCs). Twenty-seven PHO patients were recruited to participate in a prospective, randomized study in Turkey. The researcher used care bundles with chlorhexidine dressing in the experimental group (n = 14), and care bundles with advanced dressings in the control group (n = 13). According to the study results, 28.6% of the patients in the experimental group had CRBSI, while this rate was 38.5% in the control group patients. The CRBSI rate in the experimental group was 3.9, and the control group had 4.4 per 1000 inpatient catheter days. There was no exit-site infection in the experimental group. However, the control group had 1.7 per 1000 inpatient catheter days. Even though there was no difference between the two groups in which the researcher implemented care bundles with chlorhexidine dressing and advanced dressings in terms of CRBSI development, there was reduction in the CRBSI rates thanks to the care bundle approach. It is possible to control the CRBSI rates using care bundles in pediatric hematology-oncology patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

    We apply a dressed perturbation theory to better organize and economize the computation of high orders of the 2-body effective action of an inspiralling post-Newtonian (PN) gravitating binary. We use the effective field theory approach with the nonrelativistic field decomposition (NRG fields). For that purpose we develop quite generally the dressing theory of a nonlinear classical field theory coupled to pointlike sources. We introduce dressed charges and propagators, but unlike the quantum theory there are no dressed bulk vertices. The dressed quantities are found to obey recursive integral equations which succinctly encode parts of the diagrammatic expansion, and are the classical version of the Schwinger-Dyson equations. Actually, the classical equations are somewhat stronger since they involve only finitely many quantities, unlike the quantum theory. Classical diagrams are shown to factorize exactly when they contain nonlinear worldline vertices, and we classify all the possible topologies of irreducible diagrams for low loop numbers. We apply the dressing program to our post-Newtonian case of interest. The dressed charges consist of the dressed energy-momentum tensor after a nonrelativistic decomposition, and we compute all dressed charges (in the harmonic gauge) appearing up to 2PN in the 2-body effective action (and more). We determine the irreducible skeleton diagrams up to 3PN and we employ the dressed charges to compute several terms beyond 2PN.

    This study compared moisture vapour transmission rate (MVTR) and wear time or fluid-handling capacities of six adhesive foam dressings to a reformulated control dressing. Standardised in vitro MVTR methodology and a previously published in vivo artificial wound model (AWM) were used. Mean inverted MVTR for the reformulated dressing was 12 750 g/m(2) /24 hours and was significantly higher than four of the six comparator dressings (P < 0·0001), which ranged from 830 to 11 360 g/m(2) /24 hours. Mean upright MVTR for the reformulated dressing was 980 g/m(2) /24 hours and was significantly different than all of the comparator dressings (P < 0·0001), which ranged from 80 to 1620 g/m(2) /24 hours (three higher/three lower). The reformulated dressing median wear time ranged from 6·1 to >7·0 days, compared with 1·0 to 3·5 days for the comparator dressings (P = 0·0012 to P < 0·0001). The median fluid volume handled ranged from 78·0 to >87 ml compared with 13·0 to 44·5 ml for the comparator dressings (P = 0·0007 to P < 0·001). Interestingly, inverted MVTR did not correspond well to the AWM. These results suggest that marked differences exist between the dressings in terms of both MVTR and wear time or fluid-handling capacity. Furthermore, high inverted MVTR does not necessarily predict longer wear time or fluid-handling capacities of absorbent dressings. © 2013 The Authors.

    ♦ Peritoneal dialysis (PD)-related infection is a common cause of catheter loss and the main reason for PD drop-out. Exit-site infection (ESI) is a pathway to developing tunnel infection and peritonitis, hence rigorous exit-site care has always been emphasized in PD therapy. The aim of this study was to evaluate the effect of exit-site dressing vs non-dressing on the rate of PD-related infection. ♦ A prospective randomized controlled study was conducted in prevalent PD patients at the Hospital Tuanku Jaafar Seremban, Negeri Sembilan, Malaysia, from April 2011 until April 2013. All patients were required to perform daily washing of the exit site with antibacterial soap during a shower. In the dressing group (n = 54), patients were required to clean their exit site using povidone-iodine after drying, followed by topical mupirocin antibiotic application to the exit site. The exit site was then covered with a sterile gauze dressing and the catheter immobilized with tape. In the non-dressing group (n = 54), patients were not required to do any further dressing after drying. They were only required to apply mupirocin cream to the exit site and then left the exit site uncovered. The catheter was immobilized with tape. The primary outcome was ESI. The secondary outcomes were evidence of tunnel infection or peritonitis. ♦ A total of 97 patients completed the study. There were a total of 12 ESI episodes: 4 episodes in 4 patients in the dressing group vs 8 episodes in 4 patients in the non-dressing group. This corresponds to 1 episode per 241.3 patient-months vs 1 episode per 111.1 patient-months in the dressing and non-dressing groups respectively. Median time to first ESI episode was shorter in the non-dressing than in the dressing group, but not significant (p = 0.25). The incidence of gram-positive ESI in both groups was similar. There were no gram-negative ESI in the non-dressing group compared with 2 in the dressing group. The peritonitis rate was 1 per 37

    Pediatric digital necrosis resulting in revision amputation is a devastating outcome following digital dressing application. We report a series of 4 pediatric patients (age: 21 months-11 years) who presented for surgical consultation related to digital ischemia and irreversible necrosis following the application of Coban digital dressings. A review of the literature demonstrated that such injuries had not previously been described. In our case series, Coban dressing was utilized as a deterrent for thumb sucking, fingertip tuft fractures with nail bed lacerations, and a phalanx fracture secondary to crush injury. All 4 children suffered digital necrosis secondary to Coban dressings and ultimately required revision amputation. We discuss risks factors, application practices, and strategies to minimize complications with digital dressings in the pediatric population with the intent of creating awareness among hand surgeons to help promote safe practices and improve patient outcomes.

    Vemurafenib is a BRAF inhibitor indicated in metastatic or unresectable melanoma in patients with BRAF mutations. Vemurafenib is frequently toxic, but the toxicity is often not serious. The third case of vemurafenib-induced drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is reported herein. The case is unusual in that the onset was early, with symptoms emerging as of day 8 of treatment. Treatment of DRESS syndrome is not currently based on precise recommendations, but systemic corticosteroid therapy is effective in serious cases. Severe toxidermias under vemurafenib are exceptional; immediate discontinuation of treatment upon diagnosis is imperative. Switching from vemurafenib to dabrafenib then seems to constitute an interesting therapeutic alternative, since its efficacy is the same but with fewer cutaneous adverse reactions. This case highlights the importance of awareness of the risk of DRESS syndrome associated with vemurafenib and monitoring for warning signs from treatment initiation. © 2015 S. Karger AG, Basel.

  19. Human neutrophil elastase and collagenase sequestration with phosphorylated cotton wound dressings.

    The design and preparation of wound dressings that redress the protease imbalance in chronic wounds is an important goal of wound healing and medical materials science. Chronic wounds contain high levels of tissue and cytokine-destroying proteases including matrix metalloprotease and neutrophil elastase. Thus, the lowering of excessive protease levels in the wound environment by wound dressing sequestration prevents the breakdown of extracellular matrix proteins and growth factors necessary for wound healing. Phosphorylated cotton wound dressings were prepared to target sequestration of proteases from chronic wound exudate through a cationic uptake binding mechanism involving salt bridge formation of the positively charged amino acid side chains of proteases with the phosphate counterions of the wound dressing fiber. Dressings were prepared by applying sodium hexametaphosphate and diammonium phosphate in separate formulations to cotton gauze by pad/dry/cure methods. Phosphorylated cotton dressings were assessed for their ability to lower elastase and collagenase activity. The phosphorylated cotton dressings lowered elastase and collagenase activity 40-80% more effectively than the untreated cotton wound dressings under conditions that mimic chronic wound exudate. Efficacy of the phosphorylated cotton was found to be related to the level of phosphorylation and a lower pH due to protonated phosphate at the surface of the dressing. The capacity of the modified gauze to sequester continued elastase secretions similar to that found in a chronic wound over a 24-h period was retained within a 80% retention of elastase sequestration and was dose-dependent.

    This is a study to compare wound healing among three types of dressings on a porcine model with deep-dermal-partial-thickness burns. The burns in this study were from eight animal trials conducted in the past for other purposes and only burns with a uniform pale appearance that had served as controls in original experiments were selected. In total, there were 57 burns in 33 pigs, using one of following three dressings: Acticoat (Silver) (3 trials), Jelonet (Gauze) (3 trials), and Solosite Gel/Jelonet (Gel/Gauze) (2 trials). The wound healing assessments included wound re-epithelialisation during a 6-week period, clinical and histological scar assessments at week 6 after burn. Of all wound healing/scar assessments, only re-epithelialisation showed statistical difference between dressings. Earlier re-epithelialisation was observed in Gel/Gauze dressings compared to Silver and/or Gauze dressings. However, this study revealed huge variation in wound healing outcome between 3 trials within both Silver and/or Gauze dressings, supported by significant differences on re-epithelialisation, clinical and histological scar measurements. In addition, it was found that larger animals healed better than smaller ones, based on weights from 21 pigs. Of all dressings, Silver delivers the best protection for wound colonization/infection. Wound colonization/infection was found to confine wound healing and lead to thinner RND in scars. From this study, we cannot find enough evidence to suggest the beneficial effect of one dressing(s) over others on burn wound healing outcome on a porcine model with small deep-dermal-partial-thickness burns with a relative small sample size.

    We present a full analysis of data from our preliminary report (Lafer-Sousa, Hermann, & Conway, 2015) and test whether #TheDress image is multistable. A multistable image must give rise to more than one mutually exclusive percept, typically within single individuals. Clustering algorithms of color-matching data showed that the dress was seen categorically, as white/gold (W/G) or blue/black (B/K), with a blue/brown transition state. Multinomial regression predicted categorical labels. Consistent with our prior hypothesis, W/G observers inferred a cool illuminant, whereas B/K observers inferred a warm illuminant; moreover, subjects could use skin color alone to infer the illuminant. The data provide some, albeit weak, support for our hypothesis that day larks see the dress as W/G and night owls see it as B/K. About half of observers who were previously familiar with the image reported switching categories at least once. Switching probability increased with professional art experience. Priming with an image that disambiguated the dress as B/K biased reports toward B/K (priming with W/G had negligible impact); furthermore, knowledge of the dress's true colors and any prior exposure to the image shifted the population toward B/K. These results show that some people have switched their perception of the dress. Finally, consistent with a role of attention and local image statistics in determining how multistable images are seen, we found that observers tended to discount as achromatic the dress component that they did not attend to: B/K reporters focused on a blue region, whereas W/G reporters focused on a golden region.

    Eating disorder is a group of physiological and psychological disorders affecting approximately 1% of the female population worldwide. Although the genetic epidemiology of eating disorder is becoming increasingly clear with accumulated studies, the underlying molecular mechanisms are still unclear. Recently, integration of various high-throughput data expanded the range of candidate genes and started to generate hypotheses for understanding potential pathogenesis in complex diseases. This article presents EDdb (Eating Disorder database), the first evidence-based gene resource for eating disorder. Fifty-nine experimentally validated genes from the literature in relation to eating disorder were collected as the core dataset. Another four datasets with 2824 candidate genes across 601 genome regions were expanded based on the core dataset using different criteria (e.g., protein-protein interactions, shared cytobands, and related complex diseases). Based on human protein-protein interaction data, we reconstructed a potential molecular sub-network related to eating disorder. Furthermore, with an integrative pathway enrichment analysis of genes in EDdb, we identified an extended adipocytokine signaling pathway in eating disorder. Three genes in EDdb (ADIPO (adiponectin), TNF (tumor necrosis factor) and NR3C1 (nuclear receptor subfamily 3, group C, member 1)) link the KEGG (Kyoto Encyclopedia of Genes and Genomes) "adipocytokine signaling pathway" with the BioCarta "visceral fat deposits and the metabolic syndrome" pathway to form a joint pathway. In total, the joint pathway contains 43 genes, among which 39 genes are related to eating disorder. As the first comprehensive gene resource for eating disorder, EDdb ( http://eddb.cbi.pku.edu.cn ) enables the exploration of gene-disease relationships and cross-talk mechanisms between related disorders. Through pathway statistical studies, we revealed that abnormal body weight caused by eating disorder and obesity may both be

  4. An evaluation of a silicone adhesive shaped heel dressing.

    PubMed

    Hampton, Sylvie

    Tissue breakdown is complex and involves many factors. Pressure ulcer development in the heels is subject to extrinsic factors such as pressure, shear, friction and moisture. The heels are the most common sites for friction and shear damage, which can lead to blistering, skin erosion and tissue breakdown (Grey et al, 2006). To address the issues of wounds that are painful on dressing removal and friable skin, Smith & Nephew has introduced a soft silicone adhesive dressing to its Allevyn dressing range. Silicone does not adhere to wounded areas and can be removed gently without trauma to the periwound area. This paper discusses the findings of a 20-patient multi-site evaluation examining the performance and acceptability of Allevyn Gentle Border Heel dressing in the management of heel wounds.

    The aim of this study was to evaluate the efficacy of both a nonantimicrobial and antimicrobial (1% silver sulfadiazine-SSD) surfactant-based wound dressing in the control of Pseudomonas aeruginosa, Enterococcus sp, Staphylococcus epidermidis, Staphylococcus aureus, and methicillin-resistant S. aureus (MRSA) biofilms. Anti-biofilm efficacy was evaluated in numerous adapted American Standards for Testing and Materials (ASTM) standard biofilm models and other bespoke biofilm models. The ASTM standard models employed included the Minimum biofilm eradication concentration (MBEC) biofilm model (ASTM E2799) and the Centers for Disease Control (CDC) biofilm reactor model (ASTM 2871). Such bespoke biofilm models included the filter biofilm model and the chamberslide biofilm model. Results showed complete kill of microorganisms within a biofilm using the antimicrobial surfactant-based wound dressing. Interestingly, the nonantimicrobial surfactant-based dressing could disrupt existing biofilms by causing biofilm detachment. Prior to biofilm detachment, we demonstrated, using confocal laser scanning microscopy (CLSM), the dispersive effect of the nonantimicrobial surfactant-based wound dressing on the biofilm within 10 minutes of treatment. Furthermore, the non-antimicrobial surfactant-based wound dressing caused an increase in microbial flocculation/aggregation, important for microbial concentration. In conclusion, this nonantimicrobial surfactant-based wound dressing leads to the effective detachment and dispersion of in vitro biofilms. The use of surfactant-based wound dressings in a clinical setting may help to disrupt existing biofilm from wound tissue and may increase the action of antimicrobial treatment. © 2017 by the Wound Healing Society.

  6. Spatial filtering, color constancy, and the color-changing dress.

    PubMed

    Dixon, Erica L; Shapiro, Arthur G

    2017-03-01

    The color-changing dress is a 2015 Internet phenomenon in which the colors in a picture of a dress are reported as blue-black by some observers and white-gold by others. The standard explanation is that observers make different inferences about the lighting (is the dress in shadow or bright yellow light?); based on these inferences, observers make a best guess about the reflectance of the dress. The assumption underlying this explanation is that reflectance is the key to color constancy because reflectance alone remains invariant under changes in lighting conditions. Here, we demonstrate an alternative type of invariance across illumination conditions: An object that appears to vary in color under blue, white, or yellow illumination does not change color in the high spatial frequency region. A first approximation to color constancy can therefore be accomplished by a high-pass filter that retains enough low spatial frequency content so as to not to completely desaturate the object. We demonstrate the implications of this idea on the Rubik's cube illusion; on a shirt placed under white, yellow, and blue illuminants; and on spatially filtered images of the dress. We hypothesize that observer perceptions of the dress's color vary because of individual differences in how the visual system extracts high and low spatial frequency color content from the environment, and we demonstrate cross-group differences in average sensitivity to low spatial frequency patterns.

  7. Real-time monitoring of moisture levels in wound dressings in vitro: an experimental study.

    McColl, David; Cartlidge, Brian; Connolly, Patricia

    2007-10-01

    Retaining an appropriate level of moisture at the interface between a healing wound and an applied dressing is considered to be critical for effective wound healing. Failure to control exudate at this interface can result in maceration or drying out of the wound surface. The ability to control moisture balance at the wound interface is therefore a key aspect of wound dressing performance. To date it has not been possible to monitor in any effective manner the distribution of moisture within dressings or how this varies with time. A new measurement system is presented based on sensors placed at the wound/dressing interface which are capable of monitoring moisture levels in real time. The system comprises a model wound bed and sensor array complete with fluid injection path to mimic exudate flow. Eight monitoring points, situated beneath the test dressing, allow the moisture profile across the complete dressing to be measured both during and after fluid injection. The system has been used to evaluate the performance of four foam dressings, a composite hydrofibre dressing and a film dressing. Stark contrasts in the performance of the wound contact layer were found between the different wound dressing types. The composite hydrofibre dressing retained moisture at the wound interface throughout the experiments while areas of the foam dressing quickly became dry, even during constant injection of fluid. The abundance of sensors allowed a moisture map of the surface of the wound dressing to be constructed, illustrating that the moisture profile was not uniform across several of the dressings tested during absorption and evaporation of liquid. These results raise questions as to how the dressings behave on a wound in vivo and indicate the need for a similar clinical monitoring system for tracking wound moisture levels.

    1994-07-01

    The effect of using semirigid dressings (SRDs) on the residual limb of individuals who have had below-knee amputations as a consequence of peripheral vascular disease was investigated, with the primary question being: Does the time to readiness for prosthetic fitting for patients treated with the SRDs differ from that of patients treated with soft dressings? Forty patients entered the study and were alternately assigned to one of two groups. Nineteen patients were assigned to the SRD group, and 21 patients were assigned to the soft dressing group. The time from surgery to readiness for prosthetic fitting was recorded for each patient. Kaplan-Meier survival curves were generated for each group, and the results were analyzed with the log-rank test. There was a difference between the two curves, and an examination of the curves suggests that the expected time to readiness for prosthetic fitting for patients treated with the SRDs would be less than half that of patients treated with soft dressings. The results suggest that a patient may be ready for prosthetic fitting sooner if treated with SRDs instead of soft dressings.

    2004-06-01

    Honey has been used for its healing properties for centuries and has been used to dress wounds with favourable results. The emergence of antibiotic resistance and growing interest in "natural" or "complementary" therapies has led to an interest in honey dressings. Much of the research to date has been related to honey's antibacterial properties. However, the healing properties claimed for honey also include stimulating new tissue growth, moist wound healing, fluid handling and promoting epithelialization. Until recently, honey had not been developed as a wound management product and was not a certified pharmaceutical device. Activon Tulle is a sterile, non-adherent dressing impregnated with Leptospermum scoparium hone. The claimed properties of honey dressings would make this a valuable addition to the dressing currently available in the primary care setting. An evaluation was undertaken involving 20 patients with a variety of wounds. A conclusion is drawn that while further research is needed, medical grade honey does appear to be a valuable addition to the wound management formulary.

It is an essential element of modern medicine and the most frequent invasive procedure performed in hospitals. However, PVCs often fail before intravenous treatment is completed: this can occur because the device is not adequately attached to the skin, allowing the PVC to fall out, leading to complications such as phlebitis (irritation or inflammation to the vein wall), infiltration (fluid leaking into surrounding tissues) or occlusion (blockage). An inadequately secured PVC also increases the risk of catheter-related bloodstream infection (CRBSI), as the pistoning action (moving back and forth in the vein) of the catheter can allow migration of organisms along the catheter and into the bloodstream. Despite the many dressings and securement devices available, the impact of different securement techniques for increasing PVC dwell time is still unclear; there is a need to provide guidance for clinicians by reviewing current studies systematically. To assess the effects of PVC dressings and securement devices on the incidence of PVC failure. We searched the following electronic databases to identify reports of relevant randomised controlled trials (RCTs): the Cochrane Wounds Group Register (searched 08 April 2015): The Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE (1946 to March 7 2015); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, March 7 2015); Ovid EMBASE (1974 to March 7 2015); and EBSCO CINAHL (1982 to March 8 2015). RCTs or cluster RCTs comparing different dressings or securement devices for the stabilisation of PVCs. Cross-over trials were ineligible for inclusion, unless data for the first treatment period could be obtained. Two review authors independently selected studies, assessed trial quality and extracted data. We contacted study authors for missing information. We used standard

  11. Modern collagen wound dressings: function and purpose.

    Collagen, which is produced by fibroblasts, is the most abundant protein in the human body. A natural structural protein, collagen is involved in all 3 phases of the wound-healing cascade. It stimulates cellular migration and contributes to new tissue development. Because of their chemotactic properties on wound fibroblasts, collagen dressings encourage the deposition and organization of newly formed collagen, creating an environment that fosters healing. Collagen-based biomaterials stimulate and recruit specific cells, such as macrophages and fibroblasts, along the healing cascade to enhance and influence wound healing. These biomaterials can provide moisture or absorption, depending on the delivery system. Collagen dressings are easy to apply and remove and are conformable. Collagen dressings are usually formulated with bovine, avian, or porcine collagen. Oxidized regenerated cellulose, a plant-based material, has been combined with collagen to produce a dressing capable of binding to and protecting growth factors by binding and inactivating matrix metalloproteinases in the wound environment. The increased understanding of the biochemical processes involved in chronic wound healing allows the design of wound care products aimed at correcting imbalances in the wound microenvironment. Traditional advanced wound care products tend to address the wound's macroenvironment, including moist wound environment control, fluid management, and controlled transpiration of wound fluids. The newer class of biomaterials and wound-healing agents, such as collagen and growth factors, targets specific defects in the chronic wound environment. In vitro laboratory data point to the possibility that these agents benefit the wound healing process at a biochemical level. Considerable evidence has indicated that collagen-based dressings may be capable of stimulating healing by manipulating wound biochemistry.

    In this paper, a pulsed fiber-laser dressing method for bronze-bonded diamond wheels was studied systematically and comprehensively. The mechanisms for the laser dressing of bronze-bonded diamond wheels were theoretically analyzed, and the key processing parameters that determine the results of laser dressing, including the laser power density, pulse overlap ratio, ablation track line overlap ratio, and number of scanning cycles, were proposed for the first time. Further, the effects of these four key parameters on the oxidation-damaged layer of the material surface, the material removal efficiency, the material surface roughness, and the average protrusion height of the diamond grains were explored and summarized through pulsed laser ablation experiments. Under the current experimental conditions, the ideal values of the laser power density, pulse overlap ratio, ablation track line overlap ratio, and number of scanning cycles were determined to be 4.2 × 107 W/cm2, 30%, 30%, and 16, respectively. Pulsed laser dressing experiments were conducted on bronze-bonded diamond wheels using the optimized processing parameters; next, both the normal and tangential grinding forces produced by the dressed grinding wheel were measured while grinding alumina ceramic materials. The results revealed that the normal and tangential grinding forces produced by the laser-dressed grinding wheel during grinding were smaller than those of grinding wheels dressed using the conventional mechanical method, indicating that the pulsed laser dressing technology provides irreplaceable advantages relative to the conventional mechanical dressing method.

    Modern dressings such as hydrocolloids, gels, and foams are typically more expensive than traditional dressings such as gauze. However, if modern dressings require fewer changes, the overall cost of treatment may be lower despite the higher initial purchase price. If healing rates are comparable or better, modern dressings also may be cost-effective. A 4-week, prospective, randomized clinical trial to assess differences in treatment costs and cost-effectiveness between a modern foam dressing and saline-soaked gauze was conducted among 36 patients (22 men, 14 women, mean age 72.8 years) with a Stage II pressure ulcer (mean duration 35 weeks) at five centers in the United States. Participants were randomized to treatment with a self-adhesive polyurethane foam (n = 20) or saline-soaked gauze dressing (n = 16). No difference in time to wound closure was observed (P = 0.817). Patients in the foam group had less frequent dressing changes (P <0.001). Total cost over the study period was lower by $466 per patient (P = 0.055) and spending on dressings was lower by $92 per patient in the foam group (P = 0.025). Cost per ulcer healed was lower by $1,517 and cost per ulcer-free day was lower by $80 for patients in the foam group. On the evidence of this study, the foam dressing is a more cost-effective treatment than saline-soaked gauze for the treatment of Stage II pressure ulcers.

  16. Optimization of the dressing parameters in cylindrical grinding based on a generalized utility function

    2016-01-01

    The existing studies, concerning the dressing process, focus on the major influence of the dressing conditions on the grinding response variables. However, the choice of the dressing conditions is often made, based on the experience of the qualified staff or using data from reference books. The optimal dressing parameters, which are only valid for the particular methods and dressing and grinding conditions, are also used. The paper presents a methodology for optimization of the dressing parameters in cylindrical grinding. The generalized utility function has been chosen as an optimization parameter. It is a complex indicator determining the economic, dynamic and manufacturing characteristics of the grinding process. The developed methodology is implemented for the dressing of aluminium oxide grinding wheels by using experimental diamond roller dressers with different grit sizes made of medium- and high-strength synthetic diamonds type ??32 and ??80. To solve the optimization problem, a model of the generalized utility function is created which reflects the complex impact of dressing parameters. The model is built based on the results from the conducted complex study and modeling of the grinding wheel lifetime, cutting ability, production rate and cutting forces during grinding. They are closely related to the dressing conditions (dressing speed ratio, radial in-feed of the diamond roller dresser and dress-out time), the diamond roller dresser grit size/grinding wheel grit size ratio, the type of synthetic diamonds and the direction of dressing. Some dressing parameters are determined for which the generalized utility function has a maximum and which guarantee an optimum combination of the following: the lifetime and cutting ability of the abrasive wheels, the tangential cutting force magnitude and the production rate of the grinding process. The results obtained prove the possibility of control and optimization of grinding by selecting particular dressing

  17. Protein matrices for wound dressings =

    Vasconcelos, Andreia Joana Costa

    Fibrous proteins such as silk fibroin (SF), keratin (K) and elastin (EL) are able to mimic the extracellular matrix (ECM) that allows their recognition under physiological conditions. The impressive mechanical properties, the environmental stability, in combination with their biocompatibility and control of morphology, provide an important basis to use these proteins in biomedical applications like protein-based wound dressings. Along time the concept of wound dressings has changed from the traditional dressings such as honey or natural fibres, used just to protect the wound from external factors, to the interactive dressings of the present. Wounds can be classified in acute that heal in the expected time frame, and chronic, which fail to heal because the orderly sequence of events is disrupted at one or more stages of the healing process. Moreover, chronic wound exudates contain high levels of tissue destructive proteolytic enzymes such as human neutrophil elastase (HNE) that need to be controlled for a proper healing. The aim of this work is to exploit the self-assemble properties of silk fibroin, keratin and elastin for the development of new protein materials to be used as wound dressings: i) evaluation of the blending effect on the physical and chemical properties of the materials; ii) development of materials with different morphologies; iii) assessment of the cytocompatibility of the protein matrices; iv) ultimately, study the ability of the developed protein matrices as wound dressings through the use of human chronic wound exudate; v) use of innovative short peptide sequences that allow to target the control of high levels of HNE found on chronic wounds. Chapter III reports the preparation of silk fibroin/keratin (SF/K) blend films by solvent casting evaporation. Two solvent systems, aqueous and acidic, were used for the preparation of films from fibroin and keratin extracted from the respective silk and wool fibres. The effect of solvent system used was

    To compare four polyurethane dressings manufactured by two different companies for use in children. Seventy-eight dressings were applied to secure either local anaesthetic creams (n = 62) or intravenous cannulae (n = 16). Each dressing was evaluated for ease of application, security and ease of removal, using a simple scoring system. 84 per cent of Opsite flexigrid and 90 per cent of Tegaderm local anaesthetic cream dressings were rated as easy or very easy to apply. Opsite flexigrid was felt to be more secure, whereas Tegaderm was easier to remove. The Tegaderm cannula dressing was easier to apply than the iv3000 dressing. There was little difference between the two brands, including costs.

    Ramundo, Janet; Pike, Catlin; Pittman, Joyce

    The purpose of this evidence-based report card is to examine the evidence and provide recommendations related to the effectiveness of prophylactic foam dressings in reducing heel pressure injuries. Do prophylactic foam dressings applied to the heel reduce heel pressure injuries for patients in the acute care setting? A search of the literature was performed by a trained university librarian that resulted in 56 articles that examined pressure injury, prevention, and prophylactic dressings. A systematic approach was used to review titles, abstracts, and text, yielding 13 studies that met inclusion criteria. Strength of the evidence was rated based on the methodology from Essential Evidence Plus: Levels of Evidence and Oxford Center for Evidence-Based Medicine. Thirteen studies were identified that met inclusion criteria; 1 was a randomized controlled trial, 2 were systematic reviews, 3 quasi-experimental cohort studies, 1 quality improvement study, 1 case series, 1 scoping review, 1 consensus panel, and 3 bench studies. All of the studies identified suggest that the use of prophylactic foam dressings reduces the development of pressure injuries on the heel when used in conjunction with a pressure injury prevention program. The strength of the evidence for the identified studies was level 1 (4 level A, 4 level B, and 5 level C). The use of prophylactic multilayer foam dressings applied to the heels, in conjunction with an evidence-based pressure injury prevention program, is recommended for prevention of pressure injuries on the heel (SORT level 1).

  1. Table talk: How mothers and adolescents across socioeconomic status discuss food.

    PubMed

    Fielding-Singh, Priya; Wang, Jennifer

    2017-08-01

    This article reports findings from a qualitative study of food practices among families of differing socioeconomic circumstances. Using in-depth interviews from sixty-two families in the San Francisco Bay Area in 2015-2016, we find socioeconomic differences in how mothers and adolescents talk about food. Across SES, mothers and adolescents engage in discussions about healthy eating. However, these conversations are more commonplace and embedded within high-SES family life than among low-SES families. Beyond conversations about 1) healthy eating, the topics of 2) food quality and 3) price are discussed to varying degrees across SES. Within high-SES families, frequent discussions of healthy eating are paired with dialogue highlighting the importance of consuming higher quality food. Price is largely absent as a topic of conversation among high-SES families. On the other end of the socioeconomic spectrum, low-SES mothers and adolescents frequently engage in conversations about price when discussing food. Mentions of food quality are rare, but when they do occur, they underscore important trade-offs between food's healthiness, quality and price. Given prior research showing the impact of dialogue between parents and adolescents on adolescents' dietary behaviors, these findings help us understand how family discussions contribute to shaping adolescents' approaches to food. An important implication is that high-SES families' discussions of food quality may strengthen messages about healthy eating, while conversations about affordability within low-SES families may highlight financial barriers to healthy eating.

    Here we report a product evaluation for a non-adherent, povidone-iodine (PVP-I) dressing, determining the clinical need for the product, performing a literature review, clinical evaluation and cost-analysis, and developing a recommendation. This evaluation included 20 patients who experienced dressing pain with the previous antimicrobial dressing. Two patients discontinued the evaluation and four ulcers were non-healing; the remaining wounds closed with the PVP-I dressing. Patients indicated a preference for the PVP-I dressing, primarily due to lack of dressing pain. The PVP-I dressing was also the most cost-efficient.

  3. Role of natural polysaccharides in radiation formation of PVA hydrogel wound dressing

    2007-02-01

    Radiation processed PVA-polysaccharides hydrogels have been observed to be suitable for producing transparent, flexible, mechanically strong, biocompatible, effective and economical hydrogel dressings. The dressings were formed in single stage irradiation process achieving gel formation and sterilization at 25-30 kGy gamma radiation dose. No synthetic plasticizers and additives were used. Different formulations containing poly-vinylalcohol (PVA) and polysaccharides selected from combinations of agar and carrageenan were used to make the dressings. The selected polysaccharides themselves form thermo-reversible gels and degrade on irradiation. Using concentration of polysaccharides as low as 0.5-2% resulted in increase of tensile strength from 45 g/cm 2 to 411 g/cm 2, elongation from 30% to 410% and water uptake from 25% to 157% with respect to PVA gel without polysaccharides. Besides improving mechanical strength, agar contributes more to elongation and carrageenan to mechanical strength of the gel dressing. PVA formulations containing the polysaccharides show significantly different pre-gel viscosities behaviour. Increasing the concentration of agar in the formulation to about 2% converts the sheet gel to paste gel useful for filling wound cavities. The results indicate that pre irradiation network structure of the formulation plays an important role in determining mechanical properties of the irradiated gel dressing. Formulations containing 7-9% PVA, 0.5-1.5% carrageenan and 0.5-1% agar gave highly effective usable hydrogel dressings. Scanning electron micrographs show highly porous structure of the gel. Clinical trials of wound dressing on human patients established safety and efficacy of the dressing. The dressing has been observed to be useful in treating burns, non-healing ulcers of diabetes, leprosy and other external wounds. The dressings are now being marketed in India under different brand names.

    To determine whether application of a silicone foam dressing is associated with decreased interface pressures when applied to the heel. Prospective, within-subjects design. The study was conducted in a community-based hospital using a convenience sample of 50 healthy volunteers with a mean age of 39.6 years and mean body mass index of 26.6; 70% were female. Application of the silicone border foam dressing was randomized between the left and right heels. Participants were asked to lie down in the supine position on a viscoelastic foam mattress. Interface pressure measurements were captured using a pressure mapping system; measurements were taken once with the dressing applied to the heel (intervention map) and once without (control map). Data were captured after a 4-minute time period allowing stabilization. Analysis was based on mean interface pressure; data points were collected for both heels in each of the 2 frames, yielding 4 observations per subject. Application of the dressing was associated with a significant decrease in average pressure measurements as compared to the heel with no dressing applied (P < .001). Application of the dressing did not impact pressure readings for the heel to which no dressing was applied (P = .53), and application of the dressing to either the left or right heel did not impact pressure readings (ie, the random effect was insignificant; P = .9). Application of a silicone border foam dressing is associated with significant reduction in interface pressure and may be considered as part of a pressure ulcer prevention program.

    When electronic excitations in a semiconductor interact with light, the relevant quasiparticles are hybrid lightmatter dressed states, or exciton-polaritons. In monolayer transition metal dichalcogenides, a class of 2D direct bandgap semiconductors, optical excitations selectively populate distinct momentum valleys with correlated spin projection. The combination of this spin-valley locking with photon dressed states can lead to new optical phenomena in these materials. We present spectroscopic measurements of valley-specific exciton-polaritons in monolayer 2D materials in distinct regimes. When a monolayer is embedded in a dielectric microcavity, strong coupling exciton-polaritons are achieved. Cavity-modified dynamics of the dressed states are inferred from emission. Polarization persists up to room temperature in monolayer MoS2, in contrast with bare material. We also show that distinct regimes of valley-polarized exciton-polaritons can be accessed with microcavity engineering by tuning system parameters such as cavity decay rate and exciton-photon coupling strength. Further, we report results showing that polarization-sensitive ultrafast spectroscopy can enable sensitive measurements of the valley optical Stark shift, a light-induced dressed state energy shift, in monolayer semiconductors such as WSe2 and MoS2. These findings demonstrate distinct approaches to manipulating the picosecond dynamics of valleysensitive dressed states in monolayer semiconductors.

    A novel cross-linked honey hydrogel dressing was developed by incorporating Malaysian honey into hydrogel dressing formulation, cross-linked and sterilized using electron beam irradiation (25 kGy). In this study, the physical properties of the prepared honey hydrogel and its wound healing efficacy on deep partial thickness burn wounds in rats were assessed. Skin samples were taken at 7, 14, 21, and 28 days after burn for histopathological and molecular evaluations. Application of honey hydrogel dressings significantly enhanced (P < 0.05) wound closure and accelerated the rate of re-epithelialization as compared to control hydrogel and OpSite film dressing. A significant decrease in inflammatory response was observed in honey hydrogel treated wounds as early as 7 days after burn (P < 0.05). Semiquantitative analysis using RT-PCR revealed that treatment with honey hydrogel significantly (P < 0.05) suppressed the expression of proinflammatory cytokines (IL-1α, IL-1β, and IL-6). The present study substantiates the potential efficacy of honey hydrogel dressings in accelerating burn wound healing. PMID:21941590

    Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous eruption that has been linked to several common drugs and drug categories, including antiepileptics, allopurinol, sulfonamides, and various antibiotics; however, because of a number of recent case reports linking psychotropic medications to this condition, DRESS is increasingly recognized among psychiatrists. We systematically reviewed all psychotropic drugs linked to DRESS syndrome, and this article summarizes the clinical management relevant to psychiatric professionals. A comprehensive search was performed using Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Database of Systematic Reviews, Web of Science, Scopus, and Litt's Drug Eruption and Reaction Database for articles published in English during the past 20 years (1996-2015) using the search terms (1) psychotropic drugs OR serotonin uptake inhibitors AND DRESS or (2) psychotropic drugs AND drug reaction (or rash) eosinophilia systemic syndrome, and all article abstracts were screened for inclusion and exclusion criteria by 3 reviewers. Two independent reviewers examined the full text of 163 articles, of which 96 (25 original articles, 12 review articles, 55 case reports, and 4 letters to the editor) were included in the systematic review. We identified 1072 cases of psychotropic drug-induced DRESS, with carbamazepine, lamotrigine, phenytoin, valproate, and phenobarbital being the most implicated drugs. Based on our review of the literature, we outline management principles that include prompt withdrawal of the causative drug, hospitalization, corticosteroid therapy, and novel treatments, including intravenous immunoglobulin, cyclophosphamide, and cyclosporine, for corticosteroid-resistant DRESS. Finally, we outline strategies for treating comorbid psychiatric illness after a DRESS reaction to the psychotropic medication. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    2017-01-01

    Wound dressings are critical for wound care because they provide a physical barrier between the injury site and outside environment, preventing further damage or infection. Wound dressings also manage and even encourage the wound healing process for proper recovery. Polysaccharide biopolymers are slowly becoming popular as modern wound dressings materials because they are naturally derived, highly abundant, inexpensive, absorbent, non-toxic and non-immunogenic. Polysaccharide biopolymers have also been processed into biomimetic platforms that offer a bioactive component in wound dressings that aid the healing process. This review primarily focuses on the fabrication and biocompatibility assessment of polysaccharide materials. Specifically, fabrication platforms such as electrospun fibers and hydrogels, their fabrication considerations and popular polysaccharides such as chitosan, alginate, and hyaluronic acid among emerging options such as arabinoxylan are discussed. A survey of biocompatibility and bioactive molecule release studies, leveraging polysaccharide’s naturally derived properties, is highlighted in the text, while challenges and future directions for wound dressing development using emerging fabrication techniques such as 3D bioprinting are outlined in the conclusion. This paper aims to encourage further investigation and open up new, disruptive avenues for polysaccharides in wound dressing material development. PMID:28952482

    Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and promote healing, and there are many options to choose from including alginate, hydrocolloid and protease-modulating dressings. Topical agents have also been used as alternatives to dressings in order to promote healing.A clear and current overview of all the evidence is required to facilitate decision-making regarding the use of dressings or topical agents for the treatment of pressure ulcers. Such a review would ideally help people with pressure ulcers and health professionals assess the best treatment options. This review is a network meta-analysis (NMA) which assesses the probability of complete ulcer healing associated with alternative dressings and topical agents. To assess the effects of dressings and topical agents for healing pressure ulcers in any care setting. We aimed to examine this evidence base as a whole, determining probabilities that each treatment is the best, with full assessment of uncertainty and evidence quality. In July 2016 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses, guidelines and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) comparing the effects of at least one of the following interventions with any other intervention in the treatment of pressure ulcers (Stage 2 or above): any dressing, or any topical agent applied directly

    Curcuma longa (turmeric) has a long history of use in medicine as a treatment for inflammatory conditions. The primary active constituent of turmeric and the one responsible for its vibrant yellow color is curcumin. Curcumin is used for treatment of wound and inflammation. It had antimicrobial and antioxidant property. It has low intrinsic toxicity and magnificent properties like with comparatively lesser side-effects. Cotton cloth is one of the most successful wound dressings which utilize the intrinsic properties of cotton fibers. Modern wound dressings, however, require other properties such as antibacterial and moisture maintaining capabilities. In this study, conventional cotton cloth was coated with Curcumin composite for achieving modern wound dressing properties. Curcumin nanocomposite is characterized. The results show that coated cotton cloth with Curcumin nanocomposite has increased drying time (74%) and water absorbency (50%). Furthermore, they show antibacterial efficiency against bacterial species present in wounds. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objective: To test whether the use of a wireless electroceutical dressing (WED) (Procellera®) in conjunction with a 5-day negative pressure wound therapy (NPWT) may reduce the number of dressing changes required per week with this therapy. Approach: At the Ohio State University Comprehensive Wound Center, chronic wound patients (n=30) undergoing NPWT were randomized into two arms following consent as approved by the institutional review board. The control arm received standard of care NPWT, where the dressing change was performed thrice a week. The test arm received the same care except that the WED was added as an interface layer and dressing change was limited to twice a week. Results: A reduced cost of care was achieved using the WED in conjunction with NPWT. Despite fewer dressing changes in wounds dressed with the WED, closure outcomes were comparable with no overt signs of any wound complication, including infection. The cost of NPWT care during the week was significantly lower (from $2918 to $2346) in the WED-treated group compared with patients in the control arm. Innovation: This work introduces a novel technology platform involving a WED, which may be used in conjunction with NPWT. If used as such, NPWT is effective in decreasing the frequency of dressing change and lowering the cost of care. Conclusion: This work points toward the benefit of using the WED combined with NPWT. A larger clinical trial investigating the cost-effectiveness of WED in wound care is warranted. PMID:26005596

Four N-halamine compounds, which possess different functional groups and chemistry, were synthesized. The N-halamine compounds, which contained oxidative chlorine, the source of antimicrobial activity, were impregnated into or coated onto standard non-antimicrobial wound dressings. N-halamine-employed wound dressings inactivated about 6 to 7 logs of Staphylococcus aureus and Pseudomonas aeruginosa bacteria in brief periods of contact time. Moreover, the N-halamine-modified wound dressings showed superior antimicrobial efficacies when compared to commercially available silver wound dressings. Zone of inhibition tests revealed that there was no significant leaching of the oxidative chlorine from the materials, and inactivation of bacteria occurred by direct contact. Shelf life stability tests showed that the dressings were stable to loss of oxidative chlorine when they were stored for 6 months in dark environmental conditions. They also remained stable under florescent lighting for up to 2 months of storage. They could be stored in opaque packaging to improve their shelf life stabilities. In vitro skin irritation testing was performed using a three-dimensional human reconstructed tissue model (EpiDerm™). No potential skin irritation was observed. In vitro cytocompatibility was also evaluated. These results indicate that N-halamine wound dressings potentially can be employed to prevent infections, while at the same time improving the healing process by eliminating undesired bacterial growth.

    Skin and soft tissue infections (SSTIs) have high rates of morbidity and mortality associated. Despite the successful treatment of some SSTIs, those affecting the subcutaneous tissue, fascia, or muscle delay the healing process and can lead to life-threatening conditions. Therefore, more effective treatments are required to deal with such pathological situations. Recently, wound dressings loaded with antimicrobial agents emerged as viable options to reduce wound bacterial colonization and infection, in order to improve the healing process. In this review, an overview of the most prominent antibacterial agents incorporated in wound dressings along with their mode of action is provided. Furthermore, the recent advances in the therapeutic approaches used in the clinic and some future perspectives regarding antibacterial wound dressings are also discussed.

    The non-woven wound dressing with core-shell structured fibers was prepared by coaxial electrospinning. The polycaprolactone (PCL) was electrospun as the fiber's core to provide mechanical strength whereas collagen was fabricated into the shell in order to utilize its good biocompatibility. Simultaneously, the silver nanoparticles (Ag-NPs) as anti-bacterial agent were loaded in the shell whereas the vitamin A palmitate (VA) as healing-promoting drug was encapsulated in the core. Resulting from the fiber's core-shell structure, the VA released from the core and Ag-NPs present in the shell can endow the dressing both heal-promoting and anti-bacteria ability simultaneously, which can greatly enhance the dressing's clinical therapeutic effect. The dressing can maintain high swelling ratio of 190% for 3 d indicating its potential application as wet dressing. Furthermore, the dressing's anti-bacteria ability against Staphylococcus aureus was proved by in vitro anti-bacteria test. The in vitro drug release test showed the sustainable release of VA within 72 h, while the cell attachment showed L929 cells can well attach on the dressing indicating its good biocompatibility. In conclusion, the fabricated nanofibrous dressing possesses multiple functions to benefit wound healing and shows promising potential for clinical application.

    Interfacing nanocellulosic-based biosensors with chronic wound dressings for protease point of care diagnostics combines functional material properties of high specific surface area, appropriate surface charge, and hydrophilicity with biocompatibility to the wound environment. Combining a protease sensor with a dressing is consistent with the concept of an intelligent dressing, which has been a goal of wound-dressing design for more than a quarter century. We present here biosensors with a nanocellulosic transducer surface (nanocrystals, nanocellulose composites, and nanocellulosic aerogels) immobilized with a fluorescent elastase tripeptide or tetrapeptide biomolecule, which has selectivity and affinity for human neutrophil elastase present in chronic wound fluid. The specific surface area of the materials correlates with a greater loading of the elastase peptide substrate. Nitrogen adsorption and mercury intrusion studies revealed gas permeable systems with different porosities (28-98%) and pore sizes (2-50 nm, 210 µm) respectively, which influence water vapor transmission rates. A correlation between zeta potential values and the degree of protease sequestration imply that the greater the negative surface charge of the nanomaterials, the greater the sequestration of positively charged neutrophil proteases. The biosensors gave detection sensitivities of 0.015-0.13 units/ml, which are at detectable human neutrophil elastase levels present in chronic wound fluid. Thus, the physical and interactive biochemical properties of the nano-based biosensors are suitable for interfacing with protease sequestrant prototype wound dressings. A discussion of the relevance of protease sensors and cellulose nanomaterials to current chronic wound dressing design and technology is included.

    Patients in intensive care units are likely to have limited mobility owing to hemodynamic instability and activity orders for bed rest. Bed rest is indicated because of the severity of the disease process, which often involves intubation, sedation, paralysis, surgical procedures, poor nutrition, low flow states, and poor circulation. These patients are predisposed to the development and/or the progression of pressure ulcers not only because of their underlying diseases, but also because of limited mobility and deconditioned states of health. To assess whether treating high-risk patients with a prophylactic sacral dressing decreases the incidence of unit-acquired sacral pressure ulcers. An evidence-based tool for identifying patients at high risk for pressure ulcers was used in 3 intensive care units at an urban tertiary care hospital and academic medical center. Those patients deemed at high risk had a prophylactic sacral dressing applied. Incidence rates were collected and compared for the 7 months preceding use of the dressings and for 7 months during the trial period when the dressing was used. After the sacral dressing began being used, the number of unit-acquired sacral pressure ulcers decreased by 3.4 to 7.6 per 1000 patient days depending on the unit. A prophylactic sacral dressing may help prevent unit-acquired sacral pressure ulcers. Implementation of an involved care team with heightened awareness and increased education along with a prophylactic sacral dressing in patients deemed high risk for skin breakdown are all essential for success. ©2016 American Association of Critical-Care Nurses.

  5. Honey as a dressing for chronic wounds in adults.

    2002-10-01

    The aim of this review was to identify whether in adults with chronic wounds the use of honey as a wound dressing improves wound management outcomes. As no randomized controlled trials or comparative studies comparing the use of honey as a chronic wound dressing with usual treatment could be found, the review is based on case studies and serial case studies. These were reviewed using a framework broadly based on wound care case study guidelines (Nelson, 2000) and cohort study guidelines (Greenhalgh and Donald, 2000). Based on the case studies reviewed, honey appears to be a useful dressing in adults with chronic wounds, but the available evidence is weak and therefore must be interpreted with caution.

    The removal of adhesive wound dressings from the wound surface involves a risk of damaging the intact stratum corneum and regenerating epithelium. Pain associated with the removal of wound dressings is a major issue for patients and medical personnel. Recently, wound dressings coated with a silicone adhesive have been developed to reduce such skin damage and pain on removal and they have received good evaluation in various clinical settings. However, there is neither a standard method to quantify whether or not the integrity of the stratum corneum and regenerating epithelium is retained or if both structures are damaged by the removal of wound dressings, nor are there standardised values with which to assess skin damage. We applied six different types of adhesive wound dressing on plain copy paper printed with black ink by a laser printer, removed the dressings, examined the adhesive-coated surface of the wound dressings using a high-power videoscope, and examined the stripped areas. Wound dressings coated with a silicone adhesive showed significantly less detachment of the stratum corneum and regenerating epithelium, followed by those coated with polyurethane, hydrocolloid, and acrylic adhesives. The assessment method utilised in this study revealed distinct differences between wound dressing types, but less variation in the evaluation outcome of each type. This assessment method may be useful for the evaluation of adhesive wound dressings, particularly during product development. However, further studies will be needed to examine the effectiveness of this assessment method in the clinical setting because the adherent properties of polyurethane and hydrocolloid adhesives may be altered by the absorption of water from the skin. © 2012 The Authors.

    Although Australians on average consume large quantities of meat, their attitudes to farm animal welfare are poorly understood. We know little about how farm animal production is discussed in Australian households or how children learn about the origins of meat. This study consisted of an online survey completed by 225 primary carers throughout Australia recruited through social media. Findings include that conversations about the origin of meat were generally stimulated by meal preparation within the home rather than visits to agricultural shows or similar activities. Parents preferred to initiate conversations with children about meat production before they were 5 years of age. Urban parents were more likely than rural parents to reveal that they were conflicted about eating meat and would be more empathetic to children who chose to stop eating meat. Rural parents were more likely than urban parents to feel that children should eat what they are given and that talking about meat is not a major issue. Both groups felt that it was important that children should know where their food comes from. The findings of this study suggest that parental attitudes to meat production and consumption influence conversations about meat origins with children. Copyright © 2016 Elsevier Ltd.

Sughra Shafi Medical Complex, Narowal, Pakistan and Bhatti International Trust (BIT) Hospital, Affiliated with Central Park Medical College, Lahore, from February 2006 to February 2010. Patients with Wagner's grade 1 and 2 ulcers were enrolled. Those patients were divided in two groups; group A (n=179) treated with honey dressing and group B (n=169) treated with normal saline dressing. Outcome measures were calculated in terms of proportion of wounds completely healed (primary outcome), wound healing time, and deterioration of wounds. Patients were followed-up for a maximum of 120 days. One hundred and thirty six wounds (75.97%) out of 179 were completely healed with honey dressing and 97 (57.39%) out of 169 wtih saline dressing (p=0.001). The median wound healing time was 18.00 (6 - 120) days (Median with IQR) in group A and 29.00 (7 - 120) days (Median with IQR) in group B (p < 0.001). The present results showed that honey is an effective dressing agent instead of conventional dressings, in treating patients of diabetic foot ulcer.

    1993-02-01

    The quantum double is shown to imply the dressing transformation on quantum compact groups and the quantum Iwasawa decompositon in the general case. Quantum dressing orbits are described explicitly as *-algebras. The dual coalgebras consisting of differential operators are related to the quantum Weyl elements. Besides, the differential geometry on a quantum leaf allows a remarkably simple construction of irreducible *-representations of the algebras of quantum functions. Representation spaces then consist of analytic functions on classical phase spaces. These representations are also interpreted in the framework of quantization in the spirit of Berezin applied to symplectic leaves on classical compact groups. Convenient “coherent states” are introduced and a correspondence between classical and quantum observables is given.

    Campaign-stimulated conversations have been shown to increase the effectiveness of antismoking campaigns. In order to explore why such effects occur, in the current study we coded the content of naturally occurring conversations. We also examined whether the short-term effects of talking, and of different types of talk, on quitting intentions were mediated through intrapersonal message responses. Using the Natural Exposure(SM) methodology, we exposed 411 smokers to 1 of 6 antismoking advertisements while they were watching television at home. Responses to the advertisement-conversation participation and content, emotional responses, personalized perceived effectiveness, and changes in intentions to quit-were measured within 3 days of exposure. Conversations were coded for appraisal of the advertisement (favorable, neutral, or unfavorable) and the presence of quitting talk and emotion talk. Mediation analyses indicated that the positive effects of talking on intention change were mediated through personalized perceived effectiveness and that the positive effects were driven by conversations that contained a favorable appraisal and/or quitting talk. Conversely, conversations that contained an unfavorable appraisal of the advertisement were negatively associated with campaign effectiveness. These findings highlight the importance of measuring interpersonal communication when evaluating campaigns and the need for further research to identify the message characteristics that predict when smokers talk and when they talk only in desirable ways.

  13. Silver deposition and tissue staining associated with wound dressings containing silver.

    Argyria is the general term used to denote a clinical condition in which excessive administration and deposition of silver causes a permanent irreversible gray-blue discoloration of the skin or mucous membranes. The amount of discoloration usually depends on the route of silver delivery (ie, oral or topical administration) along with the body's ability to absorb and excrete the administered silver compound. Argyria is accepted as a rare dermatosis but once silver particles are deposited, they remain immobile and may accumulate during the aging process. Topical application of silver salts (eg, silver nitrate solution) may lead to transient skin staining. To investigate their potential to cause skin staining, two silver-containing dressings (Hydrofiber and nanocrystalline) were applied to human skin samples taken from electively amputated lower limbs. The potential for skin discoloration was assayed using atomic absorption spectroscopy. When the dressings were hydrated with water, a significantly higher amount of silver was released from the nanocrystalline dressing compared to the Hydrofiber dressing (P <0.005), which resulted in approximately 30 times more silver deposition. In contrast, when saline was used as the hydration medium, the release rates were low for both dressings and not significantly different (silver deposition was minimal). Controlling the amount of silver released from silver-containing dressings should help reduce excessive deposition of silver into wound tissue and minimize skin staining.

    To study the effect of repeated removal of four different adhesive dressings on peri-ulcer skin using quantitative non-invasive techniques. Forty-five patients with open (n = 29) or healed (n = 16) venous leg ulcers were included. Peri-ulcer skin was treated for 14 days with patches of two different hydrocolloid-based adhesive dressings, one polyurethane adhesive and one soft silicone adhesive dressing. Normal skin of the patients' ventral forearm was also treated identically. Adhesive patches of the dressings were replaced every second day. The skin barrier function was assessed by measuring transepidermal water loss and stratum corneum hydration by measuring electrical conductance. Thirty-nine patients completed the study. The hydrocolloid adhesives increased transepidermal water loss and conductance while the polyurethane and soft silicone adhesives did not influence these parameters significantly compared with adjacent non-treated peri-ulcer skin. For normal forearm skin, similar relative effects among the four adhesives were found. Repetitive treatment with hydrocolloid-based adhesive dressings induced major functional alterations of the stratum corneum. In contrast, a polyurethane adhesive and a soft silicone adhesive dressing did not alter transepidermal water loss or conductance of peri-ulcer skin.

It could include injuries of different etiologies (pressure ulcers stage 11-111, lower limb and traumatic wounds or surgical origin), with clinical signs of local infection (at least three of the following: redness, purulent discharge, heat, edema and pain). Only one wound was included per patient. An analysis of effectiveness by intention to treat all lesions included. We recruited 103 patients who met the inclusion criteria but were collected in which 77 patients were used for nanocrystalline silver dressings in some phase of the study, They had a median of 80 years of age and 58.4% were women. By type of injury: 53.2% pressure ulcers, 31.2% lower extremity ulcers and 14.3% traumatic or surgical wounds. Over 50% of the lesions was older than eight months and a larger area of 22.75 cm2. At first, 70.1% had redness, purulent discharge 64.9%, 37.7% heat edema 42.9% and 65.8% pain. Remained in the study a median of 42.5 days at a rate of change of dressing every 2.5. During this time in 96.1% of the lesions were removed for clinical signs of local infection in a statistically significant (p < or = 0.001). 27.3% healed from injuries and those not healed, 92.9% experienced improvement, and its healing curves were statistically significant (p < 0.05). 92.2% of clinicians assessed treatment with these products as good or excellent. The use of the products used in this study consistent with the concept and PLH TIME, has proved useful in this type of injury reducing the clinical signs of infection, promoting granulation tissue and necrotic removing the burden

    We introduce dressed Wilson loops as a novel confinement observable. It consists of closed planar loops of arbitrary geometry but fixed area, and its expectation values decay with the latter. The construction of dressed Wilson loops is based on chiral condensates in response to magnetic and electric fields, thus linking different physical concepts. We present results for generalized condensates and dressed Wilson loops on dynamical lattice configurations and confirm the agreement with conventional Wilson loops in the limit of large probe mass. We comment on the renormalization of dressed Wilson loops.

  1. The role of one-shot learning in #TheDress.

    2017-03-01

    #TheDress is remarkable in two aspects. First, there is a bimodal split of the population in the perception of the dress's colors (white/gold vs. black/blue). Second, whereas interobserver variance is high, intra-observer variance is low, i.e., the percept rarely switches in a given individual. There are two plausible routes of explanations: either one-shot learning during the first presentation of the image splits observers into two different, stable populations, or the differences are caused by stable traits of observers, such as different visual systems. Here, we hid large parts of the image by white occluders. The majority of naïve participants perceived the dress as black and blue. With black occluders, the majority of observers perceived the dress as white and gold. The percept did not change when we subsequently presented the full image, arguing for a crucial role of one-shot learning. Next, we investigated whether the first fixation determines the perceived color in naïve observers. We found no such effect. It remains thus a puzzling question where the source of variability in the different percepts comes from.

    Due to reports that honey accelerates wound healing, an investigation on its role in wound contraction in fresh wounds inflicted on wistar rats was carried out. Twenty adult male wistar rats had 2cm by 2cm square wound inflicted on their right dorsolateral trunk. They were divided into two groups. The experimental group had their wounds dressed with honey while the control group had normal saline dressing. Wound dressing was done every five days and measurements taken at each dressing. Wound morphology was also assessed. Dressing with honey significantly enhanced percentage wound contraction on day 10 with value of 79.20+/-2.94 compared to control value of 53.50+/-4.32. p=0.0. The mean wound measurement on day 10 reduced significantly in honey group, 1.15+/-0.18 compared to control group 2.38+/-0.28. p=0.002. However, there was no significant difference in fibroblast count per high power field in honey group 68.0+/-2.59 compared to control 90.2+/-17.40, p=0.242. Honey dressing increased mean blood vessel count per high power field, 18.8+/-3.77 albeit non significantly when compared to control value of 13.4+/-2.44, p=0.264. Also honey dressing caused increased granulation tissue formation in wounds dressed with honey compared to control group. Our study suggests that honey dressing enhances wound contraction in fresh wounds which is one of the key features of wound healing.

    Nanofiber wound dressings have great potential for both acute and chronic wound healing. The aim of this study is to develop a wound dressing by the electrospinning method and to determine its in vitro characteristics. The viscosity and the surface tension values of the polymer solutions used in the electrospinning were measured and their suitability for electrospinning was evaluated. Nanofiber wound dressing consists of three layers. The first and the second layers are sodium alginate and chitosan nanofibers, respectively. The core of the coaxial nanofibers that comprises the third layer of the wound dressing contains 1% polycaprolactone and 4.5% collagen, the shell comprises 2.5% doxycycline and 2.5% polyethylene oxide. The developed wound dressing comprises aligned nanofibers, with a contact angle of 38°, a work of bioadhesion value of 0.485mJ/cm 2 on rat skin, a tensile strength of 2.76MPa, an elongation at break value of 7.65%, a specific surface area of 9.65m 2 /g and a porosity of 52.3%. The amount of doxycycline content was found to be 260μg/cm 2 and the complete drug release was achieved in 15min. No cytotoxic effect was shown in cell culture studies with keratinocyte cell lines. As a result of the stability studies, it was found that the morphological, mechanical, bioadhesion and wettability properties and the amount of doxycycline remained stable for a period of 12 months at 4°C/ambient humidity condition. The developed three-layered wound dressing could be an alternative for wound healing applications. Copyright © 2017 Elsevier B.V. All rights reserved.

    In the well-known "dress" photograph, people either see the dress as blue with black stripes or as white with golden stripes. We suggest that the perception of colors is guided by the scene interpretation and the inferred positions of light sources. We tested this hypothesis in two online studies using color matching to estimate the colors observers see, while controlling for individual differences in gray point bias and color discrimination. Study 1 demonstrates that the interpretation of the dress corresponds to differences in perceived colors. Moreover, people who perceive the dress as blue-and-black are two times more likely to consider the light source as frontal, than those who see the white-and-gold dress. The inferred light sources, in turn, depend on the circadian changes in ambient light. The interpretation of the scene background as a wall or a mirror is consistent with the perceived colors as well. Study 2 shows that matching provides reliable results on differing devices and replicates the findings on scene interpretation and light sources. Additionally, we show that participants' environmental lighting conditions are an important cue for perceiving the dress colors. The exact mechanisms of how environmental lighting and circadian changes influence the perceived colors of the dress deserve further investigation.

    Recent clinical research has generated interest in the use of sacral wound dressings as preventive devices for patients at risk of ulceration. This study was conducted to identify the modes of action through which dressings can add to pressure ulcer prevention, for example, shear and friction force redistribution and pressure distribution. Bench testing was performed using nine commercially available dressings. The use of dressings can reduce the amplitude of shear stress and friction reaching the skin of patients at risk. They can also effectively redirect these forces to wider areas which minimises the mechanical loads upon skeletal prominences. Dressings can redistribute pressure based upon their effective Poisson ratio and larger deflection areas, providing greater load redistribution. © 2013 The Authors.

    This study was designed to compare two approaches to negative-pressure wound therapy: 125-mmHg pressure with a polyurethane foam dressing and 75-mmHg pressure with a silicone-coated dressing. Forty patients with diabetic foot wounds, after incision and drainage or amputation for infection, were assigned randomly to negative-pressure wound therapy with 75-mmHg continuous pressure with a silicone-covered dressing (75-mmHg group) or 125-mmHg with a polyurethane foam dressing (125-mmHg group) for up to 4 weeks or until surgical closure. There was no difference in the proportion of wounds that were closed surgically (75-mmHg group, 50 percent; 125-mmHg group, 60 percent), wounds that demonstrated 50 percent wound area reduction (75-mmHg group, 65 percent; 125-mmHg group, 80 percent), or wounds that demonstrated 50 percent wound volume reduction after 4 weeks of therapy (75-mmHg group, 95 percent; 125-mmHg group, 90 percent). The authors' results suggest that there was no difference in outcomes in wounds treated with low pressure (75 mmHg) with a silicone-coated interface and high pressure (125 mmHg) with a polyurethane foam interface.

    The Dress picture recently has become a hot topic on the Internet, prompting a debate whether it was black and blue, or white and gold. To investigate The Dress color perception in both multiple sclerosis (MS) patients, characterized by frequent visual system impairment with ensuing color vision effects, and general population. We developed a questionnaire to record demographics, clinical features, and The Dress color perception, posted on general and MS-specific social networks. No statistically significant differences were observed in The Dress color perception between MS patients (n=103) and general population (n=441). Furthermore, white and gold color perception was positively associated with aging in the general population (p=0.04), whereas negatively associated with progressive course (p=0.03) and longer disease duration (p<0.001) in MS patients, independently from patients' age. The Dress black and blue or white and gold perception might be due to aging in the general population, whereas black and blue perception, despite of aging, might suggest a specific effect of the MS burden (i.e. disease duration and progression) on the visual structures specifically involved in the white and gold perception.

    To gain an understanding of Latino/Hispanic caregivers' dementia-related dressing issues, their impressions of using a "smart" context-aware dresser to coach dressing, and recommendations to improve its acceptability. The same Latina moderator conducted all the caregiver focus groups. She followed a semi-structured interview guide that was previously used with White and African American family caregivers who experienced Alzheimer's disease related dressing challenges. From that study, the Preservation of Self model emerged. Using a deductive qualitative analytic approach, we applied the thematic domains from the Preservation of Self model to ascertain relevance to Latino/Hispanic caregivers. Twenty Latino/Hispanic experienced caregivers were recruited, enrolled, and participated in one of three focus groups. The majority were female (75%) and either the spouse (25%) or adult child (35%). Striking similarities occurred with the dressing challenges and alignment with the Preservation of Self model. Ethnic differences arose in concerns over assimilation weakening the Latino culture of family caregiving. Regional clothing preferences were noted. Technology improvement recommendations for our system, called DRESS, included developing bilingual prompting dialogs and video modules using the local vernacular to improve cultural sensitivity. Caregivers identified the potential for the technology to enable user privacy, empowerment, and exercise as well as offering respite time for themselves. Findings suggest dementia-related dressing issues were shared in common by different racial/ethnic groups but the response to them was influenced by cultural dynamics. For the first time Latino/Hispanic voices are heard to reflect their positive technology impressions, concerns, and recommendations in order to begin to address the cultural digital disparities divide.

    Surgical wounds for lower extremity revascularization are prone to infection and dehiscence. Acticoat Absorbent, an antimicrobial dressing, offers sustained release of ionic silver. We hypothesized that immediate application of Acticoat as a postoperative dressing would reduce wound complications in patients undergoing leg revascularization. All infrainguinal revascularization cases involving leg incisions at a single Veterans Administration Medical Center were identified from July 1, 2002, to September 30, 2005. The control group received conventional dressings, while the treatment group received an Acticoat dressing. Wound complication rates were captured via National Surgical Quality Improvement Program data. Patient characteristics and procedure distributions were similar between groups. The wound complication rate fell 64% with utilization of the Acticoat-based dressing (control 14% [17/118], treatment 5% [7/130]; P = 0.016). An Acticoat-based dressing system offers a potentially useful, cost-effective adjunct to reduce open surgical leg revascularization wound complications.

    This prospective, randomised study compares a new transforming methacrylate dressing (TMD) with a silver-containing carboxymethylcellulose dressing (CMC-Ag) after application to split-thickness skin graft (STSG) donor sites. This was an unblinded, non-inferiority, between-patient, comparison study that involved patients admitted to a single-centre burn unit who required two skin graft donor sites. Each patient's donor sites were covered immediately after surgery: one donor site with TMD and the other with CMC-Ag. The donor sites were evaluated until healing or until 24 days post-application, whichever came first. Study endpoints were time to healing, daily pain scores, number of dressing changes, patient comfort and physicians' and patients' willingness to use the dressings in the future. Nineteen patients had both the dressings applied. No statistically significant difference was noted in time to healing between the two dressings (14·2 days using TMD compared with 13·2 days using CMC-Ag). When pain scores were compared, TMD resulted in statistically significantly less pain at three different time periods (2-5 days, 6-10 days and 11-15 days; P < 0·001 at all time periods). Patients also reported greater comfort with TMD (P < 0·001). Users rated TMD as being less easy to use because of the time and technique required for application. Reductions in pain and increased patient comfort with the use of the TMD dressing, compared with CMC-Ag, were seen as clinical benefits as these are the major issues in donor site management. © 2013 The Authors.

    Over a 6-year period, 106 women involved with men who cross-dress (mostly heterosexual transvestites) completed a questionnaire regarding themselves, their male partners, and their relationships. Interview data supplemented these questionnaires for 75% of the respondents. All respondents were recruited from nonclinical settings. The "modal" female partner was a 40-year-old Protestant, Caucasian woman, who was a firstborn child, in her first marriage. She was more likely than other women her age to be childless, and to have earned at least a 2-year college degree. She was no more likely to have had lesbian experiences or substance use problems than comparably aged American women. She had been married to her cross-dressing mate for 13 years and had known of his activities for 9 years. A quarter of women reported at least occasional sexual arousal to their mate's cross-dressing. The two variables associated with low acceptance of cross-dressing were discovery of their partner's cross-dressing after marriage and lack of sexual arousal to cross-dressing stimuli. Low acceptance was unrelated to firstborn status, amount of exposure to cross-dressing activities, or having had children. This group may be more representative of women in relationships with cross-dressing men than previous reports limited to cross-dressers and spouses who are in treatment.

    Background Individuals living with advancing stages of dementia (persons with dementia, PWDs) or other cognitive disorders do not have the luxury of remembering how to perform basic day-to-day activities, which in turn makes them increasingly dependent on the assistance of caregivers. Dressing is one of the most common and stressful activities provided by caregivers because of its complexity and privacy challenges posed during the process. Objective In preparation for in-home trials with PWDs, the aim of this study was to develop and evaluate a prototype intelligent system, the DRESS prototype, to assess its ability to provide automated assistance with dressing that can afford independence and privacy to individual PWDs and potentially provide additional freedom to their caregivers (family members and professionals). Methods This laboratory study evaluated the DRESS prototype’s capacity to detect dressing events. These events were engaged in by 11 healthy participants simulating common correct and incorrect dressing scenarios. The events ranged from donning a shirt and pants inside out or backwards to partial dressing—typical issues that challenge a PWD and their caregivers. Results A set of expected detections for correct dressing was prepared via video analysis of all participants’ dressing behaviors. In the initial phases of donning either shirts or pants, the DRESS prototype missed only 4 out of 388 expected detections. The prototype’s ability to recognize other missing detections varied across conditions. There were also some unexpected detections such as detection of the inside of a shirt as it was being put on. Throughout the study, detection of dressing events was adversely affected by the relatively smaller effective size of the markers at greater distances. Although the DRESS prototype incorrectly identified 10 of 22 cases for shirts, the prototype preformed significantly better for pants, incorrectly identifying only 5 of 22 cases. Further

    Two studies were conducted. The aims of Study 1 were (a) to generate quantitative data on the content of athletes' self-talk and (b) to examine differences in the use of self-talk in general as well as the functions of self-talk in practice and competition settings. Differences in self-talk between the sexes, sport types and skill levels were also assessed. Athletes (n = 295, mean age = 21.9 years) from a variety of sports and competitive levels completed the Self-Talk Use Questionnaire (STUQ), which was developed specifically for the study. In Study 1, single-factor between-group multivariate analyses of variance revealed significant differences across sex and sport type for the content of self-talk. Mixed-model multivariate analyses of variance revealed overall greater use of self-talk, as well as increased use of the functions of self-talk, in competition compared with practice. Moreover, individual sport athletes reported greater use of self-talk, as well as the functions of self-talk, than their team sport counterparts. In Study 2, recreational volleyball players (n = 164, mean age = 21.5 years) completed a situationally modified STUQ. The results were very similar to those of Study 1. That the content of athlete self-talk was generally positive, covert and abbreviated lends support to the application of Vygotsky's (1986) verbal self-regulation theory to the study of self-talk in sport. Researchers are encouraged to examine the effectiveness of self-talk in future studies.

    Oxygen generating biomaterials represent a new trend in regenerative medicine that aims to generate and supply oxygen at the site of requirement, to support tissue healing and regeneration. To enhance the healing of dermal wounds, we have developed a highly portable, in situ oxygen generating wound dressings that uses sodium percarbonate (SPO) and calcium peroxide (CPO) as chemical oxygen sources. The dressing continuously generated oxygen for more than 3 days, after which it was replaced. In the in vivo testing on porcine full-thickness porcine wound model, the SPO/CPO dressing showed enhanced wound healing during the 8 week study period. Quantitative measurements of wound healing related parameters, such as wound closure, reepithelialization, epidermal thickness and collagen content of dermis showed that supplying oxygen topically using the SPO/CPO dressing significantly accelerated the wound healing. An increase in neovascularization, as determined using Von Willebrand factor (vWF) and CD31 staining, was also observed in the presence of SPO/CPO dressing. This novel design for a wound dressing that contains oxygen generating biomaterials (SPO/CPO) for supplying topical oxygen, may find utility in treating various types of acute to chronic wounds. © 2015 by the Wound Healing Society.

    Bacterial nanocellulose (BNC) is widely used in biomedical applications. BNC has attracted increasing attention as a novel wound dressing material, but it has no antimicrobial activity. To get over this problem in the present study the BNC was saturated with antibiotic fusidic acid (FA). The subject of the experiment was BNC, produced by bacteria Gluconacetobacter sucrofermentans B-11267. The resulting biocomposites have high antibiotic activity against Staphylococcus aureus and can be used in medicine as a wound dressing. The structure of BNC was analyzed by atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR).

    A recent, intriguing Letter by Hawking, Perry, and Strominger suggests that soft photons and gravitons can be regarded as black hole hair and may be relevant to the black hole information paradox. In this Letter we make use of factorization theorems for infrared divergences of the S matrix to argue that by appropriately dressing in and out hard states, the soft-quanta-dependent part of the S matrix becomes essentially trivial. The information paradox can be fully formulated in terms of dressed hard states, which do not depend on soft quanta.

    Pressure ulcers, which are localised injury to the skin, or underlying tissue or both, occur when people are unable to reposition themselves to relieve pressure on bony prominences. Pressure ulcers are often difficult to heal, painful and impact negatively on the individual's quality of life. The cost implications of pressure ulcer treatment are considerable, compounding the challenges in providing cost effective, efficient health services. Efforts to prevent the development of pressure ulcers have focused on nutritional support, pressure redistributing devices, turning regimes and the application of various topical agents and dressings designed to maintain healthy skin, relieve pressure and prevent shearing forces. Although products aimed at preventing pressure ulcers are widely used, it remains unclear which, if any, of these approaches are effective in preventing the development of pressure ulcers. To evaluate the effects of dressings and topical agents on the prevention of pressure ulcers, in people of any age without existing pressure ulcers, but considered to be at risk of developing a pressure ulcer, in any healthcare setting. In February 2013 we searched the following electronic databases to identify reports of relevant randomised clinical trials (RCTs): the Cochrane Wounds Group Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Database of Abstracts of Reviews of Effects (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We included RCTs evaluating the use of dressings, topical agents, or topical agents with dressings, compared with a different dressing, topical agent, or combined topical agent and dressing, or no intervention or standard care, with the aim of preventing the development of a pressure ulcer. We assessed trials for their appropriateness for inclusion and for their risk of bias. This was done by two review

    To evaluate feasibility of an efficacy trial comparing peripherally inserted central catheter (PICC) dressing and securement techniques to prevent complications and failure. This pilot, 3-armed, randomized controlled trial was undertaken at Royal Children's Hospital and Lady Cilento Children's Hospital, Brisbane, Australia, between April 2014 and September 2015. Pediatric participants (N = 101; age range, 0-18 y) were assigned to standard care (bordered polyurethane [BPU] dressing, sutureless securement device), tissue adhesive (TA) (plus BPU dressing), or integrated securement dressings (ISDs). Average PICC dwell time was 8.1 days (range, 0.2-27.7 d). Primary outcome was trial feasibility including PICC failure. Secondary outcomes were PICC complications, dressing performance, and parent and staff satisfaction. Protocol feasibility was established. PICC failure was 6% (2/32) with standard care, 6% (2/31) with ISD, and 3% (1/32) with TA. PICC complications were 16% across all groups. TA provided immediate postoperative hemostasis, prolonging the first dressing change until 5.5 days compared with 3.5 days and 2.5 days with standard care and ISD respectively. Bleeding was the most common reason for first dressing change: standard care (n = 18; 75%), ISD (n = 11; 69%), TA (n = 4; 27%). Parental satisfaction (median 9.7/10; P = .006) and staff feedback (9.2/10; P = .002) were most positive for ISD. This research suggests safety and acceptability of different securement dressings compared with standard care; securement dressings may also reduce dressing changes after insertion. Further research is required to confirm clinically cost-effective methods to prevent PICC failure. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

    Wound dressings are designed to support the wound bed and protect it from the factors that may delay or impede its healing such as contaminations and moisture-loss, thereby facilitating and accelerating the healing process. The materials used to prepare wound dressings include natural and synthetic polymers, as well as their combinations, in the forms of films, sponges and hydrogels. Polysaccharides are naturally-occurring polymers that have been extensively used as wound dressing materials. Homopolysaccharides are a class of polysaccharides consist of only one type of monosaccharide. The current review intends to overview the studies in which wound dressings from naturally-occurring polymers, based on homopolysaccharides, were prepared and evaluated. Homopolysaccharides such as cellulose, chitosan, chitin, pullulan, starch and β-glucan were considered. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2013-01-01

    Background One of the major risk variables for surgical site infection is wound management. Understanding infection risk factors for breast operations is essential in order to develop infection-prevention strategies and improve surgical outcomes. The aim of this trial is to assess the influence of dressing wear time on surgical site infection rates and skin colonization. Patients’ perception at self-assessment will also be analyzed. Methods/Design This is a two-arm randomized controlled trial. Two hundred breast cancer patients undergoing immediate or delayed breast reconstruction will be prospectively enrolled. Patients will be randomly allocated to group I (dressing removed on postoperative day one) or group II (dressing removed on postoperative day six). Surgical site infections will be defined by standard criteria from the Centers for Disease Control and Prevention (CDC). Skin colonization will be assessed by culture of samples collected at predefined time points. Patients will score dressing wear time with regard to safety, comfort and convenience. Discussion The evidence to support dressing standards for breast surgery wounds is empiric and scarce. CDC recommends protecting, with a sterile dressing for 24 to 48 hours postoperatively, a primarily closed incision, but there is no recommendation to cover this kind of incision beyond 48 hours, or on the appropriate time to shower or bathe with an uncovered incision. The results of the ongoing trial may support standard recommendations regarding dressing wear time after breast reconstruction. Trial registration ClinicalTrials.gov identifier: http://NCT01148823.

    Significance: The increasing complexity of medical and surgical care provided to pediatric patients has resulted in a population at significant risk for complications such as pressure ulcers, nonhealing surgical wounds, and moisture-associated skin damage. Wound care practices for neonatal and pediatric patients, including the choice of specific dressings or other wound care products, are currently based on a combination of provider experience and preference and a small number of published clinical guidelines based on expert opinion; rigorous evidence-based clinical guidelines for wound management in these populations is lacking. Recent Advances: Advances in the understanding of the pathophysiology of wound healing have contributed to an ever-increasing number of specialized wound care products, most of which are predominantly marketed to adult patients and that have not been evaluated for safety and efficacy in the neonatal and pediatric populations. This review aims to discuss the available data on the use of both more traditional wound care products and newer wound care technologies in these populations, including medical-grade honey, nanocrystalline silver, and soft silicone-based adhesive technology. Critical Issues: Evidence-based wound care practices and demonstration of the safety, efficacy, and appropriate utilization of available wound care dressings and products in the neonatal and pediatric populations should be established to address specific concerns regarding wound management in these populations. Future Directions: The creation and implementation of evidence-based guidelines for the treatment of common wounds in the neonatal and pediatric populations is essential. In addition to an evaluation of currently marketed wound care dressings and products used in the adult population, newer wound care technologies should also be evaluated for use in neonates and children. In addition, further investigation of the specific pathophysiology of wound healing in

    Picky eating is a childhood behavior that vexes many parents and is a symptom in the newer diagnosis of Avoidant/Restrictive Food Intake Disorder (ARFID) in adults. Pressure to eat, a parental controlling feeding practice aimed at encouraging a child to eat more, is associated with picky eating and a number of other childhood eating concerns. Low intuitive eating, an insensitivity to internal hunger and satiety cues, is also associated with a number of problem eating behaviors in adulthood. Whether picky eating and pressure to eat are predictive of young adult eating behavior is relatively unstudied. Current adult intuitive eating and disordered eating behaviors were self-reported by 170 college students, along with childhood picky eating and pressure through retrospective self- and parent reports. Hierarchical regression analyses revealed that childhood parental pressure to eat, but not picky eating, predicted intuitive eating and disordered eating symptoms in college students. These findings suggest that parental pressure in childhood is associated with problematic eating patterns in young adulthood. Additional research is needed to understand the extent to which parental pressure is a reaction to or perhaps compounds the development of problematic eating behavior. Copyright © 2015 Elsevier Ltd.

    Solowiej, Kazia; Upton, Dominic

    Wound pain can arise from the wound itself, continuing wound treatment and anticipatory pain, which occurs in some patients as a consequence of negative experiences of care. Specifically, pain caused by the removal and application of dressings has been identified as a major contributor to wound pain, from both patient and health professional perspectives. This article reviews literature on the impact of pain at dressing change, and provides practical suggestions for assessment and management of pain during wound care.

    Abstract Rationale: The life-threatening drug rash with eosinophilia and systemic symptoms (DRESS) syndrome occurs most commonly after exposure to drugs, clinical features mimic those found with other serious systemic disorders. It is rarely associated with thrombotic microangiopathy. Patient concerns: We describe the unique case of a 44-year-old man who simultaneously experienced DRESS syndrome with thrombotic microangiopathy (TMA) after a 5 days treatment with fluindione. Diagnoses: Clinical evaluation leads to the discovery of an underlying lymphangiomatosis, due to a Noonan syndrome. Intervetions: The anticoagulant was withdrawn, and corticosteroids (1 mg/kg/day) and acenocoumarol were started. Outcomes: Clinical improvement ensued. At follow-up the patient is well. Lessons: The association of DRESS with TMA is a rare condition; we believe that the presence of the underlying Noonan syndrome could have been the trigger. Moreover, we speculate about the potential interrelations between these entities. PMID:29642153

  12. Can it be harmful for parents to talk to their child about their weight? A meta-analysis.

    Many parents express concern that raising the issue of weight risks harming their child's physical self-perceptions and wellbeing. Such concerns can deter families from engaging with weight management services. This systematic review aimed to investigate the evidence behind these concerns by analysing the association between parent-child weight-talk and child wellbeing. A systematic search of eight databases identified four intervention studies and 38 associative studies. Meta-analysis was only possible for the associative studies; to facilitate more meaningful comparisons, weight-talk was categorized into four communication types and effect size estimates for the association between these and wellbeing indicators were calculated through a random effects model. Encouraging children to lose weight and criticizing weight were associated with poorer physical self-perceptions and greater dieting and dysfunctional eating (effect sizes: 0.20 to 0.47). Conversely, parental encouragement of healthy lifestyles without explicit reference to weight was associated with better wellbeing, but this was only measured in two studies. Of the four intervention studies, only one isolated the effects of parents' communication on wellbeing outcomes, reporting a positive effect. There was no effect of age on the strength of associations, but dysfunctional eating was more strongly associated with parent communication for girls than boys. The findings indicate that some forms of parent-child weight-talk are associated with poor wellbeing, but suggest that this is not inevitable. Encouraging healthy behaviours without reference to weight-control, and positive parental involvement in acknowledging and addressing weight-concern may avoid such outcomes. More longitudinal research is needed to analyse the direction of these effects. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Venous leg ulcers constitute a chronic recurring complaint that affects 1.0–1.3% of the adult population at some time in life, and which corresponds to approximately 75% of all chronic ulcers of the leg. Multilayer compression bandaging is, at present, the only treatment that has been proved to be effective in treating this type of ulcer. There is no consensus, however, about the dressings that may be applied, beneath the compression, to promote the healing of this type of ulcer, as there does not seem to be any added benefit from using special dressings rather than simple, low-adherence ones. As well as analgesia, acupuncture provokes peripheral vasodilation, in skin and muscles – which has been demonstrated both experimentally and in clinical practice – probably due to the axon reflex, among other mechanisms. The aim of the present study is to measure the effectiveness and cost of compression treatment for venous leg ulcers combined with special dressings, in comparison with low-adherence ones and acupuncture. Methods/design Cluster-randomized open-labeled trial, at 15 primary healthcare clinics in the Sevilla-Sur Healthcare District, with a control group treated with compression bandaging and low-adherence dressings; the experiment will consist, on the one hand, of the compression treatment applied in combination with special dressings (Treatment 1), and on the other, the compression treatment applied in association with low-adherence dressings, together with acupuncture (Treatment 2). Discussion The results will be measured and recorded in terms of the median time elapsed until complete healing of the ulcer, and the rate of complete healing at 3 months after beginning the treatment. An economic analysis will also be made. This study, carried out in the context of real clinical practice, will provide information for decision-taking concerning the effectiveness of special dressings. Moreover, for the first time a high-quality study will evaluate

    Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially life-threatening acute drug-induced hypersensitivity reaction. Antiepileptic drugs (AEDs) predominantly aromatic AEDs are commonly reported in DRESS. To date there are no reports of sulthiame AED causing DRESS syndrome. We report a 10-year-old girl of Indian descent with AED resistant epilepsy on maintenance sodium valproate and clonazepam. Sulthiame AED was initiated to try to improve her seizure control. Five weeks after commencing sulthiame, she developed fever with a diffuse erythematous morbilliform maculopapular rash, elevated transaminases and atypical lymphocytes. At day 3 of illness, she deteriorated with worsening elevation of liver transaminases, thrombocytopenia, progression of rash, hepatosplenomegaly, pneumonitis and markedly elevated inflammatory markers. Immunomodulatory treatment of pulse methylprednisolone was given from day 7 which was associated with improvement inflammatory markers and complete resolution of rash from day 30 of illness. The diagnosis of sulthiame-induced DRESS syndrome was made based on clinical, laboratory and skin histology findings. She was HLA-B heterozygous for HLA-B ∗ 15:123 and 15:240 and HLA-A homozygous for HLA-A ∗ 11:01:09. Both these HLA-A and HLA-B typing has not been reported before in cutaneous drug reactions. This is the first reported case of sulthiame-induced DRESS syndrome. Our case expands the list of possible susceptible HLA alleles associated with cutaneous drug reactions. It also raises the awareness of possible DRESS syndrome among patients commenced on sulthiame who will require immediate discontinuation of sulthiame and consideration of prompt treatment of corticosteroids.

  15. Mepilex Ag: an antimicrobial, absorbent foam dressing with Safetac technology.

    PubMed

    Barrett, Simon

    This article examines the role of a unique dressing-Mepilex Ag--that incorporates the rapid and sustained antimicrobial action of ionic silver with the benefits of Safetac soft silicone adhesive technology. The combined attributes of each component of this dressing allow both the control of pain and infection to be achieved simultaneously. This dual approach to the management of wounds is of significance since the evidence suggests that wound infection and the release of pro-inflammatory modulators result in both local pain and delayed healing. In this respect the control and treatment of pain is as important as the treatment of infection itself. A review of the clinical evidence relating to Safetac technology clearly demonstrates that it can be used to prevent dressing-related trauma, minimize pain at dressing change, and control exudate when used on a wide range of wound types and skin injuries. In combination with silver, this technology has been shown in in-vitro studies to have an almost instant and sustainable antimicrobial effect on a broad range of pathogens associated with delayed healing. Finally, in small clinical and case studies, Mepilex Ag has been shown to control wound bioburden and improve healing rates.

    The aim of this study was to investigate the bacterial bioburden in experimental in vitro wounds during the application of conventional negative pressure wound therapy (NPWT), with and without antimicrobial dressings (polyhexanide, silver), against NPWT instillation of octenidine. Experimental wounds produced in an in vitro porcine wound model were homogenously contaminated with bacterial suspension and treated with NPWT and different options. Group A: non-antimicrobial polyurethane foam dressing; group B: antimicrobial polyurethane foam dressing containing silver; group C: antimicrobial gauze dressing containing polyhexanide; group D: non-antimicrobial polyurethane foam dressing intermittently irrigated with octenidine; group E: negative control (non-antimicrobial polyurethane foam dressing without NPWT). Standard biopsies were harvested after 24 and 28 hours. This study demonstrated that the use of NPWT with intermitted instillation of octenidine (group D) or application of silver-based polyurethane foam dressings (group B) is significantly superior against Staphylococcus aureus colonisation in experimental wounds compared with non-antimicrobial polyurethane foam dressing (group A) after 48 hours. Surprisingly, the polyhexanide-based dressing (group C) used in this model showed no statistical significant effect compared with the control group (group E) after 24 or 48 hours of treatment. Both intermitted instillation of octenidine and silver-based dressings in standard NPWT were significantly superior compared with non-antimicrobial polyurethane foam dressings or PHMB coated gauze dressing after 48 hours.

  17. Effect of music intervention on burn patients' pain and anxiety during dressing changes.

    For burn patients, the daily dressing process causes pain and anxiety. Although drugs can relieve them, the degree of pain during dressing changes is often moderate to severe. Therefore, relevant supporting interventions, like music as an ideal intervention, could alleviate the patient's pain. This study investigated the impact of music intervention at dressing change time on burn patients' pain and anxiety. This was a prospective, randomized clinical trial; patients were randomly assigned into control (standard intervention) and experimental groups (crystal music intervention) for five consecutive days (35 patients in each group). Patients' pain and anxiety measurements were collected before, during, and after dressing changes and morphine usage was recorded. The study period was October 2014 to September 2015. There was no difference in morphine dosage for both groups. By the fourth day of music intervention, burn patients' pain before, during, and after dressing changes had significantly decreased; anxiety on the fourth day during and after dressing changes had also significantly decreased. Nurses may use ordered prescription analgesics, but if non-pharmacological interventions are increased, such as providing timely music intervention and creating a friendly, comfortable hospital environment, patients' pain and anxiety will reduce.

    To estimate the economic impact of a Tegaderm TM chlorhexidine gluconate (CHG) gel dressing compared with a standard intravenous (i.v.) dressing (defined as non-antimicrobial transparent film dressing), used for insertion site care of short-term central venous and arterial catheters (intravascular catheters) in adult critical care patients using a cost-consequence model populated with data from published sources. A decision analytical cost-consequence model was developed which assigned each patient with an indwelling intravascular catheter and a standard dressing, a baseline risk of associated dermatitis, local infection at the catheter insertion site and catheter-related bloodstream infections (CRBSI), estimated from published secondary sources. The risks of these events for patients with a Tegaderm CHG were estimated by applying the effectiveness parameters from the clinical review to the baseline risks. Costs were accrued through costs of intervention (i.e. Tegaderm CHG or standard intravenous dressing) and hospital treatment costs depended on whether the patients had local dermatitis, local infection or CRBSI. Total costs were estimated as mean values of 10,000 probabilistic sensitivity analysis (PSA) runs. Tegaderm CHG resulted in an average cost-saving of £77 per patient in an intensive care unit. Tegaderm CHG also has a 98.5% probability of being cost-saving compared to standard i.v. dressings. The analyses suggest that Tegaderm CHG is a cost-saving strategy to reduce CRBSI and the results were robust to sensitivity analyses.

    We study different dressing effects in parametrically amplified four-wave mixing (PA-FWM) processes. By seeding a weak probe laser into the Stokes or anti-Stokes channel of the FWM, the gain process is generated in the so-called bright twin beams which are the probe and conjugate beams. The dressing types dramatically affect the gain factors in both the probe and conjugate channels. The gain factor of the FWM signal decreases under the cascade-type dressing and the signal's shape splits into two dips under this dressing type. However, the intensity of the FWM signal changes from suppression to enhancement under the parallel-type dressing. We will apply this switching process to all-optical switching.

  20. French national wound management survey: choice criteria of dressings.

    PubMed

    Meaume, Sylvie; Barrois, Brigitte; Faucher, Nathalie

    Across Europe, wound care management is organized differently, and in some countries such as the UK or Denmark, wound healing centres have been implemented. In France, a large number of health professionals are not sufficiently educated in wound care management during their vocational training. The rapid evolution of dressings has changed wound management practices and has given rise to new professional recommendations. This national survey was carried out in France in 2009, including 465 health professionals, to determine the criteria they use to choose a dressing and their habits of care with acute or chronic wounds. Around 73% of respondents were nurses and, on average, participants took care of 43 wounds per month. It was also found that 89% of the health professionals who took part prefer the sequential treatment of the wound based on its appearance. Regardless of whether the wound is acute or chronic, the priorities for wound care and the choice of dressing are the management of the exudate and the prevention or treatment of infection. These results put into evidence the adequacy of the recommendations by these practitioners and the good correlation between the choice of dressing and the local therapeutic goal. To reach the same level of expertise, the professional training for health professionals who are less frequently involved in wound care is necessary.

  1. Restaurant eating in nonpurge binge-eating women.

    PubMed

    Timmerman, Gayle M

    2006-11-01

    This study describes restaurant-eating behaviors for nonpurge binge-eating women in comparison to dieters. Restaurant-eating behaviors were determined from a content analysis of 14-day food diaries using a convenience sample of 71 women who reported binging without purging and 46 dieters without a recent binge history. Comparing bingers to dieters, there were no significant differences in frequency of eating out, dessert consumption at restaurants, or fast food eating. Bingers more often perceived restaurant eating to be uncontrolled and excessive. Both bingers and dieters consumed significantly more calories (226-253 kcal) and fat (10.4-16.0 gm) on restaurant days. Extra calories consumed on restaurant-eating days may contribute to weight gain over time, especially with frequent restaurant eating. Restaurants may present a high-risk food environment for bingers and dieters, contributing to loss of control and excess consumption.

    Silver nanoparticle (AgNP)-containing dressings are used worldwide for the treatment of wounds; however, many studies have indicated that AgNPs are toxic to humans and cause cell death, primarily via apoptosis. In this study, the investigators compare the apoptotic effects of various AgNP dressing materials, with the hypothesis that nanosilver would be less toxic than ionic silver. For the in vivo experiments, Sprague-Dawley (SD) and streptozotocin (STZ)-induced diabetic rats were treated with 5 dressing materials: Aquacel Ag (product A, silver ion; ConvaTec, Berkshire, UK), Acticoat (product B, AgNP; Smith & Nephew, Fort Worth, TX), Medifoam Silver (product C, silver ion; Genewel Science Co Ltd, Seongnam, South Korea), PolyMem Silver (product D, AgNP; Ferris Mfg Corp, Fort Worth, TX), and Vaseline-impregnated dressing gauze (control; Unilever, London, UK). All treatments were applied 3 times per week. After 14 days of treatment, the SD and STZ rats were euthanized, and wound samples were examined for apoptosis. The analysis included immunohistochemistry, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, Western blotting, and reverse transcription polymerase chain reaction for a semiquantitative evaluation of apoptosis. The AgNP-containing dressing materials were more cytotoxic than the silver dressings. Compared with the AgNP dressing materials, no significant levels of apoptotic factors were observed in the silver dressing-treated wounds. The TUNEL staining showed that product C-dressed wounds contained the most apoptotic cells, while some apoptotic cells were observed in product B-dressed wounds. Moreover, apoptotic gene expression was altered, including a decline in B-cell lymphoma-2 and activation of caspase-3. This was most evident in wounds treated with product C. Interestingly, apoptotic gene expression was not induced in product A-treated wounds. Finally, product D had a relatively lower silver concentration and was less toxic

    A 42-year-old patient with epilepsy was admitted to the hospital for fever and generalized skin rash. He has known allergy to phenytoin. Valproate was started in 2012, but failed to control his seizure despite gradual increase in dosage. Phenobarbitone was added 16 days before admission and was stopped on admission. He was treated with beta-lactam antibiotics. The rash subsided gradually after the cessation of phenobarbitone. Lacosamide was subsequently added for seizure control. Unfortunately, he developed drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome soon after introduction of lacosamide that required the use of systemic steroid for acute hepatitis. A cross-reactivity with lacosamide was suspected in view of the rapid onset of DRESS syndrome after the initial rash resolution and soon after the introduction of lacosamide. We postulated that the rapid onset of DRESS syndrome may be related to the aromatic ring that is in common among phenytoin, phenobarbitone, and lacosamide.

    Exogenous application of an electric field can direct cell migration and improve wound healing; however clinical application of the therapy remains elusive due to lack of a suitable device and hence, limitations in understanding the molecular mechanisms. Here we report on a novel FDA approved redox-active Ag/Zn bioelectric dressing (BED) which generates electric fields. To develop a mechanistic understanding of how the BED may potentially influence wound re-epithelialization, we direct emphasis on understanding the influence of BED on human keratinocyte cell migration. Mapping of the electrical field generated by BED led to the observation that BED increases keratinocyte migration by three mechanisms: (i) generating hydrogen peroxide, known to be a potent driver of redox signaling, (ii) phosphorylation of redox-sensitive IGF1R directly implicated in cell migration, and (iii) reduction of protein thiols and increase in integrinαv expression, both of which are known to be drivers of cell migration. BED also increased keratinocyte mitochondrial membrane potential consistent with its ability to fuel an energy demanding migration process. Electric fields generated by a Ag/Zn BED can cross-talk with keratinocytes via redox-dependent processes improving keratinocyte migration, a critical event in wound re-epithelialization.

    Most surgical procedures involve a cut in the skin that allows the surgeon to gain access to the deeper tissues or organs. Most surgical wounds are closed fully at the end of the procedure (primary closure). The surgeon covers the closed surgical wound with either a dressing or adhesive tape. The dressing can act as a physical barrier to protect the wound until the continuity of the skin is restored (within about 48 hours) and to absorb exudate from the wound, keeping it dry and clean, and preventing bacterial contamination from the external environment. Some studies have found that the moist environment created by some dressings accelerates wound healing, although others believe that the moist environment can be a disadvantage, as excessive exudate can cause maceration (softening and deterioration) of the wound and the surrounding healthy tissue. The utility of dressing surgical wounds beyond 48 hours of surgery is, therefore, controversial. To evaluate the benefits and risks of removing a dressing covering a closed surgical incision site within 48 hours permanently (early dressing removal) or beyond 48 hours of surgery permanently with interim dressing changes allowed (delayed dressing removal), on surgical site infection.

    To assess the effect of virtual reality distraction on pain among patients with a hand injury undergoing a dressing change. Virtual reality distraction can effectively alleviate pain among patients undergoing a dressing change. Clinical research has not addressed pain control during a dressing change. A randomised controlled trial was performed. In the first dressing change sequence, 98 patients were randomly divided into an experimental group and a control group, with 49 cases in each group. Pain levels were compared between the two groups before and after the dressing change using a visual analog scale. The sense of involvement in virtual environments was measured using the Pearson correlation coefficient analysis, which determined the relationship between the sense of involvement and pain level. The difference in visual analog scale scores between the two groups before the dressing change was not statistically significant (t = 0·196, p > 0·05), but the scores became statistically significant after the dressing change (t = -30·792, p < 0·01). The correlation between the sense of involvement in a virtual environment and pain level during the dressing was statistically significant (R(2) = 0·5538, p < 0·05). Virtual reality distraction can effectively alleviate pain among patients with a hand injury undergoing a dressing change. Better results can be obtained by increasing the sense of involvement in a virtual environment. Virtual reality distraction can effectively relieve pain without side effects and is not reliant on a doctor's prescription. This tool is convenient for nurses to use, especially when analgesics are unavailable. © 2014 John Wiley & Sons Ltd.

Nanofluid-based magnetite doped with eugenol or limonene was used to fabricate modified wound dressings. Nanostructure coated materials were characterized by TEM, XRD, and FT-IR. For the quantitative measurement of biofilm-embedded microbial cells, a culture-based method for viable cell count was used. The optimized textile dressing samples proved to be more resistant to staphylococcal and pseudomonal colonization and biofilm formation compared to the uncoated controls. The functionalized surfaces for wound dressing seems to be a very useful tool for the prevention of wound microbial contamination on viable tissues.

    Wound healing dressings are increasingly needed clinically due to the large number of skin damage annually. Nitric oxide (NO) plays a key role in promoting wound healing, thus biomaterials with NO-releasing property receive increasing attention as ideal wound dressing. In present study, we prepared a novel functional wound dressing by combining electrospun poly(ε-caprolactone) (PCL) nonwoven mat with chitosan-based NO-releasing biomaterials (CS-NO). As-prepared PCL/CS-NO dressing released NO sustainably under the physiological conditions, which was controlled by the catalysis of β-galactosidase. In vivo wound healing characteristics were further evaluated on full-thickness cutaneous wounds in mice. Results showed that PCL/CS-NO wound dressings remarkably accelerated wound healing process through enhancing re-epithelialization and granulation formation and effectively improved the organization of regenerated tissues including epidermal-dermal junction, which could be ascribed to the pro-angiogenesis, immunomodulation, and enhanced collagen synthesis provided by the sustained release of NO. Therefore, PCL/CS-NO may be a promising candidate for wound dressings, especially for the chronic wound caused by the ischemia. Serious skin damage caused by trauma, surgery, burn or chronic disease has become one of the most serious clinical problems. Therefore, there is an increasing demand for ideal wound dressing that can improve wound healing. Due to the vital role of nitric oxide (NO), we developed a novel functional wound dressing by combining electrospun polycaprolactone (PCL) mat with NO-releasing biomaterial (CS-NO). The sustained release of NO from PCL/CS-NO demonstrated positive effects on wound healing, including pro-angiogenesis, immunomodulation, and enhanced collagen synthesis. Hence, wound healing process was remarkably accelerated and the organization of regenerated tissues was effectively improved as well. Taken together, PCL/CS-NO dressing may be a promising

    Objective To gain an understanding of Latino/Hispanic caregivers’ dementia-related dressing issues, their impressions of using a “smart” context-aware dresser to coach dressing, and recommendations to improve its acceptability. Method The same Latina moderator conducted all the caregiver focus groups. She followed a semi-structured interview guide that was previously used with White and African American family caregivers who experienced Alzheimer’s disease related dressing challenges. From that study, the Preservation of Self model emerged. Using a deductive qualitative analytic approach, we applied the thematic domains from the Preservation of Self model to ascertain relevance to Latino/Hispanic caregivers. Results Twenty Latino/Hispanic experienced caregivers were recruited, enrolled, and participated in one of three focus groups. The majority were female (75%) and either the spouse (25%) or adult child (35%). Striking similarities occurred with the dressing challenges and alignment with the Preservation of Self model. Ethnic differences arose in concerns over assimilation weakening the Latino culture of family caregiving. Regional clothing preferences were noted. Technology improvement recommendations for our system, called DRESS, included developing bilingual prompting dialogs and video modules using the local vernacular to improve cultural sensitivity. Caregivers identified the potential for the technology to enable user privacy, empowerment, and exercise as well as offering respite time for themselves. Conclusion Findings suggest dementia-related dressing issues were shared in common by different racial/ethnic groups but the response to them was influenced by cultural dynamics. For the first time Latino/Hispanic voices are heard to reflect their positive technology impressions, concerns, and recommendations in order to begin to address the cultural digital disparities divide.

    Active dressings (biomaterials, hydrogels) are cross-linked three-dimensional macromolecular networks. One of the most important properties of active dressings, is their ability for controlled uptake, release and retention of molecules. The formation of advanced glycation end products AGEs progressively increases with normal aging. However, AGE products are formed at accelerated rates in age and stress-related diseases (burns, in wound healing) and also in vitro. The aim will be also to develop a series of gels showing ability of controlled uptake, release and retention of molecules. The hydrogels can be used as biologically and therapeutically (antibacterial and anticancer) active biomaterials. The following materials and reagents were used in the examination: dried plants: Equisetum arvense L., Pulmonaria officinalis L., Agropyron repens. Non-defatted films were extracted from the dried plants. The suspension was stirred and extracted. Temperature was controlled using a water bath. The filtrate was vacuum condensed. The gelling precipitate was poured onto Petri plates and dried. The swelling ratio and the percent loading were calculated. The released amount of CaCl2 at different time intervals was determined by measuring the conductivity. The extent of glycation in collagen was measured. Novel types of swelling hydrogels have been prepared from dried plants and alginic acid. The active dressings showed swelling in aqueous medium, swelling characteristics were dependent on the chemical composition of hydrogel. The hydrogels were also loaded with CaCl2 and their potential for release was judged by measuring conductivity. The activity of hydrogels--active dressings on collagen incubated with glucose showed an decrease in glycation. So, hydrogels--active dressings, a known antiglycating agent which have therapeutic role in wound healing.

    Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare yet severe adverse drug-induced reaction with up to 10% mortality rate. Recent clinical trials reported an association between DRESS and telaprevir (TVR), an NS3/4A protease inhibitor of chronic hepatitis C (CHC) virus genotype 1. Its diagnosis is challenging given the variable pattern of cutaneous eruption and the myriad internal organ involvement. We present two patients who are middle-aged, obese, and white with CHC cirrhosis. They both developed a progressive diffuse, painful pruritic maculopapular rash at weeks 8 and 10 of CHC therapy with TVR, Peg-Interferon alfa-2a, and Ribavirin. They had no exposures to other medications that can cause this syndrome. Physical exam and labs and skin biopsy supported a "Definite" clinical diagnosis of DRESS, per RegiSCAR criteria. Thus Telaprevir-based triple therapy was discontinued and both patients experienced rapid resolution of the systemic symptoms with gradual improvement of eosinophilia and the skin eruption. These two cases illustrate the paramount importance of having a high index of suspicion for TVR-induced DRESS, critical for early diagnosis. Immediate discontinuation of TVR is essential in prevention of a potentially life-threatening complication. Risk factors for development of DRESS in patients receiving TVR remain to be elucidated.

    Concepts regarding the best way to treat a surgical wound vary, in literature, ranging from no dressing use to dressing maintenance for 24 to 48 hours or until suture removal. This study aimed to evaluate the influence of the length of dressing maintenance after breast augmentation with implants on cutaneous colonization and surgical site infection. This is a two-arm, parallel group, randomized clinical trial. Eighty patients who were candidates for augmentation mammoplasty with silicone implants were randomly allocated to two groups, in which the dressing was removed on postoperative day 1 (group A, n = 40) or postoperative day 6 (group B, n = 40). Cutaneous colonization was examined by culturing samples collected before and after dressing removal. The criteria defined by the Centers for Disease Control and Prevention were used to assess surgical site infection. No significant difference regarding cutaneous colonization was observed between groups before dressing application. On postoperative day 6, significantly more bacterial growth was observed in group A (p = 0.01). No surgical site infection occurred. We concluded that maintaining the dressing for 6 days led to a lower cutaneous colonization but did not influence surgical site infection rates.

    A patient with poststroke hemiparesis learns to use the nonparetic arm to compensate for the weakness of the paretic arm to achieve independence in dressing. This is the learning process of new component actions on dressing. The purpose of this study was to develop the Upper-Body Dressing Scale (UBDS) for buttoned shirt dressing, which evaluates the component actions of upper-body dressing, and to provide preliminary data on internal consistency of the UBDS, as well as its reproducibility, validity, and sensitivity to clinical change. Correlational study of concurrent validity and reliability in which 63 consecutive stroke patients were enrolled in the study and were assessed repeatedly by the UBDS and the dressing item of Functional Independent Measure (FIM). Fifty-one patients completed the 3-wk study. The Cronbach's coefficient alpha of UBDS was 0.88. The principal component analysis extracted two components, which explained 62.3% of total variance. All items of the scale had high loading on the first component (0.65-0.83). Actions on the paralytic side were the positive loadings and actions on the healthy side were the negative loadings on the second component. Intraclass correlation coefficient was 0.87. The level of correlation between UBDS score and FIM dressing item scores was -0.72. Logistic regression analysis showed that only the score of UBDS on the first day of evaluation was a significant independent predictor of dressing ability (odds ratio, 0.82; 95% confidence interval, 0.71-0.95). The UBDS scores for paralytic hand passed into the sleeve, sleeve pulled up beyond the elbow joint, and sleeve pulled up beyond the shoulder joint were worse than the score for the other components of the task. These component actions had positive loading on the second component, which was identified by the principal component analysis. The UBDS has good internal consistency, reproducibility, validity, and sensitivity to clinical changes of patients with poststroke

    To compare the performance and effectiveness of a hydrocolloid dressing (HD) and a transparent polyurethane film (PF) in preventing pressure ulcer (PU) development. The study was conducted in the intensive care unit, coronary care unit and medical clinic of the Holy House of Mercy of Passos, Brazil. Data were collected 48 hours after admission and during hospitalisation. The Braden scale was used for PU risk assessment. Consecutive eligible patients without PUs were randomly assigned by lottery to the two groups, either the HD or PF group. Of the 160 eligible patients, significant between-group differences were found in the mean total number of dressing changes (HD, 6.09±1.655 changes; PF, 5.59±2.036 changes; p=0.010), and mean number of dressing changes in the sacral region (HD, 2.50±0.871; PF, 2.05±0.825; p=0.001), with the PF group requiring significantly fewer changes than the HD group. The most common reasons for changing dressings in both groups were moisture (PF 51.1%; HD 47.9%) and shear (HD 43%; PF 38.9%), with a significant difference in shear between groups. The incidence of PUs was significantly lower (p=0.038) in the PF group (8.7%) compared with that in the HD group (15%). The results suggest that the transparent polyurethane film had a better performance and was more effective than the hydrocolloid dressing in preventing PU development.

  2. She Wears the Pants: The Reform Dress as Technology in Nineteenth-Century America.

    PubMed

    Mas, Catherine

    This article examines the American dress-reform movement, detailing the ways in which reformers conceptualized clothing as a social and bodily technology. In the mid-nineteenth century, women began making and wearing the "reform dress"-a costume consisting of pants and shortened, lightweight skirts-as an alternative to burdensome feminine fashions. When ridiculed in public for wearing overtly masculine garments, dress reformers insisted their clothing was healthful, functional, and natural. This article discusses women's use of medical science and technical knowledge in their rejection of fashion, promotion of sexual equality, and efforts to change mainstream clothing practices. When approached from a technological perspective, the reform dress reveals broader tensions in an industrializing American society, such as changing gender relations and new understandings of the relationship between humans and technology.

    I compared the effects of a just-in-time educational intervention (educational materials for dressing application attached to the manufacturer's dressing package) to traditional wound care education on reported confidence and dressing application in a simulated model. Nurses from a variety of backgrounds were recruited for this study. The nurses possessed all levels of education ranging from licensed practical nurse to master of science in nursing. Both novice and seasoned nurses were included, with no stipulations regarding years of nursing experience. Exclusion criteria included nurses who spent less than 50% of their time in direct patient care and nurses with advanced wound care training and/or certification (CWOCN, CWON). Study settings included community-based acute care facilities, critical access hospitals, long-term care facilities, long-term acute care facilities, and home care agencies. No level 1 trauma centers were included in the study for geographical reasons. Participants were randomly allocated to control or intervention groups. Each participant completed the Kent Dressing Confidence Assessment tool. Subjects were then asked to apply the dressing to a wound model under the observation of either the principal investigator or a trained observer, who scored the accuracy of dressing application according to established criteria. None of the 139 nurses who received traditional dressing packaging were able to apply the dressing to a wound model correctly. In contrast, 88% of the nurses who received the package with the educational guide attached to it were able to apply the dressing to a wound model correctly (χ2 = 107.22, df = 1, P = .0001). Nurses who received the dressing package with the attached educational guide agreed that this feature gave them confidence to correctly apply the dressing (88%), while no nurse agreed that the traditional package gave him or her the confidence to apply the dressing correctly (χ2 = 147.47, df = 4, P < .0001).

    Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe drug-induced hypersensitivity reaction characterized by skin rash, fever, blood abnormalities, and multiple organ involvement. The diagnosis of DRESS syndrome is often delayed because of its variable presentation. Prompt withdrawal of the culprit drug is the definitive treatment. DRESS syndrome induced by antituberculosis drugs has rarely been reported. A 50-year-old man admitted to our hospital with recurrent episodes of progressive rash, fever, eosinophilia, lymphadenopathy, hepatic, and pulmonary involvement were experienced after repeat trials of the same antituberculosis drugs. We diagnosed it as DRESS caused by antituberculosis drugs. The case responded well to treatment with systemic corticosteroids and intravenous immunoglobulins. However, repeated bouts of infection with methicillin-resistant Staphylococcus aureus occurred during treatment (clavicular osteomyelitis and knee septic arthritis). He was cured after treatment with linezolid. The patient was discharged on day 112. At 8-month follow-up, there was no relapse of drug eruption and joint swelling. Early diagnosis and prompt withdrawal of all suspected drugs is a key tenet of the treatment of DRESS. Our case report highlights the risks inherent in delayed diagnosis of DRESS and the challenges in the clinical management of this condition. Pulmonary manifestations with radiological changes on chest X-ray and CT can be seen in DRESS. These changes need to be differentiated from those caused by pulmonary infections. Clavicular osteomyelitis infected with MRSA may be caused by iatrogenic injury during subclavian vein catheterization. This type of MRSA infections should be treated for 4 to 6 weeks. Blood eosinophilia could be a useful marker of disease progression and treatment response in patients with DRESS. However, more experience and clinical evidence is needed to confirm this.

    Febuxostat is a xanthine oxidase inhibitor that during the last years has successfully replaced allopurinol treatment in patients with chronic kidney disease (CKD) and hyperuricemia. Several adverse events have been observed during therapy with febuxostat. DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome induced by febuxostat has been poorly described, mainly in patient with CKD who previously developed allopurinol hypersensitivity syndrome. DRESS syndrome is characterized by manifold cutaneous reactions and systemic disorders with potential devastating consequences. The underlying pathogenetic mechanisms remain unidentified, though immune responses are often complicated. P-i concept can partially explain the phenomenon. The role of renal insufficiency appears to be crucial and further investigation is required. The present article describes the case of a CKD patient that developed febuxostat-related DRESS syndrome.

    Preparation and assessments of novel absorptive wound dressing materials with efficient antimicrobial activity as well as very good cytocompatibility were described in this work. An amine terminated poly(hexamethylene guanidine hydrochloride) was prepared and used as curing agent of different epoxy-terminated polyurethane prepolymers. The structures of prepared materials were elucidated by evaluation of their (1)H NMR and FTIR spectra. The recorded tensile strength of membranes confirmed the excellent dimensional stability of the film type dressings even at fully hydrated conditions. Therefore, these dressings could protect the wound bed from external forces during the healing period. The structurally optimized dressing membranes could preserve the desired moist environment over the wounded area, as a result of their balanced equilibrium, water absorption and water vapor transmission rate. Therefore, a very good condition for stimulation of self-healing of wound bed was attained. Also, owing to the presence of guanidine hydrochloride moieties embedded into the structure of dressings, efficient antimicrobial activity against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans were detected. In vitro cytotoxicity assay of the prepared dressings revealed cytocompatibility of these materials against fibroblast cells. Therefore, they could support cell growth and proliferation at the wounded area. Copyright © 2015 Elsevier B.V. All rights reserved.

    Non-global logarithms (NGLs) are the leading manifestation of correlations between distinct phase space regions in QCD and gauge theories and have proven a challenge to understand using traditional resummation techniques. Recently, the dressed gluon ex-pansion was introduced that enables an expansion of the NGL series in terms of a “dressed gluon” building block, defined by an all-orders factorization theorem. Here, we clarify the nature of the dressed gluon expansion, and prove that it has an infinite radius of convergence as a solution to the leading logarithmic and large-N c master equation for NGLs, the Banfi-Marchesini-Smye (BMS) equation. The dressed gluonmore » expansion therefore provides an expansion of the NGL series that can be truncated at any order, with reliable uncertainty estimates. In contrast, manifest in the results of the fixed-order expansion of the BMS equation up to 12-loops is a breakdown of convergence at a finite value of α slog. We explain this finite radius of convergence using the dressed gluon expansion, showing how the dynamics of the buffer region, a region of phase space near the boundary of the jet that was identified in early studies of NGLs, leads to large contributions to the fixed order expansion. We also use the dressed gluon expansion to discuss the convergence of the next-to-leading NGL series, and the role of collinear logarithms that appear at this order. Finally, we show how an understanding of the analytic behavior obtained from the dressed gluon expansion allows us to improve the fixed order NGL series using conformal transformations to extend the domain of analyticity. Furthermore, this allows us to calculate the NGL distribution for all values of α slog from the coefficients of the fixed order expansion.« less

    Broad-spectrum antimicrobial agents, such as silver, are increasingly being formulated into medicated wound dressings in order to control colonization of wounds by opportunistic pathogens. Medicated wound dressings have been shown in-vitro to be effective against planktonic cultures, but in-vivo bacteria are likely to be present in biofilms, which makes their control and eradication more challenging. Recently, a functional wound dressing (AQUACEL(®) Ag+ Extra™ (AAg + E)) has been developed that in addition to silver contains two agents (ethylenediaminetetraacetic acid (EDTA) and benzethonium chloride (BC)) designed to disrupt biofilms. Here, the efficacy of AAg + E is demonstrated using a biofilm model developed in an isothermal microcalorimeter. The biofilm was seen to remain viable in the presence of unmedicated dressing, silver-containing dressing or silver nitrate solution. In the presence of AAg + E, however, the biofilm was eradicated. Control experiments showed that neither EDTA nor BC alone had a bactericidal effect, which means it is the synergistic action of EDTA and BC disrupting the biofilm with silver being bactericidal that leads to the product's efficacy.

    The aim of this study was to determine effectiveness of first aid dressings in extinguishing burning white phosphorous (WP), eliminating WP pieces from the surface, inhibiting re-ignition on the model (fresh bacon covered with military uniform), and preventing from late re-ignition caused by persistent WP pieces. Burning WP was extinguished with several dressings: tactical Military Dressing (WJ10), wet gauze, 2 hydrocolloids, and 3 prototypes of hydrocolloids developed by the authors. All examined dressings were effective in extinguishing WP provided that the entire area of the burning substance was completely covered. Moist gauze was especially effective in extinguishing WP, and also removed and absorbed the majority of the WP mass, preventing deeper penetration of WP particles. The immediate re-ignition was observed when all the remaining examined dressings were removed from the bacon. A stream of water was dangerous, as it splashed and transferred pieces of WP around. Moist gauze placed on burning WP for approximately 3 min was most effective in extinguishing WP and removing most of the WP pieces. We recommend moist gauze, used once or twice, as the best primary means for WP elimination and preventing tissue penetration. As a dressing used for medical evacuation (MEDEVAC), or as a second step after complete removal of visible WP, innovative hydrocolloid or hydrogel dressings should be used.

    This study examined the user voice in England's National Health Service (NHS) wound dressing supply chain. The impetus for this work came from involvement in a collaboration between industry and clinicians, entitled Woundcare Research for Appropriate Products. Experiences from that study highlighted the notable absence of research about the impact of the supply chain on the users of dressings. Interview data are presented following an outline of the grounded theory method used. These data were obtained from key stakeholders (n = 41) within the wound dressing supply chain such as nurses, manufacturers, distributors, professional organizations, government organizations and user groups. The consequences of supply disconnection revealed haphazard supply, unmet user needs and lack of information transfer between player groups. These consequences explain the lack of user voice in the supply chain and have far-reaching implications for nursing management, through purchasing decisions and nurses' management of wound care.

    We study the time evolution of the Casimir-Polder force acting on a neutral atom in front of a perfectly conducting plate, when the system starts its unitary evolution from a partially dressed state. We solve the Heisenberg equations for both atomic and field quantum operators, exploiting a series expansion with respect to the electric charge and an iterative technique. After discussing the behavior of the time-dependent force on an initially partially dressed atom, we analyze a possible experimental scheme to prepare the partially dressed state and the observability of this new dynamical effect.

    Sleep talking is very common in the general population. Its prevalence remains stable from childhood through adulthood. Sleep talking is often associated with other parasomnias: sleep walking, sleep terrors or REM sleep behavior disorders. It may arise from either REM or non REM sleep, when associated with REM sleep it is more comprehensible and often associated with clear sentences and recall of sleep mentation. Sleep talking is a benign entity and does not require any treatment; however an exceptional organic cause or psychopathology should be suspected if the onset is late (after 25 years); if the mental content is too violent or too emotional.

    Understanding why people select certain food items in everyday life is crucial for the creation of interventions to promote normal eating and to prevent the development of obesity and eating disorders. The Eating Motivation Survey (TEMS) was developed within a frame of three different studies. In Study 1, a total of 331 motives for eating behavior were generated on the basis of different data sources (previous research, nutritionist interviews, and expert discussions). In Study 2, 1250 respondents were provided with a set of motives from Study 1 and the Eating Motivation Survey was finalized. In Study 3, a sample of 1040 participants filled in the Eating Motivation Survey. Confirmatory factor analysis with fifteen factors for food choice yielded a satisfactory model fit for a full (78 items) and brief survey version (45 items) with RMSEA .048 and .037, 90% CI .047-.049 and .035-.039, respectively. Factor structure was generally invariant across random selected groups, gender, and BMI, which indicates a high stability for the Eating Motivation Survey. On the mean level, however, significant differences in motivation for food choice associated with gender, age, and BMI emerged. Implications of the fifteen distinct motivations to choose foods in everyday life are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Eating disorders are characterized by aberrant patterns of eating behavior, including such symptoms as extreme restriction of food intake or binge eating, and severe disturbances in the perception of body shape and weight, as well as a drive for thinness and obsessive fears of becoming fat. Eating disorder is an important cause for physical and psychosocial morbidity in young women. Patients with eating disorders have a deficit in the cognitive process and functional abnormalities in the brain system. Recently, brain-imaging techniques have been used to identify specific brain areas that function abnormally in patients with eating disorders. We have discussed the clinical and cognitive aspects of eating disorders and summarized neuroimaging studies of eating disorders.

    Wound dressings and other types of wound healing technologies are experiencing fast-paced development and rapid growth. As the population ages, demand will continue to rise for advanced dressings used to treat chronic wounds, such as pressure ulcers, venous stasis ulcers, and diabetic ulcers. Moist wound dressings, which facilitate natural wound healing in a cost-effective manner, will be increasingly important. In commercially available hydrogel / gauze wound dressings the gel swells to adsorb wound excreta and provide an efficient non adhesive particle barrier. An alternative to hydrogels are microgels. Essentially discrete colloidal gel particles, as a result of their very high surface area to volume ratio compared to bulk gels, they have a much faster response to external stimuli such as temperature or pH. In response to either an increase or decrease in solvent quality these porous networks shrink and swell reversibly. When swollen the interstitial regions within the polymer matrix are available for further chemistry; such as the incorporation of small molecules. The reversible shrinking and swelling as a function of external stimuli provides a novel drug release system. As the environmental conditions of a wound change over its lifetime, tending to increase in pH if there is an infection combining these discrete polymeric particles with a substrate such as cotton, results in a smart wound dressing.

    Objective To examine clinical correlates of nocturnal eating, a core behavioral symptom of night eating syndrome. Method Data from 285 women who had participated in a two-stage screening for binge eating were utilized. Women (n = 41) who reported one or more nocturnal eating episodes in the past 28 days on the Eating Disorder Examination and women who did not report nocturnal eating (n =244) were compared on eating disorder symptomatology, Body Mass Index (BMI), and on measures of psychosocial adjustment. Results Nocturnal eaters were significantly more likely to report binge eating and differed significantly from non-nocturnal eaters (with responses indicating greater disturbance) on weight and shape concern, eating concern, self-esteem, depression, and functional impairment, but not on BMI or dietary restraint. Group differences remained significant in analyses adjusting for binge eating. Conclusions This study confirms the association between nocturnal eating and binge eating previously found in treatment seeking samples yet also suggests that the elevated eating disorder symptoms and decreased psychosocial adjustment observed in nocturnal eaters is not simply a function of binge eating.

    Pressure ulcers pose a significant burden to both patients and health care resources. There are an increasing number of studies that have examined the use of prophylactic dressings, and their ability to redistribute pressure and protect the skin from shear and friction damage. This literature review examines six studies conducted on this controversial subject. Brindle and Wegelin ( 2012 ; Chaiken, 2012 ; Cubit et al, 2012 ; Santamaria et al, 2012) all examined the role of dressings to prevent pressure ulcers, and Call et al (2013a ; 2013b ), conducted in vitro research into the mode of dressings. Current research suggests that while further research is required, the use of prophylactic dressings have a place alongside standard measures, in helping to prevent pressure, shear and friction damage.

    To accelerate healing of severe hemorrhagic wounds, a novel highly absorbent hemostatic dressing composed of a Tencel®/absorbent-cotton/polylactic acid nonwoven base and chitosan/nanosilver antibacterial agent was fabricated by using a nonwoven processing technique and a freeze-drying technique. This study is the first to investigate the wicking and water-absorbing properties of a nonwoven base by measuring the vertical wicking height and water absorption ratio. Moreover, blood agglutination and hemostatic second tests were conducted to evaluate the hemostatic performance of the resultant wound dressing. The blending ratio of fibers, areal weight, punching density, and fiber orientation, all significantly influenced the vertical moisture wicking property. However, only the first two parameters markedly affected the water absorption ratio. After the nonwoven base absorbed blood, scanning electron microscope (SEM) observation showed that erythrocytes were trapped between the fibrin/clot network and nonwoven fibers when coagulation pathways were activated. Prothrombin time (PT) and activated partial thromboplastin time (APTT) blood agglutination of the resultant dressing decreased to 14.34 and 50.94 s, respectively. In the femoral artery of the rate bleeding model, hemostatic time was saved by 87.2% compared with that of cotton cloth. Therefore, the resultant antibacterial wound dressing demonstrated greater water and blood absorption, as well as hemostatic performance, than the commercially available cotton cloth, especially for healing severe hemorrhagic wounds.

    M.oleifera is a medicinal plant traditionally used for skin sores, sore throat and eye infections. Recently, the wound healing property of the leaves of M. oleifera was has been well demonstrated experimentally in both in vivo and in vitro models. However, there is a lack of research which focuses on formulating M.oleifera into a functional wound dressing. In this study, the M.oleifera leaf standardized aqueous extract with highest potency in vitro migration was formulated into a film for wound healing application. Firstly, M. oleifera leaf were extracted in various solvents (aqueous, 50%, 70% and 100% ethanolic extracts) and standardized by reference standards using UHPLC technique. The extracts were then tested for cell migration and proliferation using HDF and HEK cell lines. M. oleifera leaf aqueous extract was then incorporated into alginate-pectin (SA-PC) based film dressing. The film dressings were characterized for the physicochemical properties and the bioactives release from the M. oleifera leaf extract loaded film dressing was also investigated using Franz diffusion cells. All extracts were found to contain vicenin-2, chlorogenic acid, gallic acid, quercetin, kaempferol, rosmarinic acid and rutin. Among all M. oleifera extracts, aqueous standardized leaf extracts showed the highest human dermal fibroblast and human keratinocytes cells proliferation and migration properties. Among the film formulations, SA-PC (3% w/v) composite film dressing containing M. oleifera aqueous leaf extract was found to possess optimal physicochemical properties as wound dressing. A potentially applicable wound dressing formulated as an alginate-pectin film containing aqueous extracts of M. oleifera has been developed. The dressing would be suitable for wounds with moderate exudates. Copyright © 2017 Elsevier B.V. All rights reserved.

    Bleeding episodes in patients with congenital or acquired bleeding disorders are usually managed with factor concentrates or blood products. However, external and accessible bleeds may effectively be managed with topical hemostasis. After the application of the Hemcon, a Food and Drug Administration-approved chitosan-based hemostatic dressing was used as the "last resort" to successfully control external bleeds in 2 patients with severe bleeding disorders. We describe a single-center experience with this dressing, including its use in pediatric patients as the first mode of therapy. A total of 5 patients (median age 2 y) with severe bleeding disorders were treated with topical chitosan-based dressing for a total of 6 bleeding episodes. The dressing was used either after the failure of extensive systemic therapy or as the first choice of treatment. In 4 of the 6 episodes, bleeding ceased immediately alleviating the need for systemic therapy. There was no rebleeding after the removal of the dressing and no adverse events or local skin reactions were recorded. Hemostatic dressings, such as the chitosan, should be encouraged for the treatment of external/accessible bleeds, especially among the pediatric patients with bleeding tendency.

    Modern wound dressings combine medical textiles with active compounds that stimulate wound healing while protecting against infection. Electrospun wound dressings have been extensively studied and the electrospinning technique recognized as an efficient approach for the production of nanoscale fibrous mats. The unique diverse function and architecture of antimicrobial peptides (AMPs) has attracted considerable attention as a tool for the design of new anti-infective drugs. Functionalizing electrospun wound dressings with these AMPs is nowadays being researched. In the present work, we explore these new systems by highlighting the most important characteristics of electropsun wound dressings, revealing the importance of AMPs to wound healing, and the methods available to functionalize the electrospun mats with these molecules. The combined therapeutic potential of collagen type I and these AMP functionalized dressings will be highlighted as well; the significance of these new strategies for the future of wound healing will be clarified.

  13. A simplified model for TIG-dressing numerical simulation

    Irrespective of the mechanical properties of the alloy to be welded, the fatigue strength of welded joints is primarily controlled by the stress concentration associated with the weld toe or weld root. In order to reduce the effects of such notch defects in welds, which are influenced by tensile properties of the alloy, post-weld improvement techniques have been developed. The two most commonly used techniques are weld toe grinding and TIG dressing, which are intended to both remove toe defects such as non-metallic intrusions and to re-profile the weld toe region to give a lower stress concentration. In the case of TIG dressing the weld toe is re-melted to provide a smoother transition between the plate and the weld crown and to beneficially modify the residual stress redistribution. Assessing the changes to weld stress state arising from TIG-dressing is most easily accomplished through a complex numerical simulation that requires coupled thermo-fluid dynamics and solid mechanics. However, this can be expensive in terms of computational cost and time needed to reach a solution. The present paper therefore proposes a simplified numerical model that overcomes such drawbacks and which simulates the remelted toe region by means of the activation and deactivation of elements in the numerical model.

    Here, polaritons, mixed light-matter quasiparticles, undergo a transition to a condensed, macroscopically coherent state at low temperatures or high densities. Recent experiments show that coupling light to organic molecules inside a microcavity allows condensation at room temperature. The molecules act as saturable absorbers with transitions dressed by molecular vibrational modes. Motivated by this, we calculate the phase diagram and spectrum of a modified Tavis-Cummings model, describing vibrationally dressed two-level systems, coupled to a cavity mode. Coupling to vibrational modes can induce re-entrance, i.e. a normal-condensed-normal sequence with decreasing temperature and can drive the transition first-order.

    2016-09-01

    The current study examined the relevance of familial environment (negative maternal messages) to the phenomenon of maladaptive (obligatory) exercise, defined as exercise fixation. Weight/shape concerns and exercise frequency were examined as potential mediators, evaluated both with and without eating disorder symptoms as a covariate. Self-report data comprising sociodemographic details and measures of parental weight messages, body image, obligatory exercise, and disordered eating symptoms were completed by 298 young female attendees of health and fitness centres. The frequency of negative maternal messages demonstrated significant associations with all of weight/shape concerns, exercise frequency, exercise fixation, and eating disorder symptoms. In the initial model, partial mediation of maternal messages to exercise fixation was evident as negative maternal messages continued to have a direct effect on exercise fixation. In the second model, with the inclusion of eating disorder symptoms as a covariate, this direct effect was maintained while mediation was no longer evident. The data provide further support for the association between disordered eating symptoms and maladaptive exercise, as defined by exercise fixation. Nevertheless, the importance of negative maternal messages as a key environmental enabler of exercise fixation has been demonstrated, even after the effects of weight/shape concerns and exercise frequency were accounted for. Clinically, addressing weight-related talk in the family home may reduce the incidence of problematic cognitions and behaviours associated with both maladaptive exercise and disordered eating symptoms.

    Honey is known, since antiquity, as an effective wound dressing. Emergence of resistant strains and the financial burden of modern dressings, have revived honey as cost-effective dressing particularly in developing countries. Its suitability for all stages of wound healing suggests its clinical effectiveness in diabetic foot wound infections. Thirty infected diabetic foot wounds were randomly selected from patients presenting to Surgery Department, Suez Canal University Hospital, Ismailia, Egypt. Honey dressing was applied to wounds for 3 months till healing, grafting or failure of treatment. Changes in grade and stage of wounds, using University of Texas Diabetic Wound Classification, as well as surface area were recorded weekly. Bacterial load was determined before and after honey dressing. Complete healing was significantly achieved in 43.3% of ulcers. Decrease in size and healthy granulation was significantly observed in another 43.3% of patients. Bacterial load of all ulcers was significantly reduced after the first week of honey dressing. Failure of treatment was observed in 6.7% of ulcers. This study proves that commercial clover honey is a clinical and cost-effective dressing for diabetic wound in developing countries. It is omnipresence and concordance with cultural beliefs makes it a typical environmentally based method for treating these conditions. Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.

    2017-06-28

    While Manuka honey in vitro is strongly antimicrobial, there have been, to the best of the authors' knowledge, no studies showing that dressings impregnated with Manuka honey can kill organisms in the dressing itself. The investigators used the American Association of Textile Chemists and Colorists' 100 test methodology to compare honey-impregnated dressings with control dressings (without honey) on the ability to kill common wound pathogens. Organisms were chosen after a review of the causal organisms found in actual wound infections over a 12-month period in a busy outpatient wound clinic. Even when the dressings were challenged daily with further inoculated organisms, > 5-log reductions were routinely noted across a range of pathogens, including multiple drug-resistant species using dressings containing Manuka honey relative to the control. The results presented herein show that when well-characterized medical-grade Manuka honey is used in dressings (ie, a minimum of 400 mg methylglyoxal/kg) these dressings can comprehensively kill common wound pathogens associated with infected wounds.

    Honey is one of the oldest substances used in wound management. Efficacy of Gelam honey in wound healing was evaluated in this paper. Sprague-Dawley rats were randomly divided into four groups of 24 rats each (untreated group, saline group, Intrasite Gel group, and Gelam honey group) with 2 cm by 2 cm full thickness, excisional wound created on neck area. Wounds were dressed topically according to groups. Rats were sacrificed on days 1, 5, 10, and 15 of treatments. Wounds were then processed for macroscopic and histological observations. Gelam-honey-dressed wounds healed earlier (day 13) than untreated and saline treated groups, as did wounds treated with Intrasite Gel. Honey-treated wounds exhibited less scab and only thin scar formations. Histological features demonstrated positive effects of Gelam honey on the wounds. This paper showed that Gelam honey dressing on excisional wound accelerated the process of wound healing. PMID:22536292

    Previous reports indicated that various dysfunctions caused by stroke affect the level of independence in dressing. These dysfunctions can be hierarchical, and these effects on dressing performance can be complicated in stroke patients. However, there are no published reports focusing on the hierarchical structure of the relationships between the activities of daily living and balance function, motor and sensory functions of the affected lower limb, strength of the abdominal muscles and knee extension on the unaffected side, and visuospatial deficits. The purpose of this study was to elucidate the hierarchical and causal relationships between dressing performance and these dysfunctions in stroke patients. This retrospective study included 104 first-time stroke patients. The causal relationship between the dressing performance and age, time post stroke, balance function, motor and sensory functions of the affected lower limb, strength of the abdominal muscles and knee extension on the unaffected side, and visuospatial deficits were examined using path analysis. A hypothetical path model was created based on previous studies, and the goodness of fit between the data and model were verified. A modified path model was created that achieved an almost perfect fit to the data. Balance function and abdominal muscle strength have direct effects on dressing performance, with standardized direct effect estimates of 0.78 and 0.15, respectively. Age, motor and sensory functions of the affected lower limb, and strength of abdominal muscle and knee extension on the unaffected side have indirect effects on dressing by influencing balance function. Our results suggest that dressing performance depends strongly on balance function, and it is mainly influenced by the motor function of the affected lower limb.

    Central venous access device (CVAD) associated complications are a preventable source of patient harm, frequently resulting in morbidity and delays to vital treatment. Dressing and securement products are used to prevent infectious and mechanical complications, however current complication rates suggest customary practices are inadequate. The aim of this study was to evaluate the feasibility of launching a full-scale randomized controlled efficacy trial of innovative dressing and securement products for pediatric tunneled CVAD to prevent complication and failure. An external, pilot, four-group randomized controlled trial of standard care (bordered polyurethane dressing and suture), in comparison to integrated securement-dressing, suture-less securement device, and tissue adhesive was undertaken across two large, tertiary referral pediatric hospitals in Australia. Forty-eight pediatric participants with newly inserted tunneled CVADs were consecutively recruited. The primary outcome of study feasibility was established by elements of eligibility, recruitment, attrition, protocol adherence, missing data, parent and healthcare staff satisfaction and acceptability, and effect size estimates for CVAD failure (cessation of function prior to completion of treatment) and complication (associated bloodstream infection, thrombosis, breakage, dislodgement or occlusion). Dressing integrity, product costs and site complications were also examined. Protocol feasibility was established. CVAD failure was: 17% (2/12) integrated securement-dressing; 8% (1/13) suture-less securement device; 0% tissue adhesive (0/12); and, 0% standard care (0/11). CVAD complications were: 15% (2/13) suture-less securement device (CVAD associated bloodstream infection, and occlusion and partial dislodgement); 8% (1/12) integrated securement-dressing (partial dislodgement); 0% tissue adhesive (0/12); and, 0% standard care (0/11).

    To identify individual therapist behaviors which elicit client change talk or sustain talk in motivational interviewing sessions. Motivational interviewing sessions from a single-session alcohol intervention delivered to college students were audio-taped, transcribed, and coded using the Motivational Interviewing Skill Code (MISC), a therapy process coding system. Participants included 92 college students and eight therapists who provided their treatment. The MISC was used to code 17 therapist behaviors related to the use of motivational interviewing, and client language reflecting movement toward behavior change (change talk), away from behavior change (sustain talk), or unrelated to the target behavior (follow/neutral). Client change talk was significantly more likely to immediately follow individual therapist behaviors [affirm (p=.013), open question (p<.001), simple reflection (p<.001), and complex reflection (p<.001)], but significantly less likely to immediately follow others (giving information (p<.001) and closed question (p<.001)]. Sustain talk was significantly more likely to follow therapist use of open questions (p<.001), simple reflections (p<.001), and complex reflections (p<.001), and significantly less likely to occur following therapist use of therapist affirm (p=.012), giving information (p<.001), and closed questions (p<.001). Certain individual therapist behaviors within motivational interviewing can either elicit both client change talk and sustain talk or suppress both types of client language. Affirm was the only therapist behavior that both increased change talk and also reduced sustain talk. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study was designed to evaluate the antibacterial activity of a wound dressing which combines polyacrylate fibres and a silver lipido-colloid matrix (UrgoClean Ag, silver polyabsorbent dressing), against biofilm of methicillin-resistant Staphylococcus aureus (MRSA). Samples of silver polyabsorbent dressing and the neutral form of this dressing (UrgoClean) were applied to biofilms of MRSA formed on a collagen I-coated surface, cultured for 24 hours. Different exposure times were tested (1, 2, 4 and 7 days) without dressing change. The biofilm reduction was quantified by using culture methods and by confocal laser scanning microscopy experiments. The application of the silver polyabsorbent dressing resulted in a significant decrease of the biofilm population by a log reduction of 4.6, after 24 hours of exposure. Moreover, the antibiofilm activity was maintained for 7 days with reduction values up to 4 log (reduction of biofilm superior to 99.99%). The application of the neutral dressing also induced a significant reduction of the concentration of sessile cells after 1 day (about 0.90 log). The results obtained with this neutral form of the dressing showed that the polyacrylate fibres were able to exert a mechanical disruption of the biofilm architecture. These in vitro experiments demonstrated that silver polyabsorbent dressing was able to strongly reduce the biofilm of MRSA. The antibiofilm mechanism of this dressing can be explained by a dual action of the polyabsorbent fibres (based on ammonium polyacrylate polymer around an acrylic core) which induced a mechanical disruption of the biofilm matrix and/or a sequestration of sessile cells, and the diffusion of silver ions which produced bactericidal activity. This study was supported by Laboratoires Urgo (Dijon). P. Janod is an employee of Laboratoires Urgo. The company had no influence on the experimental design and the interpretation of the results.

    Despite extensive research into the treatment of partial-thickness burns, to date there has not been the emergence of a preeminent modality. This pilot study, the first such study to be performed in a burn unit in the US, was designed to evaluate the efficacy and outcomes of the application of copolymer dressing (Suprathel; PolyMedics Innovations Corporation, Stuttgart, Germany) for both superficial and deeper partial-thickness burns. The copolymer dressing was used as a primary wound dressing to treat superficial and deep partial-thickness burns (average 5% total body surface area) in paediatric patients. Burns were debrided within 24 hours, at bedside, in the burn unit or in the operating room. The copolymer dressing was then applied directly to the wound and covered with a non-adherent second layer and an absorptive outer dressing. After discharge, patients were seen every 5-7 days until healed. Parameters evaluated included average hospital length of stay, average number of intravenous doses of narcotics administered, pain score at first follow-up visit, average time to complete re epithelialisation, incidence of burn wound infection, and patient/parent satisfaction on a 4-point scale. We also evaluated our experience with the dressing. Data were evaluated retrospectively under an Investigational Review Board approved protocol. Of the 17 patients assessed the average hospital length of stay was 1.4 days during which the average number of intravenous narcotic doses administered before copolymer dressing application was 1.5 and after was 0.1 doses. At the first follow-up visit, average pain score was 1.2 on a 10-point scale and the average time to re epithelialisation was 9.5 days. There was no incidence of burn wound infection. Patient/parent satisfaction was average of 3.66 on a 4-point scale. The staff had found that the self-adherence and elasticity of the dressing made it easy to apply and stay adherent, especially in areas of difficult contour. There were

    Approximately 70% of all people with severe burns die from related infections despite advances in treatment regimens and the best efforts of nurses and doctors. Silver ion-eluting wound dressings are available for overcoming this problem. However, there are reports of deleterious effects of such dressings due to cellular toxicity that delays the healing process, and the dressing changes needed 1-2 times a day are uncomfortable for the patient and time consuming for the stuff. An alternative concept in wound dressing design that combines the advantages of occlusive dressings with biodegradability and intrinsic topical antibiotic treatment is described herewith. The new composite structure presented in this article is based on a polyglyconate mesh and a porous poly-(dl-lactic-co-glycolic acid) matrix loaded with gentamicin developed to provide controlled release of antibiotics for three weeks. In vivo evaluation of the dressing material in contaminated deep second degree burn wounds in guinea pigs (n=20) demonstrated its ability to accelerate epithelialization by 40% compared to an unloaded format of the material and a conventional dressing material. Wound contraction was reduced significantly, and a better quality scar tissue was formed. The current dressing material exhibits promising results, does not require frequent bandage changes, and offers a potentially valuable and economic approach to treating the life-threatening complication of burn-related infections.

    2013-01-01

    Background In the paediatric population, pain and distress associated with burn injuries during wound care procedures remain a constant challenge. Although silver dressings are the gold standard for burn care in Australasia, very few high-level trials have been conducted that compare silver dressings to determine which will provide the best level of care clinically. Therefore, for paediatric patients in particular, identifying silver dressings that are associated with lower levels of pain and rapid wound re-epithelialisation is imperative. This study will determine whether there is a difference in time to re-epithelialisation and pain and distress experienced during wound care procedures among Acticoat™, Acticoat™ combined with Mepitel™ and Mepilex Ag™ dressings for acute, paediatric partial thickness burns. Methods/Design Children aged 0 to 15 years with an acute partial thickness (superficial partial to deep partial thickness inclusive) burn injury and a burn total body surface area of ≤10% will be eligible for the trial. Patients will be randomised to one of the three dressing groups: (1) Acticoat™ or (2) Acticoat™ combined with Mepitel™ or (3) Mepilex Ag™. A minimum of 28 participants will be recruited for each treatment group. Primary measures of pain, distress and healing will be repeated at each dressing change until complete wound re-epithelialisation occurs or skin grafting is required. Additional data collected will include infection status at each dressing change, physical function, scar outcome and scar management requirements, cost effectiveness of each dressing and staff perspectives of the dressings.

    To demonstrate the efficacy of a highly hydrophilic polyurethane foam dressing in the treatment of diabetic ulcers. Diabetic foot ulcers often pose a difficult treatment problem. Polyurethane foam dressings have been used worldwide to accelerate wound healing, but only a few clinical studies demonstrate the effect of foam dressing on the healing of diabetic ulcers. Medical records of 1342 patients with diabetic ulcers who were admitted and treated at the authors' institution were reviewed. A total of 208 patients met the study's inclusion criteria. Of these 208 patients, 137 were treated with a highly hydrophilic polyurethane foam dressing, and 71 were treated with saline gauze (control group). Except for the application of polyurethane foam dressing, the treatment method was identical for patients in both groups. The wound healing outcomes of the 2 groups were compared. Complete wound healing occurred in 87 patients (63.5%) in the polyurethane foam dressing group and in 28 patients (39.4%) in the control group within 12 weeks (P < .05, X test). The mean percentage of wound area reduction in both groups was statistically significant (P < .05, Mann-Whitney U test). The mean time required for complete closure in patients who achieved complete healing within 12 weeks was 6.2 (SD, 3.4) weeks and 7.3 (SD, 2.6) weeks in the polyurethane foam dressing and control groups, respectively (P < .05, Mann-Whitney U test). These results indicate that the highly hydrophilic polyurethane foam dressing may provide an effective treatment strategy for diabetic foot ulcers.

    Acrylates and methacrylates are acrylic resin monomers that are known to induce skin sensitization as a result of their presence in different materials, such as nail cosmetics, dental materials, printing inks, and adhesives. Allergic contact dermatitis resulting from the use of modern wound dressings containing them has only rarely been reported. To describe 2 patients who developed allergic contact dermatitis caused by acrylic-based modern medical dressings and/or adhesives. The medical charts of patients observed since 1990 were retrospectively reviewed for (meth)acrylate allergy resulting from contact with such materials, and their demographic characteristics and patch test results were analysed. Two patients were observed in 2014 and 2016 who had presented with positive patch test reactions to several acrylic-based dressings and/or adhesive materials, and to several (meth)acrylates, that is, hydroxyethyl acrylate, hydroxyethyl methacrylate, ethyleneglycol dimethacrylate, bisphenol A-glycidyl methacrylate/epoxy-acrylate, urethane diacrylate, and/or penta-erythritol acrylate. Allergic contact dermatitis needs to be considered in patients with eczematous reactions or delayed healing following the use of acrylic-based modern dressings or adhesives. However, identification of the culprit allergen is hampered by poor cooperation from the producers, so adequate labelling of medical devices is an urgent necessity. © 2018 John Wiley & Sons A/S.

    To examine the efficacy of the folk remedy of chicken-egg membrane dressing on wound healing. Full-thickness excisional wounds were created on 14 male Sprague-Dawley rats in 2 separate trials. Each animal received 2 wounds on the upper back. One wound was untreated, and the other was dressed with chicken-egg membrane to assess its impact on wound healing. Half of the rats received egg membrane treatment on the inferior wound, whereas the other half received egg membrane treatment on the superior wound. Membrane replacement, wound debridement, and imaging were done on days 5, 8, and 10 and then imaging continued on days 12, 14, 16, 18, and 20 of the experiment. Healing rate was measured based on the wound area over the 20 days of the experiment. The wounds dressed with chicken-egg membrane had a significantly (P < .01) faster rate of healing compared with the control at the early stages of healing between days 0 and 5. This group healed 21% faster during this early phase, compared with the control group. Overall, however, wound healing rates were indistinguishable from days 5 to 20. Chicken-egg membrane dressing significantly improves healing of cutaneous wounds in the early stages of wound healing.

    Compression dressing has been assumed effective, but never formally examined in the field. A prospective interventional trial examined efficacy and feasibility of an elastic adhesive dressing compression device in the arena of the traumatic incident. The primary variable examined was the bleeding rate from wounds compared before and after dressing. Sixty-two consecutive bleeding wounds resulting from penetrating trauma were treated. Bleeding intensity was profuse in 58%, moderate 23%, and mild in 19%. Full control of bleeding was achieved in 87%, a significantly diminished rate in 11%, and, in 1 case, the technique had no influence on the bleeding rate. The Wilcoxon test for variables comparing bleeding rates before and after the procedure obtained significant difference (Z = -6.9, p < 0.01). No significant complications were observed. Caregivers were highly satisfied in 90% of cases. Elastic adhesive dressing was observed as an effective and reliable technique, demonstrating a high rate of success without complications.

    To compare infection rates associated with 2 dressing solutions for metal-skin interfaces. 60 patients who underwent distraction osteogenesis with external fixators were equally randomised into 2 dressing solution groups (diluted povidone-iodine vs. saline). Fixations were attained using either rigid stainless steel 5-mm diameter half pins or smooth stainless steel 1.8-mm diameter wires. Half-pin fixation had one metal-skin interface, whereas wire fixation had 2 interfaces. Patients were followed up every 2 weeks for 6 months. Of all 788 metal-skin interfaces, 143 (18%) were infected: 72 (19%) of 371 in the diluted povidone-iodine group and 71 (17%) of 417 in the saline group. Dressing solution and patient age did not significantly affect infection rates. Half-pin fixation was more likely to become infected than wire fixation (25% vs 15%). Saline is as effective as diluted povidone-iodine as a dressing solution for metal-skin interfaces of external fixators. Saline is recommended in view of its easy availability and lower costs.

    The life-threatening drug rash with eosinophilia and systemic symptoms (DRESS) syndrome occurs most commonly after exposure to drugs, clinical features mimic those found with other serious systemic disorders. It is rarely associated with thrombotic microangiopathy. We describe the unique case of a 44-year-old man who simultaneously experienced DRESS syndrome with thrombotic microangiopathy (TMA) after a 5 days treatment with fluindione. Clinical evaluation leads to the discovery of an underlying lymphangiomatosis, due to a Noonan syndrome. The anticoagulant was withdrawn, and corticosteroids (1 mg/kg/day) and acenocoumarol were started. Clinical improvement ensued. At follow-up the patient is well. The association of DRESS with TMA is a rare condition; we believe that the presence of the underlying Noonan syndrome could have been the trigger. Moreover, we speculate about the potential interrelations between these entities.

    The aim of the study was to develop an antimicrobial hydrogel wound dressing by means of radiation-initiated crosslinking of hydrophilic polymers, i.e. by well-established technology comprising gel manufacturing and its sterilization in one process. The approach included admixture of chitosan of relatively low molecular weight dissolved in lactic acid (LA) into the initial regular components of the conventional hydrogel dressing based on poly(N-vinyl pyrrolidone) (PVP) and agar. Molecular weight of chitosan was regulated by radiation-initiated degradation in the range of 39-132 kg mol-1. Optimum total concentration of LA in the resultant hydrogel dressing was evaluated as 0.05 mol dm-3, that is ca. 0.5%. Presence of LA in the system influenced essential radiation and technological parameters of hydrogel manufacturing. The setting temperature of the pre-hydrogel mixture, resulting from agar ability to congeal, was reduced with LA concentration, yet remained significantly above the room temperature. 0.5% of chitosan was effectively dissolved in aqueous solution of lactic acid due to its pH (lower than 5.5). Radiation parameters of PVP crosslinking in the presence of LA, as determined with generalized Charlesby-Pinner equation, were reflected in slight reduction of the maximum gel fraction and increase in gelation dose and in the factor comparing yields of scission to crosslinking. Nevertheless, essentially physical characteristics of the hydrogel was not affected, except for somewhat increased water uptake capacity, what in turn improves functionality of the dressing as extensive exudate for the wound can be efficiently absorbed. Preliminary microbiological studies showed antimicrobial character of the chitosan-containing hydrogel towards Gram-positive bacterial strain.

  15. Positive and negative eating expectancies in disordered eating among women and men.

    Deficits in emotion regulation are known to characterize disordered eating patterns including binge eating, purging, and dietary restraint, though much of this work has been conducted exclusively on women. Eating expectancies, or expectations regarding reinforcement from food and eating, constitute one cognitive mechanism that is thought to serve as a proximal influence on eating behavior. Previous research shows that eating to manage negative affect (a negative eating expectancy) is associated with eating pathology in women, but less is known about eating as a reward or for pleasure (a positive eating expectancy). In addition, no prior work has examined eating expectancies among men. This study examines the role of emotion regulation and eating expectancies on disordered eating in women and men. Participants were 121 female and 80 male undergraduates who completed self-report measures of emotion regulation, eating expectancies, and disordered eating. In women, body mass index (BMI), emotion regulation, and eating to manage negative affect directly predicted disordered eating in the final multivariate model, whereas eating for pleasure or reward was inversely associated with disordered eating. However, in men, emotion regulation predicted disordered eating, but not when eating expectancies were added to the model. In the final model, only BMI and eating to manage negative affect contributed significantly to the variance in disordered eating. These findings suggest that some correlates of eating pathology, particularly eating expectancies, may vary by gender. Future research should continue to examine gender differences in the explanatory mechanisms underlying disordered eating. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-07-01

    The purpose of this study was to examine the mediating effect of anxiety in the relationship between anticipation and pain in people with chronic wounds. Pain is common in people with chronic wounds. Anticipation or negative expectation of discomfort has been shown to have an augmenting effect on pain; also known as nocebo hyperalgesia. This was a cross-sectional study with repeated measures. Prior to dressing change, anticipatory pain level was evaluated by a 11-point numerical rating scale and anxiety by the Six-items State-Trait Anxiety Inventory (STAI-6). During wound dressing changes, pain was measured before dressing removal, at dressing removal, at cleansing and dressing application using the numerical scale. Analysis was completed based on the data from a convenience sample of 96 patients. Participants reported more pain at cleansing and dressing removal than baseline. High levels of anticipation, anxiety and pain at dressing change for wounds were related to heavy exudate and wound that were covered with necrotic tissue. Finally, the relationship between anticipation and pain perception was mediated by anxiety. Anticipation of pain triggers anxiety that can lead to increased pain. There is a need to incorporate evaluation of anxiety and personal expectations as part of comprehensive pain assessment. Clinicians should be aware of the impact of emotions and anticipation on overall pain experience. © 2015 John Wiley & Sons Ltd.

    We have conducted a basic study on the influences on ultrasonic properties when LIPUS is applied through wound dressing. According to the results of ex vivo experiments conducted to date, LIPUS showed ultrasonic properties such as transmittance, coefficient of transmission, and a non-uniformity ratio through film wound dressing better than other wound dressing, and it was considered that LIPUS's effect for fracture healing was not influenced by film wound dressing. Then, we discussed the influence on the effect of LIPUS through film wound dressing. Thirty male 8-week-old Sprague-Dawley rats were used for the trial. After creating close transverse femoral fractures on the right legs of these 30 rats, they were divided into 3 groups of 10; LIPUS through wound dressing (Group A), LIPUS without wound dressing (Group B), and No LIPUS treatment (Group C). OPSITE Wound, which was thought to have the least influence on ultrasound properties, was used for this trial. Group A and B received LIPUS for 20 minutes a day from the first day after the fractures. LIPUS was generated from Teijin Pharma's device for a basic experiment. When treating Group A, the wound dressing was pasted on the ultrasound terminal in order to apply LIPUS through the dressing. We assessed the time-oriented morphological change of each group in anesthetized condition using simple radiographs on the 8th, 16th, and 24th day after the fractures. Six rats in Group A, 2 in Group B, and 1 in Group C died in anesthesia, and we discussed the remaining 4 rats in Group A, 8 in Group B, and 9 in Group C. We defined more than one teleost callus bridging as bone-union. We also counted a bone remodeling when we recognized the absorption of existing cortical bone and the transformation of new bone to cortical bone in simple radiographs. As a result, compared with Group C, we recognized that both bone union and remodeling accelerated remarkably in Group B, but not in Group A. It suggested that LIPUS through wound

    Seed dressing with pesticides is widely used to protect crop seeds from pest insects and fungal diseases. While there is mounting evidence that especially neonicotinoid seed dressings detrimentally affect insect pollinators, surprisingly little is known on potential side effects on soil biota. We hypothesized that soil organisms would be particularly susceptible to pesticide seed dressings as they get in direct contact with these chemicals. Using microcosms with field soil we investigated, whether seeds treated either with neonicotinoid insecticides or fungicides influence the activity and interaction of earthworms, collembola, protozoa and microorganisms. The full-factorial design consisted of the factor Seed dressing (control vs. insecticide vs. fungicide), Earthworm (no earthworms vs. addition Lumbricus terrestris L.) and collembola (no collembola vs. addition Sinella curviseta Brook). We used commercially available wheat seed material (Triticum aesticum L. cf. Lukullus) at a recommended seeding density of 367 m(-2). Seed dressings (particularly fungicides) increased collembola surface activity, increased the number of protozoa and reduced plant decomposition rate but did not affect earthworm activity. Seed dressings had no influence on wheat growth. Earthworms interactively affected the influence of seed dressings on collembola activity, whereas collembola increased earthworm surface activity but reduced soil basal respiration. Earthworms also decreased wheat growth, reduced soil basal respiration and microbial biomass but increased soil water content and electrical conductivity. The reported non-target effects of seed dressings and their interactions with soil organisms are remarkable because they were observed after a one-time application of only 18 pesticide treated seeds per experimental pot. Because of the increasing use of seed dressing in agriculture and the fundamental role of soil organisms in agroecosystems these ecological interactions should

  20. On talking-as-dreaming.

    PubMed

    Ogden, Thomas H

    2007-06-01

    Many patients are unable to engage in waking-dreaming in the analytic setting in the form of free association or in any other form. The author has found that "talking-as-dreaming" has served as a form of waking-dreaming in which such patients have been able to begin to dream formerly undreamable experience. Such talking is a loosely structured form of conversation between patient and analyst that is often marked by primary process thinking and apparent non sequiturs. Talking-as-dreaming superficially appears to be "unanalytic" in that it may seem to consist "merely" of talking about such topics as books, films, etymology, baseball, the taste of chocolate, the structure of light, and so on. When an analysis is "a going concern," talking-as-dreaming moves unobtrusively into and out of talking about dreaming. The author provides two detailed clinical examples of analytic work with patients who had very little capacity to dream in the analytic setting. In the first clinical example, talking-as-dreaming served as a form of thinking and relating in which the patient was able for the first time to dream her own (and, in a sense, her father's) formerly unthinkable, undreamable experience. The second clinical example involves the use of talking-as-dreaming as an emotional experience in which the formerly "invisible" patient was able to begin to dream himself into existence. The analyst, while engaging with a patient in talking-as-dreaming, must remain keenly aware that it is critical that the difference in roles of patient and analyst be a continuously felt presence; that the therapeutic goals of analysis be firmly held in mind; and that the patient be given the opportunity to dream himself into existence (as opposed to being dreamt up by the analyst).

    Many polymers and composites have been used to prepare active wound dressings. These materials have typically exhibited potentially toxic burst release of the drugs within the first few hours followed by a much slower, potentially ineffective drug release rate thereafter. Many of these materials also degraded to produce inflammatory and cytotoxic products. To overcome these limitations, composite active wound dressings were prepared here from two fully biodegradable and tissue compatible components, silicon oxide sol-gel (xerogel) microparticles that were embedded in tyrosine-poly(ethylene glycol)-derived poly(ether carbonate) copolymer matrices. Sustained, controlled release of drugs from these composites was demonstrated in vitro using bupivacaine and mepivacaine, two water-soluble local anesthetics commonly used in clinical applications. By systematically varying independent compositional parameters of the composites, including the hydrophilic:hydrophobic balance of the tyrosine-derived monomers and poly(ethylene glycol) in the copolymers and the porosity, weight ratio and drug content of the xerogels, drug release kinetics approaching zero-order were obtained. Composites with xerogel mass fractions up to 75% and drug payloads as high as 13% by weight in the final material were fabricated without compromising the physical integrity or the controlled release kinetics. The copolymer-xerogel composites thus provided a unique solution for the sustained delivery of therapeutic agents from tissue compatible wound dressings. 2010 Elsevier Ltd. All rights reserved.

    Binge-eating disorder (BED) as a distinct eating disorder category and night eating syndrome (NES) as a form of Other Specified Feeding or Eating Disorders were recently included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study sought to investigate the prevalence of BED and NES and associations with various forms of nonnormative eating behavior and psychopathology in prebariatric patients. Within a consecutive multicenter registry study, patients in 6 bariatric surgery centers in Germany were recruited. Overall, 233 prebariatric patients were assessed using the Eating Disorder Examination and self-report questionnaires. Assessment was unrelated to clinical procedures. Diagnostic criteria for full-syndrome BED and NES were currently met by 4.3% and 8.2% of prebariatric patients, respectively. In addition, 8.6% and 6.9% of patients met subsyndromal BED and NES criteria, respectively. Co-morbid BED and NES diagnoses were present in 3.9% of patients. In comparison to patients without any eating disorder symptoms, patients with BED and NES reported greater emotional eating, eating in the absence of hunger, and more symptoms of food addiction. Moreover, differences between patients with BED and NES emerged with more objective binge-eating episodes and higher levels of eating concern, weight concern, and global eating disorder psychopathology in patients with BED. BED and NES were shown to be prevalent among prebariatric patients, with some degree of overlap between diagnoses. Associations with nonnormative eating behavior and psychopathology point to their clinical significance and discriminant validity. Copyright © 2015 American Society for Bariatric Surgery.

    This study looks at six different modern wound dressings to investigate how likely they are to cause skin stripping and impairment of the skin's barrier function. Healthy volunteers had each dressing applied, removed and reapplied to the skin on their back over the study period of 15 days. Skin barrier function was investigated using the amount of transepidermal water loss (TEWL) and then related to the amount of skin stripping, investigated by measuring stained skin removal, the thickness of the stratum corneum after treatment, and the amount of skin attached to the removed dressings. General signs of trauma, such as skin dryness and erythema, were investigated by subjective and objective parameters. TEWL values measured on the untreated test area, as well as after application of Urgotul Trio, remained relatively unchanged and Mepilex Border decreased slightly (?1g/m2/h), while all other dressings displayed an increased in TEWL: Allevyn Adhesive (5g/m2/h), Versiva XC (14g/m2/h), Comfeel Plus (22g/m2/h) and Biatain (28g/m2/h). By the end of the study, only the untreated area (mean 43% dye remaining), Mepilex Border (76%) and Urgotul Trio (34%) areas had visible dye remaining. It is interesting to note that the untreated site had a colour change, suggesting loss of stratum corneum, due to the shedding of skin cells from the surface. The increase in total skin colour for Comfeel Plus and Biatain after day 8 might be assigned to an increased redness due to erythema. All the dressings showed evidence of stratum corneum attached to the adhesive, except Mepilex Border, which appeared to be free of any attached stratum corneum. Overall the best performance in terms of skin protection and failure to cause skin trauma was found to be for Mepilex Border. This project was funded by a grant from Mölnlycke Healthcare Ltd.

    This paper is a report of an evaluation of the effectiveness of a newly developed dressing for preventing persistent erythema and pressure ulcer development and improving the water-holding capacity without increasing the skin pH in bedridden older patients. Shear forces and skin dryness play important roles in persistent erythema and pressure ulcer development. To eliminate these risks, we developed a dressing to reduce shear forces and improve the water-holding capacity. However, the effects of this dressing in clinical settings remain unknown. An experimental bilateral comparison study was conducted at a hospital in Japan in 2004 with 37 bedridden older patients at risk of pressure ulcer development. The dressing was randomly applied to the right or left greater trochanter for 3 weeks. No dressing was applied to the opposite side as a control. The skin was monitored weekly during the 3-week application for persistent erythema and pressure ulcer development. Skin hydration and pH were also assessed during the intervention and for 1 week after dressing removal. The incidence of persistent erythema was significantly lower in the intervention area than the control area [P = 0.007, RR 0.18 (95% CI: 0.05-0.73) and NNT 4.11 (2.50-11.63) ]. No pressure ulcers occurred in either the intervention or control area. Skin hydration increased significantly during dressing application and remained high after removal (P < 0.001) relative to the control area. Skin pH decreased significantly during the application (P < 0.001) but returned to control levels after removal (P = 0.38). This safe and effective dressing can be used for patients with highly prominent bones and dry skin to prevent pressure ulcers.

    BACKGROUND: Eating disorders are becoming more apparent in primary care. Descriptions of character traits related to people with eating disorders are rarely reported in the primary care literature and there is little awareness of the implications of alexithymia--a concept that defines the inability to identify or express emotion. We hypothesised that many individuals with active eating disorders have alexithymic traits and a tendency to somatize their distress. AIM: To analyse the character traits and degree of alexithymia of a selected group of women with active eating disorders and in recovery, and to recommend responses by members of the primary care team that might meet the needs of such individuals. METHOD: Letters were sent to 200 female members of the Eating Disorders Association who had agreed to participate in research. Seventy-nine women volunteered to complete four postal questionnaires. This gave a response rate of 38.5%. Responders were categorised into three groups--anorexic, bulimic, and recovered--using the criteria of the Eating Disorders Inventory (EDI-2). The results of the 16PF5 Personality Inventory (16PF5) and the Toronto Alexithymia Scale (TAS-20) were analysed using one-way analysis of variance (ANOVA) and correlated using Pearson's correlation. A biographical questionnaire was also completed. RESULTS: In all three subgroups, high scores were achieved on the 16PF5 on 'apprehension and social sensitivity', while there were significant differences in the scores for 'privateness': a scale that measures the ability to talk about feelings and confide in others. On the TAS-20, 65% of the anorexic and 83% of the bulimic group scored in the alexithymic range compared with 33% of the recovered group. There was a significant negative correlation between alexithymia and social skills such as 'social and emotional expressivity' on the 16PF5. CONCLUSION: The results of this study emphasise the difference between those with active eating disorders who

    Reward mechanisms are likely implicated in the pathophysiology of binge-eating behaviour, which is a key symptom of binge-eating disorder (BED). Since endocannabinoids modulate food-related reward, we aimed to investigate the responses of anandamide (AEA) and 2-arachidonoylglycerol (2-AG) to hedonic eating in patients with BED. Peripheral levels of AEA and 2-AG were measured in 7 obese BED patients before and after eating favorite (hedonic eating) and non-favorite (non-hedonic eating) foods. We found that plasma levels of AEA progressively decreased after eating the non-favorite food and significantly increased after eating the favorite food, whereas plasma levels of 2-AG did not differ significantly between the two test conditions, although they showed a trend toward significantly different time patterns. The changes in peripheral AEA levels were positively correlated to the subjects’ sensations of the urge to eat and the pleasantness while eating the presented food, while changes in peripheral 2-AG levels were positively correlated to the subjects’ sensation of the pleasantness while eating the presented food and to the amount of food they would eat. These results suggest the occurrence of distinctive responses of endocannabinoids to food-related reward in BED. The relevance of such findings to the pathophysiology of BED remains to be elucidated.

    Despite the recent improvements in cell culture and dermal regeneration methods, tissue engineering of skin has yet to receive widespread acceptance in the management of burn injuries. The reasons for this are complex and include not only the inherent costs of (particularly) setting up and running such a system but also the continuing difficulties in achieving successful engraftment of the neoepidermis. The latter has previously been addressed in a number of ways, including improving the recipient bed and using pre-confluent delivery systems to allow earlier application of cells to that wound bed. One area that has received little attention is that of the optimal wound dressing to use with this technology; the cells are very poorly attached at early time points, and, in this context, the traditional dressing of paraffin gauze has never been formally assessed in comparison with newer materials. Using a porcine acute wound chamber model, we performed a prospective randomised trial to assess four different wound dressings with reference to the amount of epidermal cover gained and the histological quality of the regenerated skin after 3 weeks. Out of the four materials tested, polyurethane foam (Allevyn) was superior histologically (although equal in take rate with paraffin gauze), whilst polythene sheet (Opsite) and silicone sheet were substantially inferior. We conclude that the traditional dressing used with this technology should be compared with polyurethane foam in a clinical trial. In the future, novel dressings should be formally tested against traditional methods before being adopted. Copyright 2001 The British Association of Plastic Surgeons.

  9. Protease Inhibition by Oleic Acid Transfer From Chronic Wound Dressings to Albumin

    High elastase and cathepsin G activities have been observed in chronic wounds. These levels can inhibit healing through degradation of growth factors, cytokines, and extracellular matrix proteins. Oleic acid (18:1) is a non-toxic elastase inhibitor with some potential for redressing the imbalance of elastase activity found in chronic wounds. Cotton wound dressing material was characterized as a transfer carrier for affinity uptake of 18:1 by albumin under conditions mimicking chronic wounds. 18:1-treated cotton was examined for its ability to bind and release the fatty acid in the presence of albumin. The mechanism of 18:1 uptake from cotton and binding bymore » albumin was examined with both intact dressings and cotton fiber-designed chromatography. Raman spectra of the albumin-18:1 complexes under liquid-liquid equilibrium conditions revealed fully saturated albumin-18:1 complexes with a 1:1 weight ratio of albumin:18:1. Cotton chromatography under liquid-solid equilibrium conditions revealed oleic acid transfer from cotton to albumin at 27 mole equivalents of 18:1 per mole albumin. Cotton was contrasted with hydrogel, and hydrocolloid wound dressing for its comparative ability to lower elastase activity. Each dressing material evaluated was found to release 18:1 in the presence of albumin with significant inhibition of elastase activity. The 18:1-formulated wound dressings lowered elastase activity in a dose dependent manner in the order cotton gauze > hydrogel > hydrocolloid. In contrast the cationic serine protease Cathepsin G was inihibited by 18:1 within a narrow range of 18:1-cotton formulations. Four per cent Albumin solutions were most effective in binding cotton bound-18:1. However, 2% albumin was sufficient to transfer quantities of 18:1 necessary to achieve a significant elastase-lowering effect. Formulations with 128 mg 18:1/g cotton gauze had equivalent elastase lowering with 1 - 4% albumin. 18:1 bound to cotton wound dressings may have promise in

    Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare, severe and potentially fatal cutaneous adverse drug reaction (the mortality rate is up to 10 %) associated with numerous and apparently heterogeneous drugs. The aetiology is unknown. To report Italian cases of DRESS over a 10-year period. We searched the National Pharmacovigilance Network (NPN) for the term 'drug reaction with eosinophilia and systemic symptoms' from 1 January 2004 to 1 January 2014, to identify all reports of DRESS. Each case was checked to avoid duplication. In the NPN, we identified 91 serious cases of DRESS: 68 were spontaneous, still-unpublished reports, while 23 additional cases were derived from screening of the scientific literature, performed by marketing authorization holders. Notably, the single common element linking all cases of DRESS was intake of a drug containing an aromatic ring. Thanks to the largest national DRESS case series ever reported, we were able to hypothesize, for the first time, that there is an association between use of drugs containing an aromatic ring in their chemical structure and DRESS. This might aid understanding of the aetiology of DRESS and facilitate diagnosis.

  11. Dressings and topical agents for arterial leg ulcers.

    2015-06-29

    It is estimated that people in industrialised countries have a 1% chance of suffering from a leg ulcer at some time in their life. The majority of leg ulcers are associated with circulation problems; poor blood return in the veins causes venous ulcers (around 70% of ulcers) and poor blood supply to the legs causes arterial ulcers (around 22% of ulcers). Treatment of arterial leg ulcers is directed towards correcting the poor arterial blood supply, for example by correcting arterial blockages (either surgically or pharmaceutically). If the blood supply has been restored, these arterial ulcers can heal following principles of good wound care. Dressings and topical agents make up a part of good wound care for arterial ulcers but there are many products available and it is unclear what impact these have on ulcer healing. This is an update of a review first published in 2003. To determine whether topical agents and wound dressings affect healing in arterial ulcers. To compare healing rates, patient-centred outcomes and costs between wound dressings and topical agents. For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched November 2014) and The Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library) (2014, Issue 10). Randomised controlled trials (RCTs), or controlled clinical trials (CCTs) evaluating dressings and topical agents in the treatment of arterial leg ulcers were eligible for inclusion. The participants had to have ulcers that were described as arterial, and the time to healing, proportion completely healed, or rate of reduction in ulcer area had to be reported. All wound dressings and topical agents were eligible for inclusion in this review. The two review authors independently extracted information on the participants' characteristics, the interventions, and outcomes using a standardised data extraction form.

    The purpose of this study was to investigate the influence of different hydrophilic polymers on the swelling, bioadhesion and mechanical strength of hydrocolloid wound dressings (HCDs) in order to provide an appropriate composition for a hydrocolloid wound dressing system. In this study, the HCDs were prepared with styrene-isoprene-styrene copolymer (SIS) and polyisobutylene (PIB) as the base using a hot melting method. Additionally, numerous SIS/PIB-based HCDs were prepared with six hydrophilic polymers, and their wound dressing properties were assessed. Finally, the wound healing efficacy of the selected formulations was compared to a commercial wound dressing. The swelling ratio, bioadhesive force and mechanical strengths of HCDs were increased in the order of sodium alginate>sodium CMC=poloxamer=HPMC>PVA=PVP, sodium alginate>sodium CMC=poloxamer>PVA>HPMC=PVP and sodium alginate≥PVA>PVP=HPMC=sodium CMC>poloxamer, respectively. Among the hydrophilic polymers tested, sodium alginate most enhanced the swelling capacity, bioadhesive force and mechanical strengths. Thus, the hydrophilic polymers played great role in the swelling, bioadhesion and mechanical strength of SIS/PIB-based HCDs. The HCD formulation composed of PIB, SIS, liquid paraffin and sodium alginate at the weight ratio of 20/25/12/43 gave better wound dressing properties and more excellent wound healing efficacy than the commercial wound dressing. Therefore, the novel HCD formulation could be a promising hydrocolloid system for wound dressings. Copyright © 2016 Elsevier B.V. All rights reserved.

    About 70% of all people with severe burns die from related infections, despite advances in treatment regimens and the best efforts of nurses and doctors. Although silver-eluting wound dressings are available for addressing this problem, there is growing evidence of the deleterious effects of such dressings in delaying the healing process owing to cellular toxicity. A new concept of antibiotic-eluting composite wound dressings is described here. These dressings are based on a polyglyconate mesh coated with a porous poly-(dl-lactic-co-glycolic acid) matrix loaded with antibiotic drugs. The effect of antibiotic release on bacterial inhibition was studied, and cell cytotoxicity was examined. The dressings resulted in a 99.99% decrease in the viable counts of Pseudomonas aeruginosa and Staphylococcus albus at very high initial inoculations of 10⁷-10⁸ CFU ml⁻¹ after only 1 day, while such a decrease in Staphylococcus aureus was obtained within 3 days. Bacterial inhibition zones around the dressing material were found to persist for 2 weeks, indicating a long-lasting antimicrobial effect. Despite severe toxicity to bacteria, the dressing material was found to have no toxic effect on cultured fibroblasts, indicating that the new antibiotic-eluting wound dressings represent an effective option for selective treatment of bacterial infections.

    Objective The primary goal of this paper is to examine and clarify characteristics of binge eating in individuals with binge eating disorder (BED), particularly the duration of binge eating episodes, as well as potential differences between individuals with shorter compared to longer binge eating episodes. Method Two studies exploring binge eating characteristics in BED were conducted. Study 1 examined differences in clinical variables among individuals (N = 139) with BED who reported a short (< 2 hours) versus long (≥ 2 hours) average binge duration. Study 2 utilized an ecological momentary assessment (EMA) design to examine the duration and temporal pattern of binge eating episodes in the natural environment in a separate sample of nine women with BED. Results Participants in Study 1 who were classified as having long duration binge eating episodes displayed greater symptoms of depression and lower self-esteem, but did not differ on other measures of eating disorder symptoms, compared to those with short duration binge eating episodes. In Study 2, the average binge episode duration was approximately 42 minutes, and binge eating episodes were most common during the early afternoon and evening hours, as well as more common on weekdays versus weekends. Discussion Past research on binge episode characteristics, particularly duration, has been limited to studies of binge eating episodes in BN. This study contributes to the existing literature on characteristics of binge eating in BED. PMID:23881639

    Providing food or nutrition supplements during hemodialysis (HD) may be associated with improved nutritional status and reduced mortality; however, despite these potential benefits, eating practices vary across countries, regions, and clinics. Understanding present clinic practices and clinician experiences with eating during HD may help outline best practices in this controversial area. Therefore, the objective of this study was to examine clinical practices and experiences related to eating during HD treatment. We surveyed clinicians about their clinic practices during the 2014 International Society of Renal Nutrition and Metabolism Conference. We received 73 responses from six continents. Respondents were primarily dietitians (71%) working at units housed in a hospital (63%). Sixty-one clinics (85%) allowed patients to eat during treatment, with 47 of these patients (65%) actively encouraging eating. Fifty-three clinics (73%) provided food during HD. None of the nine clinics from North America, however, provided food during treatment. The majority (47 clinics; 64%) provided supplements during treatment. Clinics in the hospital setting were more likely to provide food during treatment, whereas outpatient clinics were less likely to provide nutrition supplements (P≤ 0.05 for both). We also asked clinicians about their experience with six commonly cited reasons to restrict eating during treatment using a four-point scale. Clinicians responded they observed the following conditions "rarely" or "never": choking (98%), reduced Kt/V (98%), infection control issues (96%), spills or pests (83%), gastrointestinal issues (71%), and hypotension (62%). Our results indicate that while eating is common during treatment in some areas, disparities may exist in global practices, and most of the proposed negative sequelae of eating during HD are not frequently observed in clinical practice. Whether these disparities in practice can explain global differences in albumin warrants

    The pain of acute herpes zoster (shingles) is severe and difficult to control. The medications used to control pain have a variety of important and potentially serious side effects. To the best of my knowledge, this is the first case report of using a plain topical occlusive dressing to reduce the pain of herpes zoster, avoiding the use of medication. A 40-year-old Caucasian man and a qualified physician (the author), developed a dermatomal vesicular rash consistent with herpes zoster. Applying plain topical occlusive dressings reduced the severity of his pain to an ignorable level. Plain topical occlusive dressings provide effective pain relief for acute herpes zoster, thereby avoiding the risks accompanying medication use.

    This systematic review considers the evidence supporting the use of prophylactic dressings for the prevention of pressure ulcer. Electronic database searches were conducted on 25 July 2013. The searches found 3026 titles and after removal of duplicate records 2819 titles were scanned against the inclusion and exclusion criteria. Of these, 2777 were excluded based on their title and abstract primarily because they discussed pressure ulcer healing, the prevention and treatment of other chronic and acute wounds or where the intervention was not a prophylactic dressing (e.g. underpads, heel protectors and cushions). Finally, the full text of 42 papers were retrieved. When these 42 papers were reviewed, 21 were excluded and 21 were included in the review. The single high-quality randomised controlled trial (RCT) and the growing number of cohort, weak RCT and case series all suggest that the introduction of a dressing as part of pressure ulcer prevention may help reduce pressure ulcer incidence associated with medical devices especially in immobile intensive care unit patients. There is no firm clinical evidence at this time to suggest that one dressing type is more effective than other dressings. © 2014 The Authors.

    A survey of ward nurses in medical, surgical, orthopaedic and rehabilitation specialties in relation to their care of wounds and their choice and use of wound dressings was carried out in May and August 2009 at St Mary's Hospital. Isle of Wight, UK. The objectives were to find out the distribution of wound types, and their characteristics, that were treated by ward nurses in the hospital, and to assess clinical practice in the use of wound dressings, before and after a bespoke programme of education and training. A visual framework to aid the ward nurses in the choice of dressings and frequency of change was introduced after the May 2009 survey. Following the nurses' education and training programme a repeat survey, using the same methodology, was conducted in August 2009. In the initial survey, 172 wounds were included (mean number of wounds per patient 1.64) and in the repeat one, 159 (mean number of wounds per patient 1.54). In both phases of the survey, the most common wound type was pressure ulcers, followed by surgical wounds; over 60% of the wounds were pressure ulcers, of which around half were category 1, and one-third were category 2. No category 4 ulcers were recorded. About one-third of the wounds had a duration of more than 21 days. On average, wound dressings were left in place for between two and three days, with 35% of dressings being changed on a daily basis. The mean cost of dressings per wound per week was observed to be lower in the repeat survey than in the initial one (£9.02 and £11.23 respectively). The number of undesirable reasons for changing the dressing was lower in the second phase than the first. The methodology of the surveys provided meaningful and valuable results over a short timescale, and increased understanding of wound types, their characteristics, and clinical practice. The surveys showed that data that can be collected in a short period using a simple tool can yield complex and revealing data trends. They also showed that

    We investigate the spectral signals and spatial images of a probe transmission signal, four-wave mixing (FWM), and six-wave mixing (SWM) under double dressing effects in an inverted Y-type system. Especially, we get the triple tailored nonlinear dispersion (about 60 MHz) of the dressed FWM and SWM through the interaction between electromagnetically induced transparency (EIT) windows and the Kerr nonlinearity. Moreover, SWM and dressed FWM with narrow linewidth are obtained through the tailoring of the three EIT windows, which is much narrower than the EIT. In addition, we first elaborate the modulation effect from the self-Kerr coefficient of FWM on the spot. We also investigate the spatial characteristics (defocusing, shifting, and splitting) of FWM and SWM induced by tailored self-Kerr and cross-Kerr effects among the relative fields. Such spatial shifting, splitting induced by the tailored nonlinear dispersion can be used for a higher contrast and high speed switch as well as a high resolution router.

    Seed dressing, i.e., the treatment of crop seeds with insecticides and/or fungicides, aiming to protect seeds from pests and diseases, is widely used in conventional agriculture. During the growing season, those crop fields often receive additional broadband herbicide applications. However, despite this broad utilization, very little is known on potential side effects or interactions between these different pesticide classes on soil organisms. In a greenhouse pot experiment, we studied single and interactive effects of seed dressing of winter wheat ( Triticum aestivum L. var. Capo ) with neonicotinoid insecticides and/or strobilurin and triazolinthione fungicides and an additional one-time application of a glyphosate-based herbicide on the activity of earthworms, soil microorganisms, litter decomposition, and crop growth. To further address food-web interactions, earthworms were introduced to half of the experimental units as an additional experimental factor. Seed dressings significantly reduced the surface activity of earthworms with no difference whether insecticides or fungicides were used. Moreover, seed dressing effects on earthworm activity were intensified by herbicides (significant herbicide × seed dressing interaction). Neither seed dressings nor herbicide application affected litter decomposition, soil basal respiration, microbial biomass, or specific respiration. Seed dressing did also not affect wheat growth. We conclude that interactive effects on soil biota and processes of different pesticide classes should receive more attention in ecotoxicological research.

    A novel rapid hemostatic and mild polyurethane-urea foam (PUUF) wound dressing was prepared by the particle leaching method and vacuum freeze-drying method using 4, 4-Methylenebis(cyclohexyl isocyanate), 4,4-diaminodicyclohexylmethane and poly (ethylene glycol) as raw materials. And X-ray diffraction (XRD), tensile test, differential scanning calorimetry (DSC) and thermogravimetry (TG) were used to its crystallinity, stress and strain behavior, and thermal properties, respectively. Platelet adhesion, fibrinogen adhesion and blood clotting were performed to evaluate its hemostatic effect. And H&E staining and Masson Trichrome staining were used to its wound healing efficacy. The results revealed the pore size of PUUF is 50-130μm, and its porosity is 71.01%. Porous PUUF exhibited good water uptake that was benefit to adsorb abundant wound exudates to build a regional moist environment beneficial for wound healing. The PUUF wound dressing exhibit better blood coagulation effect than commercial polyurethane dressing (CaduMedi). Though both PUUF and CaduMedi facilitated wound healing generating full re-epithelialization within 13days, PUUF was milder and lead to more slight inflammatory response than CaduMedi. In addition, PUUF wound dressing exhibited lower cytotoxicity than CaduMedi against NIH3T3 cells. Overall, porous PUUF represents a novel mild wound dressing with excellent water uptake, hemostatic effect and low toxicity, and it can promote wound healing and enhance re-epithelialization.

    In our previous work, we have attempted to develop a novel bacterial nanocellulose wound dressing which composed of both polyhexamethylene biguanide (PHMB) as an antimicrobial agent and sericin as an accelerative wound healing component. The loading sequence and concentration of PHMB and sericin were optimized to provide the wound dressing with the most effective antimicrobial activity and enhanced collagen production. In this study, further in vitro, in vivo, and clinical studies of this novel wound dressing were performed to evaluate its safety, efficacy, and applicability. For the in vitro cytotoxic test with L929 mouse fibroblast cells, our novel dressing was not toxic to the cells and also promoted cell migration as good as the commercially available dressing, possibly due to the component of sericin released. When implanted subcutaneously in rats, the lower inflammation response was observed for the novel dressing implanted, comparing to the commercially available dressing. This might be that the antimicrobial PHMB component of the novel dressing played a role to reduce infection and inflammation reaction. The clinical trial patch test was performed on the normal skin of healthy volunteers to evaluate the irritation effect of the dressing. Our novel dressing did not irritate the skin of any volunteers, as characterized by the normal levels of erythema and melanin and the absence of edema, papule, vesicle, and bullae. Then, the novel dressing was applied for the treatment of full-thickness wounds in rats. The wounds treated with our novel dressing showed significantly lower percentage of wound size and higher extent of collagen formation mainly due to the activity of sericin. We concluded that our novel bacterial nanocellulose incorporating PHMB and sericin was a safe and efficient wound dressing material for further investigation in the wound healing efficacy in clinic.

    It has been demonstrated that patients with chronic wounds experience the most pain during dressing changes. Currently, researchers focus mostly on analgesics and appropriate dressing materials to relieve pain during dressing changes of chronic wounds. However, the effect of nonpharmacologic interventions, such as virtual reality distraction, on pain management during dressing changes of pediatric chronic wounds remains poorly understood. To investigate the effect of virtual reality distraction on alleviating pain during dressing changes in children with chronic wounds on their lower limbs. A prospective randomized study. A pediatric center in a tertiary hospital. Sixty-five children, aged from 4 to 16 years, with chronic wounds on their lower limbs. Pain and anxiety scores during dressing changes were recorded by using the Wong-Baker Faces picture scale, visual analogue scale, and pain behavior scale, as well as physiological measurements including pulse rate and oxygen saturation. Time length of dressing change was recorded. Virtual reality distraction significantly relieved pain and anxiety scores during dressing changes and reduced the time length for dressing changes as compared to standard distraction methods. The use of virtual reality as a distraction tool in a pediatric ward offered superior pain reduction to children as compared to standard distractions. This device can potentially improve clinical efficiency by reducing length time for dressing changes. Copyright © 2015 American Society for Pain Management Nursing. Published by Elsevier Inc.

    Background Topical antimicrobials, such as silver dressings, are progressively being used alongside systemic antibiotics to provide adjunctive, antimicrobial therapy to wounds that are clinically infected or at risk of infection. To help improve wound management, dressings that use Safetac soft silicone technology in combination with a silver-impregnated foam dressing material were developed by Mölnlycke Health Care (Gothenburg, Sweden). The range comprises Mepilex Ag, Mepilex Border Ag and Mepilex Transfer Ag. Aims A literature review was undertaken to identify and summarise clinical data from the entire evidence hierarchy, as well as data from in vitro tests, which support the use of silver-containing foam dressings with Safetac. Method The MEDLINE (National Library of Medicine, Bethesda, US) and EMBASE (Elsevier BV, Amsterdam, Netherlands) bibliographic databases were searched. In addition, abstract books and proceedings documents relating to national and international conferences were scanned in order to identify presentations (oral, e-poster and poster) of relevance to the review. Results In vitro test results showed that the silver-containing foam dressings with Safetac have both rapid and sustained activity against a range of wound pathogens, reducing planktonic and established biofilm cultures, and preventing biofilm formation. In numerous clinical studies, silvercontaining foam dressings with Safetac were used to manage wound bioburden effectively and resolve signs of localised infection in both acute wounds (such as surgical, traumatic and burn injuries) and chronic wounds (such as leg ulcers, pressure ulcers (PUs), diabetic foot ulcers (DFUs), and cancerous wounds). Studies reported that silver-containing foam dressings with Safetac are easy to use, provide an optimal environment for wound healing, and are associated with atraumatic and virtually painfree removal. As well as being clinically effective, they are reported to be cost-effective when used on

  8. What #theDress reveals about the role of illumination priors in color perception and color constancy

    The disagreement between people who named #theDress (the Internet phenomenon of 2015) “blue and black” versus “white and gold” is thought to be caused by individual differences in color constancy. It is hypothesized that observers infer different incident illuminations, relying on illumination “priors” to overcome the ambiguity of the image. Different experiences may drive the formation of different illumination priors, and these may be indicated by differences in chronotype. We assess this hypothesis, asking whether matches to perceived illumination in the image and/or perceived dress colors relate to scores on the morningness-eveningness questionnaire (a measure of chronotype). We find moderate correlations between chronotype and illumination matches (morning types giving bluer illumination matches than evening types) and chronotype and dress body matches, but these are significant only at the 10% level. Further, although inferred illumination chromaticity in the image explains variation in the color matches to the dress (confirming the color constancy hypothesis), color constancy thresholds obtained using an established illumination discrimination task are not related to dress color perception. We also find achromatic settings depend on luminance, suggesting that subjective white point differences may explain the variation in dress color perception only if settings are made at individually tailored luminance levels. The results of such achromatic settings are inconsistent with their assumed correspondence to perceived illumination. Finally, our results suggest that perception and naming are disconnected, with observers reporting different color names for the dress photograph and their isolated color matches, the latter best capturing the variation in the matches.

    As allograft and xenografts are not available in Islamic countries, amniotic membrane seems to be an effective alternative in the management of deep burns. Its proven bioactivities and modest price suggest that it might be superior to synthetic dressings. Forty-six patients were enrolled in this randomized, controlled clinical trial conducted in the Burn Unit at Suez Canal University Hospital, Ismailia, Egypt. All age groups and both gender were included in the study. Only patients with less than 50% total body surface area burned were included, thus minimizing the dropouts in both groups. All were either second or third degree. These patients were randomly assigned either to group I: amniotic membrane (Biomembrane) dressing, or group II: polyurethane membrane (Tegaderm) dressing. Those in group I demonstrated a significantly lower rate of infection and required less frequent dressing changes than those in group II. They also sustained less electrolyte and albumin loss. The rate of healing in the amniotic membrane group was significantly faster than in the polyurethane group. Furthermore, pain was significantly less when Biomembrane was used. Based on these findings, we recommend the use of lyophilized gamma-irradiated amniotic membrane as an effective alternative for allograft and xenografts in Islamic countries and the Jewish population.

    Cotton gauze with alpha cyanoacrylate was used for alveolopalatal wound dressing after alveolar bone grafting to treat 93 alveolar clefts in 74 cleft patients to reduce mechanical injuries, tension for wound dehiscence, and adhesion of food remnants. T-shaped cotton gauze was put on the gingivoperiosteal flaps and was impregnated with cyanoacrylate. The procedure required no preoperative preparation and its intraoperative execution took less than 5 minutes. The gauze with cyanoacrylate was removed approximately 1 week after surgery. No infection was observed at any of the operational sites, but tiny fistulas developed at four of them. The mean bone graft score was 1.4 point. No complications such as thermal injury resulted from the use of cyanoacrylate. Gauze impregnated with cyanoacrylate proved to be a convenient and dependable dressing for alveolopalatal wounds resulting from gingivoperiosteoplasty for alveolar bone grafting.

    Keratin is an interesting protein needed for wound healing and tissue recovery. We have recently proposed a new, simple and inexpensive method to obtain fur and hair keratin-derived biomaterials suitable for medical application. The aim of the study was to evaluate the role of the fur keratin-derived protein (FKDP) dressing in the allogenic full-thickness surgical skin wound model. The data obtained using scanning electron microscopy showed that employed processed biomaterial had higher surface porosity compared with control raw material. From the MTS test, it was found keratin biomaterial is not only toxic to the NIH/3T3 cell line (p < 0.05), but also enhances cell proliferation compared with the control. In vivo studies have shown keratin dressings are tissue biocompatible, accelerate wound closure and epithelialization to the statistically significant differences on day 5 (p < 0.05) in comparison to control wounds. Histological examination revealed, that in FKDP-treated wounds the inflammatory response contained predominantly macrophages whilst their morphological untreated variants showed mixed cell infiltrates rich in neutrophils. Predominant macrophages based response creates more favorable environment for healing. In FKDP-dressed wounds the number of microhemorrhages was also significantly decreased (p < 0.05) as compared with undressed wounds. Applied keratin dressing favors reconstruction of a more regular skin structure and assures better cosmetic effect in terms of scar formation and appearance. In conclusion, fur keratin-derived protein dressings significantly accelerated wound healing in the mouse model. Further studies are needed to determine the molecular mechanisms involved in the multilayer wound healing process and to assess the possible use of these dressings for medical purposes. © 2016 by the Wound Healing Society.

    In today's business world, there's no shortage of know-how. When companies get into trouble, their executives have vast resources at their disposal: their own experiences, colleagues' ideas, reams of computer-generated data, thousands of publications, and consultants armed with the latest managerial concepts and tools. But all too often, even with all that knowledge floating around, companies are plagued with an inertia that comes from knowing too much and doing too little--a phenomenon the authors call the knowing-doing gap. The gap often can be traced to a basic human propensity: the willingness to let talk substitute for action. When confronted with a problem, people act as though discussing it, formulating decisions, and hashing out plans for action are the same as actually fixing it. And after researching organizations of all shapes and sizes, the authors concluded that a particular kind of talk is an especially insidious inhibitor of action: "smart talk." People who can engage in such talk generally sound confident and articulate; they can spout facts and may even have interesting ideas. But such people often exhibit the less benign aspects of smart talk as well: They focus on the negative, and they favor unnecessarily complex or abstract language. The former lapses into criticism for criticism's sake; the latter confuses people. Both tendencies can stop action in its tracks. How can you shut the smart-talk trap and close the knowing-doing gap? The authors lay out five methods that successful companies employ in order to translate the right kind of talk into intelligent action.

    We discuss the properties of atom-photon bound states in waveguide QED systems consisting of single or multiple atoms coupled strongly to a finite-bandwidth photonic channel. Such bound states are formed by an atom and a localized photonic excitation and represent the continuum analog of the familiar dressed states in single-mode cavity QED. Here we present a detailed analysis of the linear and nonlinear spectral features associated with single- and multiphoton dressed states and show how the formation of bound states affects the waveguide-mediated dipole-dipole interactions between separated atoms. Our results provide both a qualitative and quantitative description of the essential strong-coupling processes in waveguide QED systems, which are currently being developed in the optical and microwave regimes.

    To investigate whether type of goals and motives underlying females' eating regulation are associated differentially with daily eating behaviours, dependent upon weight and age category. 99 late adolescent female dieters (Mage = 18.94) and 98 adult female dieters (Mage = 45.06), 23.6% of which were overweight, completed a questionnaire and a 7-day diary assessment. Descriptive analysis and path analysis were performed to investigate the research questions. Healthy eating behaviours (HEHS), drive for thinness and binge eating symptoms (EDI). Appearance-focused and controlled eating regulation were positively related to disordered eating symptoms throughout the week. In contrast, autonomous and health-focused eating regulation were associated positively with healthy eating behaviours and were either related negatively or unrelated to disordered eating symptoms. Mean level differences in motivation and eating behaviours emerged according to age and weight status. However, the examined structural model was similar for late adolescent and adult dieters and only few differences emerged between normal-weight and overweight dieters. Dieters' type of motivation helps to explain when eating regulation relates to healthy and disordered eating symptoms.

    In the grinding of high quality fused silica parts with complex surface or structure using ball-headed metal bonded diamond wheel with small diameter, the existing dressing methods are not suitable to dress the ball-headed diamond wheel precisely due to that they are either on-line in process dressing which may causes collision problem or without consideration for the effects of the tool setting error and electrode wear. An on-machine precision preparation and dressing method is proposed for ball-headed diamond wheel based on electrical discharge machining. By using this method the cylindrical diamond wheel with small diameter is manufactured to hemispherical-headed form. The obtained ball-headed diamond wheel is dressed after several grinding passes to recover geometrical accuracy and sharpness which is lost due to the wheel wear. A tool setting method based on high precision optical system is presented to reduce the wheel center setting error and dimension error. The effect of electrode tool wear is investigated by electrical dressing experiments, and the electrode tool wear compensation model is established based on the experimental results which show that the value of wear ratio coefficient K' tends to be constant with the increasing of the feed length of electrode and the mean value of K' is 0.156. Grinding experiments of fused silica are carried out on a test bench to evaluate the performance of the preparation and dressing method. The experimental results show that the surface roughness of the finished workpiece is 0.03 μm. The effect of the grinding parameter and dressing frequency on the surface roughness is investigated based on the measurement results of the surface roughness. This research provides an on-machine preparation and dressing method for ball-headed metal bonded diamond wheel used in the grinding of fused silica, which provides a solution to the tool setting method and the effect of electrode tool wear.

    The purpose of this study was to examine the efficacy of silver-releasing dressings in the management of non-healing chronic wounds. Non-healing chronic wounds often have a negative physical impact on patients and place a financial burden on healthcare systems. Silver dressings are wound products designed to control infection and provide a wound environment conducive to healing. However, validation of the clinical efficacy of these dressings is lacking. Systematic review and meta-analysis. A systematic search of the major electronic databases PubMed, CINAHL, Cochrane, MEDLINE, British Nursing Index, EBSCO, OCLC and Proquest between 1950-June 2007 was conducted. Hand searches of selected periodicals, textbooks and checking reference lists and contacting experts was also performed. Eight studies were selected from a potentially relevant 1957 references screened. Analysis incorporated data from 1399 participants in the eight randomised control trials. We found that silver dressings significantly improved wound healing (CI(95): 0.16-0.39, p < 0.001), reduced odour (CI(95): 0.24-0.52, p < 0.001) and pain-related symptoms (CI(95): 0.18-0.47, p < 0.001), decreased wound exudates (CI(95): 0.17-0.44, p < 0.001) and had a prolonged dressing wear time (CI(95): 0.19-0.48, p = 0.028) when compared with alternative wound management approaches. An analysis of sensitivity in these studies by subgroup analysis generally supported these associations. Furthermore, studies indicated an improvement in quality of life (CI(95): 0.04-0.33, p = 0.013) using silver dressings in wound management with no associated severe adverse events. This meta-analysis confirms the effectiveness of silver dressings in wound healing and improving patients' quality of life. However, it also highlights the need for additional well-designed randomised controlled trials to evaluate the effectiveness of silver-related dressings further. The results of this study provide objective data on the effectiveness of

    2013-08-01

    Facial involvement of atopic eczema in young children can be difficult to manage. Chronic scratching and rubbing, combined with parental reluctance to use topical corticosteroids on the face, often results in recalcitrant facial eczema. While wet wraps are a useful management option for moderate/severe atopic eczema involving the trunk and limbs they are difficult to use on the face. We describe the use of a face-mask using a widely available adhesive hydrocolloid dressing (DuoDerm extra thin) in three children with recalcitrant facial atopic eczema. Symptomatic control of itch or soreness was obtained within hours and the facial atopic eczema was markedly improved by 7 days. The face-masks were easy to apply, each lasting 1-4 days. One patient had a single adjuvant application of a potent topical corticosteroid under the hydrocolloid dressing. All three patients had long remissions (greater than 3 months) of their facial eczema, although all continued to have significant eczema involving their trunk and limbs. Face-masks made from hydrocolloid dressings, with or without topical corticosteroids, are worth considering in children with recalcitrant facial eczema. © 2012 The Author.

    The success of skin grafting is dependent on the interplay between many factors including nutrient uptake and vascular in-growth. To allow this, it is important that the graft is immobile and traditionally a 'pressure dressing' has been placed over the graft to improve outcome and graft 'take'. We present the findings of our comparative study of full-thickness skin grafts performed in the head, neck and face region over a period of 24 months. We felt that there was an unacceptably high infection rate and graft failure using pressure dressings. Data was collected retrospectively from the case notes on 70 patients who had undergone full-thickness skin grafting to the head, neck and face over a 2 year period. Thirty-five patients underwent grafting with pressure dressing and 35 without. The group with the pressure dressing had the same 'bolster' specification-type dressing and those without had their graft 'quilted' in and chloramphenicol ointment applied topically. Success was determined by the percentage 'take' of the grafts and absence of infection i.e. purulence. Infection in those with a pressure dressing stood at 26 % in contrast to those without, at 9 %. Without a pressure dressing we observed no total graft failures, compared to 6 % in those with a pressure dressing. The results confirmed the perception that there was a higher infection and graft failure rate where a pressure dressing was applied; however, this was not a statistically significant difference and a randomised control trial with a larger sample size would be required to validate the results.

  5. Economic and clinical contributions of an antimicrobial barrier dressing: a strategy for the reduction of surgical site infections.

    In patients at risk of surgical site infection (SSI), there is evidence that an antimicrobial barrier dressing (Acticoat* ) applied immediately post-procedure is effective in reducing the incidence of infection. The objective of this study was to assess when it is appropriate to use an antimicrobial barrier dressing rather than a post-operative film dressing, by evaluating the net cost and budget impact of the two strategies. An economic model was developed, which estimates expected expenditure on dressings and the expected costs of surgical site infection during the initial inpatient episode, based on published literature on the pre-discharge costs of surgical infection and the efficacy of an antimicrobial barrier dressing in preventing SSI. At an SSI risk of 10%, an antimicrobial barrier dressing strategy is cost neutral if the incidence of infection is reduced by at least 9% compared with a post-operative film dressing. At 35% efficacy, expenditure on dressings would be higher by £30,760 per 1000 patients, and the cost of treating infection would be lower by £111,650, resulting in a net cost saving of £80,890. The break-even infection risk for cost neutrality is 2.6%. Although this cost analysis is based on published data, there are limitations in methodology: the model is dependent on and subject to the limitations of the data used to populate it. Further studies would be useful to increase the robustness of the conclusions, particularly in a broader range of surgical specialties. A strategy involving the use of an antimicrobial barrier dressing in patients at moderate (5-10%) or high (>10%) risk of infection appears reasonable and cost saving in light of the available clinical evidence.

    To describe eating patterns, prevalence of problematic eating behaviors, and determine factors associated with binge eating disorder (BED), before bariatric surgery. Before surgery, 2,266 participants (median age 46 years; 78.6% female; 86.9% white; median body mass index 45.9 kg/m(2) ) of the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study completed eating behavior survey items in the self-administered LABS-2 Behavior form. Other measures included the Alcohol Use Disorder Identification Test, the LABS-2 Psychiatric and Emotional Test Survey, the Beck Depression Inventory, the Interpersonal Support Evaluation List-12, the Short Form-36 Health Survey, and Impact of Weight Quality of Life-Lite Survey. The majority (92.1%) of participants reported eating dinner regularly, whereas just over half (54.0%) reported eating breakfast regularly. Half of the participants reported eating at least four meals/week at restaurants; two meals/week were fast food. Loss of control eating was reported by 43.4%, night eating syndrome by 17.7%; 15.7% satisfied criteria for binge eating disorder (BED), 2% for bulimia nervosa. Factors that independently increased the odds of BED were being a college graduate, eating more times per day, taking medication for psychiatric or emotional problems, and having symptoms of alcohol use disorder, lower self-esteem and greater depressive symptoms. Before undergoing bariatric surgery a substantial proportion of patients report problematic eating behaviors. Several factors associated with BED were identified, most suggesting other mental health problems, including higher levels of depressive symptomotology. The strengths of this study include the large sample size, the multi-center design and use of standardized assessment practices. © 2014 Wiley Periodicals, Inc.

    Top-dressing is a method of broiler litter management in which a thin layer of new, clean litter material is spread over the top of previously used litter prior to placement of a new flock. This fresh layer of bedding material increases the absorptive capacity of the litter and decreases litter caking. Although this practice has been widely used in the poultry industry for many years, no research has been conducted to quantify the effects the practice has on broiler performance, litter production rates, and nutrient content, or the ability of broiler litter to retain manure N and prevent volatilization. An experiment was conducted to quantify these parameters under simulated commercial conditions in a research facility. Nine consecutive flocks of broilers were reared on recycled broiler litter that had previously been used for 9 flocks. Control pens received no litter treatment whereas top-dressed pens received a thin layer of new rice hulls (1 to 2 cm) before the placement of each flock. Nitrogen loss was calculated using the mass balance method. Average broiler performance was not different between the top-dressed and control pens. Top-dressing of litter significantly (P < 0.05) reduced caked litter production compared with control pens in 6 of 9 flocks. However, average total litter production over all 9 flocks was not different between the 2 litter management strategies. In all flocks, litter N content was significantly reduced in top-dressed pens compared with control pens. As a result, litter C:N ratios were significantly higher for pens with top-dressed litter. Differences in N loss between the treatments were not consistent. Average N loss for all flocks was 10.61 and 11.92 g of N/kg of marketed broiler for control and top-dressed pens, respectively, or 20.1 and 22.5% of N inputs, respectively. Based on this experiment, top-dressing of recycled broiler litter would not be recommended as a strategy to reduce the volatilization of N from broiler rearing

    Drug-induced hypersensitivity or Drug Reaction with Eosinophilia and Systemic Symptom (DRESS) is a severe adverse drug-induced reaction. Diagnosing DRESS is challenging due to the diversity of cutaneous eruption and organs involved. Most of the aromatic anticonvulsants, such as phenytoin, phenobarbital, and carbamazepine, can induce DRESS. Culprit drug withdrawal and corticosteroids constituted the mainstay of DRESS treatment. We describe a 6 year-old boy who presented fever and rash 4 weeks after starting carbamazepine. Investigation revealed leukocytosis, atypical lymphocytosis, and elevated serum transaminases. The diagnosis of DREES syndrome was made, Carbamazepine was stopped and replaced initially by Clobazam and by Valproic acid after discharge, no systemic corticotherapy was prescribed. Symptoms began to resolve within two weeks, and by one month later her laboratory values had returned to normal. The aim of this work is to raise awareness general practitioner and pediatricians to suspect Dress syndrome in patients who present with unusual complaints and skin findings after starting any antiepileptic drug.

    There is initial evidence that beliefs about the eating behaviour of others (perceived eating norms) can influence children's vegetable consumption, but little research has examined the mechanisms explaining this effect. In two studies we aimed to replicate the effect that perceived eating norms have on children's vegetable consumption, and to explore mechanisms which may underlie the influence of perceived eating norms on children's vegetable consumption. Study 1 investigated whether children follow perceived eating norms due to a desire to maintain personal feelings of social acceptance. Study 2 investigated whether perceived eating norms influence eating behaviour because eating norms provide information which can remove uncertainty about how to behave. Across both studies children were exposed to vegetable consumption information of other children and their vegetable consumption was examined. In both studies children were influenced by perceived eating norms, eating more when led to believe others had eaten a large amount compared to when led to believe others had eaten no vegetables. In Study 1, children were influenced by a perceived eating norm regardless of whether they felt sure or unsure that other children accepted them. In Study 2, children were most influenced by a perceived eating norm if they were eating in a novel context in which it may have been uncertain how to behave, as opposed to an eating context that children had already encountered. Perceived eating norms may influence children's eating behaviour by removing uncertainty about how to behave, otherwise known as informational social influence. Copyright © 2017 The Authors.

    Objective We sought to describe meal and snack frequencies of individuals with recurrent binge eating and examine the association between these eating patterns and clinical correlates. Method Data from 106 women with a minimum diagnosis of recurrent binge eating were utilized. Meal and snack frequencies were correlated with measures of weight, eating disorder features, and depression. Participants who ate breakfast every day (n=25) were compared with those who did not (n=81) on the same measures. Results Breakfast was the least, and dinner the most, commonly consumed meal. Evening snacking was the most common snacking occasion. Meal patterns were not significantly associated with clinical correlates; however, evening snacking was associated with binge eating. Discussion Our findings largely replicated those reported in earlier research. More research is needed to determine the role of breakfast consumption in binge eating. PMID:21661003

    Twenty years have passed from the International Classification of Diseases, Tenth Revision (ICD-10) to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and, in the meanwhile, a lot of research data about eating disorders has been published. This article reviews the main modifications to the classification of eating disorders reported in the "Feeding and Eating Disorders" chapter of the DSM-5, and compares them with the ICD-10 diagnostic guidelines. Particularly, we will show that DSM-5 criteria widened the diagnoses of anorexia and bulimia nervosa to less severe forms (so decreasing the frequency of Eating Disorders, Not Otherwise Specified (EDNOS) diagnoses), introduced the new category of Binge Eating Disorder, and incorporated several feeding disorders that were first diagnosed in infancy, childhood, or adolescence. On the whole, the DSM-5 revision should allow the clinician to make more reliable and timely diagnoses for eating disorders.

    Aloe vera and curcumin loaded oxidized pectin-gelatin (OP-Gel) matrices were used as antimicrobial finishes on nonwoven cotton fabrics to produce composite wound care devices. The drug release characteristics of the biocomposite dressings indicated that curcumin is released through a biphasic mechanism - erosion of the polymeric matrix, followed by diffusion, while aloe vera is released upon leaching of the polymeric matrix. A 50/50 composition of aloe vera/curcumin was used to fabricate OP-Gel-Aloe Curcumin dressings. However, contrary to our expectations, OP-Gel-Aloe Curcumin dressings exhibited lesser antimicrobial activity compared to OP-Gel-Aloe and OP-Gel-Curcumin dressings. The cytocompatibility of the fabricated dressings was evaluated using NIH3T3 mouse fibroblast cells. OP-Gel-Aloe treated fibroblasts had the highest viability, with the matrices providing a substrate for good cell attachment and proliferation. On the other hand, OP-Gel-Curcumin and OP-Gel-Aloe Curcumin seemed to have induced apoptosis in NIH3T3 cells. In vivo wound healing analysis was carried out using an excisional splint wound model on C57BL/6J mice. OP-Gel-Aloe treated wounds exhibited very rapid healing with 80% of the wound healing in just 8 days. Furthermore, aloe vera exerted a strong anti-inflammatory effect and prominent scar prevention. Histological examination revealed that an ordered collagen formation and neovascularization could be observed along with migration of nuclei. Therefore, OP-Gel-Aloe biocomposite dressings are proposed as viable materials for effective wound management. Copyright © 2015 Elsevier B.V. All rights reserved.

    This paper is a systematic review with the objective of determining the effectiveness of silver-releasing dressing in the management of infected chronic wounds. Chronic wounds exhibit increased bacterial burdens which not only result in a negative physical impact on patients, impairing their quality of life, but also increase treatment costs. Silver dressings are wound products designed to control and inhibit infection and provide a wound environment conducive to healing. However, there is limited evidence on their effectiveness in doing so. A systematic review of literature from 1950-May 2007 was conducted using the PubMed, CINAHL, Cochrane, MEDLINE, British Nursing Index, EBSCO Host, OCLC, Proquest and PsychInfo databases. The review included randomised or non-randomised control trials, published in English or non-English, of silver-releasing dressings in infected chronic wounds. Of the over 1957 potentially releasing studies examined, 14 pertinent articles involving 1285 participants were identified. Almost all the participants reported one or more statistically significant outcomes. The main points to emerge from this review of studies are that silver-releasing dressings show positive effects on infected chronic wounds. The quality of the trials was limited by the potential for bias associated with inadequate concealment, no detailed description of the outcome measurement and no reported intention-to-treat analysis. Moreover, problems existed in some studies with confounding factors. The review clearly highlights the need for well-designed, methodologically standardised outcome measurement research into the effectiveness of silver-releasing dressings. It also points to the need for a comprehensive assessment of wound bed status in further studies. This review strengthens the case for the use of silver dressings when managing infected chronic wounds. They appear more effective and are tolerated well by patients. However, their use should be accompanied by a

    To prevent the recurrence of earlobe keloids after surgical removal, a reliable and safe postoperative treatment method is critical. To the authors' knowledge, no studies have elucidated the most effective postoperative dressing method for preventing the recurrence of earlobe keloids. This study aimed to compare keloid recurrence rates in patients whose keloids were dressed using conventional methods (plain gauze or a polyvinyl alcohol sponge) with those of a matched cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. This observational case-control study compared a retrospective cohort of patients whose keloids were dressed using conventional methods with a matched prospective cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. The study included patients with pathologically confirmed earlobe keloids that were surgically excised with primary closure. Patients 8 years of age or older underwent adjuvant pressure therapy with magnets at the study hospital. Patients were excluded from the study if they were unavailable for follow-up evaluation, if they had received additional adjuvant therapy during treatment, or if histologic confirmation of a keloid was not obtained. Matched-pair analysis was performed using the McNemar test. Treatment outcome was evaluated as recurrence or nonrecurrence. Overall, 9 (11.2%) of the 80 study patients experienced recurrence. The recurrence rate was significantly lower in the matched case group (2 of 40, 5%) than in the matched control group (7 of 40, 17.5%) during the follow-up period of 18 months (p=0.0253). The authors' novel dressing of magnets and hydrocolloid materials appears to be effective in reducing earlobe keloid recurrence.

    With a forward cone emitting from the strong pump laser in a thermal rubidium atomic vapor, we investigate the non-degenerate parametrically amplified four-wave mixing (PA-FWM) process with dressing effects in a three-level "double-Λ" configuration both theoretically and experimentally. By seeding a weak probe field into the Stokes or anti-Stokes channel of the FWM, the gain processes are generated in the bright twin beams which are called conjugate and probe beams, respectively. However, the strong dressing effect of the pump beam will dramatically affect the gain factors both in the probe and conjugate channels, and can inevitably impose an influence on the quantum effects such as entangled degree and the quantum noise reduction between the two channels. We systematically investigate the intensity evolution of the dressed gain processes by manipulating the atomic density, the Rabi frequency and the frequency detuning. Such dressing effects are also visually evidenced by the observation of Autler-Townes splitting of the gain peaks. The investigation can contribute to the development of quantum information processing and quantum communications.

    Non-human animal studies demonstrate relationships between stress and selective intake of palatable food. In humans, exposure to laboratory stressors and self-reported stress are associated with greater food intake. Large studies have yet to examine chronic stress exposure and eating behavior. The current study assessed the relationship between stress (perceived and chronic), drive to eat, and reported food frequency intake (nutritious food vs. palatable non-nutritious food) in women ranging from normal weight to obese (N=457). Greater reported stress, both exposure and perception, was associated with indices of greater drive to eat-including feelings of disinhibited eating, binge eating, hunger, and more ineffective attempts to control eating (rigid restraint; r's from .11 to .36, p's<.05). These data suggest that stress exposure may lead to a stronger drive to eat and may be one factor promoting excessive weight gain. Relationships between stress and eating behavior are of importance to public health given the concurrent increase in reported stress and obesity rates. Copyright © 2011 Elsevier Ltd.

    An ethyl alcohol-precipitated silk sericin/PVA scaffold that controlled the release of silk sericin was previously developed and applied for the treatment of full-thickness wounds in rats and demonstrated efficient healing. In this study, we aimed to further evaluate the clinical potential of this scaffold, hereafter called "silk sericin-releasing wound dressing", for the treatment of split-thickness skin graft donor sites by comparison with the clinically available wound dressing known as "Bactigras®". In vitro characterization and in vivo evaluation for safety of the wound dressings were performed. A clinical trial of the wound dressings was conducted according to standard protocols. The sericin released from the wound dressing was not toxic to HaCat human keratinocytes. A peel test indicated that the silk sericin-releasing wound dressing was less adhesive than Bactigras®, potentially reducing trauma and the risk of repeated injury upon removal. There was no evidence of skin irritation upon treatment with either wound dressing. When tested in patients with split-thickness skin graft donor sites, the wounds treated with the silk sericin-releasing wound dressing exhibited complete healing at 12 ± 5.0 days, whereas those treated with Bactigras® were completely healed at 14 ± 5.2 days (p = 1.99 × 10(-4)). In addition, treatment with the silk sericin-releasing wound dressing significantly reduced pain compared with Bactigras® particularly during the first 4 postoperative days (p = 2.70 × 10(-5) on day 1). We introduce this novel silk sericin-releasing wound dressing as an alternative treatment for split-thickness skin graft donor sites.

    Five proprietary and one experimental dressing were compared with no treatment in their ability to aid healing of mulesing wounds in over 1900 young lambs. Healing was judged as the completeness of shrinkage of the mulesing cuts and the condition of scabs on the new skin surface. When assessed at 21 d it was found that treatment with Heriots Crown Wound Powder or Coopers Mulesing Powder offered a significant advantage over leaving the wounds untreated. Neither aqueous organophosphate washes, Defiance nor Defiance containing 0.08% chlorfenvinphos offered any healing advantage over controls. However, washing the wounds with an aqueous organophosphate solution aided healing more than the Defiance-based dressings. It was considered that the powders or the washes encouraged quick scab formation either by creating a dry covering (powders) or by washing away blood and allowing fast drying of the wound. The Defiance-type dressings slowed healing by keeping the wound moist for up to 10 d, but healing was not significantly different to the untreated group by 21 d.

    Nanocellulose from wood is a novel biomaterial, which is highly fibrillated at the nanoscale. This affords the material a number of advantages, including self-assembly, biodegradability and the ability to absorb and retain moisture, which highlights its potential usefulness in clinical wound-dressing applications. In these in vitro studies, the wound pathogen Pseudomonas aeruginosa PAO1 was used to assess the ability of two nanocellulose materials to impair bacterial growth (<48 h). The two nanocelluloses had a relatively small fraction of residual fibres (<4%) and thus a large fraction of nanofibrils (widths <20 nm). Scanning electron microscopy and confocal laser scanning microscopy imaging demonstrated impaired biofilm growth on the nanocellulose films and increased cell death when compared to a commercial control wound dressing, Aquacel(®). Nanocellulose suspensions inhibited bacterial growth, whilst UV-vis spectrophotometry and laser profilometry also revealed the ability of nanocellulose to form smooth, translucent films. Atomic force microscopy studies of the surface properties of nanocellulose demonstrated that PAO1 exhibited markedly contrasting morphology when grown on the nanocellulose film surfaces compared to an Aquacel(®) control dressing (p<0.05). This study highlights the potential utility of these biodegradable materials, from a renewable source, for wound dressing applications in the prevention and treatment of biofilm development.

    Honey-based wound dressings have been used worldwide since ancient times. A honey product received US Federal Drug Administration approval in 2007, making this dressing an option for wound care. Honey has been found to exert anti-inflammatory and antibacterial effects without antibiotic resistance, promote moist wound healing, and facilitate debridement. However, it may cause a stinging pain. As is true of any wound dressing, its use must be carefully selected and monitored. Continued research is needed to add to its evidence base. This article provides a summary of the current evidence base for the use of honey and a review of its therapeutic effects and discusses implications for WOC nursing practice.

    There is a broad research interest in the search for alternatives to chemical additives for use as natural food preservatives. Although many natural compounds have biological in vitro properties evidenced, in situ studies are still scarce. This study evaluated the effect of oregano essential oil (OEO) and salt (NaCl) concentrations against Escherichia coli (ATCC 8739), in salad dressing, using the response surface methodology. The experiment included a 2 2 central composite rotatable design (CCRD) in a total of 11 formulations of salad dressings. Oregano essential oil was characterized by gas chromatography and salad dressings by ash, lipids, proteins and moisture. OEO was composed mainly by carvacrol (65.1%) and p-cymene (12.0%). Salad dressings showed similar chemical profiles. A mathematical model for the prediction of the antibacterial activity in salad dressing was obtained. The results revealed that the interaction between OEO and salt showed effect on the bacterial count. However, the effect of salt was negative suggesting that the highest NaCl concentrations decreases the bacterial count. Therefore, within the parameters studied, the use of OEO to control E. coli in salad dressing can be considered promising and allows reduction in the levels of salt to be incorporated in food.

    Background Restrained Eating, i.e. the tendency to restrict dietary intake to control body-weight, often emerges during adolescence and may result in changes in circadian eating patterns. Objective The objective of the present investigation was to determine the cross-sectional relevance of restrained eating for characteristics of circadian eating pattern in adolescents and whether changes in restrained eating are accompanied by concurrent changes in circadian eating pattern over the course of adolescence. Methods Two questionnaires assessing restrained eating (Score 0–30) with parallel 3-day weighed dietary records from two different time points were available from 209 (♂:101, ♀:108) 11–18 year old adolescents of the DONALD study. Mixed linear regression models were used to analyze whether restrained eating was associated with eating occasion frequency, snack frequency and morning and evening energy intake [in % of daily energy intake, %E]. Linear regression models were used to examine whether changes in restrained eating were associated with changes in the mentioned variables. Results Among girls, greater restrained eating was cross-sectionally associated with higher morning energy intake (p = 0.03). Further, there was a tendency towards lower evening energy intake with higher levels of restrained eating for the whole sample (p = 0.06). No cross-sectional associations were found with eating occasion or snack frequency. Each one-point increase in restrained eating during adolescence was related to a concurrent decrease in eating occasion frequency by 0.04 (95% CI -0.08; -0.01, p = 0.02) and in evening energy intake by 0.36%E (95% CI -0.70; -0.03, p = 0.04). A tendency towards decreasing snack frequency with increasing restrained eating was observed (β = -0.03, 95% CI -0.07; 0.00, p = 0.07). No association was found between changes in restrained eating and concurrent changes in morning energy intake. Conclusion We found indications for cross-sectional and

    The research explored (1) the relationships between self-reported eating style (restraint, emotional and external eating) and dietary intake and (2) emotional eater status as a moderator of food intake when emotional, in a morbidly obese population. A sample of 57 obese participants (BMI: M = 51.84, SD = 8.66) completed a five-day food diary together with a reflective diary, which assessed eating style and positive and negative affect daily. A dietician-scored food pyramid analysis of intake. Restraint eating was the only predictor (negative) of overall food intake and the variable most strongly associated with the consumption of top-shelf foods. Emotional and external eating were unrelated to food intake. Emotional eater status did not moderate food intake in response to positive and negative mood states. The findings indicated largely analogous relationships between eating style and dietary intake in this obese sample compared with previous results from healthy populations. The lack of predictive validity for emotional eating scales (when emotional) raises questions over people's ability to adequately assess their eating style and consequently, the overall validity of emotional eater scales.

    Summary Various types of wound care products abound for the treatment of burn injuries. Most of these products are rather expensive and beyond the means of many patients in poorer countries. This poses a challenge to burn care workers in these environments and calls for the adoption of practical solutions with the use of less expensive and readily available alternatives. The aim of this study is to review the outcome of our burn patients managed with topical silver sulphadiazine dressing in terms of time to wound healing and length of hospital stay. Consecutive burn patients admitted over a four year period were included in the study. The patients were resuscitated along standard protocols and their wounds were dressed daily with dermazin. The demographic and clinical characteristics of the patients were retrieved and analyzed using the SPSS version 16. The primary outcome measure for the study was the time to complete re-epithelialization of the wounds and discharge of the patients. 144 patients with a M: F ratio of 2.3: 1 were managed during the period. The age range was 4 months to 81.9 years with a median age of 26 years. The TBSA range was 1 to 99% with a median of 28.5%. The mean duration from time of injury to wound healing was 21.5 days with a median of 17 days. Open burn wound dressing with silver sulphadiazine offers a satisfactory outcome and should be considered for burn dressing in low resource settings. PMID:24563642

    People often view themselves more favorably than others, displaying unrealistic optimism. In the present study, we investigated whether people perceive their reasons for eating as better than those of others. Furthermore, we investigated which mechanisms of inaccuracy might underlie a possible bias when perceiving why people eat what they eat. In Study 1, 117 participants rated the social desirability of eating motives. In Study 2, 772 participants provided information on their own and others’ motives for eating behavior. In Study 1, particularly desirable motives were eating because of hunger, health reasons, and liking. Particularly undesirable motives were eating to make a good impression, to comply with social norms, and to regulate negative affect. Study 2 revealed that for socially desirable motives, participants perceived their own motives to be stronger; for undesirable motives, the opposite pattern emerged, with others being attributed stronger motives. Moreover, the perception of others’ emotional and social motives varied with participants’ own healthy eating behavior. Since the perception of eating motives of others should be independent of one’s own behavior, this pattern of results indicates a relative inaccuracy in the perception of others’ eating motives. In conclusion, there is evidence for unrealistic optimism in eating motives. For social and emotional motives, this self-favoring view seems to be driven by a relatively inaccurate perception of others. PMID:28261140

    A limited literature suggests an association between maternal eating disorders and child feeding difficulties, and notes maternal concern about inadvertently transmitting eating disorders. Thus, parents may be an important target for eating-disorder research to guide the development of clinical programs. The current study examined differences in child eating-disorder behaviors and parental feeding practices between a sample of parents (42 fathers, 130 mothers) exhibiting core features of anorexia nervosa, bulimia nervosa, binge-eating disorder, or purging disorder, and a matched sample of parents (n=172) reporting no eating-disorder characteristics. Parents with eating-disorder psychopathology were significantly more likely than parents without eating-disorder characteristics to report child binge-eating and compulsive exercise. Parents with eating-disorder psychopathology reported greater perceived feeding responsibility, greater concern about their child's weight, and more monitoring of their child's eating than parents without eating-disorder characteristics; however, they did not differ significantly in restriction of their child's diet and pressure-to-eat. Child body mass index z-scores did not differ between parents with versus without eating-disorder characteristics. Our findings suggest some important differences between parents with and without core eating-disorder psychopathology, which could augment clinical interventions for patients with eating disorders who are parents, or could guide pediatric eating-disorder prevention efforts. However, because our study was cross-sectional, findings could indicate increased awareness of or sensitivity to eating-disorder behaviors rather than a psychosocial cause of those behaviors. Longitudinal research and controlled trials examining prevention and intervention can clarify and address these clinical concerns. Copyright © 2016 Elsevier Inc. All rights reserved.

    Purpose: This study investigated the superficial dose enhancement in the application of topical agents, clinical materials (thermal mask and bolus) and dressings in megavoltage photon beam radiotherapy. Different topical skin agents, clinical materials and dressings were evaluated and compared for their skin dosimetric impacts on the patients during radiation treatment. Methods: Superficial dose enhancements, or percentage doses with and without the studying materials, were measured using the 6 MV (Field size = 10×10 cm{sup 2}) photon beams produced by a Varian TrueBeam linear accelerator. Twelve topical agents, five dressings (dry and wet conditions) and three clinical materials were studied. Amore » solid water phantom was used with a MOSFET dose detector (TN-1002RD, Thomson and Nielsen Electronic, Ottawa, Ontario, Canada) located under a 1-mm PMMA slab to measure the skin dose. The distance between the radiation source and phantom surface was set to 100 cm in all measurements. The topical agents were distributed evenly with 1.5 mm thickness using our specific sample holder on the phantom surface. Extrapolations were made of 0.5 mm thickness for the agents to provide meaningful clinical value. Results: By comparing surface doses without studying materials, it is found that no topical agents had superficial dose enhancement higher than the clinical materials namely, thermoplastic mask (128%), 5-mm Superflab™ bolus (158%) and 10-mm Superflab™ bolus (171%) regarding the same thickness. Superficial dose enhancement of dry dressing did not exceed 110.5%, while wet dressings produced higher dose enhancements (133% for wet Mepilex lite and 141% for wet Mepilex Ag transfer). Conclusion: It is concluded that the evaluated topical agents and dry dressings did not increase the superficial dose to a concerning level, even using excessive thickness in every fraction of radiation treatment. Wet dressings were found producing the bolus effect, but was still substantially

    Chitosan dressing might be promising to promote the recovery following endoscopic sinus surgery (ESS). However, the results remain controversial. We conducted a systematic review and meta-analysis to explore the influence of chitosan dressing on ESS. PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of chitosan dressing on endoscopic sinus surgery were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcomes were synechia and hemostasis. Meta-analysis was performed using random-effect model. Four RCTs involving 268 patients were included in the meta-analysis. Overall following ESS, compared with control intervention, chitosan dressing significantly reduced synechia (RR = 0.25; 95% CI 0.13-0.49; P < 0.0001) and promoted hemostasis (RR = 1.70; 95% CI 1.37-2.11; P < 0.00001), but showed no impact on granulations (RR = 1.18; 95% CI 0.72-1.95; P = 0.52), mucosal edema (RR = 0.88; 95% CI 0.60-1.29; P = 0.51), crusting (RR = 0.85; 95% CI 0.48-1.53; P = 0.60), and infection (RR = 0.88; 95% CI 0.51-1.52; P = 0.64). Compared to control intervention, chitosan dressing could significantly decrease edema and improve hemostasis, but had no effect on granulations, mucosal edema, crusting and infection.

    Objective To model the cost-effectiveness impact of routine use of an antimicrobial chlorhexidine gluconate-containing securement dressing compared to non-antimicrobial transparent dressings for the protection of central vascular lines in intensive care unit patients. Design This study uses a novel health economic model to estimate the cost-effectiveness of using the chlorhexidine gluconate dressing versus transparent dressings in a French intensive care unit scenario. The 30-day time non-homogeneous markovian model comprises eight health states. The probabilities of events derive from a multicentre (12 French intensive care units) randomized controlled trial. 1,000 Monte Carlo simulations of 1,000 patients per dressing strategy are used for probabilistic sensitivity analysis and 95% confidence intervals calculations. The outcome is the number of catheter-related bloodstream infections avoided. Costs of intensive care unit stay are based on a recent French multicentre study and the cost-effectiveness criterion is the cost per catheter-related bloodstream infections avoided. The incremental net monetary benefit per patient is also estimated. Patients 1000 patients per group simulated based on the source randomized controlled trial involving 1,879 adults expected to require intravascular catheterization for 48 hours. Intervention Chlorhexidine Gluconate-containing securement dressing compared to non-antimicrobial transparent dressings. Results The chlorhexidine gluconate dressing prevents 11.8 infections /1,000 patients (95% confidence interval: [3.85; 19.64]) with a number needed to treat of 85 patients. The mean cost difference per patient of €141 is not statistically significant (95% confidence interval: [€-975; €1,258]).

    Aim of the study was to compare the microstructural eating behavior of obese patients with and without binge eating disorder (BED) after stress induction in laboratory. Seventy-one female subjects were investigated (mean BMI 36.9). Thirty-five fulfilled criteria for BED. A 2×2 factorial design with repeated measurement (stress vs. no stress) on the second factor was applied. Stress was induced by the Trier Social Stress Test (TSST) and chocolate pudding served as laboratory food. Variables of eating behavior were measured by a universal eating monitor (UEM). Only in participants with BED stress was associated with an increase in the initial eating rate and a diminished deceleration of eating at the end of the meal. Generally, BED subjects ate with larger size of spoonfuls during the laboratory meal than non BED controls. The eating behavior of obese patients with binge eating disorder seems to be significantly affected by stress. The stress-induced eating behavior of BED patients is characterized by a stronger motivation to eat (indicated by a fast initial eating rate) as well as by a lack of satiety perception (indicated by less deceleration of eating rate).

    2016-01-01

    Objective A limited literature suggests an association between maternal eating disorders and child feeding difficulties, and notes maternal concern about inadvertently transmitting eating disorders. Thus, parents may be an important target for eating-disorder research to guide the development of clinical programs. Methods The current study examined differences in child eating-disorder behaviors and parental feeding practices between a sample of parents (42 fathers, 130 mothers) exhibiting core features of anorexia nervosa, bulimia nervosa, binge-eating disorder, or purging disorder, and a matched sample of parents (n=172) reporting no eating-disorder characteristics. Results Parents with eating-disorder psychopathology were significantly more likely than parents without eating-disorder characteristics to report child binge-eating and compulsive exercise. Parents with eating-disorder psychopathology reported greater perceived feeding responsibility, greater concern about their child’s weight, and more monitoring of their child’s eating than parents without eating-disorder characteristics; however, they did not differ significantly in restriction of their child’s diet and pressure-to-eat. Child body mass index z-scores did not differ between parents with versus without eating-disorder characteristics. Conclusion Our findings suggest some important differences between parents with and without core eating-disorder psychopathology, which could augment clinical interventions for patients with eating disorders who are parents, or could guide pediatric eating-disorder prevention efforts. However, because our study was cross-sectional, findings could indicate increased awareness of or sensitivity to eating-disorder behaviors rather than a psychosocial cause of those behaviors. Longitudinal research and controlled trials examining prevention and intervention can clarify and address these clinical concerns. PMID:27302549

    This study used balance theory to illuminate the relations of eating-related attitudinal consistency between self and friends to psychological well-being and eating behaviors. It was hypothesized that attitudinal inconsistency, relative to consistency, would predict lower well-being and poorer eating habits. A population-based sample of 2287 young adults participating in Project EAT-III (Eating Among Teens and Young Adults) completed measures of psychological well-being, eating behaviors, and eating-related attitudes from the standpoint of self and friends. Of participants who cared about healthy eating, those who perceived that their friends did not care about healthy eating had lower well-being and less-healthy eating behaviors (fewer fruits and vegetables and more sugary beverages per day) than those who perceived that their friends cared about healthy eating. Conversely, among participants who did not care about healthy eating, those who perceived that their friends cared about healthy eating had lower well-being and less-healthy eating behaviors (more snacks per day) than those who perceived that their friends did not care about healthy eating. In accord with balance theory, young adults who perceived inconsistent eating attitudes between themselves and their friends had lower psychological well-being and generally less-healthy eating behaviors than people who perceived consistent eating attitudes.

    2013-01-01

    Background: Numerous dressings for split-thickness skin graft donor sites are commercially available with no conclusive evidence-based consensus regarding the optimal dressing choice. This study was conducted to identify which of 5 commonly used materials promotes wound healing most effectively for use on split-thickness donor sites in comparison with our standard dressing, Xeroform (petrolatum gauze). Methods: Twenty-four partial-thickness wounds were created on the backs of 4 pigs using a dermatome. Wounds (n = 4 per dressing type per pig) were treated with Xeroform, Opsite (polyurethane film), Kaltostat ( calcium sodium alginate), DuoDERM (hydrocolloid), Aquacel (hydrofiber), and Mepilex (silicone foam). Full-thickness skin samples were excised at 3 or 5 days and evaluated histologically for reepithelialization and inflammation. Comparisons also included incidence of infection, ease of use, and cost analyses. Results: DuoDERM elicited the greatest percent reepithelialization (81%) and Mepilex the lowest (33%) after 3 days (P = 0.004). All dressings demonstrated complete reepithelialization except Mepilex (85%) at 5 days. There were no infections and inflammation was mild among all treatments. Mepilex was easiest to use, whereas Aquacel, Kaltostat, and Opsite were most difficult (P = 0.03). Xeroform was most cost-effective and Aquacel most expensive. Combined scoring revealed DuoDERM = Xeroform > Opsite = Mepilex > Kaltostat > Aquacel. Conclusions: DuoDERM and Xeroform were most effective overall. DuoDERM tended to outperform all dressings in reepithelialization at 3 days, while Xeroform was least expensive, easy to use, and demonstrated rapid reepithelialization. These findings suggest that Xeroform may be preferred for use on large donor-site areas. DuoDERM may be more appropriate for small donor sites when healing time is a priority. PMID:25289278

  3. Does the Use of Clean or Sterile Dressing Technique Affect the Incidence of Wound Infection?

    PubMed

    Kent, Dea J; Scardillo, Jody N; Dale, Barbara; Pike, Caitlin

    The purpose of this article is to examine the evidence and provide recommendations for the use of clean or sterile dressing technique with dressing application to prevent wound infection. In all persons with acute or chronic wounds, does the use of clean or sterile dressing technique affect incidence of wound infection? A search of the literature was performed by a trained university librarian, which resulted in 473 articles that examined any age group that dealt with application of a wound dressing using either sterile or nonsterile technique. A systematic approach was used to review titles, abstracts, and text, yielding 4 studies that met inclusion criteria. Strength of the evidence was rated using rating methodology from Essential Evidence Plus: Levels of Evidence and Oxford Center for Evidence-Based Medicine, adapted by Gray and colleagues. Johns Hopkins Nursing Evidence-Based Practice Nursing Research Appraisal Tool was used to rate the quality of the evidence. All 4 studies reported no significant difference in the rate of wound infection when using either clean or sterile technique with dressing application. The strength of the evidence for the identified studies was identified as level 2 (1 level A, 3 level B). The study sizes were variable, and the wounds included do not represent the continuum of wounds clinically encountered across the board. Evidence indicates that the use of clean technique for acute wound care is a clinically effective intervention that does not affect the incidence of infection. There is no recommendation that can be made regarding type of dressing technique for a chronic wound due to the lack of evidence in the literature.

    We explored differences in adolescents' eating habits, perceptions, and dietary intakes by food security status. As part of Project EAT (Eating Among Teens), we surveyed 4746 multiethnic middle and high school students in 31 primarily urban schools in the Minneapolis-St. Paul, Minnesota, area during the 1998-1999 academic year. Participants completed in-class surveys. We used multiple regression analysis to characterize associations between behaviors, perceptions, nutritional intake, and food security status. Compared with food-secure youths, food-insecure youths were more likely to perceive that eating healthfully was inconvenient and that healthy food did not taste good. Additionally, food-insecure youths reported eating more fast food but fewer family meals and breakfasts per week than did youths who were food secure. Food-insecure and food-secure youths perceived similar benefits from eating healthfully (P = .75). Compared with those who were food secure, food-insecure youths had higher fat intakes (P < .01). Food-insecure youths were more likely to have a body mass index above the 95th percentile. The eating patterns of food-insecure adolescents differ in important ways from the eating patterns of those who are food secure. Policies and interventions focusing on improving the foods that these youths eat deserve further examination.

  5. The audience eats more if a movie character keeps eating: An unconscious mechanism for media influence on eating behaviors.

    2017-01-01

    Media's presentation of eating is an important source of influence on viewers' eating goals and behaviors. Drawing on recent research indicating that whether a story character continues to pursue a goal or completes a goal can unconsciously influence an audience member's goals, a scene from a popular movie comedy was manipulated to end with a character continuing to eat (goal ongoing) or completed eating (goal completed). Participants (N = 147) were randomly assigned to a goal status condition. As a reward, after viewing the movie clip viewers were offered two types of snacks: ChexMix and M&M's, in various size portions. Viewers ate more food after watching the characters continue to eat compared to watching the characters complete eating, but only among those manipulated to identify with a character. Viewers were more likely to choose savory food after viewing the ongoing eating scenes, but sweet dessert-like food after viewing the completed eating scenes. The results extend the notion of media influence on unconscious goal contagion and satiation to movie eating, and raise the possibility that completing a goal can activate a logically subsequent goal. Implications for understanding media influence on eating and other health behaviors are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The dressing effects on the occurrence scattering time for the dust-dust interaction are investigated in a complex plasma. The first-order eikonal analysis is applied to obtain the scattering amplitude and the occurrence scattering time for the dust-dust interaction. The result shows that dressing effect enhances the retardation phenomena of the occurrence scattering time in the forward scattering domain. It is shown that the oscillatory behavior of the scaled occurrence scattering time is getting more significant with an increase of the Debye length. It is also found that the retardation domain of the occurrence scattering time increases with a decrease of the Debye length. The variation of the occurrence scattering time retardation and advance due to the dressing effect is also discussed.

  13. Relationship between work-family conflict and unhealthy eating: Does eating style matter?

    PubMed

    Shukri, Madihah; Jones, Fiona; Conner, Mark

    2018-04-01

    There is increasing evidence to suggest that work-family conflict is implicated in poor eating patterns. Yet, the underlying mechanism remains unexplored. The objectives of the present study were to demonstrate the interplay between work-family conflict, eating style, and unhealthy eating, and to test whether body mass index (BMI) and its interactions further explicate the relationships. In this study, 586 Malaysian adults (normal weight n = 437, overweight n = 149) completed a questionnaire, which included demographic variables, work-family scales, eating style measures, namely, restrained, emotional or external eating and reported food intake. As hypothesized, results showed that family-to-work conflict (FWC), emotional eating and external eating were positively related to unhealthy food consumption. In addition, emotional eating was found to moderate the impact of FCW on eating. These findings are consistent with research that has revealed emotional eating can indeed increase the positive association between stress such as conflict and unhealthy food choices. However, we found no clear support for the interactive effects of BMI. Our research builds on the findings of existing research as it demonstrates the role of eating style in explaining the association between work-family conflict and unhealthy eating. This conclusion has potential implications for appropriate interventions and calls for the enhancement of various policies to tackle obesity and other health problems. Copyright © 2018 Elsevier Ltd.

    2015-07-01

    Research on eating behaviour has identified several potentially relevant eating-related traits captured by different questionnaires. Often, these questionnaires predict Body Mass Index (BMI), but the relationship between them has not been explicitly studied. We studied the unity and diversity of questionnaires capturing five common eating-related traits: Power of Food, Eating Impulsivity, emotional eating, Disinhibition, and binge eating in women from Estonia (n = 740) and Canada (n = 456). Using bifactor analysis, we showed that a) these questionnaires are largely explained by a single factor, and b) relative to this shared factor, only some questionnaires offered additional variance in predicting BMI. Hence, these questionnaires seemed to characterise a common factor, which we label Uncontrolled Eating. Item Response Theory techniques were then applied to demonstrate that c) within this common factor, the questionnaires could be placed on a continuum of Uncontrolled Eating. That is, Eating Impulsivity focused on the milder degree, Power of Food Scale, emotional eating scales, and Disinhibition on intermediate degrees, and the Binge Eating Scale on the most severe degrees of Uncontrolled Eating. In sum, evidence from two samples showed that questionnaires capturing five common BMI-related traits largely reflected the same underlying latent trait - Uncontrolled Eating. In Estonia, some questionnaires focused on different severities of this common construct, supporting a continuum model of Uncontrolled Eating. These findings provide a starting point for developing better questionnaires of the neurobehavioural correlates of obesity, and provide a unifying perspective from which to view the existing literature.

    Chitosan oleate was previously proposed to encapsulate in nanocarriers some poorly soluble molecules aimed to wound therapy, such as the anti-infective silver sulfadiazine, and the antioxidant α tocopherol. Because nanocarriers need a suitable formulation to be administered to wounds, in the present paper, these previously developed nanocarriers were loaded into freeze dried dressings based on chitosan glutamate. These were proposed as bioactive dressings aimed to support the application to wounds of platelet lysate, a hemoderivative rich in growth factors. The dressings were characterized for hydration capacity, morphological aspect, and rheological and mechanical behavior. Although chitosan oleate nanocarriers clearly decreased the mechanical properties of dressings, these remained compatible with handling and application to wounds. Preliminary studies in vitro on fibroblast cell cultures demonstrated good compatibility of platelet lysate with nanocarriers and bioactive dressings. An in vivo study on a murine wound model showed an accelerating wound healing effect for the bioactive dressing and its suitability as support of the platelet lysate application to wounds.

    The use of negative-pressure-wound-therapy (NPWT) is associated with improved outcomes in smaller burns. We report our experience using extra-large (XL) NPWT dressings to treat ≥15% total body surface area (TBSA) burned and describe our technique and early outcomes. We also provide NPWT exudate volume for predictive fluid resuscitation in these critically ill patients. We retrospectively reviewed patients treated with XL-NPWT from 2012 to 2014. Following excision/grafting, graft and donor sites were sealed with a layered NPWT dressing. We documented wound size, dressing size, NPWT outputs, graft take, wound infections, and length of stay (LOS). Mean NPWT exudate volume per %TBSA per day was calculated. Twelve burn patients (mean TBSA burned 30%, range 15-60%) were treated with XL-NPWT (dressing TBSA burned and skin graft donor sites range 17-44%). Average graft take was 97%. No wound infections occurred. Two patients had burns ≥50% TBSA and their LOS was reduced compared to ABA averages. XL-NPWT outputs peaked at day 1 after grafting followed by a steady decline until dressings were removed. Average XL-NPWT dressing output during the first 5 days was 101±66mL/%BSA covered per day. 2 patients developed acute kidney injury. The use of XL-NPWT to treat extensive burns is feasible with attention to application technique. NPWT dressings appear to improve graft take, and to decrease risk of infection, LOS, and pain and anxiety associated with wound care. Measured fluid losses can improve patient care in future applications of NPWT to large burn wounds. Copyright © 2015 Elsevier Ltd and ISBI. All rights reserved.

    Conversational robots and agents are being designed for educational and/or persuasive tasks, e.g., health or fitness coaching. To pursue such tasks over a long time, they will need a complex model of the strategic goal, a variety of strategies to implement it in interaction, and the capability of strategic talk. Strategic talk is incipient ongoing conversation in which at least one participant has the objective of changing the other participant's attitudes or goals. The paper is based on the observation that strategic talk can stretch over considerable periods of time and a number of conversational segments. Film dialogues are taken as a source to develop a model of the strategic talk of mentor characters. A corpus of film mentor utterances is annotated on the basis of the model, and the data are interpreted to arrive at insights into mentor behavior, especially into the realization and sequencing of strategies.

    Moist wounds were known to heal more rapidly than dry wounds. Hydrogel wound dressings were suitable for the moist wound healing because of their hyperhydrous structure. Chitosan was a strong candidate as a base material for hydrogel wound dressings because the polymer had excellent biological properties that promoted wound healing. We previously developed physically-crosslinked chitosan cryogels, which were prepared solely by freeze-thawing of a chitosan-gluconic acid conjugate (CG) aqueous solution, for wound treatment. The CG cryogels were disinfected by immersing in 70% ethanol before applying to wounds in our previous study. In the present study, we examined the influence of autoclave sterilization (121°C, 20 min) on the characteristics of CG cryogel because complete sterilization was one of the fundamental requirements for medical devices. We found that optimum value of gluconic acid content of CG, defined as the number of the incorporated gluconic acid units per 100 glucosamine units of chitosan, was 11 for autoclaving. An increased crosslinking level of CG cryogel on autoclaving enhanced resistance of the gels to enzymatic degradation. Furthermore, the autoclaved CG cryogels retained favorable biological properties of the pre-autoclaved CG cryogels in that they showed the same hemostatic activity and efficacy in repairing full-thickness skin wounds as the pre-autoclaved CG cryogels. These results showed the great potential of autoclavable CG cryogels as a practical wound dressing. Copyright © 2017 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    Background There is growing interest and debate about whether an addictive process contributes to problematic eating outcomes, such as obesity. Craving is a core component of addiction, but there has been little research on the relationship between addictive-like eating, craving, and eating-related concerns. In the current study, we examine the effect of both overall food craving and craving for different types of food on the relationship between addictive-like eating symptoms and elevated body mass index (BMI) and binge eating episodes. Methods In a community sample (n = 283), we conducted analyses to examine whether overall craving mediated the association between addictive-like eating and elevated BMI, as well as binge eating frequency. We also ran separate mediational models examining the indirect effect of cravings for sweets, fats, carbohydrates, and fast food fats on these same associations. Results Overall food craving was a significant partial mediator in the relationships between addictive-like eating and both elevated BMI and binge eating episodes. Cravings for sweets and other carbohydrates significantly mediated the relationship between addictive-like eating and binge eating episodes, while cravings for fats significantly mediated the relationship between addictive-like eating and elevated BMI. Conclusions Craving appears to be an important component in the pathway between addictive-like eating and problematic eating outcomes. The current results highlight the importance of further evaluating the role of an addictive process in problematic eating behaviors and potentially targeting food cravings in intervention approaches.

    Given that traditional interventions promoting the adoption of a healthy diet are having limited impacts on the population's food choices and eating behaviours, researchers and health practitioners could explore alternative strategies such as the use of eating pleasure to promote healthy eating. To inform future interventions using this approach, this study aimed to explore how a sample of Quebecers perceives and defines eating pleasure and healthy eating. Specific objectives were to verify what commonalities can be found between their definitions of eating pleasure and healthy eating, and what differences can be observed in their answers based on their sex and body mass index (BMI). Twelve focus groups were conducted in Quebec City, Canada, among women and men with a normal weight and with obesity (n = 92). Verbatim transcripts were double-coded using NVivo10. Participants mostly defined eating pleasure through food characteristics related to sensory qualities and psychosocial contexts. In contrast, they mostly mentioned food characteristics related to nutritional quality and ways to regulate eating behaviours to define healthy eating. Most salient perceptions were similar among subgroups based on sex or BMI. Results showed that in participants' perceptions, the concepts of eating pleasure and healthy eating were different, but appeared to be mostly compatible, which makes the integration of eating pleasure a promising avenue for interventions promoting healthy eating.

    Collagen was isolated from the chrome containing leather waste (CCLW) which is a major solid waste in leather industry. Composite films were made using sago starch (SG), soya protein (SY), and collagen (C) and were cross linked with glutaraldehyde (G).The films prepared were characterized for their physico chemical properties like tensile strength, infrared spectra, thermogravimetric analysis, surface morphology, and water absorption studies. Better mechanical properties and surface morphology were observed for SG-SY-G-C films compared to other films prepared using collagen. The composite films prepared were used as wound dressing material on the experimental wounds of rats and healing pattern was evaluated using planimetric, biochemical, and histopathological studies. These studies have revealed better wound healing capacity of SG-SY-G-C film and utilization of CCLW in the preparation of value added product like wound dressing material.

    Israeli youth lead 27 western countries in dieting. The prevalence of eating disorders has been rising in the last 30 years, causing social problems and medical complications. To examine the prevalence of eating disorders among high school students in a region in northern Israel (Misgav) and to examine the relationship between the parents' employment status and the subject's eating disorder. A structured questionnaire was administered to collect demographic data. The short version of the Eating Attitudes Test (EAT-26) was used to evaluate the subject's attitudes toward and preoccupation with food, dieting, eating, physical appearance, and personal control over eating. Of 360 students approached, 283 (78%) completed the self-report EAT-26. One of every 5 females and one in every 20 males had an abnormal eating attitude. The rate of pathologic EAT-26 results, 20.8%, falls within the high range of similar community-based samples of female adolescents. There were no differences in EAT-26 score between students with an employed or unemployed mother; however, there was a trend for higher EAT-26 scores among those whose father was unemployed (21.4% vs. 12.7%, chi2 = 0.14). The findings support our hypothesis of a relatively high rate of abnormal eating attitudes (as reflected by high EAT-26 score) in this population. Another possible risk factor is having an unemployed father, which warrants further research and attention. Our next step is to introduce an intervention program in the school and to study its effect.

    The objective was to compare eating attitudes, conceptualized as beliefs, thoughts, feelings, behaviors and relationship with food, of anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED) patients and a group of obese (OBS) without eating disorders (ED). Female patients from an Eating Disorder (ED) Unit with AN (n=42), BN (n=52) and BED (n=53) and from an obesity service (n=37) in Brazil answered the Disordered Eating Attitude Scale (DEAS) which evaluate eating attitudes with 5 subscales: relationship with food, concerns about food and weight gain, restrictive and compensatory practices, feelings toward eating, and idea of normal eating. OBS patients were recruited among those without ED symptoms according to the Binge Eating Scale and the Questionnaire on Eating and Weight Patterns. ANOVA was used to compare body mass index and age between groups. Bonferroni test was used to analyze multiple comparisons among groups. AN and BN patients presented more dysfunctional eating attitudes and OBS patients less dysfunctional (p<0.001). For DEAS total score, AN and BN patients were similar and all other were different (p<0.001). Similarities suggested between BN and BED were true just for the "Relationship with food" and "Idea of normal eating." BED patients were worst than OBS for "Relationship with food" and as dysfunctional as AN patients - besides their behavior could be considered the opposite. Differences and similarities support a therapeutic individualized approach for ED and obese patients, call attention for the theoretical differences between obesity and ED, and suggest more research focused on eating attitudes.

    2014-01-01

    Venous leg ulcers affect millions of patients worldwide and are a tremendous financial burden on our healthcare system. The hallmark of venous disease of the lower extremities is venous hypertension, and compression is the current mainstay of treatment. However, many patients are noncompliant, in part because of the complexity of the dressings and the difficulties with application and removal. The aim of our study was to determine an effective compression dressing regimen for patients with venous leg ulcers who require changing the ulcer primary dressing twice daily. We used two layers of a latex free tubular elastic bandage for compression. The primary endpoint of our study was increased wound healing rate and our secondary endpoint was complete wound closure. All active study subjects had positive healing rates at week 4 and week 8. Two subjects achieved complete wound closure by week 8. We conclude that compression with a latex-free tubular elastic bandage can be safely used in patients with venous leg ulcers requiring frequent dressing changes. This type of compression allows for daily inspection of wounds, dressing changes at home, flexibility in the context of clinical trials, and is a compromise for patients that are intolerant to compression dressings.

    Health experts advise and expect patients to eat healthily after bariatric surgery. For patients, difficulties with eating might have been a long-standing, problematic part of life—a part that is not necessarily healed by surgery. Empirical research on patients’ experiences of eating practices after bariatric surgery is lacking. Aiming to contribute to the development of clinical practice, we explored meanings attached to eating in the long term and sought descriptions of change and bodily sensations. We interviewed 14 patients at least 5 years after bariatric surgery. The surgical restriction forced changes in the way patients sensed their own body in eating, but the uncertainty related to maintaining weight loss in the long term remained. Meanings attached to eating transcended food as choices situated in a nourishment and health perspective, and were not necessarily changed. Eating was an existential and embodied practice, which remained an ambiguous and sensitive matter after surgery. PMID:25156217

    ABSTRACT Conversational robots and agents are being designed for educational and/or persuasive tasks, e.g., health or fitness coaching. To pursue such tasks over a long time, they will need a complex model of the strategic goal, a variety of strategies to implement it in interaction, and the capability of strategic talk. Strategic talk is incipient ongoing conversation in which at least one participant has the objective of changing the other participant’s attitudes or goals. The paper is based on the observation that strategic talk can stretch over considerable periods of time and a number of conversational segments. Film dialogues are taken as a source to develop a model of the strategic talk of mentor characters. A corpus of film mentor utterances is annotated on the basis of the model, and the data are interpreted to arrive at insights into mentor behavior, especially into the realization and sequencing of strategies.

    The objective of this paper is to review the role that hedonic factors, emotions and self-regulation systems have over eating behaviours from animal models to humans. Evidence has been found to suggest that for some high-risk individuals, obesity/binge eating may develop as an impulsive reaction to negative emotions that over time becomes a compulsive habit. Animal models highlight the neural mechanisms that might underlie this process and suggest similarities with substance use disorders. Emotional difficulties and neurobiological factors have a role in the aetiology of eating and weight disorders. Precise treatments targeted at these mechanisms may be of help for people who have difficulties with compulsive overeating.

    Israel presents a unique opportunity to study the role of socio-cultural parameters in the development of mental disturbances because of the exceptional diversity of the Israeli society. In the present review, we aimed to analyse the current state of disordered eating in Israel by means of an extensive literature review. The following are the main findings of our review: The frequency of maladaptive eating among female and male Israeli Jewish adolescents is higher in comparison to many other Westernized countries. Among different Jewish sub-populations, Kibbutz women have been found until recently to show higher rates of disordered eating in comparison to other Israeli samples. Recent studies show no such difference between Kibbutz members and the general Israeli population. No clear-cut findings emerge with respect to the influence of immigration and degree of Jewish religious affiliation on the occurrence of disordered eating. In contrast, disordered eating is less prevalent in Israeli-Arabs compared with Israeli-Jews. Moreover, diverse Israeli-Arab groups show different rates of disordered eating. We discuss the high rate of disordered eating in Israeli youth in light of Israel being a culture in transition that is constantly exposed to the risk of terrorism. The changes in the rates of disordered eating in the Kibbutzim are discussed in light of the dramatic societal changes occurring in these communities within a relatively brief period of time. The low rates of disordered eating in Israeli-Arabs reflect the traditional non-Westernized characteristics of their society, whereas the differences between diverse Arab sub-populations depend upon the degree of exposure to Westernized influences and the presence of conflicts between modern and traditional values.

    Food rejection behaviors such as picky eating are of concern for many parents and attempts to increase healthy food intake can cause distress at mealtimes. An important limitation in most of the picky eating studies is that they cover few characteristics of picky eating behaviors and use limited measures of food intake. The objective of this study was to explore the associations between picky eating, child eating characteristics, and food intake among toddlers 12-47.9 months old (n = 2371) using data from the 2008 Feeding Infants and Toddlers Study (FITS). Logistic regression was used to examine associations between demographic and feeding characteristics and picky eater status. Differences in food group intake between picky and non-picky eaters were analyzed. Picky eaters were more likely to be neophobic, texture resistant, and to eat only favorite foods, In addition, the parents of picky eaters tend to offer new food a greater number of times than those of non-picky eaters before deciding that the child does not like it. Picky eaters showed significant lower intakes of eggs, burritos/tacos/enchiladas/nachos and sandwiches than non-picky eaters. Picky eaters consumed fewer vegetables from the "other vegetables" category and less raw vegetables than non-picky eaters. Neophobia, eating only favorite foods and difficulties with texture are all important characteristics of picky eaters which need to be integrated in studies measuring picky eating behaviors. Food intake of picky eaters differs only slightly from non-picky eaters. Because picky eating is a major parental concern, feeding strategies and advice related to the relevant characteristics of picky eating behavior need to be developed and assessed for their effectiveness.

  15. Honey: A Biologic Wound Dressing.

    PubMed

    Molan, Peter; Rhodes, Tanya

    2015-06-01

    Honey has been used as a wound dressing for thousands of years, but only in more recent times has a scientific explanation become available for its effectiveness. It is now realized that honey is a biologic wound dressing with multiple bioactivities that work in concert to expedite the healing process. The physical properties of honey also expedite the healing process: its acidity increases the release of oxygen from hemoglobin thereby making the wound environment less favorable for the activity of destructive proteases, and the high osmolarity of honey draws fluid out of the wound bed to create an outflow of lymph as occurs with negative pressure wound therapy. Honey has a broad-spectrum antibacterial activity, but there is much variation in potency between different honeys. There are 2 types of antibacterial activity. In most honeys the activity is due to hydrogen peroxide, but much of this is inactivated by the enzyme catalase that is present in blood, serum, and wound tissues. In manuka honey, the activity is due to methylglyoxal which is not inactivated. The manuka honey used in wound-care products can withstand dilution with substantial amounts of wound exudate and still maintain enough activity to inhibit the growth of bacteria. There is good evidence for honey also having bioactivities that stimulate the immune response (thus promoting the growth of tissues for wound repair), suppress inflammation, and bring about rapid autolytic debridement. There is clinical evidence for these actions, and research is providing scientific explanations for them.

    The night eating syndrome (NES) consists of evening hyperphagia and/or nocturnal eating and has been associated with depressed mood, that worsens in the evening. However, it is not consistently related to elevated BMI. The present study was conducted to examine whether a relationship exists between NES and emotional, external, and restrained eating. BMI and sleep quality were also obtained. A sample of 246 students completed the Night Eating Diagnostic Questionnaire (NEDQ), Night Eating Syndrome History and Inventory (NESHI), Sleep Quality Index (SQI), and Dutch Eating Behavior Questionnaire (DEBQ), containing subscales for emotional, external, and restrained eating. They also provided demographic information, including height and weight. Participants were grouped by severity of NES features using the NEDQ and NESHI: normal, mild night eater, moderate night eater, and full night eater syndrome. MANOVA was used to compare DEBQ subscores for the groups; those in the full syndrome category had significantly higher emotional eating scores and external eating scores than those in the normal and mild categories. There was no difference in restrained eating between the normal and full syndrome groups. Those with moderate and full syndrome NES symptoms also reported significantly lower sleep quality. No significant relationship was found between NES and BMI. The results show that NES is associated with more eating in response to negative mood and in response to food cues. PMID:22664397

The type of dressing could contribute to the incidence of phlebitis, infiltration and accidental removals but the results of the studies are contrasting and samples are limited. To compare the effectiveness of a transparent polyurethane sterile dressing on the rate of phlebitis associated to peripheral venous catheter (PVC) vs a non sterile sticking plaster in use in current practice (standard dressing). Randomized controlled trial. Participants. 1061 PVCs (703 patients, adults and children) at a research orthopedic hospital in the north of Italy; 540 PVCs allocated to receive the sterile and 521 the standard dressing. 96 PVCs were excluded for phlebitis, 48 (9.6%) in the sterile and 48 (10.1%) in the standard dressing group, RR 0.96 (95%CI 0.697 - 1.335). Accidental removal of the PVCs was more frequent with the sterile dressing (9.6% vs 6.3%) but the number of catheters removed without complications was larger in the standard dressing group (48.9% vs 54.9% P=0.0503). Eighty-five PVCs were replaced for detachment of the dressing (50, 9.2% sterile and 35, 6.7% standard dressing). The cheapest transparent sterile dressing costs 32 cents while the standard 9 cents. A sticking non sterile plasters is not influential on the rate of phlebitis and ensures an good fix of the PVC compared the transparent sterile dressing to of polyurethane film.

    Wound moisture is known to be a key parameter to ensure optimum healing conditions in wound care. This study tests the moisture content of wounds in normal practice in order to observe the moisture condition of the wound at the point of dressing change. This study is also the first large-scale observational study that investigates wound moisture status at dressing change. The WoundSense sensor is a commercially available moisture sensor which sits directly on the wound in order to find the moisture status of the wound without disturbing or removing the dressing. The results show that of the 588 dressing changes recorded, 44·9% were made when the moisture reading was in the optimum moisture zone. Of the 30 patients recruited for this study, 11 patients had an optimum moisture reading for at least 50% of the measurements before dressing change. These results suggest that a large number of unnecessary dressing changes are being made. This is a significant finding of the study as it suggests that the protocols currently followed can be modified to allow fewer dressing changes and less disturbance of the healing wound bed. © 2015 The Authors.

    There were five victims of neurotoxic food poisoning from a dried dressed fish fillet in Changhua County, Taiwan, in February 2000. The toxicity of the dried dressed fish fillets was 243 mouse units per g according to a tetrodotoxin bioassay. The partially purified toxin was identified as tetrodotoxin and anhydrotetrodotoxin. The sequence of the 376-nucleotide region in the cytochrome b gene of the mitochondrial DNA exhibited the same genotype as that of the toxic puffer fish Lagocephalus lunaris. The same single restriction site for Hinfl was found in the polymerase chain reaction (PCR) products from the dried dressed fish fillet and the muscle of L. lunaris, yielding two DNA fragments of 170 and 206 bp. However, no restriction site for Hinfl was found in the PCR products from other toxic puffer fishes, including Takifugu niphobles, Takifugu oblongus, and Takifugu rubripes. Therefore, the species of the dried dressed fish fillet was identified as L. lunaris and its causative agent was identified as tetrodotoxin.

    Combining silver-based dressings with negative pressure therapy after radical excision of chronically infected breast disease is a novel application of two technologies. One patient with complex, chronic, infected breast disease underwent radical excision of the affected area and was treated early with a combination of silver-based dressings and topical negative pressure therapy. The wound was then assessed sequentially using clinical measurements of wound area and depth, pain severity scores and level of exudation. It is possible to combine accepted techniques with modern dressing technologies that result in a positive outcome. In this case, the combination of a silver-based dressing with negative pressure therapy following radical excision proved safe and was well tolerated by the patient. Full epithelisation of the wound was achieved and there was no recurrence of the infection for the duration of the treatment. © 2011 The Authors. © 2011 Blackwell Publishing Ltd and Medicalhelplines.com Inc.

    Pesticide transport from seed dressings toward subsurface tile drains is still poorly understood. We monitored the neonicotinoid insecticides imidacloprid and thiamethoxam from sugar beet seed dressings in flow-proportional drainage water samples, together with spray applications of bromide and the herbicide S-metolachlor in spring and the fungicides epoxiconazole and kresoxim-methyl in summer. Event-driven, high first concentration maxima up to 2830 and 1290 ng/L for thiamethoxam and imidacloprid, respectively, were followed by an extended period of tailing and suggested preferential flow. Nevertheless, mass recoveries declined in agreement with the degradation and sorption properties collated in the groundwater ubiquity score, following the order bromide (4.9%), thiamethoxam (1.2%), imidacloprid (0.48%), kresoxim-methyl acid (0.17%), S-metolachlor (0.032%), epoxiconazole (0.013%), and kresoxim-methyl (0.003%), and indicated increased leaching from seed dressings compared to spray applications. Measured concentrations and mass recoveries indicate that subsurface tile drains contribute to surface water contamination with neonicotinoids from seed dressings.

    Insomnia is related to an increased risk of eating disorders, while eating disorders are related to more disrupted sleep. Insomnia is also linked to poorer treatment outcomes for eating disorders. However, over the last decade, studies examining sleep and eating disorders have relied on surveys, with no objective measures of sleep for anorexia nervosa or bulimia nervosa, and only actigraphy data for binge eating disorder. Sleep disturbance is better defined for night eating syndrome, where sleep efficiency is reduced and melatonin release is delayed. Studies that include objectively measured sleep and metabolic parameters combined with psychiatric comorbidity data would help identify under what circumstances eating disorders and sleep disturbance produce an additive effect for symptom severity and for whom poor sleep would increase risk for an eating disorder. Cognitive behavior therapy for insomnia may be a helpful addition to treatment of those with both eating disorder and insomnia.

    Silicone-coated polyamide wound dressing is frequently used for the supportive treatment in patients with radiation induced skin lesions. The use of this kind of dressing during radiotherapy with high energy beams shifts the dose built-up effect towards the skin surface. Thus the dose delivered to the skin increases. The present work quantifies changes of the skin dose by a commercial silicon-coated polyamide wound dressing. The dependence on the beam quality and on different treatment techniques is investigated. Measurements were performed with photon (60Co, 6 MV, 42 MV) and electron (7 MeV, 20 MeV, 40 MeV) beams using thin LiF thermoluminescence dosimeters (TLD) in a perspex phantom. The beams were directed perpendicularly to the phantom surface. For 60Co and 6 MV photon beams the skin dose was evaluated in vivo at different beam arrangements and at a given reference dose. For 60Co, 6 MV and 42 MV photon beams wound dressing caused a dose increase on the surface of the perspex phantom by a factor of 1.65, 1.39 and 1.33 respectively. Using oblique or rotational techniques for 60Co and 6 MV photon irradiation the wound dressing increased the skin dose but less compared to perpendicular beam direction. For electron beams the skin dose is relatively high (from 84% to 92%) and an increase by a dressing has no clinical relevance (factor 1.03 to 1.05). The silicone-coated polyamide wound dressing causes no relevant skin dose increase during radiation treatment with electron beams and can be left on the skin during irradiation. During radiation treatment with photon beams like 60Co and 6 MV the protective procedure should be adapted to skin changes, in case of strong skin reactions a removal during the time of irradiation should be considered.

    The purpose of this study was to examine the reliability and validity of the Upper-body Dressing Scale (UBDS) for buttoned shirt dressing, which evaluates the learning process of new component actions of upper-body dressing in patients diagnosed with dementia and hemiparesis. This was a preliminary correlational study of concurrent validity and reliability in which 10 vascular dementia patients with hemiparesis were enrolled and assessed repeatedly by six occupational therapists by means of the UBDS and the dressing item of the Functional Independence Measure (FIM). Intraclass correlation coefficient was 0.97 for intra-rater reliability and 0.99 for inter-rater reliability. The level of correlation between UBDS score and FIM dressing item scores was -0.93. UBDS scores for paralytic hand passed into the sleeve and sleeve pulled up beyond the shoulder joint were worse than the scores for the other components of the task. The UBDS has good reliability and validity for vascular dementia patients with hemiparesis. Further research is needed to investigate the relation between UBDS score and the effect of intervention and to clarify sensitivity or responsiveness of the scale to clinical change.

    Topical antimicrobials are widely used to control wound bioburden and facilitate wound healing; however, the fine balance between antimicrobial efficacy and non-toxicity must be achieved. This study evaluated whether an anti-biofilm silver-containing wound dressing interfered with the normal healing process in non-contaminated deep partial thickness wounds. In an in-vivo porcine wound model using 2 pigs, 96 wounds were randomly assigned to 1 of 3 dressing groups: anti-biofilm silver Hydrofiber dressing (test), silver Hydrofiber dressing (control), or polyurethane film dressing (control). Wounds were investigated for 8 days, and wound biopsies (n = 4) were taken from each dressing group, per animal, on days 2, 4, 6, and 8 after wounding and evaluated using light microscopy. No statistically significant differences were observed in the rate of reepithelialisation, white blood cell infiltration, angiogenesis, or granulation tissue formation following application of the anti-biofilm silver Hydrofiber dressing versus the 2 control dressings. Overall, epithelial thickness was similar between groups. Some differences in infiltration of specific cell types were observed between groups. There were no signs of tissue necrosis, fibrosis, or fatty infiltration in any group. An anti-biofilm silver Hydrofiber wound dressing did not cause any notable interference with normal healing processes. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    The severe pain related to repeated burn dressing changes at bedside is often difficult to manage. However these dressings can be performed at bedside on spontaneously breathing non-intubated patients using powerful intravenous opioids with a quick onset and a short duration of action such as alfentanil. The purpose of this study is to demonstrate the efficacy and safety of the protocol which is used in our burn unit for pain control during burn dressing changes. Cohort study began after favorable opinion from local ethic committee has been collected. Patient's informed consent was collected. No fasting was required. Vital signs for patients were continuously monitored (non-invasive blood pressure, ECG monitoring, cutaneous oxygen saturation, respiratory rate) all over the process. Boluses of 500 (±250) mcg IV alfentanil were administered. A continuous infusion was added in case of insufficient analgesia. Adverse reactions were collected and pain intensity was measured throughout the dressing using a ten step verbal rating scale (VRS) ranging from 0 (no pain) to 10 (worst pain conceivable). 100 dressings (35 patients) were analyzed. Median age was 45 years and median burned area 10%. We observed 3 blood pressure drops, 5 oxygen desaturations (treated with stimulation without the necessity of ventilatory support) and one episode of nausea. Most of the patients (87%) were totally conscious during the dressing and 13% were awakened by verbal stimulation. Median total dose of alfentanil used was 2000μg for a median duration of 35min. Pain scores during the procedure were low or moderate (VRS mean=2.0 and maximal VRS=5). Median satisfaction collected 2h after the dressing was 10 on a ten step scale. Pain control with intravenous alfentanil alone is efficient and appears safe for most burn bedside repeated dressings in hospitalized patients. It achieves satisfactory analgesia during and after the procedure. It is now our standard analgesic method to provide repeated

    Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is an uncommon, life-threatening drug reaction. The basic findings are skin rash, multiorgan involvement, and eosinophilia. Most of the aromatic anticonvulsants, such as phenytoin, phenobarbital and carbamazepine can induce DRESS. Herein we report a 14-year-old patient with DRESS syndrome related to carbamazepine use. The patient presented with signs of involvement of the skin, lungs, liver, and microscopic hematuria. Carbamazepine treatment was discontinued; antihistamines and steroids were started. Hyperglycemia, commencing on the first dose of the steroid given, persisted even after the discontinuation of steroids and improvement of other signs. There were no signs of pancreatitis or type 1 diabetes clinically in laboratory tests. Her blood glucose levels were regulated at first with insulin and later with metformin. Within 1 year of follow-up, still regulated with oral antidiabetics, she has been diagnosed with type 2 diabetes. Formerly, long-term sequelae related to “drug rash with eosinophilia and systemic symptoms syndrome” such as hepatic and renal failure, type 1 diabetes mellitus, Grave's disease, autoimmune hemolytic anemia, and lupus have also been reported. However, up to date, no cases with type 2 diabetes have been reported as long-term sequelae. To our knowledge, this is the first case in the literature presenting with type 2 diabetes as long-term sequelae. PMID:26862317

    Vitamin D deficiency is highly prevalent worldwide and has been linked to many diseases. The aims of the present study were to assess the vitamin D status of Jordanians at the national level and to identify groups of the population at high risk for vitamin D deficiency. Vitamin D status was assessed in a national sample of 5,640 subjects aged ≥7 years. The study involved interviews, laboratory measurements of 25(OH)D and others, and physical measurements. The present report deals, exclusively, with subjects aged >18 years. The prevalence of low vitamin D status [25(OH)D <30 ng/ml] was 37.3% in females compared to 5.1% in males. Dress style in females was independently related to low vitamin D status; women wearing 'Hijab' (adjusted OR = 1.7, p = 0.004) or 'Niqab' (adjusted OR = 1.5, p = 0.061) were at a higher risk for low vitamin D status than were western-dressed women. The high prevalence of low vitamin D status in females in contrast with a low prevalence in males, together with a higher prevalence in women wearing Hijab or Neqab, calls for action to increase the population's awareness and to develop strategies to reduce this risk among women, particularly those wearing dress styles that cover most or all of their skin.

    In this secondary analysis of videotape data, we describe birth talk demonstrated by caregivers to women during the second stage of labor. Birth talk is a distinctive verbal register or a set of linguistic features that are used with particular behaviors during specific situations, has a particular communication purpose, and is characterized by distinctive language features. Birth talk is found cross-culturally among speakers of diverse languages. Our findings show that birth talk occurred mainly during contractions and co-occurred with two general styles of caregiving: "directed toward forced bearing down" and "supportive of physiologic bearing down." We also describe talk that occurred during rest periods, which was similar across the two styles. Caregivers' use of language tended to be either procedural (giving directions, instructions) or comfort related (encouraging and supporting). Linguistic features of the talk consisted of utterances of short duration, level pitch patterns with no sudden pitch shifts, and a restricted pitch range.

    Binge Eating Disorder (BED) is currently recognized as a severe disorder associated with relevant psychiatric and physical comorbidity, and marked emotional distress. Shame is a specific negative emotion that has been highlighted as central in eating disorders. However, the effect of shame and underlying mechanisms on binge eating symptomatology severity remained unclear. This study examines the role of shame, depressive symptoms, weight and shape concerns and eating concerns, and body image-related cognitive fusion, on binge eating symptomatology severity. Participated in this study 73 patients with the diagnosis of BED, established through a clinical interview-Eating Disorder Examination 17.0D-who completed measures of external shame, body-image related cognitive fusion, depressive symptoms and binge eating symptomatology. Results revealed positive associations between binge eating severity and depressive symptoms, shame, weight and shape concerns, eating concerns and body image-related cognitive fusion. A path analysis showed that, when controlling for the effect of depressive symptoms, external shame has a direct effect on binge eating severity, and an indirect effect mediated by increased eating concern and higher levels of body image-related cognitive fusion. Results confirmed the plausibility of the model, which explained 43% of the severity of binge eating symptoms. The proposed model suggests that, in BED patients, perceiving that others see the self negatively may be associated with an entanglement with body image-related thoughts and concerns about eating, which may, in turn, fuel binge eating symptoms. Findings have important clinical implications supporting the relevance of addressing shame and associated processes in binge eating. Copyright © 2015 John Wiley & Sons, Ltd. Shame is a significant predictor of symptomatology severity of BED patients. Shame significantly impacts binge eating, even controlling for depressive symptoms. Shame significantly

    Food tastes better and people eat more of it when eaten with company than alone. Although several explanations have been proposed for this social facilitation of eating, they share the basic assumption that this phenomenon is achieved by the existence of co-eating others. Here, we demonstrate a similar "social" facilitation of eating in the absence of other individuals. Elderly participants tasted a piece of popcorn alone while in front of a mirror (which reflects the participant themselves eating popcorn) or in front of a wall-reflecting monitor, and were found to eat more popcorn and rate it better tasting in the self-reflecting condition than in the monitor condition. Similar results were found for younger adults. The results suggest that the social facilitation of eating does not necessarily require the presence of another individual. Furthermore, we observed a similar "social" facilitation of eating even when participants ate a piece of popcorn in front of a static picture of themselves eating, suggesting that static visual information of "someone" eating food is sufficient to produce the "social" facilitation of eating.

    Background Identifying childhood predictors of binge eating and understanding risk mechanisms could help improve prevention and detection efforts. The aim of this study was to examine whether features of attention deficit-hyperactivity disorder (ADHD), as well as childhood eating disturbances, predicted binge eating later in adolescence. Method We studied specific risk factors for the development of binge eating during mid-adolescence among 7,120 males and females from the Avon Longitudinal Study of Parents and Children (ALSPAC), a cohort study of children in the United Kingdom, using data from multiple informants to develop structural equation models. Repeated assessment of eating disturbances during childhood (mid-childhood overeating, late-childhood overeating, and early-adolescent strong desire for food), as well as teacher and parent reported hyperactivity/inattention during mid- and late-childhood, were considered as possible predictors of mid-adolescent binge eating. Results Prevalence of binge eating during mid-adolescence in our sample was 11.6%. The final model of predictors of binge eating during mid-adolescence included direct effects of late-childhood overeating (standardized estimate: 0.145, 95% CI: 0.038, 0.259; p=0.009) and early-adolescent strong desire for food (standardized estimate: 0.088, 95% CI: −0.002, 0.169; p=0.05). Hyperactivity/inattention during late-childhood indirectly predicted binge eating during mid-adolescence (standardized estimate: 0.085, 95% CI: 0.007, 0.128; p=0.03) via late-childhood overeating and early-adolescent strong desire for food. Conclusions Our findings indicate that early ADHD symptoms, in addition to an overeating phenotype, contribute to risk for adolescent binge eating. These findings lend support to the potential role of hyperactivity/inattention in the development of overeating and binge eating. PMID:26098685

    We demonstrated theoretically that the renormalization of the electron energy spectrum near the Dirac point of graphene by a strong high-frequency electromagnetic field (dressing field) drastically depends on polarization of the field. Namely, linear polarization results in an anisotropic gapless energy spectrum, whereas circular polarization leads to an isotropic gapped one. As a consequence, the stationary (dc) electronic transport in graphene strongly depends on parameters of the dressing field: A circularly polarized field monotonically decreases the isotropic conductivity of graphene, whereas a linearly polarized one results in both giant anisotropy of conductivity (which can reach thousands of percents) and the oscillating behavior of the conductivity as a function of the field intensity. Since the predicted phenomena can be observed in a graphene layer irradiated by a monochromatic electromagnetic wave, the elaborated theory opens a substantially new way to control electronic properties of graphene with light.

    This study evaluated the in vitro antibacterial activity and cytotoxicity of various commercially available silver-containing dressings (Ag dressing). Biohesive Ag (hydrocolloid, silver sulfadiazine), Aquacel® Ag (nonwoven fabric, ionic silver [Ag]), Algisite™ Ag (nonwoven fabric, Ag), Mepilex® Ag (foam, silver sulfate), and PolyMem® Ag (foam, nanocrystalline silver) were tested for characteristics of Ag release, antibacterial activity, and cytotoxicity. The release of Ag was investigated in cell culture medium at immersion periods of 6, 24, and 48 hours. The antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa were accessed by a disc diffusion test. The cytotoxicity was evaluated using V79 cells, by an extraction method. The cytotoxicity was not a monotonic function of the antibacterial activity among the Ag dressings and could not be simply explained by Ag-release properties. Biohesive Ag was regarded as a slow-release Ag dressing, showing the lowest cytotoxicity, while the antibacterial activity was classified as "strong" or "significant" against the two species of bacteria. Aquacel Ag and Algisite Ag showed higher antibacterial activity and cytotoxic effects, which were supported by the higher Ag release. Mepilex Ag showed the highest release of Ag, and the cytotoxicity was the highest among the Ag dressings. However, the antibacterial activity was classified as "significant" or "no activity" for P. aeruginosa and S. aureus, respectively. PolyMem Ag showed the lowest Ag release, and the antibacterial activity classified as "significant" or "no activity" for S. aureus and P. aeruginosa, respectively, whereas the cytotoxicity was similar to those of Aquacel Ag and Algisite Ag. The efficacy and adverse effects of the Ag dressings revealed differences that should be considered by clinicians during wound management.

    Hack the Planet (Wiley, 2010) explores how an idea once basically anathema to meetings like AGU has, in the space of a few years, become part of the geoscience mainstream. Through chapters involving researchers like David Battisti, Stephen Salter, Edward Teller and Brent Constanz the book documents the roots of this shift and how scientists are breaking new ground in the controversial field. And it shows how trying to engineer the planet's climate or manage its carbon poses novel scientific, geopolitical and moral risks and rewards. This session will cover how the topic of climate engineering has moved from something geoscientists don't talk about to something geoscientists can talk about, to something, in my view, that geoscientists must talk about.

    Prospective study on local treatment of pressure sores using calcium alginate and foam dressings in spina bifida patients. Investigate if this sequential approach is valid and safe for selected patients with neurological impairments. Using European Pressure Ulcer Grading System, after clinical evaluation of local sore, selected patients of Spina Bifida Center of Rome were treated with sequential calcium alginate and foam dressings for 12 weeks. Pressure ulcere surfaces were measured monthly by ulcer tracing. The endpoints were the mean absolute areas surface reduction during every month and number of patients achieving a 50% or more during study. 14 patients (7 males aged 12-24 years) with spina bifida and pressure sores were treated. Mean and standard deviation of mean surface area reduction were 12.5 ± 7.5 cm 2 at start of the study versus 3.7 ± 5.2 cm 2 after 12 weeks, p < 0.001. 75% of the patients reached mean surface area reduction of 50% during trial. Dressing tolerance was good in every patient. Calcium alginate and foam dressings are valid and safe approach in the treatment of pressure sores in selected patients with spina bifida. In fact, they protect the wound and create an environment favorable to healing.

    Cognitive behavioral guided self-help (CBTgsh) is an evidence-based, brief, and cost-effective treatment for eating disorders characterized by recurrent binge eating. However, more research is needed to improve patient outcomes and clarify treatment components most associated with symptom change. A main component of CBTgsh is establishing a regular pattern of eating to disrupt dietary restriction, which prior research has implicated in the maintenance of binge eating. The present study used session-by-session assessments of regular eating adherence and weekly binge totals to examine the association between binge frequency and regular eating in a sample of participants (n = 38) receiving 10 sessions of CBTgsh for recurrent binge eating. Analyses were conducted using Hierarchical Linear Modeling (HLM) to allow for data nesting, and a likelihood ratio test determined which out of three regression models best fit the data. Results demonstrated that higher regular eating adherence (3 meals and 2-3 planned snacks daily) was associated with lower weekly binge frequency in this sample, and both the magnitude and direction of the association were maintained after accounting for individual participant differences in binge and adherent day totals. Findings provide additional empirical support for the cognitive behavioral model informing CBTgsh. Possible clinical implications for treatment emphasis and sequencing in CBTgsh are discussed.

    The objective of this paper is to update knowledge of eating patterns of US adults with sex and ethnicity specific estimates and discuss the implications of reported patterns with respect to current resurgence of interest in the topic. The eating patterns data were from the NHANES 2009-2014 (n = 15,341 adults). Overall, American adults reported 4.96 ± 0.03 eating episodes in the recall. Women were more likely to report each of the three main meals and all three meals plus one or more snacks relative to men (P < 0.0001). Relative to other ethnic groups, non-Hispanic blacks were less likely to report each meal or a snack or all three meals, and the foods reported for meals and snacks were higher in energy density (P = 0.0001). Of the three meals, the dinner meal, and among snacks, the after-dinner snack, were reported by the highest percentage of Americans; these two eating episodes provided nearly 45% of the 24-h energy intake. The average dinnertime was 6:24 pm, and the average time of the last eating episode of the 24-h ingestive period was 8:18 pm. Given these findings, adoption of eating patterns that advocate less frequent eating and shift in the time of eating are likely to present a challenge. We know little about the validity of eating patterns determined from 24-h recalls or questionnaire instruments. The extent of within person variability and reporting errors in different eating pattern components also need further research. Copyright © 2018 Elsevier Inc. All rights reserved.

    Eating disorders during pregnancy, once thought to be rare, occur in a significant number of women. The incidences of the major eating disorders-anorexia nervosa and bulimia nervosa-are increasing because of cultural pressures on the drive for thinness. Because the age range for these major eating disorders overlaps with the age range for reproductive function, it is not unusual for a clinician to encounter a pregnant patient with a major eating disorder. Eating disorders attributable to the pregnant state include pregnancy sickness, pica, and ptyalism. The diagnostic criteria, etiology, nutritional behavioral influences, evolutionary psychological considerations where elucidated, and treatment of these disorders will be presented. Obstetricians and gynecologists, family physicians After completing this CME activity, physicians should be better able to review how the major eating disorders impact pregnancy, to diagnose eating disorders during pregnancy using the diagnostic criteria, and to treat eating disorders during pregnancy.

    A bilayer membrane (GKU) with a commercial polyurethane wound dressing as an outer layer and electrospun gelatin/keratin nanofibrous mat as an inner layer was fabricated as a novel wound dressing. Scanning electron micrographs showed that gelatin/keratin nanofibers had a uniform morphology and bead-free structure with average fiber diameter of 160.4nm. 3-(4,5-Dimethylthiazolyl)-2,5-diphenyltetrazolium bromide assay using L929 fibroblast cells indicated that the residues released from the gelatin/keratin composite nanofibrous mat accelerated cell proliferation. Cell attachment experiments revealed that adhered cells spread better and migrated deeper into the gelatin/keratin nanofibrous mat than that into the gelatin nanofibrous mat. In animal studies, compared with the bilayer membrane without keratin, gauze and commercial wound dressing, Comfeel®, GKU membrane gave much more number of blood vessels and a greater reduction in wound area at 4days, and better wound repair at 14days with a thicker epidermis and larger number of newly formed hair follicles. GKU membrane, thus, could be a good candidate for wound dressing applications. Copyright © 2017 Elsevier B.V. All rights reserved.

  14. Airborne bacterial dispersal during and after dressing and bed changes on burns patients.

    2015-02-01

    It is acknowledged that activities such as dressing changes and bed sheet changes are high-risk events; creating surges in levels of airborne bacteria. Burns patients are particularly high dispersers of pathogens; due to their large, often contaminated, wound areas. Prevention of nosocomial cross-contamination is therefore one of the major challenges faced by the burns team. In order to assess the contribution of airborne spread of bacteria, air samples were taken repeatedly throughout and following these events, to quantify levels of airborne bacteria. Air samples were taken at 3-min intervals before, during and after a dressing and bed change on a burns patient using a sieve impaction method. Following incubation, bacterial colonies were enumerated to calculate bacterial colony forming units per m(3) (cfu/m(3)) at each time point. Statistical analysis was performed, whereby the period before the high-risk event took place acted as a control period. The periods during and after the dressing and bed sheet changes were examined for significant differences in airborne bacterial levels relative to the control period. The study was carried out four times, on three patients with burns between 35% total burn surface area (TBSA) and 51% TBSA. There were significant increases in airborne bacteria levels, regardless of whether the dressing change or bed sheet change took place first. Of particular note, is the finding that significantly high levels (up to 2614cfu/m(3)) of airborne bacteria were shown to persist for up to approximately 1h after these activities ended. This is the most accurate picture to date of the rapidly changing levels of airborne bacteria within the room of a burns patient undergoing a dressing change and bed change. The novel demonstration of a significant increase in the airborne bacterial load during these events has implications for infection control on burns units. Furthermore, as these increased levels remained for approximately 1h afterwards

    Allergic contact dermatitis around chronic leg ulcers (CLU) is a common complication in patients presenting CLU and prolongs healing times. The aim of this study was to describe the rate of sensitization to modern dressings (MD) used in these patients and to assess whether there is a relation between the number of sensitizations and ulcer type, the time from onset of the ulcer, and patient age and gender. We conducted a retrospective study at Reims University Hospital between 2010 and 2014 that included all patients with CLU of vascular etiology surrounded by eczematous lesions, and who had one of the patch-tests in the following 3 series: European baseline±leg ulcers±corticosteroids. Among the 73 patients included, 43 % were polysensitized. Thirty-three patients (45 %) were sensitized to MD (38 % to hydrocolloids, 18 % to hydrogels, 7 % to hydrocellular dressings, 7 % to hydrofiber dressings, 5 % to contact layers and 3 % to alginates). Median age and sex did not differ between "polysensitized" patients and "non-polysensitized" patients (P=0.84 and P=0.25, respectively). Polysensitization was more frequent among patients presenting ulcers for more than 5 years (P=0.032). Practically half of all patients presenting CLU with surrounding contact dermatitis had sensitization to modern dressings (mostly hydrocolloids and hydrogels). The rate of sensitization increased with the length of presence of CLU. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Factor studied: duration of open abdomen, incidence of multi-organ failure, need for surgical revisions, length of stay (LOS) in ICU, nursing requirements (change of dressing/day), survival and integrity of abdominal wall after discharge. Treatment strategies included: open packing (OP), classic vacuum assisted (V.A.C.(R))-therapy with silicone net protection for the intestine (CV) and V.A.C.(R)-therapy with "abdominal dressing" a newly developed meshed polyvinyl wrap (AD). 21 patients were studied: 5 patients were treated with OP, 8 patients with CV and 8 patients with AD. Mean LOS was 65 (OP) vs. 53 (CV) vs. 42 (AD) days (NS), peritonitis related death was 3 (OP) vs. 1 (CV) vs. 0 (AD) (p < 0.05 Chisquare test). Median nursing effort was 4 dressings/day (OP), 0.5 (CV) and 0.5 (AD) (p < 0.005 OP vs CV, AD Kruskal-Wallis test). The "abdominal dressing"-therapy seems to be a more efficient treatment option in patients suffering from open abdomen following secondary peritonitis. A trend towards shorter ICU-LOS, lower mortality rates and reduced nursing requirements support our hypothesis.

    An antimicrobial dressing containing ionic silver was found effective in reducing surgical-site infection in a preliminary study of colorectal cancer elective surgery. We decided to test this finding in a randomized, double-blind trial. Adults undergoing elective colorectal cancer surgery at two university-affiliated hospitals were randomly assigned to have the surgical incision dressed with Aquacel Ag Hydrofiber dressing or a common dressing. To blind the patient and the nursing and medical staff to the nature of the dressing used, scrub nurses covered Aquacel Ag Hydrofiber with a common wound dressing in the experimental arm, whereas a double common dressing was applied to patients of control group. The primary end-point of the study was the occurrence of any surgical-site infection within 30 days of surgery. A total of 112 patients (58 in the experimental arm and 54 in the control group) qualified for primary end-point analysis. The characteristics of the patient population and their surgical procedures were similar. The overall rate of surgical-site infection was lower in the experimental group (11.1% center 1, 17.5% center 2; overall 15.5%) than in controls (14.3% center 1, 24.2% center 2, overall 20.4%), but the observed difference was not statistically significant (P = 0.451), even with respect to surgical-site infection grade 1 (superficial) versus grades 2 and 3, or grade 1 and 2 versus grade 3. This randomized trial did not confirm a statistically significant superiority of Aquacel Ag Hydrofiber dressing in reducing surgical-site infection after elective colorectal cancer surgery.

    As with most kinds of inner experience, it is difficult to assess actual self-talk frequency beyond self-reports, given the often hidden and subjective nature of the phenomenon. The Self-Talk Scale (STS; Brinthaupt et al., 2009) is a self-report measure of self-talk frequency that has been shown to possess acceptable reliability and validity. However, no research using the STS has examined the accuracy of respondents’ self-reports. In the present paper, we report a series of studies directly examining the measurement of self-talk frequency and functions using the STS. The studies examine ways to validate self-reported self-talk by (1) comparing STS responses from 6 weeks earlier to recent experiences that might precipitate self-talk, (2) using experience sampling methods to determine whether STS scores are related to recent reports of self-talk over a period of a week, and (3) comparing self-reported STS scores to those provided by a significant other who rated the target on the STS. Results showed that (1) overall self-talk scores, particularly self-critical and self-reinforcing self-talk, were significantly related to reports of context-specific self-talk; (2) high STS scorers reported talking to themselves significantly more often during recent events compared to low STS scorers, and, contrary to expectations, (3) friends reported less agreement than strangers in their self-other self-talk ratings. Implications of the results for the validity of the STS and for measuring self-talk are presented. PMID:25999887

  1. 150 patient experiences with a soft silicone foam dressing.

    PubMed

    Bateman, Sharon Dawn

    Pain, malodour and exudate from acute and chronic wounds can be catastrophic to the patient. Excessive exudate results in significant tissue damage to the wound bed and surrounding skin, reduces quality of life, and often requires costly specialist service input. Effective wound assessment and management including appropriate dressing choice is, therefore, paramount to ensure wound healing can take place in a timely manner. This observational evaluation explores 150 ward-based patients who presented with acute and chronic exuding wounds; it examines and evaluates the proposed benefits of the Cutimed(®) Siltec foam dressing range over a 4-month period in an acute hospital setting. The outcomes of the evaluation were exudate management, maceration reduction, atraumatic application and removal, non-adherence and patient experience. The evaluation highlights not only an overall positive improvement in exudate management and maceration reduction, non-adherence, atraumatic application and removal but also emphasises the importance of a positive patient experience in the wound-care journey.

  4. Acemannan-containing wound dressing gel reduces radiation-induced skin reactions in C3H mice

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Roberts, D.B.; Travis, E.L.

    To determine (a) whether a wound dressing gel that contains acemannan extracted from aloe leaves affects the severity of radiation-induced acute skin reactions in C3H mice; (b) if so, whether other commercially available gels such as a personal lubricating jelly and a healing ointment have similar effects; and (c) when the wound dressing gel should be applied for maximum effect. Male C3H mice received graded single doses of gamma radiation ranging from 30 to 47.5 Gy to the right leg. In most experiments, the gel was applied daily beginning immediately after irradiation. Dose-response curves were obtained by plotting the percentagemore » of mice that reached or exceeded a given peak skin reaction as a function of dose. Curves were fitted by logit analysis and ED{sub 50} values, and 95% confidence limits were obtained. The average peak skin reactions of the wound dressing gel-treated mice were lower than those of the untreated mice at all radiation doses tested. The ED{sub 50} values for skin reactions of 2.0-2.75 were approximately 7 Gy higher in the wound dressing gel-treated mice. The average peak skin reactions and the ED{sub 50} values for mice treated with personal lubricating jelly or healing ointment were similar to irradiated control values. Reduction in the percentage of mice with skin reactions of 2.5 or more was greatest in the groups that received wound dressing gel for at least 2 weeks beginning immediately after irradiation. There was no effect if gel was applied only before irradiation or beginning 1 week after irradiation. Wound dressing gel, but not personal lubricating jelly or healing ointment, reduces acute radiation-induced skin reactions in C3H mice if applied daily for at least 2 weeks beginning immediately after irradiation. 31 refs., 4 figs., 1 tab.« less

  5. Clinical safety and effectiveness evaluation of a new antimicrobial wound dressing designed to manage exudate, infection and biofilm.

    2017-02-01

    The objective of this work was to evaluate the safety and effectiveness of a next-generation antimicrobial wound dressing (NGAD; AQUACEL ® Ag+ Extra™ dressing) designed to manage exudate, infection and biofilm. Clinicians were requested to evaluate the NGAD within their standard protocol of care for up to 4 weeks, or as long as deemed clinically appropriate, in challenging wounds that were considered to be impeded by suspected biofilm or infection. Baseline information and post-evaluation dressing safety and effectiveness data were recorded using standardised evaluation forms. This data included wound exudate levels, wound bed appearance including suspected biofilm, wound progression, skin health and dressing usage. A total of 112 wounds from 111 patients were included in the evaluations, with a median duration of 12 months, and biofilm was suspected in over half of all wounds (54%). After the introduction of the NGAD, exudate levels had shifted from predominantly high or moderate to low or moderate levels, while biofilm suspicion fell from 54% to 27% of wounds. Wound bed coverage by tissue type was generally shifted from sloughy or suspected biofilm towards predominantly granulation tissue after the inclusion of the NGAD. Stagnant (65%) and deteriorating wounds (27%) were shifted to improved (65%) or healed wounds (13%), while skin health was also reported to have improved in 63% of wounds. High levels of clinician satisfaction with the dressing effectiveness and change frequency were accompanied by a low number of dressing-related adverse events (n = 3; 2·7%) and other negative observations or comments. This clinical user evaluation supports the growing body of evidence that the anti-biofilm technology in the NGAD results in a safe and effective dressing for the management of a variety of challenging wound types. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

  6. What Is the Correct Answer about The Dress' Colors? Investigating the Relation between Optimism, Previous Experience, and Answerability.

    The Dress photograph, first displayed on the internet in 2015, revealed stunning individual differences in color perception. The aim of this study was to investigate if lay-persons believed that the question about The Dress colors was answerable. Past research has found that optimism is related to judgments of how answerable knowledge questions with controversial answers are (Karlsson et al., 2016). Furthermore, familiarity with a question can create a feeling of knowing the answer (Reder and Ritter, 1992). Building on these findings, 186 participants saw the photo of The Dress and were asked about the correct answer to the question about The Dress' colors (" blue and black," "white and gold," "other, namely…," or "there is no correct answer" ). Choice of the alternative "there is no correct answer" was interpreted as believing the question was not answerable. This answer was chosen more often by optimists and by people who reported they had not seen The Dress before. We also found that among participants who had seen The Dress photo before, 19%, perceived The Dress as "white and gold" but believed that the correct answer was "blue and black ." This, in analogy to previous findings about non-believed memories (Scoboria and Pascal, 2016), shows that people sometimes do not believe the colors they have perceived are correct. Our results suggest that individual differences related to optimism and previous experience may contribute to if the judgment of the individual perception of a photograph is enough to serve as a decision basis for valid conclusions about colors. Further research about color judgments under ambiguous circumstances could benefit from separating individual perceptual experience from beliefs about the correct answer to the color question. Including the option "there is no correct answer " may also be beneficial.

    Second degree facial burns usually impart high wound site pain levels and patient discomfort due to the abundance of facial sensory innervation, as well as the development of edema and inflammation that accompany wound healing. Frequent changing of adherent dressings causes additional procedural pain and may prolong healing due to recurring damage to the wound bed. We applied face masks, made on-site from a drug free polymeric membrane dressing, to 8 patients with superficial and deep 2nd degree facial burns. Time to full re-epithlialization was recorded during treatment. Pain, overall comfort, and result satisfaction were evaluated using a questionnaire (10-point Likert scales. From 1=minimum to 10=maximum) on follow-up (mean follow up 14.4 months, range 9-18). These results were compared to a historical cohort of patients with facial burns that were treated with an antibiotic ointment. Results showed mean re-epithelialization time of 6.5 days (as compared to 8.5 days in the cohort group), low pain ratings (mean: 2.6; range: 4.7 in the control group), mixed comfort levels (mean: 4.7/10; 4 in the control group) and high result satisfaction (mean: 7.8; 6.2 in the control group). Nursing staff described pain-free dressing changes and positively noted non-adherence and high absorbance capacity of the polymer, necessitating less dressing changes. Inflammation was contained to the actual site of injury. No complications in terms of infection or allergic reaction were observed. Overall, the polymeric membrane facial dressing seems to be a promising means of reducing pain and ensuring uninterrupted wound healing in 2nd degree facial burns.

    Combining the advantages of the dressed states and superconducting quantum interference device (SQUID) qubits, we propose an efficient scheme to generate Greenberger-Horne-Zeilinger (GHZ) states for three SQUID qubits. Firstly, we elaborate how to generate GHZ states of three SQUID qubits by choosing a set of dressed states suitably. Then, we compare the scheme by using dressed states with that via the adiabatic passage. Lastly, the influence of various decoherence factors, such as cavity decay, spontaneous emission and dephasing, is analyzed numerically. All of the results show that the GHZ state can be obtained fast and with high fidelity and that the present scheme is robust against the cavity decay and spontaneous emission. In addition, our scheme is more stable against the dephasing than the adiabatic scheme.

    Honey has antibacterial and antimicrobial properties. This study was conducted to evaluate the efficacy and role of honey as local wound dressing agent in the management of diabetic foot and its effect on rate of amputation. This prospective observational study was done in the general surgery department, Al- Noor Specialist hospital, Holly Makkah, KSA from 1st March, 2007 to 31st May, 2008 (15 months). This study includes 172 patients of either gender, above 18 years of age, belonging to different nationalities admitted to A1- Noor specialist hospital, Holly Makkah, KSA. A total of 172 patients with male to female ratio 1.54:1 were admitted from 1st March, 2007 to 31st May, 2008 with complicated and non-healing diabetic foot ulcers. Out of these 172 patients, 135 (78.48%) were Saudi and 37 (21.52%) were non Saudi residents with ratio of 3.6:1. After admission and resuscitation, all the patients under went early surgical debridement and dressing with the thick layer of honey locally available. Wounds became healthy within 7-35 days. Three patients (1.75%) underwent big toe amputation and 2 (1.16%) patients under.went below knee amputations. Twenty (11.6%) patients under went split skin grafting to cover the wound while in other patients wound healed by secondary intention. Use of honey significantly reduced rate of amputation and improve wound healing when used for wound dressing in chronic diabetic foot ulcers.

    IN BRIEF The DASH (Dietary Approaches to Stop Hypertension) eating plan is an acceptable eating pattern for people who have diabetes. In addition to promoting blood pressure control, this eating pattern has been shown to improve insulin resistance, hyperlipidemia, and even overweight/obesity. This balanced approach promotes consumption of a variety of foods (whole grains, fat-free or low-fat dairy products, fruits, vegetables, poultry, fish, and nuts) and is appropriate for the entire family.

    Binge eating is prevalent among adolescents, but little is known about how parents and friends may influence such behaviors. This study examined associations between adolescent binge eating behaviors, and similar behaviors in their parents and friends. Participants were 2,770 target adolescent boys and girls who had at least one friend and/or parent who also participated. Logistic regression, stratified by gender, examined associations between parents' and friends' self-reported binge eating, and similar behaviors in target adolescents. Girls' binge eating was associated with their male friends' (odds ratio = 2.33; p = 0.03) and fathers' binge eating (odds ratio = 3.38; p = 0.02), but not with their female friends' or mothers' binge eating (p > 0.05). For boys, binge eating was not associated with parents' or friends' behavior. Adolescent girls' binge eating is associated with similar behaviors in their other-sex parents and friends. Results should be replicated, and mechanisms explaining this relation should be further explored. Copyright © 2013 Wiley Periodicals, Inc.

    Miller, Jessie L; Vaillancourt, Tracy; Hanna, Steven E

    2009-04-01

    To test a theoretically driven second-order factor model of eating disorders, with eating-disordered thoughts and eating-disordered behaviors representing the higher order factors, we conducted a confirmatory factor analysis using a female university student sample (N=1816). The 'Thought' latent construct was comprised of indicators representing fear of fat and dissatisfaction with body shape/weight and the latent construct 'Behavior' was comprised of indicators representing binging, purging and restricting. From the thought and behavior latent factors, composite groups were created by varying the level of thoughts and behaviors (high, moderate, and few/or none). We examined the independent contributions of thoughts and behaviors on a measure of psychopathology (depression). A second-order model of "eating disorder thoughts" and "eating disorder behaviors" was supported by the data, based on model fit, factor loadings, and model parsimony. Mean scores on depression were clinically significant for groups engaged in any level of eating disorder behavior whereas thoughts contributed to risk for depression only at the extreme end. Because of the disproportionate representation of eating disorder thoughts (high) and eating disorder behaviors (low) in non-clinical populations, the measurement and detection of eating disorders may be enhanced by measuring thoughts separate from behaviors.

    Objective To compare the characteristic meal patterns of adolescents with and without loss of control (LOC) eating episodes. Method The Eating Disorder Examination was administered to assess self-reported LOC and frequency of meals consumed in an aggregated sample of 574 youths (12-17 y; 66.6% female; 51.2% Caucasian; BMI-z: 1.38 ± 1.11), among whom 227 (39.6%) reported LOC eating. Results Compared to those without LOC, youth with LOC were less likely to consume lunch and evening meals (ps<.05), but more likely to consume morning, afternoon, and nocturnal snacks (ps≤.05), accounting for age, sex, race, socio-economic status, BMI-z, and treatment-seeking status. Discussion Adolescents with reported LOC eating appear to engage in different meal patterns compared to youth without LOC, and adults with binge eating. Further research is needed to determine if the meal patterns that characterize adolescents with LOC play a role in worsening disordered eating and/or excessive weight gain. PMID:23015352

    To examine 5-year longitudinal associations between family meal frequency and disordered eating behaviors in adolescents. Longitudinal study. Participants from 31 Minnesota schools completed in-class assessments in 1999 (time 1) and mailed surveys in 2004 (time 2). Adolescents (N=2516) who completed Project EAT (Eating Among Teens)-I (time 1) and -II (time 2) assessments. Time 1 family meal frequency and time 2 disordered eating behaviors, including extreme weight control behaviors (self-induced vomiting and use of laxatives, diet pills, or diuretics), less extreme unhealthy weight control behaviors (eating very little, fasting, using food substitutes, skipping meals, or smoking), binge eating, and chronic dieting. Among adolescent girls, time 1 regular family meals (> or = 5 meals/wk) were associated with lower prevalences of time 2 extreme weight control behaviors (odds ratio, 0.71; 95% confidence interval, 0.52-0.97), even after adjusting for sociodemographic characteristics, body mass index, family connectedness, parental encouragement to diet, and extreme weight control behaviors at time 1. Associations with other disordered eating behaviors were also suggestive of a protective effect of family meals in unadjusted analyses but were not statistically significant in adjusted analyses. Among adolescent boys, regular family meals did not predict lower levels of disordered eating behaviors. The high prevalence of disordered eating behaviors among adolescent girls and the protective role of family meals suggest a need for interventions aimed at promoting family meals. Further exploration of predictors of disordered eating behaviors in adolescent boys and the role of family meals is warranted.

     Objective. The aim of this study was to compare the health-related quality of life (HRQoL) and self-esteem of patients who underwent split-thickness skin grafting, when either cellulose dressings or rayon dressings were applied to the donor sites. A total of 25 patients, who were enrolled at five participant hospitals and required split-thickness skin grafting for various clinical reasons, were randomized into two treatment groups, the rayon dressing group (n = 13), or the cellulose dressing group (n = 12). All patients were assessed preoperatively and 60 days postoperatively. The HRQoL was assessed with the Short Form-36 (SF-36) health survey questionnaire, and self-esteem was evaluated using the Rosenberg Self-Esteem Scale (RSE)/UNIFESP-EPM (Brazilian versions). There were no surgery-related complications during the study period. In both treatment groups, SF-36 scores for emotional role, mental health, vitality, and general health decreased from baseline. RSE scores increased from baseline in both treatment groups, showing a reduction in self-esteem after treatment. There was a statistical difference (P = 0.024) in the SF-36 bodily pain domain for the rayon group. There were no significant differences in HRQoL and self-esteem between treatment groups. In the rayon-dressing group, there was a significant decrease in bodily pain from baseline .

    Plasticized polyvinylchloride film has been used in this burns unit for a long time for dressings before the ward round, before surgery, and when the burned patient is transferred from the casualty department to the burns unit. Plasticized polyvinylchloride film is easy to use, safe, and causes no pain. Most importantly, in the present financial climate, it is cheap. PMID:3103775

    Pressure ulcers (PrUs) are ischemic wounds in the skin and underlying tissues caused by long-standing pressure force over an external bone or cartilaginous surface. PrUs are an important challenge for the overall health system because can prolong patient hospitalization and reduce quality of life. Moreover, 95% of PrUs are avoidable, suggesting they are caused by poor quality care assistance. PrUs are also costly, increasing national costs. For example, they represent about 5% of overall annual health expenses in Spain. Stages I and II PrUs have a combined prevalence of 65%. According main clinical guidelines, stage II PrUs (PrU-IIs) are usually treated by applying special dressings (polyurethane or hydrocolloid). However, little scientific evidence regarding their efficacy has been identified in scientific literature. Our aim is to assess the comparative efficacy of adhesive polyurethane foam and hydrocolloid dressings in the treatment of PrU-IIs in terms of healed ulcer after 8 weeks of follow-up. This paper describes the development and evaluation protocol of a randomized clinical trial of two parallel treatment arms. A total of 820 patients with at least 1 PrU-II will be recruited from primary health care and home care centers. All patients will receive standardized healing procedures and preventive measures (e.g. positional changes and pressure-relieving support surfaces), following standardized procedures. The main outcome will be the percentage of wounds healed after 8 weeks. Secondary outcomes will include cost-effectiveness, as evaluated by cost per healed ulcer and cost per treated patient and safety evaluated by adverse events. This trial will address the hypothesis that hydrocolloid dressings will heal at least 10% more stage II PrUs and be more cost-effective than polyurethane foam dressings after 8 weeks. This trial has been registered with controlled-trials number ISCRCTN57842461 and EudraCT 2012-003945-14.

    This case study describes treatment for a 52-year-old man with a recurrent venous leg ulcer using a collagen dressing with extracellular matrix. The patient was admitted to the wound care service for a 3-week-old recurrent venous ulcer. Treatment included application of a collagen dressing with extracellular matrix twice weekly or as needed by the patient; application of a secondary dressing (4 × 4 gauze); and coverage with an expandable netting or gauze using a conforming stretch gauze bandage and latex-free dressing retention tape. The initial venous leg ulcer in this patient required 10 weeks to achieve closure. Ninety-eight percent resolution of the recurrent ulcer had occurred within 4 weeks of treatment, with complete closure at 7 weeks. The average healing time for recurrent venous ulcers is reported in the literature to be longer than initial venous ulcers. In the case provided, collagen ECM dressings promoted complete wound healing in 49 days.

    Chronic wounds require frequent dressing changes. Adhesive dressings used for this indication can be damaging to the stratum corneum, particularly in the elderly where the skin tends to be thinner. Understanding the level of damage caused by dressing removal can aid dressing selection. This study used a novel methodology that applied a stain to the skin and measured the intensity of that stain after repeated application and removal of a series of different adhesive types. Additionally, a traditional method of measuring skin barrier damage (transepidermal water loss) was also undertaken and compared with the staining methodology. The staining methodology and measurement of transepidermal water loss differentiated the adhesive dressings, showing that silicone adhesives caused least trauma to the skin. The staining methodology was shown to be as effective as transepidermal water loss in detecting damage to the stratum corneum and was shown to detect disruption of the barrier earlier than the traditional technique. © 2012 John Wiley & Sons A/S.

    Pain arising in burns sufferers is often severe and protracted. The prospect of a dressing change can heighten existing pain by impacting both physically and psychologically. In this trial we examined whether pre-procedural virtual reality guided relaxation added to patient controlled analgesia with morphine reduced pain severity during awake dressings changes in burns patients. We conducted a prospective randomized clinical trial in all patients with burns necessitating admission to a tertiary burns referral centre. Eligible patients requiring awake dressings changes were randomly allocated to single use virtual reality relaxation plus intravenous morphine patient controlled analgesia (PCA) infusion or to intravenous morphine patient controlled analgesia infusion alone. Patients rated their worst pain intensity during the dressing change using a visual analogue scale. The primary outcome measure was presence of 30% or greater difference in pain intensity ratings between the groups in estimation of worst pain during the dressing change. Of 88 eligible and consenting patients having awake dressings changes, 43 were assigned to virtual reality relaxation plus intravenous morphine PCA infusion and 43 to morphine PCA infusion alone. The group receiving virtual reality relaxation plus morphine PCA infusion reported significantly higher pain intensities during the dressing change (mean=7.3) compared with patients receiving morphine PCA alone (mean=5.3) (p=0.003) (95% CI 0.6-2.8). The addition of virtual reality guided relaxation to morphine PCA infusion in burns patients resulted in a significant increase in pain experienced during awake dressings changes. In the absence of a validated predictor for responsiveness to virtual reality relaxation such a therapy cannot be recommended for general use in burns patients having awake dressings changes.

    A series of novel polyurethane/siloxane-based wound dressing membranes was prepared through sol-gel reaction of methoxysilane end-functionalized urethane prepolymers composed of castor oil and ricinoleic methyl ester as well as methoxysilane functional aniline tetramer (AT) moieties. The samples were fully characterized and their physicochemical, mechanical, electrical, and biological properties were assayed. The biological activity of these dressings against fibroblast cells and couple of microbes was also studied. It was revealed that samples that displayed electroactivity by introduction of AT moieties showed a broad range of antimicrobial activity toward different microorganisms, promising antioxidant (radical scavenging) efficiency and significant activity for stimulation of fibroblast cell growth and proliferation. Meanwhile, these samples showed appropriate tensile strength and ability for maintaining a moist environment over a wound by controlled equilibrium water absorption and water vapor transmission rate. The selected electroactive dressing was subjected to an in vivo assay using a rat animal model and the wound healing process was monitored and compared with analogous dressing without AT moieties. The recorded results showed that the electroactive dressings induced an increase in the rate of wound contraction, promoted collagen deposition, and encouraged vascularization in the wounded area. On the basis of the results of in vitro and in vivo assays, the positive influence of designed dressings for accelerated healing of a wound model was confirmed.

    Research on emotional eating mostly focuses on negative emotions. Much less is known about how positive emotions relate to overeating and binge eating (BE). The aim of the current study was to construct a scale for positive and negative emotional eating and to assess its predictive validity. In study 1, the Positive-Negative Emotional Eating Scale (PNEES) was constructed and tested on 531 women, who also completed Eating Disorders Assessment Scale (EDAS). Results showed that a two-factor model constituting Positive emotional eating (PNEES-P) and Negative emotional eating (PNEES-N) fit the data well. PNEES-N also showed good convergent validity in assessing binge eating, correlating highly with EDAS subscale Binge eating. Further, a path analysis showed that after controlling for the mediating effect of PNEES-N, PNEES-P continued to significantly predict binge eating. In study 2 (N = 60), experience sampling method was used to assess overeating and BE in the natural environment. Palmtop computers were given to participants for a three-day study period that prompted them with questions regarding emotional experience, overeating, and BE. Results indicated that PNEES-P significantly predicted overeating, whereas PNEES-N predicted overeating and BE episodes only in a subsample of women who had experienced at least one overeating or BE episode. Thus, positive and negative emotional eating might have different relations with overeating and BE, with the latter being more characteristic of the severity/frequency of overeating and BE. New assessment tools that in addition to negative emotional eating also address positive emotional eating could be of potential help in planning intervention. Further, the tendency to overeat in response to positive emotions could be integrated into current models of eating disorders, especially when addressing relapse prevention.

    The aim of this study was to explore antecedents and sequelae of binge eating episodes. A sample of eating disorders (n = 154 women) was selected from a total of 1849 female respondents (out of 2500) recruited as part of a general population-based survey. Included participants met DSM-III-R criteria for anorexia nervosa (AN), bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) based on the Survey for Eating Disorders (SEDs). Preliminary criteria for binge eating disorder (BED) were added. Results indicated that the most frequently reported antecedents and consequences of binge eating were emotional and physiological factors. There were significant differences between the different ED subgroups in their frequency of binge eating episodes. Regarding antecedents of a binge eating episode, the SEDs-defined ED subgroups had overall differences in frequency on "stomach feeling". In particular, the BN-group reported "euphoria" more frequently than the BED and EDNOS-groups. Concerning consequences of a binge eating episode, there were overall differences between the ED subgroups on "fall asleep", and in addition a borderline significance was found for "disturbed by others" (p = 0.059). None of the eight women in the AN group reported "euphoria" as a factor that terminated a binge eating episode. The findings may have important implications with regard to prevention and treatment of ED.

    Contemporary Western society has encouraged an obesogenic culture of eating amongst youth. Multiple factors may influence an adolescent's susceptibility to this eating culture, and thus act as a barrier to healthy eating. Given the increasing prevalence of obesity amongst adolescents, the need to reduce these barriers has become a necessity.…

    Emotion suppression may lead to ironic increases in emotional experience. More important, suppression is a transactional process, creating stress and disrupting interactions for the suppressor and those in social interactions with individuals who are suppressing emotion. However, no research has examined the behavioral consequences of emotion suppression in close relationships. We examine the possibility that emotion suppression will predict eating behaviors as a secondary emotion regulatory strategy among 1,556 parent-adolescent dyads (N = 3,112), consistent with evidence suggesting that suppression influences eating at the individual-level. Actor-partner interdependence models and structural equation modeling demonstrate that one's own emotion suppression was associated with emotional eating; greater consumption of hedonic-low nutrient, high energy dense-foods; and lower consumption of fruits and vegetables (actor effects). One's partner's emotion suppression was also independently associated with one's own emotional eating; lower consumption of fruits and vegetables; and greater consumption of hedonic foods (partner effects), although this association was most consistent for adolescents' suppression and parents' eating (compared with the converse). These analyses suggest that dyadic emotion regulatory processes have implications on eating behavior. Moreover, analyses suggest that emotion suppression has potential implications on eating behaviors of others within close relationships with a suppressor, consistent with the notion that emotion regulation is a transactional process. These findings suggest that interventions to improve eating habits of parents and their adolescent children should consider dyadic emotion regulatory processes.

    The aim of this retrospective study was to evaluate the efficacy of vacuum-assisted closure (VAC) and GranuFoam Silver® dressing (KCI, San Antonio, TX) compared with conventional GranuFoam® dressing in the management of diabetic foot ulcers. Twenty-one consecutive patients treated with conventional or silver-coated foam dressing were reviewed retrospectively. The wound duration was 6 mo. Group 1 (n=10) received conventional foam dressing (GranuFoam) and group 2 (n=11) received silver-coated foam dressing (GranuFoam Silver). The wound surface area, duration of treatment, bacteriology, and recurrence were compared between the groups. The mean age of the patients was 61.70±10.52 y in group 1 and 67.27±11.28 y in group 2. In group 1, the average surface area of the wounds was 45.30±46.96 cm2 and 18.40±23.48 cm2 in the pre-treatment and post-treatment periods, respectively. There was a statistically significant difference between two measurements (p=0.005). Average duration of the treatment was 25.50±27.13 d in this group. In group 2, average surface area of the wounds in the pre-treatment and post-treatment periods were 41.55±36.03 cm2 and 7.64±3.91 cm2, respectively. There was a statistically significant difference between two measurements (p=0.003). Average duration of the treatment was 10.09±3.51 d in this group. The patients treated with silver-impregnated polyurethane foam dressing had reduced recurrence (2 vs. 7 wounds, p=0.030) and increased number of the culture-negative cases at the end of the treatment. With the results of the study, it was concluded that VAC GranuFoam silver dressing can be superior to conventional GranuFoam dressing in reducing the recurrence rate of infected diabetic foot ulcers.
