Modern dressing based on polymer microfibers with aluminum oxyhydroxide: properties and mechanism of wound healing

Objective: to investigate the structure of the new VitaVallis dressing and determine the mechanism of its wound healing effect. Materials and methods. To study the structure of the VitaVallis dressing, transmission and scanning electron microscopy methods were used. The course of the wound process was studied in 60 male mice of the Balb / c line. The healing of a wound defect under the influence of dressings was studied on the model of a “skin flap”. Morphometric evaluation of histological preparations was carried out by computer-aided graphical analysis of samples. Statistical processing of the results was carried out using the parametric (Student's test) and non-parametric (Wilcoxon's test) methods. For analysis, the program Statistica 6.0 was used. Results. The structure of the VitaVallis dressing is randomly spaced polymer fibers with a diameter of 1.0—5.0 microns, on the surface of which nanosheet structures of aluminum oxyhydroxide (AlOOH) are immobilized. In vivo experiments have shown that the use of VitaVallis dressing in the treatment of model wounds in mice promotes accelerated healing and leads to better epidermis organotypic differentiation and accelerates the maturation of granulation tissue. This effect is due to a combination of factors such as: reduction of inflammatory processes due to the removal and retention of wound exudate, including pathogenic microflora, stimulation of marginal epithelization, protection of the formed granulation tissue from drying out and acceleration of its maturation. Conclusion. Analysis of the structure and mechanism of the wound-healing action of the dressing VitaVallis suggests the effectiveness of its use in the local treatment of wounds.

724 Factors Influencing Healing Time After Enzymatic Debridement

Abstract Introduction Enzymatic debridement (ED) as a noninvasive method is widely used and has been researched in several studies. The influence of key components of the trauma and overall treatment on healing time are often underrepresented. This paper describes the results from 56 wounds treated in a burn unit to evaluate factors influencing the healing time. Methods From all patients admitted to our unit from the year 2014 to 2016, 56 were treated with ED. Preclinical data and clinical data were compared in a retrospective review. Patients were divided into two groups with a separator of healing time of 30 days. Results ED was provided in 56 wounds in 52 patients on average to 7.0% ± 6.0 %, median 4.8% of patient’s body surface area. Comparing the group with a healing time of more than 30 days and less than 30 days. Statistically significant differences with a p< 0.05 were found in the rate of preclinical intubations, inhalation injuries, the application of fluids before admission, the type of dressing used and the BAUX index. Highly significant differences with a p< 0.01 were found in the ratio of pseudoeschars which had to be operated on and in the modified BAUX index (MBI). Mostly used dressings were a polylactic membrane (PLM) and silicone dressings. In the silicone group, MBI was significantly higher than in the polylactic group and healing time was significantly faster in the PLM group. Comparing groups with a higher than average MBI of 67.5 the PLM and the silicone group had a comparable MBI (p=0.337), but the PLM group had a five days shorter healing time of 43 days (p=0.2768). In a logistic regression formula over all PLM and Silicone patients (Days for healing after ED = 1.53 + 8.9 * dressing (PLM=1, silicone=2) + 0.35*MBI - 5.15483*incomplete debridement (Yes=1, No=0) + 7.96*pseudoeschar to be operated on (Yes=1, No=0) the influence of dressings could be demonstrated. No statistical differences (p >0.05) could be found in age, etiology of burn (fire scald, electric current injury or electrical arch with a p=0.4), location of accident out- or inside a building, cold water therapy applied or not, in TBSA, percentage of partial deep burns and full-thickness burns or the percentage of patients taken to ICU as inpatients and the timing of ED as well as the completeness of ED and in ABSI. Conclusions Healing time was dependent on parameters such as preclinical intubations, inhalation injuries, dressings used, and the severity calculated by MBI. Dressings are one of the few settings which can be changed proactively to achieve better outcomes. PLM over all clinical conditions have a shorter healing time (31 days) compared to silicon dressings (49 days) Applicability of Research to Practice Immediate.

THE EFFECTS OF DRESS SHOES ON STABILITY DURING QUIET STANDING AND ENERGY CONSUMPTION WHILE WALKING

Footwear is an extremely important clothing item worn by all individuals. Currently, there is insufficient research regarding the influence of dress shoes on standing stability and energy consumption while walking. Therefore, the aim of this study was to evaluate the influence of dress shoes on the performance of normal subjects based on stability and energy consumption analysis. Fifteen normal subjects were recruited in this research study to stand and walk with and without shoes. The stability of the subjects in quiet standing was measured by the use of a force plate based on center of pressure (COP) sway. The energy consumption was evaluated by a heart rate monitoring system (Polar Electro) based on the physiological cost index (PCI). The mean values of PCI while walking with and without shoes were 0.29 ± 0.117 and 0.265 ± 0.112 beats/m, respectively (p-value > 0.05). The amplitudes of COP sways in the mediolateral and anteroposterior directions were 10.4 ± 3.5 and 25 ± 6.92 mm while standing with shoes and 9.3 ± 2.84 and 22.5 ± 5.25 mm in barefoot standing, respectively (p-value > 0.05). It can be concluded that wearing dress shoes does not influence the performance of subjects while standing or walking.

A Methodology for the Simulation of Surface-Contact Grinding Tool Topography

A new method of the abrasive tool topography simulation for surface-contact grinding is advanced based on the description of exposed grain feature and the stochastic allocation characteristic of abrasive grains emerges in grinding process. In this paper, particularities of surface-contact grinding and simulation method suitable for the particularities are discussed. The physical behaviors of abrasive tool topography are analyzed with respect to the effect of grain status, grain location and influence of dressing. The simulation model is proposed as synthesis of simulation for the grain size, grain location and influence of dressing. It has been shown from the simulation experiment that this feature description and probability statistics theory based topography model can describe the particularities very well and is proved feasible for simulation of surface-contact grinding.

The Effects of Concert Dress and Physical Appearance on Perceptions of Female Solo Performers

This study investigates the importance of visual information in performance, focusing on the influence of dress on the musical evaluation of female classical soloists. In this study, four female violinists were filmed playing in four states of dress: jeans, a nightclubbing dress, black concert dress and point-light condition (body movement is apparent but not physical appearance). Each clip was recorded in two conditions: both as the performer's own version and with a mastertrack dubbed over the top. The dubbed versions therefore had a constant musical soundtrack. Fifteen male and 15 female musicians (age range 17–66 years) were asked to rate clips on six point scales in terms of technical proficiency, musicality, appropriateness of dress and attractiveness of performer. Significant effects were found of condition, dress and performer, and an interaction of performer and dress was observed on participant perceptions. Implications of these perceptions of female performers suggest that observers have a strong concept of what constitutes appropriate dress for a female recitalist, as the concert dress was overwhelmingly favoured above the nightclubbing dress and jeans. There is evidence that the historical dominance of mental attributes over physical attributes continues, as performer 3 is rated high for technical proficiency and musicality, but lower for appropriateness of dress.

The influence of dressings and ointments on the qualitative and quantitative evaluation of burn wounds by ICG video-angiography: an experimental setup

Burn wound depth is difficult to determine. Even for experienced investigators the exact differentiation between superficial and deep dermal burns is not always possible. Therefore, methods for objective and reproducible measurements estimating the depth of burn wounds are of great clinical interest. One technique that appears to be able to differentiate between superficial and deep dermal burn wounds is ICG video-angiography. Since burn wounds are often covered with dressings and ointments or soiled with blood, it is necessary to evaluate the influence of these substances on ICG video-angiography and its performance as a measurement method. The most commonly used ointments and dressings were tested. All studied substances had a massive influence on ICG video-angiography and its measurements. They caused decreases by absorption of up to 63±36% and thereby falsely reported deeper burn wounds. The results of this study, suggest that in clinical practice, all dressings, ointments and blood should be completely removed at least 10 min prior to measurement by ICG video-angiography to gain exact and reproducible results.

The influence of dressings on venous ulcer healing — A randomised trial

To assess the effect of different dressings on venous ulcer healing. A randomised clinical trial. Patients were randomised to treatment with one of three dressings: a zinc oxide impregnated bandage, a zinc oxide impregnated stockingette, or an alginate dressing. All patients were treated as outpatients and had compression bandaging with two minimal stretch bandages (Elastocrepe) and a stockingette (Tubigrip) to keep the bandages in place. One hundred and thirteen patients (133 ulcerated limbs) with chronic ulceration of the leg due to venous disease alone, and attending Fremantle Hospital Leg Ulcer Clinic, Western Australia were entered into the study. Healing was measured as complete healing of the ulcerated limb or failure of the limb to heal within 9 months. There was no significant difference between the three groups in ulcer size, duration, and other parameters compared. Healing was affected significantly by ulcer size and which leg was ulcerated. There was significantly faster healing with the paste bandage. The use of a paste bandage significantly improved the healing of chronic venous ulcers when used in combination with compression bandaging, and compared to an alginate dressing and a zinc oxide impregnated stockingette.

Influence of Dress on Perception of Intelligence and Scholastic Achievement in Urban Schools with Minority Populations

Photographs of five clothing styles were manipulated in this investigation of perceived behavior, academic potential and intelligence of high school students. Teacher and student subjects from three urban secondary schools with 97%, 56% and 30% minority enrollments participated in the study. A repeated measures analysis of variance as well as a post hoc test were used for data analyses. Independent variables were clothing styles, sex of the model, school and race. Dependent variables were perception of intelligence, scholastic ability and school related behavior. Student and teacher subjects perceived differences in behavior, academic potential and intelligence of the models based on clothing worn. Differences for behavior and academic potential were significant for clothing style and sex of the model. There were significant interactions for academic potential by sex of the model and style, for school and style, as well as for style, school and race.

Influence of Dress on Perception of Intelligence and Expectations of Scholastic Achievement

Stimulus photographs of four clothing styles worn by a male and a female model were used to investigate the role clothing plays in perception of intelligence and academic expectations of high school students. Subjects were 750 high school students and 159 teachers from six schools in Ohio. One large suburban school, two urban schools, and three rural schools were represented. Repeated measures ANO VA was used to determine F value, and post hoc tests were conducted. Results indicate perception of intelligence and academic achievement are influenced by dress. Significant differences were found in perception of intelligence and scholastic ability for both student and teacher subjects based on clothing styles and sex of the model. There were significant differences among the schools for students but not for teachers. The influence of dress and gender on teachers'perception of the intellectual capabilities of students has serious implications for the classroom.

The Influence of Dress on Students' Perceptions of Teacher Characteristics

The purpose of this study was to examine the influence of a female teacher's clothing style on student perceptions of teacher characteristics, including approachability, knowledge, respect, and overall acceptability. High school students were provided with photographs of a teacher model dressed in four clothing styles and were asked to select one of the photos for each of 20 statements designed to reflect teacher characteristics. Chi square results revealed differences between the clothing styles on 19 of the 20 statements.
