Aim of the study

The main objective of this work is the development and psychometric validation of an instrument to evaluate nurses' adherence to the main recommendations issued for preventing pressure ulcers.

Material and methods

An instrument was designed based on the main recommendations for the prevention of pressure ulcers published in various clinical practice guides. Subsequently, it was proceeded to evaluate the face and content validity of the instrument by an expert group. It has been applied to 249 Spanish nurses took part in a cross-sectional study to obtain a psychometric evaluation (reliability and construct validity) of the instrument. The study data were compiled from June 2015 to July 2016.

Results

From the results of the psychometric analysis, a final 18-item, 4-factor questionnaire was derived, which explained 60.5% of the variance and presented the following optimal indices of fit (CMIN/DF: 1.40 p < 0.001; GFI: 0.93; NFI: 0.92; CFI: 0.98; TLI: 0.97; RMSEA: 0.04 (90% CI 0.025–0.054).

Conclusions

The results obtained show that the instrument presents suitable psychometric properties for evaluating nurses' adherence to recommendations for the prevention of pressure ulcers.  相似文献

Objectives

The aim of this study was to analyse the efficacy and safety of using platelet rich in growth factor (PRGF) as a local treatment for venous ulcers.

Methods

In a clinical trial 102 venous ulcers (58 patients) were randomly assigned to the study group (application of PRGF) or the control group (standard cure with saline). For both groups the healed area was calculated before and after the follow up period (twenty-four weeks). The Kundin method was used to calculate the healed area (Area = Length × Width × 0.785). Pain was measured at the start and end of treatment as a secondary variable for each group by record obtained by means of self-evaluation visual analogue scale.

Results

The average percentage healed area in the platelet rich plasma group was 67.7 ± 41.54 compared to 11.17 ± 24.4 in the control group (P = 0.001). Similarly, in the experimental group a significant reduction in pain occurred on the scale (P = 0.001). No adverse effects were observed in either of the two treatment groups.

Conclusions

The study results reveal that application of plasma rich in platelets is an effective and safe method to speed up healing and reduce pain in venous ulcers.  相似文献

Purpose

Custom contouring techniques are effective for reducing pressure ulcer risk in wheelchair seating. These techniques may assist the management of pressure ulcer risk during sleep for night time postural management.

Objectives

To investigate the effectiveness of custom contoured night time postural management components against planar support surfaces for pressure ulcer risk measures over the heels.

Method

Supine posture was captured from five healthy participants using vacuum consolidation and 3-dimensional laser scanning. Custom contoured abduction wedges were carved from polyurethane and chipped foams. Pressure mapping and the visual analog scale were used to evaluate the effectiveness of the contoured foams in reducing pressure and discomfort under the posterior heel against standard planar support surfaces.

Results

Custom contoured shapes significantly reduced interface pressures (p < 0.05) and discomfort scores (p < 0.05) when compared to planar support surfaces. Polyurethane foam was the most effective material but it did not differ significantly from chipped foam. Linear regression revealed a significant relationship between the Peak Pressure Index and discomfort scores (r = 0.997, p = 0.003).

Conclusions

The findings of this pilot study suggested that custom contoured shapes were more effective than planar surfaces at reducing pressure ulcer risk surrogate measures over the posterior heels with polyurethane foam being the most effective material investigated. It is recommended that Evazote foam should not be used as a support surface material for night time postural management.  相似文献

Background

Basal cell carcinoma (BCC) is the most frequent of all skin cancers in the white population. The typical dermoscopic features of pigmented BCCs have been well known. In the literature a new dermoscopic pattern of BCC has been reported as “blue-white variant”.

Objective

In this study, we aimed to evaluate the blue-white variant of BCC's seen in our cases at our Dermato-oncology Unit.

Methods

Patient files between the years 2003–2011 were searched for the cases with the histopathologic diagnosis of BCC. Among them, the cases that were compatible with the diagnosis of blue-white variant of BCC were determined. The morphological and clinical features of the lesions, dermoscopic images together with the histopathological slides were all evaluated.

Results

Among 350 histopathologically proven BCCs, 3.1% of them showed diffuse blue-white areas, namely “the blue-white variant”. On histopathological examination, typical aggregates of basaloid cells with nuclear atypia connected focally to the epidermis were observed. To our knowledge, this is the first research about the blue-white variant of pigmented BCC.

Conclusion

The blue-white variant of pigmented BCC seems to be the most challenging type of BCC in the diagnosis for the clinician.  相似文献

Background/Objective

Vitiligo is a common pigmentary disorder. Significant psychological effects and social discrimination was noticed among vitiligo patients. The severity of the negative impact is related to the society's attitude and knowledge. Therefore, this study aims to investigate knowledge and attitudes among general population towards vitiligo.

Methods

A cross-sectional study design was created using a survey based on the simulation video of the real situation. The participants were recruited from healthcare and non-healthcare workers attending Thammasat Hospital and Thammasat University. Demographic data, knowledge and attitudes towards the person in the video were recorded.

Results

Total 101 subjects completed the questionnaires. Less than one-fourth of the participants recognized this condition as vitiligo and realized that it was a hereditary disease. Around two-third known that it did not transmit via direct contact. In attitude perceptions, the lowest attitude score was in starting to date a vitiligo victim while the highest attitude score was found when individuals already married with vitiligo patients. Moreover, sufficient knowledge tended to have more positive attitudes towards the disease significantly (p < 0.004).

Conclusions

Misconceptions about vitiligo in this study seems to be higher than previous reports. This may be due to the visualized based questionnaires instead of asking from the word ‘vitiligo’ directly. Therefore, educational knowledge about disease recognition, causes and mode of transmission should be encouraged for public.  相似文献

Background

Negative pressure wound therapy (NPWT) is increasingly used prophylactically following surgery despite limited evidence of clinical or cost-effectiveness.

Objective

To evaluate whether NPWT is cost-effective compared to standard care, for the prevention of surgical site infection (SSI) in obese women undergoing elective caesarean section, and inform development of a larger trial.

Methods

An economic evaluation was conducted alongside a pilot randomised controlled trial at one Australian hospital, in which women were randomised to NPWT (n = 44) or standard care (n = 43). A public health care provider perspective and time horizon to four weeks post-discharge was adopted. Cost-effectiveness assessment was based on incremental cost per SSI prevented and per quality-adjusted life year (QALY) gained.

Results

Patients receiving NPWT each received health care costing AU$5887 (±1038) and reported 0.069 (±0.010) QALYs compared to AU$5754 (±1484) and 0.066 (±0.010) QALYs for patients receiving standard care. NPWT may be slightly more costly and more effective than standard care, with estimated incremental cost-effectiveness ratios (ICERs) of AU$1347 (95%CI dominant- $41,873) per SSI prevented and AU$42,340 (95%CI dominant- $884,019) per QALY gained. However, there was considerable uncertainty around these estimates.

Conclusions

NPWT may be cost-effective in the prophylactic treatment of surgical wounds following elective caesarean section in obese women. Larger trials could clarify the cost-effectiveness of NPWT as a prophylactic treatment for SSI. Sensitive capture of QALYs and cost offsets will be important given the high level of uncertainty around the point estimate cost-effectiveness ratio which was close to conventional thresholds.

Background

Pressure Ulcers (PUs) are a severe form of skin and soft tissue lesions, caused by sustained deformation. PU development is complex and depends on different factors. Skin structure and function change during prolonged loading on PU predilection sites and surfaces being in direct contact with skin are likely to have an impact as well. Little is known about the influence of fabrics on skin function under pressure conditions.

Objectives

To investigate skin responses to sustained loading in a sitting position and possible differences between two fabrics.

Methods

Under controlled conditions 6 healthy females (median age 65.0 (61.0–67.8) years) followed a standardized immobilization protocol of a sitting position for 45 min on a spacer and on a cotton fabric. Before and after the loading period skin surface temperature, stratum corneum hydration, transepidermal water loss (TEWL), erythema, skin elasticity and ’relative elastic recovery‘ were measured at the gluteal areas.

Results

A 45 min sitting period caused increases of skin surface temperature and erythema independent of the fabric. Loading on spacer fabric showed a two times higher increase of TEWL compared to cotton. Stratum corneum hydration showed slight changes after loading, skin elasticity and ’relative elastic recovery’ remained stable.

Conclusions

Sitting on a hard surface causes skin barrier changes at the gluteal skin in terms of stratum corneum hydration and TEWL. These changes are influenced by the fabric which is in direct contact to the skin. There seems to be a dynamic interaction between skin and fabric properties especially in terms of temperature and humidity accumulation and transport.  相似文献

Background

Caveolin-1 (CAV-1) is a key structural and functional membrane protein that is thought to play a role in controlling cellular proliferation and differentiation.

Objective

To study the immunohistochemical expression of caveolin-1 in psoriasis and the two common types of non-melanoma skin cancers (NMSCs); basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in comparison to normal control skin and to correlate their expression with disease severity and progression.

Patients and methods

This study included 90 patients and paraffin blocks (30 psoriasis, 30 BCC and 30 SCC) and 30 normal control skin specimens. Skin biopsy specimens were taken from all and examined for immunohistochemical expression of caveolin-1.

Results

Significant reduction of caveolin-1 expression was detected in all studied patients groups in comparison to control group. Caveolin-1 expression in psoriasis showed significant downregulation with progression of Psoriasis Area and Severity Index (PASI) score. In addition, caveolin-1 expression was significantly decreased in aggressive types of BCC compared to non-aggressive types. Furthermore, poorly differentiated SCC showed significantly reduced caveolin-1 expression compared to moderately and well differentiated SCC.

Conclusion

Caveolin-1 downregulation may increase the susceptibility to both benign and malignant hyperproliferative skin disorders. It could be useful as predictive biomarker of disease severity and progression.  相似文献

Aim of the study

To examine biophysical skin properties in the sacral region in spinal cord injury (SCI) patients suffering from a grade 1 pressure ulcer (PU) defined as non-blanchable erythema (SCI/PU), SCI patients in the post-acute phase (SCI/PA) and able-bodied participants (CON). Also, for SCI/PU patients, both the affected skin and healthy skin close to the PU were examined.

Study design

An experimental controlled study with a convenience sample.

Setting

A Swiss acute care and rehabilitation clinic specializing in SCIs.

Materials and methods

We determined hydration, redness, elasticity and perfusion of the unloaded skin in the sacral region of 6 SCI/PU patients (affected and healthy skin), 20 SCI/PA patients and 10 able-bodied controls. These measures were made by two trained examiners after the patients were lying in the supine position.

Results

The affected skin of SCI/PU patients showed elevated redness: median 595.5 arbitrary units (AU) (quartiles 440.4; 631.6) and perfusion: 263.0 AU (104.1; 659.4), both significantly increased compared to the healthy skin in SCI/PA patients and CON (p < 0.001). Similarly, healthy skin of SCI/PA patients showed elevated redness (p = 0.016) and perfusion (p < 0.001) compared to CON. On the other hand, differences in redness and perfusion between the affected and unaffected skin in SCI/PU patients were not significant. The results for skin hydration and skin elasticity were similar in all groups.

Conclusions

Skin perfusion and redness were significantly increased in grade 1 PUs and for healthy skin in both SCI/PA patients and CON participants; thus, these are important in understanding the pathophysiology of PUs and skin in SCI.  相似文献

Background/Objective

Dermatologists use the word lilac to describe a shade of erythema; especially in lichen planus, morphea, and dermatomyositis. The aim of this study to determine whether or not there is a color really consistent with a lilac color, when they perceive it.

Methods

Four illustrations were prepared for each of these three diseases. Only one illustration of each of the diseases had a color really consistent with a lilac color. Seventy-two physicians working in dermatology (16 residents, 20 teaching staffs, and 36 non-academician specialists) were included in this study. They were asked to choose the most representative illustration for each of the diseases.

Results

Only a few physicians chose illustrations having a color really consistent with a lilac color. In most commonly chosen illustrations, there was a rose or even a salmon color in the area perceived as having a lilac color by the physicians.

Conclusion

Our results might be explained by the color contrast phenomenon. In other words, a human may discern a verging towards lilac from an object not colored such by comparing its color to that of its background, so he may perceive this color.  相似文献

Background

Antimicrobial photodynamic therapy (APDT) has become a potential regimen to treat multidrug-resistant bacterial infections. Limited data showed indocyanine green (ICG), a safe and inexpensive contrast medium for eye angiography and hepatic function examination, is an effective photosensitizer in APDT to kill methicillin-resistant Staphylococcus aureus (MRSA) after excitation with laser.

Objective

We investigated the potentials of ICG-APDT with an inexpensive, non-coherent commercial near infrared (NIR) lamp against MRSA.

Methods

The inhibition of MRSA was studied after exposing bacteria to NIR with different light doses and concentrations of ICG. The selectivity on MRSA was examined on human fibroblasts. Bacterial virulence including the activities of coagulase and enterotoxin was investigated. The effects of singlet oxygen scavengers (tryptophan and ascorbic acid) and H2O2 on cell survival were evaluated. The morphology of bacteria after PDT was observed by transmission electron microscopy.

Results

ICG-PDT inhibited the growth of bacteria by 5 log (99.999% inhibition) with 200 J/cm2 at 65.5 mW/cm2 in the presence of 100 μg/mL ICG. Adding 0.1% H2O2 at a lower PDT dose (25 μg/mL ICG and 100 J/cm2) increased its efficacy by 5 log. This PDT dose was not toxic to human fibroblasts. PDT significantly reduced the level of bacterial virulence factors. The inhibition effects were decreased by tryptophan and ascorbic acid suggested singlet oxygen involved in the process. TEM showed severe non-selective cell destruction immediately after irradiation.

Conclusion

The study reveals ICG-PDT has the potential to treat MRSA by using a clinical accessible NIR lamp and photosensitizer.  相似文献

Background

The variation in the management of venous leg ulceration in the UK is partly attributable to an uncertain clinical environment but the quality of judgements is influenced by the how well nurses' confidence and accuracy are aligned.

Objectives

To assess UK community nurses' confidence in the accuracy of their diagnostic judgements and treatment choices when managing venous leg ulceration.

Design

Judgement Analysis.

Setting

UK community and primary care nursing services.

Participants

18 community non-specialist nurses working in district (home) nursing teams and general practitioner services and 18 community tissue viability specialist nurses.

Methods

Using judgement analysis methods, 18 community non-specialist nurses and 18 community tissue viability specialist nurses made diagnoses and treatment judgements about compression therapy for 110 clinical scenarios and indicated their confidence for each judgement. An expert panel made consensus judgements for the same scenarios and these judgements were used as a standard against which to compare the participants. Confidence analysis was used to assess the nurses' confidence about their diagnostic judgements and treatment choices.

Results

Despite being very experienced, both non-specialist nurses' and specialist tissue viability nurses' levels of confidence were not well calibrated with their levels of accuracy.

Conclusion

The results of this study are important as errors resulting from both over and under-confidence at the diagnostic phase of management may influence treatment choices, and thus increase the chances of treatment error.  相似文献

Introduction

Little is known about health activation and self-management behavior in preventing pressure ulcers (PU) in paraplegic patients. Therefore this study aimed to describe the extent of health activation and self-management behavior in paraplegics to prevent PU's and associations between this behavior and patient characteristics.Furthermore, we aimed to find differences in health activation in paraplegics who never had a PU compared to paraplegics with a previous history of PU's or a new-onset PU's.

Methods

A cross-sectional survey on health activation and self-management behavior was conducted among adult paraplegics recruited from two rehabilitation centers in the Netherlands. The Patient Activation Measure (PAM-score) was used to measure the extent of health activation. Patient statements on their level of self management behavior to prevent PU were evaluated.

Results

The mean PAM-score (0–100) was 54 (±8.1; n = 162) indicating a low level of health activation. Two indicators turned out to be statistically significant associated with health activation: level of education (OR = 2.2, p = 0.017) and degree of paraplegia (OR = 2.8, p = 0.036). Evaluation of health activation levels amongst paraplegics with or without a PU- history showed no significant difference. Analysis of patients statements demonstrated a large discrepancy between intended and actual behavior to prevent pressure ulcers.

Conclusion

Level of education and level of paraplegia are significantly associated with health activation. A positive PU-history is not associated with future responsible behavior nor for compliant behavior in terms of health management.  相似文献

Background

Kaposi's sarcoma (KS) is a reactive, multifocal, multicentric, angiogenic neoplastic proliferation that is thought to originate from endothelial cells that are infected with human herpesvirus-8 (HHV-8). This report examines a cohort of patients with classic Kaposi's sarcoma (KS) evaluated at the national institute of oncology over the 13-year period.

Methods

A retrospective analysis of 156 patients with classic KS, between January 2000 and November 2013, was performed. This study focused on the clinical presentation, staging, diagnosis, and treatment of classic KS.

Results

One hundred fifty-six patients (median age 69 and 115 male) were enrolled into the study. Median age at diagnosis was 69 (range: 32–95 years). Male/female ratio was 2.80. The most common location was the lower limbs. There were 75 stage I patients (48.1%), 8 stage II patients (22.4%), 31 stage III patients (19.9%) and 15 stage IV patients (9.6%). Surgery was the most common local treatment method (43%). 44 patients (28.2%) received radiotherapy (RT) at diagnosis. Cytotoxic treatment with chemotherapy or interferon-α was administered in 57 patients. Visceral involvement was observed in 10 patients (lung: nine patients, liver: one patient) and bone metastasis occurred in two patients at relapse.

Conclusion

This study is one of the largest reported series. Further studies are required and it will be important to standardize the assessment of disease activity and clinical response.  相似文献

Background

At present there is no established national minimum data set (MDS) for generic wound assessment in England, which has led to a lack of standardisation and variable assessment criteria being used across the country. This hampers the quality and monitoring of wound healing progress and treatment.

Aim

To establish a generic wound assessment MDS to underpin clinical practice.

Method

The project comprised 1) a literature review to provide an overview of wound assessment best practice and identify potential assessment criteria for inclusion in the MDS and 2) a structured consensus study using an adapted Research and Development/University of California at Los Angeles Appropriateness method. This incorporated experts in the wound care field considering the evidence of a literature review and their experience to agree the assessment criteria to be included in the MDS.

Results

The literature review identified 24 papers that contained criteria which might be considered as part of generic wound assessment. From these papers 68 potential assessment items were identified and the expert group agreed that 37 (relating to general health information, baseline wound information, wound assessment parameters, wound symptoms and specialists) should be included in the MDS.

Discussion

Using a structured approach we have developed a generic wound assessment MDS to underpin wound assessment documentation and practice. It is anticipated that the MDS will facilitate a more consistent approach to generic wound assessment practice and support providers and commissioners of care to develop and re-focus services that promote improvements in wound care.  相似文献

Background

Perforator flap techniques with conventional wound dressing have being extensively used in the management of soft-tissue defects. However; the flap's survival rate is not always guaranteed and the wound healing time always long. The aim of this study was to investigate the clinical effectiveness use of a freshly transplanted perforator flap in conjunction with Vacuum-assisted closure (VAC) for better clinical outcomes.

Methods

A prospective, randomized, effectiveness study comparing the clinical outcomes of VAC versus traditional wrap and bandages for the treatment of open wounds that required hospital admission and operative debridement using perforator flaps, was carried out from March 1, 2014 to March 31, 2016 at Wuhan University Zhongnan Hospital. Fifty-one eligible patients were randomized into two groups; study group (perforator flaps covered by VAC) and control group (perforator flaps covered by traditional wrap and bandages). The measured clinical endpoints included the time of the first post-operative dressing change, pain visual analogical scale, perforator flap infection rate, 95% perforator flap healing time and percentage of survived perforator flap.

Results

There was no statistically significant difference in the demographic profiles in the two cohorts. There were statistically significant differences in the clinical endpoints in the two groups (p < 0.001; p < 0.05, Table 2).

Conclusions

In summary, VAC combining with perforator flap technique, can diminish accumulated exudation of the transferring flap, protect against postoperative infection, prolong the interval between perforator flap relocation and first postoperative dressing change, decrease pain during removal of dressing, increase perforator flap survival rate, and shorten wound healing time, with a good aesthetic outcome, a good mobility and a satisfactory therapeutic result.  相似文献
