- CONCLUSIONS: There are no absolute contraindications to TRS therapy. The authors have formulated instructions for the prevention and treatment of the most common complications.The results demonstrate that TRS therapy is a simple, effective method for primary closure of difficult wounds, and large skin and soft-tissue defects. Larger randomized studies are required to further evaluate of the effectiveness, indications, complications and cost effectiveness of this innovative TRS therapy.

Tissue recovery is important in preventing tissue deterioration, which is induced by pressure and may lead to pressure ulcers (PU). Reactive hyperaemia (RH) is an indicator used to identify people at risk of PU. In this study, the effect of different recovery times on RH trend is investigated during repetitive loading. Twenty-one male Sprague-Dawley rats (seven per group), with body weight of 385-485 g, were categorised into three groups and subjected to different recovery times with three repetitive loading cycles. The first, second, and third groups were subjected to short (3 min), moderate (10 min), and prolonged (40 min) recovery, respectively, while fixed loading time and pressure (10 min and 50 mmHg, respectively). Peak hyperaemia was measured in the three cycles to determine trends associated with different recovery times. Three RH trends (increasing, decreasing, and inconsistent) were observed. As the recovery time is increased (3 min vs. 10 min vs. 40 min), the number of samples with increasing RH trend decreases (57% vs. 29% vs. 14%) and the number of samples with inconsistent RH trend increases (29% vs. 57% vs. 72%). All groups consists of one sample with decreasing RH trend (14%). Results confirm that different recovery times affect the RH trend during repetitive loading. The RH trend may be used to determine the sufficient recovery time of an individual to avoid PU development.
- Pressure ulcers in ICU patients: Incidence and clinical and epidemiological features: A multicenter study in southern Brazil. [Journal Article]
- ICIntensive Crit Care Nurs 2017 Apr 20
- CONCLUSIONS: PU incidence is related to severity of the patient's condition and predicted by Braden Scale score. The presence of PU is also related to adverse outcomes, such as MV duration and ICU and hospital mortality. It was also shown that patients with PU have a higher incidence of medical complications, such as acute renal failure, pneumonia, and the need for vasoactive drugs.

- CONCLUSIONS: Our results confirm that in patients with advanced-stage PU, the cultures of a superficial ulcer swab are not useful in either the diagnosis of a super-infection or the prediction of the role of involved microorganisms.

Patients with pressure ulcers are generally older, have a long hospital stay and often have a variety of comorbidities. The decision to perform surgery for pressure ulcer management can be difficult because of concerns about the risk of postoperative complications. The aim of this study was to analyse the relationship between comorbid conditions and surgical outcomes in order to guide patient selection for pressure ulcer surgery. In 57 patients, data on age, defect size, operating time, hospital stay, body mass index, surgical site, mobility state, cardiac ischaemic history, diabetes, renal failure, ventilator dependency, tracheostomy state, use of haemodilution therapy and cancer were evaluated using stepwise multiple logistic regression analysis to determine the relationships between variables. There were no postoperative cardiac ischaemic events. Wound complications occurred in 8 patients (14%), pneumonia in 12 patients (21·1%) and mortality in 1 patient (1·7%). The risk of postoperative pneumonia increased 1·069-fold in elderly patients (odds ratio = 1·069, P < 0·05) and increased 44·17-fold in preoperative ventilator users (odds ratio = 44·17, P < 0·05). The risk of wound complication increased 1·012-fold with the presence of a larger defect site (odds ratio = 1·012, P < 0·05) and increased 7·474-fold in patients who received haemodilution therapy (odds ratio = 7·474, P < 0·05). Our results indicate that most comorbid conditions did not significantly affect postoperative cardiopulmonary or wound complications. However, the risk of postoperative pneumonia increased in patients with ventilator use or old age, and the risk of wound complication increased in patients with a large defect size and in those who used haemodilution therapy.
- Lifestyle intervention for adults with spinal cord injury: Results of the USC-RLANRC Pressure Ulcer Prevention Study. [Journal Article]
- JSJ Spinal Cord Med 2017 Apr 17; :1-18
- CONCLUSIONS: Evidence for intervention efficacy was inconclusive. The intractable nature of MSPrI threat in high-risk SCI populations, and lack of statistical power, may have contributed to this inability to detect an effect.
- How common are foot problems among individuals with diabetes? Diabetic foot ulcers in the Dutch population. [Journal Article]
- DDiabetologia 2017 Apr 13
- CONCLUSIONS: The annual incidence rate of foot ulcers in the current study was lower than previously reported. This observation could reflect the efficacy of screening practices and an increased awareness among professionals and patients. Nevertheless, approximately one in every five diabetic individuals had at least one identifiable risk factor on foot examination. This signifies the importance of preventive screening.

Pressure ulcers belong to the most chalenging clinical problems. As hydration level of such wounds is important for optimal healing, preparation of new wound dressing (WD) materials for pressure ulcers requires thorough in vitro evaluation as prerequisite to final in vivo testing. The aims of the study were to: (a) develop a simple method of preparation of asymmetric polymeric membrane, (b) to propose a set of in vitro methods for membrane characterization during hydration. A polyvinyl alcohol asymmetric membrane with homogeneous skin layer and porous spongy layer was developed with nonadhesive properties and ability to absorb and retain the water. Complementary methods, including magnetic resonance imaging, allowed quantitative assessment of spatiotemporal aspects of membrane hydration, that is, global water uptake; swelling; local hydration in terms of proton density mapping; spatial distribution of T2 relaxation time; Young's modulus; piercing resistance. The proposed method of initial wound dressing evaluation seems to be promising to compare various WD formulations, to assess the time required to prepare WD membrane to be applied to the wound and to assess how long WD retains desired working properties. The developed asymmetric membrane seems to be a good candidate for further evaluation. It was found that: Young's modulus of hydrated membrane was comparable to those of human skin; asymmetrical structure was retained during the entire hydration period; each layer had its own distinct, hydration related, properties and their spatiotemporal evolution; relatively slow changes of membrane properties during the potential WD application time-span of several hours was observed. © 2017 Wiley Periodicals, Inc.
