Switching from Galenic to Advanced Dressings or Vacuum Assisted Closure Therapy Can Improve Quality of Life of Patients with Chronic Non-Responsive Pressure Skin Ulcers: Preliminary Data with Italian Translation of WOUND-Q.

Objective: A few studies have focused on the quality of life (QoL) of patients with chronic non-responsive pressure skin ulcers. The aim of this study was to assess how correct treatment (advanced wound care [AWC] dressings alone or vacuum assisted closure [VAC] therapy alone) changes the QoL of these patients. Approach: One hundred six patients with chronic non-responsive pressure skin ulcers, who had previously used galenic dressings, applied without proper therapeutic indication, were included in this study. We administered the WOUND-Q, at time 0 and after 1 month of appropriate therapy, to assess patient-reported outcome measures. Group 1 consisted of 30 patients treated with advanced dressings, Group 2: 22 patients treated with VAC therapy, and Group 3: 30 patients continuing conventional galenic dressings (Control group). Statistical analysis allowed us to analyze QoL changes over time and to compare WOUND-Q Group 1 and 2 deltas with those of Group 3. The study followed the STROBE statement. Results and Innovation: In all the scales evaluated (Assessment, Drainage, Smell, Life impact, Psychological, Social, Sleep and Dressing), there were significant improvements in mean values for Groups 1 and 2. Kruskal-Wallis tests with Dunn's multiple-comparisons tests and Brown-Forsythe and Welch Analysis of Variance tests demonstrated significant differences between deltas of Group 1 and Group 2 compared with those of Group 3 for most scales analyzed. Conclusions: Administration of the WOUND-Q demonstrated that the application of advanced dressings alone or VAC therapy alone positively affects the QoL of patients with chronic nonresponsive pressure wounds, in comparison with galenic dressings alone. The WOUND-Q has been shown to be a valid tool in studying changes in QoL of these patients.

Development of a serum neutralization assay to detect Pteropine Orthoreovirus Indonesia/2010 neutralizing antibodies.

Pteropine Orthoreoviruses (PRVs) are fusogenic bat-borne orthoreoviruses that cause flu-like upper respiratory tract infections in humans. The presence of this group of viruses in bats and humans has been well documented in areas where their biological reservoirs - fruit bats (family Pteropodidae) - live densely. In the present study, a serum neutralization (SN) assay to detect neutralizing antibodies against PRV Indonesia/2010 isolate was set up and used to assess the seroprevalence of this virus in Italian domestic animals. The new developed assay was able of detecting PRV neutralizing antibodies in the hyper-immune polyclonal serum produced in rabbits (titer of 1:160). The negative serum was negative at all tested dilutions. No cross-reactions have been evidenced neither against reference MRVs nor against their respective hyper-immune sera. Eight hundred and fifty-three serum samples collected from 524 bovines, 271 small ruminants, and 58 horses (all used as sentinel animals in the Bluetongue and West Nile disease National surveillance program) were also tested with the new developed SN assay. According to the results of this survey, neither PRV nor PRV cross- reacting viruses antibodies have been demonstrated in Italian domestic animals. However, the new developed SN assay could be a very valuable diagnostic tool to detect infection in animals and humans.
