Simply, the scanner detects the early appearance of oedema, which is called 'micro-oedema.' Calculation of a 'SEM-delta' value, which compares biocapacitance measurements, acquired across several tissue sites, some of which are healthy and others where the PU may evolve, eliminates potential effects of systemic changes in tissue fluid contents and provides a consistent quantitative measure of the tissue health conditions at the monitored anatomical site. Here, we describe SEM scanner technology, how it operates and has been laboratory tested (in computer simulations, in silico) before commercial launch. We explain why targeting the physical biomarker of oedema leads to the documented success of the SEM scanner in the multiple published clinical trials, proving its ability to early detect PUs that form under intact skin.

The primary objective was to assess the incidence of pressure ulcer (PU) in patients at high risk of PU and lying between 15-20 hours per day on an alternating-pressure mattress overlay (APMO). Secondary objectives were the patient's satisfaction with the comfort of the APMO, patient acceptance of its sound level, and the care team's assessment of its use and the moisture level.

This prospective observational study was conducted in three rehabilitation centres and two nursing homes between June 2016 and March 2017. To be included, patients should not have PU at baseline and present a high risk of PU (Braden score between 10-15). The primary endpoint was the percentage of patients in whom a PU developed over a 35-day period.

A total of 83 patients were included in the study. Neurological disease was responsible for the reduced mobility of 44 (53.7%) patients, 10 patients (12.0%) dropped out (one patient for a serious adverse event (femoral neck fracture) considered not to be related to the APMO, four patients for adverse events, two of which were considered to be related to APMO and five for other reasons, including, in one case, discomfort with the APMO. These patients were considered in the analysis. SR-4370 purchase Over the study period, 1.2% (1/83) (95% confidence interval (CI) 0.03 to 6.53) of patients developed a PU. Patient satisfaction with the comfort of the APMO, patient acceptance of its sound level, and the care team's assessment of its use were considered satisfying for most patients.

Based on the findings of this study of a low incidence of PU in participating patients, the use of an AMPO is recommended in high-risk patients lying for between 15-20 hours a day.

To investigate the feasibility of recruitment, retention, intervention delivery and outcome measurement in a nutritional intervention to promote pressure ulcer healing in an acute setting.

Some 50 tertiary hospital patients with stage II or greater pressure ulcer were randomised to receive either individualised nutritional care by a dietitian, including prescription of wound healing supplements; or standard nutritional care. Relevant nutritional and pressure ulcer (PU) parameters were collected at day 5, 10, 15, 22 and then weekly or until discharge.

The median length of hospital stay was 14 days (1-70) with 29 patients discharged by day 15. There were 24 patients discharged before their PU fully healed. Per cent change in valid PU area and score measures from baseline to day 15 were chosen for outcome data analysis to account for varying initial size and severity of the wound and length of stay. There was a larger percentage reduction in PU measures in the intervention group, but this was not statistically significant. Little difference was found in nutritional intake between the control and intervention groups indicating a requirement to focus on effective delivery of the intervention in future studies. Future studies in the acute setting need to account for length of stay and ideally follow patients until full healing.

Results indicate a positive association with nutrition intervention and PU healing and that a rigorously designed and adequately powered study is feasible.

Several pressure ulcer (PU) risk factors including paralysis and age greater than 70 have been identified, while others such as nutrition are debated. The object of this study is to identify perioperative risk factors that may predict improved outcomes and reduced complications in primary and recurrent PU reconstructions.

A retrospective chart review of patients treated surgically for PUs from 2004 to 2013 at the University of Toledo Medical Center, Toledo, Ohio, US, was completed. Data collected included ulcer and medical history, as well as risk factors, complications and postoperative outcome. Data were statistically analysed for perioperative variances between primary and recurrent ulcers and closure status.

A total of 49 patients with 102 reconstructions were reviewed. Spinal cord injured patients accounted for 90% receiving flap coverage of ulcers. Numerous differences between primary and recurrent ulcers were identified, including ulcer location, patient nutritional status, wound infection, postoperative course and recurrence. Multivariate analysis revealed a flap reconstruction prediction model using creatinine, haematocrit, haemoglobin, and prealbumin that is able to successfully predict closure outcome in 83.6% of cases.

Many factors play a role in the development, course and treatment of PUs. It is vital to understand the role of patient risk factors in the development of PUs, to direct subsequent management and reconstruction, and to prevent future recurrences.

Critically ill patients are at high risk of developing pressure ulcers (PU), with the sacrum and heels being highly susceptible to pressure injuries. The objective of our study was to evaluate the clinical effectiveness of a new multi-layer, self-adhesive soft silicone foam heel dressing to prevent PU development in trauma and critically ill patients in the intensive care unit (ICU).

A cohort of critically ill patients were enrolled at the Royal Melbourne Hospital. Each patient had the multi-layer soft silicone foam dressing applied to each heel on admission to the emergency department. The dressings were retained with a tubular bandage for the duration of the patients' stay in the ICU. The skin under the dressings was examined daily and the dressings were replaced every three days. The comparator for our cohort study was the control group from the recently completed Border Trial.

Of the 191 patients in the initial cohort, excluding deaths, loss to follow-up and transfers to another ward, 150 patients were included in the final analysis.
