ZO-1 Serum Levels as a Potential Biomarker for Psychotic Disorder.

OBJECTIVE: There are limited studies in the literature on the relationship between intestinal and blood-brain barrier permeability and the etiology of schizophrenia. We hypothesized that the difference in serum ZO-1 levels in patients with schizophrenia may affect the severity of the disease. The aim of this study was to investigate the role of changes in serum ZO-1 concentrations in the etiopathogenesis of patients with schizophrenia. METHODS: A total of 46 patients, 34 with schizophrenia, 12 with a first psychotic attack, and 37 healthy controls, were included in the study. Symptom severity was determined by applying the Positive and Negative Syndrome Scale and the Clinical Global Impression-Severity Scale. Serum ZO-1 levels were measured from venous blood samples. RESULTS: Serum ZO-1 levels were higher in patients with psychotic disorder compared to healthy controls. There was no statistically significant difference between the groups in the first psychotic attack group and the schizophrenia patients. There was a statistically significant positive correlation between serum ZO-1 levels and Positive and Negative Syndrome Scale positive symptom score. CONCLUSIONS: These findings regarding ZO-1 levels suggest that dysregulation of the blood-brain barrier in psychotic disorder may play a role in the etiology of the disorder.

Home-based management on hospital re-admission rates in COPD patients: A systematic review.

AIM: To determine the impact of home-based management on hospital re-admission rates in patients with chronic obstructive pulmonary disease (COPD). DESIGN: Systematic review methodology was utilized, combining meta-analysis, where appropriate, or a narrative analysis of the data from included studies. DATA SOURCES: Electronic databases CINAHL, MEDLINE, PubMed, Embase and SAGE journals for primary papers, 2015 to 2021, were searched between December 2020 and March 2021, followed by hand-searching key journals, and reference lists of retrieved papers. METHODS: The review followed the guidance of PRISMA. Data were extracted using a predesigned data extraction tool. Quality appraisal was undertaken using RevMan 'risk of bias' tool. Meta-analysis was undertaken using RevMan software. RESULTS: This review integrates evidence from eight studies, five Random Control Trials, two observational studies and one retrospective study. The studies span three continents, Asia, Europe and North America, and include 3604 participants with COPD. Home-based management in patients with COPD resulted in a statistically significant reduction in rates of hospital readmission. For the outcomes, length of stay and mortality, while slightly in favour of home-based management, the results were not statistically significant. CONCLUSION: Given the burden of COPD on healthcare systems, and crucially on individuals, this review identified a reduction in hospital re-admission rate, a clinically important outcome. IMPACT: This study focused on the impact on hospital re-admission rates among the COPD patient cohort when home-based management was involved. A statistically significant reduction in rates of re-admission to the hospital was identified. This is positive for the patient, in terms of hospital avoidance, and reduces the burden on hospital systems. Further research is needed to determine the impact on cost-effectiveness and to quantify the most ideal type of care package that would be recommended for home-based management.

A systematic review of the impact of compression therapy on quality of life and pain among people with a venous leg ulcer.

AIM: To gain a greater understanding of how compression therapy affects quality of life, this systematic review appraised existing published studies measuring the impact of compression therapy on health quality of life (HRQoL), and pain, among people with venous leg ulcers (VLU). METHOD: Five databases were searched, and two authors extracted data and appraised the quality of selected papers using the RevMan risk of bias tool. Due to heterogeneity in the types of compression and instruments used to evaluate HRQoL, meta-analysis was not appropriate; thus, a narrative synthesis of findings was undertaken. RESULTS: Ten studies were included, 9 RCTs and one before-after study. The studies employed nine different HRQoL tools to measure the impact of a variety of compression therapy systems, with or without an additional exercise programme, versus other compression systems or usual care, and the results are mixed. With the use of the Cardiff Cardiff Wound Impact Schedule, the SF-8 and the SF-12, study authors found no differences in QoL scores between the study groups. This is similar to one study using QUALYs (Iglesias et al., 2004). Conversely, for studies using EuroQol-5D, VEINES-QOL, SF-36 and CIVIQ-20 differences in QoL scores between the study groups were noted, in favour of the study intervention groups. Two further studies using QUALYs found results that favoured a two-layer cohesive compression bandage and the TLCCB group, respectively. Results for the five studies that assessed pain are also mixed, with one study finding no difference between study groups, one finding that pain increased over the study period and three studies finding that pain reduced in the intervention groups. All studies were assessed as being at risk of bias in one or more domains. CONCLUSION: Results were varied, reflecting uncertainty in determining the impact of compression therapy on quality of life and pain among people with a venous leg ulcer. The heterogeneity of the compression systems and the measures used to evaluate HRQoL make it a challenge to interpret the overall evidence. Further studies should strive for homogeneity in design, interventions and comparators to enhance both internal and external validity.

2D:4D ratio, alexithymia, impulsivity, aggression, and ADHD in men with opioid and methamphetamine use disorders: A comparative analysis with healthy controls.

Substance use disorder is an important mental health problem with increasing frequency. This study aims to investigate the 2D:4D ratio, Dr-I values (right-left differences), alexithymia, aggression, impulsivity, and attention deficit hyperactivity disorder (ADHD) symptoms in male patients with methamphetamine use disorder (MUD), opioid use disorder (OUD), and healthy controls. The study included a total of 57 male patients diagnosed with OUD, 42 male patients diagnosed with MUD, and 72 healthy male controls. The study indicated that the OUD and MUD patients were significantly different from the healthy controls in terms of the 2D:4D ratio, alexithymia, impulsivity, aggression, and ADHD. Compared to healthy controls, 2D:4D ratios, and Dr-I values were lower in OUD and MUD patients. OUD and MUD patients had higher scores of alexithymia, impulsivity, aggression, and ADHD compared to healthy controls. There were statistically significant negative correlations between the right-hand 2D:4D ratios and the ADHD, impulsivity, alexithymia and aggression scores and a significant negative correlation between Dr-I scores and the impulsivity scores of MUD and OUD patients. These findings contribute to the existing literature examining the complex relationship between prenatal testosterone exposure, substance use disorders and related psychological traits.

A systematic review of patient risk factors for complications following stoma formation among adults undergoing colorectal surgery.

BACKGROUND: Stoma formation is a commonly performed procedure both during and following colorectal surgery. When designed correctly, stomas can dramatically improve patients' quality of life, but the reverse may occur when complications arise. Given the significant negative impact of complications following stoma formation, understanding risk factors that may be mitigated pre-operatively is important. METHOD: A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in May 2022. Data was extracted and a narrative synthesis undertaken. The evidence-based librarianship (EBL) checklist assessed the methodological quality of the included studies. The systematic review includes various research designs such as randomised controlled trials (RCT), case-control studies, and observational cohort studies written in English. Reviews, conference papers, opinion papers, and those including participants < 18 years old were excluded. No restrictions on the date of publication and study setting were applied. RESULTS: This review included 17 studies, conducted between 2001 and 2020. The study designs were prospective audit, prospective analysis, retrospective analysis, longitudinal analysis and multivariate analysis of self-reported questionaires/surveys. Twenty-two possible risk factors for the development of stoma complications following stoma formation were identified. These include demographical risk factors, underlying medical condition, type of surgery, elective vs emergency surgery, stoma factors, surgical factors, indications for surgery and factors which may impact healing. Furthermore, high BMI, emergency surgery, and stoma type were identified as the most frequently occurring risk factors. CONCLUSION: Given the large number of risk factors identified, the implementation of a risk stratification tool may decrease the incidence and prevalence of stoma complication development. This, in turn, would decrease the associated healthcare-related costs, and negative impact on mortality, length of stay and quality of life.

The impact of brain tissue oxygenation monitoring on the Glasgow Outcome Scale/Glasgow Outcome Scale Extended in patients with moderate to severe traumatic brain injury: A systematic review.

BACKGROUND: Traumatic brain injuries (TBIs) are one of the leading causes of death or long-term disability around the world. As a result of improvements in supportive care, patients are surviving more severe insults with more pronounced dependency on their families, hospitals, and long-term care facilities. The introduction of brain tissue oxygenation (PbtO2) monitoring aims to recognize episodes of reduced cerebral perfusion with and without associated increased intracranial pressure (ICP). AIM: The aim of this review is to determine the impact of PbtO2 on the Glasgow Outcome Scale/Glasgow Outcome Scale Extended (GOS/GOSE) in patients with moderate to severe TBI. DESIGN: Systematic review with narrative and meta-analysis. All original research in which adult patients undergoing PbtO2 were compared with a control group of traditional ICP/cerebral perfusion pressure (CPP) monitoring. Both randomized controlled trials and observational studies were included in this review. METHODS: Databases were searched in September 2022. The primary outcome of the review was the impact of PbtO2 monitoring on GOS/GOSE, while secondary outcomes were mortality and length of stay (LOS) in the intensive care unit (ICU). RESULTS: Seven studies with a combined number of 770 patients were included in the review. These patients were adults ≥16 years of age. Only two of the studies included found a statistically significant association between PbtO2 monitoring and improved long-term neurological outcomes in patients with TBI (p = .01, p < .01). A meta-analysis of the secondary outcomes identified an associated reduction of mortality in favour of the group treated with PbtO2 monitoring (p < .0001). Results from studies examining LOS in ICU have demonstrated an associated increase of LOS in ICU in patients treated with PbtO2-guided therapy. CONCLUSION: From the studies included in this review, only two found a statistically significant association between PbtO2 monitoring and long-term outcomes. It is unclear whether PbtO2 goal-directed therapy has a positive impact on the long-term neurological functions and mortality of patients suffering from TBI. A multicentre randomized controlled trial may provide further evidence, but not necessarily conclusive. RELEVANCE TO CLINICAL PRACTICE: Further research is warranted to determine the efficacy of the introduction of this new monitoring system to guide local policy change.

Assessing nurses' attitudes towards pressure ulcer prevention: an updated systematic review.

OBJECTIVE: The aim of this systematic review was to critically appraise and synthesise the existing research literature pertaining to nurses' attitudes toward pressure ulcer (PU) prevention. METHOD: The systematic review presented in our paper serves as an updated version of the definitive review conducted by Avsar et al. in 2019. Using systematic review methodology, we considered published quantitative studies focusing on nurses' attitudes toward PU prevention as measured using psychometric tests. The search was conducted in April 2022, using PubMed, CINAHL, Scopus, Cochrane and EMBASE databases, and returned 454 records, of which 35 met the inclusion criteria. Data were extracted using a pre-designed extraction tool and all included studies were quality appraised using the evidence-based librarianship (EBL) appraisal checklist. RESULTS: In most studies, distinct measurement instruments were used for measuring nurses' attitudes toward the prevention of PUs: the Moore and Price Attitude Scale and the Attitude towards Pressure Ulcer Prevention Instrument (APuP). In this first update, the mean attitude score was 69% (±14%, range: 33.6-89%). A separate analysis of the new studies alone included in this first update (n=14) indicated a mean attitude score of 62.25% (±17.9%; median: 14%), suggesting a 10.75% lower mean attitude score. In total, 46% (n=16) yielded a score ≥75%. Conversely, Avsar et al. in 2019, 86% (n=18) of studies yielded positive attitude results. Studies from the Middle East show the lowest mean attitude score (mean 55%; ±15%; median 53%; n=9), with studies from Europe displaying the highest mean attitude score (mean 79%; ±6%; median 79%; n=12). CONCLUSION: The findings suggest that, overall, nurses are relatively positively disposed toward PU prevention. However, there are differences across continents. It is important to highlight also that the nurses have difficulties reflecting this positive attitude into actual preventative strategies.

The impact of healthcare assistant education on pressure ulcer prevention: a systematic review.

OBJECTIVE: To investigate the impact of education for healthcare assistants (HCAs) on their knowledge and skills in pressure ulcer (PU) prevention and on the incidence of PUs. A secondary aim was to evaluate education methodologies used in PU prevention programmes. METHOD: Using systematic review methodology, key databases were searched with no limitations on date of publication. The search was conducted in November 2021 using the following databases: CINAHL, Embase, Scopus, MEDLINE, Cochrane Wounds Group Specialist Register and Cochrane Central Register of Controlled Trials. Inclusion criteria focused on studies that employed the use of education as an intervention, delivered to HCAs in any setting. The PRISMA guidelines were followed. The methodological quality of the studies was evaluated using the Evidence-Based Librarianship (EBL) appraisal checklist. Data were analysed using narrative analysis and meta-analysis. RESULTS: The systematic search yielded an initial 449 records, of which 14 studies met the inclusion criteria. Outcome measures of HCA knowledge scores were reported in 11 (79%) studies. Outcome measures related to PU prevalence/incidence were reported in 11 (79%) studies. An increase in knowledge scores of HCAs post-educational intervention was reported in five (38%) studies. A significant reduction in PU prevalence/incidence rates post-educational intervention was reported in nine (64%) studies. CONCLUSION: This systematic review affirms the benefits of education of HCAs on their knowledge and skills of PU prevention, and on PU incidence. The results must be treated with caution due to quality appraisal issues of included studies.

Assessing the healthcare costs associated with venous leg ulcer compression bandages - A scoping review.

AIM: To determine the monetary costs identified in economic evaluations of treatment with compression bandages among adults with venous leg ulcers (VLU). METHOD: A scoping review of existing publications was conducted in February 2023. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. RESULTS: Ten studies met the inclusion criteria. To place the costs of treatment into context, these are reported in conjunction with the healing rates. Three comparisons were made: 1.4 layer compression versus no compression (3 studies). One study reported that 4 layer compression was more expensive than usual care (£804.03 vs £681.04, respectively), while the 2 other studies reported the converse (£145 vs £162, respectively) and all costs (£116.87 vs £240.28 respectively). Within the three studies, the odds of healing were statistically significantly greater with 4 layer bandaging (OR: 2.20; 95% CI: 1.54-3.15; p = 0.001).; 2.4 layer compression versus other compression (6 studies). For the three studies reporting the mean costs per patient associated with treatment (bandages alone), over the treatment period, analysis identified a mean difference (MD) in costs for 4 layer vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) of -41.60 (95% CI: 91.40 to 8.20; p = 0.10). The OR of healing for 4 layer compression vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 0.70 (95% CI: 0.57-0.85; p = 0.004). For 4 layer vs comparator 2 (2 layer compression) the MD is: 14.00 (95% CI: 53.66 to -25.66; p < 0.49). The OR of healing for 4 layer compression vs comparator 2 (2 layer compression) is: 3.26 (95% CI: 2.54-4.18; p < 0.00001). For comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) vs comparator 2 (2 layer compression) the MD in costs is: 55.60 (95% CI: 95.26 to -15.94; p = 0.006). The OR of healing with Comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 5.03 (95% CI:4.10-6.17; p < 0.00001). Three studies presented the mean annual costs per patient associated with treatment (all costs). The MD is 172 (150-194; p = 0.401), indicating no statistically significant difference in costs between the groups. All studies showed faster healing rates in the 4 layer study groups. 3. Compression wrap versus inelastic bandage (one study). Compression wrap was less expensive than inelastic bandage (£201 vs £335, respectively) with more wounds healing in the compression wrap group (78.8%, n = 26/33; 69.7%, n = 23/33). CONCLUSION: The results for the analysis of costs varied across the included studies. As with the primary outcome, the results indicated that the costs of compression therapy are inconsistent. Given the methodological heterogeneity among studies, future studies in this area are needed and these should use specific methodological guidelines to generate high-quality health economic studies.

Pressure Injury Prevalence and Risk Factors: A National Multicenter Analytical Study.

PURPOSE: The purpose of this study was to determine the point prevalence (PP) of general pressure injuries (PIs), hospital-acquired PIs, PI-related risk factors, and PI preventive interventions performed by nurses. DESIGN: Descriptive, multicenter, prospective, analytical study. SUBJECTS AND SETTING: The sample comprised 5088 patients cared for in 13 hospitals in 12 geographic regions of Turkey. Data were collected between November 5, 2018, and July 17, 2019. METHODS: The study was carried out in 2 stages. First, nurses who collected data were trained in the diagnosis of PI, risk assessment, staging, and prevalence studies, and informed about the purpose and methods of the study, including data collection. Second, nurses and researchers who had received training related to data collection for this study conducted a PP study for PIs in their inpatient clinics using the ASSIST II method. The PI Prevalence Study Tool and the Braden Scale for Predicting Pressure Sore Risk were also used during data collection. RESULTS: The PP of general PIs was 9.5%; the prevalence of PIs with hospitalization in intensive care units was 43.2%; medical device-related pressure injuries prevalence was 10.7%. We found that 65.1% of the PIs were acquired after hospital admission. CONCLUSIONS: Similarities exist between PI prevalence in Turkey and reported PI prevalence rates worldwide. However, the prevalence of nosocomial PIs related to intensive care units and the prevalence of all nosocomial injuries were higher than rates previously reported. Based on results, there is a need to develop strategies to reduce the prevalence of nosocomial PIs.

What is the prevalence of chronic venous disease among health care workers? A scoping review.

Chronic venous disease (CVD) occurs because of structural or functional disturbances to the venous system of the lower limbs. Signs and symptoms include leg pain, swelling, varicose veins, and skin changes, with venous ulceration ultimately occurring in severe disease. To assess the prevalence of CVD among health care workers, a scoping review of existing publications exploring the prevalence of CVD among health care workers was conducted in July 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. A total of 15 papers met the inclusion criteria and these formed the basis of the review. Among health care workers, the mean prevalence of CVD was 58.5% and the mean prevalence for varicose veins was 22.1%. There is an increased prevalence of CVD in health care workers when compared with the general population. Therefore, there is a need for early diagnosis and the use of preventative measures to protect health care workers from CVD and varicose vein development.

The Effect of Prophylactic Silicone Dressings on the Incidence of Pressure Injuries on Patients in the Acute Care Setting: A Systematic Review and Meta-analysis.

PURPOSE: To explore the effect of silicone dressings on the prevention of pressure injuries in patients cared for in the acute care setting. Three main comparisons were explored: silicone dressing versus no dressing, all anatomical areas; silicone dressing versus no dressing on the sacrum; and silicone dressing versus no dressing on the heels. METHODS: Using a systematic review methodology, published randomized controlled trials and cluster randomized controlled trials were included. The search was conducted from December 2020 to January 2021 using CINAHL, full text on EBSCOhost, MEDLINE on EBSCOhost, and Cochrane databases. The search returned 130 studies; 10 met inclusion criteria. Data were extracted using a predesigned extraction tool. The Cochrane Collaboration tool was used to assess the risk of bias and the certainty of the evidence was appraised using a software program specifically designed for this purpose. RESULTS: Silicone dressings probably reduce the incidence of pressure injuries compared to no dressings (relative risk [RR]: 0.40, 95% confidence interval [CI]: 0.31-0.53; moderate certainty evidence). Furthermore, silicone dressings probably reduce the incidence of pressure injuries on the sacrum compared to no dressings (RR: 0.44, 95% CI: 0.31-0.62; moderate certainty evidence). Finally, silicone dressings probably reduce the incidence of pressure injuries on the heels compared to no dressings (RR: 0.44, 95% CI: 0.31-0.62; moderate certainty evidence). CONCLUSION: There is moderate certainty evidence of the effect of silicone dressings as a component of a pressure injury prevention strategy. The main limiting factor in the study designs was a high risk of performance and detection bias. Although this is a challenge to achieve in trials such as these, consideration should be given to how the effect of this could be minimized. A further issue is the lack of head-to-head trials that limits clinicians' abilities to determine whether any of the products in this category are more effective than others.

A systematic review of the association between parastomal hernia and sarcopenia.

BACKGROUND: Sarcopenia is a multifactorial loss of muscle mass that can complicate surgical outcomes and increase morbidity and mortality. Parastomal hernias can occur after any surgery requiring stoma formation and is an area of concern as a complication as it can require a second surgery or emergency surgical intervention. AIM: To assess the impact of sarcopenia on parastomal hernia formation in the postoperative period. METHOD: A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in June 2022. Data were extracted, and a narrative synthesis was undertaken. The Crowe Critical Appraisal Tool (CCAT) assessed the quality of the included studies. The systematic review included original research studies, prospective and retrospective designs, and human studies written in English. Reviews, conference papers, opinion papers, and those including participants < 18 years old were excluded. No restrictions on the date of publication and study setting were applied. RESULTS: Nine studies met the inclusion criteria, and these were conducted between 2016 and 2021; 56% (n = 5) used a retrospective study design. The mean sample size was 242.5 participants (SD = ±358.6). No consistent or standardized way of defining sarcopenia or measuring muscle mass was seen between the studies reviewed. However, 45% (n = 4) of the studies reported a significant relationship between sarcopenia and wound healing complications, including an increased incidence of parastomal and incisional hernias. The average CCAT score was 27.56 (SD = ±4.39). CONCLUSION: There is no definitive relationship between sarcopenia and hernia development; however, four studies found a significant relationship between sarcopenia and hernia formation. It must also be considered that different disease processes can cause sarcopenia either through the disease process itself, or the treatment and management. More research and consistent measurements are needed before comparable and consistent outcomes can be compiled.

The role of proinflammatory cytokines in the detection of early pressure ulcer development: a systematic review.

OBJECTIVE: Pressure ulcers (PUs) commonly occur over bony prominences and are notoriously difficult to treat. Proinflammatory cytokines are substances that initiate the inflammatory process preceding PU development. The aim of this review was to assess whether the increased presence of proinflammatory cytokines could potentially be used as an early detection system for PU development. METHOD: A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in August 2020. Data were extracted and a narrative synthesis was undertaken. The evidence-based librarianship (EBL) checklist assessed the methodological quality of the included studies. The systematic review included original research studies, prospective design, and human studies written in English. Retrospective studies, animal studies, conference papers, opinion papers and qualitative methodology were excluded. No restrictions on the date of publication and study setting were applied. RESULTS: The six studies included were conducted between 2015 and 2019, 50% (n=3) used an experimental study design. The mean sample size was 15 participants (standard deviation=1.72). A total of seven proinflammatory cytokines were analysed. Statistically significant differences were found among inflammatory mediators. Overall results showed that the concentration of interleukin (IL)-1α significantly increased in each study. The EBL score varied between 77-88%. In total, 100% (n=6) of the studies scored ≥75%, reflecting validity. CONCLUSION: It is not yet certain that monitoring proinflammatory cytokines represents a noninvasive method that could potentially direct preventative measures to those who are identified as at high risk for developing PUs. IL-1α potentially may be elevated for other health conditions, not just PUs. Future studies are therefore recommended.

The validity and reliability of the Pressure Ulcer Quality of Life instrument: A methodological study.

AIM: This study aimed to adapt the Pressure Ulcer Quality of Life instrument to Turkish and to determine the validity and reliability by using the Rasch model. MATERIALS AND METHODS: This methodological study used forward translation, expert opinion, back translation, pilot testing, and finalization for the language adaptation of the instrument. Prior to back translation, the instrument was assessed by five experts certified in wound care nursing. Then, the comprehensibility of the instrument was tested in the pilot study. The study was conducted between March 2017 and September 2019 at one private, one state, and four university hospitals in Turkey. Eligible participants were patients 18 years of age or older, having pressure injury, and fully conscious. Data were collected from a total of 250 patients by using a demographic and clinical history form, the Pressure Ulcer Quality of Life instrument, and the World Health Organization Quality of Life - Brief Form Turkish scale. The instrument's internal construct validity using the Rasch model, the external construct validity, internal consistency, and test-retest reliability were assessed. RESULTS: The final Turkish version of the Pressure Ulcer Quality of Life self-report instrument differed from the original, comprising 74 items under the following ten subscales: three regarding symptoms, plus one itchiness item; four regarding physical functioning; two regarding psychological well-being, self-consciousness, and appearance; and one regarding social participation. CONCLUSION: The Turkish version of the PU-QOL is a valid, reliable, and widely available instrument for measuring quality of life for patients with pressure injury.

Sub epidermal moisture measurement and targeted SSKIN bundle interventions, a winning combination for the treatment of early pressure ulcer development.

This study aimed to investigate the impact of sub epidermal moisture (SEM) measurement and targeted pressure ulcer (PU) prevention, versus visual skin assessment and usual care, on mean SEM delta scores and early pressure ulcer development in acute hospital patients. A quantitative quasi-experimental observational approach was used. A total of 149 at risk acute hospital patients took part, 78 treatment, and 71 control. SEM deltas were recorded daily for a maximum of 5 days using the SEM Scanner (Bruin Biometrics LLC, Los Angeles, California), on three sites: the sacrum, the right heel, and the left heel, with enhanced and targeted PU prevention interventions occurring in those with an elevated SEM delta scores in the treatment group. Intention to treat analysis was used to guide the final composition of results. SEM PU represents PU development as identified by 2 days of sustained abnormal SEM delta scores, ≥0.5, after day one. The mean number of days completed by participants was just under 4 days, participants had many different comorbidities, with the most common being: hypertension, cancer, and chronic obstructive pulmonary disease. Results showed that following the introduction of SEM guided targeted treatments, participants in the treatment group yielded a statistically significant reduction in mean SEM delta scores (MD: 0.49; 95% CI: 0.59, 0.39; P < .0001), and in the odds of developing a SEM PU (OR: 0.59, 95% CI: 0.24 to 1.00; P = .05). In the treatment group, none of the participants developed a visual PU, whereas, in the control group, 1.41% (n = 1/71) developed a visual PU. Based on all the results, the following is concluded, (1). There was a greater reduction in mean SEM delta scores among those cared for using SEM measurement and targeted PU prevention, versus those cared for using visual skin assessment and usual care, and (2). the mean SEM delta scores was statistically significantly lower at the study end for those who received targeted treatments based on abnormal SEM scores. More research is now needed in other and larger at-risk groups to further validate what was found in this study.

Pressure ulcers in patients with COVID-19 acute respiratory distress syndrome undergoing prone positioning in the intensive care unit: A pre- and post-intervention study.

BACKGROUND: Prone positioning has been widely used to improve oxygenation and reduce ventilator-induced lung injury in patients with severe COVID-19 acute respiratory distress syndrome (ARDS). One major complication associated with prone positioning is the development of pressure ulcers (PUs). AIM: This study aimed to determine the impact of a prevention care bundle on the incidence of PUs in patients with COVID-19 ARDS undergoing prone positioning in the intensive care unit. STUDY DESIGN: This was a single-centre pre and post-test intervention study which adheres to the Standards for Reporting Implementation Studies (StaRI) guidelines. The intervention included a care bundle addressing the following: increasing frequency of head turns, use of an open gel head ring, application of prophylactic dressings to bony prominences, use of a pressure redistribution air mattress, education of staff in the early identification of evolving PUs through regular and rigorous skin inspection and engaging in bedside training sessions with nursing and medical staff. The primary outcome of interest was the incidence of PU development. The secondary outcomes of interest were severity of PU development and the anatomical location of the PUs. RESULTS: In the pre-intervention study, 20 patients were included and 80% (n = 16) of these patients developed PUs, comprising 34 ulcers in total. In the post-intervention study, a further 20 patients were included and 60% (n = 12) of these patients developed PUs, comprising 32 ulcers in total. This marks a 25% reduction in the number of patients developing a PU, and a 6% decrease in the total number of PUs observed. Grade II PUs were the most prevalent in both study groups (65%, n = 22; 88%, n = 28, respectively). In the post-intervention study, there was a reduction in the incidence of grade III and deep tissue injuries (pre-intervention 6%, n = 2 grade III, 6% n = 2 deep tissue injuries; post-intervention no grade III ulcers, grade IV ulcers, or deep tissues injuries were recorded). However, there was an increase in the number of unstageable PUs in the post-intervention group with 6% (n = 2) of PUs being classified as unstageable, meanwhile there were no unstageable PUs in the pre-intervention group. This is an important finding to consider as unstageable PUs can indicate deep tissue damage and therefore need to be considered alongside PUs of a more severe grade (grade III, grade IV, and deep tissue injuries). CONCLUSION: The use of a new evidence-based care bundle for the prevention of PUs in the management of patients in the prone position has the potential to reduce the incidence of PU development. Although improvements were observed following alterations to standard practice, further research is needed to validate these findings. RELEVANCE TO CLINICAL PRACTICE: The use of a new, evidence-based care bundle in the management of patients in the prone position has the potential to reduce the incidence of PUs.

What is the impact of home non-invasive ventilation on the health-related quality of life of patients with chronic obstructive pulmonary disease? A systematic review.

OBJECTIVES: To ascertain the impact of home non-invasive ventilation (NIV) on the health-related quality of life (HRQL) of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). DESIGN: Systematic review. METHODS: A preliminary search of computerised databases (CINAHL, Medline, Clinical Key, Cochrane) was conducted in June 2021, without any limitations on publication date. Inclusion criteria focused on home NIV prescribed for patients with moderate-to-severe COPD. Identified papers were critically appraised for rigour and validity. Data were extracted, analysed, and a narrative synthesis completed. RESULTS: The review included eight studies, including five randomised controlled trials. Variations in the HRQL scores meant that the data were difficult to collate. Nevertheless, the studies did indicate an overall improved HRQL for those using NIV at home. CONCLUSION: This systematic review determines that home NIV does positively impact the HRQL of those with COPD. However, the limited quality of primary studies highlights the need for more in-depth research in this area to bring about optimal standardisation of clinical practice in relation to the use of NIV at home.

A meta-review of the impact of compression therapy on venous leg ulcer healing.

This meta-review aimed to appraise and synthesise findings from existing systematic reviews that measured the impact of compression therapy on venous leg ulcers healing. We searched five databases to identify potential papers; three authors extracted data, and a fourth author adjudicated the findings. The AMSTAR-2 tool was used for quality appraisal and the certainty of the evidence was appraised using GRADEpro. Data analysis was undertaken using RevMan. We identified 12 systematic reviews published between 1997 and 2021. AMSTAR-2 assessment identified three as high quality, five as moderate quality, and four as low quality. Seven comparisons were reported, with a meta-analysis undertaken for five of these comparisons: compression vs no compression (risk ratio [RR]: 1.55; 95% confidence interval [CI] 1.34-1.78; P < .00001; moderate-certainty evidence); elastic compression vs inelastic compression (RR: 1.02; 95% CI: 0.96-1.08; P < .61 moderate-certainty evidence); four layer vs
