- Herein we present non-noble metal single-atom catalysts (SACs) based on carbonized transition metal-doped zeolitic imidazolate frameworks (ZIFs) as stable and efficient electrocatalysts for the hydrogen evolution reaction in acidic media. In this work, earth-abundant metals are embedded in a porous N-rich carbon matrix by pyrolyzing metal-doped ZIF structures and characterized by spectroscopic, microscopic, and electrochemical methods. The complete synthesis of these high surface area SACs was carried out without any solvents and hence offers a promising route for a more sustainable catalyst production and industrial upscaling. As the best-performing catalyst, cobalt SAC illustrated already with a low cobalt loading of <0.3 at.% a substantial increase in activity with an overpotential of -322 mV for -10 mA cm(-2), and high stability during electrolysis at -10 mA cm(-2) for 12 h in acidic media, with only a small decrease of 33 mV to more negative potentials after the initiation period.

- AIM: To explore factors associated with the presence of category I-IV pressure ulcers on the sacrum and heels.DESIGN: Cross-sectional, secondary data analysis using data collected from the Landelijke Prevalentiemeting Zorgproblemen (LPZ) project, a multicentre prevalence study including nursing home residents and community care clients (N = 4842) in the Netherlands in 2017.METHODS: A single binary logistic regression model was designed to identify factors associated with the presence of pressure ulcers. Additionally, a multiple binary logistic regression model including modifiable explanatory factors associated with the presence of pressure ulcers was designed.RESULTS: Impaired mobility, friction and shear (evaluated using the Braden Scale) are significantly associated with the presence of both sacral and heel category I-IV pressure ulcers. Incontinence-associated dermatitis is significantly associated with category I-IV sacral pressure ulcers.CONCLUSION: In pressure ulcer prevention, nursing interventions should focus on frequent repositioning and mobilisation while avoiding exposure of the skin to friction and shear. The need to consider incontinence-associated dermatitis, incontinence and moisture as important factors in pressure ulcer risk assessment is confirmed.IMPACT: Pressure ulcers occur when skin and tissues are deformed between bony prominences and the support surface in a sitting or lying position. They are the result of a complex interaction between direct causal factors and a wide range of indirect factors. Recognition of these factors influence risk assessment guidance and practice. Knowledge of skin-specific factors at the patient level, modifiable by nursing interventions, enable a better targeted and tailored preventive approach.

- PURPOSE: We studied pressure injury (PI) stage II-IV cumulative incidence and the change of PI status in the sacral area of nursing home residents associated with the use of a fully automated pulsating support system air mattress in use for 30 days. We also assessed caregivers', residents', and their family members' experiences and perceptions of mattress comfort and other factors such as pain.DESIGN: Multicenter cohort study.SUBJECT AND SETTING: A convenience sample of 40 residents residing in 10 Belgian nursing homes was recruited.METHODS: Pressure injury classification was confirmed using the European Pressure Ulcer Advisory Panel classification system. The Pressure Ulcer Scale for Healing (PUSH) tool was used to assess and measure PI status change. A comfort assessment was performed at end of the study. Cumulative PI incidence of stages II-IV was calculated, and frequencies and percentages were used to describe the results of the comfort assessments.RESULTS: Residents were allocated to the prevention group (n = 22) and to the treatment group (n = 18). The cumulative PI incidence was 4.5% (n = 1/22) in the prevention group. In the treatment group, the mean score on the PUSH tool decreased from 9.36 to 7.70 during the observation period, indicating an overall improvement. Four of the existing PIs healed, 17 PIs remained stable, and 1 PI deteriorated. The comfort questionnaires were completed by 76 nursing home caregivers, 21 family members, and 11 residents in the 10 participating nursing homes; the mattress comfort was perceived as very good, and pain was noted to decrease.CONCLUSIONS: Low cumulative PI incidence findings were observed with use of the mattress for the prevention of PIs and resulted in improvements in existing PIs, results which are consistent with several existing studies. The majority of the caregivers, residents, and family members evaluated the mattress as comfortable. Future research is needed to corroborate findings in larger randomized clinical trials.

Real-life assessment of chronic rhinosinusitis patients using mobile technology : The mySinusitisCoach project by EUFOREA

- Background: Chronic rhinosinusitis (CRS) is a chronic inflammatory disease associated with a substantial personal and socioeconomic burden. Monitoring of patient-reported outcomes by mobile technology offers the possibility to better understand real-life burden of CRS. Methods: This study reports on the cross-sectional evaluation of data of 626 users of mySinusitisCoach (mSC), a mobile application for CRS patients. Patient characteristics of mSC users were analysed as well as the level of disease control based on VAS global rhinosinusitis symptom score and adapted EPOS criteria. Results: The mSC cohort represents a heterogeneous group of CRS patients with a diverse pattern of major symptoms. Approximately half of patients reported nasal polyps. 47.3% of all CRS patients were uncontrolled based on evaluation of VAS global rhinosinusitis symptom score compared to 40.9% based on adapted EPOS criteria. The impact of CRS on sleep quality and daily life activities was significantly higher in uncontrolled versus well-controlled patients. Half of patients had a history of FESS (functional endoscopic sinus surgery) and reported lower symptom severity compared to patients without a history of FESS, except for patients with a history of more than 3 procedures. Patients with a history of FESS reported higher VAS levels for impaired smell. Conclusion: Real-life data confirm the high disease burden in uncontrolled CRS patients, clearly impacting quality of life. Sinus surgery improves patient-reported outcomes, but not in patients with a history of more than 3 procedures. Mobile technology opens a new era of real-life monitoring, supporting the evolution of care towards precision medicine.

- The primary objective was to study pressure ulcer (PU) category II-IV (including suspected deep tissue injury and unstageable PUs) cumulative incidence and PU incidence density, in a 30day observation period, associated with the use of the CuroCell S.A.M. PRO powered reactive air support surface in nursing home residents at risk for PU development. Secondary objectives were to study (a) PU category I cumulative incidence and PU incidence density and (b) user (caregivers and residents) experiences and perceptions of comfort associated with the use of the support surface under study. A multicentre cohort study was set up in 37 care units of 12 Belgian nursing homes. The sample consisted of 191 residents at risk of PU development (Braden score ≤ 17). The cumulative PU incidence was 4.7% (n = 9). The PU incidence density was 1.7/1000 observation days (9 PU/5370 days). The experience and perceptions of comfort analysis revealed that the CuroCell S.A.M. PRO powered reactive air support surface was comfortable for daily use. The mode of action and the quietness of the pump function had a positive impact on sleep quality. Patient comfort and sleep quality are essential criteria in the selection of a support surface.
