Since December 2019, the medical staff fighting against COVID‐19 frequently reported the device‐related pressure injury (DRPI) caused by personal protective equipment (PPE). We conducted a cross‐sectional survey online to investigate the prevalence and characteristics of DRPI among medical staff. Univariate and multivariate logistic regression analyses were employed to explore the risk factors associated with DRPI. A total of 4308 participants were collected and 4306 participants were valid from 161 hospitals in China. The overall prevalence of DRPI caused by PPE among medical staff was 30.03% (95% CI 28.69%‐31.41%). The prevalence of male was more than that of female (42.25%, 95% CI 37.99‐46.51% vs 26.36%, 95% CI 26.93‐29.80%, P <.001).The categories were mainly stages 1 and 2, and the common anatomical locations were nose bridge, cheeks, ears, and forehead. Logistic regression analysis revealed that the risk factors were sweating (OR = 43.99, 95% CI 34.46‐56.17), male (OR = 1.50, 95% CI 1.12‐1.99), level 3 PPE (OR = 1.44, 95% CI 1.14‐1.83), and longer wearing time (OR = 1.28, 95% CI 0.97‐1.68). The prevalence of DRPI was high among medical staff wearing PPE against COVID‐19, and the risk factors were sweating, male, wearing level 3 PPE, and longer wearing time. Comprehensive preventive interventions should be taken. [ABSTRACT FROM AUTHOR]

Cerasus humilis (Bge.) Sok (C. humilis) is a wild fruit tree endemic to China. It mainly grows on saline land and often suffers from osmotic stress. Biophotons are ultraweak luminescence (UWL) radiations that are closely related to various biological processes and activities. UWL emission essentially originates from the oxidative stress process of organisms. However, it is unclear whether UWL production is related to the redox state of chloroplasts. Therefore, to understand the UWL emission mechanism in plants, we studied the effect of salt stress on the photosystem (PS) activity and UWL of C. humilis leaves and analyzed the correlation between PS activity and UWL. The results showed that salt stress severely inhibited the PS activity of C. humilis leaves and oxygen-evolving complex, damaged the integrity of the thylakoid membrane, decreased the photochemical efficiency of PSII, and hindered the Q A -Q B electron transfer. At the same time, the intensity of UWL also decreased. Further, correlation analyses of PS activity indices and UWL showed that UWL was significantly correlated with main parameters of photosystem activity such as PSII the maximum photochemical efficiency (F v /F m) and photosynthetic performance index based on absorbed light energy (PI ABS), as well as the absorption, capture, and transfer of energy in the unit reaction center and unit leaf section. These results indicated that the PS activity of C. humilis was related to the production of UWL, and the intensity of UWL decreased with the decrease in PS activity. • Salt stress reduced the ultra-weak luminescence (UWL) intensity of Cerasus humilis leaves. • Salt stress inhibits the photosystem activity of Cerasus humilis leaves and damaged the integrity of thylakoid membrane. • Under salt stress, the UWL intensity of Cerasus humilis leaves is closely related to the photosystem activity.

Objective: The objective of this study was to investigate the effects of different types of faecal collection devices on incontinence-associated dermatitis (IAD) in critically ill patients with faecal incontinence., Review Method Used: This was a systematic review and meta-analysis., Data Sources: A comprehensive electronic literature search was performed in PubMed, Embase, Cumulative Index of Nursing and Allied Health Literature (CINAHL), the Cochrane library, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and WeiPu. All the databases were searched from their inception to July 31, 2019, and the data were updated on November 2, 2019., Review Methods: Randomised controlled trials (RCTs) and quasi-experimental studies were included. Participants were critically ill patients with faecal incontinence, and the interventions involved care with faecal collection devices. Comparisons were usual care, and the outcome was the incidence of IAD. Odds ratios (ORs) were used to calculate the pooled effect sizes. Heterogeneity was tested using the inconsistency index (I 2 ) method., Results: Nineteen studies were included in this systematic review including 16 RCTs and three quasi-experimental studies. Twelve RCTs were included in the meta-analysis, which showed that the use of faecal collection devices significantly reduced the incidence of IAD. Subgroup analyses based on device type showed significant effects for anal pouch collection devices (OR, 0.14; 95% confidence interval [CI], 0.07-0.26; P < 0.00001), anal pouch connected to negative-pressure suction devices (OR, 0.18; 95% CI, 0.08-0.42; P < 0.00001), anal catheter/tube collection devices (OR, 0.24; 95% CI, 0.13-0.44; P < 0.00001), and anal catheter/tube connected to negative-pressure suction devices (OR, 0.20; 95% CI, 0.07-0.59, P < 0.00001)., Conclusions: Faecal collection devices can reduce the incidence of IAD in critically ill patients with faecal incontinence. It is suggested that when using a device to care for critically ill patients with faecal incontinence, an anal pouch connected to continuous low-negative-pressure suction device should be preferred. Further high-quality research is still needed regarding anal catheter/tube collection devices and anal catheter/tube connected to continuous low-negative-pressure suction devices., Competing Interests: Conflict of interest The authors declare no conflict of interest, (Copyright © 2020 Australian College of Critical Care Nurses Ltd.
