Objective: To investigate the prevalence, characteristics, and preventive status of skin injuries caused by personal protective equipment (PPE) in medical staff. Approach: A cross-sectional survey was conducted online for understanding skin injuries among medical staff fighting COVID-19 in February 8-22, 2020. Participants voluntarily answered and submitted the questionnaire with cell phone. The questionnaire items included demographic data, grade of PPE and daily wearing time, skin injury types, anatomical sites, and preventive measures. Univariable analyses and logistic regression analyses were used to explore the risk factors associated with skin injuries. Results: A total of 4,308 respondents were collected from 161 hospitals and 4,306 respondents were valid. The overall prevalence of skin injuries was 42.8% (95% confidence interval [CI] 41.30-44.30) with three types of devicerelated pressure injuries, moist-associated skin damage, and skin tear. Co-skin injuries and multiple location injuries were 27.4% and 76.8%, respectively. The logistic regression analysis indicated that sweating (95% CI for odds ratio [OR] 87.52-163.11), daily wearing time (95% CI for OR 1.61-3.21), male (95% CI for OR 1.11-2.13), and grade 3 PPE (95% CI for OR 1.08-2.01) were associated with skin injuries. Only 17.7% of respondents took prevention and 45.0% of skin injuries were treated. Innovation: This is the first cross-sectional survey to understand skin injuries in medical staff caused by PPE, which is expected to be a benchmark. Conclusion: The skin injuries among medical staff are serious, with insufficient prevention and treatment. A comprehensive program should be taken in the future.

Support surfaces remain an integral component of pressure injury prevention and treatment. Recent research and new technologies coupled with new standards testing created a need for revision of past terms and definitions related to support surfaces. These terms and definitions have been developed to provide a common understanding of terms that refer to basic physical concepts, design considerations, and product characteristics. Thus, the purpose of this document is to provide a glossary of terms and definitions that are specific to the language used within the Support Surface Standards Initiative, and serve as a lexicon to facilitate and provide clarity of understanding regarding performance evaluation and the standardized testing protocols. Based on the work of the Support Surface Standards Initiative (S3I) of the NPUAP, new terms and definitions were added, and all were compiled into an alphabetical list to facilitate ease of use. While this is a comprehensive and inclusive list, periodic review and revision is required. The bibliography, of necessity, includes classic references for terms for which the definitions have not changed. The foundational definition of a support surface used in this document is: "A specialized device for pressure redistribution designed for management of tissue loads, micro-climate, and/or other therapeutic functions (e.g. any mattresses, integrated bed system, mattress replacement, overlay, or seat cushion, or seat cushion overlay)."

OBJECTIVE To explore the relationship between wearing protective masks and goggles and skin injuries in medical staff during the COVID-19 pandemic. METHODS Researchers conducted a cross-sectional, multicenter online survey. Respondents voluntarily completed the questionnaire on their smartphones. Ordinal and multinomial logistic regressions were used to identify factors related to skin injuries. RESULTS In total, 1,611 respondents wore protective masks combined with goggles in 145 hospitals in China; 1,281 skin injuries were reported (overall prevalence, 79.5%). Multiple concomitant skin injuries (68.5%) and injuries in four anatomic locations (24.0%) were the most common, followed by injuries in three (22.8%), two (21.7%), and one location (11.0%). Multinomial logistic regression indicated that sweating increased the risk of injuries in one to four anatomic locations (95% confidence interval for odds ratio 16.23-60.02 for one location and 38.22-239.04 for four locations), and wearing an N95 mask combined with goggles and a daily use longer than 4 hours increased the risk of injuries in four locations (95% confidence interval for odds ratio 1.18–5.31 and 1.14–3.93, respectively). CONCLUSIONS The prevalence of skin injuries among medical staff wearing protective masks combined with goggles was very high. These were mainly device-related pressure injuries, moisture-associated skin damage, and skin tears. The combination of various factors resulted in skin injuries at multiple sites. Preventing and managing sweating should be a focus for medical staff who wear protective masks combined with goggles for more than 4 hours.

ObjectivesTo explore the association between N95 respirator wearing and device-related pressure injury (DRPI) and to provide a basis for protecting medical staff from skin injuries.DesignA cross-sectional, multicentre study.Setting and participantsMedical staff of 60 hospitals were selected from 145 designated medical institutions located in the epidemic area where the patients with COVID-19 were treated in China.ResultsIn total, 1761 respondents wore N95 respirators (use alone 20.8%; combination use 79.2%), and the prevalence of DRPI was 59.2% (95% CI 56.93 to 61.53). A daily wearing time of >4 hours (OR 1.62, 95% CI 1.11 to 2.35), wearing a N95 respirator in combination with goggles both with the presence of sweating (OR 13.40, 95% CI 7.34 to 23.16) and without the presence of sweating (OR 0.80, 95% CI 0.56 to 1.14) and wearing only a N95 respirator with the presence of sweating (OR 9.60, 95% CI 7.00 to 13.16) were associated with DRPI. A correspondence analysis indicated that if there was no sweating, regardless of whether the N95 respirator was worn by itself or in combination with goggles, single-site DRPI mainly occurred on the nose bridge, cheek and auricle. If there was sweating present, regardless of whether the N95 was worn by itself or in combination with goggles, multiple DRPI sites occurred more often on the face.ConclusionsThe prevalence of DRPI among medical staff caused by N95 respirators was very high, which was mainly associated with a longer daily wearing time and interaction with sweating. The nasal bridge, cheeks and auricles were the primary protection locations found.

Background and aimsAlong with an aging population, exploring the impact of oral health on holistic health and determining exact outcomes in elderly individuals are important in both scientific research and clinical practice. Significant increase in the number of systematic reviews shows that oral health can directly or indirectly affect the overall health of elderly people physically, mentally and socially. To systematically collate, appraise, and synthesize the current evidence, we carried out an umbrella review of the impacts of oral health on holistic health in elderly individuals.MethodsA systematic reviews and meta-analyses search was performed in the major databases PubMed, MEDLINE, Web of Science and the Cochrane Library from inception to February 1, 2022, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The JBI (Joanna Briggs Institute) Critical Appraisal Checklist for Systematic Reviews and Research Syntheses was referred to assess methodological quality, and the GRADE (Grading of Recommendations, assessment, Development, and Evaluation working group classification) was used to assess the quality of evidence for each outcome included in the umbrella review.ResultsOut of 1,067 records, a total of 35 systematic reviews were included. Respiratory diseases, malnutrition, age-related oral changes, frailty, cognitive impairment, depression and poor quality of life were identified as seven key outcomes that affect the physical, mental and social health of elderly individuals. Meanwhile, three intervention measures of oral health were summarized as (i) more rigorous and universal scales, (ii) dental cleaning and denture installation, and (iii) improving self-awareness regarding oral care.ConclusionsEvidence showed that oral health can significantly affect holistic health, and the diverse oral diseases directly lead to multiple health outcomes in elderly individuals. Clear high-quality evidence revealed that oral health is strongly associated with seven health outcomes covering physical, mental, and social levels, which directly corresponds to holistic health, and impacts the quality of life of elderly individuals. Such the results remind the importance of oral care in public health, and further studies need to be conducted to verity more specific association between oral health and other chronic diseases.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/#recordDetails, identifier: CRD42022315315.

Background: Assessing the effectiveness and safety of acupuncture therapy for treating patients with radiotherapy-induced nausea and vomiting (RINV) is the main purpose of this systematic review protocol. Methods: The following electronic databases will be searched from inception to Sep 2019: Cochrane Central Register of Controlled Trials, PubMed, Web of Science, EMBASE, China National Knowledge Infrastructure, Traditional Chinese Medicine, Chinese Biomedical Literature Database, Wan-Fang Database, and Chinese Scientific Journal Database.
