Effectiveness of 2 Pretreatment Methods in Antifogging of Goggles in a COVID-19 Isolation Ward: A Randomized Controlled Trial.

INTRODUCTION: This study aimed to compare the effectiveness of the pretreatment of goggles with iodophor solution and antibacterial hand sanitizer to reduce the fogging of goggles. METHODS: A total of 90 health care workers were divided into a control group (n = 30), an iodophor solution group (n = 30), and an antibacterial hand sanitizer group (n = 30). This study evaluated the degree of fogging of goggles and the light transmission, comfort, eye irritation, and the impact of goggles on the medical work of staff. RESULTS: The antibacterial hand sanitizer group had the lowest amount of goggle fogging and the most transparent view. Participants in the control group reported the worst light transmission and comfort level, followed by the iodophor solution group. In contrast, the goggles in the antibacterial hand sanitizer group had the best light transmission and comfort level. The iodophor solution group participants reported more eye irritation. Participants in the control group reported that the goggles severely impacted their medical work, with a less severe impact reported by the iodophor solution group. The antibacterial hand sanitizer group did not report any impact on their medical work. DISCUSSION: When the goggles were internally coated with antibacterial hand sanitizer solution (diluted 1:1 with distilled water), the antifog effect was significant. Moreover, the goggles treated with antibacterial hand sanitizer had a clearer field of vision, were reported as non-irritating to the eyes, and significantly improved the efficiency of COVID-19 health care workers, including emergency nurses and providers.

Systemic review about the effect of the application of continuity nursing in community diabetes / 中国实用护理杂志

Objective Systemic analysis the effect of the application of continuity nursing in community diabetes.Methods Retrieve documents from the PubMed,Cochrane Library,EMBASE,Science Direct,CBM,WANFANG Data and CNKI.Dating from the dates of establishment to May,2014.Randomized controlled trials (RCTs) on continuity of patient care for patients with diabetes were included.Two reviewers independently screened the literature according to the inclusion and exclusion criteria,extracted the data and assessed the quality of the included studies,and then meta-analysis was performed by RevMan 5.1 software.Results 5 RCTs (156 cases with diabetes) were involved into this Meta-analysis.The experimental group was superior to the control group in FBG,2h PBG,HbA1c and the level of treatment compliance,with statistically significant differences,P＜0.05.The descriptive analysis showed that the differences in the score of diabetes knowledge and the quality of life were statistically significant,P＜0.05,because the data could not be converted.Conclusions The continuity nursing can improve the compliance and the quality of life of community diabetes,ameliorate certain biochemical indicators.Study of large sample and RCTs should be take because of the existence of some restraining factors.

Chlamydia pneumoniae as a causative factor of ankylosing spondylitis / 中华临床感染病杂志

Objective To investigate the association of chlamydia pneumoniae infection with ankylosing spondylitis (AS).MethodsSerum samples were obtained from 33 AS patients and 22 healthy controls.Enzyme-linked immunosorbent assay (ELISA) was applied to mearsure serum anti-Chlamydia pneumoniae antibodies (IgM/IgG),while immunofluorescence assay (IFA) was used to detect Chlamydia pneumoniae LPS antigen,and polymerase chain reaction (PCR) was used to amplify Chlamydia pneumoniae DNA in peripheral blood cells. Immunohistochemistical technique was applied to examine Chlamydia pneumoniae LPS antigen in synovial tissue from another 9 AS patients who received total hip replacement and 13 patients with comminuted femoral fractures.ResultsThe positive rates of Chlamydia pneumoniae IgM,LPS antigen and chlamydia pneumoniae DNA were higher in AS patients than those in healthy controls (78.8％ vs 22.7％,x2 =16.867,P =0.000; 66.7％ vs 31.8％,x2 =6.431,P =0.011; 33.3％ vs 9.1％,x2 =4.298,P =0.038).Chlamydia pneumoniae DNA positive rate was correlated with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels (Z =-2.774 and -2.829,P =0.004).In synovial tissues,chlamydial LPS-containing inflammatory cells were observed in 77.8％(7/9) AS patients,while those in fracture patients was 30.8％ ( 4/13 ) ( P =0.08 ).Conclusion Chlamydia pneumoniae infection is common in blood circulation and joint cavity of AS patients and may be associated with the pathogenesis of AS.
