ABSTRACT
Objective@#To systematically investigate the prevalence of anxiety among healthcare professionals during the COVID-19 pandemic, so as to provide the development of evidence-based psychological interventions among healthcare professionals.@*Methods@#The publications pertaining to the prevalence of anxiety among healthcare professionals during the COVID-19 pandemic were retrieved in national and international electronic databases from January 1, 2020 through November 30, 2021, including CNKI, Wanfang Data, VIP, SinoMed, PubMed and Web of Science. The quality of publications was evaluated using the United States Healthcare Research and Quality (AHRQ) quality assessment of included cross-sectional studies, and the pooled prevalence of anxiety was estimated among healthcare professionals using the software Open Meta Analyst version 3.0. The publication bias were evaluated with funnel plots and Begg rank correlation test.@*Results@#Totally 598 publications were retrieved, and 36 eligible publications were enrolled in the final analysis, including 33 Chinese publications and 3 English publications. There were 5 high-quality, 29 moderate-quality and 2 low-quality publications. All investigations pertaining to the prevalence of anxiety among healthcare professionals were conducted in 2020. Totally 19 872 healthcare professionals were investigated, and the prevalence of anxiety was 28.8% (95%CI: 24.0%-33.6%). Subgroup analysis showed that the prevalence of anxiety was 31.9% (95%CI: 17.6%-46.2%) among healthcare professionals from western China, 29.6% (95%CI: (17.8%-41.4%) from central China, and 25.3% (95%CI: 20.2%-30.3%) from eastern China. The prevalence of anxiety was 4.9% (95%CI: 3.3%-6.4%) among male healthcare professionals and 22.9% (95%CI: 17.7%-28.0%) among male healthcare professionals, and the prevalence of anxiety was 21.6% (95%CI: 13.2%-29.9%) among nurses, 5.2% (95%CI: 2.8%-7.5%) among doctors and 4.8% (95%CI: 2.2%-7.4%) among other healthcare professionals. The prevalence of mild, moderate and severe anxiety was 18.6% (95%CI: 14.0%-23.2%), 5.5% (95%CI: 4.1%-6.8%) and 1.9% (95%CI: 1.3%-2.5%), respectively. No publication bias was detected as revealed by funnel plots and Begg rank correlation test, and stable meta-analysis results and heterogeneity test were observed.@*Conclusions@#The prevalence of anxiety is 28.8% among healthcare professionals during the COVID-19 pandemic, and mild anxiety is predominant. A high prevalence rate of anxiety is seen female healthcare professionals and nurses, who should be given a high priority and timely psychological interventions
ABSTRACT
Objective To evaluate the effectiveness of computer aided design (CAD) and three bit printing in the management of orthognathic surgery.Methods A total of 5 cases of patients with jaw deformity were involved in this study;jaw teeth and CT scanning laser scanning hefore surgery,virtual surgery design of 3D reconstruction and fusion data were analyzed,according to the design scheme of double jaw surgery combined with genioplasty;design and 3D printing of maxillary Le Fort Ⅰ osteotomy,genioplasty titanium alloy resin osteotomy and positioning guide,sagittal split ramus osteotomy by 3D printing and plate technology were used in this approach.The postoperative results were compared with the surgical planning by three-dimensional measurement and statistical analysis.Results When the operation guide plate was applied smoothly,the maximum error for maxilla was 1.2 mm (0.3-1.2 mm),and the maximum error for genioplasty was 1.7 mm,(0.5-1.7 mm),and the mean error was less than 1 mm.Follow-up for 12 months showed no adverse reaction.Conclusions Three dimensional printing surgical guide plate can accurately provide the osteotomy information,effectively control the jaw movement,and improve the orthognathic surgery accuracy of patients with partial jaw deformity.
ABSTRACT
Objective:To development a new method for sensitive detection of Porphyromanus gingivalis (P.gingivalis) based on magnetic encoding nanospheres and upconversion fluorescent encoding nanospheres.Methods:Magnetic and upconversion fluorescent encoding nanospheres were prepared by sol-gel method respectively,combined the monoclonal antibodies specific to P.gingivalis after modifying the surface of nanospheres.The system was used to detect P.gingivalis from mixed bacteria solution of P.gingivalis,F.nucleatum and S.mutans.Fluorescent microscopy with an external 980 nm near-infrared hght pulse laser,scanning and transmission microscope were used to evaluate the effectiveness of the detection system.Results:Magnetic and upconversion encoding nanospheres had better dispersion,particle size uniformity and homogeneous morphology.Besides,the magnetic encoding nanospheres had good magnetic properties and strong fluorescence intensity.P.gingivalis was captured by magnetic and upconversion encoding nanospheres in a mixed solution of the 3 bacteria with a detection limit of 10 CFU/ml.Conclusion:The method designed in this study can capture P.gingivalis sensitively in a mixed bacteria liquid.
