ObjectiveTo investigate the awareness of diabetic retinopathy (DR) prevention and treatment knowledge of diabetic patients in the community of Shenzhen, and analyze its influencing factors.MethodsA cluster random sampling method was used to select 904 patients with diabetes diagnosed in 6 community health service centers in 2 administrative districts of Shenzhen and included in this study. Questionnaire survey of patients were performed to understand their knowledge of DR prevention and treatment. The multi-factor logistic regression analysis method was used to analyze the related influencing factors of DR prevention knowledge awareness.ResultsAmong 904 patients, 144 patients (15.93%, 144/904) knew about DR prevention and treatment knowledge. The highest awareness rate were about "Diabetes can affect vision and even cause blindness" (88.60%, 801/904). The lowest awareness rate (6.20%, 56/904) were about "DR treatment methods". About "diabetes requires regular fundus examinations" and "diabetics", the awareness rate of fundus examination interval were less than 50.00%. The results of multivariate logistic regression analysis showed that gender [odds ratio (OR)=1.595], education level (OR=2.963, 3.937), monthly income level (OR=3.871, 4.675), diabetes course ≥15 years (OR=1.829), treatment measures (OR=3.318, 4.512). Whether people had DR (OR=1.605) were important factors that affected the awareness of DR prevention and treatment knowledge (P＜0.05).ConclusionsThe overall awareness of DR prevention and treatment knowledge among diabetic patients in the community of Shenzhen is relatively low. Males, low education and income levels are the main influencing factors.
ObjectiveTo explore the feasibil ity to repair defect on the neck and chest with the rectus abdominis flap which pedicle is lengthened by measuring the width, thickness, and the intercostal space of the inferior costicartilage using CT angiography (CTA). MethodsThirty cases receiving CTA and three-dimensional reconstruction between July and December 2013 were included in the study. Of 30 cases, 17 were male and 13 were female, aged 44-70 years (mean, 56 years). The width and thickness of the 3rd to 7th costicartilages and the distance of the 3rd to 6th intercostal spaces were measured, and the lengthened pedicle was calculated after the 4th to 7th costicartilage was cut off. Between July 2012 and November 2013, the lengthened pedicle of the rectus abdominis flap was cl inically used to repair the defect on the neck and chest in 4 cases. ResultsThe pedicle of the rectus abdominis flap was about 6 cm in length. When the left 7th, 6th, 5th, and 4th costicartilages were cut off, the average pedicle was lengthened by 4.07, 7.99, 12.50, and 17.48 cm respectively; when the right 7th, 6th, 5th, and 4th costicartilages were cut off, the average pedicle was lengthened by 4.63, 10.82, 16.64, and 22.05 cm respectively. In 4 flaps which were cl inically used to repair defects, 3 flap completely survived, 1 flap had partial necrosis. Three patients were followed up 6 months, and the appearance and texture of the flap were satisfactory; 1 patient failed to be followed up. ConclusionResecting the inferior costicartilage can prolong the pedicle of the rectus abdominis flap, therefore it can be used to repair defect on the upper chest and the neck.
The reporting quality of systematic reviews and meta-analyses is fundamental to the value of evidence in evidence-based medicine. As the internationally endorsed standard, the PRISMA statement and its extensive suite of extensions are crucial for standardizing reporting and enhancing transparency. However, a comprehensive, systematic understanding of its entire framework and profound challenges remains inadequate in the academic community. This review aims to systematically delineate and deeply analyze the complete PRISMA reporting guideline framework, evaluate its application value, uncover its implementation challenges, and forecast its future development directions. This paper traces PRISMA's evolution from its predecessor, QUOROM, to PRISMA 2020, highlighting key shifts in its core principles. It systematically constructs a multi-dimensional framework for the PRISMA family for the first time, categorizing its extensions by foundational versions, study design/analysis types, reporting process stages, disciplinary domains, and specific areas of focus, complemented by a forward-looking analysis of tools currently under development. The review delves into the deep-seated challenges in PRISMA's implementation, including misconceptions, inconsistent application, cross-disciplinary adaptability, and methodological limitations. It proposes that its future lies in balancing standardization with flexibility, enhancing globalized application, and deeply integrating with emerging technologies like artificial intelligence. The PRISMA framework has evolved from a mere reporting checklist into a core methodological architecture that promotes standardization throughout the entire evidence synthesis lifecycle. The continuous optimization and proper application of this framework are of critical theoretical and practical significance for enhancing the overall quality and impact of evidence synthesis research globally.
