Objective To analyze the trend of standardized infection ratio (SIR) of surgical site infection (SSI) in small bowel surgery, objectively evaluate the effect of infection control, and provide evidence-based strategies for SSI prevention. Methods According to Centers for Disease Control and Prevention (CDC) / National Healthcare Safety Network (NHSN) surveillance definitions for specific types of infections and the monitoring methods of SSI events published by NHSN, the SSI and related risk factors of adult inpatients undergoing small bowel surgery in Yichang Central People’s Hospital between January 1, 2016 and December 31, 2022 were prospectively monitored. The inpatients undergoing small bowel surgery that meets the definition of International Classification of Diseases, 10th Revision Clinical Modifications/Procedure Coding System (ICD-10-CM/PCS), a multivariate binary logistic regression model was used to calculate the predicted infections in each year, the model included the risk factors for small bowel surgery in NHSN Complex Admission/Readmission (A/R) SSI Model with 7 years of surveillance data as the baseline. The SIR was calculated by dividing the number of observed SSI by the number of predicted SSI in each year. The Mid-P method was used to test the difference of SIR compared to the previous year, and the linear regression model was used to analyze the trend of SIR. Results A total of 2 436 patients were included, with 48 cases of deep incision infection and 49 cases of organ/cavity infection, and the overall incidence rate of infection was 4.0%. From 2016 to 2022, there were 151, 244, 222, 260, 320, 408, and 831 patients who underwent small bowel surgery, respectively. The Mid-P test showed that there was a significant difference in SIR from 2016 to 2019 (P<0.05), and there was an increase in 2018 compared with 2017. There was no significant difference in SIR compared to the previous year from 2019 to 2022 (P>0.05), and there was no significant difference in the trend of SIR of SSI (P=0.065). Conclusions From January 1, 2017, to December 31, 2022, advances have been made in SSI control practices of small bowel surgery in six consecutive years, except for 2018, but there was no annual downward trend from 2020 to 2022. The use of SIR provides a new approach for evaluating the quality of infection control.
ObjectiveTo understand the current status, research hotspots, and future trends in the field of retinoblastoma (RB). MethodsUsing the Web of Science Core Collection SSCI and SCI-Expanded as data sources, relevant RB literature from January 2015 to November 2024 was retrieved. The bibliometric analysis software CiteSpace 6.2.R6 was employed to perform visual analyses of countries/regions, institutions, journals, authors, co-cited references, and keywords. ResultsA total of 5 042 relevant publications were identified. Annual publication numbers in this field consistently exceeded 400, peaking at 565 in 2021. The United States contributed the highest number of publications, with 1 600 articles (31.73%). Among institutions, Harvard University ranked first with 167 publications (3.31%). Abramson DH of Memorial Sloan Kettering Cancer Center published the most papers (75). Nature (United Kingdom) received the highest citation count (2 349). The highest betweenness centrality was observed for the United States (0.14) among countries/regions, Shanghai Jiao Tong University (0.21) among institutions, and Berry JL of Children’s Hospital Los Angeles (0.21) at the author level. Co-citation and keyword analyses revealed that RB research hotspots are shifting from a focus on basic molecular mechanisms, such as the cell cycle and RB protein, toward advanced therapeutic strategies, such as intra-arterial chemotherapy and nanoparticle-based drug delivery. Emerging keywords such as complexity, chemoresistance and carboplatin indicate that future studies will focus on optimising diagnosis and treatment. ConclusionsFrom 2015 to 2024, RB research displayed a sustained growth trend, with the United States and its institutions and scholars contributing the most publications. The research focus has shifted from the exploration of molecular mechanisms to the optimization of precise treatment strategies, among which the application of nanotechnology and the resolution of drug resistance mechanisms will become key breakthrough directions.
Objective To explore the global research status and trends of continuous renal replacement therapy (CRRT) based on knowledge visualization analysis. Methods Based on the Web of Science Core Collection, studies reporting CRRT research that were published between June 2014 and June 2023 were retrieved and collected after manual review. VOSviewer and CiteSpace softwares were used for bibliometric visualization analysis, including publication trends, geographical distribution characteristics, journal distribution characteristics, author contributions, citations, funding source characteristics, and keyword clustering. Results A total of 2708 papers were analyzed, with an increasing trend in the number of articles and citation frequency from 2015 to 2021. The United States was the most prolific country and France was the most influential country. The University of Pittsburgh in the United States had the highest number of publications among research institutions and showed higher motivation for inter-institutional collaboration. The University of Queensland in the Australia had the highest average citation frequency. Professor Rinaldo Bellomo of Australia was the most productive author and Professor Jeffrey Lipman was the most influential. Jason A. Roberts, Jeffrey Lipman and Claudio Ronco were the three authors who had the highest number of collaborations with other authors. Keyword cluster analysis showed that the prognosis of CRRT for renal disease was the focus of research, with hotspots of research being antibiotics, citrate accumulation, plasma replacement, lactate clearance, acute respiratory distress syndrome, and coronavirus disease 2019. Coupling analysis of the literature showed that exploring the indications for CRRT and optimizing treatment prescription were at the forefront of research. Conclusions The present study of CRRT has generally shown an upward trend in the last decade. The management and efficacy of CRRT remains a hot topic of research. Exploring the indications for CRRT and optimizing treatment prescriptions may be a popular research direction and trend in the future.
Optical imaging technology of ocular fundus, including fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and fundus autofluorescence (FAF), is growing at an unprecedented speed and scale and is integrating into the routine clinical management of ocular fundus diseases, such as diagnosis, treatment, and mechanism study. While FFA allow us to observe the retinal and choroidal blood circulation, OCT and FAF are non-invasive, fast and quantifiable measurement; such techniques show even more unique advantages and are favored tools. All these retinal imaging technologies, together with a variety of retinal function assessments, bring us into the era of big data of ocular fundus diseases. All of these developments are the challenges and opportunities for the operator and user of these fundus optics imaging technologies. In order to improve its clinical applications and allocate resources rationally, we need to understand the optical properties of these retinal imaging technologies, and standardize diagnosis behavior. This is a continuous learning process needs to continue to explore.
Using optical imaging equipment with different wavelength and computer technology, fundus optical imaging diagnostic techniques can record fundus reflected light, auto fluorescence and emitted light after excitation by external light source in order to observe and analyze the structure and pathological process of retina and choroid. Advances in fundus optical image capture technology (including laser, confocal laser, spontaneous auto-fluorescence, multispectral imaging) and storage and analysis technology, promote this field into a high-definition digital imaging era, with features of rapid, non-invasive, wide-angle three-dimensional multi-level integration, dynamic automatic navigation location tracking and combined application of a variety of optical imaging diagnostic techniques. In order to promote clinical and scientific research of ocular fundus diseases, we need to understand the development trend of optical imaging diagnostic technique, interpret the fundus imaging features appropriately, reasonably chose different inspection techniques, establish standardized diagnosis criteria and continue to expand clinical applications.
ObjectiveTo analyze the research hotspots and development trends of core outcome set (COS) from 2015 to 2024, providing a reference for future research in this field. MethodsWe retrieved literature on COS research from the Web of Science Core Collection and CNKI spanning January 1, 2015 to December 31, 2024. We extracted and organized data on the number of publications, journals, citation frequency, and keywords using Excel 2021. We performed keyword clustering analysis using VOSviewer 1.6.13 and generated strategic coordinate maps using Bibliometrix 3.13 in R 4.3.1. ResultsWe included a total of 1 288 studies, comprising 1 085 English publications and 203 Chinese publications. From 2015 to 2024, the number of COS publications showed a steady increase. English journals covered a wide range of fields, while Chinese journals were mainly focused on traditional Chinese medicine. High-impact articles primarily focused on COS methodology. Chinese literature mainly concentrated on the application of COS in traditional Chinese medicine, while English literature focused on child health, Delphi surveys, quality of life, and pain. The results of the strategic coordinate map showed that research on acupuncture core outcome indicators, qualitative studies of surgical COS, and Delphi-based COS for quality of life in patients with rheumatoid diseases were relatively weak, with significant room for improvement. ConclusionOver the past decade, COS research has shown a steady growth trend and has gradually become an important tool for improving the standardization and scientific rigor of clinical research. As COS research continues to expand, there is increasing overlap in the scope and findings of different studies. Future research could incorporate umbrella and basket study designs to optimize resource utilization and promote the application of COS in clinical practice.
In 2025, the American Cancer Society published "Cancer statistics, 2025", which projected cancer data for the upcoming year based on incidence data collected by central cancer registries (through 2021) and mortality data obtained from the National Center for Health Statistics (through 2022). Similarly, the National Cancer Center of China released "Cancer incidence and mortality in China, 2022" in December 2024, analyzing data from 22 cancer registries across the country. This study provides a comparative analysis of cancer incidence and mortality trends in China and the United States during the same period, with a focus on sex- and age-specific distributions and long-term changes in cancer patterns. Long-term trends indicate that lung and liver cancer mortality rates in China have declined, primarily due to tobacco control measures and hepatitis B vaccination programs. However, the burden of gastric and esophageal cancers remains substantial. In the United States, mortality rates for colorectal and lung cancers have continued to decline, largely attributed to widespread screening programs and advances in immunotherapy. As economic growth and social development, China’s cancer profile is gradually shifting towards patterns observed in countries with high human development index. However, the prevention and control of upper gastrointestinal cancers remains a critical public health challenge that requires further attention.
The hallmark of the recent latest advances in diagnostic fundus imaging technology is combination of complex hierarchical levels and depths, as well as wide-angle imaging, ultra-wide imaging. The clinical application of wide-angle and ultra-wide imaging, not only can reevaluate the role of the peripheral retina, the classification types and treatment modalities of central retinal vein occlusion, and enhance the reliability of diabetic retinopathy screening, improve the classification and therapeutic decision of diabetic retinopathy, and but also can help guide and improve laser photocoagulation. However we must clearly recognize that the dominant role of ophthalmologists in the diagnosis of ocular fundus diseases cannot be replaced by any advanced fundus imaging technology including wide-angle imaging. We emphasize to use the three factors of cognitive performance (technology, knowledge and thinking) to improve the diagnosis of ocular fundus diseases in China.
ObjectiveTo analyze the gender-specific distribution patterns of the disease burden of tracheal, bronchial, and lung cancer (hereinafter referred to as lung cancer) attributed to tobacco from 1990 to 2021 globally and in China and the United States (US), and to predict the trend of disease burden changes from 2022 to 2031, aiming to provide multi-dimensional evidence-based support for optimizing tobacco control strategies and precise lung cancer prevention and control systems. MethodsData on the disease burden of lung cancer attributed to tobacco from 1990 to 2021 globally and in China and the US were extracted and integrated from the Global Burden of Disease (GBD) 2021 database. The Joinpoint 4.9.1.0 software was used to analyze the corresponding trends in disease burden. The Bayesian age-period-cohort (BAPC) prediction model was employed to forecast the disease burden of lung cancer from 2022 to 2031. ResultsIn 2021, China had the highest number of deaths and disability-adjusted life years (DALYs) due to lung cancer attributed to tobacco, followed by the US. The top three risk factors for lung cancer globally and in China and the US from 1990 to 2021 were tobacco, air pollution, and occupational risks. The disease burden of lung cancer patients attributed to tobacco has been decreasing year by year in the global and US populations [the average annual percentage change (AAPC) values of age-standardized mortality rate and DALYs rate were: globally: −0.96%, −1.28%; US: −2.33%, −2.72%], while it has been increasing in China (the AAPC values of age-standardized mortality rate and DALYs rate were 0.28% and −0.02%, respectively). From a gender perspective, the disease burden of male patients with lung cancer attributed to tobacco was much higher than that of female patients from 1990 to 2021. Compared to the global average, the disease burden of lung cancer attributed to tobacco in China and the US from 1990 to 2021 was still heavy, with China’s burden being higher than that of the US. The elderly population aged ≥65 years in the global context and in China and the US was the primary group affected by the disease burden of lung cancer attributed to tobacco. The BAPC prediction model indicated that from 2022 to 2031, the age-standardized rates of lung cancer attributed to tobacco in the global context and in China and the US would show a declining trend. ConclusionFrom 1990 to 2021, the disease burden of lung cancer attributed to tobacco in China and the US was still heavy compared to the global average, with China’s burden being significantly higher than that of the US. The focus on prevention and control for both countries remains among the middle-aged and elderly population (especially males), which is a key challenge for tobacco-related lung cancer prevention and treatment work in the next 10 years.
ObjectiveTo systematically analyze the spatiotemporal distribution characteristics and epidemiological trends of tracheal, bronchus, and lung cancer (TBL) disease burden attributed to air pollution globally and in China and the United States from 1990 to 2021. Furthermore, based on predictive models, assess the patterns of disease burden changes from 2022 to 2031, providing a scientific basis for formulating targeted TBL prevention and control strategies. MethodsBased on the Global Burden of Disease (GBD) 2021 database, we analyzed the disease burden data of TBL attributed to air pollution globally and in China and the United States from 1990 to 2021. R Studio 4.3.2 software was used to analyze the corresponding trends and the Bayesian age-period-cohort (BAPC) prediction model was used to predict the status of the disease burden of TBL attributed to air pollution in the world and in China and the United States from 2022 to 2031. ResultsIn 2021, the highest number of deaths and disability-adjusted life years attributed to air pollution were in China (211 400 patients and 4.8947 million person-years), followed by the United States (6 000 patients and 124 300 person-years). The age standardized mortality rate (ASMR) and age standardized disability-adjusted life years rate (ASDR) of TBL due to air pollution in the world and in China and the United States showed a decreasing trend (with an average annual percentage change of<0). From 1990 to 2021, the ASMR and ASDR of TBL in China due to air pollution were much higher than those in the United States and the global average. In terms of gender, from 1990 to 2021, the disease burden of male patients with TBL attributed to air pollution in the world and in China and the United States was much higher than that of female patients. The BAPC prediction model showed that from 2022 to 2031, the ASMR and ASDR of TBL attributed to air pollution will showed an upward trend globally, while they showed a downward trend in China and the United States. ConclusionOver the past 30 years, the air pollution-related TBL disease burden in the world and in China and the United States has continued to decline, but China's level is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the elderly population aged ≥50 years being high-risk groups. In the future, the global disease trend may reverse and rise, while China and the United States are expected to continuously decline. However, precise prevention and control for high-risk groups remains a key challenge.
