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.
Objective To summary the incidence rate and trends of cancers in China. MethodsBy compiling and analyzing the Chinese Cancer Registry Annual Report from 2008 to 2021, we summarized the regional and population distribution characteristics of overall and high-incidence rate cancers in China and analyzed influencing factors. ResultsFrom 2005 to 2018, the overall crude incidence of cancers in China showed a continuous upward trend. The incidence rate in the eastern region (incidence rate was 353.26/100 000 in 2018, the following data were crude incidence rate in 2018) was significantly higher than those in the central (269.47/100 000) and western regions (253.71/100 000), while the incidence rates in the central and western regions were closer. 2005–2018, the incidence rates of male was higher than that of female, and the population aged 80 years old or older (2 741.02/100 000) had the highest incidence rate of cancers, and the incidence rate of people aged 0–14 years old (41.38/100 000) was the lowest. From 2005–2018 (except for 2009), lung cancer (65.05/100 000), gastric cancer (27.03/100 000), liver cancer (27.42/100 000), colorectal cancer (30.51/100 000), and breast cancer (43.02/100 000) were the top 5 highest incidence rates of China’s cancers, of which lung cancer ranked the first in different regions, and the ranking of other cancers varied in different regions. The top 5 cancers in males’ incidence rates from 2005 to 2018 were lung cancer (83.45/100 000), gastric cancer (37.12/100 000), liver cancer (40.02/100 000), colorectal cancer (35.32/100 000) and esophageal cancer (26.30/100 000); the top 5 cancers in females’incidence rates had changed a lot in different years, breast cancer, lung cancer, colorectal cancer, gastric cancer, liver cancer, thyroid cancer and cervical cancer had all been in the top 5, for example, in 2018, the top 5 cancers in female were lung cancer (46.10/100 000), breast cancer (43.02/100 000), colorectal cancer (25.56/100 000), thyroid cancer (24.60/100 000) and cervical cancer (18.10/100 000).ConclusionsThe crude incidence rate of cancers in China continues to rise, with the cancer spectrum showing new characteristics that combine high-incidence rate cancers in developed countries (e.g., breast cancer, colorectal cancer) with common cancers in developing countries (e.g., gastric cancer, liver cancer). The situation of cancer prevention and control remains challenging.
Sleep apnea syndrome (SAS) is a kind of harmful systemic sleep disorder with high incidence, and the pathological mechanism of it is complicated and the diagnosis and treatment are difficult. Mining the characteristic information of SAS from the single or small physiological signal is a hot topic in the research of sleep disorders in recent years. In our study shown in this paper, the detrended fluctuation analysis (DFA) was used to analyze sleep electroencephalogram (EEG) of SAS patients and normal healthy persons based on the non-stationary and nonlinear characteristics. It was found that in both groups, the scaling exponents increased gradually with the deepening of sleep, and in the rapid eye movement (REM) stage, the scaling exponents decreased. The scaling exponents of SAS group were significantly higher than those of the healthy group. The performance of SAS diagnosis based on scaling exponents was evaluated with receiver operator characteristic (ROC) curve. The optimal threshold value 0.81 for the SAS and normal control were obtained, corresponding to the sensitivity 94.4%, specificity 99.2%, and area under curve (AUC) was 0.994. The results show that DFA scaling exponents have a good discrimination power and accuracy for the SAS, which provide a new theoretical basis for SAS diagnosis.
ObjectiveTo analyze the disease burden and evolving trends for gastric cancer in China and worldwide from 1990 to 2021. MethodsBased on the 2021 Global Burden of Disease (GBD) database, we analyzed the burden of gastric cancer using indicators such as incidence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lost due to disability (YLDs). Joinpoint regression analysis was used to calculate the average annual percentage change (AAPC) of these indicators to show trends over time. ResultsIn 2021, the standardized incidence rate of gastric cancer was 14.33 (per 100 000) worldwide and 29.05 (per 100 000) in China, with corresponding standardized mortality rates of 11.20 (per 100 000) and 21.51 (per 100 000). The standardized incidence rate of gastric cancer in China trended downward during 1990–2021 (AAPC=–1.61%, P<0.05), but was lower than the global decline (AAPC=–1.77%, P<0.05). During 1990-2021 in China, the rates of standardized DALYs (AAPC=–2.76%, P<0.05), standardized YLLs (AAPC=–2.78%, P<0.05) and standardized YLDs (AAPC= –1.25%, P<0.05) all showed a significant decrease. The global rates of standardized DALYs (AAPC=–2.42%, P<0.05), standardized YLLs (AAPC=–2.44%, P<0.05) and standardized YLDs (AAPC=–1.56%, P<0.05) all showed a significant decrease. These AAPC values above indicated a general attenuation in the gastric cancer burden across all age groups, both in China and worldwide. ConclusionsDespite these signs of a decline in disease burden indicators for gastric cancer in China and worldwide, the number of cases and deaths in gastric cancer remains substantial coupled with the heavy burden on the healthcare system. Therefore, increased efforts in early detection and prevention strategies are of utmost importance to further reduce the impact of this malignant disease.
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 analyze and compare the incidence, mortality, temporal trends, and cancer spectrum differences between China and the United States (US), providing theoretical support for cancer prevention and control in China. MethodsAge standardized incidence rate (ASIR), age standardized mortality rate (ASMR), and cancer site composition were extracted from GLOBOCAN, Cancer Statistics 2025, the China Cancer Registry Annual Report, and other epidemiological sources. Spatial (urban-rural, sex specific) and temporal distributions were described, and average annual growth rate (AAGR) were calculated. ResultsFrom 2005 onward, China exhibited a modest rise in ASIR, whereas the US showed a decline (AAGR: 0.58 vs –0.42); nevertheless, China’s overall incidence remained lower (2022 ASIR = 201.61/100 000) than that of the US (303.60/100 000). Both countries experienced decreasing ASMR (AAGR: –1.03 vs –1.72). In both nations, male ASIR and ASMR were higher than female. Since 2005, the top three US cancers had remained prostate (men) or breast (women), lung and colorectal cancer. In China, incidences of lung, colorectal, female breast and thyroid cancers had continued to rise, while stomach and liver cancer incidences had declined yet still rank high among men. Urban ASIR in China exceeded rural rates, whereas rural ASMR was higher than urban counterparts. ConclusionsAccelerating population ageing and lifestyle transitions have driven an upward incidence trend in China, accompanied by a shift towards a mixed pattern of traditional and emerging cancer risks. Drawing on US experience, China should intensify tobacco control measures, expand organized screening and early detection programs, implement comprehensive interventions for priority cancers, strengthen primary level capacity and improve treatment access in rural areas, thereby establishing a more effective national cancer prevention and control system.
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.
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, and to assess the patterns of disease burden changes from 2022 to 2031 based on predictive models, 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, China had the highest number of deaths and disability-adjusted life years attributed to air pollution (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. 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 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 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 disease burden is still significantly higher than the global average. The disease burden in men far exceeds that in women, with men and the 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.
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.
