Inflammatory Bowel Disease and Dementia:Evidence Triangulation from a Meta-Analysis of Observational Studies and Mendelian Randomization Study

Objective Observational studies have found associations between inflammatory bowel disease(IBD)and the risk of dementia,including Alzheimer’s dementia(AD)and vascular dementia(VD);however,these findings are inconsistent.It remains unclear whether these associations are causal.Methods We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia.Mendelian randomization(MR)analysis based on summary genome-wide association studies(GWASs)was performed.Genetic correlation and Bayesian colocalization analyses were used to provide robust genetic evidence.Results Ten observational studies involving 80,565,688 participants were included in this metaanalysis.IBD was significantly associated with dementia(risk ratio[RR]=1.36,95%CI=1.04-1.78;I2=84.8%)and VD(RR=2.60,95%CI=1.18-5.70;only one study),but not with AD(RR=2.00,95%CI=0.96-4.13;I^(2)=99.8%).MR analyses did not supported significant causal associations of IBD with dementia(dementia:odds ratio[OR]=1.01,95%CI=0.98-1.03;AD:OR=0.98,95%CI=0.95-1.01;VD:OR=1.02,95%CI=0.97-1.07).In addition,genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia.Conclusion Our study did not provide genetic evidence for a causal association between IBD and dementia risk.The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.

Influence of Climate and Socio-Economic Factors on the Spatio-Temporal Variability of Soil Organic Matter: A Case Study of Central Heilongjiang Province, China

For the scientific management of farmland, it is significant to understand the spatio-temporal variability of soil organic matter and to study the influences of related factors. Using geostatistical theory, GIS spatial analysis, trend analysis and a Geographically Weighted Regression （GWR） model, this study analyzed the response of soil organic matter to climate and socio-economic factors in central Heilongjiang Province during the past 25 years. Second soil survey data of China for 1979-1985, 2005 field sampling data, climate observations and socio-economic data for 1980-2005 were analyzed. First, soil organic matter in 2005 was spatially interpolated using the Co-Kriging method along with auxiliary data sets of soil type and pH. The spatio-temporal variability was then studied by comparison with the 1980s second soil census data. Next, the temporal trends in climate and socio-economic factors over the past 25 years were investigated. Finally, we examined the variation of the response of soil organic matter to climate and socio-economic factors using the GWR model spatially and temporally. The model showed that 53.82% area of the organic matter content remained constant and 29.39% has decreased during the past 25 years. The impact of precipitation on organic matter content is mainly negative, with increasing absolute values of the regression coefficient. The absolute value of regression coefficient of annual average temperature has decreased, and more areas are now under its negative effects. In addition, the areas of positive regression coefficient of annual sunshine hours have northward shifted, with the increasing absolute value of positive coefficient and decreasing absolute value of negative coefficient. The areas of positive regression coefficient of mechanized farming as a socio-economic factor have westward shifted, with the increasing absolute value of negative coefficient and decreasing absolute value of positive coefficient. The area of regions with the positive regression coefficient of irrigation has expanded. The regions with positive regression coefficient of fertilizer use have shrinked. The positive regression coefficient of mulch film consumption has significantly increased. The regression coefficient of pesticide consumption was mainly positive in the west of the study area, while it was negative to the east. Generally, GWR model is capable to investigate the influence of both climatic and socio-economic factors, avoided the insufficiency of other research based on the single perspective of climatic or socio-economic factors. Therefore, we can conclude that GWR model could provide methodological support for global change research and serve as basic reference for cultivated land quality improvement and agricultural decision making.

LAND USE CHANGE AND ITS SOCIO-ECONOMIC DRIVING FORCES UNDER STRESS OF PROJECT IN OLD RESERVOIR AREA——Case Study of Linshui Reservoir Area of Dahonghe Reservoir in Sichuan Province

The old reservoir areas built in 1950s- 1970s left behind many socio-economic problems, because of the administrative backward migration and little migration fund, and all these problems would be tied to land. Based on interviewing with peasant households, combining land use survey and socio-economic statistical index, this paper analyzed land use change and its corresponding driving forces in Linshui reservoir area of Dahonghe Reservoir. Results showed that land use change in the reservoir area was mainly embodied on low-lying land submergence and migration requisition land. The former changed the land use patterns, and the latter mainly reconstructed original land property and made land over-fragmented. Cultivated land per capita was 0.041ha in this area, below the cordon of cultivated land per capita enacted by FAO. Currently, there were still 30.25% of peasant households being short of grain in trimester of one year, and there were 35.27% of people living under the poverty line. The conditions of eco-environmerit in Linshui Reservoir Area were worse, and healthy and sub-healthy eco-environment accounted for less proportion, composed of green belt around the reservoir area and paddy field ecosystem, and economic forest and orchard ecosystem, respectively. The stress of the reservoir project was macroscopic background to analyze the driving factors of land use change, and real underlying diving factor of the land use change in the area was the change of cultural landscape under the stress of reservoir project. The rapid increase of population was the key factor to induce the change of man-land relationship in the reservoir area, the low level of rural economy was the crucial factor to decide how migrants input for production, and the belief of migrants, influencing the land use patterns in a certain extent, was the inducing factor to keep land use stable. The low-lying submergence and infrastructure construction accompanied the reservoir project were leading factors driving land use change in the area, while changes in land use patterns, after the reservoir being built, were the responses of peasant households＇ behaviors to land use change.

Socio-economic status and lifestyle factors are associated with achalasia risk: A population-based case-control study

AIM: To evaluate the association between various lifestyle factors and achalasia risk.METHODS: A population-based case-control study was conducted in Northern Ireland, including n = 151 achalasia cases and n = 117 age- and sexmatched controls. Lifestyle factors were assessed via a face-to-face structured interview. The association between achalasia and lifestyle factors was assessed by unconditional logistic regression, to produce odds ratios(OR) and 95% confidence interval(CI).RESULTS: Individuals who had low-class occupations were at the highest risk of achalasia(OR = 1.88, 95%CI: 1.02-3.45), inferring that high-class occupation holders have a reduced risk of achalasia. A history of foreign travel, a lifestyle factor linked to upper socioeconomic class, was also associated with a reduced risk of achalasia(OR = 0.59, 95%CI: 0.35-0.99). Smoking and alcohol consumption carried significantly reduced risks of achalasia, even after adjustment for socio-economic status. The presence of pets in the house was associated with a two-fold increased risk of achalasia(OR = 2.00, 95%CI: 1.17-3.42). Nochildhood household factors were associated with achalasia risk.CONCLUSION: Achalasia is a disease of inequality, and individuals from low socio-economic backgrounds are at highest risk. This does not appear to be due to corresponding alcohol and smoking behaviours. An observed positive association between pet ownership and achalasia risk suggests an interaction between endotoxin and viral infection exposure in achalasia aetiology.

Analysis of Coordination between the Public Service in Rural Areas and Socio-economic Development——A Case Study of Sichuan Province

Taking Sichuan Province as an example,by using the overall evaluation function of Sichuan's rural public service equalization development level and rural socio-economic development level,we conduct profound analysis on coordination between public service in Sichuan's rural areas and socio-economic development from 2003 to 2008.The results show that the coordination between rural public service and socio-economic development in Sichuan Province is not high,and the equalization phenomenon of rural public service construction and socio-economic development is very prominent.The equalization development of public service in rural areas of Sichuan Province from 2003 to 2008 lags behind socio-economic development.The coordination between public service equalization system in rural areas of Sichuan Province and socio-economic development system abates continuously;the coordination between infrastructure and socio-economic development increases slowly;the coordination between education and socio-economic development declines sharply;the coordination between public culture and socio-economic development tends to decrease;the coordination between ecological environment construction and socio-economic development decreases continuously with great amplitude;the coordination between public health and socio-economic development decreases continuously;the coordination between science and technology and socio-economic development lingers at low level;the coordination between social security and employment,and socio-economic development increases in fluctuation,but with small amplitude.

National Social Investment Programmes in Nigeria:A Descriptive Analysis of the Socio-Economic Contributions of N-Power Programme in Benue State

This study analysed the socio-economic contributions of N-Power programme amongst the beneficiaries of the scheme in Benue State.Prior to the introduction of N-Power programme,successive administrations in Nigeria have made concerted efforts towards improving the standard of living of the citizenry through the execution of various welfare or social intervention programmes,but not much successes were recorded.Learning from the mistakes of the past regimes,and by way of deliberate state policy,the Buhari’s government initiated a multi-pronged social investment policy,one of which is the N-power programme that came onboard in 2016,which also doubles as the subject of this study.To achieve the goal of this study,a combination of desktop research and survey design was employed.Questionnaires were administered to 390 respondents through a combination of stratified and random sampling techniques.The results of the survey were matched with that of the secondary data obtained through online websites and other related sources.The result indicated that N-Power made positive contributions to the socio-economic life of the beneficiaries in Benue State:specifically,the scheme contributed in poverty eradication,employment generation,skills acquisitions and capacity building.However,some aspect of our findings revealed that the programme has a number of challenges such as:inadequate cash support,delay in monthly cash transfer to beneficiaries,distance participants had to move to their work stations,absence of posting in N-Teach scheme,and lack of adequate working tools amongst others.To salvage this problem the paper recommended the following solutions:expansion of the scheme to cover N-Teach and other aspects,increment in the monthly cash transfer to cushion the high rate of inflation,support for the participants/beneficiaries in transportation and logistics,enrolment of more youth into the various schemes,proper monitoring and evaluation of the implementation of the schemes amongst others.

The domestic architecture of a traditional settlement is greatly influenced by the socio-economic and socio-cultural characteristics of its residents.Benin City which is the focus of the paper is a case of a traditional settlement undergoing domestic architectural evolution with the changing times influenced by factors of growth and development.The paper has examined the effect of socio-economic and socio-cultural characteristics as factors that partly determine the design,style,pattern,space use,organization,location and meaning as well as land use of the domestic architecture of Benin.The study employed the use of questionnaire administered to residents across the cross-section of the city.In the end,descriptive frequency tables were used to analyse the data collected from the residential zones in Benin.The research has been able to corroborate the theory that socio-economic and socio-cultural factors are some of the determinants/elements of domestic architecture of a people.

Exploring the Path of Shantytown Renewal Based on the Theory of Environment-behavior Studies: A Case Study of the Northwest Area of Saihantala in Baotou City

The application of environment-behavior studies plays an important role in studying the renewal of shantytowns.One of the most humane ways of renewal is designing and constructing the necessary urban spatial environment from the perspective of human daily behavior.Most of the shantytown renovation projects currently carried out in China are mainly focused on demolition and reconstruction,which not only incurs high costs but also damages the original social structure and economic model.During the process of shantytown renewal,it should improve the urban landscape,living environment,and life quality of residents,and ensure the daily life of shantytown residents without increasing their economic burden,and preserve the traces of urban development.In order to achieve this goal,it should explore the renewal strategies of shantytowns from the perspective of environment-behavior studies through behavior maps,on-site research,and literature review.Updating and design from a human perspective often achieve faster and better development;the renewal of shantytowns should be a bottom-up approach and start from a grassroots perspective,completing the renovation design through the composition of the population and behavioral patterns.

Telecommunications and Energy Infrastructure Sharing: Technical and Socio-Economic Impact Analysis in a Multi-Operator Environment in Burundi

The sharing of telecommunications infrastructure and power supply equipment is currently an applicable and very common model for grouping signal transmission and reception equipment and their power supply on the same site to ensure coverage of fixed, mobile, Internet and radio and television broadcasting networks. This study consists of producing an inventory of telecommunications and energy infrastructure sharing, focusing on the one hand on analyzing the impacts of active and passive sharing of telecommunications infrastructure from a technical point of view, particularly in terms of legal framework, deployment, coverage and exposure to electromagnetic radiation, and on the other hand on identifying the effects of infrastructure sharing from a socio-economic point of view in a multi-operator mobile telephony environment, by indicating the economic value of the revenue generated as a result of infrastructure sharing. Finally, the results will contribute to identify strategies for ensuring maximum deployment and coverage of the country, and for developing the information and communication technologies (ICT) sector in order to contribute to the digital transformation by digitising services using mobile telephony and the Internet in Burundi.

Research on the Interactive Impact of Transportation Systems on Socio-Economic Development

This paper aims to explore the interactive impact between transportation systems and socio-economic development,employing Structural Equation Modeling(SEM)to analyze data from 31 provincial-level administrative regions in China from 2013 to 2022.It comprehensively considers key indicators from the economic,social,and transportation sectors.The paper constructs a model encompassing 5 latent variables and 15 observed variables.Through in-depth analysis,it reveals the promoting role of transportation systems on economic growth and social development,as well as the demand for transportation system construction and optimization driven by socio-economic development levels.The results indicate that an efficient transportation system can not only directly drive economic growth but also indirectly promote social development by improving social welfare and enhancing quality of life.This paper provides new insights into understanding the complex relationship between transportation systems and socio-economic development and holds significant implications for policymakers in optimizing transportation infrastructure to foster economic and social development.

Association between socio-economic factors and the risk of overweight and obesity among Chinese adults:a retrospective cross-sectional study from the China Health and Nutrition Survey

Background:With the rising prevalence of obesity and overweight,increasing number of scholars paid attention to the negative effects on human health and life.Recent years,many studies have focused on the relation of socio-economic factors with the risk of overweight or obesity,but findings have been inconsistent.This study investigated the relationship between socio-economic factors and the risk of overweight and obesity among Chinese adults.Methods:This study was based on the survey of the China Health and Nutrition Survey in 2015,with 9245 Chinese adults aged 18-65 years old.Overweight and obesity were assessed by physical measurements of weight,height,and waist circumference.Multiple logistic models were used to estimate the odds ratios(ORs)and 95%confidence intervals(CIs)of the association.Results:Overall,the prevalence rates of general obesity and abdominal obesity were 15.5%and 22.6%,respectively.We found that education and per capita household income were positively associated with overweight and obesity risk in men.However,the association between education and obesity status was negative in women[general obesity:OR=0.64,95%CI(0.50-0.81);abdominal obesity:OR=0.62,95%CI(0.51-0.76)].Occupational status was only associated with general overweight in men.Conclusions:Results suggested that higher education and per capita household income were associated with an increased risk of overweight and obesity among Chinese men,whereas the associations were negative for women.We recommended that men with high levels of education and income,women with low levels of education,can engage in some physical activity,modify dietary,and adopt a new way of life to maintain their weight and general health.

Prevalence of Helicobacter pylori infection in Chinese military personnel:A cross-sectional,multicenter-based study

BACKGROUND Helicobacter pylori(H.pylori)infection is a prevalent disease encountered in military internal medicine and recognized as the main cause of dyspepsia,gastritis,and peptic ulcer,which are common diseases in military personnel.Current guidelines in China state all patients with evidence of active infection with H.pylori are offered treatment.However,the prevalence of H.pylori infection and its regional distribution in the military population remain unclear,which hinders effective prevention and treatment strategies.Understanding the prevalence of H.pylori infection in the military population will aid in the development of customized strategies to better manage this infectious disease.AIM To investigate the prevalence of H.pylori infection in the Chinese military population in different geographic areas.METHODS This multicenter,retrospective study included 22421 individuals from five tertiary hospitals located in north,east,southwest,and northwest cities of China.H.pylori infection was identified using the urea breath test,which had been performed between January 2020 and December 2021.RESULTS Of the 22421 military service members,7416(33.1%)were urea breath test-positive.The highest prevalence of H.pylori was in the 30-39 years age group for military personnel,with an infection rate of 34.9%.The majority of infected subjects were younger than 40-years-old,accounting for 70.4%of the infected population.The individuals serviced in Lanzhou and Chengdu showed a higher infection prevalence than those in Beijing,Nanjing,and Guangzhou,with prevalence rates of 44.3%,37.9%,29.0%,31.1%,and 32.3%,respectively.CONCLUSION H.pylori infection remains a common infectious disease among military personnel in China and has a relatively high prevalence rate in northwest China.

Climate Change Induced Land Degradation and Socio-Economic Deterioration: A Remote Sensing and GIS Based Case Study from Rajasthan, India

The present study attempts to identify and quantify climate change induced land degradation at watershed and village level in Jaggar Watershed of Eastern Rajasthan using remote sensing and GIS technique. The study utilizes Standard Geocoded FCC LISS II data of 1989, and LISS III data of 1998 and 2009 on 1:50,000 scale for Land use/land cover mapping. Maps were digitized, edited and analyzed in GIS to ascertain land use/land cover changes. Comparative analysis of the Land use/land cover statistics and village level household survey reveals that climate change has severely affected land use/land cover especially agriculture land. Agricultural land in the watershed has decreased from 12,026 ha (34%) to 10,400 ha (29.65%) from 1998 to 2009. The area occupied by surface water resources of the major water body has decreased by 207 ha owing to decline in rainfall over the years. Climate data analysis suggests that average maximum and minimum temperatures during the period 1977-2007 have increased by 1.2?C and 0.4?C respectively. Increasing trends of temperature suggests warming up of the area. Decline of ground water table by 1 - 2 m on annual basis coupled with significant drawdown has led to water scarcity in many parts of the watershed. The water table has gone down to a depth of 240 feet, which was reported at 60 - 70 feet 20 years back. The area has shown sharp decline of rainfall by 269 mm from 1977 to 2007. The survey results show that there has been shift in the cropping pattern during the last 20 years due to change in climate as well as decline in availability of water for irrigation. Climate change seems to have played a key role in Jaggar watershed resulting in land degradation and making rainfed agriculture more vulnerable.

Cohort study on the treatment of BRAF V600E mutant metastatic colorectal cancer with integrated Chinese and western medicine

BACKGROUND Patients with BRAF V600E mutant metastatic colorectal cancer(mCRC)have a low incidence rate,poor biological activity,suboptimal response to conventional treatments,and a poor prognosis.In the previous cohort study on mCRC conducted by our team,it was observed that integrated Chinese and Western medicine treatment could significantly prolong the overall survival(OS)of patients with colorectal cancer.Therefore,we further explored the survival benefits in the population with BRAF V600E mutant mCRC.AIM To evaluate the efficacy of integrated Chinese and Western medicine in the treatment of BRAF V600E mutant metastatic colorectal cancer.METHODS A cohort study was conducted on patients with BRAF V600E mutant metastatic colorectal cancer admitted to Xiyuan Hospital of China Academy of Chinese Medical Sciences and Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from January 2016 to December 2022.The patients were divided into two cohorts.RESULTS A total of 34 cases were included,with 23 in Chinese-Western medicine cohort(cohort A)and 11 in Western medicine cohort(cohort B).The median overall survival was 19.9 months in cohort A and 14.2 months in cohort B,with a statistically significant difference(P=0.038,hazard ratio=0.46).The 1-3-year survival rates were 95.65%(22/23),39.13%(9/23),and 26.09%(6/23)in cohort A,and 63.64%(7/11),18.18%(2/11),and 9.09%(1/11)in cohort B,respectively.Subgroup analysis showed statistically significant differences in median OS between the two cohorts in the right colon,liver metastasis,chemotherapy,and first-line treatment subgroups(P<0.05).CONCLUSION Integrated Chinese and Western medicine can prolong the survival and reduce the risk of death in patients with BRAF V600E mutant metastatic colorectal cancer,with more pronounced benefits observed in patients with right colon involvement,liver metastasis,combined chemotherapy,and first-line treatment.

Association between Non-high-density Lipoprotein Cholesterol to High-density Lipoprotein Cholesterol Ratio(NHHR)and Stroke among Adults in the USA:A Cross-Sectional NHANES Study

Objective The relationship between non-high-density lipoprotein(NHDL)cholesterol to high-density lipoprotein cholesterol(HDL-C)ratio(NHHR)and stoke remains unknown.This study aimed to evaluate the association between the adult NHHR and stroke occurrence in the United States of America(USA).Methods To clarify the relationship between the NHHR and stroke risk,this study used a multivariable logistic regression model and a restricted cubic spline(RCS)model to investigate the association between the NHHR and stroke,and data from the National Health and Nutrition Examination Survey(NHANES)from 2005 to 2018.Subgroup and sensitivity analyses were conducted to test the robustness of the results.Results This study included 29,928 adult participants,of which 1,165 participants had a history of stroke.Logistic regression analysis of variables demonstrated a positive association between NHHR and stroke(OR 1.24,95%CI:1.03-1.50,P=0.026).Compared with the lowest reference group of NHHR,participants in the second,third,and fourth quartile had a significantly increased risk of stroke after full adjustments(OR:1.35,95%CI:1.08-1.69)(OR:1.83,95%CI:1.42-2.36)(OR:2.04,95%CI:1.50-2.79).In the total population,a nonlinear dose-response relationship was observed between the NHHR and stroke risk(P non-linearity=0.002).This association remained significant in several subgroup analyses.Further investigation of the NHHR may enhance our understanding of stroke prevention and treatment.Conclusion Our findings suggest a positive correlation between the NHHR and an increased prevalence of stroke,potentially serving as a novel predictive factor for stroke.Timely intervention and management of the NHHR may effectively mitigate stroke occurrence.Prospective studies are required to validate this association and further explore the underlying biological mechanisms.

Perspectives of high-risk pregnant women on home care program in high-risk pregnancies: A multicenter, qualitative study

Objective:To explore the perspectives of high-risk pregnant women regarding the home care program for high-risk pregnancies.Methods:This qualitative study was conducted in a university hospital and 5 comprehensive health centers in Ahvaz,Iran,from February 2023 to July 2023.The sampling method used was purposive sampling considering the maximum possible diversity,which continued until data saturation.11 in-depth and semistructured interviews were conducted with high-risk pregnant women.Data were simultaneously analysed using Graneheim and Lundman content analysis by MAXQDA version 20 software.Results:Data analysis extracted 3 themes,12 categories,and 26 subcategories.The themes and categories were“high-risk pregnancy and related issues(pursuing treatment and paying attention to the high-risk situation by pregnant women,psychological aspect of high-risk pregnancy on pregnant women and caregivers,emotional and physical aspects of high-risk pregnancy,the consequences of high-risk pregnancy on the people around them and empowerment of high-risk pregnant women)”,“support dimension(family and community support for high-risk pregnant women)”,and“framework of program(acculturalization,means and equipment,security,manpower and the necessary arrangements for the home care)”.Conclusions:High-risk pregnancy affects various aspects of the lives of high-risk pregnant women and their families.Creating the necessary conditions for providing care at home plays a vital role in supporting high-risk pregnant women and removing related obstacles to receiving prenatal care in person.It will be especially beneficial for high-risk pregnant women in low-income areas.

Decreased desire to have children: A qualitative study

Objective:To explain barriers to childbearing among working women from the perspective of working women and midwives.Methods:In this study,a qualitative study of content analysis method was employed.The study was conducted from December 2021 to July 2022.The population consisted of working women and midwives.Data collection was conducted using semi-structured interviews and continued until data saturation was achieved.Through purposeful sampling,10 women and 11 midwives were selected as the sample.The data were analyzed by Graneheim and Lundman content analysis approach.For more rigorous,Nvivo 14 software was also used for data management,analysis,coding and organization of data.Results:This study included 21 women(10 women employees and 11 midwives)aged 25-43 years(for women employees)and 27-56 years(for midwives)with 1 to 34 years of job experience.In examination of participant’views about the barriers to childbearing,1124 codes were identified,of which we managed to extract six subthemes and two themes.Two themes emerged:“lack of social support and lack of family support”.Subthemes of“lack of social support”were“inadequate leave,long distance from workplace,and insufficient wages”.Subthemes of“lack of family support”were“lack of spouse support,lack of spouse's family support,and lack of their family support”.Conclusions:Different socioeconomic factors influence childbearing tendency in working women.Social and family supports play an important role in this regard.It is important to take these factors into account at the time of policymaking in the field of midwifery.

Association between Fish Consumption and Stroke Incidence Across Different Predicted Risk Populations:A Prospective Cohort Study from China

Objective The relationship between fish consumption and stroke is inconsistent,and it is uncertain whether this association varies across predicted stroke risks.Methods A cohort study comprising 95,800 participants from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project was conducted.A standardized questionnaire was used to collect data on fish consumption.Participants were stratified into low-and moderate-to-high-risk categories based on their 10-year stroke risk prediction scores.Hazard ratios(HRs)and 95%confidence intervals(CIs)were estimated using Cox proportional hazard models and additive interaction by relative excess risk due to interaction(RERI),attributable proportion(AP),and synergy index(SI).Results During 703,869 person-years of follow-up,2,773 incident stroke events were identified.Higher fish consumption was associated with a lower risk of stroke,particularly among moderate-to-high-risk individuals(HR=0.53,95%CI:0.47-0.60)than among low-risk individuals(HR=0.64,95%CI:0.49-0.85).A significant additive interaction between fish consumption and predicted stroke risk was observed(RERI=4.08,95%CI:2.80-5.36;SI=1.64,95%CI:1.42-1.89;AP=0.36,95%CI:0.28-0.43).Conclusion Higher fish consumption was associated with a lower risk of stroke,and this beneficial association was more pronounced in individuals with moderate-to-high stroke risk.

Outcomes of bile duct cannulation using a novel contrast-enhanced catheter: A single-center, retrospective cohort study

BACKGROUND Endoscopic retrograde cholangiopancreatography is a challenging procedure involving bile duct cannulation.Despite the development of several cannulation devices,none have effectively facilitated the procedure.AIM To evaluate the efficacy of a recently developed catheter for bile duct cannulation.METHODS We retrospectively examined 342 patients who underwent initial cholangiopan-creatography.We compared the success rate of bile duct cannulation and the incidence of complications between the groups using existing and novel catheters.RESULTS The overall success rates of bile duct cannulation were 98.3%and 99.1%in the existing and novel catheter groups,respectively(P=0.47).The bile duct cannulation rate using the standard technique was 73.0%and 82.1%in the existing and novel catheter groups,respectively(P=0.042).Furthermore,when catheterization was performed by expert physicians,the bile duct cannulation rate was significantly higher in the novel catheter group(81.3%)than in the existing catheter group(65.2%)(P=0.017).The incidence of difficult cannulation was also significantly lower in the novel catheter group(17.4%)than in the existing catheter group(33.0%)(P=0.019).CONCLUSION The novel catheter improved the bile duct cannulation rate using the standard technique and reduced the frequency of difficult cannulation cases,valuable tool in endoscopic retrograde cholangiopancreatography procedures performed by experts.

Bibliometric analysis on the top one hundred cited studies on gastrointestinal endoscopy

BACKGROUND Gastrointestinal endoscopy has been widely used in the diagnosis and treatment of gastrointestinal diseases.A great many of studies on gastrointestinal endoscopy have been done.AIM To analyze the characteristics of top 100 cited articles on gastrointestinal endoscopy.METHODS A bibliometric analysis was conducted.The publications and their features were extracted from the Web of Science Core Collection,Science Citation Index-Expanded database.Excel,Web of Science database and SPSS software were used to perform the statistical description and analysis.VOSviewer software and Map-Chart were responsible for the visualizations.RESULTS The top 100 cited articles were published between 1976 and 2022.The guidelines(52%)and clinical trials(37%)are the main article types,and average publication year of the guidelines is much later than that of the clinical trials(2015 vs 1998).Among the clinical trials,diagnostic study(27.0%),cohort study(21.6%),case series(13.5%)and cross-sectional study(10.8%)account for a large proportion.Average citations of different study types and designs of the enrolled studies are of no significant differences.Most of the 100 articles were published by European authors and recorded by the endoscopic journals(65%).Top journals in medicine,such as the Lancet,New England Journal of Medicine and JAMA,also reported studies in this field.The hot spots of involved diseases include neoplasm or cancer-related diseases,inflammatory diseases,obstructive diseases,gastrointestinal hemorrhage and ulcer.Endoscopic surgery,endoscopic therapy and stent placement are frequently studied.CONCLUSION Our research contributes to delineating the field and identifying the characteristics of the most highly cited articles.It is noteworthy that there is a significantly smaller number of clinical trials included compared to guidelines,indicating potential areas for future high-quality clinical trials.
