Methods A total of 600 children from childcare institutions within the study area from March 2022 to March 2024 were randomly divided into a control group (n=300) and an observation group (n=300) using random sampling. The control group received only routine health education, while the observation group additionally received standardized prevention measures (standardized environmental disinfection, active case surveillance, and household prevention guidance). The implementation scores of household prevention measures and HFMD incidence rates were compared between the two groups after six months of intervention. Results Prior to intervention, there was no significant difference in household prevention scores between the two groups (control group: 4.12±1.03 vs. observation group: 4.09±1.15, P>0.05). After intervention, the observation group's score improved to 8.76±0.89, significantly higher than the control group's 5.23±1.07, while its HFMD incidence rate of 3.33% (10/300) was markedly lower than the control group's 11.67% (35/300);both differences were statistically significant (P<0.05). Conclusion Standardized prevention interventions effectively enhance household compliance with prevention measures and significantly reduce HFMD incidence, demonstrating substantial public health value and suitability for widespread implementation in childcare settings and other child-intensive environments.展开更多

摘要Acute exposure to high altitude can cause acute altitude illnesses and is associated with impaired cognitive and physical performance.The most effective preventive strategies currently recommended include environmental acclimatization(slow ascent and/or pre-acclimatization)or pharmacological support of acclimatization using acetazolamide.However,these strategies are not practical for high-altitude exposures that require rapid and unplanned ascent,high physical and mental performance,such as rescue missions or military operations.Dexamethasone and other modulators of the glucocorticoid system take effect quickly and are effective alternatives for preventing acute altitude illnesses when rapidly ascending to high altitudes.As the efficacy of dexamethasone in preventing acute mountain illnesses remains controversial,a review of existing studies on the use of dexamethasone for the prevention of acute mountain sickness was conducted,aiming to determine the best strategy.Possible mechanisms of protection against acute altitude illnesses are discussed based on the results of clinical trials.The data indicate that dexamethasone is most effective at altitudes above 4000 m at doses of 8–16 mg/d.Appropriately designed and powered trials are needed to obtain more evidence-based results on the dosage and timing of dexamethasone administration,and to provide optimized recommendations for the application of this powerful pharmacological tool.

摘要To uncover the decision-making mechanisms and evolutionary dynamics of multiple stakeholders in highway noise pollution control,a three-party evolutionary game model involving the government,operators,and the public is constructed.The operation period is divided into different stages for differentiated analysis.A simulation analysis was performed on the Lituo sinking section of the Beijing-Hong Kong-Macao Highway to assess the impact of variations in critical elements on the system.The results indicate that the Lituo sinking section of the Beijing-Hong Kong-Macao Highway is currently in its early stage of development,with the corresponding strategies being active regulation,excessive emissions,and supervision.When the cost of the government’s active regulation decreases from 1×105 to 5×104 yuan,the system converges more rapidly toward the active regulation strategy.When the cost of the operator’s excessive emissions increases from 14.08×106 to 20.00×106 yuan,the system drives the operator toward the standardized emission strategy.In addition,when the cost of public supervision decreases from 15×104 to 5×104 yuan and the compensation paid by operators to the public increases from 1.288×106 to 2.576×106 yuan,the system converges more quickly toward the supervision strategy.The cost of the operator’s excessive emissions serves as the core decision variable for achieving the ideal equilibrium in the three-party game involving government active regulation,operator standardized emissions,and public supervision.
摘要Upper gastrointestinal(UGI)cancers remain a major global health burden,particularly in high-incidence regions.Traditionally,endoscopic screening has been positioned as a secondary prevention strategy aimed at detecting premalignant lesions and early-stage cancers.However,emerging evidence suggests that the role of endoscopic screening may extend beyond early diagnosis and into the realm of primary cancer prevention.Recent prospective data suggest that participation in UGI endoscopic screening programs may be associated with reductions in modifiable behavioral risk factors,including cigarette smoking,alcohol consumption,and unhealthy dietary habits.These findings challenge the conventional paradigm that screening solely identifies disease and instead support the concept that screening encounters may serve as critical behavioral intervention windows(i.e.,brief,clinician-delivered risk communication and counseling opportunities during and after screening).From an oncologic perspective,this raises important questions regarding how screening programs can be optimized to function as structured risk-modification platforms.This review examines the evolving concept of endoscopy as a catalyst for primary prevention,integrating behavioral science,risk stratification models,and population-based cancer control strategies.We discuss how screening-triggered health education,individualized risk communication,and integration with molecular and epidemiologic risk profiling could transform UGI cancer prevention frameworks.Furthermore,we explore the implications of redefining screening programs as multidimensional interventions rather than purely diagnostic tools.As precision oncology advances,cancer prevention must evolve accordingly.Reframing UGI endoscopic screening from a detection-centered approach to a precision prevention platform may conceptually enhance long-term cancer control,reduce population-level risk exposure,and improve cost-effectiveness in high-risk regions.Future implementation research is warranted to validate sustainable models that integrate behavioral modification into structured screening pathways.

摘要Objective To evaluate the practical efficacy of standardized prevention and control interventions implemented by disease control centers in preventing pediatric hand, foot, and mouth disease (HFMD), clarify their role in reducing incidence rates and enhancing household prevention capabilities, and provide reliable references for public health interventions. Methods A total of 600 children from childcare institutions within the study area from March 2022 to March 2024 were randomly divided into a control group (n=300) and an observation group (n=300) using random sampling. The control group received only routine health education, while the observation group additionally received standardized prevention measures (standardized environmental disinfection, active case surveillance, and household prevention guidance). The implementation scores of household prevention measures and HFMD incidence rates were compared between the two groups after six months of intervention. Results Prior to intervention, there was no significant difference in household prevention scores between the two groups (control group: 4.12±1.03 vs. observation group: 4.09±1.15, P>0.05). After intervention, the observation group's score improved to 8.76±0.89, significantly higher than the control group's 5.23±1.07, while its HFMD incidence rate of 3.33% (10/300) was markedly lower than the control group's 11.67% (35/300);both differences were statistically significant (P<0.05). Conclusion Standardized prevention interventions effectively enhance household compliance with prevention measures and significantly reduce HFMD incidence, demonstrating substantial public health value and suitability for widespread implementation in childcare settings and other child-intensive environments.
摘要BACKGROUND Post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is a prevalent and potentially serious complication in patients undergoing endoscopic retrograde cholangiopancreatography.AIM To comprehensively assess the efficacy of indomethacin therapy in reducing PEP risk.METHODS We searched PubMed,EMBASE,Scopus,and Cochrane Library databases to identify randomized controlled trials(RCTs)that compared rectal indomethacin with a control group to prevent PEP.Duplicates were removed,and studies were included based on the established inclusion criteria.We used the Cochrane Collaboration’s tool to assess the risk of bias in the RCTs.A random-effects model was applied to produce pooled risk ratios(RRs)with 95%confidence intervals(CIs).RESULTS We included a total of 30 RCTs involving 16977 patients.Compared to the control group,rectal indomethacin showed comparable rates of overall PEP(PEP;RR=0.85,95%CI:0.69-1.04,I2=79%)with no statistically significant difference of RR in mild(RR=0.92,95%CI:0.74-1.14),moderate(RR=0.78,95%CI:0.59-1.02),or severe PEP(RR=1.12,95%CI:0.75-1.67).There was also no difference in cases of adverse events(RR=0.97,95%CI:0.69-1.35),abdominal pain(RR=1.14,95%CI:0.80-1.62),bleeding(RR=1.07,95%CI:0.70-1.63),or mortality(RR=0.86,95%CI:0.56-1.33)between the two groups.Subgroup analyses were also performed.CONCLUSION Rectal indomethacin appears to be safe and may offer benefit in selected high-risk patients,though findings should be interpreted with caution due to high heterogeneity.
摘要Objective:This review aims to explore the risk factors for recurrence of nonmuscle-invasive bladder cancer(NMIBC)and evaluate current prevention strategies to provide valuable insights for future clinical management.By systematically analyzing various clinical and pathological characteristics,this review examines their relationship with NMIBC recurrence and proposes effective preventive measures for these factors.Methods:A systematic literature search was conducted through PubMed and Web of Science to identify studies that focus on the risk factors for NMIBC recurrence.A systematic review was conducted to evaluate the statistical significance of various factors influencing recurrence,such as age,sex,body mass index(BMI),diabetes,smoking,surgical techniques,and tumorspecific characteristics.Additionally,current preventive strategies and treatments,such as intravesical drug instillation,adjuvant chemotherapy,and immunotherapy,were assessed.Results:The following factors significantly influence the recurrence risk of NMIBC:age(older patients have a higher recurrence risk due to weakened immune responses and more comorbidities),sex(women tend to experience more aggressive forms and a poorer prognosis following recurrence),BMI and diabetes(obesity and diabetes worsen immune responses and increase inflammation,contributing to higher recurrence rates),smoking(smokers face a higher recurrence risk due to carcinogenic exposure,but quitting significantly reduces the risk),surgical techniques(incomplete transurethral resection of bladder tumor or inadequate postoperative treatments,e.g.,Bacillus Calmette-Guerin[BCG],increase recurrence),tumor characteristics(high-grade and large tumors[especially multifocal]have a higher risk of recurrence),immunotherapy and chemotherapy(BCG is standard for high-risk patients,while newer treatments,such as immune checkpoint inhibitors[e.g.,pembrolizumab]and chemotherapy[e.g.,gemcitabine with docetaxel],are emerging for BCG-unresponsive cases),and biomarkers(biomarkers like tumor DNA in urine or circulating tumor DNA in blood can facilitate early detection of recurrence and help predict recurrence risk).
摘要BACKGROUND Screening can play a role in primary prevention by mitigating modifiable risk factors.However,whether upper gastrointestinal(UGI)endoscopic screening can reduce the burden of modifiable risk factors is unknown.AIM To evaluate the effect of UGI endoscopic screening on modifiable risk factors for cancer and its potential role in primary prevention.METHODS We collected data from 11842 participants in the screening arm(received standard UGI endoscopy)and 12793 participants in the control arm(received abdominal B-ultrasound examination)of a randomized controlled trial.The participants completed questionnaires before and after screening(median interval:6.55 years).Data on three modifiable risk factors including cigarette smoking,alcohol drinking,and unhealthy dietary habits,at both time-points were collected.Logistic regression was applied to assess the effect of UGI endoscopic screening on the cessation and incidence of these three modifiable risk factors.RESULTS UGI endoscopic screening significantly increased the cessation rate of cigarette smoking,alcohol drinking and unhealthy dietary habits[odds ratio(OR)smoking=1.20(1.06-1.36),ORdrinking=1.33(1.19-1.50)and OR_(unhealthy dietary habits)=1.07(1.02-1.13)].Subgroup analysis showed that the cessation effects were dominant among subjects who completed UGI endoscopy,while no significant effects were observed among those who declined endoscopy.Females and individuals aged>60 years were more prone to changes in behavior.Analysis of the incidence of the three modifiable risk factors showed that only the incidence of unhealthy dietary habits was significantly decreased by UGI endoscopic screening[OR=0.85(0.80-0.91)].CONCLUSION UGI endoscopic screening increased the cessation of modifiable risk factors;thus,contributing to primary prevention of cancers.Females and individuals aged>60 years in rural China were more prone to changes in behavior.
摘要Post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis(PEP)is the most common and serious complication following ERCP,with incidence rates ranging from 3%to 15%and up to 40%in high-risk patients.Its multifactorial pathogenesis involves both patient-related and procedure-related factors.Established risk factors include female sex,younger age,sphincter of Oddi dysfunction,previous pancreatitis,difficult cannulation,and pancreatic duct injection.The combination of several risk factors markedly increases the likelihood of PEP,underscoring the need for individualized risk assessment.Preventive strategies have evolved from empirical approaches to evidence-based interventions.Rectal non-steroidal anti-inflammatory drugs and prophylactic pancreatic duct stenting are strongly supported by clinical evidence as effective measures,particularly in high-risk patients.Aggressive intravenous hydration and early precut sphincterotomy have also shown benefit.However,the efficacy of pharmacological agents such as somatostatin,gabexate,and nafamostat mesilate remains inconsistent.Recent advances include the development of risk prediction models and scoring systems that integrate patient and procedural variables,offering moderate predictive accuracy.Ongoing research explores the use of artificial intelligence to improve risk stratification and guide prophylactic strategies.Future efforts should focus on standardizing diagnostic criteria,validating predictive tools,and optimizing combined preventive protocols.Through integrated risk assessment and tailored prevention,the incidence and severity of PEP may be significantly reduced,improving safety and outcomes in ERCP practice.

摘要BACKGROUND Hepatocellular carcinoma(HCC)remains a common malignancy,with surgical intervention being the main curative treatment.Postoperative deep vein thrombosis(DVT)incidence after HCC surgery is significantly high due to major surgical trauma,prolonged bed rest,and patient-specific risk factors such as cirrhosis and coagulation dysfunction.Current DVT prevention strategies,including pharmacological and physical prophylaxis,have reduced effectiveness when used separately.Early mobilization and intermittent pneumatic compression(IPC)have shown potential benefits,but evidence on their combinations remains unclear.AIM To investigate the efficacy and safety of early mobilization combined with IPC for lower extremity DVT prevention after HCC surgery.METHODS A retrospective analysis was conducted on 100 patients who underwent HCC surgery at our hospital from January 2020 to June 2025.Forty-eight patients who received standard care from January 2020 to June 2022 were assigned to the control group,and 52 patients who received early mobilization combined with IPC from July 2022 to June 2025 were assigned to the observation group.The observation group initiated a progressive early mobilization protocol 6-8 hours postoperatively,simultaneously applying IPC(pressure 40-60 mmHg,30-45 minutes per session,twice daily,continued until postoperative day 7).The primary outcome was the incidence of lower extremity DVT.Secondary outcomes included pulmonary embolism(PE)incidence,coagulation parameters(D-dimer,fibrinogen,prothrombin time,activated partial thromboplastin time),lower limb circumference changes,and functional recovery indicators[Barthel Index(BI),Karnofsky Performance Status(KPS)score,independent walking distance].RESULTS The total incidence of lower extremity DVT was 5.8%in the observation group,lower than 18.8%in the control group(P=0.045).D-dimer levels at postoperative days 7 and 14 were lower in the observation group compared to the control group(P=0.002,P=0.001).Calf circumference at postoperative day 7 was smaller in the observation group than the control group(P=0.006).The observation group had earlier time to first ambulation than the control group(P0.05).CONCLUSION This study demonstrated the safety and feasibility of implementing a combined early mobilization and IPC strategy to improve recovery for HCC surgery patients.The combined approach indicated reduced lower extremity DVT incidence,improved functional recovery,and good safety profile.Further prospective randomized controlled trials are needed to establish definitive efficacy and optimize protocol parameters.
摘要Hospital-acquired functional decline(HAFD),even after a successful surgery,is found in up to one-third of the geriatric population.Early and accurate prediction of HAFD can provide timepoints for early intervention to improve postoperative outcomes.While machine learning(ML)offers a promising approach,several pitfalls must be addressed before clinical adoption.When combined with clinically interpretable outputs and continuous model recalibration,ML can support patient-centred decision-making,helping reduce preventable disability,shorten recovery time,and improve overall quality of care for vulnerable hospitalized elders.
摘要Lymphocele is a common postoperative complication following renal transplantation,with reported incidence ranging from 0.6%to 38%.Symptomatic lymphoceles,occurring in 5%-10%of recipients,may cause graft dysfunction through ureteric or vascular compression.This minireview provides a comprehensive synthesis of the epidemiology,pathophysiology,risk factors,prevention,diagnosis,and management of post-transplant lymphoceles.Prevention strategies include meticulous surgical ligation of lymphatics,prophylactic peritoneal fenestration,and delaying the use of mammalian target of rapamycin inhibitors in the early post-transplant period.Diagnosis is best achieved using ultrasound,with computed tomography or magnetic resonance imaging reserved for complex cases.Management follows a stepwise approach:Conservative observation for small asymptomatic collections,percutaneous drainage with or without sclerotherapy for symptomatic cases,and laparoscopic marsupialization for refractory or complicated lymphoceles.Novel techniques,including intraoperative lymphangiography and bioengineered sealants,represent promising future strategies for addressing these challenges.This minireview highlights the importance of integrating surgical refinement,tailored immunosuppression,and emerging technologies to optimize outcomes in renal transplant recipients.

摘要BACKGROUND Acute respiratory tract infections(ARTIs)are a major cause of pediatric morbidity.Daycare centers(DCCs)are high-risk environments where close interpersonal contact facilitates rapid viral transmission.Effective and practical preventive strategies are therefore essential to reduce infection-related burden in these settings.AIM To determine the incidence of ARTIs in DCCs following implementation of a structured protocol designed to mitigate respiratory virus transmission.METHODS A cluster study was conducted in which two centers were centers to either intervention or control groups via lottery.Although allocation was randomized,the study was not designed as a randomized controlled trial;therefore,potential bias and confounding were considered.Participants were followed for 25 weeks.The primary outcome was physician-diagnosed ARTIs per 100 child-weeks.Incidence rate ratios(IRRs)with 95% CIs were estimated using Poisson regression with a log link and person-time offset,adjusting for covariates under the intention-to-treat principle.Results cautious interpretation Due to limited clusters,results require cautious interpretation.Statistical significance was defined as P<0.05.RESULTS A total of 223 children(149 intervention,74 control)across 2 clusters were enrolled.By week 25,the cumulative proportion of ARTIs was 18.1%in the intervention group compared with 60.8%in the control group.The incidence rate of ARTIs was lower in the intervention group,with adjusted rates of 1.09 per 100 child-weeks vs 13.00 per 100 child-weeks.The adjusted IRR was 0.14(95%CI:0.09-0.22;P<0.001),suggesting an observed difference in incidence between groups under the study conditions.CONCLUSION Protocol implementation was associated with a lower observed incidence of ARTIs under the study conditions.However,interpretation is constrained by the study design,the small number of clusters,and potential sources of bias.Larger,well-designed randomized studies are required to further evaluate this association in daycare settings.
