Disease deemed to be critical or severe at detection requires appropriate medical follow-up. This article examined the self-reported outcomes of individuals who had undergone community-based cardiovascular screening and had critical findings for abdominal aortic aneurysm (AAA) or carotid artery stenosis (CAS). Methods: Over 390,000 screening records for AAA and over 490,000 screening records for CAS were reviewed to identify individuals with critical screening findings. A critical AAA is defined as an aneurysm ≥ 5cm and critical CAS is defined as a hemodynamically significant stenosis with recorded peak systolic velocities of ≥300 cm/s, in this population. Identified individuals were then contacted via phone and surveyed about the medical care they received after their screening. Results: Review of the screening records found a prevalence of critical AAA findings of 0.037% (146 participants) and critical CAS findings of 0.12% (579 participants). 61% of participants with critical findings were reached for follow-up from both groups. Over 96% of participants with critical AAA and over 92% of participants with critical CAS had some forms of medical follow-up. Conclusions: Community-based cardiovascular screening has the ability to detect critical levels of disease. Findings of critical disease in the reviewed population are similar to the findings from previously published studies. Importantly, medical treatment received by those who seek follow-up appears to be consistent with recommended treatment guidelines. Identification and management of critical disease represent meaningful public and individual health benefits and the possibility of cost-savings.展开更多

Therefore a community-based screening research was conducted in order to determine the prevalence of CKD and prediabetes, and to analyze associated risk factors of CKD and prediabetes in a city of Southern China.Methods A total of 7801 community residents aged 18 year and older from 6 communities were screened by a stratified random cluster sampling method. An estimated glomerular filtration rate （eGFR）, albuminuria, fasting plasma glucose （FPG）, and homeostatic model assessment of insulin resistance （HOMA-IR） were measured. Age-standardized prevalence was calculated by the direct method with the use of data on the population distribution in China in 2006. Multivariate logistic analysis was used to analyze the risk factors of CKD and ＂prediabetes, and association of insulin resistance （IR） with CKD and prediabetes was analyzed.Results The age-standardized prevalence of CKD was 12.5%, eGFR 〈60 ml.min^-1.1.73 m2 was 2.7% and ACR （albumin to creatinine ratio） 〉30 mg/g was 10.3%. The age-standardized prevalence of prediabetes was 12.1%. Logistic regression suggests that IR was a common independent risk factor of CKD and prediabetes. Further analysis show that HOMA-IR was increased with the aggravation of kidney injury and FPG. Conclusion CKD and prediabetes have become a major public health problem in Zhuhai, Southern China; insulin resistance may be an important risk factor.展开更多

Identification of both disease and risk factors (e.g. high cholesterol, high blood pressure, diabetes, etc.) creates an opportunity for treatment and management to reduce and prevent cardiovascular events from occurring. Methods: Over 230,000 screening records for individuals who had undergone carotid artery stenosis (CAD), abdominal aortic aneurysm (AAA), or peripheral artery disease (PAD) screening were reviewed. Participants were stratified based on self-reported risk factors as having no risk factors, one risk factor, or two or more risk factors. Self-reported risk factors were also compared with results of screening for blood pressure, blood glucose, and lipid level status. Results: Abnormal findings of CAS, AAA, and PAD were all uncovered in individuals who self-reported as having no traditional risk factors. These abnormal findings included those defined as severe. The review of self-reported risk factors for accuracy demonstrated varying levels of inaccuracies in both under and over-reporting of risk factors. Conclusions: Community-based cardiovascular screening may result in the identification of cardiovascular disease in individuals with no established risk factors. While the underreporting of risk factors has also be demonstrated, it is clear that further research is warranted to better understand the presence of disease in the absence of risk factors.展开更多

文摘Background: Community-based cardiovascular screening has the opportunity to detect critical cardiovascular disease and positively affect public health outcomes. Disease deemed to be critical or severe at detection requires appropriate medical follow-up. This article examined the self-reported outcomes of individuals who had undergone community-based cardiovascular screening and had critical findings for abdominal aortic aneurysm (AAA) or carotid artery stenosis (CAS). Methods: Over 390,000 screening records for AAA and over 490,000 screening records for CAS were reviewed to identify individuals with critical screening findings. A critical AAA is defined as an aneurysm ≥ 5cm and critical CAS is defined as a hemodynamically significant stenosis with recorded peak systolic velocities of ≥300 cm/s, in this population. Identified individuals were then contacted via phone and surveyed about the medical care they received after their screening. Results: Review of the screening records found a prevalence of critical AAA findings of 0.037% (146 participants) and critical CAS findings of 0.12% (579 participants). 61% of participants with critical findings were reached for follow-up from both groups. Over 96% of participants with critical AAA and over 92% of participants with critical CAS had some forms of medical follow-up. Conclusions: Community-based cardiovascular screening has the ability to detect critical levels of disease. Findings of critical disease in the reviewed population are similar to the findings from previously published studies. Importantly, medical treatment received by those who seek follow-up appears to be consistent with recommended treatment guidelines. Identification and management of critical disease represent meaningful public and individual health benefits and the possibility of cost-savings.

文摘Background The prevalence of chronic kidney disease （CKD） and prediabetes has increased in China, and at different rates in different locations. Therefore a community-based screening research was conducted in order to determine the prevalence of CKD and prediabetes, and to analyze associated risk factors of CKD and prediabetes in a city of Southern China.Methods A total of 7801 community residents aged 18 year and older from 6 communities were screened by a stratified random cluster sampling method. An estimated glomerular filtration rate （eGFR）, albuminuria, fasting plasma glucose （FPG）, and homeostatic model assessment of insulin resistance （HOMA-IR） were measured. Age-standardized prevalence was calculated by the direct method with the use of data on the population distribution in China in 2006. Multivariate logistic analysis was used to analyze the risk factors of CKD and ＂prediabetes, and association of insulin resistance （IR） with CKD and prediabetes was analyzed.Results The age-standardized prevalence of CKD was 12.5%, eGFR 〈60 ml.min^-1.1.73 m2 was 2.7% and ACR （albumin to creatinine ratio） 〉30 mg/g was 10.3%. The age-standardized prevalence of prediabetes was 12.1%. Logistic regression suggests that IR was a common independent risk factor of CKD and prediabetes. Further analysis show that HOMA-IR was increased with the aggravation of kidney injury and FPG. Conclusion CKD and prediabetes have become a major public health problem in Zhuhai, Southern China; insulin resistance may be an important risk factor.

文摘Diabetic retinopathy(DR)is a leading cause of vision loss among working-age populations,with early screening significantly reducing the risk of blindness.However,resource-limited regions often face challenges in DR screening due to a shortage of ophthalmologists.This study reports the implementation and outcomes of the Chinese local standard DB52/T 1726-2023,Regulations for the application of diabetic retinopathy screening artificial intelligence,in Cambodian healthcare institutions.A pilot DR screening program with independent operational capability is established by providing a non-mydriatic fundus camera and deploying a localized diabetic retinopathy artificial intelligence(DR-AI)screening platform at the Cambodia-Kingdom Friendship Hospital in Phnom Penh,along with comprehensive training.From January to August 2025,a total of 565 patients with type 2 diabetes were screened,yielding a DR detection rate of 26.0%(147 cases).Research findings demonstrate that applying mature Chinese DR-AI screening standards and technological solutions through international collaboration in regions with a scarcity of ophthalmic professionals is both feasible and effective.This project serves as a reference for promoting DR-AI in resource-constrained countries and regions,highlighting its significant potential to leverage AI in addressing the global burden of chronic diseases and advancing the modernization of health systems.
文摘Introduction: Community-based cardiovascular screening presents an opportunity to detect the presence of cardiovascular disease in individuals who report having no traditional risk factors, and also to identify the presence of those risk factors in those who are unaware of their health status. Identification of both disease and risk factors (e.g. high cholesterol, high blood pressure, diabetes, etc.) creates an opportunity for treatment and management to reduce and prevent cardiovascular events from occurring. Methods: Over 230,000 screening records for individuals who had undergone carotid artery stenosis (CAD), abdominal aortic aneurysm (AAA), or peripheral artery disease (PAD) screening were reviewed. Participants were stratified based on self-reported risk factors as having no risk factors, one risk factor, or two or more risk factors. Self-reported risk factors were also compared with results of screening for blood pressure, blood glucose, and lipid level status. Results: Abnormal findings of CAS, AAA, and PAD were all uncovered in individuals who self-reported as having no traditional risk factors. These abnormal findings included those defined as severe. The review of self-reported risk factors for accuracy demonstrated varying levels of inaccuracies in both under and over-reporting of risk factors. Conclusions: Community-based cardiovascular screening may result in the identification of cardiovascular disease in individuals with no established risk factors. While the underreporting of risk factors has also be demonstrated, it is clear that further research is warranted to better understand the presence of disease in the absence of risk factors.

文摘Rapid screening of inorganic arsenic(iAs)in groundwater used for drinking by hundreds of millions of mostly rural residents worldwide is crucial for health protection.Most commercial field test kits are based on the Gutzeit reaction that uses mercury-based reagents for color development,an environmental concern that increasingly limits its utilization.This study further improves the Molybdenum Blue(MB)colorimetric method to allow for faster screening with more stable reagents.More importantly,a portable three-channel colorimeter is developed for screening iAs relative to the WHO drinking water guideline value(10μg/L).Adding the reducing reagents in sequence not only prolongs the storage time to>7 days,but also accelerates the color development time to 6 min in conjunction with lowering the H_(2)SO_(4) concentration in chromogenic reagents.The optimal pH ranges from 1.2 to 1.3 and is achieved by acidifying groundwater to 1%(V/V)HCl.With detection limits of 3.7μg/L for inorganic arsenate(iAs(V))and 3.8μg/L for inorganic arsenite(iAs(Ⅲ)),testing groundwater with-10μg/L of As has a precision<20%.The method works well for a range of phosphate concentrations of 48-950μg/L(0.5-10μmol/L).Concentrations of total_iAs(6-300μg/L),iAs(V)(6-230μg/L)and iAs(Ⅲ)(0-170μg/L)for 14 groundwater samples from Yinchuan Plain,Pearl River Delta,and Jianghan Plain,are in excellent agreements(linear regression slope:0.969-1.029)with the benchmark methods.The improved chemistry here lays the foundation for the MB colorimetric method to become a commercially viable screening tool,with further engineering and design improvement of the colorimeter.

文摘This study investigated environmental distribution and human exposure of polycyclic aromatic hydrocarbons(PAHs)and their derivatives in one Chinese petroleum refinery facility.It was found that,following with high concentrations of 16 EPA PAHs(∑Parent-PAHs)in smelting subarea of studied petroleum refinery facility,total derivatives of PAHs[named as XPAHs,including nitro PAHs(NPAHs),chlorinated PAHs(Cl-PAHs),and brominated PAHs(Br-PAHs)]in gas(mean=1.57×10^(4)ng/m^(3)),total suspended particulate(TSP)(mean=4.33×10^(3) ng/m^(3))and soil(mean=4.37×10^(3) ng/g)in this subarea had 1.76-6.19 times higher levels than those from other subareas of this facility,surrounding residential areas and reference areas,indicating that petroleum refining processes would lead apparent derivation of PAHs.Especially,compared with those in residential and reference areas,gas samples in the petrochemical areas had higher∑NPAH/∑PAHs(mean=2.18),but lower∑Cl-PAH/∑PAHs(mean=1.43×10^(-1))and∑Br-PAH/∑PAHs ratios(mean=7.49×10^(-2)),indicating the richer nitrification of PAHs than chlorination during petrochemical process.The occupational exposure to PAHs and XPAHs in this petroleum refinery facility were 24-343 times higher than non-occupational exposure,and the ILCR(1.04×10^(-4))for petrochemical workers was considered to be potential high risk.Furthermore,one expanded high-resolution screening through GC Orbitrap/MS was performed for soils from petrochemical area,and another 35 PAHs were found,including alkyl-PAHs,phenyl-PAHs and other species,indicat-ing that profiles and risks of PAHs analogs in petrochemical areas deserve further expanded investigation.
文摘Liver transplantation(LT)is the definitive treatment for end-stage liver disease,acute liver failure,and liver cancer.Although advancements in surgical techniques,postoperative care,and immunosuppressive therapies have significantly improved outcomes,the long-term use of immunosuppression has increased the risk of complications,including infections,cardiovascular disease,and cancer.Among these,de novo malignancies(DNMs)are a major concern,accounting for 20%-25%of deaths in LT recipients surviving beyond the early post-transplant period.Non-melanoma skin cancers,particularly squamous cell carcinoma are the most prevalent DNMs.Other significant malignancies include Kaposi's sarcoma,post-transplant lymphoproliferative disorders,and various solid organ cancers,including head and neck cancers.Compared to the general population,LT patients face a twofold increase in solid organ malignancies and a 30-fold increase in lymphoproliferative disorders.Risk factors for DNM include chronic immunosuppression,alcohol or tobacco use,viral infections,and underlying liver disease.Emerging evidence emphasizes the importance of tailored cancer screening and prevention strategies,including regular dermatological examinations,targeted screenings for high-risk cancers,and patient education on lifestyle modifications.Early detection through enhanced surveillance protocols has been shown to improve outcomes.Management of DNMs involves a combination of standard oncological therapies and adjustments to immunosuppressive regimens,with promising results from the use of mTOR inhibitors in select patients.The review highlights the critical need for ongoing research to refine risk stratification,optimize screening protocols,and improve treatment approaches to mitigate the burden of DNMs in LT recipients.By implementing personalized preventive and therapeutic strategies,we can enhance long-term outcomes and quality of life for this vulnerable population.

文摘Accurate prediction of drug-target interactions(DTIs)plays a pivotal role in drug discovery,facilitating optimization of lead compounds,drug repurposing and elucidation of drug side effects.However,traditional DTI prediction methods are often limited by incomplete biological data and insufficient representation of protein features.In this study,we proposed KG-CNNDTI,a novel knowledge graph-enhanced framework for DTI prediction,which integrates heterogeneous biological information to improve model generalizability and predictive performance.The proposed model utilized protein embeddings derived from a biomedical knowledge graph via the Node2Vec algorithm,which were further enriched with contextualized sequence representations obtained from ProteinBERT.For compound representation,multiple molecular fingerprint schemes alongside the Uni-Mol pre-trained model were evaluated.The fused representations served as inputs to both classical machine learning models and a convolutional neural network-based predictor.Experimental evaluations across benchmark datasets demonstrated that KG-CNNDTI achieved superior performance compared to state-of-the-art methods,particularly in terms of Precision,Recall,F1-Score and area under the precision-recall curve(AUPR).Ablation analysis highlighted the substantial contribution of knowledge graph-derived features.Moreover,KG-CNNDTI was employed for virtual screening of natural products against Alzheimer's disease,resulting in 40 candidate compounds.5 were supported by literature evidence,among which 3 were further validated in vitro assays.
文摘Helicobacter pylori(H.pylori)infection induces pathological changes via chronic inflammation and virulence factors,thereby increasing the risk of gastric cancer development.Compared with invasive examination methods,H.pylori-related serum indicators are cost-effective and valuable for the early detection of gastric cancer(GC);however,large-scale clinical validation and sufficient understanding of the specific molecular mechanisms involved are lacking.Therefore,a comprehensive review and analysis of recent advances in this field is necessary.In this review,we systematically analyze the relationship between H.pylori and GC and discuss the application of new molecular biomarkers in GC screening.We also summarize the screening potential and application of anti-H.pylori immunoglobulin G and virulence factor-related serum antibodies for identifying GC risk.These indicators provide early warning of infection and enhance screening accuracy.Additionally,we discuss the potential combination of multiple screening indicators for the comprehensive analysis and development of emerging testing methods to improve the accuracy and efficiency of GC screening.Although this review may lack sufficient evidence due to limitations in existing studies,including small sample sizes,regional variations,and inconsistent testing methods,it contributes to advancing personalized precision medicine in high-risk populations and developing GC screening strategies.

文摘The high porosity and tunable chemical functionality of metal-organic frameworks(MOFs)make it a promising catalyst design platform.High-throughput screening of catalytic performance is feasible since the large MOF structure database is available.In this study,we report a machine learning model for high-throughput screening of MOF catalysts for the CO_(2) cycloaddition reaction.The descriptors for model training were judiciously chosen according to the reaction mechanism,which leads to high accuracy up to 97%for the 75%quantile of the training set as the classification criterion.The feature contribution was further evaluated with SHAP and PDP analysis to provide a certain physical understanding.12,415 hypothetical MOF structures and 100 reported MOFs were evaluated under 100℃ and 1 bar within one day using the model,and 239 potentially efficient catalysts were discovered.Among them,MOF-76(Y)achieved the top performance experimentally among reported MOFs,in good agreement with the prediction.
文摘Diabetic retinopathy(DR)remains a leading cause of vision impairment and blindness among individuals with diabetes,necessitating innovative approaches to screening and management.This editorial explores the transformative potential of artificial intelligence(AI)and machine learning(ML)in revolutionizing DR care.AI and ML technologies have demonstrated remarkable advancements in enhancing the accuracy,efficiency,and accessibility of DR screening,helping to overcome barriers to early detection.These technologies leverage vast datasets to identify patterns and predict disease progression with unprecedented precision,enabling clinicians to make more informed decisions.Furthermore,AI-driven solutions hold promise in personalizing management strategies for DR,incorpo-rating predictive analytics to tailor interventions and optimize treatment path-ways.By automating routine tasks,AI can reduce the burden on healthcare providers,allowing for a more focused allocation of resources towards complex patient care.This review aims to evaluate the current advancements and applic-ations of AI and ML in DR screening,and to discuss the potential of these techno-logies in developing personalized management strategies,ultimately aiming to improve patient outcomes and reduce the global burden of DR.The integration of AI and ML in DR care represents a paradigm shift,offering a glimpse into the future of ophthalmic healthcare.
文摘Colorectal cancer(CRC)is the third most commonly diagnosed cancer and the second leading cause of cancer death worldwide.The leading risk factors for CRC include male gender,age over 50,family history,obesity,tobacco smoking,alco-hol consumption,and unhealthy diet.CRC screening methods vary considerably between countries and depend on incidence,economic resources and healthcare structure.Important aspects of screening include adherence,which can vary signi-ficantly across ethnic and socioeconomic groups.Basic concepts of CRC screening include pre-stratification of patients by identifying risk factors and then using fecal immunochemical test or guaiac-based fecal occult blood test and/or colono-scopy or radiologic imaging techniques.Technological capabilities for CRC scree-ning are rapidly evolving and include stool DNA test,liquid biopsy,virtual colo-nography,and the use of artificial intelligence.A CRC prevention strategy should be comprehensive and include active patient education along with targeted imple-mentation of screening.
文摘BACKGROUND Neonatal screening(NS)is a public health policy to identify genetic pathologies such as cystic fibrosis(CF),sickle cell disease,and other diseases.Sickle cell disea-se is the comprehensive term for a group of hemoglobinopathies characterized by the presence of hemoglobin S.CF is an autosomal recessive multisystemic disease with pathophysiology involving deleterious mutations in the transmembrane re-gulatory gene that encodes a protein that regulates the activity of chloride and sodium channels in the cell surface epithelium.NS is crucial for early diagnosis and management,which ensures a better quality of life.AIM To report a case of the coexistence of sickle cell anemia(SCA)and CF and perform an integrative literature review.METHODS This is an observational study and a review of the literature focusing on two rare genetic pathologies identified simultaneously in NS from the perspective of a clinical case.The authors identified only 5 cases of SCA associated with CF.No clinical trials or review articles were identified considering the rarity of the coexistence of these two pathologies.RESULTS Herein,the authors reported the case of a girl who after undergoing NS on day 8 of life was diagnosed with SCA with an alteration in the dosage of immunoreactive trypsin.The diagnosis of CF was confirmed by the Coulometry Sweat Test.The rarity of the co-occurrence of these two severe genetic pathologies(CF and SCA)is a challenge for medical science.CONCLUSION This study adds to the few case reports present in the literature that highlight the identification of two severe diseases via NS.
文摘BACKGROUND The Asia-Pacific Colorectal Screening(APCS)score was designed with the purpose of distinguishing individuals at high risk(HR)for colorectal advanced neoplasia(AN).Traditional Chinese medicine(TCM)constitution was also linked with colorectal cancer(CRC).AIM To integrate the APCS score with TCM constitution identification as a new algorithm to screen for CRC.METHODS A cross-sectional multicenter study was carried out in three hospitals,enrolling 1430 patients who were asymptomatic and undergoing screening colonoscopy from 2022 to 2023.Patients were considered to have average risk,moderate risk,or HR with their APCS score.Odd ratios assessed the relationship between TCM constitution and disease progression.A TCM constitution risk score was created.The sensitivity and specificity of the new algorithm were calculated to evaluate diagnostic performance in detecting advanced adenoma(AA),CRC,and AN.RESULTS Of the 1430 patients,370(25.9%)were categorized as average risk,755(52.8%)as moderate risk,and 305(21.3%)as HR.Using the combined APCS score and the TCM constitution(damp-heat,qi-deficiency,yang-deficiency,phlegm-dampness,and inherited special constitution as positive)algorithm,72.2%of patients with AA and 73.7%of patients with AN were detected.Compared with the APCS score alone,the new algorithm significantly improved the sensitivity for screening AA[72.2%,95%confidence interval(CI):64.4%-80.0%vs 49.2%,95%CI:40.5%-57.9%]and AN(73.7%,95%CI:66.4%-81.1%vs 51.1%,95%CI:42.7%-59.5%).CONCLUSION The combination of APCS and TCM constitution identification questionnaires was valuable in identifying Chinese individuals who were asymptomatic for colorectal screening prioritization.
