Colonoscopy remains the cornerstone of colorectal cancer prevention and survei-llance,but the procedure’s effectiveness is entirely dependent upon various quali-ty indicators,such as detection rates,withdrawal time,adequate bowel prepara-tion,cecal intubation rate and patient outcomes.Despite progress in endoscopic techniques,challenges persist in maintaining endoscopists’consistent perfor-mance and improving quality metrics.Artificial intelligence(AI)has emerged as a“game changer”in the gastroenterology field,offering the opportunity to signifi-cantly increase colonoscopy quality.This review highlights the role of AI-driven technologies such as deep learning,computer vision,and real-time feedback me-chanisms in optimizing key quality indicators of colonoscopy.The implementa-tion of AI in colonoscopy may reduce human error,improve endoscopist’s consis-tency in real-time decision making,ensuring higher reliability and standardiza-tion during the procedure.Furthermore,AI has the potential to reshape how en-doscopists perform and evaluate procedures,while improved lesion characte-rization may enable more precise selection for resection,reducing morbidity and the incidence of interval cancers.The review also addresses challenges and limi-tations in AI integration,including cost-effectiveness and its impact on endosco-pist training.AI holds substantial promise for advancing colonoscopy quality and elevating overall patient care,paving the way for more effective and personalized medical approaches. 展开更多

Additive Manufacturing(AM)can provide customized parts that conventional techniques fail to deliver.One important parameter in AM is the quality of the parts,as a result of the material extrusion 3D printing(3D-P)procedure.This can be very important in defense-related applications,where optimum performance needs to be guaranteed.The quality of the Polyetherimide 3D-P specimens was examined by considering six control parameters,namely,infill percentage,layer height,deposition angle,travel speed,nozzle,and bed temperature.The quality indicators were the root mean square(Rq)and average(Ra)roughness,porosity,and the actual to nominal dimensional deviation.The examination was performed with optical profilometry,optical microscopy,and micro-computed tomography scanning.The Taguchi design of experiments was applied,with twenty-five runs,five levels for each control parameter,on five replicas.Two additional confirmation runs were conducted,to ensure reliability.Prediction equations were constructed to express the quality indicators in terms of the control parameters.Three modeling approaches were applied to the experimental data,to compare their efficiency,i.e.,Linear Regression Model(LRM),Reduced Quadratic Regression Model,and Quadratic Regression Model(QRM).QRM was the most accurate one,still the differences were not high even considering the simpler LRM model. 展开更多

Accurate vehicle localization is essential for safety-critical vehicular ad hoc networks(VANETs),including emergency response,navigation,traffic monitoring,and cooperative driving.However,conventional GPS/GNSS positioning systems have often shown degradation in tunnels,dense urban corridors,and non-line-of-sight(NLOS)environments,where satellite visibility and signal reliability are limited.This paper proposes a calibrated Link Quality Indicator(LQI)-based closed-form localization framework for partially connected Roadside Unit(RSU)-assisted VANETs.The proposed framework first calibrates the LQI-to-range relationship using numerical regression parameters and then converts accepted LQI observations into distance estimates.The distances are processed through a variance-aware weighted least squares(WLS)estimator,after which scalar consistency refinement is applied to improve the geometric consistency of the final position estimate.Partial connectivity is explicitly modeled using communication radius,LQI-threshold,and packet-reception constraints,rather than assuming that all vehicles and anchors are fully connected.The proposed method is evaluated against least squares(LS),WLS,RSSI-WLS,Extended Kalman Filter(EKF),Unscented Kalman Filter(UKF),Particle Filter(PF),cooperative localization,hybrid GNSS/INS/RSS fusion,and machine-learning-based localization baselines.The evaluation includes Monte Carlo simulations under shadowing,fading,packet loss,anchor-geometry,and NLOS conditions,together with confidence interval,statistical-significance,runtime,ablation,and sensitivity analyses.In addition,trace-driven validation is performed using the NGSIM US-101 real-world vehicle trajectory dataset.The NGSIM dataset provides real vehicle mobility traces,while LQI observations are generated using the calibrated LQI-distance model because the dataset does not contain physical LQI measurements.In the 100-vehicle case,throughput improves from 0.614 to 1.169 successful localizations/s compared with LS,corresponding to a 90.39%gain and from 0.591 to 1.169 successful localizations/s compared with WLS,corresponding to a 97.80%gain.In the NGSIM trace-driven experiment,the proposed method achieves RMSE values of 2.39,2.55,and 3.14 m for 10,50,and 100 vehicles,respectively.These results indicate that calibrated LQI-based localization provides a low-cost,infrastructure-compatible,and computationally efficient positioning framework for ITS and safety-critical VANET applications. 展开更多

Alcohol,total sugar,total acid,and total phenol contents are the main indicators of wine quality detection.This study aims to establish simultaneous analysis models for the four indicators through near-infrared(NIR)spectroscopy with wavelength optimization.A Norris derivative filter(NDF)platform with multiparameter optimization was established for spectral pretreatment.The optimal parameters(i.e.,derivative order,number of smoothing points,and number of differential gaps)were(2,9,3)for alcohol,(1,19,5)for total sugar,(1,17,11)for total acid,and(1,1,1)for total phenol.The equidistant combinationpartial least squares(EC-PLS)was used for large-scale wavelength screening.The wavelength step-by-step phaseout PLS(WSP-PLS)and exhaustive methods were used for secondary optimization.The final optimization models for the four indicators included 7,10,15,and 13 wavelengths located in the overtone or combination regions,respectively.In an independent validation,the root mean square errors,correlation coefficient for prediction(i.e.,SEP and RP),and ratio of performance-to-deviation(RPD)were 0.41 v/v,0.947,and 3.2 for alcohol;1.48 g/L,0.992,and 6.8 for total sugar;0.68 g/L,0.981,and5.1 for total acid;and 0.181 g/L,0.948,and 2.9 for total phenol.The results indicate high correlation,low error,and good overall prediction performance.Consequently,the established reagent-free NIR analytical models are important in the rapid and real-time quality detection of the wine fermentation process and finished products.The proposed wavelength models provide a valuable reference for designing small dedicated instruments. 展开更多

Evidence is not homogeneous on indicators able to monitor and assess qualityperformance for organ donation. This may be related to differences in healthcareorganizations among countries but also to the scarcity of data on this topic so far.In the present review, we assessed available evidence on quality metrics in solidorgan procurement in the United States and in Europe by means of a PubMedsearch. Evidence was summarized according to countries, considering that thedonation and transplantation systems differ from country to country. In UnitedStates, the assessment of these indicators is periodically performed by the nationalnetwork for organ sharing to evaluate the performance of each Organ ProcurementOrganization (OPO). Quality metrics consider several factors, in primispopulation characteristics (i.e. race/ethnicity, age, socio-economic status). That iswhy the assessment of each OPO performance relies on several quality metrics,not only one single indicator. In Europe, quality improvement programs representa structural element of organ and transplant system in several countries, but fewpapers have to date addressed the results obtained by a quality improvementprogram based on indicators. In Poland, the use of quality indicators and improvementprocedures were associated with better results in those hospitals whichimplemented these programs in respect to hospitals who did not. In TuscanyRegion (Italy) the implementation of a monitoring and reporting approach basedon indicators by the Regional Transplant Center was associated with an increasedin transplant and donation activity (especially in cDCD donors). According toavailable evidence, the development of a method for quality assessment andquality improvement has been recognized as pivotal for donation and transplantauthorities to identify key interventions either at national and/or hospital levels. 展开更多

BACKGROUND Although transarterial chemoembolization(TACE)is an effective treatment for liver cancer,clinical practice has shown that many patients experience significant psychological distress following the procedure,which can hinder postoperative recovery and prognosis.Therefore,effective and evidence-based interventions are urgently needed to address this issue.AIM To evaluate the impact of nursing quality-sensitive indicators combined with mindfulness-based stress reduction(MBSR)interventions in patients undergoing TACE.METHODS A total of 84 patients who underwent TACE from June 2022 to March 2024 were enrolled in the study.They were randomly assigned to either the observation group(n=42),which received nursing quality-sensitive indicator-based care combined with MBSR intervention,or the control group(n=42),which received routine care combined with MBSR intervention.Psychological stress response levels[assessed using the Trait Meta-Mood Scale(TMMS)],coping strategies[measured with the Jalowiec Coping Scale(JCS)],quality of care[evaluated using the Perceived Nursing Service Quality(PNSQ)scale],and overall patient satisfaction were compared between the two groups.RESULTS After 4 weeks,the observation group demonstrated significantly higher TMMS scores,as well as increased optimism,support-seeking,bravery,PNSQ scores,and satisfaction(P<0.05).In contrast,scores for selfdependence,conservatism,resignation,and avoidance in the JCS were significantly lower in the observation group than in the control group(P<0.05).CONCLUSION The combination of nursing quality-sensitive indicators and MBSR intervention in TACE patients not only reduces psychological stress and encourages a more positive attitude toward illness but also enhances nursing quality and improves the overall patient experience. 展开更多

Objective This study aimed to examine the implementation processes and system-level outcomes associated with the national adoption of the Registered Nurses’Association of Ontario(RNAO)pressure injury prevention Best Practice Guideline across high-complexity public hospitals in Chile,from a Best Practice Spotlight Organization®(BPSO®)Host Model perspective.Methods This study universe included all institutions incorporated into the national BPSO Host Ministry of Health(MINSAL)program between 2018 and 2022(n=29),integrating BPSO®s from all implementation stages that remained active during the 2023–2024 study period.Quantitative data were obtained from aggregated Nursing Quality Indicators for Reporting and Evaluation(NQuIRE®).Qualitative data were derived from annual institutional implementation reports and analyzed using directed content analysis guided by an implementation science framework.Results Eighteen high-complexity public hospitals submitted complete datasets,of which eleven reported indicators specific to the Pressure Injury Prevention guideline.Improvements were observed across all process indicators,including risk assessment at admission(+2.3%),risk reassessment(+7.9%),and use of pressure-redistributing support surfaces(+4.6%).Although 30.75%of patients were classified as moderate or high risk,pressure injury incidence remained stable at 1.2%–1.3%,well below global pooled estimates.Pioneer hospitals demonstrated consistently higher adherence to preventive processes and lower pressure injury incidence compared with later adopters.Qualitative findings identified leadership,stakeholder engagement,governance structures,and standardized monitoring as key enablers of implementation,while challenges persisted in sustaining bedside practice change and patient engagement.Conclusions A Host-led national implementation strategy can strengthen adherence to evidence-informed pressure injury prevention practices,reduce system-level variability,and sustain low incidence across a public hospital network.The Chilean BPSO®Host model illustrates how coordinated governance,standardized indicators,and structured implementation support can scale evidence-based practice in middle-income health systems. 展开更多

Obesity and global warming are two major challengesthat affect communities’health and quality of life.Providing good walking environments,with appropriate pedestrian infrastructure,green areas and access to commercial retail and transport hubs favour liveable,healthy,and sustainable cities.The Lisbon City Hall has implemented an intervention program in the public space as a strategy to improve environmental quality and mitigate the effects of climate change.The program“A square in each neighbourhood”intends not only to reinforce the economic base of Lisbon,namely tourism,restaurants,commerce,and creative activities but also to promote physical activity and improve the quality of living of all citizens.For studying the impact of the public space quality on the walking environment,Campolide,a typical Lisbon neighbourhood,Portugal,which includes one of the requalified squares,was selected.A two-step methodology based on spatial modelling is proposed.In the first step,the public space quality was evaluated based on a set of 13 urban quality attributes.Attributes,intended for the street level,were collected from open data platforms and complemented with a field survey.Then,through spatial analysis,these attributes were used to build the Pedestrian Environment Quality Indicator and the Priority Intervention Indicator.Using these indicators,walking-friendly streets were mapped and the most critical sites that require priority intervention were identified to prepare for the requalification planning process.The street with the highest quality in the study area according to the dimensions evaluated-connectivity,convenience,comfort,cleanliness,and conviviality-has a great offer of trees,bus stops,commercial establishments,commercial diversity,crossings,paper bins/eco points and esplanades.On the opposite side of the rank,the street with the lowest quality has no trees or green areas,transport stops,benches and tables,or commercial activity.The urban quality indicators constitute a helpful tool for city planners and policymakers when planning sustainable living neighbourhoods. 展开更多

The present analysis provided the quality assessment of 65 Continuous Operating Reference Stations(CORS) situated in and around Mexico using the data of about ten years(January 2010 to January 2020).To accomplish the assessment,we considered 4 quality indexes for performing the quality check,incluing the multipath effect on L1 and L2 bands,signal-to-noise ratio in both bands,cycle slips,and integrity.Meanwhile,a new reference parameter named regio nal values for Mexico(RVM) was calculated for the stations situated in Mexico.Additionally,an exhaustive analysis of the quality indicators in the worst and best cases was performed.The signal degradation was proved by a long-term time series and cru stal defo rmation analysis in GAMIT/GLOBK platform.The results showed a stro ng correlation between integrity,cycle slips and daily observations time,and the multipath effect is strong in the case of outdated systems.The study indicates that the estimated quality indexes and values could be the basis for establishing new CORS in Mexico,and the errors corrections which cannot be mitigated in the postprocessing stage would greatly help utilize the data for different scientific applications.The results were supported by deformation analysis in part of Baja California Peninsula in Mexico indicating northern and eastern velocity vector of -3.08±0.02 mm/yr,-7.85±0.02 mm/yr and-0.07±0.03 mm/yr,-9.33±0.02 mm/yr respectively at MPR1 and INEG stations. 展开更多

This study analyzes the role of financial development(FD)on the impact of technologi-cal innovation(TI)on six environmental quality indicators for the 25 economies that are part of the Organization for Economic Cooperation and Development for the period from 2000 to 2019.We use a two-step dynamic generalized method of moments approach to understand this relationship.The results show that FD augments the posi-tive effects of TI on four of the six environmental indicators,namely ecological foot-print,adjusted net savings,pressure on nature,and environmental performance.However,no significant effects on environmental sustainability and environmental vulnerability indices were found.When considering all of the environmental quality indicators,TI appears to enhance environmental quality.We find evidence to support the existence of the environmental Kuznets curve in the context of each environmen-tal indicator and economic growth.Moreover,FD and energy consumption appear to accelerate environmental degradation.Based on these results,FD should be viewed as an important parameter in designing policies for innovation to achieve the goal of net-zero carbon emissions.Highlights.Technological innovation and environmental quality nexus is studied.The moderating role of financial development is analyzed.Six different environmental quality indicators are used for OECD countries.Financial development intensifies the environmental benefits of innovation.•The EKC hypothesis is confirmed for all six environmental indicators. 展开更多

Endoscopic resection,particularly endoscopic submucosal dissection(ESD),is widely used as a standard treatment modality for early gastric cancer(EGC)when the risk of lymph node metastasis is negligible.Compared with surgical gastrectomy,ESD is a minimally invasive procedure with additional advantages,such as preservation of the entire stomach and maintenance of the patient’s quality of life.However,not all patients achieve curative resection after ESD of EGC.Several patients require surgical gastrectomy after ESD to achieve a curative treatment.Additional surgery after ESD,owing to non-curative resection,places considerable emotional and financial burdens on patients.Recently,as the number of endoscopists performing ESD has increased,the rate of non-curative resection after ESD has increased correspondingly.In order to decrease the non-curative resection rate,as well as determine the ideal rate of non-curative resection after ESD,it is time to consider quality indicators for the outcomes of ESD for EGC. 展开更多

In this paper, some indices of sulfide, organic carbon, oil and heavy metals （copper, lead, zinc, cadmium, mercury, arsenic and chromium） in the sediments from Dagu Dainage Canal at the Bohai Bay during four seasons in 2012 - 2013 are selected, and Water Quality Pollution Index （API） is applied to evaluate water quality indices, aiming for the systematic evaluation of the water quality of Dagu Dainage Canal. The results showed that four stations of D3, D6, D7and D9 for S2 had the type Ⅱand Ⅲ of water; others had the type Ⅰ ; the total level of TOC, TPH, Cu, Pb, Zn, Cd, Hg, As and Cr were type Ⅰ, Ⅳ, Ⅱ, Ⅴ, Ⅱ, Ⅴ, Ⅲ, Vand Ⅴ. Water Quality Pollution Index （API） was 3.28, which illustrated Dagu Dainage Canal was in the state of contamination and the degree of pollution exceeded the standard functional areas. 展开更多

The paper reports quality analysis and evaluation at 6 - 10/0.4 kV low-voltage distribution grids in Uzbekistan. Power quality frequently does not correspond to the rated value which is largely due to unbalanced phase loading in grids and which also results in increased power loss. The study of the asymmetrical operating modes of the rural distribution networks of 0.4 kV was conducted in three steps: measurement, calculations and analysis of relevant data;providing practical guidelines and finally, implementing instruments to normalize grid operation. Measuring was conducted using certified instrumentation analyzer “MALIKA” designed by authors. The study and analysis of additional power losses as the function of indicators of asymmetrical features of voltage and current in operating 0.4 kV grids reveals that, quality of electric power at grids under investigation, merely does not meet the requirements of the Interstate Standard. 展开更多
