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

文摘Background:Cyperi Rhizoma,derived from Cyperus rotundus L.,is a widely used medicinal herb in traditional Chinese medicine(TCM),with Shandong Province recognized as its geo-authentic habitat.However,the quality of Cyperi Rhizoma varies significantly across different regions,potentially influencing its therapeutic efficacy.This study investigates the influence of geographic origin on the chemical composition and overall quality of Cyperi Rhizoma.Methods:A comprehensive approach,including traditional quality assessment,GC-MS(g as c hromatography-m ass s pectrometry),RP-HPLC(r everse p hase h igh-p erformance l iquid c hromatography),and FT-IR(f ourier t ransform i nfrared s pectroscopy)techniques,was employed to analyze Cyperi Rhizoma samples from Shandong Province.These methods examined the physical appearance,chemical profile,and content variations,particularly focusing onα-cyperone.Results:Traditional quality assessments revealed noticeable differences in the external characteristics of the samples.GC-MS analysis identified a variety of unique chemical constituents,while RP-HPLC and FT-IR showed significant variations inα-cyperone content,with higher levels found in Shandong samples.Conclusion:These results demonstrate that geographic origin is a critical determinant of Cyperi Rhizoma quality,with Shandong specimens exhibiting superiorα-cyperone levels and characteristic phytochemical profiles.This validates the geo-authenticity concept in TCM and provides actionable data for developing evidence-based quality standards,suggesting that provenance should be prioritized in medicinal material selection and pharmacopeial specifications.
文摘To investigate the efficacy of a structured continuous nursing intervention program on clinical outcomes,self-efficacy,and sleep quality in patients diagnosed with aplastic anemia(AA).Methods:This study was a single-center,parallel-group,randomized controlled trial.A total of 64 patients with AA,treated at our hospital’s hematology department from May 2022 to May 2025,were enrolled.Participants were randomly allocated in a 1:1 ratio to either the control group(n=32),receiving routine nursing care,or the intervention group(n=32),receiving a six-month continuous nursing intervention program in addition to routine care.The intervention program consisted of structured health education,individualized psychological support,regular telephone follow-ups,and a 24/7 online communication platform.The primary outcome was the change in the Pittsburgh Sleep Quality Index(PSQI)score from baseline to six months.Secondary outcomes included hematological parameters(hemoglobin[Hb],absolute neutrophil count[ANC],platelet count[PLT]),incidence of adverse events(infections,bleeding episodes),quality of life(assessed by the Functional Assessment of Cancer Therapy–Anemia[FACT-An]),and self-efficacy(assessed by the General Self-Efficacy Scale[GSE]).Statistical analyses were performed using independent t-tests,and chi-square tests or Fisher’s exact tests as appropriate.Results:A total of 55 patients(28 in the intervention group and 27 in the control group)completed the study.At baseline,there were no statistically significant differences in demographic data,clinical characteristics,or outcome measures between the two groups(p>0.05).After six months,the mean PSQI score in the intervention group was significantly lower than that in the control group(7.12±2.05 vs.13.49±2.88;t=−13.450;p<0.001).The intervention group also demonstrated a significantly lower incidence of infections(4/28,14.29%vs.10/27,37.04%;p=0.048)and bleeding episodes requiring intervention(3/28,10.71%vs.9/27,33.33%;p=0.042).Furthermore,patients in the intervention group reported significantly higher scores on the FACT-An(125.70±10.31 vs.109.44±12.10;t=7.934;p<0.001)and the GSE scale(29.82±4.11 vs.23.51±4.80;t=7.311;p<0.001).While hematological parameters showed a trend toward improvement in the intervention group,the differences were not statistically significant compared to the control group(p>0.05).Conclusion:The implementation of a structured continuous nursing intervention program can significantly improve sleep quality,reduce the incidence of complications,and enhance quality of life and self-efficacy in patients with aplastic anemia.This evidence-based model of care should be considered for integration into standard clinical practice for the long-term management of this patient population.

文摘The high labor demand during rice seedling cultivation and transplantation poses a significant challenge in advancing machine-transplanted rice cultivation.This problem may be solved by increasing the seeding rate during seedling production while reducing the number of seedling trays.This study conducted field experiments from 2021 to 2022,using transplanting seedling ages of 10 and 15 days to explore the effects of 250,300,and 350 g/tray on the seedling quality,mechanical transplantation quality,yields,and economic benefits of rice.The commonly used combination of 150 g/tray with a 20-day seedling age in rice production was used as CK.The cultivation of seedlings under a high seeding rate and short seedling age significantly affected seedling characteristics,but there was no significant difference in seedling vitality compared to CK.The minimum number of rice trays used in the experiment was observed in the treatment of 350-10(300 g/tray and 10-day seedling age),only 152-155 trays ha^(-1),resulting in a 62%reduction in the number of trays needed.By increasing the seeding rate of rice,missed holes during mechanical transplantation decreased by 2.8 to 4%.The treatment of 300-15(300 g/tray and 15-day seedling age)achieved the highest yields and economic gains.These results indicated that using crop straw boards can reduce the application of seedling trays.On that basis,rice yields can be increased by raising the seeding rate and shortening the seedling age of rice without compromising seedling quality.

文摘Laser directed energy deposition(LDED)is an emerging branch of metal-based additive manufacturing(AM)processes,offering unprecedented capabilities for high-performance fabrication with complex geometries and near-net shapes.This technology is gathering increasing attention from industries such as biomedical,automotive,and aerospace.However,achieving consistent part quality and desired material properties is challenging due to intricate processing parameters and potential process defects such as dynamic melt-pool behavior and localized heat accumulation.This paper reviews recent advances in on-line quality control,focusing on in-situ measurement and closed-loop control for efficient assurance of LDED-fabricated parts.The quality principles,encompassing accuracy and material performance,are summarized to lay a foundation for understanding the mechanisms of quality defects and influencing factors.This review explores and thoroughly compares advancements in indirect process measurements,such as optical,thermal,and acoustic monitoring with direct quality measurements,including laser-line scanning and operando synchrotron X-ray imaging.Depending on the sensing techniques,this paper highlights a hierarchical control strategy for adaptive parameter regulation on intra-layer and inter-layer scales.The requirements and performance of various state-of-the-art controllers are critically compared to indicate their suitable applications.The importance of machine learning in detecting process anomalies and predicting build quality based on sensory signals is also outlined.Future directions are proposed towards adaptive,automated,and intelligent quality control,with a focus on multi-modal monitoring,physics-informed neural networks for interpretable analysis,and multi-objective control applications.
文摘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.

文摘This study explores whether the current external quality assessment(EQA)level and acceptable bias for basic semen analysis in China are clinically useful.We collected data of semen EQA from Andrology laboratories in the Hunan Province(China)in 2022 and searched for data in the published literature from January2000 to December 2023 in China.On the basis of these data,we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics.We compared these findings with quality specifications based on biological variation from optimal,desirable,and minimum levels of bias to seek a unified and more suitable semen EQAbias evaluation standard for China's national conditions.Different sources of semen quality control material exhibited considerable variation in acceptable biases among laboratories,ranging from 8.2%to 56.9%.A total of 50.0% of the laboratories met the minimum quality specifications for progressive motility(PR),whereas 100.0%and 75.0%of laboratories met only the minimum quality specifications for sperm concentration and total motility(nonprogressive[NP]+PR),respectively.The Z value for sperm concentration and PR+NP was equivalent to the desirable performance specification,whereas the Z value for PR was equivalent only to the minimum performance specification.This study highlights the feasibility of operating external quality assessment schemes for basic semen analysis using quality specifications based on biological variation.These specifications should be unified among external quality control(EQC)centers based on biological variation.
文摘Objective:To evaluate and compare the quality of life(QoL)in patients with multidrug-resistant(MDR-TB)and drug-sensitive(DS-TB)as well as to investigate factors associated with QoL among MDR-TB patients in real-world scenarios at the Haji Hospital,Surabaya.Methods:We conducted a case-control study from June to December 2024.MDR-TB and DS-TB patients were classified into case and control groups,respectively.We used the World Health Organization’s Quality of Life Brief(WHOQOL-BREF)instrument and Patient Health Questionnaire-9(PHQ-9)to assess QoL and depression levels,respectively.Multivariate analysis was used to analyze factors associated with QoL of patients with MDR-TB.Results:Forty-one patients with MDR-TB and 43 with DS-TB were enrolled in the study.A mean score for all domains(physical,psychological,social relationship,environmental)and total mean score of WHOQOL-BREF was significantly lower in MDR-TB than those with DS-TB(P<0.05).The prevalence of depression and the mean score of PHQ-9 were significantly higher in MDR-TB than in DS-TB(P<0.05).PHQ-9 negatively correlates with the WHOQOL-BREF score(r=-0.502,P<0.05)among MDR-TB patients.MDR-TB patients with depression were significantly associated with low QoL in the physical(OR 3.611;95%CI 2.393-6.951;P=0.029),psychological(OR 1.672;95%CI 1.179-5.941;P=0.021),social relationship(OR 2.586;95%CI 1.611-2.909;P=0.014),and environmental domains(OR 1.926;95%CI 1.047-2.147;P=0.048).Conclusions:MDR-TB patients had worse QoL than DS-TB.Those with depression were associated with low QoL.Strategies that identify and tackle alterations in the QoL for MDR-TB patients are necessary during TB treatment.

文摘Knee osteoarthritis(KOA),characterized by heterogeneous arthritic manifestations and complex peripheral joint disorder,is one of the leading causes of disability worldwide,which has become a high burden due to the multifactorial nature and the deficiency of available disease-modifying treatments.The application of mesenchymal stem/stromal cells(MSCs)as therapeutic drugs has provided novel treatment options for diverse degenerative and chronic diseases including KOA.However,the complexity and specificity of the“live”cells have posed challenges for MSC-based drug development and the concomitant scale-up preparation from laboratory to industrialization.For instance,despite the considerable progress in ex vivo cell culture technology for fulfilling the robust development of drug conversion and clinical trials,yet significant challenges remain in obtaining regulatory approvals.Thus,there’s an urgent need for the research and development of MSC drugs for KOA.In this review,we provide alternative solution strategies for the preparation of MSC drugs on the basis of the principle of quality by design,including designing the cell production processes,quality control,and clinical applications.In detail,we mainly focus on the quality by design method for MSC manufacturing in standard cell-culturing factories for the treatment of KOA by using the Quality Target Product Profile as a starting point to determine potential critical quality attributes and to establish relationships between critical material attributes and critical process parameters.Collectively,this review aims to meet product performance and robust process design,and should help to reduce the gap between compliant products and the production of compliant good manufacturing practice.
