MDRPI, a peculiar subtype of pressure injuries (PI), result from the pression exerted by devices (or their fixation systems) applied for diagnostic and therapeutic purposes. MDRPI represent a serious problem for patients and healthcare systems. Understanding potential risk factors is an important step in implementing effective interventions. Methods: In this study, we will perform a systematic review;if possible, also a meta-analysis will be performed. The review will follow the preferred reporting items for systematic reviews and meta-analyses (PRISMA) reporting guidelines for systematic reviews. A rigorous literature search will be conducted both in electronic databases (Medline/PubMed, Embase, CINAHL, Web of Science, Scopus, Cochrane Library) to identify studies published since 2000 and in gray literature for unpublished studies. Pairs of researchers will identify relevant evidence, extract data, and assess risk of bias independently in each eligible study. Factors associated with the occurrence of MDRPI are considered the primary outcome. Secondary outcomes are prevalence and incidence of MDRPI, length of hospital stay, infections, and death. The evidence will be synthesized using the GRADE methodology. Results: Results are not currently available as this is a protocol for a systematic review. Conclusions: This systematic review will identify evidence on risk factors for developing MDRPI. We are confident that the results of this review will help to improve clinical practice and guide future research.展开更多

文摘The scientific assessment of ecosystem ser-vice value(ESV)plays a critical role in regional ecologi-cal protection and management,rational land use planning,and the establishment of ecological security barriers.The ecosystem service value of the Northeast Forest Belt from 2005 to 2020 was assessed,focusing on spatial–temporal changes and the driving forces behind these dynamics.Using multi-source data,the equivalent factor method,and geo-graphic detectors,we analyzed natural and socio-economic factors affecting the region.which was crucial for effective ecological conservation and land-use planning.Enhanced the effectiveness of policy formulation and land use plan-ning.The results show that the ESV of the Northeast Forest Belt exhibits an overall increasing trend from 2005 to 2020,with forests and wetlands contributing the most.However,there are significant differences between forest belts.Driven by natural and socio-economic factors,the ESV of forest belts in Heilongjiang and Jilin provinces showed significant growth.In contrast,the ESV of Forest Belts in Liaoning and Inner Mongolia of China remains relatively stable,but the spatial differentiation within these regions is characterized by significant clustering of high-value and low-value areas.Furthermore,climate regulation and hydrological regulation services were identified as the most important ecological functions in the Northeast Forest Belt,contributing greatly to regional ecological stability and human well-being.The ESV in the Northeast Forest Belt is improved during the study period,but the stability of the ecosystem is still chal-lenged by the dual impacts of natural and socio-economic factors.To further optimize regional land use planning and ecological protection policies,it is recommended to prior-itize the conservation of high-ESV areas,enhance ecological restoration efforts for wetlands and forests,and reasonably control the spatial layout of urban expansion and agricul-tural development.Additionally,this study highlights the importance of tailored ecological compensation policies and strategic land-use planning to balance environmental protec-tion and economic growth.

文摘BACKGROUND:Sepsis may increase the risk of long-term cardiovascular outcomes.This study aims to investigate association between sepsis survivorship and cardiovascular outcomes and to identify risk factors.METHODS:We conducted a comprehensive systematic search of MEDLINE,EMBASE,the Cochrane Library,Wanfang,and CNKI from database inception through May 2025,without language restrictions.The primary outcome was a composite of myocardial infarction,stroke,congestive heart failure,or cardiovascular death.To evaluate the association between sepsis survivors and cardiovascular outcomes,we calculated cumulative incidence rates and hazard ratios(HRs)with corresponding 95%confi dence intervals(95%CIs).RESULTS:Twenty-fi ve observational studies comprising 7,525,271 participants were included.The pooled cumulative incidence of major cardiovascular events was 9.0%(95%CI:6.1%-11.9%),myocardial infarction 2.4%(95%CI:1.6%-3.1%),stroke 4.9%(95%CI:3.8%-6.1%),and congestive heart failure 8.6%(95%CI:4.6%-12.6%).Compared with non-sepsis controls,sepsis survivors had a signifi cantly higher risk of major cardiovascular events(HR:1.54;95%CI:1.32-1.79),myocardial infarction(HR:1.41;95%CI:1.29-1.54),stroke(HR:1.45;95%CI:1.32-1.60),and congestive heart failure(HR:1.51;95%CI:1.46-1.56).Risk factors associated with increased cardiovascular events in sepsis survivors included age≤45 years,male,hyperlipidemia,and multiple comorbidities.CONCLUSION:Adult sepsis survivors may face significantly increased risks of long-term cardiovascular outcomes.Both common cardiovascular risk factors and sepsis-related pathophysiological changes contribute to this association.
文摘Objective: To identify the principal factors associated with the occurrence and development of medical device-related pressure injuries (MDRPI) in adults admitted to hospitals. MDRPI, a peculiar subtype of pressure injuries (PI), result from the pression exerted by devices (or their fixation systems) applied for diagnostic and therapeutic purposes. MDRPI represent a serious problem for patients and healthcare systems. Understanding potential risk factors is an important step in implementing effective interventions. Methods: In this study, we will perform a systematic review;if possible, also a meta-analysis will be performed. The review will follow the preferred reporting items for systematic reviews and meta-analyses (PRISMA) reporting guidelines for systematic reviews. A rigorous literature search will be conducted both in electronic databases (Medline/PubMed, Embase, CINAHL, Web of Science, Scopus, Cochrane Library) to identify studies published since 2000 and in gray literature for unpublished studies. Pairs of researchers will identify relevant evidence, extract data, and assess risk of bias independently in each eligible study. Factors associated with the occurrence of MDRPI are considered the primary outcome. Secondary outcomes are prevalence and incidence of MDRPI, length of hospital stay, infections, and death. The evidence will be synthesized using the GRADE methodology. Results: Results are not currently available as this is a protocol for a systematic review. Conclusions: This systematic review will identify evidence on risk factors for developing MDRPI. We are confident that the results of this review will help to improve clinical practice and guide future research.
文摘With the accelerated pace of population aging in China,the number of patients suffering from myocardial infarction(MI)is increasing annually.During disease progression,patients are at significantly higher risk of developing severe negative emotions,and emerging evidence suggests that post-traumatic stress disorder(PTSD)is significantly associated with cardiovascular disease,which seriously affects patients’quality of life.Objective:The aim of this study was to comprehensively assess the prevalence and influencing factors of PTSD in MI patients through systematic review and Meta-analysis.Methods:A computerized search of PubMed,the Cochrane Library,Embase,Web of Science,PsycINFO,China Knowledge Network(CNKI),WanFang Data,VIP,and China Biomedical Literature Database(CBM)was conducted to collect longitudinal studies,case-control studies,and cross-sectional studies related to PTSD prevalence rates and influencing factors in MI patients published up to August 1,2024.Literature screening,data extraction and quality assessment were done independently by two researchers and Meta-analysis was done using Stata 16.0 software.This study has been registered on the PROSPERO platform,registration number:CRD42024577243.Results:A total of 16 papers were included,with a total sample size of 3,768 cases involving 8 influencing factors.The results of the Meta-analysis showed that the prevalence of PTSD in patients with MI was 20.4%(95%CI=15.0–26.5%).Female(OR=3.12,95%CI=1.97–4.97,P<0.001),high neuroticism score(OR=2.21,95%CI=1.20–4.07,P=0.011),and high intrusive rumination score(OR=2.95,95%CI=1.50–5.83,P=0.002)were the risk factors for PTSD in MI patients.While age(OR=1.01,95%CI=0.98–1.04,P=0.440),education level(OR=0.55,95%CI=0.07–4.48,P=0.574),social support rating scale(OR=0.81,95%CI=0.52–1.26,P=0.346),Killip cardiac function classification(OR=2.29,95%CI=0.91–5.80,P=0.080)and creatine kinase isoenzyme(OR=1.03,95%CI=0.99–1.05,P=0.124)were not associated with the development of PTSD in MI patients.Conclusion:The prevalence of PTSD was higher in patients with MI.The prevalence varied by evaluation tool and study area.Risk factors were multifactorial,including general factors(female)and overall assessment(high neuroticism score,high invasive rumination score).Therefore,early intervention and proper de-escalation of PTSD symptoms in patients with MI by medical staff are needed in clinical practice to reduce the risk of PTSD.

文摘Agricultural land development is a pivotal strategy for addressing the global food security crisis.Barren grassland,especially those in mountainous regions,constitutes critical areas where cultivation can substantially enhance land resources.This study highlights the necessity for a precise correlation between land development initiatives and constraints in order to optimize efficiency and enhance the effectiveness of such projects,with the core being the seamless integration of land development engineering and techniques to eliminate agricultural constraints.This study employs a systems engineering approach to classify improvement factors into mobile and fixed categories,elucidating the integration methods of constraint factors.Adhering to the Wooden Barrel Principle,these constraints were rigorously analyzed based on soil quality,land topography,water availability,and agricultural infrastructure.An innovative method of engineering type combination is proposed,which effectively explains the correlation between natural factors combination,project type combination,and target factors combination.It provides a convenient way for the selection of barren grassland development projects and lays a foundation for land planning,development project establishment,program selection,engineering design,and budget preparation.Taking Tang County of China as an example,it is divided into 19 factor improvement areas,a quick reference table of engineering types is established,and 14 main types of engineering combinations are obtained,which lays a foundation for the application of theoretical framework in practice.

文摘Damped acoustic systems have a limited quality factor due to intrinsic loss.By introducing gain elements,a method to enhance the quality factor of damped systems is proposed based on the concept of bound states in the continuum(BICs).The acoustic model under study is a two-port waveguide system installed with two side Helmholtz resonators connected by a coupling tube.Based on the temporal coupled-mode theory,a Hamiltonian matrix with both intrinsic and radiation losses is used to characterize the resonance behavior of the coupled resonators.To achieve a high quality factor,acoustic gain is introduced to compensate the intrinsic loss,leading the Hamiltonian parameters toward a quasi-BIC condition.Numerical simulation demonstrates a gain-assisted and quasi-BIC-supported extremely high quality factor in damped acoustic systems.The concept is further utilized to design a sensor model for particle size detection.The enhanced sensing performance due to high quality factors is numerically demonstrated.The findings suggest potential applications in acoustic sensing and detection devices.

文摘Myeloblastosis(MYB)transcription factors(TFs)are evolutionarily conserved regulatory proteins that are crucial for plantgrowth,development,secondarymetabolism,andstress adaptation.Recent studieshavehighlighted their crucial role in coordinating growth–defense trade-offs through transcriptional regulation of key biosynthetic and stress-response genes.Despite extensive functional characterization in model plants such as Arabidopsis thaliana,systematically evaluating the broader functional landscape of MYB TFs across diverse species and contexts remains necessary.This systematic review integrates results from 24 peer-reviewed studies sourced from Scopus and Web of Science,focusing on the functional diversity of MYB TFs,particularly in relation to abiotic stress tolerance,metabolic regulation,and plant developmental processes.Advances in genomic technologies,such as transcriptomics,genome editing,and comparative phylogenetics,have considerably enhanced our understanding of MYB-mediated regulatory mechanisms.These tools have facilitated the identification and functional characterization of MYB genes across model and non-model plant species.Key findings underscore the multifaceted roles of MYB TFs in enhancing stress resilience,modulating anthocyanin and flavonoid biosynthesis,and contributing to yield-related traits,thereby highlighting their potential applications in crop improvement and sustainable agriculture.However,critical gaps exist in understanding MYB interactions within complex regulatory networks,particularly in underrepresented plant species and ecological contexts.This review consolidates current knowledge as well as identifies research gaps and proposes future directions to advance the understanding and application of MYB TFs.The insights derived from this study underscore their transformative potential in addressing global challenges including food security and climate resilience through innovative agricultural practices.

文摘Purpose:This umbrella systematic review(SR) of SRs and meta-analysis seeks to comprehensively synthesize existing literature to identify and consolidate the diverse range of risk factors contributing to running-related injuries(RRIs).Methods:Systematic searches were conducted on June 28,2023,across Web of Science,SPORTDiscus,Scopus,PubMed,and Cochrane Library.We included SRs,whether accompanied by meta-analyses or not,that focused on investigating risk factors for RRIs within observational studies.The methodological quality of the SRs was evaluated using the Assessing the Methodological Quality of Systematic Reviews Ⅱ.To assess the extent of overlap across reviews,the corrected covered area metric was calculated.Results:From 1509 records retrieved,13 SRs were included.The degree of overlap between SRs was low(4%),and quality varied from critically low(n=8) to low(n=5).Two hundred seven outcomes assessed in 148 primary studies were identified as being associated with the occurrence of RRIs.The effect sizes of the associations for which risk measures were reported(n=131) were classified as large(n=30,23%),medium(n=38,29%),small(n=48,37%) or no effect(n=15,11%).Running/training characteristics,health and lifestyle factors,along with morphological and biomechanical aspects,exhibit large effect sizes in increasing the risk for RRIs.Conclusion:Drawing from the outcomes of the low-quality SRs and associations with large effect sizes,our findings indicate that running/training characteristics and health and lifestyle factors,as well as morphological and biomechanical aspects,are all implicated in elevating the risk of RRIs,emphasizing the multifactorial basis of injury incidence in running.Given the low quality and heterogeneity of SR,individual findings warrant cautious interpretation.
