Objective: The triglyceride-glucose index and estimated glucose disposal rate serve as notable surrogate markers of insulin resistance, demonstrating established links to cardio-cerebrovascular disease. However, their combined prognostic value in predicting cardio-cerebrovascular disease outcomes remains unexplored. The current investigation examined the interaction between the TyG (triglyceride-glucose index) index and eGDR (estimated glucose disposal rate) concerning the danger of cardiovascular disease within a clinical population.

Methods: This investigation employed data sourced from the China Health and Retirement Longitudinal Study (CHARLS). The median TyG index and eGDR scores were used to stratify the participants into 4 categories: low TyG/high eGDR, high TyG/high eGDR, low TyG/low eGDR, and high TyG/low eGDR. Clinical characteristics across groups were systematically compared. Cox proportional hazards regression models evaluated the distinct and interconnected associations of the TyG index and eGDR with the risk of cardio-cerebrovascular disease, with multiplicative and additive interaction effects subsequently assessed through formal interaction analysis.

Results: The final study cohort comprised 7,330 participants, with 1,336 individuals (18.2%) developing cardio-cerebrovascular disease during the 9-year follow-up. Stratification using median thresholds (TyG: 8.59; eGDR: 10.55 mg/kg/min) yielded four groups: low TyG/high eGDR (n = 2,991), high TyG/high eGDR (n = 1,375), low TyG/low eGDR (n = 1,372), and high TyG/low eGDR (n = 2,292). Multivariable-adjusted Cox regression analyses revealed markedly increased risks of cardio-cerebrovascular disease among the various exposure groups when contrasted with the low TyG/high eGDR reference: high TyG/high eGDR (HR: 1.31, 95%CI: 1.10-1.57, p< 0.05), low TyG/low eGDR (HR: 1.54, 95%CI: 1.29-1.84, p< 0.05), and high TyG/low eGDR (HR: 1.55, 95%CI: 1.31-1.82, p< 0.05). Interaction analysis revealed significant multiplicative effects between TyG and eGDR but no evidence of additive interaction.

Conclusion: The TyG index and eGDR demonstrate independent associations with cardio-cerebrovascular disease risk, while their combined assessment reveals synergistic predictive capacity. Combined assessment of the two allows for further accurate stratification of the population based on insulin resistance and improved prediction of cardio-cerebrovascular disease.

目的:甘油三酯-葡萄糖指数和估计的葡萄糖处理率作为胰岛素抵抗的显著替代指标,证明了与心脑血管疾病的建立联系。然而,它们在预测心脑血管疾病预后方面的综合预后价值仍未得到探索。目前的研究检查了TyG(甘油三酯-葡萄糖指数)指数和eGDR(估计葡萄糖处理率)之间的相互作用,与临床人群中心血管疾病的危险有关。方法:本研究数据来源于中国健康与退休纵向研究(CHARLS)。使用中位数TyG指数和eGDR评分将参与者分为4类:低TyG/高eGDR,高TyG/高eGDR,低TyG/低eGDR,高TyG/低eGDR。系统比较各组临床特征。Cox比例风险回归模型评估了TyG指数和eGDR与心脑血管疾病风险之间独特且相互关联的关系,随后通过正式相互作用分析评估了乘法和加性相互作用效应。结果:最终的研究队列包括7330名参与者,其中1336人(18.2%)在9年的随访期间发生心脑血管疾病。使用中位数阈值(TyG: 8.59; eGDR: 10.55 mg/kg/min)分层得到四组:低TyG/高eGDR (n = 2,991),高TyG/高eGDR (n = 1,375),低TyG/低eGDR (n = 1,372)和高TyG/低eGDR (n = 2,292)。多变量校正Cox回归分析显示,与低TyG/高eGDR对照相比,不同暴露组的心脑血管疾病风险显著增加;高TyG/高eGDR对照(HR: 1.31, 95%CI: 1.10-1.57, p)结论:TyG指数和eGDR与心脑血管疾病风险独立相关,两者联合评估具有协同预测能力。两者的综合评估允许基于胰岛素抵抗和改进的心脑血管疾病预测进一步准确的人群分层。

<p><strong>Background and aim: </strong>Cardiovascular diseases (CVDs) represent a growing public-health challenge in India, where nearly one in four deaths is CVD-related. Accurate risk stratification underpins targeted prevention, yet laboratory-dependent tools are often impractical in resource-limited settings. The World Health Organization (WHO) and GLOBORISK initiatives both offer non-laboratory-based 10-year CVD risk algorithms alongside their laboratory-based counterparts.

Participants with prior CVD were excluded. Ten-year CVD risk was calculated using sex-specific WHO (South Asia) and India-calibrated GLOBORISK models, both laboratory-based (age, sex, smoking, systolic blood pressure, diabetes, total cholesterol) and non-laboratory-based (age, sex, smoking, systolic blood pressure, BMI) algorithms. Categorical agreement was quantified via percentage agreement and quadratic weighted kappa (κ); continuous agreement by Bland-Altman analysis. We also evaluated linear associations between each risk score (categorical and continuous) and three sub-clinical atherosclerosis markers: carotid intima-media thickness (CIMT), pulse-wave velocity (PWV), and augmentation index (AIx), through sex-stratified multi-level linear regression with random intercept at the household level, adjusting for multiple testing (p < 0.01).</p><p><strong>Results: </strong>Median WHO-CVD-risk was 6.0% (IQR 4% - 9%) in men and 3.0% (2% - 4%) in women for both lab and non-lab models; median GLOBORISK-CVD-risk was 12.0% (9% - 16%) for lab-model vs. 15.0% (10% - 16%) for non-lab-model in men and 5.0% (3% - 9%) for lab-model vs. 5.0% (3% - 9%) for non-lab-model in women. Categorical agreement was substantial to almost perfect: WHO κ = 0.82 (overall), GLOBORISK κ = 0.72. Bland-Altman analyses demonstrated mean differences <1% between lab- and non-lab-based scores, though non-lab models underestimated risk by 4.2% in diabetics and 1.2% in participants with total cholesterol ≥200 mg/dL.

背景和目的:心血管疾病在印度是一项日益严重的公共卫生挑战,在印度,近四分之一的死亡与心血管疾病有关。准确的风险分层是有针对性预防的基础,但在资源有限的情况下,依赖实验室的工具往往是不切实际的。世界卫生组织(世卫组织)和GLOBORISK倡议除了提供基于实验室的10年心血管疾病风险算法外,还提供非实验室的10年心血管疾病风险算法。我们的目的是比较实验室和非实验室的WHO和GLOBORISK心血管疾病风险评分,评估其一致性,并检查印度农村队列中亚临床动脉粥样硬化的关系。材料和方法:我们对来自安得拉邦儿童和父母研究(APCAPS)第三波(2010-12年)的2465名40-74岁的成年人(1184名男性,1281名女性)进行了横断面分析。既往有心血管疾病的参与者被排除在外。使用性别特异性WHO(南亚)和印度校准的GLOBORISK模型计算十年心血管疾病风险,这两种模型均基于实验室(年龄、性别、吸烟、收缩压、糖尿病、总胆固醇)和非实验室(年龄、性别、吸烟、收缩压、BMI)算法。分类一致性通过一致性百分比和二次加权kappa (κ)来量化;Bland-Altman分析的连续一致。我们还评估了每个风险评分(分类和连续)与三个亚临床动脉粥样硬化标志物之间的线性关联:颈动脉内膜-中膜厚度(CIMT),脉搏波速度(PWV)和增强指数(AIx),通过性别分层的多层级线性回归,在家庭水平上随机截取,调整多重测试(p结果:实验室和非实验室模型中,男性who - cvd风险中位数为6.0% (IQR为4% - 9%),女性为3.0% (2% - 4%);实验室模型患者globorisk - cvd风险中位数为12.0%(9% - 16%),男性为15.0%(10% - 16%),女性为5.0%(3% - 9%),实验室模型患者为5.0%(3% - 9%)。分类一致性基本达到近乎完美:WHO κ = 0.82(总体),GLOBORISK κ = 0.72。结论:非基于实验室的WHO和GLOBORISK心血管疾病风险评分与基于实验室的模型总体上一致,并且与印度农村的亚临床动脉粥样硬化密切相关。然而,对高危亚组(糖尿病、高胆固醇血症)的适度低估值得谨慎解释。这些发现支持了在资源受限环境下进行非实验室风险评估的可行性,同时强调了在大规模实施之前对硬心血管结果进行前瞻性验证的必要性。

Introduction: Patients with significant liver fibrosis (SF) are likely to progress to advanced chronic liver disease (ACLD). Therefore, liver-directed therapy is indicated. The European Association for the Study of the Liver-2024 (EASL) recommends annual screening of patients with diabetes for SF/ACLD using the FIB-4 score, followed by vibration-controlled transient elastography (VCTE) in patients with FIB-4 ≥ 1.3 in ≤65-year-olds and ≥2.0 in > 65-year-olds. Because VCTE is not freely available in resource-limited settings, we revised the EASL algorithm to prioritise referrals for VCTE in such settings and validated it in an external cohort.

Methods: We conducted a cross-sectional study of adults with type 2 diabetes (T2DM) and ultrasonographic evidence of steatotic liver disease (SDL) attending three outpatient medical clinics in the Gampaha District, Sri Lanka. FIB-4 scores were calculated, and those with scores ≥1.3 underwent VCTE. SF was defined as liver stiffness measure (LSM) ≥ 8.0 kPa. Factors significantly associated with SF/ACLD were identified using multiple logistic regression (LR). We then developed a new criterion for VCTE referral and compared the number of referrals for VCTE when using the new criterion-based algorithm with the EASL algorithm. We validated the new criterion-based algorithm in an external cohort of 372 patients with MASLD.

Results: We studied 363 patients, and 128 had an FIB-4 score of≥1.3. Of them,121 underwent VCTE, and 76 had an LSM ≥ 8.0 kPa. On multivariable LR, VCTE-diagnosed SF/ACLD was independently associated with diabetes of ≥ 5 years duration (OR 3.8, p = 0.035), micro/macrovascular complications (OR 19.4, p = 0.016), and BMI of ≥ 25 kg/m2(OR 6.2, p = 0.003). We revised the VCTE referral criterion as "patients having EASL FIB-4 criterion plus one or more of the three other factors: diabetes of ≥ 5 years duration, presence of micro/macrovascular complications or BMI≥25 kg/m2,". The number of VCTE referrals indicated using the EASL algorithm was 96, compared to 83 with the new criterion, resulting in a 13.5% reduction. In the external validation cohort, the new algorithm reduced the number requiring VCTE referral by 15.5%.

Conclusions: Adopting the new criterion for VCTE referral in patients with MASLD appears more cost-effective for detecting SF/ACLD in low-resource settings in South Asia.

重度肝纤维化(SF)患者有可能发展为晚期慢性肝病(ACLD)。因此,建议肝导治疗。欧洲肝脏研究协会-2024 (EASL)建议每年使用FIB-4评分对糖尿病患者进行SF/ACLD筛查,然后对FIB-4≥1.3(≤65岁)和≥2.0(≥65岁)的患者进行振动控制瞬时弹性成像(VCTE)。由于VCTE在资源有限的情况下不能免费获得,我们修改了EASL算法,以便在这种情况下优先考虑VCTE的转诊,并在外部队列中进行验证。方法:我们对在斯里兰卡Gampaha区的三个门诊诊所就诊的2型糖尿病(T2DM)和脂肪变性肝病(SDL)的成人患者进行了横断面研究。计算FIB-4评分,评分≥1.3分者行VCTE。SF定义为肝刚度测量值(LSM)≥8.0 kPa。使用多元逻辑回归(LR)确定与SF/ACLD显著相关的因素。然后,我们制定了一个新的VCTE转诊标准,并比较了使用基于新标准的算法与EASL算法时VCTE的转诊数量。我们在372例MASLD患者的外部队列中验证了新的基于标准的算法。结果:我们研究了363例患者,其中128例FIB-4评分≥1.3。其中VCTE 121例,LSM≥8.0 kPa 76例。在多变量LR上,vcte诊断的SF/ACLD与持续时间≥5年的糖尿病(OR 3.8, p = 0.035)、微血管/大血管并发症(OR 19.4, p = 0.016)和BMI≥25 kg/m2(OR 6.2, p = 0.003)独立相关。我们将VCTE的转诊标准修改为“具有EASL FIB-4标准的患者加上其他三个因素中的一个或多个:糖尿病持续时间≥5年,存在微/大血管并发症或BMI≥25 kg/m2”。使用EASL算法的VCTE转诊数量为96例,而新标准为83例,减少了13.5%。在外部验证队列中,新算法将需要VCTE转诊的数量减少了15.5%。结论:在南亚低资源环境中,在MASLD患者中采用VCTE转诊的新标准对于检测SF/ACLD更具成本效益。

Acute kidney injury (AKI) remains a major clinical challenge due to its high morbidity and mortality, with ischemia-reperfusion injury (IRI) as one of its primary causes. Severe IRI-associated AKI (IRI-AKI) can progress to irreversible renal failure, yet no effective therapies are currently available. Ferroptosis, an iron-dependent regulated cell death, has recently been implicated in the pathogenesis of IRI-AKI. Moreover, IL-22 may alleviate AKI by modulating the ferroptosis process through regulation of the P62-Keap1-Nrf2 signaling axis. In this study, we examined the protective role of the immune cytokine interleukin-22 (IL-22) in IRI-AKI and its mechanistic association with ferroptosis. Using a murine IRI model and an HK-2 cell hypoxia/reoxygenation system, we systematically assessed the impact of IL-22 treatment. IL-22 administration significantly enhanced renal function, reduced histological injury, and limited both reactive oxygen species accumulation and ferroptotic cell death. Further mechanistic studies demonstrated that IL-22 suppresses ferroptosis in vitro through an Nrf2-dependent mechanism and is associated with activation of the P62-Keap1-Nrf2 signaling pathway. These findings offer experimental evidence supporting IL-22 as a potential therapy for IRI-AKI and highlight ferroptosis modulation as a promising therapeutic strategy.

急性肾损伤(AKI)由于其高发病率和死亡率一直是一个重大的临床挑战,而缺血再灌注损伤(IRI)是其主要原因之一。严重的iri相关性AKI (IRI-AKI)可发展为不可逆的肾功能衰竭,但目前尚无有效的治疗方法。铁下垂是一种铁依赖性调节的细胞死亡,最近被认为与IRI-AKI的发病机制有关。此外,IL-22可能通过调节P62-Keap1-Nrf2信号轴调节铁下垂过程,从而减轻AKI。在这项研究中,我们研究了免疫细胞因子白细胞介素-22 (IL-22)在IRI-AKI中的保护作用及其与铁ptosis的机制关联。通过小鼠IRI模型和HK-2细胞缺氧/再氧化系统,我们系统地评估了IL-22治疗的影响。给药IL-22可显著增强肾功能,减少组织学损伤,限制活性氧积累和铁致细胞死亡。进一步的机制研究表明,IL-22在体外通过nrf2依赖的机制抑制铁凋亡,并与P62-Keap1-Nrf2信号通路的激活有关。这些发现提供了实验证据,支持IL-22作为IRI-AKI的潜在治疗方法,并强调了铁下垂调节是一种有前景的治疗策略。

Sepsis is a life-threatening state of disseminated infection, and treatment requires knowledge of the organism responsible. The gold standard for sepsis diagnosis is blood culture, which requires days of growth. Next-generation sequencing has been proposed as an alternative; however, existing methods may lack sensitivity. In this work, we explore the idea of genomic quasi-G-primes, which are short DNA sequences specific to a single species within a group of relevant species. We first validated the genomic quasi-G-prime classification in controlled Staphylococcus aureus sequencing experiments, and then applied the same approach to blood-derived sequencing data from septic and healthy patients, where genomic quasi-G-prime profiles distinguished disease states. Our method is highly space-efficient, permitting fast classification on modest hardware and enabling it to outperform existing taxonomic classification approaches in this task.

败血症是一种危及生命的播散性感染状态,治疗需要了解致病微生物。诊断败血症的黄金标准是血液培养,这需要数天的生长时间。新一代测序被提议作为一种替代方案;然而,现有的方法可能缺乏敏感性。在这项工作中,我们探讨了基因组准g '的概念,这是一组相关物种中特定于单个物种的短DNA序列。我们首先在对照金黄色葡萄球菌测序实验中验证了基因组准g -prime分类,然后将相同的方法应用于脓毒症和健康患者的血液来源测序数据,其中基因组准g -prime图谱可区分疾病状态。我们的方法具有很高的空间效率,允许在适度的硬件上进行快速分类,并使其在此任务中优于现有的分类学分类方法。

Virtual Reality Development Centres (VRDCs) represent a recent extension of Assessment Center (AC) methodology, yet empirical evidence on their validity and their relationship to established evaluation systems remains limited. This study addresses this gap by examining how VRDC assessments-grounded in immersive, real-time behavioral observation-converge with traditional 270-degree evaluations and self-assessments across five managerial competencies. Using a sample of 64 mid-level managers who completed 16 VRDC sessions and parallel 270-degree evaluations, we tested three hypotheses concerning convergent validity and unique diagnostic value. VRDC demonstrated strong inter-rater reliability (rwg = .82-.95; ICC(2) =.76-.92) and showed significant alignment with 270-degree ratings for managing people and tasks, goal orientation, and change management, but not for decision-making or cooperation. Self-assessments correlated with VRDC only for cooperation, and negatively for managing people and tasks, revealing consistent self-perception biases. Across all competencies, VRDC provided diagnostic insights not captured by self-report, supporting its added theoretical value. The findings contribute to theory by clarifying the distinct construct domains captured by immersive behavioral simulations versus retrospective, perception-based evaluations. We argue that VRDC should be conceptualized not merely as a technological enhancement, but as a methodological bridge that integrates AC logic with multi-source frameworks. Practically, VRDC offers organizations a reliable and context-sensitive tool for assessing crisis-relevant competencies, complementing-but not replacing-traditional evaluation methods. The study advances the theoretical understanding of VR-based assessment and informs the development of multimethod competency assessment systems.

虚拟现实开发中心(vrdc)代表了评估中心(AC)方法的最新扩展,但关于其有效性及其与已建立的评估系统的关系的经验证据仍然有限。本研究通过研究VRDC评估(基于沉浸式实时行为观察)如何与传统的270度评估和五种管理能力的自我评估相融合,解决了这一差距。我们以64名中层管理者为样本,他们完成了16次VRDC会议,并进行了平行的270度评估,我们测试了关于收敛效度和独特诊断价值的三个假设。VRDC表现出很强的评分者间信度(rwg = 0.82 - 0.95; ICC(2) = 0.76 - 0.92),并且在人员和任务管理、目标导向和变革管理方面与270度评分显著一致,但在决策或合作方面则不一致。自我评价与VRDC仅在合作方面呈负相关,在人员管理和任务管理方面呈负相关,显示出一致的自我认知偏差。在所有能力中,VRDC提供了自我报告无法捕捉的诊断见解,支持了其附加的理论价值。研究结果通过澄清沉浸式行为模拟与回顾性、基于感知的评估所捕获的不同结构域,为理论做出了贡献。我们认为,VRDC不仅应该作为一种技术增强,而且应该作为将交流逻辑与多源框架集成在一起的方法桥梁。实际上,VRDC为组织提供了一种可靠且对环境敏感的工具,用于评估与危机相关的能力,是对传统评估方法的补充,而不是取代。该研究促进了基于虚拟现实的评估的理论认识,并为多方法能力评估系统的开发提供了指导。

Psychometric properties of the Adult Primary Care Assessment Tool Short form (PCAT-S) among high-risk patients in Australian general practice. 成人初级保健评估工具短表格(PCAT-S)在澳大利亚全科医生高危患者中的心理测量特性。
IF 2.6 3区 综合性期刊 Q1 MULTIDISCIPLINARY SCIENCES Pub Date : 2026-02-06 eCollection Date: 2026-01-01 DOI: 10.1371/journal.pone.0341250

Introduction: The Primary Care Assessment Tool (PCAT) is designed to assess a patient's experience with primary care across various core and ancillary domains, including First contact - Utilization, First contact - Access, Ongoing Care, Coordination, Comprehensiveness (services provided), Family-centeredness, Community Orientation, and Cultural Competence. This study examined the psychometric properties of the Adult Primary Care Assessment Tool Short Form (PCAT-S) in the Australian general practice setting.

Method: Data included 715 participants from the EQuIP-GP study, a cluster randomized controlled trial (RCT) conducted with adults aged 18-65 years with a chronic illness or aged over 65 years, from 34 general practices across Australia. For each subscale we assessed internal consistency using Cronbach's alpha. Factor structure of the PCAT-S instrument was assessed through confirmatory and exploratory factor analysis, using three samples with different methods for handling 'don't know/can't remember' responses.

Results: The findings were mixed. Specifically, the subscales related to First Contact - Utilization, Ongoing Care and Comprehensiveness, demonstrated satisfactory internal consistency. However, the remaining subscales showed weak internal consistency. Confirmatory factor analysis indicated potential model misspecification, while exploratory factor analysis generally supported the hypothesized factor structure, albeit with some observed deviations.

Conclusions: The findings indicate the PCAT-S shows promise as an instrument to evaluate primary care experiences in Australia. However, the observed variability in internal consistency, along with issues identified in confirmatory and exploratory factor analyses, highlight the need for further validation and refinement in this population. Further research is required to address the identified limitations and enhance the tool's applicability within the Australian general practice context.

简介:初级保健评估工具(PCAT)旨在评估患者在各种核心和辅助领域的初级保健体验,包括首次接触-利用,首次接触-获取,持续护理,协调,综合性(提供的服务),以家庭为中心,社区导向和文化能力。本研究考察了澳大利亚全科医生设置的成人初级保健评估工具短表格(PCAT-S)的心理测量特性。方法:数据包括来自EQuIP-GP研究的715名参与者,这是一项随机对照试验(RCT),研究对象是来自澳大利亚34家全科医院的18-65岁患有慢性疾病或65岁以上的成年人。对于每个子量表,我们使用Cronbach's alpha评估内部一致性。采用三种不同处理“不知道/记不起来”反应的方法,通过验证性和探索性因子分析对PCAT-S仪器的因子结构进行评估。结果:调查结果喜忧参半。具体而言,与第一次接触-利用、持续关怀和综合性相关的子量表显示出令人满意的内部一致性。但其余分量表的内部一致性较弱。验证性因子分析显示潜在的模型错误,而探索性因子分析总体上支持假设的因素结构,尽管存在一些观察到的偏差。结论:研究结果表明,PCAT-S显示了作为评估澳大利亚初级保健经验的工具的希望。然而,观察到的内部一致性的可变性,以及在验证性和探索性因素分析中发现的问题,突出了在该人群中进一步验证和改进的必要性。需要进一步的研究来解决已确定的局限性,并提高该工具在澳大利亚全科实践背景下的适用性。

Introduction: This review focuses on the need to identify the lung function assessment tools used for young EC users. The objectives are to examine the current and emerging methods used in assessing lung function among young EC users, besides identifying the alterations in lung function following EC exposure measured by those tools.

Methodology: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 flow checklist. Six databases (Web of Science, PubMed, Scopus, Taylor & Francis, SAGE, and ScienceDirect) were searched in April 2025 for original articles published between 2016 and 2025. Quality appraisal of the eligible articles was conducted using the Joanna Briggs Institute (JBI) Critical Appraisal Tools. Findings were synthesized using Narrative analysis.

Results: A total of 7 studies were included. Spirometry was used in all included studies; however, it is unable to detect subclinical lung alterations, as observed through ventilation-perfusion (V/Q) MRI and fractional exhaled nitric oxide (FeNO). Acute exposure to EC results in a decrease of FEV₁, FVC, PEF, and MEF₇₅ spirometric parameters, as well as reducing FeNO levels, while concurrently increasing exhaled breath temperature (EBT). Besides, an increase in V/Q mismatch and heterogeneity in ventilation is observed, with a reduction in perfusion heterogeneity. Chronic EC exposure causes a reduction in FEV1, PEF, FEV1/FVC, and FEF25-75%, besides an increment of Carboxyhaemoglobin (HbCO) level. The assessment of the lung function post-EVALI in association with EC cessation revealed lung function improvement and increased diffusing capacity of the lung for carbon monoxide (DLCO).

Conclusions: Spirometry remains the first-line tool for assessing the lung function of young EC users; however, it often misses early lung dysfunction. Emerging methods (FeNO, DLCO, EBT, MRI, HbCO) increasingly complement this limitation. Tailoring multimodal assessment to exposure context, alongside screening and monitoring programs, may assist in early disease detection and prevent long-term respiratory effects.

引言:本综述的重点是确定用于年轻EC使用者的肺功能评估工具的必要性。目的是检查目前和新兴的用于评估年轻电子烟使用者肺功能的方法,除了确定这些工具测量的电子烟暴露后肺功能的变化。方法:本系统评价根据系统评价和荟萃分析首选报告项目(PRISMA) 2020流程清单进行。我们在2025年4月检索了六个数据库(Web of Science、PubMed、Scopus、Taylor & Francis、SAGE和ScienceDirect),查找2016年至2025年间发表的原创文章。使用乔安娜布里格斯研究所(JBI)关键评估工具对符合条件的文章进行质量评估。运用叙事分析法对研究结果进行综合。结果:共纳入7项研究。所有纳入的研究均使用肺活量测定法;然而,它无法通过通气灌注(V/Q) MRI和呼气一氧化氮分数(FeNO)观察到亚临床肺改变。急性暴露于EC会导致FEV₁,FVC, PEF和MEF₇₅呼吸参数降低,并降低FeNO水平,同时增加呼出温度(EBT)。此外,观察到通气的V/Q错配和异质性增加,灌注异质性降低。慢性EC暴露会导致FEV1、PEF、FEV1/FVC和FEF25-75%的降低,此外还会增加羧血红蛋白(HbCO)水平。evali后与停用EC相关的肺功能评估显示肺功能改善和肺一氧化碳弥散能力(DLCO)增加。结论:肺活量测定法仍然是评估年轻电子烟使用者肺功能的一线工具;然而,它经常忽略早期肺功能障碍。新兴方法(FeNO, DLCO, EBT, MRI, HbCO)越来越多地补充了这一局限性。根据暴露情况量身定制多模式评估,以及筛查和监测方案,可能有助于早期发现疾病并预防长期呼吸系统影响。

Extracts from Cordyceps cicadae and Hericium erinaceus promote the neurite outgrowth of retinal ganglion cells. 冬虫夏草和猴头草提取物促进视网膜神经节细胞的神经突生长。

The regenerative capacity of mammalian RGC neurites after damage, such as glaucoma, is limited. Numerous studies have utilized herbal extracts to promote neural regeneration and exert neuroprotective effects in the hope of mitigating glaucoma. In the present study, we investigated the effect of extracts from the cicada fungus (Cordyceps cicadae) and the Lion's mane mushroom (Hericium erinaceus) on neurite outgrowth of retinal explants and isolated RGCs. We also examined whether these extracts affect the number of apoptotic cells and neurite outgrowth activity of RGCs. The results showed that an aqueous extract of Cordyceps cicadae, an ethanol extract of Hericium erinaceus, and the purified compound Erinacine Sare able to promote neurite outgrowth in retinal explants. Given its role as a key bioactive compound, Erinacine S was further investigated on isolated RGCs, where it also significantly enhanced neurite outgrowth, demonstrating a direct effect on RGC regeneration. In addition, these extracts have no significant drawbacks in terms of cell apoptosis and RGC neurite outgrowth activity at specific concentrations. The present study thus demonstrates that while excessively high concentrations of these extracts may inhibit neurite growth, at moderate concentrations some extracts from Cordyceps cicadae and Hericium erinaceus have the potential of promoting neurite regeneration in the mammalian retina. Further research targeting the molecular mechanisms behind these effects may shed light on their potential application as a medicine or nutraceutical for facilitating neural regeneration.

在青光眼等损伤后,哺乳动物RGC神经突的再生能力是有限的。许多研究利用草药提取物促进神经再生,发挥神经保护作用,以期减轻青光眼。在本研究中,我们研究了蝉菌(Cordyceps cicadae)和狮鬃菌(Hericium erinaceus)提取物对视网膜外植体和离体RGCs神经突生长的影响。我们还研究了这些提取物是否影响RGCs的凋亡细胞数量和神经突生长活性。结果表明,蝉虫草水提物、猴头草乙醇提物和纯化后的复方猴头草提取物均能促进视网膜外植体神经突的生长。鉴于其作为一种关键的生物活性化合物的作用,Erinacine S在分离的RGC上进行了进一步的研究,在那里它也显著地促进了神经突起的生长,证明了对RGC再生的直接影响。此外,在特定浓度下,这些提取物在细胞凋亡和RGC神经突起生长活性方面没有明显的缺陷。因此,本研究表明,虽然这些提取物的浓度过高可能会抑制神经突的生长,但在中等浓度下,一些冬虫夏草和猴头草提取物具有促进哺乳动物视网膜神经突再生的潜力。针对这些作用背后的分子机制的进一步研究可能会揭示它们作为促进神经再生的药物或营养品的潜在应用。

Having to control multiple tasks in parallel poses challenges for humans and artificial agents alike. In artificial intelligence, specific forms of reinforcement learning (RL), most notably hierarchical and model-based RL, have shown promising results in scenarios where tasks or skills need to be switched adaptively. However, RL agents still encounter difficulties when faced with serial multitasking that involves switching control between continuously running subtasks, such as changing the radio station while driving in traffic. Inspired by human cognitive processes, we hypothesize that maintaining a sense of control is a key mechanism facilitating such task-switching decisions. We propose a mathematical formulation of a situational sense of control that consists of two components: an evaluative indicator of the predictability of action outcomes and a predictive indicator of a need for control in individual subtasks. We integrate this model of a sense of control into a hierarchical RL agent and evaluate its performance in a Collect Asteroids game environment, in which one must alternate between navigating two spaceships to collect as many asteroids as possible. Comparing RL agents with and without a sense of control, as well as with human participants, shows that equipping RL agents with a sense of control results in significant performance improvements. Our findings indicate that agents equipped with a sense of control prioritize more complex tasks, exhibit increased switching behavior, and make switches at strategically optimal times, leading to superior overall performance. The incorporation of cognitive mechanisms, inspired by human behavior, into RL agents thus appears to yield considerable enhancements in performance when acting in complex and dynamic environments.

必须同时控制多个任务对人类和人工智能体都提出了挑战。在人工智能中,特定形式的强化学习(RL),尤其是分层和基于模型的强化学习,在需要自适应切换任务或技能的场景中显示出有希望的结果。然而,RL代理在面对串行多任务时仍然会遇到困难,这涉及到在连续运行的子任务之间切换控制,例如在交通中驾驶时更换广播电台。受人类认知过程的启发,我们假设保持控制感是促进这种任务转换决策的关键机制。我们提出了一个情景控制感的数学公式,它由两个组成部分组成:行动结果可预测性的评估指标和单个子任务控制需求的预测指标。我们将这种控制感模型整合到层级强化学习代理中,并评估其在《Collect Asteroids》游戏环境中的表现,即玩家必须在驾驶两艘宇宙飞船以收集尽可能多的小行星之间进行选择。比较有控制感和没有控制感的强化学习代理,以及与人类参与者的对比,表明给强化学习代理配备控制感会显著提高性能。我们的研究结果表明,具有控制感的智能体优先处理更复杂的任务,表现出更多的切换行为,并在战略最佳时间进行切换,从而导致卓越的整体表现。因此,将受人类行为启发的认知机制整合到强化学习代理中,在复杂和动态环境中行动时,似乎会产生相当大的性能增强。
