    神经血管耦合(NVC)是脑血流量(CBF)的扰动,以满足各种水平的神经活动引起的不同代谢需求。NVC可以通过经颅多普勒超声(TCD)进行评估,使用任务激活协议,但由于研究之间的方法异质性很大,阻碍交叉研究比较。因此,这篇综述旨在总结和比较基于TCD的健康NVC评估的可用方法。Medline(Ovid),Scopus,WebofScience,EMBASE(Ovid)和CINAHL使用预定义的搜索策略进行搜索(PROSPERO:CRD42019153228),生成6006篇文章。纳入的研究包含基于TCD的健康成人NVC评估。使用清单评估研究质量,研究结果是以叙述方式综合的。76项研究(2697名参与者)符合审查标准。所使用的参与者位置存在显著的异质性(例如,坐着vs仰卧),在TCD设备中,和血管被声波照射(如中部,后部,和大脑前动脉)。较大,更重要的是,基于TCD的NVC响应通常包括就座位置,基线持续时间>一分钟,外来光线控制,和实施先前验证的协议。此外,互补,组合位置,血管超声和刺激型方案与更显著的NVC结果相关.这里有详细的建议,但是需要对患者人群进行进一步调查,用于进一步优化基于TCD的NVC评估。
    Neurovascular coupling (NVC) is the perturbation of cerebral blood flow (CBF) to meet varying metabolic demands induced by various levels of neural activity. NVC may be assessed by Transcranial Doppler ultrasonography (TCD), using task activation protocols, but with significant methodological heterogeneity between studies, hindering cross-study comparisons. Therefore, this review aimed to summarise and compare available methods for TCD-based healthy NVC assessments. Medline (Ovid), Scopus, Web of Science, EMBASE (Ovid) and CINAHL were searched using a predefined search strategy (PROSPERO: CRD42019153228), generating 6006 articles. Included studies contained TCD-based assessments of NVC in healthy adults. Study quality was assessed using a checklist, and findings were synthesised narratively. 76 studies (2697 participants) met the review criteria. There was significant heterogeneity in the participant position used (e.g., seated vs supine), in TCD equipment, and vessel insonated (e.g. middle, posterior, and anterior cerebral arteries). Larger, more significant, TCD-based NVC responses typically included a seated position, baseline durations >one-minute, extraneous light control, and implementation of previously validated protocols. In addition, complementary, combined position, vessel insonated and stimulation type protocols were associated with more significant NVC results. Recommendations are detailed here, but further investigation is required in patient populations, for further optimisation of TCD-based NVC assessments.

    随着人们年龄的增长,认知功能和大脑结构自然下降。然而,老年人的脑功能与认知之间的关系既不简单也不统一。相反,它是复杂的,受多种因素影响,并且可能因人而异。Reserve,补偿,和维持机制可能有助于解释为什么一些老年人可以保持高水平的表现,而另一些人则挣扎。这些机制经常被研究,涉及对衰老影响特别敏感的记忆和执行功能。然而,语言能力也会受到年龄的影响,随着生产流畅性的变化。需要进一步研究大脑变化对语言能力的影响,以了解衰老的动态和模式,尤其是成功的衰老。我们先前在词汇访问和老化检索(LARA)模型中对语言生成和词汇访问/检索的几个补偿性配置文件进行了建模。在本论文中,我们提出了LARA模型的扩展版本,称为LARA-连通性(LARA-C),结合了最近关于大脑连通性的证据。最后,我们讨论了可能影响随着年龄增长而实施的策略的因素。LARA-C模型可以作为一个框架来理解个人表现,并为可能的个性化干预打开途径。
    As people age, there is a natural decline in cognitive functioning and brain structure. However, the relationship between brain function and cognition in older adults is neither straightforward nor uniform. Instead, it is complex, influenced by multiple factors, and can vary considerably from one person to another. Reserve, compensation, and maintenance mechanisms may help explain why some older adults can maintain high levels of performance while others struggle. These mechanisms are often studied concerning memory and executive functions that are particularly sensitive to the effects of aging. However, language abilities can also be affected by age, with changes in production fluency. The impact of brain changes on language abilities needs to be further investigated to understand the dynamics and patterns of aging, especially successful aging. We previously modeled several compensatory profiles of language production and lexical access/retrieval in aging within the Lexical Access and Retrieval in Aging (LARA) model. In the present paper, we propose an extended version of the LARA model, called LARA-Connectivity (LARA-C), incorporating recent evidence on brain connectivity. Finally, we discuss factors that may influence the strategies implemented with aging. The LARA-C model can serve as a framework to understand individual performance and open avenues for possible personalized interventions.

    芦笋属约300种,包括A.Curilus,A.filicinus,A.反应,和A.officinalisL.该属中特别著名的成员是芦笋L.,也被称为“蔬菜之王”。食用A.officinalis对健康饮食做出了出色的贡献。现代研究表明,它具有利尿作用,促进排便;它还显示出高水平的基本营养素,包括维生素,氨基酸和矿物盐。此外,它富含纤维。芦笋含有大量的叶酸(10个煮熟的芽提供225微克,或每日需求量的近50%)和维生素C(10煮熟的芽提供25毫克)。本综述描述了有关A的各个部分的健康特性的最新文献。特别关注它的矛。它基于电子数据库中确定的研究,包括PubMed,ScienceDirect,WebofKnowledge,SciFinder,WebofScience,和SCOPUS。数据表明,各部分的巴草,尤其是长矛,含有许多生物活性化合物。然而,虽然从A.officinalis中分离出的提取物和化合物,尤其是皂苷,似乎具有各种生物学特性和有利于健康的潜力,这些观察结果仅限于体外和动物体内模型。
    The genus Asparagus comprises about 300 species, including A. curilus, A. filicinus, A. reacemosus, and A. officinalis L. A particularly well-known member of the genus is Asparagus officinalis L., also known as \"the king of vegetables\". Consuming A. officinalis makes an excellent contribution to a healthy diet. Modern studies have shown it to have a diuretic effect and promote defecation; it also demonstrates high levels of basic nutrients, including vitamins, amino acids and mineral salts. Moreover, it is rich in fiber. Asparagus contains large amounts of folic acid (10 cooked shoots provide 225 micrograms, or almost 50% of the daily requirement) and vitamin C (10 cooked shoots provide 25 mg). The present review describes the current literature concerning the pro-health properties of various parts of A. officinalis L., with a particular focus on its spears. It is based on studies identified in electronic databases, including PubMed, ScienceDirect, Web of Knowledge, Sci Finder, Web of Science, and SCOPUS. The data indicate that the various parts of A. officinalis, especially the spears, contain many bioactive compounds. However, although the extracts and chemical compounds isolated from A. officinalis, especially saponins, appear to have various biological properties and pro-health potential, these observations are limited to in vitro and animal in vivo models.

    健康预期寿命(HLE)的概念融合了预期寿命和健康状况的概念,提供了一个有价值的指标来评估生命的长度和质量。本文旨在通过对定义和衡量HLE,以及相关已发表的研究描述。遵循系统审查和Meta分析扩展的首选报告项目,用于范围审查声明,从2020年1月至2023年4月,研究了两个英语语言文学数据库。通过提取研究区域的数据,分析了与HLE相关的实证研究的结果,设计,人口,健康状态测量工具,以及使用HLE指标的研究结果。当前的分析包括48项实证研究。研究人员在这个语料库中发现了11个独特的HLE指标,每个人都集中在一个特定的方面。此外,分析揭示了18种评估健康状况的不同工具,每个人对健康状态的定义都不同,测量的尺寸,以及使用的数据类别。因此,融合全球健康概念,HLE指标,评估健康状态的方法,和应用研究演示对于统一的HLE指标体系创建至关重要。
    The concept of healthy life expectancy (HLE) integrates the ideas of life expectancy and health status, providing a valuable metric to evaluate both the length and quality of life. This paper seeks to aid policymakers in creating an inclusive HLE indicator system through a systematic review of methodologies for defining and measuring HLE, along with relevant published studies\' descriptions. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement, two English language literature databases were researched from January 2020 to April 2023. Findings from empirical HLE-related studies were analyzed by extracting data on the study area, design, population, healthy state measurement tools, and results of studies using HLE indicators. The current analysis encompassed 48 empirical studies. Researchers discerned 11 unique HLE indicators within this corpus, each concentrating on a particular aspect. Furthermore, the analysis revealed 18 diverse instruments for evaluating health statuses, each varying in its definition of a healthy state, dimensions of measurement, and the categories of data employed. Therefore, merging global health concepts, HLE indicators, methodologies for assessing healthy states, and applied research demonstrations are essential for a consolidated HLE indicator system creation.

    这项研究的目的是探讨水果消费之间的关系,蔬菜和坚持地中海饮食与儿童哮喘的发展和严重程度。在过去的二十年中,进行了系统的文献检索和结果综合。共分析了45项研究,纳入了392,797名儿童。坚持地中海型饮食与哮喘结局呈负相关(OR:0.71,95%CI:0.54,0.88)。关于水果,蔬菜消费,研究发现水果或蔬菜摄入量增加与哮喘之间存在显著负相关(OR:0.82,95%CI:0.77,0.86;0.84,95%CI:0.77,0.91).水果和蔬菜的综合消费也与所有哮喘结局呈负相关(OR:0.65,95%CI:0.49,0.78)。异质性水平为中高(30%-97%)。本综述和荟萃分析显示,坚持地中海饮食或富含水果和蔬菜的健康饮食与儿童哮喘的发生呈负相关趋势,但确定性较低。
    The objective of this study was to explore the relationship between the consumption of fruits, vegetables and adherence to the Mediterranean diet with childhood asthma development and severity. A systematic literature search and synthesis of the results was performed throughout the last two decades. A total of 45 studies were analysed and 392,797 children were included. Greater adherence to a Mediterranean type of diet was inversely associated with asthmatic outcomes (OR:0.71,95% CI:0.54,0.88). Regarding fruits, vegetables consumption, a significant inverse association between increased fruits or vegetable intake and asthma was found (OR:0.82,95% CI:0.77,0.86; 0.84,95% CI:0.77,0.91, respectively). Fruits and vegetables consumption combined was also inversely related to all asthmatic outcomes (OR:0.65,95% CI:0.49,0.78). The level of heterogeneity was moderate-to-high (30%-97%). The present review and meta-analysis show a trend to an inverse association between adherence to the Mediterranean diet or a healthy diet rich in fruits and vegetables and the occurrence of childhood asthma but with a low level of certainty.

    由于全球3/4人口的脂肪过多或不足,了解脂肪组织(AT)的功能和功能障碍变得越来越重要。AT是能量代谢的关键器官,最近,注意力一直集中在白色AT上,尤其是它的线粒体,因为文献证据将它们的功能与肥胖联系起来。这篇叙述性综述概述了人类白色AT的线粒体功能。首先,值得注意的是,两个主要的AT仓库,皮下AT(SCAT)和内脏AT(VAT),表现出线粒体密度和活性的差异。值得注意的是,与scAT相比,vAT倾向于具有更高的线粒体活性。随后,研究揭示了线粒体活性和体重指数(BMI)之间的负相关,表明肥胖与较低的线粒体功能有关。虽然运动对AT线粒体的影响仍不确定,饮食干预对AT线粒体有不同的影响。这种变异性有望调节AT线粒体活性。总之,AT线粒体对健康结果产生重大影响,并可能受到肥胖和饮食干预等因素的影响。了解这些反应的潜在机制可以为管理与AT和整体健康相关的疾病提供潜在的见解。
    As ¾ of the global population either have excess or insufficient fat, it has become increasingly critical to understand the functions and dysfunctions of adipose tissue (AT). AT serves as a key organ in energy metabolism, and recently, attention has been focused on white AT, particularly its mitochondria, as the literature evidence links their functions to adiposity. This narrative review provides an overview of mitochondrial functionality in human white AT. Firstly, it is noteworthy that the two primary AT depots, subcutaneous AT (scAT) and visceral AT (vAT), exhibit differences in mitochondrial density and activity. Notably, vAT tends to have a higher mitochondrial activity compared to scAT. Subsequently, studies have unveiled a negative correlation between mitochondrial activity and body mass index (BMI), indicating that obesity is associated with a lower mitochondrial function. While the impact of exercise on AT mitochondria remains uncertain, dietary interventions have demonstrated varying effects on AT mitochondria. This variability holds promise for the modulation of AT mitochondrial activity. In summary, AT mitochondria exert a significant influence on health outcomes and can be influenced by factors such as obesity and dietary interventions. Understanding the mechanisms underlying these responses can offer potential insights into managing conditions related to AT and overall health.

    BACKGROUND: The utility of procalcitonin to identify obstetric sepsis is unknown.
    OBJECTIVE: To calculate the mean (range) procalcitonin in pregnancy among healthy women not in labor (group 1), healthy women in labor (group 2), and women with preterm prelabor rupture of membranes (PPROM) without clinical chorioamnionitis (group 3).
    METHODS: NLM PubMed, Elsevier Embase, and Wiley Cochrane Central Register of Controlled Trials from inception to February 21, 2022.
    METHODS: Ten or more pregnant women with procalcitonin reported at more than 20 weeks of pregnancy, with information on labor, PPROM, and infection. Exclusions were major medical comorbidities.
    METHODS: Each abstract and full-text review was independently reviewed by the same two authors. Quality was reviewed using the Newcastle-Ottawa Scale. A meta-analysis was performed using a random effects model.
    RESULTS: The systematic review included 25 studies: 10 (40%) of good quality and 15 (60%) of poor quality. The meta-analysis included 21 studies. Mean procalcitonin in group 1 was 0.092 ng/mL (range 0.036-0.049 ng/mL), in group 2 it was 0.130 ng/mL (range 0.049-0.259 ng/mL), and in group 3 it was 0.345 ng/mL (range 0.005-1.292 ng/mL).
    CONCLUSIONS: Among healthy pregnant women not in labor, procalcitonin levels are comparable to those in non-pregnant adults and may be useful in identifying infection. Procalcitonin levels in other groups overlap abnormal values of procalcitonin in non-pregnant adults, and may not discriminate infection among women in labor or with obstetric comorbidities.

    Fats and oils in food give them flavor and texture while promoting satiety. Despite the recommendation to consume predominantly unsaturated lipid sources, its liquid behavior at room temperature makes many industrial applications impossible. Oleogel is a relatively new technology applied as a total or partial replacement for conventional fats directly related to cardiovascular diseases (CVD) and inflammatory processes. Some of the complications in developing oleogels for the food industry are finding structuring agents Generally Recognized as Safe (GRAS), viable economically, and that do not compromise the oleogel palatability; thus, many studies have shown the different possibilities of applications of oleogel in food products. This review presents applied oleogels in foods and recent proposals to circumvent some disadvantages, as reaching consumer demand for healthier products using an easy-to-use and low-cost material can be intriguing for the food industry.

    背景:前交叉韧带(ACL)断裂是膝关节最常见的损伤之一。女性ACL破裂的损伤率高于男性。有争议地讨论了这种性别差异的各种指标。
    目的:对成年女性和男性受试者的表面肌电图(EMG)值进行比较的文献进行系统回顾,以了解膝关节稳定肌肉的神经肌肉激活是否存在差异。
    方法:本系统评价由系统评价和荟萃分析(PRISMA)指南的首选报告项目指导和指导。用表面肌电图测量检查性别特异性差异的研究(积分,均方根,平均值,时间和振幅的分析)通过从数据库PubMed中搜索来检索膝盖稳定肌肉,CINAHL,Embase,中央和SPORTDiscus。纳入研究的偏倚风险与国家心脏评估,肺和血液研究所(NHLBI)研究质量评估工具。对相关结果进行了综合。
    结果:对462名健康参与者进行了15项研究,233名女性(平均年龄21.9(±2.29)岁)和299名男性(平均年龄22.6(±2.43)岁),包括在系统审查中。研究的方法学质量大多被评为“一般”(40%)。在女性中发现了股外侧肌和股内侧肌的明显较高的活动,在三项研究中。两项研究发现,女性股二头肌和半腱肌的神经肌肉活动显着降低。所有其他纳入的研究均未发现显着差异,甚至报告了矛盾的结果。
    结论:有争议的发现不允许对性别特异性神经肌肉激活的问题做出结论。具有更高的统计能力和更均匀的方法程序(任务和数据标准化)的进一步研究可以提供对神经肌肉激活中可能存在的性别特异性差异的见解。这种系统的回顾可以帮助改进未来研究的方法设计,以获得更有效的结论。

    BACKGROUND: The rupture of the anterior cruciate ligament (ACL) is one of the most common injuries of the knee. Women have a higher injury rate for ACL ruptures than men. Various indicators for this sex-specific difference are controversially discussed.
    OBJECTIVE: A systematic review of the literature that compares surface electromyography (EMG) values of adult female and male subjects to find out if there is a difference in neuromuscular activation of the knee stabilizing muscles.
    METHODS: This systematic review has been guided and informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies which examined sex-specific differences with surface EMG measurements (integral, root mean squares, mean values, analysis of time and amplitude) of the knee stabilizing muscles were retrieved via searches from the databases PubMed, CINAHL, Embase, CENTRAL and SPORTDiscus. The risk of bias of included studies was assessed with the National Heart, Lung and Blood Institute (NHLBI) study quality assessment tool. A synthesis of results was performed for relevant outcomes.
    RESULTS: Fifteen studies with 462 healthy participants, 233 women (mean age 21.9 (± 2.29) years) and 299 men (mean age 22.6 (± 2.43) years), were included in the systematic review. The methodological quality of the studies was mostly rated \"fair\" (40%). A significantly higher activity of the muscles vastus lateralis and vastus medialis was found in females, in three studies. Two studies found significantly lower neuromuscular activity in the muscles biceps femoris and semitendinosus in females. All other included studies found no significant differences or reported even contradicting results.
    CONCLUSIONS: The controversial findings do not allow for a concluding answer to the question of a sex-specific neuromuscular activation. Further research with higher statistical power and a more homogeneous methodical procedure (tasks and data normalisation) of the included studies may provide insight into possibly existing sex-specific differences in neuromuscular activation. This systematic review could help to improve the methodical design of future studies to get a more valid conclusion of the issue.
