    商业过度开发和气候变化可以改变海洋生物的生理和行为,尽管对这种变化的种内表型反应可能因环境而异,物种,和压力源的严重程度。在生活节奏综合症(POLS)假设下,行为,生理学,和生活史特征是联系在一起的,因此,受针对生物生物学任何方面的选择的影响。然而,这些联系在热带海洋鱼类中得到了充分的研究,需要进一步的工作来更好地了解渔业和气候变化对野生种群的影响。此外,热带地区更依赖渔业;因此,调查应侧重于具有重大社会经济价值的物种,以确保地方一级的利益。本研究旨在通过测量行为(大胆和活动)来满足这一需求,新陈代谢,和游泳表现(使用临界游泳速度[Ucrit]测试)在Eleuthera,巴哈马。我们报告了勇气和活动之间的强烈正相关,这些行为指标的高可重复性,以及与“主动”和“被动”行为类型一致的两个分组。这些行为类型在游泳表现上有很大不同,反应性个体的平均Ucrit高出13.1%。相比之下,在行为类型之间测量的代谢参数没有发现显著差异.这项研究是第一个调查的行为和生理学之间的种内联系,使用Ucrit与行为综合征类型的新颖和生态相关的比较。这些数据表明,如果过度开发并受气候变化的影响,需要进行更多的研究来更好地预测主动/反应性热带鱼的成功。
    Commercial overexploitation and climate change can alter the physiology and behavior of marine organisms, although intraspecific phenotypic responses to such changes can vary greatly depending on the environment, species, and severity of the stressor. Under the pace-of-life syndrome (POLS) hypothesis, behavior, physiology, and life-history traits are linked, and thus, affected by selection targeting any aspect of organismal biology. However, these links are understudied in tropical marine fishes, and further work is needed to better understand the impacts of fisheries and climate change on wild stocks. Moreover, tropical regions have a greater reliance on fisheries; thus investigations should focus on species with substantial socioeconomic value to ensure benefits at the local level. This study aimed to address this need by measuring the behavior (boldness and activity), metabolism, and swimming performance (using a critical swim speed [Ucrit] test) of schoolmaster snapper Lutjanus apodus in Eleuthera, the Bahamas. We report a strong positive correlation between boldness and activity, high repeatability of these behavioral metrics, and two groupings that were consistent with \"proactive\" and \"reactive\" behavioral types. These behavioral types differed significantly in their swimming performance, with reactive individuals having a 13.1% higher mean Ucrit. In contrast, no significant differences were found in the measured metabolic parameters between behavioral types. This study is the first to investigate the intraspecific links between behavior and physiology in a snapper species, using the novel and ecologically relevant comparison of Ucrit with behavioral syndrome types. These data suggest that additional research is needed to better predict the success of proactive/reactive tropical fish if overexploited and as influenced by climate change.

    目的:接受英夫利昔单抗(IFX)治疗的炎症性肠病(IBD)患者通常通过形成抗药物抗体(ADAs)而经历免疫原性反应丧失(LOR)。已知与初始IFX诱导组合使用的免疫调节剂(IMM)减少ADA发展并改善临床结果。我们旨在评估反应性添加IMM对IFX单一疗法患者的影响。
    方法:我们对IBD患者进行了回顾性队列研究和系统评价,并进行了荟萃分析,有或没有临床LOR,有IMM(硫唑嘌呤,6-巯基嘌呤,或甲氨蝶呤)反应性添加(反应性联合疗法;rCT)以对抗升高的ADA并提高IFX水平。使用随机效应模型提取数据用于合并效应大小估计,在IMM启动前后比较了ADA和IFX谷水平。
    结果:我们确定了6例因ADA滴度升高和IFX水平低而接受rCT的患者。中值ADA滴度从506ng/mL(四分位距(IQR)[416-750])降至76.5ng/mL(IQR[25.8-232]),减少85%(p=0.031)。中值IFX波谷从0.4µg/mL(IQR[0.4-0.48])增加到8.25µg/mL(IQR[3.7-9.6]),增加20.6倍(p=0.038)。包括89例患者的7项研究的荟萃分析汇总效应大小显示,ADA滴度降低了87%[95%置信区间(CI)=72-94%],IFX波谷增加6.7倍(95%CI=2.4-18.7),临床缓解抢救率为76%(95%CI=59-93%)。
    结论:这些结果表明,rCT是一种有效的挽救策略,适用于对IFX进行免疫原性LOR以降低ADA滴度的患者,恢复治疗性IFX水平,并重新获得IBD的临床缓解。
    OBJECTIVE: Patients with inflammatory bowel disease (IBD) receiving infliximab (IFX) commonly experience immunogenic loss of response (LOR) by formation of anti-drug antibodies (ADAs). An immunomodulator (IMM) used in combination with initial IFX induction is known to reduce ADA development and improve clinical outcomes. We aimed to assess the impact of reactively adding an IMM to patients on IFX monotherapy.
    METHODS: We conducted a retrospective cohort study and systematic review with meta-analysis of patients with IBD demonstrating immunologic LOR, with or without clinical LOR, that had an IMM (azathioprine, 6-mercaptopurine, or methotrexate) reactively added (reactive combination therapy; rCT) to combat elevated ADAs and raise IFX level. Data were extracted for pooled effect size estimation using random-effects models, and ADA and IFX trough levels were compared pre- and post-IMM initiation.
    RESULTS: We identified 6 patients who received rCT due to rising ADA titers and low IFX levels. Median ADA titer decreased from 506 ng/mL (interquartile range (IQR) [416-750]) to 76.5 ng/mL (IQR [25.8-232]), an 85% decrease (p = 0.031). Median IFX trough increased from 0.4 µg/mL (IQR [0.4-0.48]) to 8.25 µg/mL (IQR [3.7-9.6]), a 20.6-fold increase (p = 0.038). Meta-analysis pooled effect size of 7 studies with 89 patients showed an 87% ADA titer reduction [95% confidence interval (CI) = 72-94%], 6.7-fold increased IFX trough (95% CI = 2.4-18.7), and 76% clinical remission rescue rate (95% CI = 59-93%).
    CONCLUSIONS: These results suggest rCT is a valid rescue strategy in patients with immunogenic LOR to IFX to reduce ADA titers, restore therapeutic IFX levels, and recapture clinical remission of IBD.

    先前的研究表明额叶和边缘大脑区域与侵略相关的结构改变。大多数研究都集中在整体攻击性上,而不是它的亚型,在特定地区而不是网络上。这项研究旨在确定与侵略的反应性和主动性亚型相关的大脑网络和区域。从340名青少年(125F/215M)收集了结构MRI数据,平均年龄为16.29岁(SD=1.20)。通过反应性主动攻击问卷(RPQ)对攻击症状进行索引。Freesurfer用于估计与侵略相关的七个网络和特定网络中的区域的皮质体积(CV)。对低与高反应性和前瞻性RPQ评分的组进行了两个多变量协方差分析(MANCOVA)。在所有7个网络中,我们的反应性侵略MANCOVA在CV[F(14,321)=1.935,p=0.022,ηp2=0.078]中显示出主要影响。打开这个主要效应揭示了右边缘网络(LN)(p=0.029)和时间极(p=0.011)的显着体积差异,反应性较高的攻击组的青少年表现出更高的皮质体积。这些发现与区域/体素特异性分析一致,这些分析在LN内具有相关的非典型结构和反应性攻击。此外,时间极与调节和启动反应性侵略的重要区域高度互连。
    Previous studies show aggression-related structural alterations in frontal and limbic brain regions. Most studies have focused on overall aggression, instead of its subtypes, and on specific regions instead of networks. This study aims to identify both brain networks and regions that are associated with reactive and proactive subtypes of aggression. Structural MRI data were collected from 340 adolescents (125 F/215 M) with a mean age of 16.29 (SD = 1.20). Aggression symptomology was indexed via the Reactive Proactive Aggression Questionnaire (RPQ). Freesurfer was used to estimate Cortical Volume (CV) from seven networks and regions within specific networks associated with aggression. Two multivariate analyses of covariance (MANCOVAs) were conducted on groups for low versus higher reactive and proactive RPQ scores. Our reactive aggression MANCOVA showed a main effect in CV [F(14,321) = 1.935, p = 0.022,ηp2 = 0.078] across all the 7-Networks. Unpacking this main effect revealed significant volumetric differences in the right Limbic Network (LN) (p = 0.029) and the Temporal Pole (p = 0.011), where adolescents in the higher reactive aggression group showed higher cortical volumes. Such findings are consistent with region/voxel-specific analyses that have associated atypical structure within the LN and reactive aggression. Moreover, the temporal pole is highly interconnected with regions important in the regulation and initiation of reactive aggression.

    移动机器人远程呈现系统需要有关环境的信息,任务,并且机器人被呈现给远程定位的用户(操作者),其控制机器人以执行特定任务。在这项研究中,两种交互模式,主动和被动,用户从机器人接收信息的方式不同,在模拟医疗保健环境的实验系统中进行了比较。用户控制着一个移动远程呈现机器人,该机器人交付和接收物品(药物,食物,或饮料),在用户执行次要医疗保健相关任务时,还从模拟患者获得了指标(生命体征)(他们汇编了健康记录,这些记录显示在屏幕上并回答了相关问题)。通过参与者内部研究设计,评估了两种交互模式对整体表现和用户感知的影响,其中50名参与者属于两种不同类型的人群(有或没有技术背景)。效率,有效性,理解,满意,情境意识被定义为客观和主观测量的因变量。主动模式提高了用户性能,与反应模式相比,减少了工作量。然而,一些用户重视在反应模式中体验的增加用户控制的选项。我们,因此,提出了设计建议,以强调将反应模式作为混合模式纳入设计的一些好处。
    Mobile robotic telepresence systems require that information about the environment, the task, and the robot be presented to a remotely located user (operator) who controls the robot for a specific task. In this study, two interaction modes, proactive and reactive, that differ in the way the user receives information from the robot, were compared in an experimental system simulating a healthcare setting. The users controlled a mobile telepresence robot that delivered and received items (medication, food, or drink), and also obtained metrics (vital signs) from a simulated patient while the users performed a secondary healthcare-related task (they compiled health records which were displayed to them on the screen and answered related questions). The effect of the two interaction modes on overall performance and user perception was evaluated through a within-participant study design conducted with 50 participants belonging to two different types of populations (with and without a technological background). Efficiency, effectiveness, understanding, satisfaction, and situation awareness were defined as the dependent variables measured both objectively and subjectively. The proactive mode increased user performance, and understanding of the system and reduced the workload compared to the reactive mode. However, several of the users valued the option of increased user control experienced in the reactive mode. We, therefore, proposed design suggestions to highlight some of the benefits of factoring the reactive mode into the design as a hybrid mode.

    足球教练和从业者通常优先考虑对敏捷性的训练和评估,以发展多方向的速度。尽管在整个童年和青春期都提倡敏捷的重要性,有限的数据证明青春期不同阶段的敏捷性表现。这项研究的目的是研究跨越整个足球学院的青年足球运动员在多方向速度表现方面的差异。共有86名男性初级精英足球运动员自愿参加。收集人体测量数据,除了一系列物理测试的表现数据,包括短跑,跳跃,改变方向,反应时间,和敏捷性。使用来自参数值后验模拟的对数似然性的贝叶斯模型在敏捷性和反应时间以外的所有测试中显示了时间和生物年龄与性能之间的线性或曲线关系。对于敏捷性和反应时间测试,性能得到改善,直到约14岁或估计的峰值高度速度年龄,从而观察到性能发展受阻。我们的结果表明,虽然大多数表现技能随着时间或生物年龄的增加而提高,敏捷性和反应时间的衡量标准可能不会。这些发现支持敏捷性表现是复杂和多方面的概念,引出独特的,挑战物理需求和非线性发展。
    Training and assessment of agility is often prioritised by soccer coaches and practitioners aiming to develop multi-directional speed. Although the importance of agility is advocated throughout childhood and adolescence, limited data evidence agility performance at different stages of adolescence. The purpose of this study was to examine differences in multi-directional speed performance in youth soccer players spanning an entire soccer academy. A total of 86 male junior-elite soccer players volunteered to participate. Anthropometric data were collected, alongside performance data from a battery of physical tests including sprinting, jumping, change of direction, reaction time, and agility. Bayesian models using log-likelihoods from posterior simulations of parameter values displayed linear or curvilinear relationships between both chronological and biological age and performance in all tests other than agility and reaction time. For agility and reaction time tests, performance improved until ~14 years of age or the estimated age of peak height velocity whereby arrested development in performance was observed. Our results demonstrate that while most performance skills improve as chronological or biological age increases, measures of agility and reaction time may not. These findings support the notion that agility performance is complex and multifaceted, eliciting unique, challenging physical demands and non-linear development.

    背景:反应性关节炎和脓毒性关节炎很少在同一关节和患者中同时出现。2019年冠状病毒病后出现的反应性关节炎也极为罕见,到目前为止,报告的病例不到30例。据报道,不常见的病原体如艰难梭菌可引起反应性关节炎,特别是在人白细胞抗原B27阳性的患者中,因此应在诊断算法中考虑。本病例报告的目的是强调辨别和诊断膝盖突然肿胀的患者的困难和预防措施。
    方法:我们报告了一名70岁的高加索男性,近期有冠状病毒疾病史,2019年上呼吸道感染和腹泻以及消除创伤,膝盖肿胀疼痛。关节内注射皮质类固醇后疼痛和肿胀恶化,炎症参数增加。因此,患者接受关节镜灌洗和静脉注射抗生素治疗,怀疑是化脓性关节炎。采集滑液和滑膜样品并送去进行微生物学分析。滑液细胞学见白细胞增多,10,980×106/L,而聚合酶链反应和培养物又无菌了。后来从粪便样品中检测到艰难梭菌毒素,患者口服万古霉素治疗。对患者进行了人类白细胞抗原B27的检测,该抗原为阳性。我们回顾了有关区分脓毒症和反应性关节炎的挑战的文献。以及某些患者易患这种风湿病的机制。
    结论:区分感染性和反应性膝关节关节炎仍然是一个挑战,确定反应性关节炎的确切原因更具挑战性。这个人类白细胞抗原B27阳性患者的病例报告强调了考虑不同的必要性,作为明显的败血症感染的鉴别诊断,膝关节肿胀的少见原因。特别是在2019年冠状病毒病时代。对患者进行化脓性关节炎的治疗可预防此类疾病的任何可能的并发症,而治疗艰难梭菌感染有助于症状的实质性缓解。
    BACKGROUND: Reactive arthritis and septic arthritis rarely present concomitantly in the same joint and patient. Reactive arthritis presenting after coronavirus disease 2019 is also exceedingly rare, with less than 30 cases reported thus far. Less common pathogens such as Clostridium difficile have been reported to cause reactive arthritis, especially in patients with a positive human leukocyte antigen B27, and therefore should be considered in diagnostic algorithms. The aim of this case report is to highlight the difficulties and precautions in discerning and diagnosing patients presenting with sudden swelling of the knee.
    METHODS: We report the case of a 70-year-old Caucasian male with a recent history of coronavirus disease 2019 upper respiratory infection and diarrhea and negating trauma, who presented with a swollen and painful knee. Pain and swelling worsened and inflammatory parameters increased after an intraarticular corticosteroid injection. The patient was therefore treated with arthroscopic lavage and intravenous antibiotics for suspected septic arthritis. Synovial fluid and synovium samples were taken and sent for microbiological analysis. Synovial fluid cytology showed increased leukocytes at 10,980 × 106/L, while polymerase chain reaction and cultures came back sterile. Clostridium difficile toxin was later detected from a stool sample and the patient was treated with oral vancomycin. The patient was tested for the presence of human leukocyte antigen B27, which was positive. We present a review of the literature about the challenges of distinguishing septic from reactive arthritis, and about the mechanisms that predispose certain patients to this rheumatological disease.
    CONCLUSIONS: It is still a challenge to differentiate between septic and reactive arthritis of the knee, and it is even more challenging to identify the exact cause of reactive arthritis. This case report of a human leukocyte antigen-B27-positive patient highlights the necessity of contemplating different, less common causes of a swollen knee joint as a differential diagnosis of an apparent septic infection, especially in the coronavirus disease 2019 era. Treating the patient for septic arthritis prevented any possible complications of such a condition, while treating the C. difficile infection contributed to the substantial relief of symptoms.

    运动功能和认知过程密切相关。在人类中,这种联系反映在电机系统状态的变化,当一个动作必须准备和停止。单脉冲经颅磁刺激显示,动作准备和动作停止均伴有皮质脊髓兴奋性降低,称为准备和反应抑制,分别。虽然以前已经努力广泛地描述这两种现象,缺乏对这两种现象的更新和全面的比较。为了改善这种赤字,这篇综述的重点是单线圈(单脉冲和配对脉冲)和双线圈TMS结果测量在人类动作准备和动作停止过程中的作用和解释.为此,它旨在识别共性和差异,详细说明基于TMS的结果指标如何受到各州的影响,性状,以及这两个过程中的精神病理学。最终,调查结果将被比较,和开放的问题将被解决,以帮助未来的研究。
    Motor functions and cognitive processes are closely associated with each other. In humans, this linkage is reflected in motor system state changes both when an action must be prepared and stopped. Single-pulse transcranial magnetic stimulation showed that both action preparation and action stopping are accompanied by a reduction of corticospinal excitability, referred to as preparatory and response inhibition, respectively. While previous efforts have been made to describe both phenomena extensively, an updated and comprehensive comparison of the two phenomena is lacking. To ameliorate such deficit, this review focuses on the role and interpretation of single-coil (single-pulse and paired-pulse) and dual-coil TMS outcome measures during action preparation and action stopping in humans. To that effect, it aims to identify commonalities and differences, detailing how TMS-based outcome measures are affected by states, traits, and psychopathologies in both processes. Eventually, findings will be compared, and open questions will be addressed to aid future research.

    这项研究的目标是研究零视力策略,并开发一个有助于减少伤害的模型,事故,和死亡。反过来,这种模式旨在提高幸福感,安全,和制造业的生产力。这项研究对与零愿景相关的知名期刊进行了全面的理论综述,一般制造业,特别是金属制造业。该研究还通过与业内选定的该领域专业团队进行讨论,对VisionZero策略模型进行了验证。这项研究的结果表明,与VisionZero策略相关的研究尚未广泛传播或普及。它进一步揭示了制造业主要基于传统的工作环境原则运作,而不是积极接受零愿景的概念和原则。该研究还发现,以前对零愿景的研究主要集中在道路交通事故上,受伤,和死亡。相比之下,在制造业进行的研究主要审查了与安全有关的方面,健康,和工人的福祉。然而,这些研究往往未能使其目标与提高生产率的首要任务充分保持一致,特别是在工业革命的背景下。由于与VisionZero相关的研究有限,以及研究数据库的新领域,设定比较目标和制定严格的战略可能不是开发模型的最终结果。这项研究的结果可以为政策制定者和立法者提供有价值的见解,以加强支持行业生产力的工作场所健康和安全法规。这项研究代表了开发新的愿景零战略模型的开创性努力,该模型与生产力目标保持一致,并强调基于知识的方法来减少或消除伤害。事故,和死亡。
    This study target is to investigate Vision Zero strategy & develop a model that contributes to the reduction of injuries, accidents, and fatalities. In turn, this model aims to enhance the well-being, safety, and productivity of the manufacturing sector. The study has conducted comprehensive theoretical reviews from reputable journals that are relevant to Vision Zero, manufacturing industries in general, and specifically the metal manufacturing industries. The study also underwent a validation of the Vision Zero strategy model by discussing with a selected professional team in this field from the industry. The results of this study shows that research related to the Vision Zero strategy has not been widely disseminated or popularized. It further reveals that manufacturing industries predominantly operate based on traditional work environmental principles, rather than actively embracing the concepts and principles of Vision Zero. The study has also uncovered that previous research on Vision Zero primarily focused on road accidents, injuries, and fatalities. In contrast, studies conducted in the manufacturing sector primarily examined aspects related to safety, health, and worker well-being. However, these studies often failed to sufficiently align their objectives with the overarching priority of enhancing productivity, especially within the context of the industrial revolution. Due to the limited studies related to Vision Zero and a new area for the research database, setting comparative goals and developing a stringent strategy may not be the final outcome here with the developed model. The results of this research could provide valuable insights to policymakers & lawmakers in order to enhance workplace health and safety regulations which support industries\' productivity. This study represents a pioneering effort in developing a new Vision Zero strategy model that aligns with productivity goals and emphasizes knowledge-based approaches for reducing or eliminating injuries, accidents, and fatalities.

    随着时间的推移,围绕以皮肤受累最少的急性粘膜炎为特征的临床综合征的术语一直是争论的主题。近年来,诸如支原体引起的皮疹和粘膜炎以及反应性感染性皮肤粘膜皮疹(RIME)等术语已被引入,以涵盖与呼吸道感染相关的轻度皮肤粘膜疾病,对管理和预后有影响。我们报告了成人患者中与肺炎衣原体感染相关的复发性RIME病例。由于错误分类和缺乏对潜在病原体的测试,RIME可能被低估。从患者的角度来看,早期识别复发性RIME尤其令人感兴趣,以减少住院的频率和持续时间。
    The terminology surrounding the clinical syndrome characterized by acute mucositis with minimal skin involvement has been a subject of debate over time. In recent years, terms such as mycoplasma-induced rash and mucositis and reactive infectious mucocutaneous eruption (RIME) have been introduced to encompass milder mucocutaneous diseases associated with respiratory infections, with implications for management and prognosis. We report the first case of recurrent RIME associated with Chlamydophila pneumoniae infection in an adult patient. RIME is likely underreported due to misclassification and a lack of testing for potential pathogens. Early recognition of recurrent RIME is of particular interest from the patient\'s perspective to reduce the frequency and duration of hospital admissions.
