    局部枸橼酸抗凝是危重患者肾脏替代治疗的首选选择。然而,目前的实施忽略了患者离子钙水平波动中可能存在的个体差异。为了解决这个问题,根据枸橼酸盐的药动学和清除率特点,建立个体化枸橼酸盐和钙补充模型,以这些模型为核心,建立了自动化的局部枸橼酸抗凝系统,以促进临床患者的治疗。本研究旨在初步评估该系统的安全性和有效性。SuperbMed®RCA-SP100自动化局部柠檬酸抗凝系统,长期间歇性肾脏替代疗法。
    7名接受长期间歇性肾脏替代治疗的患者完成了SuperbMed®RCA-SP100系统的治疗。在透析开始之前和之后每小时测量体内和体外离子钙水平。还监测了泵的准确性和警报灵敏度。
    在7次治疗中,体外离子钙平均水平为0.34±0.02mmol/L,体内离子钙水平平均为1.09±0.07mmol/L。没有患者需要干预,没有过滤器凝固。泵的绝对精度均小于5%,警报可以精确触发。
    我们报道了一种自动化系统,该系统允许在长期间歇性肾脏替代治疗中个体化补充柠檬酸盐和钙,并能够精确和安全地实施局部柠檬酸盐抗凝。
    UNASSIGNED: Regional citrate anticoagulation is a preferred option for renal replacement therapy in critically ill patients. However, current implementations ignore individual differences that may exist in the fluctuation of patients\' ionized calcium levels. To address this problem, individualized citrate and calcium supplementation models were established based on the pharmacokinetic and clearance characteristics of citrate, and an automated regional citrate anticoagulation system was built with these models as its core to facilitate the treatment of clinical patients. This study was designed to preliminarily evaluate the safety and efficacy of this system, the SuperbMed® RCA-SP100 automated regional citrate anticoagulation system, in prolonged intermittent renal replacement therapy.
    UNASSIGNED: Seven patients undergoing prolonged intermittent renal replacement therapy completed treatment with the SuperbMed® RCA-SP100 system. In vivo and in vitro ionized calcium levels were measured every hour before and after the start of dialysis. The accuracy and alarm sensitivity of the pumps were also monitored.
    UNASSIGNED: During seven treatments, the average extracorporeal ionized calcium level was 0.34 ± 0.02 mmol/L, and the mean ionized calcium level in vivo was 1.09 ± 0.07 mmol/L. No patient required intervention, and there was no filter coagulation. The pumps all had an absolute accuracy less than 5%, and alarms could be triggered precisely.
    UNASSIGNED: We reported on an automated system that allows for individualized citrate and calcium supplementation in prolonged intermittent renal replacement therapy and enables the precise and secure implementation of regional citrate anticoagulation.

    UNASSIGNED: Patients with gastric cancer (GC) who underwent radical surgery require long-term follow-up (usually 5 years). The purpose of this study was to explore individualized follow-up strategies for patients with GC.
    UNASSIGNED: This is a retrospective cohort study that established a clinicopathologic database of patients who underwent gastrectomy from January 2010 to December 2020 at Ningbo No. 2 Hospital. Follow-up was performed until March 2023. The rate of new-onset recurrence of patients with GC was explored annually according to different pTNM stages, defining a recurrence rate of less than 1% as adequate follow-up time.
    UNASSIGNED: Of the 1606 patients who were eligible, the total number of patients who completed the 5- and 10-year follow-up was 1107 and 586, respectively. A total of 444 cases were diagnosed with recurrence. The recurrence rate for stage IA patients was consistently less than 1% during the follow-up time. The adequate follow-up time (the rate of new-onset recurrence less than 1%) was 5 years for stage IB and IIA patients, and 8 years for stage IIB and IIIA patients, respectively. In contrast, stage IIIB patients were always at risk of recurrence during the follow-up time (>1%). Time to a new recurrence rate for stage IIIC patients was 6 years.
    UNASSIGNED: Among patients who underwent radical gastrectomy, the rate of new-onset recurrence varied among patients with different pTNM stages. This study suggests that the follow-up of GC can be individualized and refer to pTNM stage.

    在这项研究中,开发了一种个性化,稳定的被动控制下肢外骨骼机器人。用户的关节角度和其中一个鞋底的压力中心(CoP)被输入到卷积神经网络(CNN)-长短期记忆(LSTM)模型中,以评估和调整外骨骼控制方案。CNN-LSTM模型预测控制方案的适应度,并将结果输出到外骨骼机器人,对其控制参数进行了相应的修改,提高了行走稳定性。在正常行走和具有发达外骨骼的被动行走期间,唯一的CoP具有相似的趋势;有和没有外骨骼的CoP的坐标具有91%的相关性。此外,来自股直肌的肌电图信号显示,在发达系统中以稳定的步幅行走时,与以不稳定的步幅行走时相比,它施加的力减少了40%。因此,开发的下肢外骨骼可用于帮助用户实现平衡和稳定的步行与减少的力量。在未来,中风和下肢无力的患者可以使用这种外骨骼来实现稳定的行走。
    In this study, an individualized and stable passive-control lower-limb exoskeleton robot was developed. Users\' joint angles and the center of pressure (CoP) of one of their soles were input into a convolutional neural network (CNN)-long short-term memory (LSTM) model to evaluate and adjust the exoskeleton control scheme. The CNN-LSTM model predicted the fitness of the control scheme and output the results to the exoskeleton robot, which modified its control parameters accordingly to enhance walking stability. The sole\'s CoP had similar trends during normal walking and passive walking with the developed exoskeleton; they-coordinates of the CoPs with and without the exoskeleton had a correlation of 91%. Moreover, electromyography signals from the rectus femoris muscle revealed that it exerted 40% less force when walking with a stable stride length in the developed system than when walking with an unstable stride length. Therefore, the developed lower-limb exoskeleton can be used to assist users in achieving balanced and stable walking with reduced force application. In the future, this exoskeleton can be used by patients with stroke and lower-limb weakness to achieve stable walking.

    近年来,对个体化治疗效果的预测越来越感兴趣.虽然关于这种模型发展的文献正在迅速增长,关于他们的业绩评估的文献很少。在本文中,我们旨在促进个体化治疗效果预测模型的验证.感兴趣的估计是基于潜在结果框架定义的,这有助于对现有措施和新措施进行比较。特别是,我们研究现有的福利歧视措施(福利歧视的变化),并提出基于模型的扩展,以治疗效果设置为区分和校准指标,在结果风险预测中有很强的基础。主要关注具有二元终点的随机试验数据以及提供个性化治疗效果预测和潜在结果预测的模型。我们使用模拟数据来深入了解所考虑的所检查的辨别和校准统计数据的特征,并进一步说明急性缺血性中风治疗试验中的所有方法。结果表明,所提出的基于模型的统计在偏差和准确性方面具有最佳特征。虽然重抽样方法根据发展数据中业绩估计的乐观情绪进行了调整,他们在重复之间有很高的差异,这限制了他们的准确性。因此,个体化治疗效果模型在独立数据中得到了最好的验证.为了帮助实施,在R中提供了所提出方法的软件实现。
    In recent years, there has been a growing interest in the prediction of individualized treatment effects. While there is a rapidly growing literature on the development of such models, there is little literature on the evaluation of their performance. In this paper, we aim to facilitate the validation of prediction models for individualized treatment effects. The estimands of interest are defined based on the potential outcomes framework, which facilitates a comparison of existing and novel measures. In particular, we examine existing measures of discrimination for benefit (variations of the c-for-benefit), and propose model-based extensions to the treatment effect setting for discrimination and calibration metrics that have a strong basis in outcome risk prediction. The main focus is on randomized trial data with binary endpoints and on models that provide individualized treatment effect predictions and potential outcome predictions. We use simulated data to provide insight into the characteristics of the examined discrimination and calibration statistics under consideration, and further illustrate all methods in a trial of acute ischemic stroke treatment. The results show that the proposed model-based statistics had the best characteristics in terms of bias and accuracy. While resampling methods adjusted for the optimism of performance estimates in the development data, they had a high variance across replications that limited their accuracy. Therefore, individualized treatment effect models are best validated in independent data. To aid implementation, a software implementation of the proposed methods was made available in R.

    背景:骨折的愈合潜力由机械和生物学因素决定。基于模拟的工作流可以帮助评估这些因素,以帮助预测不结合。这项研究的目的是基于临床可用信息,为新型患者特定的模拟工作流程引入两个用例。方法:所使用的软件是“Ulm骨愈合模型”的扩展,并应用于2例骨折固定后出现不愈合的病例,以显示其主要可行性。临床和影像学信息,从最初的治疗开始,用于进料模拟过程。结果:模拟预测了机械驱动的不愈合中的不愈合发展和轴向偏差。在生物不结合的情况下,一个缓慢的,正确识别了不完整的愈合过程。然而,在模拟和临床病例中明显较慢的愈合反应之间,愈伤组织桥接的时间偏移不一致。结论:两个临床用例中提出的模拟工作流程允许根据可用的临床和影像学信息,在初始固定后立即识别有即将发生不愈合风险的骨折。需要在大型非工会队列中进行进一步验证,以提高模型的精度,尤其是在具有生物学挑战性的情况下,并显示其作为筛选工具的有效性。
    Background: The healing potential of a fracture is determined by mechanical and biological factors. Simulation-based workflows can help assess these factors to assist in predicting non-unions. The aim of this study was the introduction of two use cases for a novel patient-specific simulation workflow based on clinically available information. Methods: The used software is an extension of the \"Ulm Bone Healing model\" and was applied in two cases with non-union development after fracture fixation to show its principal feasibility. The clinical and radiographic information, starting from initial treatment, were used to feed the simulation process. Results: The simulation predicted non-union development and axial deviation in a mechanically driven non-union. In the case of a biological non-union, a slow, incomplete healing course was correctly identified. However, the time offset in callus bridging was discordant between the simulation and the distinctly slower healing response in the clinical case. Conclusions: The simulation workflow presented in the two clinical use cases allowed for the identification of fractures at risk for impending non-union immediately after the initial fixation based on available clinical and radiographic information. Further validation in a large non-union cohort is needed to increase the model\'s precision, especially in biologically challenging cases, and show its validity as a screening instrument.

    测量操作员的生理状态并使用该数据来预测未来的性能下降一直是许多运输领域的持续目标。关于陆军航空,这种努力的实现可以导致适应操作员需求的自适应自动化系统的开发。然而,达到这一目的状态需要使用类似于现实生活设置的实验场景,以诱导能够解释个体经验差异的兴趣状态。暴露,以及对工作量操作的感知。在本研究中,我们使用了一种个性化的方法来操纵工作量,以便考虑到响应工作量操纵的个体差异,同时仍然提供与操作相关的飞行经验。
    八名陆军飞行员参加了这项研究,在那里他们完成了对实验室的两次访问。第一次访问的目的是确定个人工作量阈值,第二次访问导致航班进行个性化的工作量处理。两次飞行都收集了脑电图数据,以及工作量和飞行性能的主观评级。
    EEG数据和工作量等级均表明工作量很大。与低工作量飞行相比,高工作量飞行期间的主观评分更高(p<0.001)。关于脑电图,与高工作负荷情景相比,基线飞行情景中的额α(p=0.04)和θ(p=0.01)值较低,β/(α+θ)比值(p=0.02)较高.此外,将这些数据与以前的研究中收集的数据进行了比较,这些研究使用基于群体的方法来操纵工作量.
    个性化方法在脑电图和主观评分中均显示出更高的效果大小,建议使用这种方法可以提供一种更可靠的方式来产生高的飞行员工作量。
    UNASSIGNED: Measuring an operator\'s physiological state and using that data to predict future performance decrements has been an ongoing goal in many areas of transportation. Regarding Army aviation, the realization of such an endeavor could lead to the development of an adaptive automation system which adapts to the needs of the operator. However, reaching this end state requires the use of experimental scenarios similar to real-life settings in order to induce the state of interest that are able to account for individual differences in experience, exposure, and perception to workload manipulations. In the present study, we used an individualized approach to manipulating workload in order to account for individual differences in response to workload manipulations, while still providing an operationally relevant flight experience.
    UNASSIGNED: Eight Army aviators participated in the study, where they completed two visits to the laboratory. The first visit served the purpose of identifying individual workload thresholds, with the second visit resulting in flights with individualized workload manipulations. EEG data was collected throughout both flights, along with subjective ratings of workload and flight performance.
    UNASSIGNED: Both EEG data and workload ratings suggested a high workload. Subjective ratings were higher during the high workload flight compared to the low workload flight (p < 0.001). Regarding EEG, frontal alpha (p = 0.04) and theta (p = 0.01) values were lower and a ratio of beta/(alpha+theta) (p = 0.02) were higher in the baseline flight scenario compared to the high workload scenario. Furthermore, the data were compared to that collected in previous studies which used a group-based approach to manipulating workload.
    UNASSIGNED: The individualized method demonstrated higher effect sizes in both EEG and subjective ratings, suggesting the use of this method may provide a more reliable way of producing high workload in aviators.

    重复的视觉刺激后,事后阶段分析发现,视觉诱发反应幅度随皮层α振荡阶段而变化,该阶段在时间上与感觉刺激一致。在听觉系统中,这种方法尚未成功揭示听觉诱发或诱发反应的α相位依赖性.这里,我们测试了使用头皮脑电图(EEG)记录跟踪alpha的可行性,并使用在研究设备上实现的新型终点校正希尔伯特变换(ecHT)算法实时播放锁相到个性化alpha相位的声音。根据以前的工作,我们假设声音诱发和诱发反应随声音开始时的α相位和与EEG测量的早期声音诱发反应电位(ERP)一致的α相位而变化。因此,我们使用每个受试者的个性化α频率(IAF)和个体听觉ERP延迟来定义目标波谷和峰值α阶段,允许听觉ERP的早期成分与估计的刺激后波峰和波谷阶段对齐,分别。通过这种闭环和个性化的方法,我们发现在刺激开始后对听觉ERP和alpha振荡产生相反的alpha相位依赖效应。波谷和峰值锁相声音会导致刺激后α水平和频率的不同诱发和诱发调制。虽然需要更多的研究来定位这些相位依赖效应的来源,这些结果表明了包括听觉系统在内的感觉处理的α相位依赖性的一般原理.此外,这项研究证明了使用个性化神经生理指标来实现自动化的可行性,闭环,锁相听觉刺激。重要性陈述健康的成人大脑会产生alpha振荡,个体受试者具有不同的alpha振荡频率,这会影响他们动态处理和关注感官信息的方式。然而,关于感官事件和alpha阶段之间的精细尺度时间动态以及听觉输入处理的相应神经调节,人们知之甚少。在这里,我们使用一种新颖的闭环技术和个性化方法来播放特定额叶α阶段的声音。我们展示了对听觉诱发反应的新的α相位依赖效应,阿尔法水平,α相位相干性和频率。这种个性化的闭环方法在各种神经系统的研究和健康应用中具有潜在的应用,发育和临床疾病。
    Following repetitive visual stimulation, post hoc phase analysis finds that visually evoked response magnitudes vary with the cortical alpha oscillation phase that temporally coincides with sensory stimulus. This approach has not successfully revealed an alpha phase dependence for auditory evoked or induced responses. Here, we test the feasibility of tracking alpha with scalp electroencephalogram (EEG) recordings and play sounds phase-locked to individualized alpha phases in real-time using a novel end-point corrected Hilbert transform (ecHT) algorithm implemented on a research device. Based on prior work, we hypothesize that sound-evoked and induced responses vary with the alpha phase at sound onset and the alpha phase that coincides with the early sound-evoked response potential (ERP) measured with EEG. Thus, we use each subject\'s individualized alpha frequency (IAF) and individual auditory ERP latency to define target trough and peak alpha phases that allow an early component of the auditory ERP to align to the estimated poststimulus peak and trough phases, respectively. With this closed-loop and individualized approach, we find opposing alpha phase-dependent effects on the auditory ERP and alpha oscillations that follow stimulus onset. Trough and peak phase-locked sounds result in distinct evoked and induced post-stimulus alpha level and frequency modulations. Though additional studies are needed to localize the sources underlying these phase-dependent effects, these results suggest a general principle for alpha phase-dependence of sensory processing that includes the auditory system. Moreover, this study demonstrates the feasibility of using individualized neurophysiological indices to deliver automated, closed-loop, phase-locked auditory stimulation.
