Outcomes after occupational therapy intervention for traumatic brachial plexus injury: A prospective longitudinal cohort study

Study DesignProspective longitudinal cohort study.IntroductionTraumatic brachial plexus injuries (BPIs) can be devastating and negatively impact daily function and quality of life. Occupational therapists play an important role in rehabilitation; however, studies identifying outcomes are lacking.PurposeThis study aims to describe outcomes including motor recovery, upper limb function, participation, pain, and quality of life for people receiving occupational therapy intervention.MethodsA convenience sample of English-speaking adults (n = 30) with a traumatic BPI, attending the clinic between December 1, 2014, to November 30, 2016, participated. Participants received occupational therapy focusing on sensorimotor retraining and activity-based rehabilitation. Data on active range of motion (goniometry), strength (Medical Research Council (MRC)), upper-limb function (UEFI15, QuickDASH), participation (PSFS), pain (Brief Pain Inventory), and quality of life (EQ-5D-3L) were collected at baseline, 3, 6, 9, and 12 months.ResultsElbow flexion strength showed significant improvement at all time-points, average increase 2.17 (MRC) (95% confidence interval: 1.29-3.04; P < .001) and mean final MRC grading 3.86 (standard error: 0.44). Significant improvements at 12 months were seen in: shoulder abduction strength and range, flexion strength and range, external rotation range; elbow extension strength and flexion range; thumb flexion and extension strength. Upper limb function (QuickDASH) showed significant improvement (mean change = 18.85; 95% confidence interval: 4.12-33.59; P = .02). Forearm protonation range and finger flexion strength were significantly worse. Remaining outcomes did not show significant improvement.ConclusionsOccupational therapy with surgical intervention can improve strength, range, and upper limb function with people following traumatic BPI. Further investigations into impact on participation, pain, and quality of life are required.     

A Multi-Scale DNN Algorithm for Nonlinear Elliptic Equations with Multiple Scales

Algorithms based on deep neural networks (DNNs) have attracted increasing attention from the scientific computing community. DNN based algorithms are easy to implement, natural for nonlinear problems, and have shown great potential to overcome the curse of dimensionality. In this work, we utilize the multi-scale DNN-based algorithm (MscaleDNN) proposed by Liu, Cai and Xu (2020) to solve multi-scale elliptic problems with possible nonlinearity, for example, the p-Laplacian problem. We improve the MscaleDNN algorithm by a smooth and localized activation function. Several numerical examples of multi-scale elliptic problems with separable or non-separable scales in low-dimensional and high-dimensional Euclidean spaces are used to demonstrate the effectiveness and accuracy of the MscaleDNN numerical scheme.     

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BackgroundDistal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.ObjectivesThis study sought to comprehensively evaluate hand function in patients undergoing DRA.MethodsReal-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.ResultsData of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.ConclusionsIn a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.     

Gd-EOB-DTPA增强MRI评估功能性肝体积与肝功能Child-Pugh分级的相关性

目的：对比解剖性肝脏体积（ALV）和功能性肝脏体积（FLV）与肝功能Child-Pugh分级的相关性。方法：选择温州医科大学附属第二医院育英儿童医院2014年1月至2019年4月同时行增强CT和Gd-EOB-DTPA增强MRI扫描的肝硬化患者25例。对所有患者进行肝功能Child-Pugh评分，检测所有入组患者每个肝段的Gd-EOB-DTPA增强MRI平扫期和肝胆特异期的信号对比增强率（CER），以CT扫描的数据为基础利用MI-3DVS计算每个肝段的ALV和全肝的FLV。分析ALV和FLV与肝功能Child-Pugh分级的相关性。结果：肝功能Child-Pugh分级与ALV呈负相关（r=-0.792，P＜0.001），曲线拟合的决定系数（R2）=0.63；肝功能Child-Pugh分级与FLV亦呈负相关（r=-0.911，P＜0.001），曲线拟合的R2=0.80。FLV与肝功能Child-Pugh分级有更显著的负相关性。结论：结合Gd-EOB-DTPA增强MRI平扫期和肝胆特异期的信号CER和ALV计算所得的FLV较ALV能更好地反映肝脏的功能状态。
