Voluntary ambulation using voluntary upper limb muscle activity and Hybrid Assistive Limb® (HAL®) in a patient with complete paraplegia due to chronic spinal cord injury: A case report

Context: We sought to describe our experience with the Hybrid Assistive Limb® (HAL®) for active knee extension and voluntary ambulation with remaining muscle activity in a patient with complete paraplegia after spinal cord injury.

Findings: A 30-year-old man with complete paraplegia used the HAL® for 1 month (10 sessions) using his remaining muscle activity, including hip flexor and upper limb activity. Electromyography was used to evaluate muscle activity of the gluteus maximus, tensor fascia lata, quadriceps femoris, and hamstring muscles in synchronization with the Vicon motion capture system. A HAL® session included a knee extension session with the hip flexor and voluntary gait with upper limb activity. After using the HAL® for one month, the patient’s manual muscle hip flexor scores improved from 1/5 to 2/5 for the right and from 2/5 to 3/5 for the left knee, and from 0/5 to 1/5 for the extension of both knees.

Conclusion/clinical relevance: Knee extension sessions with HAL®, and hip flexor and upper-limb-triggered HAL® ambulation seem a safe and feasible option in a patient with complete paraplegia due to spinal cord injury.     

生长抑素及其类似物联合质子泵抑制剂应用于急性非静脉曲张性上消化道出血的循证分析

目的 系统评价生长抑素及其类似物联合质子泵抑制剂（proton pump inhibitor，PPI）治疗急性非静脉曲张性上消化道出血（acute non-variceal upper gastrointestinal bleeding，ANVUGIB）的有效性和安全性，并分析其用药经济性。方法 采用循证医学方法搜集生长抑素及其类似物联合PPI治疗ANVUGIB的RCT、队列研究进行meta分析，得到相应的有效性及安全性分析结果，并进行成本-效果分析。结果 最终纳入6个RCT均未接受内镜治疗，共610例受试者。Meta分析结果显示，生长抑素及其类似物联合高、中、低剂量PPI治疗在以下方面均优于单用高、中、低剂量PPI治疗，差异有统计学意义，总有效率[OR=3.34，95%CI（2.03，5.47），P<0.000 01]、止血时间[MD=-9.04，95%CI（-11.69，-6.38），P<0.000 01]、输血量[MD=-1.10，95%CI（-1.46，-0.74），P<0.000 01]；在不良反应发生率方面，2组差异无统计学意义[OR=0.49，95%CI（0.11，2.12），P=0.34]。ANVUGIB患者予生长抑素联合高、中、低剂量奥美拉唑与单用高、中、低剂量奥美拉唑进行成本-效果分析，增量成本效果比分别为172.28，217.26，330.37，敏感性分析后显示结果稳定。而接受内镜治疗后应用生长抑素及其类似物联合PPI治疗仅1个队列研究，研究结果显示内镜治疗成功后联合治疗并不优于PPI单药治疗。结论 现有证据表明，生长抑素及其类似物联合PPI治疗未经内镜治疗的ANVUGIB患者为较有效的方案，两者安全性相当、耐受性较好，从药品直接成本考虑，高剂量PPI组联合治疗较中、低剂量PPI组联合治疗更具有成本效果性。而对于经内镜下止血治疗的患者两者疗效相当，可考虑单用PPI。     

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.     

SI和DBP对女性产后出血的风险预测效果

目的考察休克指数(shock index,SI)和舒张压(diastolic blood pressure,DBP)对女性产后出血的风险预测效果。方法选取2016年1月～2018年12月在我院行产检并分娩的320例产后出血孕妇作为研究组,另外选取同期进行正常分娩的健康孕妇240例作为对照组,比较两组患者的一般临床资料、血红蛋白(hemoglobin,Hb)、舒张压(diastolic blood pressure,DBP)、收缩压(systolic blood pressure,SBP)、心率(heart rate,HR)及休克指数(shock index,SI),并采用Ordinal逻辑回归分析各参数对产后出血的风险预警。结果两组患者在年龄、孕周、BMI及新生儿体重相比,差异无统计学意义(P0.05),而孕次相比,差异具有统计学意义(P0.05);与对照组产后24 h相比,研究组产后24 h患者的DBP、SBP及Hb均显著降低,而HR和SI显著升高(P0.05);与对照组产前相比,产后24 h患者的SBP、HR及SI显著降低(P0.05);与研究组产前相比,产后24 h患者的DBP、SBP、HR及Hb均显著降低,而SI显著升高,差异具有统计学意义(P0.05);Ordinal逻辑回归分析结果显示,休克指数和舒张压对产后出血具有预警作用(P0.05)。结论休克指数和舒张压可作为评估女性产后出血的风险预测指标,临床应密切监护。

Time-Driven Activity-Based Cost Comparison of Three Imaging Pathways for Suspected Midgut Volvulus in Children

ObjectiveTo use time-driven activity-based costing to compare the costs of pathways for evaluating suspected pediatric midgut volvulus using either fluoroscopic upper gastrointestinal examination (UGI) or focused abdominal ultrasound (US).MethodsProcess maps were created through patient shadowing, medical record review, and frontline staff interviews. Using time-driven activity-based costing methodology, practical capacity cost rates were calculated for personnel, equipment, and facility costs. Supply costs were included at institutional purchase prices. The cost of each process substep was determined by multiplying step-specific capacity costs by the median time required for each step, and substep costs were summed to generate total pathway cost. Multivariate sensitivity analyses were performed applying minimum and maximum labor costs. Assuming UGI would be used to troubleshoot nondiagnostic US, a break-even analysis was performed to determine the cost impact of varying frequencies of UGI on the total cost of the US-based pathway.ResultsProcess maps were created from 105 (48 girls, 57 boys) patient encounters. Base case pathway times were 90 min (UGI) and 55 min (US). Base case cost for UGI was $282.74 (range: $170.86-$800.82) when performed by a radiology practitioner assistant and $545.66 (range: $260.97-$1,974.06) when performed by a radiologist. Base case cost for US was $155.67 (range: $122.94-$432.29) when performed by a sonographer and $242.64 (range: $147.46-$1,330.05) when performed by a radiologist. For a US-based pathway, the total cost break-even pathway mix (percent UGI required for troubleshooting) was 57%.ConclusionUS can be a faster and less costly alternative to UGI in pediatric patients with suspected midgut volvulus.
