Objective
To evaluate the impact of white matter changes on neurologic outcomes after total arch replacement using antegrade cerebral perfusion.Methods
White matter changes were assessed using a visual Fazekas scale on preoperative magnetic resonance images. From October 1999 to December 2016, 359 patients who had demonstrated changes on preoperative magnetic resonance imaging underwent elective total arch replacement using antegrade cerebral perfusion. Patients were classified into 3 severity groups: mild (100 patients), moderate (158 patients), and severe (101 patients). Mean follow-up time was 4.8 ± 3.6 years. Multivariate logistic regression methods were used to evaluate for an independent association between white matter changes and postoperative neurological outcomes.Results
Hospital mortality was 2.8% (10/359), and no significant differences were found across the 3 groups (P = .604). Multivariate analysis demonstrated that the severity of white matter change was significantly associated with both postoperative permanent neurologic deficit (odds ratio, 5.77; 95% confidence interval, 1.58-38.4, P = .005) and transient neurologic deficit (odds ratio, 2.46; 95% confidence interval, 1.45-4.37, P < .001).Conclusions
White matter changes, defined using the visual Fazekas scale on preoperative magnetic resonance imaging, were significantly associated with significant postoperative adverse neurologic outcomes after total arch replacement using antegrade cerebral perfusion. 相似文献2.

Two-group randomized controlled trial.Introduction
Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence.Purpose of the Study
The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury.Methods
A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group.Results
After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], ?0.954; P = .348; and 95% confidence interval, ?12.380 to 4.513).Discussion
In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a ‘typical’ position, may not lead to an immediate improvement in hand function.Conclusions
Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term. 相似文献4.

Introduction
We aimed to evaluate if ex vivo machine perfusion could minimize the negative impact of cold ischemia on those renal grafts obtained from controlled donation after circulatory death (cDCD).Material and methods
Prospective observational paired study of kidney transplants from cDCD performed in our center. The kidney from each pair preserved on ice was transplanted first within the first few hours following procurement, while the contralateral kidney was machine-perfused with a LifePort device (Organ Recovery Systems, Brussels, Belgium) and transplanted the following day.Results
A total of 12 cDCDs were included. No differences were observed in delayed graft dysfunction or graft survival between the 2 groups.Conclusion
The use of ex vivo perfusion devices is simple and they do not require any large infrastructural or high economic investments, considering the fact that it allows a better selection of recipients and viable organs no longer need to be discarded because of prolonged warm ischemia times. 相似文献5.

Case series.Introduction
A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature.Purpose of the Study
The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage.Methods
The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries.Results
Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network.Discussion
For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors.Conclusions
This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals. 相似文献6.

Case series.Introduction
Upper extremity (UE) trauma and subsequent immobilization affects functional performance.Purpose of the Study
Determine the usefulness and feasibility of unilateral hand training (UHT) on improving functional performance in patients with UE trauma.Methods
Nine participants received UHT within 10 days of immobilization. Functional performance, dexterity, grip, and pinch strength were measured at initial and 4-week visits. Qualitative interviews were coded to develop themes.Results
All Jebsen-Taylor hand function test subtests improved from pretest to post-test. Disabilities of the Arm, Shoulder and Hand scores of all 9 participants improved. Functional performance was more impaired for participants with dominant UE injury. Four themes emerged: participants were forced to alter or avoid most daily activities, had an increased dependency on others, took longer to perform activities, and felt UHT decreased the impact of UE trauma on function.Discussion
Functional performance was impaired for all participants. Participants believed that UHT was useful and contributed to improved function.Conclusion
This case series tracked a comprehensive intervention based on a holistic activities of daily living framework that considered the nuances of individual complexities of immobilization following hand trauma. Knowledge from this study supports an early intervention like UHT to educate clients on effective strategies to improve immediate activities of daily living functioning and potentially prevent longer term impairments. 相似文献7.

Background
The purpose of this analysis is to describe the differences in cardiac magnetic resonance characteristics between benign and malignant tumors, which would be helpful for surgical planning.Methods
This was a prospective cohort study of 130 patients who underwent cardiac magnetic resonance imaging for evaluation of a suspected cardiac mass. After excluding thrombi and tumors without definitive diagnosis, 66 tumors were evaluated for morphologic features and tissue composition.Results
Of the 66 patients, 39 (59.0%) had malignant tumors and 27 (41.0%) had benign tumors. Patients with malignant tumors were younger when compared with those with benign tumors (age 51 years [42.8-60.0] vs 65 years [60.0-71.0] median). Malignant tumors more often demonstrated tumor invasion (69% vs 0% P < .001) and were more often associated with pericardial effusion (41% vs 7.4% P = .004). Presence of first-pass perfusion (100% vs 33% P < .001) and late gadolinium enhancement (100% vs 59.2%, P < .001) were significantly higher in malignant tumors. In logistic regression modeling, tumor invasion (P < .001) and first-pass perfusion (P < .001) were independently associated with malignancy. Furthermore, using classification and regression tree analysis, we developed a decision tree algorithm to help differentiate benign from malignant tumors (diagnostic accuracy ~90%). The algorithm-weighted cost of misclassifying a malignant tumor as benign was twice that of classifying a benign tumor as malignant.Conclusions
Our study demonstrates that cardiac magnetic resonance imaging is a useful noninvasive method for differentiating malignant from benign cardiac tumors. Tumor size, invasion, and first-pass perfusion were useful imaging characteristics in differentiating benign from malignant tumors. 相似文献8.

Background
This study aimed to identify differences in pattern recognition skill among individuals with varying surgical experience.Methods
Participants reviewed laparoscopic cholecystectomy videos of various difficulty, and paused them when the cystic duct or artery was identified to outline each structure on the monitor. Time taken to identify each structure, accuracy and work load, which was assessed using the NASA-Task Load Index (TLX), were compared among the three groups.Results
Ten students, ten residents and eight attendings participated in the study. Attendings identified the cystic duct and artery significantly faster and more accurately than students, and identified the cystic artery faster than residents. The NASA-TLX score of attendings was significantly lower than that of students and residents.Conclusions
Attendings identified anatomical structures faster, more accurately, and with less effort than students or residents. This platform may be valuable for the assessment and teaching of pattern recognition skill to novice surgeons.Short summary
Accurate anatomical recognition is paramount to proceeding safely in surgery. The assessment platform used in this study differentiated recognition skill among individuals with varing surgical experience. 相似文献10.

Background
Many strategies for venous thromboembolism (VTE) prophylaxis following hip and knee arthroplasty exist, with extensive controversy regarding the optimum strategy to minimize risk of VTE and bleeding complications. Data from the American Board of Orthopedic Surgery Part II (oral) Examination case list database was analyzed to determine efficacy, complication rates, and prescribing patterns for different prophylactic strategies.Methods
The American Board of Orthopedic Surgery case database was queried utilizing Current Procedural Terminology codes 27447 and 27130 for primary total knee and hip arthroplasty, respectively. Geographic region, patient age, gender, deep vein thrombosis prophylaxis strategy, and complications were obtained. Less aggressive prophylaxis patterns were considered if only aspirin and/or sequential compression devises were utilized. More aggressive VTE prophylaxis patterns were considered if any of low-molecular-weight heparin (enoxaparin), warfarin, rivaroxaban, fondaparinux, or other strategies was used.Results
In total, 22,072 cases of primary joint arthroplasty were analyzed from 2014 to 2016. The national rate of less aggressive VTE prophylaxis strategies was 45.4%, while more aggressive strategies were used in 54.6% of patients. Significant regional differences in prophylactic strategy patterns exist between the 6 regions. The predominant less aggressive prophylaxis pattern was aspirin with sequential compression devises at 84.8% with 14.8% receiving aspirin alone. Use of less aggressive prophylaxis strategy was significantly associated with patients having no complications (95.5% vs 93.0%). Use of more aggressive prophylaxis patterns was associated with higher likelihood of mild thrombotic (0.9% vs 0.2%), mild bleeding (1.3% vs 0.4%), moderate thrombotic (1.2% vs 0.4%), moderate bleeding (2.7% vs 2.1%), severe thrombotic (0.1% vs 0.0%), severe bleeding events (1.2% vs 0.9%), infections (1.9% vs 1.3%), and death within 90 days (0.7% vs 0.3%). Similar results were found in subgroup analysis of total hip and knee arthroplasty patients.Conclusion
It was not possible to ascertain the individual rationale for use of more aggressive VTE prophylaxis strategies; however, more aggressive strategies were associated with higher rates of bleeding and thrombotic complications. Less aggressive strategies were not associated with a higher rate of thrombosis.Level of Evidence

Study Design
A within-subject research design was used in this study. The difference of the range of motion (ROM) with and without ulnar nerve block was analyzed.Introduction
For the clinical evaluation of the functional effects of ulnar nerve palsy at the hand the relevance of clinical tests is in discussion.Purpose of the Study
The aim of the study was to evaluate the predictive value of 2 clinical tests for a simulated ulnar nerve lesion by motion analysis with a sensor glove.Methods
In 28 healthy subjects, dynamic measurements of the finger joints were performed by a sensor glove with and without ulnar nerve block at the wrist. In the 0° metacarpophalangeal (MCP) stabilization test, the subjects were asked to stabilize the MCP joints actively in 0° while moving the interphalangeal joints, whereas at the 90° MCP stabilization test, the subjects stabilized the MCP joints actively in the 90° position.Results
In the 0° MCP stabilization test, no remarkable changes of the ROM were found at the MCP joints; at the proximal interphalangeal joints 2-5, the ROM decreased with ulnar nerve block, significantly at the index, middle, and ring fingers (P < .05). In the 90° MCP stabilization test, the average ROM of the MCP joints 2-5 significantly increased with ulnar nerve block (P < .05), whereas at the PIP joints, the average ROM decreased (P < .05).Discussion
The 90° MCP stabilization test had a high predictive value for the discrimination between healthy subjects and subjects with a simulated peripheral ulnar nerve lesion.Conclusions
The results could be relevant for the determination of the functional effect of ulnar nerve palsy and the quantification of clawing in hand rehabilitation.Level of Evidence

Objectives
Structural valve deterioration (SVD) remains a major bioprosthesis-related complication, as recently described for the Mitroflow valve (models LX and 12A) (LivaNova, London, United Kingdom). The real incidence of the SVD risk remains unclear, often due to methodologic pitfalls by systematically using the Kaplan-Meier estimator and/or the Cox model. In this report, we propose for the first time a precise statistical modeling of this issue.Methods
Five hundred sixty-one patients who underwent aortic valve replacement with the aortic Mitroflow valve between 2002 and 2007 were included. We used an illness–death model for interval-censored data. Median follow-up was 6.6 years; 103 cases of SVD were diagnosed.Results
The 4-year and 7-year SVD cumulative incidences after the first anniversary of surgery were 15.2% (95% confidence interval, 11.9-19.1) and 31.0% (95% confidence interval, 25.8-37.2), respectively. Female gender, dyslipidemia, chronic obstructive pulmonary disease, and severe patient-prosthesis mismatch were significant risk factors of SVD. The occurrence of SVD was associated with a 2-fold increase in the risk of death.Conclusions
Appropriate statistical models should be used to avoid underestimating the SVD complication associated with worse long-term survival. 相似文献14.

Background
Improving postoperative pain control may lead to improved outcomes including decreased opioid use, shorter hospital stays, and improved patient satisfaction. This study examined the effects of instilling intraperitoneal bupivacaine following laparoscopic appendectomy.Methods
In this prospective, randomized, double-blinded, placebo-controlled study, patients with appendicitis were randomized to receive either the bupivacaine or normal saline instilled at the appendectomy site prior to close. Postoperative pain scores, opioid doses and length of stay were recorded.Results
Pain scores were lower (mean 2.48 versus 3.8; p?=?0.014), and postoperative opioid use was lower (mean 7.394?mg versus 16.921?mg; p?=?0.007) in the bupivacaine group.Conclusions
Instilling bupivacaine at the base of the cecum at the conclusion of laparoscopic appendectomy was associated with reducing postoperative pain scores and in hospital opioid use.Statement
This prospective, randomized, double-blinded, placebo-controlled study enrolled subjects with acute appendicitis undergoing laparoscopic appendectomy. Subjects were randomized to receive either bupivacaine or normal saline intraperitoneally at the close of surgery. In the bupivacaine group, pain scores at 1?h were improved and inpatient postoperative opioid use was less. 相似文献15.

Clinical measurement.Introduction
Common provocative maneuvers to differentiate thumb carpometacarpal (CMC) osteoarthritis from other sources of pain are the grind, metacarpal (MC) flexion, and MC extension tests. A maneuver known as the pressure-shear test is described here.Purpose of the study
To compare the diagnostic value of the grind, metacarpal flexion, metacarpal extension, and pressure-shear tests for CMC osteoarthritis of the thumb.Methods
The diagnostic accuracy of each test was compared in 127 thumbs from 104 patients. Sensitivity, specificity, and predictive values of each test were calculated. In a secondary analysis, polychoric correlation coefficients were used to assess the correlation of each test with severity defined by Eaton-Littler stage.Results
The overall diagnostic accuracy of the thumb MC grind, pressure-shear, flexion, and extension tests were 70%, 98%, 47%, and 55%, respectively. The sensitivities were 64%, 99%, 36%, and 46%, respectively, and specificities were 100%, 95%, 100%, and 100%, respectively. For the diagnosis of Thumb CMC arthritis, the MC pressure-shear test was superior overall in terms of overall diagnostic accuracy and sensitivity, while having comparable specificity to the other maneuvers.Conclusion
The pressure-shear test was found to be superior to the commonly used grind maneuver and the provocative maneuvers of MC flexion and extension tests to confirm diagnosis of CMC osteoarthritis. 相似文献16.

Introduction
The aim of this study was to determine whether complications following mastectomy with immediate breast reconstruction (IBR) were associated with breast cancer recurrence.Methods
A retrospective review was performed of women diagnosed with stage I-III breast cancer who underwent mastectomy with IBR between 2005 and 2010. Patient demographics, tumor data, surgical wound complications, treatment details and timing were recorded and analyzed.Results
We identified 458 women with a median follow up time of 7.6 years. A total of 22% of patients experienced IBR complications. There was a delay in initiation of adjuvant therapy in patients who had a complication (52 vs 41 days, p?<?0.001). There was no significant difference in recurrences between groups with and without complications (p?=?0.65).Conclusions
In breast cancer patients who undergo mastectomy with IBR, wound complications delayed initiation of adjuvant systemic therapy, but were not associated with an increased risk of cancer recurrence. 相似文献18.

Introduction
Several studies demonstrated that simulator-acquired skill transfer to the operating room is incomplete. Our objective was to identify trainee characteristics that predict the transfer of simulator-acquired skill to the operating room.Methods
Trainees completed baseline assessments including intracorporeal suturing (IS) performance, attentional selectivity, self-reported use of mental skills, and self-reported prior clinical and simulated laparoscopic experience and confidence. Residents then followed proficiency-based laparoscopic skills training, and their skill transfer was assessed on a live-anesthetized porcine model. Predictive characteristics for transfer test performance were assessed using multiple linear regression.Results
Thirty-eight residents completed the study. Automaticity, attentional selectivity, resident perceived ability with laparoscopy and simulators, and post-training IS performance were predictive of IS performance during the transfer test.Conclusions
Promoting automaticity, self-efficacy, and attention selectivity may help improve the transfer of simulator-acquired skill. Mental skills training and training to automaticity may therefore be valuable interventions to achieve this goal. 相似文献19.

Background
In 2008, 2005–2006 National Surgical Quality Improvement Program (NSQIP) data were used to identify surgical operations contributing disproportionately to morbidity and mortality. Since then, numerous enhanced recovery programs have been utilized to augment quality improvement efforts. This study reassesses procedural complication incidence after a decade of quality improvement efforts.Methods
Data from the 2015 NSQIP were used. The same original 36 general surgery procedure groups were created using Current Procedural Terminology codes. Ninety percent of our 409,230 patients matched into a procedure group and adverse event rates were analyzed for each.Results
Ten procedure groups accounted for 80% of adverse events. Colectomy ranked the highest for adverse events (34%), readmissions (27%) and mortality rates (45.8%). For outpatient cholecystectomy, the relative percent point difference for adverse events has increased by 224% since 2005.Conclusion
Refocusing on colectomy and outpatient cholecystectomy represent current priorities in general surgery. 相似文献20.
