    Full Text Available Objective: The aim of this study was to analyze the midterm clinical results of aortic valve replacement with cryopreserved homografts.Materials and Methods: Aortic valve replacement was performed in 40 patients with cryopreserved homograft. The indications were aortic valve endocarditis in 20 patients (50%, truncus arteriosus in 6 patients (15%, and re-stenosis or regurtitation after aortic valve reconstruction in 14 (35% patients. The valve sizes ranged from 10 to 27mm. A full root replacement technique was used for homograft replacement in all patients.Results: The 30-day postoperative mortality rate was 12.5% (5 patients. There were four late deaths. Only one of them was related to cardiac events. Overall mortality was 22.5%. Thirty-three patients were followed up for 67±26 months. Two patients needed reoperation due to aortic aneurysm caused by endocarditis. The mean transvalvular gradient significantly decreased after valve replacement (p<0.003. The last follow up showed that the 27 (82% patients had a normal left ventricular function.Conclusion: Cryopreserved homografts are safe alternatives to mechanical valves that can be used when there are proper indications. Although it has a high perioperative mortality rate, cryopreserved homograft implantation is an alternative for valve replacement, particularly in younger patients and for complex surgical problems such as endocarditis that must be minimalized.

    Conclusion: Our study shows that using biprosthetic valve could reduce the risk of morbidity occurrence in patient who needs valve replacement. However, if medical treatments fail, patients should be referred for surgery. This would reduce the risk of mortality because of lower incident of complications such as atrial fibrillation and morbidities due to younger patients’ population.

    The Bologna-Oxford (BOX) total ankle replacement (TAR) was developed with the aim of achieving satisfactory pain-free movement of the ankle. To date, only one single multicentre study has reported its clinical results. The aim of this study was to conduct an independent review of its mid-term results. We retrospectively reviewed a total of 60 prospectively followed patients in whom 62 BOX TARs had been implanted between 2004 and 2008. We used the American Orthopedic Foot and Ankle Society (AOFAS) score to assess the clinical results. Standardised radiographs taken at the time of final follow-up were analysed by two observers. The overall survival was 91.9% at a mean follow-up of 42.5 months (24 to 71). The mean AOFAS score had improved from 35.1 points (sd 16.6; 4 to 73) pre-operatively to 78.0 (sd 10.7; 57 to 100) at final follow-up (p total of 47 patients (78.3%) were very satisfied or satisfied with the outcome. Five patients required revision for functional limitation or continuing pain.

    We compared stroke occurrence and outcomes between Transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR), both periprocedural and at follow-up. From March 2012 to December 2014, 391 consecutive patients underwent TAVR (N.=290) or isolated SAVR (N.=101), concomitantly. Patients' data were prospectively collected. TAVR patients had more comorbidities. One (0.34%) TIA and 9 (3.11%) strokes occurred in-hospital following TAVR, but no cerebrovascular event occurred after SAVR (P=0.11). One stroke (0.99%) and one TIA (0.99%) were detected in SAVR group within 30 days. Among TAVR patients, one (0.75%) stroke at 6 months, 2 (1.9%) strokes and 2 (1.9%) TIAs at 12 months were diagnosed. Kaplan-Meier analysis revealed that 96% and 99% 12-month CVA free survival following TAVR and SAVR, respectively (P=0.67). Preoperative mean trans-aortic valve systolic pressure gradient higher than 40 mmHg remained as risk factor for stroke in TAVR patients only, OR: 4.48 (CI: 1.2-16.54, P=0.02). One intraoperative death, and 5 (4 with CVA) in-hospital deaths occurred after TAVR; whereas only one patient died in SAVR group (P=0.49). Thirty-day mortality was 3.8% (11/290) for TAVR and 0.99% (1/101) for SAVR patients. SAVR patients' survival was 99% at 6 months, 97.9% at 12, and 96.4% at 24 months, whereas survival in TAVR was 97.5% at 6, 92% at 12, and 73.6% at 24 months (HR: 8.43 (CI: 2.47-28.73), P<0.001). Even with significant differences in patients' baseline characteristics; in-hospital and mid-term stroke rates are not significantly higher following TAVR than SAVR. Although periprocedural stroke is not uncommon in TAVR, mid-term stroke rate is low.

    2012-01-01

    Tri-component, mobile bearing, uncemented, total ankle replacements were introduced after the high failure rates of cemented, highly constrained, first-generation, total ankle replacement implants. A total of 30 primary total ankle replacements in 29 patients (20 males and 9 females) were followed up in the present retrospective study for up to 13 (mean 5.1 ± 4) years. The postoperative functional and radiographic outcomes were measured. Failure was defined as revision of either of the components for any reason or conversion of the total ankle replacement to arthrodesis because of debilitating pain that did not resolve after surgery. Of the 29 patients, 2 underwent revision and 1 underwent arthrodesis. All 3 patients had the malpositioned talar implant revised. The mean American Orthopaedic Foot and Ankle Society score was 81 at 1 year postoperatively. Revision of the tibial or talar component for any reason or conversion of the ankle replacement to arthrodesis was considered failure for the survival analysis. Kaplan-Meier analysis showed a 5-year survival rate of 87.6%. The last failure occurred 23.3 months after surgery.

    2009-09-01

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: is patient-prosthesis mismatch an independent risk factor for 30-day and mid-term overall mortality in adult patients undergoing aortic valve replacement (AVR)? Altogether, almost 400 papers were found using the reported search, of which 22 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The majority of the selected articles have focused their analysis on moderate mismatch defined mostly by the presence of an indexed effective orifice area (IEOA)prosthesis mismatch (PPM) (indexed IEOA0.65 cm(2)/m(2)) is an independent risk factor for 30-day or mid-term overall mortality for adult patients undergoing AVR. An exception could be represented by patients with poor ejection fraction, a condition that can make moderate mismatch a predictor of overall mortality after AVR. On the other hand, severe mismatch is a predictor of overall 30-day or mid-term mortality for patients undergoing AVR independently from the presence of poor ejection fraction. In conclusion, our review suggests that the condition of severe PPM should be always avoided, while the presence of moderate mismatch could be tolerated in patients with normal ejection fraction without any impact on overall survival.

    Full Text Available Objective  To retrospectively analyze the early and midterm outcomes and summarize experiences of coronary artery bypass grafting (CABG combined with valve replacement (VR in patients below or above 65-year-old. Methods  The clinical data of 110 patients, who received valve replacement combined with CABG in the General Hospital of PLA from Apr. 1998 to May 2012, were analyzed retrospectively. The patients were divided into two groups according to their age of ≥65 years (39 cases or 0.05, neither in the mechanical ventilation time, the intensive care time, application of intra-aortic balloon counter pulsation (IABCP, the postoperative hospitalization time, CPB time and cross-clamping time. The patients of ≥65 years were followed up from 2 months to 11 years after surgery, of whom 3 patients were lost to follow-up. One patient died of severe drug eruption in 2 months, another one died of lung cancer 2 years later, 2 patients suffered from cerebral infarction, and the life quality in other patients improved obviously with cardiac function evaluated in class I or Ⅱ. The patients in <65 years group were followed up by 3 months to 12 years. Of whom 8 patients lost the follow-up, two patients who received mechanic valve replacement got complications related to anticoagulation treatment in 3 and 6 years after surgery. One of the two died of severe low cardiac output. Conclusion  The early and mid-term outcomes of CABG combined with valve replacement in elderly patients may be safe and satisfying as in younger patients, so long as the right surgery strategy and the precise perioperative treatment are reasonably applied.

  12. Exam fairness

    CERN Document Server

    Bouville, Mathieu

    2008-01-01

    It is widely agreed that exams must be fair; yet what this exactly means is not made clear. One may mean fairness of treatment, but this merely propagates the fairness or unfairness of pre-existing rules. Fairness of opportunity on the other hand necessarily leads to identical grades for everyone, which clearly makes it inapplicable. Neither view is helpful to make decisions on competing claims: fairness of treatment ignores the problem and fairness of opportunity holds all claims to be equally valid. To escape this deadlock one needs an external criterion to replace fairness viewed as student-student comparison.

    A two-stage collaborative exam is one in which students first complete the exam individually, and then complete the same or similar exam in collaborative groups immediately afterward. To quantify the learning effect from the group component of these two-stage exams in an introductory Physics course, a randomized crossover design was used where each student participated in both the treatment and control groups. For each of the two two-stage collaborative group midterm exams, questions were designed to form matched near-transfer pairs with questions on an end-of-term diagnostic which was used as a learning test. For learning test questions paired with questions from the first midterm, which took place six to seven weeks before the learning test, an analysis using a mixed-effects logistic regression found no significant differences in learning-test performance between the control and treatment group. For learning test questions paired with questions from the second midterm, which took place one to two weeks prio...

    Objective To study the effectiveness of artificial disc replacement for cervical diseases and the adjacent segment degeneration. Methods Between January 2008 and October 2010, 39 cases of cervical spondylosis underwent cervical disc replacement. Of them, there were 20 males and 19 females with an average age of 45.7 years (range, 32-60 years) and an average disease duration of 30 months (range, 1 month to 10 years), including 26 cases of cervical myelopathy, 11 cases of nerve root cervical spondylosis, and 2 cases of mixed cervical spondylosis. Single level disc lesion was observed in 27 cases while bi-level lesion in 12 cases. Prestige disc prosthesis was used in 9 patients, Prodisc-C prosthesis in 4 patients, and Discover disc prosthesis in 26 patients. The neurological functional recovery was assessed after operation by Japanese Orthopaedic Association (JOA) score. The range of motion of replaced segment and adjacent segments was measured (Cobb angle), and Kellgren's X-ray assessment was used to evaluate the degree of adjacent segment degeneration. Results The operation was successfully performed in all cases, with primary healing of all the incisions. All patients were followed up from 12 to 36 months with an average of 23.1 months. JOA score was significantly improved at last follow-up when compared with preoperative score (P 0.05). According to the Kellgren's X-ray assessment, degeneration of the adjacent segments occurred in 5 cases at last follow-up, including 3 cases of degeneration from grade 0 to grade 1 or 2, 1 from grade 1 to grade 2, and 1 from grade 2 to grade 3, with a degeneration rate of 12.8%, but no significant difference was found in degeneration degree when compared with preoperative value (X2=1.793, P=0.406). No degeneration of adjacent segments occurred in 32 patients at 15 months after operation. Conclusion Artificial disc replacement has a good effectiveness in treating cervical spondylosis, which can maintain the range of motion of the

    Issues in Midterm Analysis and Forecasting 1998 (Issues) presents a series of nine papers covering topics in analysis and modeling that underlie the Annual Energy Outlook 1998 (AEO98), as well as other significant issues in midterm energy markets. AEO98, DOE/EIA-0383(98), published in December 1997, presents national forecasts of energy production, demand, imports, and prices through the year 2020 for five cases -- a reference case and four additional cases that assume higher and lower economic growth and higher and lower world oil prices than in the reference case. The forecasts were prepared by the Energy Information Administration (EIA), using EIA`s National Energy Modeling System (NEMS). The papers included in Issues describe underlying analyses for the projections in AEO98 and the forthcoming Annual Energy Outlook 1999 and for other products of EIA`s Office of Integrated Analysis and Forecasting. Their purpose is to provide public access to analytical work done in preparation for the midterm projections and other unpublished analyses. Specific topics were chosen for their relevance to current energy issues or to highlight modeling activities in NEMS. 59 figs., 44 tabs.

  19. The Latin Matura exam

    2003-12-01

    Full Text Available In students' opinion the tasks of this year's Pre-Matura exam are neither too easy nor too difficult. 51 % of  the students claim that the translation from Slovene to Latin is the most difficult task, which is not surprising. The students have to recognise the appropriate grammatical constructions without the help of any comments. In this way they can show their autonomy in the use of  the language. Very high quality of the Latin Matura exam tasks can be clearly seen from graph 3. Namely, the students have quite different opinions on which task is the most difficult and which one the easiest. This means that each student can find the type of a task that suits them most and so they can excel in that particular area. At the oral part of the exam 46 % of the students would like to eliminate the grammar question, as they find it difficult to define grammar rules precisely, while they do not have any problems using them in a sentence. Quite surprisingly there are 20 % who dislike the question from culture and civilisation. Their main argument is that in this way they would be able to save a lot of time and so concentrate on other areas. According to the students, the good points of the Latin Matura exam are: a better insight into Latin language and Roman culture, and a good foundation for further study at the university. As far as the bad points of the exam are concerned, they mostly complain about the translation from Latin to Slovene, as they believe they do not have a lot of freedom in translating. They also wish there were more books with different types of  Matura exercises. Teachers mainly agree with their students, but they also pointed out a certain problem: it can be quite tempting to deal only with the topics appearing at the Latin Matura exam and eliminate all others. Namely, every teacher wants to prepare their students for the exam in the best possible way, as they feel their pedagogical and  professional skills are tested too.

  20. Challenges when introducing electronic exam

    Full Text Available Time pressures often necessitate the use of more efficient exam tools, such as electronic exams (e-exams, instead of traditional paper exams. However, teachers may face challenges when introducing e-exams in a higher education context. This paper describes what kinds of challenges teachers may face when introducing e-exams, based on experiences in Turku University of Applied Sciences (TUAS where e-exams have been used since 2012. For this research, the authors used their personal experiences as administrators and teachers of current e-systems used for e-exams in universities in Turku, Finland. Quantitative data were collected by survey from teachers in TUAS (the case study. The learning management systems, Moodle, Optima and ViLLE, and dedicated e-examination systems, Soft Tutor and Tenttis, were also compared to clarify what kind of features are available in order to ease teachers’ work with examinations. The results identified various challenges during e-exam introduction in TUAS. The paper also provides a list of essential services or features for teachers to ease the introduction of e-exams. Among the analysed systems, ViLLE supported most of the required features, and can be used for both learning management and e-examination systems, providing teachers with one single system, which was found to be important to teachers. The key service found by this paper is ‘support for teachers’, which is in line with previous studies.

    We conducted a prospective, nonrandomized, single-center clinical study to evaluate the safety and midterm effectiveness of microtenotomy using a radiofrequency probe to treat chronic tendinosis of the elbow. All patients had failed conservative treatment for 6 months. The radiofrequency-based microtenotomy was performed using the Topaz Microdebrider (ArthroCare). Patients were followed annually for up to 9 years postoperatively. Pain status was documented using a visual analog scale self-reported measure. Eighty consecutive patients with tendinosis of the elbow were enrolled; 69 patients were treated for lateral epicondylitis and 11 for medial epicondylitis. The duration of follow-up ranged from 6 months to 9 years (mean, 2.5 years). Ninety-one percent of the patients reported a successful outcome. Within the lateral epicondylitis group, the preoperative visual analog scale improved from 6.9 to 1.3 postoperatively and demonstrated an 81% improvement (P ≤ .01). For the medial epicondylitis patients, the preoperative visual analog scale improved from 6.1 to 1.3 after surgery, a 79% improvement (P ≤ .01). No complications were reported. Radiofrequency-based microtenotomy is a safe and effective procedure for elbow epicondylitis. The results are durable with successful outcomes observed at 9 years after surgery.

    Full Text Available The aim of this study was to explore clinical features of renal infarction (RI that may have a role in diagnosis and treatment in our patient cohort and provide data on midterm renal functions. Medical records of patients with diagnosis of acute RI, established by contrast enhanced computed tomography (CT and at least 1 year follow-up data, who were hospitalized in our clinic between 1998 and 2012 were retrospectively reviewed; including descriptive data, clinical signs and symptoms, etiologic factors, laboratory findings, and prescribed treatments. Patients with solitary infarct were treated with acetylsalicylic acid (ASA only, whereas patients with atrial fibrillation (AF or multiple or global infarct were treated with anticoagulants. Estimated Glomerular Filtration Rate (eGFR referring to renal functions was determined by the Modification of Diet in Renal Disease (MDRD formula. Twenty-seven renal units of 23 patients with acute RI were identified. The mean age was 59.7 ± 15.7 years. Fourteen patients (60.8% with RI had atrial fibrillation (AF as an etiologic factor of which four had concomitant mesenteric ischemia at diagnosis. At presentation, 20 patients (86.9% had elevated serum lactate dehydrogenase (LDH, 18 patients (78.2% had leukocytosis, and 16 patients (69.5% had microscopic hematuria. Two patients with concomitant mesenteric ischemia and AF passed away during follow up. Mean eGFR was 70.8 ± 23.2 mL/min/1.73 m2 at admission and increased to 82.3 ± 23.4 mL/min/1.73 m2 at 1 year follow up. RI should be considered in patients with persistent flank or abdominal pain, particularly if they are at high risk of thromboembolism. Antiplatelet and/or anticoagulant drugs are both effective treatment options according to the amplitude of the infarct for preserving kidney functions.

    2017-01-01

    First-year students often become discouraged during introductory biology courses when repeated attempts to understand concepts nevertheless result in poor test scores. This challenge is exacerbated by traditional course structures that impose premature judgments on students’ achievements. Repeated testing has been shown to benefit student ability to recognize and recall information, but an effective means to similarly facilitate skill with higher-order problems in introductory courses is needed. Here, we show that an innovative format that uses a creative grading scheme together with weekly formative midterm exams produced significant gains in student success with difficult items requiring analysis and interpretation. This format is designed to promote tenacity and avoid discouragement by providing multiple opportunities to attempt demanding problems on exams, detailed immediate feedback, and strong incentives to retain hope and improve. Analysis of individual performance trajectories with heat maps reveals the diversity of learning patterns and provides rational means for advising students. PMID:28130269

    2000-09-01

    Poster sessions are effective communication tools common at scientific meetings. The adaptations of poster sessions to the classroom have been reported to be effective evaluation and learning tools in chemistry and other disciplines. However, poster sessions have never been used to replace a standard hourly exam. We report here the use of a poster session as an oral examination in our introductory Integrated Chemistry/Physics/Mathematics course for entering freshmen. The poster exam replaces one traditional, in-class written examination, providing an alternate method of student assessment. Students' communication and organizational skills, their depth of knowledge of a particular topic, and their conceptual understanding of the topic are probed by the poster exam. Students report that the poster exam is more enjoyable and a more effective learning tool than traditional exams.

    The aim of this study was to evaluate mid-term results of endovascular treatment of penetrating aortic ulcers. Between February 2000 and November 2006, 18 consecutive patients underwent endovascular treatment of the descending thoracic aorta (N=16) and abdominal infrarenal aorta (N=2) for penetrating aortic ulcer, in a single University Hospital. Data were prospectively collected and retrospectively analyzed. Mean follow-up was 41 months (range 4 to 77 months). Technical success was achieved in all patients. No perioperative deaths occurred. No conversion to open repair or secondary procedures were required. Two patients died in the follow-up period for reasons not related to penetrating aortic ulcers. One type II endoleak was observed. It was still present, unchanged, twelve months after the procedure. Endovascular treatment of penetrating aortic ulcers of the descending thoracic and infrarenal aorta were safe and effective in the mid-term in this small series of patients.

    Objective To retrospectively analysis and compareabout Bryan artificial cervical disc arthroplasty with ante-rior cervical decompression and fusion (ACDF) on the clinical efficacy for“Skip”cervical spondylosis. Methods From February 2002 to May 2012, 49 cases were treated with Bryan artificial cervical disc arthroplasty (artificial cervical disc replacement surgery group, 18 cases) or anterior cervical decompression and fusion (ACDF group, 31 cases), 29 males and 20 females. Each case was evaluated at the moment of preoperatively, 3 months, 6 and 12 months and last follow-up after surgery by the Japanese Orthopedic Association (JOA), Neck Disability Index (NDI), Visual Analog Scale (VAS), Cervical sagittal curvature, the total cervical spine range of motion(ROM),middle segments of motion. MRI was also used to assess to adjacent segment disc degeneration, spinal cord compression and signal change situation. Results All patients were followed up for more than 24 months. The score of the JOA, NDI, VAS in the two groups of patients improved significantly after surgery than before surgery. In addition, the VAS score in last follow-up were significantly different between the two groups, but other index each time in the two groups showed no significant difference. In last follow-up, the result of artificial cervical disc arthroplasty group were better than ACDF group on the incidence of axial symptoms, the total cervical spine range of motion (ROM) and middle segments of motion. The incidence of axial symptoms in artificial cervical disc arthroplasty group were 11.1%,ACDF group were 45.2%. ROM in arti-ficial cervical disc arthroplasty group were 35.5°±5.9°,ACDF group were 24.5°±6.2°. Middle segments of motion in artificial cer-vical disc arthroplasty group were 7.3°±1.4°,ACDF group were 10.1°±1.6°. The above comparison of the datas were statistically different. There are two cases of adjacent segment degeneration in ACDF group without need to surgery

    2014-10-02

    In the previous decade, metal-on-metal hip resurfacing has been considered an attractive option and theoretically advantageous over conventional total hip arthroplasty, especially in young active patients. Different authors have reported favourable mid-term clinical and functional results with acceptable survival rates. Proper indication and planning, as accurate technical execution have been advocated to be crucial elements for success.Concerns regarding serum metal ion levels and possible clinical implications have led in the last years to a decline in the use of metal-on-metal hip resurfacing and metal-on-metal bearings in general.The aim of this study is to present the results of our first 486 cases of hybrid hip resurfacing arthroplasties with a second generation cementing technique, and to describe our current restricted indication of this type of prosthesis, in the light of recent findings in the literature about the possible complications related to metallosis or improper patient selection. Global survivorship of our series was 97.9% at a mean follow-up of 7.2 years.In the second season of our experience the indication is restrictive. The candidate for a resurfacing hip replacement is a young and active male patient, with good bone quality, that has been made aware of the risks and benefits of this type of prosthesis.

    Full Text Available Purpose: Arthroscopic transosseous (TO rotator cuff repair has recently emerged as a new option for surgical treatment of symptomatic rotator cuff tears. Limited data is available regarding outcomes using this technique. This study evaluated midterm clinical outcomes following a novel arthroscopic TO (anchorless rotator cuff repair technique. Materials and Methods: A consecutive series of 107 patients and 109 shoulders underwent arthroscopic TO (anchorless rotator cuff repair for a symptomatic full-thickness tear. Pre and postoperative range of motion (ROM was compared at an average of 11.8 months. Postoperative outcome scores were obtained at an average of 38.0 months. Statistical analysis was performed to compare pre and postoperative ROM data. Univariate analysis was performed using Student′s t-test to compare the effect of other clinical characteristics on final outcome. Results: Statistically significant improvements were noted in forward flexion, external rotation and internal rotation (P < 0.0001. Average postoperative subjective shoulder value was 93.7, simple shoulder test 11.6, and American Shoulder and Elbow Surgeons (ASES score 94.6. According to ASES scores, results for the 109 shoulders available for final follow-up were excellent in 95 (87.1%, good in 8 (7.3%, fair in 3 (2.8%, and poor in 3 (2.8%. There was no difference in ROM or outcome scores in patients who underwent a concomitant biceps procedure (tenodesis or tenotomy compared with those who did not. Furthermore, there was no significant difference in outcome between patients who underwent either biceps tenodesis or tenotomy. Age, history of "injury" preceding the onset of pain, tear size, number of TO tunnels required to perform the repair, and presence of fatty infiltration did not correlate with postoperative ROM or subjective outcome measures at final follow-up. Two complications and four failures were noted. Conclusions: Arthroscopic TO rotator cuff repair technique

  10. A financial indicator for mid-term tendencies

    Science.gov (United States)

    Leonel Caetano, Marco Antonio; Yoneyama, Takashi

    2007-11-01

    This work proposes an heuristic indicator for mid-term tendencies of stock prices based on non-linear dynamic equations combined with a graphical method inspired on cell morphology analysis. The model consists of ordinary differential equations with parameters that are fitted by means of the actual data history of stock prices using Extended Kalman Filter. The model structures are to be chosen so as to adequately represent the specific microeconomic condition, such as oligopoly with leader and follower, economic clusters, firms producing complementary products and others. The equations are solved numerically and the trajectories in the phase plane are associated with cell membranes. In an analogy with the increase in the cell volume when its internal pressure rises, the new financial indicator expresses the increase of the stress in a stock market by means of expanding phase portraits.

    Mitral valve repair to treat mitral regurgitation (MR) in pediatric patients remains challenging because of the complex morphology and fragility of the leaflets. The study aim was to review retrospectively the authors' experience with mitral valve repair using autologous pericardium. Between April 2004 and November 2011, nine pediatric patients (six males, three females; mean age 2.4 +/- 4.5 years) underwent mitral valve repair with an autologous fresh (n = 5) or glutaraldehyde-treated pericardium (n = 4) to treat severe MR. The etiology of the MR was acute endocarditis, acute chordal rupture and congenital disease in three, two, and four patients, respectively. Autologous pericardium was used for valvuloplasty, leaflet extension plasty and commissuroplasty in two, five, and two patients, respectively. Artificial chordal replacement was performed in three patients. No operative deaths or postoperative endocarditis occurred. One patient required mitral valve replacement at three days after the initial mitral repair. The most recent echocardiography findings of the remaining patients after a mean of 6.3 years (range: 1.3-9.0 years) showed that the severity of mitral insufficiency, left ventricular diastolic diameter and fractional shortening were 1.8 +/- 0.6 (grades 0-4), 40.4 +/- 8.4 mm (114.2 +/- 15.8% of normal) and 35.0 +/- 5.0%, respectively. Mitral valve repair using autologous fresh pericardium is associated with mid-term durability and resistance to infection when used for mitral valve repair of active endocarditis in pediatric patients. Augmentation with autologous pericardium could become an alternative to current surgical options.

    The complementary role of mitral valve repair versus replacement is based on evidence of long-term results in open surgery. Transcatheter mitral valve repair and replacement are both under rapid development but subject to clinical feasibility and first in-human short- and midterm outcome studies. The present article aims to review mitral valve repair and replacement by both techniques and to elucidate similar and potentially different aspects among the open and interventional approach.

  17. A New Comprehensive Final Exam

    2015-01-01

    Instructors aspire for students to master all the material covered. The final exam should assess the breadth and depth of their learning and be a significant basis for the final grade. I insist on a comprehensive final because I want students to review early material in light of later topics. I believe that this helps students create connections, integrate understanding, and retain knowledge for the long term. For non-science majors, reviewing and retaining the large amount of astronomy material is daunting. I experimented with a final exam format that calmed their fears and encouraged thorough review. It is only practical for a class of about twenty students or less. I provided a number of challenging conceptual and problem solving questions (at least as many as there were students), crafted to interconnect and span the entire range of topics. The order of the questions reflected the sequence in which the topics had been discussed. Students received these questions in ample time to prepare prior to the final. A student could bring up to 5 standard sheets of notes to the final. At the final, each student picked a number out of a hat. This was the question they had to answer in a 5-minute presentation. They were allowed 15 minutes for a final preparation during which they could use their 5 pages of notes. The presentations were given in order, 1- 20. Written comments on at least 10 other talks, explaining what was missed or correcting a mistake were required. They were graded both on their talk and on their comments. This format required students to be prepared for any question and encouraged interaction and communication while studying. Knowing the questions beforehand provided a guide to their studying as well as allayed their fears about what could be asked. The students also received guidance to what constituted a good answer, namely accuracy (correct scientific argument, appropriate facts, no irrelevant material), thoroughness (answered the complete questions

  18. Weekly Formative Exams and Creative Grading Enhance Student Learning in an Introductory Biology Course.

    2017-01-01

    First-year students often become discouraged during introductory biology courses when repeated attempts to understand concepts nevertheless result in poor test scores. This challenge is exacerbated by traditional course structures that impose premature judgments on students' achievements. Repeated testing has been shown to benefit student ability to recognize and recall information, but an effective means to similarly facilitate skill with higher-order problems in introductory courses is needed. Here, we show that an innovative format that uses a creative grading scheme together with weekly formative midterm exams produced significant gains in student success with difficult items requiring analysis and interpretation. This format is designed to promote tenacity and avoid discouragement by providing multiple opportunities to attempt demanding problems on exams, detailed immediate feedback, and strong incentives to retain hope and improve. Analysis of individual performance trajectories with heat maps reveals the diversity of learning patterns and provides rational means for advising students. © 2017 E. G. Bailey et al.

  19. Directed Replacement

    CERN Document Server

    Karttunen, L

    1996-01-01

    This paper introduces to the finite-state calculus a family of directed replace operators. In contrast to the simple replace expression, UPPER -> LOWER, defined in Karttunen (ACL-95), the new directed version, UPPER @-> LOWER, yields an unambiguous transducer if the lower language consists of a single string. It transduces the input string from left to right, making only the longest possible replacement at each point. A new type of replacement expression, UPPER @-> PREFIX ... SUFFIX, yields a transducer that inserts text around strings that are instances of UPPER. The symbol ... denotes the matching part of the input which itself remains unchanged. PREFIX and SUFFIX are regular expressions describing the insertions. Expressions of the type UPPER @-> PREFIX ... SUFFIX may be used to compose a deterministic parser for a ``local grammar'' in the sense of Gross (1989). Other useful applications of directed replacement include tokenization and filtering of text streams.

    Despite enthusiasm for metal-on-metal bearings, disappointing short- to mid-term outcomes has all but halted the use of this bearing articulation. This review presents mid-term results for the ReCap Magnum total hip replacement. This prospective study evaluated 79 ReCap/Magnum/Taperloc total hip replacements with mean follow-up of 7.1 (range 3.7-9.2) years. 43 were female and 36 male. Metal ions were measured and radiographic measurement included a 'margin of safety' angle to quantify risk of edge loading. When a clinical suspicion of adverse reaction to metal debris was present, patients had metal artefact reduction sequence MRI. Harris Hip Score and Oxford Hip Score evaluated functional outcome and SF-12 and EQ-5L-5D assessed quality of life at final follow-up. 7 hips were revised indicating 91.1% survivorship at 7.1 years. Postoperative Harris Hip Score and Oxford Hip Score significantly improved. Females and symptomatic patients predicted increased metal ions. Margin of safety correlated with postoperative Oxford Hip Score. Symptomatic hips and positive MRI showed reduced survivorship. Compared to more traditional bearings like metal or ceramic on polyethylene the overall outcome of this ReCap/Magnum/Taperloc study cohort is modest. It is felt that further failures will occur in this group therefore cautious interpretation of the results is justified given the potential for reduced survival outcomes.

    To assess midterm (3 years) clinical outcomes of transcatheter aortic valve implantation (TAVI) in Belgium using the Edwards SAPIEN valve or the Medtronic CoreValve transcatheter heart valve (THV). Medium and long term follow-up data of both THVs are still relatively scarce, although of great clinical relevance for a relatively new but rapidly expanding treatment modality. Therefore, reporting mid- and long term clinical outcome data, coming from large "real world" national registries, remains contributive. Between December 2007 and March 2012, 861 "real world" patients who were not candidates for surgical aortic valve replacement as decided by the local heart teams, underwent TAVI at 23 sites. Eleven sites exclusively used SAPIEN THV (n = 460), while 12 exclusively used CoreValve THV (n = 401). Differences in clinical outcomes by valve system were assessed, according to access route and baseline EuroSCORE risk profile (20%: high risk). Overall cumulative survival at 3 years was 51% for SAPIEN vs. 60% for CoreValve (P = 0.021). In transfemorally treated patients, SAPIEN and CoreValve had similar survival at 3 years for each of the baseline EuroSCORE cohorts (low risk: 72% vs. 76%, P = 0.45; intermediate risk: 62% vs. 59%, P = 0.94; high risk: 48% vs. 53%, P = 0.65). Cumulative midterm 3 year survival after transfemoral TAVI in "real world" patients refused for surgery with similar baseline EuroSCORE risk profile is not different between SAPIEN or CoreValve. © 2015 Wiley Periodicals, Inc.

  2. Modular Endoprostheses for Nonneoplastic Conditions: Midterm Complications and Survival

    Full Text Available The use of modular endoprostheses is a viable option to manage both tumor resection and severe bone loss due to nonneoplastic conditions such as fracture sequelae, failed osteoarticular grafts, arthroplasty revisions, and periprosthetic fractures. We sought to investigate both midterm complications and failures occurred in 87 patients who underwent a megaprosthetic reconstruction in a nonneoplastic setting. After a mean follow-up of 58 (1–167 months, overall failure-free survival was 91.5% at 1 year, 80% at 2 years, 71.6% at 5 years, and 69.1% at 5 and 10 years. There was no significant difference in the survival rate according to the diagnosis at the index procedure (p=0.921, nor to the reconstruction site (p=0.402. The use of megaprostheses in a postneoplastic setting did not affect survival rate in comparison with endoprosthetic reconstruction of pure nonneoplastic conditions (p=0.851. Perimegaprosthetic infection was the leading complication, occurring in 10 (11.5% patients and implying a megaprosthetic revision in all but one case. Physicians should consider these results when discussing with patients desired outcomes of endoprosthetic reconstructions of a nonneoplastic disease.

  3. A mid-term report for LS1

    2014-01-01

    As the LHC’s first long shutdown, LS1, enters its second calendar year, it’s a good time for a mid-term report on how things are progressing.    Towards the end of last year, I had the pleasure to go down to the LHC tunnel to witness the closure of the first of the machine’s sectors to be completed. As I write, three sectors are now closed up, with a fourth not far behind. These are important milestones, and you can follow progress in detail in the regular LS1 reports in the Bulletin. They show that we’re on schedule for physics to resume in about a year from now, but more than that, they are an important reminder of the LS1 motto: safety, quality, schedule. It is fantastic news that we are on schedule, and testimony to the rigour that went into the detailed and complex planning of all the work that had to be undertaken in LS1. But more important than the schedule is the fact that we’ve carried out the work safely and that the qualit...

    2013-04-01

    To address the question, compared to having hip replacement with latent revision, does Bernese periacetabular osteotomy (PAO) before primary hip replacement occupy a preferable treatment strategy for middle aged (aged 35-54 years) hip dysplasia patients? We assessed the mid-term functional outcome and survivorship of PAO in those patients. Forty-one hips in 36 patients at middle age at the time of surgery (mean age, 39.5 years; range, 35-47 years) were retrospectively identified out of a total PAO cohort of 315 patients. Eleven of the 41 PAO hips also underwent osteochondroplasty at the femoral head-neck junction. Radiographic parameters of lateral centre edge angle, anterior centre edge angle and hip joint medialisation were investigated using the Harris Hip Score (HHS). The average follow-up was 5.1 years (range, two to ten years). Radiographic parameters postoperatively improved into the normal range, whereas no progression was found from preoperative Tonnis osteoarthritis score. Forty hips survived at the last follow-up, with HHS Score improved from 63.7 to 88.4. Compared to the sole PAO group, both postoperative alpha angle and range of joint motion improved in the PAO combined with osteochondroplasty group. However, no difference in HHS score was found. Good survivorship and improved joint function were identified in middle-aged Chinese patients following PAO with or without osteochondroplasty. We prudently suggest PAO as an alternative strategy for treating DDH in those patients.

Burch colposuspension is still estimated as a ‘gold standard’ by the Cochrane Collaboration Group in the treatment of operative stress urinary incontinence (SUI Some urogynecologists agree with this statement, some argue that Burch colposuspension should no longer be used. Objective. The aim of this study was to evaluate mid-term effects and patient’s satisfaction with standardized modified colposuspension performed in one centre. Material and methods. Modified colposuspension was performed after standardization by 2 trained gynaecologists in 354 women. Data collected from 227 women were added to the final analysis of mid-term results. Average time from the operation to mid-term visit was 19 months (range 9–36 months. Results. At mid-term visit, 86.3% of patients were cured. There was no case of post-void urine residual over 100 ml. Pain near the operated region was reported by 1 woman from agricultural region. No one reported negative impact of modified colposuspension on sexual activity or dyspareunia. Conclusions. Modified colposuspension according to the E. Petri technique seems to be an operation that is safe and well-tolerated by women with preoperative stress urinary incontinence and paravaginal defect without urodynamic signs of ISD in mid-term observation.

    The aim of this retrospective, single institution study was to describe our 4-year experience with the endovascular repair of isolated iliac artery aneurysms. Between May 1997 and June 2001, 16 patients (15 males; mean age 64+/-9 years), were treated with covered stent grafts. Twelve of the endovascular procedures were performed under epidural and 4 under local anaesthesia. The percutaneous approach was employed in 13 cases and the femoral artery had to be exposed in 3 cases that demanded simultaneous revascularization of the peripheral circulation (n=2) or required a 16 F sheath to employ a Baxter Lifepath stent graft (n=1). The mean size of the iliac aneurysms was 4.5 cm (range 3.5 to 5.2 cm). Four aneurysms involved the hypogastric ostium in absence of any distal neck. All the patients underwent initially successful endovascular treatment of isolated iliac aneurysms and were followed from 3 to 52 months (mean 18 months). No procedural deaths and no acute or late graft thrombosis occurred. The perioperative complications included 1 dissection of the external iliac artery that required a further endovacular procedure and 1 case of endovascular leak fed to the hypogastric artery. A CT scan 4 months later showed spontaneous thrombosis of aneurysm and no further leakage. Two patients had undergone combinated femoro-popliteal arterial bypass. In our early clinical experience the use of self-expandable covered stent graft successful treated isolated iliac artery aneurysms. Endovascular repair is a safe and effective technique with good midterm results in patients at standard and high risk.

    This article focuses on esophageal replacement as a surgical option for pediatric patients with end-stage esophageal disease. While it is obvious that the patient׳s own esophagus is the best esophagus, persisting with attempts to retain a native esophagus with no function and at all costs are futile and usually detrimental to the overall well-being of the child. In such cases, the esophagus should be abandoned, and the appropriate esophageal replacement is chosen for definitive reconstruction. We review the various types of conduits used for esophageal replacement and discuss the unique advantages and disadvantages that are relevant for clinical decision-making.

    The authors of this commentary discuss the recently completed review of the current Medical College Admission Test (MCAT), which has been used since 1991, and describe the blueprint for the new test that will be introduced in 2015. The design of the MCAT exam reflects changes in medical education, medical science, health care delivery, and the needs of the populations served by graduates of U.S. and Canadian medical schools. The authors describe how balancing the ambitious goals for the new exam and the varying priorities of the testing program's many stakeholders made blueprint design complex. They discuss the tensions and trade-offs that characterized the design process as well as the deliberations and data that shaped the blueprint.The blueprint for the MCAT exam balances the assessment of a broad range of competencies in the natural, social, and behavioral sciences and critical analysis and reasoning skills that are essential to entering students' success in medical school. The exam will include four sections: Biological and Biochemical Foundations of Living Systems; Chemical and Physical Foundations of Biological Systems; Psychological, Social, and Biological Foundations of Behavior; and Critical Analysis and Reasoning Skills.The authors also offer recommendations for admission committees, advising them to review applicants' test scores, course work, and other academic, personal, and experiential credentials as part of a holistic admission process and in relation to their institutions' educational, scientific, clinical, and service-oriented goals.

    We performed aortic valve replacement in 24 patients aged over 70 with small calcified valves. The surgical management of such patients remains controversial as the extensive calcification compromises implantation. Hence, we used an ultrasonic debridement instrument to remove calcium and selected a small prosthesis with the largest possible orifice without enlargement of the aortic annulus. Echocardiography showed significant reductions in left ventricular mass index compared with preoperative values. Early and mid-term prognosis has been relatively good.

    There is increasing concern about the threat posed by oil spills to the coastal environment. This is reflected in the promulgation of various national and international standards among which are those that require companies whose activities involves oil spill risk, to have oil pollution emergency plans or similar arrangements for responding promptly and effectively to oil pollution incidents. Operational oceanography systems (OOS) that provide decision makers with oil spill trajectory forecasting, have demonstrated their usefulness in recent accidents (Castanedo et al., 2006). In recent years, many national and regional OOS have been setup focusing on short-term oil spill forecast (up to 5 days). However, recent accidental marine oil spills (Prestige in Spain, Deep Horizon in Gulf of Mexico) have revealed the importance of having larger prediction horizons (up to 15 days) in regional-scale areas. In this work, we have developed a methodology to provide probabilistic oil spill forecast based on numerical modelling and statistical methods. The main components of this approach are: (1) Use of high resolution long-term (1948-2009) historical hourly data bases of wind, wind-induced currents and astronomical tide currents obtained using state-of-the-art numerical models; (2) classification of representative wind field patterns (n=100) using clustering techniques based on PCA and K-means algorithms (Camus et al., 2011); (3) determination of the cluster occurrence probability and the stochastic matrix (matrix of transition of probability or Markov matrix), p_ij, (probability of moving from a cluster "i" to a cluster "j" in one time step); (4) Initial state for mid-term simulations is obtained from available wind forecast using nearest-neighbors analog method; (5) 15-days Stochastic Markov Chain simulations (m=1000) are launched; (6) Corresponding oil spill trajectories are carried out by TESEO Lagrangian transport model (Abascal et al., 2009); (7) probability maps are

    Full Text Available Introduction : Transcatheter aortic valve implantation (TAVI is a less invasive treatment option for elderly, high-risk patients with symptomatic severe aortic stenosis (AS than aortic valve replacement. More importantly, TAVI improves survival and quality of life as compared to medical treatment in inoperable patients. Aim: To assess early- and mid-term clinical outcomes after TAVI. Material and methods: All consecutive high-risk patients with severe symptomatic AS undergoing TAVI from November 2008 to August 2014 were enrolled. The clinical and procedural characteristics, as well as clinical outcomes including mortality during 12-month follow-up, were assessed. Results : A total of 101 consecutive patients underwent TAVI for native aortic valve stenosis (100%. Patients were elderly, with a median age of 81.0 (76.0–84.0 years, 60.4% were female and 83.2% presented with NYHA III/IV. Median baseline EuroSCORE I and STS scores were 14.0 (10.0–22.5% and 12.0 (5.0–24.0%, respectively. The main periprocedural and in-hospital complications were minor vascular complications, bleeding requiring blood transfusions, and the need for a permanent pacemaker. In-hospital, 30-day, 6-month and 12-month mortality rates were 6.9%, 10.9%, 15.8% and 17.8%, respectively. Conclusions : A mortality rate of < 20% after 12 months seems acceptable given the high-risk population enrolled.

    Transcatheter aortic valve replacement (TAVR) may offer extreme-aged patients a treatment alternative to surgical aortic valve replacement (SAVR). The objective of this study was to describe outcomes of TAVR in nonagenarians using transfemoral and alternative access techniques. In a retrospective review, we found 95 nonagenarians who underwent TAVR from September 2007 through February 2014 at Emory University using a balloon expandable valve: transfemoral (n = 66), transapical (n = 14), transaortic (n = 14), and transcarotid (n = 1). Morbidity and 30-day and midterm mortality were assessed. Kaplan-Meier plots were used to determine midterm survival rates. The mean age of the patients was 91.8 ± 1.8 years, and 49 (52%) were female. Postoperative morbidity included 1 patient (1%) each with stroke, myocardial infarction, pneumonia, and renal failure. The mean postoperative length of stay was 6.8 ± 5.1 days for all patients. Overall 30-day mortality was 3.2%, much less than The Society of Thoracic Surgeons predicted risk of mortality of 14.5% ± 7.3%. There were no deaths in the transfemoral patients, but there were 2 transapical deaths (14.3%) and 1 transaortic death (7.1%). The Kaplan-Meier estimate of median survival was 2.6 years. Extreme-aged nonagenarian patients may have excellent outcomes from TAVR at 30-day and midterm follow-up. Alternative access TAVR is associated with higher morbidity and mortality than transfemoral TAVR. Referral for TAVR of nonagenarians should not be precluded based on age alone.

    Recent research on long-term postmenopausal hormone replacement therapy (HRT) indicates a positive effect on both total mortality and morbidity. This has raised the question of widespread preventive long-term use of HRT. Possible side-effects and ideological issues related to preventive HRT have led to debate and uncertainty among health professionals, in the media, and in the population at large. In order to evaluate the level of knowledge about and attitudes towards HRT, a randomly selected group of 737 Norwegian women aged 16-79 was interviewed by the Central Bureau of Statistics. One in three women had received information about HRT in the last two years, mainly through weekly magazines and physicians. The proportion who answered the questions on knowledge correctly varied from 36% to 47%. Those who had been given information by a physician possessed accurate knowledge, had more positive attitudes towards HRT and were more willing to use HRT than women who had reviewed information through other channels. Women with a higher level of education were better informed and more knowledgeable than others, but were nevertheless more reluctant to use HRT than those who were less educated. The limited number of women who actually receive information on HRT, the low level of knowledge and the ambivalent attitudes toward HRT are a major challenge to the public health service.

    The historical mid-term results of conversion total hip arthroplasty (THA) are acceptable; however, the complication rates are high. In total, 39 patients (45 hips) from 2 institutions underwent conversion THA from 1993-2006 and were retrospectively evaluated. The mean age was 48.3 years, the mean follow-up time was 8.7 years, and the mean duration arthrodesis prior to conversion THA was 18.2 years. The outcomes included operative time, blood loss, leg-length discrepancy (LLD), thigh circumference, Harris Hip Score (HHS), complications, and radiographic evaluation. A total of 34 THAs were cemented, and 11 were uncemented. The mean operative time was 102 minutes, and the mean blood loss was 1019 ml. The mean HHS improved from 32.4 to 82.5 (pTrendelenburg gait (6), early haematoma that required surgical evacuation (5), dislocation (2), deep infection (1), and early aseptic loosening of the components (2). In conclusion, the functional results of the conversion THA using predominantly cemented components are good at mid-term follow-up; although the complication rates remain higher than a standard primary THA, aseptic loosening rates of the cemented components is low at mid-term follow-up.

    Full Text Available Background Comminuted radial head fractures are often associated with secondary injuries and elbow instability. Objectives The aim of this retrospective study was to evaluate how well the modular metallic radial head implant EVOLVE® prosthesis restores functional range of motion (ROM and stability of the elbow in acute care. Patients and Methods Eighty-five patients with comminuted radial head fractures and associated injuries received treatment with an EVOLVE® prosthesis between May 2001 and November 2009. Seventy-five patients were available for follow-up. On average, patients were followed for 41.5 months (33.0: 4.0 - 93.0. Outcome assessment was done on the basis of pain, ROM, strength, radiographic findings, and functional rating scores such as Broberg and Morrey, the Mayo elbow performance index (MEPI, and disabilities of the arm, shoulder and hand (DASH. Our study is currently the largest analysis of clinical outcome of a modular radial head replacement in the literature. Results Overall, there were 2 (2.7% Mason II fractures, 21 (28% Mason III fractures, and 52 (69.3% Mason IV fractures. Arbeitsgemeinschaft fur osteosynthesefragen (AO classification was also determined. Of the 85 patients in our study, 75 were available for follow-up. Follow-up averaged 41.5 months (range, 4 - 93 months.

    In this study, we retrospectively analyzed the outcomes of adults with bicuspid aortic valve (BAV) disease who underwent aortic valve reconstructive surgery (AVRS), consisting of replacement of the diseased BAV with 2 or 3 pericardial leaflets plus fixation of the sinotubular junction for accurate and constant leaflet coaptation. From December 2007 through April 2013, 135 consecutive patients (mean age, 49.2 ± 13.1 yr; 73.3% men) with symptomatic BAV disease underwent AVRS. Raphe was observed in 84 patients (62.2%), and the remaining 51 patients had pure BAV without raphe. A total of 122 patients (90.4%) underwent 3-leaflet reconstruction, and 13 (9.6%) underwent 2-leaflet reconstruction. Concomitant aortic wrapping with an artificial graft was performed in 63 patients (46.7%). There were no in-hospital deaths and 2 late deaths (1.5%); 6 patients (4.4%) needed valve-related reoperation. The 5-year cumulative survival rate was 98% ± 1.5%, and freedom from valve-related reoperation at 5 years was 92.7% ± 3.6%. In the last available echocardiograms, aortic regurgitation was absent or trivial in 116 patients (85.9%), mild in 16 (11.9%), moderate in 2 (1.5%), and severe in one (0.7%). The mean aortic valve gradient was 10.2 ± 4.5 mmHg, and the mean aortic valve orifice area index was 1.3 ± 0.3 cm(2)/m(2). The 3-leaflet technique resulted in lower valve gradients and greater valve areas than did the 2-leaflet technique. Thus, in patients with BAV, AVRS yielded satisfactory early and midterm results with low mortality rates and low reoperation risk after the initial procedure.

    Midterm-evaluation of a 5-year prospective clinical splitmouth-investigation on survival rate and long-term behavior of all-ceramic partial coverage restorations (PCRs) on molars. Pressed ceramic and CAD/CAM fabricated PCRs were compared. 80 vital molars of 25 patients were restored with all-ceramic PCRs (40 IPS e.max Press*[IP] and 40 ProCAD*[PC]). IP-PCRs were heat pressed following the lost-wax method. PC-PCRs were fabricated with Cerec 3** and Cerec InLab** CAD/CAM system (**Sirona Dental Systems, Bensheim, Germany). All PCRs were adhesively luted with a light-polymerizing composite (Syntac*/Tetric*) (*Ivoclar Vivadent, Schaan, Liechtenstein). Clinical reevaluations were performed at baseline and 13, 25, and 36 months after insertion of the PCRs according to the modified United States Public Health Services (USPHS) criteria. Absolute failures were demonstrated by Kaplan-Meier survival rate. After an observation time up to 3 years, survival rate of IP-PCRs was 100% and 97% for PC-PCRs due to one severe fracture. The PC-PCR had to be replaced after 9 months. Secondary caries and endodontic complications did not occur. Increased clinical service time resulted in significant decrease of marginal adaptation (p=0.031) and enhanced marginal discoloration (pceramic materials demonstrated significant deteriorations in color match (pceramic and CAD/CAM fabricated partial coverage restorations exhibited a reliable treatment option to restore larger defects in posterior teeth. Marginal degradation of the resin cement and deterioration of the all-ceramic materials during clinical function determine the clinical long-term performance of partial coverage restorations.

    To explore mid-term follow up results of distal fixation prosthesis in treating unstable intertrochanteric fractures in elderly patients. From May 2008 to March 2014,58 elderly patients with unstable intertrochanteric were treated with distal fixation prosthesis, among them, there were 15 males and 43 females aged from 75 to 87 years old with an average of 83.2 years old. Fracture were classified according to Evans classification, 39 cases were type I c and 19 cases were type I d. Surgical risk was evaluated before operation, 9 patients were performed total hip arthroplasty and 49 patients were performed prosthetic replacement hip joint function of patients with different age period, Evans classificaton, prothesis type, fixation method were evaluated respectively by using Harris score. Fifty-six patients were followed up from 13 to 36 months with an average of 21.6 months. Harris score was 83.51 ± 6.40, 5 cases got excellent results, 38 cases good and 13 cases moderate. Harris score of patients aged from 75 to 80 years old was 88.64 ± 2.35, 81.64 ± 6.40 in patients aged more than 80 years old, and had significant differences between two groups; Harris score in patients with type Evans I c was 83.64 ± 6.53, and 83.11 ± 6.08 in type Evans I d, while there was no significant differences between two groups. There was no obvious meaning in Harris score between patients with tension band (83.63 ± 6.15) and without tension band (82.41 ± 6.57). There was no significant meaning in Harris score between patients with normal distal fixation prosthesis (83.34 ± 6.43) and femoral moment reconstruction distal fixation prosthesis (83.92 ± 6.51). There was 1 patient occurred hip joint dislocation on the operative side and re-dislocation after manual reduction, then received open reduction.

    Irreversible electroporation (IRE) is a novel nonthermal tissue ablation technique by high current application leading to apoptosis without affecting extracellular matrix. Previous results of renal IRE shall be supplemented by functional MRI and differentiated histological analysis of renal parenchyma in a chronic treatment setting. Three swine were treated with two to three multifocal percutaneous IRE of the right kidney. MRI was performed before, 30 min (immediate-term), 7 days (short-term), and 28 days (mid-term) after IRE. A statistical analysis of the lesion surrounded renal parenchyma intensities was made to analyze functional differences depending on renal part, side and posttreatment time. Histological follow-up of cortex and medulla was performed after 28 days. A total of eight ablations were created. MRI showed no collateral damage of surrounded tissue. The highest visual contrast between lesions and normal parenchyma was obtained by T2-HR-SPIR-TSE-w sequence of DCE-MRI. Ablation zones showed inhomogeneous necroses with small perifocal edema in the short-term and sharp delimitable scars in the mid-term. MRI showed no significant differences between adjoined renal parenchyma around ablations and parenchyma of untreated kidney. Histological analysis demonstrated complete destruction of cortical glomeruli and tubules, while collecting ducts, renal calyxes, and pelvis of medulla were preserved. Adjoined kidney parenchyma around IRE lesions showed no qualitative differences to normal parenchyma of untreated kidney. This porcine IRE study reveals a multifocal renal ablation, while protecting surrounded renal parenchyma and collecting system over a mid-term period. That offers prevention of renal function ablating centrally located or multifocal renal masses.

    Percutaneous closure of paravalvular leakage is an alternative to surgery in high-risk patients, but its use has been limited by a lack of specific devices. More appropriate devices-like the Amplatzer Vascular Plug III-have recently been developed, but information about their efficacy and safety is still scarce. The objective of the present study was to assess the mid-term results of paravalvular leakage closure with this device. We analyzed the clinical and echocardiographic course both in-hospital and mid-term (13 [9] months) in a series of 20 consecutive patients (age, 68 years; logistic EuroSCORE, 29) with paravalvular leakage and attempted percutaneous closure. Closure was attempted for 23 leaks (17 mitral and 6 aortic) during 22 procedures in 20 patients. Implantation was successful in 87% of the leaks and the procedure was successful in 83%-with success being defined as a reduction in regurgitation of ≥ 1 degree. Survival at 1 year was 64.7% and survival free of the composite event of death/surgery was 58.8%. The degree of residual regurgitation was not associated with mortality but was associated with functional status. Survivors showed significant improvement in functional class. Percutaneous closure of leakage with the Amplatzer Vascular Plug III is safe and efficient in the mid-term. However, mortality among high-risk patients is high independently of the degree of residual regurgitation, indicating that these procedures are performed when heart disease has reached an advanced stage.

    Chase, Norma

    2012-02-01

    In a first experiment with using Mastering Physics in a first semester calculus-based course, homework and exam performance was tracked periodically during the semester. As expected, the use of novel technology (and its ability to track which students were persistently working at problem exercises) motivated many students to become more involved with work on assigned physics problems. Although there did appear to be a significant correlation between exam averages and homework scores in the upper half of the exam average distribution, individuals spanning the full range of exam averages (down to 45 percent) earned homework scores as high as those who had performed outstandingly well in exams. In this work, we present results and proposed plausible explanations for the apparent anomaly.

    Full Text Available We developed a web-based tool to provide students with access to old exam problems and solutions. By controlling the order in which students saw the problems, as well as their access to solutions, we obtained data about student learning by studying old exam problems. Our data suggest that in general students learn from doing old exam problems, and that having access to the problem solutions increases their learning. However, the data also suggest the depth of learning may be relatively shallow. In addition, the data show that doing old exam problems provides important formative assessment about the student’s overall preparedness for the exam and their particular areas of strength and weakness.

    Two laboratory and two randomized field experiments tested a psychological intervention designed to improve students' scores on high-stakes exams and to increase our understanding of why pressure-filled exam situations undermine some students' performance. We expected that sitting for an important exam leads to worries about the situation and its consequences that undermine test performance. We tested whether having students write down their thoughts about an upcoming test could improve test performance. The intervention, a brief expressive writing assignment that occurred immediately before taking an important test, significantly improved students' exam scores, especially for students habitually anxious about test taking. Simply writing about one's worries before a high-stakes exam can boost test scores.

    Purpose: As the landscape of learning and testing shifts toward a computer-based environment, a replacement for paper-based methods of studying is desirable. Using Microsoft Excel, a study tool was developed that allows the user to populate multiple-choice questions and then generate an interactive quiz session to answer them. Methods: The code for the tool was written using Microsoft Excel Visual Basic for Applications with the intent that this tool could be implemented by any institution with Excel. The base tool is a template with a setup macro, which builds out the structure based on user’s input. Once the framework is built, the user can input sets of multiple-choice questions, answer choices, and even add figures. The tool can be run in random-question or sequential-question mode for single or multiple courses of study. The interactive session allows the user to select answer choices and immediate feedback is provided. Once the user is finished studying, the tool records the day’s progress by reporting progress statistics useful for trending. Results: Six doctoral students at UTHSCSA have used this tool for the past two months to study for their qualifying exam, which is similar in format and content to the American Board of Radiology (ABR) Therapeutic Part II exam. The students collaborated to create a repository of questions, met weekly to go over these questions, and then used the tool to prepare for their exam. Conclusion: The study tool has provided an effective and efficient way for students to collaborate and be held accountable for exam preparation. The ease of use and familiarity of Excel are important factors for the tool’s use. There are software packages to create similar question banks, but this study tool has no additional cost for those that already have Excel. The study tool will be made openly available.

    Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved groups. In this study, we examined whether and to what extent the characteristics of instructor-generated tests impact the exam performance of male and female and middle/high- and low-socioeconomic status (SES) students enrolled in introductory biology courses. We collected exam scores for 4810 students from 87 unique exams taken across 3 yr of the introductory biology series at a large research university. We determined the median Bloom's level and the percentage of constructed-response questions for each exam. Despite controlling for prior academic ability in our models, we found that males and middle/high-SES students were disproportionately favored as the Bloom's level of exams increased. Additionally, middle/high-SES students were favored as the proportion of constructed-response questions on exams increased. Given that we controlled for prior academic ability, our findings do not likely reflect differences in academic ability level. We discuss possible explanations for our findings and how they might impact how we assess our students.

    We wanted to valuate the mid-term therapeutic results of percutaneous transhepatic balloon angioplasty for portal vein stenosis after liver transplantation. From May 1996 to Feb 2005, 420 patients underwent liver transplantation. Percutaneous transhepatic angioplasty of the portal vein was attempted in six patients. The patients presented with the clinical signs and symptoms of portal venous hypertension or they were identified by surveillance doppler ultrasonography. The preangioplasty and postangioplasty pressure gradients were recorded. The therapeutic results were monitored by the follow up of the clinical symptoms, the laboratory values, CT and ultrasonography. The overall technical success rate was 100%. The clinical success rate was 83% (5/6). A total of eight sessions of balloon angioplasty were performed in six patients. The mean pressure gradient decreased from 14.5 mmHg to 2.8 mmHg before and after treatment, respectively. The follow up periods ranged from three months to 64 months (mean period; 32 months). Portal venous patency was maintained in all six patients until the final follow up. Combined hepatic venous stenosis was seen in one patient who was treated with stent placement. One patient showed puncture tract bleeding, and this patient was treated with coil embolization of the right portal puncture tract via the left transhepatic portal venous approach. Percutaneous transhepatic balloon angioplasty is an effective treatment for the portal vein stenosis that occurs after liver transplantation, and our results showed good mid-term patency with using this technique.

    Full Text Available Laminoplasty is a standard technique for treating patients with multilevel cervical spondylotic myelopathy. Modified expansive open-door laminoplasty (MEOLP preserves the unilateral paraspinal musculature and nuchal ligament and prevents facet joint violation. The purpose of this study was to elucidate the midterm surgical outcomes of this less invasive technique. We retrospectively recruited 65 consecutive patients who underwent MEOLP at our institution in 2011 with at least 4 years of follow-up. Clinical conditions were evaluated by examining neck disability index, Japanese Orthopaedic Association (JOA, Nurick scale, and axial neck pain visual analog scale scores. Sagittal alignment of the cervical spine was assessed using serial lateral static and dynamic radiographs. Clinical and radiographic outcomes revealed significant recovery at the first postoperative year and still exhibited gradual improvement 1–4 years after surgery. The mean JOA recovery rate was 82.3% and 85% range of motion was observed at the final follow-up. None of the patients experienced aggravated or severe neck pain 1 year after surgery or showed complications of temporary C5 nerve palsy and lamina reclosure by the final follow-up. As a less invasive method for reducing surgical dissection by using various modifications, MEOLP yielded satisfactory midterm outcomes.

    To retrospectively analyze the early and the midterm results of endovascular management of aortoiliac obstructive disease with the kissing stent technique. From January 2005 to September 2012, 229 consecutive endovascular interventions for aortoiliac obstructive disease were performed; data from all the interventions were prospectively collected in a dedicated database. In 41 patients, the kissing stent technique at the level of aortic bifurcation was performed (group 1), whereas in the remaining 188 it was not (group 2). Perioperative results were compared with chi-squared test. Follow-up results were analyzed with Kaplan-Meier curves and compared with log-rank test. Trans-Atlantic Inter-Society Consensus II C and D lesions were present in 66% of patients in group 1 and in 28.5% in group 2 (P kissing stent technique provided satisfactory results in patients with obstructive aortoiliac diseases, without an increase in immediate and midterm complications, representing an effective solution in complex anatomies.

    2010-01-01

    Total ankle replacement (TAR) was first attempted in the 1970s, but poor results led to its being considered inferior to ankle fusion until the late 1980s and early 1990s. By that time, newer designs which more closely replicated the natural anatomy of the ankle, showed improved clinical outcomes.1 Currently, even though controversy still exists about the effectiveness of TAR compared to ankle fusion, TAR has shown promising mid-term results and should no longer be considered an experimental procedure. Factors related to improved TAR outcomes include: 1) better patient selection, 2) more precise knowledge and replication of ankle biomechanics, 3) the introduction of less-constrained designs with reduced bone resection and no need for cementation, and 4) greater awareness of soft-tissue balance and component alignment. When TAR is performed, a thorough knowledge of ankle anatomy, pathologic anatomy and biomechanics is needed along with a careful pre-operative plan. These are fundamental in obtaining durable and predictable outcomes. The aim of this paper is to outline these aspects through a literature review. PMID:21045984

  1. Evaluating multiple-choice exams in large introductory physics courses

    Directory of Open Access Journals (Sweden)

    Gary Gladding

    2006-07-01

    Full Text Available The reliability and validity of professionally written multiple-choice exams have been extensively studied for exams such as the SAT, graduate record examination, and the force concept inventory. Much of the success of these multiple-choice exams is attributed to the careful construction of each question, as well as each response. In this study, the reliability and validity of scores from multiple-choice exams written for and administered in the large introductory physics courses at the University of Illinois, Urbana-Champaign were investigated. The reliability of exam scores over the course of a semester results in approximately a 3% uncertainty in students’ total semester exam score. This semester test score uncertainty yields an uncertainty in the students’ assigned letter grade that is less than 1 / 3 of a letter grade. To study the validity of exam scores, a subset of students were ranked independently based on their multiple-choice score, graded explanations, and student interviews. The ranking of these students based on their multiple-choice score was found to be consistent with the ranking assigned by physics instructors based on the students’ written explanations ( r>0.94 at the 95% confidence level and oral interviews (r=0.94−0.09+0.06 .

    LeMoine, Dana M; Bergdall, Valerie K; Freed, Carrie

    2015-05-01

    Aseptic technique includes the use of sterile surgical gloves for survival surgeries in rodents to minimize the incidence of infections. Exam gloves are much less expensive than are surgical gloves and may represent a cost-effective, readily available option for use in rodent surgery. This study examined the effectiveness of surface disinfection of exam gloves with 70% isopropyl alcohol or a solution of hydrogen peroxide and peracetic acid (HP-PA) in reducing bacterial contamination. Performance levels for asepsis were met when gloves were negative for bacterial contamination after surface disinfection and sham 'exertion' activity. According to these criteria, 94% of HP-PA-disinfected gloves passed, compared with 47% of alcohol-disinfected gloves. In addition, the effect of autoclaving on the integrity of exam gloves was examined, given that autoclaving is another readily available option for aseptic preparation. Performance criteria for glove integrity after autoclaving consisted of: the ability to don the gloves followed by successful simulation of wound closure and completion of stretch tests without tearing or observable defects. Using this criteria, 98% of autoclaved nitrile exam gloves and 76% of autoclaved latex exam gloves met performance expectations compared with the performance of standard surgical gloves (88% nitrile, 100% latex). The results of this study support the use of HP-PA-disinfected latex and nitrile exam gloves or autoclaved nitrile exam gloves as viable cost-effective alternatives to sterile surgical gloves for rodent surgeries.

    Arsan, Taner; Saka, Hamit Emre; Sahin, Ceyhun

    This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. The implemented system has basic specifications such as appending questions in system, building exams with these appended questions and making students to take these exams. There are three different types of users with different authorizations. These are system administrator, operators and students. System administrator operates and maintains the system, and also audits the system integrity. The system administrator can not be able to change the result of exams and can not take an exam. Operator module includes instructors. Operators have some privileges such as preparing exams, entering questions, changing the existing questions and etc. Students can log on the system and can be accessed to exams by a certain URL. The other characteristic of our system is that operators and system administrator are not able to delete questions due to the security problems. Exam questions can be inserted on their topics and lectures in the database. Thus; operators and system administrator can easily choose questions. When all these are taken into consideration, FLEX software provides opportunities to many students to take exams at the same time in safe, reliable and user friendly conditions. It is also reliable examination system for the authorized aviation administration companies. Web development platform - LAMP; Linux, Apache web server, MySQL, Object-oriented scripting Language - PHP are used for developing the system and page structures are developed by Content Management System - CMS.

    Patients with coarctation of the aorta can be treated either with surgery or with balloon angioplasty. So far, the last method has proved to be successful in children, but results of this treatment in (young) adults are virtually unknown. The aim of this study was to evaluate the immediate and mid-term follow-up results of balloon angioplasty of native coarctation in (mainly young) adults. Coarctation of the aorta was diagnosed by means of ultrasound or angiography, and defined as a stenosis with a pressure gradient greater than 20 mm Hg. The balloon angioplasty-procedure was carried out under complete anesthesia, and was considered to be successful, if the pressure gradient was reduced to less than 20 mm Hg. Nineteen consecutive adults (12 males, 7 females; aged 14-67 years, median 29) with native coarctation were treated from 1995-99. Mean pressure gradient decreased from 49.3+/- 20.8 to 4.8+/-8.2 mm Hg (P<0.0001). One patient showed a suboptimal result with a residual pressure gradient of 28 mm Hg. In one other patient a stent was placed on request of the referring physician. Follow-up was 100% complete and ranged from 3-47 months (mean 20.2+/- 12.9). At 1-year follow-up mean systolic blood pressure was reduced from 159.4+/-19.5 to 132.5+/-17.6 mm Hg (n = 18; P<0.0001), and mean ankle-arm pressure index improved from 0.73+/-0.09 to 0.96+/-0.05 (n = 18; P<0.0001). Anti-hypertensive medication could either be reduced or stopped in 7 patients (53.8%). With ultrasound or angiography or MRI, no patients had signs of aneurysm formation or worsening restenosis during follow-up. In adult patients with uncomplicated native coarctation of the aorta, balloon angioplasty (without stenting) would seem to be an excellent and safe alternative for surgery. In our hospital it has completely replaced surgical correction in such patients.

    Surgical pulmonary embolectomy has been used for the successful treatment of massive and submassive pulmonary emboli. The purpose of this study is to document the short- and midterm echocardiographic follow-up of right ventricular function after surgical pulmonary embolectomy for acute pulmonary embolus. A retrospective review of the local Society of Thoracic Surgeons database of patients who underwent surgical pulmonary embolectomy for acute pulmonary embolectomy was conducted from 1998 to 2014 at a US academic center. Patients with chronic thrombus were excluded. The institutional echocardiographic database was searched for follow-up studies to compare markers of right ventricular function. Unadjusted outcomes were described, and quantitative comparisons were made of short- and long-term echocardiographic data. A total of 44 patients were included for analysis; 35 patients (79.5%) had a submassive pulmonary embolectomy, and 9 patients (20.5%) had a massive pulmonary embolectomy and required preoperative inotropy. Mean cardiopulmonary bypass time was 68.0 ± 40.2 minutes, and 30 patients (68.2%) underwent procedures without aortic crossclamping. There was 1 in-hospital mortality (2.3%), and there were no permanent neurologic deficits. A total of 21 patients had echocardiography results available for follow-up. Perioperative echocardiographic data showed an immediate decrease in tricuspid regurgitant velocity and right ventricular pressure (P < .05). Mean midterm echocardiographic follow-up was 30 months in 12 patients. At midterm follow-up, improvements in right ventricular function observed postoperatively persisted. Only 1 patient had moderate right ventricular dysfunction, and no patient had worse than mild tricuspid regurgitation. Mean tricuspid valve regurgitant velocity was 2.4 ± 0.7 m/s, and mean pulmonary artery systolic pressure was 37.2 ± 14.2 mm Hg. Surgical pulmonary embolectomy may represent optimal therapy in selected patients for

    1978-07-27

    The general objective of the Near-Term Electric Vehicle Program is to confirm that, in fact, the complete spectrum of requirements placed on the automobile (e.g., safety, producibility, utility, etc.) can still be satisfied if electric power train concepts are incorporated in lieu of contemporary power train concepts, and that the resultant set of vehicle characteristics are mutually compatible, technologically achievable, and economically achievable. The focus of the approach to meeting this general objective involves the design, development, and fabrication of complete electric vehicles incorporating, where necessary, extensive technological advancements. A mid-term summary is presented of Phase II which is a continuation of the preliminary design study conducted in Phase I of the program. Information is included on vehicle performance and performance simulation models; battery subsystems; control equipment; power systems; vehicle design and components for suspension, steering, and braking; scale model testing; structural analysis; and vehicle dynamics analysis.

    2008-01-01

    The paper shows that there exists a strong interrelation between the two examined aspects of long-term and mid-term mobility. The residential mobility is influenced by the ownership of the different mobility tools, and vice versa. Thereby the mobility tool ownership remains comparably stable over longer periods of time. Concerning the ownership of the various mobility tools, the analyses indicate that car ownership and public transport season ticket ownership substitute one another. During the life course car ownership is highest among those who are 35 to 55 years old today. At the same time, men have noticeably more frequently a car at their disposal than women of the same age. Concerning the ownership of national and regional season tickets, the opposite trend is visible.

A computable general equilibrium model coupled with a land-based mitigation technology model was used to evaluate specific mitigation options within the whole economic framework. The results revealed three primary findings: (1 If no climate policy were implemented, Indonesia’s total greenhouse gas emissions would reach 3.0 GtCO2eq by 2030; (2 To reduce carbon emissions to meet the latest Intended Nationally-Determined Contributions (INDC target, ~58% of total reductions should come from the agriculture, forestry and other land use sectors by implementing forest protection, afforestation and plantation efforts; (3 A higher carbon price in 2020 suggests that meeting the 2020 target would be economically challenging, whereas the INDC target for 2030 would be more economically realistic in Indonesia.

    1993-01-01

    This paper presents some improvements in the methodology for analysing mid-term dynamic processes in power systems. These improvements are: an efficient application of the hierarchical clustering algorithm to adaptive identification of coherent generator groups and a significant reduction of the mathematical model, on the basis of monitoring the state of only one generator in one of the established coherent groups. This enables a flexible, simple and fast transformation from the full to the reduced model and vice versa, a significant acceleration of the simulation while keeping the desired accuracy and the automatic use in continual dynamic analysis. Verification of the above mentioned contributions was performed on examples of the dynamic analysis of New England and Yugoslav power systems. (author)

  4. Effects of Apophenia on Multiple-Choice Exam Performance

    Directory of Open Access Journals (Sweden)

    Stephen T. Paul

    2014-11-01

    Full Text Available There is a broad literature on the various issues related to effective exam construction applicable to both on-ground and online course delivery. These guidelines tend to support rather close contact between the instructor and the exam. However, to remain competitive, both textbook and course management providers have developed technologies to automate many aspects of exam construction. As test construction becomes automated, the possibility of inadvertently deviating from demonstrated or intuitive guidelines increases. Two experiments were conducted to examine the degree to which apophenia (perceiving patterns in random data might negatively influence multiple-choice exam performance among college students. Experiment 1 indirectly demonstrated the extent to which certain answer patterns seemed to be tolerated among students (maximum of three repeated answers in comparison with what might be expected from randomly generated exams from Blackboard. Experiment 2 directly examined the effects of answer patterns on exam performance. Participants’ performance declined as the underlying answer patterns became more obvious, and this effect appeared to be particularly strong for the upper level psychology students. The importance and implications of these findings with regard to automated test construction were discussed, and a recommendation is provided.

  5. Does Question Structure Affect Exam Performance in the Geosciences?

    Day, E. A.; D'Arcy, M. K.; Craig, L.; Streule, M. J.; Passmore, E.; Irving, J. C. E.

    2015-12-01

    The jump to university level exams can be challenging for some students, often resulting in poor marks, which may be detrimental to their confidence and ultimately affect their overall degree class. Previous studies have found that question structure can have a strong impact on the performance of students in college level exams (see Gibson et al., 2015, for a discussion of its impact on physics undergraduates). Here, we investigate the effect of question structure on the exam results of geology and geophysics undergraduate students. Specifically, we analyse the performance of students in questions that have a 'scaffolded' framework and compare them to their performance in open-ended questions and coursework. We also investigate if observed differences in exam performance are correlated with the educational background and gender of students, amongst other factors. It is important for all students to be able to access their degree courses, no matter what their backgrounds may be. Broadening participation in the geosciences relies on removing systematic barriers to achievement. Therefore we recommend that exams are either structured with scaffolding in questions at lower levels, or students are explicitly prepared for this transition. We also recommend that longitudinal studies of exam performance are conducted within individual departments, and this work outlines one approach to analysing performance data.

  6. Crib sheets and exam performance in a data structures course

    2016-01-01

    In this paper, we study the relationship between the use of "crib sheets" or "cheat sheets" and performance on in-class exams. Our extensive survey of the existing literature shows that it is not decisive on the questions of when or whether crib sheets actually help students to either perform better on an exam or better learn the material. We report on our own detailed analysis for a body of crib sheets created for the final exam in a junior-level Data Structures and Algorithms course. We wanted to determine whether there is any feature of the crib sheets that correlates to good exam scores. Exam performance was compared against a number of potential indicators for quality in a crib sheet. We have found that students performed significantly better on questions at the comprehension level of Bloom's taxonomy when their crib sheet contained good information on the topic, while performance on questions at higher levels of the taxonomy did not show correlation to crib sheet contents. We have also seen that students at certain levels of performance on the final exam (specifically, medium-to-high performance) did relatively better on certain questions than other students at that performance level when they had good coverage of that question's topic on their crib sheet.

    It has been postulated that video-assisted thoracoscopic surgery (VATS) achieves a better biometric and aesthetic outcome than conventional thoracic surgery (CTS), but data are lacking. We aimed to compare the midterm effects of both approaches in children. Sixty-two infants and children, who underwent VATS (34; 55%) or CTS (28; 45%) for benign thoracic conditions, were evaluated at follow-up after a mean of 3.8 years (1 to 7 years). The patients underwent standardized clinical assessment of the skeletal system and function. The intercostal spaces were investigated for rib fusion by ultrasound. Patients (+/- parents) themselves, as well as clinicians, subsequently assessed the scars. Comparing the operated versus nonoperated sides, chest asymmetry was significantly less frequent after VATS versus CTS in the horizontal plane (mean relative difference 0.996 +/- 0.003 vs 0.964 +/- 0.008, p joints did not differ significantly. However, the incidence of scoliosis was lower in VATS patients (9% vs 54%, p intercostal spaces of the operated hemithoraces were narrower after CTS (p < 0.001). The Manchester scar assessment scores were in favor of VATS (mean 7.5 vs 13.1, p < 0.001). The visual analog scale scores recorded by patients-parents and independent observers were also significantly better after VATS. Patient satisfaction was less with CTS as 10% wanted to have the scar revised, compared with none in the VATS group. The thoracoscopic versus conventional approach to the thoracic cavity in children is associated with significantly less midterm musculoskeletal sequelae and a better cosmetic outcome.

    We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students' dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students' grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p=.01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R=0.1, p=.01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain.

  14. Diagnosis of Alzheimer's disease in Brazil: Supplementary exams

    Directory of Open Access Journals (Sweden)

    Paulo Caramelli

    Full Text Available Abstract This article presents a review of the recommendations on supplementary exams employed for the clinical diagnosis of Alzheimer's disease (AD in Brazil published in 2005. A systematic assessment of the consensus reached in other countries, and of articles on AD diagnosis in Brazil available on the PUBMED and LILACS medical databases, was carried out. Recommended laboratory exams included complete blood count, serum creatinine, thyroid stimulating hormone (TSH, albumin, hepatic enzymes, Vitamin B12, folic acid, calcium, serological reactions for syphilis and serology for HIV in patients aged younger than 60 years with atypical clinical signs or suggestive symptoms. Structural neuroimaging, computed tomography or - preferably - magnetic resonance exams, are indicated for diagnostic investigation of dementia syndrome to rule out secondary etiologies. Functional neuroimaging exams (SPECT and PET, when available, increase diagnostic reliability and assist in the differential diagnosis of other types of dementia. The cerebrospinal fluid exam is indicated in cases of pre-senile onset dementia with atypical clinical presentation or course, for communicant hydrocephaly, and suspected inflammatory, infectious or prion disease of the central nervous system. Routine electroencephalograms aid the differential diagnosis of dementia syndrome with other conditions which impair cognitive functioning. Genotyping of apolipoprotein E or other susceptibility polymorphisms is not recommended for diagnostic purposes or for assessing the risk of developing the disease. Biomarkers related to the molecular alterations in AD are largely limited to use exclusively in research protocols, but when available can contribute to improving the accuracy of diagnosis of the disease.

    Cossetto, David J; Goudar, Anil

    2012-12-01

    To report the mid-term outcome of a modular, cementless, proximally hydroxyapatitecoated, anatomic femoral stem in total hip arthroplasty (THA). 160 consecutive patients aged 42 to 92 (mean, 70) years underwent 185 cementless THAs for primary osteoarthritis or femoral neck fractures. All procedures were performed by a single surgeon using the same modular, cementless, proximally hydroxyapatite-coated, anatomic femoral stem, regardless of age and bone quality. Clinical evaluation (pain, range of movement, and ability to walk) was based on the Merle d'Aubigne and Postel scores. Radiological assessment was based on criteria by Engh et al. in the 7 Gruen zones with regard to the presence of radiolucent lines, osteolysis, cancellous condensation, cortical hypertrophy or atrophy, reactive lines, and pedestal formation. Failure of the stem was defined as revision or impending revision because of aseptic loosening or pain. Of the 160 patients, 21 died and none were lost to follow-up. In 3 of the 21 patients, the femoral stems were revised for periprosthetic fractures after a fall at 6 weeks, 10 months, and 3.8 years. 138 patients (162 THAs) completed a mean follow-up of 7.8 (range, 5.5-10.4) years. Their overall mean Merle d'Aubigne and Postel scores increased from 7.09 preoperatively to 16.36 postoperatively. The mean Engh score was 24.9 out of 27, with the mean score for femoral stem fixation 10 out of 10 and 14.9 out of 17 for femoral stem stability. No reactive lines at the bone-stem interfaces and no subsidence or osteolysis were evident in any of the radiographs. There were 5 periprosthetic femoral fractures, 2 deep infections, 3 dislocations, and 2 aseptic loosening (one each for the femoral stem and acetabular socket). Survivorship of the femoral stem at 10 years was 99% when revision secondary to only aseptic loosening of the stem was the endpoint. It was 96% when failures due to all causes (infection, periprosthetic fracture, and aseptic loosening) were the

    Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient

    2015-10-01

    While the authors were doing a test period of databases, the question of whether or not databases affect outcomes of graduate nursing comprehensive examinations came up. This study explored that question through using citation analysis of exams that were taken during a database trial and exams that were not. The findings showed no difference in examination pass/fail rates. While the pass/fail rates did not change, a great deal was learned in terms of citation accuracy and types of materials that students used, leading to discussions about changing how citation and plagiarism awareness were taught.

    2014-02-01

    The early diagnosis of necrotizing fasciitis is often ambiguous. Computed tomography and magnetic resonance imaging, while sensitive and specific modalities, are often time consuming or unavailable. We present a case of necrotizing fasciitis that was rapidly diagnosed using bedside ultrasound evaluating for subcutaneous thickening, air, and fascial fluid (STAFF). We propose the STAFF ultrasound exam may be beneficial in the rapid evaluation of unstable patients with consideration of necrotizing fasciitis, in a similar fashion to the current use of a focused assessment with sonography for trauma exam in the setting of trauma.

  8. Importance of a midterm time horizon for addressing ethical issues integral to nanobiotechnology.

    Science.gov (United States)

    Khushf, George

    2007-01-01

    There is a consensus emerging on the importance of upstream ethical engagement in nanobiotechnology. Such a preventive ethic would anticipate downstream concerns that might arise and mitigate them as part of the research and development process. However, there is an unappreciated tension between the time horizon of upstream ethics and that assumed by most bioethical research. Current standards of high-quality research on ethical issues biases the research in favor of near-term, science-based, results-oriented work. A near-term focus would miss many of the important ethical issues integral to nanobiotechnology and undermine the goals integral to upstream ethical engagement. However, if we move to a far-term time horizon, the ethical debates tend to get too speculative and are no longer disciplined by existing research trajectories. This paper addresses the link between the midterm time horizon necessary for upstream ethics and the form, content, and style of ethical reflection. New paradigm cases, standards, and criteria will be needed for high-quality upstream ethics work in the area of nanobiotechnology.

    The purpose of this retrospective, single-institution study is to describe a 4-year experience of examining early and late clinical outcomes after endovascular repair of abdominal aortic aneurysm (AAA). Between October 1998 and January 2003, 455 patients were submitted for AAA treatment, of whom 269 underwent open repair and 186 were treated with an endovascular procedure. All endovascular-treated patients underwent preoperative arteriography, contrast enhanced CT scanning or spiral-CT to define the morphological characteristics of the aneurysm, including precise diameter and length measurements. Technical success was achieved in 182 (98%) of the endovascular procedures, as intraoperative conversions to open repair and/or aborted procedures occurred in four patients. The perioperative (30-day) mortality rate was 1% (two patients). During the follow-up period (9-60 months) CT, duplex ultrasound scanning and plain abdominal X-ray evaluation were performed at 3, 6, 12 months, and annually thereafter. Type I endoleak occurred in 12 patients (6.6%), required a further endovascular procedure (11) or late conversion to open repair (1). Type II endoleak occurred in five patients (3%). In our clinical experience the endovascular repair of AAA is a safe and effective technique with good mid-term results in patients at standard and high risk.

    2015-01-01

    Full Text Available A hybrid search algorithm consisting of three stages is presented to solve the midterm schedule for thermal power plants (MTSFTPP problem, where the primary objective is to achieve equal accumulated operating hours of installed capacity (EAOHIC for all thermal power plants during the selected period. First, feasible spaces are produced and narrowed based on constraints on the number of units and power load factors. Second, an initial feasible solution is obtained by a heuristic method that considers operating times and boundary conditions. Finally, the progressive optimality algorithm (POA, which we refer to as the vertical search algorithm (VSA, is used to solve the MTSFTPP problem. A method for avoiding convergence to a local minimum, called the lateral search algorithm (LSA, is presented. The LSA provides an updated solution that is used as a new feasible starting point for the next search in the VSA. The combination of the LSA and the VSA is referred to as the hybrid search algorithm (HSA, which is simple and converges quickly to the global minimum. The results of two case studies show that the algorithm is very effective in solving the MTSFTPP problem accurately and in real time.

    Full Text Available The aim of the study was to evaluate the mid-term clinical results and survivorship of a rotating-hinge knee prosthesis (LINK® Endo-Model in difficult primary and complex revision situations. Results after primary implantation were compared with those of revision procedures. Forty-nine prostheses in 45 patients were reviewed clinically during follow up. Twenty-one of these were implanted in primary and 28 in revision situations. Outcome was evaluated using commonly used scores (Knee Society, UCLA Activity, Lequesne and a visual analog scale after a mean follow up of 56±37 months for 49 prostheses. Implant survival was analyzed using the Kaplan-Meier method. There were no significant differences in clinical examination and evaluation scores between the two groups (P>0.05. Survival rates at final follow up were 95% after primary implantation and 76% in revision procedures. The risk of prosthesis loss (odds ratio 5.7 was significantly higher after revision procedures (P=0.004. These data suggest that rotating-hinge knee prostheses provided good clinical and functional results in selected cases of advanced primary gonarthrosis associated with severe bone loss, ligamentous instability or comminuted fractures. They also provide good results in revision situations. However, the failure rate was significantly higher in cases of revision surgery.

    Full Text Available OBJECTIVE: To review the presentation and outcome of developmental dysplasia of the hip (DDH cases in the last 6 years. METHODOLOGY: We retrospectively reviewed the presentation as well as short and mid-term outcome of 17 children (18 hips with DDH seen and treated from 2004 to 2010. Treatment was either splinting with Pavlik harness, closed or open reduction depending on age at presentation and the individual needs of each patient. RESULTS: The average age at presentation was 31.1 months, and the male to female ratio was 1:4.6. Six patients (35% presented early (less than 6 months old while 7 patients (41% presented between 6 -24 months. In these 2 groups splinting or closed reduction under anaesthesia was initially utilized for treatment depending on age, and open reduction was used after failure of closed reduction and for those presented late. Average age at the time of closed reduction was 11 months, and 6 years for those underwent open reduction. The average period of follow up for all patients was 29.4 months. The final outcome was successful in 12 hips (66% in 11 patients. Ten of these presented at less than 2 years old, in the other 6 hips in which there was failure, 50% presented after 3 years of age. CONCLUSION: Late presentation of DDH is still common in Malaysia, which necessitates more complex management and more frequent occurrences of unfavourable results.

    To analyze mid-term neurodevelopment outcome in children with isolated mild ventriculomegaly (VM) ≤12 mm diagnosed in fetal life, using the Battelle Developmental Inventory Screening Test (BDIST). 86 cases of mild VM were identified. 68 were excluded due to: other cerebral anomalies (n = 40), extra-cerebral anomalies (n = 3), chromosomal defects (n = 4), dysmorphic syndromes (n = 4), congenital infections (n = 2), termination of pregnancy (n = 9), stillbirth (n = 2) and incomplete follow-up (n = 4). 18 cases (range 1-8 years) of isolated mild VM were included for analysis. Seven neurodevelopment domains were assessed by BDIST. Routine neuropediatrical evaluation detected neurological disorders in five children (28%; 3 with language impairment, one left hemiparesis and one intellectual retardation). BDIST showed some degree of neurodevelopmental delay in higher proportions: 66% in social-personal skills, 56% in gross motor skills, 39% in adaptive behavior and 28% in fine motor skills. Communicative and cognitive areas were the least affected (11 and 22% had moderate-to-severe involvement, respectively). A general trend towards worse outcomes was observed in the group of ≥4 years, although significant differences were only found for gross motor skills. Subtle neurological delays may appear during the infant period in fetuses prenatally diagnosed of isolated mild VM. In consequence, adequate measures should be established for early detection and treatment. Copyright © 2011 S. Karger AG, Basel.

    In year 2000 the Danish Parliament decided to fund a four-year particle research programme, which should include characterization of physical and chemical properties of the particles in Denmark and their sources and also assess the adverse health effects and the socio-economic impact in the Danish society. The overall objective of the particle programme is to provide new and broader knowledge in Denmark on the health effect of atmospheric particles with the aim to develop strategies to reduce the adverse health effect of man-made and natural sources. The activities should be closely related to other activities in Denmark and internationally. Specifically National Environmental Research Institute (NERI) shall investigate emissions, size distributions, chemical composition, transformation and dispersion of particles. The present report is the mid-term report on the activities at NERI, and is a summary oef the experimental results, analysis of particle in relation to sources - especially road traffic - and the papers published in connection with the programme.

    Full Text Available Abstract Acromioclavicular joint dislocations often occur in athletic, young patients after blunt force to the shoulder. Several static and dynamic operative procedures with or without primary ligament replacement have been described. Between February 2003 and March 2009 we treated 313 patients suffering from Rockwood III-V lesions of the AC joint with an AC-hook plate. 225 (72% of these patients could be followed up. Mean operation time was 42 minutes in the conventional group and 47 minutes in the minimal invasive group. The postoperative pain on a scale from 1 to 10 (VAS-scale was rated 2.7 in the conventional group and 2.2 in the minimal invasive group. Taft score showed very good and good results in 189 patients (84%. Constant score showed an average of 92.4 of 100 possible points with 89% excellent and good results and 11% satisfying results. All patients had some degree of pain or discomfort with the hookplate in place. These symptoms were relieved after removal of the plate. The overall complication rate was 10.6%. There were 6 superficial soft tissue infections, 1 fracture of the acromion, 7 redislocations after removal of the hook-plate. We observed 4 broken hooks which could be removed at the time of plate removal, 4 seromas and 2 cases of lateral clavicle bone infection, which required early removal of the plate. We can conclude that clavicle hook plate is a convenient device for the surgical treatment of Rockwood Grade III-V dislocations, giving good mid-term results with a low overall complication rate compared to the literature. Early functional therapy is possible and can avoid limitations in postoperative shoulder function.

    Full Text Available Introduction: The purpose of this study is to describe an approach for evaluating assessments used in the first 2 years of medical school and report the results of applying this method to current first and second year medical student examinations. Methods: Three faculty members coded all exam questions administered during the first 2 years of medical school. The reviewers discussed and compared the coded exam questions. During the bi-monthly meetings, all differences in coding were resolved with consensus as the final criterion. We applied Moore's framework to assist the review process and to align it with National Board of Medical Examiners (NBME standards. Results: The first and second year medical school examinations had 0% of competence level questions. The majority, more than 50% of test questions, were at the NBME recall level. Conclusion: It is essential that multiple-choice questions (MCQs test the attitudes, skills, knowledge, and competency in medical school. Based on our findings, it is evident that our exams need to be improved to better prepare our medical students for successful completion of NBME step exams.

  15. The String Stability of a Trajectory-Based Interval Management Algorithm in the Midterm Airspace

    Science.gov (United States)

    Swieringa, Kurt A.

    2015-01-01

    NASA's first Air Traffic Management (ATM) Technology Demonstration (ATD-1) was created to facilitate the transition of mature ATM technologies from the laboratory to operational use. The technologies selected for demonstration are the Traffic Management Advisor with Terminal Metering (TMA-TM), which provides precise time-based scheduling in the terminal airspace; Controller Managed Spacing (CMS), which provides terminal controllers with decision support tools enabling precise schedule conformance; and Interval Management (IM), which consists of flight deck automation that enables aircraft to achieve or maintain a precise spacing interval behind a target aircraft. As the percentage of IM equipped aircraft increases, controllers may provide IM clearances to sequences, or strings, of IM-equipped aircraft. It is important for these strings to maintain stable performance. This paper describes an analytic analysis of the string stability of the latest version of NASA's IM algorithm and a fast-time simulation designed to characterize the string performance of the IM algorithm. The analytic analysis showed that the spacing algorithm has stable poles, indicating that a spacing error perturbation will be reduced as a function of string position. The fast-time simulation investigated IM operations at two airports using constraints associated with the midterm airspace, including limited information of the target aircraft's intended speed profile and limited information of the wind forecast on the target aircraft's route. The results of the fast-time simulation demonstrated that the performance of the spacing algorithm is acceptable for strings of moderate length; however, there is some degradation in IM performance as a function of string position.

    To compare the outcome after laparoscopic incisional and ventral herniorrhaphy (LIVH) for fascial defect larger or equal than 15 cm in width with the outcome after LIVH in patients with hernia defect smaller than 15 cm. From 2003 through 2010, 350 patients were submitted to LIVH. In 70 cases, hernia defect was ≥15 cm in width and in 280 was hernias were often recurrent, double or multiorificial. In the group of larger hernias, the rate of obesity, recurrent hernia and multiorificial hernia was 27.1, 24.2 and 12.8 %, respectively, and in the group of smaller hernias 27.3, 16.1 and 2.8 %, respectively. Patients were interviewed using McGill pain score test to measure postoperative quality of life (QoL) in the mid-term. LIVH for hernia ≥15 cm required longer surgical time (p = 0.034) and postoperative hospital stay (p = 0.0001). Besides, there were higher rate of postoperative prolonged ileus (p = 0.035) and polmonitis (p = 0.001). Overall recurrence rate was 2.6, 8.6 % for larger and 1.1 % for smaller incisional hernias, p = 0.045. Mc Gill pain test revealed no significant difference in the two groups of patients in postoperative QoL within 36 months. Laparoscopic approach seems safe and effective even to repair large incisional hernia, the rate of recurrence was higher, but acceptable, if compared to smaller hernias. To the best of our knowledge, this is the largest reported series of incisional hernias ≥15 cm managed by laparoscopy.

    PURPOSE OF THE STUDY The aim of the study was to evaluate, on the basis of radiographic findings and AOFAS scores, the results of the Grice extra-articular subtalar arthrodesis for treatment of planovalgus foot deformity in cerebral palsy patients. MATERIAL AND METHODS A total of 38 patients (50 feet) with cerebral palsy indicated to the Grice procedure for planovalgus foot deformity between 2006 and 2010 were assessed. The group comprised 18 girls and 20 boys, of whom 10 had spastic quadriparesis (four undergoing bilateral surgery), three had triparesis, four had hemiparesis and 21 had diparesis (treated on both sides in eight). The average age at surgery was 12 years (range, 7 years and 2 months to 17 years and 8 months). All patients were evaluated based on the AOFAS scoring system and radiographic findings before and after surgery. RESULTS The average follow-up was 4.5 years. The average AOFAS score increased from 54.9 points pre-operatively to 76.6 points post-operatively. The pre- and post-operative average values for the talocalcaneal angle were 49.8° and 25°, respectively; for the calcaneal inclination angle they were 8.6° and 13.4°, respectively. DISCUSSION The Grice procedure has long been considered a primary surgical treatment for planovalgus foot deformity in patients with cerebral palsy. Recently, calcaneal osteotomy has been used more frequently, but with no evidence of provably better results. CONSLUSIONS The mid-term results of the Grice extra-articular arthrodesis in our group of cerebral palsy children were very good in terms of both radiographic and AOFAS score evaluation; the latter includes objective assessment as well as the patient's subjective evaluation. Grice procedure, extra-articular subtalar arthrodesis, cerebral palsy, planovalgus foot deformity.

    Background and Objectives Stent coarctoplasty has been approved as the treatment of choice for adult patients with coarctation of the aorta. We have evaluated the early and midterm clinical and procedural results after interventional coarctoplasty. Also, variables that can affect these results were evaluated. Subjects and Methods Gathering clinical, angiographic and procedural data, we evaluated the pre-specified outcomes, including procedural success, complications, the incidence of hypertension after coarctoplasty etc., after the procedure. The effect of pre-specified variables including aortic arch shape, coarctation type and etc. on the procedural result was evaluated. Results Between February 2005 through March 2014, 133 stent coarctoplasty procedures were performed. Median age was 23.5 years old (interquartile range [IQR]:19-28), and 105 (71.9%) were male. Nearly all of the patients were undergone stent coarctoplasty, mostly with cheatham platinum (CP) stents. There was no association between aortic arch morphology and acute procedural complications. Balloon length more than 40 mm (p=0.028), aorta diameter at the site of Coarctation larger than 2.35 mm (p=0.008) was associated with higher rate of restenosis during follow-up. Comparison between the prevalence of hypertension (HTN) before and after coarctoplasty showed a significant reduction in the prevalence of HTN (117 [91.4%] vs. 95 [74.2%] p<0.001). Conclusion Stent coarctoplasty is a low-risk procedure with favorable early and delayed outcomes. Most mortality is related to the patient's comorbid conditions and not to the procedure.

    2008-02-15

    To evaluate mid-term imaging, clinical follow-up, and restenosis rates from patients that had undergone percutaneous transluminal renal artery angioplasty (PTRA) for symptomatic renal artery fibromuscular dysplasia (FMD). Between March 1999 and July 2006, 16 consecutive renal artery FMD patients underwent PTRA for poorly controlled hypertension. The patients were enrolled into this retrospective study after receiving 19 primary and four secondary PTRAs in 19 renal artery segments. Follow-up monitoring of blood pressure, use of antihypertensive medication, and the serum creatinine level after PTRA were assessed at 1, 3, 6, 9, 12 months, and each following year. The degree of restenosis was evaluated with computed tomographic angiography (CTA) after PTRA at 6, 12 months, and every year if possible. Technical and clinical success rates for the treatment of FMD, and restenosis rates for the renal artery were evaluated. The technical success rate for primary PTRA was 79% (15/19) and the complication rate was 16% (3/19). Hypertension improved in 80% (12/15) of the patients after four weeks follow-up, and was finally cured or improved in 93% (14/15) during the mean follow-up period of 23.6 months. There was a cumulative 22% (4/18) restenosis rate during the follow-up period. All of the patients were treated with a second PTRA without complications and all of the patients were cured of hypertension after the second PTRA. Percutaneous transluminal renal artery angioplasty for clinically symptomatic renal FMD is technically and clinically successful and safe to perform. For all patients with restenosis, there was a good response after undergoing a second PTRA.

    Full Text Available Background. Interest in arthroplasty techniques for periarticular or intra-articular fractures in the elderly/osteoporotic patient continues to rise, including for geriatric acetabular fractures. In line with this, many acetabular fracture surgeons are now undertaking acute total hip arthroplasty in elderly/osteoporotic patients. Little is known however of the outcomes of this procedure, beyond the first year after surgery. Questions/Purposes. We determined the clinical outcomes of a series of elderly osteoporotic patients (mean age at surgery 77.4 years treated for acetabular fractures with column fixation and simultaneous total hip arthroplasty, at a mean of 49 months after surgery. Methods. 24 patients (25 hips were reviewed at a mean of 49 months after surgery. The surgical technique employed has previously been described. Radiographs were obtained, and clinical outcomes were assessed using Harris Hip Scores and the Merle d’Aubigné score. Results. 14 hips were available for assessment (9 deceased, 2 lost to follow-up. No patient suffered any complications beyond the perioperative period, no acetabular components were loose clinically or on latest radiographs, and the mean Harris Hip Score was 92. All but one patient scored good or excellent on the Merle d’Aubigné score. Conclusions. Column fixation and simultaneous total hip arthroplasty are a viable option for complex geriatric acetabular fractures, with encouraging midterm results. We conclude that THR is a viable long-term solution in this situation provided that the acetabular columns are stabilised prior to implantation, but more research is needed to aid in overall management decision making.

    Background Evaluation of patient outcomes following transcatheter aortic valve implantation (TAVI) has usually been based on sur-vival and clinical improvement. Studies on quality of life are limited, and data from comprehensive assessments after the procedure are lack-ing. Methods Sixty patients referred for cardiac rehabilitation after TAVI underwent in-hospital and after-discharge multidimensional as-sessments to evaluate clinical, functional, and nutritional statuses, degree of autonomy, cognitive impairment, depression and quality of life. Results On admission to rehabilitation, approximately half of the patients had severe functional impairment and dependence for basic ac-tivities of daily living. During their hospital stay, one-third of the patients suffered significant clinical complications and two had to be trans-ferred to the implantation center. Despite this, the overall outcome was very good. All of the remaining patients were clinically stable at dis-charge and functional status, autonomy and quality of life were improved in most. During a mean follow-up of 540 days (range:192–738 days), five patients died from noncardiac causes, three were hospitalized for cardiac events, and nine for non cardiac reasons. Functional status and autonomy remained satisfactory in the majority of patients and most continued to live independently. Conclusions Patients re-ferred for rehabilitation after TAVI are often very frail, with a high grade of functional impairment, dependence on others and high risk of clinical complications. During a rehabilitation programme, based on a multidimensional assessment and intervention, most patients showed significant improvement in functional status, quality of life, and autonomy, which remained stable in the majority of subjects during mid-term follow-up.

    The aim of this retrospective study was to determine the incidence, clinical presentation and midterm clinical and imaging outcome of endovascular treatment of 34 superior cerebellar artery (SCA) aneurysms in 33 patients. Between January 1995 and January 2007, 2,112 aneurysms were treated in our institution, and 36 aneurysms in 35 patients were located on the SCA (incidence 1.7%). Two of three distal SCA aneurysms were excluded. All the remaining 34 SCA aneurysms, of which 22 (65%) were ruptured and 12 (35%) were unruptured, in 33 patients were treated by endovascular techniques. There were 6 men and 27 women ranging from 29-72 years. In 14 patients (42%) multiple aneurysms were present. Initial angiographic occlusion was (near) complete in 32 aneurysms (94%) and incomplete in 2 aneurysms (6%). Complications leading to permanent morbidity or death occurred in two patients (6.1%, 95% CI 0.6 to 20.60%). Outcome at 6 months follow-up in 31 surviving patients was GOS5 in 26 (84%), GOS4 in 4 (13%) and GOS3 in 1 patient (3%). There were no episodes of (re)bleeding during 118 patient-years of follow-up. The 6-month angiographic follow up in 28 SCA aneurysms and extended angiographic follow-up in 19 showed stable occlusion in 27 aneurysms. No additional treatments were performed. SCA aneurysms are rare with an incidence of 1.7% of treated aneurysms at our institution. They are frequently associated with other aneurysms. Endovascular treatment is effective and safe in excluding the aneurysms from the circulation. (orig.)

    Background/AimsRenal denervation (RDN) emerged as a treatment option for reducing blood pressure (BP) in patients with treatment-resistant hypertension (TRH). However, concerns have been raised regarding the incidence of late renal artery stenosis or thromboembolism after RDN. The goal of the current study was, therefore, to conduct a prospective clinical trial on the mid-term vascular integrity of the renal arteries and the perfusion of the renal parenchyma assessed by magnetic resonance imaging (MRI) in the follow-up after catheter-based RDN.MethodsIn our single-centre investigator initiated study, 51 patients with true TRH underwent catheter-based RDN using the Symplicity Flex{sup TM} catheter (Medtronic Inc., Palo Alto, CA). Follow-up MRI was performed at a median of 11 months (interquartile range 6–18 months) after RDN on a 1.5T MR unit. High-resolution MR angiography (MRA) and MRI results were compared to the baseline digital angiography of renal arteries obtained at time of RDN. In case of uncertainties (N = 2) catheter angiography was repeated.ResultsBoth office and 24-h ambulatory BP were significantly reduced 6 and 12 months after RDN. Renal function remained unchanged 6 and 12 months after RDN. In all patients, MRA excluded new or progression of pre-existing low grade renal artery stenosis as well as focal aneurysms at the sites of radiofrequency ablation. In none of the patients new segmental perfusion deficits in either kidney were detected on MRI.ConclusionsNo vascular or parenchymal complications after radiofrequency-based RDN were detected in 51 patients followed up by MRI.

    Full Text Available Background: Cementless hip prosthesis was designed to provide biologic fixation, without the use of cement. The second generation components have shown more reliable bone ingrowths and survival rates. We are reporting a midterm result of two designs of cementless prosthesis in a unique culture with different social habits and expectations. Methods: 52 primary cementless total hip arthroplasty in 42 patients with the mean age of 48.8 years were retrospectively studied. Two groups of prosthesis had been implanted: Harris-Galante II (HGII in 15 and Versys-Trilogy (V-T in 37 hips, both from Zimmer company. The patients were assessed clinically, radiographically and with Harris hip score, SF36, WOMAC, and MACTAR questionnaires, with 65 months (26-136 mean follow-up. Results: All the V-T prostheses had survived well. Eight of HG II were revised by the last follow-up in 19-102 months. All had undergone acetabular revision and 2 combined with femoral revision. Broken tines of HGII cups were seen in 4 radiographs. The 65 months overall survival was 96.2% for femoral and 84.6% for acetabular components. 90% had good or excellent Harris hip scores. The functional scores were poorer in the HG II group. Pain relief and improved walking were the two main patients’ expectations fulfilled in 97.6% and 92.8%, respectively. Conclusions: The outcome of cementless total hip arthroplasty (THA is satisfactory and comparable with the literature based on the results of function and survival of this small comparative group. The use of HGII acetabular component should be abandoned.

    Initial reports with short-term followup of porous tantalum acetabular components and augments for Paprosky IIIA acetabular defects demonstrate high hip scores, low rates of aseptic loosening, and low rates of complications. However, longer-term followup with a larger cohort is needed to determine the durability of these reconstructions. We therefore determined the functional scores, rates of aseptic loosening, and complications in patients with Paprosky IIIA acetabular defects treated with porous tantalum acetabular components and augments. We retrospectively reviewed 37 acetabular revisions in 36 patients (one patient with bilateral revisions) treated with a porous tantalum acetabular component and augment. All patients had defects classified as Type IIIa using the system of Paprosky et al. Harris hip scores were obtained and radiographic examination was performed before surgery and through most recent followup. The minimum followup was 26 months (mean, 60 months; range, 26-106 months). One patient developed aseptic loosening of the acetabular reconstruction requiring revision; seven other patients required further surgery for periprosthetic femoral fracture (two), acute infection (three), and recurrent dislocation (two). Thirty-five of 37 hips had no or occasional pain at final followup. Mean Harris hip scores improved from 33.0 preoperatively (range, 12.6-58.7) to 81.5 postoperatively (range, 27.0-99.8). Although the complication rate requiring further surgery was considerable, most patients with these reconstructions had pain relief and reasonable function with low rates of loosening at midterm followup. Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

    2001-03-01

    Full Text Available We have examined whether cadaver dissection by first year medical students (MIs affected their performance in two test measures: the NBME Gross Anatomy and Embryology Subject Exam (dissection-relevant questions only, and practical exams given at the end of each major section within the course. The dissections for the entire course were divided into 18 regional dissection units and each student was assigned to dissect one third of the regional units; the other two-thirds of the material was learned from the partner-prosected cadavers. Performance for each student on the exams was then assessed as a function of the regions those students actually dissected. While the results indicated a small performance advantage for MIs answering questions on material they had dissected on the NBME Subject Exam questions relevant to dissection (78-88% of total exam, the results were not statistically significant. However, a similar, small performance advantage on the course practical exams was highly significant.

    2017-06-01

    In the current digital and filmless age of radiology, rates of unread radiology exams remain low, however, may still exist in unique environments. Veterans Affairs (VA) health care systems may experience higher rates of unread exams due to coexistence of Veterans Health Information Systems and Technology Architecture (VistA) imaging and commercial picture archiving and communication systems (PACS). The purpose of this patient safety initiative was to identify any unread exams and causes leading to unread exams. Following approval by departmental quality assurance committee, a comprehensive review was performed of all radiology exams within VistA imaging from July 1, 2009 to June 30, 2014 to identify unread radiology exams. Over the 5-year period, the total unread exam rate was calculated to be 0.17%, with the highest yearly unread exam rate of 0.25%. The leading majority of unread exam type was plain radiographs. Analysis revealed unfinished dictations, unassociated accession numbers, technologist errors, and inefficient radiologist work lists as top contributors to unread exams. Once unread radiology exams were discovered and the causes identified, valuable process changes were implemented within our department to ensure simultaneous tracking of all unread exams in VistA imaging as well as the commercial PACS.

    Universities have varying policies on how and when to perform student evaluations of courses and teachers. More empirical evidence of the consequences of such policies on quality enhancement of teaching and learning is needed. A study (35 courses at the Technical University of Denmark......) was performed to illustrate the effects caused by different handling of mid-term course evaluations on student's satisfaction as measured by end-of-term evaluations. Midterm and end-of-term course evaluations were carried out in all courses. Half of the courses were allowed access to the midterm results....... The evaluations generally showed positive improvements over the semester for courses with access, and negative improvements for those without access. Improvements related to: Student learning, student satisfaction, teaching activities, and communication showed statistically significant average differences of 0...

    We conducted a prospective study of a delta ceramic total hip arthroplasty (THA) to determine the rate of ceramic fracture, to characterise post-operative noise, and to evaluate the mid-term results and survivorship. Between March 2009 and March 2011, 274 patients (310 hips) underwent cementless THA using a delta ceramic femoral head and liner. At each follow-up, clinical and radiological outcomes were recorded. A Kaplan-Meier analysis was undertaken to estimate survival. Four patients (four hips) died and 18 patients (20 hips) were lost to follow-up within five years. The remaining 252 patients (286 hips) were followed for a mean of 66.5 months (60 to 84). There were 144 men (166 hips) and 108 women (120 hips) with a mean age of 49.7 years (16 to 83) at surgery. The mean pre-operative Harris Hip Score of 47.1 points improved to 93.8 points at final follow-up. Six patients reported squeaking in seven hips; however, none were audible. Radiolucent lines involving Gruen zones one and/or seven were seen in 52 hips (18.2%). No hip had detectable wear, focal osteolysis or signs of loosening. One hip was revised because of fracture of the ceramic liner, which occurred due to an undetected malseating of the ceramic liner at the time of surgery. One hip was revised for a periprosthetic fracture of the femur, and one hip was treated for periprosthetic joint infection. The six-year survivorship with re-operation for any reason as the endpoint was 99.0% (95% confidence interval 97.8% to 100%). The rate of delta ceramic fracture was 0.3% (one of 286). While ceramic head fracture was dominant in previous ceramic-on-ceramic THA, fracture of the delta ceramic liner due to malseating is a concern.

  12. Item Analysis an Effective Tool for Assessing Exam Quality, Designing Appropriate Exam and Determining Weakness in Teaching

    Directory of Open Access Journals (Sweden)

    Ghadam Ali Talebi

    2013-10-01

    Full Text Available Introduction: Item analysis is an integrate component of course assessment which helps observe the item characteristics and improve the quality of the course exam. It also provides a guide for improving the teaching method to enhance the students’ learning outcomes. However, item analysis results may not be applied to adjust the way teachers teach and improve the items characteristics. The purpose of this study was to determine the effect of item analysis in improving assessment and teaching quality. Methods: The Item characteristics of the final exam for kinesiology course for physiotherapy students in 2 semesters were studied. Improved and good multiple choice questions (MCQs were then conducted for another semester, followed by application of both good MCQs and improved teaching for the other semester. The item characteristics were compared to observe any effect of good MCQs and teaching on educational performance. Results: The good MCQs along with the improved teaching were associated with the greater mean score and the students who passed the exam rather than those with only good MCQs. The percentage of easy questions (42.5% in students who received good MCQs and improved teaching compared with those (15% who only received good MCQs indicated that the improved pool of questions were shifted from medium to easier questions. Conclusion: We concluded that the item analysis should be followed by revised and improved teaching method. It appears that improved item characteristics are associated with improved teaching method and possibly with an improvement in students’ learning.

    The costs and limitations of clinical encounter documentation using dictation/transcription have provided impetus for increased use of computerized structured data entry to enforce standardization and improve quality. The purpose of the present study is to compare exam report quality of Veterans Affairs (VA) disability exams documented by computerized protocol-guided templates with exams documented in the usual fashion (dictation). Exam report quality for 17,490 VA compensation and pension (C&P) disability exams reviewed in 2005 was compared for exam reports completed by template and exam reports completed in routine fashion (dictation). An additional set of 2,903 exams reviewed for quality the last three months of 2004 were used for baseline comparison. Mean template quality scores of 91 (95% CI 89, 92) showed significant improvement over routine exams conducted during the study period 78 (95% CI 77, 78) and at baseline 73 (95% CI 72, 75). The quality difference among examination types is presented. The results of the present study suggest that use of the standardized, guided documentation templates in VA disability exams produces significant improvement in quality compared with routinely completed exams (dictation). The templates demonstrate the opportunity and capacity for informatics tools to enhance delivery of care when operating in a health system with a sophisticated electronic medical record.

  14. Mid-Term Electricity Market Clearing Price Forecasting with Sparse Data: A Case in Newly-Reformed Yunnan Electricity Market

    Full Text Available For the power systems, for which few data are available for mid-term electricity market clearing price (MCP forecasting at the early stage of market reform, a novel grey prediction model (defined as interval GM(0, N model is proposed in this paper. Over the traditional GM(0, N model, three major improvements of the proposed model are: (i the lower and upper bounds are firstly identified to give an interval estimation of the forecasting value; (ii a novel whitenization method is then established to determine the definite forecasting value from the forecasting interval; and (iii the model parameters are identified by an improved particle swarm optimization (PSO instead of the least square method (LSM for the limitation of LSM. Finally, a newly-reformed electricity market in Yunnan province of China is studied, and input variables are contrapuntally selected. The accuracy of the proposed model is validated by observed data. Compared with the multiple linear regression (MLR model, the traditional GM(0, N model and the artificial neural network (ANN model, the proposed model gives a better performance and its superiority is further ensured by the use of the modified Diebold–Mariano (MDM test, suggesting that it is suitable for mid-term electricity MCP forecasting in a data-sparse electricity market.

    Background: Percutaneous patent foramen ovale (PFO) closure seems to reduce the risk of recurrent thromboembolism. We report the safety and efficacy of percutaneous PFO closure in our centre. Methods: All patients, >16 years of age, who underwent a percutaneous PFO closure in our centre were included. Reoccurrence of stroke, transient ischaemic attack (TIA) and peripheral thromboembolism were assessed. Periprocedural and midterm complications are reported. Results: Eighty-three consecutive patients (mean age 49±13 years) were included. Indications for PFO closure were cryptogenic stroke (59.0%), TIA (33.7%), peripheral embolism (2.4%) and other (4.8%). For PFO closure, a Cardioseal/Starflex device was used in 63 patients and an Amplatzer PFO occluder device in 20 patients. Stroke recurred in 1.2%, TIA in 3.6%, peripheral embolism in 0% during a mean follow-up of 1.9±1.2 years. Major periprocedural complications occurred in 1.2%. The mid-term complication rate was 2.4% and only consisted of minor complications. During follow-up, a residual right-to-left shunt was present in 5.7% of the patients. No significant difference in outcome, complications or residual shunting could be documented between the two device types. Conclusion: In our centre, the percutaneous closure of a PFO seems to be a safe and effective procedure to prevent recurrence of paradoxical thrombo-embolic events. (Neth Heart J 2008;16:332-6.)

    To confirm the validity of using Gore TAG for degenerative descending thoracic aneurysm repair, we evaluated the mid-term clinical outcomes in our single-center experience. From May 2008 to April 2011, elective thoracic endovascular aortic repair (TEVAR) with Gore TAG without left subclavian artery (LSA) coverage for a degenerative descending thoracic aneurysm was performed in 36 consecutive cases. The procedural success rate was 100%, and no patient died within 30 days of the operation. We observed no cases of paraplegia or stroke. The mean follow-up was 33.2 ± 13.0 months (the maximum follow-up was 58.0 months). The actuarial survival rate was 100, 97.2 and 94.4% at 1, 2 and 3 years. There was no aorta-related death at 3 years. Two (5.6%) late distal Type I endoleaks were observed. Freedom form aortic events rate was 97.2, 97.2, and 97.2% at 1, 2, and 3 years respectively. In six cases with bird-beak configurations at the 2-year follow-up, the bird-beak length and angle had increased gradually. Elective TEVAR using the Gore TAG for degenerative descending thoracic aortic aneurysms without LSA coverage is effective and provides satisfactory early and mid-term outcomes. However, since the bird-beak configurations progressed, a conformable and flexible device for the next generation of procedures will be needed.

    We report the primary and mid-term outcome of patients with long chronic iliac artery occlusions after percutaneous excimer-laser-assisted interventional recanalization. Between 2000 and 2001, 43 patients with 46 chronic occlusions of either the common iliac artery (n=27), the external iliac artery (n=13) or both (n=3) underwent laser-assisted percutaneous transluminal angioplasty and implantation of stents. The average length of the occlusion was 57.1{+-}26 mm. After laser-assisted angioplasty and implantation of a total of 60 stents, the patients were followed up for up to 4 years. Patency rates were analyzed by ankle-brachial index (ABI) measurement and duplex ultrasound. The primary technical success rate was 95.3%, with a major complication rate of 6.9%. Clinical improvement as categorized by the Rutherford guidelines could be observed in 97.6% of cases. The ABI of all patients improved from an average of 0.46{+-}0.08 before intervention to 0.97{+-}0.13 at the end of the follow-up period. The overall primary patency rate was 86.1%. Four reinterventions were successful (secondary patency rate 95.4%). The mid-term results of the percutaneous recanalization of iliac artery occlusions with primary and secondary patency rates of 86.1 and 95.4% are similar to those of the treatment of short stenoses.

    2013-05-01

    In light of the structural and content changes to the Medical College Admission Test (MCAT) to be implemented in 2015 and the recent diversity- and social-accountability-based recommendations of the Future of Medical Education in Canada (FMEC) project, the authors review and reexamine the use of the MCAT exam in Canadian medical school admissions decisions.This Perspective article uses a point-counterpoint format to discuss three main advantages and disadvantages of using the MCAT exam in the medical school admissions process, from a Canadian perspective. The authors examine three questions regarding the FMEC recommendations and the revised MCAT exam: (1) Is the MCAT exam equal and useful in Canadian admissions? (2) Does the MCAT exam affect matriculant diversity? and (3) Is the MCAT exam a strong predictor of future performance? They present the most recent arguments and evidence for and against use of the MCAT exam, with the purpose of summarizing these different perspectives for readers.

  2. Ulnar head replacement.

    Science.gov (United States)

    Herbert, Timothy J; van Schoonhoven, Joerg

    2007-03-01

    Recent years have seen an increasing awareness of the anatomical and biomechanical significance of the distal radioulnar joint (DRUJ). With this has come a more critical approach to surgical management of DRUJ disorders and a realization that all forms of "excision arthroplasty" can only restore forearm rotation at the expense of forearm stability. This, in turn, has led to renewed interest in prosthetic replacement of the ulnar head, a procedure that had previously fallen into disrepute because of material failures with early implants, in particular, the Swanson silicone ulnar head replacement. In response to these early failures, a new prosthesis was developed in the early 1990s, using materials designed to withstand the loads across the DRUJ associated with normal functional use of the upper limb. Released onto the market in 1995 (Herbert ulnar head prosthesis), clinical experience during the last 10 years has shown that this prosthesis is able to restore forearm function after ulnar head excision and that the materials (ceramic head and noncemented titanium stem), even with normal use of the limb, are showing no signs of failure in the medium to long term. As experience with the use of an ulnar head prosthesis grows, so does its acceptance as a viable and attractive alternative to more traditional operations, such as the Darrach and Sauve-Kapandji procedures. This article discusses the current indications and contraindications for ulnar head replacement and details the surgical procedure, rehabilitation, and likely outcomes.

    Background Traditional teaching concepts in medical education do not take full advantage of current information technology. We aimed to objectively determine the impact of Tablet PC enhanced training on learning experience and MKSAP® (medical knowledge self-assessment program) exam performance. Methods In this single center, prospective, controlled study final year medical students and medical residents doing an inpatient service rotation were alternatingly assigned to either the active test (Tablet PC with custom multimedia education software package) or traditional education (control) group, respectively. All completed an extensive questionnaire to collect their socio-demographic data, evaluate educational status, computer affinity and skills, problem solving, eLearning knowledge and self-rated medical knowledge. Both groups were MKSAP® tested at the beginning and the end of their rotation. The MKSAP® score at the final exam was the primary endpoint. Results Data of 55 (tablet n = 24, controls n = 31) male 36.4%, median age 28 years, 65.5% students, were evaluable. The mean MKSAP® score improved in the tablet PC (score Δ + 8 SD: 11), but not the control group (score Δ- 7, SD: 11), respectively. After adjustment for baseline score and confounders the Tablet PC group showed on average 11% better MKSAP® test results compared to the control group (pcomputer based integrated training and clinical practice enhances medical education and exam performance. Larger, multicenter trials are required to independently validate our data. Residency and fellowship directors are encouraged to consider adding portable computer devices, multimedia content and introduce blended learning to their respective training programs. PMID:28369063

    2010-07-01

    The standard treatment for end-stage osteoarthritis of the ankle joint in haemophilic patients has been fusion of the ankle joint. Total ankle replacement is still controversial as a treatment option. The objective of this prospective study was to evaluate the mid-term outcome in patients treated with total ankle replacement using an unconstrained three-component ankle implant. Ten haemophilic ankles in eight patients (mean age: 43.2 years, range 26.7-57.5) treated with total ankle replacement were followed up for a minimum of 2.7 years (mean: 5.6, range 2.7-7.6). The outcome was measured with clinical and radiological evaluations. There were no intra- or peri-operative complications. The AOFAS-hindfoot-score increased from 38 (range 8-57) preoperatively to 81 (range 69-95) postoperatively. All patients were satisfied with the results. Four patients became pain free; in the whole patient cohort pain level decreased from 7.1 (range 4-9) preoperatively to 0.8 (range 0-3) postoperatively. All categories of SF-36 score showed significant improvements in quality of life. In one patient, open ankle arthrolysis was performed because of painful arthrofibrosis. For patients with haemophilic osteoarthritis of the ankle joint, total ankle replacement is a valuable alternative treatment to ankle fusion.

    While there are plenty of healthcare-related issues on this year's midterm ballots, Joy Johnson Wilson, left, of the National Conference of State Legislatures, says there were many more that failed to make it. "The cost has gone up to get something on the ballot, and you need an organization to push those measures," she says.

    We used the Medtronic Freestyle valve (Medtronic, Minneapolis, MN) as an orthotopic conduit in pulmonary valve replacement in repaired tetralogy of Fallot and as part of the Ross procedure. Midterm outcomes and hemodynamic status of this conduit were analyzed and performances in both subgroups were compared. From February 2002 to July 2012, 115 Freestyle valves were implanted in 52 patients with tetralogy of Fallot and 63 patients within the Ross procedure. Preoperative and perioperative data were reviewed retrospectively in this bicentric study. Mean age at valve surgery was 37 ± 13 years. Median implanted valve size was 27 mm (21 to 29). Early postoperative mortality was 3.48%. There was 100% follow-up for the survivors at a mean of 4.38 ± 2.52 years. There was 1 case of thromboembolism (0.89%), 6 endocarditis (5.4%), and 9 (7.8%) conduit re-interventions. Echocardiography at discharge and last follow-up showed average peak systolic transvalvular gradients of 12.4 ± 5.1 and 18.7 ± 8.8 mm Hg, respectively. Ten patients had significant proximal anastomotic gradients of greater than 50 mm Hg and 4 moderate conduit regurgitations. Survival was 96.52%. No valve degeneration was seen in 87.82% at 5 years. The only risk factor identified for valve re-intervention was conduit implantation without infundibular hood (p = 0.01 in multivariate analysis). Mid-term data show that Freestyle valves are well suited for pulmonary valve replacement in adults in both categories. The surgical technique used in valve implantation is important to ensure conduit durability. These results and accessibility to the Freestyle valve make this an acceptable alternative to homografts.

    Objectives To assess the impact on stent implantation rate and mid-term outcomes of prolonged high pressure angioplasty of femoropopliteal lesions. Methods We retrospectively enrolled 620 consecutive patients from January 2011 to December 2011 (75.6 ±12.3 years, 355 males, 76.5%in Rutherford class 5-6), referred for critical limb ischemia and submitted to prolonged high-pressure angioplasty of femoropopliteal lesions. The definition of prolonged high-pressure angioplasty includes dilation to at least 18 atm for at least 120 s. Proce-dural data, and clinical and instrumental follow-up were analyzed to assess stent implantation rate and mid-term outcomes. Results The preferred approach was ipsilateral femoral antegrade in 433/620 patients (69.7%) and contralateral cross-over in 164/620 (26.4%) and pop-liteal retrograde+femoral antegrade in 23/620 (3.7%). Techniques included subintimal angioplasty in 427/620 patients (68.8%) and endolu-minal angioplasty in 193/620 patients (31.2%). The prolonged high pressure balloon angioplasty procedure was successful in 86.2%(minor intra-procedural complications rate 15.7%), stent implantation was performed in 74 patients (11.9%), with a significant improvement of ankle-brachial index (0.29 ±0.6 vs. 0.88 ±0.3, P<00.1) and Rutherford class (5.3 ±0.8 vs. 0.7 ±1.9, P<0.01), a primary patency rate of 86.7%, restenosis of 18.6%on Doppler ultrasound and a target lesion revascularization of 14.8%at a mean follow-up of 18.1 ±6.4 months (range 1-24 months). Secondary patency rate was 87.7%. Conclusions Prolonged high pressure angioplasty of femoropopliteal lesions appears to be safe and effective allowing for an acceptable patency and restenosis rates on mid-term.

    Ultrasound is of prO)len accuracy in abdominal and thoracic trauma and may be useful to diagnose extremity injury in situations where radiography is not available such as military and space applications. We prospectively evaluated the utility of extremity , ultrasound performed by trained, non-physician personnel in patients with extremity trauma, to simulate remote aerospace or military applications . Methods: Patients with extremity trauma were identified by history, physical examination, and radiographic studies. Ultrasound examination was performed bilaterally by nonphysician personnel with a portable ultrasound device using a 10-5 MHz linear probe, Images were video-recorded for later analysis against radiography by Fisher's exact test. The average time of examination was 4 minutes. Ultrasound accurately diagnosed extremity, injury in 94% of patients with no false positive exams; accuracy was greater in mid-shaft locations and least in the metacarpa/metatarsals. Soft tissue/tendon injury was readily visualized . Extremity ultrasound can be performed quickly and accurately by nonphysician personnel with excellent accuracy. Blinded verification of the utility of ultrasound in patients with extremity injury should be done to determine if Extremity and Respiratory evaluation should be added to the FAST examination (the FASTER exam) and verify the technique in remote locations such as military and aerospace applications.

    Medical education encompasses globally diverse context and conditions. The Brazilian scenario seemed a natural environment to study the influence of medical education programs and internship duration on the entrance exam for medical residency. This investigation evaluates some methods used during the entrance exam for medical residency as a means to make a distinction between candidates with longer clerkships. Candidates selected for a residency program performed a multiple-choice (MC), an open question (OQ) and OSCE-like tests, an interview and a curriculum analysis for participation in scientific meetings, papers published and voluntary activities. Groups were compared for gender, year of graduation, tests and OSCE scores. Participants were distributed into two groups based on clerkship duration: 2 years or less than 2 years. There was no difference for the MCT score among groups or any of the activities from interview and curriculum analysis. The 2 years clerkship group showed significantly higher OQ (p=0.009) and OSCE-like affective (p=0.025) and knowledge (p=0.002) scores. The OSCE test identified some aspects related to competence acquisition and assessed basic skills and attitudes essential to the supervised practice of medicine during residency. OSCE discriminated aspects not perceived by the sole use of knowledge tests.

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications.

    The quality index among "Medical Parasitology" exam papers and measured data for students in three majors from the university in 2010 were compared and analyzed. The exam papers were formed from the test item bank. The alpha reliability coefficients of the three exam papers were above 0.70. The knowledge structure and capacity structure of the exam papers were basically balanced. But the alpha reliability coefficients of the second major was the lowest, mainly due to quality of test items in the exam paper and the failure of revising the index of test item bank in time. This observation demonstrated that revising the test items and their index in the item bank according to the measured data can improve the quality of test item bank proposition and reduce the difference among exam papers.

    2016-01-01

    Curricular issues of subject Applied Mathematics to Social Sciences are studied in relation to university entrance exams performed in several Spanish regions between 2009–2014. By using quantitative and qualitative analyses, it has been studied how these exams align with curriculum and how they produce a washback on curriculum and teachers’ work. Additionally, one questionnaire about teachers’ practices has been performed, in order to find out how the exams are influencing teaching methodology development. Main results obtained show that evaluation is producing a bias on the official curriculum, substantially simplifying the specific orientation that should guide applied mathematics. Furthermore, teachers’ practices are influenced by the exams, and they usually approach their teaching methodology to the frequent types of exams. Also, slight differences among the teachers lead to distinguish two behavioral subgroups. Results can also be useful in an international context, because of the importance of standardized exit exams in OECD countries. PMID:27936103

    Modular neck femoral stems have a higher-than-anticipated rate of failure in registry results, but large single-center cohort studies are lacking. This is a retrospective cohort of 152 hips implanted with a single titanium stem with a modular titanium neck, presenting clinical, radiographic, and metal ion results at a mean 4.5-year follow-up. Five hips were revised during the study period, for an overall Kaplan-Meier survival of 0.894 at 8 years. There was one modular neck fracture (0.66%), but others demonstrated corrosion or adverse tissue reaction. Serum metal levels demonstrated wide variability. Despite good clinical results in the majority of patients, we confirmed an increased rate of femoral revision at mid-term follow-up, and therefore urge caution in the use of this particular stem design.

    2014-02-01

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine.

  14. Faster Replacement Paths

    2010-01-01

    The replacement paths problem for directed graphs is to find for given nodes s and t and every edge e on the shortest path between them, the shortest path between s and t which avoids e. For unweighted directed graphs on n vertices, the best known algorithm runtime was \\tilde{O}(n^{2.5}) by Roditty and Zwick. For graphs with integer weights in {-M,...,M}, Weimann and Yuster recently showed that one can use fast matrix multiplication and solve the problem in O(Mn^{2.584}) time, a runtime which would be O(Mn^{2.33}) if the exponent \\omega of matrix multiplication is 2. We improve both of these algorithms. Our new algorithm also relies on fast matrix multiplication and runs in O(M n^{\\omega} polylog(n)) time if \\omega>2 and O(n^{2+\\eps}) for any \\eps>0 if \\omega=2. Our result shows that, at least for small integer weights, the replacement paths problem in directed graphs may be easier than the related all pairs shortest paths problem in directed graphs, as the current best runtime for the latter is \\Omega(n^{2.5...

    Purpose: To compare the rate of reintervention and midterm changes in symptom severity (SS) and Total health-related quality of life (HRQoL) scores after uterine artery embolization (UAE) and magnetic resonance-guided high-intensity focused ultrasound (MR-g HIFU) for symptomatic uterine fibroids. Methods: Eighty women (median age 38.3 years), equally eligible for MR-g HIFU and UAE who underwent one of both treatments between 2002 and 2009 at our institution, were included. The primary end point of the study was defined as the rate of reintervention after both therapies. The secondary outcome was defined as changes in SS and Total HRQoL scores after treatment. SS and Total HRQoL scores before treatment and at midterm follow-up (median 13.3 months) were assessed by the uterine fibroid symptom and quality-of-life questionnaire (UFS-QoL) and compared. Results: The rate of reintervention was significantly lower after UAE than after MR-g HIFU (p = 0.002). After both treatments, SS and Total HRQoL scores improved significantly from baseline to follow-up (UAE: p < 0.001, p < 0.001; MR-g HIFU: p = 0.002, p < 0.001). Total HRQoL scores were significantly higher after UAE than after MR-g HIFU (p = 0.032). Changes in the SS scores did not differ significantly for both treatments (p = 0.061). Conclusion: UAE and MR-g HIFU significantly improved the health-related quality of life of women with symptomatic uterine fibroids. After UAE, the change in Total HRQoL score improvement was significantly better, and a significantly lower rate of reintervention was observed.

    This study was designed to evaluate the mid-term results and efficacy of subtalar distraction double bone-block arthrodesis for calcaneal malunion. From January 2004 to June 2007, we operated on 6 patients (10 cases). There were 5 males (9 cases) and 1 female (1 case), four of which presented with bilateral calcaneal malunion. Seven cases were operated on initially. The period between initial injury and arthrodesis was 23 months, and the average follow up period was 58 months. In operation, we applied an extensile lateral approach and arthrodesis was performed through a tricortical double bone-block and cannulated screws. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT were examined to assess union and various parameters. The mean age of the patients was 41 years. All cases achieved radiologic union at the final follow-up. The mean AOFAS Ankle-Hindfoot scale (maximum of 94 points) increased from 43.3 points preoperatively to 85.4 points at the final follow-up. The radiologic analysis of the pre- and postoperative standing lateral radiographs showed improvements of 5.6 mm in talo-calcaneal height, 1.8° in talocalcaneal angle, 5.1° in talar declination angle and 5.3° in talo-first metatarsal angle. Subtalar distraction two bone-block arthrodesis provides overall good results not only in the short term but also the mid-term with significant improvement in clinical and radiologic outcomes. This procedure warrants consideration for managing calcaneal malunion with loss of height and subtalar arthritis.

    Full Text Available Background: With a prevalence of almost 7% of all congenital heart diseases, atrial septal defect (ASD is a common condition. Patent foramen ovale (PFO is also a congenital heart disease which is frequently sustained into adulthood. Objectives: To study the feasibility of closure of ASD and PFU by Starway septal occluder device and the incidence of its inherent complications and procedural failure in 62 patients referred to our center. Methods: Starway septal occluder device was used for closure of ASD and PFO in 62 patients. After left and right heart catheterization, transesophageal echocardiography-guided closure was done for the patients with immediate recording of the results. Patients were followed for 6 months by transesophageal echocardiography for observing short- and mid-term complications. Results: The 62 studied patients were categorized into 2 groups. Group 1 included 31 patients (64% females with ASD (mean±SD age: 26.7±7.6 years. Group 2 consisted of 31 patients (35.6% females with PFO (mean±SD age: 53.5±12.4 years. Size of the right ventricle (RV annulus was significantly (P=0.005 decreased after the intervention in the ASD group. Overall 5 (8% patients developed post-intervention complications (transient ischemic attack, leg edema, and residual shunt and procedural failure—4 (13% in ASD group and 1 (3% in PFO group. None of the patients developed device-related thrombosis, significant arrhythmia, aortic regurgitation and pericardial effusion after intervention. Conclusion: Starway occluder device is effective and safe with very low short- and mid-term complication rates.

    Despite improvements in the results and techniques of catheter-based revascularization, few studies have evaluated the clinical results of the application of new stent designs. We describe the in-hospital and mid-term outcome of patients undergoing a stent NIR implantation. At least 1 Stent NIR was implanted in 1.004 patients (1.136 lesions) recruited from 50 centers in an international, multicenter, prospective, registry (Spain and Portugal NIR stent registry). Inclusion criteria were objective coronary ischemia related to a severe de novo lesion or first restenosis in native vessels with a reference diameter >= 2.75 mm. The primary end-point was the incidence of major adverse cardiac events within the first 7 months of follow-up. The mean age of the patients was 60 years and 82% were male. Angioplasty was indicated due to unstable angina in 61% of the cases. Stent implantation was successfully achieved in 99.6%. Clinical success (angiographic success without in-hospital major events) was achieved in 98.6% of patients. The rate of angiographic restenosis (> 50% stenosis narrowing) was 16% (CI 95%; 11.7-21.2). The accumulated major cardiac adverse event rate at seven months of follow-up was 8.7%: death (0.9%), acute myocardial infarction (1.2%) and target lesion revascularization (6.6%). In the wide setting of the population included in the ESPORT-NIR registry, stent NIR implantation was a highly effective therapy with a good mid-term clinical and angiographic outcome.

    Surveys were mailed to directors of 72 randomly selected practical nursing (PN) schools that administered Elsevier's HESI Exit Exam for Practical Nurses (E2-PN) during the 2006-2007 academic year. Data were collected regarding students' NCLEX-PN outcomes and the schools' benchmarking and remediation policies. The first version of the E2-PN was 99.48% accurate in predicting NCLEX-PN success. Versions two and three of the E2-PN, which were administered to students who were remediated because they did not achieve the faculty-designated benchmark, were also highly accurate in predicting NCLEX-PN success. Most faculties set 850 as their school's E2-PN benchmark, and 73% of the respondents required remediation for students who did not achieve the benchmark score. The most frequently cited remediation strategy was tutoring.

    George Mason University has first semester (PHYS-160) and second semester (PHYS-260) physics course which consist of two sections. One is a traditional lecture style format (TRAD) and the other is a newer format which is a take on the ``flipped'' classroom. This newer style is referred to as Active Learning with Technologies (ALT). This course style has been in place for several years and has been studied before within George Mason University for final grade differences. These studies suggested that the ALT sections performed better, but grade weighting consistency, test time, and test content were not strictly controlled. The purpose of this study is to cross-examine the performance of students in these different class formats during Fall 2016 (PHYS-260) and Spring 2015 (PHYS-160) on very nearly identical exams over identical test times while controlling for almost every variable.

    Porokeratosis is a disorder of epidermal keratinization characterized clinically by a distinctive ridge-like border, and histologically by cornoid lamellae. The known clinical variants of porokeratosis are: classic porokeratosis of Mibelli, disseminated superficial (actinic) porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata, linear porokeratosis and punctate porokeratosis. In 1995, a seventh form was described as porokeratosis ptychotropica: a verrucous form resembling psoriasis involving the gluteal cleft presenting on the histological exam multiple cornoid lamellae. There are very few reports in the literature of this clinical variant. The present study describes the case of a healthy male presenting gluteal hyperkeratotic plaques for 22 years. He had been to several dermatologists, none of them had achieved a definitive diagnosis. We present a typical clinical presentation and its dermoscopy findings, in addition to histological examination that confirmed the diagnosis. PMID:27579746

    2003-05-01

    Full Text Available Abstract Background Many health care professionals use spinal palpatory exams as a primary and well-accepted part of the evaluation of spinal pathology. However, few studies have explored the validity of spinal palpatory exams. To evaluate the status of the current scientific evidence, we conducted a systematic review to assess the content validity of spinal palpatory tests used to identify spinal neuro-musculoskeletal dysfunction. Methods Review of eleven databases and a hand search of peer-reviewed literature, published between 1965–2002, was undertaken. Two blinded reviewers abstracted pertinent data from the retrieved papers, using a specially developed quality-scoring instrument. Five papers met the inclusion/exclusion criteria. Results Three of the five papers included in the review explored the content validity of motion tests. Two of these papers focused on identifying the level of fixation (decreased mobility and one focused on range of motion. All three studies used a mechanical model as a reference standard. Two of the five papers included in the review explored the validity of pain assessment using the visual analogue scale or the subjects' own report as reference standards. Overall the sensitivity of studies looking at range of motion tests and pain varied greatly. Poor sensitivity was reported for range of motion studies regardless of the examiner's experience. A slightly better sensitivity (82% was reported in one study that examined cervical pain. Conclusions The lack of acceptable reference standards may have contributed to the weak sensitivity findings. Given the importance of spinal palpatory tests as part of the spinal evaluation and treatment plan, effort is required by all involved disciplines to create well-designed and implemented studies in this area.

  15. Devising an indicator to detect mid-term abortions in dairy cattle: a first step towards syndromic surveillance of abortive diseases.

    Directory of Open Access Journals (Sweden)

    Anne Bronner

    Full Text Available Bovine abortion surveillance is essential for human and animal health because it plays an important role in the early warning of several diseases. Due to the limited sensitivity of traditional surveillance systems, there is a growing interest for the development of syndromic surveillance. Our objective was to assess whether, routinely collected, artificial insemination (AI data could be used, as part of a syndromic surveillance system, to devise an indicator of mid-term abortions in dairy cattle herds in France. A mid-term abortion incidence rate (MAIR was computed as the ratio of the number of mid-term abortions to the number of female-weeks at risk. A mid-term abortion was defined as a return-to-service (i.e., a new AI taking place 90 to 180 days after the previous AI. Weekly variations in the MAIR in heifers and parous cows were modeled with a time-dependent Poisson model at the département level (French administrative division during the period of 2004 to 2010. The usefulness of monitoring this indicator to detect a disease-related increase in mid-term abortions was evaluated using data from the 2007-2008 episode of bluetongue serotype 8 (BT8 in France. An increase in the MAIR was identified in heifers and parous cows in 47% (n = 24 and 71% (n = 39 of the departements. On average, the weekly MAIR among heifers increased by 3.8% (min-max: 0.02-57.9% when the mean number of BT8 cases that occurred in the previous 8 to 13 weeks increased by one. The weekly MAIR among parous cows increased by 1.4% (0.01-8.5% when the mean number of BT8 cases occurring in the previous 6 to 12 weeks increased by one. These results underline the potential of the MAIR to identify an increase in mid-term abortions and suggest that it is a good candidate for the implementation of a syndromic surveillance system for bovine abortions.

  16. Replacing Alpha-Fetoprotein With Alpha-Fetoprotein-L3 Increases the Sensitivity of Prenatal Screening for Trisomy 21.

    Huai, Lei; Leng, Jianhang; Ma, Shenglin; Huang, Fang; Shen, Junya; Ding, Yu

    This study aimed to investigate the serum concentration of alpha-fetoprotein (AFP)-L3 in midterm pregnancies and its potential application in prenatal trisomy screening. The serum samples from 27 women with trisomy 21 fetuses and 800 women with normal fetuses were examined to measure the concentrations of AFP, AFP-L3, human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin-A. The screening results of various tests consisting of these markers were analyzed. In normal pregnancies within 15-20 weeks of gestation, the medians of serum AFP-L3 were 4.63, 5.70, 5.78, 6.58, 7.03, and 7.25 pg/mL. The median of AFP-L3 MoM in the trisomy 21 group was 0.46, which was significantly lower than the value of 1 in the normal group (P < 0.05). When using a cutoff value of 1/270, the sensitivity of the triple marker test (AFP, hCG, uE3) was improved from 74% to 81% by replacing AFP with AFP-L3, with the false-positive rate slightly increased from 5.4% to 6.8%. Similarly, the sensitivity of the quad marker test (AFP, hCG, uE3, inhibin-A) was improved from 81% to 89% by replacing AFP with AFP-L3, with the false-positive rate slightly increased from 4.6% to 5.6%. Serum AFP-L3 concentration increases along with more weeks of gestation in the midterm pregnancies. Trisomy 21 screening tests with AFP replaced by AFP-L3 have higher sensitivities at the expense of slightly increased false-positive rates. This improvement in screening may help to better prepare the parents and caregivers for the special needs of newborns with trisomy 21.

    To investigate the relationship between the anxiety and blood pressure (BP) and heart rate (HR) increase in peri-exam period. Sixty-four college students(20.0 ± 0.1 year old) were included in this study. The BP and HR were measured in the morning and in the evening for 3 days during the prereview (ba), review, and exam periods. The BP and HR increase amplitudes (HRIA) of review and exam periods were from the difference of corresponding values and basic values, and the BPIA/baBP and HRIA/baHR were calculated. All of the students completed the Self-Rating Anxiety score (SAS) questionnaire the first day of the exam period. Scores over 50 points were used as the standard for anxiety. From the prereview to exam periods, the BP and HR increased gradually. The exam SBPIA (4.3 ± 1.3 vs. 0.3 ± 0.5 mmHg, P family hypertension group had higher anxiety score; meanwhile, their exam BPIAs and HRIAs were significantly higher than their corresponding group. The BP and HR increase in the review and exam period, anxiety is an important factor of BP and HR increase.

    To evaluate the mid-term outcomes of percutaneous radiofrequency ablation (RFA) treatment in patients with small (< 4 cm) renal cell carcinoma (RCC) in Korea. Between 2010 and 2015, 51 patients (40 men and 11 women; median age, 57 years) with biopsyproven 51 RCC were treated using CT-guided RFA. All patients were clinically staged T1aN0M0 prior to RFA. The median tumor size and follow-up period were 2.1 cm (range, 1.0–3.9 cm) and 26 months (4–60 months), respectively. Local tumor progression, distant metastasis, primary and secondary effectiveness rates, and major complication rates were recorded. Estimated glomerular filtration rates (GFRs) between pre-RFA and last follow-up were compared using paired t tests. The 2-year recurrence-free survival rate was calculated using Kaplan-Meier survival analysis. Of the 51 patients, 2 (3.9%) experienced local tumor progression, and 1 (2.0%) had lymph node metastasis after the first RFA session. Primary and secondary effectiveness rates were 96.1% (49/51) and 100% (1/1), respectively. Only 1 patient experienced a major complication (uretero-pelvic stricture) after the second RFA session for treating a local tumor progression, and the major complication rate was 1.9% (1/52). The median pre-RFA and last follow-up GFRs were 87.1 mL/ min/1.73 m{sup 2} (14.2–142.7 mL/min/1.73 m{sup 2}) and 72.0 mL/min/1.73 m{sup 2} (7.2–112.6 mL/min/1.73 m{sup 2}), respectively (p < 0.0001). The 2-year recurrence-free survival rate was 96.0%. CT-guided RFA is a safe and effective treatment in Korean patients with T1a RCC because of excellent mid-term outcomes.

  13. The new AP Physics exams: Integrating qualitative and quantitative reasoning

    Science.gov (United States)

    Elby, Andrew

    2015-04-01

    When physics instructors and education researchers emphasize the importance of integrating qualitative and quantitative reasoning in problem solving, they usually mean using those types of reasoning serially and separately: first students should analyze the physical situation qualitatively/conceptually to figure out the relevant equations, then they should process those equations quantitatively to generate a solution, and finally they should use qualitative reasoning to check that answer for plausibility (Heller, Keith, & Anderson, 1992). The new AP Physics 1 and 2 exams will, of course, reward this approach to problem solving. But one kind of free response question will demand and reward a further integration of qualitative and quantitative reasoning, namely mathematical modeling and sense-making--inventing new equations to capture a physical situation and focusing on proportionalities, inverse proportionalities, and other functional relations to infer what the equation ``says'' about the physical world. In this talk, I discuss examples of these qualitative-quantitative translation questions, highlighting how they differ from both standard quantitative and standard qualitative questions. I then discuss the kinds of modeling activities that can help AP and college students develop these skills and habits of mind.

    The availability of large medical image datasets is critical in many applications such as training and testing of computer aided diagnosis (CAD) systems, evaluation of segmentation algorithms, and conducting perceptual studies. However, collection of large repositories of clinical images is hindered by the high cost and difficulties associated with both the accumulation of data and establishment of the ground truth. To address this problem, we are developing an image blending tool that allows users to modify or supplement existing datasets by seamlessly inserting a real lesion extracted from a source image into a different location on a target image. In this study we focus on the application of this tool to pulmonary nodules in chest CT exams. We minimize the impact of user skill on the perceived quality of the blended image by limiting user involvement to two simple steps: the user first draws a casual boundary around the nodule of interest in the source, and then selects the center of desired insertion area in the target. We demonstrate examples of the performance of the proposed system on samples taken from the Lung Image Database Consortium (LIDC) dataset, and compare the noise power spectrum (NPS) of blended nodules versus that of native nodules in simulated phantoms.

    Ophthalmology is one of the specialties that have particularly benefited from the contribution of ultrasonography exam as a method of investigation. Ultrasonography is very much essential for diagnostic to complement other clinical and laboratory investigations, providing images in real time. The basic principle of diagnostic ultrasound is to study and to interpret the changes they undergo when crossing ultrasonic waves diverse biological properties different sound, and such injuries can be traced in the dynamics or can be documented on photographic paper and thus can diagnose correct certain eye diseases. The indications for performing ultrasound consist in: measurement of distances and volumes, examine difficult or inaccessible case of opaque media; ophthalmoscopic view of a mass lesion, examine the orbit or optic nerve. The advantages of ultrasound for orbital-ocular tumors are represented by the fact that ultrasound is a noninvasive method, safe, well tolerated, less expensive that the advantage of determining the position and distance from structures ocular tumor. High frequency ultrasound provides excellent resolution of 0-1 to 0.01 mm, and serial scans allow tracking progress and measuring lesion diameters tumor while allowing monitoring and evaluation of stereotactic radiation treatments applied to small tumors. In conclusion ultrasound allows not only early diagnosis of eye tumors, but accurate assessment of the proposed therapy and of the evolution of detected mass lesions or tumors.

    Replacement of the asceding aorta is indicated in patients undergoing aortic valve replacement( AVR), if the diameter of the ascending aorta is greater than 5.0 cm. If the diameter of the asceding aorta is from 4.0 to 5.0 cm, it was arguable whether replacement of the ascending aorta should be performed. Nine patients who underwent reoperative ascending aorta replacement after AVR were reviewed retrospectively. Reoperation on the asending aorta replacement was performed 11.8±7.2 years (range 1y5m~23y3m) after AVR. Mean patient age was 69.9±6.3 (range 60~81). In 2 cases, reoperations were performed early year after AVR. Although ascending aorta was dilated at the 1st operation, replacement wasn't performed for the age and minimally invasive cardiac surgery (MICS). In 3 cases, reoperations were performed more than 10 years later. On these cases, ascending aorta aneurysm and dissection occurred with no pain and were pointed out by computed tomography(CT) or ultrasonic cardiogram(UCG). We think that patients with dilatation of the ascending aorta should undergo AVR and aorta replacement at the 1st operation regardness of age. It is important that patients who underwent AVR should undergo a regular checkup on the ascending aorta.

  18. Multiple-choice exams: an obstacle for higher-level thinking in introductory science classes.

    Stanger-Hall, Kathrin F

    2012-01-01

    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities.

    Full Text Available OBJECTIVE: To report the authors' experience with the anomalous origin of the left coronary artery (AOLCA from the pulmonary trunk, emphasizing preoperative data, surgical aspects and midterm results of the follow-up. METHODS: Retrospective analysis of 11 patients operated upon at the Royal Brompton Hospital from October, 84 to April, 97. RESULTS: Nine infants had heart failure (HF and two other children presented with dyspnea and chest pain. All had ECG changes. The echocardiogram identified the anomalous origin of the coronary artery in 7 (64% patients and hemodynamic studies were performed in 7 patients. All infants were operated upon between the 2nd and 10th month of life. Six patients were treated with aortic reimplantation of the left coronary artery, whereas five were operated upon according to the Takeuchi technique. All patients are alive, with clear improvement of the ECG changes and ventricular function, as evaluated by echocardiography. Two patients operated upon according to the Takeuchi technique required additional surgery due to severe supravalvular pulmonary stenosis. CONCLUSION: AOLCA is a rare disease. Most patients show early signs of severe HF associated with ECG findings. Surgical therapy must be instituted early in the disease, preferentially through aortic implantation of the anomalous coronary artery, with a high possibility of success. Shortly after surgery, clinical and ECG improvement, as well as normalization of left ventricular function, should be expected.

    In spite of recent advances in perioperative management, the risk of neurosurgical intervention for patients with chronic renal failure is still considered too high. In this study, coil embolization for incidental aneurysms in such patients is demonstrated in reference to midterm results. A 42-year-old woman with a history of hemodialisis for 7 years presented with subcortical hemorrhage in her right frontal lobe. The magnetic resonance angiography (MRA) demonstrated a distal anterior cerebral artery aneurysm, but it was considered to be unrelated to the hemorrhage. Two and a half months after the hemorrhage the aneurysm was embolized with interlocking detachable coils. Thirty months after embolization, the angiogram revealed the coil compaction and the recanalization of the aneurysm neck. However, 54 months after embolization, the figure of the embolized aneurysm and neck remnant was the same as the previous findings. A 69-year-old woman with a history of hemodialisis for 5 years suddenly experienced left hemiparesis. Computed tomography revealed cerebral infarction in the right frontoparietal white matter. In addition, a left middle cerebral artery aneurysm was unexpectedly found on the MRA. Five months after the onset of the attack, the aneurysm was embolized with a Guglielmi detachable coli. An angiogram obtained 24 months after the embolization showed the aneurysm to be almost completely obliterated. In considering the therapeutic risks and benefits for incidental aneurysms of patients with chronic renal failure, intra-vascular surgery could be recommended as a less invasive treatment.

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure.

  2. Preparedness actions towards seismic risk mitigation for the general public in Martinique, French Lesser Antilles: a mid-term appraisal

    Full Text Available Martinique is a French island in the Lesser Antilles, with a high seismic hazard. In 2006, Martinican stakeholders involved in seismic safety formed the "Réplik" working group ("Aftershock" in French, the first of its kind in this region. This paper addresses a mid-term appraisal of the first seismic awareness campaign organised by Réplik from 2006 to 2011, and how it has modified, or not, local earthquake and tsunami preparedness. Despite efforts from Réplik to assess its efficiency through surveys, a growing gap is noted between the observed awareness and the actual preparedness of the public. As usual, gender, age, educational level, then boredom and saturation contribute to this discrepancy; strong cultural items may also influence the perception of actions. To remain efficient and respond to the public's expectations, Réplik must redirect its actions towards a cultural congruence of information: consideration of religion and local beliefs, comprehensive messages on TV and radio, use of the Creole language, participatory experiences and drills, and a little science. With this, the Réplik stakeholders can hope to increase Martinicans' involvement into the preparedness process, to cope quickly with a strong earthquake and this know-how can be shared with other seismically active islands in the Caribbean.

    Full Text Available Main aim of this paper was to demonstrate the impact of cultivation intensity on economic of selected activities of crop production in Poland. The projection of income of these activities in mid-term perspective, i.e. in 2016, has also been developed. Studies have shown that for cultivation technology of low intensity, as compared to high, the economic results of examined activities were more favourable. The profitability of production, expressed as a ratio of the value of production to economic costs, was higher by 10.0 to 52.7%. According to the projection results, in the highly intensive cultivation, high costs and dynamics of growth, stronger than growth of income, had a negative impact on the level of income. It is expected, even with an exceptionally high yield, income level will be lower than in the cultivation of low intensity. The results show that the use of technological progress can reduce a negative impact of chemicals on the environment while maintaining the high economic efficiency of production.

    Background Whether patients with reduced left ventricular function present worse outcome after transcatheter aortic valve implantation (TAVI) is controversial. The aim of this study was to assess the impact of baseline severe impairment of left ventricular ejection fraction (LVEF) on mortality after TAVI. Methods Six-hundred-forty-nine patients with aortic stenosis underwent TAVI with the CoreValve system (92.8%) or the Edwards SAPIEN valve system (7.2%). Baseline LVEF was measured by the echocardiographic Simpson method. The impact of LVEF ≤ 30% on mortality was assessed by Cox regression. Results Patients with LVEF ≤ 30% (n = 63), as compared to those with LVEF > 30% (n = 586), had a higher prevalence of NHYA class > 2 (P 30%. Thirty-day all-cause mortality was not significantly different between the two groups (11.1% vs. 6.3%, P = 0.14, HR: 1.81, 95% CI: 0.81–4.06). Patients with LVEF ≤ 30% had a trend toward higher risk of 30-day cardiac mortality (11.1% vs. 5.3%; P = 0.06, HR: 2.16, 95% CI: 0.95–4.90), which disappeared after multivariable adjustment (P = 0.22). Conclusions Baseline severe impairment of LVEF is not a predictor of increased short-term and mid-term mortality after TAVI. Selected patients with severe impairment of left ventricular function should not be denied TAVI. PMID:27403137

    Background Now lung volume reduction surgery (LVRS) has become one of the most effective methods for the management of some cases of severe chronic obstructive pulmonary disease (COPD). We evaluated the mid-term effects of LVRS on pulmonary function in patients with severe COPD.Methods Ten male patients with severe COPD aged 38-70 years underwent LVRS and their pulmonary function was assessed before, 3 months and 3 years after surgery. The spirometric and gas exchange parameters included residual volume, total lung capacity, inspiratory capacity, forced vital capacity, forced expiratory volume in one second, diffusion capacity for CO, and arterial blood gas. A 6-minute walk distance (6MWD) test was performed.Results As to preoperative assessment, most spirometric parameters and 6MWD were significantly improved after 3 months and slightly 3 years after LVRS. Gas exchange parameters were significantly improved 3 months after surgery,but returned to the preoperative levels after 3 years.Conclusions LVRS may significantly improve pulmonary function in patients with severe COPD indicating for LVRS.Mid-term pulmonary function 3 years after surgery can be decreased to the level at 3 months after surgery. Three years after LVRS, lung volume and pulmonary ventilation function can be significantly improved, but the improvement in gas exchange function was not significant.

    Full Text Available The aim of the study was to retrospectively review results of operative treatment for coverage deficit of femoral head in children with severe epiphysis displacement in Legg-Calvé-Perthes (LCP disease. The material included 23 shelf acetabuloplasty procedures for LCP disease. The average age at diagnosis was 8.1 years (range 4–12. Mean follow-up was 5.8 years (range from 2.2 to 11.2 years. Mean Reimer's index decreased statistically significantly from a mean of 32% before surgery to 10.0% at the last follow-up (P<0.00001. The mean Wiberg center-edge angle increased also statistically significantly from a mean of 17.3° before procedure to 32.3° at the last follow-up (P<0.00001. According to the Stulberg classification, type I was observed in 2, type II in 13, type III in 6, and type IV in 2 hips. There were no differences in the range of motion or leg length discrepancy in preoperative and postoperative standing. Partial, not significant, bone graft resorption was noted in 6 cases in the first 6–9 months after surgery. To conclude, shelf acetabuloplasty allows achieving good midterm results in the treatment of severe stages of LCP disease. The procedure improves coverage of femoral head and allows its remodelling.

    Introduction Completeness of myocardial revascularization is essential in surgical treatment of coronary artery disease. The aim of this study is to determine the effectiveness of coronary endarterectomy as an adjunct to coronary artery bypass grafting (CABG) in the most difficult cases. Material and methods Among 1559 patients who had CABG in our department, the cases of 17 who underwent an adjunct left anterior descending endarterectomy were analyzed. All procedures were performed with median sternotomy, extracorporeal circulation and in mild hypothermia (34°C), by the same surgeon. No coronary artery endarterectomy was planned before surgery. Results There was no infarction or cardiac arrest during hospitalization. Only one patient required mechanical circulatory support (intra-aortic balloon counterpulsation). Each patient was contacted and investigation for major adverse cardiac and cerebrovascular events (MACCE) was performed. Eleven patients (65%) already underwent midterm clinical evaluation. There was no death, myocardial infarction or cerebrovascular incident during the entire period (mean follow-up at 15.3 months). One patient required urgent coronarography due to chest pain. No other patient had chest pain or significant deterioration of ventricular function in echocardiography. Conclusions Outcomes and potential indications for performing left anterior descending coronary endarterectomy as an adjunct to CABG are discussed. PMID:26855644

    Assigned textbook readings are a common requirement in undergraduate courses, but students often do not complete reading assignments or do not do so until immediately before an exam. This may have detrimental effects on learning and course performance. Regularly scheduled quizzes on reading material may increase completion of reading assignments and therefore course performance. This study examined the effectiveness of compulsory, mastery-based, weekly reading quizzes as a means of improving exam and course performance. Completion of reading quizzes was related to both better exam and course performance. The discussion includes recommendations for the use of quizzes in undergraduate courses. PMID:20046908

  18. A Multi-Neighborhood Multi-Operator Algorithm for the Uncapacitated Exam Proximity Problem

    Directory of Open Access Journals (Sweden)

    Tony Wong

    2015-08-01

    Full Text Available An algorithm featuring multiple local search operators and multiple neighborhood structures is applied to the uncapacitated exam proximity problem. The use of multiplicity is to enable effective interplay between intensification and diversification during the search process. The algorithmic design is inspired by Hansen and Mladenovic's Variable Neighborhood Descent algorithm and the "one operator, one landscape" point of view. Its performance was evaluated using publicly available datasets. For the uncapacitated exam proximity problem, the multi-neighborhood and multi-operator algorithm compared favorably against other search techniques. These results should encourage further research on the application of multiple operator approach as solution techniques to the uncapacitated exam proximity problem.

    PURPOSE OF THE STUDY In view of increasing interest in a relationship between the surface of an implant and its behaviour and longevity in total hip arthroplasty (THA), the aim of this study is to present the clinical and radiographic results, as well as complications, of hip replacement surgery using the cemented femoral stem SAS I. MATERIAL AND METHODS A total of 298 cemented femoral stems SAS I were implanted in 275 patients at our department between 1996 and 2005. The patient average age was 72.1 years, with the range from 64 to 92 years. The pre-operative diagnoses were as follows: primary osteoarthritis in 179 (30.1%); post-dysplastic osteoarthritis in 41 (13.7%); femoral neck fracture in 44 (14.8%); avascular necrosis of the femoral head in 23 (7.7%); rheumatoid arthritis in nine (3%) and other causes in two (0.7%) patients. Of the 275 patients who had the surgery, 186 (204 THAs) underwent clinical and X-ray examination at an average follow-up of 11.5 years (range, 8 to 17 years). The clinical results were used to calculate the Harris hip score and radiographic evaluation was based on antero-posterior views. RESULTS The group of 186 assessed patients (204 THAs) comprised 106 women and 80 men, who were on average 85.4 years old on evaluation (range, 72 to 92 years). Of the remaining patients, 62 patients (64 THAs) died from causes unrelated to the surgery and 27 patients (30 THAs) were lost to follow-up. The functional outcome of surgery assessed by the Harris hip score was excellent in 61 (32.8%), good in 94 (50.5%), satisfactory in 26 (14%) and poor in five (2.7%) patients. The 93.1% SAS I stem longevity was recorded in relation to aseptic loosening; reimplantation for this indication was performed in 14 THAs. No revision surgery for failure due to valgus/varus deviations of the stem was carried out. Of the 204 hips, 188 had femoral stems aligned in neutral, 12 (5.9%) in valgus and four (2%) in varus positions. DISCUSSION The anatomical femoral stem SAS I

    Full Text Available The goals set forth in regulatory documents for the development of Russian education presuppose quantitative evaluation of factors and conditions that ensure students’ achievement of high competence, personality development, and self-realization. Evaluation of intellectual and personality characteristics of first-year university students and study of the relationship among these characteristics thus become important tasks. The research objective was to evaluate relationships among social and abstractlogical types of intelligence, personality characteristics, and exam effectiveness (performance. The study sample was made up of 900 first-year university students (55.2% female and 44.8% male from Tomsk State University who filled in paper-and-pencil forms in Russian: The Evaluation of Choice in Conflict Situations Questionnaire, Raven’s Progressive Matrices, the Self-Organization of Activity, the Reflexivity Type Assessment Test, the Self-Determination Scale, the Satisfaction with Life Scale, and the World Assumptions Scale. Scores on the Unified National Examination in Mathematics (UNE in Mathematics and the first exam results at the university were used to measure academic performance. The data were statistically processed using descriptive analysis, correlation analysis, and factor analysis. The preference for compromising and collaborating strategies indicates a high level of social intelligence and contributes to socio-psychological adaptation of young people to conditions of university education that are new to them, which require greater independence and activity. Social intelligence and abstract-logical intelligence are relatively independent intelligence types. Social intelligence and personality characteristics are not determinants of scores on the UNE in Mathematics. Probably the process of educating students in mathematics in the graduating classes of Russian secondary schools is replaced by training to solve problems on the UNE, so

    All health care practitioners should be facile in the digital rectal exam (DRE) as it provides prostate, rectal and neurological information. The purpose of this study was first to justify our hypothesis that tissue elasticity is indicative of carcinomatous changes. Second, we employed urological surgeons to evaluate our prostate simulator in three ways: (1) authenticate that the elasticity of the simulated prostates accurately represents the range of normal prostate stiffness, (2) determine the range of nodule size reasonably palpable by DRE and (3) discern what degree of elasticity difference within the same prostate suggests malignancy. Institutional Review Board-approved materials characterization, human-subjects experiments, histopathology and chart abstraction of clinical history were performed. Material characterization of 21 ex-vivo prostatectomy specimens was evaluated using a custom-built, portable spherical indentation device while a novel prostate simulator was employed to measure human-subject perception of prostatic state. From the materials characterization, the measurements of the 21 gross prostates and 40 cross-sections yielded 306 data points. Within the same prostate, cancer was always stiffer. Of the seven cases with an abnormal DRE, the DRE accurately identified adenocarcinoma in 85%. From the human-subjects experiments, the simulated prostates evaluated by urologists ranged in stiffness from 8.9 to 91 kPa, mimicking the range found on ex vivo analysis of 4.6-236.7 kPa. The urological surgeons determined the upper limit of stiffness palpated as realistic for a healthy prostate was 59.63 kPa while the lower limit of stiffness was 27.1 kPa. Nodule size less than 7.5 mm was felt to be too small to reasonably palpate. We found it is not the absolute elasticity of the nodule, but rather the relationship of the nodule with the background prostate elasticity that constitutes the critical tactile feedback. Prostate simulator training may lead to

    Galvanic replacement is the spontaneous replacement of surface layers of a metal, M, by a more noble metal, Mnoble, when the former is treated with a solution containing the latter in ionic form, according to the general replacement reaction: nM + mMnoblen+ → nMm+ + mMnoble. The reaction is driven by the difference in the equilibrium potential of the two metal/metal ion redox couples and, to avoid parasitic cathodic processes such as oxygen reduction and (in some cases) hydrogen evolution too...

    A comparison was made of the outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) in high-risk patients. All patients aged > 75 years that underwent a procedure for severe aortic stenosis with or without coronary revascularization at the authors' institution were included in the study; thus, 64 patients underwent TAVI and 188 underwent AVR. Patients in the TAVI group were older (mean age 84 +/- 5 versus 80 +/- 4 years; p < 0.0001) and had a higher logistic EuroSCORE (p = 0.004). Six patients (9%) died during the procedure in the TAVI group, and 23 (12%) died in the AVR group (p = 0.5). Predictors for mortality were: age (p < 0.0001), female gender (p = 0.02), and surgical valve replacement (p = 0.01). Gradients across the implanted valves at one to three months postoperatively were lower in the TAVI group (p < 0.0001). Actuarial survival at one, two and three years was 78%, 64% and 64%, respectively, for TAVI, and 83%, 78% and 75%, respectively, for AVR (p = 0.4). Age was the only predictor for late mortality (p < 0.0001). TAVI patients were older and posed a higher predicted surgical risk. Procedural mortality was lower in the TAVI group, but mid-term survival was similar to that in patients undergoing surgical AVR. Age was the only predictor for late survival. These data support the referral of high-risk patients for TAVI.

    Full Text Available Introduction: Standard straight stems have been recognized as a gold standard implant in the field of hip replacement surgery. However, lately uncemented bone-preserving short stems started to gain more and more popularity. This was reflected in the increasing variety of available models. Up till now, short and mid-term results are available.Patients and methods: In 2002, the cementless short stemmed GHEs was introduced. 380 patients were included in our study between 2002 and 2008. Only GHEs short stems were implanted. The clinical and radiological evaluations were performed in the Orthopaedic Department, Leipzig University Hospitals, on the average of 24 months (3 to 60 months postoperatively.Results: 365 primary implantations and 15 revision implantations were carried out. Average age 60 years. Favourable clinical and radiological outcome was seen in 361/380 patients (95%. Postoperative complications were seen in 19/380 patients (5%: 8 fissures/fractures (2.1%, 5 infections (1.3%, 4 aseptic loosenings (1.1%, 2 dislocations (0.5%.Conclusions: Short stem implants, including our own experience with GHEs model, are satisfying and promising. They represent a valuable supplementation of the treatment modalities in hip replacement surgery. However, long term results are still awaited.

    Full Text Available The current study examined the effect of high school graduation exams on states' graduation rates, states' aggregated SAT scores, and individual students' SAT scores. Three data sources were used: One source identified states requiring a standardized test for graduation; the NCES provided state aggregated data on graduation rates for the class of 2002; and the College Board provided its 2001 SAT database for all test-takers. After controlling for students' demographic characteristics (e.g., race, family education and income, GPA and class rank, regression analyses revealed that states requiring graduation exams had lower graduation rates and lower SAT scores. Individually, students from states requiring a graduation exam performed more poorly on the SAT than did students from states not requiring an exam. The impact of high stakes tests' on students' motivation to stay in school and on the teaching of critical thinking skills (tested by the SAT are discussed.

    Caruthers, Heather Anne

    Analysis of the effect of course structure, including motivational tools, laboratory and how problem solving was presented in lecture on students' exam performance, attitudes toward the subject of chemistry, and problem solving strategy use. Exam performance indicates that the use of ressurection points on the final exam benefits students' learning, especially for the Middle Bottom quartile of students. Laboratory improves students' understanding when the exams correspond to laboratory content. Attitude differences, as measured by the Attitude toward the subject of chemistry inventory version 2, show some differences and the influence of the level of expertise in graduate student teaching assistants. The use of dimensional analysis to solve stoichiometry problems in lecture leads students to use that process to solve novel tasks in a similiar way, even if it is not efficient or effective. The students' familiarity with the content, as well as the problem solving process, influence how they solve tasks.

    In this descriptive prospective study, we evaluate the outcomes of surgery in 98 patients who were scheduled to undergo minimally invasive aortic valve replacement. These patients were compared with a group of 50 patients who underwent scheduled aortic valve replacement through a full sternotomy....... The 30-day mortality rate for the 98 patients was zero, although 14 of the 98 mini-sternotomies had to be converted to complete sternotomies intraoperatively due to technical problems. Such conversion doubled the operative time over that of the planned full sternotomies. In the group of patients whose...... is an excellent operation in selected patients, but its true advantages over conventional aortic valve replacement (other than a smaller scar) await evaluation by means of randomized clinical trial. The "extended mini-aortic valve replacement" operation, on the other hand, is a risky procedure that should...

    Anja J Boevé

    Full Text Available The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

    Matthias Zunhammer

    Full Text Available Academic exam stress is known to compromise sleep quality and alter drug consumption in university students. Here we evaluated if sleeping problems and changes in legal drug consumption during exam stress are interrelated. We used the Pittsburgh Sleep Quality Index (PSQI to survey sleep quality before, during, and after an academic exam period in 150 university students in a longitudinal questionnaire study. Self-reports of alcohol, caffeine, and nicotine consumption were obtained. The Perceived Stress Questionnaire (PSQ-20 was used as a measure of stress. Sleep quality and alcohol consumption significantly decreased, while perceived stress and caffeine consumption significantly increased during the exam period. No significant change in nicotine consumption was observed. In particular, students shortened their time in bed and showed symptoms of insomnia. Mixed model analysis indicated that sex, age, health status, as well as the amounts of alcohol and caffeine consumed had no significant influence on global sleep quality. The amount of nicotine consumed and perceived stress were identified as significant predictors of diminished sleep quality. Nicotine consumption had a small-to-very-small effect on sleep quality; perceived stress had a small-to-moderate effect. In conclusion, diminished sleep quality during exam periods was mainly predicted by perceived stress, while legal drug consumption played a minor role. Exam periods may pose an interesting model for the study of stress-induced sleeping problems and their mechanisms.

    The latest report by the National Crime Records Bureau has positioned Tamil Nadu as the Indian state with highest suicide rate. At least in part, this is happening due to exam pressure among adolescents, emphasizing the imperative need to understand the pattern of anxiety and various factors contributing to it among students. The present study was conducted to analyze the level of state anxiety among board exam attending school students in Tamil Nadu, India. A group of 100 students containing 50 boys and 50 girls from 10th and 12th grades participated in the study and their state anxiety before board exams was measured by Westside Test Anxiety Scale. We found that all board exam going students had increased level of anxiety, which was particularly higher among boys and 12th standard board exam going students. Analysis of various demographic variables showed that students from nuclear families presented higher anxiety levels compared to their desired competitive group. Overall, our results showing the prevalence of state anxiety among board exam going students in Tamil Nadu, India, support the recent attempt taken by Tamil Nadu government to improve student's academic performance in a healthier manner by appointing psychologists in all government schools.

    The ExaMe system for the evaluation of targeted knowledge has been in development since 1998. The new features of the ExaMe system are introduced in this paper. Especially, the new three-layer architecture is described. Besides the system itself, the properties of fixed tests in the ExaMe system are studied. In special detail, the reliability of the fixed tests is discussed. The theory background is explained and some limitations of the reliability are pointed out. Three characteristics used for estimation of reliability of educational tests are discussed: Cronbach's alpha, standardized item alpha and split half coefficient. The relation between these characteristics and reliability and between characteristics themselves is investigated. In more detail, the properties of Cronbach's alpha, the characteristics mostly used for the estimation of reliability, are discussed. A confidence interval is introduced for the characteristics. Since 2000, the serviceability of the ExaMe evaluation system as the supporting evaluation tool has been repeatedly shown at the courses of Ph.D. studies in biomedical informatics at Charles University in Prague. The ExaMe system also opens new possibilities for self-evaluation and distance learning, especially when connected with electronic books on the Internet. The estimation of reliability of tests contains some limitations. Keeping them in mind, we can still get some information about the quality of certain educational tests. Therefore, the estimation of reliability of the fixed tests is implemented in the ExaMe system.

    Purpose: Aim was to determine immediate results and mid-term outcome of the hemoparin-coated (HC) stainless-steel stent (camouflage coating) in the treatment of occlusive lesions of the iliac arteries. Materials and methods: Twenty-eight patients were prospectively treated with the use of a HC stent between January 2007 and March 2010. Clinical examination and color-doppler ultrasound were performed at 1, 3, 6 and 12 months, CT angiography (CTA) or MR angiography (MRA) at 12 months. Indication for treatment was a high-grade stenosis of the common iliac and/or external iliac artery. Results: Successful placement was achieved in all patients. Significant decrease in translesional pressure gradient (>10 mmHg) was measured in 27 patients (96%). In one patient, proximal dissection occurred without flow limitation. A minor complication (small access site hematoma) occurred in one patient (4%). Two patients (7%) were lost to follow-up. After 12 months, stent patency in CTA, MRA and ultrasound was 100%. 20 patients (77%) experienced an initial improvement of at least one clinical stage. In one patient (4%), mild intimal hyperplasia without significant stenosis was observed. In three patients (12%), proximal or distal stenosis occurred. A non-significant increase of mean ankle-brachial index (ABI) after treatment was measured (0.85 ± 0.27 vs. 0.75 ± 0.22, respectively; p = 0.328). Conclusions: The use of HC stents in patients with iliac artery occlusive disease may lead to a lower rate of intimal hyperplasia and thus to increased patency rates even in heavily calcified vessels. However, large-scale prospective trials have to be performed to evaluate the long-term patency rates of the HC coated stents.

    Full Text Available Background: The ventricular septal defect (VSD is the most common form of congenital heart defects. The purpose of this study was to evaluate the results of the early complications and mid-term follow-up of the transcatheter closure of the VSD using the Amplatzer VSD Occluder.Methods: Between April 2012 and October 2013, 110 patients underwent the percutaneous closure of the perimembranous VSD. During the procedure, the size and type of the VSD were obtained via ventriculography. A device at least 2 mm larger than the VSD diameter measured via ventriculography was deployed. The size of the VSD, size of the Amplatzer, and device-size to VSD-size ratio were calculated. After the confirmation of the suitable position of the device via echocardiography and left ventriculography, the device was released. Follow-up evaluations were done at discharge as well as at 1, 6, and 12 months and yearly thereafter for the VSD occlusion and complete heart block.Results: The study population comprised 62 females and 48 males. The mean age and weight of the patients at procedure were 4.3 ± 5.6 years (range: 2 to 14 and 14.9 ± 10.8 kg (range: 10 to 43. The average device size was 7.0 ± 2.5 mm (range: 4 to 14. The VSD occlusion rate was 72.8% at the completion of the procedure and rose up to 99.0% during the follow-up. The most serious significant complication was complete atrioventricular block, which was seen in 2 patients. The mean follow-up duration was 10.9 ± 3.6 months.Conclusion: The transcatheter closure of the perimembranous VSD was a safe and effective treatment with excellent closure rates in our study population. This procedure had neither mortality nor serious complications.

    To evaluate the midterm outcomes and potential risk factors associated with the fascia suture technique (FST) for closure of femoral artery access sites after percutaneous endovascular aneurysm repair (EVAR). Between April 2007 and April 2008, 100 consecutive EVAR cases were evaluated retrospectively. A third of the procedures were emergent (16 ruptured aneurysms). Of the 187 femoral access sites, 160 (85.5%) were closed by the FST as a first choice. Pre- and postoperative chart and imaging data were collected from computerized medical records for analysis of demographics and the rate of complications (bleeding, infection, thrombosis, pseudoaneurysms, and stenosis). Preoperative risk factors for FST failure were analyzed with regard to obesity (based on the subcutaneous fat layer), plaque at the femoral access site, and stenosis based on the pre- and 1-year postoperative computed tomography scans. Of the 160 FST closures, 146 (91.3%) were technically successful. The 14 (8.8%) technical failures were converted to open cutdown intraoperatively because of bleeding (11, 6.8%), inadequate limb perfusion (2, 1.2%), and a broken guidewire (1, 0.6%). Two (1.2%) pseudoaneurysms required surgical repair after 2 weeks. Data from the 1-year follow-up showed no signs of increased stenosis, thrombosis, or formation of plaque. Nine small (<1 cm(3)) pseudoaneurysms were detected and managed conservatively. No preoperative risk factors were associated with FST failure. The fascia suture technique seems to be safe, effective, and simple to use for closing percutaneous access sites after EVAR. Complications are rare, and the outcome is not affected by obesity, femoral calcification, or femoral artery stenosis.

    Full Text Available Objective:Transcatheter closure of secundum atrial septal defect (ASD with Amplatzer device is an alternative procedure to surgical repair, with some limitations. The aim of this study was to assess the initial and mid-term results of the treatment of ASD with Amplatzer septal occluder in children and adolescents. Methods:From May 2003 to January 2008 sixty three consecutive children and adolescent patients underwent transcatheter closure of ASD at a mean±SD age of 8.5±4.8 years (range 2.2 to 18 years. All procedures were performed under local anesthesia and moderate sedation or general anesthesia with transthoracic echocardiography and fluoroscopic guidance. Stretch diameter of ASD was determined by balloon sizing catheter. Device selection was based on and matched to the standard diameter of the septal defect. Follow up at 24 hours, 1 month, 6 months, 12 months and yearly thereafter included physical examination, electrocardiography and transthoracic echocardiography. Findings:The mean ASD diameter, measured with transthoracic echocardiography and balloon catheter were 19.5± 5.5 mm and 20.9± 6.2 mm, respectively. The mean follow up period was 32.4±18.8 months. Deployment of the device was successful in 57 (90.5% and failed in 6 (9.5% patients. The major complication included dislodgement of device in 1 patient and device embolization to right ventricular inlet (surgically removed in 1 patient. The minor complication included transient atrial tachycardia in 10 patients, paroxysmal supraventricular tachycardia in 2 patients during procedure, successfully terminated with medication. At 24 hour, 1 month, 6 month and 1 year follow up, total occlusion rates were 73.6 %, 91%, 94.7%, and 94.7%, respectively. Conclusion:Transcatheter occlusion of ASD with Amplatzer device is an effective and safe procedure with minimal complication rate and short hospital stay, as well as excellent short and intermediate outcome in children and adolescents.

    PurposeThe purpose of the study was to assess the safety and midterm effectiveness of endovascular treatment in Trans-Atlantic Inter-Society Consensus II (TASC-II) D femoropopliteal occlusions in patients with critical limb ischemia (CLI).MethodsPatients with CLI who underwent endovascular treatment for TASC-D de novo femoropopliteal occlusive disease between September 2008 and December 2013 were selected. Data included anatomic features, pre- and postprocedure ankle-brachial index, duplex ultrasound, and periprocedural complications. Sustained clinical improvement, limb salvage rate, freedom from target lesion revascularization (TLR), and freedom from target extremity revascularization (TER) were assessed by Kaplan–Meier estimation and predictors of restenosis/occlusion with Cox analysis.ResultsThirty-two patients underwent treatment of 35 TASC-D occlusions. Mean age was 76 ± 9. Mean lesion length was 23 ± 5 cm. Twenty-eight limbs (80 %) presented tissue loss. Seventeen limbs underwent treatment by stent, 13 by stent-graft, and 5 by angioplasty. Mean follow-up was 29 ± 20 months. Seven patients required major amputation and six patients died during follow-up. Eighteen endovascular and three surgical TLR procedures were performed due to restenosis or occlusion. Estimated freedom from TLR and TER rates at 2 years were 41 and 76 %, whereas estimated primary and secondary patency rates were 41 and 79 %, respectively.ConclusionsEndovascular treatment for TASC II D lesions is safe and offers satisfying outcomes. This patient subset would benefit from a minimally invasive approach. Follow-up is advisable due to a high rate of restenosis. Further follow-up is necessary to know the long-term efficacy of these procedures.

  7. Integrity of disposable nitrile exam gloves exposed to simulated movement.

    Phalen, Robert N; Wong, Weng Kee

    2011-05-01

    Every year, millions of health care, first responder, and industry workers are exposed to chemical and biological hazards. Disposable nitrile gloves are a common choice as both a chemical and physical barrier to these hazards, especially as an alternative to natural latex gloves. However, glove selection is complicated by the availability of several types or formulations of nitrile gloves, such as low-modulus, medical grade, low filler, and cleanroom products. This study evaluated the influence of simulated movement on the physical integrity (i.e., holes) of different nitrile exam glove brands and types. Thirty glove products were evaluated out-of-box and after exposure to simulated whole-glove movement for 2 hr. In lieu of the traditional 1 L water-leak test, a modified water-leak test, standardized to detect a 0.15 ± 0.05 mm hole in different regions of the glove, was developed. A specialized air inflation method simulated bidirectional stretching and whole-glove movement. A worst-case scenario with maximum stretching was evaluated. On average, movement did not have a significant effect on glove integrity (chi-square; p=0.068). The average effect was less than 1% between no movement (1.5%) and movement (2.1%) exposures. However, there was significant variability in glove integrity between different glove types (p≤0.05). Cleanroom gloves, on average, had the highest percentage of leaks, and 50% failed the water-leak test. Low-modulus and medical grade gloves had the lowest percentages of leaks, and no products failed the water-leak test. Variability in polymer formulation was suspected to account for the observed discrepancies, as well as the inability of the traditional 1 L water-leak test to detect holes in finger/thumb regions. Unexpectedly, greater than 80% of the glove defects were observed in the finger and thumb regions. It is recommended that existing water-leak tests be re-evaluated and standardized to account for product variability.

    Graded exams are prerequisites for the admission to the medical state examination. Accordingly the exams must be of good quality in order to allow benchmarking with the faculty and between different universities. Criteria for good quality need to be considered - namely objectivity, validity and reliability. The guidelines for the processing of exams published by the GMA are supposed to help maintaining those criteria. In 2008 the Department of General Medicine at the University of Munich fulfils only 14 of 18 items. A review process, appropriate training of the staff and the introduction of the IMSm software were the main changes that helped to improve the 'GMA-score' to 30 fulfilled items. We see the introduction of the IMSm system as our biggest challenge ahead. IMSm helps to streamline the necessary workflow and improves their quality (e.g. by the detection of cueing, item analysis). Overall, we evaluate the steps to improve the exam process as very positive. We plan to engage co-workers outside the department to assist in the various review processes in the future. Furthermore we think it might be of value to get into contact with other departments and faculties to benefit from each other's question pools.

    This study was conducted to investigate the characteristics of inflow and outflow wastewater of the Bandargaz wastewater treatment plant on the basis of the data collection of operation period and the samples taken during the study. Also the effects of mid-term use of the wastewater for irrigation (from 2005 to 2013) on soil physical and chemical characteristics were studied. For this purpose, 4 samples were taken from the inflow and outflow wastewater and 25 quality parameters were measured. Also, the four soil samples from a depth of 0-30 cm of two rice field irrigated with wastewater in the beginning and middle of the planting season and two samples from one adjacent rice field irrigated with fresh water were collected and their chemical and physical characteristics were determined. Average of electrical conductivity, total dissolved solids, sodium adsorption ratio, chemical oxygen demand and 5 days biochemical oxygen demand in treated wastewater were 1.35 dS/m, 707 ppm, 0.93, 80 ppm and 40 ppm, respectively. Results showed that although some restrictions exist about chlorine and bicarbonate, the treated wastewater is suitable for irrigation based on national and international standards and criteria. In comparison with fresh water, the mid-term use of wastewater caused a little increase of soil salinity. However, it did not lead to increase of soil salinity beyond rice salinity threshold. Also, there were no restrictions on soil in the aspect of salinity and sodium hazard on the basis of many irrigated soil classifications. In comparison with fresh water, the mid-term use of wastewater caused the increase of total N, absorbable P and absorbable K in soil due to high concentration of those elements in treated wastewater.

    Due to the use of radiopharmaceutical positron-emitting in PET exam and realization of tomography by x-ray transmission in CT examination, an increase of dose with hybrid PET/CT technology is expected. However, differences of doses have been reported in many countries for the same type of procedure. It is expected that the dose is an influent parameter to standardize the protocols of PET/CT. This study aimed to estimate the effective doses and absorbed in 65 patients submitted to oncological Protocol in a nuclear medicine clinic in Rio de Janeiro, considering the risk of induction of cancer from the scan. The CT exam-related doses were estimated with a simulator of PMMA and simulated on the lmPACT resistance, which for program effective dose, were considered the weight factors of the lCRP 103. The PET exam doses were estimated by multiplying the activity administered to the patient with the ICRP dose 80 factors. The radiological risk for cancer incidence were estimated according to the ICRP 103. The results showed that the effective dose from CT exam is responsible for 70% of the effective total in a PET/CT scan. values of effective dose for the PET/CT exam reached average values of up to 25 mSv leading to a risk of 2, 57 x 10{sup -4}. Considering that in staging of oncological diseases at least four tests are performed annually, the total risk comes to 1,03x 10{sup -3}.

    The protist Physarum polycephalum is useful for analysis of several aspects of cellular and developmental biology. To expand the opportunities for experimental analysis of this organism, we have developed a method for gene replacement. We transformed Physarum amoebae with plasmid DNA carrying a mutant allele, ardD{Delta}1, of the ardD actin gene; ardD{Delta}1 mutates the critical carboxy-terminal region of the gene product. Because ardD is not expressed in the amoeba, replacement of ardD{sup +} with ardD{Delta}1 should not be lethal for this cell type. Transformants were obtained only when linear plasmid DNA was used. Most transformants carried one copy of ardD{Delta}1 in addition to ardD{sup +}, but in two (5%), ardD{sup +} was replaced by a single copy of ardD{Delta}1. This is the first example of homologous gene replacement in Physarum. ardD{Delta}1 was stably maintained in the genome through growth, development and meiosis. We found no effect of ardD{Delta}l on viability, growth, or development of any of the various cell types of Physarum. Thus, the carboxy-terminal region of the ardD product appears not to perform a unique essential role in growth or development. Nevertheless, this method for homologous gene replacement can be applied to analyze the function of any cloned gene. 38 refs., 6 figs., 1 tab.

    We performed a retrospective cohort study to compare preoperative health-related quality of life (HRQoL) between patients with bilateral and those with unilateral end-stage ankle arthritis. We also compared midterm outcomes in a subgroup of patients who had undergone staged bilateral total ankle replacement (TAR) with the outcomes in the group treated with unilateral TAR. The HRQoL before surgical treatment was compared between 53 patients with bilateral end-stage ankle arthritis identified from the Canadian Orthopaedic Foot and Ankle Society Prospective Ankle Reconstruction Database and 106 patients with unilateral arthritis selected from the same database. Short Form-36 (SF-36) and American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM) scores were used to assess preoperative HRQoL. Midterm outcomes (implant survival, HRQoL, and reoperation and revision rates) were compared between 37 patients who had undergone staged bilateral TAR and 106 patients treated with unilateral TAR; all patients were followed for at least 2 years. Preoperatively, patients with unilateral disease had a higher prevalence of posttraumatic arthritis, whereas patients with bilateral disease had a higher prevalence of primary and secondary arthritis (p arthritis is a more debilitating condition than unilateral arthritis. Patients who underwent staged bilateral TAR benefited as much as patients who underwent unilateral TAR, despite having a worse preoperative health status. Metal component revision rates and implant survival were similar between the 2 groups. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

    Curricular reform is a widespread trend among medical schools. Assessing the impact that pedagogical changes have on students is a vital step in review process. This study examined how a shift from discipline-focused instruction and assessment to integrated instruction and assessment affected student performance in a second-year medical school pathology course. We investigated this by comparing pathology exam scores between students exposed to traditional discipline-specific instruction and exams (DSE) versus integrated instruction and exams (IE). Exam content was controlled, and individual questions were evaluated using a modified version of Bloom's taxonomy. Additionally, we compared United States Medical Licensing Examination (USMLE) step 1 scores between DSE and IE groups. Our findings indicate that DSE students performed better than IE students on complete pathology exams. However, when exam content was controlled, exam scores were equivalent between groups. We also discovered that the integrated exams were composed of a significantly greater proportion of questions classified on the higher levels of Bloom's taxonomy and that IE students performed better on these questions overall. USMLE step 1 exam scores were similar between groups. The finding of a significant difference in content complexity between discipline-specific and integrated exams adds to recent literature indicating that there are a number of potential biases related to curricular comparison studies that must be considered. Future investigation involving larger sample sizes and multiple disciplines should be performed to explore this matter further.

    A modification of the basic design of cobra probes provides for relatively easy replacement of broken thermocouples. Cobra probes are standard tube-type pressure probes that may also contain thermocouples and that are routinely used in wind tunnels and aeronautical hardware. They are so named because in side views, they resemble a cobra poised to attack. Heretofore, there has been no easy way to replace a broken thermocouple in a cobra probe: instead, it has been necessary to break the probe apart and then rebuild it, typically at a cost between $2,000 and $4,000 (2004 prices). The modified design makes it possible to replace the thermocouple, in minimal time and at relatively low cost, by inserting new thermocouple wire in a tube.

    Full Text Available Despite being considered the standard surgical procedure for symptomatic cervical disc disease, anterior cervical decompression and fusion invariably accelerates adjacent segment degeneration. Cervical total disc replacement is a motion-preserving procedure developed as a substitute to fusion. Whether cervical total disc replacement is superior to fusion remains unclear.We comprehensively searched PubMed, EMBASE, Medline, and the Cochrane Library in accordance with the inclusion criteria to identify possible studies. The retrieved results were last updated on December 12, 2014. We classified the studies as short-term and midterm follow-up.Nineteen randomized controlled trials involving 4516 cases were identified. Compared with anterior cervical decompression and fusion, cervical total disc replacement had better functional outcomes (neck disability index [NDI], NDI success, neurological success, neck pain scores reported on a numerical rating scale [NRS], visual analog scales scores and overall success, greater segmental motion at the index level, fewer adverse events and fewer secondary surgical procedures at the index and adjacent levels in short-term follow-up (P 0.05.Cervical total disc replacement presented favorable functional outcomes, fewer adverse events, and fewer secondary surgical procedures. The efficacy and safety of cervical total disc replacement are superior to those of fusion. Longer-term, multicenter studies are required for a better evaluation of the long-term efficacy and safety of the two procedures.

    [Purpose] The purpose of this study was to examine the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam as a clinical tool for quantifying upper extremity function in persons with Parkinson's disease. [Subjects and Methods] Thirty-two persons with idiopathic Parkinson's disease participated in this study. This study measured two clinical outcomes, the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam, to investigate the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam. [Results] The box-and-block test on the more affected side was positive relationship with the box-and-block test on the less affected side. The Unified Parkinson's Disease Rating Scale-motor exam score had a negative correlation with the box-and-block test results for both sides. [Conclusion] A positive association was noted between manual dexterity and motor function in patients with idiopathic Parkinson disease. The results of this study suggest that the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam are good clinical measures that quantify upper extremity function and are necessary for the accurate evaluation of patients and to plan intervention strategies.

    Laboratory courses serve as important gateways to science, technology, engineering, and mathematics education. One of the challenges in assessing laboratory learning is to conduct meaningful and standardized practical exams, especially for large multisection laboratory courses. Laboratory practical exams in life sciences courses are frequently administered by asking students to move from station to station to answer questions, apply knowledge gained during laboratory experiments, interpret data, and identify various tissues and organs using various microscopic and gross specimens. This approach puts a stringent time limit on all questions regardless of the level of difficulty and also invariably increases the potential risk of cheating. To avoid potential cheating in laboratory courses with multiple sections, the setup for practical exams is often changed in some way between sections. In laboratory courses with multiple instructors or teaching assistants, practical exams may be handled inconsistently among different laboratory sections, due to differences in background knowledge, perceptions of the laboratory goals, or prior teaching experience. In this article, we describe a design for a laboratory practical exam that aims to align the assessment questions with well-defined laboratory learning objectives and improve the consistency among all laboratory sections.

    Full Text Available Learners studying for exams sometimes show a lack of awareness in their abilities as tested through the framework of that exam. Instead, such learners focus on the score obtained in exams, and exam preparation includes using textbooks, online materials and timed use of past papers. The purpose of exam-focused flexible self-directed learning modules (FSDLMs at Kanda University of International Studies have been designed to address this by developing learners’ ability to identify their strengths and weaknesses, to make informed decisions about their own learning, and to improve their test-taking skills. Each FSDLM has at its core a diagnostic for learners to use for self-evaluation, often with guidance from a learning advisor. This process leads to the setting of clear goals and the development and implementation of an individual learning plan through a variety of dialogues. Learners have the potential to transfer this skill beyond examination preparation to other areas of learning. In other words, learners’ awareness of needs analysis, planning, implementation and evaluation is fostered with a view to developing their language learning ability within and beyond this module.

  8. Combined assimilation of streamflow and snow water equivalent for mid-term ensemble streamflow forecasts in snow-dominated regions

    2016-10-01

    The potential of data assimilation for hydrologic predictions has been demonstrated in many research studies. Watersheds over which multiple observation types are available can potentially further benefit from data assimilation by having multiple updated states from which hydrologic predictions can be generated. However, the magnitude and time span of the impact of the assimilation of an observation varies according not only to its type, but also to the variables included in the state vector. This study examines the impact of multivariate synthetic data assimilation using the ensemble Kalman filter (EnKF) into the spatially distributed hydrologic model CEQUEAU for the mountainous Nechako River located in British Columbia, Canada. Synthetic data include daily snow cover area (SCA), daily measurements of snow water equivalent (SWE) at three different locations and daily streamflow data at the watershed outlet. Results show a large variability of the continuous rank probability skill score over a wide range of prediction horizons (days to weeks) depending on the state vector configuration and the type of observations assimilated. Overall, the variables most closely linearly linked to the observations are the ones worth considering adding to the state vector due to the limitations imposed by the EnKF. The performance of the assimilation of basin-wide SCA, which does not have a decent proxy among potential state variables, does not surpass the open loop for any of the simulated variables. However, the assimilation of streamflow offers major improvements steadily throughout the year, but mainly over the short-term (up to 5 days) forecast horizons, while the impact of the assimilation of SWE gains more importance during the snowmelt period over the mid-term (up to 50 days) forecast horizon compared with open loop. The combined assimilation of streamflow and SWE performs better than their individual counterparts, offering improvements over all forecast horizons considered

    Objective: To assess the acute and mid-term results of cardiac function improvements and left ventricular outflow tract gradient (LVOTG)changes in 30 patients displaying hypertrophic obstructive cardiomyopathy (HOCM) treated with percutaneous transluminal septal myocardial ablation (PTSMA). Methods: PTSMA was intended for 32 patients comprising of 13 women and 19men (average years being 54.1 ± 15.5) to be treated in accordance with the following inclusion criteria: The New York Heart As-sociation(NYHA) definition for cardiac functional class Ⅲ or Ⅳ , or class Ⅱ but for whom medical therapies were not tolerated or with syncope; intraventricular septal (IVS) and left ventricular posterior wall (LVPW) hypertrophy asymmetrically associated with ratio of IVS to LVPW≥1.3 and LVOTG≥50 mm Hg at rest or ≥100 mm Hg at provocation (Valsalva maneuver). The target vessels were determined by coronary arteriography that demonstrated more than one septal branch and probatory balloon occlusion produced greater than 50% decrease of LVOTG. Once the target vessel established, the alcohol was administrated into septal ventricular via over-the-wire balloon. LVOTG was assessed by means of echocardiography measurements immediately after procedure and 3 months. Simultaneously, cardiac function class was also evaluated. Results: Two patients were abandoned prior to intervention due to inappropriate septal target vessels and DDD Pacemakers were chosed. Immediately after the procedure, resting LVOTG was reduced from 73.8 ± 35.5 to 16.6 ± 7.8 mmHg, at provocation LVOTG from 149.3 ± 42.5 to 61.9 ± 43.0 mmHg(P <0.0001 each) by echocardiography measurements. After 3 months, the mean New York Heart Association class was reduced from 2.8 ± 0.6 to 1.1 ± 1.0(P < 0.0001) and the LVOTG also remained decrease(28.5 ± 6.4 mmHg at rest and 75.3 ± 11.6 mmHg at provocation). Conclusion: PTSMA is a promising nonsurgical technique for relief of symptoms and reduction of LVOTG in

    Abstract Thoracic endovascular aortic repair (TEVAR) in the current era has been chosen as a dominant and minimally invasive treatment for complicated aorta dissection. This study aimed to assess safety and feasibility of TEVAR in acute and chronic type B aortic dissection. Between January 2011 and December 2013, 85 patients with complicated type B aortic dissection undergoing TEVAR were divided into acute aortic dissection (AAD) (n = 60) group and chronic aortic dissection (CAD) group (n = 25). Computed tomography was used to evaluate postoperative changes in maximal aortic diameter and true and false lumen diameters at 3 levels during a mean follow-up period of 26.4 ± 15.6 months. The technical success rate was 100%. In-hospital and 30-day rates of death were 3.3% in acute group and 0 in chronic group. Postdischarge rates of type I leak, type II leak, and retrograde type A dissection were 6.7%, 5.2%, and 3.4% (acute) and 0%, 4.0%, and 4.0% (chronic), respectively. The maximal aorta diameter remained stable in all the 3 levels in both acute and chronic group. The cumulative freedom from all-cause mortality at 3 years was similar in acute and chronic groups (89.5% vs 95.5%, P = .308). The cumulative freedom from aortic-related mortality was also not significantly different in the acute and chronic groups (92.8% vs 95.2%, P = .531). In the thoracic aorta, TEVAR treatment resulted in a significant increase in true lumen (TL) diameter and decrease in false lumen (FL). However, in the abdominal aorta, TEVAR did not lead to significant change in TL and FL diameters. The rates of complete thrombosis thoracic false lumens were better than that in the abdominal false lumen. TEVAR was a safe and effect therapy for complicated acute and chronic type B dissection with low early and mid-term mortality and morbidity. PMID:28700467

    2017-03-01

    Full Text Available Galvanic replacement is the spontaneous replacement of surface layers of a metal, M, by a more noble metal, Mnoble, when the former is treated with a solution containing the latter in ionic form, according to the general replacement reaction: nM + mMnoblen+ → nMm+ + mMnoble. The reaction is driven by the difference in the equilibrium potential of the two metal/metal ion redox couples and, to avoid parasitic cathodic processes such as oxygen reduction and (in some cases hydrogen evolution too, both oxygen levels and the pH must be optimized. The resulting bimetallic material can in principle have a Mnoble-rich shell and M-rich core (denoted as Mnoble(M leading to a possible decrease in noble metal loading and the modification of its properties by the underlying metal M. This paper reviews a number of bimetallic or ternary electrocatalytic materials prepared by galvanic replacement for fuel cell, electrolysis and electrosynthesis reactions. These include oxygen reduction, methanol, formic acid and ethanol oxidation, hydrogen evolution and oxidation, oxygen evolution, borohydride oxidation, and halide reduction. Methods for depositing the precursor metal M on the support material (electrodeposition, electroless deposition, photodeposition as well as the various options for the support are also reviewed.

    Dentin replacement materials are necessary in large cavities to protect the pulp and reduce the bulk of filling material. These materials are layered with a composite resin restorative material. Microleakage caused by poor bonding of composite resin to underlying dentin replacement material will result in pulp damage. The aim of this study was to characterize the interface between dentin replacement materials and composite resin and to measure the shear bond strength after dynamic aging. Biodentine (Septodont, Saint Maur-des-Fosses, France), Theracal LC (Bisco, Schaumburg, IL), and Fuji IX (GC, Tokyo, Japan) were used as dentin replacement materials. They were then overlaid with a total-etch and bonding agent or a self-etch primer and composite resin or a glass ionomer cement. All combinations were thermocycled for 3000 cycles. The interface was characterized using scanning electron microscopy and elemental mapping. Furthermore, the shear bond strength was assessed. The Biodentine surface was modified by etching. The Theracal LC and Fuji IX microstructure was unchanged upon the application of acid etch. The Biodentine and glass ionomer interface showed an evident wide open space, and glass particles from the glass ionomer adhered to the Biodentine surface. Elemental migration was shown with aluminum, barium, fluorine, and ytterbium present in Biodentine from the overlying composite resin. Calcium was more stable. The bond strength between Theracal LC and composite using a total-etch technique followed by self-etch primer achieved the best bond strength values. Biodentine exhibited the weakest bond with complete failure of bonding shown after demolding and thermocycling. Dynamic aging is necessary to have clinically valid data. Bonding composite resin to water-based dentin replacement materials is still challenging, and further alternatives for restoration of teeth using such materials need to be developed.

    Acetabular reconstruction in adults with Hartofilakidis type B developmental dysplasia of the hip is a major technical challenge. The purpose of this retrospective study was to evaluate hip function and radiographic outcomes regarding high hip center at midterm follow-up. From January 1, 2007 to December 31, 2009, 37 patients who had Hartofilakidis type B developmental dysplasia of the hip underwent a primary total hip arthroplasty using a high hip center technique. Functional, radiographic, and survivorship outcomes were evaluated. Of the 37 patients, 31 patients (83.8%) were available for the mean follow-up of 6.1 years (range, 1.5-7.6 years). Thirty-one cementless cups were located at an average vertical distance of 38.1 ± 3.3 mm and at a mean horizontal distance of 35.5 ± 3.4 mm. The mean ratio of the height of the hip center was 2.4% (range, 2.0%-2.9%). The Harris Hip Scores were improved from 50.3 points (range, 38-63 points) preoperatively to 92.3 points (range, 85-100 points) at the final follow-up (P hip center technique in conjunction with a cementless acetabular component seems to be a valuable alternative to achieve satisfactory midterm outcomes for Hartofilakidis type B developmental dysplasia of the hip.

    Advanced endovascular aortic repair can be used to treat patients with extensive and complex aortic disease who are at risk of spinal cord ischaemia. The aim of this study was to compare whether life satisfaction differs between patients with and without spinal cord ischaemia at mid-term follow-up. Nested case-control study. Among patients undergoing advanced endovascular aortic repair between 2009 and 2012, 18 patients with spinal cord ischaemia and 33 without were interviewed at home. The Life Satisfaction Questionnaire (LiSat-11) and the Satisfaction With Life Scale (SWLS) were used. LiSat-11 found that patients with spinal cord ischaemia were more dissatisfied with their activities of daily living than were patients without spinal cord ischaemia (p=0.012). Both groups had similar, very low, scores in the sexual life domain; median 2.0 (interquartile range (IQR) 1.5-3.0) and 3.0 (IQR 2.0-4.0), respectively. There was no difference in SWLS between the groups. This study cohort of patients who underwent advanced endovascular aortic repair was rather homo-genous in their rating of life satisfaction and there was little difference between mid-term survivors who had spinal cord ischaemia and those who did not.

    Full Text Available We introduced voluntary wiki-based exercises to a long-running cognitive psychology course, part of the core curriculum for an undergraduate degree in psychology. Over 2 yearly cohorts, students who used the wiki more also scored higher on the final written exam. Using regression analysis, it is possible to account for students’ tendency to score well on other psychology exams, thus statistically removing some obvious candidate third factors, such as general talent or enthusiasm for psychology, which might drive this correlation. Such an analysis shows that both high- and low-grading students who used the wiki got higher scores on the final exam, with engaged wiki users scoring an average of an extra 5 percentage points. We offer an interpretation of the mechanisms of action in terms of the psychological literature on learning and memory.

    Full Text Available Revision courses should repeat already acquired knowledge and skills and mostly provide a basis for passing the following exam.Aim: The aim of the study is to investigate the influence of a previously attended revision course on the grades achieved in a final exam (Ear, Nose and Throat Diseases. Additionally we ask the question whether the gender of the examiners plays a role concerning the marks or not.Methods: 3961 exams at the Department of Ear, Nose and Throat (ENT Diseases in Vienna were investigated, 725 with revision course (experimental group and 3236 without previous revision course (comparison group. The revision courses were performed in a standardized way concerning form and content, interactive and case based.Both groups were examined uniform in regard to topics and time duration. 16 male and 6 female examiners were involved. The grading followed a five–level scale. The examination marks were calculated in the arithmetic mean and median value for the entire sample, gender dependence was calculated according to the Wilcoxon-Mann-Whitney-Test. The inferential statistics included single- and multiple factorial analyses of variance as well as uni- and multivariate regression models.Results: The experimental group achieved a grade average of 2.54 compared with 2.46 for the comparison group. Splitting up into male and female examiners, an average of 2.54 and 2.58 resp. for the experimental group and 2.44 and 2.61 resp. for the comparison group resulted.

    Isolated tricuspid valve (ITV) operations are infrequent and the decision to operate is controversial. We report a series of ITV operations to outline the current disease status requiring this uncommon procedure with an emphasis on the results of tricuspid valve repair (TVr) versus replacement (TVR). Using our prospective cardiac surgery database, 57 patients who underwent ITV operations between 01/02-03/14 were identified. Median follow up time was 3.5 years [interquartile range (IQR), 0.8-6.7 years]. Fifty-seven patients underwent ITV surgery with a mean age of 54.4±14.9 yrs and 61% were women. Baseline characteristics were similar between patients who underwent TVr (n=18) or TVR (n=39). The etiologies of TV dysfunction were: ITV endocarditis 14/57 (25%), persistent TV regurgitation after left-sided valve surgery in 12/57 (21%), traumatic biopsies and iatrogenic injury from pacing leads in 11/57 (19%), orthotopic heart transplant 9/57 (16%), carcinoid syndrome 3/57 (5%), congenital 2/57 (5%) and idiopathic 5/57 (9%). Overall, 32/57 (56%) patients had prior heart surgery; of which 10/32 (31%) were TV procedures. Bioprosthetic prostheses were used in 34/39 (87%) patients. Of those who had repair, 11/18 (61%) had ring annuloplasty, 3/18 (17%) bicuspidization, and 3/18 (17%) De Vega annuloplasty and one had vegetectomy. Operative mortality was 5.1% (n=2) and 16.7% (n=3) for TVR and TVr groups, respectively (P=0.32), with an overall mortality rate of 8.6%. Postoperative complications included new onset renal failure in 6/39 (15%) of TVr and 2/18 (11%) of TVR (P=0.71) and there were no strokes. Overall survival rates and degree of residual RV dysfunction were similar for the two groups (both P=0.3). Five-year survival was 77% and 84% for TVr and TVR respectively (P=0.52). There was no difference in rates of recurrent tricuspid regurgitation for TVr and TVR (35.7% vs. 23.5%, respectively, P=0.4). ITV surgery is associated with improved but still relatively high

    Medication administration is an important task of registered nurses. According to previous studies, nurses lack theoretical knowledge and drug calculation skills and knowledge-based mistakes do occur in clinical practice. Finnish health care organizations started to develop a systematic verification processes for medication competence at the end of the last decade. No studies have yet been made of nurses' theoretical knowledge and drug calculation skills according to these online exams. The aim of this study was to describe the medication competence of Finnish nurses according to theoretical and drug calculation exams. A descriptive correlation design was adopted. Participants and settings All nurses who participated in the online exam in three Finnish hospitals between 1.1.2009 and 31.05.2014 were selected to the study (n=2479). Quantitative methods like Pearson's chi-squared tests, analysis of variance (ANOVA) with post hoc Tukey tests and Pearson's correlation coefficient were used to test the existence of relationships between dependent and independent variables. The majority of nurses mastered the theoretical knowledge needed in medication administration, but 5% of the nurses struggled with passing the drug calculation exam. Theoretical knowledge and drug calculation skills were better in acute care units than in the other units and younger nurses achieved better results in both exams than their older colleagues. The differences found in this study were statistically significant, but not high. Nevertheless, even the tiniest deficiency in theoretical knowledge and drug calculation skills should be focused on. It is important to identify the nurses who struggle in the exams and to plan targeted educational interventions for supporting them. The next step is to study if verification of medication competence has an effect on patient safety. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Ultrasound (US) is the preferred imaging modality for evaluating suspected pediatric appendicitis. However, borderline appendiceal enlargement or questionable inflammatory changes can confound interpretation and lead to equivocal exams. The purpose of this study was to determine which findings on equivocal US exams are most predictive of appendicitis. All US exams performed for suspected pediatric appendicitis from July 1, 2013, through July 9, 2014, were initially interpreted using a risk-stratified scoring system. Two blinded pediatric radiologists independently reviewed US exams designated as equivocal and recorded the following findings: increased wall thickness, loss of mural stratification, peri-appendiceal fat inflammation, peri-appendiceal fluid, appendicolith and maximum appendiceal diameter. A third pediatric radiologist resolved discrepancies. US features were correlated with the final diagnosis via multivariate analysis. During the study period, 162/3,750 (4.3%) children had US exams initially interpreted as equivocal (mean age 9.8 +/- 3.8 years). Five outpatients were lost to follow-up. Forty-eight of the remaining 157 (30.6%) children had an operative diagnosis of appendicitis. Findings significantly associated with appendicitis were loss of mural stratification (odds ratio [OR] = 6.7, P=0.035), peri-appendiceal fat inflammation (OR = 10.0, Pappendicitis, the difference was not statistically significant. Loss of mural stratification, peri-appendiceal fat inflammation and an appendicolith are significant predictors of appendicitis in children with otherwise equivocal US exams. While maximum appendiceal diameter is not statistically associated with appendicitis in our study, mean appendiceal diameter of 6.7 mm in those without appendicitis suggests that the customary upper normal limit of 6 mm is too sensitive.

    Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students at risk of later psychiatric events. Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves for unadjusted associations and multivariable cause-specific Cox proportional hazard analyses for adjusted hazard ratios (HRs). We identified 12,147 healthy students with exam-related beta-blocker use and 12,147 matched healthy students with no current or prior use of beta-blockers (median age, 19 years; 80.3% women). Among all healthy students, 0.14% had a first-time prescription for a beta-blocker during the exam period with the highest proportion among students aged 19 years (0.39%). Eighty-one percent of the students filled only that single prescription for a beta-blocker during follow-up. During follow-up, 2225 (18.3%) beta-blocker users and 1400 (11.5%) nonbeta-blocker users were prescribed an antidepressant (p risk of antidepressant use (adjusted HRs, 1.68 [95% confidence intervals (CIs), 1.57-1.79], p risk of psychiatric outcomes and might identify psychologically vulnerable students who need special attention.

    One of the challenges of multidetector computerized tomography is to minimize the risk of ionizing radiation using optimized protocols since higher doses are necessary to obtain high image quality. It was also noted that, due to the geometry in image acquisition using MDCT becomes necessary to estimate dose values consistent with the hypothesis clinically and with the specificities of the tomographic equipment. The aim of this study was to estimate the doses in abdomen exams from the data recorded on the MDCT console and dimensions obtained from DICOM images of patients undergoing different clinical protocols. Were collected, from the image DICOM of 101 exams, values of the dose length product (DLP) provided by Philips Health Care - Brilliance 64 equipment console, in order to relate them with the dose values obtained by means of thermoluminescent dosimeters ( TLD ) of CasSo{sub 4}:Mn placed on the surface of a cylindrical simulator abdomen acrylic manufactured under the technical - operational conditions for a typical abdomen exam. From the data obtained, it was possible to find a factor of 1.16 ( 5 % ) indicating that the DLP values Brilliance 64 console underestimate the doses and this should be used with correction factor to estimate the total dose of the patient.

    2015-01-01

    The phenomenon of Iks was first found by anthropologists and biologists, but it is actually a problem of human geography. However, it has not yet drawn extensive attention of geographers. In this paper, a hypothesis of ikization is presented that sudden and violent change of geographical environments results in dismantling of traditional culture, which then result in collective depravity of a nationality. By quantitative analysis and mathematical modeling, the causality between urbanization and ikization is discussed, and the theory of replacement dynamics is employed to interpret the process of ikization. Urbanization is in essence a nonlinear process of population replacement. Urbanization may result in ikization because that the migration of population from rural regions to urban regions always give rise to abrupt changes of geographical environments and traditional culture. It is necessary to protect the geographical environment against disruption, and to inherit and develop traditional culture in order t...

    2016-03-01

    Minimally invasive aortic valve replacement (MIAVR) is defined as aortic valve replacement avoiding full sternotomy. Common approaches include a partial sternotomy right thoracotomy, and a parasternal approach. MIAVR has been shown to have advantages over conventional AVR such as shorter length of stay and smaller amount of blood transfusion and better cosmesis. However, it is also known to have disadvantages such as longer cardiopulmonary bypass and aortic cross-clamp times and potential complications related to peripheral cannulation. Appropriate patient selection is very important. Since the procedure is more complex than conventional AVR, more intensive teamwork in the operating room is essential. Additionally, a team approach during postoperative management is critical to maximize the benefits of MIAVR.

  20. Replacing magnets at the LHC

    CERN Multimedia

    LHC, LSI2, Point 4

    2013-01-01

    CERN engineers have been working through the night this week to move the final replacement dipole magnets into position on the Large Hadron Collider (LHC). Though there are several still to go, the teams expect to have completed the task by the end of this month. Dipole magnets bend the paths of particles as they travel around the circular accelerator. Of the LHC's 1232 dipoles – each 15 metres long and weighing 35 tonnes – 15 are being replaced as part of the long shutdown of CERN's accelerator complex. These 15 magnets suffered wear and tear during the LHC's first 4-year run. Three quadrupole-magnet assemblies – which help to focus particles into a tight beam – have also been replaced. Moving such heavy magnets requires specially adapted cranes and trailers both above and below ground. There are several access points on the LHC. Some, such as the 100-metre vertical access shaft down to the ALICE experiment, are equipped with lifts to allow technical personnel and visitors down to the caverns. Other ...

    Full Text Available Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth. 30 cases (75% had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85% as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05.

    To describe a technique for reconstructing the lost tip support in cases involving caudal septal and premaxillary deficiencies. The study included 120 patients with aesthetic and functional nasal problems resulting from the loss of caudal septal and premaxillary support. An external rhinoplasty approach was performed to reconstruct the lost support using a cartilaginous caudal septum replacement graft and premaxillary augmentation with Mersilene mesh. The majority of cases (75%) involved revisions in patients who had previously undergone 1 or more nasal surgical procedures. A caudal septum replacement graft was combined with premaxillary augmentation in 93 patients (77.5%). The mean follow-up period was 3 years (range, 1-12 years). The technique succeeded in correcting the external nasal deformities in all patients and resulted in a significant improvement in breathing in 74 patients (86%) with preoperative nasal obstruction. There were no cases of infection, displacement, or extrusion. The caudal septum replacement graft proved to be very effective in restoring the lost tip support in patients with caudal septal deficiency. Combining the graft with premaxillary augmentation using Mersilene mesh helped increase support and stability over long-term follow-up.

    Prospective study to evaluate clinical results and complications of endovascular abdominal aortic aneurysm treatment in a mid-term follow-up. Materials and methods: A total of 122 patients (9 females, 113 males, average age 70.0{+-}7,9 years) with abdominal aortic aneurysms were treated with stent grafts (53 Vanguard or Stentor endografts, 69 Talent endografts). Group I consisted of 40 patients who had all aortic tributaries of the aneurysm sac occluded prior to endovalscular grafting, either spontaneously by parietal thrombosis or by selective coil embolization of the respective ostia preserving collateral circulation distal to the vessel occlusion. Group II consisted of 82 patients and included all cases without or with incomplete coil embolization with at least one patent vessel. Stent grafting was performed in general anesthesia in the first 21 patients, followed by peridural anesthesia in 15 cases, and local anesthesia with conscious sedation in 86 cases. The results were evaluated with Spiral-CT, MRI and radiographs of the endovascular graft, with follow-up examinations obtained at 3, 6, 12 months, and every year - Implantation was successfully completed in all cases without primary conversion surgery, laparotomy or any significant complication. Mean follow-up was 29{+-}21 months (maximum 82 months). The 30-day mortality was 0,8% due to a myocardial infarction 3 days after discharge from the hospital. A total of 47 re-interventions were performed in 29 patients (23.8%), with 35 re-interventions in 18 cases with Vanguard or Stentor endografts and 12 re-interventions in 11 patients with Talent endografts. 23 percutaneous re-interventions included distal graft extension (n=11), Wallstent for kinking and limb stenosis (n=3), and secondary coil embolization of collateral vessels (n=9). 24 surgical re-interventions included proximal graft extension (n=6), new endovascular grafts (n=3), surgical clipping of lumbar and mesenteric artery branches for type-II endoleaks

    Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in France. It achieves both adequate excess weight loss and significant reduction in comorbidities. However, fistula is still the most common complication after SG, occurring in more than 3 % of cases, even in specialized centers (Gagner and Buchwald in Surg Obes Relat Dis 10:713-723. doi: 10.1016/j.soard.2014.01.016 , 2014). Its management is not standardized, long, and challenging. We have already reported the short-term results of Roux-en-Y fistulo-jejunostomy (RYFJ) as a salvage procedure in patients with post-SG fistula (Chouillard et al. in Surg Endosc 28:1954-1960 doi: 10.1007/s00464-014-3424-y , 2014). In this study, we analyzed the mid-term results of the RYFJ emphasizing its endoscopic, radiologic, and safety outcome. Between January 2007 and December 2013, we treated 75 patients with post-SG fistula, mainly referred from other centers. Immediate management principles included computerized tomography (CT) scan-guided drainage of collections or surgical peritoneal lavage, nutritional support, and endoscopic stenting. Ultimately, this approach achieved fistula control in nearly two-thirds of the patients. In the remaining third, RYFJ was proposed, eventually leading to fistula control in all cases. The mid-term results (i.e., more than 1 year after surgery) were assessed using anamnesis, clinical evaluation, biology tests, upper digestive tract endoscopy, and IV-enhanced CT scan with contrast upper series. Thirty patients (22 women and 8 men) had RYFJ for post-SG fistula. Mean age was 40 years (range 22-59). Procedures were performed laparoscopically in all but 3 cases (90 %). Three patients (10 %) were lost to follow-up. Mean follow-up period was 22 months (18-90). Mean body mass index (BMI) was 27.4 kg/m(2) (22-41). Endoscopic and radiologic assessment revealed no persistent fistula and no residual collections. Despite the lack of long-term follow-up, RYFJ could be

    Although mid- to long-term results after total ankle replacement have improved because of available second- and third-generation devices, failure of total ankle replacement is still more common compared with total hip replacement and total knee replacement. The portfolio of available total ankle replacement revision component options is small. Furthermore, the bone stock of the tibiotalar region is scarce making it difficult and in some situations impossible to perform revision total ankle replacement. In these cases tibiotalar and tibiotalocalcaneal fusions are valuable options. This article describes which surgical procedures should be performed depending on the initial situation and gives detailed advice on surgical technique, postoperative care, and clinical results.

    In the past few decades, the physics teaching community has witnessed a surge in creative and often effective ways of using technology to improve physics instruction.1-3 Most of these findings suggest how technology can help instructors create interactive learning environments and how interactivity influences the effectiveness of physics learning.4 However, every physics teacher knows that in order for any teaching method to be effective, the exams have to test the skills and concepts addressed by the teacher. Exam content and style sends the clearest message to students about what skills and content are valued by instructors. The mismatch between what we intend to teach and what we effectively test in exams is of great concern to many science teachers. These were our motives for creating data-rich questions to be used in the exams in a large undergraduate first-year physics course at the University of British Columbia. These data-rich questions were developed to support the use of an innovative teaching pedagogy called Interactive Lecture Experiments.3

    Full Text Available Assessment is one of the vital steps in the teaching and learning process. The reported action research examines the effectiveness of an assessment process and inspects the validity of exam questions used for the assessment purpose. The instructors of a college-level mathematics course studied questions used in the final exams during the academic years 2013–2014 and 2014−2015. Using the data from 206 students, the researchers analyzed 54 exam questions with regard to the complexity level, the difficulty coefficient and the discrimination coefficient. Findings indicated that the complexity level correlated with the difficulty coefficient for only one of three semesters. In addition, the correlation between the discrimination coefficient and the difficulty coefficient was found to be statistically significant in all three semesters. The results suggest that all three exams were acceptable; however, further attention should be given to the complexity level of questions used in mathematical tests and that moderate difficulty level questions are better classifying students’ performance.
