Objectives: We evaluated the reliability and predictive ability of an objective structured clinical examination (OSCE) in the assessment of medical students at the completion of a neurology clerkship. Methods: We analyzed data from 195 third-year medical students who took the OSCE. For each student, the OSCE consisted of 2 standardized patient encounters. The scores obtained from each encounter were compared. Faculty clinical evaluations of each student for 2 clinical inpatient rotations were also compared. Hierarchical regression analysis was applied to test the ability of the averaged OSCE scores to predict standardized written examination scores and composite clinical scores. Results: Students' OSCE scores from the 2 standardized patient encounters were significantly correlated with each other (r = 0.347, p < 0.001), and the scores for all students were normally distributed. In contrast, students' faculty clinical evaluation scores from 2 different clinical inpatient rotations were uncorrelated, and scores were skewed toward the highest ratings. After accounting for clerkship order, better OSCE scores were predictive of better National Board of Medical Examiners standardized examination scores (R2Δ = 0.131, p < 0.001) and of better faculty clinical scores (R2Δ = 0.078, p < 0.001). Conclusions: Student assessment by an OSCE provides a reliable and predictive objective assessment of clinical performance in a neurology clerkship. PMID:22855865

The clinical knowledge of medical students on a surgery clerkship is routinely assessed via subjective evaluations from faculty members and residents. Interpretation of these ratings should ideally be valid and reliable. However, prior literature has questioned the correlation between subjective and objective components when assessing students' clinical knowledge. Retrospective cross-sectional data were collected from medical student records at The Johns Hopkins University School of Medicine from July 2009 through June 2011. Surgical faculty members and residents rated students' clinical knowledge on a 5-point, Likert-type scale. Interrater reliability was assessed using intraclass correlation coefficients for students with ≥4 attending surgeon evaluations (n = 216) and ≥4 resident evaluations (n = 207). Convergent validity was assessed by correlating average evaluation ratings with scores on the National Board of Medical Examiners (NBME) clinical subject examination for surgery. Average resident and attending surgeon ratings were also compared by NBME quartile using analysis of variance. There were high degrees of reliability for resident ratings (intraclass correlation coefficient, .81) and attending surgeon ratings (intraclass correlation coefficient, .76). Resident and attending surgeon ratings shared a moderate degree of variance (19%). However, average resident ratings and average attending surgeon ratings shared a small degree of variance with NBME surgery examination scores (ρ(2) ≤ .09). When ratings were compared among NBME quartile groups, the only significant difference was for residents' ratings of students with the lower 25th percentile of scores compared with the top 25th percentile of scores (P = .007). Although high interrater reliability suggests that attending surgeons and residents rate students with consistency, the lack of convergent validity suggests that these ratings may not be reflective of actual clinical knowledge. Both faculty members and residents may benefit from training in knowledge assessment, which will likely increase opportunities to recognize deficiencies and make student evaluation a more valuable tool.

To provide descriptive information about history-taking (HX) and physical examination (PE) performance for U.S. medical students as documented by standardized patients (SPs) during the Step 2 Clinical Skills (CS) component of the United States Medical Licensing Examination. The authors examined two hypotheses: (1) Students perform worse in PE compared with HX, and (2) for PE, students perform worse in the musculoskeletal system and neurology compared with other clinical domains. The sample included 121,767 student-SP encounters based on 29,442 examinees from U.S. medical schools who took Step 2 CS for the first time in 2011. The encounters comprised 107 clinical presentations, each categorized into one of five clinical domains: cardiovascular, gastrointestinal, musculoskeletal, neurological, and respiratory. The authors compared mean percent-correct scores for HX and PE via a one-tailed paired-samples t test and examined mean score differences by clinical domain using analysis of variance techniques. Average PE scores (59.6%) were significantly lower than average HX scores (78.1%). The range of scores for PE (51.4%-72.7%) was larger than for HX (74.4%-81.0%), and the standard deviation for PE scores (28.3) was twice as large as the HX standard deviation (14.7). PE performance was significantly weaker for musculoskeletal and neurological encounters compared with other encounters. U.S. medical students perform worse on PE than HX; PE performance was weakest in musculoskeletal and neurology clinical domains. Findings may reflect imbalances in U.S. medical education, but more research is needed to fully understand the relationships among PE instruction, assessment, and proficiency.

To assess the clinical and radiographic outcomes of patients with recurrent anterior shoulder instability treated with fresh distal tibia allograft (DTA) glenoid reconstruction. Consecutive patients with a minimum 15% anterior glenoid bone loss associated with recurrent anterior instability who underwent stabilization with DTA glenoid reconstruction were retrospectively reviewed. Patients were evaluated with the American Shoulder and Elbow Society score, Western Ontario shoulder instability index, and single numerical assessment evaluation score at a minimum 2 years after surgery. All patients also underwent postoperative imaging evaluation with computed tomography where graft incorporation and allograft angle were measured. Statistical analysis was performed with paired t-tests, with P < .05 considered significant. A total of 27 patients (100% male) with an average age of 31 ± 5 years and an average follow-up of 45 months (range, 30-66) were included. There were significant improvements in preoperative to postoperative American Shoulder and Elbow Society score (63-91, P < .01), Western Ontario shoulder instability index (46% to 11% of normal, P < .01), and single numerical assessment evaluation score (50-90.5, P < .01) outcomes. Analysis of computed tomography data at an average 1.4 years postoperatively (available for 25 patients) showed an allograft healing rate of 89% (range, 80% to 100%), average allograft angle of 14.9° (range, 6.6° to 29.3°), and average allograft lysis of 3% (range, 0% to 25%). Grafts with lesser allograft angles (<15°) were better opposed to the anterior glenoid, showing superior healing and graft incorporation. There were no cases of recurrent instability. At an average follow-up of 45 months, fresh DTA reconstruction for recurrent anterior shoulder instability results in a clinically stable joint with excellent clinical outcomes and minimal graft resorption. Optimal allograft placement resulted in superior bony incorporation with the native glenoid. Level IV, therapeutic case series. Copyright © 2016 Arthroscopy Association of North America.

Background: Students’ perception of the environment within which they study has shown to have a significant impact on their behavior, academic progress and sense of well-being. This study was undertaken to evaluate the students’ perception of their learning environment in an Indian medical school following traditional curricula and to study differences, if any, between the students according to the stages of medical education, i.e., the pre-clinical and clinical stages. Methodology: In the present study, the Dundee Ready Education Environment Measure (DREEM) inventory was administered to undergraduate medical students of first (n = 227), third (n = 175), fifth (n = 171) and seventh (n = 123) semesters. Scores obtained were expressed as mean ± Standard Deviation (SD) and analyzed using one-way ANOVA and Dunnett’s test. P-value < 0.05 was considered as significant. Results: The mean DREEM score for our medical school was 123/200.The first-year students were found to be more satisfied with learning environment (indicated by their higher DREEM score) compared to other semester students. Progressive decline in scores with each successive semester was observed. Evaluating the sub-domains of perception, the registrars in all semesters had a more positive perception of learning (Average mean score: 29.44), their perception of course organizers moved in the right direction (Average mean score: 26.86), their academic self-perception was more on the positive side (Average mean score: 20.14), they had a more positive perception of atmosphere (Average mean score: 29.07) and their social self-perception could be graded as not too bad (Average mean score: 17.02). Conclusion: The present study revealed that all the groups of students perceived their learning environment positively. However, a few problematic areas of learning environment were perceived such as: students were stressed more often; they felt that the course organizers were authoritarian and emphasized factual learning. Implementing more problem-based learning, student counseling and workshops on teaching-learning for educators might enable us to remedy and enrich our learning environment. PMID:24596737

To assess final year medical students' self-perception of their practical skills. The study was conducted at the Faculty of Medicine in Belgrade during compulsory practical sessions in the period December 2-9, 2013 and 390 students agreed to participate (response rate 77.8%). The questionnaire included questions on demographic characteristics, 21 questions on students' self-perception of their practical skills, and 1 question on students' self-perceived readiness to start working with patients. Cronbach's α for the entire scale was 0.891. Students felt most confident about measuring arterial pulse and blood pressure and taking patients' history (average score 10 for all three skills) and least confident about placing a urinary catheter (average score 1) and suturing a wound (average score 2). They rated their readiness to work with patients with 5.0 out of 10.0 points. The total score did not correlate with students' average mark (Spearman's ρ=0.039; P=0.460) and the average mark did not correlate with the self-perceived readiness to work with patients (Spearman's ρ=-0.048; P=0.365). Our study suggests that medical students lack confidence to perform various clinical procedures, particularly those related to surgical interventions. To improve students' confidence, clinical curriculum should include either more hours of practical work or ensure closer supervision of practical training in wards.

Medical schools use a variety of preadmission indices to select potential students. These indices generally include undergraduate grade point average (GPA), Medical College Admission Test (MCAT) scores, and preadmission interviews. To investigate whether the admission indices used by Midwestern University Arizona College of Osteopathic Medicine are associated with the academic and clinical performance of their students. Associations between the prematriculation variables of undergraduate science GPA, undergraduate total GPA, MCAT component scores, and interview scores and the academic and clinical variables of the first- and second-year medical school GPA, Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Cognitive Evaluation (CE) total and discipline scores, scores in clinical rotations for osteopathic competencies, COMLEX-USA Level 2-Performance Evaluation passage, and match status were evaluated. Two-tailed Pearson product-moment correlations with a Bonferroni adjustment were used to examine these relationships. The traditional predictors of science and total undergraduate GPA as well as total and component MCAT scores had small to moderate associations with first- and second-year GPA, as well as COMLEX-USA Level 1 and Level 2-CE total scores. Of all predictors, only the MCAT biological sciences score had a statistically significant correlation with failure of the COMLEX-USA Level 2-Performance Evaluation examination (P=.009). Average interview scores were associated only with the osteopathic competency of medical knowledge (r=0.233; n=209; P=.001), as assessed by clerkship preceptors. No predictors were associated with scores in objective structured clinical encounters or with failing to match to a residency position. The data indicate that traditional predictors of academic performance (undergraduate GPA, undergraduate science GPA, and MCAT scores) have small to moderate association with medical school grades and performance on COMLEX-USA Level 1 and Level 2-CE. This finding requires additional research into the value of the interview in the medical school admissions process and the availability of alternatives that allow better prediction and assessment of applicant performance.

Lung cancer is the most common malignancy and screening can decrease the mortality. High quality screening guideline is necessary and important for effective work. Our study is to review and evaluate the basic characteristics and methodology quality of the current global lung cancer screening guidelines so as to provide useful information for domestic study in the future. Electronic searches were done in English and Chinese databases including PubMed, the Cochrane Library, Web of Science, Embase, CNKI, CBM, Wanfang, and some cancer official websites. Articles were screened according to the predefined inclusion and exclusion criteria by two researchers. The quality of guidelines was assessed by AGREE II. At last, a total of 11 guidelines with methodology were included. The guidelines were issued mainly by USA (81%). Canada and China developed one, respectively. As for quality, the average score in the "Scale and objective" of all guidelines was 80, the average score in the "Participants" was 52, the average score in the "rigorism" was 50, the average score in the "clarity" was 76, the average score in the "application" was 43 and the average score in the "independence" was 59. The highest average score was found in 2013 and 2015. Canada guideline had higher quality in six domains. 7 guidelines were evaluated as A level. The number of clinical guidelines showed an increasing trend. Most guidelines were issued by developed countries with heavy burden. Multi-country contribution to one guideline was another trend. Evidence-based methodology was accepted globally in the guideline development.

Interventional Radiology Clinical Practice Guideline Recommendations for Neurovascular Disorders Are Not Based on High-Quality Systematic Reviews.

In recent years, clinical practice guidelines have been criticized for biased interpretations of research evidence, and interventional radiology is no exception. Our aim was to evaluate the methodologic quality and transparency of reporting in systematic reviews used as evidence in interventional radiology clinical practice guidelines for neurovascular disorders from the Society of Interventional Radiology. Our sources were 9 neurovascular disorder clinical practice guidelines from the Society of Interventional Radiology. We selected 65 systematic reviews and meta-analyses. A Measurement Tool to Assess Systematic Reviews (AMSTAR) and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) tools were used to assess the methodologic quality and reporting transparency of systematic reviews. Radial plots were created on the basis of average scores for PRISMA and AMSTAR items. On the basis of AMSTAR scores, 3 (4.62%) reviews were high-quality, 28 reviews (43.08%) were moderate-quality, and 34 reviews (52.31%) were low-quality, with an average quality score of 3.66 (34.32%; minimum, 0%; maximum, 81.82%). The average PRISMA score was 18.18 (69.41%). We were unable to obtain previous versions for 8 reviews, 7 of which were from the Cochrane Database of Systematic Reviews. The methodologic quality of systematic reviews needs to be improved. Although reporting clarity was much better than the methodologic quality, it still has room for improvement. The methodologic quality and transparency of reporting did not vary much among clinical practice guidelines. This study can also be applied to other medical specialties to examine the quality of studies used as evidence in their own clinical practice guidelines. © 2017 by American Journal of Neuroradiology.

Written Comments Made by Anesthesia Residents When Providing Below Average Scores for the Supervision Provided by the Faculty Anesthesiologist.

2016-06-01

Anesthesia residents in our department evaluate the supervision provided by the faculty anesthesiologist with whom they worked the previous day. What advice managers can best provide to the faculty who receive below-average supervision scores is unknown. The residents provided numerical answers (1 "never," 2 "rarely," 3 "frequently," or 4 "always") to each of the 9 supervision questions, resulting in a total supervision score. A written comment could also be provided. Over 2.5 years, the response rate to requests for evaluation was 99.1%. There were 13,664 evaluations of 76 faculty including 1387 comments. There were 25 evaluations with a comment of disrespectful behavior. For all 25, the question evaluating whether "the faculty treated me respectfully" was answered <4 (i.e., not "always"). The supervision scores were less than for the other evaluations with comments (P < 0.0001). Each increase in the faculty's number of comments of being disrespectful was associated with a lesser mean score (P = 0.0002). A low supervision score (<3.00; i.e., less than "frequent") had an odds ratio of 85 for disrespectful faculty behavior (P < 0.0001). The predictive value of the supervision score not being low for absence of a comment of disrespectful behavior was 99%. That finding was especially useful because 94% of scores below average (<3.80) were not low (≥3.00). There were 6 evaluations with a comment of insufficient faculty presence. Those evaluations had lesser scores than the other evaluations with comments (P < 0.0001). The 6 faculty with 1 such comment had lesser mean scores than the other faculty (P = 0.0071). There were 34 evaluations with a comment about poor-quality teaching. The evaluations related to poor teaching had lesser scores than the other evaluations with comments (P < 0.0001). The faculty who each received such a comment had lesser mean scores than the other faculty (P < 0.0001). Each increase in the faculty's number of comments of poor-quality teaching was associated with a lesser mean score (P = 0.0002). The 9 supervision questions were internally consistent (Cronbach α = 0.948). A faculty with a comment about poor-quality teaching had significant odds of also having a comment about insufficient presence (P = 0.0044). A comment with negative sentiment had significant odds of being about poor-quality teaching rather than being about insufficient presence (odds ratio, 6.00; P < 0.0001). A faculty who has insufficient presence cannot be providing good teaching. Furthermore, there was negligible correlation between supervision scores and faculty clinical assignments. Thus, insufficient faculty presence accounted for a small proportion of below-average supervision scores and low-quality supervision. Furthermore, scores ≥3 have a predictive value for the absence of disrespectful behavior ≅99%. Approximately 94% of the faculty supervision scores that were below average were still ≥3. Consequently, for the vast majority of the faculty-resident-days, quality of teaching distinguished between below- versus above-average supervision scores. This result is consistent with our prior finding of a strong correlation between 6-month supervision scores and assessments of teaching effectiveness. Taken together, when individual faculty anesthesiologists are counseled about their clinical supervision scores, the attribute to emphasize is quality of clinical teaching.

To evaluate return to play after complete thumb ulnar collateral ligament (UCL) injury treated with suture anchor repair for both skill position and non-skill position collegiate football athletes and report minimum 2-year clinical outcomes in this population. For this retrospective study, inclusion criteria were complete rupture of the thumb UCL and suture anchor repair in a collegiate football athlete performed by a single surgeon who used an identical technique for all patients. Data collection included chart review, determination of return to play, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) outcomes. A total of 18 collegiate football athletes were identified, all of whom were evaluated for follow-up by telephone, e-mail, or regular mail at an average 6-year follow-up. Nine were skill position players; the remaining 9 played in nonskill positions. All players returned to at least the same level of play. The average QuickDASH score for the entire cohort was 1 out of 100; QuickDASH work score, 0 out of 100; and sport score, 1 out of 100. Average time to surgery for skill position players was 12 days compared with 43 for non-skill position players. Average return to play for skill position players was 7 weeks postoperatively compared with 4 weeks for non-skill position players. There was no difference in average QuickDASH overall scores or subgroup scores between cohorts. Collegiate football athletes treated for thumb UCL injuries with suture anchor repair had quick return to play, reliable return to the same level of activity, and excellent long-term clinical outcomes. Skill position players had surgery sooner after injury and returned to play later than non-skill position players, with no differences in final level of play or clinical outcomes. Management of thumb UCL injuries in collegiate football athletes can be safely and effectively tailored according to the demands of the player's football position. Therapeutic IV.

Does previous healthcare experience increase success in physician assistant training?

PubMed

Hegmann, Theresa; Iverson, Katie

2016-06-01

Healthcare experience is used by many physician assistant (PA) programs to rank applicants. Despite a large healthcare literature base evaluating admissions factors, little information is available on the relationship of healthcare experience and educational outcomes. We aimed to test whether previous healthcare experience is associated with increased success during the clinical portion of the PA educational process. Hours of direct healthcare experience reported on Central Application Service for Physician Assistants applications for 124 students in the classes of 2009 through 2013 were associated with a calculated average preceptor evaluation score for each student and with average standardized-patient examination scores for a subset of students. Average student age was 28.7 years and median healthcare experience was 2,257 hours (range 390-16,400). Previous healthcare experience was not significantly correlated with preceptor evaluations or standardized-patient examination scores. This 5-year single institution pilot study did not support the hypothesis that healthcare experience is associated with improved clinical year outcomes.

Construct: We investigated the quality of emergency medicine (EM) blogs as educational resources. Online medical education resources such as blogs are increasingly used by EM trainees and clinicians. However, quality evaluations of these resources using gestalt are unreliable. We investigated the reliability of two previously derived quality evaluation instruments for blogs. Sixty English-language EM websites that published clinically oriented blog posts between January 1 and February 24, 2016, were identified. A random number generator selected 10 websites, and the 2 most recent clinically oriented blog posts from each site were evaluated using gestalt, the Academic Life in Emergency Medicine (ALiEM) Approved Instructional Resources (AIR) score, and the Medical Education Translational Resources: Impact and Quality (METRIQ-8) score, by a sample of medical students, EM residents, and EM attendings. Each rater evaluated all 20 blog posts with gestalt and 15 of the 20 blog posts with the ALiEM AIR and METRIQ-8 scores. Pearson's correlations were calculated between the average scores for each metric. Single-measure intraclass correlation coefficients (ICCs) evaluated the reliability of each instrument. Our study included 121 medical students, 88 EM residents, and 100 EM attendings who completed ratings. The average gestalt rating of each blog post correlated strongly with the average scores for ALiEM AIR (r = .94) and METRIQ-8 (r = .91). Single-measure ICCs were fair for gestalt (0.37, IQR 0.25-0.56), ALiEM AIR (0.41, IQR 0.29-0.60) and METRIQ-8 (0.40, IQR 0.28-0.59). The average scores of each blog post correlated strongly with gestalt ratings. However, neither ALiEM AIR nor METRIQ-8 showed higher reliability than gestalt. Improved reliability may be possible through rater training and instrument refinement.

Detection of early symptoms in cervical cancer is crucial for early treatment and survival. To find symptoms of cervical cancer in clinical text, Named Entity Recognition is needed. In this paper the Clinical Entity Finder, a machine-learning tool trained on annotated clinical text from a Swedish internal medicine emergency unit, is evaluated on cervical cancer records. The Clinical Entity Finder identifies entities of the types body part, finding and disorder and is extended with negation detection using the rule-based tool NegEx, to distinguish between negated and non-negated entities. To measure the performance of the tools on this new domain, two physicians annotated a set of clinical notes from the health records of cervical cancer patients. The inter-annotator agreement for finding, disorder and body part obtained an average F-score of 0.677 and the Clinical Entity Finder extended with NegEx had an average F-score of 0.667.

Social difficulties are commonly associated with anxiety disorders in youth, yet are not well specified in the literature. The aim of this study was to identify patterns of social experiences in clinically anxious children and examine the associations with indices of emotional functioning. A model-based cluster analysis was conducted on parent-, teacher-, and child-reports of social experiences with 64 children, ages 7-12 years (M = 8.86 years, SD = 1.59 years; 60.3% boys; 85.7% Caucasian) with a primary diagnosis of separation anxiety disorder, social phobia, and/or generalized anxiety disorder. Follow-up analyses examined cluster differences on indices of emotional functioning. Findings yielded three clusters of social experiences that were unrelated to diagnosis: (1) Unaware Children (elevated scores on parent- and teacher-reports of social difficulties but relatively low scores on child-reports, n = 12), (2) Average Functioning (relatively average scores across all informants, n = 44), and (3) Victimized and Lonely (elevated child-reports of overt and relational victimization and loneliness and relatively low scores on parent- and teacher-reports of social difficulties, n = 8). Youth in the Unaware Children cluster were rated as more emotionally dysregulated by teachers and had a greater number of diagnoses than youth in the Average Functioning group. In contrast, the Victimized and Lonely group self-reported greater frequency of negative affect and reluctance to share emotional experiences than the Average Functioning cluster. Overall, this study demonstrates that social maladjustment in clinically anxious children can manifest in a variety of ways and assessment should include multiple informants and methods.

Daily mood ratings via text message as a proxy for clinic based depression assessment.

Aguilera, Adrian; Schueller, Stephen M; Leykin, Yan

2015-04-01

Mobile and automated technologies are increasingly becoming integrated into mental health care and assessment. The purpose of this study was to determine how automated daily mood ratings are related to the Patient Health Questionnaire-9 (PHQ-9), a standard measure in the screening and tracking of depressive symptoms. There was a significant relationship between daily mood scores and PHQ-9 scores, and between one-week average mood scores and PHQ-9 scores, controlling for linear change in depression scores. PHQ-9 scores were not related to the average of two week mood ratings. This study also constructed models using variance, maximum, and minimum values of mood ratings in the preceding week and two-week periods as predictors of PHQ-9. None of these variables significantly predicted PHQ-9 scores when controlling for daily mood ratings and the corresponding averages for each period. This study only assessed patients who were in treatment for depression, therefore findings might not generalize to the relationship between text message mood ratings for those who are not depressed. The sample was also predominantly Spanish speaking and low-income making generalizability to other populations uncertain. Our results show that automatic text message based mood ratings can be a clinically useful proxy for the PHQ-9. Importantly, this approach avoids the limitations of the PHQ-9 administration, which include length and a higher requirement for literacy. Copyright © 2015 Elsevier B.V. All rights reserved.

Biologic resurfacing arthroplasty with acellular human dermal allograft and platelet-rich plasma (PRP) in young patients with glenohumeral arthritis-average of 60 months of at mid-term follow-up.

The treatment of young patients with glenohumeral arthritis has been challenging. Alternative treatment options include activity modification, arthroscopic débridement, and arthroplasty. Addressing the glenoid during arthroplasty in this population of patients continues to be a significant challenge. In this study, we evaluated the midterm outcomes of hemiarthroplasty with biologic resurfacing of the glenoid with human dermal matrix allograft. Between 2004 and 2011, 55 patients underwent hemiarthroplasty and biologic resurfacing of the glenoid with human dermal matrix allograft. The average age was 50 ± 9 years. Subjective evaluation was performed with the Western Ontario Osteoarthritis of the Shoulder Index, American Shoulder and Elbow Surgeons score, visual analog scale, and Single Assessment Numeric Evaluation. Patients returned to the clinic for clinical examination and radiographic evaluation. The average follow-up was 60 months. The average postoperative American Shoulder and Elbow Surgeons score was 76 ± 22, and the Western Ontario Osteoarthritis of the Shoulder Index score was 76% ± 22%. The visual analog scale score was 2.4 ± 2.6. The average preoperative Single Assessment Numeric Evaluation score was 33% ± 22%, which significantly improved to 72% ± 22% postoperatively. Eighty-one percent of the patients were satisfied (10/47) or highly satisfied (28/47) with their result. With radiographic evaluation, the average joint space was 1 ± 1 mm preoperatively and 2 ± 1 mm postoperatively. A total of 5 cases (9.1%) were revised to anatomic total shoulder arthroplasty with implantation of a glenoid component. Hemiarthroplasty with biologic resurfacing of the glenoid using human dermal matrix allograft can lead to successful midterm outcomes with satisfactory complication and revision rates. Both patient satisfaction and clinical outcome remain high regardless of radiographic outcome. Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

The purpose of this study was to determine whether there are dialectal and gender related differences in nasalance of main Mandarin vowels and three sentences in 400 Chinese normal adults. The mean nasalance score difference for dialect and gender was significant (p < .001) in all speech materials. For different dialects, the average nasalance scores show that Chongqing > Beijing > Shanghai > Guangzhou for the nasal sentence, oro-nasal sentence, /a/, /i/ and /u/. In addition, the average nasalance scores of females were higher than those of males for all speech materials in all dialects. The clinical significance of this study can be helpful in making nasalance clinical decisions for Chinese people with cleft palate, hearing disorders and dysarthria with resonance disorders. It also shows the theoretical and socio-cultural features for linguists considering dialects and gender.

The hypothesis to be tested was that using the SOPROCARE system in fluorescence perio-mode allows scoring of microbial plaque that is comparable to the Turesky modification of the Quigley Hein plaque index (T-QH) and scoring of gingival inflammation comparable to the Silness and Löe gingival inflammation index (GI). Fifty-five subjects with various amounts of microbial plaque were recruited. The T-QH and GI index were recorded. SOPROCARE pictures were recorded in fluorescence perio-mode and in daylight mode. Finally, conventional digital photographs were taken. All pictures were assessed using the same criteria as described for the clinical indices. The average T-QH was 1.1 ± 1.2 (mean ± SD). Scoring with SOPROCARE perio-mode led to a slightly higher average than the T-QH scores. SOPROCARE daylight mode and digital photography showed the highest plaque scores. The average GI index was 0.7 ± 0.9. SOPROCARE in perio-mode scored slightly lower. Linear regression fits between the different clinical indices and SOPROCARE scores were significantly different from zero demonstrating high goodness of fit. The study demonstrated that the SOPROCARE fluorescence assessment tool in perio-mode allows reliable judgment of microbial plaque and gingival inflammation levels similar to the established Turesky-modified Quigley Hein index and the Silness and Löe gingival inflammation index. Training on plaque-free teeth will actually reduce scoring errors. The SOPROCARE fluorescence tool in perio-mode provides reliable evaluation of microbial plaque and gingival inflammation for the dental clinician.

Our department monitors the quality of anesthesiologists' clinical supervision and provides each anesthesiologist with periodic feedback. We hypothesized that greater differentiation among anesthesiologists' supervision scores could be obtained by adjusting for leniency of the rating resident. From July 1, 2013 to December 31, 2015, our department has utilized the de Oliveira Filho unidimensional nine-item supervision scale to assess the quality of clinical supervision provided by faculty as rated by residents. We examined all 13,664 ratings of the 97 anesthesiologists (ratees) by the 65 residents (raters). Testing for internal consistency among answers to questions (large Cronbach's alpha > 0.90) was performed to rule out that one or two questions accounted for leniency. Mixed-effects logistic regression was used to compare ratees while controlling for rater leniency vs using Student t tests without rater leniency. The mean supervision scale score was calculated for each combination of the 65 raters and nine questions. The Cronbach's alpha was very large (0.977). The mean score was calculated for each of the 3,421 observed combinations of resident and anesthesiologist. The logits of the percentage of scores equal to the maximum value of 4.00 were normally distributed (residents, P = 0.24; anesthesiologists, P = 0.50). There were 20/97 anesthesiologists identified as significant outliers (13 with below average supervision scores and seven with better than average) using the mixed-effects logistic regression with rater leniency entered as a fixed effect but not by Student's t test. In contrast, there were three of 97 anesthesiologists identified as outliers (all three above average) using Student's t tests but not by logistic regression with leniency. The 20 vs 3 was significant (P < 0.001). Use of logistic regression with leniency results in greater detection of anesthesiologists with significantly better (or worse) clinical supervision scores than use of Student's t tests (i.e., without adjustment for rater leniency).

It is widely acknowledged that clinical problem-solving is a key skill for dental practitioners. The aim of this study was to determine if students in a hybrid problem-based learning curriculum (h-PBL) were better at integrating basic science knowledge with clinical cases than students in a traditional, lecture-based curriculum (TC). The performance of TC students (n=40) was compared to that of h-PBL students (n=31). Participants read two clinical scenarios and answered a series of questions regarding each. To control for differences in ability, Dental Admission Test (DAT) Academic Average scores and predental grade point averages (GPAs) were compared, and an ANCOVA was used to adjust for the significant differences in DAT (t-test, p=0.002). Results showed that h-PBL students were better at applying basic science knowledge to a clinical case (ANCOVA, p=0.022) based on overall scores on one case. TC students' overall scores were better than h-PBL students on a separate case; however, it was not statistically significant (p=0.107). The h-PBL students also demonstrated greater skills in the areas of hypothesis generation (Mann-Whitney U, p=0.016) and communication (p=0.006). Basic science comprehension (p=0.01) and neurology (p<0.001) were two areas in which the TC students did score significantly higher than h-PBL students.

The purpose of this study was to investigate clinical characteristics and surgical management of Type III Wagstaffe fracture. From August 2012 to July 2015, 13 patients with Type III Wagstaffe fractures were surgically treated. During operation, the cartilage of joint surface was explored. Wagstaffe fragment was fixed with cannulated screw or suture, Chaput fragment was fixed with cannulated screw or plate, and Cotton test was performed to evaluate the stability of syndesmosis during the operation. All the patients were followed up for 14.3 months in average. Clinical outcome was assessed with Olerud-Molander score and American Orthopedic Foot and Ankle Society (AOFAS) score. The traumatic arthritis was evaluated with osteoarthritis-score (OA-score). During the operation, chondral injury was found on the lateral top of the talus in 8 cases, as "kissing lesion" of Chaput fragment. The fractures healed uneventfully and all the patients recovered satisfactorily except two had moderate restriction in ankle movement. The average Olerud-Molander score and AOFAS score were 82.3 and 86.1, respectively. Type III Wagstaffe is a rare and often missed fracture. 61% are associated with a chondral lesion on the lateral top of the talus. Anatomical reduction and rigid fixation of both fragments are mandatory to obtain ankle stability and good results. Copyright © 2017 European Foot and Ankle Society. Published by Elsevier Ltd.

Data on 1,700 patients pooled from 5 randomized, placebo-controlled duloxetine studies (3 in diabetic peripheral neuropathic pain and 2 in fibromyalgia) were analyzed to determine clinically important differences (CIDs) in the 0 to 10 Numeric Rating Scale-Pain Intensity (NRS-PI) for patient-reported "worst" and "least" pain intensity while validating the previously published level for "average" pain. The correspondence between the baseline-to-endpoint raw and percentage change in the NRS-PI for the worst, least, and average pain were compared to patients' perceived improvements at endpoint as measured by the 7-point Patient Global Impression of Improvement (PGI-I) scales. Stratification by baseline pain separated the raw but not the percent change scores. The PGI-I category of "much better" or above was our a priori definition of a CID. Cutoff points for the NRS-PI change scores were determined using a receiver operator curve analysis. A consistent relationship between the worst and average NRS-PI percent change and the PGI-I was demonstrated regardless of the study, pain type, age, sex, or treatment group with a reduction of approximately 34%. The least pain item CID was slightly higher at 41%. Raw change CID cutoff points were approximately -2, -2.5 and -3 for least, average, and worst pain respectively. We determined an anchor-based value for the change in the worst, least, and average pain intensity items of the Brief Pain Inventory that best represents a clinically important difference. Our findings support a standard definition of a clinically important difference in clinical trials of chronic-pain therapies. Copyright 2010 American Pain Society. Published by Elsevier Inc.

We are investigating the potential for differences in study conclusions when assessing the estimated impact of a computer-aided detection (CAD) system on readers' performance. The data utilized in this investigation were derived from a multi-reader multi-case observer study involving one hundred mammographic background images to which fixed-size and fixed-intensity Gaussian signals were added, generating a low- and high-intensity signal sets. The study setting allowed CAD assessment in two situations: when CAD sensitivity was 1) superior or 2) lower than the average reader. Seven readers were asked to review each set in the unaided and CAD-aided reading modes, mark and rate their findings. Using this data, we studied the effect on study conclusion of three clinically-based receiver operating characteristic (ROC) scoring definitions. These scoring definitions included both location-specific and non-location-specific rules. The results showed agreement in the estimated impact of CAD on the overall reader performance. In the study setting where CAD sensitivity is superior to the average reader, the mean difference in AUC between the CAD-aided read and unaided read was 0.049 (95%CIs: -0.027; 0.130) for the image scoring definition that is based on non-location-specific rules, and 0.104 (95%CIs: 0.036; 0.174) and 0.090 (95%CIs: 0.031; 0.155) for image scoring definitions that are based on location-specific rules. The increases in AUC were statistically significant for the location-specific scoring definitions. It was further observed that the variance on these estimates was reduced when using the location-specific scoring definitions compared to that using a non-location-specific scoring definition. In the study setting where CAD sensitivity is equivalent or lower than the average reader, the mean differences in AUC are slightly above 0.01 for all image scoring definitions. These increases in AUC were not statistical significant for any of the image scoring definitions. The results on the variance analysis differed from those observed in the other study setting. This investigation furthers our understanding of the relationships between non-localization-specific and localization-specific ROC assessment methodologies and their relevance to clinical practice.

The purpose of this study was to describe student performance on an OSCE in a physical diagnosis course. Cross-sectional study at Harvard Medical School, 1997-1999, for 489 second-year students. Average total OSCE score was 57% (range 39-75%). Among clinical skills, students scored highest on patient interaction (72%), followed by examination technique (65%), abnormality identification (62%), history-taking (60%), patient presentation (60%), physical examination knowledge (47%), and differential diagnosis (40%) (p <.0001). Among 16 OSCE stations, scores ranged from 70% for arthritis to 29% for calf pain (p <.0001). Teaching sites accounted for larger adjusted differences in station scores, up to 28%, than in skill scores (9%) (p <.0001). Students scored higher on interpersonal and technical skills than on interpretive or integrative skills. Station scores identified specific content that needs improved teaching.

A cross-sectional study was conducted to estimate the prevalence of clinical lameness in high-producing Holstein cows housed in 50 freestall barns in Minnesota during summer. Locomotion and body condition scoring were performed on a total of 5,626 cows in 53 high-production groups. Cow records were collected from the nearest Dairy Herd Improvement Association test date, and herd characteristics were collected at the time of the visit. The mean prevalence of clinical lameness (proportion of cows with locomotion score >or=3 on a 1-to-5 scale, where 1 = normal and 5 = severely lame), and its association with lactation number, month of lactation, body condition score, and type of stall surface were evaluated. The mean prevalence of clinical lameness was 24.6%, which was 3.1 times greater, on average, than the prevalence estimated by the herd managers on each farm. The prevalence of lameness in first-lactation cows was 12.8% and prevalence increased on average at a rate of 8 percentage units per lactation. There was no association between the mean prevalence of clinical lameness and month of lactation (for months 1 to 10). Underconditioned cows had a higher prevalence of clinical lameness than normal or overconditioned cows. The prevalence of lameness was lower in freestall herds with sand stalls (17.1%) than in freestall herds with mattress stall surfaces (27.9%). Data indicate that the best 10th percentile of dairy farms had a mean prevalence of lameness of 5.4% with only 1.47% of cows with locomotion score = 4 and no cows with locomotion score = 5.

The aim of the present study was to determine if acoustic measures of voice, characterizing specific spectral and timing properties, predict clinical ratings of depression severity measured in a sample of patients using the Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI-II). This is a prospective study. Voice samples and clinical depression scores were collected prospectively from consenting adult patients who were referred to psychiatry from the adult emergency department or primary care clinics. The patients were audio-recorded as they read a standardized passage in a nearly closed-room environment. Mean Absolute Error (MAE) between actual and predicted depression scores was used as the primary outcome measure. The average MAE between predicted and actual HAMD scores was approximately two scores for both men and women, and the MAE for the BDI-II scores was approximately one score for men and eight scores for women. Timing features were predictive of HAMD scores in female patients while a combination of timing features and spectral features was predictive of scores in male patients. Timing features were predictive of BDI-II scores in male patients. Voice acoustic features extracted from read speech demonstrated variable effectiveness in predicting clinical depression scores in men and women. Voice features were highly predictive of HAMD scores in men and women, and BDI-II scores in men, respectively. The methodology is feasible for diagnostic applications in diverse clinical settings as it can be implemented during a standard clinical interview in a normal closed room and without strict control on the recording environment.

Although reverse shoulder arthroplasty provides excellent clinical results in appropriately selected patients, loss of external and internal rotation may occur. Component selection, design, and placement affect postoperative results. Recent studies considered the effect of humeral component version on functional results. The current study investigated whether humeral stem retroversion affects the outcomes of reverse shoulder arthroplasty with a retrospective review of a multisurgeon, industry-sponsored, prospectively gathered database of a single reverse shoulder arthroplasty implant. All patients had at least 2-year follow-up. Clinical outcomes, including American Shoulder and Elbow Surgeons score, visual analog scale pain score, Short Form-12 Mental and Physical Component scores, range of motion, and internal rotation function, were compared between patients with humeral retroversion of 10° or less (group A) and those with humeral retroversion of 20° or greater (group B). Radiographic outcomes were compared. The analysis included 64 patients (group A, 29 patients; group B, 35 patients). No clinical or statistically significant difference was found in American Shoulder and Elbow Surgeons scores. Both groups showed statistical and clinical improvement vs preoperative scores, with group A averaging 77.8 and group B averaging 79.2 at final follow-up. No differences were found between groups in range of motion or ability to perform tasks that require shoulder internal rotation. Patients can expect good clinical improvement after reverse shoulder arthroplasty. No difference was found in clinical or radiologic outcomes based on humeral component retroversion. Despite the theoretical increase in external rotation when the humeral component is placed closer to native retroversion, the results did not show this effect. [Orthopedics. 2017; 40(3):179-186.].

The recent scientific reports have shown that angiogenesis can affect biological behavior of pathologic lesions. Regarding unique clinical outcome of Odontogenic keratocyst (OKC), the present study was aimed to compare angiogenesis in Odontogenic keratocyst and Dentigerous cyst (DC). In this experimental study, tissue sections of 46 samples of OKC and DC were stained through immunohistochemical method using Vascular Endothelial Growth Factor (VEGF) antibody. VEGF expression was evaluated in epithelial cells, fibroblasts and endothelial cells. The average percentage of stained cells in any samples was categorized to 3 groups as follows: SCORE 0: 10% of cells or less are positive. SCORE 1: 10 to 50% of cells are positive. SCORE 2: more than 50% of cells are positive. Mann-U-Whitney, T-test and chi-square was used for statistical analysis. The average of VEGF expression in 24 samples of DC was 20.2% and in 22 samples of OKC was 52.6%, respectively. The average of VEGF expression in these two cysts had statistical significant differences. (PV= 0.045). There was significant statistical differences between two cysts in the terms of VEGF SCORE (PV= 0.000). OKC samples had significantly higher SCORE for the purpose of VEGF incidence than DC. Also, there were no differences between VEGF expression in epithelial cells of two cysts (PV= 0.268) there were significant statistical differences between two cysts in terms of endothelial cell staining. The endothelial cell staining was significantly higher in OKC than DC (PV= 0.037%). Regarding higher expression of Vascular Endothelial Growth factor in OKC than DC, it seems that angiogenesis may have great impression on clinical outcome of OKC.

As radiologic assessment is a key part in evaluating patients visited in emergency department, this survey was conducted to measure emergency medicine residents' competency in choosing appropriate diagnostic imaging in different clinical scenarios. All emergency medicine residents enrolled in an academic emergency medicine discipline in the three medical universities of Tehran, Iran were recruited. A questionnaire was designed consisting of 10 clinically common scenarios selected from the American College of Radiology appropriateness criteria. Each resident completed the survey separately with answers only given after all residents participated. 196 residents completed the survey (95% of all residents). The results were stratified by post-graduate year and university. The average number of correct answers was 6.2. First, second and third year residents scored the average of 6.1, 5.8 and 6.5, respectively (P=0.04). The average score of residents from different universities did not differ significantly. According to the low average score, it is recommended that attentive educational perfections are needed to help residents order more appropriate diagnostic images, which may also be helpful for other healthcare providers. However, it seems that our emergency medicine academic curriculum is relatively efficient to enhance residents' skills in choosing proper imaging. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background: Clinical competency is one of the most important requirements in nursing profession, based on which nurses are assessed. To obtain an effective and improved form of clinical competency, several factors are observed and monitored by the health educational systems. Among these observed factors, spiritual intelligence is considered as one of the most significant factors in nurses’ success and efficacy. In this study, it is aimed to determine the spiritual intelligence status and its relationship with clinical competency. Materials and Methods: The descriptive–correlational research was carried out on 250 nurses in Mashhad educational hospitals, selected by multi-stage sampling. Demographic, clinical competency, and spiritual intelligence questionnaires were used for data collection and 212 questionnaires were analyzed. Results: About 53.3% of nurses obtained above average scores in spiritual intelligence. Clinical competency was evaluated by both self-evaluation and head nurse evaluation methods. Most nurses (53.8%) were having good level of clinical competency based on self-evaluation, 48.2% were at average level based on head nurse evaluation, and 53.3% were at average level based on overall score. A significant correlation was found between spiritual intelligence and clinical competency. Conclusions: In this study, the positive significant correlation between nurses’ spiritual intelligence and their clinical competency is investigated. Because of the positive effects of spiritual intelligence on nurses’ clinical competency and quality of care, it is recommended to develop nurses’ spiritual intelligence during their education and by way of continuous medical education.

To establish the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychologic battery as a valid measure of cognitive progression in Alzheimer disease (AD) by deriving annualized CERAD Total Change Scores and corresponding confidence intervals in AD and controls from which to define clinically meaningful change. Subjects included 383 normal control (NC) and 655 AD subjects with serial data from the CERAD registry database. Annualized CERAD Total Change Scores were derived and Reliable Change Indexes (RCIs) calculated to establish statistically reliable change values. CERAD Change Scores were compared with annualized change scores from the Mini-Mental State Examination (MMSE), Clinical Dementia Rating Scale (CDR) Sum of Boxes, and Blessed Dementia Rating Scale (BDRS). For the CERAD Total Score, the AD sample showed significantly greater decline than the NC sample over the 4-year interval, with AD subjects declining an average of 22.2 points compared with the NCs' improving an average 2.8 points from baseline to last visit [Group x Time interaction [F(4,1031)=246.08, P<0.001)]. By Visit 3, the majority of AD subjects (65.2%) showed a degree of cognitive decline that fell outside the RCI. CERAD Change Scores significantly correlated (P<0.001) with MMSE (r=-0.66), CDR (r=-0.42), and BDRS (r=-0.38) change scores. Results support the utility of the CERAD Total Score as a measure of AD progression and provide comparative data for annualized change in CERAD Total Score and other summary measures.

Cross-sectional. Clinical research center. Eighty-eight National Collegiate Athletic Association Division I incoming student-athletes (freshman and transfers). Participants completed baseline clinical concussion measures, including a neurocognitive test battery (CNS Vital Signs), a balance assessment [Sensory Organization Test (SOT)], and motivation testing (Rey Dot Counting). Participants granted permission to access hsGPA and SAT total score. Standard scores for each CNS Vital Signs domain and SOT composite score. Baseline motivation, hsGPA, and SAT explained a small percentage of the variance of complex attention (11%), processing speed (12%), and composite SOT score (20%). Motivation, hsGPA, and total SAT score do not explain a significant amount of the variance in neurocognitive and postural control measures but may still be valuable to consider when interpreting neurocognitive and postural control measures.

All laparoscopic antireflux procedures done by a single surgeon from November 1997 to October 2006 were retrospectively reviewed. Inclusion criteria were primary crural closure with pledgets and giant hiatal hernia (greater than one-third of the stomach in the chest by esophagram, greater than 5 cm in length endoscopically, or greater than one-third of the stomach in the chest operatively). We attempted to reach all patients who met inclusion criteria and administered the Reflux Symptom Index (RSI) and Quality of Life Scale for Gastroesophageal Reflux Disease (QLSGR) questionnaires. In total, 89 patients met inclusion criteria. The male-to-female ratio was 32:57. Average age was 62.7 years. Average body mass index was 29.3 kg/m(2). Average length of stay was 2 days, and mean clinic follow-up was 161 days. At the most recent follow-up, 62% of patients were asymptomatic. The most common postoperative symptoms were dysphagia (16%), reflux/emesis (5%), bloating (5%), nausea (4%), epigastric pain (4%), and heartburn (3%). There were six (6.7%) recurrences on esophagogastroduodenoscopy or upper gastrointestinal examination. Five patients with recurrence were symptomatic. Of the 89 patients, 29 (33%) completed the questionnaire, with a mean follow-up of 69.7 months. Average RSI score was 12 (maximum possible score, 45). In six of nine categories, the average score was less than 1 (possible score, 0-5). Average QLSGR score was 12 (maximum possible score, 45). For satisfaction with the present condition, the average score was 4.34 (maximum score, 5), and 82.7% of respondents were satisfied or very satisfied with their present condition. Laparoscopic primary repair of giant hiatal hernia provides excellent long-term results. We found that 62% of patients were asymptomatic at the last follow-up and that 82% of respondents were satisfied or very satisfied. The recurrence rate was 6.7%.

The number of systematic reviews published in the orthopaedic literature has increased, and these reviews can help guide clinical decision making. However, the quality of these reviews can affect the reader's ability to use the data to arrive at accurate conclusions and make clinical decisions. To evaluate the methodological and reporting quality of systematic reviews and meta-analyses in the sports medicine literature to determine whether such reviews should be used to guide treatment decisions. The hypothesis was that many systematic reviews in the orthopaedic sports medicine literature may not follow the appropriate reporting guidelines or methodological criteria recommended for systematic reviews. Systematic review. All clinical sports medicine systematic reviews and meta-analyses from 2009 to 2013 published in The American Journal of Sports Medicine (AJSM), The Journal of Bone and Joint Surgery (JBJS), Arthroscopy, Sports Health, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) were reviewed and evaluated for level of evidence according to the guidelines from the Oxford Centre for Evidence-Based Medicine, for reporting quality according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, and for methodological quality according to the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Analysis was performed by year and journal of publication, and the levels of evidence included in the systematic reviews were also analyzed. A total of 200 systematic reviews and meta-analyses were identified over the study period. Of these, 53% included evidence levels 4 and 5 in their analyses, with just 32% including evidence levels 1 and 2 only. There were significant differences in the proportion of articles with high levels of evidence (P < .001) and low levels of evidence (P = .005) by journal. The average PRISMA score was 87% and the average AMSTAR score was 73% among all journals. The average AMSTAR and PRISMA scores were significantly different by journal (P = .002 and .001, respectively) and by year (P = .046 and .019, respectively). Arthroscopy, AJSM, and JBJS all scored higher than Sports Health and KSSTA on the PRISMA and AMSTAR. The average PRISMA score by year varied from 85% to 89%, and the average AMSTAR score varied from 70% to 76%. Systematic reviews and meta-analyses in orthopaedics sports medicine literature relied on evidence levels 4 and 5 in 53% of studies over the 5-year study period. Overall, PRISMA and AMSTAR scores are high and may be better than those in other disciplines. Readers need to be conscious of potential shortcomings when reading systematic reviews and using them in practice. © 2015 The Author(s).

This study aimed to determine the relative strengths and weaknesses in language and verbal short-term memory abilities of school-age children who were adopted from Eastern Europe. Children adopted between 1;0 and 4;11 (years;months) of age were assessed with the Clinical Evaluation of Language Fundamentals-Preschool, Second Edition (CELF-P2) and the Clinical Evaluation of Language Fundamentals, Fourth Edition (CELF-4) at age 5 and ages 6-7. Language composites and subtests were compared across time. All CELF-P2 and CELF-4 mean scores fell in the average range. Receptive composites were 102.74 and 103.86, and expressive composites were 100.58 and 98.42, at age 5 and ages 6-7, respectively. Age of adoption did not correlate to test scores. At ages 6-7, receptive language, sentence formulation, and vocabulary were areas of strength, with subtest scores significantly better than test norms. Verbal short-term memory and expressive grammar subtest scores were within the average range but significantly worse than test norms. A high percentage of children scored 1 standard deviation below the mean on these 2 subtests (27.3%-34.1%). Eastern European adoptees had average scores on a variety of language tests. Vocabulary was a relative strength; enriching the environment substantially improved this language area. Verbal short-term memory and expressive grammar were relative weaknesses. Children learning a language later in life may have difficulty with verbal short-term memory, which leads to weaknesses in expressive syntax and grammar.

To compare the anesthetic effectiveness of 3 topical agents used for intravitreal injections. Randomized, triple-armed, double-blinded, prospective, single-centered trial in patients receiving intravitreal ranibizumab for neovascular age-related macular degeneration. Patients were randomized 1:1:1 to receive 0.5% tetracaine hydrochloride drops and a 4% lidocaine pledget (n = 31), 0.5% tetracaine hydrochloride drops alone (n = 31), or 4% cocaine (+ epinephrine 1/100,000) drops alone (n = 31). Patients were asked to score their pain experience using a visual analogue scale (VAS) immediately following and 15 minutes after their injection. The average of these scores was used as the primary outcome. The physician performing the procedure separately scored his perception of the patients' pain using the Wong-Baker FACES scale. Means of the averaged VAS pain score for Groups 1, 2, and 3 were: 19 (95% confidence interval [CI] 12-26), 21 (95% CI 13-29), and 21 (95% CI 16-27) respectively. Mean Wong-Baker pain scores for Groups 1, 2, and 3 were 1.9 (95% CI 1.3-2.6), 2.1 (95% CI 1.4-2.7), and 2.3 (95% CI 1.6-3.1) respectively. There was no significant difference (P = .549) between groups for average VAS pain score. Similarly, there was no significant difference (P = .790) for the physician-perceived pain score between groups. There was no clinical difference in patient pain experience between the 3 anesthetic options tested. The addition of a 4% lidocaine pledget offered no clinical advantage in pain relief compared to 0.5% tetracaine or 4% cocaine (+ epinephrine 1/100,000) drops alone. Copyright © 2011 Elsevier Inc.

Objectives To inform the rational deployment of assessor resource in the evaluation of applications to the UK Advisory Committee on Clinical Excellence Awards (ACCEA). Setting ACCEA are responsible for a scheme to financially reward senior doctors in England and Wales who are assessed to be working over and above the standard expected of their role. Participants Anonymised applications of consultants and senior academic GPs for awards were considered by members of 14 regional subcommittees and 2 national assessing committees during the 2014–2015 round of applications. Design It involved secondary analysis of complete anonymised national data set. Primary and secondary outcome measures We analysed scores for each of 1916 applications for a clinical excellence award across 4 levels of award. Scores were provided by members of 16 subcommittees. We assessed the reliability of assessments and described the variance in the assessment of scores. Results Members of regional subcommittees assessed 1529 new applications and 387 renewal applications. Average scores increased with the level of application being made. On average, applications were assessed by 9.5 assessors. The highest contributions to the variance in individual assessors' assessments of applications were attributable to assessors or to residual variance. The applicant accounted for around a quarter of the variance in scores for new bronze applications, with this proportion decreasing for higher award levels. Reliability in excess of 0.7 can be attained where 4 assessors score bronze applications, with twice as many assessors being required for higher levels of application. Conclusions Assessment processes pertaining in the competitive allocation of public funds need to be credible and efficient. The present arrangements for assessing and scoring applications are defensible, depending on the level of reliability judged to be required in the assessment process. Some relatively minor reconfiguration in approaches to scoring might usefully be considered in future rounds of assessment. PMID:27256095

Introduction Fatigue is a common symptom in RA and used as an outcome measure in RA clinical trials. We studied a large academic clinical practice to estimate the minimally important difference (MID) for a fatigue visual analog scale using patient-reported anchors (fatigue, pain and overall health). Methods RA patients (N=307) had clinic visits at 2 time points at a median of 5.9 months apart. They completed fatigue visual analog scale (VAS; 0–10) and retrospective anchor items, “How would you describe your overall fatigue/pain/overall health since the last visit?” Much worsened, Somewhat worsened, Same, Somewhat better, or Much better. The fatigue anchor was used for primary analysis and the pain/ overall health anchors for sensitivity analyses. The minimally changed group was defined by those reporting they were somewhat better or somewhat worsened. Results The mean (SD) age was 59.4 (13.2) years, disease duration was 14.1 (11.5) years, and 83% of patients were women. The baseline mean (SD) HAQ-DI score was 0.84 (0.75). The baseline fatigue VAS score was 4.2 (2.9) and at follow up was 4.3 (2.8) (mean change of −0.07 [2.5], p=NS). The fatigue change score (0–10 scale) for somewhat better and somewhat worsened for fatigue anchor averaged −1.12 and 1.26, respectively. Using pain anchor, the fatigue changed score for somewhat better and somewhat worsened averaged −0.87 and 1.13 and using global anchor, the fatigue changed score for somewhat better and somewhat worsened averaged −0.82 and 1.17, respectively. Effect size (ES) estimates using 3 anchors were small for somewhat better (range: 0.27 to 0.39) and somewhat worsened (range: 0.40 to 0.44) groups but larger than the no-change group (range: 0.03 to 0.08). Conclusions The MID for fatigue VAS is between −0.82 to −1.12 for improvement and 1.13 to 1.26 for worsening on 0–10 scale in a large RA clinical practice and similar to that seen in RA clinical trials. This information can aid in interpreting fatigue VAS in day-to-day care in clinical practice. PMID:19004044

To evaluate the clinical outcomes of three-dimensional (3D) transfer of the tibial tuberosity for patellar instability with patella alta, with a focus on the influence of age at initial surgery. Three-dimensional surgery was performed on 28 knees with a mean follow-up of 46 months. Patients were separated into three groups based on the age at initial surgery: group A, 10 knees and an average age of 16.3 ± 1.8 (14-19) years; group B, 10 knees and an average age of 22.1 ± 2.5 (20-28) years; and group C, eight knees and an average age of 44.0 ± 2.2 (40-46) years. Patellofemoral geometry improvement focused on patella alta by determining the Insall-Salvati ratio and Caton-Deschamps index, rotational malalignment by measuring the tibial tubercle-trochlear groove (TT-TG) distance, and lateral patellar subluxation by measuring the patellar tilt. Clinical outcomes were evaluated by the Lysholm and Kujala scores, which were compared before and after surgery. Cartilage degeneration was evaluated by the International Cartilage Repair Society grading system at initial arthroscopy. The patellar height, TT-TG, and patellar tilt significantly improved in all groups postoperatively (p < 0.05). The Lysholm and Kujala scores also significantly improved postoperatively; however, both scores were lower in group C than in the other groups (p < 0.05). Particularly, pain scores were more severe in group C than in the other groups, and the severity of cartilage degeneration correlated with the pain scores (p < 0.05). Cartilage damage differed significantly between the groups at initial arthroscopy; particularly, group C included grades III and IV cartilage degeneration (p < 0.05). Age at initial surgery may be the predicting factor for poor clinical outcomes of 3D transfer surgery. The clinical outcome may depend on the age at surgery, which correlated with cartilage damage; thus, surgeons should be given this information when patients are considered undergoing patella surgery.

Objective The purpose of this study was to examine the relationships among depressive symptoms, stress and severity of binge eating symptoms in a community sample of African American and Hispanic or Latina women. Method Women (African American n=127, Hispanic or Latina n=44) completed measures of body composition, stress, depression, and binge eating. Results Scores on a depressive symptom scale indicated that 24.0% of participants exhibited clinically significant levels of depressive symptoms. Mean binge eating scores were below the threshold for clinically diagnosed binge eating (12.99±7.90). Mean stressful event scores were 25.86±14.26 and the average stress impact score was 78.36±55.43. Linear regression models found that body composition, stress impact score, and being classified as having clinically significant levels of depression, were associated with severity of binge eating symptoms. Conclusion Higher levels of percent body fat, a CES-D score ≥16 and higher WSI-Impact scores were associated with greater severity of binge eating symptoms. PMID:23760851

Manual scoring of polysomnograms is a time-consuming and tedious process. To expedite the scoring of polysomnograms, several computerized algorithms for automated scoring have been developed. The overarching goal of this study was to determine the validity of the Somnolyzer system, an automated system for scoring polysomnograms. The analysis sample comprised of 97 sleep studies. Each polysomnogram was manually scored by certified technologists from four sleep laboratories and concurrently subjected to automated scoring by the Somnolyzer system. Agreement between manual and automated scoring was examined. Sleep staging and scoring of disordered breathing events was conducted using the 2007 American Academy of Sleep Medicine criteria. Clinical sleep laboratories. A high degree of agreement was noted between manual and automated scoring of the apnea-hypopnea index (AHI). The average correlation between the manually scored AHI across the four clinical sites was 0.92 (95% confidence interval: 0.90-0.93). Similarly, the average correlation between the manual and Somnolyzer-scored AHI values was 0.93 (95% confidence interval: 0.91-0.96). Thus, interscorer correlation between the manually scored results was no different than that derived from manual and automated scoring. Substantial concordance in the arousal index, total sleep time, and sleep efficiency between manual and automated scoring was also observed. In contrast, differences were noted between manually and automated scored percentages of sleep stages N1, N2, and N3. Automated analysis of polysomnograms using the Somnolyzer system provides results that are comparable to manual scoring for commonly used metrics in sleep medicine. Although differences exist between manual versus automated scoring for specific sleep stages, the level of agreement between manual and automated scoring is not significantly different than that between any two human scorers. In light of the burden associated with manual scoring, automated scoring platforms provide a viable complement of tools in the diagnostic armamentarium of sleep medicine. © 2015 Associated Professional Sleep Societies, LLC.

Although total knee arthroplasty has a high success rate, poor outcomes and early revision are associated with ligament imbalance. This multicenter evaluation was performed in order to provide 1-year followup of a previously reported group of patients who had sensor-assisted TKA, comparing the clinical outcomes of quantitatively balanced versus unbalanced patients. At 1 year, the balanced cohort scored 179.3 and 10.4 in KSS and WOMAC, respectively; the unbalanced cohort scored 156.1 and 17.9 in KSS and WOMAC (P < 0.001; P = 0.085). The average activity level scores of quantitatively balanced patients were 68.6 (corresponding to tennis, light jogging, and heavy yard work), while the average activity level of unbalanced patients was 46.7 (corresponding to light housework, and limited walking distances) (P = 0.015). Out of all confounding variables, a balanced articulation was the most significant contributing factor to improved postoperative outcomes (P < 0.001). PMID:25210632

To evaluate the usefulness of separate vertical wirings for extra-articular fracture of distal pole of patella. We have analyzed the clinical results of 18 cases that underwent separate vertical wirings for extra-articular fracture of distal pole of the patella from March 2005 to March 2010, by using the range of motion and Bostman score. Occurrence of complication was also evaluated. Additionally, by taking simple radiographs, the correlation between the postoperative degree of anterior transposition of bone fragment and the time of bone fusion, preoperative length of bone fragment, and occurrence of comminuted fracture were investigated. It took an average of 13.8 weeks for radiological bone union after separate vertical wiring fixation. Flexion contracture was an average of 0.8 degrees and further flexion was an average of 127.6°, and Bostman score was an average of 27.5 points (excellent in 12 cases, and good in 6 cases). On the first postoperative year, average flexion contracture was 0.6 degrees and further flexion was an average of 136.3°, which exhibited increased joint motion and recovery to normal range of motion, and Bostman score was an average of 28.7 points (excellent in 16 cases, and good in 2 cases). There was no statistically significant difference between the preoperative bone fragment length and presence of comminution, and degree of anterior transposition of bone fragment after fracture union on simple radiograph (p=0.175, p=0.146). We were able to obtain satisfactory clinical results, while preserving the bone fragment by separate vertical wiring fixation for extra-articular fracture of distal pole of patella. Moreover, the method is easy to perform, which is also considered as a useful surgical method for extra-articular fracture of distal pole of patella.

Abstract The current ethical dilemmas met by healthcare professionals were never compared with those 15 years ago when the palliative care system was newly developing in Taiwan. The aim of the study was to investigate the ethical dilemmas met by palliative care physicians and nurses in 2013 and compare the results with the survey in 1998. This cross-sectional study surveyed 213 physicians and nurses recruited from 9 representative palliative care units across Taiwan in 2013. The compared survey in 1998 studied 102 physicians and nurses from the same palliative care units. All participants took a questionnaire to survey the “frequency” and “difficulty” of 20 frequently encountered ethical dilemmas, which were grouped into 4 domains by factor analysis. The “ethical dilemma” scores were calculated and then compared across 15 years by Student's t tests. A general linear model analysis was used to identify significant factors relating to a high average “ethical dilemma” score in each domain. All of the highest-ranking ethical dilemmas in 2013 were related to insufficient resources. Physicians with less clinical experience had a higher average “ethical dilemma” score in clinical management. Physicians with dissatisfaction in providing palliative care were associated a higher average “ethical dilemma” score in communication. Nurses reported higher “ethical dilemma” scores in all items of resource allocation in 2013. Further analysis confirmed that, in 2013, nurses had a higher average “ethical dilemma” score in resource allocation after adjustment for other relating factors. Palliative care nursing staff in Taiwan are more troubled by ethical dilemmas related to insufficient resources than they were 15 years ago. Training of decision making in nurses under the framework of ethical principles and community palliative care programs may improve the problems. To promote the dignity of terminal cancer patients, long-term fundraising plans are recommended for countries in which the palliative care system is in its early stages of development. PMID:26735533

Incapacitating chronic migraine and other severe headaches can have significant impact on peoples' lives, including family and occupational functioning. Although a number of reports have investigated the prevalence and medical treatment of chronic headache, few have reported on the efficacy of treating these disorders within a comprehensive, intensive chronic pain rehabilitation program (CPRP), instead of a headache-specific program. CPRPs provide treatment of headache by focusing not only on physical pain, but also its association with impaired mood and function. We examined the efficacy of CPRP in patients with chronic headache via a retrospective analysis of 123 patients (76.4% female), ages 21 to 85, who completed the CPRP at the Cleveland Clinic between January 2007 and December 2011, and were diagnosed using International Classification of Headache Disorders, 2nd edition and International Classification of Headache Disorders, 2nd edition revision, with migraine or headache as a major complaint. Outcome measures included: pain intensity scores present at the moment of questioning where 10 is the maximal (0-10/10), Depression Anxiety Stress Scale (DASS) scores, (measuring mood), and Pain Disability Index scores (measuring function). Repeated measures t-tests were used. Average pain score on admission was 6.4, and 3.4 upon discharge. Average function on admission was moderately impaired, and normalized on discharge. The average depression score was in the moderate range, and had normalized on discharge. The average anxiety score on admission was in the severe range and was in the mild range on discharge. Results indicate that individuals had statistically and clinically meaningful improvement in pain, mood, and function. Data suggest that an interdisciplinary CPRP approach for patients diagnosed with headache can be effective in helping to decrease pain, as well as normalize mood and function. Thus, CPRPs serve as an alternative treatment to multidisciplinary headache programs, interventional pain techniques, and primary care standard headache care. © 2013 American Headache Society.

The purpose of this study was to explore the midterm clinical outcomes of unicompartmental knee replacement (UKR) for medial knee arthropathy through a minimally invasive approach (MIA). From January 2006 to June 2010, 442 consecutive patients (485 knees) were included in the study. All patients underwent MIA-UKR with the mobile bearing Oxford phrase III prosthesis. The incision was made starting 1 cm medial to the medial pole of the patella and extending distally to the tibial tubercle. Radiographic evaluations include femorotibial angle (FTA) from coronal x-rays and rectified varus deformity angle, while clinical evaluations included Knee Society Score (KSS, clinical score and function score), the Western Ontario and McMaster Universities Arthritis Index (WOMAC) osteoarthritis index and visual analog scale (VAS) for pain. Patients followed-up at 1, 3, 6, 12 months after surgery and each year thereafter. Four hundreds and two patients completed the entire follow-up, 40 patients (45 knees) were lost to follow-up. The average follow-up time was 73.0 ± 1.9 months. The mean length of the incisions was 5.0 ± 0.2 cm. The average FTA decreased from 183.6° ± 5.1° preoperatively to 174.3° ± 4.2° postoperatively, and the mean rectified varus deformity angle was 9.3° ± 1.2°. The KSS clinical score improved from 42.4 ± 2.9 to 92.9 ± 3.8, and the function score improved from 53.5 ± 3.8 to 93.5 ± 4.0. The WOMAC score improved from 47.5 ± 3.1 preoperatively to 12.3 ± 1.5 at the last evaluation. The VAS dropped from 7.8 ± 1.9 preoperatively to 1.6 ± 0.2 postoperatively. All clinical evaluations (KSS, WOMAC, VAS) were significantly different (p < 0.05) from pre and post-operative evaluations. The survival rate was 99.1% at 73 months, and the revision rate was 0.9%. The midterm clinical outcomes of MIA-UKR are satisfactory in a Chinese patient population, which is a good surgical option for patients with medial arthropathy of the knee. However, longer-term follow-up studies should be performed in these patients.

The purpose of this study was to assess the efficacy of two different BriteSmile hydrogen peroxide (H2O2) gels in a split-arch protocol for whitening teeth in a clinical setting when used in conjunction with a BriteSmile BS4000 lamp. Fifteen subjects were enrolled into a single-center clinical trial. The efficacy of the BriteSmile BS4000 lamp using both 15% H2O2 and 25% H2O2 gel formulations was tested. Study subjects were concurrently exposed to the whitening lamp with the 15% H2O2 gel placed on half of their anterior teeth and the 25% H2O2 gel on the other half for a total light and gel exposure of 60 minutes. The clinical data collected were shade score, gingival health, and dentinal hypersensitivity self-assessment. Changes in tooth shade were better for subjects exposed to the 25% gel and the dental whitening lamp (average 8.0 shade changes) compared to subjects exposed to the 15% gel and dental whitening lamp (average 7.6 shade changes) immediately after treatment. The same held true at the 7-day follow-up (25% gel average 7.4 shade changes versus 15% gel average 7.3 shade changes). However, these differences were not statistically significant. No reports of irritation of gingival soft tissues were documented. The relative changes in mean sensitivity scores were similar for both groups with no significant differences in mean sensitivity scores between the groups. Both concentrations of H2O2 gel and the whitening lamp combined gave study subjects an average of 8.0 (25% gel) and 7.6 (15% gel) shade changes immediately after treatment. The 7-day follow-up examination resulted in a regression of lightest to an average of 7.4 (25% gel) and 7.3 (15% gel). It was concluded that the use of the chairside whitening light and either 15% or 25% hydrogen peroxide gel is safe and effective for whitening teeth in 1 hour.

To investigate surgical skills and clinical effects of manipulative reduction and percutaneous Kirschner wire internal fixation in treating grade IV supination-external rotation ankle fractures. From May 2013 to October 2016, 35 patients with grade IV supination-external rotation ankle fractures were treated with percutaneous Kirschner wire internal fixation, involving 22 males and 13 females with an average age of 38.2 years ranged from 18 to 65 years old. The time from injury to operation ranged from 2 h to 10 d with an average of 5 d. Reduction quality was assessed by Burwell-Charnley radiological criteria. Baird-Jackson ankle scoring system was used to assess clinical effects. Thirty-three patients were followed up from 10 to 28 months with an average of 14 months. Fracture healing time ranged from 10 to 18 weeks with an average of 12 weeks. According to Burwell-Charnley radiological criteria, 30 cases were obtained anatomic reduction, 3 cases moderate. According to Baird-Jackson ankle scoring system, total score was 93.8±5.4, 17 cases got excellent result, 12 good, 2 fair and 2 poor. Manipulative reduction and percutaneous Kirschner wire internal fixation in treating grade IV supination-external rotation ankle fractures has advantages of reliable efficacy, less complications. But higher require techniques were required for closed reduction. It is not suitable for severe crushed fracture and compressive articular surface fracture.

This analysis explored the relationship between ratings on HAM-D-17 or YMRS and those on the depressive or manic subscale of CGI-S for schizoaffective disorder (CGI-S-SCA). This post hoc analysis used the database (N=614) from two 6-week, randomized, placebo-controlled studies of paliperidone ER versus placebo in symptomatic subjects with schizoaffective disorder assessed using HAM-D-17, YMRS, and CGI-S-SCA scales. Parametric and nonparametric regression models explored the relationships between ratings on YMRS and HAM-D-17 and on depressive and manic domains of the CGI-S-SCA from baseline to the 6-week end point. A clinically meaningful improvement was defined as a change of 1 point in the CGI-S-SCA score. No adjustment was made for multiplicity. Multiple linear regression models suggested that a 1-point change in the depressive domain of CGI-S-SCA corresponded to an average 3.6-point (SE=0.2) change in HAM-D-17 score. Similarly, a 1-point change in the manic domain of CGI-S-SCA corresponded to an average 5.8-point (SE=0.2) change in YMRS score. Results were confirmed using local and cumulative logistic regression models in addition to equipercentile linking. Lack of subjects scoring over the complete range of possible scores may limit broad application of the analyses. Clinically meaningful score changes in depressive and manic domains of CGI-S-SCA corresponded to approximately 4- and 6-point score changes on HAM-D-17 and YMRS, respectively, in symptomatic subjects with schizoaffective disorder.

To study the clinical efficacy of sacral manual therapy in the treatment of coccygodynia. From November 2013 to July 2015, 184 patients with sacrococcygeal pain were divided into treatment group and control group. There were 26 males and 65 females in the treatment group, with an average age of (39.63±11.62) years old. In the control group, there were 31 males and 62 females, with an average age of (41.47±11.56) years old. The patients in the treatment group were treated with sacrococcygeal massage therapy, 3 times a week for 2 weeks. The patients in the control group were treated with Diclofenac Diethylamine Emulgel, 2 times a day for 2 weeks. The VAS pain score, score in rating scale of sacrococcygeal pain and degree of tenderness were obtained on the first day of treatment, 2, 7, 14 days and 3 months after treatment to evaluate clinical results. When comparing the VAS pain score of sacrococcygeal pain within the two groups, the differences began to reach statistical significance on the second day( P <0.001). The chagne of VAS pain scores, the change of scores in rating scale of sacrococcygeal pain and the degree of tenderness in the treatment group were all significontly larger that those in the contral group from the second day. The curative effect of sacral manipulation group is better than that of Diclofenac Diethylamine Emulgel group in the treatment of sacrococcygeal pain.

The Global Assessment of Functioning (GAF) Scale is used in routine clinical practice and research to estimate symptom and functional severity and longitudinal change. Concerns about poor interrater reliability have been raised, and the present study evaluated the effect of a Web-based GAF training program designed to improve interrater reliability in routine clinical practice. Clinicians rated up to 20 vignettes online, and received deviation scores as immediate feedback (i.e., own scores compared with expert raters) after each rating. Growth curves of absolute SD scores across the vignettes were modeled. A linear mixed effects model, using the clinician's deviation scores from expert raters as the dependent variable, indicated an improvement in reliability during training. Moderation by content of scale (symptoms; functioning), scale range (average; extreme), previous experience with GAF rating, profession, and postgraduate training were assessed. Training reduced deviation scores for inexperienced GAF raters, for individuals in clinical professions other than nursing and medicine, and for individuals with no postgraduate specialization. In addition, training was most beneficial for cases with average severity of symptoms compared with cases with extreme severity. The results support the use of Web-based training with feedback routines as a means to improve the reliability of GAF ratings performed by clinicians in mental health practice. These results especially pertain to clinicians in mental health practice who do not have a masters or doctoral degree. (c) 2015 APA, all rights reserved.

The tethered cord syndrome (TCS) characterized by urination dysfunction has long been a worldwide clinical problem, of which clinical effects remains controversial. The objective of this study was to evaluate the clinical effects of an innovative surgical method for the treatment of TCS. This is a retrospective clinical study. There were 15 patients included in this study. The visual analog scale (VAS) and the Japanese Orthopaedic Association (JOA) scores were evaluated. The incidence of complications after surgery was also analyzed. A total of 15 patients including 9 men and 6 women with TCS underwent homogeneous spinal-shortening axial decompression (HSAD) from September 2011 to February 2015. The average age at the time of surgery was 38.1±17.7 years. The average postoperative follow-up period was 21.5±7.5 months. The VAS and JOA scores were used to evaluate the clinical effects of the new operational procedure. In addition, the incidence of complications was also recorded and analyzed. The VAS scores decreased from 3.93±2.52 to 1.80±1.21 at the final follow-up after surgery with a significant statistical difference (p=.006). The JOA scores also significantly increased from 9.93±3.43 to 21.20±4.18 at the final follow-up (p<.001). Fourteen cases (93.3%) with bladder dysfunction and 7 cases with sensory dysfunction of the lower limbs (87.5%) had a significant improvement postoperatively. Complications such as infection, pulmonary embolism, nerve injury, and broken rod were not observed during the follow-up period. The operation of HSAD was an effective and safe surgical method for TCS, which can achieve direct decompression of the tethered spinal cord. Copyright © 2017. Published by Elsevier Inc.

To offer individualized restorative strategies for patients receiving dental implants in the anterior esthetic zone but with inappropriate available conditions and evaluate the clinical outcomes. Forty-six patients with 58 implants were recruited for the study in accordance with the criteria and received individualized implant prostheses in the anterior esthetic zone. The patients were followed up for 3-24 months, and the clinical outcomes were evaluated by pink and white esthetic scores (PES/WES). The patients were from 18 to 69 years old, and followed up for 12.6 months in average. According to the third month follow-up esthetic scores, for PES, 1.72% of the patients got low scores, 44.83% got medium scores and 53.45% got high scores; For WES, 0% got low scores, 20.69% got medium scores and 79.31% got high scores. No implant failure or peri-implantitis occurred. Individualized restorative designs for implants in the esthetic zone can effectively improve the appearance of the prostheses which originally have no appropriate available space. Close follow-up and monitoring of the peri-implant soft tissue and proper oral hygiene instructions are important to ensure the conditions of the prostheses.

Finding ways to improve communication and self-reflection skills is an important element of medical education and continuing professional development. This study examines the relationship between self-reflection and educational outcomes. We correlate performance in a preclinical course that focuses on self-reflection as it relates to contextual elements of patient care (Human Context of Health Care), with educational measures such as overall grade point average, clinical clerkship scores, and Medical College Admission Test (MCAT) scores. Student performance in Human Context of Health Care correlated with MCAT-Verbal scores, MCAT-writing sample scores, clerkship grades, and overall medical school grade point average (R = 0.3; p < 0.001). Writing and self-reflection skills are often neglected in undergraduate medical curricula. Our findings suggest that these skills are important and correlate with recognized long-term educational outcomes.

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 leads to statistically significant midterm improvement in ROM and satisfactory midterm subjective outcome scores with low complication/failure rates in patients with average medium-sized rotator cuff tears with minimal fatty infiltration. Further work is required to evaluate radiographic healing rates with this technique and to compare outcomes following suture anchor repair. Level of Evidence: Level IV PMID:26980983

Clinical Indicators of Psychosocial Distress Predict for Acute Radiation-Induced Fatigue in Patients Receiving Adjuvant Radiation Therapy for Breast Cancer: An Analysis of Patient-Reported Outcomes

Kishan, Amar U.; Wang, Pin-Chieh; Sharif, Jamal

Purpose: To assess the magnitude and predictors of patient-reported fatigue among breast cancer patients receiving radiation therapy (RT). Methods and Materials: Patients receiving breast RT completed a survey querying fatigue at each weekly on-treatment visit. Patient-reported fatigue severity and interference was assessed on an ordinal scale of 0 to 4, using a validated scoring system. Baseline anxiety and depression scores were also obtained. The kinetics of mean fatigue scores per week and the maximum fatigue scores over the course of the entire treatment were assessed, and clinical predictors were identified by univariate and multivariate regression. Results: The average fatigue severitymore » and interference scores were 0.6 and 0.46. The average fatigue scores increased to an equivalent extent from week to week, with expected increases of 0.99 in fatigue severity and 0.85 in interference over 7 weeks. Patients treated with hypofractionated RT (HF-RT) versus conventionally fractionated RT (CF-RT) had significantly fewer maximum fatigue severity or interference scores that were >2 (ie, severe or very severe; 29% vs 10% for severity, and 26% vs 8% for interference, P<.01). Age ≤45 years, presence of psychiatric/pain-related comorbidities, and baseline sadness and anxiety severity were predictive of average and maximum fatigue scores (P<.05), but variables related to treatment intensity (eg, mastectomy vs lumpectomy, chemotherapy use, radiation target volumes) and other host factors (working, children, marital status, proximity to RT facility) were not. Conclusion: Patient-reported fatigue modestly increases over RT courses, with less maximum fatigue reported with HF-RT. Younger age and baseline sadness, anxiety, and psychiatric/pain-related comorbidities are powerful predictors of fatigue, whereas other factors, such as treatment intensity, are not. Future studies will investigate interventions for patients at high risk for fatigue.« less

Despite the perceived importance of sleep for athletes, little is known regarding athlete sleep quality, their prevalence of daytime sleepiness or risk factors for obstructive sleep apnoea (OSA) such as snoring and witnessed apnoeic episodes. The purpose of the present study was to characterise normative sleep quality among highly trained team sport athletes. 175 elite or highly trained rugby sevens, rugby union and cricket athletes completed the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Score (ESS) and Quality of Life questionnaires and an OSA risk factor screen. On average, athletes reported 7.9 ± 1.3 h of sleep per night. The average PSQI score was 5.9 ± 2.6, and 50% of athletes were found to be poor sleepers (PSQI > 5). Daytime sleepiness was prevalent throughout the population (average global score of 8.5) and clinically significant (ESS score of ≥10) in 28% of athletes. OSA may be an important clinical consideration within athletic populations, as a considerable number of athletes (38%) defined themselves as snorers and 8% reported having a witnessed apnoeic episode. The relationship between self-rated sleep quality and actual PSQI score was strong (Pearson correlation of 0.4 ± 0.1, 90% confidence limits). These findings suggest that this cohort of team sport athletes suffer a preponderance of poor sleep quality, with associated high levels of daytime sleepiness. Athletes should receive education about how to improve sleep wake schedules, extend total sleep time and improve sleep quality.

Background. Lyme disease is the most common vector-borne disease in the United States. Some patients report persistent or intermittent subjective symptoms of mild to moderate intensity after antibiotic treatment for Lyme disease. We sought to evaluate trends in clinical and quality-of-life (QOL) measures in a cohort of patients with Lyme disease enrolled in a natural history study at the National Institutes of Health from 2001–2014. Methods. QOL was measured using the self-administered 36-item Short Form Health Survey (SF-36) during study follow-up. Primary outcomes included mean physical (PCS) and mental (MCS) health QOL composite scores and reporting long-term (≥2 years) symptoms, adjusted for Lyme disease stage and severity at diagnosis. Results. Overall, 101 patients with an average follow-up time of 3.9 years (range, 0.5–11.3 years) were included. At first visit, overall mean QOL scores were below the US population mean for both PCS (45.6 ± 10.4) and MCS (47.3 ± 11.5) but increased to just above the national average after 3 years of follow-up for both PCS (50.7 ± 9.6) and MCS (50.1 ± 10.0). Baseline QOL scores were lowest in those with late disease (P < 0.01) but also increased by the end of follow-up to national averages. In multivariate analysis, the only factors significantly associated with long-term symptoms or lower QOL scores were other comorbidities unrelated to Lyme disease. Conclusions. Comorbid conditions can play a role in the reporting of long-term symptoms and overall QOL of Lyme disease patients and should be considered in the evaluation of these patients.

Abstract Interpersonal and communication skills are 2 essential qualities of every physician. These are separate and distinct parts of the professional character of every physician. In pediatrics these abilities present even a higher impact. We performed a survey-type prospective study based on questionnaires on 100 subjects, equally divided into 4 groups: 25 children, 25 pediatricians, 25 care-givers (parents, tutors, and relatives), and 25 health care staff, in a Tertiary Pediatric Clinic from Romania, between January 2017 and April 2017. We included 100 participants in our study, equally divided into 4 groups: pediatric patients, pediatricians, care-givers, and health care staff. The 1st group comprised 25 children diagnosed with different chronic conditions, presenting the age between 5 and 14 years. The male gender predominated among the children (57%). The lowest general average score for “Communication” section was encountered among pediatricians group, 3.8, while the other 3 groups presented the same average score for this section, that is, 4.6. The children and the health care staff offered the same average score for “Transparency,” that is, 4.6, while the pediatricians offered a score of 4.5, and the care-givers of 4.7. The lowest average score for the item “Hospital environment” was given by the doctors, that is, 3.3, followed by care-givers with a score of 3.6, health care staff 3.7, and children with an average score of 3.8. All the 4 groups included in the study offered a general average of 4.9 out of 5 for the “Intercultural issues” section. The lowest average score for “Time management” section was offered by both children and pediatricians, that is, 4.1, while care-givers and health care staff had a slightly better perception regarding this item, offering 4.2 and 4.3, respectively. The opinion among the 4 groups included in the study was generally similar regarding the 5 items assessed by our questionnaires. Therefore, the main aspects that need to be improved in the health care system in downward order are the following: hospital environment, time management, communication, transparency, and intercultural issues.

Background Failed fusion surgery remains difficult to treat. Few published data on disc replacement surgery after failed fusion procedures exist. Our objective was to evaluate outcomes of junctional lumbar disc replacement after previous fusion surgery and to correlate outcome with radiological changes to parameters of sagittal balance. Methods Out of a single-center prospective registry of 290 patients with 404 lumbar disc replacements, 27 patients had had a previous lumbar fusion operation on 1 to 4 lumbar segments and had completed a mean follow- up of 33 months (range: 18–56). We correlated the clinical outcome measures (patient satisfaction, 10-point pain score, and Oswestry Disability Index [ODI] score) to parameters of spinal sagittal alignment (sacral tilt, pelvic tilt, pelvic incidence, and lumbar lordosis). Results Postoperative hospital stay averaged 3.3 days (range: 2–8). Previously-employed patients went back to their jobs with a mean of 32 days (range: 21–42) after the procedure. At the latest follow-up, 1 of the patients considered the outcome to be poor, 3 fair, 8 good, and 15 excellent. Twenty-four patients “would undergo the operation again.” Average pain score decreased from 9.1 ± 1.0 (SD) to 3.2 ± 2.1 (P < .01). Average ODI decreased from 50.2 ± 9.9 preoperatively to 21.7 ± 14.2 (P ≤ .01). We found the change in pelvic tilt to be an independent predictor of better clinical outcome by multivariate analysis (P < .05). Conclusions In patients with junctional failure adjacent to a previous posterolateral fusion, disc replacement at the junctional level(s), compared with osteotomy and fusion surgery, offers the advantage of maintaining segmental mobility and correcting the flat-back deformity through a single approach with less operative time and blood loss. Early- to intermediate-term results are promising. The influence of changes in spinal sagittal alignment on clinical outcome needs to be addressed in future research. Clinical Relevance This is the first study on “junctional disc replacement patients” correlating clinical outcome to changes in spinal/pelvic alignment. PMID:25802584

A novel program for clinical pathology training for residents emphasizing high-impact and attending-level learning opportunities.

Ranheim, Erik A

2014-02-01

Clinical pathology (CP) rotations in our residency program consistently received lower evaluations and lower scores on the Resident In-Service Exam (RISE) in comparison to anatomic pathology rotations. In 2010 to 2011, we instituted a new model for CP training, wherein the separate rotations for chemistry, transfusion medicine, molecular diagnostics, microbiology, and coagulation/immunology were combined into a 3-month "Superblock" in an effort to maximize and repeat high-impact learning opportunities in a team-based model. Resident and faculty satisfaction with the new curriculum and RISE scores were assessed in the 3 years before and after implementation of the curriculum. Large majorities of residents and faculty expressed increased satisfaction with the curriculum. Average RISE scores increased 8.3% in CP in the 3 years following introduction of the curriculum compared to the 3 years prior to introduction, while anatomic pathology average scores decreased by 1.5%. The CP Superblock provides a model of CP education which may address some of the difficulties in teaching CP topics and recruiting residents to CP specialization. The pros and cons of its implementation are discussed. © 2014.

Application of new WAIS-III/WMS-III discrepancy scores for evaluating memory functioning: relationship between intellectual and memory ability.

PubMed

Lange, Rael T; Chelune, Gordon J

2006-05-01

Analysis of the discrepancy between memory and intellectual ability has received some support as a means for evaluating memory impairment. Recently, comprehensive base rate tables for General Ability Index (GAI) minus memory discrepancy scores (i.e., GAI-memory) were developed using the WAIS-III/WMS-III standardization sample (Lange, Chelune, & Tulsky, in press). The purpose of this study was to evaluate the clinical utility of GAI-memory discrepancy scores to identify memory impairment in 34 patients with Alzheimer's type dementia (DAT) versus a sample of 34 demographically matched healthy participants. On average, patients with DAT obtained significantly lower scores on all WAIS-III and WMS-III indexes and had larger GAI-memory discrepancy scores. Clinical outcome analyses revealed that GAI-memory scores were useful at identifying memory impairment in patients with DAT versus matched healthy participants. However, GAI-memory discrepancy scores failed to provide unique interpretive information beyond that which is gained from the memory indexes alone. Implications and future research directions are discussed.

Traumatic injuries frequently lead to infection, organ failure, and death. Health care providers rely on several injury scoring systems to quantify the extent of injury and to help predict clinical outcome. Physiological, anatomical, and clinical laboratory analytic scoring systems (Acute Physiology and Chronic Health Evaluation [APACHE], Injury Severity Score [ISS]) are utilized, with limited success, to predict outcome following injury. The recent development of techniques for measuring the expression level of all of a person’s genes simultaneously may make it possible to develop an injury scoring system based on the degree of gene activation. We hypothesized that a peripheral blood leukocyte gene expression score could predict outcome, including multiple organ failure, following severe blunt trauma. To test such a scoring system, we measured gene expression of peripheral blood leukocytes from patients within 12 h of traumatic injury. cRNA derived from whole blood leukocytes obtained within 12 h of injury provided gene expression data for the entire genome that were used to create a composite gene expression score for each patient. Total blood leukocytes were chosen because they are active during inflammation, which is reflective of poor outcome. The gene expression score combines the activation levels of all the genes into a single number which compares the patient’s gene expression to the average gene expression in uninjured volunteers. Expression profiles from healthy volunteers were averaged to create a reference gene expression profile which was used to compute a difference from reference (DFR) score for each patient. This score described the overall genomic response of patients within the first 12 h following severe blunt trauma. Regression models were used to compare the association of the DFR, APACHE, and ISS scores with outcome. We hypothesized that patients with a total gene response more different from uninjured volunteers would tend to have poorer outcome than those more similar. Our data show that for measures of poor outcome, such as infections, organ failures, and length of hospital stay, this is correct. DFR scores were associated significantly with adverse outcome, including multiple organ failure, duration of ventilation, length of hospital stay, and infection rate. The association remained significant after adjustment for injury severity as measured by APACHE or ISS. A single score representing changes in gene expression in peripheral blood leukocytes within hours of severe blunt injury is associated with adverse clinical outcomes that develop later in the hospital course. Assessment of genome-wide gene expression provides useful clinical information that is different from that provided by currently utilized anatomic or physiologic scores. PMID:19593405

Soft neurological signs are minor, non localizing, objective abnormalities, thought to reflect damage in cortical and sub-cortical connections or connections within different cortical regions. Regional structural grey matter anomalies have already been observed and correlated with the presence of cognitive deficits and presence of soft neurological signs in schizophrenic patients. Drug naive patients presenting with first episode of psychosis (FEP)were clinically evaluated for soft neurological signs using the Cambridge Neurological Inventory. The soft neurological signs scores were compared with scores in healthy volunteers. In the patient group, this score was also correlated with demographic and disorder variables. Of the 30 patients with FEP, 60% were women. The average age of the participant was 36.2 years. The average duration of illness was 1.55 years. More than 50% of the patients had schizophrenia. 93.3% of patients with FEP had atleast one soft neurological sign compared to 16.6% of controls. The average score on BPRS was 25.86 and on PANSS was 39.29, and BPRS, PANSS scores had a significant correlation with total soft neurological signs score. There is a significantly higher incidence of soft neurological signs in patients with FEP, particularly schizophrenia. The presence of soft signs correlated with the severity of psychosis.

The Objective Structured Clinical Examination (OSCE) appears to be an effective alternative for assessing not only medical knowledge, but also clinical skills, including effective communication and physical examination skills. The purpose of the current study was to implement an OSCE model in a geriatrics fellowship program and to compare the instrument with traditional essay examination. Seventy first- and second-year geriatric fellows were initially submitted to a traditional essay examination and scored from 0 to 10 by a faculty member. The same fellows subsequently underwent an OSCE with eight 10-minute stations covering a wide range of essential aspects of geriatric knowledge. Each OSCE station had an examiner responsible for its evaluation according to a predefined checklist. Checklist items were classified for analysis purposes as clinical knowledge items (CKI) and communication skills items (CSI); fellow responses were scored from 0 to 10.Although essay examinations took from 30 to 45 minutes to complete, 180-200 minutes were required to evaluate fellows using the proposed OSCE method. Fellows scored an average of 6.2 ± 1.2 on the traditional essay examination and 6.6 ± 1.0 on the OSCE (P < .001). Subanalyses of OSCE scores indicated that average performance on CKI was lower than the average on CSI (6.4 ± 1.1 vs. 8.4 ± 1.1; P < .001). Fellow performance on the essay examination was similar to their performance on CKI (P = .13). Second-year fellows performed better than first-year fellows on the essay examination (P < .001) and CKI (P = .05), but not on CSI (P = .25).The OSCE was successfully implemented as an educational strategy during a geriatrics fellowship program. Combining different testing modalities may provide the best assessment of competence for various domains of knowledge, skills, and behavior. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

Core competencies have progressively gained importance in medical education. In other contexts, especially personnel selection and development, assessment centers (ACs) are used to assess competencies, but there is only a limited number of studies on competency-based ACs in medical education. To the best of our knowledge, the present study provides the first data on the criterion-related validity of a competency-based AC in medical education. We developed an AC tailored to measure core competencies relevant to medical education (social-ethical, communicative, self, and teaching) and tested its validity in n=30 first-year medical students using 3- to 4-year follow-up measures such as (a) objective structured clinical examinations (OSCE) on basic clinical skills (n=26), (b) OSCE on communication skills (n=21), and (c) peer feedback (n=18). The AC contained three elements: interview, group discussion, and role play. Additionally, a self-report questionnaire was provided as a basis for the interview. Baseline AC average score and teaching competency correlated moderately with the communication OSCE average score (r=0.41, p=0.03, and r=0.38, p=0.04, respectively). Social-ethical competency in the AC showed a very strong convergent association with the communication OSCE average score (r=0.60, p<0.01). The AC total score also showed a moderate correlation with the overall peer feedback score provided in Year 4 (r=0.38, p=0.06). In addition, communicative competency correlated strongly with the overall peer feedback (r=0.50, p=0.02). We found predominantly low and insignificant correlations between the AC and the OSCE on basic clinical skills (r=-0.33 to 0.30, all p's>0.05). The results showed that competency-based ACs can be used at a very early stage of medical training to successfully predict future performance in core competencies.

Collins, Shawn

2013-12-01

Current nurse anesthesia program admissions requirements usually focus on high grade point averages, Graduate Record Examination scores, number of years of acute care experience, and a personal interview to assist in predicting those who will succeed in these intensive academic and clinical programs. Some people believe these criteria may not be sufficient in predicting success and have suggested that the use of noncognitive criteria such as emotional intelligence measurements may be helpful. The purpose of this cross-sectional correlational study was to explore the relationship between emotional intelligence and academic factors of student registered nurse anesthetists at 3 points in a program--matriculation, at 1 year of study, and in the last semester of study--and the relationship of these to clinical scores and National Certification Examination scores. An ex post facto cross-sectional study design was used to gather data at 3 critical times in nurse anesthesia programs to explore the relationships between emotional intelligence scores, preadmission demographics, clinical scores, and National Certification Examination scores. The online Mayer-Salovey-Caruso Emotional Intelligence Test instrument provided 15 individual emotional intelligence scores for each subject. The statistical relationship between variables was examined.

To report pilot results for international benchmarking of learning outcomes among 426 final year medical students at the University of Queensland (UQ), Australia. Students took the International Foundations of Medicine (IFOM) Clinical Sciences Exam (CSE) developed by the National Board of Medical Examiners, USA, as a required formative assessment. IFOM CSE comprises 160 multiple-choice questions in medicine, surgery, obstetrics, paediatrics and mental health, taken over 4.5 hours. Significant implementation issues; IFOM scores and benchmarking with International Comparison Group (ICG) scores and United States Medical Licensing Exam (USMLE) Step 2 Clinical Knowledge (CK) scores; and correlation with UQ medical degree cumulative grade point average (GPA). Implementation as an online exam, under university-mandated conditions was successful. Mean IFOM score was 531.3 (maximum 779-minimum 200). The UQ cohort performed better (31% scored below 500) than the ICG (55% below 500). However 49% of the UQ cohort did not meet the USMLE Step 2 CK minimum score. Correlation between IFOM scores and UQ cumulative GPA was reasonable at 0.552 (p < 0.001). International benchmarking is feasible and provides a variety of useful benchmarking opportunities.

US Medical Student Performance on the NBME Subject Examination in Internal Medicine: Do Clerkship Sequence and Clerkship Length Matter?

Prior to graduation, US medical students are required to complete clinical clerkship rotations, most commonly in the specialty areas of family medicine, internal medicine, obstetrics and gynecology (ob/gyn), pediatrics, psychiatry, and surgery. Within a school, the sequence in which students complete these clerkships varies. In addition, the length of these rotations varies, both within a school for different clerkships and between schools for the same clerkship. The present study investigated the effects of clerkship sequence and length on performance on the National Board of Medical Examiner's subject examination in internal medicine. The study sample included 16,091 students from 67 US Liaison Committee on Medical Education (LCME)-accredited medical schools who graduated in 2012 or 2013. Student-level measures included first-attempt internal medicine subject examination scores, first-attempt USMLE Step 1 scores, and five dichotomous variables capturing whether or not students completed rotations in family medicine, ob/gyn, pediatrics, psychiatry, and surgery prior to taking the internal medicine rotation. School-level measures included clerkship length and average Step 1 score. Multilevel models with students nested in schools were estimated with internal medicine subject examination scores as the dependent measure. Step 1 scores and the five dichotomous variables were treated as student-level predictors. Internal medicine clerkship length and average Step 1 score were used to predict school-to-school variation in average internal medicine subject examination scores. Completion of rotations in surgery, pediatrics and family medicine prior to taking the internal medicine examination significantly improved scores, with the largest benefit observed for surgery (coefficient = 1.58 points; p value < 0.01); completion of rotations in ob/gyn and psychiatry were unrelated to internal medicine subject examination performance. At the school level, longer internal medicine clerkships were associated with higher scores on the internal medicine examination (coefficient = 0.23 points/week; p value < 0.01). The order in which students complete clinical clerkships and the length of the internal medicine clerkship are associated with their internal medicine subject examination scores. Findings may have implications for curriculum re-design.

To evaluate adequacy and adherence to American Society for Reproductive Medicine (ASRM) guidelines of internet information provided by Society for Assisted Reproductive Technology (SART)-affiliated clinics regarding social oocyte cryopreservation (SOC). Systematic evaluation of websites of all SART member fertility clinics. The internet. None. All websites offering SOC services were scored using a 0-13 scale, based on 10 questions designed to assess website quality and adherence to the ASRM/SART guidelines. The websites were analyzed independently by two authors. Whenever disagreement occurred, a third investigator determined the score. Scores defined website quality as excellent, ≥9; moderate, 5-8; or poor, ≤4 points. Of the 387 clinics registered as SART members, 200 offered oocyte cryopreservation services for either medical or social reasons; 147 of these advertised SOC. The average website scores of those clinics offering SOC was 3.4 ± 2.1 (range, 2-11) points. There was no significant difference in scores between private versus academic clinics or clinics performing more or less than 500 cycles per year. The majority of the websites do not follow the SART/ASRM guidelines for SOC, indicating that there is a need to improve the type and quality of information provided on SOC by SART member websites.

Teaching interprofessional (IP) teamwork skills is a goal of interprofessional education. The purpose of this study was to examine the relationship between IP teamwork skills, attitudes and clinical outcomes in a simulated clinical setting. One hundred-twenty health professions students (medicine, pharmacy, physician assistant) worked in interprofessional teams to manage a "patient" in a health care simulation setting. Students completed the Interdisciplinary Education Perception Scale (IEPS) attitudinal survey instrument. Students' responses were averaged by team to create an IEPS attitudes score. Teamwork skills for each team were rated by trained observers using a checklist to calculate a teamwork score (TWS). Clinical outcome scores (COS) were determined by summation of completed clinical tasks performed by the team based on an expert developed checklist. Regression analyses were conducted to determine the relationship of IEPS and TWS with COS. IEPS score was not a significant predictor of COS (p=0.054), but TWS was a significant predictor (p<0.001) of COS. Results suggest that in a simulated clinical setting, students' interprofessional teamwork skills are significant predictors of positive clinical outcomes. Interprofessional curricular models that produce effective teamwork skills can improve student performance in clinical environments and likely improve teamwork practice to positively affect patient care outcomes.

The aim of this study was to investigate the potential clinical benefit of tibiotalocalcaneal arthrodesis (TTCA) with an intramedullary nail with a valgus curve, two compression options, and angle-stable locking. Patients who had undergone TTCA at two tertiary hospitals were eligible. Patients who had undergone TTCA before the beginning of the study were evaluated retrospectively, then all following patients were examined prospectively. There were 59 TTCAs; 55 patients were available for analysis. Twenty-eight were evaluated retrospectively, 27 prospectively. Main Outcome Measures were an SF-36, Mazur-, and AOFAS ankle-hindfoot rating scores and radiographic examination. Bony union was obtained in 53 patients. Fifty-one patients were satisfied with the outcome. Fifty-one patients had marked subjective improvement in mobility. The mean AOFAS score of the 55 patients at the latest followup was 66.8 (range, 38 to 86). The mean Mazzur score was 68.0 (range, 30 to 83). In the prospective group, the scores were significantly improved: AOFAS score by an average of 39.6 points (p<0.001); Mazur score by an average of 43 points (p<0.001); SF-36 physical component summary score (p<0.001) and mental component summary score also improved (p<0.048). Radiology showed good hindfoot alignment. The complication rate was 25%. Compared with the literature, the data obtained in this study show a good outcome and a high rate of bony union, with comparable complication rates. Patient satisfaction was good. However, the patients still had limitations. The clinical benefit of the nail used was confirmed.

Although a ball and socket ankle deformity is usually congenital and asymptomatic, abnormal inversion and eversion mobility can result in recurrent ankle sprain and osteoarthritis. This retrospective study was performed to evaluate the clinical and radiologic outcomes of ankle fusion combined with calcaneal sliding osteotomy for severe arthritic ball and socket ankle deformity. Fourteen patients with severe arthritic ball and socket ankle deformity were followed for more than 3 years after operation. The clinical evaluation consisted of American Orthopaedic Foot & Ankle Society (AOFAS) score, Foot and Ankle Ability Measure (FAAM), visual analog scale (VAS) for pain, and subjective satisfaction score. The period to fusion and union of osteotomy, the change of hindfoot alignment angle, and complications were evaluated radiologically. AOFAS and FAAM scores were significantly improved from an average of 37.4 and 34.5 points to 74.6 and 78.5 points, respectively. VAS for pain with walking over 20 minutes was significantly improved from an average of 8.4 points to 1.9 points. The average satisfaction score of patients was 88.9 points. The difference in heel alignment angle (compared to contralateral side) was significantly improved from an average of 34.8 to 5.4 degrees. There were 2 cases of progressive arthritis in an adjacent joint and 1 case of failed fusion. Ankle fusion combined with calcaneal sliding osteotomy can be an effective operative option for ball and socket ankle deformity with advanced arthritis. In spite of increased complication rate, reliable pain relief, and restoration of gait ability through correcting hindfoot malalignment could improve the quality of life.

The aim of this study was to evaluate the clinical outcomes of three different Class II treatment modalities followed by fixed orthodontic therapy, using the American Board of Orthodontics Model Grading System (ABO-MGS). As a retrospective study, files of patients treated at postgraduate orthodontic  clinics in different cities in Turkey was randomly selected. From 1684 posttreatment records, 669 patients were divided into three groups: 269 patients treated with extraction of two upper premolars, 198 patients treated with cervical headgear, and 202 patients treated with functional appliances. All the cases were evaluated by one researcher using ABO-MGS. The χ (2), Z test, and multivariate analysis of variance were used for statistical evaluation (p < 0.05). No significant differences were found among the groups in buccolingual inclination, overjet, occlusal relationship, and root angulation. However, there were significant differences in alignment, marginal ridge height, occlusal contact, interproximal contact measurements, and overall MGS average scores. The mean treatment time between the extraction and functional appliance groups was significantly different (p = 0.017). According to total ABO-MGS scores, headgear treatment had better results than functional appliances. The headgear group had better tooth alignment than the extraction group. Headgear treatment resulted in better occlusal contacts than the functional appliances and had lower average scores for interproximal contact measurements. Functional appliances had the worst average scores for marginal ridge height. Finally, the functional appliance group had the longest treatment times.

The 360 Degree Evaluation Model is one means to provide a comprehensive view of clinical competency and readiness for progression in an online nursing program. This pilot project aimed to evaluate the effectiveness of implementing a 360 Degree Evaluation of clinical competency of graduate advanced practice nursing students. The 360 Degree Evaluation, adapted from corporate industry, encompasses assessment of student knowledge, skills, behaviors and attitudes and validates student's progression from novice to competent. Cohort of advanced practice nursing students in four progressive clinical semesters. Graduate advanced practice nursing students (N = 54). Descriptive statistics and Jonckheere's Trend Test were used to evaluate OSCE's scores from graded rubric, standardized patient survey scores, student reflection and preceptor evaluation. We identified all students passed the four OSCEs during a first attempt or second attempt. Scaffolding OSCE's over time allowed faculty to identify cohort weakness and create subsequent learning opportunities. Standardized patients' evaluation of the students' performance in the domains of knowledge, skills and attitudes, showed high scores of 96% in all OSCEs. Students' self-reflection comments were a mix of strengths and weaknesses in their self-evaluation, demonstrating themes as students progressed. Preceptor evaluation scores revealed the largest increase in knowledge and learning skills (NONPF domain 1), from an aggregate average of 90% in the first clinical course, to an average of 95%. The 360 Degree Evaluation Model provided a comprehensive evaluation of the student and critical information for the faculty ensuring individual student and cohort data and ability to analyze cohort themes.

(i) To determine whether a central tendency, median, based on patients' self-rated pain is a clinically applicable daily measure to show patients' postoperative pain on the first day after major surgery (ii) and to determine the number of self-ratings required for the calculation of this measure. Perioperative pain traits in medical records are difficult to overview. The clinical applicability of a daily documented summarising measure of patients' self-rated pain scores is little explored. A repeated measure design was carried out at three Swedish country hospitals. Associations between the measures were analysed with nonparametric statistical methods; systematic and individual group changes were analysed separately. Measure I: pain scores at rest and activity postoperative day 1; measure II: retrospective average pain from postoperative day 1. The sample consisted of 190 general surgery patients and 289 orthopaedic surgery patients with a mean age of 65; 56% were men. Forty-four percent had a pre-operative daily intake of analgesia, and 77% used postoperative opioids. A range of 4-9 pain scores seem to be eligible for the calculation of the daily measures of pain. Rank correlations for individual median scores, based on four ratings, vs. retrospective self-rated average pain, were moderate and strengthened with increased numbers of ratings. A systematic group change towards a higher level of reported retrospective pain was significant. The median values were clinically applicable daily measures. The risk of obtaining a higher value than was recalled by patients seemed to be low. Applicability increased with increased frequency of self-rated pain scores and with high-quality pain assessments. The documenting of daily median pain scores at rest and during activity could constitute the basis for obtaining patients' experiences by showing their pain severity trajectories. The measures could also be an important key to predicting postoperative health-related consequences. © 2017 John Wiley & Sons Ltd.

Study Objectives: Manual scoring of polysomnograms is a time-consuming and tedious process. To expedite the scoring of polysomnograms, several computerized algorithms for automated scoring have been developed. The overarching goal of this study was to determine the validity of the Somnolyzer system, an automated system for scoring polysomnograms. Design: The analysis sample comprised of 97 sleep studies. Each polysomnogram was manually scored by certified technologists from four sleep laboratories and concurrently subjected to automated scoring by the Somnolyzer system. Agreement between manual and automated scoring was examined. Sleep staging and scoring of disordered breathing events was conducted using the 2007 American Academy of Sleep Medicine criteria. Setting: Clinical sleep laboratories. Measurements and Results: A high degree of agreement was noted between manual and automated scoring of the apnea-hypopnea index (AHI). The average correlation between the manually scored AHI across the four clinical sites was 0.92 (95% confidence interval: 0.90–0.93). Similarly, the average correlation between the manual and Somnolyzer-scored AHI values was 0.93 (95% confidence interval: 0.91–0.96). Thus, interscorer correlation between the manually scored results was no different than that derived from manual and automated scoring. Substantial concordance in the arousal index, total sleep time, and sleep efficiency between manual and automated scoring was also observed. In contrast, differences were noted between manually and automated scored percentages of sleep stages N1, N2, and N3. Conclusion: Automated analysis of polysomnograms using the Somnolyzer system provides results that are comparable to manual scoring for commonly used metrics in sleep medicine. Although differences exist between manual versus automated scoring for specific sleep stages, the level of agreement between manual and automated scoring is not significantly different than that between any two human scorers. In light of the burden associated with manual scoring, automated scoring platforms provide a viable complement of tools in the diagnostic armamentarium of sleep medicine.

Chronic non-cancer pain is a common problem that is often accompanied by psychiatric comorbidity and disability. The effectiveness of a multi-disciplinary pain management program was tested in a 3 month before and after trial. Providers in an academic general medicine clinic referred patients with chronic non-cancer pain for participation in a program that combined the skills of internists, clinical pharmacists, and a psychiatrist. Patients were either receiving opioids or being considered for opioid therapy. The intervention consisted of structured clinical assessments, monthly follow-up, pain contracts, medication titration, and psychiatric consultation. Pain, mood, and function were assessed at baseline and 3 months using the Brief Pain Inventory (BPI), the Center for Epidemiological Studies-Depression Scale scale (CESD) and the Pain Disability Index (PDI). Patients were monitored for substance misuse. Eighty-five patients were enrolled. Mean age was 51 years, 60% were male, 78% were Caucasian, and 93% were receiving opioids. Baseline average pain was 6.5 on an 11 point scale. The average CESD score was 24.0, and the mean PDI score was 47.0. Sixty-three patients (73%) completed 3 month follow-up. Fifteen withdrew from the program after identification of substance misuse. Among those completing 3 month follow-up, the average pain score improved to 5.5 (p = 0.003). The mean PDI score improved to 39.3 (p < 0.001). Mean CESD score was reduced to 18.0 (p < 0.001), and the proportion of depressed patients fell from 79% to 54% (p = 0.003). Substance misuse was identified in 27 patients (32%). A primary care disease management program improved pain, depression, and disability scores over three months in a cohort of opioid-treated patients with chronic non-cancer pain. Substance misuse and depression were common, and many patients who had substance misuse identified left the program when they were no longer prescribed opioids. Effective care of patients with chronic pain should include rigorous assessment and treatment of these comorbid disorders and intensive efforts to insure follow up.

Methods Providers in an academic general medicine clinic referred patients with chronic non-cancer pain for participation in a program that combined the skills of internists, clinical pharmacists, and a psychiatrist. Patients were either receiving opioids or being considered for opioid therapy. The intervention consisted of structured clinical assessments, monthly follow-up, pain contracts, medication titration, and psychiatric consultation. Pain, mood, and function were assessed at baseline and 3 months using the Brief Pain Inventory (BPI), the Center for Epidemiological Studies-Depression Scale scale (CESD) and the Pain Disability Index (PDI). Patients were monitored for substance misuse. Results Eighty-five patients were enrolled. Mean age was 51 years, 60% were male, 78% were Caucasian, and 93% were receiving opioids. Baseline average pain was 6.5 on an 11 point scale. The average CESD score was 24.0, and the mean PDI score was 47.0. Sixty-three patients (73%) completed 3 month follow-up. Fifteen withdrew from the program after identification of substance misuse. Among those completing 3 month follow-up, the average pain score improved to 5.5 (p = 0.003). The mean PDI score improved to 39.3 (p < 0.001). Mean CESD score was reduced to 18.0 (p < 0.001), and the proportion of depressed patients fell from 79% to 54% (p = 0.003). Substance misuse was identified in 27 patients (32%). Conclusions A primary care disease management program improved pain, depression, and disability scores over three months in a cohort of opioid-treated patients with chronic non-cancer pain. Substance misuse and depression were common, and many patients who had substance misuse identified left the program when they were no longer prescribed opioids. Effective care of patients with chronic pain should include rigorous assessment and treatment of these comorbid disorders and intensive efforts to insure follow up. PMID:15649331

Our ongoing efforts to demonstrate effectiveness of care examined the quality of life (QoL) and patient satisfaction of chiropractic patients presenting for care in a PBRN. In addition to socio-demographic and clinical care information, we examined visit-specific satisfaction and QoL using the RAND VSQ and PROMIS-29, respectively. Our study population was comprised of 126 subjects (average age = 39.68; 97 females). The majority of respondents presented with musculoskeletal complaints with an average mean duration of 7.188 years. The mean PROMIS-25 mean T Scores were: depression (47.80); pain interference (53.49); fatigue (51.02); physical function (49.02); satisfaction with social role (52.10); anxiety (50.14); and sleep disturbance (49.88). The VSQ9 mean score was 93.4% indicating high satisfaction. Adults attending care in a chiropractic PBRN were able to successfully complete the PROMIS29 and VSQ9 instruments. Future longitudinal studies should quantify the minimal clinically important difference in mean T score changes. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to report clinical and radiological results of reverse shoulder arthroplasty (RSA) after failure of either a deltoid and/or a latissimus dorsi transfer. Between 2001 and 2011, ten patients (average age, 61 years) underwent primary RSA after a failed tendon transfer for irreparable postero-superior rotator cuff tear (five deltoid muscle transfers, four latissimus dorsi transfers and one both). Average follow-up was 48 months. Outcome measures included pain, range of motion and postoperative Constant-Murley score. Pain score improved significantly from a mean 8.3 to a mean 0.3. Mean shoulder elevation improved from 66 to 134°, and absolute Constant-Murley scores increased from 25.8 to 62.8 The mean improvement in external rotation was limited to 7.5°. Subjectively, six patients rated the result as much better and three rated it as better than before surgery. Failure of the tendon transfer with deterioration of the functional outcomes can be salvaged with a RSA with no impact on the expected outcome.

Autogenous osteochondral mosaicplasty is the most common cartilage restoration technique in standard clinical practice. The purpose of this study was to evaluate the return to sports 9 years after mosaicplasty of the femoral condyles. The long-term results of an osteochondral autograft show that patients can regain their pre-injury activity level. This study is based on a series of 25 patients with a mean age of 28.9 years (range, 16-44 years) who had stage 3 or 4 chondral lesions of the femoral condyles (according to the ICRS or ICRS-OCD scores). The origin of the lesion was osteochondritis dissecans (13 knees), osteochondral fracture sequelae (ten knees), or aseptic osteonecrosis (two knees). The average size of the lesion was 2.11 ± 0.9 cm(2). Ten patients (40%) had an associated procedure during the osteochondral autograft. The patients were assessed clinically (IKDC and Lysholm-Tegner scores) and radiographically by a reviewer independent of the team of operators. All patients were re-examined at a mean follow-up of 9 years (range, 6-15 years), with 84% satisfied or very satisfied with the procedure. The average IKDC was 74.5 ± 18.5 points. The average Lysholm score was 87.3 ± 11.6 points. The average Tegner score ranged from 6.35 ± 1.53 points prior to surgery to 5.60 ± 1.64 points after surgery (P = 0.001). The average loss was 0.64 points for patients whose presurgery Tegner score was greater than or equal to 7 (P = 0.019) and 0.3 points if lower than 7. The radiologic evaluation of 21 patients showed complete osteointegration of the grafts in 90% of cases. The results of the femoral condyle mosaic autografts are satisfactory, a mean of 9 years after surgery. The most active patients lowered their activity level while the more sedentary did not have to adapt their lifestyle. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

2012-01-01

A method for the automatic resolution of coreference between medical concepts in clinical records. A multiple pass sieve approach utilizing support vector machines (SVMs) at each pass was used to resolve coreference. Information such as lexical similarity, recency of a concept mention, synonymy based on Wikipedia redirects, and local lexical context were used to inform the method. Results were evaluated using an unweighted average of MUC, CEAF, and B(3) coreference evaluation metrics. The datasets used in these research experiments were made available through the 2011 i2b2/VA Shared Task on Coreference. The method achieved an average F score of 0.821 on the ODIE dataset, with a precision of 0.802 and a recall of 0.845. These results compare favorably to the best-performing system with a reported F score of 0.827 on the dataset and the median system F score of 0.800 among the eight teams that participated in the 2011 i2b2/VA Shared Task on Coreference. On the i2b2 dataset, the method achieved an average F score of 0.906, with a precision of 0.895 and a recall of 0.918 compared to the best F score of 0.915 and the median of 0.859 among the 16 participating teams. Post hoc analysis revealed significant performance degradation on pathology reports. The pathology reports were characterized by complex synonymy and very few patient mentions. The use of several simple lexical matching methods had the most impact on achieving competitive performance on the task of coreference resolution. Moreover, the ability to detect patients in electronic medical records helped to improve coreference resolution more than other linguistic analysis.

Objective The purpose of this study was to explore the midterm clinical outcomes of unicompartmental knee replacement (UKR) for medial knee arthropathy through a minimally invasive approach (MIA). Methods From January 2006 to June 2010, 442 consecutive patients (485 knees) were included in the study. All patients underwent MIA-UKR with the mobile bearing Oxford phrase III prosthesis. The incision was made starting 1 cm medial to the medial pole of the patella and extending distally to the tibial tubercle. Radiographic evaluations include femorotibial angle (FTA) from coronal x-rays and rectified varus deformity angle, while clinical evaluations included Knee Society Score (KSS, clinical score and function score), the Western Ontario and McMaster Universities Arthritis Index (WOMAC) osteoarthritis index and visual analog scale (VAS) for pain. Patients followed-up at 1, 3, 6, 12 months after surgery and each year thereafter. Results Four hundreds and two patients completed the entire follow-up, 40 patients (45 knees) were lost to follow-up. The average follow-up time was 73.0 ± 1.9 months. The mean length of the incisions was 5.0 ± 0.2 cm. The average FTA decreased from 183.6° ± 5.1° preoperatively to 174.3° ± 4.2° postoperatively, and the mean rectified varus deformity angle was 9.3° ± 1.2°. The KSS clinical score improved from 42.4 ± 2.9 to 92.9 ± 3.8, and the function score improved from 53.5 ± 3.8 to 93.5 ± 4.0. The WOMAC score improved from 47.5 ± 3.1 preoperatively to 12.3 ± 1.5 at the last evaluation. The VAS dropped from 7.8 ± 1.9 preoperatively to 1.6 ± 0.2 postoperatively. All clinical evaluations (KSS, WOMAC, VAS) were significantly different (p < 0.05) from pre and post-operative evaluations. The survival rate was 99.1% at 73 months, and the revision rate was 0.9%. Conclusion The midterm clinical outcomes of MIA-UKR are satisfactory in a Chinese patient population, which is a good surgical option for patients with medial arthropathy of the knee. However, longer-term follow-up studies should be performed in these patients. PMID:28472068

BACKGROUND: Neurocognitive impairment occurs in children and adults with sickle cell anemia, but little is known about neurodevelopment in very young children. We examined the neurodevelopmental status of infants participating in the Pediatric Hydroxyurea Phase III Clinical Trial (Baby Hug) to determine relationships with age, cerebral blood flow velocity, and hemoglobin concentration. METHODS: Standardized measures of infant neurodevelopment were administered to 193 infants with hemoglobin SS or hemoglobin S-β0 thalassemia between 7 and 18 months of age at the time of their baseline evaluation. Associations between neurodevelopmental scores and age, family income, parent education, hemoglobin concentration, and transcranial Doppler velocity were examined. RESULTS: Mean functioning on the baseline neurodevelopment scales was in the average range. There were no mental development scores <70 (impaired); 22 children had scores in the clinically significant range, 11 with impaired psychomotor scores and 11 with problematic behavior rating scores. Significantly poorer performance was observed with older age at baseline. Behavior rating scores were an average of 2.82 percentile points lower per month of age, with similar patterns observed with parent report using adaptive behavior scales. Parent-reported functional abilities and hemoglobin were negatively associated with higher transcranial Doppler velocities. CONCLUSIONS: Whereas overall functioning was in the normal range, behavioral and adaptive function was poorer with older age, even in this very young group of children. Explanatory mechanisms for this association between poorer developmental function and older age need to be identified. PMID:23296434

Little recent published evidence explores the relationship between academic performance in medical school and performance as a junior doctor. Although many forms of assessment are used to demonstrate a medical student's knowledge or competence, these measures may not reliably predict performance in clinical practice following graduation. This descriptive cohort study explores the relationship between academic performance of medical students and workplace performance as junior doctors, including the influence of age, gender, ethnicity, clinical attachment, assessment type and summary score measures (grade point average) on performance in the workplace as measured by the Junior Doctor Assessment Tool. There were two hundred participants. There were significant correlations between performance as a Junior Doctor (combined overall score) and the grade point average (r = 0.229, P = 0.002), the score from the Year 6 Emergency Medicine attachment (r = 0.361, P < 0.001) and the Written Examination in Year 6 (r = 0.178, P = 0.014). There was no significant effect of any individual method of assessment in medical school, gender or ethnicity on the overall combined score of performance of the junior doctor. Performance on integrated assessments from medical school is correlated to performance as a practicing physician as measured by the Junior Doctor Assessment Tool. These findings support the value of combining undergraduate assessment scores to assess competence and predict future performance.

Integrating health profile with survival for quality of life assessment.

PubMed

Hwang, Jing-Shiang; Wang, Jung-Der

2004-02-01

In cohort studies or clinical trials, measurements of quality of life (QoL) were averaged across available individuals for each group at given points in time to produce single measures for comparisons. However, estimates of these single measures may be severely biased if substantial mortality occurs over time. The objective of this study is to develop a method that integrates QoL measurement and survival for long-term evaluation of health services. We defined a mean QoL score function over time for an index population as the average QoL score of all individuals both alive and dead at each time point in the population. While a living subject's QoL can be assessed by asking one's subjective preference, the score of a decedent can be assigned a fixed value depending on the specific facet on health profile. The mean QoL score function over time is reduced to a single measure of expected cumulative QoL score, which is the area under the curve of mean QoL score function over a given time interval and can be estimated by taking a random sample from a cross-sectional survey. For the QoL score function to be extrapolated to life-long, it requires the assumption that the disease causes premature death or a long-term moderate impairment of QoL. We provided methods and computer programs for estimating mean QoL score functions and the reduced single measures for use in comparisons. A cohort of 779 breast cancer patients from Chiangmai, Thailand were followed for 12 years to demonstrate the proposed methods. The data included the 12-year complete survival records and QoL scores on 233 patients collected from a cross-sectional survey using WHOQOL questionnaire and standard gamble method. The expected cumulative QoL scores using utility and psychometric scales were compared among patients in four groups of clinical stages in this cohort for time from onset up to 12 years and life-long. We conclude that such an integration of QoL measurement with survival can be useful for the evaluation of health service and clinical decision.

To assess the clinical results of using mesh plate in management of displaced comminuted fracture patella. Between January 2014 and October 2015, nine patients with closed displaced comminuted fracture patella were fixed using mesh plate and 2mm mini screws. All fractures united after an average of 10 weeks. At final follow-up of an average 19.6 months, average postoperative Lysholm score was 89.1±4.9, and average Postoperative Böstman scale was 27.2±3.1. No hardware related complications were recorded. Low profile mesh plate is a good option in management of comminuted fracture patella with good clinical outcome. This new surgical technique may be particularly useful in comminuted fractures when patellectomy would otherwise be considered. Copyright © 2017 Elsevier Ltd. All rights reserved.

Pedersen, Ken Steen; Stege, Helle; Nielsen, Jens Peter

2011-07-01

Microwave drying as a procedure for determination of faecal dry matter in weaned pigs was evaluated and clinical relevant cut-off values between faecal consistency scores were determined. Repeatability and reproducibility were evaluated. Overall coefficient of variation was 0.03. The 95% confidence limits for any future faecal subsample examined by any operator in any replica were ± 0.85% faecal dry matter. Robustness in relation to weight of wet faeces was evaluated. The weight categories were 0.5, 1.0, 1.5, 2.0 and 3.0 g. Samples of 0.5 g gave significantly different mean faecal dry matter content compared to weighing of 1.0-3.0 g. Agreement with freeze-drying was evaluated. Lin's concordance correlation coefficient was 0.94. On average the faecal dry matter values was 1.7% (SD=1.99%) higher in freeze dried compared to micro waved samples. Non-parametric ROC analyses were used to determine optimal faecal dry matter cut-off values for clinical faecal consistency scores. The 4 consistency scores were score 1=firm and shaped, score 2=soft and shaped, score 3=loose and score 4=watery. The cut-off values were score 1: faecal dry matter content >19.5%, score 2: faecal dry matter content ≤ 19.5% and >18.0%, score 3: faecal dry matter content ≤ 18.0% and >11.3%, score 4: faecal dry matter content ≤ 11.3%. In conclusion, the microwave procedure has an acceptable repeatability/reproducibility and good agreement with freeze drying can be expected. A minimum of 1.0 g of wet faeces must be used for analyses. Faecal dry matter cut-off values between 4 different clinical consistency scores were determined. © 2011 Elsevier B.V.

Evaluation of the severity of clinical signs of cats with allergic skin diseases has used two scoring systems: Scoring Feline Allergic Dermatitis (SCORFAD) and the Feline Extent and Severity Index (FeDESI). The integrity of the cutaneous barrier can also be evaluated by measuring skin hydration. A correlation between the clinical score and skin hydration has been observed in humans and dogs with atopic dermatitis (AD). To demonstrate a correlation between the clinical score and skin hydration of cats affected with presumed AD. European short hair cats (n = 18): 11 females and seven males with a confirmed diagnosis of AD. SCORFAD and FeDESI scores were calculated and the measurements of skin hydration were assessed from seven body sites using corneometry. The correlation between the SCORFAD and FeDESI systems and skin hydration of each site, and the average skin hydration was calculated. There was a positive correlation between the SCORFAD score and skin hydration for the axilla, thorax and forelimb; for FeDESI and axilla and lumbar sites. There was a negative correlation between the FeDESI and skin hydration for the pinna (r = -0.47). Measurements of skin hydration could be a useful tool for the evaluation of allergic cats. There is limited evidence of any useful correlation between clinical scoring systems and measurements of hydration. The pinna may be a suitable region for the assessment of skin barrier function in normal and allergic cats. © 2017 ESVD and ACVD.

Hay fever & homeopathy: a case series evaluation.

Seasonal allergic rhinitis (hay fever) is common and can considerably reduce the quality of life of sufferers. Despite the wide everyday application and promising results with homeopathy, scientific evidence of its effectiveness for most ailments is scarce. The assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting. We performed a clinical observational study of eight patients in the treatment of hay fever symptoms over a two-year period (2012 and 2013) using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and four weeks of homeopathic treatment. The individualized prescription - either a single remedy or multiple remedies - was based on the totality of each patient's symptoms. The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and four weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; P<0.001) and 1.06 (SD, 0.25; P<0.001) respectively. Individualized homeopathic treatment was associated with significant alleviation of hay fever symptoms, enabling the reduction in use of conventional treatment. The results presented in this study can be considered as a step towards a pilot pragmatic study that would use more robust outcome measures and include a larger number of patients prescribed a single or a multiple homeopathic prescription on an individualized basis.

2013-03-01

Given its practicality, the internet is a primary resource for patients afflicted with diseases like peripheral neuropathy. Therefore, it is important that the readily available online resources on peripheral neuropathy are tailored to the general public, particularly concerning readability. Patient education resources were downloaded from the US National Library of Medicine, Mayo Clinic, National Institute of Neurological Disorders and Stroke, Neuropathy.org, GBS/CIDP Foundation International, Hereditary Neuropathy Foundation, Charcot-Marie-Tooth Association, Foundation for Peripheral Neuropathy, and Neuropathy Action Foundation websites. All patient education material related to peripheral neuropathy was evaluated for its level of readability using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level. The FRE scores averaged 43.4 with only the US National Library of Medicine scoring above 60 (76.5). The Flesch-Kincaid Grade Level scores averaged 11.0. All scores were above a seventh-grade level except the US National Library of Medicine, which had a score of a fifth-grade reading level. Most Americans may not fully benefit from patient education resources concerning peripheral neuropathy education on many of the websites. Only the US National Library of Medicine, which is written at a fifth-grade level, is likely to benefit the average American. © 2013 Peripheral Nerve Society.

A Study of Soft Neurological Signs and Its Correlates in Drug-Naive Patients with First Episode Psychosis

PubMed Central

Gunasekaran, Vanishree; Venkatesh, V. Mathan Kumar; Asokan, T. V.

2016-01-01

Background: Soft neurological signs are minor, non localizing, objective abnormalities, thought to reflect damage in cortical and sub-cortical connections or connections within different cortical regions. Regional structural grey matter anomalies have already been observed and correlated with the presence of cognitive deficits and presence of soft neurological signs in schizophrenic patients. Materials and Methods: Drug naive patients presenting with first episode of psychosis (FEP)were clinically evaluated for soft neurological signs using the Cambridge Neurological Inventory. The soft neurological signs scores were compared with scores in healthy volunteers. In the patient group, this score was also correlated with demographic and disorder variables. Results: Of the 30 patients with FEP, 60% were women. The average age of the participant was 36.2 years. The average duration of illness was 1.55 years. More than 50% of the patients had schizophrenia. 93.3% of patients with FEP had atleast one soft neurological sign compared to 16.6% of controls. The average score on BPRS was 25.86 and on PANSS was 39.29, and BPRS, PANSS scores had a significant correlation with total soft neurological signs score. Conclusion: There is a significantly higher incidence of soft neurological signs in patients with FEP, particularly schizophrenia. The presence of soft signs correlated with the severity of psychosis. PMID:27833222

Towards reporting standards for neuropsychological study results: A proposal to minimize communication errors with standardized qualitative descriptors for normalized test scores.

PubMed

Schoenberg, Mike R; Rum, Ruba S

2017-11-01

Rapid, clear and efficient communication of neuropsychological results is essential to benefit patient care. Errors in communication are a lead cause of medical errors; nevertheless, there remains a lack of consistency in how neuropsychological scores are communicated. A major limitation in the communication of neuropsychological results is the inconsistent use of qualitative descriptors for standardized test scores and the use of vague terminology. PubMed search from 1 Jan 2007 to 1 Aug 2016 to identify guidelines or consensus statements for the description and reporting of qualitative terms to communicate neuropsychological test scores was conducted. The review found the use of confusing and overlapping terms to describe various ranges of percentile standardized test scores. In response, we propose a simplified set of qualitative descriptors for normalized test scores (Q-Simple) as a means to reduce errors in communicating test results. The Q-Simple qualitative terms are: 'very superior', 'superior', 'high average', 'average', 'low average', 'borderline' and 'abnormal/impaired'. A case example illustrates the proposed Q-Simple qualitative classification system to communicate neuropsychological results for neurosurgical planning. The Q-Simple qualitative descriptor system is aimed as a means to improve and standardize communication of standardized neuropsychological test scores. Research are needed to further evaluate neuropsychological communication errors. Conveying the clinical implications of neuropsychological results in a manner that minimizes risk for communication errors is a quintessential component of evidence-based practice.

Evidence suggests that poor performance on standardized tests before and early in medical school is associated with poor performance on standardized tests later in medical school and beyond. This study aimed to explore relationships between standardized examination scores (before and during medical school) with test and clinical performance across all core clinical clerkships. We evaluated characteristics of 435 students at Mayo Medical School (MMS) who matriculated 2000-2009 and for whom undergraduate grade point average, medical college aptitude test (MCAT), medical school standardized tests (United States Medical Licensing Examination [USMLE] 1 and 2; National Board of Medical Examiners [NBME] subject examination), and faculty assessments were available. We assessed the correlation between scores and assessments and determined USMLE 1 cutoffs predictive of poor performance (≤10th percentile) on the NBME examinations. We also compared the mean faculty assessment scores of MMS students vs visiting students, and for the NBME, we determined the percentage of MMS students who scored at or below the tenth percentile of first-time national examinees. MCAT scores correlated robustly with USMLE 1 and 2, and USMLE 1 and 2 independently predicted NBME scores in all clerkships. USMLE 1 cutoffs corresponding to poor NBME performance ranged from 220 to 223. USMLE 1 scores were similar among MMS and visiting students. For most academic years and clerkships, NBME scores were similar for MMS students vs all first-time examinees. MCAT, USMLE 1 and 2, and subsequent clinical performance parameters were correlated with NBME scores across all core clerkships. Even more interestingly, faculty assessments correlated with NBME scores, affirming patient care as examination preparation. USMLE 1 scores identified students at risk of poor performance on NBME subject examinations, facilitating and supporting implementation of remediation before the clinical years. MMS students were representative of medical students across the nation.

2016-01-01

Purpose: Medical professionals from Korea and Laos have been working together to develop a continuing professional development training program covering the major clinical fields of primary care. This study aimed to evaluate the effectiveness of the program from 2013 to 2014 using the Kirkpatrick model. Methods: A questionnaire was used to evaluate the reaction of the trainees, and the trainers assessed the level of trainees’ performance at the beginning and the end of each clinical section. The transfer (behavioral change) of the trainees was evaluated through the review of medical records written by the trainees before and after the training program. Results: The trainees were satisfied with the training program, for which the average score was 4.48 out of 5.0. The average score of the trainees’ performance at the beginning was 2.39 out of 5.0, and rose to 3.88 at the end of each section. The average score of the medical records written before the training was 2.92 out of 5.0, and it rose to 3.34 after the training. The number of patient visits to the district hospitals increased. Conclusion: The continuing professional development training program, which was planned and implemented with the full engagement and responsibility of Lao health professionals, proved to be effective.

This study evaluated the clinical and radiographic outcomes of a series of patients treated with an anatomic inlay resurfacing implant, with a minimum two-year follow-up. Fifteen patients underwent patellofemoral-resurfacing procedures using a HemiCAP Wave Patellofemoral Inlay Resurfacing implant from 2010 to 2013. Clinical outcomes included: Visual Analog Scale (VAS), Lysholm score, Knee Society Score (KSS), and evaluation of Kujala, and Hospital for Special Surgery Patellofemoral score (HSS-PF). The postoperative complications were analyzed. Nineteen knees were evaluated; the average follow-up was 35.2months. Fourteen were women, with an average age of 54years. The pre-operative/postoperative clinical results presented a significant improvement: VAS 8/2.5, Lysholm 31.9/85.8, KSS 39.8/82.5, Kujala 32.1/79.3 and Hospital for Special Surgery Patellofemoral score (HSS-PF) 15.9/90.6. A total of 87% of patients were either satisfied or very satisfied with the overall outcome. There were no radiographic signs of loosening. Seven postoperative complications were recorded: two presented ongoing knee pain, one postoperative stiffness, one patellar bounce due to maltracking, two ilio-tibial band syndrome, and one tibial anterior tuberosity osteotomy nonunion. Two patients underwent a total knee arthroplasty conversion and were considered a failure. None of these complications were implant related. Patellofemoral inlay resurfacing for isolated patellofemoral arthritis was an effective and safe procedure with high levels of patient satisfaction. No mechanical implant failure was seen at a minimum two-year follow-up. This implant design appeared to be an alternative to the traditional patellofemoral prostheses. Concomitant osteochondral lesions, patellofemoral dysplasia or patellar maltracking might be poor prognostic factors for this type of implant. Copyright © 2017 Elsevier B.V. All rights reserved.

Purpose To evaluate the clinical and radiological results of total knee arthroplasty (TKA) using the anterior-posterior glide (APG) low contact stress (LCS) mobile-bearing system. Materials and Methods We evaluated 130 knees in 117 patients who had undergone TKA with APG LCS mobile-bearing system between September 2005 and July 2007 and could be followed over 5 years. The mean follow-up period was 68 months. The clinical and radiological results were evaluated using the American Knee Society Scoring System, Oxford knee score and the American Knee Society Roentgenographic Evaluation and Scoring System. And we analyzed short-term postoperative complications. Results The average range of motion of the knee joint was 107.9° (range, 70° to 135°) preoperatively and 125.2° (range, 90° to 135°) at the last follow-up. The average knee and functional scores were improved from 39.1 and 42.0 to 71.2 and 75.6, respectively, between the preoperative and last follow-up evaluation. The Oxford knee score was decreased from 42.9 preoperatively to 23.1 at the last follow-up. The femoro-tibial angle (anatomical axis) changed from 10.1° varus preoperatively to 3.3° valgus at the last follow-up. Radiolucency was observed in 14% of all cases. There were 1 case of traumatic dislocation of the polyethylene liner, 1 case of aseptic loosening and 6 cases of posterior instability because of posterior cruciate ligament (PCL) insufficiency. Conclusions TKA with APG LCS mobile-bearing system demonstrated relatively good short-term clinical and radiological results. However, further considerations for posterior instability associated with PCL insufficiency are needed. PMID:25229046

This expost facto correlational study sought to determine which measures of academic success in one class of BSN graduates predicted their competence as employees one year after graduation, as judged by their employers. The relationship between pre-entrance test scores, clinical experience grades, GPA, State Board Test Pool examination scores, and employer competency ratings were also determined. In keeping with the literature in fields other than nursing, the findings suggest that there may be little relationship between academic performance in a nursing program and subsequent job performance as a nurse, even though verbal ability may be predictive of success in school. While significant positive correlations were found between pre-entrance test data and final grade point averages, as well as pre-entrance test scores and State Board Test Pool examination scores, there was little evidence that pre-entrance test scores were predictive of nursing abilities. Isolated correlations were found between the clinical components of some nursing courses and specific nursing abilities. Using multiple regression analysis, no clinical course grade was found to be a significant predictor of the mean employer competency rating. Significant predictors were found for only four of the individual nursing abilities, with the clinical component of Leadership in Nursing being the most frequent and best predictor.

EEG Biofeedback (also known as neurofeedback) has been in use as a clinical intervention for well over 30 years; however, it has made very little impact on clinical care. One reason for this has been the difficulty in designing research to measure clinical change in the real world. While substantial evidence exists for its efficacy in treating attention deficit/hyperactivity disorder, relatively little evidence exists for its utility in other disorders including posttraumatic stress disorder (PTSD). The current study represents a "proof-of-concept" pilot for the use of neurofeedback with multiply-traumatized individuals with treatment-resistant PTSD. Participants completed 40 sessions of neurofeedback training two times per week with sensors randomly assigned (by the study coordinator, who was not blind to condition) to sensor placements of either T4-P4 or T3-T4. We found that neurofeedback significantly reduced PTSD symptoms (Davidson Trauma Scale scores averaged 69.14 at baseline to 49.26 at termination), and preceded gains in affect regulation (Inventory of Altered Self-Capacities-Affect Dysregulation scores averaged 23.63 at baseline to 17.20 at termination). We discuss a roadmap for future research.

Comprehension of the medical diagnoses of doctors and treatment of diseases is important to understand the underlying principle in selecting appropriate acupoints. The pattern recognition process that pertains to symptoms and diseases and informs acupuncture treatment in a clinical setting was explored. A total of 232 clinical records were collected using a Charting Language program. The relationship between symptom information and selected acupoints was trained using an artificial neural network (ANN). A total of 11 hidden nodes with the highest average precision score were selected through a tenfold cross-validation. Our ANN model could predict the selected acupoints based on symptom and disease information with an average precision score of 0.865 (precision, 0.911; recall, 0.811). This model is a useful tool for diagnostic classification or pattern recognition and for the prediction and modeling of acupuncture treatment based on clinical data obtained in a real-world setting. The relationship between symptoms and selected acupoints could be systematically characterized through knowledge discovery processes, such as pattern identification.

A significant determinant of population health outcomes is the quality of care provided for noncommunicable diseases, obstetric, and pediatric care. We present results on clinical practice quality in these areas as measured among nearly 4,000 providers working at more than 1,000 facilities in 6 Eastern European and Central Asian countries. This study was conducted between March 2011 and April 2013 in Albania, Armenia, Georgia, Kazakhstan, Kirov Province in Russia, and Tajikistan. Using a probability proportional-to-size sampling technique, based on number of hospital beds, we randomly selected within each country 42 hospitals and their associated primary health care clinics. Physicians and midwives within each clinical area of interest were randomly selected from each hospital and clinic and asked how they would care for simulated patients using Clinical Performance and Value (CPV) vignettes. Facility administrators were also asked to complete a facility survey to collect structural measures of quality. CPV vignettes were scored on a scale of 0% to 100% for each provider. We used descriptive statistics and t tests to identify significant differences in CPV scores between hospitals and clinics and rural vs. urban facilities, and ANOVA to identify significant differences in CPV scores across countries. We found that quality of care, as concurrently measured by performance on CPV vignettes, was generally poor and widely variable within and between countries. Providers in Kirov Province, Russia, had the highest overall performance, with an average score of 70.8%, while providers in Albania and Tajikistan had the lowest average score, each at 50.8%. The CPV vignettes with the lowest scores were for multiple noncommunicable disease risk factors and birth asphyxia. A considerable proportion (11%) of providers performed well on the CPV vignettes, regardless of country, facility, or structural resources available to them. Countries of Eastern Europe and Central Asia are challenged by poor performance as measured by clinical care vignettes, but there is potential for provision of high-quality care by a sizable proportion of providers. Large-scale assessments of quality of care have been hampered by the lack of effective measurement tools that provide generalizable and reliable results across diverse economic, cultural, and social settings. The feasibility of quality measurement using CPV vignettes in these 6 countries and the ability to combine results with individual feedback could significantly enhance strategies to improve quality of care, and ultimately population health. © Peabody et al.

Abstract Given the recognition that disease‐modifying therapies should focus on earlier Parkinson's disease stages, trial enrollment based purely on clinical criteria poses significant challenges. The goal herein was to determine the utility of dopamine transporter neuroimaging as an enrichment biomarker in early motor Parkinson's disease clinical trials. Patient‐level longitudinal data of 672 subjects with early‐stage Parkinson's disease in the Parkinson's Progression Markers Initiative (PPMI) observational study and the Parkinson Research Examination of CEP‐1347 Trial (PRECEPT) clinical trial were utilized in a linear mixed‐effects model analysis. The rate of worsening in the motor scores between subjects with or without a scan without evidence of dopamine transporter deficit was different both statistically and clinically. The average difference in the change from baseline of motor scores at 24 months between biomarker statuses was –3.16 (90% confidence interval [CI] = –0.96 to –5.42) points. Dopamine transporter imaging could identify subjects with a steeper worsening of the motor scores, allowing trial enrichment and 24% reduction of sample size. PMID:28749580

We report our clinical experience using the modified Cadenat method to treat acromioclavicular joint dislocation, and discuss the usefulness of this method. This study examined 6 shoulders in 6 patients (5 males, 1 female) who were diagnosed with acromioclavicular joint dislocation and treated with the modified Cadenat method at our hospital. Average age at onset was 49.3 years (26-78 years), average time interval from injury until surgery was 263.8 days (10 to 1100 days), and the average follow-up period was 21.7 months (12 to 42 months). Post-operative assessment was performed using plain radiographs to determine shoulder joint dislocation rate and Japanese Orthopaedic Association (JOA) score. The average post-operative JOA score was 94.1 points (91 to 100 points). The acromioclavicular joint dislocation rate improved from 148.7% (72 to 236%) before surgery to 28.6% (0 to 60%) after surgery. Conservative treatment has been reported to achieve good outcomes in acromioclavicular joint dislocations. However, many patients also experience chronic pain or a sensation of fatigue upon putting the extremity in an elevated posture, and therefore ensuring the stability of the acromioclavicular joint is crucial for highly active patients. In this study, we treated acromioclavicular joint dislocations by the modified Cadenat method, and were able to achieve favorable outcomes.

To evaluate the clinical outcomes of thermal pulsation treatment in patients with meibomian gland dysfunction (MGD) and dry eye secondary to Sjogren disease. Twenty-four eyes from 13 patients with previously diagnosed Sjogren disease who presented to our institution with dry eye symptoms and had thermal pulsation treatment were prospectively followed up. Patients underwent comprehensive slit-lamp examination, including MGD grading, gland oil flow, corneal and conjunctival staining scores, and tear break-up time (TBUT). Tear osmolarity was tested before and after treatment. The average patient age was 62.4 years (range, 31-78 yrs); 12 were women and 1 a man. The average meibomian gland oil flow score showed an increase from pretreatment 0.71 to 1.75 at 1 year posttreatment (range 9-15 months) (P = 0.001). The average corneal staining score decreased from a pretreatment grade of 1.04 to a posttreatment grade of 0.36 (P < 0.001). The average conjunctival staining score decreased from a pretreatment grade of 1.5 to a posttreatment grade of 0.48 (P < 0.001). The average tear break-up time improved from 3.8 seconds before treatment to 7.5 seconds after thermal pulsation treatment (P < 0.001). There was no statistically significant change in the tear osmolarity or Ocular Surface Disease Index score. Our findings suggest that MGD is an important contributor to dry eye disease in patients with Sjogren disease and should not be overlooked when considering treatment options. Thermal pulsation is a therapeutic option for patients with Sjogren disease who have MGD and dry eye symptoms. After a single treatment, patients exhibited increased oil flow and tear break-up time with an associated decrease in corneal and conjunctival staining.

A possible relationship has been suggested between social anxiety and dissociation. Traumatic experiences, especially childhood abuse, play an important role in the aetiology of dissociation. This study assesses childhood trauma history, dissociative symptoms, and dissociative disorder comorbidity in patients with social anxiety disorder (SAD). The 94 psychotropic drug-naive patients participating in the study had to meet DSM-IV criteria for SAD. Participants were assessed using the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), the Dissociation Questionnaire (DIS-Q), the Liebowitz Social Anxiety Scale (LSAS), and the Childhood Trauma Questionnaire (CTQ). Patients were divided into two groups using the DIS-Q, and the two groups were compared. The evaluation found evidence of at least one dissociative disorder in 31.91% of participating patients. The most prevalent disorders were dissociative disorder not otherwise specified (DDNOS), dissociative amnesia, and depersonalization disorders. Average scores on LSAS and fear and avoidance sub-scale averages were significantly higher among the high DIS-Q group (p < .05). In a logistic regression taking average LSAS scores as the dependent variable, the five independent variables DIS-Q, CTQ-53 total score, emotional abuse, sexual abuse, and emotional neglect were associated with average LSAS scores among patients with SAD (p < .05). It is concluded that, on detecting SAD symptoms during hospitalization, the clinician should not neglect underlying dissociative processes and traumatic experiences among these patients.

To assess the relationship between clinically assessed Upper Motor Neuron (UMN) disease in Amyotrophic Lateral Sclerosis (ALS) and local diffusion alterations measured in the brain corticospinal tract (CST) by a tractography-driven template-space region-of-interest (ROI) analysis of Diffusion Tensor Imaging (DTI). This cross-sectional study included 34 patients with ALS, on whom DTI was performed. Clinical measures were separately obtained including the Penn UMN Score, a summary metric based upon standard clinical methods. After normalizing all DTI data to a population-specific template, tractography was performed to determine a region-of-interest (ROI) outlining the CST, in which average Mean Diffusivity (MD) and Fractional Anisotropy (FA) were estimated. Linear regression analyses were used to investigate associations of DTI metrics (MD, FA) with clinical measures (Penn UMN Score, ALSFRS-R, duration-of-disease), along with age, sex, handedness, and El Escorial category as covariates. For MD, the regression model was significant (p = 0.02), and the only significant predictors were the Penn UMN Score (p = 0.005) and age (p = 0.03). The FA regression model was also significant (p = 0.02); the only significant predictor was the Penn UMN Score (p = 0.003). Measured by the template-space ROI method, both MD and FA were linearly associated with the Penn UMN Score, supporting the hypothesis that DTI alterations reflect UMN pathology as assessed by the clinical examination.

Purpose: Few medical students are given proper clinical training in oncology, much less radiation oncology. We attempted to assess the value of adding a radiation oncology clinical rotation to the medical school curriculum. Methods and Materials: In July 2010, Jefferson Medical College began to offer a 3-week radiation oncology rotation as an elective course for third-year medical students during the core surgical clerkship. During 2010 to 2012, 52 medical students chose to enroll in this rotation. The rotation included outpatient clinics, inpatient consults, didactic sessions, and case-based presentations by the students. Tests of students' knowledge of radiation oncology were administeredmore » anonymously before and after the rotation to evaluate the educational effectiveness of the rotation. Students and radiation oncology faculty were given surveys to assess feedback about the rotation. Results: The students' prerotation test scores had an average of 64% (95% confidence interval [CI], 61-66%). The postrotation test scores improved to an average of 82% (95% CI, 80-83%; 18% absolute improvement). In examination question analysis, scores improved in clinical oncology from 63% to 79%, in radiobiology from 70% to 77%, and in medical physics from 62% to 88%. Improvements in all sections but radiobiology were statistically significant. Students rated the usefulness of the rotation as 8.1 (scale 1-9; 95% CI, 7.3-9.0), their understanding of radiation oncology as a result of the rotation as 8.8 (95% CI, 8.5-9.1), and their recommendation of the rotation to a classmate as 8.2 (95% CI, 7.6-9.0). Conclusions: Integrating a radiation oncology clinical rotation into the medical school curriculum improves student knowledge of radiation oncology, including aspects of clinical oncology, radiobiology, and medical physics. The rotation is appreciated by both students and faculty.« less

Our objective was to evaluate the effectiveness of hands-on training at a bedside ultrasound (US) symposium ("Ultrafest") to improve both clinical knowledge and image acquisition skills of medical students. Primary outcome measure was improvement in multiple choice questions on pulmonary or Focused Assessment with Sonography in Trauma (FAST) US knowledge. Secondary outcome was improvement in image acquisition for either pulmonary or FAST. Prospective cohort study of 48 volunteers at "Ultrafest," a free symposium where students received five contact training hours. Students were evaluated before and after training for proficiency in either pulmonary US or FAST. Proficiency was assessed by clinical knowledge through written multiple-choice exam, and clinical skills through accuracy of image acquisition. We used paired sample t-tests with students as their own controls. Pulmonary knowledge scores increased by a mean of 10.1 points (95% CI [8.9-11.3], p<0.00005), from 8.4 to a posttest average of 18.5/21 possible points. The FAST knowledge scores increased by a mean of 7.5 points (95% CI [6.3-8.7] p<0.00005), from 8.1 to a posttest average of 15.6/21. We analyzed clinical skills data on 32 students. The mean score was 1.7 pretest and 4.7 posttest of 12 possible points. Mean improvement was 3.0 points (p<0.00005) overall, 3.3 (p=0.0001) for FAST, and 2.6 (p=0.003) for the pulmonary US exam. This study suggests that a symposium on US can improve clinical knowledge, but is limited in achieving image acquisition for pulmonary and FAST US assessments. US training external to official medical school curriculum may augment students' education.

When conservative treatment fails to provide relief for a symptomatic accessory navicular, surgical intervention may be necessary. Numerous studies have been published, reporting the results of the traditional Kidner procedure and alternative surgical techniques, all of which produce mostly satisfactory clinical outcomes. The purpose of this study was to report the clinical results, utilizing the American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Scale, of surgical management for symptomatic accessory navicular with simple excision and anatomic repair of the tibialis posterior tendon. The authors retrospectively reviewed the results of 13 consecutive patients (14 feet) who underwent surgical treatment for symptomatic accessory navicular. The patients ranged in age from 16 to 64 years (average, 34.1 years; mean, 28.2 years) at the time of surgery. All patients had a type II accessory navicular. The average follow-up of the patients involved in the study was 103.4 months (range, 45-194 months). The AOFAS Midfoot Scale was utilized to determine both preoperative and postoperative clinical status of the 14 feet included in the study. The average preoperative AOFAS score was 48.2 (range, 20-75; mean, 38.8). The average postoperative AOFAS score was 94.5 (range, 83-100; mean, 94.3). At last follow-up, 13 of 14 feet were without any pain, no patients had activity limitations, and only two of 14 feet required shoe insert modification. Postoperatively, no patients had a clinically notable change in their preoperative midfoot longitudinal arch alignment. All of the patients in the study were satisfied with the outcome of their surgery and would undergo the same operation again under similar circumstances. When conservative measures fail to relieve the symptoms of a painful accessory navicular, simple excision of the accessory navicular and anatomic repair of the posterior tibialis tendon is a successful intervention. Overall, the procedure provides reliable pain relief and patient satisfaction. In the current study, the clinical status of each patient improved significantly postoperatively, quantified utilizing the AOFAS Midfoot Scale.

Objective To compare word recognition scores for adults with hearing loss measured using earphones and in the sound field without and with hearing aids (HA) Study design Independent review of pre-surgical audiological data from an active middle ear implant (MEI) FDA clinical trial Setting Multicenter prospective FDA clinical trial Patients Ninety-four adult HA users Interventions/Main outcomes measured Pre-operative earphone, unaided and aided pure tone thresholds, word recognition scores, and speech intelligibility index. Results We performed an independent review of pre-surgical audiological data from a MEI FDA trial and compared unaided and aided word recognition scores with participants’ HAs fit according to the NAL-R algorithm. For 52 participants (55.3%), differences in scores between earphone and aided conditions were >10%; for 33 participants (35.1%), earphone scores were higher by 10% or more than aided scores. These participants had significantly higher pure tone thresholds at 250 Hz, 500 Hz, and 1000 Hz), higher pure tone averages, higher speech recognition thresholds, (and higher earphone speech levels (p=0.002). No significant correlation was observed between word recognition scores measured with earphones and with hearing aids (r=.14; p=0.16), whereas a moderately high positive correlation was observed between unaided and aided word recognition (r=0.68; p<0.001). Conclusion Results of the these analyses do not support the common clinical practice of using word recognition scores measured with earphones to predict aided word recognition or hearing aid benefit. Rather, these results provide evidence supporting the measurement of aided word recognition in patients who are considering hearing aids. PMID:27631832

Children with obstetrical brachial plexus injury often develop an internal rotation and adduction contracture about the shoulder as a secondary deformity, resulting in an inability to externally rotate and abduct the shoulder. The Hoffer procedure is evaluated for its potential benefit in improving shoulder abduction and external rotation and its impact on activities of daily living. This is a retrospective review of patients treated in brachial plexus injury clinic who underwent tendon transfer procedures about the shoulder. Preoperative and postoperative active movement and active range of motion were measured and recorded using the Mallet scale and the Active Movement Scale. Twenty patients were included in the study. Average age at time of surgery was 6.35 years. Thirteen patients had primary brachial plexus reconstructive surgery and four patients had concomitant wrist extension tendon transfer procedures. All patients had full passive range of motion preoperatively. The average follow-up period was 25.45 months. Average differences in pre-Hoffer and post-Hoffer Mallet scale scores are as follows: active abduction, 1.20; external rotation, 1.35; hand-to-neck, 1.25; hand-to-back, 0.75; hand-to-mouth, 0.65; and aggregate score, 5.20 (p<0.001 for all). Average differences in relevant pre-Hoffer and post-Hoffer Active Movement Scale scores are as follows: shoulder abduction, 2.10; shoulder external rotation, 4.25; and shoulder internal rotation, -0.80. All patients maintained full range of motion passively; thus, no functional loss was experienced. These results showed very high statistical significance (p<0.001 for all) and clinical significance. Younger patients (≤6 years) and those with better preoperative shoulder flexion and shoulder internal rotation yielded better postoperative results. The Hoffer procedure provides clinically and statistically significant improvement in external rotation and abduction while preserving functional internal rotation range in the child with obstetrical brachial plexus palsy and secondary shoulder deformity.

Radial head arthroplasty (RHA) is a popular method of treatment for complex fractures of the radial head. The purpose of this study was to investigate patient outcomes and radiographic findings associated with a single anatomic monopolar press-fit radial head system commonly used for the treatment of radial head fractures. A retrospective review of prospectively collected data was performed for a consecutive series of patients treated with a press-fit anatomically designed RHA between November 2007 and April 2014. The most recent radiographs were evaluated for loosening, stress shielding, and instability. Postoperative motion and outcomes were reported at most recent follow-up. At an average follow-up of 30 months, 6 of the 15 patients (40%) demonstrated radiographic loosening. Six of the 9 patients (67%) without loosening demonstrated stress shielding (average, 6 mm). Functional outcome scores included a mean American Shoulder and Elbow Surgeons score of 70, Mayo Elbow Performance Score of 85, visual analog scale score for pain of 2, visual analog scale score for function of 7, and Single Assessment Numeric Evaluation score of 75. Average flexion-extension arc was 14° to 138°, and average pronation-supination was 75° to 74°. All 6 of the patients with radiographic loosening had undergone RHA with an associated ligamentous injury repair. Satisfaction among patients was high as no patient reported an unsatisfactory outcome. The use of an anatomic, press-fit monopolar RHA in the management of acute complex radial head fractures has yielded excellent clinical outcomes despite high rates of radiographic loosening and stress shielding. Press-fit RHA in the setting of ligamentous injury warrants further investigation because of a high rate of implant loosening observed.

To determine if U.S. female veterans had demonstrable improvements in neck pain after chiropractic management at a Veterans Affairs (VA) hospital. This was a retrospective cross-sectional study of medical records from female veterans attending a VA chiropractic clinic for neck pain from 2009 to 2015. Paired t-tests were used to compare baseline and discharge numeric rating scale (NRS) and Neck Bournemouth Questionnaire (NBQ) scores with a minimum clinically important difference (MCID) set at a 30% change from baseline. Thirty-four veterans met the inclusion criteria and received a mean of 8.8 chiropractic treatments. For NRS, the mean score improvement was 2.7 (95%CI, 1.9-3.5, p < .001). For the NBQ, the mean score improvement was 13.7 (95%CI, 9.9-17.5, p < .001). For the MCID, the average percent improvement was 45% for the NRS and 38% for the NBQ. Female veterans with neck pain experienced a statistically and clinically significant reduction in NRS and NBQ scores. Copyright © 2017 Elsevier Ltd. All rights reserved.

Treatment of talar neck fractures is challenging. Various surgical approaches and fixation methods have been documented. Clinical outcomes are often dissatisfying due to inadequate reduction and fixation with high rates of complications. Obtaining satisfactory clinical outcomes with minimum complications remains a hard task for orthopaedic surgeons. In the period from May 2007 to September 2010, a total of 31 cases with closed displaced talar neck fractures were treated surgically in our department. Injuries were classified according to the Hawkins classification modified by Canale and Kelly. Under general anaesthesia with sufficient muscle relaxation, urgent closed reduction was initiated once the patients were admitted; if the procedure failed, open reduction and provisional stabilisation with Kirschner wires through an anteromedial approach with tibiometatarsal external fixation were performed. When the soft tissue had recovered, definitive fixation was performed with plate and screws through dual approaches. The final follow-up examination included radiological analysis, clinical evaluation and functional outcomes which were carried out according to the Ankle-Hindfoot Scale of the American Orthopaedic Foot and Ankle Society (AOFAS), patient satisfaction and SF-36. Twenty-eight patients were followed up for an average of 25 months (range 18-50 months) after the injury. Only two patients had soft tissue complications, and recovery was satisfactory with conservative treatment. All of the fractures healed anatomically without malunion and nonunion, and the average union time was 14 weeks (range 12-24 weeks). Post-traumatic arthritis developed in ten cases, while six patients suffered from avascular necrosis of the talus. Secondary procedures included three cases of subtalar arthrodesis, one case of ankle arthrodesis and one case of total ankle replacement. The mean AOFAS hindfoot score was 78 (range 65-91). According to the SF-36, the average score of the physical component summary was 68 (range 59-81), and the average score of the mental component summary was 74 (range 63-85). Talar neck fractures are associated with a high incidence of long-term disability and complications. Urgent reduction of the fracture-dislocation and delayed plate fixation through a dual approach when the soft tissue has recovered may minimise the complications and provide good clinical outcomes.

Point-of-care ultrasound has been shown to decrease the use of expensive diagnostic studies and improve quality outcome measures. Currently, there is a large desire for training in family medicine residencies, but very few programs have established curricula. We sought to develop a family medicine residency curriculum and evaluate it with tools we developed. We wanted our curriculum to be easy to adopt by other residency programs, even if they did not have many well-trained ultrasound faculty. We developed a curriculum in the form of a 4-week rotation in a family medicine residency program. It consisted of self-study videos, hands-on training, and image review. We followed residents in postgraduate years 1 to 3 over a 12-month period. We developed tools, including a knowledge exam, to test image interpretation and clinical decision making, an observed structured clinical exam to assess scanning skills, and a survey to assess perceptions of point-of-care ultrasound in family medicine. The assessments were administered before and after each resident's rotation. Seventeen residents completed the rotation. The average knowledge test score improved significantly, from 62 to 84%. The average observed structured clinical exam scores also improved significantly, from 41 to 85%. The average perception survey scores improved slightly from 4.4 to 4.6. We developed a point-of-care ultrasound curriculum for family medicine residency programs that improves measures of resident attitude, skills, and knowledge. This curriculum can be adopted by residency programs with few faculty members who are experienced in ultrasound. © 2017 by the American Institute of Ultrasound in Medicine.

To study the clinical effects of Achillon for the treatment of acute Achilles tendon rupture (AATR). From April 2009 to April 2010, 19 patients with AATR who were treated with Achillon were retrospectively analyzed. There were 17 males and 2 females, with an average age of 40.2 years (30 to 58 years). There were 9 cases of sports injury, and 2 case of fall injury. The time from injury to surgery ranged from 0 to 8 days (2.2 days on average). The results of Thompson test and single heel rise test were positive in 19 cases. Clinical data were assessed with the patient satisfaction and the AOFAS hindfoot score during follow-up. All the patients were followed up, and the duration ranged from 12 to 28 months (19.9 months on average). The average operation time was 41 minutes. There were no wound infections, recurrent rupture, or sural nerve complications. At the latest follow-up, 18 patients were totally satisfied with the surgical result, 1 patient feel generally due to mild pain when running. None of the patients were dissatisfied with the final results the latest follow-up. At the latest follow-up, the AOFAS score was 98.42 +/- 3.29 (89 to 100). All the patients regained normal range of motion and were able to resume their previous activities at six months after operation, with a high rate of satisfaction. Average decreased of mid-calf circumference was (0.82 +/- 0.85) cm (ranged from 0 to 3 cm). Treatment with Achillon is safe, effective for AATR with low incidence of complications and early active rehabilitation can be carried out. It is a good method to treat AATR.

Septal deviations might cause nasal obstruction and negative impact on the quality of life of individuals. The efficacy of septoplasty for treatment of septal deviation and the predictors of satisfactory surgical outcomes remain controversial. Technical variability, heterogeneity of research samples and absence of a solid tool for clinical evaluation are the main hindrances to the establishment of reliable statistical data regarding the procedure. To evaluate the clinical improvements in the disease-specific quality-of-life between patients submitted to septoplasty with bilateral outfracture of the inferior turbinate under sedation and local anesthesia in a tertiary hospital and to assess possible clinical-epidemiological variables associated with functional outcome. Fifty-two patients consecutively submitted to septoplasty with bilateral outfracture of the inferior turbinate for treatment of nasal obstruction filled in forms regarding clinical and epidemiological information during enrollment and had their symptom objectively quantified using the Nose Obstruction Symptom Evaluation (NOSE) scale preoperatively and one and three months after the procedure. Statistical analysis aimed to determine overall and stratified surgical outcomes and to investigate correlations between the clinical-epidemiological variables with the scores obtained. Statistically significant improvement in the preoperative NOSE questionnaire compared to the scores obtained three months after surgery was demonstrated (p<0.001, T-Wilcoxon), with strong correlation between the preoperative score and the postoperative improvement during this period (r=-0.614, p<0.001, Spearman). After one month, patients reached in average 87.15% of the result obtained at the study termination. Smokers and patients with rhinitis and/or pulmonary comorbidity showed increased average preoperative NOSE scores, although without statistical significance (p>0.05). Gender, age, history of rhinitis and presence of pulmonary comorbidity did not influence significantly surgical outcomes (p>0.05). Smokers presented greater reduction in NOSE scores during the study (p=0.043, U-Mann-Whitney). Septoplasty with bilateral outfracture of the inferior turbinate has proven to significantly improve disease-specific quality-of-life and this favorable outcome seems to occur precociously.

Background The aim of the present study was to make a preoperative and postoperative clinical and functional evaluation of patients who underwent transanal repair of rectocele and rectal mucosectomy with a single circular stapler (TRREMS procedure) as treatment for obstructed defecation syndrome (ODS) caused by rectocele and rectal mucosal prolapse (RMP). Methods This prospective study included 35 female patients, 34 multiparous and one nulliparous, with an average age of 47.5 years (range 31–67 years), rectocele grade II (n = 13/37.1%) or grade III (n = 22/62.9%), associated with RMP. The study parameters included ODS, constipation, functional continence scores and pre- and postoperative cinedefecographic findings. Results The average preoperative ODS score, the constipation score and the functional continence score were significantly reduced after surgery from 10.63 to 2.91 (p = 0.001), 15.23 to 4.46 (p = 0.001) and 2.77 to 1.71 (p = 0.001), respectively. Between the first and the eighth postoperative day, the average visual analog scale pain score fell from 5.23 to 1.20 (p = 0.001). Satisfaction with treatment outcome was 79.97, 86.54, 87.65 and 88.06 at 1, 3, 6 and 12 months, respectively. Cinedefecography revealed average reductions in rectocele size from 19.23 ± 8.84 mm (3–42) to 6.68 ± 3.65 mm (range 0–7) at rest and from 34.89 ± 12.30 mm (range 20–70) to 10.94 ± 5.97 mm (range 0–25) during evacuation (both P = 0.001). Conclusion The TRREMS procedure is a safe and efficient technique associated with satisfactory anatomic and functional results and with a low incidence of postoperative pain and complications.

To determine (1) whether platelet-rich plasma (PRP) injection significantly improves validated patient-reported outcomes in patients with symptomatic knee osteoarthritis (OA) at 6 and 12 months postinjection, (2) differences in outcomes between PRP and corticosteroid injections or viscosupplementation or placebo injections at 6 and 12 months postinjection, and (3) similarities and differences in outcomes based on the PRP formulations used in the analyzed studies. PubMed, Cochrane Central Register of Controlled Trials, SCOPUS, and Sport Discus were searched for English-language, level I evidence, human in vivo studies on the treatment of symptomatic knee OA with intra-articular PRP compared with other options, with a minimum of 6 months of follow-up. A quality assessment of all articles was performed using the Modified Coleman Methodology Score (average, 83.3/100), and outcomes were analyzed using 2-proportion z-tests. Six articles (739 patients, 817 knees, 39% males, mean age of 59.9 years, with 38 weeks average follow-up) were analyzed. All studies met minimal clinical important difference criteria and showed significant improvements in statistical and clinical outcomes, including pain, physical function, and stiffness, with PRP. All but one study showed significant differences in clinical outcomes between PRP and hyaluronic acid (HA) or PRP and placebo in pain and function. Average pretreatment Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were 52.36 and 52.05 for the PRP and HA groups, respectively (P = .420). Mean post-treatment WOMAC scores for PRP were significantly better than for HA at 3 to 6 months (28.5 and 43.4, respectively; P = .0008) and at 6 to 12 months (22.8 and 38.1, respectively; P = .0062). None of the included studies used corticosteroids. In patients with symptomatic knee OA, PRP injection results in significant clinical improvements up to 12 months postinjection. Clinical outcomes and WOMAC scores are significantly better after PRP versus HA at 3 to 12 months postinjection. There is limited evidence for comparing leukocyte-rich versus leukocyte-poor PRP or PRP versus steroids in this study. Level I, systematic review of Level I studies.

Symphysis pubis pain is a significant problem for some pregnant women. The purpose of this study was to investigate the effects of exercise, advice, and pelvic support belts on the management of symphysis pubis dysfunction during pregnancy. Ninety pregnant women with symphysis pubis dysfunction were randomly assigned to 3 treatment groups. A randomized masked prospective experimental clinical trial was conducted. Specific muscle strengthening exercises and advice concerning appropriate methods for performing activities of daily living were given to the 3 groups, and 2 of the groups were given either a rigid pelvic support belt or a nonrigid pelvic support belt. The dependent variables, which were measured before and after the intervention, were a Roland-Morris Questionnaire score, a Patient-Specific Functional Scale score, and a pain score (101-point numerical rating score). After the intervention, there was a significant reduction in the Roland-Morris Questionnaire score, the Patient-Specific Functional Scale score, and the average and worst pain scores in all groups. With the exception of average pain, there were no significant differences between groups for the other measures. The findings indicate that the use of either a rigid or a nonrigid pelvic support belt did not add to the effects provided by exercise and advice.

Background: Painful neuropathy is a very common complication in diabetic patients. Various treatment strategies like manual therapies, conservative management, drug therapy and exercise have been opted for this problem. Studies have shown clinical effectiveness of laser acupuncture as well. On the other hand, Amitryptaline is also a commonly used treatment for this disease. We aim to compare the efficacy of both treatments. Objective: To assess the effect of laser acupuncture in patients suffering from painful diabetic neuropathy and its comparison with standard of care. Patients and Method: This study was conducted in Diabetic and Endocrine Management Center (DEMC) Lahore General Hospital, Lahore, Pakistan. A randomized control trial (RCT) was opted and a total of 164 patients were chosen using Non-probability purposive sampling technique. Pain was graded by using a patient friendly Visual Analogue Score (VAS), scoring from 0 to 10. Treatment was done involving organized fortnightly follow ups. Data of all patients was recorded on Performa and was entered and analyzed for descriptive statistics in PASW 18 (IBM®. SPSS). Results: A total of 164 subjects were included in the study who were subdivided into three groups labeled as A, B and C for laser therapy treatment, amitryptaline treatment and controls respectively. The mean age of subjects was 51.54+/-10.46 in Group A, 49.38+/-10.56 in Group B and 51.70+/-11.43 in Group C. The difference of mean ages in all study groups was statistically insignificant (p-value= 0.469). The average pain score in patients who received laser therapy was 5.95+/-0.91 before treatment, whereas after treatment it was 4.31+/-0.98. The mean pain score in subjects having Amitryptaline before starting the treatment was 6.87+/-0.71 and after treatment, it was 6.23+/-0.98. The mean score for daily life activities in subjects who received laser therapy was 9.562.37 before treatment, while after treatment it was 7.56+/-1.54. The average score for daily life activities in patients having Amitryptaline before starting the treatment was 9.05+/-1.93 and after treatment, it was 8.11+/-1.71. Average depression and anxiety score in patients receiving laser therapy was 9.29+/-2.28 before treatment, whereas after treatment it was found to be 7.42+/-1.91. Similarly, the mean depression and anxiety score in patients of Amitryptaline group before starting the treatment was 9.38+/-2.21 and after treatment, it was 8.38+/-2.14. Conclusion: The mean score in our study reveals that laser therapy shows better outcomes in improvement of pain relief, depression, anxiety and daily life activities compared to amitryptaline in patients of diabetic neuropathy.

To examine family functioning related to sociodemographic and clinical characteristics in youth with cleft lip and/or palate (CL/P). Cross-sectional, multi-site investigation. Six U.S. cleft centers. A diverse sample of 1200 children with CL/P and their parents. Parents completed the Family Environment Scale (FES), which assesses three domains of family functioning: cohesion (or closeness), expressiveness (open expression of feelings), and conflict. Demographic and clinical characteristics were also assessed including race, ethnicity, type of insurance, and surgical recommendations. The FES scores for families seeking team evaluations for their youth with CL/P (mean age = 11.6 years) fall within the average range compared with normative samples. Families receiving surgical recommendations for their youth also had FES scores in the average range, yet families of children recommended for functional surgery reported greater cohesion, expressiveness, and less conflict compared with those recommended for aesthetic surgery (P < .05). For cohesion and expressiveness, significant main effects for race (P = .012, P < .0001, respectively) and ethnicity (P = .004, P < .0001, respectively) were found but not for their interaction. No significant differences were found on the conflict domain. Families with private insurance reported significantly greater cohesion (P < .001) and expressiveness (P < .001) than did families with public insurance. Family functioning across domains was in the average range. However, observed differences by race, ethnicity, type of insurance, and surgical recommendation may warrant consideration in clinical management for patients and families.

Introduction The Clinical Opiate Withdrawal Scale (COWS) is an 11-item clinician-administered scale assessing opioid withdrawal. Though commonly used in clinical practice, it has not been systematically validated. The present study validated the COWS in comparison to the validated Clinical Institute Narcotic Assessment (CINA) scale. Method Opioid-dependent volunteers were enrolled in a residential trial and stabilized on morphine 30 mg given subcutaneously four times daily. Subjects then underwent double-blind, randomized challenges of intramuscularly administered placebo and naloxone (0.4 mg) on separate days, during which the COWS, CINA, and visual analog scale (VAS) assessments were concurrently obtained. Subjects completing both challenges were included (N=46). Correlations between mean peak COWS and CINA scores as well as self-report VAS questions were calculated. Results Mean peak COWS and CINA scores of 7.6 and 24.4, respectively, occurred on average 30 minutes post-injection of naloxone. Mean COWS and CINA scores 30 minutes after placebo injection were 1.3 and 18.9, respectively. The Pearson correlation coefficient for peak COWS and CINA scores during the naloxone challenge session was 0.85 (p<0.001). Peak COWS scores also correlated well with peak VAS self-report scores of bad drug effect (r=0.57, p<0.001) and feeling sick (r=0.57, p<0.001), providing additional evidence of concurrent validity. Placebo was not associated with any significant elevation of COWS, CINA, or VAS scores, indicating discriminant validity. Cronbach’s alpha for the COWS was 0.78, indicating good internal consistency (reliability). Discussion COWS, CINA, and certain VAS items are all valid measurement tools for acute opiate withdrawal.

Functional evaluation is a cornerstone of multidimensional geriatric assessment; however, little is known of the clinical value of standardized performance-based assessment in the acute care setting. The aim of this study was to evaluate the clinical correlates and short-term predictive value of the Short Physical Performance Battery (SPPB) in older patients admitted to the hospital for an acute medical event. We enrolled 92 women and men 65 years old or older who were able to walk, who had a Mini-Mental State Examination (MMSE) score > or =18, and who were admitted to the hospital with a clinical diagnosis of congestive heart failure, pneumonia, chronic obstructive pulmonary disease (COPD), or minor stroke. The SPPB was assessed at hospital admission and discharge. Self-report functional assessment included basic activities of daily living (ADL) and instrumental activities of daily living (IADL). Spearman's rank correlation coefficients and multivariable linear regression analyses were used to study the association of SPPB score and functional and clinical characteristics, including length of hospital stay. The mean age was 77.7 years (range 65-94 years), 49% were female, 64.1% had congestive heart failure, 16% COPD, 13.1% pneumonia, and 6.5% minor stroke. At hospital admission the mean SPPB score was 6.0 +/- 2.7. SPPB scores were inversely correlated with age, the severity of the index disease, and IADL and ADL difficulty 2 weeks before hospital admission (p <.01), and were directly correlated with MMSE score (p =.002). On average, SPPB score increased 1 point (+0.97, standard error of the mean = 0.2; p for paired t test <.001) from baseline to hospital discharge assessment. After adjustment for potential confounders, baseline SPPB score was significantly associated with the length of hospital stay (p <.007). In older acute care inpatients, SPPB is a valid indicator of functional and clinical status. SPPB score at hospital admission is an independent predictor of the length of hospital stay.

Management of patients with obstructed defecation syndrome is still controversial. To analyze the efficacy of clinical, clinical treatment followed by biofeedback, and surgical treatment in patients with obstructed defecation, rectocele and multiple dysfunctions evaluated with echodefecography. The study included 103 females aged 26-84 years with obstructed defecation, grade-II/III rectocele and multiple dysfunctions on echodefecography. Patients were distributed into three treatment groups and constipation scores were assigned. Group I: 34 (33%) patients with significant improvement of symptoms through clinical management only. Group II: 14 (14%) with improvement through clinical treatment plus biofeedback. Group III: 55 (53%) referred to surgery due to treatment failure. Group I: 20 (59%) patients had grade-II rectocele, 14 (41%) grade-III. Obstructed defecation syndrome was associated with intussusception (41%), mucosal prolapse (41%), anismus (29%), enterocele (9%) or 2 dysfunctions (23%). The average constipation score decreased significantly from 11 to 5. Group II: 11 (79%) grade-II rectocele, 3 (21%) grade-III, associated with intussusception (7%), mucosal prolapse (43%), anismus (71%) or 2 dysfunctions (29%). There was significant decrease in constipation score from 13 to 6. Group III: 8 (15%) grade-II rectocele, 47 (85%) grade-III, associated with intussusception (42%), mucosal prolapse (40%) or 2 dysfunctions (32%). The constipation score remained unchanged despite clinical treatment and biofeedback. Twenty-three underwent surgery had a significantly decrease in constipation score from 12 to 4. The remaining 32 (31%) patients which 22 refused surgery, 6 had low anal pressure and 4 had slow transit. Approximately 50% of patients with obstructed defecation, rectocele and multiple dysfunctions presented a satisfactory response to clinical treatment and/or biofeedback. Surgical repair was mainly required in patients with grade-III rectocele whose constipation scores remained high despite all efforts.

Despite the increasing use of opioid analgesics for chronic pain management, it is unclear whether opioid dose escalation leads to better pain relief during chronic opioid therapy. In this study, we retrospectively analyzed clinical data collected from the Massachusetts General Hospital (MGH) Center for Pain Medicine over a 7-year period. We examined 1) the impact of opioid dose adjustment (increase or decrease) on clinical pain score, 2) gender and age differences in response to opioid therapy, and 3) the influence of clinical pain conditions on the opioid analgesic efficacy. A total of 109 subjects met the criteria for data collection. We found that neither opioid dose increase, nor decrease, correlated with point changes in clinical pain score in a subset of chronic pain patients over a prolonged course of opioid therapy (an average of 704 days). This lack of correlation was consistent regardless of the type of chronic pain including neuropathic, nociceptive, or mixed pain conditions. Neither gender nor age differences showed a significant influence on the clinical response to opioid therapy in these subjects. These results suggest that dose adjustment during opioid therapy may not necessarily alter long-term clinical pain score in a group of chronic pain patients and that individualized opioid therapy based on the clinical effectiveness should be considered to optimize the treatment outcome. Perspectives The study reports a relationship, or lack thereof, between opioid dose change and clinical pain score in a group of chronic pain patients. The study also calls for further investigation into the effectiveness of opioid therapy in the management of chronic non-malignant pain conditions. PMID:23452826

The methodological quality of controlled clinical trials (CCTs) of physiotherapeutic treatment modalities for myofascial trigger points (MTrP) has not been investigated yet. To detect the methodological quality of CCTs for physiotherapy treatments of MTrPs and demonstrating the possible increase over time. Systematic review. A systematic search was conducted in two databases, Physiotherapy Evidence Database (PEDro) and Medicine Medical Literature Analysis and Retrieval System online (MEDLINE), using the same keywords and selection procedure corresponding to pre-defined inclusion criteria. The methodological quality, assessed by the 11-item PEDro scale, served as outcome measure. The CCTs had to compare at least two interventions, where one intervention had to lay within the scope of physiotherapy. Participants had to be diagnosed with myofascial pain syndrome or trigger points (active or latent). A total of n = 230 studies was analysed. The cervico-thoracic region was the most frequently treated body part (n = 143). Electrophysical agent applications was the most frequent intervention. The average methodological quality reached 5.5 on the PEDro scale. A total of n = 6 studies scored the value of 9. The average PEDro score increased by 0.7 points per decade between 1978 and 2015. The average PEDro score of CCTs for MTrP treatments does not reach the cut-off of 6 proposed for moderate to high methodological quality. Nevertheless, a promising trend towards an increase of the average methodological quality of CCTs for MTrPs was recorded. More high-quality CCT studies with thorough research procedures are recommended to enhance methodological quality. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Midwifery support and care led by midwives is the most appropriate strategy to improve maternal and newborn health. The Government of Ethiopia has recently improved the availability of midwives by scaling up pre-service education. However, the extent to which graduating students acquire core competencies for safe and effective practice is not known. The purpose of this study was to evaluate the quality of midwifery education by assessing the competence of graduating midwifery students. We conducted a cross-sectional study to assess the competence of students who completed basic midwifery education in Ethiopia in 2013. We interviewed students to obtain their perceptions of the sufficiency and quality of teachers and educational resources and processes. We assessed achievement of essential midwifery competencies through direct observation, using a 10-station Objective Structured Clinical Examination (OSCE). We calculated average percentage scores of performance for each station and an average summary score for all stations. Chi-square test, independent sample t test, and linear regression analysis were used to assess the statistical significance of differences and associations. We assessed 484 graduating students from 25 public training institutions. Majority of students rated the learning environment unfavorably on 8 out of 10 questions. Only 32 % of students managed 20 or more births during training, and just 6 % managed 40 or more births. Students' overall average competence score was 51.8 %; scores ranged from 32.2 % for manual vacuum aspiration to 69.4 % for active management of the third stage of labor. Male gender, reporting sufficient clinical experience, and managing greater numbers of births during training were significant predictors of higher competence scores. The quality of pre-service midwifery education needs to be improved, including strengthening of the learning environment and quality assurance systems. In-service training and mentoring to fill competence gaps of new graduates is also essential.

There is major controversy surrounding the use of hemiarthroplasty as compared with total shoulder arthroplasty for glenohumeral osteoarthritis, and long-term clinical outcomes of hemiarthroplasty are lacking. Of a cohort of thirty patients (thirty-one shoulders) who were treated with hemiarthroplasty for glenohumeral osteoarthritis and followed longitudinally at our institution, twenty-five were available for long-term follow-up; five died, and one refused to participate. Three of the five patients who died had revision arthroplasty before death, and the data from those three were therefore included in the final follow-up (final follow-up data therefore included twenty-seven patients and twenty-eight shoulders). Follow-up through phone conversations and postal mail surveys included the following: Short Form-36, American Shoulder and Elbow Surgeons (ASES) shoulder outcome score, EuroQol, Simple Shoulder Test, modified Neer Score, and a unique, validated self-administered range-of-motion questionnaire. Correlations between clinical outcome and age, type of glenoid wear, and cause of osteoarthritis were determined. The average follow-up was 17.2 years (range, thirteen to twenty-one years). There were eight revisions (three of fifteen shoulders with concentric glenoids, and five of sixteen shoulders with eccentric glenoids). For those shoulders not revised, the average ASES score was 70.54 (range, 36.67 to 91.67). Overall, active shoulder forward elevation and external rotation with the arm at 90° of abduction increased from 104° preoperatively to 141.8° (range, 45° to 180°) and 20.7° to 61.0° (range, 30° to 90°), respectively (p < 0.05), at the time of final follow-up. Of those who required revision arthroplasty, the average patient age at the time of the index procedure was 51.0 years (range, twenty-six to eighty-one years), while those not requiring revision averaged 57.1 years (range, twenty-seven to sixty-three years). The overall Neer satisfaction rating was 25%. The average Neer score and Neer rating for unrevised cases were significantly higher for concentric glenoid wear compared with eccentric glenoid wear (p = 0.015 and p = 0.001, respectively). Patients who had concentric glenoid wear had higher EuroQol scores (p = 0.020). The average Neer scores were 65.29 (range, forty-seven to seventy-eight) for primary osteoarthritis and 54.46 (range, forty to seventy-seven) for secondary osteoarthritis (p = 0.036). Only 25% of patients with glenohumeral osteoarthritis treated with shoulder hemiarthroplasty are satisfied with their outcome at an average of seventeen years after the operation. Patients with concentric glenoid wear and primary osteoarthritis have better outcomes than those with eccentric glenoid wear and secondary osteoarthritis do, but patients in both groups experienced deterioration of results over time.

In this study, we evaluated the quality management system for voluntary and provider-initiated point-of-care HIV testing in primary healthcare (PHC) clinics in rural KwaZulu-Natal (KZN), South Africa. We conducted a quality assessment audit in eleven PHC clinics that offer voluntary HIV testing and counselling in rural KZN, South Africa from August 2015 to October 2016. All the participating clinics were purposively selected from the province-wide survey of diagnostic services. We completed an on-site monitoring checklist, adopted from the WHO guidelines for assuring accuracy and reliability of HIV rapid tests, to assess the quality management system for HIV rapid testing at each clinic. To determine clinic's compliance to WHO quality standards for HIV rapid testing the following quality measure was used, a 3-point scale (high, moderate and poor). A high score was defined as a percentage rating of 90 to 100%, moderate was defined as a percentage rating of 70 to 90%, and poor was defined as a percentage rating of less than 70%. Clinic audit scores were summarized and compared. We employed Pearson pair wise correlation coefficient to determine correlations between clinics audit scores and clinic and clinics characteristics. Linear regression model was computed to estimate statistical significance of the correlates. Correlations were reported as significant at p ≤0.05. Nine out of 11 audited rural PHC clinics are located outside 20Km of the nearest town and hospital. Majority (18.2%) of the audited rural PHC clinics reported that HIV rapid test was performed by HIV lay counsellors. Overall, ten clinics were rated moderate, in terms of their compliance to the stipulated WHO guidelines. Audit results showed that rural PHC clinics' average rating score for compliance to the WHO guidelines ranged between 64.4% (CI: 44%- 84%) and 89.2% (CI: 74%- 100%).Ten out of eleven of the clinics were rated as moderate (70-89%). All clinic have scored highest for the following audit component: equipment; process control and specimen management; and facility ad safety, with 100%. Clinics obtained the lowest scores for the assessment audit component followed by process improvement and organisation, with 40.9% (CI: 15.7-66.1%), 45.5% (CI: 10.4-80.5%) and 56.8% (CI: 31.8 81.8%), respectively. A statistically significant correlation was observed between the following: category of staff performing the HIV rapid tests in the audited clinics and service and satisfactory audit component; weekly average number of patients using the audited PHC clinics and service and satisfactory audit component; number of HIV lay counsellors in the audited clinics and quality control audit component with p<0.05. In the small audit of primary healthcare clinics located within the rural part of KwaZulu-Natal, results revealed an overall moderate rating of the quality management system for rapid HIV testing. Improvements in the organisation, quality control, process improvement and assessment components could enable a higher quality assurance rating for rural HIV testing in KwaZulu-Natal.

OBJECTIVE The authors conducted a study to evaluate the long-term clinical and radiographic outcomes of vertebral column resection (VCR) for kyphosis in patients with cured spinal tuberculosis. METHODS This was a retrospective study. Between 2003 and 2009, 28 consecutive patients with cured spinal tuberculosis underwent VCR for kyphosis in which the target vertebra was removed completely. Autologous iliac crest bone graft or titanium mesh packed with autograft was placed into the osteotomy gap to reconstruct the spine for anterior column stability. Posterior pedicle screw fixation and fusion were typically performed. Radiographic parameters, including kyphosis angle and sagittal balance, were measured, and visual analog scale score, America Spinal Injury Association grade, Scoliosis Research Society outcome instrument (SRS-22) score, Oswestry Disability Index, patient satisfaction index, and long-term complications were evaluated. RESULTS This study included 12 males and 16 females, with an average age of 20.9 years at the time of surgery. The average follow-up was 96.9 months. No deaths occurred in this study. At the final follow-up, the kyphosis angle improved from the preoperative average of 70.7° to the final follow-up average of 30.2°, and the average kyphosis correction loss was 8.5°. The sagittal balance averaged 15.4 mm before surgery, 2.8 mm after surgery, and 5.4 mm at the final followup. Thirteen patients showed improvement of more than 1 America Spinal Injury Association grade. The visual analog scale, Oswestry Disability Index, and SRS-22 scores improved significantly, and the overall satisfaction rate was 92.9%. Adjacent-segment degeneration occurred in 3 patients. No severe instrumentation-related complications were observed. CONCLUSIONS The long-term safety and efficacy of the VCR technique for treating spinal tuberculosis-related kyphosis were favorable, and no severe late-stage complications appeared. Lumbar tubercular kyphosis showed a tendency for sagittal decompensation within the first 3 postoperative years. Cases of adjacent-segment degenerations were relatively few and mild without clinical symptoms.

Purpose To determine if speech error patterns in preschoolers with speech sound disorders (SSDs) predict articulation and phonological awareness (PA) outcomes almost four years later. Method Twenty-five children with histories of preschool SSDs (and normal receptive language) were tested at an average age of 4;6 and followed up at 8;3. The frequency of occurrence of preschool distortion errors, typical substitution and syllable structure errors, and atypical substitution and syllable structure errors were used to predict later speech sound production, PA, and literacy outcomes. Results Group averages revealed below-average school-age articulation scores and low-average PA, but age-appropriate reading and spelling. Preschool speech error patterns were related to school-age outcomes. Children for whom more than 10% of their speech sound errors were atypical had lower PA and literacy scores at school-age than children who produced fewer than 10% atypical errors. Preschoolers who produced more distortion errors were likely to have lower school-age articulation scores. Conclusions Different preschool speech error patterns predict different school-age clinical outcomes. Many atypical speech sound errors in preschool may be indicative of weak phonological representations, leading to long-term PA weaknesses. Preschool distortions may be resistant to change over time, leading to persisting speech sound production problems. PMID:23184137

To determine if speech error patterns in preschoolers with speech sound disorders (SSDs) predict articulation and phonological awareness (PA) outcomes almost 4 years later. Twenty-five children with histories of preschool SSDs (and normal receptive language) were tested at an average age of 4;6 (years;months) and were followed up at age 8;3. The frequency of occurrence of preschool distortion errors, typical substitution and syllable structure errors, and atypical substitution and syllable structure errors was used to predict later speech sound production, PA, and literacy outcomes. Group averages revealed below-average school-age articulation scores and low-average PA but age-appropriate reading and spelling. Preschool speech error patterns were related to school-age outcomes. Children for whom >10% of their speech sound errors were atypical had lower PA and literacy scores at school age than children who produced <10% atypical errors. Preschoolers who produced more distortion errors were likely to have lower school-age articulation scores than preschoolers who produced fewer distortion errors. Different preschool speech error patterns predict different school-age clinical outcomes. Many atypical speech sound errors in preschoolers may be indicative of weak phonological representations, leading to long-term PA weaknesses. Preschoolers' distortions may be resistant to change over time, leading to persisting speech sound production problems.

This study analyzed the relationship between psychosocial factors and progression in intima media thickness (IMT). In 1998 and 2002, 95 healthy participants underwent a clinical examination, including ultrasound of the arteria carotis communis (ACC). IMT progression in women was 0.033 mm/year (SD=0.033) and in men 0.048 mm/year (SD=0.033). For cohabiting women as opposed to single women, the means for total IMT progression over the 4 years were, respectively, 0.137 (SE=0.019) and 0.016 (SE=0.048) mm. For women with above average as opposed to below average mean scores of effort, IMT progression were 0.149 (SE=0.026) and 0.098 (SE=0.024) mm, respectively. For men without children as opposed to men with children, mean scores for IMT progression were 0.231 (SE=0.029) and 0.137 (SE=0.028) mm, respectively. For men above average as opposed to those below average, scores of effort-reward imbalance IMT progression were 0.216 (SE=0.030) and 0.155 (SE=0.027) mm, respectively. Adjustment for confounders did not change the results significantly. We found that psychosocial factors were independent significant predictors of IMT progression. The associations were different between the genders.

Given the recognition that disease-modifying therapies should focus on earlier Parkinson's disease stages, trial enrollment based purely on clinical criteria poses significant challenges. The goal herein was to determine the utility of dopamine transporter neuroimaging as an enrichment biomarker in early motor Parkinson's disease clinical trials. Patient-level longitudinal data of 672 subjects with early-stage Parkinson's disease in the Parkinson's Progression Markers Initiative (PPMI) observational study and the Parkinson Research Examination of CEP-1347 Trial (PRECEPT) clinical trial were utilized in a linear mixed-effects model analysis. The rate of worsening in the motor scores between subjects with or without a scan without evidence of dopamine transporter deficit was different both statistically and clinically. The average difference in the change from baseline of motor scores at 24 months between biomarker statuses was -3.16 (90% confidence interval [CI] = -0.96 to -5.42) points. Dopamine transporter imaging could identify subjects with a steeper worsening of the motor scores, allowing trial enrichment and 24% reduction of sample size. Published 2017.

The purpose of this study was to evaluate the clinical results of distal chevron osteotomy performed in conjunction with selective lateral soft tissue release. The criterion for doing a lateral soft tissue release was assessed by determining the ease and completeness of passive hallux valgus correction at the time of surgery. Between August 2005 and November 2007, 48 feet in 43 patients classified as having mild to moderate hallux valgus were retrospectively studied. Distal chevron osteotomy without lateral soft tissue release was performed in 26 cases (Group 1) when passive correction of the hallux valgus deformity was possible. Distal chevron osteotomy with lateral soft tissue release was performed in 22 cases (Group 2) when passive correction was not possible. Average followup was 23 (range, 12 to 28) months. Clinical results were assessed using radiographic parameters [hallux valgus angle (HVA), first and second intermetatarsal angle (1,2 IMA)], AOFAS scale and patient's subjective satisfaction. For Group 1: the average correction of HVA was 12.8 degrees, the average correction of IMA was 4.7 degrees, and the AOFAS score improved an average of 29.2 points at the last followup. Thirteen patients were very satisfied and ten patients were satisfied with the results. No patient was dissatisfied. For Group 2: the average correction of HVA was 19.1 degrees, the average correction of IMA was 7 degrees and AOFAS score improved at an average of 31.8 points at the last followup. Twelve patients were very satisfied, seven patients were satisfied and one patient, who had stiffness of the first metatarsophalangeal joint, was dissatisfied with the result. Distal chevron osteotomy with selective lateral soft tissue release based on the ability to passively correct the hallux valgus deformity lead to safe and stable correction.

The primary objective was to determine whether technical and nontechnical performances were in some way correlated during immersive simulation. Performance was measured among French Emergency Medical Service workers at an individual and a team level. Secondary objectives were to assess stress response through collection of physiologic markers (salivary cortisol, heart rate, the proportion derived by dividing the number of interval differences of successive normal-to-normal intervals > 50 ms by the total number of normal-to-normal intervals [pNN50], low- and high-frequency ratio) and affective data (self-reported stress, confidence, and dissatisfaction), and to correlate them to performance scores. Prospective observational study performed as part of a larger randomized controlled trial. Medical simulation laboratory. Forty-eight participants distributed among 12 Emergency Medical System teams. Individual and team performance measures and individual stress response were assessed during a high-fidelity simulation. Technical performance was assessed by the intraosseous access performance scale and the Team Average Performance Assessment Scale; nontechnical performance by the Behavioral Assessment Tool for leaders, and the Clinical Teamwork Scale. Stress markers (salivary cortisol, heart rate, pNN50, low- and high-frequency ratio) were measured both before (T1) and after the session (T2). Participants self-reported stress before and during the simulation, self-confidence, and perception of dissatisfaction with team performance, rated on a scale from 0 to 10. Scores (out of 100 total points, mean ± SD) were intraosseous equals to 65.6 ± 14.4, Team Average Performance Assessment Scale equals to 44.6 ± 18.1, Behavioral Assessment Tool equals to 49.5 ± 22.0, Clinical Teamwork Scale equals to 50.3 ± 18.5. There was a strong correlation between Behavioral Assessment Tool and Clinical Teamwork Scale (Rho = 0.97; p = 0.001), and Behavioral Assessment Tool and Team Average Performance Assessment Scale (Rho = 0.73; p = 0.02). From T1 to T2, all stress markers (salivary cortisol, heart rate, pNN50, and low- and high-frequency ratio) displayed an increase in stress level (p < 0.001 for all). Self-confidence was positively correlated with performance (Clinical Teamwork Scale: Rho = 0.47; p = 0.001, Team Average Performance Assessment Scale: Rho = 0.46; p = 0.001). Dissatisfaction was negatively correlated with performance (Rho = -0.49; p = 0.0008 with Behavioral Assessment Tool, Rho = -0.47; p = 0.001 with Clinical Teamwork Scale, Rho = -0.51; p = 0.0004 with Team Average Performance Assessment Scale). No correlation between stress response and performance was found. There was a positive correlation between leader (Behavioral Assessment Tool) and team (Clinical Teamwork Scale and Team Average Performance Assessment Scale) performances. These performance scores were positively correlated with self-confidence and negatively correlated with dissatisfaction.

To assess the adequacy of 5 controlled medical terminologies (International Classification of Diseases 9, Clinical Modification [ICD9-CM]; Current Procedural Terminology 4 [CPT-4]; Systematized Nomenclature of Medicine, Clinical Terms [SNOMED-CT]; Logical Identifiers, Names, and Codes [LOINC]; Medical Entities Dictionary [MED]) for representing concepts in ophthalmology. Noncomparative case series. Twenty complete ophthalmology case presentations were sequentially selected from a publicly available ophthalmology journal. Each of the 20 cases was parsed into discrete concepts, and each concept was classified along 2 axes: (1) diagnosis, finding, or procedure and (2) ophthalmic or medical concept. Electronic or paper browsers were used to assign a code for every concept in each of the 5 terminologies. Adequacy of assignment for each concept was scored on a 3-point scale. Findings from all 20 case presentations were combined and compared based on a coverage score, which was the average score for all concepts in that terminology. Adequacy of assignment for concepts in each terminology, based on a 3-point Likert scale (0, no match; 1, partial match; 2, complete match). Cases were parsed into 1603 concepts. SNOMED-CT had the highest mean overall coverage score (1.625+/-0.667), followed by MED (0.974+/-0.764), LOINC (0.781+/-0.929), ICD9-CM (0.280+/-0.619), and CPT-4 (0.082+/-0.337). SNOMED-CT also had higher coverage scores than any of the other terminologies for concepts in the diagnosis, finding, and procedure categories. Average coverage scores for ophthalmic concepts were lower than those for medical concepts. Controlled terminologies are required for electronic representation of ophthalmology data. SNOMED-CT had significantly higher content coverage than any other terminology in this study.

Fractures of the acetabulum show a high, long-term complication rate. The aim of the present study was to determine the predictive value of clinical scoring and standardized, simplified gait analysis on the outcome after these fractures. Forty-one patients with acetabular fractures treated between 2008 and 2013 and available, standardized video recorded aftercare were identified from a prospective database. A visual gait score was used to determine the patients walking abilities 6-m postoperatively. Clinical (Merle d'Aubigne and Postel score, visual analogue scale pain, EQ5d) and radiological scoring (Kellgren-Lawrence score, postoperative computed tomography, and Matta classification) were used to perform correlation and multivariate regression analysis. The average patient age was 48 y (range, 15-82 y), six female patients were included in the study. Mean follow-up was 1.6 y (range, 1-2 y). Moderate correlation between the gait score and outcome (versus EQ5d: r s  = 0.477; versus Merle d'Aubigne: r s  = 0.444; versus Kellgren-Lawrence: r s  = -0.533), as well as high correlation between the Merle d'Aubigne score and outcome were seen (versus EQ5d: r s  = 0.575; versus Merle d'Aubigne: r s  = 0.776; versus Kellgren-Lawrence: r s  = -0.419). Using a multivariate regression model, the 6 m gait score (B = -0.299; P < 0.05) and early osteoarthritis development (B = 1.026; P < 0.05) were determined as predictors of final osteoarthritis. A good fit of the regression model was seen (R 2  = 904). Easy and available clinical scoring (gait score/Merle d'Aubigne) can predict short-term radiological and functional outcome after acetabular fractures with sufficient accuracy. Decisions on further treatment and interventions could be based on simplified gait analysis. Copyright © 2016 Elsevier Inc. All rights reserved.

The relationships among clinical outcomes, academic success, and predictors used to screen applicants for entrance into a Master in Occupational Therapy Program (MOT) were examined. The dependent variables were grade point average in occupational therapy courses (OT-GPA), client therapy outcomes at the clinic, and ratings of MOT students by Level II Fieldwork supervisors. Predictor variables included undergraduate GPA, scores on the Graduate Record Examination (GRE), and an essay. Both undergraduate GPA and scores on the GRE were found to predict OT-GPA. The analytical section of the GRE was also positively correlated with fieldwork supervisors' ratings of students.

Although contentious most medical schools interview potential students to assess personal abilities such as communication. To investigate any differences in clinical communication skills (CCS) between first year students admitted to UQ medical school with or without an admissions interview. A retrospective analysis of 1495 student assessment scores obtained after structured communication skills training (CCS) between 2007 and 2010. The average assessment score was 3.76 ([95% CI, 3.73-3.78]) and adjusting for student characteristics, showed no main effect for interview (p = 0.89). The strongest predictor of scores was gender with females achieving significantly higher scores (3.91 [95% CI, 3.54-4.28] vs. 3.76 [95% CI, 3.39-4.13]; p ≤ 0.001). Data show no differences in post-training assessment measures between students who were interviewed during selection or not. Further research about the quality and retention of communications skills after training is warranted.

Introduction Rapid HIV tests have improved access to HIV diagnosis and treatment by providing quick and convenient testing in rural clinics and resource-limited settings. In this study, we evaluated the quality management system for voluntary and provider-initiated point-of-care HIV testing in primary healthcare (PHC) clinics in rural KwaZulu-Natal (KZN), South Africa. Material and methods We conducted a quality assessment audit in eleven PHC clinics that offer voluntary HIV testing and counselling in rural KZN, South Africa from August 2015 to October 2016. All the participating clinics were purposively selected from the province-wide survey of diagnostic services. We completed an on-site monitoring checklist, adopted from the WHO guidelines for assuring accuracy and reliability of HIV rapid tests, to assess the quality management system for HIV rapid testing at each clinic. To determine clinic’s compliance to WHO quality standards for HIV rapid testing the following quality measure was used, a 3-point scale (high, moderate and poor). A high score was defined as a percentage rating of 90 to 100%, moderate was defined as a percentage rating of 70 to 90%, and poor was defined as a percentage rating of less than 70%. Clinic audit scores were summarized and compared. We employed Pearson pair wise correlation coefficient to determine correlations between clinics audit scores and clinic and clinics characteristics. Linear regression model was computed to estimate statistical significance of the correlates. Correlations were reported as significant at p ≤0.05. Results Nine out of 11 audited rural PHC clinics are located outside 20Km of the nearest town and hospital. Majority (18.2%) of the audited rural PHC clinics reported that HIV rapid test was performed by HIV lay counsellors. Overall, ten clinics were rated moderate, in terms of their compliance to the stipulated WHO guidelines. Audit results showed that rural PHC clinics’ average rating score for compliance to the WHO guidelines ranged between 64.4% (CI: 44%– 84%) and 89.2% (CI: 74%– 100%).Ten out of eleven of the clinics were rated as moderate (70–89%). All clinic have scored highest for the following audit component: equipment; process control and specimen management; and facility ad safety, with 100%. Clinics obtained the lowest scores for the assessment audit component followed by process improvement and organisation, with 40.9% (CI: 15.7–66.1%), 45.5% (CI: 10.4–80.5%) and 56.8% (CI: 31.8 81.8%), respectively. A statistically significant correlation was observed between the following: category of staff performing the HIV rapid tests in the audited clinics and service and satisfactory audit component; weekly average number of patients using the audited PHC clinics and service and satisfactory audit component; number of HIV lay counsellors in the audited clinics and quality control audit component with p<0.05. Discussion In the small audit of primary healthcare clinics located within the rural part of KwaZulu-Natal, results revealed an overall moderate rating of the quality management system for rapid HIV testing. Improvements in the organisation, quality control, process improvement and assessment components could enable a higher quality assurance rating for rural HIV testing in KwaZulu-Natal. PMID:28829801

Student Evaluations, Outcomes, and National Licensure Examinations in Radiology Education: A Narrative Review of the Literature.

Linaker, Kathleen L

2015-12-01

The purpose of this study was to examine literature on radiological student evaluation and outcome assessments including national board examinations. A review of the literature was performed using relevant key words. Articles were retrieved through December 2012 using PubMed, ScienceDirect, ERIC, Proquest, and ICL databases along with a manual review of references. Of the 4716 unique abstracts reviewed by the author, 54 were found to be relevant to the purpose of this study. Student grade point average correlates with board scores in the nursing, chiropractic, and medical professions. Scores on the chiropractic college admission test and undergraduate grade point average correlate with success in professional college. There is a correlation between board scores and college attended. Board preparation programs do not appear to affect board examination scores. Although evaluations can be effective teaching tools, they are not used by many radiology programs. Some programs have inadequate evaluations and do not allow students to review their evaluations. There are no definitive links between mastery of radiology and specific evaluations, outcomes, or pre-professional/clinical grades. Studies suggest that board examination scores reflect long-term mastery of knowledge rather than short-term memorization of facts.

Mozambique suffers from critical shortages of healthcare workers including non-physician clinicians, Tecnicos de Medicina Geral (TMGs), who are often senior clinicians in rural health centres. The Mozambique Ministry of Health and the International Training and Education Center for Health, University of Washington, Seattle, revised the national curriculum to improve TMG clinical knowledge and skills. To evaluate the effort, data was collected at graduation and 10 months later from pre-revision (initial) and revised curriculum TMGs to determine the following: (1) Did cohorts trained in the revised curriculum score higher on measurements of clinical knowledge, physical exam procedures, and solving clinical case scenarios than those trained in the initial curriculum; (2) Did TMGs in both curricula retain their knowledge over time (from baseline to follow-up); and (3) Did skills and knowledge retention differ over time by curricula? Post-graduation and over time results are presented. t-tests examine differences in scores between curriculum groups. Univariate and multivariate linear regression models assess curriculum-related, demographic, and workplace factors associated with scores on each of three evaluation methods at the p < 0.05 level. Paired t-tests examine within-group changes over time. ANOVA models explore differences between Health Training Institutes (HTIs). Generalized estimating equations determine whether change in scores over time differed by curricula. Mean scores of initial curriculum TMGs at follow-up were 52.7%, 62.6%, and 40.0% on the clinical cases, knowledge test, and physical exam, respectively. Averages were significantly higher among the revised group for clinical cases (60.2%; p < 0.001) and physical exam (47.6%; p < 0.001). HTI was influential on clinical case and physical exam scores. Between graduation and follow-up, clinical case and physical exam scores decreased significantly for initial curriculum students; clinical case scores increased significantly among revised curriculum TMGs. Although curriculum revision had limited effect, marginal improvements in the revised group show promise that these TMGs may have increased ability to synthesize clinical information. Weaknesses in curriculum and practicum implementation likely compromised the effect of curriculum revision. An improvement strategy that includes strengthened TMG training, greater attention to pre-service clinical practice, and post-graduation mentoring may be more advantageous than curriculum revision, alone, to improve care provided by TMGs.

Taylor, Frederick; Levine, Laurence

2010-01-01

The efficacy of oral clomiphene citrate (CC) in the treatment of male hypogonadism and male infertility (MI) with low serum testosterone and normal gonadotropin levels has been reported. The aim of this article is to evaluate CC and testosterone gel replacement therapy (TGRT) with regard to biochemical and clinical efficacy and cost. The main outcome measures were change in serum testosterone with CC and TGRT therapy, and change in the androgen deficiency in aging male (ADAM) questionnaire scores with CC therapy. Men receiving CC or TGRT with either Androgel 1% or Testim 1% for hypogonadism (defined as testosterone < 300 ng/mL) or MI were included. Serum values were collected 1-2 months after treatment initiation and semi-annually thereafter. Retrospective data collection was performed via chart review. Subjective follow up of patients receiving CC was performed via telephone interview using the ADAM questionnaire. A hundred and four men (65 CC and 39 TGRT) were identified who began CC (50 mg every other day) or TGRT (5 g). Average age (years) was 42(CC) vs. 57 (TGRT). Average follow up was 23 months (CC, range 8-40 months) vs. 46 months (TGRT, range 6-149 months). Average posttreatment testosterone was 573 ng/dL in the CC group and 553 ng/dL in the TGRT group (P value < 0.001). The monthly cost of Testim 1% (5 gm daily) is $270, Androgel 1% (5 gm daily) is $265, and CC (50 mg every other day) is $83. Among CC patients, the average pretreatment ADAM score was 4.9 vs. 2.1 at follow up (P < 0.05). Average pretreatment ADAM sexual function domain score was 0.76 vs. 0.23 at follow up (P < 0.05). There were no adverse events reported. CC represents a treatment option for men with hypogonadism, demonstrating biochemical and clinical efficacy with few side effects and lower cost as compared with TGRT.

Methods  The AC and Canine Brief Pain Inventory (CBPI) owner questionnaires of 62 dogs with OA were compared with daily environmental variables including the following: average temperature (°C), high temperature (°C), low temperature (°C), relative humidity (%), total precipitation (mm), average barometric pressure (hPa) and total daylight hours. Results  Daily AC significantly correlated with average temperature and total daylight hours, but average temperature and total daylight hours accounted for less than 1% of variation in AC. No other significant relationships were found between daily AC and daily high temperature, low temperature, relative humidity, total precipitation or average barometric pressure. No statistical relationship was found between daily AC and the CBPI, nor between environmental variables and the CBPI. Canine Brief Pain Inventory scores for pain severity and pain interference decreased significantly over the test period. Clinical Significance  The relationship between daily AC and average temperature and total daylight hours was significant, but unlikely to be clinically significant. Thus, environmental variables do not appear to have a clinically relevant bias on AC or owner CBPI questionnaires. The decrease over time in CBPI pain severity and pain interference values suggests owners completing the CBPI in this study were influenced by a caregiver placebo effect. Schattauer GmbH Stuttgart.

In the Multiple Myeloma clinical registry at Heidelberg University Hospital, most data are extracted from discharge letters. Our aim was to analyze if it is possible to make the manual documentation process more efficient by using methods of natural language processing for multiclass classification of free-text diagnostic reports to automatically document the diagnosis and state of disease of myeloma patients. The first objective was to create a corpus consisting of free-text diagnosis paragraphs of patients with multiple myeloma from German diagnostic reports, and its manual annotation of relevant data elements by documentation specialists. The second objective was to construct and evaluate a framework using different NLP methods to enable automatic multiclass classification of relevant data elements from free-text diagnostic reports. The main diagnoses paragraph was extracted from the clinical report of one third randomly selected patients of the multiple myeloma research database from Heidelberg University Hospital (in total 737 selected patients). An EDC system was setup and two data entry specialists performed independently a manual documentation of at least nine specific data elements for multiple myeloma characterization. Both data entries were compared and assessed by a third specialist and an annotated text corpus was created. A framework was constructed, consisting of a self-developed package to split multiple diagnosis sequences into several subsequences, four different preprocessing steps to normalize the input data and two classifiers: a maximum entropy classifier (MEC) and a support vector machine (SVM). In total 15 different pipelines were examined and assessed by a ten-fold cross-validation, reiterated 100 times. For quality indication the average error rate and the average F1-score were conducted. For significance testing the approximate randomization test was used. The created annotated corpus consists of 737 different diagnoses paragraphs with a total number of 865 coded diagnosis. The dataset is publicly available in the supplementary online files for training and testing of further NLP methods. Both classifiers showed low average error rates (MEC: 1.05; SVM: 0.84) and high F1-scores (MEC: 0.89; SVM: 0.92). However the results varied widely depending on the classified data element. Preprocessing methods increased this effect and had significant impact on the classification, both positive and negative. The automatic diagnosis splitter increased the average error rate significantly, even if the F1-score decreased only slightly. The low average error rates and high average F1-scores of each pipeline demonstrate the suitability of the investigated NPL methods. However, it was also shown that there is no best practice for an automatic classification of data elements from free-text diagnostic reports.

Chronic pelvic pain is a debilitating condition. It is unknown if there is a clinical phenotype for adhesive disorders. This study aimed to determine if the presence or absence, nature, severity and extent of adhesions correlated with demographic and patient reported clinical characteristics of women presenting with CPP. Women undergoing a laparoscopy for the investigation of chronic pelvic pain were recruited prospectively; their pain and phenotypic characteristics were entered into a hierarchical cluster analysis. The groups with differing baseline clinical and operative characteristics in terms of adhesions involvement were analyzed. Sixty two women were recruited where 37 had adhesions. A low correlation was found between women's reported current pain scores and that of most severe (r = 0.34) or average pain experienced (r = 0.44) in the last 6 months. Three main groups of women with CPP were identified: Cluster 1 (n = 35) had moderate severity of pain, with poor average and present pain intensity; Cluster 2 (n = 14) had a long duration of symptoms/diagnosis, the worst current pain and worst physical, emotional and social functions; Cluster 3 (n = 11) had the shortest duration of pain and showed the best evidence of coping with low (good) physical, social and emotional scores. This cluster also had the highest proportion of women with adhesions (82%) compared to 51% in Cluster 1 and 71% in Cluster 2. In this study, we found that there is little or no correlation between patient-reported pain, physical, emotional and functional characteristics scores with the presence or absence of intra-abdominal/pelvic adhesions found during investigative laparoscopy. Most women who had adhesions had the lowest reported current pain scores.

Yost, Gardner; Bhat, Geetha; Mahoney, Edward; Tatooles, Antone

Despite the high prevalence of depression and anxiety in patients with advanced heart failure, the effects of left ventricular assist device (LVAD) implantation on these critically important aspects of mental health are not well understood. We sought to assess changes in depression and anxiety following LVAD implantation. The Beck Depression Inventory-II (BDI-II) and Beck Anxiety Inventory (BAI) were administered to 54 patients by a clinical psychologist at a mean of 12 days before LVAD implantation and 251 days after implantation. Patient demographics and clinical data were collected concurrently to psychologic testing. Changes in BDI-II, BAI, and clinical markers of heart failure were assessed using paired t-tests. A p < 0.05 was considered significant. The average age of the group was 56.63 years with a mean ejection fraction 20.8%. Before implantation, mean BAI and BDI scores indicated mild depression and anxiety. Following LVAD implantation, average scores for both BDI-II and BAI decreased significantly, indicating minimal depression and anxiety (12.6-8.54, p = 0.001 and 12.06-6.6, p < 0.001, respectively). Mean scores were significantly lowered in 11 and 8 of the 21 subdomains tested by the BAI and BDI, respectively. Significant improvements were noted in post-LVAD B-type natriuretic peptide, serum sodium, and blood urea nitrogen. Depression and anxiety scores improved significantly after LVAD implantation. Factors contributing to changes in depression and anxiety after LVAD could be related to the improvement in acute heart failure symptoms, functional capacity, and quality of life. Prospective studies with larger sample sizes are warranted. Copyright © 2017 The Academy of Psychosomatic Medicine. Published by Elsevier Inc. All rights reserved.

To evaluate the impact of the intrauterine device (IUD) insertion on the mental state of women. From Jan. 2009 to Jun. 2010, a multi-center clinical observational study was performed. Totally 641 women were selected in the six provinces' 18 family planning service stations and hospitals for IUD insertion surgery study. Analysis of the change of women's mental state which was evaluated by symptom checklist-90 (SCL-90) scale before and after IUD insertion surgery. Before and after IUD insertion surgery, 10 factors' scores in SCL-90 of the observed objects were between 1.1 to 1.2, total scores were 107±27 and 105±25, respectively. Before and after surgery, total average score both were 1.2, the average score of positive items both were 2.1. The difference of the above results were not statistically significance (all P>0.05). Preoperative and postoperative, the rate of positive items was 9.2%-19.6% and 7.7%-17.6%, respectively.In addition to anxiety and fear, the rate of other factors' positive items postoperative was significantly lower than those in the preoperative (all P<0.05). The incidence of the observed objects postoperative of each factor score, "deteriorated" was in the range of 4.9% to 23.0%, "improved" was in the range of 26.3%-50.1%. The incidence of total scores, "deterioration" was 28.8% (166/575), "improved" was 45.6% (262/575). The incidence of the average score of positive items, "deterioration" was 3.7% (21/575), "improved" was 52.3% (301/575). Logistic analysis showed that, in addition to unit level, there were no other significant influencing factors for women' mental state of postoperative (all P>0.05). IUD insertion surgery has no adverse effect on women's mental state.

Introduction Internal medicine (IM) interns start continuity clinic with variable ambulatory training. Multiple other specialties have utilized a boot camp style curriculum to improve surgical and procedural skills, but boot camps have not been used to improve interns’ ambulatory knowledge and confidence. The authors implemented and assessed the impact of an intern ambulatory boot camp pilot on primary care knowledge, confidence, and curricular satisfaction. Methods During July 2014, IM interns attended ambulatory boot camp. It included clinically focused case-based didactic sessions on common ambulatory topics as well as orientation to the clinic and electronic medical records. Interns anonymously completed a 15-question pre-test on topics covered in the boot camp as well as an identical post-test after the boot camp. The interns were surveyed regarding their confidence and satisfaction. Results Thirty-eight interns participated in the boot camp. Prior to the boot camp, few interns reported confidence managing common outpatient conditions. The average pre-test knowledge score was 46.3%. The average post-test knowledge score significantly improved to 76.1% (p<0.001). All interns reported that the boot camp was good preparation for clinics and 97% felt that the boot camp boosted their confidence. Conclusions The ambulatory boot camp pilot improved primary care knowledge, and interns thought it was good preparation for clinic. The ambulatory boot camp was well received and may be an effective way to improve the preparation of interns for primary care clinic. Further assessment of clinical performance and expansion to other programs and specialties should be considered. PMID:26609962

Are Examiners' Judgments in OSCE-Style Assessments Influenced by Contrast Effects?

PubMed

Yeates, Peter; Moreau, Marc; Eva, Kevin

2015-07-01

Laboratory studies have shown that performance assessment judgments can be biased by "contrast effects." Assessors' scores become more positive, for example, when the assessed performance is preceded by relatively weak candidates. The authors queried whether this effect occurs in real, high-stakes performance assessments despite increased formality and behavioral descriptors. Data were obtained for the 2011 United Kingdom Foundational Programme clinical assessment and the 2008 University of Alberta Multiple Mini Interview. Candidate scores were compared with scores for immediately preceding candidates and progressively distant candidates. In addition, average scores for the preceding three candidates were calculated. Relationships between these variables were examined using linear regression. Negative relationships were observed between index scores and both immediately preceding and recent scores for all exam formats. Relationships were greater between index scores and the average of the three preceding scores. These effects persisted even when examiners had judged several performances, explaining up to 11% of observed variance on some occasions. These findings suggest that contrast effects do influence examiner judgments in high-stakes performance-based assessments. Although the observed effect was smaller than observed in experimentally controlled laboratory studies, this is to be expected given that real-world data lessen the strength of the intervention by virtue of less distinct differences between candidates. Although it is possible that the format of circuital exams reduces examiners' susceptibility to these influences, the finding of a persistent effect after examiners had judged several candidates suggests that the potential influence on candidate scores should not be ignored.

Recently, the efficacy of autologous plasma filler for the reduction of facial wrinkles has been demonstrated. The aim of our study is to validate the efficacy and safety of autologous plasma filler in treating nasolabial fold wrinkles. Twenty Korean patients with moderate-to-severe nasolabial fold wrinkles were enrolled. The patients were treated with one session of autologous plasma filler. The wrinkle improvement effects were evaluated at 1-week, 4-week, 8-week, and 12-week after the treatment. Three assessment methods were applied. First, two independent dermatologists assessed cosmetic results using a 5-point wrinkle assessment scale. Second, global aesthetic improvement score was used for assessment of the final cosmetic results. Third, patient satisfaction was surveyed. Also, the adverse effects associated to treatment were observed. Mean age of the patients was 44.5 years. The average 5-point wrinkle assessment scale score was significantly improved at 1, 4, 8, and 12 weeks after treatment, comparing to before treatment (p < 0.01). The patients' average global aesthetic improvement score also indicated better cosmetic outcomes. The clinical improvement with sufficient patients' satisfaction and no significant adverse events demonstrated that novel autologous plasma filler could be considered as efficient and safety treatment option for nasolabial fold wrinkles.

Incentives to improve performance are emerging as revenue or financial penalties are linked to the measured quality of service provided. The HCA "Getting to Green" program was designed to rapidly increase core measure performance scores. Program components included (1) the "business case for quality"-increased awareness of how quality drives financial performance; (2) continuous communication of clinical and financial performance data; and (3) evidence-based clinical protocols, incentives, and tools for process improvement. Improvement was measured by comparing systemwide rates of adherence to national quality measures for heart failure (HF), acute myocardial infarction (AMI), pneumonia (PN), and surgical care (SCIP) to rates from all facilities reporting to the Centers for Medicare and Medicaid Services (CMS). As of the second quarter of 2011, 70% of HCA total measure set composite scores were at or above the 90th percentile of CMS scores. A test of differences in regression coefficients between the CMS national average and the HCA average revealed significant differences for AMI (p = .001), HF (p = .012), PN (p < .001), and SCIP (p = .015). This program demonstrated that presentation of the financial implications of quality, transparency in performance data, and clearly defined goals could cultivate the desire to use improvement tools and resources to raise performance. © 2012 National Association for Healthcare Quality.

Melasma is an acquired hyperpigmentary disorder commonly seen in Orientals. Recently it has been demonstrated that tretinoin (all-trans-retinoic acid) can produce significant clinical improvement of melasma. However, moderate cutaneous side effects (retinoid dermatitis) occurred in a number of patients. To investigate the efficacy of topical 0.05 per cent isotretinoin gel (Isotrex) in the treatment of melasma in Thai patients. Thirty patients with moderate to severe melasma entered a 40-week, randomized, vehicle-controlled clinical trial in which they applied either 0.05 per cent isotretinoin gel, or its vehicle base together with a broad spectrum sunscreen (SPF 28) daily to the entire face. They were evaluated clinically (using Melasma Area and Severity Index), and colorimetrically (using our Melasma Area and Melanin Index). After 40 weeks, the average MASI and MAMI scores of the isotretinoin-treated group decreased by 68.2 per cent and 47 per cent respectively, while the corresponding control scores declined 60 per cent and 34 per cent. There was no statistically significant difference between the isotretinoin and vehicle groups. When the MASI and MAMI scores of each visit were compared to their baseline data, a statistically significant reduction of the score was first noted at weeks 4 and 12 respectively. Lightening of melasma, as determined clinically (MASI score), correlated well with pigmentation measurements (MAMI score). Side effects were limited to a mild transient "retinoid dermatitis" occurring in 27 per cent of isotretinoin-treated patients. Daily use of broad spectrum sunscreen has a significant lightening effect on melasma in Thai patients. However, there was no statistically significant difference between the isotretinoin and vehicle-treated group.

To compare clinical effects of core decompression with stem cell transplantation and tantalum rod implanting in treating stage II non-traumatic osteonecrosis of femoral head. From March 2012 to September 2012, 45 patients(55 hips)with stage ARCO II non-traumatic osteonecrosis of femoral head were treated and divided into core decompression with stem cell transplantation group(group A) and tantalum rod implanting group(group B) according to number table. In group A, there were 23 cases(28 hips) , including 12 males and 11 females aged from 23 to 51 years old with an average of (36.87±9.52) years, the courses of disease ranged from 2 to 28 months with an average of (17.13±7.74) months, preoperative Harris score was for 35 to 70 with an average of(54.74±11.81), treated with core decompression with stem cell transplantation. In group B, there were 22 cases(27 hips), including 11 males and 11 females aged from 26 to 46 years old with an average of (35.59±7.39) years, the courses of disease ranged from 3 to 26 months with an average of(16.00±7.46) months, preoperative Harris score was for 35 to 76 with an average of (57.18±12.95), treated with core tantalum rod implanting. Operative time, blood loss, hospital stays, hospitalization expenses were observed and compared after treatment between two groups, the clinical effects were evaluated according to Harris criteria. All patients were followed up from 6 to 12 months with an average of 10.8 months. There were significant difference in hospitalization expenses between two groups( P <0.05), while there was no significant statistical difference in blood loss and hospital stay ( P >0.05). At the final following-up, Harris score in group A was(83.04±8.97), 6 cases obtained excellent results, 14 good, 2 good and 1 poor;while Harris score in group A was(84.41±9.94), and 9 cases obtained excellent results, 9 good, 3 good and 1 poor; there was no statistical meaning differences between two groups( P >0.05). Core decompression with stem cell transplantation and tantalum rod implanting could both improve function of hip joint, while core decompression with stem cell transplantation had advantages of shorter operation time, less cost, and higher potency ratio. It is suitable for stage ARCO II non-traumatic femoral head necrosis.

The purposes of this study were to determine clinical presentations and surgical outcomes of perforated peptic ulcer (PPU), and to evaluate the accuracy of the Boey scoring system in predicting mortality and morbidity. We carried out a retrospective study of patients undergoing emergency surgery for PPU between 2001 and 2006 in a university hospital. Clinical presentations and surgical outcomes were analyzed. Adjusted odds ratio (OR) of each Boey score on morbidity and mortality rate was compared with zero risk score. Receiver-operating characteristic curve analysis was used to compare the predictive ability between Boey score, American Society of Anesthesiologists (ASA) classification, and Mannheim Peritonitis Index (MPI). The study included 152 patients with average age of 52 years (range: 15-88 years), and 78% were male. The most common site of PPU was the prepyloric region (74%). Primary closure and omental graft was the most common procedure performed. Overall mortality rate was 9% and the complication rate was 30%. The mortality rate increased progressively with increasing numbers of the Boey score: 1%, 8% (OR=2.4), 33% (OR=3.5), and 38% (OR=7.7) for 0, 1, 2, and 3 scores, respectively (p<0.001). The morbidity rates for 0, 1, 2, and 3 Boey scores were 11%, 47% (OR=2.9), 75% (OR=4.3), and 77% (OR=4.9), respectively (p<0.001). Boey score and ASA classification appeared to be better than MPI for predicting the poor surgical outcomes. Perforated peptic ulcer is associated with high rates of mortality and morbidity. The Boey risk score serves as a simple and precise predictor for postoperative mortality and morbidity.

The aim of this study was to determine the presence of Asian dust particles (ADP) in patients suffering from conjunctivitis and its correlation with clinical scores for conjunctivitis. Forty-five patients from the Fukuoka area who were newly diagnosed acute conjunctivitis were selected. The degrees of inflammatory reaction, itchy sensation, hyperemia, eye discharge, and foreign body sensation were clinically recorded and scored. Eyes were washed with physiological solution. Solid particles collected from the washing solution were observed using a scanning electron microscope. Of the 45 samples, 44 were positive for the elements silicon (Si) and aluminum (Al), which are components of ambient Asian dust. Higher conjunctivitis scores were found in the subgroup in which the Asian dust/whole particle ratio was greater than average. This is the first apparent report on the correlation between amount of ADP exposure at the ocular surface and severity of ocular symptoms.

This study investigated long-term speech and language outcomes in 51 prelingually deaf children, adolescents, and young adults who received cochlear implants (CIs) prior to 7 years of age and used their implants for at least 7 years. Average speech perception scores were similar to those found in prior research with other samples of experienced CI users. Mean language test scores were lower than norm-referenced scores from nationally representative normal-hearing, typically-developing samples, although a majority of the CI users scored within one standard deviation of the normative mean or higher on the Peabody Picture Vocabulary Test, Fourth Edition (63%) and Clinical Evaluation of Language Fundamentals, Fourth Edition (69%). Speech perception scores were negatively associated with a meningitic etiology of hearing loss, older age at implantation, poorer pre-implant unaided pure tone average thresholds, lower family income, and the use of Total Communication. Users of CIs for 15 years or more were more likely to have these characteristics and were more likely to score lower on measures of speech perception compared to users of CIs for 14 years or less. The aggregation of these risk factors in the > 15 years of CI use subgroup accounts for their lower speech perception scores and may stem from more conservative CI candidacy criteria in use at the beginning of pediatric cochlear implantation.

Background: Fat embolism syndrome (FES) is a constellation of symptoms and signs subsequent to orthopedic trauma. Materials and Methods: The clinical profile of FES in the trauma population was studied over 2 years and 8 months. Results: The incidence of FES among all patients with long bone and pelvic fractures was 0.7% (12). The mean injury severity score was 10.37 (SD 1.69) (range 9-14). The diagnosis of FES was made by clinical and laboratory criteria. Hypoxia was the commonest presentation (92%). The average days of onset of symptoms were 3.5 (SD1.29) days. Management included ventilator support in 75%, average ventilator days being 7.8 (SD 4.08) days. The average ICU stay and hospital stay were 9.1 days and 29.7 days, respectively. A mortality of 8.3% (1) was observed. Conclusion: Fat embolism remains a diagnosis of exclusion and is a clinical dilemma. Clinically apparent FES is unusual and needs high index of suspicion, especially in long bone and pelvic fractures. PMID:21887021

To determine the psychometric characteristics of diagnostic justification scores based on the patient note format of the United States Medical Licensing Examination Step 2 Clinical Skills exam, which requires students to document history and physical findings, differential diagnoses, diagnostic justification, and plan for immediate workup. End-of-third-year medical students at one institution wrote notes for five standardized patient cases in May 2013 (n = 180) and 2014 (n = 177). Each case was scored using a four-point rubric to rate each of the four note components. Descriptive statistics and item analyses were computed and a generalizability study done. Across cases, 10% to 48% provided no diagnostic justification or had several missing or incorrect links between history and physical findings and diagnoses. The average intercase correlation for justification scores ranged from 0.06 to 0.16; internal consistency reliability of justification scores (coefficient alpha across cases) was 0.38. Overall, justification scores had the highest mean item discrimination across cases. The generalizability study showed that person-case interaction (12%) and task-case interaction (13%) had the largest variance components, indicating substantial case specificity. The diagnostic justification task provides unique information about student achievement and curricular gaps. Students struggled to correctly justify their diagnoses; performance was highly case specific. Diagnostic justification was the most discriminating element of the patient note and had the greatest variability in student performance across cases. The curriculum should provide a wide range of clinical cases and emphasize recognition and interpretation of clinically discriminating findings to promote the development of clinical reasoning skills.

Prospective cohort study. To study clinicoradiological parameters of zero-profile cage screw used for anterior cervical discectomy and fusion (ACDF). Radiological parameters of various implants used for ACDF are available, but those for zero-profile cage are sparse. Patients with unilateral intractable brachialgia due to single-level cervical disc prolapse between April 1, 2011 and March 31, 2014 were included. Clinical assessment included arm and neck pain using visual analogue score (VAS) and neck disability index (NDI) scores. Radiological assessment included motion segment height, adjacent disc height (upper and lower), segmental and cervical lordosis, implant subsidence, and pseudoarthrosis. Follow-ups were scheduled at 1, 3, 6, 12, and 24 months. Thirty-four patients (26 males, 8 females) aged 30-50 years (mean, 42.2) showed excellent clinical improvement based on VAS scores (7.4-0 for arm and 2.0-0.6 for neck pains). Postoperative disc height improved by 11.33% ( p <0.001), but at 2 years, the score deteriorated by 7.03% ( p <0.001). Difference in the adjacent segment disc height at 2 years was 0.08% ( p =0.8) in upper and 0.16% ( p <0.001) in lower disc spaces. Average segmental lordosis achieved was 5.59° ( p <0.001) from a preoperative kyphosis of 0.88°; at 2 years, an average loss of 7.05° ( p <0.001) occurred, resulting in an average segmental kyphosis of 1.38°. Cervical lordosis improved from 11.59° to 14.88° ( p =0.164), and at 2 years, it progressively improved to 22.59° ( p <0.001). Three patients showed bone formation and two mild protrusion of the implant at 2 years without pseudoarthrosis/implant failure. The zero-profile cage screw device provides good fusion and cervical lordosis but is incapable of maintaining the segmental lordosis achieved up to a 2-year follow-up. We also recommend caution when using it in patients with small vertebrae.

To assess the value of current selection criteria and additional factors as predictors of performance in an ophthalmology residency training program. A retrospective study. Data were collected from the files of 166 residents who were collectively trained in an ophthalmology residency program from 2000 to 2013. The program's selection criteria included medical school grade point average (GPA), Saudi licensing examination (SLE) score, multiple-choice question ophthalmology selection (MCQ) examination score, and interview mark. Indicators of performance included average scores in the promotion examination for 4 years of training (average R), King Saud University fellowship examination (KSU) score, and Saudi Board in Ophthalmology examination (SBO) score. An average of KSU and SBO scores was also used as a performance indicator. Times of program completion and average performance score across all years in the residency program were used as second-level indicators of performance. There were strong correlations between the MCQ examination score and each training performance indicator (average R, KSU score, SBO score, and average of KSU and SBO scores; p = 0.002, 0.008, 0.05, and 0.002, respectively). The interview mark correlated well with average R (p = 0.001) but not with other indicators. The MCQ examination score and the interview mark were the only predictors of second-level indicators of performance (p = 0.009 and 0.029, respectively). The MCQ examination score and interview mark were the 2 best predictors of performance as an ophthalmology resident. GPA and SLE score were poor predictors of performance.

The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears. 22 patients of arthroscopic single row repair (group I) and 25 patients who underwent double row repair (group II) from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES). In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method. Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

Objective The purpose of this study was to evaluate radiographic/clinical outcomes of adolescent idiopathic scoliosis (AIS) patients treated by a Korean neurosurgeon. Methods Ten AIS patients were treated by a single neurosurgeon between January 2011 and September 2013 utilizing segmental instrumentation with pedicle screws. Basic demographic information, curve pattern by Lenke classification, number of levels treated, amount of correction achieved, radiographic/clinical outcomes [by Scolisis Resarch Society (SRS-22r) questionnaire] and complications were evaluated to determine the surgical results. Pulmonary function test was utilized to assess forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) before and after surgery. Results The average percentage of correction of the major structural curve was 73.6% (ranged from 64% to 81.5%). Preoperative and final postoperative absolute FVC averaged 3.03 L and 3.76 L (0.73 L increase, p=0.046), and absolute FEV1 averaged 2.63 L and 3.49 L (0.86 L increase, p=0.021). Preoperative and final postoperative average self-image and function scores of SRS-22r were, 2.6±0.5, 3.3±0.1, 4.0±0.5, and 4.6±0.0, respectively. There was a significant improvement of the self-image and function scores of SRS-22r questionnaires before and after surgery (p<0.05). There was no case of neurological deficit, infection and revision for screw malposition. One patient underwent a fusion extension surgery for shoulder asymmetry. Conclusion Radiographic/clinical outcomes of AIS patients treated by a Korean neurosurgeon were acceptable. Fundamental understanding of pediatric spinal deformity is essential for the practice of AIS surgery. PMID:26279813

2007-01-01

Idiopathic environmental intolerance (IEI) is a descriptor for nonspecific complaints that are attributed to environmental exposure. The Minnesota Multiphasic Personality Inventory 2 (MMPI-2) was administered to 50 female and 20 male personal injury litigants alleging IEI. The validity scales indicated no overreporting of psychopathology. Half of the cases had elevated scores on validity scales suggesting defensiveness, and a large number had elevations on Fake Bad Scale (FBS) suggesting overreporting of unauthenticated symptoms. The average T-score profile for females was defined by the two-point code type 3-1 (Hysteria-Hypochondriasis), and the average T-score profile for males was defined by the three-point code type 3-1-2 (Hysteria, Hypochondriasis-Depression). On the content scales, Health Concerns (HEA) scale was significantly elevated. Idiopathic environmental intolerance litigants (a) are more defensive about expressing psychopathology, (b) express distress through somatization, (c) use a self-serving misrepresentation of exaggerated health concerns, and (d) may exaggerate unauthenticated symptoms suggesting malingering.

Parkinson Disease (PD) is a late onset disorder with age-dependent penetrance that may confound genetic studies since affected individuals may not demonstrate clinical manifestations at the time of evaluation. The use of endophenotypes, biologic surrogates for clinical disease diagnoses, may permit more accurate classification of at-risk subjects. Positron emission tomography (PET) measurements of 6-[18F]fluorodopa ([18F]FDOPA) uptake indicate nigrostriatal neuronal integrity and may provide a useful endophenotype for PD linkage studies. We performed [18F]FDOPA PET in 11 members of a large, multi-incident Amish family with PD, 24 normals and 48 people with clinically definite idiopathic PD (PD controls). Clinical diagnoses in the Amish were clinically definite PD in four, clinically probable in one, clinically possible in five, and normal in one. Abnormal [18F]FDOPA posterior putamen uptake was defined as less than three standard deviations below the normal mean. The criteria were applied to the Amish sample to determine a PET endophenotype for each. We performed genetic simulations using SLINK to model the effect phenoconversion with the PET endophenotype had on logarithm of odds (LOD) scores. PET endophenotype confirmed the status of two clinically definite subjects. Two clinically definite Amish PD subjects had normal PETs. Two possible PD were converted to “PET definite PD”. The remainder had normal PETs. The average maximum LOD score with the pre-PET was 6.14±0.84. Simulating phenoconversion of subjects with unknown phenotypes increased the LOD score to 7.36±1.23. The [18F]FDOPA PET endophenotype permits phenoconversion in multi-incident PD families and may increase LOD score accuracy and power of an informative pedigree. PMID:16528749

The current authors present and evaluate a technique for reconstructing proximal humeral defects that result after resection of malignant bone tumors. Sixteen patients were included in this study with an average followup of 3 years (range, 12-76 months). Twelve patients had intraarticular resections, two had extraarticular resections, and two had intercalary resections. Reconstruction was done at the lateral border of the scapula (based on the circumflex scapular vessels) that was osteotomized and mobilized to bridge the resultant defect. Shoulder arthrodesis was done in 14 patients and the shoulder was spared in the two patients who had intercalary resections. Function was evaluated according to the Musculoskeletal Tumor Society scoring system. The average time for union of the graft proximally and distally was 6 months after which the graft started to hypertrophy. The average functional score was 22.5 points (75%) with a minimum score of 18 points (60%) and a maximum score of 27 points (90%). Nonunion of the distal host-graft junction occurred in two patients; both patients required iliac crest bone grafting and both achieved clinical and radiographic union without additional intervention. In three patients, the proximal fixation became loose but had no effect on function. The authors conclude that this technique is inexpensive, effective, and a durable reconstructive option for proximal humeral defects that are less than 15 cm. It has a predictable functional outcome (60%-90%) that is comparable with other reconstructive options.

It was to assess the quality of life (QOL) of HIV-infected pregnant women using the HIV/AIDS - Targeted Quality of Life (HAT-QoL) questionnaire. A descriptive study of 60 pregnant women attended at the Multidisciplinary Nucleus of Infectious Diseases During Pregnancy (NUPAIG) - UNIFESP/EPM and in the referral network of the Municipal Office of São Paulo, conducted from February 2011 to October 2012. Sociodemographic and clinical variables were collected from 60 HIV-infected pregnant women who answered the HAT-QoL questionnaire, which included 34 questions about quality of life. The average age was 30 years and the average period of HIV infection was 5.7 years. Only 8.3% of patients had a CD4 cell score of ≤200 cells/mm³ and 45% showed undetectable viral load. The average domain scores ranged from 47.5 to 83.7. The domains with the lowest scores were financial concerns and concerns about secrecy. The domains with the highest scores and lower impact on quality of life were concerns about medication and confidence in the professional. In this initial study with 60 pregnant women, we concluded that the HAT-QOL can contribute to the assessment of quality of life in the population of HIV-infected pregnant women in Brazil.

The Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow questionnaire has been shown by previous studies to be more sensitive than other validated subjective measurement tools in the detection of upper extremity dysfunction in overhead-throwing athletes. The primary objective was to establish normative data for KJOC scores in professional baseball players in the United States. The secondary objectives were to evaluate the effect of player age, playing position, professional competition level, history of injury, history of surgery, and time point of administration on the KJOC score. Cross-sectional study; Level of evidence, 3. From 2011 to 2012, a total of 203 major league and minor league baseball players within the Houston Astros professional baseball organization completed the KJOC questionnaire. The questionnaire was administered at 3 time points: spring training 2011, end of season 2011, and spring training 2012. The KJOC scores were analyzed for significant differences based on player age, injury history, surgery history, fielding position, competition level, self-reported playing status, and time point of KJOC administration. The average KJOC score among healthy players with no history of injury was 97.1 for major league players and 96.8 for minor league players. The time point of administration did not significantly affect the final KJOC score (P = .224), and KJOC outcomes did not vary with player age (r = -0.012; P = .867). Significantly lower average KJOC scores were reported by players with a history of upper extremity injury (86.7; P < .001) and upper extremity surgery (75.4; P < .0001). The KJOC results did vary with playing position (P = .0313), with the lowest average scores being reported by pitchers (90.9) and infielders (91.3). This study establishes a quantitative baseline for the future evaluation of professional baseball players with the KJOC score. Age and time of administration had no significant effect on the outcome of the KJOC score. Missed practices or games within the previous year because of injury were the most significant demographic predictors of lower KJOC scores. The KJOC score was shown to be a sensitive measurement tool for detecting subtle changes in the upper extremity performance of the professional baseball population studied.

Weight loss is a common symptom of Parkinson's disease and is associated with impaired quality of life. Predictors of weight loss have not been studied in large clinical cohorts. We previously observed an association between change in body mass index and change in Unified Parkinson's Disease Rating Scale (UPDRS) motor and total scores. In this study, we performed a secondary analysis of longitudinal data (1-6 years) from 1619 participants in the NINDS Exploratory Trials in PD Long-term Study-1 (NET-PD LS1) to explore predictors of weight loss in a large prospective clinical trial cohort of early treated Parkinson's disease. The NET-PD LS1 study was a double-blind randomized placebo controlled clinical trial of creatine monohydrate 10 gm/day in early treated PD (within 5 years of diagnosis and within 2 years of starting dopaminergic medications). Linear mixed models were used to estimate the effect of baseline clinical covariates on weight change over time. On average, participants lost only 0.6 kg per year. Higher age, baseline weight, female gender, higher baseline UPDRS scores, greater postural instability, difficulty eating and drinking, lower cognitive scores and baseline levodopa use (compared to dopamine agonists) were all associated with weight loss. Surprisingly baseline difficulty swallowing, dyskinesia, depression, intestinal hypomotility (constipation) and self-reported nausea/vomiting/anorexia were not significantly associated with weight loss in this cohort of early treated Parkinson's disease patients. On average, participants with Parkinson's disease experience little weight loss during the first 1-6 years after starting dopaminergic replacement therapy, however levodopa use and postural instability were both predictors of early weight loss.

Constrained implants are frequently required in revision total knee arthroplasty (TKA) and are associated with an increase in aseptic component loosening and damage or wear to the constraining mechanisms, compared with primary TKA. The purpose of the following study was to evaluate the midterm clinical and radiographic results including the incidence of bearing complications in a group of patients undergoing revision TKA using mobile-bearing revision TKA implants. We retrospectively reviewed 316 consecutive mobile-bearing revision TKAs performed at 2 centers between 2006 and 2010. There were 183 women and 133 men with a mean age of 66 years. The patients were evaluated clinically using the Knee Society scores. A radiographic analysis was performed. Bearing specific complications (ie, instability or dislocation) were recorded. Patients were followed-up for a minimum of 24 months and a median of 59.88 months (range 24-121.2). The average Knee Society knee score and function scores increased from 40.8 and 47.9 points preoperatively to 80 points and 70.3 points, respectively (P < .01). The average knee flexion improved from 105.6° preoperatively to 117.4° postoperatively (P < .01). Eight patients required subsequent implant revision. No cases of bearing complications were observed. Revision TKA using mobile-bearing revision components demonstrated favorable midterm clinical and radiographic results with no occurrence of bearing instability or dislocation. Longer follow-up is required to evaluate for potential advantages of mobile-bearings over fixed-bearing revision components in terms of polyethylene wear reduction, reduced stress transmission across fixation interfaces, and reduced stress on the polyethylene post.

Medical schools employ a variety of preadmission measures to select students most likely to succeed in the program. The Medical College Admission Test (MCAT) and the undergraduate college grade point average (uGPA) are two academic measures typically used to select students in medical school. The assumption that presently used preadmission measures can predict clinical skill performance on a medical licensure examination was evaluated within a validity argument framework (Kane 1992). A hierarchical generalized linear model tested relationships between the log-odds of failing a high-stakes medical licensure performance examination and matriculant academic and non-academic preadmission measures, controlling for student-and school-variables. Data includes 3,189 matriculants from 22 osteopathic medical schools tested in 2009-2010. Unconditional unit-specific model expected average log-odds of failing the examination across medical schools is -3.05 (se = 0.11) or 5%. Student-level estimated coefficients for MCAT Verbal Reasoning scores (0.03), Physical Sciences scores (0.05), Biological Sciences scores (0.04), uGPA(science) (0.07), and uGPA(non-science) (0.26) lacked association with the log-odds of failing the COMLEX-USA Level 2-PE, controlling for all other predictors in the model. Evidence from this study shows that present preadmission measures of academic ability are not related to later clinical skill performance. Given that clinical skill performance is an important part of medical practice, selection measures should be developed to identify students who will be successful in communication and be able to demonstrate the ability to systematically collect a medical history, perform a physical examination, and synthesize this information to diagnose and manage patient conditions.

Purpose To assess clinical and functional results of chemoradiotherapy for oropharyngeal cancer (OPC), utilizing intensity-modulated radiotherapy (IMRT) to spare the important swallowing structures to reduce post-therapy dysphagia. Patients and Methods This was a prospective study of weekly chemotherapy (carboplatin dosed at one times the area under the curve [AUC, AUC 1] and paclitaxel 30 mg/m2) concurrent with IMRT aiming to spare noninvolved parts of the swallowing structures: pharyngeal constrictors, glottic and supraglottic larynx, and esophagus as well as the oral cavity and major salivary glands. Swallowing was assessed by patient-reported Swallowing and Eating Domain scores, observer-rated scores, and videofluoroscopy (VF) before therapy and periodically after therapy through 2 years. Results Overall, 73 patients with stages III to IV OPC participated. At a median follow-up of 36 months, 3-year disease-free and locoregional recurrence-free survivals were 88% and 96%, respectively. All measures of dysphagia worsened soon after therapy; observer-rated and patient-reported scores recovered over time, but VF scores did not. At 1 year after therapy, observer-rated dysphagia was absent or minimal (scores 0 to 1) in all patients except four: one who was feeding-tube dependent and three who required soft diet. From pretherapy to 12 months post-therapy, the Swallowing and Eating Domain scores worsened on average (± standard deviation) by 10 ± 21 and 13 ± 19, respectively (on scales of 0 to 100), and VF scores (on scale of 1 to 7) worsened from 2.9 ± 1.5 (mild dysphagia) to 4.1 ± 0.9 (mild/moderate dysphagia). Conclusion Chemoradiotherapy with IMRT aiming to reduce dysphagia can be performed safely for OPC and has high locoregional tumor control rates. On average, long-term patient-reported, observer-rated, and objective measures of swallowing were only slightly worse than pretherapy measures, representing potential improvement compared with previous studies.

BACKGROUND Thymectomy has been a mainstay in the treatment of myasthenia gravis, but there is no conclusive evidence of its benefit. We conducted a multicenter, randomized trial comparing thymectomy plus prednisone with prednisone alone. METHODS We compared extended transsternal thymectomy plus alternate-day prednisone with alternate-day prednisone alone. Patients 18 to 65 years of age who had generalized nonthymomatous myasthenia gravis with a disease duration of less than 5 years were included if they had Myasthenia Gravis Foundation of America clinical class II to IV disease (on a scale from I to V, with higher classes indicating more severe disease) and elevated circulating concentrations of acetylcholine-receptor antibody. The primary outcomes were the time-weighted average Quantitative Myasthenia Gravis score (on a scale from 0 to 39, with higher scores indicating more severe disease) over a 3-year period, as assessed by means of blinded rating, and the time-weighted average required dose of prednisone over a 3-year period. RESULTS A total of 126 patients underwent randomization between 2006 and 2012 at 36 sites. Patients who underwent thymectomy had a lower time-weighted average Quantitative Myasthenia Gravis score over a 3-year period than those who received prednisone alone (6.15 vs. 8.99, P<0.001); patients in the thymectomy group also had a lower average requirement for alternate-day prednisone (44 mg vs. 60 mg, P<0.001). Fewer patients in the thymectomy group than in the prednisone-only group required immunosuppression with azathioprine (17% vs. 48%, P<0.001) or were hospitalized for exacerbations (9% vs. 37%, P<0.001). The number of patients with treatment-associated complications did not differ significantly between groups (P=0.73), but patients in the thymectomy group had fewer treatment-associated symptoms related to immunosuppressive medications (P<0.001) and lower distress levels related to symptoms (P=0.003). CONCLUSIONS Thymectomy improved clinical outcomes over a 3-year period in patients with nonthymomatous myasthenia gravis.

Fracture reduction and primary ankle arthrodesis: a reliable approach for severely comminuted tibial pilon fracture.

PubMed

Beaman, Douglas N; Gellman, Richard

2014-12-01

Posttraumatic arthritis and prolonged recovery are typical after a severely comminuted tibial pilon fracture, and ankle arthrodesis is a common salvage procedure. However, few reports discuss the option of immediate arthrodesis, which may be a potentially viable approach to accelerate overall recovery in patients with severe fracture patterns. (1) How long does it take the fracture to heal and the arthrodesis to fuse when primary ankle arthrodesis is a component of initial fracture management? (2) How do these patients fare clinically in terms of modified American Orthopaedic Foot and Ankle Society (AOFAS) scores and activity levels after this treatment? (3) Does primary ankle arthrodesis heal in an acceptable position when anterior ankle arthrodesis plates are used? During a 2-year period, we performed open fracture reduction and internal fixation in 63 patients. Eleven patients (12 ankles) with severely comminuted high-energy tibial pilon fractures were retrospectively reviewed after surgical treatment with primary ankle arthrodesis and fracture reduction. Average patient age was 58 years, and minimum followup was 6 months (average, 14 months; range, 6-22 months). Anatomically designed anterior ankle arthrodesis plates were used in 10 ankles. Ring external fixation was used in nine ankles with concomitant tibia fracture or in instances requiring additional fixation. Clinical evaluation included chart review, interview, the AOFAS ankle-hindfoot score, and radiographic evaluation. All of the ankle arthrodeses healed at an average of 4.4 months (range, 3-5 months). One patient had a nonunion at the metaphyseal fracture, which healed with revision surgery. The average AOFAS ankle-hindfoot score was 83 with 88% having an excellent or good result. Radiographic and clinical analysis confirmed a plantigrade foot without malalignment. No patients required revision surgery for malunion. Primary ankle arthrodesis combined with fracture reduction for the severely comminuted tibial pilon fracture reliably healed and restored acceptable function in this highly selective patient group. Ring external fixation may be a useful adjunct to internal fixation, and this concept should be further studied. Level IV, therapeutic study.

Oral and pharyngeal cancers are responsible for over 7600 deaths each year in the United States. Given the significance of the disease and the fact that many individuals increasingly rely on health information on the Internet, it is important that patients and others can access clear and accurate oral cancer information on the Web. The objective of this study was threefold: (a) develop an initial method to evaluate surface and content quality of selected English- and Spanish-language oral cancer Web sites; (b) conduct a pilot evaluation; and (c) discuss implications of our findings for dental public health. We developed a search strategy to find oral cancer sites frequented by the public using Medline Plus, Google, and Yahoo in English and Spanish. We adapted the Information Quality Tool (IQT) to perform a surface evaluation and developed a novel tool to evaluate site content for 24 sites each in English and Spanish. English-language sites had an average IQT score of 76.6 (out of 100) and an average content score of 52.1 (out of 100). Spanish-language sites had an average IQT score of 50.3 and an average content score of 25.6. The study produced a quality assessment of oral cancer Web sites useful for clinicians and patients. Sites provided more information on clinical presentation, and etiology, and risk factors, than other aspects of oral cancer. The surface and quality of Spanish-language sites was low, possibly putting Hispanic populations at a disadvantage regarding oral cancer information on the Web.

1995-10-01

Environmental and genetic factors affecting somatic cell scores, clinical mastitis, and IMI by minor and major pathogens were studied on 137 periparturient Holstein cows selected for milk production. Environmental effects were obtained by generalized least squares and logistic regression. Genetic parameters were from BLUP and threshold animal models. Lactation number affected the number of quarters with clinical mastitis and the number of quarters infected with minor pathogens. The DIM affected somatic cell score and number of quarters infected with major pathogens. Heritabilities for all mastitis indicators averaged 10%, but differences occurred among the indicators. Correlations between breeding values of the number of quarters infected with minor pathogens and the number infected with major pathogens were antagonistic and statistically significant.

Studies have demonstrated the potential of platelet-rich plasma (PRP) to heal damaged tissue. To date, there are no published reports of clinical outcomes of partial ulnar collateral ligament (UCL) tears of the elbow treated with PRP. Platelet-rich plasma will promote the healing of partial UCL tears and allow a return to play. Case series; Level of evidence, 4. Thirty-four athletes with a partial-thickness UCL tear confirmed on magnetic resonance imaging were prospectively followed. All patients had failed at least 2 months of nonoperative treatment and an attempt to return to play. Baseline questionnaires, including the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow (KJOC) and Disabilities of the Arm, Shoulder and Hand (DASH) measures, were completed by each patient before injection. Baseline ultrasound measurement of the humeral-ulnar joint space was assessed with 10 lb of valgus stress on the elbow. Each patient received a single type 1A PRP injection at the UCL under ultrasound guidance. The same treating physician at a single institution performed all injections with the same PRP preparation used. Patients completed a course of guided physical therapy and were allowed to return to play based on their symptoms and physical examination findings. Outcome scores, including KJOC and DASH scores, were collected after return to play and were compared with baseline scores. Ultrasound measurements were collected at final follow-up and compared with preinjection values. At an average follow-up of 70 weeks (range, 11-117 weeks), 30 of 34 athletes (88%) had returned to the same level of play without any complaints. The average time to return to play was 12 weeks (range, 10-15 weeks). The average KJOC score improved from 46 to 93 (P < .0001). The average DASH score improved from 21 to 1 (P < .0001). The sports module of the DASH questionnaire improved from 69 to 3 (P < .0001). Medial elbow joint space opening with valgus stress decreased from 28 to 20 mm at final follow-up (P < .0001). The difference in medial elbow joint space opening (stressed vs nonstressed) decreased from 7 to 2.5 mm at final follow-up (P < .0001). One player had persistent UCL insufficiency and underwent ligament reconstruction at 31 weeks after injection. The results of this study indicate that PRP is an effective option to successfully treat partial UCL tears of the elbow in athletes.

Kinematic assessments are increasingly used as motor outcome measures during upper limb robot-assisted training, in addition to clinical scales. However, their relevance has not been evaluated much. Thirty-eight patients with severe sub-acute stroke (age 56 ± 17 [19-87] years; time since stroke, 55 ± 22 days) carried out 16 sessions (average 3/week, 35 ± 15 days) of upper limb robot-assisted training combined with standard therapy. Pre/post motor performance was evaluated using the Fugl-Meyer Assessment scale, Motor Status Scale (MSS) and kinematic measures. Motor outcomes were compared and relationships between clinical and kinematic outcomes were analyzed. All clinical and kinematic outcomes improved after training (p <  0.01). FM score increased from 17.7 ± 10.0 to 28.6 ± 15.4. All baseline kinematic measures were strongly correlated with clinical scores. Correlations between clinical and kinematic changes were moderate (r = -0.65 for change in FM Proximal score and change in accuracy measure). However, smoothness and accuracy indicators were shown to be responsive measures. This study demonstrated that baseline kinematic measures and their pre/post training changes were significantly correlated with clinical motor outcome measures. However, even if kinematic measures are valid for the evaluation of motor impairment we cannot propose to substitute common clinical measures of motor function which also evaluate functional abilities of the upper limb.

The relationships of students' preadmission academic variables, sex, undergraduate major, and undergraduate institution to academic performance in medical school have not been thoroughly examined. To determine the ability of students' preadmission academic variables to predict osteopathic medical school performance and whether students' sex, undergraduate major, or undergraduate institution influence osteopathic medical school performance. The study followed students who graduated from New York College of Osteopathic Medicine of New York Institute of Technology in Old Westbury between 2003 and 2006. Student preadmission data were Medical College Admission Test (MCAT) scores, undergraduate grade point averages (GPAs), sex, undergraduate major, and undergraduate institutional selectivity. Medical school performance variables were GPAs, clinical performance (ie, clinical subject examinations and clerkship evaluations), and scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Clinical Evaluation (CE). Data were analyzed with Pearson product moment correlation coefficients and multivariate linear regression analyses. Differences between student groups were compared with the independent-samples, 2-tailed t test. A total of 737 students were included. All preadmission academic variables, except nonscience undergraduate GPA, were statistically significant predictors of performance on COMLEX-USA Level 1, and all preadmission academic variables were statistically significant predictors of performance on COMLEX-USA Level 2-CE. The MCAT score for biological sciences had the highest correlation among all variables with COMLEX-USA Level 1 performance (Pearson r=0.304; P<.001) and Level 2-CE performance (Pearson r=0.272; P<.001). All preadmission variables were moderately correlated with the mean clinical subject examination scores. The mean clerkship evaluation score was moderately correlated with mean clinical examination results (Pearson r=0.267; P<.001) and COMLEX-USA Level 2-CE performance (Pearson r=0.301; P<.001). Clinical subject examination scores were highly correlated with COMLEX-USA Level 2-CE scores (Pearson r=0.817; P<.001). No statistically significant difference in medical school performance was found between students with science and nonscience undergraduate majors, nor was undergraduate institutional selectivity a factor influencing performance. Students' preadmission academic variables were predictive of osteopathic medical school performance, including GPAs, clinical performance, and COMLEX-USA Level 1 and Level 2-CE results. Clinical performance was predictive of COMLEX-USA Level 2-CE performance.

Weight bearing after lower extremity fractures still remains a highly controversial issue. Even in ankle fractures, the most common lower extremity injury no standard aftercare protocol has been established. Average non weight bearing times range from 0 to 7 weeks, with standardised, radiological healing controls at fixed time intervals. Recent literature calls for patient-adapted aftercare protocols based on individual fracture and load scenarios. We show the clinical feasibility and first results of a new, insole embedded gait analysis tool for continuous monitoring of gait, load and activity. Ten patients were monitored with a new, independent gait analysis insole for up to 3 months postoperatively. Strict 20 kg partial weight bearing was ordered for 6 weeks. Overall activity, load spectrum, ground reaction forces, clinical scoring and general health data were recorded and correlated. Statistical analysis with power analysis, t-test and Spearman correlation was performed. Only one patient completely adhered to the set weight bearing limit. Average time in minutes over the limit was 374 min. Based on the parameters load, activity, gait time over 20 kg weight bearing and maximum ground reaction force high and low performers were defined after 3 weeks. Significant difference in time to painless full weight bearing between high and low performers was shown. Correlation analysis revealed a significant correlation between weight bearing and clinical scoring as well as pain (American Orthopaedic Foot and Ankle Society (AOFAS) Score rs=0.74; Olerud-Molander Score rs=0.93; VAS pain rs=-0.95). Early, continuous gait analysis is able to define aftercare performers with significant differences in time to full painless weight bearing where clinical or radiographic controls could not. Patient compliance to standardised weight bearing limits and protocols is low. Highly individual rehabilitation patterns were seen in all patients. Aftercare protocols should be adjusted to real-time patient conditions, rather than fixed intervals and limits. With a real-time measuring device high performers could be identified and influenced towards optimal healing conditions early, while low performers are recognised and missing healing influences could be corrected according to patient condition.

To summarize application of rafting K-wires technique for tibial plateau fractures. From January 2013 to January 2015,45 patients with tibial plateau fractures were treated by locking plate with rafting K-wires, including 33 males and 12 females with an average of 44.2 years old ranging from 22 to 56 years old. According to Schatzker classification, 6 cases were type II, 8 were type Ill, 4 were type IV, 4 were type V, and 5 were type VI. Allogeneic bone graft were performed for bone defects. All patients were fixed with two to five K-wires. Part of weight loading were encouraged at 3 months after operation,and full weight-loading were done at 5 months after operation. Postoperative complications were observed,and Rasmussen clinical and radiological assessment were used to evaluate clinical results. All Patients were followed up from 10 to 23 months with average of 14 months. According to Rasmussen clinical and radiological assessment, clinical scores 23.58 ± 6.33, radiological scores were 14.00 ± 6.33; and excellent and good rates were 82.2% and 77.8% respectively. Four patients occurred severe osteoporosis and collapse of articular surface; 5 patients occurred traumatic arthritis. Rafting K-wires technique with anatomized armor plate could effective fix and support platform collapse and joint bone fragments, increase support surface area and reduce postoperative reduction loss rate.

Michener, Lori A; Snyder, Alison R; Leggin, Brian G

2011-02-01

The Numeric Pain Rating Scale (NPRS) is commonly used to assess pain. Change in the NPRS across time can be interpreted with responsiveness indices. To determine the minimal clinically important difference (MCID) of the NPRS. Single-group repeated measures. Outpatient rehabilitation clinics. Patients with shoulder pain (N = 136). At the initial evaluation patients completed the Penn Shoulder Score (PSS), which includes pain, satisfaction, and function sections. Pain was measured using an 11-point NPRS for 3 conditions of pain: at rest, with normal daily activities, and with strenuous activities. The NPRS average was calculated by averaging the NPRS scores for 3 conditions of pain. The final PSS was completed after 3-4 wk of rehabilitation. To determine the MCID for the NPRS average, the minimal detectible change of 8.6 points for the PSS function scale (0-60 points) was used as an external criterion anchor to classify patients as meaningfully improved (≥8.6 point change) or not improved (<8.6-point change). The MCID for the NPRS average was also determined for subgroups of surgical and nonsurgical patients. Cohen's effect sizes were calculated as a measure of group responsiveness for the NPRS average. Using a receiver-operating-characteristic analysis, the MCID for the average NPRS for all patients was 2.17, and it was 2.17 for both the surgical and nonsurgical subgroup: area-under-the-curve range .74-.76 (95%CI: .55-.95). The effect size for all patients was 1.84, and it was 1.51 and 1.94 for the surgical and nonsurgical groups, respectively. The NPRS average of 3 pain questions demonstrated responsiveness with an MCID of 2.17 in patients with shoulder pain receiving rehabilitation for 3-4 wk. The effect sizes indicated a large effect. However, responsiveness values are not static. Further research is indicated to assess responsiveness of the NPRS average in different types of patients with shoulder pain.

To describe the clinical features of idiopathic foveomacular retinoschisis not in association with myopia, glaucoma, optic disk pit, or juvenile retinoschisis. Retrospective observational case series. Five eyes of five patients with idiopathic foveomacular retinoschisis were included. The patients were 2 men and 3 women (average age, 75.2 years; range, 71-78 years). The average spherical equivalent was +2.40 diopters (range, +0.88 to +5.75 diopters), and the average axial length was 22.0 mm (range, 21.1-23.1 mm). All patients had retinoschisis from the macula to the optic disk in the affected eye. No patients had retinoschisis in the fellow eye. The average best-corrected visual acuity was 20/44 (68 Early Treatment Diabetic Retinopathy Study letter score). Idiopathic foveomacular retinoschisis is not inherited or associated with myopia, vitreomacular traction syndrome, optic pit, or glaucoma but is associated with older age, unilaterality, hyperopia with short axial length, complete posterior vitreous detachment, and weak leakage from the optic disk on fluorescein angiography.

Acoustic analysis of speech variables during depression and after improvement.

PubMed

Nilsonne, A

1987-09-01

Speech recordings were made of 16 depressed patients during depression and after clinical improvement. The recordings were analyzed using a computer program which extracts acoustic parameters from the fundamental frequency contour of the voice. The percent pause time, the standard deviation of the voice fundamental frequency distribution, the standard deviation of the rate of change of the voice fundamental frequency and the average speed of voice change were found to correlate to the clinical state of the patient. The mean fundamental frequency, the total reading time and the average rate of change of the voice fundamental frequency did not differ between the depressed and the improved group. The acoustic measures were more strongly correlated to the clinical state of the patient as measured by global depression scores than to single depressive symptoms such as retardation or agitation.

In the context of this study, a clinical audit of cases treated by a single orthodontist was carried out to illustrate one practical application of the PAR index. Fifty pairs of dental casts taken from the patient group before and at the end of orthodontic treatment were evaluated by an orthodontist trained in the use of the PAR index. This evaluation shows that the average overall PAR score for the subjects included in the study fell from an initial value of 25.64 ± 11.73 points to 1.78 ± 2.79 points at the end of orthodontic treatment. The average reduction attributable to orthodontic treatment was 23.86 ± 0.95 points, for an average percentage reduction of 93.36 ± 9.02%. When cases were classified according to the degree of improvement suggested by the nomogram of the PAR index, 23 (46%) were in the "Improved" category after treatment, and 27 cases (54%) in the "Greatly improved" category. This adds up to a total of 100% in these two categories, with none in the "No better" or "Worse" categories. It should be recalled that a high standard of orthodontic treatment is considered to be reached when the average percentage reduction of the PAR score exceeds 70% and when the number of cases in the "Worse or no better" category is below 5%.

Influence of guidance concept in complete dentures on oral health related quality of life - Canine guidance vs. bilateral balanced occlusion.

PubMed

Schierz, Oliver; Reissmann, Daniel

2016-10-01

To compare the impact of canine guided vs. bilateral balanced occlusion on oral health related quality of life (OHRQoL) as a patient-reported outcome measure. In this randomized single-blind crossover trial, 19 patients have been provided with new complete dentures in the maxilla and mandible. OHRQoL was assessed using the 49-item Oral Health Impact Profile (OHIP-49) before the start of the prosthodontic treatment (B), 3 months after insertion of the new dentures (T1), and 3 months after rework into the alternative concept (T2). Multilevel mixed-effect linear regression models were computed to determine the effect provided by the new set of dentures and the specific impact of the occlusal concept on OHRQoL using summary scores of the OHIP-49 and of a 19-items subset specific for edentulous patients (OHIP-EDENT). At baseline, participants' OHRQoL was substantially impaired indicated by an average OHIP-49 score of 42.1 points and an OHIP-EDENT score of 21.1 points. The effect of provision of a new set of complete dentures was a statistically significant decrease of 8.3 points (OHIP-49) and 4.0 points (OHIP-EDENT), respectively, representing a clinically relevant improvement in OHRQoL. When wearing dentures with bilateral balanced occlusion, participants showed on average 1.6 points higher OHIP-49 scores and 0.9 points higher OHIP-EDENT scores compared to canine guided dentures. This effect of the occlusal concept was neither statistically nor clinically significant. Both investigated occlusal concepts for complete dentures were comparable in their effect on patients' perceptions with none being considerably superior in terms of OHRQoL.

Our objective was to perform translation, cross-cultural adaptation and validation of the sino-nasal outcome test 22 (SNOT-22) to Spanish language. SNOT-22 was translated, back translated, and a pretest trial was performed. The study included 119 individuals divided into 60 cases, who met diagnostic criteria for chronic rhinosinusitis according to the European Position Paper on Rhinosinusitis 2012; and 59 controls, who reported no sino-nasal disease. Internal consistency was evaluated with Cronbach's alpha test, reproducibility with Kappa coefficient, reliability with intraclass correlation coefficient (ICC), validity with Mann-Whitney U test and responsiveness with Wilcoxon test. In cases, Cronbach's alpha was 0.91 both before and after treatment, as for controls, it was 0.90 at their first test assessment and 0.88 at 3 weeks. Kappa coefficient was calculated for each item, with an average score of 0.69. ICC was also performed for each item, with a score of 0.87 in the overall score and an average among all items of 0.71. Median score for cases was 47, and 2 for controls, finding the difference to be highly significant (Mann-Whitney U test, p < 0.001). Clinical changes were observed among treated patients, with a median score of 47 and 13.5 before and after treatment, respectively (Wilcoxon test, p < 0.001). The effect size resulted in 0.14 in treated patients whose status at 3 weeks was unvarying; 1.03 in those who were better and 1.89 for much better group. All controls were unvarying with an effect size of 0.05. The Spanish version of the SNOT-22 has the internal consistency, reliability, reproducibility, validity and responsiveness necessary to be a valid instrument to be used in clinical practice.

This study compared the impact of multipoint videoconferencing (VC) versus standard lecturing (ST) on primary care providers' (MDs, NPs/PAs, and RNs) education regarding hepatitis C virus (HCV). The hypothesis was that the educational impact of teaching through telemedicine is comparable to the traditional method. The aim was to provide participants clinically relevant information and knowledge about the natural history, diagnosis, and management of HCV. Improved knowledge was scored from a 10-item quiz administered before and after the educational intervention. Comparison of the pretest knowledge scores within provider groups showed no statistically significant difference in baseline knowledge for the ST versus VC method. However, for all practitioners combined, the VC group scored significantly lower on the pretest than the ST group (p < 0.05). All three types of learners improved their knowledge scores following intervention. On average, MDs and NP/PAs correctly answered two to 3.5 more questions in the posttest. RNs showed the greatest improvements, correctly answering an average of four to five more questions following intervention. Improvement in knowledge scores between the two methods was statistically significant in favor of VC for the MDs (VC = 3.56 +/- 1.92 vs. ST = 2.13 +/- 1.89, p < 0.001) and all groups combined (VC 4.37 +/- 1.92 vs ST 3.06 +/- 1.89, p < 0.001). The results of this study indicate that VC is equivalent, if not better, than standard continuing medical education (CME). VC can potentially improve clinician education regarding the history, diagnosis, and management of HCV, thereby making a substantial impact on the clinical course of patients with this condition. In addition, VC has the potential to eliminate the financial and geographic barriers to professional education for rural practitioners.

While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological determinants. So, the aim of the present study was to determine the plantar pressure pattern in participants with mild HV, comparing to a control group, and their clinical and anthropometric determinants. Biofoot/IBV(®) in-shoe system was used to evaluate 79 participants with mild HV. Computerized measurements of the 1st intermetatarsal angle (IMA) and the hallux abductus angle (HAA) were made on antero-posterior radiographs. The clinical outcome was assessed using the AOFAS score. The dependent baropodometric variables and the independent clinical and anthropometric variables were subjected to a multiple regression analysis. In both groups, the highest average pressure was in the 2nd metatarsal head (MTH). The mean pressure under the Hallux was significantly higher in HV group (controls, 146.5±92.5kPa; HV, 328.5±113.2kPa; p<0.001). An 18.6% of average pressure under the 1st MTH was accounted for pain, first ray alignment and total AOFAS score. Variations of the HAA explained 26.8% of the mean Hallux pressure. Women with mild HV present with pathologically increased pressure under the Hallux, which is caused by the altered alignment of the first ray. Pain and clinical result were associated with the pressure under the 1st MTH and the remaining variables were only moderate predictors of dynamic plantar pressures. Copyright © 2010 Elsevier B.V.

Methods Descriptive cross sectional study was conducted in 30 laboratory facilities including 6 laboratory sections to determine their status towards of accreditation using WHO AFRO accreditation checklist and 213 laboratory professionals were interviewed to assess their knowledge on quality system essentials and accreditation in Addis Ababa Ethiopia. Results Out of 30 laboratory facilities 1 private laboratory scored 156 (62%) points, which is the minimum required point for WHO accreditation and the least score was 32 (12.8%) points from government laboratory. The assessment finding from each section indicate that 2 Clinical chemistry (55.2% & 62.8%), 2 Hematology (55.2% & 62.8%), 2 Serology (55.2% & 62.8%), 2 Microbiology (55.2% & 62.4%), 1 Parasitology (62.8%) & 1 Urinalysis (61.6%) sections scored the minimum required point for WHO accreditation. The average score for government laboratories was 78.2 (31.2%) points, of these 6 laboratories were under accreditation process with 106.2 (42.5%) average score, while the private laboratories had 71.2 (28.5%) average score. Of 213 respondents 197 (92.5%) professionals had a knowledge on quality system essentials whereas 155 (72.8%) respondents on accreditation. Conclusion Although majority of the laboratory professionals had knowledge on quality system and accreditation, laboratories professionals were not able to practice the quality system properly and most of the laboratories had poor status towards the WHO accreditation process. Thus government as well as stakeholders should integrate accreditation program into planning and health policy. PMID:26889317

This clinical report describes the outpatient rehabilitation program for patients with multiple limb amputations enrolled in the Comprehensive Combat and Complex Casualty Care facility at the Naval Medical Center San Diego. Injury-specific data for 29 of these patients wounded by blast weaponry in Afghanistan in 2010 or 2011 were captured by the Expeditionary Medical Encounter Database at the Naval Health Research Center and were reviewed for this report. Their median Injury Severity Score was 27 (N = 29; range, 11-54). Patients averaged seven moderate to serious injuries (Abbreviated Injury Scale scores ≥2), including multiple injuries to lower limbs and injuries to the torso and/or upper limbs. All patients received care from numerous clinics, particularly physical therapy during the first 6 mo postinjury. Clinic use generally declined after the first 6 mo with the exception of prosthetic devices and repairs. The clinical team implemented the Mayo-Portland Adaptability Inventory, 4th Revision (MPAI-4) to assess functioning at outpatient program initiation and discharge (n = 23). At program discharge, most patients had improved scores for the MPAI-4 items assessing mobility, pain, and transportation, but not employment. Case reports described rehabilitation for two patients with triple amputations and illustrated multispecialty care and contrasting solutions for limb prostheses.

Objective ClinicalTrials.gov serves critical functions of disseminating trial information to the public and helping the trials recruit participants. This study assessed the readability of trial descriptions at ClinicalTrials.gov using multiple quantitative measures. Materials and Methods The analysis included all 165 988 trials registered at ClinicalTrials.gov as of April 30, 2014. To obtain benchmarks, the authors also analyzed 2 other medical corpora: (1) all 955 Health Topics articles from MedlinePlus and (2) a random sample of 100 000 clinician notes retrieved from an electronic health records system intended for conveying internal communication among medical professionals. The authors characterized each of the corpora using 4 surface metrics, and then applied 5 different scoring algorithms to assess their readability. The authors hypothesized that clinician notes would be most difficult to read, followed by trial descriptions and MedlinePlus Health Topics articles. Results Trial descriptions have the longest average sentence length (26.1 words) across all corpora; 65% of their words used are not covered by a basic medical English dictionary. In comparison, average sentence length of MedlinePlus Health Topics articles is 61% shorter, vocabulary size is 95% smaller, and dictionary coverage is 46% higher. All 5 scoring algorithms consistently rated CliniclTrials.gov trial descriptions the most difficult corpus to read, even harder than clinician notes. On average, it requires 18 years of education to properly understand these trial descriptions according to the results generated by the readability assessment algorithms. Discussion and Conclusion Trial descriptions at CliniclTrials.gov are extremely difficult to read. Significant work is warranted to improve their readability in order to achieve CliniclTrials.gov’s goal of facilitating information dissemination and subject recruitment. PMID:26269536

2011-01-01

Context: Double-row rotator cuff repair methods have improved biomechanical performance when compared with single-row repairs. Objective: To review clinical outcomes of single-row versus double-row rotator cuff repair with the hypothesis that double-row rotator cuff repair will result in better clinical and radiographic outcomes. Data Sources: Published literature from January 1980 to April 2010. Key terms included rotator cuff, prospective studies, outcomes, and suture techniques. Study Selection: The literature was systematically searched, and 5 level I and II studies were found comparing clinical outcomes of single-row and double-row rotator cuff repair. Coleman methodology scores were calculated for each article. Data Extraction: Meta-analysis was performed, with treatment effect between single row and double row for clinical outcomes and with odds ratios for radiographic results. The sample size necessary to detect a given difference in clinical outcome between the 2 methods was calculated. Results: Three level I studies had Coleman scores of 80, 74, and 81, and two level II studies had scores of 78 and 73. There were 156 patients with single-row repairs and 147 patients with double-row repairs, both with an average follow-up of 23 months (range, 12-40 months). Double-row repairs resulted in a greater treatment effect for each validated outcome measure in 4 studies, but the differences were not clinically or statistically significant (range, 0.4-2.2 points; 95% confidence interval, –0.19, 4.68 points). Double-row repairs had better radiographic results, but the differences were also not statistically significant (P = 0.13). Two studies had adequate power to detect a 10-point difference between repair methods using the Constant score, and 1 study had power to detect a 5-point difference using the UCLA (University of California, Los Angeles) score. Conclusions: Double-row rotator cuff repair does not show a statistically significant improvement in clinical outcome or radiographic healing with short-term follow-up. PMID:23016017

To assess the early postoperative clinical and radiographic outcomes after navigation-assisted or standard instrumentation total knee arthroplasty (TKA). From August 2007 to May 2008, 60 KSS-A type patients underwent 67 primary TKA operations by the same surgical team. Twenty-two operations were performed with the Image-free navigation system with an average age of 64.5 years while the remaining 45 underwent conventional manual procedures with an average age of 66 years. Their preoperative demographic and functional data had no statistical differences (P>0.05). The operative duration, blood loss volume and hospitalization days were compared for two groups. And radiographic data included coronal femoral component angle, coronal tibial component angle, sagittal femoral component angle, sagittal tibial component angle and coronal tibiofemoral angle after one month. And functional assessment scores were evaluated at 1, 3 and 6 months postoperatively. Operative duration was significantly longer for computer navigation (P<0.05). The average blood loss volume was 555.26 ml in computer navigation group and 647.56 ml in conventional manual method group (P<0.05). And hospitalization stay was shorter in computer navigation group than that in conventional method group (7.74 vs 8.68 days) (P=0.04). The alignment deviation was better in computer-assisted group than that in conventional manual method group (P<0.05). The percentage of patients with a coronal tibiofemoral angle within ±3 of ideal value was 95.45% for computer-assisted mini-invasive TKA group and 80% for conventional TKA group (P=0.003). The Knee Society Clinical Rating Score was higher in computer-assisted group than that in conventional manual method group at 1 and 3 montha post-operation. However, no statistical inter-group difference existed at 6 months post-operation. Navigation allows a surgeon to precisely implant the components for TKA. And it offers faster functional recovery and shorter hospitalization stay. At 6 months post-operation, there is no statistical inter-group difference in KSS scores.

2015-01-01

Objective The purpose of this study was to examine literature on radiological student evaluation and outcome assessments including national board examinations. Methods A review of the literature was performed using relevant key words. Articles were retrieved through December 2012 using PubMed, ScienceDirect, ERIC, Proquest, and ICL databases along with a manual review of references. Results Of the 4716 unique abstracts reviewed by the author, 54 were found to be relevant to the purpose of this study. Student grade point average correlates with board scores in the nursing, chiropractic, and medical professions. Scores on the chiropractic college admission test and undergraduate grade point average correlate with success in professional college. There is a correlation between board scores and college attended. Board preparation programs do not appear to affect board examination scores. Conclusion Although evaluations can be effective teaching tools, they are not used by many radiology programs. Some programs have inadequate evaluations and do not allow students to review their evaluations. There are no definitive links between mastery of radiology and specific evaluations, outcomes, or pre-professional/clinical grades. Studies suggest that board examination scores reflect long-term mastery of knowledge rather than short-term memorization of facts. PMID:26770174

In recent years, most Dutch general practitioners started working under the umbrella of diabetes care groups, responsible for the organisation and coordination of diabetes care. The quality management of these new organisations receives growing interest, although its association with quality of diabetes care is yet unclear. The best way to measure quality management is unknown and it has not yet been studied at the level of outpatient clinics or care groups. We aimed to assess quality management of type 2 diabetes care in care groups and outpatient clinics. Quality management was measured with online questionnaires, containing six domains (see below). They were divided into 28 subdomains, with 59 (care groups) and 57 (outpatient clinics) questions respectively. The mean score of the domains reflects the overall score (0-100%) of an organisation. Two quality managers of all Dutch care groups and outpatient clinics were invited to fill out the questionnaire.Sixty care groups (response rate 61.9%) showed a mean score of 59.6% (CI 57.1-62.1%). The average score in 52 outpatient clinics (response rate 50.0%) was 61.9% (CI 57.5-66.8%).Mean scores on the six domains for care groups and outpatient clinics respectively were: 'organisation of care' 71.9% (CI 68.8-74.9%), 76.8% (CI 72.8-80.7%); 'multidisciplinary teamwork' 67.1% (CI 62.4-71.9%), 71.5% (CI 65.3-77.8%); 'patient centeredness' 46.7% (CI 42.6-50.7%), 62.5% (CI 57.7-67.2%); 'performance management' 63.3% (CI 61.2-65.3%), 50.9% (CI 44.2-57.5%); 'quality improvement policy' 52.6% (CI 49.2-56.1%), 50.9% (CI 44.6-57.3%); and 'management strategies' 56.0% (CI 51.4-60.7%), 59.0% (CI 52.8-65.2%). On subdomains, care groups scored highest on 'care program' (83.3%) and 'measured outcomes' (98.3%) and lowest on 'patient safety' (15.1%) and 'patient involvement' (17.7%). Outpatient clinics scored high on the presence of a 'diabetic foot team' (81.6%) and the support in 'self-management' (81.0%) and low on 'patient involvement' (26.8%) and 'inspection of medical file' (28.0%). This nationwide assessment reveals that the level of quality management in diabetes care varies between several subdomains in both diabetes care groups and outpatient clinics.

We present the surgical technique of rim-plate-augmented separate vertical wiring for comminuted inferior pole fracture of the patella and report the clinical outcomes. Between July 2013 and January 2016, 13 patients (7 male and 6 female) who were diagnosed with comminuted inferior pole fracture of the patella in preoperative computed tomography and underwent a minimum of 1 year of follow-up were enrolled in this study. Mean patient age was 57.7 years (range 28-72 years). All patients underwent open reduction and internal fixation by rim-plate-augmented separate vertical wiring. Bony union, complications, range of motion and Bostman score were the clinical outcomes. Bony union was achieved in all cases at an average of 10 weeks after surgery (range 8-12). There was no loss of reduction and fixative failure during follow-up. The average range of motion was 127° (range 120°-130°). The mean Bostman score at last follow-up was 29.6 points (range 27-30) and graded excellent in 12 patients. Rim-plate-augmented separate vertical wiring demonstrated secure fixation and favorable clinical outcomes. This study provides evidence for its effectiveness as a fixation method for treating displaced, comminuted inferior pole fracture of the patella.

To compare the level of anxiety and performance of nursing students when performing a clinical simulation through the traditional method of assessment with the presence of an evaluator and through a filmed assessment without the presence of an evaluator. Controlled trial with the participation of Brazilian public university 20 students who were randomly assigned to one of two groups: a) assessment through the traditional method with the presence of an evaluator; or b) filmed assessment. The level of anxiety was assessed using the Zung test and performance was measured based on the number of correct answers. Averages of 32 and 27 were obtained on the anxiety scale by the group assessed through the traditional method before and after the simulation, respectively, while the filmed group obtained averages of 33 and 26; the final scores correspond to mild anxiety. Even though there was a statistically significant reduction in the intra-groups scores before and after the simulation, there was no difference between the groups. As for the performance assessments in the clinical simulation, the groups obtained similar percentages of correct answers (83% in the traditional assessment and 84% in the filmed assessment) without statistically significant differences. Filming can be used and encouraged as a strategy to assess nursing undergraduate students.

To explore the clinical effects of the triple no loop Endobutton plate combined with Orthcord line in treating acromioclavicular dislocation of Tossy type III. Between February 2011 and September 2013, 36 patients with acromioclavicular dislocation of Tossy type III were treated with triple no loop Endobutton plate and Orthcord line. There were 21 males and 15 females, aged from 9 to 48 years old with an average of (26.41±14.05) years. Couse of disease was from 2 to 7 days in the patients. The patients had the clinical manifestations such as shoulder pain, extension limited, acromioclavicular tenderness, positive organ point sign. Clinical effects were assessed by acromioclavicular scoring system. Thirty six patients were followed up from 8 to 15 months with an average of (12.2±4.3) months. All incisions got primary healing. At the final follow up, all shoulder pain vanished, acromioclavicular joints without tenderness, negative organ point sign. No redislocation and steel plate loosening were found. According to the acromioclavicular scoring system, 31 cases obtained excellent results, 5 good. The method of triple no loop Endobutton plate combined with Orthcord line for acromioclavicular dislocation of Tossy type III has advantage of less risk and complication, good functional rehabilitation and is an ideal method.

This study examined compulsive sexual behavior (CSB) and psychopathology in a treatment-seeking sample of men in São Paulo, Brazil. Eighty-six men (26% gay, 17% bisexual, 57% heterosexual) who met diagnostic criteria for excessive sexual drive and sexual addiction completed assessments consisting of the Mini International Neuropsychiatric Interview, a structured clinical interview for DSM-IV Axis I Disorders-Clinical Version (segment for Impulse Control Disorder), Sexual Compulsivity Scale (SCS), and questions about problematic CSB. The average SCS score for our sample was above the cut-off score reported in other studies, and 72% of the sample presented at least one Axis I psychiatric diagnosis. There were no differences among gay, bisexual, and heterosexual men on SCS scores and psychiatric conditions, but gay and bisexual men were more likely than heterosexual men to report casual sex and sex with multiple casual partners as problematic behaviors. SCS scores were associated with psychiatric co-morbidities, mood disorder, and suicide risk, but diagnosis of a mood disorder predicted higher SCS scores in a regression analysis. The study provides important data on the mental health needs of men with CSB in São Paulo, Brazil. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

To analyze patients with a confirmed voice disorder in order to identify patterns regarding age, gender, and occupation compared to the general public. To explore effects of voice therapy according to the Voice Handicap Index (VHI) score pre- and post-therapy in relation to the number of sessions, age, and gender. Prospective cohort study. This study was conducted as a collaborative project between Linköping University and hospitals in the south-east health care region in Sweden. Six voice clinics participated by asking their patients voluntarily to complete the Swedish version of the VHI at the beginning and end of therapy. The two most prevalent diagnoses were dysphonia (43%) and phonasthenia (25%). Among the working population, the three most common occupational fields were education, health care, and child-care. The majority of the patients were women (74.3%), and the mean age of all patients was 55 years. A significant improvement in VHI scores was found after therapy, with an average decrease of 19 median points in total score and a substantial effect size (0.55). The number of sessions did not significantly correlate with the mean VHI score difference but had a weak correlation to the start and end scores. Increasing age correlated with a higher median VHI score both at the start and end of therapy but did not affect the average decrease between the two measurements.

This study aims to determine factors of job satisfaction and burnout levels of paediatric nurses. A total of 165 nurses working in paediatric clinics completed the Minnesota job satisfaction scale and the Maslach burnout scale. Average scores of the emotional exhaustion and depersonalisation score were low, while personal accomplishment scores were high. A high level of job satisfaction, being married, increased age and a decreased number of assigned patients were significantly associated with a low level of burnout. Paediatric nurses experience burnout at significant levels. The most important variable that affected job satisfaction was income. The results of the study could guide development of strategies that might prevent or alleviate burnout of paediatric nurses. © 2016 John Wiley & Sons Ltd.

Depression is common among women, specially during breeding. To characterize post-partum depression in a group of women attending a primary health care clinic and its relationship to quality of life. The sample included women meeting criteria for Major Depression, with a child of up to 11 months old. Exclusion criteria included the presence of psychosis, history of mania, alcohol abuse, illegal drug use, high suicide risk, and receiving mental health care in the last three months. Structured interviews used were the Edinburgh postpartum depression scale (EPDS), Mini International Neuropsychiatric Interview (MINI), Medical Outcomes Study Questionnaire (SF-36) and questions about incapacity and health care use. The sample included 159 women with a median age of 27 years (range: 16-43 years). Thirty three percent were married, 30.8% lived in common law marriage, 9.4% were divorced, and 26.4% were single. Most (89.3%) were housewives, 31% were students, and 6.9% were employed. The average score on the EPDS was 17 points (S.D. 4.2). The average SF-36 somatic score was 42.7 points (S.D. 8.2), and the emotional score was 30.3 (D.S. 0.3). The relation between the average score on the EPDS and the somatic and emotional scores was statistically significant (p=0.000-0.006). Most women were mildly to moderately depressed. Their depression was associated with a marked impairment of activities of daily living. These findings add to the evidence suggesting that depression is associated with marked disability cultures, even when the depression is mild to moderate.

Introduction Patient satisfaction and health care outcomes are directly linked to useful communication skills. Therefore, excellent interpersonal skills are imperative for health care professionals. Multiple mini-interview (MMI) is designed as a selection tool to assess the communication skills of applicants in medical schools during the admission process. However, objective structured clinical examination (OSCE) assesses students’ communication and clinical skills at the end of their academic terms. Recently, Anglia Ruskin University, Chelmsford, UK, adopted MMI in the selection process for the first cohort of MSc Physician Associate trainees for the academic year 2015–2016. This study aimed to determine the likelihood of MMI as a predictor of future performance of communication skills in the OSCE. Materials and methods The anonymous data of the average scores of communication skills attained in MMI and OSCE at the end of year 1 were collected for 30 students from the Physician Associate program team. Subsequently, Pearson’s correlation was computed to determine the relationship between the average scores of communication skills attained in MMI, and OSCE during trimester 2 and trimester 3 by the Physician Associate trainees. Results The study showed positive correlation between the scores of communication skills attained in MMI and OSCE during trimester 2 (r=0.956, n=30, p<0.001) and trimester 3 (r=0.966, n=30, p<0.001). Conclusion The study provides empirical evidence for the validity of MMI as a predictor of future performance of Physician Associate trainees’ communication skills during subsequent OSCEs.

Lyme disease is the most common vector-borne disease in the United States. Some patients report persistent or intermittent subjective symptoms of mild to moderate intensity after antibiotic treatment for Lyme disease. We sought to evaluate trends in clinical and quality-of-life (QOL) measures in a cohort of patients with Lyme disease enrolled in a natural history study at the National Institutes of Health from 2001-2014. QOL was measured using the self-administered 36-item Short Form Health Survey (SF-36) during study follow-up. Primary outcomes included mean physical (PCS) and mental (MCS) health QOL composite scores and reporting long-term (≥2 years) symptoms, adjusted for Lyme disease stage and severity at diagnosis. Overall, 101 patients with an average follow-up time of 3.9 years (range, 0.5-11.3 years) were included. At first visit, overall mean QOL scores were below the US population mean for both PCS (45.6 ± 10.4) and MCS (47.3 ± 11.5) but increased to just above the national average after 3 years of follow-up for both PCS (50.7 ± 9.6) and MCS (50.1 ± 10.0). Baseline QOL scores were lowest in those with late disease (P < 0.01) but also increased by the end of follow-up to national averages. In multivariate analysis, the only factors significantly associated with long-term symptoms or lower QOL scores were other comorbidities unrelated to Lyme disease. Comorbid conditions can play a role in the reporting of long-term symptoms and overall QOL of Lyme disease patients and should be considered in the evaluation of these patients. NCT00028080.

Onychomycosis is a relatively common fungal infection. Current treatments have limited applicability and low cure rates. Recently introduced laser therapy has shown to be a safe and effective treatment for onychomycosis. In this study, we evaluate a submillisecond Nd:YAG 1,064 nm laser for treating onychomycoses of the tonail. Thirteen subjects (9 female, 4 male) with 37 affected toenails received 1 to 3 treatments 4 and/or 8 weeks apart with a sub-millisecond 1,064 nm Nd:YAG laser. Diagnosis of onychomycosis was confirmed with microscopy. Average follow-up time was 16 weeks post-final treatment. Photos were taken and degree of turbidity was determined using a turbidity scale (ranging from "0 = clear nail" to "10 = completely turbid nail") at each visit. Improvement in turbidity was determined by comparison of turbidity scores at baseline and 16-week follow-up on average. Efficacy was assessed by an overall improvement scale (0 to 4), which combined improvement in turbidity scores and microscopic examination. Overall improvement was classified as "4 = complete clearance" if the turbidity score indicated "0 = clear nail" accompanied by a negative microscopic result. No microscopic examination was performed unless the turbidity score showed "0 = clear nail." Treatments were well tolerated by all subjects and there were no adverse events. Of the 37 toenails treated, 30 (81%) had "moderate" to "complete" clearance average of 16 weeks post-final treatment. Nineteen toenails (51%) were completely clear and all tested negative for fungal infection on direct microscopic analysis. Seven (19%) toenails had significant clearance and four (11%) had moderate clearance. The preliminary results of this study show this treatment modality is safe and effective for the treatment of onychomycosis in the short term. Additional studies are needed to more fully assess the clinical and mycological benefits as well as optimize the treatment protocol and parameters.

To evaluate the effect of the Aging Brain Care (ABC) Medical Home program's depression module on patients' depression severity measurement over time. Retrospective chart review. Public hospital system. Patients enrolled in the ABC Medical Home program between October 1, 2012 and March 31, 2014. The response of 773 enrolled patients who had multiple patient health questionnaire-9 (PHQ-9) scores recorded in the ABC Medical Home program's depression care protocol was evaluated. Repeatedly measured PHQ-9 change scores were the dependent variables in the mixed effects models, and demographic and comorbid medical conditions were tested as potential independent variables while including random effects for time and intercept. Among those patients with baseline PHQ-9 scores >10, there was a significant decrease in PHQ-9 scores over time ( P <0.001); however, the effect differed by gender ( P =0.015). On average, women's scores (4.5 point drop at 1 month) improved faster than men's scores (1 point drop at 1 month). Moreover, both men and women had a predicted drop of 7 points (>50% decline from baseline) on the PHQ-9 at 6 months. These analyses demonstrate evidence for the sustained effectiveness of the ABC Medical Home program at inducing depression remission outcomes while employing clinical staff who required less formal training than earlier clinical trials.

To compare the application time and the capacity of the nomograms to predict the success of Guy's Stone Score (GSS), S.T.O.N.E. Nephrolithometry (STONE) and Clinical Research Office of the Endourological Society nephrolithometric nomogram (CROES) of percutaneous nephrolithotomy (PCNL), evaluating the most efficient one for clinical use. We studied 48 patients who underwent PCNL by the same surgeon between 2010 and 2011. We calculated GSS, STONE and CROES based on preoperative non-contrast computed tomography (CT) images and clinical data. A single observer, blinded to the outcomes, reviewed all images and assigned scores. We compared the application time of each nomogram. We used an analysis of variance for repeated measures and multiple comparisons by the Tukey test. We compared the area under the ROC curve (AUC) of the three nomograms two by two to determine the most predictive scoring system. The immediate success rate was 66.7% and complications occurred in 16.7% of cases. The average operative time was 122 minutes. Mean application time was significantly lower for the GSS (27.5 seconds) when compared to 300.6 seconds for STONE and 213.4 seconds for CROES (p<0.001). There was no significant difference among the GSS (AUC=0.653), STONE (AUC=0.563) and CROES (AUC=0.641) in the ability to predict immediate success of PCNL. All three nomograms showed similar ability to predict success of PCNL, however the GSS was the quickest to be applied, what is an important issue for routine clinical use when counseling patients who are candidates to PCNL.

Background Ferumoxytol is an ultrasmall superparamagnetic iron oxide (USPIO) nanoparticle agent used to treat iron deficiency anemia in adults with chronic kidney disease. Objective We aim to determine the feasibility of using of ferumoxytol for clinical pediatric cardiac and vascular imaging. Material and methods We retrospectively identified 23 consecutive children who underwent MRI with ferumoxytol (11 males; mean age: 7.4 years, range: 3 days–18 years), yielding 12 abdominal MR angiography and 15 cardiac MRI studies. Medical records were reviewed for the clinical indication, ferumoxytol dose, injection rate, sedation and any complication. A two-reader consensus scored the images on a 5-point scale for overall image quality and delineation of various anatomical structures. Signal-to-background ratios for abdominal aorta and inferior vena cava for abdominal cases and blood pool-myocardium contrast ratios for cardiac cases were calculated. The confidence intervals for obtaining a score of 3 or above for each image parameter were calculated by using adjusted Wald method. Results For abdominal MR angiography, average scores for overall image quality, as well as delineation of the hepatic artery, superior mesenteric artery, renal artery, and veins were 4.5, 4.3, 4.3, 3.7 and 4.7, respectively. For cardiac exams, the average scores for overall image quality, systemic arteries, pulmonary arteries, pulmonary veins, valves and ventricles were 4.4, 4.6, 4.1, 4.8, 4.1 and 4.7, respectively. For all parameters, lower bound for proportion of cases to have a score of 3 or above was 65%. Signal-to-background ratios for aorta and abdominal veins averaged 86 +/− 74 and 86 +/− 77 for full-dose images, and 23 and 18 for half-dose images, respectively. Mean blood pool to myocardium contrast ratio was 3:3. Conclusion Ferumoxytol can provide excellent image quality for pediatric body MR angiography/MR venography at a dose of 1.5 or 3 mg Fe/kg. Further investigation should be directed toward understanding the lowest dose that can be administered. PMID:25427433

The Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UDPRS) is a commonly used tool to measure Parkinson disease (PD) progression. Longitudinal changes in MDS-UPDRS scores in de novo PD have not been established. Determine progression rates of MDS-UPDRS scores in de novo PD. 362 participants from the Parkinson's Progression Markers Initiative, a multicenter longitudinal cohort study of de novo PD, were included. Longitudinal progression of MDS-UPDRS total and subscale scores were modeled using mixed model regression. MDS-UPDRS scores increased in a linear fashion over five years in de novo PD. MDS-UPDRS total score increased an estimated 4.0 points/year, Part I 0.25 points/year, Part II 1.0 points/year, and Part III 2.4 points/year. The expected average progression of MDS-UPDRS scores in de novo PD from this study can assist in clinical monitoring and provide comparative data for detection of disease modification in treatment trials.

The use of standardized patients in the plastic surgery residency curriculum: teaching core competencies with objective structured clinical examinations.

PubMed

Davis, Drew; Lee, Gordon

2011-07-01

As of 2006, the Accreditation Council for Graduate Medical Education had defined six "core competencies" of residency education: interpersonal communication skills, medical knowledge, patient care, professionalism, practice-based learning and improvement, and systems-based practice. Objective structured clinical examinations using standardized patients are becoming effective educational tools, and the authors developed a novel use of the examinations in plastic surgery residency education that assesses all six competencies. Six plastic surgery residents, two each from postgraduate years 4, 5, and 6, participated in the plastic surgery-specific objective structured clinical examination that focused on melanoma. The examination included a 30-minute videotaped encounter with a standardized patient actor and a postencounter written exercise. The residents were scored on their performance in all six core competencies by the standardized patients and faculty experts on a three-point scale (1 = novice, 2 = moderately skilled, and 3 = proficient). Resident performance was averaged for each postgraduate year, stratified according to core competency, and scored from a total of 100 percent. Residents overall scored well in interpersonal communications skills (84 percent), patient care (83 percent), professionalism (86 percent), and practice-based learning (84 percent). Scores in medical knowledge showed a positive correlation with level of training (86 percent). All residents scored comparatively lower in systems-based practice (65 percent). The residents reported unanimously that the objective structured clinical examination was realistic and educational. The objective structured clinical examination provided comprehensive and meaningful feedback and identified areas of strengths and weakness for the residents and for the teaching program. The examination is an effective assessment tool for the core competencies and a valuable adjunct to residency training.

To prospectively compare long-term clinical and radiological outcomes following a cruciate retaining fixed-bearing (FB) and a mobile-bearing (MB) primary total knee replacement (TKR). We prospectively reviewed 113 TKRs in 99 patients (14 bilateral) with a PFC sigma cruciate retaining rotating platform system, at an average follow-up of 11.1 years (range 10-12). Results were contrasted with those from 89 TKRs in 72 patients (17 bilateral) with a PFC sigma cruciate fixed-bearing prosthesis, at an average follow-up of 12.1 years (range 10-14.1). Outcomes collected included pre- and post-operative range of motion, Oxford Knee Scores, complications encountered, as well as radiographical assessments of polyethylene wear. In the MB group, mean Oxford Knee Scores improved from 16 pre-operatively to 42 at final follow-up. The mean range of motion was 115° (75-130). In the FB group, mean Oxford Knee Scores improved from 16.2 pre-operatively to 42.5 at final follow-up. The mean range of motion was 111.2 (80-135) degrees at final follow-up. We failed to elicit an objectively demonstrable clinical difference between the MB- and FB-implanted knees. Similarly, radiological benefits of the MB implants with regard to polyethylene wear were not evident at a minimum 10-year follow-up.

To investigate the feasibility and therapeutic effect of subcutaneous pedicle screw-rod system with modified placement in treatment of Tile B pelvic fractures. From June 2014 to August 2015, 14 patients with Tile B pelvic fractures were treated by subcutaneous pedicle screw-rod system with modified placement in the anterior inferior iliac spine and pubic tubercle. There were 8 males and 6 females, aged from 23 to 65 years with an average of 42 years. Operative time, intraoperative blood loss, fracture healing and postoperative complication were observed and clinical effects were evaluated by Matta reduction standard and Majeed score. All patients were followed up from 8 to 15 months with an average of 10.5 months. Operative time was 25 to 45 min with an average of 32 min;intraoperative blood loss was 10 to 35 ml with an average of 18 ml. All fractures got primary healing and healed time was 9 to 14 weeks with an average of 12.5 weeks. No postoperative incision infection, internal fixation failure and ectopic ossification were found, 4 cases occurred unilateral lateral femoral cutaneous nerve injury and 1 case occurred unilateral femoral nerve paralysis, but all restored finally. According to Matta criteria, reduction was excellent in 7 cases, good in 5 cases, fair in 2 case. According to Majeed score system, the functional evaluation at last follow-up was excellent in 5 cases, good in 7 cases, fair in 2 cases with the average score of 81.50±8.05. Subcutaneous pedicle screw-rod system with modified placement in the anterior inferior iliac spine and pubic tubercle have advantages of strong reduction, less trauma and complications, and is a promising surgical method in the treatment of Tile B pelvic fractures.

To assess the effect of a structured postgraduate year 1 educational curriculum, including online surgical training, on American Board of Surgery In-Training Examination (ABSITE) scores. This was a retrospective cohort study. The study was performed in an academic surgical residency program in a tertiary care hospital, Cleveland Clinic Foundation, Cleveland, Ohio. The participants were 140 surgical postgraduate year 1 residents from 2000 to 2009. Interns from 2000 to 2004 were grouped together and completed a self-directed learning curriculum. Interns from 2005 to 2009 participated in a structured educational curriculum that included lectures and the use of an online program. Lectures were based on the American College of Surgeons curriculum. The online program consisted of 8 to 12 hours of assigned tutorials and quizzes that corresponded to the lectures and 3 multiple-choice (MC) examinations. Use of a structured educational curriculum led to improved ABSITE scores (66 ± 9%) compared with that of those who had no curriculum (55 ± 10%, p < 0.001). Several variables positively correlated with the ABSITE score: United States Medical Licensing Examination step 1 score (p < 0.001), monthly quiz scores (p = 0.003), average MC examination scores (p = 0.005), lecture attendance (p = 0.02), and time spent online (p = 0.04). Multivariable analysis demonstrated that the step 1 United States Medical Licensing Examination score, time spent online, and MC examination score are predictive of total the ABSITE score. When ABSITE subscores (basic science and clinical science) were compared, the online curriculum had a greater effect on basic science subscores, whereas lectures had a greater effect on clinical science subscores. Providing surgery residents a structured curriculum with lectures and an online component positively impacts ABSITE scores. Copyright © 2015 Association of Program Directors in Surgery.

Performance of the Hack's Impairment Index Score: A Novel Tool to Assess Impairment from Alcohol in Emergency Department Patients.

PubMed

Hack, Jason B; Goldlust, Eric J; Ferrante, Dennis; Zink, Brian J

2017-10-01

Over 35 million alcohol-impaired (AI) patients are cared for in emergency departments (EDs) annually. Emergency physicians are charged with ensuring AI patients' safety by identifying resolution of alcohol-induced impairment. The most common standard evaluation is an extemporized clinical examination, as ethanol levels are not reliable or predictive of clinical symptoms. There is no standard assessment of ED AI patients. The objective was to evaluate a novel standardized ED assessment of alcohol impairment, Hack's Impairment Index (HII score), in a busy urban ED. A retrospective chart review was performed for all AI patients seen in our busy urban ED over 24 months. Trained nurses evaluated AI patients with both "usual" and HII score every 2 hours. Patients were stratified by frequency of visits for AI during this time: high (≥ 6), medium (2-5), and low (1). Within each category, comparisons were made between HII scores, measured ethanol levels, and usual nursing assessment of AI. Changes in HII scores over time were also evaluated. A total of 8,074 visits from 3,219 unique patients were eligible for study, including 7,973 (98.7%) with ethanol levels, 5,061 (62.7%) with complete HII scores, and 3,646 (45.2%) with health care provider assessments. Correlations between HII scores and ethanol levels were poor (Pearson's R 2  = 0.09, 0.09, and 0.17 for high-, medium-, and low-frequency strata). HII scores were excellent at discriminating nursing assessment of AI, while ethanol levels were less effective. Omitting extrema, HII scores fell consistently an average 0.062 points per hour, throughout patients' visits. The HII score applied a quantitative, objective assessment of alcohol impairment. HII scores were superior to ethanol levels as an objective clinical measure of impairment. The HII declines in a reasonably predictable manner over time, with serial evaluations corresponding well with health care provider evaluations. © 2017 by the Society for Academic Emergency Medicine.

Estimation of the infarct size from body-surface ECGs in post-myocardial infarction patients has become possible using the Selvester scoring method. Automation of this scoring has been proposed in order to speed-up the measurement of the score and improving the inter-observer variability in computing a score that requires strong expertise in electrocardiography. In this work, we evaluated the quality of the QuAReSS software for delivering correct Selvester scoring in a set of standard 12-lead ECGs. Standard 12-lead ECGs were recorded in 105 post-MI patients prescribed implantation of an implantable cardiodefibrillator (ICD). Amongst the 105 patients with standard clinical left bundle branch block (LBBB) patterns, 67 had a LBBB pattern meeting the strict criteria. The QuAReSS software was applied to these 67 tracings by two independent groups of cardiologists (from a clinical group and an ECG core laboratory) to measure the Selvester score semi-automatically. Using various level of agreement metrics, we compared the scores between groups and when automatically measured by the software. The average of the absolute difference in Selvester scores measured by the two independent groups was 1.4±1.5 score points, whereas the difference between automatic method and the two manual adjudications were 1.2±1.2 and 1.3±1.2 points. Eighty-two percent score agreement was observed between the two independent measurements when the difference of score was within two point ranges, while 90% and 84% score agreements were reached using the automatic method compared to the two manual adjudications. The study confirms that the QuAReSS software provides valid measurements of the Selvester score in patients with strict LBBB with minimal correction from cardiologists. Copyright © 2015 Elsevier Inc.

We investigated the safety, tolerability and efficacy of a low energy low density, non-ablative fractional 1,927-nm laser in the treatment of facial photodamage, melasma, and post inflammatory hyperpigmentation. Prospective non-randomized trial. Single center, private practice with a dedicated research department. Subjects with clinically diagnosed facial photodamage, melasma, or post inflammatory hyperpigmentation. Subjects received four to six treatments at 14-day intervals (+/- 3 days) with a low energy low density non-ablative fractional 1,927-nm laser (Solta Hayward, CA) with an energy level of 5 mJ, and density coverage of either 5%, 7.5%, or 10%, with a total of up to 8 passes. Blinded assessment of clinical photos for overall improvement at one and three months post final treatment. Investigator improvement scores, and subject pain and satisfaction scores for overall improvement were recorded as well. We enrolled 23 subjects, average age 45.0 years (range, 25-64 years), 22 with Fitzpatrick Skin Types I-IV and 1 with Type VI, with facial photodamage, melasma, or post inflammatory hyperpigmentation. Approximately 55% of subjects reported marked to very significant improvement at one and three months post final treatment. Blinded assessment of photography of 20 subjects revealed an average of moderate improvement at one-month follow up and mild to moderate improvement at three months. Average subject pain score was 3.4/10 during treatment. Favorable outcomes were demonstrated using the low energy low density, non-ablative fractional 1,927-nm laser in facial resurfacing for photodamage, melasma, and post inflammatory hyperpigmentation. Results were maintained at the 3-month follow up, as demonstrated by investigator and subject assessments, as well as blinded evaluations by three independent dermatologists utilizing photographs obtained from a standardized facial imaging device.

Calcaneal fracture malunion may evolve into arthrosis and severe foot deformities. The aim of this study was to identify differences in bony union following corrective subtalar arthrodesis with interposition of autologous tricortical bone graft or freeze-dried bovine xenograft. We prospectively evaluated 12 patients who underwent subtalar arthrodesis, six patients received autografts and 6 received freeze-dried bovine xenografts. After a mean followup of 58 weeks, the patients were clinical assessed using AOFAS scale and the visual analog scale (VAS) for pain and for final radiographic parameters measurement. Two blind raters evaluated the length of time required for solid union of the arthrodesis and graft integration by retrospective radiographic examination. In the autograft group, AOFAS score improved from a preoperative average of 37 to 64 points postoperatively (p = 0.02) and mean VAS score improved from 4.7 to 1.9 (p = 0.028). In the xenograft group, AOFAS score improved from 38 to 74 points (p = 0.02) and VAS from 5.5 to 2.7 (p = 0.046). Solid union was achieved in all cases in the autograft group at an average of 5.3 weeks and in five cases in the xenograft group at 8.8 weeks (p = 0.077). Graft integration occurred after an average of 10.7 weeks in the autograft group and 28.8 weeks in the xenograft group (p = 0.016). With the numbers available, no significant difference could be detected in the length of time required for solid union of subtalar arthrodesis between groups, although time to integration of freeze-dried bovine xenografts was statistically higher. Clinical and functional improvement was observed in both groups.

Reliability of Left Ventricular Hypertrophy by ECG Criteria in Children with Syncope: Do the Criteria Need to be Revised?

In the outpatient setting, children who present with syncope routinely undergo electrocardiograms (ECG). Because of concerns for hypertrophic cardiomyopathy, children with syncope meeting ECG criteria for left ventricular hypertrophy (LVH) will frequently undergo an echocardiogram. Our objectives were to determine whether Davignon criteria for ECG waves overestimate LVH in children presenting with syncope, and to study the usefulness of echocardiography in these children. We hypothesize that the Davignon criteria presently used for interpretation of ECGs overestimate LVH, resulting in unnecessary echocardiography in this clinical setting. The clinical database of The Children's Hospital of Philadelphia was evaluated from 2002 to 2012 to identify children between 9 and 16 years of age, who presented with non-exercise-induced, isolated syncope. From this group of patients, only those with clear-cut evidence of LVH (by Davignon criteria), who also underwent an echocardiogram, were selected. A total of 136 children with syncope were identified as having LVH by Davignon ECG criteria. None of these patients manifested any evidence of hypertrophic cardiomyopathy, with normal ventricular septum (average Z-score -0.68 ± 0.84), LV posterior wall (average Z-score -0.66 ± 1.18) and LV mass (average Z-score 0.52 ± 1.29). No significant correlation was found between summed RV6 plus SV1 and LV mass. Correlations between additional ECG parameters and measures of LVH by echocardiography were similarly poor. In children presenting with syncope and LVH by ECG, there was no evidence of true LVH by echocardiography. We propose that the Davignon ECG criteria for interpreting LVH in children overestimate the degree of hypertrophy in these children and the yield of echocardiography is extremely low.

Introduction. Most clinical reports on methadone rotation describe outcomes in hospitalized patients. The few studies that have included outpatients are retrospective. The aim of this study was to assess the efficacy and safety of methadone as a second-line opioid in adult patients with advanced cancer after rotation in routine clinical practice at a palliative care outpatient clinic. Patients and Methods. This was a prospective, open-label study of 145 patients whose treatment was rotated from other opioids to methadone. Informed consent was obtained in all cases. The main outcome measure was change in the variable “worst pain” at day 28. Pain and pain interference were assessed with the Brief Pain Inventory, with side effects evaluated according to the Common Terminology Criteria for Adverse Events version 3.0. Pain levels were evaluated at study entry and at days 3, 7, 9, 14, 21, and 28. Results. Rotation to methadone was performed for the following reasons: poor pain control (77.9%), opioid side effects (2.1%), or both (20%). The mean daily oral morphine equivalent dose before rotation was 193.7 mg. The median worst and average pain scores decreased significantly (p < .0001) from baseline to day 28: The median worst pain score decreased from 9 (interquartile range [IQR]: 8–10) to 6 (IQR: 3–8), and the median average pain score decreased from 6 (IQR: 5–7) to 4 (IQR: 2–5). The proportions of patients with moderate to severe worst and average pain decreased by 30.3% and 47.5%, respectively, by day 28. No increase in opioid toxicity was observed during the study. Conclusion. In outpatients with advanced cancer, rotation to methadone as a second-line opioid was efficacious and safe when using a tiered scheme with close follow-up by experienced health professionals. Implications for Practice: The results of this study, conducted prospectively under real clinical conditions, support the efficacy and safety of oral methadone as a second-line opioid in ambulatory patients with cancer. Moreover, these findings corroborate previously reported outcomes in retrospective outpatient studies and prospective studies that evaluated inpatient populations. Although more research into methadone rotation strategies is still needed, this study describes a successful tiered scheme of oral methadone rotation that was proven safe and effective during follow-up.

Osteochondritis dissecans (OCD) of the capitellum is a rare yet debilitating injury seen in young athletes. This is the first report in the literature describing fresh osteochondral allograft transplantation (FOCAT) to treat OCD of the capitellum. Nine male baseball players (mean age, 15.3; range, 14-18 years), with OCD of the capitellum were treated with FOCAT. There were 6 pitchers and 3 position players. A ligament-sparing, mini-open approach was used. A fresh femoral hemicondyle was used as a donor source. Of the 9 patients, 7 required 1 plug and 2 required 2 plugs. The average plug diameter was 11 mm (range, 8-18 mm). Five plugs were press fit, and 4 required additional fixation. Clinical outcomes were evaluated at a mean follow-up of 48.4 months (range, 11-90 months). Preoperative and postoperative outcome scores were calculated using the paired t test. The Mayo Elbow Performance score improved from an average 57.8 to 98.9 (P < .01). The Oxford Elbow Score improved from 22.4 to 44.8 (P < .01). The Disabilities of the Arm, Shoulder and Hand score improved from 35.2 to 5.4 (P < .01). The visual analog scale score improved from 7.8 to 0.5 (P < .01). The Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow score improved from 32.6 to 82.5 (P < .01). All patients returned to throwing and were still active in their sport or played at least 2 years of baseball before leaving the sport unrelated to the elbow. FOCAT for OCD of the capitellum in properly selected cases is a viable treatment with significant functional improvement and pain reduction in throwers.

SU-F-T-647: Linac-Based Stereotactic Radiosurgery (SRS) in the Treatment of Trigeminal Neuralgia: Detailed Description of SRS Procedural Technique and Reported Clinical Outcomes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pokhrel, D; Sood, S; Badkul, R

Purpose: SRS is an effective non-invasive alternative treatment modality with minimal-toxicity used to treat patients with medically/surgically refractory trigeminal neuralgia root(TNR) or those who may not tolerate surgical intervention. We present our linac-based SRS procedure for TNR treatment and simultaneously report our clinical outcomes. Methods: Twenty-eight TNR-patients treated with frame-based SRS at our institution (2009–2015) with a single-fraction point-dose of 60-80Gy to TNR were included in this IRB-approved study. Experienced neurosurgeon and radiation oncologist delineated the TNR on 1.0mm thin 3D-FIESTA-MRI that was co-registered with 0.7mm thin planning-CT. Treatment plans were generated in iPlan (BrainLAB) with a 4-mm diameter conemore » using 79 arcs with differential-weighting for Novalis-TX 6MV-SRS(1000MU/min) beam and optimized to minimize brainstem dose. Winston-Lutz test was performed before each treatment delivery with sub-millimeter isocenter accuracy. Quality assurance of frame placement was maintained by helmet-bobble-measurement before simulation-CT and before patient setup at treatment couch. OBI-CBCT scan was performed for patient setup verification without applying shifts. On clinical follow up, treatment response was assessed using Barrow Neurological Institute Pain Intensity Score(BNI-score:I–V). Results: 26/28 TNR-patients (16-males/10-females) who were treated with following single-fraction point-dose to isocenter: 80Gy(n=22),75Gy(n=1),70Gy(n=2) and 60Gy(n=1, re-treatment) were followed up. Median follow-up interval was 8.5-months (ranged:1–48.5months). Median age was 70-yr (ranged:43–93-yr). Right/left TNR ratio was 15/11. Delivered total # of average MUs was 19034±1204. Average beam-on-time: 19.0±1.3min. Brainstem max-dose and dose to 0.5cc were 13.3±2.4Gy (ranged:8.1–16.5Gy) and 3.6±0.4Gy (ranged:3.0–4.9Gy). On average, max-dose to optic-apparatus was ≤1.2Gy. Mean value of max-dose to eyes/lens was 0.26Gy/0.11Gy. Overall, 20-patients (77%) responded to treatment: 5(19%) achieved complete pain relief without medication (BNI score: I); 5(19%) had no-pain, decreased medication (BNI-score:II); 2(7.7%) had no-pain, but, continued medication (BNI-score:IIIA), and 8(30.8%) had pain that was well controlled by medication (BNI-score: IIIB). Six-patients (23.0%) did not respond to treatment (BNI-score:IV–V). Neither cranial nerve deficit nor radio-necrosis of temporal lobe was clinically observed. Conclusion: Linac-based SRS for medically/surgically refractory TNR provided an effective treatment option for pain resolution/control with very minimal if any normal tissue toxicity. Longer follow up of these patients is anticipated/needed to confirm our observations.« less

Visual inspection with acetic acid (VIA) is a simple, low-cost alternative to traditional Pap smears that could greatly benefit the amount of screening and treatment available in low-resource areas, such as rural El Salvador. The objective of this study was to train Salvadoran health providers in VIA and cryotherapy using a week-long competency course. Health providers participated in the VIA training course, which consisted of 1 half-day of didactics, followed by 4 and 1 half days of clinical training. Pretests and posttests were administered. A 1-day didactic refresher course was administered to assess the quality of services being provided. Sixty-eight nurses and physicians completed the training course. Each trainee screened approximately 120 women and performed, on average, seven cryotherapy treatments. The average trainee improved his or her score by 15% on the theoretical test and 16.7% on the image test. At the completion of the 1-day refresher, average test scores were the highest among all the courses. The final assessment was based on 41 providers. The course proved a successful tool for training healthcare providers in methods of cervical cancer screening and treatment. The course is replicable in other low-resource settings in different countries. It also provided trainees with the opportunity to adapt their clinical skills in their realistic work setting.

Salter's innominate osteotomy may predispose to anterior over-coverage of the acetabulum. Over cover or retroversion has been demonstrated to be a cause of hip pain, impingement and subsequent osteoarthritis. We reviewed the long-term follow up of seventeen skeletally mature hips in sixteen patients who had previously undergone a Salter's osteotomy in childhood. The Salter pelvic osteotomy was performed at a mean average age of 5 years and follow up at a mean average age of 20 years. Patients were assessed by clinical examination for signs of impingement, Harris Hip Score and pelvic radiograph. Acetabular version was evaluated by the relationship between anterior and posterior walls of the acetabulum using templates applied to the pelvic radiograph as described by Hefti. The median acetabular cover averaged 17 degrees of anteversion with 2 patients (12%) demonstrating retroversion, neither of whom, had signs of impingement on examination. The mean average Harris Hip Score was 85 indicating a good outcome at long-term follow-up. We believe acetabular remodelling may occur with age after Salter's innominate osteotomy and have found good results in patients after skeletal maturation. Fears of long-term anterior over-coverage and retroversion with this operation may be unfounded.

Purpose: To assess the perception of TG-142 tolerance level dose delivery failures in IMRT and the application of FMEA process to this specific aspect of IMRT. Methods: An online survey was distributed to medical physicists worldwide that briefly described 11 different failure modes (FMs) covered by basic quality assurance in step- and-shoot IMRT at or near TG-142 tolerance criteria levels. For each FM, respondents estimated the worst case H&N patient percent dose error and FMEA scores for Occurrence, Detectability, and Severity. Demographic data was also collected. Results: 181 individual and three group responses were submitted. 84% were from North America.more » Most (76%) individual respondents performed at least 80% clinical work and 92% were nationally certified. Respondent medical physics experience ranged from 2.5–45 years (average 18 years). 52% of individual respondents were at least somewhat familiar with FMEA, while 17% were not familiar. Several IMRT techniques, treatment planning systems and linear accelerator manufacturers were represented. All FMs received widely varying scores ranging from 1–10 for occurrence, at least 1–9 for detectability, and at least 1–7 for severity. Ranking FMs by RPN scores also resulted in large variability, with each FM being ranked both most risky (1st ) and least risky (11th) by different respondents. On average MLC modeling had the highest RPN scores. Individual estimated percent dose errors and severity scores positively correlated (p<0.10) for each FM as expected. No universal correlations were found between the demographic information collected and scoring, percent dose errors, or ranking. Conclusion: FMs investigated overall were evaluated as low to medium risk, with average RPNs less than 110. The ranking of 11 FMs was not agreed upon by the community. Large variability in FMEA scoring may be caused by individual interpretation and/or experience, thus reflecting the subjective nature of the FMEA tool.« less

Voting for image scoring and assessment (VISA)--theory and application of a 2 + 1 reader algorithm to improve accuracy of imaging endpoints in clinical trials.

Independent central reading or off-site reading of imaging endpoints is increasingly used in clinical trials. Clinician-reported outcomes, such as endoscopic disease activity scores, have been shown to be subject to bias and random error. Central reading attempts to limit bias and improve accuracy of the assessment, two factors that are critical to trial success. Whether one central reader is sufficient and how to best integrate the input of more than one central reader into one output measure, is currently not known.In this concept paper we develop the theoretical foundations of a reading algorithm that can achieve both objectives without jeopardizing operational efficiency We examine the role of expert versus competent reader, frame scoring of imaging as a classification task, and propose a voting algorithm (VISA: Voting for Image Scoring and Assessment) as the most appropriate solution which could also be used to operationally define imaging gold standards. We propose two image readers plus an optional third reader in cases of disagreement (2 + 1) for ordinary scoring tasks. We argue that it is critical in trials with endoscopically determined endpoints to include the score determined by the site reader, at least in endoscopy clinical trials. Juries with more than 3 readers could define a reference standard that would allow a transition from measuring reader agreement to measuring reader accuracy. We support VISA by applying concepts from engineering (triple-modular redundancy) and voting theory (Condorcet's jury theorem) and illustrate our points with examples from inflammatory bowel disease trials, specifically, the endoscopy component of the Mayo Clinic Score of ulcerative colitis disease activity. Detailed flow-diagrams (pseudo-code) are provided that can inform program design.The VISA "2 + 1" reading algorithm, based on voting, can translate individual reader scores into a final score in a fashion that is both mathematically sound (by avoiding averaging of ordinal data) and in a manner that is consistent with the scoring task at hand (based on decisions about the presence or absence of features, a subjective classification task). While the VISA 2 + 1 algorithm is currently being used in clinical trials, empirical data of its performance have not yet been reported.

To explain the role of arthroscopic release in intractable frozen shoulders. We used different questionnaires and measuring tools to understand whether arthroscopic release is the superior modality to treat patients with intractable frozen shoulders. Between 2007 and 2013, in a prospective study, we enrolled 80 patients (52 females and 28 males) with recalcitrant frozen shoulder, who underwent arthroscopic release at Ghaem Hospital, a tertiary referral center, in Mashhad, Iran. Before operation, all patients filled out the Disability of Arm, Shoulder and Hand (DASH), Constant, University of California Los Angeles (UCLA), ROWE and Visual Analogue Scale (VAS) for pain questionnaires. We measured the difference in range of motion between both the normal and the frozen shoulders in each patient. The average age of the patients was 50.8±7.1 years. In 49 patients, the right shoulder was affected and in the remaining 31 the left side was affected. Before surgery, the patients were suffering from this disease on average for 11.7±10.3 months. The average time to follow-up was 47.2±6.8 months (14 to 60 months). Diabetes mellitus (38%) and history of shoulder trauma (23%) were the most common comorbidities in our patients. We did not find any significant differences between baseline characteristics of diabetics patients with non-diabetics ones. After surgery, the average time to achieve maximum pain improvement and range of motion were 3.6±2.1 and 3.6±2 months, respectively. The VAS score, constant shoulder score, Rowe score, UCLA shoulder score, and DASH score showed significant improvement in shoulder function after surgery, and shoulder range of motion improved in all directions compared to pre-operation range of motion. According to our results, arthroscopic release of recalcitrant frozen shoulder is a valuable modality in treating this disease. This method could decrease pain and improve both subjective and objective mid-term outcomes.

To determine the clinical outcomes of intense pulsed light (IPL) therapy for the treatment of evaporative dry eye disease (DED). Multicentre cohort study. Patients with a diagnosis of meibomian gland dysfunction (MGD) and dry eye presenting to the ophthalmology clinic at either the Duke Eye Center, Durham, NC, or Matossian Eye Associates' private practice in Pennington, NJ, and Doylestown, PA. Clinical data were reviewed from 100 patients with diagnosis of MGD and DED who underwent IPL therapy from September 2012 through December 2014 at 1 of 2 centres (Duke Eye Center or Matossian Eye Associates). Demographics, clinical history, examination findings (eyelid and facial vascularity, eyelid margin edema, meibomian gland oil flow, and quality score-all graded on a scale of 0 to 4), tear break up time (TBUT), and ocular surface disease index (OSDI) scoring data were collected from each visit. On average, patients underwent 4 IPL sessions. There was significant decrease in scoring of lid margin edema (mean = -0.3; range -1.5 to 0), facial telangiectasia (mean = -0.7; range -2.5 to 0), lid margin vascularity (mean = -1.2; range -2.5 to 0), meibum viscosity (mean = -1.1; range -3 to 0), and OSDI score (mean = -9.6), all with p < 0.001. There was a significant increase in oil flow score (mean = 0.9, range -0.5 to 2) and TBUT (mean = 3.4 seconds, range -2 to 7), both p < 0.001. No significant changes in intraocular pressure or acuity were noted. There were no cases of adverse ocular effects. IPL therapy for evaporative DED is a safe procedure. The positive change in objective clinical examination findings and subjective OSDI scoring data suggest that IPL is an effective treatment for patients with evaporative DED.

The intelligence of individuals with Autism Spectrum Disorder (ASD) varies considerably. The pattern of cognitive deficits associated with ASD may differ depending on intelligence. We aimed to study the absolute and relative severity of cognitive deficits in participants with ASD in relation to IQ. A total of 274 children (M age = 12.1, 68.6% boys) participated: 30 ASD and 22 controls in the below average Intelligence Quotient (IQ) group (IQ<85), 57 ASD and 54 controls in the average IQ group (85115). Matching for age, sex, Full Scale IQ (FSIQ), Verbal IQ (VIQ), Performance IQ (PIQ) and VIQ-PIQ difference was performed. Speed and accuracy of social cognition, executive functioning, visual pattern recognition and basic processing speed were examined per domain and as a composite score. The composite score revealed a trend significant IQ by ASD interaction (significant when excluding the average IQ group). In absolute terms, participants with below average IQs performed poorest (regardless of diagnosis). However, in relative terms, above average intelligent participants with ASD showed the most substantial cognitive problems (particularly for social cognition, visual pattern recognition and verbal working memory) since this group differed significantly from the IQ-matched control group (p < .001), whereas this was not the case for below-average intelligence participants with ASD (p = .57). In relative terms, cognitive deficits appear somewhat more severe in individuals with ASD and above average IQs compared to the below average IQ patients with ASD. Even though high IQ ASD individuals enjoy a certain protection from their higher IQ, they clearly demonstrate cognitive impairments that may be targeted in clinical assessment and treatment. Conversely, even though in absolute terms ASD patients with below average IQs were clearly more impaired than ASD patients with average to above average IQs, the differences in cognitive functioning between participants with and without ASD on the lower end of the IQ spectrum were less pronounced. Clinically this may imply that cognitive assessment and training of cognitive skills in below average intelligent children with ASD may be a less fruitful endeavour. These findings tentatively suggest that intelligence may act as a moderator in the cognitive presentation of ASD, with qualitatively different cognitive processes affected in patients at the high and low end of the IQ spectrum.

The purpose of this study was to perform an objective clinical and radiological assessment of the thrust plate prosthesis (TPP). Fifty-three prostheses were evaluated clinically using the Harris hip score (HHS), visual analog scale (VAS), and radiographically before surgery, at the time of discharge, and postoperatively after on average of 8.09 (range 4.61–9.93) years. The average HHS significantly (p ≤ 0.05) improved from 48 (range 18–77) points to 95 (range 46–100) points. The VAS revealed significant (p ≤ 0.05) reduction of pain at rest and under load. Radiographic analysis showed a considerable potential for osteolysis under the thrust plate. Sixteen prostheses revealed signs of radiolucent zones. In general, there was a good clinical outcome with no major limitations in function. Radiographic changes under the thrust plate indicate an adaptation processes resulting from changed biomechanics. This study suggests that the TPP could be a good alternative in total hip replacement in younger patients. PMID:19184010

Prognostic Utility of Cell Cycle Progression Score in Men With Prostate Cancer After Primary External Beam Radiation Therapy

Freedland, Stephen J., E-mail: steve.freedland@duke.edu; Department of Surgery; Department of Pathology, Duke University School of Medicine, Durham, North Carolina

Purpose: To evaluate the prognostic utility of the cell cycle progression (CCP) score, a RNA signature based on the average expression level of 31 CCP genes, for predicting biochemical recurrence (BCR) in men with prostate cancer treated with external beam radiation therapy (EBRT) as their primary curative therapy. Methods and Materials: The CCP score was derived retrospectively from diagnostic biopsy specimens of men diagnosed with prostate cancer from 1991 to 2006 (n=141). All patients were treated with definitive EBRT; approximately half of the cohort was African American. Outcome was time from EBRT to BCR using the Phoenix definition. Median follow-upmore » for patients without BCR was 4.8 years. Association with outcome was evaluated by Cox proportional hazards survival analysis and likelihood ratio tests. Results: Of 141 patients, 19 (13%) had BCR. The median CCP score for patient samples was 0.12. In univariable analysis, CCP score significantly predicted BCR (P=.0017). The hazard ratio for BCR was 2.55 for 1-unit increase in CCP score (equivalent to a doubling of gene expression). In a multivariable analysis that included Gleason score, prostate-specific antigen, percent positive cores, and androgen deprivation therapy, the hazard ratio for CCP changed only marginally and remained significant (P=.034), indicating that CCP provides prognostic information that is not provided by standard clinical parameters. With 10-year censoring, the CCP score was associated with prostate cancer-specific mortality (P=.013). There was no evidence for interaction between CCP and any clinical variable, including ethnicity. Conclusions: Among men treated with EBRT, the CCP score significantly predicted outcome and provided greater prognostic information than was available with clinical parameters. If validated in a larger cohort, CCP score could identify high-risk men undergoing EBRT who may need more aggressive therapy.« less

Lateral unicompartmental knee arthroplasty through a lateral parapatellar approach has high early survivorship.

The literature suggests lateral unicompartmental knee arthroplasties are associated with low revision rates. However, there are fewer reports describing techniques for lateral unicompartmental arthroplasty and whether technique influences ROM and function compared to reports for medial unicompartmental arthroplasty. We report our indications for lateral unicompartmental arthroplasty, how we perform this procedure, and the subsequent Knee Society scores, ROM, and revision and reoperation rates. From a retrospective review of electronic records from 2004 through 2008, we identified 93 patients who had 100 lateral unicompartmental arthroplasties. Indications were complete lateral bone-on-bone arthrosis with a correctible deformity and maintenance of the medial joint space on varus stress radiographs or isolated lateral disease by diagnostic arthroscopy. Average age was 68 years. Seventy percent of patients were women. At followup, we obtained Knee Society scores and ROM. Minimum followup was 24 months (average, 39 months; range, 24-81 months). At followup, Knee Society scores averaged 46 for pain, 94 for clinical, and 89 for function, and ROM averaged 124°. Three patients had reoperations: one an open reduction and internal fixation for fracture at 2 years postoperatively, one an arthroscopy for a medial meniscal tear, and one a revision for pain. Based on our observations, we believe complete cartilage loss laterally and correctible deformity with maintenance of the medial joint on varus stress radiographs are reasonable indications for lateral unicompartmental arthroplasty. We recommend a lateral parapatellar approach can be utilized. The early reoperation and revision rates were low.

Most research examining the predictive validity of the Medical College Admission Test (MCAT) has focused on the relationship between MCAT scores and scores on the United States Medical Licensing Examination Step exams. This study examined whether MCAT scores predict students' unimpeded progress toward graduation (UP), which the authors defined as not withdrawing or being dismissed for academic reasons, graduating within five years of matriculation, and passing the Step 1, Step 2 Clinical Knowledge, and Step 2 Clinical Skills exams on the first attempt. Students who matriculated during 2001-2004 at 119 U.S. medical schools were included in the analyses. Logistic regression analyses were used to estimate the relationships between UP and MCAT total scores alone, undergraduate grade point averages (UGPAs) alone, and UGPAs and MCAT total scores together. All analyses were conducted at the school level and were considered together to evaluate relationships across schools. The majority of matriculants experienced UP. Together, UGPAs and MCAT total scores predicted UP well. MCAT total scores alone were a better predictor than UGPAs alone. Relationships were similar across schools; however, there was more variability across schools in the relationship between UP and UGPAs than between UP and MCAT total scores. The combination of UGPAs and MCAT total scores performs well as a predictor of UP. Both UGPAs and MCAT total scores are strong predictors of academic performance in medical school through graduation, not just the first two years. Further, these relationships generalize across medical schools.

To assess the functional and clinical results of repair of chronic tears of pectoralis major using corkscrew and sliding suture technique. In this retrospective study, we reviewed the results of pectoralis major repair in 11 chronic cases (> 6 wk) done between September 2011 and December 2014 at our institute. In all cases repair was done by same surgeon using corkscrew suture anchors and box suture sliding technique. At 6 mo, after surgery magnetic resonance imaging was done to see the integrity of the repair. Functional evaluation was done using Penn and ASES scores. Pre and postoperative Isokinetic strength was measured. Average follow-up was 48.27 ± 21.0 mo. The Wilcoxon signed rank test was used to evaluate the outcome scores. The average ASES score increased from an average of 54.63 ± 13.0 preoperatively to 95.09 ± 2.60 after surgery at their last follow-up. The average Penn score also increased from 5.72 ± 0.78, 2.81 ± 1.32 and 45.81 ± 1.72 to 9.36 ± 0.80, 8.27 ± 0.90 and 59 ± 1.34 for pain, satisfaction and function respectively. Follow up magnetic resonance imaging (MRI) (at 6 mo) showed continuity and the bulk of pectoralis major muscle in all cases. Average isokinetic strength deficiency in horizontal adduction at 60° was 13.63% ± 6.93% and at 120° was 10.18% ± 4.93% and in flexion at 60° was 10.72% ± 5.08% and at 120° was 6.63% + 3.74%. Results showed that both ASES and Penn score improved significantly (2 tailed P value = 0.0036). We could conclude from this series that pectoralis major repair even in chronic cases using 5.5 mm corkscrew anchors give excellent functional and cosmetic results. In chronic cases the repairable length of the tendon is not available and sliding suture technique allows for fixation of worn out tendomuscular junction to bone without letting cutting through the muscle.

Basic radiology interpretive skill is essential for all physicians. We developed a vertical type of radiology education, including basic radiology in the students' first clinical year and added the other 1-week or 2-week dedicated radiology rotation in the later clinical year. The objective of this study was to present a valuable radiology education to undergraduate medical students. At academic year 2014-2015, there were three different groups of the clinical-year students took a radiology rotation. All students completed the pretest of 30-image quiz at the first day of the course and the posttest of the same quiz at the last day of the course. The mean scores and the mean score changes of pretest and posttest were compared. A grade point average was used to determine the students' background characteristics. The relationships between students' background characteristics and the mean score changes were calculated. There were three groups of students including; 11 sixth-year elective students, 19 fifth-year compulsory students and 39 sixth-year compulsory students. The mean posttest score of all students were statistically significant greater than the mean pretest score (p < .001). For the students' years, time space or interest level had no significant effects on the improved score. Adding a 1-week dedicated radiology rotation to fifth- or sixth-year students after they finished the standard radiology course is beneficial to students. This type of vertical radiology curriculum is valuable and should be incorporated into formal medical school curricula. Copyright © 2017. Published by Elsevier Taiwan LLC.

Objective To determine if performance differences exist between male and female students on a 6-week obstetrics and gynecology (Ob/Gyn) clerkship and to evaluate potential variables that might underlie any observed variations. Study Design Final clerkship grades and component scores (clinical evaluations, objective structured clinical examination [OSCE], oral examination, and National Board of Medical Examiners [NBME] subject examination) from July 2007 to June 2010 were matched by student and analyzed by gender. Basic science grade point average (GPA) and initial United States Medical Licensing Exam (USMLE) Step 1 scores were used to establish students’ baseline medical knowledge. On a post-clerkship questionnaire, a subset of students reported the numbers of procedures they performed during the clerkship; students also completed online pre- and post-clerkship questionnaires reflecting their self-assessed confidence in women's health clinical skills. Results Scores were analyzed for 136 women and 220 men. Final clerkship grades were significantly higher for females than for males (89.05 vs. 87.34, p=0.0004, η 2=0.08). Specifically, females outscored males on the OSCE, oral, and NBME subject examination portions of the clerkship but not clinical evaluations. Males reported completing fewer breast examinations (p=0.001, η 2=0.14). Pre-clerkship, males were significantly less confident than females in women's health clinical skills (p<0.01) but reached similar levels upon completion of the clerkship. No gender differences were detected for basic science GPA and USMLE Step 1 scores. Conclusion Student gender is associated with final grades on an Ob/Gyn clerkship. Further research regarding these differences should be explored. PMID:24300748

Focusing public insurance programs on interceptive orthodontics (IO) may increase access for low-income children. This report presents outcomes from a randomized clinical trial (RCT) comparing IO with comprehensive orthodontics (CO) in Medicaid patients. One hundred seventy pre-adolescents with Medicaid-eligible malocclusions were randomized to IO (n = 86) followed by observation (OBS) or OBS followed by CO (n = 84). One hundred thirty-four completed the trial. Models at pre-treatment (baseline) and following ≤ 2 years of intervention and 2 years of OBS (48 mos) were scored by calibrated examiners using the Peer Assessment Rating (PAR) and Index of Complexity, Outcome and Need (ICON). Overall outcomes and clinically meaningful categorical ICON data on need/acceptability, complexity, and improvement were compared. At baseline, groups were balanced by age, gender, ethnicity, and PAR/ICON scores. Most were minorities. Most (77%) were rated as difficult-to-very difficult. Scores improved significantly for both groups, but CO more than IO (PAR, 18.6 [95%CI 15.1, 22.1] vs.10.1 [95%CI 6.7, 13.4]; ICON, 44.8 [95% CI 39.7, 49.9] vs. 35.2 [95%CI 29.7, 40.6], respectively). On average, IO is effective at reducing malocclusions in Medicaid patients, but less than CO. (ClinicalTrials.gov number CT00067379) PMID:22699670

This study evaluates the value of continuous dynamic monitoring of intracranial pressure (ICP) in patients with hypertensive intracerebral hemorrhage to predict early postoperative complications. Data from 80 patients treated in our hospital from February 2014 to February 2015 were analyzed. The patients all underwent decompressive craniectomies, and their ICP changes were monitored invasively and continuously for 1 to 7 days after surgery. The average blood loss during surgery for the group of patients was 65.3 ± 12.4 ml and the mean GCS score 8.7 ± 2.4. Cases were divided into three groups according to ICP values to compare early postoperative complications of the groups: a normal and mildly increased group (51 cases), a moderately increased group (19 cases) and a severely increased group (10 cases). To validate the analysis we first showed that comparisons among groups based on gender, age, systolic pressure, diastolic pressure, bleeding time, blood loss, operation time, craniectomy localization, and preoperative mannitol dosage yielded no statistically significant differences. In contrast, the following comparisons produced statistically significant differences: the comparison of postoperative Glasgow Coma Scale (GCS) scores showing that the lower intracranial pressure, the higher the GCS score; the postoperative rehemorrhage, cerebral edema and death ratios showing the higher the intracranial pressure, the higher the rehemorrhage ratio; the average ICP and the time to occurrence of rehemorrhage, cerebral edema or cerebral infarction, showing the relationship between the average ICP and the time to a complication. Patients with higher ICP averages suffered a complication of rehemorrhage within the first 9.6 ± 2.5 hours on average. Nevertheless, the comparison of GCS scores in those patients and the others showed no significant differences. Based on the findings, the dynamic monitoring of intracranial pressure can early and sensitively predict postoperative complications of patients with hypertensive cerebral hemorrhage, and guide the clinical intervention actively to improve the surgery outcome.

AutoIHC-scoring: a machine learning framework for automated Allred scoring of molecular expression in ER- and PR-stained breast cancer tissue.

In prognostic evaluation of breast cancer Immunohistochemical (IHC) markers namely, oestrogen receptor (ER) and progesterone receptor (PR) are widely used. The expert pathologist investigates qualitatively the stained tissue slide under microscope to provide the Allred score; which is clinically used for therapeutic decision making. Such qualitative judgment is time-consuming, tedious and more often suffers from interobserver variability. As a result, it leads to imprecise IHC score for ER and PR. To overcome this, there is an urgent need of developing a reliable and efficient IHC quantifier for high throughput decision making. In view of this, our study aims at developing an automated IHC profiler for quantitative assessment of ER and PR molecular expression from stained tissue images. We propose here to use CMYK colour space for positively and negatively stained cell extraction for proportion score. Also colour features are used for quantitative assessment of intensity scoring among the positively stained cells. Five different machine learning models namely artificial neural network, Naïve Bayes, K-nearest neighbours, decision tree and random forest are considered for learning the colour features using average red, green and blue pixel values of positively stained cell patches. Fifty cases of ER- and PR-stained tissues have been evaluated for validation with the expert pathologist's score. All five models perform adequately where random forest shows the best correlation with the expert's score (Pearson's correlation coefficient = 0.9192). In the proposed approach the average variation of diaminobenzidine (DAB) to nuclear area from the expert's score is found to be 7.58%, as compared to 27.83% for state-of-the-art ImmunoRatio software. © 2017 The Authors Journal of Microscopy © 2017 Royal Microscopical Society.

Effects of correcting for prematurity on cognitive test scores in childhood.

The American Academy of Pediatrics recommends that test scores should be corrected for prematurity up to 3 years of age, but this practice varies greatly in both clinical and research settings. The aim of this study was to contrast the effects of using chronological age and those of using corrected age on measures of cognitive outcome across childhood. A theoretical model was constructed using norms from the Bayley Scales of Infant and Toddler Development, Third Edition; the Wechsler Preschool and Primary Scale of Intelligence, Third Edition Australian; and the Wechsler Intelligence Scales for Children, Fourth Edition Australian. Baseline scores representing different levels of functioning (70, below average; 85, borderline; and 100, average) were recalculated using the normative data for ages 6 months to 16 years to account for 1, 2, 3 and 4 months of prematurity. The model created depicted the difference in standardised scores between chronological and corrected age. Compared with scores corrected for prematurity, the absolute reduction in scores using chronological age was greater for increasing degree of prematurity, younger ages at assessment and higher baseline scores and was substantial even beyond 3 years of age. However, the pattern was erratic, with considerable fluctuation evident across different ages and baseline scores. Chronological age results in a lowering of scores at all ages for preterm-born subjects that is greater in the first few years and in those born at earlier gestational ages. Whether or not to correct for prematurity depends upon the context of the assessment. © 2014 The Authors.

This study aimed to assess the preliminary clinical efficacy and feasibility of the hybrid technique for multilevel cervical myelopathy. Considering the many shortcomings of traditional treatment methods for multilevel cervical degenerative myelopathy, hybrid surgery (bi-level Bryan artificial disc [Medtronic Sofamor Danek, Memphis, TN, USA] replacement and anterior cervical discectomy and fusion) should be considered. Between March 2006 and November 2012, 108 patients (68 men and 40 women, average age 45years) underwent hybrid surgery. Based on the Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), and Odom's criteria, the clinical symptoms and neurological function before and after surgery were evaluated. Mean surgery duration was 90minutes, with average blood loss of 30mL. Mean follow-up duration was 36months. At the final follow-up, the mean JOA (± standard deviation) scores were significantly higher compared with preoperative values (15.08±1.47 versus 9.18±1.22; P<0.01); meanwhile, NDI values were markedly decreased (12.32±1.03 versus 42.68±1.83; P<0.01). Using Odom's criteria, the clinical outcomes were rated as excellent (76 patients), good (22 patients), fair (six patients), and poor (four patients). These findings indicate that the hybrid method provides an effective treatment for cervical myelopathy over three consecutive segments, ensuring a good clinical outcome.

Objective: To determine whether patients could self-report physical and mental health assessments in the waiting room and whether these assessments would be associated with modified Rankin Scale (mRS) and Quality of Life in Epilepsy (QOLIE-10) scores. Methods: We offered iPad-based surveys to consecutive adult neurology patients at check-in to collect patient-reported outcome measures (PROMs). We collected demographic and clinical data on 6,075 patients through survey or administrative claims and PROMs from participating patients. We compared demographic characteristics of participants and nonparticipants and tested associations between physical and mental health scores and mRS and QOLIE-10. Results: Of 6,075 patients seen by neurologists during the study period, 2,992 (49.3%) participated in the survey. Compared to nonparticipating patients, participating patients more often were privately insured (53.5% vs 42.7%, p < 0.01), married (51.5% vs 47.9%, p < 0.01), and seen in general neurology (nonsubspecialty) clinics (53.1% vs 46.6%, p < 0.01) and more likely to report English as their preferred language (50.1% vs 38.4%, p < 0.01). Participating patients had a mean physical health T score of 28.7 (SD 15) and mental health T score of 33 (SD 15), which were 3 and 2 SD worse than the average for the US general population, respectively. Mean T scores in every category of the mRS were different from every other category (n = 232, p < 0.01). Patient Reported Outcomes Measurement Information System-10 T scores were linearly associated with QOLIE-10 scores (n = 202, p < 0.01) Conclusions: Systematic digital collection of PROMs is feasible. Differences among survey participants and nonparticipants highlight the need to develop multilingual measurement tools that may improve collection from vulnerable populations. PMID:27815405

Peer-assisted learning (PAL) refers to a learning activity whereby students of similar academic level teach and learn from one another. Groupe de perfectionnement des habiletés cliniques (Clinical Skills Improvement Group), a student organization at Université Laval, Canada, propelled PAL into the digital era by creating a collaborative virtual patient platform. Medical interviews can be completed in pairs (a student-patient and a student-doctor) through an interactive Web-based application, which generates a score (weighted for key questions) and automated feedback. The aim of the study was to measure the pedagogical impact of the application on the score at medical interview stations at the summative preclerkship Objective Structured Clinical Examination (OSCE). We measured the use of the application (cases completed, mean score) in the 2 months preceding the OSCE. We also accessed the results of medical interview stations at the preclerkship summative OSCE. We analyzed whether using the application was associated with higher scores and/or better passing grades (≥60%) at the OSCE. Finally, we produced an online form where students could comment on their appreciation of the application. Of the 206 students completing the preclerkship summative OSCE, 170 (82.5%) were registered users on the application, completing a total of 3133 cases (18 by active user in average, 7 minutes by case in average). The appreciation questionnaire was answered online by 45 students who mentioned appreciating the intuitive, easy-to-use, and interactive design, the diversity of cases, and the automated feedback. Using the application was associated with reduced reported stress, improved scores (P=.04), and improved passing rates (P=.11) at the preclerkship summative OSCE. This study suggests that PAL can go far beyond small-group teaching, showing students' potential to create helpful pedagogical tools for their peers. ©David Bergeron, Jean-Nicolas Champagne, Wen Qi, Maxime Dion, Julie Thériault, Jean-Sébastien Renaud.

Reported are the results of a randomized controlled trial to assess the effectiveness of the WHO/UNICEF 40-hour course "Breastfeeding counselling: a training course". The course was conducted in a maternity hospital which provides care to a low-income population in a metropolitan area in São Paulo, Brazil. Health workers from 60 health units were randomly assigned to be either participants (20) or controls (40), and their breastfeeding knowledge and skills were assessed before and immediately after the course, as well as 3 months later. Immediately after the course the participants' knowledge of breastfeeding had increased significantly compared to controls. Both their clinical and counselling skills also improved significantly. When assessed 3 months later, the scores remained high with only a small decrease. The implementation of the course was also evaluated. The methods used were participatory observation, key interviews and focus group discussion. In the 33 sessions of the course, the average score was 8.43 out of 10. Scores were highest for content and methodology of the theory sessions, and lowest for "use of time", "clinical management of lactation", and "discussion of clinical practice". "Breastfeeding counselling: a training course" therefore effectively increases health workers' knowledge and their clinical and counselling skills for the support of breastfeeding. The course can be conducted adequately using the material and methodology proposed, but could be more satisfactory if the time allocated to exercises and clinical practice sessions were increased.

The assessment of dermatology undergraduates is being done through computer assisted objective structured clinical examination at our institution for the last 4 years. We attempted to compare objective structured clinical examination (OSCE) and computer assisted objective structured clinical examination (CA-OSCE) as assessment tools. To assess the relative effectiveness of CA-OSCE and OSCE as assessment tools for undergraduate dermatology trainees. Students underwent CA-OSCE as well as OSCE-based evaluation of equal weightage as an end of posting assessment. The attendance as well as the marks in both the examination formats were meticulously recorded and statistically analyzed using SPSS version 20.0. Intercooled Stata V9.0 was used to assess the reliability and internal consistency of the examinations conducted. Feedback from both students and examiners was also recorded. The mean attendance for the study group was 77% ± 12.0%. The average score on CA- OSCE and OSCE was 47.4% ± 19.8% and 53.5% ± 18%, respectively. These scores showed a mutually positive correlation, with Spearman's coefficient being 0.593. Spearman's rank correlation coefficient between attendance scores and assessment score was 0.485 for OSCE and 0.451 for CA-OSCE. The Cronbach's alpha coefficient for all the tests ranged from 0.76 to 0.87 indicating high reliability. The comparison was based on a single batch of 139 students. Such an evaluation on more students in larger number of batches over successive years could help throw more light on the subject. Computer assisted objective structured clinical examination was found to be a valid, reliable and effective format for dermatology assessment, being rated as the preferred format by examiners.

Purpose To investigate the initial clinical value of fluorine 18 ( 18 F) fluorocholine (FCH) dynamic positron emission tomography (PET)/magnetic resonance (MR) imaging by comparing its parameters with clinical-pathologic findings in patients with newly diagnosed intermediate- to high-risk prostate cancer (PCa) who plan to undergo radical prostatectomy. Materials and Methods The institutional review board approved the study protocol, and informed written consent was obtained from all subjects for this HIPAA-compliant study. Twelve men (mean age ± standard deviation, 61.7 years ± 8.4; range, 46-74 years) with untreated intermediate- to high-risk PCa characterized according to Cancer of the Prostate Risk Assessment (CAPRA) underwent preoperative FCH dynamic PET/MR imaging followed by radical prostatectomy between April and November 2015. PET/MR imaging parameters including average and maximum K1 (delivery rate constant) and standardized uptake values (SUVs) and Prostate Imaging Reporting and Data System (PI-RADS) version 2 scores were measured and compared with clinical-pathologic characteristics. For statistical analysis, the Spearman rank correlation and Mann-Whitney U tests were performed. Results Of the PET parameters, maximum SUV of primary tumors showed significant correlations with several clinical-pathologic parameters including serum prostate-specific antigen level (ρ = 0.71, P = .01), pathologic stage (ρ = 0.59, P = .043), and postsurgical CAPRA score (ρ = 0.72, P = .008). The overall PI-RADS score showed significant correlations with pathologic tumor volume (ρ = 0.81, P < .001), percentage of tumor cells with Gleason scores greater than 3 (ρ = 0.59, P = .02), and postsurgical CAPRA score (ρ = 0.58, P = .046). The high-risk postsurgical CAPRA score patient group had a significantly higher maximum SUV than did the intermediate-risk group. Combined PET and MR imaging showed improved sensitivity (88%) for prediction of pathologic extraprostatic extension compared with that with MR imaging (50%) and PET (75%) performed separately. Conclusion Maximum SUVs and PI-RADS scores from FCH PET/MR imaging show good correlation with clinical-pathologic characteristics, such as postsurgical CAPRA score, which are related to prognosis in patients with newly diagnosed intermediate- to high-risk PCa. © RSNA, 2016 Online supplemental material is available for this article.

Non-operative treatment with immobilization is the gold-standard for paediatric clavicular fractures. Purpose of this study is to evaluate functional outcomes and efficacy of non-operative treatment of clavicular fractures in a succession of 131 children. Between 2006 and 2012, we treated non-surgically 131 children for a clavicular fracture. All fractures have been classified according to Robinson classification. Clavicle shortening, range of movements and muscular strength through the Medical Research Council (MRC) scale were evaluated. To assess the outcomes, QuickDASH questionnaire, dividing the sample in 3 age-related group, was administered. The average follow-up was 26 months (8-84 months). Clavicle shortening at the time of injury occurred in 18 cases. All fractures reached union. Average time to union was 34 days. Mean time return to activity was 12.6 weeks. No cases of nonunion or delayed union were reported. Complications occurred in 21 cases. A shortening persisted in 2 cases. Only one patient had a slight functional restriction. Average QuickDASH score was 6.2±1.1 (range 4.3-9.4). All patients recovered to a MRC score of 5, except for one patient with a score of 4. Best QuickDASH scores were observed in the group aged under 8 years and in non-comminuted and lateral third fractures of the clavicle. Observing results, clavicle fractures have a satisfactory clinical healing as shown by the good scores at QuickDASH and MRC scale. Younger children under 8 years can achieve the best results with a conservative treatment in terms of bone healing and activity level.

To assess interpersonal skills of internationally educated nurses (IEN) while interacting with standardized patients. Participants included 52 IEN at two community hospitals in the southwestern region of the USA. Standardized patients were used to create patient-nurse encounter. Seventeen items in four domains ("skills in interviewing and collecting information"; "skills in counseling and delivering information"; "rapport"; and "personal manner") in an Interpersonal Skills (IPS) instrument were measured by a Likert scale 1-4 with 4 indicating the best performance. The average composite score per domain and scores of the 17 items were compared across the domains. On 10 of the 17 items, the nurses received scores under 3. Counseling with an average score of 2.10 and closure with an average score of 2.44 in domain 2, small talk with an average score of 2.06 in domain 3, and physical exam with average score of 2.21 in domain 4 were below 2.5. The average composite score of domain 1 was 3.54, significantly higher than those of domains 2-4 (2.77, 2.81, and 2.71, respectively). Age was moderately related to the average score per domain with every 10 year increase in age resulting in a 0.1 increase in the average score. Sex and country of origin showed mixed results. The interpersonal skills of IEN in three of the four domains need improvement. Well-designed educational programs may facilitate the improvement, especially in areas of small talk, counseling, closure, and physical exam. Future research should examine relationships between the IPS and demographics factors. © 2013 The Authors. Japan Journal of Nursing Science © 2013 Japan Academy of Nursing Science.

The aim of this study is to show the results of scaphotrapeziotrapezoid (STT) joint osteoarthritis treatment performing resurfacing arthroplasty with scaphoid anchorage. An observational, descriptive and retrospective study was performed. Ten patients with isolated STT joint osteoarthritis were studied between 2013 and 2015. The mean follow-up time was 26months. Clinical results, functional and subjective scores were reviewed. The patients were satisfied, achieving an average of 2.1 (0-3) on the VAS score and 16 (2 to 28) in the DASH questionnaire, and returning to work in the first three months post-surgery. Recovery of range of motion compared to the contralateral wrist was 96% in extension, 95% in flexion, 87% in ulnar deviation and 91% in radial deviation. The average handgrip strength of the wrist was 95% and pinch strength was 95% compared to the contralateral side. There were no intraoperative complications or alterations in postoperative carpal alignment. Resurfacing arthroplasty is proposed as a good and novel alternative in treating isolated SST joint arthritis. Achieving the correct balance between the strength and mobility of the wrist, without causing carpal destabilisation, is important to obtain satisfactory clinical and functional results.

Gardner, Michael J; Boraiah, Sreevathsa; Helfet, David L; Lorich, Dean G

2008-02-01

Displaced and unstable fractures of the proximal humerus are notoriously difficult to manage. Successful surgical treatment requires finding the appropriate balance between adequate exposure for reduction and rigid fixation and minimizing soft tissue dissection. The anterolateral acromial approach was developed to allow less invasive treatment of proximal humerus fractures. The plane of the avascular anterior deltoid raphe is utilized, and the axillary nerve is identified and protected. Anterior dissection near the critical blood supply is avoided, substantial muscle retraction is minimized, and the lateral plating zone is directly accessed. Over a 4-year period, 52 patients with acute displaced fractures of the proximal humerus were treated with the anterolateral acromial approach and either a locking plate or an intramedullary nail. Twenty-three patients were evaluated clinically at a minimum follow-up of 1 year (average, 28 months) by clinical examination for range of motion and nerve function and a QuickDASH score. There were no axillary nerve deficits postoperatively related to the approach, and the average QuickDASH score was 25.2 (0, best; 100, worst). This approach allowed direct access to the lateral fracture planes for fracture reduction and plate placement or safe nail and interlocking screw placement.

Osteochondral lesions of the ankle are a common injury after ankle sprains, especially in young and active patients. The Osteochondral Autograft Transfer System (OATS) is the only 1-step surgical technique designed to replace the entire osteochondral unit. This study was conducted to evaluate the long-term clinical and radiographic outcomes of the OATS procedure for the talus and compare the results of patients who have had prior surgical interventions with patients for whom OATS represents the primary surgical treatment. Case series; Level of evidence, 4. The authors retrospectively analyzed 26 talus OATS procedures (25 patients) with an average follow-up of 84 months (range, 53-124 months); 9 patients had OATS as a second surgical intervention. The patients completed the American Orthopaedic Foot & Ankle Society (AOFAS) and Tegner scores plus the visual analog scale (VAS) preoperatively and at follow-up. Magnetic resonance imaging examinations were conducted on a 1.5-T whole-body magnet that assessed transplant congruency, adjacent surface of the talus, the corresponding distal tibia, and joint effusion. The authors found significant increases for the AOFAS score (50 to 78 points, P < .01) and the Tegner score (3.1 to 3.7, P < .05) and a significant decrease for the VAS (7.8 to 1.5, P < .01) from preoperative to postoperative. Patients with normal integration or minor incongruity of the transplant on magnetic resonance imaging (81%) had significantly better AOFAS scores (P = .03). Other magnetic resonance imaging criteria did not predict clinical results. Patients for whom OATS represented a second procedure had significantly worse clinical AOFAS and Tegner scores plus a higher VAS. Long-term clinical and magnetic resonance imaging results after osteochondral transplantation are good and patients significantly benefit from this surgery. Magnetic resonance imaging should not be a routine control but appears to be indicated when clinical symptoms persist after osteochondral transplantation.

Preclinical simulator training has the potential to decrease endoscopic procedure time and patient discomfort. This study aims to characterize the learning curve of endoscopic novices in a part-task simulator and propose a threshold score for advancement to initial clinical cases. Twenty novices with no prior endoscopic experience underwent repeated endoscopic simulator sessions using the part-task simulator. Simulator scores were collected; their inverse was averaged and fit to an exponential curve. The incremental improvement after each session was calculated. Plateau was defined as the session after which incremental improvement in simulator score model was less than 5%. Additionally, all participants filled out questionnaires regarding simulator experience after sessions 1, 5, 10, 15, and 20. A visual analog scale and NASA task load index were used to assess levels of comfort and demand. Twenty novices underwent 400 simulator sessions. Mean simulator scores at sessions 1, 5, 10, 15, and 20 were 78.5 ± 5.95, 176.5 ± 17.7, 275.55 ± 23.56, 347 ± 26.49, and 441.11 ± 38.14. The best fit exponential model was [time/score] = 26.1 × [session #] -0.615 ; r 2  = 0.99. This corresponded to an incremental improvement in score of 35% after the first session, 22% after the second, 16% after the third and so on. Incremental improvement dropped below 5% after the 12th session corresponding to the predicted score of 265. Simulator training was related to higher comfort maneuvering an endoscope and increased readiness for supervised clinical endoscopy, both plateauing between sessions 10 and 15. Mental demand, physical demand, and frustration levels decreased with increased simulator training. Preclinical training using an endoscopic part-task simulator appears to increase comfort level and decrease mental and physical demand associated with endoscopy. Based on a rigorous model, we recommend that novices complete a minimum of 12 training sessions and obtain a simulator score of at least 265 to be best prepared for clinical endoscopy.

Anterior tension wiring using Kirschner wires (K-wires) is still considered the standard treatment for patella fractures, despite its high complication rate. The objective of this prospective clinical study was to evaluate intra- and perioperative complications as well as the clinical outcome of patients with patella fracture treated with a new developed bilateral, polyaxial, fixed-angle 2.7mm patella plate. Between 2011 and 2014 all patients with a patella fracture were included in this prospective study and treated with a fixed-angle patella plate. Avulsion fractures of the inferior or superior pole of the patella were excluded. All fractures were classified according to the AO/OTA fracture classification. During a twelve-month follow up period all intra- and postoperative complications were recorded as well as the time until fracture healing. One year postoperatively the Lysholm Score, the pre- and postoperative Tegner Score, the Hospital for Special Surgery Knee Score (HSS), the Turba Score, the Oxford Knee Score, the Knee injury and Osteoarthritis Outcome Score (KOOS), the Bostman Score and the Iowa Knee Score were surveyed. Altogether, 20 patella fractures in 19 patients were included in this prospective study. The most frequent type of fracture, n=10, was a simple transverse patella fracture (C1), followed by 7 comminuted patella fractures (C3) and 3 T-shaped patella fractures (C2). During the 12-month follow up period two patients treated with the patella plate had a complication. In one patient a superficial wound infection occurred, which was treated successfully with hardware removal and in one patient a fracture dislocation due to an implant failure occurred. X-rays demonstrated complete bony healing in all fractures on average 3.2 months postoperatively. All knee scores showed good to excellent clinical results one year postoperatively. The results of this first clinical study indicate that the fixed-angle patella plate is an effective and safe treatment option for patella fractures with a short operative learning curve. The treatment of communited patella fractures (C3) with a fixed-angle patella plate should be well-considered to avoid distending the indication and biomechanical properties.

Purpose: To evaluate the diagnostic value of various unenhanced head CT protocols and predicate acceptable radiation dose level for head CT exam. Methods: Our retrospective analysis included 3 groups, 20 patients per group, who underwent clinical routine unenhanced adult head CT examination. All exams were performed axially with 120 kVp. Three protocols, 380 mAs without iterative reconstruction and automAs, 340 mAs with iterative reconstruction without automAs, 340 mAs with iterative reconstruction and automAs, were applied on each group patients respectively. The images were reconstructed with H30, J30 for brain window and H60, J70 for bone window. Images acquired with threemore » protocols were randomized and blindly reviewed by three radiologists. A 5 point scale was used to rate each exam The percentage of exam score above 3 and average scores of each protocol were calculated for each reviewer and tissue types. Results: For protocols without automAs, the average scores of bone window with iterative reconstruction were higher than those without iterative reconstruction for each reviewer although the radiation dose was 10 percentage lower. 100 percentage exams were scored 3 or higher and the average scores were above 4 for both brain and bone reconstructions. The CTDIvols are 64.4 and 57.8 mGy of 380 and 340 mAs, respectively. With automAs, the radiation dose varied with head size, resulting in 47.5 mGy average CTDIvol between 39.5 and 56.5 mGy. 93 and 98 percentage exams were scored great than 3 for brain and bone windows, respectively. The diagnostic confidence level and image quality of exams with AutomAs were less than those without AutomAs for each reviewer. Conclusion: According to these results, the mAs was reduced to 300 with automAs OFF for head CT exam. The radiation dose was 20 percentage lower than the original protocol and the CTDIvol was reduced to 51.2 mGy.« less

Objective To determine the effects of a semi-customized experimental cervical pillow on symptomatic adults with chronic neck pain (with and without headache) during a four week study. Design A randomized controlled trial. Sample size Thirty-six adults were recruited for the trial, and randomly assigned to experimental or non-experimental groups of 17 and 19 participants respectively. Subjects Adults with chronic biomechanical neck pain who were recruited from the Canadian Memorial Chiropractic College (CMCC) Walk-in Clinic. Outcome measures Subjective findings were assessed using a mail-in self-report daily pain diary, and the CMCC Neck Disability Index (NDI). Statistical analysis Using repeated measure analysis of variance weekly NDI scores, average weekly AM and PM pain scores between the experimental and non-experimental groups were compared throughout the study. Results The experimental group had statistically significant lower NDI scores (p < 0.05) than the non-experimental group. The average weekly AM scores were lower and statistically significant (p < 0.05) in the experimental group. The PM scores in the experimental group were lower but not statistically significant than the other group. Conclusions The study results show that compared to conventional pillows, this experimental semi-customized cervical pillow was effective in reducing low-level neck pain intensity, especially in the morning following its use in a 4 week long study.

The purpose of this study was to evaluate the clinical outcomes of osteochondral autograft transplantation (OAT) for juvenile osteochondritis dissecans (JOCD) lesions of the knee, especially time to return to sports. Twelve knee JOCD lesions with OCD grade 3 and 4 categorised by magnetic resonance imaging (MRI) were treated with OAT. Nine male and two female skeletally immature patients averaging 13.7 years old were included. The OCD lesions were assessed arthroscopically and then fixed in situ using multiple osteochondral plugs harvested under fluoroscopy from the distal femoral condyle without damaging the physis. International Cartilage Repair Society (ICRS) score and Lysholm score were assessed pre- and postoperatively. After a mean follow-up of 26.2 ± 15.1 months, the International Knee Documentation Committee (IKDC) subjective score significantly improved (p < 0.01). According to the IKDC score, objective assessment showed that ten of 12 (83 %) had excellent results (score: A) after OAT and significantly improved (p < 0.01). Based on ICRS criteria, results were satisfactory in all patients. No patients experienced complications at the graft harvest site. All patients returned to their previous level of athletic activity at an average of 5.7 months after the surgery. OAT for JOCD of the knee provided satisfactory results in all patients at a mean follow-up of 26.2 months.

The PREVAIL (Prevention of VTE [venous thromboembolism] after acute ischemic stroke with LMWH [low-molecular-weight heparin] and UFH [unfractionated heparin]) study demonstrated a 43% VTE risk reduction with enoxaparin versus UFH in patients with acute ischemic stroke (AIS). A 1% rate of symptomatic intracranial and major extracranial hemorrhage was observed in both groups. To determine the economic impact, from a hospital perspective, of enoxaparin versus UFH for VTE prophylaxis after AIS. A decision-analytic model was constructed and hospital-based costs analyzed using clinical information from PREVAIL. Total hospital costs were calculated based on mean costs in the Premier™ database and from wholesalers acquisition data. Costs were also compared in patients with severe stroke (National Institutes of Health Stroke Scale [NIHSS] score ≥14) and less severe stroke (NIHSS score <14). The average cost per patient due to VTE or bleeding events was lower with enoxaparin versus UFH ($422 vs $662, respectively; net savings $240). The average anticoagulant cost, including drug-administration cost per patient, was lower with UFH versus enoxaparin ($259 vs $360, respectively; net savings $101). However, when both clinical events and drug-acquisition costs were considered, the total hospital cost was lower with enoxaparin versus UFH ($782 vs $922, respectively; savings $140). Hospital cost-savings were greatest ($287) in patients with NIHSS scores ≥14. The higher drug cost of enoxaparin was offset by the reduction in clinical events as compared to the use of UFH for VTE prophylaxis after an AIS, particularly in patients with severe stroke.

Eliciting patient preferences within the context of shared decision making has been advocated for colorectal cancer screening. Risk stratification for advanced colorectal neoplasia (ACN) might facilitate more effective shared decision making when selecting an appropriate screening option. Our objective was to develop and validate a clinical index for estimating the probability of ACN at screening colonoscopy. We conducted a cross-sectional analysis of 3,543 asymptomatic, mostly average-risk patients 50-79 years of age undergoing screening colonoscopy at two urban safety net hospitals. Predictors of ACN were identified using multiple logistic regression. Model performance was internally validated using bootstrapping methods. The final index consisted of five independent predictors of risk (age, smoking, alcohol intake, height, and a combined sex/race/ethnicity variable). Smoking was the strongest predictor (net reclassification improvement (NRI), 8.4%) and height the weakest (NRI, 1.5%). Using a simplified weighted scoring system based on 0.5 increments of the adjusted odds ratio, the risk of ACN ranged from 3.2% (95% confidence interval (CI), 2.6-3.9) for the low-risk group (score ≤2) to 8.6% (95% CI, 7.4-9.7) for the intermediate/high-risk group (score 3-11). The model had moderate to good overall discrimination (C-statistic, 0.69; 95% CI, 0.66-0.72) and good calibration (P=0.73-0.93). A simple 5-item risk index based on readily available clinical data accurately stratifies average-risk patients into low- and intermediate/high-risk categories for ACN at screening colonoscopy. Uptake into clinical practice could facilitate more effective shared decision-making for CRC screening, particularly in situations where patient and provider test preferences differ.

Background Physicians’ recommendations affect patients’ treatment choices. However, most research relies on physicians’ or patients’ retrospective reports of recommendations, which offer a limited perspective and have limitations such as recall bias. Objective To develop a reliable and valid method to measure the strength of physician recommendations using direct observation of clinical encounters. Methods Clinical encounters (n = 257) were recorded as part of a larger study of prostate cancer decision making. We used an iterative process to create the 5-point Physician Recommendation Coding System (PhyReCS). To determine reliability, research assistants double-coded 50 transcripts. To establish content validity, we used one-way ANOVAs to determine whether relative treatment recommendation scores differed as a function of which treatment patients received. To establish concurrent validity, we examined whether patients’ perceived treatment recommendations matched our coded recommendations. Results The PhyReCS was highly reliable (Krippendorf’s alpha =. 89, 95% CI [.86, .91]). The average relative treatment recommendation score for each treatment was higher for individuals who received that particular treatment. For example, the average relative surgery recommendation score was higher for individuals who received surgery versus radiation (mean difference = .98, SE = .18, p < .001) or active surveillance (mean difference = 1.10, SE = .14, p < .001). Patients’ perceived recommendations matched coded recommendations 81% of the time. Conclusion The PhyReCS is a reliable and valid way to capture the strength of physician recommendations. We believe that the PhyReCS would be helpful for other researchers who wish to study physician recommendations, an important part of patient decision making. PMID:27343015

Per-oral endoscopic myotomy (POEM) has become an accepted treatment for patients with achalasia. Despite its excellent efficacy rate of greater than 80%, a small percentage of patients remain symptomatic after the procedure. Limited data exist as to the best management for recurrence of symptoms after POEM. We present the first international, multicenter experience on the efficacy and safety of a repeat POEM in the management of achalasia. Patients who underwent a redo POEM from 15 centers in 9 countries were included in a dedicated registry. Technical success was defined as successful completion of a second myotomy. Clinical success was defined as an Eckardt score of less than or equal to 3 after the second myotomy. Adverse events including anesthesia-related, operative, and postoperative adverse events were recorded. Forty-six patients were included in the study. The average age was 49.3 ± 16.78 years. Twenty (45%) patients were male. The mean pre-redo-POEM Eckardt score was 4.3 ± 2.48. Technical success was achieved in 46 (100%) patients. Clinical success was achieved in 41 patients (85%). The average post-POEM Eckardt score was 1.64 ± 1.67, with a significant difference of 2.58 (P < .00001). Eight patients (17%) had adverse events consisting of procedural bleeding, all managed endoscopically. There were no deaths. No POEMs were aborted or required surgical conversion or assistance. For patients with persistent symptoms after POEM, repeat POEM appears to be an efficacious and safe technique. Further randomized trials comparing redo POEM versus Heller should be considered.

2017-09-01

Clinical outcomes of terrible triad injuries (TTIs) of the elbow are historically poor. To date, it is still debatable whether the coronoid needs to be fixed and if so, how and in which sequence. Between 2010 and 2013, 13 patients were treated surgically for acute TTIs of the elbow at a Tertiary Level 1 Trauma Centre by a single surgeon, using a standardized protocol, which included coronoid-brachialis complex fixation via pull-through trans-osseous sutures, radial head fixation or prosthetic replacement and a repair of the lateral ulnar collateral ligament. Repair of the medial collateral ligament (MCL) was done if valgus-stress test demonstrated persistent instability. Patients were then followed-up with clinical and radiological evaluation by the senior author until fracture union and elbow range of motion reached a plateau. Outcomes measured were range of motion, DASH scores and MEPS, as well as surgical complications. Intraoperative stability was achieved in all 13 cases, MCL repair was required in 3 cases and application of external fixation was not required in any case. Patients were followed-up for an average length of 27.7 months and the minimum follow-up period was 12 months. The average age of patients was 46.4 years (range 35-79 years old) at the time of trauma. This included eight Regan-Morrey Type I and five Regan-Morrey Type II coronoid fractures, with ten Mason Type I/II and three Mason Type III radial head fractures. The average arc of ulno-humeral motion was 105.0° (range 80°-135°). The average flexion contracture was 15.0° (range 0°-40°). The average supination-pronation arc was 114.9° (range 0°-180°). The average MEPS was 85 of 100 (range 45-100) and the average DASH score was 21.2 of 100 (range 1.7-61.2). A single case of radio-ulnar synostosis, heterotropic ossification and two cases of recurrent elbow instability were noted. The coronoid-first surgical approach, using a suture-lasso fixation method, has technical benefits for us and showed good clinical success in our series. This is important with postero-medial rotatory instability being common in our series of TTIs. We emphasize not to miss a TTI in an apparently isolated low Mason class radial head fracture.

Cadaveric studies have shown that deficiency of the posterior horn of the medial meniscus (PHMM) increases strain on the anterior cruciate ligament (ACL) graft. However, its influence on the clinical and radiological outcome after ACL reconstruction is less discussed and hence evaluated in this study. This study included 77 cases of ACL reconstruction with a minimum 18-month follow-up. Of the 77 cases, 41 patients with intact menisci were compared clinically and radiologically with 36 patients with an injury to the PHMM that required various grades of meniscectomy. The knees were evaluated using subjective International Knee Documentation Committee (IKDC) score and Orthopadische Arbeitsgruppe Knie (OAK) score. Cases with intact menisci showed better stability (p=0.004) at an average of 44.51 months after surgery. No significant differences were noted in the overall OAK score, subjective IKDC score, and functional OAK score (p=0.082, p=0.526, and p=0.363, respectively). The incidence of radiological osteoarthrosis was significantly higher in the posterior horn deficient knees (p=0.022). The tendency toward relatively higher objective instability and increased incidence of osteoarthrosis in the group with absent posterior horn reinforces its importance as a secondary stabiliser of the knee.

This study examined demographic characteristics, social competence, and behavior problems in clinic-referred children with gender identity problems in Toronto, Canada (N = 358), and Utrecht, The Netherlands (N = 130). The Toronto sample was, on average, about a year younger than the Utrecht sample at referral, had a higher percentage of boys, had a higher mean IQ, and was less likely to be living with both parents. On the Child Behavior Checklist (CBCL), both groups showed, on average, clinical range scores in both social competence and behavior problems. A CBCL-derived measure of poor peer relations showed that boys in both clinics had worse ratings than did the girls. A multiple regression analysis showed that poor peer relations were the strongest predictor of behavior problems in both samples. This study-the first cross-national, cross-clinic comparative analysis of children with gender identity disorder-found far more similarities than differences in both social competence and behavior problems. The most salient demographic difference was age at referral. Cross-national differences in factors that might influence referral patterns are discussed.

Diabetes quality management in Dutch care groups and outpatient clinics: a cross-sectional study

PubMed Central

2014-01-01

Background In recent years, most Dutch general practitioners started working under the umbrella of diabetes care groups, responsible for the organisation and coordination of diabetes care. The quality management of these new organisations receives growing interest, although its association with quality of diabetes care is yet unclear. The best way to measure quality management is unknown and it has not yet been studied at the level of outpatient clinics or care groups. We aimed to assess quality management of type 2 diabetes care in care groups and outpatient clinics. Results Quality management was measured with online questionnaires, containing six domains (see below). They were divided into 28 subdomains, with 59 (care groups) and 57 (outpatient clinics) questions respectively. The mean score of the domains reflects the overall score (0-100%) of an organisation. Two quality managers of all Dutch care groups and outpatient clinics were invited to fill out the questionnaire. Sixty care groups (response rate 61.9%) showed a mean score of 59.6% (CI 57.1-62.1%). The average score in 52 outpatient clinics (response rate 50.0%) was 61.9% (CI 57.5-66.8%). Mean scores on the six domains for care groups and outpatient clinics respectively were: ‘organisation of care’ 71.9% (CI 68.8-74.9%), 76.8% (CI 72.8-80.7%); ‘multidisciplinary teamwork’ 67.1% (CI 62.4-71.9%), 71.5% (CI 65.3-77.8%); ‘patient centeredness’ 46.7% (CI 42.6-50.7%), 62.5% (CI 57.7-67.2%); ‘performance management’ 63.3% (CI 61.2-65.3%), 50.9% (CI 44.2-57.5%); ‘quality improvement policy’ 52.6% (CI 49.2-56.1%), 50.9% (CI 44.6-57.3%); and ‘management strategies’ 56.0% (CI 51.4-60.7%), 59.0% (CI 52.8-65.2%). On subdomains, care groups scored highest on ‘care program’ (83.3%) and ‘measured outcomes’ (98.3%) and lowest on ‘patient safety’ (15.1%) and ‘patient involvement’ (17.7%). Outpatient clinics scored high on the presence of a ‘diabetic foot team’ (81.6%) and the support in ‘self-management’ (81.0%) and low on ‘patient involvement’ (26.8%) and ‘inspection of medical file’ (28.0%). Conclusions This nationwide assessment reveals that the level of quality management in diabetes care varies between several subdomains in both diabetes care groups and outpatient clinics.

The Nd:YAG laser has been considered the gold standard of treatment for leg veins, but pain and side effects have fueled physicians to use treatment alternatives. To compare the clinical efficacy of the long-pulsed 1064-nm Nd:YAG laser with KTP laser irradiation in the treatment of leg telangiectasia. A series of 16 patients with size-matched superficial telangiectases of the lower extremities were randomly assigned to receive three consecutive monthly treatments with the long-pulsed 1064-nm Nd:YAG on one leg and 532-nm KTP laser irradiation on the other. For the 16 patients who completed the study, 64 leg vein sites were treated. Average clinical improvement scores were 1.94 and 1.25 for the KTP laser-treated leg and 3.38 and 3.50 for the Nd:YAG laser-treated leg with thin (≤ 1 mm) and large (1-3 mm) vessels, respectively. After the third treatment session, average improvement scores of 2.44, 1.31 and 3.75, 3.23 were given for the KTP and Nd:YAG laser-treated sides, respectively. Both the 1064-nm Nd:YAG and KTP lasers are effective in the treatment of lower extremity telangiectases. However, the KTP laser has very low efficacy with vessels larger than 1 mm and should not be elected when treating such vessels.

Measuring coding intensity in the Medicare Advantage program.

Kronick, Richard; Welch, W Pete

In 2004, Medicare implemented a system of paying Medicare Advantage (MA) plans that gave them greater incentive than fee-for-service (FFS) providers to report diagnoses. Risk scores for all Medicare beneficiaries 2004-2013 and Medicare Current Beneficiary Survey (MCBS) data, 2006-2011. Change in average risk score for all enrollees and for stayers (beneficiaries who were in either FFS or MA for two consecutive years). Prevalence rates by Hierarchical Condition Category (HCC). Each year the average MA risk score increased faster than the average FFS score. Using the risk adjustment model in place in 2004, the average MA score as a ratio of the average FFS score would have increased from 90% in 2004 to 109% in 2013. Using the model partially implemented in 2014, the ratio would have increased from 88% to 102%. The increase in relative MA scores appears to largely reflect changes in diagnostic coding, not real increases in the morbidity of MA enrollees. In survey-based data for 2006-2011, the MA-FFS ratio of risk scores remained roughly constant at 96%. Intensity of coding varies widely by contract, with some contracts coding very similarly to FFS and others coding much more intensely than the MA average. Underpinning this relative growth in scores is particularly rapid relative growth in a subset of HCCs. Medicare has taken significant steps to mitigate the effects of coding intensity in MA, including implementing a 3.4% coding intensity adjustment in 2010 and revising the risk adjustment model in 2013 and 2014. Given the continuous relative increase in the average MA risk score, further policy changes will likely be necessary.

A fully automated multi-modal computer aided diagnosis approach to coronary calcium scoring of MSCT images

2012-03-01

Inter- and intra- observer variability is a problem often faced when an expert or observer is tasked with assessing the severity of a disease. This issue is keenly felt in coronary calcium scoring of patients suffering from atherosclerosis where in clinical practice, the observer must identify firstly the presence, followed by the location of candidate calcified plaques found within the coronary arteries that may prevent oxygenated blood flow to the heart muscle. However, it can be difficult for a human observer to differentiate calcified plaques that are located in the coronary arteries from those found in surrounding anatomy such as the mitral valve or pericardium. In addition to the benefits to scoring accuracy, the use of fast, low dose multi-slice CT imaging to perform the cardiac scan is capable of acquiring the entire heart within a single breath hold. Thus exposing the patient to lower radiation dose, which for a progressive disease such as atherosclerosis where multiple scans may be required, is beneficial to their health. Presented here is a fully automated method for calcium scoring using both the traditional Agatston method, as well as the volume scoring method. Elimination of the unwanted regions of the cardiac image slices such as lungs, ribs, and vertebrae is carried out using adaptive heart isolation. Such regions cannot contain calcified plaques but can be of a similar intensity and their removal will aid detection. Removal of both the ascending and descending aortas, as they contain clinical insignificant plaques, is necessary before the final calcium scores are calculated and examined against ground truth scores of three averaged expert observer results. The results presented here are intended to show the feasibility and requirement for an automated scoring method to reduce the subjectivity and reproducibility error inherent with manual clinical calcium scoring.

To explore the clinical effect of antero-medial incision of knee joint in treating intercondylar fracture of femur. From September 2012 to March 2015, 24 patients with intercondylar fracture of femur were selected, including 17 males and 7 females, aged from 20 to 65 years old with an average of(38.3±9.5) years old. Among them, 12 cases were caused by traffic accident, 8 cases were caused by falling injury and 4 cases were caused by falling down. All patients were closed fractures. The time from injury to hospital was from 30 min to 8 h with an average of(2.2±0.3) h. According to AO classification, 4 cases were type B1, 3 type B2, 2 type B3, 5 type C1, 6 type C2 and 4 type C3. All patients were treated with antero-medial incision of knee joint. Operative time, blood loss and postoperative complications were observed and recovery of keen function was evaluated by Kolmert scoring. All patients were followed-up from 6 to 12 months with average of (9.0±1.7) months. Operative time ranged from 50 to 90 min with an average of (70.0±8.2) min; blood loss ranged from 90 to 400 ml with an average of (180±36) ml; negative pressure flow was from 30 to 90 ml, with an average of (50.0±7.1) ml. All fracture were healed at stage I without loosening of internal fixator, fracture nonunion, and deep vein thrombosis. According to Kolmert scoring, 16 patients got excellent result, 5 patients good and 3 fair. Antero-medial incision of knee joint in treating intercondylar fracture of femur, which has advantages of good fracture reduction, less injury of soft tissue and simple operation, could obtain good clinical results.

In our previous phase II studies we treated 112 patients with malignant brain tumors with 2-mg/kg Photofrin i.v. and intra-operative cavitary PDT. We concluded that PDT was safe in patients with newly diagnosed or recurrent supratentorial malignant gliomas. Pathology, performance grade and light dose were significantly related to survival time. In selected patients when an adequate light dose was used survival time improved. The surgical mortality rate was less than 3%. [spie 2000] We have initiated two randomized prospective trials - the first, to determine if the addition of PDT to standard therapy [surgery, radiation and/or chemotherapy] prolongs the survival of patients with newly diagnosed malignant astrocytic tumors; and the second, to determine whether high light dose PDT [120 J/cm2] is superior to low light dose PDT [40 J/cm2] in patients with recurrent malignant astrocytic tumors. To date, 158 patients have been recruited - 72 to the newly diagnosed malignant glioma study and 86 to the recurrent glioma study. In the recurrent glioma study we compared the pre-operative KS and elements of the neurological examination [speech function, visual fields, cognitive function, sensory examination and gait] to the post-operative examinations at hospital discharge. The means were compared by paired student-t test. The KS in 86 of 88 patients with recurrent gliomas were assessable. The mean [s.d.] preoperative and post-operative KS were 82+/- 14 and 79+/- 17, respectively [p=0.003]. The mean decline in KS, although statistically significant, was small and of no clinical importance. The median Karnofsky score changed from 90 to 80. The KS improved in 8 patients; their post-operative average length of stay (alos) was =9.7 days. There was no change in 47 [alos=8.3], a decline of 10 points in 24 [aloc=13.4] and declined by more than 10 points in 7 [alos=23.3]. Three of these 7 patients who had a decline of >10 points improved in follow-up but did not reach their preoperative KS. The data were not available in 2. Elements of the preoperative and discharge neurological examination were assigned a score and compared by a paired t-test. There was a statistically insignificant improvement in the neurological score. A small but statistically significant decline in Karnofsky score was identified post-operatively in these recurrent tumor patients. Their hospital average length of stay increased with declining Karnofsky score. These prospective clinical observations confirmed our previous conclusion that brain tumor PDT was safe. The clinical studies are supported in part by grant CA 43892 awarded by DHHS/NIH/NCI.

Background: Asthma is a major public health problem that affects millions of children worldwide, and exacerbations account for most of its morbidity and costs. Primary-care providers lack efficient tools to identify children at high risk for exacerbations. We aimed to construct a clinical score to help providers to identify such children. Methods: Our main outcome was severe asthma exacerbation, which was defined as any hospitalization, urgent visit, or systemic steroid course for asthma in the previous year, in children. A clinical score, consisting of a checklist questionnaire made up of 17 yes-no questions regarding asthma symptoms, use of medications and health-care services, and history, was built and validated in a cross-sectional study of Costa Rican children with asthma. It was then evaluated using data from the Childhood Asthma Management Program (CAMP), a longitudinal trial cohort of North American children. Results: Compared with children at average risk for an exacerbation in the Costa Rican validation set, the odds of an exacerbation among children in the low-risk (OR, 0.2; 95% CI, 0.1-0.4) and high-risk (OR, 5.4; 95% CI, 1.5-19.2) score categories were significantly reduced and increased, respectively. In CAMP, the hazard ratios for an exacerbation after 1-year follow-up in the low-risk and high-risk groups were 0.6 (95% CI, 0.5-0.7) and 1.9 (95% CI, 1.4-2.4), respectively, with similar results at 2 years. Conclusions: The proposed Asthma Exacerbation Clinical Score is simple to use and effective at identifying children at high and low risk for asthma exacerbations. The tool can easily be used in primary-care settings. PMID:20472862

The Voice Handicap Index-10 (VHI-10) is commonly used to measure patients' perception of vocal handicap. Clinical consensus has previously defined clinically meaningful improvement as a decrease ≥5. This study determines the minimal clinically important difference (MCID) for VHI-10 in patients with unilateral vocal fold paralysis (UVFP) using anchor-based methodology. Prospective cohort questionnaire analysis. Two hundred eighty-one UVFP patients completed the VHI-10 on two consecutive visits (within 3 months). At the follow-up visit, patients answered an 11-point Global Rating of Change Questionnaire (GRCQ) scored from -5 to +5. Relationship between the GRCQ and change in VHI-10 was quantified using analysis of variance, and MCID for the VHI-10 was determined using receiver operating characteristic (ROC) curve analysis. Overall mean VHI-10 change was -3.71 (standard deviation [SD] = 8.89) and mean GRCQ was 1.37 (SD = 2.51). Average interval between measurements was 1.73 months (SD = 0.83). Mean changes in VHI-10 scores were -7.45, -0.53, and +4.40 for patients whose GRCQ scores indicated improvement, no change, and worsening, respectively. Differences between mean scores were statistically significant (P < .001). Area under the ROC curve was 0.80, demonstrating the classification accuracy of VHI-10 change scores. A VHI-10 change of -4 was determined to be the optimal threshold that discriminated between improvement and no improvement (sensitivity and specificity 0.62 and 0.88, respectively). The MCID for improvement in VHI-10 in UVFP patients is a decrease of 4. This information improves understanding of patients' response to treatment and allows comparison between different treatments. Future research should determine MCID for VHI-10 across all voice disorders. 4. Laryngoscope, 128:1419-1424, 2018. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

ABSTRACT Objective: To compare the application time and the capacity of the nomograms to predict the success of Guy's Stone Score (GSS), S.T.O.N.E. Nephrolithometry (STONE) and Clinical Research Office of the Endourological Society nephrolithometric nomogram (CROES) of percutaneous nephrolithotomy (PCNL), evaluating the most efficient one for clinical use. Materials and Methods: We studied 48 patients who underwent PCNL by the same surgeon between 2010 and 2011. We calculated GSS, STONE and CROES based on pre-operative non-contrast computed tomography (CT) images and clinical data. A single observer, blinded to the outcomes, reviewed all images and assigned scores. We compared the application time of each nomogram. We used an analysis of variance for repeated measures and multiple comparisons by the Tukey test. We compared the area under the ROC curve (AUC) of the three nomograms two by two to determine the most predictive scoring system. Results: The immediate success rate was 66.7% and complications occurred in 16.7% of cases. The average operative time was 122 minutes. Mean application time was significantly lower for the GSS (27.5 seconds) when compared to 300.6 seconds for STONE and 213.4 seconds for CROES (p<0.001). There was no significant difference among the GSS (AUC=0.653), STONE (AUC=0.563) and CROES (AUC=0.641) in the ability to predict immediate success of PCNL. Conclusions: All three nomograms showed similar ability to predict success of PCNL, however the GSS was the quickest to be applied, what is an important issue for routine clinical use when counseling patients who are candidates to PCNL.

Purpose Optimal analgesia in ambulatory urology patients still remains a challenge. The aim of this study was to examine if the pre-emptive use of intravenous tramadol can reduce pain after ureteroscopic lithotripsy in patients diagnosed with unilateral ureteral stones. Materials and Methods This prospective pilot cohort study included 74 patients diagnosed with unilateral ureteral stones who underwent ureteroscopic lithotripsy under general anesthesia in the Urology Clinic at the Clinical Center of Serbia from March to June 2012. All patients were randomly allocated to two groups: one group (38 patients) received intravenous infusion of tramadol 100 mg in 500 mL 0.9%NaCl one hour before the procedure, while the other group (36 patients) received 500 mL 0.9%NaCl at the same time. Visual analogue scale (VAS) scores were recorded once prior to surgery and two times after the surgery (1 h and 6 h, respectively). The patients were prescribed additional postoperative analgesia (diclofenac 75 mg i.m.) when required. Pre-emptive effects of tramadol were assessed measuring pain scores, VAS1 and VAS2, intraoperative fentanyl consumption, and postoperative analgesic requirement. Results The average VAS1 score in the tramadol group was significantly lower than that in the non-tramadol group. The difference in average VAS2 score values between the two groups was not statistically significant; however, there were more patients who experienced severe pain in the non-tramadol group (p<0.01). The number of patients that required postoperative analgesia was not statistically different between the groups. Conclusion Pre-emptive tramadol did reduce early postoperative pain. The patients who received pre-emptive tramadol were less likely to experience severe post-operative pain. PMID:25048508

Linear growth rate (LGR) is the most commonly employed trigger for definitive intervention in patients with renal masses managed with an initial period of active surveillance (AS). Using our institutional cohort, we explored the association between tumor anatomic complexity at presentation and LGR in patients managed with AS. Enhancing renal masses managed expectantly for at least 6 months were included for analysis. The association between Nephrometry Score and LGR was assessed using generalized estimating equations, adjusting for the age, Charlson score, race, sex, and initial tumor size. Overall, 346 patients (401 masses) met the inclusion criteria (18% ≥ cT1b), with a median follow-up of 37 months (range: 6-169). Of these, 44% patients showed progression to definitive intervention with a median duration of 27 months (range: 6-130). On comparing patients managed expectantly to those requiring intervention, no difference was seen in median tumor size at presentation (2.2 vs. 2.2 cm), whereas significant differences in median age (74 vs. 65 y, P < 0.001), Charlson comorbidity score (3 vs. 2, P<0.001), and average LGR (0.23 vs. 0.49 cm/y, P < 0.001) were observed between groups. Following adjustment, for each 1-point increase in Nephrometry Score sum, the average tumor LGR increased by 0.037 cm/y (P = 0.002). Of the entire cohort, 6 patients (1.7%) showed progression to metastatic disease. The demonstrated association between anatomic tumor complexity at presentation and renal masses of LGR of clinical stage 1 under AS may afford a clinically useful cue to tailor individual patient radiographic surveillance schedules and warrants further evaluation.

Pedersen, Ken Steen; Toft, Nils

2011-03-01

The objective of the current study was to evaluate intra- and inter-observer agreement using a descriptive classification scale with four categories, descriptive text and pictures for assessment of consistency in faecal samples from pigs post weaning. The four consistency categories were score one=firm and shaped, score two=soft and shaped, score three=loose and score four=watery. Five observers from the same veterinary practice examined 100 faecal samples using the scale with four categories. Four of the observers examined the 100 faecal samples twice within the same day. Within observers the difference in proportions for the individual consistency categories between two examinations was on average 0.04 (range: 0-0.10). The mean intra-observer agreement was 0.82 (range: 0.72-0.91) with a mean kappa value of 0.76 (range: 0.61-0.88). For inter-observer agreement overall kappa was 0.64. For the 10 pair-wise comparisons the mean inter-observer agreement was 0.73 (range: 0.61-0.90) with a mean kappa value of 0.64 (range: 0.48-0.87). The difference in proportions for the individual consistency categories was on average 0.08 (range: 0-0.17). In conclusion, the agreement observed for the descriptive classification scale with four categories, descriptive text and pictures may be categorized as a substantial to almost perfect intra-observer agreement and a moderate to almost perfect inter-observer agreement. However, more objective measures than clinical scales may still be needed to improve intra- and inter-observer agreement in research studies. Copyright © 2010 Elsevier B.V. All rights reserved.

Effective patient communication is correlated with better health outcomes and patient satisfaction, but is challenging to train, particularly with difficult clinical scenarios such as loss of sight. In this pilot study, we evaluated the use of simulated patient encounters with actors to train optometric students. Students were recorded during encounters with actors and assigned to an enrichment group performing five interactions with instructor feedback (n = 6) or a no-enrichment group performing two interactions without feedback (n = 4). Student performance on first and last encounters was scored with (1) subjective rating of performance change using a visual analog scale (anchors: much worse/much better), (2) yes/no response: Would you recommend this doctor to a friend/relative?, and (3) average score on questions from the American Board of Internal Medicine (ABIM) assessment of doctor communication skills. Three clinical instructors, masked to student group assignments and the order of patient encounters they viewed, provided scores in addition to self-evaluation by students and patient-actors. Using the visual analog scale, students who received enrichment were rated more improved than the no-enrichment group by masked examiners (+18 vs. -11% p = 0.04) and self-evaluation (+79 vs. +27% p = 0.009), but not by actors (+31 vs. +43%). The proportion of students recommended significantly increased following enrichment for masked examiners (61% vs. 94%; p < 0.001), but not actors (100 vs. 83%). Average ABIM assessment scores were not significantly different by any rating group: masked instructors, actors, or self-ratings. The findings of this study suggest five simulated patient encounters with feedback result in measurable improvement in student-patient communication skills as rated by masked examiners.

Identifying the influence of gender on motivation and engagement levels in student physiotherapists.

There is an increasing focus in higher education on the role of learner characteristics and their influence on academic performance. Educators are interested in how students engage with learning activities as they progress through the curriculum. A previous study highlighted gender effects in academic performance in student physiotherapists, despite comparable entry scores. The aim of this study was to determine variation in student motivation and engagement, across the four year levels of the physiotherapy program at The University of Notre Dame Australia while considering gender and age. A cross-sectional design was adopted surveying 233 students utilising the Motivation and Engagement Scale - University/College (MES-UC), to review motivational thoughts and behaviours influencing learning. RESULTS identified gender effects with males having on average significantly lower scores for planning, task management and persistence; and higher scores for disengagement from their studies. Females displayed higher average scores for anxiety particularly in their first year and final clinical year. RESULTS were consistent with gender effects noted in academic performance throughout the program for previous student cohorts. The application of the MES-UC early in course would highlight to educators the areas where intervention can be targeted. Early individualized intervention is recommended to address learner characteristics influencing performance.

This work is a part of our ongoing study aimed at comparing the topology of anatomical branching structures with the underlying image texture. Detection of regions of interest (ROIs) in clinical breast images serves as the first step in development of an automated system for image analysis and breast cancer diagnosis. In this paper, we have investigated machine learning approaches for the task of identifying ROIs with visible breast ductal trees in a given galactographic image. Specifically, we have developed boosting based framework using the AdaBoost algorithm in combination with Haar wavelet features for the ROI detection. Twenty-eight clinical galactograms with expert annotated ROIs were used for training. Positive samples were generated by resampling near the annotated ROIs, and negative samples were generated randomly by image decomposition. Each detected ROI candidate was given a confidences core. Candidate ROIs with spatial overlap were merged and their confidence scores combined. We have compared three strategies for elimination of false positives. The strategies differed in their approach to combining confidence scores by summation, averaging, or selecting the maximum score.. The strategies were compared based upon the spatial overlap with annotated ROIs. Using a 4-fold cross-validation with the annotated clinical galactographic images, the summation strategy showed the best performance with 75% detection rate. When combining the top two candidates, the selection of maximum score showed the best performance with 96% detection rate.

Purpose HMG-CoA reductase inhibitors (statins) are extensively used in treating hypercholesterolemia. The statins available in Malaysia include atorvastatin, lovastatin, pravastatin, rosuvastatin, simvastatin, and fluvastatin. Over the years, they have accumulated in the National Drug Formulary; hence, the need for review. Effective selection of the best drugs to remain in the formulary can become complex due to the multiple drug attributes involved, and is made worse by the limited time and resources available. The multiattribute scoring tool (MAST) systematizes the evaluation of the drug attributes to facilitate the drug selection process. In this study, a MAST framework was developed to rank the statins based on their utilities or benefits. Methods Published literature on multicriteria decision analysis (MCDA) were studied and five sessions of expert group discussions were conducted to build the MAST framework and to review the evidence. The attributes identified and selected for analysis were efficacy (clinical efficacy, clinical endpoints), safety (drug interactions, serious side effects and documentation), drug applicability (drug strength/formulation, indications, dose frequency, side effects, food–drug interactions, and dose adjustments), and cost. The average weights assigned by the members for efficacy, safety, drug applicability and cost were 32.6%, 26.2%, 24.1%, and 17.1%, respectively. The utility values of the attributes were scored based on the published evidence or/and agreements during the group discussions. The attribute scores were added up to provide the total utility score. Results Using the MAST, the six statins under review were successfully scored and ranked. Atorvastatin scored the highest total utility score (TUS) of 84.48, followed by simvastatin (83.11). Atorvastatin and simvastatin scored consistently high, even before drug costs were included. The low scores on the side effects for atorvastatin were compensated for by the higher scores on the clinical endpoints resulting in a higher TUS for atorvastatin. Fluvastatin recorded the lowest TUS. Conclusion The multiattribute scoring tool was successfully applied to organize decision variables in reviewing statins for the formulary. Based on the TUS, atorvastatin is recommended to remain in the formulary and be considered as first-line in the treatment of hypercholesterolemia. PMID:24353428

Asthma is the most common chronic disease among adolescents. This study assessed the quality of life (QOL) related to health in adolescents with asthma and its determining factors (demographic, socioeconomic, and clinical). We also separately evaluated each of the parameters that comprised the asthma control classification. This was an observational, cross-sectional study of 114 adolescents who had doctor-diagnosed asthma. QOL was assessed using a version of the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) that was adapted and validated for Brazil, and higher scores indicated a better QOL. The level of asthma control was assessed using the rating system proposed by the Global Initiative for Asthma, and sociodemographic factors were evaluated. When the averages of the PAQLQ domains and overall scores were compared to the potentially explanatory variables, significantly lower average PAQLQ scores were obtained for individuals with an inadequate level of asthma control (p < 0.001). Of the control components, daytime symptoms, nighttime symptoms, and limited physical activity were related to QOL. However, the use of the β2 agonist and the peak flow functional parameter were not related to QOL. The level of asthma control was related to QOL, but this association manifested mainly in the subjective control domains, such as nighttime and daytime symptoms and physical activity limitations. The objective domain for control classification, represented by pulmonary function, was not an independent predictor or determinant of the QOL of adolescent asthma patients.

Taking OSCE examiner training on the road: reaching the masses.

Reid, Katharine; Smallwood, David; Collins, Margo; Sutherland, Ruth; Dodds, Agnes

To ensure the rigour of objective structured clinical examinations (OSCEs) in assessing medical students, medical school educators must educate examiners with a view to standardising examiner assessment behaviour. Delivering OSCE examiner training is a necessary yet challenging part of the OSCE process. A novel approach to implementing training for current and potential OSCE examiners was trialled by delivering large-group education sessions at major teaching hospitals. The 'OSCE Roadshow' comprised a short training session delivered in the context of teaching hospital 'Grand Rounds' to current and potential OSCE examiners. The training was developed to educate clinicians about OSCE processes, clarify the examiners' role and required behaviours, and to review marking guides and mark allocation in an effort to standardise OSCE processes and encourage consistency in examiner marking behaviour. A short exercise allowed participants to practise marking a mock OSCE to investigate examiner marking behaviour after the training. OSCE Roadshows at four metropolitan and one rural teaching hospital were well received and well attended by 171 clinicians across six sessions. Unexpectedly, medical students also attended in large numbers ( n= 220). After training, participants' average scores for the mock OSCE clustered closely around the ideal score of 28 (out of 40), and the average scores did not differ according to the levels of clinical experience. The OSCE Roadshow demonstrated the potential of brief familiarisation training in reaching large numbers of current and potential OSCE examiners in a time and cost-effective manner to promote standardisation of OSCE processes.

Delivering OSCE examiner training is a necessary yet challenging part of the OSCE process. A novel approach to implementing training for current and potential OSCE examiners was trialled by delivering large-group education sessions at major teaching hospitals. Methods The 'OSCE Roadshow' comprised a short training session delivered in the context of teaching hospital 'Grand Rounds' to current and potential OSCE examiners. The training was developed to educate clinicians about OSCE processes, clarify the examiners' role and required behaviours, and to review marking guides and mark allocation in an effort to standardise OSCE processes and encourage consistency in examiner marking behaviour. A short exercise allowed participants to practise marking a mock OSCE to investigate examiner marking behaviour after the training. Results OSCE Roadshows at four metropolitan and one rural teaching hospital were well received and well attended by 171 clinicians across six sessions. Unexpectedly, medical students also attended in large numbers (n=220). After training, participants' average scores for the mock OSCE clustered closely around the ideal score of 28 (out of 40), and the average scores did not differ according to the levels of clinical experience. Conclusion The OSCE Roadshow demonstrated the potential of brief familiarisation training in reaching large numbers of current and potential OSCE examiners in a time and cost-effective manner to promote standardisation of OSCE processes.

Objective. To assess the impact of a debate exercise on self-reported evidence of student learning in literature evaluation, evidence-based decision making, and oral presentation. Methods. Third-year pharmacy students in a required infectious disease therapeutics course participated in a modified debate exercise that included a reading assignment and readiness assessment tests consistent with team-based learning (TBL) pedagogy. Peer and faculty assessment of student learning was accomplished with a standardized rubric. A pre- and post-debate survey was used to assess self-reported perceptions of abilities to perform skills outlined by the learning objectives. Results. The average individual readiness assessment score was 93.5% and all teams scored 100% on their team readiness assessments. Overall student performance on the debates was also high with an average score of 88.2% prior to extra credit points. Of the 95 students, 88 completed both pre- and post-surveys (93% participation rate). All learning objectives were associated with a statistically significant difference between pre- and post-debate surveys with the majority of students reporting an improvement in self-perceived abilities. Approximately two-thirds of students enjoyed the debates exercise and believed it improved their ability to make and defend clinical decisions. Conclusion. A debate format adapted to the pedagogy of TBL was well-received by students, documented high achievement in assessment of skills, and improved students’ self-reported perceptions of abilities to evaluate the literature, develop evidence-based clinical decisions, and deliver an effective oral presentation.

This research aims to develop a gait index for use in the pediatric clinic as well as research, that quantifies gait deviation in 18-22 month-old children: the Toddle Temporal-spatial Deviation Index (Toddle TDI). 81 preterm children (≤32 weeks) with very-low-birth-weights (≤1500g) and 42 full-term TD children aged 18-22 months, adjusted for prematurity, walked on a pressure-sensitive mat. Preterm children were administered the Bayley Scales of Infant Development-3rd Edition (BSID-III). Principle component analysis of TD children's temporal-spatial gait parameters quantified raw gait deviation from typical, normalized to an average(standard deviation) Toddle TDI score of 100(10), and calculated for all participants. The Toddle TDI was significantly lower for preterm versus TD children (86 vs. 100, p=0.003), and lower in preterm children with <85 vs. ≥85 BSID-III motor composite scores (66 vs. 89, p=0.004). The Toddle TDI, which by design plateaus at typical average (BSID-III gross motor 8-12), correlated with BSID-III gross motor (r=0.60, p<0.001) and not fine motor (r=0.08, p=0.65) in preterm children with gross motor scores ≤8, suggesting sensitivity to gross motor development. The Toddle TDI demonstrated sensitivity and specificity to gross motor function in very-low-birth-weight preterm children aged 18-22 months, and has been potential as an easily-administered, revealing clinical gait metric.

To determine if coding and billing acumen improves after a single directed educational training session. Case-control series. Fourteen otolaryngology practitioners including trainees each completed two clinical scenarios before and after a directed educational session covering basic skills and common mistakes in otolaryngology billing and coding. Ten practitioners had never coded before; while, four regularly billed and coded in a clinical setting. Individuals with no previous billing experience had a mean score of 54% (median 55%) before the educational session which was significantly lower than that of the experienced billers who averaged 82% (median 83%, p=0.002). After the educational billing and coding session, the inexperienced billers mean score improved to 62% (median, 67%) which was still statistically lower than that of the experienced billers who averaged 76% (median 75%, p=0.039). The inexperienced billers demonstrated a significant improvement in their total score after the intervention (P=0.019); however, the change observed in experienced billers before and after the educational intervention was not significant (P=0.469). Billing and coding skill was improved after a single directed education session. Residents, who are not responsible for regular billing and coding, were found to have the greatest improvement in skill. However, providers who regularly bill and code had no significant improvement after this session. These data suggest that a single 90min billing and coding education session is effective in preparing those with limited experience to competently bill and code. Copyright © 2012.

The aim of this article was to explore retrospectively the Takei dynamometer as a valid and reliable outcome measure tool for hand and wrist pathology in the Great Britain amateur boxing squad between 2010 and 2014. Longitudinal retrospective injury surveillance of the Great Britain boxing squad was performed from 2010 to 2014. The location, region affected, description, and duration of each injury were recorded by the team doctor and team physiotherapists. For each significant injury, we recorded hand grip scores using the Takei handheld dynamometer and compared the scores with baseline measures. At the hand, fractures and dislocations were highly detected with an average difference of 40.2% ( P < .05) when comparing postinjury to baseline measures. At the wrist, carpometacarpal and carpal joint injuries were highly detected with an average difference of 32.6% ( P < .05). Other injuries provided varied results. In the absence of pathology, up to 15% difference between left and right scores can be considered normal with a predominance observed below 10%. A difference of 20% can be indicative of a form of pathology, although pathologies can also be present with lower difference or no apparent changes. A difference of >20% should be highly considered for significant pathology. The Takei dynamometer is a valid and reliable outcome measure tool for hand and wrist pathologies in boxing. Our study highlights the importance of appropriate clinical tools to guide injury management in this sport.

Optimal outpatient anticoagulation management requires a systematic and coordinated approach. Extensive evidence regarding the benefits of pharmacist-managed anticoagulation services has been reported in the literature. The quality and outcomes associated with pharmacist-managed anticoagulation clinics under collaborative practice agreements in the Middle East have rarely been reported. The first pharmacist-managed ambulatory anticoagulation clinic in Qatar was launched at Al-Wakrah Hospital in March 2013. The objectives of this study were to: (i) describe the practice model of the clinic, (ii) evaluate the quality of the clinic [i.e. the time in therapeutic range (TTR)] and the clinical outcomes (i.e. the efficacy and safety), and (iii) determine the patients' satisfaction and overall quality of life (QoL). Clinical outcome data were collected through a retrospective chart review of all patients managed from March 2013 to October 2014 at the pharmacist-managed anticoagulation clinic. Furthermore, the patient-oriented outcomes data were prospectively collected using the 24-item Duke Anticoagulation Satisfaction Scale (DASS). Each item was assessed using a 7-point Likert-type scale on which lower scores indicated better QoL and greater satisfaction. The clinical outcome data analyses included 119 patients who were enrolled at the clinic during the 19-month study period. The mean number of international normalized ratio (INR) tests/month was 65 ± 9, the average testing frequency was 2·7 ± 1·6 weeks, and the average %TTR was 76·8 ± 22·9%. There was one major bleeding event (0·67%/year), 12 minor bleeding events (8%/year) and two thromboembolic events (1·35%/year) recorded during the study period. Of the 119 patients, 50 participated in the satisfaction and QoL survey. The median (IQR) total QoL score of these subjects was 63 (48) (minimum-maximum achievable score: 24-168). Seventy-six per cent of the patients indicated 'a lot to very much' in terms of their overall satisfaction with the anticoagulation treatment. The participants who were naïve to anticoagulation treatment reported a significantly greater satisfaction and better QoL than the experienced patients [58 (44) vs. 82 (59); P = 0·009]. These findings provide early evidence that the patients who were managed at a pharmacy-based anticoagulation clinic in an evolving healthcare system experienced optimal anticoagulation management. © 2016 John Wiley & Sons Ltd.

To compare clinical outcomes of locking plate for proximal humeral fracture whether application of inferomedial screws. From January 2012 to July 2013, 46 patients with proximal humeral fracture underwent locking plates were retrospectively analyzed. There were 25 males and 21 females aged from 29 to 80 years old with an average of 55.1 years old. Among them, 25 patients were treated with inferomedial screws (support group), including 13 males and 12 females aged from 38 to 80 years old with an average of (55.8 ± 11.8) years old; 8 cases were part two fracture,10 cases were part three fracture and 7 cases were part four fracture according to Neer classification. Twenty-one patients were treated without inferomedial screws (non-support group), including 12 males and 9 females aged from 29 to 79 years old with an average of (54.2 ± 14.8)years old; 6 cases were part two fracture, 9 cases were part three fracture and 6 cases were part four fracture according to Neer classification. Operative time, fracture healing time and complications were observed and compared, Neer scoring of shoulder joint were used to evaluate clinical effect. All patients were followed up from 12 to 41 months with an average of 15.6 months. Operative time and fracture healing time in support group was (1.6 ± 0.4) h and (3.0 ± 0.6) months, and (1.5 ± 0.4) h and (3.1 ± 0.6) months in non-support group, while there was no statistical difference in operative time and fracture healing time between two groups. There was significant differences in Neer score between support group (89.7± 4.9) and non-support group (83.1 ± 7.1). No complication occurred in support group,while 4 cases occurred complications in non-support group. Locking plate with inferomedial screws for proximal humeral fracture has advantages of stable fixation, less complications, quick recovery of function and satisfied clinical effect.

To assess the usefulness of the Montreal Cognitive Assessment (MoCA) total score (MoCA-TS) and Memory Index Score (MoCA-MIS) in predicting conversion to Alzheimer's disease (AD) in individuals with mild cognitive impairment (MCI). Retrospective chart review. Community-based memory clinic. Individuals meeting Petersen's MCI criteria (N = 165). Baseline MoCA scores at MCI diagnosis were collected from charts of eligible individuals with MCI, and MoCA-TS, MoCA-MIS, and a cognitive domain index score were calculated to assess their prognostic value in predicting conversion to AD. One hundred fourteen participants progressed to AD (MCI-AD), and 51 did not (nonconverters; MCI-NC); 90.5% of participants with MCI with a MoCA-TS less than 20/30 and a MoCA-MIS less than 7/15 at baseline converted to AD within the average follow-up period of 18 months, compared with 52.7% of participants with MCI above the cutoffs on both scores. Individuals with multiple-domain amnestic MCI had the highest AD conversion rates (73.9%). Identifying individuals with MCI at high risk of conversion to AD is important clinically and for selecting appropriate subjects for therapeutic trials. Individuals with MCI with a low MoCA-TS and a low newly devised memory index score (MoCA-MIS) are at greater risk of short-term conversion to AD. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Determine correlation between complications and stage of the disease and their impact on quality of life in patients with different types of ileal urinary derivation after radical cystectomy, and upon estimation of acquired results, to suggest the most acceptable type of urinary diversion. In five year period a prospective clinical study was performed on 106 patients, to whom a radical cystectomy was performed due to bladder cancer. Patients were divided into two groups, 66 patients with ileal conduit derivation and 40 patients with orthotopic derivation, whereby in each group a comparison between reflux and anti-reflux technique of orthotopic bladder was made. All patients from both groups filled the Sickness Impact Profile score six months after the operation. All patients had CT urography or Intravenous urography performed, as well as standard laboratory, vitamin B12 blood values, in order to evaluate early (ileus or subileus, wound dehiscence, bladder fistula, rupture of orthotopic bladder, urine extravazation) and late complications (VUR, urethral stricture, ureter stenosis, metabolic acidosis, mineral dis-balance, hypovitaminosis of vitamin B12, increased resorption of bone calcium, urinary infection, kidney damage, relapse of primary disease), so as disease stage and it's impact on quality of life. From gained results we observe that each category of SIP score correlates with different rate of correlation with the type of operation, group, T, N, and R grade, except work category. Average value of SIP score rises depending on the type of operation and T stage. It is notable that there is no difference in T1 stage, no matter the type of operation. So the average value of SIP score in T1 stage for conduit was 20.3, for Abol-Enein and Ghoneim 17.25 and Hautmann 18.75 respectively. Average value of SIP score in T2 stage for conduit was 31, for Abol-Enein and Ghoneim 19.1 and Hautmann 17.8. Average value of SIP score in T3 stage for conduit was 38.03, for Abol-Enein and Ghoneim 18.75 and Hautmann 19.5. SIP score for T4 was present only in patients with conduit performed and average value od SIP score was 40.42. There is a high level of correlation of late complications and psychosocial and physical dimension with their parameters, while for an independent dimension of correlation is not significant. Early complications have insignificant correlation in all categories of SIP score. Upon analyzing quality of life and morbidity, significant advantage is given to orthotopic derivations, especially Hautmann derivation with Chimney modification, unless there are no absolute contraindications for performing this type of operation. Factors which mostly influence quality of life are cancer stage, type of derivation, late complications and patient age. SIP score, as a well validated questionnaire, are applicable in this kind of research.

Patient-reported outcome (PRO) measures complement traditional biomedical outcome measures. The purpose of this study was to evaluate the use of PRO measures including health-related quality of life (HRQoL) questionnaires as a measurement of efficacy and the frequency of inclusion of economic variables related to direct and indirect costs in the design of clinical trials and phase IV observational studies. Moreover, for the trials quality score were measured, and if there were any relationship between the quality study design score and the PRO inclusion. Retrospective observational study of the clinical trials and phase IV observational studies approved by a Clinical Research Ethics Committee (2008-2010). We gathered data concerning general aspects including medical specialty, pathology, methodological quality based on Jadad scale (0-5), inclusion of PRO and economic variables. For clinical trials including HRQoL measurements, we analysed the type of questionnaire in use. Where there were no HRQoL measurements, we analysed if their inclusion would have been proper or not. A total of 70 protocols (59 CTs and 11 phase IV observational studies) were analysed; 37 (52.8%) included PRO measures, and 3 protocols (4.3%) used them as a primary endpoint. Data analysis by therapeutic area showed that PRO measures were most commonly studied in the fields of endocrinology, neurology, digestive diseases, and cardiology. The average quality score for the trials was 2.8. The trials with more PRO inclusion in their end points had a significantly higher quality score. Only 13 (22%) clinical trials and 2 (18.2%) phase IV observational studies included economic variables. The emergence of economic variables in clinical trials and phase IV observational studies evaluated was low, however, more than half of the revised protocols have included PRO measures, reflecting the importance of these parameters in the assessment of the effectiveness of drug treatments, although its use is still not systematic.

Numerous studies have indicated an association between spirituality and health outcomes. However, little information is available about interventions that have been shown to enhance spiritual health and decrease stress. This study examined the effects of a spiritual learning program (SLP) on nursing student-perceived spiritual health and clinical practice stress. A convenience sample of nursing students currently enrolled at a nursing school in northern Taiwan were recruited to participate in this quasiexperimental study as participants to experimental and control groups via simple random sampling. Results from a spiritual health scale and a perceived clinical practice stress scale, together with the score for clinical nursing practice, were compared between the groups. Baseline data were collected from all participants. The experimental group participated in 8 weeks of 50-minute per week SLP, which included lectures, discussion, reflection, and spiritual practices. A second data set was collected from all participants after the intervention. A third data set was collected after all participants had performed 4 weeks of nursing clinical practice. Participants were all women. Average age was 19.4 years (SD = 1.3 years). Generalized estimating equation analysis showed SLP to have a significant short-term effect on improving the total score for spiritual health (p < .01). Significantly greater improvement in clinical practice stress scores was also seen in the experimental group as compared with the control group (all p < .05). The experimental group obtained a higher score of the final clinical practice than the control group (t = 3.771, p < .001). The SLP may encourage participants to see stressors as meaningful events that are connected to individual life purposes. The program developed in this study may be used to improve spiritual health and reduce stress in nursing students' clinical practice. This SLP may be referenced when designing similar spirituality-related courses and applied to nursing student counseling.

Objective. To develop and implement an elective course on vitamins and minerals and their usefulness as dietary supplements. Design. A 2-credit-hour elective course designed to provide students with the most up-to-date basic and clinical science information on vitamins and minerals was developed and implemented in the doctor of pharmacy (PharmD) curriculum. In addition to classroom lectures, an active-learning component was incorporated in the course in the form of group discussion. Assessment. Student learning was demonstrated by examination scores. Performance on pre- and post-course surveys administered in 2011 demonstrated a significant increase in students' knowledge of the basic and clinical science aspects of vitamins and minerals, with average scores increasing from 61% to 86%. At the end of the semester, students completed a standard course evaluation. Conclusion. An elective course on vitamin and mineral supplements was well received by pharmacy students and helped them to acquire knowledge and competence in patient counseling regarding safe, appropriate, effective, and economical use of these products.

Within clinical discourse, social history (SH) includes important information about substance use (alcohol, drug, and nicotine use) as key risk factors for disease, disability, and mortality. In this study, we developed and evaluated a natural language processing (NLP) system for automated detection of substance use statements and extraction of substance use attributes (e.g., temporal and status) based on Stanford Typed Dependencies. The developed NLP system leveraged linguistic resources and domain knowledge from a multi-site social history study, Propbank and the MiPACQ corpus. The system attained F-scores of 89.8, 84.6 and 89.4 respectively for alcohol, drug, and nicotine use statement detection, as well as average F-scores of 82.1, 90.3, 80.8, 88.7, 96.6, and 74.5 respectively for extraction of attributes. Our results suggest that NLP systems can achieve good performance when augmented with linguistic resources and domain knowledge when applied to a wide breadth of substance use free text clinical notes.

Previous studies have reached conflicting conclusions about the associations between service and academic achievement and service and primary care specialty choice. This study examines the associations between service at a student-run clinic and academic achievement and primary care specialty choice. Retrospective review of medical student service and statistical analysis of grade point average (GPA), Step 1 and Step 2 Clinical Knowledge (CK) scores, and specialty choice were conducted, as approved by our Institutional Review Board. Volunteers, compared to nonvolunteers, had higher GPA (3.59 ± 0.33 vs. 3.40 ± 0.39, p < .001), Step 1 (229 ± 19 vs. 220 ± 21, p < .001), and Step 2 CK (240 ± 18 vs. 230 ± 21, p < .001) scores, but did not pursue primary care specialties at a significantly higher percentage (52% vs. 51%, χ² = .051, p = .82). Further exploration of the associations between service and academic achievement and primary care specialty choice is warranted.

MMPI-2 test is widely used in psychodiagnostic evaluation as well as in the evaluation of psychic pathologies related to psychosocial adversative events in working activities. A more efficacious use of MMPI-2 test in the working context can be achieved by the individuation of indexes able to facilitate the evaluation of mobbing syndrome. This work is based on the analysis of 150 cases (39.7% women and 60.7% men, 30 to 60 years of age), evaluated through an accurate examination of working history and a series of clinic conversations, followed by psychodiagnostic evaluation. The average of T-scores on the clinical scale, the content scale, the PK addition scale and the validation scale were calculated from tests. Pathologic high T-scores on the scales Hs, D. Hy e Pa were found in subjects having positive mobbing anamnesis. These results strongly indicate the presence of clinical specificities in workers exposed to working harassments, and that these specificities can be efficaciously evidenced by the MMPI-2 test.

Clinical management of aggression depends on the availability of easily administrable measurements allowing reliable evaluation. The present study's aim is to validate a Clinical Global Impression-Severity of Aggression scale (CGI-A). 558 inpatients with psychiatric disorders and an agitated-aggressive syndrome at baseline were continuously assessed over 5 days using CGI-A and the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC). Equipercentile linking, correlation analyses and linear regression were applied. Relationship between CGI-A and PANSS-EC total score was found to be linear. On a 5-level CGI-A scale, values of 1 to 5 points were found to correspond to PANSS-EC scores of 12.2, 16.7, 21.3, 25.8, and 30.4, respectively (average increase: 4.6). All findings remained stable when only data from patients with schizophrenia spectrum disorders were analyzed. The CGI-A is proposed as a quickly administrable scale for the assessment of patients' aggressiveness.

The authors present what is to their knowledge the first description of a model for longitudinal third-year medical student psychiatry education. A longitudinal, integrated psychiatric curriculum was developed, implemented, and sustained within the Harvard Medical School-Cambridge Integrated Clerkship. Curriculum elements include longitudinal mentoring by attending physicians in an outpatient psychiatry clinic, exposure to the major psychotherapies, psychopharmacology training, acute psychiatry "immersion" experiences, and a variety of clinical and didactic teaching sessions. The longitudinal psychiatry curriculum has been sustained for 8 years to-date, providing effective learning as demonstrated by OSCE scores, NBME shelf exam scores, written work, and observed clinical work. The percentage of students in this clerkship choosing psychiatry as a residency specialty is significantly greater than those in traditional clerkships at Harvard Medical School and greater than the U.S. average. Longitudinal integrated clerkship experiences are effective and sustainable; they offer particular strengths and opportunities for psychiatry education, and may influence student choice of specialty.

Impact of Dry Eye Syndrome on Vision-Related Quality of Life in a Non-Clinic-Based General Population

PubMed Central

2012-01-01

Background Dry eye syndrome (DES) is a common ocular disorder occurring in general population. The purpose of this study is to evaluate the impact of DES on vision-related quality of life (QoL) in a non-clinic-based general population. Methods This population-based cross-sectional study enrolled subjects older than 40 years, who took part in an epidemiological study on dry eye in Sanle Community, Shanghai. Apart from the collection of sociodemographics, dry eye symptoms, and other clinical data, a Chinese version of the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) was administered to all subjects. Comparisons of the NEI VFQ-25 subscale item scores and composite score were made among subgroups divided according to the presence of dry eye symptoms or signs. Multivariate regression analysis was performed to investigate the relationship between the clinical variables and the VFQ-25 composite score. Results A total of 229 participants were enrolled in the study, with an average age of (60.7 ±10.1) years old. Majority of these participants were female (59.8 %, 137/229). The total DES symptom scores (TDSS) in subjects either with definite DES or only with dry eye symptoms were significantly higher (F = 60.331, P < 0.001). The values of tear break-up time (TBUT) and Schirmer test were significantly lower in participants with DES and those with dry eye signs only (F = 55.158 and 40.778, P < 0.001). The composite score of the NEI VFQ-25 was significantly lower in subjects with DES (F = 4.901, P = 0.003). Moreover, the subscale scores of ocular pain and mental health were significantly lower in those with either DES or dry eye symptoms only (F = 10.962 and 7.362 respectively, both P < 0.001). The multiple regression analysis showed that the TDSS had a significant negative correlation with the VFQ-25 composite score as well as with the subscale score for ocular pain and mental health, even after the adjustment of all other factors (all P < 0.01). Conclusions The symptoms of dry eye are associated with an adverse impact on vision-related QoL in non-clinic-based general population, which is mainly represented as more ocular pain and discomfort, and impaired mental health as well. Apart from clinical examination, it is also important to refer to subjective symptoms and QoL scores when assessing the severity of DES. PMID:22799274

The aim of this study is to report the clinical and functional outcomes following arthroscopic management of anterior impingement, grade III-IV cartilage lesions, and mild to moderate osteoarthritis of the ankle in former soccer players. The study included 15 former male professional soccer players with mild to moderate degenerative changes of the ankle who had undergone arthroscopic debridement and management of secondary injuries of the ankle. Preoperatively and at the last follow-up, at an average of 7.4 years, the American Orthopaedic Foot and Ankle Society (AOFAS) and the Kaikkonen scales and visual analogue scale (VAS) assessment were administered to all patients. Ankle osteoarthritis was assessed from weightbearing anteroposterior and lateral radiographs of both ankles. At the last follow-up, the average AOFAS score had increased significantly from 48 (range, 29-69) to 86 (range, 63-94) (P < 0.0001), with good to excellent scores in 11 patients (74 %). The average Kaikkonen preoperative score of 43 (range, 28-70) had significantly improved to 85 (range, 61-95) (P < 0.0001), with good excellent scores in 11 patients (74 %). VAS values were also improved at the last follow-up. At the last appointment, only one (7 %) patient had abandoned altogether any sport, as he did not feel safe with his ankle and he felt too old to continue. Anterior ankle arthroscopy for management of mild to moderate ankle arthritis is safe, effective, and low cost and allows former athletes to safely return to ordinary daily activities and recreational sport activities.

Summary Introduction: Research on the workplace has emphasized the effects of noise exposure on workers' hearing, but has not considered the effects of agrochemicals. Aim: To evaluate and correlate the hearing level and tinnitus of workers exposed simultaneously to noise and organophosphates in their workplace and to measure tinnitus distress on their quality of life. Method: A retrospective clinical study. We evaluated 82 organophosphate sprinklers from the São Paulo State Regional Superintendence who were active in the fight against dengue and who were exposed to noise and organophosphates. We performed pure tone audiometry and applied the translated THI (Tinnitus Handicap Inventory) questionnaire. Results: Of the sample, 28.05% reported current tinnitus or had presented tinnitus, and the workers with tinnitus had an increased incidence of abnormal audiometry. The average hearing threshold for the 4–8-kHz frequency range of the workers with current tinnitus was higher than that of the others, and was most affected at the 4-kHz frequency. The THI score ranged 0–84, with an average score of 13.1. Twelve (52.17%) workers had THI scores consistent with discrete handicap. Conclusion: There is an increased incidence of abnormal pure tone audiometry in workers with tinnitus, and its impact on the workers' quality of life was discrete. The correlation between average hearing threshold and tinnitus distress was weak. PMID:25991953

Traditional Dental Aptitude Test and academic grade point average have been shown to be poor predictors of clinical performance by dental students. To refine predictors of psychomotor skills, a wire-bending test was given to 105 freshmen at the beginning of their dental education. Grades from seven restorative preclinical courses in their freshman and sophomore years were compared to scores on wire bending and the three traditional predictors: GPA, academic aptitude, and perceptual aptitude scores. Wire-bending scores correlated significantly with six out of seven preclinical restorative courses. The predictive power for preclinical performance was doubled when wire bending was added to traditional predictors in stepwise multiple regression analysis. Wire-bending scores identified students of low performance. These preliminary results suggest that the wire-bending test shows some potential as a screening test for identifying students who may hae psychomotor difficulties, early in their dental education.

This study investigated the validity of four approaches (the average, most recent, highest-within-administration, and highest-across-administration approaches) of using repeaters' Medical College Admission Test (MCAT) scores to predict Step 1 scores. Using the differential predication method, this study investigated the magnitude of differences in the expected Step 1 total scores between MCAT nonrepeaters and three repeater groups (two-time, three-time, and four-time test takers) for the four scoring approaches. For the average score approach, matriculants with the same MCAT average are expected to achieve similar Step 1 total scores regardless of whether the individual attempted the MCAT exam one or multiple times. For the other three approaches, repeaters are expected to achieve lower Step 1 scores than nonrepeaters; for a given MCAT score, as the number of attempts increases, the expected Step 1 decreases. The effect was strongest for the highest-across-administration approach, followed by the highest-within-administration approach, and then the most recent approach. Using the average score is the best approach for considering repeaters' MCAT scores in medical school admission decisions.

Background: Proximal interphalangeal (PIP) fracture dislocations remain a complex injury pattern to treat. There are several treatment methods available aimed to restore stability, preserve range of motion, and reconstitute the articular surface. This study looked at the mid-term clinical and radiographic results of open reduction internal fixation through a shotgun approach of comminuted PIP fracture dislocations. Methods: A retrospective review was conducted of all PIP fracture dislocations treated through a volar, shotgun approach at a single institution over a 15-year period. Patients identified were contacted and asked to return to the office for clinical and radiographic evaluation. Patient reported outcomes were assessed with the Michigan hand questionnaire (MHQ) and visual analog scale (VAS) for pain. Results: 5 patients returned to the office for further evaluation with average follow-up of 69 months (range, 33-133 months). 3 patients were found to have post traumatic arthritis on radiographs. 1 case had recurrent instability and one case had a deep infection, both necessitating further surgical intervention. Average PIP arc of motion was found to be 79°. Average VAS score of 0 and MHQ result of 95 (out of a possible score of 100) indicating no residual pain and excellent functionality of the affected hand. Conclusion: Open reduction internal fixation of comminuted PIP fracture dislocations utilizing the volar, shotgun approach provides excellent mid-term functional results despite the high incidence of post traumatic arthritis.

Various professional societies, clinical practices, hospitals, and health care-related Web sites provide Internet-based patient education material (IPEMs) to the general public. However, this information may be written above the 6th-grade reading level recommended by the US Department of Health and Human Services. The purpose of this study is to assess the readability of facial fracture (FF)-related IPEMs and compare readability levels of IPEMs provided by four sources: professional societies, clinical practices, hospitals, and miscellaneous sources. Analysis of IPEMs on FFs available on Google.com. The readability of 41 FF-related IPEMs was assessed with four readability indices: Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES), Simple Measure of Gobbledygook (SMOG), and Gunning Frequency of Gobbledygook (Gunning FOG). Averages were evaluated against national recommendations and between each source using analysis of variance and t tests. Only 4.9% of IPEMs were written at or below the 6th-grade reading level, based on FKGL. The mean readability scores were: FRES 54.10, FKGL 9.89, SMOG 12.73, and Gunning FOG 12.98, translating into FF-related IPEMs being written at a "difficult" writing level, which is above the level of reading understanding of the average American adult. IPEMs related to FFs are written above the recommended 6th-grade reading level. Consequently, this information would be difficult to understand by the average US patient.

The tendency to use portfolios for evaluation has been developed with the aim of optimizing the culture of assessment. The present study was carried out to determine the effect of using portfolios as an evaluation method on midwifery students' learning and satisfaction in prenatal practical training. In this prospective cohort study, all midwifery students in semester four (n=40), were randomly allocated to portfolio and routine evaluation groups. Based on their educational goals, the portfolio groups prepared packages which consisted of a complete report of the history, physical examinations, and methods of patient management (as evaluated by a checklist) for women who visited a prenatal clinic. During the last day of their course, a posttest, clinical exam, and student satisfaction form were completed. The two groups' mean age, mean pretest scores, and their prerequisite course that they should have taken in the previous semester were similar. The mean difference in the pre and post test scores for the two groups' knowledge and comprehension levels did not differ significantly (P>0.05). The average scores on questions in Bloom's taxonomy 2 and 3 of the portfolio group were significantly greater than those of the routine evaluation group (P=0.002, P=0.03, respectively). The mean of the two groups' clinical exam scores was significantly different. The portfolio group's mean scores on generating diagnostic and therapeutic solutions and the ability to apply theory in practice were higher than those of the routine group. Overall, students' satisfaction scores in the two evaluation methods were relatively similar. Portfolio evaluation provides the opportunity for more learning by increasing the student's participation in the learning process and helping them to apply theory in practice.

To explore clinical effect of modified Chevron osteotomy combined with lateral tissue loosening for the treatment of mild-moderate hallux valgus through internal signal approach. From July 2015 to June 2016, 26 patients with mild-moderate hallux valgus treated with modified Chevron osteotomy combined with lateral tissue loosening through internal signal approach, including 2 males and 24 females aged from 45 to 65 years old with an average of(54.6±4.8) years old;the courses of diseases ranged from 1 to 5 months with an average of (7.5±3.3) months. Hallux valgus angle(HVA), inter metatarsal angle(IMA) were measured at 12 months after operation, and AOFAS score was applied to evaluate clinical effect before and after operation. All incisions were healed at stage I. No incision occurred infection, metatarsal necrosis and recurrence of hallux valgus deformity. Two patients occurred skin numbness caused by musculocutaneous nerve injury. Twenty-six patients were followed up from 6 to 12 months with an average of(9.12±2.06) months. HVA, IMA were(30.01±3.71)°, (14.00±1.50)° before operation and(9.41±4.16)°, (7.00±0.60)° after operation, which had significant difference. There was statistical significance in AOFAS score before operation 54.77±9.59 and after operation 92.73±5.47, and 19 cases obtained excellent results and 7 moderate. Modified Chevron osteotomy combined with full thread headless pressure screw fixation and lateral tissue loosening for the treatment of mild-moderate hallux valgus has advantages of excellent exposure, simple operation, stable fixation, rapid recovery. Akin osteotomy with internal capsulorrhaphy were used with lateral loosening and could recover soft tissue balance between lateral and internal, and could receive satisfied clinical effects.

ClinicalTrials.gov serves critical functions of disseminating trial information to the public and helping the trials recruit participants. This study assessed the readability of trial descriptions at ClinicalTrials.gov using multiple quantitative measures. The analysis included all 165,988 trials registered at ClinicalTrials.gov as of April 30, 2014. To obtain benchmarks, the authors also analyzed 2 other medical corpora: (1) all 955 Health Topics articles from MedlinePlus and (2) a random sample of 100,000 clinician notes retrieved from an electronic health records system intended for conveying internal communication among medical professionals. The authors characterized each of the corpora using 4 surface metrics, and then applied 5 different scoring algorithms to assess their readability. The authors hypothesized that clinician notes would be most difficult to read, followed by trial descriptions and MedlinePlus Health Topics articles. Trial descriptions have the longest average sentence length (26.1 words) across all corpora; 65% of their words used are not covered by a basic medical English dictionary. In comparison, average sentence length of MedlinePlus Health Topics articles is 61% shorter, vocabulary size is 95% smaller, and dictionary coverage is 46% higher. All 5 scoring algorithms consistently rated CliniclTrials.gov trial descriptions the most difficult corpus to read, even harder than clinician notes. On average, it requires 18 years of education to properly understand these trial descriptions according to the results generated by the readability assessment algorithms. Trial descriptions at CliniclTrials.gov are extremely difficult to read. Significant work is warranted to improve their readability in order to achieve CliniclTrials.gov's goal of facilitating information dissemination and subject recruitment.

The American Academy of Sleep Medicine has published manuals for scoring polysomnograms that recommend time spent in non-rapid eye movement sleep stages (stage N1, N2, and N3 sleep) be reported. Given the well-established large interrater variability in scoring stage N1 and N3 sleep, we determined the range of time in stage N1 and N3 sleep scored by a large number of technologists when compared to reasonably estimated true values. Polysomnograms of 70 females were scored by 10 highly trained sleep technologists, two each from five different academic sleep laboratories. Range and confidence interval (CI = difference between the 5th and 95th percentiles) of the 10 times spent in stage N1 and N3 sleep assigned in each polysomnogram were determined. Average values of times spent in stage N1 and N3 sleep generated by the 10 technologists in each polysomnogram were considered representative of the true values for the individual polysomnogram. Accuracy of different technologists in estimating delta wave duration was determined by comparing their scores to digitally determined durations. The CI range of the ten N1 scores was 4 to 39 percent of total sleep time (% TST) in different polysomnograms (mean CI ± standard deviation = 11.1 ± 7.1 % TST). Corresponding range for N3 was 1 to 28 % TST (14.4 ± 6.1 % TST). For stage N1 and N3 sleep, very low or very high values were reported for virtually all polysomnograms by different technologists. Technologists varied widely in their assignment of stage N3 sleep, scoring that stage when the digitally determined time of delta waves ranged from 3 to 17 seconds. Manual scoring of non-rapid eye movement sleep stages is highly unreliable among highly trained, experienced technologists. Measures of sleep continuity and depth that are reliable and clinically relevant should be a focus of clinical research. © 2018 American Academy of Sleep Medicine

2017-08-01

We performed a systematic review of the published literature to characterize patient demographic, surgical techniques, and functional outcomes to elucidate the complication and revision rates following isolated tibiotalar arthrodesis with anatomically contoured anterior plating. A comprehensive literature search was performed. Inclusion criteria were peer-reviewed studies in English, after 1990, at least 10 patients, and reporting clinical outcomes following contoured anterior plating and with follow-up of at least 80% and 1 year. Primary outcomes were fusion rate, time to fusion, return to activities, satisfaction, and functional outcome scores. Complication rates, reoperation, and revision were also extracted. Eight primary studies with 164 patients met the inclusion criteria. The average sample size was 21 ± 10.0 patients and average age was 49.2 years with 61.6% male. Posttraumatic arthritis (49.4%) was the most common operative indication, followed by primary osteoarthrosis (18.9%). The average follow-up was 21.1 months. At this time, 97.6% of patients went on to uneventful union at a weighted average time of 18.7 weeks postoperatively. AOFAS scores improved significantly ( P < .05). 25% complication rate was reported with wound complication (7.9%) and hardware irritation (6.7%) most common. Overall, 21.3% of patients underwent reoperation; 4 for revision arthrodesis following nonunion. Isolated tibiotalar arthrodesis utilizing anatomically contoured anterior plating demonstrates excellent clinical and functional outcomes at short-term follow-up. Overall, 97.6% of patients went on to fusion and functional outcomes consistently improved following surgery. Furthermore, while one-quarter of patients experienced complications, wound complications were relatively uncommon and less than one-quarter of these required surgical intervention.

The purpose of this study was to determine the time needed to return to personal and professional activities after bilateral simultaneous endoscopic carpal tunnel release. During a retrospective, single-center study, we included a cohort of 30 patients (60 wrists). Patients were evaluated clinically (pain, paresthesia) and functionally (QuickDASH score) pre- and postoperatively. At the last follow-up, patients completed a questionnaire regarding the time needed to resume personal activities using the ADL scale (feeding, personal hygiene and dressing) and return to work. We also evaluated procedure satisfaction and willingness to undergo the surgery again. The average patient age was 60.5 years (range 39-86). At the last follow-up, average time to resume personal activities was 2.2 days (0-14) for feeding, 4.4 days (0-15) for personal hygiene and 3.9 days (0-14) for dressing. Average time to return to recreational activities was 11.7 days (1-60). Average time to return to work was 36.6 days (15-60). Overall, 97% of patients were satisfied or very satisfied with the outcome. All patients would have the bilateral simultaneous surgery again. Bilateral simultaneous endoscopic carpal tunnel release is rarely performed. For mild conditions, contralateral symptom improvement is common after unilateral surgery. Bilateral simultaneous endoscopic carpal tunnel release appears to be disabling right after surgery, but clinical and functional scores are similar after the third postoperative day. These data can be used for patient education and decision making when considering surgery bilateral carpal tunnel syndrome. Bilateral simultaneous endoscopic carpal tunnel release is a feasible and safe procedure. Level IV, case series. Copyright © 2018 SFCM. Published by Elsevier Masson SAS. All rights reserved.

2018-04-06

Since the 1980s, numerous operations have replaced posterior lumbar interbody fusion (PLIF) with human bone. These operations often involve expensive implants and complex procedures. Escalating expenditures in lumbar fusion surgery warrant re-evaluation of classical PLIF with allogeneic ilium and without instrumentation. The purpose of this study was to determine the long-term fusion rate and clinical outcomes of PLIF with allogeneic bone (allo-PLIF). Between 1981 and 2006, 321 patients aged 12-80 years underwent 339 1-level or 2-level allo-PLIFs for degenerative instability and were followed for 1-28 years. Fusion status was determined by radiographs and as available, by computed tomography scans. Clinical outcome was assessed by the Economic/Functional Outcome Scale. Of the 321 patients, 308 were followed postoperatively (average 6.7 years) and 297 (96%) fused. Fusion rates were lower for patients with substance abuse (89%, P = 0.007). Clinical outcomes in 87% of patients were excellent (52%) or good (35%). Economic/Functional Outcome Scale scores after initial allo-PLIF on average increased 5.2 points. Successful fusion correlated with nearly a 2-point gain in outcome score (P = 0.001). A positive association between a patient characteristic and outcome was observed only with age 65 years and greater, whereas negative associations in clinical outcomes were observed with mental illness, substance abuse, heavy stress to the low back, or industrial injuries. The total complication rate was 7%. With 3 decades of follow-up, we found that successful clinical outcomes are highly correlated with solid fusion using only allogeneic iliac bone.

The aim of this study was to compare the clinical and radiographic outcomes between two different plating methods (superior vs. anteroinferior) in minimally invasive plate osteosynthesis (MIPO) for acute displaced clavicular shaft fractures. A prospective, randomized controlled trial was performed in a single centre. Nineteen patients were treated with superior plating and 18 with anteroinferior plating using the MIPO technique. A 3.5-mm locking reconstruction plate was bent preoperatively and applied to either the anteroinferior or superior aspect of the clavicle through two separate incisions. The operating time, time to union, the proportional length difference, complications, and functional outcome of the shoulder joint were evaluated using the Constant score and the University of California Los Angeles (UCLA) score. There was no statistically significant difference in the Constant score and UCLA score. The mean time to union was 16.8 weeks for superior plating and 17.1 weeks for anteroinferior plating (p=0.866). The average operation time was 77.2min in superior plating and 79.4min in anteroinferior plating (p=0.491). One patient in the superior plating group showed plate failure. Despite no significant difference, one patient had nonunion in the superior plating group (p>0.999). From a clinical perspective, although MIPO with anteroinferior plating provides better outcomes especially in complications without statistically significant difference, both plating methods provided satisfactory clinical and radiographic outcomes.

It has been well documented that IQ scores calculated using Canadian norms are generally 2–5 points lower than those calculated using American norms on the Wechsler IQ scales. However, recent findings have demonstrated that the difference may be significantly larger for individuals with certain demographic characteristics, and this has prompted discussion about the appropriateness of using the Canadian normative system with a clinical population in Canada. This study compared the interpretive effects of applying the American and Canadian normative systems in a clinical sample. We used a multivariate analysis of variance (ANOVA) to calculate differences between IQ and Index scores in a clinical sample, and mixed model ANOVAs to assess the pattern of differences across age and ability level. As expected, Full Scale IQ scores calculated using Canadian norms were systematically lower than those calculated using American norms, but differences were significantly larger for individuals classified as having extremely low or borderline intellectual functioning when compared with those who scored in the average range. Implications of clinically different conclusions for up to 52.8% of patients based on these discrepancies highlight a unique dilemma facing Canadian clinicians, and underscore the need for caution when choosing a normative system with which to interpret WAIS-IV results in the context of a neuropsychological test battery in Canada. Based on these findings, we offer guidelines for best practice for Canadian clinicians when interpreting data from neuropsychological test batteries that include different normative systems, and suggestions to assist with future test development.

To investigate the clinical efficacy of combining digital subtraction angiography-guided percutaneous vertebroplasty (PVP) and (125)I seeds implantation for the treatment of spinal osteoplastic metastasis. A combination of PVP and (125)I implantation was conducted for 50 patients with spinal osteoplastic metastasis, while the other 50 patients who received regular radiation therapy were used as a comparison. Visual analogue pain scale (VAS) and score of life quality (EORTCQLQ-30) were determined for all the patients. Surgery was successful in 89 spinal segments of vertebral body in 50 patients. Each segment of vertebral body was injected with 1-5 mL (2.8 mL for thoracic and 3.1 mL for lumbar vertebral body on average) of bone cement. Postoperative X-ray and CT examination showed that all the patients in the PVP group achieved spinal stability. During the follow-up examination from 6 months to 5 years, 49 patients (98.0%) had significantly relieved back pain, and only 1 case (2.0%) had no obvious improvement. Postoperative VAS score and Karnofsky performance score (KPS) were significantly different from the preoperative scores (p<0.05); and compared to the regular treatment group, PVP combined (125)I seeds showed much better clinical efficacy (p<0.05). PVP is a minimally invasive treatment with easy operation and less complications. PVP can effectively relieve the pain, stabilize the spine, improve the life quality, and reduce the occurrence of paraplegia in patients with spinal osteoplastic metastasis. Utilization of (125)I seeds with PVP can enhance the clinical efficacy.

The purpose of this study is to evaluate the association of the pre-internship Objective Structured Clinical Examination (OSCE) in final year medical students with comprehensive written examinations. SUBJECTS AND MATERIAL: All medical students of October 2004 admission who took part in the October 2010 National Comprehensive Pre-internship Examination (NCPE) and pre-internship OSCE were included in the study (n = 130). OSCE and NCPE scores and medical grade point average (GPA) were collected. GPA was highly correlated with NCPE (r = 0.76 and P<0.001) and moderately with OSCE (r = 0.68 and P < 0.001). Similarly a moderate correlation was observed between NCPE and OSCE scores(r = 0.6 and P < 0.001).Linear stepwise regression shows r(2) of a model applying GPA as predictor of OSCE score is 0.46 (β = 0.68 and P < 0.001), while addition of gender to the model increases r(2) to 0.59 (β = 0.61 and 0.36, for GPA and male gender, respectively and P < 0.001). Logistic forward regression models shows male gender and GPA are the only dependent predictors of high score in OSCE. OR of GPA and male gender for high OSCE score are 4.89 (95% CI = 2.37-10.06) and 6.95 (95% CI = 2.00-24.21), respectively (P < 0.001). Our findings indicate OSCE and examination which mainly evaluate knowledge, judged by GPA and NCPE are moderately to highly correlated. Our results illustrate the interwoven nature of knowledge and clinical skills. In other words, certain level of knowledge is crucial for appropriate clinical performance. Our findings suggest neither OSCE nor written forms of assessments can replace each other. They are complimentary and should also be combined by other evaluations to cover all attributes of clinical competence efficiently.

To evaluate the clinical outcome of arthroscopic repair method of meniscus injury with Fast-fix under local anesthesia. From October 2005 to September 2012,106 patients with meniscus injuries admitted into our - hospital were studied, including 74 males and 32 females, ranging in age from 13 to 71 years old, averaged 27.6 years old. The duration of the disease ranged from 15 days to 5 years. The main clinical manifestations included knee joint pain after exercise, joint locking, pressing pain of knee joint and positive McMurray signs. The MRI showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-fix under local anesthesia. Each patient was assessed with VAS pain evaluation and Lysholm knee-joint score system before and after operation. All the patients were followed up more than 1 year. One hundred and 2 patients were followed up by recording subjective symptoms, clinical examinations and questions naires for an average of 2.6 years (ranged, 1.1 to 8 years), and 4 patients lost follow-up. All the 102 patients had no anesthetic complications. Ninety-six patients had normal subjective symptom and clinical examinations. Four patients had a mild ache with activities,2 patients had moderate pain after activities with joint space pressing pain. VAS pain evaluation and Lysholm knee-joint score after operation both were much better than that before operation. onclusion: Local anesthesia can provide nice circumstances for surgeries. Arthroscopic repair using Fast-fix is an idea method for meniscus injury, especially for the posterior horn tear of medial meniscus, which is simple and convenient with less complications, and satisfactory results.

Shivering during induced normothermia (IN) remains a therapeutic limitation. We investigated potential risk factors and clinical implications of shivering during IN. Post hoc analysis was performed on 24 patients enrolled in a clinical trial of an automated surface cooling system to achieve IN. Hyponatremia was defined as serum levels <136 mmol/L and hypomagnesaemia as levels <1.5 mg/dL. Continuous heat energy transfer (kcal/h) was averaged hourly. Glasgow Coma Scale (GCS) scores were recorded every 2 h. Shivering status was documented hourly. Mixed effects modeling was used to determine clinical measures associated with shivering. Generalized estimating equation (GEE) models were used to compare baseline-adjusted repeated-measures GCS scores. About of 24 (39%) patients demonstrated shivering. Shivering was associated with men (67% vs. 21%, P = 0.03), hyponatremia (44% vs. 7%, P = 0.03), and hypomagnesaemia (56% vs. 7%, P = 0.02). The average kcal/h (158 +/- 645 kcal/h vs. 493 +/- 645 kcal/h, P = 0.03) was greater in shivering patients. Shivering was positively associated with increases in heart rate (P < 0.001), respiratory rate (P < 0.001), and kcal/h (P < 0.001). Non-shivering patients showed a greater increase from baseline GCS (GEE, P = 0.02) at 24 h. No differences in sedative doses or fever burden were noted between shiverers and non-shiverers. Men, hyponatremia, and hypomagnesaemia may predispose febrile patients treated with IN to shivering. Shivering dramatically increases the amount of heat transfer required to maintain normothermia, and may be associated with adverse effects on level of consciousness.

Metabolic syndrome (MetS) increases the risk of morbidity and mortality from cardiovascular disease, and exercise training is an important factor in the treatment and prevention of the clinical components of MetS. The aim was to compare the effects of high-intensity interval training and steady-state moderate-intensity training on clinical components of MetS in healthy physically inactive adults. Twenty adults were randomly allocated to receive either moderate-intensity continuous training [MCT group; 60-80% heart rate reserve (HRR)] or high-intensity interval training (HIT group; 4 × 4 min at 85-95% peak HRR interspersed with 4 min of active rest at 65% peak HRR). We used the revised International Diabetes Federation criteria for MetS. A MetS Z-score was calculated for each individual and each component of the MetS. In intent-to-treat analyses, the changes in MetS Z-score were 1.546 (1.575) in the MCT group and -1.249 (1.629) in the HIT group (between-groups difference, P =  0.001). The average number of cardiometabolic risk factors changed in the MCT group (-0.133, P = 0.040) but not in the HIT group (0.018, P = 0.294), with no difference between groups (P = 0.277). Among apparently healthy physically inactive adults, HIT and MCT offer similar cardiometabolic protection against single MetS risk factors but differ in their effect on average risk factors per subject.

Lumbar spondylolisthesis is a common cause of morbidity in middle aged individuals. Spinal fusion with instrumentation has become the gold standard for lumbar segmental instability. Studies which correlate the improvement in radiology postoperatively with functional outcome show contrasting reports. This study is aimed at finding the correlation between clinical and radiological outcomes after surgery with transforaminal lumbar interbody fusion. A retrospective study in 35 patients who underwent transforaminal lumbar interbody fusion in a period of 1 year was done. Preoperative pain (VAS Score), functional ability (ODI), radiological parameters (slip angle, slip grade, disc height, foraminal height, lumbar lordosis) were compared with postoperative recordings at the last followup. Functional improvement (Macnab's criteria) and fusion (Lee's fusion criteria) were assessed. Statistical analysis was done with student's paired t -test and Pearson's correlation coefficient. VAS score, ODI improved from 8 to 2 and 70 to 15 respectively. Slip angle improved from 23°to 5° on an average. 80% patients showed fusion and 85% showed good clinical outcome at 1 year followup. Analyzing with Pearson correlation coefficient showed no significant relation between pain scores and radiological parameters. But there was statistically significant relation between radiological fusion and the final clinical outcome. TLIF produces spinal fusion in most individuals. Strong spinal fusion is essential for good clinical outcome in spondylolisthesis patients who undergo TLIF. Reduction in slip is not necessary for all patients with listhesis.

Misclassification of OSA severity with automated scoring of home sleep recordings.

The advent of home sleep testing has allowed for the development of an ambulatory care model for OSA that most health-care providers can easily deploy. Although automated algorithms that accompany home sleep monitors can identify and classify disordered breathing events, it is unclear whether manual scoring followed by expert review of home sleep recordings is of any value. Thus, this study examined the agreement between automated and manual scoring of home sleep recordings. Two type 3 monitors (ApneaLink Plus [ResMed] and Embletta [Embla Systems]) were examined in distinct study samples. Data from manual and automated scoring were available for 200 subjects. Two thresholds for oxygen desaturation (≥ 3% and ≥ 4%) were used to define disordered breathing events. Agreement between manual and automated scoring was examined using Pearson correlation coefficients and Bland-Altman analyses. Automated scoring consistently underscored disordered breathing events compared with manual scoring for both sleep monitors irrespective of whether a ≥ 3% or ≥ 4% oxygen desaturation threshold was used to define the apnea-hypopnea index (AHI). For the ApneaLink Plus monitor, Bland-Altman analyses revealed an average AHI difference between manual and automated scoring of 6.1 (95% CI, 4.9-7.3) and 4.6 (95% CI, 3.5-5.6) events/h for the ≥ 3% and ≥ 4% oxygen desaturation thresholds, respectively. Similarly for the Embletta monitor, the average difference between manual and automated scoring was 5.3 (95% CI, 3.2-7.3) and 8.4 (95% CI, 7.2-9.6) events/h, respectively. Although agreement between automated and manual scoring of home sleep recordings varies based on the device used, modest agreement was observed between the two approaches. However, manual review of home sleep test recordings can decrease the misclassification of OSA severity, particularly for those with mild disease.

Castle, Nicholas G; Engberg, John; Liu, Darren

Currently, the Centers for Medicare and Medicaid Services report on 15 Quality Measures (QMs) on the Nursing Home Compare (NHC) website. It is assumed that nursing homes are able to make improvements on these QMs, and in doing so they will attract more residents. In this investigation, we examine changes in QM scores, and whether competition and/or excess demand have influenced these change scores over a period of 1 year. Data come from NHC and the On-line Survey Certification And Recording (OSCAR) system. QM change scores are calculated using values from January 2003 to January 2004. A series of regression analyses are used to examine the association of competition and excess demand on QM scores. Eight QMs show an average decrease in scores (ie, better quality) and six QMs show an average increase in scores (ie, worse quality). However, for 13 of the 14 QMs these average changes averaged less than 1%. The regression analyses show an association between higher competition and improving QM scores and an association between lower occupancy and improving QM scores. As would be predicted based on the market-driven mechanism underlying quality improvements using report cards, we show that it is in the most competitive markets and those with the lowest average occupancy rates that improvements in the QM scores are more likely.

Introduction: The aim of this study was to assess the effect of two-stage warm compress technique on the pain duration of the first and second labor stages and neonatal outcomes. Methods: The clinical trial was done on 150 women (75 subjects in each groups) in Shiraz-affiliated hospitals in 2012 A two-staged warm compress was done for 15-20 minutes in the first and second labor phase (cervical dilatation of 7 and 10 cm with zero status) while the control group received hospital routine care. The duration of labor and Apgar score were evaluated. Results: According to t-test, the average of labor duration was lower in the intervention group compared to the control group at the second stage. However, there was no significant difference for labor duration at the first stage and the first and fifth minute Apgar score. Conclusion: According to the result, this intervention seems a good method for decreasing labor duration at the second stage of parturition. PMID:29637053

Turf toe is a term used to describe a hyperextension injury to the first metatarsophalangeal joint. Although the vast majority of turf toe injuries can be treated successfully without operative intervention, there are instances where surgery is required to allow the athlete to return to play. Although there is a plethora of literature on turf toe injuries and nonoperative management, there are currently few reports on operative outcomes in athletes. We obtained all cases of turf toe repair according to the ICD-10 procedural code. The inclusion criteria included: age greater than 16, turf toe injury requiring operative management and at least a varsity level high school football player. The charts were reviewed for age, BMI, level of competition, injury mechanism, football position, setting of injury and playing surface. In addition, we recorded the specifics of the operative procedure, a listing of all injured structures, the implants used and the great toe range of motion at final follow-up visit. The AOFAS Hallux score and VAS was used postoperatively as our outcome measures. Our patient population included 15 patients. The average follow-up time was 27.5 months. The average patient was 19.3 years old with a body mass index of 32.3. The average playing time missed was 16.5 weeks. The average dorsiflexion range of motion at the final follow-up was 42.3 degrees. At final follow-up, the average AOFAS Hallux score was 91.3. The average VAS pain score was 0.7 at rest and 0.8 with physical activity. Complete turf toe injuries are often debilitating and may require operative management to restore a pain-free, stable, and functional forefoot. This study represents the largest cohort of operatively treated grade 3 turf toe injuries in the literature and demonstrates that good clinical outcomes were achieved with operative repair.

The problem of this study was the lack of knowledge about nutrition, so the use of protein supplements to support the occurrence of muscle hypertrophy is not optimal. The use of natural supplements is a substitute of the manufacturer's supplements. The purpose of this study was to determine the effect of natural protein supplementation to muscle hypertrophy.The method of the research was a quasi experiment. There are 26 subject and were divided two group. Instrument of this research is to use tape measure and skinfold to measure muscle rim and thickness of fat in arm and thigh muscle. Then to calculate the circumference of the arm and thigh muscles used the formula MTC - (3.14 x TSF). MTC is the arm muscle or thigh muscle and TSF is the thickness of the muscles of the arm or thigh muscles. Data analysis technique used was t test at 5% significant level. The result of the research showed that average score of arm muscle hypertrophy at pretest control group was 255.61 + 17.69 mm and posttest average score was 263.48.58 + 17.21 mm and average score of thigh muscle hypertrophy at pretest control group was 458.32 + 8.72 mm and posttest average score was 468.78 + 11.54 mm. Average score of arm muscle hypertrophy at pretest experiment group was 252.67 + 16.05 mm and posttest average score was 274.58 ± 16.89 mm and average score of thigh muscle hypertrophy at pretest experiment group was 459.49 ± 6.99 mm and posttest average score was 478.70 + 9.05 mm. It can be concluded that there was a significant effect of natural protein supplementation on muscle hypertrophy.

To assess whether there is a difference in ENT knowledge amongst nurses caring for patients on a dedicated ENT ward and nurses caring for ENT patients in a similar hospital without a dedicated ENT ward. A test of theoretical knowledge of ENT nursing care was devised and administered to nurses working on a dedicated ENT ward and then to nurses working on generic non-subspecialist wards regularly caring for ENT patients in a hospital without a dedicated ENT ward. The test scores were then compared. A single specialist ENT/Maxillo-Facial/Opthalmology ward in hospital A and 3 generic surgical wards in hospital B. Both hospitals are comparable district general hospitals in the south west of England. Nursing staff working in hospital A and hospital B on the relevant wards were approached during the working day. 11 nurses on ward 1, 10 nurses on ward 2, 11 nurses on ward 3 and 10 nurses on ward 4 (the dedicated ENT ward). Each individual test score was used to generate an average score per ward and these scores compared to see if there was a significant difference. The average score out of 10 on ward 1 was 6.8 (+/-1.6). The average score on ward two was 4.8 (+/-1.6). The average score on ward three was 5.5 (+/-2.1). The average score on ward 4, which is the dedicated ENT ward, was 9.7 (+/-0.5). The differences in average test score between the dedicated ENT ward and all of the other wards are statistically significant. Nurses working on a dedicated ENT ward have an average higher score in a test of knowledge than nurses working on generic surgical wards. This difference is statistically significant and persists despite banding or training. © 2014 John Wiley & Sons Ltd.

2015-11-01

Fatigue is not only a core symptom of major depressive disorder (MDD), but also a common residual symptom. We determined the sociodemographic, clinical, and pharmacologic factors that were associated with fatigue in patients with remission or partial remission of MDD. Data was derived from a randomized controlled trial of acupuncture in 137 MDD patients with residual symptoms. Fatigue was measured by Multidimensional Fatigue Inventory (MFI-20). Self-report and clinician-rated scales were used to assess psychopathology. 17-item Hamilton Depression Rating Scale (HDRS17) score≤7 denoted MDD remission. Participants' average HDRS17 score was 10.5; 29.2% were in remission. The average MFI-20 score was 71.8; 83.2% had severe fatigue, defined as MFI-20 score≥60. Fifty-two of 137 participants (38%) were using sedating psychotropic medications. Antidepressant dosage ranged from 1-90mg fluoxetine equivalent and sedatives/hypnotics from 1-60mg diazepam equivalent. There were significant correlations between MFI-20 score and HDRS17 depression and anxiety subscores, Hospital Anxiety and Depression Scale (HADS) depression and anxiety subscores, and Pain Catastrophizing Scale score, but insomnia and daytime sleepiness, sociodemographics, current medical conditions, and psychotropic medication use were not significant correlates. Upon multiple regression, HADS and HDRS17 depression scores independently predicted MFI-20 score. In remission and partial remission subgroups, HADS depression score was an independent predictor. Participants were recruited from specialty psychiatric units; hence the findings may not be applicable in non-specialized settings. Fatigue was predicted by depression severity in remitted or partially remitted MDD. Psychotropic medication and higher dosage were not associated with greater fatigue. Copyright © 2015 Elsevier B.V.

Multisource feedback analysis of pediatric outpatient teaching

PubMed Central

2013-01-01

Background This study aims to evaluate the outpatient communication skills of medical students via multisource feedback, which may be useful to map future directions in improving physician-patient communication. Methods Family respondents of patients, a nurse, a clinical teacher, and a research assistant evaluated video-recorded medical students’ interactions with outpatients by using multisource feedback questionnaires; students also assessed their own skills. The questionnaire was answered based on the video-recorded interactions between outpatients and the medical students. Results A total of 60 family respondents of the 60 patients completed the questionnaires, 58 (96.7%) of them agreed with the video recording. Two reasons for reluctance were “personal privacy” issues and “simply disagree” with the video recording. The average satisfaction score of the 58 students was 85.1 points, indicating students’ performance was in the category between satisfied and very satisfied. The family respondents were most satisfied with the “teacher”s attitude,“ followed by ”teaching quality”. In contrast, the family respondents were least satisfied with “being open to questions”. Among the 6 assessment domains of communication skills, the students scored highest on “explaining” and lowest on “giving recommendations”. In the detailed assessment by family respondents, the students scored lowest on “asking about life/school burden”. In the multisource analysis, the nurses’ mean score was much higher and the students’ mean self-assessment score was lower than the average scores on all domains. Conclusion The willingness and satisfaction of family respondents were high in this study. Students scored the lowest on giving recommendations to patients. Multisource feedback with video recording is useful in providing more accurate evaluation of students’ communication competence and in identifying the areas of communication that require enhancement.

Recurrence of glenohumeral dislocation after arthroscopic Bankart repair can be associated with a large osseous defect in the posterosuperior part of the humeral head. Our hypothesis is that remplissage is more effective to prevent recurrence of glenohumeral instability without a severe motion deficit. Engaging Hill-Sachs lesions were observed in 48 of 737 patients (6.5%). Twenty-four patients underwent arthroscopic Bankart repair combined with remplissage (group I) and the other 24 patients underwent arthroscopic Bankart repair alone (group II). Clinical outcomes were prospectively evaluated by assessing the range of motion. Complications, recurrence rates, and functional results were assessed utilizing the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, and the Korean Shoulder Score for Instability (KSSI) score. Capsulotenodesis healing after remplissage was evaluated with magnetic resonance imaging. The average ASES, Rowe, and KSSI scores were statistically significantly higher in group I than group II. The frequency of recurrence was statistically significantly higher in group II. The average loss in external rotation measured with the arm positioned at the side of the trunk was greater in group II and that in abduction was also higher in group II. Compared to single arthroscopic Bankart repair, the remplissage procedure combined with arthroscopic Bankart repair was more effective to prevent the recurrence of anterior shoulder instability without significant impact on shoulder mobility in patients who had huge Hill-Sachs lesions.

As the number of electronic biomedical textual resources increases, it becomes harder for physicians to find useful answers at the point of care. Information retrieval applications provide access to databases; however, little research has been done on using automatic summarization to help navigate the documents returned by these systems. After presenting a semantic abstraction automatic summarization system for MEDLINE citations, we concentrate on evaluating its ability to identify useful drug interventions for fifty-three diseases. The evaluation methodology uses existing sources of evidence-based medicine as surrogates for a physician-annotated reference standard. Mean average precision (MAP) and a clinical usefulness score developed for this study were computed as performance metrics. The automatic summarization system significantly outperformed the baseline in both metrics. The MAP gain was 0.17 (p < 0.01) and the increase in the overall score of clinical usefulness was 0.39 (p < 0.05). PMID:19022398

Quality resident education in point-of-care ultrasound (POC US) is becoming increasingly important in emergency medicine (EM); however, the best methods to evaluate competency in graduating residents has not been established. We sought to design and implement a rigorous assessment of image acquisition and interpretation in POC US in a cohort of graduating residents at our institution. We evaluated nine senior residents in both image acquisition and image interpretation for five core US skills (focused assessment with sonography for trauma (FAST), aorta, echocardiogram (ECHO), pelvic, central line placement). Image acquisition, using an observed clinical skills exam (OSCE) directed assessment with a standardized patient model. Image interpretation was measured with a multiple-choice exam including normal and pathologic images. Residents performed well on image acquisition for core skills with an average score of 85.7% for core skills and 74% including advanced skills (ovaries, advanced ECHO, advanced aorta). Residents scored well but slightly lower on image interpretation with an average score of 76%. Senior residents performed well on core POC US skills as evaluated with a rigorous assessment tool. This tool may be developed further for other EM programs to use for graduating resident evaluation.

EEG training requires iterative exposure of different patterns with continuous feedback from the instructor. This training is traditionally acquired through a traditional fellowship program, but only 28% of neurologists in training plan to do a fellowship in EEG. The purpose of this study was to determine the value of online EEG training to improve EEG knowledge among general neurologists. The participants were general neurologists invited through bulk e-mail and paid a fee to enroll in the virtual EEG program. A 40-question pretest exam was performed before training. The training included 4 online learning units about basic EEG principles and 40 online clinical EEG tutorials. In addition there were weekly live teleconferences for Q&A sessions. At the end of the program, the participants were asked to complete a posttest exam. Fifteen of 20 participants successfully completed the program and took both the pre- and posttest exams. All the subjects scored significantly higher in the posttest compared to their baseline score. The average score in the pretest evaluation was 61.7% and the posttest average was 87.8% (p = .0002, two-tailed). Virtual EEG training can improve EEG knowledge among community neurologists.

A precision medicine approach for psychiatric disease based on repeated symptom scores.

For psychiatric diseases, rich information exists in the serial measurement of mental health symptom scores. We present a precision medicine framework for using the trajectories of multiple symptoms to make personalized predictions about future symptoms and related psychiatric events. Our approach fits a Bayesian hierarchical model that estimates a population-average trajectory for all symptoms and individual deviations from the average trajectory, then fits a second model that uses individual symptom trajectories to estimate the risk of experiencing an event. The fitted models are used to make clinically relevant predictions for new individuals. We demonstrate this approach on data from a study of antipsychotic therapy for schizophrenia, predicting future scores for positive, negative, and general symptoms, and the risk of treatment failure in 522 schizophrenic patients with observations over 8 weeks. While precision medicine has focused largely on genetic and molecular data, the complementary approach we present illustrates that innovative analytic methods for existing data can extend its reach more broadly. The systematic use of repeated measurements of psychiatric symptoms offers the promise of precision medicine in the field of mental health. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Correlating Subjective and Objective Sleepiness: Revisiting the Association Using Survival Analysis

PubMed Central

Aurora, R. Nisha; Caffo, Brian; Crainiceanu, Ciprian; Punjabi, Naresh M.

2011-01-01

Study Objectives: The Epworth Sleepiness Scale (ESS) and multiple sleep latency test (MSLT) are the most commonly used measures of subjective and objective sleepiness, respectively. The strength of the association between these measures as well as the optimal ESS threshold that indicates objective sleepiness remains a topic of significant interest in the clinical and research arenas. The current investigation sought to: (a) examine the association between the ESS and the average sleep latency from the MSLT using the techniques of survival analysis; (b) determine whether specific patient factors influence the association; (c) examine the utility of each ESS question; and (d) identify the optimal ESS threshold that indicates objective sleepiness. Design: Cross-sectional study. Patients and Settings: Patients (N = 675) referred for polysomnography and MSLT. Measurements and Results: Using techniques of survival analysis, a significant association was noted between the ESS score and the average sleep latency. The adjusted hazard ratios for sleep onset during the MSLT for the ESS quartiles were 1.00 (ESS < 9), 1.32 (ESS: 10–13), 1.85 (ESS: 14-17), and 2.53 (ESS ≥ 18), respectively. The association was independent of several patient factors and was distinct for the 4 naps. Furthermore, most of the ESS questions were individually predictive of the average sleep latency except the tendency to doze off when lying down to rest in the afternoon, which was only predictive in patients with less than a college education. Finally, an ESS score ≥ 13 optimally predicted an average sleep latency < 8 minutes. Conclusions: In contrast to previous reports, the association between the ESS and the average sleep latency is clearly apparent when the data are analyzed by survival analysis, and most of the ESS questions are predictive of objective sleepiness. An ESS score ≥ 13 most effectively predicts objective sleepiness, which is higher than what has typically been used in clinical practice. Given the ease of administering the ESS, it represents a relatively simple and cost-effective method for identifying individuals at risk for daytime sleepiness.

An automated multi-modal object analysis approach to coronary calcium scoring of adaptive heart isolated MSCT images

Wu, Jing; Ferns, Gordon; Giles, John; Lewis, Emma

2012-02-01

Inter- and intra- observer variability is a problem often faced when an expert or observer is tasked with assessing the severity of a disease. This issue is keenly felt in coronary calcium scoring of patients suffering from atherosclerosis where in clinical practice, the observer must identify firstly the presence, followed by the location of candidate calcified plaques found within the coronary arteries that may prevent oxygenated blood flow to the heart muscle. This can be challenging for a human observer as it is difficult to differentiate calcified plaques that are located in the coronary arteries from those found in surrounding anatomy such as the mitral valve or pericardium. The inclusion or exclusion of false positive or true positive calcified plaques respectively will alter the patient calcium score incorrectly, thus leading to the possibility of incorrect treatment prescription. In addition to the benefits to scoring accuracy, the use of fast, low dose multi-slice CT imaging to perform the cardiac scan is capable of acquiring the entire heart within a single breath hold. Thus exposing the patient to lower radiation dose, which for a progressive disease such as atherosclerosis where multiple scans may be required, is beneficial to their health. Presented here is a fully automated method for calcium scoring using both the traditional Agatston method, as well as the Volume scoring method. Elimination of the unwanted regions of the cardiac image slices such as lungs, ribs, and vertebrae is carried out using adaptive heart isolation. Such regions cannot contain calcified plaques but can be of a similar intensity and their removal will aid detection. Removal of both the ascending and descending aortas, as they contain clinical insignificant plaques, is necessary before the final calcium scores are calculated and examined against ground truth scores of three averaged expert observer results. The results presented here are intended to show the requirement and feasibility for an automated scoring method that reduces the subjectivity and reproducibility error inherent with manual clinical calcium scoring.

Abstract This study aimed to compare the efficacy of muscle gap approach under a minimally invasive channel surgical technique with the traditional median approach. In the Orthopedics Department of Traditional Chinese and Western Medicine Hospital, Tongzhou District, Beijing, 68 cases of lumbar spinal canal stenosis underwent surgery using the muscle gap approach under a minimally invasive channel technique and a median approach between September 2013 and February 2016. Both approaches adopted lumbar spinal canal decompression, intervertebral disk removal, cage implantation, and pedicle screw fixation. The operation time, bleeding volume, postoperative drainage volume, and preoperative and postoperative visual analog scale (VAS) score and Japanese Orthopedics Association score (JOA) were compared between the 2 groups. All patients were followed up for more than 1 year. No significant difference between the 2 groups was found with respect to age, gender, surgical segments. No diversity was noted in the operation time, intraoperative bleeding volume, preoperative and 1 month after the operation VAS score, preoperative and 1 month after the operation JOA score, and 6 months after the operation JOA score between 2 groups (P > .05). The amount of postoperative wound drainage (260.90 ± 160 mL vs 447.80 ± 183.60 mL, P < .001) and the VAS score 6 months after the operation (1.71 ± 0.64 vs 2.19 ± 0.87, P = .01) were significantly lower in the muscle gap approach group than in the median approach group (P < .05). In the muscle gap approach under a minimally invasive channel group, the average drainage volume was reduced by 187 mL, and the average VAS score 6 months after the operation was reduced by an average of 0.48. The muscle gap approach under a minimally invasive channel technique is a feasible method to treat long segmental lumbar spinal canal stenosis. It retains the integrity of the posterior spine complex to the greatest extent, so as to reduce the adjacent spinal segmental degeneration and soft tissue trauma. Satisfactory short-term and long-term clinical results were obtained. PMID:28796075

Background The shoulder is the second most frequently injured joint after the knee in rugby players and labral tears appear to be common. There is limited data available in the literature regarding the mechanisms of posterior labral injury in rugby players and the management of these injuries. Objective The aim of this study is to report the clinical presentation, arthroscopic findings, surgical technique for repair, and the functional outcome in elite English rugby players with isolated posterior labral injuries. Study Design Case series (level IV evidence) Materials and Methods Over a 5-year period we surgically treated 142 elite rugby players, of whom 11 (7.8%) had isolated posterior labral injuries. All these 11 patients had significant contact injury. Only three (24%) patients had a true posterior shoulder dislocation. Pre- and postoperative assessment included Constant score, Oxford shoulder score, and Oxford instability score. We also assessed the time taken to return to preinjury level of fitness and the complications of surgery. Results Average follow-up was for 32 months (range 17–54 months). The mean Constant score improved from 66 to 99. The Oxford score indicated improvement, decreasing from 33 to 18; similarly, the Oxford instability score also decreased from 52.2 to 12.3. Return to playing rugby at peak level was at a mean of 4.3 months after arthroscopic repair. Conclusion Successful clinical results and rapid return to play can be achieved by appropriate early arthroscopic repair and supervised accelerated rehabilitation for posterior labral tears in elite rugby players.

Lesson plan have important role for biology teachers in teaching and learning process. The aim of this study was intended to gain an overview of lesson plan of biology teachers’ at Senior High Schools in Subang which were the members of biology teachers association in Subang. The research method was descriptive method. Data was collected from 30 biology teachers. The result of study showed that lesson plan profile in terms of subject’s identity had good category with 83.33 % of average score. Analysis on basic competence in fair category with 74.45 % of average score. The compatibility of method/strategy was in fair category with average score 72.22 %. The compatibility of instrument, media, and learning resources in fair category with 71.11 % of average score. Learning scenario was in good category with 77.00 % of average score. The compatibility of evaluation was in low category with 56.39 % of average score. It can be concluded that biology teachers in Subang were good enough in making lesson plan, however in terms of the compatibility of evaluation needed to be fixed. Furthermore, teachers’ training for biology teachers’ association was recommended to increasing teachers’ skill to be professional teachers.

Clinical disease registries offer a rich collection of valuable patient information but also pose challenges that require special care and attention in statistical analyses. The goal of this paper is to propose a statistical framework that allows for estimating the effect of surgical insertion of a percutaneous endogastrostomy (PEG) tube for patients living with amyotrophic lateral sclerosis (ALS) using data from a clinical registry. Although all ALS patients are informed about PEG, only some patients agree to the procedure which, leads to the potential for selection bias. Assessing the effect of PEG is further complicated by the aggressively fatal disease, such that time to death competes directly with both the opportunity to receive PEG and clinical outcome measurements. Our proposed methodology handles the “censoring by death” phenomenon through principal stratification and selection bias for PEG treatment through generalized propensity scores. We develop a fully Bayesian modeling approach to estimate the survivor average causal effect (SACE) of PEG on BMI, a surrogate outcome measure of nutrition and quality of life. The use of propensity score methods within the principal stratification framework demonstrates a significant and positive effect of PEG treatment, particularly when time of treatment is included in the treatment definition.

Purpose To evaluate feasibility and impact of evidence-based medicine (EBM) educational prescriptions (EPs) in medical student clerkships. Methods Students answered clinical questions during clerkships using EPs, which guide learners through the “four As” of EBM. Epidemiology fellows graded EPs using a rubric. Feasibility was assessed using descriptive statistics and student and fellow end-of-study questionnaires, which also measured impact. In addition, for each EP, students reported patient impact. Impact on EBM skills was assessed by change in EP scores over time and scores on an EBM objective structured clinical exam (OSCE) that were compared to controls from the prior year. Results 117 students completed 402 EPs evaluated by 24 fellows. Average score was 7.34/9.00 (SD 1.58). 69 students (59%) and 21 fellows (88%) completed questionnaires. Most students thought EPs improved “Acquiring” and “Appraising.” Almost half thought EPs improved “Asking” and “Applying.” Fellows did not value grading EPs. For 18%of EPs, students reported a “change” or “potential change” in treatment. 56% “confirmed” treatment. EP scores increased by 1.27 (95% CI: 0.81–1.72). There were no differences in OSCE scores between cohorts. Conclusions Integrating EPs into clerkships is feasible and has impact, yet OSCEs were unchanged, and research fellows had limitations as evaluators. PMID:27075864

Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation. We performed a prospective, randomized, blinded, controlled trial at a tertiary care center. Patients (n=403) were randomly assigned to groups given GoLytely, MiraLAX, MiraLAX with bisacodyl (10 mg), or MiraLAX with lubiprostone (24 μg). MiraLAX was combined with 64 oz of Gatorade. All patients were surveyed regarding preparation satisfaction and tolerability. The Ottawa bowel preparation scale was used to grade colon cleanliness. GoLytely was more effective at bowel cleansing (average Ottawa score, 5.1) than MiraLAX alone (average Ottawa score, 6.9) or in combination with lubiprostone (average Ottawa score, 6.8), or bisacodyl (average Ottawa score, 6.3) (P<.001). MiraLAX was associated with a trend toward longer procedure duration (P=.096). Groups given MiraLAX rated the overall experience as more satisfactory than those given GoLytely (P<.001). There were no differences between polyp detection rates (P=.346) or adverse events (P=.823). Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

To examine a case series of reoperations for deep brain stimulation (DBS) leads in which clinical scenarios revealed suboptimal outcome from a previous operation. Suboptimally placed DBS leads are one potential reason for unsatisfactory results after surgery for Parkinson's disease (PD), essential tremor (ET), or dystonia. In a previous study of patients who experienced suboptimal results, 19 of 41 patients had misplaced leads. Similarly, another report commented that lead placement beyond a 2- to 3-mm window resulted in inadequate clinical benefit, and, in 1 patient, revision improved outcome. The goal of the current study was to perform an unblinded retrospective chart review of DBS patients with unsatisfactory outcomes who presented for reoperation. Patients who had DBS lead replacements after reoperation were assessed with the use of a retrospective review of an institutional review board-approved movement disorders database. Cases of reoperation for suboptimal clinical benefit were included, and cases of replacement of DBS leads caused by infection or hardware malfunction were excluded. Data points studied included age, disease duration, diagnosis, motor outcomes (the Unified Parkinson Disease Rating Scale III in PD, the Tremor Rating Scale in ET, and the Unified Dystonia Rating Scale in dystonia), quality of life (Parkinson's Disease Questionnaire-39 in PD), and the Clinician Global Impression scale. The data from before and after reoperation were examined to determine the estimated impact of repeat surgery. There were 11 patients with PD, 7 with ET, and 4 with dystonia. The average age of the PD group was 52 years, the disease duration was 10 years, and the average vector distance of the location of the active DBS contact was adjusted 5.5 mm. Six patients (54%) with PD had preoperative off medication on DBS Unified Parkinson Disease Rating Scale scores that could be compared with postoperative off medication on DBS scores. The average improvement across this group of patients was 24.4%. The Parkinson's Disease Questionnaire-39 improved in the areas of mobility (28.18), activities of daily living (14.77), emotion (14.72), stigma (17.61), and discomfort (17.42). The average age of the ET group was 66 years, the disease duration was 29 years, and the average adjusted distance was 6.1 mm. Five ET patients (83.3%) in the cohort had a prereplacement on DBS Tremor Rating Scale and a postreplacement on DBS Tremor Rating Scale with the average improvement of 60.4%. The average age of the dystonia group was 39 years, the average disease duration was 7 years, and the average adjusted lead distance was 6.7 mm. Three patients (75%) with dystonia had prereplacement on DBS Unified Dystonia Rating Scale and postreplacement on DBS Unified Dystonia Rating Scale scores. Across these 3 dystonia patients, the improvement was 12.8%. Clinician Global Impression scale scores (1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; 7, very much worse) after replacement revealed the following results in patients with PD: 1, 7 patients; 2, 3 patients; 3, 1 patient); with ET (1, 4 patients; 2, 3 patients); and with dystonia (1, 1 patient; 2, 2 patients; 3, 1 patient). The latency from original lead placement to reoperation (repositioning/revision) overall was 28.9 months (range, 2-104 mo); however, in leads referred from outside institutions (n = 11 patients), this latency was 48 months (range, 12-104 mo) compared with leads implanted by surgeons from the University of Florida (n = 11 patients), which was 9.7 months (range, 2-19 mo). The most common clinical history was failure to achieve a perceived outcome; however, history of an asymmetric benefit was present in 4 (18.2%) of 22 patients, and lead migration was present in 3 (13.6%) of 22 patients. There are many potential causes of suboptimal benefit after DBS. Timely identification of suboptimal lead placements followed by reoperation and repositioning/replacement in a subset of patients may improve outcomes.

To assess dentist-assistant interaction and communication styles and their associated factors in Jordan. Three different areas in Amman where private dental clinics heavily cluster were chosen. The researcher visited all dental clinics in these areas and invited dentists to participate in this study. A structured self-administered questionnaire was designed and included the 22 items on staff communication that were used by Gorter and Freeman to assess communication styles. The culturally adapted items were analysed in such a way to reflect the structure that is used in the original study. There was a significant interaction between dentist's gender and communication styles (F = 3.8, P = 0.022). The only significant difference between men and women was for professional leadership style (P = 0.011) where men were more likely to adopt professional leadership style than women. For men, the average score for friendly leadership style was significantly lower than that for other styles. For women, the average score was the highest for gender interacting style which was significantly higher than that for friendly leadership style and professional interacting style, but not business leadership style. Communication and interaction styles between Jordanian dentists and their assistants differ according to gender. Jordanian dentists are less likely to adopt friendly leadership communication style compared with other styles.

To explore the efficacy of partial resection of puborectalis combined with mutilation of internal anal sphincter(IAS) in the treatment of puborectalis syndrome with high anal pressure. Twenty-five cases of puborectalis syndrome with high anal resting pressure in the preoperative examination received the operation of partial resection of puborectalis combined with mutilation of IAS in Zhongnan Hospital of Wuhan University between January 2013 and May 2015. The position of puborectalis was confirmed by touching with the exposure under the transfixion device, and a transverse incision was made by electrotome between 3 and 5 o'clock direction of puborectalis, then partial puborectalis was lifted by vessel clamp at 5 o'clock direction, and about 0.5 cm of muscular tissue was resected. Between 8 to 10 o'clock direction of anal tube, about 1 cm length of transverse incision was made by electrotome, then partial IAS was lifted by vessel clamp and cut off. Preoperative and postoperative 3-month anorectal manometry and defecography were carried out. Wexner constipation score and Cleveland Clinic incontinence score were implemented before surgery and 3, 6, 12 months after operation. This study was registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-ORB-16007695). Of the 25 cases, 18 were male and 7 were female, the average age was 55 years old and the average course of disease was 9 years. Compared with pre-operation, the postoperative 3-month anal resting pressure and maximal squeeze pressure were significantly decreased [(53.56±9.05) mmHg vs. (92.44±7.06) mmHg, (142.80±20.35) mmHg vs. (210.88±20.56) mmHg, respectively, both P=0.000]; anorectal angulation at resting state and forced defecation state increased significantly [(102.32±4.96)degree vs. (95.88±4.01)degree, (117.88±5.95)degree vs. (89.52±3.25)degree, respectively, both P=0.000]. Wexner constipation score of postoperative 3-month, 6-month, 12-month (8.28±3.91, 7.40±3.64 and 8.04±4.74) was significantly lower than the preoperative score (16.00±3.69, all P<0.05), while the score was not significantly different among 3 time points after operation (P>0.05). Cleveland Clinic incontinence score was 0 at postoperative 6 and 12 months, and revealed 20 cases were effective among all the surgical patients(80%). Partial resection of puborectalis combined with mutilation of internal anal sphincter can effectively reduce anal pressure and improve symptoms of outlet obstruction, which is an effective method in the treatment of puborectalis syndrome with high anal pressure.

To evaluate levels of spirituality and hope in patients with diabetic foot ulcers (DFUs) according to sociodemographic factors. This was a primary, prospective, descriptive, analytical, and clinical study. Questionnaires assessing sociodemographic and clinical characteristics of the patients, the Spirituality Self-rating Scale (SSRS), and the Herth Hope Index (HHI) were administered to all participants. University-affiliated skilled nursing center and outpatient wound care clinic in Pouso Alegre, Brazil. Fifty adult patients with DFUs participated in the study. Patients with ischemic diabetic foot and mixed ulcers were excluded from the study. On average, patients with DFUs had low levels of spirituality (mean SSRS score, 12.6) and low hope for cure (mean HHI, 16.5). Patients younger than 60 years reported significantly lower levels of spirituality (mean SSRS scores, 11.0), and those older than 70 years had significantly lower hope for cure (mean HHI, 12.5) than other age groups (P = .040). Level of spirituality was significantly lower among women (P = .015) and those living with an ulcer for more than 2 years, who also reported significantly lower hope for cure (P = .029) compared with patients having an ulcer for less than 2 years. On average, patients with DFUs, especially women and older adults, had a low sense of hope and spirituality. Except for gender, age, and ulcer duration, other sociodemographic and ulcer characteristics had no significant effect on the study population's spirituality and hope.

It is not clear whether the pronator quadratus (PQ) muscle actually heals and provides a meaningful pronation force after volar plating for distal radius fractures (DRFs). We aimed to determine whether the length of the PQ muscle, which is dissected and then repaired during volar plating for a DRF, affects the forearm rotation strength and clinical outcomes. We examined 41 patients who requested hardware removal after volar plating. We measured the isokinetic forearm rotation strength and clinical outcomes including grip strength, wrist range of motion, and disabilities of the arm, shoulder and hand (DASH) scores at 6 months after fracture fixation. During the hardware removal surgery, which was performed at an average of 9 months (range, 8.3 to 11.5 months) after fracture fixation, we measured the PQ muscle length. The average PQ muscle length was 68% of the normal muscle length, and no significant relationship was found between the PQ muscle length and the outcomes including isokinetic forearm rotation strength, grip strength, wrist range of motion, and DASH scores. This study demonstrates that the length of the healed PQ muscle does not affect isokinetic forearm rotation strength and clinical outcomes after volar plating for DRFs. The results of this study support our current practice of loose repair of the PQ that is performed by most of the surgeons to prevent tendon irritation over the plate, and suggest that tight repair of the PQ is not necessary for achieving improved forearm function.

To explore medical students' use of computer tutorials embedded in a busy clinical setting; to demonstrate that such tutorials can increase knowledge gain over and above that attributable to the clinical rotation itself. Six tutorials were installed on a computer placed in a central area in an emergency department. Each tutorial was made up of between 33 and 85 screens of information that include text, graphics, animations, and questions. They were designed to be brief (10 minutes), focused, interactive, and immediately relevant. The authors evaluated the intervention using quantitative research methods, including usage tracking, surveys of faculty and students, and a randomized pretest-posttest study. Over 46 weeks, 95 medical students used the tutorials 544 times, for an overall average of 1.7 times a day. The median time spent on completed tutorials was 11 minutes (average [SD], 14 [+/-12] minutes). Seventy-four students completed the randomized study. They completed 65% of the assigned tutorials, resulting in improved examination scores compared with the control (effect size, 0.39; 95% confidence interval = 0.15 to 0.62). Students were positively disposed to the tutorials, ranking them as "valuable." Fifty-four percent preferred the tutorials to small group teaching sessions with a preceptor. The faculty was also positive about the tutorials, although they did not appear to integrate the tutorials directly into their teaching. Medical students on rotation in a busy clinical setting can and will use appropriately presented computer tutorials. The tutorials are effective in raising examination scores.

Traumatic tears of the tibialis posterior (TP) tendon following an ankle sprain are rare. The purpose of this study was to report our case series of TP tendon tears following an ankle sprain. Patients with persistent TP tendon pain after an ankle sprain were retrospectively identified over a 4-year period and reviewed. A comparison of magnetic resonance imaging (MRI) interpretations by a radiologist and surgeon was made. Patients failing conservative management underwent operative repair of the TP tendon tear and concomitant pathology. Failure of the index surgery was defined as TP tendinosis, which was treated with excision and flexor digitorum longus tendon transfer. Outcomes were measured with the Foot Function Index (FFI) and American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scores. Thirteen patients were found to have a TP tendon tear following an ankle sprain. The incidence for TP tears with sprains presented to our clinic was 1.04%. MRI identified TP tendon pathology in 4 patients by a radiologist review and in 11 patients by a surgeon review. The most common concomitant pathology was a talar osteochondral defect in 13 of 13 patients and ligament instability in 12 of 13 patients (5/13 lateral, 3/13 medial, 4/13 multidirectional instability). Four of 13 patients failed the index surgery. Of the 9 remaining patients, 4 had clinical follow-up at an average of 4.6 years postoperatively. The average FFI subscale scores were the following: pain, 40.4; disability, 28.9; and activity, 23.6. The average AOFAS hindfoot score was 68.8. Despite being rare, a TP tendon tear should be included in the differential diagnosis for persistent medial-sided pain following an ankle sprain. MRI findings can be subtle. Associated pathology was very common and likely confounded the diagnosis and outcomes. Patients should be counseled on the possibility of poor outcomes and long-term pain. Level IV, case series.

Abstract Treatment of cervical fracture and dislocation by improving the anterior cervical technique. Anterior cervical approach has been extensively used in treating cervical spine fractures and dislocations. However, when this approach is used in the treatment of locked facet joints, an unsatisfactory intraoperative reduction and prying reduction increases the risk of secondary spinal cord injury. Thus, herein, the cervical anterior approach was improved. With distractor and screw elevation therapy during surgery, the restoration rate is increased, and secondary injury to the spinal cord is avoided. To discuss the feasibility of the surgical method of treating traumatic cervical spine fractures and dislocations and the clinical application. This retrospective study included the duration of patients’ hospitalization from January 2005 to June 2015. The potential risks of surgery (including death and other surgical complications) were explained clearly, and written consents were obtained from all patients before surgery. The study was conducted on 86 patients (54 males and 32 females, average age of 40.1 ± 5.6 years) with traumatic cervical spine fractures and dislocations, who underwent one-stage anterior approach treatment. The effective methods were evaluated by postoperative follow-up. The healing of the surgical incision was monitored in 86 patients. The follow-up duration was 18 to 36 (average 26.4 ± 7.1) months. The patients achieved bones grafted fusion and restored spine stability in 3 to 9 (average 6) months after the surgery. Statistically, significant improvement was observed by Frankel score, visual analog scale score, Japanese Orthopedic Association score, and correction rate of the cervical spine dislocation pre- and postoperative (P < .01). The modified anterior cervical approach is simple with a low risk but a good effect in reduction. In addition, it can reduce the risk of iatrogenic secondary spinal cord injury and maintain optimal cervical spine stability as observed during follow-ups. Therefore, it is suitable for clinical promotion and application. PMID:28658125

Non-variceal upper gastrointestinal bleeding (UGIB) is a common problem in everyday clinical practice. While treating patients affected by UGIB, the estimation of the risk of complications is very important. The Rockall Score is one of the methods used in clinical practice that allows doing that. The aim of this paper is to assess the usefulness of the aforementioned scoring system while treating patients with UGIB. The analysis included, 651 patients with nonvariceal UGIB. The average age of the group was 62.86+16.96 years. Each patient was subjected to the retrospective analysis according to the Rockall Scale's criteria. Then the entire group was divided into the complication risk groups according to the obtained amount of points (low<3, moderate 3 to 8, high>8). After dividing into groups the effort has been taken to find a relationship between Rockall Score points and the occurrences of individual complications. Mortality among the respondents amounted to 11.36%. The hospitalization of 97.70% patients with <3 points on the scale progressed without complications (p<0.001; X2=22.90). In the moderate risk group the highest frequency of re-bleeding and need for surgery were observed. Whereas among patients with >8 points the mortality of 78.95% was noted. Rockall Score is a simple and useful method for assessing prognosis for patients with the non-variceal UGIB. The highest scores are obtained by the patients with a great risk of demise. Rockall Score may be used for classifying patients to appropriate risk groups.

Background Recent advances have led to a rapid increase in the number of computed tomography coronary angiography (CTCA) studies performed. While several studies have reported effective dose (E), there is no data available on cancer risk for current CTCA protocols. Methods and Results E and organ doses were estimated, using scanner-derived parameters and Monte Carlo methods, for 50 patients having 16-slice CTCA performed for clinical indications. Lifetime attributable risks (LARs) were estimated with models developed in the National Academies’ Biological Effects of Ionizing Radiation VII report. E of a complete CTCA averaged 9.5 mSv, while that of a complete study, including calcium scoring when indicated, averaged 11.7 mSv. Calcium scoring increased E by 25%, while tube current modulation reduced it by 34% and was more effective at lower heart rates. Organ doses were highest to the lungs and female breast. LAR of cancer incidence from CTCA averaged approximately 1 in 1600, but varied widely between patients, being highest in younger women. For all patients, the greatest risk was from lung cancer. Conclusions CTCA is associated with non-negligible risk of malignancy. Doses can be reduced by careful attention to scanning protocol. PMID:18371595

Syntax is a language skill purported to support children's reading comprehension. However, researchers who have examined whether children with average and below-average reading comprehension score significantly different on spoken-syntax assessments report inconsistent results. To determine if differences in how syntax is measured affect whether children with average and below-average reading comprehension score significantly different on spoken-syntax assessments. Studies that included a group comparison design, children with average and below-average reading comprehension, and a spoken-syntax assessment were selected for review. Fourteen articles from a total of 1281 reviewed met the inclusionary criteria. The 14 articles were coded for the age of the children, score on the reading comprehension assessment, type of spoken-syntax assessment, type of syntax construct measured and score on the spoken-syntax assessment. A random-effects model was used to analyze the difference between the effect sizes of the types of spoken-syntax assessments and the difference between the effect sizes of the syntax construct measured. There was a significant difference between children with average and below-average reading comprehension on spoken-syntax assessments. Those with average and below-average reading comprehension scored significantly different on spoken-syntax assessments when norm-referenced and researcher-created assessments were compared. However, when the type of construct was compared, children with average and below-average reading comprehension scored significantly different on assessments that measured knowledge of spoken syntax, but not on assessments that measured awareness of spoken syntax. The results of this meta-analysis confirmed that the type of spoken-syntax assessment, whether norm-referenced or researcher-created, did not explain why some researchers reported that there were no significant differences between children with average and below-average reading comprehension, but the syntax construct, awareness or knowledge, did. Thus, when selecting how to measure syntax among school-age children, researchers and practitioners should evaluate whether they are measuring children's awareness of spoken syntax or knowledge of spoken syntax. Other differences, such as participant diagnosis and the format of items on the spoken-syntax assessments, also were discussed as possible explanations for why researchers found that children with average and below-average reading comprehension did not score significantly differently on spoken-syntax assessments. © 2017 Royal College of Speech and Language Therapists.

To investigate the surgical technique and the clinical results of total knee arthroplasty (TKA) in treating end-stage gonarthrosis combined with valgus knee deformity. Between November 1998 and October 2010, 64 patients (72 knees) with end-stage gonarthrosis combined with valgus knee deformity underwent TKA by a medial parapatellar approach. Of the 64 patients, 18 were male and 46 were female with an average age of 62.5 years (range, 23-82 years), including 44 cases (49 knees) of osteoarthritis, 17 cases (20 knees) of rheumatoid arthritis, 2 cases (2 knees) of haemophilic arthritis, and 1 case (1 knee) of post-traumatic arthritis. Bilateral knees were involved in 8 cases, and single knee in 56 cases. The flexion and extension range of motion (ROM) of the knee joint was (82.2 +/- 28.7) degrees; the femur-tibia angle (FTA) was (18.0 +/- 5.8) degrees; according to Knee Society Score (KSS) criterion, the preoperative clinical score was 31.2 +/- 10.1 and functional score was 37.3 +/- 9.0. According to Krackow's classification, there were 65 knees of type I and 7 knees of type II. By medial parapatellar approach, conventional osteotomy and Ranawat soft tissue release were performed in all cases. Prosthesis of preserved posterior cruciate ligament were used in 7 cases (7 knees), posterior stabilize prosthesis in 54 cases (60 knees), constrained prosthesis in 4 cases (5 knees). Incisions healed by first intention in all cases. Peroneal nerve palsy occurred in 1 patient with haemophilic arthritis, severe valgus deformity (FTA was 41 degrees), and flexion contracture (20 degrees), which was cured after 1 year of conservative treatment. Revison surgery was performed in 1 case of deep infection at 2 years after surgery. All the patients were followed up 4.9 years on average (range, 1-13 years). At last follow-up, the FTA was (7.0 +/- 2.5) degrees, showing significant difference when compared with preoperative value (t = 15.502, P = 0.000). The KSS clinical score was 83.0 +/- 6.6 and functional score was 85.1 +/- 10.5, the flexion and extension ROM of the knee joint was (106.1 +/- 17.0) degrees, all showing significant differences when compared with preoperative values (P < 0.05). Five patients had 12-15 degrees valgus knee deformity, but the function of the affect knees were good. TKA is an effective way for the patients with end-stage gonarthrosis combined with valgus knee deformity by medial parapatellar approach combined with conventional osteotomy and Ranawat soft tissue release. The correction of deformity and improvement of joint function can be achieved significantly. The clinical result is satisfactory.

The objective of this study is to assess clinical variables that may be associated with risk for opioid misuse in individuals with chronic pancreatitis. This study utilized a descriptive, quasi-experimental, cross sectional design. Three hundred seven individuals with nonalcoholic chronic pancreatitis engaged in chronic opioid therapy for pain presented to an outpatient specialty clinic at an academic medical center. Participants completed the Current Opioid Misuse Measure (COMM), Brief Pain Inventory (BPI), Short Form (SF)-12 Quality of Life Measure, Center for Epidemiological Studies 10-item Depression Scale (CESD), and a single item asking about current alcohol use. Mean scores on the CESD, COMM, BPI, SF-12, and factors associated with opioid misuse measures from regression analyses were the outcome measures. Mean scores on the CESD, COMM, BPI pain-on-average item, and the SF-12 physical and psychological quality of life factors (t scores) were 11.2 (standard deviation [SD] = 6.7), 8.5 (SD = 7.3), 4.8 (SD = 2.8), 39.7 (SD = 7.0), and 45 (SD = 9.0), respectively. Descriptive analyses revealed that 55% of participants scored above the clinical cutoff for depression on the CESD, and 39% scored above the cutoff for opioid misuse concerns on the COMM. Regression analyses identified several factors associated with higher opioid misuse measure scores, including increased depressive symptoms from the CESD (β = 0.38, P < 0.0001), increased pain rating at the time of the office visit (β = 0.16, P = 0.03), impairment of psychological quality of life (β = -0.27, P = 0.001) and endorsement of alcohol use (β = 0.16, P = 0.03). These factors accounted for 37% of the variance in current opioid misuse scores. Depression, quality of life, pain intensity and alcohol use may be good candidate variables for prospective studies to determine clinical risk factors for opioid misuse among patients with pancreatitis.

Mental defeat and cognitive flexibility have been studied as explanatory factors for depression and posttraumatic stress disorder. This study examined mental defeat and cognitive flexibility scores in patients with panic disorder (PD) before and after cognitive behavioral therapy (CBT), and compared them to those of a gender- and age-matched healthy control group. Patients with PD (n = 15) received 16 weekly individual CBT sessions, and the control group (n = 35) received no treatment. Patients completed the Mental Defeat Scale and the Cognitive Flexibility Scale before the intervention, following eight CBT sessions, and following 16 CBT sessions, while the control group did so only prior to receiving CBT (baseline). The patients' pre-CBT Mental Defeat and Cognitive Flexibility Scale scores were significantly higher on the Mental Defeat Scale and lower on the Cognitive Flexibility Scale than those of the control group participants were. In addition, the average Mental Defeat Scale scores of the patients decreased significantly, from 22.2 to 12.4, while their average Cognitive Flexibility Scale scores increased significantly, from 42.8 to 49.5. These results suggest that CBT can reduce mental defeat and increase cognitive flexibility in patients with PD Trial registration The study was registered retrospectively in the national UMIN Clinical Trials Registry on June 10, 2016 (registration ID: UMIN000022693).

Recent studies have examined heterogeneous neuropsychological outcomes in childhood traumatic brain injury (TBI) using cluster analysis. These studies have identified homogeneous subgroups based on tests of IQ, memory, and other cognitive abilities that show some degree of association with specific cognitive, emotional, and behavioral outcomes, and have demonstrated that the clusters derived for children with TBI are different from those observed in normal populations. However, the extent to which these subgroups are stable across abilities has not been examined, and this has significant implications for the generalizability and clinical utility of TBI clusters. The current study addressed this by comparing IQ and memory profiles of 137 children who sustained moderate-to-severe TBI. Cluster analysis of IQ and memory scores indicated that a four-cluster solution was optimal for the IQ scores and a five-cluster solution was optimal for the memory scores. Three clusters on each battery differed primarily by level of performance, while the others had pattern variations. Cross-plotting the clusters across respective IQ and memory test scores indicated that clusters defined by level were generally stable, while clusters defined by pattern differed. Notably, children with slower processing speed exhibited low-average to below-average performance on memory indexes. These results provide some support for the stability of previously identified memory and IQ clusters and provide information about the relationship between IQ and memory in children with TBI.

Individuals with body dysmorphic disorder (BDD) have been postulated to have schizoid, narcissistic, and obsessional personality traits and to be sensitive, introverted, perfectionistic, and insecure. However, data on personality traits and disorders in BDD are limited. This study assessed 148 subjects with BDD, 26 of whom participated in a fluvoxamine treatment study; 74 subjects were assessed for personality disorders with the Structured Clinical Interview for DSMIII-R Personality Disorders (SCID-II), 100 subjects completed the NEO-Five Factor Inventory (NEO-FFI), and 51 subjects completed the Rathus Assertiveness Scale. Forty-two subjects (57%) had one or more personality disorders, with avoidant personality disorder (43%) being most common, followed by dependent (15%), obsessive-compulsive (14%), and paranoid (14%) personality disorders. On the NEO-FFI, the mean scores were in the very high range for neuroticism, the low range for extraversion and conscientiousness, the low-average range for agreeableness, and the average range for openness to experience. On the Rathus Assertiveness Scale, the mean score was -17.1 +/- 32.0 for women and -17.0 +/- 32.3 for men. Among fluvoxamine responders, the number of personality disorders significantly decreased between the study baseline and endpoint. These findings suggest that the rate of personality disorders in BDD is relatively high, with avoidant personality disorder being most common. The high neuroticism scores and low extraversion scores are consistent with this finding.

Anatomo-clinical overlapping maps (AnaCOM): a new method to create anatomo-functional maps from neuropsychological tests and structural MRI scan of subjects with brain lesions

We have developed a new technique to analyze correlations between brain anatomy and its neurological functions. The technique is based on the anatomic MRI of patients with brain lesions who are administered neuropsychological tests. Brain lesions of the MRI scans are first manually segmented. The MRI volumes are then normalized to a reference map, using the segmented area as a mask. After normalization, the brain lesions of the MRI are segmented again in order to redefine the border of the lesions in the context of the normalized brain. Once the MRI is segmented, the patient's score on the neuropsychological test is assigned to each voxel in the lesioned area, while the rest of the voxels of the image are set to 0. Subsequently, the individual patient's MRI images are superimposed, and each voxel is reassigned the average score of the patients who have a lesion at that voxel. A threshold is applied to remove regions having less than three overlaps. This process leads to an anatomo-functional map that links brain areas to functional loss. Other maps can be created to aid in analyzing the functional maps, such as one that indicates the 95% confidence interval of the averaged scores for each area. This anatomo-clinical overlapping map (AnaCOM) method was used to obtain functional maps from patients with lesions in the superior frontal gyrus. By finding particular subregions more responsible for a particular deficit, this method can generate new hypotheses to be tested by conventional group methods.

Background To ensure the rigour of objective structured clinical examinations (OSCEs) in assessing medical students, medical school educators must educate examiners with a view to standardising examiner assessment behaviour. Delivering OSCE examiner training is a necessary yet challenging part of the OSCE process. A novel approach to implementing training for current and potential OSCE examiners was trialled by delivering large-group education sessions at major teaching hospitals. Methods The ‘OSCE Roadshow’ comprised a short training session delivered in the context of teaching hospital ‘Grand Rounds’ to current and potential OSCE examiners. The training was developed to educate clinicians about OSCE processes, clarify the examiners’ role and required behaviours, and to review marking guides and mark allocation in an effort to standardise OSCE processes and encourage consistency in examiner marking behaviour. A short exercise allowed participants to practise marking a mock OSCE to investigate examiner marking behaviour after the training. Results OSCE Roadshows at four metropolitan and one rural teaching hospital were well received and well attended by 171 clinicians across six sessions. Unexpectedly, medical students also attended in large numbers (n=220). After training, participants’ average scores for the mock OSCE clustered closely around the ideal score of 28 (out of 40), and the average scores did not differ according to the levels of clinical experience. Conclusion The OSCE Roadshow demonstrated the potential of brief familiarisation training in reaching large numbers of current and potential OSCE examiners in a time and cost-effective manner to promote standardisation of OSCE processes.

Beyond total treatment effects in randomised controlled trials: Baseline measurement of intermediate outcomes needed to reduce confounding in mediation investigations.

PubMed

Landau, Sabine; Emsley, Richard; Dunn, Graham

2018-06-01

Random allocation avoids confounding bias when estimating the average treatment effect. For continuous outcomes measured at post-treatment as well as prior to randomisation (baseline), analyses based on (A) post-treatment outcome alone, (B) change scores over the treatment phase or (C) conditioning on baseline values (analysis of covariance) provide unbiased estimators of the average treatment effect. The decision to include baseline values of the clinical outcome in the analysis is based on precision arguments, with analysis of covariance known to be most precise. Investigators increasingly carry out explanatory analyses to decompose total treatment effects into components that are mediated by an intermediate continuous outcome and a non-mediated part. Traditional mediation analysis might be performed based on (A) post-treatment values of the intermediate and clinical outcomes alone, (B) respective change scores or (C) conditioning on baseline measures of both intermediate and clinical outcomes. Using causal diagrams and Monte Carlo simulation, we investigated the performance of the three competing mediation approaches. We considered a data generating model that included three possible confounding processes involving baseline variables: The first two processes modelled baseline measures of the clinical variable or the intermediate variable as common causes of post-treatment measures of these two variables. The third process allowed the two baseline variables themselves to be correlated due to past common causes. We compared the analysis models implied by the competing mediation approaches with this data generating model to hypothesise likely biases in estimators, and tested these in a simulation study. We applied the methods to a randomised trial of pragmatic rehabilitation in patients with chronic fatigue syndrome, which examined the role of limiting activities as a mediator. Estimates of causal mediation effects derived by approach (A) will be biased if one of the three processes involving baseline measures of intermediate or clinical outcomes is operating. Necessary assumptions for the change score approach (B) to provide unbiased estimates under either process include the independence of baseline measures and change scores of the intermediate variable. Finally, estimates provided by the analysis of covariance approach (C) were found to be unbiased under all the three processes considered here. When applied to the example, there was evidence of mediation under all methods but the estimate of the indirect effect depended on the approach used with the proportion mediated varying from 57% to 86%. Trialists planning mediation analyses should measure baseline values of putative mediators as well as of continuous clinical outcomes. An analysis of covariance approach is recommended to avoid potential biases due to confounding processes involving baseline measures of intermediate or clinical outcomes, and not simply for increased precision.

Posterior decompression with instrumented fusion (PDF) surgery has been previously reported as a relatively safe surgical procedure for any type of thoracic ossification of the longitudinal ligament (OPLL). However, mid- to long-term outcomes are still unclear. The aim of the present study was to elucidate the mid- to long-term clinical outcome of PDF surgery for thoracic OPLL patients. The present study included 20 patients who had undergone PDF for thoracic OPLL and were followed for at least 5years. Increment change and recovery rate of the Japanese Orthopaedic Association (JOA) score were assessed. Revision surgery during the follow-up period was also recorded. Average JOA scores were 3.5 preoperatively and 7.1 at final follow-up. The average improvement in JOA score was 3.8 points and the average recovery rate was 47.0%. The JOA score showed gradual increase after surgery, and took 9months to reach peak recovery. As for neurological complications, two patients suffered postoperative paralysis, but both recovered without intervention. Six revision surgeries in four patients were related to OPLL. Additional anterior thoracic decompression for remaining ossification at the same level of PDF surgery was performed in one patient. Decompression surgery for deterioration of symptoms of pre-existing cervical OPLL was performed in three patients. One patient had undergone lumbar and cervical PDF surgery for de novo ossification foci of the lumbar and cervical spine. PDF surgery for thoracic OPLL is thus considered a relatively safe and stable surgical procedure considering the mid- to long-term outcomes. Copyright © 2015 Elsevier Ltd. All rights reserved.

Twenty-four healthy mixed-breed dogs were divided into 4 groups. Group 1 received a placebo p.o. q12h, group 2 received an average of 16.5 (15.1-17.8) mg/kg buffered aspirin p.o. q12h, group 3 received an average of 2.2 (2.0-2.4) mg/kg carprofen p.o. q12h, and group 4 received an average of 12.8 (11.7-13.8) mg/kg etodolac p.o. q24h (with a placebo in the PM). All treatments continued for 28 consecutive days. Gastroduodenal endoscopy was performed on days -9, 0, 5, 14, and 28. Multiple gastric biopsies were obtained endoscopically on day -9 to determine each dog's Helicobacter infection status. Four regions in the stomach and 1 region in the proximal duodenum were evaluated endoscopically, and each was assigned a score from 1 to 11. Scores for each region then were summed to give a total score for each endoscopic evaluation. Erosions and submucosal hemorrhages were seen in all dogs receiving aspirin. Only minor gastric lesions were observed in the carprofen, etodolac, and control groups. No adverse clinical signs were noted in any dog given any treatment. Median total score on days 0, 5, 14, and 28, respectively, were as follows: group 1: 5.0, 5.0, 5.0, 5.0; group 2: 5.0, 27.0, 26.0, 27.5; group 3: 5.0, 5.0, 6.0, 5.0, group 4: 5.0, 7.0, 5.0, 5.0. There was no significant difference among dogs receiving carprofen, etodolac, or placebo. The administration of carprofen, etodolac, or placebo to healthy dogs resulted in significantly less gastroduodenal lesion development than in dogs receiving buffered aspirin.

Performance status measures are increasingly completed by patients in outpatient cancer settings, but are not well validated for this use. We assessed performance of a patient-reported functional status measure (PRFS, based on the Eastern Cooperative Oncology Group [ECOG]), compared with the physician-completed ECOG, in terms of agreement in ratings and prediction of survival. Patients and physicians independently completed five-point PRFS (lay version of ECOG) and ECOG measures on first consultation at an oncology palliative care clinic. We assessed agreement between PRFS and ECOG using weighted Kappa statistics, and used linear regression to determine factors associated with the difference between PRFS and ECOG ratings. We used the Kaplan-Meier method to estimate the patients' median survival, categorized by PRFS and ECOG, and assessed predictive accuracy of these measures using the C-statistic. For the 949 patients, there was moderate agreement between PRFS and ECOG (weighted Kappa 0.32; 95% CI: 0.28-0.36). On average, patients' ratings of performance status were worse by 0.31 points (95% CI: 0.25-0.37, P < 0.0001); this tendency was greater for younger patients (P = 0.002) and those with worse symptoms (P < 0.0001). Both PRFS and ECOG scores correlated well with overall survival; the C-statistic was higher for the average of PRFS and ECOG scores (0.619) than when reported individually (0.596 and 0.604, respectively). Patients tend to rate their performance status worse than physicians, particularly if they are younger or have greater symptom burden. Prognostic ability of performance status could be improved by using the average of patients and physician scores. Copyright © 2018 American Academy of Hospice and Palliative Medicine.

Stroke thrombolysis is highly time-critical, but data on long-term effects of small reductions in treatment delays have not been available. Our objective was to quantify patient lifetime benefits gained from faster treatment. Observational prospective data of consecutive stroke patients treated with intravenous thrombolysis in Australian and Finnish centers (1998-2011; n=2258) provided distributions of age, sex, stroke severity, onset-to-treatment times, and 3-month modified Rankin Scale in daily clinical practice. Treatment effects derived from a pooled analysis of thrombolysis trials were used to model the shift in 3-month modified Rankin Scale distributions with reducing treatment delays, from which we derived the expected lifetime and level of long-term disability with faster treatment. Each minute of onset-to-treatment time saved granted on average 1.8 days of extra healthy life (95% prediction interval, 0.9-2.7). Benefit was observed in all groups: each minute provided 0.6 day in old severe (age, 80 years; National Institutes of Health Stroke Scale [NIHSS] score, 20) patients, 0.9 day in old mild (age, 80 years; NIHSS score, 4) patients, 2.7 days in young mild (age, 50 years; NIHSS score, 4) patients, and 3.5 days in young severe (age, 50 years; NIHSS score, 20) patients. Women gained slightly more than men over their longer lifetimes. In the whole cohort, each 15 minute decrease in treatment delay provided an average equivalent of 1 month of additional disability-free life. Realistically achievable small reductions in stroke thrombolysis delays would result in significant and robust average health benefits over patients' lifetimes. The awareness of concrete importance of speed could promote practice change.

Objective To compare the accuracy of data from hospital administration databases and a national clinical cardiac surgery database and to compare the performance of the Dutch hospital standardised mortality ratio (HSMR) method and the logistic European System for Cardiac Operative Risk Evaluation, for the purpose of benchmarking of mortality across hospitals. Methods Information on all patients undergoing cardiac surgery between 1 January 2007 and 31 December 2010 in 10 centres was extracted from The Netherlands Association for Cardio-Thoracic Surgery database and the Hospital Discharge Registry. The number of cardiac surgery interventions was compared between both databases. The European System for Cardiac Operative Risk Evaluation and hospital standardised mortality ratio models were updated in the study population and compared using the C-statistic, calibration plots and the Brier-score. Results The number of cardiac surgery interventions performed could not be assessed using the administrative database as the intervention code was incorrect in 1.4–26.3%, depending on the type of intervention. In 7.3% no intervention code was registered. The updated administrative model was inferior to the updated clinical model with respect to discrimination (c-statistic of 0.77 vs 0.85, p<0.001) and calibration (Brier Score of 2.8% vs 2.6%, p<0.001, maximum score 3.0%). Two average performing hospitals according to the clinical model became outliers when benchmarking was performed using the administrative model. Conclusions In cardiac surgery, administrative data are less suitable than clinical data for the purpose of benchmarking. The use of either administrative or clinical risk-adjustment models can affect the outlier status of hospitals. Risk-adjustment models including procedure-specific clinical risk factors are recommended. PMID:24334377

SU-F-T-352: Development of a Knowledge Based Automatic Lung IMRT Planning Algorithm with Non-Coplanar Beams

Zhu, W; Wu, Q; Yuan, L

Purpose: To improve the robustness of a knowledge based automatic lung IMRT planning method and to further validate the reliability of this algorithm by utilizing for the planning of clinical cases with non-coplanar beams. Methods: A lung IMRT planning method which automatically determines both plan optimization objectives and beam configurations with non-coplanar beams has been reported previously. A beam efficiency index map is constructed to guide beam angle selection in this algorithm. This index takes into account both the dose contributions from individual beams and the combined effect of multiple beams which is represented by a beam separation score. Wemore » studied the effect of this beam separation score on plan quality and determined the optimal weight for this score.14 clinical plans were re-planned with the knowledge-based algorithm. Significant dosimetric metrics for the PTV and OARs in the automatic plans are compared with those in the clinical plans by the two-sample t-test. In addition, a composite dosimetric quality index was defined to obtain the relationship between the plan quality and the beam separation score. Results: On average, we observed more than 15% reduction on conformity index and homogeneity index for PTV and V{sub 40}, V{sub 60} for heart while an 8% and 3% increase on V{sub 5}, V{sub 20} for lungs, respectively. The variation curve of the composite index as a function of angle spread score shows that 0.6 is the best value for the weight of the beam separation score. Conclusion: Optimal value for beam angle spread score in automatic lung IMRT planning is obtained. With this value, model can result in statistically the “best” achievable plans. This method can potentially improve the quality and planning efficiency for IMRT plans with no-coplanar angles.« less

Leadership plays a key role in trauma team management and might affect the efficiency of patient care. Our hypothesis was that a positive relationship exists between the trauma team members' perception of leadership and the efficiency of the injured patient's initial evaluation. We conducted a prospective observational study evaluating trauma attending leadership (TAL) over 5 months at a level 1 trauma center. After the completion of patient care, trauma team members evaluated the TAL's ability using a modified Campbell Leadership Descriptor Survey tool. Scores ranged from 18 (ineffective leader) to 72 (perfect score). Clinical efficiency was measured prospectively by recording the time needed to complete an advanced trauma life support (ATLS)-directed resuscitation. Assessment times across Leadership score groups were compared using Kruskal-Wallis and Mann-Whitney tests (p < 0.05, statistically significant). Seven attending physicians were included with a postfellowship experience ranging from ≤1 to 11 years. The average leadership score was 59.8 (range, 27-72). Leadership scores were divided into 3 groups post facto: low (18-45), medium (46-67), and high (68-72). The teams directed by surgeons with low scores took significantly longer than teams directed by surgeons with high scores to complete the secondary survey (14 ± 4 minutes in contrast to 11 ± 2 minutes, p < 0.009) and to transport the patient for CT evaluation (19 ± 5 minutes in contrast to 14 ± 4 minutes; p < 0.001). Attending surgeon experience also affected clinical efficiency with teams directed by less experienced surgeons taking significantly longer to complete the primary survey (p < 0.05). The trauma team's perception of leadership is associated positively with clinical efficiency. As such, more formal leadership training could potentially improve patient care and should be included in surgical education. Copyright © 2012 Association of Program Directors in Surgery.

Traumatic stress refers to physical and emotional reactions caused by events which represent a life threat or a disturbance of physical and phychological integrity of a child, as well as their parents or gaerdians. Car accidents are the main cause of posttraumatic stress disorder (PTSD) in children. The aim of this study was to preview clinical efficiency of systemic family therapy (SFT) as therapy intervention in treatment of children with posttraumatic stress disorder (PTSD) traumatized in car accident under identical circumstances of exposure. We pointed out the importance of specific family factors (family cohesion and adaptability, emotional reaction of the parents) on PTSD clinical outcome. The sample of this clinical observational study included 7-sixth grade pupiles--5 boys and 2 girls, aged 13. All of the pupils were involved in car accident with one death. Two groups were formed--one group included three children who were involved in 8 SFT sessions together with their families. The second group included 4 children who received an antidepressant sertraline in the period of three months. Two months after the car accident, before the beginning of the therapy, all of the children were the members of rigidly enmeshed family systems, considering the high average cohesion scores and the low average adaptability scores on the FACES III. Three months after the received therapy, having evaluated the results of the therapeutic approaches, we established that the adaptability scores of the families included in the SFT were higher than the scores of the families of the children who received pharmacotherapy with one boy still meeting the criteria for PTSD. Systemic family therapy was efficient in the treatment of children with PTSD, traumatized in car accident. Therapy efficiency was higher when both parents and children were included in SFT than in the case when they were not included in the family therapy. The change in the functioning of the family systems was not accidental or simply time-dependant, but it depended on the therapy which was applied and the increased level of family adaptability as the main risk factor of retraumatization.

Painful spinal metastases usually occur in malignant neoplastic disease. Treatment for bone metastases has been largely conservative, and it includes the use of high doses of analgesics, radiotherapy, chemotherapy, hormone therapy, and bisphosphonates; however, results are sometimes transient and ineffective. In the presence of neurological involvement a surgical strategy should be considered. Recently, percutaneous procedures such as radiofrequency ablation, vertebroplasty, and kyphoplasty have been introduced as palliative techniques to treat painful vertebral metastases [3, 11, 25]. In our study we combined the use of radiofrequency ablation with vertebroplasty in the treatment of dorsolumbar metastatic vertebral fractures in order to examine the relationship between restoration of the vertebral structure and decrease in pain. From January 2014 to March 2015 we retrospectively analyzed 18 patients with malignant vertebral lesions who underwent radiofrequency ablation with vertebroplasty followed by cementoplasty, with posterior transpedicle fixation on levels near the lesions. The parameters examined were: demographics, pain relief, and the distribution of polymethylmethacrylate (PMMA) determined by the mean Saliou filling score; all complications were recorded. The mean age of the patients was 55.72 years (range 34-69); average operative time was 60.4 min (range, 51-72). The average pain index score (visual analog score; VAS) decreased significantly from 8.05 at baseline to 3.0 (p < 0.05) after 6 months. The Saliou filling score revealed a distribution of PMMA in the vertebral body that was satisfactory (12-18) in eight patients, mediocre (6-12) in seven patients, and inadequate (0-6) in the remaining three patients. In two vertebrae, minimal asymptomatic cement leakage occurred in the lateral recess without neurological damage. No pulmonary embolism and no visceral or neural damage was recorded. Radiofrequency ablation combined with vertebroplasty seems to achieve rapid and lasting improvement in clinical symptoms in patients with malignant vertebral lesions. There was wide diffusion of PMMA in the vertebral body, with a mean cement volume of 4.5 ml.

There is a paucity of research on whether application essays are a valid indicator of medical students' future performance. The goal is to score medical school application essays systematically and examine the correlations between these essay scores and several indicators of student performance during medical school and internship. A journalist created a scoring rubric based on the journalism literature and scored 2 required essays of students admitted to our university in 1 year (N = 145). We picked 7 indicators of medical school and internship performance and correlated these measures with overall essay scores: preclinical medical school grade point average (GPA), clinical medical school GPA, cumulative medical school GPA, U.S. Medical Licensing Exam (USMLE) Step 1 and 2 scores, and scores on a program director's evaluation measuring intern professionalism and expertise. We then examined the Pearson and Spearman correlations between essay scores and the outcomes. Essay scores did not vary widely. American Medical College Application Service essay scores ranged from 3.3 to 4.5 (M = 4.11, SD = 0.15), and Uniformed Services University of the Health Sciences essay scores ranged from 2.9 to 4.5 (M = 4.09, SD = 0.17). None of the medical school or internship performance indicators was significantly correlated with the essay scores. These findings raise questions about the utility of matriculation essays, a resource-intensive admission requirement.

Base rates of low ANAM4 TBI-MIL scores were calculated in a convenience sample of 733 healthy male active duty soldiers using available military reference values for the following cutoffs: ≤2nd percentile (2 SDs), ≤5th percentile, <10th percentile, and <16th percentile (1 SD). Rates of low scores were also calculated in 56 active duty male soldiers who sustained an mTBI an average of 23 days (SD = 36.1) prior. 22.0% of the healthy sample and 51.8% of the mTBI sample had two or more scores below 1 SD (i.e., 16th percentile). 18.8% of the healthy sample and 44.6% of the mTBI sample had one or more scores ≤5th percentile. Rates of low scores in the healthy sample were influenced by cutoffs and race/ethnicity. Importantly, some healthy soldiers obtain at least one low score on ANAM4. These base rate analyses can improve the methodology for interpreting ANAM4 performance in clinical practice and research. © The Author 2014. Published by Oxford University Press.

Busch, Robyn M; Lineweaver, Tara T; Ferguson, Lisa; Haut, Jennifer S

2015-06-01

Reliable change indices (RCIs) and standardized regression-based (SRB) change score norms permit evaluation of meaningful changes in test scores following treatment interventions, like epilepsy surgery, while accounting for test-retest reliability, practice effects, score fluctuations due to error, and relevant clinical and demographic factors. Although these methods are frequently used to assess cognitive change after epilepsy surgery in adults, they have not been widely applied to examine cognitive change in children with epilepsy. The goal of the current study was to develop RCIs and SRB change score norms for use in children with epilepsy. Sixty-three children with epilepsy (age range: 6-16; M=10.19, SD=2.58) underwent comprehensive neuropsychological evaluations at two time points an average of 12 months apart. Practice effect-adjusted RCIs and SRB change score norms were calculated for all cognitive measures in the battery. Practice effects were quite variable across the neuropsychological measures, with the greatest differences observed among older children, particularly on the Children's Memory Scale and Wisconsin Card Sorting Test. There was also notable variability in test-retest reliabilities across measures in the battery, with coefficients ranging from 0.14 to 0.92. Reliable change indices and SRB change score norms for use in assessing meaningful cognitive change in children following epilepsy surgery are provided for measures with reliability coefficients above 0.50. This is the first study to provide RCIs and SRB change score norms for a comprehensive neuropsychological battery based on a large sample of children with epilepsy. Tables to aid in evaluating cognitive changes in children who have undergone epilepsy surgery are provided for clinical use. An Excel sheet to perform all relevant calculations is also available to interested clinicians or researchers. Copyright © 2015 Elsevier Inc. All rights reserved.

Executive functioning and episodic memory impairment occur in HIV infection (HIV) and chronic alcoholism (ALC). Comorbidity of these conditions (HIV + ALC) is prevalent and heightens risk of vulnerability to separate and compounded deficits. Age and disease-related variables can also serve as mediators of cognitive impairment and should be considered, given the extended longevity of HIV-infected individuals in this era of improved pharmacological therapy. HIV, ALC, HIV + ALC, and normal controls (NC) were administered traditional and computerized tests of executive function and episodic memory. Test scores were expressed as age- and education-corrected Z-scores; selective tests were averaged to compute Executive Function and Episodic Memory Composite scores. Efficiency scores were calculated for tests with accuracy and response times. HIV, ALC, and HIV + ALC had lower scores than NC on Executive Function and Episodic Memory Composites, with HIV + ALC even lower than ALC and HIV on the Episodic Memory Composite. Impairments in planning and free recall of visuospatial material were observed in ALC, whereas impairments in psychomotor speed, sequencing, narrative free recall, and pattern recognition were observed in HIV. Lower decision-making efficiency scores than NC occurred in all 3 clinical groups. In ALC, age and lifetime alcohol consumption were each unique predictors of Executive Function and Episodic Memory Composite scores. In HIV + ALC, age was a unique predictor of Episodic Memory Composite score. Disease-specific and disease-overlapping patterns of impairment in HIV, ALC, and HIV + ALC have implications regarding brain systems disrupted by each disease and clinical ramifications regarding the complexities and compounded damping of cognitive functioning associated with dual diagnosis that may be exacerbated with aging.

The Treatment for Adolescents with Depression Study (TADS) database was analyzed to determine whether suicidal events (attempts and ideation) occurred early in treatment, could be predicted by severity of depression or other clinical characteristics, and were preceded by clinical deterioration or symptoms of increased irritability, akathisia, sleep disruption, or mania. TADS was a 36-week randomized, controlled clinical trial of pharmacologic and psychotherapeutic treatments involving 439 youths with major depressive disorder (DSM-IV criteria). Suicidal events were defined according to the Columbia Classification Algorithm of Suicidal Assessment. Patients were randomly assigned into the study between spring 2000 and summer 2003. Forty-four patients (10.0%) had at least 1 suicidal event (no suicide occurred). Events occurred 0.4 to 31.1 weeks (mean +/- SD = 11.9 +/- 8.2) after starting TADS treatment, with no difference in event timing for patients receiving medication versus those not receiving medication. Severity of self-rated pretreatment suicidal ideation (Suicidal Ideation Questionnaire adapted for adolescents score > or = 31) and depressive symptoms (Reynolds Adolescent Depression Scale score > or = 91) predicted occurrence of suicidal events during treatment (P < .05). Patients with suicidal events were on average still moderately ill prior to the event (mean +/- SD Clinical Global Impressions-Severity of Illness scale score = 4.0 +/- 1.3) and only minimally improved (mean +/- SD Clinical Global Impressions-Improvement scale score = 3.2 +/- 1.1). Events were not preceded by increased irritability, akathisia, sleep disturbance, or manic signs. Specific interpersonal stressors were identified in 73% of cases (N = 44). Of the events, 55% (N = 24) resulted in overnight hospitalization. Most suicidal events occurred in the context of persistent depression and insufficient improvement without evidence of medication-induced behavioral activation as a precursor. Severity of self-rated suicidal ideation and depressive symptoms predicted emergence of suicidality during treatment. Risk for suicidal events did not decrease after the first month of treatment, suggesting the need for careful clinical monitoring for several months after starting treatment.

To discusses the clinical effects of arthroscopy combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) technology in treating Schatzker IV tibial plateau fractures. From January 2012 to January 2016, 19 patients with Schatzker type IV tibial plateau fractures were treated with arthroscopy combined with minimally invasive technique including 12 males and 7 females with an average age of 46.5 years old ranging from 19 to 78 years old. Patients were suffering knee pain, swelling, flexion and extension limited, and other symptoms preoperative. Patients were followed up and assessed by Rasmussen knee function score. No infection, traumatic arthritis, and knee joint valgus occurred after operation. Nineteen cases were followed up for 12 to 24 months with an average of 18.6 months. Fracture healing time was 3 to 5 months with an average of 3.8 months. The knee pain and limited mobility improved significantly. The range of autonomic movement of joints was from 90 to 136 degrees. According to Rasmussen functional score criteria, the total score was 27.00±2.49, the result was excellent in 16 cases, good in 2 cases, fair in 1 case. Arthroscopic treatment for Schatzker type IV tibial plateau fractures combined with MIPPO can simultaneously treat internal structural injuries such as meniscus and other knee joints, with less trauma, fewer complications, and faster joint function recovery, but we must strictly grasp surgical indications and avoid expanding injuries.

Residents' understanding of diagnostic error may differ between countries. We sought to explore the relationship between diagnostic error knowledge and self-study, clinical knowledge, and experience. Our nationwide study involved postgraduate year 1 and 2 (PGY-1 and -2) Japanese residents. The Diagnostic Error Knowledge Assessment Test (D-KAT) and General Medicine In-Training Examination (GM-ITE) were administered at the end of the 2014 academic year. D-KAT scores were compared with the benchmark scores of US residents. Associations between D-KAT score and gender, PGY, emergency department (ED) rotations per month, mean number of inpatients handled at any given time, and mean daily minutes of self-study were also analyzed, both with and without adjusting for GM-ITE scores. Student's t test was used for comparisons with linear mixed models and structural equation models (SEM) to explore associations with D-KAT or GM-ITE scores. The mean D-KAT score among Japanese PGY-2 residents was significantly lower than that of their US PGY-2 counterparts (6.2 vs. 8.3, p < 0.001). GM-ITE scores correlated with ED rotations (≥6 rotations: 2.14; 0.16-4.13; p = 0.03), inpatient caseloads (5-9 patients: 1.79; 0.82-2.76; p < 0.001), and average daily minutes of self-study (≥91 min: 2.05; 0.56-3.53; p = 0.01). SEM revealed that D-KAT scores were directly associated with GM-ITE scores (ß = 0.37, 95% CI: 0.34-0.41) and indirectly associated with ED rotations (ß = 0.06, 95% CI: 0.02-0.10), inpatient caseload (ß = 0.04, 95% CI: 0.003-0.08), and average daily minutes of study (ß = 0.13, 95% CI: 0.09-0.17). Knowledge regarding diagnostic error among Japanese residents was poor compared with that among US residents. D-KAT scores correlated strongly with GM-ITE scores, and the latter scores were positively associated with a greater number of ED rotations, larger caseload (though only up to 15 patients), and more time spent studying.

Disability of the upper limb is one of the consequences of distal radius fracture (DRF). The outcome of DRF treatment is based on objective clinical variables, as strength or range of movement (ROM); sometimes these variables do not correlate with the functional level of the patient. The principal objective of our study was to assess the repercussion of conservative treatment of DRF on upper limb disability. This is a retrospective review of prospectively collected data. We collected data of 61 nonconsecutive DRFs treated conservatively from July 2007 to August 2008. Average Disabilities of the Arm, Shoulder and Hand (DASH) score before fracture was 20.8 points; average DASH score after the fracture was 42.6. There was a significant increase in the upper limb disability after 1 year of follow-up in the patients treated conservatively ( P < .001; size effect, 1.06). Average radial inclination, radial tilt, and radial length were 18.18°, 3.35°, and 5.76 mm, respectively. Average ROM for flexion-extension was 100.6° and for pronation-supination 144.0°. ROM for flexion-extension of the unaffected wrist was 128.2° and for pronation-supination 172.4°. We did not find any significant statistical correlation between the increase in disability and the decrease in the ROM ( P > .05). We did not find any significant statistical correlation between the increase in the disability and the worsening in the radiological parameters ( P > .05). Our results confirm the hypothesis that the conservative treatment of DRF produced an increase in the upper limb disability after 1 year of follow-up. Our study does not show a correlation between the increase in upper limb disability and the decrease in wrist ROM. Our study did not find a correlation between radiological measures and DASH scores.

Does Assessment Type Matter? A Measurement Invariance Analysis of Online and Paper and Pencil Assessment of the Community Assessment of Psychic Experiences (CAPE)

Background The psychometric properties of an online test are not necessarily identical to its paper and pencil original. The aim of this study is to test whether the factor structure of the Community Assessment of Psychic Experiences (CAPE) is measurement invariant with respect to online vs. paper and pencil assessment. Method The factor structure of CAPE items assessed by paper and pencil (N = 796) was compared with the factor structure of CAPE items assessed by the Internet (N = 21,590) using formal tests for Measurement Invariance (MI). The effect size was calculated by estimating the Signed Item Difference in the Sample (SIDS) index and the Signed Test Difference in the Sample (STDS) for a hypothetical subject who scores 2 standard deviations above average on the latent dimensions. Results The more restricted Metric Invariance model showed a significantly worse fit compared to the less restricted Configural Invariance model (χ2(23) = 152.75, p<0.001). However, the SIDS indices appear to be small, with an average of −0.11. A STDS of −4.80 indicates that Internet sample members who score 2 standard deviations above average would be expected to score 4.80 points lower on the CAPE total scale (ranging from 42 to 114 points) than would members of the Paper sample with the same latent trait score. Conclusions Our findings did not support measurement invariance with respect to assessment method. Because of the small effect sizes, the measurement differences between the online assessed CAPE and its paper and pencil original can be neglected without major consequences for research purposes. However, a person with a high vulnerability for psychotic symptoms would score 4.80 points lower on the total scale if the CAPE is assessed online compared to paper and pencil assessment. Therefore, for clinical purposes, one should be cautious with online assessment of the CAPE. PMID:24465389

Combined lateral elbow tendinosis (tennis elbow) and medial elbow tendinosis (golfer's elbow) can be a disabling condition that, if unresponsive to nonoperative treatments, may be effectively treated surgically. The authors are not aware of any study that reports the outcome of a combined operation for lateral and medial elbow tendinosis (country club elbow) performed in the same operative setting. Combined surgical treatment of country club elbow in the same operative setting has similar outcomes to those seen in the literature for single operative procedures. Case series; Level of evidence 4. Outcome measurements included the Numeric Pain Intensity Scale, the Nirschl tennis elbow scoring system, and the American Shoulder and Elbow Surgeons elbow form. Forty-eight patients (53 clinical elbows) were available by telephone, with a minimum time to follow-up of 5 years (range, 5-19 years; mean, 11.7 years). The average Nirschl tennis elbow score improved from 16.7 preoperatively to 70.8 postoperatively (P < .01). The average American Shoulder and Elbow Surgeons elbow score improved from 45.2 to 90.4 (P < .01). The Numeric Pain Intensity Scale score improved from 8.8 to 1.7 (P < .01). By the criteria of the Nirschl tennis elbow score, results were rated excellent in 38 elbows, good in 7 elbows, fair in 5 elbows, and poor in 3 elbows, with 85% (45 of 53) good to excellent results. Patient satisfaction with the surgery averaged 8.7 out of 10. Of the 46 patients who played sports, 44 (96%) reported returning to their sports. When nonoperative treatment of lateral and medial elbow tendinosis fails, combined surgical intervention via the Nirschl operative techniques for country club elbow is highly effective, with results similar to those of single-sided intervention.

Sleep abnormalities are considered an important feature of schizophrenia, yet convenient and reliable sleep monitoring remains a challenge. Smartphones offer a novel solution to capture both self-reported and objective measures of sleep in schizophrenia. In this three-month observational study, 17 subjects with a diagnosis of schizophrenia currently in treatment downloaded Beiwe, a platform for digital phenotyping, on their personal Apple or Android smartphones. Subjects were given tri-weekly ecological momentary assessments (EMAs) on their own smartphones, and passive data including accelerometer, GPS, screen use, and anonymized call and text message logs was continuously collected. We compare the in-clinic assessment of sleep quality, assessed with the Pittsburgh Sleep Questionnaire Inventory (PSQI), to EMAs, as well as sleep estimates based on passively collected accelerometer data. EMAs and passive data classified 85% (11/13) of subjects as exhibiting high or low sleep quality compared to the in-clinic assessments among subjects who completed at least one in-person PSQI. Phone-based accelerometer data used to infer sleep duration was moderately correlated with subject self-assessment of sleep duration (r = 0.69, 95% CI 0.23-0.90). Active and passive phone data predicts concurrent PSQI scores for all subjects with mean average error of 0.75 and future PSQI scores with a mean average error of 1.9, with scores ranging from 0-14. These results suggest sleep monitoring via personal smartphones is feasible for subjects with schizophrenia in a scalable and affordable manner. SMARTPHONES CAN TRACK SCHIZOPHRENIA-RELATED SLEEP ABNORMALITIES: Smartphones may one-day offer accessible, clinically-useful insights into schizophrenia patients' sleep quality. Despite the clinical relevance of sleep to disease severity, monitoring technologies still evade convenience and reliability. In search of a preferential method, a group of Harvard University researchers led by Patrick Staples investigated the validity of data collected via patients' own mobile phones. The team, with a cohort of 17 schizophrenia patients, compared the quality of data produced by smartphone sensors and smartphone-delivered questionnaires to that of an in-clinic evaluation. The results significantly showed that smartphone monitoring could generate information that approached the accuracy of in-clinic assessments. The team noted some areas for improvement; however, this study provides convincing justifications for further research into this non-invasive, low-cost, scalable method to monitor the sleep quality of schizophrenic patients.

To compare visual acuity (VA) scores after autorefraction vs manual refraction in eyes of patients with diabetes mellitus and a wide range of VAs. The letter score from the Electronic Visual Acuity (EVA) test from the electronic Early Treatment Diabetic Retinopathy Study was measured after autorefraction (AR-EVA score) and after manual refraction (MR-EVA score), which is the research protocol of the Diabetic Retinopathy Clinical Research Network. Testing order was randomized, study participants and VA examiners were masked to refraction source, and a second EVA test using an identical supplemental manual refraction (MR-EVAsuppl score) was performed to determine test-retest variability. In 878 eyes of 456 study participants, the median MR-EVA score was 74 (Snellen equivalent, approximately 20/32). The spherical equivalent was often similar for manual refraction and autorefraction (median difference, 0.00; 5th-95th percentile range, -1.75 to 1.13 diopters). However, on average, the MR-EVA scores were slightly better than the AR-EVA scores, across the entire VA range. Furthermore, the variability between the AR-EVA scores and the MR-EVA scores was substantially greater than the test-retest variability of the MR-EVA scores (P < .001). The variability of differences was highly dependent on the autorefractor model. Across a wide range of VAs at multiple sites using a variety of autorefractors, VA measurements tend to be worse with autorefraction than manual refraction. Differences between individual autorefractor models were identified. However, even among autorefractor models that compare most favorably with manual refraction, VA variability between autorefraction and manual refraction is higher than the test-retest variability of manual refraction. The results suggest that, with current instruments, autorefraction is not an acceptable substitute for manual refraction for most clinical trials with primary outcomes dependent on best-corrected VA.

To compare clinical efficacy of double titanium plate and clavicular hook plate for the treatment of Neer II distal clavicular fracture. From April 2013 to June 2015, 42 patients with Neer II distal clavicle fractures were non-randomly selected, including 25 males and 17 females. All patients were fresh closed fractures. Twenty patients were treated with double titanium plate with tight rope(group A), including 11 males and 9 females aged from 16 to 49 years old with an average age of(33.8±10.7) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.5±1.8) days. Twenty-two patients were treated with clavicle hook plate(group B), including 14 males and 8 females aged from 27 to 53 years old with an average age of (37.7±9.9) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.1±2.0) days. Operative time, blood loss, hospital stays and postoperative complications were observed and compared; fracture healing were compared among preoperative, postoperative at 1, 3 and 6 months; VAS and ASES scoring were used to evaluate shoulder function. All patients were followed up from 6 to 12 months with an average of 7.2 months. All incisions were healed at stage I. Blood loss in group A were less than that of group B( P <0.05); while there were no significant difference in hospital stays and operative time between two groups. No shoulder pain occurred in group A, 4 cases occurred shoulder pain in group B, and had significant difference. Fracture healing time ranged from 3 to 6 months with an average of 4.3 months. VAS score and ASES score in group A were higher than that of group B in pain, function and total score. Compared with clavicle hook plate, double titanium plate has advantages of shorter incision wound, less bleeding and simply operation, less complications, and could avoid pain for removing internal fixation. Over reduction of acromioclavicular joint during operation does not affect its superior curative effect. It is better choice for the treatment of Neer II distal clavicle fracture.

The outcome of treatment in 40 patients (42 knees) with chronic infections after total knee arthroplasty was reviewed. Eighteen knees were treated with a 2-stage reimplantation. Sixteen of these 18 knees were treated with antibiotic-containing beads between debridement and reimplantation, and 7 of these were also treated with antibiotics in the cement at reimplantation. Infection did not recur in any of these 18 knees. Clinically, the 2-stage reimplantation group averaged a score of 90 points on the Knee Society Clinical Rating System. Average function score was 86.5 points, with average range of motion from 2 degrees to 109 degrees. Sixteen knees were treated with an arthrodesis: 9 with a 1-stage technique with a uniplanar external fixator and 7 with a 2-stage technique with intramedullary nail internal fixation. Infection did not recur in 6 of 9 knees treated with the 1-stage technique, but only 2 had a solid arthrodesis. All 7 treated with the 2-stage intramedullary nail technique had no recurrence of infection and achieved a solid fusion. Reimplantation or arthrodesis was not attempted in 8 other knees because of recalcitrant infection, vascular complications, or medical infirmity. Of the 42 knees, 11 (26%) had a severely morbid outcome. The infection could not be eradicated in 7 knees: 6 required amputation and 1 had a solid fusion but chronic drainage. In 3 knees, the infection was cured but resection arthroplasties were required, and in 1 patient an amputation was needed as a result of an intraoperative vascular complication.

This study designed an arm-eye coordination test to investigate the effectiveness of the robot-aided rehabilitation for persons after stroke. Six chronic poststroke subjects were recruited to attend a 20-session robot-aided rehabilitation training of elbow joint. Before and after the training program, subjects were asked to perform voluntary movements of elbow flection and extension by following sinusoidal trajectories at different velocities with visual feedback on their joint positions. The elbow angle and the electromyographic signal of biceps and triceps as well as clinical scores were evaluated together with the parameters. Performance was objectively quantified by root mean square error (RMSE), root mean square jerk (RMSJ), range of motion (ROM), and co-contraction index (CI). After 20 sessions, RMSE and ROM improved significantly in both the affected and the unaffected side based on two-way ANOVA (P < 0.05). There was significant lower RMSJ in the affected side at higher velocities (P < 0.05). There was significant negative correlation between average RMSE with different tracking velocities and Fugl-Meyer shoulder-elbow score (P < 0.05). There was also significant negative correlation between average RMSE and average ROM (P < 0.05), and moderate nonsignificant negative correlation with RMSJ, and CI. The characterization of velocity-dependent deficiencies, monitoring of training-induced improvement, and the correlation between quantitative parameters and clinical scales could enable the exploration of effects of different types of treatment and design progress-based training method to accelerate the processes of recovery.

Femoroacetabular impingement (FAI) is considered a cause of labrochondral disease and secondary osteoarthritis. Nevertheless, the clinical syndrome associated with FAI is not fully characterized. We determined the clinical history, functional status, activity status, and physical examination findings that characterize FAI. We prospectively evaluated 51 patients (52 hips) with symptomatic FAI. Evaluation of the clinical history, physical exam, and previous treatments was performed. Patients completed demographic and validated hip questionnaires (Baecke et al., SF-12, Modified Harris hip, and UCLA activity score). The average patient age was 35 years and 57% were male. Symptom onset was commonly insidious (65%) and activity-related. Pain occurred predominantly in the groin (83%). The mean time from symptom onset to definitive diagnosis was 3.1 years. Patients were evaluated by an average 4.2 healthcare providers prior to diagnosis and inaccurate diagnoses were common. Thirteen percent had unsuccessful surgery at another anatomic site. On exam, 88% of the hips were painful with the anterior impingement test. Hip flexion and internal rotation in flexion were limited to an average 97° and 9°, respectively. The patients were relatively active, yet demonstrated restrictions of function and overall health. These data may facilitate diagnosis of this disorder. Level of Evidence: Level II, diagnostic study. See the Guidelines for Authors for a complete description of levels of evidence. PMID:19130160

It was decided that a study of the cold chain should be conducted in Chile in an effort to identify situations that could be corrected and to improve the technical and administrative development of the program. Specifically, study objectives were as follows: to determine the degree to which the EPI standards for procurement, receipt, transfer, control, maintenance, and distribution of vaccines were being met; to assess the turnover, knowledge, and training of auxiliary vaccination personnel against the relevant standards established for vaccine and cold chain management; to determine the antigenic potency of measles vaccine samples available at the time visits were made to local clinics, regional health storage sites, and the central supply facility; and to test a written instrument designed for the express purpose of assessing achievement of the first 2 objectives cited. The study sought to provide a descriptive assessment of work being performed at the central, regional, and local levels in the Metropolitan Region. The operating units involved included the airport and main supply center at the central level; the 7 storage facilities of the Metropolitan Region's 78 local clinics providing maternal and child health care. 40 clinics, selected by lot, represented 51% of the region's 78 clinics and provided coverage for 49% of the population assigned to the region's health services. The units studied failed to satisfy half the investigated Expanded Program for Immunization (EPI) standards, i.e., the average achievement rating of the 3 levels combined (49.3%) fell short of half the desired 100%. The airport unit met very few of the EPI implementation standards, scoring only 20% in this area. Deficiencies were found in systems for shipping vaccine in cold boxes, for making cold rooms permanently available, and for providing adequate vaccine transportation. The central supply facility, responsible for the purchase, storage, distribution, and maintenance of an adequate vaccine stock, had an achievement score of only 41%. The regional level, represented by the 7 storage facilities studied, obtained a lower overall achievement score than the other 2 levels and appears to be a high-risk link in the cold chain. The local level, represented by the 40 clinics studied, attained the highest average achievement score of any level (57%). Yet, serious deficiencies also emerged at this level, particularly regarding implementation and control activities. These deficiencies were aggravated by the fact that vaccines undoubtedly encounter a larger number of potentially damaging contingencies at the local level than they do elsewhere. Suggestions are made for overcoming these difficulties.

Total knee arthroplasty (TKA) is a common form of treatment to relieve pain and improve function in cases of rheumatoid arthritis (RA). Good clinical outcomes have been reported with a variety of TKA prostheses. The cementless Hi-Tech Knee II cruciate-retaining (CR)-type prosthesis, which has 6 fins at the anterior of the femoral component, posterior cruciate ligament (PCL) retention, flat-on-flat surface component geometry, all-polyethylene patella, strong initial fixation by the center screw of the tibial base plate, 10 layers of titanium alloy fiber mesh, and direct compression molded ultra high molecular weight polyethylene (UHMWPE), is appropriate for TKA in the Japanese knee.The present study was performed to evaluate the clinical results of primary TKA in RA using the cementless Hi-Tech Knee II CR-type prosthesis. We performed 32 consecutive primary TKAs using cementless Hi-Tech Knee II CR-type prosthesis in 31 RA patients. The average follow-up period was 8 years 3 months. Clinical evaluations were performed according to the American Knee Society (KS) system, knee score, function score, radiographic evaluation, and complications. The mean postoperative maximum flexion angle was 115.6°, and the KS knee score and function score improved to 88 and 70 after surgery, respectively. Complications, such as infection, occurred in 1 patient and revision surgery was performed. There were no cases of loosening in this cohort, and prosthesis survival rate was 96.9% at 12 years postoperatively. These results suggest that TKA using the cementless Hi-Tech Knee II CR-type prosthesis is a very effective form of treatment in RA patients at 5 to 12 years postoperatively. Further long-term follow-up studies are required to determine the ultimate utility of this type of prosthesis.

Cognitive profiles for pre-clinical Alzheimer disease (AD) can be used to identify groups of individuals at risk for disease and better characterize pre-clinical disease. Profiles or patterns of performance as pre-clinical phenotypes may be more useful than individual test scores or measures of global decline. To evaluate patterns of cognitive performance in cognitively normal individuals to derive latent profiles associated with later onset of disease using a combination of factor analysis and latent profile analysis. The National Alzheimer Coordinating Centers collect data, including a battery of neuropsychological tests, from participants at 29 National Institute on Aging-funded Alzheimer Disease Centers across the United States. Prior factor analyses of this battery demonstrated a four-factor structure comprising memory, attention, language, and executive function. Factor scores from these analyses were used in a latent profile approach to characterize cognition among a group of cognitively normal participants (N = 3,911). Associations between latent profiles and disease outcomes an average of 3 years later were evaluated with multinomial regression models. Similar analyses were used to determine predictors of profile membership. Four groups were identified; each with distinct characteristics and significantly associated with later disease outcomes. Two groups were significantly associated with development of cognitive impairment. In post hoc analyses, both the Trail Making Test Part B, and a contrast score (Delayed Recall - Trails B), significantly predicted group membership and later cognitive impairment. Latent profile analysis is a useful method to evaluate patterns of cognition in large samples for the identification of preclinical AD phenotypes; comparable results, however, can be achieved with very sensitive tests and contrast scores.

Neuroimaging holds the promise that it may one day aid the clinical assessment. However, the vast majority of studies using resting-state functional magnetic resonance imaging (fMRI) have reported average differences between Parkinson's disease (PD) patients and healthy controls, which do not permit inferences at the level of individuals. This study was to develop a model for the prediction of PD illness severity ratings from individual fMRI brain scan. The resting-state fMRI scans were obtained from 84 patients with PD and the Unified Parkinson's Disease Rating Scale-III (UPDRS-III) scores were obtained before scanning. The RVR method was used to predict clinical scores (UPDRS-III) from fMRI scans. The application of RVR to whole-brain resting-state fMRI data allowed prediction of UPDRS-III scores with statistically significant accuracy (correlation=0.35, P-value=0.001; mean sum of squares=222.17, P-value=0.002). This prediction was informed strongly by negative weight areas including prefrontal lobe and medial occipital lobe, and positive weight areas including medial parietal lobe. It was suggested that fMRI scans contained sufficient information about neurobiological change in patients with PD to permit accurate prediction about illness severity, on an individual subject basis. Our results provided preliminary evidence, as proof-of-concept, to support that fMRI might be possible to be a clinically useful quantitative assessment aid in PD at individual level. This may enable clinicians to target those uncooperative patients and machines to replace human for a more efficient use of health care resources. Copyright © 2016 Elsevier B.V. All rights reserved.

Electroconvulsive therapy (ECT) is generally recommended for treating catatonic schizophrenia. Non-catatonic schizophrenia patients also receive ECT. We compared the speed of response to ECT among patients with catatonic and other subtypes of schizophrenia. Consecutive schizophrenia patients referred for ECT within 3 months of starting antipsychotic treatment were studied (19 with catatonic and 34 with non-catatonic schizophrenia). Nurse's Observation Scale for Inpatient Evaluation (NOSIE-30) and Clinical Global Impression (CGI) were used to rate improvement. Referring psychiatrists stopped ECTs based on clinical impression of improvement. Total number of ECTs was taken as an indirect measure of speed of response. NOSIE-30 scores were compared using repeated measures analysis of variance. Catatonic schizophrenia patients required significantly fewer ECTs to achieve clinically significant improvement. There was a significant group x occasion effect in NOSIE scores, suggesting faster response to ECT in the catatonia group (F=41.6; P<0.001). Survival analysis suggested that patients with catatonic schizophrenia required significantly fewer ECTs (one less session on an average) to achieve clinical improvement (Log-rank statistic =5.31; P=0.02). Catatonic schizophrenia responds faster to ECT than non-catatonic schizophrenia. However, the magnitude of the difference is modest.

This paper is a report of an examination of the relationship between metrics of critical thinking skills and performance in simulated clinical scenarios. Paper and pencil assessments are commonly used to assess critical thinking but may not reflect simulated performance. In 2007, a convenience sample of 36 nursing students participated in measurement of critical thinking skills and simulation-based performance using videotaped vignettes, high-fidelity human simulation, the California Critical Thinking Disposition Inventory and California Critical Thinking Skills Test. Simulation-based performance was rated as 'meeting' or 'not meeting' overall expectations. Test scores were categorized as strong, average, or weak. Most (75.0%) students did not meet overall performance expectations using videotaped vignettes or high-fidelity human simulation; most difficulty related to problem recognition and reporting findings to the physician. There was no difference between overall performance based on method of assessment (P = 0.277). More students met subcategory expectations for initiating nursing interventions (P ≤ 0.001) using high-fidelity human simulation. The relationship between videotaped vignette performance and critical thinking disposition or skills scores was not statistically significant, except for problem recognition and overall critical thinking skills scores (Cramer's V = 0.444, P = 0.029). There was a statistically significant relationship between overall high-fidelity human simulation performance and overall critical thinking disposition scores (Cramer's V = 0.413, P = 0.047). Students' performance reflected difficulty meeting expectations in simulated clinical scenarios. High-fidelity human simulation performance appeared to approximate scores on metrics of critical thinking best. Further research is needed to determine if simulation-based performance correlates with critical thinking skills in the clinical setting. © 2010 The Authors.

Objective: To evaluate the efficacy of soft or implanted BAHA in the patients of Treacher Collins syndrome(TCS). Method: Six patients of TCS were studied. The Teber scoring system was used to evaluate the deformity degree. The air and bone auditory thresholds were assessed by auditory brain stem response(ABR). The infant-toddler meaningful auditory integration scale(IT-MAIS) was used to assess the auditory development at three time levels: baseline,3 months and 6 months. The hearing threshold and speech recognition score were measured under unaided and aided conditions. Result: The average score of deformity degree was 14.0±0.6. The TCOF1 gene was tested in two patients. The bone conduction hearing thresholds of patients was（18.0±4.5）dBnHL and the air conduction hearing thresholds was （70.5±7.0）dBnHL. The IT-MAIS total, detection and perception scores were improved significantly after wearing softband BAHA and approached the normal level in the 2 patients under 2 years old. The hearing thresholds of 6 patients in unaided and softband BAHA conditions were（65.8±3.8）dBHL and （30.0±3.2）dBHL ( P <0.01) respectively, and 1 implanted BAHA was 15 dBHL. The speech recognition scores of 3 patients in unaided and softband BAHA conditions were（31.7±3.5）% and（86.0±1.7）%( P <0.05) respectively, and 1 implanted BAHA was 96%. Conclusion: Whenever the patient was diagnosed as TCS by the clinical manifestations and genetic testing, BAHA system could help to rehabilitate the hearing to a normal condition.

The purpose of the present study was to retrospectively evaluate the outcomes of patients who underwent combined medial unicompartmental knee arthroplasty (UKA) and anterior cruciate ligament (ACL) reconstruction. The hypothesis was that this procedure would lead to a high success rate in patients affected by isolated medial unicompartmental osteoarthritis and concomitant ACL deficiency. Fourteen patients with primary ACL lesion and concomitant medial compartment symptomatic osteoarthritis treated from 2006 to 2010 were followed up for an average time of 26.7 months (SD 4.2). Assessment included KOOS score, Oxford Knee score, American Knee Society scores, WOMAC index of osteoarthritis, Tegner activity level and objective examination including instrumented laxity test with KT-1000 arthrometer. Radiological assessment was done with standard simple radiographs in order to get information about any presence of loosening of the components. KOOS score, OKS, WOMAC index and the AKSS improved significantly after surgery (p < 0.001). Regarding AKSS, improvement was noted both in the objective score and in the functional one (p < 0.001). There was no clinical evidence of instability in any of the knees as evaluated with clinical laxity testing. No pathologic radiolucent lines were observed around the components. In one patient signs of osteoarthritis in the lateral compartment were observed 28 months after surgery. UKA combined with ACL reconstruction is a valid therapeutic option for the treatment of combined medial unicompartmental knee osteoarthritis and ACL deficiency in young and active patients and confirms subjective and objective clinical improvement 2 years after surgery. The use of a fixed-bearing prosthesis represents a reliable feature as it allows to overcome problems of improper ligament tensioning during the implantation of the components. IV.

There is a need to find very early markers for pre-clinical Alzheimer's disease as interventions early in the disease process are thought to be most effective. The present study aimed to address the potential relation between cerebrospinal fluid (CSF) biomarkers and reduced cognitive function in a relatively young cohort of memory clinic patients with subjective cognitive decline. 122 patients (mean age 63 years) with subjective cognitive decline were recruited from two university memory clinics and followed for two years. The main finding was that the subgroup with objective memory decline during the study period had significantly higher T-tau at baseline than the group with improved memory. Baseline CSF variables showed a trend toward more pathological values in the patients with memory decline compared to those who improved or remained stable. The baseline memory score of those who declined was significantly better than the baseline score of those who improved over two years. The general trend for the whole group was improved memory and executive test scores. There were no differences in cognitive scores based on CSF quartiles at baseline, nor were there differences in cognitive outcome for patients with early amnestic mild cognitive impairment versus average cognitive function at baseline. The main finding that T-tau rather than amyloid-β was associated with memory decline do not support the prevailing opinion about the chain of events assumed to take place in Alzheimer's disease. In addition, memory decline was not associated with poor baseline memory score. Thus, a memory cut-off indicating low baseline memory would not would have identified the declining group.

This aim of this study was to assess the quality of life of Saudi female breast cancer patients and determine the effects of the sociodemographic and clinical characteristics on the quality of life of those patients. This study was designed as a cross-sectional study. The data were collected from 145 female cancer patients who were recruited from outpatient units in different clinical settings in Riyadh, Saudi Arabia, from September 2014 to February 2015. Questionnaires were distributed to the patients during their visits to the outpatient clinics after obtaining informed consent. Quality of life was assessed using a validated Arabic version of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life. Among functional scales, emotional functioning scored the highest (83.25 [95% CI 79.53-86.98]). The most distressing symptom on the symptom scale was insomnia (mean 84.14 [95% CI 79.95-88.32]), followed by appetite loss (mean 80.92 [95% CI 76.51-85.33]) and dyspnoea (mean 80.00 [95% CI 75.51-84.49]). Poor functioning was found in sexual enjoyment (mean 22.52 [95% CI 17.97-27.08]) while future perspective scored the highest (mean 76.32 [95% CI 70.52-82.12]). This study shows breast cancer survivors in Saudi had a low overall global quality of life. Saudi women showed average scores on all the functional scales but the emotional ones scored the highest. Insomnia, appetite loss, and dyspnoea were the distressing symptoms on symptom scales while future perspective domain scored the highest in item of QLQ-BR23.

Objective. To develop and implement an elective course on vitamins and minerals and their usefulness as dietary supplements. Design. A 2-credit-hour elective course designed to provide students with the most up-to-date basic and clinical science information on vitamins and minerals was developed and implemented in the doctor of pharmacy (PharmD) curriculum. In addition to classroom lectures, an active-learning component was incorporated in the course in the form of group discussion. Assessment. Student learning was demonstrated by examination scores. Performance on pre- and post-course surveys administered in 2011 demonstrated a significant increase in students’ knowledge of the basic and clinical science aspects of vitamins and minerals, with average scores increasing from 61% to 86%. At the end of the semester, students completed a standard course evaluation. Conclusion. An elective course on vitamin and mineral supplements was well received by pharmacy students and helped them to acquire knowledge and competence in patient counseling regarding safe, appropriate, effective, and economical use of these products.

The gap between domain experts and natural language processing expertise is a barrier to extracting understanding from clinical text. We describe a prototype tool for interactive review and revision of natural language processing models of binary concepts extracted from clinical notes. We evaluated our prototype in a user study involving 9 physicians, who used our tool to build and revise models for 2 colonoscopy quality variables. We report changes in performance relative to the quantity of feedback. Using initial training sets as small as 10 documents, expert review led to final F1scores for the "appendiceal-orifice" variable between 0.78 and 0.91 (with improvements ranging from 13.26% to 29.90%). F1for "biopsy" ranged between 0.88 and 0.94 (-1.52% to 11.74% improvements). The average System Usability Scale score was 70.56. Subjective feedback also suggests possible design improvements. © The Author 2017. Published by Oxford University Press on behalf of the American Medical Informatics Association. All rights reserved.

2009-12-01

The aim of this study was to investigate correlations between medical student scores on 4 examinations: the written examination, clinical clerkship examination, clinical skill assessment, and graduation examination. Scores for 51 students who entered Daegu Catholic Medical School in 2005 on the written examination, clinical clerkship examination, clinical skill assessment, and graduation examination were included. Correlations between the scores were analyzed statistically. The scores on the written examination showed a strong correlation with those of the clinical clerkship assessment (0.833) and graduation examination (0.821). The clinical clerkship assessment scores correlated significantly with graduation examination scores (0.907). In addition, clinical skill assessment scores correlated with the written examination (0.579), clinical clerkship examination (0.570), and graduation examination (0.465) scores. Overall, the correlation between the scores on the clinical clerkship examination and the written examination was more significant than the correlation between scores on the clinical clerkship examination and clinical skill assessment. Therefore, we need to improve the evaluation method for the clinical clerkship examination and clinical skill assessment.

Patients with type 1 diabetes mellitus (T1DM) who are able to adjust their insulin doses according to the carbohydrate content of a meal, as well as their blood glucose, are likely to have improved glycaemic control (Silverstein et al., 2005). With improved glycaemic control, patients have a lower risk of developing long-term microvascular complications associated with T1DM (Diabetes Control and Complications Trial Research Group, 1993). To assess the carbohydrate and insulin knowledge of patients attending our paediatric diabetes clinic at the University Hospital Limerick (UHL), the validated PedCarbQuiz (PCQ) was applied to our clinic population. This study was completed by applying a questionnaire called the PedCarbQuiz (PCQ) to children exclusively attending our paediatric diabetes clinic at UHL. Of the clinic's 220 patients, 81 participated in the study. The average total PCQ score (%) was higher in the continuous subcutaneous insulin infusion (CSII) group compared with the multiple daily insulin (MDI) injection user group (79.1 ± 12.1 versus 65.9 ± 6.6 p = 0.005). The CSII group also had a higher average carbohydrate score (%) compared with the MDI group (79.4 ± 12.4 versus 66.3 ± 16.2, p = 0.004). This study demonstrates that in a representative Irish regional paediatric T1DM clinic, knowledge of carbohydrates and insulin is better among patients treated with CSII compared with MDI. However, knowledge in both groups is poorer than in the original US sample. This study demonstrates that in a representative Irish regional paediatric T1DM clinic, knowledge of carbohydrates and insulin is poorer than in a US based sample, although this knowledge is better among patients treated with CSII compared with MDI. This highlights the need for improved resources for diabetes and carbohydrate counting education for patients with T1DM.

This study assessed the reproducibility and relative validity of an eight-item self-administered food frequency questionnaire (FFQ) on intake of sugared snacks in Ugandan schoolchildren. A 5-day precoded food behaviour checklist (FBC) was used as validation criteria. Sociodemographic correlates of a sum frequency sugar score were explored. The study was conducted in Kampala, Uganda, in 2004. Six hundred and fourteen schoolchildren (mean age 12.4 years) completed the FFQ on cakes/biscuits, chocolate, ice sticks, soft drinks, coffee, tea, sugared desserts and sweets/candies at school. They were examined clinically for dental caries. Forty students completed the FFQ twice, 1 week apart and 325 students completed the 5 day FBC at school. The mean decayed, missing and filled tooth index score was 0.98 (SD 1.6, range 0-15). Reproducibility scores (Cohen's kappa) for the sugar items ranged from 0.17 (ice sticks) to 0.55 (biscuits). No differences were seen between the average intakes at test and retest. Higher intake was reported in FFQ than in FBC across all sugar items. Crude agreement between students reporting intake at least 3-5 times a week/less than three times a week ranged from 50% to 55% (e.g. biscuits, chocolate) to 87% (tea). Spearman's correlation coefficients ranged from 0.14 (desserts) to 0.27 (sweets). anova revealed significant increase (P = 0.001) in the mean FBC sum scores by increasing quartiles of the FFQ sum scores. The average sum FFQ sugar scores were higher in girls than in boys and higher in older than in younger students. Fair reproducibility was established for the FFQ sugar items. The FFQ was acceptable in classifying individuals into broad categories of low and high sugar consumption.

This study was conducted with institutional review board approval and in compliance with HIPAA regulations. Written informed consent was obtained from all participants or the participants' legal guardians. Cross-validated discriminant analyses of MR imaging measures were performed to differentiate 164 Alzheimer disease (AD) cases from 203 healthy control cases. Separate analyses were performed by using data from MR images obtained at one time point or by combining single-time-point measures with 1-year change measures. Resulting discriminant functions were applied to 317 MCI cases to derive individual patient risk scores. Risk of conversion to AD was estimated as a continuous function of risk score percentile. Kaplan-Meier survival curves were computed for risk score quartiles. Odds ratios (ORs) for the conversion to AD were computed between the highest and lowest quartile scores. Individualized risk estimates from baseline MR examinations indicated that the 1-year risk of conversion to AD ranged from 3% to 40% (average group risk, 17%; OR, 7.2 for highest vs lowest score quartiles). Including measures of 1-year change in global and regional volumes significantly improved risk estimates (P = 001), with the risk of conversion to AD in the subsequent year ranging from 3% to 69% (average group risk, 27%; OR, 12.0 for highest vs lowest score quartiles). Relative to the risk of conversion to AD conferred by the clinical diagnosis of MCI alone, MR imaging measures yield substantially more informative patient-specific risk estimates. Such predictive prognostic information will be critical if disease-modifying therapies become available. http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101975/-/DC1. RSNA, 2011

Percutaneous aspiration of abscesses under ultrasonography (USG) and computer tomography (CT) scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD) has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome. Twenty-nine patients with dorsolumbar spondylodiscitis without gross neural deficit with psoas abscess of size >5 cm were selected for PCD. It was done as a day care procedure under local anesthesia. Sequentially, aspiration followed by guide pin-guided trocar and catheter insertion was done without image guidance. Culture sensitivity was done and chemotherapy initiated and catheter kept till the drainage was <10 ml for 48 hours. Outcome assessment was done with relief of pain, successful abscess drainage and ODI (Oswestry Disability Index) score at 2 years. PCD was successful in all cases. Back and radicular pain improved in all cases. Average procedure time was 24.30 minutes, drain output was 234.40 ml, and the drainage duration was 7.90 days. One patient required surgical stabilisation due to progression of the spondylodiscitis resulting in instability inspite of successful drainage of abscess. Problems with the procedure were noticed in six patients. Multiple attempts (n = 2), persistent discharge (n = 1) for 2 weeks, blocked catheter (n = 2) and catheter pull out (n = 1) occurred with no effect on the outcome. The average ODI score improved from 62.47 to 5.51 at 2 years. Clinically guided PCD is an efficient, safe and easy procedure in drainage of psoas abscess.

We analysed developmental outcomes from a clinical trial early in life and its follow-up at 10.7 years in 123 children with Down syndrome. To determine 1) strengths and weaknesses in adaptive functioning and motor skills at 10.7 years, and 2) prognostic value of early-life characteristics (early developmental outcomes, parental and child characteristics, and comorbidity) for later intelligence, adaptive functioning and motor skills. We used standardized assessments of mental and motor development at ages 6, 12 and 24 months, and of intelligence, adaptive functioning and motor skills at 10.7 years. We compared strengths and weaknesses in adaptive functioning and motor skills by repeated-measures ANOVAs in the total group and in children scoring above-average versus below-average. The prognostic value of demographics, comorbidity and developmental outcomes was analysed by two-step regression. Socialisation was a stronger adaptive skill than Communication followed by Daily Living. Aiming and catching was a stronger motor skill than Manual dexterity, followed by Balance. Above-average and below-average scoring children showed different profiles of strengths and weaknesses. Gender, (the absence or presence of) infantile spasms and particularly 24-month mental functioning predicted later intelligence and adaptive functioning. Motor skills, however, appeared to be less well predicted by early life characteristics. These findings provide a reference for expected developmental levels and strengths and weaknesses in Down syndrome. Copyright © 2016 Elsevier Ltd. All rights reserved.

To assess the theoretical knowledge and practical skills of parasitic diseases among technicians from disease control and prevention institutions. The Assessment on National Parasitic Disease Control and Prevention Techniques was organized in September, 2015. Together, 124 subjects from disease control and prevention institutions at province, prefecture or county levels in 31 provinces joined the assessment. A database was built consisting of subjects' basic information and assessment scores. Statistical analysis was used to analyze the scores by gender, age, professional title, institutions and places of participants. The average total score of all the subjects was 123.3, with a passing rate of 57.3%. The average scores of male subjects (48 subjects) and female subjects (76 subjects) were 125.9 and 121.7 respectively; the average scores of the subjects aged under 30 years (57 subjects), between 30 and 40 years (61 subjects) and above 40 years (6 subjects) were 119.6, 128.1 and 111.2 respectively; the average scores of persons with junior (94 subjects), intermediate (28 subjects) and senior (2 subjects) professional titles were 119.2, 135.9 and 140.5 respectively. The average theoretical assessment score of all the subjects was 61.9, with a passing rate of 62.9%. The average practical skill assessment score of all the subjects was 61.4, with a passing rate of 58.1%. The theoretical assessment results range widely. The theoretical knowledge results of technicians from disease control and prevention institutions are low in general. Therefore, the specific training based on daily work needs to be enhanced.

To assess sonographic and clinical features that might be used to predict infected bile and/or patient outcome from ultrasonography (US)-guided percutaneous cholecystostomy. Between February 1997 and August 2002 at one institution, 112 patients underwent US-guided percutaneous cholecystostomy (59 men, 53 women; average age, 69.3 years). All US images were scored on a defined semiquantitative scale according to preset parameters: (a) gallbladder distention, (b) sludge and/or stones, (c) wall appearance, (d) pericholecystic fluid, and (e) common bile duct size and/or choledocholithiasis. Separate and total scores were generated. Retrospective evaluation of (a) the bacteriologic growth of aspirated bile and its color and (b) clinical indices (fever, white blood cell count, bilirubin level, liver function test results) was conducted by reviewing medical records. For each patient, the clinical manifestation was classified into four groups: (a) localized right upper quadrant symptoms, (b) generalized abdominal symptoms, (c) unexplained sepsis, or (d) sepsis with other known infection. Logistic regression models, exact Wilcoxon-Mann-Whitney test, and the Kruskal-Wallis test were used. Forty-seven (44%) of 107 patients had infected bile. A logistic regression model showed that wall appearance, distention, bile color, and pericholecystic fluid were not individually significant predictors for culture-positive bile, leaving sludge and/or stones (P =.003, odds ratio = 1.647), common bile duct status (P =.02, odds ratio = 2.214), and total score (P =.007, odds ratio = 1.267). No US covariates or clinical indices predicted clinical outcome. Clinical manifestation was predictive of clinical outcome (P =.001) and aspirating culture-positive bile (P =.008); specifically, 30 (86%) of 35 patients with right upper quadrant symptoms had their condition improve, compared with one (7%) of 15 asymptomatic patients with other known causes of infection. US variables can be used to predict culture-positive bile but not patient outcome. Clinical manifestation is important because patients with right upper quadrant symptoms have the best clinical outcome. Copyright RSNA, 2004

-Assessment of customer satisfaction is a vital component of the laboratory quality improvement program. -To survey the level of physician satisfaction with hospital clinical laboratory services. -Participating institutions provided demographic information and survey results of physician satisfaction, with specific features of clinical laboratory services individually rated on a scale of 5 (excellent) to 1 (poor). -Eighty-one institutions submitted 2425 surveys. The median overall satisfaction score was 4.2 (10th percentile, 3.6; 90th percentile, 4.6). Of the 16 surveyed areas receiving the highest percentage of excellent/good ratings (combined scores of 4 and 5), quality of results was highest along with test menu adequacy, staff courtesy, and overall satisfaction. Of the 4 categories receiving the lowest percentage values of excellent/good ratings, 3 were related to turnaround time for inpatient "STAT" (tests performed immediately), outpatient STAT, and esoteric tests. The fourth was a new category presented in this survey: ease of electronic order entry. Here, 11.4% (241 of 2121) of physicians assigned below-average (2) or poor (1) scores. The 5 categories deemed most important to physicians included quality of results, turnaround times for inpatient STAT, routine, and outpatient STAT tests, and clinical report format. Overall satisfaction as measured by physician willingness to recommend their laboratory to another physician remains high at 94.5% (2160 of 2286 respondents). -There is a continued trend of high physician satisfaction and loyalty with clinical laboratory services. Physician dissatisfaction with ease of electronic order entry represents a new challenge. Test turnaround times are persistent areas of dissatisfaction, representing areas for improvement.

The main goal of this study was the development of a reliable intervention to overcome general procrastination orientated to college students, designed to be used in practical clinical work. The workshops involved six meetings based on behavioral and cognitive techniques, paradox intervention, and psychoeducation. 175 students participated voluntarily. Their procrastination levels were measured in a pretest, post-test, and a 3-month follow-up. After the first interview, the participants were randomly divided into three groups (Intervention A, Intervention B, and a control group with no intervention). There was a significant improvement after the intervention. After 3 months, the average score was still significantly lower than in the pretest, whereas the score of the control group remained unchanged. The participants in Workshop A scored significantly lower in the post-test than the ones in Workshop B. After 3 months, the participants in Workshop B scored significantly lower in the follow up. So both interventions resulted to be effective in reducing procrastination sustainably.

The purpose of this study was to compare muscle recovery in the lower extremities following the newly developed bi-cruciate substituting (BCS) to posterior stabilized (PS) total knee arthroplasty (TKA) in the Asian population. Forty-one knees in 41 patients undergoing BCS-TKA (41 female, average age: 71 ± 8.8) and 34 knees in 34 patients undergoing PS-TKA (33 female, average age: 73 ± 7.2) were included in this study. The maximum isometric power of the quadriceps and hamstring muscles was measured preoperatively, and at 1, 3, 6, and 12 months after surgery using a handheld dynamometer. Postoperative muscle recovery was calculated regarding preoperative muscle power as 100%. Pre- and postoperative range of knee motion, femorotibial angle, and clinical scores (Knee Society score and function score) were also compared. No significant difference in sex, age, preoperative quadriceps, or preoperative hamstring power was observed between the BCS and PS-TKA groups. When regarding the preoperative muscle power as 100%, quadriceps power at 1, 3, 6, and 12 months following BCS-TKA was 61.2 ± 22%, 86.3 ± 28.3%, 97 ± 27.4%, and 112.4 ± 30.8%, respectively. Quadriceps power at 1, 3, 6, and 12 months following PS-TKA was 72.4 ± 20.8%, 84 ± 16.9%, 95 ± 20.7%, and 110.8 ± 27%, respectively. Hamstring power at 1, 3, 6, and 12 months following BCS-TKA was 96.3 ± 30%, 111.4 ± 35%, 120 ± 37%, and 125 ± 31%, respectively. Hamstring power at 1, 3, 6, and 12 months following PS-TKA was 95 ± 25%, 112.4 ± 27%, 117 ± 38.5%, and 120.4 ± 18.5%, respectively. No significant difference in muscle power recovery was observed at 3 ( p  = 0.995), 6 ( p  = 0.944), and 12 ( p  = 0.917) months after surgery between the two groups. No significant difference of the clinical score was observed between the groups (Knee Society score: p  = 0.479, function score: p  = 0.342). No significant difference in muscle recovery and clinical score were observed between the BCS and PS-TKA groups. Longer follow-up is needed for the evaluation of efficacy of BCS-TKA in the Asian populations. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

The optimal treatment for distal clavicle nonunions remains unknown. Small series have reported outcomes following distal fragment excision and various fixation techniques. We present the clinical, radiographic and functional outcomes after superior plating or double (superior and anteroinferior) plating in combination with bone grafting as treatment for distal clavicle nonunions. We collected demographic and radiographic data from a consecutive series of ten patients with symptomatic nonunion of the distal clavicle treated since 1998. Functional outcomes were assessed, as well as the visual analogue scale (VAS) score. The mean clinical follow-up was 41.4 months (range of 12-158 months). The mean radiological follow-up was 30.6 months (range of 3-158 months). All nonunions healed as demonstrated by subsidence of clinical symptoms and radiographic criteria. The average time to union was 3.7 months (range of 2-8 months). The mean The Disabilities of the Arm, Shoulder and Hand (DASH) score was 11.9 (range of 0-62.5) and mean VAS score was 0.9 at follow-up. This study illustrates good clinical, radiologic and functional outcomes in ten patients with distal clavicle nonunion treated with superior or double (superior and anteroinferior) plating in combination with bone grafting. Double-plating can be considered an alternative to superior plating offering better resistance against the pulling effect of the arm with the use of smaller fixation plates.

We determined mid to long-term results of total elbow arthroplasty (TEA) by use of unlinked elbow prostheses with solid alumina ceramic trochleae, and ceramic ulnar stems (stemmed Kyocera type I; SKC-I) for patients with rheumatoid arthritis. Fifty-four elbows of 39 patients were available for detailed clinical and radiographic review after a follow-up period of at least 5 years. The mean follow-up period was 12.6 years (range 5-22 years). Clinical condition before and after surgery was assessed by use of a modified version of the Mayo Elbow Performance Score (MEPS; 0-100 points) and a Japan Orthopaedic Association Elbow score (JOA score; 0-100 points). The radiographs were reviewed and loosening was defined as a progressive radiolucent line >1 mm wide that was completely circumferential around the prosthesis. Clinical records of post-operative events affecting the elbows were used for survival analysis of the prostheses using the Kaplan-Meier method. The average modified MEPS and JOA scores improved significantly from 39.7 ± 14.3 to 44.7 ± 9.4, respectively, pre-operatively, to 89.7 ± 15.4 and 83.1 ± 12.8, respectively, post-operatively (P < 0.0001). The functional assessment score also improved from 4.9 ± 2.8 to 8.5 ± 3.3 points (P < 0.0001). With loosening or implant revision defined as end points, the likelihood of survival of the prosthesis for up to 20 years was 92.6% (95% confidence interval (CI), 85.6-100.0) or 86.3 % (95 % CI 75.0-97.6), respectively. Satisfactory clinical results were obtained after TEA using SKC-I prostheses, which provided excellent pain relief and functional range of motion. The results of our study reveal the high reliability over a long period of the cemented SKC-I prosthesis with an alumina ceramic component.

Convergence Insufficiency Symptom Survey Scores for Reading Versus Other Near Visual Activities in School-Age Children.

PubMed

Clark, Tiana Y; Clark, Robert A

2015-11-01

To measure the difference in Convergence Insufficiency Symptom Survey scores for reading vs favorite near visual activities. Comparative validity analysis of diagnostic tools. At a single clinical private practice, 100 children aged 9-18 with normal binocular vision were recruited to receive either the original survey emphasizing reading or a modified survey replacing "reading" with their favorite near activity. Average survey scores and subscores for questions emphasizing fatigue, discomfort, impaired vision, and cognitive performance were compared using t tests, while responses to individual questions were compared using Mann-Whitney U tests. The average reading survey score was significantly greater than the favorite near activity survey score (14.1 ± 11.5 vs 6.7 ± 5.8, P = .0001). The largest difference resulted from questions emphasizing cognitive performance (subscore 5.8 ± 4.3 vs 2.0 ± 2.1, P = .0000002), although significant differences were also found for fatigue (5.4 ± 3.8 vs 3.0 ± 2.7, P = .0003), discomfort (3.9 ± 4.6 vs 1.8 ± 2.2, P = .004), and impaired vision (3.2 ± 3.9 vs 1.8 ± 2.2, P = .02). Significant differences were found for 7 survey questions, with higher symptom scores for the reading survey in every case. Using survey scores ≥16 to diagnose convergence insufficiency, significantly more children taking the reading survey would have been diagnosed with convergence insufficiency than children taking the favorite near activity survey (19 of 50 [38%] vs 5 of 50 [10%], P = .001). By emphasizing reading, the Convergence Insufficiency Symptom Survey score significantly overestimates near visual symptoms in children with normal binocular vision compared with symptoms caused by preferred near activities that require similar amplitudes of accommodation and convergence.

To better understand verbal aggressiveness among physicians and trainees, including specialty-specific differences. The Infante Verbal Aggressiveness Scale (IVAS) was administered as part of a survey to 48 medical students, 24 residents, and 257 attending physicians. The 72 trainees received the IVAS and demographic questions, whereas the attending physicians received additional questions regarding type of practice, career satisfaction, litigation, and personality type. The IVAS scores showed high reliability (Cronbach α = 0.83). Among all trainees, 56% were female with mean age 28 years, whereas among attending physicians, 63% were male with mean age 50 years. Average scores of trainees were higher than attending physicians with corresponding averages of 1.88 and 1.68, respectively. Among trainees, higher IVAS scores were significantly associated with male sex, non-US birthplace, choice of surgery, and a history of bullying. Among attending physicians, higher IVAS scores were significantly associated with male sex, younger age, self-reported low-quality of patient-physician relationships, and low enjoyment talking to patients. General surgery and general internal medicine physicians were significantly associated with higher IVAS scores than other specialties. General practitioners (surgeons and medical physicians) had higher IVAS scores than the specialists in their corresponding fields. No significant correlation was found between IVAS scores and threats of legal action against attending physicians, or most personality traits. Additional findings regarding bullying in medical school, physician-patient interactions, and having a method to deal with inappropriate behavior at work were observed. Individuals choosing general specialties display more aggressive verbal communication styles, general surgeons displaying the highest. The IVAS scoring system may identify subgroups of physicians with overly aggressive (problematic) communication skills and may provide a backdrop for educating physician communicators. The relationship between verbal aggressiveness and efficacy of clinical communication merits inquiry. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc.

Since 1976, we have treated displaced intra-articular fractures of the calcaneus by open reduction through a lateral approach, temporary percutaneous fixation, and bone grafting. We assessed the results after a mean follow-up time of 98.9 (SD = 53) months in 30 patients with 35 fractures. In this report we review, clinically and radiologically, 35 fractures in 30 patients (five bilateral). Autografts was used in five cases (five patients) with an average follow-up of 145 months (SD = 43.7). Allografts were used in 19 cases (16 patients) with an average follow-up of 124 months (SD = 31.2), and hydroxyapatite was used in 11 cases (nine patients) with an average follow-up of 34 months (SD = 12.9). Clinical assessment was based on the Creighton-Nebraska Health Foundation scoring system and radiological measurements made from a lateral view. Seventy-seven percent of the patients had excellent or good clinical results and none had a poor result. Open reduction restored the "crucial angle" and the height of the calcaneus. The tuber joint angle described by Böhler was above 20 degrees in all the cases. There were no significant differences among the three groups of patients with regard to degree of residual pain, walking activities, range of subtalar movement, ability to return to their original jobs, hindfoot swelling, or change in footwear.

Objective Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. Methods This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and laboratory features including disease-specific autoantibodies determined by immunoprecipitation assays were analyzed. Results Videofluoroscopy swallow study (VFSS) was performed for all patients with clinical dysphagia (n = 13, 14.1%) but not for patients without clinical dysphagia. Typical findings of dysphagia (pharyngeal pooling, n = 11 and/or nasal regurgitation, n = 4) was detected by VFSS in all patients with clinical dysphagia. Eleven patients with dysphagia (84.6%) had anti-transcription intermediary factor 1γ (TIF-1γ) antibody. By univariate analysis, the average age and the male to female ratio, internal malignancy, and anti-TIF-1γ antibody were significantly higher and the frequency of interstitial lung diseases and manual muscle testing (MMT) scores of sternomastoid and dertoid muscles were significantly lower in patients with dysphagia than in patients without dysphagia. Among patients with anti-TIF-1γ antibody, the mean age, the ratios of male to female and internal malignancy were significantly higher and mean MMT scores of sternomastoid muscle were significantly lower in patients with dysphagia compared with patients without dysphagia. By multivariable analysis, the risk of dysphagia was strongly associated with the existence of internal malignancy and ant-TIF-1γ antibody and was also associated with reduced scores of manual muscle test of sternomastoid muscle. Dysphagia was markedly improved after the treatment against myositis in all 13 patients. Conclusion These findings indicate that dysphagia can develop frequently in patients with internal malignancy, anti-TIF-1γ antibody, or severe muscle weakness of sternomastoid muscle. PMID:27167831

Screening assessments for dysphagia are essential in neurodegenerative disease. Yet there are no purpose-built tools to quantify swallowing deficits at bedside or in clinical trials. A quantifiable, brief, easy to administer assessment that measures the impact of dysphagia and predicts the presence or absence of aspiration is needed. The Clinical Assessment of Dysphagia in Neurodegeneration (CADN) was designed by a multidisciplinary team (neurology, neuropsychology, speech pathology) validated against strict methodological criteria in two neurodegenerative diseases, Parkinson's disease (PD) and degenerative ataxia (DA). CADN comprises two parts, an anamnesis (part one) and consumption (part two). Two-thirds of patients were assessed using reference tests, the SWAL-QOL symptoms subscale (part one) and videofluoroscopic assessment of swallowing (part two). CADN has 11 items and can be administered and scored in an average of 7 min. Test-retest reliability was established using correlation and Bland-Altman plots. 125 patients with a neurodegenerative disease were recruited; 60 PD and 65 DA. Validity was established using ROC graphs and correlations. CADN has sensitivity of 79 and 84% and specificity 71 and 69% for parts one and two, respectively. Significant correlations with disease severity were also observed (p < 0.001) for PD with small to large associations between disease severity and CADN scores for DA. Cutoff scores were identified that signal the presence of clinically meaningful dysphagia symptomatology and risk of aspiration. The CADN is a reliable, valid, brief, quantifiable, and easily deployed assessment of swallowing in neurodegenerative disease. It is thus ideally suited for both clinical bedside assessment and future multicentre clinical trials in neurodegenerative disease.

To investigate the feasibility of a combined clinic-home intervention using a robotic elbow brace and, secondarily, to collect preliminary data on the efficacy of this clinic-home intervention. Nonrandomized pre-/postinterventional study. Outpatient clinic and participants' homes. Individuals at least 6 months after stroke (N=11; 5 women and 6 men; mean age, 51.7y; mean time since stroke, 7.6y; mean Fugl-Meyer Assessment of the Upper Extremity [FMA-UE] score, 22 of 66) were enrolled from the community. Participants received training in an outpatient clinic from an experienced occupational therapist to gain independence with use of the device (3-9 sessions) followed by a 6-week home program using the device at home. Five instruments were administered before and after the study intervention: Modified Ashworth Scale, Box and Blocks test, FMA-UE, Arm Motor Ability Test, and Motor Activity Log-Amount of Use and Motor Activity Log-How Well subscales (MAL-AOU, MAL-HW). Nine participants completed the study. Participants used the device on average 42.9min/d, 5.3d/wk. The FMA-UE (t=3.32; P=.01), MAL-AOU (t=4.40; P=.002), and MAL-HW (t=4.02; P=.004) scores showed statistically significant improvement from baseline to discharge; the MAL-AOU (t=2.61; P=.035) and MAL-HW (t=2.47; P=.043) scores were also significantly improved from baseline to 3-month follow-up. This combined clinic-home intervention was feasible and effective. Participants demonstrated improvements in arm impairment and self-reported use of the arm from baseline to discharge; they continued to report significant improvement in actual use of the arm at 3-month follow-up.

Arthroscopic repair of rotator cuff tears is a common procedure performed by orthopedic surgeons. There is a well-known incidence of up to 35% of bilateral rotator cuff tear disease in patients who have a known unilateral tear. The majority of the literature focuses on outcomes after unilateral surgery. The purpose of this study was to determine if there are clinical differences in shoulders of patients who underwent staged bilateral rotator cuff repairs during their lifetime. A retrospective review of all patients who underwent staged bilateral arthroscopic rotator cuff surgery at our institution was performed. All patients had at least 2 years of follow-up. Clinical outcome scores including the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation, and Rowe measures were obtained. A subset of patients returned for clinical and ultrasound evaluation performed by an independent fellowship-trained musculoskeletal radiologist. Overall, 110 shoulders in 55 patients, representing 68% of all eligible patients, participated. No clinical or statistical difference was found in any outcome measure. ASES scores averaged 86.5 (36.7-100) in the dominant shoulder compared with 89.6 (23.3-100) in the nondominant shoulder (P = .42). Ultrasound was available on 34 shoulders and showed complete healing rate of 88%. The shoulders with retearing of the rotator cuff (12%) demonstrated clinically relevant lower ASES scores (72.5) compared with shoulders with confirmed healed repairs (86.2; P = .2). Patients who undergo staged bilateral rotator cuff repair can expect to have similarly good clinical outcomes regardless of hand dominance or chronologic incidence with excellent healing rates in both shoulders.

This article explores specific aspects of self-reported clinical and research experience and their relationship to performance in medical training. This is a retrospective cohort study conducted at the Uniformed Services University. The American Medical College Application Service application was used to discern students' self-reported clinical and research experience. Two authors applied a classification scheme for clinical and research experience to the self-reported experiences. Study outcomes included medical school grade point average (GPA), U.S. Medical Licensing Examination (USMLE) scores, and intern expertise and professionalism scores. A linear regression analysis was conducted for each outcome while controlling for prematriculation GPA. Data were retrieved on 1,020 matriculants. There were several statistically significant but small differences across outcomes when comparing the various categories of clinical experience with no clinical experience. The technician-level experience group had a decrease of 0.1 in cumulative GPA in comparison to students without self-reported clinical experience (p = 0.004). This group also performed 5 points lower on the USMLE Step 2 than students who did not report clinical experience (p = 0.013). The various levels of self-reported research experience were unrelated to success in medical school and graduate medical education. These findings indicate that self-reported technician-level clinical experience is related to a small reduction in typically reported outcomes in medical school.

Clinical experience associated with the fear and anxiety of nursing students in the psychiatric unit. Mental health nursing instructors find it challenging to teach nursing students to deal with patients with mental disorders in an environment where they need to provide patient teaching and clinical decision-making based on evidence and new technology. To measure the effectiveness of clinical teaching of mental health courses in nursing using clinical supervision and Kirkpatrick's model evaluation in the psychiatry unit of Imam Reza Hospital, Bojnurd, Iran. This cross-sectional study was carried out from 2011 to 2016 on 76 nursing students from a university as part of a clinical mental health course in two semesters. The students were selected by a non-probable convenient sampling method. After completing their clinical education, each student responded to checklist questions based on the four-level Kirkpatrick's model evaluation and open questions relating to clinical supervision. Finally, all data was analyzed using the SPSS version 16. The students have evaluated clinical supervision as a useful approach, and appreciated the instructor's supportive behavior during teaching and imparting clinical skills. This has made them feel relaxed at the end of the clinical teaching course. In addition, in the evaluation through Kirkpatrick's model, more than 70% of the students have been satisfied with the method of conducting the teaching and average score of nursing students' attitude toward mental health students: Their mean self-confidence score was 18.33±1.69, and the mean score of their performance in the study was evaluated to be 93.74±5.3 from 100 points. The results of clinical mental health teaching through clinical supervision and Kirkpatrick's model evaluation show that the satisfaction, self-esteem, attitude, and skill of nursing students are excellent, thereby portraying the effectiveness of clinical teaching. But this program still needs to be reformed. To establish long-term goals and obtain knowledge and clinical skills of nursing, it is recommended to develop a curriculum and evaluate it appropriately.

Thrombocytopenia is common in hospitalized patients. Heparin-induced thrombocytopenia (HIT) is a life-threatening condition which can lead to extensive thrombosis. Diagnosis of HIT relies on clinical suspicion determined by 4T score and immunoassays through testing for anti-PF4/heparin antibodies. Clinical practice guidelines published by the American Society of Hematology in 2013 recommended use of the 4T score before ordering the immunoassays as a measure of pretest probability. The purpose of this study was to evaluate the utilization of 4T score before ordering anti-PF4/heparin antibodies at Unity Hospital. We did a retrospective chart review for patients who are 18 years or older, admitted to Unity Hospital between July 1, 2013, and December 31, 2014, and had anti-PF4/heparin antibodies ordered. Subjects who had prior history of HIT or had end-stage renal disease on hemodialysis were excluded. After calculating 4T score retrospectively, we calculated the proportion of patients who had 4T score documented prior to ELISA testing and proportion of ELISA tests, which were not indicated due to a 4T score less than or equal to 3 using Minitab 16. Review of 123 patients, with an average age of 69.4 years, showed that testing was indicated in 18 patients. Six subjects had positive results, and testing was indicated in all of them. 4T score was documented in three patients. This quality improvement study showed that 4T score documentation rate at Unity Hospital is 2.4%. Anti-PF4/heparin antibody testing was indicated in 14.6%. This test is being overused in thrombocytopenia work up at Unity Hospital, costing $9,345. The topic was reviewed for residents. A prompt and calculator for 4T score were added to electronic medical records before ordering the test as a step to improve high value care.

Total Hip Arthroplsty (THA) using uncemented stems is a popular practice in the last decades. The implant survivorship is crtitical and a less than 10% revision at 10 years is been propesed for commercialization and use. To analyse the clinicoradiological results of an uncemented hydroxiapatite covered wedge stem with a 5 years minimum follow up. Prospective study, patients aged from 21-75years were included. All patients received an Element stem (Exactech) and uncemented cup with crosslink poly and 32 mm metal head, and posterior approach with piriformis retention was used. Scheduled clinical and radiographic evaluation at 3 weeks, 3-6 month, year and subsequent years using Harris Hip Score and Merle d'Aubigné Postel. Intraoperative and during follow up complications were recorded. One hundred and fourteen total hip replacements in 104 patients: 54 females and 50 males (52%/48%). Follow-up of 5.7 years (range, 5-6.2years). Average age 56.8years (range, 42-75years). Clinical evaluation the Merle d'Aubigné score improved 6.8 points and from the initianl Harris Hip Score 47.3 to 93.1 points at last follow up. Radiographic evaluation shows osteointegration in all stems. And in 6 cases (5.3% at 3 months subsidence was detected, average 1.4 mm (range 0-2.6 mm) with no clinical manifestation, 3 cases of subsidence were associated to intraoperative fractures (1 greater trochanter and 2 in the calcar area, all resolved with wire cerclaje). Subjective evaluation: 86 cases (82.6%) excellent, 9 patients (8.6%) good, 6 cases (5.9%) satisfactory and 3 cases (2.9%) poor. All poor results linked to the intraoperative complications. No patient lost during follow up period. No femoral pain dislocation or aseptic or loosening detected. All implants were in situ at last follow up. The radiological results confirm the benefits of this type of stem with good osteointegration. The clinical and subjective results are promising. With good surgical technical and without complications the risk of aseptic loosening should be absent or minimal. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

SU-F-19A-09: Propagation of Organ at Risk Contours for High Dose Rate Brachytherapy Planning for Cervical Cancer: A Deformable Image Registration Comparison

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bellon, M; Kumarasiri, A; Kim, J

Purpose: To compare the performance of two deformable image registration (DIR) algorithms for contour propagation and to evaluate the accuracy of DIR for use with high dose rate (HDR) brachytherapy planning for cervical cancer. Methods: Five patients undergoing HDR ring and tandem brachytherapy were included in this retrospective study. All patients underwent CT simulation and replanning prior to each fraction (3–5 fractions total). CT-to-CT DIR was performed using two commercially available software platforms: SmartAdapt, Varian Medical Systems (Demons) and Velocity AI, Velocity Medical Solutions (B-spline). Fraction 1 contours were deformed and propagated to each subsequent image set and compared tomore » contours manually drawn by an expert clinician. Dice similarity coefficients (DSC), defined as, DSC(A,B)=2(AandB)/(A+B) were calculated to quantify spatial overlap between manual (A) and deformed (B) contours. Additionally, clinician-assigned visual scores were used to describe and compare the performance of each DIR method and ultimately evaluate which was more clinically acceptable. Scoring was based on a 1–5 scale—with 1 meaning, “clinically acceptable with no contour changes” and 5 meaning, “clinically unacceptable”. Results: Statistically significant differences were not observed between the two DIR algorithms. The average DSC for the bladder, rectum and rectosigmoid were 0.82±0.08, 0.67±0.13 and 0.48±0.18, respectively. The poorest contour agreement was observed for the rectosigmoid due to limited soft tissue contrast and drastic anatomical changes, i.e., organ shape/filling. Two clinicians gave nearly equivalent average scores of 2.75±0.91 for SmartAdapt and 2.75±0.94 for Velocity AI—indicating that for a majority of the cases, more than one of the three contours evaluated required major modifications. Conclusion: Limitations of both DIR algorithms resulted in inaccuracies in contour propagation in the pelvic region, thus hampering the clinical utility of this technology. Further work is required to optimize these algorithms and take advantage of the potential of DIR for HDR brachytherapy planning.« less

Validation of the Six Sigma Z-score for the quality assessment of clinical laboratory timeliness.

PubMed

Ialongo, Cristiano; Bernardini, Sergio

2018-03-28

The International Federation of Clinical Chemistry and Laboratory Medicine has introduced in recent times the turnaround time (TAT) as mandatory quality indicator for the postanalytical phase. Classic TAT indicators, namely, average, median, 90th percentile and proportion of acceptable test (PAT), are in use since almost 40 years and to date represent the mainstay for gauging the laboratory timeliness. In this study, we investigated the performance of the Six Sigma Z-score, which was previously introduced as a device for the quantitative assessment of timeliness. A numerical simulation was obtained modeling the actual TAT data set using the log-logistic probability density function. Five thousand replicates for each size of the artificial TAT random sample (n=20, 50, 250 and 1000) were generated, and different laboratory conditions were simulated manipulating the PDF in order to generate more or less variable data. The Z-score and the classic TAT indicators were assessed for precision (%CV), robustness toward right-tailing (precision at different sample variability), sensitivity and specificity. Z-score showed sensitivity and specificity comparable to PAT (≈80% with n≥250), but superior precision that ranged within 20% by moderately small sized samples (n≥50); furthermore, Z-score was less affected by the value of the cutoff used for setting the acceptable TAT, as well as by the sample variability that reflected into the magnitude of right-tailing. The Z-score was a valid indicator of laboratory timeliness and a suitable device to improve as well as to maintain the achieved quality level.

International prostate symptom score is a validated questionnaire used to evaluate the lower urinary tract symptoms in benign prostatic hyperplasia. Visual prostate symptom score is a new simplified symptom score with pictograms to evaluate the same. We evaluated the correlation of visual prostate symptom score with international prostate symptom score and uroflowmetry parameters in Nepalese male patients with lower urinary tract symptoms. Male patients aged ≥40 years attending the Urology clinic were enrolled in the study. They were given international prostate symptom score and visual prostate symptom score questionnaires to complete providing assistance whenever needed. Demographic data, examination findings and uroflowmetry parameters were noted. Correlation and regression analysis was used to identify correlation of the two scoring systems and uroflowmetry parameters. Among the 66 patients enrolled, only 10 (15.15%) patients were able to understand English language. There was a statistically significant correlation between total visual prostate symptom score and international prostate symptom score (r= 0.822; P<0.01). The correlations between individual scores of the two scoring systems related to force of urinary stream, frequency, nocturia and quality of life were also statistically significant. There was also a statistically significant correlation of both scores with maximum flow rate and average flow rate. There is a statistically significant correlation of visual prostate symptom score with international prostate symptom score and uroflowmetry parameters. IPSS can be replaced with simple VPSS in evaluation of lower urinary tract symptoms in elderly male patients.

Comparative responsiveness and minimal clinically important differences for idiopathic ulnar impaction syndrome.

PubMed

Patient-reported questionnaires have been widely used to predict symptom severity and functional disability in musculoskeletal disease. Importantly, questionnaires can detect clinical changes in patients; however, this impact has not been determined for ulnar impaction syndrome. We asked (1) which of Patient-Rated Wrist Evaluation (PRWE), DASH, and other physical measures was more responsive to clinical improvements, and (2) what was the minimal clinically important difference for the PRWE and DASH after ulnar shortening osteotomy for idiopathic ulnar impaction syndrome. All patients who underwent ulnar shortening osteotomy between March 2008 and February 2011 for idiopathic ulnar impaction syndrome were enrolled in this study. All patients completed the PRWE and DASH questionnaires, and all were evaluated for grip strength and wrist ROM, preoperatively and 12 months postoperatively. We compared the effect sizes observed by each of these instruments. Effect size is calculated by dividing the mean change in a score of each instrument during a specified interval by the standard deviation of the baseline score. In addition, patient-perceived overall improvement was used as the anchor to determine the minimal clinically important differences on the PRWE and DASH 12 months after surgery. The average score of each item except for wrist flexion and supination improved after surgery. The PRWE was more sensitive than the DASH or than physical measurements in detecting clinical changes. The effect sizes and standardized response means of the outcome measures were as follows: PRWE (1.51, 1.64), DASH (1.12, 1.24), grip strength (0.59, 0.68), wrist pronation (0.33, 0.41), and wrist extension (0.28, 0.36). Patient-perceived overall improvement and score changes of the PRWE and DASH correlated significantly. Minimal clinically important differences were 17 points (of a possible 100) for the PRWE and 13.5 for the DASH (also of 100), and minimal detectable changes were 7.7 points for the PRWE and 9.3 points for the DASH. Although the PRWE and DASH were highly sensitive to clinical changes, the PRWE was more sensitive in terms of detecting clinical changes after ulnar shortening osteotomy for idiopathic ulnar impaction syndrome. A minimal change of 17 PRWE points or 13.5 DASH points was necessary to achieve a benefit that patients perceived as clinically important. The minimal clinically important differences using these instruments were higher than the values produced by measurement errors.
