Diagnostic Accuracy of Clinical Tests for Assessment of Hamstring Injury: A Systematic Review
Authors: Reiman Michael P. , Loudon Janice K. , Goode Adam P. 
Published: February 2013

Study Design Systematic literature review. Background The diagnosis of a hamstring injury has traditionally relied on various clinical measures (eg, palpation, swelling, manual resistance), as well as the use of diagnostic imaging. But a few studies have suggested the use of specific clinical tests that may be helpful for the diagnostic process. Objective To summarize the current literature on the diagnostic accuracy of orthopaedic special tests for hamstring injuries and to determine their clinical utility. Methods A computer-assisted literature search of the MEDLINE, CINAHL, and Embase databases (along with a manual search of grey literature) was conducted using key words related to diagnostic accuracy of hamstring injuries. To be considered for inclusion in the review, the study required (1) patients with hamstring or posterior thigh pain; (2) a cohort, case-control, or cross-sectional design; (3) inclusion of at least 1 clinical examination test used to evaluate hamstring pathology; (4) comparison against an acceptable reference standard; (5) reporting of diagnostic accuracy of the measures (sensitivity [SN], specificity [SP], or likelihood ratios); and (6) publication in English. SN, SP, and positive and negative likelihood ratios were calculated for each diagnostic test. Results The search strategy identified 602 potential articles, of which only 3 articles met the inclusion criteria, with only 1 of these 3 articles being of high quality. Two of the studies investigated a single special test, whereas the third article examined a composite clinical assessment employing various special tests. The SN values ranged from 0.55 (95% confidence interval [CI]: 0.46, 0.69) for the active range-of-motion test to 1.00 (95% CI: 0.97, 1.00) for the taking-off-the-shoe test. The SP values ranged from 0.03 (95% CI: 0.00, 0.22) for the composite clinical assessment to 1.00 (95% CI: 0.97, 1.00) for the taking-off-the-shoe test, active range-of-motion test, passive range-of-motion test, and resisted range-of-motion test. The use of a single special test demonstrated stronger SP than SN properties, whereas the composite clinical assessment demonstrated stronger SN than SP properties. Conclusion Very few studies have investigated the utilization of clinical special tests for the diagnosis of hamstring injuries. Further studies of higher quality design are suggested prior to advocating independent clinical utilization of these special tests. Level of Evidence Diagnosis, level 3b.

Influence of snow type and temperature on snow viscosity
Authors: Delmas Louis 
Published: February 2013

AbstractThree spontaneous avalanches were observed in Lia, Longyearbyen, Svalbard, each occurring naturally under similar temperature conditions. Automatic measurements of temperature inside the snowpack led to examination of the triggering of avalanches in cold conditions following a rapid drop in temperature. The mechanical properties of ice depend on the slab temperature and I ask: could a rapid temperature change affect the mechanical properties differently considering a slab consisting of (1) rounded grains or (2) faceted grains? Snow is considered as a foam of ice crystals, and triaxial deformation tests are performed at constant strain rate to examine the influence of temperature and grain type on the mechanical properties. Although the snow densities in the two sample sets were almost identical, some differences due to grain type were observed. In particular, the set with faceted grain snow started to flow at higher stresses than the set with rounded grains.

Positioning Evaluation of Corrective Osteotomy for the Malunited Radius: 3-D CT Versus 2-D Radiographs
Authors: Vroemen Joy C. , Dobbe Johannes G.G. , Strackee Simon D. , Streekstra Geert J. 
Published: February 2013

The authors retrospectively investigated the postoperative position of the distal radius after a corrective osteotomy using 2-dimensional (2-D) and 3-dimensional (3-D) imaging techniques to determine whether malposition correlates with clinical outcome. Twenty-five patients who underwent a corrective osteotomy were available for follow-up. The residual positioning errors of the distal end were determined retrospectively using standard 2-D radiographs and 3-D computed tomography evaluations based on a scan of both forearms, with the contralateral healthy radius serving as reference. For 3-D analysis, use of an anatomical coordinate system for each reference bone allowed the authors to express the residual malalignment parameters in displacements (Δx, Δy, Δz) and rotations (Δφx, Δφy, Δφz) for aligning the affected bone in a standardized way with the corresponding reference bone. The authors investigated possible correlations between malalignment parameters and clinical outcome using patients’ questionnaires.
Two-dimensional radiographic evaluation showed a radial inclination of 24.9°±6.8°, a palmar tilt of 4.5°±8.6°, and an ulnar variance of 0.8±1.7 mm. With 3-D analysis, residual displacements were 2.6±3 (Δx), 2.4±3 (Δy), and −2.2±4 (Δz) mm. Residual rotations were −6.2°±10° (Δφx), 0.3°±7° (Δφy), and −5.1°±10° (Δφz). The large standard deviation is indicative of persistent malalignment in individual cases. Statistically significant correlations were found between 3-D rotational deficits and clinical outcome but not between 2-D evaluation parameters. Considerable residual malalignments and statistically significant correlations between malalignment parameters and clinical outcome confirm the need for better positioning techniques.

To the authors’ knowledge, no comparative studies exist of venous thromboembolism (VTE) based on different pathologies, surgical procedures, or spinal levels after spinal surgery. The authors prospectively investigated VTE after elective spinal surgery.
The study comprised 4 patient groups. Group 1 comprised 79 patients with lumbar spinal stenosis treated with posterior decompression without fusion; group 2 comprised 90 patients with lumbar or lower thoracic degenerative disease treated with instrumentation for spine fusion; group 3 comprised 89 patients with cervical degenerative disease treated with posterior decompression or instrumentation for fusion; and group 4 comprised 82 patients with spinal tumors treated with total spondylectomy or piecemeal excision with stabilization. Deep venous thrombosis (DVT) and pulmonary thromboembolism (PTE) screening was performed for all 340 patients 7 to 10 days postoperatively. Binomial logistic regression analysis was used to assess the association of risk factors. The incidence of VTE was 15.2% in group 1, 13.3% in group 2, 4.5% in group 3, and 22.0% in group 4. The overall incidence of PTE was 2.9% (10/340 patients). Of the 10 cases of PTE, 2 were symptomatic and 8 were asymptomatic. No DVT occurred in 6 of 10 PTE-positive patients. Multivariate analysis showed that spinal tumors, neurologic deficits, and advanced age were risk factors for VTE. Spinal tumor surgery carries a high risk of critical VTE, whereas cervical spine surgery carries a low risk. No DVT occurred in 60% of PTE-positive patients. This result indicates that screening for PTE is also needed in patients who are at high risk for VTE.

Hip fracture is becoming a major public health concern, with associated mortality and morbidity particularly in the elderly. This study aims to investigate factors (i.e. patient factors and hospital variables) associated with increased risk for delaying surgery after hip fractures, and to assess whether and to what extent timing was associated with mortality risk. All patients aged 65 and over, resident in Emilia Romagna Region (Italy) and admitted to hospital for hip fracture (2009 - 2010) were selected. Data on surgical delay were adjusted using multilevel logistic regression model. A Cox proportional hazard model was fitted to a propensity score matched sample to assess mortality between delayed and early treated patients. Of the 10, 995 patients included (mean age: 83.3 years), 44.9% underwent surgery within 2 days. Significant risk factors for delayed surgery were: gender (OR: 1.16), comorbidity (OR: 1.29), anticoagulant (OR: 7.64), antiplatelet medication (OR: 2.43), type of procedure (OR: 1.37) and day of admission (OR: Thu-Fri: 6.05; Sat-Sun: 1.17). Type of hospital and annual volume of hip fracture surgeries were not sufficient to explain hospital variability. A significant difference in mortality rate between early and delayed surgery emerged six months post surgery.
Urinary Retention Due to Benign Tumor of the Bladder Neck in a Woman; A Rare Case of Papillary Cystitis
Authors: Stamatiou Kostantinos 
Published: February 2013

Background Urinary retention (UR) is not common in women. There are numerous causes now recognized in women, broadly categorized as infective, pharmacological, neurological, anatomical, myopathic and functional. As opposed to the male, obstructive UR is unusual in women. Methods A 56-year-old woman presented with urinary retention. She reported difficulty in urination for more than 15 days. She had no history of urinary tract infection, bladder surgery and catheterization. Her physical examination revealed a soft tissue mass obstructing the external orifice of the urethra. After its partial removal the patient regained her ability to urinate. Results The patient underwent urological investigation. Ultrasound examination of the urinary system was normal. Cystoscopic examination revealed a papillary lesion with broad base floating along the bladder neck. The patient underwent transurethral resection of the bladder tumor. Discussion Pathological examination diagnosed papillary cystitis. She was scheduled for a regular follow-up with urine cytology, ultrasound and cystoscopy. One year after diagnosis the patient remains free of symptoms and no recurrence was observed. Conclusions Papillary and polypoid cystitis are benign lesions, however under certain circumstances they should be considered in the differential diagnosis of transitional cell carcinoma of the bladder. Lack of the prominent inflammation and edema that characterizes both papillary and polypoid cystitis, and absence of a history of recent bladder catheterization and presence of vesical fistula may facilitate the decision to biopsy the lesion. To our knowledge, this is the first case of papillary cystitis presenting with urinary retention in a woman to be reported in the literature.
Evidence of An Archaic Dam In A Carolina Bay: The Sewee Shell Ring, South Carolina
Authors: Middaugh Douglas P. 
Published: February 2013

Abstract
The Sewee shell ring is part of a complex water gathering system built in a Carolina bay designated as Oak Bay. The seaward boundary of the shell ring, the sand rim of Oak Bay, and a surface exposed aquiclude/aquitard stratum are concordant. A Slough, adjacent to the Sewee shell ring structure, is characterized by a perennial freshwater stream flowing into it. A Slough shell structure is located near the seaward end of the Slough. This shell structure is perpendicular to the long axis of the Slough. It was built on the aquiclude/aquitard stratum of Oak Bay. Measurement of unconfined sub-surface water heights, seaward of the Slough shell structure, indicated no trends in retention of freshwater at low or high tide during sequential drought and rainy periods, Water heights, in contrast, landward of the Slough shell structure at low and high tide were higher during the rainy, compared to the drought period. Salinities of unconfined sub-surface water samples also indicated retention of freshwater landward of the Slough shell structure, but not seaward of it. These findings indicate that the Slough shell structure could have been part of an archaic dam, designed and located to retain surface and sub-surface freshwater in the Slough. This freshwater then flowed across a series of weirs and into an Arena-tank.
Nordic contemporary art education and the environment: Constructing an epistemological platform for Art Education for Sustainable Development (AESD)
Authors: Illeris Helene 
Published: February 2013

How can art educators address questions of environmental sustainability, accepting to be ethically normative but avoiding becoming dogmatic? How can the complex ‘pool’ of knowledge generated in and through art education research become useful in working with these questions, which many of us find overwhelmingly difficult? AESD – Art Education for Sustainable Development – is a concept coined for this article with the intention of bringing environmental problems onto the agenda. In an attempt to provoke the necessary discussion about environmental sustainability in art education, the article examines selected texts from recent Nordic research in order to build an ‘epistemological platform’ that might function as a research-based ‘tool’ for discussing environmental issues. The article is organized in four sections, which refer to the four ’cornerstones’ of the platform, where each cornerstone corresponds to a recent current in art education. These currents, as defined by the author, are: critical art education, poststructuralist strategies, visual culture pedagogy, and community oriented visual practices. Using selected Nordic texts as material for the analysis, the epistemological perspective of each current is briefly presented and its relationship to evironmental questions is discussed. In the final discussion, eight keywords are presented: praxis, change, performance, reflexivity, visuality, event, situatedness and collaboration. When put together, these concepts offer a dynamic picture of the ‘pool’ of ideas offered by contemporary Nordic and international research, which will be useful for ‘performing’ AESD both as teaching practices and as research.
Similarities in Contexts and Theorizing: Professionalism and Inequality
Authors: Evetts Julia 
Published: February 2013

For a long time sociologists of professions have differentiated Anglo-American and European contexts for professional work. The presentation will address this distinction and argue that processes of convergence now render such differences somewhat obsolete except in historical accounts. In addition the convergence of professional systems and of regulatory states is also generating new inequalities both between professional groups themselves as well as within the organizations in which practitioners work. The presentation will examine convergences and inequalities at the macro level. Aspects to be considered include the changing role of the nation-state, the internationization of markets, the increased significance of the work organization and the different logics of professionalism. The extent of convergence and continuing divergences will be explored and social inequalities indicated. Macro-level processes and procedures including the growth of ‘hybrid’ organizations and new forms of managerialism can constitute new types of inequality and forms of stratification both within and between professions. The historical starting points within Europe and nation-state differences in professional systems make convergences and inequalities both highly complex and extremely variable.
Validation of the Dutch Reactive Proactive Questionnaire (RPQ): Differential Correlates of Reactive and Proactive Aggression From Childhood to Adulthood
Authors: Cima Maaike , Raine Adrian , Meesters Cor , Popma Arne 
Published: February 2013

AbstractThis study reports reliability and validity of the Dutch Reactive‐Proactive Aggression Questionnaire (RPQ). In total, 845 participants completed the RPQ along with other measures of aggression. Groups consisted of non‐offender participants, criminal offenders, youngsters (age 6–18), and adults (age above 18). Test–retest stability in a subsample of 324 childhood arrestees was good (all ICC's > 0.41). A confirmatory factor analysis supported the same two‐factor structure as in the original RPQ. Convergent validity was adequate (all r's > 0.16). Moreover, results demonstrated that the proactive and reactive subscales were differentially related to measurements of callousness and impulsiveness, respectively. Criterion validity was shown in that non‐offender subjects demonstrated significantly lower RPQ scores than offender samples. Finally, construct validity was demonstrated in that violent offenders showed higher aggression scores than non‐violent offenders. Proactive aggression showed different developmental trajectories within non‐offender versus criminal samples, indicating that this form of aggression may be more pathological. Aggr.

The Roles of Antisocial History and Emerging Adulthood Developmental Adaptation in Predicting Adult Antisocial Behavior
Authors: Alink Lenneke R. A. , Egeland Byron 
Published: February 2013

AbstractDifferent trajectories of antisocial behavior in childhood and adolescence have been identified by several researchers. However, more needs to be known about the development of antisocial behavior in adulthood and about factors that account for continuity and change. In this study, we investigated the developmental course into adulthood of different trajectories of antisocial behavior in childhood and adolescence. Second, we examined the role of developmental adaptation in emerging adulthood in accounting for the continuity and change of antisocial behavior. The participants (N = 162) were drawn from an ongoing 28‐year longitudinal study. Trajectory groups (EOP: Early Onset/Persistent, n = 30; AO: Adolescent Onset, n = 32; Other, n = 100) were based on measures of externalizing behavior assessed at six time points in childhood and adolescence. Through interviews and questionnaires in adulthood, the quality of romantic relationships and the participants' work ethic (age 23), duration of unemployment (between ages 23 and 26 years), the level of externalizing problems (ages 23 and 26), and the number of antisocial personality disorder symptoms (age 28) were assessed. Results indicated that individuals in the EOP group showed the highest levels of antisocial behavior throughout emerging and early adulthood. Negative experiences in the work and romantic relationship domains was related to the continuity of antisocial behavior in the EOP group. For the AO group, a shorter duration of unemployment was related to lower levels of antisocial behavior. This study shows that early history plays an important role in the development of antisocial behavior and in the way developmental adaptation in emerging adulthood accounts for continuity and change of antisocial behavior.

Is Relational Aggression Part of the Externalizing Spectrum? A Bifactor Model of Youth Antisocial Behavior
Authors: Tackett Jennifer L. , Daoud Stephanie L. S. B. , De Bolle Marleen , Burt Sybil Alexandra 
Published: February 2013

AbstractThe primary purpose of the present study was to examine support for the inclusion of relational aggression (RAgg) alongside physical aggression (Agg) and rule‐breaking behaviors (RB) as a subfactor of antisocial behavior (ASB). Caregiver reports were collected for 1,087 youth (48.9% male) ages 6–18. Results indicated that all three subfactors of ASB demonstrated substantial loadings on a general ASB factor. Using a bifactor model approach, specific factors representing each ASB subfactor were simultaneously modeled, allowing for examination of common and specific correlates. At the scale level, results demonstrated consistently strong connections with high Neuroticism and low Agreeableness across all 3 ASB subfactors, a pattern which was replicated for the general ASB factor in the bifactor approach. Specific factors in the bifactor model demonstrated connections with personality and psychopathology correlates, primarily for Agg. These findings provide some support for an overall grouping of RAgg with other ASB subfactors in youth, and further distinguish Agg as potentially representing a more potent variant of youth ASB relative to both RB and RAgg.

AbstractSuccessful nanobiotechnology implementation largely depends on control over the interfaces between inorganic materials and biological molecules. Controlling the orientations of biomolecules and their spatial arrangements on the surface may transform many technologies including sensors, to energy. Here, we demonstrate the self‐organization of L‐lactate dehydrogenase (LDH), which exhibits enhanced enzymatic activity and stability on a variety of gold surfaces ranging from nanoparticles to electrodes, by incorporating a gold‐binding peptide tag (AuBP2) as the fusion partner for Bacillus stearothermophilus LDH (bsLDH). Binding kinetics and enzymatic assays verified orientation control of the enzyme on the gold surface through the genetically incorporated peptide tag. Finally, redox catalysis efficiency of the immobilized enzyme was detected using cyclic voltammetry analysis in enzyme‐based biosensors for lactate detection as well as in biofuel cell energy systems as the anodic counterpart. Our results demonstrate that the LDH enzyme can be self‐immobilized onto different gold substrates using the short peptide tag under a biologically friendly environment. Depending on the desired inorganic surface, the proposed peptide‐mediated path could be extended to any surface to achieve single‐step oriented enzyme immobilization for a wide range of applications.
