Background Hematoma expansion is a major predictor of morbidity and mortality after intracerebral hemorrhage (ICH). Both baseline hematoma volume and the CT-angiogram (CTA) spot sign predict hematoma expansion. Because the CTA spot sign may represent foci of active hemorrhage, we hypothesized that patients with smaller baseline hematoma volumes are less likely to be spot sign positive, and therefore less likely to expand. Aim We sought to validate our prior finding that small hematomas are unlikely to expand, and to determine the relationship between baseline hematoma volume, spot sign status, and risk of hematoma expansion. Methods Data were from the prospective PREDICT ICH study. Patients presenting within 6 h of symptom onset with completed baseline CT, CTA, and follow-up CT were included. Baseline hematoma volume was categorized a priori (<3 mL, 3–10 mL, 10–20 mL, >20 mL). The primary outcome was significant hematoma expansion (≥6 mL, ≥12.5 mL or ≥33%) and secondary outcomes were early neurological worsening, good clinical outcome (modified Rankin Scale 0–3), and mortality at 90 days. Results Among 315 patients meeting the inclusion criteria, baseline hematoma volume category predicted absolute hematoma expansion ( p < 0.001), spot sign prevalence ( p < 0.001), early neurologic worsening ( p = 0.002), clinical outcome ( p < 0.001), and mortality ( p < 0.001). Very small hematomas (<3 mL) were unlikely to be spot positive (7.7%), unlikely to expand (2.6%), and were associated with a 73% chance of good clinical outcome. Spot sign appeared to be most predictive of expansion in the 3–10 mL baseline hematoma volume category. Conclusion Very small hematomas are unlikely to expand and have a low spot sign prevalence. Hemostatic therapy trials may be best targeted at hemorrhages >3 mL in volume.

Background Infarct growth (IG) is used as surrogate end-point in therapeutic trials. For practical reasons, infarct growth is commonly assessed using simple subtraction of acute from follow-up diffusion-weighted imaging (DWI) lesion volumes. However, the volume subtraction method will underestimate true infarct growth in case of diffusion-weighted imaging lesion reversal. Aim To measure the size of the difference between true infarct growth on voxel-based coregistration and infarct growth approximated with simple volume subtraction. Methods We retrospectively analyzed 322 consecutive stroke patients (median (IQR) age: 70 years (57–80), National Institute of Health Stroke Score at admission 14 (8–19)), who underwent a magnetic resonance imaging before (DWI1) and ≈24 h (DWI2) after IV-thrombolysis. IGvoxel-based was defined as the volume of signal changes on DWI2 that did not overlap with that on coregistered DWI1. This was compared with simply subtracting DWI1 from DWI2 lesion volume (IGsubtracted). We also compared these two metrics for the prediction of three-month unfavorable outcome (mRS ≥ 2) using c-statistics of multivariable models, adjusted for age, and National Institute of Health Stroke Score. Results Infarct growth volume metrics were strongly correlated (ρ = 0.94), but IGsubtracted substantially underestimated IGvoxel-based (median (IQR): 9.52 (0.23–38.9) vs. 16.98 (4.4–45.4) mL). Of the 75 patients with shrinking or stable diffusion-weighted imaging lesion using volume subtraction, IGvoxel-based was ≥5 mL in 20 (27% of the subset, 6.2% of the whole population). Moreover, IGvoxel-based better predicted unfavorable outcome than IGsubtracted (c-statistics = 0.86 (95% CI, 0.82–0.90) vs. 0.82 (0.78–0.87), P = 0.003). Conclusion At early post-thrombolysis time points, the simple subtraction of lesion volumes masked substantial diffusion-weighted imaging lesion growth in 6.2% of patients. Although more time-consuming, the voxel-based method may impact results of trials that use infarct growth attenuation as an end-point.

Published: January 2016

Background In contemporary studies, cerebral venous thrombosis is three times more common in adult women than in men. Aim To study the change in sex ratio over time in cerebral venous thrombosis. Summary of review We systematically reviewed the literature. Any type of study with at least 40 patients with cerebral venous thrombosis that reported sex ratio was eligible. We ranked studies according to the year halfway the period of patient recruitment. Pediatric studies were analyzed separately. Out of 6068 publications identified by our search, 112 studies (23,638 patients), published between 1966 and 2014, were included. The proportion of women among patients with cerebral venous thrombosis significantly increased over time from a median of 54.8% in studies prior to 1981 to 69.8% after 2001 ( p = 0.002). There was a significant correlation between time of the study and proportion of women (Pearson’s correlation coefficient 0.25, p = 0.01). Oral contraceptive use among women with cerebral venous thrombosis also increased over time (Pearson’s correlation coefficient 0.29, p = 0.01). In contrast, the percentage of pregnancy-related cases remained stable (Pearson’s correlation coefficient 0.04, p = 0.77). Among 1702 patients from pediatric studies, 39% were female and there was no correlation between sex ratio and time of the study (Pearson’s correlation coefficient −0.42, p = 0.14). Conclusions In adult patients with cerebral venous thrombosis, there is a shift in sex ratio over time with an increase in the proportion of women, whereas this is not observed in pediatric populations. A possible explanation for this phenomenon is an increase over time in the use of oral contraceptives by adult women.
The correlation of initial radiographic characteristics of distal radius fractures and injuries of the triangular fibrocartilage complex
Authors: Kasapinova K. , Kamiloski V. 
Published: January 2016

Our purpose was to determine the correlation of initial radiographic parameters of a distal radius fracture with an injury of the triangular fibrocartilage complex. In a prospective study, 85 patients with surgically treated distal radius fractures were included. Wrist arthroscopy was used to identify and classify triangular fibrocartilage complex lesions. The initial radial length and angulation, dorsal angulation, ulnar variance and distal radioulnar distance were measured. Wrist arthroscopy identified a triangular fibrocartilage complex lesion in 45 patients. Statistical analysis did not identify a correlation with any single radiographic parameter of the distal radius fractures with the associated triangular fibrocartilage complex injuries. The initial radiograph of a distal radius fracture does not predict a triangular fibrocartilage complex injury. Level of evidence: III
Do Orthogeriatric Inpatients Have a Correct Medication List? A Pharmacist-Led Assessment of 254 Patients in a Swedish University Hospital

Published: January 2016

Introduction: Comorbidities and polypharmacy complicate the treatment of geriatric patients with acute orthopedic injuries. A correct medication history and an updated medication list are a prerequisite for safe treatment of these debilitated patients. Published evidence suggests favorable outcomes with comanaged care. The aim of this study was to assess the accuracy of the inpatient medication lists generated at admission and investigate the efficacy of a dedicated ward-based pharmacist to find and correct mistakes in these lists. Methods: A total of 254 patients were enrolled. The ward-based pharmacist performed the assessment regarding the accuracy of the medication list generated at admission by the method of medication reconciliation. Number of discrepancies and types of discrepancy were noted. Results: The 254 patients (176 women) had a mean age of 85 years (standard deviation 7.4 years, range 42-100 years). The most common reason for orthopedic admission was hip fracture. The mean number of discrepancies was 2.1 for all patients (range 0-13). Omission of a prescribed drug was the most common mistake. Fifty-six (22%) of the 254 assessed patients had a correct medication list. Discussion: The many discrepancies in our study may have several explanations but highlight the difficulties in taking a correct medication history of patients in a stressful environment with an extremely high workload. Moreover, electronic medication lists create challenges. Implementing new electronic tools for health care requires feedback, redesign, and adaptation to meet various needs of the users. Conclusion: In conclusion, orthogeriatric patients have an unsatisfactory high number of discrepancies in their medication lists. Clinical pharmacists can accurately identify many of these mistakes.
Role of Emotional Intelligence in Leaders on the Commitment Level of Employees: A Study in Information Technology and Manufacturing Sector in India
Authors: Bhalerao Hemangi , Kumar Satishchandra 
Published: January 2016

The scope of this study is to explore the role of emotional intelligence (EI) in leaders on the commitment level of the subordinates. Data was collected from dyadic sources using survey method and convenient sampling. Total 155 professionals forming 89 pairs from information technology (IT) and manufacturing sector in India participated in this study. The results indicate a significant relationship between trait-based EI and affective commitment, when the designations of the leader and the subordinates were controlled. However, no significant results were found between EI and normative and continuance commitments. The result challenges some of the basic assumptions about EI and suggests that the relationship between EI and organizational commitment is complex.

Published: January 2016

AbstractElectron holography is employed to study variations of the electrostatic crystal potential in Cu(In,Ga)Se2 (CIGS) thin-film solar cells at different length scales: Long-range potential variations across the layer structure of the solar cell as well as inhomogeneities within the layers are analyzed by off-axis holography. In-line holography is applied to examine the local potential variation across a CIGS grain boundary. The phase reconstruction from a focal series is performed by a modified
transport of intensity equation (TIE) which is optimized to reduce common artifacts. For comparison, three different microscopes of different optical configurations were used for in-line holography. Based on the results, the impact of the used microscope as well as further acquisition parameters on the in-line holography measurement is assessed. The measured potential variations are discussed considering the effect of different possible sources that may cause potential fluctuations. It is found that most of the variations are best explained by mean inner potential fluctuations rather than by inhomogeneities of the electronic properties. Finally, the present resolution limit of both methods is discussed regarding the feasibility of future electronic characterization of CIGS by holography.

Published: January 2016

Este estudo aborda a gestão por competências como um serviço prestado por consultorias de recursos humanos da Grande Florianópolis, tema que está presente na pauta de discussão de assuntos gerenciais contemporâneos. Este novo formato de gestão surgiu em decorrência das exigências de crescimento, competitividade e qualidade dos mercados globalizados. Acredita-se que estudar as formas pelas quais a gestão por competências vem se tornando parte das empresas atualmente traz uma visão de como a relação colaborador-empresa é dependente entre si. Para tanto se empreendeu o presente estudo com o objetivo de analisar o processo de implantação da gestão por competências por empresas de consultoria em recursos humanos da Grande Florianópolis/SC. Metodologicamente trata-se de uma pesquisa exploratória descritiva com abordagem qualitativa, tendo a entrevista semi-estruturada como instrumento de coleta de dados. Os dados foram agrupados em quatro grandes blocos de estudo: a gestão por competências nos projetos desenvolvidos pela consultoria; motivos que levam as organizações a buscarem a gestão por competências; aspectos facilitadores e dificultadores da implantação da gestão por competências e perfil dos gestores antes e após a implantação da gestão por competências. Verificou-se que a adoção da gestão por competências parte muito mais de um esforço das próprias consultorias em implantar este serviço junto às empresas clientes do que propriamente do conhecimento e solicitação deste tipo de serviço por parte dos gestores. Palavras-chave: Gestão por competência. Consultoria. Recursos Humanos.

Published: January 2016

ObjectivesThe purpose of this study was to compare the results and complications of tibial lengthening over an intramedullary nail with treatment using the traditional Ilizarov method.MethodsIn this matched case study, 16 adult patients underwent 19 tibial lengthening over nails (LON) procedures. For the matched case group, 17 patients who underwent 19 Ilizarov tibial lengthenings were retrospectively matched to the LON group.ResultsThe mean external fixation time for the LON group was 2.6 months and for the matched case group was 7.6 months. The mean lengthening amounts for the LON and the matched case groups were 5.2 cm and 4.9 cm, respectively. The radiographic consolidation time in the LON group was 6.6 months and in the matched case group 7.6 months. Using a clinical and radiographic outcome score that was designed for this study, the outcome was determined to be excellent in 17 and good in two patients for the LON group. The outcome was excellent in 14 and good in five patients in the matched case group. The LON group had increased blood loss and increased cost. The LON group had four deep infections; the matched case group did not have any deep infections.ConclusionsThe outcomes in the LON group were comparable with the outcomes in the matched case group. The LON group had a shorter external fixation time but experienced increased blood loss, increased cost, and four cases of deep infection. The advantage of reducing external fixation treatment time may outweigh these disadvantages in patients who have a healthy soft-tissue envelope. Cite this article: J. E. Herzenberg.

Transcending noir – Claire Grove’s BBC radio adaptations of Raymond Chandler
Authors: Raw Laurence 
Published: January 2016

Abstract
By considering two of Radio 4’s most recent adaptations (2011), this article analyses how director Claire Grove recreates the noir aesthetic characteristic of post-1945 radio and film adaptations of Chandler’s work. She achieves her task through various means – subverting Marlowe’s role as the omniscient narrator, challenging our understanding of him as a hard-boiled hero, and creating deliberately discordant soundscapes denoting the corruption pervading Marlowe’s world. The experience of listening to Grove’s adaptations not only reminds us of the importance of noir in the past but also comments on corruption in the present day. Nonetheless this is not the end of the story, as Grove asks us to reflect on Marlowe’s behaviour and consider whether there are other alternatives to viewing the world through perpetually cynical spectacles.

Binary opposites – can South African journalists be both watchdogs and developmental journalists?
Authors: De Beer Arnold S. , Malila Vanessa , Beckett Sean , Wasserman Herman 
Published: January 2016

Abstract
This article challenges the traditional role ascribed by liberal and developmental media theory that journalists should either be watchdogs or developmental journalists but not both at the same time. As part of the South African leg of the Worlds of Journalism (WJS) project this article argues that it is indeed possible that the media can fulfil both roles. Utilizing the WJS 2014 questionnaire and based on a provincial face-to-face (n=37) and a national electronic survey (n=371) the results from the WJS South African project show a potential new trend in the way South African journalists see their role. This article reports in the main on the background to the face-to-face survey, while utilizing data from the national survey reported on elsewhere. Data analysis showed when both roles were compared to one another it was apparent that the watchdog and developmental roles were statistically significantly related to one another.
Thresholds, musics and liminality: professional Rom musicians and their liminal roles in nuptial rites of Bergama region<p>Eşikler, müzikler ve liminalite: profesyonel Roman müzisyenler ve Bergama yöresi evlilik ritüellerindeki liminal rolleri

Published: January 2016

<p>Three days lasting nuptial rites as examples of <em>rites of passage</em> take on a new significance with the contributions of professional musicians in Bergama’s surrounding country-side like elsewhere in Turkey. These musicians living in Bergama are often ‘Roma’. Leading the profession of musicianship up until today, these local musicians provide basically two different kinds of musical service: to encode certain stages with certain tunes over the course of the ritual and to guide the transition. As a female-centered activity, the core of the marriage ritual is a process of <em>liminality</em> in which the bride enters a new phase in her life by the help of the other women around (aunts, musicians, etc.). Unlike the relationship between the male musicians and the groom, female Rom musicians locally named ‘dümbekçiler’ stand by the bride in almost all stages of this transition and guide her to cross the inner tresholds of the ritual properly. This article aims to contribute to the understanding of the ‘liminal’ roles of the male and female Rom musicians in their company consequently to the bride, the groom and all the other members of communitas during the ritual process.</p><p> </p><p><strong>Özet</strong></p><p>Geçiş ritüellerinin (<em>rites of passage</em>) üç güne yayılan bir örneği olan evlilik ritüelleri, bugün Türkiye’nin pek çok yerinde olduğu gibi Bergama kırsalında da profesyonel müzisyenlerin katkılarıyla anlam kazanır. Bergama özelinde bu müzisyenler, büyük çoğunlukla bölgede yaşayan ‘Roman’lardır. Müzisyenlik mesleğini geçmişten günümüze profesyonel olarak sürdüren bu yerel müzisyenler, ritüel kapsamında temelde iki farklı müzik hizmeti sunarlar: Ritüel akışı boyunca belirli aşamaları belirli havalarla kodlamak ve geçişe rehberlik etmek. Kadın merkezli bir etkinlik olan evlilik ritüeli özünde gelinin; çevresindeki diğer kadınların (yengeler, müzisyenler vb.) yardımıyla yaşamının yeni bir evresine adım atmaya hazırlandığı bir eşiksellik <em>(liminality)</em> sürecidir. Yörede ‘dümbekçiler’ olarak adlandırılan Roman kadın müzisyenler bu süreçte, erkek müzisyenlerin damatla kurduğu ilişkiden farklı olarak hemen her aşamada gelinin yanında bulunarak ritüel içi eşikleri uygun bir biçimde geçmede ona rehberlik de ederler. Bu makale erkek ve kadın Roman müzisyenlerin ritüel süreci boyunca, başta gelin olmak üzere damada ve diğer tüm komünitas üyelerine eşlik ederken sergiledikleri ‘liminal’ rollerin anlaşılmasına katkı sunmayı amaçlar.</p>

Published: January 2016

AbstractThe subterranean cavities are seriously threatened to construction and mining safety, and it’s important to obtain the exact localization and dimensions of subterranean cavities for the planning of geotechnical and mining activities. Geophysical investigation is an alternative method for cavity detection, but it usually failed for the uncertainly solution of information and data obtained by Geophysical methods. Drilling is considered as the most accurate method for cavity detection. However, the conventional drilling methods can only be used for single cavity detection, and there is no effective solution for multilayer cavities detection have been reported. In this paper, a reverse circulation (RC) down-the-hole (DTH) air hammer system with a special structured drill bit is built and a cavity auto scanning laser system based on laser range finding technique was employed to confirm the localization and dimensions of the cavities. This RC-DTH air hammer system allows drilling through the upper cavities and putting the cavity auto scanning laser system into the cavity area through the central passage of the drill tools to protect the detection system from collapsing of borehole wall. The RC-DTH air hammer system was built, and field tests were conducted in Lanxian County Iron Ore District, which is located in Lv Liang city of Shan Xi province, the northwest of china. Field tests show that employing the RC-DTH air hammer system assisted by the cavity auto scanning laser system is an efficiency method to detect multilayer cavities.
