Detailed analysis of spinal deformity is important within orthopaedic healthcare, in particular for assessment of idiopathic scoliosis. This paper addresses this challenge by proposing an image analysis method, capable of providing a full three-dimensional spine characterization. The proposed method is based on the registration of a highly detailed spine model to image data from computed tomography. The registration process provides an accurate segmentation of each individual vertebra and the ability to derive various measures describing the spinal deformity. The derived measures are estimated from landmarks attached to the spine model and transferred to the patient data according to the registration result. Evaluation of the method provides an average point-to-surface error of 0.9 mm ± 0.9 (comparing segmentations), and an average target registration error of 2.3 mm ± 1.7 (comparing landmarks). Comparing automatic and manual measurements of axial vertebral rotation provides a mean absolute difference of 2.5° ± 1.8, which is on a par with other computerized methods for assessing axial vertebral rotation. A significant advantage of our method, compared to other computerized methods for rotational measurements, is that it does not rely on vertebral symmetry for computing the rotational measures. The proposed method is fully automatic and computationally efficient, only requiring three to four minutes to process an entire image volume covering vertebrae L5 to T1. Given the use of landmarks, the method can be readily adapted to estimate other measures describing a spinal deformity by changing the set of employed landmarks. In addition, the method has the potential to be utilized for accurate segmentations of the vertebrae in routine computed tomography examinations, given the relatively low point-to-surface error

Anchoring Tablets in Organizational Practices - a Practice Based Approach to the Digitalization of Board Work

Drawing on new technologies, decision makers attempt to design and make real visions for the future of organizations and society. Aiming for successful enactment, instead they are often faced with resistance or unintended changes to existing practices and values. This paper addresses this challenge from a practice theory perspective. Taking our departure in the reflexive dualities of practices and constitutive rules, we present and put into action an analytical model to shed light on how IS-enabled organizational change is enabled and sustained via dynamic interplay, inherent relations and performative enactment. The empirical material consists of interviews and observations in a Swedish municipality. The contribution includes an account as to how the enactment and definition of fundamental social relations affect the introduction of digital board packs via tablets to either serve as a catalyst to establish and reproduce new setups and practices in the board room or simply fail

Light railways and busways as key driver for sustainable urban development: The Swedish experiences with transit‐oriented development (TOD)

Sustainable urbanism and good placemaking revolve around creating and maintaining sustainable and attractive places, by reviving planning and urban design paradigms, by experimenting and innovating and by building synergies between the old and the new. The expectations for wide accessibility and networking are very high and the challenge today is to integrate and improve the efficiency and effectiveness of urban and transport systems. The transports have to fulfil the ongoing demands for enhanced efficiency, comfort, safety and speed, as well as the environmental factors in the light of global climate change and energy crisis. One accent in the last 20 years has been on transit‐oriented development (TOD), compact cities and urbanity‐empowering public transports like light railways or light rail transit (LRT) or bus rapid transit (BRT) with its busways as key drivers for sustainable neighbourhoods. TOD in a Swedish (European) perspective is by no means a new idea. Three cases of newer light railway and busway projects (Stockholm, Gothenburg and Norrkoping) are explored in this article and they are seen through a historical overview of the TOD experiences in Sweden and around the world. We also investigate and draw attention to the values of placemaking and sustainable urbanism via the advantages and disadvantages of the urban and regional public transport systems and TOD principles

Incidence of Raynaud's phenomenon in relation to hand-arm vibration exposure among male workers at an engineering plant a cohort study

<p>Abstract</p> <p>Background</p> <p>The objective of this study was to assess the incidence of Raynaud's phenomenon in relation to hand-arm vibration exposure in a cohort consisting of male office and manual workers.</p> <p>Methods</p> <p>The baseline population consisted of 94 office and 147 manual workers at an engineering plant. Raynaud's phenomenon (RP) was assessed at baseline and at follow up (at 5, 10 and 15 years). A retrospective and a prospective cohort analysis of data were done. Hand-arm vibration exposure dose was defined as the product of exposure duration and the weighted hand-arm vibration exposure value according to ISO 5349-1.</p> <p>Results</p> <p>The retrospective/prospective incidence of Raynaud's phenomenon was 16/14 per 1000 exposure years among exposed and 2.4/5.0 per 1000 years among the not exposed. The retrospective dose response curve based on 4 dose classes showed that class 2, 3 and 4 had similar response and showed higher incidence than the not-exposed. The dose with RP response to hand-arm vibration corresponded to a 10 year A(8) value between 0.4–1.0 m/s².</p> <p>Conclusion</p> <p>The results indicate that the EU directive on an action value for hand-arm vibration of 2.5 m/s²is not too low. Rather, it suggests that employers should take on actions even at exposure values of 1 m/s²A(8).</p

Childhood neurodevelopmental disorders and violent criminality : a sibling control study

Introduction: The longitudinal relationship between attention deficit hyperactivity disorder (ADHD) and violent criminality has been extensively documented, while long-term effects of autism spectrum disorders (ASDs), tic disorders (TDs), and obsessive compulsive disorder (OCD) on criminality have been scarcely studied.Methods: Using population-based registers of all child and adolescent mental health services in Stockholm, we identified 3,391 children, born 1984–1994, with neurodevelopmental disorders, and compared their risk for subsequent violent criminality with matched controls. Results: Individuals with ADHD or TDs were at elevated risk of committing violent crimes, no such association could be seen for ASDs or OCD. Conclusions: ADHD and TDs are risk factors for subsequent violent criminality, while ASDs and OCD are not associated with violent criminality.VetenskapsrådetFASAccepte

Femtosecond laser-assisted cataract surgery versus standard phacoemulsification cataract surgery : study from the European Registry of Quality Outcomes for Cataract and Refractive Surgery

PURPOSE: To compare the visual, refractive, and adverse outcomes of femtosecond laser-assisted cataract surgery and conventional phacoemulsification cataract surgery. SETTING: Cataract surgery clinics in 9 European countries and Australia (femtosecond-assisted) and 18 European countries and Australia (conventional). DESIGN: Multicenter case-control study. METHODS: Eyes having femtosecond laser-assisted cataract surgery were matched to eyes from the European Registry of Quality Outcomes for Cataract and Refractive Surgery phacoemulsification cataract surgery database for preoperative corrected distance visual acuity (CDVA), age, and preoperative risk factors. Intraoperative and postoperative complications, postoperative CDVA, and refractive outcome were compared. The follow-up was 7 to 60 days. RESULTS: The study matched 2814 femtosecond-assisted cases to 4987 conventional phacoemulsification cases. Femtosecond-assisted surgery compared as follows to conventional phacoemulsification: posterior capsule complications, 0.7% versus 0.4%; postoperative logMAR CDVA, 0.05 (6/6(-3)) versus 0.03 (6/6(-2)); worse postoperative CDVA at follow-up (by 5 letters or more), 1.0% versus 0.4%; CDVA 0.3 (6/12) or better, 96.3% versus 97.1%; absolute biometry prediction error, 0.43 diopter (D) versus 0.40 D; within ±0.5 D of target, 72% versus 74.3%; and postoperative complications, 3.4% versus 2.3%. CONCLUSIONS: Femtosecond laser-assisted cataract surgery did not yield better visual or refractive outcomes than conventional phacoemulsification cataract surgery. Intraoperative complications were similar and low in both groups. Postoperative complications were lower in conventional phacoemulsification cataract surgery.
