Non-stimulant treatment for Attention-Deficit/Hyperactivity Disorder
Authors: Spencer T. , Biederman J. 
Published: July 2017

A variety of compounds with a common noradrenergic/dopaminergic activity have shown documented anti-Attention-Deficit/Hyperactivity Disorder (ADHD) activity. There is a substantial body of literature documenting the efficacy of tricyclic antidepressants on ADHD in over 1,000 subjects. There is an equally large database on the efficacy of the specific norepinephrine reuptake inhibitor, atomoxetine, of greater than 2,000 individuals. In addition, the atypical antidepressant bupropion also has been documented to be effective in the treatment of ADHD in controlled clinical trials. Despite wide use, the scientific base supporting the efficacy of alpha-2, noradrenergic agonists is somewhat limited. Several lines of evidence provide preliminary support for the potential benefits of cholinergic cognitive enhancing drugs, such as anticholinesterase inhibitors (tacrine, donepezil) as well as novel nicotinic analogues (ABT-418). Despite these promising results, more research is needed on alternative pharmacological treatments for the treatment of ADHD.
Psychiatric disorders and suicide attempts among adolescents victimized by school bullying
Authors: Bang Young Rong , Park Jae Hong 
Published: July 2017

Objective: We conducted a cross-sectional school-based study to investigate psychiatric disorders and suicide risk among adolescents victimized by bullying. Method: The study was designed in two stages. In the screening stage, 33,038 middle school students were screened for psychopathology. Next, in the face-to-face interview stage, 1196 participants were assessed for psychiatric disorders using a structured diagnostic instrument. We also collected information about the participants’ experiences of bullying and history of suicidal ideation/attempts. Results: The results indicate that adolescents with a history of bullying victimization were more likely to be diagnosed with depression and psychosis than those without such a history. Multivariate logistic regression models revealed that bullying victimization was significantly associated with suicide attempts even after adjusting for demographic characteristics, depression and psychosis. Conclusions: Bullying victimization is a risk factor for depression, psychosis, and suicide ideation and attempts. The findings warrant an early intervention and suicide prevention program for victimized students and anti-bullying policies in schools.

Authors: Leung Leanne , de Lemos Mário L , Kovacic Laurel 
Published: July 2017

Background With the rising cost of new oncology treatments, it is no longer sustainable to base initial drug funding decisions primarily on prospective clinical trials as their performance in real-life populations are often difficult to determine. In British Columbia, an approach in evidence building is to retrospectively analyse patient outcomes using observational research on an ad hoc basis. Methods The deliberative framework was constructed in three stages: framework design, framework validation and treatment programme characterization, and key informant interview. Framework design was informed through a literature review and analyses of provincial and national decision-making processes. Treatment programmes funded between 2010 and 2013 were used for framework validation. A selection concordance rate of 80% amongst three reviewers was considered to be a validation of the framework. Key informant interviews were conducted to determine the utility of this deliberative framework. Results A multi-domain deliberative framework with 15 assessment parameters was developed. A selection concordance rate of 84.2% was achieved for content validation of the framework. Nine treatment programmes from five different tumour groups were selected for retrospective outcomes analysis. Five contributory factors to funding uncertainties were identified. Key informants agreed that the framework is a comprehensive tool that targets the key areas involved in the funding decision-making process. Conclusions The oncology-based deliberative framework can be routinely used to assess treatment programmes from the major tumour sites for retrospective outcomes analysis. Key informants indicate this is a value-added tool and will provide insight to the current prospective funding model.

Authors: Berkelmans Gijs FN , Visseren Frank LJ , Jaspers Nicole EM , Spiering Wilko , van der Graaf Yolanda , Dorresteijn Jannick AN 
Published: July 2017

Abstract

Background
The SPRINT trial showed a beneficial effect of systolic blood pressure treatment targets of 120 mmHg on cardiovascular risk compared to targets of 140 mmHg. However, differences in medication use, most importantly diuretics, are suggested as an alternative explanation. This post-hoc analysis aimed to determine whether the reduced event rate can be attributed to changes in systolic blood pressure (ΔSBP).

Methods
Analyses were based on all 9361 participants of the SPRINT trial. ΔSBP was defined as the change between baseline and 6-month follow-up systolic blood pressure. Major cardiovascular events were myocardial infarction, other acute coronary syndromes, stroke, heart failure, or cardiovascular death. Cox regression was used to describe the relation between ΔSBP and major cardiovascular events. Analyses were performed separately for patients in the lowest tertile of baseline systolic blood pressure, as the SPRINT trial reported the highest treatment effect in this subgroup.

Results
The relation between ΔSBP and major cardiovascular events was a hazard ratio per 10 mmHg decrease of 0.93 (95% confidence interval 0.89–0.98). Similar results were found within the lowest tertile of baseline systolic blood pressure: hazard ratio per 10 mmHg decrease 0.91 (95% confidence interval 0.82–1.01).

Conclusion
Our results show that lowering blood pressure prevents cardiovascular disease. However, not all the positive effects in the SPRINT trial could be explained by ΔSBP. Alternative explanations, such as differences in medication use, should be considered for the positive findings of the SPRINT trial.
An atypical case of trigeminal trophic syndrome: A legal medicine perspective in medical responsibility
Authors: di Luca Alessandro , Ralli Massimo , Hemied Sara , de Vincentiis Marco , di Luca Natale Mario 
Published: July 2017

Background: Trigeminal trophic syndrome is a rare complication of peripheral or central damage to the trigeminal nerve characterized by anesthesia, paresthesia and a secondary persistent facial ulceration. Methods: We describe the case of a 40-year-old woman with previous history of Le Fort I osteotomy for a class III malocclusion who developed trigeminal trophic syndrome. Atypically, the cutaneous symptoms appeared bilaterally and 8 years after surgery. Results: Differential diagnosis was based on clinical history, tissue biopsy and serologic evaluation. Atypical findings could be linked to the surgical burdens of Le Fort I osteotomy, a procedure characterized by a bilateral incision on the maxillofacial bones with a reasonable probability of causing a bilateral injury of the peripheral branches of the trigeminal nerve. Conclusion: Although the long delay between trigeminal trophic syndrome onset and surgery and the absence of adequate medical evidence cannot confirm a link with previous surgery in this case, the increasing number of maxillofacial surgery cases suggests that this complication may be more frequent in the next decades, and thus, involved specialists should be aware of this condition as a possible complication of maxillofacial surgery procedures.
Epilepsy, ataxia, sensorineural deafness, tubulopathy syndrome in a European child with KCNJ10 mutations: A case report
Authors: Papavasiliou Antigone , Foska Katerina , Ioannou John , Nagel Mato 
Published: July 2017

Background: Epilepsy, ataxia, sensorineural deafness, tubulopathy syndrome is a multi-organ disorder that links to autosomal recessive mutations in the KCNJ10 gene, which encodes for the Kir4.1 potassium channel. It is mostly described in consanguineous, non-European families. Case Report: A European male of non-consanguineous birth, with early-onset, static ataxic motor disorder, intellectual disability and epilepsy, imitating cerebral palsy, presented with additional findings of renal tubulopathy, sensorineural deafness and normal neuroimaging leading to the diagnosis of epilepsy, ataxia, sensorineural deafness, tubulopathy syndrome. The patient was heterozygous for two KCNJ10 mutations: a missense mutation (p.R65C) that is already published and a not yet published duplication (p.F119GfsX25) that creates a premature truncation of the protein. Both mutations are likely damaging. Parental testing has not been performed, and therefore, we do not know for certain whether the mutations are on different alleles. This young man presents some clinical and laboratory features that differ from previously reported patients with epilepsy, ataxia, sensorineural deafness, tubulopathy syndrome. Conclusion: The necessity of accurate diagnosis through genetic testing in patients with static motor disorders resembling cerebral palsy phenotypes, atypical clinical features and noncontributory neuroimaging is emphasized.

Published: July 2017

Background Vedolizumab is a recently available monoclonal antibody targeting α4β7 integrin for the treatment of ulcerative colitis (UC) and Crohn’s disease (CD). Objective The objective of this article is to evaluate the efficacy of vedolizumab induction therapy in anti-TNF-refractory/intolerant UC and CD patients in real life. Methods A cohort of 149 moderately to severely active UC and CD patients who failed or showed intolerance to at least two TNF antagonists participated in a medical need program and received vedolizumab in 37 Belgian centers (April–September 2015). Rates of clinical response and remission were retrospectively evaluated at Week 10 for UC and Week 14 for CD using the physician’s global assessment (PGA), Mayo score and Harvey Bradshaw index (HBI) or Crohn's disease activity score (CDAI) scores. Results Eighty-four patients (29 UC, 55 CD) had sufficient data for analysis. For UC patients, clinical response was observed in 76% based on PGA and 59% based on the Mayo score. The corresponding percentages for CD patients were 80% for PGA and 65% for HBI/CDAI. Clinical remission rates were 10% and 40% for UC and CD, respectively. Steroid-free remission was observed in respectively 10% and 35%. Globally, corticosteroids were stopped in 14 out of 48 patients (29%). No new safety signals were reported. Conclusion Up to 70% TNF-refractory/intolerant UC and CD patients achieved a clinical response after 10 to 14 weeks of vedolizumab treatment in this real-life cohort.
The relative utilities of genome-wide, gene panel, and individual gene sequencing in clinical practice

Published: July 2017

Abstract
Advances in technology that have transpired over the past 2 decades have enabled the analysis of cancer samples for genomic alterations to understand their biologic function and to translate that knowledge into clinical practice. With the power to analyze entire genomes in a clinically relevant time frame and with manageable costs comes the question of whether we ought to and when. This review focuses on the relative merits of 3 approaches to molecular diagnostics in hematologic malignancies: indication-specific single gene assays, gene panel assays that test for genes selected for their roles in cancer, and genome-wide assays that broadly analyze the tumor exomes or genomes. After addressing these in general terms, we review specific use cases in myeloid and lymphoid malignancies to highlight the utility of single gene testing and/or larger panels.

Abstract
Background
The apolipoprotein E ε4 (APOE4) genotype is a prominent late-onset Alzheimer’s disease (AD) risk factor. ApoE4 disrupts memory function in rodents and may contribute to both plaque and tangle formation.

Methods
Coimmunoprecipitation and Western blot detection were used to determine: 1) the effects of select fragments from the apoE low-density lipoprotein (LDL) binding domain and recombinant apoE subtypes on amyloid beta (Aβ)42-α7 nicotinic acetylcholine receptor (α7nAChR) interaction and tau phosphorylation in rodent brain synaptosomes; and 2) the level of Aβ42-α7nAChR complexes in matched controls and patients with mild cognitive impairment (MCI) and dementia due to AD with known APOE genotypes.

Results
In an ex vivo study using rodent synaptosomes, apoE141–148 of the apoE promotes Aβ42-α7nAChR association and Aβ42-induced α7nAChR-dependent tau phosphorylation. In a single-blind study, we examined lymphocytes isolated from control subjects, patients with MCI and dementia due to AD with known APOE genotypes, sampled at two time points (1 year apart). APOE ε4 genotype was closely correlated with heightened Aβ42-α7nAChR complex levels and with blunted exogenous Aβ42 effects in lymphocytes derived from AD and MCI due to AD cases. Similarly, plasma from APOE ε4 carriers enhanced the Aβ42-induced Aβ42-α7nAChR association in rat cortical synaptosomes. The progression of cognitive decline in APOE ε4 carriers correlated with higher levels of Aβ42-α7nAChR complexes in lymphocytes and greater enhancement by their plasma of Aβ42-induced Aβ42-α7nAChR association in rat cortical synaptosomes.

Conclusions
Our data suggest that increased lymphocyte Aβ42-α7nAChR-like complexes may indicate the presence of AD pathology especially in APOE ε4 carriers. We show that apoE, especially apoE4, promotes Aβ42-α7nAChR interaction and Aβ42-induced α7nAChR-dependent tau phosphorylation via its apoE141–148 domain. These apoE-mediated effects may contribute to the APOE ε4-driven neurodysfunction and AD pathologies.
Characterisation of preparation layers in nine Danish Golden Age canvas paintings by SEM–EDX, FTIR and GC–MS

Published: July 2017

Abstract
This study explores the materials used in the preparation layers of nine paintings from the Danish Golden Age as a first approach to understanding the variation in use of materials in the nineteenth century as well as the potential for their degradation. Paintings on canvas have traditionally been suspected to be particularly sensitive to high moisture levels because of the changing quality of materials in the nineteenth century. The explanations have partly included the mechanisation of production methods and partly a more experimental approach to painting. Additionally, collagen-based glue sizing of the canvas is suspected to respond dimensionally to changes in relative humidity. In this study, pigments, fillers and binding media in the preparation layers of nine paintings by different artists were identified using scanning electron microscopy with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and gas chromatography–mass spectrometry. The study shows a relatively low degree of variation in materials used in grounds. Surprisingly, no collagen-based binder was found in any of the nine paintings, suggesting that the canvases were not glue sized. All paintings contained calcium, lead, a drying oil and egg, even though only few contemporary recipes in painter’s manuals included egg as an ingredient for preparation layers. These results suggest that the commercial producers of prepared canvas may not have followed the manuals that were written for painters. Egg may have been added in order to increase flexibility and durability of ready primed canvases that were stored and sold in rolls. Moreover, the egg–oil emulsion has the advantage of being more viscous than a pure oil paint and could thus be used without sizing the canvas, rendering the primed canvas less stiff and less responsive to changes in relative humidity. The advantages of using egg in the ground are obvious, and this use, as well as the lack of glue size, has implications for the long-term preservation of the paintings in changing environmental conditions. These results imply that these particular paintings might be less sensitive to relative humidity changes than expected due to the lack of hygroscopic glue.

Published: July 2017

Abstract
Microbeam irradiation is spatially fractionated radiation on a micrometer scale. Microbeam irradiation with therapeutic intent has become known as microbeam radiation therapy (MRT). The basic concept of MRT was developed in the 1980s, but it has not yet been tested in any human clinical trial, even though there is now a large number of animal studies demonstrating its marked therapeutic potential with an exceptional normal tissue sparing effect. Furthermore, MRT is conceptually similar to macroscopic grid based radiation therapy which has been used in clinical practice for decades. In this review, the potential clinical applications of MRT are analysed for both malignant and non-malignant diseases.
The Influence of Hierarchy on Idea Generation and Selection in the Innovation Process
Authors: Keum Dongil D. , See Kelly E. 
Published: July 2017

The link between organizational structure and innovation has been a longstanding interest of organizational scholars, yet the exact nature of the relationship has not been clearly established. Drawing on the behavioral theory of the firm, we take a process view and examine how hierarchy of authority—a fundamental element of organizational structure reflecting degree of managerial oversight—differentially influences behavior and performance in the idea generation versus idea selection phases of the innovation process. Using a multimethod approach that includes a field study and a lab experiment, we find that hierarchy of authority is detrimental to the idea generation phase of innovation, but that hierarchy can be beneficial during the screening or selection phase of innovation. We also identify a behavioral mechanism underlying the effect of hierarchy of authority on selection performance and propose that selection is a critical organizational capability that can be strategically developed and managed through organizational design. Our investigation helps clarify the theoretical relationship between structure and innovation performance and demonstrates the behavioral and economic consequences of organizational design choice.The online appendix is available at https://doi.org/10.1287/orsc.2017.1142 .
Comparisons of external fixator combined with limited internal fixation and open reduction and internal fixation for Sanders type 2 calcaneal fractures

Published: July 2017

ObjectivesThe aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures.MethodsTwo types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.ResultsThe relative displacement of the EFLIF was less than that of the plate (0.1363 mm to 0.1808 mm). The highest von Mises stress value on the plate was 33% higher than that on the EFLIF. A normal restoration of the Böhler angle was achieved in both groups. No significant difference was found in the clinical outcome on the American Orthopedic Foot and Ankle Society Ankle Hindfoot Scale, or on the Visual Analogue Scale between the two groups (p > 0.05). Wound complications were more common in those who were treated with ORIF (p = 0.028).ConclusionsBoth EFLIF and ORIF systems were tested to 160 N without failure, showing the new construct to be mechanically safe to use. Both EFLIF and ORIF could be effective in treating Sanders type 2 calcaneal fractures. The EFLIF may be superior to ORIF in achieving biomechanical stability and less blood loss, shorter surgical time and hospital stay, and fewer wound complications. Cite this article: M. Pan, L.
