Translanguaging in L2 Arabic Study Abroad: Beyond Monolingual Practices in Institutional Talk
Authors: AL MASAEED KHALED 
Published: February 2020

AbstractAdopting a translanguaging perspective, this article examines interlocutors’ orientations to, and use of, multidialectal and multilingual practices during second language (L2) Arabic conversations‐for‐learning beyond the classroom in a study abroad program. The study argues that participants’ translanguaging practices challenge monolingual ideologies and the program's monodialectal policy of using only Modern Standard Arabic (MSA) in institutional talk beyond the classroom. Audio‐recorded dyadic interactions between L2 Arabic learners and their native speaker conversation partners show how multidialectal and multilingual practices can work as a valuable interactional resource that multilinguals draw upon for productive interactions to enhance meaning‐making, identity negotiation, and knowledge construction. In addition, participants seem to give precedence to intersubjectivity over monodialectal and monolingual language policies through their use of these translanguaging practices.

Published: February 2020

AbstractBackgroundAdolescents with chronic musculoskeletal pain face different impairments in daily life. After an inpatient pain rehabilitation program, adolescents function better on several domains. The aim of this study was to explore the long‐term work participation of adults who followed inpatient pain rehabilitation during adolescence because of chronic musculoskeletal pain and to identify potential facilitators and barriers regarding work in later life.MethodsA mixed‐methods study with standardized questionnaires and semi‐structured interviews. The questionnaires measured pain, disability, work status, and the quality and quantity of the work. The interviews contained questions about work participation. Potential participants were all patients who had participated in an inpatient pain rehabilitation program 15 to 20 years previously. Analyses were performed by thematic analysis. Using the Sherbrooke model as guidance, themes were classified into 4 systems: healthcare, workplace, legislative/insurance, and personal.ResultsFourteen patients consented to participate (12 females). Seventy‐one percent of them had paid work. The mean self‐reported quality of the work delivered was 9.6 (standard deviation = 0.5). Eighteen facilitators and 12 barriers regarding work participation later on in life were mentioned. The inpatient pain rehabilitation program was the most frequently mentioned facilitator (n = 5), while the personal system and coping‐related factors were the most frequently mentioned barriers (n = 5).ConclusionsTen out of 14 participants are currently working, most of them despite experiencing pain. Several factors based on the 4 systems of the Sherbrooke model contribute as facilitators or barriers regarding current work participation. Pain rehabilitation is mostly regarded as a facilitator for work participation later on in life.
Effects of relevance and response frequency on P3b amplitudes: Review of findings and comparison of hypotheses about the process reflected by P3b
Authors: Verleger Rolf 
Published: February 2020

AbstractDiverse psychological correlates have been ascribed to “P300,” the conspicuous P3b component of event‐related potentials (ERPs) recorded in many laboratory tasks. Traditionally, hypotheses on P3b have conceived of this component being independent from implementing the response to the present stimulus. This has changed in the recent decade when P3b has been related to aspects of the decision process. The present review first focusses on effects of the classic variables stimulus frequency and relevance on P3b amplitude. It turns out that already these effects are related to response requirements because effects of stimulus frequency actually are effects of frequency of response‐defined stimulus categories and effects of relevance may be defined as effects of graduating the response requirements. Then, constructs and hypotheses on psychological functions reflected by P3b are evaluated for their abilities in explaining those effects. The tested constructs are information, relevance, and capacity, and the hypotheses are priming, cognitive processing, memory storage, context updating, closure, response facilitation, decision, stimulus–response (S–R) link reactivation, and conscious representations. S–R link reactivation hypothesis performed best, closely followed by memory storage and closure hypotheses. To make further progress, more studies should conduct tests between competing hypotheses.
Anti‐Müllerian hormone in dogs and cats reproduction
Authors: Walter Beate 
Published: February 2020

AbstractThe anti‐Müllerian hormone (AMH) is a glycoprotein secreted by Sertoli cells in males and granulosa cells in females. It has first been determined in blood serum of dogs and cats by Place et al. in 2011 with the use of a human‐based ELISA test. Meanwhile, different immunoassays have been validated for AMH determination in animals and a variety of studies have demonstrated the clinical significance of AMH. This review summarizes the current knowledge about AMH in dogs and cats and describes future opportunities for its diagnostic use.

SummaryPhytohormonal interactions are crucial for plant development. Auxin and cytokinin (CK) both play critical roles in regulating plant growth and development; however, the interaction between these two phytohormones is complex and not fully understood. Here, we isolated a wild apple (Malus sieversii Roem) GRETCHEN HAGEN3 (GH3) gene, MsGH3.5, encoding an indole‐3‐acetic acid (IAA)‐amido synthetase. Overexpression of MsGH3.5 significantly reduced the free IAA content and increased the content of some IAA‐amino acid conjugates, and MsGH3.5‐overexpressing lines were dwarfed and produced fewer adventitious roots (ARs) than the control. This phenotype is consistent with the role of GH3 in conjugating excess free active IAA to amino acids in auxin homeostasis. Surprisingly, overexpression of MsGH3.5 significantly increased CK concentrations in the whole plant, and altered the expression of genes involved in CK biosynthesis, metabolism and signaling. Furthermore, exogenous CK application induced MsGH3.5 expression through the activity of the CK type‐B response regulator, MsRR1a, which mediates the CK primary response. MsRR1a activated MsGH3.5 expression by directly binding to its promoter, linking auxin and CK signaling. Plants overexpressing MsRR1a also displayed fewer ARs, in agreement with the regulation of MsGH3.5 expression by MsRR1a. Taken together, we reveal that MsGH3.5 affects apple growth and development by modulating auxin and CK levels and signaling pathways. These findings provide insight into the interaction between the auxin and CK pathways, and might have substantial implications for efforts to improve apple architecture.

Published: February 2020

SummaryChlorella microalgae are increasingly used for various purposes such as fatty acid production, wastewater processing, or as health‐promoting food supplements. A mass spectrometry‐based survey of N‐glycan structures of strain collection specimens and 80 commercial Chlorella products revealed a hitherto unseen intragenus diversity of N‐glycan structures. Differing numbers of methyl groups, pentoses, deoxyhexoses, and N‐acetylglucosamine culminated in c. 100 different glycan masses. Thirteen clearly discernible glycan‐type groups were identified. Unexpected features included the occurrence of arabinose, of different and rare types of monosaccharide methylation (e.g. 4‐O‐methyl‐N‐acetylglucosamine), and substitution of the second N‐acetylglucosamine. Analysis of barcode ITS1–5.8S–ITS2 rDNA sequences established a phylogenetic tree that essentially went hand in hand with the grouping obtained by glycan patterns. This brief prelude to microalgal N‐glycans revealed a fabulous wealth of undescribed structural features that finely differentiated Chlorella‐like microalgae, which are notoriously poor in morphological attributes. In light of the almost identical N‐glycan structural features that exist within vertebrates or land plants, the herein discovered diversity is astonishing and argues for a selection pressure only explicable by a fundamental functional role of these glycans.

Published: February 2020

ObjectivesIn rheumatoid arthritis (RA), fatigue is an important complaint with a significant impact on quality of life. Vitamin D has modulatory effects on cells of the immune system and may potentially affect RA disease activity and thereby RA-related fatigue. The purpose of this study was to explore associations between fatigue and vitamin D status in patients with RA.DesignHypothesis-generating cross-sectional study.SettingScheduled follow-up visits at a hospital-based general rheumatology clinic.ParticipantsPatients (n=169) with established RA.Primary outcome measures and anlysesFatigue, assessed by the Chalder fatigue questionnaire, and serum concentrations of 25-hydroxyvitamin D (25(OH)D), assessed by liquid chromatography–tandem mass spectrometry. Associations were analysed by correlation, and multivariate linear regression with adjustments for age, sex, body mass index, RA disease activity as measured by the Disease Activity Score 28-joint count C reactive protein (DAS28-CRP), psychological distress, pain and sleep. Fatigue was also compared across four groups based on the levels of serum 25(OH)D with cut points at 30, 50 and 75 nmol/L using one-way analysis of variance.ResultsTwo-thirds of the patients (116/169, 69%) were classified with low RA disease activity, that is, a DAS28-CRP score below 3.2. Their mean (SD) serum 25(OH)D concentration was 56.3 (21.2) nmol/L, with 77 (45.6%) having values below 50 nmol/L and 12 patients (7.1%) below 30 nmol/L. The correlation between fatigue and serum concentrations of 25(OH)D was weak and not statistically significant, r = −0.14 (95% CI: −0.29 to 0.03, p=0.08). In the multivariate model, fatigue was significantly associated with RA disease activity, psychological distress and pain, but not with serum 25(OH)D. Fatigue did not differ across groups with varying levels of serum 25(OH)D.ConclusionThis cross-sectional study found no evidence of association between vitamin D and fatigue in patients with RA.

ObjectivesBariatric surgery is the most clinically effective treatment for people with severe and complex obesity, however, the psychosocial outcomes are less clear. Follow-up care after bariatric surgery is known to be important, but limited guidance exists on what this should entail, particularly related to psychological and social well-being. Patients’ perspectives are valuable to inform the design of follow-up care. This study investigated patients’ experiences of life after bariatric surgery including important aspects of follow-up care, in the long term.DesignA qualitative study using semistructured individual interviews. A constant comparative approach was used to code data and identify themes and overarching concepts.SettingBariatric surgery units of two publicly funded hospitals in the South of England.ParticipantsSeventeen adults (10 women) who underwent a primary operation for obesity (mean time since surgery 3.11 years, range 4 months to 9 years), including Roux-en-Y gastric bypass, adjustable gastric band and sleeve gastrectomy, agreed to participate in the interviews.ResultsExperiences of adapting to life following surgery were characterised by the concepts of ‘normality’ and ‘ambivalence’, while experiences of ‘abandonment’ and ‘isolation’ dominated participants’ experiences of follow-up care. Patients highlighted the need for more flexible, longer-term follow-up care that addresses social and psychological difficulties postsurgery and integrates peer support.ConclusionsThis research highlights unmet patient need for more accessible and holistic follow-up care that addresses the long-term multidimensional impact of bariatric surgery. Future research should investigate effective and acceptable follow-up care packages for patients undergoing bariatric surgery.
The Lanczos potential and Chern–Simons theory
Authors: Roberts Mark D. 
Published: February 2020

In electromagnetism, the Faraday tensor [Formula: see text] can be constructed from the vector potential [Formula: see text], it is possible to add term to the Lagrangian depending on [Formula: see text] but not its derivatives called Chern–Simons terms. In gravitation, the Weyl tensor [Formula: see text] can be constructed from the Lanczos potential [Formula: see text], I pursue the analogy to see if terms of Chern–Simons form can be added to the Lagrangian. A new tensor [Formula: see text] is introduced which is constructed from the Lanczos potential and is of the same form as that of the Weyl tensor [Formula: see text] expressed in terms of the Lanczos potential except that covariant differentiation is replaced by transvection with a vector [Formula: see text]. The new tensor has associated invariants [Formula: see text] and [Formula: see text], the first of these can be interpreted as a Chern–Simons term for Weyl [Formula: see text] gravity. Both invariants allow various tensors to be constructed and some of their properties are investigated by using exact examples.

Background Phase-contrast magnetic resonance imaging (PC-MRI) can determine pulmonary hemodynamics non-invasively. Pulmonary hypertension causes changes in pulmonary hemodynamics and is a factor for acute exacerbation and death in interstitial lung diseases (ILD). Purpose To determine associations between pulmonary hemodynamics measured by PC-MRI and short-term mortality in patients with ILD. Material and Methods Pulmonary hemodynamics, measured by PC-MRI in 43 patients with ILD, were reviewed retrospectively. Evaluation parameters included heart rate, right cardiac output, average flow, average velocity, acceleration time, acceleration volume (AV), maximal change in flow rate during ejection (M), M/AV, maximum area, minimum area, and relative area change in the pulmonary artery (PA). All causes of death within one year from the day of the MRI examination were assessed by reviewing medical records. Associations between evaluation parameters and outcome were determined by univariate and multivariate Cox regression analysis. Results Six patients (13.9%) died by the one-year follow-up. Age (hazard ratio [HR] 1.116, 95% confidence interval [CI] 1.015–1.269), average flow (HR 0.932, 95% CI 0.870–0.984), average velocity (HR 0.778, 95% CI 0.573–0.976), right cardiac output (HR 0.870, 95% CI 0.758–0.967), AV (HR 0.840, 95% CI 0.669–0.985), M/AV (HR 1.008, 95% CI 1.001–1.014), and PA relative area change (HR 0.715, 95% CI 0.459–0.928) predicted death in univariate Cox analysis. Multivariate Cox analysis showed decreased right cardiac output (HR 0.547, 95% CI 0.160–0.912) and decreased PA relative area change (HR 0.538, 95% CI 0.177–0.922) were independently associated with death. Conclusion Reduction in right cardiac output and decreased PA relative area change, detected by PC-MRI, were associated with increased mortality in ILD.

Background Since ballet dancers begin their training before skeletal maturity, accurate and non-invasive identification of cartilage diseases is clinically important. Angle-dependent analysis of T1rho and T2 sequences can be useful for quantification of the composition of cartilage. Purpose To investigate the angle-dependent T1rho and T2 profiles of ankle cartilage in non-dancers and dancers. Material and Methods Ten female non-dancers, ten female dancers, and 9 male dancers were evaluated using T1rho and T2 mapping sequences. Manual segmentation of talar and tibial cartilage on these images was performed by two radiologists. Inter- and intra-rater reliabilities were calculated using intraclass correlation coefficients (ICCs) and Bland–Altman analysis. Mean thickness and volume of cartilage were estimated. Angle-dependent relaxation time profiles of talar and tibial cartilage were created. Results ICCs of the number of segmented pixels were poor to excellent. Bland–Altman plots indicated that differences were associated with segment sizes. Segmented cartilage on T1rho demonstrated larger thickness and volume than those on T2 in all populations. Male dancers showed larger cartilage thickness and volume than female dancers and non-dancers. Each cartilage demonstrated angular-dependent T1rho and T2 profiles. Minimal T1rho and T2 values were observed at approximately 180°–200°; higher values were seen at the angle closer to the magic angle. Minimal T2 value of talar cartilage of dancers was larger than that of non-dancers. Conclusion In this small cohort study, regional and sex variations of ankle cartilage T1rho and T2 values in dancers and non-dancers were demonstrated using an angle-dependent approach.
Cost–Utility Analysis of Mindfulness-Based Cognitive Therapy Versus Antidepressant Pharmacotherapy for Prevention of Depressive Relapse in a Canadian Context: Analyse coût-utilité de la thérapie cognitive basée sur la pleine conscience contre la pharmacothérapie antidépressive pour prévenir la rechute de la dépression en contexte canadien
Authors: Pahlevan Tina , Ung Christine , Segal Zindel 
Published: February 2020

Objective: Patients suffering from major depressive disorder (MDD) experience impaired functioning and reduced quality of life, including an elevated risk of episode return. MDD is associated with high societal burden due to increased healthcare utilization, productivity losses, and suicide-related costs, making the long-term management of this illness a priority. The purpose of this study is to evaluate the cost-effectiveness of mindfulness-based cognitive therapy (MBCT), a first-line preventative psychological treatment, compared to maintenance antidepressant medication (ADM), the current standard of care. Method: A cost–utility analysis was conducted over a 24-month time horizon to model differences between MBCT and ADM in cost and quality-adjusted life years (QALY). The analysis was conducted using a decision tree analytic model. Intervention efficacy, utility, and costing data estimates were derived from published sources and expert consultation. Results: MBCT was found to be cost-effective compared to maintenance ADM over a 24-month time horizon. Antidepressant pharmacotherapy resulted in 1.10 QALY and $17,255.37 per patient on average, whereas MBCT resulted in 1.18 QALY and $15,030.70 per patient on average. This resulted in a cost difference of $2,224.67 and a QALY difference of 0.08, in favor of MBCT. Multiple sensitivity analyses supported these findings. Conclusions: From both a societal and health system perspective, utilizing MBCT as a first-line relapse prevention treatment is potentially cost-effective in a Canadian setting. Future economic evaluations should consider combined treatment (e.g., ADM and psychotherapy) as a comparator and longer time horizons as the literature advances.

Published: February 2020

Background: Overall, a disproportionately small number of end-stage renal disease (ESRD) patients start peritoneal dialysis (PD) in the United States compared to hemodialysis. Little is known about whether gender has an effect on the initial modality of renal replacement therapy utilized by patients; however, prior studies have demonstrated gender disparities in the diagnosis and treatment of various other health conditions, including kidney disease. Methods: Using data from the United States Renal Data System (USRDS), we estimated the proportion of patients utilizing PD as their initial dialysis modality between 2000 and 2014, adjusting estimates to the mean value of all covariates and compared these estimates for women and men. Results: We found that 7.9% of women and 7.5% of men used PD as their initial dialysis modality. The unadjusted odds ratio (OR) of women initiating PD as their initial modality compared to men was 1.04 (95% CI 1.02–1.05, p < 0.001). After adjustment for age, race, ethnicity, cause of ESRD, number of comorbidities, income, employment status, and timing of referral to nephrology, the difference was even more significant, with women being 12% (OR 1.12, CI 1.10–1.14, p < 0.001) more likely to initiate PD than men. However, within different subgroups, older women and women with higher number of comorbidities were less likely to be on PD than their male counterparts. Conclusions: Our results indicate that gender plays a role in the initial dialysis modality used by patients and providers should be cognizant of these gender differences. Further studies are needed to ascertain the cause of this observed difference.
