Power estimations for non-primary outcomes in randomised clinical trials

Objective and methods: It is rare that trialists report power estimations of non-primary outcomes. In the present article, we will describe how to define a valid hierarchy of outcomes in a randomised clinical trial, to limit problems with Type I and Type II errors, using considerations on the clinical relevance of the outcomes and power estimations. Conclusion: Power estimations of non-primary outcomes may guide trialists in classifying non-primary outcomes as secondary or exploratory. The power estimations are simple and if they are used systematically, more appropriate outcome hierarchies can be defined, and trial results will become more interpretable.
A computer-based avatar task can differentiate avoidant and non-avoidant coping styles*

ABSTRACT Background/Objective: Coping styles play a role in how individuals respond to stress and therapy. One aspect of coping which has been linked to adverse outcomes including anxiety disorders and PTSD is avoidance. However, a tendency to avoid may affect the accuracy of paper and pencil inventories used to identify avoidant temperaments. Previously, we showed that a computer-based task in which an on-screen “avatar” is guided through a series of onscreen events could predict avoidance including behavioral inhibition, harm avoidance, and self-reported PTSD symptoms. Since some coping styles involve avoidance, we extended this work to determine whether scores on the avatar task would also differentiate avoidant and non-avoidant coping styles as measured by the Brief COPE. Methods: One hundred and fifty undergraduates voluntarily completed the avatar task and the Brief COPE. Results: Scores on the avatar task had a significant positive relationship with an aggregate score for the five avoidant coping styles and a significant negative relationship with an aggregate score for the nine non-avoidant coping styles. Conclusions: The effectiveness of the avatar task to differentiate coping styles based on avoidance further validates this task and also shows selectivity to avoidant coping styles as opposed to other non-avoidant coping styles.
Coarse-Grained Modelling and Temperature Effect on the Morphology of PS-b-PI Copolymer

Spontaneous spatial organization behavior and the aggregate morphology of polystyrene-block-polyisoprene (PS-b-PI) copolymer were investigated. Molecular dynamic (MD) and mesoscopic simulations using the dynamic of mean field density functional theory (DDF) were adopted to investigate the morphology changes exhibited by this block copolymer (BCP). In the mesoscopic simulations, several atoms in repeating units were grouped together into a bead representing styrene or isoprene segments as a coarse-grained model. Inter-bead interactions and essential parameters for mesoscopic models were optimized from MD simulations. Study indicated that morphology alternations can be induced in this system at annealing temperature of 393, 493, and 533 K. From our simulations, lamellar, bicontinuous, and hexagonally packed cylindrical equilibrium morphologies were achieved. Our simulated morphologies agree well with the reported experimental evidence at the selected temperature. The process of aggregate formation and morphology evolution were concretely clarified.
Structural Modeling and Policy Simulation

A primary goal of research in marketing is to evaluate and recommend optimal policies for marketing actions, or “instruments” in the terminology of Franses (2005). In this respect, marketing is a very policy-oriented field, and it is ironic that so much published research skirts the issue of policy evaluation. Franses’s article draws much needed attention to the question of what sort of model is usable for policy simulation and evaluation. Our perspective on what constitutes a valid model for policy evaluation differs from Franses’s view, but we believe our view complements his in many important respects. We also strongly believe that marketing has much to contribute to the literature on structural modeling. We outline some of what we believe are the advantages for marketing scholars of using structural modeling for policy evaluations and some of the challenges presented by marketing problems. Franses focuses on a reduced-form sales response model in which the outcome variable (yt) is modeled conditional on marketing variables (xt). If customers anticipate future marketing actions and take these into account in responding to the environment at time t, an additional equation is appended to the system to describe the evolution of the xt variables. In Franses’s view, this system can be used for policy simulation if both the y and x equations have timeinvariant parameters. That is, the Lucas critique, which implies that parameters of reduced-form models change if the policy regime changes, does not apply. According to Franses, a model must pass standard diagnostics, possess good predictive properties, and exhibit parameter stability to be useful for policy simulation. We applaud the attention Franses is bringing to model diagnostics. We believe that structural work in both marketing and economics should pay close attention to the central features of the data. Increased use of model diagnostics will help ensure that structural models are capable of capturing these features. However, we do not believe that all the criteria proposed by Franses, such as out-of-sample validity and parameter stability, are either necessary or sufficient to render a model useful for policy simulation. Reduced-form models can pass all diagnostics, including out-of-sample validation, and still provide misleading predictions about the effects of policy changes. Reduced-form
Impaired structural connectivity between dorsal attention network and pulvinar mediates the impact of premature birth on adult visual–spatial abilities

The dorsal attention network (DAN), including frontal eye fields and posterior parietal cortices, and its link with the posterior thalamus, contribute to visual–spatial abilities. Very premature birth impairs both visual–spatial abilities and cortico‐thalamic structural connectivity. We hypothesized that impaired structural DAN‐pulvinar connectivity mediates the effect of very premature birth on adult visual–spatial abilities. Seventy very premature (median age 26.6 years) and 57 mature born adults (median age 26.6 years) were assessed with cognitive tests and diffusion tensor imaging. Perceptual organization (PO) index of the Wechsler Adult Intelligence Scale‐III was used as a proxy for visual–spatial abilities, and connection probability maps in the thalamus, derived from probabilistic tractography from the DAN, were used as a proxy for DAN‐thalamic connectivity. Premature born adults showed decreases in both PO‐index and connection probability from DAN into the pulvinar, with both changes being positively correlated. Moreover, path analysis revealed that DAN‐pulvinar connectivity mediates the relationship between very premature birth and PO‐index. Results provide evidence for long‐term effects of very premature birth on structural DAN‐pulvinar connectivity, mediating the effect of prematurity on adult visual–spatial impairments. Data suggest DAN‐pulvinar connectivity as a specific target of prognostic and diagnostic procedures for visual–spatial abilities after premature birth.
Empathy and Attending to Patient Religion/Spirituality: Findings from a National Survey of Muslim Physicians

Attending to patient religion and spirituality (R/S) generates controversy. Some worry that because physicians lack formal religious training they may overstep their expertise, while others argue that physicians who are attentive to patient R/S provide higher quality of care. We aimed to describe American Muslim physicians’ perspectives and practices regarding R/S discussions, and how physician characteristics correlate with these. A questionnaire including measures of religiosity, empathy, and attitudes and behaviors toward R/S, was randomly administered to Islamic Medical Association of North America members. More empathetic physicians were more likely to inquire about patients’ R/S, share their own religious ideas and experiences, and encourage patients in their own R/S beliefs and practices (β = .44, p < .01). More empathetic physicians also had greater odds of encouraging discontinuation of futile life-sustaining interventions (OR 1.90, p < .05). Additionally, respondents with higher empathy had greater odds of encouraging patients at the end-of-life to seek reconciliation with God (OR 3.27, p < .001), and seek the forgiveness of those they have wronged (OR 2.48, p < .001). In the context of R/S diversity among the patient and provider population, enhancing physician empathy may be key to attending to the health-related R/S needs of patients.
Hemoglobin A1c Levels During Pregnancy and Risk of Autism Spectrum Disorders in Offspring.

Hemoglobin A1c Levels During Pregnancy and Risk of Autism Spectrum Disorders in Offspring Maternal preexisting type 1, type 2, or gestational diabetes diagnosed relatively early in pregnancy are associated with increased risk for autism spectrum disorders (ASDs) in offspring.1,2 This study extends previous observations by examining the association between maternal hemoglobin A1c (HbA1c) levels during pregnancy and risk of ASD in offspring.
Cyclic hydrostatic compress force regulates apoptosis of meniscus fibrochondrocytes via integrin alpha5beta1.

Meniscus is a semilunar fibrocartilaginous tissue, serving important roles in load buffering, stability, lubrication, proprioception, and nutrition of the knee joint. The degeneration and damage of meniscus has been proved to be a risk factor of knee osteoarthritis. Mechanical stimulus is a critical factor of the development, maintenance and repair of the meniscus fibrochondrocytes. However, the mechanism of the mechano-transduction process remains elusive. Here we reported that cyclic hydrostatic compress force (CHCF) treatment promotes proliferation and inhibits apoptosis of the isolated primary meniscus fibrochondrocytes (PMFs), via upregulating the expression level of integrin alpha5beta1. Consequently, increased phosphorylated-ERK1/2 and phosphorylated-PI3K, and decreased caspase-3 were detected. These effects of CHCF treatment can be abolished by integrin alpha5beta1 inhibitor or specific siRNA transfection. These data indicate that CHCF regulates apoptosis of PMFs via integrin alpha5beta1-FAK-PI3K/ERK pathway, which may be an important candidate approach during meniscus degeneration.
Evaluation of the GPS Precise Orbit and Clock Corrections from MADOCA Real-Time Products

The Japanese Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system covering the entire Asia-Oceania region. Except for the standard satellite navigation signals, QZSS satellites also broadcast L6E augmentation signals with real time GNSS precise orbit every 30 s and clock messages every 1 s, which is very important and necessary for Real-Time precise point positioning (RTPPP) applications. In this paper, the MADOCA real-time services derived from L6E augmentation signals were evaluated for both accuracy and availability compared with IGS final products. To avoid the datum difference of GPS orbit between MADOCA real-time and IGS final products, the 7-parameters Helmert transformation was firstly used in this paper, and then the orbit was evaluated on radial, along, and cross-track directions. On the clock evaluation, the mean satellites clock errors were taken as reference clock error, and then the standard deviation (STD) was calculated for each satellite. Furthermore, the signal in space range errors (SISRE) were also summarized to evaluate the ranging-measurement accuracy. Seven-day evaluation results show that satellite orbit, clock errors, and the final SISRE errors range as being 1.8–3.9 cm, 0.04–0.15 ns (1.2–4.5 cm), and 5–10 cm, respectively. For the one-year long-term evaluation, daily SISRE errors in 2018 show consistent performance with that of seven days. Furthermore, the open source software RTKLIB was used to evaluate the kinematic PPP performance based on the MADOCA real-time products, and it shows that the daily positioning accuracy of the 20 globally distributed IGS stations can reach 4.9, 4.2, 11.7, and 12.1 cm in the east, north, up, and 3D directions, respectively. Hence, it is concluded that the current MADOCA real-time ephemeris products can provide orbit and clock products with SISRE on centimeters level with high interval, which could meet the demands of the RTPPP solution and serve real-time users who can access the MADOCA real-time products via L6E signal or internet.
Repositioning Glucagon Action in the Physiology and Pharmacology of Diabetes

Glucagon is historically described as the counterregulatory hormone to insulin, induced by fasting/hypoglycemia to raise blood glucose through action mediated in the liver. However, it is becoming clear that the biology of glucagon is much more complex and extends beyond hepatic actions to exert control on glucose metabolism. We discuss the inconsistencies with the canonical view that glucagon is primarily a hyperglycemic agent driven by fasting/hypoglycemia and highlight the recent advances that have reshaped the metabolic role of glucagon. These concepts are placed within the context of both normal physiology and the pathophysiology of disease and then extended to discuss emerging strategies that incorporate glucagon agonism in the pharmacology of treating diabetes.
Egg Consumption and Risk of Total and Cause-Specific Mortality: An Individual-Based Cohort Study and Pooling Prospective Studies on Behalf of the Lipid and Blood Pressure Meta-analysis Collaboration (LBPMC) Group

Abstract The associations of egg consumption with total, coronary heart disease (CHD), and stroke mortality are poorly understood. We prospectively evaluated the link between total, CHD, and stroke mortality with egg consumption using a randomly selected sample of U.S. adults. Next we validated these results within a meta-analysis and systematic review of all available prospective results. We assessed the mean of cardiometabolic risk factors across the intake of eggs. We made the analysis based on data from the National Health and Nutrition Examination Surveys (NHANES; 1999–2010). In NHANES, vital status through December 31, 2011, was ascertained. Cox proportional hazard regression models were used to relate baseline egg consumption with all-cause and cause-specific mortality. PubMed, Scopus, Web of Science, and Google Scholar databases were also searched (up to December 2017). The DerSimonian-Laird method and generic inverse variance methods were used for quantitative data synthesis. Overall, 23,524 participants from NHANES were included (mean age of 47.7 years; 48.7% were men). Across increasing the intake of eggs, adjusted mean levels of cardiometabolic risk factors worsened. Adjusted logistic regression showed that participants in the highest category of egg intake had a greater risk of diabetes (T2DM; 30%) and hypertension (HTN; 48%). With regard to total and CHD mortality, multivariable Cox regression in a fully adjusted model showed no link in males and females. In males, egg intake had a reverse (66%) association with stroke mortality, while this link was not significant among females. The results of pooling data from published prospective studies also showed no link between CHD and total mortality with egg consumption, whereas we observed a reverse (28%) association between egg intake and stroke mortality. These findings were robust after sensitivity analysis. According to our findings, egg intake had no association with CHD and total mortality, whereas was associated with lower risk of mortality from stroke. Egg consumption was associated with T2DM, HTN, C-reactive protein, and markers of glucose/insulin homeostasis. If confirmed in clinical trials (causation), this information may have applications for population-wide health measures. Key teaching points No link between total and CHD mortality with eggs intake in males and females. In males, egg intake had a reverse association with stroke mortality, while this link was not significant among females. The results of pooling data from published prospective studies also showed no link between CHD and total mortality with egg consumption, whereas we observed a reverse association between egg intake and stroke mortality.
Colonic mucosal and exfoliome transcriptomic profiling and fecal microbiome response to a flaxseed lignan extract intervention in humans.

BACKGROUND Microbial metabolism of lignans from high-fiber plant foods produces bioactive enterolignans, such as enterolactone (ENL) and enterodiol (END). Enterolignan exposure influences cellular pathways important to cancer risk and is associated with reduced colon tumorigenesis in animal models and lower colorectal cancer risk in humans. OBJECTIVES The aim of this study was to test the effects of a flaxseed lignan supplement (50 mg secoisolariciresinol diglucoside/d) compared with placebo on host gene expression in colon biopsies and exfoliated colonocyte RNA in feces and fecal microbial community composition, and to compare responses in relation to ENL excretion. METHODS We conducted a 2-period randomized, crossover intervention in 42 healthy men and women (20-45 y). We used RNA-seq to measure differentially expressed (DE) genes in colonic mucosa and fecal exfoliated cells through the use of edgeR and functional analysis with Ingenuity Pathway Analysis. We used 16S ribosomal RNA gene (V1-V3) analysis to characterize the fecal microbiome, and measured END and ENL in 24-h urine samples by gas chromatography-mass spectrometry. RESULTS We detected 32 DE genes (false discovery rate <0.05) in the exfoliome, but none in the mucosal biopsies, in response to 60 d of lignan supplement compared with placebo. Statistically significant associations were detected between ENL excretion and fecal microbiome measured at baseline and at the end of the intervention periods. Further, we detected DE genes in colonic mucosa and exfoliome between low- and high-ENL excreters. Analysis of biopsy samples indicated that several anti-inflammatory upstream regulators, including transforming growth factor β and interleukin 10 receptor, were suppressed in low-ENL excreters. Complementary analyses in exfoliated cells also suggested that low-ENL excreters may be predisposed to proinflammatory cellular events due to upregulation of nuclear transcription factor κB and NOS2, and an inhibition of the peroxisome proliferator-activated receptor γ network. CONCLUSIONS These results suggest that ENL or other activities of the associated gut microbial consortia may modulate response to a dietary lignan intervention. This has important implications for dietary recommendations and chemoprevention strategies. This study was registered at clinicaltrials.gov as NCT01619020.
Effect of dimethylacetamide and N-methylacetamide on the quality and fertility of frozen/thawed chicken semen.

The aim was to compare the effect of dimethylacetamide (DMA) and N-methylacetamide (NMA) concentrations on the quality and fertility of post-thaw chicken semen. Ejaculates were obtained from 30 Hi-Line White roosters and processed according to the following treatments: lake pre-freezing extender + 0.1 M trehalose (LPF-T) + 6% DMA (control treatment), LPF-T + 9% DMA, LPF-T + 6% NMA, and LPF-T + 9% NMA. Sperm quality (viability, motility, and kinetic traits) was assessed before and after cryopreservation. A total of 15 laying hens per treatment were inseminated to assess fertility and embryo viability. Sperm cryopreserved in presence of DMA had significantly better in vitro quality compared to NMA, showing the highest proportion of viable and progressive motile sperm recovered after thawing. Furthermore, proportion of progressive motile sperm and the VCL, LIN, ALH, and WOB mean values were significantly improved in semen samples frozen/thawed with 6% compared to 9% cryoprotectant concentration. However, the best cryoprotective action on sperm quality played by DMA and the lowest cryoprotectant concentration did not translate into a concomitant advantage in in vivo semen fertility that showed no differences between cryoprotectant and cryoprotectant concentration treatments. Finally, the cryoprotectant DMA and NMA showed an opposite effect on embryo viability in comparison with the effect played on in vitro semen quality, being NMA more efficient than DMA on preserving viable embryos. The present results suggest the urgency to further decrease the cryoprotectant concentration in poultry semen freezing procedures and to assess the specific toxic effect of cryoprotectant on sperm integrity, fertility, and embryo development.
Youth living with HIV/AIDS in secondary schools: perspectives of peer educators and patron teachers in Western Uganda on stressors and supports

ABSTRACT As Youth Living With HIV/AIDS (YLWHA) continue to survive and live with HIV chronically due to effective Antiretroviral Therapy (ART), it is paramount to work toward maximising their psychosocial wellbeing. The school where these YLWHA are expected to spend most of their time is an excellent environment to investigate this. In this study, we explore perspectives of Peer Educators (PEs) in secondary schools of one district in Western Uganda on how YLWHA are perceived in school, on their daily stressors and their way of coping with their HIV-positive serostatus given the support of the schools. We conducted eight focus groups with a total of 59 students who were members of Peer Educators Clubs (PECs) as well as 8 in-depth interviews with patron teachers of PECs in eight secondary schools of Kabarole district, selected through a stratified random sampling method. Focus groups and interviews were tape-recorded, transcribed and analysed thematically both inductively and deductively. Stressors and support in schools, as identified by the PEs were categorised into three interrelated thematic domains; psychological wellbeing of YLWHA, disclosure of HIV status by YLWHA, and health and treatment adherence. Stigma was found to be a key stressor and an intermediary in all the three thematic domains Stressors affecting psychological wellbeing were fear of death and uncertainty of the future compounded by financial and academic challenges. Stressors affecting disclosure centred around lack of privacy, confidentiality and fear of loss of friends. Stressors affecting treatment adherence included lack of privacy while taking drugs, unintended disclosure while obtaining drugs or seeking permission to attend clinic appointments and fear of drug adverse effects due to poor nutrition. A supportive school environment involved the availability of a school nurse, counselling services and PECs. We conclude that the school environment brings more stressors than supports for YLWHA. The daily stressors related to HIV stigma, uncertainty, disclosure, privacy and confidentiality render schooling a hassle for YLWHA. Interventions that promote resilient school communities are necessary to foster disclosure in a non-discriminatory and stigma-free environment. This calls for concerted efforts from all school stakeholders.
Stuck? No worries!: Task-aware Command Recommendation and Proactive Help for Analysts

Data analytics software applications have become an integral part of the decision-making process of analysts. Users of such a software face challenges due to insufficient product and domain knowledge, and find themselves in need of help. To alleviate this, we propose a task-aware command recommendation system, to guide the user on what commands could be executed next. We rely on topic modeling techniques to incorporate information about user's task into our models. We also present a help prediction model to detect if a user is in need of help, in which case the system proactively provides the aforementioned command recommendations. We leverage the log data of a web-based analytics software to quantify the superior performance of our neural models, in comparison to competitive baselines.
