RESUMO

Variation in prey resources influences the diet and behaviour of predators. When prey become limiting, predators may travel farther to find preferred food or adjust to existing local resources. When predators are habitat limited, local resource abundance impacts foraging success. We analysed the diet of Myotis lucifugus (little brown bats) from Nova Scotia (eastern Canada) to the Northwest Territories (north-western Canada). This distribution includes extremes of season length and temperature and encompasses colonies on rural monoculture farms, and in urban and unmodified areas. We recognized nearly 600 distinct species of prey, of which ≈30% could be identified using reference sequence libraries. We found a higher than expected use of lepidopterans, which comprised a range of dietary richness from ≈35% early in the summer to ≈55% by late summer. Diptera were the second largest prey group consumed, representing ≈45% of dietary diversity early in the summer. We observed extreme local dietary variability and variation among seasons and years. Based on the species of insects that were consumed, we observed that two locations support prey species with extremely low pollution and acidification tolerances, suggesting that these are areas without environmental contamination. We conclude that there is significant local population variability in little brown bat diet that is likely driven by seasonal and geographical changes in insect diversity, and that this prey may be a good indicator of environment quality.

RESUMO

Background: Most children and adolescents with cancer experience acute pain, and many experience longer-lasting chronic pain, negatively impacting health-related quality of life and resulting in long-term morbidity. Digital apps can aid in enhancing pain assessment and management by offering children and adolescents with cancer an accessible tool to describe their pain as a multifaceted biopsychosocial construct. Pain Squad is a useable, acceptable, and psychometrically sound multidimensional cancer pain assessment app for children and adolescents with cancer. This project aimed to evaluate the capacity to implement Pain Squad into routine pediatric oncology practice. Method: Nurse champions were asked to prescribe the Pain Squad app to patients over a 6-month implementation period. After the implementation period, we conducted audiorecorded, semistructured interviews with nurse champions to investigate the facilitators and barriers related to nurses' experiences with implementing Pain Squad. Results: The facilitators and barriers to Pain Squad implementation were organized into four overarching Consolidated Framework for Implementation Research (CFIR)-related themes: (a) characteristics of the Pain Squad app; (b) clinic setting and its context; (c) nurse implementation champions; and (d) the process of implementing Pain Squad into clinical practice. Conclusions: Interviewed nurses believed Pain Squad had the potential to improve child cancer pain care, but barriers to everyday use were evident, described in relation to the internal setting, especially the lack of compatibility between app prescription and current nurse workflows. The use of CFIR to map identified implementation facilitators and barriers can formally support the recognition of factors that may boost the chances of successful uptake.

RESUMO

OBJECTIVE: Investigations examining psychosocial adjustment among childhood cancer survivors have focused primarily on negative effects and psychopathology. Emergent literature suggests the existence of positive impact or adjustment experienced after cancer, as well. The purpose of this study is to examine the distribution of Perceived Positive Impact (PPI) and its correlates in young adult survivors of childhood cancer. METHODS: 6425 survivors and 360 siblings completed a comprehensive health survey, inclusive of a modified version of the Post-traumatic Growth Inventory (PTGI) as a measure of PPI. Linear regression models were used to examine demographic, disease and treatment characteristics associated with PPI. RESULTS: Survivors were significantly more likely than siblings to report PPI. Endorsement of PPI was significantly greater among female and non-white survivors, and among survivors exposed to at least one intense therapy, a second malignancy or cancer recurrence. Survivors diagnosed at older ages and fewer years since diagnosis were more likely to report PPI. Income, education and marital/relationship status appeared to have varied relationships to PPI depending upon the subscale being evaluated. CONCLUSIONS: The existence and variability of PPI in survivors in this study suggest that individual characteristics, inclusive of race, gender, cancer type, intensity of treatment, age at diagnosis and time since diagnosis, have unique and specific associations with different aspects of perceived positive outcomes of childhood cancer.

RESUMO

Multiple sclerosis (MS) is an inflammatory disease of the central nervous system with a significant neurodegenerative component. Dysfunctional RNA-binding proteins (RBPs) are causally linked to neuronal damage and are a feature of MS, including the mislocalization of the RBP heterogeneous nuclear ribonucleoprotein A1 (A1). Here, we show that primary neurons exposed to pro-inflammatory cytokines and anti-A1 antibodies, both characteristic of an MS autoimmune response, displayed increased A1 mislocalization, stress granule formation, and decreased neurite length, a marker of neurodegeneration. These findings illustrate a significant relationship between secreted immune factors, A1 dysfunction, and neuronal damage in a disease-relevant model system.

RESUMO

Background: Patients with inflammatory bowel disease (IBD) have an elevated risk for infection which is further increased by immunosuppressive medications. The aim of this study was to evaluate the safety and immunogenicity of influenza, PVC13, PPSV23, and hepatitis B vaccines in adults with IBD treated with vedolizumab as compared to those treated with anti-tumor necrosis factor (TNF) agents or nonimmunosuppressive therapy. Methods: In this prospective controlled trial, patients were vaccinated with the influenza, PVC13, PPSV23, and/or hepatitis B vaccines. Participants were grouped based on IBD medication regimen: (1) vedolizumab monotherapy, (2) vedolizumab plus immunomodulator, (3) anti-TNF plus immunomodulator, and (4) no immunosuppressive therapy (control). Vaccine responses were evaluated by comparing pre- and postvaccination titers. Disease activity and adverse events were monitored by the Harvey-Bradshaw Index or Simple Colitis Clinical Activity Index and by standardized phone interviews. Results: No serious adverse events or significant changes in disease activity were reported. For the influenza vaccine, baseline titers were high in all groups, and no follow-up titers met criteria for adequate response. For the pneumococcal vaccines, all groups showed response to vaccination; there was no statistically significant difference between the groups. For the hepatitis B vaccine, 62.5% of patients receiving vedolizumab and 33.3% receiving anti-TNF therapy achieved a level of response >10 mIU/mL. Discussion: The inability to observe a response to the influenza vaccine was influenced by high baseline titers. For the hepatitis B vaccine, patients treated with vedolizumab experienced immunogenic response to vaccination that was noninferior to nonimmunosuppressed controls. All studied vaccines were well-tolerated. Vaccination should be encouraged in all adult patients with IBD.

RESUMO

With increased longevity and growth in the number of older adults comes rising rates of individuals with cognitive impairment and dementia. The expansion of this population has important implications for research on aging and dementia syndromes, namely increased enrollment of older individuals in clinical research. Ethical prerogatives, as well as historical underrepresentation of persons with dementia in research studies due to the perceived burden of traditional decisional capacity evaluations, necessitates the development of pragmatic approaches to ascertain decisional abilities in research settings. We outline a protocol used in the Wisconsin Alzheimer's Disease Research Center (ADRC) that adopts a stepped approach to the evaluation of decisional capacity meant to maximize study visit efficiency while preserving participant safety and autonomy. The protocol specifies the structure of the consent process and incorporates a brief semi-structured interview based on Appelbaum & Grisso's theoretical model for evaluating a patient's decisional capacity to provide informed consent to participate in research. This protocol is easily implemented in a research study visit and is designed to minimize participant burden and ensure reliable assessment of decisional capacity in older adults across a wide range of research protocols. The protocol emphasizes capacity optimization, using memory aids and other compensatory strategies to preserve participant autonomy while protecting welfare.

RESUMO

INTRODUCTION: Pain negatively affects the health-related quality of life (HRQL) of adolescents with cancer. The Pain Squad+ smartphone-based application (app), has been developed to provide adolescents with real-time pain self-management support. The app uses a validated pain assessment and personalised pain treatment advice with centralised decision support via a registered nurse to enable real-time pain treatment in all settings. The algorithm informing pain treatment advice is evidence-based and expert-vetted. This trial will longitudinally evaluate the impact of Pain Squad+, with or without the addition of nurse support, on adolescent health and cost outcomes. METHODS AND ANALYSIS: This will be a pragmatic, multicentre, waitlist controlled, 3-arm parallel-group superiority randomised trial with 1:1:1 allocation enrolling 74 adolescents with cancer per arm from nine cancer centres. Participants will be 12 to 18 years, English-speaking and with ≥3/10 pain. Exclusion criteria are significant comorbidities, end-of-life status or enrolment in a concurrent pain study. The primary aim is to determine the effect of Pain Squad+, with and without nurse support, on pain intensity in adolescents with cancer, when compared with a waitlist control group. The secondary aims are to determine the immediate and sustained effect over time of using Pain Squad+, with and without nurse support, as per prospective outcome measurements of pain interference, HRQL, pain self-efficacy and cost. Linear mixed models with baseline scores as a covariate will be used. Qualitative interviews with adolescents from all trial arms will be conducted and analysed. ETHICS AND DISSEMINATION: This trial is approved by the Hospital for Sick Children Research Ethics Board. Results will provide data to guide adolescents with cancer and healthcare teams in treating pain. Dissemination will occur through partnerships with stakeholder groups, scientific meetings, publications, mass media releases and consumer detailing. TRIAL REGISTRATION NUMBER: NCT03632343 (ClinicalTrials.gov).

RESUMO

At the crossroads between pediatric and older adult groups, young adults with cancer may be underserved or inadequately or inappropriately served by existing support services. Empirical evidence has not established well the extent to which utilization of psychosocial support services delivered throughout a continuum of care results in desired outcomes. If self-efficacy is demonstrated to play a significant role in promoting quality of life and psychological well-being in young adult cancer patients, then a cancer-specific self-efficacy model can serve as an evidence-based framework for developing, implementing, and testing new interventions. A focus on self-efficacy has the potential to promote young adults' abilities to remain active and independent, seek and understand medical information, manage stress, cope with treatment-related side effects, maintain a "positive attitude," regulate emotions, and seek social support. Future research should aim to identify which patients represent at-risk targets for intervention, as well as the most appropriate time points along the continuum of care at which patients/survivors are most likely to benefit from delivery/utilization of psychosocial support services.

RESUMO

Hamilton and colleagues (2015) recently proposed that an integrative deficit in psychopathy restricts simultaneous processing, thereby leaving fewer resources available for information encoding, narrowing the scope of attention, and undermining associative processing. The current study evaluated this parallel processing deficit proposal using the Simultaneous-Sequential paradigm. This investigation marks the first a priori test of the Hamilton et al.'s theoretical framework. We predicted that psychopathy would be associated with inferior performance (as indexed by lower accuracy and longer response time) on trials requiring simultaneous processing of visual information relative to trials necessitating sequential processing. Results were consistent with these predictions, supporting the proposal that psychopathy is characterized by a reduced capacity to process multicomponent perceptual information concurrently. We discuss the potential implications of impaired simultaneous processing for the conceptualization of the psychopathic deficit. (PsycINFO Database Record

RESUMO

Reviews the book, Self-disclosure in psychotherapy by Barry A. Farber (see record 2006-11792-000). At one point or another, most therapists have wondered how much their patients are telling them and wrestled with how much they should reveal themselves to their patients. This book aims to provide an integrative and up-to-date review of the literature that has addressed these kinds of questions. By looking at patient, therapist, supervisee, and supervisor self-disclosure, Farber attempts to show both common and unique aspects of self-disclosure across the different parties involved in psychotherapy. Work from historical, clinical, research, and cultural perspectives comes together to provide readers with a multifaceted view of self-disclosure in psychotherapy. This book will be of interest to therapists, researchers, psychotherapy supervisors, and therapists-in-training. Farber's discussion of self-disclosure offers a nuanced perspective on the dilemmas involved in the psychotherapy process. By highlighting the features of self-disclosure across patients, therapists, supervisees, and supervisors, Farber enriches understanding of the phenomenon and encourages empathy for the perspectives of those in other psychotherapy roles. We believe that Farber has successfully synthesized work from various perspectives to create an illuminating review of self-disclosure in psychotherapy. The book condenses a broad range of literature into clearly organized and digestible chapters. The integration of research and theory with clinical vignettes, quotations from books and movies, and popular song lyrics make this work an unusually engaging and accessible read.

RESUMO

Direct relationships between induced mutation in the DCDC2 candidate dyslexia susceptibility gene in mice and changes in behavioral measures of visual spatial learning have been reported. We were interested in determining whether performance on a visual-spatial learning and memory task could be translated across species (study 1) and whether children with reading impairment showed a similar impairment to animal models of the disorder (study 2). Study 1 included 37 participants who completed six trials of four different virtual Hebb-Williams maze configurations. A 2 × 4 × 6 mixed factorial repeated measures ANOVA indicated consistency in performance between humans and mice on these tasks, enabling us to translate across species. Study 2 included a total of 91 participants (age range = 8-13 years). Eighteen participants were identified with reading disorder by performance on the Woodcock-Johnson III Tests of Achievement. Participants completed six trials of five separate virtual Hebb-Williams maze configurations. A 2 × 5 × 6 mixed factorial ANCOVA (gender as covariate) indicated that individuals with reading impairment demonstrated impaired visuo-spatial performance on this task. Overall, results from this study suggest that we are able to translate behavioral deficits observed in genetic animal models of dyslexia to humans with reading impairment. Future studies will utilize the virtual environment to further explore the underlying basis for this impairment.

RESUMO

This article introduces a novel theoretical framework for psychopathy that bridges dominant affective and cognitive models. According to the proposed impaired integration (II) framework of psychopathic dysfunction, topographical irregularities and abnormalities in neural connectivity in psychopathy hinder the complex process of information integration. Central to the II theory is the notion that psychopathic individuals are "'wired up' differently" (Hare, Williamson, & Harpur, 1988, p. 87). Specific theoretical assumptions include decreased functioning of the Salience and Default Mode Networks, normal functioning in executive control networks, and less coordination and flexible switching between networks. Following a review of dominant models of psychopathy, we introduce our II theory as a parsimonious account of behavioral and brain irregularities in psychopathy. The II theory provides a unified theoretical framework for understanding psychopathic dysfunction and integrates principle tenets of affective and cognitive perspectives. Moreover, it accommodates evidence regarding connectivity abnormalities in psychopathy through its network theoretical perspective. (PsycINFO Database Record

RESUMO

BACKGROUND: Telemedicine in an ambulatory surgical population remains incompletely evaluated. OBJECTIVE: To investigate patient encounters in the outpatient setting using video visit (VV) technology compared to traditional office visits (OVs). DESIGN, SETTING, AND PARTICIPANTS: From June 2013 to March 2014, 55 prescreened men with a history of prostate cancer were prospectively randomized. VVs, with the patient at home or at work, were included in the outpatient clinic calendar of urologists. INTERVENTION: Remote VV versus traditional OV. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: An equivalence analysis was used to assess the primary outcome, visit efficiency as measured by time studies. Secondary outcomes were patient/provider satisfaction and costs. RESULTS AND LIMITATIONS: There were 28 VVs and 27 OVs. VVs were equivalent in efficiency to relative to OVs, as measured by patient-provider face time (mean 14.5 vs 14.3min; p=0.96), patient wait time (18.4 vs 13.0min; p=0.20), and total time devoted to care (17.9 vs 17.8min; p=0.97). There were no significant differences in patient perception of visit confidentiality, efficiency, education quality, or overall satisfaction. VVs incurred lower costs, including distance traveled (median 0 vs 95 miles), travel time (0 vs 95min), missed work (0 vs 1 d), and money spent on travel ($0 vs $48; all p<0.0001). There was a high level of urologist satisfaction for both VVs (88%) and OVs (90%). The major limitation was sample size. CONCLUSIONS: VV in the ambulatory postprostatectomy setting may have a future role in health care delivery models. We found equivalent efficiency, similar satisfaction, but significantly reduced patient costs for VV compared to OV. Further prospective analyses are warranted. PATIENT SUMMARY: Among men with surgically treated prostate cancer, we evaluated the utility of remote video visits compared to office visits for outpatient consultation with a urologist. Video visits were associated with equivalent efficiency, similar satisfaction, and significantly lower patient costs when compared to office visits. We conclude that video visits may have a future role in health care delivery models.

RESUMO

Research indicates that psychopathy may be characterized by early attentional abnormalities that undermine the processing of peripheral information during goal-directed activity (Baskin-Sommers & Newman, 2012). Past work has found that psychopathic individuals show reduced interference on the Box Stroop task, in which color names are spatially separated from (i.e., peripheral to) colored stimuli (Hiatt, Schmitt, & Newman, 2004). The present study sought to replicate and extend these findings. A priori predictions were that psychopathy scores would be inversely related to interference and that psychopathy-related differences in Box Stroop conflict processing would emerge at an early stage as measured by event-related potentials (ERP). Results supported both hypotheses. Moreover, the association between the early attention-related component (N100) and interference was moderated by level of psychopathy. These findings suggest that psychopathic individuals have less coordinated responses to conflict than healthy individuals, a conjecture that has implications for information integration and self-regulation.
