RESUMO

MOTIVATION: InterARTIC is an interactive web application for the analysis of viral whole-genome sequencing (WGS) data generated on Oxford Nanopore Technologies (ONT) devices. A graphical interface enables users with no bioinformatics expertise to analyze WGS experiments and reconstruct consensus genome sequences from individual isolates of viruses, such as SARS-CoV-2. InterARTIC is intended to facilitate widespread adoption and standardization of ONT sequencing for viral surveillance and molecular epidemiology. RESULTS: We demonstrate the use of InterARTIC for the analysis of ONT viral WGS data from SARS-CoV-2 and Ebola virus, using a laptop computer or the internal computer on an ONT GridION sequencing device. We showcase the intuitive graphical interface, workflow customization capabilities and job-scheduling system that facilitate execution of small- and large-scale WGS projects on any common virus. AVAILABILITY AND IMPLEMENTATION: InterARTIC is a free, open-source web application implemented in Python that executes best-practice command line workflows from the ARTIC network. The application can be downloaded as a set of pre-compiled binaries that are compatible with all common Linux distributions, Windows with Linux subsystems, MacOSX and ARM systems. All code can be found on GitHub at https://github.com/Psy-Fer/interARTIC/ and documentation can be found at https://github.com/Psy-Fer/interARTIC/. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

RESUMO

The aim of this research was to document the content on pro-ana blogs and to uncover how the unique socio-technical features of blogs (interactivity, self-disclosure, masspersonal communication) facilitate social support among members. A final sample of 48 pro-ana blogs provided 624 individual units for coding. Results indicate that prevalent forms of social support were emotional support, esteem support, and informational support. A new category, reciprocal self-disclosure, was also revealed to be quite frequent. Blogs are spaces where social support is sought and communicated among members of the pro-ana network. Interpretation of blog communication and implications for treatment and research are discussed.

RESUMO

BACKGROUND AND PURPOSE: Building a professional brand is an important skill for student pharmacists, as this could provide them with a competitive edge given the current market environment and employment opportunities. One way to do this is through developing a personal digital brand. A pilot program was created to introduce fourth year pharmacy students to the basics of personal branding and positive uses of social media for professional development and networking. EDUCATIONAL ACTIVITY AND SETTING: A two-part workshop series was developed to introduce student pharmacists to the concept of personal digital branding and to help them optimize their professional documents (i.e. curricula vitae, resumes, and letters of intent). The workshops were offered in a virtual format and involved subject matter experts as well as alumni stakeholders. Students were asked to participate in pre- and post-surveys relating to their perceptions of professional branding and the usefulness of the workshop series. FINDINGS: Prior to the workshops, students expressed a moderate interest in using social media for professional purposes, yet few felt confident in how to do so. Following the workshops, students indicated the information provided had been beneficial, and they all had action plans for developing their social media profiles and revising their professional documents. SUMMARY: Initial findings suggested students are interested in and would benefit from training on professional branding. While this first attempt at such programming had limitations, such as being delivered to a small sample, the results provide insights for expanding and improving these offerings in the future.

RESUMO

OBJECTIVE: Social media groups for chronic pain have become increasingly popular, but the effects of these groups are largely unknown, and members may be exposed to both helpful and harmful group processes. We created a Facebook intervention for adults with chronic pain and used a mixed-methods design to evaluate the effects of group membership on social support, including examining social dynamics that may benefit or impede existing pain care. METHOD: A total of 119 adults participated in either peer-led or professionally-guided Facebook groups for 1 month. Chronic pain support was assessed at baseline, post-intervention, and 1-month follow-up, and qualitative data were collected to explore social dynamics. RESULTS: Chronic pain support increased for participants in both group types from baseline to post-intervention and then decreased at follow-up. Thematic analysis of qualitative data (i.e., participant posts and comments in response to posts) revealed an overarching theme: us versus them-a dichotomizing view of the world that distinguishes people with pain (us) versus everyone else who does not understand pain (them). Participants discussed their tendency to withdraw socially due to feeling misunderstood regarding their pain. CONCLUSIONS: Facebook groups for chronic pain enhance perceptions of support among peers. Although generally beneficial, group cohesion may facilitate an us versus them mentality, resulting in isolation and potentially poorer outcomes. Future research should explore ways to maintain benefits of the us versus them mentality, while reducing its costs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

Changes in animal movement (frequency or speed of locomotion) following exposure to a toxicant are frequently considered a biomarker of contaminant exposure and are some of the most widely reported behavioral results in toxicological literature. However, the ecological consequences of such behavioral changes, such as effects on toxicant transfer in foodwebs, are far less well understood, complicated in part by the short-term nature of laboratory experiments and the lack of complementary field studies where the nature of toxicant exposure is more complex. Here we examine whether naturally exposed individuals of the round goby, a benthic, site-loyal fish, move in a manner similar to conspecifics from less contaminated habitats. In the laboratory, round goby from a relatively cleaner site showed greater activity and exploration than goby from two highly contaminated sites. Male fish were more active than females but the site effects were similar in both sexes. In contrast to laboratory findings, a field mark-recapture study of 881 round goby showed that fish from the cleaner site did not move greater distances or exhibit shorter residence times within the site than round goby from highly contaminated sites. Our results indicate that while behavioral changes in the laboratory may be one of several useful diagnostics of toxicant exposure of wild-exposed animals, they do not necessarily translate readily into measurable differences in a natural context. Thus, the potential fitness consequences of toxicant exposure based on behavioral changes need to be assessed carefully.

RESUMO

Despite the popularity and affordances of social media groups for people with chronic conditions, there have been few controlled tests of the effects of these groups. This randomized controlled superiority trial examined the effects of Facebook groups on pain-related outcomes and tested whether a professional-led group leads to greater effects than a support group alone. We randomly assigned 119 adults with chronic pain to one of two Facebook group conditions: a standard condition (n = 60) in which participants were instructed to offer mutual support, or a professional-led condition (n = 59) in which the investigators disseminated empirically-supported, socially-oriented psychological interventions. Four groups were run (2 standard, 2 professional-led), each lasting 4 weeks and containing approximately 30 participants. Measures were administered at baseline, post-intervention, and 1-month follow-up. Across conditions, participants improved significantly in primary outcomes (pain severity and interference; medium-large effects) and a secondary outcome (depressive symptoms; small-medium effect), and they retained their outcomes 1 month after the groups ended. The 2 conditions did not differ on improvements. Overall, this study supports the use of social media groups as an additional tool to improve chronic pain-related outcomes. Our findings suggest that professional intervention may not have added value in these groups and that peer support alone may be driving improvements. Alternatively, the psychosocial intervention components used in the current study might have been ineffective, or more therapist direction may be warranted. Future research should examine when and how such guidance could enhance outcomes. PERSPECTIVE: Findings from this randomized trial support the use of both standard and professional-led Facebook groups as an accessible tool to enhance the lives of adults with chronic pain. This article provides direction for how to improve social media groups to optimize outcomes and satisfaction for more users.

RESUMO

Objective: This study investigated how affect influences people's processing of messages about risks and benefits of using autonomous artificial intelligence (AI) technology to screen for skin cancer. We examined integral affect (emotion derived during decision making) separately from incidental affect (extraneous mood states). Design: Using the affect heuristic framework, we randomly assigned 273 participants to conditions featuring risk (high, low, uncertain) or benefit (high, low, uncertain) messages about AI. Following 'affect-as-spotlight', we also explored whether people's integral affect towards skin cancer moderated the relationship between risk/benefit messages and AI screening intentions. Outcomes: Perceived risk, perceived benefit, positive and negative affect toward AI, intention to use AI screening. Results: After controlling for incidental affect and risk perceptions, we found that compared to low risk messages, uncertain risk messages increased participants' negative affect toward AI, decreased positive affect toward AI, increased AI risk evaluations and reduced AI benefit evaluations. Perceptual variables significantly mediated participants' intentions to use AI for risk messages but not benefit messages. No moderation effects were found. Conclusions: Results suggest extending the affect heuristic framework to include uncertain risk conditions. Integral AI affect influenced people's interpretation of messages, which then impacted likelihood to use AI technology for health.

RESUMO

Immune responses to therapeutic transgenes are a potential hurdle to treat monogenic muscle disorders. These responses result from the neutralizing activity of transgene-specific B cells and cytotoxic T cells recruited upon gene transfer. We explored here how dual muscle-liver expression of a foreign transgene allows muscle transgene engraftment after adenoassociated viral vector delivery. We found in particular that induction of transgene-specific tolerance is imposed by concurrent muscle and liver targeting, resulting in the absence of CD8+ T cell responses to the transgene. This tolerance can be temporally decoupled, because transgene engraftment can be achieved in muscle weeks after liver transduction. Importantly, transgene-specific CD8+ T cell tolerance can be established despite preexisting immunity to the transgene. Whenever preexisting, transgene-specific CD4+ and CD8+ memory T cell responses are present, dual muscle-liver transduction turns polyclonal, transgene-specific CD8+ T cells into typically exhausted T cells with high programmed cell death 1 (PD-1) expression and lack of IFN-γ production. Our results demonstrate that successful transduction of muscle tissue can be achieved through liver-mediated control of humoral and cytotoxic T cell responses, even in the presence of preexisting immunity to the muscle-associated transgene.

RESUMO

Wine is produced by one of two methods: inoculated fermentation, where a commercially-produced, single Saccharomyces cerevisiae (S. cerevisiae) yeast strain is used; or the traditional spontaneous fermentation, where yeast present on grape and winery surfaces carry out the fermentative process. Spontaneous fermentations are characterized by a diverse succession of yeast, ending with one or multiple strains of S. cerevisiae dominating the fermentation. In wineries using both fermentation methods, commercial strains may dominate spontaneous fermentations. We elucidate the impact of the winery environment and commercial strain use on S. cerevisiae population structure in spontaneous fermentations over two vintages by comparing S. cerevisiae populations in aseptically fermented grapes from a Canadian Pinot Noir vineyard to S. cerevisiae populations in winery-conducted fermentations of grapes from the same vineyard. We also characterize the vineyard-associated S. cerevisiae populations in two other geographically separate Pinot Noir vineyards farmed by the same winery. Winery fermentations were not dominated by commercial strains, but by a diverse number of strains with genotypes similar to commercial strains, suggesting that a population of S. cerevisiae derived from commercial strains is resident in the winery. Commercial and commercial-related yeast were also identified in the three vineyards examined, although at a lower frequency. There is low genetic differentiation and S. cerevisiae population structure between vineyards and between the vineyard and winery that persisted over both vintages, indicating commercial yeast are a driver of S. cerevisiae population structure. We also have evidence of distinct and persistent populations of winery and vineyard-associated S. cerevisiae populations unrelated to commercial strains. This study is the first to characterize S. cerevisiae populations in Canadian vineyards.

RESUMO

Many studies document how individuals use Facebook to meet partners or develop and maintain relationships. Less is known about information-seeking behaviors during the stages of relationship termination. Relational dissolution is a socially embedded activity, and affordances of social network sites offer many advantages in reducing uncertainty after a breakup. A survey collected responses from 110 individuals who use Facebook to gather information about their romantic ex-partners. Results indicated that after breakup, partners may take advantage of the system's information visibility and the relative invisibility of movement depending on relational factors (initiator role and breakup uncertainty), social factors (perceived network approval of Facebook surveillance), and individual privacy concerns. This investigation addresses questions such as what type of information-seeking foci do individuals employ and how do individuals use Facebook as a form of surveillance? What factors motivate surveillance behavior?
