RESUMEN
Psychological theories of mobilization tend to focus on explaining people's motivations for action, rather than mobilization ("activation") processes. To investigate the online behaviors associated with mobilization, we compared the online communications data of 26 people who subsequently mobilized to right-wing extremist action and 48 people who held similar extremist views but did not mobilize (N = 119,473 social media posts). In a three-part analysis, involving content analysis (Part 1), topic modeling (Part 2), and machine learning (Part 3), we showed that communicating ideological or hateful content was not related to mobilization, but rather mobilization was positively related to talking about violent action, operational planning, and logistics. Our findings imply that to explain mobilization to extremist action, rather than the motivations for action, theories of collective action should extend beyond how individuals express grievances and anger, to how they equip themselves with the "know-how" and capability to act.
RESUMEN
AIMS: To explore the effect or potential effect of alcohol marketing in people with an alcohol use disorder, in recovery from an alcohol use disorder, and hazardous and harmful drinkers. METHODS: Relevant literature was identified by searching Medline (OVID), EMBASE (OVID), and PsycINFO (OVID) and relevant websites. Both quantitative and qualitative studies were eligible for inclusion. A narrative approach was used to synthesize the findings. RESULTS: The review included 10 studies. Two quantitative and three qualitative studies focused on participants recovering from an alcohol use disorder and five quantitative studies on those with hazardous or harmful consumption levels of alcohol. The effect of alcohol advertising on alcohol use was only assessed in one study, a small experimental study of young adult heavy drinkers, which found no significant association. Studies looking at other outcomes found that people with or at risk of alcohol problems were likely to notice alcohol advertisements and find them appealing, and that advertisements may have an effect on positive alcohol-related emotions and cognitions. Among people in recovery from an alcohol use disorder, findings suggested that there could be an effect on craving, and that alcohol marketing may be perceived to trigger a desire to drink. CONCLUSIONS: Alcohol marketing is likely to have an effect on alcohol consumption in people with, or at increased risk of, an alcohol problem. Studies have also found that alcohol marketing is perceived to act as a trigger by people in recovery from alcohol problems. SUMMARY: A rapid review explored the effect of alcohol marketing in people with an alcohol use disorder, in recovery from an alcohol use disorder, and hazardous and harmful drinkers. The findings of the 10 included studies suggest that an effect of alcohol marketing in these populations is likely.

RATIONALE AND OBJECTIVES: Diagnostic momentum refers to ruling in a particular diagnosis without adequate evidence. As the field of physical therapy continues to transition more towards autonomous practitioners with direct access, there is a need to identify the effect of a physician diagnosis on a therapist's examination and treatment. The purpose of this study was to identify if diagnostic momentum exists in physical therapy and whether this phenomenon could affect the ability of the therapist to identify clinical red flags. METHODS: An online survey with randomized case scenarios was completed by 75 licensed practicing physical therapists. Participants received one of two scenarios: a case vignette where the patient was referred to physical therapy for left shoulder pain and presented with 'red flags' indicative of myocardial infarction, or a similar vignette with additional results from an exercise stress test that ruled out myocardial infarction. The subjects were asked if they would 'treat' or 'refer' to another healthcare provider and the reason behind their decision. Independent t-tests and χ2 analyses were conducted to understand the differences between the groups. A thematic analysis was used to explore the therapists' responses regarding the reasoning for their decision. RESULTS: There was no significant difference in clinical decision making based on age, gender, years of experience, advanced certification, primary caseload or primary practice setting. Among those who received the case without the stress test, 31.4% of participants indicated that they would refer, compared to 12.5% of the participants that had the additional stress test result included within their case. The presence of the negative stress test was indicated as the main reason for choosing to treat without referral by 65.7% of the subjects that received the additional stress test result. CONCLUSION: This study suggests that practicing physical therapists may be influenced by diagnostic decisions made by other clinicians, causing them to overlook signs and symptoms of possible myocardial infarction.

Since 2009, there has been an increase in global protests and related online activity. Yet, it is unclear how and why online activity is related to the mobilization of offline collective action. One proposition is that online polarization (or a relative change in intensity of posting mobilizing content around a salient grievance) can mobilize people offline. The identity-norm nexus and normative alignment models of collective action further argue that to be mobilizing, these posts need to be socially validated. To test these propositions, across two analyses, we used digital traces of online behavior and data science techniques to model people's online and offline behavior around a mass protest. In Study 1a, we used Twitter behavior posted on the day of the protest by attendees or nonattendees (759 users; 7,592 tweets) to train and test a classifier that predicted, with 80% accuracy, who participated in offline collective action. Attendees used their mobile devices to plan logistics and broadcast their presence at the protest. In Study 1b, using the longitudinal Twitter data and metadata of a subset of users from Study 1a (209 users; 277,556 tweets), we found that participation in the protest was not associated with an individual's online polarization over the year prior to the protest, but it was positively associated with the validation ("likes") they received on their relevant posts. These two studies demonstrate that rather than being low cost or trivial, socially validated online interactions about a grievance are actually key to the mobilization and enactment of collective action.

Objectives. Adherence to treatment recommendations is critical for optimising quality of life for individuals with chronic pain, however adherence rates are low. This study explores the role that significant others are perceived to play in supporting or impeding treatment adherence, as well as examining patient views of the impact of their adherence regimes on their significant others.Design. 25 treatment seeking adults with chronic pain, who were currently living with a romantic partner or adult family member, took part in individual semi-structured interviews.Main outcome measures Interviews were transcribed verbatim and analysed using thematic analysis.Results. Three treatment adherence support themes emerged: social support (emotional, instrumental), positive social control, and supporting autonomy. Participants did not perceive significant others as having any negative influence on their adherence. By contrast, patients perceived that their adherence behaviors had both positive and negative effects on their significant others.Conclusions. These data present an encouraging perspective on the interpersonal context of coping with chronic pain. Significant others facilitated adherence in a range of ways. Future research identifying how best to integrate significant other support into patient self-management programs is needed, in order to lift the poor treatment adherence rates that are noted in the literature.
RESUMEN
This paper provides practitioner and academic insights into the importance of examining non-technical skills in a multiteam system emergency response. The case of public health professionals is highlighted, illustrated with unique qualitative field data which focused upon the use of non-technical skills at a meso level of analysis. Results reflected the importance of context upon the multiteam system and highlighted seven non-technical skills used by public health professionals to support an effective response. Recommendations for future research and implications for practice are noted for this hard to access professional group, located within emerging advances in the scientific inquiry of complex and increasingly evident, multi-team systems.
RESUMEN
The internet is often viewed as the source of a myriad of benefits and harms. However, there are problems with using this notion of "the internet" and other high-level concepts to explain the influence of communicating via everyday networked technologies on people and society. Here, we argue that research on social influence in computer-mediated communication (CMC) requires increased precision around how and why specific features of networked technologies interact with and impact psychological processes and outcomes. By reviewing research on the affordances of networked technologies, we demonstrate how the relationship between features of "the internet" and "online behaviour" can be determined by both the affordances of the environment and the psychology of the user and community. To achieve advances in this field, we argue that psychological science must provide nuanced and precise conceptualisations, operationalisations, and measurements of "internet use" and "online behaviour". We provide a template for how future research can become more systematic by examining how and why variables associated with the individual user, networked technologies, and the online community interact and intersect. If adopted, psychological science will be able to make more meaningful predictions about online and offline outcomes associated with communicating via networked technologies.

OBJECTIVE: Chronic lymphocytic leukemia and small lymphocytic lymphoma remain the most prevalent adult leukemia in Western countries. Novel therapeutics have established long-term efficacy and have changed the landscape in patient management. In contrast, novel approaches pose opportunities for patients to be treated for finite durations. In this manuscript, we highlight long-term safety and efficacy data with Bruton's tyrosine kinase inhibitors and combination BCL2 + anti-CD20 therapies. We also offer key considerations for treatment selection and outline ongoing trials which may continue to expand therapeutic options and approaches. DATA SOURCES: An electronic search of the PubMed database was performed to obtain key literature in chronic lymphocytic leukemia and small lymphocytic lymphoma published using the following search terms: chronic lymphocytic leukemia/small lymphocytic lymphoma, Richter syndrome, and histologic transformation. The search results were narrowed by selecting studies in humans published in English. Results were confined to the following article types: Clinical Trial, Phase II; Clinical Trial, Phase III; Clinical Trial, Phase IV; Guideline; Randomized Controlled Trial; Meta-Analysis; Systematic Reviews; and Validation Studies. DATA SUMMARY: Chronic lymphocytic leukemia and small lymphocytic lymphoma are different manifestations of the same disease and are managed in much the same way. Bruton's tyrosine kinase inhibitors have demonstrated long and durable efficacy benefits in patients with newly diagnosed chronic lymphocytic leukemia/small lymphocytic lymphoma and in the relapsed/refractory setting. Despite these benefits, long terms adverse events have posed challenges for patients and have led to treatment discontinuations. Additionally, the use of monotherapy Bruton's tyrosine kinase inhibitor's requires chronic use of the medications leading to added financial implications. BCL2 inhibition with venetoclax in combination with anti-CD20 monoclonal antibodies has offered a novel and finite treatment approach in frontline and relapsed chronic lymphocytic leukemia/small lymphocytic lymphoma. Ongoing clinical trials are in investigating this modality further to enhance durable responses utilizing a combination Bruton's tyrosine kinase inhibitor's and BCL2 inhibitors. CONCLUSION: The treatment armamentarium of chronic lymphocytic leukemia/small lymphocytic lymphoma continues to evolve. Despite the long term, durable responses with Bruton's tyrosine kinase inhibitor's, it is likely that finite treatment durations could become the standard of care as a result of continued, long-term responses.

With the introduction of the anterior locking plate in the early part of this century, there was a large change in how distal radial fractures were treated. Early articles about the techniques reported tendon ruptures occurring in as many as 10%, although studies from our unit reported rates closer to 2%. Subsequent refinements in surgical technique and improvements in plate design have been made with the aim of reducing the number of ruptures. Despite this, the original articles and their rates continue to be quoted. In this retrospective study of 798 cases treated with anterior locking plates, tendon ruptures have been significantly reduced and are now as low as 0.5%. Contributing factors leading to this improvement are identified and discussed.Level of evidence: III.

Academic medical centers (AMCs) face challenges in conducting research among traditionally marginalized communities due to long-standing community mistrust. Evidence suggests that some AMC faculty and staff lack an understanding of the history of distrust and social determinants of health (SDH) affecting their communities. Wake Forest Clinical and Translational Science Institute Program in Community Engagement (PCE) aims to build bridges between communities and Wake Forest Baptist Health by equipping faculty, clinicians, administrators, and staff (FCAS) with a better understanding of SDH. The PCE collaborated with community partners to develop and implement community tours to improve cross-community AMC understanding and communication, enhance knowledge of SDH, and build awareness of community needs, priorities, and assets. Nine day-long tours have been conducted with 92 FCAS. Tours included routes through under-resourced neighborhoods and visits to community assets. Participant evaluations assessed program quality; 89% reported enhanced understanding of access-to-care barriers and how SDH affect health; 86% acknowledged the experience would improve future interactions with participants and patients; and 96% agreed they would recommend the tour to colleagues. This work supports the use of community tours as a strategy to improve cross-community AMC communication, build trust, and raise awareness of community needs, priorities, and assets.
RESUMEN
Factors that promote versus protect against body dissatisfaction remain unclear. Social media may be a risk factor, particularly given ubiquitous engagement among young people, and the pervasive use of "selfies." Conversely, self-compassion has received attention as a protective factor against body dissatisfaction. This study examined: (a) the relationships between "manipulation" of selfies posted online, "investment" in others' responses to selfies, and body dissatisfaction; and (b) whether self-compassion moderated the relationships between social media variables and body dissatisfaction. Results from 184 Australian men (n = 89) and women (n = 95) suggested that social media variables photo manipulation and investment were associated with greater body dissatisfaction for both genders. Self-compassion did not moderate these relationships. Findings suggest that manipulation and concern about selfies posted may be risk correlates for body dissatisfaction in men and women. Further research is needed to investigate protective factors against body dissatisfaction in an online environment.

INTRODUCTION: The goal of this study was to explore the efficacy and tolerability of metronomic chemotherapy, a novel anti-angiogenic treatment strategy, in combination with bevacizumab in patients with advanced non-small cell lung cancer (NSCLC). METHODS: Subjects with newly diagnosed stage IV NSCLC were treated with 4-week cycles of paclitaxel 80mg/m2 and gemcitabine 300mg/m2 weekly for three weeks, plus bevacizumab 10mg/kg every two weeks. Radiologic assessments were performed every 8 weeks. The primary endpoint was progression free survival (PFS). An exploratory objective was to correlate plasma levels of angiogenic biomarkers with treatment response. RESULTS: Thirty-nine subjects were included in the intent to treat (ITT) analysis. The objective response rate (ORR) was 56%, the median PFS was 8.5 months, and median overall survival (OS) was 25.5 months. The PFS rate at 6, 12, and 24 months was 61%, 21%, and 11% respectively. The OS rate at 12 and 24 months was 74% and 53% respectively. Treatment was well tolerated, without significant myelosuppressive, gastrointestinal, or neurologic events. Subjects with less than median baseline values of angiopoietin-2 and IL-8 experienced significantly longer PFS. Longer OS was associated with subjects with less than the median baseline values for PLGF and angiopoietin-2. There were statistically significant differences in median values of several biomarkers between cycles 1 and 3 in subjects with objective responses. CONCLUSIONS: The combination of paclitaxel and gemcitabine, delivered in a metronomic schedule, in combination with bevacizumab, appears to be an effective and tolerable treatment strategy in patients with advanced NSCLC.

BACKGROUND: In Drosophila early post-meiotic spermatids, mitochondria undergo dramatic shaping into the Nebenkern, a spherical body with complex internal structure that contains two interwrapped giant mitochondrial derivatives. The purpose of this study was to elucidate genetic and molecular mechanisms underlying the shaping of this structure. RESULTS: The knotted onions (knon) gene encodes an unconventionally large testis-specific paralog of ATP synthase subunit d and is required for internal structure of the Nebenkern as well as its subsequent disassembly and elongation. Knon localizes to spermatid mitochondria and, when exogenously expressed in flight muscle, alters the ratio of ATP synthase complex dimers to monomers. By RNAi knockdown we uncovered mitochondrial shaping roles for other testis-expressed ATP synthase subunits. CONCLUSIONS: We demonstrate the first known instance of a tissue-specific ATP synthase subunit affecting tissue-specific mitochondrial morphogenesis. Since ATP synthase dimerization is known to affect the degree of inner mitochondrial membrane curvature in other systems, the effect of Knon and other testis-specific paralogs of ATP synthase subunits may be to mediate differential membrane curvature within the Nebenkern.

This study examined attachment relationships and emotional distress after the passing of a pet. Participants were 73 university students 17-26 years of age who had lost a family pet within the past 5 years. They completed measures of attachment styles toward people and their pet, as well as complicated grief, depression, and trauma. As hypothesized, there were positive relations between attachments with people and pets, and anxiety in pet attachment was positively related to complicated grief, even when attachment with people was controlled. Results are discussed in terms of the importance of attachment style to grief over loss.

OBJECTIVE: Resins used in dental composites, derived from bisphenol-A (BPA), have been shown to alter immune cells. The objective of this study was to explore children's immune function changes in relation to resin composite treatment. DESIGN: We conducted secondary data analysis of the New England Children's Amalgam Trial immune function substudy (N = 59). Immune function was measured pre-treatment and up to five times post-treatment through 5-year follow-up. Multivariable generalized linear regression models were used to estimate the association between three classes of resin composites (bisphenol-A-diglycidyl-dimethacrylate [BisGMA]-based flowables used for preventive sealants; urethane dimethacrylate [UDMA]-based compomer restorations; bisGMA-based restorations) and changes in immune function markers measured annually. RESULTS: Total white blood cell counts and responsiveness of T cells or neutrophils were not appreciably altered by composite treatment levels. Changes in B cell responsiveness were greater throughout follow-up among children with more bisGMA-based composite restorations, which opposed findings for amalgam treatment levels. Monocyte responsiveness changes were decreased at 6 months with greater treatment, but not over longer follow-up. CONCLUSIONS: Results of this analysis showed no overt immune function alterations associated with resin composites. Additional research regarding lymphocyte activation may be warranted given the consistency of results within these analyses and with a prior study showing increased B cell activation.

Zebrafish are ideal for experimental studies in the classroom because, in contrast to chicks or mammals, fish embryos are relatively easy and inexpensive to maintain, and embryonic development can be observed with common classroom equipment. The eight student-developed laboratory exercises described here have been used by students in Neuroscience Research at Sidwell Friends School. This course uses zebrafish as a vertebrate model to study genetics, development, behavior, neurobiology, regeneration, learning, and memory. The students develop protocols through collaboration with the teacher and scientists in specific fields. Through individual research, students develop and perform their own experiments, formulate and test hypotheses, learn basic laboratory and microscopy techniques, collect and analyze data, read original scientific literature, and collaborate with prominent zebrafish researchers.
