Embodying or resisting social normativity? A carnal inquiry into exercise addiction experiences.

Exercise addiction has sparked a growing interest in the scientific and clinical literature, yet this behavioral addiction has mainly been investigated quantitatively, from a positivistic perspective. This article explores the subjective and embodied dimensions of exercise addiction, broadening current conceptions of this emerging, still unofficial mental health category. Building on carnal sociology, and through a thematic analysis of mobile interviews conducted with 17 self-proclaimed "exercise addicts" from Canada, this article examines the interrelations between the embodiment of exercise addiction and the normative social elements at stake in the shaping of the category, providing insights on how exercise is experienced as an addiction. Results show that most participants describe this addiction as "soft" and "positive", highlighting the virtues of exercising. However, their bodily accounts also reveal a suffering body, bringing forth the vices related to excessive exercising. Participants also put in relation the quantifiable and the sensible body, revealing the porous boundaries of this construct: exercise addiction can sometimes be regulatory in certain contexts and counternormative in others. Thus, it appears that "exercise addicts" enact various contemporary normative requirements, which vary from asceticism and body-ideals but also to the phenomenon of social and temporal acceleration. We argue that exercise addiction questions how certain behaviors, deemed potentially problematic, illustrate the tensions and complex articulations between embodying and resisting social normativity.

eLoriCorps Immersive Body Rating Scale and eLoriCorps Mobile Versions: Validation to Assess Body Image Disturbances from Allocentric and Egocentric Perspectives in a Nonclinical Sample of Adolescents.

A growing number of studies have used virtual reality (VR) for the assessment and treatment of body image disturbances (BIDs). This study, conducted in a community sample of adolescents, documents the convergent and discriminant validity between (a) the traditional paper-based Figure Rating Scale (paper-based FRS), (b) the VR-based Body Rating Scale (eLoriCorps-IBRS 1.1), and (c) the mobile app-based Body Rating Scale (eLoriCorps-IBRS 1.1-Mobile). A total of 93 adolescents (14 to 18 years old) participated in the study. Body dissatisfaction and body distortion were assessed through the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. Eating disorder symptoms, body image avoidance, and social physique anxiety were also measured. Correlation analyses were performed. Overall, the results showed a good and statistically significant convergence between allocentric perspectives as measured by the paper-based FRS, the eLoriCorps-IBRS 1.1 and the eLoriCorps-IBRS 1.1-Mobile. As expected, the egocentric perspective measured in VR produced different results from the allocentric perspective, and from cognitive-attitudinal-affective dimensions of BIDs, with the exception of body distortion. These differences support the discriminant validity of the egocentric perspective of eLoriCorps-IBRS 1.1 and are consistent with emerging evidence, highlighting a difference between experiencing the body from an egocentric (i.e., the body as a subject) and allocentric (i.e., the body as an object) perspective. The egocentric perspective could reflect a perceptual-sensory-affective construction of BIDs, whereas allocentric measures seem to be more related to a cognitive-affective-attitudinal construction of BIDs. Moreover, the results support the validity of the eLoriCorps-IBRS 1.1-Mobile with promising perspectives of implementation among young populations.

Graphene Whisperitronics: Transducing Whispering Gallery Modes into Electronic Transport.

When confined in circular cavities, graphene relativistic charge carriers occupy whispering gallery modes (WGMs) in analogy to classical acoustic and optical fields. The rich geometrical patterns of the WGMs decorating the local density of states offer promising perspectives to devise new disruptive quantum devices. However, exploiting these highly sensitive resonances requires the transduction of the WGMs to the outside world through source and drain electrodes, a yet unreported configuration. Here, we create a circular p-n island in a graphene device using a polarized scanning gate microscope tip and probe the resulting WGM signatures in in-plane electronic transport through the p-n island. Combining tight-binding simulations and the exact solution of the Dirac equation, we assign the measured device conductance features to WGMs and demonstrate mode selectivity by displacing the p-n island with respect to a constriction. This work therefore constitutes a proof of concept for graphene whisperitronic devices.

The FitSpirit approach for increasing physical activity in canadian teenage girls: protocol of a longitudinal, quasi-experimental study.

BACKGROUND: Worldwide, most adolescent girls do not meet physical activity (PA) recommendations and very few PA programs are tailored specifically towards them. Even fewer information exists about the long-term effects of such programs. Some Canadian schools have implemented the FitSpirit PA intervention designed specifically for girls aged 12 to 17 years old. This paper describes the protocol of a quasi-experimental study evaluating long-term changes in health behaviours and outcomes following FitSpirit participation. METHODS: The study is conducted among schools that partner with FitSpirit every year. It started in 2018 and will be completed in 2022. The intervention comprises motivational talks, a turnkey running program, PA sessions and special events. Study participants fill out an online questionnaire twice a year. Follow-up questionnaires are sent at the end of each school year to the study participants who dropout from FitSpirit. The main outcome, changes in PA levels, is evaluated using questions validated for adolescents. Secondary outcomes are health (perceived health); lifestyle habits (sedentary activities, eating and sleeping habits); psychosocial outcomes (physical self-efficacy and body satisfaction); and FitSpirit appreciation (activity participation and satisfaction). Most questions originate from questionnaires validated for the adolescent population. Cross-sectional and longitudinal analyses will be performed. DISCUSSION: This study will provide one of the first longitudinal reports on the impact of a large extra-curricular PA intervention designed specifically for adolescent girls. The current study will uniquely contribute to PA research by assessing outcomes additional to PA levels, including markers of health, lifestyle habits and psychosocial determinants. TRIAL REGISTRATION: NCT, NCT03804151 , Registered on January 22, 2019; retrospectively registered.

Changes in Lifestyle Habits among Adolescent Girls after FitSpirit Participation.

Adolescence is a crucial time in the development and maintenance of lifestyle habits. Interventions to improve health-related behaviors are important, including those that can contribute to an increase in physical activity (PA). During adolescence, PA typically decreases with age, particularly in girls. The FitSpirit program offers services that help Canadian schools from Quebec and Ontario implement PA interventions for adolescent girls. This study aimed to evaluate changes in participants' PA levels and lifestyle habits (sedentary time, sleep duration and eating habits) and to assess whether these changes depended on adherence to the Canadian 24-Hour Movement Guidelines and Canada's Food Guide recommendations at enrollment. At the time of FitSpirit registration (between December 2018 and March 2019) and in May/June 2019, 73 participants answered online questionnaires. The participants reported improvements, with an increase in the number of days with PA and a decrease in daily consumption of sweets. The greatest changes were observed in those who did not adhere to the Canadian recommendations before enrollment and who significantly increased their number of days with PA and their consumption of fruits and vegetables, and decreased their screen time. In conclusion, participation in FitSpirit improved several health behaviors among adolescent girls, particularly those who did not comply with the Canadian recommendations at enrollment.

What Is Our "Epistemic Responsibility"? Reflections on Social Work's Orientation in Yoga Therapy Research.

The purpose of this article is to explore how the social work discipline could provide a complementary lens through which yoga therapy can be analyzed and evaluated by engaging in knowledge-creation practices and procedures that prioritize the "epistemic responsibility" described by philosopher Lorraine Code. More specifically, by seeking to strategically include often-subjugated types of knowledge and by focusing on redistributing epistemic power to agents that typically have been excluded from epistemic participation in contemporary yoga therapy research, the social work discipline, with its strong commitment to social justice, has the potential to contribute to filling an important gap in scientific literature. We begin by presenting the relevance of the social work perspective in relation to the field of yoga therapy. We next offer a reserved critical analysis of the dominant technical knowledge base that currently informs yoga therapy practice. This analysis highlights the social parameters that may be rendered invisible or left aside when adopting a positivist epistemological lens and justifies how the conceptual apparatus of epistemic responsibility serves as a potential platform for rethinking social work's position and future contributions to the field of yoga therapy. Finally, we mobilize the concept of cultural appropriation to illustrate how striving for epistemic responsibility provides an entry point for addressing the multilevel, complex social processes embedded in yoga therapy practice and research while aiming to capture the many voices-and hence the various truths-implicated in a democratic, reflexive, and inclusive research process.

Ebola and Localized Blame on Social Media: Analysis of Twitter and Facebook Conversations During the 2014-2015 Ebola Epidemic.

This study aimed to analyze main groups accused on social media of causing or spreading the 2014-2016 Ebola epidemic in West Africa. In this analysis, blame is construed as a vehicle of meaning through which the lay public makes sense of an epidemic, and through which certain classes of people become "figures of blame". Data was collected from Twitter and Facebook using key word extraction, then categorized thematically. Our findings indicate an overall proximate blame tendency: blame was typically cast on "near-by" figures, namely national governments, and less so on "distant" figures, such as generalized figures of otherness ("Africans", global health authorities, global elites). Our results also suggest an evolution of online blame. In the early stage of the epidemic, blame directed at the affected populations was more prominent. However, during the peak of the outbreak, the increasingly perceived threat of inter-continental spread was accompanied by a progressively proximal blame tendency, directed at figures with whom the social media users had pre-existing biopolitical frustrations. Our study proposes that pro-active and on-going analysis of blame circulating in social media can usefully help to guide communications strategies, making them more responsive to public perceptions.

The critical reception of the DSM-5: Towards a typology of audiences.

Since its initial publication, the Diagnostic and Statistical Manual of Mental Disorders has been the object of criticism which has led to regular revisions by the American Psychiatric Association. This article analyses the debates that surrounded the publication of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.). Building on the concepts of public arenas and reception theory, it explores the meaning encoded in the manual by audiences. Our results, which draw from a thematic analysis of traditional and digital media sources, identify eight audiences that react to the American Psychiatric Association's narrative of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.): conformist, reformist, humanist, culturalist, naturalist, conflictual, constructivist and utilitarian. While some of their claims present argumentative polarities, others overlap, thus challenging the idea, often presented in academic publications, of a fixed debate. In order to further discuss on the Diagnostic and Statistical Manual of Mental Disorders, we draw attention to claims that 'travel' across different communities of audiences.

Neutrophil-to-Lymphocyte Ratio Predicts Death in Acute-on-Chronic Liver Failure Patients Admitted to the Intensive Care Unit: A Retrospective Cohort Study.

The neutrophil-to-lymphocyte ratio (NLR) is an inflammation score recognized as associated with outcome. Although inflammation has been shown to correlate with the development of acute-on-chronic liver failure (ACLF), we sought to investigate the role of NLR in predicting 90-day mortality in cirrhotic patients experiencing ACLF. We performed a retrospective cohort study involving a total of 108 consecutive cirrhotic patients admitted in the intensive care unit (ICU). NLR, clinical and biological data were recorded. Of the total, 75 patients had ACLF. The 90-day mortality rate was 53%. ACLF patients displayed higher NLR values in comparison with cirrhotic patients without ACLF throughout the ICU stay. NLR proved more elevated in nonsurvivors ACLF patients, with mortality correlating with increasing quartiles of NLR. On multivariable Cox regression analysis, NLR was found to be a predictor of mortality along with the Sequential Organ Failure Assessment (SOFA) score and mechanical ventilation requirement. The model for end-stage liver disease (MELD) score was not predictive of 90-days mortality. Performance analysis revealed an area under curve of 0.71 [95% confidence interval: 0.59-0.82] regarding NLR capacity to predict 90-days mortality. When including NLR, SOFA score, and mechanical ventilation requirement into the final model, the area under curve was significantly higher (0.81 [95% confidence interval: 0.72-0.91]).These findings suggest that NLR is associated with mortality in ACLF patients admitted to the ICU. Combining NLR, SOFA score, and the need for mechanical ventilation could be a useful prognostic tool to identify ACLF patients at a higher risk of mortality.

Current Trends in Theoretical Orientation of Psychologists: The Case of Quebec Clinicians.

OBJECTIVE: Trends indicate that clinical psychologists' theoretical orientations have changed over the last decades in North America, but research on this topic in Canada is scarce. We analyzed the orientation of psychologists over the last 20 years in the province of Quebec, where 46% of Canadian psychologists are located. METHOD: Data were collected annually through the board registration form of Quebec psychologists' professional order from 1993 to 2013. Univariate statistical analyses were realized on aggregated data. RESULTS: In 20 years, the proportion of clinicians choosing cognitive-behavioral therapy (CBT) as their main orientation grew from 18.4% to 38%, while preference for other orientations slightly declined. Existential-humanistic and psychodynamic-psychoanalytic approaches remained the primary orientation for around 21.7% and 21.5%, respectively. In 2013 (N = 8608), when taking into account 2 choices of theoretical orientation, 55.8% of clinicians chose CBT, 34.3% existential-humanistic orientation, 27.9% psychodynamic-analytic theories, and 21.8% systemic-interactional orientation. CONCLUSIONS: Findings underline trends in Quebec clinical practice characterized by an increase in the number of psychologists identifying cognitive-behavioral approach as their primary self-reported theoretical orientation.

The neutrophil-to-lymphocyte ratio (NLR) after surgery for hip fracture (HF).

BACKGROUND: The NLR is a prognostic factor for outcome and survival in cardiology, oncology and digestive surgery. NLR has not yet been studied in HF. METHODS: Retrospective analysis of a prospective cohort of 247 consecutive patients, older than 65 years, operated for HF. Mortality at 12 months was registered, as the perioperative NLR values. RESULTS: After hip surgery in the 247 patients (women 71%, median age 85 years, range: 66-102), the mortality was 27.2% [95%confidence interval (CI): 21.4-33.0] at 12 months. Univariate analysis detected four risk factors for mortality: age (Hazard Ratio (HR)--by 10 year-increments: 2.08 [95%CI: 1.37-3.17], P<0.001), male gender (HR: 1.92 [95%CI: 1.17-3.14], P=0.009, MCM (≥3) (HR: 1.71 [95%CI: 1.006-2.92], P=0.047 and NLR>5 at day 5 (HR: 1.8 [95%CI: 1.11-2.94], P=0.002). In multivariate analysis, two factors remained significantly associated with mortality: age (HR: 2.28 [95%CI: 1.49-3.47], P<0.001) and male gender (HR: 2.26 [95%CI: 1.38-3.72], P=0.001). Two independent risk factors of postoperative cardiovascular complications were identified: NLR>5 at day 5 (Odds Ratio (OR): 3.34 [95%CI: 2.33-4.80], P=0.001) and MCM (OR: 3.04 [95%CI: 2.16-4.29], P=0.006). A higher risk of infection was independently associated with a NLR>5 at day 5 (OR: 2.12 [95%CI: 1.44-3.11], P=0.02). CONCLUSIONS: The NLR at fifth postoperative day is a risk factor of postoperative mortality and cardiovascular complications.

Public media communications about H1N1, risk perceptions and immunization behaviours: A Quebec-France comparison.

During the H1N1 pandemic, governments tailored their communications plans in order to influence risk perception and promote public compliance with the public health plan measures. Considering the volume and the content of calls to flu information centres as indicators of the public risk perception, this mixed method study compares the relation between public communications, risk perception and immunization behaviour in Quebec and France. Results suggest that advocating for clear information and coordination between health authorities and the media promotes adherence to preventive behaviour. However, over-exaggerating the risks and minimizing the population's agency may undermine health authority credibility.

The relationship between mental disorders and types of crime in inmates in a Brazilian prison.

This cross-sectional study conducted in prisons in the city of Salvador, Bahia, Brazil, investigated the association between the presence of psychiatric disorders in 462 prisoners and the types of crimes committed by them. Psychiatric diagnosis was obtained by means of the Brazilian Portuguese version of the Mini-International Neuropsychiatric Interview. A statistically significant association was found between some psychiatric disorders and specific groups of crime: lifelong substance addiction with sex crimes and homicide; antisocial personality disorder with robbery and with kidnapping and extortion; borderline personality disorder with sex crimes; and lifelong alcohol addiction with fraud and conspiracy and with armed robbery and murder. It was concluded that the mental disorders considered more severe (psychosis and bipolar disorder) were not associated with violent crimes, suggesting that the severity of the psychotic disorder may be the factor that has caused psychosis to be associated with violent crimes in previous studies.

Ethnic and religious discrimination: the multifaceted role of religiosity and collective self-esteem.

This study analyses the roles of collective self-esteem and religiosity in the relationship between discrimination and psychological distress among a sample of 432 recent immigrants from Haiti and Arab countries living in Montreal, Quebec. Collective self-esteem (CSE), religiosity, discriminatory experiences, and psychological symptoms of depression and anxiety were assessed. Regression analyses revealed direct negative effects of discrimination, CSE, and religiosity on psychological distress for the entire sample. CSE, however, also appeared to moderate the effects of discrimination on psychological distress. Participants with higher CSE reported lower levels of anxiety and depression as a result of discrimination compared to those who expressed lower CSE levels. The results suggest that the relationship between CSE, discrimination, and psychological distress must be reexamined in light of recent sociopolitical changes and the upsurge in ethnic and religious tensions following the war on terror.

Thiazolylaminomannosides as potent antiadhesives of type 1 piliated Escherichia coli isolated from Crohn's disease patients.

Adherent-invasive Escherichia coli (AIEC) have previously been shown to induce gut inflammation in patients with Crohn's disease (CD). We developed a set of mannosides to prevent AIEC attachment to the gut by blocking the FimH bacterial adhesin. The crystal structure of the FimH lectin domain in complex with a lead thiazolylaminomannoside highlighted the preferential position for pharmacomodulations. A small library of analogues showing nanomolar affinity for FimH was then developed. Notably, AIEC attachment to intestinal cells was efficiently prevented by the most active compound and at around 10000-fold and 100-fold lower concentrations than mannose and the potent FimH inhibitor heptylmannoside, respectively. An ex vivo assay performed on the colonic tissue of a transgenic mouse model of CD confirmed this antiadhesive potential. Given the key role of AIEC in the chronic intestinal inflammation of CD patients, these results suggest a potential antiadhesive treatment with the FimH inhibitors developed.

Pursuit of a 'normal life': mood, anxiety, and their disordering.

Throughout the process of being treated for mood and anxiety disorders, people dream of the "normal life" that awaits them. However, post-therapy, the distinctiveness of clinical normality (i.e., reduced symptomatology) and social normativity become more apparent. In this article we suggest that for people who have long felt socially excluded because of their psychiatric symptoms, being "normally shy" or "normally awkward" is not enough. Instead they aspire to an ideal life. This confusion between means and ends, between a nonsymptomatic self, a normative self, and an ideal self, leads these individuals to long-term self-doubt and confusion about how to reach their elusive goals. Yet, their never-ending pursuit of normative ideals applies to "normal" and "abnormal" people alike. An analysis of narratives of exclusion allows us to reflect the life-long search for social inclusion via a normal life.

Surface properties and cell adhesion onto allylamine-plasma and amine-plasma coated glass coverslips.

Surface properties of nanoparticles to be used for radioimmunotherapy need to be optimized to allow antibody conjugation while ensuring biocompatibility. We aimed to investigate cell adhesion and proliferation onto different coatings to be used for nanoparticles. C, CH(x) or SiO(x) coatings deposited onto glass coverslips by magnetron deposition as well as nitrogen functionalized materials synthetized using different reactive sputtering conditions and PPAA (plasma polymerized allylamine) coating, were compared. Amine functionalization did increase hydrophilicity in all the materials tested. Biocompatibility was assessed by measuring cell viability, morphology, attachment, spreading, and pro-inflammatory cytokine secretion. The results show that C and CN(x) were the most biocompatible substrates while SiO(x) and SiO(x)N(y) were the most toxic materials. PPAA coatings displayed unexpectedly an intermediate biocompatibility. A correlation could be observed between wettability and cell proliferation except for C coated surface, indicating that more complex processes than hydrophilicity alone are taking place that affect cell functions.

Perceived discrimination and its association with psychological distress among newly arrived immigrants before and after September 11, 2001.

OBJECTIVES: We compared the evolution of perception of discrimination from 1998 to 2007 among recent Arab (Muslim and non-Muslim) and Haitian immigrants to Montreal; we also studied the association between perception of discrimination and psychological distress in 1998 and 2007. METHODS: We conducted this cross-sectional comparative research with 2 samples: one recruited in 1998 (n = 784) and the other in 2007 (n = 432). The samples were randomly extracted from the registry of the Ministry of Immigration and Cultural Communities of Quebec. Psychological distress was measured with the Hopkins Symptom Checklist-25. RESULTS: The perception of discrimination increased from 1998 to 2007 among the Arab Muslim, Arab non-Muslim, and Haitian groups. Muslim Arabs experienced a significant increase in psychological distress associated with discrimination from 1998 to 2007. CONCLUSIONS: These results confirm an increase in perception of discrimination and psychological distress among Arab Muslim recent immigrant communities after September 11, 2001, and highlight the importance this context may have for other immigrant groups.

Perception that "everything requires a lot of effort": transcultural SCL-25 item validation.

This brief report illustrates how the migration context can affect specific item validity of mental health measures. The SCL-25 was administered to 432 recently settled immigrants (220 Haitian and 212 Arabs). We performed descriptive analyses, as well as Infit and Outfit statistics analyses using WINSTEPS Rasch Measurement Software based on Item Response Theory. The participants' comments about the item You feel everything requires a lot of effort in the SCL-25 were also qualitatively analyzed. Results revealed that the item You feel everything requires a lot of effort is an outlier and does not adjust in an expected and valid fashion with its cluster items, as it is over-endorsed by Haitian and Arab healthy participants. Our study thus shows that, in transcultural mental health research, the cultural and migratory contexts may interact and significantly influence the meaning of some symptom items and consequently, the validity of symptom scales.
