Background: Evidence shows that there is a high prevalence of mental health challenges including depression and anxiety, among Chinese university students. Providing mental health care providers with professional training is crucial to implementing effective mental health promotion initiatives in university settings. Globally, the focus of the mental health system is shifting to recovery and the importance of empowerment is increasingly being emphasized. There is a call to integrate empowerment education into professional training programs for health service providers with the goal of mobilizing them to become mental health champions capable of advancing mental health care. Method: The ACE-LYNX (Acceptance and Commitment to Empowerment-Linking Youth and Xin i.e., "heart(s)" in Chinese) intervention took place at six universities in Jinan, Shandong Province, China. It aimed to promote mental health literacy and build capacity among mental health service providers (MHSPs) to enable them to become mental health champions at their universities and beyond. A total of 139 university MHSPs participated. We collected pre-, immediate post- and three-month-post-surveys. In addition, we recruited forty-five participants to take part in three-month-post-intervention focus group interviews to explore their experiences taking part in ACE-LYNX and applying the knowledge, skills, and insights they gained from the intervention. Result: This paper reports on the effects of empowerment education, which is a key component of ACE-LYNX, on the MHSPs. Four themes were identified: 1) conscious awareness and behavioral change through psychological empowerment users; 2) professional insights and motivation for organizational empowerment; 3) non-self in the continuum of collective empowerment; and 4) interdisciplinary challenges and divergences in empowerment action. Discussion: We found that it is critical to integrate empowerment education into professional training. The process of MHSPs developing their empowerment practice is characterized by their moving from individual to collective empowerment along a continuum, with organizational and collective empowerment taking place in a longer time frame. Experiential learning, empathy education, and critical reflection accelerated the continuous iterative transformative process of empowerment practices. To advance the integration of empowerment into mental health care, the engagement of organizational decision-makers and policy makers in empowerment training is critical to ensure alignment of empowerment values and competence at all levels of service provision.

Due to cultural and systemic factors, Chinese-Canadians tend to use mental health services less or when mental health problems are more severe. Services need to be more culturally responsive in their treatment of mental illness. Around important life events, when there may be heightened vulnerability to mental illness, this is especially important. In this study, postpartum cultural practices were examined among recent immigrant, longer-term immigrant, and Canadian-born Chinese women. We conducted a longitudinal cohort study of 493 women in Toronto, Ontario, with livebirths in 2011–2014. Participants completed a demographic survey and Postpartum Rituals Questionnaire. Most women (82.2%) practiced at least one postpartum ritual. Younger age (OR 0.93; 95% CI 0.87–0.99) and greater participation in the heritage culture (OR 1.28; 95% CI 1.02–1.61) were associated with ritual practice. From among five types of postpartum rituals identified (i.e., avoidance of homeostatic disturbances, dietary practices, wind avoidance, organized support, and cold avoidance), dietary practices were most commonly undertaken and cold avoidance was least commonly undertaken. There were differences in postpartum ritual patterns by immigration status, with immigrant women being more likely to undertake a greater number of rituals, to attribute these rituals to Chinese culture, and to ascribe health benefits to these rituals and being less likely to feel forced into performing these rituals. Our findings underscore the importance of clinicians becoming more aware of Chinese postpartum rituals to provide women with culturally competent and patient-centered care. [ABSTRACT FROM AUTHOR]

Emerging research shows that Acceptance and Commitment Therapy (ACT) may improve mental health for caregivers. Parents of autistic children, adolescents, and adults (N = 54) were randomly assigned to either complete a brief group-based ACT intervention or remain on the waitlist. Participants completed surveys immediately prior to randomization, and 3-, 7-, and 17-weeks post-randomization. The primary outcome was depression symptoms and secondary outcomes included stress, goal attainment, positive affect, ACT psychological processes, child mental health, and family functioning. Mixed effects linear models testing Group × Time interaction indicated the Treatment group (n = 27) demonstrated greater post-intervention improvements than the Waitlist group (n = 27) in parent depression (p =.03, d = −0.64) and family distress (p =.04, d = −0.57). Treatment group parents also reported greater short-term gains in positive affect (p =<.001, d = 0.77) and personal goal attainment (p =.007, d = 0.80), compared to the Waitlist group. Although there was no significant Group × Time interaction for other outcomes, stress (b = −2.58, p =.01), defusion (b = −3.78, p =.001), and experiential avoidance (b = −4.22, p =.01) showed improvement for the Treatment group, but not the Waitlist group, at post-intervention. All Treatment group improvements were maintained at follow-up. Results suggest that a brief ACT group intervention is efficacious for improving some aspects of mental health for parents of autistic children. Parents of autistic children commonly experience difficulties with their own mental health. This study looked at the effects of a brief group-based Acceptance and Commitment Therapy program, developed for parents of autistic children, youth, and adults. ACT focuses on increasing psychological flexibility, which is the ability to be mindful and accepting of difficult thoughts and experiences, shown to be important for mental wellness. Participants included 54 parents of autistic people, ages 3–34. Parents were randomly divided into two groups: a Treatment group that received the intervention right away, and a Waitlist group that completed the program after the Treatment group completed the trial. All parents filled out questionnaires right before the program began, and at 3, 7, and 17 weeks after randomization. Compared to the group that was waiting to participate in the program, parents in the Treatment group reported greater improvements in depression and family distress, and these improvements were still present 4 months later. Parents in the Treatment group also reported short-term improvements in their positive feelings and personal goals, compared to those waiting. Results showed that ACT may help improve some aspects of mental health for parents of autistic children, but further research is recommended. [ABSTRACT FROM AUTHOR]

The knowledge and experience of diverse psychiatrists is crucial to improving care for racialized patients and working toward broader change in health-care institutions and systems.[106],[163],[183] In the meantime, health-care institutions and professional organizations must stop current "colourblind" approaches that are common and continue to perpetuate discrimination against people of colour.[184] One important step would be for each academic department of psychiatry in Canada to identify an equity, diversity and inclusion (EDI) leader. In Canada, where Indigenous Peoples[116] and many other groups are under-represented in the health professions, funding and hiring strategies that lead to recruitment of minority medical students and residents can contribute to a long range shift within psychiatry toward greater diversity and inclusiveness in the mental health workforce and equitable representation of racialized groups.[181],[182] More than mere numerical representation, racialized psychiatrists and trainees need the mental health system to change to become actively anti-racist and welcoming of diversity.

This article provides a commentary on a study conducted in Wuhan City, China, which examined the factors influencing professional help-seeking intention for depression among community-dwelling populations. The study found that positive attitudes towards seeking professional help and knowledge about depression were associated with a higher likelihood of seeking help, while stigma was associated with a lower likelihood. The study emphasized the importance of considering cultural factors, such as the impact of stigma on different cultural beliefs and values, including Confucianism. The commentary also discussed the significance of internalized stigma, the impact of stigma on families, and the influence of social identities on help-seeking behaviors. The article highlights the ongoing issue of stigma surrounding mental illness and the need to address cultural factors to reduce stigma and promote mental health. It emphasizes the importance of a knowledge-based approach that incorporates cultural perspectives and appropriate research methodologies. The text also suggests the importance of conducting research on treatments that combine Western approaches with traditional practices, particularly for the Asian population, in order to expand our understanding of mental health and illness. The overall goal is to foster greater compassion, acceptance, and cultural competence in the field of mental health. [Extracted from the article]

Caregivers of autistic children and caregivers of children with fetal alcohol spectrum disorder (FASD) experience considerable stress. However, what is unique or similar across these groups remains understudied. This study explored how female caregivers of children with FASD who registered to participate in a caregiver focused mental health intervention differed from female caregivers of autistic children participating in a similar intervention. Prior to the intervention, caregivers of children with FASD (n = 21), and caregivers of autistic children (n = 22) were asked to complete an online baseline questionnaire. This questionnaire collected information pertaining to caregiver and child demographics, as well as clinical characteristics related to wellbeing, values, and what caregivers identified as rewarding and challenging about raising their child. Results identified similarities across caregiver groups in terms of wellbeing, values, and the challenges and rewards they identified with raising their children. Given the similarities in these two caregiver groups, and the shortage of research on families of people with FASD relative to families of autistic people, interventions for family caregivers in the autism community may also be applicable for FASD families, for whom fewer resources are available.

The current paper examines whether resilience-promoting interventions lead to increased self-reported resilience relative to a control group. The literature search was conducted using terms "resilience intervention" OR "promoting resilience" OR "promoting resiliency" OR "resilience-based intervention". A total of 83 studies were included in the meta-analysis and systematic review. The quality of studies was evaluated based on sample size, appropriateness of statistical analyses, and protocol for intervention adoption. Moderation models examined effects of study characteristics (study rigour), delivery characteristics (mode of intervention [e.g., self-guided], mode of delivery [e.g., in-person] and format [e.g., group-based]), and resilience characteristics (type of resilience [e.g., coping] and resilience process) on outcomes. Findings indicated that resilience-promoting interventions significantly improved resilience relative to controls, Hedges' g = 0.72 (SE = 0.07, 95% CI = [0.59, 0.85], Z = 10.61, p <.001). These effects were heterogeneous, Q(102) = 1232.57, p <.001. Mode of intervention, resilience type, and resilience process emerged as important moderators. Results of the current meta-analysis support the effectiveness of resilience interventions, while positing considerations for intervention design and implementation. Clinical and research implications are discussed. [ABSTRACT FROM AUTHOR]

Stigma of mental illness contributes to silence, denial and delayed help seeking. Existing stigma reduction strategies seldom consider gender and cultural contexts. The Strengths in Unity study was a multi-site Canadian study that engaged Asian men in three stigma reduction interventions (ACT, CEE, psychoeducation) and mobilized them as Community Mental Health Ambassadors. Our participants included both men living with or affected by mental illness (LWA) as well as community leaders (CL). This paper will: (1) describe the baseline characteristics of the Toronto participants including their sociodemographic information, mental illness stigma (CAMI and ISMI), attitudes towards social change (SJS), and intervention-related process variables (AAQ-II, VLQ, FMI, Empowerment); (2) compare the differences among these variables between LWA and CL; and (3) explore factors that may correlate with socio-economic status and mental health stigma. A total of 609 Asian men were recruited in Toronto, Canada. Both CL and LWA had similar scores on measures of external and internalized stigma and social change attitudes, except that LWA had more positive views about the acceptance and integration of those with mental illness into the community on the CAMI, while CL had a higher level of perceived behavioral control on the SJS. Group differences were also observed between LWA and CL in some process-related variables. Exploratory analysis suggests that younger and more educated participants had lower stigma. Our findings underscore the importance of engaging both community leaders and people with lived experience as mental health advocates to address stigma. [ABSTRACT FROM AUTHOR]

Background: During a global pandemic, it is critical to rapidly deploy a psychological intervention to support the mental health and resilience of highly affected individuals and communities. Objective: This is the rationale behind the development and implementation of the Pandemic Acceptance and Commitment to Empowerment Response (PACER) Training, an online, blended, skills building intervention to increase the resilience and well-being of participants while promoting their individual and collective empowerment and capacity building. Methods: Based on acceptance and commitment therapy (ACT) and social justice–based group empowerment psychoeducation (GEP), we developed the Acceptance and Commitment to Empowerment (ACE) model to enhance psychological resilience and collective empowerment. The PACER program consists of 6 online, interactive, self-guided modules complemented by 6 weekly, 90-minute, videoconference, facilitator-led, group sessions. Results: As of August 2021, a total of 325 participants had enrolled in the PACER program. Participants include frontline health care providers and Chinese-Canadian community members. Conclusions: The PACER program is an innovative intervention program with the potential for increasing resilience and empowerment while reducing mental distress during the pandemic.

Aims Data regarding the effects of regular alcohol consumption on cardiac anatomy and function are scarce. Therefore, we sought to determine the relationship between regular alcohol intake and cardiac structure and function as evaluated with cardiac magnetic resonance imaging. Methods and results Participants of the UK Biobank who underwent cardiac magnetic resonance were enrolled in our analysis. Data regarding regular alcohol consumption were obtained from questionnaires filled in by the study participants. Exclusion criteria were poor image quality, missing, or incongruent data regarding alcohol drinking habits, prior drinking, presence of heart failure or angina, and prior myocardial infarction or stroke. Overall, 4335 participants (61.5 ± 7.5 years, 47.6% male) were analysed. We used multivariate linear regression models adjusted for age, ethnicity, body mass index, smoking, hypertension, diabetes mellitus, physical activity, cholesterol level, and Townsend deprivation index to examine the relationship between regular alcohol intake and cardiac structure and function. In men, alcohol intake was independently associated with marginally increased left ventricular end-diastolic volume [ β  = 0.14; 95% confidence interval (CI) = 0.05–0.24; P  = 0.004], left ventricular stroke volume (β  = 0.08; 95% CI = 0.03–0.14; P  = 0.005), and right ventricular stroke volume (β  = 0.08; 95% CI = 0.02–0.13; P  = 0.006). In women, alcohol consumption was associated with increased left atrium volume (β  = 0.14; 95% CI = 0.04–0.23; P  = 0.006). Conclusion Alcohol consumption is independently associated with a marginal increase in left and right ventricular volumes in men, but not in women, whereas alcohol intake showed an association with increased left atrium volume in women. Our results suggest that there is only minimal relationship between regular alcohol consumption and cardiac morphology and function in an asymptomatic middle-aged population. [ABSTRACT FROM AUTHOR]

A position statement developed by the Canadian Psychiatric Association (CPA) on racism and social justice in mental health is presented. It calls for social change to address violence and inequities of systemic racism and discrimination around the world. It also calls for diversity in mental health professional training, the creation of inclusive and safe educational and clinical environment, and challenging biases and assumptions built into mental health theory and practice.

Background and Objectives: Obstructive sleep apnea (OSA) is a common disorder with an increased risk for left ventricular and right ventricular dysfunction. Most studies to date have examined populations with manifest cardiovascular disease using echocardiography to analyze ventricular dysfunction with little or no reference to ventricular volumes or myocardial mass. Our aim was to explore these parameters with cardiac MRI. We hypothesized that there would be stepwise increase in left ventricular mass and right ventricular volumes from the unaffected, to the snoring and the OSA group. Materials and Methods: We analyzed cardiac MRI data from 4978 UK Biobank participants free from cardiovascular disease. Participants were allocated into three cohorts: with OSA, with self-reported snoring and without OSA or snoring (n = 118, 1886 and 2477). We analyzed cardiac parameters from balanced cine-SSFP sequences and indexed them to body surface area. Results: Patients with OSA were mostly males (47.3% vs. 79.7%; p < 0.001) with higher body mass index (25.7 ± 4.0 vs. 31.3 ± 5.3 kg/m²; p < 0.001) and higher blood pressure (135 ± 18 vs. 140 ± 17 mmHg; p = 0.012) compared to individuals without OSA or snoring. Regression analysis showed a significant effect for OSA in left ventricular end-diastolic index (LVEDVI) (β = −4.9 ± 2.4 mL/m²; p = 0.040) and right ventricular end-diastolic index (RVEDVI) (β = −6.2 ± 2.6 mL/m²; p = 0.016) in females and for right ventricular ejection fraction (RVEF) (β = 1.7 ± 0.8%; p = 0.031) in males. A significant effect was discovered in snoring females for left ventricular mass index (LVMI) (β = 3.5 ± 0.9 g/m²; p < 0.001) and in males for left ventricular ejection fraction (LVEF) (β = 1.0 ± 0.3%; p = 0.001) and RVEF (β = 1.2 ± 0.3%; p < 0.001). Conclusion: Our study suggests that OSA is highly underdiagnosed and that it is an evolving process with gender specific progression. Females with OSA show significantly lower ventricular volumes while males with snoring show increased ejection fractions which may be an early sign of hypertrophy. Separate prospective studies are needed to further explore the direction of causality. [ABSTRACT FROM AUTHOR]

Mental illness stigma has detrimental effects on health and wellbeing. Approaches to address stigma in racialized populations in Western nations need to emphasize inclusivity, social justice, and sociocultural intersectionality of determinants of health. The current paper evaluates three intervention approaches to reduce stigma of mental illness among Asian men in Toronto, Canada. Participants received one of four group interventions: psychoeducation, Acceptance and Commitment Therapy (ACT), Contact-based Empowerment Education (CEE), and a combination of ACT+CEE. Self-report measures on stigma (CAMI, ISMI) and social change (SJS) were administered before and after the intervention. A total of 535 Asian men completed the interventions. Overall analyses found that all intervention approaches were successful in reducing stigma and promoting social change. Subscale differences suggest that CEE may be more broadly effective in reducing mental illness stigmatizing attitudes while ACT may be more specifically effective in reducing internalized stigma. More work needs to be done to elucidate mechanisms that contribute to socioculturally-informed mental illness stigma interventions for racialized communities and traditionally marginalized populations.

Background: Coronavirus disease 2019 (COVID-19) disproportionately affects older people. Observational studies suggest indolent cardiovascular involvement after recovery from acute COVID-19. However, these findings may reflect pre-existing cardiac phenotypes. Aims: We tested the association of baseline cardiovascular magnetic resonance (CMR) phenotypes with incident COVID-19. Methods: We studied UK Biobank participants with CMR imaging and COVID-19 testing. We considered left and right ventricular (LV, RV) volumes, ejection fractions, and stroke volumes, LV mass, LV strain, native T1, aortic distensibility, and arterial stiffness index. COVID-19 test results were obtained from Public Health England. Co-morbidities were ascertained from self-report and hospital episode statistics (HES). Critical care admission and death were from HES and death register records. We investigated the association of each cardiovascular measure with COVID-19 test result in multivariable logistic regression models adjusting for age, sex, ethnicity, deprivation, body mass index, smoking, diabetes, hypertension, high cholesterol, and prior myocardial infarction. Results: We studied 310 participants (n = 70 positive). Median age was 63.8 [57.5, 72.1] years; 51.0% (n = 158) were male. 78.7% (n = 244) were tested in hospital, 3.5% (n = 11) required critical care admission, and 6.1% (n = 19) died. In fully adjusted models, smaller LV/RV end-diastolic volumes, smaller LV stroke volume, and poorer global longitudinal strain were associated with significantly higher odds of COVID-19 positivity. Discussion: We demonstrate association of pre-existing adverse CMR phenotypes with greater odds of COVID-19 positivity independent of classical cardiovascular risk factors. Conclusions: Observational reports of cardiovascular involvement after COVID-19 may, at least partly, reflect pre-existing cardiac status rather than COVID-19 induced alterations.

Osteoporosis and ischemic heart disease (IHD) represent important public health problems. Existing research suggests an association between the two conditions beyond that attributable to shared risk factors, with a potentially causal relationship. In this study, we tested the association of bone speed of sound (SOS) from quantitative heel ultrasound with (i) measures of arterial compliance from cardiovascular magnetic resonance (aortic distensibility [AD]); (ii) finger photoplethysmography (arterial stiffness index [ASI]); and (iii) incident myocardial infarction and IHD mortality in the UK Biobank cohort. We considered the potential mediating effect of a range of blood biomarkers and cardiometabolic morbidities and evaluated differential relationships by sex, menopause status, smoking, diabetes, and obesity. Furthermore, we considered whether associations with arterial compliance explained association of SOS with ischemic cardiovascular outcomes. Higher SOS was associated with lower arterial compliance by both ASI and AD for both men and women. The relationship was most consistent with ASI, likely relating to larger sample size available for this variable (n = 159,542 versus n = 18,229). There was no clear evidence of differential relationship by menopause, smoking, diabetes, or body mass index (BMI). Blood biomarkers appeared important in mediating the association for both men and women, but with different directions of effect and did not fully explain the observed effects. In fully adjusted models, higher SOS was associated with significantly lower IHD mortality in men, but less robustly in women. The association of SOS with ASI did not explain this observation. In conclusion, our findings support a positive association between bone and vascular health with consistent patterns of association in men and women. The underlying mechanisms are complex and appear to vary by sex. © 2020 The Authors.

Background: Mitral valve (MV) and tricuspid valve (TV) apparatus geometry are essential to define mechanisms and etiologies of regurgitation and to inform surgical or transcatheter interventions. Given the increasing use of cardiovascular magnetic resonance (CMR) for the evaluation of valvular heart disease, we aimed to establish CMR-derived age- and sex-specific reference values for mitral annular (MA) and tricuspid annular (TA) dimensions and tethering indices derived from truly healthy Caucasian adults.Methods: 5065 consecutive UK Biobank participants underwent CMR using cine balanced steady-state free precession imaging at 1.5 T. Participants with non-Caucasian ethnicity, prevalent cardiovascular disease and other conditions known to affect cardiac chamber size and function were excluded. Absolute and indexed reference ranges for MA and TA diameters and tethering indices were stratified by gender and age (45–54, 55–64, 65–74 years).Results: Overall, 721 (14.2%) truly healthy participants aged 45–74 years (54% women) formed the reference cohort. Absolute MA and TA diameters, MV tenting length and MV tenting area, were significantly larger in men. Mean ± standard deviation (SD) end-diastolic and end-systolic MA diameters in the 3-chamber view (anteroposterior diameter) were 2.9 ± 0.4 cm (1.5 ± 0.2 cm/m2) and 3.3 ± 0.4 cm (1.7 ± 0.2 cm/m2) in men, and 2.6 ± 0.4 cm (1.6 ± 0.2 cm/m2) and 3.0 ± 0.4 cm (1.8 ± 0.2 cm/m2) in women, respectively. Mean ± SD end-diastolic and end-systolic TA diameters in the 4-chamber view were 3.2 ± 0.5 cm (1.6 ± 0.3 cm/m2) and 3.2 ± 0.5 cm (1.7 ± 0.3 cm/m2) in men, and 2.9 ± 0.4 cm (1.7 ± 0.2 cm/m2) and 2.8 ± 0.4 cm (1.7 ± 0.3 cm/m2) in women, respectively. With advancing age, end-diastolic TA diameter became larger and posterior MV leaflet angle smaller in both sexes. Reproducibility of measurements was good to excellent with an inter-rater intraclass correlation coefficient (ICC) between 0.92 and 0.98 and an intra-rater ICC between 0.90 and 0.97.Conclusions: We described age- and sex-specific reference ranges of MA and TA dimensions and tethering indices in the largest validated healthy Caucasian population. Reference ranges presented in this study may help to improve the distinction between normal and pathological states, prompting the identification of subjects that may benefit from advanced cardiac imaging for annular sizing and planning of valvular interventions.

Aims  The non-invasive assessment of left ventricular (LV) diastolic function and filling pressure in hypertrophic cardiomyopathy (HCM) is still an open issue. Pulmonary blood volume index (PBVI) by cardiovascular magnetic resonance (CMR) has been proposed as a quantitative biomarker of haemodynamic congestion. We aimed to assess the diagnostic accuracy of PBVI for left atrial pressure (LAP) estimation in patients with HCM. Methods and results  We retrospectively identified 69 consecutive HCM outpatients (age 58 ± 11 years; 83% men) who underwent both transthoracic echocardiography (TTE) and CMR. Guideline-based detection of LV diastolic dysfunction was assessed by TTE, blinded to CMR results. PBVI was calculated as the product of right ventricular stroke volume index and the number of cardiac cycles for a bolus of gadolinium to pass through the pulmonary circulation as assessed by first-pass perfusion imaging. Compared to patients with normal LAP, patients with increased LAP showed significantly larger PBVI (463 ± 127 vs. 310 ± 86 mL/m2, P  < 0.001). PBVI increased progressively with worsening New York Heart Association functional class and echocardiographic stages of diastolic dysfunction (P  < 0.001 for both). At the best cut-off point of 413 mL/m2, PBVI yielded good diagnostic accuracy for the diagnosis of LV diastolic dysfunction with increased LAP [C-statistic = 0.83; 95% confidence interval (CI): 0.73–0.94]. At multivariable logistic regression analysis, PBVI was an independent predictor of increased LAP (odds ratio per 10% increase: 1.97, 95% CI: 1.06–3.68; P  = 0.03). Conclusion  PBVI is a promising CMR application for assessment of diastolic function and LAP in patients with HCM and may serve as a quantitative marker for detection, grading, and monitoring of haemodynamic congestion.

Objective: Vigorous physical activity (PA) in highly trained athletes has been associated with heightened left ventricular (LV) trabeculation extent. It has therefore been hypothesised that LV trabeculation extent may participate in exercise-induced physiological cardiac remodelling. Our cross-sectional observational study aimed to ascertain whether there is a 'dose-response' relationship between PA and LV trabeculation extent and whether this could be identified at opposite PA extremes.Methods: In a cohort of 1030 individuals from the community-based UK Biobank study (male/female ratio: 0.84, mean age: 61 years), PA was measured via total metabolic equivalent of task (MET) min/week and 7-day average acceleration, and trabeculation extent via maximal non-compaction/compaction ratio (NC/C) in long-axis images of cardiovascular magnetic resonance studies. The relationship between PA and NC/C was assessed by multivariate regression (adjusting for potential confounders) as well as between demographic, anthropometric and LV phenotypic parameters and NC/C.Results: There was no significant linear relationship between PA and NC/C (full adjustment, total MET-min/week: ß=-0.0008, 95% CI -0.039 to -0.037, p=0.97; 7-day average acceleration: ß=-0.047, 95% CI -0.110 to -0.115, p=0.13, per IQR increment in PA), or between extreme PA quintiles (full adjustment, total MET-min/week: ß=-0.026, 95% CI -0.146 to -0.094, p=0.67; 7-day average acceleration: ß=-0.129, 95% CI -0.299 to -0.040, p=0.49), across all adjustment levels. A negative relationship was identified between left ventricular ejection fraction and NC/C, significantly modified by PA (ß difference=-0.006, p=0.03).Conclusions: In a community-based general population cohort, there was no relationship at, or between, extremes, between PA and NC/C, suggesting that at typical general population PA levels, trabeculation extent is not influenced by PA changes.

Introduction: Aortic distensibility can be calculated using semi-automated methods to segment the aortic lumen on cine CMR (Cardiovascular Magnetic Resonance) images. However, these methods require visual quality control and manual localization of the region of interest (ROI) of ascending (AA) and proximal descending (PDA) aorta, which limit the analysis in large-scale population-based studies. Using 5100 scans from UK Biobank, this study sought to develop and validate a fully automated method to 1) detect and locate the ROIs of AA and PDA, and 2) provide a quality control mechanism. Methods: The automated AA and PDA detection-localization algorithm followed these steps: 1) foreground segmentation; 2) detection of candidate ROIs by Circular Hough Transform (CHT); 3) spatial, histogram and shape feature extraction for candidate ROIs; 4) AA and PDA detection using Random Forest (RF); 5) quality control based on RF detection probability. To provide the ground truth, overall image quality (IQ = 0–3 from poor to good) and aortic locations were visually assessed by 13 observers. The automated algorithm was trained on 1200 scans and Dice Similarity Coefficient (DSC) was used to calculate the agreement between ground truth and automatically detected ROIs. Results: The automated algorithm was tested on 3900 scans. Detection accuracy was 99.4% for AA and 99.8% for PDA. Aorta localization showed excellent agreement with the ground truth, with DSC ≥ 0.9 in 94.8% of AA (DSC = 0.97 ± 0.04) and 99.5% of PDA cases (DSC = 0.98 ± 0.03). AA×PDA detection probabilities could discriminate scans with IQ ≥ 1 from those severely corrupted by artefacts (AUC = 90.6%). If scans with detection probability < 0.75 were excluded (350 scans), the algorithm was able to correctly detect and localize AA and PDA in all the remaining 3550 scans (100% accuracy). Conclusion: The proposed method for automated AA and PDA localization was extremely accurate and the automatically derived detection probabilities provided a robust mechanism to detect low quality scans for further human review. Applying the proposed localization and quality control techniques promises at least a ten-fold reduction in human involvement without sacrificing any accuracy. [ABSTRACT FROM AUTHOR]

Mothers of children with autism spectrum disorder (ASD) often face high levels of stress. While there have been interventions for parents of children with ASD targeting their parenting skills, there have been fewer studies that aim to target the psychological or physical well-being of the mothers themselves. This study included mothers of children with ASD to cofacilitate acceptance and commitment therapy (ACT) to other mothers of children with ASD. The intervention consisted of one evening session and a full-day workshop, followed by a refresher session 1 month later. Of the 33 mothers that enrolled in the study, 29 attended all three sessions and completed the outcome measures. Significant changes were observed over time in terms of depression, stress, social isolation and physical health scores. Post hoc analyses showed reductions in stress and depression and improvements in physical health which were maintained at follow-up. Results suggest that a brief parent-facilitated ACT group intervention may be effective in improving the mental and physical health of mothers of children with ASD. [ABSTRACT FROM AUTHOR]

Few studies have examined interventions or therapeutic processes that may help parents of children with Autism Spectrum Disorder (ASD) manage their stress. This study examines the impact of a brief Acceptance and Commitment Therapy (ACT) group intervention, led by parents, among a cohort of 33 mothers of children with ASD. Changes in ACT process measures (psychological flexibility, cognitive fusion, values) were evaluated at pre, post, and 3 months following the intervention. Mothers reported significant improvement post-intervention in psychological flexibility, cognitive fusion, and value-consistent activities in multiple life domains, including parenting, relationships, and self-care. These improvements were maintained at follow-up. The results provide preliminary evidence that improvements observed in depression and stress may be mediated by cognitive fusion and action-values consistency. [ABSTRACT FROM AUTHOR]

Racialized diasporic communities in Canada experience disproportionate burden of HIV infection. Their increased vulnerabilities are associated with interlocking challenges, including barriers in accessing resources, migration and settlement stress, and systemic exclusion. Further, people living with HIV (PLHIV) in these diasporic communities face stigma and discrimination in both mainstream Canadian society as well as their own ethno-racial communities. HIV stigma negatively impacts all aspects of HIV care, from testing to disclosure to treatment and ongoing care. In response to these challenges, a Toronto based community organization developed and implemented the CHAMP project to engage people living with HIV/AIDS (PLHIV) and leaders from different service sectors from the African/Caribbean, Asian and Latino communities to explore challenges and strategies to reduce HIV stigma and build community resilience. The study engaged 66 PLHIV and ethno-racial leaders from faith, media and social justice sectors in two stigma-reduction training programs: Acceptance Commitment Therapy Training (ACT) and Social Justice Capacity Building (SJCB). Data collection included pre-and post- intervention surveys, focus groups and monthly activity logs. Participants were followed for a year and data on changes in the participants’ attitudes and behaviors as well as their actual engagement in HIV prevention, PLHIV support and stigma reduction activities were collected. CHAMP results showed that the interventions were effective in reducing HIV stigma and increasing participants’ readiness to take action towards positive social change. Participants’ activity logs over a period of 9 months after completing the training showed they had engaged in 1090 championship activities to advocate for HIV related health equity and social justice issues affecting racialized and newcomer PLHIV and communities.

Background: We explored understanding and experiences of health advocacy among psychiatry and family medicine residents and faculty and the implications for clinical care and teaching through the lens of relationship-centred care. Methods: This qualitative study was conducted in the psychiatry and family medicine departments at a large urban university. We interviewed 19 faculty members and conducted two focus groups with 18 residents. Semi-structured questions explored the relational meaning of health advocacy, how residents and faculty learned about the role and ethical considerations involved in incorporating advocacy work into clinical practice within a relationship-centred care framework. Results: Four themes emerged from the interviews and focus groups: 1) health advocacy as an extension of the relationship to self; 2) health advocacy and professional boundaries in the physician–patient relationship; 3) health advocacy within a team-based approach; and 4) health advocacy and the physician–community/organization relationship. Participants described implications for practice of the challenges of health advocacy, including perceived institutional risks, professional boundaries and the appropriation of patient voice. Conclusions: Our study provides insights into the relational complexities of the health advocate role in residency curriculum and clinical practice. All participants described health advocacy as a broad spectrum of actions that are guided by relationships among patients, health care professionals and communities. Our analysis revealed that some challenges that participants identified with a health advocacy role could be addressed by anchoring the role within a specific theoretical framework. This would better enable us to create a culture of advocacy in the training and development of physicians. [ABSTRACT FROM AUTHOR]

Background: Reduced lung function is common and associated with increased cardiovascular morbidity and mortality, even in asymptomatic individuals without diagnosed respiratory disease. Previous studies have identified relationships between lung function and cardiovascular structure in individuals with pulmonary disease, but the relationships in those free from diagnosed cardiorespiratory disease have not been fully explored. Methods: UK Biobank is a prospective cohort study of community participants in the United Kingdom. Individuals self-reported demographics and co-morbidities, and a subset underwent cardiovascular magnetic resonance (CMR) imaging and spirometry. CMR images were analysed to derive ventricular volumes and mass. The relationships between CMR-derived measures and spirometry and age were modelled with multivariable linear regression, taking account of the effects of possible confounders. Results: Data were available for 4,975 individuals, and after exclusion of those with pre-existing cardiorespiratory disease and unacceptable spirometry, 1,406 were included in the analyses. In fully-adjusted multivariable linear models lower FEV1 and FVC were associated with smaller left ventricular end-diastolic (−5.21ml per standard deviation (SD) change in FEV1, −5.69ml per SD change in FVC), end-systolic (−2.34ml, −2.56ml) and stroke volumes (−2.85ml, −3.11ml); right ventricular end-diastolic (−5.62ml, −5.84ml), end-systolic (−2.47ml, −2.46ml) and stroke volumes (−3.13ml, −3.36ml); and with lower left ventricular mass (−2.29g, −2.46g). Changes of comparable magnitude and direction were observed per decade increase in age. Conclusions: This study shows that reduced FEV1 and FVC are associated with smaller ventricular volumes and reduced ventricular mass. The changes seen per standard deviation change in FEV1 and FVC are comparable to one decade of ageing. [ABSTRACT FROM AUTHOR]

Background: Handgrip strength, a measure of muscular fitness, is associated with cardiovascular (CV) events and CV mortality but its association with cardiac structure and function is unknown. The goal of this study was to determine if handgrip strength is associated with changes in cardiac structure and function in UK adults. Methods and results: Left ventricular (LV) ejection fraction (EF), end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), mass (M), and mass-to-volume ratio (MVR) were measured in a sample of 4,654 participants of the UK Biobank Study 6.3 ± 1 years after baseline using cardiovascular magnetic resonance (CMR). Handgrip strength was measured at baseline and at the imaging follow-up examination. We determined the association between handgrip strength at baseline as well as its change over time and each of the cardiac outcome parameters. After adjustment, higher level of handgrip strength at baseline was associated with higher LVEDV (difference per SD increase in handgrip strength: 1.3ml, 95% CI 0.1–2.4; p = 0.034), higher LVSV (1.0ml, 0.3–1.8; p = 0.006), lower LVM (-1.0g, -1.8 –-0.3; p = 0.007), and lower LVMVR (-0.013g/ml, -0.018 –-0.007; p<0.001). The association between handgrip strength and LVEDV and LVSV was strongest among younger individuals, while the association with LVM and LVMVR was strongest among older individuals. Conclusions: Better handgrip strength was associated with cardiac structure and function in a pattern indicative of less cardiac hypertrophy and remodeling. These characteristics are known to be associated with a lower risk of cardiovascular events. [ABSTRACT FROM AUTHOR]

Background: The effect of menopausal hormone therapy (MHT)–previously known as hormone replacement therapy–on cardiovascular health remains unclear and controversial. This cross-sectional study examined the impact of MHT on left ventricular (LV) and left atrial (LA) structure and function, alterations in which are markers of subclinical cardiovascular disease, in a population-based cohort. Methods: Post-menopausal women who had never used MHT and those who had used MHT ≥3 years participating in the UK Biobank who had undergone cardiovascular magnetic resonance (CMR) imaging and free of known cardiovascular disease were included. Multivariable linear regression was performed to examine the relationship between cardiac parameters and MHT use ≥3 years. To explore whether MHT use on each of the cardiac outcomes differed by age, multivariable regression models were constructed with a cross-product of age and MHT fitted as an interaction term. Results: Of 1604 post-menopausal women, 513 (32%) had used MHT ≥3 years. In the MHT cohort, median age at menopause was 50 (IQR: 45–52) and median duration of MHT was 8 years. In the non-MHT cohort, median age at menopause was 51 (IQR: 48–53). MHT use was associated with significantly lower LV end-diastolic volume (122.8 ml vs 119.8 ml, effect size = -2.4%, 95% CI: -4.2% to -0.5%; p = 0.013) and LA maximal volume (60.2 ml vs 57.5 ml, effect size = -4.5%, 95% CI: -7.8% to -1.0%; p = 0.012). There was no significant difference in LV mass. MHT use significantly modified the effect between age and CMR parameters; MHT users had greater decrements in LV end-diastolic volume, LV end-systolic volume and LA maximal volume with advancing age. Conclusions: MHT use was not associated with adverse, subclinical changes in cardiac structure and function. Indeed, significantly smaller LV and LA chamber volumes were observed which have been linked to favourable cardiovascular outcomes. These findings represent a novel approach to examining MHT’s effect on the cardiovascular system. [ABSTRACT FROM AUTHOR]

UK Biobank, a large cohort study, plans to acquire 100,000 cardiac MRI studies by 2020. Although fully-automated left ventricular (LV) analysis was performed in the original acquisition, this was not designed for unsupervised incorporation into epidemiological studies. We sought to evaluate automated LV mass and volume (Siemens syngo InlineVF versions D13A and E11C), against manual analysis in a substantial sub-cohort of UK Biobank participants. Eight readers from two centers, trained to give consistent results, manually analyzed 4874 UK Biobank cases for LV end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF) and LV mass (LVM). Agreement between manual and InlineVF automated analyses were evaluated using Bland-Altman analysis and the intra-class correlation coefficient (ICC). Tenfold cross-validation was used to establish a linear regression calibration between manual and InlineVF results. InlineVF D13A returned results in 4423 cases, whereas InlineVF E11C returned results in 4775 cases and also reported LVM. Rapid visual assessment of the E11C results found 178 cases (3.7%) with grossly misplaced contours or landmarks. In the remaining 4597 cases, LV function showed good agreement: ESV -6.4 ± 9.0 ml, 0.853 (mean ± SD of the differences, ICC) EDV -3.0 ± 11.6 ml, 0.937; SV 3.4 ± 9.8 ml, 0.855; and EF 3.5 ± 5.1%, 0.586. Although LV mass was consistently overestimated (29.9 ± 17.0 g, 0.534) due to larger epicardial contours on all slices, linear regression could be used to correct the bias and improve accuracy. Automated InlineVF results can be used for case-control studies in UK Biobank, provided visual quality control and linear bias correction are performed. Improvements between InlineVF D13A and InlineVF E11C show the field is rapidly advancing, with further improvements expected in the near future. [ABSTRACT FROM AUTHOR]

Aims: The UK Biobank is a large-scale population-based study utilising cardiovascular magnetic resonance (CMR) to generate measurements of atrial and ventricular structure and function. This study aimed to quantify the association between modifiable cardiovascular risk factors and cardiac morphology and function in individuals without known cardiovascular disease. Methods: Age, sex, ethnicity (non-modifiable) and systolic blood pressure, diastolic blood pressure, smoking status, exercise, body mass index (BMI), high cholesterol, diabetes, alcohol intake (modifiable) were considered important cardiovascular risk factors. Multivariable regression models were built to ascertain the association of risk factors on left ventricular (LV), right ventricular (RV), left atrial (LA) and right atrial (RA) CMR parameters. Results: 4,651 participants were included in the analysis. All modifiable risk factors had significant effects on differing atrial and ventricular parameters. BMI was the modifiable risk factor most consistently associated with subclinical changes to CMR parameters, particularly in relation to higher LV mass (+8.3% per SD [4.3 kg/m2], 95% CI: 7.6 to 8.9%), LV (EDV: +4.8% per SD, 95% CI: 4.2 to 5.4%); ESV: +4.4% per SD, 95% CI: 3.5 to 5.3%), RV (EDV: +5.3% per SD, 95% CI: 4.7 to 5.9%; ESV: +5.4% per SD, 95% CI: 4.5 to 6.4%) and LA maximal (+8.6% per SD, 95% CI: 7.4 to 9.7%) volumes. Increases in SBP were associated with higher LV mass (+6.8% per SD, 95% CI: 5.9 to 7.7%), LV (EDV: +4.5% per SD, 95% CI: 3.6 to 5.4%; ESV: +2.0% per SD, 95% CI: 0.8 to 3.3%) volumes. The presence of diabetes or high cholesterol resulted in smaller volumes and lower ejection fractions. Conclusions: Modifiable risk factors are associated with subclinical alterations in structure and function in all four cardiac chambers. BMI and systolic blood pressure are the most important modifiable risk factors affecting CMR parameters known to be linked to adverse outcomes. [ABSTRACT FROM AUTHOR]

To provide effective psychotherapy in cross-cultural situations, cultural issues need to be adequately addressed. We describe core concepts of cultural competence relevant for psychotherapists to consider. A contextualized approach to conducting cultural competent assessment and formulation is recommended, including the use of DSM-5 Outline for Cultural Formulation and Cultural Formulation Interview. We introduce a cultural competent framework to help therapists become more mindful of culturally relevant interactions in therapy. Finally, a three-tier system is proposed for the examination of psychotherapy models through a cultural lens. The concepts and framework described can be flexibly and pragmatically integrated into a therapist's regular clinical work, increasing the therapy's effectiveness across diverse populations.

Background: Cardiovascular magnetic resonance (CMR) is the gold standard method for the assessment of cardiac structure and function. Reference ranges permit differentiation between normal and pathological states. To date, this study is the largest to provide CMR specific reference ranges for left ventricular, right ventricular, left atrial and right atrial structure and function derived from truly healthy Caucasian adults aged 45-74. Methods: Five thousand sixty-five UK Biobank participants underwent CMR using steady-state free precession imaging at 1.5 Tesla. Manual analysis was performed for all four cardiac chambers. Participants with non-Caucasian ethnicity, known cardiovascular disease and other conditions known to affect cardiac chamber size and function were excluded. Remaining participants formed the healthy reference cohort; reference ranges were calculated and were stratified by gender and age (45-54, 55-64, 65-74). Results: After applying exclusion criteria, 804 (16.²%) participants were available for analysis. Left ventricular (LV) volumes were larger in males compared to females for absolute and indexed values. With advancing age, LV volumes were mostly smaller in both sexes. LV ejection fraction was significantly greater in females compared to males (mean ± standard deviation [SD] of 61 ± 5% vs 58 ± 5%) and remained static with age for both genders. In older age groups, LV mass was lower in men, but remained virtually unchanged in women. LV mass was significantly higher in males compared to females (mean ± SD of 53 ± 9 g/m² vs 4² ± 7 g/m²). Right ventricular (RV) volumes were significantly larger in males compared to females for absolute and indexed values and were smaller with advancing age. RV ejection fraction was higher with increasing age in females only. Left atrial (LA) maximal volume and stroke volume were significantly larger in males compared to females for absolute values but not for indexed values. LA ejection fraction was similar for both sexes. Right atrial (RA) maximal volume was significantly larger in males for both absolute and indexed values, while RA ejection fraction was significantly higher in females. Conclusions: We describe age- and sex-specific reference ranges for the left ventricle, right ventricle and atria in the largest validated normal Caucasian population. [ABSTRACT FROM AUTHOR]

Purpose Racialized minority and newcomer communities are over-represented in positive HIV cases in Canada. Stigma has been identified as one of the barriers to HIV prevention, testing, and treatment. Faith, media, and social justice sectors have historically served a vital role in promoting health issues in these communities. However, they have been relatively inactive in addressing HIV-related issues. The purpose of this paper is to report on the results of an exploratory study that engaged faith, media, and social justice leaders in the African-Caribbean, Asian, and Latino communities in Toronto.Design/methodology/approach This study used a qualitative interpretive design and focus groups to explore the challenges and opportunities in addressing HIV stigma. A total of 23 people living with HIV and 22 community leaders took part in seven focus groups. Intersectionality was used as an analytical lens to examine the social processes that perpetuate HIV stigma.Findings This paper focuses on the perspectives of community leaders. Five themes were identified: misconception of HIV as a gay disease; moralistic religious discourses perpetuate HIV stigma; invisibility of HIV reinforces community denial; need to promote awareness and compassion for people with HIV; and the power of collective community efforts within and across different sectors.Originality/value Although affected communities are faced with many challenges related to HIV stigma, effective change may be possible through concerted efforts championed by people living with HIV and community leaders. One important strategy identified by the participants is to build strategic alliances among the HIV, media, faith, social justice, and other sectors. Such alliances can develop public education and HIV champion activities to promote public awareness and positive emotional connections with HIV issues, challenge HIV stigma and related systems of oppression, and engage young people in HIV championship.
