Exploratory process factor analysis (EPFA) is a data-driven latent variable model for multivariate time series. This article presents analytic standard errors for EPFA. Unlike standard errors for exploratory factor analysis with independent data, the analytic standard errors for EPFA take into account the time dependency in time series data. In addition, factor rotation is treated as the imposition of equality constraints on model parameters. Properties of the analytic standard errors are demonstrated using empirical and simulated data.
Evidence-based insertion and maintenance bundles are effective in reducing the incidence of central line-associated bloodstream infections (CLABSI) in intensive care unit (ICU) settings. We studied the adoption and compliance of CLABSI prevention bundle programs and CLABSI rates in ICUs in a large network of acute care hospitals across Canada.
Coronavirus disease-2019 precipitated the rapid deployment of novel therapeutics, which led to operational and logistical challenges for healthcare organizations. Four health systems participated in a qualitative study to abstract lessons learned, challenges, and promising practices from implementing neutralizing monoclonal antibody (nMAb) treatment programs. Lessons are summarized under three themes that serve as critical building blocks for health systems to rapidly deploy novel therapeutics during a pandemic: (1) clinical workflows, (2) data infrastructure and platforms, and (3) governance and policy. Health systems must be sufficiently agile to quickly scale programs and resources in times of uncertainty. Real-time monitoring of programs, policies, and processes can help support better planning and improve program effectiveness. The lessons and promising practices shared in this study can be applied by health systems for distribution of novel therapeutics beyond nMAbs and toward future pandemics and public health emergencies.
There are no conclusive findings about the possible protective role of religion on students’ mental health during the COVID-19 pandemic. Therefore, more research is needed.
Objectives
The purpose of this study was to assess the relationship between the level of emotional distress and religiosity among students from 7 different countries during the COVID-19 pandemic.
Methods
Data were collected by an online cross-sectional survey that was distributed amongst Polish (N = 1196), Bengali (N = 1537), Indian (N = 483), Mexican (N = 231), Egyptian (N = 565), Philippine (N = 2062), and Pakistani (N = 506) students (N = 6642) from 12th April to 1st June 2021. The respondents were asked several questions regarding their religiosity which was measured by The Duke University Religion Index (DUREL), the emotional distress was measured by the Depression, Anxiety, and Stress Scale-21 (DASS-21).
Results
Egypt with Islam as the dominant religion showed the greatest temple attendance (organizational religious activity: M=5.27±1.36) and spirituality (intrinsic religiosity: M=5.27±1.36), p<0.0001. On another hand, Egyptian students had the lowest emotional distress measured in all categories DASS-21 (depression: M=4.87±10.17, anxiety: M=4.78±10.13, stress: M=20.76±11.46). Two countries with the dominant Christian religion achieved the highest score for private religious activities (non-organizational religious activity; Mexico: M=3.94±0.94, Poland: M=3.63±1.20; p<0.0001) and experienced a moderate level of depressive symptoms, anxiety, and stress. Students from Mexico presented the lowest attendance to church (M=2.46±1,39) and spirituality (M=6.68± 3.41) and had the second highest level of depressive symptoms (M=19.13±13.03) and stress (M=20.27±1.98). Philippines students had the highest DASS-21 score (depression: M=22.77±12.58, anxiety: M=16.07±10.77, stress: M=4.87±10.08) and their level of religiosity reached average values in the whole group. The performed regression analysis confirmed the importance of the 3 dimensions (organizational religious activity, non-organizational religious activity, intrinsic religiosity) of religiosity for the well-being of students, except for the relationship between anxiety and private religious activities. The result was as presented for depression: R2=0.0398, F(3.664)=91.764, p<0.0001, SE of E: 12.88; anxiety: R2=0.0124, F(3.664)=27.683, p<0.0001, SE of E: 10,62; stress: R2= 0.0350, F(3.664)=80.363, p<0.0001, SE of E: 12.30.
Conclusions
The higher commitment to organizational religious activity, non-organizational religious activity, and intrinsic religiositywas correlated with the lower level of depressive symptoms, stress, and anxiety among students during the COVID-19 pandemic, but taking into account factors related to religiosity explains the level of emotional well-being to a small extent.
Peer-support groups for stroke survivors are often organized and facilitated by health authorities and disability related organizations within rehabilitation programs. However, the benefits of peer-led, peer-support groups have not yet been evaluated. The purpose of this study was to explore participants’ experiences in a community-based, peer-led, peer-support group for stroke survivors.
Materials and Methods:
Semi-structured interviews were conducted and analyzed following constructivist grounded theory with 11 participants who attended a peer-led, peer-support group for people with stroke. The data were also complemented with one quantitative rating question regarding their experience attending the group.
Results:
Three themes were identified. Meeting unmet needs after stroke captured how the group was created by stroke survivors to address life in the community post-stroke. Buddies helping buddies highlighted that stroke recovery is a shared process at the group, where members help and encourage each other to contribute what they can. Creating authentic friendships revealed how people experienced social connection and developed relationships in the peer-led, peer-support group.
Conclusions:
Peer-led, peer-support groups may provide opportunities for stroke survivors to connect with like-minded people in their community to have fun while exploring their abilities.
Noonan syndrome is a genetic disorder with high prevalence of congenital heart defects, such as pulmonary stenosis, atrial septal defect and hypertrophic cardiomyopathy. Scarce data exists regarding the safety of pregnancy in patients with Noonan syndrome, particularly in the context of maternal cardiac disease.
Study design:
We performed a retrospective chart review of patients at Yale-New Haven Hospital from 2012 to 2020 with diagnoses of Noonan syndrome and pregnancy. We analysed medical records for pregnancy details and cardiac health, including echocardiograms to quantify maternal cardiac dysfunction through measurements of pulmonary valve peak gradient, structural heart defects and interventricular septal thickness.
Results:
We identified five women with Noonan syndrome (10 pregnancies). Three of five patients had pulmonary valve stenosis at the time of pregnancy, two of which had undergone cardiac procedures. 50% of pregnancies (5/10) resulted in pre-term birth. 80% (8/10) of all deliveries were converted to caesarean section after a trial of labour. One pregnancy resulted in intra-uterine fetal demise while nine pregnancies resulted in the birth of a living infant. 60% (6/10) of livebirths required care in the neonatal intensive care unit. One infant passed away at 5 weeks of age.
Conclusions:
The majority of mothers had pre-existing, though mild, heart disease. We found high rates of prematurity, conversion to caesarean section, and elevated level of care. No maternal complications resulted in long-term morbidity. Our study suggests that women with Noonan syndrome and low-risk cardiac lesions can become pregnant and deliver a healthy infant with counselling and risk evaluation.
Pooling of samples in detecting the presence of virus is an effective and efficient strategy in screening carriers in a large population with low infection rate, leading to reduction in cost and time. There are a number of pooling test methods, some being simple and others being complicated. In such pooling tests, the most important parameter to decide is the pool or group size, which can be optimised mathematically. Two pooling methods are relatively simple. The minimum numbers required in these two tests for a population with known infection rate are discussed and compared. Results are useful for identifying asymptomatic carriers in a short time and in implementing health codes systems.
Due to lack of data on the epidemiology, cardiac, and neurological complications among Ontario visible minorities (Chinese and South Asians) affected by coronavirus disease (COVID-19), this population-based retrospective study was undertaken to study them systematically.
Methods:
From January 1, 2020 to September 30, 2020 using the last name algorithm to identify Ontario Chinese and South Asians who were tested positive by PCR for COVID-19, their demographics, cardiac, and neurological complications including hospitalization and emergency visit rates were analyzed compared to the general population.
Results:
Chinese (N = 1,186) with COVID-19 were found to be older (mean age 50.7 years) compared to the general population (N = 42,547) (mean age 47.6 years) (p < 0.001), while South Asians (N = 3,459) were younger (age of 42.1 years) (p < 0.001). The 30-day crude rate for cardiac complications among Chinese was 169/10,000 (p = 0.069), while for South Asians, it was 64/10,000 (p = 0.008) and, for the general population, it was 112/10,000. For neurological complications, the 30-day crude rate for Chinese was 160/10,000 (p < 0.001); South Asians was 40/10,000 (p = 0.526), and general population was 48/10,000. The 30-day all-cause mortality rate was significantly higher for Chinese at 8.1% vs 5.0% for the general population (p < 0.001), while it was lower in South Asians at 2.1% (p < 0.001).
Conclusions:
Chinese and South Asians in Ontario affected by COVID-19 during the first wave of the pandemic were found to have a significant difference in their demographics, cardiac, and neurological outcomes.
In this paper, we describe the system design and capabilities of the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope at the conclusion of its construction project and commencement of science operations. ASKAP is one of the first radio telescopes to deploy phased array feed (PAF) technology on a large scale, giving it an instantaneous field of view that covers $31\,\textrm{deg}^{2}$ at $800\,\textrm{MHz}$. As a two-dimensional array of 36$\times$12 m antennas, with baselines ranging from 22 m to 6 km, ASKAP also has excellent snapshot imaging capability and 10 arcsec resolution. This, combined with 288 MHz of instantaneous bandwidth and a unique third axis of rotation on each antenna, gives ASKAP the capability to create high dynamic range images of large sky areas very quickly. It is an excellent telescope for surveys between 700 and $1800\,\textrm{MHz}$ and is expected to facilitate great advances in our understanding of galaxy formation, cosmology, and radio transients while opening new parameter space for discovery of the unknown.
A pooled sample analysis strategy for novel coronavirus (severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2)) is proposed for a large population in this paper. The population to be tested is divided into divisions based on earlier observed detection rate of SARS-CoV-2 first. Samples collected are then grouped in appropriate pooled size. The number of tests per person in that population is expressed as a function of two variables: the observed detection rate and the pooled size or number of samples grouped. The minimum number of tests per person can be further shown to be a function of only one of these two variables, because these two parameters are found to be related at this minimum. A management scheme on grouping the samples is proposed in order to reduce the number of tests, to save time, which is of utmost importance in fighting an epidemic. The proposed testing scheme will be useful for supporting the government in making decisions to handle regular routine detection tests for identifying asymptomatic patients and implementing health code system in large population of millions of citizens. Another important point is to use smaller number of test kits, allowing more resources to speed up the mass screening tests, particularly in places not so rich.
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of state. Neutron star mergers are expected to often produce rapidly rotating remnant neutron stars that emit gravitational waves. These will provide clues to the extremely hot post-merger environment. This signature of nuclear matter in gravitational waves contains most information in the 2–4 kHz frequency band, which is outside of the most sensitive band of current detectors. We present the design concept and science case for a Neutron Star Extreme Matter Observatory (NEMO): a gravitational-wave interferometer optimised to study nuclear physics with merging neutron stars. The concept uses high-circulating laser power, quantum squeezing, and a detector topology specifically designed to achieve the high-frequency sensitivity necessary to probe nuclear matter using gravitational waves. Above 1 kHz, the proposed strain sensitivity is comparable to full third-generation detectors at a fraction of the cost. Such sensitivity changes expected event rates for detection of post-merger remnants from approximately one per few decades with two A+ detectors to a few per year and potentially allow for the first gravitational-wave observations of supernovae, isolated neutron stars, and other exotica.
The Cultural Competent Assertive Community Treatment Team (ACTT) is a joint venture sponsored by Mount Sinai Hospital in partnership with Hong Fook Mental Health Association established in 1999. This is the first ever cultural diverse mental health program using the cultural competency model. It was developed in response to the cultural diverse needs from the culturally diverse communities and supported with the best evidence-based research.
Since the implementation of the program, we focused on identifying key issues that have facilitated or hindered the therapeutic alliances, patients’ service utilization and treatment compliance because of cultural differences in health concepts and health care systems.
We will present what we have learned in literature review and the best evidence-based practice guidelines. Key cultural issues we have encountered with our clients will be described. Methods and strategies that are effective in overcoming cultural differences will be highlighted. We will use a case illustration to demonstrate our innovations and adaptations and will highlight lessons and challenges we have learned during the process of developing the cultural competency model. Feedbacks from the audience would be also incorporated to formulate the “best practice” guidelines. The guidelines will contribute significantly to the understanding of the complexity of cultural factors in treating mental illness but also ensure the effective service delivery to cultural diverse population.
Cultural Competent Assertive Community Treatment Team has won American Psychiatric Foundation Advancing Minority Mental Health Award as well as the Leading Practice Award from Ontario Hospital Association in 2007.
The goal of this presentation is to introduce a new “Cultural Competency Training/Manual (CCTP) for Law and Mental Health professionals Working with persons involved with law and mental health” sponsored by a grant from the Law Foundation of Ontario and department of psychiatry of Mount Sinai Hospital.
The manual is qualitative which includes conducting a literature review, facilitation of multi-stakeholder focus groups, and interviewed key stakeholders, consultation with clinical staff from the Mount Sinai Hospital and other Court Support programs, to address the key challenges in working with culturally diverse persons involved with law and mental health. In the oral presentation, we will present key themes on the challenges in dealing with culturally-diverse persons involved in law and mental health. The themes were consistent with the literature, evidence-based research, and validated by actual provider experience. They include language and communication, mistrust of mainstream services, racism and discrimination, resistance from persons involved with law and mental health and their families, and the need for cultural competency practices, such as interpretation, cultural understanding, community and systemic support. With these themes in mind, we will demonstrate the application of practical skills and cultural competencies using vignettes. A cultural competency model of working with culturally diverse persons involved in law and mental health and the five key responsibilities will be introduced. They include the following domains: language and communication, system support and navigation, education and advocacy, and collaboration.
Professor Liu, President of Shenzhen Kangning Hospital, came to Canada in 2008 and learned that Assertive Community Treatment Team (hospital without walls) might be one of the solutions to the shortage of inpatient beds. I was invited to conduct site visits, consultations, training sessions and workshops for the mental health professionals in Shenzhen since 2009. Doctors and administrative staff from Shenzhen were sent to Toronto, Canada to learn about the program implementation. Finally the Shenzhen ACT in China was established in November 2012.
Objectives:
To describe the development and adaptation of ACT model in Shenzhen China. To report the success and challenges of ACTT development in China.
Methodology:
To define the history and the purpose, its principles, its internal structure, the team composition, team dynamics, the target population, its characteristics of Shenzhen ACT within the demographic context. I will share my subjective experience regarding my observation, my perspectives and a brief comparison with ACT Teams in Toronto, Canada will be highlighted.
Results:
The China Shenzhen ACT Team was born in an institutional context where the community mental health care was still novel and not having enough infrastructures to support the work.
Conclusions:
The Shenzhen ACT Team is the first ACT in China to experience the effectiveness and efficiency in taking care of severe mentally ill patients in the community. They have successfully implemented ACT service with the support from the hospital, municipal government and the neighbourhood community.
The Assertive Community Treatment (ACT) teams of Mount Sinai Hospital in Toronto and the KUINA Center, Hitachinaka, Japan, were compared with regard to ACT fidelity, organizational structure, populations served, and treatment outcomes. Ethnocultural adaptations to the ACT model made by both teams included enhanced family support and intervention, culturally and linguistically matched staff and patients when possible, culturally informed therapy, routine cultural assessments, culturally matched housing and community support, and flexible funding models.
Methods
Data were gathered by chart reviews (66 patients in Toronto and 40 patients in Japan), a satisfaction measure, a standard measure of ACT fidelity, a pre-post measure of treatment outcomes (the Brief Psychiatric Rating Scale), and hospitalization days.
Results
Both teams achieved good fidelity to ACT and reductions in hospitalization and symptom severity. Family satisfaction scores were high.
Conclusions
With culturally informed adaptations, ACT can be effective in a Canadian mixed ethnocultural population and a homogeneous Japanese population.
This paper investigates the recidivism of Mount Sinai Hospital mental health court support program in Toronto, Canada among patients involved in the criminal justice system. It also looks to find relationships between recidivism and factors including gender, age and ethnicity.
Method
Follow up periods of up to 48 months after the time of initial admission to the program was conducted and the frequency of re-offense was observed. Comparisons for the significance of risk factors were analyzed using t-tests and Chisquare tests.
Results
191 clients were admitted to the Mount Sinai Hospital Court Support Program between September 2001 and June 2007. At first admission, the mean ± s.d. age was 35.8 ± 9.8 years (range=18-74 years; n=184). The median age was 35 years. The modal age was 34 years. Of the 191 clients, 16 (8.4%) reoffended. Two of them (12.5%) had a third offense; and 1 (6.3%) had a total of four offenses within this tracking period. it appears that re-offense is more likely between 13 and 24 months. No re-offense was noted beyond the 48 months. The gender distribution was not significantly different between reoffenders and non-reoffenders. The mean age at first admission also did not differ between reoffenders and non-reoffenders. The distribution of ethnic groups among reoffenders and non-reoffenders did not differ.
Conclusions
The findings seem to indicate that recidivism has no relationship with gender, age and ethnic groups. The comprehensive and length of support services seem more important in preventing recidivism.
The existing literature on chronic pain points to the effects anxiety sensitivity, pain hypervigilance, and pain catastrophizing on pain-related fear; however, the nature of the relationships remains unclear. The three dispositional factors may affect one another in the prediction of pain adjustment outcomes. The addition of one disposition may increase the association between another disposition and outcomes, a consequence known as suppressor effects in statistical terms.
Objective
This study examined the possible statistical suppressor effects of anxiety sensitivity, pain hypervigilance and pain catastrophizing in predicting pain-related fear and adjustment outcomes (disability and depression).
Methods
Chinese patients with chronic musculoskeletal pain (n = 401) completed a battery of assessments on pain intensity, depression, anxiety sensitivity, pain vigilance, pain catastrophizing, and pain-related fear. Multiple regression analyses assessed the mediating/moderating role of pain hypervigilance. Structural equation modeling (SEM) was used to evaluate suppression effects.
Results
Our results evidenced pain hypervigilance mediated the effects of anxiety sensitivity (Model 1: Sobel z = 4.86) and pain catastrophizing (Model 3: Sobel z = 5.08) on pain-related fear. Net suppression effect of pain catastrophizing on anxiety sensitivity was found in SEM where both anxiety sensitivity and pain catastrophizing were included in the same full model to predict disability (Model 9: CFI = 0.95) and depression (Model 10: CFI = 0.93) (all P < 0.001) (see Figs. 3 and 4, Figs. 1 and 2).
Conclusions
Our findings evidenced that pain hypervigilance mediated the relationship of two dispositional factors, pain catastrophic cognition and anxiety sensitivity, with pain-related fear. The net suppression effects of pain catastrophizing suggest that anxiety sensitivity enhanced the effect of pain catastrophic cognition on pain hypervigilance.

While a body of research has evidenced the role of pain coping in chronic pain adjustment, the role of coping flexibility in chronic pain adjustment has received little research attention. Coping flexibility can be conceptualized with two dimensions, cognitive and behavioral. The cognitive dimension of coping flexibility (or coping appraisal flexibility) refers to one's appraisal of pain experience when changing coping strategies whereas the behavioral dimension of coping flexibility denotes the variety of coping responses individuals use in dealing with stressful demands.
Objective
The aim of this paper is to present preliminary findings on the role of coping flexibility in chronic pain adjustment by assessing 3 competing models of pain coping flexibility (see Figs. 1–3).
Methods
Patients with chronic pain (n = 300) completed a battery of questionnaire assessing pain disability, discriminative facility, need for closure, pain coping behavior, coping flexibility, and pain catastrophizing. The 3 hypothesized models were tested using structural equation modeling (SEM). In all models tested, need for closure and discriminative facility were fitted as the dispositional cognitive and motivational factors respectively underlying the coping mechanism, whereas pain catastrophizing and pain intensity were included as covariates.
Results
Results of SEM showed that the hierarchical model obtained the best data-model fit (CFI = 0.96) whereas the other two models did not attain an accept fit (CFI ranging from 0.70–0.72).
Conclusion
Our results lend tentative support for the hierarchical model of pain coping flexibility that coping variability mediated the effects of coping appraisal flexibility on disability.

Research evidenced the association of pain coping strategies with short-term and long-term adjustments to chronic pain. Yet, previous studies mainly assessed the frequency of coping strategies when pain occurs whilst no data is available on one's flexibility/rigidity in using different pain coping strategies, i.e., pain coping variability, in dealing with different situations.
Objectives
This study aimed to examine the multivariate association between pain coping variability and committed action in predicting concurrent pain-related disability. Specifically, we examined the independent effects of pain coping variability and committed action in predicting concurrent pain-related disability in a sample of Chinese patients with chronic pain.
Methods
Chronic pain patients (n = 287) completed a test battery assessing pain intensity/disability, pain coping strategies and variability, committed action, and pain catastrophizing. Multiple regression modeling compared the association of individual pain coping strategies and pain coping variability with disability (Models 1–2), and examined the independent effects of committed action and pain coping variability on disability (Model 3).
Results
Of the 8 coping strategies assessed, only guarding (std β = 0.17) was emerged as significant independent predictor of disability (Model 1). Pain coping variability (std β = −0.10) was associated with disability after controlling for guarding and other covariates (Model 2) and was emerged as independent predictor of disability (Model 3: std β = −0.11) (all P < 0.05) (Tables 1 and 2).
Conclusions
Our data offers preliminary support for the multivariate association between pain coping variability and committed action in predicting concurrent pain-related disability, which supplements the existing pain coping data that are largely based on assessing frequency of coping.

In this workshop, we will present the assertive community treatment (ACT) model in both Japan and Toronto, Canada. We will compare the adaptations of ACT models in both teams in order to serve their target populations efficiently and effectively.
We will also compare the demographic data, clinical data and the outcomes of both ACT teams by analysing the hospitalisation days, number of emergency admission and the number of admissions into hospitals. We will also highlight differences in the mental health systems in Japan and Canada in an attempt to formulate guidelines to ensure the effectiveness of ACT Teams in both countries. We would also like to open up discussion with the audiences and incorporate their ideas and suggestions in an attempt to formulate a competent mental health system which would effectively cater to the needs of people suffering severe mental health symptoms to ensure successful integration into the community.
Learning objectives:
– To explore adaptation in implementation of ACT in Japan and Canada;
– to develop a framework or model for assessing issues critical in establishing ACT in different countries;
– to develop guidelines to establish programs which will continuously be revised implementation based on needs, systems and feedback from the field.
