How Did an Integrated Health and Social Services Center in the Quebec Province Respond to the COVID-19 Pandemic? A Qualitative Case Study.

During the first and second waves of the pandemic, Quebec was among the Canadian provinces with the highest COVID-19 mortality rates. Facing particularly large COVID-19 outbreaks in its facilities, an integrated health and social services center in the province of Quebec (Canada), developed resilience strategies. To explore these diverse responses to the crisis, we conducted a case study analysis of a Quebec integrated health and social services center, building on a conceptualization of resilience strategies using "configurations" of effects, strategies, and impacts. Qualitative data from 14 indepth interviews conducted in the summer and fall of 2020 with managers and frontline practitioners were analyzed through the lens of situations of "anticipation," "reaction," or "inaction." The findings were discussed in three results dissemination workshops, two with practitioners and one with managers, to discern lessons they learned. Three major configurations emerged: 1) reorganization of services and spaces to accommodate more COVID-19 patients; 2) management of contamination risks for patients and professionals; and 3) management of personal protective equipment (PPE), supplies, and medications. Within these configurations, the responses to the crisis were strongly shaped by the 2015 health care system reforms in Quebec and were constrained by organizational challenges that included a centralized model of governance, a history of substantial budget cuts to longterm care facilities, and a systematic lack of human resources.

Predictors of no, low and frequent emergency department use for any medical reason among patients with cannabis-related disorders attending Quebec (Canada) addiction treatment centres.

INTRODUCTION: Patients with substance-related disorders and mental disorders (MD) contribute substantially to emergency department (ED) overcrowding. Few studies have identified predictors of ED use integrating service use correlates, particularly among patients with cannabis-related disorders (CRD). This study compared predictors of low (1-2 visits/year) or frequent (3+ visits/year) ED use with no ED use for a cohort of 9836 patients with CRD registered at Quebec (Canada) addiction treatment centres in 2012-2013. METHODS: This longitudinal study used multinomial logistic regression to evaluate clinical, sociodemographic and service use variables from various databases as predictors of the frequency of ED use for any medical reason in 2015-2016 among patients with CRD. RESULTS: Compared to non-ED users with CRD, frequent ED users included more women, rural residents, patients with serious MD and chronic CRD, dropouts from programs in addiction treatment centres and with less continuity of physician care. Compared with non-users, low ED users had more common MD and there more workers than students. DISCUSSION AND CONCLUSIONS: Multimorbidity, including MD, chronic physical illnesses and other substance-related disorders than CRD, predicted more ED use and explained frequent use of outpatient services and prior specialised acute care, as did being 12-29 years, after controlling for all other covariates. Better continuity of physician care and reinforcement of programs like assertive community or integrated treatment, and chronic primary care models may protect against frequent ED use. Strategies like screening, brief intervention and treatment referral, including motivational therapy for preventing treatment dropout may also be expanded to decrease ED use.

Profiles of individuals with cannabis-related disorders.

Background: Profiles of individuals with cannabis-related disorders (CRD) in specialized addiction treatment centers serving high-need patients have not been identified. This longitudinal study developed a typology for 9,836 individuals with CRD attending Quebec (Canada) addiction treatment centers in 2012-2013. Methods: Data on sociodemographic, clinical and service use variables were extracted from several databases for the years 1996-1997 to 2014-2015. Individual profiles were produced using Latent Class Analysis and compared predicting health outcomes on emergency department (ED) use, hospitalizations and suicidal behaviors for 2015-2016. Results: Six profiles were identified: 1-Older individuals, many living in couples and working, with moderate health problems, receiving intensive general practitioner (GP) care and high continuity of physician care; 2-Older individuals with chronic CRD, multiple social and health problems, and low health service use (chronic CRD referred to experiencing CRD for several years; social problems related to homelessness, unemployment, having criminal records or living alone); 3-Students with few social and health problems, and low health service use; 4-Young adults, many working, with few health problems, least health service use and continuity of physician care; 5-Youth, many working but some criminal offenders, with 1 or 2 years of CRD, few health problems and high addiction treatment center use; and 6-Older individuals with chronic CRD and multiple social and health problems, high health service use and continuity of physician care. Profiles 6 and 2 had the worst health outcomes. Conclusions: For Profiles 2 to 5, outreach and motivational services should be prioritized, integrated health and criminal justice services for profile 5 and, for Profiles 2 and 6, assertive community treatments. Screening, brief intervention and referrals to addiction treatment centers may also be encouraged for individuals with CRD, particularly those in Profile 2. This cohort had high social and health needs relative to services received, suggesting continued need for care.

Vitamin B-12 Intake from Dairy but Not Meat Is Associated with Decreased Risk of Low Vitamin B-12 Status and Deficiency in Older Adults from Quebec, Canada.

BACKGROUND: Vitamin B-12 deficiency can result in irreversible neurologic damages. It is most prevalent among older adults (∼5%-15%), mainly due to impaired absorption. Vitamin B-12 bioavailability varies between food sources, so their importance in preventing deficiency may also vary. OBJECTIVES: Using the NuAge Database and Biobank, we examined the associations between vitamin B-12 intake (total and by specific food groups) and low vitamin B-12 status and deficiency in older adults. METHODS: NuAge-the Quebec Longitudinal Study on Nutrition and Successful Aging-included 1753 adults aged 67-84 y who were followed 4 y. Analytic samples comprised 1230-1463 individuals. Dietary vitamin B-12 intake was assessed annually using three 24-h dietary recalls. Vitamin B-12 status was assessed annually as low serum vitamin B-12 (<221 pmol/L), elevated urinary methylmalonic acid (MMA)/creatinine ratio (>2 µmol/mmol), and a combination of both (deficiency). Vitamin B-12 supplement users were excluded. Multilevel logistic regressions, adjusted for relevant confounders, were used. RESULTS: Across all study years, 21.8%-32.5% of participants had low serum vitamin B-12, 12.5%-17.0% had elevated urine MMA/creatinine, and 10.1%-12.7% had deficiency. Median (IQR) total vitamin B-12 intake was 3.19 µg/d (2.31-4.37). Main sources were "dairy" and "meat, poultry, and organ meats." The ORs (95% CIs) in the fifth quintile compared with the first of total vitamin B-12 intake were as follows: for low serum vitamin B-12, 0.52 (0.37, 0.75; P-trend < 0.0001); for elevated urine MMA/creatinine, 0.63 (0.37, 1.08; P-trend = 0.091); and for vitamin B-12 deficiency, 0.38 (0.18, 0.79; P-trend = 0.006). Similarly, ORs (95% CIs) in the fourth quartile compared with the first of dairy-derived vitamin B-12 intake were 0.46 (0.32, 0.66; P-trend < 0.0001), 0.51 (0.30, 0.87; P-trend = 0.006), and 0.35 (0.17, 0.73; P-trend = 0.003), respectively. No associations were observed with vitamin B-12 from "meat, poultry, and organ meats." CONCLUSIONS: Higher dietary vitamin B-12 intake, especially from dairy, was associated with decreased risk of low vitamin B-12 status and deficiency in older adults. Food groups might contribute differently at reducing risk of deficiency in older populations.

Fisher's Linear Discriminant Function Analysis and its Potential Utility as a Tool for the Assessment of Health-and-Wellness Programs in Indigenous Communities.

Diabetes mellitus is a growing public health problem affecting persons in both developed and developing nations. The prevalence of type 2 diabetes mellitus (T2DM) is reported to be several times higher among Indigenous populations compared to their non-Indigenous counterparts. Discriminant function analysis (DFA) is a potential tool that can be used to quantitatively evaluate the effectiveness of Indigenous health-and-wellness programs (e.g., on-the-land programs, T2DM interventions), by creating a type of pre-and-post-program scoring system. As the communities of the Eeyou Istchee territory, subarctic Quebec, Canada, have varying degrees of isolation, we derived a DFA tool for point-of-contact evaluations to aid in monitoring and assessment of health-and-wellness programs in rural and remote locations. We developed several DFA models to discriminate between those with and without T2DM status using age, fasting blood glucose, body mass index, waist girth, systolic and diastolic blood pressure, high-density lipoprotein, triglycerides, and total cholesterol in participants from the Eeyou Istchee. The models showed a ~97% specificity (i.e., true positives for non-T2DM) in classification. This study highlights how varying risk factor models can be used to discriminate those without T2DM with high specificity among James Bay Cree communities in Canada.

Real-World Experience With Apremilast in the Treatment of Adults With Moderate to Severe Plaque Psoriasis in Québec: A Claims-Based Analysis of Drug Utilization and Healthcare Resource Utilization.

BACKGROUND: In Québec, targeted biologic therapies for moderate to severe plaque psoriasis are restricted to patients who have not responded to phototherapy or conventional systemic treatment, primarily due to high drug costs. Apremilast, an oral treatment for plaque psoriasis, was added to the Québec provincial health insurance plan (Régie de l'assurance maladie du Québec; RAMQ) formulary in 2015, making this the only province in Canada with public drug plan reimbursement for apremilast. OBJECTIVES: The aim of this study is to describe patients' characteristics, treatment patterns, healthcare resource utilization (HCRU), and associated costs and to measure real-world budget impact of using apremilast before biologics in plaque psoriasis. METHODS: This study was performed using RAMQ drug claims and medical services data. Patients diagnosed with psoriasis between January 2015 and December 2017 were identified. Medical services and prescription claims were categorized as all-cause and psoriasis-related. Using RAMQ database estimates, a 3-year budget impact analysis was developed comparing treatment cost with and without the addition of apremilast to the formulary. RESULTS: In all, 540 patients were identified (apremilast: n = 92; biologics: n = 448). Comorbidity burden and treatment persistence and adherence were comparable between apremilast and biologic users. The year following the index date, all-cause HCRU was lower for apremilast versus biologic users (CAN$19 763 vs CAN$28 025; P < .01), mainly driven by drug cost. Using apremilast before biologics resulted in an estimated RAMQ net savings of CAN$49 290 (2015), CAN$746 856 (2016), and CAN$1 216 512 (2017), and a total savings of CAN$2 012 658 since apremilast's addition to the formulary. CONCLUSION: Adding apremilast to the drug formulary of other Canadian provinces could result in significant healthcare savings.

Codesigning care improvements for women living with HIV: a patient-oriented deliberative dialogue workshop in Montréal, Quebec.

BACKGROUND: Care services have not been sufficiently adapted to meet the comprehensive care needs of women living with HIV. Our study objective was to engage patients and providers in codesigning care recommendations to improve care for this population in the province of Quebec. METHODS: We conducted a 5-hour deliberative dialogue workshop in April 2019 in Montréal as the final phase of a mixed-methods study investigating comprehensive care for women living with HIV. The study drew on data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS). Recruitment was guided by a purposive maximum-variation sampling strategy to ensure an appropriate mix of participants and was facilitated by our existing CHIWOS networks. Participants included patients (women living with HIV) and HIV care providers (doctors, nurses, pharmacists). The workshop was facilitated professionally and included a synthesis of the evidence, small- and large-group deliberations, and voting on care improvements. RESULTS: Eight patients and 8 HIV care providers participated. Drawing on identified care priorities, the participants identified 4 relatively rapid care improvements and 3 longer-term improvements. The rapid care improvements included delegating medical acts to members of multidisciplinary care teams; greater involvement of HIV community members within care settings and health care decision-making; creating a women's health information booklet; and increasing HIV education among all health care providers and raising awareness of women's care needs beyond HIV-specific care among HIV care providers. The longer-term care improvements included advocating for complete financial coverage of antiretroviral therapy within the government-sponsored Medicare program, facilitating access to allied care providers (e.g., physiotherapists and psychologists) and launching a population-wide campaign to increase awareness about the Undetectable = Untransmittable (U=U) initiative and other HIV advances. INTERPRETATION: The deliberative dialogue workshop yielded evidence-based, stakeholder-driven recommendations to improve the comprehensive care of women living with HIV in Quebec.

Prevalence and characteristics of Livestock-Associated Methicillin-Resistant Staphylococcus aureus (LA-MRSA) isolated from chicken meat in the province of Quebec, Canada.

This study was conducted to estimate the prevalence of Livestock-Associated Methicillin-Resistant Staphylococcus aureus (LA-MRSA) in retail chicken meat and broiler chickens from the Province of Quebec, Canada, and to characterize LA-MRSA isolates. A total of 309 chicken drumsticks and thighs were randomly selected in 2013 from 43 retail stores in the Monteregie. In addition, nasal swabs and caeca samples were collected in 2013-2014 from 200 broiler chickens of 38 different flocks. LA-MRSA was not detected in broiler chickens. Fifteen LA-MRSA isolates were recovered from four (1.3%) of the 309 chicken meat samples. Multi-Locus Sequence Typing (MLST) and SCCmec typing revealed two profiles (ST398-MRSA-V and ST8-MRSA-IVa), which were distinct using pulse-field gel electrophoresis (PFGE) and microarray (antimicrobial resistance and virulence genes) analyses. In addition to beta-lactam resistance, tetracycline and spectinomycin resistance was detected in all isolates from the 3 positive samples of the ST398 profile. Southern blot hybridization revealed that the resistance genes aad(D) and lnu(A), encoding resistances to aminoglycosides and lincosamides respectively, were located on plasmid. All isolates were able to produce biofilms, but biofilm production was not correlated with hld gene expression. Our results show the presence of two separate lineages of MRSA in retail chicken meat in Quebec, one of which is likely of human origin.

Inflammatory Bowel Disease and Risk of Birth Defects in Offspring.

BACKGROUND AND AIMS: The relationship between inflammatory bowel disease in pregnancy and birth defects is not understood. We evaluated whether Crohn's disease and ulcerative colitis in pregnant women were associated with the risk of birth defects in the offspring. METHODS: We undertook a retrospective cohort study of 2 184 888 pregnancies in Quebec, Canada, between 1989 and 2016. We calculated risk ratios [RR] and 95% confidence intervals [CI] for the association between inflammatory bowel disease and the risk of birth defects, using generalised estimating equations adjusted for maternal characteristics. We assessed associations in the period before 2000, when immunosuppressive biologic therapy and folic acid food fortification were not yet available, compared with the period after 2000 when these interventions were more widespread. RESULTS: This study included 13 099 women with Crohn's disease and 7798 with ulcerative colitis. Crohn's disease was associated with 1.90 times [95% CI 1.10-3.28] the risk of abdominal wall defects [gastroschisis, omphalocoele, and diaphragmatic hernia] and ulcerative colitis was associated with 1.53 times [95% CI 1.02-2.30] the risk of central nervous system defects. The association of Crohn's disease with abdominal wall defects was stronger before 2000 [RR 3.62, 95% CI 1.71-7.67] than after 2000 [RR 1.23, 95% CI 0.55-2.75]. Ulcerative colitis was associated with central nervous system defects regardless of time period. CONCLUSIONS: These findings suggest that inflammatory bowel disease is associated with the risk of abdominal wall and central nervous system defects, and that introduction of immunobiologic medications is unlikely to be associated with added risk.

Resource use for older people hospitalised due to injury in a Canadian integrated trauma system: a retrospective multicenter cohort study.

BACKGROUND: Injuries represent one of the leading causes of preventable morbidity and mortality. For countries with ageing populations, admissions of injured older patients are increasing exponentially. Yet, we know little about hospital resource use for injured older patients. Our primary objective was to evaluate inter-hospital variation in the risk-adjusted resource use for injured older patients. Secondary objectives were to identify the determinants of resource use and evaluate its association with clinical outcomes. METHODS: We conducted a multicenter retrospective cohort study of injured older patients (≥65 years) admitted to any trauma centres in the province of Quebec (2013-2016, N = 33,184). Resource use was estimated using activity-based costing and modelled with multilevel linear models. We conducted separate subgroup analyses for patients with trauma and fragility fractures. RESULTS: Risk-adjusted resource use varied significantly across trauma centres, more for older patients with fragility fractures (intra-class correlation coefficients [ICC] = 0.093, 95% CI [0.079, 0.102]) than with trauma (ICC = 0.047, 95% CI = 0.035-0.051). Risk-adjusted resource use increased with age, and the number of comorbidities, and varied with discharge destination (P < 0.001). Higher hospital resource use was associated with higher incidence of complications for trauma (Pearson correlation coefficient [r] = 0.5, 95% CI = 0.3-0.7) and fragility fractures (r = 0.5, 95% CI = 0.3-0.7) and with higher mortality for fragility fractures (r = 0.4, 95% CI = 0.2-0.6). CONCLUSIONS: We observed significant inter-hospital variations in resource use for injured older patients. Hospitals with higher resource use did not have better clinical outcomes. Hospital resource use may not always positively impact patient care and outcomes. Future studies should evaluate mechanisms, by which hospital resource use impacts care.

La Maison Bleue: Strengthening resilience among migrant mothers living in Montreal, Canada.

INTRODUCTION: La Maison Bleue is a community-based perinatal health and social centre in Montreal that provides services during pregnancy up to age five to families living in vulnerable contexts. The study aimed to describe: 1) the challenges and protective factors that affect the well-being of migrant families receiving care at La Maison Bleue; and 2) how La Maison Bleue strengthens resilience among these families. METHODS: We conducted a focused ethnography. Immigrants, refugees, asylum seekers and undocumented migrants were invited to participate. We collected data from November to December 2017 via semi-structured interviews and participant observation during group activities at La Maison Bleue. Data were thematically analysed. RESULTS: Twenty-four mothers participated (9 interviewed, 17 observed). Challenges to well-being included family separation, isolation, loss of support, the immigration process, an unfamiliar culture and environment, and language barriers. Key protective factors were women's intrinsic drive to overcome difficulties, their positive outlook and ability to find meaning in their adversity, their faith, culture and traditions, and supportive relationships, both locally and transnationally. La Maison Bleue strengthened resilience by providing a safe space, offering holistic care that responded to both medical and psychosocial needs, and empowering women to achieve their full potential towards better health for themselves and their families. CONCLUSION: Migrant mothers have many strengths and centres like La Maison Bleue can offer a safe space and be an empowering community resource to assist mothers in overcoming the multiple challenges that they face while resettling and raising their young children in a new country.

A complementary approach to the vaccination promotion continuum: An immunization-specific motivational-interview training for nurses.

AIM: To develop and validate immunization-specific motivational-interview (MI) training for immunization nurses. BACKGROUND: We previously demonstrated that a MI-based intervention on immunisation, performed during postpartum by MI-trained healthcare workers at the hospital maternity ward, reduced parental vaccine hesitancy (VH) and increased vaccine coverage of their children. In this study, we propose immunization-specific MI training for immunization nurses. Together, MI-based training and interventions provide complementary approaches to existing strategies along the vaccination promotion continuum. DESIGN: Multiple pretest/posttest design with questionnaires self-administered before and after each training days (4 time points). METHODS: We developed an in-person immunization-specific MI-training workshop for immunization nurses, held on two days three months apart, with 7 h of MI-training dispensed on day 1, and 4 h on day 2. The self-administered Motivational Interviewing Skills in Immunization (MISI) questionnaire was used at four time points (before and after each of the 2 training days) to evaluate three core aspects of participant MI training: (1) MI-knowledge acquisition; (2) MI-skills application and (3) self-rated self-confidence in applying MI knowledge and skills in vaccination clinical practice. Between November 2016 to December 2017, 34 immunization nurses enrolled in our MI-training workshops. RESULTS: The immunization-specific MI-training improved the three core areas evaluated in participants i.e. MI-knowledge acquisition, MI-skills application, and self-rated self-confidence in applying these in vaccination clinical practice. CONCLUSIONS: Our immunization-specific MI-training enabled immunization nurses to significantly improve MI knowledge, skills and self-confidence in applying MI in the clinic. These results, taken together with those on the MI-based intervention for parents that we previously reported, support the notion of proposing validated immunization-specific MI training for immunization nurses in order to curb parental VH. IMPACT: Immunization-specific MI-training would be easily amenable for the training of other health professionals in the field of immunization to help promote vaccination and curb parental VH.

Determinants of selenoneine concentration in red blood cells of Inuit from Nunavik (Northern Québec, Canada).

Selenium (Se) is a trace mineral essential to human health, and is especially abundant in marine foods consumed by Inuit populations in Nunavik (northern Quebec, Canada), leading to exceptionally high whole blood Se levels. While most epidemiological studies to date examine plasma or whole blood Se, little is known about the health implications of specific Se biomarkers (e.g. selenoproteins and small Se compounds). Selenoneine, a novel Se compound, is found in high concentrations in marine foods (and particularly beluga mattaaq) and the red blood cells (RBCs) of populations that consume them. We report here RBC selenoneine concentrations in a population of Inuit adults (n = 885) who participated in the Qanuippitaa? 2004 survey. Simple associations between RBC selenoneine and other Se and mercury (Hg) biomarkers were assessed using Spearman correlations and linear regressions. Wilcoxon ranksum tests were used to examine differences in biomarkers and characteristics between tertiles of RBC selenoneine concentration. A multiple linear regression analysis was used to determine factors (sociodemographic, lifestyle, and dietary) associated with RBC selenoneine concentrations. Selenoneine comprised a large proportion of whole blood Se and RBC Se in this population. Age and sex-adjusted geometric mean RBC selenoneine concentration was 118 µg/L (range: 1-3226 µg/L) and was much higher (p = 0.001) among women (150.3 µg/L) than men (87.6 µg/L) across all regions of Nunavik after controlling for age, region, and diet. RBC selenoneine was highly correlated with RBC Se (rs = 0.96, p < 0.001) and whole blood Se (rs = 0.89, p < 0.001), but only weakly correlated with plasma Se (rs = 0.13, p < 0.001). Overall, increasing age (standardized ß = 0.24), higher body-mass index (BMI; ß = 0.08), female sex (ß = 0.10), living in a Hudson Strait community (compared to Hudson Bay and Ungava Bay; ß = 0.38), and consuming beluga mattaaq (g/day; ß = 0.19) were positively associated with RBC selenoneine. Meanwhile, consumption of market meats (g/day; ß = -0.07) was negatively associated with RBC selenoneine. RBC selenoneine is an important biomarker of Se dietary intake from local marine foods in Inuit populations. Further studies are needed to examine the health effects of selenoneine intake and the underlying mechanisms for sex differences among Inuit populations.

[Prevention of suicide of the elderly in France. To a multimodal strategy against depression and isolation: CQFDi]. / Prévention du suicide des personnes âgées en France. Vers une stratégie multimodale de lutte contre la dépression et l'isolement : CQFDi.

ISSUE: Suicide is a major problem of public health around the world, and if suicidal mortality rates have declined in recent years, the elderly remain a category of the world's population at major risk of suicide. Seventeen percent of deaths by suicide across the world are individuals over the age of 65. The existence of suicidal ideas for an individual in this age group increases the risk of suicide attempt in the year by 34. In France, about a little less than a quarter of suicides belong to persons over 60-years-old. More risk factors found in the international literature are in the foreground of mental disorders and in particular the major depression episode, then secondarily addictions, neuro-degenerative disorders as well as pain and other diseases. Depression is found in 60% to 90% of suicides. We notice also that older people privileged the general practitioner as interlocutor to discuss their problems and worries much more than psychiatrists or psychologists. In fact, two-thirds of the elderly who committed suicide had consulted their general practioner in the month prior to suicide and half in the 10 last days. That raises the question of the identification of depression and the evaluation of suicidal risk. On the other side, there is an abundant literature about psychosocial risk factors especially on the influence of isolation and lack of social support as well as on conflicts and family losses. In France, more than 4 million of the elderly live alone. So, while the world population is increasing and life expectancy lengthens, it is important to already act for elderly suicide prevention. PERSPECTIVES: Suicide prevention actions whose efficacity have been demonstrated around the world are designed as part of multimodal strategies combining several levers of action. The consensual recommendations for prevention of elderly suicide recommend the association of actions on the reduction of depression and combating social isolation in connection with the training of front-line actors such as general practitioners. As a result of these experiments and recommendations, the first francophone multimodal strategy was developed to act both on depression and social isolation: the Coopération Québec France sur la dépression et l'isolement (CQFDi) program which will be implemented in France and Quebec in 2019. CONCLUSION: It has been proven that multimodal suicide prevention strategies allow a reduction in the number of suicides. The CQFDi program focuses on at risk of suicide population and aims to reduce the suicide rate of elderly people in France.

A pragmatic randomized controlled trial of group transdiagnostic cognitive-behaviour therapy for anxiety disorders in primary care: study protocol.

BACKGROUND: Anxiety disorders are the most common mental disorders in community settings, and they are associated with significant psychological distress, functional and social impairment. While cognitive behaviour therapy (CBT) is the most consistently efficacious psychological treatment for anxiety disorders, barriers preclude widespread implementation of CBT in primary care. Transdiagnostic group CBT (tCBT) focuses on cognitive and behavioural processes and intervention strategies common to different anxiety disorders, and could be a promising alternative to conventional CBT. This study aims to examine the effectiveness of a transdiagnostic group CBT for anxiety disorders program as a complement to treatment-as-usual (TAU) in primary mental health care. METHODS/DESIGN: The trial is a multicentre pragmatic randomized controlled trial with a pre-treatment, post-treatment, and follow-up at 4, 8 and 12-months design. Treatment and control groups. a) tCBT (12 weekly 2-h group sessions following a manualized treatment protocol); b) TAU for anxiety disorders. Inclusion criteria comprise meeting DSM-5 criteria for primary Panic Disorder, Agoraphobia, Social Anxiety Disorder and/or Generalized Anxiety Disorder. Patients are recruited in three regions in the province of Quebec, Canada. The primary outcome measures are the self-reported Beck Anxiety Inventory and the clinician-administered Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5); secondary outcome measures include treatment responder status based on the ADIS-5, and self-reported instruments for specific anxiety and depression symptoms, quality of life, functioning, and service utilisation. STATISTICAL ANALYSIS: Intention-to-treat analysis. A mixed effects regression model will be used to account for between- and within-subject variations in the analysis of the longitudinal effects of the intervention. DISCUSSION: This rigorous evaluation of tCBT in the real world will provide invaluable information to decision makers, health care managers, clinicians and patients regarding the effectiveness of the intervention. Widespread implementation of tCBT protocols in primary care could lead to better effectiveness, efficiency, access and equity for the large number of patients suffering from anxiety disorders that are currently not obtaining evidence-based psychotherapy. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02811458 .

Trimester-Specific Dietary Intakes in a Sample of French-Canadian Pregnant Women in Comparison with National Nutritional Guidelines.

Diet during pregnancy greatly impacts health outcomes. This study aims to measure changes in dietary intakes throughout trimesters and to assess pregnant women’s dietary intakes in comparison with current Canadian nutritional recommendations. Seventy-nine pregnant women were recruited and completed, within each trimester, three Web-based 24-h dietary recalls and one Web questionnaire on supplement use. Dietary intakes from food, with and without supplements, were compared to nutritional recommendations throughout pregnancy. Energy and macronutrient intakes remained stable throughout pregnancy. A majority of women exceeded their energy and protein requirements in the first trimester, and fat intakes as a percentage of energy intakes were above recommendations for more than half of the women in all trimesters. Supplement use increased dietary intakes of most vitamins and minerals, but 20% of women still had inadequate total vitamin D intakes and most women had excessive folic acid intakes. This study showed that pregnant women did not increase their energy intakes throughout pregnancy as recommended. Furthermore, although prenatal supplementation reduces the risk of inadequate intake for most micronutrients, there is still a risk of excessive folic acid and insufficient vitamin D intake, which needs further investigation.

Plasma levels of selenium-containing proteins in Inuit adults from Nunavik.

Selenium (Se) is highly abundant in marine foods traditionally consumed by Inuit of Nunavik (Northern Quebec, Canada) and accordingly, their Se intake is among the highest in the world. However, little is known regarding the biological implications of this high Se status in this Arctic indigenous population. We used a method combining affinity chromatography and inductively coupled plasma-mass spectrometry with quantification by post-column isotope dilution to determine total Se levels and concentrations of Se-containing proteins in archived plasma samples of Inuit adults who participated to the 2004 Nunavik Inuit Health Survey (N = 852). Amounts of mercury (Hg) associated with Se-containing proteins were also quantified. Results show that glutathione peroxidase 3 (GPx3), selenoprotein P (SelP) and selenoalbumin (SeAlb) represented respectively 25%, 52% and 23% of total plasma Se concentrations. In addition, small amounts of Hg co-eluted with each Se-containing protein and up to 50% of plasma Hg was associated to SelP. Total plasma Se concentrations (median = 139 µg L− 1; interquartile range (IQR) = 22.7 µg L− 1) were markedly lower and less variable than whole blood Se concentration (median = 261 µg L− 1, IQR = 166 µg L− 1). A non linear relation was observed between whole blood Se and plasma Se levels, with plasma Se concentrations leveling off at approximately 200 µg L− 1, whereas 16% and 3% of individuals exhibited whole blood concentrations higher than 500 µg L− 1 and 1000 µg L− 1, respectively. In contrast, a linear relationship was previously reported in communities consuming Brazil nuts which are rich Se, mainly present as selenomethionine. This suggests that a different selenocompound, possibly selenoneine, is present in the Arctic marine food chain and accumulates in the blood cellular fraction of Inuit.

Escherichia coli antimicrobial susceptibility profile and cumulative antibiogram to guide empirical treatment of uncomplicated urinary tract infections in women in the province of Québec, 2010-15.

OBJECTIVES: Empirical treatment of uncomplicated urinary tract infections (UTIs) in women should be based on local susceptibility data. We aimed to generate regional and provincial cumulative antibiograms combining data from different laboratory information systems and determine the impact of basic patient characteristics on susceptibility results. METHODS: All positive urine samples for Escherichia coli obtained from women aged 18-65 years old in outpatient settings between 1 April 2010 and 31 March 2015 from four hospitals in Quebec, Canada, were included. The cumulative antibiogram for ciprofloxacin, nitrofurantoin and trimethoprim/sulfamethoxazole was calculated. A clinically significant difference in susceptibility profile was defined as factor(s) that lowered the susceptibility proportion below 80%. RESULTS: A total of 36 293 positive urine cultures were analysed. In the last year of the study, the proportion of susceptibility for ciprofloxacin, nitrofurantoin and trimethoprim/sulfamethoxazole was 90.3%, 95.4% and 81.9%, respectively. The susceptibility proportion was <80% for trimethoprim/sulfamethoxazole in the Montreal region (73.4%; 95% CI 71.1%-75.9%), whereas it remained >80% for the other regions. A significant decrease in susceptibility with time was identified for ciprofloxacin (92.1%-90.3%, P < 0.001) and nitrofurantoin (97.1%-95.4%, P < 0.001). Increasing age, recent hospitalization and site of collection were associated with an increase in resistance for certain antibiotics. CONCLUSIONS: Overall, all first-line antimicrobials remain acceptable choices for empirical treatment of uncomplicated UTIs in women in Quebec. The regional variability in susceptibility data within a single province emphasizes the importance of local susceptibility data to inform the development of empirical treatment guidelines for UTIs.

Predictors of Ventricular Arrhythmias and Sudden Death in a Québec Cohort With Brugada Syndrome.

BACKGROUND: Patients with Brugada syndrome (BrS) are at risk for ventricular arrhythmias (VAs) and sudden death. Identification of high-risk individuals beyond those with syncope or resuscitated sudden death remains a major challenge. METHODS: We assessed the value of clinical, electrophysiological, and electrocardiographic (ECG) features, including depolarization and repolarization metrics, in predicting arrhythmic events and sudden death in consecutive patients with BrS diagnosed between 2002 and 2013 in Quebec, Canada. Qualifying electrocardiograms with the highest type 1 ST-segment elevations were reviewed and analyzed by 2 electrophysiologists who were blinded to clinical history. Survival analyses were adjusted for Firth bias correction and left truncation. RESULTS: A total of 105 patients, 79.8% of whom were men, were diagnosed with BrS at a mean age of 46.2 ± 13.3 years and were followed for 59.6 ± 16.4 months. Ten (9.5%) had a history of cardiac arrest, 37 (35.2%) had syncope, and 7 (6.7%) experienced 20 arrhythmic events during follow-up, all consisting of appropriate ICD therapy (7 antitachycardia pacing; 13 shocks). In multivariate Cox regression analyses, a spontaneous type 1 electrocardiographic (ECG) pattern (hazard ratio [HR], 10.80; 95% confidence interval [CI], 1.03-113.87; P = 0.0476), maximal T peak-end (Tp-e) duration ≥ 100 ms (HR, 29.73; 95% CI, 1.33-666.37; P = 0.0325), and QRS duration in lead V6 > 110 ms (HR, 15.27; 95% CI, 1.07-217.42; P = 0.0443) were independently associated with VAs or aborted sudden cardiac death. CONCLUSIONS: In a multicentre cohort with BrS from Quebec, Canada, VAs and sudden death were independently associated with standard 12-lead ECG features, including a spontaneous type 1 pattern, depolarization (QRS in lead V6), and repolarization (maximal Tp-e duration) criteria.

Back to the Future: Penicillin-Susceptible Staphylococcus aureus.

BACKGROUND: Widespread penicillin usage rapidly resulted in the emergence of penicillin resistance in Staphylococcus aureus. However, new data suggest that penicillin susceptibility may be in a period of renaissance. The objective of our study was to quantify penicillin resistance in methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. METHODS: We retrospectively reviewed all adult MSSA bacteremia from April 2010 to April 2015 at the McGill University Health Centre (Montreal, QC, Canada). Susceptibility to penicillin, erythromycin, clindamycin, and trimethoprim-sulfamethoxazole (TMP-SMX) was determined in accordance with the Clinical & Laboratory Standards Institute guidelines. RESULTS: There were 324 unique episodes of MSSA bacteremia. Ninety (28%) isolates were susceptible to penicillin, 229 (71%) to erythromycin, 239 (74%) to clindamycin, and 317 (98%) to TMP-SMX. Isolates that were penicillin resistant were more likely to also be resistant to other antibiotics, but a statistically significant association was apparent only for erythromycin resistance (76/234, 32.2% vs 19/90, 21.1%, P = .04). The median age of patients was 67.5 years (interquartile range 52-78) and overall in-hospital 30-day mortality was 16.3% (53 deaths). After adjustment for patient age, there was no association between penicillin resistance and either intensive care unit admission or death. CONCLUSION: More than one-quarter of patients with MSSA bacteremia potentially could be treated with parenteral penicillin, which may offer pharmacokinetic advantages over other beta-lactam drugs and potentially improved outcomes.
