Trends in Mental Health Service Use Among Youth and Emerging Adults in Canada

Mental disorders among youth (age 12 to 17) and emerging adults (18 to 24) in Canada are common, but few receive mental health (MH) services. We examined trends in patterns and predictors of MH service use in this population. Secondary data analyses were conducted on six cycles of the Canadian Community Health Survey (2011 to 2016). From 2011 to 2016, the prevalence of MH service use increased by 4.3%. In 2016, 85.1% of those with poor self-rated MH accessed services, greater than in previous years; however, this subgroup represents only 1% of the total population. Psychiatrists had the largest provider caseload; social workers had the smallest. Sex, ethnicity, self-rated MH status, and mood or anxiety disorder consistently predicted likelihood of MH service use across time. The increased patterns of MH service use and variation in predictors of service use highlight the need for an effective and equitable mental healthcare system

Adaptation and qualitative evaluation of the BETTER intervention for chronic disease prevention and screening by public health nurses in low income neighbourhoods : views of community residents

The adaptation phase is one component of a study funded as a grant proposal entitled 'Advancing Cancer Prevention Among Deprived Neighbourhoods' by the Canadian Cancer Society Research Institute grant #704042 and by the Canadian Institutes of Health Research Institute of Cancer grant OCP #145450.

Lawrence Paszat is supported by a Clinician Scientist award funded by the Ontario Ministry of Health and Long Term Care.Background The BETTER intervention is an effective comprehensive evidence-based program for chronic disease prevention and screening (CDPS) delivered by trained prevention practitioners (PPs), a new role in primary care. An adapted program, BETTER HEALTH, delivered by public health nurses as PPs for community residents in low income neighbourhoods, was recently shown to be effective in improving CDPS actions. To obtain a nuanced understanding about the CDPS needs of community residents and how the BETTER HEALTH intervention was perceived by residents, we studied how the intervention was adapted to a public health setting then conducted a post-visit qualitative evaluation by community residents through focus groups and interviews. Methods We first used the ADAPT-ITT model to adapt BETTER for a public health setting in Ontario, Canada. For the post-PP visit qualitative evaluation, we asked community residents who had received a PP visit, about steps they had taken to improve their physical and mental health and the BETTER HEALTH intervention. For both phases, we conducted focus groups and interviews; transcripts were analyzed using the constant comparative method. Results Thirty-eight community residents participated in either adaptation (n = 14, 64% female; average age 54 y) or evaluation (n = 24, 83% female; average age 60 y) phases. In both adaptation and evaluation, residents described significant challenges including poverty, social isolation, and daily stress, making chronic disease prevention a lower priority. Adaptation results indicated that residents valued learning about CDPS and would attend a confidential visit with a public health nurse who was viewed as trustworthy. Despite challenges, many recipients of BETTER HEALTH perceived they had achieved at least one personal CDPS goal post PP visit. Residents described key relational aspects of the visit including feeling valued, listened to and being understood by the PP. The PPs also provided practical suggestions to overcome barriers to meeting prevention goals. Conclusions Residents living in low income neighbourhoods faced daily stress that reduced their capacity to make preventive lifestyle changes. Key adapted features of BETTER HEALTH such as public health nurses as PPs were highly supported by residents. The intervention was perceived valuable for the community by providing access to disease prevention. Trial registration #NCT03052959, 10/02/2017.Peer reviewe

Building on existing tools to improve chronic disease prevention and screening in public health : a cluster randomized trial

This study was funded as a grant proposal entitled ‘Advancing Cancer Prevention Among Deprived Neighbourhoods’ by the Canadian Cancer Society Research Institute grant #704042 and by the Canadian Institutes for Health Research Institute of Cancer grant OCP #145450. AL is supported by a CIHR New Investigator Award, and as Chair in Implementation Science at the Peter Gilgan Centre for Women’s Cancers at Women’s College Hospital in partnership with the Canadian Cancer Society.Background The BETTER (Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Primary Care) intervention was designed to integrate the approach to chronic disease prevention and screening in primary care and demonstrated effective in a previous randomized trial. Methods We tested the effectiveness of the BETTER HEALTH intervention, a public health adaptation of BETTER, at improving participation in chronic disease prevention and screening actions for residents of low-income neighbourhoods in a cluster randomized trial, with ten low-income neighbourhoods in Durham Region Ontario randomized to immediate intervention vs. wait-list. The unit of analysis was the individual, and eligible participants were adults age 40–64 years residing in the neighbourhoods. Public health nurses trained as “prevention practitioners” held one prevention-focused visit with each participant. They provided participants with a tailored prevention prescription and supported them to set health-related goals. The primary outcome was a composite index: the number of evidence-based actions achieved at six months as a proportion of those for which participants were eligible at baseline. Results Of 126 participants (60 in immediate arm; 66 in wait-list arm), 125 were included in analyses (1 participant withdrew consent). In both arms, participants were eligible for a mean of 8.6 actions at baseline. At follow-up, participants in the immediate intervention arm met 64.5% of actions for which they were eligible versus 42.1% in the wait-list arm (rate ratio 1.53 [95% confidence interval 1.22–1.84]). Conclusion Public health nurses using the BETTER HEALTH intervention led to a higher proportion of identified evidence-based prevention and screening actions achieved at six months for people living with socioeconomic disadvantage.Publisher PDFPeer reviewe

Pesticide use and opportunities of exposure among farmers and their families: cross-sectional studies 1998-2006 from Hebron governorate, occupied Palestinian territory

<p>Abstract</p> <p>Background</p> <p>Adverse health effects caused by pesticide exposure have been reported in occupied Palestinian territory and the world at large. The objective of this paper is to compare patterns of pesticide use in Beit-U'mmar village, West Bank, between 1998 and 2006.</p> <p>Methods</p> <p>We studied two populations in Beit-U'mmar village, comprised of: 1) 61 male farmers and their wives in 1998 and 2) 250 male farmers in 2006. Both populations completed a structured interview, which included questions about socio-demographic factors, types of farming tasks, as well as compounds, quantities, and handling of pesticides. Using the 1998 population as a reference, we applied generalized linear regression models (GLM) and 95% confidence intervals (CI) in order to estimate prevalence differences (PD) between the two populations.</p> <p>Results</p> <p>In 1998, farmers used 47 formulated pesticides on their crops. In 2006, 16 of these pesticides were still in use, including five internationally banned compounds. There were positive changes with less use of large quantities of pesticides (>40 units/year) (PD -51; CI -0.60, -0.43), in applying the recommended dosage of pesticides (PD +0.57; CI +0.48, +0.68) and complying with the safety period (PD +0.89; CI+0.83, +0.95). Changes also included farmers' habits while applying pesticides, such as less smoking (PD -0.20; CI-0.34, -0.07) and eating at the work place (PD -0.33; CI-0.47, -0.19). No significant changes were found from 1998 to 2006 regarding use of personal protective equipment, pesticide storage, farmers' habits after applying pesticides, and in using some highly hazardous pesticides.</p> <p>Conclusions</p> <p>The results were based on two cross-sectional surveys and should be interpreted with caution due to potential validity problems. The results of the study suggest some positive changes in the handling of pesticides amongst participants in 2006, which could be due to different policy interventions and regulations that were implemented after 1998. However, farm workers in Beit -U'mmar village are still at risk of health effects because of ongoing exposure to pesticides. To the best of our knowledge, no studies on long-term changes in pesticide use have been reported from developing countries.</p

Mortality and pulmonary complications in patients undergoing surgery with perioperative sars-cov-2 infection: An international cohort study

Background The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (740%) had emergency surgery and 280 (248%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (261%) patients. 30-day mortality was 238% (268 of 1128). Pulmonary complications occurred in 577 (512%) of 1128 patients; 30-day mortality in these patients was 380% (219 of 577), accounting for 817% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 175 [95% CI 128-240], p&lt;00001), age 70 years or older versus younger than 70 years (230 [165-322], p&lt;00001), American Society of Anesthesiologists grades 3-5 versus grades 1-2 (235 [157-353], p&lt;00001), malignant versus benign or obstetric diagnosis (155 [101-239], p=0046), emergency versus elective surgery (167 [106-263], p=0026), and major versus minor surgery (152 [101-231], p=0047). Interpretation Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Phytotherapy for Polycystic Ovarian Syndrome: A review of the literature and evaluation of practitioners’ experiences

Background: Polycystic Ovarian Syndrome (PCOS) is a common, complex, endocrine condition with potential long-term cardiovascular, endocrine and metabolic health implications. Currently, there exists no medical treatment that addresses all clinical presentations. Herbal practitioners often treat women with PCOS; yet, there is a lack of research investigating PCOS and herbal treatment. This study aimed to examine the current scientific literature on PCOS and phytotherapy, explore practitioners’ experiences treating women with the syndrome and evaluate whether there is a role for phytotherapy in the treatment of PCOS. Methods: A literature search was conducted using the terms; ‘Polycystic Ovarian Syndrome’ / ‘PCOS’ and ‘phytotherapy’/‘herbal medicine’ / ‘herbs’. The published research identified by these terms was then reviewed. A brief questionnaire with a mix of eleven open and closed questions was sent to herbal practitioners on the National Institute of Medical Herbalists (NIMH) 2012 register. Results: The literature review found promising results for the use of Mentha spicata, Cinnamomum verum and berberine containing herbs. There was a weaker evidence base for the use of Glycyrrhiza glabra and Paeonia lactiflora. The questionnaire was completed by 72 practitioners, 71 % had treated women with PCOS. The majority (38%, n=50) felt herbal medicine was ‘quite successful’ in treating PCOS. The average time until herbal treatment started to be successful was 3.2 months. The most frequently used herbs were Paeonia lactiflora, Glycyrrhiza glabra and Vitex agnus castus. Dietary and lifestyle advice emerged as frequently identified therapeutic interventions. Conclusions: This exploratory study suggests that there is a role for phytotherapy in the treatment of PCOS. Further investigation, consisting of well-designed clinical trials and monitoring the successful use of herbal medicine by practitioners, is clearly necessary. This future research would serve to substantiate positive empirical evidence, constructing a more robust evidence base for the effective use of phytotherapy as a therapeutic option for women with PCOS

Metformin Attenuates Hepatic Mitochondrial Dysfunction and Oxidative Stress in a Model of Burn Injury

Elderly burn patients are a high-risk group with poor survival rates. The incidence of organ failure for elderly burns is particularly high, and the organs typically affected, such as the liver, are mitochondria rich. This suggests that mitochondria underly the vulnerability of the elderly to burns, and thus treatments directly targeting mitochondria, such as metformin, may improve their outcome. Thus, we hypothesize that the elderly have a worse outcome due to faulty hepatic mitochondria and that metformin intervention would enable recovery. Our data shows that while adult murine mitochondria rebound from the initial insult, older animals display delayed recovery of mitochondrial bioenergetics. Moreover, metformin treatment suppresses the hypermetabolic mitochondria of the younger cohort while significantly increasing respiration in the aged group. These findings suggest that aging leads to a failure to normalize hepatic mitochondria after trauma and that metformin is a possible agent that can restore mitochondrial responses to burns.M.Sc
