    Abstract This study investigated the association between post-stroke fatigue and inability to return to work/drive in young patients aged <60 years with first stroke who were employed prior to infarct while controlling for stroke severity, age, extent of disability, cognitive function, and depression. The Fatigue Severity Scale (FSS) was used to evaluate post-stroke fatigue in this 1-year prospective cohort study. Follow-ups were completed at 3, 6, and 12 months post rehabilitation discharge. A total of 112 patients were recruited, 7 were excluded, due to loss to follow-up (n = 6) and being palliative (n = 1), resulting in 105 participants (71% male, average age 49 ±10.63 years). Stroke patients receiving both inpatient and outpatient rehabilitation were consecutively recruited. Persistent fatigue remained associated with inability to return to work when controlling for other factors at 3 months (adjusted OR = 18, 95% CI: 2.9, 110.3, p = 0.002), 6 months (adjusted OR = 29.81, 95% CI: 1.7, 532.8, p = 0.021), and 12 months (adjusted OR = 31.6, 95% CI: 1.8, 545.0, p = 0.018). No association was found between persistent fatigue and return to driving. Fatigue at admission was associated with inability to return to work at 3 months but not return to drive. Persistent fatigue was found to be associated with inability to resume work but not driving. It may be beneficial to routinely screen post-stroke fatigue in rehabilitation and educate stroke survivors and employers on the impacts of post-stroke fatigue on return to work.

    Abstract Abstract: The next era of assessment in medical education promises new assessment systems, increased focus on ensuring high-quality equitable patient care, and precision education to drive learning and improvement. The potential benefits of using learning analytics and technology to augment medical training abound. To ensure that the ideals of this future for medical education are realized, educators should partner with trainees to build and implement new assessment systems. Coproduction of assessment systems by educators and trainees will help to ensure that new educational interventions are feasible and sustainable. In this paper, the authors provide a trainee perspective on 5 key areas that affect trainees in the next era of assessment: (1) precision education, (2) assessor education, (3) transparency in assessment development and implementation, (4) ongoing evaluation of the consequences of assessment, and (5) patient care data as sources of education outcomes.As precision education is developed, it is critical that trainees understand how their educational data are collected, stored, and ultimately utilized for educational outcomes. Since assessors play a key role in generating assessment data, it is important that they are prepared to give high-quality assessments and are continuously evaluated on their abilities. Transparency in the development and implementation of assessments requires communicating how assessments are created, the evidence behind them, and their intended uses. Furthermore, ongoing evaluation of the intended and unintended consequences that new assessments have on trainees should be conducted and communicated to trainees. Finally, trainees should participate in determining what patient care data are used to inform educational outcomes. The authors believe that trainee coproduction is critical to building stronger assessment systems that utilize evidence-based educational theories for improved learning and ultimately better patient care.

    Abstract Breast cancer relapse remains a common cause of morbidity and mortality in patients who undergo initial treatment with surgery and with or without concurrent chemotherapy or radiation. Relapse rates remain high within the first decade after initial treatment, after which the risk of relapse decreases. While common within the first year of breast cancer diagnosis, pleural metastasis with malignant pleural effusion (MPE) after 10-12 years of a disease-free period is rare. Here, we present two uncommon cases of delayed breast cancer relapses with pleural metastasis, which caused MPEs.

    Abstract Introduction: Intensive monitoring methods are used in pharmacovigilance for prescription medicines but have not yet been implemented for natural health products (NHPs).
    Objectives: Our objective was to assess feasibility issues with a new 'purchase event' intensive monitoring method for pharmacovigilance of NHPs, including pharmacy and NHP purchaser recruitment rates, collection of NHP purchaser key patient identifier information for data linkage and quality and completeness of data.
    Methods: For the Ginkgo study, 213 community pharmacies in the Auckland (Aotearoa New Zealand) District Health Board area were invited to participate. Staff in participating pharmacies (n = 3 [1.4%]) recorded ginkgo product sales and gave purchasers a study invitation card (October 2015-January 2016). Ginkgo purchaser participants were emailed links to web-based baseline and follow-up questionnaires about adverse events occurring during/after taking ginkgo. Participating pharmacists and consumers were invited to provide qualitative feedback about the study. For the NHP-Lite study, all NHPs were included for monitoring. Community pharmacies in the Green Cross Health network were invited to participate. Participating pharmacy staff gave all NHP purchasers a study invitation card over a 2-week period (May 2016). NHP purchaser participants were emailed links to web-based baseline, follow-up and feedback questionnaires.
    Results: Few community pharmacists (Ginkgo study, n = 3; NHP-Lite study, n = 18) and NHP purchasers (Ginkgo study, n = 0; NHP-Lite study, n = 4) participated. Pharmacists (Ginkgo study, 3/3; NHP-Lite study, 11/18) described several reasons for participating and suggested ways to increase consumer recruitment, including simplifying study procedures.
    Conclusions: These web-based, purchase event, intensive monitoring studies, with cohorts built through NHP purchases in pharmacies, identified substantial issues with recruiting pharmacists/pharmacies and NHP purchasers that, at present, render such studies unfeasible. Future studies need to consider other methods of recruiting NHP purchasers and develop a simple method for recording NHP purchases.

    Abstract Abstract Background Virtual reality training (VRT) uses computer software to track a user’s movements and allow him or her to interact with a game presented on a television screen. VRT is increasingly being used for the rehabilitation of arm function, balance and walking after stroke. Patients often require ongoing therapy post discharge from inpatient rehabilitation. Outpatient therapy may be limited or inaccessible due to waiting lists, transportation issues, distance etc.; therefore, home-based VRT could provide the required therapy in a more convenient and accessible setting. The objectives of this parallel randomized feasibility trial are to determine (1) the feasibility of using VRT in the home post stroke and (2) the feasibility of a battery of quantitative and qualitative outcome measures of stroke recovery. Methods Forty patients who can stand for at least 2 min and are soon to be discharged from inpatient or outpatient rehabilitation post stroke are being recruited in Ottawa, Canada and being randomized to control and experimental groups. Participants in the experimental group use home-based VRT to do rehabilitative exercises for standing balance, stepping, reaching, strengthening and gentle aerobic fitness. Control group participants use an iPad with apps selected to rehabilitate cognition, hand fine motor skills and visual tracking/scanning. Both groups are instructed to perform 30 min of exercise 5 days a week for 6 weeks. VRT intensity and difficulty are monitored and adjusted remotely. Weekly telephone contact is made with all participants. Ability to recruit participants, ability to handle the technology and learn the activities, compliance, safety, enjoyment, perceived efficacy and cost of program delivery will be assessed. A battery of assessments of standing balance, gait and community integration will be assessed for feasibility of completion within this population and potential for improvement following the intervention. Effect sizes will be calculated. Discussion The results of this study ...

    Abstract Asians as a group comprise > 60% the world’s population. There is an incredible amount of diversity in Asian and admixed populations that has not been addressed in a pharmacogenetic context. The known pharmacogenetic differences in Asian subgroups generally represent previously known variants that are present at much lower or higher frequencies in Asians compared with other populations. In this review we summarize the main drugs and known genes that appear to have differences in their pharmacogenetic properties in certain Asian populations. Evidence‐based guidelines and summary statistics from the US Food and Drug Administration and the Clinical Pharmacogenetics Implementation Consortium were analyzed for ethnic differences in outcomes. Implicated drugs included commonly prescribed drugs such as warfarin, clopidogrel, carbamazepine, and allopurinol. The majority of these associations are due to Asians more commonly being poor metabolizers of cytochrome P450 (CYP) 2C19 and carriers of the human leukocyte antigen (HLA)‐B*15:02 allele. The relative risk increase was shown to vary between genes and drugs, but could be > 100‐fold higher in Asians. Specifically, there was a 172‐fold increased risk of Stevens‒Johnson syndrome and toxic epidermal necrolysis with carbamazepine use among HLA‐B*15:02 carriers. The effects ranged from relatively benign reactions such as reduced drug efficacy to severe cutaneous skin reactions. These reactions are severe and prevalent enough to warrant pharmacogenetic testing and appropriate changes in dose and medication choice for at‐risk populations. Further studies should be done on Asian cohorts to more fully understand pharmacogenetic variants in these populations and to clarify how such differences may influence drug response.

    New insights from an inducible deletion model

    Abstract Metabolic conditions such as obesity, insulin resistance and glucose intolerance are frequently associated with impairments in skeletal muscle function and metabolism. This is often linked to dysregulation of homeostatic pathways including an increase in reactive oxygen species (ROS) and oxidative stress. One of the main sites of ROS production is the mitochondria, where the flux of substrates through the electron transport chain (ETC) can result in the generation of oxygen free radicals. Fortunately, several mechanisms exist to buffer bursts of intracellular ROS and peroxide production, including the enzymes Catalase, Glutathione Peroxidase and Superoxide Dismutase (SOD). Of the latter, there are two intracellular isoforms; SOD1 which is mostly cytoplasmic, and SOD2 which is found exclusively in the mitochondria. Developmental and chronic loss of these enzymes has been linked to disease in several studies, however the temporal effects of these disturbances remain largely unexplored. Here, we induced a post-developmental (8-week old mice) deletion of SOD2 in skeletal muscle (SOD2-iMKO) and demonstrate that 16 weeks of SOD2 deletion leads to no major impairment in whole body metabolism, despite these mice displaying alterations in aspects of mitochondrial abundance and voluntary ambulatory movement. This is likely partly explained by the suggestive data that a compensatory response may exist from other redox enzymes, including catalase and glutathione peroxidases. Nevertheless, we demonstrated that inducible SOD2 deletion impacts on specific aspects of muscle lipid metabolism, including the abundance of phospholipids and phosphatidic acid (PA), the latter being a key intermediate in several cellular signaling pathways. Thus, our findings suggest that post-developmental deletion of SOD2 induces a more subtle phenotype than previous embryonic models have shown, allowing us to highlight a previously unrecognized link between SOD2, mitochondrial function and bioactive lipid species including PA.

    Abstract Aim: To evaluate the clinical outcomes and other impacts of brief therapy provided in a primary care setting by a clinical psychologist who was mainly employed in secondary mental health.
    Method: The outcomes of 23 primary care patients referred to a clinical psychologist were evaluated using the General Health Questionnaire (GHQ), the World Health Organisation Quality of Life (WHOQoL) scale, and the Beck Depression Inventory (BDI). A mixture of quantitative and qualitative data from patients and staff were analysed to identify other impacts of the intervention.
    Results: Large improvements in BDI, GHQ, and WHOQOL scores were found, with strong changes consistent with the targets of the intervention. Patients reported primary-based clinical psychology input was more convenient and many engaged who had resisted referral to secondary mental health services. Other benefits to the service, including improved primary-secondary service integration, improved primary management of mental health difficulties, and improved liaison with mental health specialists, were reported by primary health staff.
    Conclusion: Brief psychological interventions by a visiting clinical psychologist in a general practice setting had substantial benefits for the patients and for the practice. This project indicates the value of integrated psychological input consistent with recent moves to better primary-secondary integration in mental health care.

    Abstract Background: The last decade has seen the emergence of a new phenomenon in recreational substance use with the availability of herbal and synthetic, unregulated, psychoactive drugs in the market place; alongside this, international concern has developed in relation to their use and associated harms. New Zealand (NZ) was one of the first countries to experience this new phenomenon, with products containing chemicals of the piperazine group - mainly benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP). In 2008, the NZ Government prohibited these substances, but allowed a 6-month amnesty period for possession. Our study aimed to obtain a measure of change in BZP use over time.
    Methods: This study used a longitudinal, web-based survey, with data collected at two time points from the same participants. The first survey was carried out 3 months after BZP prohibition, and included retrospective questions for the 6 months preceding the survey. The second survey was conducted 9 months after prohibition and also included retrospective questions for the 6 months preceding the survey.
    Results: 273 sets of paired data were identified. The use of BZP party pills (p<0.0001) and legally available smokeable products (p=0.002) reduced over time. A majority of users of party pills obtained them from friends or from their own stockpiled supplies. The misuse of prescription drugs (p=0.02) increased over time, whereas statistically significant increases in stimulant or alcohol use were not noted.
    Conclusion: Following prohibition of piperazine-based party pills, we noted a significant reduction in the proportions of participants using them. The observed increase in the misuse of prescription medicines may relate to their perceived 'quality', or as being less 'illegal' than illicit drugs.
