Abstract
Tickborne diseases (TBDs) are increasingly prevalent in Illinois and the Upper Midwest region. People who work in occupations that require time outdoors in agricultural or natural settings, such as some Extension workers, are at risk of tick bites and TBDs. Additionally, Extension workers are often a primary source of information about ticks and TBDs in rural communities. However, there is limited information on the level of awareness about ticks and TBDs in the Extension community. The goals of this study were to sequentially i) determine the baseline awareness of Extension workers in Illinois about ticks and TBDs using a knowledge, attitudes, and practices (KAP) survey tool, ii) provide comprehensive training on ticks and TBDs to this demographic, and iii) measure the uptake of knowledge after the training intervention through a post-training survey. The study period was from June 2022 until May 2023. We received 233 pre-training and 93 paired post-training survey responses. Most survey respondents were Extension volunteers, identified as women, and were over 50 years old. Knowledge about ticks and TBDs varied. We identified several gaps in their current tick awareness, most importantly, in tick prevention measures, tick identification, and TBDs in general. TBD knowledge, attitude, and practice scores all significantly improved after training (p < 0.001), with a mean difference of 10.47, 1.49, and 2.64 points, respectively. Additionally, both Extension professionals (79.2 %) and Extension volunteers (66.7 %) were more likely to feel confident in engaging with their stakeholders on ticks and TBDs after participating in training. Poisson models revealed that higher attitude and practice scores and greater self-reported knowledge were the factors most significantly associated with higher TBD knowledge. We found that greater concern for ticks and TBD (attitudes) and adherence to science-based prevention and management methods (practices) were also associated with higher knowledge scores. To our knowledge, this is the first study in Illinois to capture Extension workers' awareness of ticks and TBDs. The results highlight Extension workers' interest in filling knowledge gaps through learning, and the importance of training Extension workers to disseminate reliable and updated information on ticks and TBDs to their constituents, a critical step in preventing TBDs.

Abstract
BACKGROUND AND OBJECTIVES It is not possible to fully establish the safety of a disease-modifying drug (DMD) for multiple sclerosis (MS) from randomized controlled trials as only very common adverse events occurring over the short-term can be captured, and the quality of reporting has been variable. We examined the relationship between the DMDs for MS and potential adverse events in a multiregion population-based study. METHODS We identified people with MS using linked administrative health data from 4 Canadian provinces. MS cases were followed from the most recent of first MS or related demyelinating disease event on January 1, 1996, until the earliest of emigration, death, or December 31, 2017. DMD exposure primarily comprised β-interferon, glatiramer acetate, natalizumab, fingolimod, dimethyl fumarate, teriflunomide, and alemtuzumab. We examined associations between DMD exposure and infection-related hospitalizations and physician visits using recurrent events proportional means models and between DMD exposure and 15 broad categories of incident adverse events using stratified multivariate Cox proportional hazard models. RESULTS We identified 35,894 people with MS. While virtually all DMDs were associated with a 42%-61% lower risk of infection-related hospitalizations, there was a modest increase in infection-related physician visits by 10%-33% for select DMDs. For incident adverse events, most elevated risks involved a second-generation DMD, with alemtuzumab's hazard of thyroid disorders being 19.42 (95% CI 9.29-36.51), hypertension 4.96 (95% CI 1.78-13.84), and cardiovascular disease 3.72 (95% CI 2.12-6.53). Natalizumab's highest risk was for cardiovascular disease (adjusted hazard ratio [aHR] 1.61; 95% CI 1.24-2.10). For the oral DMDs, fingolimod was associated with higher hazards of cerebrovascular (aHR 2.04; 95% CI 1.27-3.30) and ischemic heart diseases (aHR 1.64; 95% CI 1.10-2.44) and hypertension (aHR 1.73; 95% CI 1.30-2.31); teriflunomide with higher hazards of thyroid disorders (aHR 2.30; 95% CI 1.11-4.74), chronic liver disease (aHR 1.94; 95% CI 1.19-3.18), hypertension (aHR 1.76; 95% CI 1.32-2.37), and hyperlipidemia (aHR 1.61; 95% CI 1.07-2.44); and from complementary analyses (in 1 province), dimethyl fumarate with acute liver injury (aHR 6.55; 95% CI 1.96-21.87). DISCUSSION Our study provides an extensive safety profile of several different DMDs used to treat MS in the real-world setting. Our findings not only complement those observed in short-term clinical trials but also provide new insights that help inform the risk-benefit profile of the DMDs used to treat MS in clinical practice. The results of this study highlight the continued need for long-term, independent safety studies of the DMDs used to treat MS. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that for patients with MS, while DMD exposure reduces the risk of infection-related hospitalizations, there are increased risks of infection-related physician visits and incident adverse events for select DMDs.

Abstract
Introduction Neurological conditions account from more than half of Canadians requiring chronic care. Both physical activity and the development of a self-management skillset are critical components supporting individuals with chronic health conditions. "NeuroSask: Active and Connected" is a virtual chronic disease management program offering twice weekly neuro-physiotherapist directed "active" exercise sessions, followed by weekly knowledge-exchange "connect" sessions with invited guest experts. NeuroSask was launched April 2020 in response to the restricted services and supports for people with neurological conditions. The program aimed to provide seated physical activity, social interaction, and access to expertise in neurological conditions and neurorehabilitation. A program evaluation of NeuroSask was conducted to gain participants' perspectives. Methods All participants registered for the NeuroSask program were invited to complete optional online surveys (SurveyMonkey) circulated by email at 3 occasions post-program launch: 10 weeks, 1 year, and 2 years. Participants could complete any one or all of the surveys, at their discretion. The number of potential respondents changed dependent on the total number of participants registered for NeuroSask at the time the survey was circulated. Questions were co-designed by multi-stakeholder team members. Descriptive statistics were used for closed-ended questions and a reflexive thematic analysis was completed with coding conducted in NVivo 12 Plus for open-ended text. Results Response rates (participants/registrants) were as follows: 10-week survey 260/793, one year survey 326/1224, and 2-year survey 434/1989. 90% of participants reported being in either the age categories of 40-59 years or above 60 years. 75% of both survey respondents and program registrants were female. 70% of both survey respondents and program registrants reported a diagnosis of multiple sclerosis and 30% reported other neurological conditions. Survey respondents were from all ten Canadian provinces, with 45% reporting living outside of large cities. Respondents reported preferring online vs. in person format for this type of programming. Three main themes, and eight corresponding subthemes were identified highlighting the perceived impact and key components of the NeuroSask program: Theme 1 "together in a positive and encouraging environment" (subthemes 1a: connection, 1b: empowerment); Theme 2 "access to enthusiastic qualified leaders from home" (subthemes 2a: leader characteristics, 2b: accessibility, 2c: program logistics); Theme 3 "being able to enjoy everyday life" (subthemes 3a: symptom benefits and beyond, 3b: carry-over, 3c: keep going, please do not cancel). Conclusion NeuroSask is an example of an accessible and meaningful virtual approach to providing ongoing support for some individuals with neurological conditions. It was perceived as beneficial for fostering community and connection in a positive environment with perceived benefits extending beyond symptom management to participant reported improvements in function, daily life, and disease experience.

Abstract
Background Much remains unknown surrounding the disease-modifying drugs (DMDs) used to treat multiple sclerosis and infection-related healthcare use in the 'real-world' setting. We examined if DMD exposure was associated with altered infection-related healthcare use. Methods We assessed if DMD (versus no) exposure was associated with altered infection-related hospitalizations, physician claims, and prescriptions filled in British Columbia, Canada (1996-2017). Healthcare use was assessed using negative binomial and proportional means regression models, reported as sex-/age-/comorbidity-/calendar year-/socioeconomic-adjusted rate and hazard ratios [aRR, aHR], with 95% confidence intervals [CIs]). Findings We identified 19,360 multiple sclerosis cases (13,940/19,360; 72.0% women; mean age at study start = 44.5 standard deviation, SD = 13.3; mean follow-up = 11.7 [SD = 7.3] years). Relative to unexposed periods, exposure to any DMD was associated with a lower infection-related rate of physician claims (aRR = 0.88; 95% CI:0.85-0.92) and hazard of hospitalization (aHR = 0.64; 95% CI:0.56-0.73), and a higher rate of infection-related prescriptions (aRR = 1.14; 95% CI:1.08-1.20). Exposure to any injectable or oral DMD was associated with a lower infection-related rate of physician claims (injectable aRR = 0.88; 95% CI:0.84-0.92, oral aRR = 0.83; 95% CI:0.77-0.90) and hazard of hospitalization (injectable aHR = 0.65; 95% CI:0.56-0.75, oral aHR = 0.54; 95% CI:0.38-0.77), whereas intravenous DMD exposure was not (aRR = 0.99; 95% CI:0.86-1.14, aHR = 0.73; 95% CI:0.49-1.09). Exposure to any injectable or intravenous DMD was associated with a higher rate of infection-related prescriptions (injectable aRR = 1.15; 95% CI:1.08-1.22, intravenous = 1.34; 95% CI:1.15-1.56), whereas oral DMDs were not (aRR = 0.98; 95% CI:0.91-1.05). Interpretation DMD exposure for the treatment of MS was associated with differences in infection-related healthcare use. While infection-related hospitalizations and physician visits were lower, prescription fills were higher. How these differences in infection-related healthcare use affect outcomes in persons with multiple sclerosis warrants consideration.

Abstract
OBJECTIVE To investigate gastrointestinal (GI)-related physician visits and drug dispensations in the 5 years preceding a first recorded demyelinating event or multiple sclerosis (MS) onset. METHODS Using linked administrative and clinical data from British Columbia (1996-2013), Canada, we identified an administrative cohort via a validated algorithm (n = 6863), a clinical cohort diagnosed at a MS clinic (n = 966), and matched controls (administrative cohort: n = 31,865; clinical cohort: n = 4534). In each cohort, the 5 years before a first demyelinating event or MS symptom onset (i.e., index date) were examined. We compared rates of GI-related physician visits and risk of ≥1 GI-related dispensation between MS cases and controls using negative binomial and robust Poisson models. Sex differences were tested using interaction terms. RESULTS The administrative cohort MS cases had higher rates of physician visits related to gastritis and duodenitis (adjusted rate/risk ratio (aRR):1.42, 95% CI: 1.10-1.83) and diseases of the esophagus (aRR: 1.46, 95% CI: 1.06-2.02) prior to the index date. MS cases also had greater risk of at least one dispensation for several drug classes, including constipation-related (aRR: 1.82, 95% CI: 1.50-2.22), antiemetics/antinauseants (aRR: 1.64, 95% CI: 1.43-1.89), and propulsives (promotility drugs; aRR: 1.62, 95% CI: 1.47-1.79). Men had a disproportionally higher relative risk for propulsives than women (aRR: men = 2.32, 95% CI: 1.79-3.00; women = 1.54, 95% CI: 1.36-1.72). Several findings were similar in the smaller clinical cohort though none reached statistical significance. INTERPRETATION GI-related physician visits and drug dispensations were more common in the 5 years before the first demyelinating event versus matched controls. GI symptoms are a measurable feature of the prodromal or early phase of MS, with a sex difference evident.

Abstract
Necrotic enteritis (NE) continues to be a significant burden to the poultry industry, compounded by pressure to reduce antibiotic use. Researchers use NE-challenge models to study the infection biology of NE and as screening tools to develop potential novel interventions. Currently, data are limited comparing such models between research establishments, and few indicate which quantitative metrics provide the most accurate measure for determining the efficacy of interventions. We compared data from 10 independent NE-challenge trials incorporating six challenge models employed in four geographical regions to determine the extent of variability in bird responses and to determine, using principal component analysis (PCA), which variables discriminated most effectively between nonchallenged control (NC) and challenged control (CC) groups. Response variables related to growth performance (weight gain, feed intake, feed conversion), health (mortality, lesion scores, NE induction rate), and, in three trials only, gut integrity (tight junction protein claudin-1, claudin-2, and zonula occludens-1 expression, coccidia counts, and intestinal permeability [assessed by FITC-dextran assay]). Treatments included a CC, which varied between trials (for example, in Eimeria predisposition, Clostridium perfringens strain, and days of inoculation), and a NC. The degree of response to challenge in CC birds varied significantly among models and trials. In all trials, lesion scores 1 to 4 days postchallenge were increased in CC vs. NC birds and varied both within and among models (by 0.29-1.17 points and 0.05-2.50 points, respectively). In addition, NE-related mortality at day 28 was increased in CC vs. NC, both within and among models (by 1.79%-4.72% and 0.02%-16.70%, respectively), and final (day 35 or 42) body weight was reduced by 3.9%-14.4% and overall FCR increased by up to 27% across trials (P , 0.05). A PCA on the combined dataset including only performance indicators failed to adequately differentiate NC and CC groups. However, the combination of performance and gut integrity variables and standardization of data by trial and phase achieved greater resolution between groups. This indicated that the inclusion of both types of variables in future NE-challenge studies would enable the generation of more robust predictions about intervention efficacy from different types of infection models. A final PCA based on a subset of key indicator variables, including body weight, feed intake, feed conversion ratio, mortality, and lesion score, achieved a good level of separation between NC and CC status of birds and could, with further research, be a useful supplement to existing approaches for assessing and predicting the NE status of birds in the field.

Abstract
Little is known about disease-modifying drug (DMD) initiation by immigrants with multiple sclerosis (MS) in countries with universal health coverage. We assessed the association between immigration status and DMD use within 5-years after the first MS-related healthcare encounter. Using health administrative data, we identified MS cases in British Columbia (BC), Canada. The index date was the first MS-related healthcare encounter (MS/demyelinating disease-related diagnosis or DMD prescription filled), and ranged from 01/January/1996 to 31/December/2012. Those included were ≥ 18 years old, BC residents for ≥ 1-year pre- and ≥ 5-years post-index date. Persons becoming permanent residents 1985-2012 were defined as immigrants, all others were long-term residents. The association between immigration status and any DMD prescription filled within 5-years post-index date (with the latest study end date being 31/December/2017) was assessed using logistic regression, reported as adjusted odds ratios (aORs) with 95% confidence intervals (CIs). We identified 8762 MS cases (522 were immigrants). Among immigrants of lower SES, odds of filling any DMD prescription were reduced, whereas they did not differ between immigrants and long-term residents across SES quintiles (aOR 0.96; 95%CI 0.78-1.19). Overall use (odds) of a first DMD within 5 years after the first MS-related encounter was associated with immigration status.

Abstract
BACKGROUND AND OBJECTIVES Psychiatric morbidity is common after a multiple sclerosis (MS) diagnosis. However, little is known about psychiatric comorbidity during the prodromal phase (before MS onset). To compare the prevalence and relative burden of psychiatric morbidity in individuals with MS with matched controls before MS onset. METHODS Using linked administrative and clinical data from British Columbia, Canada, we identified cases with MS through a validated algorithm or from neurologist-diagnosed MS clinic attendees. Cases were matched by age, sex, and geographical location with up to 5 general population controls. We identified psychiatric morbidity through a validated definition and determined its prevalence in cases/controls in the 5 years before the first demyelinating claim of cases with MS ("administrative cohort") or symptom onset ("clinical cohort") and estimated case/control prevalence ratios with 95% CIs. We also compared the yearly number of physician visits for psychiatric morbidity, visits to psychiatrists, psychiatric-related admissions, and psychotropic dispensations pre-MS onset in cases/controls regardless of whether psychiatric morbidity algorithm was fulfilled using negative binomial regression fitted through generalized estimating equations; results were reported as adjusted rate ratios with 95% CIs. We assessed yearly trends through interaction terms between cases/controls and each year pre-MS onset. RESULTS The administrative cohort comprised 6,863/31,865 cases/controls; the clinical cohort comprised 966/4,534 cases/controls. Over the entire 5-year period pre-MS onset, 28.0% (1,920/6,863) of cases and 14.9% (4,738/31,865) of controls (administrative cohort) had psychiatric morbidity, as did 22.0% (213/966) of clinical cases and 14.1% (638/4,534) controls. Psychiatric morbidity prevalence ratios ranged from 1.58; 95% CI 1.38-1.81 (clinical cohort) to 1.91; 95% CI 1.83-2.00 (administrative cohort). In the administrative cohort, health care use was higher for cases in each year pre-MS onset (all 95% CIs >1); physician visits were 78% higher in year 5 pre-MS onset and 124% 1 year before; visits to psychiatrists were 132% higher in year 5 and 146% in year 1; hospitalizations were 129% higher in year 5 and 197% in year 1; and prescription dispensations were 72% higher in year 5 and 100% in year 1. Results were not significant in the clinical cohort. DISCUSSION Psychiatric morbidity represents a significant burden before MS onset and may be a feature of the MS prodrome.

Abstract
PURPOSE/OBJECTIVE(S) Adjuvant radiation therapy (RT) for early breast cancer is a highly effective treatment option. However, the multitude of available techniques backed by strong clinical evidence can result in a lack of consistency in treatment approaches, even within a single healthcare organization. This presents challenges for both providers and patients in making informed decisions. To address this issue, our radiation department, which serves a large and diverse health system, developed a clinical algorithm for adjuvant RT for breast cancer. This algorithm was created to enhance the quality and standardization of care delivered across our network. MATERIALS/METHODS A modified Delphi technique was used. A panel of eight experienced breast radiation oncologists from our institution was assembled. The panel first identified the common clinical scenarios encountered in treating patients with adjuvant breast RT, and then made recommendations for the primary and alternative approaches for each scenario. NCCN guidelines, ASTRO executive summaries, and published national and international randomized trials were used for reference. In case of disagreements, the final recommendation was reached through a majority vote. The draft algorithm was also shared with medical oncologists, surgeons, and patient advocates to gather their input prior to final approval by the expert panel. RESULTS Consensus was reached for three broad clinical scenarios for patients who have undergone lumpectomy or mastectomy: Ductal Carcinoma in Situ (DCIS), Invasive Cancer Node Negative (ICN0), and Invasive Cancer Node Positive (ICN+). The panel agreed subdivision of the scenarios into three risk groups (low, intermediate, and high) and three age groups, based on guidelines and consensus statements. For DCIS patients, size, grade, margin status, hormone receptor status, and tumor focality were used for further stratification. For ICN0 patients, HER2 receptor status and lymphovascular space invasion were also included. For ICN+ patients, nodal status (negative versus 1-3 positive nodes versus more than 3 positive nodes) was used for stratification. Additionally, DCIS and ICN0 patients were further divided into age groups. The panel reached consensus recommendations for RT, including whole breast RT, partial breast RT, chest wall RT, regional nodal irradiation, or omission of RT for each sub-group. Clinical trial enrollment was also recommended where appropriate. CONCLUSION A breast cancer adjuvant RT algorithm was developed with the aim of standardizing care for patients with breast cancer. Implementation is expected to standardize treatment recommendations in our health system and to streamline the shared decision-making process with patients.

Abstract
BACKGROUND The global prevalence of peripartum mental illness is 20%, though estimates have increased since the start of the COVID-19 pandemic. Chronic illnesses affect one in five pregnancies and may be associated with higher rates of peripartum mental illness. Though pharmacists are well-positioned to facilitate appropriate and timely care of co-occurring mental and physical health conditions during this period, little is understood regarding their potential roles. OBJECTIVES To understand the current evidence examining the role of pharmacists to improve the outcomes of women with peripartum mental illness, with and without chronic illness. METHODS A scoping review was performed with assistance from an interdisciplinary team following the Joanna Briggs Institute framework. MEDLINE, Embase, PsychNet and International Pharmaceutical Abstracts databases were searched. English-language articles (published up to May 30, 2022) were screened and assessed for eligibility, and data were charted to collate results, by dual independent reviewers. RESULTS The search strategy produced 922 articles. After screening, 12 articles were included (5 narrative reviews, 7 primary research). There was limited discussion or empirical data regarding specific interventions (screening, counseling), opportunities (accessibility, managing stigma, forming trusting relationships and building rapport with patients) or barriers (lack of privacy, time constraints, adequate remuneration, training) associated with an expanded role of pharmacists in peripartum mental health care. The clinical complexity arising from co-occurring mental health and chronic illnesses was not explored, other than a small pilot study involving pharmacists screening for depression among pregnant women with diabetes. CONCLUSIONS This review highlights the limited evidence available on the explicit role of pharmacists in supporting women with peripartum mental illness, including those with comorbidity. More research, including pharmacists as study participants, is required to fully understand the potential roles, barriers, and facilitators of integrating pharmacists into peripartum mental healthcare to improve the outcomes of women in the peripartum period.

Abstract
Introduction Surgical stabilization of rib fractures (SSRF) is an emerging therapy for the treatment of patients with traumatic rib fractures. Despite the demonstrated benefits of SSRF, there remains a paucity of literature regarding the complications from SSRF, especially those related to hardware infection. Currently, literature quotes hardware infection rates as high as 4%. We hypothesize that the hardware infection rate is much lower than currently published. Methods This is an IRB-approved, four-year multicenter descriptive review of prospectively collected data from January 2016 to June 2022. All patients undergoing SSRF were included in the study. Exclusion criteria included those patients less that 18 years of age. Basic demographics were obtained: age, gender, Injury Severity Score (ISS), Abbreviate Injury Scale-chest (AIS-chest), flail chest (yes/no), delayed SSRF more than two weeks (yes/no), number of patients with a pre-SSRF chest tube, and number of ribs fixated. Primary outcome was hardware infection. Secondary outcomes included mortality rate and hospital length of stay (HLOS). Basic descriptive statistics were utilized for analysis. Results A total of 453 patients met criteria for inclusion in the study. Mean age was 63 ± 15.2 years and 71% were male. Mean ISS was 17.3 ± 8.5 with a mean AIS-chest of 3.2 ± 0.5. Flail chest (three consecutive ribs with two or more fractures on each rib) accounted for 32% of patients. Forty-two patients (9.3%) underwent delayed SSRF. The average number of ribs stabilized was 4.75 ± 0.71. When analyzing the primary outcome, only two patients (0.4%) developed a hardware infection requiring reoperation to remove the plates. Overall HLOS was 10.5 ± 6.8 days. Five patients suffered a mortality (1.1%), all five with ISS scores higher than 15 suggesting significant polytrauma. Conclusion This is the largest case series to date examining SSRF hardware infection. The incidence of SSRF hardware infection is very low (<0.5%), much less than quoted in current literature. Overall, SSRF is a safe procedure with low morbidity and mortality.

Abstract
BACKGROUND The relationship between socioeconomic status (SES) and mortality among persons with multiple sclerosis (PwMS) is poorly understood. OBJECTIVE To investigate the association between SES and mortality risk in PwMS. METHODS From health-administrative data, we identified 12,126 incident MS cases with a first demyelinating event (MS 'onset') occurring between 1994 and 2017. Cox proportional hazard model assessed the association between socioeconomic status quintiles (SES-Qs) at MS onset and all-cause mortality. RESULTS Lower SES-Qs were associated with higher mortality risk; adjusted hazard ratios: SES-Q1 (most deprived) =1.61 (95% confidence interval (CI) = 1.36-1.91); SES-Q2 = 1.26 (95% CI = 1.05-1.50); SES-Q3 = 1.22 (95% CI = 1.02-1.46); SES-Q4 = 1.13 (95% CI = 0.94-1.35) versus SES-Q5 (least deprived). CONCLUSION A lower SES was associated with higher mortality risk in PwMS.

Abstract
BACKGROUND The UK High-Consequence Infectious Diseases (HCID) Network of high-level isolation units provides care for patients with contact- or airborne-transmissible highly infectious and highly dangerous diseases. In most HCID units, the healthcare workers (HCWs) wear personal protective equipment (PPE) ensembles incorporating a powered air-purifying respirator (PAPR) for head and respiratory protection. Some PAPRs have components worn outside/over other PPE, necessitating decontamination of re-usable elements. Two alternative PAPRs, with all re-usable elements worn under PPE, were trialled in this study. AIM To undertake scenario-based testing of PAPRs and PPE to determine usability, comfort and ability to remove contaminated PPE without personal cross-contamination. METHODS Trained healthcare volunteers (N=20) wearing PAPR/PPE ensembles were sprayed with ultraviolet fluorescent markers. They undertook exercises to mimic patient care, and subsequently, after doffing the contaminated PPE following an established protocol, any personal cross-contamination was visualized under ultraviolet light. Participants also completed a questionnaire to gauge how comfortable they found the PPE. FINDINGS AND CONCLUSIONS The ensembles were tested under extreme 'worst case scenario' conditions, augmented by physical and manual dexterity tests. Participating volunteers considered the exercise to be beneficial in terms of training and PPE evaluation. Data obtained, including feedback from questionnaires and doffing buddy observations, supported evidence-based decisions on the PAPR/PPE ensemble to be adopted by the HCID Network. One cross-contamination event was recorded in the ensemble chosen; this could be attributed to doffing error, and could therefore be eliminated with further practice.

Abstract
Background and objectives Little is known of the potential sex and age differences in the MS prodrome. We investigated sex and age differences in healthcare utilization during the MS prodrome. Methods This was a population-based matched cohort study linking administrative and clinical data from British Columbia, Canada (population = 5 million). MS cases in the 5 years preceding a first demyelinating event ("administrative cohort;" n = 6,863) or MS symptom onset ("clinical cohort;" n = 966) were compared to age-, sex- and geographically-matched controls (n = 31,865/4,534). Negative binomial and modified Poisson models were used to compare the rates of physician visits and hospitalizations per international classification of diseases chapter, and prescriptions filled per drug class, between MS cases and controls across sex and age-groups (< 30, 30-49, ≥50 years). Results In the administrative cohort, males with MS had a higher relative rate for genitourinary-related visits (males: adjusted Rate Ratio (aRR) = 1.65, females: aRR = 1.19, likelihood ratio test P = 0.02) and antivertigo prescriptions (males: aRR = 4.72, females: aRR = 3.01 P < 0.01). Injury and infection-related hospitalizations were relatively more frequent for ≥50-year-olds (injuries < 30/30-49/≥50: aRR = 1.16/1.39/2.12, P < 0.01; infections 30-49/≥50: aRR = 1.43/2.72, P = 0.03), while sensory-related visits and cardiovascular prescriptions were relatively more common in younger persons (sensory 30-49/≥50: aRR = 1.67/1.45, P = 0.03; cardiovascular < 30/30-49/≥50: aRR = 1.56/1.39/1.18, P < 0.01). General practitioner visits were relatively more frequent in males (males: aRR = 1.63, females: aRR = 1.40, P < 0.01) and ≥50-year-olds (< 30/≥50: aRR = 1.32/1.55, P = 0.02), while differences in ophthalmologist visits were disproportionally larger among younger persons, < 50-years-old (< 30/30-49/≥50: aRR = 2.25/2.20/1.55, P < 0.01). None of the sex and age-related differences in the smaller clinical cohort reached significance (P ≥ 0.05). Discussion Sex and age-specific differences in healthcare use were observed in the 5 years before MS onset. Findings demonstrate fundamental heterogeneity in the MS prodromal presentation.

Abstract
Abstract
Background
Late diagnosis of HIV remains a challenge and the construction workforce has several risk factors for HIV. In the Test@Work programme, we delivered HIV tests embedded within a general health check to construction workers, with high uptake and acceptability. Here, we report the experiences of construction managers and health professionals involved in Test@Work and explore the suitability of construction worksites as a venue for opt-in HIV testing.
Methods
Qualitative interviews (n = 24) were conducted with construction managers who facilitated events (n = 13), and HIV/health check delivery partners (n = 11) at 21 Test@Work events held on construction sites. Interviews explored experiences of events and views towards workplace HIV testing. Event exit questionnaires (n = 107) completed by delivery partners provided qualitative data identifying facilitators and barriers to effective delivery. Thematic analysis identified themes that were mapped against a socioecological framework (individual, interpersonal, organisational, industry, public health).
Results
Delivery partners reported high engagement of construction workers with workplace HIV testing, peer-to-peer encouragement for uptake, and value for accessibility of onsite testing. HIV professionals valued the opportunity to reach an untested population, many of whom had a poor understanding of their exposure to HIV risk. Managers valued the opportunity to offer workplace health checks to employees but some identified challenges with event planning, or provision of private facilities.
Conclusions
The construction sector is complex with a largely male workforce. Providing worksite HIV testing and education to an untested population who have poor knowledge about HIV risk helped to normalise testing, increase uptake, and reduce HIV stigma. However, there are practical barriers to testing in the construction environment. This has global implications for delivery of HIV testing in construction workplace settings.
Key messages
• Delivering workplace HIV testing as part of a general health check helps to normalise HIV testing and reduce HIV-related stigma.
• Workplace testing is convenient, accessible and reaches populations at risk for HIV, but there are some barriers to implementation of rapid tests on construction sites.

Abstract
BACKGROUND AND OBJECTIVES We examined the association between the disease-modifying drugs (DMDs) for multiple sclerosis (MS) and survival in a multiregion population-based study. METHODS We accessed multiple administrative health databases from 4 Canadian provinces. Persons with MS were identified and followed from the most recent of the first MS or demyelinating event or January 1, 1996 (index date), until death, emigration, or December 31, 2017. Association between the first-generation and second-generation DMDs and all-cause mortality was examined using stratified Cox proportional hazard models, reported as adjusted hazard ratios (aHRs). Timing of DMD initiation was explored, with findings reported at 2, 5, or 10 years postindex date, representing very early, early, or late initiation. RESULTS We identified 35,894 persons with MS; 72% were female. The mean age at index date was 44.5 years (SD = 13.6). The total person-years of follow-up while DMD-exposed was 89,180, and total person-years while unexposed was 342,217. Compared with no exposure, exposure to any DMD or to any first-generation DMD was associated with a 26% lower hazard of mortality (both aHRs 0.74; 95% CI 0.56-0.98), while any second-generation DMD exposure was associated with a 33% lower hazard (aHR 0.67; 95% CI 0.46-0.98). Earlier DMD initiation (beta-interferon or glatiramer acetate vs no exposure) was associated with a significant mortality effect (p < 0.05), while later initiation was not (95% CIs included 1). However, the survival advantage with earlier initiation diminished over time, no longer reaching statistical significance at 15 years postindex date. DISCUSSION Our study demonstrates an association between the DMDs for MS and improved survival in the real-world setting.

Abstract
Background Chronic non-cancer pain is common among older residents of long-term care (LTC) homes and often poorly recognized and treated. With heightened concerns regarding opioid prescribing in recent years, it is important to examine the current prevalence of opioid use and its association with resident characteristics to help identify those potentially at risk of medication harms as well as suboptimal pain management. Objectives The aims were to estimate the prevalence and correlates of opioid use among non-palliative LTC residents and explore variation in opioid prevalence and correlates across strata defined by pain frequency and intensity. Methods We conducted a population-based cross-sectional study of all older (aged > 65 years) LTC residents (excluding those with cancer or receiving palliative care) in Ontario, Canada during 2018–2019. Health administrative databases were linked with standardized clinical assessment data to ascertain residents’ health and pain characteristics and their opioid and other medication use. Modified Poisson regression models estimated unadjusted and adjusted associations between residents’ characteristics and opioid use, overall and across strata capturing pain frequency and intensity. Results Among 75,020 eligible residents (mean age 85.1 years; 70% female), the prevalence of opioid use was 18.5% and pain was 29.4%. Opioid use ranged from 12.2% for residents with no current pain to 55.7% for those with severe pain. In adjusted models, residents newly admitted to LTC (adjusted risk ratio [aRR] = 0.60, 95% confidence interval [CI] 0.57–0.62) and with moderate to severe cognitive impairment (aRR = 0.69, 95% CI 0.66–0.72) or dementia (aRR = 0.76, 95% CI 0.74–0.79) were significantly less likely to receive an opioid, whereas residents with select conditions (e.g., arthritis, aRR = 1.37, 95% CI 1.32–1.41) and concurrently using gabapentinoids (aRR = 1.80, 95% CI 1.74–1.86), benzodiazepines (aRR = 1.33, 95% CI 1.28–1.38), or antidepressants (aRR = 1.31, 95% CI 1.27–1.35) were significantly more likely to receive an opioid. The associations observed for residents newly admitted, with dementia, and concurrently using gabapentinoids, benzodiazepines, or antidepressants were largely consistent across all pain strata. Conclusions Our findings describe resident sub-groups at potentially higher risk of adverse health outcomes in relation to both opioid use and non-use. LTC clinical and policy changes informed by research are required to ensure the appropriate recognition and management of non-cancer pain in this setting.

Abstract
The genera Paramoeba and Neoparamoeba (Amoebozoa, Dactylopodida, Paramoebidae) include well-known opportunistic pathogens associated with fish (N. peruans; amoebic gill disease), lobsters, molluscs and sea urchins, but only rarely with crabs (grey crab disease of blue crabs). Following reports of elevated post-capture mortality in edible crabs Cancer pagurus captured from a site within the English Channel fishery in the UK, a novel disease (amoebic crab disease, ACD) was detected in significant proportions of the catch. We present histopathological, transmission electron microscopy and molecular phylogenetic data, showing that this disease is defined by colonization of haemolymph, connective tissues and fixed phagocytes by amoeboid cells, leading to tissue destruction and presumably death in severely diseased hosts. The pathology was strongly associated with a novel amoeba with a phylogenetic position on 18S rRNA gene trees robustly sister to Janickina pigmentifera (which groups within the current circumscription of Paramoeba/Neoparamoeba), herein described as Janickina feisti n. sp. We provide evidence that J. feisti is associated with ACD in 50% of C. pagurus sampled from the mortality event. A diversity of other paramoebid sequence types, clustering with known radiations of N. pemaquidensis and N. aestuarina and a novel N. aestuarina sequence type, was detected by PCR in most of the crabs investigated, but their detection was much less strongly associated with clinical signs of disease. The discovery of ACD in edible crabs from the UK is discussed relative to published historical health surveys for this species.

Abstract

Type of funding sources: Foundation. Main funding source(s): The Burdett Trust for Nursing
Background
The COVID-19 pandemic affected health care systems profoundly. Inherited cardiac condition (ICC) specialist nurses were redeployed to intensive care or acute settings which either left services with no nurse or a single nurse manning a normally busy service (Bueser 2020). An exponential rise in patients reaching out to patient support charities was seen (Charity Today 2020) and at the peak of the pandemic, nurses based at an ICC charity dealt with 599 inquiries which was a 328% increase in activity. The toll on the mental health of nurses during the pandemic is well documented and programmes have been suggested to address this which includes peer support and psychological support by clinical psychologists
Purpose
The aim was to develop and strengthen collaborations between ICC specialist nurses in a tertiary hospital and those working in the community charity sector; and provide peer and psychological support to enable consistent high quality patient care.
Methods
The project was based on Wenger’s (1999) Communities of Practice (COP) framework model of situational learning, collaboration among peers, working to a common purpose. To develop the counselling aspect, a psychotherapist led a scoping exercise with the group. The 4Rs Skilled Helper Programme (SHP) of reflective learning, supervision and continuing professional development was then adapted as a bespoke programme - combining 30 hours of formal counselling, communication and reflective learning skills with equal attention to the normative, formative and restorative components of support and development needed to ensure practitioner health and wellbeing and the safety and quality of patient care
Results
Nine ICC nurses from a tertiary hospital and 3 from the charity sector participated in the project. Nine nurses undertook the tailored 4RS SHP course, adapting Egan's 3 stage problem-solving, decision-making and opportunity development framework as the vehicle for personalised, psychosocial, time-sensitive decision-making and informed consent for patients, and for the identification of support and development strategies that represent the 'best fit' for both clients and practitioners in their particular social and organisational circumstances. Counselling supervision is ongoing on a whole group, team and individual basis and provides opportunities to discuss collaborations, gain support for challenging clinical cases and work situations; and promoting psychological well-being.
Conclusions
The COP established through this project alongside the development of a bespoke counselling course and psychological supervision is an exemplar of how nurses can be empowered to continue to provide excellent care despite challenging circumstances. The 4RS SHP course also specifically addresses the competency needs for ICC nurses as move towards a genomics-driven, personalised health care delivery model.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BackgroundContextual factors (CFs) related to the patient, healthcare practitioners, and their therapeutic relationship are integral to the overall treatment effect of any given intervention (1). In osteoarthritis (OA), around 75% of the treatment effect is directly attributable to CFs (2). Identifying and understanding the role of CFs may encourage healthcare practitioners to develop and enhance the contextual aspects of care.ObjectivesTo explore and understand the experience and perspectives of patients and health practitioners regarding CFs in consultations for OA.MethodsA systematic search was conducted between March 15 and May 18, 2020, on the following databases: MEDLINE via Ovid, EMBASE, AMED, PsycINFO and CINAHL. The search for unpublished studies included ProQuest Dissertations and Google Scholar. The search was not limited to any language or publication year. The Joanna Briggs Institute (JBI) methodology for quality assessment, study selection, data extraction and synthesis were used. Findings were assessed for credibility, categorised based on similarity in meaning and subjected to a meta-aggregation. The ConQual approach was used to assess the confidence of the synthesised findings (3).ResultsOf 1808 records generated from the systematic search of databases and grey literature, eight studies were included in the meta-aggregation (Figure 1). All included papers were moderate to high quality based on the JBI qualitative critical appraisal tool. Meta-aggregation generated three synthesised findings. According to the ConQual criteria, all the synthesised findings’ level of evidence was rated as moderate (Table 1). The key, potentially modifiable, factors identified were positive communication; clear and relevant information provided by the health practitioner; patient expectation concerning their outcome and the consultation experience; sufficient consultation time; and easy access to consultations.Table 1.ConQual summary of findingsSynthesized findingType of researchDependabilityCredibilityConQual scoreI.

Abstract
Introduction Clients with Eating Disorders may be treated as inpatients (IP), day hospital (DH) or community patients (Ambu). The ITAMITED study is following to treatment termination (or end of October 2025) all new clients with EDs presenting between November 2017 and October 2020 to eight centres in Spain. Objectives To describe to what extent initial care levels (IP, DH, Ambu) are associated with gender, age, social relationships, ED diagnosis Body Mass Index (BMI) and baseline medication. Methods The study is exploratory/descriptive, practice-based evidence (PBE). Consecutive new clients were approached for participation. Inclusion criteria were a diagnosis of an ED and opting in to treatment. Results The only variables not showing a statistically significant relationship with level were gender (no relationship), diagnosis of bulimia and use of prescribed psychostimulant medication (which was rare). OP care was associated with older age which did not discriminate between DH and IP. Similarly, being in a relationship was associated with OP care but didn’t differentiate between DH and OP. Relationships with ED diagnosis other than AN type I were complex but significant. Relationships with AN type I, BMI and being on antipsychotics, antidepressants, anxiolytics, mood stabilisers and a catch-all category of all other medication all showed an ordered relationship IP > DH > Ambu. The most powerful relationships were with BMI and diagnosis of AN type I. ![]()
Conclusions
Initial level of care is associated with many factors and strongly with many of them. This will complicate the analyses of trajectories of change but reflects the heterogeneity of this client group. Disclosure

Abstract
Introduction A major revolution in psychiatry since the late 20th and early 21st Century has sought to put the individual client at the heart of intervention, promoting shared decision making. Increasing use of patient reported outcome measures (PROMs) to evaluate interventions and even steer therapies (“power assisted steering for psychotherapy”, Evans 2012) appears congruent with this. But is caution needed interpreting PROMS where self-perception distortions form a core part of the client’s problem? Eating disorders are a paradigmatic test. Objectives To see if PROM scores at initial presentation at services for ED seemed congruent with help-seeking. We report CORE-Outcome scores here. Methods Inclusion criteria were a diagnosis of an ED and opting in to treatment. Consecutive new clients at all the centres were approached for participation. Scores distributions were analysed to see if numbers of low scores, “non-clinical range” scores seemed congruent with help-seeking. Results 18% of the participants who completed the CORE-OM at baseline had a score below the Clinically Significant Change (CSC) cutting point. Though the rate was higher in participants with an Anorexia type I diagnosis (22.6%) than those with other ED diagnoses (15.8%): in the expected direction, the difference was narrowly non-significant (chi-squared = 3.5, d.f. = 1, p = .06). Scores did relate to treatment level. ![]()
Conclusions The predicted elevated rate of non-clinical baseline scores in the AN1 group was narrowly non-significant but the rate of 18% non-clinical scores in a help-seeking population raises a cautionary message about interpretation of change from initially low scores.

Abstract
We described emergency department (ED) visits (all visits and infection-related)
by persons with multiple sclerosis (MS) in British Columbia, Canada (1 April
2012 to 31 December 2017). We identified 15,350 MS cases using health
administrative data; 73.4% were women, averaging 51.4 years at study entry. Over
4.9 years of follow-up (mean), 56.0% of MS cases visited an ED (mean = 0.6
visits/person/year; total = 37,072 visits). A diagnosis was documented for
25,698 (69.3%) ED visits, and 18.4% (4725/25,698) were infection-related.
Inpatient admissions were reported for 20.4% (5238/25,698) of all and 29.2%
(1380/4725) of infection-related ED visits. Findings suggest that the ED plays a
substantial role in MS healthcare and infection management.

Abstract
INTRODUCTION Surgical stabilization of rib fractures (SSRF) has been gaining popularity for the treatment of rib fractures. Limited literature exists regarding the long-term effects of SSRF versus non-operative (NO) intervention. The goal of this study is to better understand these long-term effects, hypothesizing SSRF patients have better outcomes. METHODS IRB approved survey study at our Level I trauma center. Patients suffering rib fractures from 1/2017 through 1/2019 were surveyed via phone call and asked five questions. Basic demographics obtained. The five survey questions asked: "Are you still experiencing pain from your rib fractures?"; "If yes, how would you rate your pain 1-10?"; "Are you back to your baseline activity level?"; "If no, is this related to your rib fractures?"; "Do you feel your rib fractures moving/clicking?" Paired t test, Chi square, and median tests were utilized. Significance was set at p < 0.05. RESULTS 527 patients were called with 228 unsuccessfully reached. 47 refused to participate. 252 patients (47.8%) participated in the survey; 78 SSRF and 174 NO. Age and gender were similar between cohorts. Majority of patients suffered blunt trauma. No significant difference between ISS; 15 SSRF vs 14 NO. SSRF patients had worse chest trauma with median chest AIS of 3 (IQR 3-4) vs 3 (IQR 3-3) for NO (p < 0.001). Response to survey questions revealed similar incidences of pain between SSRF and NO cohorts (28.2% vs 27.6%; p = 0.939), however decreased pain scores for SSRF group (2 vs 4; p = 0.006). Return to baseline activity was better for the SSRF group (75.6% vs 56.3%; p = 0.143) and the incidence of rib fractures being the reason for patients not returning to baseline was decreased (26.3% vs 44.7%; p = 0.380). Lastly, SSRF resulted in significantly less movement of rib fractures (3.8% vs 13.8%; p = 0.031). CONCLUSION Patients who undergo SSRF show significant long-term improvements in pain scores and better return to baseline function with less overall issues from their rib fractures compared to those managed non-operatively.

Abstract
Background Evidence regarding the efficacy or effectiveness of the disease-modifying drugs (DMDs) in the older multiple sclerosis (MS) population is scarce. This has contributed to a lack of evidence-based treatment recommendations for the ageing MS population in practice guidelines. We examined the relationship between age (<55 and ≥55 years), DMD exposure and health service use in the MS population. Methods We conducted a population-based observational study using linked administrative health data from British Columbia, Canada. We selected all persons with MS and followed from the most recent of their first MS or demyelinating event, 18th birthday or 01-January-1996 (index date) until the earliest of emigration, death or 31-December-2017 (study end). We assessed DMD exposure status over time, initially as any versus no DMD, then by generation (first or second) and finally by each individual DMD. Age-specific analyses were conducted with all-cause hospitalizations and number of physician visits assessed using proportional means model and negative binomial regression with generalized estimating equations. Results We included 19,360 persons with MS (72% were women); 10,741/19,360 (56%) had ever reached their 55th birthday. Person-years of follow-up whilst aged <55 was 132,283, and 93,594 whilst aged ≥55. Any DMD, versus no DMD in the <55-year-olds was associated with a 23% lower hazard of hospitalization (adjusted hazard ratio, aHR0.77; 95%CI 0.72-0.82), but not in the ≥55-year-olds (aHR0.95; 95%CI 0.87-1.04). Similar patterns were observed for the first and second generation DMDs. Exposure to any (versus no) DMD was not associated with rates of physician visits in either age group (<55 years: adjusted rate ratio, aRR1.02; 95%CI 1.00-1.04 and ≥55 years: aRR1.00; 95%CI 0.96-1.03), but variation in aRR was observed across the individual DMDs. Conclusion Our study showed beneficial effects of the DMDs used to treat MS on hospitalizations for those aged <55 at the time of exposure. In contrast, for individuals ≥55 years of age exposed to a DMD, the hazard of hospitalization was not significantly lowered. Our study contributes to the broader understanding of the potential benefits and risks of DMD use in the ageing MS population.

Abstract
Objectives To examine the association between the COVID-19 pandemic and opioid use among nursing home residents followed up to March 2021, and possible variation by dementia and frailty status. Design Population-based cohort study with an interrupted time series analysis. Setting and Participants Linked health administrative databases for residents of all nursing homes (n = 630) in Ontario, Canada were examined. Residents were divided into consecutive weekly cohorts (first observation week was March 5 to 11, 2017 and last was March 21 to March 27, 2021). Methods The weekly proportion of residents dispensed an opioid was examined overall and by strata defined by the presence of dementia and frailty. Autoregressive Integrated Moving Average models with step and ramp intervention functions tested for immediate level and slope changes in weekly opioid use after the onset of the pandemic (March 1, 2020) and were fit on prepandemic data for projected trends. Results The average weekly cohort ranged from 76,834 residents (prepandemic) to 69,359 (pandemic period), with a consistent distribution by sex (69% female) and age (54% age 85 + years). There was a statistically significant increased slope change in the weekly proportion of residents dispensed opioids (parameter estimate (β) = 0.035; standard error (SE) = 0.005, P < .001). Although significant for all 4 strata, the increased slope change was more pronounced among nonfrail residents (β = 0.038; SE = 0.008, P < .001) and those without dementia (β = 0.044; SE = 0.008, P < .001). The absolute difference in observed vs predicted opioid use in the last week of the pandemic period ranged from 1.25% (frail residents) to 2.28% (residents without dementia). Conclusions and Implications Among Ontario nursing home residents, there was a statistically significant increase in opioid dispensations following the onset of the pandemic that persisted up to 1 year later. Investigations of the reasons for increased use, potential for long-term use and associated health consequences for residents are warranted.

Abstract
PURPOSE Age or sex concordance (same sex or same age range) may also be associated with medication adherence but was not fully investigated. We aim to quantify the impact of age and sex concordance on optimal adherence to statin medications. PATIENTS AND METHODS A retrospective cohort study was conducted using population-based health administrative data from Saskatchewan, Canada. Participants were individuals newly initiated on statin medications between January 1, 2012, and December 31, 2017. The outcome was optimal adherence (proportion of days covered ≥ 80%) measured at one year after the first statin claim. The independent variables were sex and age concordance (age within five years) between patients and prescribers. The association between adherence outcome and sex/age concordance was analyzed by multivariable logistic regression models using generalized estimating equations controlled by a package of potential confounding factors. RESULTS Among 51,874 new statin users, 20.6% (n = 10,710) were age concordant with prescriber. The vast majority of age concordance occurred in patients younger than 66 years (88.6%, 9,486/10,710). Sex concordance was observed in 62.8% (n = 32,551) of patients and age-sex combined concordance in 13.2% (n = 6,856). Among patients younger than 66 years (n = 36,641/51,874, 70.6%), age concordance did not have a significant impact on optimal adherence [adjusted OR (aOR) = 1.02, 95% CI 0.97 to 1.07]. Weak association between sex concordance (aOR = 1.05, 95% CI 1.00 to 1.11), and age-sex combined concordance (aOR = 1.05, 95% CI 0.99 to 1.12) was observed. CONCLUSION Age and sex concordance were not statistically significant predictors of optimal statin adherence. However, a weak association was detected for sex concordance. Future studies should examine this factor in different health care settings.

Abstract
Objective: We assessed the relationship between the multiple sclerosis (MS) disease-modifying drugs (DMDs) and healthcare use. Methods: Persons with MS (aged ⩾18 years) were identified using linked population-based health administrative data in four Canadian provinces and were followed from the most recent of their first MS/demyelinating event or 1 January 1996 until the earliest of death, emigration, or study end (31 December 2017 or 31 March 2018). Prescription records captured DMD exposure, examined as any DMD, then by generation (first-generation (the injectables) or second-generation (orals/infusions)) and individual DMD. The associations with subsequent all-cause hospitalizations and physician visits were examined using proportional means model and negative binomial regression. Results: Of 35,894 MS cases (72% female), mean follow-up was 12.0 years, with person-years of DMD exposure for any, or any first- or second-generation DMD being 63,290, 54,605 and 8685, respectively. Any DMD or any first-generation DMD exposure (versus non-exposure) was associated with a 24% lower hazard of hospitalization (adjusted hazard ratio, aHR: 0.76; 95% confidence intervals (CIs): 0.71–0.82), rising to 29% for the second-generation DMDs (aHR: 0.71; 95% CI: 0.58–0.88). This ranged from 18% for teriflunomide (aHR: 0.82; 95% CI: 0.67–1.00) to 44% for fingolimod (aHR: 0.56; 95% CI: 0.36–0.87). In contrast, DMD exposure was generally not associated with substantial differences in physician visits. Conclusion: Findings provide real-world evidence of a beneficial relationship between DMD exposure and hospitalizations.

Abstract
Recent research has questioned the notion that Campylobacter jejuni is a harmless resident of the avian gastrointestinal tract (GIT). The following trial examined the effect of dietary supplementation with a mixture of enzymes and Bacillus-based probiotics on growth performance, C. jejuni colonisation, GIT immune responses, faecal shedding and extra-intestinal spread in broilers. Fifty-eight, Ross 308 d-old broilers were randomly assigned to one of four treatments, giving 14 or 15 birds/pen. Birds were given nutritionally complete, complex, phased diets unsupplemented (two treatments) or supplemented (two treatments) with a multi-enzyme containing 2,000 U/kg xylanase, 200 U/kg amylase and 4,000 U/kg protease, and 75,000 cfu/g of a combination of three strains of Bacillus amyloliquefaciens. One control and one supplemented diet group contained birds orally challenged with 105 cfu C. jejuni strain M1 on d 21 of age. Among challenged birds, the mixed-enzymes and probiotic combination numerically reduced faecal C. jejuni shedding (-98% vs challenged control) three days-post-infection (d.p.i.), and at 7 d.p.i. numerically reduced C. jejuni colonisation of the ileal mucosa (-1000-fold vs control) and totally inhibited systemic spread of C. jejuni to the liver, compared to the control (P<0.05). It suppressed early pro-inflammatory chemokine response seen in the ileum, caecum and caecal tonsil tissues (at 3 d.p.i.) in challenged control birds (-18 to -46-fold; P<0.05) and altered expression of pro-inflammatory (IL-1β, IL-6, IL-17A and IL-17F) and regulatory (IL-10 and TGF-β) cytokines. The data demonstrated inhibition of a sustained pro-inflammatory response to C. jejuni infection and improved intestinal barrier integrity in supplemented birds. This highlighted the importance of looking beyond simple measurements of feed conversion and body weight gain when seeking to understand the effects and mode of action of poultry dietary interventions. Achieving a favourable balance between the gut, immune function, microbiome and nutrition should be the goal for achieving good gastrointestinal health and optimal performance.

Abstract
Background Youth are tragically affected by violence. Justice-involved youth are at elevated risk for the effects of violence, as incarceration serves as a risk factor. The objective of this study is to explore the risks and needs of justice-involved youth and identify channels for future hospital-based programming. Methods Four weekly focus groups were conducted by a credible messenger at the Douglas County Youth Center with former participants of Dusk 2 Dawn, a youth violence prevention program delivered at the Douglas County Youth Center. Eight participants were prompted with preset interview questions. All focus groups were recorded and transcribed by a professional transcription service. A thematic analysis was performed by 2 independent coders to identify themes using Dedoose software. Results The 3 most frequently occurring themes involved topics on protection, identified 40 times; family, identified 36 times; and the challenge of overcoming violence, identified 31 times. These themes often overlapped with one another, demonstrating the complexity of youth violence. Conclusion Providing a safe and judgement-free space for the youth to discuss issues of violence was beneficial for 3 reasons: (1) inclusion of youth perspectives allows violence prevention programs to be tailored to specific needs, (2) participants were able to deeply reflect on violence in their own lives and consider steps toward positive change, and (3) open communication encourages trust building and collaborative prevention efforts between the hospital and community.

Abstract
OBJECTIVE To determine whether better medication adherence in multiple sclerosis (MS) might be due to specialised disease-modifying drug (DMD) support programmes by: (1) establishing higher adherence in MS than in other chronic diseases and (2) determining if higher adherence is associated with patient-specific or treatment-specific factors. DESIGN Retrospective cohort study with data from 1 January 1996 to 31 December 2015. SETTING Population-based health administrative data from three Canadian provinces. PARTICIPANTS Individual cohorts were created using validated case definitions for MS, epilepsy, Parkinson's disease (PD) and rheumatoid arthritis (RA). Subjects were included if they received ≥1 dispensation for a disease-related drug between 1 January 1997 and 31 December 2014. MAIN OUTCOME MEASURES Proportion of subjects with optimal adherence (≥80%) measured by the medication possession ratio 1 year after the index date (first dispensation of disease-related drug). RESULTS 126 478 subjects were included in the primary analysis (MS, n=6271; epilepsy, n=55 739; PD, n=21 304; RA, n=43 164). Subjects with epilepsy (adjusted OR, aOR 0.29; 95% CI 0.19 to 0.45), PD (aOR 0.42; 95% CI 0.29 to 0.63) or RA (aOR 0.26; 95% CI 0.19 to 0.35) were less likely to have optimal 1-year adherence compared with subjects with MS. Within the MS cohort, adherence was higher for DMD than for chronic-use non-MS medications, and no consistent patient-related predictors of adherence were observed across all four non-MS medication classes, including having optimal adherence to DMD. CONCLUSIONS Subjects with MS were significantly more likely to have optimal 1-year adherence than subjects with epilepsy, RA and PD, and optimal adherence appears related to treatment-specific factors rather than patient-related factors. This supports the hypothesis that higher adherence to the MS DMDs could be due to the specialised support programmes; these programmes may serve as a model for use in other chronic conditions.

Abstract
BACKGROUND Real-world safety data for the oral multiple sclerosis (MS) disease-modifying therapies (DMTs), dimethyl fumarate (DMF), fingolimod, and teriflunomide are important. We examined laboratory test abnormalities and adverse health conditions in new users. METHODS Linked laboratory and administrative health data were accessed for all persons with MS (PwMS) filling their first oral DMT prescription in two Canadian provinces. PwMS were followed from first prescription fill until discontinuation, death, emigration or study end. Proportions of PwMS, and incidence rates (IR)/100 person-years, were calculated for ≥1 event of elevated alanine aminotransferase (ALT) (>the upper limit of normal [ULN]; all DMTs), liver toxicity (ALT>3xULN; fingolimod); lymphopenia and proteinuria (DMF), and cardiac arrhythmia, hypertension and pneumonia (all DMTs). RESULTS Overall, 1,140 PwMS were followed for up to 2 years. De novo elevated alanine aminotransferase affected 13.2% (DMF), 12.4% (teriflunomide), and 30.0% (fingolimod) of users. Liver toxicity affected 2.8% of fingolimod, lymphopenia 3.1% of DMF, and proteinuria 2.9% of DMF users. The incidences of cardiac arrhythmia, pneumonia and hypertension ranged from <1 to 1.86/100 person-years depending on the DMT. CONCLUSIONS The short-term, real-world incidences of abnormal laboratory results or adverse events were consistent with the pivotal clinical trial findings. Longer-term safety data are still needed.

Abstract
Background: Relatively little is known about the use of disease-modifying drugs (DMDs) for multiple sclerosis (MS) in the population-based universal healthcare setting. This study aimed to describe the characteristics of a population-based cohort with MS and their DMD exposure in four Canadian provinces. Methods: We identified all adults (aged ≥18 years) with MS using linked population-based health administrative data. Individuals were followed from the most recent of their first MS or demyelinating event or 1 January 1996(study entry), to the earliest of death, emigration, or 31 March 2018(study end). Cohort characteristics examined included sex, age, socioeconomic status, and comorbidity burden. Results: Overall, 10,418/35,894 (29%) of MS cases filled a DMD prescription during the 22-year study period. Most were women (n = 7,683/10,418;74%), and 17% (n = 1,745/10,418) had some comorbidity (Charlson Comorbidity Index≥1) at study entry. Nearly 20% (n = 1,745/10,418) were aged ≥50 when filling their first DMD; the mean age was 39.6 years. Conclusions: Almost 1 in 6 people with MS had at least some comorbidity, and nearly 1 in 6 were ≥50 years old at the time of their first DMD. As these individuals are typically excluded from clinical trials, findings illustrate the need to understand the harms and benefits of DMD use in these understudied groups.

Abstract
Background The Saskatchewan Medication Assessment Program (SMAP) compensates community pharmacists for medication reviews on eligible residents with the goal of optimizing patient care. Although medication reviews are meant to reduce risks associated with complex medication regimens, some patients may already be receiving specialized care from interdisciplinary health care teams from the renal programs in Saskatchewan. Objective A qualitative analysis was undertaken to examine the perceptions of health care providers about the SMAP process for patients receiving renal care in Saskatchewan. The goal was to explore potential benefits, facilitators, challenges, and/or barriers of the program in this population. Design Qualitative descriptive study. Setting The semi-structured interviews took place in the province of Saskatchewan. Participants Community pharmacists, renal pharmacist, and nephrologists. Methods All nephrologists, renal pharmacists, and community pharmacies in Saskatoon and Regina were sent an invitation to participate in the study. Semi-structured interviews were completed with participants and were audio-recorded and transcribed verbatim. Coding was performed using NVIVO qualitative software, and meaning units and codes were consolidated into categories and subcategories using qualitative content analysis. Results A total of 9 community pharmacists, 10 renal pharmacists, and 8 nephrologists were interviewed. Community pharmacists had mixed levels of comfort providing SMAP assessments for renal patients, but expressed the desire to provide the best care possible and described patient benefits. Some categories (eg, barriers and improvements) and subcategories (eg, "collaboration/communication", "other challenges," and "suggestions for improvement") were consistent among all participant groups, while others (eg, "renal patients have complex care needs" and "duplication of service") were common among both renal pharmacists and nephrologists. The nephrologists had little knowledge of the program and of the role of the community pharmacist, indicating the need for improved education and communication. Limitations The lack of renal patient perceptions on the SMAP process should be acknowledged and studied in future. A further limitation is the small sample size per subsample group. Conclusion Despite some negative experiences, all of the participants believed the program can be beneficial. However, several recommendations were suggested to improve the SMAP process in renal patients and other complex patient populations.

Abstract
Abstract
Background
T1 mapping by cardiovascular magnetic resonance (CMR) is an accurate tool to assess myocardial extracellular space with wider clinical applications in the aetiological characterization of cardiomyopathies. The aims of the study were to explore a possible role of myocardial T1 mapping in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and in first-degree relatives at risk and to investigate the possible relationship between left ventricular (LV) involvement at CMR and ECG features.
Methods
Thirty patients with ARVC (47% males, mean age 42±22 years) and 59 first-degree relatives who did not fulfil ARVC diagnostic Task Force criteria, underwent full diagnostic work-up including CMR with native and post-contrast T1 mapping.
Results
The CMR was abnormal in 26 (86%) patients with ARVC. The RV was affected in isolation in 13 (43%) patients. Prior to T1 mapping assessment, 2 (7%) patients exhibited isolated LV involvement and 11 (36%) patients showed features of biventricular disease. Left ventricular involvement was manifested as detectable LV late gadolinium enhancement (LGE) in 12 out of 13 cases. According to pre-specified septal T1 mapping thresholds, 11 (37%) patients showed abnormally high native T1 values. Myocardial T1 mapping was higher than normal in 5 (17%) patients who would have been classified as exhibiting a normal LV by conventional imaging. The proportion of patients with abnormal T1 values was similar in patients with or without LGE. Myocardial T1 mapping was higher than normal in 22 (37%) of the 59 first-degree relatives.
Conclusions
Native and/or post contrast myocardial T1 values are raised in almost half of patients with ARVC and in a similar proportion of unaffected first-degree relatives. T1 mapping offers the potential for early detection of LV involvement in patients with ARVC and in first-degree relatives at risk.

Abstract
CAVIAR is a multicentre prospective stepped observational study encompassing 160 patients undergoing vascular intervention. The aim was to identify whether it was feasible to establish a preoperative anaemia pathway and, if so, the efficacy of intravenous iron for treatment of preoperative anaemia. Large barriers prevented implementation of an intravenous iron pathway, with only ten patients receiving intravenous iron and a small increase in haemoglobin level (mean 5·7 (95 per cent c.i. 4·5 to 6·9) g/l). Preoperative anaemia was associated with a longer hospital stay and greater transfusion requirement. Anaemia common and dedicated pathway difficult to instigate.

Abstract
This guideline is an update of a previous version published in 2013. In this new version, we have reflected changes in the way sexual health services are now provided by assuming an integrated Sexual Health/Sexual and Reproductive Healthcare service. There are new recommendations for online testing, female genital mutilation (FGM), chemsex and considerations for transgender (and non-binary) individuals. Previous versions rather assumed a cis-gender clientele and so we have taken a more mechanistic approach to sex and risk without assuming gender identification. We have updated our gender terminology in line with the British Association for Sexual Health and HIV 'sexual health standards for trans, including non-binary, people' although have retained the terminology of 'men' and 'women' in a few cases where it related to other guidelines, e.g. human papillomavirus vaccination and FGM.

Abstract
BACKGROUND There is increasing evidence of prodromal multiple sclerosis (MS). OBJECTIVE The aim of this study was to determine whether fatigue, sleep disorders, anaemia or pain form part of the MS prodrome. METHODS This population-based matched cohort study used linked administrative and clinical databases in British Columbia, Canada. The odds of fatigue, sleep disorders, anaemia and pain in the 5 years preceding the MS cases' first demyelinating claim or MS symptom onset were compared with general population controls. The frequencies of physician visits for these conditions were also compared. Modifying effects of age and sex were evaluated. RESULTS MS cases/controls were assessed before the first demyelinating event (6863/31,865) or MS symptom onset (966/4534). Fatigue (adj.OR: 3.37; 95% CI: 2.76-4.10), sleep disorders (adj.OR: 2.61; 95% CI: 2.34-2.91), anaemia (adj.OR: 1.53; 95% CI: 1.32-1.78) and pain (adj.OR: 2.15; 95% CI: 2.03-2.27) during the 5 years preceding the first demyelinating event were more frequent among cases, and physician visits increased for cases relative to controls. The association between MS and anaemia was greater for men; that between MS and pain increased with age. Pre-MS symptom onset, sleep disorders (adj.OR: 1.72; 95% CI: 1.12-2.56) and pain (adj.OR: 1.53; 95% CI: 1.32-1.76) were more prevalent among cases. CONCLUSION Fatigue, sleep disorders, anaemia and pain were elevated before the recognition of MS. The relative anaemia burden was higher in men and pain more evident among older adults.
