RESUMEN
Importance: We designed an online educational program for primary care health care providers, the Hypertension Canada Professional Certification Program (HC-PCP), based upon its 2020 guidelines. Objective: The objective was to determine the effect of the HC-PCP, taken by pharmacists, on systolic blood pressure (BP) in patients with poorly controlled hypertension. Design: Stepped wedge cluster randomized trial (unit of randomization was the pharmacy). Participants: Patients with poorly controlled hypertension (BP >140/90 mmHg or >130/80 mmHg [diabetes]) in community pharmacies in Alberta, Canada, were recruited by their pharmacist. Intervention: Pharmacists completed the HC-PCP program, then provided care to their patients with poorly controlled hypertension according to what they learned in the course. Control: Pharmacists were given a copy of the Hypertension Canada guidelines and provided their usual care to their patients prior to undertaking the HC-PCP later. Main outcome and measure: The primary outcome was a difference in change in systolic BP at 3 months between groups, while the secondary outcome was patient satisfaction with using the Consultation Satisfaction Questionnaire. Results: We enrolled 890 patients from 59 pharmacies (including 104 pharmacists). Using a linear mixed-effect model with BP reduction as the dependent variable and independent variables of treatment allocation, baseline BP, site effect and patient effect, the intervention was associated with a 4.76 mmHg (95% confidence interval, 2.02-7.50, p < 0.0001) systolic BP reduction at 3 months. Patient satisfaction with using the Consultation Satisfaction Questionnaire was high at 75.9 (/90). Conclusion and relevance: Most educational programs are not evaluated at the patient care level. The HC-PCP taken by pharmacists resulted in a 4.76 mmHg systolic BP reduction in their patients over 3 months. This would have major implications for public health, reducing heart disease, stroke and kidney failure.
RESUMEN
Background: Measurement of home blood pressure is an important tool for the management of hypertension. However, the validity of home devices is of concern. The Recommended Blood Pressure Devices Program of Hypertension Canada reviews and recommends blood pressure devices using international validation standards. We sought to determine the proportion of Hypertension Canada-recommended devices available for purchase in pharmacies and online. Methods: We visited 16 community pharmacies in the Edmonton area to record the blood pressure devices they sold. We also reviewed the 50 most popular devices from online retailers (Amazon, Walmart, Best Buy, and Canadian Tire). All devices were referenced against the Recommended Blood Pressure Device Program of Hypertension Canada (www.hypertension.ca/bpdevices) to determine if the models were recommended. Results: We reviewed 170 devices. Of those sold in pharmacies, 61 of 68 (89.7%) were Hypertension Canada-recommended devices, whereas online retailers had only 46 of 102 (45.1%) recommended devices; P < 0.001. Conclusions: Most blood pressure devices sold in pharmacies are Hypertension Canada recommended, in contrast to less than one-half from online retailers. The lack of validation of many home blood pressure devices could have important clinical implications, leading to over- or undertreatment of hypertension. Clinicians should advise patients on the importance of home blood pressure device validation and direct them to resources such as Hypertension Canada (https://hypertension.ca/public/recommended-devices) for guidance.
Contexte: La mesure de la pression artérielle au domicile est un outil important dans la prise en charge de l'hypertension. Or, il semble que les appareils utilisés à la maison à cette fin ne soient pas toujours des dispositifs validés. Dans le cadre de son Programme de recommandation d'appareils de mesure de la pression artérielle, Hypertension Canada analyse et recommande des tensiomètres selon des normes de validation internationales. Nous avons donc cherché à déterminer la proportion des tensiomètres recommandés par Hypertension Canada qu'il est possible d'acheter dans les pharmacies et en ligne. Méthodologie: Nous avons rendu visite à 16 pharmacies communautaires dans la région d'Edmonton pour recenser les tensiomètres qui y étaient vendus. Nous avons également analysé les 50 tensiomètres les plus vendus par des détaillants en ligne (Amazon, Walmart, Best Buy et Canadian Tire). Nous avons vérifié si chacun des modèles faisait partie de la liste des appareils recommandés par Hypertension Canada (www.hypertension.ca/bpdevices). Résultats: Nous avons passé en revue 170 appareils. Dans les pharmacies, 61 appareils sur 68 (89,7 %) étaient recommandés par Hypertension Canada, alors qu'en ligne, cette proportion n'était que de 46 sur 102 (45,1 %); p < 0,001. Conclusions: La plupart des tensiomètres vendus dans les pharmacies sont recommandés par Hypertension Canada, contrairement à moins de la moitié de ceux qui sont vendus en ligne. L'absence de validation pour de nombreux tensiomètres pourrait avoir d'importantes conséquences cliniques, menant à un traitement excessif ou insuffisant de l'hypertension. Les cliniciens doivent informer les patients de l'importance d'utiliser un tensiomètre validé à la maison et les orienter vers des ressources comme Hypertension Canada (https://hypertension.ca/public/recommended-devices) pour guider leur choix.
RESUMEN
BACKGROUND: Heart failure is a clinical condition with high mortality and morbidity that occurs when the heart is unable to pump enough blood to meet the metabolic demands of the body. The pharmacological management of heart failure has been revolutionized over the past decade with novel treatments. OBJECTIVE: The aim of the review is to highlight the recent pharmacological advances in the management of heart failure. RESULTS: Sodium-glucose cotransporter-2 inhibitor (SGLT2i), iron carboxymaltose, finerenone, omecamtiv mecarbil, and vericiguat have been shown to reduce hospitalization for heart failure. However, only SGLT2i, vericiguat, and omecamtiv mecarbil have been shown to reduce cardiovascular death. Finerenone has been shown to reduce cardiovascular events and renal adverse outcomes in patients with diabetes and kidney disease. Currently, only SGLT2i has been studied in patients beyond the heart failure with reduced ejection fraction population. CONCLUSION: The current quadruple therapy in the treatment of heart failure has demonstrated a reduction in the hospitalization of patients and a decrease in mortality associated with the condition. Individualized heart failure therapy research have shown some benefit in select heart failure patients. Further research on novel therapies will help improve heart failure patient outcomes.

Purpose: This cross-sectional study aimed to investigate the sectoral variance of optical coherence tomography (OCT) and OCT angiography (OCTA) glaucoma diagnostic parameters across eyes with varying degrees of refractive error. Methods: Healthy participants, including individuals with axial ametropia, enrolled in the Hong Kong FAMILY cohort were imaged using the Avanti/AngioVue OCT/OCTA system. The OCT and OCTA parameters obtained include peripapillary nerve fiber layer thickness (NFLT), peripapillary nerve fiber layer plexus capillary density (NFLP-CD), and macular ganglion cell complex thickness (GCCT). Sectoral measurements of NFLT, NFLP-CD, and GCCT were based on sectors and hemispheres. Results: A total of 1339 eyes from 791 participants were stratified based on spherical equivalent refraction: high myopia (<-6 D), low myopia (-6 D to -1 D), emmetropia (-1 D to 1 D), and hyperopia (>1 D). Multivariable broken stick regression models, accounting for age, sex, and signal strength, showed that all NFLT sectors except temporally, the inferior GCCT hemisphere, and half of the NFLP-CD sectors were more affected by ametropia-related covariates than the corresponding global parameters. As expected, the false-positive rates in those sectors were elevated. Finally, sector-specific axial length (AL) and spherical equivalent (SE) adjustments helped reduce the elevated false-positive rates. Conclusions: The effect of optical magnification is even more prominent among sectors than the global parameters. AL- and SE-based adjustments should be individualized to each sector to mitigate this magnification bias effectively. Translational Relevance: Identifying sectoral differences among diagnostic parameters and adopting these sector-based adjustments into commercial OCT systems will hopefully reduce false-positive rates related to refractive error.

BACKGROUND: Community pharmacists were the face of the health response to the unprecedented COVID-19 pandemic. Their pivotal role during the pandemic has been widely recognized, as they adapted to continue to provide a higher level of care to their patients. OBJECTIVE: The objective of this study was to gain a deeper understanding of frontline pharmacists' lived experiences of the COVID-19 pandemic and its impact on their roles. METHODS: Photovoice, a visual research method that uses participant-generated photographs to articulate their experiences, was used with semi-structured interviews to explore pharmacists' lived experiences. Frontline community pharmacists who provided direct patient care during the COVID-19 pandemic in Alberta, Canada were recruited. Participants were asked to provide 3-5 photos that reflected on how they see themselves as a pharmacist and/or represents what they do as a pharmacist. Data analysis incorporated content, thematic and visual analysis and was facilitated using NVivo software. A published conceptual framework model was used as the foundation of the analysis with care taken to include new concepts. Ethics approval was obtained from the University of Alberta health research ethics board. RESULTS: Interviews were conducted with 21 participants and they 71 photos. This study advanced the conceptual framework model presented in a scoping review, of what was made visible (pharmacists' information, public health, and medication management roles) and what was invisible but made visible by the pandemic (pharmacists' leadership roles). It was revealed through the reflective nature of this study the important leadership role pharmacists have in their communities. CONCLUSIONS: This study highlighted the work of community pharmacists responding to the COVID-19 pandemic through their information, public health, medication management, and leadership roles. Their experiences also made visible the cost their work had on them as they did more to adapt and continually respond as the pandemic evolved. Pharmacists recognized their role as leaders in their practice and communities.

Heart failure (HF) is a complex clinical syndrome involving structural and/or functional abnormalities of the heart. Heart failure is often classified based on left ventricular ejection fraction, which serves as a predictor of mortality. The majority of the data supporting disease-modifying pharmacological therapies are from patients with reduced ejection fraction (less than 40%). However, with the recent results from the sodium glucose cotransporter-2 inhibitor trials, there is renewed interest in identifying potential beneficial pharmacological therapies. This review focuses on and includes pharmacological HF therapies across the spectrum of ejection fraction, providing an overview of the novel trials. We also examined the effects of the treatments on mortality, hospitalization, functional status, and biomarker levels to further investigate the interplay between ejection fraction and HF.
RESUMEN
Sodium glucose cotransporter 2 inhibitor (SGLT2i) is a class of drugs that were originally intended for decreasing blood glucose in diabetes. However, recent trials have shown that there are other beneficial effects. Major clinical trials involving SGLT2i medications from 2015 to 2022 were reviewed using PUBMED search. Recent major SGLT2i landmark trials have demonstrated benefits for cardiovascular disease (reduce major adverse cardiovascular events (heart attack, stroke, cardiovascular death), hospitalization for heart failure, all-cause death), and renal disease (delay the onset of dialysis) regardless of diabetic status. The consistent cardiorenal benefits observed in major landmark trials have resulted in the rapid adoption of SGLT2i therapy not only in diabetes guidelines but also cardiovascular and renal guidelines.

BACKGROUND/AIMS: To assess the normative values and parameters of optical coherence tomography angiography (OCTA) influencing the best corrected visual acuity (BCVA) in adults aged 50 and above. METHODS: This was a prospective cross-sectional study from an eye screening programme in Hong Kong for 4188 citizens aged 50 and above. Images were analysed using a validated quantification software calculating vessel density and capillary perfusion density (CPD), along with other OCTA parameters, such as the foveal avascular zone area (FAZ) and circularity. OCTA data was collected from May 2019 to December 2020, including a total of 4188 healthy eyes from 4188 subjects. RESULTS: Mean superficial vessel density (MSVD) was 14.48 ± 3.60 mm- 1, while the mean capillary perfusion density (MCPD) was 0.41 ± 0.06. Multivariate analysis revealed ageing (ß = 0.321, p < 0.001), being male (ß=-0.089, p < 0.001), having a high body mass index (BMI) (ß = 0.039, p = 0.006), high FAZ area and low FAZ circularity (ß = 0.039 and - 0.034, p = 0.01 and 0.024 respectively), low MSVD in the outer ring (ß=-0.513, p < 0.001), specifically in the nasal and temporal outer quadrants (ß = -0.226 and - 0.259, p < 0.001 for both), and low MCPD in the outer superior quadrant (ß= -0.123, p = 0.016) being independently associated with BCVA. CONCLUSION: High FAZ area and low FAZ circularity, low MSVD in the outer ring, specifically the nasal and temporal outer quadrants, and low MCPD in the outer superior quadrant can be used as biomarkers in predicting a low visual acuity in adults aged 50 and above.

Purpose: The purpose of this study was to correct refractive error-associated bias in optical coherence tomography (OCT) and OCT angiography (OCTA) glaucoma diagnostic parameters. Methods: OCT and OCTA imaging were obtained from participants in the Hong Kong FAMILY cohort. The Avanti/AngioVue OCT/OCTA system was used to measure the peripapillary nerve fiber layer thickness (NFLT), peripapillary nerve fiber layer plexus capillary density (NFLP-CD), macular ganglion cell complex thickness (GCCT), and macular superficial vascular complex vascular density (SVC-VD). Healthy eyes, including ones with axial ametropia, were enrolled for analysis. Results: A total of 1346 eyes from 792 participants were divided into 4 subgroups: high myopia (<-6D), low myopia (-6D to -1D), emmetropia (-1D to 1D), and hyperopia (>1D). After accounting for age, sex, and signal strength, multivariable regression showed strong dependence in most models for NFLT, GCCT, and NFLP-CD on axial eye length (AL), spherical equivalent (SE) refraction, and apparent optic disc diameter (DD). Optical analysis indicated that AL-related transverse optical magnification variations predominated over anatomic variations and were responsible for these trends. Compared to the emmetropic group, the false positive rates were significantly (Chi-square test P < 0.003) elevated in both myopia groups for NFLT, NFLP-CD, and GCCT. Regression-based adjustment of these diagnostic parameters with AL or SE significantly (McNemar test P < 0.03) reduced the elevated false positive rates. Conclusions: Myopic eyes are biased to have lower NFLT, GCCT, and NFLP-CD measurements. AL- and SE-based adjustments were effective in mitigating this bias. Translational Relevance: Adoption of these adjustments into commercial OCT systems may reduce false positive rates related to refractive error.

BACKGROUND: Diabetes is a major risk factor for developing cardiovascular disease. Patients with both diabetes and cardiovascular disease have even higher mortality. The convergence of cardiology and diabetology therapy is an important step in treating patients and advancing research. RESULTS: Major landmark trials and meta-analyses involving Sodium Glucose Cotransporter 2 inhibitors have shown dramatic clinical cardiorenal benefits in patients both with and without type 2 diabetes. In type 2 diabetes patients, Glucagon-like peptide-1 receptor agonists have been shown to improve major cardiac outcomes. CONCLUSION: This hot topic of research and clinical use of glucose lowering drugs intersects the fields of cardiovascular, renal, and diabetic medicine. The numerous cardiorenal benefits have led to the rapid adoption in clinical guidelines of these glucose lowering drugs in patients with Type 2 diabetes, cardiovascular disease, or renal disease.

Septic arthritis of the smaller acromioclavicular joint is uncommon, with only a few reports and case series available in the literature. The aim of this outcomes analysis was to determine the prevalence of shoulder girdle septic arthritis within the authors' institution, with a particular focus on describing the authors' experience with acromioclavicular joint septic arthritis. A retrospective outcomes analysis was conducted of patients admitted to a single tertiary referral center from 2008 to 2018 with acromioclavicular joint septic arthritis. Demographic and clinical data were recorded for each patient; the modified Frailty Index score was calculated for each patient. Nine patients were identified as having acromioclavicular joint septic arthritis, making up 12% of shoulder girdle septic arthritis. Diabetes mellitus was the most prevalent comorbidity, present in 4 (44.4%) patients. Staphylococcus aureus was responsible in 55.6% and Streptococcus species in 44.4%. Seven patients were treated surgically. Mean (SD) length of antibiotic therapy was 6.2 (2.7) weeks. Mean (SD) length of stay was 6 (2.83) days (range, 4-8 days) for patients who received antibiotic therapy only and 12.7 (7.52) days for those who proceeded for operative management. Mean modified Frailty Index score was 1.1. Septic arthritis of the acromioclavicular joint is an uncommon infection that occurs both in patients with impaired immunity and in those with intact immune systems. Tailored antimicrobial therapy in conjunction with surgical intervention, when indicated, appears to result in successful suppression or eradication of infection in the majority of cases.

OBJECTIVES: The objective was to bridge the relative educational gap for newly matched emergency medicine preinterns between Match Day and the start of internship by implementing an Accreditation Council for Graduate Medical Education Milestone (ACGME)-based virtual case curriculum over the social media platform Slack. METHODS: We designed a Milestone-based curriculum of 10 emergency department clinical cases and used Slack to implement it. An instructor was appointed for each participating institution to lead the discussion and encourage collaboration among preinterns. Pre- and postcurriculum surveys utilized 20 statements adapted from the eight applicable Milestones to measure the evolution of preintern self-reported perceived preparedness (PP) as well as actual clinical knowledge (CK) performance on a case-based examination. RESULTS: A total of 11 institutions collaborated and 151 preinterns were contacted, 127 of whom participated. After participating in the Slack intern curriculum (SIC), preinterns reported significant improvements in PP regarding multiple Milestone topics. They also showed improved CK regarding the airway management Milestone based on examination performance. CONCLUSIONS: Implementation of our SIC may ease the difficult transition between medical school and internship for emergency medicine preinterns. Residency leadership and medical school faculty will benefit from knowledge of preintern PP, specifically of their perceived strengths and weaknesses, because this information can guide curricular focus at the end of medical school and beginning of internship. Limitations of this study include variable participation and a high attrition rate. Further studies will address the utility of such a virtual curriculum for preinterns and for rotating medical students who have been displaced from clinical rotations during the novel coronavirus pandemic.
RESUMEN
INTRODUCTION: Various sacropelvic parameters such as the pelvic Incidence (PI) are used to predict ideal lumbar lordosis and aid surgical planning. The objective of this study was to establish the relationship between the location of the aortic bifurcation from the sacral promontory and sacropelvic measures including the PI. MATERIALS AND METHODS: One hundred sixty five computed tomography (CT) scans obtained for major trauma including the entire spine were identified. Sacropelvic parameters including PI, sacral anatomic orientation, pelvic thickness (PTH), and sacral table angle were measured. Aortic bifurcation was identified on sagittal and coronal imaging and the distance from the sacral promontory (bifurcation-promontory distance [BPD]) measured (mm). RESULTS: Mean age of the cohort was 44.3 years (SD 18.5; range 16-88 years); 61.8% male. The mean PI was 49.2° (SD 10.2°; range 30°-80°). The mean BPD was 66.4 mm (SD 13.1 mm; range 38.3-100 mm). In the majority, the bifurcation was at the level of the L4 vertebral body (72.7%). Only age (r = -.389; p < .0001) and PTH (r = .172; p = .027) correlated with the BPD to a significant degree. PI did not correlate with BPD (r = .061; p = .435). Linear regression analysis provided the following predictive equation: BPD = 34.3 mm + 0.30 × PTH. CONCLUSION: This study demonstrates a lack of any meaningful correlation between sagittal pelvic parameters and the distance of the aortic bifurcation from the sacral promontory. Surgical planning for fusion surgery in the lumbar spine should include assessment of spinopelvic parameters and if anterior access to the lumbar disc(s) necessary, vascular anatomy should be carefully assessed independent of these measures.

OBJECTIVE: To compare four screening strategies for diabetic macular edema (DME). RESEARCH DESIGN AND METHODS: Patients attending diabetic retinopathy screening were recruited and received macular optical coherence tomography (OCT), in addition to visual acuity (VA) and fundus photography (FP) assessments, as part of the standard protocol. Two retina specialists provided the reference grading by independently assessing each subject's screened data for DME. The current standard protocol (strategy A) was compared for sensitivity, specificity, quality-adjusted life-year (QALY) gained, and incremental cost-effectiveness ratio (ICER) with three alternative candidate protocols using a simulation model with the same subjects. In strategy B, macular hemorrhage or microaneurysm on FP were removed as surrogate markers for possible DME. Strategy C used best-corrected instead of habitual/pinhole VA and added central subfield thickness (CST) >290 µm on OCT in suspected cases as a confirmation marker for possible DME. Strategy D used CST >290 µm OCT in all subjects as a surrogate marker for suspected DME. RESULTS: We recruited 2,277 subjects (mean age 62.80 ± 11.75 years, 43.7% male). The sensitivities and specificities were 40.95% and 86.60%, 22.86% and 95.63%, 32.38% and 100%, and 74.47% and 98.34% for strategies A, B, C, and D, respectively. The costs (in U.S. dollars) of each QALY gained for strategies A, B, C, and D were $7,447.50, $8,428.70, $5,992.30, and $4,113.50, respectively. CONCLUSIONS: The high false-positive rate of the current protocol generates unnecessary referrals, which are inconvenient for patients and costly for society. Incorporating universal OCT for screening DME can reduce false-positive results by eightfold, while improving sensitivity and long-term cost-effectiveness.

Despite advances in ophthalmic diagnostics, the direct ophthalmoscope remains a key clinical skill taught to medical students and is the tool of choice for retina examination among non-ophthalmic physicians. However, in recent years viable alternatives have become available. The coronavirus disease 2019 (COVID-19) pandemic has forced a major re-thinking in medical education worldwide. In this commentary, we examined the current merits and limitations of the direct ophthalmoscope in both the clinical sense and in the context of infection control. Furthermore, we compared the direct ophthalmoscope with alternatives, including commercially available portable non-mydriatic fundus cameras, that would allow a change in focus during ophthalmic teaching. We concluded that the latter will better prepare our medical students for the age of telemedicine and deep-learning systems. While the COVID-19 pandemic will not be the sole reason for the 'death' of the direct ophthalmoscope, the global situation will inevitably serve to expedite long overdue changes in our teaching of ophthalmic skills to non-ophthalmic physicians.
