Ultrasonography of Superficial Soft-Tissue Masses: Society of Radiologists in Ultrasound Consensus Conference Statement.

The Society of Radiologists in Ultrasound convened a panel of specialists from radiology, orthopedic surgery, and pathology to arrive at a consensus regarding the management of superficial soft-tissue masses imaged with US. The recommendations in this statement are based on analysis of current literature and common practice strategies. This statement reviews and illustrates the US features of common superficial soft-tissue lesions that may manifest as a soft-tissue mass and suggests guidelines for subsequent management.

Recommended Musculoskeletal and Sports Ultrasound Terminology: A Delphi-Based Consensus Statement.

OBJECTIVES: The current lack of agreement regarding standardized terminology in musculoskeletal and sports ultrasound presents challenges in education, clinical practice, and research. This consensus was developed to provide a reference to improve clarity and consistency in communication. METHODS: A multidisciplinary expert panel was convened consisting of 18 members representing multiple specialty societies identified as key stakeholders in musculoskeletal and sports ultrasound. A Delphi process was used to reach consensus which was defined as group level agreement >80%. RESULTS: Content was organized into seven general topics including: 1) General Definitions, 2) Equipment and Transducer Manipulation, 3) Anatomic and Descriptive Terminology, 4) Pathology, 5) Procedural Terminology, 6) Image Labeling, and 7) Documentation. Terms and definitions which reached consensus agreement are presented herein. CONCLUSIONS: The historic use of multiple similar terms in the absence of precise definitions has led to confusion when conveying information between colleagues, patients, and third-party payers. This multidisciplinary expert consensus addresses multiple areas of variability in diagnostic ultrasound imaging and ultrasound-guided procedures related to musculoskeletal and sports medicine.

Large pertussis outbreak in rural Canada: Lessons learned from Haida Gwaii.

OBJECTIVE: To present characteristics of and response to a large outbreak of pertussis on Haida Gwaii, BC, in 2014. DESIGN: Quantitative descriptive review. SETTING: Haida Gwaii, a remote island archipelago located 100 km off of British Columbia's west coast. PARTICIPANTS: All patients presenting with symptoms evaluated for pertussis on Haida Gwaii between February and August 2014. MAIN OUTCOME MEASURES: The primary outcome measures included the demographic characteristics, time course, and morbidity of the outbreak. The secondary outcome measures included the laboratory result reports, the effects on clinician workload, and the treatment and prophylaxis practices. Statistical analysis for significance of pertussis severity and immunization status was performed with a maximum-likelihood framework. RESULTS: Between February and August 2014, out of 873 clinical encounters, 579 patients were seen for pertussis-related care. Of these, 260 patients were reported to public health for case identification, contact tracing, and follow-up. There were 123 cases of probable and confirmed pertussis, a case rate of 2795 cases per 100 000 population. Of these 123 cases, 91 had a cough of more than 2 weeks' duration. A subset of patients presented with mild symptoms, atypical of pertussis. Nasopharyngeal swabs were collected on 221 occasions, 378 antibiotic prescriptions were written, and 248 prophylactic immunizations were given. The odds ratio that previous immunization protected against the development of classic pertussis was 0.23; however, statistical significance was not reached (P = .112). CONCLUSION: Pertussis is resurging. Physicians need to remain vigilant for its characteristic symptoms. Clear and standardized criteria for the declaration of an outbreak should be developed. To contain an outbreak, it is crucial to deploy resources commensurate with disease activity while coordinating public health and primary care. More research into why large outbreaks continue to occur, why endemic rates continue to rise, and how these can be most effectively prevented is essential.

Systematic community- and hospital-based surveillance for enterovirus-D68 in three Canadian provinces, August to December 2014.

Respiratory specimens collected from outpatients with influenza-like illness in three Canadian provinces (British Columbia (BC), Alberta and Quebec) participating in a community-based sentinel surveillance network were prospectively screened for enterovirus-D68 (EV-D68) from 1 August to 31 December 2014 and compared to specimens collected from 1 October 2013 to 31 July 2014. Eighteen (1%) of 1,894 specimens were EV-D68-positive: 1/348 (0.3%) collected from October to December 2013 and 11/460 (2.4%) from October to December 2014, an eight-fold increase in detection rates (p=0.01), consistent with epidemic circulation in autumn 2014. The remaining EV-D68 detections were in September 2014 (6/37). Enhanced passive surveillance was also conducted on all inpatient and outpatient EV-D68 cases (n=211) detected at the BC provincial reference laboratory from 28 August to 31 December 2014. Incidence of hospitalisations was 3/100,000 overall and 21, 17, 4 and 1/100,000 among those<5, 5-9, 10-19 and ≥20-years-old with male-to-female ratios>1 among paediatric but not adult cases. Three cases in BC with comorbidity or co-infection died and five exhibited neurological features persisting >9 months. Active surveillance in outpatient and inpatient settings is needed from more areas and additional seasons to better understand EV-D68 epidemiology and potential at-risk groups for severe or unusual manifestations.

Social prescribing in Canada: health promotion in action, 50 years after the Lalonde report. / La prescription sociale au Canada : la promotion de la santé en action, 50 ans après le rapport Lalonde.

The Lalonde report, published in 1974 by the Canadian Minister of National Health and Welfare, broke ground for public health in Canada by acknowledging that the determinants of health are much broader than health care services. Fifty years later, this special issue of Health Promotion and Chronic Disease Prevention in Canada charts a clear path towards addressing upstream determinants of health through an emerging intervention called "social prescribing." Social prescribing connects patients with community resources tailored to their individual priorities, fostering a paradigm shift from a deficitbased to a strengths-based approach in health promotion. Part 1 of this issue covers the rapid growth and diverse applications of social prescribing across Canada, with targeted initiatives for various populations and interventions ranging from nature and arts to physical activity and social connectivity. Contributions from a wide range of partners, including researchers, health professionals and community members, explore the adaptability of social prescribing for different groups, underscore the role of community and lived experiences in research, and call for more studies on social prescribing's effectiveness and outcomes. Highlighted case studies demonstrate tangible benefits in health equity and access to social services. This issue not only reflects the current scope and impact of social prescribing in Canada but also sets the stage for its future development and integration into broader health practices.

Social prescribing connects patients with nonmedical resources, shifting the focus from deficits to a strengths-based approach in health. Growing initiatives target diverse populations including caregivers, youth, racialized peoples and Indigenous communities. Case studies demonstrate social prescribing's benefits in health equity and expanding access to essential services.

La prescription sociale oriente les patients vers des ressources non médicales, selon une approche de la santé qui se concentre sur les forces plutôt que sur les déficits. Les initiatives se multiplient à l'intention de populations particulières comme les aidants naturels, les jeunes, les personnes racisées ou les collectivités autochtones. Des études de cas montrent que la prescription sociale favorise l'équité en santé et un accès élargi aux services essentiels.

Therapeutic Potential of Psilocybin for Treating Psychological Distress among Survivors of Adverse Childhood Experiences: Evidence on Acceptability and Potential Efficacy of Psilocybin Use.

Survivors of adverse childhood experience are at elevated risk for psychological distress. In recent years, renewed interest in psychedelic medicine has highlighted the therapeutic potential of psilocybin for those who have experienced childhood adversity. However, recreational psilocybin use remains illegal and access to approved therapies is difficult. Such use provides an opportunity to explore the therapeutic potential of psilocybin for psychological distress among people with adverse childhood experiences. Therefore, we conducted an online survey to assess interest in, acceptability of, and experiences with psilocybin. We further explored whether the association between Adverse Childhood Experiences Questionnaire (ACEQ) scores and psychological distress was lower among those who had used psilocybin in the past three months. Results showed high levels of interest in and acceptability of psilocybin that did not differ across ACEQ scores. Results also showed that the effect of adverse childhood experiences on psychological distress was lower for people who had recently used psilocybin (p = .019). Taken together, these findings suggest that psilocybin therapy may be potentially acceptable and may feasibly help in supporting survivors of adverse childhood experiences with particularly strong benefits to those with more severe childhood adversity.

Invasive group A streptococcal (iGAS) surveillance in Island Health, British Columbia, 2022.

Background: Invasive group A streptococcal disease (iGAS) is caused by Streptococcus pyogenes group A bacteria. In 2022, multiple disease alerts for iGAS in the Island Health region, in the context of increased infections in the paediatric population in Europe and the United States, prompted further investigation into local trends. This surveillance study summarizes epidemiological trends of iGAS in the region covered by Island Health, a regional health authority in British Columbia, in 2022. Methods: In British Columbia, iGAS is a reportable disease; all confirmed cases are reported to the regional authority and the provincial health authority (BC Centre for Disease Control). Island Health's iGAS surveillance system is passive and collects information on cases that are identified through laboratory testing. Surveillance data were summarized for 2022 and compared with historical data from 2017-2021. Results: In 2022, the incidence rate was 11.4 cases per 100,000 population (n=101), the highest observed rate in the last six years. The median age of cases was 53 years, with a range of 0-96 years, and 64% of cases were male. The highest risk of infection was reported in men 40-59 years of age, with an incidence rate of 21.3 cases per 100,000 population. The most common emm types were emm92 (n=14), emm49 (n=13), and emm83 (n=12). Overall, 85% (n=86) of cases were hospitalized, 21% (n=21) were admitted to the intensive care unit, and 6% (n=6) died. Conclusion: This study highlights that the incidence of iGAS in the Island Health region continued to increase throughout the coronavirus disease 2019 (COVID-19) pandemic, reaching its highest annual rate in 2022. In contrast to reports from Europe and the United States, there was no notable increase in infections in the paediatric population. Given the sustained increase in iGAS activity, continued monitoring and description of the epidemiology of these cases on a regular basis is imperative.

The CIRAS study: a case control study to define the clinical, immunologic, and radiographic features of aromatase inhibitor-induced musculoskeletal symptoms.

Aromatase inhibitors (AIs) are widely prescribed for post-menopausal hormone receptor-positive breast cancer; however, musculoskeletal symptoms limit their tolerability. The purpose of this study was to determine whether joint pain in women receiving AIs is associated with inflammatory arthritis as measured by the disease activity score-28 (DAS-28), and to evaluate association with tenosynovitis on ultrasound. A total of 48 postmenopausal women with stage I-III breast cancer and hand pain were recruited from the Lombardi Comprehensive Cancer Center. Those receiving AIs were cases (n = 25), and those not receiving AIs were controls (n = 23). During a single study visit, subjects underwent blinded rheumatologic evaluation, DAS-28, health assessment questionnaires, autoantibodies, inflammatory markers, hand X-ray, and hand Duplex ultrasound. There were no significant differences between cases and controls in DAS-28, or inflammatory markers. A positive ANA (titer > 1:160) was found in ten patients, four of whom met criteria for autoimmune disease (two with rheumatoid arthritis and two with Sjogren's syndrome, equally distributed among cases and controls). This highlights the importance of considering underlying autoimmune disease in subjects with musculoskeletal complaints. Morning stiffness was more prolonged in women receiving AIs, but this did not reach statistical significance (P = 0.07). Ultrasound evidence of flexor tenosynovitis was common in both groups. Although tenosynovitis was not correlated with AI use (P = 0.26), there was a trend toward an association between tenosynovitis and morning stiffness (P = 0.089). While aromatase inhibitor-induced musculoskeletal symptoms (AIMSS) were more common in subjects receiving AIs, they were not unique to AI users. There was no association between presence of AIMSS features and other chemotherapy or medication exposures. Although the majority of subjects had been using AIs for more than 6 months, this study did not find evidence for inflammatory arthritis in women with hand pain receiving AIs. Further studies are needed to develop a case definition of AIMSS, and to confirm whether these symptoms are attributable to AI use.

US of the ovary and adnexa: to worry or not to worry?

Ultrasonography (US) is typically the first study to be requested in patients with clinical findings that may suggest pelvic disease. The evaluation of adnexal masses is a common component of the sonologist's workload, and US has been shown to be accurate for both detecting and characterizing these masses, most of which are either insignificant or benign and therefore require little or no follow-up. Recognition of the most common benign ovarian and extraovarian adnexal masses should help avoid additional or unnecessary imaging. US features that suggest malignancy include thick septations, vascularized solid components, or areas of focal wall thickening, and identifying these features will result in timely management. Indeterminate-appearing masses demonstrate atypical features and cannot easily be classified as definitely either benign or malignant. Proper reporting and management recommendations serve to alleviate both patient anxiety and physician misinterpretation. Knowledge of these recommendations and of the characteristic US features of benign, malignant, and indeterminate adnexal masses can serve as important guidelines for patient management.

Escherichia coli O103 outbreak associated with minced celery among hospitalized individuals in Victoria, British Columbia, 2021.

Background: In April 2021, a Shiga toxin-producing Escherichia coli (E. coli) (STEC) O103 outbreak was identified among patients at two hospitals in Victoria, British Columbia (BC). The objective of this study is to describe this outbreak investigation and identify issues of food safety for high-risk products prepared for vulnerable populations. Methods: Confirmed cases of E. coli O103 were reported to the Island Health communicable disease unit. The provincial public health laboratory conducted whole genome sequencing on confirmed case isolates, as per routine practice for STEC in BC. Exposure information was obtained through case interviews and review of hospital menus. Federal and local public health authorities conducted an inspection of the processing plant for the suspect source. Results: Six confirmed cases of E. coli O103 were identified, all related by whole genome sequencing. The majority of cases were female (67%) and the median age was 61 years (range 24-87 years). All confirmed cases were inpatients or outpatients at two hospitals and were exposed to raw minced celery within prepared sandwiches provided by hospital food services. A local processor supplied the minced celery exclusively to the two hospitals. Testing of product at the processor was infrequent, and chlorine rinse occurred before mincing. The spread of residual E. coli contamination through the mincing process, in addition to temperature abuse at the hospitals, are thought to have contributed to this outbreak. Conclusion: Raw vegetables, such as celery, are a potential source of STEC and present a risk to vulnerable populations. Recommendations from this outbreak include more frequent testing at the processor, a review of the chlorination and mincing process and a review of hospital food services practices to mitigate temperature abuse.

Patient- and Community-Oriented Primary Care Approaches for Health in Rural, Remote and Resource-Dependent Places: Insights for Eco-Social Praxis.

Accelerating ecological and societal changes require re-imagining the role of primary care and public health to address eco-social concerns in rural and remote places. In this narrative review, we searched literatures on: community-oriented primary care, patient-oriented research engagement, public health and primary care synergies, and primary care addressing social determinants of health. Our analysis was guided by questions oriented to utility for addressing concerns of social-ecological systems in rural, remote contexts characterized by a high degree of reliance on resource extraction and development (e.g., forestry, mining, oil and gas, fisheries, agriculture, ranching and/or renewables). We describe a range of useful frameworks, processes and tools that are oriented toward bolstering the resilience and engagement of both primary care and public health, though few explicitly incorporated considerations of eco-social approaches to health or broader eco-social context(s). In synthesizing the existing evidence base for integration between primary care and public health, the results signal that for community-oriented primary care and related frameworks to be useful in rural and remote community settings, practitioners are required to grapple with complexity, durable relationships, sustainable resources, holistic approaches to clinician training, Indigenous perspectives, and governance.

Musculoskeletal ultrasound: evaluation of the finger.

OBJECTIVE: Ultrasound is well suited for evaluating the superficial structures of the finger. The purpose of this video article is to review basic anatomy, scanning techniques, and sonographic appearance of the tendons, pulleys, and ligaments of the finger. Examples of pathologic conditions that can affect these structures will be shown. Please note that the large size of this file may result in several minutes of download time. CONCLUSION: Ultrasound is an established safe, efficient, and cost-effective method to evaluate structures in the finger. Knowledge of anatomy and technique is essential for scanning the finger accurately and effectively. The dynamic capability of ultrasound is especially helpful in evaluating for tendon and pulley injury and pathology.

saline-infused sonohysterography: tips for achieving greater success.

Saline-infused sonohysterography (SIS) may help improve visualization of the endometrium and endometrial cavity and assess tubal patency. Although most SIS procedures are straightforward, a variety of pitfalls may lead to an unsuccessful procedure or incomplete evaluation. SIS should be scheduled between days 4 and 10 of the patient's menstrual cycle, when the endometrium is at its thinnest, and physiologic changes during the secretory phase are not present. Performing preprocedure imaging serves many purposes, such as depicting hydrosalpinx, causes of uterine and adnexal tenderness, and pelvic inflammatory disease, as well as assessing the size and position of the uterus and the orientation of the cervix. It is important not to presume that fibroids are the cause of bleeding when the endometrium is obscured at preprocedure imaging. Obstacles to a successful procedure include issues related to patient anxiety and discomfort, which may be prevented or minimized at almost every step of the procedure. Inability to obtain access to the cervix is the most common cause of unsuccessful SIS; proper patient positioning in a semi-upright lithotomy position is important. Injection of air during any US-guided procedure may lead to shadowing that obscures the region of interest. Adequate distention of the endometrial cavity is crucial for successful SIS, and optimal positioning of the distended balloon may improve the degree of distention. However, poor distention may be indicative of an underlying pathologic condition. Knowledge of these pitfalls and the strategies to overcome them may prevent premature or unnecessary termination of an otherwise successful study.

Storylines of research on resource extraction and health in Canada: A modified metanarrative synthesis.

Patterns of research on resource extraction's health effects display problematic gaps and underlying assumptions, indicating a need to situate health knowledge production in the context of disciplinary, corporate and neocolonial influences and structures. This paper reports on a modified metanarrative synthesis of 'storylines' of research on resource extraction and health in the Canadian context. Peer-reviewed articles on mining or petroleum extraction and health published between 2000 and 2018 and dealing with Canadian populations or policies (n = 87) were identified through a systematic literature search. Coding identified main disciplinary traditions, methodologies and approaches for judging high-quality research. Underlying assumptions were analyzed in terms of models of health and well-being; resource extraction's political economic drivers; and representations of Indigenous peoples, territories and concerns. Findings included a preponderance of occupational and environmental health studies; frequent presentation of resource extraction without political economic antecedents, and as a major contributor to Canadian society; sustainable development aspirations to mitigate health impacts through voluntary private-sector governance activities; representations of Indigenous peoples and concerns ranging from complete absence to engagement with legacies of historical trauma and environmental dispossession; and indictment of corporate (especially asbestos industry) and government malfeasance in a subset of studies. Canada's world-leading mining sector, petroleum reserves and population health traditions, coupled with colonial legacies in both domestic and overseas mining and petroleum development, make these insights relevant to broader efforts for health equity in relation to resource extraction. They suggest a need for strengthened application of the precautionary principle in relation to resource extraction; nuanced attention to corporate influences on the production of health science; more profound challenges to dominant economic development models; and extension of well-intentioned efforts of researchers and policymakers working within flawed institutions.

Musculoskeletal ultrasound: evaluation of ankle tendons and ligaments.

OBJECTIVE: Ultrasound is well-established as a safe, efficient, and cost-effective method to evaluate superficial structures about the ankle. The purpose of this video article is to review the anatomy, scanning techniques, and sonographic appearance of the tendons and ligaments of the ankle. CONCLUSION: Ultrasound is well-suited for imaging the tendons and ligaments of the ankle. Knowledge of anatomy and bony landmarks is essential for scanning the ankle accurately and efficiently.

Implementation of Physical Activity Interventions in Rural, Remote, and Northern Communities: A Scoping Review.

Compared with urban centers, rural, remote, and northern communities face substantial health inequities and increased rates of noncommunicable disease fuelled, in part, by decreased participation in physical activity. Understanding how the unique sociocultural and environmental factors in rural, remote, and northern communities contribute to implementation of physical activity interventions can help guide health promotion policy and practice. A scoping review was conducted to map literature describing the implementation of physical activity interventions in rural, remote, and/or northern communities. Databases MEDLINE, PsycINFO, EMBASE, CINAHL, and SPORTDiscus were searched using a predetermined search strategy. Outcomes of interest included community demographics, program characteristics, intervention results, measures of implementation, and facilitators or barriers to implementation. A total of 1672 articles were identified from a search of databases, and 8 from a targeted hand search. After screening based on inclusion and exclusion criteria, 12 articles were summarized in a narrative review. Prominent barriers to physical activity program implementation included transportation, lack of infrastructure, sociocultural factors, and weather. Facilitators of program success included flexibility and creativity on the part of the implementation team, leveraging community relationships, and shared resources. Few papers reported on traditional implementation outcomes such as fidelity, dose, and quality. There is a lack of rigorous implementation evaluations of physical activity interventions delivered in rural, remote, or northern communities. Positive aspects of rural life, such as social cohesion and willingness to share resources, appear to contribute to successful program implementation.

Preparing for the future of public health: ecological determinants of health and the call for an eco-social approach to public health education.

As a collective organized to address the education implications of calls for public health engagement on the ecological determinants of health, we, the Ecological Determinants Group on Education (cpha.ca/EDGE), urge the health community to properly understand and address the importance of the ecological determinants of the public's health, consistent with long-standing calls from many quarters-including Indigenous communities-and as part of an eco-social approach to public health education, research and practice. Educational approaches will determine how well we will be equipped to understand and respond to the rapid changes occurring for the living systems on which all life-including human life-depends. We revisit findings from the Canadian Public Health Association's discussion paper on 'Global Change and Public Health: Addressing the Ecological Determinants of Health', and argue that an intentionally eco-social approach to education is needed to better support the health sector's role in protecting and promoting health, preventing disease and injury, and reducing health inequities. We call for a proactive approach, ensuring that the ecological determinants of health become integral to public health education, practice, policy, and research, as a key part of wider societal shifts required to foster a healthy, just, and ecologically sustainable future.

Move the north: evaluation of a regional stakeholder engagement initiative to support the development of a community-partnered physical activity research agenda.

BACKGROUND: Although it is generally accepted that engaging with members of the public contributes to more actionable and relevant research, there are a limited number of reported evaluations of community engagement initiatives. Certain populations, such as those with lower socioeconomic status and those who live in rural or dispersed communities, tend to face increased barriers to engagement. For researchers and community members alike, it is important to understand and evaluate engagement initiatives to support participatory research methods, particularly when working with underserved or hard to reach populations. METHODS: Over 2-days in October 2018, we hosted a Research Agenda Development Workshop and Physical Activity Summit with relevant researchers, health professionals, and community partners. The objectives of this initiative were to develop a physical activity research agenda based on community-identified priorities, create networking opportunities, and understand factors impacting physical activity participation in communities across northern British Columbia (BC). An evaluation plan was created early in the planning process to understand the reach of the event based on representation targets. Stakeholder satisfaction with the event was evaluated with a post-meeting survey. RESULTS: The event was successful in engaging community members from a broad geographic region with at least 90 people in attendance from 11 different northern BC communities, representing 46 different organizations. Meeting attendees indicated they were satisfied with the event and felt their perspectives were heard. To advance physical activity in the region, the most commonly desired outcome from the event was the need for ongoing communication channels to support knowledge translation and capacity building in the low-resourced communities of northern BC. There were some gaps in representation targets present at the event. Namely, there were a limited number of people representing Indigenous organizations, and the education and private sectors. CONCLUSIONS: This two-day event was successful at achieving its objectives and engaged a diverse group of stakeholders from a broad geographic region. The outcomes from this event are being used to develop a community-partnered physical activity research agenda and contribute to ongoing learning by the research team to understand contextual factors influencing physical activity in the communities of northern BC. This model of engagement could be used by other researchers interested in engaging with a diverse, multi-sector group of academics, health professionals and community members to support community-centered population health research.
