Background: Racialised trainees in Canada and the USA continue to disproportionately experience discrimination and harassment in learning environments despite equity, diversity, and inclusion (EDI) reform efforts. Using critical approaches to understand what problems have been conceptualised and operationalised as EDI issues within postgraduate medical education (PGME) is important to inform ongoing learning environment reform in resident training.

Methods: We conducted a critical narrative review of EDI literature from 2009-2022 using critical race theory (CRT) and the concept of intersectionality to analyse how issues of discrimination in PGME have been studied.

Article Synopsis
  • Red blood cell transfusions can be beneficial but come with potential risks, necessitating guidelines for their use in both adults and children.
  • Studies involved numerous randomized controlled trials which found that restrictive transfusion strategies (transfusing at lower hemoglobin thresholds) generally do not harm patient outcomes for most populations.
  • Recommendations include using restrictive strategies for stable adult patients, advising transfusions at hemoglobin levels below 7 g/dL, with some exceptions based on specific patient conditions like cardiac or orthopedic surgeries.

Article Synopsis
  • Ivacaftor, a drug for cystic fibrosis (CF), significantly improves lung function and weight gain, but its long-term effects on weight, resting energy expenditure (REE), and body composition need more investigation.* -
  • A study involving 18 participants showed that after 24 months of ivacaftor treatment, there was a noticeable increase in BMI and fat mass, but no change in fat-free mass or REE.* -
  • The findings suggest that weight gain in patients on ivacaftor is mostly due to increased fat mass, emphasizing the importance of diet and exercise counseling for those undergoing CFTR-modulating treatment.*

Article Synopsis
  • The classification of multiple sclerosis (MS) was originally established in 1996 and revised in 2013 to include different types like clinically isolated syndrome and relapsing-remitting MS, with a focus on activity levels.
  • The proposed expansion of classification includes additional pathological processes such as chronic inflammation and neuroaxonal degeneration to better differentiate MS phenotypes that may look the same clinically but have different underlying mechanisms.
  • This refined approach aims to enhance prognostication, personalized treatment, and clinical trial design, ultimately leading to better monitoring and understanding of MS progression.

Nutr Clin Pract

December 2022

Canadian Malnutrition Task Force, Edmonton, Alberta, Canada.

Lack of a standardized method of identifying and defining pediatric malnutrition has led to an inability to fully understand the prevalence of and impact that malnutrition has on pediatric patients and the healthcare system. The Subjective Global Nutritional Assessment (SGNA) is an assessment tool meant to determine presence and severity of malnutrition in pediatric populations. However, the anthropometric section of the tool contains some out-dated parameters.

The complement system is a tightly controlled signaling network that plays a role in innate immune surveillance. However, abnormal signaling through this pathway contributes to tissue damage in several inflammatory, autoimmune, and degenerative diseases. Myasthenia gravis (MG) and neuromyelitis optica spectrum disorders (NMOSD) have complement dysfunction at the core of pathogenesis, providing a strong rationale for therapeutic targeting of complement components.

Introduction: One of the current challenges in long-term care homes (LTCH) is to identify the optimal model of care, which may include specialty physicians, nursing staff, person support workers, among others. There is currently no consensus on the complement or scope of care delivered by these providers, nor is there a repository of studies that evaluate the various models of care. We conducted a rapid scoping review to identify and map what care provider models and interventions in LTCH have been evaluated to improve quality of life, quality of care, and health outcomes of residents.

The archaic definition and registration processes for stillbirth currently prevalent in Canada impede both clinical care and public health. The situation is fraught because of definitional problems related to the inclusion of induced abortions at ≥20 weeks' gestation as stillbirths: widespread uptake of prenatal diagnosis and induced abortion for serious congenital anomalies has resulted in an artefactual temporal increase in stillbirth rates in Canada and placed the country in an unfavourable position in international (stillbirth) rankings. Other problems with the Canadian stillbirth definition and registration processes extend to the inclusion of fetal reductions (for multi-fetal pregnancy) as stillbirths, and the use of inconsistent viability criteria for reporting stillbirth.
