Rates of depression in Canada are rising, but a new CMAJ guideline advises against universal screening in primary care. The Canadian Task Force on Preventive Health Care found no evidence that routinely administering depression questionnaires to all adults improves outcomes and raised concerns about false positives, overdiagnosis, and strain on limited mental health resources.Dr. Eddy Lang, lead author of the guideline and professor of emergency medicine at the Cumming School of Medicine, University of Calgary, explains the rationale behind the Task Force’s recommendation. He describes how the review found no benefit from universal screening in improving depressive symptoms or quality of life and that commonly used questionnaires frequently misidentify patients, generating false positives and false negatives. Lang emphasizes that while physicians should remain attentive to patients’ mental health, questionnaires are not the answer to identifying depression in the general population.Dr. Jennifer Young, a family physician in Collingwood, Ontario, and past president of the Ontario College of Family Physicians, reflects on what this recommendation means for everyday practice. She agrees that routine screening would add little value, pointing out that vigilance and continuity of care already allow family doctors to identify depression through clinical judgment and patient relationships. She underscores that time spent on universal questionnaires could displace care for patients with other pressing needs.For physicians, the key takeaway is clear: be alert to signs of depression, especially in vulnerable patients, but don’t rely on blanket screening tools. Thoughtful conversation, familiarity with patients, and clinical intuition remain the best ways to identify those who need help.For more information from our sponsor, go to medicuspensionplan.comComments or questions?

Evidence is mounting that cannabis use can trigger first episode psychosis, particularly among young people. On this episode of the CMAJ Podcast, hosts Dr. Mojola Omole and Dr. Blair Bigham speak with researchers and a patient with lived experience about what the data show, who is most at risk, and how clinicians should respond.Bailey Peterson, a 26-year-old student from Mississauga, Ontario, describes how her cannabis consumption progressed from casual use to daily, all-day use of high-potency products. She recounts her experience with psychosis, the challenges of her hospitalization, and what she wishes she and her clinicians had known earlier.Sophie Li, a fourth-year medical student at the University of Ottawa and an author of the CMAJ article Cannabis and psychosis, explains how rates of schizophrenia associated with cannabis use disorder have risen sharply in recent years and notes that young men in their late teens and early 20s are most at risk. For women, the highest risk tends to occur later, in their late 20s and 30s. Dr. Marco Solmi, psychiatrist and medical director of On Track: The Champlain First Episode Psychosis Program, reviews the evidence supporting a causal link between cannabis and psychosis and discusses how clinicians can distinguish cannabis-induced psychosis from schizophrenia, as well as approaches to treatment and patient education.For physicians, the takeaway is clear: cannabis use—particularly before age 25—carries worrisome psychiatric risks, and psychosis can occur even without very high levels of consumption. Detailed cannabis histories, psychoeducation, and early counseling should be part of routine care for patients at risk of psychosis.Comments or questions?

Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy’s disease, is a rare, progressive neuromuscular disorder that is often misdiagnosed and diagnosed late. A new CMAJ guideline offers Canadian-specific recommendations for its recognition and management.On this episode we hear from Richard Paul, a former bus driver from Saskatoon, who recalls how his symptoms began suddenly with an inability to bite into a sandwich and, over the years, progressed so gradually he barely noticed the loss of strength. His experience captures both the slow, inexorable progression of SBMA and the uncertainty of living without a diagnosis for decades.Mr. Paul was finally diagnosed by Dr. Kerri Schellenberg, a neuromuscular neurologist at the University of Saskatchewan and lead author of the guideline. She explains the clinical hallmarks of SBMA, its overlap with conditions such as ALS, and the non-motor manifestations that require attention. She also discusses the higher prevalence among Indigenous populations in Canada and how her team worked with a community Guiding Circle to ensure the recommendations reflect culturally appropriate care.For physicians, the guideline provides practical direction to support earlier recognition, timely referral, and multidisciplinary management. While there is no cure, coordinated care can significantly improve quality of life for people living with SBMA.For more information from our sponsor, go to md.ca/md-differenceComments or questions?

Homelessness among pregnant and parenting people in Canada is rising, with grave consequences for both parents and children. On this episode of the CMAJ Podcast, Dr. Mojola Omole and Dr. Blair Bigham explore the scope of the problem and the supports that can improve outcomes for parents and children.Dr. Stéphanie Manoni-Millar, co-author of the CMAJ commentary Tackling the crisis of homelessness amongst pregnant and parenting people in Canada, explains who is most affected and what risks they face. She describes a predominantly young population, many of whom are homeless or experiencing precarious housing. She highlights the health consequences for children, including developmental delays, infections, and increased rates of anxiety and depression, and stresses the importance of affordable housing and integrated services to support families.Nerina Chiodo, a social worker in Toronto with MotherCraft Breaking the Cycle, shares insights from more than two decades of supporting pregnant people who are homeless. She describes what stability can look like when housing, addiction treatment, mental health services, and social supports are coordinated, an approach often described as wraparound care. Chiodo also reflects on the stigma many of her clients face in medical settings and underscores the importance of small acts of validation and compassion from clinicians.Both guests emphasized that people experiencing homelessness during pregnancy often want to parent and demonstrate resilience despite immense challenges. They urged clinicians to approach this population without stigma, to recognize the risks faced by children, and to understand how even brief, supportive interactions can influence whether patients return for care.Comments or questions?

Smoking remains the leading cause of preventable disease and death in Canada. A new clinical practice guideline published in CMAJ on tobacco smoking cessation outlines evidence-based behavioural and pharmacological interventions to help patients quit. On this episode of the CMAJ Podcast, Dr. Mojola Omole and Dr. Blair Bigham speak with Dr. Eddy Lang, co-author of the guideline, and Dr. Andrew Pipe, a pioneer in smoking cessation research and practice, about how clinicians can better support patients ready to stop smoking.Dr. Eddy Lang, an emergency physician and professor at the Cumming School of Medicine, describes how the Canadian Task Force on Preventive Health  assessed a wide range of interventions to make sense of a complex evidence base. He outlines the strong recommendations in favour of pharmacological therapies such as nicotine replacement therapy, bupropion, varenicline, and cytosine, as well as behavioural interventions including counselling, group therapy, and quit lines. He also explains the conditional recommendation against e-cigarettes, citing limited long-term safety data and concerns about normalizing their use among youth.Dr. Andrew Pipe, professor of medicine at the Ottawa Heart Institute and co-creator of the Ottawa Model of Smoking Cessation, offers practical guidance for everyday practice. He highlights how a state-of-the-art smoking cessation intervention can be delivered in as little as 26 seconds. This brief approach is non-judgemental, empathetic, and emphasizes that help is available whenever the patient is ready.He also stresses that clinicians should treat cessation pharmacotherapy like any other chronic disease medication—titrated to patient response and continued as long as needed. Pipe emphasizes that nicotine replacement therapy is often underdosed, which undermines its effectiveness. He encourages physicians to combine long-acting patches with rapid-acting forms such as gum or lozenges, and to adjust dosing based on patient comfort, allowing individuals to guide their own titration.This episode underscores that even brief encounters can open the door to meaningful change for patients ready to stop smoking. Asking about smoking status, offering practical, evidence-based assistance, and prescribing cessation therapies in sufficient doses can effectively help patients quit.For more information from our sponsor, go to md.ca/md-differenceComments or questions?

—This is an encore presentation of an episode previously published June 30—On this episode of the CMAJ Podcast, hosts Dr. Mojola Omole and Dr. Blair Bigham speak with two authors of the latest “Hypertension Canada guideline for the diagnosis and treatment of hypertension in adults in primary care”The discussion reflects a shared urgency: despite past successes, Canada’s hypertension control rates are declining. The new guidelines aim to reverse this trend by simplifying diagnosis and treatment for frontline clinicians.Dr. Rémi Goupil, a nephrologist and clinician researcher at Sacré-Cœur Hospital in Montreal, and Dr. Greg Hundemer, a nephrologist and clinician scientist at The Ottawa Hospital, explain that the updated guideline is deliberately designed for primary care providers. They highlight key shifts: lowering the diagnostic threshold for hypertension to  ≥ 130/80 mm Hg, simplifying blood pressure targets, and emphasizing accurate, standardized measurement techniques both in clinic and at home. The guidelines were created with input from a majority-primary care committee—including family physicians, nurses, pharmacists, and patient partners—to ensure clinical applicability.Together, the panel outlines a streamlined nine-step treatment algorithm, emphasizing combination therapy as first-line pharmacologic management. They explain the evidence supporting ARB–thiazide combinations, discuss cost considerations for drug selection, and address adherence challenges. They also explore red flags for secondary hypertension and how the algorithm supports—but does not replace—clinical judgment.For physicians, this guideline offers a clear and practical roadmap: measure blood pressure correctly, aim for systolic pressure below 130 mm Hg, and use the simplified treatment sequence to improve adherence and outcomes. Designed to be easy to implement, the new approach aims to empower primary care providers to act with confidence.Comments or questions?

The rising global burden of mosquito-borne viral infections has important implications for Canadian clinicians—particularly those assessing febrile patients returning from tropical and subtropical regions. On this episode of the CMAJ Podcast, infectious diseases specialists Dr. Maxime Billick and Dr. Stephen Vaughan explain what clinicians need to watch for as these viruses expand their geographic reach. Dr. Billick is the lead author of Five things to know about dengue, and Dr. Vaughan is the lead author of Five things to know about Oropouche virus, both published in CMAJ.Dr. Maxime Billick describes the dramatic surge in dengue cases in 2024 and outlines the major drivers behind the virus’s global spread. She explains the urban-dwelling mosquito vectors that make dengue difficult to contain, discusses the virus’s four serotypes, and emphasizes the risk of antibody-dependent enhancement with reinfection. She reviews key clinical warning signs, diagnostic tests, and why identifying dengue—despite limited treatment options—still matters for patient counselling and care.Dr. Stephen Vaughan introduces the less common but emerging Oropouche virus. He explains its current geographic range, including recent Canadian travel-related cases, and the role of biting midges in its transmission. Vaughan highlights early evidence of possible sexual transmission and the potential risks for fetal neurological complications if infection occurs during pregnancy. He also discusses symptom recurrence and what physicians should consider when counselling patients who may have been exposed.Physicians should consider dengue and Oropouche virus in febrile returned travellers and prioritize preventive counselling before travel. Identifying the virus may not change treatment, but it can shape long-term risk awareness and help prevent future complications.For more information from our sponsor, go to MedicusPensionPlan.comComments or questions?
