KEY POINTS

This guideline update reflects substantial changes in the literature on diagnosis and treatment of Parkinson disease, and adds information on palliative care.

Impulse control disorders can develop in a person with Parkinson disease who is on any dopaminergic therapy at any stage in the disease course, especially for those taking dopamine agonists.

Advanced therapies like deep brain stimulation and intrajejunal levodopa-carbidopa gel infusion are now routinely used in Parkinson disease to manage motor symptoms and fluctuations.

Evidence exists to support early institution of exercise at the time of diagnosis of Parkinson disease, in addition to the clear benefit now shown in those with well-established disease.

Palliative care requirements of people with Parkinson disease should be considered throughout all phases of the disease, which includes an option of medical assistance in dying.

Parkinson disease is chronic and progressive in nature, decreasing the quality of life for both patients with the disease and their caregivers and placing an onerous economic burden on society.1

The first Canadian guideline on Parkinson disease was published in 2012.2 Since that guideline, there have been substantial advances in the literature on the disease, particularly with respect to diagnostic criteria and treatment options. Parkinson Canada undertook to update the existing guideline to reflect these advances, as well as to add information on palliative care.

With the aim of enhancing care for all Canadians with Parkinson disease, this guideline is based on the best published evidence, involves expert consensus when there is a lack of evidence, offers practical clinical advice, takes patient choice and informed decision-making into account and is relevant to the Canadian health care system. The guideline has been divided into 5 main sections to improve the ease of use: communication, diagnosis and progression, treatment, nonmotor features and palliative care. The full guideline is available in Appendix 1, at www.cmaj.ca/lookup/suppl/doi:10.1503/cmaj.181504/-/DC1.

Hidradenitis suppurativa is a chronic inflammatory disease characterised by painful, deep-seated nodules, abscesses, and draining tunnels in the skin of axillary, inguinal, genitoanal, or inframammary areas. In recent years, the body of knowledge in hidradenitis suppurativa has advanced greatly. This disorder typically starts in the second or third decade of life. The average worldwide prevalence is 1% but varies geographically. Hidradenitis suppurativa has a profound negative effect on patients' quality of life and on the gross value added to society. Comorbidities (eg, metabolic syndrome, inflammatory arthritis, and inflammatory bowel disease) frequently accompany skin alterations, because of systemic inflammation. Pathogenesis of hidradenitis suppurativa is complex and includes innate immune mechanisms (eg, macrophages, neutrophils, IL-1β, tumour necrosis factor [TNF], and granulocyte colony-stimulating factor), T-cell mechanisms (eg, IL-17 and IFN-γ), and B-cell mechanisms (eg, associated with dermal tertiary lymphatic structures and autoantibodies). Chronic inflammation leads to irreversible skin damage with tunnel formation and morbid scarring. Current treatment includes drug therapy (for the initial, purely inflammatory phase), combined drug and surgical therapy (for the destructive phase), or surgery alone (for the burnout phase). The first systemic therapies approved for hidradenitis suppurativa targeting TNF (adalimumab) and IL-17 (secukinumab and bimekizumab) have expanded drug therapy options for moderate-to-severe disease, which were previously mainly restricted to oral antibiotics. Moreover, there is a robust pipeline of immunomodulatory drugs in various stages of development for hidradenitis suppurativa. Aims of management should include early intervention to prevent irreversible skin damage, adequate control of symptoms including pain, and mitigation of extra-cutaneous comorbidities, all requiring early diagnosis and an interdisciplinary, holistic and personalised approach.

What Is Hospice?

Author/s: 
Vanessa Wagner, Adam Marks

Hospice is a specialized model of medical care for people with terminal illness.

The goal of hospice is to provide compassionate care to maximize a person’s comfort and quality of life during the natural dying process. Hospice care teams are composed of doctors, nurses, social workers, chaplains, and other individuals who work together to address the physical, emotional, social, and spiritual needs of people with a terminal illness and to support their families. This generally includes alleviating symptoms (such as pain, shortness of breath, or anxiety), establishing a comfortable and peaceful environment, and facilitating meaningful time with loved ones.

Sexual Dysfunction in Women

Author/s: 
Susan R Davis

The Clinical Problem
Because there is no universal definition of normal sexual function, what constitutes sexual difficulty is determined by a person’s subjective definition of unsatisfactory sexual well-being. The condition is usually described as unsatisfactory interest, arousal, orgasm, or other aspects of sexuality (e.g., sexual self-image), and the symptoms often coexist. The term “sexual dysfunction” is used when at least one of the symptoms is of substantial concern to the affected person. Sexual dysfunction negatively affects mental health, vitality, and social functioning and has an overall effect on quality of life that is of similar magnitude to that associated with chronic back pain or diabetes.

Émélie Braschi, Samantha S Moe

Clinical question
Do self-fitted hearing aids improve hearing for adults with mild to moderately severe hearing loss?

Bottom line
Some, not all, direct-to-consumer (DTC) self-fitted hearing aids are likely comparable to audiogram-fitted conventional hearing aids and tend to cost less.

Semaglutide vs Endoscopic Sleeve Gastroplasty for Weight Loss

Author/s: 
Haseeb, M., Chhatwal, J., Xiao, J., Jirapinyo, P., Thompson, C.C.

Importance: Obesity is a disease with a large socioeconomic burden. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive endoscopic bariatric procedure with wide global adoption. More recently, new weight-loss medications, such as glucagon-like peptide-1 receptor agonists (eg, semaglutide), have attracted increased attention due to their efficacy. However, their cost-effectiveness over an extended period compared with ESG is a critical gap that needs to be better explored for informed health care decision-making.

Objective: To assess the cost-effectiveness of semaglutide compared with ESG over 5 years for individuals with class II obesity.

Design, setting, and participants: This economic evaluation study, conducted from September 1, 2022, to May 31, 2023, used a Markov cohort model to compare ESG and semaglutide, with a no-treatment baseline strategy. The study comprised adult patients in the US health care system with class II obesity (body mass index [BMI] of 35-39.9). The base case was a 45-year-old patient with class II obesity (BMI of 37). Patients undergoing ESG were subjected to risks of perioperative mortality and adverse events with resultant costs and decrement in quality of life.

Interventions: Strategies included treatment with semaglutide and ESG.

Main outcomes and measures: Costs (2022 US dollars), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) with a willingness-to-pay threshold of $100 000/QALY. A 5-year time horizon with a cycle length of 1 month with a 3% discount rate was used. Probabilities, costs, and quality-of-life estimates of the model were derived from published literature. One-way, 2-way, and probabilistic sensitivity analyses were also performed.

Results: The model found that ESG was more cost-effective than semaglutide over a 5-year time horizon, with an ICER of -$595 532/QALY. Endoscopic sleeve gastroplasty added 0.06 QALYs and reduced total cost by $33 583 relative to semaglutide. The results remained robust on 1-way and probabilistic sensitivity analyses. Endoscopic sleeve gastroplasty sustained greater weight loss over 5 years vs semaglutide (BMI of 31.7 vs 33.0). To achieve nondominance, the annual price of semaglutide, currently $13 618, would need to be $3591.

Conclusions and relevance: This study suggests that ESG is cost saving compared with semaglutide in the treatment of class II obesity. On price threshold analyses, a 3-fold decrease in the price of semaglutide is needed to achieve nondominance.

Background: Fragility fractures are a major health concern for older adults and can result in disability, admission to hospital and long-term care, and reduced quality of life. This Canadian Task Force on Preventive Health Care (task force) guideline provides evidence-based recommendations on screening to prevent fragility fractures in community-dwelling individuals aged 40 years and older who are not currently on preventive pharmacotherapy.

Methods: We commissioned systematic reviews on benefits and harms of screening, predictive accuracy of risk assessment tools, patient acceptability and benefits of treatment. We analyzed treatment harms via a rapid overview of reviews. We further examined patient values and preferences via focus groups and engaged stakeholders at key points throughout the project. We used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to determine the certainty of evidence for each outcome and strength of recommendations, and adhered to Appraisal of Guidelines for Research and Evaluation (AGREE), Guidelines International Network and Guidance for Reporting Involvement of Patients and the Public (GRIPP-2) reporting guidance.

Recommendations: We recommend "risk assessment-first" screening for prevention of fragility fractures in females aged 65 years and older, with initial application of the Canadian clinical Fracture Risk Assessment Tool (FRAX) without bone mineral density (BMD). The FRAX result should be used to facilitate shared decision-making about the possible benefits and harms of preventive pharmacotherapy. After this discussion, if preventive pharmacotherapy is being considered, clinicians should request BMD measurement using dual-energy x-ray absorptiometry (DXA) of the femoral neck, and re-estimate fracture risk by adding the BMD T-score into FRAX (conditional recommendation, low-certainty evidence). We recommend against screening females aged 40-64 years and males aged 40 years and older (strong recommendation, very low-certainty evidence). These recommendations apply to community-dwelling individuals who are not currently on pharmacotherapy to prevent fragility fractures.

Interpretation: Risk assessment-first screening for females aged 65 years and older facilitates shared decision-making and allows patients to consider preventive pharmacotherapy within their individual risk context (before BMD). Recommendations against screening males and younger females emphasize the importance of good clinical practice, where clinicians are alert to changes in health that may indicate the patient has experienced or is at higher risk of fragility fracture.

Diagnosis and management of endometriosis

Author/s: 
Allaire, Catherine, Bedaiwy, Mohamed, Yong, Paul

Endometriosis is a chronic condition defined by the presence of endometrial-like tissue outside of the uterus, which can lead to estrogen-driven inflammation. The extent of disease can be highly variable, ranging from minimal peritoneal deposits to deep disease that can invade into the bowel, bladder and ureter and, more rarely, spread to extrapelvic (e.g., cutaneous, thoracic) sites. Endometriosis is a complex disease that has considerable impact on the quality of life of those affected and that has no cure. It remains poorly understood. We review the epidemiology, pathophysiology, diagnosis and management of endometriosis, based on the best available evidence and clinical guidelines

Heart Failure With Preserved Ejection Fraction

Author/s: 
Redfield, Margaret, Borlaug, Barry

Importance Heart failure with preserved ejection fraction (HFpEF), defined as HF with an EF of 50% or higher at diagnosis, affects approximately 3 million people in the US and up to 32 million people worldwide. Patients with HFpEF are hospitalized approximately 1.4 times per year and have an annual mortality rate of approximately 15%.

Observations Risk factors for HFpEF include older age, hypertension, diabetes, dyslipidemia, and obesity. Approximately 65% of patients with HFpEF present with dyspnea and physical examination, chest radiographic, echocardiographic, or invasive hemodynamic evidence of HF with overt congestion (volume overload) at rest. Approximately 35% of patients with HFpEF present with “unexplained” dyspnea on exertion, meaning they do not have clear physical, radiographic, or echocardiographic signs of HF. These patients have elevated atrial pressures with exercise as measured with invasive hemodynamic stress testing or estimated with Doppler echocardiography stress testing. In unselected patients presenting with unexplained dyspnea, the H2FPEF score incorporating clinical (age, hypertension, obesity, atrial fibrillation status) and resting Doppler echocardiographic (estimated pulmonary artery systolic pressure or left atrial pressure) variables can assist with diagnosis (H2FPEF score range, 0-9; score >5 indicates more than 95% probability of HFpEF). Specific causes of the clinical syndrome of HF with normal EF other than HFpEF should be identified and treated, such as valvular, infiltrative, or pericardial disease. First-line pharmacologic therapy consists of sodium-glucose cotransporter type 2 inhibitors, such as dapagliflozin or empagliflozin, which reduced HF hospitalization or cardiovascular death by approximately 20% compared with placebo in randomized clinical trials. Compared with usual care, exercise training and diet-induced weight loss produced clinically meaningful increases in functional capacity and quality of life in randomized clinical trials. Diuretics (typically loop diuretics, such as furosemide or torsemide) should be prescribed to patients with overt congestion to improve symptoms. Education in HF self-care (eg, adherence to medications and dietary restrictions, monitoring of symptoms and vital signs) can help avoid HF decompensation.

Conclusions and Relevance Approximately 3 million people in the US have HFpEF. First-line therapy consists of sodium-glucose cotransporter type 2 inhibitors, exercise, HF self-care, loop diuretics as needed to maintain euvolemia, and weight loss for patients with obesity and HFpEF.

Individualized antidepressant therapy in patients with major depressive disorder: Novel evidence-informed decision support tool

Author/s: 
Chin, T., Huyghebaert, T., Svrcek, C., Oluboka, O.

Objective: To introduce a visual clinical decision support tool to assist with individualizing first-line antidepressant pharmacotherapy for adults with major depressive disorder (MDD) in a Canadian context.

Sources of information: A literature review was conducted with Google Scholar, PubMed, the Cochrane Database of Systematic Reviews, and Trip Pro using the MeSH headings depression, antidepressive agents, primary care, practice patterns, medication adherence, and decision making, shared.

Main message: Major depressive disorder affects about 4.7% of Canadians annually and is a prevalent condition encountered and diagnosed in primary care. Untreated depression is associated with decreased quality of life, increased risk of suicide, and worsening physical health outcomes when depression co-occurs with other chronic medical conditions. In a network meta-analysis, antidepressant medications (such as selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, bupropion, and vortioxetine) reduced depressive symptoms by 50% or more when compared with placebo in acute treatment of adults with moderate to severe MDD. Poor treatment adherence and high discontinuation rates limit MDD treatment success. Factors such as strong therapeutic alliances between patients and prescribers, collaborative care, patient education, and supportive self-management have been shown to enhance treatment adherence. The most recent Canadian Network for Mood and Anxiety Treatments depression treatment guidelines (published in 2016) suggest 15 different first-line antidepressant medication options for the treatment of MDD. There is a need for evidence-informed decision support aids to individualize antidepressant therapy to treat patients diagnosed with MDD.

Conclusion: Recent studies on antidepressants have indicated no single antidepressant is superior to others in treating patients with MDD. This suggests there may be opportunities to enhance treatment adherence and success by tailoring antidepressant therapy to align with each patient's preferences. The Antidepressant Decision Support Tool was developed to help prescribers and adult patients engage in shared decision making to select an individualized and optimal first-line antidepressant for the treatment of acute MDD.
