Nutrition concerns are prevalent in individuals with Amyotrophic Lateral Sclerosis (ALS). Despite the prevalence of nutrition concerns, few data are available on perceptions and experiences of nutrition interventions in individuals with ALS and their caregivers; this study aimed to collect this information. An online survey was developed and hosted on Survey Monkey.

In this article we review complications to the peripheral nervous system that occur as a consequence of viral infections, with a special focus on complications of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). We discuss neuromuscular complications in three broad categories; the direct consequences of viral infection, autoimmune neuromuscular disorders provoked by viral infections, and chronic neurodegenerative conditions which have been associated with viral infections. We also include discussion of neuromuscular disorders that are treated by immunomodulatory therapies, and how this affects patient susceptibility in the current context of the coronavirus disease 2019 (COVID-19) pandemic.

Article Synopsis
  • A study was conducted to assess genetic testing practices at ALS clinics across Canada, using surveys and interviews with clinicians from 27 clinics.
  • Results showed that 93% of clinics regularly test for familial ALS, but only 33% do so for sporadic ALS, highlighting significant barriers such as treatment impact perception, approval challenges, and inadequate genetic counseling access.
  • Findings indicate that genetic testing access varies widely, with an average wait time of 10 months to see a genetic counselor, and calls for improved testing practices to ensure equitable healthcare delivery for ALS patients.

Article Synopsis
  • Spinobulbar muscular atrophy (SBMA) is a rare neuromuscular disorder primarily affecting males, particularly those of Indigenous descent in Saskatchewan, leading to significant weakness and androgen insensitivity.
  • A study estimated the prevalence of SBMA in this group at 14.7 per 100,000, suggesting it may be the highest recorded globally, although this figure is likely conservative.
  • Unique haplotypes were identified among Indigenous participants, indicating a potential founder effect for the disease, warranting further research to confirm these findings.

Background: Spinal Muscular Atrophy (SMA) is a rare disease that affects 1 in 11 000 live births. Recent developments in SMA treatments have included new disease-modifying therapies that require high quality data to inform decisions around initiation and continuation of therapy. In Canada, there are no nationally agreed upon outcome measures (OM) used in adult SMA.

Article Synopsis
  • A study was conducted to assess the safety, dose response, and initial efficacy of a treatment for patients with amyotrophic lateral sclerosis (ALS) over 12 weeks.
  • A total of 458 patients were enrolled, with results showing no significant improvements in the primary endpoint of slow upright vital capacity (SVC) or secondary measures like the ALS Functional Rating Scale and muscle strength mega-score during the 12 weeks.
  • While the main analysis did not reach statistical significance, trends indicated potential benefits for active treatment compared to placebo, and the treatment was generally well tolerated, with minor side effects and reversible liver and kidney issues noted.

Background: Spinal muscular atrophy (SMA) is a devastating rare disease that affects individuals regardless of ethnicity, gender, and age. The first-approved disease-modifying therapy for SMA, nusinursen, was approved by Health Canada, as well as by American and European regulatory agencies following positive clinical trial outcomes. The trials were conducted in a narrow pediatric population defined by age, severity, and genotype.

Article Synopsis
  • - Saskatchewan has a significant issue with diagnosing amyotrophic lateral sclerosis (ALS), historically reported with a delay of 27 months; however, recent research found a mean delay of 16.6 months across a larger patient population.
  • - A study review of 171 patients in Saskatoon examined whether rural patients experience longer diagnostic delays due to distance from neurologists at tertiary centers, but results showed no significant differences between urban and rural patients.
  • - The research concluded that there were no notable variations in diagnostic delays or access to ALS care between urban and rural populations, suggesting the need for further studies to confirm these findings.

Spinal and Bulbar Muscular Atrophy (SBMA) is caused by the extension of the polyglutamine tract within the androgen receptor (AR) gene, and results in a multisystem presentation, including the degeneration of lower motor neurons. The androgen receptor (AR) is known to modulate the expression of endogenous retrovirus-K (ERVK), a pathogenic viral genomic symbiont. Since ERVK is associated with motor neuron disease, such as Amyotrophic Lateral Sclerosis (ALS), we sought to determine if patients with SBMA exhibit evidence of ERVK reactivation.

Background: Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease resulting in muscle weakness, dysarthria and dysphagia, and ultimately respiratory failure leading to death. Half of the ALS patients survive less than 3 years, and 80% of the patients survive less than 5 years. Riluzole is the only approved medication in Canada with randomized controlled clinical trial evidence to slow the progression of ALS, albeit only to a modest degree.

Purpose: Multidisciplinary clinics (MDC) have become the standard of care for management of amyotrophic lateral sclerosis (ALS). No studies however, have captured patients' perspectives during a transition to ALS MDCs. Recently, an ALS MDC emerged from a single-physician clinic in Saskatoon, Canada, providing patients with a unique exposure to two different models of care.

Objective: This retrospective study reviewed hospital and intensive care unit (ICU) admissions for patients with amyotrophic lateral sclerosis (ALS) in Saskatoon, Canada, between 2005 and 2017. The purpose was to understand hospital utilization and admission patterns for patients with ALS in the absence of coordinated multidisciplinary care.

Methods: Hospital/ICU admissions were detected at two hospitals in Saskatoon using the International Classification of Diseases (ICD-10) coding for ALS.

The manner in which physicians deliver difficult diagnoses is an area of discontent for patients with amyotrophic lateral sclerosis (ALS). The American Academy of Neurology's Practice Parameter for care of the ALS Patient recommended teaching and evaluating strategies for disclosing the diagnosis (10). Our objective was to examine residents' ability in and perceptions of communicating the diagnosis of ALS.

We report a 64-year-old female with predominantly bulbar amyotrophic lateral sclerosis who experienced 'roaring' in her ears. She was diagnosed with patulous Eustachian tube, which is presumed to occur secondary to bulbar weakness. The roaring adversely affected the management of her ALS by impairing her ability to tolerate BiPaP.

Objective: : To assess the validity and reliability of an office-based surrogate measure of lumbar spine-stabilization endurance capability; to establish norms and reliability in an asymptomatic group; and to compare their measures with those from a group of chronic mechanical low-back pain patients.

Design: : Eight healthy subjects participated in the tool-validation portion of the study that consisted of surface electromyographic (EMG) measurements of core muscle activation during prone and supine bridging. Subsequently, normative and test-retest reliability measures of prone and supine bridging duration were recorded from 43 subjects without back pain and were compared with those of 32 subjects with chronic mechanical low-back pain.
