Screening and Diagnosis of Celiac Disease
Celiac disease (CD) is an immune mediated injury to the small intestine that is caused by ingestion of gluten (a name for multiple proteins in wheat, rye and barley) in genetically susceptible individuals. In Canada, CD occurs in approximately 1:100 people. The disease can be difficult to diagnose because it presents with a variety of symptoms (see Table) at any point in life. Prevalence of CD is higher in specific associated conditions. Source: Canadian Celiac Association
Setting up a temporary home office
Working at home in the middle of a COVID-19 pandemic means having no time and little opportunity to set up ergonomically sound workstations. So what can office workers do to make their kitchen table workspaces as comfortable as possible? We turn to Dr. Dwayne Van Eerd for advice. Source: Institute for Work & Health

Telework / Remote Work / Working From Home
It is becoming more and more common for people to do at least some of their regular work from home or another location instead of going into the office. Technology has made it possible for a worker to stay at home but be connected to the office by telephone, computer, and internet. This type of arrangement is known by many terms, including telework, telecommuting, remote work, or working from home. Source: Canadian Centre for Occupational Health and Safety
What is a lone worker alarm and how can it help protect employees?
Managing lone workers in health and safety can be a challenge and with 2020 bringing about a new focus on homeworking, it is no longer select professions that have to worry about how their workers are coping when they are not being supervised. Source: HSE Network
