RESUMEN
Sex (the physical and physiologic effects resulting from having specific combinations of sex chromosomes) and gender (sex-associated behaviours, expectations, identities, and roles) significantly affect the course of inflammatory bowel disease (IBD) and the experience of living with IBD. Sex-influenced physiologic states, like puberty, the menstrual cycle, pregnancy, and andropause/menopause may also impact and be impacted by IBD. While neither Crohn's disease nor ulcerative colitis is commonly considered sex-determined illnesses, the relative incidence of Crohn's disease and ulcerative colitis between males and females varies over the life cycle. In terms of gender, women tend to use healthcare resources at slightly higher rates than men and are more likely to have fragmented care. Women are more commonly prescribed opioid medications and are less likely than men to undergo colectomy. Women tend to report lower quality of life and have higher indirect costs due to higher rates of disability. Women are also more likely to take on caregiver roles for children with IBD. Women with IBD are more commonly burdened with adverse mental health concerns and having poor mental health has a more profound impact on women than men. Pregnant people with active IBD have higher rates of adverse outcomes in pregnancy, made worse in regions with poor access to IBD specialist care. The majority of individuals with IBD in Canada do not have access to a pregnancy-in-IBD specialist; access to this type of care has been shown to allay fears and increase knowledge among pregnant people with IBD.
RESUMEN
Rates of inflammatory bowel disease (IBD) in Canadian children and adolescents are among the highest in the world, and the incidence is rising most rapidly in children under five years of age. These young children may have either a typical form of IBD with multi-factorial aetiology, or they may have a monogenic form. Despite the growing number of children in Canada living with this important chronic disease, there are few available medical therapies approved by Health Canada due to the omission of children from most clinical trials of newly developed biologics. As a result, off-label use of medications is common, and physicians have learned to use existing therapies more effectively. In addition, most Canadian children are treated in multidisciplinary, specialty clinics by physicians with extra training or experience in IBD, as well as specialist nurses, dietitians, mental health care providers and other allied health professionals. This specialized clinic approach has facilitated cutting edge research, led by Canadian clinicians and scientists, to understand the causes of IBD, the optimal use of therapies, and the best ways to treat children from a biopsychosocial perspective. Canadians are engaged in work to understand the monogenic causes of IBD; the interaction between genes, the environment, and the microbiome; and how to address the mental health concerns and medical needs of adolescents and young adults transitioning from paediatric to adult care.
RESUMEN
Pulmonary fibrosis is a chronic, fibrotic lung disease affecting 3 million people worldwide. The ACE2/Ang-(1-7)/MasR axis is of interest in pulmonary fibrosis due to evidence of its anti-fibrotic action. Current scientific evidence supports that inhibition of ACE2 causes enhanced fibrosis. ACE2 is also the primary receptor that facilitates the entry of SARS-CoV-2, the virus responsible for the current COVID-19 pandemic. COVID-19 is associated with a myriad of symptoms ranging from asymptomatic to severe pneumonia and acute respiratory distress syndrome (ARDS) leading to respiratory failure, mechanical ventilation, and often death. One of the potential complications in people who recover from COVID-19 is pulmonary fibrosis. Cigarette smoking is a risk factor for fibrotic lung diseases, including the idiopathic form of this disease (idiopathic pulmonary fibrosis), which has a prevalence of 41% to 83%. Cigarette smoke increases the expression of pulmonary ACE2 and is thought to alter susceptibility to COVID-19. Cannabis is another popular combustible product that shares some similarities with cigarette smoke, however, cannabis contains cannabinoids that may reduce inflammation and/or ACE2 levels. The role of cannabis smoke in the pathogenesis of pulmonary fibrosis remains unknown. This review aimed to characterize the ACE2-Ang-(1-7)-MasR Axis in the context of pulmonary fibrosis with an emphasis on risk factors, including the SARS-CoV-2 virus and exposure to environmental toxicants. In the context of the pandemic, there is a dire need for an understanding of pulmonary fibrotic events. More research is needed to understand the interplay between ACE2, pulmonary fibrosis, and susceptibility to coronavirus infection.
