Newest firstObjectivesAsthma exacerbations pose substantial risk to adolescents. We evaluated whether documented nicotine use, cannabis use, or concurrent use is associated with increased emergency department (ED) management intensity and adverse short-term outcomes during asthma exacerbations.MethodsUsing the TriNetX database, we identified adolescents aged 11 to 21 years presenting to the ED with an acute asthma exacerbatio…
Open article record in new tab ↗Background Cannabis may cause chronic pulmonary disease. Prior studies have been limited by low cannabis exposure, lack of data on tobacco cigarettes, and/or limited numbers of those without tobacco cigarette use. Objective To examine whether inhaled cannabis associated with asthma and chronic obstructive pulmonary disease, independent of tobacco cigarettes. Design Cross-sectional analysis of population-based, nat…
BackgroundSalbutamol is the most commonly prescribed inhaler for adults discharged from the Emergency Department (ED) with uncontrolled asthma. However newer options, e.g. Maintenance and Reliever Therapy (MART), are now recommended due to growing concerns over risks linked to salbutamol over-prescription. Transitioning to new inhalers requires support for both patients and healthcare professionals (HCP). This pap…
The beneficial effects of cannabinoids in the treatment of respiratory diseases have been drawing researchers' attention for several decades. Asthma is a complex disease entity characterized by a variable course, the treatment of which requires the continuous search for alternative, adjuvant treatment strategies designed for patients refractory to available pharmacotherapies. Cannabinoids exert certain physiologic…
A 23-year-old man presented with a life-threatening asthma exacerbation following a respiratory infection. Although he had a childhood history of asthma, he had remained asymptomatic in adulthood and reported regular use of both vapes and marijuana. His medical history included Type 2 Loeys-Dietz syndrome (LDS), requiring multiple vascular surgeries, rendering standard asthma therapies relatively contraindicated.…
Open article record in new tab ↗BackgroundAsthma is frequently misdiagnosed because clinic-based tests miss its natural variability. As part of early stakeholder engagement, we examined primary-care healthcare professionals (HCP) views on using handheld spirometer and fractional exhaled nitric oxide (FeNO) devices for home-based diagnostic strategies. MethodsThis mixed-method study was conducted in two phases. Phase 1 data collection involved tw…
Open article record in new tab ↗ObjectiveTo quantify, compare, and analyse the cradle-to-gate carbon emissions of biologic treatments for severe asthma. DesignCradle-to-gate carbon emissions for six monoclonal antibody therapies were calculated using MCF Classifier. A representative patient, eligible for all therapies, was defined to enable comparisons. Sensitivity, scenario, and pairwise analyses were conducted to explore variation in emissions…
Open article record in new tab ↗Background and objectives Secondhand tobacco smoke is associated with worsening asthma symptoms among children. However, the relationship between secondhand marijuana smoke and asthma symptoms among youth has not been examined. This study compares the prevalence of secondhand tobacco and marijuana smoke exposure, overall and by asthma status, among middle and high school students. Methods The study assessed partic…
Open article record in new tab ↗OBJECTIVES: Respiratory diseases are the leading cause of hospitalization in Nunavik (northern Québec, Canada) and contribute to disparities in life expectancy with the rest of Canada. As part of Qanuilirpitaa? 2017, a cross-sectional population-based health survey, we sought to describe the prevalence of respiratory health indicators, including the first estimate of airway obstruction based on spirometry in an In…
Anaphylaxis is a life-threatening reaction characterized by the acute onset of symptoms involving different organ systems and requiring immediate medical intervention. The incidence of fatal food anaphylaxis is 0.03 to 0.3 million/people/year. Most fatal food-induced anaphylaxis occurs in the second and third decades of life. The identified risk factors include the delayed use of epinephrine, the presence of asthm…
Open article record in new tab ↗The cannabinoid CB2 receptor was cloned from the promyeloid cell line HL-60 and is notably expressed in most, if not all leukocyte types. This relatively restricted localization, combined to the absence of psychotropic effects following its activation, make it an attractive drug target for inflammatory and autoimmune diseases. Therefore, there has been an increasing interest in the past decades to identify precise…
Open article record in new tab ↗Chronic obstructive airway diseases are a global medical burden that is expected to increase in the near future. However, the underlying mechanistic processes are poorly understood so far. Herein, we show that the endocannabinoid anandamide (AEA) induces prominent airway relaxation in vitro and in vivo. In contrast to 2-arachidonlyglycerol-induced airway relaxation, this is mediated by fatty acid amide hydrolase (…
Open article record in new tab ↗High eosinophil (EOS) counts are a key feature of eosinophilic asthma. EOS notably affect asthmatic response by generating several lipid mediators. Mice have been utilized in hopes of defining new pharmacological targets to treat asthma. However, many pinpointed targets in mice did not translate into clinics, underscoring that key differences exist between the two species. In this study, we compared the ability of…
Non-steroidal anti-inflammatory drugs (NSAIDs) and other eicosanoid pathway modifiers are among the most ubiquitously used medications in the general population. Their broad anti-inflammatory, antipyretic, and analgesic effects are applied against symptoms of respiratory infections, including SARS-CoV-2, as well as in other acute and chronic inflammatory diseases that often coexist with allergy and asthma. However…
Introduction Recent studies have raised the concern on the risk of asthma in marijuana smokers; however, the results remain controversial and warrant further investigation. With a growing number of marijuana smokers, examining the association between marijuana smoking and asthma and quantifying such association through meta-analysis have important implications for public health and clinical decision-making. In vie…
Open article record in new tab ↗Electronic health records (EHRs) provide a rich source of observational patient data that can be explored to infer underlying causal relationships. These causal relationships can be applied to augment medical decision-making or suggest hypotheses for healthcare research. In this study, we explored a large-scale EHR dataset on patients with asthma or related conditions (N = 14,937). The dataset included integrated…
Open article record in new tab ↗Cannabis use is growing, with multiple medical 'indications' and approval for recreational use in many countries. This article will review some of the respiratory complications to cannabis use, which include lung function changes, lung destruction, increased risk of lung and head and neck cancer, and others. These are mostly related to smoking, and the co-administration of nicotine makes the risks a bit difficult…
Open article record in new tab ↗Asthma is a chronic eosinophilic inflammatory disease with an increasing prevalence worldwide. Endocannabinoids are known to have immunomodulatory biological effects. However, the contribution of oleoylethanolamide (OEA) to airway inflammation remains to be elucidated. To investigate the effect of OEA, the expression of proinflammatory cytokines was measured by RT-qPCR and ELISA in airway epithelial (A549) cells.…
