Personal Protective Equipment Portraits Canada (PPC)-Humanization and surveying mask-wearing nationally.

Background: Personal Protective Equipment (PPE) Portraits is a hybridized art and medical intervention that lessens the alienating appearance of PPE through wearable, smiling headshot pictures. During the pandemic, the use of these portraits was expanded, but Canadian initiatives offered portraits only to immediate stakeholders. PPE Portraits Canada (PPC) aimed to provide PPE portraits to any Canadian healthcare institution and surveyed healthcare workers (HCW) regarding these portraits' impact.

Computed tomography reveals hypertrophic remodelling of the diaphragm in cystic fibrosis but not in COPD.

Background: Computed tomography (CT) is increasingly used for assessing skeletal muscle characteristics. In cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD), reduced limb muscle mass predicts poor clinical outcomes. However, the degree to which quantity or quality of respiratory and nonrespiratory muscles is affected by these diseases remains controversial.

Five ways to get a grip on organizational logistics, backends, and workflows.

Organizational backends and logistics are often complex and many institutions set-up their workflows based on manual and tedious processes that negatively shape their interactions with stakeholders. Incorporating new technologies can be intimidating. However, a plethora of financially and technically accessible resources that do not require any coding knowledge, can be utilized by institutions to enhance their organizational workflow and stakeholder experience.

The ICU Bridge Program: volunteers bridging medicine and people together.

Background: The intensive care unit (ICU) is an emotionally taxing environment. Patients and family members are at an increased risk of long-term physical and psychological consequences of critical illness, known collectively as post-intensive care syndrome (PICS). These environmental strains can lead to a high incidence of staff turnover and burnout.

Exertional dyspnoea in patients with mild-to-severe chronic obstructive pulmonary disease: neuromechanical mechanisms.

In patients with chronic obstructive pulmonary disease (COPD), exertional dyspnoea generally arises when there is imbalance between ventilatory demand and capacity, but the neurophysiological mechanisms are unclear. We therefore determined if disparity between elevated inspiratory neural drive (IND) and tidal volume (V ) responses (neuromechanical dissociation) impacted dyspnoea intensity and quality during exercise, across the COPD severity spectrum. In this two-centre, cross-sectional observational study, 89 participants with COPD divided into tertiles of FEV %predicted (Tertile 1 = FEV = 87 ± 9%, Tertile 2 = 60 ± 9%, Tertile 3 = 32 ± 8%) and 18 non-smoking controls, completed a symptom-limited cardiopulmonary exercise test (CPET) with measurement of IND by diaphragm electromyography (EMGdi (%max)).

Diaphragm Morphology Assessed by Computed Tomography in Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease (COPD) is associated with abnormal skeletal muscle morphology and function. To test the hypothesis that diaphragm muscle morphology assessed by computed tomography (CT) imaging would be associated with COPD severity, exacerbations, health status, and exercise capacity. The COPD Morphometry Study is a cross-sectional study that enrolled a clinical sample of smokers with COPD.

Physiological and perceptual responses to exercise according to locus of symptom limitation in COPD.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease, with pulmonary and extra-pulmonary factors contributing to exercise intolerance. The primary self-reported exercise-limiting symptom may reflect the primary pathophysiological factor contributing to exercise intolerance. We compared physiological and perceptual responses at the symptom-limited peak of incremental cardiopulmonary cycle exercise testing between people with COPD reporting breathlessness (B, n = 34), leg discomfort (LD, n = 16), or a combination of B and LD (BOTH, n = 42) as their main exercise-limiting symptom(s).
