Lung clearance index: A sensitive measure of airway function improvement in adolescents after weight loss from bariatric surgery.

Background: Morbid obesity in adolescents impacts respiratory function, often leading to reduced lung volume and obstructive ventilatory defects. However, standard spirometric values frequently remain within normal ranges.

Objectives: We hypothesized that Lung Clearance Index (LCI) is a more sensitive marker for detecting airway dysfunction in adolescents with morbid obesity than conventional lung function tests.

Clinical implications of reconsideration of enthesitis/enthesopathy/enthesial erosion, as tendon attachment-localized avulsions and stress fracture equivalents.

Recognizing the mechanical origin of enthesitis/enthesopathy and the avulsion-nature of what had previously been considered erosions, it seems inappropriate to attribute it to stresses related to a person's normal activities. Conversely, sudden or unconditioned repetitive stresses appears the more likely culprit. Studies of enthesial reaction have lacked standardization as to findings present among individuals who appear to be healthy.

Entheseal surface (Sharpey's fiber insertion) alterations identify past trauma; bone base robusticity, level of routine activity.

Sharpey's fiber alterations, referred to as entheseal reaction or enthesopathy, have long been considered an indicator of daily activities. Such semantic transformation seems to conflate processes which alter the characteristics of tendonous and ligamentous attachments to bone with the rugosity and extent of their base/footprint. Rather than reflecting normal activities, it is suggested that surface reactions are actually the response to the application of sudden or unconditioned repetitive stresses-analogous to stress fractures.

Wearing face masks while climbing stairs influences respiratory physiology.

During the COVID-19 pandemic wearing face masks was mandatory. Nowadays, face masks are still encouraged indoors, especially in hospitals. People climbing stairs with masks describe unpredictable dyspnea.

Pulmonary Evaluation in Children with Post-COVID-19 Condition Respiratory Symptoms: A Prospective Cohort Study.

Studies on post-COVID-19 condition (PCC) in adults have shown deterioration in pulmonary function tests (PFTs), mainly a diffusion limitation. Among the pediatric population, data are scarce. To characterize PFTs in children with PCC, including changes over time.
