Chronic Obstructive #Pulmonary Disease and Incidence of #Hip Fracture: A Nested Case–Control Study in the EpiChron Cohort

To determine whether chronic obstructive pulmonary disease (COPD) is a risk factor for hip fracture and identify other factors associated with hip fracture. Patients and Methods: Observational nested case–control study was conducted in Aragon, Spain in 2010. We included COPD patients aged > 40 years, in the EpiChron cohort. Each COPD patient was matched for age, sex, and number of comorbidities with a control subject … Continue reading Chronic Obstructive #Pulmonary Disease and Incidence of #Hip Fracture: A Nested Case–Control Study in the EpiChron Cohort

Quick #COVID-19 Healers Sustain Anti-SARS-CoV-2 #Antibody Production

Antibodies are key immune effectors that confer protection against pathogenic threats. The nature and longevity of the antibody response to SARS-CoV-2 infection is not well defined. We charted longitudinal antibody responses to SARS-CoV-2 in 92 subjects after symptomatic COVID-19. Antibody responses to SARS-CoV-2 are unimodally distributed over a broad range, with symptom severity correlating directly with virus-specific antibody magnitude. Seventy-six subjects followed longitudinally to ∼100 … Continue reading Quick #COVID-19 Healers Sustain Anti-SARS-CoV-2 #Antibody Production
