Recipient sepsis caused by Lactococcus garvieae contamination of platelets from a donor with colon cancer.

Lactococcus garvieae is a well-known fish pathogen that has low virulence in humans and is rarely isolated from the blood cultures of endocarditis patients. We describe herein the first reported case of transfusion-transmitted L. garvieae sepsis caused by a contaminated platelet concentrate from a donor who consumed raw octopus before blood donation.

Coexisting COPD in elderly asthma with fixed airflow limitation: Assessment by DLco %predicted and HRCT.

Background: Asthma patients with fixed airflow limitation (FL) are theoretically classified into two phenotypes, that is, coexisting chronic obstructive pulmonary disease (COPD) and asthmatic airway remodeling. However, the precise percentages of such patients are not known.

Objective: To assess the prevalence of patients with both FL and COPD components in elderly asthma.

Biomarker-based detection of asthma-COPD overlap syndrome in COPD populations.

Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) was proposed by the science committees of both Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD). However, the definition of ACOS has remained unclear all over the world, and the prevalence rate of ACOS is basically dependent on the patient's symptoms or the physician's opinion, based on questionnaire testing. In the current case report, we investigated the prevalence rate of COPD patients with high levels of fractional exhaled nitric oxide (FENO) or immunoglobulin E (IgE) as candidate markers of ACOS in COPD, as a multicenter, cross-sectional study.
