Endocarditis associated with vertebral osteomyelitis and septic arthritis of the axial skeleton.

Purpose: The relationship between infective endocarditis (IE) and osteoarticular infections (OAIs) are not well known. We aimed to study the characteristics of patients with IE and OAIs, and the interactions between these two infections.

Methods: An observational study (1993-2014) which includes two cohorts: (1) patients with IE (n = 607) and (2) patients with bacteremic OAIs (n = 458; septic arthritis of peripheral and axial skeleton, and vertebral and peripheral osteomyelitis).

Clinical findings of bacteremic septic arthritis according to the site of acquisition: The overlap between health care-related and community- and nosocomial-acquired cases.

Background: The site of acquisition of infection may have a major impact on outcome. The health care-related (HCR) environment has recently come under scrutiny. In a group of patients with bacteremic septic arthritis (SA), we compared their characteristics, type of SA, microbiology and prognosis according to the site of acquisition: community-acquired (CA), nosocomial-acquired (NA), and HCR.

Lymphopenia as prognostic factor for mortality and hospital length of stay for elderly hospitalized patients.

Background: Lymphopenia is a common finding in elderly patients and its relevance is unknown.

Aims: To evaluate the clinical prognostic value of lymphopenia on the admission of elderly hospitalized patients.

Methods: From 2012 to 2013, all consecutive patients >75 hospitalized because of medical conditions were prospectively included in the study.
