Diabetes Microvascular Complications Are Associated with a Reduction in Gait Speed in High-Functioning Older Adults for Outpatient Clinics.

Although the association of type 2 diabetes (T2D) with an increased risk of poor physical function and frailty in older adults is widely documented, the underlying pathophysiological pathways linking these two entities are not fully understood. Accordingly, we conducted a cross-sectional observational study aiming to investigate the association of T2D and its microvascular complications retinopathy, nephropathy, and neuropathy, with gait speed (GS), a common surrogate marker of functional decline, adjusting for age, sex, and cognitive function, in the cohort of older adults of the DIALCAT project (Catalonia, Spain). From the initial 335 participants, 84 were excluded because of missing or incorrect GS assessment.

Dual-task related frontal cerebral blood flow changes in older adults with mild cognitive impairment: A functional diffuse correlation spectroscopy study.

Introduction: In a worldwide aging population with a high prevalence of motor and cognitive impairment, it is paramount to improve knowledge about underlying mechanisms of motor and cognitive function and their interplay in the aging processes.

Methods: We measured prefrontal cerebral blood flow (CBF) using functional diffuse correlation spectroscopy during motor and dual-task. We aimed to compare CBF changes among 49 older adults with and without mild cognitive impairment (MCI) during a dual-task paradigm (normal walk, 2- forward count walk, 3-backward count walk, obstacle negotiation, and heel tapping).

Cluster-derived obstructive sleep apnea phenotypes and outcomes at 5-year follow-up.

Study Objectives: Obstructive sleep apnea (OSA) is a heterogeneous, complex disease. We aimed to identify OSA phenotypes through cluster analysis and to perform a long-term follow-up to validate the phenotypes.

Methods: We applied a partitioning around medioids technique in a cohort of 1,217 participants recently diagnosed with OSA.

Serological evolution in early syphilis.

Introduction: The evolution of syphilis after treatment could be affected by different factors, for example HIV. In consequence, HIV positive patients are sometimes treated with more doses of penicillin (PBG). The aim of the study is to describe and compare the serological evolution by different factors in patients with early syphilis in Barcelona.
