Multicenter Study
Prospective study of predictive factors of changes in pain and hip function after hip fracture among the elderly.
Our study identified pre-fracture variables, such as home status or function, that are directly or indirectly associated with frailty status before fracture. The prevention in the deterioration of those variables would improve the prognosis of those hip fractured, being this an important issue for the societies with increasingly aging population. ⋯ Frailty before hip fracture is a predictor of greater post-fracture pain and deterioration in function. Given that exercise programs help prevent frailty, promoting exercise in elderly may improve the prognosis of hip fracture.

Lung strain, defined as the ratio between end-inspiratory volume and functional residual capacity, is a marker of the mechanical load during ventilation. However, changes in lung volumes in response to pressures may occur in injured lungs and modify strain values. The objective of this study was to clarify the role of recruitment in strain measurements. ⋯ Recruitment causes a shift from dynamic to static strain in early acute respiratory distress syndrome.

Randomized Controlled Trial Multicenter Study
Phase 3 solanezumab trials: Secondary outcomes in mild Alzheimer's disease patients.
EXPEDITION and EXPEDITION2 were identically designed placebo-controlled phase 3 studies assessing effects of solanezumab, an antiamyloid monoclonal antibody binding soluble amyloid-β peptide, on cognitive and functional decline over 80 weeks in patients with mild-to-moderate Alzheimer's disease (AD). Primary findings for both studies have been published. ⋯ These findings describe solanezumab effects on efficacy/safety measures in a mild AD population. Another phase 3 study, EXPEDITION3, will investigate solanezumab's effects in a mild AD population.

A subset of patients with hereditary hemorrhagic telangiectasia (HHT) develops pulmonary hypertension (PH) by mechanisms including pulmonary arterial hypertension, high flow, and elevated pulmonary arterial wedge pressure (PAWP). We aimed to describe echocardiographic and hemodynamic characteristics of patients with coexisting HHT and PH. ⋯ PH in patients with HHT occurs by different mechanisms, and there is a trend toward worse survival in patients who develop PH despite the mechanism. The equal predilection toward all subtypes of PH illustrates the necessity of RHC to clarify the hemodynamics.

Cigarette smoking is a major environmental contributor to COPD, but understanding its epigenetic regulation of oxidative genes involved in the pathogenesis of COPD remains elusive. ⋯ Cigarette smoke-induced hypermethylation of the GCLC promoter is related to the initiation and progression of COPD. Our finding may provide a new strategy for COPD intervention by developing demethylation agents targeting GCLC hypermethylation.
