Whether Native American ancestry (NAA) is associated with COPD or lung function in a racially admixed Hispanic population is unknown. ⋯ NAA is inversely associated with COPD but positively associated with FEV1 or FVC in Costa Ricans. Ancestral effects on smoking behavior partly explain the findings for COPD but not for FEV1 or FVC.

ABO glycosyltransferases catalyze antigen modifications on various glycans and glycoproteins and determine the ABO blood types. Blood type A has been associated with increased risk of vascular diseases and differential circulating levels of proteins related to inflammation and endothelial function. The objective of this study was to determine the association of ABO blood types with ARDS risk in patients with major trauma and severe sepsis. ⋯ Blood type A is associated with an increased risk of ARDS in white patients with major trauma and severe sepsis. These results suggest a role for ABO glycans and glycosyltransferases in ARDS susceptibility.

Review Meta Analysis
EFFECT OF CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP) ON BLOOD PRESSURE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA/HYPOPNEA. A SYSTEMATIC REVIEW AND META-ANALYSIS.
CPAP is considered the therapy of choice for OSA, but the extent to which it can reduce BP is still under debate. We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to quantify the effect size of the reduction of BP by CPAP therapy compared with other passive (sham CPAP, tablets of placebo drug, conservative measures) or active (oral appliance, antihypertensive drugs) treatments. ⋯ Therapy with CPAP significantly reduces BP in patients with OSA but with a low effect size. Patients with frequent apneic episodes may benefit the most from CPAP.
