Objective Eighteen million Americans with type 2 diabetes (T2D) do not follow recommended guidelines for physical activity. Motivational interviewing (MI) has had modest effects on activity and related behaviors in T2D. Positive psychological attributes (e.g., optimism) are associated with superior medical outcomes in T2D, and positive psychology (PP) interventions promote such attributes. There had been no study in T2D of a combined PP-MI intervention to promote well-being and health behavior adherence. We developed a novel, telephone-delivered, 16-week PP-MI intervention and explored its feasibility and impact in T2D patients in a single-arm, proof-of-concept trial...

Disease severity of sickle cell anemia is highly variable, and it is commonly accepted that fetal hemoglobin (HbF) levels play a major role as an ameliorating factor. Investigation of genetic variants have identified several genes to be the principal influencers of HbF regulation. Here, we further elucidated the association of rs4527238 and rs35685045 of ANTXR1 genes in the context of HbF level variance in sickle cell anemia patients of the Arab-Indian haplotype. Samples from 630 sickle cell anemia patients were analyzed for the mutations at 2 specific locations of the ANTXR1 gene by TaqMan®-based real-time PCR...

Preoperative anemia occurs in about one third of patients who undergo elective surgery and is associated with an impaired outcome. Therefore, screening of preoperative anemia was established in the context of a multidisciplinary Patient Blood Management (PBM) program at the University Hospital of Muenster, Germany. Anemic patients without contraindications were treated with intravenous (IV) iron (ferric carboxymaltose) to increase their hemoglobin (Hgb) levels and hence to treat anemia prior to surgery. Interestingly, we detected a large variability in the response of Hgb levels after IV iron administration...

Introduction: The Framingham Studies revealed that diabetes mellitus (DM) predisposed subjects to a two- to eight-fold increase in the risk of developing heart failure (HF). However, there is much less information available about the reverse issue; namely, whether there is an increased risk of developing DM in patients with HF. We sought to determine if reversal or partial reversal of HF through aortic valve replacement (AVR) would improve glycemic control in patients with DM at our institution...
