BACKGROUND To assess the symptomatic and cost burden among patients initiating long-acting bronchodilator (LABD) therapy and impact of adherence on healthcare resource use and costs. METHODS This retrospective cohort study identified patients with COPD who were newly prescribed a LABD (long-acting muscarinic antagonist [LAMA], long-acting beta2-agonist [LABA], a combination of LABA+LAMA or co...

BACKGROUND The nonvitamin K antagonist oral anticoagulants have recently become available as an alternative to warfarin as stroke prophylaxis in atrial fibrillation, but data on real-life patient experience, including bleeding risk, are lacking. Our objective was to compare major bleeding events and nonpersistence between the nonvitamin K antagonist oral anticoagulant apixaban and other nonvita...

BACKGROUND Hyperuricemia and gout are associated with an increased risk of cardiovascular disease (CVD). It is unknown whether treating hyperuricemia with xanthine oxidase inhibitors (XOIs), including allopurinol and febuxostat, modifies cardiovascular risks. METHODS We used US insurance claims data to conduct a cohort study among gout patients, comparing XOI initiators with non-users with hy...

In a longitudinal dataset of 470 Dutch adolescents, the current study examined the ways in which early sexual initiation was related to subsequent attachment, self-perception, internalizing problems, and externalizing problems. For male adolescents, analyses revealed general attachment to mother and externalizing problems at Wave 1 to predict to early transition at Wave 2. However, there was no...

Quantum-chemical calculations and in vitro experiments have demonstrated that polysaccharides are able to adsorb mononucleotides due to the formation of hydrogen bonds. The subsequent dehydration of polysaccharide-nucleotide complexes in the physiologically acceptable temperature range results in the creation of “correct” DNA polymers that are “recognized” by the specific DNA-polymerases. DNA f...

The concept of anionic polymerization was first developed by Ziegler and Schlenk in early 1910. Their pioneering work on the polymerization of diene initiated with sodium metal set the stage for the use of alkali metal containing aromatic hydrocarbon complexes as initiators for various α-olefins. In 1939, Scott and coworkers used for the first time the alkali metal complexes of aromatic hydroca...
