Mechanisms, Pathophysiology, and Management of Obesity

Obesity is prevalent in the U.S. population and contributes significantly to morbidity and mortality. Treatments include behavioral therapy, pharmacotherapy, and bariatric surgery. Some sequelae of obesity are reversed with weight loss. Maintaining weight loss is a challenge.

ORIGINAL ARTICLE

Ocrelizumab versus Placebo in Primary Progressive Multiple Sclerosis


Patients with primary progressive MS who received the anti-CD20+ humanized antibody ocrelizumab were less likely to have clinical deterioration that was sustained for 12 weeks than those who received placebo. The drug was associated with decreased lesion activity on MRI.


ORIGINAL ARTICLE

Ocrelizumab versus Interferon Beta-1a in Relapsing Multiple Sclerosis


In two trials involving patients with relapsing multiple sclerosis, the anti-CD20+ monoclonal antibody ocrelizumab was associated with lower annualized relapse rates, lower risk of disability progression, and better MRI features than interferon beta-1a.

Resolution of Disease Phenotypes Resulting from Multilocus Genomic Variation


Of over 7000 patients referred to a diagnostic laboratory, 28% had diagnoses based on DNA sequencing, 5% of whom had two or more diagnoses. Their phenotypes could be better understood by considering whether the implicated genes affect independent biologic processes or organ systems.

Ticagrelor versus Clopidogrel in Symptomatic Peripheral Artery Disease


In this randomized trial involving 13,885 patients with symptomatic peripheral artery disease (PAD), ticagrelor was not shown to be superior to clopidogrel for the reduction of cardiovascular events. Major bleeding occurred at similar rates with ticagrelor and clopidogrel.
