Statin use for cardiovascular disease prevention: perceptions among people living with HIV in the United States.

Background: People living with HIV (PLWH) may be at heightened risk for cardiovascular disease (CVD). Statin use and lifestyle changes reduce the risk of CVD but remain under-prescribed among PLWH. The objective of this study was to characterize knowledge of CVD and statin use, current usage, barriers to taking statins, and information desired by PLWH to improve statin uptake among PLWH in Los Angeles, CA.

Implementation, Maintenance, and Outcomes of an Electronic Referral to a Tobacco Quitline Across Five Health Systems.

Introduction: Electronic referral (e-referral) to quitlines helps connect tobacco-using patients to free, evidence-based cessation counseling. Little has been published about the real-world implementation of e-referrals across U.S.

Under the radar: co-introduced monogeneans (Polyopisthocotylea: Gastrocotylinea) of the invasive fish Scomberomorus commerson in the Mediterranean Sea.

The Levant Basin is in many ways the world's most invaded marine ecosystem owing to the existence of the man-made Suez Canal. The invasion of free-living organisms through this pathway is increasingly documented and monitored in the past two decades, and their ecological impact recognized. Nonetheless, while tremendous scientific effort is invested in documenting introduced fishes, co-introduction events of these fishes and their parasites have drawn relatively little interest.

Dynamic multistage scheduling for patient-centered care plans.

We investigate the scheduling practices of multistage outpatient health programs that offer care plans customized to the needs of their patients. We formulate the scheduling problem as a Markov decision process (MDP) where patients can reschedule their appointment, may fail to show up, and may become ineligible. The MDP has an exponentially large state space and thus, we introduce a linear approximation to the value function.
