ABT-072 is a non-nucleoside HCV NS5B polymerase inhibitor that was discovered as part of a program to identify new direct-acting antivirals (DAAs) for the treatment of HCV infection. This compound was identified during a medicinal chemistry effort to improve on an original lead, inhibitor 1, which we described in a previous publication. Replacement of the amide linkage in 1 with a trans-olefin resulted in improved compound permeability and solubility, and provided much better pharmacokinetic properties in preclinical species...

Iodine is an essential micronutrient required for normal growth and neurodevelopment; thus, an adequate intake of iodine is particularly important for pregnant and lactating women, and throughout childhood. Low levels of iodine in the soil and groundwater are common in many parts of the world, often leading to diets that are low in iodine. Widespread salt iodization has eradicated severe iodine deficiency, but mild-to-moderate deficiency is still prevalent even in many developed countries. To understand patterns of iodine intake and to develop strategies for improving intake, it is important to characterize all sources of dietary iodine, and national databases on the iodine content of major dietary contributors (including foods, beverages, water, salts, and supplements) provide a key information resource...

BACKGROUND: The rate of cardiovascular implantable electronic device infection (CIEDI) has increased, despite the use of perioperative antibiotics at the time of device placement or revision. This is due, in part, to the presence of multiple comorbid conditions in an elderly population, in general, who require CIED. Statins may have an antibacterial effect, although there is currently no evidence that the likelihood of CIEDI has been impacted by statin use. METHODS: A retrospective cohort study was performed to assess whether statins are associated with a reduced risk of CIEDI...

Extramedullary plasmacytoma as a mode of relapse in multiple myeloma (MM) is unusual. Current recommendations do not incorporate the routine use of 18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) imaging prior to haematopoietic stem cell transplant (HSCT) in MM. We report a case of relapsed MM with complete remission as per IMWG criteria. In the interim period, before the HSCT, the patient had localizing neurological signs and symptoms attributed to multiple extramedullary plasmacytomas...

The olive fruit fly, Bactrocera oleae, is the single most important pest for the majority of olive plantations. Oxitec's self-limiting olive fly technology (OX3097D-Bol) offers an alternative management approach to this insect pest. Because of previously reported asynchrony in the mating time of wild and laboratory strains, we have characterized the olive fly circadian clock applying molecular, evolutionary, anatomical and behavioural approaches. Here we demonstrate that the olive fly clock relies on a Drosophila melanogaster-like organization and that OX3097D-Bol carries a functional clock similar to wild-type strains, confirming its suitability for operational use...

Although the introduction of antiretroviral therapy has rendered HIV a chronic illness, inconsistent engagement in HIV care by key populations limits its public health impact. Poor engagement in care is especially prevalent among vulnerable populations with mental health and substance use disorders. Beyond structural and health system considerations, psychosocial factors may present challenges to sustained engagement. We conducted a qualitative study using in-depth interviews with 31 primarily African American, urban-based individuals, many with past or current drug use and mental disorders, living with HIV...

Purines are metabolic building blocks essential for all living organisms on earth. De novo purine biosynthesis occurs in the brain and appears to play important roles in neural development. Phosphoribosyl formylglycinamidine synthase (FGAMS, also known as PFAS or FGARAT), a core enzyme involved in the de novo synthesis of purines, may play alternative roles in viral pathogenesis. To date, no thorough investigation of the endogenous expression and localization of de novo purine biosynthetic enzymes has been conducted in human neurons or in virally infected cells...

Tertiary hospitals are increasingly called on by smaller hospitals and free-standing emergency rooms (ERs) to provide surgical care for complex patients. This study assesses patients transferred to an acute care surgery service. The ER and transfer center logs, as well as billing data, were reviewed for 12 months for all cases evaluated by acute care surgery. The charts were reviewed for demographics, comorbidities, and outcomes. A total of 111 transferred patients with complete data were identified, with 59 transferred from another hospital and 52 from a free-standing ER...

Highly efficient and stable electrocatalysts, particularly those that are capable of multifunctionality in the same electrolyte, are in high demand for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). In this work, highly monodisperse CoP and Co2 P nanocrystals (NCs) are synthesized using a robust solution-phase method. The highly exposed (211) crystal plane and abundant surface phosphide atoms make the CoP NCs efficient catalysts toward ORR and HER, while metal-rich Co2 P NCs show higher OER performance owing to easier formation of plentiful Co2 P@COOH heterojunctions...

The pediatric rheumatic diseases are a heterogeneous group of rare diseases, posing a number of challenges for the use of traditional clinical and translational research approaches. Innovative comparative effectiveness approaches are needed to efficiently study treatment approaches and disease outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed the consensus treatment plan (CTP) approach as a comparative effectiveness tool for research in pediatric rheumatology. CTPs are treatment strategies, developed by consensus methods among CARRA members, intended to reduce variation in treatment approaches, standardize outcome measurements, and allow for comparison of the effectiveness of different approaches with the goal of improving disease outcomes...

Ensuring adequate vascular access in major trauma patients prior to decompensative physiological processes is crucial to patient outcomes. Most protocols suggest achieving two 18-gauge or larger intravenous lines immediately in patients with major trauma. We discuss a quality improvement approach to ensure that >90% of patients with major trauma (as defined by an injury severity score ≥12) at a level one trauma centre receive timely and adequate fluid access. Applying Donabedian principles for process improvement, we used the Alberta Trauma Registry to perform a 4-month chart audit on patients with major trauma at the University of Alberta Hospital...
