Challenges recruiting and retaining people at risk for HIV who use methamphetamine in a randomized PrEP adherence trial in Seattle, WA.

Background: Methamphetamine is associated with increased HIV risk and suboptimal adherence to pre-exposure prophylaxis (PrEP). Interventions to support PrEP adherence for people who use methamphetamine are needed.

Methods: We evaluated peer navigation to support adherence among people initiating PrEP who use methamphetamine.

Barriers and facilitators to implementing a Pharmacist, Physician, and Patient Navigator-Collaborative Care Model (PPP-CCM) to treat hepatitis C among people who inject drugs.

Background: Direct-acting antivirals (DAAs) offer an unprecedented opportunity to eliminate hepatitis C virus (HCV) infection, yet barriers among people who inject drugs (PWID) remain. Having pharmacists provide care through collaborative drug therapy agreements (CDTAs) offers a promising solution. We developed and piloted a Pharmacist, Physician, and Patient Navigator-Collaborative Care Model (PPP-CCM) which utilized pharmacists to directly deliver HCV care at community organizations serving PWID.

Health care-seeking experiences for people who inject drugs with hepatitis C: Qualitative explorations of stigma.

Introduction: People who inject drugs (PWID) have complex health needs and often experience poor health outcomes. For PWID, intersectional experiences of stigma and other social vulnerabilities may influence their experiences navigating medical care. We conducted a targeted subanalysis of qualitative interview data collected to inform development of a community-pharmacist care model for hepatitis C (HCV) among PWID to explore intersectional influences on health care-seeking experiences.

'Treat my whole person, not just my condition': qualitative explorations of hepatitis C care delivery preferences among people who inject drugs.

Background: The advent of direct-acting antivirals (DAAs)-a form of hepatitis C (HCV) treatment associated with shorter treatment course and greater efficacy-offers an unprecedented opportunity to eliminate HCV, but only if care delivery systems are developed to extend treatment to people who inject drugs (PWID). To support the design of a community-pharmacy program, we explored perspectives of PWID with chronic HCV with regard to barriers, motivators, preferences, and prior experiences related to HCV treatment and pharmacists.

Methods: We conducted semi-structured interviews with people living with HCV who reported active injection drug use.

Patient-Focused Selection of PrEP Medication for Individuals at Risk of HIV: A Narrative Review.

Pre-exposure prophylaxis (PrEP) medication is a key component of the HIV prevention strategy in the US, which has been demonstrated to be highly effective in preventing HIV acquisition among individuals at risk. Two PrEP medications are currently approved: emtricitabine/tenofovir disoproxil fumarate (Truvada; F/TDF) was approved by the US Food and Drug Administration in 2012, followed by emtricitabine/tenofovir alafenamide (Descovy; F/TAF) in 2019. An ongoing randomized, double-blind, Phase 3 study (DISCOVER) demonstrated that F/TAF had non-inferior efficacy to F/TDF.

The Role of Pharmacies in the HIV Prevention and Care Continuums: A Systematic Review.

The role of pharmacists in the treatment of HIV has expanded beyond medication dispensing to include a host of cost-effective, evidence-based strategies across the HIV prevention and care continuums. However, wide-scale adoption of pharmacy-based HIV prevention and treatment interventions has been slow. We conducted a systematic review to evaluate the evidence on the role of pharmacists across the HIV prevention and care continuums.

Implementation of a community pharmacy-based pre-exposure prophylaxis service: a novel model for pre-exposure prophylaxis care.

Unlabelled: Background National guidelines for the provision of HIV pre-exposure prophylaxis (PrEP) to reduce a person's risk of acquiring HIV were made available in 2014. We created a pharmacist-managed HIV PrEP clinic in a community pharmacy setting at Kelley-Ross Pharmacy in Seattle, WA, USA.

Methods: The clinic operates under a collaborative drug therapy agreement based on these guidelines.

Role of carbonic anhydrase II in ectopic calcification.

Introduction: Osteopontin (OPN) is a potent inhibitor of ectopic calcification. Previous studies suggested that, in addition to blocking apatite crystal growth, OPN promoted regression of ectopic calcification by inducing the expression of acid-generating carbonic anhydrase II (CAR2) in monocyte-derived cells.

Methods: To test this hypothesis, OPN and CAR2 expression and calcification of subcutaneously implanted glutaraldehyde-fixed bovine pericardium (GFBP) were studied in CAR2 mutant mice.

Mitigation of ectopic calcification in osteopontin-deficient mice by exogenous osteopontin.

Ectopic calcification is a major cause of bioprosthetic heart valve failure. New therapeutic opportunities are offered by the growing understanding that ectopic calcification is an actively regulated process involving several key gene products. One of these products, osteopontin (OPN), is a glycosylated phosphoprotein previously shown to inhibit apatite crystal formation, induce carbonic anhydrase II, and promote mineral resorption.

Inactivation of the osteopontin gene enhances vascular calcification of matrix Gla protein-deficient mice: evidence for osteopontin as an inducible inhibitor of vascular calcification in vivo.

Osteopontin (OPN) is abundantly expressed in human calcified arteries. To examine the role of OPN in vascular calcification, OPN mutant mice were crossed with matrix Gla protein (MGP) mutant mice. Mice deficient in MGP alone (MGP(-/-) OPN(+/+)) showed calcification of their arteries as early as 2 weeks (wk) after birth (0.
