Perceptions of Long-Acting Injectable Antiretroviral Therapy Among People Living with HIV Who Use Drugs and Service Providers: a Qualitative Analysis in Rhode Island.

Long-acting injectable antiretroviral therapy (LAI-ART) is a novel method to deliver HIV treatment, and the first regimen was approved in the USA in 2021. LAI-ART may mitigate barriers to oral treatment adherence, but little is known about LAI-ART perceptions among people living with HIV (PLWH) who use drugs, despite these populations facing greater barriers to treatment retention and ART adherence. We assessed LAI-ART perceptions and implementation considerations among PLWH who use drugs and health and ancillary service providers in Rhode Island. Data was collected from November 2021 to September 2022, and include in-depth interviews with 15 PLWH who use drugs and two focus groups with HIV clinical providers (n = 8) and ancillary service providers (n = 5) working with PLWH who use drugs. Data were analyzed thematically, with attention paid to how levels of structural vulnerability and social-structural environments shaped participants' LAI-ART perceptions and the HIV care continuum. Willingness to consider LAI-ART was impacted by HIV outcomes (e.g., viral suppression) and previous experiences with oral regimens, with those on stable regimens reluctant to consider alternative therapies. However, LAI-ART was seen as potentially improving HIV outcomes for PLWH who use drugs and enhancing people's quality of life by reducing stress related to daily pill-taking. Recommendations for optimal implementation of LAI-ART varied across participants and included decentralized approaches to delivery. HIV care delivery must consider the needs of PLWH who use drugs. Developing patient-centered and community-based delivery approaches to LAI-ART may address adherence challenges specific to PLWH who use drugs.

Pasteurella Multocida Urinary Tract Infection in a Susceptible Patient with Non-Traumatic Feline Contact.

Pasteurella multocida is a part of the normal oral flora of domestic animals. Humans can develop skin and soft tissue infections from P. multocida after traumatic animal contact, usually through bites and scratches from domestic animals. Although rare, there have been documented case reports where P. multocida has been isolated from patients even after minimal casual animal contact. Even rarer, is the isolation of P. multocida from urine. The few documented cases of urine isolation have been described in patients who have underlying medical conditions, particularly those with urologic abnormalities. Here we present a 34-year-old female patient with known congenital neurological and urological anomalies who developed a P. multocida urinary tract infection from casual contact with a household feline, a previously unrecognized risk factor for P. multocida UTI in anatomically susceptible individuals.

Cerebral fat embolism syndrome in sickle cell disease without evidence of shunt.

Fat embolism syndrome (FES) is a known complication of sickle cell disease (SCD) that occurs secondary to vaso-occlusive crises, bone marrow infarction, and the subsequent release of fat globules into the venous circulation. Although neurologic involvement is common, the pathophysiology of cerebral fat emboli remains controversial. While fat microemboli can enter the arterial circulation through right-to-left shunts, the systemic release of free fatty acids may also cause indirect endothelial damage and disruption of the blood-brain-barrier. We present an unusual case of cerebral fat emboli in SCD that occurred in the absence of acute chest syndrome or right-to-left shunt, favoring a biochemical etiology. Treatment of FES includes supportive care and emergent red cell exchange transfusions.
