Extracellular vesicles produced by HIV-1 Nef-expressing cells induce myelin impairment and oligodendrocyte damage in the mouse central nervous system.

HIV-associated neurocognitive disorders (HAND) are a spectrum of cognitive impairments that continue to affect approximately half of all HIV-positive individuals despite effective viral suppression through antiretroviral therapy (ART). White matter pathologies have persisted in the ART era, and the degree of white matter damage correlates with the degree of neurocognitive impairment in patients with HAND. The HIV protein Nef has been implicated in HAND pathogenesis, but its effect on white matter damage has not been well characterized.

Transcervical microwave ablation in type 2 uterine fibroids via a hysteroscopic approach: analysis of ablation profiles.

Type 2 uterine fibroids are challenging to resect surgically as ≥ 50% volume of myoma lies within the myometrium. A hysteroscopic approach for ablating fibroids is minimally-invasive, but places a considerable burden on the operator to accurately place the ablation applicator within the target. We investigated the sensitivity of transcervical microwave ablation outcome with respect to position of the ablation applicator within 1 - 3 cm type 2 fibroids.

Brief Report: Adiponectin Levels Linked to Subclinical Myocardial Fibrosis in HIV.

Background: Persons living with HIV (PLWH) are at an increased risk of myocardial dysfunction and metabolic disturbances represent one of several potential contributing factors. Adiponectin is an adipokine that enhances insulin sensitivity with potential cardioprotective effects. We therefore investigated the relationship between myocardial fibrosis, adiponectin, and related metabolic parameters to better understand the pathophysiologic mechanisms of myocardial injury in PLWH.
