Women globally need access to multipurpose prevention technologies (MPTs) that prevent human immunodeficiency virus (HIV), sexually transmitted infections that increase HIV acquisition/transmission risk, and unintended pregnancy. Seeking an MPTwith activity against HIV, herpes simplex virus-2 (HSV-2), and human papillomavirus (HPV), we developed a prototype intravaginal ring (IVR), the MZCL IVR, which released the antiviral agents MIV-150, zinc acetate, and carrageenan (MZC for short) and the contraceptive levonorgestrel (LNG). Previously, we showed that an MZC gel has potent activity against immunodeficiency viruses, HSV-2, and HPVand that the MZCL (MZC with LNG) IVR releases all four components in macaques in vivo at …

We assessed predictors of choosing self-administered oral HIV testing in the clinic with supervision versus the standard provider-administered blood test when offered the choice among 149 Kenyan truck drivers, described the types of guidance participants needed during self-testing and predictors of needing guidance. Overall, 56.38% of participants chose the self-test, 23.49% the provider-administered test, and 20.13% refused testing. In the adjusted regression models, each additional unit on the fatalism and self-efficacy scales was associated with 0.97 (p = 0.003) and 0.83 (p = 0.008) times lower odds of choosing the self-test, respectively. Overall, 52.38% of self-testers did so correctly without …

Sensory neuropathies are the most common neurological complication of HIV. Of these, distal sensory polyneuropathy (DSP) is directly caused by HIV infection and characterized by length-dependent axonal degeneration of dorsal root ganglion (DRG) neurons. Mechanisms for axonal degeneration in DSP remain unclear, but recent experiments revealed that the HIV glycoprotein gp120 is internalized and localized within axons of DRG neurons. Based on these findings, we investigated whether intra-axonal gp120 might impair fast axonal transport (FAT), a cellular process critical for appropriate maintenance of the axonal compartment. Significantly, we found that gp120 severely impaired both anterograde and retrograde FAT. Providing a …
