Kaur H, Alluri R, Wu K, Kalayjian R, Bush W, Palella F, et al.
Antioxidants (Basel) . 2024 Sep; 13(9). PMID: 39334701
Ferroptosis is implicated in viral neuropathogenesis and may underlie HIV-associated neurocognitive impairment (NCI). Emerging data also suggest differences in brain iron transport by sex. We hypothesized that circulating ferritins that...

Luterbach C, Chen L, Komarow L, Ostrowsky B, Kaye K, Hanson B, et al.
Clin Infect Dis . 2022 Sep; 76(2):229-237. PMID: 36173830
Background: Carbapenem-resistant Klebsiella pneumoniae (CRKp) is the most prevalent carbapenem-resistant Enterobacterales in the United States. We evaluated CRKp clustering in patients in US hospitals. Methods: From April 2016 to August...

Antimicrob Agents Chemother . 2022 Sep; 66(10):e0059122. PMID: 36125299
Antimicrobial resistance is a global threat. As "proof-of-concept," we employed a system-based approach to identify patient, bacterial, and drug variables contributing to mortality in patients with carbapenem-resistant Klebsiella pneumoniae (CR)...

Auma A, Shive C, Lange A, Damjanovska S, Kowal C, Zebrowski E, et al.
Front Immunol . 2021 Apr; 12:641230. PMID: 33912168
Background: The mechanisms underlying naïve CD4+ lymphopenia during chronic Hepatitis C Virus (HCV) infection are unclear. Whether direct-acting antiviral (DAA) therapy restores peripheral naïve CD4+ T cell numbers and function...

Clin Infect Dis . 2021 Feb; 73(3):e765-e772. PMID: 33564870
Background: Neurocognitive impairment (NCI) is associated with monocyte activation in people with HIV (PWH). Activated monocytes increase glycolysis, reduce oxidative phosphorylation, and accumulate citrate and succinate, tricarboxylic acid (TCA) cycle...

Clin Infect Dis . 2019 Jun; 70(9):1826-1833. PMID: 31219148
Background: Predicting mortality risk in patients is important in research settings. The Pitt bacteremia score (PBS) is commonly used as a predictor of early mortality risk in patients with bloodstream...

J Acquir Immune Defic Syndr . 2019 Apr; 81(2):e49-e54. PMID: 30939531
Objective: To examine associations between plasma cystatin C and neurocognitive impairment (NCI) and its performance as a diagnostic marker before and during initial antiretroviral therapy (ART). Methods: Multivariable logistic regression...

In the Consortium on Resistance Against Carbapenems in and other (CRACKLE), trimethoprim-sulfamethoxazole (TMP-SMX) had a limited role in the treatment of less severe carbapenem-resistant (CRE) infections, especially urinary tract infections....

AIDS . 2018 Aug; 32(17):2517-2524. PMID: 30134291
Objective: We compared bone mineral density (BMD) changes and their correlates, between men and women participating in two randomized trials of initial [antiretroviral therapy (ART)] regimens, with or without tenofovir...
