Age-Independent Anti-Angiogenic Therapy For Choroidal Neovascularization By Targeting Secretogranin Iii, Chengchi Huang, Hong Tian, Wei Li

Faculty, Staff and Students Publications

Recent studies reported that anti-angiogenic drugs targeting vascular endothelial growth factor (VEGF) alleviate choroidal neovascularization (CNV) in young but not aged animals. We recently developed a disease-targeted anti-angiogenic therapy against secretogranin III (Scg3), which selectively binds to diseased but not healthy vessels in young mice. Herein, using a unique in vivo ligand binding assay, we predicted and confirmed that Scg3 selectively binds CNV vessels in both young and aged mice. In contrast, VEGF with minimal increased binding to CNV vessels exhibited an age-dependent decline in binding to both CNV and healthy vessels with negligible binding in aged mice. Based on …

Faculty, Staff and Students Publications

Objectives: Candida species are one of the most common causes of ICU-onset bloodstream infection (BSI). Yet, there is no robust guidance on when to initiate empiric antifungals for ICU patients suspected of BSI. We compared patients with ICU-onset candidemia vs. ICU-onset bacteremia to determine which patients may benefit from empiric antifungals.

Design: We compared characteristics between patients with bacteremia vs. candidemia at time of culture. We determined risk factors for death and constructed a multivariable regression to determine if candidemia is an independent risk factor for death.

Setting/patients: We included ICU patients from a hospital system in Houston, Texas (n …

The Hidden Link Between Endometriosis And Obesity: A State-Of-The-Art Review, Shefali N Desai, Christina C Reed, Yamely Mendez, Qiannan Yang, Xiaoming Guan

Faculty, Staff and Students Publications

Endometriosis remains an under-researched disease with a wide range of symptoms. Endometriosis reduces a woman's quality of life and professional productivity, yet its exact causes, risk factors, and treatment have yet to be elucidated. Body mass index and endometriosis have been observed to be inversely related; however, this relationship may only be a correlation rather than a causation. Obesity may play a role in the inflammation and cell proliferation associated with endometriosis through the complex signaling pathways of adipokines. A literature review was done on endometriosis and obesity to gain insight and synthesize knowledge about opportunities to improve endometriosis care, …

General Surgery, East Africa

Cancer constitutes one of the most urgent global health crises, with over 20 million new cases diagnosed annually worldwide, claiming 10 million lives. This devastating burden disproportionately affects vulnerable populations: 75% of cancer deaths occur in low- and middle-income countries despite these regions having lower reported incidence rates. Lung cancer leads the global toll, representing 12% of all cases but 19% of deaths, followed by breast cancer (12% of cases) and colorectal cancer (9.6%). A stark geographical inequity defines the cancer landscape—while wealthy regions such as North America, Northern Europe and Australia report the highest incidence rates, Africa and Latin …

Controlled Antibiotic Release From Emulsion-Loaded Alginate And Fibrin Hydrogels Using Ultrasound, Ziba Ghareh Nazi Fam, Asia Winslow, Mario Fabiilli, Sam Varghese, Brian Oeffinger, Flemming Forsberg, Noreen Hickok, Lauren Delaney

Department of Radiology Faculty Papers

Postoperative infections remain a major complication after spinal fusion surgery, often caused by biofilm-forming bacteria that resist short-term antibiotic prophylaxis. Vancomycin (VAN) is sometimes delivered locally during surgery; however, levels diminish rapidly, leaving patients vulnerable to late-onset infections. We developed a composite hydrogel integrating perfluorohexane-based emulsions within alginate or fibrin matrices to enable both sustained and ultrasound-triggered VAN release. Water-in-oil-in-water emulsions were prepared using fluorosurfactant-stabilized perfluorohexane as the volatile oil phase, then embedded in hydrogels and exposed to ultrasound (2.5 MHz, 5.5 MPa peak negative pressure) to initiate acoustic droplet vaporization for triggered release. Drug release was quantified spectrophotometrically and …
