Condensing these broad, complex changes into one index would greatly facilitate the clinical usage of gut microbiome data. Here, we formulated a gut microbiota index in patients with acute ischemic stroke based on their gut microbiota dysbiosis patterns and tested whether the index was correlated with brain injury and early outcome. Methods: A total of 104 patients with acute ischemic stroke and 90 healthy individuals were recruited, and their gut microbiotas were compared and to model a Stroke Dysbiosis Index (SDI), which representing stroke-associated dysbiosis patterns overall. Another 83 patients and 70 controls were recruited for validation. ...

Authors: Teng M, Zhou S, Cai C, Lupien M, He HH Abstract Prostate cancer is the most commonly diagnosed non-cutaneous cancers in North American men. While androgen deprivation has remained as the cornerstone of prostate cancer treatment, resistance ensues leading to lethal disease. Forkhead box A1 (FOXA1) encodes a pioneer factor that induces open chromatin conformation to allow the binding of other transcription factors. Through direct interactions with the Androgen Receptor (AR), FOXA1 helps to shape AR signaling that drives the growth and survival of normal prostate and prostate cancer cells. FOXA1 also possesse...

AbstractPurposeTo evaluate the effects of epiretinal membrane (ERM) formation on the anatomic and functional results of subjects with diabetic macular edema (DME) who are receiving intravitreal aflibercept injections (IAIs).Materials and methodsThis retrospective comparative study includes 29 eyes with DME (Group 1) and 43 eyes with DME and ERM (Group 2). After three consecutive monthly 2.0  mg IAIs, subjects received monthly follow-ups and retreatment was performed if needed. Corrected visual acuity (CVA), central macular thickness (CMT), and central macular volume (CMV) parameters were recorded tri-monthly, and the ...
