Research, Publications & Creative Work

Ewing sarcoma (ES) is a high-grade bone and soft tissue tumor in adolescents and young adults. Cytotoxic chemotherapy does not improve prognosis, especially for advanced ES patients who have a 5-year survival of 30% or less [1, 2]. Molecular targeted therapy emerges as a promising strategy to battle ES, given its unique driver mutations resulting from the fusion of the EWS and one of the ETS genes, but the feasibility of directly blocking EWS-ETS function has not yet been established [3]. To search for new therapeutic targets, we began with an analysis of the Cancer Dependency Map (DepMap) datasets that …

Gut inflammatory diseases cause microbial dysbiosis. Human immunodeficiency virus-1 (HIV) infection disrupts intestinal integrity, subverts repair/renewal pathways, impairs mucosal immunity and propels microbial dysbiosis. However, microbial metabolic mechanisms driving repair mechanisms in virally inflamed gut are not well understood. We investigated the capability and mechanisms of gut microbes to restore epithelial barriers and mucosal immunity in virally inflamed gut by using a multipronged approach: an in vivo simian immunodeficiency virus (SIV)-infected nonhuman primate model of HIV/AIDS, ex vivo HIV-exposed human colorectal explants and primary human intestinal epithelial cells. SIV infection reprogrammed tryptophan (TRP) metabolism, increasing kynurenine catabolite levels that are …

Methodological And Clinical Concerns In The Study On Postpartum Hypertension Management, Takaki Tanamoto, Kyosuke Kamijo, Yusuke Tsutsumi, Tetsuya Kawakita Jan 2025

Methodological And Clinical Concerns In The Study On Postpartum Hypertension Management, Takaki Tanamoto, Kyosuke Kamijo, Yusuke Tsutsumi, Tetsuya Kawakita

Department of Obstetrics & Gynecology Faculty Publications

[Introduction] We read with interest the recent study by Rosenfeld et al.¹ However, we have several clinical and methodological concerns about this study.¹

First, this study's propensity score matching (PSM) lacked key clinical confounders, including perinatal risk factors and the highest systolic/diastolic blood pressures. Smoking, alcohol use, and multifetal gestation, which influence blood pressure during pregnancy,²,³ potentially affect both primary and secondary outcomes. Additionally, the authors did not report standardized mean differences before and after PSM, which are essential for assessing balance.⁴
