Hepatic Manifestations Following Gene Therapy, Akash Roy, Shalini Bansal, Anand Kulkarni, K. Rajender Reddy

SKMC Student Presentations and Publications

Gene therapy involves the introduction of genetic materials, most commonly using viral vectors, to alter gene expression to ameliorate or cure disease symptoms with minimal adverse events. While interest in gene therapy has been on the increase, concerns have arisen about the potential for hepatotoxicity, which arises from diverse mechanisms. While viral vectors can produce dose-dependent hepatotoxicity secondary to integration, immune responses appear to be the primary driving mechanism. A mild increase in aminotransferases is the most common hepatic manifestation, occurring variably in 20%-80%, while there has been rare progress to acute liver failure. The occurrence of hepatotoxicity is unpredictable …

Supercharged And Delayed Thoracodorsal And Dorsal Intercostal Artery Perforator Flaps For Autologous Breast Reconstruction, Adeem M. Nachabe, Mohammed S. Rais, Mark A. Maier, Hugo St Hilaire, Robert J. Allen

School of Medicine Faculty Publications

In patients seeking total autologous breast reconstruction following mastectomy, prior abdominal surgery can present as a contraindication to utilizing traditional abdominal-based free flaps. The thoracodorsal artery perforator (TDAP) flap has emerged as a suitable alternative, providing adequate tissue and minimal donor site morbidity. This case report demonstrates further improvement to this technique by utilizing the dorsal intercostal artery perforator vessels to supercharge this pedicled flap, along with a surgical delay of the TDAP and dorsal intercostal artery perforator. This adaptation can provide added bulk and improved perfusion to the traditional TDAP-based total autologous breast reconstruction.

Hypertensive disorders of pregnancy (HDP), including preeclampsia, affect 1 in 6 pregnancies, are major contributors to maternal morbidity and mortality, yet lack precision medicine strategies. Analyzing transcriptomic data from a prospectively-collected diverse cohort (n = 9102), this study reveals distinct RNA subtypes in maternal blood, reclassifying clinical HDP phenotypes like early/late-onset preeclampsia. The placental gene PAPPA2 strongly predicts the most severe forms of preeclampsia in individuals without pre-existing high risk factors, months before symptoms, and its overexpression correlates with earlier delivery in a dose-dependent manner. Further, molecular subtypes characterized by immune genes are upregulated in less severe forms of HDP. …
