Low-dose aspirin is recommended for prevention of hypertensive disorders of pregnancy (HDP) and preterm birth (PTB) in high-risk pregnancies. There is limited data on factors impacting aspirin response in pregnancy. We aimed to evaluate predictors of aspirin response and association with pregnancy outcome with a prospective study of high-risk pregnancies taking 81 mg aspirin daily. Aspirin response was evaluated with Platelet Function Assay-100 (PFA-100) epinephrine closure time at baseline (< 16 weeks' gestation), follow-up 1 (2-4 weeks after aspirin initiation), and follow-up 2 (28-32 weeks gestation). Multivariable regression was used to identify factors associated with PFA-100 at each visit, and results presented with beta coefficient (B) and confidence interval. The median difference (MD) in PFA-100 in those with and without HDP or PTB was compared. Results included 108 who completed follow-up 1 and 96 who completed both visits with > 75% adherence. PFA-100 was increased from baseline at follow-ups 1 and 2 (MD 37 (27-49); MD 26 (15.5-38.5) respectively). At follow-up 1, obesity (B = -30 (-53 to -7) seconds), …

Putting The Substance In Substantial Evidence: An Evidence-Based Approach To Flexible Drug Regulation, Emanuel Krebs, Tania M. Bubela, Melanie Mcphail, Christopher Mccabe, Dean A. Regier

Office of the Provost

For new drugs or indications, substantial evidence of clinical effectiveness is required for market authorization. In most jurisdictions, substantial evidence is not explicitly defined. Health regulators exercise discretion and are increasingly tolerant of earlier or less mature evidence. To align with flexible evidentiary standards, we argue for the adoption of a principle and, context-based approach to the evidence threshold. Our approach aims to balance the potential benefits and harms of accelerated authorization, low therapeutic value, and safety, based on a value of information (VoI) framework. In our VoI framework, substantial evidence exists when the expected net health value of further …

Antiseizure Medications And Their Differing Effects On Cardiovascular Risk, Aleena Abbasi, Bassil Abbasi, Scott Mintzer, Carla Lopinto-Khoury

Department of Neurology Faculty Papers

This review discusses the differing effects of enzyme-inducing and non-inducing antiseizure medications on cardiovascular risk and their implications for the management strategies of epilepsy patients. Traditional risk markers, including low density lipoprotein, high density lipoprotein and triglycerides, can be altered by both enzyme induction and inhibition. Other markers of vascular risk, including c-reactive protein, non-high-density lipoprotein and homocysteine, are affected by antiseizure medications, although adults and children may have different responses. The overall atherosclerotic risk picture is more complex due to indirect effects such as neuroendocrine function and the metabolic syndrome. Large scale data shows an evolving understanding of cardiovascular …

Saudi Toxicology Journal

Tamoxifen is a cornerstone therapy for estrogen receptor-positive (ER+) breast cancer, improving survival and reducing recurrence. Its efficacy and toxicity, however, vary due to genetic polymorphisms influencing metabolism and transport. Key genes, such as CYP2D6, CYP3A4, and ATP-binding cassette transporters (ABCB1, ABCC2), are crucial in forming and distributing active metabolites like endoxifen. This review explores tamoxifen pharmacogenetics through an analysis of literature from PubMed, Scopus, Google Scholar, and PharmaGKB. Genetic variations like CYP2D6*10 in Asians and CYP2D6*17/29 in Africans impact therapeutic outcomes. Barriers to personalized tamoxifen therapy include inconsistent guidelines, limited access to genetic testing, and underrepresentation of ethnic groups …

Improving The Safety Of N,N-Dimethylacetamide As A Potential Treatment For Preterm Birth Using A Vaginal Nanoformulation, Asad Mir

Theses and Dissertations

With no available treatment for preterm birth, the field of reproductive medicine has been repurposing small molecule candidates into vaginal nanoformulations as potential treatments for the condition. The commercial solvent N,N-Dimethylacetamide (DMA) has previously been shown to delay and prevent inflammation-induced preterm birth in a mouse model. A vaginal nanoformulation of DMA loaded into a self-nanoemulsifying drug delivery system (SNEEDS) was studied to see if it can also be efficacious. A side by-side histological comparison was done in the more pertinent tissues of the reproductive tract between the traditional formulation of DMA given intraperitoneally (IP) and the vaginal nanoformulation of …
