Pediatric Obesity: Influence On Drug Dosing And Therapeutics, Barbara Ameer Pharmd, Mba, Bcps, Fcp, Michael Weintraub Md

Department of Medicine Faculty Papers

Obesity is an ongoing global health concern and has only recently been recognized as a chronic disease of energy homeostasis and fuel partitioning. Obesity afflicts 17% of US children and adolescents. Severe obesity (³120% of the 95th percentile of BMI-for-age, or a BMI of ³35 kg/m2) is the fastest growing subgroup and now approaches 6% of all US youth. Health consequences (e.g., type 2 diabetes, coronary heart disease) are related in a dose-dependent manner to severity of obesity. Since therapeutic interventions are less effective in severe obesity, prevention is a high priority.

School of Pharmacy Articles

BACKGROUND: Comparisons of clinical trial findings in systematic reviews can be hindered by the heterogeneity of the outcomes reported. Moreover, the outcomes that matter most to patients might be underreported. A core outcome set can address these issues, as it defines a minimum set of outcomes that should be reported in all clinical trials in a particular area of research. The objective in this study was to develop a core outcome set for clinical trials of medication review in multi-morbid older patients with polypharmacy.

METHODS: Firstly, eligible outcomes were identified through a systematic review of trials of medication review in ...


Semi-Synthesis Of A Novel Library Of Alkaloids As Potential Selective Analgesics, Brittany M. Gallagher 2018 Rowan University

Semi-Synthesis Of A Novel Library Of Alkaloids As Potential Selective Analgesics, Brittany M. Gallagher

Theses and Dissertations

Semi-synthetic compounds are an important part of the therapeutic drug discovery process. The goals of the project were to synthesize different generations of matrine analogues in order to gain many opportunities to manipulate the core structure. The long-term goal was, by manipulating the structure, the possibility to increase the biological activity of the original compound while also decreasing the toxicity. The first-generation matrine analogue allows for a synthesis similar to the Striker reaction producing aminonitriles. An alkyne coupling reaction was also possible with the modification, producing propargyl-amines. Both of the reactions resulted in the addition of a triple bond substituent ...

Cost-Effectiveness Analysis Of Metformin+Dipeptidyl Peptidase-4 Inhibitors Compared To Metformin+Sulfonylureas For Treatment Of Type 2 Diabetes, Christina S. Kwon, Enrique Seoane-Vazquez, Rosa Rodriguez-Monguio

Pharmacy Faculty Articles and Research

Background: Patients with type 2 diabetes (T2D) typically use several drug treatments during their lifetime. There is a debate about the best second-line therapy after metformin monotherapy failure due to the increasing number of available antidiabetic drugs and the lack of comparative clinical trials of secondary treatment regimens. While prior research compared the cost-effectiveness of two alternative drugs, the literature assessing T2D treatment pathways is scarce. The purpose of this study was to evaluate the long-term cost-effectiveness of dipeptidyl peptidase-4 inhibitors (DPP-4i) compared to sulfonylureas (SU) as second-line therapy in combination with metformin in patients with T2D.

Methods: A Markov ...
