SMU Data Science Review
In this paper, we present a novel framework and system for the identification of primary research topics from within a corpus of related publications, the classification of individual publications according to these topics, and the results of the application of our framework and system to the COVID-19 Open Research Dataset (CORD-19). CORD-19 is a corpus of published peer reviewed and pre-peer reviewed articles related to the coronavirus that causes COVID-19. Using machine learning techniques, such as Non-negative Matrix Factorization for Natural Language Processing and a Bayesian classifier, we developed a novel framework and system that automatically extracts sparse and meaningful …

Clopidogrel, the top prescribed antiplatelet medication for individuals who have experienced a myocardial infarction or cerebral vascular accident or who have peripheral arterial disease, is administered orally as a prodrug. It relies on hepatic metabolism through cytochrome P450 enzymes for conversion to its active form. Current research shows that allelic variation m the gene coding for CYP2C19 is the main factor contributing to the variability of response associated with clopidogrel treatment. Through the promotion of genetic testing for variability in the CYP2C19 gene and competently interpreting test results, pharmacists have the opportunity to use these findings to significantly impact clopidogrel …

Pharmacogenomics, the fusion of pharmacology and genomics, shows strong potential to solve many of today's dosing problems. lnter-patient dosing requirements, mainly due to genetic variability between patients, represent significant challenges for prescribers. Certain receptors, drug-targeted proteins, drug-transport mechanisms and drug-metabolizing enzymes are genetically established. Hence, any defect, absence or abnormality in the gene could alter how an affected individual will respond to a given drug. Due to advancements in technology, health care professionals who utilize pharmacogenomics may assess a patient's genetic profile and determine a predicted response to specific medications. This may result in potentially optimal dosing at the onset …

Antidepressant Dosing In Major Depression: A Pharmacogenomic Approach, Morgan Homan, Haval Norman, Victoria Cho, Yousif Rojeab
Pharmacy and Wellness Review
Major depressive disorder (MDD) is the most predominant mental disorder in the United States, with serious and costly health risks if not successfully managed. Pharmacotherapy is a standard option for MDD treatment, but patients often require extensive therapy adjustments to find a suitable regimen. Pharmacogenomics may enable greater precision in antidepressant therapy. Genotypic variations in CYP2D6 and CYP2C19 metabolic enzymes are reliable predictors of serum drug concentration, but the complex dose-response relationship of antidepressants prevents such variations from predicting therapy success. Additionally, ABCBl has been examined for its role in P-glycoprotein efflux of antidepressants in the brain, yet it is …

Pharmacy and Wellness Review
The programmed death-1 (PD-1) pathway has a significant role in the promotion of immune tolerance. The PD-1 receptor ligands are normally expressed on various inactive immune cells. When cancer cells express these ligands, they are able to interact with active T and B lymphocytes to induce this tolerance. Nivolumab and pembrolizumab are two recently approved agents that act to disrupt this binding and facilitate an immune response against cancer cells. Numerous trials, including KEYNOTE-002 and CheckMate 063, have demonstrated the superior safety and efficacy of these drugs in patients with advanced or refractory cancers. Initially approved for the treatment of …

Pharmacogenetics (PGt), the study of a gene's influence on patient response to a drug, shows strong potential for explaining issues with efficacy related to antidepressant medications. Each year, antidepressants are one of the most commonly prescribed medications due to the millions of Americans affected by depression. Importantly, it is recognized that there is wide interpatient variability in drug response to antidepressants caused by genetic mutations, which can alter the pharmacodynamic (PD) and pharmacokinetic (PK) properties of various drugs used to treat depression. Proteins that are mainly involved in how patients respond to medications include receptors, drug-targeted proteins, drug transport proteins …

Phenoconversion: Drug-Drug-Gene Interactions, Molly Kulp, Emily Limberg, Brooke Marlowe, Taylor Roberson, David F. Kisor
Pharmacy and Wellness Review
Based on the extensive, poor, intermediate and ultrarapid phenotypes of patients, inferences may be made relative to drug metabolism, ultimately leading to changes in therapeutic drug choice or dosing. Phenoconversion is a phenomenon that occurs when an individual's drug metabolizing capacity is altered due to the combination of a drug-drug interaction and a drug-gene interaction. Phenoconversion can affect pharmacokinetics as well as pharmacodynamics. Some examples of phenoconversions include amiodarone-warfarin, duloxetine-codeine, rifampin-clopidogrel, and rifampinwarfarin. Pharmacists must consider phenoconversion in cases of multi-drug therapy.

Pharmacy and Wellness Review
Cystic fibrosis (CF) is a genetic disease associated with specific gene mutations that presents with pulmonary inflammation and frequent lung infections, exocrine pancreatic insufficiency, altered sweat composition and declining lung function. Ivacaftor (Kalydeco®) was approved for treatment of cystic fibrosis in patients 6 years of age and older with a G551D mutation on the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a CFTR potentiator and does not work in patients with a mutation of the F508del. Efficacy has been demonstrated in several trials with a primary outcome of improved FEV1, improvements in pulmonary exacerbations, patient-reported decrease in respiratory …

Incorporation of pharmacogenomic data into Medication Therapy Management (MTM) allows pharmacists to optimize treatment regimens for patients leading to better overall outcomes. Utilizing pharmacogenomics makes it easier for health care professionals to initiate medication regimens with reduced adverse reactions, improves outcomes due to specialized dosing and therapies and allows the treatment process to be as cost-effective as possible for the patient. Pharmacists have an opportunity to educate the rest of the health care team on issues such as: which ethnicities possess higher odds of carrying certain genetic variants, the most common or most relevant medications that can have variable effects …

The Impact Of Pharmacogenomics On Chemotherapeutic Drug Development And Use, Lara Long, Amy Pasternak, Ellen Hazelet, David Kisor
Pharmacy and Wellness Review
Cancer therapy is largely dependent on general treatment guidelines, and patients undergoing chemotherapy often experience treatment failure with standard drugs. The development of individualized drug therapy through pharmacogenomics has the potential to enhance chemotherapy regimen selection and improve patient outcomes. Antineoplastic agents such as cetuximab and trastuzumab are effective in treating cancers possessing specific genetic biomarker characteristics. Patients need to undergo genetic testing before these agents are administered to ensure appropriate use. Cetuximab has been shown to improve outcomes in metastatic colorectal cancers and head and neck squamous cell carcinomas positive for EGFR. Trastuzumab has shown benefit in human epidermal …

Journal of Patient-Centered Research and Reviews
Precision medicine is a term describing strategies to promote health and prevent and treat disease based on an individual’s genetic, molecular, and lifestyle characteristics. Oncology precision medicine (OPM) is a cancer treatment approach targeting cancer-specific genetic and molecular alterations. Implementation of an OPM clinical program optimally involves the support and collaboration of multiple departments, including administration, medical oncology, pathology, interventional radiology, genetics, research, and informatics. In this review, we briefly introduce the published evidence regarding OPM’s potential effect on patient outcomes and discuss what we have learned over the first year of operating an OPM program within an integrated health …
