Abstract
Pharmacovigilance improves patient safety by detecting and preventing adverse drug events. However, challenges exist that limit adverse drug event detection, resulting in many adverse drug events being underreported or inaccurately reported. One challenge includes having access to large data sets from various sources including electronic health records and wearable medical devices. Artificial intelligence, including machine learning methods, such as natural language processing and deep learning, can detect and extract information about adverse drug events, thus automating the pharmacovigilance process and improving the surveillance of known and documented adverse drug events. In addition, with the increased demand for telehealth services, for managing both acute and chronic diseases, artificial intelligence methods can play a role in detecting and preventing adverse drug events. In this review, we discuss two use cases of how artificial intelligence methods may be useful to improve the quality of pharmacovigilance and the role of artificial intelligence in telehealth practices.

Abstract
Purpose Dietary supplements (DSs) are popular in many countries, and their use among individuals is increasing worldwide. Therefore, this study aimed to assess the prevalence and use of DSs among pharmacy students in King Saud University College of Pharmacy, Riyadh, Saudi Arabia. Methods This study used a cross-sectional design targeting male senior pharmacy students in their fourth and fifth years of Bachelor and Doctor of Pharmacy courses. The data were collected between August and October 2019 using paper-based questionnaires. Results A total of 46.8% of the students used DSs. Of all students surveyed, 19% used branded supplements whereas 9.7% used generic or local supplements and 12.3% used both generic and branded supplements. Furthermore, 8.2% students suffered from side effects, including 5.6% who suffered from nausea, vomiting, and diarrhea and 2.6% who suffered from headache, confusion, and disorientation. Approximately 24.6% of students used fiber DSs whereas 19% and 16.4% used DSs for protein and glucosamine/omega 3 fatty acids, respectively. Conclusion The study findings indicated that the prevalence of DS use is increasing. However, approximately half of the respondents encourage the use of DSs only with a doctor’s recommendation. Educating about the safe use of DSs is warranted.

Abstract
The use of doping substances and methods is extensive not only among elite athletes, but also among amateur and recreational athletes. Many types of drugs are used by athletes to enhance performance, to reduce anxiety, to increase muscle mass, to reduce weight or to mask the use of other drugs during testing. However, the abuse of doping substances and methods has been associated with the occurrence of numerous health side-effects. The adverse effects depend on the type of the consumed drug, as well as the amount and duration of intake and the sensitivity of the body, since there is a large inter-individual variability in responses to a drug. Usually the doses used in sports are much higher than those used for therapeutic purposes and the use of several drugs in combination is frequent, leading to higher risk of side-effects. Among biomedical side-effects of doping, the cardiovascular ones are the most deleterious. Myocardial infarction, hyperlipidemia, hypertension, thrombosis, arrythmogenesis, heart failure and sudden cardiac death have been noted following drug abuse. This paper reviews the literature on the adverse cardiovascular effects after abuse of prohibited substances and methods in athletes, aiming to inform physicians, trainers and athletes and to discourage individuals from using drugs during sports.

Abstract
PURPOSE The severity of hazards posed by medications implicated in poisoning in older adults was characterized. METHODS Toxic Exposure Surveillance System (TESS) cases from 1993 through 2002 involving a single substance in patients age 60 years or older and coded as an adverse drug reaction (ADR) or therapeutic error were analyzed. Hazard factors were determined for each exposure reason by calculating the sum of the major effects and deaths for each substance category and subcategory and dividing this by the total number of exposures for the respective category or subcategory. RESULTS Hazard factors were calculated for 12,737 ADRs and 51,846 therapeutic errors. The overall rates of major effects and deaths were 7.5% and 1.6% in the ADR and therapeutic error groups, respectively. In the ADR group, five TESS categories had a hazard factor of > or =2.0: anesthetics, anticoagulants, antineoplastics, cardiovascular drugs, and radiopharmaceuticals. In the therapeutic error group, five drug categories also had a hazard factor of > or =2.0: anesthetics, anticoagulants, antineoplastics, asthma therapies, and serums/toxoids/vaccines. Six pharmaceutical categories were associated with hazard factors of > or =2.0 in both the ADR and therapeutic error groups. CONCLUSION An analysis of ADRs and therapeutic errors involving older adults and reported to poison control centers from 1993 through 2002 revealed overall rates of major effects and death of 7.5% and 1.6% in the ADR and therapeutic error groups, respectively. Antineoplastics, aminophylline or theophylline, cardiac glycosides, heparin, morphine, and warfarin were implicated in more than 50 cases and associated with hazard factors of > or =2.0 for both exposure groups.

Abstract
OBJECTIVE To examine information collected from the 2002 Health and Diet Survey regarding the use dietary supplements and self-reported health problems that the survey participants believed were related to dietary supplements. METHODS The US Food and Drug Administration sponsors a Health and Diet Survey to track trends of consumer awareness, attitudes, and practices related to health and diet issues. By telephone, the 2002 Health and Diet Survey staff interviewed English-speaking noninstitutionalized adults aged 18 years or older in households in the 50 states and District of Columbia. Survey respondents were queried as to whether or not they had taken a dietary supplement during the past year and if they had experienced any health problem that they attributed to supplement use. RESULTS Seventy-three percent of US noninstitutionalized adults aged 18 years or older who spoke English and resided in households with telephones used a dietary supplement in the previous 12 months and 4% of them had experienced an adverse event that they believed might be related to dietary supplement use. Eighty-five percent of supplement users reported taking multivitamins/multiminerals and 13.3% of adverse events reported were attributed to multivitamins/multiminerals. A higher proportion of supplement users with adverse events than users without adverse events were concurrently taking supplements and prescription drugs or were taking supplements instead of prescription drug to treat or prevent a health condition. CONCLUSIONS This self-reported data describes the prevalence of supplement use and related adverse events. Multivitamins/multiminerals accounted for much of the supplements use and was attributed to a little more than 10% of the adverse events reported. Food and nutrition-professionals and other health care professionals should take special care to learn about their patients' use of these products.

Abstract
Many life-threatening drug interactions are predictable, avoidable events. Emergency medicine physicians have a responsibility to recognize and prevent drug interactions. Keeping current on the many pharmaceutical therapies,their pharmacology, and potential drug interactions currently represents one of the biggest challenges for emergency medicine practitioners. Using current drug interaction resources and knowing the limited number of medications that are responsible for the most serious drug interactions can ease this seemingly overwhelming burden greatly. Clinicians need to be particularly vigilant when prescribing drugs for patients who are taking medications with potential for drug interactions leading to serious consequences.

Abstract
To safely use medications, professionals and consumers need usable and reliable methods to identify tablets patients are prescribed and taking. Currently, each manufacturer assigns its own identifying codes and symbols. Standardization of the system for identifying solid dosage forms is a goal that has been widely advocated, yet stubbornly resistant to progress. Physicians, pharmacists, and consumers attempting to identify pills must use various methods which have shortcomings in ease of use, availability, and accuracy. Arguments have been advanced, particularly by pharmaceutical manufacturers, that evidence of unworkability of the current system is not compelling, and costs of retooling current manufacturing processes could be prohibitive. These issues are currently being explored by a task force led by the U.S. Pharmacopeia Safe Medication Use, and Pharmaceutical Forms Dosage Expert Committees. This paper presents a fictitious case study of an elderly patient succumbing to digoxin overdose illustrating the dilemmas posed in the tablet-imprint debate.

Abstract
Adverse drug reactions (ADRs) and iatrogenic diseases have been identified as significant factors responsible for patient morbidity and mortality. Significant studies on drug metabolism in humans have been published during the last few years, offering a deeper comprehension of the mechanisms underlying adverse drug reactions and interactions. More understanding of these mechanisms, and of recent advances in laboratory technology, can help to evaluate potential drug interactions when drugs are prescribed concurrently. Increasing knowledge of interindividual variation in drug breakdown capacity and recent findings concerning the influence of environment, diet, nutrients, and herbal products can be used to reduce ADRs and iatrogenic diseases. Reviewed data suggest that drug treatment should be increasingly custom tailored to suit the individual patient and that appropriately co-prescribed diet and herbal remedies, could increase drug efficacy and lessen drug toxicity. This review focuses mainly on recently published research material. The cytochrome p450 enzymes, their role in metabolism, and their mechanisms of action are reviewed, and their role in drug-drug interactions are discussed. Drug-food and drug-herb interactions have garnered attention. Interdisciplinary communication among medical herbalists, medical doctors, and dietetic experts needs to be improved and encouraged. Internet resources for obtaining current information regarding drug-drug, drug-herb, and drug-nutrient interactions are provided.

Abstract
OBJECTIVE The purpose of this study was to compare poisoning mortality rates of states served by a poison control center certified by the American Association of Poison Control Centers (AAPCC) to those that are not served by a certified center because health policy has been based on certification status. METHODS Poisoning mortality rates from 1993 to 1997 were obtained from a public use database of death certificates and were stratified by state and circumstance. Each state was classified as being fully served, partially served, or not served by an AAPCC-certified center. States in one category of service for the entire 5 years were selected for analysis. RESULTS During this 5-year period, 39 states exhibited a consistent category of poison control center services. The mortality rates per 100,000 population during these 5 years were 5.93, 6.12, 6.01, 6.23, and 6.68 respectively (P <0.05) for all 39 states. The mean 5-year mortality rate for states with certified poison control center services (7.08 +/- 2.59; n = 17) was higher (P <0.05) than those with noncertified service (5.17 +/- 1.46; n = 15) but not significantly different from those with partial certified service (6.25 +/- 1.75; n = 7). CONCLUSION Increased poisoning mortality rates were associated with AAPCC certification status and year. Poisoning mortality rates may not be an appropriate outcome measure of the impact of poison control centers, AAPCC-certification notwithstanding, at this time. Basing poison control center-related policy on state-specific poisoning mortality rates can not be supported by these findings.

Abstract
BACKGROUND Dietary supplements that contain ephedra alkaloids (sometimes called ma huang) are widely promoted and used in the United States as a means of losing weight and increasing energy. In the light of recently reported adverse events related to use of these products, the Food and Drug Administration (FDA) has proposed limits on the dose and duration of use of such supplements. The FDA requested an independent review of reports of adverse events related to the use of supplements that contained ephedra alkaloids to assess causation and to estimate the level of risk the use of these supplements poses to consumers. METHODS We reviewed 140 reports of adverse events related to the use of dietary supplements containing ephedra alkaloids that were submitted to the FDA between June 1, 1997, and March 31, 1999. A standardized rating system for assessing causation was applied to each adverse event. RESULTS Thirty-one percent of cases were considered to be definitely or probably related to the use of supplements containing ephedra alkaloids, and 31 percent were deemed to be possibly related. Among the adverse events that were deemed definitely, probably, or possibly related to the use of supplements containing ephedra alkaloids, 47 percent involved cardiovascular symptoms and 18 percent involved the central nervous system. Hypertension was the single most frequent adverse effect (17 reports), followed by palpitations, tachycardia, or both (13); stroke (10); and seizures (7). Ten events resulted in death, and 13 events produced permanent disability, representing 26 percent of the definite, probable, and possible cases. CONCLUSIONS The use of dietary supplements that contain ephedra alkaloids may pose a health risk to some persons. These findings indicate the need for a better understanding of individual susceptibility to the adverse effects of such dietary supplements.
