Role of Thromboelastography Platelet Mapping and International Normalized Ratio in Defining "Normocoagulability" During Anticoagulation for Mechanical Circulatory Support Devices: A Pilot Retrospective Study.

Thromboembolic (TE) events and hemorrhagic complications continue to remain as frequent adverse events and causes of death after mechanical circulatory support device (MCSD) implantation. To counterbalance this postimplant multifactorial hypercoagulable state, antithrombotic therapy given postimplant must be individually tailored to keep patient adequately anticoagulated yet normocoagulable. Prior studies describing different anticoagulation protocols do not define normocoagulability for patients on MCSDs. We evaluated the role of thromboelastography platelet mapping (TEG PM) in defining "normocoagulability" for MCS patients on anticoagulant (warfarin) and antiplatelet agents. Ninety-eight MCSD patients who underwent TEG PM assay at our institution from 2012 to 2014 were included for retrospective analysis. Eleven (11.2%) subjects developed at least one TE event during the study period. Of the 13 TE events, 8 occurred in patients with total artificial heart (TAH). TEG parameters closest to the event or when patient was clinically adequately anticoagulated and corresponding international normalized ratio (INR) were measured. Thromboelastography coagulation index (CI) appears to be the single most statistically significant parameter that can be used to designate a patient as normocoagulable. Based on our results, patients with HeartMate II (HM II) and Heart Ware (HW) devices should be maintained at a CI value of less than or equal to 1.5 whereas patients with TAH devices should be maintained at a CI less than or equal to 1.2. The CI should be correlated with the degree of Vitamin K-dependent coagulation factor inhibition that is achieved using device-specific goal INR ranges. A recent modification, TEG PM assesses the effects of antiplatelet drug. Maximal amplitude arachidonic acid (MA-AA) < 50 and maximal amplitude adenosine diphosphate (MA-ADP) < 50 are desired for normocoagulable state.

Performance-enhancing drugs: understanding the risks.

To help clinicians understand the risks associated with performance-enhancing drugs, this overview covers prohibited lists of substances and methods, therapeutic use exemptions, the legitimate indications and adverse effects, including for megadose and polypharmacy doping of stimulants, anabolic steroids, erythropoiesis-stimulating agents, and growth hormone and ways in which physicians or patients risk committing anti-doping rule violations inadvertently.

Availability of tobacco and alcohol products in Los Angeles community pharmacies.

The availability of tobacco and alcohol products in community pharmacies contradicts the pharmacists' Code of Ethics and presents challenges for a profession that is overwhelmingly not in favor of the sale of these products in its practice settings. The primary aim of this study was to estimate the proportion of pharmacies that sell tobacco products and/or alcoholic beverages and to characterize promotion of these products. The proportion of pharmacies that sell non-prescription nicotine replacement therapy (NRT) products as aids to smoking cessation also was estimated. Among 250 randomly-selected community pharmacies in Los Angeles, 32.8% sold cigarettes, and 26.0% sold alcohol products. Cigarettes were more likely to be available in traditional chain pharmacies and grocery stores than in independently-owned pharmacies (100% versus 10.8%; P < 0.001), and traditional chain drug stores and grocery stores were more likely to sell alcoholic beverages than were independently-owned pharmacies (87.5% vs. 5.4%; P < 0.001). Thirty-four (41.5%) of the 82 pharmacies that sold cigarettes and 47 (72.3%) of the 65 pharmacies that sold alcohol also displayed promotional materials for these products. NRT products were merchandised by 58% of pharmacies. Results of this study suggest that when given a choice, pharmacists choose not to sell tobacco or alcohol products.

Educational opportunities and anti-doping roles and responsibilities for pharmacists.

Drug use and abuse by athletes has become a common problem. Pharmacists can assist by managing the legitimate medication needs of athletes to prevent them from accidentally using a banned substance. Pharmacists can also educate athletes and the public about the health consequences of using performance-enhancing substances. Pharmacists can play a variety of roles to assist with anti-doping. Such roles include educating, advising, dispensing and monitoring medications and supplements; and working with anti-doping agencies. There are few established educational opportunities for pharmacists and pharmacy students. Educational programs in sports pharmacy and doping control need to be developed for instruction in the classroom, for post-graduate training and for experiential programs. Classroom instruction should include information about performance-enhancing substances and general principles of doping control. Student activities for an established advanced pharmacy practice experience include education on performance-enhancing substances and assay technologies, preparing and providing presentations to athletes and others regarding these substances, performing literature research on drugs and dietary supplements used to improve athletic performance, writing a monograph on these substances, and participating in doping control programs.

High-dose carisoprodol during pregnancy and lactation.

OBJECTIVE: To report a case of use of high-dose carisoprodol during pregnancy and breast-feeding. CASE SUMMARY: A 28-year-old woman with severe back muscle spasm took carisoprodol 2800 mg/day before and throughout an uncomplicated pregnancy and while exclusively breast-feeding her infant during the first month after birth. Serum drug concentrations of carisoprodol and the active metabolite meprobamate were measured in the mother and infant. Concentrations of these agents also were measured in breast milk. Developmental toxicity was not observed in the near-term infant, whose birth weight was at the 10th percentile for gestational age. Only slight sedation was noted in the infant during breast-feeding, and no signs or symptoms of withdrawal were noted when nursing was stopped. DISCUSSION: Carisoprodol and meprobamate are excreted into breast milk. Although the published human pregnancy data are limited to 15 cases, carisoprodol does not appear to cause developmental toxicity (growth restriction, structural anomalies, functional/neurobehavioral deficits, or death), even when the mother is taking high doses. No signs or symptoms of withdrawal were noted in our infant or in a previously published case when breast-feeding was stopped. Long-term follow-up has not been conducted in exposed infants, and the possibility of functional/neurobehavioral l deficits appearing later in life cannot be excluded. CONCLUSIONS: Except for mild sedation, no other toxicity was observed in a near-term infant exposed to carisoprodol throughout gestation and during breast-feeding in the first month after birth.
