Comparison of Postoperative Bleeding in Total Hip and Knee Arthroplasty Patients Receiving Rivaroxaban, Enoxaparin, or Aspirin for Thromboprophylaxis

Background: Guidelines recommend the use of multiple pharmacologic agents and/or mechanical compressive devices for prevention of venous thromboembolism, but preference for any specific agent is no longer given in regard to safety or efficacy. Objective: To compare postoperative bleeding rates in patients receiving enoxaparin, rivaroxaban, or aspirin for thromboprophylaxis after undergoing elective total hip arthroplasty or total knee arthroplasty. Methods: This retrospective cohort analysis evaluated patients who received thromboprophylaxis with either enoxaparin, rivaroxaban, or aspirin. All data were collected from the electronic medical record. The primary outcome was any postoperative bleeding. Results: A total of 1244 patients were included with 366 in the aspirin, 438 in the enoxaparin, and 440 in the rivaroxaban arms. Those who received aspirin or enoxaparin were less likely to experience any bleeding compared to those patients who received rivaroxaban (P \u3c.05). There was also a lower rate of major bleeding in these groups, but the differences were not significant. Conclusions: Aspirin and enoxaparin conferred similar bleeding risks, and both exhibited less bleeding than patients who received rivaroxaban

Multicenter, Observational Cohort Study Evaluating Third-Generation Cephalosporin Therapy for Bloodstream Infections Secondary to Enterobacter, Serratia, and Citrobacter Species

Objectives: There is debate on whether the use of third-generation cephalosporins (3GC) increases the risk of clinical failure in bloodstream infections (BSIs) caused by chromosomally-mediated AmpC-producing Enterobacterales (CAE). This study evaluates the impact of definitive 3GC therapy versus other antibiotics on clinical outcomes in BSIs due to Enterobacter, Serratia, or Citrobacter species. Methods: This multicenter, retrospective cohort study evaluated adult hospitalized patients with BSIs secondary to Enterobacter, Serratia, or Citrobacter species from 1 January 2006 to 1 September 2014. Definitive 3GC therapy was compared to definitive therapy with other non-3GC antibiotics. Multivariable Cox proportional hazards regression evaluated the impact of definitive 3GC on overall treatment failure (OTF) as a composite of in-hospital mortality, 30-day hospital readmission, or 90-day reinfection. Results: A total of 381 patients from 18 institutions in the southeastern United States were enrolled. Common sources of BSIs were the urinary tract and central venous catheters (78 (20.5%) patients each). Definitive 3GC therapy was utilized in 65 (17.1%) patients. OTF occurred in 22/65 patients (33.9%) in the definitive 3GC group vs. 94/316 (29.8%) in the non-3GC group (p = 0.51). Individual components of OTF were comparable between groups. Risk of OTF was comparable with definitive 3GC therapy vs. definitive non-3GC therapy (aHR 0.93, 95% CI 0.51–1.72) in multivariable Cox proportional hazards regression analysis. Conclusions: These outcomes suggest definitive 3GC therapy does not significantly alter the risk of poor clinical outcomes in the treatment of BSIs secondary to Enterobacter, Serratia, or Citrobacter species compared to other antimicrobial agents

Intravenous and Inhaled Antimicrobials at Home in Cystic Fibrosis Patients

The primary clinical characteristics of cystic fibrosis (CF) are malnutrition caused by malabsorption secondary to pancreatic insufficiency, chronic pulmonary infections, and male infertility. The major cause of morbidity and mortality are bronchiectasis and obstructive pulmonary disease. Lung disease in CF is manifested by this chronic lung disease progression, with intermittent episodes of acute worsening of symptoms called pulmonary exacerbations. Once the patient has stabilized, and if suitable care can be arranged, these interventions are often transitioned to the home. This review summarizes important points pertinent to the use of intravenous and inhaled antimicrobials that may be encountered by prescribers, nurses, technicians, and case managers in the home health setting. Appropriate dosing, indications, adverse drug reactions, monitoring parameters, and practicality of both intravenous and inhaled antimicrobials are discussed

Perception of Natural Therapies Following Student-Led Education

Objective: This pilot study sets out to discover the consumer\u27s attitudes and perceptions about herbal therapy-both before and after viewing student pharmacists\u27 posters that included information on various supplements and herbal therapies. Methods: An eleven-question survey was distributed among 61 attendees. In addition to demographic information, questions were asked about opinions of safety and efficacy of natural supplements and herbal therapies. Additionally, respondents were asked about their intended future use of herbal therapies. Results: Twenty-four percent of the survey respondents changed their perception regarding the safety of natural and herbal therapies, (p = 0.23), while 45fc changed their perception of efficacy (p = 0.012). Overall, there was not an anticipated change in the use of natural and herbal therapies among the respondents. Prior use of or familiarity with natural or herbal products did not influence future anticipated use. Conclusion: Student pharmacists\u27 poster presentations significantly changed the perception regarding the efficacy of dietary supplements, but not the perception of safety

Insulin Therapy in Home Health: A Review

Diabetes mellitus, whether type 1 or type 2, offers special challenges to home health care providers. Treatment of diabetes can become increasing complex. While insulin remains the cornerstone of treatment in patients with type 1 diabetes (T1DM), the utilization of insulin to safely control blood glucose is also necessary for many patients with type 2 diabetes (T2DM). Many different insulin products are available, with each product possessing different characteristics and adverse effect potential. Balancing glycemic control with patient safety is paramount. The individualization of insulin therapy can be challenging for both patients and health care professionals. Regular evaluation of blood glucose monitoring is vital for patient assessment. This article provides a review of insulin for providers caring for patients in the home health care setting

Therapeutic Management of Accidental Epinephrine Injection

Objective: To review the literature regarding therapeutic options for accidental epinephrine exposure via EpiPen (Mylan Specialty Inc.) autoinjector devices and to suggest a treatment algorithm based on the most common approaches found therein. Data Sources: A literature search of MEDLINE (1950-March 2012) was conducted, using the search term accidental epinephrine injection in combination with the terms adrenaline, EpiPen, anaphylaxis, autoinjector, and treatment. Case reports, case series, and systematic reviews were evaluated for efficacy and safety data. In addition, the references of the reviewed articles were examined to identify additional reports or data. Study Selection and Data Extraction: All English-language articles describing accidental exposure to epinephrine were identified. Our search included both pediatric and adult patient populations. Articles were excluded if the exposure to epinephrine was purposeful and the EpiPen described in the report was being used as intended or the outcome was not clear. Individual case reports were described in detail whereas case series and systematic reviews were included but were not described in detail. To our knowledge, there have been no clinical trials that describe or compare therapeutic options for accidental exposure to epinephrine. Data Synthesis: Accidental exposure to epinephrine is an underreported phenomenon that could warrant medical attention. The importance of this issue has recently been emphasized with the legislative requirement of many schools to store epinephrine (EpiPen) autoinjector devices. The available therapeutic options can be divided into pharmacologic and nonpharmacologic categories. The most common pharmacologic options described in the literature include phentolamine, subcutaneous terbutaline, topical nitrates, and calcium channel blockers. Nonpharmacologic options include observation and/or warm water soaks. Treatment recommendations in our proposed algorithm were based solely on the available data that we describe in our review. Conclusions: The literature did not provide clear guidance on the most appropriate management of accidental epinephrine injection. However, if pharmacologic therapy is necessary, phentolamine appears to be considered the most effective. Guidelines may be helpful in improving the management of accidental epinephrine injection, as well as in preventing unnecessary therapy

Probable Etoposide Interaction with Echinacea

Echinacea is an herbal supplement commonly used as an immune system stimulant to prevent infections, such as the common cold or flu. Echinacea has been documented as a cyctochrome P450 (CYP) 3A4 inhibitor in vitro, but no formal studies have been conducted in humans. Etoposide is a cytotoxic, topoisomerase II inhibitor, chemotherapeutic agent used in the treatment of lung cancer. Etoposide is primarily metabolized by CYP 3A4. We report the first possible drug–herbal interaction between Echinacea and etoposide. A 61-year-old gentleman newly diagnosed with nonsmall cell lung cancer began concurrent chemoradiation with cisplatin and etoposide. He was admitted to the hospital on day 8 of his first cycle and found to be thrombocytopenic. His platelet count eventually reached a nadir of 16 × 103/L, requiring platelet transfusion support. Upon admission, it was discovered he was taking Echinacea, which was discontinued. He received his next cycle of chemotherapy without taking Echinacea. His platelet count decreased to a nadir of 44 × 103/L, but he did not require platelet transfusions. Echinacea likely contributed to this patient\u27s profound thrombocytopenia and should be avoided in patients receiving etoposide and possibly other chemotherapeutic drugs that are CYP 3A4 substrates

Opioids: A Review of Pharmacokinetics and Pharmacodynamics in Neonates, Infants, and Children

Pain management in the pediatric population is complex for many reasons. Mild pain is usually managed quite well with oral acetaminophen or ibuprofen. Situations involving more severe pain often require the use of an opioid, which may be administered by many different routes, depending on clinical necessity. Acute and chronic disease states, as well as the constantly changing maturational process, produce unique challenges at every level of pediatrics in dosing and management of all medications, especially with regard to high-risk opioids. Although there has been significant progress in the understanding of opioid pharmacokinetics and pharmacodynamics in neonates, infants, children, and adolescents, somewhat limited data exist from which necessary information, concerning the safe and effective use of these agents, may be drawn. The evidence here provided is intended to be helpful in directing the practitioner to patient-specific reasons for preferring one opioid over another. As our knowledge of opioids and their effects has grown, it has become clear that older medications like codeine and meperidine (pethidine) have very limited use in pediatrics. This review provides pharmacokinetic and pharmacodynamic evidence on the currently available opioids: morphine, fentanyl (and derivatives), codeine, meperidine, oxycodone, hydrocodone, hydromorphone, methadone, buprenorphine, butorphanol, nalbuphine, pentazocin, ketobemidone, tramadol, piritramide, naloxone and naltrexone. Morphine, being the most studied opioid analgesic, is the standard against which all others are compared. Pharmacokinetic parameters of morphine that have been found in neonates, i.e., higher volume of distribution, immature metabolic processes that develop at various rates, elimination that is variable based on age and weight, as well as treated and untreated disease processes, are an example of all opioids in the population discussed in this review. Outside the premature and neonatal population, the use of opioids in infants, children, and adolescents quickly begins to resemble the established values found in adults. As such, the concerns (risks) of these medications become comparable to those seen in adults
