    Title Effect of Pioglitazone on Platelet Aggregation in a Healthy Cohort.
    Date February 2011
    Journal Cardiology

    Peroxisome proliferator-activated receptor (PPAR) agonists can favorably influence atheroma proliferation, lipoprotein metabolism and macrovascular complications. Pioglitazone, one of the thiazolidinedione compounds, is a PPAR ligand activator and a clinically important PPAR agonist. There is controversy in the literature about its potential antiplatelet effects. Its direct platelet inhibition is a novel hypothesis tested in animal models and in human populations with underlying diabetic and/or cardiovascular diseases. The present study was aimed to test the hypothesis of direct platelet aggregation inhibition with the use of pioglitazone in a healthy population.

    Title Prevalence of Antiretroviral Drug Resistance Among Treatment-naive and Treated Hiv-infected Patients in Venezuela.
    Date August 2009
    Journal Memórias Do Instituto Oswaldo Cruz

    An in-house, low-cost method was developed to determine the genotypic resistance of immunodeficiency virus type 1 (HIV-1) isolates. All 179 Venezuelan isolates analysed belonged to subtype B. Primary drug resistance mutations were found in 11% of 63 treatment-naïve patients. The prevalence of resistance in isolates from 116 HIV-positive patients under antiretroviral treatment was 47% to protease inhibitors, 65% to nucleoside inhibitors and 38% to non-nucleoside inhibitors, respectively. Around 50% of patients in the study harboured viruses with highly reduced susceptibility to the three classical types of drugs after only five years from their initial diagnoses.

    Title Potential in Vitro Interaction Between Tenecteplase and Unfractionated Heparin.
    Date December 2004
    Journal Pharmacotherapy

    STUDY OBJECTIVE: To explore the potential of a direct drug interaction between unfractionated heparin (UFH) and tenecteplase that lowers the pharmacologic propensity of UFH to prolong the activated partial thromboplastin time (aPTT). DESIGN: In vitro experiment. SETTING: Texas Tech University School of Pharmacy, with sample analysis performed at an independent, contract laboratory. Samples. Blood samples collected from healthy volunteers. INTERVENTION: Three separate in vitro experiments were conducted to explore the relative influence of various thrombolytic agents with and without UFH on aPTT prolongation. In each experiment, blood from healthy volunteers (12 for each experiment) was treated with different concentrations and combinations of tenecteplase and UFH. MEASUREMENTS AND MAIN RESULTS: When the effects of tenecteplase plus UFH versus UFH alone on aPTT prolongation were compared, each experiment demonstrated attenuation of aPTT with the combination versus UFH alone. In contrast, findings for other thrombolytic agents combined with UFH demonstrate elevation of the aPTT compared with UFH alone. CONCLUSION: The results indicate a possible drug interaction between tenecteplase and UFH, with tenecteplase attenuating the intensity of anticoagulation of UFH in vitro. Further investigation into this possible interaction is warranted in the clinical setting.

    Title Exploring the Effects of Ace Inhibitor Tissue Penetration on Vascular Inflammation Following Acute Myocardial Infarction.
    Date November 2004
    Journal Coronary Artery Disease

    BACKGROUND: Questions remain as to the existence of a class effect amongst angiotensin converting enzyme (ACE) inhibitors, and some literature suggests that pharmacological effects and outcomes may be determined by an ACE inhibitor's propensity to penetrate and inhibit the ACE enzyme at the vascular tissue level. Because vascular inflammation contributes to adverse outcomes following acute myocardial infarction (AMI), and angiotensin II influences inflammation at the vascular level, we hypothesized that high-tissue penetrating ACE inhibitors would provide more favorable effects on C-reactive protein (CRP) after AMI compared to low-tissue penetrating ACE inhibitors. METHODS AND RESULTS: In a randomized open-label trial, patients received the high-tissue penetrating quinapril (n = 15) or low-tissue penetrating enalapril (n = 15) following AMI. C-reactive protein was measured at baseline and periodically over 14 days following drug initiation. All baseline characteristics and blood pressure response to treatment between groups were equivalent. Prior to initiating study medication, CRP concentrations (mg/g) were similar between enalapril and quinapril (0.327 +/- 0.571 versus 0.273 +/- 0.380, respectively, p = 0.77). The percent magnitude of change in CRP concentrations favored quinapril at all time points, starting 12 h after treatment initiation. When characterizing CRP production during treatments, the time courses were significantly different and demonstrated lower CRP concentrations with quinapril (p = 0.0107). CONCLUSIONS: Overall, this investigation into the importance of ACE inhibitor tissue penetration on a common marker of vascular inflammation, suggests a potential vascular anti-inflammatory benefit with a more highly tissue penetrating ACE inhibitor following AMI. Further investigation into the true pharmacological similarities and differences amongst this class of drugs is warranted.

    Title Comparison of Effects of Quinapril Versus Enalapril on Vasoactive Substances Following Acute Myocardial Infarction.
    Date September 2004
    Journal The American Journal of Cardiology

    The true existence of a class effect in angiotensin-converting enzyme (ACE) inhibitors remains controversial. The present trial explored the effects of 2 ACE inhibitors after acute myocardial infarction and found no difference in endothelin-1 production but a greater increase in the production of total nitric oxide with quinapril than with enalapril.

    Title Review of Catheter Thrombectomy Devices.
    Date August 2004
    Journal Cardiology

    Acute massive pulmonary embolism (PE) is a frequently fatal event that causes significant compromise of hemodynamic stability. Unfortunately, mortality rates for PE have remained relatively constant despite advances in prophylactic and treatment measures. In addition to embolus size, symptom recognition for diagnosis and emergent treatment are two distinct factors that dictate survival. Treatment generally includes thrombolytic agents; however, not all patients are candidates for aggressive thrombolytic management. Development of catheter thrombectomy devices provides an alternative treatment modality for severe cases when thrombolytics are contraindicated. Catheter thrombectomy devices have undergone major advances over the last decade, but literature support of their success is limited.

    Title Questioning a Class Effect: Does Ace Inhibitor Tissue Penetration Influence the Degree of Fibrinolytic Balance Alteration Following an Acute Myocardial Infarction?
    Date July 2004
    Journal Journal of Clinical Pharmacology

    There is a common belief in a class effect among angiotensin-converting enzyme (ACE) inhibitors. This is unsubstantiated for acute myocardial infarction (AMI). Because vascular tissue is a source of the endogenous fibrinolytic markers, and ACE inhibition in vascular tissue favorably influences the fibrinolytic system, the authors hypothesized that a high-tissue-penetrating ACE inhibitor would provide a more favorable reduction in plasminogen activator inhibitor-1 (PAI-1) and an increase in tissue plasminogen activator (t-PA) after AMI compared to a low-tissue-penetrating ACE inhibitor. In a randomized open-label trial, patients received the high-tissue-penetrating quinapril (n = 15) or low-tissue-penetrating enalapril (n = 15) immediately following an AMI. PAI-1 and t-PA antigen (ng/mL) were measured at baseline and through 14 days of treatment. There was no difference in baseline PAI-1 or t-PA antigen between treatments. PAI-1 antigen trended toward being lower with quinapril versus enalapril on day 1 (24.44 +/- 14.96 vs. 36.94 +/- 19.49, respectively, p = 0.059) and was significantly lower on day 3 (17.32 +/- 9.57 vs. 27.49 +/- 9.61, respectively, p = 0.009). Analysis of PAI-1 antigen over time by two-factor ANOVA with replication found significantly lower concentrations of PAI-1 antigen over the entire treatment period with quinapril versus enalapril (p < 0.003). This investigation of ACE inhibitor tissue-penetrating influence on markers of reinfarction risk suggests there may be a greater early reduction in PAI-1 with a more highly tissue-penetrating ACE inhibitor.

    Title Plasminogen Activator Inhibitor-1: Physiologic Role, Regulation, and the Influence of Common Pharmacologic Agents.
    Date March 2003
    Journal Journal of Clinical Pharmacology

    Plasminogen activator inhibitor-1 (PAI-1) is the major inhibitor of endogenous thrombolysis, thereby promoting thrombosis. PAI-1 is also a primary contributor to the development and recurrence of acute myocardial infarction. The renin angiotensin system, hypertriglyceridemia, hyperglycemia and hyperinsulinemia, and estrogen all influence the fibrinolytic system and PAI-1 in particular. Available data strongly suggest that angiotensin-converting enzyme (ACE) inhibitors and hormone replacement therapy with estrogen beneficially reduce PAI-1 production. Metformin, an agent commonly used for non-insulin-dependent diabetes mellitus (NIDDM), appears to favorably decrease PAI-1 production in NIDDM patients but not nondiabetic patients. Among the cholesterol-lowering statins, clinical literature evaluating pravastatin provides the most compelling data to support this agent's favorable effect on PAI-1. Other available statins either have not displayed an effect on PAI-1 or do not have clear data to conclusively define their effects on the fibrinolytic system.

    Title An Outbreak of Typhoid Fever in Florida Associated with an Imported Frozen Fruit.
    Date August 2002
    Journal The Journal of Infectious Diseases

    An outbreak of typhoid fever in Florida involving at least 16 persons during the winter of 1998-99 was investigated using case-control, environmental, and laboratory methods. The genomic profiles of Salmonella serovar Typhi (Salmonella Typhi) isolates from the 15 confirmed case subjects were identical. Consumption of fruit shakes made with frozen mamey, a tropical fruit, was significantly associated with illness (matched odds ratio, 7.6; 95% confidence interval, 1.4-81.4). Laboratory testing showed that the fruit was heavily contaminated with fecal coliforms; no Salmonella Typhi was isolated. The frozen mamey was prepared in plants in Guatemala and Honduras. No further cases occurred after the frozen product was recalled. As our nation's food sources become increasingly globalized, the risk of outbreaks of exotic diseases linked to contaminated imported food will increase. This outbreak highlights the need for new approaches to ensure the safety of our food supply.

    Title An Assessment of the Ability of Routine Restaurant Inspections to Predict Food-borne Outbreaks in Miami-dade County, Florida.
    Date May 2001
    Journal American Journal of Public Health

    OBJECTIVES: This study sought to determine the usefulness of restaurant inspections in predicting food-borne outbreaks in Miami-Dade County, Fla. METHODS: Inspection reports of restaurants with outbreaks in 1995 (cases; n = 51) were compared with those of randomly selected restaurants that had no reported outbreaks (controls; n = 76). RESULTS: Cases and controls did not differ by overall inspection outcome or mean number of critical violations. Only 1 critical violation--evidence of vermin--was associated with outbreaks (odds ratio = 3.3; 95% confidence interval = 1.1, 13.1). CONCLUSIONS: Results of restaurant inspections in Miami-Dade County did not predict outbreaks. If these findings are representative of the situation in other jurisdictions, inspection practices may need to be updated.
