Algorithms to guide ambulance clinicians in the management of emergencies in patients with implanted rotary left ventricular assist devices.

Advances in left ventricular assist device (LVAD) therapy have resulted in increasing numbers of adult LVAD recipients in the community. However, device failure, stroke, bleeding, LVAD thrombosis and systemic infection can be life-threatening emergencies. Currently, four LVAD systems are implanted in six UK transplant centres, each of which provides device-specific information to local emergency services.

Barriers to screening for hepatitis B virus infection in Asian Americans.

Background: Routine screening for hepatitis B virus (HBV) infection can identify individuals who need vaccination or treatment, as vaccination can prevent HBV infection. Although the overall prevalence of HBV infection in the United States is low (<1%), it is high (~10%) in Asian Americans. However, HBV screening rates in this population have been reported to be low.

Persistence and adherence to nucleos(t)ide analogue treatment for chronic hepatitis B.

Background & Aims: Long-term treatment with nucleos(t)ide analogues (NUCs) is associated with increasing rates of antiviral drug resistance. Medication adherence is important in preventing drug resistance. This study aimed to determine, first, the persistence rates and the adherence rates to NUCs in patients with chronic hepatitis B (CHB), and second, the factors associated with adherence.

Rewards and advancements for clinical pharmacists.

The American College of Clinical Pharmacy charged the Clinical Practice Affairs Committee to review and update the College's 1995 White Paper, "Rewards and Advancements for Clinical Pharmacy Practitioners." Because of the limited data on the present state of rewards and advancements for clinical pharmacists, an online survey of "front-line" clinical pharmacists and pharmacy managers was conducted (1126 total respondents, 14% response rate). The resulting White Paper discusses motivators and existing systems of rewards and advancements for clinical pharmacists, as well as perceived barriers to implementation of these systems.

Impact of an educational program on efficacy and adherence with a twice-daily lamivudine/zidovudine/abacavir regimen in underrepresented HIV-infected patients.

A 24-week open-label clinical trial was conducted in 195 HIV-infected adults commonly underrepresented in research (35% female, 71% African American, 21% Hispanic, and 20% injection drug users [IDUs]) to evaluate the effect of an HIV educational program on efficacy and adherence with a simple, compact, twice-daily triple nucleoside regimen containing a lamivudine (150 mg)/zidovudine (300 mg) combination (COM) tablet plus abacavir (ABC), 300 mg. At baseline, the patients' median plasma HIV-1 RNA level was 4.18 log10 copies/mL and the median CD4+ cell count was 379 cells/mm3.

Compact quadruple therapy with the lamivudine/zidovudine combination tablet plus abacavir and efavirenz, followed by the lamivudine/zidovudine/abacavir triple nucleoside tablet plus efavirenz in treatment-naïve HIV-infected adults.

Purpose: To assess efficacy, safety, and adherence with compact quadruple therapy comprising one lamivudine 150-mg/zidovudine 300-mg tablet (COM) twice daily + one abacavir (ABC) 300-mg tablet twice daily + three efavirenz (EFV) 200-mg capsules at bedtime for 24 weeks, followed by one lamivudine 150-mg/zidovudine 300-mg/ABC 300-mg triple nucleoside tablet (TZV) twice daily + three EFV 200-mg capsules at bedtime for 24 weeks.

Method: A pilot 48-week, prospective, open-label trial in which 38 antiretroviral-naïve HIV-infected adults (baseline median HIV-1 RNA 5.1 log(10) copies/mL, CD4+ cell count 285/microL) received the above treatment and were monitored regularly with respect to plasma HIV-1 RNA levels, CD4+ cell counts, T-cell receptor excision circles (TRECs), adherence, and adverse events.

The changing face of Canadian home parenteral therapy.

This article describes the Calgary Health Region Home Parenteral Therapy Program (HPTP), which has successfully shifted infusion therapies such as anti-infectives, analgesics, hydration, vasodilators, glucocorticoids, and iron-chelating agents from the hospital to patients' homes. Particular attention is given to the parenteral administration of anti-infectives, which currently accounts for more than 95% of program adult therapy days.

Lamivudine 300 mg QD versus continued lamivudine 150 mg BID with stavudine and a protease inhibitor in suppressed patients.

Purpose: To compare the efficacy (sustained virologic suppression) and safety/tolerability of a switch to lamivudine 300 mg once daily (QD) versus continued lamivudine 150 mg twice daily (BID) in virologically suppressed patients (HIV-1 RNA <400 copies/mL for > or =3 months) on stable (> or =6 months) therapy with lamivudine 150 mg BID plus stavudine and either indinavir or nelfinavir.

Method: Eighty-nine suppressed patients > or =18 years old with CD4 counts >50 cells/mm(3) were enrolled in this phase II, open-label, multicenter, randomized, stratified (by pretrial protease inhibitor [PI]), parallel-group clinical trial. Eighty-one patients received either lamivudine 300 mg QD (n = 39) or 150 mg BID (n = 42) with their pretrial stavudine/PI regimens for 24 weeks.

Outpatient parenteral antibiotic therapy: evolution of the Calgary adult home parenteral therapy program.

In the past 25 years, outpatient antibiotic therapy has been recognized as a cost-effective, safe and patient-accepted means of managing patients with chronic infections who require prolonged parenteral therapy but otherwise do not need admission to hospital. We describe the home parenteral therapy program in Calgary, which reflects the next generation of outpatient antibiotic therapy in Canada because of its unique inclusion of patients with acute infections. The Calgary home parenteral therapy program has evolved from a few, small, single-site programs to a multisite, region-wide program that each year treats thousands of patients who require long- and short-term parenteral therapy.

Once-daily quadruple-drug therapy with adefovir dipivoxil, Lamivudine, Didanosine, and efavirenz in treatment-naive human immunodeficiency virus type 1-infected patients.

A 48-week open-label study of 11 antiretroviral-naive, human immunodeficiency virus type 1 (HIV-1)-infected adults evaluated once-daily treatment with adefovir dipivoxil, lamivudine, didanosine, and efavirenz. At baseline, the median plasma HIV-1 RNA level was 4.99 log(10) copies/mL, and the median CD4 cell count was 471 cells/mm(3).

Prospective, intensive study of metabolic changes associated with 48 weeks of amprenavir-based antiretroviral therapy.

To determine whether a 48-week course of amprenavir-based antiretroviral therapy is associated with metabolic alterations, 14 clinically stable human immunodeficiency virus (HIV)-infected, protease inhibitor-naive adults initiated amprenavir-based triple therapy. Twelve subjects (86%) achieved HIV RNA levels of <400 copies/mL at week 24. Fasting glucose and insulin levels did not change.
