Safety and efficacy of an 8-week regimen of grazoprevir plus ruzasvir plus uprifosbuvir compared with grazoprevir plus elbasvir plus uprifosbuvir in participants without cirrhosis infected with hepatitis C virus genotypes 1, 2, or 3 (C-CREST-1 and C-CREST-2, part A): two randomised, phase 2, open-label trials.

BACKGROUND: New hepatitis C virus (HCV) therapies with pan-genotypic efficacy are needed. The goals of part A of C-CREST-1 and C-CREST-2 were to compare the efficacies of two doses (300 mg or 450 mg once daily) of uprifosbuvir (MK-3682; NS5B inhibitor) in an 8-week regimen combined with grazoprevir (NS3/4A inhibitor; 100 mg once daily) and an NS5A inhibitor, either elbasvir (50 mg once daily) or ruzasvir (MK-8408; 60 mg once daily), and to evaluate the safety and tolerability of these combination regimens in individuals infected with genotypes 1, 2, or 3. METHODS: Part A of these phase 2, randomised, multicentre, open-label, clinical trials enrolled participants from 11 countries, aged 18 years or older, chronically infected with HCV genotypes 1, 2, or 3, with HCV RNA of at least 10 000 IU/mL, without evidence of cirrhosis, who had not received previous treatment for HCV infection. Within each HCV genotype, participants were randomly assigned (1:1:1:1) with a block size of 4, to open-label treatment to one of four treatment groups: grazoprevir (100 mg/day) plus ruzasvir (60 mg/day) plus uprifosbuvir (300 mg/day); grazoprevir (100 mg/day) plus ruzasvir (60 mg/day) plus uprifosbuvir (450 mg/day); grazoprevir (100 mg/day) plus elbasvir (50 mg/day) plus uprifosbuvir (300 mg/day); or grazoprevir (100 mg/day) plus elbasvir (50 mg/day) plus uprifosbuvir (450 mg/day), according to a computer-generated allocation schedule. Randomisation was centrally implemented using an interactive voice response system and integrated web response system. The primary endpoint was the proportion of participants achieving sustained virological response at 12 weeks (SVR12; HCV RNA less than the lower limit of quantitation at 12 weeks after the end of all study therapy) in the per-protocol analysis set, which included all participants who were randomised and received at least one dose of study drug. The trials are registered with ClinicalTrials.gov, numbers NCT02332707 and NCT02332720. FINDINGS: 241 participants were randomised between Feb 18, 2015, and March 16, 2015. 240 participants completed 8 weeks of treatment and reached follow-up 12 weeks after the end of treatment. Of the four regimens, grazoprevir plus ruzasvir plus uprifosbuvir 450 mg had the most consistently high SVR12 (>90%) for participants infected with genotype 1 (21 [91%] of 23), genotype 2 (15 [94%] of 16), and genotype 3 (20 [91%] of 22). In particular, among those with genotype 2 infection, the grazoprevir plus ruzasvir plus uprifosbuvir 450 mg regimen had a higher SVR12 (15 [94%] of 16) than the grazoprevir plus ruzasvir plus uprifosbuvir 300 mg regimen (ten [71%] of 14), grazoprevir plus elbasvir plus uprifosbuvir 300 mg regimen (11 [69%] of 16), or grazoprevir plus elbasvir plus uprifosbuvir 450 mg regimen (nine [60%] of 15). Overall, the most common adverse events were headache (55 [23%] of 240), fatigue (47 [20%] of 240), and nausea (32 [13%] of 240). Two (<1%) of 240 participants had serious adverse events (pharyngeal abscess and keratitis), which were not considered drug related by the respective investigators. INTERPRETATION: These results support further evaluation of the three-drug direct-acting antiviral agent regimen of grazoprevir 100 mg plus ruzasvir 60 mg plus uprifosbuvir 450 mg among a more diverse HCV-infected population, including those with compensated cirrhosis, previous treatment with an interferon-containing regimen, and HCV-HIV co-infection.

[Teaching patient-centered holistic care].

Nursing education aims to help students understand concepts and gain competencies in holistic care. The purpose of this paper was to present a nursing curriculum that adapted and introduced holistic care into an adult nursing curriculum taught at a university of science and technology. The course framework included both holistic and nursing domains. The holistic aspect addressed client physical psychological-spiritual needs and related factors, health related factors, and the status of Maslow's hierarchy of needs and related factors. The nursing aspect addressed the way in which nursing was applied to identify client problems and provide individualized, integrated and continuous care in hospital, family or community based settings employing primary, secondary, or tertiary prevention. Scenario with problem based learning and concept mapping were used in class to guide students to consider in depth the concepts that underpin holistic care.

Economic evaluation of bivalirudin with provisional glycoprotein IIB/IIIA inhibition versus heparin with routine glycoprotein IIB/IIIA inhibition for percutaneous coronary intervention: results from the REPLACE-2 trial.

OBJECTIVES: The purpose of this study was to compare the cost of percutaneous coronary intervention (PCI) using bivalirudin with provisional platelet glycoprotein (GP) IIb/IIIa inhibition with that of heparin + routine GP IIb/IIIa inhibition. BACKGROUND: Although GP IIb/IIIa inhibition has been shown to reduce ischemic complications in a broad range of patients undergoing PCI, many patients currently do not receive such therapy because of concerns about bleeding complications or cost. Recently, bivalirudin with provisional GP IIb/IIIa inhibition has been validated as an alternative to heparin + routine GP IIb/IIIa inhibition for patients undergoing PCI. However, the cost-effectiveness of this novel strategy is unknown. METHODS: In the Randomized Evaluation in PCI Linking Angiomax to Reduced Clinical Events (REPLACE)-2 trial, 4,651 U.S. patients undergoing non-emergent PCI were randomized to receive bivalirudin with provisional GP IIb/IIIa (n = 2,319) versus heparin + routine GP IIb/IIIa (n = 2,332). Resource utilization data were collected prospectively through 30-day follow-up on all U.S. patients. Medical care costs were estimated using standard methods including bottom-up accounting (for procedural costs), the Medicare fee schedule (for physician services), hospital billing data (for 2,821 of 4,862 admissions), and regression-based approaches for the remaining hospitalizations. RESULTS: Among the bivalirudin group, 7.7% required provisional GP IIb/IIIa. Thirty-day ischemic outcomes including death or myocardial infarction were similar for the bivalirudin and GP IIb/IIIa groups, but bivalirudin resulted in lower rates of major bleeding (2.8% vs. 4.5%, p = 0.002) and minor bleeding (15.1% vs. 28.1%, p < 0.001). Compared with routine GP IIb/IIIa, in-hospital and 30-day costs were reduced by $405 (95% confidence interval [CI] $37 to $773) and $374 (95% CI $61 to $688) per patient with bivalirudin (p < 0.001 for both). Regression modeling demonstrated that, in addition to the costs of the anticoagulants themselves, hospital savings were due primarily to reductions in major bleeding (cost savings = $107/patient), minor bleeding ($52/patient), and thrombocytopenia ($47/patient). CONCLUSIONS: Compared with heparin + routine GP IIb/IIIa inhibition, bivalirudin + provisional GP IIb/IIIa inhibition resulted in similar acute ischemic events and cost savings of $375 to $400/patient depending on the analytic perspective.
