Purpose
New therapies, including daratumumab plus lenalidomide plus dexamethasone (DRd) and daratumumab plus bortezomib plus dexamethasone (DVd), have recently been approved in the United States for patients with multiple myeloma (MM) who have received at least 1 prior line of therapy. However, few treatments have been compared in head-to-head clinical trials to determine the most efficacious therapy. In an update of the POLLUX (Phase 3 Study Comparing DRd Versus Rd in Subjects with Relapsed or Refractory Multiple Myeloma [RRMM]) trial, median progression-free survival (PFS) for DRd was not reached; the hazard ratio compared with Rd was 0.41. In an update of the CASTOR (Phase 3 Study Comparing DVd Versus Vd in Subjects with RRMM) trial, median PFS for DVd was 16.7 months, compared with 7.1 months for Vd with a PFS hazard ratio of 0.31. A systematic literature review and network meta-analysis (NMA) was performed to estimate the relative efficacy of treatments for previously treated patients with MM.Methods
A systematic search of MEDLINE, EMBASE, BioSciences Information Service, and the Cochrane Library databases was conducted from initiation to September 2016. Abstracts published by international congresses (2014–2016) and bibliographies of pertinent systematic reviews and meta-analyses were also searched. Eligible studies consisted of randomized controlled trials (RCTs) or long-term follow-up studies with >1 treatment arm assessing the efficacy or safety of MM therapies. An NMA was conducted by using Bayesian fixed effect mixed-treatment comparisons. Outcomes considered were hazard ratios for PFS and odds ratios for overall response rate (ORR).Findings
In total, 108 articles reporting 27 RCTs were included in the NMA. Data formed 2 evidence networks: RCTs with DRd and RCTs with DVd. Primary analysis of PFS found that DRd and DVd had a higher probability of being the best treatments (probability, 0.997 and 0.999, respectively) and had the lowest risk of progression or death than other treatments approved by the US Food and Drug Administration for the treatment of MM. Results from sensitivity analyses using time to progression as a proxy for missing PFS data were consistent. DRd and DVd also showed improved ORR compared with other treatments. Subgroup analyses of PFS in patients treated with only 1 prior therapy were like the results of the primary analyses.Implications
This NMA provides comparative efficacy for MM treatments not studied in head-to-head RCTs. The NMA suggests that, compared with other approved MM treatments in the United States, DRd and DVd have a higher probability of providing the longest PFS in patients who have received at least 1 prior therapy and in patients who have received only 1 prior therapy. 相似文献2.

PurposeAdding daratumumab to a regimen of bortezomib + dexamethasone (Vd) has been reported to provide a benefit of longer progression-free survival in patients with relapsed or refractory multiple myeloma (RRMM). However, it is still unclear whether the addition of daratumumab is cost-effective in RRMM. Based on the latest updated analysis of data from the CASTOR trial, this study performed an economic evaluation of the addition of daratumumab to Vd in patients with RRMM.MethodsA Markov decision model was used for estimating the long-term costs and efficacy of Vd with or without daratumumab in patients with RRMM. Data on efficacy were taken from the CASTOR trial to compare Vd + daratumumab with Vd. Costs were taken from the US Centers for Medicare & Medicaid Services and from the literature. A series of sensitivity analyses were performed to address the robustness of the model. Variations in the price of daratumumab and subgroup analyses were conducted.FindingsThe base-case analysis showed that adding daratumumab to Vd provided an additional 1.256 quality-adjusted life-years (QALYs) or 1.645 life-years (LYs), with incremental 213,164 USD (163,184 USD) per QALY (LY) gained. Univariate sensitivity analyses suggested that the subsequent treatment cost of DVd and the price of daratumumab had the greatest effect on the incremental cost-effectiveness ratio. According to the variations analysis of the price of daratumumab, the addition of daratumumab would be cost-effective when daratumumab was priced at 70% (30%) of the current price at a willingness-to-pay threshold of 200,000 USD/QALY (150,000 USD/QALY). Subgroup analysis indicated that adding daratumumab to Vd was most cost-effective in patients with 1 prior line of therapy.ImplicationsFrom a US-payer perspective, daratumumab added to Vd in RRMM is likely to exceed the common accepted values of cost-effectiveness 相似文献

Background
Advanced Practice Registered Nurses (APRNs) provide access to cost-effective, high quality care. APRNs are underutilized in states that restrict their practice. Removing restrictions could expand access to quality health care, cost-effectively relieve the physician shortage, and contribute economically.Purpose
This study forecasts the health system and economic impacts of reducing practice restrictions for Florida APRNs.Methods
The analysis utilized a number of data sources and IMPLAN software and estimated changes in APRN supply given less restrictive practice laws, and consequential health system and economic benefits.Findings
Between 2013 and 2025 APRN full time equivalents could increase an additional 11% with less restrictive practice regulations. This could eliminate or reduce the shortage of different types of physicians. Health care cost-savings could be $50 to $493 per resident. There would be a number of general economic benefits.Discussion
A number of health system and economic benefits would ensue from less restrictive APRN regulation. 相似文献4.

PurposeDaratumumab is a standard-of-care treatment for newly diagnosed multiple myeloma (NDMM). According to the ALCYONE trial, the addition of daratumumab to bortezomib, melphalan, and prednisone (D-VMP) provides significantly longer overall survival and progression-free survival than bortezomib, melphalan, and prednisone (VMP) in patients with NDMM. However, considering the high price of daratumumab, it is necessary to conduct further research on its efficacy and cost. This study evaluated the cost-effectiveness, from the US payer perspective, of D-VMP vs VMP in the first-line setting for patients with NDMM who are not eligible for autologous stem cell transplantation.MethodsA Markov model was developed to estimate the lifetime cost and effectiveness of VMP with or without daratumumab as the first-line therapy for patients with NDMM. Univariable sensitivity analysis and probabilistic sensitivity analysis were performed to address the model robustness and uncertainty. Expected value of perfect information analysis was conducted to explore the uncertainty of decision-making and future costs.FindingsD-VMP provides an additional 2.417 quality-adjusted life years (QALYs), at a cost of $30,893 per QALY. Sensitivity analysis revealed that the transition probability of progression-free survival in D-VMP strategy, the price of daratumumab, and body weight of the patient influenced the model results most strongly. Probabilistic sensitivity analysis showed that D-VMP versus VMP has a 90.8% probability of being cost-effective at the $150,000/QALY willingness-to-pay (WTP) threshold. The population expected value of perfect information was $2150 million at a WTP threshold of $50,000/QALY and $1481 million at $100,000/QALY.ImplicationsIn this study, D-VMP was estimated to be cost-effective compared with VMP for patients with NDMM at a WTP threshold of $150,000/QALY. 相似文献

Purpose
This commentary discusses the therapeutic and economic potentials of regenerative medicine (RM) by addressing how the reprioritization of resources in drug development may alleviate unmet medical need across many diseases, but especially cardiovascular diseases (CVDs) and musculoskeletal diseases (MSDs), the leading causes of mortality and morbidity, respectively, in the United States.Methods
Data and perspectives represented in this commentary were obtained through an online literature search, public press releases from federal agencies and companies, online opinion pieces, published journal articles, and consulting agency reports; however, there were limitations to the available data because of the breadth and novelty of the therapeutic modalities involved.Findings
Currently, the misallocation of resources within the therapeutic areas of CVDs and MSDs are possibly contributing to low approval rates, high cost of drug treatments, and consequently, disease burden. With a 2025 global market estimate of US $50.5 billion, RM is expected to become a major player in the pharmaceutical industry, with a potential to change the treatment paradigm and lessen disease burden across multiple disease areas, most notably in CVDs and MSDs.Implications
While the public sector appears to be doing its fair share by funding basic research and revamping regulatory regimes to address the vagaries of RM as a rapidly emerging novel technology, the support framework necessary for transforming the field from a promising concept to available therapy requires levels of resource allocation and marketing support that only the private sector can provide. 相似文献6.
Purpose
Hepatitis C, a chronic disease with deadly consequences, is no longer predominantly a disease of older people.Methods
A limited search was conducted of the relevant literature on 2 topics: (1) the impact of hepatitis C on infants exposed by vertical transmission; and (2) the impact of hepatitis C infection on infected children and adolescents. The findings were supplemented by the first-hand experience of the authors.Findings
Young people, including women of childbearing age, infants, children, and adolescents, are being especially affected by hepatitis C infection secondary to the intravenous drug use and opioid epidemic. Unfortunately, estimates of disease in young populations are all misleading because universal screening has not been implemented.Implications
Lack of implementation of policies for screening and therapy on most affected populations will be responsible for perpetuation of this infection. In the era of highly effective therapy and a regimen that is approved by the US Food and Drug Administration for children, this outcome is unacceptable. 相似文献7.

Purpose
Several antihypertensive medications have been associated with various forms of sexual dysfunction. We present a case report of a premenopausal patient with hydralazine-associated amenorrhea.Methods
The Naranjo adverse drug reaction probability scale was used to assess causality. We also performed a literature search on PubMed to find publications that report hydralazine-associated amenorrhea.Results
The Naranjo scale generated a score of 6, suggesting a probable relationship between amenorrhea and hydralazine therapy. No publications associating hydralazine with amenorrhea were identified.Implications
A probable relationship exists between hydralazine and the development of amenorrhea. 相似文献8.

Background
Pragmatic dissemination and implementation (D&I) research approaches can benefit patient care because they emphasize real-world settings and populations. Nurse scientists have an opportunity to reduce the gap between science and practice by using pragmatic D&I research and sustainability strategies.Purpose
This article discusses pragmatic models, methods, and measures used in D&I research and their relevance for nursing research and enhancing population health.Methods
Summary of pragmatic D&I models and related methods for designing a pragmatic studies. We discuss the RE-AIM framework and the PRECIS-2 planning aid and figure in detail. A case study is provided and application to nursing research is discussed.Discussion
Successful translation of pragmatic D&I research demands an approach that addresses external validity, and customization at multiple levels including the patient, clinician, and setting. Context is critically important, and it is never too early to design for dissemination.Conclusions
Pragmatic D&I approaches are needed to speed research translation, reduce avoidable waste of funding, improve clinical care, and enhance population health. Pragmatic D&I research is an area of tremendous opportunity for the nursing science community. 相似文献10.
Purpose
Respiratory syncytial virus (RSV) and influenza are important viral pathogens worldwide. Children, in particular, bear considerable burdens of morbidity and mortality associated with these viruses. There are limited therapeutic options for children infected with RSV or influenza. This review focuses on therapeutics for RSV and influenza that are currently under clinical investigation.Methods
This study used a systematic approach to identify prospective therapeutics in clinical trials and briefly reviewed those that are currently available for use in adults and children.Findings
Overall, we found 14 investigational drugs currently in clinical trials for RSV and 20 investigation drugs currently in clinical trials for influenza. These candidates range in development from Phase I to Phase III clinical trials.Implications
Both RSV and influenza are targets for active therapeutic research, and promising candidates for both viruses are currently in clinical development. 相似文献11.
Background
Nurses are among the many U.S. health professionals engaged in international learning or service experiences and often travel to low-resource countries lacking guidance for ethical practice, respect for host partners, or collaborative work in different health systems.Purpose
The aim of this study is to develop evidence-based principles or guidelines for ethical global health nursing practice.Methods
A three-round Delphi study was conducted. Global health nurse experts participated in Round 1 focus group, followed by nurses with global health expertise ranking global health nursing statements in Rounds 2 and 3.Discussion
Findings led to 10 Ethical Principles for Global Health Nursing Practice and 30 statements for Ethical Guidelines in Global Health Nursing. These Ten principles address beneficence, nonmaleficence, dignity, respect, autonomy, social justice, and professional practice. The 30 guidelines offer more specific actions nurses must consider when working in global settings. 相似文献12.

Purpose
This review article focuses on preventing vertical transmission of hepatitis B virus (HBV) among pregnant women living in sub-Saharan Africa (SSA), where disease is endemic and the estimated maternal HBV seroprevalence is >8%. Available interventions that have been studied in low- and middle-income countries are compared in terms of efficacy and effectiveness in clinical practice. Global disease-elimination targets, barriers to HBV-prevention efforts, and critical research gaps are discussed.Methods
A PubMed literature search in February 2018 identified relevant studies of interventions to reduce or prevent the transmission of HBV during pregnancy or in the peripartum period. Studies that focused on interventions that are currently available or could be made available in SSA were included. Trials conducted in SSA and other low-income countries were prioritized, although studies of interventions in middle- and high-income countries were included.Findings
Among 127 studies and reports included in the review, 60 included data from SSA. The most cost-effective intervention to reduce HBV infection rates in SSA is timely birth-dose vaccination followed by completion of the 3-dose infant-vaccination series. The identification and treatment of pregnant women with elevated HBV viral load to further reduce the risk for vertical transmission in SSA show promise, but efficacy and tolerability trials in Africa are lacking.Implications
Scale-up of currently available tools is required to reach HBV disease-elimination goals in SSA. Many countries in SSA are in the process of rolling out national birth-dose vaccination campaigns; this roll out provides an opportunity to evaluate and improve processes in order to expand coverage. Early antenatal care, promotion of facility deliveries, and increased awareness of HBV prevention are also key components of prevention success. Future studies in SSA should identity an HBV-prevention package that is effective, well tolerated, and feasible and can be administered in the antenatal clinic and tailored to vertical-transmission risk. 相似文献14.

Purpose
The purpose of this study was to investigate the safety, tolerability, and pharmacokinetic profile of sofosbuvir and its metabolites after a single dose of sofosbuvir 400mg and once daily dosing of sofosbuvir 400mg for 7days in healthy Chinese subjects.Methods
This Phase I, open-label, single- and multiple-dose study enrolled 14 Chinese subjects aged 18 to 45years with an approximately even distribution of healthy male (n?=?9) and nonpregnant, nonlactating female subjects (n?=?5). Subjects received a single oral dose of sofosbuvir 400mg (one tablet) (morning, fasted conditions; single-dose treatment). After a 3-day washout, subjects received oral sofosbuvir 400mg (one tablet) (morning, fasted) for 7days (multiple dose treatment).Findings
No significant accumulation of sofosbuvir, GS-566500, or GS-331007 was observed. Steady state of the major metabolite GS-331007 was achieved after 4days of consecutive dosing with sofosbuvir 400mg once daily. Sofosbuvir was generally well tolerated.Implications
Overall, this study supports the further evaluation of sofosbuvir 400mg in the Chinese population. The pharmacokinetic properties of sofosbuvir, GS-556500, and GS-311007 were found to be broadly similar in healthy Chinese subjects compared with non-Chinese subjects in previous sofosbuvir studies.

Purpose
The aim of this article was to describe and compare treatment patterns, health care resource utilization (HRU), and health care costs before and after transition in veterans with schizophrenia who were transitioned from paliperidone palmitate given once monthly (PP1M) to paliperidone palmitate given every 3 months (PP3M) according to prescribing-information guidelines.Methods
This retrospective, longitudinal study was conducted using electronic health records data from the Veterans Health Administration (VHA). Veterans were eligible for inclusion if they were aged 18years or older, had ≥1 dispensation of PP3M, were enrolled with VHA benefits for ≥24 months prior to transition to PP3M, had ≥1 schizophrenia diagnosis, were transitioned to PP3M according to prescribing-information guidelines (operationalized as no gap in PP1M treatment of >45days during the 4 months prior to PP3M transition, with the same dosage in the last 2 PP1M dispensations), and had appropriate dose conversion. Treatment patterns, HRU, and costs 6 months pre and post PP3M transition were described and compared using the McNemar test and the Wilcoxon signed rank test.Findings
Of the 277 veterans identified, the majority were men (92.8%); the median age was 56.5years. Among 197 veterans who had at least 6 months of follow-up pre and post PP3M transition, oral antipsychotic use was significantly decreased (from 49.7% to 43.1%; P?=?0.0326). Additionally, the mean number of days spent in an inpatient setting (41.4vs 21.6; P?=?0.0164), the mean number of outpatient visits per patient (31.0vs 25.6; P < 0.0001), and the mean total health care costs ($27,745vs $23,772; P?=?0.0050) were significantly decreased.Implications
After transitioning to PP3M treatment, veterans had significantly reduced use of oral antipsychotics, HRU, and costs. Although generalizability may be limited due to the veteran population and to those who transitioned according to PP3M prescribing guidelines, future studies in other patient populations may be used to extend these conclusions. 相似文献16.
Purpose
The objective of this review was to summarize the recent literature describing the current burden of disease due to herpesviruses in the antiviral and transplant era; describe mechanisms of action of antiviral agents and the development of resistance; summarize the literature of recent antiviral agents brought to market as well as agents under development; and to present literature on future strategies for herpesvirus therapeutics.Methods
An extensive search of the medical literature related to antiherpesviral therapy was conducted to compose this narrative review. Literature searches were performed via PubMed and ultimately 137 articles were included as most relevant to the scope of this article.Findings
Herpesviruses are a family of DNA viruses that are ubiquitous throughout human populations and share the feature of establishing lifelong infections in a latent phase with the potential of periodic reactivation. With the exception of herpes simplex virus, varicella zoster virus, and Epstein-Barr virus, which have a significant disease burden in individuals with normal immune function, the morbidity and mortality of the remaining viruses are primarily associated with the immunocompromised host. Over the last half-century, several agents have been tested in large randomized, placebo-controlled trials that have resulted in safe and effective antiviral agents for the treatment of many of these infections.Implications
With increasing use of antiherpesviral agents for extended periods, particularly in immunocompromised hosts, the emergence of resistant viruses has necessitated the development of newer agents with novel targets and better side-effect profiles. 相似文献17.

Purpose
Oxaliplatin-induced peripheral neuropathy has remained an unresolved issue in clinical practice. Our previous study hypothesized that inhibition of the renin-angiotensin system (RAS) may produce a preventive effect on oxaliplatin-induced neuropathy. The aim of this study was to clarify whether RAS inhibitors prevent oxaliplatin-induced peripheral neuropathy.Methods
This study retrospectively analyzed data from cancer patients who had received chemotherapy including oxaliplatin and were treated with or without RAS inhibitors. This retrospective observational study was conducted at Ehime University Hospital using electronic medical records from May 2009 to December 2016. The primary end point was the incidence of severe peripheral neuropathy during or after oxaliplatin treatment, according to the Common Terminology Criteria for Adverse Events, version 4.0. A multivariate Cox proportional hazards model analysis was used to identify risk factors.Findings
A total of 150 patients were included in the study. The estimated incidence of peripheral neuropathy was 36.9% and 91.7% in the RAS inhibitor group and the non–RAS inhibitor group, respectively. The multivariate analysis using a Cox proportional hazards model showed that the RAS inhibitor group was slightly associated with a decreased risk of neurotoxicity (adjusted hazard ratio, 0.42 [95% CI, 0.18–0.99]; P?=?0.048).Implications
The present findings suggest that RAS inhibitors have the ability to prevent oxaliplatin-induced peripheral neuropathy. 相似文献18.

Purpose
Pregabalin and thioctic acid are likely to be used concomitantly for the treatment of painful diabetic neuropathy. In this study, the pharmacokinetic interaction between pregabalin and thioctic acid was investigated at steady state.Methods
A randomized, open-label, 6-sequence, 3-period, 3-treatment crossover study was conducted in 42 healthy male volunteers. The volunteers randomly received pregabalin 300 mg BID for 6 times, thioctic acid 600 mg once daily for 3 times, or the combination of pregabalin and thioctic acid. Serial blood samples were collected up to 24 hours after the last dosing in each period. Pharmacokinetic parameters were calculated by using noncompartmental analysis methods.Findings
The mean concentration–time curves were similar between each drug alone and in combination with the other drug. The 90% CIs of the geometric mean ratios with and without the co-administered drug for Cmax at steady state and AUC during the dosing interval were well within the conventional bioequivalence range of 0.8 to 1.25, except for Cmax at steady state for thioctic acid, which barely exceeded only the lower bound (0.78–1.15). Co-administered pregabalin and thioctic acid was well tolerated.Implications
Repeatedly administered pregabalin and thioctic acid do not interact pharmacokinetically. This study suggests that the combination of pregabalin and thioctic acid can safely be administered concomitantly without dose adjustment. ClinicalTrials.gov identifier: NCT01808300. 相似文献19.

Purpose
Induction immunosuppression therapy is used to support optimal outcomes in kidney transplantation. This study was to assess the cost-effectiveness of rabbit antithymocyte globulin (r-ATG) versus ATG-Fresenius (ATG-F) in kidney transplantation in the Chinese setting from the perspective of the health care payer.Methods
A 2-part survival model was developed, consisting of a short-term part and a long-term part. The short-term part analyzed the first year, using the decision tree, and consisted of the functioning transplant, acute rejection (AR), delayed graft function (DGF), dialysis, and death health states. The long-term part analyzed 2 to 5 years, using Markov model, and consisted of the functioning transplant, chronic dysfunction, recurring primary disease, dialysis, and death health states, with capture of the association between DGF and graft loss. Costs, including drug acquisition and other direct medical costs, were derived from China IQVIA database (formerly known as IMS) hospitaldatabase, chart review, and physician interviews. Clinical outcomes and utility were retrieved from published literature. The model calculated quality-adjusted life-years (QALYs) and total costs per patient. Costs and QALYs were discounted at an annual rate of 3.5%. Univariate sensitivity analysis and probability sensitivity analysis (PSA) were conducted to assess the impact of uncertainty of the variables on the results.Findings
Patients who received r-ATG had more clinical effectiveness than patients who received ATG-F mainly because of less AR, DGF, and dialysis. The incremental QALY was 0.01 over a 1-year time horizon and 0.0496 over a 5-year time horizon. R-ATG and ATG-F drug costs were ¥10,783 and ¥8409, respectively. However, the total treatment costs of the r-ATG arm were lower than the ATG-F arm because of lower costs related to DGF, AR, dialysis, and adverse events. In total, r-ATG saved ¥5423 over the 1-year and ¥7042 over the 5-year time horizon. R-ATG was dominant with lower total direct medical costs and higher QALYs compared with ATG-F. Both univariate sensitivity analysis and PSA found the robustness of the model results. PSA results indicated that r-ATG was cost-effective compared with ATG-F in 86.81% of the simulations, considering <3 times the gross domestic product per capita as the threshold.Implications
From the perspective of the health care payer, r-ATG should be considered as the preferred treatment agent for induction therapy for Chinese patients undergoing kidney transplantation because of its lower overall medical costs and greater QALYs gained compared with ATG-F. The study was limited by lack of long-term efficacy data among the Chinese population and lack of comprehensive real-world higher quality costs data. 相似文献20.
