An innovative chemical strategy named peptide welding technology (PWT) has been developed for the facile synthesis of tetrabranched peptides. [Dmt(1)]N/OFQ(1-13)-NH2 acts as a universal agonist for nociceptin/orphanin FQ (N/OFQ) and classical opioid receptors. The present study investigated the pharmacological profile of the PWT derivative of [Dmt(1)]N/OFQ(1-13)NH2 (PWT2-[Dmt(1)]) in several assays in vitro and in vivo after spinal administration in monkeys subjected to the tail withdrawal assay. PWT2-[Dmt(1)] mimicked the effects of [Dmt(1)]N/OFQ(1-13)-NH2 displaying full agonist activity, similar affinity/potency and selectivity at human recombinant N/OFQ (NOP) and opioid receptors in receptor binding, stimulation of [(35)S]GTPγS binding, calcium mobilization in cells expressing chimeric G proteins, and BRET studies for measuring receptor/G-protein and receptor/β-arrestin 2 interaction...

With a global prevalence of ~9%-12%, low back pain (LBP) is a serious public health issue, associated with high costs for treatment and lost productivity. Chronic LBP (cLBP) involves central sensitization, a neuropathic pain component, and may induce maladaptive coping strategies and depression. Treating cLBP is challenging, and current treatment options are not fully satisfactory. A new BioErodible MucoAdhesive (BEMA(®)) delivery system for buprenorphine has been developed to treat cLBP. The buccal buprenorphine (BBUP) film developed for this product (Belbuca™) allows for rapid delivery and titration over a greater range of doses than was previously available with transdermal buprenorphine systems...

As the polio endgame progresses, the world will increasingly rely on inactivated polio vaccine (IPV) for protection against polio (wild and vaccine-related) and for risk mitigation during the phased removal of oral polio vaccine (OPV). IPV has already been introduced in most countries and strategies are underway to ensure the remaining OPV-only using countries succeed in introducing IPV in light of operational challenges. Questions remain as to the ideal dosing schedule for IPV in developing countries as well as the length of time for IPV to be administered beyond certification of eradication of wild polioviruses and total OPV withdrawal...

The Global Polio Eradication Initiative (GPEI) has seen significant progress since it began in 1988, largely due to the worldwide use of oral poliovirus vaccine (OPV). In order to achieve polio eradication the global cessation of OPV is necessary because OPV contains live attenuated poliovirus, which in rare circumstances could re-gain wild poliovirus (WPV) characteristics with potential to establish transmission. The GPEI endgame strategy for the period 2013-2018 recommends the globally synchronised sequential cessation of the Sabin strains contained in the OPV, starting with type 2 Sabin...

Extracorporeal membrane oxygenation (ECMO) is temporary life-support technology that provides time to rest the cardiac and respiratory system of critically ill people with acute, reversible medical conditions. Health care providers face emotional and challenging situations, where death may result, when withdrawing ECMO. A deepening of understanding of the ethical issues involved can aid clinicians in handling such difficult situations, leading to a possible mitigation of the moral problems. Toward this end, the ethical issues raised in the consideration of ECMO withdrawal are analyzed with respect to the ethical principles and concepts of autonomy, nonmaleficence/beneficence, medical futility, moral distress, and justice...

Drug-induced liver injury (DILI) is a major cause of late-stage clinical drug attrition, market withdrawal, black-box warnings, and acute liver failure. Consequently, it has been an area of focus for toxicologists and clinicians for several decades. In spite of considerable efforts, limited improvements in DILI prediction have been made and efforts to improve existing preclinical models or develop new test systems remain a high priority. While prediction of intrinsic DILI has improved, identifying compounds with a risk for idiosyncratic DILI (iDILI) remains extremely challenging because of the lack of a clear mechanistic understanding and the multifactorial pathogenesis of idiosyncratic drug reactions...

BACKGROUND: Understanding children's health after a sibling's death and what factors may affect it is important for treatment and clinical care. This study compared children's and their parents' perceptions of children's health and identified relationships of children's age, gender, race/ethnicity, anxiety, and depression and sibling's cause of death to these perceptions at 2 and 4 months after sibling death. METHODS: 64 children and 48 parents rated the child's health "now" and "now vs before" the sibling's death in an ICU or ER or at home shortly after withdrawal of life-prolonging technology...

This paper addresses an important breakthrough in the deployment of ultra-high adhesion strength microfluidic technologies to provide turbulence at harsh flow rate conditions. This paper is only, to our knowledge, the second reporting on the generation of high flow rate-assisted turbulence in microchannels. This flow solves a crucial bottleneck in microfluidics: the generation of high throughput homogeneous mixings. We focused on the fabrication of bulky polydimethylsiloxane (PDMS) microchips (without any interfaces) rather than the laborious surface modifications that were employed in the first reporting about turbulence-assisted microfluidics...

BACKGROUND: Outcomes of traditional mechanical support paradigms (extracorporeal membrane oxygenation, intraaortic balloon pump [IABP], and permanent left ventricular assist device [LVAD]) in acute decompensated heart failure have generally been suboptimal. Novel approaches, such as minimally invasive LVAD therapy (Impella 5.0 device), promise less invasive but equivalent hemodynamic support. However, it is yet unknown whether the outcomes with such devices support widespread acceptance of this new technology...

Despite being relatively rare, drug-induced liver injury (DILI) is a serious condition, both for the individual patient due to the risk of acute liver failure, and for the drug development industry and regulatory agencies due to associations with drug development attritions, black box warnings, and postmarketing withdrawals. A major limitation in DILI diagnosis and prediction is the current lack of specific biomarkers. Despite refined usage of traditional liver biomarkers in DILI, reliable disease outcome predictions are still difficult to make...

INTRODUCTION: The introduction of recombinant human erythropoietin revolutionized the management of anemia in patients with chronic kidney disease (CKD). In order to circumvent costly recombinant DNA technology, synthetic chemistry techniques were used to manufacture peginesatide, a synthetic peptide that bore no resemblance to previous erythropoiesis-stimulating agents (ESAs), and yet was capable of stimulating erythropoiesis. Compared with other ESAs, peginesatide was deemed to have advantages related to immunogenicity, administration schedule, and cost...

BACKGROUND: The increasing prevalence and associated cost of treating Chronic Obstructive Pulmonary Disease (COPD) is unsustainable, and focus is needed on self-management and prevention of hospital admissions. Telehealth monitoring of patients' vital signs allows clinicians to prioritise their workload and enables patients to take more responsibility for their health. This paper reports the results of a qualitative study embedded within a feasibility and pilot Randomised Controlled Trial (RCT) of Telehealth-supported care within a community-based COPD supported-discharge service...

BACKGROUND AND AIM: Adenoma detection rate (ADR) is the most important quality indicator for screening colonoscopy, due to its association with colorectal cancer outcomes. As a result, a number of techniques and technologies have been proposed that have the potential to improve ADR. The aim of this study was to assess the potential impact of new-generation high-definition (HD) colonoscopy on ADR within the Bowel Cancer Screening Programme (BCSP). METHOD: This was a retrospective single-center observational study in patients undergoing an index screening colonoscopy...

New technologies like large-scale social media sites (e.g., Facebook and Twitter) and crowdsourcing services (e.g., Amazon Mechanical Turk, Crowdflower, Clickworker) are impacting social science research and providing many new and interesting avenues for research. The use of these new technologies for research has not been without challenges, and a recently published psychological study on Facebook has led to a widespread discussion of the ethics of conducting large-scale experiments online. Surprisingly little has been said about the ethics of conducting research using commercial crowdsourcing marketplaces...

Inefficient translational processes for technology-oriented biomedical research have led to some prominent and frequent failures in the development of many leading drug candidates, several designated investigational drugs, and some medical devices, as well as documented patient harm and postmarket product withdrawals. Derisking this process, particularly in the early stages, should increase translational efficiency and streamline resource utilization, especially in an academic setting. In this opinion article, we identify a 12-step guideline for reducing risks typically associated with translating medical technologies as they move toward prototypes, preclinical proof of concept, and possible clinical testing...

BACKGROUND: Smoking remains the leading cause of preventable disease and death in the United States. Therefore, researchers are constantly exploring new ways to promote smoking cessation. Mobile health (mHealth) technologies could be effective cessation tools. Despite the availability of commercial quit-smoking apps, little research to date has examined smokers' preferred treatment intervention components (ie, design features). Honoring these preferences is important for designing programs that are appealing to smokers and may be more likely to be adopted and used...
