BACKGROUND: In patients with left ventricular heart failure (HF), the development of pulmonary hypertension (PH) is common and represents a strong predictor of death. Despite recent advances in the pathophysiological understanding there is as yet no prospect of cure of this deadly clinical entity and the majority of patients continue to progress to right ventricular failure and die. Furthermore, there is no single medical treatment currently approved for PH related to HF. There is, therefore an urgent unmet need to identify novel pharmacological agents that will prevent the progressive increased or reverse the elevated pulmonary arterial pressures while enhancing cardiac performance in HF...

Fully addressable DNA nanostructures, especially DNA origami, possess huge potential to serve as inherently biocompatible and versatile molecular platforms. However, their use as delivery vehicles in therapeutics is compromised by their low stability and poor transfection rates. This study shows that DNA origami can be coated by precisely defined one-to-one protein-dendron conjugates to tackle the aforementioned issues. The dendron part of the conjugate serves as a cationic binding domain that attaches to the negatively charged DNA origami surface via electrostatic interactions...

Developmental pathways (e.g., Notch, Hippo, Hedgehog, Wnt, and TGF-β/BMP/FGF) are networks of genes that act co-ordinately to establish the body plan, and disruptions of genes in one pathway can have effects in related pathways and may result in serious dysmorphogenesis or cancer. Interestingly, all developmental pathways are highly conserved cell signalling systems present in almost all multicellular organisms. In addition, they have a crucial role in cell proliferation, apoptosis, differentiation, and finally in organ development...

Median overall survival (OS) of patients with metastatic colorectal cancer (mCRC) has reached up to 30months in recent clinical trials of first line therapies. Following disease progression after the standard in both, 1st and 2nd line, combination chemotherapy with monoclonal antibodies, many patients maintain a good performance status and a significant proportion is motivated to undergo further therapy. Choices of treatment beyond the second line setting for mCRC are therefore becoming increasingly important...

In the European Union, slaughter without stunning is allowed for religious slaughter to obtain halal and kosher meat. Especially in the case of Jewish slaughtering, cuts which are not deemed as kosher are sold to regular market without any specific labelling. This survey, conducted in Tuscany in 2016, aimed to quantify the carcasses rejected in relation to the type of religious slaughter. 656 bovines were slaughtered without stunning: 538 (82%) for halal and 118 (18%) for kosher. All carcasses slaughtered by the Islamic procedure (dhabiha) were considered halal, while 77...

BACKGROUND: Although gambling disorder is prevalent and functionally impairing, no FDA-approved medications exist for its treatment. The ability of clinical trials to detect the benefits of active treatment has been hindered by an unusually high placebo response. Virtually nothing is known about baseline clinical characteristics that might predict placebo response in those with gambling disorder. METHODS: Participants (N = 152) assigned to placebo were pooled from multiple double-blind trials of gambling disorder...

INTRODUCTION: Fluorescence-guided surgery has emerged as a powerful tool to detect, localize and resect tumors in the operative setting. Our laboratory has pioneered a novel way to administer an FDA-approved near-infrared (NIR) contrast agent to help surgeons with this task. This technique, coined Second Window ICG, exploits the natural permeability of tumor vasculature and its poor clearance to deliver high doses of indocyanine green (ICG) to tumors. This technique differs substantially from established ICG video angiography techniques that visualize ICG within minutes of injection...

BACKGROUND: Although most biologic medications for patients with rheumatoid arthritis (RA) have recommended fixed dosing, actual biologic dosing may vary among real-world patients, since some patients can receive higher (high-dose outliers) or lower (low-dose outliers) doses than what is recommended in medication package inserts. OBJECTIVE: To describe the patterns of care for biologic-dosing outliers and nonoutliers in biologic-naive patients with RA. METHODS: This was a retrospective, longitudinal cohort study of patients with RA who were not pregnant and were aged ≥ 18 and < 90 years from an integrated health care delivery system...

BACKGROUND: With the rapid growth of specialty pharmacies, including those within academic health systems, pharmacists have the opportunity to improve patient care through the management of specialty medications. Specialty pharmacists within academic health systems are uniquely positioned to overcome restrictions to medication access, financial constraints, and provider burdens that often lead to obstacles for patients to start and maintain necessary treatments. The Vanderbilt Specialty Pharmacy (VSP) model at Vanderbilt University Medical Center (VUMC) provides an example of a patient-centered, collaborative care prototype that places pharmacists directly into specialty clinics to assist with comprehensive management of patients on specialty medications...

Integrase mutations can reduce effectiveness of the first-generation FDA-approved integrase strand transfer inhibitors (INSTIs), raltegravir (RAL) and elvitegravir (EVG). The second-generation agent, dolutegravir (DTG) has enjoyed considerable clinical success; however, resistance-causing mutations that diminish the efficacy of DTG have appeared. Our current findings support and extend the substrate envelope concept that broadly effective INSTIs can be designed by filling the envelope defined by the DNA substrates...

Memantine was the first breakthrough medication for the treatment of moderate to severe Alzheimer's disease (AD) patients, and represents a fundamentally new mechanism of action (moderate-affinity, uncompetitive, voltage-dependent, N-methyl-D-aspartate (NMDA) receptor antagonist that exhibits fast on/off kinetics) to modulate glutamatergic dysfunction. Since its approval by the FDA in 2003, memantine, alone, and in combination with donepezil, has improved patient outcomes in terms of cognition, behavioral disturbances, daily functioning and delaying time to institutionalization...

BACKGROUND: Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization (WHO) guidelines for pharmacological treatments for persisting pain in children acknowledge that pain in children is a major public health concern of high significance in most parts of the world. Views on children's pain have changed over time and relief of pain is now seen as important. In the past, pain was largely dismissed and was frequently left untreated, and it was assumed that children quickly forgot about painful experiences...

The nusinersen development and approval process provide important lessons regarding the pathway to marketing approval for gene therapies. These lessons emphasize rigorous clinical trial design, flexibility in trial design and analysis, a collaborative effort with regular communications between the drug developer and the FDA, and use of FDA's expedited programs. These lessons are critical to the development of gene therapies for the treatment of serious or life-threatening rare diseases.Gene Therapy accepted article preview online, 24 July 2017...

Pulmonary arterial hypertension (PAH) management has been transformed in recent times with the advent of cheap and effective diagnostic tools and therapy. Sildenafil, a phosphodiesterase-V inhibitor, has been at the centre of this treatment, and its success in treating PAH has led to its widespread uptake in adult and paediatric pulmonary hypertension (PH), as a first line treatment choice. This might apply to persistent pulmonary hypertension of the newborn (PPHN) or bronchopulmonary dysplasia, as well as to more complex diseases, such as idiopathic pulmonary hypertension...

The generation of rationally-designed polymer therapeutics via the conjugation of low molecular weight anti-cancer drugs to water-soluble polymeric nanocarriers aims to improve the therapeutic index. Here, we focus on applying polymer therapeutics to target two cell compartments simultaneously - tumor cells and angiogenic endothelial cells. Comparing different polymeric backbones carrying the same therapeutic agent and targeting moiety may shed light on any correlation between the choice of polymer and the anti-cancer activity of the conjugate...
