BACKGROUND: Poor medication adherence has been shown to cause medical complications, death, and increased healthcare costs and may be of particular importance in patients with substance use disorder (SUD). Concerns regarding adherence in this population may influence a healthcare provider's decision to prescribe a medication requiring high adherence. Guidance defining best practices that promote adherence among individuals with SUD is lacking. METHODS: A review of English articles in Medline and PsycINFO databases, published between October 1, 1994 and October 31, 2017, was conducted in order to identify studies of interventions intended to improve adherence to oral chronic disease medication regimens among patients with SUD...

Multiple environmental stressors, including nutrient effluents (i.e. nitrates [NO3 - ]) and altered pH regimes, influence the persistence of freshwater species in anthropogenically disturbed habitats. Independently, nitrate and low pH affect energy allocation by increasing maintenance costs and disrupting oxygen uptake, which ultimately results in impacts upon whole animal performance. However, the interaction between these two stressors has not been characterised. To address this, the effects of nitrate and pH and their interaction on aerobic scope and physiological performance were investigated in the blueclaw crayfish, Cherax destructor...

This study reports for the first time temporal trends for the period of 2011-2016 in 137 Cs content in cow's milk originating from private farms and households of 14 settlements located in the territories of the Rivne region, Ukraine. These areas are still radioactively contaminated as a result of the accident at the Chernobyl Nuclear Power Plant (ChNPP) in 1986. In 2016, the average 137 Cs activity concentration in milk exceeded the Ukrainian Permissible Level (PL) for adults of 100 Bq/l in samples from 6 settlements and the PL for children of 40 Bq/l in 8 settlements, reaching activity concentration of around 500 Bq/l in some samples...

In Germany, Farm Management Systems (FMS) have been introduced as a support to farmers' compliance with environmental and other regulations, aiming at the increase of farm level performance and sustainable farming practices. Different kinds of FMS were developed and promulgated with various approaches, determined by each federal state's agricultural advisory system. Knowledge on the FMS' uptake and effectiveness has been lacking so far. The overall aim of this paper is to provide an analysis of the implementation process and selected outcomes of the policy-driven instrumental innovation of FMS...

BACKGROUND & AIMS: There have been few studies of abdominal imaging screening of individuals at high risk for pancreatic cancer (based on family history or genetic variants). We performed a meta-analysis of prospective cohort studies to determine the diagnostic yield and outcomes of abdominal imaging screening for asymptomatic individuals at high risk. METHODS: Through a systematic review of multiple electronic databases and conference proceedings through July 2017, we identified prospective cohort studies (>20 patients) of asymptomatic adults determined to be at high-risk of pancreatic cancer (lifetime risk >5%, including specific genetic-associated conditions) who were screened by endoscopic ultrasound (EUS) and/or magnetic resonance imaging (MRI) to detect pancreatic lesions...

BACKGROUND: Without an effective vaccine, hepatitis C virus (HCV) remains a global threat, inflicting 170-300 million carriers worldwide at risk of cirrhosis and hepatocellular carcinoma (HCC). Though various direct acting antivirals have been redeemed the hepatitis C treatment, a few restraints persist including possible side effects, viral resistance emergence, excessive cost which restricts its availability to a common person. HYPOTHESIS: There is no preventive HCV vaccine available today so the discovery of potent antiviral natural flora and their bioactive constituents may help to develop preventive cures against HCV infection...

REVIEW
Djordje Atanackovic, Tim Luetkens
In the past few years we have seen remarkable paradigm shifts in the treatment of many solid tumors due to the introduction of inhibitors targeting immune checkpoints such as PD-1/PD-L1 and CTLA-4. Recent results indicate that checkpoint inhibition also represents a very promising approach for certain types of hematologic malignancies. Unfortunately, treatment with checkpoint inhibitors is also associated with substantial toxicities and high costs and only a subset of patients appears to derive clinical benefit from these treatments...

Formation of scars following wounding or trauma represents a significant healthcare burden costing the economy billions of dollars every year. Activation of focal adhesion kinase (FAK) has been shown to play a pivotal role in transducing mechanical signals to elicit fibrotic responses and scar formation during wound repair. We have previously shown that inhibition of FAK using local injections of a small molecule FAK inhibitor (FAKI) can attenuate scar development in a hypertrophic scar model. Clinical translation of FAKI therapy has been challenging, however, due to the lack of an effective drug delivery system for extensive burn injuries, blast injuries, and large excisional injuries...

BACKGROUND: Multimodal interventions are effective in increasing hand hygiene (HH) compliance amongst healthcare workers, but it is not known whether such interventions are cost-effective outside high-income countries. AIM: To evaluate the cost-effectiveness of multimodal hospital interventions to improve hand hygiene (HH) compliance in a middle-income country. METHOD: We adopted a conservative approach by developing a model to determine whether reductions in Methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA-BSI) alone would make HH interventions cost-effective in intensive care units (ICUs)...

Prolonged postoperative air leaks are associated with extended periods of postoperative hospitalization, increased hospital costs, and an increased incidence of major cardiopulmonary complications. To prevent prolonged air leaks, we used small pieces of polyglycolic acid mesh as a pledget during the stitching of air leak sites. The stitched sites were then covered with mesh and fibrin glue. This novel technique showed the highest airway pressure tolerance in an ex vivo experimental study. There were no incidents of prolonged air leak among the five clinical cases in which this technique was initially applied...

Triple combinations of antiretroviral (ART) drugs are the standard treatment for HIV infection, but the challenges include long-term side effects, high costs, and adherence. The recent advent of potent and well tolerated ART has renewed the interest for newer ART strategies. A dual regimen with the combination of dolutegravir (DTG) and rilpivirine (RPV), two well tolerated, metabolic-friendly, and potent drugs could offer additional benefits. Areas covered: A review of recent randomized trials and observational cohorts concerning the use of a dual therapy with DTG plus RPV as a switching strategy in patients with viral suppression...

PURPOSE: One of the most important implications of 'Radiation Biology' research is to improve cancer radiotherapy with minimum side effects. In this regard, combination of chemotherapy with radiation has significantly improved tumor control as well as overall survival in a variety of cancers. However, this has been achieved at the cost of significant normal tissue toxicity, due to the lack of specificity of chemotherapy. Membrane-localized receptor tyrosine kinases (RTKs) have been found to play a driving role in various hallmarks of cancer...

The ability to measure single quanta allows the complete characterization of small quantum systems known as full-counting statistics. Quantum gas microscopy enables one to observe many-body systems at the single-atom precision. We extend the idea of full-counting statistics to nonequilibrium open many-particle dynamics and apply it to discuss the quench dynamics. By way of illustration, we consider an exactly solvable model to demonstrate the emergence of unique phenomena such as nonlocal and chiral propagation of correlations, leading to a concomitant oscillatory entanglement growth...

This letter describes a low-cost, scalable nanomanufacturing process that enables the continuous forming of thin metallic layers with nanoscale accuracy using roll-to-roll, laser-induced superplasticity (R2RLIS). R2RLIS uses a laser shock to induce the ultrahigh strain rate deformation of metallic films at room temperature into low-cost polymeric nanomolds, independently of the original grain size of the metal. This simple and inexpensive nanoforming method does not require access to cleanrooms and associated facilities, and can be easily implemented on conventional CO2 lasers, enabling laser systems commonly used for rapid prototyping or industrial cutting and engraving to fabricate uniform and three-dimensional crystalline metallic nanostructures over large areas...

We developed a novel neural network based force field for water based on training with high level ab initio theory. The force field was built based on electrostatically embedded many-body expansion method truncated at binary interactions. Many-body expansion method is a common strategy to partition the total Hamiltonian of large systems into a hierarchy of few-body terms. Neural networks were trained to represent electrostatically embedded one-body and two-body interactions, which require as input only one and two water molecule calculations at the level of ab initio electronic structure method CCSD/aug-cc-pVDZ embedded in the molecular mechanics water environment, making it efficient as a general force field construction approach...

Thermoelectric materials, capable of interconverting heat and electricity, are attractive for applications in thermal energy harvesting as a means to power wireless sensors, wearable devices and portable electronics. However, traditional inorganic thermoelectric materials pose significant challenges due to high cost, toxicity, scarcity, as well as brittleness particularly when it comes to applications requiring flexibility. Here, we investigate organic-inorganic nanocomposites that have been developed from bespoke inks which are printed via an aerosol jet printing method onto flexible substrates...

Aluminum-air batteries are a promising power supply for electronics due to its low cost and high energy density. However, portable coin-type Al-air batteries operating under ambient air condition for small electronic appliances have rarely been reported. Herein, coin cell-type Al-air batteries using cost-effective and eco-friendly chitosan hydrogel membranes modified by SiO2, SnO2, and ZnO have been prepared and assembled. The Al-air coin cell employing chitosan hydrogel membrane containing 10 wt.% SiO2 as a separator exhibits better discharge performance with a higher flat voltage plateau, longer discharge duration, and higher power density than the cells using a chitosan hydrogel membrane containing SnO2 or ZnO...
