Background and aims The 2011 UN Summit on Non-Communicable Disease failed to call for global action on alcohol marketing despite calls in the World Health Organization (WHO) Global Action Plan on Non-Communicable Diseases 2013-20 to restrict or ban alcohol advertising. In this paper we ask what it might take to match the global approach to tobacco enshrined in the Framework Convention on Tobacco Control (FCTC), and suggest that public health advocates can learn from the development of the FCTC and the Code of Marketing on infant formula milks and the recent recommendations on restricting food marketing to children...

Fabricating nano-sized through-holes on a coverslip approximately 100 μm thick is challenging but rewarding when applied to ultrafine filters that separate proteins and DNA of various sizes and isolate viruses from cells. Toward this end, we developed an in situ etching-assisted laser processing technique exploiting gold nanoparticles. Plasmonic heating of a single gold nanoparticle through focused illumination of a continuous-wave laser beam enables structural modifications to be localized to the contact area on the glass surface...

Robot-assisted gastrectomy has been reported to be a safe alternative to both conventional laparoscopy and the open approach for treating early gastric carcinoma. Currently, there are a limited number of published reports on this technique in the literature. We assessed the current status of robotic and laparoscopic surgery in the treatment of gastric cancer and compared the operative outcomes, learning curves, and oncological outcome of the two approaches. Robotic gastrectomy offers benefits that include increased ease of performing D2 lymph node dissection and reduced blood loss compared with laparoscopic gastrectomy...

Segmentation of infarcts at hyperacute stage is challenging as they exhibit substantial variability which may even be hard for experts to delineate manually. In this paper, a sparse representation based classification method is explored. For each patient, four volumetric data items including three volumes of diffusion weighted imaging and a computed asymmetry map are employed to extract patch features which are then fed to dictionary learning and classification based on sparse representation. Elastic net is adopted to replace the traditional L0-norm/L1-norm constraints on sparse representation to stabilize sparse code...

Hypodermic injections have been the standard for transcutaneous drug delivery for many years. However, needle phobia, pain, and risks of needle-stick injuries have manifested in poor patient compliance. Needle-free jet injections (NFJI) have been developed to address these drawbacks but the reliability of dose and depth of delivery have been limited by a lack of control over jet parameters, and by variability in the skin's mechanical properties among individuals. Moreover, the device size and cost have been restrained by the high pressure (>20MPa) required to penetrate the skin...

Using the bivalve macrofouler Corbicula fluminea, the suitability of in vitro testing as a stepping stone towards the improvement of control methods based on chemical mixtures was addressed in this study. In vitro cholinesterase (ChE) activity inhibition following single exposure of C. fluminea tissue to four model chemicals (the organophosphates dimethoate and dichlorvos, copper and sodium dodecyl phosphate [SDS]) was first assessed. Consequently, mixtures of dimethoate with copper and dichlorvos with SDS were tested and modelled; mixtures with ChE revealed synergistic interactions for both chemical pairs...

Chronic wound fluids have elevated concentration of human neutrophil elastase (HNE) which can be used as inflammation/infection marker. Our goal is to develop functional materials for fast diagnosis of wound inflammation/infection by using HNE as a specific marker. For that, fluorogenic peptides with a HNE-specific cleavage sequence were incorporated into traditional textile dressings, to allow real-time detection of the wound status. Two different fluorogenic approaches were studied in terms of intensity of the signal generated upon HNE addition: a fluorophore 7-amino-4-trifluormethylcoumarin (AFC) conjugated to a HNE-specific peptide and two fluorophore/quencher pairs (FAM/Dabcyl and EDANS/Dabcyl) coupled to a similar peptide as a Förster resonance energy transfer (FRET) strategy...

BACKGROUND: Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous ISusing widely available central venous catheter and controlled suction cannula. METHODS: We used a controlled suction cannula attached to a central suction system. Single lumen central venous catheter is passed through the key hole of a controlled suction cannula, which is connected to a continuous irrigation system...

The recent literature on transcatheter aortic valve replacement (TAVR) is shedding new light on the perspective to extend this procedure to other lower risk-category of patients, leading in fact to a potential erosion of the current guidelines. Notwithstanding the warnings provided in the literature regarding the risk of severely impairing complications, unclear survival advantage and cost-inefficiency, many observational studies, especially performed in high-volume centers, support a general drive toward the recruitment of intermediate-low risk patients in the expectation of clinical advantages versus standard surgical replacement...

A model for patient-specific cardiac mechanics simulation is introduced, incorporating a 3-dimensional finite element model of the ventricular part of the heart which is coupled to a reduced-order 0-dimensional closed-loop vascular system, heart valve and atrial chamber model.The ventricles are modeled by a nonlinear orthotropic passive material law. The electrical activation is mimicked by a prescribed parametrized active stress acting along a generic muscle fiber orientation. Our activation function is constructed such that the start of ventricular contraction and relaxation as well as the active stress curve's slope are parameterized...

BACKGROUND: After comparing with open approach, left lateral sectionectomy (LLS) has become standard in terms of short-term outcomes without jeopardizing long-term survival when performed for malignancy. The aim of this study was to compare the short-term and economic outcomes of laparoscopic (L-LLS) and robotic (R-LLS) LLS. METHODS: All consecutive patients who underwent L-LLS or R-LLS from 1997 to 2014 were analyzed. Short-term and economic outcomes were compared between the two groups using a propensity score matching (PSM)...

Identification of bacteria in aquatic and environmental applications, for monitoring purposes and research, for health assessments and therapy considerations of farmed and free-living aquatic organisms, still relies on conventional phenotypic and biochemical protocols. Although molecular techniques based on DNA amplification and sequencing are finding ways into diagnostic laboratories, they are time-consuming, costly and difficult in the case of multiplex assays. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is a rapid and accurate proteomic method reliable for identification of unknown bacteria to the genus and species level...

PURPOSE OF REVIEW: Low cost, avoidance of irradiation, and high temporal resolution are inherent advantages of ultrasound imaging that translate into multiple clinical uses in many domains of neurology. This article presents clinical uses of ultrasound examination in cerebrovascular, neurodegenerative, and peripheral nervous system diseases. RECENT FINDINGS: Modern treatment and prevention of ischemic stroke rely on prompt diagnosis. Ultrasonography has found a place as a noninvasive screening test and bedside technique that provides estimates of the degree of stenosis as well as hemodynamic and structural information about intracranial and extracranial vessels in real time...

We present a high-throughput and scalable technique for the production of metal nanowires embedded in glass fibres by taking advantage of thin film properties and patterning techniques commonly used in planar microfabrication. This hybrid process enables the fabrication of single nanowires and nanowire arrays encased in a preform material within a single fibre draw, providing an alternative to costly and time-consuming iterative fibre drawing. This method allows the combination of materials with different thermal properties to create functional optoelectronic nanostructures...

Routine quality control is a critical aspect of properly maintaining high-performance small animal imaging instrumentation. A robust quality control program helps produce more reliable data both for academic purposes and as proof of system performance for contract imaging work. For preclinical imaging laboratories, the combination of costs and available resources often limits their ability to produce efficient and effective quality control programs. This work presents a series of simplified quality control procedures that are accessible to a wide range of preclinical imaging laboratories...

BACKGROUND: Intrauterine growth retardation (IUGR) is a major risk factor for perinatal mortality and morbidity. Thus, there is a compelling need to introduce sensitive measures to detect IUGR fetuses. Routine third trimester ultrasonography is increasingly used to detect IUGR. However, we lack evidence for its clinical effectiveness and cost-effectiveness and information on ethical considerations of additional third trimester ultrasonography. This nationwide stepped wedge cluster-randomized trial examines the (cost-)effectiveness of routine third trimester ultrasonography in reducing severe adverse perinatal outcome through subsequent protocolized management...

A key outcome measure of cancer research training programs is the number of cancer-related peer-reviewed publications after training. Because program graduates do not routinely report their publications, staff must periodically conduct electronic literature searches on each graduate. The purpose of this study is to compare findings of an innovative computer-based automated search program versus repeated manual literature searches to identify post-training peer-reviewed publications. In late 2014, manual searches for publications by former R25 students identified 232 cancer-related articles published by 112 of 543 program graduates...

BACKGROUND: Local anaesthetics play a key role in reducing pain and anxiety during dental treatment. However the disadvantage of using syringe and needle technique in the maxilla, proximal to the apices of the teeth is that it is painful and also leads to collateral anaesthesia. Hence this systematic review aims to identify whether computer assisted local anaesthetic delivery system could produce predictable results similar to conventional syringe needle technique and also eliminate the disadvantages...
