PURPOSE: Optical see-through head-mounted displays (OST-HMD) feature an unhindered and instantaneous view of the surgery site and can enable a mixed reality experience for surgeons during procedures. In this paper, we present a systematic approach to identify the criteria for evaluation of OST-HMD technologies for specific clinical scenarios, which benefit from using an object-anchored 2D-display visualizing medical information. METHODS: Criteria for evaluating the performance of OST-HMDs for visualization of medical information and its usage are identified and proposed...

BACKGROUND Endocan is expressed in vascular endothelial cells, and its expression is enhanced following endothelial injury via inflammatory cytokines. Subsequently, endocan is secreted into the circulation. Thus, serum endocan levels are considered a marker of endothelial injury. However, to the best of our knowledge, no data on the serum endocan levels in peritoneal dialysis (PD) patients are available. MATERIAL AND METHODS This study included 21 PD patients who underwent peritoneal equilibration test (PET) more than once between 2011 and 2015...

Advanced age-related macular degeneration (AAMD) is a complex sight-threating disease of public health significance. Micro RNAs (miRNAs) have been proposed as biomarkers for AAMD. The presence of certain single nucleotide polymorphisms (SNPs) may influence the explanatory value of these biomarkers. Here we present findings from an integrated approach used to determine whether AAMD-associated SNPs have the capacity to influence miRNA-mRNA pairing and, if so, to what extent such pairing may be manifested in a discrete AAMD transcriptome...

REVIEW
Trevor Bennett, Katy Holloway
BACKGROUND: There is a growing body of research on the motives for prescription drug misuse (PDM) among university students. However, the overall findings of this research are hard to decipher. Studies use different methods, they examine different drug types, the motives are phrased in various ways, and the results differ widely. In order to make sense of this body of knowledge, it is necessary to synthesise the results across studies and draw out conclusions. METHODS: The research comprises a systematic review and meta-analysis of studies on the motives of university students for illicit use of four different types of prescription medication (stimulants, analgesics, tranquillisers and sedatives)...

Physicians must possess knowledge and skills to address the gaps facing the US health care system. Educators advocate for reform in undergraduate medical education (UME) to align competencies with the Triple Aim. In 2014, five medical schools and one state university began collaborating on these curricular gaps. The authors report a framework for the Science of Health Care Delivery (SHCD) using six domains and highlight curricular examples from each school. They describe three challenges and strategies for success in implementing SHCD curricula...

Inês Mahú, Ana I Domingos
In recent decades, obesity has become a global public health crisis irrespective of age or gender [21]. But according to historic records, concerns over appropriate maintenance of body size have been long established. For more than to 2 millennia, the main therapeutic approach to curb excess weight has been to recommend dietary restrictions and regular exercise (Haslam, 2016). Nevertheless, more contemporary studies indicate that the employment of such approaches in the treatment of severely obese patients causes metabolic adaptions which impair their long-term success in weight management [8]...

Tsetse flies (Diptera, Glossinidae) transmit human and animal trypanosomoses in Africa, respectively a neglected human disease (sleeping sickness) and the most important constraint to cattle production in infested countries (nagana). We recently developed a methodology to map landscape friction (i.e. resistance to movement) for tsetse in West Africa. The goal was to identify natural barriers to tsetse dispersal, and potentially isolated tsetse populations for targeting elimination programmes. Most species distribution models neglect landscape functional connectivity whereas environmental factors affecting suitability or abundance are not necessarily the same as those influencing gene flows...

The conjugation of small ubiquitin-like modifier (SUMO) to the target protein, namely, SUMOylation, is involved in the regulation of many important biological events including host-pathogen interaction. Some viruses have evolved to exploit the host SUMOylation machinery to modify their own protein. Retroviral Gag protein plays critical roles in the viral life cycle. The HIV-1 p6 and the Moloney murine leukemia virus CA have been reported to be conjugated with SUMO. In this study, we report for the first time, to our knowledge, the covalent conjugation of equine infectious anemia virus (EIAV) Gag with SUMO...

Beauveria bassiana is a fungus which is widely used as a biological insecticide to control a number of economically important insect pests. Knowledge of the genetic diversity of the isolates, understanding the underlying nature of these evolutionary phenomena and finding appropriate and simple screening tools play an important role in developing effective biocontrol agents. Here, we monitored changes of electrophoretic karyotype of small molecules of extrachromosomal DNAs, presumably mitochondrial DNA or plasmids in several individual isolates of B...

Lipids are essential components of exosomal membranes, and it is well-known that specific lipids are enriched in exosomes compared to their parent cells. In this review we discuss current knowledge about the lipid composition of exosomes. We compare published data for different lipid classes in exosomes, and what is known about their lipid species, i.e. lipid molecules with different fatty acyl groups. Moreover, we elaborate on the hypothesis about hand-shaking between the very-long-chain sphingolipids in the outer leaflet and PS 18:0/18:1 in the inner leaflet, and we propose this to be an important mechanism in membrane biology, not only for exosomes...

Radiologists in teaching hospitals and in practices with residents rotating through are involved in the education of their residents. The Accreditation Council for Graduate Medical Education requires evidence that trainees are taught and demonstrate competency not only in medical knowledge and in patient care-the historic focus of radiology education-but also in the so-called non-interpretative core competencies, which include professionalism and interpersonal skills. In addition to accreditation agencies, the prominent assessment practices represented by the American Board of Radiology core and certifying examinations for trainees, as well as Maintenance of Certification for practitioners, are planning to feature more non-interpretative competency assessment, including professionalism to a greater extent...

OBJECTIVE: To describe the development of cognitive task analysis (CTA)-based multimedia educational videos for surgical trainees in plastic surgery. DESIGN: A needs assessment survey was used to identify 5 plastic surgery skills on which to focus the educational videos. Three plastic surgeons were video-recorded performing each skill while describing the procedure, and were interviewed with probing questions. Three medical student reviewers coded transcripts and categorized each step into "action," "decision," or "assessment," and created a cognitive demands table (CDT) for each skill...

BACKGROUND: Uncontrolled hemorrhage is the leading cause of potentially preventable traumatic death. Bleeding victims must receive immediate medical attention to save lives, and the first opportunity to control bleeding after trauma often comes from bystanders. Educating the general public is important for improving outcomes for hemorrhaging victims, and it is imperative for all people, including those with no clinical training, to have the knowledge to respond until trained medical specialists arrive...

Ultrasound is widely used for medical diagnosis and increasingly for therapeutic purposes. An understanding of the bio-effects of sonography is important for clinicians and scientists working in the field because permanent damage to biological tissues can occur at high levels of exposure. Here the underlying principles of thermal mechanisms and the physical interactions of ultrasound with biological tissues are reviewed. Adverse health effects derived from cellular studies, animal studies and clinical reports are reviewed to provide insight into the in vitro and in vivo bio-effects of ultrasound...

Simulation in health care, a source of innovative pedagogical developments, is particularly well-suited to the training of nursing teams. It enables them to acquire or reinforce their knowledge, without any risk for the patients, in a calm and reassuring environment. In psychiatry in particular, the use of a room of errors constitutes a useful learning tool for professionals.

Endogenous and exogenous reactive species cause oxidatively induced DNA damage in living organisms by a variety of mechanisms. As a result, a plethora of mutagenic and/or cytotoxic products are formed in cellular DNA. This type of DNA damage is repaired by base excision repair, although nucleotide excision repair also plays a limited role. DNA glycosylases remove modified DNA bases from DNA by hydrolyzing the glycosidic bond leaving behind an apurinic/apyrimidinic (AP) site. Some of them also possess an accompanying AP-lyase activity that cleaves the sugar-phosphate chain of DNA...

The sub-Antarctic Magellanic ecoregion is a part of the world where ecosystems have been understudied and where the CH4 cycling and emissions in lakes has not ever been reported. To fill that knowledge gap, a lake and a reservoir located at 53°S were selected and studied during three campaigns equally distributed over one year. Among the parameters measured were CH4 and CO2 emissions, as well their dissolved concentrations in the water column, which were determined with high spatial resolution. No ebullition was observed and the CH4 flux ranged from 0...
