BACKGROUND AND OBJECTIVES: Physicians must communicate effectively with patients. Actual patients (APs) rarely evaluate medical students' clinical skills; instead, standardized patients (SPs) provide proxy ratings. It is unclear how well SP ratings mirror AP experiences. The aim of this study was to compare AP and SP assessments of medical students' communication skills and professionalism. We hypothesized that their perspectives would be similar, but distinct, and offer insight about how to more reliably include the patient's voice in medical education...

BACKGROUND: Over the last twenty years, predicting psychosis has become a priority of both research and policies. Those approaches include the use of the At Risk Mental State category (ARMS) and of standardized predictive tools. In comparison to most developed countries, early interventions programs are only little developed in France. However, cases of young patients presenting unclear symptoms that might be a beginning psychosis or might as well reflect some adolescent unease are commonplace in psychiatry...

The developing region of SAARC (South Asian Association for Regional Cooperation) is home to a large number of people living below the poverty line. In future, providing affordable, universally accessible, reliable, low to zero carbon electricity in this region will be the main aim. A cost optimal 100% renewable energy system is simulated for SAARC for the year 2030 on an hourly resolved basis. The region was divided into 16 sub-regions and three different scenarios were set up based on the level of high voltage direct current (HVDC) grid connections...

INTRODUCTION: Intoxication often prevents clinical clearance of the cervical spine (Csp) after trauma leading to prolonged immobilization even with a normal CT scan. We evaluated the accuracy of CT at detecting clinically significant Csp injury, and surveyed participants on related opinions and practice. METHODS: A prospective multicenter study (2013-2015) at 17 centers. All adult blunt trauma patients underwent structured clinical examination and imaging including a Csp CT, with follow-up thru discharge...

As the older adult population in the United States continues to grow, developing reliable, valid, and practical methods for identifying fall risk is a high priority. Falls are prevalent in older adults and contribute significantly to morbidity and mortality rates and rising health costs. Identifying at-risk older adults and intervening in a timely manner can reduce falls. Conventional fall risk assessment tools require a health professional trained in the use of each tool for administration and interpretation...

Graphene as a transducer material has produced some of the best-performing sensing approaches to date opening the door toward integrated miniaturized all-carbon point-of-care devices. Addressing this opportunity, laser-scribed graphene (LSG) electrodes are demonstrated here as highly sensitive and reliable biosensor transducers in blood serum analysis. These flexible electrodes with large electrochemical surface areas were fabricated using a direct-write laser process on polyimide foils. A universal immobilization approach is established by anchoring 1-pyrenebutyric acid to the graphene and subsequently covalently attaching an aptamer against the coagulation factor thrombin as an exemplary bioreceptor to the carboxyl groups...

The development of simple yet ultrasensitive biosensing approaches for the detection of cancer prognostic microRNA is an important step toward their successful clinical implementation. We demonstrate the relevance for the detection of circulating miRNA of a novel signal amplification scheme based on surface plasmon resonance enhanced light scattering (SP-LS). In addition to experimental optimization carried out using gold nanoparticle (AuNP) tags conjugated with a monoclonal antibody with high affinity for RNA*DNA hybrid duplexes, simulation modeling was conducted to obtain insights about SP-LS biosensing...

Nerve agents are highly toxic organophosphorus compounds, and their possible use in terrorist attacks has led to increasing interest in the development of reliable and accurate methods to detect these lethal chemicals. In this paper, we have prepared six 6-aminoquinolines with various N-substituents as chemosensors for a nerve-agent mimic diethylchlorophosphate (DCP). The chemosensors with the nucleophilic pyridine-N atom as the active site detect DCP via a catalytic hydrolysis approach to form the protonated sensor...

The number of publications in the field of chemical cross-linking/mass spectrometry (MS) for deriving protein 3D structures and for probing protein/protein interactions has largely increased during the last years. MS analysis of the large cross-linking datasets requires an automated data analysis by dedicated software tools, but applying scoring procedures with statistical methods does not eliminate the fun-damental problems of a misassignment of cross-linked products. In fact, we have observed a significant rate of misassigned cross-links in a number of publications, mainly due to the presence of isobaric cross-linked species, an incomplete fragmentation of cross-linked products, and low-mass accuracy fragment ion data...

Chemical derivatization is a simple approach for stable-isotope covalent labeling of proteins in quantitative proteomics. Herein we describe the development of a novel maleyl-labeling-based approach for protein quantification. Under optimized conditions, maleic anhydride can serve as a highly-efficient reagent to label the amino groups of tryptic peptides. Furthermore, 'click chemistry'was successfully applied to obtain the second modification of maleylated peptides via thiol-Michael addition reaction. Accurate quantification was further achieved via the first or/and second step stable-isotope labeling in this study...

Semiconductor integrated circuit chip industries have been striving to introduce porous ultralow-k (ULK) dielectrics into the multilevel interconnection process in order to improve their chip operation speed by reducing capacitance along the signal path. To date, however, highly porous ULK dielectrics (porosity > 40%, dielectric constant (k) < 2.4) have not been successfully adopted in real devices because the porous nature causes many serious problems including non-continuous barrier deposition, penetration of the barrier metal, and reliability issues...

The invasive nature of surgical biopsies deters sequential application, and single biopsies often fail to reflect tumor dynamics, intratumor heterogeneity and drug sensitivities likely to change during tumor evolution and treatment. Implementing molecular characterization of cell-free neuroblastoma-derived DNA isolated from blood plasma could improve disease assessment for treatment selection and monitoring of patients with high-risk neuroblastoma. We established droplet digital PCR (ddPCR) protocols for MYCN and ALK copy number status in plasma from neuroblastoma patients...

The detection of highly toxic chemicals in a convenient, fast, and reliable manner is essential for coping with serious threats to humankind and public security caused by unexpected terrorist attacks and industrial accidents. In this paper, a highly selective fluorescent probe has been constructed through o-phenylenediamine covalently linking to coumarin (o-Pac), which can respond to phosgene in turn-on fluorescence mode. The response time is less than 0.5 min and the detection limit is as low as 3 nM in solutions...
