BACKGROUND: Creation of a new electronic health record (EHR)-based registry often can be a "one-off" complex endeavor: first developing new EHR data collection and clinical decision support tools, followed by developing registry-specific data extractions from the EHR for analysis. Each development phase typically has its own long development and testing time, leading to a prolonged overall cycle time for delivering one functioning registry with companion reporting into production. The next registry request then starts from scratch...

Programmed ribosomal frameshifting (PRF) is a translational anomaly causing the ribosome to shift into an alternative reading frame. PRFs are common in viral genomes, using a single nucleotide sequence to code for two proteins in overlapping frames. In bacteria and eukaryota, PRFs are less frequent. We report on a PRF in the copper detoxification system of Escherichia coli where a metallochaperone is generated out of the first 69 amino acids and a C-terminal out-of-frame glycine of the gene copA. copA besides codes for the P1B -ATPase CopA, a membrane-integral protein and principal interaction target of the chaperone...

CFS toolbox is an open-source collection of MATLAB functions that utilizes PsychToolbox-3 (PTB-3). It is designed to allow a researcher to create and run continuous flash suppression experiments using a variety of experimental parameters (i.e., stimulus types and locations, noise characteristics, and experiment window settings). In a CFS experiment, one of the eyes at a time is presented with a dynamically changing noise pattern, while the other eye is concurrently presented with a static target stimulus, such as a Gabor patch...

BACKGROUND: Transition is a passage or movement from one state, condition, or place to another. Patients with chronic disorders such as end-stage renal disease experience transitions. This study aims to explore the process of transition to hemodialysis. MATERIALS AND METHODS: This is a qualitative grounded theory of a doctoral dissertation. Twenty-four participants (19 patients on hemodialysis, 2 family members, 2 nurses, and a physician) were selected through purposive and theoretical sampling until data saturation...

Importance: Estimates from claims-based analyses suggest that the incidence of sepsis is increasing and mortality rates from sepsis are decreasing. However, estimates from claims data may lack clinical fidelity and can be affected by changing diagnosis and coding practices over time. Objective: To estimate the US national incidence of sepsis and trends using detailed clinical data from the electronic health record (EHR) systems of diverse hospitals. Design, Setting, and Population: Retrospective cohort study of adult patients admitted to 409 academic, community, and federal hospitals from 2009-2014...

The hippocampus is the main locus of episodic memory formation and the neurons there encode the spatial map of the environment. Hippocampal place cells represent location, but their role in the learning of preferential location remains unclear. The hippocampus may encode locations independently from the stimuli and events that are associated with these locations. We have discovered a unique population code for the experience-dependent value of the context. The degree of reward-driven navigation preference highly correlates with the spatial distribution of the place fields recorded in the CA1 region of the hippocampus...

The incidence of synchronous bilateral breast carcinomas (BBCs) has increased with a more frequent use of magnetic resonance imaging screening of the contralateral breast in women with newly diagnosed breast cancer. A total of 30% of all BBCs occur synchronously. In the present study, we describe a unique case of synchronous BBC in a 59-year-old previously healthy woman with no known family history of breast or ovarian cancer. At the time of diagnosis the patient had an invasive lobular carcinoma (ILC) in the right breast and an adenoid cystic carcinoma (ACC) in the left breast...

More than six decades ago Watson and Crick published the chemical structure of DNA. This discovery revolutionized our approach to medical science and opened new perspectives for the diagnosis and treatment of many diseases including cancer. Since then, progress in molecular biology, together with the rapid advance of technologies, allowed to clone hundreds of protein-coding genes that were found mutated in all types of cancer. Normal and aberrant gene functions, interactions, and mechanisms of mutations were studied to identify the intricate network of pathways leading to cancer...

There is a broad design space for concurrent computer processors: they can be optimized for low power, low latency or high throughput. This freedom to tune each processor design to its niche has led to an increasing diversity of machines, from powerful pocketable devices to those responsible for complex and critical tasks, such as car guidance systems. Given this context, academic concurrency research sounds notes of both caution and optimism. Caution because recent work has uncovered flaws in the way we explain the subtle memory behaviour of concurrent systems: specifications have been shown to be incorrect, leading to bugs throughout the many layers of the system...

The signal-to-noise ratio (SNR) and driving levels of capacitive touch sensors determine the applicability of these sensors to thinner displays and sensor-integrated modules. The simultaneous driving technique has been widely applied to capacitive touch sensors to cope with various types of environmental noise. A Hadamard matrix has been used to determine the driving code and multiplex capacitive signals required to increase the SNR and responsivity of touch sensors. Using multi-level Hadamard matrices, a new driving technique for sensing concurrent capacitive elements across multiple rows of a touch panel was developed...

BACKGROUND: Excess body weight and risky alcohol consumption are two of the greatest contributors to global disease. Health behaviours cluster in adolescence and track to adulthood. Very little is known about similar and contrasting influences on young people's eating behaviours and alcohol use. Whilst there are bodies of literature which explore the influences on young people's eating behaviour and alcohol consumption respectively, no qualitative studies have been identified with an explicit and concurrent focus on adolescent eating behaviours and alcohol consumption...

BACKGROUND: Progression from anorectal abscess to fistula is poorly described and it remains unclear which patients develop a fistula following an abscess. The aim was to assess the burden of anorectal abscess and to identify risk factors for subsequent fistula formation. METHODS: The Hospital Episode Statistics database was used to identify all patients presenting with new anorectal abscesses. Cox regression analysis was undertaken to identify factors predictive of fistula formation...

We describe a neonate born with complex arrhythmias that included concurrent atrial and ventricular tachycardias. Genetic testing demonstrated a mutation in the TTN gene, which codes for titin, a large protein found in striated muscle sarcomeres. The complex arrhythmias were successfully treated with amiodarone and flecainide. The patient remains asymptomatic with normal biventricular function. We speculate that the complex arrhythmias and TTN gene mutation may be related.

OBJECTIVES: Psychological morbidities after injury [eg, posttraumatic stress disorder (PTSD) and depression] are increasingly recognized as a significant determinant of overall outcome. Traumatic brain injury (TBI) negatively impacts outcomes of patients with orthopaedic injury, but the association of concurrent TBI, orthopaedic injury, and symptoms of PTSD and depression has not been examined. This study's objective was to examine symptoms of PTSD and depression in patients with orthopaedic trauma with and without TBI...

Bo Song, Yiming Zhao
Code-based cryptography is one of few alternatives supposed to be secure in a post-quantum world. Meanwhile, identity-based identification and signature (IBI/IBS) schemes are two of the most fundamental cryptographic primitives, so several code-based IBI/IBS schemes have been proposed. However, with increasingly profound researches on coding theory, the security reduction and efficiency of such schemes have been invalidated and challenged. In this paper, we construct provably secure IBI/IBS schemes from code assumptions against impersonation under active and concurrent attacks through a provably secure code-based signature technique proposed by Preetha, Vasant and Rangan (PVR signature), and a security enhancement Or-proof technique...

Epigenetics is defined as the heritable changes in gene expression patterns which are not directly encoded by modifications in the nucleotide DNA sequence of the genome, including higher order chromatin organization, DNA methylation, cytosine modifications, covalent histone tail modifications, and short non-coding RNA molecules. Recently, much attention has been paid to the role and the function of epigenetics and epimutations in the cellular and subcellular pathways and in the regulation of genes in the setting of both kidney and cardiovascular disease...

PURPOSE: The aim of this pilot study was to evaluate the potential of a new noninvasive optical measurement of muscle oxygenation (MOx) to identify shock severity in patients with suspected sepsis. METHODS: We enrolled 51 adult patients in the emergency department (ED) who presented with possible sepsis using traditional Systematic Inflammatory Response Syndrome criteria or who triggered a "Code Sepsis." Noninvasive MOx measurements were made from the first dorsal interosseous muscles of the hand once potential sepsis/septic shock was identified, as soon as possible after admission to the ED...

This study investigated whether temperamental approach-withdrawal underlies infants' responses to novel foods. Data were drawn from a longitudinal study of mother-infant dyads (n = 136). Approach-withdrawal responses to novel foods and novel toys were coded when infants were 6 and 12 months of age. When infants were 18 months of age, approach-withdrawal behaviors, positive affect, and negative affect were used in a latent profile analysis to identify groups of toddlers who exhibited similar responses to novelty...

INTRODUCTION: We sought to determine the value of obtaining preoperative urinary cytology when diagnostic workup of an upper tract mass is suspicious for upper tract urothelial carcinoma (UTUC), but biopsy fails to confirm the diagnosis. METHODS: Using billing code data, 239 patients were identified as having undergone radical nephroureterectomy (RNU) by 16 urologists from September 29, 1998 to July 31, 2015. Of this group, 19 adult patients had a presumed preoperative diagnosis of UTUC in a native kidney, at least three months of followup, no history of concurrent radical cystectomy with RNU, and negative/non-diagnostic tissue biopsy...
