Lisa N Jefferies, Vincent Di Lollo
The main question examined in the present work was whether spatial attention can be deployed to an appropriate structural framework not only endogenously when the framework is displayed continuously, as in previous work, but also exogenously, when it is displayed transiently 100 ms before the target. The results of five experiments answered that question in the negative. We found that the onset transient triggered by a brief presentation of the structural framework did enhance the response to the upcoming target...

In this article, we examine the performance of different eye blink detection algorithms under various constraints. The goal of the present study was to evaluate the performance of an electrooculogram- and camera-based blink detection process in both manually and conditionally automated driving phases. A further comparison between alert and drowsy drivers was performed in order to evaluate the impact of drowsiness on the performance of blink detection algorithms in both driving modes. Data snippets from 14 monotonous manually driven sessions (mean 2 h 46 min) and 16 monotonous conditionally automated driven sessions (mean 2 h 45 min) were used...

PURPOSE: The use of potentially inappropriate medications (PIMs) in hospitalized older adults is a complex problem, but the use of computerized alert systems (CAS) has shown some potential. The study's objective is to assess the change in PIM use with a CAS-based pharmacist-physician intervention model compared to usual clinical care. METHODS: Pragmatic single-site randomized controlled trial was conducted at a university teaching hospital. Hospitalizations identified with selected Beers or STOPP criteria were randomized to usual clinical care or to the CAS-based pharmacist-physician intervention...

The prolyl hydroxylase domain-containing enzymes (PHDs) are important metabolic sensors of the cell and its environment, which might be employed to alert cells of the immune system. These enzymes regulate the expression of the hypoxia inducible factor (HIF) isoforms and NF-κB, crucial transcription factors controlling cellular metabolism and inflammation. PHD/HIF signaling is activated in the allergic lung and is proposed as a potential druggable pathway. Here, we investigated the regulation and role of the PHD isoforms in CD11c-expressing dendritic cells (DCs) and macrophages (Mϕ), sensors of the environment and crucial antigen-presenting cells in the pathogenesis of asthma...

BACKGROUND: Stroke is a critical public health issue in the United States and globally. System models to optimally capture stroke incidence in rural and culturally diverse communities are needed. The epidemiological transition to a western lifestyle has been associated with an increased burden of vascular risk factors among Alaska Native (AN) people. The burden of stroke in AN communities remains understudied. METHODS: The Alaska Native Stroke Registry (ANSR) was designed to screen and capture all stroke cases between 2005 and 2009 through its integration into the existing single-payer Alaska Tribal Health System infrastructure...

The brain constantly has to interpret stimuli from a range of modalities originating from the same or different objects to create unambiguous percepts. The mechanisms of such multisensory processing have been intensely studied with respect to the time window of integration or the effect of spatial separation. However, the neural mechanisms remain elusive with respect to the role of alerting effects and multisensory integration. We addressed this issue by choosing a test paradigm where we could manipulate potentially alerting stimuli and simultaneously activating stimuli independently: We measured the temporal ventriloquism effect in European starlings by using the temporal order judgment paradigm with subjects judging the temporal order of the lighting of 2 spatially separated lights...

Despite effective treatment for chronic hepatitis C (CHC), deficiencies in diagnosis and access preclude disease elimination. Screening of baby boomers remains low. The aims of this study were to assess the impact of an electronic health record (EHR) based prompt on HCV screening rates in baby boomers in primary care, and access to specialty care and treatment among those newly diagnosed. We implemented an EHR based "Best Practice Advisory" (BPA) that prompted primary care providers (PCPs) to perform HCV screening for patients seen in primary care clinic: 1) born between 1945-1965; 2) lacked a prior diagnosis of HCV infection; and 3) lacked prior documented anti-HCV testing...

BACKGROUND: Recognizing that attention is not a unitary system, the Attention Network Test (ANT) and its variants were developed to measure the efficacy of the multiple components of attention. One potential weakness of these tests (ANTs) is that they are unengaging. This poses a problem when particular groups are tested (e.g., young children), when more stable measures of performance are desirable (and can only be achieved in longer testing sessions) and when repeated testing is necessary...

OBJECTIVE: To investigate the predictive value of weight restoration trajectories for relapse within the first year after discharge from inpatient treatment among adolescents with AN. METHODS: Forty four inpatient adolescents (5 boys, 39 girls) aged 11-18 (M 14.85, SD 1.87) diagnosed with anorexia were assessed at admission and discharge from a general hospital inpatient ward. Re-hospitalizations within 1 year of discharge were recorded. Factors assessed included 1/BMI at admission, 2/BMI at discharge, 3/percent from target weight (PFTW) at discharge, 4/length of hospitalization, and 5/a weight restoration trajectory measuring weight drops during inpatient weight restoration (rates of negative cubic variation in body weight (NCV)...

Psychological stress triggers headaches, but how this happens is unclear. To explore this, 38 migraine sufferers, 28 with tension-type headache (T-TH) and 20 controls rated nausea, negative affect, task-expectancies and headache at 5-min intervals during an aversive 20-min mental arithmetic task with a fixed failure rate. Blood pressure and pulse rate were measured every 3 min and salivary cortisol was sampled before and after the task. Multiple regression analysis indicated that irritation, anxiety and the absence of sluggishness (i...

Acute kidney injury in children is associated with adverse outcomes, although much of our current understanding originates from studies in intensive care units. Holmes et al. used an automated acute kidney injury detection method to obtain epidemiologic data on pediatric acute kidney injury at a national level in outpatient, inpatient, and intensive care unit settings. We discuss the impact of these important results and the considerations needed with this approach.

Arousal sometimes enhances and sometimes impairs perception and memory. A recent theory attempts to reconcile these findings by proposing that arousal amplifies the competition between stimulus representations, strengthening already strong representations and weakening already weak representations. Here, we report a stringent test of this arousal-biased competition theory in the context of focused visuospatial attention. Participants were required to identify a briefly presented target in the context of multiple distractors, which varied in the degree to which they competed for representation with the target, as revealed by psychophysics...

Soil contamination may result from the inadequate disposal of substances with polluting potential or prolonged agricultural use. Therefore, cadmium (Cd), chromium (Cr) and nickel (Ni) concentrations were assessed in a Eutroferric Red Oxisol under a no-tillage farming system with mineral fertilizer applications, a conventional tillage system with mineral fertilizer application and a conventional tillage system with sewage sludge application in an area used for agriculture for more than 80 years. We evaluated the spatial distributions of these elements in the experimental area and the effect of the different management practices on the soil retention of these metals...

Research based in the United States, with its relatively open educational system, has found that personality mediates the relationship between parents' and child's educational attainment and this mediational pattern is especially beneficial to students from less-educated households. Yet in highly structured, competitive educational systems, personality characteristics may not predict attainment or may be more or less consequential at different points in the educational career. We examine the salience of personality in the educational attainment process in the German educational system...
