Multifunctional Structural Supercapacitor Composites Based on Carbon Aerogel Modified High Performance Carbon Fiber Fabric

It is well documented that bedrest has adverse outcomes for hospitalized patients. This is especially true for critically ill patients due to life support measures, invasive catheters, and mechanical ventilation. Consequences associated with bedrest in critical care patients include venous thromboembolism, ventilator associated pneumonia, pressure ulcer development, and muscle weakness. Respiratory muscle weakness is associated with prolonged ventilator support and delayed extubation. The Awakening and Breathing Coordination, Delirium Monitoring and Management, and Early Mobility (ABCDE) bundle uses evidence based practice to prevent and treat ICU acquired delirium and weakness. The bundle aims to do this by standardizing care processes in collaboration with the ICU team to promote early mobility in ventilated patients. The purpose of this research study was to determine if the implementation of an early mobility protocol decreased the number of ventilator days for patients who receive mechanical ventilation. A retrospective chart review was conducted at a 16 bed ICU. Group A included 30 subjects (n=30) who were treated pre implementation of the ABCDE bundle and Group B included 39 (n=39) subjects who were treated post implementation of the ABCDE bundle. There were less average ventilator days found in Group A in comparison to Group B. Additionally, there was a significant difference found in the ICU length of stay pre implementation (M=9.4, SD=4.4) and post implementation (M=5.7, SD=2.6) of the ABCDE bundle for early mobility, t (65) =4.3, p = 0.00005. The APRN can use the evidence in the ABCDE bundle to guide care to critically ill patients that are mechanically ventilated. Utilizing the ABCDE bundle additionally allows the APRN to be instrumental in improving patient outcomes through interdisciplinary collaboration

Nanocomposite coatings obtained by electrophoretic co-deposition of poly(etheretherketone)/graphene oxide suspensions

Nanocomposite coatings were successfully prepared by electrophoretic deposition of poly(etheretherketone) (PEEK)/graphene oxide (GO) suspensions. The GO flakes developed a large-scale co-continuous morphology with the basal plane mainly aligned with the coating surface. However, the PEEK particles were also found to be wrapped by GO nanosheets when deposited on the stainless steel substrate. Both phenomena, the co-continuous morphology and the wrapping effect, were dependent on the initial GO content in the suspension and influenced the final morphological characteristics of the thermally treated coatings. The PEEK matrix developed a dendritic morphology during its cooling from the molten state because of transcrystallinity that was induced by the incorporation of GO. The preparation of suspensions involved tip ultrasonication (TS) to deagglomerate, disperse, and mill the PEEK particles. A detailed study of the microstructure revealed that TS tended not only to reduce PEEK particle size, but also to promote an elongated shape, favourable for the nanocomposite coatings

The 'At-risk mental state' for psychosis in adolescents : clinical presentation, transition and remission.

Despite increased efforts over the last decade to prospectively identify individuals at ultra-high risk of developing a psychotic illness, limited attention has been specifically directed towards adolescent populations (<18 years). In order to evaluate how those under 18 fulfilling the operationalised criteria for an At-Risk Mental State (ARMS) present and fare over time, we conducted an observational study. Participants (N = 30) generally reported a high degree of functional disability and frequent and distressing perceptual disturbance, mainly in the form of auditory hallucinations. Seventy percent (21/30) were found to fulfil the criteria for a co-morbid ICD-10 listed mental health disorder, with mood (affective; 13/30) disorders being most prevalent. Overall transition rates to psychosis were low at 24 months follow-up (2/28; 7.1 %) whilst many participants demonstrated a significant reduction in psychotic-like symptoms. The generalisation of these findings may be limited due to the small sample size and require replication in a larger sample

Echocardiographic detection of anomalous course of the left innominate vein

Anomalous course of the left innominate vein beneath the aortic arch is a rare congenital anomaly. We report the case of a 3 year old child in whom this defect was detected by two-dimensional and Doppler echocardiography. The echocardiographic appearance of the anomalous course of the left innominate vein is illustrated and the importance of identifying this rare systemic venous anomaly is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42535/1/10554_2005_Article_BF01784202.pd

Heritable patterns of tooth decay in the permanent dentition: principal components and factor analyses

<p>Abstract</p> <p>Background</p> <p>Dental caries is the result of a complex interplay among environmental, behavioral, and genetic factors, with distinct patterns of decay likely due to specific etiologies. Therefore, global measures of decay, such as the DMFS index, may not be optimal for identifying risk factors that manifest as specific decay patterns, especially if the risk factors such as genetic susceptibility loci have small individual effects. We used two methods to extract patterns of decay from surface-level caries data in order to generate novel phenotypes with which to explore the genetic regulation of caries.</p> <p>Methods</p> <p>The 128 tooth surfaces of the permanent dentition were scored as carious or not by intra-oral examination for 1,068 participants aged 18 to 75 years from 664 biological families. Principal components analysis (PCA) and factor analysis (FA), two methods of identifying underlying patterns without <it>a priori </it>surface classifications, were applied to our data.</p> <p>Results</p> <p>The three strongest caries patterns identified by PCA recaptured variation represented by DMFS index (correlation, r = 0.97), pit and fissure surface caries (r = 0.95), and smooth surface caries (r = 0.89). However, together, these three patterns explained only 37% of the variability in the data, indicating that <it>a priori </it>caries measures are insufficient for fully quantifying caries variation. In comparison, the first pattern identified by FA was strongly correlated with pit and fissure surface caries (r = 0.81), but other identified patterns, including a second pattern representing caries of the maxillary incisors, were not representative of any previously defined caries indices. Some patterns identified by PCA and FA were heritable (h²= 30-65%, p = 0.043-0.006), whereas other patterns were not, indicating both genetic and non-genetic etiologies of individual decay patterns.</p> <p>Conclusions</p> <p>This study demonstrates the use of decay patterns as novel phenotypes to assist in understanding the multifactorial nature of dental caries.</p
