Involvement of Acute Care Physical Therapists in Care Transitions for Older Adults Following Acute Hospitalization: A Cross-sectional National Survey
Authors: Falvey Jason R. , Burke Robert E. , Ridgeway Kyle J. , Malone Daniel J. , Forster Jeri E. , Stevens-Lapsley Jennifer E. 
Published: March 2018

Background and Purpose:
Recent evidence has suggested physical therapist involvement in care transitions after hospitalization is associated with reduced rates of hospital readmissions. However, little is known about how physical therapists participate in care transitions for older adults, the content of care communications, and the facilitators and barriers of implementing evidence-based care transition strategies into practice. Thus, the purpose of this article is to evaluate participation in care transition activities known to influence readmission risk among older adults, and understand perceptions of and barriers to participation in these activities.

Methods:
We developed a survey questionnaire to quantify hospital-based physical therapist participation in care transitions and validated it using cognitive interviewing. It was introduced to a cross-sectional national sample of physical therapists who participate in the Academy of Acute Care Physical Therapy electronic discussion board using a SurveyMonkey tool.

Results and Discussion:
More than 90% of respondents agreed they routinely recommended a discharge location and provided recommendations for durable medical equipment for patients at the time of hospital discharge. Respondents did not routinely initiate communication with therapists in other care settings, or follow up with patients to determine whether recommendations were followed. A majority of respondents agreed their facilities would not consider many key care transition activities to count as productive time.
This survey provides a novel insight into how hospital-based physical therapists participate in care transitions. Communications between rehabilitation providers across care settings are infrequent, even though those communications are recommended to help reduce readmissions. However, administrative barriers were elucidated in this study that may help explain lack of therapist involvement.

Conclusions:
Physical therapists' communications across health care setting about older adults discharging from acute care hospitalization are infrequent, but may represent a meaningful intervention target for future studies. Future research is needed to evaluate best practices for hospital-based physical therapists during care transitions.

AbstractKossow, AJ, DeChiara, TG, Neahous, SM, and Ebben, WP. Kinetic analysis of horizontal plyometric exercise intensity.J Strength Cond Res32(5): 1222–1229, 2018—Plyometric exercises are frequently performed as part of a strength and conditioning program. Most studies assessed the kinetics of plyometric exercises primarily performed in the vertical plane. The purpose of this study was to evaluate the multiplanar kinetic characteristics of a variety of plyometric exercises, which have a significant horizontal component. This study also sought to assess sex differences in the intensity progression of these exercises. Ten men and 10 women served as subjects. The subjects performed a variety of plyometric exercises including the double-leg hop, standing long jump, single-leg standing long jump, bounding, skipping, power skipping, cone hops, and 45.72-cm hurdle hops. Subjects also performed the countermovement jump for comparison. All plyometric exercises were evaluated using a force platform. Dependent variables included the landing rate of force development and landing ground reaction forces for each exercise in the vertical, frontal, and sagittal planes. A 2-way mixed analysis of variance with repeated-measures for plyometric exercise type demonstrated main effects for exercise type for all dependent variables (p≤ 0.001). There was no significant interaction between plyometric exercise type and sex for any of the variable assessed. Bonferroni-adjusted pairwise comparisons identified a number of differences between the plyometric exercises for the dependent variables assessed (p≤ 0.05). These findings should be used to guide practitioners in the progression of plyometric exercise intensity, and thus program design, for those who require significant horizontal power in their sport.
Evaluation of a Procedure for Determining the Converted Strength of Calcium Aluminate Cement Concrete
Authors: Adams Matthew P. , Lute Racheal D. , Moffatt Edward G. , Ideker Jason H. 
Published: March 2018

Abstract
There is renewed interest in North America for the use of calcium aluminate cement (CAC) in infrastructure repair because of its ability to gain strength rapidly even at low temperatures, the ability to customize its fresh workability, and its durability in adverse environments. Conversion of the hydration products of concrete where CAC is the only binder is a well-known phenomenon that is typically accompanied by strength loss, the rate and extent of which is dependent on the temperature history of the concrete, the w/cm, the cement content, and the concrete mixture design. An accelerated method of determining the converted strength of CAC concrete that is convenient for use in the field is presented. This test allows the samples to be cast in the field and left at ambient field temperatures for the first 24 hours; then the specimens are moved to the laboratory and placed in a water bath at 50°C to promote conversion. Robustness testing results are presented for the test method. The effects of the water to cement ratio, the initial (first 24 hours) curing temperature, the length of time before placing the specimens in the 50°C water bath, and the aggregate type are examined. The impact of the low replacement rates (up to 10 %) of finely ground limestone (FGLS) for CAC in concrete mixtures on converted concrete strengths was also studied. Results from testing showed that the majority of mixtures converted 48 hours after submersion in the 50°C water bath; however, differences in the initial curing temperature or aggregate type can delay conversion up to 11 days when specimens are cured following this procedure. Results also indicate that FGLS at replacement rates of 5 % and below in CAC systems may help increase the converted strength observed without reducing initial early strength gain.
Charpy Impact Test Methods for Cementitious Composites: Review and Commentary
Authors: Thomas Robert J. , Sorensen Andrew D. 
Published: March 2018

Abstract
Several researchers have recently employed the Charpy method to characterize the high strain rate mechanical strength of cementitious composites. This paper provides a critical review of existing applications of the Charpy method for impact testing of cementitious composites. Studies have employed various specimen sizes and geometries. Additionally, some studies have tested notched specimens while others have tested plain. Furthermore, varying methods of normalization result in results reported in a variety of incompatible units. The lack of consistency between studies limits the basis for comparison and the ability to validate results, which demonstrates a clear need for a standardized method for Charpy impact testing of cementitious composites. The authors recommend best practices based on sound mechanical principles and existing literature. Finally, the benefits and drawbacks of the Charpy method are discussed and its efficacy is compared with other prevalent methods for impact testing of cementitious composites.
Effect of Silver Addition on Mechanical Properties and Stress Corrosion Cracking in a Predeformed and Overaged 7055 Aluminum Alloy

Published: March 2018

Abstract
The effect of silver on mechanical properties and stress corrosion cracking (SCC) resistance in a predeformed and overaged 7055 aluminum alloy was investigated. The treatment consisted of solution treating the specimens and then applying 5 % plastic deformation (compression) before aging. The next operation was aging the specimens at 121°C for 24 hours and overaging them at 175°C for 10 hours. Properties of the alloys were investigated by mechanical testing, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and differential scanning calorimetry. Results show that the ultimate tensile strength (UTS) and yield tensile strength (YTS) for the silver-free alloy were 580 and 520 MPa, respectively, and increased to 594 and 567 MPa after the addition of 0.39 % silver. Moreover, the stress corrosion resistance increased ≥ 23 % after adding 0.2 % silver. It can be seen that the addition of silver to predeformed and overaged 7055 aluminum alloy slightly improves the UTS and YTS and increases resistance to SCC significantly. These improvements are due to the interrupting effect of silver on the continuity of magnesium-rich precipitates and the increasing copper absorption in the precipitates.

Abstract
High temperature and arc discharge are two important phenomena that occur in the electrical sliding processes. The extensive adhesive wear, due to high temperature, and arc erosive wear are two mechanisms that potentially cause severe wear of copper-carbon strips with electrical current. Herein, we describe a series of experiments done to better understand the high-temperature characteristics of a carbon strip rubbing against copper with electrical current passing from one to the other. During the experiments, the temperature of the copper-carbon strips was recorded and the wear volumes of carbon strips were measured. The results show that the carbon strip wear volumes are larger when electrical currents pass through the strips. To study how the temperature affects the wear of carbon strips, several wear tests were conducted at an elevated temperature both with and without electrical currents. The results show that adhesive wear is the main mechanism to cause severe wear of carbon strips.
Fast Ordered Sampling of DNA Sequence Variants
Authors: Greenberg Anthony J 
Published: March 2018

Abstract
Explosive growth in the amount of genomic data is matched by increasing power of consumer-grade computers. Even applications that require powerful servers can be quickly tested on desktop or laptop machines if we can generate representative samples from large data sets. I describe a fast and memory-efficient implementation of an on-line sampling method developed for tape drives 30 years ago. Focusing on genotype files, I test the performance of this technique on modern solid-state and spinning hard drives, and show that it performs well compared to a simple sampling scheme. I illustrate its utility by developing a method to quickly estimate genome-wide patterns of linkage disequilibrium (LD) decay with distance. I provide open-source software that samples loci from several variant format files, a separate program that performs LD decay estimates, and a C++ library that lets developers incorporate these methods into their own projects.
Tight Regulation of Srs2 Helicase Activity Is Crucial for Proper Functioning of DNA Repair Mechanisms

Published: March 2018

AbstractProper DNA damage repair is one of the most vital and fundamental functions of every cell. Several different repair mechanisms exist to deal with various types of DNA damage, in various stages of the cell cycle and under different conditions. Homologous recombination is one of the most important repair mechanisms in all organisms. Srs2, a regulator of homologous recombination, is a DNA helicase involved in DNA repair, cell cycle progression and genome integrity. Srs2 can remove Rad51 from ssDNA, and is thought to inhibit unscheduled recombination. However, Srs2 has to be precisely regulated, as failure to do so is toxic and can lead to cell death. We noticed that a very slight elevation of the levels of Srs2 (by addition of a single extra copy of the SRS2 gene) leads to hyper-sensitivity of yeast cells to methyl methanesulfonate (MMS, a DNA damaging agent). This effect is seen in haploid, but not in diploid, cells. We analyzed the mechanism that controls haploid/diploid sensitivity and arrived to the conclusion that the sensitivity requires the activity of RAD59 and RDH54, whose expression in diploid cells is repressed. We carried out a mutational analysis of Srs2 to determine the regions of the protein required for the sensitization to genotoxins. Interestingly, Srs2 needs the HR machinery and its helicase activity for its toxicity, but does not need to dismantle Rad51. Our work underscores the tight regulation that is required on the levels of Srs2 activity, and the fact that Srs2 helicase activity plays a more central role in DNA repair than the ability of Srs2 to dismantle Rad51 filaments.

Published: March 2018

Abstract
The ability to reproducibly target expression of transgenes to small, defined subsets of cells is a key experimental tool for understanding many biological processes. The Drosophila nervous system contains thousands of distinct cell types and it has generally not been possible to limit expression to one or a few cell types when using a single segment of genomic DNA as an enhancer to drive expression. Intersectional methods, in which expression of the transgene only occurs where two different enhancers overlap in their expression patterns, can be used to achieve the desired specificity. This report describes a set of over 2800 transgenic lines for use with the split-GAL4 intersectional method.

Published: March 2018

AbstractJohnsson et al. identify multiple genes affecting sociality-related behavior in chickens. They examine the genetic architecture of domestication in the chicken by studying pleiotropy and linkage in hypothalamus tissue. Statistical analyses of their eQTL data...The identification of genes affecting sociality can give insights into the maintenance and development of sociality and personality. In this study, we used the combination of an advanced intercross between wild and domestic chickens with a combined QTL and eQTL genetical genomics approach to identify genes for social reinstatement, a social and anxiety-related behavior. A total of 24 social reinstatement QTL were identified and overlaid with over 600 eQTL obtained from the same birds using hypothalamic tissue. Correlations between overlapping QTL and eQTL indicated five strong candidate genes, with the gene TTRAP being strongly significantly correlated with multiple aspects of social reinstatement behavior, as well as possessing a highly significant eQTL.

Published: March 2018

OBJECTIVES:
We sought to develop and validate a clinical calculator that can be used to quantify risk for appendicitis on a continuous scale for patients with acute abdominal pain.

METHODS:
The pediatric appendicitis risk calculator (pARC) was developed and validated through secondary analyses of 3 distinct cohorts. The derivation sample included visits to 9 pediatric emergency departments between March 2009 and April 2010. The validation sample included visits to a single pediatric emergency department from 2003 to 2004 and 2013 to 2015. Variables evaluated were as follows: age, sex, temperature, nausea and/or vomiting, pain duration, pain location, pain with walking, pain migration, guarding, white blood cell count, and absolute neutrophil count. We used stepwise regression to develop and select the best model. Test performance of the pARC was compared with the Pediatric Appendicitis Score (PAS).

RESULTS:
The derivation sample included 2423 children, 40% of whom had appendicitis. The validation sample included 1426 children, 35% of whom had appendicitis. The final pARC model included the following variables: sex, age, duration of pain, guarding, pain migration, maximal tenderness in the right-lower quadrant, and absolute neutrophil count. In the validation sample, the pARC exhibited near perfect calibration and a high degree of discrimination (area under the curve: 0.85; 95% confidence interval: 0.83 to 0.87) and outperformed the PAS (area under the curve: 0.77; 95% confidence interval: 0.75 to 0.80). By using the pARC, almost half of patients in the validation cohort could be accurately classified as at &lt;15% risk or ≥85% risk for appendicitis, whereas only 23% would be identified as having a comparable PAS of &lt;3 or &gt;8.

CONCLUSIONS:
In our validation cohort of patients with acute abdominal pain, the pARC accurately quantified risk for appendicitis.
Gray matter differences in the anterior cingulate and orbitofrontal cortex of young adults with Internet gaming disorder: Surface-based morphometry
Authors: Lee Deokjong , Park Jinsick , Namkoong Kee , Kim In Young , Jung Young-Chul 
Published: March 2018

Background and aims
Altered risk/reward decision-making is suggested to predispose individuals with Internet gaming disorder (IGD) to pursue short-term pleasure, despite long-term negative consequences. The anterior cingulate cortex (ACC) and the orbitofrontal cortex (OFC) play important roles in risk/reward decision-making. This study investigated gray matter differences in the ACC and OFC of young adults with and without IGD using surface-based morphometry (SBM).

Methods
We examined 45 young male adults with IGD and 35 age-matched male controls. We performed region of interest (ROI)-based analyses for cortical thickness and gray matter volume (GMV) in the ACC and OFC. We also conducted whole-brain vertex-wise analysis of cortical thickness to complement the ROI-based analysis.

Results
IGD subjects had thinner cortices in the right rostral ACC, right lateral OFC, and left pars orbitalis than controls. We also found smaller GMV in the right caudal ACC and left pars orbitalis in IGD subjects. Thinner cortex of the right lateral OFC in IGD subjects correlated with higher cognitive impulsivity. Whole-brain analysis in IGD subjects revealed thinner cortex in the right supplementary motor area, left frontal eye field, superior parietal lobule, and posterior cingulate cortex.

Conclusions
Individuals with IGD had a thinner cortex and a smaller GMV in the ACC and OFC, which are critical areas for evaluating reward values, error processing, and adjusting behavior. In addition, in behavioral control-related brain regions, including frontoparietal areas, they also had thinner cortices. These gray matter differences may contribute to IGD pathophysiology through altered risk/reward decision-making and diminished behavioral control.
