X-ray Fractographic Study on Fracture Surface of New Light Metal
Authors: Matsuoka Hideaki , Hirose Yukio , Takahashi Shigenobu , Yajima Zenjiro , Kishi Yoichi 
Published: July 2019

Abstract
New materials in the Al-Zn-Mg-Cu-La alloy system have been proposed for improving corrosion resistance in a study by Kishi et al, because Lanthanum, La, has a storage capability for hydrogen. Hydrogen is a problem in the stress corrosion cracking (SCC) growth mechanism. Zinc, Zn, Magnesium, Mg, and Copper, Cu, in the alloy have influenced the extrusion, strength and other properties; however, in the case of putting this material to use, it is also necessary to evaluate it from the viewpoint of fracture mechanics. The stress intensity factor, K, obtained from fracture mechanics is a necessary parameter for the evaluation of various materials.
The first part of this study deals with the measurement of fatigue crack growth in the Al-Zn-Mg-Cu-La alloy system. The second part evaluates the fracture surface obtained from tests of these materials by the application of x-ray fractography.
Residual Stress in Ion Implanted Titanium Nitride Studied by Parallel Beam Glancing Incidence X-ray Diffraction
Authors: Geist Daniel E. , Perry Anthony J. , Tireglio James R. , Valvoda Vaclav , Rafaja David 
Published: July 2019

Abstract
Ion implantation is known to increase the lifetime of cutting tools. Current theories are the increase in lifetime is caused by an increase in the residual stress, or by work hardening of the surface associated with the implantation. In this work the effect of ion implantation on the residual stress in titanium nitride coatings made by the standard industrial methods of chemical and physical vapor deposition (CVD and PVD) is studied. It is found in the as-received condition (unimplanted), the residual stress levels are near zero for CVD materials and highly compressive, of the order of 6 GPa, for PVD materials. Ion implantation has no effect on the residual stress: in the coatings made by CVD. Nitrogen does increase the compressive residual stress by some 10% in the near surface regions of PVD coatings, while nickel-titanium dual metal ion implantation does not have any effect. It appears that the lifetime increase is not associated with residual stress effects.
Development of Bone-Lead Reference Materials for Validating In Vivo Xrf Measurements
Authors: Parsons Patrick J. , Zong Yan Y. , Roland Matthews M. 
Published: July 2019

Summary
A number of biological reference materials (RM) have been prepared in our laboratory specifically for validating analytical methods for the determination of Pb in biological matrices (e.g. blood, urine, liver, and bone). The RM's were developed using animal (goats and cows) that are routinely dosed with lead acetate to produce proficiency test samples for blood lead (and erythrocyte protoporphyrin). In cases where an animal becomes injured or infirm, the veterinarian in charge may recommend that the animal be euthanized. In such cases, samples of bone, brain, liver, and other tissues containing lead are removed at autopsy.
Currently, we have collected bone samples from nine goats and one cow that were dosed with lead over periods ranging from 1 to 10 years, During the autopsy, the epiphyses (bone joints) are separated from each long bone. Skin, muscle, and other adhering tissues are dissected or scraped from each bone. Bone marrow is also removed. All bare bones are currently stored at -70°C until analyses for Pb are conducted.
The only certified reference materials for bone Pb are those available from the National Institute for Standards and Technology (NIST), Gaithersburg, MD. Standard Reference Material (SRM) 1486 Bone Meal has a certified Pb concentration of only 1.335 μg/g. This is close to normal for humans, but is too low to be of practical use for in vivo X-Ray Fluorescence (XRF) equipment, SRM 1400 Bone Ash has a certified Pb concentration of 9.07 μg/g. Neither SRM is optimal for validating in vivo XRF equipment, but they are both very useful in validating other analytical methods for bone Pb such as Graphite Furnace Atomic Absorption Spectrometry (GFAAS).
We have developed an accurate, precise, and sensitive method for determining Pb in bone using GFAAS with Zeeman background correction. Using this method, we have analyzed the animal bones for Pb. Bone samples were divided into smaller pieces using a diamond-disc saw, freeze dried, and homogenized in a tantalum ball mill. Samples of bone powder were digested in nitric acid using a closed vessel microwave digestion system. Lead was determined using aqueous Pb standards in a chemical modifier optimized for the bone matrix. The method was validated using NIST SRM Bone Meal and Bone Ash. The detection limit is 0.6 μg/g based on 3 SD. Results for Pb in our animal bone range from approximately 5 to 50 μg/g dry weight. The results indicate that the intact bare bones would be excellent candidates for interlaboratory studies of in vivo XRF measurements of bone Pb. They are stable, well-characterized, easily transported between sites, and cover the clinically relevant range of bone lead concentrations likely to be encountered in the field. It is proposed that these materials be circulated as part of an interlaboratory comparison to interested centers using in vivo XRF After the XRF analyses, the bone samples will be analyzed for Pb by GFAAS for comparison purposes.
Characterization of the Tin Diffusion into Float Glass Using Glancing Angle X-Ray Characterization
Authors: LaPuma P. J. , Snyder R. L. , Zdzieszynski S. , Brückner R. 
Published: July 2019

Abstract
Using x-ray reflectometry the surface of float glass samples of different Fe content and thickness were studied. The patterns needed an oil/water layer to be modeled correctiy. The maximum Sn concentration was found to reside in the top 10-20Å of the material and the Sn concentration decreased into the bulk. It was also found that increased Fe content decreased the Sn concentrations in the surface and bulk of the glass.
FPXRF, EDXRF and ICP Comparison of Pb Contaminated Soils From Leadville, Colorado
Authors: Kuharic C.A. , Cole W.H. 
Published: July 2019

Abstract
Field portable x-ray fluorescence (FPXRF) has been used as a tool in the environmental industry to characterize metals contaminated soils for about 10 years. Initially, due to the level of sophistication of the equipment (ambient temperature detectors and empirical calibration spectral processing), and the complexity of soil matrices, it was generally believed that the instrumentation could only produce semiquantitative data. As the level of instrument sophistication increased (cooled solid-state detectors and Fundamental Parameters), that perception of FPXRF changed. However, not all users have access to the latest, state-of-the-art instrumentation. Work performed at Leadville, Colorado provides an example of how properly used older instrumentation can produce data of good quality (Kuharic, et al., 1993).

Published: July 2019

Background and Purpose—
There is contradictory evidence on the impact of the stroke side (hemisphere) on outcomes. We investigated any effect modification by laterality on stroke patients’ outcomes in recent endovascular trials.

Methods—
Individual patient-level data were combined in this meta-analysis of all patients included in randomized trials comparing endovascular thrombectomy predominantly done with stent retrievers with standard care in anterior circulation ischemic patients with stroke (HERMES [Highly Effective Reperfusion Using Multiple Endovascular Devices] Collaboration). We stratified the 90-day functional outcome assessed by ordinal analysis of the modified Rankin Scale according to the stroke side of patients treated with endovascular therapy versus standard care, adjusted for important prognostic variables.

Results—

The meta-analysis included 1737 patients (871 right hemispheric strokes and 866 left hemispheric) from 7 trials. Baseline median National Institutes of Health Stroke Scale scores were significantly higher in left (20) versus right (16) hemispheric strokes (
P
<0.001). Other clinical and radiological baseline characteristics were similar. The beneficial response to endovascular therapy assessed by 90-day modified Rankin Scale shift was not modified by the side of the stroke. There were no significant differences between right and left hemispheric stroke in the 90-day functional outcome (modified Rankin Scale score ≤2; 40.7% [95% CI, 37.4%–44.1%] versus 37.6% [95% CI, 37.4%–44.1%];
P
=0.19), median final infarct volumes (45 versus 39.5 mL,
P
=0.51), nor 90-day mortality (15.1% vs 16.8%,
P
=0.31).

Conclusions—
Stroke side was not a prognostic factor and did not modify the treatment effect among patients treated in the endovascular or control groups in recent endovascular thrombectomy trials.
Garments of Shame, Garments of War: Clothing Imagery in 1 Maccabees 1:25-28, 14:9
Authors: Livneh Atar 
Published: July 2019

AbstractTwo poetic passages in 1 Maccabees depict historical circumstances via the use of apparel. 14:9 portrays the young men as wearing “glories and garments of war” as a marker of the peace and prosperity characterizing Simon’s reign. These contrast with the “shame” that shrouds the people following Antiochus Epiphanes’ desecration of the temple in 1:28. This paper explores the biblical background of the dress imagery, suggesting that the Maccabean author transformed the “robe of righteousness” in Isa 61:10 into “garments of war” on the basis of a gezerah shava with Isa 59:17. The biblical metaphor of “being clothed with shame” in 1 Macc 1:28, on the other hand, refers to the “putting on of mourning dress”—a practice also alluded to in v. 26.

Abstract
Time is a valuable but limited resource, and animals’ survival depends on their ability to carefully manage the amount of time they allocate to each daily activity. While existing research has examined the ecological factors affecting animals’ activity budgets, the impact of anthropogenic factors on urban-dwelling animals’ time budgets remains understudied. Here we collected data through focal animal sampling from three groups of rhesus macaques in Northern India to examine whether interactions with humans decrease macaques’ resting and social time (time constraints hypothesis), or whether, by contrast, foraging on anthropogenic food, that is potentially high in calories, leads macaques to spend more time resting and in social interactions (free time hypothesis). We found that macaques who interacted more frequently with people spent significantly less time resting and grooming, supporting the time constraints hypothesis. We argue that these time constraints are likely caused by the unpredictability of human behaviour.
The Degree of Stress in Patients With Empty Nose Syndrome, Compared With Chronic Rhinosinusitis and Allergic Rhinitis
Authors: Kim Chang Hoi , Kim Jooyeon , Song Ji Ah , Choi Gil Soon , Kwon Jae Hwan 
Published: July 2019

Background: Depression is a mental health disease of growing public health concern because depressive mood affects the sufferer’s daily life and is also associated with productivity decline. Depression that is caused by other diseases or substances is referred to as secondary depression, which is an important distinction because curing the underlying cause could subsequently regulate depressive mood. Empty nose syndrome (ENS), also known as “paradoxical obstruction of the nose,” is a condition in which the major symptom is difficulty breathing, despite having sufficient breathing space in the nose. Empty nose syndrome has been increasing in prevalence in Korea. We found that patients with this ENS have a tendency toward depressive mood, which can escalate so far as to lead to suicide attempts. Thus, herein, we aimed to investigate the psychological burden on patients with ENS. Methods: We divided patients into 4 groups: ENS (group A), chronic rhinosinusitis with polyp (CRS c polyp, group B), chronic rhinosinusitis without polyp (CRS s polyp, group C), and allergic rhinitis (AR, group D). We estimated and compared Beck Depression Inventory (BDI) scores among the 4 groups, and we investigated the relationship between depression index and nasal cavity area in patients with ENS. Results: The ENS group (A) had depression prevalence of 71% with varying severity, which was much higher than group B (19%), group C (15%), and group D (27%). The correlation between nasal cavity volume and BDI score for the ENS group was not statistically significant. Conclusion: The degree and severity of depression in patients with ENS was higher than in patients with CRS or AR. Furthermore, there was no relationship between depression severity and nasal cavity volume in the patients with ENS. Thus, physicians should be careful not to dismiss the accompanying mental health problems of patients with ENS.

Impact of State Laws Governing Physical Education on Attendance Among US High School Students, 2003 to 2017
Authors: An Ruopeng , Ji Mengmeng , Clarke Caitlin , Guan Chenghua 
Published: July 2019

Purpose: This study assessed the influence of state laws governing physical education (PE) on weekly PE class attendance among US high school students. Design: Cross-sectional. Setting: 2003 to 2017 US national Youth Risk Behavior Survey (YRBS). Participants: A total of 533 468 high school students. Measures: Data on state laws governing PE came from National Cancer Institute’s Classification of Laws Associated with School Students (CLASS). Eight distinct state PE policies were scored, with higher scores denoting stronger laws. Analysis: Individual-level YRBS data were merged with CLASS data based on students’ residential state and survey year. State fixed-effect negative binomial regressions were performed, adjusting for individual-level characteristics and YRBS survey design. Results: A 1-score increase in state laws governing PE class time, staffing for PE, joint use agreement for physical activity, assessment of health-related fitness, and PE curriculum was associated with an increase in weekly PE attendance by 0.30, 0.28, 0.22, 0.20, and 0.13 days ( P < .001), respectively. In contrast, a 1-score increase in state laws governing moderate-to-vigorous-intensity physical activity time in PE, PE proficiency, and recess time was associated with a reduction in weekly PE attendance by 0.25, 0.15, and 0.09 days ( P < .001), respectively. The effects of most state PE policies on PE class attendance were larger among girls than boys. Conclusion: State PE policies differentially impacted US high school students’ PE class attendance, with larger effects on female students.

Published: July 2019

Introduction: Carotid angioplasty and stenting (CAS) represents an effective procedure for treating carotid artery disease. The acute in-stent thrombosis is an extremely rare complication of CAS especially when it occurs postprocedurally during the first 24 hours. Improper antiplatelet therapy or poor response to antiplatelet medications is known to be associated with a higher risk of in-stent thrombosis during early postprocedural period following a successful intervention. Material and Methods: A patient who experienced acute carotid in-stent thrombosis in early postprocedural period is described. He had been taking dual antiplatelet therapy for 2 weeks before undergoing a successful CAS. Moreover, pharmacogenetics studies showed the patient to be a clopidogrel ultrarapid metabolizer, which theoretically confers hyperresponsivity to medication. Alongside the report itself, a brief literature review of relevant sources pertinent to the case has been conducted. Results: According to the available literature, this is the first case report describing an ultrarapid clopidogrel metabolizer who underwent an uneventful CAS but experienced acute carotid in-stent thrombosis in early postprocedural period. A rescue procedure included an endovascular intervention consisting of thrombectomy and local alteplase application, followed by postprocedural administration of intravenous eptifibatide. At discharge, patient’s dual antiplatelet therapy included ticagrelor instead of clopidogrel. Conclusion: Acute carotid in-stent thrombosis is a highly unexpected complication of CAS and can occur despite ultrarapid clopidogrel metabolism trait.
Asymptomatic carotid stenosis and concomitant silent brain infarctions
Authors: Rudolph Claudina , Eldrup Nikolaj 
Published: July 2019

Objectives This review aims to clarify (1) the definition of silent brain infarct (SBI), (2) the diagnostic criteria of SBI using magnetic resonance imaging (MRI), (3) the prevalence of patients with asymptomatic carotid stenosis and SBI based on MRI assessment, (4) the association of SBI and asymptomatic carotid stenosis and the risk of stroke compared to patients without SBI, (5) the association between development of dementia/cognitive impairment in people with asymptomatic carotid stenosis and SBI, and (6) the evidence for treating patients with carotid stenosis and SBI. Methods A systematic search of PubMed and Scopus including all studies published from 2000 to 2018 and written in English. Results No consensus of the definition and diagnostic criteria for SBI was found. The prevalence of SBI in asymptomatic carotid patients is 17–33.3%. SBI is a significant risk factor for future stroke, OR 4.6 (95% CI: 3.0–7.2; p < 0.0001). One substudy showed that immediate CEA is beneficial compared to delayed CEA in these patients, showing a 45% reduction in annual stroke rate from 1.5%/year to 0.7%/year. Conclusion This review emphasizes the need to standardize the definition and diagnostic criteria of SBI on MRI. Current evidence suggests an increased risk and a small potential benefit of offering carotid endarterectomy to patient with silent brain infarct. Prospective studies are warranted to elucidate these issues further.
Influence of psychological factors on patient-reported upper extremity disability
Authors: Cheng Homan , Novak Christine B. , Veillette Christian , von Schroeder Herbert P. 
Published: July 2019

Disability reflects physical impairment and the influence of psychosocial factors. We investigated the relationship between disability and psychosocial factors in patients with upper extremity pathology. Ninety-two patients at a hand clinic were evaluated to assess disability, pain intensity, health status and psychosocial factors (pain catastrophizing, depression). Statistical analyses evaluated the relationships among disability and patient and psychosocial factors. Moderate levels of disability from all types of pathology were reported and associated with pain catastrophizing, pain and depression. Health status Short Form 36 domains were not correlated with disability as determined by Disabilities of the Arm, Shoulder and Hand (DASH) scores. A strong correlation was found between DASH and QuickDASH scores, but the QuickDASH scored significantly higher by 4 points. Pain catastrophizing was the strongest predictor of disability and explained 59% and 63% of variation in disability scores. Independent of pathology, those patients experiencing psychosocial issues, as well as demographic factors (i.e. employment status and age), were more likely to have disability with hand conditions and surgical procedures. We conclude from this study that psychological factors affect patient-reported outcomes. Level of evidence: IV

Authors: Abraham Sinu Bessy , Arunachalam Siddharth , Zhong Alex , Agrawal Pratik , Cohen Ohad , McMahon Chantal M. 
Published: July 2019

Background: Most standalone real-time continuous glucose monitoring (RT-CGM) systems provide predictive low and high sensor glucose (SG) threshold alerts. The durations and risk of low and high SG excursions following Guardian™ Connect CGM system predictive threshold alerts were evaluated. Methods: Continuous glucose monitoring system data uploaded between January 2, 2017 and May 22, 2018 by 3133 individuals using multiple daily injections (MDIs) or continuous subcutaneous insulin infusion (CSII) therapy were deidentified and retrospectively analyzed. Glucose excursions were defined as SG values that went beyond a preset low or high SG threshold for ≥15 minutes. For a control group, thresholds were based on the median of the low SG threshold limit (70 mg/dL) and the high SG threshold limit (210 mg/dL) preset by all system users. During periods when alerts were not enabled, timestamps were identified when a predictive alert would have been triggered. The time before low horizon was 17.5 minutes and the time before high horizon was 15 minutes, of all users who enabled alerts. Excursions occurring after a low SG or high SG predictive alert were segmented into prevented, ≤20, 20-60, and >60 minutes. Results: Excursions were prevented after 59% and 39% of low and high SG predictive alerts, respectively. The risk of a low or high excursion occurring was 1.9 ( P < 0.001, 95% CI, 1.88-1.93) and 3.3 ( P < 0.001, 95% CI, 3.20-3.30) times greater, respectively, when alerts were not enabled. Conclusions: The predictive alerts of the RT-CGM system under study can help individuals living with diabetes prevent some real-world low and high SG excursions. This can be especially important for those unable to reach or maintain glycemic control with basic RT-CGM or CSII therapy.
