Healthcare Industry Injuries by Patient Contact Status in Kentucky, 2012–2014

Objectives The healthcare industry continues to have a high number of reported injuries. The purpose of this study was to characterize healthcare industry injuries by patient contact status, identify the occupations associated with healthcare injuries by patient contact status, and determine healthcare injury rates by occupation to gain a better understanding of healthcare industry-compensated injuries and better target safety practices and programs in the healthcare industry. Methods Kentucky healthcare industry workers’ compensation first reports of injuries from calendar years 2012–2014 were categorized into injuries involved in direct patient contact versus injuries without direct patient contact using narrative text analysis. Injury numbers and rates were calculated for a number of data variables. Results Healthcare injuries without direct patient contact (55% of all first reports of injuries) occurred more frequently among older workers (45 years old and older [51%]), in “other” occupations such as housekeeping and maintenance (28%), and as a result of falls/slips/trips (39%) and sprains/tears (38%). In contrast, a higher percentage of healthcare injuries involving direct patient contact occurred among workers younger than 35 years (48%), in healthcare support occupations (50%), and resulting from sprains/tears (66%) and lifting/handling (52%), compared with those without direct patient contact. Conclusions Findings from this study can better target the need for new and/or additional specific workplace safety training, especially in the healthcare support and nursing occupations with and without patient contact.
Anatomical features associated with venous congestion in DIEP flap using CT angiography with three-dimensional reconstruction

Aim: Computed tomography angiography (CTA) using three-dimensional (3D) virtual reconstruction has been increasingly used in planning deep inferior epigastric artery perforator (DIEP) breast reconstruction. Although the most common complication associated with this surgery is diffuse venous congestion, its origin remains unclear. The aim of this study was to assess the anatomical characteristics of the anterior abdominal wall vessels that could predict venous congestion, using CTA with 3D virtual reconstruction. Methods: A retrospective case-control study was conducted and a total of 169 DIEP flaps were reviewed. An abdominal CTA with 3D virtual reconstruction was analyzed with regard to anatomical features of the abdominal wall vessels. Seven venous congestive cases were identified. For each case, 3 controls that had not exhibited any vascular complications were randomly selected. Results: The global venous congestion rate was 4.14%. No statistically significant differences were found between the groups’ superficial inferior epigastric vein (SIEV) diameter (P = 0.915), number of branches of SIEV (P = 0.371), number of perforators per flap (P = 0.255), flap subcutaneous tissue thickness (P = 0.652), direct communications between SIEV-perforators (P = 0.418), and communications of both SIEVs across the abdominal midline (P = 0.371). Conclusion: The present study provided ABSTRACT
Social Interactions in Large Networks: A Game Theoretic Approach

This article studies estimation of social interactions in a large network game, where all observations come from one single equilibrium of a network game with asymmetric information. Simple assumptions about the structure are made to establish the existence and uniqueness of the equilibrium. I show that the equilibrium strategies satisfy a network decaying dependence condition requiring that dependence between two players' decisions decay with their network distance, which serves as the basis for my statistical inference. Moreover, I establish identification and propose a computationally feasible and efficient estimation method, which is illustrated by an empirical application of college attendance.
Slowing gait and risk for cognitive impairment

Objective: To identify the shared neuroimaging signature of gait slowing and cognitive impairment. Methods: We assessed a cohort of older adults (n = 175, mean age 73 years, 57% female, 65% white) with repeated measures of gait speed over 14 years, MRI for gray matter volume (GMV) at year 10 or 11, and adjudicated cognitive status at year 14. Gait slowing was calculated by bayesian slopes corrected for intercepts, with higher values indicating faster decline. GMV was normalized to intracranial volume, with lower values indicating greater atrophy for 10 regions of interest (hippocampus, anterior and posterior cingulate, primary and supplementary motor cortices, posterior parietal lobe, middle frontal lobe, caudate, putamen, pallidum). Nonparametric correlations adjusted for demographics, comorbidities, muscle strength, and knee pain assessed associations of time to walk with GMV. Logistic regression models calculated odds ratios (ORs) of gait slowing with dementia or mild cognitive impairment with and without adjustment for GMV. Results: Gait slowing was associated with cognitive impairment at year 14 (OR per 0.1 s/y slowing 1.47; 95% confidence interval 1.04–2.07). The right hippocampus was the only region that was related to both gait slowing (ρ = −0.16, p = 0.03) and cognitive impairment (OR 0.17, p = 0.009). Adjustment for right hippocampal volume attenuated the association of gait slowing with cognitive impairment by 23%. Conclusions: The association between gait slowing and cognitive impairment is supported by a shared neural substrate that includes a smaller right hippocampus. This finding underscores the value of long-term gait slowing as an early indicator of dementia risk.
Ground-Based Remote Sensor Observations during PROBE in the Tropical Western Pacific

Abstract From 6 January to 28 February 1993, the second phase of the Pilot Radiation Observation Experiment (PROBE) was conducted in Kavieng, Papua New Guinea. Routine data taken during PROBE included radiosondes released every 6 h and 915-MHz Wind Profiler—Radio Acoustic Sounding System (RASS) observations of winds and temperatures. In addition, a dual-channel Microwave Water Substance Radiometer (MWSR) at 23.87 and 31.65 GHz and a Fourier Transform Infrared Radiometer (FTIR) were operated. The FTIR operated between 500 and 2000 cm-1 and measured some of the first high spectral resolution (1 cm-1) radiation data taken in the Tropics. The microwave radiometer provided continuous measurements within 30-s resolution of precipitable water vapor (PWV) and integrated cloud liquid, while the RASS measured virtual temperature profiles every 30 min. In addition, occasional lidar soundings of cloud-base heights were available. The MWSR and FTIR data taken during PROBE were compared with radiosonde data. Significan.
Nitrogen Addition Shapes Soil Phosphorus Availability in Two Reforested Tropical Forests in Southern China

Scant information is available on how soil phosphorus (P) availability responds to atmospheric nitrogen (N) deposition, especially in the tropical zones. This study examined the effect of N addition on soil P availability, and compared this effect between forest sites of contrasting land‐use history. Effects of N addition on soil properties, litterfall production, P release from decomposing litter, and soil P availability were studied in a disturbed (reforested pine forest with previous understory vegetation and litter harvesting) and a rehabilitated (reforested mixed pine/broadleaf forest with no understory vegetation and litter harvesting) tropical forest in southern China. Experimental N‐treatments (above ambient) were the following: Control (no N addition), N50 (50 kg N ha−1 yr−1), and N100 (100 kg N ha−1 yr−1). Results indicated that N addition significantly decreased soil P availability in the disturbed forest. In the rehabilitated forest, however, soil P availability was significantly increased by N addition. Decreases in soil P availability may be correlated with decreases in rates of P release from decomposing litter in the N‐treated plots, whereas the increase in soil P availability was correlated with an increase in litterfall production. Our results suggest that response of soil P availability to N deposition in the reforested tropical forests in southern China may vary greatly with temporal changes in tree species composition and soil nutrient status, caused by different land‐use practices.
Intracoronary beta-radiation to reduce restenosis after balloon angioplasty and stenting; the Beta Radiation In Europe (BRIE) study.

AIMS The BRIE trial is a registry evaluating the safety and performance of (90)Sr delivered locally (Beta-Cath TM system of Novoste) to de-novo and restenotic lesions in patients with up to two discrete lesions in different vessels. METHODS AND RESULTS In total, 149 patients (175 lesions) were enrolled; 62 treated with balloons and 113 with stents. The restenosis rate, the minimal luminal diameter and the late loss were determined in three regions of interest: (a) in a subsegment of 5mm containing the original minimal luminal diameter pre-intervention termed target segment; (b) the irradiated segment, 28 mm in length, and (c) the entire analysed segment, 42 mm in length, termed the vessel segment. Binary restenosis was 9.9% for the target segment, 28.9% for the irradiated segment, and 33.6% for the vessel segment. These angiographic results include 5.3% total occlusions. Excluding total occlusions binary restenosis was 4.9%, 25% and 29.9%, respectively. At 1 year the incidence of major adverse cardiac events placed in a hierarchical ranking were: death 2%, myocardial infarction 10.1%, CABG 2%, and target vessel revascularization 20.1%. The event-free survival rate was 65.8%. Non-appropriate coverage of the injured segment by the radioactive source termed geographical miss affected 67.9% of the vessels, and increased edge restenosis significantly (16.3% vs 4.3%, P=0.004). It accounted for 40% of the treatment failures. CONCLUSION The results of this registry reflect the learning process of the practitioner. The full therapeutic potential of this new technology is reflected by the restenosis rate at the site of the target segment. It can only be unravelled once the incidence of late vessel occlusion and geographical miss has been eliminated by the prolonged use of thienopyridine, the appropriate training of the operator applying this new treatment for restenosis prevention, and the use of longer sources.
A New Porous Hybrid Material Derived From Silica Fume and Alginate for Sustainable Pollutants Reduction

In this work a new mesoporous adsorbent material obtained from a natural, high abundant raw material and a high volume industrial by-product is presented. The material is consolidated by the gelling properties of alginate and by decomposition of sodium-bicarbonate controlled porosity at low temperatures (70–80°C) at different scale lengths. The structural, thermal, and morphological characterization shows that the material is a mesoporous organic-inorganic hybrid. The material is tested as adsorbent, showing high performances. Methylene blue, used as model pollutant, can be adsorbed and removed from aqueous solutions even at a high concentration with efficiency up to 94%. By coating the material with a 100 nm thin film of titania, good photodegradation performance (more than 20%) can be imparted. Based on embodied energy and carbon footprint of its primary production, the sustainability of the new obtained material is evaluated and quantified in respect to activated carbon as well. It is shown that the new proposed material has an embodied energy lower than one order of magnitude in respect to the one of activated carbon, which represents the gold standards. The versatility of the new material is also demonstrated in terms of its design and manufacturing possibilities In addition, this material can be printed in 3D. Finally, preliminary results about its ability to capture diesel exhaust particulate matter are reported. The sample exposed to diesel contains a large amount of carbon in its surface. At the best of our knowledge, this is the first time that hybrid porous materials are proposed as a new class of sustainable materials, produced to reduce pollutants in the wastewaters and in the atmosphere.
Novel TEO-based Gammatone features for environmental sound classification

In this paper, we propose to use modified Gammatone filterbank with Teager Energy Operator (TEO) for environmental sound classification (ESC) task. TEO can track energy as a function of both amplitude and frequency of an audio signal. TEO is better for capturing energy variations in the signal that is produced by a real physical system, such as, environmental sounds that contain amplitude and frequency modulations. In proposed feature set, we have used Gammatone filterbank since it represents characteristics of human auditory processing. Here, we have used two classifiers, namely, Gaussian Mixture Model (GMM) using cepstral features, and Convolutional Neural Network (CNN) using spectral features. We performed experiments on two datasets, namely, ESC-50, and UrbanSound8K. We compared TEO-based coefficients with Mel filter cepstral coefficients (MFCC) and Gammatone cepstral coefficients (GTCC), in which GTCC used mean square energy. Using GMM, the proposed TEO-based Gammatone Cepstral Coefficients (TEO-GTCC), and its score-level fusion with MFCC gave absolute improvement of 0.45 %, and 3.85 % in classification accuracy over MFCC on ESC-50 dataset. Similarly, on UrbanSound8K dataset the proposed TEO-GTCC, and its score-level fusion with GTCC gave absolute improvement of 1.40 %, and 2.44 % in classification accuracy over MFCC. Using CNN, the score-level fusion of Gammatone spectral coefficient (GTSC) and the proposed TEO-based Gammatone spectral coefficients (TEO-GTSC) gave absolute improvement of 14.10 %, and 14.52 % in classification accuracy over Mel filterbank energies (FBE) on ESC-50 and UrbanSond8K datasets, respectively. This shows that proposed TEO-based Gammatone features contain complementary information which is helpful in ESC task.
Novel Minimally Invasive Wireless Nanotechnology Neuromodulation System in theManagement of Chronic Pain Syndromes

Chronic back pain has been reported to plague over 90 million Americans, with a large percentage of inflicted forced to manage their pain with addictive and dangerous opioid therapies as their only long-term remedy. Spinal cord stimulation (SCS) has been proven to be a reliable adjunctive therapy for over 40 years to assist in pain management for those with failed back surgery syndrome (FBSS), however limitations in waveforms to prevent plasticity as well as the need for expensive and highly invasive surgery have limited the adoption of neurostimulation. Recent advancements in nanotechnology enabled minimally invasive procedural approaches that both lower tissue trauma for the patient, and provide a lower cost option for the combination management of pain. Wireless neuromodulation leveraging advancements in nanotechnology for the relief of chronic pain in multiple trials and case studies. A miniature stimulator device with microelectronics is placed by percutaneous methods at targeted nerves and controlled by a wireless power generator outside the patients’ body providing pain relief for a number of conditions like chronic back pain secondary to failed back surgery, facial pain, and post-herpes zoster neuralgia. Device migrations occurred in a small number of patients and securing the device in-situ has been a topic for further refinements. Devices with nanotechnology materials and wireless control have better efficiency because of improved neural-electric interface (replacing the more popular term, the brain-machine-interface). These techniques offer less invasive, less expensive and yet improved outcomes with better cosmetic results and safety profiles. Wider applications of the technology, however, require further studies on more patients and metrics for outcome evaluations.
In Vitro Effect of Apigenin and Danshen in Tibial Dyschondroplasia Through Inhibition of Heat-Shock Protein 90 and Vascular Endothelial Growth Factor Expressions in Avian Growth Plate Cells

SUMMARY Tibial dyschondroplasia (TD) is one of the common skeletal abnormalities in fast-growing birds, and it is characterized by nonvascularized, unmineralized, and nonviable cartilage in the tibial growth plate that fails to form bone. The aim of this study was to check the in vitro effect of apigenin and danshen on heat-shock protein 90 (Hsp90) and vascular endothelial growth factor (VEGF) expressions in avian growth plate cells treated with sublethal concentration of thiram. Initially, chondrocytes from chicken growth plates were isolated on culturx ed medium with and without various concentration of thiram to determine the sublethal dose. Then, to check the effect of apigenin and danshen, the chondrocytes were treated first with a sublethal (2.5 μM) concentration of thiram and then with different doses (10, 20, 40, and 80 μM) of apigenin and danshen. The mRNA expression levels of Hsp90 and VEGF genes were evaluated by quantitative reverse transcription polymerase chain reaction (RT-qPCR). The results showed that the expression levels of Hsp90 and VEGF mRNA transcripts were increased significantly (P < 0.05) in thiram-treated chondrocytes culture medium up to 1.5-fold, whereas apigenin and danshen therapy to chondrocytes in culture medium significantly (P < 0.05) reduced the Hsp90 and VEGF expression levels. In conclusion, up-regulation of both (Hsp90 and VEGF) genes and damage to chondrocytes in culture medium caused by thiram can be restored by using apigenin and danshen. Therefore, apigenin and danshen therapies are suggested and encouraged as a promising approach to control TD in broiler chickens.
Understanding the behavioral intention to play Austronesian learning games: from the perspectives of learning outcome, service quality, and hedonic value

ABSTRACT Although ubiquitous learning is a novel and creative teaching approach, two key issues inhibit its success overall: a lack of appropriate learning strategies regarding learning objectives, and ineffective learning tools for receiving knowledge regarding the chosen subjects. To address these issues, we develops and designs a game-based educational app and an object-linked knowledge environment in order to help learners learn about Taiwan’s Austronesian culture. 70 fifth-grade students are split into experimental and control groups to determine whether there are significant learning differences. For the experimental group, we use a questionnaire survey to assess students’ learning condition and to measure their willingness to continue to use this app. The questionnaire examines mobile learning from the perspectives of service quality, hedonic value,and certain control variables. Service quality reliability is found to be the key factor driving learners’ willingness to use the system. The perception of hedonic value also has significant influence on learners’ willingness. The control variable of subjective norm is found to be beneficial in encouraging learners to use the system, thus affecting and increasing learners’ willingness. We conclude that in an outdoor object-linked knowledge environment, students learn more effectively when the activities involve the use of an educational app.
Risk, Inequality, Insurance, and Welfare

equity. I explore the relationship between our attitudes about risk and our beliefs about distributive justice. The notion that there is a deep relationship between risk and inequality is not a new one; discussions of the topic date at least from Harsanyi’s work on the subject in the 1950s. Harsanyi argued that the cardinal utility functions appearing in the theory of decisions under uncertainty and the cardinal utility functions in welfare economics should be one and the same (I will refer to this as the Harsanyi framework). In this paper I review Harsanyi’s argument, as well as Rawls’s theory of justice as fairness, which (despite reaching very dierent conclusions) also links ideas of risk and inequality. I extend this parallel by noting that wealth redistribution can be viewed as an insurance contract from the perspective of the original position, and I explore whether observed levels of inequality in America appear to be consistent with the level of insurance one would demand from the perspective of the original position. I will consider a potential objection to Harsanyi’s view| that individual utilities are additively separable across possible outcomes, while social welfare is not additively separable across individual utilities. I will argue that this objection in fact poses no theoretical diculty for the Harsanyi framework, though it may make empirical evaluation of
Outdoor Air Pollution, Preterm Birth, and Low Birth Weight: Analysis of the World Health Organization Global Survey on Maternal and Perinatal Health

Background: Inhaling fine particles (particulate matter with diameter ≤ 2.5 μm; PM2.5) can induce oxidative stress and inflammation, and may contribute to onset of preterm labor and other adverse perinatal outcomes. Objectives: We examined whether outdoor PM2.5 was associated with adverse birth outcomes among 22 countries in the World Health Organization Global Survey on Maternal and Perinatal Health from 2004 through 2008. Methods: Long-term average (2001–2006) estimates of outdoor PM2.5 were assigned to 50-km–radius circular buffers around each health clinic where births occurred. We used generalized estimating equations to determine associations between clinic-level PM2.5 levels and preterm birth and low birth weight at the individual level, adjusting for seasonality and potential confounders at individual, clinic, and country levels. Country-specific associations were also investigated. Results: Across all countries, adjusting for seasonality, PM2.5 was not associated with preterm birth, but was associated with low birth weight [odds ratio (OR) = 1.22; 95% CI: 1.07, 1.39 for fourth quartile of PM2.5 (> 20.2 μg/m3) compared with the first quartile (< 6.3 μg/m3)]. In China, the country with the largest PM2.5 range, preterm birth and low birth weight both were associated with the highest quartile of PM2.5 only, which suggests a possible threshold effect (OR = 2.54; CI: 1.42, 4.55 and OR = 1.99; CI: 1.06, 3.72 for preterm birth and low birth weight, respectively, for PM2.5 ≥ 36.5 μg/m3 compared with PM2.5 < 12.5 μg/m3). Conclusions: Outdoor PM2.5 concentrations were associated with low birth weight but not preterm birth. In rapidly developing countries, such as China, the highest levels of air pollution may be of concern for both outcomes.

PREVALENCE AND CORRELATES OF SUICIDAL BEHAVIOR AMONG NEW SOLDIERS IN THE U.S. ARMY: RESULTS FROM THE ARMY STUDY TO ASSESS RISK AND RESILIENCE IN SERVICEMEMBERS (ARMY STARRS)

The prevalence of suicide among U.S. Army soldiers has risen dramatically in recent years. Prior studies suggest that most soldiers with suicidal behaviors (i.e., ideation, plans, and attempts) had first onsets prior to enlistment. However, those data are based on retrospective self‐reports of soldiers later in their Army careers. Unbiased examination of this issue requires investigation of suicidality among new soldiers.
