Iatrogenic Arteriovenous Fistula and Retroperitoneal Hemorrhage After Tapping of Lumbar Pedicle Screws
Authors: Makino Takahiro , Kaito Takashi , Sakai Yusuke , Takenaka Shota , Yoshikawa Hideki 
Published: September 2019

Case:
A 76-year-old woman underwent L4–L5 posterior lumbar interbody fusion with pedicle screws for lumbar spondylolisthesis. Intraoperative iatrogenic injuries to the right fourth lumbar artery and inferior vena cava occurred, resulting in arteriovenous fistula with extensive retroperitoneal hemorrhage. Endovascular treatment and intraperitoneal drainage were effective in managing retroperitoneal hemorrhage. She showed no sign of organ failure or deep venous thrombosis during her 2-year follow-up.

Conclusions:
We recommend embolization both proximally and distally in the case of lumbar artery injury. Intra-abdominal hypertension secondary to a massive retroperitoneal hematoma should also be considered to prevent abdominal compartment syndrome.
Chamber Gas Lift in Horizontals
Authors: Hardegree C. N. , Gerrard B. A. , Wildman S. L. , McKenzie K. S. 
Published: September 2019

Summary
In this paper we highlight a pilot project in which chamber gas lift was installed in two unconventional horizontal wells. Chamber gas lift, a combination of deep gas lift and intermittent gas lift, allows for an efficient, closed completion with the cyclic injection of high-pressure gas, which expands and rapidly displaces fluid at high velocity from deep in the well. Development of the system was a collaboration internally and in conjunction with the vendor to install what was historically a vertical-well assembly through the curve section and into a horizontal wellbore. The chamber assembly was successfully designed, sourced, manufactured, installed, and operated. To modify the design from vertical to horizontal applications, components were custom-designed to maintain a sealed chamber. Components deemed most likely to fail are replaceable by slickline intervention. Results indicate a sustained lower downhole pressure than the previous intermittent-gas-lift system, an increase in production, and a good chamber-sweep efficiency.

Published: September 2019

Abstract
A mixed ionic and semiconducting composite in a single-layer configuration has been shown to work as a fuel cell at lower temperature (500-600 o C) than a traditional solid-oxide fuel cell. The performance of such a single-layer fuel cell (SLFC) is often limited by high resistive losses. Here, an eutectic mixture of alkali-carbonates were added to SLFC to improve the ionic transport. The dual-phase composite consisted of ternary carbonate (sodium lithium potassium carbonate) with gadolinium-doped cerium oxide (GDC) as the ionic conductor and lithium nickel zinc oxide as the semiconducting material. The SLFC prepared reached a high power density up to 582 mW/cm 2 (0.22 Scm -1 ) at 600 °C which is more than 30 times better than without the carbonate. The best results were obtained with the ternary carbonate which decreased the the ohmic losses of the cell by more than 95%, whereas a binary carbonate (sodium lithium carbonate) showed a lower conductivity and performance (243 mW/cm 2 , 0.17 Scm -1 at 600°C). Adding carbonates to LNZ-GDC balanced the ratio of electronic and ionic conductivity which positively affected the performance.
Comparison of the effects of empagliflozin and glimepiride on endothelial function in patients with type 2 diabetes: A randomized controlled study
Authors: Tamura Haruka , Kondo Yoshinobu , Ito Kohei , Hasebe Masanori , Satoh Shinobu , Terauchi Yasuo 
Published: September 2019

Abstract
Background : Patients with type 2 diabetes at high risk of cardiovascular events and receiving empagliflozin have a lower rate of primary composite cardiovascular outcomes and death from any cause. Alternatively, treatment with sulfonylurea reduces microvascular complications in diabetes but appears to increase cardiovascular hospitalization or mortality in combination with metformin. In the present study, we therefore assessed the effects of empagliflozin and glimepiride, a sulfonylurea, on endothelial function using flow–mediated dilation (FMD) to estimate arteriosclerosis and cardiovascular events in patients with type 2 diabetes.
Methods : In this prospective, randomized, parallel-group comparison, 58 patients with type 2 diabetes were administered metformin and glargine before bedtime for 12 weeks, followed by the random addition of 10 mg empagliflozin or 0.5 mg glimepiride for 12 weeks. The primary outcome was FMD changes (ΔFMDs), which were measured prior to and following 12 weeks of additional treatment. Secondary outcomes comprised changes in metabolic markers and body composition.
Results : Analysis of the empagliflozin group ( n = 30) and glimepiride group ( n = 28) showed no significant differences in DFMDs (empagliflozin, −0.19 ± 2.34%; glimepiride, −0.37 ± 2.77%; P ＝ 0.79); likewise, HbA1c changes were similar between the groups. Body weight changes significantly differed (empagliflozin, –0.59 ± 2.5 kg; glimepiride, 1.2 ± 3.0 kg; P = 0.02). However, analysis of body composition revealed that body fluid volume significantly decreased only after empagliflozin treatment (baseline, 35.8 ± 6.8 L; after 12 weeks, –0.33 ± 0.72 L; P = 0.03).
Conclusions : Empagliflozin did not improve endothelial function compared with glimepiride in patients with type 2 diabetes, but decreased body fluid volume. This suggested that the coronary protective effect of empagliflozin is not derived by protecting endothelial function but rather from reducing heart failure.
Psychometric properties of the Adelaide Diagnostic Learning Inventory - Brief (ADLIB)
Authors: Minas Harry 
Published: September 2019

Abstract
Objective: There has been increased attention in recent years to mental health, quality of life, stress and academic performance among university students, and the possible influence of learning styles. Brief reliable questionnaires are useful in large-scale multivariate research designs, such as the largely survey-based research on well-being and academic performance of university students. The objective of this study was to examine the psychometric properties of a briefer version of the 39-item Adelaide Diagnostic Learning Inventory.

Results: In two survey samples - medical and physiotherapy students - a 21-item version Adelaide Diagnostic Learning Inventory - Brief (ADLIB) was shown to have the same factor structure as the parent instrument, and the factor structure of the brief instrument was found to generalise across students of medicine and physiotherapy. Sub-scale reliability estimations were in the order of magnitude of the parent instrument. Sub-scale inter-correlations, inter-factor congruence coefficients, and correlations between ADLIB sub-scale scores and several external measures provide support support for the construct and criterion validity of the instrument.

Authors: Kondo Junko , Tomizawa Rie , Jibu Tetsuya , Kamide Kei 
Published: September 2019

Abstract
Objective: The aim of this study was to establish an evaluation index for basic communication skills in basic nursing education. Currently, there are no indicators to evaluate basic communication skills to be acquired in basic nursing education. We attempted to create a communication skills self-efficacy measurement scale based on micro-counseling skills. An anonymous self-administered questionnaire survey was conducted on 238 second-year students from three nursing universities that obtained the consent of the survey cooperation. The questionnaire is a nursing student version counseling self-efficacy / preliminary scale and a characteristic self-efficacy scale created by referring to the explanation of each unit of the micro-counseling skills.
Results: The nursing student communication skill self-efficacy measurement scale included 20 items in 4 factors determined by factor analysis and item sorting. The reliability coefficient of each factor was over .80, and the correlation with the characteristic self-efficacy measurement scale was confirmed at the 1% level.

Abstract
Background: The association between handgrip strength (HGS) and pulmonary function is still controversial, and this relationship has not yet been established among the healthy Chinese Han population.Methods: Data from 1519 healthy Han community dwellers in Beijing were analysed. Subjects were divided into two groups by age: the younger group (<60 years) and the elderly group (≥60 years). Bivariate correlation tests were run between parameters, and variables with a correlation coefficient ǀrǀ≥0.30 and p<0.01 were considered to be significantly correlated. Multiple linear regression analysis was used to adjust covariates in the relationship between HGS and pulmonary function.Results: The study included 623 males and 896 females. The values of HGS were greater in males than in females (40.2 kg vs 25.0 kg, p<0.01) and greater in the younger group than in the elderly group (33.3 kg vs 27.6 kg, p<0.01). HGS and parameters of pulmonary function were highly negatively correlated with age, especially forced expiratory volume in 1 second (r=-0.55, p<0.01), forced expiratory volume in 2 second (r=-0.53, p<0.01) and forced vital capacity (FVC) (r=-0.50, p<0.01). Parameters of pulmonary function were positively associated with HGS, especially the maximum value of vital capacity (VC max) (r=-0.72, p<0.01), forced expiratory volume in 3 second (FEV 3) (r=0.70, p<0.01) and FVC (r=0.69, p<0.01). Therefore, we selected VC max, FEV 3 and FVC as three representative parameters to analyse the relationship between HGS and pulmonary function. In the relationship between HGS and pulmonary function, in addition to gender and age, there were other covariates: height, pulse pressure and systolic blood pressure. After adjusting covariates in the multiple linear regression analysis, the standardized coefficients of HGS on VC max were 0.254 in males and 0.175 in females, and the standardized coefficients of HGS on FVC were 0.225 in males and 0.182 in females.Conclusions: Pulmonary function and HGS were both declined with age. HGS was an independent factor that affected pulmonary function, apart from age. Training in HGS may help to improve pulmonary function in healthy people.
Generation of in vivo labelling tumour cell lines
Authors: Ombrato Luigi , Malanchi Ilaria 
Published: September 2019

Abstract
The characterization of the tumour microenvironment is highly desirable in order to get a better understating on how the tumour cells exploit their neighbours to support their own growth. In Ombrato et al., Nature 2019 we describe a novel strategy that allows 4T1 breast tumour cells to label their lung metastatic niche in vivo. The labelled cells surrounding the tumour cells can be freshly isolated within the all tissue and used for ex vivo assays. Here, we describe how we generated Labelling-4T1 cells. The same procedure can be used to generate labelling cells from other cell lines, but it might require optimization. This protocol is a suggested guide.

Integrating Pathophysiology in Migraine: Role of the Gut Microbiome and Melatonin
Authors: Anderson George 
Published: September 2019

Background:
The pathoetiology and pathophysiology of migraine are widely accepted as unknown.

Methods:
The current article reviews the wide array of data associated with the biological underpinnings of migraine
and provides a framework that integrates previously disparate bodies of data.

Results:
The importance of alterations in stress- and pro-inflammatory cytokine- induced gut dysbiosis, especially
butyrate production, are highlighted. This is linked to a decrease in the availability of melatonin, and a relative
increase in the N-acetylserotonin/melatonin ratio, which has consequences for the heightened glutamatergic excitatory
transmission in migraine. It is proposed that suboptimal mitochondria functioning and metabolic regulation
drive alterations in astrocytes and satellite glial cells that underpin the vasoregulatory and nociceptive changes in
migraine.

Conclusion:
This provides a framework not only for classical migraine associated factors, such as calcitonin-gene
related peptide and serotonin, but also for wider factors in the developmental pathoetiology of migraine. A number
of future research and treatment implications arise, including the clinical utilization of sodium butyrate and
melatonin in the management of migraine.
Prioritizing Key Duration Estimation Accuracy Factors in Highway Infrastructure Projects Using Fuzzy AHP
Authors: Meharie Meseret Getnet , Gariy Zachary C. Abiero , Mutuku Raphael Ngumbau Ndisya , Mengesha Wubshet Jekale 
Published: September 2019

Background:At the early phase of project development, highway engineering estimators seek to determine the duration of highway construction projects for the purpose of construction planning and administration. Thus, it is vital to study and analyze the estimation accuracy factors of highway construction project duration. In this regard, several studies have been conducted to identify and analyze the estimation accuracy factors of project duration in various ways to improve the estimation and management performance of all the contracting parties. However, very less effort has been devoted to evaluating the duration estimation accuracy factors in the case of the highway construction industry under fuzzy environment.Objective:This paper aims to analyze and prioritize the critical factors that potentially affect the duration estimation accuracy of the highway construction projects in Ethiopia under fuzzy environment.Methods:An extensive review and discussions with highway engineering experts were carried out to explore and identify the duration estimation accuracy factors. The study data collection process consists of two stages. The first stage is to conduct a questionnaire survey. Whereas, the second stage is to carry out the pair-wise comparison matrix to capture the imprecision and vagueness in subjective responses. Then, a λ-cut set method to reduce the initial list of factors and exploratory factor analysis was used to classify the reduced set of factors into smaller groups. Finally, a fuzzy hierarchy process algorithm with the use of triangular fuzzy numbers was presented for prioritizing critical factors.Results:A cut -off value, λ = 0.95, was verified which resulted in the identification of critical accuracy factors. Accordingly, 12 critical factors were opted and categorized as a cluster of similar items into 5 groups. Finally, the analytical results obtained from fuzzy AHP algorithm revealed that project complexity, project size, bridge type and complexity were found to be the four top-ranked factors based on the global priority weight.Conclusion:These factors must be a serious concern in estimating and administering the contract and the duration of highway construction projects at the early phases of project development so that the time deviation upon the completion of the project can be minimized.
Low Self-Esteem and Selfie Posting Among Young Women
Authors: Biolcati Roberta 
Published: September 2019

Background:
Self-esteem is a critical factor in online impression management strategies and could play a crucial role in explaining women’s selfie-posting behaviours. Previous works examining relationships between self-esteem and self-presentation on social media have yielded controversial results.

Objective:
This study was performed to clarify the relationship between self-esteem and the frequency of taking and posting own, group and partner selfies on Social Networking Sites (SNS).

Methods:
A sample of 692 Italian young women (18-28 years old) completed questionnaires on self-esteem, satisfaction with life, body satisfaction and selfie posting bahaviours. The low self-esteem group was compared with the high self-esteem group.

Results:
Results showed that women with low self-esteem are more dissatisfied with their body image and life and significantly they post fewer types of selfies compared to women with high self-esteem.

Conclusion:
Findings from this study provide new insights into the relation between self-esteem and selfie impression management strategies.
Development of Filipino Nurse Educator’s Wellbeing Survey (FNEWS): An Exploratory Sequential Mixed Methods Study
Authors: Salvador Jordan T. , Alqahtani Friyal M. , Al-Garni Rima S. Sareh 
Published: September 2019

Background:
The role of a nurse educator is a vital component in the management process of teaching and learning development of students. Ensuring excellent wellbeing for nurse educators may lead to increased job satisfaction and work performance.

Objective:
The objective of this study was to develop a survey tool that measures the wellbeing of Filipino nurse educators working in four Gulf Cooperation Council (GCC) countries.

Methods:
Three-phase sequential approach was obtained. The investigation started with a qualitative investigation of 20 Filipino nurse educators based from Saudi Arabia, United Arab Emirates, Oman, and Bahrain followed by a development of survey tool measuring the Filipino nurse educator’s wellbeing. The survey tool was distributed among 112 participants in Saudi Arabia. Data were analyzed and interpreted by means of a Colaizzi method for qualitative and descriptive statistics using SPSS for quantitative measures.

Results:
All the themes emerged from the qualitative phase were discussed from the gathered review of literature and studies. Themes, contextual categories, and significant statements were used as survey constructs measuring the wellbeing of the participants. Moreover, a valid and reliable survey tool called ‘Filipino Nurse Educator’s Wellbeing Survey’ (FNEWS) was developed and surveyed among the Filipino nurse educators in Saudi Arabia, revealing an ‘acceptable’ level of wellbeing.

Conclusion:
Knowing the level of wellbeing of nurse educators will be an effective way to provide the competency needed to address burnout, low job satisfaction, and compassion fatigue, thereby increasing the likelihood of safeguarding the welfare of the nurse educators.
Age-Related Argonaute Loading of Ribosomal RNA Fragments
Authors: Guan Lingyu , Grigoriev Andrey 
Published: September 2019

Background:
Accumulating evidence points to the functional roles of rRNA derived
Fragments (rRFs), often considered degradation byproducts. Small RNAs, including miRNAs and
tRNA-derived Fragments (tRFs), have been implicated in the aging process and we considered rRFs
in this context.

Objective:
We performed a computational analysis of Argonaute-loaded rRFs in Drosophila melanogaster
to study rRF changes with age. We determined rRF abundance in Ago1 and Ago2 at 3 and 30
days to identify Ago1-guided and Ago2-guided fragments. We searched for putative seed sequences
in rRFs based on frequent matches of sliding k-mer windows to the conserved regions of 12 Drosophila
genomes. We predicted putative targets (containing matches to seeds identified in four rRFs)
and studied their functional enrichments using Gene Ontology.

Results:
We identified precise cleavage sites of distinct rRF isoforms from both nuclear and mitochondrial
rRNAs. The most prominent rRF isoforms were enriched in Ago2 at 3 days and that loading
strongly decreased with age. For less abundant rRFs, loading of Ago2-guided rRFs generally increased
in Ago2, whereas Ago1-guided rRFs revealed diverse patterns. The distribution of seed
matches in targets suggested that rRFs may bind to various conserved regions of many genes, possibly
via miRNA-like seed-based mechanisms.

Conclusions:
Our observations suggest that rRFs may be functional molecules, with age-dependent
Argonaute loading, comparable to that of miRNAs and tRFs. The putative rRF targets showed significant
enrichment in developmental processes and biological regulation, similar to tRFs and consistent
with a possible involvement of these newly identified small RNAs in the Drosophila aging.
Modeling and Simulation for Multiple Damage Progression of Tank-to- Engine Fuel Feed System
Authors: Wenjuan Li , Haiqiang Liu , Bo Zhang 
Published: September 2019

Background:
A centrifugal vane pump driven by a three-phase AC motor is a key component
for modern equipment. Therefore, its condition directly affects the operating and safety performance
of the system. Modeling and simulation are effective methods for the system analysis.

Methods:
A mathematical model of a Tank-to-Engine Fuel Feed System (T-EFFS) is designed
based on its phased-mission behavior and structure redundancy. Both of the damage modes that
arise frequently in a given type of system are tracked: the fuel feed pump seal damage due to fatigue
and the vane damage due to corrosion. Then, a multiple degradation T-EFFS model is established to
simulate the fuel pressure at the system outlet under different damage modes. The morphological
spectrum decrement index is used to describe the damage of the system.

Results:
The results show that the T-EFFS model can describe the phased-mission behavior of the
system and meet the requirement of the fuel flow rate for the entire mission profile. Then, the decrease
in the fuel pressure of the T-EFFS with the cumulative effects of vane damage and crack
growth under different behavior modes is simulated along its life span.

Conclusion:
This work aims to provide a model and data support for a subsequent investigation.
The results can be used to fit the health background curve of the system, predict the performance degradation
trend of the system at given life points, and further evaluate its remaining service life.
