Authors: Xie Manman , Huan Guolan , Xia Weiwei , Feng Xia , Chen Li , Zhao Yiping 
Published: April 2017

Abstract
The poly(vinylidene fluoride) (PVDF)/chitin (CH) blend membranes were prepared by the immersion phase inversion method using N,N-dimethylacetamide (DMAc)/lithium chloride (LiCl) as the co-solvent. It was found that blending CH with PVDF allowed membranes to have a better hydrophilicity, penetrability, antifouling and antibacterial performance. In order to improve the performance of PVDF/CH blend membranes further, water/ethanoic acid (HAc) solutions with different compositions were employed as coagulation baths. The effects of HAc volume percentage in coagulation baths on the surface composition, morphology, wettability, water flux, antifouling and antibacterial property of PVDF/CH membrane were investigated. The results indicated that the content of CH on the surface of the membrane increased with the increase of HAc concentration in coagulation baths, which contributed to an improvement of hydrophilicity. The increasing HAc content in coagulation baths also led to a change from finger-like pores to sponge-like pores and a decrease of porosity for PVDF/CH blend membranes. When increasing HAc concentration, the antifouling performance of the blend membranes was improved. Meanwhile, the amidogen of CH on PVDF/CH membrane surfaces could suppress the growth of bacteria, and the blend membrane showed an improved antibacterial performance with the volume ratio of HAc increasing.
Modelling drug transport during intraperitoneal chemotherapy
Authors: Steuperaert Margo , Debbaut Charlotte , Segers Patrick , Ceelen Wim 
Published: April 2017

AbstractDespite a strong rationale for intraperitoneal (IP) chemotherapy, the actual use of the procedure is limited by the poor penetration depth of the drug into the tissue. Drug penetration into solid tumours is a complex mass transport process that involves multiple parameters not only related to the used cytotoxic agent but also to the tumour tissue properties and even the therapeutic setup. Mathematical modelling can provide unique insights into the different transport barriers that occur during IP chemotherapy as well as offer the possibility to test different protocols or drugs without the need for in vivo experiments. In this work, a distinction is made between three different types of model: the lumped parameter model, the distributed model and the cell-based model. For each model, we discuss which steps of the transport process are included and where assumptions are made. Finally, we focus on the advantages and main limitations of each category and discuss some future perspectives for the modelling of IP chemotherapy.

Abstract
There are many factors that strongly influence the aetiology, development, and progression of cognitive decline in old age, mild cognitive impairment (MCI), and Alzheimer’s disease (AD). These factors include not only different personality traits and moods but also lifestyle patterns (e.g. exercise and diet) and awareness levels that lead to cognitive decline in old age. In this review, we discuss how personality traits, mood states, and lifestyle impact brain and behaviour in older adults. Specifically, our review shows that these lifestyle and personality factors affect several brain regions, including the hippocampus, a region key for memory that is affected by cognitive decline in old age as well as AD. Accordingly, appropriate recommendations are presented in this review to assist individuals in decreasing chances of MCI, dementia, AD, and associated symptoms.
Co-Investments and Tacit Collusion in Regulated Network Industries: Experimental Evidence
Authors: Krämer Jan , Vogelsang Ingo 
Published: April 2017

AbstractSeveral regulatory authorities have recently allowed competing network operators to co-invest in network infrastructure. With the use of a laboratory experiment, we investigate the impact of co-investments on competition in regulated network industries, particularly in comparison to unilateral and duplicate investments. Our main finding is that co-investment (i.e. cooperation at the infrastructure level) facilitates tacit collusion (i.e. cooperation at the retail level) significantly, which questions the positive evaluation of co-investments with respect to consumers’ surplus in the theoretical literature.

Published: April 2017

The study investigated the academic engagement and achievement orientation as correlates of reading culture of in-school adolescents in Enugu State, Nigeria. Using correlational survey research design, the study made use of a population of 3469 senior secondary 11 (SS11) in-school adolescents. A purposive sampling and stratified random sampling techniques were used to draw a sample of 340 in-school adolescents. Four research questions and two null hypotheses tested at 0.05 level of significance guided the study. The three instruments used for data collection were in-school adolescents’ academic engagement scale (IAES), in-school adolescents’ achievement orientation scale (IAAOS) and in-school adolescents’ reading culture scale (IARCS). Research questions 1-3 were answered using means and standard deviation whereas research questions 4 and 5 were answered using Pearson r and R-square. The hypotheses were tested using analysis of variance (ANOVA) at 0.05 level of significance. It was found that in-school adolescents’ academic engagement and achievement orientation significantly related with their reading culture. Based on the findings of the study, it was recommended among others that, the government, school administrators and educators put concerted effort to encourage students to be mastery oriented and academically engaged in order to prevent deleterious outcomes associated with poor reading culture since high academic engagement and high achievement orientation relates with positive academic outcomes. Keywords: Adolescence, Academic Engagement, Cognitive Engagement, Achievement Orientation and Reading Culture.

Published: April 2017

The aim of the study is to investigate the influence of physiological and psychosocial stress on the quality of life (QoL) in a group of hemodialysis (HD) patients from our center. Materials and methods: A number of 70 patients were included in the study. We used the Hemodialysis Stressors Scale, in order to estimate the stress level, and the Short Form-36 (SF-36) Health Survey Questionnaire, to evaluate the QoL. Results: The M for age = 54.5 ± 11.7 years and 38.6% were men. Patients with a low level of stress had significantly higher physical health (M = 53,52; p = 0.04) and mental health (M = 51,61; p <0.01) scores. The disease-related factors that induced the highest level of stress were the physical symptoms (1.67 ± 0.68), the food and water intake restrictions (1.64 ± 0.76), the vascular access problems (1.44 ± 0.83), the daily activity limitations (1.22 ± 0.72), the dependence on the medical staff (1.14 ± 0.74). Socio-economical and demographical factors had no effect on stress and QoL. Conclusions: The study prove the importance of stress for the QoL in HD patients. Efforts should be undertaken to minimize stress factors. Keywords: Dialysis; stress; physical well-being; psychological well-being; quality of life;
Psychometric Properties of Job Satisfaction Scale in Slovak Helping Professions: Preliminary Results
Authors: Mesarosova Margita 
Published: April 2017

Problem Statement; Job satisfaction is associated with positive outcomes at work and in certain other aspects of life. Job satisfaction is regarded as an important indicator to determine the levels of career success and accomplishment. In the past decades, job satisfaction among the worker in helping professions has received little attention in Slovakia. Purpose of Study; The purpose of this study was to adapt JSS to Slovak language so that it can be used in Slovakia especially on helping personnel in social care. In this study, we aimed to confirm its factor structure, analyse its convergent and discriminant validity, and internal consistency. Methods; The 36-item Job Satisfaction Scale (JSS, Spector, 1985) was used to measure job satisfaction. This scale was translated into Slovak language using forward translation, assessment of forward translation, backward translation, assessment of backward translation, and local meeting with professionals. External students of social work and workers who practiced helping professions in social care participated in the research and completed Job Satisfaction Scale, Professional Quality of Life Scale (Stamm (2010), Life Orientation Test – Revised (Scheier, Carver, & Bridges (1994), Scales on Well-Being (SEHP) (Dzuka, & Dalbert, 2002). The internal consistency and discriminant validity of JSS was examined. Findings and Results; It was revealed that higher level of job satisfaction was linked with optimism, higher frequency of experiencing positive emotions and lower frequency of experiencing negative emotions. Conclusions; The preliminary results confirmed the factor structure of JSS. Description of the psychometric properties of the Slovak version of the Job Satisfaction Scale and the interpretation of the results will be discussed in the paper.

An Examination of the Relationship between Flow Parameters and Symptoms According to Fire Phase in a Mine Model
Authors: Kecel Selcuk 
Published: April 2017

This study examines the relationship between temperature, CO dispersions, symptoms, and COHb% levels accumulated in the blood on available ventilation conditions in cases of fire at point in an underground mine model. Based on operating parameters (air velocity and direction) of the ventilation system in the underground mine model, fast growing phase fire analyses were conducted according to the heat release rate (HRR) value in the range of 0-61.34MW. In fire scenarios prepared according to the hydrocarbon fuel type (C2.3H4.2O1.3), boundary conditions were calculated depending on the combustion equation considering fuel lower heating value (Qc). CO dispersions inside the tunnel were examined by transferring the time-dependent boundary conditions to the computational fluid dynamics (CFD) program. yCO, COHb%, and COHb%/âˆ†t changes were calculated according to the HRR value. Findings regarding the effects of CO emission (acute and chronic poisoning), were expressed according to the HRR value.

Depression and Patient-Reported Outcomes Following Total Shoulder Arthroplasty
Authors: Werner Brian C. , Wong Alexandra C. , Chang Brenda , Craig Edward V. , Dines David M. , Warren Russell F. , Gulotta Lawrence V. 
Published: April 2017

Background:
Recent studies have found that depression is associated with increased pain and impairment following lower-extremity arthroplasty; however, this association has not been investigated for total shoulder arthroplasty. The objective of this study was to investigate the association between depression and patient-reported outcomes following total shoulder arthroplasty.

Methods:
A prospectively collected institutional registry was queried for consecutive patients who underwent total shoulder arthroplasty for osteoarthritis from 2007 to 2013 with baseline and minimum 2-year postoperative American Shoulder and Elbow Surgeons (ASES) scores. Revision procedures and total shoulder arthroplasty for diagnoses other than osteoarthritis were excluded. Patients with a preoperative diagnosis of depression (n = 88) formed the study cohort; control patients without a diagnosis of depression were matched to the study patients by age and sex in a 2:1 ratio (n = 176). Baseline characteristics and patient-reported outcome measures were compared between groups, as were minimum 2-year patient-reported outcomes and change in patient-reported outcomes. A multivariable regression was performed to investigate the independent effect of depression on improvement in ASES scores.

Results:
Except for the Short Form-12 Mental Component Summary (SF-12 MCS) scores, there were no significant differences (p > 0.05) in baseline characteristics between study patients and controls. There was a significant improvement in the ASES score for patients with depression (p < 0.0001) and controls (p < 0.0001). Patients with depression had significantly lower final ASES scores (p = 0.001) and less improvement in ASES scores (p = 0.001) and SF-12 Physical Component Summary scores (p = 0.006) as well as lower satisfaction levels at 2 years; however, the latter difference did not reach clinical importance. Depression (p = 0.018) was an independent predictor of less improvement in ASES scores.

Conclusions:
Patients with a diagnosis of depression should be counseled that they will experience a significant clinical improvement from baseline after total shoulder arthroplasty. A preoperative diagnosis of depression is an independent predictor of significantly less improvement in ASES scores following total shoulder arthroplasty; however, this difference does not reach clinical importance and should not discourage patients with a clinical diagnosis of depression from undergoing total shoulder arthroplasty.

Level of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
OBJECTIVE To evaluate the agreement between results of microscopic examination and bacterial culture of bile samples from dogs and cats with hepatobiliary disease for detection of bactibilia.
DESIGN Cross-sectional study.
ANIMALS 31 dogs and 21 cats with hepatobiliary disease for which subsequent microscopic examination and bacterial culture of bile samples was performed from 2004 through 2014.
PROCEDURES Electronic medical records of included dogs and cats were reviewed to extract data regarding diagnosis, antimicrobials administered, and results of microscopic examination and bacterial culture of bile samples. Agreement between these 2 diagnostic tests was assessed by calculation of the Cohen κ value.
RESULTS 17 (33%) dogs and cats had bactibilia identified by microscopic examination of bile samples, and 11 (21%) had bactibilia identified via bacterial culture. Agreement between these 2 tests was substantial (percentage agreement [positive and negative results], 85%; κ = 0.62; 95% confidence interval, 0.38 to 0.89) and improved to almost perfect when calculated for only animals that received no antimicrobials within 24 hours prior to sample collection (percentage agreement, 94%; κ = 0.84; 95% confidence interval, 0.61 to 1.00).
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that agreement between microscopic examination and bacterial culture of bile samples for detection of bactibilia is optimized when dogs and cats are not receiving antimicrobials at the time of sample collection. Concurrent bacterial culture and microscopic examination of bile samples are recommended for all cats and dogs evaluated for hepatobiliary disease.
