Published: November 2017

Atualmente, a alteração do uso original de prédios históricos por espaços expositivos é uma alternativa de preservação destas construções. Entretanto, é comum o surgimento de danos após o processo de retrofit, em razão das alterações microclimáticas ideais para o novo uso. A fim de conhecer as potencialidades do prédio em razão dos sistemas construtivos, o objetivo principal desta pesquisa é analisar a influência da existência de porões ventilados, em prédios históricos com novos usos, na incidência de manifestações patológicas. Para isso, foram analisadas três edificações do século XIX, das quais duas possuem porão ventilado. Para a análise foram escolhidos ambientes com mesma orientação solar e com o novo uso de sala de exposições. O estudo contou com levantamentos visuais e fotográficos trimestrais, durante 12 meses, a fim de avaliar o comportamento dessas manifestações. Além disso, imagens termográficas das paredes internas foram realizadas, para visualizar o comportamento da umidade ascendente nesses espaços. Concluiu-se que, para prédios sem porão ventilado, não são indicados novos usos que impossibilitem as trocas de ar periódicas e a incidência de luz solar em seu interior, visto que tendem a causar danos aos materiais construtivos.

Abstract

Currently, the alteration of the original use of historic buildings by exhibition rooms is an alternative of preservation of these constructions. However, it is common that the building develop damages after the retrofit process, due to the ideal microclimatic changes for the new use. In order to know the potentialities of the buildings that related to the constructive systems, the main objective of this paper is to analyze the influence of the existence of ventilated basements, in historical buildings with new uses, in the incidence of pathological manifestations. For this, three buildings of the nineteenth century were analyzed, two of this have ventilated basement. For the analysis were chosen environments with the same solar orientation and with the new use of the exhibition room. For the study had quarterly visual and photographic surveys for 12 months in order to evaluate the behavior of the pathological manifestations. In addition, thermographic images of the inner walls were performed, to visualize the behavior of ascent humidity in these spaces. It was concluded that, for buildings without a ventilated basement, no new uses are indicated that would prevent periodic air changes and the incidence of sunlight in their interior, since they tend to cause damage to the building materials.

RESUMO: A busca por novos materiais capazes de substituir, em parte, componentes do concreto tem alavancado pesquisas em diversas áreas, principalmente no que se refere à reciclagem de resíduos (construção, indústria e outros). Neste contexto, a utilização de isoladores elétricos de porcelana vem sendo estudada como uma possibilidade eficaz de substituição do agregado miúdo. Este trabalho, avaliou os efeitos da substituição de 25% e 50%, em relação ao agregado miúdo, utilizando um traço de 1:1,43:2,07:0,4 (cimento:agregado graúdo:agregado miúdo:água) e, através da caracterização física do resíduo, o mesmo foi classificado como areia grossa (influência do processo de moagem). Realizou-se ensaios de absorção (aos 28 dias), resistência à compressão e à tração. O ensaio de absorção comprovou que o isolador, mesmo tendo maior absorção do que a areia natural (0,56% e 0,34%, respectivamente) não interferiu no valor do abatimento do concreto. Os resultados de resistência à compressão mostraram uma melhora considerável com base nos dados obtidos, comprovando a eficácia da utilização deste material como substituição parcial dos agregados na composição do concreto.ABSTRACT: The search for new materials capable of partially replacing concrete components has leveraged research in a number of areas, particularly with regard to waste recycling (construction, industry and others). In this context, the use of porcelain electrical insulators has been studied as an effective possibility of replacing the small aggregate. In this paper evaluated the effects of 25% and 50% substitution in relation to the fine aggregate using a 1: 1: 43: 2.07: 0.4 (cement: aggregate coarse: fine aggregate: water). Through the physical characterization of the residue, the same was classified as coarse sand (influence of the grinding process). Absorption (at 28 days), compressive strength and tensile were performed. The absorption test showed that the insulator, although having a higher absorption than the natural sand (0.56% and 0.34%, respectively), did not interfere with the value of the slump test of concrete. The results of compressive strength showed a considerable improvement based on the data obtained, proving the effectiveness of the use of this material as partial replacement of the aggregates in the concrete composition.

Published: November 2017

Grey blight is a foliar disease of tea plants (Camellia sinensis) caused by Pestalotiopsis. The grey blight pathogen was isolated from infected leaves of tea plants in the National Tea and High Value Crop Research Institute (NTHRI), Shinkiari, Khyber Pakhtunkhwa, Pakistan. Eight different varieties, Indonesian, Roupi, Jue King, P-5, P-3, Qi man, Chuy and P-1, were investigated for yield loss and resistance against the grey blight disease. All varieties displayed considerably different levels of resistance to Pestalotiopsis (p<0.05). The most resistant variety was Indonesian, which showed the lowest number of lesions (1.5 leaf-1) and the smallest lesion diameter (3.0 cm), whereas the most susceptible variety was P-1 which showed the highest number of lesions (3.83 leaf-1) and the largest lesion diameter (15.0 cm). The grey leaf blight pathogen significantly affected biomass and dry matter of the tested varieties. Compared to non-inoculated control, inoculation with Pestalotiopsis reduced the number of leaves by 40% (p<0.05), fresh leaf weight by 31% (p<0.05) and dry leaf weight by 59% (p<0.05). Whereas, the Indonesian variety was the least affected showing only 11% (p<0.05), 19% (p<0.05), and 28% (p<0.05) reduction in number of leaves, fresh weight and dry weight, respectively, over control. These results showed that Pestalotiopsis significantly reduced tea yield and that this disease can be managed by growing resistant varieties.

Published: November 2017

Purpose:

To assess the correlation between the disc damage likelihood scale (DDLS) objectively measured by a nonmydriatic fundus camera, confocal laser scanning ophthalmoscopy (HRT3), and spectral-domain optical coherence tomography (SD-OCT) in uveitic glaucoma.

Methods:

A total of 59 patients with uveitic glaucoma (21 female, 38 male; mean age 56.8 ± 18.7 years) were included in this prospective cross-sectional study. All patients were measured by the Kowa Nonmyd WX 3D camera (2D/3D nonmydriatic retinal camera, Kowa Company), the HRT3 (Heidelberg Engineering), and SD-OCT (Carl Zeiss Meditec) by one examiner on the same day. All 3 devices graded the optic disc topography. Statistical data were calculated using SPSS (v 20.0, SPSS).

Results:

In patients showing borderline results in one of the modalities (n = 45), the DDLS showed a significant correlation with the retinal nerve fiber layer (p = 0.016), while Moorfields regression analysis (p = 0.550) and glaucoma probability score (p = 0.629) did not correlate significantly. The highest predictive power was demonstrated by the objectively measured DDLS (area under the receiver operating characteristic curve 0.445-0.588), compared to R. Burk (0.149-0.375) and F.S. Mikelberg (0.033-0.450) coefficients considering HRT and optical coherence tomography.

Conclusions:

In this study cohort, the objective DDLS showed the highest predictive power and thus is a reliable tool in diagnosing uveitic glaucoma. These 3 devices cannot be used interchangeably. As diagnosis and follow-ups are challenging in uveitis patients, the stereophotography is additionally a valuable tool.

Published: November 2017

Introduction

Patients with hip fractures are usually treated operatively in Western Europe. However, in Mid-Asia different indications are used to decide whether this patient is suitable for operative treatment and those are related to specific traditions and rules in hospital. Thus, traditions and surgeon/patient fears seem to affect treatment choices in hip fractures and subsequent outcomes. The aim of our study was to investigate patients with hip fractures and compare outcome at 1-year follow-up in the operated and nonoperated patient groups.

Methods

All patients over 50 years old who sustained a hip fracture, between January 2014 and December 2014, were included. Patients were assessed preoperatively and at 1-year follow-up, using questionnaires from National Swedish Hip Fracture Register and quality of life (Euroqol EQ-5D).

Results

Out of 398 included patients, 299 were operated on and 99 were not. 344 patients remained for our analysis before the end of 1-year follow-up. 51 patients (65%) deceased in the nonoperated group as compared to 55 (21%) in the operated group, p<0.001. Out of 27 patients in the nonoperated group hip function was evaluated at 1-year follow-up, 11 (41%) were walking independently or using 1 stick, as compared to 192 (91%) in the operated group.

Conclusions

We conclude that nonoperative treatment of hip fracture patients is associated with higher mortality and worse functional outcome as compared to those who were treated operatively. We therefore advocate operative treatment of the hip fracture in the vast majority of cases.

Introduction:

Given that it is difficult to randomize end-stage renal disease (ESRD) patients to either hemodialysis (HD) or peritoneal dialysis (PD), differences between these renal replacement therapy (RRT) modalities are of major interest and remain controversial.

Methods:

All data on maintenance dialysis patients during 2009 to 2013 in the Renji Hospital in Shanghai, China and in the San Bortolo Hospital in Vicenza, Italy were selected. Patients who changed their therapy from HD to PD or PD to HD during this study were excluded.

Results:

919 maintenance dialysis patients were included in the present study, including 509 patients on HD and 410 on PD. During the 5-year follow-up, mean arterial pressure (MAP) was higher in HD patients. The level of serum HCO3- was significantly better in PD patients than in HD patients. Phosphate was significantly higher in HD patients than in PD patients. With respect to lipid metabolism, triglyceride, total cholesterol and LDL were significantly higher in PD patients. Serum protein and albumin were higher in HD patients than in PD patients. Overall, 236 patients died (25.7%); 150 (16.3%) on HD and 86 (9.4%) on PD. The main cause of death in HD and PD patients was cerebral vascular disease and infection, respectively. After adjusting for dialysis vintage, the Kaplan-Meier patient survival was similar between HD and PD patients.

Conclusions:

Based on 5 years of data, we demonstrate that lipid metabolism and nutritional status were better in HD patients. However, blood pressure control, acid-base balance, phosphate (P) control were better in PD patients. The main cause of death in HD and PD was cerebral vascular disease and infection, respectively. Considering the dialysis vintage, the Kaplan-Meier patient survival was similar between HD and PD patients.

Published: November 2017

Purpose:

The current 1-dimensional fluid structure interaction model (FSI) for understanding cerebrospinal fluid (CSF) circulation requires pulsatility as a precondition and has not been applied to patients with continuous-flow left ventricular assist devices (CF-LVAD) where pulsatility is chronically reduced. Our study aims to characterize the behavior of CSF pressure and flow in patients with CF-LVADs using a computational FSI model.

Methods:

Utilizing the computational FSI model, CSF production in choroid plexuses of the 4 ventricles was specified as a boundary condition for the model. The other source of production from capillary ultrafiltrate spaces was accounted for by the mass conservation equation. The primary CSF absorption sites (i.e., arachnoid granulations) were treated as the outlet boundary conditions. We established a low pulse wave to represent patients with a CF-LVAD.

Results:

From the model, low pulse conditions resulted in a reduction in CSF pressure amplitude and velocity though the overall flow rate was unchanged.

Conclusions:

The existing FSI model is not a suitable representation of CSF flow in CF-LVAD patients. More studies are needed to elucidate the role of pulsatility in CSF flow and the compensatory changes in CSF production and absorption that occur in patients with CF-LVADs in whom pulsatility is diminished.

Published: November 2017

Background and purpose

Acute Kidney Injury (AKI) is a severe complication affecting many hospitalized patients after cardiac surgery, with negative impacts on short- and long-term clinical outcomes and on healthcare costs. Recently, clinical interest has been aimed at defining and classifying AKI, identifying risk factors and developing diagnostic strategies to identify patients at risk early on. Achieving an early and accurate diagnosis of AKI is a crucial issue, because prevention and timely detection may help to prevent negative clinical outcomes and avoid AKI-associated costs. In this retrospective study, we evaluate the NephroCheck Test as a diagnostic tool for early detection of AKI in a high-risk population of patients undergoing cardiac surgery at the San Bortolo Hospital of Vicenza.

Methods

We assessed the ability of the NephroCheck Test to predict the probability of developing CSA-AKI (cardiac surgery-associated AKI) and evaluated its accuracy as a diagnostic test, by building a multivariate logistic regression model for CSA-AKI prediction.

Results

Based on our findings, when the results of the NephroCheck Test are included in a multivariate model its performance is substantially improved, as compared to the benchmark model, which only accounts for the other clinical factors. We also define a rule – in terms of a probability cut-off – for discriminating cases that are at higher risk of developing AKI of any stage versus those in which AKI is less likely.

Conclusions

Our study has implications in clinical practice: when a Nephrocheck Test result is >0.3 ng/dL, an automated electronic alert prompts the physician to intervene by following a checklist of preventive measures.
Unfavorable clinical implications of peripheral blood CD44+ and CD54+ lymphocytes in patients with lung cancer undergoing chemotherapy
Authors: Luo Zhuanbo , Wang Yun , Lou Yanru , Cao Chao , Hubbard Richard , Xu Ning , Huang Xiaoping
Published: November 2017

Background:

There is an unmet need for identification of additional prognostic markers for lung cancer. The aim of this study was to identify novel clinical and immunological predictors of prognosis in lung cancer patients.

Methods:

Lymphocyte subsets CD3+, CD4+, CD8+, CD4+/8+, CD25+, CD69+, CD44+ and CD54+ were quantified in peripheral blood using flow cytometry, for 203 newly diagnosed lung cancer patients and 120 healthy controls.

Results:

The levels of CD3+, CD4+, CD8+, CD4+/CD8+ and CD69+ lymphocytes were significantly lower in patients with lung cancer compared with the healthy control group, while CD54+ and CD44+ lymphocytes were significantly higher. In stage III/IV patients with lymph node metastasis or distant metastasis, the levels of CD44+ and CD54+ lymphocytes were significantly increased compared with patients with stage I/II disease (p<0.05). The levels of CD44+ and CD54+ lymphocytes markedly reduced after chemotherapy, and follow-up analysis indicated that patients found without increase of CD44+ and CD54+ lymphocytes after chemotherapy had survival advantages. Independent predictors of survival in lung cancer patients included clinical stage (hazard ratio [HR] = 2.791; 95% confidence interval [95% CI], 1.42-3.54, p<0.001), CD44+ lymphocytes (HR = 1.282; 95% CI, 1.02-1.49, p = 0.002) and CD54+ lymphocytes (HR = 1.475; 95% CI, 1.22-1.73, p = 0.003). Elevated levels of CD44+ and CD54+ lymphocytes correlated with poor prognosis in lung cancer patients.

Conclusions:

Peripheral blood lymphocyte subsets in patients with lung cancer are different from those in healthy people, and circulating CD44+ and CD54+ lymphocytes seem to be a promising criterion to predict survival in lung cancer patients undergoing chemotherapy.

Published: November 2017

Background:

Bladder cancer (BC) represents the most common neoplasm of the urinary tract. Although cystoscopy and urine cytology represent the gold standard methods to monitor BC, both procedures have limitations. Therefore, the identification of reliable biomarkers for early and noninvasive detection of BC is urgently required.

Methods:

In this study, we analyzed nicotinamide N-methyltransferase (NNMT) expression in urine samples from 55 BC patients and 107 controls, using real-time polymerase chain reaction (PCR). Receiver operating characteristic (ROC) analysis was used to identify the best cutoff value to discriminate BC patients from healthy donors, and to evaluate the diagnostic accuracy of a urine-based NNMT test.

Results:

The results demonstrated that urinary NNMT expression was significantly (p<0.05) higher in BC patients. Moreover, a significant (p<0.05) inverse correlation was found between NNMT expression and histological grade. The ROC analysis revealed that a ΔCq of 13.3 was the best cutoff value, since it was associated with the highest combination of sensitivity and specificity. Moreover, the area under the curve (AUC) value was 0.913 (p<0.05), indicating the excellent diagnostic accuracy of a urine-based NNMT test.

Conclusions:

Our data indicate that NNMT is a promising biomarker that could be used to support the early and noninvasive diagnosis of BC.
Monitoring the osseointegration process in porous Ti6Al4V implants produced by additive manufacturing: an experimental study in sheep
Authors: Kayacan Mehmet C. , Baykal Yakup B. , Karaaslan Tamer , Özsoy Koray , Alaca İlker , Duman Burhan , Delikanlı Yunus E.
Published: November 2017

Background:

This study investigated the design and osseointegration process of transitive porous implants that can be used in humans and all trabecular and compact bone structure animals. The aim was to find a way of forming a strong and durable tissue bond on the bone–implant interface.

Methods:

Massive and transitive porous implants were produced on a direct metal laser sintering machine, surgically implanted into the skulls of sheep and kept in place for 12 weeks. At the end of the 12-week period, the Massive and porous implants removed from the sheep were investigated by scanning electron microscopy (SEM) to monitor the osseointegration process.

Results:

In the literature, each study has selected standard sizes for pore diameter in the structures they use. However, none of these involved transitional porous structures. In this study, as opposed to standard pores, there were spherical or elliptical pores at the micro level, development channels and an inner region. Bone cells developed in the inner region. Transitive pores grown gradually in accordance with the natural structure of the bone were modeled in the inner region for cells to develop. Due to this structure, a strong and durable tissue bond could be formed at the bone–implant interface.

Conclusions:

Osseointegration processes of Massive vs. porous implants were compared. It was observed that cells were concentrated on the surface of Massive implants. Therefore, osseointegration between implant and bone was less than that of porous implants. In transitive porous implants, as opposed to Massive implants, an outer region was formed in the bone–implant interface that allowed tissue development.
Experimental study on the chemico-physical interaction between a two-component cyanoacrylate glue and the material of PICCs
Authors: Di Puccio Francesca , Giacomarro Daniela , Mattei Lorenza , Pittiruti Mauro , Scoppettuolo Giancarlo
Published: November 2017

Introduction:

The use of cyanoacrylate glue as sealant on the exit site of peripherally inserted central catheters (PICCs) may offer some important clinical advantages. However, concerns exist about the potential interaction between cyanoacrylate and the material of the catheter itself. The aim of this study was to investigate the possibility of damage to the catheter secondary to a long-term contact with a two-component skin glue (N-butyl + octyl cyanoacrylate).

Methods:

Twelve PICCs of different brands and types were selected (11 made of polyurethane and one made of silicon). PICCs were glued onto artificial skin pads, slightly wetted with Earle solution. The pads were kept in an egg incubator at 34°C and 60% humidity, for up to twelve weeks. Possible signs of degradation were monitored by surface analyses and mechanical tests. Scanning electron microscopy observations, surface roughness measurements, pressure strength and uniaxial tests were performed.

Results:

Samples were analyzed after 4, 8 and 12 weeks of contact with the glue. No chemical reaction between the glue and the material of the catheters was evident. The mechanical strength of PICCs was consistently within the ranges of ISO standards. An expected increase in the stiffness of the samples covered with glue was observed in uniaxial tests. The silicon catheter was weaker than the polyurethane catheters and was damaged while trying to remove it from the pad for tests.

Conclusions:

The long-term use of N-butyl + octyl cyanoacrylate glue on polyurethane PICCs is not expected to be associated to any damage to the catheter.
Supervised preoperative forearm exercise to increase blood vessel diameter in patients requiring an arteriovenous access for hemodialysis: rationale and design of the PINCH trial
Authors: Wilschut Esther D. , Rotmans Joris I. , Bos Ernst Jan , van Zoest Daniëlle , Eefting Daniël , Hamming Jaap F. , van der Bogt Koen E.A.
Published: November 2017

Background:

Failure of maturation occurs in 30%-60% of arteriovenous fistula (AVF) creation for hemodialysis, with highest rates in distal radiocephalic fistulas. This is partly due to initial small blood vessel size with limited blood flow capacity. Forearm exercise has shown potential as stimulus for increasing blood vessel size in patients with end-stage renal disease (ESRD) and may promote maturation of AVFs in the upper limb when applied postoperatively. However, it is unknown if forearm exercise increases blood vessel size pre-operatively, which may contribute to more distal AVF creation and raise success rates of AVF surgery. This study will investigate these issues.

Methods and results:

The PINCH trial (refers to ‘pinching’) is an investigator-initiated, multicenter, single-blinded, randomized controlled trial with 1:1 randomization to perform supervised forearm exercises compared to no exercise 6 weeks pre-operatively before creation of an AVF. Forty patients receiving an AVF will be included. The main study endpoints are blood vessel diameter (cephalic or basilic vein and radial and ulnar artery), AVF surgical plan (radiocephalic or brachiobasilic/cephalic), and three-month (assisted) maturation rate. The burden of the performed forearm exercises will be evaluated using Kidney Disease Quality of Life (KDQOL-SF Dutch version 1.2) and exercise specific questionnaires. The PINCH trial is planned to start in November 2017. Enrollment is expected to be completed at the end of 2019.

Conclusions:

The PINCH study is the first trial to evaluate the effect of pre-operative, supervised forearm exercises on vein diameter and fistula maturation in hemodialysis patients.

An Archaeology of/for the Disenfranchised
Authors: Simandiraki-Grimshaw Anna
Published: November 2017

International debates and practices of current public archaeologies have reached the heritage sector in Greece, albeit with some delay. These are especially (but not exclusively) focused on young learner involvement, local community education and politicized relics. Public archaeology practitioners showcase much enthusiasm, imagination, and perseverance. However, the Greek archaeological establishment cannot be called ‘inclusive.’ In this article, I explore the systemic limitations to public archaeology in Greece, identify the audiences disenfranchised by current approaches, and discuss the means and reasons why this is happening. Finally, I propose solutions and suggest that Greek archaeology has significant potential to become a prime example of inclusive public engagement.
A Mere Addition to Someone Else's Genealogy? Perceptions of Ancient Cultural Heritage, Public Policy, and Collective Memory in Portugal
Authors: Pappa Eleftheria
Published: November 2017

Debates on cultural heritage and collective memory emphasize the contested role of archaeology in national narratives to the exclusion of other parameters. Yet, cultural heritage can be made visible or remain invisible for reasons other than (un)conscious ideological preoccupations. The representation of the Phoenician archaeological record in Portugal is used to demonstrate that, despite its detachment from collective memory, the ancient cultural heritage can transcend its distance from the past, attaining significance within the contemporary social milieu. The Portuguese embrace their links with Phoenician cultural heritage, investing in academic research and cultural heritage. The corresponding ancient culture remains an adjunct of the archaeological evidence, researched and publicized, but not as an extension of the ‘collective self’ of modern society. Shifting this devoid-of-symbolic-meaning archaeological record onto the level of contemporary reality accords it visibility, even as the long-forgotten Phoenician origins of some still practiced traditions remain an unacknowledged, ‘invisible’ heritage.
Heritage Values and Communities: Examining Heritage Perceptions and Public Engagements
Authors: Apaydin Veysel
Published: November 2017

Communities construct themselves differently, depending on the diverse socio-political environments which they inhabit. This also impacts their worldviews and their perceptions of heritage. In addition, in nation states such as Turkey, heritage perceptions are shaped by state ideology through formal education, which often transfers one-sided and programmatic knowledge to students, mostly focusing on the official history of the state. As a result, communities are deprived of opportunities to learn about ‘other’ pasts, such as those concerned with prehistory and minorities in antiquity. Community archaeology projects and local museums hold an important role in closing the gap created by formal education methods, and can have a profound impact on community perceptions of the past. At the same time, the exchange of knowledge with communities can be troublesome. This article examines heritage perceptions and discusses the importance of public archaeology and local museums by comparing three different sites and their associated communities.
Archaeology, Shared Heritage, and Community at Akko, Israel
Authors: Killebrew Ann E. , DePietro Dana , Pangarkar Reema , Peleg Shelley-Anne , Scham Sandra , Taylor Evan
Published: November 2017

The international significance of Akko's heritage is best illustrated by the inscription of two UNESCO World Heritage sites in this town of just over 55,000 people. This article describes three projects that focus on the concept of a shared heritage at a World Heritage site in a multi-ethnic, multi-religious, diverse town situated in a region that continues to experience ongoing religious and ethnic conflict. The most recent, and still ongoing, effort to balance archaeology and community interests is the Tel Akko Total Archaeology Project. While attempting to incorporate community building through archaeology and dialog, the Total Archaeology approach described here aims for a socially just and inclusive archaeology that will benefit local community stakeholders rather than disenfranchise them. It also emphasizes the need for local perspectives and experiences to play an active role in the interpretation of the past.
The role and value of nurses in care provision: Views and expectations of Emirati Nationals in the western region of Abu Dhabi, United Arab Emirates
Authors: Brownie Sharon M. , Rossiter Rachel C. , Hamad Abeer Omar , Aqtash Salah
Published: November 2017

Background: Reliable health user information is needed to effectively organize nursing services and deliver quality patientcentered care. Nurse leaders of Al Gharbia Health Services (AGHS) noted that although budget data and general workforce information were readily available, detailed information about patient experiences, views, and expectations was lacking.Objective: This study aimed to obtain preliminary data regarding health and nursing service expectations of Emirati nationals in the remote western region of Abu Dhabi, United Arab Emirates (UAE).Methods: This study used qualitative descriptive methodology. Semi-structured interviews were conducted with a sample of Emirati families who had recently accessed AGHS. Interviews focused on service user understanding and expectations of the role of nurses, nursing services, and the health service overall.Results: Emirati nationals’ views and expectations regarding nurses’ role and function in the healthcare team were highlighted. Participants’ expectations and the attributes they valued were distributed across two distinct areas: clinical competence and the “softer” skills of compassion, caring, and respect.Conclusions: These findings facilitate understanding of the expectations of Emirati health service users. Importantly, the results counter regional perceptions of nursing under-valued as a servant role across the UAE and broader Gulf Cooperation Council region. The findings may inform a range of activities including: a large-scale survey regarding the views and expectations of Emirati health service users; pre-service nursing education and nursing in service development; and the recruitment of Emirati nationals to the nursing profession. Further investigation regarding perceptions and valuing of nursing within the Emirati community is warranted.

Published: November 2017

INTRODUCTION: Organizations are social systems where human resources are the most important factors. In recent years, healthcare employers have assigned a high priority to the recruitment of educated health professionals. The aim of our study was to identify the possible reasons behind the migration and attrition behaviour among Hungarian radiographers. We were interested whether the professional staff have ideas across borders which can be connected with attrition.MATERIAL & METHODS: In our cross-sectional retrospective study we used a self designed questionnaire and the Effort-Reward Imbalance (ERI) Questionnaire’s shortened version. Our target group were active radiographers with BSC radiography degree. The study sample counted 216 radiographers (n=216). For data analysis we used the SPSS 13.0. Variance analysis, paired sample T-test, Chi-square test, linear regression and descriptive statistics were used with the performed probability of 95% (p<0.05).RESULTS: 30.6% of responders (n=66) were considering working abroad, 40.3% (n=87) of responders remain in Hungary. At the age group of 20–30 we can observe significant relationship between the working opportunity abroad (p=0.001). The migration tendency was specific for radiographers with no children (n=54). We found a significant relationship between the working ability abroad and the radiographers’ years spent working in the healthcare system (p=0.008). 41.7% of respondents (n=90) think that it would be a favorable option to making a career change. We also found a significant relationship between the possibility of working abroad and the desire for higher wages and the lack of making career advancements as a radiographer (p=0.001; p=0.001).CONCLUSION: Correlation of our results with similar research was difficult because very few researchers put their interest into radiographers. In respect to other healthcare workers (eg.: nurses, physiotherapists) our result correlate well with the literature. Our research provides a broad view of the migration and attrition tendency among Hungarian radiographers and its underlying causes. According to our study changes should be implemented in the Hungarian system to keep the younger radiographers home.

This study aimed at analyzing the effect of exports on the economic growth of Brazilian microregions in 2010, based on the theoretical model developed by Feder (1982). The hypothesis is that the economic growth of a region results from the existing productivity differential between the exporting and non-exporting sectors, as well as from the externality generated by the exporting sector in the economy. To reach the results, a geographically weighted regression was estimated, identifying a positive effect on the externality in practically all the Brazilian microregions. Regarding productivity, its effect was limited to the microregions close to the two largest ports in Brazil.

Fluoroquinolone antibiotics such as ciprofloxacin are useful drugs against infections caused by Staphylococcus aureus and mutations in DNA gyrase which control bacterial DNA topology, can be one of the reason of occurrence resistance to this class of antibiotics. Therefore finding new mutations and study of the quinolone interaction with mutated GyrA can provide important issues for explanation resistance. In this study 5 ciprofloxacin resistance Staphylococcus aureus isolated among 50 collected S.aureus strains. By PCR testing, gyrA genes in resistance strains was amplified and nucleotide sequencing was done. Nucleotide sequences translate to amino acid sequences then by blastp homology between each GyrA mutant and reference GyrA were compared and mutations were recognized, at last molecular docking were done for GyrA protein and ciprofloxacin, based on free energy of binding decide if the mutations are responsible of resistance or not. The results show glutamic acid and threonine adjacent to each other in common positions 21-22, 32-33, 65-66, 84-85, 101-102, 106-107, 128-129 and 138-139 in all 5 strains were inserted . In order to finding association between mutations and ciprofloxacin resistance molecular docking by Molegro Virtual Docker 5.5 was done. Free energy of binding between reference GyrA- ciprofloxacin and mutant GyrA- ciprofloxacin were -92.3477 and -73.1642 respectively. We conclude different mutations can be affected structure of GyrA and make ciprofloxacin resistance. Finding these kinds of mutations are important and preventing them is indispensable.

In the transport companies listed on the Warsaw Stock Exchange there is a strong
tendency to maintain positive working capital. The method of comparative
analysis used in the article is based on purposive sampling cases. The aim of this
article is to empirically verify the hypothesis that large transport companies listed
on the Warsaw Stock Exchange maintain positive working capital.
Foreign Terrorist Fighters from the Perspective of Polish and European Criminal Law
Authors: Gacka Patryk
Published: November 2017

Foreign terrorist fighters represent one of the powerful threats to the security of states and humanity in the 21st century. Besides participating in the actions of the Islamic State, they also pose a significant danger when they return to their countries of origin to recruit new volunteers, radicalize local communities and actively partake in terrorist attacks. So as to increase the effectiveness of the fight against terrorism, states and international organizations (the EU, Council of Europe, UN) have been moving in the direction of criminalizing all manifestations of terrorist activity. The paper strives to achieve the following: providing a definition of foreign terrorist fighters; proffering a legal qualification of travel abroad undertaken by Polish citizens for terrorist purposes by reference to selected provisions of the Polish Criminal Code; conducting an analysis of the provisions of EU Directive of 15 March 2017 on combating terrorism against the backdrop of the criminalization of the activity of foreign terrorist fighters; comparing the Polish and European criminal legislations within the pertinent scope. De lege ferenda comments will be offered by means of a summary.

Realizamos una síntesis sobre el estado del conocimiento respecto a la reflexión en el aprendizaje: significado, utilidad y estrategias. A continuación presentamos un estudio de caso en la asignatura Estructuras 1 en el grado de Fundamentos de Arquitectura de la Universidad de Sevilla. Desde su implantación utilizamos el método de aprendizaje basado en problemas (ABP), uno de cuyos componentes básicos es la reflexión sobre el aprendizaje, que este caso incentivamos con informes de reflexión. En esta comunicación analizamos 62 informes de reflexión redactados por los estudiantes en varios cursos académicos aplicando técnicas de análisis cualitativo. Los resultados permiten detectar distintos enfoques en el trabajo y estudio de los estudiantes, así como fortalezas y debilidades en el trabajo en equipo. Hemos concluido que en nuestro contexto la autorregulación del aprendizaje se produce tanto individualmente como en equipo, y que el compromiso es un aspecto emocional muy relevante para los estudiantes. 

We do a synthesis about the state of knowledge related to reflection in learning: meaning, purpose and strategies. We introduce a case study in the subject Structures 1 in the Architecture degree at the University of Seville. In this subject we use problem-based learning (PBL), in which one basic component is reflection on learning, that in this case we put in to practice through reflective papers. We analyse 62 reflective papers written by the students from different academic years. We apply qualitative analysis techniques. The results allow us to detect different approaches in the students´ work and study, and strengths as well as weaknesses in teamwork. We have concluded that in our context learning self-regulation occurs individually as well as in team, and that engagement is an emotional aspect very relevant for students.

Structural adjustments in plants may occur in response to environmental constraints, which may influence plant growth and development, as well as patterns of species coexistence. The present study aimed to evaluate the plastic responses of Tibouchina clavata (Melastomataceae) occurring in two forest formations governed by different environmental conditions. Ten leaves of ten individuals were collected in each formation, for a total of n = 100 per area. as were stem samples, for measuring architectural, morphological and foliar traits. Environmental variables considered included edaphic nutrition, water availability and light radiation. The phenotypic plasticity index was calculated for each trait. Morphoanatomical traits varied among populations with greater emphasis on plant height and stem diameter, in contrast to the lower variation observed for leaf traits. Foliar morphoanatomy met the expected pattern for plants that grow under conditions of greater luminosity. Greater development of the aerial system (height and diameter of the stem) was observed in the plants of the ombrophilous forest, indicating that this growth is related to the soil fertility and water availability. The phenotypic plasticity index indicates low plasticity for T. clavata in the geographic distribution studied.

Background:

Exercise training can improve skeletal muscle metabolism in persons with multiple sclerosis (MS). However, quantification of exercise-mediated improvements in muscle metabolism has been limited, particularly in people with high levels of disability. We evaluated the effect of 9 weeks of antigravity treadmill training on muscle oxidative capacity and muscle endurance and assessed the relationship to walking function in a person with MS.

Methods:

One person with MS (Expanded Disability Status Scale score, 6.5) performed treadmill training for 24 minutes approximately twice weekly for 9 weeks (16 sessions) using an antigravity treadmill system. Before and after the intervention phase, we measured muscle oxidative capacity in the medial gastrocnemius using near-infrared spectroscopy after 15 to 20 seconds of electrical stimulation; muscle endurance in the medial gastrocnemius using accelerometer-based mechanomyography during 9 minutes of twitch electrical stimulation in three stages (3 minutes per stage) of increasing frequency (2, 4, and 6 Hz); muscle strength (plantarflexion) using a maximal voluntary contraction; and walking function using the Timed 25-Foot Walk test and the 2-Minute Walk Test.

Results:

Muscle oxidative capacity increased from 0.73 min−1 to 1.08 min−1 (48%). Muscle endurance increased from 75.9% to 84.0% at 2 Hz, from 67.8% to 76.2% at 4 Hz, and from 13.5% to 44.7% at 6 Hz. Maximal voluntary contraction decreased by 0.68 kg (15%), Timed 25-Foot Walk test speed decreased by 0.19 ft/s (20%), and 2-Minute Walk Test distance increased by 65 m (212%).

Conclusions:

Muscle oxidative capacity and muscle endurance, as well as walking function, improved in a person with MS after training on an antigravity treadmill.
