Authors: Oku Topal G. , Gülal E.
Published: November 2017

Abstract. The Disaster management aims to prevent events that result in disaster or to reduce their losses. Monitoring of engineering buildings, identification of unusual movements and taking the necessary precautions are very crucial for determination of the disaster risk so possible prevention could be taken to reduce big loss. Improving technology, increasing population due to increased construction and these areas largest economy lead to offer damage detection strategies. Structural Health Monitoring (SHM) is the most effective of these strategies. SHM research is very important to maintain all this structuring safely. The purpose of structural monitoring is determining in advance of possible accidents and taking necessary precaution. In this paper, determining the behaviour of construction using Global Positioning System (GPS) is investigated. For this purpose shaking table tests were performed. Shaking table was moved at different amplitude and frequency aiming to determine these movement with a GPS measuring system. The obtained data were evaluated by analysis of time series and Fast Fourier Transformation techniques and the frequency and amplitude values are calculated. By examining the results of the tests made, it will be determined whether the GPS measurement method can accurately detect the movements of the engineering structures.

Published: November 2017

Abstract. Interactive 3D architectural indoor design have been more popular after it benefited from Virtual Reality (VR) technologies. VR brings computer-generated 3D content to real life scale and enable users to observe immersive indoor environments so that users can directly modify it. This opportunity enables buyers to purchase a property off-the-plan cheaper through virtual models. Instead of showing property through 2D plan or renders, this visualized interior architecture of an on-sale unbuilt property is demonstrated beforehand so that the investors have an impression as if they were in the physical building. However, current applications either use highly resource consuming software, or are non-interactive, or requires specialist to create such environments. In this study, we have created a real-estate purposed low-cost high quality fully interactive VR application that provides a realistic interior architecture of the property by using free and lightweight software: Sweet Home 3D and Unity. A preliminary study showed that participants generally liked proposed real estate-purposed VR application, and it satisfied the expectation of the property buyers.
TANK INFORMATION SYSTEM (TIS): A CASE STUDY IN MIGRATING WEB MAPPING APPLICATION FROM FLEX TO DOJO FOR ARCGIS SERVER AND THEN TO OPEN SOURCE
Authors: Pulsani B. R.
Published: November 2017

Abstract. Tank Information System is a web application which provides comprehensive information about minor irrigation tanks of Telangana State. As part of the program, a web mapping application using Flex and ArcGIS server was developed to make the data available to the public. In course of time as Flex be-came outdated, a migration of the client interface to the latest JavaScript based technologies was carried out. Initially, the Flex based application was migrated to ArcGIS JavaScript API using Dojo Toolkit. Both the client applications used published services from ArcGIS server. To check the migration pattern from proprietary to open source, the JavaScript based ArcGIS application was later migrated to OpenLayers and Dojo Toolkit which used published service from GeoServer. The migration pattern noticed in the study especially emphasizes upon the use of Dojo Toolkit and PostgreSQL database for ArcGIS server so that migration to open source could be performed effortlessly. The current ap-plication provides a case in study which could assist organizations in migrating their proprietary based ArcGIS web applications to open source. Furthermore, the study reveals cost benefits of adopting open source against commercial software's.

Published: November 2017

Abstract. Road disturbances are occurring in our country due to the highway-weighted transportation. These disturbances are caused by human and natural causes. Disturbances in the roads have a negative effect on human life as well as damage to the vehicles. Regardless of how it occurs, it is important to quickly detect and eliminate roadside disturbances. The use of mobile devices has become widespread with developing technologies. Today, many sensors such as GPS and accelerometer are used to detect road disturbances on mobile devices. In this context, it is important to use mobile applications for fast and in-situ detection. In this study, it is investigated the use of mobile devices' location data received from GPS sensors with special mobile interfaces in gathering road data for road disturbances.

PRODUCING INFORMATION FOR CORINE DATABASE BY USING CLASSIFICATION METHOD: A CASE STUDY OF SAZLIDERE BASIN, ISTANBUL
Authors: Sarıyılmaz F. B. , Musaoğlu N. , Uluğtekin N.
Published: November 2017

Abstract. The Sazlidere Basin is located on the European side of Istanbul within the borders of Arnavutkoy and Basaksehir districts. The total area of the basin, which is largely located within the province of Arnavutkoy, is approximately 177 km2. The Sazlidere Basin is faced with intense urbanization pressures and land use / cover change due to the Northern Marmara Motorway, 3rd airport and Channel Istanbul Projects, which are planned to be realized in the Arnavutkoy region. Due to the mentioned projects, intense land use /cover changes occur in the basin. In this study, 2000 and 2012 dated LANDSAT images were supervised classified based on CORINE Land Cover first level to determine the land use/cover classes. As a result, four information classes were identified. These classes are water bodies, forest and semi-natural areas, agricultural areas and artificial surfaces. Accuracy analysis of the images were performed following the classification process. The supervised classified images that have the smallest mapping units 0.09 ha and 0.64 ha were generalized to be compatible with the CORINE Land Cover data. The image pixels have been rearranged by using the thematic pixel aggregation method as the smallest mapping unit is 25 ha. These results were compared with CORINE Land Cover 2000 and CORINE Land Cover 2012, which were obtained by digitizing land cover and land use classes on satellite images. It has been determined that the compared results are compatible with each other in terms of quality and quantity.
AN EXTENDED SPECTRAL–SPATIAL CLASSIFICATION APPROACH FOR HYPERSPECTRAL DATA
Authors: Akbari D.
Published: November 2017

Abstract. In this paper an extended classification approach for hyperspectral imagery based on both spectral and spatial information is proposed. The spatial information is obtained by an enhanced marker-based minimum spanning forest (MSF) algorithm. Three different methods of dimension reduction are first used to obtain the subspace of hyperspectral data: (1) unsupervised feature extraction methods including principal component analysis (PCA), independent component analysis (ICA), and minimum noise fraction (MNF); (2) supervised feature extraction including decision boundary feature extraction (DBFE), discriminate analysis feature extraction (DAFE), and nonparametric weighted feature extraction (NWFE); (3) genetic algorithm (GA). The spectral features obtained are then fed into the enhanced marker-based MSF classification algorithm. In the enhanced MSF algorithm, the markers are extracted from the classification maps obtained by both SVM and watershed segmentation algorithm. To evaluate the proposed approach, the Pavia University hyperspectral data is tested. Experimental results show that the proposed approach using GA achieves an approximately 8 % overall accuracy higher than the original MSF-based algorithm.
A WEB API AND WEB APPLICATION DEVELOPMENT FOR DISSEMINATION OF AIR QUALITY INFORMATION
Authors: Şahin K. , Işıkdağ U.
Published: November 2017

Abstract. Various studies have been carried out since 2005 under the leadership of Ministry of Environment and Urbanism of Turkey, in order to observe the quality of air in Turkey, to develop new policies and to develop a sustainable air quality management strategy. For this reason, a national air quality monitoring network has been developed providing air quality indices. By this network, the quality of the air has been continuously monitored and an important information system has been constructed in order to take precautions for preventing a dangerous situation. The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.
INVESTIGATION OF THE RELATIONSHIP BETWEEN IONOSPHERIC TEC
ANOMALY VARIATIONS AND FAULT TYPES BEFORE THE EARTHQUAKES
Authors: Ulukavak M. , Yalçınkaya M.
Published: November 2017

Abstract. Earthquakes are natural phenomena that shake the earth and cause many damage. Since the time of arrival of the earthquakes cannot be determined directly, some signs before the earthquake should be examined and interpreted by examining the environmental changes. One of the methods used for this is monitoring the ionospheric total electron content (TEC) changes in total electron content unit (TECU). GPS satellites have begun to be used as a means of monitoring ionospheric TEC anomalies before earthquakes since they began to be used as sensors around the world. In this study, three fault type (normal, thrust and strike-slip faulting) of 28 earthquakes with a magnitude greater than 7 (Mw) and the percentage changes of TEC anomalies before the earthquakes were investigated. The ionospheric TEC anomalies before the earthquake were calculated according to the 15-day running median statistical analysis method. Different solar and geomagnetic indices have been investigated to determine the active space weather conditions and quiet days before and after the earthquake. The TEC anomalies were determined during the quiet days before the earthquake by comparing the ionospheric anomalies that occurred before the earthquake after the determination of quiet days with the indices of the space weather conditions. The results show that there is a relationship between fault type and the earthquake precursor percentage changes and were determined as 47.6 % TECU for regions where normal faulting, 50.4 % TECU for regions where thrust faulting, and 44.2 % TECU for regions where strike-slip faulting occurred, respectively.
GLOBALLY-APPLICABLE PREDICTIVE WILDFIRE MODEL   A TEMPORAL–SPATIAL GIS BASED RISK ANALYSIS USING DATA DRIVEN FUZZY LOGIC FUNCTIONS
Authors: van den Dool G.
Published: November 2017

Abstract. This study (van den Dool, 2017) is a proof of concept for a global predictive wildfire model, in which the temporal–spatial characteristics of wildfires are placed in a Geographical Information System (GIS), and the risk analysis is based on data-driven fuzzy logic functions. The data sources used in this model are available as global datasets, but subdivided into three pilot areas: North America (California/Nevada), Europe (Spain), and Asia (Mongolia), and are downscaled to the highest resolution (3-arc second). The GIS is constructed around three themes: topography, fuel availability and climate. From the topographical data, six derived sub-themes are created and converted to a fuzzy membership based on the catchment area statistics. The fuel availability score is a composite of four data layers: land cover, wood loads, biomass, biovolumes. As input for the climatological sub-model reanalysed daily averaged, weather-related data is used, which is accumulated to a global weekly time-window (to account for the uncertainty within the climatological model) and forms the temporal component of the model. The final product is a wildfire risk score (from 0 to 1) by week, representing the average wildfire risk in an area. To compute the potential wildfire risk the sub-models are combined usinga Multi-Criteria Approach, and the model results are validated against the area under the Receiver Operating Characteristic curve.

MULTIPLE AND SINGLE GREEN AREA MEASUREMENTS AND CLASSIFICATION USING PHANTOM IMAGES IN COMPARISON WITH DERIVED EXPERIMENTAL LAW
Authors: Abu-Zaid N. A. M.
Published: November 2017

Abstract. In many circumstances, it is difficult for humans to reach some areas, due to its topography, personal safety, or security regulations in the country. Governments and persons need to calculate those areas and classify the green parts for reclamation to benefit from it.To solve this problem, this research proposes to use a phantom air plane to capture a digital image for the targeted area, then use a segmentation algorithm to separate the green space and calculate it's area. It was necessary to deal with two problems. The first is the variable elevation at which an image was taken, which leads to a change in the physical area of each pixel. To overcome this problem a fourth degree polynomial was fit to some experimental data. The second problem was the existence of different unconnected pieces of green areas in a single image, but we might be interested only in one of them. To solve this problem, the probability of classifying the targeted area as green was increased, while the probability of other untargeted sections was decreased by the inclusion of parts of it as non-green. A practical law was also devised to measure the target area in the digital image for comparison purposes with practical measurements and the polynomial fit.

Abstract. Social networks are the real social experience of individuals in the online environment. In this environment, people use symbolic gestures and mimics, sharing thoughts and content. Social network analysis is the visualization of complex and large quantities of data to ensure that the overall picture appears. It is the understanding, development, quantitative and qualitative analysis of the relations in the social networks of Graph theory. Social networks are expressed in the form of nodes and edges. Nodes are people/organizations, and edges are relationships between nodes. Relations are directional, non-directional, weighted, and weightless. The purpose of this study is to examine the effects of social networks on the evaluation of person data with spatial coordinates. For this, the cluster size and the effect on the geographical area of the circle where the placements of the individual are influenced by the frequently used placeholder feature in the social networks have been studied.

Published: November 2017

Abstract. The aim of this study is to conduct accuracy analyses of Land Use Land Cover (LULC) classifications derived from Sentinel-2 and Landsat-8 data, and to reveal which dataset present better accuracy results. Zonguldak city and its near surrounding was selected as study area for this case study. Sentinel-2 Multispectral Instrument (MSI) and Landsat-8 the Operational Land Imager (OLI) data, acquired on 6 April 2016 and 3 April 2016 respectively, were utilized as satellite imagery in the study. The RGB and NIR bands of Sentinel-2 and Landsat-8 were used for classification and comparison. Pan-sharpening process was carried out for Landsat-8 data before classification because the spatial resolution of Landsat-8 (30m) is far from Sentinel-2 RGB and NIR bands (10m). LULC images were generated using pixel-based Maximum Likelihood (MLC) supervised classification method. As a result of the accuracy assessment, kappa statistics for Sentinel-2 and Landsat-8 data were 0.78 and 0.85 respectively. The obtained results showed that Sentinel-2 MSI presents more satisfying LULC images than Landsat-8 OLI data. However, in some areas of Sea class Landsat-8 presented better results than Sentinel-2.

Abstract. The darkening effects of biological impurities on ice and snow have been recognised as a control on the surface energy balance of terrestrial snow, sea ice, glaciers and ice sheets. With a heightened interest in understanding the impacts of a changing climate on snow and ice processes, quantifying the impact of biological impurities on ice and snow albedo (bioalbedo) and its evolution through time is a rapidly growing field of research. However, rigorous quantification of bioalbedo has remained elusive because of difficulties in isolating the biological contribution to ice albedo from that of inorganic impurities and the variable optical properties of the ice itself. For this reason, isolation of the biological signature in reflectance data obtained from aerial/orbital platforms has not been achieved, even when ground-based biological measurements have been available. This paper provides the cell-specific optical properties that are required to model the spectral signatures and broadband darkening of ice. Applying radiative transfer theory, these properties provide the physical basis needed to link biological and glaciological ground measurements with remotely sensed reflectance data. Using these new capabilities we confirm that biological impurities can influence ice albedo, then we identify 10 challenges to the measurement of bioalbedo in the field with the aim of improving future experimental designs to better quantify bioalbedo feedbacks. These challenges are (1) ambiguity in terminology, (2) characterising snow or ice optical properties, (3) characterising solar irradiance, (4) determining optical properties of cells, (5) measuring biomass, (6) characterising vertical distribution of cells, (7) characterising abiotic impurities, (8) surface anisotropy, (9) measuring indirect albedo feedbacks, and (10) measurement and instrument configurations. This paper aims to provide a broad audience of glaciologists and biologists with an overview of radiative transfer and albedo that could support future experimental design.
Aero-elastic Wind Turbine Design with Active Flaps for AEP
Maximization
Authors: McWilliam Michael K. , Barlas Thanasis K. , Madsen Helge A. , Zahle Frederik
Published: November 2017

Abstract. In optimal wind turbine design, there is a compromise between maximizing the energy producing forces and minimizing the absolute peak loads carried by the structures. Active flaps are an attractive strategy because they give engineers greater freedom to vary the aerodynamic forces under any condition. Flaps can be used in a variety of different ways (i.e. reducing fatigue, peak loads etc.), however this article focuses on how quasi-static actuation as a function of mean wind speed can be used for Annual Energy Production (AEP) maximization. Numerical design optimization of the DTU 10 MW Reference Wind Turbine (RWT), with the HAWTOpt2 framework, was used to both find the optimal flap control strategy and the optimal turbine designs. The research shows that active flaps can provide a 1 % gain in AEP for aero-structurally optimized blades in both add-on (i.e. the flap is added after the blade is designed) and integrated (i.e. the blade design and flap angle is optimized together) solutions. The results show that flaps are complementary to passive load alleviation because they provide high-order alleviation, where passive strategies only provide linear alleviation with respect to average wind speed. However, the changing loading from the flaps further complicates the design of torsionally active blades, thus, integrated design methods are needed to design these systems.

O objetivo deste texto é estudar a constituição do olhar holandês a partir da visualização da paisagem colonial nas telas dos pintores Frans Post e Albert Eckhout. Um dos temas escolhidos para este trabalho foi o estudo do conceito de memória por meio das imagens do Brasil holandês, sabe-se que os artistas envolvidos no projeto colonial neerlandês buscaram entender este “mundo” pelos conceitos naturais e humanos representados nas pinturas destes. Eles foram os primeiros pintores a retratarem as paisagens americanas com sua gente. Para compreender tal visão é de suma importância estudar as imagens imaginárias que foram erigidas por Post e Eckhout. Vamos utilizar primordialmente como fonte (visual) de pesquisa duas telas: O carro de bois de 1638 e Mameluca de 1643, todas as imagens foram produzidas quando Frans Post e Albert Eckhout estiveram na América holandesa integrando a comitiva do governador João Maurício de Nassau. Buscaremos trabalhar com uma metodologia que privilegie a leitura de fontes primárias visuais para assim compreendermos a paisagem colonial.

In general, the construction industry is a great generator of RCCs, and there is still a lack of public policies at federal, state and municipal levels to help managers create structures capable of effective management while minimizing the impacts of waste on the environment . It was possible to perceive the lack of incentive of the recycling process in the municipalities, which could be a facilitator in the management of RCCs.

Purpose:

To evaluate the outcomes of myopic small incision lenticule extraction (SMILE) monovision in presbyopic patients.

Methods:

This study included 49 presbyopic patients older than 45 years seeking surgical correction of myopia or myopic astigmatism who underwent bilateral SMILE with planned monovision in the SMILE Eyes Clinic Linz, Austria. Target refraction was plano for dominant (distance) eyes and ranged between -1.25 and -0.50 D for nondominant (near) eyes. Best-corrected distance visual acuity, uncorrected distance visual acuity (UDVA), uncorrected near visual acuity, as well as spectacle dependence were assessed after a mean postoperative period of 7.2 ± 4.8 months.

Results:

Mean age was 49 ± 3 years and female to male ratio was 30:19. Distance eyes achieved a spherical equivalent correction of ±0.50 D from target refraction in 80% of patients and 96% were within ±1.0 D. Binocular UDVA of 20/20 or better was achieved by 90% of patients and all patients achieved 20/25 or better. The proportion of patients with a binocular UDVA of 20/20 or better who could read J2 or better amounted to 84%. Complete spectacle independence was achieved by 84% of patients and independence from reading glasses was achieved in 92% of cases. No patient requested refractive enhancement or monovision reversal.

Conclusions:

This first evaluation of SMILE monovision endorses the approach as a safe and effective option for the correction of presbyopia in myopic patients seeking refractive surgery.

Purpose:

To report the results of our sequential intravitreal (IV) tissue plasminogen activator (tPA), pneumatic displacement (PD), and IV anti-vascular endothelial growth factor (VEGF) treatment in patients with neovascular age-related macular degeneration (nAMD)-related submacular hemorrhage (SMH).

Methods:

A total of 16 eyes of 16 patients with SMH of less than 15 days duration were included in this retrospective pilot study. The tPA was applied on the day of diagnosis, and PD was performed the following day. Patients received 3 consecutive monthly IV injections of ranibizumab starting from 15 days after PD. During the follow-ups, additional ranibizumab treatment was performed if persistent macular or recurrent subretinal or intraretinal fluid hemorrhage was observed.

Results:

The mean central retinal thickness was 489 ± 92 μm (311-621 μm) at the time of diagnosis, 324 ± 56 μm (209-409 μm) at the first month, 262 ± 48 μm (197-364 μm) at 3 months, 248 ± 40 μm (190-334 μm) at 6 months, and 253 ± 41 μm (192-356 μm) at the last control (p<0.01). The mean best-corrected visual acuity was 2.08 ± 0.79 logMAR (0.7-3.0 logMAR) at baseline, 1.41 ± 0.70 logMAR (0.56-2.50 logMAR) at the first month, 1.21 ± 0.66 logMAR (0.3-2.0 logMAR) at 3 months, 1.14 ± 0.77 logMAR (0.2-2.50 logMAR) at 6 months, and 1.09 ± 0.73 logMAR (0.3-2.50 logMAR) at the last follow-up (p<0.01).

Conclusions:

Sequential IV tPA, PD, and IV anti-VEGF treatments for SMH in patients with nAMD is effective. However, further studies are needed to establish the best treatment algorithm for SMH in patients with nAMD.

Published: November 2017

Introduction:

As an essential step of total hip arthroplasty (THA), an effective and secure skin closure technique after primary THA is important. Metallic staples closure and subcuticular suture are the 2 common techniques for skin closure. However, which closure technique is the optimal skin-closure method remains unclear. The purpose of this prospective randomised clinical study was to compare the clinical outcomes and costs between staples and subcuticular suture techniques.

Methods:

In this clinical study, 165 patients who underwent primary unilateral THA through a posterolateral approach from August 2014 to May 2015 were included. According to skin closure technique, the patients were randomised into staples group (interrupted suture with staples, 83 cases) and sutures group (running 4-0 absorbable subcuticular suture, 82 cases). The same operative and perioperative care were provided to all patients. The surgical site infections (SSIs) rate, closure time, time to dry wounds and postoperative hospital stay were recorded and compared. Besides, cosmetic results and patient’s satisfaction were evaluated with Hollander wound evaluation score (HWES) and VAS score at postoperative 3 months follow-up respectively. Relative total costs were recorded as well.

Results:

It was shown that no infections developed in sutures group, while 2 postoperative superficial infections (2.4%) occurred in the staples group. There was a statistically significant difference in the time to dry surgical incisions and postoperative hospital stay favoring sutures (4.8 vs. 5.0 days, p = 0.028; 6.0 vs. 12.0 days, p<0.001, respectively). The cutaneous incision closure using staples consumed significantly less time than that with subcuticular suture (24.7 vs. 357.7 seconds, p<0.001). Moreover, there was no significant difference in HWES and patient’s satisfaction between the 2 groups. Finally, the application of subcuticular suture saved an average of $82.2 per case.

Conclusions:

Closure with running subcuticular suture is cheaper and appears to have a clinical advantage when compared with metallic staples skin closure in primary THA surgery. However, additional operating time may be incurred.

Authors: Yildiz Cemil , Erdem Yusuf , Koca Kenan
Published: November 2017

Introduction:

The aim of this study was to report the clinical and radiological outcomes for 21 patients (28 hips) treated for osteonecrosis of the femoral head using the lightbulb technique, a nonvascularised bone grafting technique.

Methods:

The study group included 14 men and 7 women, with a mean age of 33.2 (range 22-50) years, presenting with avascular necrosis of the femoral head of stage 4a or earlier, according to the Steinberg classification. Patients were treated using the nonvascularised lightbulb bone grafting technique. The primary clinical outcome was the Harris Hip Scores (HHS), while primary outcomes of treatment effectiveness and disease progression were based on radiographic evidence of disease progression and the need for total hip replacement. The rate of treatment success and failure was evaluated using the Kaplan-Meier survival analysis.

Results:

The mean HHS increased from 52.66 to 74.33 after treatment, with excellent-to-good outcomes obtained in 21 (75%) of the cases. Fair-to-poor results were obtained in 7 (25%) of the cases, with total hip arthroplasty subsequently required in 5 of these cases. The radiological failure rate was 50% among cases treated in Steinberg stage 1 (1/2), 42% in stage 3 (5/12), and 100% in stage 4 (2/2).

Conclusions:

The lightbulb technique can provide a clinically acceptable rate of successful treatment of osteonecrosis of the femoral head when used in the early stages of the disease, prior to collapse of the femoral head.
The influence of hemodialysis membrane permeability on serum procalcitonin values in patients on maintenance hemodialysis
Authors: Aatif Taoufiq , Zajjari Yassir , Jeaidi Anas
Published: November 2017

Background:

Procalcitonin (PCT) has emerged as a marker of infection and it could be useful for detection of systemic bacterial infections in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). The aim of this study was to assess the influence of HD membrane permeability to PCT serum levels in noninfected HD patients on maintenance HD.

Methods:

In a prospective comparative study, we measured PCT serum levels and C reactive protein (CRP) before and after HD in 36 sessions (18 sessions of HD with low-flux = Group L; and 18 sessions with high flux membranes = Group H), in 18 chronic HD patients without history of infection.

Results:

Sessions of HD by high-flux membranes (Group H) displayed median PCT values that were significantly decreased after dialysis (0.21 ng/mL [0.13-0.41] vs. 0.18 ng/mL [0.10-0.24], p <0.001) but median PCT significantly increased after HD sessions by low-flux membranes (Group L) (0.21 ng/mL [0.14-0.33] vs. 0.25 ng/mL [0.14-0.36]; p = 0.008). CRP values were significantly increased after HD in both groups. CRP correlated with PCT values only in group H before HD (r = 0.49; p = 0.36).

Conclusions:

PCT represents a useful diagnostic marker for systemic bacterial infection. However, there is a need for specific reference ranges to be developed in patients with renal failure undergoing HD; also, PCT serum levels must be interpreted according to the HD membrane permeability.
