Abstract
OBJECTIVE To perform the first investigation of the role of immune-inflammatory-nutritional status (INS) on oncological outcomes in patients undergoing open radical cystectomy (ORC) for urothelial carcinoma (UC). MATERIALS AND METHODS The records of consecutive patients who underwent ORC for non-metastatic bladder cancer between 2009 and 2020 were retrospectively analyzed. Neoadjuvant chemotherapy, non-urothelial tumor biology, and absence of oncological follow-up were exclusion criteria. Systemic immune-inflammatory index (SII) and Prognostic Nutritional Index (PNI) values were calculated and optimal cut-off values for these were used to designate four subgroups: "high SII-high PNI", "low SII-high PNI", "low SII-low PNI", and "high SII-low PNI". The Low SII-high PNI INS group had best overall survival (OS) rate while the remainder were included in non-favorable INS group. Survival curves were constructed, and a multivariate Cox regression model was used for OS and recurrence-free survival (RFS). RESULTS After exclusions, the final cohort size was 173 patients. The mean age was 64.31 ± 8.35 and median follow-up was 21 (IQR: 9-58) months. Optimal cut-off values for SII and PNI were 1216 and 47, respectively. The favorable INS group (low SII-high PNI, n = 89) had the best OS rate (62.9%). Multivariate Cox regression analysis indicated that non-favorable INS (n = 84) was a worse independent prognostic factor for OS (HR: 1.509, 95%CI: 1.104-3.145, p = 0.001) and RFS (HR: 1.285; 95%CI: 1.009-1.636, p = 0.042). CONCLUSION Preoperative assessment of INS may be a useful prognostic panel for OS and RFS in patients who had ORC for UC.

Abstract
Simple Summary Blood is considered a rich reservoir of biomarkers for disease diagnosis. Surface-enhanced Raman scattering (SERS) is known for its high sensitivity and has been successfully employed to differentiate blood samples from cancer patients versus healthy individuals. Different from previous reports, this study aims at investigating the reliability of the observed results by varying several parameters influencing the observed spectra. Thus, blood taken from 30 healthy individuals as the control group, 30 patients with different types of cancers, and 15 patients with various types of chronic diseases were used in the study. The results revealed that spectral differences in the cancer group was directly related to the presence of cancer-related biomarkers. Although data were obtained from only small group of patients, the recorded sensitivity and specificity values clearly show the power of the technique to detect cancer. Abstract Blood is a vital reservoir housing numerous disease-related metabolites and cellular components. Thus, it is also of interest for cancer diagnosis. Surface-enhanced Raman spectroscopy (SERS) is widely used for molecular detection due to its very high sensitivity and multiplexing properties. Its real potential for cancer diagnosis is not yet clear. In this study, using silver nanoparticles (AgNPs) as substrates, a number of experimental parameters and scenarios were tested to disclose the potential for this technique for cancer diagnosis. The discrimination of serum samples from cancer patients, healthy individuals and patients with chronic diseases was successfully demonstrated with over 90% diagnostic accuracies. Moreover, the SERS spectra of the blood serum samples obtained from cancer patients before and after tumor removal were compared. It was found that the spectral pattern for serum from cancer patients evolved into the spectral pattern observed with serum from healthy individuals after the removal of tumors. The data strongly suggests that the technique has a tremendous potential for cancer detection and screening bringing the possibility of early detection onto the table.

Abstract
Management of nanomaterials and nanosafety data needs to operate under the FAIR (findability, accessibility, interoperability, and reusability) principles and this requires a unique, global identifier for each nanomaterial. Existing identifiers may not always be applicable or sufficient to definitively identify the specific nanomaterial used in a particular study, resulting in the use of textual descriptions in research project communications and reporting. To ensure that internal project documentation can later be linked to publicly released data and knowledge for the specific nanomaterials, or even to specific batches and variants of nanomaterials utilised in that project, a new identifier is proposed: the European Registry of Materials Identifier. We here describe the background to this new identifier, including FAIR interoperability as defined by FAIRSharing, identifiers.org, Bioregistry, and the CHEMINF ontology, and show how it complements other identifiers such as CAS numbers and the ongoing efforts to extend the InChI identifier to cover nanomaterials. We provide examples of its use in various H2020-funded nanosafety projects.

Abstract
Surface-enhanced Raman spectroscopy (SERS) is a very sensitive technique offering unique opportunities for detection and identification of molecules and molecular structures at extremely low concentrations even in complex sample matrixes. Since a nanostructured noble metal surface is required for the enhancement of Raman scattering, the acquired spectral information naturally originates from nanometer size domains making it a nanospectroscopic technique by breaking the diffraction limit of light. In this review, first Raman spectroscopy, its comparison to other related techniques, its modes and instrumentation are briefly introduced. Then, the SERS mechanism, substrates and the parameters influencing a SERS experiment are discussed. Finally, its applications in pharmaceuticals including drug discovery, drug metabolism, multifunctional chemo-photothermal-therapy-delivery-release-imaging, drug stability and drug/metabolite detection in complex biological samples are summarized and elaborated.

Abstract
Extracting molecular level label-free information from complex biological processes for a range of purposes including disease diagnosis and microbial identification and discrimination is always a challenging task. This is mostly due to lack of a technique providing rich molecular information with a high spatial and temporal resolution properties. Two surface-enhanced vibrational spectroscopic (SEVS) techniques, surface-enhanced Raman scattering (SERS) and surface-enhanced infrared absorption spectroscopy (SEIRAS), are recently attracting considerable attention to study biosystems at an interface since they can satisfy these requirements to a certain level by providing rich intrinsic molecular information from molecules and molecular systems in a close proximity of nanostructured noble metal surfaces. In this study, these two surface-enhanced vibrational spectroscopic techniques are comparatively evaluated for the discrimination and identification of Candida albicans (C. albicans), Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) by paying attention to the source of the observed spectral pattern. The citrate-reduced colloidal silver nanoparticles (AgNPs) were used as substrates. The results show that the SEIRAS provides very rich molecular information about the biomolecular species adsorbed onto AgNPs similar to the case of SERS. The discrimination power of SEIRAS is much improved compared to FTIR demonstrated by PCA analysis. This study suggests that SEIRAS can be a potential technique for microbial analysis.

Abstract
In this study, the acidity of urazole (pKa 5-6) was exploited to fabricate a hydrogel in two simple and scalable steps. Commercially available poly(hexamethylene)diisocyanate was used as a precursor to synthesize an urazole containing gel. The formation of urazole was confirmed by FT-IR and 1H-NMR spectroscopy. The hydrogel was characterized by microscopy imaging as well as spectroscopic and thermo-gravimetric analyses. Mechanical analysis and cell viability tests were performed for its initial biocompatibility evaluation. The prepared hydrogel is a highly porous hydrogel with a Young's modulus of 0.91 MPa, has a swelling ratio of 87%, and is capable of exchanging ions in a medium. Finally, a general strategy was demonstrated to embed urazole groups directly into a crosslinked material.

Abstract
BACKGROUND AND STUDY AIMS To investigate the clinical and laboratory characteristics of the cases with high lipase levels in the course of COVID-19. PATIENTS AND METHODS Hospital records of all cases, where lipase levels were measured, and the reverse transcriptase-polymerase chain reaction test due to SARS-CoV-2 was found positive, were retrospectively investigated. Of 127 COVID-19 patients tested for lipase, 20 (15.7%) had serum lipase levels above the upper laboratory limit. The patient group with the "high lipase level" was created from these subjects, and the rest constituted the "control" group. RESULTS While body mass index (BMI) levels were higher in the high lipase group, (p=0.014), the number of those with pre-existing diabetes mellitus (DM) was also found higher in the high lipase group than the controls (p=0.002). The history of DM was detected to increase the risk of developing high lipase level 4.63 times higher. Only two patients were diagnosed with acute pancreatitis (AP). While oxygen saturations on admission (p=0.019) and discharge (p=0.011) were lower in the high lipase group than the controls, amylase (p<0.001), C-reactive protein (CRP) (p=0.002) and D-dimer (p=0.004) levels were found higher. In addition, more patients required the treatment in intensive care unit in the high lipase group, compared to the controls (p=0.027). Accordingly, time of hospital stay became also prolonged (p=0.003). CONCLUSIONS Pancreatic injuries or even AP may develop during SARS-CoV-2 infection, especially in those with pre-existing DM. Monitoring of pancreatic enzymes is important in COVID-19 patients, especially with pre-existing DM.

Abstract
OBJECTIVES Immune thrombocytopenia (ITP) is an autoimmune disease with heterogeneous background. FCGR2C mutations were defined in one third of the patients but genetic players have not been fully elucidated yet. Although childhood ITP present as benign, ITP in adulthood is chronic disease with treatment challenges. This study aimed to focus on adult ITP patients using a whole genome genotyping that is valuable approach to identify the responsible genomic regions for the disease. METHODS Herein 24 adult primary-refractory for ITP patients were evaluated using HumanCytoSNP12BeadChip,Illumina. Forty-six age and sex matched healthy individuals, and ptients awith nonhematological conditions were analyzed as controls. Identified CNV regions were verified by qRTPCR. T-cell receptor beta and delta (TCRB/TCRG) clonality were assessed by heteroduplex analysis in mosaic cases. RESULTS Several CNV losses and gains were defined (losses:2q,7q,17q,19p, and gains: 1q,2p,3q,4q,7q,10q,12p,13q,14q,15q,17p,20q,21p,22q,Xp). Mosaic changes of different sizes (0.2-17.77Mb) were identified in five patients and three of them showed clonality. CNV regions that were unique to ITP patients were identified for the first time and among these genes, those related to immune regulation, and cellular trafficking were noteworthy. Conclusion: Identified CNV regions harbor several candidate genes, the functions of which might shed light on the pathogenesis of chronic ITP.

Abstract
Purpose: The aim of this study was to assess the effect of the Er:YAG laser on the clinical
success of a hydrophilic fissure sealant over 12 months. Subject and methods: This study was conducted on 132 permanent first molars from 44 (19 girls and 25
boys) patients aged 7-11 years. The teeth were divided into three groups. The first
group (Group A-control) of teeth were etched with phosphoric acid, the second
group of teeth (Group L) were etched with an Er:YAG laser, and the third group of
teeth (Group A+L) were etched with both the Er:YAG laser and phosphoric acid.
Clinical evaluations were performed at baseline and at 3-, 6-, 9- and 12-month
follow-up visits. The data were analyzed with Pearson chi-square tests, Cochran Q
tests and Kaplan-Meier analysis. Results: At the end of the 12 months, total retention rates were 72.7%, 59.1%, and 65.9% in
the acid group, the laser group and the laser and acid group, respectively. Although
there was no statistically significant difference between group retention rates
(p>0.05), the lowest retention rate was found in the laser group at the end of the
12-month follow-up period. No new caries were observed in any group during the
study period. Conclusion: Etching with the Er:YAG laser, phosphoric acid or a combination of both methods
provided similar results for the clinical success of hydrophilic based fissure sealant.

Abstract
1. There is no current data about the genotypes of Marek's disease virus (MDV) in Turkish poultry flocks; hence, this study was performed to analyse CVI988/Rispens, turkey herpesvirus (HVT) vaccine viruses and MDV field viruses as well as to perform phylogenetic analysis of MDV in Turkish layer chickens. 2. In 2017 and 2018, a total of 602 spleen samples from 49 layer flocks were collected from the Marmara, West Black Sea and Aegean regions. DNA was extracted from the spleen samples and the samples were analysed by real-time PCR probe assay to detect CVI988/Rispens and HVT vaccine viruses and MDV field strains. Samples found positive for MDV by real-time PCR were subjected to PCR using the Meq gene primers for phylogenetic analysis. 3. Amongst 49 flocks, virulent MDV was detected in nine flocks. CVI988/Rispens and HVT vaccine strains were detected in 47 flocks and HVT in all 49 flocks. Splenomegaly, hepatomegaly and tumours in the oviduct were observed in chickens of affected flocks. Virulent MDV was detected in 120 out of 602 spleen samples. Sequencing and phylogenetic analyses showed that MDVs detected in this study were closely related to MDV strains from Italy, Poland, Saudi Arabia, Iraq, India and China but showed diversity with MDV strains from Egypt and Hungary. Multiple sequence analysis of the Meq protein revealed several point mutations in deduced amino acid sequences. Interestingly, CVI988/Rispens vaccine virus from China (AF493555) showed mutations at position 66 (G66R) and 71 (S66A) along with two other vaccine strains from China (GU354326.1) and Russia (EU032468.1), in comparison with the other vaccine strain CVI988/Rispens (DQ534538). The molecular analyses of the Meq gene suggested that Turkish field strains of MDV are in the class of virulent or very virulent pathotypes. 4. The results have shown that MDV still affects poultry health, and the phylogenetic and amino acid variation data obtained will help in vaccination and control strategies.

Abstract
The emergence of new infectious bursal disease virus (IBDV) variants can threaten poultry health and production all over the world causing significant economic losses. Therefore, this study was performed to determine IBDV molecular epidemilogy, VP2 gene variation, and corresponding pathological lesions in IBDV infected chickens in Turkey. For this, 1855 bursa of Fabricius samples were collected from 371 vaccinated broiler flocks. Atrophia and haemorrhages were seen in the bursa Fabricius of very virulent IBDV (vvIBDV) infected chickens. Partial VP2 gene was sequenced and phylogenetic, recombination, and evolutionary analyses were performed. 1548 (83.5%) out of 1855 of bursa of Fabricius samples were IBDV positive and 1525 of those could be sequenced. The recombination analysis did not detect occurrence of any recombination event among the Turkish strains. Among 1525 sequenced samples, 1380 of them were found to be classical strains. Among 1380 classical strains, 1317 were similar to IBDV 2512, 11 to Faragher 52/70, 40 to 228 E, and 12 to Lukert strain. Out of 1525 reverse transcriptase ploymerase chain reaction positive samples, 144 of them were found to be similar to vvIBDV-VP2 gene reported to GenBank previously. The phylogenetic tree performed on a broad sequence dataset demonstrated grouping of vvIBDV Turkish strains in three different clusters, including sequences collected also from Iraq and Kuwait (Cluster 1), Indian (Cluster 2), and a distinct Turkish-only cluster (Cluster 3). The evolutionary rate estimation on branches/clades including Turkish strain mirrored the expected one for RNA viruses and no significant differences were found among different considered branches. In conclusion, results of this study indicate that vvIBDV strains similar to those circulating in various countries in the Middle East are present and undergoing evolution in chickens from Turkish broiler flocks. This point needs to be taken into account in planning adequate control strategies.

Abstract
PURPOSE Acromegaly is a rare disorder existed in the result of overproduction of growth hormone (GH). The disorder is associated with increased cardiovascular risk factors and metabolic abnormalities. Urotensin II (UII), a secreted vasoactive peptide hormone, belonging somatostatin superfamily, plays an essential role in atherosclerosis and glucose metabolism. The aim of this study was to ascertain whether circulating UII levels are altered in subjects with acromegaly, and to describe the relationship between UII and hormonal or cardiometabolic parameters. METHODS This cross-sectional study included 41 subjects with active acromegaly, 28 subjects with controlled acromegaly, and 37 age- and BMI-matched controls without acromegaly. Hormonal and metabolic features of the subjects as well as carotid intima media thickness (cIMT) and epicardial fat thickness (EFT) were defined. Circulation of UII levels was determined via ELISA. RESULTS Both active and controlled acromegalic subjects showed a significant elevation of circulating levels of UII with respect to controls. There was no remarkable difference in circulating levels of UII between active and controlled acromegalic groups. Both cIMT and EFT were remarkably increased in acromegaly subjects comparing to controls. UII positively correlated with cIMT, EFT, BMI, and HOMA-IR. There was no correlation between UII and GH, insulin-like growth factor-1. According to the results obtained from regression models, UII levels independently predicted cIMT and EFT. CONCLUSION Elevated UII levels are associated with severity of cardiovascular risk factors including cIMT and EFT in acromegalic subjects.

Abstract
Viral respiratory diseases, including avian metapneumovirus (aMPV), have a significant economic impact on poultry industries. The frequency and genotype diversity of aMPV in Turkish broiler flocks is not known at present. The aim of this study was to report the first molecular identification and phylogeny of aMPV, which is circulating in Turkish broiler flocks. Trachea tissue samples and tracheal swabs were collected from 110 broiler flocks distributed in different geographical regions in Turkey between March 2017 and March 2018. Detection of aMPV was confirmed with the use of universal reverse transcriptase (RT) PCR, and eight (7.2%) broiler farms were positive for aMPV. Sequence analysis of the G gene revealed the exclusive presence of subtype B viruses. Three field isolates clustered closely with a 2002 Israel isolate, indicating a potential transmission route between these two countries and through the Middle East. The remaining five field isolates were closely related to a vaccine strain, even though broiler flocks in Turkey are not routinely vaccinated against aMPV. Therefore, we speculate these five isolates could have originated from nearby vaccinated turkey farms. Additionally, the presence of some nucleotide substitutions compared to the reference vaccine sequence suggests prolonged circulation and evolution of the original vaccine virus or a vaccine subpopulation was selected under field conditions. This evidence emphasizes the need for further detailed and more systemic approaches to evaluate aMPV spread and evolution in order to design effective control strategies.

Abstract
PURPOSE In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

Abstract
Risk assessment of central nervous system (CNS) infection patients is of key importance in predicting likely pathogens. However, data are lacking on the epidemiology globally. We performed a multicenter study to understand the burden of community-acquired CNS (CA-CNS) infections between 2012 and 2014. A total of 2583 patients with CA-CNS infections were included from 37 referral centers in 20 countries. Of these, 477 (18.5%) patients survived with sequelae and 227 (8.8%) died, and 1879 (72.7%) patients were discharged with complete cure. The most frequent infecting pathogens in this study were Streptococcus pneumoniae (n = 206, 8%) and Mycobacterium tuberculosis (n = 152, 5.9%). Varicella zoster virus and Listeria were other common pathogens in the elderly. Although staphylococci and Listeria resulted in frequent infections in immunocompromised patients, cryptococci were leading pathogens in human immunodeficiency virus (HIV)-positive individuals. Among the patients with any proven etiology, 96 (8.9%) patients presented with clinical features of a chronic CNS disease. Neurosyphilis, neurobrucellosis, neuroborreliosis, and CNS tuberculosis had a predilection to present chronic courses. Listeria monocytogenes, Staphylococcus aureus, M. tuberculosis, and S. pneumoniae were the most fatal forms, while sequelae were significantly higher for herpes simplex virus type 1 (p < 0.05 for all). Tackling the high burden of CNS infections globally can only be achieved with effective pneumococcal immunization and strategies to eliminate tuberculosis, and more must be done to improve diagnostic capacity.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. CONCLUSIONS Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically.

Abstract
Introduction. Spasticity is a major problem for the rehabilitation team. Physiotherapy is a vital component of therapy. Oral medication and other modalities such as heat, cold, ultrasound, electrical stimulation, and surgery (neuro-surgical or orthopedic) can also be used. The aim of this study was to compare the effects of hydrotherapy on spasticity and Functional Independence Measure (FIM) scores of patients with spinal cord injury (SCI). Materials and Methods. This is a control case matched study. Twenty SCI patients were divided into 2 groups and matched for age, gender, injury time, Ashworth scores, oral baclofen intake, American Spinal Injury Association, and FIM scores. The control group received passive range of motion exercise twice a day and oral baclofen for 10 weeks. The study group also received passive range of motion and oral baclofen, as well as 20 min of water exercises (at 71 °F, full immersion) 3 times per week. The authors evaluated spasm severity, FIM scores, oral baclofen intake, and Ashworth scales, between groups at the beginning and at the end of the treatment period. Results. Both groups demonstrated a significant increase in FIM scores. However, the hydrotherapy group demonstrated a larger increase (P < 0.0001) than the control group. There was a statistically significant decrease in oral baclofen intake in the hydrotherapy group (P < 0.01). There was no statistical change in the control group. Spasticity was evaluated by the Ashworth scale. There was a statistical improvement in each group (P < 0.01, P < 0.02). However, when compared to the control group, the use of hydrotherapy produced a significant decrease in spasm severity (P < 0.02). Conclusion. Side effects are often seen when using oral drug treatment for spasticity. Adding hydrotherapy to the rehabilitation program can be helpful in decreasing the amount of medication required. Future studies must evaluate benefits of hydrotherapy for rehabilitation.

Abstract
BACKGROUND AND PURPOSE Intracranial stents have become extremely important in the endovascular management of complex intracranial aneurysms. Sizing and landing zone predictions are still very challenging steps in the procedure. Virtual stent deployment may help therapeutic planning, device choice, and hemodynamic simulations. We aimed to assess the predictability of our recently developed virtual deployment model by comparing in vivo and virtual stents implanted in a consecutive series of patients presenting with intracranial aneurysms. MATERIALS AND METHODS Virtual stents were implanted in patient-specific geometries of intracranial aneurysms treated with the Pipeline Embolization Device. The length and cross-section of virtual and real stents measured with conebeam CT were compared. The influence of vessel geometry modifications occurring during the intervention was analyzed. RESULTS The virtual deployment based on pre- and poststent implantation 3D rotational angiography overestimated (underestimated) the device length by 13% ± 11% (-9% ± 5%). These differences were highly correlated (R2 = 0.67) with the virtual-versus-real stent radius differences of -6% ± 7% (5% ± 4%) for predictions based on pre- and poststent implantation 3D rotational angiography. These mismatches were due principally to implantation concerns and vessel-shape modifications. CONCLUSIONS The recently proposed geometric model was shown to predict accurately the deployment of Pipeline Embolization Devices when the stent radius was well-assessed. However, unpredictable delivery manipulations and variations of vessel geometry occurring during the intervention might impact the stent implantation.

Abstract
Background Postoperative atrial fibrillation is common after cardiac surgery. In this study, we aimed to investigate the value of interatrial conduction time for the prediction of early postoperative atrial fibrillation, using intra-operative transoesophageal echocardiography. Methods A total of 65 patients undergoing cardiac surgery in our hospital between January and March 2007 were prospectively evaluated, and 59 patients with sinus rhythm were included in the study. We performed transoesophageal echocardiography on all patients, and intra-operatively measured the interatrial conduction time, as recently described. The patients with episodes of atrial fibrillation during the post-surgery hospitalisation period were defined as group 1 and those without episodes were defined as group 2. Results Mean interatrial conduction time was 74 ± 15.9 ms in group 1 and 54 ± 7.9 ms in group 2. The difference in interatrial conduction time between the two groups was statistically significant (p < 0.05). In this study we found a statistically significant interatrial conduction delay between the groups. Postoperative atrial fibrillation was more frequent in patients with a longer interatrial conduction time. Conclusion Increased interatrial conduction time may cause postoperative atrial fibrillation and it can be measured intraoperatively by transoesophageal echocardiography.

Abstract
There have been many studies pertaining to the management of herpetic meningoencephalitis (HME), but the majority of them have focussed on virologically unconfirmed cases or included only small sample sizes. We have conducted a multicentre study aimed at providing management strategies for HME. Overall, 501 adult patients with PCR-proven HME were included retrospectively from 35 referral centres in 10 countries; 496 patients were found to be eligible for the analysis. Cerebrospinal fluid (CSF) analysis using a PCR assay yielded herpes simplex virus (HSV)-1 DNA in 351 patients (70.8%), HSV-2 DNA in 83 patients (16.7%) and undefined HSV DNA type in 62 patients (12.5%). A total of 379 patients (76.4%) had at least one of the specified characteristics of encephalitis, and we placed these patients into the encephalitis presentation group. The remaining 117 patients (23.6%) had none of these findings, and these patients were placed in the nonencephalitis presentation group. Abnormalities suggestive of encephalitis were detected in magnetic resonance imaging (MRI) in 83.9% of the patients and in electroencephalography (EEG) in 91.0% of patients in the encephalitis presentation group. In the nonencephalitis presentation group, MRI and EEG data were suggestive of encephalitis in 33.3 and 61.9% of patients, respectively. However, the concomitant use of MRI and EEG indicated encephalitis in 96.3 and 87.5% of the cases with and without encephalitic clinical presentation, respectively. Considering the subtle nature of HME, CSF HSV PCR, EEG and MRI data should be collected for all patients with a central nervous system infection.

Abstract
CONTEXT The World Health Organization has stated that psychiatric patients are a group of people who have oral and dental illnesses. AIMS The aims of this study were to document the oral hygiene of individuals with chronic psychiatric illness, to determine the extraoral and intraoral findings, to detect the dominant microorganisms in oral flora, and to inform clinicians of these findings. SETTINGS AND DESIGN The study included 100 patients (69 men and 31 women) with different psychiatric illnesses living in a nursing home. They were 19-96 years old (median, 48 years). SUBJECTS AND METHODS The participants completed a questionnaire about patients' oral health. They underwent extraoral and intraoral examinations. Two swab samples were obtained from the oral mucosa of these patients. Gram preparations were analyzed for leukocytes, bacteria, and yeast. STATISTICAL ANALYSIS USED Chi-square test and z-test were used. RESULTS All patients (100%) had the necessary equipment for oral hygiene; however, many (43%) patients had poor oral hygiene. There was a high prevalence of xerostomia (56%) and fissured tongue (61.4%) (among other tongue anomalies). The most commonly isolated microorganisms were coagulase-negative Staphylococcus0 (35.9%), Streptococcus spp. (30.3%), nondiphtheroid Bacilli (16.9%), Staphylococcus aureus (2.3%), Candida spp. (11.8%), and Gram-negative Bacilli (2.8%). CONCLUSIONS The oral hygiene of most patients was insufficient. The presence of Gram-negative Bacilli growth in the oral flora can be explained by poor hand hygiene. These findings suggest that it is useful to educate individuals about oral hygiene and hand hygiene and to inform the staff and families about this issue.

Abstract
BACKGROUND There is growing consensus in the literature that inflammation plays a central role in the pathophysiology of obesity and type 2 diabetes mellitus (T2DM) and cardiovascular complications. Neutrophil-to-lymphocyte ratio (NLR) provides a simple method for assessment of inflammatory status and it is a new, inexpensive marker. The aim of the present study was to investigate the predictive value of preprocedural (before the OGTT) NLR on development of type 2 diabetes (T2DM) in morbid obesity patients (MOP). METHODS 306 MOP (body mass index ≥ 40 kg/m(2)) and 95 normal weight patients with normal OGTT [fasting plasma glucose (FPG)<100mg/dL. Two-hour glucose during OGTT<140 mg/dL] were evaluated in this study. RESULTS The mean ± SD NLR of MOP was significantly higher than that of patients with normal weight healthy patients (3.67 ± 0.95 vs. 1.82 ± 1.02, P<0.001, respectively). In receiver operating characteristics curve analysis, NLR>3.12 had 79.2% sensitivity and 64.9% specificity in predicting T2DM. Logistic regression analysis showed that elevated NLR (OR: 2.577, 95% CI: 1.363-4.872, P=0.004) was an independent variable for predicting T2DM in MOP. CONCLUSIONS MOP have higher NLR than healthy controls. High NLR is a powerful and independent predictor of T2DM in MOP. Elevated NLR levels are usually considered as an inflammatory marker. The results of this study suggested that inflammation plays a role in the pathogenesis of T2DM with MOP.

Abstract
We aimed to describe clinical, laboratory, diagnostic and therapeutic features of spinal tuberculosis (ST), also known as Pott disease. A total of 314 patients with ST from 35 centres in Turkey, Egypt, Albania and Greece were included. Median duration from initial symptoms to the time of diagnosis was 78 days. The most common complications presented before diagnosis were abscesses (69%), neurologic deficits (40%), spinal instability (21%) and spinal deformity (16%). Lumbar (56%), thoracic (49%) and thoracolumbar (13%) vertebrae were the most commonly involved sites of infection. Although 51% of the patients had multiple levels of vertebral involvement, 8% had noncontiguous involvement of multiple vertebral bodies. The causative agent was identified in 41% of cases. Histopathologic examination was performed in 200 patients (64%), and 74% were consistent with tuberculosis. Medical treatment alone was implemented in 103 patients (33%), while 211 patients (67%) underwent diagnostic and/or therapeutic surgical intervention. Ten percent of the patients required more than one surgical intervention. Mortality occurred in 7 patients (2%), and 77 (25%) developed sequelae. The distribution of the posttreatment sequelae were as follows: 11% kyphosis, 6% Gibbus deformity, 5% scoliosis, 5% paraparesis, 5% paraplegia and 4% loss of sensation. Older age, presence of neurologic deficit and spinal deformity were predictors of unfavourable outcome. ST results in significant morbidity as a result of its insidious course and delayed diagnosis because of diagnostic and therapeutic challenges. ST should be considered in the differential diagnosis of patients with vertebral osteomyelitis, especially in tuberculosis-endemic regions. Early establishment of definitive aetiologic diagnosis and appropriate treatment are of paramount importance to prevent development of sequelae.

Abstract
OBJECTIVE A determinant of platelet function - mean platelet volume (MPV), is newly emerging risk factor for atherothrombosis. The aim of this study is to evaluate MPV in patients with primary hyperparathyroidism (PHPT) before parathyroidectomy (PTX) and six months after successful PTX in a retrospective study. METHODS We analyzed the changes in serum biochemical, parathyroid hormone (PTH) and MPV before and six months after PTX in 66 patients with PHPT and 44 healthy controls, age- and sex-matched. RESULTS Sixty-six patients (18 men, 48 women) with mean age 53.8 ± 12.7 years were analyzed. MPV was significantly higher in the patients with PHPT before PTX than in the same group after PTX (9.26 ± 1.20 fl vs. 7.99 ± 0.80 fl, p<0.0001). MPV levels were positively correlated with PTH (r=0.888, p<0.0001), calcium (r=0.292, p=0.017) in the preoperative phase. Postoperative (after 6 months) MPV showed a significant positive correlation with postoperative PTH (r=0.381, p=0.002) and calcium levels (r=0.324, p=0.008). CONCLUSIONS These results suggest that subjects with PHPT lead to have increased platelet activation.

Abstract
PURPOSE Galectin-3 (Gal-3) is a marker of cardiac fibrosis and predicts incident heart failure. Gal-3-deficient mice are resistant to multiple low-dose streptozotocin-induced diabetes. Recent experimental studies suggested an important role for Gal-3 in the regulation of adiposity, metaflammation and type 2 diabetes. This study aimed to examine the relationship between Gal-3 and newly diagnosed prediabetes and diabetes. METHODS Gal-3 concentrations were measured in 118 participants and 56 age- and sex-matched healthy controls. All subjects underwent a 75-g oral glucose tolerance test and were stratified into normal, prediabetic, and diabetes mellitus subgroups. DM was defined as a plasma glucose level ≥126 mg/dL in the fasting state or ≥200 mg/dL in the second hour after glucose loading. Impaired fasting glucose was defined as an FPG level of 100-125 mg/dL, and impaired glucose tolerance was defined as a 2-h plasma glucose level of 140-199 mg/dL. RESULTS Sixty-one patients had prediabetes (Group 1), 57 had diabetes (Group 2), and 56 had neither diabetes nor prediabetes (Group 3). Gal-3 levels correlated with FPG (r = 0.787, P < 0.01), 2hPG (r = 0.833, P < 0.01), CRP (r = 0.501, P < 0.01), and HOMA-IR (r = 0.518, P < 0.01). Gal-3 levels were higher in Group 2 than in Groups 1 and 3 [1,053.9 (358.1) and 744.1 (119.3) vs. 481.7 (175.4) pg/mL; P < 0.001]. Gal-3 is an independent predictor of diabetes in multivariate logistic analysis. In ROC analysis, a Gal-3 cutoff value of 803.55 pg/mL diagnoses diabetes with a sensitivity of 80.7 % and a specificity of 85.5 % (AUC = 0.912). CONCLUSIONS Gal-3 is a promising biomarker for detecting prediabetes and diabetes.

Abstract
OBJECTIVE Subclinical hypothyroidism and vitamin D deficiency are common. The diastolic function of patients with both subclinical hypothyroidism and vitamin D deficiency remains unknown. This study aimed to investigate diastolic dysfunction in patients with both subclinical hypothyroidism and vitamin D deficiency. SUBJECTS AND METHODS This study included 254 patients. All patients underwent standard Doppler echocardiography. Patients who had risk factors for diastolic dysfunction or had used L-thyroxine and vitamin D within the previous 3 months were excluded. Vitamin D deficiency was defined as a 25-OH-vitamin D level lower than 20 ng/ml, and vitamin D sufficiency was defined as a 25-OH-vitamin D level ≥ 30 ng/ml. Subclinical hypothyroidism was defined as a TSH level of 4.5-10 mU/l when the free T4 concentration was normal. RESULTS The patients were divided into 4 groups. Group 1 (n=71) included patients with subclinical hypothyroidism and vitamin D deficiency; Group 2 (n=66) included patients with subclinical hypothyroidism and vitamin D sufficiency; Group 3 (n=65) included euthyroid patients with vitamin D deficiency; and Group 4 (n=52) included euthyroid patients with vitamin D sufficiency. LAVI (31.3 ± 3.2, 28.7 ± 3.0, 28.4 ± 3.4, and 27.9 ± 3.9; p<0.001) and E/E' values (11.2 ± 2.7, 8.9 ± 2.7, 9.1 ± 2.9, 8.8 ± 2.5; p<0.001) were significantly higher in Group 1 than in Groups 2, 3 and 4. E' values were significantly lower in Group 1 than in Groups 2, 3 and 4. CONCLUSION The coexistence of subclinical hypothyroidism with vitamin D deficiency can lead to further deterioration in the LV diastolic function via the regulation of intracellular calcium and induction of inflammatory activity. Therefore, close follow-up of the diastolic functions of these patients could be beneficial.

Abstract
The presence of antibodies to feline coronavirus (FCoV) and feline immunodeficiency virus (FIV), together with feline leukemia virus (FeLV) antigen was investigated in 169 ill household and stray cats attending a veterinary surgery in Istanbul in 2009-14. The estimated FCoV and FIV seroprevalence (95% confidence intervals) were 37% (30-45%) and 11% (6-16%), respectively and FeLV prevalence was 1% (0-3%). FCoV seroprevalence increased until 2 years of age, was highest in 2014 and among household cats living with other cats and with outdoor access, and was lower in FIV seropositive compared to seronegative cats. Symptoms typically associated with wet feline infectious peritonitis (FIP) including ascites, abdominal distention or pleural effusion, coupled in many cases with non-antibiotic responsive fever, were observed in 19% (32/169) of cats, and 75% (24/32) of these cats were FCoV seropositive. FCoV seropositivity was also associated with a high white blood cell count, high plasma globulin, low plasma albumin and low blood urea nitrogen. The percentage of FCoV seropositive and seronegative cats that died in spite of supportive veterinary treatment was 33% (21/63) and 12% (13/106), respectively. These results indicate that FCoV is widespread and has a severe clinical impact in cats from Istanbul. Moreover, the incidence of FCoV infections could be rising, and in the absence of effective vaccination cat owners need to be made aware of ways to minimize the spread of this virus.

Abstract
BACKGROUND To evaluate colposcopic biopsy results of patients with cervical cytological findings of atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells with high-grade lesions that cannot be excluded (ASC-H). MATERIALS AND METHODS A retrospective evaluation of data from 358 patients, who had cervical cytological findings of ASC-US (n = 335) and ASC-H (n = 23), and had colposcopic assessments between 2005 and 2011. RESULTS Cervical biopsy results of patients diagnosed with ASC-US cytology (n = 335) revealed cervical squamous cell carcinoma 0.9 % (n = 3) at biopsy, cervical intraepithelial neoplasia 3 (CIN 3) in 3.8 % (n = 13), cervical intraepithelial neoplasia 2 (CIN 2) in 1.1 % (n = 4), cervical intraepithelial neoplasia 1 (CIN 1) in 35.2% (n = 118), and benign lesions in 59 % (n = 197). Cervical biopsy results of patients diagnosed with ASC-H cytology (n = 23) revealed CIN 3 at biopsy in 39.3% (n = 9), CIN 2 in 21.7% (n = 5), CIN 1 in 26% (n = 6), carcinoma in situ in 8.7% (n = 2), and squamous cell cancer in one patient (4.3%). CONCLUSION The cytological diagnosis of ASC-US may lead to the diagnosis of cervical intraepithelial lesion of higher grades as well as cervical cancer and should be evaluated by colposcopic cervical biopsy.

Abstract
BACKGROUND AND STUDY AIMS Bezoars result from accumulation of indigestible materials in the gastrointestinal tract and often occur in the stomach. In this study, we evaluated the use of guidewires in patients with gastric phytobezoars (PBs) as a new method for PB removal and examined the safety of the procedure. PATIENTS AND METHODS Between February 2009 and January 2013, we analyzed data from 11 patients with gastric PBs. We fitted a transparent cap to a standard endoscope (EG450WR5, Fujinon), and a 0.025 inch guidewire was passed through the standart endoscope. PBs were surrounded by a loop in the guidewire and destroyed. After 2 weeks of treatment, patients were re-evaluated for effectiveness. RESULTS PB fragmentation time was 5-11 minutes. In five patients with a history of gastric surgery, we needed an additional 16-28 minutes for removal of the fragments. In six patients additionally treated with enzymatic degradation after the breaking procedure, PBs completely disappeared within 2 weeks. There were no complications during the procedure. CONCLUSIONS The guidewire and fragmentation procedure for PBs is an efficient and reliable method. When combined with enzymatic degradation, PBs can be managed quickly and effectively.

Abstract
BACKGROUND/AIMS Increased carotid intima-media thickness (CIMT) was shown to be an independent predictor of cardiovascular (CV) mortality in dialysis patients and the general population. Growth differentiation factor 15 (GDF-15), a member of the transforming growth factor superfamily, is produced by cardiomyocytes and atherosclerotic lesions under stress conditions such as inflammation. We assessed associations between serum concentrations of GDF-15, mortality, and CIMT for subclinical atherosclerosis in hemodialysis (HD) patients. METHODS A total of 87 patients on maintenance hemodialysis and 45 sex- and age-matched healthy controls were included in this prospective study. Serum GDF-15 levels were measured by ELISA. CIMT was assessed by Doppler ultrasonography. The association between serum GDF-15 levels and mortality was assessed using Cox regression analysis with serum levels categorized into two groups according to the median value (328.18 pg/ml). Patients were followed for 2 years and cause-specific and all-cause mortality were determined. RESULTS The median level of serum GDF-15 was significantly higher in HD patients than controls [328 (198-522) vs. 176 (101-289) pg/ml, p < 0.01, respectively]. Serum GDF-15 levels were correlated to CIMT (r = 0.607, p < 0.001), C-reactive protein (CRP; r = 0.250, p = 0.010), HD duration (r = 0.376, p = 0.004), and serum albumin (r = - 0.156, p = 0.030). The multivariate analysis revealed that GDF-15 was found to be an independent variable of CIMT in HD patients. In the study, the serum GDF-15 level was an independent marker of all-cause of mortality when adjusted for age, CRP, and history of diabetes mellitus. CONCLUSION The relationship between serum GDF-15, mortality, and carotid artery thickening suggests that GDF-15 may be a novel marker of atherosclerosis, inflammation, and malnutrition in HD patients.

Abstract
In this multicentre study, which is the largest case series ever reported, we aimed to describe the features of tularaemia to provide detailed information. We retrospectively included 1034 patients from 41 medical centres. Before the definite diagnosis of tularaemia, tonsillitis (n = 653, 63%) and/or pharyngitis (n = 146, 14%) were the most frequent preliminary diagnoses. The most frequent clinical presentations were oropharyngeal (n = 832, 85.3%), glandular (n = 136, 13.1%) and oculoglandular (n = 105, 10.1%) forms. In 987 patients (95.5%), the lymph nodes were reported to be enlarged, most frequently at the cervical chain jugular (n = 599, 58%), submandibular (n = 401, 39%), and periauricular (n = 55, 5%). Ultrasound imaging showed hyperechoic and hypoechoic patterns (59% and 25%, respectively). Granulomatous inflammation was the most frequent histological finding (56%). The patients were previously given antibiotics for 1176 episodes, mostly with β-lactam/β-lactamase inhibitors (n = 793, 76%). Antituberculosis medications were provided in seven (2%) cases. The patients were given rational antibiotics for tularaemia after the start of symptoms, with a mean of 26.8 ± 37.5 days. Treatment failure was considered to have occurred in 495 patients (48%). The most frequent reasons for failure were the production of suppuration in the lymph nodes after the start of treatment (n = 426, 86.1%), the formation of new lymphadenomegalies under treatment (n = 146, 29.5%), and persisting complaints despite 2 weeks of treatment (n = 77, 15.6%). Fine-needle aspiration was performed in 521 patients (50%) as the most frequent drainage method. In conclusion, tularaemia is a long-lasting but curable disease in this part of the world. However, the treatment strategy still needs optimization.

Abstract
OBJECTIVE Recent studies revealed that inflammation plays a critical role in bone remodeling and the pathogenesis of postmenopausal osteoporosis, a major health concern. Neutrophil-lymphocyte ratio (NLR) is a cost-effective marker of inflammation that has been linked with several diseases. This study aimed to compare NLR and C-reactive protein (CRP) levels in osteopenic, osteoporotic, and control subjects and to assess the correlation between NLR levels, CRP, and bone mineral density (BMD) in postmenopausal women. METHODS In this cross-sectional study, the relationship between NLR, CRP, and BMD in 438 women was investigated using uni- and multivariate analyses. BMD (g/cm²) was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine and femur. Complete blood count (CBC), CRP, glucose/lipid metabolism, and established risk factors were determined. RESULTS In the osteoporotic group, NLR and CRP levels were found to be elevated as compared to the osteopenic and control groups (NLR: 4.68 ± 0.72, 3.17 ± 0.43, 2.01 ± 0.54; CRP: 12.3 ± 4.1, 4.1 ± 2.7, 3.2 ± 2.1, respectively). A negative correlation was present between NLR and the lumbar spine (L2-L4) and femoral neck BMD after adjusting other risk factors. There was no correlation between CRP levels and BMD after adjusting other risk factors. NLR was significantly associated with L2-L4 BMD (ß = -0.653, p<0.001) and femoral neck BMD (ß = -0.178, p<0.001), but CRP level had no association with BMD in a multivariate model. CONCLUSIONS Our data indicate that NLR may be a better predictor than CRP for occurrence of osteoporosis in postmenopausal women.

Abstract
AIM AND BACKGROUND Galectin-3 (Gal-3) is used to determine the prognosis of heart failure. Some studies revealed that Gal-3 promoted cardiac hypertrophy but there is no study in which the relationship between Gal-3 and left ventricular hypertrophy (LVH) geometry in patients without diastolic and systolic function impairment has been explored. The aim of the study was to analyze associations between plasma Gal-3 levels, LVH, and LV geometry in maintenance hemodialysis (HD) patients without systolic and diastolic dysfunction. PATIENTS AND METHODS The study group included 105 patients (53 women and 52 men)--with an average age of 58.2 ± 12.6 years, treated with HD for an average of 45 ± 32 months--and 60 healthy controls. The Gal-3 and other biochemical parameters were measured and color Doppler echocardiography was performed. For this study LVH was considered present when the LV mass index (LVMI) exceeded 95 g/m(2) in women and 115 g/m(2) in men. Left ventricular geometry was classified into the four groups on the basis of left ventricular mass and relative wall thickness (RWT). RESULTS Concentric hypertrophy (CH, 40.9 %, n = 43) was the commonest geometric pattern in our study. The Gal-3 levels in CH patients were not different from the patients with eccentric hypertrophy (EH). Plasma levels of Gal-3 correlated with LVMI (r = 0.617, p < 0.001), parathyroid hormone (PTH, r = 0.408, p < 0.001), uric acid (r = 0.281, p = 0.004), C-reactive protein (CRP, r = 0.412, p < 0.001), and RWT (r = 0.281, p = 0.004) but were inversely correlated with albumin (r = - 0.466, P < 0.001) in the whole group. Plasma levels of Gal-3 were associated with LVMI (r = 0.812, P < 0.001), RWT (r = 0.318, p = 0.001), and CRP(r = 0.381, p < 0.001) in maintenance hemodialysis patients. CONCLUSION The Gal-3 level is related to left ventricular hypertrophy and it is independent of left ventricle geometry. The relationship between LVH and Gal-3 might be direct or it may also be inflammation-related.

Abstract
The aim of this study was to assess the infectious diseases (ID) wards of tertiary hospitals in France and Turkey for technical capacity, infection control, characteristics of patients, infections, infecting organisms, and therapeutic approaches. This cross-sectional study was carried out on a single day on one of the weekdays of June 17-21, 2013. Overall, 36 ID departments from Turkey (n = 21) and France (n = 15) were involved. On the study day, 273 patients were hospitalized in Turkish and 324 patients were followed in French ID departments. The numbers of patients and beds in the hospitals, and presence of an intensive care unit (ICU) room in the ID ward was not different in both France and Turkey. Bed occupancy in the ID ward, single rooms, and negative pressure rooms were significantly higher in France. The presence of a laboratory inside the ID ward was more common in Turkish ID wards. The configuration of infection control committees, and their qualifications and surveillance types were quite similar in both countries. Although differences existed based on epidemiology, the distribution of infections were uniform on both sides. In Turkey, anti-Gram-positive agents, carbapenems, and tigecycline, and in France, cephalosporins, penicillins, aminoglycosides, and metronidazole were more frequently preferred. Enteric Gram-negatives and hepatitis B and C were more frequent in Turkey, while human immunodeficiency virus (HIV) and streptococci were more common in France (p < 0.05 for all significances). Various differences and similarities existed in France and Turkey in the ID wards. However, the current scene is that ID are managed with high standards in both countries.

Abstract
The purpose of this investigation was to compare the efficacy of colistin-based therapies in extremely drug-resistant Acinetobacter spp. bloodstream infections (XDR-ABSI). A retrospective study was conducted in 27 tertiary-care centers from January 2009 to August 2012. The primary end-point was 14-day survival, and the secondary end-points were clinical and microbiological outcomes. Thirty-six and 214 patients [102 (47.7%): colistin-carbapenem (CC), 69 (32.2%): colistin-sulbactam (CS), and 43 (20.1%: tigecycline): colistin with other agent (CO)] received colistin monotherapy and colistin-based combinations, respectively. Rates of complete response/cure and 14-day survival were relatively higher, and microbiological eradication was significantly higher in the combination group. Also, the in-hospital mortality rate was significantly lower in the combination group. No significant difference was found in the clinical (p = 0.97) and microbiological (p = 0.92) outcomes and 14-day survival rates (p = 0.79) between the three combination groups. Neither the timing of initial effective treatment nor the presence of any concomitant infection was significant between the three groups (p > 0.05) and also for 14-day survival (p > 0.05). Higher Pitt bacteremia score (PBS), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Charlson comorbidity index (CCI), and prolonged hospital and intensive care unit (ICU) stay before XDR-ABSI were significant risk factors for 14-day mortality (p = 0.02, p = 0.0001, p = 0.0001, p = 0.02, and p = 0.01, respectively). In the multivariable analysis, PBS, age, and duration of ICU stay were independent risk factors for 14-day mortality (p < 0.0001, p < 0.0001, and p = 0.001, respectively). Colistin-based combination therapy resulted in significantly higher microbiological eradication rates, relatively higher cure and 14-day survival rates, and lower in-hospital mortality compared to colistin monotherapy. CC, CS, and CO combinations for XDR-ABSI did not reveal significant differences with respect to 14-day survival and clinical or microbiological outcome before and after propensity score matching (PSM). PBS, age, and length of ICU stay were independent risk factors for 14-day mortality.
