    Impact of echocardiography on one-month and one-year mortality of intertrochanteric fracture patients
    (2018) Kalem, Mahmut; Tıp Fakültesi; Kocaoğlu, Hakan; Başarır , Kerem
    Objective: The aim of this study was to analyze the effects of preoperative echocardiography on patient survival, timing of surgery in length of hospital stay in patients who will undergo hip nailing for an intertrochanteric fracture. Methods: The clinical records of the patients who were admitted to a tertiary university hospital with an intertrochanteric femur fracture were retrospectively analyzed. The age, gender, American Society of Anesthesiologists (ASA) score, days to surgery, total hospital stay, cardiac drug prescription/modification, cardiac intervention and presence of an echocardiography assessment including detailed findings were reviewed. Mortality data were accessed from the national civil registration system. Results: 181 (110 women and 71 men; mean age 81 (44-98)) cases were studied whom 65 underwent pre-operative echocardiography. Time to surgery and total hospital stay was 2 days longer at transthoracic echocardiography (TTE) group (p < 0.001). At one month control group survival rate was 93.1% on contrary it was 75.4% at TTE group. One-year survival rates were 77.3% and 55.1% respectively. Likewise mean expected survival time was 21.6 ± 1.03 months for control group and 15.12 ± 1.64 months for TTE group (p < 0.001). Only increased left ventricular end diastolic diameter (LVEDD) was showed to be associated with increasing one-year mortality with a hazard ratio of 10.78 (2.572-45.19) at multivariate model. Conclusion: Cardiac findings and requisite for preoperative TTE and increased LVEDD is a strong predictor for mortality. TTE significantly lengthens the time to surgery. Also LVEDD measurement can be easily performed in the bedside which we believe would save time and reduce mortality. Level of evidence: Level III Diagnostic study.

    Analyzing differential item functioning of the Nottingham Health Profile by Mixed Rasch Model
    (2018) Elhan, Atilla Halil; Tıp Fakültesi
    Objectives: This study aims to evaluate whether items in the Turkish version of the Nottingham Health Profile (NHP) function differently according to age, sex, and duration of pain using the Mixed Rasch Model (MRM). Patients and methods: The NHP data of patients with low back pain from a previous study was analyzed. To analyze differential item functioning (DIF) within the items of the NHP, the MRM was used. Age, sex, and duration of pain were considered factors which could cause DIF. The most powerful factor to define latent classes derived from the MRM was estimated using the Rasch tree method. Results: The two-class mixture version of the nominal response model was identified as the best fitting model for the physical mobility, sleep, and social isolation sections. For the physical mobility dimension, some items showed DIF by age and for the social isolation dimension some items showed DIF by sex. For the sleep dimension, latent classes were unable to be explained by age, sex, and duration of pain. Items in other dimensions of the NHP were DIF-free and no items showed DIF according to age, sex, and duration of pain. Conclusion: The results of this study may shed light on explaining the different response behavior of patients on the items of the NHP. Age and sex were found to be variables affecting item responses of NHP. Contrary to expectations, duration of pain did not cause DIF for any item. From the perspective of DIF, it can be concluded that NHP scale is a robust scale in terms of validity.

    Temperature Effects Explain Continental Scale Distribution of Cyanobacterial Toxins
    (2018) Demir, Nilsun; Ziraat Fakültesi
    Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota. Generalized linear models showed that a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability. Increases in TDI were explained through a significant increase in toxin variants such as MC-YR, anatoxin and cylindrospermopsin, accompanied by a decreasing presence of MC-LR. While global warming continues, the direct and indirect effects of increased lake temperatures will drive changes in the distribution of cyanobacterial toxins in Europe, potentially promoting selection of a few highly toxic species or strains.

    Epidemiology of sepsis in intensive care units in Turkey: a multicenter, point-prevalence study
    (2018) Arslantaş, Mustafa Kemal; Tıp Fakültesi
    Background: The prevalence and mortality of sepsis are largely unknown in Turkey, a country with high antibiotic resistance. A national, multicenter, point-prevalence study was conducted to determine the prevalence, causative microorganisms, and outcome of sepsis in intensive care units (ICUs) in Turkey. Methods: A total of 132 ICUs from 94 hospitals participated. All patients (aged > 18 years) present at the participating ICUs or admitted for any duration within a 24-h period (08:00 on January 27, 2016 to 08:00 on January 28, 2016) were included. The presence of systemic inflammatory response syndrome (SIRS), severe sepsis, and septic shock were assessed and documented based on the consensus criteria of the American College of Chest Physicians and Society of Critical Care Medicine (SEPSIS-I) in infected patients. Patients with septic shock were also assessed using the SEPSIS-III definitions. Data regarding demographics, illness severity, comorbidities, microbiology, therapies, length of stay, and outcomes (dead/alive during 30 days) were recorded. Results: Of the 1499 patients included in the analysis, 237 (15.8%) had infection without SIRS, 163 (10.8%) had infection with SIRS, 260 (17.3%) had severe sepsis without shock, and 203 (13.5%) had septic shock. The mortality rates were higher in patients with severe sepsis (55.7%) and septic shock (70.4%) than those with infection alone (24.8%) and infection + SIRS (31.2%) (p < 0.001). According to SEPSIS-III, 104 (6.9%) patients had septic shock (mortality rate, 75.9%). The respiratory system (71.6%) was the most common site of infection, and Acinetobacter spp. (33.7%) were the most common isolated pathogen. Approximately, 74.9%, 39.1%, and 26.5% of Acinetobacter, Klebsiella, and Pseudomonas spp. isolates, respectively, were carbapenem-resistant, which was not associated with a higher mortality risk. Age, acute physiology and chronic health evaluation II score at ICU admission, sequential organ failure assessment score on study day, solid organ malignancy, presence of severe sepsis or shock, Candida spp. infection, renal replacement treatment, and a nurse-to-patient ratio of 1:4 (compared with a nurse-to-patient ratio of 1:2) were independent predictors of mortality in infected patients. Conclusions: A high prevalence of sepsis and an unacceptably high mortality rate were observed in Turkish ICUs. Although the prevalence of carbapenem resistance was high in Turkish ICUs, it was not associated with a higher risk for mortality. Trial registration: ClinicalTrials.gov ID NCT03249246 . Date: August 15, 2017. Retrospectively registered.

    Preoperative right heart hemodynamics predict postoperative acute kidney injury after heart transplantation
    (2018) Guven, Goksel; Tıp Fakültesi
    Purpose: Acute kidney injury (AKI) frequently occurs after heart transplantation (HTx), but its relation to preoperative right heart hemodynamic (RHH) parameters remains unknown. Therefore, we aimed to determine their predictive properties for postoperative AKI severity within 30 days after HTx. Methods: From 1984 to 2016, all consecutive HTx recipients (n = 595) in our tertiary referral center were included and analyzed for the occurrence of postoperative AKI staged by the kidney disease improving global outcome criteria. The effects of preoperative RHH parameters on postoperative AKI were calculated using logistic regression, and predictive accuracy was assessed using integrated discrimination improvement (IDI), net reclassification improvement (NRI), and area under the receiver operating characteristic curves (AUC). Results: Postoperative AKI occurred in 430 (72%) patients including 278 (47%) stage 1, 66 (11%) stage 2, and 86 (14%) stage 3 cases. Renal replacement therapy (RRT) was administered in 41 (7%) patients. Patients with higher AKI stages had also higher baseline right atrial pressure (RAP; median 7, 7, 8, and in RRT 11 mmHg, p trend = 0.021), RAP-to-pulmonary capillary wedge pressure ratio (median 0.37, 0.36, 0.40, 0.47, p trend = 0.009), and lower pulmonary artery pulsatility index (PAPi) values (median 2.83, 3.17, 2.54, 2.31, p trend = 0.012). Higher RAP and lower PAPi values independently predicted AKI severity [adjusted odds ratio (OR) per doubling of RAP 1.16 (1.02-1.32), p = 0.029; of PAPi 0.85 (0.75-0.96), p = 0.008]. Based on IDI, NRI, and delta AUC, inclusion of these parameters improved the models' predictive accuracy. Conclusions: Preoperative PAPi and RAP strongly predict the development of AKI early after HTx and can be used as early AKI predictors.

    Evaluation of the lifespan extension effects of several Turkish medicinal plants in Caenorhabditis elegans
    (2018) Ergen, Nuri; Biyoteknoloji Enstitüsü
    Research on longevity is important to both prolong lifespan and support healthy aging. Natural products are widely being utilized and used as new resources for drug molecules. Caenorhabditis elegans is an advantageous organism for longevity research and age-related diseases. In this study, we tested a number of plant extracts for their effects on C. elegans longevity. In lifespan assays, agesynchronized wild-type C. elegans specimens were treated with different concentrations of plant extracts. Plant extracts were prepared as either infusions or decoctions, similar to their traditional utilization. Hedera helix L. (Araliaceae) extended lifespan in worms in a concentration-dependent manner. The mean survival rates in the H. helix-treated groups were significantly higher, by 23.7% when applied at 1000 µg/mL, 16% when applied at 500 µg/mL, and 16% when applied at 250 µg/mL, compared to the control group. HPLC analysis identified chlorogenic acid as the major component of H. helix. Salvia verticillata L. (Lamiaceae) and Myrtus communis L. (Myrtaceae) treatments resulted in median lifespan extension. Maximum lifespan was extended in worms by Rubus sanctus Schreb. (Rosaceae) treatment. This study provided the first evidence demonstrating the possible lifespan-extending effects of a group of Turkish medicinal plants in an in vivo model, C. elegans.

    Tricuspid valve surgery in implantable cardiac electronic device-related endocarditis: Repair or replace?
    (2018) Çakıcı, Mehmet; Tıp Fakültesi
    Background: The aim of this study was to investigate lead endocarditis-related tricuspid valve regurgitation, to identify underlying causes, and to report our surgical approaches to tricuspid valve endocarditis. Methods: Between March 2010 and August 2016, medical records of a total of 43 patients (23 males, 20 females; mean age: 63.2±13.6 years; range 48 to 72 years) who underwent tricuspid valve surgery for severe tricuspid regurgitation caused by lead endocarditis, which was previously placed as an implantable cardiac electronic device were reviewed. We removed all systems including infected leads and generators, revised infected wounds and tissues, performed tricuspid valve surgery for lead endocarditis, and applied long-term intravenous antibiotic regimen for the culprit agent, as confirmed by the culture. Results: Of 43 patients, 18 underwent tricuspid valve repair and 25 underwent tricuspid valve replacement for lead endocarditisrelated severe tricuspid valve regurgitation. During followup (range, 2 to 62 months), two patients required temporary mechanical support due to postoperative acute right heart failure, while eight patients died due to sepsis (n=6; 14%) and stroke (n=2; 4.6%) in the early postoperative period. The remaining patients showed significant improvement in signs and symptoms of heart failure. Conclusion: Our study results suggest that incompetent experience and inaccurate decision for valve repair may result in delayed valve replacement and prolonged operation time.

    Antimicrobial Resistance of Enterococcus Species Isolated from Chicken in Turkey
    (2018) Sanlibaba, Pınar; Mühendislik Fakültesi
    The aim of the present work was to provide information about Enterococcus strains isolated from pre-packaged chicken samples in Ankara (Turkey), focusing on their prevalence, phenotypic and genotypic characteristics, and antibiotic resistance. We report the first study on the occurrence of antibiotic resistant enterococci in pre-packaged chicken samples in Ankara. A total of 97 suspicious enterococcal isolates were identified from 122 chicken samples. All isolates were identified to species level by phenotypic and molecular methods. In the 16S rDNA sequence analysis, Enterococcus faecium (61.85%) and Enterococcus faecalis (38.15%) were found to be the most frequently detected Enterococcus spp. Of the 97 isolates tested for hemolytic activity, 12.37% enterococcal strains were β-hemolytic. β-Hemolysin was most prevalent among E. faecium (58.33%) compared to E. faecalis (41.66%). Disk diffusion method was used for determining of antibiotic resistance. The analysis of the antimicrobial resistance of the 97 Enterococcus isolates revealed that the resistance to kanamycin (98.96%), rifampicin (80.41%) and ampicillin (60.82%) was most frequent. Furthermore, resistance to erythromycin (38.14%) and ciprofloxacin (34.02%) was also observed. The frequencies of resistance to tetracycline (9.27%), penicillin G (8.24%), and chloramphenicol (3.09%), gentamicin (2.06%) and streptomycin (1.03%) were low. None of the isolates was resistant to vancomycin. Multi-drug resistance was found in 97.93% of Enterococcus strains. E. faecium strains showed a more resistant phenotype than E. faecalis strains according to the antibiotic resistance levels. The results of this study indicated that chicken meat is a potential reservoir for the transmission of antibiotic resistance from animals to humans.

    Diagnostic and Prognostic Role of Serum Interleukin-6 in Malignant Transformation of Liver Cirrhosis
    (2018) Özkan, Hasan; Tıp Fakültesi
    Aim: Alpha-fetoprotein (AFP) is still the most commonly used and the single most recommended marker in the diagnosis of hepatocellular carcinoma (HCC). Interleukin (IL)-6 is a circular cytokine and its role on carcinogenesis in various hematological and solid tumors is clearly documented. A combination of serum IL-6 and AFP may provide beneficial information regarding early diagnosis of HCC. In this study, the effect of plasma IL-6 level in the diagnosis of HCC was investigated. Materials and methods: A total of 130 patients with liver cirrhosis, together with 30 control cases were enrolled in the trial. A diagnosis of HCC was present in 75 patients (57.6%) in the liver cirrhosis group. Blood samples were obtained from the enrolled study and control cases. Alpha-fetoprotein was quantified by chemiluminescent method. Plasma IL-6 levels of samples obtained at -80°C were quantified by human IL-6 BMS213/2 BMS213/2TEN kit. Results: The HCC patients were older than the patients in the cirrhosis group (p = 0.016). On comparison of the HCC patients with the control group, AFP (p < 0.001) and IL-6 (p < 0.001) were significantly higher among the HCC patients. Comparison of HCC patients with liver cirrhosis cases with no diagnosis of HCC revealed significantly high AFP (p < 0.001) and IL-6 levels (p < 0.001) in HCC group. Cutoff value for IL-6 was calculated as 5.73 (pg/mL). No difference was detected in AFP (p = 0.600) and IL-6 (0.344) in all three subgroups. A total of 17 patients died during a mean follow-up period of 32.9 months. No correlation was found between mean AFP values and IL-6 values and survival rates. Conclusion: Plasma IL-6 level was found to be significant in the diagnosis of HCC. Alpha-fetoprotein and IL-6 provided no advantage in terms of early diagnosis of HCC and no correlation was observed between these markers and survival.How to cite this article: Yakut M, Özkan H, Karakaya MF, Erdal H.

    (2018) Özkan, Hasan; Tıp Fakültesi
    Hepatitis B virus (HBV) infection is a global public health problem and it is also a major health concern of Turkey. The estimated number of HBV carriers in Turkey is about 3.3 million, with an overall HBV prevalence of 4.57%. Thus, both prevention and therapy of HBV-infected patients are urgent medical need of Turkey. A total of 1,533 among 37,637 patients who were examined at the Department of Gastroenterology, Ankara University School of Medicine were found to be hepatitis B surface antigen (HBsAg) positive (4%). Viral hepatitis treatment is fully reimbursed in Turkey through the national insurance system, which covers all residents across Turkey. How to cite this article: Özkan H.

    Dairy Products Added in Media Affect the Development of Drosophila melanogaster (Diptera: Drosophilidae)
    (2018) Ozgumus Demir, Emel; Ziraat Fakültesi
    Due to the increased interest shown in kefir, the present study examined its effects on some developmental characteristics in Drosophila. To compare the results related to kefir, another fermented product, i.e., yogurt, and the raw material of kefir, i.e., milk, were included in the experiment. All three foods were fed to Drosophila by addition to the medium. The results showed that the three foods delayed development in generations F1 and F2. In both generations, the number of adults was lower than that of the control group, but the comparison of the foods among themselves showed no significant difference. Moreover, the negative effect continued in generation F2. Phenotypically abnormal individuals were observed in the experiments, but there was no significant difference. Furthermore, the sex ratio changed in all the groups, including the control group. In the experimental group fed kefir, the sex ratio changed in favor of females, whereas in the other groups, it changed in favor of males. Whether the milk and milk products were fermented did not change the effect on Drosophila, but unexpectedly it delayed development, reduced the number of adults, and changed the sex ratio. It can be concluded that the three foods delayed development and altered the sex ratio in Drosophila.

    Prevention and management of adverse events of novel agents in multiple myeloma: a consensus of the European Myeloma Network
    (2018) Beksac, Meral; Tıp Fakültesi
    During the last few years, several new drugs have been introduced for treatment of patients with multiple myeloma, which have significantly improved the treatment outcome. All of these novel substances differ at least in part in their mode of action from similar drugs of the same drug class, or are representatives of new drug classes, and as such present with very specific side effect profiles. In this review, we summarize these adverse events, provide information on their prevention, and give practical guidance for monitoring of patients and for management of adverse events.

    Prevalence of asthma among the adult general population of five Middle Eastern countries: results of the SNAPSHOT program
    (2018) Aydin, Ömür; Tıp Fakültesi
    Background: Asthma is a common chronic respiratory disease leading to morbidity, mortality and impaired quality of life worldwide. Information on asthma prevalence in the Middle East is fragmented and relatively out-dated. The SNAPSHOT program was conducted to obtain updated information. Methods: SNAPSHOT is a cross-sectional epidemiological program carried out in five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia, and the United Arab Emirates, the latter three grouped into a Gulf cluster) to collect data on asthma, allergic rhinitis, benign prostatic hyperplasia and bipolar disorder. The survey was carried out by telephone in a random sample of the adult general population with quotas defined according to country demographics. The analysis presented in this paper focuses on asthma. Subjects were screened for asthma based on criteria from the global Asthma Insights and Reality studies. Current prevalence (last 12 months) was estimated. Multivariate logistic regression analyses were used to investigate risk factors related to asthma and the association with allergic rhinitis and other co-morbidities. Quality of life was assessed using the three-level EQ-5D questionnaire. Results: 2124 out of the 33,486 subjects enrolled in the SNAPSHOT program fulfilled the criteria for asthma. The adjusted prevalence of asthma ranged from 4.4% [95% CI: 4.0-4.8%] in Turkey, to 6.7% [95% CI: 6.2-7.2%] in Egypt and 7.6% [95% CI: 7.1-8.0%] in the Gulf cluster. Prevalence was higher (p < 0.0001) in women than men and increased with age (p < 0.0001). Co-morbidities occurred more frequently in asthma subjects compared to the non-asthma population (38% vs. 15% p < 0.0001). Subjects with asthma reported a lower (p < 0.0001) EQ-VAS score (68.2 ± 22.9) compared to the general population (78.1 ± 17.5). The risk factors associated with asthma were age, gender, country, and certain co-morbidities, namely respiratory, cardiovascular, gastrointestinal, nervous, and neurological diseases. Conclusion: The observed adjusted prevalence of asthma in the Middle East ranges from 4.4% to 7.6%, which is comparatively lower than the reported prevalence in Europe and North America. Asthma has a negative impact on quality of life, and is associated with high levels of co-morbid diseases, indicating a need for physicians to check for co-morbidities and ensure they are managed correctly in all asthma patients.

    (2018) Ataman, Şebnem; Tıp Fakültesi
    Objectives: This study aims to establish the first national treatment recommendations by the Turkish League Against Rheumatism (TLAR) for psoriatic arthritis (PsA) based on the current evidence. Patients and methods: A systematic literature review was performed regarding the management of PsA. The TLAR expert committee consisted of 13 rheumatologists and 12 physical medicine and rehabilitation specialists experienced in the treatment and care of patients with PsA from 22 centers. The TLAR recommendations were built on those of European League Against Rheumatism (EULAR) 2015. Levels of evidence and agreement were determined. Results: Recommendations included five overarching principles and 13 recommendations covering therapies for PsA, particularly focusing on musculoskeletal involvement. Level of agreement was greater than eight for each item. Conclusion: This is the first paper that summarizes the recommendations of TLAR as regards the treatment of PsA. We believe that this paper provides Turkish physicians dealing with PsA patients a practical guide in their routine clinical practice.

    A direct tissue-grafting approach to increasing endogenous brown fat
    (2018) Karakecili, Ayse; Mühendislik Fakültesi
    There is widespread evidence that increasing functional mass of brown adipose tissue (BAT) via browning of white adipose tissue (WAT) could potentially counter obesity and diabetes. However, most current approaches focus on administration of pharmacological compounds which expose patients to highly undesirable side effects. Here, we describe a simple and direct tissue-grafting approach to increase BAT mass through ex vivo browning of subcutaneous WAT, followed by re-implantation into the host; this cell-therapy approach could potentially act synergistically with existing pharmacological approaches. With this process, entitled "exBAT", we identified conditions, in both mouse and human tissue, that convert whole fragments of WAT to BAT via a single step and without unwanted off-target pharmacological effects. We show that ex vivo, exBAT exhibited UCP1 immunostaining, lipid droplet formation, and mitochondrial metabolic activity consistent with native BAT. In mice, exBAT exhibited a highly durable phenotype for at least 8 weeks. Overall, these results enable a simple and scalable tissue-grafting strategy, rather than pharmacological approaches, for increasing endogenous BAT and studying its effect on host weight and metabolism

    The Effects of Bougie Diameters on Tissue Oxygen Levels After Sleeve Gastrectomy: A Randomized Experimental Trial
    (2018) Konca, Can; Tıp Fakültesi
    Background: Staple-line leak is the most frightening complication of laparoscopic sleeve gastrectomy and several predisposing factors such as using improper staple sizes regardless of gastric wall thickness, narrower bougie diameter and ischemia of the staple line are asserted. Aims: To evaluate the effects of different bougie diameters on tissue oxygen partial pressure at the esophagogastric junction after sleeve gastrectomy. Study design: A randomized and controlled animal experiment with 1:1:1:1 allocation ratio. Methods: Thirty-two male Wistar Albino rats were randomly divided into 4 groups of 8 each. While 12-Fr bougies were used in groups 1 and 3, 8-Fr bougies were used in groups 2 and 4. Fibrin sealant application was also carried out around the gastrectomy line after sleeve gastrectomy in groups 3 and 4. Burst pressure of gastrectomy line, tissue oxygen partial pressure and hydroxyproline levels at the esophagogastric junction were measured and compared among groups. Results: Mortality was detected in 2 out of 32 rats (6.25%) and one of them was in group 2 and the cause of this mortality was gastric leak. Gastric leak was detected in 2 out of 32 rats (6.25%). There was no significant difference in terms of burst pressures, tissue oxygen partial pressure and tissue hydroxyproline levels among the 4 groups. Conclusion: The use of narrower bougie along with fibrin sealant has not had a negative effect on tissue perfusion and wound healing.
