Article Citation - WoS: 1Citation - Scopus: 125-Hydroxyvitamin Levels in Sjögren’s Syndrome: Is It the Right Time to Dismiss the Case or Not(Walter de Gruyter GmbH, 2024) Sımsır, Ilgın Yıldırım; Tanigor, Goksel; Karabulut, Gonca; Barutcuoglu, Burcu; Yılmaz, ZevcetObjectives: This study aimed to investigate whether patients with primary Sjögren syndrome (SjS) have different levels of 25 OH-D3 (vitamin D) when compared to healthy populations and whether differences in 25 OH-D3 correlated with disease activity or markers. Methods: Eighty-eight female patients with SjS and 3,338 age-matched healthy female controls were included in this study. 25 OH-D3 levels were compared with healthy controls. Then the patients were stratified according to their 25 OH-D3 levels, either insufficient/deficient or normal (<50 nmol/L or ≥50 nmol/L). The disease activity was evaluated using The EULAR SjS disease activity index (ESSDAI) and its components. Correlation analyses were also performed for a possible correlation with disease characteristics and markers of activity. Results: No differences in 25 OH-D3 levels were found between SjS and healthy populations (p>0.05). No correla- tions were found between patient characteristics or labo- ratory values (p>0.05). Conclusions: This study did not find a link between disease characteristics and disease activity and 25 OH-D3 levels. Prospective studies with more patients should be conducted to reach a conclusion.Letter Citation - WoS: 1Citation - Scopus: 1About The Article Titled “a Different Scintigraphic Perspective On The Systolic Function Of The Left Ventricle-1” [“sol Ventrikül Sistolik Fonksiyonuna Sintigrafik Olarak Farklı Bir Bakış Açısı-1” Başlıklı Makale Hakkında](Galenos Publishing House, 2024) Taşçı, Cengiz[No abstract available]Article Citation - WoS: 1Citation - Scopus: 1Abstinence-Related Motivational Engagement Scale: Validity and Reliability in Turkish People(Bilimsel Tip Publishing House, 2018) Yavan, Tulay; Gulesen, Asli; Bebis, HaticeOBJECTIVES: This research aimed to conduct a validity and reliability study of the Turkish version of the abstinence-related motivational engagement (ARME) scale. MATERIALS AND METHODS: This study included 122 people and was administered in a smoking cessation clinic. The sociodemographic-smoking status characteristics questionnaire and the ARME scale were used for data collection. A psycholinguistic language adaptation was performed. In the validity, analyses, content, construct, and criterion-related validities were used. For content validity, expert evaluation was performed. For construct validity, principal component analyses (exploratory factor analyses) were performed. Orthogonal (Varimax) rotation was used to explore multiple factors. The Kaiser-Meyer-Olkin test was used to assess the adequacy of the sample size. For criterion-related validity, we compared the ARME scale points of people who were abstinent and had relapse for smoking at the end of the sixth month. In the reliability analysis, standard deviation (SD) and item analysis, internal consistency, and test-retest methods were used. RESULTS: The four factors explain 58% of the total variance. Items have factor loading between 0.409 and 0.805. When the factor structure of the scale was assessed, the items in each factor group have a factor load of at least 0.40. Due to one-dimensional use of the original scale, it has been decided to maintain this scale in its original form. The ARME scale points of people who quit smoking were statistically higher than the points of people who had relapse at the end of the sixth month. Cronbach's alpha coefficients were between 0.846 and 0.763. Significant and positive correlation was found between the test-retest scale scores. CONCLUSION: The Turkish adaptation of the ARME scale, which was developed for adults who quitted smoking, is an adequately valid and reliable measurement instrument. It is considered that the scale might be used reliably in different cultures as well.Article Citation - WoS: 6Citation - Scopus: 5Acrylamide-Encapsulated Glucose Oxidase Inhibits Breast Cancer Cell Viability(Walter De Gruyter Gmbh, 2020) Rrustemi, Trendelina; Geyik, Oyku Gonul; Ozkaya, Ali Burak; Ozturk, Taylan Kurtulus; Yuce, Zeynep; Kilinc, AliObjectives: Cancer cells modulate metabolic pathways to ensure continuity of energy, macromolecules and redoxhomeostasis. Although these vulnerabilities are often targeted individually, targeting all with an enzyme may prove a novel approach. However, therapeutic enzymes are prone to proteolytic degradation and neutralizing antibodies leading to a reduced half-life and effectiveness. We hypothesized that glucose oxidase (GOX) enzyme that catalyzes oxidation of glucose and production of hydrogen peroxide, may hit all these targets by depleting glucose; crippling anabolic pathways and producing reactive oxygen species (ROS); unbalancing redox homeostasis. Methods: We encapsulated GOX in an acrylamide layer and then performed activity assays in denaturizing settings to determine protection provided by encapsulation. Afterwards, we tested the effects of encapsulated (enGOX) and free (fGOX) enzyme on MCF-7 breast cancer cells. Results: GOX preserved 70% of its activity following encapsulation. When fGOX and enGOX treated with guanidinium chloride, fGOX lost approximately 72% of its activity, while enGOX only lost 30%. Both forms demonstrated remarkable resilience against degradation by proteinase K and inhibited viability of MCF-7 cells in an activity-dependent manner. Conclusions: Encapsulation provided protection to GOX against denaturation without reducing its activity, which would prolong half-life of the enzyme when administered intravenously.Article Citation - WoS: 2Citation - Scopus: 2Adrenomedullin Has No Effect on Segmental Bone Defect Healing but Increases Bone Mineral Density in Rat Model(AVES, 2023) Kaymakoğlu, Mehmet; Ciftci, E.; Korkusuz, P.; Ozdemir, E.; Erden, M.E.; Turhan, E.Objective: This study aimed to investigate the effect of adrenomedullin on the healing of the segmental bone defect in a rat model. Methods: Thirty-six Wistar rats were randomly divided into 6 groups based on follow-up periods and administered a dose of adreno-medullin hormone. In each group, bilaterally, a 2-mm bone defect was created at the diaphysis of the radius. Sodium chloride solution was administered to sham groups 3 times a week for 4 and 8 weeks intraperitoneally. Adrenomedullin was administered to the study groups 3 times a week: 15 μg—4 weeks, 15 μg—8 weeks, 30 μg—4 weeks, and 30 μg—8 weeks, respectively. After euthanasia, the segmental defects were evaluated by histomorphometric [new bone area (NBA)] and microtomographic [bone volume (BV), bone surface (BS), and bone mineral density (BMD)] analyses. Results: Although the 4-and 8-week 15 μg administered study groups had higher NBA values than the other study and control groups, the histomorphometric analysis did not reveal any statistical difference between the control and study groups regarding NBA (P >.05). In microtomographic analysis, BV was higher in the 15 μg 4-week group than 30 μg 4-week group (296.9 vs. 208.5, P =.003), and BS was lower in the 30 μg 4-week group than in the 4-week control group (695.5 vs. 1334.7, P =.005), but overall, no significant difference was found between the control and study groups (P >.05). Despite these minor differences in histomorphometric and microtomographic criteria indicating new bone formation, the BMD values of the 15 μg 8-week study group showed a significant increase compared with the control group (P =.001, respectively). Conclusion: Adrenomedullin positively affected BMD at 15 μg, but this study could not show healing in the segmental defect site at different dose regimens. Further studies are needed to assess its effects on bone tissue trauma. © 2023, AVES.

Despite many controversies about how Karagoz came into existence, there is a consensus that it emerged in the 16th century. Figures, as cultural objects, have production methods and techniques interwoven with the doctrines of the past. Today, figure-making for different purposes, inherited from the past, is present in Karagoz figure art. The aesthetic reflections, technique, and material harmony of the figures for show purposes must carry the cultural essence of Karagoz. This study examines museum collections and exhibitions, interviews with Karagoz masters, and a data analysis from an academic perspective. Considering these factors, it becomes clear that the training of masters for figure-making art is significant. Long-term training organized by institutions will contribute to this art and might be beneficial for good examples to reach the audience. Transferring the figures to future generations while preserving their cultural essence, making them in a suitable technique, and aesthetic understanding synthesized with modern techniques; will also contribute to the survival of this art.Article Citation - Scopus: 1Affecting Factors in Medication Adherence in Kidney Transplant Recipients(Aves, 2023) Ordin, Yaprak Sarigol; Karayurt, Ozgul; Ertan, Nermin; Edeer, Aylin Durmaz; Yildiz, SerkanObjective: This study aimed to determine the risk factors related to immunosuppressive medication adherence in kidney transplant recipients. Methods: The study adopted a retrospective design. It was carried out on 208 kidney transplant recipients. The social cognitive theory was used for understanding and addressing the issues of nonadherence to immunosuppressive medication. Data were collected with a self-reported-Immunosuppressant Therapy Adherence Scale and biological assays. Descriptive analyses and logistic regression were used to analyze data. Results: According to the self-reported assessment, medication adherence of the patients receiving transplants from live donors was 0.503 times lower than that of the patients receiving transplants from deceased donors. The biological assays did not show any affecting factors in medication adherence. Conclusion: The results of the study showed the importance of combining methods to assess medication adherence. In the self-reported assessment, live donor transplantation was found to negatively affect medication adherence. Turkiye is the country with the highest number of kidney transplantations from live donors in the world. Health professionals must be more careful in assessing medication adherence after live donor transplantations.Article Aile Hekimlerinin Sağlıklı Yaşam Biçimi Davranışlarının ve Klinik Uygulamalarında Yaşam Biçimi Tıbbının Değerlendirilmesi(Galenos Publishing House, 2025) Semin, Ilgi; Kazdağlı, Hasan; Gökdemir, ÖzdenAmaç: Bu çalışmanın amacı, aile hekimlerinin sağlıklı yaşam biçimi davranışlarını değerlendirmek ve klinik uygulamalarında yaşam biçimi tıbbına yönelik katılımlarını incelemektir. Yöntemler: Temmuz 2018 ile Ağustos 2019 tarihleri arasında aile hekimlerinden veri toplamak amacıyla çevrimiçi bir anket geliştirildi. Tanımlayıcı ve korelasyonel bir araştırma deseni kullanıldı. Çalışmada uygulanan anket, “katılımcıların kişisel bilgileri” ve “Sağlıklı Yaşam Biçimleri Davranış Ölçeği-II”i içermektedir. Kesitsel bir çalışma olarak tasarlanan bu araştırmada, örneklem kolayda örnekleme metodu ile sekiz ülkeden belirlenmiştir, ve anketler katılımcılara elektronik ortamda uygulanmıştır. Katılımcılara anketin süresi, veri saklama işlemleri, saklama süresi, araştırmacıların kimliği ve çalışmanın amacı hakkında bilgi verilmiştir. Bulgular: Çalışmaya 131 aile hekimi katılmış olup, erkek katılımcı oranı daha yüksek bulunmuştur. Sigara içme sıklığının Türk aile hekimleri arasında anlamlı derecede yüksek olduğu tespit edilmiştir (p=0,013). Ancak, ölçek toplam puanı veya altı boyutta alınan puanlar açısından aile hekimleri arasında istatistiksel olarak anlamlı bir fark bulunmamıştır. Sonuç: Çoğu aile hekimi, bu alanda daha fazla eğitim almak istediklerini belirtmiştir, bu da tıp fakültelerinin müfredatına eğitim müdahalelerin dahil edilmesi gerekliliğini göstermektedir. Ayrıca, iyi yapılandırılmış web tabanlı kitlesel çevrimiçi kurslar, aile hekimlerinin sağlıklı yaşam biçimi davranışları ve yaşam biçimi tıbbı uygulamalarına yönelik eğitim gereksinimlerini karşılamada etkili bir çözüm olabilir.Article Citation - WoS: 2Citation - Scopus: 2Analysis of Nucleotide Changes in Rt-Pcr Primer/Probe Binding Regions in Sars-Cov Isolates Reported From Turkey(Ankara Microbiology Soc, 2021) Demir, Ayse Banu; Bulgurcu, Alihan; Appak, Ozgur; Sayiner, Ayca ArzuThe SARS-CoV-2 virus, which caused the COVID-19 epidemic, caused more than 55 million cases and nearly 1.5 million deaths worldwide. For the microbiological diagnosis of the disease, the most valid method is detecting the presence of the viral genome by real-time reverse transcription polymerase chain reaction (rRT-PCR). However, due to the nature of the RNA viruses, frequent mutations may affect the sensitivity of the analyses made on the genetic material of the virus, such as PCR. In this study, we aimed to investigate the mutations in the primer-probe binding regions of the rRT-PCR panels used in COVID-19 diagnosis. SARS-CoV-2 whole genome sequence data (n= 194) isolated from COVID-19 cases in Turkey and uploaded on GISAID database from the centers in Istanbul (n= 78), Ankara (n= 58), Kars (n= 47), Bursa (n= 2), Adiyaman (n= 2), Erciyes (n= 1) and Kocaeli (n= 1) between March 17-September 14, 2020 were analyzed. In order to determine the nucleotide changes, SARS-CoV-2 sequences from Turkey were compared to the reference genome sequence (NC_045512.1) present in GenBank website. The constructed data set was aligned using the MAFFT program and was checked manually if the sequences were in the same frame by using the AliView program. Primer-probe binding sites of the thirteen SARS-CoV-2 rRT-PCR panels from seven different institutes (US CDC, China CDC, Charite CDC, Pasteur, HKU, Thailand, NIID) that are being used in COVID-19 diagnosis were evaluated in terms of nucleotide changes within the corresponding regions compared to the reference genome. Sequence diversities in the viral genomes were determined via positional nucleotide numerical calculator and entropy calculator modules and nucleotide and entropy changes in primer-probe binding regions for each rRT-PCR panel were examined. Among thirteen different primer-probe panels, nucleotide changes in the target regions of the seven primer-probe panels were determined. When viral sequences with nucleotide changes in the primer-probe binding regions were examined, the most common changes were observed in the China CDC N-forward primer and US CDC N3-forward primer binding regions. It is important that the kits to be used as diagnostic tests are designed specific to the regions with less nucleotide changes. Nucleotide changes may not be critical for DNA amplification for most PCR panels, but should be carefully monitored as they may affect the sensitivity of the assay. If the risk of alteration of the designed region is high, the primer - probe binding sites should be checked frequently and updated when necessary.Article Citation - WoS: 2Citation - Scopus: 3An Analysis of Physical and Psychological Expectations of Earthquake Victims From Temporary Shelters: a Design Proposal(Middle East Technical Univ, 2012) Yuksel, Belma; Hasirci, DenizThis study analyzes physical and psychological expectations of earthquake victims from temporary shelters and presents a design proposal. Interviews were conducted with earthquake victims in the city of Kocaeli in Turkey, and needs were identified. Also, user survey results from previous studies that have been conducted after the August 17th earthquake in 1999 were used to establish the design requirements for a temporary housing unit. While lack of space and issues of crowding, noise, and hygiene were mentioned as the most important problems in temporary earthquake shelters, suggestions to improve them included consideration of psychology and privacy needs of victims. The need for a home and not just a shelter has been identified and design guidelines have been examined.Article Citation - WoS: 14Citation - Scopus: 12Analysis of Risk Factors Affecting Mortality in Elderly Patients Operated on for Hip Fractures: a Retrospective Comparative Study(Turkish Assoc Orthopaedics Traumatology, 2021) Biçen, Ahmet Çağdaş; Akdemir, Mehmet; Turken, Mehmet Aykut; Cekok, Kubra; Ekin, Ahmet; Turan, Ahmet CemilObjective: The aims of this study were (1) to investigate the effects of different demographic and perioperative modalities on mortality rates and (2) to compare mortality rates between different implants in elderly patients operated on for hip fractures. Methods: In this retrospective study, a total of 314 patients who were operated on for hip fractures were included study. Patients were then divided into four groups based in their implant types: long-stem cementless bipolar hemiarthroplasty (n = 124; 102 female, 22 male; mean age = 84.2 +/- 6.4 years), standard-stem cementless bipolar hemiarthroplasty (n = 74; 48 female, 26 male; mean age = 83.5 +/- 6.9 years), antegrade intertrochanteric nail (n = 61; 35 female, 26 male; mean age = 78.5 +/- 6.8 years), and total hip arthroplasty (n = 55; 34 female, 21 male; mean age = 72.5 +/- 4.3 years). Data including gender, age, duration from injury to surgery, American Society of Anesthesiologists (ASA) score, comorbidities, use of antiplatelet agents, Barthel Index of Activities of Daily Living, type of anesthesia, operation time, preoperative hemoglobin values, blood transfusions given, duration of hospital stay, complications, and type of fracture were recorded. Results: Overall, the mean follow-up was 36.5 (range = 0 - 107) months. The overall mortality rate was 53.2%. The median survival duration was 44.2 +/- 5 months (range = 34.3 - 54). Survival rates were found significantly different among the groups (P = 0.001). In the first three years postoperatively, the mortality rate was higher in the standard-stem bipolar hemiarthroplasty group, but in the long-term follow-up, the long-stem bipolar hemiarthroplasty group exhibited the higher mortality rates. It was observed that some parameters had statistically significant effects on the mortality rates. Male gender, higher age, lower hemoglobin values, increased number of blood transfusions, ASA scores >= 3, the existence of >= 3 comorbidities were found as main predictors of increased mortality rates. Conclusion: The results of this study have shown that age, gender, preoperative hemoglobin levels, ASA scores, and comorbidities are significant factors affecting mortality in elderly patients operated on for hip fractures. Long-stem cementless bipolar hemiarthroplasty appears to show similar rates of mortality with standard-stem cementless bipolar hemiarthroplasty.Article Attitudes of Nursing Senior Students Towards the Use of Computers in Healthcare and Related Factors(Association of Executive Nurses, 2022) Söylemez, B.A.; Özgül, E.; Akyol, M.A.; Küçükgüçlü, Ö.Aim: This study was conducted to determine the attitudes of nursing senior students towards the use of computers in healthcare and related factors. Method: The descriptive and cross-sectional study was conducted with 162 senior nursing students in a faculty of nursing at a university between June and July 2021. Data were collected with the “Participant Information Form” and “Attitudes toward Computers in Healthcare Assessment Scale.” The SPSS 25.0 package program was used to evaluate the data. Socio-demographic data were given as numbers, mean, percentages, and standard deviation. Number, mean, percentage distributions, independent groups t-test, Mann Whitney-U test, One-way ANOVA test, and Pearson correlation test were used to analyze the data. Results: In this research, 67.9% of the 162 students were females, and the mean age was 22.43±1.50 years. The mean score of the students on the scale was 15.65±8.91. Status of owning a computer (t=2.729, p<0.01), frequency of computer usage (u=637.500, p<0.01), level of knowledge in using a computer (F=13.410, p<0.001), and status of computer use in nursing practices (t=4.244, p<0.001) were found to affect attitudes of nursing students towards the use of computers in healthcare. Conclusion: Senior nursing students were found to have a moderate attitude towards using computers in healthcare. Adopting more positive attitudes towards this area will increase the quality of nursing care and provide easier access to clinical data and charts. © 2022 The Authors.Article Citation - Scopus: 2Behavioral Immune System and Trypophobia(Klinik Psikiyatri Dergisi, 2022) Ozturk, Suleyman; Ceylan, Deniz; Demir, Ayse Banu; Kazdagli, Hasan; Erdeniz, BurakPathogens, which are the source of infectious diseases, have imposed a strong selection pressure on human evo-lution as one of the most important causes of human death during the natural selection process. As a result of this, it is assumed that a variety of adaptations have evolved against infection threats and one of these adap-tations is the physiological immune system. However, activation of the physiological immune system can be quite costly for organisms in some cases, and therefore it has been recently proposed in evolutionary psychology that an adaptive system called behavioral immune sys-tem may have evolved in association with the proactive functional processes against pathogen threats. Furthermore, it was hypothesized that a number of psy-chopathologies might develop as a result of maladaptive processes affecting the functionality of this system, and one of these psychopathologies might be trypophobia. Trypophobia refers to a psychological disorder in which individuals experience aversion and disgust at excessive levels toward clusters of small objects such as holes and bumps. Following this, the current review was estab-lished within the framework of three distinct goals. Firstly, this review aimed to discuss the evolutionary basis and mechanisms of the behavioral immune system. Secondly, the review aimed to discuss the characteristic features and the etiological explanations of trypophobia. Finally, the review aimed to discuss how potential changes in the behavioral immune system might lead to the development of trypophobia.Article Citation - Scopus: 2A Bibliometric Analysis of Publications on Emergency Medicine in Turkiye(Wolters Kluwer Medknow Publications, 2024) Guzelce, Mustafa Can; Orhan, Ertug; Ozgur, SeferOBJECTIVES: Publications and literature related to emergency medicine (EM) have been consistently increasing. There are 4048 studies in total in the EM journals published until the present day in Turkiye in the Web of Science (WoS) database. Our aim is to define the bibliometric features of scientific studies published in EM journals in Turkiye, to gain insights into the trends of the literature. METHODS: We retrospectively analyzed the bibliometric data of scientific studies published in EM journals in Turkiye until today on the WoS database related to the EM field. The bibliometrix package of R statistical software was used in the bibliometric analyses in the study. RESULTS: A total of 4048 scientific studies from Turkiye indexed on the WoS database from 10,263 authors in four different journals were analyzed. Among these, 3681 (90.9%) were articles, 188 (4.7%) were reviews, 97 (2.4%) were editorial material, 60 (1.5%) were letters, and 5 (0.1%) were corrections. Average number of citations per study was 3.6, with the most cited study having 2016 citations. The most frequent title's words were emergency, patient, and acute. CONCLUSION: This study shows that there is an increasing trend in the number of EM publications and citations in Turkiye with the first most cited study having 2016 citations, and the top contributing countries were Turkiye, Iran, and India. The results of this study may be useful in understanding the historical and prospective development of EM, including the identification of general information about its publications, differentiation of the top-cited ones, and presentation of a bibliometric analysis of scientific activity to date.Article Bioinformatics Based Drug Repurposing Approach for Breast and Gynecological Cancers: RECQL4/FAM13C Genes Address Common Hub Genes and Drugs(Galenos Publ House, 2025) Duran, Gizem AynaObjective: The prevalence of breast cancer and gynaecological cancers is high, and these cancer types can occur consecutively as secondary cancers. The aim of our study is to determine the genes commonly expressed in these cancers and to identify the common hub genes and drug components. Materials and Methods: Gene intensity values of breast cancer, gynaecological cancers such as cervical, ovarian and endometrial cancers were used from the Gene Expression Omnibus database Affymetrix Human Genome U133 Plus 2.0 Array project. Using the linear modelling method included in the R LIMMA package, genes that differ between healthy individuals and cancer patients were identified. Hub genes were determined using cytoHubba in Cytoscape program. “ShinyGo 0.80” tool was used to determine the disease-specific biological KEGG pathways. Drug.MATADOR from the ShinyGo 0.80 tool was used to predict drug-target relationships. Results: The RecQ Like Helicase 4 and Family with Sequence Similarity 13 Member C genes were found to be similarly expressed in breast cancer and gynaecological cancers. Upon KEGG pathway analyses with hub genes, Drug.MATADOR analysis with hub genes related to cancer related pathways was performed. We have determined these gene/drug interactions: NBN (targeted by Hydroxyurea), EP300 (targeted by Acetylcarnitine) and MAPK14 (targeted by Salicylate and Dibutyryl cyclic AMP). Conclusion: The drugs associated with hub genes determined in our study are not routinely used in cancer treatment. Our study offers the opportunity to identify the target genes of drugs used in breast and gynaecological cancers with the drug repurposing approach.Letter Can E-Cigarettes Be the Source of Lead Toxicity(AVES, 2025) Yılmaz, Seda; Kılınc, Oguz; Atik, Merve DemirciArticle Can Volumetric Magnetic Resonance Imaging Evaluations Be Helpful in the Follow-Up of Cognitive Functions in Cognitively Normal Parkinson's Disease Patients?(Tubitak Scientific & Technological Research Council Turkey, 2024) Uysal, Hasan Armağan; Hunerli, Duygu; Çakmur, Raif; Dönmez Çolakoğlu, Beril; Ada, Emel; Yener, GörsevBackground/aim: In this study, besides the evaluation of gray and white matter changes in cognitively normal Parkinson's disease (PDCN) patients with volumetric magnetic resonance imaging (MRI) parameters, it was tried to show that some neuropsychological tests may be impaired in PD-CN patients. Materials and methods: Twenty-six PD-CN patients and 26 healthy elderly (HC) participants were included in the current study. Global cognitive status was assessed using the mini-mental state examination (MMSE), and the Montreal cognitive assessment scale (MoCA). Attention and executive functions were evaluated using the Wechsler memory scale-revised (WMS-R) digit span test and trail making test (TMT) part A and part B, the Stroop test, semantic and phonemic fluency tests, and clock drawing test. Magnetic resonance imaging (MRI) was acquired according to the Alzheimer's disease neuroimaging initiative (ADNI) protocol. Results: There were no significant differences among groups regarding age, sex, handedness, and years of education. In the comparison of the PD-CN group and the HC group, there was a statistical decrease in the total animal scores, lexical fluency, TMT part A and TMT part B scores in the PD-CN group. Subcortical gray matter volumes (GMV) were significantly lower in PD-CN patients. The PD-CN group had a significantly reduced total volume of right putamen and left angular gyrus compared to that in the HC group. We observed that putamen and angular gyrus volumes were lower in PD-CN patients. On the other hand, TMT part B may be a useful pretest in detecting the conversion of mild cognitive impairment in PD. Conclusion: Significant MRI volumetric measurements and neuropsychological test batteries can be helpful in the clinical follow-up in PD-CN patients.Article Citation - WoS: 15Citation - Scopus: 14Changes on Hepatitis C Virus Genotype Distribution in Western Turkey: Evaluation of Twelve-Year Data(Aves, 2020) Duran, Alev Cetin; Cetinkaya, Ozgul Kaya; Sayiner, Ayca Arzu; Seydaoglu, Gulsah; Ozkaratas, Emre; Abacioglu, HakanBackground/Aims: Hepatitis C virus (HCV) prevalence is 1% in Turkey with genotype 1 being the predominant type traditionally. However unique geographical location of Turkey and increasing human migration in the region influences the epidemiology of the infection. The aim of this study was to determine the changes in distribution of HCV genotypes and risk factors. Materials and Methods: In this retrospective single-center study, HCV genotyping results of 558 patients were evaluated in between 2005 and 2016.Three different HCV genotyping assays were used during the 12-year study period;restriction fragment length polymorphism (RFLP), Abbott Real Time HCV Genotype II and Bosphore HCV genotyping kit. Results: The most prevalent HCV genotype was genotype 1 detected in 88.4% of the patients followed by genotype 3 (5.2%),genotype 4 (2.9%),genotype 2 (2.1%), mixed genotypes (1.1%) and genotype 5 (0.3%). Genotype 1a showed an increasing prevalence. There were 19 patients (3.4%) either of foreign nationalities or Turkish citizens living abroad. Genotype 3 was the most common type among these patients which 10.3% had intravenous drug use history. Syrian migrant population differed in terms of HCV genotypes. Genotype 5 detected in two Syrian patients, which is the first report of HCV type 5 in Western Turkey. Among the HCV genotype 4 infected patients, 31.3% were Syrians. Conclusion: Our study showed that although genotype 1b dominance continues, the distribution and prevalence of HCV genotypes are changing in our region mainly due to migration and increase in the frequency of patients with non-traditional risk factors such as intravenous drug use. Monitoring the epidemiology of HCV genotypes may provide guidance in treatment decisions.Article Citation - WoS: 9Citation - Scopus: 9Classical Heart Rate Variability and Non-Linear Heart Rate Analysis in Mice Under Na-Pentobarbital and Ketamine/Xylazine Anesthesia(Tubitak Scientific & Technical Research Council Turkey, 2022) Kazdagli, Hasan; Ozel, Hasan Fehmi; Ozbek, Mustafa; Alpay, Suheda; Alenbey, MuruvvetBackground/aim: Anesthetics are often used in animal experiments to achieve immobilization and relieve pain. However, many anesthetics can alter the dynamics of cardiovascular systems. We aimed to compare the effects of two frequently used anesthetics agents on heart rate variability (HRV) parameters in mice. Materials and methods: This observational study was performed between May and June 2014 in 21 male BALB/c mice aged 16-20 weeks. The animals were divided into three groups: pentobarbital (P), (n = 7); pentobarbital+fentanyl (P+ F), (n = 7); and ketamine+xylazine (K+X), (n = 7). Surface electrocardiography (ECG) electrodes were placed in lead II configuration. 'the tachogram of RR intervals was obtained after R waves were detected using the Pan-Tompkins real-time QRS recognition algorithm. Frequency-domain, time-domain, and nonlinear HRV analyses were performed. Results: The bradycardia effect was higher in the K+X group (p < 0.01). Time-domain indices were higher in group K+X compared to group P (p < 0.01) and group P+F (p < 0.001). Very low frequency (VLF) power was significantly lower in group K+X compared to group P and group P+F (p < 0.01). Low frequency (LF) power, low frequency/high frequency (LF/HF) ratio, and total power (TP) were higher in group K+X compared to group P (p < 0.01) and group P+F (p < 0.001). The detrended fluctuation analysis short-term parameter (DFA alpha(1)) was significantly higher in group K+X compared to group P+F (p < 0.05) and the long-term parameter (DFA alpha(2)) was lower in group K+X compared to group P (p < 0.05). Standard deviations SD1 and SD2 were higher in group K+X compared to group P (p < 0.001) and group P+F (p < 0.001), SD2/SD1 ratio was lower in group K+X compared to group P (p < 0.05) and group P+F (p < 0.05). Entropy measures did not differ between groups. Conclusion: HRV analyses, including nonlinear methods, indicated that a K+X combination reduces imbalance and disorder in the regulation of the autonomic nervous system (ANS) in comparison to both P and the P+F combination.Article Clinical Management Strategies of Cardiologists in Heart Failure with Reduced Ejection Fraction in Türkiye(Kare Publ, 2024) Türk, Uğur Önsel; Kocabaş, Umut; Özçalık, Emre; Kıvrak, Tarık; Altın, CihanAmaç: Kalp yetersizliği (KY) kılavuz önerilerinin klinik pratikte uygulanması zaman almaktadır ve genellikle gerçek yaşam şartlarında optimal düzeyde uygulanmamaktadır. Bu zorluğun önemli nedenlerinden biri hekim ile ilişkili faktörlerdir. Bu anket çalışmasının amacı, Türkiye’deki kardiyoloji uzmanlarının düşük ejeksiyon fraksiyonlu kalp yetersizliği (DEF-KY) tedavi tercihlerini belirlemektir. Yöntem: Anket çalışması 22 sorudan oluşmaktadır. Bu sorular, SurveyMonkey üzerinden yayınlanmış ve anket katılım linki birçok sosyal medya aracı üzerinden hekimlere ulaştırılmıştır. Bulgular: Anket çalışmasına Türkiye’de görev yapmakta olan 177 kardiyoloji uzmanı ve asistanı katıldı. Katılımcıların ortalama yaşı 39.5, %73.3’ü erkek, %38.7’si eğitim ve araştırma hastanelerinde görev yapmakta idi ve sadece %10.2’si kendisini KY uzmanı olarak tanımlamaktaydı. Katılımcıların %80.1’i, DEF-KY tanısı için sınır ejeksiyon fraksiyonu değerini %40 olarak kabul ettiklerini belirttiler. Hekimlerin %52.6’sı anjiyotensin reseptör-neprilisin inhibitörü (ARNi) tedavisini ‘‘en etkili KY tedavisi’’ olarak kabul ettiklerini belirtmelerine karşın, %62.7’si ilacın geri ödeme kısıtlılıkları ve fiyatı nedeniyle, DEF-KY tedavisine ARNi yerine anjiyotensin dönüştürücü enzim inhibitörü (ADEi) ile başlamak zorunda kaldıklarını belirttiler. Katılımcıların %52.3’ü tedaviye farklı bir KY ilaç sınıfını eklemenin, halihazırda kullanılan ilaçların dozunu arttırmaktan daha önemli olduğunu belirttiler. Hekimlerin %69.5’i yeni tanı KY hastalarında, hastane yatışı sırasında dört KY ilaç sınıfını aynı anda başlamanın mümkün olduğunu belirttiler. Buna karşın günlük pratiklerinde, sırasıyla ADEi/ARNI, beta–bloker, mineralokortikoid reseptör antagonisti ve sodyum-glukoz ko-transporter 2 inhibitörlerini başladıkları sıralı yaklaşımı daha çok tercih ettiklerini belirttiler. Sonuç: Bu anket çalışması, kılavuz önerileri ile gerçek yaşam uygulamaları arasında önemli farklılıklar olduğunu ortaya koymaktadır. Kılavuz önerilerinin, klinik pratikte uygulanabilmesi için sağlık sağlayıcıların gerekli önlemleri almalarına ve düzenlemeleri yapmalarına ihtiyaç vardır.
