Article Citation - WoS: 11Citation - Scopus: 9Antibiotic Use and Influencing Factors Among Hospitalized Patients With Covid-19: a Multicenter Point-Prevalence Study From Turkey(Galenos Publ House, 2022) Sencan, Irfan; Cag, Yasemin; Karabay, Oguz; Kurtaran, Behice; Guclu, Ertugrul; Ogutlu, Aziz; Agalar, CananBackground: Broad-spectrum empirical antimicrobials arc frequently prescribed for patients with coronavirus disease 2019 (COVID-19) despite the lack of evidence for bacterial coinfection. Aims: We aimed to cross-sectionally determine the frequency of antibiotics use, type of antibiotics prescribed, and the factors influencing antibiotics use in hospitalized patients with COVID-19 confirmed by polymerase chain reaction. Study Design: The study was a national, multicenter, retrospective. and single-day point prevalence study. Methods: This was a national, multicenter, retrospective, and single-day point-prevalence study, conducted in the 24-h period between 00:00 and 24:00 on November 18, 2020, during the start of the second COVID-19 peak in Turkey. Results: A total of 1500 patients hospitalized with a diagnosis of COVID-19 were included in the study. The mean age +/- standard deviation of the patients was 65.0 +/- 15.5, and 56.2% (n = 843) of these patients were men. Of these hospitalized patients, 11.9% (n = 178) were undergoing invasive mechanical ventilation or ECMO. It was observed that 1118 (74.5%) patients were receiving antibiotics, of which 416 (372%) were prescribed a combination of antibiotics. In total, 71.2% of the patients had neither a clinical diagnosis nor microbiological evidence for prescribing antibiotics. In the multivariate logistic regression analysis, hospitalization in a state hospital (p < 0.001), requiring any supplemental oxygen (p = 0.005). presence of moderate/diffuse lung involvement (p < 0.001), C-reactive protein >10 ULT coefficient (p < 0.001), lymphocyte count < 800 (p = 0.007), and clinical diagnosis and/or confirmation by culture (p <0.001) were found to be independent factors associated with increased antibiotic use. Conclusion: The necessity of empirical antibiotics use in patients with COVID-19 should be reconsidered according to their clinical, imaging, and laboratory findings.Article Comparison of Intraoperative Biliary Anastomosis Stenting Technique in Living-Donor Liver Transplantation: Review of 41 Patients(Turkiye Klinikleri, 2022) Dönmez, R.; Balas, Ş.; Göktuğ, U.U.; Emek, E.; Tokat, Y.Background/aim: Biliary fistula is one of the most important complications in liver transplantation. Complications can vary from simple local peritonitis to death, and various techniques have been described to prevent them. In this study, we compared two different stenting methods used in biliary tract anastomosis in living-donor liver transplantation. Material and methods: We retrospectively analyzed data from 41 living-donor liver transplantations that were performed due to end-stage liver failure between August 2019 and November 2020. Patients were grouped according to the stenting technique used in biliary anastomosis. Postoperative biliary tract complications were investigated. Results: Biliary fistulas were observed in 2 (7.4%) patients in the internal stent group, while 4 (28.5) fistulas were observed in the external stent group. Biliary tract stricture was observed in 2 (7.4%) patients in the internal stent group, but there was no statistical difference in complications. The preoperative MELD score (p = 0.038*) was found to be statistically significant in regard to developing complications. Conclusion: Our study did not show the effect of stenting methods used during biliary anastomosis on the development of complications. However, larger randomized controlled studies are needed. © TÜBİTAK.Article Dodder (Cuscuta sp.) Extract Prevents Cognitive Deficits in a Rat Model of Hepatic Encephalopathy(Kare Publ, 2024) Cevik, Ozge; Sen, Ali; Şener, Göksel; Ercan, Feriha; Doğan, Ahmet; Özbeyli, Dilek; Hatipoğlu, Bilge NurOBJECTIVE: In our study, the protective effect of dodder plant extract against encephalopathy induced by cholestatic liver disease model was investigated. METHODS: Spraque Dawley rats were used in the study. For the cholestatic liver disease model, the bile duct ligation (BDL) was applied. The groups were determined as control, Cuscuta sp. (CUS), BDL and BDL + CUS. Double ligation was performed in the bile duct in the BDL groups. For the applications, saline (SF) was administered to the control and BDL groups for 28 days while 250 mg/ kg of Cuscuta sp. extract was given by oral gavage to the CUS and BDL + CUS groups. At the end of the experiment, cognitive eval- uations were made by applying new object recognition and Morris water maze tests. After these tests, blood-brain barrier (BBB) measurements were made in half of the groups. In the other half of the groups, brain tissue samples were taken by decapitation and transforming growth factor-beta (TGF-β), 8-hydroxydeoxyguanosine (8-OHdG) and sodium-potassium adenosine triphospha- tase (Na+/K+-ATPase) measurements were made in the tissues. Histological examinations of the tissues were also performed. RESULTS: Cognitive performance was low, and BBB permeability was found to be increased in the group with bile duct liga- tion. In addition, TGF-β and 8-OHdG levels were increased in tissues, while Na+/K+-ATPase enzyme activity was suppressed. Treatment with Cuscuta sp. increased cognitive performance and decreased BBB permeability. Other biochemical parameters examined were significantly (p<0.05–0.001) reversed and supported by histological findings. CONCLUSION: Our findings in the study suggest that dodder plant may be beneficial for the protection of cognitive perfor- mance and brain tissue in encephalopathy caused by cholestasis. Keywords: Cuscuta sp.; cholestasis; encephalopathy; fibrosis.Article The Effect of 3d Modeling on Family Quality of Life, Surgical Success, and Patient Outcomes in Congenital Heart Diseases: Objectives and Design of a Randomized Controlled Trial(Turkish J Pediatrics, 2024) Sumengen, Aylin Akca; Ismailoglu, Abdul Veli; Ismailoglu, Pelin; Gumus, Terman; Celiker, Alpay; Namlisesli, Deniz; Cakir, Gokce NazBackground. Understanding the severity of the disease from the parents' perspective can lead to better patient outcomes, improving both the child's health -related quality of life and the family's quality of life. The implementation of 3 -dimensional (3D) modeling technology in care is critical from a translational science perspective. Aim. The purpose of this study is to determine the effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases. Additionally, we aim to identify challenges and potential solutions related to this innovative technology. Methods. The study is a two -group pretest -posttest randomized controlled trial protocol. The sample size is 15 in the experimental group and 15 in the control group. The experimental group's heart models will be made from their own computed tomography (CT) images and printed using a 3D printer. The experimental group will receive surgical simulation and preoperative parent education with their 3D heart model. The control group will receive the same parent education using the standard anatomical model. Both groups will complete the Sociodemographic Information Form, the Surgical Simulation Evaluation Form - Part I -II, and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module. The primary outcome of the research is the average PedsQL Family Impacts Module score. Secondary outcome measurement includes surgical success and patient outcomes. Separate analyses will be conducted for each outcome and compared between the intervention and control groups. Conclusions. Anomalies that can be clearly understood by parents according to the actual size and dimensions of the child's heart will affect the preoperative preparation of the surgical procedure and the recovery rate in the postoperative period.Article Citation - WoS: 1The Effect of myrtus Communis L. Extract on Nephrolithiasis Model in Rats(Kare Publ, 2024) Ertas, Busra; Dorucu, Dogancan; Gulerturk, Oznur; Sen, Ali; Cevik, Ozge; Cetinel, Sule; Sener, GokselOBJECTIVE: Nephrolithiasis is a common urological disease that can lead to renal failure. Oxidative stress has been shown to be a contributing factor for nephrolithiasis and many agents have been studied to prevent and treat oxidative stress-related nephrolithiasis and renal damage. Myrtus communis (MC) extract has been shown to be an important antioxidant in different animal models. In this study, MC extract was administered preventively or therapeutically to rats with kidney stones, and its effectiveness was investigated. METHODS: Wistar albino rats were divided into four groups (n=8); control (C), ethylene glycol (EG), EG+preventive MC, and EG+curative MC groups. The nephrolithiasis model was created by adding 0.75% EG to drinking water for 8 weeks. Ultimately, 24-hour urine was collected to measure calcium, citrate, and creatinine levels. After decapitation, kidney tissues were harvested for histological analyses, measurement of osteopontin and 8-hydroxydeoxyguanosine (8-OHdG) levels, and N-acetyl-beta-glucosaminidase (NAG), myeloperoxidase (MPO) and caspase-3 activities. RESULTS: In 24-hour urine samples, calcium, citrate and creatinine levels were decreased in the EG group, while oxalate levels were increased and in treatment groups these parameters returned to control levels. MPO, 8-OHdG, caspase-3 and NAG activity were significantly increased in tissue and these changes were reversed in both MC groups. Histological findings also supported the biochemical parameters. CONCLUSION: MC can reduce oxidative stress and histopathological changes in kidney tissues in rat nephrolithiasis model when used as either a preventive or therapeutic agent. If supported with further clinical trials, MC might have clinical implications in preventing oxidative renal cell injury and ultimately kidney stone formation.Article Citation - WoS: 5Citation - Scopus: 5Effects of myrtus Communis L. Extract and Apocynin on Lens Oxidative Damage and Boron Levels in Rats With a High Fat-Diet(Galenos Publ House, 2021) Yasar, Ruya Kuru; Kuru, Dilruba; Sen, Ali; Sener, Goksel; Ercan, Feriha; Yarat, AysenObjectives: Nutritional obesity causes oxidant damage in the body and cataract formation in the lenses by increasing the formation of free radicals. Myrtus communis leaf extracts (Myr) have antioxidant properties, and apocynin (Apo) is an effective NADPH-oxidase inhibitor. The data on tissue boron levels are quite lacking. The aim of this novel study was to investigate the effects of Myr and Apo treatment on boron levels and oxidative lens damage in rats fed a high-fat diet (HFD). Materials and Methods: Wistar albino male rats were randomly divided into four groups: the control group, HFD group, HFD + Myr group, and HFD + Apo group. Body weight and blood lipids were determined before and after the experiment. After decapitating the rats, the lenses were removed and homogenized. Catalase (CAT) and superoxide dismutase (SOD) activities and boron, malondialdehyde (MDA), and reduced glutathione (GSH) levels in the lens homogenates were determined. Results: The HFD increased serum triglyceride (p<0.05), total cholesterol level (p<0.001), body weight (p<0.001), and lens MDA levels (p<0.01) and decreased lens GSH (p<0.05) and boron level (p<0.01), SOD (p<0.001), and CAT activity (p<0.001). However, Myr and Apo treatment reduced the rats' body weight (p<0.001), serum triglyceride (p<0.05), and total cholesterol level (p<0.001) and increased lens boron (p<0.01; p<0.001), GSH levels (p<0.05; p<0.01), and CAT activity (p<0.001). Conclusion: Both Myr and Apo may be able to reduce oxidative stress in the lenses of obese rats caused by HFD by increasing boron levels.Article Citation - Scopus: 1Ethanolic Extract of Cotinus Coggygria Leaves Attenuates Crystalluria and Kidney Damage in Ethylene Glycol-Induced Urolithiasis in Rats(Kare Publishing, 2023) Gumru, S.; Ozgur, G.; Ertas, B.; Sen, A.; Eker, P.; Sener, T.E.; Sener, G.OBJECTIVE: Nephrolithiasis is a common cause of kidney insufficiency. Nephrolithiasis is proven to be the result of various biochemical and inflammatory processes that result in crystal formation and subsequent aggregation. Cotinus coggygria L. (CCog) is a plant extract which has been used as a Turkish remedy for kidney stones. With this study, we planned to evaluate the effects of CCog extract in ethylene glycol (EG)-induced nephrolithiasis model in rats. METHODS: The study group comprised 32 Wistar albino rats which were divided into Control (C), EG, CCog Prophylaxis (CC+EG+CC), and CCog Treatment (EG+CC) groups. Stone formation was induced by adding EG (0.75%) into rat’s drinking water. Normal drinking water was given to Control group for 8 weeks. Throughout the study period of 8 weeks, EG group was given only EG (0.75%) and CC+EG+CC group was given both EG and CCog. In EG+CC group, EG (0.75%) was given for 8 weeks whereas CCog was given for the past 4 weeks. After the 8th week, 24-h urine samples were collected. Rats were then sacrificed and kidney tissue samples were harvested. RESULTS: Metabolites (calcium, citrate) and creatinine in 24 h urine samples were decreased in CC+EG+CC and EG+CC groups. While hyperoxaluria was observed in the EG group, oxalate levels were similar to control levels in the P-CCog and C-CCog groups. The N-acetyl-β-glucosaminidase and myeloperoxidase activities were both increased in EG group and these parameters were significantly decreased on CCog treatment. CONCLUSION: We can conclude that C. coggygria extract can have beneficial effect on lowering concentration of stone-forming metabolites in urine and consequently protect renal tissues from damage due to nephrolithiasis. C. coggygria extract can be considered as a potential prophylactic and therapeutic option in high-risk stone formers. Furthermore, our data confirm ethnobotanical use of CC against nephrolithiasis. © 2023 by Istanbul Provincial Directorate of Health.Article Citation - WoS: 1Citation - Scopus: 1Evaluation of Coping Mechanism of Mothers of Children With Chronic Diseases During Coronavirus Disease 2019 Pandemic(Aves, 2024) Erkut, Zeynep; Kose, Selmin; Savaser, Sevim; Kaya, Gizem; Ogut, Nehir UluAIM: The aim of this study was to determine the problems, perceived stress, and coping with the stress of mothers of children with chronic diseases during the pandemic. METHODS: The study was conducted with cross-sectional design. The data were gathered from the mothers of children with chronic diseases who were followed up at the endocrine outpatient clinic of a hospital in Istanbul between February 1, 2021, and May 31, 2021. The data were collected by conducting face-to-face interviews with mothers of 117 children through information form, Perceived Stress Scale (PSS), and the Coping with Stress Scale (CSS). RESULTS: It was determined that 35.9% of the mothers stated that they had problems during the pandemic since their children suffered from chronic diseases. The mean scores of the mothers were 26.88 +/- 6.69 points for the PSS and 87.35 +/- 11.04 points for the CSS and there was a negative and weak correlation between their scale scores (r = -.190; p < .05). CONCLUSION: It was found that families faced many different problems during the pandemic, such as the treatment and control of their children. In case of extraordinary situations such as pandemics, nurses should provide planned guidance and counseling services to children with chronic diseases and their families in order to manage the negative situations they experience.Article Citation - WoS: 4Citation - Scopus: 4Evaluation of Psychosocial Outcomes of Living Liver Donors in Liver Transplantation(Aves, 2022) Ordin, Yaprak Sarigol; Seren, Arzu Kader Harmanci; Karayurt, Ozgul; Kul, Gulay Aksu; Kilic, Murat; Bozoklar, Cemal Ata; Tokat, YamanBackground: The purpose of this study was to evaluate the risk factors affecting psychosocial outcomes of living liver donors after liver transplantations. Methods: This was a descriptive, cross-sectional study. The sample consisted of living liver donors followed by 2 liver transplantation centers in 2 private hospitals in 2 different provinces, between August 2017 and October 2019. All the living liver donors were contacted without a time frame after donation and all the participants were evaluated once. The Beck Depression Scale, SF-36, General Self-Efficacy Scale, and Perceived Available Support Scale were used to collect data. The t-test, Kruskal-Wallis test, Mann-Whitney U-test, and Pearson correlation analysis were used for data analysis. Results: The mean age of the patients was 34.31 +/- 8.22 years. There was a positive, weak correlation between age and physical function. Gender, marital status, financial status, and education levels significantly affected physical components, social function, vitality, depression, and self-efficacy scores. High depression levels negatively affected the physical component, self-efficacy, and social support scores of the living liver donors. High self-efficacy positively affected social support. Conclusion: The study revealed that gender, marital status, employment status, and education levels were associated with psychosocial outcomes. The financial status was the main factor affecting each psychosocial variable. Financial status needs to be assessed in detail before and after the operation.Article Citation - WoS: 2Citation - Scopus: 2Global Health Emergencies During the Pandemic and Their Solutions(2021) Sencan, Irfan; Bulut, Dilek; Agalar, Canan; Sencan, Ismail HakkiAbstract: In this review, we evaluated health care problems, which were not common before pandemic outbreak but have been common issues after its appereance and approaches to control pandemic considering its influences on people. We revised current health care developing approaches under the light of experience obtained throughout the pandemic so far. The aim is to be prepared in advance for possible upcoming pandemics. As in Covid 19 pandemics, such long lasting and widely affecting situations, durability is also very important together with flexibility and quickness. To provide durability, we need global policies taking the health to its center as well as health system policies.Key words: Covid-19, health system, emergency, crisis, vulnerability, durabilityArticle Citation - Scopus: 1In Silico Evaluation of H1-Antihistamine as Potential Inhibitors of SARS-CoV RNA-Dependent RNA Polymerase: Repurposing Study of COVID-19 Therapy(Turkish Pharmacists Association, 2024) Küçükgüzel, İlkay; Kulabaş, Necla; Hamdan, MazınIntroduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), from the family Coronaviridae, is the seventh known coronavirus to infect humans and cause acute respiratory syndrome. Although vaccination efforts have been conducted against this virus, which emerged in Wuhan, China, in December 2019 and has spread rapidly around the world, the lack of an Food and Drug Administration-approved antiviral agent has made drug repurposing an important approach for emergency response during the COVID-19 pandemic. The aim of this study was to investigate the potential of H1-antihistamines as antiviral agents against SARS-CoV-2 RNA-dependent RNA polymerase enzyme. Materials and Methods: Using molecular docking techniques, we explored the interactions between H1-antihistamines and RNA-dependent RNA polymerase (RdRp), a key enzyme involved in viral replication. The three-dimensional structure of 37 H1-antihistamine molecules was drawn and their energies were minimized using Spartan 0.4. Subsequently, we conducted a docking study with Autodock Vina to assess the binding affinity of these molecules to the target site. The docking scores and conformations were then visualized using Discovery Studio. Results: The results examined showed that the docking scores of the H1-antihistamines were between 5.0 and 8.3 kcal/mol. These findings suggested that among all the analyzed drugs, bilastine, fexofenadine, montelukast, zafirlukast, mizolastine, and rupatadine might bind with the best binding energy (< -7.0 kcal/mol) and inhibit RdRp, potentially halting the replication of the virus. Conclusion: This study highlights the potential of H1-antihistamines in combating COVID-19 and underscores the value of computational approaches in rapid drug discovery and repurposing efforts. Finally, experimental studies are required to measure the potency of H1-antihistamines before their clinical use against COVID-19 as RdRp inhibitors.Article Measuring Shoulder Abduction Strength Using 2 Different Dynamometers: Comprehensive Intrarater and Interrater Reliability and Validity(Turkish Assoc Orthopaedics Traumatology, 2025) Atli, Ecenur; Topaloglu, Mahir; Hosbay, Zeynep; Ozdincler, Arzu RazakObjective: The purpose of this study is to investigate the intrarater and interrater reliability of handheld dynamometer (HHD) measurements in assessing isometric muscle strength of the shoulder abductors and to compare these results with those obtained using a fixed dynamometer (FD). Methods: The study involved 25 voluntary participants, all over the age of 18, asymptomatic (with no injuries in the upper extremity), and not engaged in overhead sports. The participants were evaluated twice by 2 different testers who were experienced in orthopedic rehabilitation, at 90 degrees of shoulder abduction in the scapular plane. On the first measurement day, Tester 1 performed measurements using both HHD and FD, while on the second measurement day, both testers used only the HHD. A 3-to 7-day interval separated the 2 measurement sessions. Paired-samples t-tests were used to evaluate the systematic bias between the testers. Spearman's rank correlation coefficient, intraclass correlation coefficient, standard error of measurement, and minimal detectable change were calculated. The statistical significance level was accepted as P < .05. Results: Data from 22 participants (15 women, 7 men; mean age: 23.00 +/- 3.19 years) were analyzed, as 3 individuals did not attend the final assessment. A strong correlation (r = 0.772) was found between Tester 1's HHD measurements and FD, while a similarly strong correlation (r = 0.748) was observed for Tester 2's HHD measurements. Excellent intrarater reliability (intraclass correlation coefficient [ICC]= 0.941) was found between Tester 1's measurements, and excellent interrater reliability (ICC= 0.889) was found between testers. Conclusion: Handheld dynamometer has demonstrated excellent interrater and intrarater reliability and high validity for assessing shoulder abductor muscle strength in research and clinical use. Since the muscle strength of testers using the HHD may influence the results, the FD may be a more appropriate option when the study population is stronger than the testers. Studies involving different clinical populations and testers with varying experience levels are needed to improve the relevance of the results.

This study aims to discuss the molecular epidemiology of CRAB isolates in Turkiye in the last 12 years and the prevalence of gene regions associated with resistance or pathogenesis using a systematic review method. Our study consists of a literature search, determination of eligibility and exclusion criteria, qualitative analysis of studies, data extraction, and statistical analysis. All studies were analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. The incidence rates of blaOXA-23, blaOXA-23-like, blaOXA-24/40, blaOXA-24/40-like, blaOXA-51, blaOXA-51-like, blaOXA-58, and blaOXA-58-like genes in CRAB strains were 76.4%, 68.6%, 1.2%, 3.4%, 97.0%, 98.6%, 8.4%, and 17.1%, respectively. It was determined that the prevalence of the blaOXA-23 and blaOXA-58 gene regions showed a statistically significant change over the years. Due to the high prevalence of A. baumannii strains carrying the blaOXA-23 variant, it is necessary to follow its geographical distribution and transposon and plasmid movements. Based on available data, molecular surveillance of CRAB strains should be standardized. In addition, sterilization and disinfection processes applied within the scope of an effective struggle against CRAB strains that can remain live on surfaces for a long time should be reviewed frequently.Article Citation - WoS: 2Citation - Scopus: 2Multidrug Resistance in Pathogens of Community-Acquired Urinary Tract Infections in Turkey: a Multicentre Prospective Observational Study(Tubitak Scientific & Technological Research Council Turkey, 2023) Sencan, Irfan; Karabay, Oguz; Altay, Fatma Aybala; Suzuk Yildiz, Serap; Simsek, Husniye; Gozukara, Melih Gaffar; Surme, SerkanBackground/aim: To have country-wide information about multidrug resistance (MDR) in isolates from community-acquired urinary tract infections (CAUTI) of Turkey, in terms of resistance rates and useful options.Materials and methods: We used a geocode standard, nomenclature of territorial units for statistics (NUTS), and a total of 1588 community-acquired isolates of 20 centres from 12 different NUTS regions between March 2019 and March 2020 were analysed. Results: Of the 1588 culture growths, 1269 (79. 9%) were Escherichia coli and 152 (9.6%) were Klebsiella spp. Male sex, advanced age, and having two or more risk factors showed a statistically significant relation with MDR existence (p < 0.001, p: 0.014, p < 0.001, respectively) that increasing number of risk factors or degree of advancing in age directly affects the number of antibiotic groups detected to have resistance by pathogens. In total, MDR isolates corresponded to 36.1% of our CAUTI samples; MDR existence was 35.7% in E. coli isolates and 57.2% in Klebsiella spp. isolates. Our results did not show an association between resistance or MDR occurrence rates and NUTS regions.Conclusion: The necessity of urine culture in outpatient clinics should be taken into consideration, at least after evaluating risk factors for antibacterial resistance individually. Community-acquired UTIs should be followed up time-and region-dependently. Antibiotic stewardship programmes should be more widely and effectively administrated.Article Citation - WoS: 2Citation - Scopus: 2Preparation and Application of Caffeic Acid Imprinted Polymer(Tubitak Scientific & Technological Research Council Turkey, 2023) Ersoy, Seyda K. A. R. A. M. A. N.; Tutem, Esma; Baskan, Kevser SoeZGEN; Apak, ResatIn the present study, molecularly imprinted polymers were synthesized using caffeic acid (CA) as a template molecule and then used for the extraction of CA and chlorogenic acid (CLA) from complex matrices. Syntheses were carried out in tetrahydrofuran as porogenic solvent using 4-vinyl pyridine, methacrylic acid, acrylamide, and 1-vinyl imidazole as monomers, ethylene glycol dimethacrylate as crosslinker and 2,2'-azobisisobutyronitrile as initiator. In polymerization processes, different ratios of the template:monomer:crosslinker (T:M:CrL) were used to obtain the most suitable polymer. Caffeic acid:4-vinylpiridine:ethylene glycol dimethacrylate's 1:4:16 mole ratio of MIP was determined as the most convenient polymer for CA recognition. In addition, nonimprinted polymers (NIPs) without templates were prepared. Dynamic and static adsorption tests were applied to determine the absorption features of the NIPs and CA-MIPs. Separation and purification studies of CA and CLA were performed with molecular imprinted solid phase extraction (MISPE) application. All steps of MISPE (loading, washing, elution) were optimized by HPLC analysis.Article Citation - WoS: 3Psychometrics of Stanford Presenteeism Scale-Short Form in Turkish(Cordus, 2022) Teoman, Ezgi; Seren, Arzu Kader HarmanciAIM: Presenteeism means that employees feel obliged to go to work even if there is a real problem that they cannot work.The main purpose is to to adapt the "Stanford Presenteeism Scale-Short Form" into Turkish on Nurses. METHOD: This is a methodological study. The study sample included the nurses working at the medical and surgical clinics of two public hospitals in 2017 in Istanbul. A total of 290 nurses participated in the study. Language, content, construct validities, total item correlation analysis, Kaiser Meyer Olkin, Bartlett tests, confirmatory and explanatory factor analysis (EFA), stability, and Cronbach's alpha reliability analyses were tested. RESULTS: The content validity index of the scale was.92. Two items that have correlation values below.40 were removed from the Turkish form. Cronbach's alpha internal consistency coefficient was.762. The structure of the four-item and single-factor Turkish form was confirmed. CONCLUSION: Stanford Presenteeism Scale-Short Form is a valid and reliable tool for the nurses in Turkey. It is recommended to be used among nurses in different studies. Hospital and nursing care service managers should deal with "presenteeism," since it is becoming a critical health human resource workforce issue. Health care managers may use this tool to evaluate the presenteeism level of their employees.Article Citation - WoS: 3Citation - Scopus: 4Qualitative and Artificial Intelligence-Based Sentiment Analysis of Turkish Tweets Related To Schizophrenia(Turkiye Sinir ve Ruh Sagligi dernegi, 2023) Dikec, Gul; Oban, Volkan; Usta, Mirac BarisObjective: The aim of this study was to qualitatively examine Turkish tweets about schizophrenia in respect of stigmatization and discrimination within a one-month period and to conduct emotional analysis using artificial intelligence applications. Method: Using the keyword 'schizophrenia,' Turkish tweets were gathered from the Python Tweepy application between December 19, 2020 and January 18, 2021. Features were extracted using the Bidirectional Encoder Representations from Transformers (BERT) method and artificial neural networks and tweets were classified as positive, neutral, or negative. Approximately 5% of the tweets were qualitatively analyzed, constituting those most frequently liked and retweeted. Results: The study found that, of the total of 3406 schizophrenia-related messages shared in Turkey over a period of one-month, 2996 were original, and were then retweeted a total of 1823 times, and liked by 25,413 people. It was determined that 63.4% of the tweets shared about schizophrenia contained negative emotions, 28.7% were neutral, and 7.71% expressed positive emotions. Within the scope of the qualitative analysis, 145 tweets were examined and classified under four main themes and two sub-themes; namely, news about violent patients, insult (insulting people in interpersonal relationships, insulting people in the news), mockery, and information. Conclusion: The results of this study showed that the Turkish tweets about schizophrenia, which were emotionally analyzed using artificial intelligence were found often to contain negative emotions. It was also seen that Twitter users used the term schizophrenia, not in a medical sense but to insult and make fun of individuals, frequently shared the news that patients were victims or perpetrators of violence, and the messages shared by professional branch organizations or mental health professionals were primarily for conveying information to the public.Article Citation - WoS: 1Citation - Scopus: 1Synthesis, Characterization, and Antimicrobial Evaluation of Some Novel Hydrazinecarbothioamides(Galenos Publishing House, 2025) Güler, Emrah; Dinç, Harika Öykü; Dincel, Efe Doğukan; Güzeldemirci, Nuray Ulusoy; Başoğlu-ünal, Faika; Kuran, Ebru DıdemObjectives: This study focused on synthesizing and characterizing novel thiosemicarbazide derivatives containing a 1,2,4-triazole moiety and evaluating their antimicrobial activity against several bacterial strains. The research aimed to identify key structural features that enhance antimicrobial efficacy through structure-activity relationship analysis and identify the minimum inhibitory concentration (MIC) of the most potent compounds to assess their potential for further development as antimicrobial agents. Materials and Methods: Nine novel thiosemicarbazide derivatives containing a 1,2,4-triazole moiety were synthesized by reacting 1,2,4-triazole derivatives with thiosemicarbazide precursors, and the products were characterized using infrared spectroscopy, proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR) spectroscopy, and elemental analysis. The antimicrobial activity of these compounds (5a-i) was tested against Klebsiella pneumoniae (K. pneumoniae), Escherichia coli, Staphylococcus aureus, Enterococcus faecalis, and Pseudomonas aeruginosa (P. aeruginosa), using microdilution, disk diffusion, and broth microdilution methods. Dimethyl sulfoxide was used as a negative control, and Vancomycin and Meropenem were used as positive controls, with all results converted to µM for consistent analysis. Results: The synthesized thiosemicarbazide derivatives (5a-i) were confirmed to be structurally correct through Fourier-transform infrared spectroscopy, 1H-NMR, and 13C-NMR spectroscopy. Among the tested compounds, 5e (4-bromophenyl) and 5g (n-propyl) showed significant antimicrobial activity, with 5g exhibiting the strongest effects against S. aureus and P. aeruginosa. Other derivatives, such as 5b (4-NO2Ph), 5c (4-FPh), and 5d (4-ClPh), showed moderate activity, while no significant activity was observed against K. pneumoniae or E. faecalis. Conclusion: The study successfully synthesized a series of novel thiosemicarbazide derivatives with a 1,2,4-triazole moiety and evaluated their antimicrobial potential. Compounds 5e and 5g exhibited significant antibacterial activity, particularly against S. aureus and P. aeruginosa, with MIC values in the low micromolar range. These findings suggest that the compounds hold promise as potential antimicrobial agents, and further studies should focus on optimizing their efficacy and exploring their mechanism of action.
