Article Consensus Paper on Candida Auris by Türkiye EKMUD, ID-IRI, THSK of Ministry of Health of the Republic of Türkiye, KLIMUD, TMC, TARD, and TYBD(Tubitak Scientific & Technological Research Council Turkey, 2025) Agalar, Canan; Erdem, Hakan; Cag, Yasemin; Arda, Bilgin; Balik, Recep; Bastug, Aliye; Arikan Akdagli, Sevtap; Sarı, Nagehan Didem; Uzun, Omrum; Arikan-akdagli, Sevtap; Utku, Tughan; Kalkanci, AyseCandida auris is an emerging fungal pathogen that has become a critical global health concern due to its high antifungal resistance and potential to cause nosocomial outbreaks. Since its initial identification in Japan in 2009, C. auris has spread rapidly, posing significant treatment challenges across various healthcare settings worldwide. The biofilm formation ability of C. auris enhances its resilience against disinfectants and antifungal agents, complicating infection control in healthcare environments. This consensus report was developed by a collaboration between several Turkish medical societies including the Turkish Society of Infectious Diseases and Clinical Microbiology Specialty (EKMUD), the Turkish Society of Anesthesiology and Reanimation (TARD), the Turkish Intensive Care Society (TYBD), the Infectious Diseases-International Research Initiative (ID-IRI), the Clinical Microbiology Specialist Society (KLIMUD), the Turkish Microbiology Society (TMC), and the Public Health Institution of T & uuml;rkiye (PHIT) under the Ministry of Health. The report provides a comprehensive overview of C. auris and its management, with a focus on the epidemiology, antifungal resistance mechanisms, recommendations for diagnostic and therapeutic challenges, infection control and prevention measures, and surveillance of C. auris. This consensus report aims to establish standardized diagnostic protocols, improve national surveillance systems, and promote effective infection control measures to mitigate C. auris-related health risks in T & uuml;rkiye. It also offers comprehensive national recommendations and addresses the need for interinstitutional collaboration, improve public health, and strengthen the healthcare response to this pathogen.Article Citation - WoS: 3Citation - Scopus: 3Antioxidants, Enzyme Inhibitory Activities, and Phytochemical Profiles of Seven Medicinal Plants Grown With Organic Farming Techniques(Tubitak Scientific & Technological Research Council Turkey, 2023) Zor, Murat; Ozupek, Burcin; Pekacar, Sultan; Deliorman Orhan, Didem; Orhan, Didem DeliormanIn this study, the potential antihyperlipidemic, antidiabetic, and antiobesity effects of extracts obtained via infusion techniques from Artemisia absinthium L., Achillea millefolium L., Calendula officinalis L., Fumaria officinalis L., Mentha piperita L., Origanum onites L., and Urtica dioica L. grown with organic farming techniques were investigated using enzyme inhibition methods (alpha-glucosidase, pan-creatic cholesterol esterase, pancreatic lipase, and alpha-amylase). It is important that natural compounds or extracts to be used in the treat-ment of metabolic problems have antioxidant effects. The antioxidant effects of these species were tested in terms of ABTS and DPPH radical scavenging activity, ferric reducing power, and metal chelating capacity. Extracts (2 mg/mL) of M. piperita (91.43 +/- 0.90%) and O. onites (70.18 +/- 2.02%) showed potent inhibitory effects on the alpha-glucosidase enzyme. Among all species, only O. onites extract ex-erted an inhibitory effect on the cholesterol esterase enzyme close to that of reference compound simvastatin. While all extracts were effective in the tested antioxidant activity methods, it was determined that the M. piperita and O. onites extracts displayed particularly significantly strong activities in terms of ferric reducing power, ABTS radical scavenging effect, and metal chelating capacity. The total flavonoid and phenolic contents of all extracts were determined. The compositions of the most active extracts were analyzed for pheno-lic acids and flavonoids using RP-HPLC. The results of RP-HPLC analysis showed that the levels of ellagic acid (0.923 +/- 0.000 g/100 g extract) in the M. piperita extract and rosmarinic acid (0.813 +/- 0.003 g/100 g extract) in the O. onites extract were high. As a result, all species grown with organic farming techniques except U. dioica were found to have high antioxidant effects. In light of these findings, it was concluded that M. piperita and O. onites grown with organic farming techniques showed strong inhibitory effects in terms of the tested activities, especially for alpha-glucosidase and pancreatic cholesterol esterase, and that in vivo studies and activity-guided isolation studies should be conducted on these species in the future.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: 4Citation - Scopus: 3Multidrug 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, Serkan; Engin, Derya Öztürk; Cag, Yasemin; Kul, Gülnur; Habip, Zafer; Kaya, Safak; Tasbakan, MeltemBackground/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: 2Global Health Emergencies During the Pandemic and Their Solutions(Tubitak Scientific & Technological Research Council Turkey, 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 Design and Implementation of a Low Cost and Portable Tactile Stimulator Br(Tubitak Scientific & Technological Research Council Turkey, 2022) Kazma, Coskun; Levent, Vecdi Emre; Cardak, Merve; Aydin, NizamettinWhen central nervous system has a problem, somatic area I and II respond to stimulation differently. Therefore, it is possible to identify some of the central nervous diseases when somatosensory on the fingertip is stimulated and responses are recorded and analyzed. We designed a system to stimulate the mechanoreceptors on fingertips. It is composed of a mechanical system for fingertip stimulation, an embedded controller, a control computer, and a software to control overall operation. During test, mechanoreceptors are stimulated according to the test protocols. Individuals' answers are recorded to be evaluated by the developed software. In this study, several design approaches for embedded controller were also examined and an FPGA based controller with the same functionality but higher performance was implemented. A test procedure was performed on 51 individuals at the department of pediatric psychiatry in a hospital, to investigate whether the sex has an effect on attention deficit and hyperactivity disorder.
