RESUMO
Excited-state intramolecular proton transfer (ESIPT)-based fluorescent molecules offer several exciting applications and are utilized most frequently as a cell imaging agent. Because of this, four distinct imidazole derivatives with ESIPT emission have been synthesized, and their fluorescence characteristics have been assessed in a variety of settings. Measurements using fluorescence spectroscopy have shown a promising candidate for cell staining, and potential candidate was specifically investigated for cell imaging uses in HT-29, MDA-MB-231, and HaCaT. Cytotoxicity of candidate molecule (1d) was analyzed using HT-29 and HaCaT cell lines, and at a dosage of 160 µM, HT-29 and HaCaT cell lines showed no signs of important cell toxicity. When spectroscopically measured, compound 1d showed no fluorescence ability in phosphate-buffered saline (PBS) solution. However, after 8 h of incubation in several cell lines, excellent fluorescence characteristics were seen in the green and red filters.
RESUMO
AIM: This study aims to assess the general health status and factors affecting the general health status in the 0-14 age group in Turkey. METHODS: This cross-sectional study was conducted using the Turkish Statistical Institute Turkey Health Survey 2022 micro data set. RESULTS: This study included 7019 participants. Household heads described the general health status of 91.3% of children and the dental and gum status of 82.4% of children as very good or good, and 9.2% of children had any chronic disease. Although the median breastfeeding duration was 15 months, there is statistical significant association between sex and general health status (p = 0.014) and sex and duration of breastfeeding (p = 0.006). A statistical difference was found between duration of breastfeeding and general health status (p = 0.009) and dental and gum status (p = 0.001). CONCLUSION: In 2022, the majority of children in Turkey had very good or good general health and dental and gum status. More than a third of children were breastfed for less than 12 months. Considering the possibility of neglecting oral and dental health problems, it is recommended to prioritize oral and dental health literacy trainings and to continue breastfeeding promotion programmes.

BACKGROUND: Ovarian cancer, also known as a silent killer, is the deadliest gynecological cancer in women worldwide. Epithelial ovarian cancers constitute the majority of ovarian cancers, and diagnosis can be made in advanced stages, which greatly reduces the likelihood of treatment and lowers the survival rate. For the treatment of epithelial ovarian cancers, the search for synthetic agents as well as agents of natural origin continues. The effects of 1-(2-cyanobenzyl)-3-(4-vinylbenzyl)-1H-benzo[d]imidazole-3-ium chloride (BD), a benzimidazole derivative, were investigated on epithelial ovarian cancer cells. METHODS AND RESULTS: In our study, the effects of BD on proliferation, colony formation, cell death by apoptosis and the cell cycle in A2780 and A2780 Adriamycin (ADR) ovarian cancer cell lines were investigated. Proliferation was examined with cell viability analysis, colony formation and apoptosis with Annexin V staining and cell cycle analyses with PI staining, respectively. As a result of the analyses, BD inhibited cell proliferation and colony formation, induced apoptosis and cell death at 48 h in A2780 and A2780 ADR cells at 10.10 and 10.36 µM concentrations, respectively. In addition, A2780 and A2780ADR cells were arrested in the Sub-G1 phase of the cell cycle. CONCLUSIONS: BD suppresses cancer cell progression by showing antiproliferative effects on ovarian cancer cells. Further analyses are required to determine the mechanism of action of this agent and to demonstrate its potential as a suitable candidate for the treatment of epithelial ovarian cancer.

PURPOSE: The effectiveness of the Colorectal Cancer (CRC) screening program is assessed based on the reduction in CRC mortality and incidence rates over time. To accurately estimate the long-term impact, it is advisable to monitor additional indicators such as age and stage-specific incidence rates. Our objective is to evaluate the effectiveness of the National CRC Screening Program in Turkey and analyze its influence on disease stage at diagnosis and survival rates. METHODS: The National CRC Screening Program was considered an intervention and the distribution of local, regional, and distant diseases, and survival estimates were assessed before and after the intervention to evaluate the effectiveness of the intervention. RESULTS: 518 patients were included in the study. At the time of diagnosis, localized, regional, and distant disease in pre-intervention were 31.3%, 42.9%, 25.8%, while post-intervention were 42.8%, 33.3%, 23.9%, respectively (p = 0.020). The relative effectiveness of the intervention in males, females, and 50-70 ages were calculated as 1.2[95% CI 0.95-1.73], 1.5[95% CI 1.04-2.18], and 1.6[95% CI 1.21-2.28] in localized disease, 0.8[95% CI 0.67-1.18], 0.6[95% CI 0.43-0.90], and 0.6[95% CI 0.46-0.81] in regional diseases, 0.8[95% CI 0.57-1.20], 1.1[95% CI 0.66-1.84], and 1.0[95% CI 0.70-1.57] in distant disease, respectively. CONCLUSION: A noticeable shift in the disease stage at the time of diagnosis was observed; however, this shift varied among gender and age groups. To effectively evaluate the impact of a cancer screening program on reducing the incidence and mortality rates of the disease, it is essential to monitor and analyze these indicators alongside 5-10-year survival estimates and stage changes at the time of diagnosis.

The anti-inflammatory and immunosuppressive drugs which are used in the treatment of Graft-versus-Host Disease (GVHD) have limited effects in controlling the severity of the disease. In this study, we aimed to investigate the prophylactic effect of Alantolactone (ALT) in a murine model of experimental GVHD. The study included 4 BALB/c groups as hosts: Naïve (n = 7), Control GVHD (n = 16), ALT-GVHD (n = 16), and Syngeneic transplantation (n = 10). Busulfan (20 mg/kg/day) for 4 days followed by cyclophosphamide (100 mg/kg/day) were administered for conditioning. Allogeneic transplantation was performed with cells collected from mismatched female C57BL/6, and GVHD development was monitored by histological and flow cytometric assays. Additionally, liver biopsies were taken from GVHD patient volunteers between ages 2-18 (n = 4) and non-GVHD patients between ages 2-50 (n = 5) and cultured ex vivo with ALT, and the supernatants were used for ELISA. ALT significantly ameliorated histopathological scores of the GVHD and improved GVHD clinical scores. CD8+ T cells were shown to be reduced after ALT treatment. More importantly, ALT treatment skewed T cells to a more naïve phenotype (CD62L+ CD44-). ALT did not alter Treg cell number or frequency. ALT treatment appears to suppress myeloid cell lineage (CD11c+). Consistent with reduced myeloid lineage, liver and small intestine levels of GM-CSF were reduced in ALT-treated mice. IL-6 gene expression was significantly reduced in the intestinal tissue. Ex vivo ALT-treated liver biopsy samples from GVHD patients showed a trend of decrease in pro-inflammatory cytokines but there was no statistical significance. Collectively, the data indicated that ALT may have immunomodulatory actions in a preclinical murine GVHD model.

Introduction: Systemic inflammation resulting from comorbidities such as arterial hypertension, diabetes, and obesity is responsible for the pathogenesis of myocardial structural and functional changes in heart failure. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are novel biomarkers of inflammation. The aim of this study was to evaluate the relationship between blood NLR and PLR levels and one-year cardiac mortality in primary prevention patients with left ventricular ejection fraction (LVEF) ≤35%, using an intracardiac defibrillator. METHODS: A total of 180 compensated heart failure patients with LVEF<35% (ischemic or nonischemic) and implantable cardioverter-defibrillator (ICD) therapy for primary prevention who applied to the cardiology outpatient clinic of Zonguldak Bülent Ecevit Üniversitesi Hospital, Zonguldak, Türkiye, between March 2018 and June 2019 were consecutively included. The patients were followed for one year after the application. RESULTS: In the multivariate logistic regression analysis model, only NLR (OR: 1.328; 95%CI: 1.129-1.563; p <0.01) was found independently associated with the risk of one-year cardiovascular mortality. Based on the NLR, levels were 2.69 ng/ml, and the area under the curve was found to be 0.795 (95%CI: 0.729-0.862) in the evaluation made with the receiver operating characteristic curve. CONCLUSION: High NLR ratio levels independently predicted one-year cardiac mortality in patients with LVEF<35% and ICD for secondary protection. Large-scale randomized studies are needed to fully demonstrate the relationship between NLR levels and cardiovascular mortality in patients with severe left ventricular dysfunction and ICD.
RESUMO
Health literacy is an important determinant of health care use among refugees and migrant communities. This present study aimed to evaluate the relationship between health literacy levels, sociodemographic characteristics, and the status of receiving the COVID-19 vaccine in Syrians under "Temporary Protection" in Istanbul. This study was conducted in February, March, and May 2022 in an Extended Migrant Health Center in Istanbul, with a survey prepared in Arabic under observation. A total of 571 questionnaires were analyzed. The mean age of the participants was 31.92 ± 6.14, and 80.7% were female and 26.6% were high school graduates. A total of 55.0% of Syrians have not had any of the COVID-19 vaccines. The health literacy level of 1.1% of the immigrants was determined as "excellent", 68.7% as "inadequate", 20.7% as "problematic/limited", and 9.6% as "adequate". According to the logistic regression model, being male, of elder age, middle and above economic status, and having a chronic disease in the family were determined as the variables associated with the status of being vaccinated against COVID-19. Refugees are a group often exposed to inequalities in access to health services. Increasing health literacy in these groups will provide a significant improvement in access to and use of health services.
RESUMO
INTRODUCTION: Diabetes mellitus is one of the major risk factors for coronary artery disease. Intravascular ultrasound (IVUS) imaging has an important role in the evaluation of atherosclerotic coronary artery disease. The aim of the study was to investigate the potential link between diabetes mellitus and plaque vulnerability in patients with coronary artery disease. METHODS: In total, 26 patients with acute coronary syndrome (eight with diabetes mellitus) and 34 with stable angina pectoris (16 with diabetes mellitus) constituted the study population. Patients underwent IVUS ultrasound and virtual histology (VH)-IVUS imaging during routine diagnostic catheterization procedures. A total of 70 plaques in 60 patients were examined. RESULTS: Patients with diabetes mellitus had a significantly greater percentage of fibrofatty components in the minimal lumen area (MLA) (17 ± 12 in diabetics; 12 ± 6 in non-diabetics; p=0.06). Thin-cap fibroatheromas were more frequent in patients with diabetes mellitus (72% versus 45%; p=0.012). There was a positive correlation between the presence of attenuated plaque and hemoglobin A1C (HbA1c) levels as well (7.09 ± 1.66 versus 6.02 ± 1.00; p=0.011). Patients with HbA1C ≥7.5% also had the highest prevalence of attenuated plaque. CONCLUSION: As shown by VH-IVUS, the prevalence of vulnerable plaques in patients with diabetes mellitus was much higher than that in non-diabetic patients. The presence of attenuated plaque detected in grayscale intravascular ultrasonography was associated with high HbA1C levels in diabetic patients. Diabetes mellitus may cause cardiovascular vulnerability by changing the plaque morphology.
RESUMO
BACKGROUND: Heart failure with preserved ejection fraction is a complex and heterogeneous clinical syndrome, poses significant diagnostic challenges. The HFA-PEFF [Heart Failure Association of ESC diagnostic algorithm, P (Pretest Assessment), E (Echocardiographic and Natriuretic Peptide score), F1 (Functional testing in Case of Uncertainty), F2 (Final Aetiology)] and H2FPEF [Heavy (BMI>30 kg/m2), Hypertensive (use of ≥2 antihypertensive medications), atrial Fibrillation (paroxysmal or persistent), Pulmonary hypertension (Doppler Echocardiographic estimated Pulmonary Artery Systolic Pressure >35 mm Hg), Elderly (age >60 years), Filling pressure (Doppler Echocardiographic E/e' >9)] scoring systems were developed to aid in diagnosing heart failure with preserved ejection fraction. This study aimed to assess the concordance and clinical accuracy of these scoring systems in the 'A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON' cohort. METHODS: A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON study was conducted as a multicenter, cross-sectional, and observational study; to evaluate a group of Heart failure with mildly reduced ejection fraction and heart failure with preserved ejection fraction patients who were seen by cardiologists in 13 participating centers across 12 cities in Türkiye. RESULTS: The study enrolled 819 patients with heart failure with preserved ejection fraction, with high probability heart failure with preserved ejection fraction rates of 40% and 26% for HFA-PEFF and H2FPEF scorings, respectively. The concordance between the 2 scoring systems was found to be low (Kendall's taub correlation coefficient of 0.242, P < .001). The diagnostic performance of both scoring systems was evaluated, revealing differences in their approach and ability to accurately identify heart failure with preserved ejection fraction patients. CONCLUSION: The low concordance between the HFA-PEFF and H2FPEF scoring systems underscores the ongoing challenge of accurately diagnosing and managing patients with heart failure with preserved ejection fraction. Clinicians should be aware of the strengths and limitations of each scoring system and use them in conjunction with other clinical and laboratory findings to arrive at an accurate diagnosis. Future research should focus on identifying additional diagnostic factors, developing more accurate and comprehensive diagnostic algorithms, and investigating alternative methods of diagnosis or stratification of patients based on different clinical characteristics.

The frequency of using tobacco products every day, the daily number of cigarettes smoked, and the frequency of exposure to tobacco products in closed areas were higher among men.
RESUMO
There are conflicting reports not only on the effect of scientific inquiry on academic achievement but also insufficient evidence on the relationship between understanding the nature of scientific inquiry and academic achievement; more generalizable studies are needed. The purpose of this large sampled study was to investigate the middle school graduates' understandings of scientific inquiry (SI) and the relationship between students' understandings of SI and academic achievement. The sample of the study (X = 3067) was selected by purposeful and layered-sampling techniques among ninth grade students studying at high schools with different orientations in Istanbul. Descriptive and inferential statistical approaches were used in the data analysis procedure. The students' academic achievement was operationally defined as the scores they received in the High School Entrance Exam (HEE). Views about scientific inquiry scale was applied to determine the participants' understandings about scientific inquiry. The data were collected in the first 2 weeks of the first semester of high school in accordance with the purpose of the study. The results of the study revealed that middle school graduates generally do not have adequate understandings of SI. Furthermore, according to the findings except for the "conclusion data conformity" aspect, there are statistically significant correlations between students' academic achievement and understandings in all aspects of SI.
RESUMO
Infectious diseases pose a major threat to elderly populations. Streptococcus pneumonia bacteria, influenza-causing viruses, and COVID-19 viruses cause three pathologies in the respiratory system with similar symptoms, transmission routes, and risk factors. Our study aimed to evaluate the effects of pneumococcal, influenza, and COVID-19 vaccinations on the status of COVID-19 hospitalization and progression in people over 65 years of age living in nursing homes. This study was performed in all nursing homes and elderly care centers in the Uskudar district of Istanbul.The diagnosis rate of COVID-19 was determined as 49%, the rate of hospitalization as 22.4%, the rate of hospitalization in the intensive care unit as 12.2%. The rate of intubation was determined as 10.4%, the rate of mechanical ventilation as 11.1% and the rate of COVID-19 related mortality rate as 9.7%. When the factors affecting the diagnosis of COVID-19 were examined, the presence and dose of COVID-19 vaccine was protective. When the factors affecting hospitalization status were examined, male sex and presence of chronic disease were risk factors; four doses of COVID-19 vaccine and influenza vaccine and pneumococcal vaccine together with COVID-19 vaccine were protective. When the factors affecting COVID-19-related death were examined, the male sex was a risk factor; the pneumococcal and influenza vaccine together with COVID-19 vaccine were protective. Our results revealed that the availability of influenza and pneumococcal vaccines positively impacted the progression of COVID-19 disease in the elderly population living in nursing homes.
RESUMO
Background: Although preventive health practices are extremely effective in preventing diseases and mortality, there is still a need to determine the frequency of these practices in different countries and improve these rates. The aim of this study was to evaluate preventive health practices in Turkey. Methods: The study was designed as a cross-sectional research. The study was conducted by utilizing the "Turkey Health Survey 2019" microdata set from the Turkish Statistical Institute. The data of 17,084 people aged 15 years and over were evaluated. Results: Approximately 54.4% of the participants were women, 24.5% were 15-29 years old, and 21.0% were 60 years of age or older. Approximately 51.2% of the participants stated that their general health status as good. 2.3% of the participants had taken the flu vaccine in the last year, 38% of people aged 50-70 years had undergone a fecal occult blood test in the last 5 years, 32% of women aged 40-69 years had undergone mammography/breast X-ray in the last 2 years, and 44% of women aged 30-65 years had undergone a cervical swab test in the last 5 years. Conclusion: Although the rate of public participation in cancer screenings in Turkey is considerable, the data show that the rates should be further increased. In contrast, flu vaccination frequency is considerably low. To increase the frequency of preventive health practices, Turkish public should be informed about these practices, where they can be performed, and their importance.
RESUMO
Diseases are quite common in fish farms because of changes in physico-chemical characteristics in the aquatic environment, and operational concerns, i.e., overstocking and feeding issues. In the present study, potential factors (water physico-chemical characteristics and heavy metal load) on the disease-causing state of the pathogenic bacteria Lactococcus garvieae and Vagococcus sp. were examined with machine learning techniques in a trout farm. Recording of physico-chemical characteristics of the water, fish sampling and bacteria identification were carried out at bimonthly intervals. A dataset was generated from the physico-chemical characteristics of the water and the occurrence of bacteria in the trout samples. The eXtreme Gradient Boosting (XGBoost) algorithm was used to determine the most important independent variables within the generated dataset. The most important seven features affecting bacteria occurrence were determined. The model creation process continued with these seven features. Three well-known machine learning techniques (Support Vector Machine, Logistic Regression and Naïve Bayes) were used to model the dataset. Consequently, all the three models have produced comparable results, and Support Vector Machine (93.3% accuracy) had the highest accuracy. Monitoring changes in the aquaculture environment and detecting situations causing significant losses through machine learning techniques have a great potential to support sustainable production.
RESUMO
BACKGROUND: Gaucher disease (GD) is the most common autosomal recessive lipid storage disease. In this study, the changes in TFH cells and IL-4 and IL-21 cytokines in blood samples of GD patients, carriers and healthy volunteers were investigated. METHODS: Two pretreatment type 1 GD patients, 20 currently treated type 1 GD patients, 6 carriers, and 27 healthy volunteers were enrolled in the study. TFH cell (CD45RA-CD4+CXCR5+) number, phenotype (PD1, ICOS expression), and cytokine production (IL-21, IL-4) were assessed via flow cytometric assays. RESULTS: No significant differences were found between the groups with respect to the number, frequency and PD1 or ICOS expression of TFH cells between healthy controls, patients and carriers. However, IL-4+ TFH cells were significantly reduced both in percent and number in the treated GD patients compared with healthy controls (p < 0.05). Interestingly, the IL-21+ TFH cell number was increased in treated GD patients. When TFH cells were examined based on CXCR3 expression, the frequency of the PD1+Th17-Th2-like fraction (CXCR3-) was found to be significantly increased in treated GD patients. CONCLUSION: To our knowledge, this is the first study to assess TFH cells in GD patients, and to show that the production of IL-4 and IL-21 by TFH cells and their subsets may be altered in type 1 GD patients.

BACKGROUND AND AIMS: Gaucher disease (GD) is caused by a genetic deficiency of the beta-glucocerebrosidase enzyme which results in the accumulation of glucosylceramide in macrophages. This accumulation may induce oxidative stress, resulting in DNA damage in patients with GD. The aim of this study was to assess plasma 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels and cytokinesis-block micronucleus cytome (CBMN-cyt) assay parameters in the peripheral blood lymphocytes of patients with GD and carriers, evaluate the possible associations of these values with GD, and determine whether they can be used as potential biomarkers in GD. METHODS: This study included 20 patients with type 1 GD, six carriers, and 27 age- and sex-matched healthy controls. CBMN-cyt assay parameters in peripheral blood lymphocytes of the patients with GD, carriers, and controls were evaluated and 8-OHdG levels in their plasma samples were measured. RESULTS: CBMN-cyt assay parameters in patients with GD and carriers were not significantly different when compared with controls (p > 0.05). However, plasma 8-OHdG levels were found to be higher in both patients with GD and carriers than in control subjects (p < 0.01). CONCLUSIONS: Oxidative DNA damage may be a useful prognostic tool, whereas the CBMN-cyt assay cannot be used as a predictive biomarker of GD.

OBJECTIVE: Our objective was to evaluate cyclophilin levels in patients with acute coronary syndrome (ACS) and their association with the clinical characteristics of these patients. METHODS: We enrolled 150 patients with ACS (n=75 ST-elevation myocardial infarction [STEMI], n = 75 non-ST-elevation myocardial infarction [NSTEMI]). For comparison, 25 healthy volunteers were included in the study. Levels of cyclophilin A, cyclophilin D, and C-reactive protein (CRP) were measured in both the acute myocardial infarction (AMI) groups and the healthy group. We examined the effects of cardiovascular risk factors, including diabetes mellitus, hypertension, dyslipidemia, age, gender, and smoking on these parameters. RESULTS: Cyclophilin A levels were significantly lower in the STEMI group, while cyclophilin D and CRP levels were significantly higher in all AMI groups (P < 0.05). A negative correlation existed between cyclophilin A and troponin T and CK-MB (respectively r = -0.287, P < 0.001; r = -0.231, P = 0.005). However, there was no correlation between cyclophilin D and the cardiac markers. A positive correlation was observed between cyclophilin D and CRP (r = 0.219, P = 0.004). Cyclophilin A was associated with hypertension, whereas cyclophilin D was associated with the female gender and dyslipidemia (P < 0.05). CONCLUSION: Our findings suggest that a decrease in cyclophilin A indicates a more severe disease in STEMI and an increase in cyclophilin D in both STEMI and NSTEMI may be valuable markers. Therefore, further detailed studies are warranted to monitor their changes and interactions in ACS patients.

Objective: To reveal the correlation between implantation age, the internal acoustic canal (IAC) width, bony cochlear nerve canal (BCNC) width, and auditory performance in primary school children with bilateral cochlear implantation (CI). Methods: Preoperative IAC and BCNC widths of 57 pre-lingually deaf children aged 7-11 years who had previously undergone bilateral CI in our institution were reviewed and cut-off values were calculated. Twenty-four patients who had additional problems and could not attend school and those who refused to participate in the study were excluded. The remaining 33 were invited to the hospital, and their speech perception tests, and language development scores were analyzed (16 of 33 patients had been operated on before the age of 24 months). Results: The cut-off values calculated from the 114 ears of 57 patients were 3.86 mm for IAC width and 1.56 mm for BCNC width. The auditory performances of the 33 patients after CI were not significantly different in the narrow and normal width groups. However, speech perception test results, and language development scores of patients implanted before the age of 24 months were significantly higher. Conclusion: There are some studies showing that children with bilateral sensorineural hearing loss have narrower IAC and BCNC widths. However, we concluded that the widths of the IAC and the bone cochlear nerve canal did not affect auditory performance. We found that implantation age is the single most important determinant of speech-language development after CI.
RESUMO
OBJECTIVE: This study aims to evaluate the patient clinics by studying Variant of Concern (VOC) Polymerase Chain Reaction (PCR) on conventional PCR-positive samples in a training and research hospital COVID test center in Istanbul. METHODS: The study is a descriptive type and VOC PCR from all samples (from a total of 1300 samples) which detected positive by conventional PCR in a training and research hospital COVID test center between February 2 and 9, 2021. The United Kingdom mutation (VOC 202012/01, B.1.1.7) has been studied. Clinics parameters of the patients were evaluated from Public Health Management System (HSYS) records. The statistical significance was taken as p<0.05 in the analysis. RESULTS: Within the scope of the research, 1300 PCR-positive COVID-19 patients were evaluated. VOC mutation was positive in 26.1% of all patients (339 persons), and 5.8% of patients (75 persons) were hospitalized. While 3.2% (11 persons) of those with VOC positivity were hospitalized, 6.7% (64 persons) of VOC negatives were hospitalized (p=0.020). About 18.2% of hospitalized VOC positives (two persons) and 23.4% of VOC negatives (15 persons) are in intensive care. CONCLUSION: When VOC mutation was examined in all admitted and hospitalized patients, it was detected that VOC mutation was less frequent in hospitalized patients. No relationship between hospitalization and intensive care stay and VOC mutation was detected. It is recommended to determine with studies the contagiousness of patients with VOC mutations.
