Which aerobic exercise is more effective in Parkinson's patients? Cycle ergometer versus body weight-supported treadmill.

Objectives: The study aimed to evaluate the effects of aerobic exercise applied with bodyweight-supported treadmill (BWSTT) or cycle ergometer (CE) in Parkinson's patients. Patients and methods: In the prospective single-blind study, 38 Parkinson's patients with Hoehn-Yahr Stage 1-3 were randomized into the CE and BWSTT groups between May 2019 and March 2020. Evaluations before and after six weeks of treatment included a six-min walking test with a software device as the primary outcome and functional balance tests (Tinetti balance and gait test, one-leg stance balance test) as secondary outcomes. Both groups received 40 min of aerobic exercise three days per week with conventional rehabilitation and various methods. CE and BWSTT groups were created. The aerobic exercise program was designed based on treatment recommendations for Parkinson's patients of the American College of Sports Medicine (CE test, with the Karvonen formula, 40-60% reserve). Posttreatment and pretreatment evaluations were compared within and between groups. Results: The six-week aerobic exercise program was completed by 16 participants (9 males, 7 females; mean age: 65.9±8.1; range, 47 to 78 years) in the CE group and 15 participants (9 males, 6 females; mean age: 62.5±7.5; range, 49 to 79 years) in the BWSTT group. The demographic characteristics of the patients were similar. Primary and secondary outcomes were significantly different after treatment than before treatment in both groups. There were no significant differences between the groups in outcomes. Conclusion: The results showed that both methods are effective and not superior to each other. Aerobic exercise programs led by experienced clinicians can benefit patients.

Retrospective evaluation of the contribution of radiotherapy to survival in breast cancer treatment with propensity score based on stage and subgroup.

BACKGROUND: Breast cancer has been a disease in which treatment strategy has changed over time under the influence of different hypotheses and evidence for more than a century. We analyzed the contribution of radiotherapy to disease-free survival and overall survival by classifying according to stage, 1-3 lymph node involvement, and molecular subgroups. METHODS: Following the approval of the Institutional Review Board, records of patients with breast cancer who were admitted to University School of Medicine Departments of Radiation Oncology and Medical Oncology between July 1999 and December 2020 were reviewed. Using data propensity score matching was performed between the groups that did and did not receive radiotherapy using an optimal matching algorithm (optimum, 1:1). Disease-free survival and overall survival after propensity score matching were calculated using the Kaplan-Meier method. Univariate and multivariate Cox regression analysis was used to estimate hazard ratios. RESULTS: In the radiotherapy and non-radiotherapy groups, disease-free survival was 257.42 ± 5.46 (246.72- 268.13), 208,96 ± 8,15 (192,97-224,94) months respectively, (p = < 0.001), overall survival was 272,46 ± 8,68 (255,43-289,49), 219,05 ± 7,32 (204,70-233,41) months respectively (p = .002). We compared the 19 N1 patient groups who received radiotherapy with the 19 patients who did not receive radiotherapy and calculated the disease-free survival times was 202,21 ± 10,50 (181,62-222,79) and 148,82 ± 24,91 (99,99-197,65) months respectively (p = .011) and overall survival times was 200,85 ± 12,79 (175,77-225,92) and 166,90 ± 20,39 (126,93-206,82) months respectively (p = .055). We examined disease-free survival and overall survival times in both groups according to Luminal A, Luminal B, TNBC, and HER2-enriched subgroups. In the Luminal B subgroup, the disease-free survival duration in the groups receiving radiotherapy and not receiving radiotherapy was 264.83 ± 4.95 (255.13-274.54) and 187.09 ± 11.06 (165.41-208.78) months (p < .001), and overall survival times were 252.29 ± 10.54 (231.62-272.97) and 197.74 ± 9.72 (178.69-216.80) months (p = .001) respectively. CONCLUSIONS: Thanks to studies proving that RT increases long-term survival rates in breast cancer as a result of reducing locoregional recurrence and systemic metastasis rates, it has been understood that the spectrum hypothesis is the hypothesis that most accurately describes breast cancer to date. We found that patients with Luminal B invasive breast cancer benefited significantly more from RT compared to other subgroups.

The importance of speckle tracking echocardiography in the evaluation of cardiac functions in patients with rheumatoid arthritis.

Objectives: In this study, we aimed to analyze the layer-specific strain values obtained by speckle tracking echocardiography (STE) method in the determination of subclinical cardiac dysfunction in rheumatoid arthritis (RA) patients. Patients and methods: Between February 2019 and October 2019, a total of 63 female RA patients (mean age: 51.82±6.07 years; range, 40 and 65 years) who had a confirmed diagnosis were included. Thirty-one age-matched female healthy individuals (mean age: 50.71±5.37 years; range, 40 and 65 years) were selected as the control group. The patients were divided into three groups according to the duration of disease as <5 years, 5-10 years and >10 years. The Disease Activity Score in 28 joint - C-reactive protein (CRP) was used to determine disease activation. The standard assessment included complete serum CRP, anti-cyclic citrullinated peptide, rheumatoid factor, N-terminal pro B-type natriuretic peptide (NT-proBNP), and homocysteine. Global longitudinal strain (GLS) analysis was performed with STE. Results: The NT-proBNP values were found to be higher in RA patients compared to the control group (p=0.044). In terms of conventional echocardiographic parameters, a significant difference between E/A and E/E' ratios was observed (p<0.001 and p=0.015). Endocardium, transmural, and epicardium GLS values obtained by STE were found to be lower in RA patients (p<0.05). The left ventricular (LV) GLS values worsened, as the duration of disease increased (p<0.05). There was a significant correlation between RA disease activity and LV GLS values, showing that increasing levels of disease activity was associated with worse LV GLS (r=0.583, p<0.01 and r=0.681, p<0.01 and r=0.689, p<0.01 for endocardium, transmural and epicardium, respectively). Conclusion: Our study results suggest that the layer-specific GLS values obtained by STE decrease in RA patients.

The Impact of Total Tumor Diameter on Lymph Node Metastasis and Tumor Recurrence in Papillary Thyroid Carcinomas.

(1) Introduction: The impact of multifocality/bilaterality on the prognosis of papillary thyroid carcinoma (PTC) is a matter of debate. In order to clarify this debate, several studies have attempted to identify additional parameters associated with poor prognosis, including total tumor diameter (TTD), in the context of multifocal PTCs. In this context, this study was carried out to investigate the impact of TTD on tumor recurrence and lymph node metastasis (LNM) in PTCs. (2) Materials and Methods: The sample of this single-center retrospective study consisted of 706 patients diagnosed with PTC. TTD was calculated as the sum of the largest diameters of tumor foci in multifocal tumors. The resulting TTDs were grouped into TTDs ≤ 10 mm, TTDs > 10 mm, TTDs ≤ 20 mm, and TTDs > 20 mm, using 10 mm and 20 mm as cutoff values. (3) Results: There was no significant difference between multifocal papillary microcarcinomas (PTMCs) with a TTD of >10 mm and unifocal PTCs with a primary tumor diameter (PTD) of >10 mm except for advanced age and lymphovascular invasion (LVI). In addition, perineural invasion (PNI) and TTD > 10 mm were found to be significant risk factors for LNM, and PNI, TTD > 10 mm, TTD > 20 mm, and bilaterality were found to be significant risk factors for recurrence. LVI, and TTD > 10 mm were found to be independent significant predictors for recurrence, and LVI and extrathyroidal extension (ETE) were found to be independent significant predictors for LNM. (4) Conclusions: Considering TTD > 10 mm in recurrence risk categorization models and adopting a clinical approach that takes into account multifocal PTMCs with TTD > 10 mm along with unifocal PTCs with PTD > 10 mm may be more useful in terms of clinical management of the disease.

A Comprehensive Approach to the Thyroid Bethesda Category III (AUS) in the Transition Zone Between 2nd Edition and 3rd Edition of The Bethesda System for Reporting Thyroid Cytopathology: Subcategorization, Nuclear Scoring, and More.

Significant interobserver variabilities exist for Bethesda category III: atypia of undetermined significance (AUS) of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). Thus, subcategorization of AUS including AUS "nuclear" and AUS "other" is proposed in the recent 3rd edition of TBSRTC. This study investigated the impact of the nuclear features/architectural features/nuclear score (NS) (3-tiered)/subcategories and subgroups on risk of malignancy (ROM) in thyroid fine-needle aspirations (FNA). 6940 FNAs were evaluated. 1224 (17.6%) cases diagnosed as AUS were reviewed, and 240 patients (initial FNAs of 260 nodules and 240 thyroidectomies) were included. Subcategories and subgroups were defined according to TBSRTC 2nd and 3rd editions. Histological diagnostic groups included nonneoplastic disease, benign neoplasm, low-risk neoplasm, and malignant neoplasm. Overall, ROM was 30.7%. ROM was significantly higher in FNAs with nuclear overlapping (35.5%), nuclear molding (56.9%), irregular contours (42.1%), nuclear grooves (74.1%), chromatin clearing (49.4%), and chromatin margination (57.7%), and these features were independent significant predictors for malignancy. FNAs with NS3 had significantly higher ROM (64.2%). Three-dimensional groups were significantly more frequent in malignant neoplasms (35.7%). ROM was significantly higher in AUS-nuclear subcategory (48.2%) and in AUS-nuclear and architectural subcategory (38.3%). The highest ROM was detected in AUS-nuclear1 subgroup (65.2%). ROM was significantly higher in the group including AUS-nuclear and AUS-nuclear and architectural subcategories, namely "high-risk group" than the group including other subcategories, namely "low-risk group" (42.0%vs 13.9%). In conclusion, subcategorization may not be the end point, and nuclear scoring and evaluation of architectural patterns according to strict criteria may provide data for remodeling of TBSRTC categories.

Effect of Preoperative Anxiety on Depth of Anaesthesia and In Vitro Fertilization Success.

Objective: Infertility anxiety may have a harmful effect on embryo quality and fertilization during in vitro fertilization (IVF). Monitoring brain function gives real-time information about the depth of anaesthesia of a patient. This study examined the effect of preoperative anxiety on the depth of anaesthesia and IVF success. Methods: One hundred thirty-one patients who had undergone oocyte retrieval were divided into two groups according to the Beck Anxiety Inventory (BAI): the low-anxious Group L (n = 71) and high-anxious Group H (n = 60). Hemodynamic stability, intraoperative total propofol and fentanyl consumption, good quality embryo (GQE) rate, and fertilization rate were recorded. Results: Fertilization and GQE rates were not significant between groups L and H. Total propofol consumption was significantly higher in group H than in group L. Heart rate (HR) preoperatively and postoperatively and systolic arterial pressure (SAP) preoperatively and diastolic arterial pressure (DAP) postoperatively were significantly increased in group H than in group L. The time for the modified Aldrete score to reach 9 (MAS 9) in group H was significantly higher than that in group L. The effect of variables that were found significantly in the univariate analysis (Propofol, HRpreop, HRpostop, SAPpreop, DAPpostop, and MAS 9) on BAI score. Conclusion: Total propofol consumption was higher in patients with high anxiety levels, but it did not have a negative effect on IVF success.

Obsessive compulsive symptoms in mothers of children with atopic dermatitis.

Introduction: Maternal stress, depression and anxiety are associated with atopic dermatitis (AD) in offspring. However, the relationship between maternal obsessive compulsive symptoms (OCS) and AD in their children is unclear. Aim: To investigate whether maternal OCS are associated with AD in offspring. Material and methods: A total of 75 children with AD diagnosed by the paediatric allergist and 76 healthy children and their mothers were included in the study. A Turkish version of the Maudsley Obsessive Compulsive Inventory (MOCI-T) was used to assess OCS of mothers in both groups. Results: Total MOCI-T score and slowness, doubt, and rumination subscale scores were higher in the AD group than in the healthy group (p = 0.007, p = 0.001, p = 0.012 and p = 0.011, respectively) but washing/cleaning and checking subscale scores did not reach a statistically significant difference (p = 0.203 and p = 0.053, respectively). There was no correlation between SCORing Atopic Dermatitis (SCORAD) and MOCI-T/subscales scores. Conclusions: Our study provides evidence for associations between maternal OCS and infantile AD. The findings support recommendations for psychosocial support of mothers of children with AD.

Clinicopathological and molecular analyses of uterine carcinosarcomas using next-generation sequencing: A single-center experience.

Background: Uterine carcinosarcomas (UCS) constitute 3-4% of all uterine malignancies and 16% of deaths caused due to uterine neoplasms. Aim: In this study, we aimed to perform DNA-based mutation analysis in 12 genes (KRAS, NRAS, EGFR, C-KIT, BRAF, PDGFRA, ALK, ERBB2, ERBB3, ESR1, RAF1, PIK3CA) to determine the molecular subtypes of UCS using next-generation sequencing (NGS) in patients with aggressive UCS and poor prognosis. We aimed to compare the results of our analysis with clinicopathological data to contribute to the development of targeted therapy approaches related to the molecular changes of UCS. Materials and Methods: In this study, we included 12 cases diagnosed with uterine carcinosarcomas and examined the changes in oncogenes that play a role in UCS pathogenesis. For the analysis of mutation, the clinicopathological data were compared with the variations in the DNA-based gene panel consisting of 12 genes and 1237 variants in the UCS using the NGS method. Results: EGFR mutation was found in 91.7% of the cases, mutation in 41.7%, PDGFRA mutation in 25%, KRAS and PIK3CA mutation in 16.7%, and C-KIT mutation in 8.3% of the cases. Although no statistical significance was found between the detected mutation and clinicopathological data, it was concluded that PDGFRA mutation might be associated with advanced-stage disease development. Conclusion: This study's findings regarding different molecular types of UCS and information on oncogenesis of UCS can provide inferences for targeted therapies in the future by identifying targetable mutations representing early oncogenic events and thereby contribute toward further studies on this subject.

Neutrophil to Lymphocyte Ratio and Serum Biomarkers : A Potential Tool for Prediction of Clinically Relevant Cerebral Vasospasm after Aneurysmal Subarachnoid Hemorrhage.

OBJECTIVE: Subarachnoid hemorrhage (SAH) is a condition characterized by bleeding in the subarachnoid space, often resulting from the rupture of a cerebral aneurysm. Delayed cerebral ischemia caused by vasospasm is a significant cause of mortality and morbidity in SAH patients, and inflammatory markers such as systemic inflammatory response index (SIRI), systemic inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), and derived NLR (dNLR) have shown potential in predicting clinical vasospasm and outcomes in SAH patients. This article aims to investigate the relationship between inflammatory markers and cerebral vasospasm after aneurysmatic SAH (aSAH) and evaluate the predictive value of various indices, including SIRI, SII, NLR, and dNLR, in predicting clinical vasospasm. METHODS: A retrospective analysis was performed on a cohort of 96 patients who met the inclusion criteria out of a total of 139 patients admitted Trakya University Hospital with a confirmed diagnosis of aSAH between January 2013 and December 2021. Diagnostic procedures, neurological examinations, and laboratory tests were performed to assess the patients' condition. The Student's t-test compared age variables, while the chi-square test compared categorical variables between the non-vasospasm (NVS) and vasospasm (VS) groups. Receiver operating characteristic (ROC) curve analyses were used to evaluate the diagnostic accuracy of laboratory parameters, calculating the area under the ROC curve, cut-off values, sensitivity, and specificity. A significance level of p<0.05 was considered statistically significant. RESULTS: The study included 96 patients divided into two groups : NVS and VS. Various laboratory parameters, such as NLR, SII, and dNLR, were measured daily for 15 days, and statistically significant differences were found in NLR on 7 days, with specific cut-off values identified for each day. SII showed a significant difference on day 9, while dNLR had significant differences on days 2, 4, and 9. Graphs depicting the values of these markers for each day are provided. CONCLUSION: Neuroinflammatory biomarkers, when used alongside radiology and scoring scales, can aid in predicting prognosis, determining severity and treatment decisions for aSAH, and further studies with larger patient groups are needed to gain more insights.

Latency of epileptic and psychogenic nonepileptic seizures.

BACKGROUND: Due to their semiological similarities, psychogenic nonepileptic seizures (PNESs) can occasionally hardly be differentiated from epileptic seizures (ESs), and long-term video-electroencephalographic monitoring (VEM) is needed for the differential diagnosis. OBJECTIVE: To investigate the time of the first clinical event and its distribution on the days of VEM in ES and PNES patients. METHODS: In total, a consecutive series of 48 PNES and 51 ES patients matched for gender and age were retrospectively and consecutively evaluated. The time distribution of the seizures during the day was noted. Seizure latency was determined as the time in hours from the start of the video-electroencephalographic recording to the first clinical event. RESULTS: The seizure latency was significantly shorter in PNES patients compared to ES patients (p < 0.001). Seventy-two percent of PNES patients and 49.1% of ES patients had their first seizure in the 24 hours of video-EEG recording (p = 0.023). Recording longer than 48 hours was required for 12.5% of PNES patients and 37.3% of ES patients (p = 0.006). While ESs were almost evenly distributed throughout the day, most PNESs occurred during the evening hours (p = 0.011). CONCLUSION: We observed that the PNESs appeared earlier than the ESs in the VEM and were concentrated during daylight hours. Although not strictly reliable, seizure latency can contribute to the differential diagnosis of ES and PNES.

ANTECEDENTES: Debido a sus similitudes semiológicas, las crisis no epilépticas psicógenas (CNEP) en ocasiones apenas se pueden diferenciar de las crisis epilépticas (CE), y se necesita una monitorización video-electroencefalográfica (EEG) prolongada para el diagnóstico diferencial. OBJECTIVO: Investigar el momento del primer evento clínico y su distribución en los días de monitorización video-EEG en pacientes con CE y CNEP. MéTODOS: Se evaluó retrospectivamente a una serie consecutiva de 48 pacientes con CNEP y 51 con ES emparejados por sexo y edad. Se anotó la distribución temporal de las incautaciones durante el día. La latencia de las crisis se determinó como el tiempo en horas desde el inicio de la grabación del video-EEG hasta el primer evento clínico. RESULTADOS: La latencia de las crisis fue significativamente menor en los pacientes con CNEP en comparación con los pacientes con CE (p < 0,001). El 72% de los pacientes con CNEP y el 49,1% de los pacientes con CE tuvieron su primera crisis en las 24 horas de registro del video-EEG (p = 0,023). Se requirió un registro de más de 48 horas para el 12,5% de los pacientes con CNEP y el 37,3% de los pacientes con CE (p = 0,006). Mientras que las CE se distribuyeron casi uniformemente a lo largo del día, la mayoría de las CNEP ocurrieron durante las horas después del anochecer (p = 0,011). CONCLUSIóN: Observamos que las CNEPs aparecieron antes que las CEs en la monitorización video-EEG, y se agruparon durante las horas del día. Aunque no es estrictamente confiable, la latencia de las crisis puede contribuir al diagnóstico diferencial de ES y CNEP.

Classifying invasive lobular carcinoma as special type breast cancer may be reducing its treatment success: A comparison of survival among invasive lobular carcinoma, invasive ductal carcinoma, and no-lobular special type breast cancer.

PURPOSE: The literature contains different information about the prognosis of invasive lobular carcinoma of breast cancer (BC). We aimed to address the inconsistency by comparatively examining the clinical features and prognosis of invasive lobular carcinoma patients in our university and to report our experience by dividing our patients into various subgroups. PATIENTS AND METHODS: Records of patients with BC admitted to Trakya University School of Medicine Department of Oncology between July 1999 and December 2021 were reviewed. The patients were divided into three groups (No-Special Type BC, Invasive Lobular Special Type BC, No-Lobular Special Type BC). Patient characteristics, treatment methods and oncological results are presented. Survival curves were generated using the Kaplan-Meier method. Statistical significance of survival among the selected variables was compared by using the log-rank test. RESULTS: The patients in our study consisted of 2142 female and 15 male BC patients. There were 1814 patients with No-Special Type BC, 193 patients with Invasive Lobular Special Type BC, and 150 patients with No-Lobular Special Type BC. The duration of disease-free survival (DFS) was 226.5 months for the No-Special Type BC group, 216.7 months for the No-Lobular Special Type BC group, and 197.2 months for the Invasive Lobular Special Type BC group, whereas the duration of overall survival (OS) was 233.2 months for the No-Special Type BC group, 227.9 for the No-Lobular Special Type BC group, and 209.8 for the Invasive Lobular Special Type BC group. The duration of both DFS and OS was the lowest in the Invasive Lobular Special Type BC group. Multivariate factors that were significant risk factors for OS were Invasive Lobular Special Type BC histopathology (p = .045), T stage, N stage, stage, skin infiltration, positive surgical margins, high histological grade, and mitotic index. Modified radical mastectomy, chemotherapy, radiotherapy and use of tamoxifen and aromatase inhibitors for more than 5 years were significant protective factors for overall survival. CONCLUSION: The histopathological subgroup with the worst prognosis in our study was Invasive Lobular Special Type BC. Duration of DFS and OS were significantly shorter in Invasive Lobular Special Type BC than No-Lobular Special Type BC group. The classification of Invasive Lobular BC under the title of Special Type BC should be reconsidered and a more accurate treatment and follow-up process may be required.

The effects of angiotensinogen M235T/T174M and angiotensin type 1 receptor a1166c gene polymorphisms on the development of diabetic nephropathy in type 2 diabetes mellitus patients.

AIMS: Diabetic nephropathy is one of the major complications of Type 2 diabetes mellitus. In this study, we aimed to investigate the effects of angiotensinogen M235T/T174M and angiotensin type 1 receptor A1166C gene polymorphisms on the development of diabetic nephropathy in patients with type 2 diabetes mellitus. METHODS: This study included 100 type­2 diabetes mellitus patients with diabetic nephropathy patients (patient group) and 99 type­2 diabetes mellitus patients without diabetic nephropathy (control group). Polymerase chain reaction and restriction fragment length polymorphism methods were used to identify polymorphisms in the angiotensinogen M235T/T174M and angiotensin type 1 receptor A1166C genes. RESULTS: There was no significant difference in genotype frequencies of M235T gene polymorphism between patient and control groups (χ2 = 4.01, df = 2, p = 0.13). There was no significant difference in genotype frequencies of T174M gene polymorphism between patient and control groups (X2 = 0.36, df = 2, p = 0.83). There was no significant difference in genotype frequencies of A1166C gene polymorphism between patient and control groups (χ2 = 0.51, df = 2, p = 0.77). CONCLUSIONS: The results showed no significant difference in angiotensinogen M235T/T174M and angiotensin type 1 receptor A1166C gene polymorphisms between the patient and control groups. Future studies are needed to validate the results of this study and to explore underlying mechanisms (Tab. 3, Fig. 3, Ref. 35).

The Effect of Cerebral Oxygen Saturation Changes on Early Postoperative Neuropsychological Function in Patients Undergoing Cranial Surgery.

AIM: To compare the incidence of postoperative neuropsychological dysfunction in patients managed with cerebral saturation monitoring versus traditional approaches. MATERIAL AND METHODS: A hundred patients undergoing elective intracranial surgery were divided into two groups to receive intraoperative management via cerebral saturation monitoring (Group O) or the conventional approach (Group C). The postoperative neuropsychological function was evaluated by the antisaccadic eye movement test (ASEM) and the Mini-Mental State Examination (MMSE). These tests were performed preoperatively and postoperatively on the first, second, and fifth days. The time for the modified Aldrete score to reach 9 (MAS 9), adverse effects, and pain using a Visual Analog Scale (VAS) scores were recorded. RESULTS: Patient characteristics and surgery data were not statistically different. The MAS 9 of group O was significantly lower than that of group C (p < 0.001). The MMSE at the postoperative 1, 2, and 5 days were significantly higher in Group O compared to Group C (p < 0.001). ASEM was similar between groups. Group O was subdivided according to the type of surgery applied with diagnosis, and there were no statistically significant between-group differences in terms of areas under the curve for the cerebral regional oxygen saturation. There was no between-group difference regarding the mean arterial pressure at any time perioperatively. The heart rate at 80, 90, 100, and 110 min intraoperatively was significantly higher in group C than in Group O. CONCLUSION: Intraoperative cerebral oxygenation monitoring can reduce patient mortality and morbidity by allowing early postoperative neurological evaluation to detect potential neurocognitive deficits.

Investigation of Relationship Between Small Noncoding RNA (sncRNA) Expression Levels and Serum Iron, Copper, and Zinc Levels in Clinical Diagnosed Multiple Sclerosis Patients.

In our study, we aimed to investigate the relationship between microRNA (miRNA) expression levels and serum iron (Fe), copper (Cu), and zinc (Zn) levels in Multiple sclerosis (MS) patients. Total RNA was isolated from peripheral venous blood containing ethylenediaminetetraacetic acid (EDTA) of MS patients and controls. Total RNA was labeled with Cy3-CTP fluorescent dye. Hybridization of samples was performed on microarray slides and arrays were scanned. Data argument and bioinformatics analysis were performed. Atomic absorption spectrophotometer method was used to measure serum Fe, Cu, and Zn levels. In our study, in bioinformatics analysis, although differently expressed miRNAs were not detected between 16 MS patients and 16 controls, hsa-miR-744-5p upregulation was detected between 4 MS patients and 4 controls. This may be stem from the patient group consisting of MS patients who have never had an attack for 1 year. Serum iron levels were detected significantly higher in the 16 MS patients compared to the 16 controls. This may be stem from the increase in iron accumulation based on inflammation in MS disease. According to the findings in our study, hsa-miR-744-5p upregulation has been determined as an early diagnostic biomarker for the development together of insulin resistance, diabetes mellitus associated with insulin signaling, and Alzheimer's diseases. Therefore, hsa-miR-744-5p is recommended as an important biomarker for the development together of diabetes mellitus, Alzheimer's disease, and MS disease. In addition, increased serum Fe levels may be suggested as an important biomarker for neurodegenerative diseases such as Parkinson's disease, Alzheimer's disease, and MS disease.

Is music the food of the anesthesia in children?

Background: The noise in an operating room may have a detrimental effect on human cognitive functions, and it may cause perioperative anxiety with prolonged exposure. The aim of this study was to investigate the effects of music therapy and use of earplugs and normal noise level in the operating room under general anesthesia of pediatric patients on hemodynamic parameters and postoperative emergence delirium. Methods: One hundred and five pediatric patients were involved in this study. The patients were randomly divided into three groups. Group N was exposed to the ambient operating room noise, group S received earplugs from an independent anesthesiologist, and group M used a CD player. The preoperative anxiety levels of children were evaluated with the Modified Yale Preoperative Anxiety Scale (M-YPAS). Mean arterial pressure (MAP) and heart rate were recorded at 30-minute periods until the completion of surgery, end of surgery and postoperatively. During each measurement, noise level recordings were performed using sonometer. Pediatric Anesthesia Emergency Delirium (PAED) score was evaluated after postoperative extubation. Results: M-YPAS was similar between groups. The MAP at 30 and 60 min intraoperatively, at end of surgery, and at 5, 10, and 15 min postoperatively was significantly lower in group S than in group N. There were no differences in heart rate among the groups. Postoperative PAED score was not significantly different among the groups. Conclusions: The music therapy was not more effective than silence and operating noise room in reducing PAED score postoperatively in pediatric patients. Trial registration number: ClinicalTrials.gov Registry (NCT03544502).

The roles of MTHFR (C677T, A1298C) and MGP (G-7A, T-138C) gene variations in development of diabetic nephropathy in patients with type 2 diabetes mellitus.

Background: The goal of this study is to determine the role of MTHFR (C677T, A1298C) and MGP (G-7A, T-138C) gene variations in DN development. Methods: There were 61 DN patients and 55 healthy controls in this study. The genotype distributions of these gene variations were determined using PCR and RFLP methods. Results: According to our study, there was no significant relationship between these gene variations and DN (p > 0.05). The allele frequencies of the MTHFR C677T gene variation in the control group were found significantly different from the Hardy-Weinberg distribution (p < 0.05). According to combined genotype analysis, GA-TT combined genotype of MGP (G-7A/T-138C) gene variations was observed significantly more in the patient group with DN. The GA-TT combined genotype of MGP (G-7A/T-138C) gene variations was differ significantly between these groups (OR: 2.359, %95 CI: 1.094-5.087, p = 0.028). Conclusion: In our study, although MTHFR and MGP gene variations were not risk factors, the GA-TT combined genotype of the MGP (G-7A/T-138C) gene variation was detected as an important risk factor for DN.

Breast Cancer Subtypes and Prognosis: Answers to Subgroup Classification Questions, Identifying the Worst Subgroup in Our Single-Center Series.

Purpose: Many studies report the triple negative breast cancer (TNBC) as the worst subgroup, as such patients do not benefit from anti-hormonal therapy and human epidermal growth factor receptor 2 (HER2) antagonists. While HER2 overexpression was a poor prognostic factor in breast cancer before trastuzumab (Herceptin) was available, TNBC is often reported as the worst BC subgroup since targeted therapy is currently not possible. Since the patience-specific experiences and the current literature did not always align, we aimed to determine the BC subgroup with the shortest survival in our center. Methods: The records of patients with BC who were admitted to Trakya University Faculty of Medicine Department of Medical and Radiation Oncology between July 1999 and December 2019 were reviewed. Patients were divided into four main groups (Luminal A, Luminal B, TNBC, and HER2-enriched) according to the St Gallen International Consensus Panel and four subgroups in accordance with estrogen receptor, progestin receptor and HER2 positivity. Patient characteristics, treatment characteristics and clinical outcomes of the four main subgroups were evaluated. Survival curves were generated using the Kaplan-Meier method, and the significance of survival differences among the selected variables was compared by using the Log rank test. Factors affecting disease-free survival (DFS) and overall survival (OS) were analyzed by Cox regression analysis. Results: Statistical analysis was performed on 2017 patients, after excluding patients with phyllodes tumor, carcinoma-in-situ and missing information from a total of 2474 patients with BC. There were 952 (47.1%) patients in the Luminal A group, 236 (34.1%) in the Luminal B group, 236 (11.7%) in the TNBC group and 142 (7.1%) patients in the HER2 enriched group. HER2-enriched patients had the shortest survival (p < 0.001), with 113.70 ± 7.17 months of DFS and 125.45 ± 3.03 months of OS. For patients who received Herceptin, DFS was 101.50 ± 6.4 months and OS was 118.14 ± 6.16. Patients who did not receive Herceptin had 92.79 ± 18 months of DFS and 94.44 ± 15.23 months of OS. Conclusion: The HER2-enriched subgroup had the worst prognosis despite receiving targeted therapy. While the duration of DFS and OS had no significant difference between TNBC and Luminal A-B subgroups, HER2 enriched subgroup had significantly shorter survival when compared to any other subgroup. HER2-enriched subgroup had a 10-fold greater risk of death compared to the Luminal A subgroup.

Diffusion tensor imaging and diffusion-weighted imaging on axillary lymph node status in breast cancer patients.

PURPOSE This article will examine the usefulness of diffusion tensor imaging (DTI) and diffusion-weighted imaging (DWI) on the assessment of axillary lymph nodes (ALN) of breast cancer patients. METHODS Axillary lymph nodes in 66 breast cancer patients were examined by DTI and DWI, and the largest lymph node with increased cortical thickness in axilla was selected. Morphological features, apparent diffusion coefficient (ADC), volume anisotropy, and fractional anisotropy values were measured by using a special software. Imaging findings and histopathological results were recorded. RESULTS Metastatic ALN were detected in 43 (65.1%) patients. Cortical thickness of the metastatic ALN was significantly higher than the non-metastatic ALNs (P < .001), and the long-axis-to-shortaxis ratio was significantly lower in metastatic ALNs (P < .001). There was a statistically significant difference between the ALN status and fatty hilum presence (P < .001). Apparent diffusion coefficient values of metastatic ALNs were statistically lower than those of non-metastatic ALNs (P < .001) using a cutoff value of 1.26 × 10-3 mm2 /s for b=500 ADC and 1.21 × 10-3 mm2 /s for b=800 ADC which had 97.7% sensitivity and 91.3% specificity. Fractional anisotropy and volume anisotropy values were significantly different between both groups. A cutoff value of 0.47 for b-500 fractional anisotropy had 83.7% sensitivity, 69.6% specificity 69.6% positive predictive value, and 83.7% negative predictive value. A cutoff value of 0.33 for b=500 volume anisotropy had 76.7% sensitivity, 78.3% specificity, 86.8% positive predictive value, and 64.3% negative predictive value. CONCLUSION Apparent diffusion coefficient value of metastatic ALNs was found to be significantly lower than those of non-metastatic ALN, and DTI metrics of metastatic ALN were found to be significantly higher than those of non-metastatic ALN. Overall, ADC had a better diagnostic performance than morphological features, fractional anisotropy, and volume anisotropy. Diffusion tensor imagingderived diffusion metrics may be used to complement breast magnetic resonance imaging in the future after further standardization of the imaging parameters.
