Purpose This study aimed to investigate the effects of preoperative biliary drainage and different preoperative biliary drainage methods in patients with mechanical jaundice who underwent pancreaticoduodenectomy for periampullary tumors. Methods Patients with periampullary tumor with mechanical jaundice who were operated on at the U.U. General Surgery Department between October 2015 and August 2021 were included in this study. The patients were divided into endoscopic biliary drainage, percutaneous transhepatic biliary drainage, and nonpreoperative biliary drainage groups. Patients’ demographic and clinical characteristics were analyzed. Results Of the 173 patients included in the study, 121 underwent preoperative biliary drainage. Of these 121 patients, 32.2% underwent endoscopic biliary drainage. Age, sex, comorbidities, and weight loss were similar in all groups. Cholangitis was the most common complication in the endoscopic biliary drainage and percutaneous transhepatic biliary drainage groups. Postoperative surgical site infection and Clavien‒Dindo ≥ 3b complications were significantly higher in the endoscopic biliary drainage group (P P = .031, respectively). The length of stay was significantly higher in the endoscopic biliary drainage group (P = .044). Mortality and readmission were similar in all groups. Conclusions Routine preoperative biliary drainage in periampullary tumor with mechanical jaundice does not reduce complications. Percutaneous transhepatic biliary drainage results in a faster decrease in bilirubin and lower infectious complication rates, but it may cause serious technique-related problems.

Background The aim of this study was to examine whether or not there was a difference in corpus callosum shape between patients with mild to moderate and severe obstructive sleep apnea (OSA) compared with patients who have simple snoring. Methods The landmark coordinate data was obtained from the mid-sagittal magnetic resonance imaging (MRI) images of 70 patients who underwent polysomnography. For comparisons, mild and moderate OSA groups were combined and analyses were performed on three groups; simple snoring/control group, mild or moderate OSA group, and severe OSA group. Results The corpus callosum shape of controls was significantly different from that of the severe OSA group. The most prominent deformities were observed in the genu and rostral body of the corpus callosum for the patients with severe OSA. No significant difference was found between mild/moderate OSA group and simple snoring group in terms of global corpus callosum shape. Conclusion The data demonstrated that severe OSA patients have structural changes in the corpus callosum and deformities may vary as the severity of disease changes.

The short form of the Impulsive Behavior scale (S-UPPS-P) is a widely used scale to measure multiple impulsive personality traits; although it has been translated into many languages, no Turkish translation has been studied to date. Our study had two aims. First, we tested the validity and reliability of the Turkish version of the S-UPPS-P for adolescents. Second, we examined impulsive trait characteristics exhibited by adolescents with ADHD, compared to a community sample. We evaluated the psychometric properties of the Turkish S-UPPS-P scale in 384 adolescents aged 11-18 and tested correlations with ADHD symptoms by assessing 41 adolescents diagnosed with ADHD. Our results showed that with a few slight modifications the Turkish translation of the S-UPPS-P scale can validly assess impulsive trait characteristics for Turkish adolescents. The subscales of lack of premeditation, positive urgency, and negative urgency efficiently distinguished between adolescents with ADHD and control subjects. This is the first scale to evaluate the multidimensional nature of impulsivity in Turkish adolescents. This scale is capable of screening various facets of impulsivity in typically developing adolescents as well as those with ADHD, enabling us to enhance our understanding of possible risks for comorbid diseases in the latter group.

In the course of SARS-CoV-2 infection, early prognostic evaluation is important since clinical symptoms may worsen rapidly and may be fatal. Inflammation plays an important role in the pathogenesis of COVID-19 and can cause myocardial damage which is common in severe COVID-19 patients. Therefore, novel inflammatory indexes and myocardial damage may be predictive of prognosis in patients with COVID-19. The aim of the study was to evaluate the role of cardiac troponin I (cTnI), modified Glasgow prognostic score (mGPS), systemic immune inflammation index (SII), prognostic nutritional index (PNI), and CRP to albumin ratio (CAR) in the outcome estimation of COVID-19 and to develop a risk model predicting the survival probability of COVID-19 survivors during early post-discharge.This was a single-center, observational, retrospective cohort study. Laboratory confirmed COVID-19 patients (n = 265) were included and grouped according to in-hospital mortality. ROC curve analysis was performed and Youden's J index was used to obtain optimal cutoff values for inflammatory indexes in discriminating survivors and non-survivors. Cox regression analysis was performed to assess the possible predictors of in-hospital mortality. A nomogram was constructed based on the Cox regression model, to calculate 7- and 14-day survival.The area under the ROC curve (AUC) of the variables ranged between 0.79 and 0.92 with the three highest AUC values for albumin, PNI, and cTnI (0.919, 0.918, and 0.911, respectively). Optimal threshold value for cTnI was 9.7 pg/mL. Univariate analysis showed that gender, albumin, CRP, CAR, PNI, SII, cTnI, and mGPS were significantly related to in-hospital mortality. The Cox regression analysis indicated that mGPS (p = 0.001), CRP (p = 0.026), and cTnI (p = 0.001) were significant prognostic factors.cTnI should not be considered merely as an indicator of myocardial damage. It also reflects the inflammatory phase and, along with other inflammatory markers, it should be included in risk models as a prognostic factor for COVID-19.

Purpose Osteoporosis is a systemic skeletal disease with a consequent increase in fractures rates. Osteoporosis may be primary which is related with normal aging, or secondary which occurs in the presence of an underlying disease or medication. Osteoporosis is one of the significant comorbidities in chronic obstructive pulmonary disease (COPD). In this study, we aimed to investigate the presence of osteoporosis and the influencing factors in COPD patients. Patients and Methods This is a two-group comparison study that was conducted among 30 COPD patients on inhaled corticosteroid (ICS) and 33 controls. It was conducted in the outpatient clinics at the Departments of Physical Medicine and Rehabilitation and Pulmonary Diseases in Bursa Uludag University Hospital, a tertiary reference center, in the northwest region of Turkey. For both groups, demographic variables, osteoporosis risk questioning, body mass index (BMI), bone mineral density (BMD), biochemical blood tests, vertebral fractures on lumbar and thoracic x-rays were recorded. COPD patients were also evaluated for lung functions via spirometry. Results Thirty patients with COPD (Group 1) and 33 controls (Group 2) were included in the study. Comparing the demographic and biochemical data, no difference was found between the groups except smoking (pack/year) (p

Increased risk of pancreatic cancer may be associated with consumption of sugar containing foods. The aim of this study was to evaluate the effect of peach nectar containing high fructose corn sirup (HFCS) consumption in a pancreatic carcinogenesis rat model induced by 7,12-Dimethyl benzanthracene (DMBA). Fifty-day-old male Sprague Dawley rats were fed with peach nectar containing HFCS + chow, peach nectar containing sucrose + chow and only chow. After 8 mo, feeding period, each group was divided into two subgroups, in which the rats were implanted with DMBA and no DMBA (sham). Histologic specimens were evaluated according to the routine tissue processing protocol. The animals withad libitumaccess to pn-HFCS, pn-sucrose and chow (only) showed significant differences in chow consumption and glucose level. Necropsy and histopathologic findings showed tumor formation in the entire group treated with DMBA. Excluding one rat in chow group, which was classified as poorly differentiated type, the others were classified as moderately differentiated pancreatic ductal adenocarcinoma (PDAC). This study demonstrated that daily intake of HFCS did not increase body weight and there was no effect of peach nectar consumption on the development of PDAC induced by DMBA in rats.

We aimed to investigate the clinical, immunological, and genetic factors affecting the response to anti-TNFα (tumor necrosis factor-α) and interleukin-12/23 therapies and drug survivals.A total of 180 patients were divided into two groups: 89 patients who used at least two biologic agents, with the initial biologic agent used less than 12 months (group A), and 91 biologic-naive patients who have been receiving a single biologic agent for more than 12 months (group B). ELISA (enzyme-linked immunosorbent assay) was used to analyze anti-drug antibodies (ADAs) in blood samples. Clinical data of the patients were retrospectively analyzed. HLA-SSO (sequence-specific oligonucleotide) Typing Kits were used for HLA-C typing. IBM SPSS v.21 was used for statistical analysis.RAlthough our study is retrospective of a relatively low number of patients, this is a preliminary study focusing on two different patient populations based on therapy response.

In any clinical case, a decision is made with the maximum possible accuracy. To achieve such accuracy, in the presence of multiple diagnostic tests or biomarkers, biomarker combinations aim to achi...

Background Combination of hydroxychloroquine and azithromycin for the treatment of coronavirus disease 2019 (COVID-19) carries increased risk of corrected QT (QTc) prolongation and cardiac arrhythmias. Objective To characterize the ventricular repolarization indexes which are associated with malignant ventricular arrhythmias in patients treated with hydroxychloroquine and concomitant azithromycin for COVID-19. Method A total of 81 patients who had hydroxychloroquine and azithromycin combination therapy because of possible or reverse-transcription polymertase chain reaction (RT-PCR) confirmed diagnosis of COVID-19 were included in the study. Baseline and control electrocardiograms (before and after treatment) were analyzed retrospectively. Tp-e interval, Tp-e/QT and Tp-e/QTc ratios, which are ventricular repolarization indexes, were calculated. Results While there was no significant increase in QTc interval in patients receiving combination therapy, there was a significant increase in ventricular repolarization indexes. Conclusion The increase in ventricular replarization indexes is associated with the risk of arrhythmia. In patients using QTc prolonging medication for COVID-19 treatment, QTc monitoring alone may not be sufficient to follow-up for arrhythmia. Even if there is no prolongation in QTc, an increase in ventricular repolarization indexes may be seen (Tab. 5, Ref. 37).

Survival trees and forests are popular non-parametric alternatives to parametric and semiparametric survival models. Conditional inference trees (Ctree) form a non-parametric class of regression trees embedding tree-structured regression models into a well-defined theory of conditional inference procedures. The Ctree is applicable in a varietyof regression-related issues, involving nominal, ordinal, numeric, censored, as well as multivariate response variables and arbitrary measurement scales of covariates. Conditional inference forests (Cforest) consitute a survival forest method which combines a large number of Ctrees. The Cforest provides a unified and flexible framework for ensemble learning in the presence of censoring. The random survival forests (RSF) methodology extends the random forests method enabling the approximation of rich classes of functions while maintaining generalisation errors low. In the present study, the Ctree, Cforest and RSF methods are discussed in detail and the performances of the survival forest methods, namely the Cforest and RSF have been compared with a simulation study. The results of the simulation demonstrate that the RSF method with a log-rank score distinction criteria outperforms the Cforest and the RSF with log-rank distinction criteria. Key words: tree-based methods, conditional inference trees, conditional inference forests, random survival forests.

Magnesium (Mg) is the second most abundant intracellular cation and plays a significant role in immune system and cardiac protection. Mg deficiency contributes to chronic low-grade inflammation leading to cardiovascular diseases, and low Mg level exacerbates virus-induced inflammation. The aim of the study was to investigate whether serum magnesium level is associated with myocardial damage and prognosis of COVID-19. This was a single-center, observational retrospective study of patients with COVID-19. The study population was divided into two groups according to in-hospital mortality: a survivor group (SG) and a non-survivor group (NSG). Myocardial damage was defined as blood levels of cardiac troponin I (cTnI) above the 99

We investigated the effect of short-term telmisartan usage in addition to lifestyle changes such as diet and exercise on insulin resistance, lipid metabolism, and serum adiponectin and tumor necrosis factor-alpha (TNF-α) levels in hypertensive patients with metabolic syndrome (MetS).A total of 36 hypertensive patients with MetS were randomized to telmisartan and control groups in an open-labeled prospective study.There were significant decreases in anthropometric variables of patients according to baseline measurements in both groups at the end of the study. Serum insulin level and insulin resistance assessed by homeostasis model assessment-insulin resistance were decreased significantly in the telmisartan group (P = 0.040 and P = 0.034, respectively) compared with the controls, while there was no statistically significant change in the lipid profiles of the two groups. Serum adiponectin level was increased by 19.1% ± 41.7% in the telmisartan group, but intergroup analysis revealed no significant change. There was also no significant change in serum TNF-α level in either group.It has been observed that even short-term telmisartan treatment had favorable effects on insulin resistance and glucose metabolism compared with lifestyle changes alone. The fundamental effect of telmisartan treatment on insulin resistance renders it a good therapeutic option for hypertensive patients with MetS.

Objective To investigate the shape differences in the putamen of early-onset Parkinson’s patients compared with healthy controls and to assess and to assess sub-regional brain abnormalities. Methods This study was conducted using the 3-T MRI scans of 23 early-onset Parkinson’s patients and age and gender matched control subjects. Landmark coordinate data obtained and Procrustes analysis was used to compare mean shapes. The relationships between the centroid sizes of the left and right putamen, and the durations of disease examined using growth curve models. Results While there was a significant difference between the right putamen shape of control and patient groups, there was not found a significant difference in terms of left putamen. Sub-regional analyses showed that for the right putamen, the most prominent deformations were localized in the middle-posterior putamen and minimal deformations were seen in the anterior putamen. Conclusion Although they were not as pronounced as those in the right putamen, the deformations in the left putamen mimic the deformations in the right putamen which are found mainly in the middle-posterior putamen and at a lesser extend in the anterior putamen.

Background: In most healthy individuals, blood pressure (BP) shows a circadian rhythm. Being non-dipper increases cardiovascular risk in normotensive and hypertensive individuals. Nocturnal dipping shows a correlation with the state of inflammation. Objetive: To investigate the relationship between inflammation-based indexes and nocturnal BP pattern in normotensive individuals. Method: This is a retrospective study that included patients evaluated with ambulatory BP monitoring (ABPM). A total of 131 normotensive individuals were included and grouped as dippers and non-dippers. The normality of the data was verified with a Shapiro-Wilk test. We compared ABPM variables and inflammation-based indexes derived from blood tests (monocyte to high-density lipoprotein ratio [MHR], platelet to lymphocyte ratio [PLR], neutrophil to lymphocyte ratio [NLR], and systemic immune-inflammation index [SII]) between groups. The independent samples t-test and Mann-Whitney U test were used for comparing variables with normal and non-normal distributions, respectively. The Pearson's chi-squared test was used to compare categorical variables, and Spearman's correlation coefficient was used to examine the relationships between variables. A receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performances of inflammation-based indexes. The level of statistical significance was 5%. Results: The study included 131 patients (mean±standard deviation [SD] age 49.2±15.1 years, 58 [76.0%] of which were women). SII was significantly higher in the non-dipper group (p=0.033). Significant negative correlations were observed between the change in systolic BP [ΔSBP] and SII (r=-0.172, p=0.049) and between ΔSBP and PLR (r=-0.179, p=0.040). Conclusion: SII is a predictor of nocturnal BP pattern in normotensives.

Carpal tunnel syndrome (CTS) is the most common upper extremity entrapment neuropathy and various risk factors have been implicated in the etiology. In this study, we aimed to determine whether anthropometric measurements are independent risk factors for CTS. Patients with symptoms of CTS (n = 27) and asymptomatic controls (n = 27) were enrolled following electrophysiological confirmation. Body mass index (BMI) was recorded and anthropometric measurements of the hand were made by a digital caliper. BMI, wrist width, wrist depth, palm length, hand width, wrist ratio, wrist/palm ratio, and wrist/hand ratio were significantly higher in the CTS group. BMI, wrist ratio, wrist/palm ratio, and wrist/hand ratio were independent variables in the logistic regression analysis; wrist ratio was the only significant predictor of CTS. Patients with a wrist ratio higher than 0.69 were 8.2 times more likely to have CTS. This study suggests that wrist ratio may be considered as an independent risk factor for CTS. Clin.

Objective To evaluate the association between nasal airway function and Eustachian tube (ET) functions and their impact on tympanoplasty in patients with chronic suppurative otitis media (CSOM). Materials and methods The study group (CSOM group) consisted of 33 patients scheduled to undergo tympanoplasty for CSOM. Two control groups were formed: a nasal septal deviation (NSD) group of 25 patients scheduled to undergo nasal surgery for NSD, and a control group of 25 healthy individuals with no otologic or rhinologic symptoms. ET functions were assessed tympanometrically with automatic Williams test (ETF1) and modified pressure equalization inflation-deflation test (ETF2) and nasal functions were analyzed using acoustic rhinometry and rhinomanometry. The patients in the CSOM group underwent tympanoplasty, and tests were repeated at the end of the 3rd postoperative month. Results Both acoustic rhinometry and rhinomanometry revealed similar nasal function in the CSOM and NSD groups, which was inferior to that of the control group. The CSOM group had the worst ET function. Dysfunctional ETs in the CSOM group improved at 3 months postsurgery, and all groups had a similar outcome regarding ET functions. The outcome of ear surgery was not affected by nasal function, and the graft take rate was 90%. Conclusion Patients with NSD had generally poor ET function; however, this did not affect the outcomes of tympanoplasty. The preoperative ET function results were inconsistent with the results following tympanoplasty; therefore, they were not predictive of need for septoplasty. Thus, we do not universally recommend surgical correction of NSD prior to ear surgery; however, this decision should be made on an individual basis.

INTRODUCTION: In this study, we aimed to discuss the data of patients with acute ischemic stroke with intravenous thrombolytic therapy (IV-tPA) in our clinic in the light of the literature. METHODS: Seventy patients with acute ischemic stroke diagnosed between April 2016 and 2017 who received IV-tPA were included in the study. Demographic, radiological and clinical data of the patients were recorded. The intracranial hemorrhages and neurological status at the end of the third month were evaluated with the modified MRS score and the National Stroke Health Scale (NIHSS) scores within 3 months after discharge. The values of the symptom-needle time, the Alberta stroke program, the early computerized tomography score (ASPECT) and the NIHSS scores at the first application and follow-up were analyzed. RESULTS: 28 of the patients were female and 42 were male and the mean age was 66.44 ± 13.47. Thirty-nine (55.7%) of the patients were referred to emergency services and 31 (44.3%) were directed to thrombolytic therapy from the emergency department of other hospitals. The initial NIHSS scores at the time of admission were 14.27 ± 4.26, while the NIHSS scores at the 24th hour were 11.47 ± 5.85. The ASPECT score at the time of admission was 9.61 ± 0.81. The median symptom-to-needle time was 89.5 minutes (0-245). The median door-to-needle time was 77 minutes (20-187). During thrombolytic application, edema occurred in 4 patients and intrahepatic hemorrhage occurred in 1 patient. At the end of the third month, 20 patients (28.5%) had complete recovery of neurological disability and 9 (12.9%) were exiting. DISCUSSION AND CONCLUSION: The results of this study show that IV-tPA treatment is a safe and effective treatment for acute ischemic stroke, similar to past studies, and that this treatment reduces the disability at the end of the third month.

The patients with non small cell lung cancer (NSCLC) treated with definitive conformal radiotherapy (RT) were evaluated in terms of side effects and survival. Normal tissue complication probability (NTCP) was calculated for 68 patients treated between 2009 and 2012. Clinical and dosimetric factors were analyzed. The median dose of 63 Gy (range: 54 to 70 Gy) was given with conformal RT with blocks (n = 37), 3-dimensional conformal RT (3DCRT) (n =11), or intensity-modulated RT (IMRT) (n = 20). Acute grade 1 to 2 radiation pneumonitis (RP) was seen in 13% of the patients. No significant relationship was found between RP and treatment and dosimetric factors (p > 0.05). There was a positive correlation between median "mean lung dose" (MLD) (17 Gy), lung V30 (20.5%), and NTCP (14%) (p < 0.001). Median and 2-year overall survival (OS) and progression-free survival (PFS) were 27 and 18 months and 51% and 42%, respectively. In univariate analysis, significant dose range for survival was found between 59.4 and 63 Gy (p < 0.01). In multivariate analysis, response (p = 0.001), fraction dose of 1.8 Gy (p = 0.002), MLD 59.4 Gy (p = 0.01), and tumor biologically effective dose (BED)3(Gy) 5100.8 (p = 0.01) for PFS were found to be favorable factors. In our study, we found a linear correlation between NTCP and MLD for RP risk estimation in patients with NSCLC. Therapeutic dose range where MLD can be kept under 20 Gy with significant survival benefit was found between 59.4 and 63 Gy. Increased therapeutic efficacy will be possible using risk-adaptive RT techniques.

Objectives We investigate the relationship between the severity of vascular disease and epicardial adipose tissue thickness(EAT-t) and the neutrophil/lymphocyte (NEU/LY) ratio in acute stroke patients. Methods Seventy-six patients and 38 healthy controls were included in the study. Strokes were divided into three groups: lacunar infarction, middle cerebral artery infarction (MCA), and other arterial infarcts. Patients were assessed using the GCS (Glasgow coma scale) and NIHSS (National Institutes of Health Stroke Scale) scales. In addition to laboratory measurements, EAT-t was evaluated in all patients by using echocardiography. Results The EAT-t value and NEU/LY ratio were higher in the patient group than in the control group. The MCA group was found to have a significantly higher NEU/LY ratio than the lacuna group (p = 0.017) as well as the other patient (p = 0.025) group. There was a positive correlation of NIHSS score with EAT-t (r = 0.291; p = 0.013), and NEU/LY ratio (r = 0.289; p = 0.014). Conclusion The EAT-t and NEU/LY ratio were high in patients with acute ischemic stroke patients. The higher ratio of NEU/LY compared to other infarcts in the MCA group. These findings support the relationship between acute ischemic stroke severity and inflammation .

Most of the studies in medical and biological sciences are related with the examination of geometrical properties of an organ or organism. Growth and allometry studies are important in the way of investigating the effects of diseases and the environmental factors effects on the structure of the organ or organism. Thus statistical shape analysis has recently become more important in the medical and biological sciences. Shape is all geometrical information that remains when location, scale and rotational effects are removed from an object. Allometry, which is a relationship between size and shape, plays an important role in the development of statistical shape analysis. The aim of the present study was to compare two different models for allometry which includes tangent coordinates and principal component scores of tangent coordinates as dependent variables in multivariate regression analysis. The results of the simulation study showed that, the model constructed by taking tangent coordinates as dependent variables is more appropriate than the model constructed by taking principal component scores of tangent coordinates as dependent variables, for all sample sizes.

Objective To evaluate the impact of nasal septum deviation (NSD) and septoplasty on eustachian tube (ET) functions. Material and methods The study was designed as a prospective controlled study and conducted in a tertiary referral center. A study group of 25 patients who were scheduled for septoplasty for NSD; and a control group of 25 healthy individuals having no ear or nose symptoms were formed. Tympanometric analysis of ET function, subjective and objective analysis of nasal functions with acoustic rhinometry and rhinomanometry were performed. Patients in study group underwent nasal surgery and tests were repeated at postoperative 1st and 3rd months. Results Eustachian tube functions of study group were significantly worse than the control group (P = 0.032). ET functions were found to be poorer as the nasal airway resistances increase which was found to be close to significance (P = 0.056). One and 3 months after corrective surgery, both nasal airway functions and ET functions improved significantly reaching to the level of control group. Conclusions Nasal septum deviation was associated with higher rates of ET dysfunction, which could be improved by the nasal surgery. However, in some patients, nasal surgery itself caused ET dysfunction in the early postoperative period.

To investigate the association between the perception of expressed emotion and psychopathology of school-going adolescents in a non-clinical sample.The cross-sectional field study was conducted in Kocaeli, Turkey, and comprised high-school students during the 2014-15 school years. Data was collected using the Information Collection Form, Strengths and Difficulties Questionnaire and Shortened Level of Expressed Emotion Scale. SPSS 21 was used for data analysis.Of the 487 subjects, 295(60.57%) were girls and 192(39.43%) were boys. The overall median age was 16 (inter-quartile range: 15-17 years). There were significant positive relationships between the scales in terms of emotional problems (p0.001), behavioural problems (p0.001), Attention-deficit/hyperactivity disorder (p0.001), and peer relationship problems (p0.001). There was also a negative significant relationship between pro-social behaviours and expressed emotion (p0.001).The concept of perceived expressed emotion in non-clinical adolescents is useful in alarming clinicians and preventing mental disorders.

Purpose: To investigate the olfaction and taste functions in obese female patients and the association between serum ghrelin and leptin levels compared with healthy controls. Methods: Fifty-two obese women, who have a body mass index >30 kg/m(2), and 15 healthy women were included in the study. After 8 hrs fasting, blood samples were taken for serum biochemical parameters, ghrelin, and leptin level measurement. For the quantitative assessment of olfactory function, all participants underwent an N-butanol threshold test and odor identification test using 12 Sniffin' Sticks (R) fragrance sticks. The gustatory function was tested by administering a whole-mouth above threshold test using sucrose solutions. Results: The sucrose taste threshold score in obese women was significantly higher than the controls (P = 0.004). We found positively significant correlation between serum ghrelin levels and n-butanol threshold scores in obese women (r = 0.300, P = 0.031). N-butanol smell threshold was not significantly different between the two groups (P = 0.149), while the Sniffin' Sticks smell test scores were significantly lower in obese women compared with the controls (P = 0.007). Serum leptin levels were also significantly higher in obese women (P < 0.001) although there was no significant difference in serum ghrelin levels between the two groups (P = 0.768). There was no correlation between serum leptin levels and Sniffin' Sticks scores, n-butanol, and sucrose taste threshold scores in obese women. Conclusions: These results might suggest that leptin, which is an anorexigenic peptide, may have a negative effect on taste and smell functions. More studies are warranted to elucidate the exact role of ghrelin secretion on olfaction and taste functions.

AIM: The aim of this study was to evaluate thymic epithelial tumors (TETs) for treatment outcomes and prognostic factors on survival. BACKGROUND: TETs are very rare neoplasms and multidisciplinary approach is recommended according to prognostic factors. MATERIALS AND METHODS: Between 1995 and 2013, 31 patients were treated with median 5400 cGy (range: 1620–6596 cGy) radiotherapy (RT). Eleven patients received adjuvant or concurrent chemotherapy. There were 25 thymomas, 4 thymic carcinomas and 2 thymic neuroendocrin carcinomas. According to Masaoka, staging and WHO classification, cases were divided to good (n: 10), moderate (n: 9) and poor (n: 12) prognostic risk groups. Survival was calculated from diagnosis. RESULTS: In January 2016, 22 cases were alive with median 51.5 months (range: 2–170.5) follow-up. Recurrences were observed in 29% of patients in median 29.5 months (range: 6.5–105). Local control, mean overall (OS) and disease-free survival (DFS) rates were 86%, 119 and 116 months, respectively. There was a significant difference for R0 vs. R+ resection (81% vs. 43%, p = 0.06, and 69% vs. 46%, p = 0.05), Masaoka stage I–II vs. III–IV (75% vs. 52%, p = 0.001, and 75% vs. 37%, p

BACKGROUND: The purpose of this study is to detect the mortality predictive power of new Glasgow coma scale, age, and arterial pressure (GAP) scoring system in major trauma patients admitted to the emergency department (ED). METHODS: A total of 100 major trauma patients admitted to Uludag University Faculty of Medicine ED who were 18 years of age or more were included in the study. In this prospective study, revised trauma score (RTS), injury severity score (ISS), trauma-related ISS (TRISS), Mechanism, GAP (MGAP) and GAP scores of the patients were calculated. RESULTS: A significant positive correlation was established between ISS, TRISS, MGAP, and GAP in predicting in-hospital mortality (p

Objective: The aim of this study was to investigate the prevalence of peer bullying among the adolescents, deter-mine the risk factors of PB and determine the relationship between peer bullying and psychiatric symptoms and expressed emotion. Methods: The sample of the study consisted of 5th, 6th, 7th, and 8th grade students, and the students who were selected with simple random sampling method were divided into four groups as the victim, bully, bully/victim and no peer bullying. In the study, a Personal Information Form, Olweus Bullying Questionnaire, Strength and Difficulties Questionnaire and Shortened Expressed Emotion Scale were used as data collection tools. Results: Prevalence of peer bullying of secondary school was found to be %47 (31.4% victim, 4.6% bully, 11% bully/victim). When the study groups were compared in terms of subscales, behavioral problems and emotional problems were significantly higher in both the bully and the victim groups, while prosocial behaviors were found to be significantly less in these two groups. However, teenagers, who were a victim or a bully, were found to perceive their families significantly less emotionally supportive and intrusive compared to their peers who were not a victim or a bully. The perception of the family as intrusive increased the chances of being a victim by 1.04 times and a victim/bully by 1.08 times. The lack of emotional support increased the chances of being a bully/victim by 1.03 times. Conclusion: Our study reveals that there is a relationship between emotional-behavioural problems and peer bullying. It has been found that being part of bully, victim or both forms of peer bullying is significantly related to psychopathology. The findings showed the importance of family climate in peer bullying

Background Several genes encoding different Th1 and Th2 cytokines may play crucial roles in host susceptibility to Condyloma acuminatum (CA). Mannose-binding lectin (MBL) is a serum lectin that mediates complement activation, and it is a member of innate immune system. MBL gene polymorphisms are considered to be associated with several infectious diseases. Objective In this study, we investigated the association between cytokines and MBL gene polymorphisms with CA. Methods Forty patients with CA and 40 healthy controls were enrolled in this study. These patients had not responded to at least a therapy modality and all patients had recurrent lesions. Polymorphism of cytokine [Th1 cytokines; tumour necrosis factor-α and interferon (IFN)-γ, Th2 cytokine; IL-6, T regulatory/suppressor cytokines; IL-10 and transforming growth factor-β] genes studies were performed by Polymerase chain reaction sequence-specific primers method and MBL genotyping were studied by PCR-restriction fragment length polymorphism method. Results With the aid of agglomerative hierarchical cluster analysis, we categorized subjects into two main clusters (cluster 1; formed by the majority of patients with CA, cluster 2; formed by the majority of healthy controls), which were found to have significantly different distributions of IL-6 and MBL genotypes. Frequencies of IL-6 (-174) G/G (P

Both cluster of differentiation (CD)4+ and CD8+ T lymphocytes play key roles in immunity to Brucella, in part because they secrete interferon (IFN)-γ and activate bactericidal functions in macrophages. Therefore, use of markers of macrophage activation may have diagnostic and prognostic significance. High-mobility group-box 1 protein (HMGB1), a late-onset pro-inflammatory cytokine, is secreted by activated macrophages. Soluble hemoglobin scavenger receptor (sCD163) is a specific marker of anti-inflammatory macrophages. The aim of this study was to investigate the diagnostic value of HMGB1 and sCD163 concentrations in brucellosis and its various clinical forms. Serum HMGB1 and sCD163 concentrations in 49 brucellosis patients were compared with those in 52 healthy control subjects. Both serum HMGB1 and sCD163 concentrations were significantly higher in brucellosis patients than in healthy controls (P

High fructose corn syrup (HFCS) is one of the most used sweeteners in the food industry. Health concerns regarding the consumption of HFCS-containing foods have developed in parallel with the increasing amount of people who become overweight. This study was conducted to investigate whether HFCS-containing peach nectar (pn-HFCS) consumption has more detrimental effects on anthropometrical and biochemical parameters compared with sucrose-containing peach nectar (pn-sucrose). Fifty-day-old Sprague Dawley rats were divided into three groups and were fed (A) pn-HFCS + ad libitum chow, (B) pn-sucrose + ad libitum chow and (C) only ad libitum chow for 7 months. The percentage change in body weight (PCBW), body mass index (BMI), and Lee index were calculated, and serum triglyceride, glucose, insulin and leptin concentrations were measured. The PCBW, BMI, Lee index, serum triglyceride, glucose, insulin and leptin concentrations were insignificant among the three groups. We can suggest that peach nectar consumption resulted in more energy intake than the control and since pn-HFCS group consumed more chow than the pn-sucrose group. The results show that long term daily HFCS or sucrose consumption in peach nectar is not associated with weight gain and does not stimulate metabolic changes in Sprague Dawley rats.

The purpose of this study is to detect the predictive power of the modified early warning score with rapid lactate level (ViEWS-L) on mortality in critical patients over the age of 65 years admitted to the emergency department (ED). A total of 616 non-traumatic patients admitted to the Uludag University Faculty of Medicine ED who were 65 years of age or older were included in this study (Ethics board number: 2015-4/8). In this prospective study; the ViEWS-L score of the patients were calculated. The results have been evaluated with rate of mortality in the first 24 h starting from submission. The area under the ROC curve was found 0.872 and the cut-off value to detect mortality was found 10.83 for the ViEWS-L score. In the model obtained by the univariate binary logistic regression analysis, ViEWS-L score was found statistically significant and it was determined that mortality risk increased 1.286 times for each unit increase in the score of ViEWS-L score. As a result of this research, it was found that ViEWS-L scoring system is effective in determining the mortality of 65 years and older patients.

Aim. To investigate the effect of exenatide treatment on serum ghrelin levels in obese female patients with type 2 diabetes mellitus.Methods. Fourteen female patients with type 2 diabetes mellitus being treated with metformin and exenatide were enrolled. A mixed meal test was applied to the patients while continuing with their daily medications. Blood samples were taken before and at 60, 120, and 180 minutes following mixed meal test to measure serum total ghrelin, glucose, and insulin levels. The following week, exenatide treatment of the patients was paused for 24 hours and the same experimental procedures were repeated.Results. Serum ghrelin levels were suppressed significantly at 180 minutes with exenatide treatment compared with baseline (294.4±57.5versus234.5±59.4 pg/mL) (p<0.001). Serum ghrelin levels at 180 minutes were statistically different when percentage change in serum ghrelin levels after mixed meal tests with and without exenatide usage were compared (p=0.001). Estimated total area under the curve values for serum ghrelin concentrations was also significantly lower with exenatide compared with omitted treatment (p=0.035).Conclusion. These results suggest that the effect of exenatide on weight loss may be related with the suppression of serum ghrelin levels, which is an orexigenic peptide.

This study was aimed at adapting the weighted Kaplan-Meier method to time-dependent ROC curve analysis. The performances of these two time-dependent ROC curve methods were compared, in which the Kaplan-Meier estimator and weighted Kaplan-Meier estimator were used. An application was presented for pancreatic cancer patients to evaluate the prognostic ability of the CA19-9 antigen. A simulation study was performed for different scenarios to see the performance of the proposed method. In all situations, it is observed that the AUC values that were obtained by the weighted time-dependent ROC (WTDR) curves more closely approximated the real AUC values than the classical time-dependent ROC (TDR) curve method and has got smaller mean square error rates.

The purpose of this study was to establish facial soft tissue norms for Turkish young adults. Anthropometric measurements of the facial soft tissue were taken from 281 female and 149 male Turkish adults aged between 18 and 24 years. The soft tissue facial profiles were digitally analyzed using linear (17 vertical and 10 horizontal) measurements made with standardized photographic records, taken in a natural head position, to determine the average soft tissue facial profile for males and females. A statistically significant difference was found between males and females in 20 of 27 measurements taken (p < 0.001). The most prominent differences between the sexes were observed in the measurements taken from the face region. Results were compared with other ethnic groups.

Statistical shape analysis, a relatively a new method for biological research, compares body forms by using specific landmarks determined by anatomical prominences. In this study, we aimed to identify normal facial asymmetry between the right and the left sides of the face. Facial landmark data were collected from two-dimensional digital images of 321 young healthy subjects (150 males and 171 females). These data were analysed using Euclidean distance matrix analysis. The number of significantly asymmetric linear distances between the two halves of the face was greater in females than in males. We found that the left side of the face was most commonly dominant in both males and females. Such data may be useful in establishing a database for future similar studies.

Hepatitis B virus (HBV) and hepatocellular carcinoma (HCC) recurrences affect both patient and graft survivals post-orthotopic liver transplantation (OLT) in HBV patients with HCC. We analyzed the relationship between HBV and HCC recurrence in a large cohort of HBV-OLT patients with versus without HCC.Two hundred eighty-seven HBV patients with OLT (72 also with HCC) were included in the study. Mean follow-up in the post-OLT period was 31.7 +/- 24.7 (range, 3-119) months.Post-OLT HBV recurrence observed in 10.1% of patients was more prevalent among the HCC group; 23.6% versus 5.5% in patients with and without HCC, respectively. The mean interval for the development of HBV recurrence was 39.5 +/- 28.5 (range, 2-99) months. Among 72 HCC patients, 8 patients (11.1%) had recurrent HCC, and 7 of them also had HBV recurrence. The mean interval for the development of HCC recurrence was 11.2 +/- 7.85 (range, 2-23) months after OLT. OLT patients with HCC with tumors exceeding the Milan criteria had worse 1-, 3-, and 5-year survival rates than patients with HCC meeting the Milan criteria. HBV and HCC recurrence-free survivals were significantly lower in patients with HCC and HBV recurrence, respectively. In the 7 patients with both HCC and HBV recurrence, mean HBV recurrence time was 9.42 +/- 6.75 months and mean HCC recurrence time was 9.57 +/- 6.75 months. There was a strong correlation between HBV and HCC recurrence times. Cox proportional hazards regression analysis showed that only HCC recurrence was a significant independent predictor of HBV recurrence (P.001; hazard ratio [HR] = 26.94; 95% confidence interval [CI] = 10.81-67.11). On the other hand, HBV recurrence (P = .013; HR = 5.80; 95% CI = 1.45-23.17) and nodule count (P = .014; HR = 13.08; 95% CI = 1.70-100.83) were significant predictors of HCC recurrence.HBV and HCC recurrences demonstrate a close relationship in patients with OLT.
