RESUMO
PURPOSE: Endometrial cancer (EC) is among the prevalent malignancies in gynecology, showing an increasing occurrence and mortality rate. The updated 2023 FIGO staging integrates both histopathological and molecular analyses, which significantly impact the prognosis and treatment approaches. This research aims to examine the effectiveness of MRI in identifying essential histopathological tumor features, including histological subtype, grade, and lymphovascular space invasion. METHODS: A total of 106 patients diagnosed with EC from February 2018 to December 2023 underwent preoperative pelvic MRI. Surgical procedures followed ESMO guidelines, with histopathological assessments using FIGO 2009 criteria. Two radiologists independently evaluated MRI images, measuring maximum tumor size, minimum tumor ADC value (using a free-hand ROI technique), and ADC tumor/myometrium ratio. MRI findings were compared with histopathological data. RESULTS: Peritoneal implant presence and tumor size exhibited significant differences between endometrioid adenocarcinoma (EAC) and non-endometrioid endometrial carcinoma (NEEC), with p values of < 0.001 and 0.003, respectively. Significant differences in age, tumor size, ADC tumor, and ADC tumor/myometrium between low-grade and high-grade tumors were observed, with p values of < 0.001, 0.004, 0.006, and 0.011, respectively. Increased tumor size, reduced ADC tumor, ADC tumor/myometrium, and pelvic peritoneal implant presence were significantly associated with LVSI, with p values of < 0.001, 0.001, 0.002, and 0.001, respectively. The AUC values for tumor size, ADC tumor, and ADC tumor/myometrium were 0.842, 0.781 and 0.747, respectively, in distinguishing between low and high-grade endometrial tumors. Similarly, obtained AUC values for predicting LVSI were 0.836, 0.719, and 0.696, respectively. CONCLUSION: Our study emphasizes MRI's role in predicting tumor characteristics such as histological subtype, grade, and LVSI based on updated FIGO criteria. By highlighting the potential of MRI, this research contributes to our comprehension of improving diagnostic and clinical management for EC. Further multicenter studies are warranted to validate these findings and establish MRI's role in EC management.
RESUMO
Immature teratomas (IT) are rare germ cell tumors with malignant behavior, distinct from the benign mature teratomas. Clinical differentiation poses challenges, demanding a comprehensive, multidisciplinary diagnostic approach. This case series delves into the detailed radiological imaging findings of ITs. Pelvic MRI was conducted on five cases with adnexal masses, all of which were histopathologically confirmed as ITs. Radiologically, larger tumor size and scattered fatty components were key diagnostic indicators. This study underlines the importance of comprehensive evaluation in IT diagnosis and management, with MRI as an essential tool in the clinical workflow.
RESUMO
OBJECTIVE: The aim of this study was to investigate the relationship between left-sided varicocele and epididymitis or epididymo-orchitis. MATERIALS AND METHODS: The study included 72 patients with left side epididymitis (EP) or epididymo-orchitis (EPO) (Group 1) and a control group of 72 patients without EP or EPO (Group 2). Those with right EP-EPO were excluded due to possible other underlying retroperitoneal pathologies causing varicocele. Groups were evaluated for presence of left side varicocele, varicocele grade and pampiniform plexus vein diameter. RESULTS: The average age was 38 ± 8.4 years (range, 18-50 years) in Group 1, and 36 ± 9.1 years (range, 16-47 years) in Group 2. Varicocele was significantly more common in patients with EP or EPO (p < 0.001). The rate of varicocele was 66.7% (48/72) in Group 1, and 22.3% (16/72) in Group 2. The median grade of varicocele was 2 in Group 1, and 0 in Group 2. Pampiniform plexus vein diameters were found to be significantly larger in patients with EP or EPO compare to patients without EP and EPO. The median vein diameter was 3.3 mm with the 25th and 75th percentiles at 2.7 and 3.8 mm, and was 1.9 mm with the 25th and 75th percentiles at 1.7 and 2.3 mm, respectively (p < 0.001). CONCLUSIONS: Left-sided varicocele was significantly more common in patients with EP or EPO and it is an important cause for the development of EP/EPO because of chronic venous stasis.

OBJECTIVES: The purpose of this study to determinate whether there is a relationship between the nutritional status and white matter integrity in older patients by using Diffusion Tensor Imaging (DTI). METHODS: The patients were evaluated by Mini-Nutritional Assessment Scale. The patients are categorized in the groups of well-nourished, risk of malnutrition, or malnourished, depending on the overall score> 23.5, 17-23.5, or 17; respectively. All patients had brain MRI and DTI. The mean diffusivity (MD), fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) values were calculated by ROI-based method in white matter tracts. RESULTS: Total of the 224 patients; 86 patients had normal nutrition status (group 1), 107 patients were diagnosed with malnutrition risk (group 2) and 31 patients were diagnosed with malnutrition (group 3). Significantly decreased FA values of genu of corpus callosum, forceps minor and significantly increased MD values of middle cerebellar peduncle, and superior frontooccipital fasciculus were detected in group 2 in comparison to group 1 (p < 0.05). After adjusting for the folate and age, MD and RD values of cingulum remained significantly higher and the AD values of superior cerebellar peduncle remained significantly lower in group 3 (p < 0.05). CONCLUSIONS: Malnutrition was associated with deteriorated DTI values, especially in cingulum and superior cerebellar peduncle. Assessing the nutritional status of older individuals is crucial to avoid its negative impact on brain. ADVANCES IN KNOWLEDGE: Early diagnosis of malnutrition-related impaired WM integrity is important for prevention and intervention, and DTI is a useful non-invasive technique to be used for this purpose.

PURPOSE: We aimed to differentiate serous borderline ovarian tumors (SBOT) from serous epithelial ovarian carcinomas (SEOC) using morphological and functional MRI findings, to improve the patient management. METHOD: We retrospectively investigated 24 ovarian lesions diagnosed with SBOT and 64 ovarian lesions diagnosed with SEOC. Additional to the demographic and morphological findings T2W signal intensity ratio, mean apparent diffusion coefficient (ADCmean) and total apparent diffusion coefficient (ADCtotal) values were analyzed and compared between two groups. RESULTS: Bilaterality, pelvic free fluid presence, serum CA-125 level (U/mL), presence of pelvic peritoneal implant were in favor of SEOC. Lower maximum size of solid component and solid size to maximum size ratio, dominantly cystic and solid-cystic appearance, exophytic growth pattern, presence of papiller projection and papillary architecture and internal branching pattern, higher T2W signal intensity ratio, ADCmean and ADCtotal values were in favor of SBOT. CONCLUSION: Our study revealed that morphological and functional imaging findings were valuable in differentiating BSOT from SEOC.

PURPOSE: To investigate the difference in FA (Fractional anisotropy), ADC (Apparent diffusion coefficient), RD (Radial diffusivity) and AD (axial diffusivity) values of white matter (WM) tracts in morbidly obese subjects before and after bariatric surgery (BS). MATERIALS AND METHODS: A group of thirty-nine morbidly obese subjects are evaluated before and 4-6 months after BS. ADC, FA, RD and AD values of 17 distinct neuroanatomic localizations are measured and DTI parameters are analyzed. RESULTS: Following the BS, the patients' mean BMI decreased from 47.665.21 to 31.723.97. A significant difference is displayed between the pre-surgery and post-surgery FA values of SLF, SFOF, ALIC, fornix, ILF, CST, MCP (p = 0.010, p < 0.001, p = 0.048, p = 0.014, p = 0.012, p = 0.012, p = 0.040 respectively). Following BS, decrease in FA values in the mentioned areas are detected. ADC values obtained from MCP are significantly lower in the post-BS period compared to pre-BS period (p = 0.018). There was a statistically significant difference between the pre-surgery and post-surgery AD values of SLF, SFOF, ILF, ALIC, EC, CST, and MCP (p = 0.001, p = 0.022, p = 0.001, p = 0.011, p = 0.001, p = 0.000, p = 0.000, respectively). Following the BS, AD values of the SLF, SFOF, ILF, ALIC, EC, CST, and MCP are decreased. RD values measured from GCC are significantly lower in the post-BS period compared to pre-BS period (p = 0.008). CONCLUSION: Our study supported the hypothesis of the BS-induced reversibility of the low-grade inflammation in WM tracts in the morbidly obese group following BS. Our DTI results may represent the subacute period findings of the reversal of low-grade inflammation after BS.

PURPOSE: To investigate whether the diffusion tensor imaging (DTI) parameters alterations in the in hypoxia-related neuroanatomical localizations in patients after COVID-19. Additionally, the relationship between DTI findings and the clinical severity of the disease is evaluated. METHODS: The patients with COVID-19 were classified into group 1 (total patients, n = 74), group 2 (outpatient, n = 46), and group 3 (inpatient, n = 28) and control (n = 52). Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were calculated from the bulbus, pons, thalamus, caudate nucleus, globus pallidum, putamen, and hippocampus. DTI parameters were compared between groups. Oxygen saturation, D dimer and lactate dehydrogenase (LDH) values associated with hypoxia were analyzed in inpatient group. Laboratory findings were correlated with ADC and FA values. RESULTS: Increased ADC values in the thalamus, bulbus and pons were found in group 1 compared to control. Increased FA values in the thalamus, bulbus, globus pallidum and putamen were detected in group 1 compared to control. The FA and ADC values obtained from putamen were higher in group 3 compared to group 2. There was a negative correlation between basal ganglia and hippocampus FA values and plasma LDH values. The ADC values obtained from caudate nucleus were positively correlated with plasma D Dimer values. CONCLUSION: ADC and FA changes may reveal hypoxia-related microstructural damage after COVID-19 infection. We speculated that the brainstem and basal ganglia can affected during the subacute period.

BACKGROUND: Various electrocardiographic (ECG) changes occur after subarachnoid hemorrhage (SAH). Prolonged QT and corrected QT (QTc) intervals are notable changes. QT, QTc, T peak-to-end T(p-e) intervals, and Tp-e/QTc ratio are used as ventricular arrhythmia indices. In recent publications, the cardiac electrophysiological balance index (ICEB), which provides more information than other ECG parameters (QT, QTc, etc.), is recommended in predicting the risk of ventricular arrhythmia. This study aims to assess ICEB in aneurysmal SAH patients. METHODS: The study included 50 patients diagnosed with aneurysmal SAH and 50 patients diagnosed with hypertension without end-organ damage as the control group. All patients' Fisher scores and Glasgow Coma Scale (GCS) scores were recorded. Both groups were given 12-lead ECGs. QT, QTc, Tp-e intervals, QRS duration, ICEB (QT/QRS), ICEBc (QTc/QRS), and T(p-e)/QTc values were calculated and analyzed between groups. RESULTS: Compared to the control group; QT (426,64 ± 14,62 vs. 348,84 ± 12,24 ms, p < 0,001), QTc (456,24 ± 28,84 vs. 392,48 ± 14,36 ms, p < 0,001), Tp-e (84,32 ± 3,46 vs. 70,12 ± 3,12, p < 0,001), Tp-e/QTc (0,185 ± 0,08 vs. 0,178 ± 0,02, p < 0,001), ICEB (4,53 ± 0,78 vs. 3,74 ± 0,28, p < 0,001) and ICEBc (4,86 ± 0,86 vs. 4,21 ± 0,24, p < 0,001) were significantly higher in patients with aneurysmal SAH. QT, QTc and Tp-e interval, Tp-e/QTc ratio, ICEB (QT/QRS) and ICEBc (QTc/QRS) were positively correlated with the Fisher score and were negatively correlated with the GCS. According to linear regression analyses, the ICEBc (QTc/QRS) found to be independently associated with the Fisher score. CONCLUSION: The values of the ICEB and ICEBc were significantly increased in patients with aneurysmal SAH. The severity of SAH was positively correlated with the ICEB and ICEBc. The ICEBc (QTc/QRS) independently associated with the Fisher score. This may that SAH suggest may predispose to malignant ventricular arrhythmias.

BACKGROUND: Vesical Imaging Reporting and Data System (VI-RADS) is a useful tool for evaluating muscle layer invasion of bladder cancer (BCa) on magnetic resonance imaging (MRI). PURPOSE: To evaluate the diagnostic performance of bladder MRI to detect the muscle layer invasion of BCa using VI-RADS score and quantitative MRI parameters. METHODS: Preoperative bladder MRI was performed in 73 BCa patients. Two observers independently evaluated the MR blinded to histopathological data and classified the tumors according to VI-RADS criteria. Moreover, the quantitative parameters (maximum tumor diameter; Dmax, tumor contact length; TCL, and tumor apparent diffusion coefficient; ADC values) were independently measured by observers. The diagnostic performance of the VI-RADS score and quantitative values were evaluated by using receiver operating characteristic (ROC) analysis. Interobserver agreement was evaluated using the weighted-kappa coefficient (κ). RESULTS: For the VI-RADS score, the AUC (area under the curve) was 0.968 and accuracy was 90.4% for Observer 1, and AUC was 0.953, accuracy was 89% for Observer 2. The AUC of TCL, TCL/DMax, and ADC values was 0.918, 0.675, and 0.832. In patients with a VI-RADS score ≥ 3, when a threshold value of TCL > 19.5 mm is used as complementary to the VI-RADS score, the accuracy of MRI for Observer-1 increases 100% and 97.26% for Observer-2. There was a good-excellent agreement between the observers in assessing the VI-RADS scores and quantitative parameters. CONCLUSION: Evaluation of bladder MRI using both VI-RADS criteria and TCL is successful and highly reproducible for detecting muscle layer invasion in patients with BCa.

OBJECTIVE: Fibroblast growth factor 23 (FGF-23) is a phosphorus-regulating hormone and plays a role in the pathogenesis of myocardial hypertrophy. The aim of this study was to evaluate the association of FGF-23 levels with echocardiographic parameters and insulin resistance (IR) in patients with gestational diabetes. SUBJECTS AND METHODS: Fifty-four pregnant patients with gestational diabetes mellitus (GDM) (age, 31.12 ± 5.72 years) and 33 healthy pregnant women (age, 29.51 ± 4.92 years) were involved in the study. Fasting insulin, fasting plasma glucose (FPG), lipid profile, oral glucose tolerance test (OGTT), FGF23, echocardiographic parameters, and carotid artery intima-media thickness (CIMT) were evaluated in the two groups. RESULTS: The two groups were not significantly different in age, sex, body mass index, lipid profile, or blood pressure. Insulin, homeostatic model assessment-insulin resistance (HOMA-IR), FGF-23 levels, CIMT, left ventricular (LV) mass, LV mass index and myocardial performance index (MPI) were significantly higher in the GDM group. HOMA-IR was positively correlated with FGF-23, and insulin was positively correlated with FGF-23. Additionally, FGF-23 was positively correlated with CIMT, LV mass index, and MPI. CONCLUSION: Our findings suggest that monitoring serum FGF-23 may be useful as a non-invasive indicator of subclinical atherosclerosis in patients with GDM.

Thiamine is a major vitamin that acts as a cofactor in energy metabolism in all organisms, as well as in lipid and amino acid metabolisms, and is associated with many diseases. It is known that glucose starvation decreases the intracellular thiamine pool while increasing oxidative stress tolerance. Earlier, in whole genome analysis, we detected major differences in the expression of genes related to thiamine pathway against oxidative stress in Schizosaccharomyces pombe. We investigated the effects of oxidative stress and glucose repression to thiamine pathway in S. pombe by comparing some genes encoding key enzymes of each related pathway at the transcription level. In the present study, we found that the expression of genes related to thiamine biosynthesis and transport (thi2, thi3, and pho1) increased in wild type and ird11 cells grown in thiamine-rich media under oxidative stress induced by H2O2. Based on our findings, we suggested that there might be an important effect of oxidative stress on thiamine biosynthesis and transport.
RESUMO
OBJECTIVE: In Turkey, a type of smokeless tobacco called Maras powder (MP) is widely used in the south-eastern region. Smokeless tobacco is found in preparations for chewing and for absorption by the nasal and oral mucosae. The purpose of this study was to investigate whether MP damages intra- and inter-atrial conduction delay and left atrial (LA) mechanical function as much as cigarette smoking. METHOD: A total of 150 chronic MP users (50 males, 32.5 ± 5.4 years), smokers (50 males, 32.1 ± 6.0 years) and controls (50 males, 30.1 ± 5.8 years) were included in the study. LA volumes were measured echocardiographically according to the biplane area-length method. Atrial electromechanical coupling was measured with tissue Doppler imaging and LA mechanical function parameters were calculated. RESULTS: The LA passive emptying fraction was significantly decreased and LA active emptying volume (LAAEV) was significantly increased in the MP group (p = 0.012 and p = 0.024, respectively), and the LA active emptying fraction (LAAEF) was significantly increased in the smokers (p = 0.003). There was a positive correlation between the amount of MP used and smoking (pack years) with LAAEV and LAAEF (r = 0.26, p = 0.009 and r = 0.25, p = 0.013, respectively). Lateral atrial electromechanical intervals (PA) were significantly higher in MP users, and the septal mitral PA was statistically higher in the smokers (p = 0.05 and p = 0.04, respectively). CONCLUSION: We suggest that atrial electromechanical coupling intervals were prolonged and LA mechanical function was impaired in MP users and smokers, but there was no significant difference between the MP users and smokers. These findings may be markers of subclinical cardiac involvement and tendency for atrial fibrillation.

BACKGROUND: The prevalence of allergic rhinitis and other allergies has risen worldwide. Dietary habits are considered to be among the potential risk factors. The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with dietary habits and other risk factors among 6 to 7-year-old Turkish schoolchildren. METHODS: In this cross-sectional study, a total of 11483 children aged 6-7 years were surveyed. The prevalence of symptoms of allergic rhinitis was assessed using the ISAAC protocol. Dietary information was collected using a food frequency questionnaire. RESULTS: Of them, 9875 (50.7% M 49.3% F) questionnaires were appropriately completed. The prevalence rates of lifetime rhinitis, current rhinitis, current rhinoconjunctivitis and physician-diagnosed allergic rhinitis, were 44.3%, 29.2%, 8.5% and 8.1%, respectively. Consumption of rice, and cereals ≥3 times per week showed protective effect on physician-diagnosed allergic rhinitis (aOR = 0.53, 95% CI = 0.32-0.87 and aOR = 0.58, 95% CI = 0.36-0.92). Eating pasta, and chocolates ≥3 times per week showed protective effect on current rhinoconjunctivitis (aOR = 0.45, 95% CI = 0.25-0.79 and aOR = 0.50, 95% CI = 0.29-0.86). Eating lollipops, candies and animal fats ≥3 times per week was positively associated with current rhinoconjunctivitis (aOR = 1.47, 95% CI = 1.00-2.17 and aOR = 2.25, 95% CI = 1.11-4.56). Protective effect of the Mediterranean diet was not significant. CONCLUSIONS: Frequent consumption of cereals, rice, pasta and chocolates may have beneficial effect on symptoms of rhinoconjunctivitis. Although dietary habits may affect the prevalence of symptoms of current rhinoconjunctivitis, the Mediterranean diet alone may not be protective against rhinoconjunctivitis.

The aim of this study was to evaluate the prevalence of allergic rhinitis and its relationship with various risk factors in 6-7-year-old children living in Istanbul. A total of 11,483 children aged 6-7 years in 75 primary schools from all districts of Istanbul were surveyed. Prevalence of symptoms of allergic rhinitis was assessed using a translated version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Of them, 9,875 (50.7% M, 49.3% F) questionnaires were appropriately completed by the parents. The prevalence rates of lifetime, current and physician-diagnosed allergic rhinitis were 44.3%, 29.2% and 8.1%, respectively. There was nearly a two-fold variation in the prevalence rates of rhinitis between the districts of Istanbul. Frequent paracetamol and antibiotic use in the first year of life, history of frequent upper respiratory tract infections, adenotonsillectomy, breastfeeding less than six months, dog at home or perianal redness in the first year of life, and frequent trucks passing near the home were independent risk factors.

BACKGROUND: This study was performed to evaluate the time trends in prevalence of asthma and related factors in Denizli, Turkey. METHODS: Two cross-sectional surveys were performed, 6 years apart (2002 and 2008) using the ISAAC protocol, in the 13-14 age groups and comparisons were made between the results. RESULTS: Lifetime prevalence of wheeze, 12 month prevalence of wheeze, and the prevalence of wheeze after exercise in the previous 12 months were significantly increased respectively from 10.2% to 13.4% (POR = 1.37, 95%CI = 1.18-1.58, p < 0.001), from 5.0% to 6.2% (POR = 1.26, 95%CI = 1.02-1.55, p = 0.016) and from 9% to 10.2% (POR = 1.15, 95%CI = 0.98-1.35, p = 0.046) in 2008 study. Doctor diagnosed asthma prevalence also increased significantly from 2.1% to 12.9 (POR = 6.80, 95%CI = 5.22-8.85, p < 0.001). Prevalence of sleep disturbed by wheeze in the last 12 months; but, never woken with wheezing (POR = 1.62, 95%CI = 1.26-2.09, p = < 0.001) and less than one night per week (POR = 1.58, 95%CI = 1.06-2.36, p = 0.013) were significantly increased in 2008 study. Severe attacks of wheeze limiting speech in the last year was increased from 1.3% to 2.2% (POR = 1.67, 95%CI = 1.14-2.43, p = 0.004). The number of wheeze attacks in the previous 12 months was increased significantly for 4-to-12 attacks (POR = 1.54, 95%CI = 1.03-2.32, p = 0.02) in 2008 study. However, prevalence of waking with cough in the last 12 months did not change. While history of family atopy and domestic animal at home were found as significant risk factors for asthma in 2002 study, male gender, history of family atopy and stuffed toys were found significant in 2008. CONCLUSIONS: The prevalence of asthma symptoms were increased in Denizli. History of family atopy, male gender and stuffed toys were important risk factors for asthma in 2008.

Atopic eczema (AE) is the most common childhood inflammatory skin condition. The aim of this study was to evaluate the prevalence of AE and its relation to various risk factors. In a cross-sectional study, 9,991 children ages 13 to 14 years in 61 primary schools in 32 districts of Istanbul were evaluated. The prevalence of AE and associated symptoms was assessed using the International Study of Asthma and Allergies in Childhood protocol. The relationship between risk factors and AE was evaluated using multivariate logistic regression analysis. Ten thousand nine hundred eighty-four questionnaires were distributed to 13- and 14-year-old children in 61 schools in 32 districts of Istanbul, 9,991 of which were suitable for analysis, for an overall response rate of 91.7%. There were 4,746 boys (47.9%) and 5,166 girls (52.1%) (M/F ratio 0.920). The rates of itchy rash ever, 12-month itchy rash, and doctor-diagnosed AE ever were 18.2%, 12.0%, and 2.8%, respectively. The difference between rates for itchy rash ever, 12-month itchy rash and doctor-diagnosed AE was high (12.8-31.3, 5.8-24.8, and 0-17.2, respectively) between the districts of Istanbul. Female sex, AE family history, watching television more than 5 hours a day, region of the district, and tonsillectomy history were found to be significantly associated with doctor-diagnosed AE at p < 0.05 in multivariate analysis. This study found a low prevalence of doctor-diagnosed AE and related symptoms in Istanbul. Several risk factors were found to be associated with doctor-diagnosed AE.

OBJECTIVE: Familial Mediterranean fever (FMF) is an autosomal recessive autoimmune disease, presenting with the attacks of fever and inflammation of serous membranes. One of the leading causes of death in autoimmune rheumatologic diseases is cardiovascular events. The purpose of this study is to evaluate the effects of FMF on the autonomic nerve and cardiovascular systems by measuring the indices of heart rate variability (HRV). MATERIAL AND METHODS: Thirty FMF patients and the same number of healthy volunteers were enrolled to the study. Standard deviation of all R-R intervals (SDNN), the square root of the sum of the square of the differences between successive R-R intervals (RMSSD), standard deviation of 5-minute mean values of R-R interval (SDANN), low frequency (LF), and high frequency (HF) were measured. RESULTS: Time domain indices (SDNN, SDANN, and RMSSD) were: 124.67±40.79, 129.87±36.43 (p=0.605); 11.43±38.41, 11.23±38.98 (p=0.984); and 33.43±17.39, 38.17±12.8 (p=0.235) for FMF patients and controls, respectively, and similar in both groups. Frequency domain indices (HF, LF, and LF/HF) were: 290.41±290.25, 322.20±222.54 (p=0.639); 596.16±334.07, 805.80±471.00 (p=0.051); and 3.57±2.57, 3.05±1.40 (p=0.338) for FMF patients and controls, respectively, and similar in both groups. CONCLUSION: The HRV parameters were similar in both groups. However, studies including larger populations and using different methods are required to clarify if autonomic dysfunction exists in patients with FMF.
RESUMO
OBJECTIVES: The aims of this study were to evaluate atrial electromechanical delay, inflammation, and oxidative stress parameters, along with to investigate clinical and laboratory characteristics affecting atrial electromechanical delay in patients with chronic obstructive pulmonary disease (COPD). METHODS: Forty-three patients with COPD (60.5 ± 9.9 years) and 50 healthy controls (59.6 ± 7.1 years) were included in the study. Atrial electromechanical delay intervals were measured from lateral mitral annulus corrected PA (cPA lateral) and lateral tricuspid annulus (cPA tricuspid) using tissue Doppler imaging (TDI), and corrected for heart rate. Left and right ventricles functions were examined using conventional and TDI. Plasma levels of high-sensitive C-reactive protein (hsCRP) and oxidative stress parameters were also measured. Factors associated with atrial electromechanical delay were evaluated by stepwise multiple regression analysis. RESULTS: Corrected PA lateral and cPA tricuspid were significantly higher in patients with COPD (69.8 ± 10.4 vs. 62.2 ± 8.9 msec, P < 0.001 and 45.4 ± 10.2 vs. 33.5 ± 5.1 msec, P < 0.001, respectively). Plasma levels of hsCRP and malondialdehyde, an indicator of oxidative stress, were increased in patient's group (15.7 ± 31.7 vs. 4.8 ± 4.7 mg/L, P = 0.01 and 17.1 ± 10.3 vs. 11.6 ± 7.9 nmol/L, P = 0.005, respectively). cPA lateral is independently related to lateral Em /Am ratio (ß = -0.29, P = 0.004) and forced expiratory volume in 1st second/forced vital capacity (FEV1 /FVC) ratio (ß = -0.24, P = 0.02). cPA tricuspid is independently related to only FEV1 /FVC ratio (ß = -0.51, P < 0.001). CONCLUSIONS: This study shows that atrial electromechanical delay intervals are prolonged in patients with COPD. Prolongation of atrial electromechanical delay measured from lateral tricuspid annulus was independently related with FEV1 /FVC ratio in these patients.
