Associations of non-HDL-C and triglyceride/HDL-C ratio with coronary plaque burden and plaque characteristics in young adults.

Coronary artery disease (CAD) is uncommon in young adult patients. However, these patients have different risk factor profiles and high-risk coronary plaques are more common. The aim of this study was to examine the relations between the coronary plaque burden, plaque composition, serum non-high-density lipoprotein cholesterol (non-HDL-C) levels, and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio in young adults. We analyzed a total of 551 patients under age 45 who had undergone coronary computed tomography angiography (CCTA). Coronary plaque characteristics were analyzed using CCTA. Multivariate linear regression analysis was used to assess the predictors of non-calcified plaque (NCB) and calcified plaque (CB) burdens. Serum non-HDL-C levels and TG/HDL-C ratio were higher in the coronary atherosclerosis patient group. Serum non-HDL-C levels and the TG/HDL-C ratio were higher in the obstructive CAD patient group. The plaque burden was positively correlated with non-HDL-C (r = 0.30; p < 0.001), and TG/HDL-C ratio (r = 0.18; p < 0.001).  NCB was positively correlated with age, gender, smoking status, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, serum triglycerides, hbA1c, non-HDL-C, and TG/HDL-C ratio. Non-HDL-C (ß coefficient = 0.13; p = 0.023) and TG/HDL-C ratio (ß = 0.10;  p = 0.042) were independent predictors of NCB. Serum non-HDL-C levels and TG/HDL-C were significantly associated with the presence and burden of coronary plaques. Serum non-HDL-C and TG/HDL-C ratios were independently associated with NCB, suggesting their use as easy-to-compute markers for identifying high-risk groups in young adults.

Headache in idiopathic/genetic epilepsy: Cluster analysis in a large cohort.

OBJECTIVE: The link between headache and epilepsy is more prominent in patients with idiopathic/genetic epilepsy (I/GE). We aimed to investigate the prevalence of headache and to cluster patients with regard to their headache and epilepsy features. METHODS: Patients aged 6-40 years, with a definite diagnosis of I/GE, were consecutively enrolled. The patients were interviewed using standardized epilepsy and headache questionnaires, and their headache characteristics were investigated by experts in headache. Demographic and clinical variables were analyzed, and patients were clustered according to their epilepsy and headache characteristics using an unsupervised K-means algorithm. RESULTS: Among 809 patients, 508 (62.8%) reported having any type of headache; 87.4% had interictal headache, and 41.2% had migraine. Cluster analysis revealed two distinct groups for both adults and children/adolescents. In adults, subjects having a family history of headache, ≥5 headache attacks, duration of headache ≥ 24 months, headaches lasting ≥1 h, and visual analog scale scores > 5 were grouped in one cluster, and subjects with juvenile myoclonic epilepsy (JME), myoclonic seizures, and generalized tonic-clonic seizures (GTCS) were clustered in this group (Cluster 1). Self-limited epilepsy with centrotemporal spikes and epilepsy with GTCS alone were clustered in Cluster 2 with the opposite characteristics. For children/adolescents, the same features as in adult Cluster 1 were clustered in a separate group, except for the presence of JME syndrome and GTCS alone as a seizure type. Focal seizures were clustered in another group with the opposite characteristics. In the entire group, the model revealed an additional cluster, including patients with the syndrome of GTCS alone (50.51%), with ≥5 attacks, headache lasting >4 h, and throbbing headache; 65.66% of patients had a family history of headache in this third cluster (n = 99). SIGNIFICANCE: Patients with I/GE can be clustered into distinct groups according to headache features along with seizures. Our findings may help in management and planning for future studies.

Evaluation of coronary flow with computed tomography derived FFR: Advantages and pitfalls.

Coronary computed tomographic angiography (CCTA) is an excellent noninvasive, anatomic imaging modality for direct visualization of coronary arteries and for the assessment of coronary artery disease (CAD). CCTA has high sensitivity and high negative-predictive value for the identification of obstructive CAD; however, its specificity and positive-predictive value are low. After more than a decade of using CCTA to assess the anatomic severity of CAD, novel modalities of obtaining functional information from CCTA have been developed to increase its specificity and accuracy. These modalities use computational fluid dynamics to calculate fractional flow reserve (FFR) from CCTA datasets. Computed tomography-derived FFR (FFRCT) predicts virtual hyperemia for computation. Therefore, no additional image acquisition, medication, radiation exposure, or pharmacologic stress agent during CCTA examination are necessary for the calculation of FFRCT. Multiple, prospective single or multicenter studies have shown that FFRCT is poised to become a gate-keeper for catheterization laboratory. In this article, we aim to review the principles, diagnostic accuracy, advantages, limitations, and pitfalls of FFRCT.

Evaluation of the morphological and clinical features of left anterior descending myocardial bridging with multi-detector computed tomography.

AIM: The aim of the study was to assess the incidence, localization, depth, length of myocardial bridging (MB) with left anterior descending (LAD), systolic compression ratio, atherosclerotic plaque localization and degree of stenosis by 256-slice multi-detector computed tomography (MDCT). MATERIAL AND METHODS: Computed tomography (CT) scans from a total of 3947 patients who underwent MDCT were reviewed retrospectively for LAD MB. A diastolic and systolic dataset with the best image quality was selected. Myocardial bridge was defined as a coronary artery with an intra-myocardial course. Myocardial bridging was divided into "deep" or "superficial". The length and depth of the bridging segment were calculated. For each bridging segment, the presence of atherosclerosis was saved in a 2-cm-long segment proximal to the entry of the bridging segment. The degree of stenosis made by atherosclerotic plaques was determined. RESULTS: LAD myocardial bridging was detected in 410 (10.4%) patients. Among these, 97 (23.7%) patients had a deep and 313 (76.3%) patients had a superficial course. The mean LAD MB length was 20.28 ±9.63 mm and the depth was 1.72 ±1.11 mm. The systolic and diastolic mean diameter difference was 0.193 mm and the average compression ratio was 9.44%. Atherosclerotic plaques were found in 167 (40.7%) of 410 LAD MB. Atherosclerotic plaques were found in 50.5% of deep MB and 37.7% of superficial MB. CONCLUSIONS: 256-slice MDCT coronary angiography has a high sensitivity to show myocardial bridging in LAD localization, to determine length, depth, compression ratio, atherosclerotic plaque localization and degree of stenosis.

Stroke prevalence among the Turkish population in a rural area of Istanbul: A community-based study.

BACKGROUND: The population-based information on the prevalence of stroke from rural areas of Middle East countries including Turkey is unknown. Our aim is to evaluate the prevalence of stroke in those ⩾18 years in the Turkish population in a rural area of Istanbul. METHODS: A cross-sectional door-to-door study was conducted in a rural area of Istanbul between 1 March and 30 March 2013. A research protocol recommended by World Health Organization for developing countries was used. Each screening teams consisted of one neurologist, one local nurse, and five surveyors. Teams were trained about the survey and questionnaire. The patients, who claimed to have suffered a stroke, were examined, and the diagnosis was confirmed by a neurologist on site. The findings and medical records were documented. RESULTS: In total, 2906 people ⩾18 years were screened. 50 stroke cases were detected. 80% of those were found to have had an ischemic stroke, 14% of those were hemorrhagic cases, and 6% of those had an unclassified stroke type. The overall prevalence rate in those ⩾ 18 years was 1.7%. The male/female ratio was 0.92. Young (<45) stroke prevalence was found to be 0.6%. CONCLUSION: This study was the first of its kind to show the stroke prevalence among Turkish population ⩾ 18 years in a rural area of Istanbul. When compared to other studies which investigate people ⩾45 years from Turkey, the result (in the same age group) was moderate high. The male/female ratio was low compared to many other studies.

Thickness of carotid intima and epicardial fat in rosacea: a cross-sectional study

Abstract: Background: Rosacea is a chronic facial skin disease associated with excessive inflammatory response to various triggers. Although some studies have supported the increased risk of cardiovascular diseases in rosacea, it has not been completely accepted. Objective: We aimed to investigate epicardial fat thickness and carotid intima-media thickness as cardiovascular risk predictors in rosacea patients. Methods: We conducted a cross-sectional study including 40 rosacea patients and 40 controls. Demographic data, epicardial fat thickness, carotid intima-media thickness, lipid parameters, biochemical parameters, presence of insulin resistance, and presence of metabolic syndrome of the participants were recorded. Results: Forty rosacea patients (31 female and 9 male) and 40 controls (30 female and 10 male) were enrolled in the study. Rosacea patients had significantly higher epicardial fat thickness and carotid intima-media thickness volumes than controls (P<0.001). In the multivariate logistic regression analysis, epicardial fat thickness was independently related to presence of rosacea (P<0.001, OR=13.31). In the multiple linear regression analysis, the epicardial fat thickness was independently associated with rosacea (β= 0.47, P<0.001), carotid intima-media thickness (β= 0.36, P<0.001), and systolic blood pressure (β=0.19, P=0.015) and the carotid intima-media thickness was independently associated with epicardial fat thickness (β= 0.6, P<0.001). The epicardial fat thickness levels were correlated with carotid intima-media thickness (r=0.63, P<0.001), LDL (r=0.23, P=0.037), systolic blood pressure (r=0.45, P<0.001), and diastolic blood pressure levels (r=0.37, P=0.001). The carotid intima-media thickness levels were correlated with epicardial fat thickness (r=0.63, P<0.001), systolic blood pressure (r=0.04, P<0.001), and diastolic blood pressure levels (r=0.27, P=0.016). Study limitations: The small number of participants. Conclusions: Examination and follow-up of rosacea patients for cardiovascular diseases may be recommended practices.

The Effects of Cognitive Rehabilitation on Relapsing Remitting Multiple Sclerosis Patients.

INTRODUCTION: The aims of this study were to determine the severity of cognitive impairment with Brief Repeatable Battery Neuropsychology (BRB-N) and to show the benefits of cognitive rehabilitation programs to develop coping strategies for the retardation of cognitive losses in relapsing remitting multiple sclerosis (RRMS) patients. METHODS: The cognitive screening with BRB-N was performed in RRMS patients who had applied to the MS outpatient clinic of Bakirköy Psychiatric and Neurological Diseases Hospital, had an Expanded Disability Status Scale (EDSS) score between 1.0 and 5.5, and had no other cognitive disease or used drugs that effected the cognitive status. Thirty two patients with cognitive impairment underwent consecutive computer-assisted cognitive rehabilitation program once a week for 8 weeks conducted by psychologists. The effects of the program were evaluated with the tests repeated every 4 weeks. RESULTS: The mean age of the patients was 36.09±7.19 years. Their initial and control test scores were found to be paced auditory serial addition test (PASAT) 29.21±17.97; 42.43±15.43, Selective Reminding Test-Total Learning (SRT-TL) 8.03±2.36; 10.09±1.77, Selective Reminding Test-Long-term Memory (SRT-DR) 6.72±2.74; 9±2.29, Spatial Recall Test-Total Learning (SPART-TL) 4.72±2.02; 4.22±1.74, Spatial Recall Test-Long-term Memory (SPART-DR) 5.94±2.54; 5.16±2.23, Symbol Digit Modalities Test (SDMT) 40.44±17.04; 46.47±17.94, Word Fluency Test (WLG) 32.88±9.87; 40.44±9.95 respectively. There was no significant statistical difference between Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ) and SPART values of preface, 1st control and 2nd control (p>0.05). There was significant statistical difference between PASAT, WLG, SDMT, SRT-TL, SRT-DR values of Preface, 1st control, and 2nd control (p=0.0001). CONCLUSION: It was determined that on distinctive improvement on sustaining attention, working memory and information processing speed, and verbal fluency and verbal learning with cognitive rehabilitation, no changes were observed on visuospatial learning. This approach is hopeful and further comprehensive studies are needed.

Effect of statins on endothelial function in patients with acute coronary syndrome: a prospective study using adhesion molecules and flow-mediated dilatation.

BACKGROUND: Accumulating evidence suggests that inflammatory mechanisms play a central role in the development, progression and outcome of atherosclerosis. Recent evidence suggests that statins improve anti-inflammatory, anti-thrombotic and endothelial functions, along with their lipid-decreasing effects. We examined the effect of statins on endothelial function using biochemical markers of endothelial dysfunction and brachial artery flow-mediated dilatation (FMD). METHODS: Thirty male patients presenting with acute coronary syndrome (ACS) and 26 age-matched healthy control subjects aged 40 - 60 years who were not on any medication were enrolled in the study. The patient group was started on atorvastatin (40 mg/day) without consideration of their low-density lipoprotein (LDL)-cholesterol levels. Endothelin, sICAM and E-selectin from stored serum samples were measured using commercially available enzyme-linked immunosorbant assays (ELISAs). Endothelial function was assessed using brachial artery FMD. RESULTS: Prior to statin treatment, E-selectin, sICAM and endothelin levels, endothelial dysfunction markers, were 99.74 ± 34.67 ng/mL, 568.8 ± 149.0 ng/mL and 0.62 ± 0.33 fmol/mL, respectively in the patient group. E-selectin and sICAM levels were significantly higher in the patients than in the control subjects (P < 0.001); however, endothelin levels were not significantly different between groups. Statin treatment significantly reduced E-selectin and sICAM levels (P < 0.001); however, the decrease in endothelin levels was not statistically significant. %FMD values were significantly increased after statin treatment (P = 0.005), and levels of C-reactive protein (CRP), an inflammation marker, were significantly reduced. CONCLUSION: Our results indicate that statins play an important role in treatment endothelial dysfunction by reducing adhesion of inflammatory cells.

Improvement of dilated cardiomyopathy with methylprednisolone in a patient with multiple fibrosclerosis.

Multifocal fibrosclerosis is a rare syndrome of unknown cause that is characterized by fibrosis involving multiple organ systems. Definitive diagnosis can only be made based on biopsy findings. In this case, the biopsy specimen of the patient demonstrates pulmonary hyalinated granuloma or sclerosing mediastinitis. There are few reports of multiple fibrosclerosis with heart failure. Here, we reported a case of retroperitoneal fibrosis with massive mediastinal involvement extending to pleura and pericardium causing pleuro- pericardial effusion with dilated cardiomyopathy. Systolic dysfunction was improved and pericardial effusion disappeared with methylprednisolone treatment.

A prospective study on the utility of diffusion-weighted and quantitative chemical-shift magnetic resonance imaging in the distinction of adrenal adenomas and metastases.

OBJECTIVE: The purpose of this study was to assess the utility of diffusion-weighted and quantitative chemical-shift magnetic resonance imaging in the differentiation of adrenal adenomas and metastases. METHODS: One hundred eight patients (45 men and 63 women; mean age, 57 years) with 126 adrenal masses were prospectively evaluated by magnetic resonance imaging in this study. Signal intensity and apparent diffusion coefficient (ADC) measurements were performed on axial in- and opposed-phase T1-weighted gradient-echo images and on diffusion-weighted images, respectively. Adrenal signal intensity index (ASII), adrenal-to-spleen chemical-shift ratio (ASR), and ADC values were assessed separately. The threshold values of more than 16.5% for ASII and less than 0.71 for ASR were regarded as highly suggestive of adenoma diagnosis. We also investigated whether a cutoff value for ADC could be found in distinguishing adenomas from metastases. Final diagnoses of adrenal lesions were based on follow-up imaging, histopathologic proof, and adrenal washout study. Apparent diffusion coefficient values of adenomas and metastases were compared by using the Student t test, and ASII and ASR values of the lesions were compared by using the Mann-Whitney U test, and a P < 0.05 was accepted as statistically significant. Receiver operating characteristic curve analysis and sensitivity, specificity, positive and negative predictive values, and overall accuracies were calculated. RESULTS: Final analysis yielded 96 adenomas and 30 metastases. With the commonly used 16.5% threshold value for ASII, we obtained a 94.8% sensitivity, 93.3% specificity, 84.8% positive predictive value, and 97.8% negative predictive value. The overall accuracy was found as 94.4%. When we applied a 0.71 threshold value for ASR, it yielded a 91.7% sensitivity, 100% specificity, 78.9% positive predictive value, and a 100% negative predictive value. The overall accuracy was 93.6%. The mean ADC values were found to be 1.35 ± 0.19 × 10⁻³ mm²/s and 1.32 ± 0.34 × 10⁻³ mm²/s for adenomas and metastases, respectively. The difference between the groups with these ADC values was not statistically significant (P = 0.673). The receiver operating characteristic analysis could not determine a clear cutoff value for the differentiation of adenomas from metastases. CONCLUSIONS: We can advocate that a chemical-shift magnetic resonance imaging using quantitative parameters (ie, ASII and ASR formulas) has an important role in the distinction of adenomas from metastases. These 2 techniques seem to provide close sensitivity, specificity, and accuracy levels. But diffusion-weighted imaging using quantitative ADC measurements is not of value in this differential diagnosis because of the substantial overlapping of ADC values between adenomas and metastases.
