    Complex mechanisms including genetic factors have been proposed in the pathogenesis of primary hypertension (HT). Micro RNAs (miRNAs) are single-stranded RNA molecules that are not converted into protein products. However, it has been established that genes regulate conversion into protein products. The primary aim of this study was to investigate the roles of miRNA 4516, miRNA 145, miRNA 24, and miRNA 181a in the pathogenesis of HT. The secondary aim was to investigate the relation between these miRNAs and renin, aldosterone, norepinephrine, renalase, and NOS. Fifty-two hypertensive and 51 control normotensive individuals under observation in the Cappadocia cohort were included in the study. miRNA 4516, miRNA 181a, miRNA 24, and miRNA 145 levels were measured using the ddPCR method. miRNA 4516 and norepinephrine levels were significantly higher in the HT group (P < .005 for both), while miRNA 145 levels were significantly lower (<.05). miRNA 4516 up-regulation (P < .05) and miRNA 145 down-regulation (P < .05) were identified as independent predictors of HT. Renalase exhibited negative correlation with miRNA 4516 and positive correlation with miRNA 145 in the patient and control group. In addition, negative correlation was present between miRNA 24 and NE and NOS and between miRNA 181a and NOS in the patient group. Our study identified, for the first time in the literature, miRNA 4516 up-regulation and miRNA 145 down-regulation as independent determinants of HT. Further studies performed in the light of our findings may lead to a better understanding of the pathogenesis and new therapeutic possibilities.WoSScopu

    The Effect Of Intermittent Fasting On Blood Pressure Variability In Patients With Newly Diagnosed Hypertension Or Prehypertension

    Intermittent fasting is a phenomenon which can be observed in most humans. The effect of intermittent fasting on blood pressure variability (BPV) has not previously been investigated. The purpose of this study was to assess the effect of fasting on blood pressure (BP) (with office, home, central, and ambulatory blood pressure monitoring [ABPM]) and on BPV. Sixty individuals were included in the study. Office, home, ABPM, and central BP measurements were performed before and during intermittent fasting. Standard deviation and coefficient variation were used for office and home BPV measurement, while the smoothness index was used to calculate ABPM variability. Patients' BP and BPV values before and during intermittent fasting were then compared. Intermittent fasting resulted in a significant decrease in office BP values and ABPM measurements but caused no significant change in home and central BP measurements. Twenty-four hour urinary sodium excretion decreased. Smoothness values obtained from ABPM measurements were low; in other words, BPV was greater. BPV was higher in patients who woke up to eat before sunrise, but BPV was low in patients with high body mass index. Intermittent fasting produced a significant decrease in BP values in terms of office and ABPM measurements in this study but caused no significant change in central BP and home measurements. We also identified an increase in BPV during intermittent fasting, particularly in patients who rose before sunrise. (C) 2017 American Society of Hypertension. All rights reserved.WoSScopu

    Home sphygmomanometers can help in the control of blood pressure: a nationwide field survey

    No full text
    Home blood pressure monitoring (HBPM), which integrates patients into their treatment program, is a self-management tool. The prevalence of home sphygmomanometer ownership and patient compliance with HBPM guidelines are not well known, especially in developing and underdeveloped countries. The aims of this study were to measure the prevalence of home sphygmomanometer ownership among hypertensive subjects through a nationwide field survey (PatenT2), to investigate the validation of sphygmomanometers and consistency of the user arm circumference and cuff size of the upper-arm device owned, as well as to compare blood pressure (BP) readings between hypertensive subjects who have or do not have a sphygmomanometer. Sample selection was based on a multistratified proportional sampling procedure to select a nationally representative sample of the adult population (n = 5437). Of 1650 hypertensive subjects, 332 (20.1\%) owned a device, but the percentage of patients who owned a sphygmomanometer was 28.8\% among patients who were aware of their hypertension (260/902). The usage of wrist devices and nonvalidated devices is common, and selection of an appropriate cuff size is ignored. Linear-regression analysis showed that owning a BP monitor is associated with decreases of 3.7 mmHg and 2.8 mmHg for systolic and diastolic BPs, respectively. Many patients do not own a sphygmomanometer. The decrease of systolic and diastolic BPs among BP monitor owners is a striking finding. The implementation of a hypertension care program consisting of sphygmomanometer reimbursement and training of patients in its use for HBPM might be costeffective

    Dietary Sources of High Sodium Intake in Turkey: SALTURK II

    Previous research has shown daily salt intakes in Turkey to be far above the recommended limits. Knowing the sources of dietary salt could form a basis for preventive strategies aimed towards salt reduction. This study aimed to investigate dietary sources of salt in Turkey. A sub-group (n = 657) was selected from the PatenT2 study population, which represented the urban and rural areas of 4 major cities (Ankara, Istanbul, Izmir, and Konya). A questionnaire inquiring about sociodemographic characteristics, medical histories, detailed histories of diet, and salt consumption was completed. Participants were asked to collect a 24-h urine sample and to record their food intake (dietary recall) on the same day. Of 925 participants selected, 657 (71\%) provided accurate 24-h urine collections, based on creatinine excretion data. The mean daily 24-h urinary sodium excretion was 252.0 +/- 92.2 mmol/day, equal to daily salt intake of 14.8 +/- 5.4 g. Of the 657 participants with accurate 24-h urine collections, 464 (70\%) provided fully completed dietary recalls. Among these 464 participants, there was a significant difference between the 24-h urinary sodium excretion-based salt intake estimation (14.5 +/- 5.1 g/day) and the dietary recall-based salt intake estimation (12.0 +/- 7.0 g/day) (p < 0.001). On the other hand, a positive correlation was obtained between the dietary recall-based daily salt intake and 24-h urinary sodium excretion-based daily salt intake (r = 0.277, p < 0.001). Bread was the main source of salt (34\%) followed by salt added during cooking and preparing food before serving (30\%), salt from various processed foods (21\%), and salt added at the table during food consumption (11\%). Conclusively, this study confirmed a very high salt intake of the adult population in four major cities in Turkey. The present findings support the emerging salt reduction strategy in Turkey by promoting lower salt content in baked bread, and less salt use in habitual food preparation and during food consumption in the home

    Mitochondrial carrier homolog 1 (Mtch1) antibodies in neuro-Behcet's disease

    Efforts for the identification of diagnostic autoantibodies for neuro-Behcet's disease (NBD) have failed. Screening of NBD patients' sera with protein macroarray identified mitochondrial carrier homolog 1 (Mtch1), an apoptosis-related protein, as a potential autoantigen. ELISA studies showed serum Mtch1 antibodies in 68 of 144 BD patients with or without neurological involvement and in 4 of 168 controls corresponding to a sensitivity of 47.2% and specificity of 97.6%. Mtch1 antibody positive NBD patients had more attacks, increased disability and lower serum nucleosome levels. Mtch1 antibody might be involved in pathogenic mechanisms of NBD rather than being a coincidental byproduct of autoinflammation. (C) 2013 Elsevier B.V. All rights reserved
