Hypertension and nephrology

[Overview of a 10 years kidney biopsies data from the Nephrological and Blood Pressure Center Szeged]

[The authors retrospectively analyzed the data of kidney biopsies performed between 01/01/2007 and 31/12/2016 performed in the Center. During this period 452 biosies were performed. Mean age of patients was 48.7±15.0 years, of them, 43.5% were man and 56.5% women. The nephrotic syndrome was the most common (38.8%) clinical indications for a biopsy. The mos common histological diagnoses were the membranous nephropathy (16.7%), the IgA nephropathy (11.6%) and the FSGS (10.9%). The most common suggestions by nephrologists were the FSGS (17.4%), the membranous nephropathy (16.1%) and the IgA nephropathy (10.3%). These percentages of diabetic nephropathy were 7.5% and 12.2%. Minor complications not requiring any interventions occured in 98 cases (21.7%), major ones in 13 cases (2.9%). By the results FSGS seems to be overrated by nephrologists, but it is among the 3 most common histological findings. Diabetic nephropathy is a similarly excessive clinical diagnosis, sithence the histologically confirmed diagnoses are only a little more than half of it. Regular meetings of pathologists and nephrologists about clinical suggestions and real histological diagnoses may help to improve the ratio of more accurate suggestions.]

[Hyperuricemia in hypertension. Domestic experience based on the data of the Hungarian Hypertonia Register 2011., 2013., 2015. Part II.]

ALFÖLDI Sándor, PAKSY András, KÉKES Ede

[Asymptomatic hyperuricemia is frequent in hypertension and its prevalence is increasing. Authors studied the incidence of serum uric acid levels and its correlation with age, risk factors, anthropological, metabolic characteristics, blood pressure, blood pressure target, organ damage, age-related co-morbidity in 47,372 hypertensive patients (22,688 males, 24,694 women). In the second part of their analysis the prevalence of hyperuricemia was 13.8% in hypertensive men and 21.6% in women. The age, BMI, waist diameter, systolic and diastolic blood pressure and onset of hypertension, serum cholesterol, triglyceride, blood glucose and serum creatinine were slightly higher, but serum HDL cholesterol and eGFR were slightly lower in hyperuricemic hypertensive patients, independently of their gender. Among hypertension mediated organ damage ischemic and left ventricular hypertensive ECG alterations, mild chronic kidney disease and proteinuria, among hypertension associated diseases diabetes associated ischemic heart disease, chronic kidney disease associated diabetes and both ischemic and chronic kidney disease associated diabetes were significantly more frequent in hyperuricemic hypertensive patients.]

Relationship between Status Epilepticus Severity Score and etiology in adult NCSE patients

GENC Fatma, ERDAL Abidin, AKCA Gizem, KARACAY Ertan, GÖKSU Özaydın Eylem, KUTLU Gülnihal, GÖMCELI Bicer Yasemin

Purpose - Nonconvulsive status epilepticus (NCSE) is a heterogeneous, severe neurological disorder of different etiologies. In this study, the outcomes of NCSE episodes was assessed in a large series of adult patients. Our objective was to evaluate relationship between Status Epilepticus Severity Score (STESS) and etiology and the role of etiological factors on predicting the outcomes. Method - In this retrospective study, the medical records of 95 patients over 18 years of age who were diagnosed with NCSE between June 2011 and December 2015 were reviewed. Their treatment and follow-up for NCSE was performed at the Epilepsy Unit in Department of Neurology, Antalya Research and Training Hospital. Etiological factors thought to be responsible for NCSE episodes as well as the prognostic data were retrieved. The etiological factors were classified into three groups as those with a known history of epilepsy (Group 1), primary neurological disorder (Group 2), or systemic/unknown etiology (Group 3). STESS was retrospectively applied to patients. Results - There were 95 participants, 59 of whom were female. Group 1, Group 2, and Group 3 consisted of 11 (7 female), 54 (33 female), and 30 (19 female) patients, respectively. Of the 18 total deaths, 12 occurred in Group 2, and 6 in Group 3. The negative predictive value for a STESS score of ≤ 2 was 93.88% (+LR 2.05 95% CI: 1.44-2.9 and -LR 0.3 95% CI 0.10-0.84 ) in the overall study group. While the corresponding values for Group 1 (patients with epilepsy), Group 2 (patients with primary neurological disorder), and group 3 (patients with systemic or unknown etiology) were 100%, 92.59% (+LR 2.06 95%CI: 1.32-3.21 and -LR 0.28 95% CI 0.08-1.02 ) 83.33% (+LR 1.14 95%CI: 0.59-2.9 and -LR 0.80 95% CI 0.23-2.73). Conclusions - This study included the one of the largest patients series ever reported in whom STESS, a clinical scoring system proposed for use in patients with status epilepticus, has been implemented. Although STESS appeared to be quite useful for predicting a favorable outcome in NCSE patients with epilepsy and primary neurological disorders, its predictive value in patients with systemic or unknown etiology was lower. Further prospective studies including larger NCSE samples are warranted.

[Physical activity, physical function and exercise in chronic kidney disease]

NAGY Judit, APOR Péter, KISS István

[This review summarize the decreased physical activity and physical function of chronic kidney disease patients from the early stage of their renal disease; the favourable effects of exercise training on physical activity and function as well as on progression of chronic renal diseases. At the end, there is a recommendation for implementation of exercise in this renal patient population. The conclusion is that, on the basis of the evidences patients with chronic renal disease should be advised to increase their physical activity in all stages of their renal disea]

Can high uric acid levels be an independent risk factor for acute ischemic stroke due to large-artery atherosclerosis?

ACAR Türkan, ARAS Guzey Yesim, GÜL Sinem Sidika, ACAR Atılgan Bilgehan

Introduction - Uric acid is a molecule that is known to act as a natural antioxidant in acute oxidative stress conditions such as acute ischemic stroke (AIS). Although there are several studies on the prognostic value of serum uric acid (UA) level, especially the AIS, its importance in ischemic stroke is still controversial. Our aim in this study is to investigate whether the serum UA level is an indicative biomarker in the large-artery atherosclerosis in the AIS etiology. Material and method - Of the patients admitted to Sakarya University Training and Research Hospital Depart-ment of Neurology between January 2017 and November 2017, 91 hospitalized patients, who had AIS diagnosis and had their uric acid levels measured, were analyzed retrospectively. Patients with diabetes mellitus (DM), hypertension (HT), smoking habit, obesity, gout, hyperlipidemia (HL) and renal failure were excluded from the study. Patients were classified as anterior system and posterior system infarct. Then, patients were divided into two groups, one with internal carotid artery (ICA) > 50% stenosis and the other with ICA < 50% stenosis according to carotid-vertebral artery doppler USG examination performed for etiology. Serum UA, total bilirubin, direct bilirubin and indirect bilirubin levels of both groups were statistically compared. Results - In the comparison of serum UA values of ICA>50% stenosis and ICA<50% stenosis group of AIS patients, a statistically significant difference was found between the UA levels (p<0.000), but there was no difference between total bilirubin, direct bilirubin and indirect bilirubin values (p>0.05). Conclusion - High uric acid levels can be considered an independent, indicative risk factor for large-artery disease in AIS.

[Socialisation in the medical profession as reflected by students]

MOLNÁR Regina, MOLNÁR Péter

[INTRODUCTION - This article analyses the socialisation in the medical profession using complex approach, and taking Merton’s definition as a starting point. METHODS - Qualitative sociological, semistructured deep-interview method. RESULTS - The motivation of medical students in choosing their profession have not changed in the past years. The socialisational phases can clearly be observed during their training, these can serve as a basis for empirical observations. The role of classes related to behavioural studies is significant, while the opinion of the students about the teaching methods is diverse. Taking a family member as a model or work experience gained in medical fields is an advantage in the socialisational process. Temporal or partial leaving of the profession are new phenomena. CONCLUSION - Considering the characteristics of qualitative observational methods, the results of the present analysis may serve as a starting point for further empirical observations based on a representative model.]

[OPTIMAL ALIGNMENT®. NOVEL SOFTWARE PROCEDURE FOR 3D RECONSTRUCTION OF ELECTRONMICROSCOPIC SERIAL SECTIONS]

SIMON László, GARAB Sándor, NOSZEK Annamária, ELIZABETH Römmer, ZÁBORSZKY László

[3D reconstruction from electronmicroscopic (EM) serial sections substantially differs from modeling body parts by linking convoluted planes delivered by CT and NMR. Namely, variations both in relative X-Y position and rotation of the target elements between the adjacent images and also additional problems caused by deformed, deteriorated or missing sections can only be overruled by an aligning paradigm, which exploits all the pixel-level information, and results in an optimal fitting with selected precision. This paper presents a complex computer program called Optimal Alignment®, which performs the precise elaboration of X-Y shift and relative rotation of two consecutive images. The required searching process will be customized by setting four independent parameters which relate the span and density of the pixel-scanning basic process. Optimalization of fitting accuracy versus running time can be achieved by a rather short training period. The potential precision of Optimal Alignment based on complex algorythms is far superior to manual aligning of EM photographs with the eye-wrist-mouse facility. The resulted database of alignment orientation parameters can serve as an advanced source for the 3D reconstructing programs. Optimal Alignment® software tool (supported by Hungarian Space Office grant TP 138) will be demonstrated on a basal forebrain NPY+ axonal reconstruction, performed in L. Záborszky’s laboratory (supported by NIH grant NSO23945).]
