[Attachment as a predictor of risk for eating disorders on a representative hungarian adult sample]

SZALAI Dömötör Tamás, CZEGLÉDI Edit

[Background and purpose – Many studies confirm the relationship between attachment disturbances and (the severity of) eating disorders, however among them only one Hungarian study can be found. The exact predisposing traits of attachment and the strength of relationship is still uncleared. Our aim was to explore these aspects. Methods – Study was based on a cross-sectional nationally representative survey, called „Hungarostudy 2013” (N=2000, 46.9% males, mean age 46.9 years, SD=18.24 years). Measures: Sociodemographic and self-reported anthropometric data (weight and height), short Hungarian version of Relationship Scale Questionnaire, SCOFF questionnaire and short Hungarian version of Beck Depression Inventory. Results – The frequency of risk for eating disorders (anorexia or bulimia nervosa) was 3.9% (N=76) among the respondents (N=1860). Attachment anxiety was significantly higher in the risk for eating disorders group (t(1888)=-3.939, p<0.001), and significantly predicted the risk for eating disorders after adjusting for the potential background variables (OR=1.09, p=0.040). Detachment was not a significant predictor of risk for eating disorders (OR=0.98, p=0.515). Younger age (OR=0.97, p<0.001), higher level of depression (OR=1.09, p<0.001) and higher body mass index (OR=1.08, p<0.001) were also significant cross-sectional predictors of risk for eating disorders. The explained variance of the model was 10.7%. Conclusion – The study supported, that higher attachment anxiety is associated with the increased risk of eating disorders, with a possible therapeutic relevance. Assessment of attachment’s further aspects and creating multivariable models are required for more thorough understanding and optimising of intervention points.]

[Current questions of multiple sclerosis: the secunder progressive form of the disease]


[Recent data suggest that long-term worsening is common in relapsing-remitting multiple sclerosis patients and is largely independent of relapses or new lesion formation on brain MRI. The current definition of secunder progressive multiple sclerosis is worsening of disability independent of relapses over at least 6-month interval. Early focal inflammatory disease activity and spinal cord lesion are predictors of very-long term disease outcomes in relapse - onset multiple sclerosis. The potential of PET imaging to visualize hidden inflammation in MS brain in vivo is an important contribution for better understanding the progression of the disease. Therefore, PET imaging is a promising tool in detecting the conversion from relapsing remitting multiple sclerosis to secunder progressive form of multiple sclerosis. Furthermore, neuro-axonal damage is the pathological substrate of permanent disability in different neurological disorders including multiple sclerosis. The neurofilament proteins have promise in this context because their levels rise upon neuro-axonal damage not only in the cerebrospinal fluid but also in blood. Patients with increased serum levels of neurofilament at baseline, independent of other clinical and MRI variables, experience significantly more brain and spinal cord volume loss over 2 years and 5 years of follow-up. The kynurenine-pathway abnormalities may be associated with the swich from early-mild stage multiple sclerosis to debilitating progressive forms of the disease. Analysis of these metabolites in serum may have application as multiple sclerosis disease biomarkers. Free radical action has been suggested as a causal factor in the illness. Increased free radical production and consumption of the scavenger molecules were found during the active phase of the disease. Based on the clinical findings (EXPAND Study) and pathomechanism of the disease siponimod is approved by the US Food and Drug Administration for the treatment of relapsing remitting forms of multiple sclerosis, to include secunder progressive multiple sclerosis with active disease, relapsing-remitting multiple sclerosis and clinically isolated syndrome.]

[Practical use of meta-analyses in predicting disease risk, outcome, and therapy response in breast cancer]

KAHÁN Zsuzsanna, TARI Gergely, ENYEDI Márton, HARACSKA Lajos

[Germinal BRCA status infl uences patient care both in early and advanced/metastatic breast cancer. Ideally, the patient should make the decision on the type of surgery or the avoidance of radiotherapy being aware of the BRCA status; based on the most recent clinical studies, this knowledge may infl uence the type of chemotherapy in the neoadjuvant, adjuvant, or metastatic setting or may raise the use of emerging targeted therapies. DNA-targeting cytostatic agents, mostly platinum agents and PARP inhibitors that act by inducing synthetic lethality, provide specifi c therapies in BRCA-mutant cases. The optimum place and sequence of these specifi c agents in treatment, however, are not known yet. International guidelines promote BRCA testing for the specifi cation of treatment strategy in all HER2-negative advanced/metastatic breast cancer cases (NCCN) or at least in all cases when, based on certain predictors, the presence of mutations is likely (ESMO). Recently, the methods employed for BRCA testing have improved immensely and are widely available through the services of various providers. For the identifi cation of the mutation, sequencing of the whole genes is needed, which can be achieved faster and more cost-effi ciently using next-generation sequencing (NGS) platforms compared to previous methods. It is the responsibility of the physician to consider the possibility of BRCA mutations and to raise the issue of BRCA testing to the patient if the family history, the age, previous malignant disease(s) of the patient, or the cancer features are suggestive of genetic risk.]

[Experiences with the Hungarian version of the Sexual Risk Behavior Beliefs and Self-efficacy Scales ]


[INTRODUCTION - One of the most em­phasized areas of school health education is sexual safety. For risk reduction, adolescent’s beliefs and self-efficacy about sexual safety are decisive; however, no Hungarian measurement tool for this construction was available before. The aims of the present study were to adapt the Sexual Risk Behavior Beliefs and Self-efficacy Scales (SRBBS) to Hungarian, to explore the gender differences, and to assess predictors of condom use among high school students. METHOD - 9th and 10th class high school students in a north-Hungarian city were involved in our cross-sectional study (N = 649; 52.5% boys; mean age: 16.7 years; SD = 1.01 years). Measures: SRBBS questionnaire, sexual behavior issues. RESULTS - The psychometric analysis of SRBBS has yielded encouraging results. The theoretical factor structure is largely supported, the internal consistency of the scales is adequate and its test-retest reliability is mostly acceptable. 35.5% of the participants had sexual intercourse during their lifetime and 65.8% had used condoms at the last occasion. The boys (OR = 2.17, p = 0.021) and those who had more positive attitude towards condom use (OR = 1.24, p = 0.002) were significantly more likely to use a condom during the last act than girls, and subjects with less favorable attitude towards condom use. CONCLUSIONS - SRBBS questionnaire should be introduced into domestic research to measure the effectiveness of health check-ups and school health education programs. ]

[Hungarian Vasculitis Registry – results of the first five years]

HARIS Ágnes, TISLÉR András, ONDRIK Zoltán, FILE Ibolya, MÁTYUS János, ZSARGÓ Eszter, DEÁK György, AMBRUS Csaba

[Launching the Hungarian Vasculitis Registry aimed to collect information about prevalence and outcome of our patients with ANCA-associated vasculitis, and treatment protocols of the disease. The on-line data collection has been developing dynamically since its initiation five years ago, presently 278 patients’ files are available. Patients’ mean age is 58.2±14.5 years, 62% are women; their disease is associated with c-ANCA positivity in 51% and p-ANCA in 49%. At diagnosis GFR was 24.6±21.6 ml/min/1,73 m2, that time 29%, during the total follow up 39% of the registered subjects needed dialysis. Renal replacement therapy could be discontinued in 23% of them. In cases with focal histological changes, also with upper respiratory tract and skin involvement dialysis was significantly less frequently necessary, which underlines the importance of early diagnosis. In induction therapy steroid was administered for 94% of the patients, 85% of them got cyclophosphamide, 59% was treated by plasmapheresis, 11% got rituximab. Maintenance treat ment contained steroid in 80%, per os cyclophosphamide in 23%, parenteral cyclophosphamide in 22%, furthermore 40% of the patients got azathioprin, 8 subjects got mycophenolate and 6 got methotrexate. Median follow up was 30 months (IQR 6-78), during which period 20% of the patients died, 5% got kidney transplantation, and 5% were lost to follow up. Median survival was 14.8 years, five years survival was 85%, and ten years survival was 70%. Long term survival in patients with c-ANCA vasculitis seemed better comparing to p-ANCA vasculitis, but when correcting by age this difference disappeared. Predictors of death were age and dialysis dependent renal failure. Relapses developed in 27% of patients, 28% of them presented in the first year, 21% suffered it after five years of care. Collected data by the Hungarian Vasculitis Registry shows our society’s successful professional activity. Our results are comparable to the published data in the literature, yet there are several areas in our care where further improvements are warranted in order to increase our patient’s survival and quality of life.]

[Factors influencing anisocytosis among inpatients with chronic kidney disease]

MOLNÁR D. László, KISS István, SZAKONY Szilvia, AMBRUS Csaba

[The coefficient of variation of RDW (RDW-CV) is a predictor of mortality in several patient cohorts. RDW and other factors were analyzed in an earlier report as potential predictors of inpatient mortality. In this paper, determinants of RDW were examined in a sample of hospitalized patients with chronic kidney disease not yet on dialysis using both frequentist and bayesian ANCOVA models. For the non-informative Bayesian model no prior knowledge about the model parameters was assumed. For the informative Bayesian model prior knowledge from previous experience was applied. Calculations were performed in R with the faraway, car and MCMCPack programme packages. Male gender identity, higher mch and mcv were strongly associated with higher RDW. Blood glucose concentration, white blood cell count, blood hemoglobin concentration, platelet count, age and glomerular fil-tration rate showed inverse relationship with RDW levels. ]

Eating behaviors among the participants of an inpatient weight loss treatment


Background and purpose - Eating behaviors play a crucial role in the development and maintenance of excess weight. The aim of the study was to explore the predictors and changes in eating behaviors among overweight and obese patients. Methods - The sample of the 6-month prospective survey consisted of patients who participated in the inpatient weight loss treatment program in the Lipidological Department of the Szent Imre Hospital (baseline: N=339, 19% men; follow-up: N=175, 16% men). The mean age was 50.2 years (SD=13.47), the mean BMI was 38.6 (SD=7.58) at baseline. Measures: self-reported anthropometric data, Three-Factor Eating Questionnaire Revised 21-Items, CES-D Depression Scale. Results - According to the results of Multiple Indicators and Multiple Causes analysis, older age predicted greater cognitive restraint (b=0.12, p=0.047). Women were more prone to emotional eating than men (b=0.21, p<0.001). Higher levels of education predicted greater uncontrolled eating (b=0.16, p=0.007) and emotional eating (b=0.12, p=0.039). Depression showed a positive relationship with emotional eating (b=0.19, p=0.001), and mediated the relationship between gender and emotional eating (b=0.04, p=0.009), and BMI and emotional eating (b=0.03, p=0.015). Those whose weight loss was at least 5% showed a greater improvement in the eating behaviors than those whose weight loss was below 5% (cognitive restraint: t(168)=-4.765, p<0.001, uncontrolled eating: t(168)=-2.442, p=0.016, and emotional eating: Z=-2.011, p=0.044). Conclusions - Results reveal certain determinants of eating behaviors that enhance or obstruct successful long term weight loss and highlight the role of eating behavior changes in weight loss. These mark intervention points for the optimization of results achievable by weight loss treatments.

[Plasma ortho-tyrosine/para-tyrosine ratio predicts hyporesponsiveness to erythropoiesis-stimulating agents in dialyzed patients]

KUN Szilárd, MIKOLÁS Esztella, MOLNÁR Gergő Attila, SÉLLEY Eszter, LACZY Boglárka, CSIKY Botond, KOVÁCS Tibor, WITTMANN István

[Objectives: Patients suffering from end-stage renal failure (ESRF) are mostly treated with erythropoiesis-stimulating agents (ESAs). They often show hyporesponsiveness to ESA, which condition is associated with elevated production of free radicals. Phenylalnine (Phe) is converted into para- and ortho-tyrosine (p- and o- Tyr) by hydroxyl free radical. o-Tyr is produced exclusively in this way. However, physiological isomer p-Tyr is formed in significantly higher amounts by phenylalaninehydroxylase, mainly in the kidney. It has been shown that p-Tyr production is decreased in ESRF. As a result, p-Tyr can be replaced by o-Tyr in proteins, e.g. in proteins playing part in signal transduction of erythropoietin. We aimed to study the association of different Tyr isoforms with ESA-responsiveness. Methods: Four groups of volunteers were involved in our cross-sectional study: healthy volunteers (CONTR; n=16), patients on hemodialysis without ESA-treatment (non-ESA-HD; n=8), hemodialyzed patients with ESA-treatment (ESA-HD; n=40) and patients on continuous peritoneal dialysis (CAPD; n=21). Plasma p-, o-Tyr and Phe levels were detected using a high performance liquid chromatography (HPLC)-method, with fluorescence detection. ESA-demand was expressed as ESA-dose, ESAdose/ body weight and erythropoietin resistance index1 (ERI1, weekly ESA-dose/body weight/hemoglobin). Multivariate regression models were used to examine predictors of ESA-demand. In these models, most of the known predictors of ESA-hyporesponsiveness were included. Results: Lower p-Tyr levels were found in dialyzed patients compared with control subjects. In contrast, o-Tyr levels and o-Tyr/p-Tyr ratios were higher in dialyzed patients. Regarding dialyzed patients, o-Tyr level and o-Tyr/p-Tyr ratio were higher in ESA-HD than in non-ESA-HD and CAPD groups. Weekly ESA-dose/body weight and ERI1 correlated with o-Tyr/p-Tyr ratio (r=0.441, p=0.001; r=0.434, p=0.001, respectively). Finally, o-Tyr/p-Tyr ratio proved to be an independent predictor of ERI1 (β=0.330, p=0.016). Discussion: Our results suggest that elevation of o-Tyr/p-Tyr ratio could be responsible for ESA-hyporesponsiveness in dialyzed patients.]

[Electronic cigarette use among students in higher education]

PÉNZES Melinda, PONGOR Vince, KIMMEL Zsófia, BALÁZS Péter

[INTRODUCTION - Advantages and disadvantages of electronic cigarette (e-cigarettes) use with increasing popularity among young adults generated continuous debates both nationally and internationally. The aim of our study was to assess the prevalence of e-cigarette use in this population, and to explore sociodemographic, smoking-related and general health behavior predictors of its ever use. METHODS - Our cross-sectional study with anonymous, self-administered questionnaire was conducted among college/ university students (n=889) during a summer festival. Additionally to descriptive analyses, multivariate logistic regression model was applied (p<0.05) to identify factors predicting the initiation of e-cigarette use. RESULTS - One-third of our population has ever tried e-cigarettes, mostly daily smokers, but almost 15% of never smokers also tried it. In total, current use of e-cigarettes was only 1.2%. Odds ratios (ORs) of trying e-cigarettes were higher among daily smokers (OR=3.28) ever smokers (OR=2.10), males (OR=1.88) and those who did not care consciously for their health (OR= 1.65). CONCLUSIONS - Our sample in a recreational environment showed higher rates of ever use of e-cigarette however, current use proved to be lower if compared with previous international studies. Our results may provide basic information in this topic to further national and international surveys.]

[Drug use and death-seeking behaviour attitudes toward death among opiate users]

PAP Ágota, HEGEDÛS Katalin

[Many times, behind mens’ fears there is the fear of death. Drug use can be defined as a kid of self destruction, so it is directly linked to attitudes toward death. In Hungary, suicide among young people is one of the leading causes of death, which is often associated with some kind of addiction or substance abuse. We can also say that drug use is an indirect way of “death search”, which prolongs the agony and the time of suffering. Drug-related death can be directly attributed to drug overdose. Intravenous drug use may cause a risk of infectious diseases (such as sharing needles/syringe/filter use) - HCV, AIDS, etc. Intravenous drug use is mostly - but not exclusively - characteristic to opiate users. Heroin’s mode of action is described as causing an intense feeling of euphoria and a way of feeling augmenting to stupor. Its addictive potential is very high, the degradation is visible and can be fatal. In this paper, we discuss previous observations on overdose that is the validity of harm reduction justified by former research, the possible predictors of overdose and the identification of the prevention area.]
