[Atherosclerosis: an ancient process in a new interpretation]

REIBER István

[The progress of atherosclerosis starts in childhood and lasts until the body dies. Most cardiovascular diseases and deaths can be traced back to atherosclerotic vascular changes. The process is thousands of years old, but its complex pathophysiology becomes recognized and realised only nowadays. Based on the evidence available today, atherosclerosis is such a chronic inflammatory disease of large- and medium-sized arteries, which is characterized by lipoproteins and immune cells transformed through oxidative and other changes and subendothelial accumulation of extracellular matrix. Innate and adaptive immunity provide a complex regulating system of atherogenesis, which while directing specifically the pro-atherogenic inflammatory and atheroprotective anti-inflammatory processes intensify plaque progression or even stabilize them respectively. With our growing knowledge about the pathology of atherogenesis, we can further improve the identification of cardiovascular risk conditions and apply more personalized therapeutic strategies.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]

[Metals and cancer]

VETLÉNYI Enikő, RÁCZ Gergely

[We often tend to forget about our environment when looking for the origin of a disease. Inhaled air, drinking water and food, substances in contact with the skin all have an effect on the human body. Metals are indispensable parts of our everyday lives, their mining, processing and use cause a continuous exposure to them. Metal exert their effects on the body in various ways. Many of them are essential for maintaining homeostasis, but excessive or harmful metal intake can lead to health damage, including tumour formation through multiple attack points. Metals substitute each other during different transport processes and in the structure of proteins, they cause oxidative stress and bind to DNA, thereby damaging it. Applying them appropriately, the proapoptotic effect of the metal compounds is brought to the fore, thus becoming a therapeutic tool for tumours. Nowadays, platinum(II) compounds are widely used as chemotherapeutic agents and there are many ongoing studies to fi nd metal compounds with an ideal therapeutic and side-effect profi le. The aims of this article were to draw the attention to the dangers of metals in relation to cancer and to highlight their diverse application possibilities in current and future cancer therapy and diagnostics.]

DEÁK András, FUSZ Katalin, PRÉMUSZ Viktória, RAPOSA L. Bence, VÁRADYNÉ Horváth Ágnes, MADARÁSZ Ildikó, OLÁH András

[With the development of the equipments of extracorporeal circulation, international studies underline reducing the amount of filling fluid. Our retrospective study was conducted at the Heart Surgery Clinic of the University of Pécs between 1 January 2017 - 31 December 2017 with ECC cardiac operated patients. During the document analysis, data were collected from 157 patients between 50 and 70 years who underwent CAB surgery. They were classified into Low- (n=47) and Standard-prime (n=110) group. Medium negative correlation (r=-0.28; p<0.001) was found between prime/body surface area and haematocrit during last perfusion. As inflammatory parameter, the last measured CRP values were 36.00 mg/l (low) vs. 70.62 mg/l (standard). Our research justified the use of low-prime during ECC. The implementation of the method requires the scientific advancement of perfusionists, the preparation of national protocols and the improvement of the perfusionist’s training and legal background. ]

[Nutritional changes in the elderly]

NAGY-LŐRINCZ Zsuzsanna, ZÁMBÓ Leonóra, MARGARITOVITS Tijana, VARGA-NAGY Veronika, VARGA Anita, ZENTAI Andrea

[Since population ageing is one of the greatest problem of our time, we should aim not only to increase life expectancy but also healthy life years. Ageing is considered to be a normal biological process that can be characterized by the decline of body functions contributing to the age-related changes in nutrition as well. Although the process is not necessarily accompanied by pathological conditions (such as malnutrition, dehydration, obstipation, cognitive deterioration, fragility, polypharmacy), the evolving physiological changes undoubtedly increase the susceptibility to diseases and accidents. Elderly care should be adapted to the evolving changes, and should meet the person’s specific needs. ]

[The ACE2-Ang(1-7)-Mas axis as a new option for lowering blood pressure]

KÉKES Ede

[The ACE2-Ang(1-7)-Mas axis counterbalances the ACE/Ang II-AT1R axis in our body in order to maintain normal homeostasis. During the Covid-19 pandemic, this protective system came to the fore again and its beneficial effects on the cardiovascular-metabolic system, including the significant antihypertensive effect, are being clarified. In our brief summary, we analyze the essential aspects of this research.]

[Frequency and risk factors of “de novo” tumors after kidney transplantation ]

BORDA Bernadett, HÓDI Zoltán, SZEDERKÉNYI Edit, OTTLAKÁN Aurél, SEREGÉLY Edit, LÁZÁR György, KERESZTES Csilla, VIRÁG Katalin

[After kidney transplantation, the administration of immunosuppressive therapy not only renders the patient susceptible to infections, but it may also damage the function of tumor cell recognition and elimination. Our study was performed at the Department of Surgery, University of Szeged. After establishing the inclusion criteria, 570 patients were involved in the study. We examined the age, sex, immunosuppressive therapy of the patients, and searched for the rela­tionship between the different immunosuppressive agents and the type of the tumor. In 81 cases, de novo cancer was diagnosed. Among patients treated with cyclosporin and tacrolimus there was no significant difference in the mean age (p = 0.734) and body mass index (p = 0.543). There was no significant difference in graft function between the two groups of patients (Tac vs Cyc; 44 vs 20). Related to the time passed since the trans­plantation to diagnosing the tumors the earliest were prostate and cervix cancers however without significant difference. Skin cancers are the most frequent followed by post-transplant lym­pho­prolife­ra­tive diseases. The increasing risk of developing tumors is mainly due to immunosuppressive therapy. ]

[Systolic and diastolic blood pressure by height, BMI, gender and age between 14 and 18 years of age]

SZABÓ László, SCHEURING Noémi, GÁCSI Erika, KORMOS-TASI Judit

[The aim of the screening program was to investigate blood pressure levels in different ages according to obesity. Blood pressure, heart rate, body composition, bodyweight, height and BMI were assessed. 2202 adolescent (1326 girls, 876 boys) participated in the screening program. The mean systolic blood pressure of all screened adolescents was 126.34 ± 12.55 mmHg. Boy/girl values were 131.87 ± 13.59/117.49 ± 5.69 mmHg, p < 0.001. The mean diastolic blood pressure of all screened adolescents was 71.86 ± 8.74 mmHg. Boy/girl values were 72.61 ± 9.17/66.69 ± 5.04 mmHg, p < 0.001. The 50%, 90%, 95%, and 99% thresholds and cases for systolic, diastolic blood pressure, and the BMI and BodyFluid thresholds, detailed for 14–18 year olds, girls and boys, are tabulated. Systolic blood pressure (SBP) was over 99% in 12 girls (14- year-olds), 39 (15), 42 (16), 33 (17), 5 (18) to height. SBP was over 99% in 17 boys (14-year-olds), 73 (15), 100 (16), 33 (17), 5 (18) to height. It is emphasized that systolic blood pressure (SBP) is > 99% in 12 girls (14 years), 39 (15), 42 (16), 33 (17), 5 (18) to body height. SBP > 99% for 17 boys (14 years), 73 (15), 100 (16), 33 (17), 5 (18) to body height. Elevated diastolic values were associated with elevated systolic values, but less occurred. The percentage of high blood pressure was more frequent among boys and girls who were in the overweight group (58.6% and 18.6%). Normal blood pressure is higher in overweight and obese adolescents and is a significant risk factor for developing high blood pressure in young adulthood.]

[The complex intensive care and rehabilitation of a quadriplegic patient using a diaphragm pacemaker]

FODOR Gábor, GARTNER Béla, KECSKÉS Gabriella

[A 21 year female polytraumatized patient was admitted to our unit after a serious motorbike accident. We carried out CT imaging, which confirmed the fracture of the C-II vertebra and compression of spinal cord. Futhermore, the diagnostic investigations detected the compound and comminuted fracture of the left humerus and femur; the sacrum and the pubic bones were broken as well. After the stabilization of the cervical vertebra, a tracheotomy and the fixation of her limbs were performed. She spent 1.5 years in our unit. Meanwhile we tried to fix all the medical problems related to tetraplegia and respiratory insufficiency. As part of this process she underwent an electrophysiological examination in Uppsala (Sweden) and a diaphragm pacemaker was implanted. Our main goal was to reach the fully available quality of life. It is worth making this case familiar in a wider range of public as it could be an excellent example for the close collaboration of medical and non-medical fields.]

[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.]
