The effects of 30 Hz, 50 Hz AND 100 Hz continuous theta burst stimulation via transcranial magnetic stimulation on the electrophysiological parameters in healthy individuals

OZDEMIR Zeynep, ACAR Erkan, SOYSAL Aysun

Transcranial magnetic stimulation is a non-invasive procedure that uses robust magnetic fields to create an electrical current in the cerebral cortex. Dual stimulation consists of administering subthre­shold conditioning stimulation (CS), then suprathreshold test stimulation (TS). When the interstimulus interval (ISI) is 1-6 msec, the motor evoked potential (MEP) decreases in amplitude; this decrease is termed “short interval intracortical inhibition” (SICI); when the ISI is 7-30 msec, an increase in MEP amplitude occurs, termed “short interval intracortical facilitation” (SICF). Continuous theta burst stimulation (cTBS), often applied at a frequency of 50 Hz, has been shown to decrease cortical excitability. The primary objective is to determine which duration of cTBS achieves better inhibition or excitation. The secondary objective is to compare 50 Hz cTBS to 30 Hz and 100 Hz cTBS. The resting motor threshold (rMT), MEP, SICI, and SICF were studied in 30 healthy volunteers. CS and TS were administered at 80%-120% and 70%-140% of rMT at 2 and 3-millisecond (msec) intervals for SICI, and 10- and 12-msec intervals for SICF. Ten individuals in each group received 30, 50, or 100 Hz, followed by administration of rMT, MT-MEP, SICI, SICF immediately and at 30 minutes. Greater inhibition was achieved with 3 msec than 2 msec in SICI, whereas better facilitation occurred at 12 msec than 10 msec in SICF. At 30 Hz, cTBS augmented inhibition and suppressed facilitation, while 50 Hz yielded less inhibition and greater inter-individual variability. At 100 Hz, cTBS provided slight facilitation in MEP amplitudes with less interindividual variability. SICI and SICF did not differ significantly between 50 Hz and 100 Hz cTBS. Our results suggest that performing SICI and SICF for 3 and 12 msec, respectively, and CS and TS at 80%-120% of rMT, demonstrate safer inhibition and facilitation. Recently, TBS has been used in the treatment of various neurological diseases, and we recommend preferentially 30 Hz over 50 Hz cTBS for better inhibition with greater safety and less inter-individual variability.

[BLS Quality Assessment – The Effectiveness of Telephone Cardiopulmonary Resuscitation Inst­ruction]

KÖCSE Tamás, MÁTÉ Martin, HORVÁTH Balázs, PAKAI Annamária, MÁTÉ-PÓHR Kitti

[The aim of the presented study is to monitor the effectiveness of BLS, to investigate its effectiveness in laymen’s groups, and to compare whether non-instructional or T-CPR is more effective. Our quantitative, cross -section study was conducted on the open day of 112 Call Center in Szombathely. The target group consisted of visiting lay people who signed a statement of consent to process their observation results (n = 19). Descriptive statistics were calculated using IBM SPSS for Windows 22.0 and Fisher-exact test and independent samples T-test (p <0.05). In the case of chest compressions, all parameters examined were more effective during manual resuscitation with telephone instruction. Without instructions, it takes an average of 12 sec. from the rescue call to start the compression, in the situation where instruction takes an average of 1 m. 25 sec. Our results suggest that T-CPR takes longer to complete chest compressions than non-instructed cases, but overall, chest compressions are more effective. ]

MOSKOLA Vladimír, SUSÁNSZKY Éva, SZÉKELY Andrea, HORNYÁK István, OZSVÁRT Barbara, NÉNINGER Tibor, BALOGH Zoltán

[The development of the family, family relations and family socialization play a decisive role in becoming an adult and in the development of later forms of behavior. Parental treatment is closely related to problem-solving skills, which is why they can influence adequate responses to unexpected situations in ambulance care. The aim of the study: to explore and analyze the parental attitudes and behaviors that emerged during the upbringing of outgoing ambulance workers and can be related to the demographic, socio-economic characteristics of the study sample, as well as work, workplace and health behaviors. The survey was conducted between the employees of the National Ambulance Service and the participants of the National Ambulance Professional Section of the HHCP. In addition to demographic, workplace, and health status questions, the authors surveyed a shortened, 23-question version of the Egna Minnen Beträffande Uppfostran (s-EMBU) questionnaire developed by Perris et al. SPSS version 25.0 was used for statistical analyses. Types of analyses included descriptive statistics, two-sample t-test, correlation calculation, analysis of variance. The authors found striking correlations between religion, especially school graduation and female gender, as well as restrictive and gay parental treatment. The maternal rejection and paternal overprotection have been shown to be prominent among people those working in the capital, with the correlation that the “diversity” provided by the big city is particularly conducive to breakaway behavior and good social relationships. The parental restriction, as one of the characteristic parental behaviors revealed in our research, and its positive relationship with religiosity and higher school graduation in the part of Emergency Medical officers who work in higher positions raises the possibility that the professional appearance of helping and life-saving activities is influenced by religiosity and the resulting development of moral and social sensitivity during upbringing. ]

[Examination of the Strength of Core- and Perineal Muscles in Case of Different Movements]

KISS Noémi, BAJSZ Viktória, PAKAI Annamária, CSÁSZÁR Gabriella Edit

[Aims of the study: to measure the strength of core-, perineal muscles in three groups, to compare different exercises for the aspect of these muscles. 11 sedentary-, 10 women’s doing Pilates, 13 inactive female sudent’s core- and perineal muscles were measured in longitudinal study by DAVID-machine, modified Plank-test, FemiScan at Univerity of Pécs, Faculty of Health Sciences, Zalaegerszeg, 2016. february-november. Data analysis: ANOVA, Scheffe Post Hoc test, two-tailed T-test. The TS-group’s muscles became more symmetrical (p=0.043). According to Plank test, the TS-group’s 3th result became stronger than FH-group (p=0.001) and the PT-group (p=0.018) at first. About the perineal-muscles: usually the PT-group achieved the best results. The FH-group’s perineal-muscles in case of relaxation were significantly symmetrical (p=0.038) than the TS-group’s after training. Pilates-method turned out to be effective to improve the strength and stamina of core muscles. Core-training is effective to improve core muscles, but not enough for perineal muscles with the given frequency and intensity. ]

[Complication of the Metabolic Syndrome in Women with Polycystic Ovary Syndrome]

KOMLÓSI Kálmánné, KISS Sarolta, FERENCZY Mónika, MÁTÉ-PÓHR Kitti, PAKAI Annamária

[In our research we compared whether pregnant women with polycystic ovary syndrome or the mothers who were healthy through pregnancy has a higher risk to develop high BMI, metabolic syndrome, preeclampsia, polyhydramnion and macrosomia. Our research is a retrospective, cross-sectional study. In the random sampling within the target group, the target group was diagnosed with PCOS (n=50) and the control group was mothers who had undergone uninterrupted pregnancy (n=50). The exclusion criterion is the coexistence of other endocrine disease that may affect the parameters under consideration, in addition to the control group the diagnosis of PCOS. With IBM SPSS for Windows 22.0, we applied two-sample T-test and Khi2 test (p<0.05). The BMI values ​​measured in the PCOS study group are higher than in the control group (p<0,05). Pregnant women with PCOS has a higher risk of developing high blood pressure, and high cholesterol (p<0,05). The difference between the two groups can not be considered significant for the development of proteinuria and oedema. Emphasis should be placed on PCOS gravid care, early detection of metabolic disturbances, accurate documentation, and elimination of complications and illnesses associated with the disease.]

[Hypertension aspects of Hungary’s Comprehensive Health Screening Program (MÁESZ) – The first 10 years]

BARNA István, KÉKES Ede, DAIKI Tennó, DANKOVICS Gergely

[Screening tests are known in GP practice, but it is also important for the population living away from the test sites to have access to screenings and to know the information that can be obtained. Hungary’s Comprehensive Health Screening Program 2010-2020 is a unique initiative in Hungary and in the world. It is the largest health protection program in Hungary, operating in a humanitarian form, which provides the population with free-of-charge screening with the most modern tools, keeping in mind the importance of prevention. The program is performed by the cooperation of 76 professional organizations, the national program for the prevention and treatment of cardiovascular diseases coordinated by the Association of Hungarian Medical Companies and Associations (MOTESZ) on the basis of European Union directives, and by consensual cooperation. In this publication, we present some hypertension-related data performed among 2010-2019.]

[New results of neuroscience research – the background of symptomatological and etiological diversity of mental disorders]

OSVÁTH Péter

[Nowadays, the focus of genetic, neurobiological, neuropsychological and psychosocial research is on a more accurate discovery of the etiology of mental illnesses, especially with regard to the role and complex interactions of certain risk factors. It is increasingly challenging to interpret the results of different aspects and methodologies in a coherent theoretical framework, as this can only lead to a more accurate understanding of the complexity and mechanism of the psychiatric disorders. The main aim of this paper to overview recent studies on etiological background of mental disorders and to present the most important aspects of the Research Domain Criteria (RDoC) system. Review of reports from comprehensive studies published in the most important psychiatric journals over the past five years summarizing new findings on the etio­logy of mental disorders. Although current classifications indicate that mental disorders are strictly distinct diagnostic categories, new findings suggest that these marked differences in symptomatic, genetic, and neurobiological backgrounds are not detectable, as many mental disorders have been identified as having common molecular genetic risk factors, which may indicate common neurobiological pathomechanisms. Research results support the need for a rethinking of psychiatric nosology on an etiological basis and represent an important step forward in the more accurate exploration of the neurobiological background factors of mental disorders and thus in the development of more targeted therapeutic approaches. The development of the RDoC system can be a great help in this, as this dimensional approach offers the possibility of integrating the - often diffuse or even contradictory - neuroscientific research findings into a unified theoretical framework for the etiology, nosology and treatment of mental disorders. ]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]
