RESUMO
Stroke is nowadays one of the most prevalent diseases worldwide causing devastating impairments and negative consequences for survivors. It is a main cause of adult onset disability and it can have a negative impact on psychological health, cognitive function and quality of life. Post-stroke rehabilitation may reduce long-term disability, and in recent years several innovations have emerged to improve recovery. Decades of research suggest that mindfulness-based interventions support a greater capacity to live with chronic medical conditions and contribute to lowering stress levels. Previous works report positive results amoung stroke survivors, improvements in mood, mental fatigue and in some degree in cognitive and physical functioning, plus represent a promising option in secondary prevention. Since the early 2000s, numerous clinical studies have investigated the efficacy of mindfulness-based interventions in post-stroke rehabilitation. In this paper the main results of the relevant international research is reviewed and also, the main modalities of the mindfulness-based interventions are presented. Our primary goal is to evaluate the results in order to draw attention to the importance of rehabilitation of patients with stroke and hopefully the theoretical and practical knowledge of the review will contribute to development effective and secure protocols in future research. Mindfulness-based techniques can become clinically valuable complementary therapeutic interventions in post-stroke rehabilitation. More research in this area is warranted: to evaluate these specific practices and their suitability; using randomized, controlled, follow up designs, rigorous methods, and different treatment settings; expanding outcomes to include physiological, health care use, and health-related outcomes; exploring mediating factors; and discerning dose effects and optimal frequency and length of practice.

PURPOSE: The multidimensional role of hamstring muscle group strength in athletic performance and injury prevention is well documented, and nordic hamstring exercise (NHE) is a popular method for the development of hamstring strength. Our aim was to examine the EMG characteristics of the eccentric NHE as well as the effects of long-term eccentric NHE training on muscle strength and vertical jump performance in 10- to 11-year-old female handball players. METHODS: Players from the same handball team were randomly assigned to an eccentric NHE training (13 players) or a control group (10 players). Both groups continued their regular handball training routine, but the NHE group performed additional eccentric NHE exercises once or twice a week, with progressively increasing volume, over 20 weeks. To test training effects, countermovement jump (CMJ) height, eccentric hamstring impulse, peak torque, and angle of peak torque were evaluated before, during and after the training period. In the pre-exercise test, EMG activity of the medial and lateral hamstring muscle was also assessed during NHE. RESULTS: Hamstring activities ranged between 98 and 129%. Lateral hamstring activity was greater than medial only in the right leg during NHE. Eccentric hamstring impulse improved in both legs at 10 weeks in both groups. Then, at 20 weeks, it remained unchanged in the NHE but decreased in controls. A similar adaptation was seen in eccentric hamstring torque, without change in the optimum knee angle. CMJ height improved only in the NHE. CONCLUSION: It is concluded that NHE activates the hamstring musculature effectively, and a favourable mechanical adaptation to long-term NHE exercise in girls can be triggered as early as 11 years of age.

AIMS: Prosthetic graft infection frequently requires graft replacement. Among other options, a biological graft could serve as an alternative choice. Decellularization reduces tissue immunogenicity. Our aim was to determine an efficient decellularization method and to evaluate the decellularized porcine biografts' adaptability. METHODS: Four different protocols were implemented to decellularize porcine aortic segments (n = 4). Cell removal effectiveness and matrix structure preservation were histologically examined. Mechanical tests were performed. Decellularized porcine grafts were interpositioned in a porcine aorta. After a 6-month period, implanted samples were removed and evaluated using light and electron microscopy. RESULTS: Histological results showed complete removal of cells and preserved connective tissue fiber structure following decellularization, using sodium dodecyl sulfate and sodium azide. Pressure tests demonstrated similar compliance to fresh vessels. In 9 out of 10 cases, pigs survived the follow-up period. Graft rejection, intimal hyperplasia, reocclusion and/or aneurysm formation were not observed. Presence of host cells and neoendothelialization were microscopically confirmed. CONCLUSIONS: This decellularization protocol enables a cost-effective preparation of biological grafts featuring reduced immunogenicity. The implanted grafts did not degenerate during the 6-month follow-up period, the lack of graft rejection suggests acceptable immunological tolerance, while recipient cells migrate into, proliferate and differentiate, thus creating the possibility for further use as an optional vascular graft.

Thoracic aortic endograft implantation has become a widespread procedure in recent years, yet no report is available about Hungarian outcomes. Examination of our results is crucial to define further treatment strategies. Analysis of perioperative data from Hungarian thoracic endograft implantations based on the experience of 5 years is presented. Our retrospective, multicentric study analysed voluntarily reported data from all Hungarian institutions where thoracic endograft implantations are performed. Information was collected from every procedure performed in 5 years. Between 2012 and 2016, 131 thoracic stent graft implantations were performed in Hungary (67.18% male, mean age 62.80 years). 25.19% of the procedures were acute. 13.74% of the patients were diabetic. Indications for the procedure were aneurysm (64.89%), dissection (17.56%), aortic trauma (6.87%) and other conditions (10.69%). 73.91% of the dissection cases were acute. 16.47% of repaired aneurysms were ruptured. Additional preoperative revascularization (debranching) was performed in 26.72% of the cases. Postoperative stroke occured in 4.58%, temporary hemodialysis was needed in 1.53%, bowel ischaemia was present in 2.29% and reoperation within 30 days was needed in 5.34% of all cases. Thirty-day mortality of the procedure was 9.92%, 5-year long-term mortality reached 16.03%. Endovascular repair of the thoracic aorta is an effective procedure and our national data comfirmed its advantages compared to open thoracic surgery. Further use of the procedure in Hungary depends on the centralised care in vascular surgery and financial matters. Multidisciplinary cooperation and proper logistics are needed to provide patients with optimal treatment. Orv Hetil. 2018; 159(2): 53-57.

[Purpose] Investigation of the efficacy of robot-mediated therapy of the upper limb in patients with chronic stroke, in task-oriented training activities of daily living in real environment. [Subjects and Methods] 20 patients, each more than one year post-stroke (13-71 months) received 20 sessions of upper limb robot-mediated therapy. No other treatment was given. Each therapy session consisted of a passive motion and an active task therapy. During the active therapy, subjects exercised 5 activities of daily living. Assessments of the subjects were blind, and conducted one month prior to, at the start, at the end, and three months after the therapy course. The following outcome measures were recorded: Fugl-Meyer Scale-upper extremity subsection, Modified Ashworth Scale, Action Research Arm Test, Functional Independence Measure, Barthel Index. [Results] Significant improvements were observed between the start and the end of the therapy, except for Modified Ashworth Scale and Barthel Index. Results still held up at the follow-up visit three months later. [Conclusion] Practicing activities of daily living in real environment with robot-mediated physical therapy can improve the motor and functional ability of patients, even with relatively good initial functions, and even years post-stroke.
RESUMO
Acute kidney injury (AKI) remains an independent risk factor for mortality and morbidity after vascular surgery (affecting the renal arteries) or aortic surgery (requiring suprarenal aortic clamping). These types of vascular surgery produce renal ischemia/reperfusion (I/R) injury, a common cause of AKI. The present studies aimed at monitoring the course of renal I/R injury at the cellular level and investigating the efficacy of long-term preoperative and single-shot intraoperative administration of sodium pentosan polysulfate (PPS) to protect renal tissue from acute I/R injury both in native and diabetic kidneys in rats. Western blot analyses of the proapoptotic (bax) and antiapoptotic (bcl-2) signaling pathways, as well as the extent of DNA damage (phospho-p53), were performed. Oxidative stress followed upon the termination of malondialdehyde, reduced glutathione, thiol group, and superoxide dismutase plasma levels. Inflammatory changes were measured by the determination of serum tumor necrosis factor-α and interleukin-1 levels. Morphological changes were detected by histological examinations. Our results showed that the long-term administration of PPS has an advantage in reducing I/R kidney injury in diabetic rats, while high-dose, single-shot parenteral administration of PPS prior to revascularization might be useful in nondiabetic rats.

Decreasing the often-seen multiple disabilities as a consequence of central nervous system impairments requires broadening of the tools of rehabilitation. A promising opportunity for this purpose is the application of physiotherapy robots. The development of such devices goes back a quarter of century. Nowadays several robots are commercially available both for supporting upper and lower limb therapy. The aim is never to replace the therapists, but rather to support and supplement their work. It is worthwhile applying these devices for goal-oriented exercises in high repetition, which one physically fatiguing for the therapist or for the correction of functional movement by various strategies. Robot mediated therapy is also useful for motivation of the patient and making the rehabilitation programme more versatile. Robots can be used for assessment of the neuromotor status as well. Several clinical studies have been executed in this field, all over the world. Meta-analyses based on randomized, controlled trials show that supplementing the traditional physiotherapy with a robot-mediated component presents advantage for the patients. Further studies are necessary to clarify which modality and intensity of the exercises, in which group of patients, in which stage lead to the expected outcome.

AIMS: We studied the effects of the inhibition of the endogene antioxidant glutathione-S-transferase (GST) by ethacrynic acid (EA) on ischemia-reperfusion (IR) injury and postconditioning (PC) in the lower extremities. We aimed to examine the oxidative stress parameters (OSP), inflammatory response and activation of proapoptotic signaling proteins (PSP) after revascularization surgery. METHODS: Sixty Wistar rats were divided into 6 groups: control, IR, PC, EA-control, IR and administration of EA (IR/EA) and PC and administration of EA (PC/EA). The IR, PC, IR/EA and PC/EA groups underwent 60 min of infrarenal aortic cross-clamping. After that, PC was performed in the PC and PC/EA groups. In 3 of the groups, the animals were treated with EA (EA-control, IR/EA and PC/EA groups) as well. The ischemia was followed by 120 min of reperfusion. Blood samples and biopsy specimens were collected from the quadriceps muscle. Plasma malondialdehyde, reduced glutathione, thiol/sulfhydryl group levels, TNF-α and IL-6 concentrations and superoxide-dismutase enzyme activity were measured. RESULTS: The levels of the OSP and the inflammatory proteins were higher in the EA-administered groups. The ratio of phosphorylated PSP was higher in the EA-administered groups and the protective effect of PC did not develop. CONCLUSIONS: Inhibition of GST by EA augmented the IR damage. GST inhibition was associated with a different activation of the mitogen-activated protein kinases and the PSP, regulating these pathways in the process of apoptosis and PC.

INTRODUCTION: Cerebral hyperperfusion syndrome is a rare, hardly known condition, which can result in serious complications either after surgical or endovascular revascularization. Recognition of the typical triad (headache, seizure, focal neurological deficit) and the prompt radiological diagnosis (sonography, computed tomography) are crucial to achieve a favourable outcome. AIM: The aim of the authors was to select the endangered group and set up an effective therapeutic protocol based their own experience in combination with relevant literature data. METHOD: From the beginning of 2010 up to now three cases with these symptoms pursuant to the criteria of cerebral hyperperfusion syndrome have been recognized by the authors. RESULTS: Each of the three patients were treated by similar principles on intensive care unit, but the applied therapy resulted in complete remission in one patient only. CONCLUSIONS: At present there is no efficient diagnostic way to screen the endangered group, hence the only opportunity for prevention is the appropriate perioperative blood pressure control. If symptoms have developed already, urgent treatment is required.

INTRODUCTION: In the pelvic region thrombendarterectomy and bypass procedures are the most commonly performed procedures to treat peripheral artery occlusive diseases with chronic, severe circulation failure caused by atherosclerosis. Biologic and synthetic grafts can also be used in bypass surgeries. Application of synthetic grafts can acutely increase the development of the infectious graft complication and its mortality is still between 70 and 75% in pelvic processes. We describe the difficulties and dilemmas of an infectious aortobifemoral graft. CASE PRESENTATION: 58-year-old female patient with right lower limb trophic ulcer underwent a DSA examination showing a bilateral iliac occlusion and aortobifemoral bypass surgery with Dacron graft implantation was performed. Re-occlusion and infection of the graft led to an in situ silver Dacron graft replacement. Due to the one-sided re-occlusion, a femoro-femoral crossover bypass surgery applying silver graft was performed. Despite the previously described procedures the infectious process got worse and autologous deep vein reconstruction was required beside the removal of the infectious synthetic grafts at the same time. DISCUSSION: There are local and extraanatomical solutions to reduce infectious graft complication. In pelvic infections bypass surgeries using autologous deep vein can show the best results. This procedure is the trustworthiest but also the most straining technique due to the extension of surgical time and increased blood loss. The proper surgical strategy should be selected on individual bases including cardiopulmonary load ability, patient age and technical/infrastructural possibilities.
RESUMO
Stroke can have a range of physical, psychological, cognitive, and social impacts that are challenging for survivors. This study aimed to evaluate the efficacy of a group-based mindfulness intervention integrated into an inpatient rehabilitation program compared to standard care. A single-center, randomized, controlled trial was conducted in 93 poststroke patients. The intervention group received 6-weeks of mindfulness-based cognitive therapy (MBCT) and standard care; the control group received standard care. Primary outcomes were depression and trait anxiety; secondary outcomes were trait mindfulness and attention. Participants completed questionnaires at baseline, and postintervention (6â weeks). Mixed-effect model repeated measures analysis of variance was conducted between groups and across time. A total of 80 participants (intervention n â =â 43; standard care n â =â 37) were included in the postintervention analysis. There were no statistically significant differences in the primary outcomes between the groups over time. An improvement was found, however, on the trait mindfulness observing subscale in favor of the intervention group. Eight sessions of MBCT integrated into an inpatient stroke rehabilitation program over 6â weeks was not effective in improving depression and anxiety compared to standard care. Lack of follow-up and low to moderate pathological symptoms at baseline may have limited the effectiveness of this intervention.

We have read several publications of great authority on the neurological profession in the last two years in which were expressed assessments of the current situation combined with opinions about neurology and the necessity to reorganize neurological patient care. These articles took up the question of neurorehabilitation too. The authors, who on a daily basis, deal with the rehabilitation of people with disabilities as a consequence of neurological conditions, summarize some important definitions of rehabilitation medicine and the present system of neurological rehabilitation, as it is defined by the rehabilitation profession.

Although malnutrition may negatively impact the outcomes of rehabilitation and increase the cost of care, there are still no valid nutritional assessment methods appropriate for specific groups of patients undergoing rehabilitation. This study aimed to determine if a multifrequency bioelectrical impedance is suitable for monitoring the changes in body composition of brain-injured patients for whom individualized nutritional goals were set during rehabilitation. Fat mass index (FMI) and skeletal muscle mass index (SMMI) were examined by Seca mBCA515 or portable Seca mBCA525 device within 48â h of admission and before discharge in 11 traumatic brain injury (TBI) and 11 stroke patients with admission Nutritional Risk Screening 2002 scores ≥2. The changes in outcomes and plausible interactions were examined between the admission values and the values estimated for the 18th day (minimum length of stay in the sample) using a repeated measure mixed-sample analysis of covariance. In patients with low FMI at admission (mainly younger, TBI patients, with longer ICU stay), there was no change over time whereas, in those with high admission FMI (older, stroke patients, with shorter ICU stay), a decrease was observed (significant interaction F(1,19)â =â 9.224 P â =â 0.007 Part. η² = 0.327). The SMMI significantly increased over time (F(1,19)â =â 5.202 P â =â 0.034 Part. η² = 0.215) independently of gender, age, days spent in ICU and cause of brain injury. Our results suggest that bioelectrical impedance analysis is feasible and informative for monitoring the changes in body composition during rehabilitation, which also requires consideration of demographic and pre-rehabilitation characteristics.

An aging society is a growing challenge for families, social and rehabilitation service providers, and economies. Information and communication technology-based assistive technology can bolster the independence of older adults (65 years and above) and reduce their burden on caregivers. Currently, there is no unified methodology to assess the effectiveness and acceptance of these technologies. The present study undertakes a scoping review to (1) identify and characterize the methods for assessing the acceptability and usability of information and communication technology-based assistive technologies, (2) explore the advantages and disadvantages of the assessment methods, (3) determine the possibilities of combining the assessment methods and (4) define the most commonly used assessment method and set of outcome measures. The literature was searched in MEDLINE, Scopus, IEEE Cochrane and Web of Science bibliographic databases using the keywords defined by reviewers for articles in English published between 2011 and 2021. Of the 1696 matches, 31 met the inclusion criteria. It was found that a combination of different assessment methods was common in outcome measurements. Of the 31 studies, assessment methods were combined in 21 studies and multiple questionnaires were used in 11 studies. The most common technique of outcome measurement was the use of questionnaires (81%), conducting interviews (48%) and recording usability-performance measures (39%). The advantages and disadvantages of the assessment methods could not be determined in the selected studies in this scoping review.

INTRODUCTION: Popliteal vein aneurysm is a rare, but potentially life-threatening condition that can lead to deep vein thrombosis and/or pulmonary embolism. It is often asymptomatic, but symptoms may include pain, post-thrombotic syndrome or chronic venous insufficiency. An experienced physician may be able to detect a palpable mass in the popliteal fossa. Duplex ultrasound is the first line of diagnosis. CT or MR venography play a role in the diagnosis. OBJECTIVE: To review the international literature, explain the possible treatment options, and present our case. CASE REPORT: A 62-year-old female patient had a recurrent pulmonary embolism while on direct-acting oral anticoagulant therapy. Duplex ultrasound and MR angiography were performed and confirmed a partially thrombosed aneurysm of the right popliteal vein. Aneurysm resection and venorrhaphy were performed as treatment. At follow-up, ultrasound showed adequate flow in the deep venous system. 6 months later, the control MR angiography showed good flow without stenosis. There were no postoperative complications. Discussion and literature review: The pathomechanism of the disease remains unclear. Treatment options are conservative therapy and/or surgical intervention, but there is no consensus regarding the therapy of symptomatic or asymptomatic cases. There is no clear statement regarding the method and duration of postoperative anticoagulant therapy. CONCLUSION: In the case of recurrent pulmonary embolism, the possibility of a popliteal vein aneurysm should be considered. Ultrasound is a non-invasive, widely available initial diagnostic tool. In addition to conservative treatment, the possibility of surgical intervention can be considered. The surgical procedure described in our case was successful. Orv Hetil. 2023; 164(39): 1544-1549.

The study aimed to reveal physical exercise conditions and catecholamine response-dependent differences while an individual experiences a flow state (FS) following noncompetitive and competitive running drills. Urine laboratory catecholamine levels were measured using a standard clinical method during pre- and post-physical exercises. The noncompetitive task involved intermittent running drills, from an absolute beginning up through exhaustion. Initially, the drill is performed individually then later competing alongside other runners. Twenty-two males (mean age: 40.27; SD: 5.4; min-max: 31-49 years) were selected in accordance to the following criterion: healthy status without using medication, routine forms of training (running, cycling or swimming) ideally performed with regularity, at least three times per week, 45 min per session. During the noncompetitive task, a high FS experience was associated with a low level of catecholamines, (noradrenaline and adrenaline) while in parallel, the high FS was associated with a low concentration of homovallinic acid. During competitive conditions, the FS-related catecholamine level changes have not yet been found. In conclusion, the low concentration of the circulating catecholamines supports the transient hypofrontality hypothesis regarding the FS experiences. Furthermore, synchronized noradrenaline and adrenaline neurosecretion play an essential role in the manifestation and the prolongation of FS in noncompetitive exercise conditions.

UNLABELLED: There are few data on the rehabilitation knowledge of medical specialists and medical students. AIM: Assessment of the rehabilitation knowledge of medical specialists working in general hospitals and of final year medical students. METHODS: A paper form survey was performed using a questionnaire containing seven multiple choice questions and three definitions. Questionnaires were filled in independently on the spot. The three answering groups were physicians (specialized in orthopedic surgery, neurology or neurosurgery) working in a general hospital that had a rehabilitation ward, final year medical students from Semmelweis University, and trainees in rehabilitation medicine. The survey was voluntary and anonymous. RESULTS: Forty physicians, 42 students and 39 rehabilitation trainees filled in the questionnaire. Half of the students gave correct answers to questions about rehabilitation specialization, the existing university chairs, the percentage of people with disabilities in Hungary, and the way of sending patients for rehabilitation consultation. The number of beds designed for rehabilitation was unknown, but with regard to the existence of regulation by law the rights of people with disabilities were well-known by all groups. Very few were able to define the basic categories (rehabilitation, disability). Rehabilitation knowledge of physicians was not better than that of students, but rehabilitation trainees were better informed. CONCLUSIONS: According to findings of the authors, students and physicians do not have enough rehabilitation knowledge to perform medical activities adequately. Enlargement of the medical curriculum with basic rehabilitation knowledge is essential. A rehabilitation training course is necessary for physicians to be better equipped to carry out their daily hospital work.

CASE REPORT: In this article we present a relatively rare vascular surgical complication and an uncommon treatment of it. In this case we used an aorto-bifemoral bypass on a patient with Leriche syndrome. The implanted Y-graft got infected and we were forced to remove it. Having inserted the abdominal aortic graft, an axillobifemoral bypass was also applied to secure the circulation of the lower limbs. However, the graft occluded later on, and 37 months after the inital surgery a rather large pseudoaneurysm developed at the origin of the graft in the right subclavian artery. Another surgical intervention was indicated to prevent embolisation, rupture and compression. Instead of the conventional surgical method (resection, interposition) we did an endovascular procedure. We removed the false aneurysm by inserting a covered stent, using catheter technique, into the right brachial artery and therefore prevented the previously mentioned complications. DISCUSSION: This minimal invasive method is very useful for high risk patients to prevent the injury of neighbouring anatomical structures in the region as well as minimize blood loss and potential complications of long term anaesthesia when open surgery is done.

The aim of this study was to reveal whether increased reward dependence (RD) plays a role in the catecholamine neurotransmitter release and testosterone hormone regulation during physical activities among healthy trained participants. Twenty-two male participants (mean age: 40.27 ± 5.4 years) participated in this study. Two conditions were constructed, namely, a noncompetitive and a competitive running task (RT), which were separated by a 2-week interval. Urine and blood samples were collected prior to and following the running tasks. Noradrenaline (NA), adrenaline (A), dopamine (D), and their metabolites, vanillylmandelic acid (VMA) and homovanillic acid (HVA), were measured from urine, while testosterone levels were analyzed from blood samples. RD was assessed using the Cloninger's Personality Inventory (PI). Mental health was evaluated using the WHO Well-Being, Beck Depression, and Perceived Life Stress Questionnaires. According to our findings, levels of NA, A, D, VMA, and testosterone released underwent an increase following physical exertion, independently from the competitive condition of the RT, while HVA levels experienced a decrease. However, we found that testosterone levels showed a significantly lower tendency to elevate in the competitive RT, compared with the noncompetitive condition (p = 0.02). In contrast, HVA values were higher in the competitive compared with the noncompetitive condition (p = 0.031), both before and after the exercise. Considering the factor RD, in noncompetitive RT, its higher values were associated with elevated NA levels (p = 0.007); however, this correlation could not be detected during the competitive condition (p = 0.233). Among male runners, the NA and testosterone levels could be predicted to the degree of RD by analyzing competitive and noncompetitive physical exercises.
RESUMO
Innovative technologies can support older adults with or without disabilities, allowing them to live independently in their environment whilst monitoring their health and safety conditions and thereby reducing the significant burden on caregivers, whether family or professional. This paper discusses the design of a study protocol to evaluate the acceptance, usability, and efficiency of the SAVE system, a custom-developed information technology-based elderly care system. The study will involve older adults (aged 65 or older), professional and lay caregivers, and care service decision-makers representing all types of users in a care service scenario. The SAVE environmental sensors, smartwatches, smartphones, and Web service application will be evaluated in people's homes situated in Romania, Italy, and Hungary with a total of 165 users of the three types (cares, elderly, and admin).
