Introduction. The clinical significance of cognitive impairments remaining in patients with acute cerebrovascular accidents (stroke) in the second rehabilitation period actualizes the need for their correction. The technique of cognitive training shows a high degree of cognitive function recovery, but negative emotional states that may occur in patients during rehabilitation may reduce its positive effect. In this regard, the use of biofeedback (BFB) training to stabilize the patients’ psycho-emotional state before cognitive training can increase its effectiveness.Purpose. To evaluate the impact of BFB-training on the effectiveness of cognitive training in patients with acute cerebrovascular disorders in the second rehabilitation period.Design. 41 post-stroke patients (ischemic stroke) in their late recovery period with varying degrees of cognitive impairments, not reaching the level of dementia, completed a course of standard rehabilitation and psychological treatment, including cognitive training sessions. Of these, 20 patients (the experimental group), before cognitive training, additionally underwent a BFB-training based on the skin conductance parameter. Psychodiagnostic evaluation conducted before and after the rehabilitation course included a study of visual and auditory-speech memory, volume, distribution, and attention switching, the level of depression, as well as unconscious and conscious anxiety.Results. After the course of rehabilitation and psychological treatment, the experimental group showed a statistically significant improvement in all cognitive functions and indicators of psycho-emotional state. Positive dynamics in the control group is observed only in the cognitive sphere. The level of cognitive functions in the experimental group after the rehabilitation course was significantly higher than in the control one.Conclusions. An additional inclusion of BFB-training in the course of rehabilitation and psychological treatment helps to increase the effectiveness of cognitive training by stabilizing the psycho-emotional state, as well as by providing a positive impact of biofeedback methods on cognitive functions.

The Impact

Introduction: Previous studies demonstrated that forced and voluntary exercise had ameliorative effects on behavioral tasks followed by Sleep Deprivation (SD) in intact female rats. The main goal of this research was evaluating the impact of voluntary exercise on cognitive functions while SD and ovariectomization is induced in female wistar rats. Methods: The rats were anesthesized combining dosage of ketamine and xylazine. Then, both ovaries were eliminated and 3 weeks after surgery the animals entered the study. The exercise protocol took 4 weeks of voluntary exercise in a wheel which was connected to home cage. For inducing a 72 hours deprivation the multiple platforms was applied. The cognitive functions were studied by exploiting the Morris Water Maze (MWM) and Novel object recognition tests. Anxiety was evaluated by open field test and corticostrone measurement was carried out by ELISA method. One-way and two-way ANOVA and repeated measures were utilized for data analysis and P<0.05 was considered statistically significant. Results: We observed significant spatial and recognition learning and memory impairments in OVX sleep-deprived rats compared to the control group and voluntary exercise alleviated the SD-induced learning and memory defects. Conclusion: We concluded that voluntary exercise can improve cognitive impairments followed by SD in OVX female rats.

IntroductionCognitive impairment is considered to be a result of oxidative stress and disturbances in inflammatory status. Whole-body cryotherapy (WBC), which is a short exposure to extremely low temperatures, probably regulates the release of cytokines and nitric oxide. The hypothesis is that WBC may be useful in the therapy of mild cognitive impairments (MCI).AimsThe effect of the whole-body cryotherapy (WBC) on cognitive impairments was investigated.ObjectivesIn this study the observation of several biological factors and cognitive functions were conducted to analyse the WBC influence on cognitive deficits.MethodsPeople with MCI participated in 10 WBC sessions divided for experimental group (−110 °C till −160 °C) or control group (−10 °C till −20 °C). The MoCa test (scores 26 and lower) was used for inclusion criteria. Cognitive functions were measured with: TYM, DemTect and SLUMS at baseline and in follow-up. Biological factors (cytokines, BDNF, NO) were also assessed.ResultsIt was shown that memory domains in experimental group improved after WBC sessions. Also modulatory effect on inflammatory mediators in plasma was shown. The results of this study consist of the comparison of experimental and control groups regarding to cognitive functions as well as biological factors.ConclusionsWhole-body cryotherapy may be supposed to improve cognitive functions in MCI patients. The modulatory effect of WBC on immunological response may be considered as one of possible mechanisms of its action. However, there is no confirmation how long the effects resist so further investigations are needed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The article deals with the state of cognitive functions (memory, attention and thought process) and asthenic disorders in stroke patients in the process of physical rehabilitation and pharmacotherapy. The study used conventional methods for determining the state of cognitive functions. To improve cognitive abilities in the process of physical rehabilitation in the experimental group of patients, traditional methods and special physical exercises in the form of training tasks for memory, attention and thought processes were used. In the control group of patients only traditional methods of restoration of cognitive functions were used. Both groups of patients took the same drugs to improve cognitive function and relieve symptoms of cerebrogenic asthenia, using classic nootropic drugs (Pyracetam, Phenotropil, Vinpotropil), peptide drugs (Cortexin, Cerebrolysin, Noopept, Semax), antidepressants and tranquilizers (benzodiazepines and non-benzodiazepine). It is determined that the most important indicator of memory quality is short-term memory. In the experimental group in the process of physical rehabilitation revealed an improvement in this memory in 50% of patients, the deterioration of this indicator in 34% of persons, and 16% memory remained at the same level. Short-term memory indices in post-stroke patients of the control group are lower and correspond to: improvement – in 35%, deterioration – in 40%, remained at the same level in 25% of patients. Since the rate of short-term memory is 7 ± 2 units of information, the study showed that in all patients after a stroke, the indicators of storing information in short-term memory have become normal. The study of attention stability revealed that in the control group of patients it is worse than in the experimental group, and that the stability of attention does not depend on the experience of the post-stroke state. Patients with 3 years of post-stroke experience show the same results as patients with 6-month stroke. The study of inductive thinking showed that in both groups of patients it is in good condition. As for the indicators of practical mathematical thinking, 83% of the participants coped with the task in the experimental group, and 17% failed. In the control group, 57% of patients coped with this task, and 43% failed. Only 50% of the patients in the experimental group and 42% of the control group coped with a more difficult task in this type of thinking. The same results were obtained in persons without stroke. This shows that the more difficult tasks of identifying this type of thinking are difficult for people after a stroke. It can be concluded that the mental processes of a person after a stroke are in optimal condition.

Background: The necessity of improve the life quality in elderly people is well-known. The aim of this study was to determine the effects of physical and cognitive training programs, as well as their combination on the cognitive functions and physical capacities in women over 80 years old. Methods: Forty-three women took part in this study (80.86 ± 5.03 years). They were divided into four groups (three experimental groups and one control group). Experimental group 1 performed cognitive training. Experimental group 2 did physical–cognitive training, and Experimental Group 3 accomplished physical training. All of training programs had duration of eight weeks (five sessions of 60 min per week). We measured cognitive variables with the Stroop test, D2 test, and Trail Making test. Physical variables were measured with handgrip strength, Minute Step Test, and visual–acoustic reaction time. Results. Control group reduces his physical and cognitive capacities, while the three experimental groups increase these capacities. We found a strong correlation between the increase of physical and cognitive capacities. Conclusion: Eight weeks of training physical, cognitive or mixed, increased physical and cognitive functions of elderly people which may reduce the negative effects of the aging process.

Introduction:Psychological impact of Therapeutic Patient Education (TPE) for dialysis patients is rarely evaluated since the focus of many studies is on medical variables (i.e., adherence).Objectives:The aims of this study were: 1) to estimate the impact of a TPE program on knowledge, depression and anxiety, 2) to examine change in knowledge as a mediator of the effects of a TPE program on mental health.Method:This study was conducted in three hemodialysis units and comprised two groups: an experimental group with education and a control group with routine care. The program was based of 5 educative sessions. Knowledge, depressive and anxious symptoms were assessed with self-reported outcomes measured before and 3 months after the program.Results:The sample comprised 125 patients. Knowledge about vascular access and nutrition (p < 0.01) and depressive symptoms increased in the experimental group (p < 0.01). Analysis of mediation showed that changes in knowledge about vascular access were a significant mediator of the effects of the program on depressive symptoms (F = 4.90;p = 0.01).Discussion:Knowledge acquired during an educational program could lead to an emotional change. Improving knowledge often leads to an awareness of the risks that can modify the psychological state of patients by reminding them of their vulnerability. This study shows that it is required to be attentive to the way of transmitting knowledge. It’s necessary adapting this transmission to the needs of patients and promoting the acquisition of psychosocial competence too.Conclusion:This study shows that knowledge acquired during an educational program can lead to an emotional change in the short term. A long-term follow-up of the population should be interesting to observe these emotional effects.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

The present study aimed to investigate the effects of geometry instruction activities conducted in nature based on modeling, game-based, and cooperative learning methods on achievement, mathematical motivation, and visual mathematical literacy perceptions of third-grade elementary school students. The present study is a quantitative study conducted with a pre-test/post-test experimental design with a control group. The study was conducted with 61 students (35 students in the experimental group and 26 students in the control group). Modeling-, game-, and collaborative learning-based activities were conducted with the students in the experimental group. It was determined that the achievements of students who were instructed with modeling-based activities in geometry were high when compared to that of the students instructed with collaborative learning- and game-based methods, and those in the control group where no intervention was applied. This group was followed by the game-based and collaborative learning groups. Based on the variable of motivation, the mean motivation of the students in the modeling group was higher when compared to that of the students in the collaborative learning, game-based, and conventional instruction groups. This group was followed by the collaborative and game-based learning groups. Also, based on the visual mathematical literacy perception variable, the mean visual mathematics literacy perception of the students in the collaborative learning group was higher when compared to that of the students in the groups where the modeling, game-based, and conventional instruction methods were used. This group was followed by the modeling and game-based learning groups.

Objective To evaluate the effectiveness of cognitive training in improving tinnitus bother and to identify predictors of patient response. Study Design Prospective open-label randomized controlled trial. Setting Online. Methods Participants were adults with subjective idiopathic nonpulsatile tinnitus causing significant tinnitus-related distress. The intervention group trained by using auditory-intensive exercises for 20 minutes per day, 5 days per week, for 8 weeks. The active control group trained on the same schedule with non–auditory intensive games. Surveys were completed at baseline, 8 weeks, and 12 weeks. Results A total of 64 participants completed the study. The median age was 63 years (range, 25-69) in the intervention group and 61 years (34-68) in the control group. Mixed model analysis revealed that within-subject change in Tinnitus Functional Index in the intervention group was not different than the control group, with marginal mean differences (95% CI): 0.24 (–11.20 to 10.7) and 2.17 (–8.50 to 12.83) at 8 weeks and 2.33 (–8.6 to 13.3) and 3.36 (–7.91 to 14.6) at 12 weeks, respectively. When the 2 study groups were compared, the control group had higher Tinnitus Functional Index scores than the intervention group by 10.5 points at baseline (95% CI, –0.92 to 29.89), 8.1 at 8 weeks (95% CI, –3.27 to 19.42), and 9.4 at 12 weeks (95% CI, –2.45 to 21.34). Conclusion Auditory-intensive cognitive training was not associated with changes in self-reported tinnitus bother. Given the potential for neuroplasticity to affect tinnitus, we believe that future studies on cognitive training for tinnitus remain relevant.

Writing is an intricate process that encompasses various factors and is a key skill for English as a Foreign Language (EFL) students. Thus, writing assignments are vital for any curriculum. One of the essential aspects of effective writing includes good grammar knowledge. Advocates of process writing argue that a free-writing journal is a practical approach to teaching EFL students writing. This study is intended to examine the impact of the free-writing journal on EFL learners. This study was conducted on 80 students from a writing course at the University. Thirty-five students were randomly selected to join the free-writing program—the experimental group—and 45 students were kept in their regular structured writing program—the control group. The experimental group selected topics of interest to them and was encouraged to write in English freely without concern for errors, whereas the control group followed a regular structured writing program where the topics were selected for them and they wrote following a clear guideline. Five major areas were investigated to evaluate students’ progress: the number of words written, spelling, capitalization, subject-verb agreement, and punctuation. The researcher conducted semi-structured interviews with 10 students of the experimental group to elicit their perception of the free-writing program. According to the analysis, students in the free-writing program acquired better grammar acquisition than the control group. The researcher also observed students’ perception of free-writing at the end of the study and found that free-writing improved their writing skills.
