The Use of Vibration Training in Men after Myocardial Infarction.

The aim of the study was to evaluate the effects of the applied whole-body vibration training (WBV) as additional training to standard rehabilitation programme on exercise tolerance, evaluated through an exercise test, blood lipid profile, and the changes in selected echocardiographic parameters of patients after myocardial infarction. The study involved 63 males. The subjects were divided into two groups: standard­ST (27) and with vibration training­ST + WBV (36). All the subjects had undergone angioplasty with stent implantation. The standard and with vibration training group carried out a 24-day improvement program comprising 22 training units. Each session consisted of endurance, general stamina, and resistance training. Instead of resistance training, the experimental group performed exercises on the vibration platform. Statistically significant changes in both groups were observed in the parameters of the echocardiographic exercise test, such as test duration (p < 0.001), distance covered (p < 0.001), MET (p < 0.001), VO2max (p < 0.001), and HRrest (p < 0.01). The echocardiographic test revealed significant improvement of Left Ventricular Ejection Fraction in both groups (ST + WBV group p = 0.024, ST group p = 0.005). There were no statistically significant changes in blood lipid profile and body mass and composition.

Indoor cycling training in rehabilitation of patients after myocardial infarction.

BACKGROUND: Standard endurance training used from the second stage of cardiac rehabilitation has many common features with indoor cycling training which is used in fitness clubs. In the study, an attempt was made to evaluate the usefulness of this form of training in a 24-day rehabilitation program for patients after myocardial infarction. The study examined a group of 64 patients (51.34 ± 8.02 years) who were divided into two groups: the IC group (32 patients aged 53.40 ± 4.31 years) with indoor cycling training instead of standard endurance training; and the ST group (32 patients aged 55.31 ± 6.45 years) performing standard training. The level of exercise tolerance (cardiopulmonary exercise testing on a treadmill-Bruce's protocol), hemodynamic indicators of the left ventricle (echocardiography) and blood lipid profile (laboratory test) were assessed. RESULTS: In the IC group there was a significant increase in the test duration (9.21 ± 2.02 vs 11.24 ± 1.26 min; p < 0.001), the MET value (9.16 ± 1.30 vs 10.73 ± 1.23; p = 0.006) and VO2max (37.27 ± 3.23 vs 39.10 ± 3.17 ml/kg/min; p < 0.001). Parallel changes were observed in the ST group, where the following parameters improved: the test duration (9.41 ± 0.39 vs 10.91 ± 2.22; p < 0.001), MET value (8.65 ± 0.25 vs 9.86 ± 1.12; p = 0.002) and VO2max (36.89 ± 6.22 vs 38.76 ± 3.44; p < 0.001). No statistically significant changes were found in the hemodynamic indices of the left ventricle and the lipid profile. Also, the intergroup analysis did not show any statistical significance. CONCLUSION: Based on the research results, it was found that indoor cycling training in the second phase of cardiac rehabilitation is a safe form of therapy and therefore may be an interesting alternative method to the classic bicycle ergometer exercise in the stage of early cardiac rehabilitation.

The Effects of Nordic Walking Compared to Conventional Walking on Aerobic Capacity and Lipid Profile in Women Over 55 Years of Age.

BACKGROUND: The purpose of this study was to investigate the effects of Nordic Walking compared to conventional walking on aerobic capacity, the lipid profile, left ventricular ejection fraction, body mass, and body mass index in women over 55 years old. METHODS: The study was comprised of 74 women over 55 years of age. Participants were randomized to the Nordic Walking (n = 38) or conventional walking (n = 36) training groups. The echocardiogram, treadmill exercise stress test, lipid profile, and body mass were assessed at baseline (pretest) and after 12 weeks (posttest). RESULTS: The authors found a significant main effect over time in duration (effect size [ES] = 0.59, P < .0001), distance covered (ES = 0.56, P < .0001), peak oxygen consumption (ES = 0.43, P < .0001), metabolic equivalent (ES = 0.29, P < .0001), peak heart rate (ES = 0.2, P < .0001), peak diastolic blood pressure (ES = 0.11, P = .0045), total cholesterol (ES = 0.26, P < .0001), and low-density lipoprotein cholesterol (ES = 0.16, P = .0005). The authors did not observe a time versus group interaction or the effect between groups. Post hoc tests revealed significant pretraining to posttraining differences in low-density lipoprotein cholesterol after the Nordic Walking training program and in peak diastolic blood pressure after the conventional walking training program. The heart rate, systolic blood pressure, and diastolic blood pressure at rest, peak diastolic blood pressure, somatic parameters (body mass and body mass index), and left ventricular ejection fraction did not change in either group. CONCLUSIONS: Both training programs resulted in increases in aerobic capacity and decreases in total cholesterol.

The Use of Artificial Hypoxia in Endurance Training in Patients after Myocardial Infarction.

The presence of a well-developed collateral circulation in the area of the artery responsible for the infarction improves the prognosis of patients and leads to a smaller area of infarction. One of the factors influencing the formation of collateral circulation is hypoxia, which induces angiogenesis and arteriogenesis, which in turn cause the formation of new vessels. The aim of this study was to assess the effect of endurance training conducted under normobaric hypoxia in patients after myocardial infarction at the level of exercise tolerance and hemodynamic parameters of the left ventricle. Thirty-five patients aged 43-74 (60.48 ± 4.36) years who underwent angioplasty with stent implantation were examined. The program included 21 training units lasting about 90 min. A statistically significant improvement in exercise tolerance assessed with the cardiopulmonary exercise test (CPET) was observed: test duration (p < 0.001), distance covered (p < 0.001), HRmax (p = 0.039), maximal systolic blood pressure (SBPmax) (p = 0.044), peak minute ventilation (VE) (p = 0.004) and breathing frequency (BF) (p = 0.044). Favorable changes in left ventricular hemodynamic parameters were found for left ventricular end-diastolic dimension LVEDD (p = 0.002), left ventricular end-systolic dimension LVESD (p = 0.015), left ventricular ejection fraction (LVEF) (p = 0.021), lateral e' (p < 0.001), septal e' (p = 0.001), and E/A (p = 0.047). Endurance training conducted in hypoxic conditions has a positive effect on exercise tolerance and the hemodynamic indicators of the left ventricle.

Effectiveness of Resistance Training with the Use of a Suspension System in Patients after Myocardial Infarction.

The aim of the study was to assess the effects of resistance training with the use of a suspension system on exercise tolerance, evaluated through an exercise test, and the changes in selected echocardiographic parameters of patients after myocardial infarction. The study involved 44 males. The subjects were divided into two groups: Standard (20) and Suspension system (24). All the subjects had undergone an angioplasty with stent implantation. The standard and suspension system groups carried out a 24-day improvement program comprising 22 training units. Each session consisted of endurance, general stamina and resistance training. Instead of resistance training, the experimental group made multijoint exercises with a suspension system. Statistically significant changes in both groups were observed in the parameters of the echocardiographic exercise test, such as test duration (p = 0.000), distance covered (p = 0.000), MET (p = 0.000), VO2max (p = 0.000) and SBPrest (p = 0.013). Additionally, SBPmax in the suspension system group improved (p = 0.035). The echocardiographic test revealed significant improvement of Left Ventricular Ejection Fraction in both groups (SP group p = 0.001, standard group p = 0.005). The lipid profile test in the SP group revealed statistically significant improvement of TC (p = 0.003), HDL (p = 0.000) and LDL (p = 0.005). Training with the suspension system had a positive effect on the change of exercise tolerance level, left ventricular function and blood lipid profile.

Effects of Hatha Yoga on Cardiac Hemodynamic Parameters and Physical Capacity in Cardiac Rehabilitation Patients.

PURPOSE: The purpose of the present study was to assess the effect of hatha yoga training that was added to the standard cardiac rehabilitation (CR) program on the cardiac hemodynamic parameters and physical capacity of patients with ST-elevation myocardial infarction (STEMI). METHODS: The study included 70 male patients aged 45-65 yr with STEMI who were treated by angioplasty. Patients were randomized to standard CR (control group) versus standard CR plus hatha yoga (experimental group). The training program lasted for a total of 24 d for each patient, with day 1 and day 24 used for medical examinations (electrocardiogram, spiroergometric submaximal treadmill test, and echocardiography). The remaining 22 d consisted of the actual training. RESULTS: After the CR program the spiroergometric stress test parameters and left ventricular ejection fraction (LVEF) improved in both the experimental and control groups. The most notable changes in echocardiography parameters and physical capacity were in the experimental group. The results showed significant main effect over time, a time-versus-group interaction in LVEF, the duration of the test, and peak oxygen uptake, and a time-versus-group interaction in metabolic equivalents (METs). We also noted the improvement of left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and heart rate over time. CONCLUSION: The results revealed better effectiveness in the CR program with a modified hatha yoga training program. Hatha yoga training could be recommended as an adjunct to standard CR.

Analysis of scoliosis deformation in the Zebris computer study as an assessment of the effectiveness of the FED method in the treatment of idiopathic scolioses.

Idiopathic scoliosis is one of the most difficult problems of contemporary orthopaedics and physiotherapy, and its unknown etiology hinders initiation of effective causative therapy. A tendency for progression of scoliosis, and failure of many conservative treatment methods stimulated a search for new and more effective methods which will not only stop a progress of the deformation, but actually correct it. The FED method is a relatively new, but promising method used for conservative treatment of idiopathic scoliosis. It is based on the use of a special device, which enables corrective forces to act at a level of the scoliotic curve. AIM: The aim of this study was a comparative analysis of effectiveness of idiopathic scoliosis treatment using the FED method versus FITS, during 3 weeks of observations of girls aged 11 to 15 years. MATERIALS AND METHODS: The study was conducted in 60 girls, aged from 11 to 15 years (mean 13.58 ± 1.33 years) randomly qualified which were suffered with double-curve scoliosis of the 2nd degree according to Cobb. According to the randomization, the girls were assigned to two groups based on the therapeutic strategy, the study group of patients treated with the FED method, and the control group treated with the FITS method. The therapy results were evaluated by computer examination of the posture using the Zebris CMS10 system. The degree of the spine deformity in the frontal plane was described with the total scoliotic deformation (SD) angle. RESULTS: In the conducted study, no statistically significant difference was noted between groups for any of the analyzed variables. It means that these groups did not differ statistically in terms of subjects' number, age, type of scoliosis, Cobb angle value for primary and secondary scoliosis, Risser sign, Raimondi rotation, and scoliosis type. Statistically significant differences were found between the two groups for the scoliosis degree, however, after the therapy, the girls treated with the FED method were characterized by a greater improvement in this parameter versus the control group. CONCLUSIONS: Both FED and FITS methods significantly influence the improvement in the scoliotic deformation degree in the Zebris computer examination during a 3-week follow-up; however, when both treatment methods are compared, it can be concluded that the therapy by the FED method is statistically more effective. The treatment of the 2nd degree scolioses with the FED method requires further analyses supplemented with other parameters of postural examination, as well as long-term diagnostics in a larger group of patients.

The use of modern telemedicine technologies in an innovative optimal cardiac rehabilitation program for patients after myocardial revascularization: Concept and design of RESTORE, a randomized clinical trial.

Despite proven efficacy of cardiac rehabilitation (CR) in reducing the all-cause mortality in patients after myocardial revascularization, the penetration of CR, due to patient-related factors and referral rates remains limited. To improve the outcomes, home-based tele-rehabilitation (TR) has been proposed recently. In theory TR enhances the effects of standard CR procedures due to implementation of an intelligent monitoring system designed to ensure optimal training through on-demand transmission of vital signs, aimed at motivating the patients through daily schedule reminders, setting daily goals and creating a platform for mutual feedback. Several meta-analyses assessing various studies comparing these two methods (CR and TR) have proven that they are at least equally effective, with some of the research showing superiority of TR. Although there was a small sample size, lack of long-term follow-up, reporting effects of TR itself, no integration with tools designed for coaching, motivating and promoting a healthy lifestyle constitutes an important limitation. The latter carries a hopeful prognosis for improvement when utilizing a broad-spectrum approach, especially with use of dedicated technological solutions exploiting the fact of a large and yet rapidly increasing penetration of smartphones, mobile PCs and tablets in the population. The above-mentioned findings worked as the basis and rationale for commencing the RESTORE project aimed at developing and delivering state-of-the-art, comprehensive TR for patients after myocardial revascularization and evaluating its molecular aspect in view of how it influences the atherosclerosis progression attenuation. This paper presents the current state and rationale behind the project based on up-to-date TR efficacy data.

Conformity Scores Differentiate Older Hemodialyzed Patients and Patients with Continuous Peritoneal Dialysis.

BACKGROUND Conformity is a psychological variable related to the propensity of an individual to match his or her behavior and opinion to the perceived social and cultural norm, even if these do not represent the true beliefs of the person. The aim of the present study was to investigate whether the psychological variable of conformity is different in two distinct modes of renal replacement therapy (RRT) in end-stage renal disease (ESRD). MATERIAL AND METHODS A total of 56 hemodialyzed patients (HD group), 45 continuous ambulatory peritoneal dialysis patients (CAPD group) and 62 healthy volunteers (CONTR group) were enrolled in the study. The Social Appraisal Questionnaire (SAQ) was employed, and chart review was performed to collect clinical data. RESULTS When age was not a factor, the conformity measure was significantly higher in the HD group compared with the CAPD and CONTR groups. The lowest conformity was found in healthy participants who were asked to imagine an acute medical problem. The highest conformity was found in older HD and CAPD patients. CONCLUSIONS Being chronically ill and having adaptable views may be more favorable traits for coping with ESRD in dialyzed patients, especially in elderly HD patients. On the other hand, conformity can be deleterious if CAPD patients decide to overlook certain facts or not confront the medical aspects of their condition.

Ketamine affects in vitro differentiation of monocyte into immature dendritic cells.

BACKGROUND: Monocytes (MOs) have the unique ability to differentiate into immature dendritic cells (iDCs) (MO→iDC) under the influence of interleukin-4 and granulocyte-monocyte colony-stimulating factor (IL-4&GM-CSF). In this study, the authors investigated the influence of ketamine on the process of MO→iDC. METHODS: iDCs were cultured from MO obtained from 36 subjects in the presence of IL-4 and GM-CSF and ketamine at 100, 10, and 1 µg/ml for 5 days. In some of the experiments, the authors used nonspecific N-methyl-D-aspartate (NMDA) receptor antagonist MK-801, NMDA, or a neutralizing antibody for transforming growth factor ß (TGFß). The expression of surface markers and functional assays were used to assess the effect of ketamine on IL-4&GM-CSF-stimulated MO. IL-4&GM-CSF-stimulated MO's supernatants were assessed for cytokine levels. RESULTS: Ketamine at 10 µg/ml, and higher concentrations, diminished the expression of CD1a on IL-4&GM-CSF-stimulated MO and retarded both their ability to process DQ ovalbumin and mixed lymphocyte reaction stimulation. The addition of ketamine to IL-4&GM-CSF-differentiated MO resulted in the persistent expression of CD14 and unchanged expression of CD86 and CD206. The phagocytic abilities of IL-4&GM-CSF-differentiated MO were not changed by ketamine. MK-801, a nonselective NMDA agonist, mimicked ketamine's effect on MO→iDC differentiation. Adding exogenous NMDA to IL-4&GM-CSF-stimulated MO in the presence of ketamine partially restored the level of CD1a. TGFß was elevated in supernatants of IL-4&GM-CSF-stimulated MO in the presence of ketamine. Adding neutralizing TGFß antibody or TGFßR1 blocker (SB431542) resulted in the full recovery of MO→iDC, despite the presence of ketamine. CONCLUSIONS: Ketamine diminishes the process of MO→iDC in vitro. This is mediated via NMDA-dependent mechanisms and TGFß.

Denial Defense Mechanism in Dialyzed Patients.

BACKGROUND: It is a struggle to identify the most adaptive coping strategies with disease-mediated stress. Here, we hypothesize that intensity of coping strategies, including denial, in patients with end-stage renal disease (ESRD), varies with type of renal replacement therapy (RRT). MATERIAL AND METHODS: We enrolled 60 in-center hemodialyzed patients (HD) and 55 patients treated with continuous ambulatory peritoneal dialysis (CAPD). We administered the Coping Inventory with Stressful Situation, Profile of Mood States, and Stroop Anxiety Inventory to measure patient coping strategies in the context of their ESRD. Denial defense mechanism was measured via the IBS-R/ED. The Nottingham Health Profile was used to evaluate self-perceived quality of life. Serum potassium, urea, creatinine, phosphorus, calcium, albumin, and hematocrit were utilized as the measurements of adequacy of dialysis. RESULTS: HD patients had higher self-reported intensity of denial mechanism and avoidance-oriented strategies versus CAPD patients. Because a single strategy is almost never employed, we conducted cluster analysis. We identify 3 patterns of coping strategies using cluster analysis. "Repressors" employed denial and avoidance strategies and were predominant in HD. The second cluster consists of subjects employing predominantly task-oriented strategies with equal distribution among dialyzed patients. The third cluster encompassed a small group of patients who shared higher intensity of both denial and task-oriented strategies. Health-related outcome, anxiety, and mood profile were similar across all patients. CONCLUSIONS: HD patients predominantly used "repressive" strategies. Patients on RRT utilized denial and avoidance-based strategies to achieve satisfactory outcome in terms of perceived quality of life. We conclude that these coping mechanisms that were previously thought to be inferior are beneficial to patient compliance with RRT.

D-Galactosamine Intoxication in Experimental Animals: Is it Only an Experimental Model of Acute Liver Failure?

BACKGROUND: Short-term administration of Galactosamine to experimental animals causes liver damage and acute liver failure (ALF), as well as acute renal failure in some cases. The aim of our study was to describe kidney disorders that developed in the course of galactosamine-induced liver failure. MATERIAL AND METHODS: Sprague-Dawley rats were randomly divided into 2 groups: a study group administered galactosamine intraperitoneally and a control group administered saline. RESULTS: All the animals in the study group developed liver damage and failure within 48 h, with significant increase of alanine (p<0.001), aspartate aminotransferases (p<0.0001), bilirubin (p<0.004), and ammonia (p<0.005) and decrease of albumin (p<0.001) concentrations. Acute renal failure was observed in all test animals, with a significant increase in creatinine (p<0.001) and urea (p<0.001) concentrations and a decrease in creatinine clearance (p<0.0012). Moreover, osmotic clearance (p<0.001), daily natriuresis (p<0.003), and fractional sodium excretion (p<0.016) decreased significantly in this group of animals. The ratio of urine osmolality to serum osmolality did not change. Histopathology of the liver revealed massive necrosis of hepatocytes, whereas renal histopathology showed no changes. CONCLUSIONS: Acute renal failure that developed in the course of galactosamine-induced ALF was of a functional nature, with the kidneys retaining the ability to concentrate urine and retain sodium, and there were no renal changes in the histopathological examination. It seems that the experimental model of ALF induced by galactosamine can be viewed as a model of hepatorenal syndrome that occurs in the course of acute damage and liver failure.

Low back pain in adolescents. An assessment of the quality of life in terms of qualitative and quantitative pain variables.

BACKGROUND: Information concerning low back pain in adolescents with scoliosis is rather limited in literature. While the epidemiology of back pain at the age of adolescence has been described extensively, studies evaluating the effects of therapeutic interventions are still sparse. MATERIAL AND METHOD: The study was conducted in two groups with juvenile idiopathic scoliosis Io. The clinical group was 21 persons with low back pain and the control group was 11 persons without pain. In order to assess the quality of life and the level of pain We used the abridged version of WHOQOL (World Human Organizations Quality of Life questionnaire) and MPQSF (Short Form of McGill Pain questionnaire). The treatment consisted of a combination of manual therapy and rehabilitation exercises. RESULTS: We obtained a significant improvement in the area of the physical health: 7.17 in the clinical group (p = 0.000613); 6.12 for females (p = 0.015400); 9.19 for males (p = 0.022311). The assessment of the quality of life was different between the clinical and the control groups. The decrease in pain in the clinical group was 5.71 (p = 0.000132), 5.93 for females (p = 0.001474) and 5.29 for males (p = 0.027709). Data represents more than a double decrease in strong and moderate pain. CONCLUSION: A combination of rehabilitation exercises and soft manual therapy is effective in reducing the low back pain in adolescents and enhancing the somatic facet of the quality of life.

[Surveyed pregnant women's opinion concerning the importance of the participation in the school of birth as a form of preparation for childbirth]. / Opinia badanych kobiet w ciazy dotyczaca waznosci uczestnictwa w szkole rodzenia jako formy przygotowania do porodu.

The purpose of the research was the questionnaire evaluation of 76 pregnant women-primiparas concerning the importance of the participation in the school of birth as a form of preparation for childbirth. The women were planning their pregnancy at the age of between 20 and 30. The pregnant women declared the importance of physical activity during their pregnancy, however, it did not resulted in the participation in the school of birth.

Effect of nitric oxide pathway regulation on water/sodium balance and renal function in a rodent model of acute liver and renal failure.

BACKGROUND: The pathomechanism of acute hepatorenal syndrome (HRS), a particular form of acute renal failure that occurs in the course of acute liver injury, is still poorly understood. The aim of our study was to estimate the influence of the activation and inhibition of the nitric oxide pathway on the water/sodium balance and development of acute renal failure in the course of HRS. MATERIAL AND METHODS: We used male Sprague-Dawley rats in the acute galactosamine (Ga1N) model of HRS. The nitric oxide synthase (NOS) inhibitors L-NAME and L-arginine were administered intraperitoneally before and after liver damage. RESULTS: HRS developed in all tested groups. L-NAME increased osmotic clearance and urine volume more effectively before liver injury. Furthermore, administration of L-NAME increased creatinine clearance both before and after Ga1N injection. A double dose of L-NAME did not yield further improvement before Ga1N injection, but improved creatinine clearance after Ga1N intoxication. Injection of L-arginine increased sodium excretion and urine volume, but only after liver injury. Moreover, L-arginine injected after Ga1N caused significant improvement of the creatinine clearance in a dose-dependent manner. CONCLUSIONS: Our study shows that inhibition of the nitric oxide pathway improves parameters of water and sodium balance and prevents development of acute renal failure in the course of acute liver injury and liver failure. Activation of the nitric oxide system also has a favorable influence on water/sodium balance and renal failure, but only after liver injury.

The perception of the illness with subsequent outcome measure in more favorable in continuos peritoneal dialysis vs hemodialysis in the framework of appraisal model of stress.

The aim of the study was to use the appraisal model of stress to compare hemodialysis (HD) and continuous peritoneal dialysis (CAPD) patients with special focus on the perception of end-stage renal disease and subsequent emotional profile and health related quality of life (HQoL) in. We hypothesize that different circumstances related to both modes of therapies will result in dissimilar perception of chronic illness with subsequent changes in emotional profile and heath related quality of life. The total of 88 patients with end stage renal disease (ESRD) enrolled in hemodialysis (n=52; HD) or continuous peritoneal dialysis (n=36; CAPD) were given a battery of psychological tests: The Profile of Mood States, The Nottingham Health Profile, The Stress Situation Assessment Questionnaire, The Social Appreciation Questionnaire and The Situation and Trait and Anxiety Inventory. All patients perceived ESRD in terms of a loss and a threat. Moreover, CAPD patients evaluated ESRD as a challenge. Despite different perception of ESRD no significant difference in the level of fear, anxiety or emotional profile was found. Both HD and CAPD patient were reported more fatigue/inertia and confusion/bewilderment than control groups. The main health related complaints were similar in both ESRD patients with major complaints of sleeping disturbances, motor limitations and lack of energy. From the psychological point of view, CAPD treatment seems more like challenge to the enrolled patient which is positive outcome. Despite different appraisal of stress mood and health related complaints were similar in both groups. This may be a result of optimal regulation of cognitive perception of the stress depending on the circumstances of therapy.

Age-related differences in the quality of life in end-stage renal disease in patients enrolled in hemodialysis or continuous peritoneal dialysis.

BACKGROUND: The aim of the present study was to compare the experience elderly and younger patients in terms of emotional status, disease perception, methods of coping with the end-stage renal disease (ESRD) stress, and health-related quality of life in 2 different settings of renal replacement therapy: hemodialysis (HD) and continuous ambulatory peritoneal dialysis programs (CAPD). Specifically, we hypothesized that younger people will more frequently use goal-oriented strategies to cope with illness-related stress and elderly patients will use more strategies related to the control of emotion. MATERIAL AND METHODS: A total of 69 HD patients, 40 CAPD patients, and 89 healthy volunteers were analyzed. The Situation and Trait Anxiety Inventory, the Profile of Mood States, the Cognitive Stress Appraisal Questionnaire, and the Nottingham Health Profile were used to assess anxiety, long-term emotional status, coping mechanisms, and health-related quality of life. Data were collected on several biochemical and demographic variables. RESULTS: Our study revealed that younger and elderly people on dialysis faced quite different problems. Younger people in both RRT groups had statistically higher assessment of ESRD as loss or challenge and they more frequently used distractive and emotional preoccupation coping strategies. Depression, confusion, and bewilderment dominate the emotional status of both patient populations, especially in the younger cohort. Both HD(young) and CAPD(young) patients complained more about lack of energy, mobility limitations, and sleep disturbances as compared to their elderly HD and CAPD counterparts. CONCLUSIONS: There are different needs and problems in younger and elderly patients on renal replacement therapy. Younger people required more ESRD-oriented support to relieve their health-related complaints to the level observed in their peers and needed extensive psychological assistance in order to cope with negative emotions related to their disease.

Pulmonary physiotherapy in patients with bronchial asthma.

In the present study we investigated the effectiveness of a 3-month breathing exercise program in patients with mild-to-moderate asthma, as assessed from spirometric indices. The study group consisted of 28 asthma patients (mean age of 43 years). The physiotherapy program consisted of 45-min exercise sessions, performed twice a week for 3 months. We measured the flow-volume indices (FEV(1), FVC, PEF, MEF(50)) before and after the exercise sessions at the beginning and end of the physiotherapy program. In addition, the patients measured their personal best peak expiratory flow (PEF). We found no significant changes in spirometric indices before and after an exercise session either at the beginning or end of the physiotherapy program, although there was a tendency for lower values after the exercise sessions at both beginning and end of the physiotherapy program. There was a significant decrease in PEF after an exercise session at the beginning of the physiotherapy program; this decrease lost significance after completion of the physiotherapy program. However, PEF values were greater both before and after the exercise sessions at the end of the physiotherapy program compared with the corresponding sessions before the program. We conclude that the breathing exercise program employed in the study failed to appreciably improve lung function in asthmatic patients. However, there was no asthma exacerbations observed during the conduction of breathing exercise program, which underscores the need for pulmonary rehabilitation in asthma treatment.

Albuminuria and hyperhomocysteinemia as cardiovascular risk factors in potentially healthy soldiers: A long-term observation.

BACKGROUND: To assess the relations between albuminuria and selected cardiovascular risk factors. MATERIAL/METHODS: The study population comprised 200 apparently healthy soldiers aged 28.8±8.1, observed for 36 months. RESULTS: Albuminuria was revealed in 9% of the studied group at the beginning of the study and in 12.7% at the end of the observation. Albumins increased from 97.0±61.0 mg/24 hours to 165.0±25.7 mg/24 hours after 36 months of observation. The increase of diastolic blood pressure, body mass, C-reactive protein (CRP), and low-density lipoprotein (LDL) was found in the "albuminuria subgroup" after 3 years of observation. This subgroup also presented significantly higher homocysteine and CRP serum concentrations in comparison with the "non-albuminuria group" in the first phase of the study and after 3 years of follow-up. CONCLUSIONS: Albuminuria was found to be a relatively frequent and persistent abnormality in the studied group. The study demonstrated the relationship between the occurrence and the severity of albuminuria and selected biochemical and demographic cardiovascular risk factors. Determination of albuminuria is a useful, early marker of cardiovascular risk in young male professional soldiers.

Aberrant function and differentiation of monocytes in end stage renal disease.

Patients with end stage renal disease (ESRD) suffer from many disturbances of the immune system. These immunopathologies are related to the higher failure of vaccination, and increased prevalence of infections and neoplasms. In the presented article, we review the current data regarding the role of monocytes in immune dysfunctions which are observed in terminal renal failure. As monocytes play a pivotal role in regulating the function of the immune system, their dysfunction can have a profound effect on the immune system and may lead to accelerated arteriosclerosis and deteriorating overall health conditions. More specifically, we suggest that peripheral blood monocytes in patients with ESRD are chronically activated, and their functional and phenotypical features resemble those of inflammatory macrophages. This state of chronic inflammation is unfavorable for dendritic cells and consequently, the prevalence of dendritic cells is reduced. As these effects are consistent across different modes of dialysis, they are probably mediated by the uremia itself.
