Molecular nutrition in life course perspective: Pinpointing metabolic pathways to target during periconception.

Lifecourse nutrition encompasses nourishment from early development into parenthood. From preconception and pregnancy to childhood, late adolescence, and reproductive years, life course nutrition explores links between dietary exposures and health outcomes in current and future generations from a public health perspective, usually addressing lifestyle behaviours, reproductive well-being and maternal-child health strategies. However, nutritional factors that play a role in conceiving and sustaining new life might also require a molecular perspective and recognition of critical interactions between specific nutrients and relevant biochemical pathways. The present perspective summarises evidence about the links between diet during periconception and next-generation health and outlines the main metabolic networks involved in nutritional biology of this sensitive time frame.

Apelin as a Potential Regulator of Peak Athletic Performance.

Apelin, as a cardiokine/myokine, is emerging as an important regulator of cardiac and skeletal muscle homeostasis. Loss of apelin signaling results in premature cardiac aging and sarcopenia. However, the contribution of apelin to peak athletic performance remains largely elusive. In this paper, we assessed the impact of maximal cardiorespiratory exercise testing on the plasma apelin levels of 58 male professional soccer players. Circulating apelin-13 and apelin-36, on average, increased transiently after a single bout of treadmill exercise; however, apelin responses (Δapelin = peak - baseline values) showed a striking interindividual variability. Baseline apelin-13 levels were inversely correlated with those of Δapelin-13 and Δapelin-36. Δapelin-13 showed a positive correlation with the maximal metabolic equivalent, relative maximal O2 consumption, and peak circulatory power, whereas such an association in the case of Δapelin-36 could not be detected. In conclusion, we observed a pronounced individual-to-individual variation in exercise-induced changes in the plasma levels of apelin-13 and apelin-36. Since changes in plasma apelin-13 levels correlated with the indicators of physical performance, whole-body oxygen consumption and pumping capability of the heart, apelin, as a novel exerkine, may be a determinant of peak athletic performance.

Comparative Effectiveness of 4 Exercise Interventions Followed by 2 Years of Exercise Maintenance in Multiple Sclerosis: A Randomized Controlled Trial.

OBJECTIVE: To determine the effects of exergaming (EXE) on quality of life (QOL), motor, and clinical symptoms in multiple sclerosis (MS). We compared the effects of EXE, balance (BAL), cycling (CYC), proprioceptive neuromuscular facilitation (PNF), and a standard care wait-listed control group on clinical and motor symptoms and quality of life (QOL) in people with MS (PwMS) and determined the effects of subsequent maintenance programs for 2 years in a hospital setting. DESIGN: A randomized controlled trial, using before-after test design. SETTING: University hospital setting. PARTICIPANTS: Of 82 outpatients with MS, 70 were randomized (N=70), and 68 completed the study. INTERVENTIONS: The initial high-intensity and high-frequency interventions consisted of 25 one-hour sessions over 5 weeks. After the 5-week-long initial intervention, the 2-year-long maintenance programs followed, consisting of 3 sessions per week, each for 1 hour. MAIN OUTCOME MEASURES: The primary outcome: Multiple Sclerosis Impact Scale (MSIS-29). SECONDARY OUTCOMES: Measures 5 aspects of health-related QOL (EuroQol 5-Dimension questionnaire), Beck Depression Inventory, 6-minute walk test (6MWT), Berg Balance Scale (BBS), Tinetti Assessment Tool (TAT), and static BAL (center of pressure). RESULTS: MSIS-29 improved most in EXE (11 points), BAL (6), and CYC (6) (all P<.05). QOL improved most in EXE (3 points), CYC, and BAL (2) (all P<.05). TAT and BBS improved significantly (P<.05) but similarly (P>.05) in EXE, BAL, and CYC. 6MWT improved most in EXE (57m), BAL (32m), and CYC (19m) (all P<.001). Standing sway did not change. Maintenance programs further increased the initial exercise-induced gains, robustly in EXE. CONCLUSIONS: A total of 25 sessions of EXE, BAL, CYC, and PNF, in this order, improved clinical and motor symptoms and QOL, and subsequent 2-year-long thrice weekly maintenance programs further slowed symptom worsening and improved QOL. EXE was the most and PNF was the least effective to improve clinical symptoms, motor function, and QOL in PwMS.

The development of a reliable and valid instrument to measure the osteoporosis-related knowledge: validation of the Hungarian version of Osteoporosis Knowledge Assessment Tool (OKAT).

BACKGROUND: Osteoporosis is one of the most common chronic musculoskeletal diseases. Osteoporosis-related knowledge is an important contributor in to prevent osteoporosis. There is no validated reliable questionnaire to measure the knowledge in Hungary. The aim of the study was to validate the Osteoporosis Knowledge Assessment Tool (OKAT) Hungarian version. METHODS: The research was a randomized validation study of a new Hungarian language instrument. The questionnaire was administered to 557 randomly selected healthy women (age between 25 and 44 years) from December 2018 to July 2019 in Baranya county, Hungary. The reliability was examined by the Flesch reading ease and McNemar's test. We examined item discrimination and item-total correlations, inter-item consistency (Cronbach's alpha coefficient) and principal component factor analysis. RESULTS: Significant differences (p <  0.001) were reported between total scores and the age categories. Significant (p <  0.001) correlation (r = 0.25) was found between the education level and the knowledge. Significantly (p <  0.001) higher knowledge were found in health care profession (14.53 ± 3.58) than the non-health care profession (9.99 ± 4.04). Participants with osteoporosis or fracture in family history had better knowledge (p <  0.001). Flesch reading ease was 44, the questionnaire had a Ferguson's sigma of 0.94 and a Cronbach's alpha of 0.81. There were no negative inter-item correlations psychometric properties of the OKAT, all items had more than 70% of correlations (p <  0.001). CONCLUSIONS: The Hungarian version of the Osteoporosis Knowledge Assessment Tool is a reliable and objective questionnaire to measure women's knowledge in Hungary.

Comparative analysis of sports consumption habits in Hungary, Poland and Germany.

BACKGROUND: The so-called sports consumption models are looking for the factors that influence the sports spending of households. This paper aims to examine the Hungarian, Polish and German households' sports expenditures which can be an important indicator of physical activity and sporty lifestyle. METHODS: Surveying of households in three countries (Hungary, Poland and Germany) has been conducted with a self-designed questionnaire. We have used descriptive and bivariate non-parametric and parametric statistical methods: (1) χ2 test, Mann-Whitney test and Kruskal-Wallis test for checking the relationship between sociodemographic and physical activity variables and (2) independent sample t-test and ANOVA for checking the differences in sports expenditures. RESULTS: Our research concluded that men, especially previous athletes, exercise more than women and those who have no history as registered athletes. The choice of sports venues is obviously different between the countries in the sample. Members of the study population spend the most on sports services while they spend the least on sports equipment. German households have the highest spending rates compared to the other two countries. CONCLUSIONS: Results are in line with our previous research findings and with other literatures. The difference in preferences of sports venues could have the reason of different supply of sports clubs or the different living standards too. It needs further researches to clear it. Material wealth, income level and sport socialisation can be a determining factor regarding the level of sports spending.

Multicausal analysis on psychosocial and lifestyle factors among patients undergoing assisted reproductive therapy - with special regard to self-reported and objective measures of pre-treatment habitual physical activity.

BACKGROUND: National, regional and global trends in prevalence of infertility indicate its public health importance, however it effects various life dimensions of individuals and couples as well. Lifestyle habits may counteract with these factors. The aim of the study was the multicausal analysis of psychosocial and lifestyle factors undergoing assisted reproductive therapy (ART) with special regard to pre-treatment habitual physical activity (PA). METHODS: In a cross-sectional, observational cohort study on ART patients (N = 60, age 34.6 ± 5.2 years, BMI 24.2 ± 4.9 kg/m2) with follow up on outcome measures a detailed description was given on PA patterns (ActriGraph GT3X, GPAQ-H) and on general and infertility related distress (BDI-13, FPI). RESULTS: Respondents reported normal mood state (BDI-13) but moderately high infertility-related distress (FPI) in Social- and very high distress in Sexual Concern. It was revealed that time spent with recreational PA (RPA) could counteract with infertility-related distress (Social Concern R = -0.378, p = 0.013; Relationship Concern R = -0.365, p = 0.019). In the presence of clinical pregnancy GPAQ-H RPA MET was significantly higher (p = 0.048), in the non-pregnant group cumulative values and work-related PA were higher. Correlations could be found between RPA time and the number of oocytes (R = 0.315, p = 0.045), matured oocytes (R = 0.339, p = 0.030) and embryos (R = 0.294, p = 0.062) by women who reached at least 150 min RPA (GPAQ-H). Multivariate linear regression revealed that the number of oocytes was positively influenced by the GPAQ-H recreation MET (R2 = 0.367; F = 10.994, p = 0.004; B = 0.005, p = 0.004, B Constant = 4.604). Regarding the number of embryos (R2 = 0.757, F = 17.692, p < 0.001, B Constant = 1.342) positive relationship was found with GPAQ-H RPA MET (B = 0.004, p < 0.001) and negative with BMI (B = -0.167, p = 0.038). It was disclosed (R2 = 0.958, F = 408.479, p < 0.001) that higher Very Vigorous Activity (ActiGraph) was accompanied with higher hCG (B = 63.703, p ≤ 0.001). However, time spent with moderate PA (GPAQ-H) (B = 0.002, SE = 0.001, Wald = 3.944, p = 0.047, OR = 1.002) was significantly associated with live births. CONCLUSIONS: Amount of PA alone did not have a positive effect on outcome of ART. Type and intensity seemed to be more significant. Existing differences in response to infertility due to recreational PA suggest the importance of the development of a specific intervention. The robust overestimation of PA in self-reports highlights the need to improve physical literacy of women undergoing ART.

Criterion validity and reliability of the International Physical Activity Questionnaire - Hungarian short form against the RM42 accelerometer.

BACKGROUND: Physical inactivity is a global phenomenon in European welfare countries. Proper monitoring is essential to measure the physical activity level of the population. METHODS: In the Hungarian cohort of the European Physical Activity and Sport Monitoring System (EUPASMOS) project, our participants (N = 598) completed sociodemographic questions and the International Physical Activity Questionnaire - short form (IPAQ-SF) survey. The validity and reliability of the subjective measurement tool were examined, IPAQ-SF outcomes were contrasted against triaxial RM42 accelerometer wore for 7 consecutive days. RESULTS: The IPAQ-SF showed moderate internal consistency (Cronbach Alpha = 0.647). The concurrent validity of the IPAQ-SF to triaxial accelerometer indicated a significant weak-to-moderate correlation (R = 0.111-0.338, p = 0.042; p < 0.001). The test-retest reliability showed a significant correlation between two measurements (R = 0.788-0.981, p < 0.001). CONCLUSION: The Hungarian version of the IPAQ-SF had excellent test-retest reliability, but low-to-fair concurrent validity for moderate and vigorous physical activity, walking and sitting time, as compared to the objective criterion measure among Hungarian adults.

Assessment of health-related quality of life and patient's knowledge in chronic non-specific low back pain.

BACKGROUND: Chronic non-specific low back pain syndrome (cnsLBP) is a severe health problem in developed countries, which has an important effect on patients' quality of life and is highly determined by socio-demographic factors and low back pain specific knowledge. We examined patients' health-related quality of life according to the results of the Short Form Health Survey (SF-36), low back pain knowledge (LBPKQ) and the social determinants of the participants. METHODS: We carried out our research in the first half of 2015 in Southern Transdanubia, Hungary. The examination included 1155 respondents living with chronic non-specific low back pain. The confidence interval of 95% was used, and the level of. significance was p < 0.05 using SPSS 22.0 software. RESULTS: The SF-36 questionnaire is suitable for the examination of patients' health-related quality of life (Cronbach's Alpha> 0.76), as the LBPKQ's Cronbach's Alpha was 0.726 also, which showed good validity. Longer-term disease meant a lower health-related quality of life (p < 0.05). A greater decrease of function (Roland Morris scores (RM)) accounts for a lower HRQoL and higher knowledge level. We found significant differences in LBPKQ scores according to sociodemographic parameters. The general health status was positively correlated with LBPKQ (p = 0.024) adjusted for demographic and pain and functional status. CONCLUSION: The negative effect of the symptoms on patients' quality of life is proved, which is determined by different socio-demographic parameters furthermore by knowledge. Above all could be useful information for professionals to adopt the right interventions.

Influencing Factors of Cardiac Adaptation in Adolescent Athletes.

Endurance training-induced changes in left ventricular diastolic function and right ventricular parameters have been investigated extensively in adolescent athletes. Our aim was to examine the parameters for adolescent athletes (n=121, 15.1±1.6 years) compared to adult athletes and age-matched non-athletes. We explored the effects of influencing factors on the echocardiographic parameters. Significantly higher E/A (p<0.05) and e' values (p<0.001) were detected in adolescent athletes compared to age-matched non-athletes' and also adult athletes' parameters. Significantly lower structural and functional right ventricular parameters (p<0.05) were detected in adult athletes. In adolescent athletes significantly higher right ventricular diameters, tricuspid S wave, right ventricular end-diastolic and end-systolic area values (p<0.05) were found compared to the matching parameters of non-athletes. We found significantly higher corrected tricuspid annular plane systolic excursion values (p<0.001) in athletes compared to the non-athletes. Based on multivariate analysis lean body mass, body surface area, age and cumulative training time were proved as strong predictive factors of both left ventricular diastolic and right ventricular parameters. Supernormal left ventricular diastolic function and significantly higher right ventricular parameters are indicative of cardiac adaptation. Well-defined cut-off values should be applied to discriminate pathological conditions in the relation of the influencing factors.

Comparative analysis of the economic burdens of physical inactivity in Hungary between 2005 and 2017.

BACKGROUND: National economies are increasingly facing the challenge of having to finance the prevention and treatment of human diseases, and of having to compensate for the resulting loss of economic production. Physical inactivity is demonstrably closely related to the risk of developing certain disease group. Physical inactivity results in direct and indirect burdens that the present study intends to quantify in Hungary for the period between 2005 and 2017. METHODS: Based on the data of the Hungarian public finances, this study determines the direct and indirect costs incurred by Hungary due to illnesses, and, through the PAR method, it quantifies the financial burden of physical inactivity incurred by the Hungarian Treasury. RESULTS: The total financial burden of illnesses in Hungary showed a decreasing tendency from 2005 to 2017, even though the year 2017 saw an increase in costs compared to 2014. Similarly, while total public expenditure on illnesses associated with physical inactivity increased by 2017 when compared to 2009, the total amount attributable to medical conditions stemming from physical inactivity still showed a decrease of 2 billion HUF in the overall period. The biggest economic burden is posed by cardiovascular diseases, hypertension and type 2 diabetes. CONCLUSIONS: The increase in the economic burden associated with physical inactivity can be attributed to the combined effect of two factors: changes in total expenditure on specific disease groups (which showed an increase in the period under review) and changes in the physical activity levels of the Hungarian population (which showed an improvement over the period under review). Initiatives in Hungary aimed at encouraging an active lifestyle from childhood onwards should be continued since - beyond the initial impact that has already been felt to some extent in recent years - these initiatives will come to their full fruition in the coming decades.

Measurement of public health benefits of physical activity: validity and reliability study of the international physical activity questionnaire in Hungary.

BACKGROUND: To ensure accurate measurement of the health benefits of habitual physical activity in large sample epidemiological studies, physical activity questionnaires (PAQs) are the most feasible methods. Therefore, the purpose of this study was the validation and cultural adaptation to the Hungarian population of the International Physical Activity Questionnaire (IPAQ-HL). METHODS: A cross-sectional study among Hungarian healthy adults (age 21.375 ± 1.940 years, n = 120) was performed comparing measures of last 7 days IPAQ-HL self- administered questionnaire and obtained accelerometer (Actigraph GT3X) data for concurrent validity, reassessed by a random subsample (n = 33) to measure reliability. RESULTS: Our results indicate acceptable criterion validity for total physical activity, moderate to vigorous physical activity (R = 0.387, p < 0.001; R = 0.331 p < 0.001 respectively) and moderate physical activity (R = 0.193, p = 0.034). The ICC scores revealed moderate to good correlations (ICC = 0.744-0.942, p < 0.001). Moderate Kaiser-Meyer-Olkin measure (0.531, p < 0.001) and good reproducibility for vigorous, moderate to vigorous and moderate activities was found for IPAQ-HL in the studied population. Nevertheless, like analogous self-reports in other languages, it overestimates the time spent on physical activity. CONCLUSIONS: IPAQ-HL proved to be a reasonably valid measure for population prevalence epidemiological studies and is suggested for use to develop public health policy recommendations or to optimize public health interventions. However, the results on vigorous activity should be interpreted with caution, the questionnaire showed moderate validity for this particular intensity.

Association with subjective measured physical activity (GPAQ) and quality of life (WHOQoL-BREF) of ageing adults in Hungary, a cross-sectional study.

BACKGROUND: It is well known that physical activity (PA) has health benefits. This study aimed to examine physical activity carried out by the senior (over 50) participants and its relation to their quality of life (QoL). METHODS: Surveillance of PA and QoL was measured by using questionnaires (GPAQ, WHOQoL-BREF) in this study. Descriptive data were presented as means and standard deviations (SD) for continuous variables and as percentages for categorical variables. Multivariate linear regression analysis was conducted. The significance level was set at p ≤ 0.05. RESULTS: Overall, 250 participants were recruited, the mean age of the study population (n = 243) was 70.2 (SD 7.1) years. The results clearly showed that the Hungarian participants aged over 50 years were more likely to do PA if they had university degree and lower age (p ≤ 0.001) and used more active transportation (p = 0.035) if they had low education. The results of WHOQoL-BREF showed that the Hungarian individuals have better QoL if they have university degree (p ≤ 0.001) and lower age (p ≤ 0.001). Using multivariate linear regression analysis to examine the effect of PA patterns on QoL adjusted for demographic variables (age, education, BMI, place of living), the result showed significant correlation between WHOQoL-BREF dimensions and GPAQ (p ≤ 0.001). CONCLUSION: Higher amount of PA among aging population can result in better QoL in all dimensions.

Cross-cultural adaptation and validation of the Global Physical Activity Questionnaire among healthy Hungarian adults.

BACKGROUND: Physical activity (PA) is an important factor among the determinants of health due to it's protective factor and preventive role. Self-reported measures such as questionnaires are most commonly used in public health studies, but may over- or underestimate actual patterns of PA. Therefore, accelerometers are widely used to assess concurrent validity. The aim of the present study was to adapt and validate the self-administered GPAQ - Hungarian version (GPAQ-H) against accelerometer data and IPAQ-Hungarian long version (IPAQ-HL) in Hungarian healthy young adults. METHODS: A cross-sectional comparative study was conducted to examine the last 7 days PA by GPAQ-H, comparing with IPAQ-HL and Actigraph GT3X accelerometer to measure concurrent validity and reliability. A convenient sample of 300 young adults was recruited in January - July 2018 at the University of Pécs, in South-Hungary, 120 participants (age 21.53 ± 1.75 years, 46.66% male) were included in the validity and reliability study. RESULTS: Significant differences between the three instruments were found (p < 0.001) in all scores, except PAQs vigorous activities (p = 0.332) and GPAQ-H and accelerometer MVPA score (p = 0.424). A moderate KMO measure was found (0.538) with a significant Barlett's test of Sphericity (279.51; p < 0.001). The total variance was explained as 81.10%. The reliability of the GPAQ-H instrument with all domain's scores was 0.521 (CI 0.371-0.644). We found in all intensity scores and sitting time good reliability scores (R = 0.899-987, p < 0.001) between the baseline and follow-up (N = 33 random subsample). The Bland-Altman plots were showed that GPAQ-H overestimates vigorous activities by 212.75 min/week (331.82-757.42) and MVPA by 104.93 min/week (- 1016.98-807.11). A high difference, 6336.79 min/week (CI 3638.18-9035.40) was revealed regarding sitting, as GPAQ-H largely underestimated the time spent sedentary. CONCLUSIONS: The Hungarian GPAQ self-administered form showed fair to moderate validity with correlation coefficients similar to other European studies. Based on our study's results it could be claimed that the GPAQ-H measurement tool is a valid and reliable questionnaire to measure the healthy Hungarian population's physical activity patterns. However, our results also proved that GPAQ-H alone is not a valid and reliable questionnaire to measure sitting time.

The effect of a community-based e-health program to promote the role of physical activity among healthy adults in Hungary.

BACKGROUND: Physically active lifestyle can prolong the years spent without chronic diseases and is strongly associated with good mental and physical health. The goal of the study was to examine the physical activity patterns of the healthy adults and the effectiveness of a community-based e-health program. METHODS: The study sample comprised of 633 participants. Analyses were based on the E-Harmony health program that was conducted in Hungary in 2014-2015. The longitudinal study measured the physical activity patterns of the healthy adult population, and a 12-month community-based internet and media program was evaluated for the target group to improve the physical activity level and related knowledge. We examined the effectiveness of the program by the International Physical Activity Questionnaire - Hungarian validated long version adjusting for socio-demographic parameters, also across multivariate linear regression analysis using SPSS 24.0 software. Confidence interval of 95% was used and the level of significance was p < 0.05. RESULTS: The total physical activity of the study sample was 5129.9 (SD = 4488.1) MET min/week. Male participants scored higher in total activity but the results showed no statistical significance. Our participants were sitting 2211.6 (SD = 1592.8) min /week on average (daily average was 315.9 (SD = 227.6) minutes); the results showed no statistically significant difference by gender. We found weak but significant relationship between the active lifestyle and anthropometric data, especially according to leisure time activities and sedentary behaviour (p < 0.001). Based on the multivariate linear regression models the socio-demographic parameters significantly affected the physical activity level of participants. After the 12-month community-based e-health program, 10.34% changes occurred in the total physical activity level (p < 0.001). CONCLUSIONS: To our knowledge, ours was the first community-based e-health program in Hungary to improve the physical activity level of the healthy adult population. Based on our results this web-based e-health program can be an adequate tool to promote healthy lifestyle. The study could provide appropriate information for the further health interventions and policy making. Further research is necessary to determine the special risk groups and to develop an applicable e-health program for such specific subgroups.

Associations between fitness levels and self-perceived health-related quality of life in community - dwelling for a group of older females.

BACKGROUND: For older adults perceived quality of life has been linked to the ability to accomplish everyday tasks, a functional capacity which is thought to be based upon physical fitness. Although there is a relationship between physical activity and quality of life in older adults, the fitness of older adults and its relationship to quality of life needs more investigation. Therefore, the purpose of this study was to examine the associations between self-reported health-related quality of life and physical fitness in community-dwelling older females. METHODS: A cross-sectional study between four different age groups in retirement villages from two different places of the southern and western region of Hungary, among 173 women between the ages of 58 and 94 years old. We measured physical fitness using the Fullerton Test protocol and self-perceived health quality of life using the Short-Form Health Survey. RESULTS: Group means were different in six-minute walk distance, handgrip strength, and arm curls. The youngest group of females had higher scores of fitness in these categories as compared to the oldest grouping of women. Quality of Life were also difference across age groupings although not linear across the four age categories. Moderate level positive relationship was evident between perceived physical function and certain categories of physical fitness. CONCLUSIONS: Sociability and self-motivation has a leading role in quality of life in elder population. It is worth putting a lot more emphasis into continuous cultural, social and most importantly into physical activity programs for elderly.

Assessing fear of childbirth and its predictors among Hungarian pregnant women using Wijma Delivery Expectancy/Experience Questionnaire subscales.

This study aimed to assess fear of childbirth (FOB) among Hungarian pregnant women and determine predictors based on WDEQ-A subscales. This cross-sectional study was conducted among 423 healthy pregnant women during their third trimester. A socio-demographic and obstetrics characteristics, the Hungarian version of WDEQ-A, Beck Depression Inventory-Short Form and Beck Anxiety Inventory were used. The analysis was performed using multivariate linear regression. Among four WDEQ-A subscales, Fear (19%) and Lack of positive emotion (13%) obtained the largest and smallest percentages of cases with severe FOB. The nulliparous obtained significantly higher mean score in subscales Isolation and Lack of positive emotion compared to the multiparous. Anxiety was the most common predictor for all subscales in both groups. In the nulliparous group, significant predictors included economic hardship for Moment of birth, being a housewife for Fear, and wanted pregnancy for Lack of positive emotion. In the multiparous women, the strongest significant predictors were being married, previous elective caesarean section and being a housewife for subscales Isolation, Moment of birth, and Fear, respectively. Assessing FOB using WDEQ-A among Hungarian women revealed different mean scores and predisposing factors for each subscale. The topic should be further explored relative to its constituent factors.

Back School programme for nurses has reduced low back pain levels: A randomised controlled trial.

AIMS AND OBJECTIVES: (i) To examine patient lifting techniques used by nurses, and (ii) to evaluate an effectiveness of the Spine Care for Nurses programme in chronic nonspecific low back pain syndrome reduction and the execution of proper patient lifting techniques. BACKGROUND: Millions of nurses around the world suffer from occupational-related chronic nonspecific low back pain (chronic nonspecific low back pain syndrome). Generally, low back pain in nurses is a result of increased pressure on the spine and can be associated with improperly conducted patient lifting techniques. METHODS: A randomised controlled trial was conducted among 137 nurses with chronic nonspecific low back pain syndrome. Participants were randomised into an experimental and control group (experimental group n = 67, control group n = 70). Nurses in the experimental group attended the Spine Care for Nurses programme for 3 months. The programme consisted of didactic education, spine-strengthening exercises and education on safe patient handling techniques. The control group only received a brief written lifestyle guidance. The Zebris WinSpine Triple Lumbar examination was used to analyse nurses' patient lifting techniques (horizontal and vertical lifting). The lumbar pain intensity was measured with a 0-100 visual analogue scale. RESULTS: The pre-intervention average chronic nonspecific low back pain syndrome intensity score on visual analogue scale decreased from 49.3 to the postintervention score of 7.5. The correct execution of vertical lifting techniques in the experimental group increased from 8.91%-97.01% (control group: 8.57% pre-intervention test and postintervention test 11.42%). The horizontal patient lifting technique pre-intervention increased from 10.44%-100% correct execution in the experimental group (control group: pre-intervention test 10.00% and postintervention test 11.42%). CONCLUSION: The Spine Care for Nurses programme significantly reduced chronic nonspecific low back pain syndrome and increased the number of properly executed horizontal and vertical patient lifting techniques in nurses. RELEVANCE TO CLINICAL PRACTICE: We recommend that healthcare organisations should consider the implementation of regular Spine Care for Nurses programmes as successful low back injury prevention programmes.

[Analysis of telemetry, on-line and non-telemetry data for characterization of the physical activity of patients with heart failure]. / Telemetriás és online nontelemetriás adatok elemzése szívelégtelen betegek fizikai aktivitásának jellemzésére.

INTRODUCTION: Several studies have demonstrated that the prevalence of heart disease can be accounted for between 0.4 and 2% in developed countries. AIM: The present study aimed to use the PA% of the telemetry data to estimate the 6-minute walk test result. METHOD: A total of seventeen patients with heart disease; 3 females and 14 males; age: 57.35 yrs ± 9.54; body mass 98.71 ± 9.89 kg; average BMI 36.69 ± 3.67 were recruited into the study. Using the two sets of values describing physical performance, linear regression was calculated providing a mathematical equation, thus, the Physical Activity % value is used to estimate the distance traveled over a 6-minute walk test. RESULTS: On further data analysis, we have come to the conclusion that the distance walked during the six-minute-long test may be measured by PA% from the data of CRT device. CONCLUSIONS: With our method, based on the values received from the physical activity sensor implanted into the resynchronisation devices, changes in patients' health status could be monitored telemetrically with the assistance from the implanted electronic device.

[Prevalence, potential risk factors and sequelae of diastasis recti abdominis]. / A rectus diastasis prevalenciája, lehetséges rizikófaktorai és szövodményei.

INTRODUCTION: There is scant knowledge on diastasis recti which occurs mostly in 3rd trimester of pregnancy. AIM: Our aim was to assign the prevalence of diastasis recti and the possible risk factors and to investigate its association with some chronical diseases, like low back pain and urinary incontinence. METHOD: 200 women's interrectus distance was measured who filled out a self-made diastasis recti questionnaire, the SF-36, Oswestry Disability Index and the International Consultation on Incontinence Modular Questionnaire - Urinary Incontinence Short Form questionnaires. RESULTS: Prevalence of the condition was 46.5%. In case of risk factors, relationship between number of deliveries and interrectus distance was significant. We found a significant difference in quality of life, in presence of low back pain and urinary incontinence between the normal and the abnormal group. CONCLUSIONS: In line with the literature we found, that diastasis recti can predispose on serious sequelae, hence on decreased quality of life. Orv. Hetil., 2017, 158(12), 454-460.
