Pooled Minimal Clinically Important Differences of the Mini-Balance Evaluation Systems Test in Patients with Early Subacute Stroke: A Multicenter Prospective Observational Study.

OBJECTIVE: Balance problems are common in patients with stroke, and the Mini-Balance Evaluation Systems Test (Mini-BESTest) is a reliable and valid assessment tool for measuring balance function. Determining the minimal clinically important difference (MCID) is crucial for assessing treatment effectiveness. This study aimed to determine the MCID of the Mini-BESTest in patients with early subacute stroke. METHODS: In this prospective multicenter study, 53 patients with early subacute stroke undergoing rehabilitation in inpatient units were included. The mean age of the patients was 72.6 (SD = 12.2) years. The Mini-BESTest, which consists of 14 items assessing various aspects of balance function, including anticipatory postural adjustments, postural responses, sensory orientation, and dynamic gait, was used as the assessment tool. The global rating of change (GRC) scales completed by the participants and physical therapists were used as external anchors to calculate the MCID. The GRC scale measured subjective improvement in balance function, ranging from -3 (very significantly worse) to +3 (very significantly better), with a GRC score of ≥ + 2 considered as meaningful improvement. Four methods were used to calculate the MCID: mean of participants with GRC of 2, receiver operating characteristic-based method, predictive modeling method, and adjustment of the predictive modeling method based on the rate of improvement. From the MCID values obtained using these methods, a single pooled MCID value was calculated. RESULTS: The MCID values for the Mini-BESTest obtained through the 4 methods ranged from 3.2 to 4.5 points when using the physical therapist's GRC score as the anchor but could not be calculated using the participant's GRC score. The pooled MCID value for the Mini-BESTest was 3.8 (95% CI = 2.9-5.0). CONCLUSIONS: The Mini-BESTest MCID obtained in this study is valuable for identifying improvements in balance function among patients with early subacute stroke. IMPACT: Determination of the MCID is valuable for evaluating treatment effectiveness. The study findings provide clinicians with practical values that can assist in interpreting Mini-BESTest results and assessing treatment effectiveness.

Clinical prediction rules for multi surfaces walking independence using the Berg Balance Scale or Mini-Balance Evaluation Systems Test in persons with stroke.

BACKGROUND: A Clinical prediction rule (CPR) for determining multi surfaces walking independence in persons with stroke has not been established. OBJECTIVES: To develop a CPR for determining multi surfaces walking independence in persons with stroke. METHODS: This was a multicenter retrospective analysis of 419 persons with stroke. We developed a Berg Balance Scale (BBS)-model CPR combining the BBS, comfortable walking speed (CWS) and cognitive impairment, and a Mini-Balance Evaluation Systems Test (Mini-BESTest)-model CPR combining the Mini-BESTest, CWS, and cognitive impairment. A logistic regression analysis was conducted with multi surfaces walking independence as the dependent variable and each factor as an independent variable. The identified factors were scored (0, 1) based on reported cutoff values. The CPR's accuracy was verified by the area under the curve (AUC). We used a bootstrap method internal validation and calculated the CPR's posttest probability. RESULTS: The logistic regression analysis showed that the BBS, CWS, and cognitive impairment were factors in the BBS model, and the Mini-BESTest was a factor in the Mini-BESTest model. The CPRs were 0-3 points for the BBS model and 0-1 points for the Mini-BESTest model. The AUCs (bootstrap mean AUC) of the CPR score were 0.89 (0.90) for the BBS model and 0.72 (0.72) for the Mini-BESTest model. The negative predictive value (negative likelihood ratio) was 97% (0.054) for CPR scores < 2 for the BBS model and 94% (0.060) for CPR scores < 1 for the Mini-BESTest model. CONCLUSIONS: The CPR developed herein is useful for determining multi surfaces walking independence.

Advanced gut-on-chips for assessing carotenoid absorption, metabolism, and transport.

Bioengineered strategies enable gut chips to faithfully replicate essential features of intestinal microsystems, encompassing geometric properties, peristalsis, intraluminal fluid flow, oxygen gradients, and the microbiome. This emerging technique serves as a powerful tool for nutrition studies by emulating the absorption and distribution processes in a manner highly relevant to human physiology. It offers unprecedented accessibility for investigating the mechanisms governing nutrition metabolism. While the application of gut-on-chip models in disease modeling and drug screening has been extensively explored, their potential in dietary nutrition research remains relatively unexplored. This comprehensive review provides an overview of the different approaches employed in constructing gut-on-chip platforms using diverse cell sources and niche mimics. Furthermore, it explores the applications and prospects of gut-on-chips in nutrition-related investigations, with a specific focus on carotenoid transport, absorption, and metabolism. Lastly, this review discusses the future development trajectory of this groundbreaking technology paradigm, highlighting its broad applicability in the field of food technology. By harnessing the capabilities of these state-of-the-art techniques within gut chip platforms, researchers can establish a robust scientific foundation for unraveling the intricate mechanisms that govern the behavior and functional properties of carotenoids.

Reliability, Validity, and Identification Ability of a Commercialized Waist-Attached Inertial Measurement Unit (IMU) Sensor-Based System in Fall Risk Assessment of Older People.

Falls are a prevalent cause of injury among older people. While some wearable inertial measurement unit (IMU) sensor-based systems have been widely investigated for fall risk assessment, their reliability, validity, and identification ability in community-dwelling older people remain unclear. Therefore, this study evaluated the performance of a commercially available IMU sensor-based fall risk assessment system among 20 community-dwelling older recurrent fallers (with a history of ≥2 falls in the past 12 months) and 20 community-dwelling older non-fallers (no history of falls in the past 12 months), together with applying the clinical scale of the Mini-Balance Evaluation Systems Test (Mini-BESTest). The results show that the IMU sensor-based system exhibited a significant moderate to excellent test-retest reliability (ICC = 0.838, p < 0.001), an acceptable level of internal consistency reliability (Spearman's rho = 0.471, p = 0.002), an acceptable convergent validity (Cronbach's α = 0.712), and an area under the curve (AUC) value of 0.590 for the IMU sensor-based receiver-operating characteristic (ROC) curve. The findings suggest that while the evaluated IMU sensor-based system exhibited good reliability and acceptable validity, it might not be able to fully identify the recurrent fallers and non-fallers in a community-dwelling older population. Further system optimization is still needed.

Assessing balance in people with bilateral vestibulopathy using the Mini-Balance Evaluation Systems Test (Mini-BESTest): feasibility and comparison with healthy control data.

OBJECTIVES: Bilateral vestibulopathy (BVP) leads to unsteadiness when walking, which worsens in darkness or on uneven ground, as well as falls. Since simple balance tests struggle to distinguish between BVP and healthy participants, we aimed (1) to test if the Mini-BESTest is feasible in BVP, (2) how people with BVP perform on the Mini-BESTest and (3) to compare these scores with healthy reference data. METHODS: Fifty participants with BVP completed the Mini-BESTest. 12-month falls incidence was obtained by questionnaire. To compare the overall and sub-scores between our participants with BVP and those of healthy participants from the literature (n = 327; obtained via PubMed searches), Mann-Whitney U tests were used. Sub scores within the BVP group were also compared. Spearman correlations were used to investigate the relationships between Mini-BESTest score and age. RESULTS: No floor or ceiling effects were observed. Participants with BVP had significantly lower Mini-BESTest total scores than the healthy group. Anticipatory, reactive postural control and sensory orientation sub scores of the Mini-BESTest were significantly lower in BVP, while dynamic gait sub scores were not significantly different. A stronger negative correlation between age and Mini-BESTest total score was found in BVP than in the healthy group. Scores did not differ between patients with different falls history. CONCLUSION: The Mini-BESTest is feasible in BVP. Our results confirm the commonly reported balance deficits in BVP. The stronger negative association between age and balance in BVP might reflect the age-related decline in the remaining sensory systems with which people with BVP compensate.

[Balance Evaluation Systems Test: German translation, cultural adaptation and preliminary results on psychometric properties]. / Balance Evaluation Systems Test: deutsche Übersetzung, kulturelle Anpassung und erste Ergebnisse zu Gütekriterien.

BACKGROUND: The Balance Evaluation Systems Test (BESTest) evaluates balance ability and identifies affected systems associated with balance deficits. OBJECTIVE: The primary objective was the translation and cultural adaptation of the BESTest into German. Secondary objective was the preliminary evaluation of psychometric properties of the BESTest. METHOD: In accordance with international guidelines, the BESTest was translated and adapted by a 7-step process. To test the psychometric properties, persons with subjective or objective balance deficits were included. Internal consistency was evaluated by means of Cronbach's alpha. The criterion validity was tested by measuring the correlation with the Berg Balance Scale (BBS). Construct validity was examined using the Activities-Specific Balance Confidence (ABC-D) scale and the known groups methods (fallers versus non-fallers). RESULTS: A total of 27 subjects were included in the testing of the psychometric properties. Cronbach's alpha was 0.95 for the total scale. The correlation of BESTest scores with those of the BBS revealed a Spearmen's ρ of 0.84 (p < 0.001) and 0.61 (p < 0.001) with those of the ABC­D scale. Fallers and non-fallers showed a trend towards different BESTest scores (p = 0.057). DISCUSSION: This paper provides a German translation of the BESTest authorized by the developer. Our preliminary results confirm reliability and validity.

Cutoff Point of Mini-Balance Evaluation Systems Test Scores for Elderly Estimated by Center of Pressure Measurements by Linear Regression and Decision Tree Classification.

BACKGROUND: Understanding balance ability and assessing the risk of possible falls are very important for elderly rehabilitation. The Mini-Balanced Evaluation System Test (Mini-BESTest) is an important survey for older adults to evaluate subject balance, but it is not easy to complete due to various limitations of physical activities, including occasional fear of injury. A center of pressure (CoP) signal can be extracted from a force pressure plate with a short recording time, and it is relatively achievable to ask subjects to stand on a force pressure plate in a clinical environment. The goal of this study is to estimate the cutoff score of Mini-BESTest scores from CoP data. METHODS: CoP signals from a human balance evaluation database with data from 75 people were used. Time domain, frequency domain, and nonlinear domain parameters of 60 s CoP signals were extracted to classify different cutoff point scores for both linear regression and a decision tree algorithm. Classification performances were evaluated by accuracy and area under a receiver operating characteristic curve. RESULTS: The correlation coefficient between real and estimated Mini-BESTest scores by linear regression is 0.16. Instead of linear regression, binary classification accuracy above or below a cutoff point score was developed to examine the CoP classification performance for Mini-BESTest scores. The decision tree algorithm is superior to regression analysis among scores from 16 to 20. The highest area under the curve is 0.76 at a cutoff point score of 21 for the CoP measurement condition of eyes opened on the foam, and the corresponding classification accuracy is 76.15%. CONCLUSIONS: CoP measurement is a potential tool to estimate corresponding balance and fall survey scores for elderly rehabilitation and is useful for clinical users.

Pavement Distress Estimation via Signal on Graph Processing.

A comprehensive representation of the road pavement state of health is of great interest. In recent years, automated data collection and processing technology has been used for pavement inspection. In this paper, a new signal on graph (SoG) model of road pavement distresses is presented with the aim of improving automatic pavement distress detection systems. A novel nonlinear Bayesian estimator in recovering distress metrics is also derived. The performance of the methodology was evaluated on a large dataset of pavement distress values collected in field tests conducted in Kazakhstan. The application of the proposed methodology is effective in recovering acquisition errors, improving road failure detection. Moreover, the output of the Bayesian estimator can be used to identify sections where the measurement acquired by the 3D laser technology is unreliable. Therefore, the presented model could be used to schedule road section maintenance in a better way.

Occupational health and safety of multinational construction companies through evaluation of corporate social responsibility reports.

INTRODUCTION: The aim of this paper is to examine Occupational Health and Safety (OHS) behavior in the construction industry through the assessment of Corporate Social Responsibility reports. The level of accident rates in the construction industry place OHS issues at the heart of their strategic management. METHOD: The assessment of OHS issues was made by drawing appropriate data from the Corporate Social Responsibility reports of 19 multinational construction companies published on a voluntary basis. RESULTS: The findings show a low response rate by the companies sampled to the requirements of stakeholders for responsible organizational behavior and accountability for their consequences. Most of the companies sampled have only focused on a small number of OHS issues to assure the transparency of the information published such as OHS governance, accident and illness rates, training hours, third party assurance, and membership of externally developed OHS charters. Similarly, other important OHS issues seem to be less covered by the companies sampled such as the representation of total workforce in OHS committees, the percentage of high risk occupations, and OHS practices in the supply chain.

Rasch Validation and Comparison of the Mini-BESTest and S-BESTest in Individuals With Stroke.

OBJECTIVE: The purpose of this study was to compare the psychometric properties of the Mini-Balance Evaluation Systems Test (Mini-BESTest) and S-BESTest and to evaluate which is more suitable for use in clinical settings for individuals with stroke. METHODS: This multicenter retrospective cross-sectional study investigated 115 individuals with stroke (mean age, 70.8 y [SD = 11.2 y]) who were able to stand without physical assistance. All individuals were examined with the BESTest and with the Mini-BESTest and S-BESTest scored based on the BESTest results. The data were analyzed using a Rasch analysis (partial credit model). RESULTS: The Mini-BESTest results revealed a correctly functioning rating scale, good fit of the data to the model (apart from 1 overfit item), good reliability for both persons and items (6 statistically detectable levels of balance ability), local dependence between 1 item pair, and essential unidimensionality. The S-BESTest results demonstrated disordered rating scale thresholds (1 response option required collapsing), good fit of the data to the model (apart from 1 underfit item), good reliability for both persons and items (5 statistically detectable levels of balance ability), local dependence between 2 item pairs, and essential unidimensionality. CONCLUSION: The analyses confirmed that the reliability of the S-BESTest was good and unidimensional and that the test provides several improved points, such as item redundancy and local independence of items. Nevertheless, the Mini-BESTest results supported previous findings as a whole and were better than those from the S-BESTest. IMPACT: Rasch analysis demonstrated that the Mini-BESTest was a better balance assessment scale than the S-BESTest for individuals with stroke based on its psychometric properties. The Mini-BESTest may serve as a useful scale for assessing balance in individuals with stroke, and a keyform plot and strata may help clinical decision-making in terms of interpreting scores and goal setting.

Citrus flavonoids and their antioxidant evaluation.

The antioxidant ability is the link and bridge connecting a variety of biological activities. Citrus flavonoids play an essential role in regulating oxidative stress and are an important source of daily intake of antioxidant supplements. Many studies have shown that citrus flavonoids promote health through antioxidation. In this review, the biosynthesis, composition and distribution of citrus flavonoids were concluded. The detection methods of antioxidant capacity of citrus flavonoids were divided into four categories: chemical, cellular, animal and clinical antioxidant capacity evaluation systems. The modeling methods, applicable scenarios, and their relative merits were compared based on these four systems. The antioxidant functions of citrus flavonoids under different evaluation systems were also discussed, especially the regulation of the Nrf2-antioxidases pathway. Some shortcomings in the current research were pointed out, and some suggestions for progress were put forward.

Relationship between Dynamic Trunk Balance and the Balance Evaluation Systems Test in Elderly Women.

OBJECTIVE: Falls are major contributors to elderly subjects becoming bedridden. Consequently, it is important to evaluate and minimize the risk of falls in the elderly. Trunk stability is important for balance function and is related to fall prevention in elderly women. We developed a balance-measuring device that uses a dynamic sitting position to safely measure balance function. The Balance Evaluation Systems Test (BESTest) is useful method to assess balance function, a recently developed balance evaluation test that can detect minor balance problems not captured by previous tests. The purpose of the present study was to examine the relationship between dynamic trunk balance and findings of the BESTest in elderly women. METHODS: Thirty-one healthy women aged 60 years or more participated in this study. The evaluation items were the BESTest total score, scores for each of the six elements of the BESTest, dynamic sitting balance, static postural balance, and muscle strength. RESULTS: The mean total BESTest score was 85.4 points. The mean total trajectory length of the center of gravity (COG) during the dynamic sitting balance test was 1447.5 mm. A negative correlation (r=-0.481, P= 0.006) was observed between the total COG trajectory length and the BESTest score. A negative correlation was also found between the total COG trajectory length and biomechanical constraints (r=-0.492, P=0.005) and anticipatory postural adjustments (r=-0.532, P=0.002). There were no correlations between the dynamic sitting balance total COG trajectory length and the stationary standing COG trajectory length or muscle strength. CONCLUSIONS: In elderly women, the total COG trajectory length during dynamic sitting was negatively correlated with the BESTest total score.

A Pilot Study of the Feasibility and Effects of Table Tennis Training in Parkinson Disease.

OBJECTIVE: To investigate feasibility and effects of table tennis training on balance control and physical function in individuals with Parkinson disease. DESIGN: Single group, observational, before-after trial. SETTING: Table tennis training in a gymnasium. PARTICIPANTS: Community-dwelling individuals with Parkinson disease (N=9; 5 men, 4 women) with an average age of 66.9 years, average time since diagnosis of 8.6 years, and a modified Hoehn and Yahr score between 2 and 2.5 participated in this study. Participants were recruited via newspaper advertisement, at the patient organization, and at the university hospital outpatient clinic. Eight participants completed the study. One participant withdrew for logistical reasons. INTERVENTIONS: Group training program consisting of 2 table tennis training sessions per week (120min each) for 10 weeks. MAIN OUTCOME MEASURES: The primary outcome was feasibility, including attendance rate, drop-out rate, a final questionnaire assessing the participants' experience during the intervention, and any adverse events. The primary effect outcome was the Mini Balance Evaluation Systems Test (Mini-BESTest). Secondary effect outcomes were Parkinson's disease questionnaire-8, European quality of life questionnaire, Montgomery Åsberg Depression Rating Scale (MADRS), Unified Parkinson's Disease Rating Scale, 10-meter walk test, generic walking scale, activities-specific balance confidence scale, and physical activity measured with an accelerometer and the Frändin-Grimby scale. RESULTS: The average attendance rate was 84%. There were no adverse events reported. The participants reported that the training improved well-being. The mean total score on the Mini-BESTest before and after intervention was 21.2 versus 23.3 (P=.093). Statistically significant positive effects without adjustment for multiple comparisons were found for MADRS and the Frändin-Grimby scale. CONCLUSIONS: This study demonstrates that table tennis training is safe and feasible, and may have the potential to improve balance control, mental well-being, and self-reported physical activity level. Further studies are required before table tennis can be considered an evidence-based recommendation for individuals with Parkinson disease.

Testing the Validity of the Diamond Steps Test for Balance in Healthy Adults.

OBJECTIVES: To test the validity of the Diamond Steps Test (DST), a new test to assess balance. DESIGN: This cross-sectional study evaluated the validity of the DST, a brief new balance assessment tool. SETTING: The implementation site was the rehabilitation center of a hospital. Data collection was conducted from February to June 2017. PARTICIPANTS: Healthy adults (N=65) between the ages of 40 and 72 years who volunteered to participate. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Two measures were used to assess DST: the time required to step around the diamond 5 times (5-DS) and the time required to step around the diamond twice, once using the dominant foot and the other using the non-dominant foot (LRDS). RESULTS: Multiple regression analysis was performed for each of the 2 methods for measuring DST. Five variables were predictive of DST as measured by the 5-DS test: the 10-Second Open Close Stepping Test, timed Up and Go (TUG) test, Y Balance Test (YBT) posterolateral reach for the left leg, Standing on One Leg with Eyes Closed (SOLEC) test for the right leg, and sex. The coefficient of determination was 0.54. For DST measured by the LRDS, 4 variables were found to be predictive: the 30-Second Chair Stand Test, YBT posterolateral reach for the left leg, TUG, and SOLEC for the right leg. The coefficient of determination was 0.49. CONCLUSION: The DST was shown to assess 7 of the 9 components of balance (static stability, functional stability limits, underlying motor systems, anticipatory posture control, dynamic stability, reactive postural control, and sensory integration), suggesting that it is a valid test to use for balance assessment.

Comparison of three systems for predicting the digestible energy value of natural grassland and lucerne hays for horses.

The accuracy and precision of the National Research Council (NRC), Gesellschaft für Ernährungsphysiologie (GfE) and Institut National de la Recherche Agronomique (INRA) systems for predicting the digestible energy (DE) value of hays were determined from the results of 15 digestibility trials with natural grassland hays and 9 digestibility trials with lucerne hays that all met strict experimental and a tight corpus of methods. The hays were harvested in the temperate zone. They covered broad ranges of chemical composition and DE value. The INRA system was more accurate than the other two systems, with the bias between the predicted and measured DE values of natural grassland and lucerne hays averaging -0.11 and -0.04 MJ/kg DM with the INRA system, 0.34 and -0.70 MJ/kg DM with the NRC system and -0.50 and -1.69 MJ/kg DM with the GfE system (P < 0.05). However, the precision of the three systems was similar; the standard error of prediction corrected by bias was not significantly different (P > 0.05). The GfE system underestimated the DE value of hays, especially of lucerne hays. The differences between the predicted and measured DE values resulted mainly from the errors in the prediction of organic matter digestibility and energy digestibility for both natural grassland and lucerne hays. Discrimination according to botanical family (grassland v. lucerne) can help improve the prediction of the DE value of hays. The choice of appropriate predictive variables is discussed in the light of differences in chemical composition and digestibility of the various cell wall components of grassland and lucerne hays. Neutral detergent fiber (NDF) may thus be preferable to ADF in the prediction equation of the DE value of lucerne hays, whereas ADF and NDF may both be relevant for natural grassland hays.
