Introduction: In the Russian Federation, much attention is traditionally paid to military education and training. A special place in its structure is occupied by the system of cadet classes and corps. A distinctive feature of the learning mode in such institutions is a combined effect of standard and specific factors of indoor school environment and intensive physical activity owing to sports, applied military and drill training. No evidence-based methods of establishing nutrient requirements of children in modern conditions of cadet corps have been developed so far, which predetermines the potential of transforming nutrition from a health-saving factor into a health risk factor. Our objective was to provide a scientific substantiation of the model of healthy nutrition for students of cadet-type educational establishments. Methods: The statistical significance of the correlation was evaluated using the Student’s t-test. Correlation and regression analyses were used to assess cause-and-effect relationships. The Pearson correlation coefficient (rxy) was used as an indicator of the strength of the relationship between quantitative indicators x and y, both having a normal distribution. Correlation coefficient (rxy) values were interpreted in accordance with the Chaddock scale. For the purpose of statistical modeling, the method of multiple linear regressions was used. Conclusions: We substantiated the innovative model of organizing healthy nutrition for students of cadet-type schools based on the correlation and regression analyses with determination of statistical significance of the studied characteristics. Its efficiency indicators include an increase in average functional capabilities of students by more than 10 % and a reduction in the probability of developmental disorders by more than 25 %.

Purpose: Purpose of this study is to evaluate the measuring consistency of central refraction between multispectral refraction topography (MRT) and autorefractometry.Methods: This was a descriptive cross-sectional study including subjects in Sun Yat-sen Memorial Hospital from September 1, 2020, to December 31, 2020, ages 20 to 35 years with a best corrected visual acuity of 20/20 or better. All patients underwent cycloplegia, and the refractive status was estimated with autorefractometer, experienced optometrist and MRT. We analyzed the central refraction of the autorefractometer and MRT. The repeatability and reproducibility of values measured using both devices were evaluated using intraclass correlation coefficients (ICCs).Results: A total of 145 subjects ages 20 to 35 (290 eyes) were enrolled. The mean central refraction of the autorefractometer was −4.69 ± 2.64 diopters (D) (range −9.50 to +4.75 D), while the mean central refraction of MRT was −4.49 ± 2.61 diopters (D) (range −8.79 to +5.02 D). Pearson correlation analysis revealed a high correlation between the two devices. The intraclass correlation coefficient (ICC) also showed high agreement. The intrarater and interrater ICC values of central refraction were more than 0.90 in both devices and conditions. At the same time, the mean central refraction of experienced optometrist was −4.74 ± 2.66 diopters (D) (range −9.50 to +4.75D). The intra-class correlation coefficient of central refraction measured by MRT and subjective refraction was 0.939.Conclusions: Results revealed that autorefractometry, experienced optometrist and MRT show high agreement in measuring central refraction. MRT could provide a potential objective method to assess peripheral refraction.

Development And Validation

The present study aimed to develop and validate an Interdisciplinary Worker’s Health Approach Instrument (IWHAI). The development stage comprised a group of 10 professionals, including physicians, nurses, nutritionists, dentists and physical educators, as well as a judges’ committee, composed by 19 recognized experts in the area of worker’s health (WH). For the validation of the IWHAI, the Spearman’s correlation coefficient (rs) was calculated, the factor analysis to the instrument was applied, and the Cronbach’s alpha (α) and the Intraclass correlation coefficient (ICC) were calculated. The IWHAI was structured in five dimensions, integrating 43 health indicators, on a scale of 0–4, totalling 215 sub-indices with closed response coding. The instrument was validated with a Kappa coefficient (KAPPA) (k), with excellent agreement for all attributes, i.e., k = 0.88 for applicability, k = 0.80 for clarity and k = 0.82 for relevance. p > 0.05 results reveal moderate to strong positive correlations between some variables, i.e., pests, vectors and air quality/drinking water quality (rs = 0.69). A total of 14 components of the factor analysis, explaining 62.6% of the data variance, were extracted. α value is considered moderate to high, α = 0.61, the ICC value also being considered moderate to high, with ICC = 0.61. The IWHAI is considered validated, constituting a technological innovation for an interdisciplinary approach in the field of WH, enabling the prevention and integral promotion of health.

The Motor Status Scale (MSS) measures shoulder, elbow (maximum score = 40), wrist, hand, and finger movements (maximum score = 42), and expands the measurement of upper extremity impairment and disability provided by the Fugl-Meyer (FM) score. This work examines the interrater reliability and criterion validity of the MSS performed in patients admitted to a rehabilitation hospital 21 ± 4 days after stroke. Using the MSS and the FM, 7 occupational therapists masked to each other’s judgments, evaluated 12 consecutive patients with stroke. Two therapists evaluated 6 additional patients on consecutive days. Intraclass correlation coefficients were significant for each group of raters for the shoulder/elbow and for the wrist/hand (P < 0.0001); test-retest measures were also significant for the shoulder/elbow (Pearson correlation coefficient r = 0.99, P < 0.004) and for the wrist/hand (Pearson correlation coefficient r = 0.99, P < 0.003). The internal item consistency for the overall MSS was significant (Cronbach alpha = 0.98, P < 0.0001). Finally the correlation between the MSS and the FM (R 2 = 0.964) was significant (P < 0.0001). The MSS affords a reliable and valid assessment of upper limb impairment and disability following stroke.

Falls represent a major public health problem in the elderly population. The Timed Up & Go test (TU & Go) is the most used tool to measure this risk of falling, which offers a unique parameter in seconds that represents the dynamic balance. However, it is not determined in which activity the subject presents greater difficulties. For this, a feature-based segmentation method using a single wireless Inertial Measurement Unit (IMU) is proposed in order to analyze data of the inertial sensors to provide a complete report on risks of falls. Twenty-five young subjects and 12 older adults were measured to validate the method proposed with an IMU in the back and with video recording. The measurement system showed similar data compared to the conventional test video recorded, with a Pearson correlation coefficient of 0.9884 and a mean error of 0.17 ± 0.13 s for young subjects, as well as a correlation coefficient of 0.9878 and a mean error of 0.2 ± 0.22 s for older adults. Our methodology allows for identifying all the TU & Go sub–tasks with a single IMU automatically providing information about variables such as: duration of sub–tasks, standing and sitting accelerations, rotation velocity of turning, number of steps during walking and turns, and the inclination degrees of the trunk during standing and sitting.

Abstract Background The Balance Evaluation Systems Test (BESTest) and its abbreviated version, the Mini-BESTest are clinical examination of balance impairment, but its psychometric properties have not yet been tested in European Spanish. We aimed to assess the psychometric properties of BESTest and Mini-BESTest in Spanish in community-dwelling elderly people. Methods We designed a cross-sectional transcultural adaptation and validation study. Convenience sample of thirty (N-30) adults aged 65 to 89 years old without balance problems were recruited. Two physiotherapists assessed participants at the same time. Internal consistency of Spanish BESTest and Mini-BESTest was carried out by obtaining the Cronbach Alpha. The reproducibility between raters was studied with the Intraclass Correlation Coefficient. The Pearson correlation coefficient was calculated by comparing the relationship between the BESTest, mini-BESTest, Berg Balance Scale (BBS) and Falls Efficacy Scale-International (FES-I). Results BESTest and Mini-BESTest showed good internal consistency. BESTest and Mini-BESTest total scores showed an excellent inter-rater agreement. There was a significant correlation between total score of the BESTest and the Mini-BESTest (r = 0.65; p < 0.001). BESTest had a moderate association with BBS and a strong association with FES-I. Mini-BESTest had a fair correlation with BBS and FES-I. Total scores obtained by women at BESTest and at Mini-BESTest were significantly lower than those reached by men. The differences observed in all the test when disaggregating data by sex require further research. Conclusions Spanish versions of BESTest and Mini-BESTest are comprehensible for new raters. They are reliable tools to provide information on which particular balance systems show impairment in community dwelling older adults. Elderly women had a worse quality of balance and a greater perception of their risk of falling. Trial registration This study was registered in ClinicalTrials.gov with NCT 03403218 on 2018/01/17.

Patient Relationship

Introduction. Nurse/patient relationship as a complex interrelation or as an interaction of the factor patient and factor nurse has been a subject of a number of studies during the past ten years. Nurse/patient communication is a special entity, usually observed within a framework of the wider nurse/ patient relationship. In that regard, we wanted to develop a standardized questionnaire that could reliably measure the quality of communication between nurse and patient, and be used by nurses. Objectives. The main goal of this study was to develop and evaluate construct validity of the Nurse Quality of Communication with Patient Questionnaire (NQCPQ), as well as to evaluate its reliability. The goal was also to establish a measure of inter-raters reliability, using two repeated measurements of results by items and scores of the NQCPQ, on the same observed units by two assessors. Methods. The starting NQCPQ that consists of 25 items, was filled in by two groups of nurses. Each nurse was questioned during morning and afternoon shifts, in order to evaluate their communication with hospitalized patients, using marks from 1 to 6. To evaluate construct validity, we used the analysis of main components, while reliability was assessed using intraclass correlation coefficient and Cronbach-alpha coefficient. To evaluate interraters reliability, we used Pearson correlation coefficient. Results. Using a group of 118 patients, we explained 86% of the unknown, regarding the investigated phenomenon (communication nurse/patient), using one component by which we separated 6 items of the questionnaire. Inter-item correlation (?) in this component was 0.96. Pearson correlation coefficient was highly significant, value 0.7 by item, and correlation coefficient for scores at repeated measurements was 0.84. Conclusion. NQCPQ is 6-item instrument with high construct validity. It can be used to measure quality of nurse/patient communication in a simple, fast and reliable way. It could contribute to more adequate research and defining of this problem, and as such could be used in studies of interaction of psychometric, clinical, biochemical, socio-cultural, demographic and other parameters as well.

BackgroundPerceived ability or confidence plays an important role in determining function and behavior. The modified Gait Efficacy Scale (mGES) is a 10-item self-report measure used to assess walking confidence under challenging everyday circumstances.ObjectiveThe purpose of this study was to determine the reliability, internal consistency, and validity of the mGES as a measure of gait in older adults.DesignThis was a cross-sectional study.MethodsParticipants were 102 community-dwelling older adults (mean [±SD] age=78.6±6.1 years) who were independent in ambulation with or without an assistive device. Participants were assessed using the mGES and measures of confidence and fear, measures of function and disability, and performance-based measures of mobility. In a subsample (n=26), the mGES was administered twice within a 1-month period to establish test-retest reliability through the intraclass correlation coefficient (ICC [2,1]). The standard error of measure (SEM) was determined from the ICC and standard deviation. The Cronbach α value was calculated to determine internal consistency. To establish the validity of the mGES, the Spearman rank order correlation coefficient was used to examine the association with measures of confidence, fear, gait, and physical function and disability.ResultsThe mGES demonstrated test-retest reliability within the 1-month period (ICC=.93, 95% confidence interval=.85, .97). The SEM of the mGES was 5.23. The mGES was internally consistent across the 10 items (Cronbach α=.94). The mGES was related to measures of confidence and fear (r=.54–.88), function and disability (Late-Life Function and Disability Instrument, r=.32–.88), and performance-based mobility (r=.38–.64).LimitationsThis study examined only community-dwelling older adults. The results, therefore, should not be generalized to other patient populations.ConclusionThe mGES is a reliable and valid measure of confidence in walking among community-dwelling older adults.

Abstract Background: In the last few decades, research related to balance in older adults has been conducted in lab-based settings. The lack of portability and high cost that is associated with the current gold standard methods to quantify body balance limits their application to community settings such as independent living facilities. The purpose of the study was to examine the relative and absolute reliability and the convergent validity of static standing balance performance using an accelerometer device . Methods: A total of 131 participants (85% female, mean age 80 ± 8 years) were included for the validity aim, and a subsample of 38 participants were enrolled in the reliability testing (89% female, mean age 76 ± 7 years). The root-mean-square (RMS) and normalized path length (NPL) for sway in antero-posterior (AP) and medio-lateral (ML) directions were calculated for different standing balance conditions. Test-retest reliability was assessed over two testing visits occurring one week apart using the intraclass correlation coefficient (ICC) for relative reliability, and the minimal detectable change (MDC) was calculated for the absolute reliability. Spearman’s rank correlation coefficient was used to test convergent validity at baseline between balance measurements and related mobility measures. Results: Reliability of balance performance using accelerometers was good to excellent with ICC values ranging from 0.41 to 0.83 for RMS sway and from 0.49 to 0.82 for NPL sway. However, the ICC during semi-tandem stance in A-P direction was 0.35, indicating poor reliability. The MDC of the sway measurements ranged from 2.4 to 9.4 for the RMS and 5.2 to 13.8 for the NPL. Balance measurements were correlated with mobility measurements. Conclusions: Using a portable accelerometer to quantify static standing postural control provides reliable measurements in community settings.
