Test-Retest Reliability and Usefulness of aFoot-Ankle Rebound-Jump Test for Measuring Foot-Ankle Reactive Strength in Athletes.

This study investigated the test-retest reliability and usefulness of the foot-ankle rebound-jump test (FARJT) for measuring foot-ankle reactive strength metrics in athletes. Thirty-six highly trained, healthy athletes (5 female; 21.5 [3.9]y; 1.80 [0.10]m; 72.7 [10.4]kg) performed 8 repeated bilateral vertical foot-ankle rebound jumps on 2 testing days. Testing days were 1week apart, and these sessions were preceded by a familiarization session. Reactive strength metrics were calculated by dividing jump height (in meters) by contact time (in seconds) for the reactive strength index (RSI) and flight time (in seconds) by contact time (in seconds) for the reactive strength ratio (RSR). The mean of 4 jumps (excluding the first and last 2 jumps) on each testing session were considered for RSI and RSR reliability and usefulness analysis. We found a high reliability of the FARJT for RSI (intraclass correlation coefficient [ICC]> .90 and coefficient of variation [CV] = 12%) and RSR (ICC ≥ .90 and CV = 8%). Regarding their usefulness, both RSI and RSR were rated as "marginal" in detecting the smallest worthwhile change (typical error > smallest worthwhile change) and "good" in detecting a moderate change in performance. The results showed that a FARJT is a highly reliable test for measuring foot-ankle reactive strength in athletes and useful for quantifying changes, for example, following a training block. However, its usefulness as an accurate daily or weekly monitoring tool in practice is questionable.

Condition Monitoring System: A Flexible Hybrid Electronics Approach for Sealed Container Applications

A comparative study is presented between two advanced flexible hybrid electronics (FHE) systems designed for monitoring temperature within storage containers across various industries, including food, pharmaceuticals, agriculture, automotive, and defense. The first system, a copper-flex system (CFS), employs an 88.9 µm polyimide substrate with 35 µm thick copper traces, coated with a 12.5 µm polyimide solder mask. The second system, a printed-flex system (PFS), utilizes a 127 µm polyimide substrate with high-temperature resistance and tensile strength. Conductive silver ink was screen-printed on the PFS substrate, and electronic components including a temperature sensor were attached. Functional and reliability tests were performed to check the accuracy and durability of the temperature sensor. Further, environmental and mechanical characterizations including moisture and insulation resistance, corrosion, elongation, bending, and terminal bond strength tests were performed based on ASTM and IPC-TM650 standards. Moisture and insulation resistance test on the PFS test coupons without a coating layer indicated stable resistance of approximately 18 MΩ, while permanent color change indicated oxidation of copper on uncoated CFS test coupons. After 72 hours of corrosion test, both the CFS and PFS “meander line” test coupons covered with polyimide showed negligible change in weight and resistance, approximately 0.35%. A Young’s modulus of 7.17 GPa and 2.6 GPa was calculated from the elongation test for the CFS and PFS, respectively. Bending tests on PFS revealed negligible average resistance change (0.1%) during 180° bending cycles, while no impact was recorded on the CFS. During the terminal bond strength test, soldered wires detached from the CFS test coupons at an average force of 43 N, while it was 3.8 N on the PFS test coupons. Both systems with polyimide coating layer demonstrate robustness and reliability for diverse applications in various industries.

Establishing H Angle Hard Tissue and H Angle Soft Tissue Norms in Skeletal Class I Malay Adult Females and the Correlation between the H Angles and Visual Perception of Laypersons.

This study aimed to establish the cephalometric norms of H angle soft tissue and H angle hard tissue of Malaysian Malay adult females, and to evaluate the correlation between H angles and visual perception in skeletal Class I Malay adult females. Eighty-five lateral cephalograms of skeletal Class I (mean ANB value = 3.15 ± 0.77) Malaysian Malay female patients aged 20 to 40 years (mean age = 28.6 ± 5.86 degrees) taken from October 2017 to December 2021 were measured for H angle soft tissue and H angle hard tissue. Twenty silhouettes were then converted from cephalometric films and were rated according to facial convexity/concavity by 20 laypersons, with re-evaluation after 2 weeks for intra- and interexaminer reliabilities. The means of the H angle soft tissue and H angle hard tissue were 15.75 ± 4.16 degrees and 11.64 ± 4.71 degrees, respectively. The intraexaminer reliability test for visual perception ranged from -0.89 to 0.99 indicating poor to excellent reliability, whereas the interexaminer reliability test was 0.82 indicating good reliability. A highly statistically significant association between the H angle soft tissue and H angle hard tissue (r = 0.938; p < 0.01) was found. There was no correlation between H angles and visual perception. The cephalometric norms of H angle hard tissue and H angle soft tissue in the Malaysian Malay female population were established: 11.64 degrees (±4.71 degrees) and 15.75 degrees (±4.16 degrees), respectively. There was a strong correlation between H angle soft tissue and H angle hard tissue among skeletal Class I Malay adult females. There was no correlation between H angles and the visual perception of laypersons.

Influence of residential physical environments on occupant experience: considering the moderating effects of indoor plants and climate zones

PurposeHome is a place/system/product that becomes increasingly occupied with various tasks used to be performed in workplaces. However, the knowledge of the relationship between residential physical environments and occupant experience is limited, especially when considering the effect of indoor plants (IPs) and climate zones. To address the gap, this study conducted a questionnaire survey in three cities across different regions in China.Design/methodology/approachBased on User Experience and Customer Satisfaction Index theory, following the research paradigm, a total of 627 valid samples were collected and analyzed in a stepwise statistical analysis, including descriptive statistics, reliability and validity test, correlation test and region comparison, then the model of PROCESS was adopted to examine the hypotheses that are given based on the former studies.FindingsThe results showed that residential physical environments have a significant effect on occupant satisfaction (OS) in all regions, as well as OS on occupant performance. However, regional differences were found that OS is a complete mediator in the Middle region, while a partial mediator in the North and South. A slight moderating effect of IPs was also found in the region of South. Nevertheless, both the number of plants and plant types have a significant moderating effect on the mechanism.Originality/valueBesides combining two theories and confirming the mechanism in the residential physical environment, it is also the first study to consider the moderating effects of IPs and climate zones, providing potential empirical support for not only design and management stages but also facing global challenges of working at home and climate changes.

Assessment of Food Masticatory Capability with Clear Aligners

Nowadays, aligners represent a possible therapeutical approach that combines both esthetic and function in order to address dental malocclusion. However, they require a significant level of compliance from the patient. According to the manufacturer, at least 22 h of wearing a day is demanded to reach the optimal therapeutical level; hence, aligners can only be removed during meals. Patients’ compliance might increase and the duration of the treatment might decrease if they were allowed to eat with aligners on. The idea of patients keeping the aligners on during meals has been contemplated, not only to favor patients’ compliance but also treatment effectiveness. This study aims to assess the degree of chewing difficulty that aligners cause when eating certain kinds of food and the quantity of residue left. Material and Methods: A questionnaire titled “Questionnaire for the Assessment of Masticatory Function with Aligners” was administered using Google Forms to 240 patients in treatment with clear aligners. The survey was validated through the reliability test using the test–retest method. This method had a higher correlation coefficient of 0.9 across all items (with a cutoff of 0.8) with statistical significance, and an excellent internal correlation coefficient (α &gt; 0.9). The statistical analysis performed consisted of descriptive analysis, frequencies, percentages, Pearson’s correlation test and Friedman’s test. Results: Pearson’s test showed a statistically significant correlation between all items except between meat or clams and yogurt or ice cream and with mozzarella or soft cheese regarding food chewing difficulties. Pearson’s test showed a statistically significant correlation between all items regarding food residues. A total of 69.2% of the cohort reported some movements of aligners during mastication. In total, 88.3% of them affirmed not to have perceived deformations or breakage of aligners during chewing. Furthermore, 79.2% of them declared that they would continue to eat if eating with aligners was proven to speed up treatment. Conclusions: Wearing clear aligners while chewing foods such as yogurt, ice cream, soft cheese, bread, rice, etc., can be possible and can help shorten the duration of orthodontic treatment, benefiting both the patient and the orthodontist. However, further research using qualitative methods is needed to understand the barriers and facilitators to chewing food with aligners.

Assessment of Aminoglycoside-Induced Hearing Loss Risk in the Perinatal Period.

This study aimed to determine the prevalence and heteroplasmy level(s) of MT-RNR1 variants m.1555A > G and m.1494C > T, which are associated with aminoglycoside-induced hearing loss, in a general perinatal population. This study also aimed to characterize the association of these variants and their heteroplasmy levels with hearing loss outcomes with and without aminoglycoside exposure. Droplet digital polymerase chain reaction was performed on 479 maternal DNA samples from a general perinatal biobank at our institution to detect the presence and heteroplasmy levels of MT-RNR1 variants m.1555A > G and m.1494C > T. Testing of paired neonatal specimen(s) was planned for positive maternal tests. A retrospective chart review was performed to characterize the population, identify aminoglycoside exposures, and determine hearing outcomes. All maternal samples tested negative for MT-RNR1 variants m.1555A > G and m.1494C > T. Maternal and neonatal subjects had high rates of aminoglycoside exposure (15.9 and 13.9%, respectively). No subjects with sensorineural or mixed hearing loss had documented aminoglycoside exposure. This study demonstrated that a larger sample size is needed to establish the prevalence of these variants as no subjects tested positive. Determination of variant prevalence in the neonatal population, association of variant heteroplasmy levels with hearing outcomes, and reliability of maternal testing as a surrogate for neonatal testing are important next steps toward universal prenatal or newborn screening. · MT-RNR1 variants are associated with aminoglycoside-induced hearing loss.. · Prevalence of MT-RNR1 variants is uncertain.. · Universal screening for MT-RNR1 variants may be indicated..

Family well-being of single and dual earner families in Indonesia during COVID-19

The COVID-19 pandemic has brought life changing conditions to families that require coping strategies in order to survive and achieve family well-being. This study aims to analyze differences between single earner and dual earner families during the COVID-19 pandemic and to analyze the factors that influence subjective family well-being. The research design used was a cross sectional study with sample collection through non-probability sampling. Data collection was carried out by filling out questionnaires online. The number of respondents involved in the study was 2084 intact families with children residing in DKI Jakarta, West Java, and Banten Provinces. Reliability and validity tests were conducted. The results of the independent t-test showed that dual-earner families experienced better life changes and a higher level of subjective family well-being than single-earner families and had lower economic pressure and lower economic coping than single earner families. The SEM analysis found that life changes affected economic coping negatively and subjective family well-being positively. Family income influenced economic coping negatively and subjective family well-being positively. Finally, it was found that economic coping had no effect on subjective family well-being.

Last general practitioner consultation during the final month of life: a national medical record review of suicides in Sweden

ObjectivesIndividuals who die by suicide often consult their general practitioners (GPs) in their final weeks of life. The aim of this study was to gain a deeper knowledge of the clinical characteristics and GP assessments and treatments among individuals who consulted their GPs during the month preceding suicide. Further, we compared these features in those with and without contact with psychiatric services (PC and NPC, respectively) during the two years that preceded the suicide.DesignA nationwide retrospective explorative study investigating medical records.SettingPrimary care in Sweden.ParticipantsIndividuals who died by suicide in Sweden in 2015 with a GP visit within 30 days of death.ResultsThe study cohort corresponds to one fifth (n = 238) of all suicides that occurred in Sweden in 2015 (n = 1179), representing all those with available primary care records showing contact with a GP during the final 30 days of life (NPC: n = 125; PC: n = 113). The mean age was 58 years ± 19. Patients in the NPC group were older (NPC: 63 years ± 19 vs. PC: 53 years ± 18, p < 0.0001) and presented psychiatric symptoms less often (NPC: 50% vs. PC: 67%, p < 0.006). Somatic symptoms were as common as psychiatric symptoms for the whole sample, being present in more than half of individuals. Suicide risk was noted in only 6% of all individuals. Referral to psychiatric services occurred in 14%, less commonly for the NPC group (NPC: 6% vs. PC: 22%, p < 0.001). Cardiovascular or respiratory symptoms were noted in 19%, more often in the NPC group (NPC: 30% vs. PC: 6%, p < 0.001), as were diagnoses involving the circulatory system (all 10%, NPC:14% vs. PC: 5%, p < 0.020).ConclusionA high level of somatic symptoms was observed in primary care patients both with and without psychiatric contact, and this might have influenced GPs’ management decisions. Psychiatric symptoms were noted in two thirds of those with psychiatric contact but only half of those without. While GPs noted psychiatric symptoms in over half of all individuals included in the study, they seldom noted suicide risk. These findings highlight the need for increased attention to psychiatric symptoms and suicide risk assessment, particularly among middle-aged and older individuals presenting with somatic symptoms.Strengths and limitations of this studyThe National Cause of Death Register has excellent coverage of suicide deaths and access to medical records was very good. The medical record review provided detailed information regarding primary care utilization before death by suicide. Because of the lack of statistical power, due to the limited number of persons with GP contact during the last month of life, we chose not to correct for multiple comparisons. Our study approach did not capture the reasons behind GPs’ documentation of elevated suicide risk. No systematic inter-rater reliability (IRR) testing was made, however, reviewers received training and continuous support from the research group.

Assessment of the Factors Affecting the National ICT Broadband Backbone (NICTBB) Systems Restoration Time

This study investigates the factors affecting the prolonged system restoration time when national ICT broadband backbone (NICTBB) services are affected by breakdown incidents. NICTBB is the government-owned backbone infrastructure constructed nationally by the Republic of Tanzania to increase the usage of ICT for equitable and sustainable socio-economic development and accelerate poverty reduction. This study utilised a mixture of exploratory and descriptive study approaches. The sample size determination was executed using purposing and simple random sampling, thus involving 289 respondents. The data reliability test was undertaken. It was followed by factor analysis, analysis of variances (ANOVA), linear regression analysis, and confirmed with confirmatory factor analysis (CFA) using IBM SPSS Amos 28 to test the model fitness. The study revealed that the maintenance centres are few and sparsely located, and the distance from maintenance centres increases travelling time, resulting in increased time to restore services. Some factors affecting the restoration time include initial infrastructure design not trenching to locate points of cut, absence of dedicated vehicles standby for NICTBB restoration, retirements of experienced and well-trained staff leaving behind untrained personnel for maintenance activities, and insufficient funds for maintenance. Lastly, power equipment is not looked upon as sometimes the services are down due to commercial power cuts, tripped circuit breakers, and batteries not being charged. Some recommendations include having proper maintenance processes, having enough restoration resources at all maintenance centres, and maintaining proper communication.

The Spanish Adaptation of the Tampa Scale for Kinesiophobia Heart: Psychometric Evidence in Cardiac Rehabilitation Patients.

The factor structure of the Tampa Scale of Kinesiophobia Heart version has rarely been adequately analyzed. We aimed to evaluate the psychometric properties of this scale through a variety of exploratory and confirmatory factorial approaches. To perform a translation, cross-cultural adaptation, and psychometric evaluation of the Spanish version of the Tampa Scale of Kinesiophobia Heart in patients attending Cardiac Rehabilitation (TSK-SPA). Cross-sectional study. A Cardiac Rehabilitation unit. Adults with the principal diagnosis of coronary artery disease (83%) who were referred to Cardiac Rehabilitation (N.=194; mean age, 64.28±9.2; 15% women). We performed a translation and a cross-cultural adaptation of the TSK-SPA. The psychometric properties of validity comprising the face, content, and construct validity were then tested. Five factorial models were proposed to analyze the data structure. We examined the validity evidence of the TSK-SPA based on the relationships with other analyzed variables using the SF12 quality of life Questionnaire, the International Physical Activity Questionnaire, the Hospital Anxiety and Depression Scale and the Beck Depression Inventory. The reliability tests included internal consistency and stability over time. The results suggested a four-dimensional structure. Models with more than 1 dimension exhibited undesirable factor loadings or inadequate fit indices. Based on these results, a short version of the scale with 13 items is proposed. In terms of reliability, the TSK-SPA Heart was found internally consistent (α=0.79) and stable over time (test-retest = 0.82). An Exploratory Structural Equation Modeling (ESEM) analysis provided an acceptable fit for a hypothesized 4-factor model with the inclusion of a method factor: the root mean squared error of approximation was <0.05 (RMSEA = 0.046), and the comparative fit indices were >0.95 or close (CFI=0.994, TLI=0.934). Significant positive correlations were observed between the TSK-SPA scores and the measures of anxiety and depression, with correlation coefficients ranging from 0.35 to 0.48. A best-fitting model was identified, and the proposed 13-item TSK-SPA Heart showed sufficient evidence of validity and reliability for Spanish patients with cardiovascular disease. The scale's overall reliability is deemed acceptable, although the factor reliability could be further enhanced. Using this questionnaire on fear or avoidance of movement will improve our understanding of cognitive-behavioral factors in patients with cardiovascular disease, aiding their rehabilitation and optimizing their prognosis.

How does recall bias in farm labor impact separability tests?

In the agricultural household literature, empirical tests of separability between production and consumption decisions commonly exploit theoretical predictions of household labor allocation. Many of these studies rely on data that asks respondents to recall labor usage over the entire growing season. Two recent field experiments in Tanzania and Ghana show that such labor use data, collected at the end of the growing season, is a systematically unreliable measure of actual labor allocation. In this study, we examine how inaccurate measures of labor influence the reliability of market failure tests based on separability. In Ghana, we find no statistical evidence that recall bias influences the reliability of the separability test. In Tanzania, we find that recall bias increases the probability that such tests fail to reject separability. Thus, we find partial evidence that classic tests based on typical household survey labor data may erroneously conclude that markets are adequately functioning.

Reliability of the Test of Gross Motor Development Third Edition Among Children with Developmental Coordination Disorder

Aim The Test of Gross Motor Development Third Edition (TGMD-3) is used to assess the development of fundamental movement skills in children from 3 to 10 years old. This study aimed to evaluate the intra-rater, inter-rater, and test-retest reliability and to determine the minimal detectable change (MDC) value of the TGMD-3 in children with developmental coordination disorder (DCD). Methods The TGMD-3 was administered to 20 children with DCD. The child’s fundamental movement skills were recorded using a digital video camera. Reliability was assessed at two occasions by three raters using the generalizability theory. Results The TGMD-3 demonstrates good inter-rater reliability for the locomotor skills subscale, the ball skills subscale, and the total score (φ = 0.77 − 0.91), while the intra-rater reliability was even higher (φ = 0.94 − 0.97). Test-retest reliability was also shown to be good (φ = 0.79-0.93). The MDC95 was determined to be 10 points. Conclusion This study provides evidence that the TGMD-3 is a reliable test when used to evaluate fundamental movement skills in children with DCD and suggests that an increase of 10 points represents a significant change in the motor function of a child with DCD.

The Concurrent Validity and Reliability of a Global Positioning System for Measuring Maximum Sprinting Speed and Split Times of Linear and Curvilinear Sprint Tests

This study investigated the reliability and validity of linear sprint tests (LS) and curvilinear sprint tests (CS) using a GPS device (GPEXE lt). Twenty-one (21) student athletes completed a 40 m LS as well as a left and right CS. Maximum sprint speed (MSS) and split times at short (0–10 m), intermediate (0–20 m), and long (0–30 m) distances were determined using the GPEXE lt and single-beam timing gates (TG). Intrasession reliability and concurrent validity of GPEXE lt were assessed. The GPEXE lt consistently showed high reliability for MSS (ICC ≥ 0.95; CV ≤ 1.8%), despite underestimation compared to TG (bias = −2.57 to −0.95%; ICC ≥ 0.87). Acceptable reliability was observed for CS and LS intermediate and long distance split times (ICC ≥ 0.91; CV ≤ 2.1%), with lower reliability for short distances (ICC ≥ 0.70; CV ≤ 3.6%). The GPEXE lt split times for CS and LS showed good agreement with TG (ICC ≥ 0.66), but were overestimated at long distances (5.5–9.7%) and short distances (11.1–14.6%). Although the MSS was found to be the most reliable and valid variable to assess LS and CS speed performance with GPEXE lt, caution is needed due to limited validity.

Validity and Reliability of the Power Slap Board as an Application to Measure Upper Body Vertical Pulling Power for Female Water Polo Players.

Lim, C, Wee, J, Lee, M, Lim, S, and Leow, S. Validity and reliability of the power slap board as an application to measure upper body vertical pulling power for female water polo players. J Strength Cond Res XX(X): 000-000, 2024-This study examined the validity and reliability of the power slap test (PS) as an assessment for upper body pulling power to predict water polo functional performance and competitive experience of female water polo players. Seventeen female water polo players from the national and development squads were recruited. Subjects completed test-retest sessions of PS testing and 1 session of functional performance tests for the 15-m arms-only sprint (15 mAOS) and the 5-m maximum shooting velocity (5 mMSV). All PS, 15 mAOS and 5 mMSV results were compared for predictability. Power slap scores demonstrated high reliability for left PS (intraclass correlations [ICC]: 0.96, 90% confidence interval [CI]: 0.91-0.98), right PS (ICC: 0.96, 90% CI: 0.90-0.98), left and right center of mass (COM) displacement (ICC: 0.98, 90% CI: 0.96-0.99; ICC: 0.95, 90% CI: 0.88-0.98), and summed PS (ICC: 0.96, 90% CI: 0.92-0.99). All absolute PS scores and left COM displacement (COMdispL) demonstrated large correlations with the 15 mAOS times (r = -0.542 to -0.52, r2 = 0.27-0.29, p < 0.05). No performance parameters of the PS were correlated with the 5 mMSV performance (p > 0.05). This study validates the reliability of the PS as a dryland assessment tool for upper body pulling power. Only absolute PS scores and COMdisp were validated as weak predictors of the arms-only sprint times over 15 m. Its predictive power significantly improved when considered in combination with shooting performance. All absolute and normalized kinetic and kinematic PS parameters did not predict functional performance and competitive experience.

Accuracy of fetal fraction measurements in a single-nucleotide polymorphism-based noninvasive prenatal test.

Noninvasive prenatal testing (NIPT) for fetal aneuploidy relies on the analysis of fetoplacental cell-free DNA (cfDNA) found in maternal plasma. A minimum cfDNA fetal fraction (FF) is required for reliable test performance, but some methods may have suboptimal accuracy for FF measurement. This study investigated the accuracy of a single-nucleotide polymorphism- (SNP-) based NIPT method to assess FF. FF measurements using SNP-based NIPT in consecutive samples from singleton male pregnancies were compared with FF measured using a "gold standard" Y-chromosome method. In a cohort of 106,846 samples, the SNP-based FF method showed a standard deviation (SD) of 0.42%. Compared to the Y chromosome FF method, a correlation coefficient, r, of 0.995, and bias of 0.17% were observed. The SD was not substantially different across specific FF ranges or for samples with high-risk NIPT results. The SNP-based NIPT method estimates FF with good accuracy, with a SD three to eight times better than other NIPT methods (0.42% vs. 1.3%-3.4%). FF is an important quality control parameter and should be routinely reported as part of NIPT.
