Gait Biomechanics and Balance Associate with Talar and Subtalar T1ρ Relaxation Times in Those with Chronic Ankle Instability

ABSTRACT Purpose This study aimed to determine associations between T1ρ relaxation times of talar and subtalar articular cartilage and commonly altered gait biomechanics and postural control outcomes in those with chronic ankle instability (CAI). Methods Fifteen individuals with CAI (21.13 ± 1.81 yr) completed a T1ρ magnetic resonance imaging as well as a postural control and an overground gait assessment. Talocrural and subtalar cartilage was segmented manually to calculate T1ρ relaxation times. Greater T1ρ relaxation times were interpreted as decreased proteoglycan content. Pearson product–moment bivariate correlations examined the relationships between T1ρ relaxation times and the gait biomechanics and postural control outcomes. Results Across multiple variables, worse postural control demonstrated moderate to strong associations (range, 0.433–0.642 and −0.713) with greater talar T1ρ relaxation times. At the subtalar joint, greater T1ρ relaxation times were associated with lower peak vertical ground reaction forces, lower average vertical ground reaction force loading rates, and lower peak loading rates (range, −0.438 to −0.622). At the talar dome, greater talar T1ρ relaxation times were associated with increased knee extensor moments (r = 0.457), as well as greater knee flexion (r = 0.482) and knee adduction (r = 0.407) at initial contact. Larger step spatiotemporal gait parameters also associated with greater talar and subtalar T1ρ relaxation times (range, 0.434–0.697). Conclusions In individuals with CAI, worse postural control and altered kinematic, kinetic, and spatiotemporal outcomes demonstrate moderate to strong associations with greater talar T1ρ and/or subtalar relaxation times (i.e., less proteoglycan content). Associations between modifiable neuromechanical variables and greater T1ρ relaxation times may represent potential therapeutic interventions to mitigate ankle joint degeneration in those with CAI.
Changes in Physical Activity and the Occurrence of Specific Symptoms of “Long-COVID Syndrome” in Men Aged 18–25

The aim of this study was to assess the occurrence of non-specific symptoms of “long-COVID syndrome” depending on the physical activity undertaken resulting from the imposed forms of study (distance learning–contact learning); 136 men aged 21.5 ± 1.58 from universities educating students of medical faculties were examined. The difference between the universities was mainly due to the nature of the classes undertaken (classes remotely-hybrid form) in the period from March 2020 to February 2021. Among the respondents, 17% in Group I and 16% in Group II were infected with the SARS-CoV-2 virus, including 50% in Group I with moderate symptoms, and in Group II—most people 45% with mild symptoms. The conducted research clearly shows the impact of the COVID-19 pandemic on students. They show a number of important problems, such as reduced physical activity, as well as increased body weight and time spent in front of the monitor. They also make it clear that the health consequences of the pandemic affect both people who were infected with the SARS-CoV-2 virus and those who did not suffer from this infection.
Thirteen-level UXE-type inverter with 12-band hysteresis current control employing PSO based PI controller

This work presents hysteresis control applied to UXE-type inverter topology with a PI (Proportional Integral) controller, where thegains are derived by Particle Swarm Optimization (PSO). The investigated UXE inverter can generate a thirteen level output voltage waveform, which results in lower switching losses. It can boost the output voltage to 1.5 times the applied input DC source voltage. Satisfactory inverter operation is ensured by employing twelve-band hysteresis current control. The tuning of the PI controller required for the closed-loop hysteresis current control is achieved by nature-inspired PSO algorithm. A comparative analysis is also performed after obtaining the results applying nature-inspired PSO and conventional Ziegler Nichols (ZN) methods. The effectiveness of the control strategy is verified in the MATLAB Simulink and further validated in experimentusing TMS320F28379D and also with Typhoon Hardware in Loop Technology.
Parents’ and Guardians’ Willingness to Vaccinate Their Children against COVID-19: A Systematic Review and Meta-Analysis

COVID-19 vaccination for children is crucial to achieve herd immunity. This is the first systematic review and meta-analysis to estimate parents’ and guardians’ willingness to vaccinate their children against COVID-19 and identify the determinants of vaccination intention. Systematic research was performed on the two databases (PubMed and EMBASE) from inception to 6 November 2021. Acceptance rates were pooled by use of a random-effects model and all predictors of vaccine acceptance were identified according to the health belief model (HBM) framework. This analysis was registered with PROSPERO (CRD42021292326) and reported in compliance with the PRISMA guidelines. Of 452 identified records, 29 eligible studies were included (N = 68,327 participants). The estimated worldwide vaccination acceptance rate was 61.40% (95% CI: 53.56–68.69%, I2 = 99.3%), ranging from 21.6% to 91.4% across countries and regions. In the determinant assessment, the age of parents and guardians, access to scientific information and recommendations, routine and influenza vaccination behavior, and the willingness of parents and guardians to vaccinate themselves were potentially significant predictors of the vaccination willingness. Given the limited quality and quantity of included articles, future studies with a rigorous design will be necessary for the confirmation of our findings.
Money Well Spent? The Cost-Effectiveness of a Texting Intervention Targeting College Persistence

Abstract Past studies of texting interventions designed to promote college student persistence have given little attention to assessing both the fixed and variable costs of such initiatives. In addition, they typically have not assessed costs relative to the desired outcome(s). In this case study, we assessed the costs of implementing a text messaging program relative to persistence outcomes using a randomized field experiment in one college. The intervention’s cost per student was $18.76 and the cost per text was $0.85 per student. Mean cost-effectiveness ratios per student retained ranged from $1,312 to $750. Sensitivity analyses revealed increases in the number of students texted or gains in academic advisors’ efficiencies both contributed to sizable declines in the cost-effectiveness ratios. We conclude the texting intervention was cost-effective relative to other published interventions that have targeted college persistence.
Differences between official and non-official matches in worst-case scenarios in elite futsal players

Background: ‪This study aimed to compare the worst-case scenarios (WCS) between official (OFF) and non-official (Non-OFF) matches, in different time-periods in an elite futsal team. Material and methods: Twenty-six games were divided into OFF (n = 13) and Non-OFF (n = 13). The WCS were calculated using: two methods, rolling averages (ROLL) and fixed-periods (FIX); four-length epochs (30-s, 1-, 3-, and 5-min); and player load per minute (PL·min-1). Results: Considering ROLL, significant and small differences were found in PL·min-1, with higher intensity in 30-s (p = 0.001; ES = -0.53) and 1-min (p = 0.001; ES = -0.47) in OFF when compared to Non-OFF, but non-significant and small to trivial changes in 3-min (p = 0.060; ES = -0.23) and 5-min (p = 0.605; ES = -0.06) were observed. Regarding FIX, significant and small changes were obtained, with higher intensity in OFF in all time-periods when compared to Non-OFF. Significant differences were found between the two methods (ROLL vs FIX) in 30-s, 1- and 3-min, but not in 5-min. Significant differences, with lower PL·min-1, were observed with increasing time-windows from both methods (p = 0.001). Conclusions: ‪In summary, OFF matches present higher WCS than Non-OFF ones when considering short time-periods, and the FIX method could underestimate the “actual intensity” of the match compared to ROLL.
Identification Chemical Compositions of Lemongrass Plant (Cymbopogon nardus L.) Dawan Tribe, Oenenu Village, North Central Timor Regency

Lemongrass (Cymbopogon nardus L.) is a local natural resource used by the Dawan tribe as an alternative for mosquito repellent. The utilization of these plants cannot be separated from the content of compounds found in these plants. Therefore, it is necessary to analyze the content of bioactive compounds from lemongrass (Cymbopogon nardus L.). This research method includes sample preparation, isolation and identification of compounds, and antioxidant activity analysis. The results of this study that there were three main components of citronella oil, namely geraniol, citronellol, and citronellal, with a higher percentage of geraniol, namely 18.82%. The compounds contained in lemongrass oil have a weak antioxidant activity with IC50 681.48 mg/mL.
An Examination of the Contributions to Loss on a Transonic Turbine Blade in Cascade

Experiments to measure losses of a linear cascade of transonic turbine blades are reported. Detailed measurements of the boundary layer at the rear of the suction surface of a blade and examination of wake traverse data enable the individual components of boundary layer, shock and mixing loss to be determined. Results indicate that each component contributes significantly to the overall loss in different Mach number regimes. Traverses in the near wake of the blade indicate the way in which the wake develops and facilitate examination of the development of the mixing loss.
Accounting for the Emergy Value of Life Cycle Inventory Systems: Insights from Recent Methodological Advances

Emergy, due to its unique ability to translate into a single metric the memory of the geobiosphere exergy (environmental work) supporting any (technological or natural) system, has the potential to offer a new perspective of environmental assessment to support decision-making. Previous work by a number of researchers has pointed out the expected advantages of taking a hybrid approach combining Emergy Evaluation (EME) and Life Cycle Assessment (LCA). In particular, emergy calculation using Life Cycle Inventory (LCI) databases and LCA matrix-based formulation is claimed to have the potential to increase the reliability of emergy-based evaluations and thereby the applicability of the emergy concept in environmental decision-making. The paper points out the main obstacles to overcome in order to reach this consistent integration, highlighting the progresses made so far in this direction, until the most recent practical and operational advancements.
Exploring the Associations between Single-Child Status and Childhood High Blood Pressure and the Mediation Effect of Lifestyle Behaviors

Background: This study aimed to assess the association between single-child status and childhood high blood pressure (HBP) and to explore the role of lifestyle behaviors in this relationship. Methods: This study used data from a cross-sectional survey of 50,691 children aged 7~18 years in China. Linear and logistic regression models were used to assess the relationship between single-child status and HBP, and interactions between single-child status and lifestyle behaviors were also evaluated. Mediation analysis was conducted to detect the mediation effect of lifestyle behaviors. Results: Of the participants enrolled, 67.2% were single children and 49.4% were girls. Non-single children were associated with a greater risk of HBP, especially in girls (OR = 1.11, 95%CI: 1.03~1.19). Meat consumption and sedentary behavior mediated 58.9% of the association between single-child status and HBP (p < 0.01). When stratified by sleeping duration, non-single girls of insufficient sleep and hypersomnia showed a higher risk of HBP (p < 0.05) than single-child peers, but not in those with adequate sleep. Conclusion: Findings suggest that non-single children had an increased risk of HBP, and keeping healthy lifestyle behaviors could help to mitigate the adverse impact in non-single children.
Recently developed electrospinning methods: a review

Conventional electrospinning is an effective and versatile method employed for fabricating nanofibers. However, the relatively low production rate is the major challenge of electrospinning as an economic and scalable method. Recently, several approaches have been developed to ensure the high production rate of nanofibers. This paper has reviewed the latest developed electrospinning methods, such as multi-jet, needleless, bubble, centrifuge and electro-centrifuge systems. Furthermore, the jet formation in centrifugal spinning, as well as electro-centrifuge systems, was investigated through experimental and numerical analysis.
FAKTOR YANG BERHUBUNGAN DENGAN KEJADIAN STUNTING PADA BALITA

Stunting is one of the nutritional problems that adversely affects the quality of life of children in achieving optimal growth and development according to their genetic potential. Stunting can hinder the process of growth and development in toddlers. Chilhood stunting in childhood is the result of chronic malnutrition or past growth failure and is used as a long-term indicator of childhood malnutrition. Stunting is a health problem that is found in many developing countries, including Indonesia. This study aims to determine the factors associated with the incidence of stunting in children under five in the working area of ​​the UPT Puskesmas Tanjung Batu Kepri. This type of research is quantitative with a correlation analysis research design with a cross-sectional approach. The population in this study were all children under five in the working area of ​​the UPT Puskesmas Tanjung Batu Kepri. The samples were taken as many as 97 children under five using consecutive sampling technique. Data collection using primary data using questionnaires and examinations.

There is a relationship between income and the incidence of stunting with P-value = 0.000 <0.1. There was a relationship between ANC visits and the incidence of stunting with P-value = 0.004 <0.1. It is necessary to increase the provision of information to pregnant women and mothers with children regarding the prevention of stunting.
The Effect of Private and Public Health Expenditure on Economic Growth in Sub-Saharan Africa

This study examined the relationship between health expenditure and economic growth in sub-Saharan Africa. The General Method of Moments (GMM) estimation technique was used and the data covered the period 2000-2019 for forty-six countries. The results of the difference GMM-1 and GMM-2 steps indicate that a 1% change in public health expenditure per capita (LPUHE_PC) is associated with a 0.1362% and 0.1521% rise in GDP per capita (GDP_PC) in the short run. The system GMM-1 and GMM-2 steps indicate that a percentage change in LPUHE_PC is associated with a respective 0.0148% and 0.0109% rise in GDP_PC in the short run at a 1% level of significance, on average ceteris paribus. In the long run, the difference GMM-2 step indicates that a 1% change in the LPUHE_PC has a larger positive effect on the GDP_PC (1.34899%) than in the short-run (0.1521%). The result of the system GMM-1 and GMM-2 step indicates that a 1% change in LPUHE_PC has a larger positive effect on the GDP_PC in the long run (0.39967% and 0.24135%) than in the short-run (0.0148% and 0.0109%) respectively. This analysis indicates that a rise in government health spending will stimulate economic growth with a larger effect in the long run than in the short run in Sub-Saharan Africa. Thus, the government should increase health budgetary allocations.
Personality Change Through Digital-Coaching Interventions

A highly relevant but provocative research question is whether and how one can intentionally change personality traits through psychological interventions, given that traits are relatively stable by definition. Recently, research has begun to investigate personality change through intervention in nonclinical populations. One attractive and innovative interventional avenue may lie in using digital applications to guide and support people in their desire to change their personality and trigger change processes. This article provides a rationale for nonclinical personality-change interventions and discusses motivations to change, the potential of using digital applications for intervention efforts, key studies that illustrate this emerging field of research, and future directions.
The influence of age on the occurrence of internal parasites in perch (Perca fluviatilis L.) from Lake Góreckie in Wielkopolski National Park

The European perch (Perca fluviatilis L.) is a common freshwater fish which is widely distributed in Europe and Asia and has been successfully introduced to New Zealand and Australia. It is the intermediate and definitive host of many parasites, especially endoparasites, such as trematodes, cestodes and nematodes (Bikhovskaya-Pavlovskaya and Kulakova,1987; Carney and Dick, 1999; Behrmann-Godel and Brinker, 2005; Wierzbicka et al., 2005; Kuchta et al., 2009). Information concerning the parasites of perch can be found in widely published literature (Rolbiecki, 2006; Halmetoja et al., 2000), but still little is known about aspects such as the age dynamics of infections with endoparasites. Parasites provide a great deal of biological information about their host, regarding migration, differences in diet, and food web structure (Williams et al., 1992; MacKenzie et al., 1995; Marcogliese et al., 2006). On the other hand, parasitism may influence the behaviour of fish (hosts), resulting in changes in their habitat and increasing vulnerability to predators (Seppälä et al., 2008). Infection with parasites increases the relative risk of mortality in the host (Behrmann-Godel and Brinker, 2005). In this paper we determined the occurrence of parasites in perch from Lake Góreckie, Wielkopolski National Park. Perch is common in water bodies and has a diverse diet, and for these reasons it is the definitive or intermediate host of many parasite species. Therefore, this fish species was selected for our study. The influence of age on the occurrence of parasites in perch has not yet been examined in detail. The aim of this study was to answer the following questions: • What parasites occur in perch in Lake Góreckie? • Which species of endoparasites are more frequently observed in perch in Lake Góreckie? • Is there a correlation between the occurrence of the endoparasite and the age of perch?
Further Evaluation of the Effects of a Production Level "Voice-Command" Interface on Driver Behavior: Replication and a Consideration of the Significance of Training Method

This report assesses the extent to which key findings from our initial on-road study (Reimer, Mehler, Dobres & Coughlin, 2013) on driver interaction with a production version, invehicle voice command system replicate, as well as considering whether two differing approaches to introducing drivers to the driver vehicle interface (DVI) impact their pattern of interaction, including driving behavior. An analysis sample of 64 participants, equally balanced by gender across the four age groupings (18-24, 25-39, 40-54, and 55+) specified in the NHTSA (2013) visual-manual guidelines for DVI assessment, was evaluated during manual radio tuning, voice-command assisted radio tuning, and voice-command assisted navigation system interaction consisting of full destination address entry and route cancelation under actual highway driving conditions. The MIT AgeLab auditory presentation / vocal response n-back cognitive demand reference task was also presented. No statistically significant main effects of self-guided vs. structured training condition were found across the tasks as a whole, although clear advantages were evident in tasks requiring memorization of complex command syntax. The basic pattern of results seen in the first study (considering self-reported workload, physiological arousal, driving performance metrics, and glance behavior) largely replicated. Voice recognition was again found to be fairly robust with only 3 out of more than 80 participants unable to participate due to voice recognition issues. For the radio tuning reference task, the voice-command method was associated with lower workload (self-report, heart rate, skin conductance level (SCL)), lower mean glance durations, and a markedly lower percentage of long duration glances than the visual-manual interface. Apparent cognitive processing demand / workload as assessed through heart rate and SCL for the DVI tasks studied fell below the level of the 1-back cognitive reference task. Some voice-command AgeLab Technical Report 2014-2 ©MIT AgeLab 2014 Page 2 of 191 involved tasks, particularly full destination address entry, were associated with a high degree of total eyes off-road time (TEORT). Cognitive demands become more apparent when drivers had difficulty completing activities. Assessment of the “voice” interface in these studies illustrates that in modern DVI’s, attentional draws can be highly multimodal (combinations of visual, manual, auditory, vocal, haptic, etc.). Thus, visual as well as other potential demand sources need to be included in the assessment of voice interfaces.

Primary central nervous system lymphoma in the United States, 1975–2017

Background: Primary central nervous system lymphoma (PCNSL) has received more attention because of an inferior prognosis. Less is known about the incidence rate, histological type, and survival rate of PCNSL, especially in the 2010s. Methods: Data of PCNSL from the Surveillance, Epidemiology, and End Results (SEER) registry database (SEER 9 registries and SEER 18 registries) were used. Incidence was estimated by age, gender, race, site, and histological type. Trends were analyzed using joinpoint regression and described as annual percent change (APC) and average annual percent change (AAPC). Five-year overall survival estimates were compared using log-rank tests. Results: Most PCNSL occurred in the brain, followed by the spinal cord. The most frequent histological type of PCNSL was diffuse large B-cell lymphoma, followed by marginal zone lymphoma. Incidence rate increased from 0.1/100,000 to 0.5/100,000 with an AAPC of 5.3% from 1975 to 2017. Incidence rates varied greatly between the younger and older age population. The 5-year overall survival rates in SEER 9 registries and SEER 18 registries were 30.5% and 37.4%, respectively. Even though the 5-year overall survival rate significantly increased from 27.9% for the 1975–1979 time period to 44.8% for the 2010–2017 time period, survival benefit could not be expected for patients ⩾60 years. The 5-year survival rate for elderly patients was about 30% in the 2010s. Conclusion: With aging, the incidence of PCNSL in the elderly is increased. Over the past decade, no advances have been made in the treatment of elderly PCNSL. Prospective trials with PCNSL are warranted to improve the survival of elderly patients.
