Background Acetabular dysplasia (AD) causes pain, limited function, and development of early hip osteoarthritis. Periacetabular osteotomy (PAO) is a surgical treatment for AD that aims to reposition the acetabulum to reduce pain and improve function. Purpose To examine pain recovery and physical activity (PA) before and during the six months after PAO. Study Design Case series, prospective Methods Individuals with AD scheduled for PAO were enrolled. Pain intensity was evaluated before PAO and at one week and one, three, and six months following PAO. PA levels was evaluated before and six months following PAO using accelerometers (time spent in sedentary behavior, light PA, moderate-to-vigorous PA [MVPA], and daily steps) and the International Physical Activity Questionnaire (IPAQ; time spent in walking and in MVPA). Pain improvements was examined over time following PAO using a repeated-measures one-way ANOVA as well as improvements in PA levels before and six months after PAO using paired-sample t tests. In addition, time spent in MVPA was qualitatively summarized at each time point (before and six months after PAO) measured by both the accelerometers and IPAQ. Results Out of 49 screened participants, 28 were enrolled, and 23 individuals (22 females; age=23.1±7.9 years) completed both study visits. Compared to pre-PAO pain, participants reported significant improvements in pain at one month and onward following PAO (p<0.011). However, PA levels at six months following PAO did not differ from pre-PAO PA levels (p>0.05). Qualitatively, participants reported spending more time in MVPA recorded by the IPAQ (pre-PAO=73.3±150.2 mins/day; six-months after PAO=121.2±192.2 mins/day), compared with MVPA recorded by accelerometers (pre-PAO=22.6±25.2 mins/ day; six-months after PAO=25.0±21.4 mins/day). Conclusions Individuals with AD reported significant pain reduction at one month and up to six months after PAO, but PA levels did not change six months after PAO compared to baseline testing. Future studies should consider examining longitudinal pain recovery and PA improvements over longer periods of time with larger samples of individuals with AD undergoing PAO and identifying modifiable factors to minimize pain and increase PA participation.

Introduction: Individuals with acetabular dysplasia often report hip joint instability, pain, and poor hip‐related function. Periacetabular osteotomy (PAO) is a surgical procedure that aims to reposition the acetabulum to improve joint congruency and improve pain and function. We aimed to examine the influence of presurgery clinical measures on functional recovery following PAO and the associations among clinical outcomes after PAO. Methods: We screened 49 potential participants, 28 were enrolled, and 23 completed both study visits (pre‐PAO and 6 months post‐PAO). We evaluated dynamometer‐measured hip and thigh strength, loading patterns during a squat and countermovement jump (CMJ), pain intensity, and device‐measured physical activity (PA) levels (light, moderate‐to‐vigorous PA [MVPA], and daily steps). We used linear regression models to examine the influence of muscle strength (peak torque; limb symmetry index [LSI]) and loading patterns before PAO on pain intensity and PA levels in individuals 6 months following PAO. Additionally, we used Pearson correlation coefficient to examine cross‐sectional associations among all variables 6 months following PAO. Results: Lower extremity muscle strength and loading patterns during the squat and CMJ before PAO did not predict pain intensity or device‐measured PA levels in individuals 6 months following PAO (p > 0.05). Six months following PAO, higher knee extensor LSI was associated with higher time spent in MVPA (r = 0.56; p = 0.016), higher hip abductor LSI was associated with both lower pain (r = 0.50; p = 0.036) and higher involved limb loading during the squat task (r = 0.59; p = 0.010). Lastly, higher hip flexor LSI was associated with higher CMJ takeoff involved limb loading (r = 0.52; p = 0.021) and higher involved hip extensor strength was associated with higher CMJ landing involved limb loading (r = 0.56; p = 0.012). Conclusion: Six months after PAO, higher hip and thigh muscle strength and strength symmetry were associated with lower pain, higher PA levels, and greater normalized limb loading during dynamic movement tasks.

The purpose of this study was to determine the test–retest reliability and construct validity of tools to assess how balance confidence (BC) and state anxiety (SA) change with progressively increasing walking speeds. Sixteen young adults and 15 older adults attended two sessions. Individuals began walking on a treadmill at 0.4 m/s Participants chose to continue increasing the treadmill speed (up to 2.0 m/s) or to discontinue the protocol while rating their BC and SA after completing each speed. BC at participants' fastest speed attempted demonstrated high and moderate test–retest reliability among young (intraclass correlation coefficient [ICC] =.908) and older adults (ICC =.704). SA for young adults and older adults was good (ICC =.833) and fair (ICC =.490), respectively. Our measures also correlated with measures of dynamic stability while walking for young (r = −.67, p =.008) and older adults (r =.54, p =.046). Our dynamic measures of BC and SA are valid and reliable in young and older adults. [ABSTRACT FROM AUTHOR]

Missing data can significantly influence results of epidemiological studies. The National Health and Nutrition Examination Survey (NHANES) is a popular epidemiological dataset. We examined recent practices related to the prevalence and the reporting of the amount of missing data, the underlying mechanisms, and the methods used for handling missing data in recent doctoral dissertations and subsequent publications using NHANES data as a case study. We also explored missing data handling coverage in top-selling applied statistical textbooks. Thirty-seven doctoral dissertations (published from 2007 to 2017) and 17 subsequent journal articles were included in the analysis. Overall, 29 (78.4%) dissertations did not explicitly state whether they had missing data. Five (62.5%) dissertations reporting missing data did not report an assumed mechanism of missingness. Only one subsequent journal article reported the missing data percent for key variables. 28 (75.7%) dissertations and 16 (94.1%) journal articles reported the use of NHANES sample weights. Of the top-selling 20 applied statistics/biostatistics textbooks examined, 14 did not mention imputation. This sample reflects poor rigor in analysis, reporting, and handling of missing data found among recent graduates and poor coverage in textbooks. Checklist utilization and improvement in statistical training on missing data handling are needed. for this article are available online. [ABSTRACT FROM AUTHOR]

Background: Clinical practice, expert opinion, and evidence-based guidelines recommend daily stretching as first-line treatment for multiple sclerosis (MS) spasticity, but this has not been evaluated by fully powered clinical trials. Objective: To determine whether MS Spasticity: Take Control (STC), a guideline-based program of spasticity education and stretching exercises has different effects on the impact of spasticity than a control program of different spasticity education and range of motion (ROM) exercises. Methods: Ambulatory people with self-reported MS spasticity were randomly assigned to STC or ROM, delivered in same duration, facilitator-led, group classes, face-to-face (F2F) initially and later virtually, due to coronavirus disease 2019 (COVID-19). Multiple Sclerosis Spasticity Scale (MSSS) scores were compared between groups at 1 (primary outcome) and 6 months after interventions. Results: A total of 231 people enrolled. There was no significant difference in MSSS scores between STC and ROM at 1 month (mean difference = 0.28, 95% (confidence interval (CI)) = [−9.45 to 10.01], p = 0.955). There were significant group mean improvements in MSSS scores and most other outcomes at 1 and 6 months. Conclusion: Education with stretching exercises, the first-line recommended treatment for MS spasticity, and education with ROM exercises may both improve MS spasticity to a similar degree. This study debunks the belief that stretching is essential to managing MS spasticity. [ABSTRACT FROM AUTHOR]

Background: Youth violence and related aggressive behaviors have become serious public health issues with physical, economic, social, and psychological impacts and consequences. This study identified and evaluated the characteristics of successful school-based violence prevention programs. Methods: Twenty-six randomized controlled trial (RCT), school-based studies that were designed to reduce externalizing, aggressive, and violent behavior between the 1st and 11th grades were analyzed for assessing the effects of 5 program characteristics by comparing results of intervention groups to control groups (no intervention) after intervention using a meta-analysis. Electronic databases and bibliographies were systematically searched, and a standardized mean difference was used for analysis. Results: There was no significant difference between interventions, although programs that used non-theory-based interventions, focused on at-risk and older children, and employed intervention specialists had slightly stronger effects in reducing aggression and violence. Interventions using a single approach had a mild positive effect on decreasing aggressive and violent behavior (effect size =-0.15, 95% CI =-0.29 to -0.02, p = 0.03). Conclusions: Unlike previous individual study findings, this meta-analysis did not find any differential effects for 4 of the 5 program characteristics. In addition, the significant effect noted was contrary to expectation, exemplifying the complexity of identifying effective program strategies. This study adds to the current literature by assessing the program characteristics of RCT studies in an effort to determine what factors may affect school-based violence prevention program success.

Objectives: In this study, we identify physical activity (PA) benefits and barriers and changes in response to a 12-week interactive voice response (IVR)-supported PA telephone counseling intervention. Methods: Participants (N = 63) completed the Exercise Benefits/Barriers Scale (EBBS) at baseline and post-intervention. Exit interview responses to benefits and barriers items were analyzed qualitatively. Results: High exercise benefits and moderate barriers were reported at baseline. The intervention arm experienced a statistically significant greater improvement in barriers (but not benefits) from baseline to week 12, compared to the control arm. These relationships held when we controlled for sex, age, ethnicity, baseline PA, baseline barriers, and baseline benefits. Themes from interviews corroborated the lack of change in PA benefits and decreases in PA barriers and emphasized that support and accountability helped address barriers related to time and motivation. Conclusions: IVR-supported interventions show promise for improving perceived exercise barriers and possibly exercise benefits. [ABSTRACT FROM AUTHOR]

Crime on college campuses appears related to the physical characteristics and routines of the people occupying that space. Environmental criminology suggests that nodes - locations to and from which people routinely travel - help explain the distribution of crime in a given space. The current study examined the role of nodes in explaining the distribution of property crime on a college campus using 24 months of police incident data. More specifically, using GIS and related tools, we compared the distribution of property crime occurring at locations in a major medical center on the campus with locations in the non-medical side. Results revealed more property crime occurred on the medical side of campus and that differences existed in crime patterns for the two nodes based on time, location and season. We conclude by discussing the utility of GIS in allocating resources and crime prevention strategies for college campuses. [ABSTRACT FROM AUTHOR]

Comparing male and female victims across lethal and non-lethal intimate partner violence (IPV) can provide a better understanding of these incidents and assist policy makers in developing more tailored victim services and prevention programs. To date, little research has examined this issue. This study compares the characteristics that predict female and male IPV victimization. Given the role that law enforcement can play in promoting victim assistance programs, police data are used to explore this issue. This study finds that victim sex differences do exist within and across lethal and non-lethal IPV. These findings are discussed as well as their implications for future policy and research.

Tomohon City is city in the province of North Sulawesi, Indonesia, which is enclave from Regency Minahasa with amount sufficient school many. Some schools located on the edge road main, where vehicles passing by with speed very dangerous height for children the school that will cross way to go or when going home from school. Children are often careless and spontaneous, so they have the potential to become victims of traffic accidents. Evaluation of the implementation of the School Safe Zone (ZoSS) needs to be carried out, so that the behavior of pedestrians and drop-off behavior can be known, whether they have behaved safely or not. Then we can draw conclusions whether the School Safe Zone has been effective in its implementation or not. SD Negeri 2 Tomohon and SD Lentera Harapan Tomohon are located on the edge of the main road so they were chosen as research locations because in front of these two schools there is a School Safe Zone (ZoSS) that needs to be evaluated. These two School Safe Zones will be evaluated based on the Decree of the Director General of Land Transportation Number 3582 / AJ.403 / DRDJ / 20018. The research was conducted for 3 days at each location, and was carried out directly including data on the completeness of School Safe Zone (ZoSS) facilities, data on pedestrian behavior and data on drop-off behavior. Speed data and volume data were taken based on references to the 2023 Indonesian Road Capacity Guidelines (PKJI) which will then be processed to obtain the level of service of the road sections studied. From this study, the data on pedestrian and usher behavior in both research locations can be stated as "not yet safe" with Zcount > Ztable. Based on the results of the service level analysis for the Jl. Sam Ratulangi section (SD Negeri 2 Tomohon), the capacity was obtained 3376 smp/hour, the peak hour volume ranged from 374 smp/hour - 788 smp/hour with a service level of service level B during peak hours. While for the Jl. Makmur section (SD Lentera Harapan Tomohon), the capacity was obtained 3440 smp/hour, the peak hour volume ranged from 705 smp/hour - 985 smp/hour with a service level C during peak hours. Therefore, it is necessary for schools to pay attention to educate students about safety in crossing the road, and for the government, especially the Tomohon city transportation agency, to socialize the intent and purpose of implementing the School Safe Zone (ZoSS) for other road users in order to create comfort and safety for road users.

In the insurance sector, Zero-Inflated models are commonly used due to the unique nature of insurance data, which often contain both genuine zeros (meaning no claims made) and potential claims. Although active developments in modeling excess zero data have occurred, the use of Bayesian techniques for parameter estimation in Zero-Inflated Poisson models has not been widely explored. This research aims to introduce a new Bayesian approach for estimating the parameters of the Zero-Inflated Poisson model. The method involves employing Gamma and Beta prior distributions to derive closed formulas for Bayes estimators and predictive density. Additionally, we propose a data-driven approach for selecting hyper-parameter values that produce highly accurate Bayes estimates. Simulation studies confirm that, for small and moderate sample sizes, the Bayesian method outperforms the maximum likelihood (ML) method in terms of accuracy. To illustrate the ML and Bayesian methods proposed in the article, a real dataset is analyzed. [ABSTRACT FROM AUTHOR]

Before the pandemic, previous research found that online teaching improved teacher face-to-face teaching. Especially in Indonesia, the pandemic has provided an unsatisfactory online teaching experience. Considerably, this study aimed to investigate teachers' perception of face-to-face English teaching after online teaching in a pandemic. The study was designed as a phenomenological study with a sampling method using purposeful random sampling. Sources of data came from interviews with five teachers in urban areas and five teachers in rural areas. Data was supported by documentation and field notes. The study found that teachers perceive faceto-face English teaching practice after the pandemic has changed compared to previous face-to-face teaching. The changes can be seen from three aspects: teaching practice, teaching competencies, and impact on students. [ABSTRACT FROM AUTHOR]

Do school security policies affect how safe parents perceive schools to be, and do they influence parental choice behavior? We address these questions using data from a survey that asked U.S. parents to evaluate hypothetical schools whose security systems and student body racial composition were systematically varied, along with other school characteristics. Results indicate that parents identify schools with intensified security measures as less safe. Furthermore, parents are less willing to enroll their children in schools perceived as unsafe, schools with heightened security, and schools with high black enrollment. We discuss the implications of these findings for educational policy. [ABSTRACT FROM AUTHOR]

Background: Little is known about the relationship between sleep and obesity in young adults, particularly college students. This study examined the relationship between sleep (i.e., sleep duration and quality) and obesity in a large and diverse binational sample of college students.Methods: Analyses were based on a 40-item paper survey from 2016/2017 to 2017/2018 academic years, with a 72% response rate. The samples were 1578 college students aged 18-25 years from five universities (two in the U.S. and three in South Korea). Weight and height were measured objectively; other measures (e.g., health behaviors) were self-reported. Multinomial logistic regression was used to assess the association between sleep duration and independent variables (race/nationality, gender, and BMI). Poisson regression was used to examine the relationship between sleep quality and independent variables.Results: Overall, blacks had a higher adjusted odds ratio (AOR) of short sleep (< 7 h/night) than whites (AOR = 1.74, P < .01); overweight participants had a higher AOR of short sleep than normal weight participants (AOR = 1.52, P < .01); and obese participants had a higher AORs of both short and long sleep (> 9 h/night) (AOR = 1.67, P < .01; AOR = 1.79, P < .05, respectively). Among men, being black, overweight, and obesity were associated with short sleep (P < .05), whereas only obesity was related to short sleep among women (P < .05). In analyses stratified by race and nationality, overweight and obesity were related to short sleep among blacks only (P < .05). Overall, sleep quality (getting enough sleep to feel rested in the morning in the past 7 days) was worse in blacks and South Koreans than whites (P < .05), worse in women than men (P < .05), and worse in participants with obesity than normal weight participants (P < .05).Conclusions: Obesity was associated with both short (< 7 h/night) and long sleep duration (> 9 h/night) and poor sleep quality among all participants. In comparison with whites, blacks were more like to have short sleep, and blacks and South Koreans had worse sleep quality. Further investigations using a larger sample of college students in multiple countries may be helpful to identify target populations who are at a greater risk of obesity and sleep problems.
