AbstractRockburst forecasting plays a crucial role in prevention and control of rockburst disaster. To improve the accuracy of rockburst prediction at the data structure and algorithm levels, the Yeo–Johnson transform, K-means SMOTE oversampling, and optimal rockburst feature dimension determination are used to optimize the data structure. At the algorithm optimization level, ensemble stacking rockburst prediction is performed based on the data structure optimization. First, to solve the problem of many outliers and data imbalance in the distribution of rockburst data, the Yeo–Johnson transform and k-means SMOTE algorithm are respectively used to solve the problems. Then, based on six original rockburst features, 21 new features are generated using the PolynomialFeatures function in Sklearn. Principal component analysis (PCA) dimensionality reduction is applied to eliminate the correlations between the 27 features. Thirteen types of machine learning algorithms are used to predict datasets that retain different numbers of features after dimensionality reduction to determine the optimal rockburst feature dimension. Finally, the 14-feature rockburst dataset is used as the input for integrated stacking. The results show that the ensemble stacking model based on Yeo–Johnson, K-means SMOTE, and optimal rockburst feature dimension determination can improve the accuracy of rockburst prediction by 0.1602–0.3636. Compared with the 13 single machine learning models without data preprocessing, this data structure optimization and algorithm optimization method effectively improves the accuracy of rockburst prediction.
Mapping Language to Actions and Movement Across Time and Space: New Strategies for Promoting Successful Task Execution
Authors: Ward Sarah , Jacobsen Kristen 
Published: September 2022

Purpose:
This clinical focus article reviews current research on how individuals “map” language to their actions and movement across time and space as a key component of effective task execution and presents clinical recommendations for teaching students with impaired executive functioning to develop this essential “mapping” skill. Because students diagnosed with executive function (EF) challenges are generally not described as having a communication impairment, they frequently do not qualify to receive speech and language therapy in school settings. However, recent research indicates that both verbal and nonverbal language are foundational EF skills, and school-based speech and language pathologists will find that incorporating the language-based interventions for EF challenges outlined here can substantially improve treatment outcomes for all students with EF difficulties.

Conclusions:
We make four language-based treatment recommendations: (a) begin the development of independent EF skills by first introducing the concept of moving from the present to a desired future outcome as a form of “mental time travel” (e.g., start by mentally picturing oneself attaining the end goal of an assignment); (b) instruct students in the importance of picturing, talking about, and gesturing the concrete steps they will take to reach that future goal; (c) focus on developing robust verb vocabularies to make those mental steps as vivid as possible before the actual task execution begins; and (d) develop self-talk implementation intentions to strengthen both the ability to visualize oneself moving toward the future goal and the ability to form a “Plan B” when obstacles arise. We begin by considering a hands-on example of two students with contrasting EF profiles; followed by a review of the research on the four EF components and treatment steps outlined above; and conclude with a clinical model for teaching these four steps in school and treatment settings.

Context.A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. In fact, the existence of a planetary companion has been proposed, as well as contested, around the relatively bright, nearby M3.0 V star AD Leo at the same period as the stellar rotation of 2.23 days.Aims.We further investigate the nature of this signal. We introduce new CARMENES optical and near-IR RV data and an analysis in combination with archival data taken by HIRES and HARPS, along with more recent data from HARPS-N, GIANO-B, and HPF. Additionally, we address the confusion concerning the binarity of AD Leo.Methods.We consider possible correlations between the RVs and various stellar activity indicators accessible with CARMENES. We additionally applied models within a Bayesian framework to determine whether a Keplerian model, a red-noise quasi-periodic model using a Gaussian process, or a mixed model would explain the observed data best. We also exclusively focus on spectral lines potentially associated with stellar activity.Results.The CARMENES RV data agree with the previously reported periodicity of 2.23 days, correlate with some activity indicators, and exhibit chromaticity. However, when considering the entire RV data set, we find that a mixed model composed of a stable and a variable component performs best. Moreover, when recomputing the RVs using only spectral lines insensitive to activity, there appears to be some residual power at the period of interest. We therefore conclude that it is not possible to determinedly prove that there is no planet orbiting in synchronization with the stellar rotation given our data, current tools, machinery, and knowledge of how stellar activity affects RVs. We do rule out planets more massive than 27M⊕(=0.084MJup). Likewise, we exclude any binary companion around AD Leo with M sinigreater than 3–6MJupon orbital periods <14 yr.

Medical Flossing am Sprunggelenk – Effekte auf Bewegungsausmaß, Balance und subjektive Anstrengung
Authors: Lohkamp Monika , Limpach Sam 
Published: September 2022

ZusammenfassungDas Supinationstrauma ist eine der häufigsten Verletzungen bei Sportlerinnen und Sportlern. Dementsprechend ist eine adäquate Prävention wichtig. Bekannte Risikofaktoren sind eine eingeschränkte Beweglichkeit des Sprunggelenks und eine schlechte Balancefähigkeit. Medical Flossing, eine neue Therapiemethode, könnte in diesem Fall sinnvoll eingesetzt werden, da es eine verbesserte Beweglichkeit sowie eine Reintegration der Propriozeption verspricht.Ziel der Studie war, den Effekt von Medical Flossing auf die Dorsalextension des Sprunggelenks und die dynamische Balance bei gesunden Freizeitsportlerinnen und -sportlern zu testen.In der randomisierten kontrollierten Studie führte die Interventionsgruppe eine Bewegungsübung mit Medical Flossing am Sprunggelenk durch, die Kontrollgruppe die gleiche Bewegungsübung ohne Flossing. Primäre Outcomes waren das Bewegungsausmaß der Dorsalextension des Sprunggelenks, gemessen anhand des Weight Bearing Lunge Tests, und die dynamische Balance, gemessen anhand des Y-Balance-Tests. Als sekundäres Outcome wurde die Einschätzung der subjektiven Anstrengung anhand einer Ratingskala erhoben. Eine 2-faktorielle ANOVA mit Messwiederholung wurde angewendet.Zwanzig Sportler*innen nahmen an der Studie teil, 10 in jeder Gruppe. Die Dorsalextension zeigte einen signifikanten Gruppen- und Zeiteffekt mit einem Unterschied von der Prä-Messung zu allen anderen Zeitpunkten. In beiden Gruppen verbesserte sich die postero-laterale Reichweite im Y-Balance Test signifikant zur Prä-Messung, aber es gab keinen Unterschied zwischen den Gruppen. In postero-mediale Richtung gab es einen Zeiteffekt, aber post hoc konnten keine Unterschiede gezeigt werden. In anteriore Richtung gab es keine signifikanten Unterschiede. Die subjektive Anstrengung war in der Interventionsgruppe statistisch signifikant geringer.Flossing, in Kombination mit aktiven Übungen, konnte in dieser Studie bei Freizeitsportlerinnen und -sportlern im Vergleich zu aktiven Übungen ohne Flossing das Bewegungsausmaß verbessern, aber nicht die Balancefähigkeit. Die Übung mit Flossing wurde als weniger anstrengend empfunden.

AbstractThe purpose of this analysis is to assess the use of machine learning (ML) algorithms in the prediction of postoperative outcomes, including complications, recurrence, and death in transsphenoidal surgery. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically reviewed all papers that used at least one ML algorithm to predict outcomes after transsphenoidal surgery. We searched Scopus, PubMed, and Web of Science databases for studies published prior to May 12, 2021. We identified 13 studies enrolling 5,048 patients. We extracted the general characteristics of each study; the sensitivity, specificity, area under the curve (AUC) of the ML models developed as well as the features identified as important by the ML models. We identified 12 studies with 5,048 patients that included ML algorithms for adenomas, three with 1807 patients specifically for acromegaly, and five with 2105 patients specifically for Cushing's disease. Nearly all were single-institution studies. The studies used a heterogeneous mix of ML algorithms and features to build predictive models. All papers reported an AUC greater than 0.7, which indicates clinical utility. ML algorithms have the potential to predict postoperative outcomes of transsphenoidal surgery and can improve patient care. Ensemble algorithms and neural networks were often top performers when compared with other ML algorithms. Biochemical and preoperative features were most likely to be selected as important by ML models. Inexplicability remains a challenge, but algorithms such as local interpretable model–agnostic explanation or Shapley value can increase explainability of ML algorithms. Our analysis shows that ML algorithms have the potential to greatly assist surgeons in clinical decision making.

Published: September 2022

Abstract
Background We aimed to evaluate the presence of sural sparing pattern (SSP) and sensory ratio in pediatric Guillain–Barré syndrome (GBS), their distribution to subtypes, and their relationship with demographic and clinical features with a focus on the disability and muscle strength.
Methods This single-center retrospective study was conducted on pediatric GBS patients of both sexes with 2 years follow-up and two nerve conduction studies in which SSP and sensory ratio were calculated. Three subgroups of SSP were formed by separate calculation of median (SSP-m) and ulnar (SSP-u) and both median and ulnar sensory nerve action potentials (SNAPs; SSP-total). Muscle strength and disability were evaluated with the Medical Research Council (MRC) sum score and Hughes functional grading scale (HFGS), respectively.
Results SSP total was identified in 70.6% (n: 24) of the patients, while sensory ratio >1 was observed in 20 (66.7%) patients. Patients with SSP-m, SSP-u, SSP-total, or sensory ratio >1 had higher HFGS scores, while patients with SSP-m, SSP-u, or SSP-total had lower MRC sum scores. SSP parameters were significantly associated with muscle strength and disability scores in acute motor axonal neuropathy patients.
Conclusion Both SSP and sensory ratio can be used for diagnostic and prognostic purposes. Disability and muscle strength are associated with SSP and sensory ratio in pediatric GBS.

Published: September 2022

AbstractClinicians rely on objective concussion assessments that may be influenced by patient characteristics, creating difficulties in isolating the effect of concussion on patient function. The purpose of our study was to identify characteristics associated with performance on the Sport Concussion Assessment Tool 5th edition (SCAT5) 10-word recall test following adolescent concussion. We evaluated patients seen for care within 14 days of concussion (n=125; 15.2±1.6 years of age, range=11–18 years; 46% female; 6.9±3.4 days post-concussion). Patient demographic (age, sex, medical and concussion history, etc.), injury (timing of presentation, symptom severity, sport-type, etc.), and clinical test (Modified Balance Error Scoring System [mBESS], tandem gait) characteristics were assessed, in addition to SCAT5 immediate and delayed memory testing using the 10-word recall list. Immediate and delayed recall performance was significantly associated with concussion symptom burden and cognitive accuracy during tandem gait, although effect sizes were notably small. Specific variables such as age, sex, diagnosis of ADD/ADHD, and performance on other clinical assessments were not significantly associated with recall performance after controlling for covariates. Further, the 10-word recall list demonstrates specific advantages over previously used 5-word lists by way of decreased ceiling effects and reduced interference of inherent patient characteristics.

Abstract
Objectives The aim of the present study was to evaluate the effects of orthodontic treatment on patients' oral health-related quality of life (OHRQoL) in a population aged 17 to 21 years. The influence of gender and malocclusion severity was also investigated.
Materials and Methods In the present study, 108 patients were enrolled. Each patient completed a questionnaire about oral health impact profile (OHIP)-14 before treatment and after 12 months of treatment. The severity of the initial malocclusion was evaluated through the index for orthodontic treatment need (IOTN).
Statistical Analysis Statistical analysis was performed to assess the presence of difference in OHRQoL score before and after the treatment, and the influence of gender and IOTN score on the observed outcomes.
Results We found no significant differences related to gender regarding their perception of how malocclusion affects the quality of life before orthodontic treatment. Moreover, no significant differences were found between males and females regarding their perception of how orthodontic treatment affects the quality of life 12 months after orthodontic treatment. Also, the analysis showed no statistically significant difference between males and females in the correlation IOTN-OHIP for Grades 2 and 3. A statistically significant difference between males and females was found only in Grade 4, both before (p = 0.046) and after treatment (p = 0.051).
Conclusion Finally, OHIP-14 can be a valuable instrument to assess the perceptions and the expectations of patients toward orthodontic treatment.

Published: September 2022

Objective The objective of this study was to derive profiles of alcohol, tobacco, and recreational drug use during pregnancy for first-time mothers with latent class growth analysis (LCGA) and determine the association of these classes with the risk of adverse pregnancy outcomes (APO).
Study Design A secondary analysis of a prospective cohort of Nulliparous Outcomes in Pregnancy: Monitoring Mothers-to-Be was conducted in eight medical centers across the United States from September 30, 2010, to September 23, 2013. Self-reported use of any alcohol, tobacco, or recreational drugs in the 1 month prior to the visit was assessed at up to four visits throughout pregnancy, and APOs included a composite of preterm birth, hypertensive disorder of pregnancy (HDP), small for gestational age (SGA) infant, or stillbirth, and each adverse outcome separately.
Results Four latent classes were identified from the LCGA for 10,031 nulliparous pregnant women that were on average 26.9 years old (standard deviation [SD] = 5.7) and mostly non-Hispanic White (59.7%). Classes included consistent tobacco users (N = 517, 5.2%), nonusers (N = 8,945, 89.2%), alcohol users (N = 500, 5.0%), and a combination of alcohol/tobacco/drug users (N = 69, 0.7%). Logistic regression demonstrated that the class of tobacco users was more likely to have an APO (odds ratio [OR] = 1.48, 95% confidence interval [CI] = 1.22–1.81), preterm birth (OR = 1.53, 95% CI = 1.15–2.02), and SGA (OR = 1.79, 95% CI = 1.36–2.35) relative to the class of nonusers. The class of alcohol users was more likely to have HDP (OR = 1.37, 95% CI = 1.11–1.70) and less likely to have preterm birth (OR = 0.59, 95% CI = 0.38–0.90) and SGA (OR = 0.61, 95% CI = 0.40–0.93) compared to nonusers.
Conclusion Trajectories of substance use are associated with APOs; thus, interventions to mitigate the use when encountered early in pregnancy are warranted.

Developmental Dysplasia of the Hip Is Not Associated with Breech Presentation in Preterm Infants
Authors: Leonard Samantha P. , Kresch Mitchell J. 
Published: September 2022

Objectives The aim of the study is to (1) determine the incidence of developmental dysplasia of the hip (DDH) in preterm infants born prior to 35 completed weeks' gestation in a breech presentation, and (2) evaluate if the association between breech presentation and DDH in full-term infants holds for premature infants.
Study Design This study design comprises retrospective review of infants born between January 1, 2008, and December 31, 2017, at <35 weeks' gestation and admitted to the NICU. Infants had hip ultrasounds at 4 to 6 weeks' corrected age if they were born in a breech presentation with a stable hip examination. We excluded infants born in a presentation other than breech or vertex, had no documentation of presentation at birth, or if they died within the first year.
Results We included 1,533 infants. Preterm infants <35 weeks' gestation born in the breech versus vertex position had an incidence of DDH of 0.47% (2/428) and 0.36% (4/1,105), respectively. There was no significant difference in the incidence of DDH between infants born in the breech versus vertex position (Chi-square and Fisher's exact tests). The sensitivity, specificity, and positive and negative predictive values of breech presentation in detecting DDH were 33, 72, 0.47, and 99.6%, respectively.
Conclusion There is no association between breech presentation and DDH in preterm infants <35 weeks' gestation. Obtaining hip ultrasounds on preterm infants <35 weeks' gestation born in the breech presentation with a normal hip examination is not recommended.

Published: September 2022

Objective The aim of the study is to evaluate whether pathologic severity of placenta accreta spectrum (PAS) is correlated with the incidence of small for gestational age (SGA) and neonatal birthweight.
Study Design This was a multicenter cohort study of viable, non-anomalous, singleton gestations delivered with histology-proven PAS. Data including maternal history, neonatal birthweight, and placental pathology were collected and deidentified. Pathology was defined as accreta, increta, or percreta. The primary outcome was rate of SGA defined by birth weight less than the 10th percentile. The secondary outcomes included incidence of large for gestational age (LGA) babies as defined by birth weight greater than the 90th percentile as well as incidence of SGA and LGA in preterm and term gestations. Statistical analysis was performed using Chi-square, Kruskal–Wallis, and log-binomial regression. Increta and percreta patients were each compared with accreta patients.
Results Among the cohort of 1,008 women from seven United States centers, 865 subjects were included in the analysis. The relative risk (RR) of SGA for increta and percreta did not differ from accreta after adjusting for confounders (adjusted RR = 0.63, 95% confidence interval [CI]: 0.36–1.10 for increta and aRR = 0.72, 95% CI: 0.45–1.16 for percreta). The results were stratified by placenta previa status, which did not affect results. There was no difference in incidence of LGA (p = 1.0) by PAS pathologic severity. The incidence of SGA for all PAS patients was 9.2% for those delivered preterm and 18.7% for those delivered at term (p = 0.004). The incidence of LGA for all PAS patients was 12.6% for those delivered preterm and 13.2% for those delivered at term (p = 0.8203).
Conclusion There was no difference in incidence of SGA or LGA when comparing accreta to increta or percreta patients regardless of previa status. Although we cannot suggest causation, our results suggest that PAS, regardless of pathologic severity, is not associated with pathologic fetal growth in the preterm period.
