Sleep And Positive Emotions In Adolescents With Anorexia Nervosa In Relation To The Covid-19 Pandemic

Purpose: The recent COVID-19 pandemic, and its consequent lockdown measures raised concerns about people’s mental health. Identified vulnerable groups may be especially at risk. This study investigated the impact of this unprecedent situation on sleeping patterns and emotionality in adolescents with anorexia nervosa (AN).Methods: Variations in sleeping patterns and emotionality of 101 adolescents with AN, assessed during the pandemic (Covid-19 Group), and the year before (No-Covid-19 Group) were analyzed. We further investigated these variations over time: before the lockdown, 9 months later and after the lockdown.Results: Adolescents in the Covid-19 Group had significantly higher rates of sleep alterations and lower rates of positive emotions, compared to the No-Covid-19 Group. A higher insomnia severity index score and a tendency to lengthen sleep latency time were also associated with the pandemic period. Considering three different groups of patients over time, the kinetics of the impact of the changes shows that the worsening of values is not strictly limited to the acute lockdown phase but is increasing over time. Conclusions: These sleep and emotionality features could have participated to increase severity and incidence of AN in adolescents during the Covid-19 pandemic. As such, these features could represent therapeutic targets to optimize the care of adolescents with AN, particularly urgent to improve considering the kinetic of the deterioration. Tools such as those provided by cognitive behavioral therapy for insomnia (CBTi) and by the positive psychology seem appropriate to guide clinicians in this context. Level of evidence: Level V, descriptive study (evaluation data retrospectively studied).

Association between Insomnia and Irritable Bowel Syndrome among Adolescents in South Korea: A Quantitative Cross-Sectional Study

Insomnia refers to having difficulty sleeping even when given the opportunity and environment to sleep. Irritable bowel syndrome is a functional bowel disease that is accompanied by abdominal pain and irregular defecation but not organic lesions. Although insomnia and irritable bowel syndrome are pathophysiologically related, studies on their relationship among adolescents are lacking. This study aimed to determine the prevalence of insomnia and irritable bowel syndrome among adolescents and the association between them. In May 2021, a survey was conducted among high school adolescents from Daegu Metropolitan City, South Korea, using the Korean version of the Insomnia Severity Index and the Rome IV diagnostic criteria for irritable bowel syndrome. Data were analyzed using chi-square and Mann–Whitney tests and logistic regression analyses. The incidence of insomnia (Insomnia Severity Index score ≥ 10) was 18.4% (n = 74) while that of irritable bowel syndrome was 10.7% (n = 43). Irritable bowel syndrome was strongly associated with an increased incidence of insomnia (odds ratio = 3.30, 95% confidence interval: 1.66–6.53). Therefore, the association between insomnia and irritable bowel syndrome has relevance in the treatment of insomnia in adolescents.

Prediction across healthcare settings: a case study in predicting emergency department disposition

Several approaches exist today for developing predictive models across multiple clinical sites, yet there is a lack of comparative data on their performance, especially within the context of EHR-based prediction models. We set out to provide a framework for prediction across healthcare settings. As a case study, we examined an ED disposition prediction model across three geographically and demographically diverse sites. We conducted a 1-year retrospective study, including all visits in which the outcome was either discharge-to-home or hospitalization. Four modeling approaches were compared: a ready-made model trained at one site and validated at other sites, a centralized uniform model incorporating data from all sites, multiple site-specific models, and a hybrid approach of a ready-made model re-calibrated using site-specific data. Predictions were performed using XGBoost. The study included 288,962 visits with an overall admission rate of 16.8% (7.9–26.9%). Some risk factors for admission were prominent across all sites (e.g., high-acuity triage emergency severity index score, high prior admissions rate), while others were prominent at only some sites (multiple lab tests ordered at the pediatric sites, early use of ECG at the adult site). The XGBoost model achieved its best performance using the uniform and site-specific approaches (AUC = 0.9–0.93), followed by the calibrated-model approach (AUC = 0.87–0.92), and the ready-made approach (AUC = 0.62–0.85). Our results show that site-specific customization is a key driver of predictive model performance.

The Safety and Efficacy of Pregabalin Add-on Therapy in Restless Legs Syndrome Patients

Pregabalin is increasingly being used as a first-line treatment for symptomatic control of restless legs syndrome (RLS). This study aimed to evaluate the efficacy and safety of pregabalin as add-on therapy in RLS patients already taking dopamine agonists (DA) but still in need of further management. Patients with idiopathic RLS were enrolled, and all had already been prescribed DA for at least 3 months but still had either persistent symptoms, side effects, or comorbid insomnia. An initial dose of 75 mg pregabalin was begun, adjusted as needed, and maintained at a stable dose for 4 weeks, followed by observation for a total of 8 weeks. RLS symptoms and insomnia scores were evaluated before and after add-on pregabalin treatment. Patients were monitored for side effects that could be attributed to pregabalin. A total of 32 RLS patients were enrolled, and 20 subjects remained until the endpoint. After the pregabalin add-on, the mean IRLS score showed significant improvement compared to the baseline (p < 0.001). The insomnia severity index score also improved (p = 0.036), and no serious adverse effects were observed. Our preliminary data suggests the potential for pregabalin as an add-on therapy to DA with regards to both efficacy and safety in patients who have inadequate RLS improvement.

Instability Severity Index Score Does Not Predict the Risk of Shoulder Dislocation after a First Episode Treated Conservatively

The first purpose of this study was to verify the association between Instability Severity Index Score (ISIS) and Recurrent Shoulder Dislocation (RSD) after a first episode treated conservatively. The second aim is to identify the risk factors associated with RSD after a primary acute shoulder anterior dislocation treated conservatively. A total of 111 patients with first traumatic anterior shoulder dislocation treated at a single trauma centre between January 2014 and March 2016 were enrolled. The main predictive variables of risk factors and the ISIS score were calculated. Among the 85 patients included, 26 cases of RSD were observed (30.6%). Considering the whole population, no significant association between ISIS and RSD were reported. Regarding other risk factors, high-risk working activities and rotator cuff injury had a significantly higher RSD risk. Sex, dominant limb, familiar history, hyperlaxity, contact or overhead sports, competitive sport, post-reduction physiokinesitherapy, return to sports activity time, Hill-Sachs lesion, bony Bankart lesion and great tuberosity fracture did not seem to influence the risk of RSD. No correlation between ISIS score and RSD in patients treated conservatively after a first episode of shoulder dislocation were reported. The only risk factors with a significant association to RSD were high-risk working activities and rotator cuff injury.

Inconsistencies in Controlling for Risk Factors for Recurrent Shoulder Instability After Primary Arthroscopic Bankart Repair: A Systematic Review

Background: Failure rates after arthroscopic shoulder stabilization are highly variable in the current orthopaedic literature. Predictive factors for risk of failure have been studied to improve patient selection, refine surgical techniques, and define the role of bony procedures. However, significant heterogeneity in the analysis and controlling of risk factors makes evidence-based management decisions challenging. Purpose: The goals of this systematic review were (1) to critically assess the consistency of reported risk factors for recurrent instability after arthroscopic Bankart repair, (2) to identify the existing studies with the most comprehensive inclusion of confounding factors in their analyses, and (3) to give recommendations for which factors should be reported consistently in future clinical studies. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature was performed in accordance with the PRISMA guidelines. An initial search yielded 1754 titles, from which 56 full-text articles were screened for inclusion. A total of 29 full-text articles met the following inclusion criteria: (1) clinical studies regarding recurrent anterior shoulder instability; (2) surgical procedures performed including arthroscopic anterior labral repair; (3) reported clinical outcome data including failure rate; and (4) assessment of risk factors for surgical failure. Further subanalyses were performed for 15 studies that included a multivariate analysis, 17 studies that included glenoid bone loss, and 8 studies that analyzed the Instability Severity Index Score. Results: After full-text review, 12 of the most commonly studied risk factors were identified and included in this review. The risk factors that were most consistently significant in multivariate analyses were off-track lesions (100%), glenoid bone loss (78%), Instability Severity Index Score (75%), level of sports participation (67%), number of anchors (67%), and younger age (63%). In studies of bone loss, statistical significance was more likely to be found using advanced imaging, with critical bone loss thresholds of 10% to 15%. Several studies found predictive thresholds of 2 to 4 for Instability Severity Index Score by receiver operating characteristic or multivariate analysis. Conclusion: Studies reporting risk factors for failure of arthroscopic Bankart repair often fail to control for known confounding variables. The factors with the most common statistical significance among 15 multivariate analyses are off-track lesions, glenoid bone loss, Instability Severity Index Score, level of sports participation, number of anchors, and younger age. Studies found significance more commonly with advanced imaging measurements or arthroscopic assessment of glenoid bone loss and with lower thresholds for the Instability Severity Index Score (2-4). Future studies should attempt to control for all relevant factors, use advanced imaging for glenoid bone loss measurements, and consider a lower predictive threshold for the Instability Severity Index Score.

ASI Based Identification and Prioritization of Accident Black Spot

The number of motor vehicles on road increased spectacularly which causing major social and transportation problems such as death and economic losses. Eradication of accident blackspots is a crucial part of the road safety approach. So, this issue informed the quest to study and identify the accidental black spot in the context of NH 6. The stretch of 35 km on NH 6 near Pune was considered to identify the black spot. Accident blackspot locations were distinguished through the accident severity index (ASI) method by employing two years of accident data. These identified black spots were prioritized based on their final severity index score. The two most vulnerable black spots out of nine were selected for further analysis and countermeasure process. Conclusively, the accident severity-based framework can effectively correlate the nature of the accident with the type of casualty to provide detailed and accurate black spot location.
