Predicting adolescents' continuation in club sports: A prospective cohort study of the importance of personal and contextual motivational factors in five sports in Denmark.

Purpose: The purpose of this prospective cohort study was to investigate the influence of types of motivation, basic psychological needs satisfaction and of a coach-created motivational climate on continued participation in youth sports across types of sport, competitive levels, ages, and gender.

Methods: Participants were 7110 adolescent (age 12-20 years) members of leisure time club organized in basketball, handball, football, badminton, and gymnastics in Denmark. Motivational regulation was measured with BRSQ-6, basic psychological needs satisfaction and frustration were measured with PNSS-S, and coach-created climate was measured with the EDMCQ-C.

Use of Direct Oral Anticoagulants Among Patients With Hip Fracture Is Not an Indication to Delay Surgical Intervention.

Objectives: To compare outcomes in patients on direct oral anticoagulants (DOACs) treated within 48 hours of last preoperative dose with those with surgical delays >48 hours.

Design: Retrospective cohort study.

Setting: Three academic Level 1 trauma centers.

Antibiotic prophylaxis following low-velocity gunshot fractures: an updated review.

Purpose: Low-velocity gunshot fractures (LVGFs) are a common type of gunshot-induced trauma with the potential for complications such as infection and osteomyelitis. The effectiveness of antibiotic therapy in LVGFs remains uncertain, leading to ongoing debate about the appropriate treatment. In this review, we evaluate recent updates on the current understanding of antibiotic therapy in LVGFs, how previous studies have investigated the use of antibiotics in LVGFs, and the current state of institutional policies and protocols for treating LVGFs with antibiotics.

Factorial validity, predictive validity and measurement invariance of the Danish version of the coach-created Empowering Disempowering Motivational Climate Questionnaire (EDMCQ-C).

Purpose: The purpose of this study was to translate and validate a Danish version of the coach-created Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ-C), retest the factor structure and provide further investigation into the psychometric properties in terms of measurement invariance across gender, age and competitive level, reliability and predictive validity.

Methods: The participants were 1719 male and 551 female Danish football players 12-20 years of age ( = 14.81) playing at recreational, medium and elite levels.

Outcomes of fixation of Vancouver B periprosthetic fractures around cemented versus uncemented stems.

Background: The incidence of periprosthetic femur fracture (PPFF) in the setting of total hip arthroplasty (THA) is steadily increasing. We seek to address whether there is a difference in outcomes between Vancouver B fracture types managed with ORIF when the original stem was a press-fit stem versus a cemented stem.

Methods: In this retrospective cohort study at a level 1 trauma center, we identified 136 patients over 65 years-of-age with Vancouver B-type fractures sustained between 2005 and 2019.

Measurement invariance of the empowering and disempowering motivational climate questionnaire-coach in youth sport.

The purpose of this study was to test the measurement invariance (across five languages, two time points, and two experimental conditions) of the empowering and disempowering motivational climate questionnaire-coach (EDMCQ-C; Appleton et al., 2016) when completed by 9256 young sport participants ( age = 11.53 years, = 1.

Perfectionism and performance-related psychobiosocial states: The mediating role of competition appraisals.

Using the multi-states (MuSt) theory as a framework, the present study focused on the individual (personality) antecedents of psychobiosocial states. Psychobiosocial states comprise emotional subjective experiences and their correlates (cognitive, motivational, volitional, bodily, motor-behavioural, operational, and communicative), that can be functional for performance (helpful) or dysfunctional (harmful). Specifically, we examined the relationships between two perfectionism dimensions (perfectionistic strivings and concerns) and functional and dysfunctional psychobiosocial states.

The associations between motivational climate, basic psychological needs and dropout in volleyball - A comparison across competitive levels.

The purpose of this study was to investigate the importance of motivational climate for the satisfaction of psychological needs and dropout in recreational, intermediate and elite volleyball. Seven thousand nine hundred thirty six volleyball players from all 321 volleyball clubs across Denmark were invited to participate in the study. Three thousand three thirty answered the questionnaire and 2150 were included in the analysis.

CDKL5 kinase controls transcription-coupled responses to DNA damage.

Mutations in the gene encoding the CDKL5 kinase are among the most common genetic causes of childhood epilepsy and can also give rise to the severe neurodevelopmental condition CDD (CDKL5 deficiency disorder). Despite its importance for human health, the phosphorylation targets and cellular roles of CDKL5 are poorly understood, especially in the cell nucleus. Here, we report that CDKL5 is recruited to sites of DNA damage in actively transcribed regions of the nucleus.

Outcomes After Operative Fixation of Vancouver B2 and B3 Type Periprosthetic Fractures.

Objectives: The incidence of periprosthetic femur fracture in the setting of total hip arthroplasty is steadily increasing. Although the traditional dogma is that loose femoral components must be revised, we propose that in a frail geriatric population, anatomic reduction and fixation of Vancouver B2 and B3 periprosthetic fracture variants can restore stem stability and provide similar outcomes as revision arthroplasty.

Design: Retrospective cohort study.

Perceptions of Motivational Climate and Association with Musculoskeletal Injuries in Ballet Dancers.

Objective: Sports science has identified the trainer-athlete relationship in the etiology of injuries. We aimed to investigate: 1) the association between empowering (EMC) and disempowering (DMC) motivational-climate and musculoskeletal injuries in ballet, and 2) if EMC moderates the association between DMC and injuries.

Methods: A cross-sectional cohort survey-study was conducted online among ballet dancers (>18 yrs old) reporting acute and overuse injuries of the previous 2 years.

Lack of Surgeon Standardization on Implant Selection in Ankle Fracture Fixation May Increase Costs and Decrease Contribution Margin.

Background: Surgical standardization has been shown to decrease costs without impacting quality; however, there is limited literature on this subject regarding ankle fracture fixation. Methods. Between October 5, 2015 and September 27, 2017, a total of 168 patients with isolated ankle fractures who underwent open reduction, internal fixation (ORIF) were analyzed.

Social Environmental Antecedents of Athletes' Emotions.

The coach-created motivational climate influences variations in athletes' motivation and emotional experiences. The present study aimed to examine social environmental antecedents of athletes' emotions. Participants ( = 262, 52% female, age = 22.

The efficacy of an anti-protrusio plate in patients with anterior column posterior hemitransverse and associated both column acetabular fractures.

Introduction: Acetabular fractures in the elderly population are particularly challenging for orthopedic fracture surgeons to treat. Anterior column posterior hemitransverse (ACH) and both column (BC) fractures account for over 70% of these injuries in geriatric patients. Nonoperative management of these injuries has a mortality of about 79% and patients generally have a minimal chance of return to independent living.

A Limited Fixation, Olecranon Sparing Approach, for Management of Geriatric Intra-Articular Distal Humerus Fractures.

Purpose: We propose that geriatric comminuted intra-articular distal humerus fractures can be effectively treated with a limited fixation approach aimed at achieving varus/valgus stability with columnar fixation, but allowing intra-articular comminution to heal by secondary congruency against an intact olecranon, thus avoiding an olecranon osteotomy.

Methods: Fifty-six elderly patients with AO 13-C type fractures, who underwent surgical fixation with ≥12-months of follow-up were retrospectively reviewed. Thirty patients were treated with intra-articular open reduction internal fixation (ORIF) with an olecranon osteotomy and 26 patients were treated with our limited fixation (L-ORIF) approach.

Examining the Mediating Role of Motivation in the Relationship between Multidimensional Perfectionism and Well- and Ill-Being in Vocational Dancers.

Perfectionism is considered to be an important personality factor within the dance context given the high number of dancers whose psychological health is influenced by its consequences. The relationship between perfectionism and dancers' well- and ill-being can be mediated by a range of variables. The present study explores the role of forms of motivation (i.

Validation of the Lithuanian Version of the Coach-Created Empowering and Disempowering Motivational Climate Questionnaire (EDMCQ-C).

Based on Duda's conceptualization of the motivational climate, the Empowering and Disempowering Motivational Climate Questionnaire-Coach (EDMCQ-C) is a recently developed scale that assesses junior athletes' perception of the social environmental dimensions proposed by achievement goal theory and self-determination theory. The goal of the current investigation was to evaluate the Lithuanian translation of the EDMCQ-C and more broadly extend the validity and reliability of this questionnaire in sport participants. 712 adolescents from different sport teams in Lithuanian were the participants in this study.

Measurement of eroded dentine tubule patency and roughness following novel dab-on or brushing abrasion.

Objectives: To investigate the effect of dab-on or brushing of stannous-fluoride SnF2 or sodium-fluoride NaF dentifrice on eroded dentine tubule patency, surface and inter-tubular dentine roughness, using Confocal-Laser-Scanning-Microscopy (CLSM), Atomic-Force-Microscopy (AFM), Energy-Dispersive-X-ray-Spectroscopy (EDX), Scanning-Electron-Microscopy (SEM) and Contact-Profilometry (CP).

Methods: 75-polished human dentine samples were prepared and eroded in agitated 6% citric acid to expose patent tubules and 'initiate' DH. Samples were randomly allocated into 5 intervention groups; artificial saliva control (1); electric tooth-brushing with NaF (2) or SnF2 (3), and dab-on application of NaF (4) or SnF2 (5).

Novel Confocal-Laser-Scanning-Microscopy and conventional measures investigating eroded dentine following dentifrice dab-on and brushing abrasion.

Objectives: To validate novel non-contacting Confocal-Laser-Scanning-Microscopy (CLSM) methodology with conventional Contacting Profilometry (CP) measures investigating brushing or dab-on of stannous-fluoride dentifrice on early aggressive dentine erosion.

Methods: 75 polished human dentine samples were prepared and eroded in agitated 6% citric acid then randomly allocated into 5 intervention groups; artificial saliva control (1); controlled use of a pressure sensitive counter-rotating oscillatory powered toothbrush with sodium-fluoride NaF (2) or stannous-fluoride SnF (3), and dab-on application of NaF (4) or SnF (5). Samples underwent three cycles of intervention and 2-min agitated 6 % citric acid challenges.

The utility of post-operative hip radiographs in patients treated with hip hemiarthroplasty for femoral neck fractures.

Background: Patients treated with hip hemiarthroplasty for low energy femoral neck fractures routinely undergo hip radiographs at each postoperative clinic visit regardless of history and physical findings. No studies to date have evaluated the effectiveness of this accepted practice. The goal of this study was to identify the postoperative utility of both history and physical (H/P) and hip radiographs in the treatment course of patients treated with hip hemiarthroplasty for low energy femoral neck fractures.

Implant cut-out following cephalomedullary nailing of intertrochanteric femur fractures: Are helical blades to blame?

Introduction: Implant cut-out remains a common cause of cephalomedullary nail (CMN) failure and patient morbidity following surgical treatment of intertrochanteric femur fractures. Recent studies have suggested an increased rate of CMN cut-out with helical blades as opposed to lag screws. We compared rates of overall cut-out between helical blades and lag screws and used bivariate and multivariate analysis to determine the role of proximal fixation method among other variables on risk for cut-out.
