Full textAbstract:
The purpose of this qualitative inquiry was to investigate adolescent choral singers’ philosophical beliefs regarding music-making within three different, mid-sized, Midwestern mixed choirs in the United States. Eighteen participants were interviewed for approximately 40 minutes each. Audio files were transcribed and coded with four themes resulting: (1) music-making as a simultaneously feelingful experience for participants; (2) musical knowing as interpersonal knowing; (3) expressed music as expressed feeling; and (4) music-making as enlightening. Participants verified the data through member checks. The presence of a peer de-briefer helped the investigator work through potential ethical issues. The findings reflect many ideas within the field of music philosophy including aesthetic perception, expressiveness by convention, music-making as distinctly human and art as self-unification. Findings also aligned with past studies regarding participants’ expressed meaning of musical experiences including areas such as social growth, expression of emotion, increased self-confidence, and development of personal character. Future suggestions for study include investigating perspectives of individual performers and participants who engage in different music ensembles to strengthen understanding of contextual factors.

Although previous research has investigated the training-specific adaptations to training in adults, there is a paucity of research aimed at investigating these adaptations in adolescent athletes. As such, adolescent athletes’ training-specific adaptations from three different training interventions were investigated in this study. Sixteen adolescent athletes participated in this study, whereby eight performed both training interventions and eight the non-training control. Pre- and post-testing was performed for each intervention with the testing battery: ultrasonography of the vastus lateralis and lateral gastrocnemius, countermovement jump, squat jump, and isometric mid-thigh pull. The resistance training group had large significant increases in isometric mid-thigh pull relative peak force ( p < 0.01, g = 0.85 (−0.01, 1.71)) and vastus lateralis fascicle length ( p = 0.04, g = 0.94 (0.07, 1.80)). The gymnastics and plyometric group demonstrated large significant changes in vastus lateralis pennation angle ( p = 0.03, g = −0.94 (−1.81, −0.08)) and fascicle length ( p = 0.03, g = 1.07 (0.19, 1.95)), and moderate significant increases in lateral gastrocnemius thickness ( p = 0.01, g = 0.63 (−0.21, 1.47)) and eccentric leg stiffness ( p = 0.03, g = 0.60 (−0.24, 1.44)). No significant changes were observed for any variables in the non-training group. The resistance training evoked increases in lower-body force producing capabilities, whereas the gymnastics and plyometric training evoked changes in muscle structure and inherent muscle qualities.

Full textAbstract:
Background The clavicle is the most commonly fractured bone in the body and accounts for 10–15% of all pediatric fractures. Adult patients with complete midshaft clavicle fractures often undergo surgical management. Pediatric patients have a thicker periosteum, more robust blood supply and a greater healing potential. Controversy exists as to whether to treat adolescents with surgery similar to adults versus with a sling as children are treated. Some orthopaedic surgeons are now operating on adolescent clavicle fractures. Objective The objective of the study was to evaluate the outcomes of displaced midshaft clavicle fractures in adolescent who were treated conservatively with a sling. Methods We performed a retrospective chart review of 25 pediatric patients aged 12–16 with complete midshaft clavicle fracture. The outcomes of the study were bony union and functional outcomes such as pain, problems with ADL measured by the modified Disability of Arm, Shoulder, and Hand (DASH) score. Results All patients in our cohort had excellent outcomes at follow-up visits with no complaints of pain or limitations of activities of daily living. Mean follow-up time was 12 months. All patients had perfect modified DASH score of 18. Injury radiographs demonstrated an average of 13 mm shortening initially and 8 mm shortening in final follow-up. Average fracture angulation at final follow-up was 15°. Normal clavicle angulation at the mid shaft is 8°. All clavicles healed completely with no case of malunion or non-union reported. Conclusion Clavicle fractures are common. Although operative treatment of clavicle fractures in the adult population is gaining popularity due to issues in adults with non-union and malunion, the adolescent population is different. The adolescent clavicle fracture demonstrates robust healing and remodeling and complete return to full function. We therefore recommend that adolescent patients aged 12–16 with complete clavicle fracture be treated conservatively with a sling.

Due to successful surgical treatment of congenital heart defects in infants and children, the number of patients who reach the adolescent/adult age is continuously increasing. Aims: The authors sought to identify the short- and medium-term outcomes of reconstruction of right ventricular outflow tract in adolescents and adults who underwent surgical intervention for congenital heart defect in infancy or early childhood. Methods: Between 2001 and 2012, 48 patients (age: 15–39, mean 21 years) (30 tetralogy of Fallot, 11 pulmonary atresia + ventricular septal defect, 6 transposition of great arteries + ventricular septal defect + left ventricular outflow tract obstruction, and 1 truncus arteriosus) had repeat operation because of right ventricular dysfunction. All patients previously underwent right ventricular outflow tract procedures in early childhood. Results: In 31 patients, the small homograft, and in 9 patients the transannular-paths were replaced for “adult-size” homograft. Bioprosthetic pulmonary valve replacement was performed in pulmonary (6 patients) and homograft annuli (2 patients). In 14 patients, resection of the right ventricular outflow tract aneurism was also necessary to be performed. There was no early and mid-time (10 years) mortality. In 97.5% of patients with homograft-re-implantation, there was no need for repeat intervention for 5 years. Conclusions: The right ventricular outflow tract restoration in adolescents and adults is an effective procedure. The reconstruction should be performed in early adolescent period to prevent right ventricular dysfunction. The authors prefer using bioprosthetic pulmonary valve replacement in patients with adult-size pulmonary or homograft annulus. Orv. Hetil., 2012, 153, 1219–1224.

Full textAbstract:
The literature available on patient oriented outcomes of operative management for clavicle fractures in adolescents is fairly limited. The purpose of this study was to analyze the potential of open reduction and internal fixation for displaced mid-shaft clavicle fractures in adolescent patients. We reviewed our series of surgical cases performed in 19 adolescents (mean age: 14.6 years) with displaced unilateral clavicle fractures. Baseline data acquisition included demographic and radiographic variables. A Synthes® LCP clavicular plate was utilized for fixation in all cases. Follow-up data included functional outcome assessment using the Quick Disability of Arm, Shoulder, and Hand Questionnaire (DASH), the simple shoulder test (SST) and additional binary questions. At a mean follow-up of 16 months, quick DASH scores were 4.0 (range: 0-35.5) and mean number of positive yes responses on the SST for all operative patients was 11 (range: 9-12). All cases proved complete radiological union at the 3-month follow-up. All patients returned to full athletics at a mean time of 14 weeks (range: 12-17 weeks). Two patients had minimal hypertrophic scars while no patient was noted with keloid formation or neurovascular deficit. One patient complained of implant prominence and occasional symptoms of discomfort at the 15 month follow-up and opted for implant removal. This was successfully performed with uneventful full recovery. All patients were fully satisfied with their choice for surgical intervention. Anatomical reduction with internal fixation and early mobilization of adolescent displaced clavicle fractures remains a viable treatment option with predictable results and no major complications in reliable hands.

"Could Physical Fitness Be Considered as a Protective Social Factor Associated with Bridging the Cognitive Gap Related to School Vulnerability in Adolescents? The Cogni-Action Project." International Journal of Environmental Research and Public Health 18, no. 19 (September 25, 2021): 10073. http://dx.doi.org/10.3390/ijerph181910073.

The first aim was to compare differences between school vulnerability groups, fitness levels, and their combination in adolescent cognitive performance. The second aim was to determine the mediation role of fitness in the association between school vulnerability and cognitive performance. A total of 912 Chilean adolescents aged 10–14 years participated in this study. The school vulnerability index (SVI) assigned by the Chilean Government was categorized into high-, mid-, or low-SVI. Adolescents were classified as fit or unfit according to their global fitness z-score computed from their cardiorespiratory (CRF), muscular (MF), and speed/agility fitness (SAF) adjusted for age and sex. A global cognitive score was estimated through eight tasks based on a neurocognitive battery. Covariance and mediation analyses were performed, adjusted for sex, schools, body mass index, and peak high velocity. Independent analyses showed that the higher SVI, the lower the cognitive performance (F(6,905) = 18.5; p < 0.001). Conversely, fit adolescents presented a higher cognitive performance than their unfit peers (F(5,906) = 8.93; p < 0.001). The combined analysis found cognitive differences between fit and unfit adolescents in both the high- and mid-SVI levels (Cohen’s d = 0.32). No differences were found between fit participants belonging to higher SVI groups and unfit participants belonging to lower SVI groups. Mediation percentages of 9.0%, 5.6%, 7.1%, and 2.8% were observed for the global fitness score, CRF, MF, and SAF, respectively. The mediation effect was significant between low- with mid-high-SVI levels but not between mid- and high-SVI levels. These findings suggest that an adequate physical fitness level should be deemed a protective social factor associated with bridging the cognitive gap linked to school vulnerability in adolescents. This favourable influence seems to be most significant in adolescents belonging to a more adverse social background.

Full textAbstract:
BACKGROUND Osteochondral lesions of the elbow are a difficult entity to treat in high-demand individuals. Pediatric and adolescent patients who typically present with these lesions are upper extremity athletes involved in high demand sports. There has been relatively limited examination in the literature of these patients’ ability to return to sport at midterm follow-up; particularly after non-osteochondral grafting procedures such as fixation and micro-fracture. The purpose of this study was to determine the mid-term outcomes of lesion treatment in a cohort of pediatric and adolescent patients. METHODS This was a retrospective review of a consecutive series of pediatric and adolescent patients who underwent surgical treatment for osteochondral lesions of the elbow. Patients were treated arthroscopically by a single surgeon from 2012 to 2017. All patients had confirmed osteochondral lesions of their elbow confirmed via MRI and underwent surgical intervention after failure of conservative treatment. Data including age, hand dominance, sporting activity, physeal status, imaging, intra-operative findings, procedure performed, post-operative complications, and return to sport were analyzed. RESULTS Twenty patients (twenty-two elbows) underwent surgical treatment with a mean age of 13.05 (±1.89) years with a mean follow-up 1.9 years. Fifteen males and 5 females were involved in the following sports: baseball (10), gymnastics (3), football (2), lacrosse (1), softball (2), and multi-sport (2). Sixty-three percent of the elbows had open physes at the time of surgical intervention. There were 19 capitellar lesions, 2 trochlear lesions, and 1 radial head lesion. The mean lesion size was 8.5 (±3.7) mm X 8.9 (±3.0) mm. Three patients underwent fixation, and the remainder underwent loose body removal and microfracture. No patients had any post-operative complications and all healed radiographically. One patient (4.5%) underwent a re operation due to repeat injury after gymnastics, and underwent an osteochondral autograft procedure. Thirty-percent of patients did not return to the same sport; forty-percent of baseball players and sixty-six percent of gymnasts. CONCLUSIONS / SIGNIFICANCE Osteochondral lesions of the elbow are a challenging entity to treat. Although arthroscopic intervention can be performed safely and result in radiographic healing, there is a high rate of inability to return to sport in patients involved in high impact upper extremity activity such as baseball and gymnastics with either fixation or lesion debridement /microfracture. Further treatment strategies in these patients including cartilage restoration procedures (i.e. OATS) may be warranted in this population.

Full textAbstract:
Previous studies have reported an association between global measures of bilateral strength and change of direction (COD) ability. Yet, little is known about the association between unilateral muscle strength qualities and COD ability. The aim of this study was to explore the associations between unilateral muscle strength qualities and COD measures (COD speed (CODS) and COD deficit) when matched limb-for-limb (i.e., right limb vs. right limb, left limb vs. left limb) in adolescent team-sport athletes. One hundred and fifteen athletes (56 males, 59 females) active in cricket, netball, and basketball participated in this investigation. Each player performed trials of countermovement jump (CMJ), single-leg hop (SLH), isometric mid-thigh pull (IMTP) and eccentric knee extensor torque (ECC-EXT) to assess muscle strength qualities and 505 and modified 505 (505mod) to evaluate COD ability. Moderate-to-large correlations were observed between SLH and CODS (r = −0.43 to −0.67). Another important finding was that CMJ measures demonstrated moderate-to-large correlations with CODS (r = −0.38 to −0.69) and small-to-moderate correlations with COD deficit (r = −0.24 to −0.45). COD is underpinned by distinct muscle strength qualities and each contribute to specific phases of a COD task. It is therefore likely that such connections exist between muscle strength qualities and COD, with all qualities contributing to overall COD ability.

Full textAbstract:
Objectives: Physeal-sparing techniques for anterior cruciate ligament (ACL) reconstruction have previously been described as safe treatment for adolescent ACL tears in patients with open physes, however few studies to date have reported on return-to-sport or patient reported outcome scores for this specific patient population. This study examined patient reported outcomes in children who underwent a physeal-sparing ACL reconstruction with a minimum of two-year follow-up. Methods: Surgical logs of ACLR performed at a single pediatric/adolescent sports medicine center from 2011 to 2016 were reviewed. Patients with open physes who had ACLR with a hybrid physeal sparing or all-epiphyseal technique were identified. Patients were treated by one of two pediatric sports trained orthopedic surgeons. Their demographics, operative reports, rehabilitative course, time to return-to-play, and post-operative course were retrospectively reviewed. Prospective patient reported outcomes scores, ACL-Return to Sport after Injury (ACL-RSI) and International Knee Documentation Committee (IKDC) or Pediatric IKDC (Pedi-IKDC) and return to sport questionnaire including pre-injury primary sport and competition level, ability to return to pre-injury level of competition following ACLR and subsequent ACL injury were collected. Results: There were 49 patients who met inclusion criteria. Prospectively collected data was obtained for 25 patients at an average of 4.6 (range 2.1-8.0) years following surgery. The average chronological age of patients at time of surgery was 12.8 ± 1.4 years with an average bone age of 13.5 ± 1.3 years. At mid-term follow-up, the average chronological age was 17.2 ± 2.0 years. Average Pedi-IKDC or IKDC score was 94.2 ± 9.2 and ACL-RSI Score was 89.2 ± 18.3. There were 23 patients who considered themselves athletes prior to surgery, 8 patients identifying as recreational athletes competing in town or school leagues and 15 patients identifying as competitive athletes participating on youth travel or club leagues. All patients reported the ability to return to their primary sport following ACLR, with 74% returning to the same or higher level of competition, of which 6 were recreational athletes and 11 were competitive athletes. In addition, 6 patients did not complete outcomes data, but had suffered tear of their ipsilateral (3) or contralateral (3) side and were treated at the same facility. These patients were included in calculation of overall re-tear rate of 12.5% (5 patients) and contralateral tear of 25% (8 patients). Conclusion: Mid-term results of patients treated with a hybrid physeal-sparing or all-epiphyseal ACLR were favorable, with adolescents reporting a high level of functional ability and strong psychological readiness to engage in athletic activities. Re-tear and contralateral tear rates were equivalent to other reported studies. These physeal-sparing techniques demonstrate the ability for young athletes to successfully remain physically active and involved in their sports several years following surgery.

"CLINICAL OUTCOMES AFTER MEDIAL PATELLOFEMORAL LIGAMENT RECONSTRUCTION UTILIZING ALLOGRAFT TISSUE IN PEDIATRIC AND ADOLESCENT PATIENTS: MINIMUM 2-YEAR FOLLOW-UP." Orthopaedic Journal of Sports Medicine 9, no. 7_suppl3 (July 1, 2021): 2325967121S0010. http://dx.doi.org/10.1177/2325967121s00103.
Full textAbstract:
Background: Medial patellofemoral ligament (MPFL) reconstruction has gained popularity as a tool to manage recurrent patellar instability. The use of allograft for reconstruction includes benefits of quicker surgical time and obviating donor-site morbidity. In anterior cruciate ligament (ACL) reconstruction hesitancy exists to use allograft in younger patients based on data demonstrating higher graft failure rates. However, a similar trend of allograft failure has not been demonstrated for reconstruction of the MPFL, which has a lower tensile strength than that of the ACL. Hypothesis/Purpose: The purpose of this study is to evaluate outcomes including recurrent instability after MPFL reconstruction utilizing allograft tissue in pediatric and adolescent patients. Methods: A retrospective review was performed to identify patients of a single surgeon with MPFL reconstructions with allograft for recurrent patellar instability with minimum two-year follow-up. Surgical management was recommended after minimum six weeks of nonoperative management including bracing, physical therapy, and activity modification. Pre-operative x-rays were evaluated to assess physeal closure, lower extremity alignment and trochlear morphology, and Insall-Salvati and Caton-Deschamps ratios. MRIs were reviewed to evaluate the MPFL, trochlear morphology, and tibial tubercle trochlear groove distance (TT-TG). The allograft was fixed with a bioabsorbable screw. Descriptive statistics were used to characterize data. The primary outcome was recurrent instability. Results: 20 patients (23 knees) 14 females (17 knees) with average age 15.8 years (range: 11.5-19.6 years) underwent MPFL reconstruction with allograft with average follow-up of 3.6 years (range: 2.2-5.9 years). Physes were open in 8 knees. Average Insall-Salvati ratio was 1.08 ± 0.16 and Caton-Deschamps index was 1.18 ± 0.15. Eighteen patients were noted to have trochlear dysplasia pre-operatively and TT-TG was 15.4 ± 3.9 mm. The three knees (13.0%) with complications had open physes – two (8.7%) had recurrent instability requiring subsequent operation and one sustained a patella fracture requiring open reduction internal fixation. The average Insall-Salvati of these three patients was 1.26 ± 0.21, Caton-Deschamps was 1.18 ± 0.21, and TT-TG was 18.3 ± 3.5mm. There were no growth disturbances noted post-operatively. Conclusion: MPFL reconstruction using allograft tissue may be performed safely in the pediatric and adolescent population with good outcomes at mid-term follow-up with few complications and low rate of recurrent instability. Anatomic factors for may contribute to recurrent instability and complications post-operatively, though larger numbers are needed for statistical analyses. Further prospective and randomized evaluation comparing autograft to allograft reconstruction is warranted to understand graft failure rates.

Master of Music (Music Education)This thesis documents an investigation of the selection procedures relating to Australian vocal repertoire for mid-adolescent and Higher School Certificate (New South Wales) performers, as used by private singing teachers, school music teachers and singing students. It explores the similarities and differences in the criteria employed in these selections. Semi-structured interviews were the source of data and were conducted with participants from these three categories as well as two composers. The participants evinced highly disparate views. The private singing teachers believed that repertoire should be dictated by the technical ability and physiological constraints of mid-adolescent students and that their role in selecting repertoire was related to the long term vocal growth of each individual. They felt that the school music teachers vetted their repertoire choices with no useful explanation of their reasoning, while the school music teachers noted that students frequently presented repertoire that was too difficult or that was not readily communicated with the audience. The ability of mid-adolescent singers to communicate with and engage an audience was the prime concern of the school music teachers. The students wanted to impress their examiners and believed that infrequently heard repertoire was the best choice, though this was not endorsed by the teachers. There was a perception that the students would perform at their best when they chose repertoire to which they could relate emotionally. Many private singing teachers and school music teachers are not aware of the very broad range of contemporary Australian music and its divergent characteristics. However, there is a shortage of appropriate Australian repertoire that addresses the physiological and emotional needs of mid-adolescent singers.
