What is the Prevalence of General Anxiety Disorder and Depression Symptoms in Semi-elite Australian Football Players: A Cross-Sectional Study.

BACKGROUND: The prevalence of anxiety and depression symptoms in semi-elite Australian footballers is unknown. The primary objective of this study was to determine the prevalence of generalised anxiety disorder (GAD) and depressive symptoms in semi-elite Australian Football players. Our secondary objective was to explore the association between demographic and football-specific factors with GAD and depressive symptoms. A cross-sectional epidemiological study including 369 semi-elite Western Australian Football League (WAFL) players from the Men and Women's 2022 season (n = 337 men, 91%) was conducted. Symptoms of depression were measured using the Patient Health Questionnaire-9 scale (PHQ-9) and symptoms of GAD with the GAD-7 scale. RESULTS: Our response rate was 82.9%. Thirteen players had missing data. The prevalence of GAD symptoms was 8.5% in men and 28.6% in women (10% overall). The prevalence of depressive symptoms was 20% in men and 57% in women (23% overall). Being a woman (gender) was associated with a sevenfold increased risk of GAD and/or depression symptoms [odds ratio (OR): 7.33, 95% confidence interval (CI): 3.18-16.92; p < 0.001]. Players of 'Aboriginal or Torres Strait Islander' ethnicity were two times more likely to report GAD and/or depression symptoms in comparison to players of 'Australian' ethnicity (OR: 2.13; 95% CI: 1.01-4.49; p = 0.048). Concussion history was not a significant risk factor for GAD or depression symptoms. CONCLUSION: This study demonstrated that approximately 1 in 10 WAFL players met the diagnostic cut-off criteria for probable GAD, and 1 in 5 for probable depression. The prevalence for depression symptoms in this study were far higher than the national average in the comparative age bracket. WAFL women's players also reported a substantially higher prevalence of GAD and depressive symptoms than men, and should be further investigated as a priority by the WAFL.

The Effects of Water-based Exercise Training in People with Type 2 Diabetes.

PURPOSE: To investigate the effects of 8 wk of upright water-based exercise training in people with type 2 diabetes. METHODS: Thirteen participants with type 2 diabetes (54% male; 60.9 ± 9.6 yr, mean ± standard deviation) completed 8 wk of upright water-based exercise training at a moderate intensity (60%-80% of exercise test-derived maximum HR), for 1 h, three times a week (TG). Fourteen participants (64% male; 63.9 ± 9.8 yr) acted as a control group (CG) who maintained their usual activities. Preintervention and postintervention, participants performed cardiopulmonary exercise testing to determine V˙O2peak and one-repetition maximum testing to assess muscular strength. Blood profiles were assessed with standard assays. Body mass index and waist/hip ratio were employed as measures of anthropometry. Endothelium-dependent (brachial artery flow-mediated dilation) and independent (glyceryl trinitrate-mediated) function were assessed using vascular ultrasound. RESULTS: Water-based training increased V˙O2peak (18.5 ± 4.3 mL·kg·min to 21.5 ± 5.4 mL·kg·min) (P = 0.002), overall muscle strength (123 ± 44 kg to 139 ± 43 kg) and leg strength (92 ± 28 kg to 104 ± 29 kg), compared with the CG (P = 0.001). The effect on pectoral strength (31 ± 17 kg to 35 ± 16 kg) was not significantly different to the CG (24 ± 12 kg to 26 ± 14 kg) (P = 0.08). No change was observed in anthropometry, blood profiles, or glyceryl trinitrate-mediated vascular function. Flow-mediated dilation was increased after training (6.1% ± 2.4% to 6.5% ± 3.0%), compared with controls who demonstrated a slight decrease (6.2% ± 1.6% to 5.4% ± 1.6%) (P = 0.002). CONCLUSIONS: Water-based circuit training was well tolerated and appears to be an effective exercise modality for improving aerobic fitness, strength, and vascular function in people with type 2 diabetes.

Osteoarthritis- a systematic review of long-term safety implications for osteoarthritis of the knee.

BACKGROUND: There is no cure for knee osteoarthritis (KOA) and typically patients live approximately 30-years with the disease. Most common medical treatments result in short-term palliation of symptoms with little consideration of long-term risk. This systematic review aims to appraise the current evidence for the long-term (≥12 months) safety of common treatments for knee osteoarthritis (KOA). METHODS: Cochrane Database of Systematic Reviews, Medline and PubMed were systematically searched from 1990 to July 2017, inclusive. Inclusion criteria were 1) peer-reviewed publications investigating treatments for KOA referred to in the Australian Clinical Care Standard and/or Therapeutic Guidelines: Rheumatology 2) specifically addressing safety of the treatments 3) with ≥12 months of follow-up and 4) Downs and Black quality score ≥ 13. RESULTS: Thirty-four studies fulfilled the inclusion criteria. Lifestyle modifications (moderate exercise and weight loss), paracetamol, glucosamine, Intraarticular Hyaluronic Acid (IAHA) and platelet-rich-plasma (PRP) injections have a low risk of harm and beneficial ≥12 month outcomes. Although Nonsteroidal Anti-inflammatory Drugs (NSAIDs) provide pain relief, they are associated with increased risk of medical complications. Cortisone injections are associated with radiological cartilage degeneration at > 12 months. Arthroscopy for degenerative meniscal tears in KOA leads to a 3-fold increase in total knee arthroplasty (TKA). TKA improves primary outcomes of KOA but has a low rate of significant medical complications. CONCLUSIONS: Given the safety and effectiveness of lifestyle interventions such as weight loss and exercise, these should be advocated in all patients due to the low risk of harm. The use of NSAIDs should be minimized to avoid gastrointestinal complications. Treatment with opioids has a lack of evidence for use and a high risk of long-term harm. The use of IAHA and PRP may provide additional symptomatic benefit without the risk of harm. TKA is associated with significant medical complications but is justified by the efficacy of joint replacement in late-stage disease.

Eight-Week Return to Play Following Latarjet Shoulder Reconstruction in an Australian Football Player: A Case Report.

INTRODUCTION: Anterior shoulder dislocation is a common injury in many sports, resulting in extended time lost from play with an extremely high recurrence rate in young athletes playing a high-risk sport. Latarjet shoulder reconstruction is a common surgical procedure used to prevent subsequent dislocation with an expected rehabilitation time frame of between 4 and 6 months before return to play. CASE DESCRIPTION: A 21-year-old male Australian football player experienced 2 left-sided shoulder dislocations before undergoing a left Latarjet shoulder reconstruction. He was assessed clinically and with magnetic resonance imaging, which revealed significant tearing of the anterior labrum. The authors theorized that maximal glenohumeral stability occurs after bony healing of the coracoid onto the glenoid at 6 weeks. The patient then underwent an 8-week structured and graduated rehabilitation program aimed at preventing loss of shoulder range of motion, muscle, and functional capacity and returned to play at 8 weeks postinjury with no complications or recurrence at 12-month follow-up. DISCUSSION: This is the first time an 8-week rehabilitation following Latarjet shoulder reconstruction has been reported. In athletes with anterior glenohumeral dislocation who require accelerated return to play, a Latarjet reconstruction with an 8-week rehabilitation protocol may be considered.

CLINICAL MEASURES OF HIP RANGE OF MOTION DO NOT CORRELATE WITH THE DEGREE OF CAM MORPHOLOGY IN SEMI-ELITE AUSTRALIAN FOOTBALLERS: A CROSS-SECTIONAL STUDY.

BACKGROUND: Clinical testing to determine the presence of a cam morphology is becoming more common however the correlation between hip range of motion and the degree of cam morphology remains controversial in the literature. The prevalence of a cam morphology in athletes has been reported as higher than in the general population but the prevalence of cam morphology has not been reported in Australian Football (AF). PURPOSE: The purpose of this study was to determine the correlation between hip range of motion and hip alpha angle and report the proportion of players with a cam morphology in a sample of AF players. DESIGN: Cross-sectional Study. METHODS: Twenty-one semi-elite AF players (42 hips) from the Peel Thunder Football Club were included in this study. A hip Flexion Internal Rotation (IR) test and a modified maximal squat test using the difference in depth of squat in hip internal and external rotation were used. These measures were then compared to alpha angles on 90 degree Dunn view x-rays. RESULTS: Four of the 42 hips (9.5%) had a cam morphology (alpha angle > 60 degrees). There was no significant correlation between alpha angle and ROM in a Flexion IR test or the difference in modified maximal squat test depth within this sample of players. CONCLUSIONS: The proportion of cam morphology seems to be lower in this sample than the previously reported prevalence in other sports. The lack of correlations between hip range and hip alpha angle in players means that screening hips using clinical measures to detect cam morphology associated with poor hip range of motion may be inaccurate. LEVEL OF EVIDENCE: Level 3a.

The effects of Botulinum Toxin injection in an elite sportsman with Functional Popliteal Artery Entrapment Syndrome: A case report.

BACKGROUND: Botulinum Toxin-A (BoNT-A) is an effective intervention for Functional Popliteal Artery Entrapment Syndrome (FPAES) however, concerns with this intervention include reductions in strength and performance. CASE REPORT: This case presents an elite male athlete with FPAES who underwent BoNT-A injection and the results of testing before and after injection. The athlete experienced a decrease in strength and performance at one week post-injection however, he returned to baseline levels within four weeks. When comparing sprint distance during games, before and after injection, the athlete had an increase in his sprint distance per game post-injection. Finally on ultrasound he had visible medial gastrocnemius denervation atrophy with a decrease in arterial flow velocity at four weeks post-injection. CONCLUSION: BoNT-A may be an effective minimally invasive treatment option for FPAES however, athletes may experience a transient decrease in function following BoNT-A injection and consequently caution must be taken with regard to treatment timing.

A Partial Tear of the Infraspinatus Muscle.

A 29-year-old man experienced right shoulder pain and weakness following a forced abduction and external rotation motion performed during an Australian football game. The following morning, the sports medicine physician referred the player for magnetic resonance imaging to exclude infraspinatus rupture, given the external rotation strength deficit. Magnetic resonance imaging revealed a low-grade partial tear of the medial infraspinatus muscle. J Orthop Sports Phys Ther 2016;46(12):1087. doi:10.2519/jospt.2016.0421.
