Anterior Cruciate Ligament Hybrid Remnant Preservation Reconstruction Demonstrates Similar Outcomes As Traditional Reconstruction After 6 Months: A Randomized Control Trial, Joshua P. Castle, Eleftherios L. Halkias, Brittaney Pratt, Ashley Frei, Matthew A. Gasparro, Vasilios Moutzouros

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry

Senior Honors Theses

Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …

Emotionally Concussed: The Impact Of Pre-Existing Anxiety On Concussion Recovery, Grace Szucs

Honors Theses

Recent advances in concussion research have shed light on numerous mental and physiological factors that may complicate concussion recovery. Systematic reviews of the existing literature have found that premorbid mental health conditions such as depression and anxiety may be a predictor of complicated concussion recovery, but studies have not had an appropriate design to isolate anxiety or depression as a predictor of lengthened recovery. This study investigated if athletes with a history of premorbid anxiety and/or depression would have a longer time of recovery than athletes without this history. Male and female athletes from a Division-1 athletic department treated for …

Resistance Training Effectiveness On Body Composition And Body Weight Outcomes In Individuals With Overweight And Obesity Across The Lifespan: A Systematic Review And Meta-Analysis, Pedro Lopez, Dennis R. Taaffe, Daniel A. Galvão, Robert U. Newton, Elisa R. Nonemacher, Victória M. Wendt, Renata N. Bassanesi, Douglas J. P. Turella, Anderson Rech

Research outputs 2022 to 2026

To systematically review and analyze the effects of resistance-based exercise programs on body composition, regional adiposity, and body weight in individuals with overweight/obesity across the lifespan. Using PRISMA guidelines, randomized controlled trials were searched in nine electronic databases up to December 2020. Meta-analyses were performed using random-effects model. One-hundred sixteen articles describing 114 trials (n = 4184 participants) were included. Interventions involving resistance training and caloric restriction were the most effective for reducing body fat percentage (ES = −3.8%, 95% CI: −4.7 to −2.9%, p < 0.001) and whole-body fat mass (ES = −5.3 kg, 95% CI: −7.2 to −3.5 kg, p < 0.001) compared with groups without intervention. Significant results were also observed following combined resistance and aerobic exercise (ES = −2.3% and −1.4 kg, p < 0.001) and resistance training alone (ES = −1.6% and −1.0 kg, p < 0.001) compared with no training controls. Resistance training alone was the most effective for increasing lean mass compared with no training controls (ES = 0.8 kg, 95% CI: 0.6 to 1.0 kg, p < 0.001), whereas lean mass was maintained following interventions involving resistance training and caloric restriction (ES = ~ − 0.3 kg, p = 0.550–0.727). Results were consistently observed across age and sex groups (p = 0.001–0.011). Reductions in regional adiposity and body weight measures were also observed following combined resistance and aerobic exercise and programs including caloric restriction (p < 0.001). In conclusion, this study provides evidence that resistance-based exercise programs are effective and should be considered within any multicomponent therapy program when caloric restriction is utilized in individuals with overweight or obesity.

Modulating Tumour Hypoxia In Prostate Cancer Through Exercise: The Impact Of Redox Signalling On Radiosensitivity, Malcolm Brown, Amélie Rébillard, Nicolas H. Hart, Dominic O’Connor, Gillian Prue, Joe M. O’Sullivan, Suneil Jain

Research outputs 2022 to 2026

Prostate cancer is a complex disease affecting millions of men globally. Radiotherapy (RT) is a common treatment modality although treatment efficacy is dependent upon several features within the tumour microenvironment (TME), especially hypoxia. A hypoxic TME heightens radioresistance and thus disease recurrence and treatment failure continues to pose important challenges. However, the TME evolves under the influence of factors in systemic circulation and cellular crosstalk, underscoring its potential to be acutely and therapeutically modified. Early preclinical evidence suggests exercise may affect tumour growth and some of the benefits drawn, could act to radiosensitise tumours to treatment. Intracellular perturbations in skeletal …

Oxygen Deprivation Masks For Training, Brittany M. Hanlon

Student Publications

Oxygen deprivation masks are being advertised towards athletes as a piece of fitness equipment that can simulate the effects of high altitude, as well as a respiratory muscle training device. Studies that investigated the claims as to whether ODMs increased VO2max and improved endurance were looked into. Experimental data did not find that the use of these masks increased VO2max, nor was there any supporting data to prove that it improved endurance. The function of ODMs as a training tool to increase respiratory muscle strength was also examined. There were contradicting results between the three different studies examined. One study …

Psychosocial Outcomes Of Orthopedic Injuries: An Analysis Of The Relationship Between The Athlete And The Athletic Trainer, Hannah Barnett

Honors Projects

An analysis on the impact of the level of social support from athletic trainers on the outcomes of orthopedic injuries in athletes. The foundational model for this research is Wiese-Bjornstal’s Integrated Model (1998). This model examines the effect of athletes’ emotional responses on their recovery. Social support from the athletic trainer can help mediate negative emotional responses and encourage positive emotional responses, which is why social support is crucial to recovery. Athletes with higher levels of perceived social support from their athletic trainers had more success with rehabilitation. This report consists of a review of the existing literature on psychosocial …

Identifying And Reporting Position-Specific Countermovement Jump Outcome And Phase Characteristics Within Rugby League, John J. Mcmahon, Jason P. Lake, Paul Comfort

Research outputs 2022 to 2026

The countermovement jump (CMJ) has been suggested to be an important test of neuromuscular performance for rugby league (RL) players. Identifying force platform-derived CMJ variables that may be more applicable to RL positions (e.g., forwards and backs) has yet to be fully explored in the scientific literature. The aim of this study was to identify RL position-specific CMJ force-time variables. Specifically, we aimed to compare select forcetime variables from the countermovement (i.e., the combination of unweighting and braking) and propulsion phases of the CMJ between the global forwards and backs positional groups. We also aimed to compare typical (i.e., jump …
