Does Performing Partial Repetitions Beyond Momentary Failure Enhance Muscle Hypertrophy In Volume-Load-Equated Calf-Raise Resistance Training?, Amirali Goli, Parsa Attarieh, João Pedro Nunes, Saman Nehegadar, Saaed Khani, Mohmad Fashi, Sajjad Ahmadizad

Research outputs 2022 to 2026

The aim of this study was to determine whether extending traditional calf-raise resistance training sets with partial-range-of-motion (ROM) repetitions in the more dorsiflexed ROM enhances muscular hypertrophy. Sixteen untrained men (25.0±1.7y) completed 10 weeks of unilateral standing calf-raise training (2×/wk) in a within-subject design: one leg performed traditional 10-14RM sets to full-ROM momentary failure (MF; 4-6 sets/session) and the other leg performed half as many sets to full-ROM failure followed by partial-ROM repetitions to a second failure in the more dorsiflexed ROM (PBF; 2-3 sets/session). Total volume-load was equated between conditions; repetitions were counted the same way regardless of the …

Enhancing Physical Performance With Ischemic Preconditioning: A Systematic Review And Meta-Analysis Of Moderators And Performance Outcomes, Yilin Zhang, Kai Xu, Hao Kong, Mingyue Yin, Chenghao Liu, Yun Xie, Liam Kilduff, Gustavo R. Mota, Olivier Girard

Research outputs 2022 to 2026

This study examined the effects of ischemic preconditioning (IPC) on physical performance, considering the influence of timing, warm-up (WU), participant characteristics, and IPC protocols structure. A total of 90 trials (1,439 participants) were retrieved from three databases and assessed using PICOS criteria. Multilevel meta-analyses with cluster-robust variance adjustments were conducted to calculate pooled effect sizes (Hedge’s g). Risk of bias and certainty of evidence were assessed using the RoB 2 tool and GRADE framework. IPC produced a trivial but significant improvement in physical performance (g = 0.13, P < 0.01), which persisted after excluding SHAM effects (g = 0.10; P < 0.01). Significant improvements were observed for maximum repetitions, time to failure, and power output, but not for jump ability, strength, or oxygen uptake. Comparable benefits were found for anaerobic (g = 0.15) and aerobic (g = 0.10) exercise, with greater effects in males and less-trained participants. Performance was further enhanced when IPC was followed by WU (g = 0.16), with the optimal IPC-to-WU interval being ~42 minutes. Without WU, the effective IPC window narrowed to 6–7 minutes. In practice, IPC can enhance physical performance, independently of sham effects, moderated by sex, training level, and WU. For competition or testing, the most effective strategy appears to be 3 or 4 × 5-min IPC protocol, followed by a 42-min interval, standardized warm-up, and endurance testing. For mechanistic studies, WU should be excluded, and testing conducted 6-7 minutes post-IPC. Future research should target women, middle-aged individuals, and elite athletes.

Sex Differences In Sleep, Circadian Rhythms, And Alzheimer’S Disease Pathology In The Appxps1 Mutant Knock-In Mouse, Carrie E. Johnson

University of Kentucky Doctoral Dissertations

Decades of research have demonstrated that sleep and circadian rhythm disruptions increase with age and are associated with increased Alzheimer’s Disease (AD) risk. Women experience more sleep and circadian disruptions with age, especially throughout the menopausal transition, and more women than men have AD. The molecular mechanisms underlying biological sex, sleep and circadian disruptions, and AD are largely unknown. Most research has focused on the build-up of toxic amyloid-beta (Aβ) in the brain [which is a cleavage fragment of the full-length amyloid beta precursor protein (APP)] alongside of loss of circulating gonadal hormones. To investigate these possibilities and others, we …

Reflections From A Community Capacity Building Forum To Support People Bereaved By Suicide, Colleen Carlon, Jacquie Tarrant, Marie Eckersley, Priscilla Vindin

Research outputs 2022 to 2026

An estimated half the population may be impacted by suicide loss. The combination of grief and trauma makes the experience particularly complex. Recognised as the most stigmatised of all sudden losses people bereaved by suicide are in sociocultural contexts that disrupt constructive grief processes and create barriers for help seeking and supportive responses. Effecting change in this context poses a significant health promotion challenge. Social workers in the South West Region of Western Australia sought to develop and deliver a unique postvention approach aimed at strengthening the self-support capacity of people bereaved by suicide while building broader community capacity for …

Frontline Aspiration Versus Stent Retriever Thrombectomy For M2 Occlusions: Insights From The Star Registry, Michael Gaub, Joshua Osbun, Et Al.

2020-Current year OA Pubs

BACKGROUND: Recent trials have furthered uncertainty regarding the endovascular benefit for medium vessel occlusions (MeVO). Stent retrievers (SR) were employed in the first attempt in most interventional arm participants. We sought to compare outcomes in acute MCA M2 occlusions between frontline aspiration and SR, and to delineate procedural and anatomical covariates associated with differential treatment effect.

METHODS: Retrospective analysis of a multicenter stroke thrombectomy cohort identified cases of MT for M2 occlusions. Unmatched and propensity score-matched (PSM) cohorts were generated comparing frontline aspiration to standalone and combined SR. The primary outcome was functional independence (mRS 0-2) at 90 days. Recanalization, …

A Survey-Based Assessment Of Treatment Preferences For Distal Radius Fractures In Participants Aged 65 Years And Older, Zayd Al Rawi, Elizabeth Graesser, Lindley B Wall

2020-Current year OA Pubs

PURPOSE: The management of distal radius fractures (DRF) in patients aged ≥65 years is debated because there is evidence that operative and nonsurgical treatment yield similar outcomes 1 year after injury. When more than one reasonable treatment option exists, shared decision-making between the patient and physician should be used. This study elicited preferences for the treatment of DRF using a survey of participants aged ≥65 years.

METHODS: A survey for participants ≥65 years was administered using Amazon Mechanical Turk. Participants were presented with a theoretical scenario in which they sustained a DRF, followed by two treatment options (surgery or casting) …

Cutibacterium Adaptation To Life On Humans Provides A Potential C Acnes Infection Biomarker, Md Shafiuddin, Wen-Chi Huang, Gabriel William Prather, Jeffrey Ryan Anton, Andrew Lawrence Martin, Sydney Brianna Sillart, Jonathan Z Tang, Michael R Vittori, Michael J Prinsen, Jessica Jane Ninneman, Chandrashekhara Manithody, Jeffrey P Henderson, Alexander W Aleem, Ma Xenia Garcia Ilagan, William H Mccoy 4th

2020-Current year OA Pubs

Propionibacteriaceae appear to have adapted to life on humans during the domestication of cattle. These microbial immigrants formed the genus Cutibacterium, and a descendent of those microbial trailblazers (C acnes) now dominates 25% of human skin. C acnes colonization of human skin requires the protein RoxP. Although all Cutibacteria encode this adaptation to life on humans, nothing like RoxP has been found in any other organism. In this study, we report an extensive assessment of 21 RoxP orthologs, which identified conserved molecular surfaces linked to heme-dependent oligomerization and low pH stability. Our investigation suggests how RoxP helps C acnes dominate …

Mutations In Hsp40 Co-Chaperone Change The Canonical Interdomain Interactions Stimulating Lgmdd1 Myopathy, Ankan K Bhadra, Geetika Aggarwal, Anshuman Jaysingh, Daniel Chen, Jil Daw, Conrad C Weihl, Heather L True

2020-Current year OA Pubs

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …

Airway Management In Emergency Department Thoracotomy: A Narrative Review, Aaron J Lacy, Adam Liebendorfer, Sarah M Guess, Rami S Al-Aref, Anthony P Kronfli, Rachel E Armstrong, Amelia W Maiga, Alexander Bracey, Ryan N Barnicle

2020-Current year OA Pubs

INTRODUCTION: Emergency department thoracotomy (EDT) is a high-risk, life-saving intervention for patients in traumatic cardiac arrest. A critical component of EDT is airway management, typically performed by emergency physicians, yet formal guidance regarding optimal strategies remains limited. Airway management in this setting is uniquely complex due to concurrent anatomic injury, physiologic instability, and the procedural demands of thoracotomy.

DISCUSSION: Endotracheal intubation (ETI) during EDT presents multiple challenges. Anatomic difficulties may arise from facial or cervical trauma, restricted positioning, and the presence of cervical collars. Cognitive load is heightened by the chaotic, multidisciplinary environment, requiring strategies such as pre-briefing, checklists, and …

Influence Of Obesity And Insulin Resistance With Hepatic Steatosis On The Human Plasma Lipidome, Max C Petersen, Gordon I Smith, Aaron M Armando, Xiong Su, Oswald Quehenberger, Edward A Dennis, Samuel Klein

2020-Current year OA Pubs

Insulin resistance accompanied by hepatic steatosis is a common complication of obesity. In an effort to identify plasma lipids that could be biomarkers or causes of insulin resistance with steatosis in people with obesity, we evaluated the plasma lipidome in three distinct groups separated by adiposity, hepatic steatosis, and insulin sensitivity, assessed by using the hyperinsulinemic-euglycemic clamp procedure: i) insulin-sensitive lean (ISL, n = 13); ii) insulin-sensitive obese (ISO, n = 14); and iii) insulin-resistant obese with hepatic steatosis (IROS, n = 13). We evaluated 759 complex lipid species in 16 subclasses (including phospholipids, glycerolipids, sphingolipids, acylcarnitines, and cholesteryl esters) …

Identifying Disparities In Same-Day Surgery Cancellations: Impact Of Race And Socioeconomic Factors In A Pediatric Health System, Nicole M Santucci, Daniel Alligood, Amanda Maytin-Hevia, Danyi Wang, Kelly Chilson, Jesse Vrecenak, Andrew Yeh, Colin A Martin

2020-Current year OA Pubs

PURPOSE: Same-day surgery (SDS) cancellations have significant implications on patients and hospitals. This study aimed to identify demographic and socioeconomic factors that impact SDS cancellations across a single pediatric health system.

METHODS: A case-control retrospective review captured patients (age < 18) who underwent SDS procedures from July 2022 to August 2024. Patients were included if they underwent any procedure at three operative sites: a tertiary pediatric academic hospital (PAH) and two outpatient surgery centers (OSC). Patients whose SDS was cancelled (n = 2,034) were compared to those whose surgeries proceeded as scheduled (n = 25,573). Patient zip codes were matched to Child Opportunity Index (COI) 2.0 data.

RESULTS: The overall SDS cancellation rate was 7.37 %, with a significantly higher rate observed at the PAH compared to OSC (11.4 % vs 53 %, p < 0.001). Patients with cancelled cases were more likely to identify as Black and have the lowest quintile COI (p < 0.001). Cancelled in preop and no shows were two reasons with the most racial disparities. In a sub-analysis comparing cancelled cases between operating sites, PAH cancelled patients tended to be Black (23.8 % vs 11.7 %, p < 0.001) and have very low COI (20.1 % vs. 10.6 %, p < 0.001).

CONCLUSION: SDS cancellation rates are significantly higher amongst patients who identify as Black and reside in low opportunity neighborhoods. Disparities in cancellation rate are more significant in patients scheduled at the urban PAH compared …

Research outputs 2022 to 2026

Purpose: This study emphasizes the growing significance of destination attributes in shaping the experiences and behaviours of gastronomy and culinary tourists. Understanding both core and complementary attributes of a gastronomy tourism destination is crucial for its sustainable development. However, there is a lack of a reliable measurement for tourists’ perceived attributes of gastronomy tourism destinations (PAGTD). Therefore, the purpose of this study is to develop a scale to measure tourists’ PAGTD. Design/methodology/approach: The study systematically followed the scale development and validation process, using three samples (Sample 1, n = 200; Sample 2, n = 204; and Sample 3, n = …

The Power Of Role-Modelling: White Teacher Educators Normalising Anti-Racism And Cultural Reflexivity For White Pre-Service Teachers, Mary-Anne Macdonald, Sarah Booth, Helen Mills, Robert Somerville

Research outputs 2022 to 2026

Every child has a right to feel culturally safe in schools, yet for countless Indigenous students this is not the case. Many White pre-service teachers in Australia enter initial teacher education with a limited understanding of racial identity, Indigenous knowledge or White anti-racism. This autoethnographic study applies Social Cognitive Theory and the Theory of Planned Behaviour to understand the role of the White teacher educator in racial conscientisation of White pre-service teachers. We examine how White teacher confidence in enacting anti-racist behaviours builds when White teacher educators role-model the professional approaches which White teachers can use to teach about race …

Taylorkan-Vit: Parameter-Efficient Vision Transformers For Medical Image Classification, Kaniz Fatema, Dr. Emad Mohammed, Dr. Sukhjit Singh Sehra

Theses and Dissertations (Comprehensive)

Effective and interpretable classification of medical images remains a critical challenge in computer-aided diagnosis, particularly in data-scarce and resource-constrained clinical settings where traditional deep learning models prove impractical. This study addresses the fundamental barrier to Vision Transformer adoption in medical imaging—massive parameter counts and data requirements—through a systematic two-phase methodology. Phase 1 evaluates three spline-based Kolmogorov–Arnold Network (KAN) variants to identify the optimal nonlinear approximation function for parameter-efficient medical image classification: SBTAYLOR-KAN (B-splines with Taylor series), SBRBF-KAN (B-splines with Radial Basis Functions), and SBWAVELET-KAN (B-splines with Morlet wavelets). Comprehensive experiments across brain MRI, chest X-rays, and tuberculosis datasets—without any image …

Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch

Theses and Dissertations (Comprehensive)

BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …

The Relationship Between Interoceptive Awareness And Eating Disorder Symptomatology, Madelyn G. Johnson

Electronic Theses & Dissertations (2024 - present)

Interoceptive awareness (IA; e.g., the ability to perceive and interpret internal bodily sensations) is increasingly recognized as central to eating disorder (ED) psychopathology, yet findings remain mixed regarding whether heightened IA is protective or maladaptive. Across two studies using a sample of 654 college students (Mage = 18.74, SD = 1.56; 46% White; 58% female) from a large northeastern U.S. university, we examined (1) how specific IA facets relate to ED symptom severity, and (2) whether anxiety sensitivity (AS) helps explain these associations. In Study 1, linear regressions predicting Eating Disorder Examination Questionnaire–7 (EDE-Q7) scores showed that nearly all MAIA-2 …

Moderators Of Subjective Distress And State Body Image During Open And Blind Weighing, Danielle E. Peters

Electronic Theses & Dissertations (2024 - present)

Objective: Body image disturbances are central to eating disorder (ED) pathology and are often addressed through exposure-based methods, such as open weighing. Open weighing is recommended in evidence-based ED treatments, but many clinicians and patients prefer blind weighing. It may be that pre-treatment patient characteristics may influence how distressed they feel by open and blind weighing. As such, the present study aimed to 1) compare how open and blind weighing impact subjective distress and state body image, and 2) examine whether self-weighing tendencies, body avoidance, body checking, body checking-related beliefs, intolerance of uncertainty, and ED psychopathology moderate the relationship between …

Key Processes Involved In The Vortex Alignment Of Sheared Tropical Cyclones, Luis O. Hernandez

Electronic Theses & Dissertations (2024 - present)

Tropical cyclones (TCs) are challenging to forecast when under vertical wind shear (VWS). VWS tilts a TC’s vortex, creating asymmetries in its structure that impedes intensification. Although work has been done to conceptualize and understand how TCs evolve under shear and how they axisymmetrize and intensify, vortex alignment remains a complex and unresolved topic. The goal of this study is to assess what physical processes are important to tilt reduction and how these processes evolve in weak TCs. Using the Hurricane Analysis Forecast System Model-B (HAFS-B) 2.1, a case study on two storms, Hurricane Earl (2022) and Hurricane Lee (2023) …

The Impact Of Downdraft Ventilation On Tropical Cyclone Intensity And Structure Using Aerial Reconnaissance Observations, Nicholas E. Johnson

Electronic Theses & Dissertations (2024 - present)

Tropical cyclone (TC) intensity can be challenging to predict since it is modulated by many physical processes. One of these processes is ventilation: the injection of relatively cool, dry environmental air into the warm core of a TC that acts as “anti-fuel”, inhibiting intensification and increasing uncertainty with intensity forecasts. While ventilation has been examined in numerical modeling studies, there have been a limited number of observational studies investigating ventilation. The two primary objectives of this dissertation are to develop methods for measuring downdraft ventilation from aerial reconnaissance observations and to use those observations to better understand how ventilation affects …
