Ware, Jennifer Schafer, Anuj Sehgal, Utpal Bose, Michelle J. Colgrave, Melinda Y. Hardy, Jason A. Tye-Din, Robert P. Anderson

Research outputs 2022 to 2026

Background & Aims: Celiac disease is an immune-mediated enteropathy triggered by gluten ingestion. The effect of very small gluten exposures remains uncertain, contributing to international variations in food-labeling standards. Interleukin 2 (IL2) rises rapidly after gluten ingestion, serving as a biomarker of immune activation. We aimed to identify the lowest gluten dose that elicits a measurable IL2 response and accompanying symptoms in treated celiac disease. Methods: We conducted a randomized double-blind, placebo-controlled adaptive dose–response trial in adults with biopsy-proven celiac disease on a gluten-free diet for >2 years. Participants (n = 51; median age, 52 years; 69% were female) underwent …

Longitudinal Prediction Of Bmi Using Explainable Ai: Integrating Polygenic Scores, Maternal, Early-Life And Familial Factors, Fuling Chen, Phillip E. Melton, Kevin Vinsen, Trevor Mori, Lawrence Beilin, Rae Chi Huang

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.

The cortical asymmetry index evaluates the cortical thickness asymmetry between hemispheres. We investigated cortical asymmetry index in asymptomatic and symptomatic mutation carriers of autosomal dominant Alzheimer's disease to explore the brain asymmetry within the Alzheimer's disease continuum. Sixty baseline T1-weighted MRI scans were obtained from the Clinic Barcelona cohort. Baseline and longitudinal MRI data from 564 participants within the dominantly inherited Alzheimer network observational study were used as an independent, confirmatory cohort. Cerebrospinal fluid and plasma neurofilament light chain levels were included when available. Cortical thickness was calculated using Freesurfer and cortical asymmetry index was calculated via an open-source pipeline. …

Reverse End-To-Side Triceps To Axillary Nerve Transfer For Treatment Of Axillary Nerve Palsy After Reverse Total Shoulder Arthroplasty, Mitchell S. Mologne, Michele Christy, Zachary D. Randall, Christopher J Dy

2020-Current year OA Pubs

Nerve injuries are uncommon, yet significant complications following reverse total shoulder arthroplasty (rTSA), with the axillary nerve being most frequently injured. We report a case of a 67-year-old female who developed persistent motor dysfunction and decreased sensation in the axillary distribution following rTSA for a comminuted proximal humerus fracture. Electrodiagnostic studies confirmed right axillary nerve injury with reduced motor unit recruitment. After no improvement in deltoid function at three months following rTSA, we discussed treatment options for the patient, who opted for surgical intervention. Based on intraoperative findings, we performed a reverse end-to-side triceps-to-axillary nerve transfer. Postoperative evaluations over a …

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 …

UNLABELLED: Molecular signatures predict prognosis in hepatocellular carcinoma, but their relevance to transarterial radioembolization (TARE) with yttrium-90 (90Y) is unknown. We aimed to identify baseline and treatment-induced pathways associated with response and nominate biomarkers. Ten transcriptomically diverse human liver cancer cell lines were exposed to escalating activities of glass 90Y microspheres for 10 days. Normalized AUC values quantified sensitivity. Whole-transcriptome RNA sequencing at baseline and after treatment was analyzed with elastic net regression and gene set enrichment. Findings were corroborated by qRT-qPCR and exploratory analysis of pretreatment tumor samples from patients undergoing TARE. Liver cancer cell line responses to 90Y …

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) …

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 …

Excellent Outcomes In Feasibility Study Of Radiation-Free Conditioning And Transplant In Pediatric Severe Aplastic Anemia, Mithra Lakshmi Narasimhan, Irem Eldem, Jeffrey J Bednarski, Ginny L Schulz, Robert J Hayashi, Shalini Shenoy

2020-Current year OA Pubs

Severe aplastic anemia (SAA) is treated with a hematopoietic cell transplant (HCT) in the presence of an HLA-matched sibling donor (MSD) with disease-free survival (DFS) of >90%. In the absence of an MSD, immunosuppressive therapy (IST) can induce remission but concerns for relapsed/refractory disease and clonal hematopoiesis persist. IST failure is an indication for HCT. Modern HCT approaches target barriers such as graft rejection (GR), graft-versus-host disease (GVHD), and transplant-related toxicities. Traditionally, total body irradiation (TBI) inclusive HCT conditioning helps decrease GR, but the use of TBI in children increases concerns for late effects such as malignancies. To describe outcomes …

Atomic Models Of The Toxoplasma Cell Invasion Machinery, Jianwei Zeng, Yong Fu, Pengge Qian, Wei Huang, Qingwei Niu, Wandy L Beatty, Alan Brown, L David Sibley, Rui Zhang

2020-Current year OA Pubs

Apicomplexan parasites, responsible for toxoplasmosis, cryptosporidiosis and malaria, invade host cells through a unique gliding motility mechanism powered by actomyosin motors and a dynamic organelle called the conoid. Here, using cryo-electron microscopy, we determined structures of four essential complexes of the Toxoplasma gondii conoid: the preconoidal P2 ring, tubulin-based conoid fibers, and the subpellicular and intraconoidal microtubules. Our analysis identified 40 distinct conoid proteins, several of which are essential for parasite lytic growth, as revealed through genetic disruption studies. Comparative analysis of the tubulin-containing complexes sheds light on their functional specialization by microtubule-associated proteins, while the structure of the preconoidal …

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 …

Inter-brain synchrony (IBS), measured by hyperscanning, refers to the synchronization of multiple individuals' brain activities during social interactions. Traditional fNIRS-based hyperscanning suffers shortcomings like low spatial resolution and high susceptibility to superficial interference, causing imprecise estimation of IBS in complex social tasks. This study aims to fill the knowledge gap by comprehensively assessing diffuse optical tomography (DOT), an enhanced alternative to fNIRS, can benefit hyperscanning studies of complex social interactions. Sixteen dyads were engaged in both collaborative and individual tangram puzzle tasks, and their brain activities were recorded simultaneously using DOT and fNIRS. We found that DOT demonstrated significantly stronger …

Mouse Alport Podocytes Are Susceptible To Aav9 Transduction In Vivo, Meei-Hua Lin, Kohei Omachi, Joshua F Begin, Jennifer L Richardson, Jeffrey H Miner

2020-Current year OA Pubs

INTRODUCTION: Alport syndrome features a defective glomerular basement membrane (GBM) due to variants in COL4A3, COL4A4, and COL4A5. The most severe forms, which lack the GBM's collagen α3α4α5(IV) network, progress from hematuria in early childhood to proteinuria, chronic kidney disease, and kidney failure by the age of ∼30. As a monogenic disease without specific treatments, and with podocytes being the only glomerular cells that synthesize collagen α3α4α5(IV), the ability to efficiently deliver genes to Alport podocytes could open up new possibilities for treatment.

METHODS: As a proof-of-concept study, we investigated whether podocytes in X-linked Alport mice were susceptible to transduction …
