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, …

Medical Student Research Symposium

Fear-based disorders, including anxiety and posttraumatic stress disorder, are more prevalent in females than males. Steroid hormones (e.g., estradiol) are involved in fear extinction learning and later recall—a process implicated in the pathophysiology of fear-based disorders. Fear-based disorders commonly emerge during the transition from childhood to adolescence, a period marked by the onset of puberty and a natural increase of steroid hormones. Here, we examined the effects of puberty, sex, and their interaction on extinction recall and underlying neural circuitry in youth. Eighty-five youth (6-17 years, 46% female) completed a two-day Pavlovian fear extinction paradigm while undergoing functional magnetic resonance …

Medical Student Research Symposium

Introduction: Urethral stricture treatment has high recurrence rates and adjunct injectable agents have been explored. Amniotic membranes (AM) promote apoptosis of pro-inflammatory cells, prevent differentiation of pro-fibrotic cells, and decrease scar formation. These tissues generated interest in reconstructive urethral surgery. Thus, we performed urethral dilation combined with micronized AM injection in urethral scar tissue for treatment of urethral stricture.

Materials and Methods: Adult males with strictures ≤12Fr in diameter and ≤2 cm in length, International Prostate Symptom Score (IPSS) ≥11 and maximum flowrate <15 ml/s. Reconstituted 100mg micronized AM was injected at the time of urethral dilation. Primary study end point was anatomical success (≥14Fr by cystoscopy) at 6 months. Secondary end points were questionnaires, flow rate, and post void residual. Outcomes assessed at baseline, 5 days, 14 days, 3 months, and 6 months post-injection. Safety was analyzed.

Results: Ten men, mean age of 52 ± 15 years, were included. There were 7 patients with …

The Role Of Vigorous And High Intensity Interval Training Physical Activity Counseling In Prenatal Care, Emily Lau, Brendan T. Lynch, Sonia Hassan Mar 2023

The Role Of Vigorous And High Intensity Interval Training Physical Activity Counseling In Prenatal Care, Emily Lau, Brendan T. Lynch, Sonia Hassan

Medical Student Research Symposium

Background: Physical activity is becoming a more common component of preventative medicine and patient counseling; however, the prevalence of physical activity counseling and specific social determinants of health have prevented women, namely prenatal patients, from receiving this counseling from their providers1. Physical activity, including high intensity interval training (HIIT), has been shown to be feasible for implementation in patient counseling3 and shown to be safe for pregnant women, even into the third trimester2. We hypothesize that the current percentage of patients, including prenatal patients, being counseled on physical activity is lacking. In addition, we hypothesize …

Lysosomal Zn 2+ Release Triggers Rapid, Mitochondria-Mediated, Non-Apoptotic Cell Death In Metastatic Melanoma, Wanlu Du, Mingxue Gu, Meiqin Hu, Timothy Nold, Prateeksunder Pinchi, Wei Chen, Michael Ryan, Ahmed Bannaga, Haoxing Xu

Medical Student Research Symposium

During tumor progression, lysosome function is often maladaptively upregulated to match the high energy demand required for cancer cell hyper-proliferation and invasion. Here, we report that mucolipin TRP channel 1 (TRPML1), a lysosomal Ca2+ and Zn2+ release channel that regulates multiple aspects of lysosome function, is dramatically upregulated in metastatic melanoma cells compared with normal cells. TRPML-specific synthetic agonists (ML-SAs) are sufficient to induce rapid (within hours) lysosomal Zn2+-dependent necrotic cell death in metastatic melanoma cells while completely sparing normal cells. ML-SA-caused mitochondria swelling and dysfunction lead to cellular ATP depletion. While pharmacological inhibition or genetic silencing of TRPML1 in …

Identifying Predictors For Inflammation-Induced Preterm Birth: A Murine Study, Tzu Ning Liu Bs, Jose Galaz Md, Nardhy Gomez-Lopez Phd

Medical Student Research Symposium

Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality worldwide. A large proportion of preterm deliveries is affected by intra-amniotic inflammation, which can occur in the presence (intra-amniotic infection) or absence (sterile intra-amniotic inflammation) of microbes. Studies have shown an association between intra-amniotic inflammation, cervical shortening, and changes in the cervicovaginal microbiome. However, their causal relationships are unknown. This study aims to determine the causality of intra-amniotic inflammation, cervical shortening, and cervicovaginal microbiome alterations.

Methods: Pregnant C57BL/6 dams received an ultrasound-guided intra-amniotic injection of an endotoxin lipopolysaccharide (LPS) or the alarmin interleukin-1 alpha (IL-1 alpha) on 16.5 …

Norepinephrine Regulation Of Spatial Memory Using The Barnes Maze In Male And Female Rats, Serena Simpson, Ali Gheidi Phd, Nareen Sadik, Cameron J. Davidson Phd, Shane A. Perrine Phd

Medical Student Research Symposium

The role of norepinephrine (NE) in learning and memory has been extensively studied, yet its contribution remains to be clarified. This study aimed to investigate the role of NE on spatial learning and memory in female and male rats using a Barnes maze assay. We used N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4), a specific noradrenergic neurotoxin that can cross the blood brain barrier, to deplete NE stores. We hypothesized that brain NE ablation would attenuate spatial learning and memory in rats. Loss of NE by DSP-4 was determined by measuring NE (and dopamine and serotonin) levels in several brain regions using HPLC. For the …


Intrabody-Mediated Postsynaptic Recruitment Of Camkiiα Improves Memory, Anthony Chifor, Jeongyoon Choi Dr., Joongkyu Park Dr. Jun 2022

Intrabody-Mediated Postsynaptic Recruitment Of Camkiiα Improves Memory, Anthony Chifor, Jeongyoon Choi Dr., Joongkyu Park Dr.

Medical Student Research Symposium

Long-term potentiation (LTP), the selective strengthening of specific synapses based on recent activity, has widely been accepted as the biological mechanism responsible for learning and memory. N-methyl-D-aspartate receptors (NMDARs) play a critical role in LTP, which when activated, result in a surge of postsynaptic intracellular calcium levels. The calcium rise during LTP results in the activation of Ca2+/calmodulin-dependent kinase II alpha (CaMKIIa), which consequently enacts multiple cellular effects that ultimately result in the strengthening of synaptic connections. Previous work has examined the effects of CaMKIIa overexpression in rat hippocampi on spatial memory, however, significant but limited improvement in …

Characterization Of Abin-1 In The Traumatically Injured Brain, Aaron Orellana, Alana C. Conti

Medical Student Research Symposium

Traumatic brain injury (TBI) is associated with chronic pain and persistent neuroinflammation. Opioids are often prescribed in order to relieve pain symptoms, but recent evidence suggests that their use negatively impacts the neuropathology of TBI leading to behavioral impairments and exacerbated neuroinflammation. The de-ubiquinating enzyme tumor necrosis factor alpha-induced protein (TNFAIP)3 or A20, inhibits the inflammatory signaling transcription factor nuclear factor (NF)-kB leading to attenuation of the inflammatory response. A20-binding inhibitor of nuclear factor kB (ABIN-1), which physically interacts with A20, also plays a role in the inhibition of NF-kB and is poorly researched in the central nervous system (CNS). …
