The Feasibility Of Percutaneous Externally Assembled Laparoscopic Nephrectomy: A New Surgical System, Benjamin West, Jerry Thomas, Mohamed Keheila, Nazih Khater, Samuel Abourbih, Salim Cheriyan, Matthew Pierce, Duane D. Baldwin, Jim Shen

Loma Linda University Student Journal

Laparoendoscopic single-site (LESS) nephrectomy provides excellent cosmetic outcomes, but is technically challenging due to loss of triangulation and increased instrument collision. A novel Percutaneous Externally Assembled Laparoscopic (PEAL) surgical system was developed to simplify minimally invasive surgery while providing a nearly scarless outcome. In this study, the feasibility of the PEAL system for nephrectomy was determined.

Comparing The Vaginal Wall Sling With Autologous Rectus Fascia And Polypropylene Sling On Outcome And Patient Satisfaction, Mohamed Keheila, Salim Cheriyan, Jim Shen, Catalino J. Bautista, Josianne Bailey, Kevin Kim, Marina Germanos, Isaac Kelly, Matthew Pierce, Andrea Staack

Loma Linda University Student Journal

Since 2011 FDA safety update on transvaginal synthetic mesh for treatment of stress urinary incontinence (SUI) and pelvic organ prolapse (POP), providers are encouraged to counsel patients on risks related to synthetic mesh slings, such as dyspareunia, erosion, and extrusion. As an alternative to synthetic slings patients often choose autologous slings. We aim to compare outcome and patient satisfaction in patients, who received an autologous vaginal wall sling (VWS), rectus fascia sling (RFS), or synthetic suburethral sling (SSS) for treatment of SUI.

Articles, Abstracts, and Reports

BACKGROUND: Endovascular treatment with mechanical thrombectomy (MT) is beneficial for patients with acute stroke suffering a large-vessel occlusion, although treatment efficacy is highly time-dependent. We hypothesized that interhospital transfer to endovascular-capable centers would result in treatment delays and worse clinical outcomes compared with direct presentation.

METHODS: STRATIS (Systematic Evaluation of Patients Treated With Neurothrombectomy Devices for Acute Ischemic Stroke) was a prospective, multicenter, observational, single-arm study of real-world MT for acute stroke because of anterior-circulation large-vessel occlusion performed at 55 sites over 2 years, including 1000 patients with severe stroke and treated within 8 hours. Patients underwent MT with or …

Bayesian Prediction Intervals For Assessing P-Value Variability In Prospective Replication Studies, Olga A. Vsevolozhskaya, Gabriel Ruiz, Dmitri Zaykin Dec 2017

Bayesian Prediction Intervals For Assessing P-Value Variability In Prospective Replication Studies, Olga A. Vsevolozhskaya, Gabriel Ruiz, Dmitri Zaykin

Biostatistics Faculty Publications

Increased availability of data and accessibility of computational tools in recent years have created an unprecedented upsurge of scientific studies driven by statistical analysis. Limitations inherent to statistics impose constraints on the reliability of conclusions drawn from data, so misuse of statistical methods is a growing concern. Hypothesis and significance testing, and the accompanying P-values are being scrutinized as representing the most widely applied and abused practices. One line of critique is that P-values are inherently unfit to fulfill their ostensible role as measures of credibility for scientific hypotheses. It has also been suggested that while P-values …

Reading Hospital Interventional Radiology

BACKGROUND: The post-thrombotic syndrome frequently develops in patients with proximal deep-vein thrombosis despite treatment with anticoagulant therapy. Pharmacomechanical catheter-directed thrombolysis (hereafter "pharmacomechanical thrombolysis") rapidly removes thrombus and is hypothesized to reduce the risk of the post-thrombotic syndrome.

METHODS: We randomly assigned 692 patients with acute proximal deep-vein thrombosis to receive either anticoagulation alone (control group) or anticoagulation plus pharmacomechanical thrombolysis (catheter-mediated or device-mediated intrathrombus delivery of recombinant tissue plasminogen activator and thrombus aspiration or maceration, with or without stenting). The primary outcome was development of the post-thrombotic syndrome between 6 and 24 months of follow-up.

RESULTS: Between 6 and 24 …

Structural Insights Into The Potency Of Sk Channel Positive Modulators, Young-Woo Nam, Razan Orfali, Tingting Liu, Kunqian Yu, Meng Cui, Heike Wulff, Miao Zhang

Pharmacy Faculty Articles and Research

Small-conductance Ca2+-activated K+ (SK) channels play essential roles in the regulation of cellular excitability and have been implicated in neurological and cardiovascular diseases through both animal model studies and human genetic association studies. Over the past two decades, positive modulators of SK channels such as NS309 and 1-EBIO have been developed. Our previous structural studies have identified the binding pocket of 1-EBIO and NS309 that is located at the interface between the channel and calmodulin. In this study, we took advantage of four compounds with potencies varying over three orders of magnitude, including 1-EBIO, NS309, SKS-11 (6-bromo-5-methyl-1H-indole-2,3-dione-3-oxime) and …

Prenatal Opioid Exposure And Intermittent Hypoxemia In Preterm Infants: A Retrospective Assessment, Elie G. Abu Jawdeh, Philip M. Westgate, Amrita Pant, Audra L. Stacy, Divya Mamilla, Aayush Gabrani, Abhijit R. Patwardhan, Henrietta S. Bada, Peter J. Giannone

Pediatrics Faculty Publications

Introduction: Intermittent hypoxemia (IH) is defined as episodic drops in oxygen saturation (SpO2). Preterm infants are at increased risk for IH due to their immature respiratory control/apnea of prematurity. The clinical relevance of IH is a relatively new observation with rising evidence linking IH to neonatal morbidities and long-term impairment. Hence, assessing factors that influence IH in preterm infants is imperative. Given the epidemic of opioid misuse in the USA, there is an urgent need to understand the impact of prenatal opioid exposure on neonatal outcomes. Hence, we wanted to assess the relationship between isolated prenatal opioid exposure …


Methylglyoxal Requires Ac1 And Trpa1 To Produce Pain And Spinal Neuron Activation, Ryan B. Griggs, Don E. Laird, Renee R. Donahue, Weisi Fu, Bradley K. Taylor Dec 2017

Methylglyoxal Requires Ac1 And Trpa1 To Produce Pain And Spinal Neuron Activation, Ryan B. Griggs, Don E. Laird, Renee R. Donahue, Weisi Fu, Bradley K. Taylor

Physiology Faculty Publications

Methylglyoxal (MG) is a metabolite of glucose that may contribute to peripheral neuropathy and pain in diabetic patients. MG increases intracellular calcium in sensory neurons and produces behavioral nociception via the cation channel transient receptor potential ankyrin 1 (TRPA1). However, rigorous characterization of an animal model of methylglyoxal-evoked pain is needed, including testing whether methylglyoxal promotes negative pain affect. Furthermore, it remains unknown whether methylglyoxal is sufficient to activate neurons in the spinal cord dorsal horn, whether this requires TRPA1, and if the calcium-sensitive adenylyl cyclase 1 isoform (AC1) contributes to MG-evoked pain. We administered intraplantar methylglyoxal and then evaluated …


A Novel Mutation In St14 At A Functionally Significant Amino Acid Residue Expands The Spectrum Of Ichthyosis-Hypotrichosis Syndrome., Leila Youssefian, Andrew Touati, Amir Hossein Saeidian, Omid Zargari, Sirous Zeinali, Hassan Vahidnezhad, Jouni Uitto Dec 2017

A Novel Mutation In St14 At A Functionally Significant Amino Acid Residue Expands The Spectrum Of Ichthyosis-Hypotrichosis Syndrome., Leila Youssefian, Andrew Touati, Amir Hossein Saeidian, Omid Zargari, Sirous Zeinali, Hassan Vahidnezhad, Jouni Uitto

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Mutations in the ST14 gene, encoding the serine protease matriptase, have been associated with ichthyosis-hypotrichosis syndrome (IHS), a Mendelian disorder with skin and hair manifestations which include, in addition to ichthyosis and hypotrichosis, hypohidrosis and follicular atrophoderma. However, the understanding of the specific consequences of mutations in ST14 on the development of this syndrome is incomplete.

RESULTS: Using a targeted next-generation sequencing array of 38 ichthyosis-associated genes on a large cohort of 180 ichthyosis patients from a primarily consanguineous background, a previously unreported homozygous p.Asp482Asn mutation in ST14 was identified in a patient with IHS. This mutation affects an …


The Climate Of Neurofeedback: Scientific Rigour And The Perils Of Ideology, Robert T. Thibault, Michael Lifshitz, Amir Raz Dec 2017

The Climate Of Neurofeedback: Scientific Rigour And The Perils Of Ideology, Robert T. Thibault, Michael Lifshitz, Amir Raz

Psychology Faculty Articles and Research

Over the last six decades, an in-group with ideological and financial stakes has been conducting sub-par research to develop an ostensibly effective clinical intervention: EEG-neurofeedback. More recently, however, a string of independent studies featuring increased scientific rigour and tighter experimental controls has challenged the foundation on which EEG-neurofeedback stands. Earlier this year, Brain published one of the most robust EEG-neurofeedback experiments to date (Schabus et al., 2017), which sparked a flurry of correspondence concerning the therapeutic value of neurofeedback (Fovet et al., 2017; Schabus, 2017); notably, a parallel discussion continues in Lancet Psychiatry …


A Biomechanical Study Examining The Subacromial Balloon Spacer And Superior Capsular Reconstruction In The Treatment Of Massive, Irreparable Rotator Cuff Tears, Supriya Singh Dec 2017

A Biomechanical Study Examining The Subacromial Balloon Spacer And Superior Capsular Reconstruction In The Treatment Of Massive, Irreparable Rotator Cuff Tears, Supriya Singh

Electronic Thesis and Dissertation Repository

Rotator cuff tears are common tendon injuries and can be a major source of pain and disability. Massive, irreparable rotator cuff tears are a challenging surgical dilemma as currently there is no gold standard treatment algorithm. Multiple possible treatment options exist yet no clear guidelines for optimal surgical technique for this disorder have been established.

In this study, two new techniques described in the treatment of massive, irreparable rotator cuff tears were explored; the insertion of a subacromial balloon spacer and superior capsular reconstruction. Their ability to restore glenohumeral joint kinematics was examined in cadaveric specimens with surgically created massive, …


Inhibitory Or Excitatory? Optogenetic Interrogation Of The Functional Roles Of Gabaergic Interneurons In Epileptogenesis, Hui Ye Dec 2017

Inhibitory Or Excitatory? Optogenetic Interrogation Of The Functional Roles Of Gabaergic Interneurons In Epileptogenesis, Hui Ye

Biology: Faculty Publications and Other Works

Alteration in the excitatory/inhibitory neuronal balance is believed to be the underlying mechanism of epileptogenesis. Based on this theory, GABAergic interneurons are regarded as the primary inhibitory neurons, whose failure of action permits hyperactivity in the epileptic circuitry. As a consequence, optogenetic excitation of GABAergic interneurons is widely used for seizure suppression. However, recent evidence argues for the context-dependent, possibly “excitatory” roles that GABAergic cells play in epileptic circuitry. We reviewed current optogenetic approaches that target the “inhibitory” roles of GABAergic interneurons for seizure control. We also reviewed interesting evidence that supports the “excitatory” roles of GABAergic interneurons in epileptogenesis. …


Optimal Management Of Post-Traumatic Radioulnar Synostosis, Arthur Lee Osterman, Melissa S. Arief Dec 2017

Optimal Management Of Post-Traumatic Radioulnar Synostosis, Arthur Lee Osterman, Melissa S. Arief

Department of Orthopaedic Surgery Faculty Papers

Post-traumatic radioulnar synostosis is a rare complication after forearm or elbow injury that can result in loss of motion and significant disability. Risk factors include aspects of the initial trauma and of the surgical treatment of that trauma. Surgical intervention for synostosis is the standard of care and is determined based on the location of the bony bridge. Surgical timing is recommended between 6 months and 2 years with recent advocacy for the 6- to 12-month period after radiographs demonstrate bony maturation but early enough to prevent further stiffness and contractures. For most types of synostosis, surgical resection with interposition …


Reorganization Of Thalamic Intrinsic Connectivity Following Anterior Temporal Lobectomy, Xiaosong He, Chaitanya Ganne, Michael R. Sperling, Ashwini Sharan, Joseph I. Tracy Dec 2017

Reorganization Of Thalamic Intrinsic Connectivity Following Anterior Temporal Lobectomy, Xiaosong He, Chaitanya Ganne, Michael R. Sperling, Ashwini Sharan, Joseph I. Tracy

Department of Neurosurgery Posters

The thalamus has played a crucial role in determining surgical outcome following anterior temporal lobectomy (ATL) in temporal lobe epilepsy (TLE) (He, et al., 2017). Before successfully quantifying the impact of the thalamus on ATL outcomes, this structure’s own intrinsic connectivity must be understood. Accordingly, we characterize thalamic intrinsic connectivity through resting-state fMRI (rsfMRI) longitudinally, exploring its change pre- to post-surgery.

Clinical and Translational Science Faculty Publications

Triggers of the autoimmune response that leads to type 1 diabetes (T1D) remain poorly understood. A possibility is that parallel changes in both T cells and target cells provoke autoimmune attack. We previously documented greater Ca2+ transients in fibroblasts from T1D subjects than non-T1D after exposure to fatty acids (FA) and tumor necrosis factor α (TNFα). These data indicate that metabolic and signal transduction defects present in T1D can be elicited ex vivo in isolated cells. Changes that precede T1D, including inflammation, may activate atypical responses in people that are genetically predisposed to T1D. To identify such cellular differences …
