Whole-brain volumetric microscopy techniques such as serial two-photon tomography (STPT) can provide detailed information on the roles of neuroinflammation and neuroplasticity throughout the whole brain post-stroke. STPT automatically generates high-resolution images of coronal sections of the entire mouse brain that can be readily visualized in three dimensions. We developed a pipeline for whole brain image analysis that includes supervised machine learning (pixel-wise random forest models via the “ilastik” software package) followed by registration to a standardized 3-D atlas of the adult mouse brain (Common Coordinate Framework v3.0; Allen Institute for Brain Science). These procedures allow the detection of cellular fluorescent …

Validation Of A Miniaturized Permeability Assay Compatible With Crispr-Mediated Genome-Wide Screen., Claire Simonneau, Junning Yang, Xianguo Kong, Robert Kilker, Leonard Edelstein, Paolo Fortina, Eric R. Londin, Arie Horowitz

Cardeza Foundation for Hematologic Research

The impermeability of the luminal endothelial cell monolayer is crucial for the normal performance of the vascular and lymphatic systems. A key to this function is the integrity of the monolayer's intercellular junctions. The known repertoire of junction-regulating genes is incomplete. Current permeability assays are incompatible with high-throughput genome-wide screens that could identify these genes. To overcome these limitations, we designed a new permeability assay that consists of cell monolayers grown on ~150 μm microcarriers (MCs). Each MC functions as a miniature individual assay of permeability (MAP). We demonstrate that false-positive results can be minimized, and that MAP sensitivity to …


Developing A Local Anesthetic Systemic Toxicity Protocol In A Mississippi Hospital, James Dearman, Terry J. Tieman Oct 2019

Developing A Local Anesthetic Systemic Toxicity Protocol In A Mississippi Hospital, James Dearman, Terry J. Tieman

Doctoral Projects

Local anesthetic systemic toxicity (LAST) is a rare complication of administering local anesthetic medications. However, this complication is potentially deadly, especially without prompt and correct treatment. Due to the rarity of LAST and the fact that its treatment differs from the conventional treatment of cardiac arrest, the authors sought a best practice recommendation to guide its treatment. While the most effective treatment for LAST has been well established, a thorough review of literature and survey of clinical preceptors demonstrated that most providers have not encountered LAST in clinical practice. Additionally, lipid emulsion therapy is a somewhat controversial treatment among some …

Molecular Characterization Of Multidrug-Resistance In Gram-Negative Bacteria From The Peshawar Teaching Hospital, Pakistan, A. Masseron, L. Poirel, B. Jamil Ali, M. A. Syed, P. Nordmann

Section of Pulmonary & Critical Care

Extended-spectrum β-lactamases, carbapenemases, 16S rRNA methylases conferring pan-drug aminoglycoside resistance and colistin resistance were investigated among Gram-negative bacteria recovered from clinical samples (infections) from 200 individuals hospitalized at the Khyber Teaching Hospital of Peshawar, north Pakistan, from December 2017 to March 2018. Out of 65 isolates recovered, 19% were carbapenem resistant and 16% carried a bla NDM-1 gene, confirming the widespread distribution of NDM producers in this country. The association of the NDM carbapenem-resistance determinant, together with the extended-spectrum β-lactamase CTX-M-15 and 16S rRNA methylases, was frequent, explaining the multidrug-resistance pattern observed. All isolates remained susceptible to colistin.

Obstetrics and Gynaecology, East Africa

Background: Expired carbon dioxide (ECO2) indicates degree of lung aeration immediately after birth. Favourable ventilation techniques may be associated with higher ECO2 and a faster increase. Clinical condition will however also affect measured values. The aim of this study was to explore the relative impact of ventilation factors and clinical factors on ECO2 during bag-mask ventilation of near-term newborns.

Methods: Observational study performed in a Tanzanian rural hospital. Side-stream measures of ECO2, ventilation data, heart rate and clinical information were recorded in 434 bag-mask ventilated newborns with initial heart rate <120 beats per minute. We studied ECO2 by clinical factors (birth weight, Apgar scores and initial heart rate) and ventilation factors (expired tidal volume, ventilation frequency, mask leak and inflation pressure) in random intercept models and Cox regression for time to ECO2 >2%.

Results: ECO2 rose non-linearly with increasing expired tidal volume …


Hemostatic Complications Associated With Ventricular Assist Devices., Talal Hilal, James O Mudd, Thomas G Deloughery Oct 2019

Hemostatic Complications Associated With Ventricular Assist Devices., Talal Hilal, James O Mudd, Thomas G Deloughery

Articles, Abstracts, and Reports

Hemostatic complications are common in patients with ventricular assist devices. The pathophysiologic mechanisms that lead to dysregulated hemostasis involve complex interactions between device surface, sheer stress, and blood flow. These factors lead to various manifestations that require a thorough understanding of the interplay among platelets, coagulation factors, and red cells. In this article, we review the pathophysiology of hematologic complications (bleeding, acquired von Willebrand disease, heparin-induced thrombocytopenia, hemolysis, stroke and pump thrombosis), the clinical manifestations, and the management of each. We summarize the evidence available for management of these entities and provide a pragmatic clinical review.

Evidence-Based Best Practice Policy Recommendation For Postoperative Sore Throat, Corey Gambrell Oct 2019

Evidence-Based Best Practice Policy Recommendation For Postoperative Sore Throat, Corey Gambrell

Doctoral Projects

Airway management is a fundamental aspect of patient care when general anesthesia is being administered. Unfortunately, tracheal intubation can lead to the development of postoperative sore throat (POST) in the recovery room. POST is a minor yet preventable consequence of manipulation and injury of the airway mucosa. POST is routinely considered a minor postoperative complication; however, the occurrence of POST can have a negative influence on patient satisfaction as well as their perception of the perioperative experience. The etiology of POST is multifactorial, but evidence indicates that prevention is possible when evidenced-based practices are employed by anesthesia providers. A targeted …

La Ciudad Versus El Campo: La Calidad De Vida De Los Adultos Mayores Aymara Entre Arica Y Putre, Clare Rogowski

Independent Study Project (ISP) Collection

The elderly population in Chile is increasing rapidly. In indigenous villages in the interior of Chile, like Putre, the younger generation is leaving to pursue education and employment opportunities in cities, in this case Arica. In many cases no one stays to take care of the elders. As the elderly begin to grow older and require greater support, the younger generation seeks to move their family members to the city so that they can care for them. While this provides for greater connection to family and access to medical care for the elderly relatives, the elderly loses their connection to …

Internal Medicine, East Africa

The association between obstructive sleep apnea (OSA) and attention deficit hyperactivity disorder (ADHD) is well-established in children. However, there is a paucity of literature regarding this association in adults. The aim of this study was to determine if ADHD is more common in adult patients with OSA. All patients referred to a sleep center for sleep evaluation were administered the Adult ADHD Self-Report Scale and diagnostic polysomnogram. The ADHD screen is considered positive if 4 of 6 questions in part A of the screening questionnaire were answered abnormally. The study population consisted of 194 participants, predominantly male (62%), Caucasian (54%), …


Hyperbaric Oxygen Therapy: Effect On Wound Healing And Traumatic Brain Injuries, Sara L. Seuffert Oct 2019

Hyperbaric Oxygen Therapy: Effect On Wound Healing And Traumatic Brain Injuries, Sara L. Seuffert

Student Publications

Hyperbaric Oxygen Therapy is a new form of treatment being used to heal and help improve symptoms of traumatic brain injuries, external wounds, and strokes. HBOT helps to completely saturate hemoglobin with oxygen, which then allows for a larger capacity of oxygen to be delivered to the damaged tissues. Tissue wounds benefit from this HBOT because of the increase in oxygen supply to the damaged area, helping to combat hypoxia, which is preventing proper wound healing. The increase in oxygen allows for an increase in myofibroblast differentiation to allow the healing process to continue. HBOT has also proven to increase …

Oral Delivery Of Xenon For Cardiovascular Protection, Xing Yin, Melanie R Moody, Valeria Hebert, Melvin E Klegerman, Yong-Jian Geng, Tammy R Dugas, David D Mcpherson, Hyunggun Kim, Shao-Ling Huang

Faculty, Staff and Student Publications

Cardiac hypertrophy often causes impairment of cardiac function. Xenon (Xe), a naturally occurring noble gas, is known to provide neurological and myocardial protection without side effects. The conventional method of Xe delivery by inhalation is not feasible on a chronic basis. We have developed an orally deliverable, effective Xe formulation for long-term administration. We employed 2-hydroxypropyl)-β-cyclodextrin (HPCD), which was dissolved in water to increase the Xe concentration in solution. The beneficial effects of long-term oral administration of Xe-enriched solutions on cardiovascular function were evaluated in vivo. HPCD increased Xe solubility from 0.22 mM to 0.67 mM (3.8-fold). Aged ApoE knockout …

Frequency And Early Complications Of Late Preterm Infants: A Descriptive Analysis From Two Secondary-Care Hospitals Of Karachi, Waqar Khowaja, Abdul Lateef Leghari, Ali Shabbir Hussain, Shabina Ariff, Iqtidar Khan

Department of Paediatrics and Child Health

Introduction: Globally, prematurity accounts for 12.7% of all live births while late preterm accounts for around three-fourth (73%) of these premature births. In Pakistan, the prevalence of prematurity is approximately 18.89%. Late preterm infants often have weight and size similar to some term infants, but they are still metabolically and physiologically immature. Hence, these infants, as compared to term infants, are at a higher risk of developing medical complications, which results in higher morbidity and mortality during the birth hospitalization. We aim to determine the frequency of early complications in late preterm infants during their stay at Aga Khan Secondary-care …

Systemic metabolic alterations associated with increased consumption of saturated fat and obesity are linked with increased risk of prostate cancer progression and mortality, but the molecular underpinnings of this association are poorly understood. Here, we demonstrate in a murine prostate cancer model, that high-fat diet (HFD) enhances the MYC transcriptional program through metabolic alterations that favour histone H4K20 hypomethylation at the promoter regions of MYC regulated genes, leading to increased cellular proliferation and tumour burden. Saturated fat intake (SFI) is also associated with an enhanced MYC transcriptional signature in prostate cancer patients. The SFI-induced MYC signature independently predicts prostate cancer …

Given that colon cancer is the third most common cancer in incidence and cause of death in the United States, and current treatment modalities are insufficient, there is a need to develop novel agents. Towards this, here we focus on γ-Mangostin, a bioactive compound present in the Mangosteen (Garcinia mangostana) fruit. γ-Mangostin suppressed proliferation and colony formation, and induced cell cycle arrest and apoptosis of colon cancer cell lines. Further, γ-Mangostin inhibited colonosphere formation. Molecular docking and CETSA (Cellular thermal shift assay) binding assays demonstrated that γ-Mangostin interacts with transcription factor TCF4 (T-Cell Factor 4) at the β-catenin …

Bayesmetab: Treatment Of Missing Values In Metabolomic Studies Using A Bayesian Modeling Approach, Jasmit Shah, Guy N. Brock, Jeremy Gaskins

Internal Medicine, East Africa

Background: With the rise of metabolomics, the development of methods to address analytical challenges in the analysis of metabolomics data is of great importance. Missing values (MVs) are pervasive, yet the treatment of MVs can have a substantial impact on downstream statistical analyses. The MVs problem in metabolomics is quite challenging and can arise because the metabolite is not biologically present in the sample, or is present in the sample but at a concentration below the lower limit of detection (LOD), or is present in the sample but undetected due to technical issues related to sample pre-processing steps. The …
