Background: Colorectal cancer is the third most deadly cancer among African Americans (AA). When compared to Caucasian Americans (CA), AA present with more advanced disease and lower survival rates. Here, we investigated if differences in tumor immunology could be contributive to disparities observed between these populations. Methods: We examined gene expression of tumor and non-tumor adjacent tissues from AA and CA by whole transcriptome sequencing, and generated scores for immune cell populations by NanoString. In addition, we utilized “The Cancer Genome Atlas” (TCGA) database from AA and CA as a validation cohort. Finally, we measured the secretion of cytokines characteristic …

Anaesthesiology, East Africa

Background: In low- and middle-income countries (LMICs) where echocardiography experts are in short supply, training non-cardiologists to perform Focused Cardiac Ultrasound (FoCUS) could minimise diagnostic delays in time-critical emergencies. Despite advocacy for FoCUS training however, opportunities in LMICs are limited, and the impact of existing curricula uncertain. The aim of this study was to assess the impact of FoCUS training based on the Focus Assessed Transthoracic Echocardiography (FATE) curriculum. Our primary objective was to assess knowledge gain. Secondary objectives were to evaluate novice FoCUS image quality, assess inter-rater agreement between expert and novice FoCUS and identify barriers to the establishment …

TGF-β is a master regulator of fibrosis, driving the differentiation of fibroblasts into apoptosis-resistant myofibroblasts and sustaining the production of extracellular matrix (ECM) components. Here, we identified the nuclear long noncoding RNA (lncRNA) H19X as a master regulator of TGF-β-driven tissue fibrosis. H19X was consistently upregulated in a wide variety of human fibrotic tissues and diseases and was strongly induced by TGF-β, particularly in fibroblasts and fibroblast-related cells. Functional experiments following H19X silencing revealed that H19X was an obligatory factor for TGF-β-induced ECM synthesis as well as differentiation and survival of ECM-producing myofibroblasts. We showed that H19X regulates DDIT4L gene …

Inadvertent Stone Migration During Pneumatic Lithotripsy: Still A Conundrum In The 21st Century, Ali Akbar Zehri, Miten Patel, Philip Adebayo, Authar Ali

General Surgery, East Africa

Currently, an ideal gadget to stop retrograde stone migration remains a holy grail, and the hunt for such a device is still ongoing in the 21st century. The quest for an ideal instrument is driven by the need to reduce cost, minimize ancillary procedure rates, reduce the device's operative time, and improve the stone-free rate. The purpose of the present review is to provide an update on the use of preventive measures that are used to stop retrograde stone migration during pneumatic lithotripsy for ureteric stone management.

Postinfectious Cerebellar Syndrome With Paraneoplastic Antibodies: An Association Or Coincidence?, Sajid Hameed, Mukesh Kumar, Pal Satyajit Singh Athwal, Sukhmanii Kahlon, Nimit Dalal

Section of Neurology

Cerebellar ataxia has a very broad differential diagnosis in adults, including paraneoplastic and postinfectious etiologies. We report a case of a 56-year-old male presented with right-sided cerebellar dysfunction preceded by fever and headache. He was diagnosed with subacute postinfectious cerebellar ataxia. Blood serology showed the presence of anti-amphiphysin and anti-Ri (ANNA-2, antineuronal nuclear autoantibody type 2) antibodies, which have a known association with cerebellar syndrome. The patient subsequently improved with the steroids. Although no evidence of an underlying tumor was found in the patient, the presence of the paraneoplastic antibodies remains a mystery. We suggest a probable association of these …

Although extracorporeal membrane oxygenation (ECMO) has been used in many different populations, its use in pregnant or postpartum patients has not been widely studied. This article reviews the ECMO experience in this population at a large urban hospital. Electronic medical records for all pregnant or postpartum patients who required ECMO between 2012 and 2019 were retrospectively reviewed. Data on clinical characteristics, outcomes, and complications were gathered. Comparisons between survivors and nonsurvivors were completed. Ten postpartum patients were identified. The patients presented as follows: four with cardiac arrest, one with a massive pulmonary embolism, three with acute respiratory distress syndrome (ARDS), …

Loss Of Uncoupling Protein 3 Attenuates Western Diet-Induced Obesity, Systemic Inflammation, And Insulin Resistance In Rats, Tyler M Lomax, Sadia Ashraf, Gizem Yilmaz, Romain Harmancey

Faculty, Staff and Student Publications

OBJECTIVE: Uncoupling protein 3 (UCP3) is a mitochondrial carrier related to fatty acid metabolism. Although gene variants of UCP3 are associated with human obesity, their contribution to increased adiposity remains unclear. This study investigated the impact that loss of UCP3 has on diet-induced obesity in rats.

METHODS: Male UCP3 knockout rats (ucp3

RESULTS: Loss of UCP3 decreased fat mass gain, white adipocytes size, and systemic inflammation. The ucp3

CONCLUSIONS: Loss of UCP3 partially protects rats from diet-induced obesity. This phenotype is related to induction of a compensatory antioxidant mechanism and prevention of iBAT whitening.

Flash Pulmonary Edema: A Case And Review Of Left Ventricular Non-Compaction Cardiomyopathy, Paula J. Watts, Oliver S. Garbo, Wendy Barrett, Michael Kopstein, Ryan Maybrook, Dmitriy Scherbak

HCA Healthcare Journal of Medicine

Left ventricular non-compaction cardiomyopathy is an uncommon type of cardiomyopathy caused by malformation of the myocardium during embryogenesis. This results in trabeculations within the ventricular wall that can affect the left and, less commonly, right ventricles. Presentation ranges from clinically asymptomatic to life-threatening arrhythmias. It is a rare and relatively unknown form of cardiomyopathy, though thought to be underdiagnosed. Prevalence is increasing due to improvements in imaging and awareness. Management is similar to that of other cardiomyopathies including angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers, beta-blockers, diuretics, automatic implantable cardioverter defibrillator placement and cardiac transplantation. We present a case of a …

Novel Use Of Fresh Frozen Plasma In Treating Hereditary Angioedema: A Success Story From Pakistan, Amber Sabeen Ahmed, Sidra Fayyaz

Section of Internal Medicine

Hereditary angioedema (HAE) due to a C1-esterase inhibitor(C1-INH) deficiency is a rare and potentially life-threatening disorder. It is characterized by an episodic and self-limiting increase in vascular permeability. The condition manifests itself as recurrent attacks of swelling in any part of the body. The angioedema can cause the involvement of the respiratory tract, skin, and gastrointestinal tract. Laryngeal involvement can make the condition life-threatening. It does not respond well to conventional angioedema therapy of steroids, adrenaline, and antihistamines. The targeted therapy for HAE consists of plasma-derived or recombinant C1-INH, ecallantide, and icatibant or bradykinin receptor antagonist. In the absence of …
