Pulmonary Fibrosis As A Presentation Of Short Telomere Syndrome: Case Report, Roy Kondapavuluru, Jian Garcia Cruz, Sreejith Pillai, Andres Suarez Parraga

Research Colloquium

Introduction: Short telomere syndrome (STS), also known as accelerated aging syndrome, is an inheritable gene mutation resulting in decreased telomere length causing high cell turnover of organ systems such as skin, bone marrow, liver, hair, lungs, and immune system. Due to diverse clinical manifestations, STS poses a diagnostic challenge, with bone marrow failure and idiopathic pulmonary fibrosis being frequent manifestations. The inherited form of STS demonstrates genetic anticipation occurring at an earlier age with more severe manifestations in the affected progeny. We present a rare case of inherited STS in a young patient with severe pulmonary fibrosis.

Revolutionizing Feature Selection: A Breakthrough Approach For Enhanced Accuracy And Reduced Dimensions, With Implications For Early Medical Diagnostics, Shabia Shabir Khan, Majid Shafi Kawoosa, Bonny Bannerjee, Subhash C. Chauhan, Sheema Khan

Research Symposium

Background: The system's performance may be impacted by the high-dimensional feature dataset, attributed to redundant, non-informative, or irrelevant features, commonly referred to as noise. To mitigate inefficiency and suboptimal performance, our goal is to identify the optimal and minimal set of features capable of representing the entire dataset. Consequently, the Feature Selector (Fs) serves as an operator, transforming an m-dimensional feature set into an n-dimensional feature set. This process aims to generate a filtered dataset with reduced dimensions, enhancing the algorithm's efficiency.

Methods: This paper introduces an innovative feature selection approach utilizing a genetic algorithm with an ensemble crossover operation …

Multisystem Inflammatory Syndrome In Children (Mis-C): Is There A Relationship To Typhus?, Sravani Mannuru, Juliana Hager, Jacob Smith

Research Colloquium

The United Kingdom first reported in April 2020 a group of eight previously healthy children with a link to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that presented with systemic inflammation and multi-organ involvement, now named multisystem inflammatory syndrome in children (MIS-C). The Centers of Disease Control and Prevention (CDC) have reported over 1000 cases since the primary discovery as of October 2020 with 20 total deaths. [1] The clinical features of MIS-C have been previously compared to inflammatory syndromes including Kawasaki disease (KD) and toxic shock syndrome (TSS). We describe the clinical presentation and management for 3 pediatric cases with …

Hepatic Chylothorax, A Rare Finding In A Patient With Subacute Hepatic Hydrothorax, Oscar Rodrigo Zamudio Herrera, Shadi Jafari-Esfahani, Fatimah Bello

Research Colloquium

Background: The presence of chyle in the pleural space is termed chylothorax. Etiologies include traumatic (iatrogenic, blunt, or penetrating injury) and non-traumatic (non-malignant and malignant). Liver cirrhosis is a rare cause of non-traumatic, nonmalignant chylothorax. We describe a case of a transudative chylothorax in a patient with cirrhosis and hepatic hydrothorax.

E-Cigarette Or Vaping Use-Associated Lung Injury (Evali) In A Hispanic Male During The Covid-19 Pandemic, Juan C. Naranjo, Muhammad Jamal, Aramide Tijani, Fatimah Bello

Research Colloquium

Background: Electronic cigarette or vaping product use–associated lung injury established the relationship between vaping products and lung injury. Overlapping clinical manifestations may mimic those of other respiratory conditions including COVID-19. Multiple radiographic findings including diffuse, bilateral, ground-glass infiltrates with lower-lobe predominance, eosinophilic pneumonia, and diffuse alveolar damage have been described. It is important to consider this as an alternative diagnosis, particularly in patients with respiratory symptoms and a history of vaping in the last 90 days due to increased risk of COVID-19 infection and worse outcomes.

Case presentation: A 25-year-old male with a history of polysubstance abuse and frequent E-cigarette …

Clinical Characteristics And Risk Factors For Mortality During The 'First Wave' Of Covid-19 In Reynosa, Tamaulipas, Luis G. Vargas Garcia, Francisco E. Díaz Cisneros, Antonio Gutiérrez Sierra, Juan Rosales Martínez, Manlio F. Lara Duck, Netzahualcoyotl Mayek Pérez

Research Symposium

Background: The COVID-19 pandemic has impacted public health in Mexico. As of February 2020, there have been at least four "waves" of contagion that resulted in 5.82 million positive cases and more than 325 thousand deaths. At the beginning of the COVID-19 pandemic, hospital and population-based information was available, frequently with non-specific symptoms. Little was known about the risk factors for mortality in specific conditions. We described the clinical characteristics of patients with COVID-19 in Reynosa, Tamaulipas during 2020 and identified the risk factors for mortality.

Methods: The COVID-19 cases registered from March to November 2020 in Reynosa were divided …

Acute Eosinophilic Pneumonia In A Patient With Long Standing Behcet’S Syndrome, Juan C. Naranjo, Shadi J. Estefahani, Christine E. Loftis, Emilia Dulgheru

Research Symposium

Background: Behcet’s syndrome (BS) is a multisystemic disease that frequently manifests as oral and genital ulcers. Pulmonary involvement occurs in approximately 18% of patients and can have complex clinical manifestations, including vascular disease, hemorrhage, infarctions, and organizing pneumonia. Broad-spectrum radiological findings like loss of lung volume, lung opacities, and indistinct nodular or reticular lesions have been described. There is little data on the association between Behcet’s disease and eosinophilic pneumonitis; the latest is usually characterized by eosinophilic infiltration of the lung parenchyma caused by a hypersensitivity reaction to an inhaled antigen. Patients usually present with nonproductive cough, dyspnea, fever, and …

A Case Report Of A Primary Cerebral Abscess Due To Nocardia Asteroides In An Immunocompetent Patient, Ileana Elita Mendez, Nicole Marie Barreto, Alan Lanurias, Luis Alberto Rosas

Research Symposium

Background: Brain abscesses caused by Nocardia are rarely reported and have high mortality. It usually affects patients who are immunocompromised and initiates as a lung infection that disseminates hematogenously, though it can also affect those immunocompetent. Cerebral nocardiosis imitates brain tumors, which can delay the initiation of the appropriate antibiotic therapy.

Case Description: We present a case of a 64-year-old immunocompetent male with multiple cerebral abscesses who presented with headaches, left-sided weakness, and ataxia. Upon imaging, multiple brain lesions were revealed. The patient underwent craniotomy and drainage of the mass. He was initially empirically treated, though cultures later grew Nocardia …

End Tidal Carbon Dioxide Monitoring (Capnography) In The Cardiac Intensive Care Unit, Madeline Elaine Huff, Kenneth T. Shelton

School of Medicine Publications

Background: Carbon dioxide levels can be monitored throughout the respiratory cycle via capnography. In this way, capnography allows healthcare professionals to follow several respiratory factors in real-time, including respiratory depression, apnea, and hypercapnia. Postoperative patients are subjected to significant harm while receiving sedating medications without appropriate monitoring and intervention. Earlier detection of alterations to ventilation status will better enable providers to more accurately dose medications during procedures, especially in high-risk patient populations.

Methods: Patient selection included post-operative patients in the intensive care unit that were receiving sedation/analgesia, high dose or high frequency opioids, epidural or intrathecal pain management, patients that …
