Sarcoidosis With Isolated Osseous Manifestations Mimicking Metastatic Malignancy, Ahmed Ismail, Ahmed Saleh, Yanis Boumber

Department of Medicine Faculty Publications

Sarcoidosis is an inflammatory disease of unknown etiology that commonly involves multiple organ systems, with the lungs and lymph nodes most frequently affected. Osseous involvement, although recognized, is considered uncommon and often overlooked due to its nonspecific clinical and radiographic features. Patients may be asymptomatic or present with pain, swelling, and functional limitations of the affected limb. Imaging can reveal findings such as bone lesions that mimic malignancy, including lytic or sclerotic changes. Diagnosis relies on histopathological confirmation of non-caseating granulomas. Treatment is directed at symptom relief and preservation of limb function. Here, we present a rare case of isolated …

Ribosome Hibernation In Mycobacterium Abscessus And Its Effect On Antibiotic Resistance, Ryan Treen

Electronic Theses & Dissertations (2024 - present)

Non-tuberculosis mycobacteria (NTM) represent a diverse repertoire of species, most of which are ubiquitous in the environment. Some NTM species, such as Mycobacterium abscessus, can cause life-threatening infections in people with underlying medical conditions. The clinical incidence of such infections is on the rise, posing an emerging threat to public health. M. abscessus is characterized by intrinsic and acquired antibiotic resistance, complicating treatment strategies. Most chemotherapeutic approaches for M. abscessus infection target the bacterial ribosome, necessitating a better understanding of the physiological processes which confer this resistance. Multiple mycobacterial species respond to zinc-limiting conditions by inducing remodeling and hibernation …

The Complex Relationship Between Tuberculosis And Hyperglycemia, Michelle Byers, Elizabeth Guy

Faculty, Staff and Students Publications

Hyperglycemia and tuberculosis are dual global pandemics. Each has a propulsive and amplifying effect on the other, and, because of this, we must consider hyperglycemia and tuberculosis together. Hyperglycemia is immunosuppressive and increases the risk of tuberculosis by threefold. It also leads to a more advanced presentation of pulmonary tuberculosis, thus increasing the likelihood of being smear positive and having cavitating lesions, and it impacts the duration and outcomes of treatment, with an increased one year mortality seen in patients with tuberculosis and diabetes. Additionally, any degree of hyperglycemia can have an impact on susceptibility to tuberculosis, and this effect …

Α4 Nicotinic Acetylcholine Receptors In Lipopolysaccharide-Related Lung Inflammation, J. Ritzenthaler, Walter H. Watson, Jesse Roman

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Sepsis remains an important healthcare challenge. The lungs are often affected in sepsis, resulting in acute lung injury characterized by inflammation. Mechanisms involving lipopolysaccharide (LPS) stimulation of toll-like receptor (TLR) signaling with induction of proinflammatory pathways have been implicated in this process. To date, however, studies targeting these pathways have failed to improve outcomes. We have found that LPS may also promote lung injury through the activation of α4 nicotinic acetylcholine receptors (α4 nAChRs) in immune cells. We observed increased expression of α4 nAChRs in human THP-1 monocytic cells exposed to LPS (100 ng/mL, 24 h). We also observed that …

Lung Cancer remains the leading cause of cancer deaths in the USA and worldwide. Non-small cell lung cancer (NSCLC) harbors high transcriptomic intratumor heterogeneity (RNA-ITH) that limits the reproducibility of expression-based prognostic models. In this study, we used multiregional RNA-seq data (880 tumor samples from 350 individuals) from both public (TRACERx) and internal (MDAMPLC) cohorts to investigate the effect of RNA-ITH on prognosis in localized NSCLC at the gene, signature, and tumor microenvironment levels. At the gene level, the maximal expression of hazardous genes (expression negatively associated with survival) but the minimal expression of protective genes (expression positively associated with …

Lung cancer remains the leading cause of cancer mortality, despite declining smoking rates. Previous lung cancer GWAS have identified numerous loci, but separating the genetic risks of lung cancer and smoking behavioral susceptibility remains challenging. Here, we perform multi-ancestry GWAS meta-analyses of lung cancer using the Million Veteran Program cohort (approximately 95% male cases) and a previous study of European-ancestry individuals, jointly comprising 42,102 cases and 181,270 controls, followed by replication in an independent cohort of 19,404 cases and 17,378 controls. We then carry out conditional meta-analyses on cigarettes per day and identify two novel, replicated loci, including the 19p13.11 …

Forecasting The Effects Of Smoking Prevalence Scenarios On Years Of Life Lost And Life Expectancy From 2022 To 2050: A Systematic Analysis For The Global Burden Of Disease Study 2021, Gbd 2021 Tobacco Forecasting Collaborators

Ateneo School of Government Publications

Background

Smoking is the leading behavioural risk factor for mortality globally, accounting for more than 175 million deaths and nearly 4·30 billion years of life lost (YLLs) from 1990 to 2021. The pace of decline in smoking prevalence has slowed in recent years for many countries, and although strategies have recently been proposed to achieve tobacco-free generations, none have been implemented to date. Assessing what could happen if current trends in smoking prevalence persist, and what could happen if additional smoking prevalence reductions occur, is important for communicating the effect of potential smoking policies.

Methods

In this analysis, we use …

Effects Of Educational Intervention On Asthmatic Children, Zoe Coggins

Nursing | Student Research Posters

Abstract

Children are more vulnerable to asthmatic symptoms due to the physiological immaturity of their respiratory systems. Therefore, irritants are deemed more hazardous for the pediatric population. Pollution is a growing health concern, and within the literature review, several approaches to the measurement of the impact of low air quality and educational interventions are discussed. The themes identified in the literature review are increased risk of pollution-induced exacerbation due to age, behavior, and residential proximity to emission-producing facilities. The review of the literature demonstrated how pollution is a growing public health concern, especially among the pediatric population. Interventions, reviewed in …

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.
