Advancing Trypanosoma Cruzi N-Myristoyltransferase As A Drug Target For Chagas Disease Through In Silico Discovery And Biochemical Evaluation, Diana Citlali González García
Advancing Trypanosoma Cruzi N-Myristoyltransferase As A Drug Target For Chagas Disease Through In Silico Discovery And Biochemical Evaluation, Diana Citlali González García
Open Access Theses & Dissertations
Chagas disease remains one of the most persistent and neglected parasitic infections in the Americas, advancing silently through the intracellular replication of Trypanosoma cruzi amastigotes and the invasive spread of trypomastigotes. The survival of the parasite is critically reliant on protein N-myristoylation, a lipid modification catalyzed by N-myristoyltransferase (NMT). This dissertation aims to advance beyond prior studies by systematically investigating NMT inhibition across multiple biological levels, spanning from the characterization of the purified enzyme, through cellular infection models, to the global proteomic remodeling induced within the parasite, thereby evaluating TcNMT as a potential therapeutic vulnerability in T.cruzi.Recombinant TcNMT was expressed, …

Background: Neuro-oncology education in American neurology departments is highly variable, with no clear guidelines on appropriate practices. To better understand its current state, we focus on the perspective of departmental Grand Rounds (GR), views of adult neurology residency program directors (ANRPD), neuro-oncologists, and residents.
Methods: First, we obtained GR series from academic years 2017-2018 and 2018-2019 via an online search and direct emails to neurology residency programs. Second, two online surveys were dispensed to ANRPD and neuro-oncologists. Third, a cohort of neurology residents completed surveys with pre/post-didactic tests.
Results: Neuro-oncology consisted of 7% (28/ 411) GR in 2017-2018 and 6% …

Cancerous tissue is a largely unexplored microbial niche that provides a unique environment for the colonization and growth of specific bacterial communities, and with it, the opportunity to identify novel bacterial species. Here, we report distinct features of a novel Fusobacterium species, F. sphaericum sp. nov. (Fs), isolated from primary colon adenocarcinoma tissue. We acquire the complete closed genome and associated methylome of this organism and phylogenetically confirm its classification into the Fusobacterium genus, with F. perfoetens as its closest neighbor. Fs is phenotypically and genetically distinct, with morphological analysis revealing its coccoid shape, that while similar to …

Whipple disease is a rare systemic disease caused by Tropheryma whipplei. It can present with a wide range of nonspecific symptoms that might overlap with underlying medical conditions, posing a diagnostic challenge. We present a 61-year-old man with a past medical history of rheumatoid arthritis and chronic inflammatory demyelinating polyneuropathy, who presented with persistent leukocytosis and supraclavicular lymphadenopathy. A positron emission tomography scan revealed hypermetabolic activity in the supraclavicular, abdominal, and pelvic lymph nodes along with a myocardial hypermetabolic lesion, concerning a lymphoproliferative disorder versus sarcoidosis. A supraclavicular lymph node excisional biopsy revealed complete architectural effacement by a diffuse foamy …

Background: Malaria continues to be a major public health challenge in Sub-Saharan Africa (SSA), where the majority of the countries have not met the World Health Assembly's endorsed Global Technical Strategy (GTS) milestones in 2020 for malaria reduction. Insecticide-treated net (ITN) usage is a well-established and effective intervention, often outperforming other measures such as indoor residual spraying (IRS). However, multiple survey studies have reported improper use of ITNs across various SSA countries. This misuse likely poses an important barrier to the intervention's success, although it remains a largely untested hypothesis.
Methods: We developed a behaviour-incidence model and statistical analysis of …

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare complication of solid organ transplantation and is a syndrome of systemic hyperinflammation secondary to dysregulation of the inflammatory response, primarily involving lymphocytes and macrophages. It is often fatal and therefore early recognition and treatment are crucial. Among 11 adult cases of HLH in post-lung transplant cases found in the literature, only one patient survived.
Case: We report the first known pediatric case of HLH following lung transplantation. The patient, a previously healthy adolescent, developed end-stage bullous lung disease secondary to acute respiratory distress syndrome (ARDS) and underwent bilateral lung transplantation. Two months posttransplant, …

Dermatologic infections, particularly fungal and viral, are globally prevalent and often lead patients to seek complementary and alternative medicines (CAMs). This review critically evaluates 17 studies investigating CAM efficacy in treating dermatologic infectious diseases, focusing on those evaluated in randomized controlled trials (RCTs). Tea tree oil shows modest benefit for fungal infections such as tinea pedis and onychomycosis, though studies are limited by poor blinding and dropout rates. For herpes simplex virus (HSV), propolis and Melissa officinalis demonstrate potential antiviral effects, but findings are limited by subjective outcomes and industry sponsorship. Green tea extract (polyphenon E) shows efficacy in treating …

Background: Tuberculosis (TB) remains a leading cause of morbidity and mortality worldwide. Individuals with type 2 diabetes (T2D) are at increased risk of developing active TB, tend to present with more severe disease and experience adverse treatment outcomes compared to individuals without T2D co-morbidity. However, the underlying mechanisms responsible for increased susceptibility of patients with T2D to TB remain poorly understood.
Methods: We performed bronchoscopies and collected bronchoalveolar lavage fluid (BAL) from TB contacts with and without T2D in South Africa and obtained paired human alveolar macrophages (HAMs) and monocyte-derived macrophages (MDMs) for transcriptomic, epigenetic and functional assays.
Findings: Following …

House screening (HS) of doors, eaves, and windows using wire-mesh has demonstrated potential in the integrated vector management of malaria. However, limited epidemiological data are available to guide its implementation across different ecological settings. In a 16-month randomized controlled trial (follow-up period) conducted across three agroecological areas (dry mountain, plateau highland, and semi-arid) in Jabi Tehnan district, northwestern Ethiopia, treatment houses were equipped with HS combined with insecticide-treated nets (ITNs), while control houses received ITNs only. The intervention led to a significant 2.3-fold reduction in indoor malaria vector density, the primary entomologic outcome, largely influenced by An. gambiae s.l. mosquitoes. …

Background: Despite significant global effort to control and eradicate malaria, many cases and deaths are still reported yearly. These efforts are hindered by several factors, including the severe underestimation of cases and deaths, especially in Africa. Methods: We used a mathematical model, incorporating the underestimation of cases and seasonality in mosquito biting rate, to study the malaria dynamics in Cameroon. Using a Bayesian inference framework, we calibrated our model to the monthly reported malaria cases in ten regions of Cameroon from 2019 to 2021 to quantify the underestimation of cases and estimate other important epidemiological parameters. We performed Hierarchical Clustering …

Public Health Trade-Offs During A Pandemic: Mobility Decline And Hypertension Risk In India, Arpita Khanna, Tomoki Fujii
Research Collection School Of Economics
The Covid pandemic dramatically altered patterns of daily life, particularly through widespread declines in mobility due to lockdowns and social distancing measures. While the economic and epidemiological effects of these restrictions have been widely studied, their broader health implications remain underexplored. This paper investigates the relationship between mobility decline during the Covid pandemic and hypertension outcomes in India. Leveraging district-level variation in mobility from Google Community Mobility Reports and health data from the 2019–2021 Indian Demographic and Health Survey (DHS), we find that a 1 percentage point reduction in mobility over the 30 days prior to interview is associated with …

BACKGROUND: Human adenovirus (HAdV) is a common cause of pediatric acute respiratory illness (ARI), contributing to 5-13% of cases worldwide. Clinical manifestations vary by HAdV species and type; therefore, delineating type-specific disease presentations and understanding severity of specific HAdV types' disease may help develop targeted interventions.
METHODS: We conducted a multicenter, prospective study within the New Vaccine Surveillance Network to characterize HAdV types. Children < 18 years old with ARI were enrolled in the emergency department or inpatient setting at 7 US children's hospitals from 1 December 2016 to 30 November 2019. Respiratory specimens were collected and tested for HAdV and other viruses. Subsequently, typing was conducted on HAdV specimens using single-plex real-time PCR assays targeting sequences in the hexon gene. Comparisons between HAdV types were performed to determine differences in characteristics and outcomes. Generalized linear mixed effects models were used to evaluate severity.
RESULTS: Among the 1843 HAdV-positive cases, 1402 specimens (76%) were typed. The most common types detected were HAdV-C1 (n = 439), HAdV-C2 (n = 393), and HAdV-B3 (n = 221). Children with HAdV-B7 (n = 78) …

Hyperuricemia (HUA) and gout result from imbalances in uric acid metabolism and are closely associated with the gut microbiota. Advanced analytical methods facilitate the exploration of microbiota complexity. In this study, 16S rRNA sequencing data from stool samples of 233 patients were thoroughly collected. Machine learning (ML) and Shapley Additive exPlanations (SHAP) interpretability algorithms were applied to identify core taxa and predict the metabolic functions. The results revealed that the high-contribution core taxa identified by SHAP in each group, such as Oscillospiraceae_UCG-005 and Rhodococcus provided the basis for ML prediction. Among the five classification models, Random Forest (RF) achieved the …

An increasing number of patients are living with cardiac implantable electronic devices (CIEDs). When a patient with a CIED is hospitalized with concern for infection or positive blood cultures from any source, recognizing and managing a possible CIED infection is critical due to its significant morbidity and mortality risk. Internists are often the first to evaluate these patients and must consider the possibility of an underlying device infection. Gram-positive bacteremia carries a high risk of CIED infection, often necessitating cardiac imaging. In contrast, hematogenous seeding with gram-negative bacteremia is infrequent.

Background: Human adenovirus (HAdV) is a common cause of pediatric acute respiratory illness (ARI), contributing to 5-13% of cases worldwide. Clinical manifestations vary by HAdV species and type; therefore, delineating type-specific disease presentations and understanding severity of specific HAdV types' disease may help develop targeted interventions.
Methods: We conducted a multicenter, prospective study within the New Vaccine Surveillance Network to characterize HAdV types. Children < 18 years old with ARI were enrolled in the emergency department or inpatient setting at 7 US children's hospitals from 1 December 2016 to 30 November 2019. Respiratory specimens were collected and tested for HAdV and other viruses. Subsequently, typing was conducted on HAdV specimens using single-plex real-time PCR assays targeting sequences in the hexon gene. Comparisons between HAdV types were performed to determine differences in characteristics and outcomes. Generalized linear mixed effects models were used to evaluate severity.
Results: Among the 1843 HAdV-positive cases, 1402 specimens (76%) were typed. The most common types detected were HAdV-C1 (n = 439), HAdV-C2 (n = 393), and HAdV-B3 (n = 221). Children with HAdV-B7 (n = 78) …

INTRODUCTION: World Health Organization global normative guidance recommends person-centred care (PCC) approaches to reduce HIV-related mortality and morbidity and to improve health-related quality of life (HrQoL). However, consensus on the priority PCC elements and guidance on how different stakeholders can realize PCC principles at the health systems, service delivery and individual client-healthcare worker (HCW) levels are lacking. We conducted a global consensus-building process to define core PCC elements and develop recommendations for implementation at scale.
METHODS: We used a multi-phase process to build consensus and prioritize recommendations, consisting of a literature review, five stakeholder consultations (34-43 participants each) between July …
