Comparison Of Positivity Rate Of Dual Phase Sestamibi Versus Dual Tracer Pertechnetate/Sestamibi In Identification Of Parathyroid Adenomas., Naomi Chirindo Chikuro

Master of Medicine in Imaging and Diagnostic Radiology

Background 

Parathyroid adenomas are the commonest cause of primary hyperparathyroidism. The primary mode of treatment is surgical excision which can only be achieved with pre surgical localization of adenomas. Ultrasound, CT and MRI can be used but the most sensitive and specific imaging modality is parathyroid scintigraphy with use of Sestamibi labelled with technetium 99 metastable radionuclide. A few studies have been done comparing dual phase, dual tracer and combined dual phase/tracer protocols with an apparent lack of consensus on which is superior.

This study aimed to compare the positivity rates of the mentioned parathyroid scintigraphy protocols and identify …

The Prevalence And The Predictors Of Diabetes Distress In Patients With Type 2 Diabetes Attending Diabetes Clinics At A Tertiary Private Hospital In Nairobi, Kenya., Soulthy Azamkhan Mohamed

Master of Medicine in Family Medicine

Background Diabetes distress encompasses a spectrum of emotional and psychological challenges faced by individuals managing diabetes, including anxiety, stress, depression, frustration, and feelings of helplessness. This distress arises from the constant demands of monitoring blood sugar levels, managing medications, adhering to dietary restrictions, engaging in regular physical activity, and navigating potential complications. Social and emotional factors such as stigma, discrimination, and concerns about future health further contribute to this burden. Factors like fear of hypoglycemia, financial strain, fluctuating blood sugar levels, anxiety about complications, and impacts on personal relationships exacerbate diabetes distress. Left unaddressed, diabetes distress can lead to poor …

Diagnostic Accuracy Of 18f-Fdg Pet-Ct Compared To Ultrasound In Identification Of Metastatic Axillary Lymph Nodes In Newly Diagnosed Breast Cancer Patients., Sarah Muthii Kibe

Master of Medicine in Imaging and Diagnostic Radiology

Background: Determination of axillary lymph node metastasis is a crucial part of breast cancer staging as it is the most important marker of overall recurrence and survival. Although axillary ultrasound (AUS) is the imaging reference standard, it has a wide range of sensitivity necessitating evaluation of other imaging modalities that may be used as adjuncts.18F-FDG PET-CT is recommended for use in metastatic and recurrent breast cancer with infrequent use in early disease due to its low spatial resolution for small axillary lymph nodes. The aim of this it study is to evaluate the diagnostic accuracy of axillary ultrasound compared …

Although the precise underlying cause(s) of autism spectrum disorder remain unclear, more than 1000 rare genetic variations are associated with the condition. For many people living with profound autism, this genetic heterogeneity has impeded the identification of common biological targets for therapy development for core and comorbid traits that include significant impairments in social communication and repetitive and restricted behaviors. A substantial number of genes associated with autism encode proteins involved in signal transduction and synaptic transmission that are critical for brain development and function. CAMK4 is an emerging risk gene for autism spectrum disorder that encodes the CaMK4 (calcium/calmodulin-dependent …

Cerebrotendinous Xanthomatosis Occurs At High Frequency In Ashkenazi Jews, Jennifer Hanson, Penelope E Bonnen

Faculty, Staff and Students Publications

Cerebrotendinous Xanthomatosis (CTX) is a treatable, inborn error of bile acids metabolism caused by pathogenic variants in CYP27A1. CTX is a multi-organ system disorder that progresses over decades. Clinical features include cerebellar dysfunction, pyramidal tract dysfunction, cognitive deficits and decline, peripheral neuropathy, chronic diarrhea, bilateral cataracts, and tendon xanthomas. Treatment is effective when started early, but diagnostic delays often result in individuals not being diagnosed until after the window of highest treatment efficacy. CTX is documented to occur in most global populations, however, no CTX-causing genetic variants have been reported in Ashkenazi Jews. We conducted a systematic review of every …

Exploring Oxylipins In Host–Microbe Interactions And Their Impact On Infection And Immunity, Robert J. Neff, Christopher D. Radka

Markey Cancer Center Faculty Publications

Plasma lipids are essential components of biological systems, transported through interactions with proteins to maintain cellular functions. These lipids exist in various forms, such as fatty acids, glycerolipids, glycerophospholipids, sphingolipids, sterols, and prenol lipids, derived from dietary intake, adipose tissue, and biosynthesis. While the association between certain fatty acids and cardiovascular diseases has been widely recognized, polyunsaturated fatty acids (PUFAs) exhibit cardioprotective effects, reducing risks of arrhythmias and heart-related mortality. This is due to their role in the production of eicosanoids, which modulate inflammation. Chronic inflammation, particularly in obesity, is significantly influenced by fatty acids, with saturated fatty acids promoting …

Functional Investigation Of A Putative Calcium-Binding Site Involved In The Inhibition Of Inositol 1,4, 5-Trisphosphate Receptor Activity, Vikas Arige, Larry E Wagner, Sundeep Malik, Mariah R Baker, Guizhen Fan, Irina I Serysheva, David I Yule

Faculty, Staff and Student Publications

The regulation of inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) activity is thought to define the spatiotemporal patterns of Ca2+ signals necessary for the appropriate activation of downstream effectors. The binding of both IP3 and Ca2+ is obligatory for IP3R channel opening. Ca2+ however regulates IP3R activity in a biphasic manner. Ca2+ binding to a high-affinity pocket formed by the third armadillo repeat domain and linker domain promotes IP3R channel opening without altering the Ca2+ dependency for channel inactivation. These data suggest that a distinct low-affinity Ca2+-binding site is responsible for the reduction in IP3R activity at higher [Ca2+]. We mutated a …

Which Systemic Responses Should We Evolve To Help Surgeons Navigate Their Regret Experiences?, Ryan X Lam, Ruhi Thapar, Eric J Silberfein, Lorenzo R Deveza

Faculty, Staff and Students Publications

Regret in surgical practice is typically construed as resulting from the commission or the omission of a specific action at a specific decision point, which leads to a deleterious outcome. This article suggests a need to expand this conception of surgical regret to better account for surgeons' regret experiences arising from factors beyond their control. The commentary accompanying the case investigates these external sources of regret, such as resource limitations or professional interpersonal dynamics that prevent a desired outcome from being realized. It also discusses the normative value of addressing surgeons' experiences of regret, especially as a catalyst to facilitate …

Vaginal fibrosis induced by cancer therapy continues to take a physical and psychoemotional burden. To advance the efforts to generate a reproducible and cost-effective animal model, we tested the effect of repeated bleomycin instillations with mucosal layer disruption on induction of vaginal fibrosis. Tissue samples collected at various time points were analyzed for fibrosis-related gene expression changes and collagen content. Low (1.5 U/kg) and high-dose (2.5 U/kg) bleomycin instillations alone did not induce fibrosis, but when high-dose bleomycin was combined with epithelial disruption, increased profibrotic gene expression and trichrome staining were observed. To evaluate spatial and temporal changes in the …

Faculty, Staff and Students Publications

Background: Surgical planning for orthognathic procedures demands swift and accurate biomechanical modeling of facial soft tissues. Efficient simulations are vital in the clinical pipeline, as surgeons may iterate through multiple plans. Biomechanical simulations typically use the finite element method (FEM). Prior works divide FEM simulations into increments to enhance convergence and accuracy. However, this practice elongates simulation time, thereby impeding clinical integration. To accelerate simulations, deep learning (DL) models have been explored. Yet, previous efforts either perform simulations in a single step or neglect the temporal aspects in incremental simulations.

Purpose: This study investigates the use of spatiotemporal incremental modeling …

Several reports have demonstrated that CD147, an N-glycosylated protein that is exchanged by cells in soluble form or through small extracellular vesicles (sEVs), can promote cancer progression. However, its activity related to EVs in colorectal cancer (CRC) is still not fully understood. Previously, we showed that sEV secretion during CRC stem cell (CR-CSCs) differentiation is partially controlled by CD147, and that CD147-expressing sEVs (sEVs-CD147) activate a signalling cascade in recipient cells, inducing molecular invasive features in CR-CSCs. In the present study, we demonstrated that sEVs-CD147 increase the expression of myofibroblast and activation markers in cancer-associated fibroblasts (CAF). In sEVs-CD147-activated CAF, …

Antigen-presenting cells phagocytose tumor cells and subsequently cross-present tumor-derived antigens. However, these processes are impeded by phagocytosis checkpoints and inefficient cytosolic transport of antigenic peptides from phagolysosomes. Here, using a microbial-inspired strategy, we engineered an antibody-toxin conjugate (ATC) that targets the 'don't eat me' signal CD47 linked to the bacterial toxin listeriolysin O from the intracellular bacterium Listeria monocytogenes via a cleavable linker (CD47-LLO). CD47-LLO promotes cancer cell phagocytosis by macrophages followed by LLO release and activation to form pores on phagolysosomal membranes that enhance antigen cross-presentation of tumor-derived peptides and activate cytosolic immune sensors. CD47-LLO treatment in vivo significantly …

Proteasome Augmentation Mitigates Age-Related Cognitive Decline In Mice, Danitra Parker, Kanisa Davidson, Pawel A Osmulski, Maria Gaczynska, Andrew M Pickering

Faculty, Staff and Student Publications

The aging brain experiences a significant decline in proteasome function. The proteasome is critical for many key neuronal functions including neuronal plasticity, and memory formation/retention. Treatment with proteasome inhibitors impairs these processes. Our study reveals a marked reduction in 20S and 26S proteasome activities in aged mice brains, including in the hippocampus, this is driven by reduced functionality of aged proteasome. The decline in proteasome activity is matched by a decline in 20S proteasome assembly. In contrast, 26S proteasome assembly was found to increase with age, though 26S proteasome activity was still found to decline. Our data suggests that age-related …
