Clinicopathological Features Of Colorectal Cancer In Young Patients In Comparison With Older Patients, Bahaa Al-Neama, Wasam Al-Asadi

Iraqi National Journal of Medicine

Background:  Colorectal cancer (CRC) has traditionally been considered a disease of older adults; however, recent evidence shows an increasing incidence among younger patients. Understanding the differences in clinicopathological features between young and older individuals is essential for improving early diagnosis, treatment strategies, and outcomes. Aim: The primary objective of this study is to compare the demographic profiles and clinicopathological characteristics of younger patients (aged <40 years) with those of older patients (aged ≥40 years) diagnosed with colorectal cancer. Methods: Eighty-five consecutive patients admitted to our hospital were prospectively followed for their entire hospital stay or up to 7 days, whichever came first. Each patient's blood glucose measurement was recorded according to ward protocol. Indices included total blood glucose per ward, per patient-day, or patient stay, and percentage blood glucose levels per predefined cut points to assess the incidence of hypo-, eu-, and hyperglycemia. The trial registration number at Clinicaltrials.org is NCT04800861. Results: Total data consisted of 645 blood glucose tests from 85 patients and 284 patient-day results, with an average of 2.27 tests per patient-day and 7.59 measurements per patient stay. The percentage of blood glucose in the range (80–180 mg/dL) varied by model, with patient-day showing the highest results at 48.24%, while the percentage of patients with hypoglycemia (blood glucose <60 mg/dL) was highest per patient stay at 1.18%. Conclusions: Younger colorectal cancer patients in this study presented more frequently with rectal tumors, poor differentiation, and advanced disease stages. Despite similar symptom profiles, delayed diagnosis may contribute to worse pathological features. These findings support the need for greater awareness and consideration of earlier screening in younger populations.

Acute Isolated Unilateral Palatal Palsy In An Adolescent Girl: Case Report, Mueen Jawad Alabdullah, Sana Barwari

Iraqi National Journal of Medicine

Although reported in children, acquired and acute-onset isolated unilateral palatal palsy is a clinically rare condition. It is typically caused by involvement of the pharyngeal branch of the vagus nerve, with presenting symptoms primarily including acute-onset hypernasal speech and ipsilateral nasal regurgitation of fluids. While the etiology is often considered idiopathic, several pathologies, such as infections, trauma, tumors, and brainstem lesions, must be excluded, as direct associations have been established in literatures. We report a case of a 13-year-old girl who developed acute-onset left sided isolated palatal palsy following mild rhinitis with non-conclusive neuroimaging and negative routine serology. Complete recovery …

Faculty, Staff and Student Publications

Introduction: Blood-brain barrier (BBB) dysfunction has been associated with vascular dementia (VaD). However, the underlying mechanisms causing BBB dysfunction remain unclear, especially regarding cerebral hypoperfusion. This study aimed to investigate the effects of asymmetric hypoperfusion on BBB permeability using a mouse model of VaD.

Methods: Asymmetric bilateral common carotid artery stenosis (ACAS) was induced using ligature rings. BBB integrity was assessed on 3 days post-surgery using Evans blue, IgG, and albumin extravasation. A modified tissue processing protocol optimized endogenous marker detection. Regional and sex-based differences in BBB permeability were analyzed.

Results: Increased BBB permeability was observed in both corpus callosum …

Glutamatergic Projection Neurons In The Basal Forebrain Underlie Learned Olfactory Associational Valence Assignments, Pey-Shyuan Chin, Zhuokun Ding, Mikhail Kochukov, Snigdha Srivastava, Elizabeth H Moss, Qingchun Tong, Benjamin R Arenkiel

Faculty, Staff and Student Publications

Sensory perception is shaped by experience, giving stimuli behavioral significance. Basal forebrain (BF) cholinergic neurons in mice, which are crucial for arousal and motivation, also regulate sensory processing. Within BF nuclei, glutamatergic (vGlut2BF) neurons receive cholinergic input and modulate behaviors, but their roles in encoding sensory significance remain unclear. Using in vivo calcium imaging, we found that vGlut2BF neurons initially poorly encoded odor identity. However, their response to conditioned odors increased following associative learning, and their population activity more distinctly encoded paired stimuli, reflecting emergent value representation. Furthermore, pairing stimulation or inhibition of vGlut2BF neurons with specific odors altered odor …

Introduction: Effective therapies are needed for patients with NSCLC with HER2-mutant tumors who progress on the HER2 antibody-drug conjugate trastuzumab deruxtecan (T-DXd), a standard-of-care treatment. A greater understanding of mechanisms mediating acquired T-DXd resistance and whether these tumors could benefit from HER2 tyrosine kinase inhibitors (TKIs) is needed.

Methods: Using preclinical models of acquired T-DXd resistance, LentiMutate scanning mutagenesis, and clinical analyses, we investigated mechanisms mediating acquired resistance to T-DXd and assessed the impact of each of these resistance mechanisms on cross-resistance to alternative HER2-targeting approaches.

Results: We determined that acquired resistance to T-DXd could occur through multiple mechanisms including …

Faculty, Staff and Student Publications

Background: KMT2A partial tandem duplication (PTD) occurs in approximately 5-10% of acute myeloid leukemia (AML) cases and is associated with poor prognosis. While its cytogenetic and molecular features are well described, the immunophenotypic characteristics of AML with KMT2A-PTD remain incompletely defined.

Methods: We identified 47 cases of AML with KMT2A-PTD by optical genome mapping. All cases underwent flow cytometric immunophenotypic analysis and next-generation sequencing using an 81-gene panel.

Results: The cohort included 32 men and 15 women with a median age of 67 years (range, 19-87). Thirty-eight cases were de novo AML, and nine were secondary to myelodysplastic …

Epithelial-to-mesenchymal transition (EMT) is known to induce both stemness and mesenchymal properties, and our findings reveal that these two programs can be uncoupled. During EMT, epithelial cells transition from symmetric divisions producing differentiated daughter cells to self-renewing daughter cells. When we block cell division and induce EMT, cells gain mesenchymal properties but not stemness, suggesting the importance of cell division for gaining stemness. We identified ESRP1 as a key regulator of EMT-driven stemness, which get downregulated during EMT in a cell division-dependent manner. Overexpression of ESRP1 prevents the gain of stemness without affecting the mesenchymal program. Only the stemness and …

Patients with poorly differentiated thyroid cancer (PDTC) and anaplastic thyroid cancer (ATC) face a much poorer prognosis than those with differentiated thyroid cancers. Around 25% of PDTCs and 35% of ATCs carry the BRAFV600E mutation, which constitutively activates the MAPK pathway, a key driver of cell growth. Although combining BRAF and MEK inhibitors can shrink tumors, resistance often develops. The exact cause of this resistance remains unclear. We previously found that in PDTC and ATC cells, the BRAFV600E mutation is strongly linked to the expression of ETV5, a transcription factor downstream of the MAPK pathway. In the current study, we …

Acute myeloid leukemia (AML) is a clonal disorder characterized by immature blasts and arrested differentiation that primarily affects the bone marrow (BM) and occasionally presents as extramedullary (EM) disease. EM manifestations highlight AML's adaptability to distinct microenvironments, which we examined using spatial analyses of medullary and EM tissues. We describe a workflow for Visium-based spatial transcriptomics in medullary and EM AML, revealing insights into cell-cell communication and the spatial organization of AML hierarchies. In BM, monocytes and granulocyte-monocyte progenitors colocalized with leukemic populations, sharing molecular signatures with those in EM sample. CXCL12-CXCR4-mediated communication correlated with PI3K/AKT/mTOR signaling in inflammatory niches.

Selective Deletion Of Slc2a1 From The Rpe Reveals That Rods But Not Cones Depend On Glucose Transport Across The Outer Blood-Retinal Barrier, Lauren L. Daniele, John Y.S. Han, Minzhong Yu, Ravi A. Sangani, Craig D. Beight, Cyrus Rostami, Philip D. Kiser, Neal S. Peachy, Nancy J. Philp

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

GLUT1 facilitates a continuous flow of glucose across the inner and outer blood-retinal barriers (BRBs) to support vision. To understand the extent to which photoreceptors rely on glucose transport across the outer BRB, we generated a tamoxifen-inducible conditional knockout of Slc2a1 in the retinal pigment epithelium (RPE) (RPE-iΔGlut1). In the RPE-iΔGlut1 mice, rod photoreceptors exhibited impaired outer segment renewal and decreased the expression of proteins involved in phototransduction and ciliary transport. Proteins regulating the retinal stress response increased. Cone photoreceptors were functional and viable 15 months post-tamoxifen treatment in the RPE-iΔGlut1 mice, while 70% of the rods died. …

Lipid nanoparticle (LNP)-encapsulated nucleoside-modified mRNA vaccines elicit robust CD4+ T cell responses, yet the mechanisms underlying this T cell priming remain unknown. Antigens presented to CD4+ T cells on major histocompatibility complex class II (MHC II) are traditionally acquired by antigen presenting cells (APCs) from extracellular sources. Here we show that vaccine specific CD4+ T cell responses instead rely on antigen directly expressed within APCs, without extracellular transit. Murine APCs treated with mRNA-LNP vaccines activate T cells more efficiently when presenting antigen produced internally, rather than acquired externally. Immunization with mRNA-LNP vaccines engineered to inhibit antigen expression in APCs results …

Department of Neurology Faculty Papers

Introduction Single-cell RNA sequencing has elucidated the heterogeneity in cancer. Single-cell glioblastoma (GBM) analyses have also proposed the resemblance of GBM cells to radial glia and outer radial glia (oRG) supporting the hypothesis that remnants of developmental tissue get reactivated in cancer. A recent study isolated neural progenitor cells (NPCs) from developing fetal human brain (gestational week 17-19) and classified NPCs based on their expression of THY1 (CD90), CD24 and EGFR. Ventricular radial glia are THY1⁻CD24⁻EGFR⁺ whereas oRG are THY1⁻CD24⁻EGFR⁻. Early neuron precursors are CD24⁺THY1⁻EGFR …

The Ethical Limits Of Physician Autonomy In Reproductive Medicine, Isabel Martens

Honors Theses

In vitro fertilization is a relatively new medical practice that helps people who face infertility be able to reproduce. Reproductive medicine providers face ethical dilemmas often in their field, only some of which have standards of care. There are questions in the medical landscape pertaining to physician autonomy versus patient autonomy, which heavily apply to reproductive medicine providers. Patient autonomy is highly valued in medical ethics; however, physician autonomy should also be considered. When a physician decides who can and cannot reproduce, ethical considerations must be followed to maintain the practice of reproductive autonomy. Limited policies exist that manage reproductive …

Post-traumatic stress disorder (PTSD) exhibits extensive clinical and biological variability, making treatment challenging. The Consortium to Alleviate PTSD (CAP)-ketamine trial, the largest randomized study of ketamine for PTSD, found no overall benefit of ketamine over placebo, underscoring the necessity to identify responsive subgroups. Using pre-treatment blood DNA methylation profiles and clinical measures from the CAP-ketamine trial, we applied machine learning to predict treatment response. A model based on 1,208 methylation sites achieved higher predictive accuracy than models using clinical variables alone, and combining both data types further improved performance. The methylation-derived score distinguished responders with 92.9% accuracy. The predictive CpGs …

The dopaminergic system has a large role in behavior and neurological disease, and understanding dopamine level regulation in vivo is critical. To identify dopamine regulators, we utilized Drosophila melanogaster cuticle pigmentation, where dopamine is a precursor to melanin. We measured dopamine from known pigmentation mutants (e.g., tan, ebony, black) and performed an RNAi-based screen to identify additional regulators. We found 153 hits, enriched for developmental signaling pathways and mitochondria-associated proteins. From 35 prioritized candidates, 11 affected head dopamine levels. Effects on brain dopamine were mild, even knocking down the rate-limiting synthesis enzyme Tyrosine hydroxylase (TH), suggesting …

Extra-Axial Cerebrospinal Fluid Volumes From 6 To 24 Months Of Age Are Associated With Poorer Executive Function At School-Age In Children With And Without Autism, Yichi Zhang, Robert C Mckinstry, Natasha Marrus, John R Pruett Jr., Et Al.

2020-Current year OA Pubs

BACKGROUND: Abnormally increased extra-axial cerebrospinal fluid (EA-CSF) volume is present as early as 6 months in infants later diagnosed with autism and is associated with symptom severity at the age of diagnosis, but it is unknown whether early EA-CSF enlargement has long-term impacts on other clinical domains. Executive function (EF) deficits are frequently observed in children with autism and are linked with worse academic outcomes, higher anxiety, and lower adaptive functioning. The current study examines the association between EA-CSF volume at infancy and EF at school age in a longitudinally phenotyped cohort of children with either high (HL) or low …
