Nmda Receptor Subunit Nmr-2 Regulates Pathogen-Induced Immune Responses Via The Nervous System In C. Elegans, Benson Otarigho, Jonathan Lalsiamthara, Alejandro Aballay

Faculty, Staff and Student Publications

Neural control of innate immunity must balance restraint of basal immune activity with rapid activation upon pathogen encounter. Glutamate, the primary excitatory neurotransmitter in the nervous system, has been implicated in several neurological disorders associated with inflammation, suggesting a potential link to immune regulation. However, how glutamatergic signaling contributes to immune balance remains unknown. Here, we demonstrated that the NMDA-type ionotropic glutamate receptor subunit NMR-2, a component of the NMDA receptor complex, acts in the

Background/objectives: Quality improvement (QI) is widely used in global health to improve patient outcomes, reduce costs, and strengthen service delivery. The Texas Children's Global Health Network (TCGHN) includes nine independent non-governmental organizations supporting healthcare in low- and middle-income countries (LMICs), with pediatric HIV clinical centers of excellence in six countries in sub-Saharan Africa (SSA), supported technically by Baylor College of Medicine. We describe the development of a virtual QI Community of Practice (QICoP) to connect geographically dispersed teams and strengthen local QI capacity.

Methods: In 2022, QI and global health experts convened to design the QICoP and assess site readiness. …

Secondary Cutaneous Involvement In Peripheral T-Cell Lymphoma: Diagnostic Frameworks, Staging Integration, And Therapeutic Implications, Aura Calderon, Jose Loayza Pintado, Cristina Kochi, Jared Hensley, Andres Suarez Parraga, Everardo Cobos

School of Medicine Publications

The occurrence of secondary cutaneous manifestations in peripheral T-cell lymphoma (PTCL) is relatively infrequent and can resemble benign dermatoses, leading to diagnosis delays. We present the case of a 78-year-old female patient with a diagnosis of PTCL affecting the left parotid gland, who experienced a 2-day sudden and intensely pruritic skin eruption, which progressed from both forearms to the trunk, involving more than 50% of the total body surface area. Initially, the eruption was managed as a hypersensitivity reaction with antihistamines and corticosteroids, with temporary symptomatic relief; however, the rapid clinical progression in the context of an established diagnosis of …

BACKGROUND: We aimed to investigate and characterise DILI due to approved therapies for inflammatory bowel disease (IBD).

METHODS: Using the Drug-Induced Liver Injury Network (DILIN) prospective study, we evaluated definite, highly likely, or probable DILI attributed to IBD therapies, including use for non-IBD indications (but excluding corticosteroids). HLA allele associations were investigated.

RESULTS: Among 1806 participants, 81 (4.5%) had IBD-agent DILI: 31 biologics (27 infliximab), 35 immunomodulators (31 azathioprine/mercaptopurine), 14 aminosalicylates (11 sulfasalazine) and 1 small molecule (tofacitinib). Median age was 45 years with 75% female and 78% White. Patients with biologic-DILI were younger, had longer latency (median 124 days), …

Evaluating Outcomes Of Alternative Pathologic Terminology In High-Grade Dysplastic Colorectal Lesions, Shaman Dalal, Aakash Desai, Nahel Tunio, Jacqueline Khalil, Devereaux Sellers, Marc Landsman

Division of Gastroenterology and Hepatology Faculty Papers

Background Pathologists occasionally classify colorectal adenomas with dysplastic mucosal invasion as intramucosal carcinoma (IMC), or carcinoma in situ (CIS), instead of high-grade dysplasia (HGD), potentially leading to earlier surveillance colonoscopies and inappropriate surgical referrals. We aimed to analyze differences in the management of patients with these diagnoses, and examined the factors that may lead to inappropriate early interval (IEI) follow-up recommendations for surveillance.

Methods We reviewed 870 colonoscopy and pathology reports from 2015-2022, excluding cases of colorectal cancer, inflammatory bowel disease, and lesions not amenable to endoscopic resection. Surveillance appropriateness was defined in accordance with the 2020 US Multi Society …

Agreement Among Experienced Physical Therapist Clinicians In Naming Nystagmus: A Mixed-Methods Study Design, Lori Ann Leineke, Alessandra N. Garcia, Bridget Eubanks

Internet Journal of Allied Health Sciences and Practice

Purpose: Labeling nystagmus requires clinicians to consider multiple aspects of its presentation. The extent to which physical therapists (PTs) use consistent terminology for describing nystagmus is unknown. Recommendations for proper terminology exist, but adherence during clinical assessment has not been determined. This study investigated whether PTs with advanced vestibular rehabilitation skills and training consistently use standardized vocabulary to describe nystagmus patterns. Methods: This descriptive, cross-sectional, mixed-methods study utilized an online survey methodology, which included eight free-response questions. Participants viewed videos of nystagmus through Infrared or Frenzel goggles and documented their observations. A codebook of responses was created for each question, …

Brain and Mind Institute

Background: Adverse Childhood Experiences (ACEs) have been consistently linked to poor mental health outcomes, yet research on their impact in low- and middle-income countries (LMICs) settings of Africa, remains relatively unexplored. In Kenya, where childhood adversity is widespread, there is a critical need to examine the validity of ACE measures and their associations with mental ill health. This study aimed to validate the Adverse Childhood Experiences questionnaire (ACE-10) in a Kenyan adolescent sample and assess its associations with symptoms of depression and anxiety, bullying, and sociodemographic factors.

Methods: Data was collected from N = 2,842 adolescents and young …

Radiotheranostics For Gynecological Pathologies, Joni Sebastiano

Dissertations, Theses, and Capstone Projects

Molecular imaging, specifically positron emission tomography (PET), is vital for detecting disease and understanding its biological makeup. The exploitation of radiolabeled antibodies for PET imaging has proven to be indispensable to the field of molecular imaging over the last several decades. The development of radioimmunoconjugates for use in immunoPET has not only allowed for the sensitive, specific, and high-resolution detection of disease, but has also enabled a deeper understanding of the disease biology, ultimately guiding more personalized therapeutic strategies. Most typically, this technology is harnessed for the diagnosis and treatment of cancer, however more recently, the field has explored the …

Research outputs 2022 to 2026

Background: Osteosarcopenia—the coexistence of osteopenia/osteoporosis and sarcopenia—is associated with numerous adverse health outcomes, but its association with intrinsic capacity (IC) remains unknown. We aimed to explore the associations of osteosarcopenia with IC and all-cause mortality in older adults. Methods: We conducted a cross-sectional analysis of IC and a prospective analysis of all-cause mortality in 1142 participants from the Toledo Study for Healthy Aging (75.1 ± 6.0 years, 53.1% women). Participants were classified as having no musculoskeletal disorders, osteopenia/osteoporosis, sarcopenia, or osteosarcopenia (DXA- and EWGSOP2-based criteria). IC was operationalized as a composite score integrating locomotion, cognition, psychological, vitality, and sensory domains. …

Brain and Mind Institute

Background. Safety supports psychological wellbeing and potentially shapes brain aging yet existing scales overlook cumulative lifespan safety experiences.

Methods. To address this gap, we developed and validated the Lifetime Sense of Safety (LSS) scale in Kenyan adults. The LSS uses visual analog scaling with a red-to-green color gradient to retrospectively rate felt safety across life stages and settings. We evaluated scale psychometrics and associations with social determinants of health and indicators of brain health.

Results. The LSS shows adequate internal consistency and test-retest reliability, with two distinct but correlated factors representing childhood and adulthood safety. Women and …

Contextual Variability In Under-Diagnosed Cardiometabolic Disease And Cognitive Vulnerability Among Populations At High Risk For Alzheimer's Disease And Related Dementias, Nwanyieze Jiakponnah, Joseph Curran, Tamlyn Watermeyer, Jasmit Shah, Litha Musili, Stanely Onyango, Benard Aliwa, Zul Merali, Karen Blackmon, Chinedu Momoh

Brain and Mind Institute

Underdiagnosis of cardiometabolic risk factors (CMRFs) may represent an unrecognised biological pathway contributing to dementia risk; yet remains poorly characterised in African and African diaspora populations. We quantified the prevalence and determinants of underdiagnosed hypertension and abnormal glycaemia across four cohorts comprising up to 7000 adults aged ≥40 years from Nigeria, Kenya, and The United States: Indianapolis, and North Texas. Underdiagnosis was defined as absence of self-reported diagnosis despite elevated systolic blood pressure ( ≥130 mmHg) or fasting blood glucose ( ≥100 mg/dL). Cohort-stratified analyses examined demographic, socioeconomic, cognitive, Alzheimer’s genetic, and blood-based biomarker correlates. Underdiagnosis was pervasive in African …
