Untangling Familicide: A Comparison Of Three Definitions, Lesley M. Vega Dec 2025

Untangling Familicide: A Comparison Of Three Definitions, Lesley M. Vega

Electronic Theses, Projects, and Dissertations

Familicide is generally defined as the killing of multiple family members by a relative. However, there is no single, universally accepted definition of familicide, and different studies use varying definitions with different inclusion criteria. Sometimes, very restrictive definitions are used that exclude many similar cases (e.g., father kills spouse and children). Conversely, broader definitions sometimes overlap with other phenomena, such as mass murder. Only a few studies have examined this phenomenon, primarily from an exploratory standpoint.

Case data was collected from the Gun Violence Archive, an online database that records shooting incidents in the United States, for familicidal events that …

Electronic Theses, Projects, and Dissertations

Schools play a significant role in the academic, behavioral, and social-emotional development of children. Students with disabilities have legal rights to all necessary support for their educational success, including mental health supports. School-based mental health and its implementation are a work in progress, facing many barriers, but the benefits speak for themselves. Research suggests that the use of a multi-tiered system of supports ensures equal and equitable interventions for all students, especially students with disabilities. This literature review analyzes 16 studies regarding school-based mental health, special education, students with disabilities, and the MTSS framework. Support students' mental health, regardless of …


Requirement Of Prepiilin Peptidase Activity For Variovorax Paradoxus Eps Flp/Fap Pilus Assembly, Jenny L. Lanthripp Dec 2025

Requirement Of Prepiilin Peptidase Activity For Variovorax Paradoxus Eps Flp/Fap Pilus Assembly, Jenny L. Lanthripp

Electronic Theses, Projects, and Dissertations

Variovorax paradoxus is a Gram-negative aerobic bacterium present in both soil and the human oral microbiome. This species contributes to biotransformation of xenobiotics and promotes plant growth. Interestingly, although the genome of strain EPS lacks the flagellum operon annotated in strain S110, the microbe remains motile, and flagella can be observed microscopically. To investigate this unexpected phenotype, motility mutants were enriched from a Tn5 mutant library using a liquid culture settling strategy. A total of 122 isolates were screened for motility defects, and 57 exhibited significantly reduced motility compared to the wild type. Rescue cloning revealed that over 60% of …

Faculty, Staff and Students Publications

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. Patients with clinical or imaging evidence of device infection should …

Breast, prostate and lung cancer cells frequently metastasize to bone, leading to disruption of the bone microstructure. This study utilized mechanical testing coupled with micro-CT imaging, digital volume correlation (DVC), and atomic force microscopy (AFM) nanomechanical testing to examine the mechanical property variations in mouse long bones (tibia) with metastatic lung cancer cell involvement, spanning from the whole-bone scale to the microstructural level. In addition, we also investigated how metastatic invasion alters the morphology of hydroxyapatite nanocrystals in bone at the nanometer scale. The biochemical composition within metastatic lesions was assessed using Raman spectroscopy and correlated with AFM mechanical testing …

Biochemical And Clinical Response To A Sulfur-Restricted Diet In Ethylmalonic Encephalopathy, Steven H Lang, Andres Caceres Salgado, Matthew T Snyder, Brandy Rawls-Castillo, Aaron Williams, Charul Gijavanekar, Sarah H Elsea, Xia Wang, Mary Elizabeth M Tessier, Claudia Soler-Alfonso, Fernando Scaglia

Faculty, Staff and Students Publications

Introduction: Ethylmalonic encephalopathy (EE) is an often-severe inborn error of metabolism caused by biallelic variants in the ETHE1 gene leading to impaired detoxification of hydrogen sulfide (H2S). H2S is produced both exogenously by anerobic intestinal bacteria as well as by the endogenous catabolism of the sulfur-containing amino acids methionine and cysteine. Existing therapies including metronidazole, N-acetylcysteine (NAC), and orthotopic liver transplantation (OLT) have been pursued with the objective of reducing or detoxifying exogenously produced H2S. However, strategies to reduce endogenously produced H2S using a methionine and cysteine restricted diet are an understudied therapeutic avenue.

Methods: We performed an open-label, …

Clinical Exome Sequencing Efficacy And Phenotypic Expansions Involving Non-Isolated Congenital Anomalies Of Kidney And Urinary Tract (Cakut+), E Andres Rivera-Munoz, Xiaonan E Zhao, Jill A Rosenfeld, Pamela N Luna, Chad A Shaw, Jennifer E Posey, Daryl A Scott

Faculty, Staff and Students Publications

Congenital Anomalies of Kidney and Urinary Tract (CAKUT) can occur in isolation or in conjunction with one or more non-CAKUT associated congenital anomalies or neurodevelopmental disorders (CAKUT+). A molecular cause is not identified in most individuals with CAKUT+. This is due, in part, to uncertainty regarding the efficacy of genetic testing and an incomplete understanding of the genes that cause CAKUT+. Here, we use data from 515 individuals with CAKUT+ (n = 500) or isolated CAKUT (n = 15) to determine the efficacy of clinical exome sequencing (cES) and to identify new phenotype expansions that involve CAKUT. We determined that …

Apathy is characterized by loss of motivation and manifests as a reduction of goal-directed behavior. Apathy is highly prevalent across neurodegenerative diseases, including Alzheimer's Disease (AD) and Parkinson's Disease (PD), and is an important contributor to the disability and reduce quality of life in these conditions. The treatment of apathy remains challenging due to a lack of specific therapies, largely attributed to an incomplete understanding of its cognitive and neuroanatomical underpinnings, crucial for developing targeted interventions. Apathy can be mechanistically studied through effort-based decision-making (EBDM) paradigms, where individuals choose between low- and high-effort tasks for varying reward magnitudes. Anatomically, apathy …

Despite their importance for brain function, cortico-subcortical white matter tracts are under-represented in diffusion magnetic resonance imaging tractography studies. Their non-invasive mapping is more challenging and less explored compared to other major cortico-cortical bundles. We introduce a set of standardised tractography protocols for delineating tracts between the cortex and various deep subcortical structures, including the caudate, putamen, amygdala, thalamus, and hippocampus. To enable comparative studies, our protocols are designed for both human and macaque brains. We demonstrate how tractography reconstructions follow topographical principles obtained from tracers in the macaque and how these translate to humans. We show that the proposed …

Net Clinical Benefit Of Patiromer For Acute Hyperkalemia: A Post-Hoc Analysis Of The Reduce Trial, Robert Mcarthur, W Frank Peacock, Jeff Budden, Zubaid Rafique

Faculty, Staff and Students Publications

Introduction: Hyperkalemia (HK) is a common and potentially life-threatening electrolyte disturbance managed with potassium (K)-shifting medications and potassium binders. The use of K-shifting agents is a confounder when assessing the effects of K-binding treatments in clinical trials. Patiromer is a K-binding agent with demonstrated efficacy for the management of chronic hyperkalemia. As both changes in sK level and the number of interventions required to lower potassium are clinically relevant, we propose an evaluation using Net Clinical Benefit (NCB), defined as the number of K shifting interventions less the numerical change in K.

Methods: We conducted a post-hoc analysis of the …

The reprogramming of alternative splicing networks during development is a hallmark of tissue maturation and identity. Alternative splicing of microexons (small, genomic regions ≤ 51 nucleotides) functionally regulate protein-protein interactions in the brain and is altered in several neuronal diseases. However, little is known about the regulation and function of alternatively spliced microexons in striated muscle. Here, we investigated alternative splicing of a microexon in the synaptosome-associated protein 23 (Snap23) encoded gene. We found that inclusion of this microexon is developmentally regulated and tissue-specific, as it occurs exclusively in adult heart and skeletal muscle. The alternative region is …


A Narrative Review Of Dual Loyalty Conflicts In Custodial Settings And Implications For Community Practice, Michelle Suh, Marc David Robinson, Holland Kaplan Dec 2025

A Narrative Review Of Dual Loyalty Conflicts In Custodial Settings And Implications For Community Practice, Michelle Suh, Marc David Robinson, Holland Kaplan

Center for Medical Ethics and Health Policy Staff Publications

Dual loyalty dilemmas are conflicts between health care professionals' obligations toward their patients and third-party interests. These conflicts are more common and starker in custodial settings, such as jails and prisons, military detention facilities, immigration detention centers, and involuntary psychiatric institutions. Despite encountering patients in custody, health care professionals (HCPs) in community settings have limited knowledge and training. In this narrative review, we examined dual loyalty conflicts faced by HCPs working in custodial settings and then applied the identified themes to community-based hospitals where HCPs care for patients in custody. We searched databases for original papers relating to patients in …

Objective: Many young children with isolated skull fractures are referred to child protective services (CPS) despite being assessed to have a low likelihood of abuse. We sought to identify factors associated with CPS referrals in this population and to quantify hospital-level variation.

Methods: We performed a multicenter retrospective cross-sectional study of children < 2 years with skull fractures with or without a small underlying intracranial hemorrhage (ICH) and no additional injuries undergoing a child abuse pediatrics (CAP) subspecialty evaluation. We explored associations between demographic factors, clinical characteristics, psychosocial risk factors, and hospital site with CPS referral status. We performed multivariable logistic regression, adjusting for transfer status and all significant covariates from unadjusted analyses. We utilized marginal standardization to calculate the estimated probability of CPS referrals at each site, adjusting for all factors in the final model.

Results: Of 528 children, 303 (57.4%) were referred to CPS, with 86.5% referred prior to CAP consultation. In multivariable logistic regression, presence of psychosocial risk factors (OR 4.00; 95% CI 2.25, 7.11), in-person CAP consult (OR 3.93; 1.61, 9.62), inflicted or no trauma history provided (OR 6.15; 3.30, …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Primary sarcopenia is an age-associated disorder with progressive and generalised loss of skeletal muscle strength and mass. Skeletal muscle fibrosis is one of the significant pathological manifestations of age-associated sarcopenia. Decorin, a small dermatan-sulfate proteoglycan, participates in extracellular matrix assembly. In numerous studies, the involvement of decorin is not restricted to matrix structural proteins, and it also affects a diverse variety of biological functions like cell growth, adhesion, migration, proliferation and differentiation. Additionally, it modulates the process of inflammation and fibrillogenesis. Based on these preclinical evidences, we hypothesised that decorin may potentially play an important role in skeletal muscles …
