Dickson, Daniel Fatovich, Logan Hopkins, Eme John, Shirley Mcgough, Chloe Mclean, Irene Ngune, Alex Wheeler

Research outputs 2022 to 2026

Non-suicidal self-injury (NSSI), deliberate damage to body tissue with no intent to die, is not engaged with suicidal intent but is the most reliable predictor of later suicidal behaviour. This makes efforts to reduce self-injury critical. Emergency departments can be the gateways to care for many people who have self-injured and optimal sites for interventions that promote recovery. However, emergency nurses have anecdotally reported that they lack training and feel ill-equipped to provide care for patients who self-injure. In this open label trial (where both participants and researchers were aware who received the intervention), all nurses in a metropolitan emergency …

Center for Medical Ethics and Health Policy Staff Publications

Preimplantation genetic testing for polygenic disorders (PGT-P) has been commercially available since 2019. PGT-P makes use of polygenic risk scores for conditions which are multifactorial and are significantly influenced by environmental and lifestyle factors. If current predictions are accurate, then absolute risk reductions range from about 0.02% to 10.1%, meaning that between 10 and 5,000 in vitro fertilization patients would need to be tested with PGT-P to prevent one offspring from becoming affected in the future, depending on the condition and the number of embryos available. Survey and interview data reveal that patients and the public have largely favorable views …

A Sumo-Interacting Motif In The Guanine Nucleotide Exchange Factor Epac1 Is Required For Subcellular Targeting And Function, Wenli Yang, Fang Mei, Wei Lin, Jason E Lee, Si Nie, Christopher J Bley, André Hoelz, Xiaodong Cheng

The Brown Foundation: Institute of Molecular Medicine

Exchange protein directly activated by cAMP (EPAC1), a multifunctional intracellular cAMP receptor, dynamically localizes to various cellular loci, engaging with diverse molecular partners to maintain cellular homeostasis. The study investigates the role of the SUMO-interacting motif (SIM) in the subcellular targeting and cellular functions of EPAC1. It reveals that the SIM is a critical structural element for EPAC1's association with RanBP2/nucleoporin 358, a nucleoporin of the cytoplasmic filament component of the nuclear pore complex. Mutational disruption of EPAC1 SIM interferes with EPAC1's ability to activate its canonical effectors, small GTPases, Rap1 and Rap2, and noncanonical functions, such as the formation …

How Do Health Insurer Practices Affect Health Equity For Gay And Bisexual Men And Transmasculine Individuals? A Qualitative And Health Policy Assessment, Alexa D'Angelo

Dissertations and Theses

In the U.S. there continue to be stark disparities in health that affect LGBTQ+ communities. These disparities include those related to mental health, sexually transmitted infections, along with chronic illnesses and some cancers. Higher health needs across diagnostic categories mean that LGBTQ+ individuals require access to the healthcare system both to prevent conditions disproportionately affecting the community, and to treat conditions as they arise. In the U.S., access to healthcare often requires either reliable insurance coverage or another payer to cover costs associated with care. Thus, health insurance status and coverage of care, along with coverage regulations and health policies …

The complex interplay of mental health challenges, combat exposure, and the unique stressors associated with military service contribute to a heightened vulnerability among veterans. Research from the United States Department of Veterans Affairs (USDVA) underscores the prevalence of these issues, indicating that approximately 1 in 10 veterans from the Iraq or Afghanistan wars treated by the VA are diagnosed with a SUD (Veterans Affairs, 2023). Additionally, veterans from all eras show a higher propensity for binge drinking when compared to the general population, further …

The Rose That Grew From Concrete: Exploring The Romantic Experiences Of Black Men With Histories Of Childhood Sexual Abuse, Tatyana Nichelle Smith

Dissertations

Contemporary research typically characterizes Black heterosexual relationships by dismal marriage and divorce rates, largely ignoring the reality of how Black men develop attachments with their romantic partners and therefore continuing to perpetuate deficit perspectives of Black men (e.g., the cause of conflictual romantic relationships and “broken” Black families). What may be less understood about these relationships is the influence of childhood trauma, such as childhood sexual abuse, and Black men’s experiences of gender role conflict. Research shows that Black men’s experiences of childhood sexual abuse and socialization about masculinity have important implications for how they come to view themselves and …
