Department of Dermatology and Cutaneous Biology Faculty Papers

Acral lentiginous melanoma (ALM) classically presents in glabrous skin. Some studies suggest an association between mechanical stress and ALM development. People working jobs with long periods of standing/walking may be exposed to near-daily mechanical stress. To investigate the relationship between occupation type and ALM development, we performed a retrospective cohort study using Optum’s Clinformatics Database (2007—2023). We compared the risk of ALM in adults with occupational data (n = 9,270,935). Retired patients had the highest prevalence (0.081) and incidence per 1,000,000 person-years (0.514, 95% confidence interval = 0.487—0.542) of ALM. We performed multivariate logistic regression, adjusted for demographics and insurance, …

Abstract

Background

Most US individuals with ADRD are women. Menopause typically occurs in midlife, accompanied by declines in potentially neuroprotective and cardioprotective hormones. Earlier menopause leads to earlier exposure to decreased sex hormones, potentially increasing ADRD risk. Surgical menopause via reproductive surgeries may cause a sudden loss of hormones and may represent be a modifiable risk factor for ADRD. We aimed to determine if menopausal type and age are associated with physician adjudicated-ADRD diagnoses.

Methods

Data were from 3371 women prospectively followed from age 65+ years. Participants self-reported age of menopause and/or surgeries, hormone-therapy, education, and race (Black/White). For this …

Antiseizure Medications And Their Differing Effects On Cardiovascular Risk, Aleena Abbasi, Bassil Abbasi, Scott Mintzer, Carla Lopinto-Khoury

Department of Neurology Faculty Papers

This review discusses the differing effects of enzyme-inducing and non-inducing antiseizure medications on cardiovascular risk and their implications for the management strategies of epilepsy patients. Traditional risk markers, including low density lipoprotein, high density lipoprotein and triglycerides, can be altered by both enzyme induction and inhibition. Other markers of vascular risk, including c-reactive protein, non-high-density lipoprotein and homocysteine, are affected by antiseizure medications, although adults and children may have different responses. The overall atherosclerotic risk picture is more complex due to indirect effects such as neuroendocrine function and the metabolic syndrome. Large scale data shows an evolving understanding of cardiovascular …

Background: While often life-saving, treatment for head and neck cancer (HNC) can be debilitating resulting in unplanned hospitalization. Hospitalizations in cancer patients may disrupt treatment and result in poor outcomes. Pre-treatment muscle quality and quantity ascertained through diagnostic imaging may help identify patients at high risk of poor outcomes early. The primary objective of this study was to determine if pre-treatment musculature was associated with all-cause mortality.

Methods: Patient demographic and clinical characteristics were abstracted from the cancer center electronic database (n = 403). Musculature was ascertained from pre-treatment CT scans. Propensity score matching was utilized to adjust for confounding …

Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. Its incidence has grown alongside the increasing global prevalence of type 2 diabetes, obesity, and metabolic syndrome. The risk of progression to hepatocellular carcinoma for nonalcoholic steatohepatitis patients over 5 years is 8%, and despite targeted and immunotherapy treatment advances, HCC maintains a bleak 5-year survival of 19%. NAFLD’s primary risk factors are components of metabolic syndrome as well as possible sleep disturbances. NAFLD is most common among men 50-60 years of age, though incidence in women catches up after menopause. In the US, Hispanics are …
