Background: Leptomeningeal dissemination (LMD) occurs when tumor cells interact with choroid plexus epithelium (CPE) to gain access to cerebrospinal fluid (CSF) in the brain's meninges and ventricular system. This disease is particularly devastating for patients due to our limited understanding and few therapeutic options. The leptomeningeal CSF is a nutritionally deprived microenvironment for tumor cells.

Updates in Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis.

Gastroenterol Clin North Am

March 2025

Division of Gastrointestinal and Liver Diseases, Department of Medicine, Keck School of Medicine, University of Southern California, Los Angeles, Los Angeles, California, USA. Electronic address:

Although endoscopic retrograde cholangiopancreatography (ERCP) has been shown to be a safe and effective approach in treating these diseases while carrying lower morbidity than traditional surgical treatments, ERCP has associated risks, with post-ERCP pancreatitis (PEP) being the most common serious adverse event and carries significant morbidity and health care cost. PEP results from multifactorial factors involving trauma to the pancreatic duct and papilla, leading to subsequent obstruction and impairment of pancreatic drainage. Important risk factors for PEP include history of prior PEP, suspected sphincter of Oddi dysfunction, difficult cannulation, pancreatic duct contrast injections, and pancreatic sphincterotomy.

Circulating microRNAs and alcohol consumption in the Multiethnic Cohort Study.

Alcohol

January 2025

Department of Population and Public Health Sciences, Keck School of Medicine, University of Southern California, Los Angeles, CA; Norris Comprehensive Cancer Center, University of Southern California, Los Angeles, CA; Center for Genetic Epidemiology, Keck School of Medicine, University of Southern California, Los Angeles, CA.

Excessive alcohol consumption is a significant public health concern and contributes to liver diseases and cancer. Modifiable lifestyle factors including alcohol consumption can influence circulating microRNAs (miRNAs), which are increasingly used as biomarkers for early disease detection. Yet limited studies have identified miRNAs associated with alcohol intake, particularly in multiethnic populations.

Program Director Perspectives on DEI Initiatives in the Dermatology Residency Selection Process.

Cutis

December 2024

Ogechi Obed, Ivan Rodriguez, and Dr. Worswick are from the Department of Dermatology, Keck School of Medicine, University of Southern California, Los Angeles. Karen Lam is from the Department of Dermatology, David Geffen School of Medicine, University of California Los Angeles. Dr. Van Beek is from the Department of Dermatology, University of Iowa Health Care, Iowa City. Dr. Rosenblatt is from the Section of Dermatology, Departments of Medicine and Pediatrics, University of Chicago Pritzker School of Medicine, Illinois. Dr. Saavedra is from the Department of Dermatology, University of Virginia School of Medicine, Charlottesville.

The American Academy of Dermatology (AAD) has maintained a commitment to diversity, equity, and inclusion (DEI) initiatives; however, a recent strike down of affirmative action by the US Supreme Court has caused similar efforts to be called into question. This prompted our investigation into dermatology program director (PD) perceptions of DEI programming and its integration into resident selection. A cross-sectional survey of PDs at US dermatology residency programs was conducted from April 2024 to July 2024 (N=30).

Neurodiversity, encompassing conditions such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and dyslexia, represents a significant and often under-recognized segment of the population, including within science, technology, engineering, mathematics, and medicine fields like medicine. Neurodiverse individuals possess unique skills, including enhanced creativity, analytical thinking, and meticulous attention to detail, which are valuable in health care professions. However, failure to recognize and support these individuals can result in missed opportunities, social isolation, and mental health challenges.

Neurodevelopmental impairments associated with congenital heart disease (CHD) may arise from perturbations in brain developmental pathways, including the formation of sulcal patterns. While genetic factors contribute to sulcal features, the association of noncoding variants (ncDNVs) with sulcal patterns in people with CHD remains poorly understood. Leveraging deep learning models, we examined the predicted impact of ncDNVs on gene regulatory signals.

Background: In response to the recent and growing shift from injecting heroin to smoking fentanyl, an increasing number of syringe services programs (SSPs) in the United States are distributing safer smoking supplies. There is a lack of research on whether safer smoking supply distribution is associated with increased SSP engagement and naloxone distribution from SSPs. Therefore, we aimed to assess predictors of safer smoking supply distribution by SSPs and estimate associations between safer smoking supply distribution and scale of harm reduction services.

Introduction: Iron-mediated cell death (ferroptosis) is a proposed mechanism of Alzheimer's disease (AD) pathology. While iron is essential for basic biological functions, its reactivity generates oxidants which contribute to cell damage and death.

Methods: To further resolve mechanisms of iron-mediated toxicity in AD, we analyzed post mortem human brain and ApoEFAD mice.

Clinical Trials in Cancer Theranostics with Potential Near-Term Impact on Clinical Practice.

Br J Radiol

January 2025

Division of Nuclear Medicine and Molecular Imaging Center, Department of Radiology, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

Theranostics has its roots with the first radioiodine therapy for thyroid diseases in about 80 years ago. More recently the field has experienced a remarkable renascence with the regulatory approval of paired imaging and radiopharmaceutical therapy agents in gastroenteropancreatic neuroendocrine tumors and metastatic castration-resistant prostate cancer that are now employed in routine clinical practice. The momentum is strong for identification and testing of new theranostic agents for use in various cancers and finding new clinical incications of the available agents.

Update on Hepatorenal Syndrome: From Pathophysiology to Treatment.

Annu Rev Med

January 2025

Division of Gastrointestinal and Liver Diseases, Department of Medicine, Keck School of Medicine, University of Southern California, Los Angeles, California, USA; email:

Hepatorenal syndrome-acute kidney injury (HRS-AKI) occurs in the setting of advanced chronic liver disease, portal hypertension, and ascites. HRS-AKI is found in ∼20% of patients presenting to the hospital with AKI, but it may coexist with other causes of AKI and/or with preexisting chronic kidney disease, thereby making the diagnosis challenging. Novel biomarkers such as urinary neutrophil gelatinase-associated lipocalin may be useful.
