Importance: Health disparities among racial and ethnic minoritized populations, particularly for cancer mortality rates, remain a major public health concern. Men from underrepresented backgrounds (Black and Hispanic men, specifically) face the pervasive effects of discrimination in their daily lives, which also contribute to the complex associations among allostatic load (a marker of chronic stress), educational opportunities, and elevated risks of cancer mortality.

Objective: To elucidate the associations among educational attainment, allostatic load, and cancer mortality risk among men.

Article Synopsis
  • * Results showed women had higher levels of AEA, and obese participants had more PEA, while asymptomatic controls had lower AEA compared to those with pancreatic diseases.
  • * Additionally, individuals with acute pancreatitis had the highest AEA levels, but lower 2-AG levels were found in those with recent abdominal pain; these findings suggest potential therapeutic targets related to cannabinoid receptors in managing pancreatitis.

Objectives: Chronic pancreatitis (CP) is an inflammatory disease affecting the absorption of fat-soluble nutrients. Signaling in pancreatic cells that lead to inflammation may be influenced by fatty acids (FAs) through diet and de novo lipogenesis. Here, we investigated the relationship between plasma FA composition in CP with heterogeneity of etiology and complications of CP.

Article Synopsis
  • Chronic pancreatitis (CP) often leads to chronic abdominal pain, with a significant number of patients relying on opioids for pain management, despite challenges like opioid-induced hyperalgesia.
  • This phase 1 trial aims to evaluate the safety and tolerability of combining lacosamide, an antiseizure drug, with opioids for better pain control in patients with CP.
  • The study follows a dose-escalation design and plans to enroll between 12 to 24 participants, with findings expected to be published by March 2025.

Introduction: Chronic pancreatitis (CP) is a progressive fibroinflammatory disorder lacking therapies and biomarkers. Neutrophil gelatinase-associated lipocalin (NGAL) is a proinflammatory cytokine elevated during inflammation that binds fatty acids (FAs) such as linoleic acid. We hypothesized that systemic NGAL could serve as a biomarker for CP and, with FAs, provide insights into inflammatory and metabolic alterations.

Patients with chronic pancreatitis (CP) are particularly vulnerable to nutrient malabsorption and undernutrition caused by the underlying pathology of their disease. Dietary intervention trials involving soy isoflavones in patients with CP are limited and isoflavone metabolites have not yet been reported. We hypothesized soy bread containing plant-based protein, dietary fiber, and isoflavones would be well-tolerated and restore gut functional capacity which would lead to isoflavone metabolites profiles like those of healthy populations.
