Objective: This study aimed to determine whether race modifies the association between obesity and cancer death.
Methods: The Pennington Center Longitudinal Study included 18,296 adults; 35.0% were male and 34.3% were Black. The primary end point was death from cancer.
Results: During a follow-up of 14.3 years, 346 cancer deaths occurred. Among men, race modified the association of BMI and cancer death (p = 0.045); compared with a BMI of 22 kg/m , a BMI of 35 in White men was associated with a hazard ratio of 1.74 (95% CI: 1.38-2.21), and in Black men, the hazard ratio was 0.64 (95% CI: 0.45-0.90). Among women, race did not modify the association of BMI and cancer death (p =0.43); however, compared with a BMI of 22, a BMI of 35 in White women was associated with a hazard ratio of 1.42 (95% CI: 1.18-1.70) and in Black women, the hazard ratio was 0.99 (95% CI: 0.82-1.20).
Conclusions: In this diverse cohort of adults, having obesity was associated with an increased risk of cancer death in White men and women. In contrast, having obesity was associated with a reduced risk of cancer death in Black men and did not influence risk in Black women.

Background: Some types of cancer have been associated with reduced risk of clinical dementia diagnosis. Whether cancer history may be associated with neuropathological features of neurodegeneration or cerebrovascular disease is not well understood. We investigated the relation between cancer diagnosis and brain pathology in a sample of community-based research volunteers enrolled in an Alzheimer's Disease Research Center (ADRC) cohort.

Cardiovascular-kidney-metabolic (CKM) syndrome is the association between obesity, diabetes, CKD (chronic kidney disease), and cardiovascular disease. GDF-15 mainly acts through the GFRAL (Glial cell line-derived neurotrophic factor Family Receptor Alpha-Like) receptor. GDF-15 and GDFRAL complex act mainly through RET co-receptors, further activating Ras and phosphatidylinositol-3-kinase (PI3K)/Akt pathways through downstream signaling.

The 5,000 to 8,000 monogenic diseases are inherited disorders leading to mutations in a single gene. These diseases usually appear in childhood and sometimes lead to morbidity or premature death. Although treatments for such diseases exist, gene therapy is considered an effective and targeted method and has been used in clinics for monogenic diseases since 1989.

Introduction: Iron oxide nanozyme was synthesized from the fruit peel extract of pomegranate, which served as a reducing agent during the green synthesis. The scavenging of reactive oxygen species is often accompanied by immunomodulation following antiproliferative effects due to the crosstalk between the proteins involved in the inter-related signaling pathways.
Method: In the current study, the green synthesized nanozyme was studied for its ability to induce apoptosis in breast cancer cell lines.

Pancreatic ductal adenocarcinoma (PDAC) is the deadliest malignant tumor, with a grim 5-year overall survival rate of about 12%. As its incidence and mortality rates rise, it is likely to become the second-leading cause of cancer-related death. The radiological assessment determined the stage and management of PDAC.
