Several studies have reported the preventive effect of metformin on cancer development. This study aimed to investigate the relationship between use of metformin and risk of cancer in Koreans.. ..A total of 323,430 subjects was enrolled (301,905 individuals without diabetes [No DM], 8,643 diabetic patients with metformin treatment [metformin users], and 12,882 diabetic patients without… Continue reading #Metformin users with diabetes and individuals without #diabetes were at lower risk of overall cancer incidence than metformin non-users with diabetes based on the Korean NHIS-HEALS cohort

Serum #iodine and #breast cancer risk: A prospective nested case-control study stratified for selenium levels
Iodine has been suggested to protect against breast cancer, but there are no epidemiological studies on individual risk. An interesting finding is that in areas where the exposure to both selenium and iodine are high (e.g. Japan), the risk of breast cancer is lower than in areas where selenium is high and iodine low (e.g.… Continue reading Serum #iodine and #breast cancer risk: A prospective nested case-control study stratified for selenium levels
Fine Particulate Matter Air #Pollution and Mortality among Pediatric, Adolescent, and Young Adult Cancer Patients
Air pollution is a carcinogen and causes pulmonary and cardiac complications. We examined the association of fine particulate matter pollution (PM2.5) and mortality from cancer and all causes among pediatric, adolescent, and young adult (AYA) patients with cancer in Utah, a state with considerable variation in PM2.5.. ..Increases in PM2.5 per 5 μg/m3 were associated… Continue reading Fine Particulate Matter Air #Pollution and Mortality among Pediatric, Adolescent, and Young Adult Cancer Patients
Dietary Intake of #Acrylamide and Risk of Breast, Endometrial, and Ovarian Cancers: A Systematic Review and Dose–Response Meta-analysis
Acrylamide is a probable human carcinogen. Aside from occupational exposures and smoking, diet is the main source of exposure in humans. We performed a systematic review of the association between estimated dietary intake of acrylamide and risk of female breast, endometrial, and ovarian cancers in nonexperimental studies published through February 25, 2020, and conducted a… Continue reading Dietary Intake of #Acrylamide and Risk of Breast, Endometrial, and Ovarian Cancers: A Systematic Review and Dose–Response Meta-analysis
Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40… Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
Little is known about the role of low‐carbohydrate diets (LCDs) in the development of hepatocellular carcinoma (HCC).. ..During 3,664,769 person years of follow‐up, there were 156 incident HCC cases. Although there were no associations between overall or animal‐based LCD score and risk of HCC, plant‐based LCD score was inversely associated with HCC risk (HR: 0.83;… Continue reading Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling
..Using one defined anaerobic gut microbiota to track whether microbiota interact with host immunity, we observed that Bifidobacterium facilitates local anti-CD47 immunotherapy on tumor tissues through the capacity to accumulate within the tumor microenvironment. Systemic administration of Bifidobacterium leads to its accumulation within the tumor and converts the nonresponder mice into responders to anti-CD47 immunotherapy… Continue reading Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling
CDC Colorectal Cancer Screening Test Use
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States of cancers that affect both men and women. Despite strong evidence that screening for CRC reduces incidence and mortality, CRC screening prevalence is below the national target. This report describes current CRC screening prevalence by age, various demographic factors, and… Continue reading CDC Colorectal Cancer Screening Test Use
#Statin-induced GGPP depletion blocks macropinocytosis and starves cells with oncogenic defects
Our studies establish a connection between two isolated observations that 1) statins, taken by millions to lower cholesterol, have antitumor activity and 2) Ras-induced macropinocytosis is important in tumorigenesis. We discover that by depleting GGPP required for pseudopod extension and macropinocytosis, statins selectively kill cells with oncogenic defects by limiting nutrient uptake. https://bit.ly/2wT1ypw
