Metformin and other anti‐diabetic medication use and breast cancer incidence in the Nurses' Health Studies

Tengteng Wang, Boyang Chai, Wendy Y. Chen, Michelle D. Holmes, more

International Journal of Cancer > 155 > 2 > 211 - 225

We aimed to examine the association between the use of metformin and other anti‐diabetic medications and breast cancer incidence within two large prospective cohort studies. We followed 185,181 women who participated in the Nurses' Health Study (NHS; 1994–2016) and the NHSII (1995–2017), with baseline corresponding to the date metformin was approved for type 2 diabetes (T2D) treatment in the US Information...

Parity, breastfeeding, and breast cancer risk by hormone receptor status and molecular phenotype: results from the Nurses’ Health Studies

Renée T. Fortner, Julia Sisti, Boyang Chai, Laura C. Collins, more

Breast Cancer Research > 2019 > 21 > 1 > 1-9

Background Epidemiologic data suggest that parity increases risk of hormone receptor-negative breast cancer and that breastfeeding attenuates this association. Prospective data, particularly on the joint effects of higher parity and breastfeeding, are limited. Methods We investigated parity, breastfeeding, and breast cancer risk by hormone-receptor (estrogen (ER) and progesterone receptor (PR))...

Erythrocyte membrane fatty acids and breast cancer risk: a prospective analysis in the nurses' health study II

Kelly A. Hirko, Boyang Chai, Donna Spiegelman, Hannia Campos, more

International Journal of Cancer > 142 > 6 > 1116 - 1129

The roles of specific fatty acids in breast cancer etiology are unclear, particularly among premenopausal women. We examined 34 individual fatty acids, measured in blood erythrocytes collected between 1996 and 1999, and breast cancer risk in a nested case‐control study of primarily premenopausal women in the Nurses' Health Study II. Breast cancer cases diagnosed after blood collection and before June...

Abrupt Decline in Kidney Function Before Initiating Hemodialysis and All-Cause Mortality: The Chronic Renal Insufficiency Cohort (CRIC) Study

Raymond K. Hsu, Boyang Chai, Jason A. Roy, Amanda H. Anderson, more

American Journal of Kidney Diseases > 2016 > 68 > 2 > 193-202

It is not clear whether the pattern of kidney function decline in patients with chronic kidney disease (CKD) may relate to outcomes after reaching end-stage renal disease (ESRD). We hypothesize that an abrupt decline in kidney function prior to ESRD predicts early death after initiating maintenance hemodialysis therapy.Prospective cohort study.The Chronic Renal Insufficiency Cohort (CRIC) Study enrolled...

Relation of Aortic Valve Calcium to Chronic Kidney Disease (from the Chronic Renal Insufficiency Cohort Study)

Marie A. Guerraty, Boyang Chai, Jesse Y. Hsu, Akinlolu O. Ojo, more

The American Journal of Cardiology > 2015 > 115 > 9 > 1281-1286

Although subjects with chronic kidney disease (CKD) are at markedly increased risk for cardiovascular mortality, the relation between CKD and aortic valve calcification has not been fully elucidated. Also, few data are available on the relation of aortic valve calcification and earlier stages of CKD. We sought to assess the relation of aortic valve calcium (AVC) with estimated glomerular filtration...
