Importance: Women with a history of breast cancer (BC) experience greater physical health decline compared with age-matched women without cancer. However, whether this decline differs in patients who received chemotherapy and endocrine therapy is not well understood.
Objective: To investigate physical health decline in BC survivors who received chemotherapy or endocrine therapy compared with age-matched women without cancer.
Purpose: This paper describes the data collection and management methods for the Cancer Prevention Study-3 (CPS-3) Accelerometry Substudy, a nested cohort of device-based physical activity and sedentary time data.
Participants: US-based CPS-3 participants (initially enrolled 2006-2013) who completed the 2018 follow-up survey and had a valid email address were invited to the Accelerometry Substudy (n=109 780). Among the 23 111 participants who registered and were shipped an ActiGraph GT3X+ accelerometer, 21 219 participants returned the device with a complete wear log (91.
All states in the United States now have a well-established cancer registry. Linkage with these registries may be a cost-effective method of follow-up for cancer incidence in multistate cohort studies. However, the sensitivity of linkage with the current network of state registries for detecting incident cancer diagnoses within cohort studies is not well-documented.

Methods: The American Cancer Society (ACS) recruited a new prospective cohort study, Cancer Prevention Study 3 (CPS-3), between 2006 and 2013 from 35 states and Puerto Rico. Enrollment took place primarily at ACS community events and at community enrollment "drives.
Microsatellites are useful tools for ecologists and conservationist biologists, but are taxa-specific and traditionally expensive and time-consuming to develop. New methods using next-generation sequencing (NGS) have reduced these problems, but the plethora of software available for processing NGS data may cause confusion and difficulty for researchers new to the field of bioinformatics. We developed a bioinformatics pipeline for microsatellite development from Illumina paired-end sequences, which is packaged in the open-source bioinformatics tool Galaxy.

Background: Hypermobility or instability of the first metatarsal is associated with increased hallux valgus deformity and greater risk of recurrence after surgery. The objective of this in vitro study was to determine the ranges of movement, under directional loading, of the normal first metatarsal and the effect of the longitudinal plantar aponeurosis and the transverse tie-bar ligamentous system.
Methods: A model has been developed to quantify the influence of the first intermetatarsal ligament and plantar aponeurosis on movements of the first metatarsal.
Some epidemiologic studies suggest that use of vitamin C or vitamin E supplements, both potent antioxidants, may reduce the risk of bladder cancer. The authors examined the association between use of individual vitamin C and vitamin E supplements and bladder cancer mortality among 991,522 US adults in the Cancer Prevention Study II (CPS-II) cohort. CPS-II participants completed a self-administered questionnaire at enrollment in 1982 and were followed regarding mortality through 1998.
