Eating frequency, timing of meals, and sleep duration before and after a randomized controlled weight loss trial for breast cancer survivors.

Purpose: To examine eating frequency, timing of meals, and sleep duration before and after a weight loss intervention for breast cancer survivors.

Methods: Female breast cancer survivors (n = 159; 55 ± 9 years; 31.4 ± 5.

Use of an emulated trial to investigate the association between use of nitrogen-based bisphosphonates and risk of epithelial ovarian cancer.

Background: Epithelial ovarian cancer (EOC) is the eighth most common cancer in women, with poor survival outcomes. Observational evidence suggests that nitrogen-based bisphosphonate (NBB) use may be associated with reduced risk of EOC, particularly the endometrioid and serous histotypes; however, confounding by indication is a concern. An alternative approach to investigate the chemo-preventive potential of NBBs is to emulate a target trial by identifying all women who initiate use of NBBs and investigate the risk of EOC for continued users compared with discontinued users.

Peripheral intravenous catheter material and design to reduce device failure: A systematic review and meta-analysis.

Background: Patients require vascular access for medical treatments, diagnostic procedures and symptom management. Current failure rates of peripheral intravascular catheters (PIVCs) are unacceptably high (40-50%). This systematic review aimed to determine the effect of different PIVC materials and designs on the incidence of PIVC failure.
