Association of Physical Activity and Sedentary Behavior With the Risk of Colorectal Cancer.
Although recent evidence supports that prolonged sedentary behavior and reduced physical activity are associated with colorectal cancer risk, there are few studies analyzing the colorectal cancer risk according to different types of physical activity and combined effects of sedentary behavior and physical activity on colorectal cancer. This study aimed to investigate the association of sedentary behavior and physical activity with colorectal cancer. ⋯ This study found that sedentary behavior was significantly associated with the increased risk of colorectal cancer. Moreover, sedentary behavior without physical activity increased the risk of colorectal cancer. Reducing sedentary behavior and recommending any type of physical activity may reduce the risk of colorectal cancer.

Diagnostic Value of Anti-Nuclear Antibodies: Results From Korean University-Affiliated Hospitals.
Unnecessary and inappropriate laboratory testing accounts for a significant portion of waste in health care utilization. The aim of this study was to examine the diagnostic value of the anti-nuclear antibody (ANA) test by examining the rate of ANA associated rheumatic disease (AARD) diagnosis among ANA tested and ANA positive subjects and positive predictive value (PPV) of ANA test leading to AARD diagnosis in different ANA titers and different subsets of patients in 5 hospitals affiliated with a university. ⋯ AARD was diagnosed in less than 1% of all ANA tested patients in university-affiliated hospitals. This result shows that careful consideration before ordering the screening ANA is needed to improve the utility of the test for providers and patients and to reduce health costs spurred by unnecessary testing and its consequences.

The Impact of the Amendment of the Health Insurance Coverage for F-18 Fluorodeoxyglucose Positron Emission Tomography on the Healthcare Behaviors for Breast Cancer: An Interrupted Time Series Analysis of the Korean National Data From 2013 to 2018.
F-18 Fluorodeoxyglucose positron emission tomography (F-18 FDG PET), which can cover the body from the skull base to the thigh in one scan, is beneficial for evaluating distant metastasis. F-18 FDG PET has interested policymakers because of its relatively high cost. This study investigated the effect of the F-18 FDG PET reimbursement criteria amendment on healthcare behavior in breast cancer using an interrupted time series (ITS) analysis. ⋯ Restriction of health insurance coverage for cancer may affect healthcare behaviors. To compensate for it, the policymakers must consider this and anticipate the impact following implementation.
