    Cognitive impairment is correlated with physical function. However, the results in the literature are inconsistent with cognitive and physical performance measures. Thus, the aim of this study was to determine the association between cognitive performance and physical function among older adults.

    Background: Various interventions have been tested as primary prevention of colorectal cancers (CRC), but comprehensive evidence comparing them is absent. We examined the effects of various chemopreventive agents (CPAs) on CRC incidence and mortality.

    Methods: We did a network meta-analysis based on a systematic review of randomized controlled trials (RCTs) that compared at least one CPA (aspirin, antioxidants, folic acid, vitamin B6, vitamin B12, calcium, vitamin D, alone or in combination) to placebo or other CPA in persons without history of CRC. Several databases were searched from inception up to March 2017. Primary outcomes were early and long-term CRC incidence and mortality.

    Results: Twenty-one RCTs comprising 281,063 participants, 9 RCTS comprising 160,101 participants, and 7 RCTs comprising 24,001 participants were included in the network meta-analysis for early risk of CRC incidence, long-term risk of CRC incidence and mortality, respectively. For early CRC incidence, no CPAs were found to be effective. For long-term CRC incidence and mortality, aspirin was the only intervention that showed protective effects with potential dose-dependent effects (risk ratio [RR], 0.74 [95% CI, 0.57-0.97] for high-dose [≥325 mg/day] and RR, 0.81 [95% CI, 0.67-0.98] for very-low-dose [≤100 mg/day]). Similar trend was found for mortality (RR, 0.43 [95% CI, 0.23-0.81] for low-dose [>100-325 mg/day] and RR, 0.65 [95% CI, 0.45-0.94] for very-low-dose). However, in net clinical benefit analysis, when combining risk estimates on mortality from CRC, cardiovascular disease, and pooled risk estimates of major gastrointestinal bleeding, low-dose aspirin provided the highest net survival gain (%) of 1.736 [95% CI, 1.010-2.434].

    Conclusion: Aspirin at the dose range of 75-325 mg/day is a safe and effective primary prevention for long-term CRC among people at average risk. None of the other CPAs were found to be effective. There may potentially be differential effects among various doses of aspirin that needs further investigation.

    Background: Acute myocardial infarction (AMI) management strategies, involving treatment and post-care, are much more difficult for patients with dementia. This study investigated the factors influencing the use of invasive procedures and long-term care in the management strategies for AMI patients with dementia and the factors associated with these patients' survival.

    Methods: This multilevel study combined information from two databases, namely later-stage elderly healthcare insurance and long-term care insurance claims, from 2013 to 2019. Of 214,963 individuals with dementia, we identified 13,593 patients with AMI. The primary outcomes were the use of invasive procedures for treatment and long-term care for post-care management. Survival outcomes were also measured over a 6-year period, adjusting for individual- and regional-level characteristics in multilevel models.

    Results: A total of 1954 (14.38%) individuals received an invasive procedure during treatment, and 7850 (87.18%) used long-term care for post-care management after AMI. After multivariate adjustment, patients aged ≥ 85 years and women were less likely to receive invasive procedures and more likely to use long-term care. Patients undergoing invasive procedures had a lower use of long-term care. Better survival outcome was significantly associated with invasive management and long-term care, regardless of the type of care.

    Conclusion: Age and sex determine the use of invasive procedures and long-term care after AMI among patients with dementia. AMI patients with dementia receiving invasive procedures and long-term care had better survival outcomes.
