Clinical interventions in aging
-
Age-associated brain physiologic decline and reduced mobility are key elements of increased age-associated vulnerability. ⋯ Frailty is highly prevalent and strongly associated with cognitive impairment and depression in older Chileans. The risk for death was higher for frail people, but underlying cognitive impairment is a key component of the lower survival rate.

Polypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. The purpose of the study was to investigate the prevalence of PIMs identified by the Beers 2015 and 2012 criteria in older patients in China and identify the correlates of PIMs. ⋯ Our study showed a high prevalence of PIM use in China, which was associated with various correlates. The Beers 2015 criteria detected significantly more PIMs than the 2012 criteria due to the inclusion of PPIs.

The study of frailty is important to identify the additional needs of medical long-term care and prevent adverse outcomes in community dwelling older adults. This study aimed to determine the prevalence of frailty and its association with adverse outcomes in community dwelling older adults. ⋯ Approximately 2 out of 10 older adults demonstrate frailty. This is associated with limitations in ADL, falls, and admission to emergency rooms during the previous year as well as low quality of life.

The aim of this study was to explore the prognostic impact of clinical factors on the short-term outcomes of renal function (RF) in very elderly patients with acute kidney injury (AKI). ⋯ Risk factors for the poor outcomes of RF in very elderly patients with AKI were BMI, baseline eGFR, low MAP, low prealbumin level, hypoalbuminemia, oliguria, BUN level, and more severe AKI stage. Identifying risk factors may help to improve patient outcomes.

Meta Analysis
Association between apolipoprotein E gene polymorphism and mild cognitive impairment: a meta-analysis.
A number of published case-control studies reported that the apolipoprotein E (ApoE) gene polymorphism was associated with the mild cognitive impairment (MCI). However, previous reports still remain conflicting. To estimate the association between ApoE polymorphism and MCI susceptibility, we searched the electronic databases including PubMed, Wanfang, CNKI (China National Knowledge Infrastructure), VIP, and EMBASE to retrieve all available studies. ⋯ In the stratified analysis based on ethnicity, similar results were also observed in Chinese population (significant risk: ε4 vs ε3: OR =2.52, 95% CI: 2.19-2.90; ε4/ε4 vs ε3/ε3: OR =5.45, 95% CI: 3.41-8.70; ε2/ε4 vs ε3/ε3: OR =2.59, 95% CI: 1.74-3.86; ε3/ε4 vs ε3/ε3: OR =2.34, 95% CI: 1.97-2.79; slight protection: ε2/ε3 vs ε3/ε3: OR =0.79, 95% CI: 0.64-0.98; no association: ε2 vs ε3: OR =0.92, 95% CI: 0.78-1.09; and ε2/ε2 vs ε3/ε3: OR =1.04, 95% CI: 0.55-1.99). In summary, this meta-analysis of 5,709 subjects suggested that ApoE ε4 allele was associated with an increased risk of MCI. In addition, ApoE ε2/ε3 genotype provided a slight protection for MCI.
