ABSTRACT
Background: The C-reactive protein-albumin-lymphocyte (CALLY) index is a novel inflammatory biomarker, and its association with the prognosis of coronary artery disease (CAD) after percutaneous coronary intervention (PCI) has not previously been studied. Therefore, this study aimed to investigate the effect of using the CALLY index on adverse outcomes in CAD patients undergoing PCI. Methods: From December 2016 to October 2021, we consecutively enrolled 15,250 CAD patients and performed follow-ups for primary endpoints consisting of all-cause mortality (ACM) and cardiac mortality (CM). The CALLY index was computed using the following formula: (albumin × lymphocyte)/(C-reactive protein (CRP) × 10 4 ). The average duration of the follow-up was 24 months. Results: A total of 3799 CAD patients who had undergone PCI were ultimately enrolled in the present study. The patients were divided into four groups according to the CALLY index quartiles: Q1 ( ≤ 0.69, n = 950), Q2 (0.69-2.44, n = 950), Q3 (2.44-9.52, n = 950), and Q4 ( > 9.52, n = 949). The low-Q1 group had a significantly higher prevalence of ACM (p < 0.001), CM (p < 0.001), major adverse cardiac events (MACEs) (p = 0.002), and major adverse cardiac and cerebrovascular events (MACCEs) (p = 0.002). Kaplan-Meier analysis revealed that a low CALLY index was significantly linked with adverse outcomes. After univariate and multivariate Cox regression analysis, the risk of ACM, CM, MACEs, and MACCEs decreased by 73.7% (adjust hazard risk [HR] = 0.263, 95% CI: 0.147-0.468, p < 0.001), 70.6% (adjust HR = 0.294, 95% CI: 0.150-0.579, p < 0. 001), 37.4% (adjust HR = 0.626, 95% CI: 0.422-0.929, p = 0.010), and 41.5% (adjust HR = 0.585, 95% CI: 0.401-0.856, p = 0.006), respectively, in the Q4 quartiles compared with the Q1 quartiles. Conclusions: This study revealed that a decreased CALLY index was associated with worse prognoses for CAD patients after PCI. The categorization of patients with a decreased CALLY index could provide valuable evidence for the risk stratification of adverse outcomes in CAD patients after PCI.

ABSTRACT
Older people often face varied and vicious abuse from care workers. Situations are often more pronounced for older people who live with additional cognitive or physical difficulties, such as dementia and disabilities, the prevalence of which has been on the rise in China and elsewhere. Recent discoveries of elderly abuse in China, which span from alarming levels of verbal, physical, psychological, financial, to sexual abuse, are all caused by nannies or "bao mu". Different from Western countries, the word nanny is often used to refer to people who offer caregiving help in residential settings at large, regardless of the age of the care recipients. What is also different is the lack of regulations or even rigorous training and evaluation processes for nannies in China: almost anyone could become a nanny-even though a background check is often required for nannies, this process is often highly variable and dependent on the specific labour agencies that nannies are registered with. Yet without structured studies and systematic data, little is known about the extent and severity of nanny-induced elderly abuse in China. To this end, this paper aims to discuss the unique elderly care environment-such as the "721 Rule"-in China, particularly in the post-COVID era, and highlight the critical need for timely and rigorous studies on the potential prevalence and severity of nannies' abuse and neglect of older people.
