Purpose: Concerns about falling (CaF) are common in older adults. They are associated with increased risk of falls, activity restriction, social isolation, and physical deconditioning. This systematic review assessed if frailty is a risk factor for CaF.
Methods: Searches of cross-sectional and prospective studies exploring associations between frailty and CaF were conducted across five databases (Medline, CINAHL, Embase, Psychinfo and Scopus). The Risk of Bias in Non-randomised Studies of Exposure (ROBINS-E) was used to determine risk of bias.
Results: The search identified 2492 articles, 12 were included for data extraction: 8 cross-sectional and 4 prospective studies. Participants' mean ages across the different studies ranged from 67.5 - 81.7 years. All adjusted analyses reported a significant association between increasing frailty and CaF, except for one cross-sectional paper. Significant adjusted Odd Ratios (ORs) ranged from 1.79 (CI = 1.18-2.71) to 144.78 (CI = 13.86 - 1512.60) for cross-sectional studies, and from 1.33 (CI = 1.04-1.69) to 12.4 (CI = 7.6-20.1) for prospective studies. Three studies (one cross-sectional and two prospective) explored the association between frailty and concern-related activity restriction: A significant association was reported in two prospective studies (adjusted OR = 1.58 (CI=1.09-2.30) and adjusted RRR = 3.91 (2.61-5.85)), but not the cross-sectional study (adjusted OR = 1.31 (CI=0.62-2.78)).
Conclusion: This review identifies strong associations between increasing frailty and both CaF and associated activity restriction. This expands previous work describing the opposite association (that CaF can lead to frailty), suggesting a bi-directional relationship. Clinicians working with pre-frail and frail older adults should consider screening for CaF.

Background: Developing interventions along with the population of interest using systems thinking is a promising method to address the underlying system dynamics of overweight. The purpose of this study is twofold: to gain insight into the perspectives of adolescents regarding: (1) the system dynamics of energy balance-related behaviours (EBRBs) (physical activity, screen use, sleep behaviour and dietary behaviour); and (2) underlying mechanisms and overarching drivers of unhealthy EBRBs.
Methods: We conducted Participatory Action Research (PAR) to map the system dynamics of EBRBs together with adolescents aged 10-14 years old living in a lower socioeconomic, ethnically diverse neighbourhood in Amsterdam East, the Netherlands.
Positive feedback loop involving AMPK and CLYBL acetylation links metabolic rewiring and inflammatory responses.

Metabolic rewiring underlies effective macrophages defense to respond disease microenvironment. However, the underlying mechanisms driving metabolic rewiring to enhance macrophage effector functions remain unclear. Here, we demonstrated that the metabolic reprogramming in inflammatory macrophages depended on the acetylation of CLYBL, a citramalyl-CoA lyase, at lysine 154 (K154), and blocking CLYBL-K154 acetylation restricted the release of pro-inflammatory factors.

Cellulose composites have exceptional qualities, particularly in removing heavy metal ions. Nevertheless, these materials' poor mechanical qualities and the restricted exposure of surface-active sites reduce the effectiveness of their removal. The removal efficiency of adsorbent materials largely depends on their macroscopic structural characteristics.

The limited solubility, rapid metabolism, and poor bioavailability of curcumin restrict its application. In this study, we synthesized chickpea protein isolate (CPI)-citrus pectin (CP) conjugates to prepare an emulsion delivery system that enhances the stability and bioavailability of curcumin. The CPI-CP emulsion achieved a curcumin encapsulation efficiency of 86.
