Objectives: Diet can modulate systemic inflammation, while inflammation is a critical contributory factor of frailty. However, longitudinal data on the association between dietary inflammatory index (DII) and frailty are limited, and the intermediate mechanisms remain unclear. This study aimed to examine the association between DII and incident frailty and the potential mediating roles of frailty-related biomarkers.

Design: Prospective cohort study.

Setting: The Mr. OS and Ms. OS (Hong Kong) study.

Participants: A total of 3,035 community-dwelling men and women aged above 65 years without frailty at baseline were included.

Measurements: DII scores were calculated using the locally validated food frequency questionnaire. Incident frailty at year four was defined using the Fried frailty phenotype. Logistic regression was used to examine the association between DII and frailty onset. Mediation analysis was used to explore the mediating roles of frailty-related biomarkers in the DII-frailty association.

Results: During four years of follow-up, 208 individuals developed frailty. Compared with the lowest tertile of DII, the highest tertile was associated with an increased risk of incident frailty (OR: 1.82; 95% CI: 1.17-2.82; p = 0.008) after adjustment for relevant confounders. The DII-frailty association was significant in men but not in women. Furthermore, increasing serum homocysteine, decreasing serum folate, and reducing estimated glomerular filtration rate (eGFR) mediated 11.6%, 7.1%, and 9.6 % of the total relation between DII and frailty onset, respectively.

Conclusion: In this cohort study, a pro-inflammatory diet was associated with a higher risk of frailty onset, mediated by homocysteine, folate, and renal function.

Introduction: In the past, certain oncological therapies were not offered to frail older patients. However, the advancement of geriatric oncology, tailored chemotherapy regimens, the introduction of new treatments, and the optimization of supportive care have contributed to enhancing the therapeutic margin. We aimed to evaluate the benefit of systemic treatment among older adults by assessing the three-month survival of older frail patients with metastatic cancer.

Biomarkers of ageing serve as important outcome measures in longevity-promoting interventions. However, there is limited consensus on which specific biomarkers are most appropriate for human intervention studies. This work aimed to address this need by establishing an expert consensus on biomarkers of ageing for use in intervention studies via the Delphi method.

Is there an optimal perioperative risk assessment tool for older adult ankle fractures?

Arch Orthop Trauma Surg

December 2024

Department of Orthopaedic Surgery and Rehabilitation, Loyola University Medical Center, 2160 S First Ave, Maywood, IL, 60153, USA.

Objective: To measure the predictive value of three perioperative risk assessment tools (National Surgical Quality Improvement Program-NSQIP, Modified 5-factor Frailty Index-mFI-5, and Score for Trauma Triage in Geriatric and Middle Aged-STTGMA) in predicting postoperative complications in older adult ankle fractures.

Materials And Methods: This is a retrospective study of surgically treated isolated older adult ankle fractures at an academic center between 2007 and 2022. Exclusion criteria included age < 55 years, presence of pathologic fractures, and having multiple orthopaedic injuries.

Background: Low-gradient (LG) aortic stenosis (AS) has not been fully characterized compared with high-gradient (HG) AS in terms of cardiac damage, frailty, aortic valve calcification, and clinical outcomes.

Objectives: The aim of this study was to compare the clinical characteristics and outcomes between each hemodynamic type of LG AS and HG AS.

Methods: The current study included 3,363 patients in the CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) Registry-2 after excluding patients without indexed stroke volume or left ventricular ejection fraction (LVEF) data.

Background: Exposure to high anticholinergic burden is associated with adverse outcomes in older adults. Older adults with frailty have greater vulnerability to adverse anticholinergic effects. There is limited data on anticholinergic burden in hospitalised older adults with frailty particularly, in New Zealand.
