AIMS: The study assesses the reliability of fr-AGILE, a validated rapid tool used for the evaluation of multidimensional frailty in older adults hospitalized with COVID-19. METHODS: Two different staff members independently assessed the presence of frailty in 144 patients aged ≥ 65 years affected by COVID-19 using the fr-AGILE tool. The internal consistency of fr-AGILE was evaluated by examining the item-total correlations and the Kuder-Richardson (KR) formula. The inter-rater reliability was evaluated using linear weighted kappa. RESULTS: Multidimensional frailty severity increases with age and is associated to higher use of non-invasive ventilation (p = 0.025), total severity score on chest tomography (p = 0.001) and in-hospital mortality (p = 0.032). Fr-AGILE showed good internal consistency (KR-20 = 0.742) and excellent inter-rater reliability (weighted kappa = 0.752 and 0.878 for frailty score and frailty degree, respectively). CONCLUSIONS: fr-AGILE tool can quickly identify and quantify multidimensional frailty in hospital settings for older patient affected by COVID-19.

Frailty affects the physical, cognitive, and social domains exposing older adults to an increased risk of cardiovascular disease and death. The mechanisms linking frailty and cardiovascular outcomes are mostly unknown. Here, we studied the association of abundance (flow cytometry) and gene expression profile (RNAseq) of stem/progenitor cells (HSPCs) and molecular markers of inflammaging (ELISA) with the cardiorespiratory phenotype and prospective adverse events of individuals classified according to levels of frailty. Two cohorts of older adults were enrolled in the study. In a cohort of pre-frail 35 individuals (average age: 75 years), a physical frailty score above the median identified subjects with initial alterations in cardiorespiratory function. RNA sequencing revealed S100A8/A9 upregulation in HSPCs from the bone marrow (>10-fold) and peripheral blood (>200-fold) of individuals with greater physical frailty. Moreover higher frailty was associated with increased alarmins S100A8/A9 and inflammatory cytokines in peripheral blood. We then studied a cohort of 104 more frail individuals (average age: 81 years) with multidomain health deficits. Reduced levels of circulating HSPCs and increased S100A8/A9 concentrations were independently associated with the frailty index. Remarkably, low HSPCs and high S100A8/A9 simultaneously predicted major adverse cardiovascular events at 1-year follow-up after adjustment for age and frailty index. In conclusion, inflammaging characterized by alarmin and pro-inflammatory cytokines in pre-frail individuals is mirrored by the pauperization of HSPCs in frail older people with comorbidities. S100A8/A9 is upregulated within HSPCs, identifying a phenotype that associates with poor cardiovascular outcomes.

BACKGROUND: The COVID-19 pandemic represents one of the most massive health emergencies in the last century and has caused millions of deaths worldwide and a massive economic and social burden. The aim of this study was to evaluate how the COVID-19 pandemic-during the Italian lockdown period between 8 March and 4 May 2020-influenced orthopaedic access for traumatic events to the Emergency Department (ER). METHODS: A retrospective review of the admission to the emergency room and the discharge of the trauma patients' records was performed during the period between 8 March and 4 May 2020 (block in Italy), compared to the same period of the previous year (2019). Patients accesses, admissions, days of hospitalisation, frequency, fracture site, number and type of surgery, the time between admission and surgery, days of hospitalisation, and treatment cost according to the diagnosis-related group were collected. Chi-Square and ANOVA test were used to compare the groups. RESULTS: No significant statistical difference was found for the number of emergency room visits and orthopaedic hospitalisations (p < 0.53) between the year 2019 (9.5%) and 2020 (10.81%). The total number of surgeries in 2019 was 119, while in 2020, this was just 48 (p < 0.48). A significant decrease in the mean cost of orthopaedic hospitalisations was detected in 2020 compared (261.431 euros, equal to - 52.07%) relative to the same period in 2019 (p = 0.005). Although all the surgical performances have suffered a major decline, the most frequent surgery in 2020 was intramedullary femoral nailing. CONCLUSION: We detected a decrease in traumatic occasions during the lockdown period, with a decrease in fractures in each district and a consequent decrease in the diagnosis-related group (DRG).
