RESUMO

BACKGROUND: Heterozygous isocitrate dehydrogenase (IDH) mutations occur in about half of conventional central bone chondrosarcomas (CCBC). Aim of this study was to assess the frequency and prognostic impact of IDH mutations in high grade CCBC patients. METHODS: 64 patients with G2 and G3 CCBC were included. DNA extraction, PCR amplification of IDH1/2 exon 4s, and sequencing analysis with Sanger were performed. RESULTS: IDH mutations were detected in 24/54 patients (44%): IDH1 in 18, IDH2 in 4, and both IDH1/2 in 2 patients. The frequency of mutations was 37% in G2 vs. 69% in G3 (p = 0.039), and 100% in three Ollier disease associated chondrosarcoma. 5-year overall survival (OS) at 124 months (range 1-166) was 51%, with no significant difference based on the IDH mutational status: 61% in IDHmut vs. 44% in IDH wild type (IDHwt). The 5-year relapse free survival (RFS) was 33% (95% CI:10-57) for IDHmut vs. 57% (95%CI: 30-77) for IDHwt. Progression free survival (PFS) was 25% (95%CI:1-65) IDHmut vs. 16% (95%CI: 0.7-52) IDHwt. 55% (5/9) of IDHmut G2 became higher grade at the recurrence, as compared with 25% (3/12) of G2 IDHwt. CONCLUSIONS: This study shows a higher frequency of IDH mutations in G3 CCBC as compared with G2. No significant differences in OS, RFS, and PFS by mutational status were detected. After relapse, a higher rate of G3 for IDH mutated CCBC was observed.

RESUMO

Microorganisms (sensu lato, i.e., including micrometazoans) are thought to have cosmopolitan geographic distributions due to their theoretically unlimited dispersal capabilities, a consequence of their tiny size, population dynamics, and resistant forms. However, several molecular studies of microorganisms have identified biogeographic patterns indicating cryptic speciation and/or weak species definitions. Using a multi-locus approach with the genus Milnesium (Tardigrada), we aimed to determine the genetic structure of populations worldwide and the effects of long distance dispersal (LDD) on genetic connectivity and relationships across the six continents. Our results on this micrometazoan's genetic structure and LDD at global and micro-local scales indicate contrasting patterns not easily explained by a unique or simple phenomenon. Overall, we report three key findings: (i) confirmation of long distance dispersal for tardigrades, (ii) populations with globally-shared or endemic micro-local haplotypes, and (iii) a supported genetic structure instead of the homogeneous genetic distribution hypothesized for microorganisms with LDD capabilities. Moreover, incongruences between our morphological and molecular results suggest that species delimitation within the genus Milnesium could be problematic due to homoplasy. Duality found for Milnesium populations at the global scale, namely, a molecular phylogenetic structure mixed with widely distributed haplotypes (but without any apparent biogeographic structure), is similar to patterns observed for some unicellular, prokaryotic and eukaryotic, microorganisms. Factors influencing these patterns are discussed within an evolutionary framework.

RESUMO

The complexity and heterogeneity of patients with multimorbidity and polypharmacy renders traditional disease-oriented guidelines often inadequate and complicates clinical decision making. To address this challenge, guidelines have been developed on multimorbidity or polypharmacy. To systematically analyse their recommendations, we conducted a systematic guideline review using the Ariadne principles for managing multimorbidity as analytical framework. The information synthesis included a multistep consensus process involving 18 multidisciplinary experts from seven countries. We included eight guidelines (four each on multimorbidity and polypharmacy) and extracted about 250 recommendations. The guideline addressed (i) the identification of the target population (risk factors); (ii) the assessment of interacting conditions and treatments: medical history, clinical and psychosocial assessment including physiological status and frailty, reviews of medication and encounters with healthcare providers highlighting informational continuity; (iii) the need to incorporate patient preferences and goal setting: eliciting preferences and expectations, the process of shared decision making in relation to treatment options and the level of involvement of patients and carers; (iv) individualized management: guiding principles on optimization of treatment benefits over possible harms, treatment communication and the information content of medication/care plans; (v) monitoring and follow-up: strategies in care planning, self-management and medication-related aspects, communication with patients including safety instructions and adherence, coordination of care regarding referral and discharge management, medication appropriateness and safety concerns. The spectrum of clinical and self-management issues varied from guiding principles to specific recommendations and tools providing actionable support. The limited availability of reliable risk prediction models, feasible interventions of proven effectiveness and decision aids, and limited consensus on appropriate outcomes of care highlight major research deficits. An integrated approach to both multimorbidity and polypharmacy should be considered in future guidelines.

RESUMO

Frailty has been indicated as a way for capturing biological aging of the individual and Frailty Index (FI) may serve for this purpose. This study designed the FI in a cohort of centenarians, their offspring and control subjects sex- and age-matched with offspring. The FI mean value was 0.47 (SD 0.13) in centenarians, 0.15 (SD 0.12) in their offspring, and 0.22 (SD 0.14) in controls (p < 0.001). The difference between offspring and controls was statistically significant (p = 0.003). The correlation between FI and age was significant in offspring (r = 0.46, p < 0.001), close to significance in controls (r = 0.25, p = 0.08) and not significant in centenarians. Our study confirms that FI is a marker of biological age useful to discriminate different degrees of frailty even at extremely advanced age.

RESUMO

BACKGROUND AND PURPOSE: Neuroinflammation plays a role in the aetiopathogenesis of Alzheimer's disease (AD). Triggering receptor expressed on myeloid cells 2 (TREM2), a cell surface receptor of the immunoglobulin superfamily, seems to have protective anti-inflammatory activity in AD. METHODS: Triggering receptor expressed on myeloid cells 2 expression was analysed in peripheral blood mononuclear cells from healthy subjects (CT) and from patients with either AD or mild cognitive impairment (MCI). MCI patients were re-evaluated at a 2-year follow-up to investigate their progression to AD (MCI-AD) or lack thereof (MCI-MCI). RESULTS: Triggering receptor expressed on myeloid cells 2 gene expression was higher in AD than CT patients, but was highest in MCI. At recruitment TREM2 levels were higher in MCI-AD than in MCI-MCI, and in MCI-AD were higher initially than at follow-up. TREM2 displayed a moderate degree of sensitivity and specificity for identifying MCI-AD in all MCI patients. Our data showed higher TREM2 levels in allele ε4 of apolipoprotein E (ApoE ε4) carriers than non-carriers in MCI and particularly in MCI-AD. CONCLUSIONS: These data seem to confirm the protective role of TREM2 in the pre-clinical stage of AD. Upregulation of TREM2 in MCI-AD could be a mechanism to counteract the activation of neuroinflammatory processes. It is possible that TREM2 and ApoE ε4 interact synergistically in the pre-clinical stage of AD. Therefore, TREM2 may be useful as an early peripheral biomarker for the development of AD.

RESUMO

BACKGROUND AND PURPOSE: There is now a wide consensus at recognizing social and economic circumstances as main determinants of an individual's health status. Nevertheless, characteristics relating to socioeconomic status (SES) are poorly described in research reports. The aim of the present review was to verify whether the SES of participants is adequately reported in interventional studies targeting Alzheimer's disease (AD), and to explore the impact of SES proxy measures on the efficacy of the considered medications. METHODS: A systematic review of available randomized controlled trials (RCTs) on the currently marketed drugs for AD (i.e. cholinesterase inhibitors and memantine) was conducted by performing a structured search on PubMed and the Cochrane databases. The following indicators of SES were considered in the retained studies: (i) educational level, (ii) lifetime job category, (iii) income and (iv) wealth. The study quality was assessed using the Cochrane Risk of Bias Tool for Randomized Controlled Trials. RESULTS: A total of 48 articles were finally selected. Overall, only eight RCTs reported data concerning the four considered SES indicators. Indeed, only information pertaining to the educational level of participants was provided. Only one RCT (n = 60) performed ad hoc, secondary analyses accounting for the SES of participating subjects. CONCLUSIONS: The research and clinical relevance of SES has mistakenly been overlooked by the vast majority of RCTs on AD. A greater effort should be made to collect and report data on those SES indicators that may significantly affect the clinical manifestations and trajectories of patients with cognitive disturbances.

RESUMO

AIMS: Frailty is a complex geriatric syndrome resulting in decreased physiological reserves. Frailty and polypharmacy are common in older adults and the focus of extensive studies, although little is known about the impact they may have on each other. This is the first systematic review analysing the available evidence on the relationship between frailty and polypharmacy in older adults. METHODS: Systematic review of quantitative studies. A comprehensive literature search for publications in English or Spanish was performed on MEDLINE, CINAHL, the Cochrane Database and PsycINFO in September 2017 without applying restrictions on the date of publication. Studies reporting any relationship between frailty and polypharmacy in older adults were considered. RESULTS: A total of 25 publications were included, all of them observational studies. Evaluation of Fried's frailty criteria was the most common approach, followed by the Edmonton Frail Scale and FRAIL scale. Sixteen of 18 cross-sectional analyses and five of seven longitudinal analyses demonstrated a significant association between an increased number of medications and frailty. The causal relationship is unclear and appears to be bidirectional. Our analysis of published data suggests that polypharmacy could be a major contributor to the development of frailty. CONCLUSIONS: A reduction of polypharmacy could be a cautious strategy to prevent and manage frailty. Further research is needed to confirm the possible benefits of reducing polypharmacy in the development, reversion or delay of frailty.

RESUMO

BACKGROUND: Data on temozolomide (TEM) and irinotecan (IRI) activity in recurrent Ewing sarcoma (EWS), especially in adult patients, are limited. METHODS: Patients receiving TEM 100 mg/m2/day oral, and IRI 40 mg/m2/day intravenous, days 1-5, every 21 days, were included in this multi-institutional retrospective study. Disease control rate (DCR) [overall response rate (ORR) [complete response (CR) + partial response (PR)] + stable disease (SD)], 6-months progression-free survival (6-mos PFS) and 1-year overall survival (OS) were assessed. RESULTS: The median age of the 51 patients was 21 years (range 3-65 years): 34 patients (66%) were adults (≥18 years of age), 24 (48%) had ECOG 1 and 35 (69%) were presented with multiple site recurrence. TEMIRI was used at first relapse/progression in 13 (25%) patients, while the remainder received TEMIRI for second or greater relapse/progression. Fourteen (27%) patients had received prior myeloablative therapy with busulfan and melphalan. We observed five (10%) CR, 12 (24%) PR and 19 (37%) SD, with a DCR of 71%. 6-mos PFS was 49% (95% CI 35-63) and it was significantly influenced by ECOG (6-mos PFS 64% [95% CI 45-83] for ECOG 0, 34% [95% CI 14-54] for ECOG ≥1; p = .006) and LDH (6-mos PFS 62% [95% CI 44-79] for normal LDH, 22% [95% CI 3-42] for high LDH; p = .02), with no difference according to line of treatment, age and metastatic pattern. One-year OS was 55% (95% CI 39-70), with RECIST response (p = .001) and ECOG (p = .0002) independently associated with outcome. Grade 3 and 4 toxicity included neutropenia in 12% of patients, thrombocytopenia in 4%, diarrhea in 4%. CONCLUSIONS: This series confirms the activity of TEMIRI in both adults and pediatric patients. This schedule offers a 71% DCR, independently of the line of chemotherapy. Predictive factors of response are ECOG and LDH.

RESUMO

An 81-year-old woman was hospitalised for behavioural disorders that had been progressively emerging over a period of few weeks. The symptoms appeared to worsen over time. A diagnosis of vascular dementia, complicated by psychosis, was initially hypothesised. The inefficacy of the antipsychotic/benzodiazepine medications used, along with the presence of hypertension, hypokalaemia and metabolic alkalosis (resistant to pharmacological attempts of correction), as well as the hirsutism and the development of several infections, led us to consider Cushing's syndrome. Endocrinological analysis suggested ectopic adrenocorticotropic hormone (ACTH) secretion. Although endogenous Cushing's syndrome is rare in older people, it should always be considered among the differential diagnosis of behavioural disorders.

RESUMO

BACKGROUND: Few new compounds are available for relapsed osteosarcoma. We retrospectively evaluated the activity of gemcitabine (G) plus docetaxel (D) in patients with relapsed high-grade osteosarcoma and high-grade spindle cell sarcoma of bone (HGS). METHODS: Patients receiving G 900 mg/m(2) d 1, 8; D 75 mg/m(2) d 8, every 21 days were eligible. Primary end-point: progression-free survival (PFS) at 4 months; secondary end-point: overall survival (OS) and response rate. RESULTS: Fifty-one patients were included, with a median age of 17 years (8-71), 26 (51%) were pediatric patients. GD line of treatment: 2nd in 14 patients, ≥3rd in 37. 25 (49%) patients had metastases limited to lungs, 26 (51%) multiple sites. HISTOLOGY: 40 (78%) osteosarcoma, 11 (22%) HGS. Eight (16%) patients achieved surgical complete response (sCR2) after GD. Four-month PFS rate was 46%, and significantly better for patients with ECOG 0 (ECOG 0: 54% vs ECOG 1: 43% vs ECOG 2: 0%; p = 0.003), for patients undergoing metastasectomy after GD (sCR2 75% vs no-sCR2 40 %, p = 0.02) and for osteosarcoma (osteosarcoma 56% vs HGS 18%; p = 0.05), with no differences according to age, line of treatment, and pattern of metastases. Forty-six cases had RECIST measurable disease: 6 (13%) patients had a partial response (PR), 20 (43%) had stable disease (SD) and 20 (43%) had progressive disease (PD). The 1-year OS was 30%: 67% for PR, 54% for SD and 20% for PD (p = 0.005). CONCLUSIONS: GD is an active treatment for relapsed high-grade osteosarcoma, especially for ECOG 0 patients, and should be included in the therapeutic armamentarium of metastatic osteosarcoma.

RESUMO

BACKGROUND AND AIMS: Flavonoids are a group of polyphenol compounds, ubiquitously found in plants. Great emphasis has been given to their possible benefits for cardiovascular health. These beneficial effects may be mediated by a specific action on arterial walls. Arterial stiffness is a marker of vascular aging, increasingly used in the clinical setting and assessed by pulse wave velocity. It has shown to be a robust predictor of cardiovascular events and mortality. This review aims at providing a comprehensive evaluation of available intervention and observational studies examining the relationship between flavonoid consumption and arterial stiffness. DATA SYNTHESIS: A Medline(®) literature search was performed using the keywords "arterial stiffness" and "flavonoids". As a result, 2 cross-sectional and 16 intervention studies assessing the relationship between flavonoids intake and arterial stiffness were retained. Four intervention trials reported a significant decrease of arterial stiffness after a flavonoid-based intervention, independently from blood pressure changes. The two observational studies reported significant associations between a higher flavonoid consumption and a lower arterial stiffness. In this review, isoflavones, anthocyanins and to a lesser extent cocoa flavan-3-ols appeared to be the more efficient to improve vascular function. CONCLUSIONS: Despite their heterogeneity, preliminary data seem to support an improvement of the arterial stiffness related to flavonoid intake. However, further research on absorption and dose-response effects of the specific flavonoid subclasses on arterial structure is warranted.

RESUMO

BACKGROUND: Older patients in hemodialysis have high prevalence of malnutrition that is often associated with rapid weight loss till cachexia. OBJECTIVES: We aimed to investigate whether in older patients undergoing hemodialysis the association between poor nutritional status and mortality may be independent of comorbidities and other risk factors. DESIGN: Retrospective longitudinal study. SETTING: Unit of Nephrology, Dialysis and Kidney Transplantation of the Policlinic Hospital of Milan, Milan, Italy. PARTICIPANTS: A total of 107 prevalent patients undergoing hemodialysis for at least three months. MEASUREMENTS: Sociodemographic, clinical, and biological data were recorded. Unintentional weight loss (UWL) was defined as loss of body weight > 5% in 3 months or > 10% in 6 months. We computed a 21-item Frailty Index that included clinical conditions associated with malnutrition and mortality in this population. Unadjusted and adjusted Cox proportional hazard models were performed to test the association of UWL, albumin and transferrin levels with death. Survival analyses based on Kaplan-Meier estimates were performed. RESULTS: Patients' age was 79 (±7.7) years; 38 (35%) were women. Thirty-one patients (29%) died during follow-up. Eighteen (16.8%) patients experienced UWL during the follow-up period. UWL was positively associated with death in the unadjusted model and even after the progressive inclusion of potential confounders. Low albumin levels were positively associated with death only in the unadjusted and partially adjusted models while low transferrin levels were not associated with death in none of the models. Mortality was significantly higher in those patients experiencing both UWL and albumin levels below 3.5 mg/dL. CONCLUSIONS: In older patients undergoing chronic hemodialysis UWL is associated with mortality independently of comorbidities and other risk factors. Patients presenting both UWL and low albumin levels were those experiencing the worst outcomes in terms of mortality.

RESUMO

BACKGROUND: Social vulnerability interacts with frailty and influences individuals' health status. Although frailty and social vulnerability are highly predictive of adverse outcomes, their relationship with self-perceived health(SPH) has been less investigated. METHODS: Data are from the Irish Longitudinal Study on Ageing(TILDA), a population-based longitudinal study of ageing. We included 4,222 participants aged ≥50 years (age 61.4±8.5 years;women 56%) from Wave 1 (2009-2011) followed over three longitudinal waves (2012,2014-2015,2016). Participants responded to single questions with five response options to rate their 1)physical health, 2)mental health, and 3)health compared to peers. 30-item Frailty (FI) and Social Vulnerability (SVI) indices were calculated using standardised methods. Multivariable regression analyses were performed to establish the association between FI and SVI cross-sectionally and longitudinally over 6 years. RESULTS: Cross-sectionally, SVI (mean:0.40±0.08; range:0.14-0.81) and FI (mean: 0.13±0.08; range:0.10-0.58) were modestly correlated (r=0.256), and independently associated with poor physical health (SVI: OR 1.43, 95%CI 1.15-1.78; FI: OR 3.16, 95%CI 2.54-3.93), poor mental health (SVI: OR 1.65, 95%CI 1.17-2.35; FI: OR 3.64, 95%CI 2.53-5.24), and poor health compared to peers (SVI: OR 1.41,95%CI 1.06-1.89; FI: OR 3.86, 95%CI 2.9-5.14). Longitudinally, FI and SVI were independently and positively associated with poor physical health (SVI: ß 1.08, 95%CI 0.76-1.39; FI: ß 1.97, 95%CI 1.58-2.36), poor mental health (SVI: ß 1.18, 95%CI 0.86-1.5; FI: ß 1.58, 95%CI 1.2-1.97), and poor overall health compared to peers (SVI: ß 0.78, 95%CI 0.89-1.33; FI: ß 1.74, 95%CI 0.47-1.1). CONCLUSIONS: In a large cohort of community-dwelling older adults, frailty and social vulnerability were associated with poor SPH and with risk of SPH decline over six years.

RESUMO

OBJECTIVES: Delirium is common during acute infection in older patients and is associated with functional decline. Geriatric rehabilitation (GR) can help older patients to return to their premorbid functional level. It is unknown whether delirium affects GR outcomes in patients with acute infection. We evaluated whether delirium affects trajectories of activities of daily living (ADL) and quality of life (QoL) recovery in GR after COVID-19 infection. DESIGN: This study was part of the EU-COGER study, a multicenter cohort study conducted between October 2020 and October 2021. SETTING AND PARTICIPANTS: Participants were recruited after COVID-19 infection from 59 GR centers in 10 European countries. METHODS: Data were collected at GR admission, discharge, and at the 6-week and 6-month follow-ups. Trajectories of ADL [using the Barthel index (BI)] and QoL [using the EuroQol-5 Dimensions-5 Level (EQ-5D-5L)] recovery were examined using linear mixed models. RESULTS: Of the 723 patients included (mean age 75.5 ± 9.9 years; 52.4% male), 28.9% had delirium before or during GR admission. Participants with delirium recovered in ADL at approximately the same rate as those without (linear slope effect = -0.13, SE 0.16, P = .427) up to an estimated BI score of 16.1 at 6 months. Similarly, participants with delirium recovered in QoL at approximately the same rate as those without (linear slope effect = -0.017, SE 0.015, P = .248), up to an estimated EQ-5D-5L score of 0.8 at 6 months. CONCLUSIONS AND IMPLICATIONS: Presence of delirium during the acute phase of infection or subsequent GR did not influence the recovery trajectory of ADL functioning and QoL.

RESUMO

Older persons with chronic kidney disease (CKD) undergoing hemodialysis represent a growing portion of patients characterized by high vulnerability but still marginally studied. This study aimed at exploring the relationship between the number of prescriptions and fractures in older patients with CKD undergoing hemodialysis. A 24-item Frailty Index (FI) based on sociodemographic, clinical and biological data was computed. Unadjusted and adjusted logistic regression models were performed to test the association of prescribed medications with history of fractures. A total of 107 older patients undergoing hemodialysis (38 [35.5%] women, mean age 79.1 standard deviation, SD=7.7) were included in the study. Mean number of prescribed medications was 9.9 (SD=3.9) and was significantly associated with fractures (OR 1.18, 95% CI 1.06-1.32, p=0.003), even after adjustment for potential confounders (OR 1.16, 95% CI 1.03-1.30, p=0.016). If these results will be confirmed, interventions based on deprescribing will become essential in older persons undergoing hemodialysis.

RESUMO

Preliminary data suggest that frailty tend to increase with age and is associated with fewer years of formal education. However, it is still unclear whether age and education synergistically act in the definition of frailty. Aim of the study is to evaluate the interaction between age and education in defining frailty in community-dwelling older persons. We considered 911 community-dwelling older adults (mean age 79.5 years) who underwent a comprehensive geriatric assessment. Our results showed that education and age interact in the definition of frailty following an exponential-type relationship. Whereas age is a non-modifiable risk factor, much can be done to address the social component of frailty here represented by education. The reported interaction suggests that social interventions might be particularly effective at an older age, paving the way for multidisciplinary interventions beyond the clinical field.

RESUMO

The Appetite loss in older people is an important unmet clinical need in geriatrics. The International Conference on Frailty and Sarcopenia Research (ICFSR) organized a Task Force on April 20th 2022, in Boston, to discuss issues related to appetite loss in older people, in particular, the assessment tools currently available, its evaluation in the primary care setting, and considerations about its management. There is a high heterogeneity in terms of the etiology of appetite loss in older people and a gold standard assessment tool for evaluating this condition is still absent. Although this may render difficult the management of poor appetite in clinical practice, validated assessment tools are currently available to facilitate early identification of appetite loss and support care decisions. As research on biomarkers of appetite loss progresses, assessment tools will soon be used jointly with biomarkers for more accurate diagnosis and prognosis. In addition, efforts to foster the development of drugs with a favorable risk/benefit ratio to combat poor appetite should be strengthened.

RESUMO

OBJECTIVES: Pain is one of the most common symptoms among oncological patients and has a strong negative impact on quality of life. The aim of this study is to assess if frailty and polypharmacy are associated with persistent pain in oncological patients undergoing rehabilitation. DESIGN: Observational, prospective, longitudinal study. SETTING AND PARTICIPANTS: Data are from oncological patients admitted to the Oncological Rehabilitation Unit. METHODS: Presence of pain, its intensity and characteristics were evaluated at the admission and after 7 days. A Frailty Index (FI) was computed from Comprehensive Geriatric Assessment (CGA) data. RESULTS: Among the 45 consecutively recruited patients (mean age 72 years, woman 44%), pain was present in 20 (44%) patients at the admission and 9 (20%) after 7 days of stay. Forty-one patients (92%) were taking more than 5 drugs at the admission (mean 9 drugs). The FI was normally distributed and descriptive statistics define our population as frail (mean 0.44; range 0.23-0.64). The FI was significantly associated with the presence of pain (OR 2.66; 95%CI 1.13-6.27, p=0.03) and its intensity after 7 days from the admission (ß 4.24 95% CI 1.28 - 7.19, p=0.006), even after adjustment for potential confounders. CONCLUSIONS AND IMPLICATIONS: Investigating frailty in cancer patients to implement multidisciplinary strategies could play an important role in improving persistent pain.

RESUMO

BACKGROUND: Diabetic Foot Ulcers (DFUs) are a common and feared complication of type 1 and type 2 diabetes. People with DFUs often present a significant clinical complexity due to multimorbidity, frailty, polypharmacy, and disabling conditions. Frailty, defined using the accumulation of health deficits model, has shown to predict worsening health status, hospitalizations, and death in older persons. There are no clinical studies, to date, that have examined the prevalence and effect of frailty on DFUs outcomes. The aim of our study was to explore the impact of frailty on DFUs healing and re-hospitalization in a cohort of patients hospitalized with DFUs. DESIGN: prospective cohort study. SETTING AND PARTICIPANTS: The frailty status of 76 consecutive hospitalized patients with DFUs was assessed by using the Frailty Index (FI). MEASUREMENTS: The primary outcome was the non-healing of the DFU. Secondary outcome was re-hospitalization events (for any cause) within 6 months from hospital discharge. Frailty was defined as FI>0.25. RESULTS: Out of 76 patients (median age 65 years, range 31-84), 56 (74%) were frail. At six months, 81.5% of frail patients had non-healing of the DFU compared to 55% in non-frail patients (p=0.02). The rate of of re-hospitalization was also higher in frail compared to non-frail (90.3% vs 54%, respectively; p=0.01) patients. In multivariable analyses, frailty was significantly associated with a more than fivefold increased risk of DFU non-healing [odds ratio 5.54 (95% confidence interval 1.28-23.91), p=0.02]. Similarly, re-hospitalization was also significantly higher in frail patients compared to the non-frail ones. CONCLUSIONS: In hospitalized patients with DFUs, frailty was highly prevalent. Frailty emerged as an independent risk factor for DFU non-healing and re-hospitalization events. Patients with DFUs require a comprehensive assessment of their frailty status which would enable personalization of their management and interventions.
