Abstract
PURPOSE The ideal method for identifying frailty remains unclear, but the condition is associated with poor prognoses in many illnesses. Despite the availability of studies, the prognostic implications of frailty on older patients with pneumonia remains unexplored. To determine the burden and effect of frailty on selected clinical outcomes among older patients with pneumonia. METHODS We searched Medline, Google Scholar, and Science Direct databases for articles published in English following the PRISMA framework to guide our review. We included studies conducted on patients (> 60 years) with frailty and pneumonia, and reporting the effect of frailty on mortality, hospital stay, length readmission, and ICU admission. We performed a meta-analysis using STATA 14.2, calculating pooled odds ratios and 95% confidence intervals. RESULTS We analysed data from 16 studies and calculated a pooled frailty prevalence of 49% (95% CI 37-60%) in older patients with pneumonia. Unadjusted analyses revealed an odds ratio (OR) of 2.50 (95% CI 1.88-3.32) for the intermediate risk group, and an OR of 3.51 (95% CI 3.05-4.05) for the high risk group regarding mortality. The high risk frailty group also exhibited significant elevations in the risk of readmissions and extended hospital stay lengths. Substantial heterogeneity was observed in both adjusted and unadjusted analyses. CONCLUSIONS Our systematic review and meta-analysis results show that one in every two older individuals with pneumonia present frailty, a condition that significantly influences their rates of mortality and readmission, and their hospital stay length.

Risk of Atherosclerotic Cardiovascular Disease Hospitalizations after COPD Hospitalization among Older Adults. MEDRXIV : THE PREPRINT SERVER FOR HEALTH SCIENCES 2023:2023.12.19.23300254.

Abstract
BACKGROUND Meta-analyses have suggested the risk of atherosclerotic cardiovascular disease (ASCVD) events is significantly higher after a chronic obstructive pulmonary disease (COPD) exacerbation. However, these studies have been limited to highly selected patient populations potentially not generalizable to the broader population of COPD. METHODS We assessed the risk of ASCVD hospitalizations after COPD hospitalization compared to before COPD hospitalization and identified patient factors associated with ASCVD hospitalizations after COPD hospitalization. This retrospective cohort study used claims data from 920,550 Medicare beneficiaries hospitalized for COPD from 2016-2019 in the US. The primary outcome was risk of a ASCVD hospitalization composite outcome (myocardial infarction, percutaneous coronary intervention, coronary artery by-pass graft surgery, stroke, or transient ischemic attack) in the 1 year after-COPD hospitalization relative to the 1 year before-COPD hospitalization. Time from discharge to a composite ASCVD hospitalization outcome was modeled using an extension of the Cox Proportional-Hazards model, the Anderson-Gill model with adjustment for patient characteristics. Additional analyses evaluated for interactions in subgroups and risk factors associated with the composite ASCVD hospitalization outcome. RESULTS Among 920,550 patients (mean age, 73 years) the hazard ratio estimate (HR; 95% CI) for the composite ASCVD hospitalization outcome after-COPD hospitalization vs before-COPD hospitalization was 0.99 (0.97, 1.02; p = 0.53) following adjustment. We observed 3 subgroups that were significantly associated with higher risk for ASCVD hospitalizations after COPD hospitalization: 76+ years old, women, COPD hospitalization severity. Among the 19 characteristics evaluated, 10 were significantly associated with higher risk of CVD events 1 year after COPD hospitalization with hyperlipidemia (2.78; 2.67, 2.90) and history of cardiovascular disease (1.77; 1.72 1.83) associated with the greatest risk. CONCLUSION Among Medicare beneficiaries hospitalized for COPD, the risk of ASCVD hospitalizations was not significantly increased after COPD-hospitalization relative to before-COPD hospitalization. Although, we identified age 76+ years old, female sex, and COPD hospitalization severity as high risk subgroups and 10 risk factors associated with increased risk of ASCVD events after-COPD hospitalization. Further research is needed to characterize the COPD exacerbation populations at highest ASCVD hospitalization risk.

Abstract
Background Guidelines recommend that patients with myocardial infarction (MI) receive equal care regardless of age. However, withholding treatment may be justified in elderly and frail patients. This study aimed to investigate trends in treatments and outcomes of older patients with MI according to frailty. Methods and Results All patients aged ≥75 years with first-time MI during 2002 to 2021 were identified through Danish nationwide registries. Frailty was categorized using the Hospital Frailty Risk Score. One-year risk and hazard ratios (HRs) for days 0 to 28 and 29 to 365 were calculated for all-cause death. A total of 51 022 patients with MI were included (median, 82 years; 50.2% women). Intermediate/high frailty increased from 26.7% in 2002 to 2006 to 37.1% in 2017 to 2021. Use of treatment increased substantially regardless of frailty: for example, 28.1% to 48.0% (statins), 21.8% to 33.7% (dual antiplatelet therapy), and 7.6% to 28.0% (percutaneous coronary intervention) for high frailty (all P-trend <0.001). One-year death decreased for low frailty (35.1%-17.9%), intermediate frailty (49.8%-31.0%), and high frailty (62.8%-45.6%), all P-trend <0.001. Age- and sex-adjusted 29- to 365-day HRs (2017-2021 versus 2002-2006) were 0.53 (0.48-0.59), 0.62 (0.55-0.70), and 0.62 (0.46-0.83) for low, intermediate, and high frailty, respectively (P-interaction=0.23). When additionally adjusted for treatment, HRs attenuated to 0.74 (0.67-0.83), 0.83 (0.74-0.94), and 0.78 (0.58-1.05), respectively, indicating that increased use of treatment may account partially for the observed improvements. Conclusions Use of guideline-based treatments and outcomes improved concomitantly in older patients with MI, irrespective of frailty. These results indicate that guideline-based management of MI may be reasonable in the elderly and frail.

Initial Thoracic Endovascular Aortic Repair vs Medical Therapy for Acute Uncomplicated Type B Aortic Dissection. JAMA Cardiol 2023; 8:44-53. [PMID: 36334259 PMCID: PMC9637274 DOI: 10.1001/jamacardio.2022.4187] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 09/30/2022] [Indexed: 11/07/2022]
Abstract
Importance Thoracic endovascular aortic repair (TEVAR) has increasingly been used for uncomplicated type B aortic dissection (uTBAD) despite limited supporting data. Objective To assess whether initial TEVAR following uTBAD is associated with reduced mortality or morbidity compared with medical therapy alone. Design, Setting, and Participants This cohort study included Centers for Medicare & Medicaid Services inpatient claims data for adults aged 65 years or older with index admissions for acute uTBAD from January 1, 2011, to December 31, 2018, with follow-up available through December 31, 2019. Exposures Initial TEVAR was defined as TEVAR within 30 days of admission for acute uTBAD. Main Outcomes and Measures Outcomes included all-cause mortality, cardiovascular hospitalizations, aorta-related and repeated aorta-related hospitalizations, and aortic interventions associated with initial TEVAR vs medical therapy. Propensity score inverse probability weighting was used. Results Of 7105 patients with eligible index admissions for acute uTBAD, 1140 (16.0%) underwent initial TEVAR (623 [54.6%] female; median age, 74 years [IQR, 68-80 years]) and 5965 (84.0%) did not undergo TEVAR (3344 [56.1%] female; median age, 76 years [IQR, 69-83 years]). Receipt of TEVAR was associated with region (vs South; Midwest: adjusted odds ratio [aOR], 0.66 [95% CI, 0.53-0.81]; P < .001; Northeast: aOR, 0.63 [95% CI, 0.50-0.79]; P < .001), Medicaid dual eligibility (aOR, 0.76; 95% CI, 0.63-0.91; P = .003), hypertension (aOR, 1.26; 95% CI, 1.03-1.54; P = .03), peripheral vascular disease (aOR, 1.24; 95% CI, 1.02-1.49; P = .03), and year of admission (2012, 2013, 2014, and 2015 were associated with greater odds of TEVAR compared with 2011). After inverse probability weighting, mortality was similar for the 2 strategies up to 5 years (hazard ratio [HR], 0.95; 95% CI, 0.85-1.06), as were aorta-related hospitalizations (HR, 1.12; 95% CI, 0.99-1.27), aortic interventions (HR, 1.01; 95% CI, 0.84-1.20), and cardiovascular hospitalizations (HR, 1.05; 95% CI, 0.93-1.20). In a sensitivity analysis that included deaths within the first 30 days, initial TEVAR was associated with lower mortality over a period of 1 year (adjusted HR [aHR], 0.86; 95% CI, 0.75-0.99; P = .03), 2 years (aHR, 0.85; 95% CI, 0.75-0.96; P = .008), and 5 years (aHR, 0.87; 95% CI, 0.80-0.96; P = .004). Conclusions and Relevance In this study, 16.0% of patients underwent initial TEVAR within 30 days of uTBAD, and receipt of initial TEVAR was associated with hypertension, peripheral vascular disease, region, Medicaid dual eligibility, and year of admission. Initial TEVAR was not associated with improved mortality or reduced hospitalizations or aortic interventions over a period of 5 years, but in a sensitivity analysis that included deaths within the first 30 days, initial TEVAR was associated with lower mortality. These findings, along with cost-effectiveness and quality of life, should be assessed in a prospective trial in the US population.

Front Cardiovasc Med 2022; 9:1056037. [PMID: 36588580 PMCID: PMC9797732 DOI: 10.3389/fcvm.2022.1056037] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 11/30/2022] [Indexed: 12/23/2022] Open
Abstract
Background Frailty has been recognized as an important prognostic indicator in patients with acute myocardial infarction (AMI). However, no study has focused on critical AMI patients. We aimed to determine the impact of frailty on short- and long-term mortality risk in critical AMI patients. Methods Data from the Medical Information Mart for Intensive Care (MIMIC)-IV database was used. Frailty was assessed using the Hospital Frailty Risk Score (HFRS). Outcomes were in-hospital mortality and 1-year mortality. Logistic regression and Cox proportional-hazards models were used to investigate the association between frailty and outcomes. Results Among 5,003 critical AMI patients, 2,176 were non-frail (43.5%), 2,355 were pre-frail (47.1%), and 472 were frail (9.4%). The in-hospital mortality rate was 13.8%, and the 1-year mortality rate was 29.5%. In our multivariable model, frailty was significantly associated with in-hospital mortality [odds ratio (OR) = 1.30, 95% confidence interval (CI): 1.20-1.41] and 1-year mortality [hazard ratio (HR) = 1.29, 95% CI: 1.24-1.35] as a continuous variable (per five-score increase). When assessed as categorical variables, pre-frailty and frailty were both associated with in-hospital mortality (OR = 2.80, 95% CI: 2.19-3.59 and OR = 2.69, 95% CI: 1.93-3.73, respectively) and 1-year mortality (HR = 2.32, 95% CI: 2.00-2.69 and HR = 2.81, 95% CI: 2.33-3.39, respectively) after adjustment for confounders. Subgroup analysis showed that frailty was only associated with in-hospital mortality in critically ill patients with non-ST-segment elevation myocardial infarction (STEMI) but not STEMI (p for interaction = 0.012). In addition, frailty was associated with 1-year mortality in both STEMI and non-STEMI patients (p for interaction = 0.447). The addition of frailty produced the incremental value over the initial model generated by baseline characteristics for both in-hospital and 1-year mortality. Conclusion Frailty, as assessed by the HFRS, was associated with both in-hospital and 1-year mortality in critical AMI patients. Frailty improves the prediction of short- and long-term mortality in critical AMI patients and may have potential clinical applications.

Abstract
BACKGROUND Recently, several studies reported that pneumonia might increase the risk of cognitive decline and dementia due to increased frailty. OBJECTIVES This study aims to examine the association between a history of pneumonia and subsequent dementia risk. METHODS Participants were 9952 aged 65 years or older Japanese men and women from the Japan Gerontological Evaluation Study prospective cohort study, followed up from 2013 to 2019. Dementia was identified by public long-term care insurance registration. A history of pneumonia contracted 1 year before the baseline questionnaire in 2013. A cox regression model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for dementia risk, adjusted for potential confounding variables. We conducted competing risk analyses using a cause-specific hazard model. RESULTS During the follow-up period of 6 years, 939 persons developed dementia. There was no association between having a prior history of pneumonia with dementia risk (HR 1.20, 95% CI:0.81-1.78). However, we observed an increased risk of dementia in persons with pre-frailty and frailty; the multivariable HR (95% CI) was 1.75 (1.48-2.07) and 2.42 (2.00-2.93) for pre-frailty and frailty, respectively. When pneumonia and frailty were combined, the risk of dementia was the highest for the persons with a history of pneumonia and frailty; the multivariable HR (95% CI) was 2.30 (1.47-3.62). The multivariable HR (95% CI) for those without pneumonia with frailty was 1.95 (1.66-2.28). Meanwhile, the multivariable HR (95% CI) for those with pneumonia without frailty was 1.64 (0.68-3.99). CONCLUSION Our findings imply that a prior history of pre-frailty and frailty with or without pneumonia, but not a history of pneumonia per se, was associated with an increased risk of dementia among population-based-cohort of older Japanese people.

Abstract
DNA methylation (DNAm) patterns in peripheral blood have been shown to be associated with aging related health outcomes. We perform an epigenome-wide screening to identify CpGs related to frailty, defined by a frailty index (FI), in a large population-based cohort of older adults from Germany, the ESTHER study. Sixty-five CpGs are identified as frailty related methylation loci. Using LASSO regression, 20 CpGs are selected to derive a DNAm based algorithm for predicting frailty, the epigenetic frailty risk score (eFRS). The eFRS exhibits strong associations with frailty at baseline and after up to five-years of follow-up independently of established frailty risk factors. These associations are confirmed in another independent population-based cohort study, the KORA-Age study, conducted in older adults. In conclusion, we identify 65 CpGs as frailty-related loci, of which 20 CpGs are used to calculate the eFRS with predictive performance for frailty over long-term follow-up.
