AIM: This study analyzed the locations and circumstances of death among adults with HF in the United States using data from the CDC-WONDER database.\u0000METHODS: The study examined mortality data of individuals aged ≥20 years, with HF listed as the underlying cause of death between 1999 and 2023. The place of death was categorized as the emergency room (ER), hospice/nursing home, inpatient medical facility, or home. Multivariable logistic regression was used to determine the relationship between death location and demographic factors.\u0000RESULTS: From 1999 to 2023, HF-related deaths decreased from 1999 (3.60% and 143.6 AAMR) to 2010 (3.47% and 123.1 AAMR). From 2010 onwards, a gradual rise is seen, with the rate of HF deaths reaching 5.18% and 168.1 AAMR in 2023. Notably, deaths at home increased from 18.41% (50,648 of 275,132) in 1999 to 33.47% (132,470 of 395,826) in 2023 and deaths in hospice/nursing homes increased from 30.95% (85,144 of 275,132) in 1999 to 34.71% (116,634 of 336,014) in 2017 and then sudden fall was observed until 2023 to 29.54% (116,931 of 395,826). Older adults (65+) were more likely to die in inpatient facilities. Gender, ethnicity, and urbanization influenced the place of death, with males, whites, and those residing in large metropolitan areas more likely to die in medical facilities.\u0000CONCLUSIONS: We highlight the changing patterns in the locations of death among HF patients, emphasizing the need for improved home and hospice care services. Addressing disparities in healthcare access and enhancing palliative care are essential for improving end-of-life experiences. Further research is needed to investigate the factors that contribute to these trends.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most research has focused on high-income countries, leaving a gap in knowledge regarding the relationship between depression and CHF in low-to-middle-income countries (LMICs). This study aimed to delineate depressive symptom trajectories and identify potential risk factors for poor outcomes among CHF patients. Methods: Longitudinal data from 783 patients with CHF from public hospitals in Karachi, Pakistan was analyzed. Depressive symptom severity was assessed using the Beck Depression Inventory (BDI). Baseline and 6-month follow-up BDI scores were clustered through Gaussian Mixture Modeling to identify distinct depressive symptom subgroups and extract trajectory labels. Further, a random forest algorithm was utilized to determine baseline demographic, clinical, and behavioral predictors for each trajectory. Results: Four depressive symptom trajectories were identified: 'good prognosis,' 'remitting course,' 'clinical worsening,' and 'persistent course.' Risk factors associated with persistent depressive symptoms included lower quality of life and the New York Heart Association (NYHA) class 3 classification of CHF. Protective factors linked to a good prognosis included less disability and a non-NYHA class 3 classification of CHF. Conclusions: By identifying key characteristics of patients at heightened risk of depression, clinicians can be aware of risk factors and better identify patients who may need greater monitoring and appropriate follow-up care.

Based on LE8 scores, Cardiovascular Health (CVH) was stratified into three levels—low, moderate, and high—while AIP was categorized into four risk levels: extremely low (AIP<-0.3), low (-0.3≤AIP<0.1), medium (0.1≤AIP<0.24), and high (AIP≤0.24). Weighted ordinal logistic regression analysis was utilized to examine the association between CVH scores and AIP risk levels, adjusting for potential confounding variables. Results: A significant inverse correlation exists between CVH scores and AIP risk levels (OR=0.51, 95%CI: 0.49-0.54, P<0.001). Higher CVH scores were associated with lower AIP risk levels, while lower CVH scores corresponded to elevated AIP risk levels. Notably, improvements in specific CVH components such as Body Mass Index and Blood Lipids exhibited a strong relationship with reductions in AIP risk levels.

{"title":"Education as a Proxy for Cognitive Reserve: Moderating Effects on White Matter Hyperintensity Burden in Healthy Aging and Cognitive Decline","authors":"Iman Beheshti, odelia elkana","doi":"10.1101/2024.09.15.24313717","DOIUrl":"https://doi.org/10.1101/2024.09.15.24313717","url":null,"abstract":"Background: Cognitive reserve, often approximated by levels of education, is thought to protect against the deleterious effects of brain pathology on cognitive function. White matter hyperintensities (WMHs) are commonly associated with aging and cognitive decline, and higher WMH burden has been linked to the progression from healthy cognitive status (HC) to mild cognitive impairment (MCI). Understanding how cognitive reserve, as indicated by education, influences the relationship between WMH burden and cognitive outcomes can provide valuable insights for interventions aimed at delaying cognitive decline. Objective: This study investigates the moderating role of education, as a proxy for cognitive reserve, on the relationship between WMH burden and the transition from HC to MCI. Methods: Data were obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI) database, focusing on participants classified as cognitively healthy at baseline. A total of 153 cognitively healthy adults at the baseline were split into two groups: one group (n=85) remained cognitively healthy for at least 7 years, while the other group (n=68) progressed to MCI within 7 years. A multiple linear regression model was used to examine the interaction between group membership, baseline age, education, and sex in predicting WMH loads. The primary focus was on the interaction between group membership and education to assess the protective effect of cognitive reserve. Results: The regression model explained 18.5% of the variance in WMH load. The analysis revealed statistically significant interaction between group membership and education on WMH loads (Interaction term: β = -0.097, p = 0.047), indicating that higher education levels are associated with a reduced WMH burden among individuals who progressed to MCI. The main effect of education alone was not significant, nor were the interactions involving sex (p > 0.05). Conclusion:\u0000These findings support the hypothesis that education, as a proxy for cognitive reserve, provides a protective effect against the accumulation of WMH burden in older adults. The results suggest that higher cognitive reserve may mitigate the impact of neurodegenerative processes, thereby delaying the transition from HC to MCI. This underscores the importance of educational attainment in the preservation of cognitive health during aging.","PeriodicalId":501297,"journal":{"name":"medRxiv - Cardiovascular Medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to examine if a diverse set of biomarkers in the REHAB-HF trial would predict improvement in physical function following a 12-week tailored physical therapy rehabilitation intervention compared to attention control. Methods: The study population consisted of participants ≥60 years of age who were hospitalized with acute HF and randomized to a subsequent multidomain outpatient physical rehabilitation intervention vs. attention control with outcomes of 12-week functional change including the Short Physical Performance Battery (SPPB) and six-minute walk distance (6MWD). Blood was collected prior to randomization and at 12-weeks for cardiac, renal, and inflammatory biomarkers. Linear trends across progressively higher biomarker values versus improvement in functional outcomes based on treatment assignment were evaluated. Classification and regression trees (CART) were created to estimate optimal biomarker levels associated with differential improvement in the two functional outcomes. Results: A total of 242 of 349 participants (69%) had baseline biomarkers measured. In an adjusted regression model, higher baseline cardiac troponin (cTn) I and T were associated with greater gains in SPPB and 6MWD respectively with the rehabilitation intervention (P=0.04 and 0.03 for interaction) versus attention control. In the CART analysis of the physical rehabilitation and attention control participants, those with baseline C-reactive protein (CRP) ≥9.9 mg/L and hs-cTnT ≥36 ng/L receiving the rehabilitation intervention had a 129 m (95% CI 78-180m) greater 12-week 6MWD increase vs attention control. In contrast, for participants with CRP<9.9 mg/L there was no significant incremental 6MWD difference (30m, 95% CI -0.5m, 60.2m). For SPPB, a CRP ≥9.9 mg/L and creatinine ≥1.4 mg/dL optimally identified a differential improvement with the rehabilitation intervention versus attention control. The biomarkers (except for creatinine) decreased by 12 weeks post hospitalization but with no differences based on treatment assignment. Conclusion: Higher baseline levels of biomarkers of inflammation, cardiac injury, and renal dysfunction identified older adults after a HF hospitalization with the greatest differential improvement in physical function with a rehabilitation intervention.

The aim of the current study was to leverage human genetic evidence to inform clinical development of interleukin-6 (IL6) signaling inhibition for treatment of AAA. Methods\u0000We focused on rs2228145, a missense variant in the IL6R gene region whose associations are expressed per additional copy of the C allele, corresponding to the genetically-predicted effect of IL6 signaling inhibition. We consider genetic associations with AAA risk in the AAAgen consortium (39,221 cases, 1,086,107 controls) and UK Biobank (2215 cases, 365,428 controls). To validate against known effects of IL6 signaling inhibition, we present associations with rheumatoid arthritis, polymyalgia rheumatica, and severe COVID-19. To explore mechanism specificity, we present associations with thoracic aortic aneurysm, intracranial aneurysm, and coronary artery disease. We further evaluated associations with measures of the abdominal aorta in UK Biobank, and explored genetic associations in clinically-relevant subgroups of the population. Results\u0000We observed strong genetic associations with AAA risk in the AAAgen consortium and in UK Biobank: odds ratio (OR) 0.91 (95% confidence interval [CI]: 0.90 to 0.92, p = 4x10-30) and OR 0.90 (95% CI: 0.84, 0.96, p=0.0007), respectively. The association with AAA risk in UK Biobank was linear in the number of minor alleles: OR 0.91 (95% CI: 0.83, 1.00) in heterozygotes and OR 0.80 (95% CI: 0.71, 0.92) in minor homozygotes. The association was similar for fatal AAA, but with greater uncertainty due to the lower number of events. The association with AAA was of greater magnitude than associations with coronary artery disease and even rheumatologic disorders for which IL6 inhibitors have been approved. No strong associations were observed with thoracic aortic aneurysm, intracranial aneurysm, or abdominal aorta diameter in the general population without AAA. Associations attenuated towards the null in populations with concomitant inflammatory or connective tissue disease.

Recent work has highlighted the role of circulating lipoproteins in abdominal aortic aneurysm (AAA). We sought to triangulate human observational and genetic evidence to evaluate the role of Lp(a) in AAA.\u0000Methods: We tested the association between circulating levels of Lp(a) and clinically diagnosed abdominal aortic aneurysms while controlling for traditional AAA risk factors and levels of ApoB using logistic regression among 795 individuals with and 374,772 individuals without AAA in the UK Biobank (UKB). Multivariable Mendelian randomization (MVMR) was used to test for putatively causal associations between Lp(a) and AAA controlling for ApoB. Genetic instruments for Lp(a) and ApoB were created from genome-wide association studies (GWAS) of Lp(a) and ApoB comprising 335,796 and 418,505 UKB participants, respectively. The instruments were tested for association with AAA using data from a GWAS of 39,221 individuals with and 1,086,107 without AAA. Results: Elevated Lp(a) levels were observationally associated with an increased risk of AAA (OR 1.04 per 10 nmol/L Lp(a); 95%CI 1.02-1.05; P<0.01).
