Prevalence of transthyretin cardiac amyloidosis in elderly patients diagnosed with heart failure / Prevalencia de amiloidosis cardiaca por transtirretina en pacientes de edad avanzada con diagnóstico de insuficiencia cardiaca

Objective: There is increased interest in studying ATTR-CA, a pathology that primarily affects patients of geriatric age and is frequently underdiagnosed. We aim to establish the prevalence of ATTR-CA in a cohort of patients with a history of HFpEF and to describe its characteristics. Methods: We conducted a prospective observational study. Patients ≥75 years, clinical history of HFpEF, atrial dilation ≥34ml/m2 and left ventricular wall thickening >13mm, were included. Demographic and analytical parameters were collected, and a comprehensive geriatric assessment was performed, along with a transthoracic echocardiogram and cardiac scintigraphy. Finally, telephone follow-up was carried out at 6 and 12 months. Results: 50 patients were recruited, mean age 86±6 years, 54% women. Age and functional class (I–II vs. III–IV) were factors associated with presenting with ATTR-CA. Patients with positive scintigraphy had a median time to admission of 5.2 months (confidence interval [CI] 95% 0–10.9), while in those with negative scintigraphy, it was 12.2 months (95% CI 11.7–12.8); log-rank: p=0.064. Patients with positive scintigraphy had a median time to the combined endpoint (death and readmission) of 1.9 months (95% CI 0–6.1), and patients with negative scintigraphy of 11.9 months (95% CI 11.7–12); log-rank: p=0.027. Conclusions: ATTR-CA appears to be a prevalent etiology in elderly patients within the spectrum of HFpEF. Patients with a diagnosis of ATTR-CA had a shorter time to admission for HF and the combined event of death and admission than patients with a negative result on scintigraphy. (AU)

Objetivo: Existe un interés creciente por el estudio de AC-TTR, siendo esta una patología que afecta fundamentalmente a pacientes de edad avanzada y que es frecuentemente infradiagnosticada. Nuestro objetivo fue establecer la prevalencia de AC-TTR en una cohorte de pacientes con historia de ICFEp y describir sus características. Métodos: Estudio observacional prospectivo. Se incluyeron pacientes ≥75 años, con historia clínica de ICFEp, dilatación auricular ≥34ml/m2 y engrosamiento de la pared del ventrículo izquierdo >13mm. Se recogieron datos analíticos y demográficos, así como de la valoración geriátrica integral y se realizó un ecocardiograma transtorácico y una gammagrafía cardiaca. Finalmente se realizó seguimiento telefónico a los 6 y 12 meses. Resultados: Se incluyó a 50 pacientes, edad media 86±6 años, 54% mujeres. La edad y la clase funcional NYHA (I-II vs. III-IV) se asociaron con mayor riesgo de presentar AC-TTR. Los pacientes con gammagrafía positiva tuvieron una mediana de tiempo al ingreso de 5,2 meses (intervalo de confianza [IC] 95% 0-10,9), frente a aquellos con gammagrafía negativa que fue de 12,2 meses (IC 95% 11,7-12,8); log-rank: p=0,064. Los pacientes con gammagrafía positiva presentaron una mediana de tiempo al evento combinado (muerte y reingreso) de 1,9 meses (IC 95% 0-6,1), mientras que en aquellos con resultado negativo fue de 11,9 meses (IC 95% 11,7-12); log-rank: p=0.027. Conclusiones: La AC-TTR supone una etiología prevalente de insuficiencia cardiaca, dentro del espectro de la ICFEp, en pacientes de edad avanzada. Los individuos con diagnóstico de AC-TTR presentaron un menor tiempo al ingreso por insuficiencia cardiaca y al evento combinado de muerte y reingreso frente a aquellos pacientes con resultado negativo en la gammagrafía.

Mortality risk factors in a Spanish cohort of oldest-old patients hospitalized with COVID-19 in an acute geriatric unit: the OCTA-COVID study.

PURPOSE: To determine predictors of in-hospital mortality related to COVID-19 in oldest-old patients. DESIGN: Single-center observational study. SETTING AND PARTICIPANTS: Patients ≥ 75 years admitted to an Acute Geriatric Unit with COVID-19. METHODS: Data from hospital admission were retrieved from the electronic medical records: demographics, geriatric syndromes (delirium, falls, polypharmacy, functional and cognitive status) co-morbidities, previous treatments, clinical, laboratory, and radiographic characteristics. Cox proportional hazard models were used to evaluate in-hospital mortality. RESULTS: Three hundred patients were consecutively included (62.7% females, mean age of 86.3 ± 6.6 years). Barthel Index (BI) was < 60 in 127 patients (42.8%) and 126 (42.0%) had Charlson Index CI ≥ 3. Most patients (216; 72.7%) were frail (Clinical Frailty Scale ≥ 5) and 134 patients (45.1%) had dementia of some degree. The overall in-hospital mortality rate was 37%. The following factors were associated with higher in-hospital mortality in a multi-variant analysis: CURB-65 score = 3-5 (HR 7.99, 95% CI 3.55-19.96, p < 0.001), incident delirium (HR 1.72, 1.10-2.70, p = 0.017) and dementia (HR 3.01, 95% CI 1.37-6.705, p = 0.017). Protective factors were concurrent use of angiotensin-converting enzyme inhibitors (HR 0.42, 95% CI 0.25-0.72, p = 0.002) or prescription of hydroxychloroquine (HC 0.37 95% CI 0.22-0.62, p < 0.001) treatment during admission. CONCLUSIONS AND IMPLICATIONS: Our findings suggest that recognition of geriatric syndromes together with the CURB-65 score may be useful tools to help clinicians establish the prognosis of oldest-old patients admitted to hospital with COVID-19.

Predictive Factors of Pulmonary Embolism in Older Patients with SARS-CoV-2: The OCTA-COVID-19 Study.

BACKGROUND: The risk of pulmonary embolism (PE) has not been studied in older patients affected by COVID-19. We aimed to assess PE incidence and risk factors in a population of older patients infected with SARS-CoV-2. METHODS: An ambispective, observational cohort study. A total of 305 patients ≥ 75 years old had the SARS-CoV-2 infection from March to May 2020. The incidence rate of PE was estimated as the proportion of new cases within the whole sample. Youden's index was used to assess the cutoff point of D-dimer. To select factors associated with the risk of PE, time-to-event analyses were performed using cause-specific hazard models. RESULTS: In total, 305 patients with a median age of 87 years (62.3% female) were studied; 67.9% were referred from nursing homes and 90.4% received any type of anticoagulation. A total of 64.9% showed frailty and 44% presented with dementia. The PE incidence was 5.6%. The cutoff value of a D-dimer level over 2.59 mg/L showed a sensitivity of 82.4% and specificity of 73.8% in discriminating a PE diagnosis. In the multivariate analysis, the factors associated with PE were previous oncological events and D-dimer levels. CONCLUSIONS: The PE incidence was 5.6%, and major risk factors for PE were oncological antecedents and increased plasma D-dimer levels.

Prevalence of potentially inappropriate prescription in community-dwelling patients with advanced dementia and palliative care needs.

OBJECTIVE: To establish the prevalence of potentially inappropriate prescription (PIP) in older people with advanced dementia, monitored by a Geriatric Home Care Unit (GHC), as well as the associated risk factors and costs. METHODS: Community-dwelling patients ≥65 years with an advanced dementia diagnosis (GDS-FAST≥7a) and poor 1-year vital prognosis (Frail-VIG≥0.6) were included. Pharmacotherapy history was reviewed retrospectively, collecting functional and cognitive status, on the first GHC visit, of patients assessed January 2016-January 2019. Potentially inappropriate medication was defined following STOPP-Frail criteria. RESULTS: 100 patients included (76% women, 89.15±5.8 years). Total medications prescribed 760 (7.63±3.4 drugs per patient). 85% patients were given at least one drug considered to be PIP. 26% (196) of the total drugs registered were PIPs. Patients who were prescribed an inappropriate drug showed a higher number of total prescribed drugs (7.92±3.42 vs 6.00±2.24; p 0.04) and a higher frequency of polypharmacy (84.7% vs 60%; p 0.025). Risk of receiving inappropriate medication increased by 24% for each additional drug prescribed (OR 1.24; 95% CI 1.01-1.52; p 0.04). The costs associated with PIP were 113.99 euros per 100 patients/day; 41,606.35 euros per 100 patients/year. CONCLUSIONS: Prescription of PIP to community-dwelling patients with severe dementia and poor vital prognosis is common and is associated with high economic impact in this population group.

Efficacy of non-pharmacological interventions to treat malnutrition in older persons: A systematic review and meta-analysis. The SENATOR project ONTOP series and MaNuEL knowledge hub project.

INTRODUCTION: We aimed to perform a review of SRs of non-pharmacological interventions in older patients with well-defined malnutrition using relevant outcomes agreed by a broad panel of experts. METHODS: PubMed, Cochrane, EMBASE, and CINHAL databases were searched for SRs. Primary studies from those SRs were included. Quality assessment was undertaken using Cochrane and GRADE criteria. RESULTS: Eighteen primary studies from seventeen SRs were included. Eleven RCTs compared oral nutritional supplementation (ONS) with usual care. No beneficial effects of ONS treatment, after performing two meta-analysis in body weight changes (six studies), mean difference: 0.59 (95%CI -0.08, 1.96) kg, and in body mass index changes (two studies), mean difference: 0.31 (95%CI -0.17, 0.79) kg/m2 were found. Neither in MNA scores, muscle strength, activities of daily living, timed Up&Go, quality of life and mortality. Results of other intervention studies (dietary counselling and ONS, ONS combined with exercise, nutrition delivery systems) were inconsistent. The overall quality of the evidence was very low due to risk of bias and small sample size. CONCLUSIONS: This review has highlighted the lack of high quality evidence to indicate which interventions are effective in treating malnutrition in older people. High quality research studies are urgently needed in this area.
