Efficiency of Diagnostic Test for SARS-CoV-2 in a Nursing Home.

Background: there is no consensus on how to optimally use diagnostic tests in each stage of COVID-19 pandemic. The objective of this research is to determine the efficiency of sorting positive antibody test quarterly.

Methods: this research uses a retrospective, observational study.

Immunogenicity after 6 months of BNT162b2 vaccination in frail or disabled nursing home residents: The COVID-A Study.

Background: There is incomplete information regarding evolution of antibody titers against SARS-CoV-2 after a two-dose strategy vaccination with BNT162b2 in older adults in long-term care facilities (LTCFs) with frailty, disability, or cognitive impairment. We aimed to determine IgG antibody titer loss in older adults in LTCFs.

Methods: This is a multicenter longitudinal cohort study including 127 residents (90 females and 37 males) with a mean age of 82.

[Anemia and frailty in older adults from Spain. The FRADEA Study].

Introduction: The objective was to examine the prevalence of anemia according to the state of frailty and to analyze the relationship between anemia, hemoglobin concentration and frailty in a cohort of Spanish older adults.

Material And Methods: Cross-sectional substudy of the FRADEA (Frailty and Dependency in Albacete) cohort, a population-based concurrent cohort study conducted in people older than 69 years of Albacete (Spain). Of the 993 participants included in the first wave, 790 were selected with valid data on anemia and frailty.

Immunogenicity of the BNT162b2 vaccine in frail or disabled nursing home residents: COVID-A study.

Background/objectives: The safety and immunogenicity of the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine in older adults with different frailty and disability profiles have not been well determined. Our objective was to analyze immunogenicity of the BNT162b2 mRNA COVID-19 vaccine in older adults across frailty and disability profiles.

Design: Multicenter longitudinal cohort study.

[Anemia increases mortality risk associated with frailty or disability in older adults. The FRADEA Study].

Objective: To analyze if anemia increases 10-year mortality risk associated to frailty and disability in older adults.

Design: Substudy of the FRADEA population-based concurrent cohort study (Frailty and dependence in Albacete), with a 10-year follow-up (2007-2017) in people older than 69years.

Setting: Albacete city, Spain.

[Normal data of functional assessment tools of the elderly in Spain: the FRADEA study].

Objective: To determine the normal values of some of the functional assessment tools most used in Spain.

Design: Cross-sectional study of the first cut of a concurrent population based cohort.

Setting: Albacete city Health Area.

[Frailty and dependence in Albacete (FRADEA study): reasoning, design and methodology].

Objective: To obtain a cohort of subjects of equal to or greater than 70 years, representative of a Spanish urban population, to estimate the prevalence of frailty and follow it up over time to analyse associated factors.

Material And Methods: A prospective, population-based cohort study. From a population of 18,137 elderly persons, a representative sample of 1172 was randomly stratified, of which 993 (84.
