AI Article Synopsis
- The study aims to find the best combination of cognitive tests and informant reports for accurately diagnosing dementia in older adults with low education.
- Researchers assessed participants with mild to moderate dementia and older controls using various cognitive assessments and informant questionnaires.
- Results showed that a combined approach classified subjects more accurately than traditional methods, indicating that using multiple assessment tools enhances dementia screening in this demographic.
Article Abstract
Objective: To determine which combination of cognitive tests and informant reports can improve the diagnostic accuracy of dementia screening in low educated older people.
Method: Patients with mild to moderate dementia (n=34) according to ICD-10 and DSM-III-R criteria and 59 older controls were assessed with the Mini-Mental State Examination (MMSE) and the Fuld Object Memory Evaluation (FOME). Informants were assessed using the Informant Questionnaire on Cognitive Decline in the Elderly and the Bayer-Activities of Daily Living Scale.
Results: The 4 instruments combined with the mixed rule correctly classified 100% and the logistic regression (weighted sum) classified 95.7% of subjects. The weighted sum had a significantly larger ROC area compared to MMSE (p=0.008) and FOME (p=0.023). The specificity of the tested combinations was superior to the MMSE alone (p=0.002).
Conclusions: Cognitive tests combined with informant reports can improve the screening of mild to moderate dementia in low educated older people.

Background And Objectives: Lipid metabolism in older adults is affected by various factors including biological aging, functional decline, reduced physiologic reserve, and nutrient intake. The dysregulation of lipid metabolism could adversely affect brain health. This study investigated the association between year-to-year intraindividual lipid variability and subsequent risk of cognitive decline and dementia in community-dwelling older adults.

The scope of this study was to determine the diagnostic performance of ABSI for obesity and sarcopenic obesity, compared to the results of bioimpedance analysis (BIA) and BMI, by sex and age group. It involved a cross-sectional study with 12,793 participants in the second round of ELSA-Brasil (Longitudinal Study of Adult Health in Brazil), which obtained measurements of body fat percentage using BIA and anthropometry, verifying the performance of the diagnostic tests in order to compare the indices. The results showed that for obesity in men in all three age groups, the sensitivity was below 49%.

Purpose: Congenital epiphora can be related to anomalies of the nasolacrimal duct. This study aimed to assess the distal end of the nasolacrimal duct and the outcomes of endoscopic treatment in children older than 12 months with congenital epiphora.
Methods: This retrospective analysis describes the clinical characteristics, management, and outcomes of symptomatic congenital lacrimal obstruction in 32 lacrimal systems of 23 children.

This study aims to examine the prevalence of abdominal obesity-dynapenia phenotype, identified by the presence of abdominal obesity and dynapenia, and understand its associated factors with a representative sample of the Brazilian population. Data were collected from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brasil) 2015-2016. Abdominal obesity was determined by a waist-to-height ratio ≥ 0.
