    Objective: To identify the association between oral health and suspected cognitive impairment in older adults in Chile. Method: Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables. Results: Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth. Conclusions: Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile.

    Galectin-3 levels in patients hospitalized for decompensated heart failure
    (Sociedad Medica de Santiago, 2017) Rossel, Víctor; Díaz-Toro, Felipe; Verdejo, Hugo; Concepción, Roberto; Sepúlveda, Luis; Castro, Pablo; Vukasovic, José Luis; Bernales, Angie
    Background: Galectin-3 (Gal-3) is a mediator of myocardial fibrosis involved in cardiac remodeling and a potential new prognosis marker in heart failure (HF). Aim: To measure Gal-3 at the moment of discharge in patients hospitalized for HF and its association with different variables. Material and Methods: Patients hospitalized for decompensated HF from four hospitals between August 2014 and March 2015, were included. Demographic, clinical and laboratory variables were recorded at the time of admission. At discharge, a blood sample was withdrawn to measure Gal-3 and brain natriuretic propeptide (Pro-BNP). Patients were separated in two groups, according to the level of Gal-3 (using a cutoff value of 17.8 ng/mL), comparing clinical and laboratory values between groups. Results: We included 52 patients with HF aged 70 ± 17 years (42% females). Functional capacity was III-IV in 46% of patients and the ejection fraction was 34.9 ± 13.4%. Pro-BNP values at discharge were 5,323 ± 8,665 pg/mL. Gal-3 values were 23.8 ± 16.6 ng/mL. Sixty percent of patients had values over 17.8 ng/mL. Those with elevated Gal-3 levels were older (75 ± 16 and 62 ± 15 years,respectively, p = 0.025) and were hypertensive in a higher proportion (90.5% and 57.1% respectively, p = 0.021). Conclusions: In patients hospitalized for HF, Gal-3 levels are higher in older and hypertensive subjects. © 2017, Sociedad Medica de Santiago. All rights reserved.

    Latent class analyses of multimorbidity and all-cause mortality: A prospective study in Chilean adults
    (Public Library of Science, 2023-01) Nazar, Gabriela; Díaz-Toro, Felipe; Concha-Cisternas, Yeny; Leiva-Ordoñez, Ana María; Troncoso-Pantoja, Claudia; Celis-Morales, Carlos; Petermann-Rocha, Fanny
    Multimorbidity patterns can lead to differential risks for all-cause mortality. Within the Chilean context, research on morbidity and mortality predominantly emphasizes individual diseases or combinations thereof, rather than specific disease clusters. This study aimed to identify multimorbidity patterns, along with their associations with mortality, within a representative sample of the Chilean population. 3,701 participants aged ≥18 from the Chilean National Health Survey 2009–2010 were included in this prospective study. Multimorbidity patterns were identified from 16 chronic conditions and then classified using latent class analyses. All-cause mortality data were extracted from the Chilean Civil Registry. The association of classes with all-cause mortality was carried out using Cox proportional regression models, adjusting by sociodemographic and lifestyle variables. Three classes were identified: a) Class 1, the healthiest (72.1%); b) Class 2, the depression/cardiovascular disease/ cancer class (17.5%); and c) Class 3, hypertension/chronic kidney disease class (10.4%). Classes 2 and 3 showed higher mortality risk than the healthiest class. After adjusting, Class 2 showed 45% higher mortality risk, and Class 3 98% higher mortality risk, compared with the healthiest class. Hypertension appeared to be a critical underlying factor of all-cause morbidity. Particular combinations of chronic diseases have a higher excess risk of mortality than others.
