    Handgrip strength as a predictor of adverse health outcomes
    (2022) Concha-Cisternas, Yeny; Petermann-Rocha, Fanny; Castro-Pinero, Jose; Parra, Solage; Albala, Cecilia; Van De Wyngard, Vanessa; Vasquez, Jaime; Cigarroa, Igor; Celis-Morales, Carlos
    Muscle strength can be measured through different methods and handgrip strength is one of the most used techniques in epidemiological studies. Given its easy application, high reliability, and low cost, it is considered an important health biomarker. Handgrip strength is associated with adverse health outcomes such as mortality and risk of developing chronic diseases, cardiovascular, respiratory, cancer and dementia. There is a paucity of evidence in Chile about the association of handgrip strength with these health outcomes limiting its visibility and implementation in clinical settings. Therefore, this narrative review summarizes the scientific evidence about the association of grip strength with non-communicable chronic diseases and mortality in middle age and older adults.

    Hearing Loss Rehabilitation and Its Contribution to Cognitive-Linguistic Performance in Healthy Older Adults: A Systematic ReviewRehabilitación de la pérdida auditiva y su contribución al desempeño cognitivo-lingüístico en adultos mayores sanos: una revisión sistemática
    (2025) Mansilla-Jara, Francisca; Julio-Ramos, Teresa; Godoy-Díaz, Álvaro; Solomons, Daniel; Cigarroa, Igor; Toloza Ramírez, David Isaias
    Introduction. Hearing loss (HL) rehabilitation involves using different hearing technologies, such as hearing aids or cochlear implants. The efficacy of HL rehabilitation strategies and their cognitive benefits has been reported for clinical populations, such as those with mild cognitive impairment or dementia. However, up to date, there is no clarity about the cognitive-linguistic implications of HL rehabilitation for healthy older adults. Therefore, increasing knowledge about its benefits in healthy older people is critical to generating early intervention strategies that could delay the progression to pathological stages. Aim. To profile cognitive-linguistic performance after HL rehabilitation in healthy older adults. Methodology. Systematic literature review following the PRISMA guidelines. We included randomized and non-randomized clinical trials from Medline by PubMed, Scopus, and Web of Science databases (January 2000 to May 2024). Results. We identified 410 titles, from which five papers were qualitatively analyzed. Results suggest that after HL rehabilitation, healthy older adults improve their performance in specific abilities such as working memory, delayed recall, attention, semantic and phonological fluency, and language comprehension. We highlight an association between working memory improvement and semantic skills’ benefits, especially in subjects with mild to moderate HL. Conclusion. HL rehabilitation programs should consider cognitive-linguistic stimulation programs in healthy older adults to prevent cognitive dysfunction or neurodegenerative conditions. We only analyzed a few studies; thus, we suggest interpreting the information carefully. Indeed, promoting more follow-up studies to clarify the benefits of using hearing devices and their cognitive-linguistic implications in healthy people is still necessary.
