Circadian rhythm alterations affecting the pathology of neurodegenerative diseases.

The circadian rhythm is a nearly 24-h oscillation found in various physiological processes in the human brain and body that is regulated by environmental and genetic factors. It is responsible for maintaining body homeostasis and it is critical for essential functions, such as metabolic regulation and memory consolidation. Dysregulation in the circadian rhythm can negatively impact human health, resulting in cardiovascular and metabolic diseases, psychiatric disorders, and premature death.

Association between sleep problems and multimorbidity patterns in older adults.

Background: Sleep problems are frequent in older adults and are associated with chronic diseases. However, the association with multimorbidity patterns is still unknown. Considering the negative impacts that multimorbidity patterns can have on older adults' life, knowledge of this association can help in the screening and early identification of older adults with sleep problems.

Are history of falls and fear of falling associated with mobility in community-dwelling older adults?

Evidence has suggested that a history of falls and fear of falling (FOF) are associated with reduced mobility among older adults. Although many studies have explored the association between the history of falls and FOF in the context of decreased mobility, most have had small sample sizes, limiting the generalizability of the results. Therefore, this study sought to contribute to the body of knowledge around these constructs to further support the previous findings.

A nationwide study on pain manifestations and sleep problems in community-dwelling older adults: findings from ELSI-Brazil.

Purpose: Sleep problems are common and affect approximately 36-70% of older adults worldwide and can be associated with negative outcomes such as pain. There is believed to be a bidirectional relationship between sleep problems and pain, modulated by inflammation and stress. The objective was to investigate the association between self-reported sleep problems and pain manifestations.

Accuracy of handgrip and respiratory muscle strength in identifying sarcopenia in older, community-dwelling, Brazilian women.

Certain cut-off points for sarcopenia screening and diagnosis are arbitrary and based on European populations, with normative references often obtained from healthy young adults. Although respiratory skeletal muscle strength tests represent low-cost clinical measures commonly performed in clinical practice by health professionals, a gap remains regarding whether respiratory skeletal muscle strength tests are adequate and sensitive measures for sarcopenia screening. This study aimed to verify the value of handgrip and respiratory muscle strength as possible discriminators to identify sarcopenia and to establish cut-off points for sarcopenia screening in community-dwelling, Brazilian women.

Based on clinical assessment, participants were categorized in COPD (n = 43) and non-COPD (NCOPD) (n = 43) groups.

Are multimorbidity patterns associated with fear of falling in community-dwelling older adults?

Background: Multimorbidity is defined as the co-occurrence of multiple chronic or acute diseases and medical conditions in the same individual and can be grouped into different patterns based on the type of disease. These patterns are associated with poorer quality of life and premature death. It is believed that these patterns entail functional limitations, which may contribute to the fear of falling; however, this association remains unknown.

Association Between Fear of Falling and Frailty in Community-Dwelling Older Adults: A Systematic Review.

Background/objective: Fear of falling (FoF) and frailty are common problems in older adults. FoF can lead to self-imposed restriction of activities and then further decline in physical capacities that predispose older adults to frailty. Evaluating the association of these two geriatric syndromes may be the first step for understanding their complex relationship and might ultimately lead to establishing therapeutic goals and guiding treatments for older adults with frailty.
