Du Y, Luo Y, Ren Z, Gram LZ, Zheng X, Liu J. What impact does hearing impairment have on cognitive health in older married couples in China? Soc Sci Med 2024; 352:116999. [PMID: 38796949 DOI: 10.1016/j.socscimed.2024.116999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 04/10/2024] [Accepted: 05/16/2024] [Indexed: 05/29/2024]
Abstract
Hearing impairment is a common geriatric health problem and chronic stressor, and it is associated with poor cognitive outcomes. However, little is known about the impact of hearing impairment in married couples, particularly its potential spillover effects on the cognitive health among spouses of individuals with impairment. Drawing on a stress-proliferation perspective, we used actor-partner interdependence models to examine (1) whether an individual's hearing impairment influences their spouse's cognitive function; and (2) whether AL, symptoms of depression, and social participation serve as mediators for such an association. We utilized data from the 2015 (baseline) and 2018 (3-year follow-up) waves of the China Health and Retirement Longitudinal Study. 4434 couples were included at baseline, and 2190 couples remained after the 3-year follow-up. Hearing impairment among married women was associated with negative impacts on their spouses' cognitive function. Symptoms of depression and social participation may have served as potential mediators in this relationship. For married men, there was no statistically significant association between hearing impairment and spouses' cognitive function. Our findings suggest that hearing impairment among one spouse can lead to negative impacts on the other, but that this effect may depend on gender. Early diagnosis and couple-based interventions for hearing impairment are important for the cognitive health of both hearing-impaired individuals and their spouses.

Nutrients 2023; 15:4097. [PMID: 37836381 PMCID: PMC10574431 DOI: 10.3390/nu15194097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/13/2023] [Accepted: 09/20/2023] [Indexed: 10/15/2023] Open
Abstract
Capsaicin is a phytochemical derived from plants of the genus Capsicum and subject of intensive phytochemical research due to its numerous physiological and therapeutical effects, including its important antimicrobial properties. Depending on the concentration and the strain of the bacterium, capsaicin can exert either bacteriostatic or even bactericidal effects against a wide range of both Gram-positive and Gram-negative bacteria, while in certain cases it can reduce their pathogenicity by a variety of mechanisms such as mitigating the release of toxins or inhibiting biofilm formation. Likewise, capsaicin has been shown to be effective against fungal pathogens, particularly Candida spp., where it once again interferes with biofilm formation. The parasites Toxoplasma gondi and Trypanosoma cruzi have been found to be susceptible to the action of this compound too while there are also viruses whose invasiveness is significantly dampened by it. Among the most encouraging findings are the prospects for future development, especially using new formulations and drug delivery mechanisms. Finally, the influence of capsaicin in somatostatin and substance P secretion and action, offers an interesting array of possibilities given that these physiologically secreted compounds modulate inflammation and immune response to a significant extent.
