Moderate-to-severe cognitive impairment is associated with both recent and chronic alcohol misuse in people with HIV: The New Orleans alcohol use in HIV (NOAH) study. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024. [PMID: 38825691 DOI: 10.1111/acer.15378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 04/21/2024] [Accepted: 05/06/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND Human immunodeficiency virus (HIV) profoundly impacts the nervous system, leading to neurological deficits including HIV-associated neurocognitive disorder (HAND). HAND represents the most common neurological comorbidity among people with HIV (PWH), and alcohol use may exacerbate cognitive deficits, especially in vulnerable populations. This study investigated relationships between alcohol use and cognition in an underserved cohort of PWH, on the hypothesis that alcohol misuse exacerbates cognitive deficits. METHODS Data collected from participants (n = 259; 66.7% male; mean age 52 ± 10 years) enrolled in the New Orleans Alcohol Use in HIV (NOAH) study were utilized for cross-sectional analysis. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), and alcohol use was comprehensively measured using four metrics: the Alcohol Use Disorders Identification Test (AUDIT), 30-day timeline follow back (TLFB), lifetime drinking history, and phosphatidylethanol (PEth) levels. RESULTS The average MoCA score among participants was 20.7 ± 4.5, with 86.5% demonstrating cognitive impairment (MoCA < 26). Individuals with MoCA scores below 18 (moderately or severely cognitively impaired) had a higher frequency of recent severe alcohol misuse and greater lifetime alcohol consumption. Participants at increased risk for AUD (AUDIT ≥ 16) also had worse global cognition and memory task performance than those with lower AUDIT scores; this was particularly true among those aged 50 and older. Analysis of the MoCA sub-score data indicated that participants with increased AUD risk had impairments in the cognitive domains of language and memory. CONCLUSIONS Our findings demonstrate a high prevalence of cognitive impairment in the NOAH cohort and suggest that alcohol misuse contributes to global cognitive deficits in PWH, especially among individuals aged 50 and older. Further exploration of the impact of alcohol use on specific cognitive domains, including memory and language, should incorporate additional cognitive tasks. These findings highlight the importance of considering alcohol use and AUD risk as significant factors that may exacerbate cognitive deficits in vulnerable populations, including older PWH.

Wang T, Huang X, Dai LX, Zhan KM, Wang J. Functional connectivity alterations in the thalamus among patients with bronchial asthma. Front Neurol 2024; 15:1378362. [PMID: 38798710 PMCID: PMC11116975 DOI: 10.3389/fneur.2024.1378362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 04/15/2024] [Indexed: 05/29/2024] Open
Abstract
Objective Bronchial Asthma (BA) is a common chronic respiratory disease worldwide. Earlier research has demonstrated abnormal functional connectivity (FC) in multiple cognition-related cortices in asthma patients. The thalamus (Thal) serves as a relay center for transmitting sensory signals, yet the modifications in the thalamic FC among individuals with asthma remain uncertain. This research employed the resting-state functional connectivity (rsFC) approach to explore alterations in thalamic functional connectivity among individuals with BA. Patients and methods After excluding participants who did not meet the criteria, this study finally included 31 patients with BA, with a gender distribution of 16 males and 15 females. Subsequently, we recruited 31 healthy control participants (HC) matched for age, gender, and educational background. All participants underwent the Montreal Cognitive Assessment (MoCA) and the Hamilton Depression Rating Scale (HAMD) assessment. Following this, both groups underwent head magnetic resonance imaging scans, and resting-state functional magnetic resonance imaging (rs-fMRI) data was collected. Based on the AAL (Automated Anatomical Labeling) template, the bilateral thalamic regions were used as seed points (ROI) for subsequent rsFC research. Pearson correlation analysis was used to explore the relationship between thalamic functional connectivity and neuropsychological scales in both groups. After controlling for potential confounding factors such as age, gender, intelligence, and emotional level, a two-sample t-test was further used to explore differences in thalamic functional connectivity between the two groups of participants. Result Compared to the HC group, the BA group demonstrated heightened functional connectivity (FC) between the left thalamus and the left cerebellar posterior lobe (CPL), left postcentral gyrus (PCG), and right superior frontal gyrus (SFG). Concurrently, there was a decrease in FC with both the Lentiform Nucleus (LN) and the left corpus callosum (CC). Performing FC analysis with the right thalamus as the Region of Interest (ROI) revealed an increase in FC between the right thalamus and the right SFG as well as the left CPL. Conversely, a decrease in FC was observed between the right thalamus and the right LN as well as the left CC. Conclusion In our study, we have verified the presence of aberrant FC patterns in the thalamus of BA patients. When compared to HCs, BA patients exhibit aberrant alterations in FC between the thalamus and various brain areas connected to vision, hearing, emotional regulation, cognitive control, somatic sensations, and wakefulness. This provides further confirmation of the substantial role played by the thalamus in the advancement of BA.

Abstract
BACKGROUND Intact cognitive function is crucial for healthy aging. Functional social support is thought to protect against cognitive decline. We conducted a systematic review to investigate the association between functional social support and cognitive function in middle- and older-aged adults. METHODS Articles were obtained from PubMed, PsycINFO, Sociological Abstracts, CINAHL, and Scopus. Eligible articles considered any form of functional social support and cognitive outcome. We narratively synthesized extracted data by following the Synthesis Without Meta-Analysis (SWiM) guidelines and assessed risk of bias using the Newcastle-Ottawa Scale (NOS). RESULTS Eighty-five articles with mostly low risk-of-bias were included in the review. In general, functional social support-particularly overall and emotional support-was associated with higher cognitive function in middle- and older-aged adults. However, these associations were not all statistically significant. Substantial heterogeneity existed in the types of exposures and outcomes evaluated in the articles, as well as in the specific tools used to measure exposures and outcomes. CONCLUSIONS Our review highlights the role of functional social support in the preservation of healthy cognition in aging populations. This finding underscores the importance of maintaining substantive social connections in middle and later life.

Abstract
The current study investigates how age impacts factors associated with successfully managing HIV. One hundred thirty adults with HIV were recruited for the study. Participants were divided into two groups, those age ≥50 and those age <50. Cognitive impairment and depressive symptoms were seen at higher rates in older adults, and the severity of depressive symptoms was also higher in older adults. Depressive symptoms impacted cognitive function to a higher degree in older adults compared to younger adults (r = -0.293, p = 0.018 vs. r = -0.109, p = 0.387). Polypharmacy was a greater concern in older adults, with 88% having polypharmacy compared with 60% of younger adults. Similarly, the prevalence of comorbidities was more than double in older adults compared to younger adults. Factors associated with aging complicate management of HIV. Gaining insight into the challenges of caring for this population will furnish nurses with information necessary to provide the best possible care for this growing population.

Abstract
Objectives: To determine links between objectively and subjectively measured physical function and cognitive function among HIV-positive older adults, a growing yet understudied group with elevated risk for multimorbidity. Methods: At a biomedical research visit, 162 participants completed objective tests of gait speed (4-m walk), grip strength (dynamometer), and cognitive function (Montreal Cognitive Assessment, MoCA) and reported their well-being (Medical Outcomes Study-HIV survey). Results: Those with faster gait speed had better overall cognitive function than those with slower gait speed (b = 3.98, SE = 1.30, p = .003) in an adjusted regression model controlling for age, sex, race, height, preferred language, and assistive device use. Grip strength was not significantly associated with overall cognitive function. Self-rated cognitive function was weakly related to MoCA scores (r = .26) and gait speed (r = .14) but was strongly associated with emotional well-being (r = .53). Discussion: These observed, expected connections between physical and cognitive function could inform intervention strategies to mitigate age-related declines for older adults with HIV.
