Initial Adaptation of the General Cognitive Assessment Battery by Cognifit™ for Bulgarian Older Adults

The mediation effect of treatment fatigue in the association between memory and health-related quality of life in men with HIV who have sex with men

Approximately half of all adults living with the Human Immunodeficiency Virus (HIV) experience cognitive alterations related to difficulties in treatment adherence and, therefore, to a significant decrease in quality of life. In this sense, new studies are needed to identify potential mediators related to treatment in this association, such as treatment fatigue. This fact is especially important in at specific groups of individuals with HIV, namely men with HIV who have sex with men (MSM). The objective of this study was to analyze the association between cognitive functioning, Health-Related Quality of Life (HRQoL), and treatment fatigue in MSM with HIV. A cross-sectional study was developed with a sample of 70 MSM, from the Infectious Diseases Unit of the General University Hospital of Alicante (Spain). Participants completed questionnaires related to sociodemographic data, HRQoL, and treatment fatigue in an initial phase; in a second phase, they were administered a computerized cognitive evaluation. Our results demonstrate a significant relationship between a lower cognitive performance in the memory domain and worse HRQoL. Mediation analysis has revealed the total mediation effect of treatment fatigue, specifically, the treatment cynicism domain, on this relationship. This mediation effect remained significant after controlling the sociodemographic and clinical HIV-related variables in the model. No significant mediation effects of the rest of evaluated cognitive domains (attention, perception, reasoning, or coordination) were found in this relationship. The results of this study highlight how MSM with a significant deterioration of memory are at greater risk of developing high levels of treatment fatigue, and, therefore, a lower adherence to the same and a significant deterioration in their HRQoL.

The Influence of Healthy Habits on Cognitive Functions in a Group of Hemodialysis Patients

(1) Background: Cognitive impairment (CI) is more prevalent in hemodialysis (HD) patients than in the general population. The purpose of this study was to examine if behavioral, clinical, and vascular variables are linked with CI in individuals with HD. (2) Methods: Initially, 47 individuals with chronic HD volunteered to participate in the trial, but only 27 patients ultimately completed the Montreal Cognitive Assessment (MoCA) and the Computerized Cognitive Assessment Tool (CompBased-CAT). We collected information on smoking, mental activities, physical activity (Rapid Assessment of Physical Activity, RAPA), and comorbidity. The oxygen saturation (rSO2) and pulse wave velocity (PWV; IEM Mobil-O-Graph) of the frontal lobes were measured. (3) Results: Significant associations were discovered between MoCA and rSO2 (r = 0.44, p = 0.02 and r = 0.62, p = 0.001, right/left, respectively), PWV (r = -0.69, p = 0.0001), CCI (r = 0.59, p = 0.001), and RAPA (r = 0.72, p = 0.0001). Those who actively occupied their time during dialysis and non-smokers achieved higher cognitive exam results. A multivariate regression study demonstrated that physical activity (RAPA) and PWV had separate effects on cognitive performance. (4) Conclusions: Cognitive skills are related to inter-dialysis healthy habits (physical activity, smoking) and intra-dialysis activities (tasks and mind games). Arterial stiffness, oxygenation of the frontal lobes, and CCI were linked with CI.

Personalized Computerized Training for Cognitive Dysfunction after COVID-19: A Before-and-After Feasibility Pilot Study

The current pilot study was set to evaluate the feasibility and potential benefit of a personalized computerized cognitive training (CCT) intervention to improve cognitive function among people living with post-acute sequelae of COVID-19 (PASC). Seventy three adults who self-reported cognitive dysfunction more than 3 months after a diagnosis of COVID-19 took part in an 8-week training study. Participants' general cognitive function was assessed before they completed as many cognitive daily training sessions as they wished during an 8-week period, using a personalized CCT application at home. At the end of this period, participants repeated the general cognitive function assessment. The differences between the scores at 8 weeks and baseline in five cognitive domains (attention, memory, coordination, perception, reasoning), complemented with analyses of the changes based on the participants' age, training time, self-reported health level at baseline and time since the initial COVID-19 infection. Participants had significant cognitive dysfunction and self-reported negative health levels at baseline. Most of the participants obtained higher scores after CCT in each of the domains as compared with baseline. The magnitude of this score increase was high across domains. It is concluded that a self-administered CCT based on gamified cognitive tasks could be an effective way to ameliorate cognitive dysfunction in persons with PASC. The ClinicalTrials.gov identifier is NCT05571852.

Cognitive Functioning and Its Relationship with Self-Stigma in Men with HIV Who Have Sex with Men: The Mediating Role of Health-Related Quality of Life

Introduction

The human immunodeficiency virus (HIV) stills remains a serious public health problem. HIV acquisition has several negative health consequences, such as a cognitive deterioration or health-related quality of life (HRQoL) impairment. Although these negative consequences could be directly related to a significant increase in self-stigma in this population, few previous studies have analysed the possible associations between these variables. This is especially the case in specific groups of people living with HIV, such as men who have sex with men who could be at a greater risk of stigmatisation. The main aim of the present study was to evaluate the association between cognitive functioning, HRQoL and self-stigma in a group of men with HIV who have sex with men.

Methods

The present study was conducted in the Infectious Diseases Unit of the General University Hospital of Alicante (Spain). The final sample was composed of 70 participants who passed the inclusion and exclusion criteria. All were men with HIV who had sex with men and the sample’s mean age was 45 years. Each participant completed questionnaires on HRQoL and HIV self-stigma. Moreover, they completed an online cognitive assessment through the previously validated platform for cognitive evaluation CogniFit, Inc.

Results

The obtained results showed a significant association between memory functioning impairment, lower levels of HRQoL and higher HIV self-stigma scores. Hence, HRQoL, in the mental summary domain, was shown to be a significant mediator in the relationship between low memory performance and higher HIV self-stigma.

Discussion

Neurocognitive impairment could decrease HRQoL in men with HIV who have sex with men, and hence, reinforce the idea widespread in society that having HIV holds serious consequences. This fact, together with the reduced cognitive abilities to fight against their own self-stigma could represent plausible explanations of the obtained results. In this sense, intervention strategies, oriented towards reducing cognitive impairment, such as those based on cognitive training, and other psychological interventions to promote HRQoL could be effective approaches to prevent the negative effects of HIV self-stigma in this population.
