Objective: We assessed the association between early HIV medical care interruption (MCI) and the development of AIDS-defining events (ADEs), serious non-AIDS events (SNAEs), and death among people with HIV (PWH) from the CoRIS cohort.
Design: We included antiretroviral-naive individuals aged at least 18 years at enrollment, recruited between 1 January 2004 and 30 May 2021, and followed-up until 30 November 2023.
Methods: Early MCI was defined as a time interval over 15 months between two consecutive visits, where the first of these visits occurred within the first 15 months of enrollment. We used Poisson regression models to assess the association between early MCI and the outcomes.
Results: Of 14 594 individuals, 1067 (7.3%) experienced an early MCI. Individuals with early MCI showed higher risk of developing ADEs (adjusted incidence rate ratio, aIRR: 2.92; 95% confidence interval (CI) 2.24-3.81) than those who did not. Early MCI was associated with a higher risk of overall mortality (2.15; 95% CI 1.75-2.64), AIDS-related deaths (3.54; 95% CI 2.35-5.44) and deaths due to liver diseases (2.44; 95% CI 1.19-4.98), but was not with mortality due to non-AIDS-defining malignancies (1.20; 95% CI 0.58-2.49). The primary underlying causes of death among individuals with early MCI were AIDS-related deaths (17%), non-AIDS-defining malignancies (11.7%) and liver diseases (10.6%).
Conclusion: Early MCI was associated with an increased rate of ADEs and death, underscoring the need to design and implement public health strategies that bolster retention in care among PWH.

Neuropsychological tests and machine learning: identifying predictors of MCI and dementia progression.

Background: Early prediction of progression in dementia is of major importance for providing patients with adequate clinical care, with considerable impact on the organization of the whole healthcare system.
Aims: The main task is tailoring robust and consolidated machine learning models to detect which neuropsychological tests are more effective in predicting a patient's mental status. In a translational medicine perspective, such identification tool should find its place in the clinician's toolbox as a support throughout his daily diagnostic routine.

Background: Biomarkers play an important role in the diagnosis of early-stage Alzheimer disease (AD), with the hippocampal emerging as the most reliable indicator of AD pathology. Elucidation of the patient's left and right hippocampal volumes warrants further consideration. Therefore, caution should be exercised regarding the constraints inherent in the measurement method.

Growth-associated protein 43 (GAP-43), a cerebrospinal fluid (CSF) marker of synaptic dysfunction, has been shown to relate to an increased risk of converting to dementia, although it is unclear whether GAP-43 alterations may be detected in pre-MCI stages. Therefore, in the present study, we examined CSF GAP-43 levels among individuals with Obj-SCD cross-sectionally and also examined whether baseline GAP-43 predicts future functional decline.

In a healthy brain, neuroinflammation, controlled by the main intermediary for the immune response microglia and astrocytes, contributes to maintain physiological functions such as secretion of neurotrophic factors, removal of cell tau and amyloid-β (Aβ) debris, and local homeostasis. When the immune response becomes chronic, it can become pathological and fuel neuroinflammation, causing glial cells to malfunction and not perform their function of clearing debris, resulting in further damage to neurons. Multiple studies highlight that an intense crosstalk is activated between peripheral blood white cells (PBWCs) and central nervous system (CNS).
