Alzheimer's Disease May Benefit from Olive Oil Polyphenols: A Systematic Review on Preclinical Evidence Supporting the Effect of Oleocanthal on Amyloid-β Load.

Background: Mediterranean diet may enhance cognitive function and delay the progression of Alzheimer's disease (AD). We conducted a systematic review to investigate the effect of oleocanthal (OC) from extra-virgin olive oil (EVOO) on amyloid-β (Aβ) burden in preclinical models of AD, considering the anti-inflammatory and neuroprotective effects of EVOO biophenols, which are key components of the Mediterranean dietary model.

Methods: The literature was searched through six electronic databases until February 2023.

Association of Loneliness with Functional and Cognitive Status in Minor and Major Neurocognitive Disorders.

Background: Neurocognitive disorders (NCDs) have a variable decline in cognitive function, while loneliness was associated with cognitive impairment and increased dementia risk. In the present study, we examined the associations of loneliness with functional and cognitive status in patients with minor (mild cognitive impairment) and major NCDs (dementia).

Methods: We diagnosed mild NCD ( = 42) and major NCD ( = 164) through DSM-5 criteria on 206 participants aged > 65 years using the UCLA 3-Item Loneliness Scale (UCLA-3) to evaluate loneliness, the activities of daily living (ADL) and the instrumental activities of daily living (IADL) scales to measure functional status, and Mini-Mental State Examination (MMSE) to assess cognitive functions.

Antigenic sin and multiple breakthrough infections drive converging evolution of COVID-19 neutralizing responses.

Understanding the evolution of the B cell response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants is fundamental to design the next generation of vaccines and therapeutics. We longitudinally analyze at the single-cell level almost 900 neutralizing human monoclonal antibodies (nAbs) isolated from vaccinated people and from individuals with hybrid and super hybrid immunity (SH), developed after three mRNA vaccine doses and two breakthrough infections. The most potent neutralization and Fc functions against highly mutated variants belong to the SH cohort.

Dietary Intake of Polyphenols and All-Cause Mortality: A Systematic Review with Meta-Analysis.

Polyphenols are secondary metabolites found in plants, foods, and drinks, occurring in small quantities and showcasing antioxidant and anti-inflammatory qualities. The primary polyphenols consist of flavonoids, phenolic acids, stilbenes, and lignans. However, there is currently no comprehensive quantitative analysis of epidemiological data on overall death rates.

Hepatitis C epidemiology and treatment outcomes in Italy: Impact of the DAA era and the COVID-19 pandemic.

HCV infection poses a global health threat, with significant morbidity and mortality. This study examines HCV trends in a large Italian region from 2015 to 2022, considering demographic changes, evolving clinical profiles, treatment regimens and outcomes, including the impact of the COVID-19 pandemic. This multicentre retrospective study analysed demographics, clinical histories and risk factors in 6882 HCV patients.

Social Dysfunction and Apathy: Transdiagnostic Domains in Late-Life Cognitive Disorders.

Social dysfunction is a maladaptive process of coping, problem solving, and achieving one's goals. A new definition of apathy was cross-linked to social dysfunction, with a reduced goal-directed behavior and social interaction as a separate dimension. We hypothesized that these two neuropsychiatric symptoms may be included in the mild behavioral impairment diagnostic framework, operationalizing and standardizing late-life neuropsychiatric symptom assessment, to improve risk determination of dementia.

Impact of periodontal disease on cognitive disorders, dementia, and depression: a systematic review and meta-analysis.

A growing body of research suggested that there was a link between poor periodontal health and systemic diseases, particularly with the early development of cognitive disorders, dementia, and depression. This is especially true in cases of changes in diet, malnutrition, loss of muscular endurance, and abnormal systemic inflammatory response. Our study aimed to determine the extent of these associations to better target the multi-level healthy aging challenge investigating the impact of periodontal disease on cognitive disorders (cognitive impairment and cognitive decline), dementia, and depression.

PRESTIGIO RING "a 59-year-old man with multidrug resistant HIV-1 infection failing a regimen including dolutegravir, rilpivirine, atazanavir/cobicistat: successful treatment tailoring based on genotypic and phenotypic resistance tests".

Management of virological failure in heavily treatment-experienced people with multidrug-resistant (MDR) HIV infection is a serious clinical challenge. New drugs with novel mechanisms of action have recently been approved, and their use has improved the outcome of subjects with limited treatment options (LTO). In this setting, the choice of antiretroviral therapy (ART) should be tailored based on the pattern of resistance, treatment history and patients' individual characteristics.

How can we manage progressive supranuclear palsy syndrome with pharmacotherapy?

Introduction: Tauopathies are a spectrum of clinicopathological neurodegenerative disorders with increased aggregates included in glia and/or neurons of hyperphosphorylated insoluble tau protein, a microtubule-associated protein. Progressive supranuclear palsy (PSP) is an atypical dopaminergic-resistant parkinsonian syndrome, considered as a primary tauopathy with possible alteration of tau isoform ratio, and tau accumulations characterized by 4 R tau species as the main neuropathological lesions.

Areas Covered: In the present review article, we analyzed and discussed viable disease-modifying and some symptomatic pharmacological therapeutics for PSP syndrome (PSPS).

The Impact of Apolipoprotein E () Epigenetics on Aging and Sporadic Alzheimer's Disease.

Sporadic Alzheimer's disease (AD) derives from an interplay among environmental factors and genetic variants, while epigenetic modifications have been expected to affect the onset and progression of its complex etiopathology. Carriers of one copy of the apolipoprotein E gene () allele have a 4-fold increased AD risk, while -carriers have a 12-fold increased risk of developing AD in comparison with the -carriers. The main longevity factor is the homozygous ε3/ε3 genotype.

The epigenetics of frailty.

The conceptual change of frailty, from a physical to a biopsychosocial phenotype, expanded the field of frailty, including social and behavioral domains with critical interaction between different frailty models. Environmental exposures - including physical exercise, psychosocial factors and diet - may play a role in the frailty pathophysiology. Complex underlying mechanisms involve the progressive interactions of genetics with epigenetics and of multimorbidity with environmental factors.

Does Nirmatrelvir/Ritonavir Influence the Immune Response against SARS-CoV-2, Independently from Rebound?

Recurrence of coronavirus disease 19 (COVID-19) symptoms and SARS-CoV-2 viral load relapse have been reported in people treated with nirmatrelvir/ritonavir (NM/r). However, little is understood about the etiology of this phenomenon. Our aim was to investigate the relation between the host's immune response and viral rebound.

The Relationship between Oral Health-Related Quality of Life and Body Mass Index in an Older Population from Southern Italy: The Salus in Apulia Study.

Background: The assessment of oral health-related quality of life (OHRQoL) evaluated the impact of an individual's oral health on the patient's physical and psychosocial status. We evaluated the association between subjective OHRQoL, measured with the Oral Health Impact Profile-14 (OHIP-14) questionnaire, and unfavorable body mass index (BMI) (i.e.

Which Came First, Age-Related Hearing Loss with Tinnitus or Cognitive Impairment? What are the Potential Pathways?

Research on the causal relationship between age-related hearing loss (ARHL) and/or tinnitus and dementia is an important and fast-moving field. In this opinion paper, the up-to-date evidence and potential mechanisms for the bidirectional relationship are reviewed. We also present several critical factors that increase the challenges of understanding the causal relationship.

Passive tau-based immunotherapy for tauopathies.

Tauopathies are heterogeneous clinicopathological entities characterized by abnormal neuronal and/or glial inclusions of the microtubule-binding protein tau. In secondary tauopathies, i.e.

Nutritional patterns as machine learning predictors of liver health in a population of elderly subjects.

Background And Aims: Non-alcoholic hepatic steatosis affects 25% of adults worldwide and its prevalence increases with age. There is currently no definitive treatment for NAFLD but international guidelines recommend a lifestyle-based approach, including a healthy diet. The aim of this study was to investigate the interactions between eating habits and the risk of steatosis and/or hepatic fibrosis, using a machine learning approach, in a non-institutionalized elderly population.

Impact of apolipoprotein E isoforms on sporadic Alzheimer's disease: beyond the role of amyloid beta.

The impact of apolipoprotein E (ApoE) isoforms on sporadic Alzheimer's disease has long been studied; however, the influences of apolipoprotein E gene (APOE) on healthy and pathological human brains are not fully understood. ApoE exists as three common isoforms (ApoE2, ApoE3, and ApoE4), which differ in two amino acid residues. Traditionally, ApoE binds cholesterol and phospholipids and ApoE isoforms display different affinities for their receptors, lipids transport and distribution in the brain and periphery.

Clinical development of passive tau-based immunotherapeutics for treating primary and secondary tauopathies.

Introduction: Tauopathies are clinicopathological entities with increased and pathological deposition in glia and/or neurons of hyperphosphorylated aggregates of the microtubule-binding protein tau. In secondary tauopathies, i.e.
