Markers for the detection of Lewy body disease versus Alzheimer's disease in mild cognitive impairment: a systematic review and meta-analysis.

Background: Mild cognitive impairment (MCI) may evolve into dementia. Early recognition of possible evolution to Alzheimer's disease (AD) and dementia with Lewy Bodies (DLB) is of importance, but actual diagnostic criteria have some limitations. In this systematic review and meta-analysis, we aimed to find the most accurate markers that can discriminate patients with DLB versus AD, in MCI stage.

Association between multidimensional prognostic index (MPI) and infections in a population of older people affected by COVID-19.

Background: Only limited studies analyzed a possible relationship between frailty and infections. Our aim was to investigate the possible association between higher multidimensional prognostic index (MPI) values, a tool for evaluating multidimensional frailty, and the prevalence of infectious diseases, including antibiotics' cost and the prevalence of MDR (multidrug resistance) pathogens.

Methods: Older patients, affected by COVID-19, were enrolled in the hospital of Palermo over four months.

Multidimensional Frailty and Vaccinations in Older People: A Cross-Sectional Study.

It is known that influenza, herpes zoster, pneumococcal and pertussis infections may increase morbidity and mortality in older people. Vaccinations against these pathogens are effective in older adults. Frailty seems to be an important determinant of vaccination rates, yet data supporting this association are still missing.
