Course and Lethality of SARS-CoV-2 Epidemic in Nursing Homes after Vaccination in Florence, Italy.

Evidence on the effectiveness of SARS-CoV-2 vaccines in nursing home (NHs) residents is limited. We examined the impact of the BNT162b2 mRNA SARS-CoV-2 vaccine on the course of the epidemic in NHs in the Florence Health District, Italy, before and after vaccination. Moreover, we assessed survival and hospitalization by vaccination status in SARS-CoV-2-positive cases occurring during the post-vaccination period.

Caring for nursing home residents with COVID-19: a "hospital-at-nursing home" intermediate care intervention.

Background: Nursing home (NH) residents have been dramatically affected by COVID-19, with extremely high rates of hospitalization and mortality.

Aims: To describe the features and impact of an assistance model involving an intermediate care mobile medical specialist team (GIROT, Gruppo Intervento Rapido Ospedale Territorio) aimed at delivering "hospital-at-nursing home" care to NH residents with COVID-19 in Florence, Italy.

Methods: The GIROT activity was set-up during the first wave of the pandemic (W1, March-April 2020) and became a structured healthcare model during the second (W2, October 2020-January 2021).

The complex interaction between atrial fibrillation and heart failure in elderly patients.

Heart failure (HF) and atrial fibrillation (AF) often coexist. Subjects with permanent AF show the highest prevalence of HF. Patients with incident AF have HF in a great number of cases and, reciprocally, in patients with incident HF, an AF can be frequently found.

Rate-control vs rhythm-control of atrial fibrillation in elderly patients. From new, age-oriented outcomes to a more complex management strategy.

Atrial fibrillation (AF) is the most frequent arrhythmia in elderly people. Findings derived from clinical trials seem to demonstrate that a rate-control strategy of AF in aged patients improves prognosis if compared to a rhythm-control one. However, epidemiological studies concordantly show that the arrhythmia is associated to increased hospitalization and mortality rates.

Arterial stiffness and left ventricular performance in elderly patients with persistent atrial fibrillation.

Background: The prevalence of atrial fibrillation (AF) and arterial stiffness (AS) increases with age.

Aims: To evaluate if AS is correlated to longitudinal strain (LS), a marker of left ventricular (LV) function, in elderly AF patients with preserved ejection fraction (EF) undergoing external cardioversion.

Methods: AS was measured using the cardio-ankle vascular index (CAVI), LS was calculated from echocardiographic data of three consecutive cardiac cycles.

Atrial fibrillation after electrical cardioversion in elderly patients: a role for arterial stiffness? Results from a preliminary study.

Background And Aims: Atrial fibrillation (AF) is the most frequent arrhythmia of the elderly, and electrical cardioversion (ECV) is a common procedure, although incidence of recurrences remains high. We evaluated the possible association between arterial stiffness (AS) and the persistence or recurrence of AF in elderly patients after ECV.

Methods: We enrolled all subjects undergoing ECV over a 9-month period.
