SARS-CoV-2 Immunization Orchestrates the Amplification of IFNγ-Producing T Cell and NK Cell Persistence.

Unlabelled: A successful vaccination would represent the most efficient means to control the pandemic of Coronavirus Disease-19 (COVID-19) that led to millions of deaths worldwide. Novel mRNA-based vaccines confer protective immunity against SARS-CoV-2, but whether immunity is immediately effective and how long it will remain in recipients are uncertain. We sought to assess the effectiveness of a two-dose regimen since the boosts are often delayed concerning the recommended intervals.

Occupational Exposure in the Lombardy Region (Italy) to SARS-CoV-2 Infection: Results from the MUSTANG-OCCUPATION-COVID-19 Study.

Sero-epidemiological surveys are valuable attempts to estimate the circulation of SARS-CoV-2 in general or selected populations. Within this context, a prospective observational study was conducted to estimate the prevalence and persistence of SARS-CoV-2 antibodies in different categories of workers and factors associated with positivity, through the detection of virus-specific immunoglobulin G and M (IgG/IgM) in serum samples. Enrollees were divided in low exposure and medium-high groups on the basis of their work activity.

Blood pressure control in type 2 diabetes mellitus with arterial hypertension. The important ancillary role of SGLT2-inhibitors and GLP1-receptor agonists.

Type 2 diabetes mellitus and arterial hypertension are major cardiovascular risks factors which shares metabolic and haemodynamic abnormalities as well as pathophysiological mechanisms. The simultaneous presence of diabetes and arterial hypertension increases the risk of left ventricular hypertrophy, congestive heart failure, and stroke, as compared to either condition alone. A number of guidelines recommend lifestyle measures such as salt restriction, weight reduction and ideal body weight mainteinance, regular physical activity and smoking cessation, together with moderation of alcohol consumption and high intake of vegetables and fruits, as the basis for reduction of blood pressure and prevention of CV diseases.

AnatoMy and physIopathoLogy of the heArt in a ceNtenarian cOhort (MILANO study).

Background: Centenarians are increasingly being encountered in clinical practice. The aim of the study was to characterize centenarians' clinical features and cardiovascular system.

Methods: A prospective, observational, cross-sectional, case-control study included 118 hospitalized >100-year-old patients compared to 50 octogenarians, selected in Milan (Italy) from December 2010 to December 2017, to assess their clinical and echocardiographic characteristics.

Ventricular-arterial coupling in centenarians without cardiovascular diseases.

Background: Ventricular-arterial (VA) coupling is a central determinant of cardiovascular system performance and cardiac energetics. This index is expressed by the Ea/Ees ratio, where the effective arterial elastance (Ea) indicates the net arterial load exerted on the left ventricle and the left ventricular end-systolic elastance (Ees) is a load-independent measure of left ventricular chamber performance.

Methods: Thirty-three centenarians (100.
