Faculty Opinions recommendation of Prevalence of preclinical and clinical heart failure in the elderly. A population-based study in Central Italy.

Malignant melanoma of the skin (MMS) is less than 2% (1.74%) among all malignant tumors in Russia but this is more than 10,000 (10236-2015) of new cases. It is important to monitor the trend in dynamics of morbidity and mortality from this cause. From 1995 to 2015 a number of MMS primary cases was more than doubled in absolute numbers and “crude” rates. A slightly smaller increase is indicated by standardized indicators - 62.5% for men and 70.2% for women. Annually in Russia 3670 people die from MMS (2015), which is 1.2% of all cancer deaths. In recent years the previously revealed regularities have been largely preserved: lower rates of specific gravity detected in the early stages among people in the elderly and senile and in a smaller proportion in this group who received special treatment. At the same time a change in the detailed structure of the incidence of women has been revealed where currently the leading localization of MMS was not the lower extremities but the back. The index accuracy improved however the official statistics of the distribution of patients by stages of a disease was significantly distorted (weight of the early stages was increased from the real values). The index of one-year lethality and survival was significantly improved.

SARS-CoV-2 infection fatality ratios (IFR) remain controversially discussed with implications for political measures. The German county of Tirschenreuth suffered a severe SARS-CoV-2 outbreak in spring 2020, with particularly high case fatality ratio (CFR). To estimate seroprevalence, underreported infections, and IFR for the Tirschenreuth population aged ≥14 years in June/July 2020, we conducted a population-based study including home visits for the elderly, and analyzed 4203 participants for SARS-CoV-2 antibodies via three antibody tests. Latent class analysis yielded 8.6% standardized county-wide seroprevalence, a factor of underreported infections of 5.0, and 2.5% overall IFR. Seroprevalence was two-fold higher among medical workers and one third among current smokers with similar proportions of registered infections. While seroprevalence did not show an age-trend, the factor of underreported infections was 12.2 in the young versus 1.7 for ≥85-year-old. Age-specific IFRs were <0.5% below 60 years of age, 1.0% for age 60–69, and 13.2% for age 70+. Senior care homes accounted for 45% of COVID-19-related deaths, reflected by an IFR of 7.5% among individuals aged 70+ and an overall IFR of 1.4% when excluding senior care home residents from our computation. Our data underscore senior care home infections as key determinant of IFR additionally to age, insufficient targeted testing in the young, and the need for further investigations on behavioral or molecular causes of the fewer infections among current smokers.
