Serum leptin levels are related to many factors, e.g. fat mass, age, smoking, serum testosterone and oestradiol levels, growth factors such as IGF-1 and CRP, and cytokines, such as IL-6 and sTNFRII. The most important of these is fat mass, as shown by multivariate analysis. Since serum leptin levels are decreased in alcohol misusers, we consider this decrease to be a consequence of a low fat mass.

The main factor related to mortality was the recovery from delirium during hospitalization. We found increased s100B serum levels in patients with delirium, but also in septic patients without delirium. This increase was not related to mortality. Geriatr Gerontol Int 2017; 17: 1161-1167.

e415while with in strain P-1-2, homogeneity was partial. Conclusion:Our study underlined role of M. pneumoniae in community-acquired LRTIs, even in children < 12 months of age. Since isolation of M. pneumoniae is rarely attempted, multilocus sequencing typing system on P1 gene, directly on respiratory specimens, may yield more refined strain differentiation.
