ReviewMacrophages in the pathophysiology of NAFLD: The role of sex differences.
Nonalcoholic fatty liver disease (NAFLD) is a multifactorial pathological condition, which recognizes a certain sexual dimorphism. Experimental and clinical studies provided evidence for a critical role of macrophages in NAFLD development and progression. Especially, liver-resident macrophages (also known as Kupffer cells) are likely the common final pathway of several pro-steatosic signals. ⋯ Sexual dimorphism then modulates metabolic and inflammatory cascades driving the liver from a simple steatosis to NAFLD and beyond. Here, metabolic and inflammatory mechanisms underlying NALFD pathophysiology will be updated. A special attention will be paid to describe sex-related differences that could provide insights for patient stratification and more tailored therapeutic approaches.

ReviewSocial vulnerability underlying disability amongst older adults: A systematic review.
Older adults face radical changes in their social life during ageing, dealing with several age-related social adaptations. The aim of this review is to systematically explore the literature on social vulnerability (SV) and its association with functional decline activity of daily living (ADL)/instrumental activities of daily living (IADL) as an endpoint in older adults. ⋯ When examining a wide set of social variables, the "quality," rather than just structure, and "type" of social relationship represents the core feature of SV that predicts functional decline in older adults. By defining individual SV, its measurement and evaluation, we can plan effective social interventions aimed at preventing or delaying functional decline or death.

ReviewNeutrophil recruitment and intracellular vesicle transport: A short overview.
Recruitment of neutrophils from the intravascular compartment into injured tissue is an essential component of the inflammatory response. It involves intracellular trafficking of vesicles within neutrophils and endothelial cells, both containing numerous proteins that have to be distributed in a tightly controlled and precise spatiotemporal fashion during the recruitment process. Rab proteins, a family of small GTPases, together with their effectors, are the key players in guiding and regulating the intracellular vesicle trafficking machinery during neutrophil recruitment. This review will provide a short overview on this process and highlight new findings as well as current controversies in the field.
