Evaluating no fixation, endoscopic suture fixation, and an over-the-scope clip for anchoring fully covered self-expanding metal stents in benign upper gastrointestinal conditions: a comparative multicenter international study (With Video).

Background And Aims: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Stentfix {SF], Ovesco Endoscopy) for stent anchoring has recently been developed. The aim of this study was to evaluate the effect of OTSC fixation on FCSEMS migration rate.

Activities Carried Out during the First COVID-19 Lockdown by Italian Citizens.

The SARS-CoV-2 pandemic has altered how citizens engage in activities. This study describes the new activities citizens engaged in during the first lockdown, factors that helped them cope with the confinement, the supports they used the most, and which supports they would have liked to receive. This cross-sectional study consists of an online survey made of 49 questions that was completed by the citizens of the province of Reggio Emilia (Italy) from 4 May until 15 June 2020.

Role and challenges to digital technologies in community health promotion programs in Italy during the COVID-19 pandemic: a multiple embedded case study protocol.

Background And Aim: Due to the COVID-19 pandemics, The Italian League Against Cancer (LILT), a national federation of local associations promoting cancer prevention, had to face the challenge to find new ways and technologies to promote health in their territories. This study aims to explore how LILT associations led their health promotion interventions during the COVID-19 pandemic and to understand which interventions had a greater impact, for which population group, and why.

Methods: In this descriptive multiple embedded case study, each case will focus on the activities of a local LILT association and their collaborators on the perception and experience of the use of digital technology for health promotion and prevention, through interviews, observations, and a study of products and artifacts.

Deconstructing cold-induced brown adipocyte neogenesis in mice.

Cold exposure triggers neogenesis in classic interscapular brown adipose tissue (iBAT) that involves activation of β1-adrenergic receptors, proliferation of PDGFRA+ adipose tissue stromal cells (ASCs), and recruitment of immune cells whose phenotypes are presently unknown. Single-cell RNA-sequencing (scRNA-seq) in mice identified three ASC subpopulations that occupied distinct tissue locations. Of these, interstitial ASC1 were found to be direct precursors of new brown adipocytes (BAs).

Lipolysis regulates major transcriptional programs in brown adipocytes.

β-Adrenergic signaling is a core regulator of brown adipocyte function stimulating both lipolysis and transcription of thermogenic genes, thereby expanding the capacity for oxidative metabolism. We have used pharmacological inhibitors and a direct activator of lipolysis to acutely modulate the activity of lipases, thereby enabling us to uncover lipolysis-dependent signaling pathways downstream of β-adrenergic signaling in cultured brown adipocytes. Here we show that induction of lipolysis leads to acute induction of several gene programs and is required for transcriptional regulation by β-adrenergic signals.
