Operative versus non-operative management in acute surgical diseases during COVID-19 pandemic: a 30-day experience from an Italian hospital in Lombardy.

The spread of COVID-19 pandemic has determined a huge imbalance between real clinical needs of the population and effective resources availability. The aim of this study was to report how this situation forces surgeons to consider a non-operative management as an alternative. This is a retrospective monocentric study and we collected data from 60 patients, split in two groups: info from Group A, 28 patients (11 March to 11 April 2020) were compared with info from group B, 32 patients (11 March to 11 April 2019). The most relevant difference between the groups is related to patient's clinical management. The two groups had a considerably different number of cases that were treated with an operative management: 18 cases (64,7%) in group A vs. 28 cases (87,5%) in group B. Otherwise, non-operative approach occurred in 10 cases (35,7%) in group A and only in 4 patients (12,5%) in group B. These data suggest that the drastic reduction of means narrows the range of therapeutic choices. Indeed, in this emergency scenario, the rationing of healthcare resources was the propelling for surgeons to consider alternative therapeutic pathways.

Expanding the role of bitter taste receptor in extra oral tissues: TAS2R38 is expressed in human adipocytes.

Increasing evidence indicates that taste receptors mediate a variety of functions in extra-oral tissues. The present study investigated the expression of bitter taste receptor TAS2R38 in human adipocytes, the possible link with genetic background and the role of TAS2R38 in cell delipidation and lipid accumulation rate in vitro. Subcutaneous (SAT) and visceral (VAT) adipose tissues were collected in 32 obese and 18 lean subjects. The TAS2R38 gene expression and protein content were examined in whole tissues, differentiated adipocytes and stroma-vascular fraction cells (SVF). The P49A SNP of TAS2R38 gene was determined in each collected sample. The effect of two bitter agonists (6-n-propylthiouracil and quinine) was tested. TAS2R38 mRNA was more expressed in SAT and VAT of obese than lean subjects and the expression/protein content was greater in mature adipocytes. The expression levels were not linked to P49A variants. In in vitro differentiated adipocytes, bitter agonists induced a significant delipidation. Incubation with 6-n-propylthiouracil induced an inhibition of lipid accumulation rate together with an increase in TAS2R38 and a decrease in genes involved in adipocyte differentiation. In conclusion, TAS2R38 is more expressed in adipocytes of obese than lean subjects and is involved in differentiation and delipidation processes.
