However due to the limitations of our patient population and perhaps in a lot of other sample populations in the real-world setting, it was the most feasible way to represent glucose control.The writers also suggested that the use of metformin, a potential confounder, was also not adjusted for. This should be considered in future research but addition of too many variables in a regression model may lead to less reliability of results for our study.The letter writers also suggested that the results of our paper may lead to misinterpretation by readers and may influence providers to not use insulin therapy for their patients when necessary due to fear of worse outcomes in the setting of COVID-19. We reiterated that it is very important that the data not be misinterpreted, and that nowhere in our paper did we imply or suggest that patients who need insulin therapy to treat their diabetes should not receive proper therapy due to the association we delineated in our paper.

However, recently we have shown that the gut regulates these responses. Therefore, reevaluating the role of the vagus and the CMG in the feeding responses evoked by CCK is necessary because the gut contains the highest concentration of enteric, vagal and splanchnic afferents and CCK-A receptors, which are required for reduction of food intake by this peptide, compared to other abdominal organs. To address this necessity, we injected sulfated CCK-8 (0, 0.1, 0.5, 1 and 3 nmol/kg) in the aorta, near the gastrointestinal sites of action of the peptide, in three groups of free-feeding rats (n = 10 rats per group), subdiaphragmatic vagotomy (VGX), celiaco-mesenteric ganglionectomy (CMGX) and sham-operated, and recorded seven feeding responses. In the sham group, CCK-8 reduced MS (normal chow), prolonged the intermeal interval (IMI, time between first and second meals), increased satiety ratio (SR, IMI/MS), shortened duration of first meal, reduced total (24 hrs) food intake and reduced number of meals relative to saline vehicle. Vagotomy attenuated all of the previous responses except IMI length and SR, and CMGX attenuated all of those responses. In conclusion, the feeding responses evoked by sulfated CCK-8 require, independently, the vagus nerve and the CMG.</p>","PeriodicalId":11601,"journal":{"name":"Endocrine Research","volume":"46 2","pages":"57-65"},"PeriodicalIF":2.1,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07435800.2020.1861621","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38804327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
