Background: From the first COVID-19 case in Playa del Carmen, 370 cases of infection have been reported in our staff until December 31, 2020. Material and methods: Study in workers of the General Hospital who developed SAR-CoV-2 infection during the pandemic. A sample of 30 cases of both sexes with laboratory-confirmed infection was obtained. Descriptive statistics were used with measures of central tendency, dispersion and percentages. Results: In a sample of 30 workers there were 13 doctors, 6 nurses and 11 support workers. The age was obtained as a mean of 38.8 years and SD = 10.4. Only four risk factors were found. Of the 30 infected health workers, 27 were treated on an outpatient basis and three required hospitalization. Discussion: The main symptoms in health workers are alterations in the sensation of taste and smell, but unlike our study, was headache, fever and myalgia. Likewise, it has been observed that medical are the most affected, but in this study it was support and the least affected was nursing personnel. There is no doubt that asymptomatic carriers are a serious disease transmission problem such that transmission between health workers by asymptomatic carriers is possible as was observed in this analysis.

Laparoscopic biliopancreatic diversion with duodenal switch (BPD-DS) is a technically challenging operation that requires extensive surgical dissection, transection and restoration of intestinal continuity, and advanced laparoscopic suturing skills.

This non-systematic review outlines the current knowledge concerning provenance, chemical composition and properties of apple cider vinegar, its general health effects, as well as the currently available knowledge concerning its action on fat storage, physiological mechanisms of its effects, as well as its safety and recommended dosage for treatment of obesity.

Obesity is rising worldwide, and the inflammatory disease increased in parallel. Many studies demonstrate excess fat mass is an indicator of obesity. As much as lipid increased in the cell, ROS production increased. On the other hand, ROS could enhance lipid storage and increased adiposity. So obesity and inflammation have a reciprocal relationship. Uncoupling protein2 (UCP2) could control the metabolism of energy, adipose tissue, and weight management. Also, UCP2 decreased ROS, oxidative stress, and inflammation. Therefore, as metabolism-related to oxidative stress and inflammatory status, and by considering the modulatory contribution of UCP2 in inflammation; it seems UCP2 could link obesity and inflammation. This study aims to review the studies about the association between UCP2 and obesity focusing on the inflammatory process linked to ROS. In conclusion, as the results contradict the association between UCP2 as the center of metabolism and obesity, obesity-related hormones, and oxidative stress, further studies in human trials are recommended.
