The severe acute respiratory syndrome (SARS-Cov-2) is a clinical entity generated by this new virus a Coronavirus (COVID-19). Disease called COVID-19 (CoronaVIrus Disease 2019) by the World Health Organization. Its presentation is acute respiratory failure characterized by hyperinflation of the lung that leads to an increase in capillaries and epithelial permeability, with loss of ventilation of lung tissue and increases lung stiffness. These disturbances lead to imbalances between ventilation and perfusion ratio, which ultimately result in hypoxemia and impaired carbon dioxide clearance. For this review, a search of PubMed and Trip Database was performed. Due to the scarcity of publications, a specific search algorithm was not used.  https://www.selleckchem.com/products/PP242.html  The objective is to review, the evidence and the recommendations of national and international experts, of the hemodynamic and ventilatory management of these patients.
  To determine the degree of depression in elderly adults after surgery and its relation with the duration of anesthesia.
 
  We conducted an observational, comparative, prospective and longitudinal study. We included 73 elderly adults aged 60 scheduled for different surgical procedures. Their degree of depression was evaluated prior to and after the surgery with the short version of the Yasavage Geriatric Depression Scale. They were classified according to the score no depression (0-5), mild depression (6-9) and established depression (10-15). The relation of depression with anesthesia duration was determined. The sample size was calculated for proportions. Descriptive statistics were used as well as χ
  (p < 0.05).
 
  In the first evaluation 47 patients (64%) were not depressed, 21 (29%) had mild depression and 5 (7%) had established depression. In the second evaluation, we found that 44 patients (60%) were not depressed, 21 (29%) had mild depression and 8 (11%) had established depression. The relation between depression and anesthesia duration was χ
  = 0.81.
 
  We did not establish a relation between depression and anesthesia duration in surgically intervened elderly adults.

  Intermittent intraoperative neuromonitoring of the recurrent laryngeal nerve is the ideal complement in thyroid surgeries, decreasing thyroid injuries.
 
  To analyze the prevalence of recurrent laryngeal nerve injuries with the use and without the use of neuromonitoring in thyroid surgery.
 
  Observational, descriptive and retrospective study, in which a total of 571 patients were included between the years 2012-2018. Of which 180 neuromonitoring was used and 391 were not used.
 
  Of the 180 patients who underwent total thyroidectomy with the use of neuromonitoring, we had a total of 8 (4.4%) transient paralysis and 2 (1.1%) definitive. Without the use of neuromonitoring we obtain 12 (3%) transient paralysis and 7 (1.85%) definitive.
 
  We believe that the use of neuromonitoring complementary to surgery should be used routinely to the usual technique. And we also obtain significant results regarding the reduction of recurrent laryngeal nerve injuries with the use of intraoperative neuromonitoring.

  To analyze the increase in sentinel cases of COVID-19 in Mexico calculated from the effective number of reproductions of the infection (R
  ) and compare its evolution with that reported by Italy, Spain and the United States of America during the first twenty weeks of evolution of the epidemic.
 
  In an analytical cross-sectional design, the total number of cases of COVID-19 in Mexico from February 29 to July 24, 2020 was studied, and compared with sentinel cases calculated from the R
  . A descriptive and comparative analysis of prevalence, cumulative incidence and case fatality was performed to summarize the epidemiological data for Mexico and in relation to information for Italy, Spain, and the United States of North America.
 
  In Mexico, until July 24, 2020, there are a total of 390,516 cases of COVID-19 and 43,680 deaths from this disease; with the use of R
  to calculate the correction of cases and unidentified deaths, the figure increases to 3,780,195 cases (p = 0.0002) and 211,469 deaths (p = 0.001). This suggests underreporting in the identification of cases and deaths and is associated with one of the highest case fatality rates in the world for SARS-CoV-2 infection.
 
  In Mexico, the sentinel model presents a significant loss of unquantified information. It is necessary to reinforce epidemiological surveillance through a better case detection strategy in our country and continue to apply measures that allow the containment and mitigation of the COVID-19 pandemic.

  Giant paraesophageal hernias have a surgical indication in case of symptoms. Since twenty years ago robot-assisted repair was incorporated to overcome the limitations of the laparoscopic surgery, and to offer new advantages.
 
  To report the experience on repairing giant paraesophageal hernias assisted by robot in a fourth level hospital in Bogotá, Colombia, Shaio Clinic.
 
  Retrospective and descriptive study of five cases of giant paraesophageal hernia type III or IV, taken to robotic correction during August 2016 to June 2018. Evaluation of post-surgery outcomes.
 
  Five paraesophageal robot-assisted repair were performed. Mean surgical time was 146 minutes, one conversion to open surgery, the average intraoperative bleeding was 100 mL, hospital stay time of 2.2 days. Morbidity, mortality and recurrence percentages in the short time were equal to 0%.
 
  Robot-assisted repair of giant paraesophageal hernias, has shown advantages that overcome the limitations of the laparoscopic approach such as dissections in difficult-to-reach angles, increased accuracy, ergonomics, three-dimensional, and closer view of the workspace.
