Early-onset diffuse gastric cancer (EODGC) occurs at or before 50 years of age. Pathogenic mutations and germline deletions in the CDH1 gene (E-cadherin) are well-documented genetic factors associated with the causes of EODGC. ⋯ Classical pathogenic germline mutations in the CDH1 gene were not found in these 7 EODGC patients. However, the in silico approaches revealed the possible involvement of a retrovirus and a shorter E-cadherin isoform in EODGC. Nevertheless, further in vitro and in vivo assays are needed to confirm these predictions.

In severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated disease coronavirus disease 2019 (COVID-19), hypoxemia mechanisms differ from those observed in acute respiratory distress syndrome. Hypoxemia and respiratory failure in COVID- 19 are attributed to pulmonary angiopathy, increasing physiological pulmonary shunting1-3.

In the past three decades, several technologies designed for other purposes, have been applied in surgery to provide more precision to the surgical procedures and better outcomes. In surgery, innovation requires evidence before widespread implementation of novelties and a continuous quality improvement process to assess benefits and risks. ⋯ Innovation and technology should help to accomplish these conditions, but it must not be the center of surgical practice. We present here our perspective on the main issues related to technology and robotics focusing on evidence-based surgery.

The purpose of this perspective is to analyze the use of precision medicine and its potential for the next few decades with a special focus on the low- and middle-income countries, using diabetes as a paradigm. Precision medicine has improved the diagnosis, prevention, treatment, and prognosis of several malignant neoplasia. ⋯ Precision medicine has not fulfilled the expectations because it implies a long-term process composed by several feedback loops, and a number of internal and external validations and calibrations to target specific populations. If we want to obtain the expected benefits, the academic community and science agencies should work together to create the budgets and infrastructure that warrant the transfer of knowledge to the whole of society.
