Cirurgia bariátrica e câncer gástrico: uma revisão sistemática
Resumo:
: Introduction: Studies show that there is a correlation between waist circumference and visceral fat with a higher risk for cancer of the esophageal-gastric junction. The risk of gastric cancer after bariatric surgery has also not been established. The aim of this work is to conduct a systematic literature review to investigate the relation between gastric cancer and bariatric surgery Review: The research was carried out in the SciELO, MEDLINE and Google Scholar databases, using the PubMed search engine. The keywords were: "gastric cancer" AND "bariatric surgery", with selected publications from the last five years (since 2016), English or Portuguese and human trials. Discussion: A total of eight publications were selected, four of which were obtained from the MEDLINE database and four from Google Scholar. It was seen that few studies address the proposed topic, which indicates that the between gastric cancer and bariatric surgery is still little discussed and little is known about whether there is a correlation between them. Most studies suggest that post-bariatric surgery cancer is a rare condition. However, it is known that many cases are not reported or have been poorly studied, which may interfere with epidemiological data. Final considerations: There is a possibility of post-bariatric cancer, which is often not diagnosed due to nonspecific symptoms. There is a need for further studies on this relation, as the number of bariatric surgeries is increasing and at the same time incomplete data or underdiagnosis of cancer in these patients has been reported.
Keywords: gastric cancer, bariatric surgery, obesity.

Aspectos relacionados a associação entre obesidade e Covid-19: uma revisão integrativa
Resumo:
Introduction: At the end of 2019, a new type of coronavirus was identified, named SARS-CoV-2 which was found to be responsible for the disease COVID-19. Some patients develop the severe form of the disease, requiring intensive care, such as people with comorbidities. Among these comorbidities, obesity stands out, thus highlighting the importance of knowing aspects related to virus infection, especially its association with this health problem. Review: this is an integrative literature review, using databases such as LILACS, MEDLINE, SciELO and PUBMED, searched through the solutions of the following descriptors in Health Sciences (DeCS) and their correspondents in the Medical Subject Headings (Mesh): Comorbidity. Risk factors. Coronavirus infections. Obesity. Discussion: 32 articles were arranged in the light of the literature, demonstrating the relationship between obesity and SARS-CoV-2 infection. Final remarks: With the study's findings, it was possible to understand that obesity presents itself as a risk factor for severe COVID-19, these factors imply important complications and repercussions of the person with obesity: mechanical ventilation, hospitalization and intensive care
Keywords: comorbidity, risk factors, coronavirus infections, obesity.
