RESUMO
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus is a highly contagious microorganism, and despite substantial investigation, no progress has been achieved in treating post-COVID complications. However, the virus has made various mutations and has spread around the world. Researchers have tried different treatments to reduce the side effects of the COVID-19 symptoms. One of the most common and effective treatments now used is steroid therapy to reduce the complications of this disease. Long-term steroid therapy for chronic inflammation following COVID-19 is harmful and increases the risk of secondary infection, and effective treatment remains challenging owing to fibrosis and severe inflammation and infection. Sometimes our immune system can severely damage ourselves in disease. In the past, many researchers have conducted various studies on the immunomodulatory properties of stem cells. This property of stem cells led them to modulate the immune system of autoimmune diseases like diabetes, multiple sclerosis, and Parkinson's. Because of their immunomodulatory properties, stem cell-based therapy employing mesenchymal or hematopoietic stem cells may be a viable alternative treatment option in some patients. By priming the immune system and providing cytokines, chemokines, and growth factors, stem cells can be employed to build a long-term regenerative and protective response. This review addresses the latest trends and rapid progress in stem cell treatment for Acute Respiratory Distress Syndrome (ARDS) following COVID-19.
RESUMO
BACKGROUND: The importance of gastric cancer, considering its progressive course and high mortality is one of the reasons we pay attention to patients' survival and the significance of this study was to estimate survival and determine the effective factors on patients with gastric cancer. METHODS: In this cross-sectional study, all patients with gastric cancer who underwent surgery in Shahid Beheshti Hospital, Babol, northern Iran during 2006-2011 were enrolled. To get information, a checklist was prepared consisting gender, age, and other factors related to survival from the start of diagnosis to the end of study. Statistical analysis was performed using SPSS Version 20, t-test, chi-square test and Cox regression and Kaplan-Meier. RESULTS: One hundred seventy-five patients consisting 132(75.4%) males and 43(24.6%) females entered the study. Among the 146 patients who were followed up for 50 months, 25 (14.28%) cases survived and 121 (69.15%) cases died. Survival did not have a significant association with gender, age, family history, smoking, location and type of tumor, metastasis, involved lymph nodes and treatment. Tumor stage and type of surgery had a significant association with survival in Cox regression. CONCLUSION: Diagnosis of cancer at the early stage and type of surgery increased survival rate.
