Objective: To investigate the differential expression of microRNA (miRNA) in patients with endometrial cancer and its relationship with prognosis and survival. Method: We used The Cancer Genome Atlas (TCGA) database to analyze differentially expressed miRNAs in endometrial cancer tissues and adjacent normal tissues. In addition, we successfully screened out key microRNAs to build nomogram models for predicting prognosis and we performed survival analysis on the key miRNAs as well. Result: We identified 187 differentially expressed miRNAs, which includes 134 up-regulated miRNAs and 53 down-regulated miRNAs. Further univariate Cox regression analysis screened out 47 significantly differentially expressed miRNAs and selected 12 miRNAs from which the prognostic nomogram model for ECA patients by LASSO analysis was constructed. Survival analysis showed that high expression of hsa-mir-138-2, hsa-mir-548f-1, hsa-mir-934, hsa-mir-940, and hsa-mir-4758 as well as low-expression of hsa-mir-146a, hsa-mir-3170, hsa-mir-3614, hsa-mir-3616, and hsa-mir-4687 are associated with poor prognosis in EC patients. However, significant correlations between the expressions levels of has-mir-876 and hsa-mir-1269a and patients’ prognosis are not found. Conclusion: Our study found that 12 significantly differentially expressed miRNAs might promote the proliferation, invasion, and metastasis of cancer cells by regulating the expression of upstream target genes, thereby affecting the prognosis of patients with endometrial cancer.

Aim: To evaluate the technical feasibility and safety of a simultaneous surgery: laparoscopic appendectomy in combination with transabdominal preperitoneal hernia repair.Methods: The study was a retrospective analytical one. The medical histories were studied and postoperative monitoring of eleven patients hospitalized with acute appendicitis who underwent simultaneous surgery: laparoscopic appendectomy with simultaneous laparoscopic plastic surgery of clinically significant inguinal hernia was carried out. During the statistical analysis, the following parameters were evaluated: the timing of postoperative recovery, the frequency of early postoperative complications and the frequency of recurrence of inguinal hernia a year after surgery.Results: The surgery was successfully performed in all 11 patients. There were no cases of infectious complications of the surgical intervention area. Acute urinary retention was registered in one patient in the early postoperative period. In one case, an early adhesive intestinal obstruction was diagnosed, which was resolved with conservative treatment. There were no cases of recurrent inguinal hernia during the year.Conclusion: laparoscopic appendectomy in combination with transabdominal preperitoneal hernia repair can be used in the treatment of acute appendicitis in combination with inguinal hernia in the absence of signs of gangrenous appendicitis with purulent peritonitis. The low statistical power of the study does not allow us to draw conclusions about the safety of this approach for patients of the older age group with a high comorbidity index.

(1) Purpose: To compare and evaluate the immediate and long-term results of the use of various hernioplasties for the treatment of inguinal hernias after surgical treatment of prostate cancer; to determine the possibility of performing transabdominal preperitoneal (TAPP) hernioplasty and total extraperitoneal (eTEP) hernioplasty in patients with inguinal hernia during surgical treatment of prostate cancer. (2) Method: This study is a clinical analytical prospective study, without the use of randomization. The study included 220 patients with inguinal hernia, who were randomly divided into two groups (group A (n = 100) and group B (n = 120)). Patients in group A received eTEP, and those in group B received TAPP. The end points of the study were the results associated with the operation itself and the prognosis of the disease in the two groups. (3) Results: Group A: five patients had a scrotal hematoma, in 10 cases nosocomial pneumonia or infectious complications from the postoperative wound. The overall rate of early postoperative complications was 15%. In group B, the following postoperative complications were reported: one case of intestinal injury, six cases of acute urinary retention, eight cases of scrotal hematoma and 12 cases of nosocomial pneumonia or infectious complications from the postoperative wound were admitted. The overall incidence of early postoperative complications was 22.5%. There was no statistically significant difference in the incidence of postoperative complications between the two groups (χ2 (3) = 2.54, p > 0.05). (4) Conclusion: During the analysis of the obtained results, no statistically significant difference was found in the duration of hospitalization, the volume of blood loss, the severity of pain syndrome, postoperative complication incidence and recurrence incidence (p > 0.05); however, the comparison groups differed in the duration of the operation: the operation time in group A was much longer compared to group B (p < 0.05).

Aim: To compare and evaluate the immediate and long-term results of performing transabdominal preperitoneal hernioplasty (TAPP) and total extraperitoneal hernioplasty (TEP) for the treatment of inguinal hernias after surgical treatment of prostate cancer;Material and method: the study is a clinical analytical prospective study, with the use of randomization. The study included 88 patients with inguinal hernia, who were randomly divided into two groups (group A (n = 44) and group B (n = 44)). Patients in group A received TEP, those in group B received TAPP. The end points of the study were the results associated with the operation itself and the prognosis of the disease in the two groups.Results: Group A: one patient had a scrotal hematoma, in 2 cases nosocomial pneumonia or infectious complications from the postoperative wound. The overall rate of early postoperative complications was 6.8%. In group B, the following postoperative complications were reported: in one case, intestinal injury, 1 case of acute urinary retention, 2 cases of scrotal hematoma. The overall incidence of early postoperative complications was 9.1%. There was no statistically significant difference in the incidence of postoperative complications between the two groups (χ = 0.009, P > 0.05).Conclusion: During the analysis of the obtained results, no statistically significant difference was found in the duration of hospitalization, the volume of blood loss and the severity of the pain syndrome (P> 0.05); however, the comparison groups differed in the duration of the operation: the operation time in group A was longer than in group B.
