Purpose: We aimed to investigate the impact of Omicron variant infection on the perioperative organ function in patients undergoing elective surgery. Methods: A total of 5029 patients who underwent elective surgery between October 2022 and January 2023 at our hospital were enrolled. Among them, the patients who underwent elective surgery between October 2022 and November 2022 composed Group 1 (not infected with the Omicron variant) the control group; those who underwent elective surgery between December 2022 and January 2023 composed Group 2 (one month after Omicron variant infection) the experimental group. ⋯ Compared with the nontumor subgroup, fibrinogen levels, lung infection/pneumonia, TBIL, and PLT count were increased in the uninfected patients, while the globulin and eosinophil levels were decreased. Conclusion: Compared with uninfected patients, patients who underwent elective surgery one month after Omicron variant infection exhibited minimal changes in perioperative coagulation parameters, liver function, CBC counts, and kidney function. Additionally, no significant differences in postoperative mortality or LOS were observed between the two groups.

Diabetic kidney disease (DKD) is a common microvascular complication of diabetes, whose complex etiology involves a genetic component. Growth arrest-specific 5 (GAS5), a long noncoding RNA (lncRNA) gene, has been recently shown to regulate renal fibrosis. Here, we aimed to explore the potential role of GAS5 gene polymorphisms in the predisposition to DKD. ⋯ Carriers of at least one minor allele (C) of rs55829688 (TC and CC; AOR, 1.317; 95% CI, 1.023-1.696; p=0.033) more frequently suffer from advanced DKD than do those homozygotes for the major allele (TT). Furthermore, in comparison to those who do not carry the minor allele of rs55829688 (TT), advanced DKD patients possessing at least one minor allele of rs55829688 (TC and CC) exhibited a lower glomerular filtration rate, revealing an impact of rs55829688 on renal co-morbidities of diabetes. In conclusion, our data indicate an association of GAS5 gene polymorphisms with the progression of DKD.

Objective: This study aims to propose a personalized cancer prediction model based on the metabolic-inflammatory-nutritional score (MINS) for predicting lymph node metastasis (LNM) in endometrial cancer (EC) and validated prediction of survival probability in patients with a family history of Lynch syndrome-associated cancers (LSAC). Methods: A total of 676 patients diagnosed with EC were enrolled in this study. We calculated the optimal cutoff value using restricted cubic splines (RCS) analysis or the mean value. ⋯ Additionally, a nomogram was demonstrated effective predictive performance with a C-index of 0.778 (95% CI: 0.725-0.832). Conclusion: Preoperative MINS has been determined to be associated with the risk of LNM in EC patients. Utilizing MINS as a basis, the development of a prognostic nomogram holds promise as an effective tool for risk stratification in clinical settings among EC patients with a family history of LSAC.

Aim: To investigate whether it is safe for patients with Omicron variant infection to undergo surgery during perioperative period. Methods: A total of 3,661 surgical patients were enrolled: 3,081 who were not infected with the Omicron variant and 580 who were infected with the Omicron variant. We conducted propensity score matching (PSM) with a ratio of 1:4 and a caliper value of 0.1 to match the infected and uninfected groups based on 13 variables. ⋯ However, there was no statistically significant difference in the incidence rate of blood transfusion, postoperative intensive care unit transfer, lung infection/pneumonia, pleural effusion, atelectasis, respiratory failure, sepsis, postoperative deep vein thrombosis, hypoalbuminemia, urinary tract infections, and medical expenses. Conclusion: Omicron infection does not significantly increase the risk of perioperative major complications. The Omicron infection may not be a sufficient risk factor to postpone elective surgery.

Background: BMS-1166, a PD-1/PD-L1 inhibitor, inhibits the binding of PD-L1 to PD-1, restores T cell function, and enhances tumor immune response. However, mutations in the tumor suppressor or impaired cellular signaling pathways may also lead to cellular transformation. In this study, the SW480 and SW480R cell lines were used as the model to elucidate the treatment with BMS-1166, BEZ235, and their combination. ⋯ Conclusions: PD-1 binds to PD-L1 and activates the PI3K/mTOR and MAPK pathways, which might be the molecular mechanism of acquired resistance of CRC to BMS-1166. The combination of the two drugs inhibited the phosphorylation of PI3K, Akt, and Erk in the PI3K/mTOR and MAPK pathway, i.e., BEZ235 enhanced the BMS-1166 treatment effect by blocking the PI3K/mTOR pathway and interfering with the crosstalk of the MAPK pathway. Therefore, these findings provide a theoretical basis for BMS-1166 combined with BEZ235 in the trial treatment of colorectal cancer.
